Description:

APPARATUS FOR SORTING CAPS

TECHNICAL FIELD

The present invention relates to an apparatus for sorting caps,

and more particularly, to an apparatus for sorting caps'which is capable

of dispersing and aligning pump/dosing pump caps to effectively sort

them.

BACKGROUND ART

A dispenser cap or a pump cap is used for discharging a liquid

from a liquid container. The dispenser cap is used for a shampoo

container or a rinse container. When the dispenser cap is depressed, a

predetermined amount of liquid is discharged. The pump cap is used

for a perfume container or a spray container. When the pump cap is

depressed, a small amount of liquid is sprayed and discharged. The

pump/dosing pump cap is a dispenser cap, a pump cap, and so forth,

which discharges a liquid to the outside.

After the liquid is contained in the liquid container, the liquid

container is combined with the pump/dosing pump cap. Such a method

is employed in the manufacture of shampoo products, rinse products,

and so forth. In general, the pump/dosing pump cap has a cap body

with an outlet, and a suction pipe connected to a lower portion of the cap

body. The suction pipe communicates with the outlet and is elongated.

When the liquid container is operated, the suction pipe sucks the liquid

below to have it discharged through the upper outlet. As such, the

pump/dosing pump cap has an elongated shape as a whole.

When the shampoo product or the rinse product is manufactured,

it is preferable to align the pump/dosing pump caps and supply them in

order to facilitate combination of the pump/dosing pump cap and the

liquid container. That is, it is preferable to correctly orientate and supply

the pump/dosing pump caps. To this end, an apparatus for sorting caps

has been developed that can correctly orientate and supply a large

number of pump/dosing pump caps.

The apparatus for sorting caps that has been used in the related

art is composed of a cap loading section for supplying the caps and a

cap sorting section for sorting the caps. The manufactured cap sorting

section has a rotational disc plate for separating the large number of

amassed caps. A large number of holders are mounted along a

circumference of the disc plate, and the cap sorting section rotates the

disc plate to separate the amassed caps. Rotation of the disc plate

enables the caps to be individually separated by the holders. The

separated caps are then sequentially transferred so that the shampoo

product or the rinse product can be manufactured.

However, when such a rotational type of cap sorting section is

employed, there is a problem in that the number of caps that are capable

of being sorted per minute is limited to about eighty due to its capacity

limitation. There also exists a limit in the shape of the caps that can be

sorted. In addition, the caps are deviated due to centrifugal force so

that the efficiency is degraded. Further, the caps often stick in the cap

sorting section such that operation of the cap sorting section must be

stopped often, and impacts due to centrifugal force cause the caps to be

damaged.

BEST MODES FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be

described with reference to Figs. 1 to 16. These embodiments are

employed for exemplary purposes only and are not limited thereto.

Fig. 1 illustrates an apparatus for sorting caps 100 in accordance

with an embodiment of the present invention. An exemplary structure of

the apparatus for sorting caps is shown in Fig. 1 , but the present

invention is not limited thereto.

The apparatus for sorting caps 100 includes a cap transfer

section 10, a cap sorting section 20, and a cap supply section 30. The

apparatus further includes a casing 90 surrounding the components.

Pump/dosing pump caps C supplied from the cap supply section 30 are

sorted by the cap sorting section 20, and are then transferred to the next

process by the cap transfer section 10.

The cap supply section 30 supplies the pump/dosing pump caps

C to the cap sorting section 20. The cap supply section 30 enables the

pump/dosing pump caps C to be smoothly supplied. The cap supply

section 30 includes a conveyor belt 301 and a guide plate 311. The cap

supply section may further include a cap dispersing section 313.

Motors (not shown) disposed at both ends of the conveyor belt

301 enable the conveyor belt 301 to move in the direction denoted by an

arrow. Accordingly, the pump/dosing pump caps C on the conveyor belt

301 can be supplied to the cap sorting section 20. A plurality of guide

plates 311 are mounted on the conveyor belt 301. In order to prevent

the guide plates 311 from being in contact with the conveyor belt 301 ,

support rods 312 are mounted to fix the guide plates 311. The support

rods 12 fix the guide plates 311 along the direction where the guide

plates 311 are arranged. For example, as shown in Fig. 1 , the support

rods 312 may penetrate the upper portions of the guide plates 311 to fix

the guide plates 311. The support rods 312 are fixed to the casing 90,

so that they can securely fix the guide plates 311.

A plurality of the guide plates 311 are spaced apart from each

other on the conveyor belt 301. The guide plates 311 separate the

plurality of pump/dosing pump caps C to guide them toward the cap

sorting section 20. In particular, the guide plates 311 align the

pump/dosing pump caps C to guide them toward the cap sorting section

20, so that the pump/dosing pump caps C can be raised in a safe way by

the cap sorting section 20.

The cap sorting section 20 raises the pump/dosing pump caps C

to supply them to the cap transfer section 10. An inclination angle (θ) of

the cap sorting section 20 preferably ranges from 45° to 90°. The cap

sorting section 20 is inclined by such an angle so that the pump/dosing

pump caps C can be safely raised. When the inclination angle of the

cap sorting section 20 is less than 45° or exceeds 90°, there is a problem

that the pump/dosing pump caps C cannot be safely fixed.

The cap sorting section 20 include a plurality of lifters 201 and a

conveyor belt 211. Motors (not shown) are mounted on both ends of the

conveyor belt 211 to raise the conveyor belt 211 in a direction denoted by

an arrow. A stop sensor (not shown) and a speed adjustment sensor

(not shown) are mounted on the conveyor belt 211 , so that a return

speed of the pump/dosing pump cap C can be freely adjusted. The

plurality of lifters 201 are mounted on the conveyor belt 211. The lifters

201 extend in a width direction (i.e., an X axis direction) of the conveyor

belt 211. Accordingly, the pump/dosing pump caps C can be aligned

with and raised in the X axis direction side by side.

The apparatus for sorting caps 100 according to the embodiment

of the present invention includes a cap erection section 220, a cap

removal section 240, and a cap return section 40, which act to align or

discharge unaligned pump/dosing pump caps C to the outside. The cap

erection section 220 and the cap removal section 240 correctly align the

unaligned pump/dosing pump caps C. The cap erection section 220

and the cap removal section 240 are fixed to the casing 90 that

surrounds the cap sorting section 20. The cap return section 40 returns

the unaligned pump/dosing pump caps C to the outside. That is, the

pump/dosing pump caps C, which are laid down on the lifter 201 , are

raised and returned through the cap return section 40.

The cap return section 40 is vertically mounted at an opposite

side of the cap supply section 30 with the cap sorting section 20

disposed therebetween. The cap return section 40 may be fixed to the

cap sorting section 20. The cap return section 40 may receive and

discharge the unaligned pump/dosing pump caps C that are transferred

on the conveyor belt 211 to the outside. To this end, the cap return

section 40 includes a receiving unit 401 and a return unit 403. An

opening 4011 is formed in an upper portion of the receiving unit 401.

The unaligned pump/dosing pump caps C fall down into the opening

4011. Such a method may be employed to receive the unaligned

pump/dosing pump caps C by using the receiving unit 401.

The return unit 403 communicates with the receiving unit 401.

Accordingly, the return unit 403 can return the unaligned pump/dosing

pump caps C downward. Although not shown in Fig. 1 , the return unit

403 may be connected to the cap supply section 30 to re-supply the

pump/dosing pump caps C to the cap sorting section 20.

The cap transfer section 10 aligns a plurality of pump/dosing

pump caps C side by side to discharge them to the outside through a

pipe chute 130. To this end, a lower portion of the pipe chute 130 is

opened. The cap transfer section 10 operates a transfer unit 110 in the

arrow direction to discharge the pump/dosing pump caps C that are

aligned side by side through the pipe chute 130. Accordingly, as shown

in the left side of Fig. 1 , the pump/dosing pump caps C can be aligned

side by side.

The above-described apparatus for sorting caps 100 enables the

pump/dosing pump caps C to be aligned side by side. Hereinafter,

functions and operations of constitutional components of the apparatus

for sorting caps 100 will be described in more detail with reference to

Figs. 2 to 16.

Fig. 2 schematically illustrates the state in which pump/dosing

pump caps C are raised by a pair of lifters 2011 and 2013.

The pump/dosing pump cap C includes a cap body C10 and a

suction pipe C20 connected to a lower portion of the cap body. The cap

body C10 and the suction pipe C20 are disposed in response to their

internal and external positions with respect to the liquid container when

they are actually combined with the container. When they are combined

with the liquid container, the cap body C10 is positioned outside the

container with the suction pipe C20 inside the container, so that the

pump/dosing pump cap C is divided as shown in Fig. 2.

The pump/dosing pump cap C sucks the liquid from below

through the suction pipe C20, and then discharges the liquid through the

outlet C1011 disposed at one side of the cap body C10. The cap body

C10 includes a head C100 and a container combining unit C110. The

outlet C1011 is disposed at one side of the cap body C10. When the

head C100 is depressed, the liquid is discharged through the outlet

C1011 due to its pumping operation. A large number of screw lines are

disposed on an inner wall of the container combining unit C110 and are

combined with the container.

As shown in Fig. 2, the first lifter 2011 hangs up and fixes a lower

portion of the cap body C10. The second lifter 2013 supports the

suction pipe C20. The pump/dosing pump cap C is slightly inclined to

be fixed to the lifters 2011 and 2013, so that the pump/dosing pump cap

C can be safely fixed. In particular, there exists a sharp step between

the cap body C10 and the suction pipe C20, so that a sufficient space for

supporting the lower portion of the cap body C10 by means of the first

lifter C2011 can be secured. As shown in Fig. 2, the first lifter 2011 and

the second lifter 2013 have a longer interval therebetween toward their

outsides, so that the pump/dosing pump cap C can be more safely fixed.

Fig. 3 illustrates an enlarged cap sorting section 20 of Fig. 1.

Referring to Fig. 3, the pump/dosing pump cap C is not shown for

simplicity of explanation. A pair of lifters 2011 and 2013 among a

plurality of lifters 201 align and raise pump/dosing pump caps C side by

side.

As shown in Fig. 3, the cap erection section 220 and the cap

removal section 240 are mounted on the casing 90. The cap erection

section 220 and the cap removal section 240 may be employed to align

or remove unaligned pump/dosing pump caps C from the cap sorting

section 20.

The cap erection section 220 includes a cap erection plate 2201

and a support 2203 for supporting the same. The support 2203 is

securely fixed to the casing 90. Accordingly, the cap erection section

220 is not moved and is securely fixed even when the cap erection plate

2201 collides with the pump/dosing pump cap C.

The cap erection section 220 is spaced apart from the lifter 201 in

order to prevent interference with the lifter 201. In addition, the cap

erection section 220 is mounted over a width direction (i.e., an X axis

direction) of the conveyor belt 211. Accordingly, all of the unaligned

pump/dosing pump caps C among the pump/dosing pump caps C

transferred by the lifters 201 can be correctly orientated. In particular,

the cap erection section 220 is inclined toward the upper portion of the

conveyor belt 211 , so that the pump/dosing pump caps C are effectively

and correctly orientated. An operation procedure of the cap erection

section 220 will be described in more detail with reference to Figs. 4 and

5.

The cap removal section 240 is mounted on an upper portion of

the cap erection section 220. The reason is as follows. The

pump/dosing pump caps C are first aligned so as to make a longitudinal

direction of the pump/dosing pump cap C to the same as a raising

direction of the conveyor belt 211. To this end, the cap erection section

220 is employed. The outlet is then hung on the lifter to preferably

remove the unaligned pump/dosing pump caps C using the cap removal

section 240. When the above-described procedures are sequentially

carried out to align the pump/dosing pump caps C, the pump/dosing

pump caps C can be more effectively aligned. Accordingly, the cap

erection section 220 is preferably disposed at a lower portion of the cap

removal section 240.

The cap removal section 240 operates in forward and backward

directions toward the conveyor belt 211 to strike the unaligned

pump/dosing pump caps C. The cap removal section 240 is spaced

apart from the lifters 201 in order to prevent interference with the lifters

201. In addition, the cap removal section 240 is disposed over the width

direction (i.e., an X axis direction) of the conveyor belt 211. Accordingly,

all of the unaligned pump/dosing pump caps C among pump/dosing

pump caps C transferred by the lifters 201 can be struck and fall down.

To this end, the cap removal section 240 includes a cylinder 2411 ,

a power transmission unit 2413, and a cap removal unit 2415. In

addition, the cap removal section 240 may further include a support 2417

for fixing the cylinder 2411 to the casing 90. The power transmission

unit 2413 is operated by oil or air inflowing from outside of the cylinder

2411. The power transmission unit 2413 is connected to the cylinder

2411 and operates in forward and backward directions. A plurality of

power transmission units 2413 enables the cap removal unit 2415 to

smoothly operate. The cap removal unit 2415 strikes the unaligned

pump/dosing pump caps C. A detailed structure of the above-described

cap removal section 240 can be easily understood by those skilled in the

art, so that a detailed description thereof will be omitted. An operation

procedure of the cap removal section 240 will be described in more detail

with reference to Figs. 6 to 8.

Figs. 4 and 5 illustrate sequential procedures for correctly

orientating pump/dosing pump caps C using the cap erection section 220.

Referring to Figs. 4 and 5, portions required for the explanation are

shown and the rest of the parts are omitted for simplicity of explanation.

The alignment procedures of the pump/dosing pump caps C shown in

Figs. 4 and 5 are exemplary, and the present invention is not limited

thereto. Accordingly, other methods may be employed to align the

pump/dosing pump caps C.

As shown in Fig. 4, motors 2110 are disposed on both sides of

the conveyor belt 211. The motors 2110 rotate in the arrow direction so

that the conveyor belt 211 operates in upward and downward directions

(i.e., the arrow directions). The pump/dosing pump caps C are correctly

aligned with the lifters 2011 and 2013 at upper and middle portions of Fig.

4, but the pump/dosing pump cap C at the lower portion of Fig. 4 is not

correctly aligned with the lifters 2011 and 2013. That is, as shown in the

lower portion of Fig. 4, the pump/dosing pump cap C may be laid down

on the first lifter 2011. In this case, the suction pipe C20 is protruded

forward, so that the suction pipe C20 needs to be manipulated for

correctly orienting the pump/dosing pump cap C. The fixed cap erection

section 220 is employed to correctly orient the pump/dosing pump cap C.

Meanwhile, the cap erection section 220 should not interfere with

the first lifter 2011. To this end, a distance d between the first lifter 2011

and the cap erection section 220 preferably ranges from 7 cm to 30 cm in

a direction vertical to the conveyor belt 211 as a reference. That is, the

distance d corresponds to the case in which the direction vertical to the

conveyor belt 211 is taken as a reference. The distance d is a value

that is calculated in consideration of the length of the suction pipe C20

that can be hung over the first lifter 2011 using the typical length of the

pump/dosing pump cap C as a reference. In this case, when the

distance d is less than 7cm, the cap erection section 220 is highly likely

to contact the first lifter 2011. In addition, when the distance d exceeds

30 cm, the laid pump/dosing pump cap C cannot be removed by the cap

erection section 220. The first lifter 2011 is exemplary in Fig. 4, and the

present invention may be applied to the second lifter 2013 in the same

way.

Fig. 5 illustrates a procedure of correctly orienting the

pump/dosing pump cap C by means of the cap erection section 220. As

shown in Fig. 5, the suction pipe C20 of the pump/dosing pump cap C is

hung below the cap erection section 220. In this case, the conveyor belt

211 continues rotating, so that the pump/dosing pump cap C rotates in

the arrow direction. Such a method can correctly orient the

pump/dosing pump cap C. The correctly oriented pump/dosing pump

cap C is hung on the first lifter 2011 to be raised or fall downward.

Although not shown in Fig. 5, a space is disposed in the lower portion of

the conveyor belt 211 so that the fallen pump/dosing pump cap C can be

recycled again.

Figs. 6 to 8 illustrate sequential procedures of removing the

pump/dosing pump cap C using the cap removal section 240. Referring

to Figs. 6 to 8, portions required for the explanation are shown and the

rest of the parts are omitted for simplicity of explanation. The procedure

of removing the pump/dosing pump cap C shown in Figs. 6 to 8 is only

exemplary, and the present invention is not limited thereto. Accordingly,

other methods may be employed to remove the pump/dosing pump cap

C.

As shown in Fig. 6, the cap removal section 240 enables the

pump/dosing pump cap C, in which the outlet C1011 thereof is hung on

the first lifter 2011 to be removed. Such a pump/dosing pump cap C

may have interference with the cap transfer section 10 (see Fig. 1) due to

an abnormal position at the top. Accordingly, the above-described

pump/dosing pump cap C can be removed in advance to prevent the

failure of the apparatus for sorting caps.

As shown in Fig. 6, the outlet C1011 of the pump/dosing pump

cap C is hung on the first lifter 2011 , so that the suction pipe C20 is

elongated and fixed downward from the second lifter 2013. Accordingly,

the suction pipe C20 disposed downward from the second lifter 2013 can

be struck to remove the pump/dosing pump cap C.

As shown in Fig. 7, the cap removal section 240 operates in

parallel with the second lifter 2013. That is, the cap removal unit 2415

moves in forward and backward directions in parallel with the second

lifter 2013. Accordingly, when the cap removal unit 2415 moves forward,

the suction pipe C20 simultaneously has a stress resulted from the cap

removal unit 2415 and a stress resulted from the second lifter 2013

supporting the suction pipe C20 in directions opposite to each other.

Accordingly, the pump/dosing pump cap C can be easily removed.

The cap removal section 240 does not always operate, but rather

it operates in forward and backward directions downward from the

second lifter 2013 in accordance with movements of the conveyor belt

211. When the cap removal section 240 otherwise operates, it also

strikes the correctly aligned pump/dosing pump cap C to be removed.

Accordingly, the cap removal section 240 moves forward only when the

cap removal section 240 faces downward from the second lifter 2013.

This timing can be matched by adjusting the rotational period of the

conveyor belt 211 and the operational period of the cap removal section

240. Details of the period adjustment can be easily understood by those

skilled in the art, so a detailed description thereof will be omitted.

Accordingly, in a case of the correctly aligned pump/dosing pump cap C,

the suction pipe C20 is not disposed downward from the second lifter

2013, so that the second lifter 2013 does not interfere with the

pump/dosing pump cap C even when the second lifter 2013 operates.

As shown in Fig. 8, the cap removal section 240 quickly moves

backward in the arrow direction while the pump/dosing pump cap C

rotates in the arrow direction. Such a method can remove the

pump/dosing pump cap C that is not correctly aligned. Since the

pump/dosing pump cap C instantaneously moves up into the air, it does

not interfere with another pump/dosing pump cap C moving upward and

falls downward. Such a method can remove the pump/dosing pump

cap C that is not correctly aligned.

Fig. 9 illustrates the cap transfer section 10 of Fig. 1 when seen

from a rear side of Fig. 1. Referring to Fig. 9, unnecessary portions are

omitted for simplicity of explanation. The shape of the cap transfer

section 10 of Fig. 9 is exemplary, but the present invention is not limited

thereto. Accordingly, various changes can be made to the shape of the

cap transfer section 10.

The cap transfer section 10 includes a transfer unit 110, a support

unit 120, and a pipe chute 130. The transfer unit 110 moves forward

toward the side of the pump/dosing pump cap C moving on and upward

from the conveyor belt 211 or moves backward from the side of the

pump/dosing pump cap C (i.e., in a thin arrow direction). The transfer

unit 110 has a cylinder so that it can operate by means of hydraulic

power or pneumatic power. The support unit 120 is spaced apart from

an upper portion of the cap sorting section 20 to fix the transfer unit 110.

The support unit 120 may be integrated with the casing 90 (shown in Fig.

1) as one body. The pipe chute 130 aligns a plurality of pump/dosing

pump caps C discharging from the transfer unit 110, and transfers them

to the outside in accordance with movements of the transfer unit 110.

The transfer unit 110 includes a pusher 1101 and a guide

member 1103. The pusher 1101 is mounted at one side of the transfer

unit 110. The guide member 1103 extends along the arranging direction

of the pump/dosing pump caps C. The guide member 1103 guides the

cap body C10 when the pusher 1101 operates.

The enlarged circle of Fig. 9 illustrates that the transfer unit 110

moves forward toward the pump/dosing pump cap C. The guide

member 1103 has a pair of guide units 1103a and 1103b, and the cap

body C10 is positioned in the space 1103s that is spaced apart between

the guide units 1103a and 1103b when the transfer unit 110 moves

forward. Accordingly, the guide units 1103a and 1103b enable the cap

body C10 to be safely fixed while the pusher 1101 operates to transfer

the pump/dosing pump cap C.

The pusher 1101 operates in the arranging direction of the cap

body C10 (i.e., in the thick arrow direction) to push the pump/dosing

pump cap C to the pipe chute 130. The pipe chute 130 is mounted

facing downward, so that the pump/dosing pump caps C can be safely

aligned and transferred.

As described above, after the pusher 1101 pushes the

pump/dosing pump caps C to the pipe chute 130, it returns to one side of

the transfer unit 110. The transfer unit 110 simultaneously moves

backward. Such a procedure may be repeatedly carried out to smoothly

transfer the pump/dosing pump caps C which are raised. A detailed

operational configuration of the transfer unit 110 can be easily

understood by those skilled in the art, so a detailed description thereof

will be omitted.

Figs. 10 and 11 illustrate a procedure of returning unaligned

pump/dosing pump caps C through the cap return section 40. The

procedure of returning the pump/dosing pump caps C shown in Figs. 10

and 11 is exemplary, and the present invention is not limited thereto.

As shown in Fig. 10, pump/dosing pump caps C that are correctly

aligned with the lifters 2011 and 2013 are raised while pump/dosing

pump caps C laying down between the adjacent lifters 2011 and 2013

are raised. The pump/dosing pump cap C laying on the first lifter 2011

is shown in Fig. 10, but it may be laid down on the second lifter 2013.

The cap transfer section only fixes the cap body of the

pump/dosing pump cap C on the upper portion of the first lifter 2011 and

transfers it to the outside (see Fig. 9). Accordingly, the cap transfer

section is not in contact with the pump/dosing pump cap C disposed at a

lower position. That is, the pump/dosing pump cap C is laid between

the lifters 2011 and 2013 so that it is not in contact with the cap transfer

section. Therefore, the pump/dosing pump cap C continues moving on

along the conveyor belt 211.

As shown in Fig. 11 , the pump/dosing pump cap C that continues

moving on along the conveyor belt 211 flicks off in the arrow direction

due to inertia. The flicked pump/dosing pump cap C is returned

downward through the cap return section 40. Such a procedure

enables the unaligned pump/dosing pump cap C to be effectively

removed.

Fig. 12 illustrates an enlarged cap supply section 30 of Fig. 1.

For simplicity of explanation, a casing surrounding the cap supply section

30 is not shown. The structure of the cap supply section 30 shown in

Fig. 12 is exemplary, and the present invention is not limited thereto.

Accordingly, other shapes may be applied to the structure of the cap

supply section 30.

The cap supply section 30 shown in Fig. 12 causes the cap

bodies of the pump/dosing pump caps C to face upward, and aligns the

pump/dosing pump caps C in the Y axis direction. Accordingly, it

supplies the aligned pump/dosing pump caps C to the cap sorting section

so that the pump/dosing pump caps C can be more effectively sorted.

The cap supply section 30 has equipment suitable for the same.

The cap supply section 30 includes a plurality of conveyor belts

301 and 303. The conveyor belt includes the first conveyor belt 301 and

the second conveyor belt 303. More conveyor belts may be mounted if

necessary. The first and second conveyor belts 301 and 303 are driven

by the respective motors 3011 and 3031. The second conveyor belt 303

is disposed below the front end 301 a of the first conveyor belt 301.

Accordingly, the pump/dosing pump caps C that have been transferred

on the first conveyor belt 301 can be continuously transferred on the

second conveyor belt 303. The second conveyor belt 303 is connected

to the conveyor belt of the cap sorting section to supply the pump/dosing

pump caps C to the cap sorting section.

The cap supply section 30 includes a first directional adjustment

member 321 and a second directional adjustment member 323. The

first directional adjustment member 321 is mounted at an end of the

upper guide plate 311 , and the second directional adjustment member

323 is mounted at an end of the lower guide plate 316. The first

directional adjustment member 321 switches the direction of the

pump/dosing pump cap C, and the second directional adjustment

member 323 guides the pump/dosing pump cap C. The first and

second directional adjustment members 321 and 323 will be described

later in detail with reference to Figs. 14 to 16.

The upper guide plate 311 disposed on the first conveyor belt 301

includes first guide plates 3111 and second guide plates 3113. The first

guide plates 3111 are disposed at central positions of the upper guide

plate 311 , and the second guide plates 3113 are disposed at both sides

thereof. In addition, the second guide plates 3113 are more protruded

toward the inflow of the pump/dosing pump caps C than are the first

guide plates 3111. Accordingly, the pump/dosing pump caps C that are

stuck in the first and second guide plates 3111 and 3113 cannot be laid

down in the X axis direction. Therefore, it is easy to switch the direction

so as to dispose the pump/dosing pump caps C in parallel with the Y axis

direction.

The cap dispersing section 313 is mounted at a front end of the

guide plates 311. The cap dispersing section 313 is mounted along the

arranging direction (i.e., the X axis direction) of the guide plates 311.

The cap dispersing section 313 disperses amassed pump/dosing pump

caps C to introduce the pump/dosing pump caps C to the guide plates

311.

The cap dispersing section 313 includes a rotational axis 3131

and a plurality of hooks 3133. The rotational axis 3131 is mounted

along the arranging direction (i.e., the X axis direction) of the guide plates

311. Although not shown in Fig. 12, the rotational axis 3131 is safely

fixed to the casing. The hooks 3133 are spaced apart from each other

and are mounted on the rotational axis 3131. The hooks 3133 extend in

a circumferential direction of the rotational axis 3131. The hooks 3133

can push the pump/dosing pump caps C in accordance with rotation of

the rotational axis 3131 shown in the arrow direction to disperse the

pump/dosing pump caps C. The rotational direction of the rotational

axis 3131 is the same as that of the first conveyor belt 301. Therefore,

the hooks push the pump/dosing pump caps C which move on along the

conveyor belt 301 in a direction opposite to the movement direction, so

that the pump/dosing pump caps C can be effectively dispersed.

As shown in Fig. 12, the hooks 3133 are alternately disposed at

upper and lower sides. That is, the adjacent hooks 3133 are disposed

in an angle to be different from each other. Accordingly, when a

pump/dosing pump cap C is hung at a position of the adjacent hooks

3133, the hooks 3133 may not operate together so that the pump/dosing

pump cap C can be disposed in parallel with the Y axis. In particular, as

shown in the enlarged circle of Fig. 12, the end 3133a of the hook 3133

where a concave portion 3133s is formed is bent in a direction opposite

to the rotational direction of the rotational axis 3131 , so that the

introduced pump/dosing pump caps C can be effectively pushed and

dispersed.

In addition, the hook 3133 is mounted to correspond to the guide

plate 3111 and is adjacent to the near position of the guide plate 3111 , so

that the hook 3133 passes the guide plate 3111 at the time of rotation.

When the guide plate 3111 passes the concave portion 3111s of the hook

3133, the hook 3133 should be smoothly rotated. Accordingly, a front

end 3111a of the guide plate 3111 is chamfered as a curved shape. As

a result, the hook 3133 does not hang on the guide plate 3111 but

smoothly rotates.

Fig. 13 illustrates a partial plan diagram of the cap supply section

30 shown in Fig. 12. Referring to Fig. 13, unnecessary portions are

omitted for explaining the cap dispersing section 313.

As shown in Fig. 13, hooks 3133 are mounted to correspond to

the respective guide plates 311. Since the hooks 3133 are not mounted

between the guide plates 311 , the pump/dosing pump caps C are

smoothly introduced between the guide plates 311. In particular, the

direction of the pump/dosing pump caps C can be switched to be in

parallel with the Y axis as the hooks 3133 rotate. That is, as shown in

the arrow direction, the pump/dosing pump caps C rotate. Accordingly,

the pump/dosing pump caps C are aligned with the direction in parallel

with the Y axis to be introduced between the guide plates 311. As

described above, the cap dispersing section 313 enables the

pump/dosing pump caps C to be dispersed. Therefore, the

pump/dosing pump caps C can be introduced side by side between the

guide plates 311.

Figs. 14 to 16 illustrate a sequential procedure of switching the

direction of the pump/dosing pump caps C and aligning them. The

procedure is exemplary, and the present invention is not limited thereto.

As shown in Fig. 14, since the first conveyor belt 301 moves

forward, the pump/dosing pump caps C stacked thereon also move

forward. The pump/dosing pump caps C do not fall downward but

continue to move even when the pump/dosing pump caps C reach near

the front end 301 of the first conveyor belt 301. That is, since the mass

of the cap body C10 is greater than the mass of the suction pipe C20 in

the pump/dosing pump cap C, the center of gravity is in the cap body

C10. Accordingly, the pump/dosing pump cap C continues to move

forward for a predetermined time even when the suction pipe C20 floats

up into the air.

As shown in Fig. 15, the pump/dosing pump cap C moves

forward along the inclined plane of the first directional adjustment

member 321. In this case, the suction pipe C20 is disposed on the

inclined plane 321a of the first directional adjustment member 321 , and

the cap body C10 floats up into the air. Since the center of gravity is in

the cap body C10, the pump/dosing pump cap C falls downward while

rotating in the clockwise direction (i.e., the arrow direction). As

described above, the first directional adjustment member 321 enables

the direction of the pump/dosing pump cap C moving with its suction pipe

C20 facing forward to be switched.

In contrast, since the pump/dosing pump cap C with its cap body

C10 facing forward has the center of gravity in the cap body C10, it does

not hang on the first directional adjustment member 321 and immediately

falls when it reaches the front end 301a of the first conveyor belt 301.

Since the first directional adjustment member 321 is spaced apart from

the first conveyor belt 301 by a sufficient interval, the pump/dosing pump

cap C with its cap body C10 facing forward can immediately fall

downward.

As shown in Fig. 16, the pump/dosing pump caps C, whose

direction is switched, are guided to the second conveyor belt 303 along

the inclined plane 323a of the second directional adjustment member

323. The second directional adjustment member 323 is mounted below

the front end 301a of the second directional adjustment member 301.

An inclined plane 323a is formed in the second directional adjustment

member 323 in a direction opposite to the direction of the inclined plane

321a of the first directional adjustment member 321. Therefore, the

pump/dosing pump caps can be safely guided to the second conveyor

belt 303.

As shown in Figs. 14 to 16, directions of the pump/dosing pump

caps C can be switched by the directional adjustment members 321 and

323, and then the pump/dosing pump caps C can be supplied to the cap

sorting section. Therefore, the efficiency of sorting the caps in the cap

sorting section is enhanced, so that about 120 pump/dosing pump caps

C can be sorted per minute.

Preferred embodiments of the present invention have been

disclosed herein and, although specific terms are employed, they are

used and are to be interpreted in a generic and descriptive sense only

and not for purpose of limitation. Accordingly, it will be understood by

those of ordinary skill in the art that various changes in form and details

may be made without departing from the spirit and scope of the present

invention as set forth in the following claims.
