Description:
Compacting device for compressing of material.

The present invention relates to an arrangement for a compactor intended for compressing materials consisting of a rotatably driven compactor roller carried on a support arm.

Previously disclosed compactors which function with a rotatably driven compactor roller carried on a support arm normally comprise only a single compactor roller, which brings a number of disadvantages such as reduced efficiency and oblique loadings.

The support arm in previously disclosed compactors is also so arranged as to extend either vertically or from a centrally located bearing component for the arm, which may lead to bearing, force and drive problems. The principal object of the present invention is accordingly, in the first instance, to make available an arrangement which solves the aforementioned problems, amongst others.

Said object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially in that at least two driven compactor rollers extending from a common rotating component rotatably mounted at the centre of a receiving vessel are carried by a support arm inclined from the edge of the vessel down towards the centre of the vessel, which support arm is capable of being driven and guided in a vertical sense along a vertically extending upright, in that the rotating component is formed by a disc which is carried by a rotating bearing, in that the disc carries a drive motor for driving at least one of the rollers, in that the rotating bearing is in the form of an hydraulic motor, and in that the support arm extends downwards at an angle from a bearing guided along the upright.

The invention is described below in the form of a number of illustrative embodiments, in conjunction with which reference is made to the accompanying drawings, in which:

Fig. 1 shows a side view in partially sectioned form of a first illustrative embodiment of a compactor;

Fig. 2 shows a top view of the compactor; Fig. 3 shows a side view in partially sectioned form of a second illustrative embodiment of a compactor;

Fig. 4 shows a top view of the compactor in accordance with the second example;

Fig. 5 shows a side view in partially sectioned form of a third illustrative embodiment of a compactor in its effective compacting position;

Fig. 6 shows a top view of this third illustrated compactor, and

Fig. 7 shows a side view of a part of a compactor in accordance with a fourth illustrative embodiment.

An arrangement 1 for a compactor 2 intended for compressing material, such as paper, wood, metal, textiles and plastic, etc., in conjunction with refuse collection or other operations in which it is wished to reduce the volume of material that is being handled, and which comprises a rotatably driven compactor roller 3 carried by a support arm 4, has the compactor roller 3 and support arm 4 that are present specially arranged in accordance with the present invention. More specifically, at least two compactor rollers 3 extending from a common rotatably mounted rotating component 5, which is situated at the centre 6 of a receiving vessel 7, are carried. The arrangement 1 also exhibits a support arrangement 8 for the rollers 3, which comprises a support arm 4 inclined from the outside of the edge 9 of the vessel in a direction 10 down towards the centre of the vessel, and which, in accordance with the invention, is capable of being driven and guided in a vertical 11, 12 sense along a vertically extending upright 13.

The upright 13 may consist of a vertical profile, for example a square tube, attached to a frame 14.

The aforementioned rotating component between the rollers 3 can be formed from a common disc 5 or a

similar frame component which is carried by a rotating bearing 15 at its upper end part 16 and central area 17. The rotating bearing is preferably in the form of an hydraulic motor 15.

The aforementioned disc 5 is also intended to carry drive motors 18 for the rollers 3, preferably with one motor 18 for each roller 3.

A sleeve 21 projecting laterally 19, 20 and preferably in a horizontal direction from the disc 5 appropriately forms an attachment component for carrying the motor, namely in the form of a bearing for a compactor roller 3 enclosing same with a part 22 at its inward-facing end 3A.

The motor 18 for driving the roller 3 may consist of an hydraulic motor with its hydraulic drive lines accommodated in such a way as to extend through the support arm 4 for the rollers, the rotating bearing 15 and the disc 5. The motor shaft 23, which projects laterally 19, 20 from the respective motor 18, is connected to a roller frame part 24 to enable it, via same, to transmit rotation to the roller 3.

The aforementioned support arm 4, which is preferably common for all the rollers 3, is arranged at an angle X in relation to the upright 13 such that it extends inclined at an angle downwards 10 towards the centre 6 of the container from a bearing 25 guided as it moves along the upright 13. The bearing preferably consists of a sliding bearing, for instance a sleeve 25 around the upright with an internal bearing, preferably made of robalon.

The angle X for the support arm 4 can be selected according to the power needed and the space required, for example according to the height H or the width V, etc., of the vessel. A suitable value for the angle X may be between approx. 45° and 60° in order to obtain the normal force effect.

A jack 26 may finally be arranged so that it acts between the support arm 4 and/or the bearing sleeve 25 and a part of the frame 14. The jack may consist, for example, of an hydraulically driven piston cylinder attached via the articulated links 27, 28. Actuation of the jack 26 in either

direction 29, 30 respectively causes raising and lowering of the support arm 4 and the compactor rollers 3 attached thereto and rotatably driven in optional directions 31, 32.

Illustrated in Figs. 3-4 is an alternative embodiment of a compactor 102, which differs from the previously described compactor 2 only in respect of the design and extent of the support arm. More specifically the support arm 104, which carries pairs of rollers 103 for compacting material in a compaction vessel 107 intended for that purpose, exhibits an upper horizontal support arm part 104A and a lower downward-inclined support arm part 104B attached to the outer end 104A' of the aforementioned upper support arm at the upper support arm part 104B' of the inclined support arm part, at the lower end of which a pivotally mounted frame disc 105 is carried on a rotating bearing 115, and on which the rollers 103 are mounted so as to be capable of being driven.

The angle of inclination CX of the said lower and outer support arm part 104B may be less than prevously, and the said embodiment permits a lower structural height for the compactor 102.

The function of the invention can be appreciated from the foregoing and from the schematic drawings. Actuation of the jack 26 in either direction 11 and 12 causes the arm 4, 104 to move upwards or downwards in the compactor vessel 7 for the purpose of actuating the rollers 3 in the desired direction to raise them from the vessel 7 when it is to be replaced or emptied once the contents of the vessel 3 are fully compacted, or to assist the rollers to be pressed down whilst they are being driven in the intended direction of rotation 31, 32 by means of the roller drive motors 18 and in the intended direction of driving 33, 34 by means of any drive imparted to the rotating bearing 15, depending on, amongst other things, the characteristics and the nature of the intended material to be compacted. The compactor 202 illustrated in Figs.

5 and 6 differs from the examples described above in respect of the motor carrier, the arm bearing 208 and the pattern of movement

of the rollers. In this case a drive motor 218 is carried by a bracket 250 projecting laterally from a disc 205 of the kind referred to intended for carrying the compaction rollers 203 in an upwardly open compaction vessel 207 of the kind referred to. Said bracket 250 consists preferably of a U-section yoke which extends across the disc 205 and into an opening 251 in the disc 205. In this way, a single motor 218 is adequate to drive the two compaction rollers 203.

The rollers 203 are carried in this case by the obliquely downward-inclined arm 204, which is transformed at its extremity into an outer arm 252, which in turn is inclined downwards around a vertical rotating bearing 215, which arm supports the disc 205. The rollers 203 project inwards beyond the vertical centre line 206 of the vessel and said rotating bearing 215, i.e. the disc 205, which carries the rollers, each projecting in its own direction from the disc 205, is displaced laterally for a certain distance A from said centre line 206.

The bearing 208 for the arm 204 consists of a ball bearing, preferably of the ball screw type, wherein the upright 213 is rotatably mounted about a vertical shaft 253.

In other respects this compactor functions like the compactors previously described above. The lower part of a compactor 302 illustrated in Fig. 7 represents a different roller arrangement with its associated means of carrying the drive motor and driving the rollers, although it can be stated that this compactor 302 in other respects is of a similar kind to those described above and illustrated in the drawings. Pairs of rollers 303, 350, which have different diameters D and d, are in this case carried by a disc 305 capable of rotating about a vertical axis of rotation 306, and are caused to rotate about said axis of rotation 306 while compacting material in an enclosing vessel intended for that purpose. Only one of the rollers 303, 350 is driven by a drive motor 318 and caused to rotate in the desired direction of rotation 331, 332, in conjunction with which the motor 318 is

carried by a bracket 352 situated inside said driven roller 303 and attached to the disc 305. The motor 318 has a single shaft and is attached via its shaft 353 to a roller end wall 354 attached to the outer end 303A of the roller. The roller 350, which exhibits the smaller diameter d, and which is so arranged as to function as a support roller for the larger roller 303, is carried by a horizontal bearing shaft 351 at its respective ends 351A, 351B on the shaft 351 and at the disc 305. A bearing 355 is so arranged as to connect the shaft 351 and a roller end wall 356 with one another. The axes of rotation 357 and 358 for the respective rollers 303 and 350 are situated at different levels, i.e. the axis of rotation 358 for the small roller 350 is situated at the lower level. The envelope surfaces 303B and 350B for the rollers 303 and 350 are situated on a common level I on the lower part 303C and 350C of the respective rollers.

A top-mounted motor 359 and a swivel 360 drive a vertical drive shaft 361 or other movement transmission component rigidly attached to an outer arm 362 extending downwards at an angle, which is rigidly attached to the disc 305 that carries the rollers 303, 350. The rollers 303, 350 are preferably mounted in such a way as to slide on robolon or a similar bearing material 363 and 364 at the respective ends 303D and 350D of the rollers facing in towards the disc 305. In this case, too, the disc 305 is displaced laterally outwards from the axis of rotation 306 for the arm 362, which in turn is carried by a downward-inclined raisable upper arm 304. With the present embodiment of the rollers, it is possible to make the larger roller 303 much larger than previously, thereby improving the effect of compression. This also reduces the risk of the roller 303 not taking hold of the material intended to be compacted by it, and of the small roller 350 not cleaning at the centre of the container.

The invention is not restricted to the illustrative embodiments described above and illustrated in the drawings, but may be varied within the scope of the Patent Claims without departing from the idea of invention.
