DESCRIPTION

GARMENT STITCHED BAG BASE JOINING MACHINE

The Related Art

The invention relates to garment stitched bag base joining machines for joining of the base parts of base-type carrying and storage bags made of different materials with the body in a quick and rapid manner, and for reducing the rate of wastage by standardizing the production.

The Prior Art

Nowadays, bag embodiments are used which are formed of a body with a base on the lower part thereof for shopping and for other purposes. In the patent document No. 2012/02108, entitled "production method of ultrasonic welded bag made of Pp and pe fabric and the bag produced according to this method", a bag embodiment with a bellows-type base and the production method thereof is described. Said invention relates to a bag for the storage and transport of post-sale products in the retail sector (clothing, shoes, food, etc.), made of polypropylene (PP), polyethylene (PE), laminated and nonlaminated fabrics, and via ultrasonic welding without using stitches in a quick manner, and the production method of said bag.

The production method exemplified in the prior art can only be used for fabrics made of a certain type of materials, and also made manually as in other embodiments. For this reason, the quality of the bag directly varies with the skill of the workers. Therefore, standardization cannot be achieved in production and accordingly the rate of wastage is high. The absence of any automation increases production time and thus increases production costs.

As a result, the need for garment stitched bag base joining machines joining of the base parts of base-type shopping and storage bags made of different materials with the body in a quick and rapid manner, and reducing the rate of wastage by standardizing the production, and the inadequacy of the prior art solutions about the subject have necessitated an improvement in the related technical field.

Purpose of the Invention

The invention relates to a bag base joining machine, which meets the above said requirements, eliminates all of the drawbacks, and brings some additional advantages. The main purpose of the bag base joining machine according to the invention is to adjust the sizes of base-type bags and cut the bags accordingly, and then following secondary operations like bending the bag opening and adding a holder, fitting the body of the bag into moulds and thus allowing their joining by means of a garment sewing machine that can move around the mould. The mould system provides standardization of each bag manufactured and also reduces rate of wastage. In addition, the error rate is also reduced because the human effect is also eliminated. In addition, with the motion system, the sewing machine moves rapidly in the direction of the determined route and increases the manufacturing speed considerably. This reduces the cost of production by reducing the overall manufacturing time.

Another purpose of the invention is to ensure mounting of a plurality of moulds, in which the bag body is fitted, on a movable table, and ensure automatic positioning thereof at the same level with the sewing machine. In this way, automation is allowed for serial production.

Another purpose of the invention is to ensure quick removal of the base-stitched bags from the mould, by means of the robotic arm mechanism. This allows rapid emptying of the mould and making it ready for the next operation.

Another purpose of the invention is to check whether the mould is at the correct position or not and whether a bag is present on the mould or not, by means of sensors placed at the same level with the sewing machine. By means of this characteristic of the sensors, the error ratio is reduced and possible malfunctions are eliminated.

In order to achieve the above said purposes in the most general sense, garment stitched bag base joining machines are developed for joining of the base parts of base-type shopping and storage bags made of different materials with the body in a quick and rapid manner, and for reducing the rate of wastage by standardizing the production. The developed joining machine comprises: a body, a garment-type sewing machine, at least one mould, in which the bag body is fitted, and which allows the base part to be fitted in a suitable position, at least one edge joining apparatus allowing the bag body to be joined with the edges of the base part, at least one motion mechanism allowing all the edges to be stitched by moving the sewing machine around the mould, and at least one control panel ensuring control of the sewing machine, joining apparatus, and motion mechanism.

The structural and characteristic features of the invention and all of its advantages shall be understood better with the figures and the detailed description given below in reference to the figures, and therefore, the assessment should be made by taking into account the said figures and detailed explanations.

Detailed Description of the Invention

A bag base joining machine (10) for joining of the base parts of base-type carrying, shopping, and storage bags made of different materials with the bag body in a quick and rapid manner, and for reducing the rate of wastage by standardizing the production, and it basically comprises: a garment-type sewing machine (20) positioned on a body (1 1 ), at least one mould (40), in which the bag body is fitted, and which allows the base part to be fitted in a suitable position, at least one edge joining apparatus (21 ) allowing the bag body to be joined with the edges of the base part, at least one motion mechanism (30) allowing all the edges to be stitched by moving the sewing machine (20) around the mould, and at least one control panel (70) ensuring control of the sewing machine (20), joining apparatus (21 ), and motion mechanism (30).

Figures 1 , 2, 3 and 4 are perspective, side, and rear views, respectively, of the joining machine (10) according to the invention. The motion mechanism (30) found at the upper part of the body (1 1 ) that carries and supports other components is directly connected to the sewing machine (20), and ensure the movement thereof in three axes, which are the horizontal axis (x), depth axis (z), and vertical axis (y). The joining apparatus (21 ) is connected under the sewing machine (20) and moves together with the sewing machine (20) to perform edge joining before sewing. In a preferred embodiment, a plurality of moulds (40) are found, and they are fitted on the movable table (50) which allows positioning to and removal from the sewing area. The movable table (50) rotates about the axis of the rotary shaft (52) mounted on the floor with the aid of the plate drive component (51 ). As shown in FIG. 1 , the movable table (50), which is rotating, successively carries the moulds (40) arranged around thereof to the sewing area. The drive component (51 ) works with the commands coming from the control panel (70) and ensures automation. Preferably, sensor (22) or sensors (22) positioned at the same level with the sewing machine (20) are used for detecting the position of the moulds (40) and/or sending information to the control panel (70) by checking whether the bag is present or not.

The robotic mechanism (60) ensuring moving of the stitched bag away from said moulds (40) is preferably positioned close to the rotating table (50) and directed by the control panel (70). Upon removal of the stitched bags from the moulds (40) via the robotic mechanism (60), the moulds (40) go idle and proceed to receive the next bag parts to be stitched/sewn. Figures 5a and 5b show the close-up perspective and close-up rear views, respectively, of the motion mechanism (30) found on the joining machine (10). The motion mechanism (30) basically comprises: at least one horizontal axis slide (32) that bears the motion of the sewing machine (20) on the horizontal axis (x), at least one horizontal axis drive component (33) allowing movement of the sewing machine (20) in the horizontal axis (x), at least one depth axis slide (34) bearing the depth axis (z) movement of the sewing machine (20), and at least one depth axis drive component (35) allowing movement of the sewing machine (20) in the depth axis (z). The connection of the sewing machine (20) to the horizontal axis slide (32) is ensured by the sewing machine plate (31 ). The movement mechanism (30) is thus positioned on the movement plate (36). The movement of the movement plate (36) in the vertical axis (y) is carried out by the vertical motion drive component (37).

FIG. 6 shows a perspective view of the mould (40) found in the joining machine (10). In the most general embodiment of the mould (40); at least one mould foot (41 ) on which the mould stands, and at least one mould connecting plate (42) for mounting of the mould foot (41 ) to the movable table (50) or another surface. As can be seen from FIG. 6, in the preferred embodiment, the mould (40) stands on two reciprocal mould feet (41 ), and it is connected to the movable table (50) by means of the mould connecting plate (4). The adjusting members (43) positioned on the mould feet (41 ) adjust the position of the bag body on the mould (40) with respect to the size thereof. A plurality of adjustment slots (44) allowing the adjustment piece (43) to be positioned at different distances on the mould foot (41 ) form the basis for the adjustment work. The lifting bar (45) positioned below the mould (40) ensures lifting of the stitched bag from the moulds (40), by means of the pusher tips (48). The drive required for this purpose is provided by the lifting piston (53), which is controlled by the control panel (70) and shown in Figs. 2 and 3. The lifting bar (45) lifted by the lifting piston (53) pushes the stitched bag upward by passing through the lifting slot (47) formed on the mould (40).

FIG. 7 shows a perspective view of the robotic mechanism (60) found in the joining machine (10). The robotic mechanism (60), comprises, in its most general form: a robotic mechanism body (61 ) which holds together and supports all the components thereof, at least one holder (63) with movable jaws (69) grasping the bag, at least one robotic arm (62) to which the holder (63) is connected, and which ensures the bidirectional movement thereof, and at least one robotic arm drive component (64) providing the robotic arm (62) with the bi-directional movement. In a preferred embodiment, the robotic mechanism (60) also comprises: at least one robotic arm holder (65) to which the robotic arm (62) is attached, at least one horizontal motion slide (66) bearing the horizontal plane movement of the robotic arm holder (65), and at least one horizontal motion drive component (67) allowing the movement of the robotic arm holder (65) in the horizontal plane. Thus, the bag lifted by the robotic arm (62) can also be moved horizontally. The bags released from the robotic mechanism (60) can be transferred to the collection area via the shifting plate (68).

Operation: First of all, the operator, who brings the adjustment piece (43) to the appropriate adjustment slot (44) on the mould foot (41 ) with respect to the bag size, fits the bag body into the mould (40) and positions the base part thereon. Then, from the control panel (70), the movable table (50) is rotated by means of the table drive component (51 ) to advance the mould (40) on which the bag parts are fitted to the same level with the sewing machine (20). Meanwhile, the sensors (22) determine the position and check whether the bag body is fitted or not and inform the control panel (70). If no problem is detected, then the motion mechanism (30) controlled by the control panel (70) is brought down by means of the vertical motion drive component (37). While the edge joining apparatus (21 ) located around the mould (40) joins the edges of the bag parts, the sewing machine (20) performs stitching operation. The edge joining apparatus (21 ) moving around the mould (40) by means of the motion mechanism (30) and the sewing machine (20) complete the joining operation and then are lifted by means of the vertical motion drive component (37). Afterwards, the mould (40) on which the stitched bag is found is moved on the movable table (50) via the table drive component (51 ) towards the robotic mechanism (60) connected to the control panel (70). Here, the lifting bar (45), which is pushed up by the lifting piston (53), passes through the lifting slot (47) and lifts the bag upwards on the base. At this moment, the robotic arm (62) moving downward holds the bag from the base by means of the holder (63) and is then lifted by means of the robotic arm drive component (64). The holding slot (46) formed on the lifting bar (45) allows the holder (63) to grasp the bag easily without applying pressure on the lifting bar (45). The robotic arm holder (65) is also moved forward at the same moment or sequentially on the horizontal motion slide (66), by means of the horizontal motion drive component (67). When it reaches the shifting plate (68), the holder (63) opens and releases the bag. The bag falling onto the shifting plate (68) reaches its destination by sliding. This cycle continues in this manner and the moulds (40) emptied by the robotic mechanism (60) are advanced towards the operator to be reloaded.
