Description

Technical Field

[0001] The invention relates to the technical field of fabric stacking, and in particular to a stacking machine for automobile leather cut pieces. Background Art

[0002] When processing fabrics, multiple sheets of fabrics need to be stacked together, and then the multi-layer fabrics are cut into the required shape through cutting equipment. If there are wrinkles in the stacked fabrics, this will cause the shape of the fabric after cutting to be different from the required fabric shape, thus causing product defects. At the same time, automotive leather itself is a relatively thin fabric.

[0003] In the prior art, the publication number is CN209906039U, and the name is leather cutting and stacking machine. This equipment can realize two displacement modes: lateral movement of the mechanical gripper and longitudinal displacement of the lifting platform. By controlling the mechanical gripper to grab and displace the leather, the stacking of leather pieces can be faster and more accurate. At the same time, this device can set the displacement of the lifting platform to descend regularly according to the different thicknesses of the leather, which can effectively avoid drift and dislocation of leather pieces during stacking due to excessive displacement of the lifting platform. Although this equipment can stack multiple layers of leather pieces by grabbing and displacing, the overall movement process is slow. This is mainly because the stacked leather is a heavier material. Therefore, it is necessary to use a robot gripping method for stacking. And the leather conveying of this equipment also adopts the fabric cutting machine in the prior art for layered conveying.

[0004] As for automobile leather, which is mainly used for automobile seats, it is thin and breathable, similar to fabric material. If the above device is used for palletizing, it will take a long time, which is not conducive to the rapid processing of the equipment.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment: The present invention provides a palletizing machine for cutting and stacking automobile leather pieces, such as Figure 1-4As shown, it includes a lifting mechanism 1, a placement table 2, a leather conveying mechanism 3, a cutting mechanism 4, a horizontal moving mechanism 5, a pressing mechanism 6, a lateral blowing mechanism 7, two longitudinal blowing mechanisms 8, two synchronous turning mechanisms 9 and an air supply mechanism 11. The leather conveying mechanism 3 can be horizontally moved on the placement table 2 through a horizontal moving mechanism 5, and the horizontal moving mechanism 5 is fixedly installed on the placement table 2. A feeding port 3a is provided on one side of the leather conveying mechanism 3, and a discharging port 3b is provided on the other side of the leather conveying mechanism 3. The leather conveying mechanism 3 is used to press and convey the leather fabric 10. The cutting mechanism 4 is fixedly installed on the leather conveying mechanism 3. The cutting mechanism 4 is used to After the movement is completed, the leather fabric 10 on the discharge port 3b is cut. When the leather fabric 10 needs to be cut and stacked, the leather conveying mechanism 3 presses the leather fabric 10, and then the horizontal moving mechanism 5 drives the leather conveying mechanism 3 to move to the right. The leather conveying mechanism 3 presses the leather fabric 10, so that the leather fabric 10 can be suspended and covered on the leather fabric 10 of the next layer. Then, the leather conveying mechanism 3 is driven to reset to the left by the horizontal moving mechanism 5. During the reset process, the leather conveying mechanism 3 continuously outputs the leather fabric 10, so that the leather fabric 10 discharged along the leather conveying mechanism 3 will be placed on the lower layer of leather fabric 10. In the process of the leather fabric 10 being placed, the leather fabric 10 will be wrinkled. At this time, the following structure is needed to solve the wrinkles and ensure the flatness of the placement. The lifting mechanism 1 is located on the outside of the placement table 2. The lifting mechanism 1 is used to drive the horizontal blowing mechanism 7 and the longitudinal blowing mechanism 8 to perform vertical lifting and lowering movements, wherein the placement table 2 located on the outside will not collide with the leather conveying mechanism 3 during the movement. The pressing mechanism 6 is fixedly installed on the lifting seat of the lifting mechanism 1, and the pressing mechanism 6 is used to press the middle part of the leather fabric 10. The air supply mechanism 11 is fixedly installed on the pressing mechanism 6, and the air supply mechanism 11 is used to provide high-pressure gas to the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8. The two transverse blowing mechanisms 7 are located on the two sides of the pressing mechanism 6 that are symmetrical to each other, and the two longitudinal blowing mechanisms 8 are located on the other two sides of the pressing mechanism 6 that are symmetrical to each other, and the two transverse blowing mechanisms 7 and the two longitudinal blowing mechanisms 8 are both rotatably connected with the synchronous flipping mechanism 9, and the synchronous flipping mechanism 9 is fixedly installed on the lifting mechanism 1, and the synchronous flipping mechanism 9 is used to drive the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 to rotate and tilt along the vertical downward jet upward to blow. When the leather fabric 10 needs to be flattened, the pressing mechanism 6 is first pushed downward by the lifting mechanism 1, so that the pressing mechanism 6 first presses the middle part of the leather fabric 10, and then air is supplied by the air supply mechanism 11, and then the horizontal blowing mechanism 7 and the longitudinal blowing mechanism 8 are driven to flip by the synchronous flipping mechanism 9, so that air is blown outward from the center, and the leather fabric 10 that is blown will be flattened under the push of the airflow.

[0034] If the air supply mechanism 11 is started after the leather fabric 10 is compressed, and finally the synchronous flip mechanism 9 is used for rotational driving, the whole process will take a long time, and the horizontal blowing mechanism 7 and the longitudinal blowing mechanism 8 only change the blowing direction of the airflow by rotating. In this way, the air blown at the end cannot push the leather fabric 10 to move. In order to solve the above problem, Figure 5-7 As shown, the pressing mechanism 6 includes a telescopic tube 6a, a bottom plate 6b and an air duct 6c, the air duct 6c is fixedly installed on the lifting mechanism 1, the telescopic tube 6a is fixedly installed at the bottom of the air duct 6c, the bottom plate 6b is fixedly installed at the bottom of the telescopic tube 6a, the bottom plate 6b is transmission-connected with a synchronous flipping mechanism 9, and the synchronous flipping mechanism 9 is fixedly installed at the upper part of the telescopic tube 6a. When the bottom plate 6b is squeezed with the leather fabric 10, the lifting mechanism 1 will continue to move downward, and since the bottom plate 6b cannot continue to move downward, the telescopic tube 6a will be compressed, causing the synchronous flipping mechanism 9 to move downward, that is, during the change process, the synchronous flipping mechanism 9 will drive the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 to rotate and spray, and at the same time, the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 will also move downward, which can make the gas ejected by the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 change in two directions, that is, an arc-shaped change, to ensure that the gas at the last blowing point of the transverse blowing mechanism 7 can push the leather fabric 10 to move. In order to solve the problem of long waiting time caused by the slow startup process of the air supply mechanism 11, the air supply mechanism 11 includes an annular air pipe 11a, a sealed pipe 11b, a baffle ring 11c and a telescopic pipe 11d. The sealed pipe 11b is sleeved on the outer edge of the air guide pipe 6c, and the annular air pipe 11a is sleeved on the outer edge of the sealed pipe 11b. The multiple annular air pipes 11a are upwardly provided with multiple air pipes connected to the sealed pipe 11b. The air pipes are connected to the sealed pipe 11d. An air inlet 11b1 is formed between the air guide tube 6c and the air outlet 6c1. The retaining ring 11c is fixedly installed on the outer edge of the air guide tube 6c. When the retaining ring 11c contacts the top of the sealed tube 11b, the air outlet 6c1 is connected to the air inlet 11b1. The bottom of the telescopic tube 11d is fixedly installed on the bottom plate 6b. The top of the telescopic tube 11d is fixedly connected to the annular air pipe 11a. The top of the air guide tube 6c is connected to the air supply equipment. Before the bottom plate 6b contacts the leather material 10, the bottom plate 6b descends, driving the synchronous flipping mechanism 9 and the annular air tube 11a to descend synchronously; the telescopic tube 11d supports the annular air tube 11a in mid-air, thereby ensuring the position of the annular air tube 11a.

[0035] After the bottom plate 6b contacts the leather fabric 10, the lifting mechanism 1 drives the air guide tube 6c to continue to descend, the telescopic tube 6a is compressed, and the synchronous flip mechanism 9 drives the horizontal blowing mechanism 7 and the longitudinal blowing mechanism 8 to rotate. At the same time, the air inlet 11b1 docks with the air outlet 6c1, and the retaining ring 11c contacts the top of the sealed tube 11b; that is, in the initial rotation process, the air outlet 6c1 quickly docks with the air inlet 11b1, saving the long waiting time caused by the slow start-up process of the air supply mechanism 11. Among them, through the sealing effect of the sealed tube 11b, the air supply device can maintain continuous air supply to the air guide tube 6c, and can be quickly started after the air outlet 6c1 docks with the air inlet 11b1.

[0036] After the retaining ring 11c contacts the top of the sealed tube 11b, the air guide tube 6c continues to descend, the telescopic tube 11d is compressed, and the synchronous flip mechanism 9 drives the lateral blowing mechanism 7 and the longitudinal blowing mechanism 8 to continue to rotate. After the bottom of the bottom plate 6b contacts the leather fabric 10, as the bottom plate 6b continues to descend, the lateral blowing mechanism 7 and the longitudinal blowing mechanism 8 can continue to rotate.

[0037] Since the leather material 10 is continuously stacked and thickened, the movement of the annular air tube 11a will not be affected, but the rotation working process of the synchronous flip mechanism 9 is related to the movement amplitude of the telescopic tube 6a. In order to reduce the influence of thickness on the movement amplitude, the synchronous flip mechanism 9 includes a mounting frame 9e, two rotating shafts 9a, two rotating seats 9b, two transmission rods 9c and two hinged rods 9d. The mounting frame 9e is fixedly mounted on the upper outer edge of the telescopic tube 6a, the rotating shaft 9a is fixedly connected to the longitudinal blowing mechanism 8, the two rotating seats 9b are respectively fixedly mounted on both sides of the mounting frame 9e, the rotating shaft 9a is rotatably connected to the rotating seat 9b, one end of the transmission rod 9c is fixedly connected to the rotating shaft 9a, the other end of the transmission rod 9c is hinged to the top of the hinged rod 9d, and the other end of the hinged rod 9d is hinged to the bottom plate 6b. When the bottom plate 6b cannot move, the mounting frame 9e will continue to drop, so that the hinged rod 9d can push the transmission rod 9c to rotate, that is, drive the longitudinal blowing mechanism 8 to change its angle. The longitudinal blowing mechanism 8 is driven to rotate by the transmission rod 9c and the hinge rod 9d. Fig. 9 As shown, after the longitudinal blowing mechanism 8 is rotated to the flipped state, even if it continues to descend or rises slightly, the influence on the rotation angle of the longitudinal blowing mechanism 8 is not significant, that is, the influence of the thickness on the movement amplitude is reduced.

[0038] Since the transverse blowing mechanism 7 is located above the longitudinal blowing mechanism 8, and the spacing between the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 should not be too large, the transverse blowing mechanism 7 needs to move synchronously with the longitudinal blowing mechanism 8, reducing the spacing setting between the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 to avoid collision between the longitudinal blowing mechanism 8 and the transverse blowing mechanism 7 during the upward rotation of the longitudinal blowing mechanism 8. The synchronous flipping mechanism 9 also includes two sets of transmission mechanisms, which are respectively fixedly installed on both sides of the mounting frame 9e. Each set of transmission mechanisms includes a bevel gear 1 9f, a bevel gear 2 9h, a driving shaft 9k and a driven shaft 9s. The bevel gear 1 9f is fixedly installed on one end of the rotating shaft 9a, and the bevel gear 2 9h is fixedly installed on the driving shaft 9k. The bevel gear 1 9f is meshed with the bevel gear 2 9h. The driving shaft 9k and the driven shaft 9s are both rotatably installed on the mounting frame 9e. The driving shaft 9k is connected to the driven shaft 9s through a sprocket set. The transverse blowing mechanism 7 is fixedly connected to the driven shaft 9s. When the longitudinal blowing mechanism 8 rotates, the rotating shaft 9a will rotate synchronously, and the rotating shaft 9a will drive the driving shaft 9k to rotate through the bevel gear 1 9f and the bevel gear 2 9h, and the driving shaft 9k will drive the driven shaft 9s to rotate through the action of the sprocket group, that is, the synchronous rotation of the transverse blowing mechanism 7 is realized. That is, the gap between the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 can be reduced, ensuring that when blowing, the blowing effect is reduced due to the increase in the height of the transverse blowing mechanism 7.

[0039] like Figure 4 As shown, the pressing mechanism 6 further includes four airflow ducts 11e, one end of the four airflow ducts 11e is respectively connected to the two transverse blowing mechanisms 7 and the two longitudinal blowing mechanisms 8, and the other end of the four airflow ducts 11e is connected to the annular air pipe 11a. The gas discharged outward along the annular air pipe 11a will be transported along the airflow ducts 11e and finally enter the interior of the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8, and then ejected outward along the interior of the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8.

[0040] In order to make the airflow diffuse and spray outward uniformly after entering the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8, for this purpose, Fig.11 As shown, a plurality of inclined partitions 7a which are obliquely and staggeredly distributed are arranged inside the transverse blowing mechanism 7. Through the action of the plurality of inclined partitions 7a, the gas entering the transverse blowing mechanism 7 can be blocked and dispersed, so that the gas can be sprayed out more evenly along the bottom of the transverse blowing mechanism 7. The transverse blowing mechanism 7 has the same structure as the longitudinal blowing mechanism 8.

[0041] like Figure 5As shown, a square mounting plate 6d is fixedly arranged on the outer edge of the air guide tube 6c, and the square mounting plate 6d is fixedly connected to the lifting mechanism 1 by screws. Since the lengths of the lateral blowing mechanism 7 and the longitudinal blowing mechanism 8 are different, the working directions of the lateral blowing mechanism 7 and the longitudinal blowing mechanism 8 can be changed by removing the screws and rotating the square mounting plate 6d by 90 degrees, so that the stronger airflow ejected by the longitudinal blowing mechanism 8 can change the blowing direction according to the fabric.

[0042] like Figure 3 As shown, a horizontal moving mechanism 12 is fixedly provided at the bottom of the lifting mechanism 1, and the horizontal moving mechanism 12 is fixedly installed on the ground. Since the length of the leather fabric 10 will change, when the length of the leather fabric 10 changes, its center position will change. Therefore, the horizontal moving mechanism 12 is used to adjust and change its moving position, so that the center position of the bottom plate 6b pressed can be changed.

[0043] like Figure 2 As shown, the lifting mechanism 1 includes a mounting frame 1a, a crossbeam 1b and a screw slide 1c. The mounting frame 1a is fixedly mounted on the displacement seat of the horizontal moving mechanism 12, the screw slide 1c is fixedly mounted on the mounting frame 1a, the crossbeam 1b is fixedly mounted on the displacement seat of the screw slide 1c, and the square mounting plate 6d is fixedly mounted on the crossbeam 1b. By controlling the screw slide 1c to work, the crossbeam 1b can drive the square mounting plate 6d to perform vertical lifting movement.

[0044] When in use, the leather conveying mechanism 3 presses the leather fabric 10, and then the horizontal moving mechanism 5 drives the leather conveying mechanism 3 to move rightward. The leather conveying mechanism 3 presses the leather fabric 10, so that the leather fabric 10 can be suspended and covered on the leather fabric 10 of the next layer. Then, the leather conveying mechanism 3 is driven to reset to the left by the horizontal moving mechanism 5. During the reset process, the leather conveying mechanism 3 continuously outputs the leather fabric 10, so that the leather fabric 10 discharged along the leather conveying mechanism 3 is placed on the leather fabric 10 of the next layer. In the process of placing the leather fabric 10, the leather fabric 10 will be wrinkled.

[0045] Then the bottom plate 6b is driven downward by the lifting mechanism 1. Before the bottom plate 6b contacts the leather fabric 10, the descent of the bottom plate 6b will drive the synchronous flipping mechanism 9 and the annular air pipe 11a to descend synchronously. After the bottom plate 6b contacts the leather fabric 10, the lifting mechanism 1 drives the air guide pipe 6c to continue to descend, the telescopic tube 1 6a is compressed, and the synchronous flipping mechanism 9 drives the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 to rotate. At the same time, the air inlet 11b1 is docked with the air outlet 6c1, the baffle ring 11c contacts the top of the sealed tube 11b, and the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 perform blowing work. After the baffle ring 11c contacts the top of the sealed tube 11b, the air guide pipe 6c continues to descend, the telescopic tube 2 11d is compressed, and the synchronous flipping mechanism 9 drives the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 to continue to rotate, and the airflow blown out by the transverse blowing mechanism 7 and the longitudinal blowing mechanism 8 flattens the leather fabric 10.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
