Description

Technical Field

[0001] This invention relates to the field of sorting and conveying platform technology, and in particular to a sorting and conveying platform for stacked finished leather products. Background Technology

[0002] In the leather product manufacturing process, after the finished leather undergoes tanning and finishing processes, it needs to be sorted and transferred according to specifications and categories before being transported to the cutting or warehousing station. Finished leather is mostly sheet-like flexible material, and after processing, it is often stacked, requiring sorting operations. In existing production scenarios, a sorting conveyor can be used to receive the stacked finished leather, and the material flow can be completed in conjunction with the conveying mechanism. Alternatively, manual labor can be used in conjunction with the conveying equipment to classify and transfer the leather, transporting different batches of finished leather to the corresponding discharge positions, thereby connecting the subsequent processing and storage processes of the leather and realizing the flow and transfer of finished leather between different workstations.

[0003] A leather conveying mechanism for a 3D intelligent leather inspection and scanning device, with announcement number CN209427687U, includes a frame. A rotating shaft fixing plate is fixedly installed at the top of the frame, with a rotating shaft in the middle of the fixing plate. A conveyor belt is fitted onto the rotating shaft. A second cylinder fixing plate is installed on the side end of the fixing plate, with a second cylinder at its top. A second push plate is connected to the output end of the second cylinder. A motor support plate is located on one side of the second cylinder fixing plate, with a motor at its top. This invention conveys the leather to be inspected via a conveyor belt, then pushes the leather into the inspection table via the second cylinder, and pushes non-conforming products into a receiving box via a first cylinder. This eliminates the need for inspection personnel to sort the leather, effectively saving time and greatly improving inspection efficiency. Furthermore, it eliminates the need for manual collection of non-conforming products, significantly reducing the labor intensity of operators.

[0004] There are still some problems when sorting finished leather products.

[0005] In the sorting process of finished leather, different batches of leather are often mixed and stacked together. At present, most of the sorting is done manually, with each batch of mixed leather being sorted and placed onto a conveyor for feeding. This manual sorting operation has low overall processing efficiency, requires a large amount of manpower, and is difficult to adapt to the needs of continuous production of large quantities of leather. Furthermore, leather is a flexible sheet material, and when multiple layers are stacked, the materials are squeezed and misaligned, making the leather surface prone to wrinkles. These wrinkles are directly carried into subsequent processing steps, which adversely affects leather cutting and subsequent product shaping, increases the difficulty of subsequent processing steps, and is not conducive to ensuring the processing quality of finished leather. Summary of the Invention

[0006] The purpose of this application is to provide a finished leather stacking sorting and conveying platform. This application uses a sorting component to pick up the leather stacked on the stacking platform, and then uses a conveying component to sort different batches of leather onto the corresponding conveying platform. The roller pressing component inside the conveying platform rolls and flattens the surface of the leather to avoid wrinkles.

The pulley is provided in pairs, and a transmission belt is sleeved between the pulleys. The top end of the drive shaft is fixedly connected to the output end of a first motor, and the first motor is fixedly mounted on the pallet.

[0010] Preferably, the sorting assembly includes pulleys, docking plates, a carrying plate, a mounting block, a first cylinder, and a base plate; two sets of pulleys are provided, the pulleys are rotatably connected to the surface of the sliding rod, the pulleys are rotatably connected to both ends of the docking plates, a pair of docking plates are provided, a carrying plate is fixedly installed between the pair of docking plates, a mounting block is fixedly installed on one side of the carrying plate, the mounting block is pressed onto the transmission belt by bolts, and a first cylinder is fixedly installed in the middle of the carrying plate.

[0011] Preferably, the telescopic end of the first cylinder is fixedly connected to the base plate, and two sets of guide rods are fixedly connected to the top of the base plate, with the top ends of the guide rods extending to the top of the carrying plate.

[0012] Preferably, a vacuum pump is fixedly installed on both sides of the top surface of the base plate, and an air pipe is fixedly connected to the vacuum pump. The other end of the air pipe passes through the base plate and is fixedly connected to a suction cup. The suction cup is fixedly installed at the four corners of the bottom surface of the base plate.

[0013] Preferably, a pair of fans are fixedly installed at the top of the base plate, and air ducts are fixedly connected to the pair of fans. The air ducts are fixedly installed on the mounting frame, and the mounting frame is fixedly connected to the base plate. A barcode reader is installed at the bottom of the base plate.

[0014] Preferably, the processing box is further equipped with a roller pressing assembly, which includes a placement plate, a receiving plate, and driven rollers; the placement plate is horizontally installed on the inner wall of the processing box, the receiving plate is fixedly installed on the placement plate, and several sets of driven rollers are rotatably connected to the receiving plate.

[0015] Preferably, a rod is fixedly connected to the inner wall of the processing box, an arm plate is rotatably connected to the rod, a pressure roller is rotatably connected to one end of the arm plate, one end of the pressure roller is fixedly connected to the output end of a second motor, and the second motor is fixedly mounted on the arm plate.

With the sliding guide of the pulley and the slide bar, the sorting component moves smoothly and steadily as a whole, and can accurately move to the corresponding work position on the conveyor table to complete the transfer and loading of leather, thereby improving the overall continuity of the equipment operation.

[0018] 2. During the material handling operation, the first cylinder pushes the base plate to move, and the guide rod plays a sliding guiding role to ensure the smooth movement of the base plate. The suction cup relies on the vacuum pump to achieve adsorption and gripping of the leather. At the same time, the fan and air duct blow airflow into the side seams of the leather, forming an air layer isolation between the leather layers, eliminating the problem of negative pressure adsorption and adhesion between leather layers, which is conducive to the suction cup reliably gripping a single piece of leather and reducing the risk of picking up multiple pieces of leather together.

[0019] 3. After the leather is fed into the processing box, it is conveyed by the driven roller. The second cylinder drives the arm plate to swing, so that the pressure roller presses the surface of the leather. The pressure roller and the driven roller work together to perform roller pressing on the leather, which can flatten the leather, effectively solve the problem of wrinkles caused by leather stacking, ensure the flatness of the leather surface in subsequent processing, and improve the processing quality of finished leather.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Reference Figure 1 - Figure 8 The illustrated finished leather stacking and sorting conveyor includes a conveyor platform 100, a pair of conveyor platforms 100, each conveyor platform 100 is equipped with a processing box 102, an industrial camera 103 is installed at the top of the inlet of the processing box 102, a stacking platform 104 is provided between the pair of conveyor platforms 100, and limit plates 105 are fixedly connected to the four corners of the top of the stacking platform 104; a conveying assembly 200 is installed on the conveyor platform 100 for sorting materials; and a sorting assembly 300 is provided on the conveying assembly 200 for picking up materials.

[0026] It should be noted that in the identification of finished leather products, most of the identification is based on the printed markings on the surface. The markings can be identified by the barcode reader 314. Different batches of leather are transported to the corresponding conveyor table 100 by the conveyor assembly 200. Before the leather is transported into the processing box 102 by the conveyor table 100, the leather is identified again by the industrial camera 103 to improve the accuracy of leather sorting. Both the barcode reader 314 and the industrial camera 103 are electrically connected to the existing processing unit through wires. The specific working principle between them is based on existing technology and will not be elaborated on here. The driven roller 403 rotates by the existing technology of motor, gear and chain.

[0027] As one embodiment of this invention, the conveying assembly 200 includes a side plate 201, a bracket 202, a slide bar 203, and a pallet 204. The bottom end of the side plate 201 is fixedly connected to one side of the conveying table 100. A bracket 202 is fixedly connected laterally to one side of the top end of the side plate 201. A pair of brackets 202 are provided. A pair of slide bars 203 are fixedly connected between the two ends of the pair of brackets 202. A pallet 204 is fixedly connected to the surface of the side plate 201. A pair of pallets 204 are provided. One end of each pair of pallets 204 is rotatably connected to a drive shaft 205. A pulley 206 is fixedly connected to the bottom end of the drive shaft 205. A pair of pulleys 206 are provided, and a transmission belt 207 is sleeved between the pulleys 206. The top end of the drive shaft 205 is fixedly connected to the output end of a first motor 208. The first motor 208 is fixedly mounted on the pallet 204.

[0028] Specifically, when the sorting component 300 needs to be moved, the transmission belt 207 is fixed to the mounting block 304 by bolts. The operation of the first motor 208 causes the pulley 206 on the drive shaft 205 to rotate, thereby facilitating the movement of the carrying plate 303 on the mounting block 304 by the transmission belt 207. The carrying plate 303 is fixedly connected to the docking plate 302, and the docking plate 302 is rotatably connected to the pulley 301. The movement of the docking plate 302 is facilitated by the sliding of the pulley 301 on the surface of the slide bar 203, thereby facilitating the movement of the sorting component 300 to the corresponding conveyor table 100 for sorting.

[0029] In one embodiment of this invention, the sorting assembly 300 includes pulleys 301, docking plates 302, a carrying plate 303, mounting blocks 304, a first cylinder 305, and a base plate 306. Two sets of pulleys 301 are provided, rollingly connected to the surface of the sliding rod 203, and rotatably connected to both ends of the docking plates 302. A pair of docking plates 302 are provided, and a carrying plate 303 is fixedly installed between the pair of docking plates 302. A mounting block 304 is fixedly installed on one side of the carrying plate 303 and bolted to the transmission belt 207. A first cylinder 305 is fixedly installed in the middle of the carrying plate 303, and the telescopic end of the first cylinder 305 is fixedly connected to the base plate 306. Next, two sets of guide rods 307 are fixedly connected to the top of the base plate 306. The top of the guide rods 307 extends to the top of the carrying plate 303. Vacuum pumps 308 are fixedly installed on both sides of the top surface of the base plate 306. Air pipes 309 are fixedly connected to the vacuum pumps 308. The other end of the air pipes 309 passes through the base plate 306 and is fixedly connected to the suction cups 310. The suction cups 310 are fixedly installed at the four corners of the bottom surface of the base plate 306. A pair of fans 311 are fixedly installed at the top of the base plate 306. Air pipes 312 are fixedly connected to the pair of fans 311. The air pipes 312 are fixedly installed on the mounting bracket 313. The mounting bracket 313 is fixedly connected to the base plate 306. A barcode reader 314 is installed at the bottom of the base plate 306.

[0030] Specifically, when the carrier plate 303 moves to the top of the stacking platform 104 to pick up the leather, the first cylinder 305 pushes the base plate 306, which facilitates the sliding of the guide rod 307 on the carrier plate 303, increasing the stability of the base plate 306's movement. The base plate 306 moves to the surface of the leather, causing the suction cup 310 to adhere to the surface of the leather. The operation of the vacuum pump 308 causes the suction cup 310 to adsorb the leather. The operation of the fan 311 causes the air duct 312 to blow air into the gaps between the leather layers, forming an airflow isolation layer between adjacent leather layers, weakening the adhesion force of the leather, and making it easier for the suction cup 310 to pick up the leather.

[0031] In one embodiment of this invention, a roller pressing assembly 400 is also installed inside the processing box 102. The roller pressing assembly 400 includes a placement plate 401, a receiving plate 402, and driven rollers 403. The placement plate 401 is horizontally installed on the inner wall of the processing box 102. The receiving plate 402 is fixedly installed on the placement plate 401, and several sets of driven rollers 403 are rotatably connected to the receiving plate 402. A rod 404 is fixedly connected to the inner wall of the processing box 102, and an arm plate 405 is rotatably connected to the rod 404. One end of 405 is rotatably connected to a pressure roller 406. One end of the pressure roller 406 is fixedly connected to the output end of the second motor 407. The second motor 407 is fixedly mounted on the arm plate 405. A crossbar 408 is fixedly connected to the middle position of the arm plate 405. A collar 409 is sleeved on the middle position of the crossbar 408. A positioning rod 410 is fixedly connected to the inner wall of the processing box 102. A second cylinder 411 is rotatably connected to the middle position of the positioning rod 410. The collar 409 is fixedly connected to the telescopic end of the second cylinder 411.

[0032] Specifically, when the leather enters the processing box 102 through the conveyor table 100, the leather is conveyed to the receiving plate 402 by the conveyor table 100. The leather is then conveyed to the bottom of the pressure roller 406 by the driven roller 403. Then, the second cylinder 411 pushes the collar 409, which drives the crossbar 408 to rotate the arm plate 405. The pressure roller 406 is then pressed against the surface of the leather. The operation of the second motor 407 causes the pressure roller 406 to rotate in conjunction with the driven roller 403 to roll and press the surface of the leather, thus preventing wrinkles from appearing on the surface of the leather.

[0033] The working principle of this invention is as follows: When the sorting component 300 needs to be moved, the transmission belt 207 is fixed to the mounting block 304 by bolts. The operation of the first motor 208 causes the pulley 206 on the drive shaft 205 to rotate, thereby facilitating the movement of the carrying plate 303 on the mounting block 304 by the transmission belt 207. The carrying plate 303 is fixedly connected to the docking plate 302, and the docking plate 302 is rotatably connected to the pulley 301. The movement of the docking plate 302 is facilitated by the sliding of the pulley 301 on the surface of the slide bar 203, thereby facilitating the movement of the sorting component 300 to the corresponding conveyor table 100 for sorting.

[0034] When the carrier plate 303 moves to the top of the stacking platform 104 to pick up the leather, the first cylinder 305 pushes the base plate 306, which facilitates the sliding of the guide rod 307 on the carrier plate 303, increasing the stability of the base plate 306. The base plate 306 moves to the surface of the leather, so that the suction cup 310 adheres to the surface of the leather. The operation of the vacuum pump 308 causes the suction cup 310 to adsorb the leather. The operation of the fan 311 causes the air duct 312 to blow air into the gaps between the leather layers, forming an airflow isolation layer between adjacent leather layers, weakening the adhesion force of the leather, and making it easier for the suction cup 310 to pick up the leather.

[0035] When the leather enters the processing box 102 through the conveyor table 100, it is conveyed to the receiving plate 402. The driven roller 403 then conveys the leather to the bottom of the pressure roller 406. The second cylinder 411 pushes the collar 409, which drives the crossbar 408 to rotate the arm plate 405. The pressure roller 406 then presses against the leather surface. The operation of the second motor 407 causes the pressure roller 406 to rotate, which, together with the driven roller 403, rolls the leather surface to prevent wrinkles from forming.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
