Description

Technical Field

[0001] The present application relates to the field of palletizing technology, and in particular to a leather palletizing system. Background Art

[0002] When processing leather, the leather manufacturing industry often needs to stack leather for easy transfer or storage. Traditionally, stacking leather is done manually, which is labor-intensive and increases manufacturing costs. Therefore, palletizers that can automatically stack leather have emerged.

[0003] Existing palletizers such as Figure 1 As shown, it includes a leather feeding mechanism 1, a conveyor frame 21, a yarding stool 3 and a conveying assembly 25; the conveyor frame 21 is located between the leather feeding mechanism 1 and the yarding stool 3, and the conveying assembly 25 is used to drive the conveyor frame 21 to move back and forth between the leather feeding mechanism 1 and the yarding stool 3; the leather feeding mechanism 1 is used to convey leather to the conveyor frame 21, and the conveyor frame 21 is provided with a conveyor belt, and the conveying direction of the conveyor belt is parallel to the moving direction of the conveyor frame 21; in actual operation, the conveyor frame 21 is driven by the conveying assembly 25 to move to the bottom of the leather feeding mechanism 1, so that the leather output by the leather feeding mechanism 1 can be moved to the conveyor frame The conveyor belt on 21 is then driven by the conveying component 25 to move toward the yarding stool 3. At the same time, the conveyor belt conveys the leather to the yarding stool 3. The end of the leather near the yarding stool 3 first contacts the yarding stool 3 and falls on the yarding stool 3. Then, as the conveyor belt is conveyed, most of the leather falls on the yarding stool 3. That is, the center of gravity of the leather has been transferred to the yarding stool 3. At this time, the conveying component 25 drives the conveying frame 21 to move away from the yarding stool 3. The leather currently stranded on the conveyor belt will move toward the yarding stool 3 under the pull of the center of gravity of the leather, and finally the entire leather is successfully stacked on the yarding stool 3.

[0004] With respect to the above-mentioned related technologies, the inventors found that after at least one piece of leather is stacked on the stacking bench, starting from the second piece of leather, combined with the above-mentioned technology, when the center of gravity of the leather falls on the stacking bench, the conveyor frame moves in the direction away from the stacking bench. At this time, the leather stranded on the conveyor belt will be pulled onto the stacking bench by the leather on the stacking bench. At the same time, since the moving direction of the conveyor frame is opposite to the moving direction of the leather, the friction between the conveyor belt and the leather will also pull the leather, so that the leather has a tendency to move away from the stacking bench. In this case, if the leather material is lighter, the leather on the stacking bench is also easily pulled and moves relative to the leather already stacked on the stacking bench, resulting in the leather being unevenly stacked on the stacking bench, which is inconvenient to subsequently remove the stacked leather from the stacking bench stably. Summary of the Invention

[0005] In order to improve the neatness of leather when stacked on a stacking bench so that the stacked leather can be stably removed from the stacking bench at one time later, the present application provides a leather stacking system.

[0006] This application provides a leather palletizing system, which adopts the following technical solutions:

[0007] A leather stacking system includes a leather feeding mechanism, a conveying mechanism and a stacking stool, wherein the leather feeding mechanism is used to convey leather to the conveying mechanism, the conveying mechanism is used to move back and forth between the leather feeding mechanism and the stacking stool, and the conveying mechanism is also used to receive the leather output by the leather feeding mechanism and transfer the leather to the stacking stool; the system also includes a receiving plate, a rotating assembly and a moving assembly, wherein the receiving plate is located between the stacking stool and the conveying mechanism and is used to receive the leather transferred by the conveying mechanism, the rotating assembly is used to drive the receiving plate to rotate in a direction away from or close to the stacking stool, and the moving assembly is used to drive the receiving plate to slide in a direction away from or close to the stacking stool.

[0008] By adopting the above technical solution, the receiving plate is driven by the moving component to move toward the stacking stool, and the receiving plate is driven by the rotating component to rotate toward the stacking stool, so that the receiving plate finally moves above the stacking stool and is located in the transmission direction of the conveying mechanism and is in a horizontal state. At this time, the leather conveyed by the feeding mechanism can be received by the receiving plate, and then the moving component and the rotating component are used to control the receiving plate to move in the direction away from the stacking stool while rotating in the direction away from the stacking stool (specifically, it can be rotated downward). At this time, the receiving plate is tilted, and the leather on the receiving plate will be moved to the stacking stool under the guidance of the receiving plate to achieve stacking; in summary, the present application realizes the transition transmission of leather between the conveying mechanism and the stacking stool by setting the receiving plate, which reduces the situation where the leather falls directly from the conveying mechanism onto the stacking stool due to the influence of the reverse movement of the conveying mechanism, and the leather is dislocated relative to the leather already stacked on the stacking stool, which eventually leads to uneven stacking.

[0009] Preferably, the rotating assembly includes a frame, a docking plate, a driving shaft and a rotating member, the driving shaft is rotatably connected to the frame, the docking plate is connected to the driving shaft, and the rotating member is used to drive the driving shaft to rotate; the moving assembly includes a connecting rod and a moving block, one end of the connecting rod is hinged to the frame, and the other end is hinged to the moving block, the moving block is slidably connected to the docking plate, and the moving block is connected to the receiving plate, and the receiving plate is slidably connected to the docking plate through the moving block.

[0010] By adopting the above technical solution, the active rotating shaft is driven to rotate by the rotating member, so that the docking plate and the receiving plate rotate in the direction away from the yarding stool. At the same time, the connecting rod drives the moving block to slide, so that the receiving plate slides in the direction away from the yarding stool, and finally the receiving plate tilts downward. At this time, the leather on the receiving plate detaches from the receiving plate and falls onto the yarding stool under the action of its own weight.

[0011] Preferably, the movable assembly includes a frame, a docking plate, a movable rod and a movable part; one end of the docking plate is connected to the frame, and the other end is inserted into the movable rod, the movable rod is arranged along the length direction of the docking plate, and the movable rod can slide along the length direction of the docking plate, and the movable part is used to drive the movable rod to slide along the length direction of the docking plate; the rotating assembly includes an active rotating shaft and a gear set, the active rotating shaft is rotatably connected to one end of the movable rod away from the docking plate, the gear set is used to drive the active rotating shaft to rotate when the movable rod slides, and the connecting plate is connected to the side wall of the active rotating shaft.

[0012] By adopting the above technical solution, the movable rod is driven by the moving part to move in the direction away from the yarding stool. At the same time, the gear set will drive the active rotating shaft to rotate, so that the receiving plate rotates around the active rotating shaft and tilts during the rotation, thereby guiding the leather on the receiving plate to detach from the receiving plate and fall onto the yarding stool.

[0013] Preferably, the stacking stool is provided with a first adsorption component, and the first adsorption component is used to adsorb the leather stacked on the stacking stool onto the stacking stool.

[0014] By adopting the above technical solution, whenever leather falls onto the stacking stool, the leather stacked on the stacking stool can be adsorbed by the first adsorption component, further reducing the situation where adjacent leather on the stacking stool is misplaced, stacked unevenly, or even falls off the stacking stool.

[0015] Preferably, it also includes a first detection module, a controller and a correction mechanism, the first detection module is electrically connected to the controller, and the correction mechanism is controlled by the controller; the first detection module is used to detect the initial position of the leather when it moves to the receiving plate, and the initial position refers to the position of the leather on the receiving plate when it moves to the receiving plate via the conveying mechanism; the correction mechanism is used to adjust the position of the leather on the receiving plate, and the controller is used to obtain the initial position and compare the initial position with the preset standard position, and based on the comparison result, control the correction mechanism to adjust the leather to the preset standard position.

[0016] By adopting the above technical solution, the preset standard position meets the following requirements: when the leather in the preset standard position detaches from the receiving plate and falls onto the stacking stool, its falling position is just enough to prevent it from detaching from the stacking stool; by setting a first detection module, a controller and a correction mechanism, the initial position of the leather is adjusted to avoid the initial position of the leather deviating too much from the stacking stool, which causes it to detach from the stacking stool when it detaches from the receiving plate.

[0017] Preferably, the correction mechanism includes a first conveyor belt for conveying leather, the first conveyor belt is controlled by a controller, the first conveyor belt is located on a receiving plate, and the conveying direction of the first conveyor belt is perpendicular to the conveying direction of the conveying mechanism.

[0018] By adopting the above technical solution, when the leather moves to the receiving plate, the leather falls onto the first conveyor belt. The controller can control the start of the first conveyor belt according to the comparison result, so that the first conveyor belt drives the leather to move relative to the receiving plate, thereby adjusting the initial position of the leather and moving the leather to the preset standard position.

[0019] Preferably, the correction mechanism includes a sliding plate, a sliding member and a second adsorption member, the sliding plate is used to receive the leather moved to the receiving plate, the sliding plate is slidably connected to the receiving plate, the sliding member is used to drive the sliding plate to slide on the receiving plate, and the second adsorption member is arranged on the sliding plate to form negative pressure or positive pressure on the upper surface of the sliding plate; the second adsorption member and the sliding member are controlled by a controller.

[0020] By adopting the above technical solution, when the leather moves to the receiving plate, the leather falls on the sliding plate. The controller can start the sliding member and the second adsorption member according to the comparison result, so that the second adsorption member can adsorb the leather to the sliding plate, and when the sliding plate moves, the leather moves with the sliding plate, thereby adjusting the initial position of the leather and moving the leather to the preset standard position.

[0021] Preferably, it also includes a second detection module and a third detection module, the second detection module and the third detection module are both electrically connected to the controller, and the rotating component and the moving component are controlled by the controller; the second detection module is used to detect whether the leather conveyed by the leather feeding mechanism is completely moved to the conveying mechanism, and the controller is used to control the opening and closing of the conveying mechanism based on the detection result of the second detection module, and the third detection module is used to detect whether the leather is completely conveyed to the receiving plate, and the controller is used to control the opening and closing of the rotating component and the moving component based on the detection result of the third detection module.

[0022] By adopting the above technical solution, the setting of the second detection module and the third detection module realizes automatic monitoring of the leather conveying position, so that the controller controls the conveying mechanism and the flipping and sliding of the receiving plate according to the leather conveying position, further improving the automation and intelligence of leather palletizing.

[0023] Preferably, it also includes a fourth detection module, a spacing adjustment component, and a prompt module. The fourth detection module and the prompt module are electrically connected to the controller. The spacing adjustment component is controlled by the controller. The fourth detection module is used to detect the thickness of the leather stacked on the stacking stool. The spacing adjustment component is used to adjust the distance between the top end of the stacking stool and the receiving plate. The controller is used to control the spacing adjustment component to adjust the distance between the top end of the stacking stool and the receiving plate based on the thickness of the leather. The controller is also used to control the prompt module to start when the thickness of the leather is greater than a preset value.

[0024] By adopting the above technical solution, the setting of the fourth detection module realizes the automatic detection of the thickness of the leather on the stacking stool. The spacing adjustment component is used to adjust the distance between the top of the stacking stool and the receiving plate to avoid the rotation of the receiving plate being hindered when the thickness of the leather on the stacking stool becomes larger and larger. When the leather thickness reaches a value greater than the preset value, the controller will start the prompt module so that the prompt module sends a signal to remind the operator to remove all the leather on the stacking stool.

[0025] Preferably, the upper surface of the receiving plate is slidably connected to a shift rod, the shift rod is connected to a shift member, and the shift member is used to drive the shift rod to slide on the receiving plate.

[0026] By adopting the above technical solution, after the leather is moved to the receiving plate, the lever is located between the leather and the receiving plate, and the leather can be driven to slide by the lever member, so that the lever can flatten the leather during the movement, thereby reducing the occurrence of leather edge folding and warping, which causes the leather to become uneven when it subsequently falls on the stacking stool.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. This application realizes the transition of leather between the conveyor mechanism and the stacking bench by providing a receiving plate, which reduces the problem that when the leather falls directly from the conveyor mechanism onto the stacking bench, it is affected by the reverse movement of the conveyor mechanism, causing the leather to be misaligned with the leather already stacked on the stacking bench, resulting in uneven stacking.

[0029] 2. The second and third detection modules enable automatic monitoring of the leather conveying position, allowing the controller to control the conveying mechanism and the flipping and sliding of the receiving plate based on the leather conveying position, further improving the automation and intelligence of leather palletizing.

[0041] The following is combined with Figure 2-9 This application is described in further detail.

[0042] Example 1

[0043] Example 1 of the present application discloses a leather palletizing system. Figure 2 The leather stacking system includes a leather feeding mechanism 1, a conveying mechanism 2 and a stacking stool 3. The leather feeding mechanism 1, the conveying mechanism 2 and the stacking stool 3 are arranged in sequence along the leather conveying direction; the leather feeding mechanism 1 can specifically be a conveyor belt, and the conveying mechanism 2 is used to receive the leather conveyed by the leather feeding mechanism 1, and move it to the stacking stool 3, and then convey the leather to the stacking stool 3. A receiving plate 4 is also provided between the conveying mechanism 2 and the stacking stool 3. The leather stacking system also includes a rotating component 5 and a moving component 6. The receiving plates 4 are symmetrically arranged on both sides of the stacking stool 3 and are located above the stacking stool 3. The rotating component 5 is used to drive the receiving plate 4 to rotate in a direction close to or away from the stacking stool 3, such as rotating downward to move away from the stacking stool 3, and rotating upward to approach the stacking stool 3. The moving component 6 is used to drive the receiving plate 4 to slide in a direction close to or away from the stacking stool 3. When the receiving plate 4 is turned to a horizontal state and moved to a position close to the stacking stool 3, the receiving plate 4 is just located in the conveying direction of the conveying mechanism 2, and can receive the leather conveyed by the conveying mechanism 2. When the leather is completely moved onto the receiving plate 4, the receiving plate 4 can be driven to rotate downward by the rotating component 5, and at the same time, the receiving plate 4 can be driven to move in the direction away from the stacking stool 3 to achieve the inclination of the receiving plate 4, so that the leather on the receiving plate 4 is separated from the receiving plate 4 and falls onto the stacking stool 3, realizing the stacking operation.

[0044] Reference Figure 2 The conveying mechanism 2 specifically includes a conveying frame 21, a transition rod group 22 provided on the conveying frame 21, a second conveyor belt 23 provided on the conveying frame 21, a pressure roller 24 rotatably connected to the conveying frame 21, and a conveying assembly 25 for driving the conveying frame 21 to move back and forth between the leather feeding mechanism 1 and the yarding stool 3. The transition rod group 22 includes a plurality of transition rods welded to the conveying frame 21; there are a plurality of second conveyor belts 23, which are evenly arranged on the conveying frame 21. The conveying direction of the second conveyor belts 23 is parallel to the conveying direction of the leather by the leather feeding mechanism 1 and the moving direction of the conveying frame 21, and the yarding stool 3 is located on the extension line of the above direction.

[0045] Reference Figure 2 A gap 26 is reserved between the second conveyor belt 23 and the pressure roller 24 for the leather to pass through. A motor 241 is provided on the conveyor frame 21 for driving the pressure roller 24 to rotate; the conveying component 25 can be a combination structure of a motor and a screw rod, or a cylinder, or a pneumatic slide, etc., by threading the conveyor frame 21 with the screw rod, or connecting the conveyor frame 21 to the cylinder piston rod, or connecting the conveyor frame 21 to the driving end of the pneumatic slide, so as to realize the reciprocating movement of the conveyor frame 21.

[0046] Reference Figure 2 When the leather leaves the leather feeding mechanism 1, the transition rod group 22 receives the leather, and the end of the leather contacts the conveyor belt on the conveyor frame 21 and moves toward the direction close to the gap 26 under the conveying action of the second conveyor belt 23. At the same time, the conveyor frame 21 can be driven by the conveying component 25 to move above the yarding stool 3 and the receiving plate 4, and the leather passes through the gap 26 and moves onto the yarding stool 3 and the receiving plate 4. In addition, the pressure roller 24 can be driven to rotate according to the direction of arrow C in the figure, so that the pressure roller 24 cooperates with the second conveyor belt 23 to transport the leather flatly to the yarding stool 3 and the receiving plate 4.

[0047] Reference Figure 2 The rotating component 5 includes a frame 51, a docking plate 52, a driving shaft 53 and a rotating member 54. The rotating member 54 can be specifically a servo motor. The rotating member 54 is installed on the frame 51, and the conveying frame 21 is slidingly connected to the frame 51; the driving shaft 53 is rotatably connected to the frame 51, and the docking plate 52 is fixedly sleeved on the driving shaft 53; the moving component 6 includes a connecting rod 61 and a moving block 62. The connecting rod 61 is made of elastic material, one end of the connecting rod 61 is hinged to the frame 51, and the other end is hinged to the moving block 62. The moving block 62 is slidingly connected to the docking plate 52, and the moving block 62 is connected to the receiving plate 4.

[0048] Reference Figure 2 and Figure 3The leather palletizing system includes a second detection module 72, a third detection module 73, and a controller 7. The second detection module 72, the third detection module 73, and the rotating member 54 are all electrically connected to the controller 7. The conveying assembly 25 is controlled by the controller 7. The second detection module 72 is used to detect whether a single leather conveyed by the leather feeding mechanism 1 has completely moved onto the conveying mechanism 2. The third detection module 73 is used to detect whether a single leather conveyed by the conveying mechanism 2 has completely separated from the conveying mechanism 2 and moved onto the receiving plate 4.

[0049] Both the second detection module 72 and the third detection module 73 can be timers. According to the preset transmission speed of the leather feeding mechanism 1 and the second conveyor belt 23, combined with the total length of a single leather, the transmission time of a single leather can be calculated in advance, and the leather feeding mechanism 1 can be guaranteed to continuously and uninterruptedly transport the leathers one by one. When the timing time of the second detection module 72 or the third detection module 73 reaches the transmission time, the detection result is sent to the controller 7, and the timing is reset and restarted.

[0050] Reference Figure 2 and Figure 3 The controller 7 is used to obtain the detection results of the second detection module 72 and the third detection module 73, and when the leather is completely moved onto the conveying mechanism 2, control the conveying assembly 25 to drive the conveying frame 21 to move, so that the conveying frame 21 first moves to above the yarding stool 3 and the receiving plate 4, and then moves in the opposite direction to reset; during this process, the second conveyor belt 23 is always in the starting state; the controller 7 is also used to control the rotating member 54 to start when the leather is completely moved onto the receiving plate 4 and the yarding stool 3, and rotate it in a specified rotation direction for a specified time, so that the receiving plate 4 moves in a direction away from the yarding stool 3 and rotates downward, so that the leather located on the receiving plate 4 hangs down under the action of its own weight and finally falls completely on the yarding stool 3; when the rotating member 54 rotates in the specified rotation direction for a specified time, the controller 7 drives the rotating member 54 to reverse and reset, so that the receiving plate 4 moves again in a direction close to the yarding stool 3 and rotates upward to a horizontal state.

[0051] The implementation principle of a leather stacking system disclosed in an embodiment of the present application is as follows: leather is continuously conveyed to the conveying mechanism 2 through the leather feeding mechanism 1; when a single leather moves onto the conveying mechanism 2, the controller 7 controls the conveying mechanism 2 to move to a position above the stacking stool 3 and two receiving plates 4, and conveys the leather to the receiving plate 4 through the conveying mechanism 2; when the single leather is completely moved onto the receiving plate 4, the controller 7 controls the rotating member 54 to start, so that the receiving plate 4 moves and tilts in a direction away from the stacking stool 3, so that the leather located on the receiving plate 4 is separated from the receiving plate 4 and completely falls onto the stacking stool 3, thereby realizing the leather stacking operation.

[0052] Example 2

[0053] The difference between Example 2 of the present application and Example 1 is that: Figure 4 , also includes a first detection module 71 and a correction mechanism 8, the first detection module 71 is electrically connected to the controller 7, and the correction mechanism 8 is controlled by the controller 7; the first detection module 71 can specifically be a camera device, which is installed on the frame 51, and is used to capture the initial position of the leather when it moves to the receiving plate 4 in the form of an image. Since the conveying direction of the conveyor belt on the conveying rack 21 is parallel to the moving direction of the conveying rack 21, the first detection module 71 can specifically obtain the position of the leather when it moves to the receiving plate 4 by capturing the position of the leather when it moves to the conveying rack 21.

[0054] The correction mechanism 8 is used to adjust the leather on the receiving plate 4 to a preset standard position. The preset standard position satisfies the following conditions: the center of the leather located at the preset standard position coincides with the center of the yard stool 3. The correction mechanism 8 specifically includes a first conveyor belt 81 provided on each receiving plate 4. The first conveyor belt 81 is controlled by a controller 7. The controller 7 is used to obtain an image detected by the first detection module 71 (the image includes the conveyor rack 21 and the leather located on the conveyor rack 21). The controller 7 determines the initial position of the leather based on the above image. The initial position can be specifically represented in the form of a coordinate set. The controller 7 then compares the coordinate set corresponding to the initial position with the coordinate set corresponding to the preset standard position, calculates the deviation distance and deviation direction, and then controls the first conveyor belt 81 to drive the leather to move according to the deviation direction, so that the leather on the receiving plate 4 moves to the preset standard position.

[0055] Example 3

[0056] The difference between Example 3 of the present application and Example 2 is that: Figure 5 and Figure 6 The correcting mechanism 8 includes a sliding plate 84, a sliding member 82 and a second adsorption member 83 arranged on each supporting plate 4; a sliding groove 41 is opened on the upper surface of the supporting plate 4 along its length direction, and the sliding plate 84 is inserted in the sliding groove 41, and the sliding member 82 is used to drive the sliding plate 84 to slide back and forth along the length direction of the sliding groove 41; the sliding member 82 specifically includes a first motor 821, a first gear 822 and a first rack 823 that are meshed with each other, the first motor 821 is installed on the corresponding side wall of the sliding plate 84, the driving end of the first motor 821 is inserted through the sliding plate 84, and is fixedly inserted at the rotation center of the first gear 822, the first rack 823 is slidably connected to the inside of the sliding plate 84 along the length direction of the sliding plate 84, and the side wall of the sliding plate 84 is fixedly connected to the first rack 823.

[0057] The second adsorption component 83 can specifically be an air pump with an air pipe connected to the air inlet end. The air pump is installed inside the skateboard. The air pipe at the air inlet end of the air pump passes through the upper surface of the skateboard, and the air outlet end of the air pump passes through the skateboard and is connected to the external environment; the second adsorption component 83 and the first motor 821 are both electrically connected to the controller 7; the controller 7 is used to control the start-up of the second adsorption component 83 to form a negative pressure on the upper surface of the sliding plate 84, thereby adsorbing the leather on the upper surface of the sliding plate 84. At the same time, the controller 7 controls the start-up of the first motor 821 to drive the sliding plate 84 to slide, thereby realizing the adjustment of the position of the leather on the receiving plate 4.

[0058] Example 4

[0059] The difference between Example 4 of the present application and Example 1 is that: Figure 7 The stacking stool 3 is provided with a first adsorption member 31, which can be used to form a negative pressure on the upper surface of the stacking stool 3, so that the leather stacked on the stacking stool 3 can be firmly placed on the stacking stool 3 by being adsorbed, and the leather can be prevented from falling off the stacking stool 3. The first adsorption member 31 can be specifically an air pump with an air pipe connected to the air inlet end. The air pump is installed on the stacking stool 3, and the air inlet end of the air pump passes through the upper surface of the stacking stool 3.

[0060] Reference Figure 7 and Figure 8 , also includes a fourth detection module 74, a spacing adjustment component 32 and a prompt module 75. The fourth detection module 74 and the prompt module 75 are electrically connected to the controller 7, and the spacing adjustment component 32 is controlled by the controller 7; the spacing adjustment component 32 can specifically include a telescopic sleeve installed on the lower surface of the yarding stool 3, and a motor screw combination structure for driving the telescopic sleeve to extend and retract; the fourth detection module 74 can specifically be a gravity sensor embedded in the upper surface of the yarding stool 3, so as to detect the total weight of the leather stacked on the yarding stool 3, and the controller 7 is used to obtain the detection result of the fourth detection module 74, and based on the preset single leather weight and single leather thickness, calculate the number of leathers stacked on the yarding stool 3 and the leather thickness. The controller 7 is also used to determine the distance between the top of the stacking stool 3 and the receiving plate 4 in a horizontal state based on the calculated leather thickness and the preset initial distance, wherein the initial distance refers to the distance between the top of the stacking stool 3 and the receiving plate 4 in a horizontal state when no leather is stacked on the stacking stool 3; the controller 7 is used to control the distance adjustment component 32 to drive the stacking stool 3 to rise and fall according to the determined distance, so as to adjust the distance to the preset standard distance; in addition, the controller 7 is also used to control the prompt module 75 to start when the leather thickness is greater than the preset value, wherein the prompt module 75 can specifically be an audible and visual alarm, so as to remind the operator to remove the leather stacked on the stacking stool 3 in time.

[0061] In addition, the first adsorption component 31 can be controlled by the controller 7 so that the controller 7 can control the opening and closing of the first adsorption component 31 and the suction force of the first adsorption component 31 in real time according to the leather thickness detected by the fourth detection module 74 to ensure that the first adsorption component 31 can absorb all the leather stacked on the stacking stool 3.

[0062] Reference Figure 7 and Figure 8 The second gear 433 is fixedly mounted on the polished rod 432, and the second rack 434 is welded to the docking plate 52 in a direction parallel to the length of the docking plate 52.

[0063] When the leather moves onto the receiving plate 4, the lever 42 is located between the leather and the receiving plate 4. As the receiving plate 4 slides along the length of the docking plate 52 and gradually moves away from the stacking stool 3, the second gear 433 rotates under the drive of the second rack 434, causing the bidirectional screw 432 to rotate and drive the two levers 42 to move away from each other. During the movement, the levers 42 smooth the leather to prevent wrinkles on the leather flanging. At this time, due to the tilting movement of the receiving plate 4, the leather detaches from the receiving plate 4 and falls onto the stacking stool 3, completing the leather stacking operation. Accordingly, when the receiving plate 4 slides back toward the stacking stool 3, the second gear 433 rotates in the opposite direction under the drive of the second rack 434, causing the two levers 42 to move back toward each other.

[0064] Example 5

[0065] The difference between Example 5 of the present application and Example 1 is: Figure 9 The moving assembly 6 includes a frame 51, a docking plate 52, a movable rod 63 and a moving part 64. The docking plate 52 is vertically welded to the frame 51. The other end of the docking plate 52 is inserted into the end of the movable rod 63. The end of the movable rod 63 is provided with a makeshift groove for the docking plate 52 to slide along its length direction. The moving part 64 is used to drive the movable rod 63 to slide relative to the docking plate 52. The moving part 64 can specifically be a cylinder, and the moving part 64 is controlled by the controller 7.

[0066] Reference Figure 9 The rotating assembly 5 includes a driving shaft 53 and a gear set 55. The driving shaft 53 is rotatably connected to one end of the movable rod 63 away from the docking plate 52, and the receiving plate 4 is fixedly sleeved on the driving shaft 53; the gear set 55 includes a third rack 552 and a third gear 551. The third gear 551 is fixedly sleeved on the driving shaft 53. The third rack 552 is fixedly connected to the docking plate 52 along the length direction of the docking plate 52, and the third gear 551 is meshed with the third rack 552.

[0067] Each connecting plate 4 is slidably connected to two shift rods 42, and each connecting plate 4 is provided with a shift piece 43 for driving the shift rod 42 to slide. The shift piece 43 includes a shift block 431, a bidirectional screw rod 432 and a second motor 435. The second motor 435 is fixedly mounted on the connecting plate 4, and the driving end of the second motor 435 is welded to the driving end of the bidirectional screw rod 432. The bidirectional screw rod 432 is rotatably connected to the corresponding connecting plate 4. The shift block 431 and the shift rod 42 are arranged in a one-to-one correspondence. The end wall of the shift rod 42 is welded to the corresponding shift block 431, and the shift block 431 is threadedly sleeved on the bidirectional screw rod 432. The two shift blocks 431 on each bidirectional screw rod 432 are arranged at both ends of the bidirectional screw rod 432.

[0068] After the leather moves from the conveying mechanism 2 to the receiving plate 4, the controller 7 starts the moving member 64 to move the receiving plate 4 away from the yard stool 3. During the movement, the third gear 551 rotates driven by the third rack 552. At this time, the side of the receiving plate 4 away from the active rotating shaft 53 is tilted upward, so that the leather on the receiving plate 4 is separated from the receiving plate 4 and falls onto the yard stool 3, completing the yard stool 3 operation.

[0069] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
