[0006] Furthermore, the palletizing preprocessing system also includes: a second detection device connected to the control module, the second detection device being used to detect the height value of the workpiece within a preset area; wherein, when the first detection device detects that the workpiece is located within the preset area and the detection value of the second detection device is less than the preset height value, the first transfer device is controlled to place another workpiece on the workpiece; when the first detection device detects that the workpiece is located within the preset area and the detection value of the second detection device is greater than or equal to the preset height value, the second transfer device is controlled to transfer at least two workpieces after stacking to a preset position.

[0007] Furthermore, when the first detection device does not detect the workpiece, the first transfer device is controlled to transfer the workpiece to the adjustment device.

[0008] Furthermore, the adjustment device includes: a support structure disposed on the worktable, the support structure having a support surface, the support surface being disposed at a first angle with the table surface of the worktable, the support surface being used to support the workpiece; wherein, the adjustment part is retractably disposed relative to the support structure to push the workpiece located on the support surface onto the table surface.

[0009] Furthermore, the adjustment device also includes a drive cylinder, the cylinder body or piston rod of which is the adjustment part; the support structure includes: a first frame; a second frame connected to the first frame, the second frame having a support surface, and the adjustment part being telescopically inserted into the second frame and located above the middle of the second frame.

[0010] Furthermore, the second frame is pivotally connected to the first frame, and the support structure also includes a first driving device, which is driven to connect to the second frame to drive the second frame to rotate around the first frame to adjust the size of the first included angle.

[0011] Furthermore, the positioning component includes: a second driving device for driving the adjusted workpiece to move along a first direction; and a first stop structure, which is disposed opposite to the second driving device to stop the adjusted workpiece; wherein the first direction is set at a second angle to the width direction of the worktable.

[0012] Furthermore, the positioning component also includes: a third driving device for driving the adjusted workpiece to move along the second direction; a second stop structure, which is disposed opposite to the third driving device to stop the adjusted workpiece; wherein the second direction is set at a third angle with the length direction of the worktable, and the stopping areas of the first stop structure and the second stop structure are preset areas.

[0013] Furthermore, the second stop structure is connected to the control module and is movably mounted on the worktable. The second stop structure has a stop state that forms a preset area with the first stop structure and a avoidance state that moves to the bottom of the worktable.

[0026] To address the problem of low palletizing efficiency in existing palletizing systems, this application provides a palletizing preprocessing system.

[0027] like Figures 1 to 3 As shown, the palletizing preprocessing system includes a workbench 10, a first transfer device 20, an adjustment device 30, a positioning component 40, a first detection device, a second transfer device 50, and a control module. The first transfer device 20 is used to transfer workpieces, which have flat and irregular surfaces. The adjustment device 30 is mounted on the workbench 10 and includes an adjustment part for adjusting the workpiece onto the workbench 10 so that the flat surface of the workpiece faces the workbench 10. The positioning component 40 is mounted on the workbench 10 and is used to limit the adjusted workpiece within a preset area. The first detection device is used to detect whether the workpiece is located within the preset area. The second transfer device 50 is used to transfer the stacked workpieces to a preset position. The control module is connected to the first transfer device 20, the first detection device, and the second transfer device 50. Specifically, when the first detection device detects that a workpiece is located within the preset area, it controls the first transfer device 20 to place another workpiece on that workpiece; or, it controls the second transfer device 50 to transfer at least two stacked workpieces to the preset position.

[0028] Applying the technical solution of this embodiment, the first transfer device 20 of the palletizing pretreatment system is used to transfer the workpiece. The workpiece has a flat surface and an irregular surface. An adjustment device 30 and a positioning component 40 are provided on the worktable 10. The adjustment device 30 includes an adjustment part, which is used to adjust the workpiece onto the worktable so that the flat surface of the workpiece faces the worktable 10. The positioning component 40 is used to limit the adjusted workpiece within a preset area. The first detection device is used to detect whether the workpiece is located within the preset area. The second transfer device 50 is used to transfer the stacked workpiece to a preset position. The control module is connected to the first transfer device 20, the first detection device, and the second transfer device 50. In this way, the workpiece is first transferred to the adjustment device 30 by the first transfer device 20. After the flat surface of the workpiece is adjusted to face the worktable 10 by the adjustment device 30, the positioning component 40 restricts the workpiece within the preset area. At this time, the first detection device detects that the workpiece is located in the preset area. The control module controls the first transfer device 20 to place another workpiece on the workpiece to complete the stacking of multiple workpieces. Then, the second transfer device 50 is controlled to simultaneously transfer at least two workpieces after stacking to the preset position, so that the second transfer device 50 can perform palletizing processing on at least two workpieces in a single transfer action. This solves the problem of low palletizing efficiency in the existing palletizing system and improves the palletizing efficiency of the second transfer device 50.

[0029] Compared with existing palletizing systems, the second transfer device 50 in this embodiment can transfer and palletize at least two workpieces in a single transfer action, significantly improving the palletizing efficiency of the second transfer device. Simultaneously, the entire process from workpiece unloading to palletizing is automated, requiring no manual operation, which not only saves manpower but also reduces the production cost of the workpieces.

[0030] In this embodiment, when at least two workpieces are stacked, the irregular surfaces of the two workpieces are arranged facing each other so that the flat surface of the whole formed by the two workpieces faces the table surface of the worktable 10 and the second transfer device 50.

[0031] In this embodiment, the palletizing preprocessing system further includes a second detection device connected to the control module. The second detection device detects the height of a workpiece within a preset area. Specifically, when the first detection device detects a workpiece within the preset area and the detection value of the second detection device is less than the preset height value, the first transfer device 20 is controlled to place another workpiece onto that workpiece. When the first detection device detects a workpiece within the preset area and the detection value of the second detection device is greater than or equal to the preset height value, the second transfer device 50 is controlled to transfer at least two stacked workpieces to a preset position. Thus, the control module can automatically control the actions of the first transfer device 20 or the second transfer device 50 based on the detection value of the second detection device to stack two workpieces or transfer and palletize already stacked workpieces, further improving the automation level of the palletizing preprocessing system.

[0032] Specifically, when the first detection device detects that the workpiece is located within the preset area and the detection value of the second detection device is less than the preset height value, the control module determines that there is only one workpiece in the preset area. At this time, it is necessary to control the first transfer device 20 to directly transfer and stack the other workpiece on the workpiece. When the first detection device detects that the workpiece is located within the preset area and the detection value of the second detection device is greater than or equal to the preset height value, the control module determines that there are two workpieces (already stacked workpieces) in the preset area. At this time, it is necessary to control the second transfer device 50 to synchronously transfer and stack the two stacked workpieces.

[0033] In this embodiment, when the first detection device does not detect a workpiece, the first transfer device 20 is controlled to transfer the workpiece onto the adjustment device 30. In this way, the control module can control the first transfer device 20 to automatically unload the workpiece based on the detection value of the first detection device, further improving the automation level of the palletizing preprocessing system.

[0034] Specifically, if the first detection device does not detect the workpiece, the workpiece (already stacked workpiece) in the preset area has been transferred and stacked by the second transfer device 50, and there is no workpiece on the workbench 10. At this time, the control module controls the first transfer device 20 to transfer the workpiece to the adjustment device 30 to complete the unloading action and start a new round of stacking preprocessing.

[0035] like Figures 1 to 3As shown, the adjustment device 30 includes a support structure 31, which is mounted on the worktable 10. The support structure 31 has a support surface 311, which forms a first angle with the worktable surface 10. The support surface 311 is used to support the workpiece. The adjustment part is extendable relative to the support structure 31 to push the workpiece located on the support surface 311 onto the worktable surface. This supports the workpiece on the adjustment device 30, ensuring its stability. Simultaneously, by pushing the workpiece down, the adjustment part ensures that the flat surface of the workpiece contacts the worktable surface 10, and the irregular surface of the workpiece faces away from the worktable surface. This not only improves the stability of the workpiece on the worktable 10 but also facilitates the stacking of another workpiece on top of it.

[0036] In this embodiment, during the conveying process, in order to increase the friction between the workpiece and the conveyor belt, the irregular surface of the workpiece contacts the conveyor belt. After the workpiece is conveyed to the palletizing pretreatment system, the first transfer device 20 grabs the workpiece with the flat surface of the workpiece facing the first transfer device 20. If the workpiece is placed directly on the worktable 10 at this time, the irregular surface of the workpiece will contact the worktable 10, which will cause the workpiece to be unable to be placed stably on the worktable 10. However, by adjusting the workpiece by the adjustment device 30, it can be ensured that the flat surface of the workpiece contacts the worktable, thereby improving the placement stability of the workpiece.

[0037] Optionally, the adjustment device 30 further includes a drive cylinder 32, where the cylinder body 321 or piston rod 322 serves as the adjustment part. The support structure 31 includes a first frame 312 and a second frame 313, with the second frame 313 connected to the first frame 312. The second frame 313 has a support surface 311, and the adjustment part is telescopically inserted into the second frame 313 and located above the middle of the second frame 313. This arrangement simplifies the formation of the adjustment part, making it easier to manufacture and implement, thus reducing the processing difficulty for workers. Furthermore, it ensures that when the workpiece is driven to rotate by the drive cylinder 32, it rotates towards the worktable 10, allowing the flat surface of the workpiece to contact the surface of the worktable 10, thereby improving the reliability of the adjustment device 30.

[0038] In this embodiment, the piston rod 322 of the drive cylinder 32 is an adjustment part, so as to drive the workpiece to flip through the extension and retraction movement of the piston rod 322.

[0039] In other embodiments not shown in the accompanying drawings, the cylinder body of the drive cylinder is an adjustment part, so as to drive the workpiece to flip by the cylinder body.

[0040] Optionally, the second frame 313 is pivotally connected to the first frame 312. The support structure 31 also includes a first driving device, which is driven by the second frame 313 to drive the second frame 313 to rotate around the first frame 312, thereby adjusting the size of the first included angle. In this way, the size of the first included angle can be adjusted according to parameters such as the workpiece's specifications, dimensions, and center of gravity, thereby improving the support stability of the support structure 31 for the workpiece. Simultaneously, the above configuration achieves automatic adjustment of the first included angle through the first driving device, thus improving the automation level of the palletizing pretreatment system.

[0041] In this embodiment, the first included angle is 105°.

[0042] It should be noted that the value of the first included angle is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the first included angle is 95°, 100°, 110°, 115°, 120°, or 125°.

[0043] Optionally, the positioning assembly 40 includes a second driving device 41 and a first stop structure 42. The second driving device 41 drives the adjusted workpiece to move along a first direction. The first stop structure 42 is disposed opposite to the second driving device 41 to stop the adjusted workpiece. The first direction forms a second angle with the width direction of the worktable 10. Thus, the second driving device 41 drives the adjusted workpiece to move along the first direction until the workpiece contacts the first stop structure 42, causing the workpiece to enter a preset area along the first direction.

[0044] In this embodiment, the second included angle is 90°, and the first direction is consistent with the length direction of the worktable 10.

[0045] It should be noted that the value of the second included angle is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the second included angle can be 75°, 80°, 85°, 95°, 100°, 105°, or 110°.

[0046] Optionally, the positioning assembly 40 further includes a third driving device 43 and a second stop structure 44. The third driving device 43 drives the adjusted workpiece to move along a second direction. The second stop structure 44 is disposed opposite to the third driving device 43 to stop the adjusted workpiece. The second direction forms a third angle with the length direction of the worktable 10, and the stopping areas of the first stop structure 42 and the second stop structure 44 are preset areas. Thus, the third driving device 43 drives the adjusted workpiece to move along the second direction until the workpiece contacts the second stop structure 44, ensuring that the workpiece enters the preset area along the second direction. Simultaneously, the workpiece is confined within the preset area by the combined action of the positioning assembly 40, thereby improving the stacking accuracy of subsequent workpieces.

[0047] In this embodiment, the third included angle is 90°, and the second direction is consistent with the width direction of the worktable 10.

[0048] It should be noted that the value of the third included angle is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the third included angle can be 75°, 80°, 85°, 95°, 100°, 105°, or 110°.

[0049] In this embodiment, the second stop structure 44 is connected to the control module and movably disposed on the worktable 10. The second stop structure 44 has a stop state that forms a preset area with the first stop structure 42, and a avoidance state that moves to below the worktable 10. Specifically, after the workpieces are stacked, the second stop structure 44 is controlled to move from the stop state to the avoidance state. Thus, when positioning or stacking workpieces, both the second stop structure 44 and the first stop structure 42 are in the stop state. This restricts the position of the adjusted workpieces, ensuring they remain within the preset area, thereby improving the accuracy of subsequent workpiece stacking. It also restricts the position of the stacked workpieces, improving the gripping accuracy of the subsequent second transfer device 50. After the workpieces are stacked, the second stop structure 44 is in the avoidance state to avoid the movement path of the second transfer device 50, ensuring that the second transfer device 50 can grip the stacked workpieces.

[0050] Specifically, the second stop structure 44 includes a fourth drive device and a stop part. The fourth drive device is driven to the stop part to drive the stop part to move. The stop part is used to stop the adjusted workpiece. The control module is connected to the fourth drive device to control the operating state of the fourth drive device. When the first detection device detects that the workpiece is located within a preset area and the detection value of the second detection device is greater than or equal to a preset height value, the control module controls the fourth drive device to operate, so as to drive the stop part to move to the avoidance state.

[0051] like Figures 1 to 3 As shown, the worktable 10 has a through hole 11 for the second stop structure 44 to pass through, through which the second stop structure 44 can move up and down. Thus, the aforementioned arrangement of the through hole 11 allows the second stop structure 44 to move up and down through the worktable 10, enabling it to switch between a stopping state and a clearance state; furthermore, it shortens the movement path of the second stop structure 44, thereby making the switching between different working states faster and more sensitive.

[0052] Optionally, the palletizing pretreatment system also includes a buffer component, which is disposed on the table surface of the worktable 10. In this way, the buffer component can buffer the collision between the workpiece and the worktable 10, so as to avoid damage to both the workpiece and the worktable 10 due to mutual collision. This not only extends the service life of the worktable 10, but also reduces the operating cost of the palletizing pretreatment system.

[0053] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0054] The first transfer device of the palletizing pretreatment system is used to transfer workpieces. The workpieces have flat surfaces and irregular surfaces. An adjustment component and a positioning component are provided on the worktable. The adjustment device includes an adjustment part, which is used to adjust the workpieces onto the worktable so that the flat surfaces of the workpieces face the worktable. The positioning component is used to limit the adjusted workpieces within a preset area. A first detection device is used to detect whether the workpieces are located within the preset area. A second transfer device is used to transfer the stacked workpieces to a preset position. The control module is connected to the first transfer device, the first detection device, and the second transfer device. In this way, the workpiece is first transferred to the adjustment device by the first transfer device. After the flat surface of the workpiece is adjusted to face the worktable by the adjustment device, the positioning component restricts the workpiece within the preset area. At this time, the first detection device detects that the workpiece is located in the preset area. The control module controls the first transfer device to place another workpiece on the workpiece to complete the stacking of multiple workpieces. Then, the second transfer device is controlled to simultaneously transfer at least two workpieces after stacking to the preset position, so that the second transfer device can perform palletizing processing on at least two workpieces in a single transfer action. This solves the problem of low palletizing efficiency in the existing palletizing system and improves the palletizing efficiency of the second transfer device.

[0055] Compared with existing palletizing systems, the second transfer device in this application can transfer and palletize at least two workpieces in a single transfer operation, significantly improving the palletizing efficiency of the second transfer device. Simultaneously, the entire process from workpiece unloading to palletizing is automated, requiring no manual operation, thus saving manpower and reducing workpiece production costs.
