[0054] like Figure 1-3 The utility model provides a pallet device for stacking empty pallets and unloading materials. The pallet is provided with grooves on both sides. The grooves serve as support structures for the pallet, which can be used for manual handling or mechanical support. Specifically, the grooves are located on both sides of the pallet and are close to the bottom of the pallet. Alternatively, the grooves can be said to start from the bottom of both sides of the pallet and extend upward.

[0055] As for the pallet device, specifically, the pallet device includes a pallet rack 1, a pallet lifting mechanism 2 and two tray separating mechanisms 3. The pallet rack 1 is provided with a tray hole 13 extending downward and for the tray to pass through. The pallet lifting mechanism 2 is arranged below the tray hole 13. The pallet lifting mechanism 2 is provided with a lifting plate 21. The lifting plate 21 can move up and down. The lifting plate 21 lifts and supports the pallet from the bottom of the tray stack. The two tray separating mechanisms 3 are respectively arranged on both sides of the pallet rack 1. The tray separating mechanism 3 is provided with a support plate 323 that can move laterally and move up and down. The support plate 323 partially extends into the corresponding groove. The support plate 323 lifts and supports the pallet from the grooves on both sides of the pallet. Specifically, the two tray separating mechanisms 3 partially extend into the grooves from both sides of the pallet.

[0056] The pallet lifting mechanism 2 lifts and supports the pallet from the bottom, and the two tray separating mechanisms 3 lift and support the pallet from the grooves on the side. The static support of the pallet is mainly based on the two tray separating mechanisms 3, and the pallet stacking and dropping are achieved through the cooperation of the pallet lifting mechanism 2 and the two tray separating mechanisms 3.

[0057] When stacking pallets, the pallet is conveyed to the bottom of the pallet rack 1 through the conveying assembly and is located above the pallet lifting mechanism 2. At this time, the pallet separating mechanism 3 lifts the pallet upward, specifically, the support plate 323 lifts the pallet stack; the pallet lifting mechanism 2 simultaneously or subsequently lifts the pallet located above it, so that the pallet rises to the bottom of the pallet stack, so that the pallet contacts or supports the pallet stack; at this time, the pallet supported by the two pallet separating mechanisms 3 is the second-to-last pallet, the two support plates 323 withdraw from the grooves on both sides of the second-to-last pallet, and the lifting plates 21 on the pallet lifting mechanism 2 temporarily support the pallet stack; the two support plates 323 fall back and partially extend into the grooves on both sides of the penultimate pallet, and the lifting plates 21 on the pallet lifting mechanism 2 fall back. At this point, the pallet conveyed to the top of the pallet lifting mechanism 2 has been stacked in the pallet stack.

[0058] When separating the trays, the lifting plate 21 on the tray lifting mechanism 2 lifts the tray stack, so that the tray stack is separated from the tray separating mechanism 3, and the support plates 323 on the tray separating mechanism 3 withdraw from the grooves; the lifting plates 21 on the tray lifting mechanism 2 move until the grooves on both sides of the second-to-last tray are aligned with the support plates 323 of the tray separating mechanism 3; the support plates 323 on the two tray separating mechanisms 3 move toward the grooves on both sides of the second-to-last tray until they partially extend into the grooves; the lifting plates 21 on the tray lifting mechanism 2 fall back and descend, and the penultimate tray descends accordingly, and is separated from the tray stack.

[0059] In this way, the pallet lifting mechanism 2 and the pallet separating mechanism 3 realize the stacking and placement of pallets by changing their positions and states, which facilitates the automatic placement and loading of pallets loaded with materials and the automatic recycling of empty pallets, enabling automatic loading and recycling of pallets, reducing the number of positions on the production line and lowering production costs.

[0060] For the disk dividing mechanism 3, if Figure 3 、 Figure 5 As shown, the tray separation mechanism 3 includes a tray separation lifting mechanism 31 and a movable support mechanism 32. The movable support mechanism 32 includes a support plate 323. The movable support mechanism 32 is arranged on the tray separation lifting mechanism 31 and is used to drive the support plate 323 to move telescopically toward the groove on the side of the tray. Two tray separation lifting mechanisms 31 are respectively arranged on both sides of the tray rack 1 to lift the movable support mechanism 32. The support plate 323 is a structure that directly contacts the tray. Specifically, the tray separation lifting mechanism 31 lifts the movable support mechanism 32, allowing the movable support mechanism 32 to move up and down. The movable support mechanism 32 drives the support plate 323 to move laterally. In this way, with the cooperation of the tray separation lifting mechanism 31 and the movable support mechanism 32, the support plate 323 can move up and down and move laterally.

[0061] Furthermore, if Figure 5 As shown, the tray separation mechanism 3 further includes a support frame 33, which is mounted on the tray separation lifting mechanism 31. The movable support mechanism 32 includes a drive element 321, a transmission member 322, a support plate 323, and a sliding mechanism 324. The sliding mechanism 324 is mounted on the support frame 33, and the support plate 323 is mounted on the sliding mechanism 324. The support plate 323 slides in a direction toward the groove on the side of the tray. The drive element 321 is mounted on the support frame 33 and connected to the transmission member 322. The transmission member 322 is connected to the support plate 323 to drive the support plate 323 to slide.

[0062] The support frame 33 is the transmission structure for lifting motion. The tray lifting mechanism 31 uses the support frame 33 to drive the mobile support mechanism 32 to move up and down. The support frame 33 also serves as the mounting structure for the mobile support mechanism 32. The drive element 321 and the sliding mechanism 324 are directly mounted on the support frame 33, and the support plate 323 is slidably mounted on the support frame 33 via the sliding mechanism 324.

[0063] For the support frame 33, as Figure 5 Specifically, the support frame 33 includes an upper plate, a lower plate, and a support column. The upper and lower plates are spaced apart, and the support column is disposed between the upper and lower plates, with each end of the support column connected to the upper and lower plates, respectively. A driving element 321 is disposed on the lower plate, a sliding mechanism 324 is disposed on the upper plate, and the tray lifting mechanism 31 is disposed below and connected to the lower plate. Within the support frame 33, the tray lifting mechanism 31 is connected to the lower plate, while the driving element 321 is mounted on the lower plate. The upper plate is used to mount the sliding mechanism 324 and the support plate 323. The installation of the support frame 33 facilitates the installation and arrangement of the mobile support mechanism 32, improving the convenience and efficiency of power transmission.

[0064] The sliding mechanism 324 specifically includes a slider and a guide rail. The guide rail is set on the upper plate, the slider is slidably set on the guide rail, and the support plate 323 is set on the slider.

[0065] In some embodiments of the tray device, such as Figure 2 、 Figure 3 As shown, in order to increase the pallet stacking speed and improve the accuracy of the movement of the pallet lifting mechanism 2 and the pallet separating mechanism 3, the pallet device also includes a first pallet stacking sensor 41 and a second pallet stacking sensor 42. The first pallet stacking sensor 41 is set at the lowest position of the pallet stack to control the lifting and lowering of the pallet lifting mechanism 2 and the pallet separating mechanism 3. The second pallet stacking sensor 42 is set at the highest position of the pallet stack to control the stacking height. The first pallet stacking sensor 41 and the second pallet stacking sensor 42 can be installed on the pallet rack 1 or on the guide member 12 described below.

[0066] When stacking trays, the tray is conveyed to the bottom of the tray rack 1 by the conveying assembly and is located above the tray lifting mechanism 2. At this time, the tray separating mechanism 3 lifts the tray upward, specifically, the support plate 323 lifts the tray stack until the first tray stacking sensor 41 loses the sensing signal to the tray. At this time, the tray stack is located above the lowest position; the tray lifting mechanism 2 simultaneously or subsequently lifts the tray above it, so that the tray rises to the bottom of the tray stack until the first tray stacking sensor 41 generates a sensing signal to the tray, so that the tray contacts or supports the tray stack; at this time, the trays supported by the two tray separating mechanisms 3 For the second-to-last pallet, the two support plates 323 withdraw from the grooves on both sides of the second-to-last pallet, and the lifting plates 21 on the pallet lifting mechanism 2 temporarily support the pallet stack; the tray separating mechanism 3 drives the support plates 323 to fall back below the bottom of the pallet stack, and the tray separating mechanism 3 drives the support plates 323 to move toward the direction of the groove of the penultimate pallet; the tray separating mechanism 3 drives the support plates 323 to move upward until the support plates 323 support the penultimate pallet, and the lifting plates 21 on the pallet lifting mechanism 2 fall back downward. At this point, the pallet transferred to the top of the pallet lifting mechanism 2 has been stacked in the pallet stack.

[0067] In this embodiment, the first stacking sensor 41 senses the disappearance and generation of the sensing signal, thereby sensing the position of the pallet, and accurately controlling the lifting distance of the pallet lifting mechanism 2 and the pallet separating mechanism 3 to ensure accurate pallet stacking.

[0068] Of course, when the tray separating mechanism 3 drives the support plate 323 to rise and support the last tray, it can also continue to lift up and rely on the disappearance and generation of the sensing signal of the first tray stacking sensor 41 to control the height of the support plate 323 after the trays are stacked.

[0069] When the second stack sensor 42 generates a sensing signal, it means that the stack has reached a predetermined height and the stack on the unloading tray rack 1 needs to be unloaded. The sensing signal generated by the second stack sensor 42 can trigger a stack overheight signal to alert the operator or control other stack unloading mechanisms to perform tray unloading.

[0070] In some embodiments of the tray device, such as Figure 4 As shown, in order to increase the tray separation speed and improve the movement accuracy of the tray lifting mechanism 2 and the tray separation mechanism 3, the tray device further includes a first tray drop sensor 43 and a second tray drop sensor 44.

[0071] The first tray drop sensor 43 is disposed at the lowest position of the tray stack and is used to control the lifting stop of the tray lifting mechanism 2. The second tray drop sensor 44 is disposed above the first tray drop sensor 43 and is used to sense the remaining amount of the tray.

[0072] When separating the trays, the lifting plate 21 on the tray lifting mechanism 2 lifts the tray stack until the first tray dropping sensor 43 loses the sensing signal to the tray, and the tray stack is separated from the tray separating mechanism 3, and the tray separating mechanism 3 drives the support plate 323 to retreat outward and exit the projection area of ​​the groove; the tray lifting mechanism 2 drives the lifting plate 21 to descend until the second tray dropping sensor 44 generates a sensing signal to the tray for the second time, at which time the lifting plate 21 descends by the height of two trays, and the grooves on both sides of the second-to-last tray are aligned with the support plates 323 of the tray separating mechanism 3; the support plates 323 on the two tray separating mechanisms 3 move toward the grooves on both sides of the second-to-last tray until they partially extend into the grooves; the lifting plate 21 on the tray lifting mechanism 2 falls back and descends, and the second-to-last tray descends accordingly and is separated from the tray stack, and the support plates 323 on the tray separating mechanism 3 support the tray stack again.

[0073] In this embodiment, the first tray placement sensor 43 senses the disappearance and generation of the sensing signal, thereby sensing the tray position and accurately controlling the lifting distance of the tray lifting mechanism 2 and the tray separating mechanism 3 to ensure accurate tray placement.

[0074] When the second tray drop sensor 44 loses its sensing signal for a pallet, it indicates that the tray stack has dropped to a predetermined height and that the number of pallets in the stack is insufficient, requiring a pallet drop. The sensing signal generated by the second tray drop sensor 44 can trigger a material shortage signal to alert the operator or control the tray stack loading mechanism to load the material.

[0075] In some further embodiments, Figure 4 As shown, the pallet device also includes a third pallet drop sensor 45, which is arranged below the pallet hole 13, specifically at the position where the conveying component receives the pallet, and is used to sense that the pallet is received by the conveying component, and at the same time control the subsequent stopping action of the pallet lifting mechanism 2.

[0076] In some embodiments of the pallet rack 1, such as Figure 3 、 Figure 4 As shown, the tray rack 1 is also provided with a plurality of guide members 12 arranged around the tray holes 13. More specifically, the number of guide members 12 is at least four. When four guide members 12 are provided, the guide members 12 are provided at positions corresponding to the four sides of the tray. When eight guide members 12 are provided, two guide members 12 are provided on both sides of the positions corresponding to each corner at the four corners of the tray. When twelve guide members 12 are provided, two guide members 12 are provided on both sides of the positions corresponding to each corner, and guide members 12 are provided at positions corresponding to the four sides of the tray. The guide members 12 guide the tray stack to be raised and lowered, preventing the tray stack from tipping over or vibrating and shifting.

[0077] In some embodiments of the pallet rack 1, such as Figure 3 、 Figure 4 As shown, tray rack 1 is provided with tray separation areas 14 on both sides for accommodating tray separation mechanism 3. These areas extend to tray access holes 13. The tray separation mechanism 3 is disposed within these areas. Providing these areas 14 on both sides of the tray rack 1 allows the tray separation mechanism 3 to be located within, or partially located within, the tray rack 1. This reduces the space occupied by the tray separation mechanism 3 and shortens the length of the support plate 323, thereby avoiding or minimizing bending deformation of the support plate 323 and improving the movement precision of the support plate 323 and the support precision of the tray separation mechanism 3.

[0078] Furthermore, the pallet rack 1 includes two sets of gantry structures 11 spaced apart and arranged side by side. The gap between the two gantry structures 11 forms a pallet partition 14. The gantry structures 11 include a horizontal plate and two support plates 323, which are respectively arranged at each end of the horizontal plate. The guide members 12 are provided on the gantry structures 11.

[0079] In some embodiments of the tray lifting mechanism 2, such as Figure 2 、 Figure 3 As shown, the tray lifting mechanism 2 includes a lifting plate 21, a mounting plate 22, a lifting element 23, a plurality of guide posts 24, and a connector 25. The mounting plate 22 is disposed below the lifting plate 21. The lifting element 23 is disposed on the mounting plate 22 and is connected to the lifting plate 21. The guide posts 24 are slidably disposed on the mounting plate 22, and the upper ends of the guide posts 24 are connected to the lifting plate 21. The connector 25 is located below the mounting plate 22 and is connected to the lower ends of the guide posts 24.

[0080] The lifting element 23 drives the lifting plate 21 to move up and down, and the guide column 24 guides the lifting plate 21 to move up and down accurately, thereby improving the lifting stability of the tray lifting mechanism 2. Specifically, the lifting element 23 can be an electric push rod or a pneumatic push rod.

[0081] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
