[0002] A pallet, also known as a tray, can be used to hold larger quantities of materials for feeding, thereby improving material loading efficiency. During the process of collecting materials after they have been loaded or when the pallet is empty, automatic transfer and stacking can improve automation and efficiency, reducing the frequency of manual operation.
[0003] In the prior art, such as the automatic pallet loading and unloading machine with application number 202022530024.1, the loading lifting station, the unloading lifting station, the operating station and the handling mechanism are disclosed. After the material on the pallet is removed, the station that finally realizes pallet stacking is the unloading lifting station. As the number of pallets stacked increases, the unloading lifting station gradually moves down to match the height of the pallets after stacking. During the stacking process, the unloading lifting station needs to match the height of the pallets in real time through a set program. Utility Model Content
[0004] The purpose of this utility model is to provide a pallet transfer structure that, through the cooperation of various components, enables the pallet to be moved horizontally, lifted, moved in the opposite direction after removal, and stacked, thereby facilitating the subsequent handling of entire pallets and optimizing the process.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a pallet transfer structure, comprising:
[0006] Install the framework.
[0007] A pallet loading line, which is installed on the mounting frame, is used for pallet loading.
[0008] A pallet unloading line, which is mounted on the mounting frame and located above the pallet loading line, is used for pallet unloading.
[0009] The transfer mechanism includes a lifting assembly mounted on the mounting frame and a carrying assembly mounted on the lifting assembly. The carrying assembly is driven to be located at the end of the pallet loading line to carry pallets, and is also driven to rise to be located beside the pallet unloading line.

[0011] A stacking mechanism includes at least a pair of lifting components symmetrically arranged on opposite sides of the end of the pallet unloading line. The lifting components include a lifting cylinder, a translation cylinder, and a top plate. The lifting cylinder is disposed on the mounting frame and has a translation cylinder at its output end. The top plate is disposed at the output end of the translation cylinder and is driven to lift the pallet away from the pallet unloading line.
[0012] As a further optimization, the pallet feeding line is a belt feeding line, and the bearing component includes a mounting plate and a support. The mounting plate is disposed on the lifting component, and the support is disposed on the mounting plate for bearing the pallet. The vertical projection of the support does not coincide with the vertical projection of the belt of the pallet feeding line.
[0013] As a further optimization, the support includes multiple spaced-apart support plates, and stiffeners are provided between the support plates and the mounting plate to ensure the structural stability of the support.
[0014] As a further optimization, the lifting assembly includes a first drive motor, a first transmission part, and a lead screw and nut pair. The first transmission part is disposed at the output end of the first drive motor, the lead screw and nut pair is disposed on the mounting frame and connected to the first transmission part, and the bearing assembly is connected to the lead screw and nut pair.
[0015] As a further optimization, the material transfer mechanism includes a translation component, a lifting cylinder, and a vacuum adsorption component.

[0018] As a further optimization, the mounting frame is provided with a vertical plate above the middle of the pallet unloading line, which can work in conjunction with the baffle to ensure the stability of the stacked pallets in the vertical direction.
[0019] As a further optimization, the pallet transfer structure also includes a positioning mechanism, which includes at least a pair of positioning cylinders disposed on the mounting frame and located beside the pallet unloading line. The output end of the positioning cylinder is provided with a positioning baffle.

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0032] like Figures 1 to 5 As shown, a pallet transfer structure includes a mounting frame 10, a pallet loading line 20, a pallet unloading line 30, a transfer mechanism 40, a material transfer mechanism 50, and a stacking mechanism 60. The pallet loading line 20 is disposed on the mounting frame 10 for pallet loading, and the pallet unloading line 30 is disposed on the mounting frame 10 and located above the pallet loading line 20 for pallet unloading. The transfer mechanism 40 includes a lifting component 41 disposed on the mounting frame 10 and a carrying component 42 disposed on the lifting component 41. The carrying component 42 is driven to be located at the end of the pallet loading line 20 for carrying pallets, and is driven... The lifting mechanism is located on the side of the beginning of the pallet unloading line 30. The material transfer mechanism 50 is set on the mounting frame 10 to transfer the pallet on the carrying component 42 to the pallet unloading line 30. The stacking mechanism 60 includes at least a pair of lifting components 61 symmetrically arranged on opposite sides of the end of the pallet unloading line 30. The lifting component 61 includes a lifting cylinder 611, a translation cylinder 612 and a top plate 613. The lifting cylinder 611 is set on the mounting frame 10 and the output end is provided with the translation cylinder 612. The top plate 613 is set at the output end of the translation cylinder 612 and is driven to lift the pallet away from the pallet unloading line 30.
[0033] In this invention, pallet 1001 is fed individually on pallet feeding line 20. When pallet 1001 moves to the end of pallet feeding line 20, the supporting component 42 moves upward under the drive of lifting component 41 and abuts against the lower end of pallet 1001, moving pallet 1001 upward to the side of the beginning of pallet unloading line 30. The transferring mechanism 50 transfers pallet 1001 from the supporting component 42 to the pallet unloading line 30, so that... Pallet 1001 is fed on pallet unloading line 30. When pallet 1001 moves to the end of pallet unloading line 30, translation cylinder 612 drives at least a portion of top plate 613 to be located at the lower end of pallet 1001. Then, lifting cylinder 611 drives translation cylinder 612 and top plate 613 to move upward, so that top plate 613 abuts against the lower end of pallet 1001, detaching pallet 1001 from pallet unloading line 30 and placing it at a certain position. The height is maintained; when another pallet 1001 is conveyed to the end of the pallet unloading line 30, the lifting cylinder 611 drives the translation cylinder 612, the top plate 613, and the pallet located on the top plate 613 to descend. After the translation cylinder 613 drives the top plate 613 to translate away from the pallet 1001 (no longer supporting the pallet), the pallet is stacked with the pallet located on the pallet unloading line 30. The lifting cylinder 611 drives the translation cylinder 612 and the top plate 613 to move down so that the upper end surface of the top plate 613 is lower than the lower end surface of the pallet located on the pallet unloading line 30. Then the translation cylinder 612 drives at least part of the top plate 613 to be located at the lower end of the pallet on the pallet unloading line 30. Then the lifting cylinder 611 drives the translation cylinder 612 and the top plate 613 to move up, thereby lifting the stacked pallets upward. In this way, multiple pallets 1001 are stacked one by one to form a stacked pallet 1002. Preferably, the structure of the pallet 1001 is an isosceles trapezoid, that is, the lower end of the side of the pallet 1001 near the lifting component 61 is wider than its upper end. The part of the lower end that is wider than the upper end can be used to contact the top plate 613. When stacking, it can ensure that the lowermost pallet on the top plate 613 is stably abutted against the upper end of the pallet on the pallet unloading line 30.
[0034] It should be noted that this utility model can feed and stack empty pallets 1001, and can also stack pallets carrying products. In this case, the products on the pallet need to be removed by external equipment before the pallet 1001 is fed to the pallet unloading line 30 by the material transfer mechanism 50.
[0035] This utility model can realize the automatic feeding and stacking of pallets 1001, that is, the pallet can be moved horizontally, lifted, moved in the opposite direction after removal, and stacked. The pallet loading and unloading is realized in a small space, and the automatic stacking action can realize the subsequent handling of the whole stack of pallets without the need for frequent operation of the pallet to leave the device, which is more conducive to the optimization of the process.
[0036] Combination Figure 6 and Figure 7 As shown, preferably, the pallet feeding line 20 is a belt feeding line. The carrying component 42 includes a mounting plate 421 and a support portion 422. The mounting plate 421 is disposed on the lifting component 41, and the support portion 422 is disposed on the mounting plate 421 to carry the pallet 1001. The vertical projection of the support portion 422 does not coincide with the vertical projection of the belt of the pallet feeding line 20, so that the support portion 422 can be moved down and located inside the end of the pallet feeding line 20, so that the pallet 1001 fed to the end of the pallet feeding line 20 is located above the support portion 422.
[0037] Furthermore, the support portion 422 includes a plurality of pallets 4221 spaced apart from each other, and gaps 4220 are formed between adjacent pallets 4221 to allow the belt in the pallet loading line 20 to pass through upward or downward; stiffening plates 4222 are provided between the pallets 4221 and the mounting plate 421 to ensure the stability of the pallets 4221 and the structural strength of the support portion 422.
[0038] Preferably, the lifting assembly 41 includes a first drive motor 411, a first transmission part 412, and a lead screw and nut pair 413. The first transmission part 412 is a combination structure of a transmission wheel and a belt, which is located at the output end of the first drive motor 411. The lead screw and nut pair 413 is located on the mounting frame 10 and connected to the first transmission part 412. The mounting plate 421 in the bearing assembly 42 is located on the lead screw nut in the lead screw and nut pair 413, and the two sides of the mounting plate 421 are respectively sleeved on the guide rods 414 on the mounting frame 10. The first drive motor 411 drives the lead screw and nut pair 413 to move through the first transmission part 412. Under the rotation of the lead screw, the lead screw nut moves up and down, thereby driving the mounting plate 421 and the support part 422 to move up and down.
[0039] The material transfer mechanism 50 specifically includes a translation component 51, a lifting cylinder 52, and a vacuum adsorption component 53. The translation component 51 is mounted on the mounting frame 10, the lifting cylinder 52 is mounted on the translation component 51, and the vacuum adsorption component 53 can be a pair of vacuum nozzles, which are located at the lower end of the lifting cylinder 52 for adsorbing the tray 1001. When the lifting cylinder 52 drives the vacuum adsorption component 53 to move down and adsorb the tray 1001 located on the bearing component 42, the translation component 51 drives the tray 1001 to move horizontally above the tray unloading line 30, and the lifting cylinder 52 drives the vacuum adsorption component 53 to place the tray 1001 on the tray unloading line 30.
[0040] Specifically, the translation component 51 includes a second drive motor 511, a second transmission part 512, and a vertical plate 513. The second transmission part 512 is a combination structure of a transmission wheel and a belt. The vertical plate 513 is slidably mounted on the mounting frame 10 via a guide rail pair 514. The second transmission part 52 is connected to the second drive motor 511 and the vertical plate 513 respectively. That is, the drive wheel in the transmission wheel of the second transmission part 52 is connected to the second drive motor 511, and the belt in the second transmission part 52 is connected to the clamping plate 5131 on the vertical plate 513. The vertical plate 513 and the lifting cylinder 52 located on the vertical plate 513 can be driven to translate by the action of the second drive motor 511.
[0041] For example Figure 4 and Figure 5 As shown, the stacking assembly 60 also includes a pair of crossbar assemblies 62. The crossbar assembly 62 includes a drive cylinder 621 and a baffle 622. The drive cylinder 621 is symmetrically arranged on the mounting frame 10, and the baffle 622 is arranged at the output end of the drive cylinder 621. When the lifting assembly 61 performs the stacking action of the pallets 1001, the drive cylinder 621 drives the baffle 622 to extend, which can prevent the stacked pallets 1002 from tilting to one side.
[0042] Combined Figure 2 As shown, an upright plate 11 is provided on the mounting frame 10 above the middle of the pallet unloading line 30. The upright plate 11 and the baffle 622 cooperate to keep the stacked pallet 1002 in a stable state.
[0043] For example Figure 6 and Figure 7 As shown, the pallet transfer structure also includes a positioning mechanism 70. The positioning mechanism 70 includes at least a pair of positioning cylinders 71 disposed on the mounting frame 10 and located beside the pallet unloading line 30. The output end of the positioning cylinder 71 is provided with a positioning baffle 72. After being driven to move, the positioning baffle 72 abuts against the upper end of the pallet 1001 located on the bearing component 42. The positioning baffle 72 can limit the height at which the pallet 1001 is lifted and ensure its stability before being transferred by the material transfer mechanism 50.
[0044] In addition, such as Figure 4As shown, both the pallet loading line 20 and the pallet unloading line 30 are equipped with baffles 32. The baffles 32 can block the loading or unloading pallets 1001 at intervals, ensuring that the pallets 1001 are fed in an orderly manner. In addition, a support plate 31 is provided on the pallet unloading line 30 below its belt. The support plate 31 is mainly located below the pallet stacking area. When the stacked pallets supported by the top plate 613 are placed on the pallets at the end of the pallet unloading line 30, the stacked pallets 1002 have a large weight. The belt alone cannot provide effective support. The belt is pressed down and abuts against the support plate 31, which not only makes the belt only slightly deformed, but also provides effective support for the stacked pallets 1002 before they are lifted again by the top plate 613.
[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
