[0033] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0035] Reference Figures 1 to 6 As shown, a tray-laying device includes a first conveying device 1 and a second conveying device 2;

[0036] The first conveying device 1 includes a frame 11, on which a conveying unit 12 and a pallet release unit 13 are provided. The conveying unit 12 is provided with a material release station for placing pallet stacks. The conveying direction of the conveying unit 12 is a first direction.

[0037] The pallet release unit 13 is located on both sides of the unloading station. The pallet release unit 13 includes a limiting module 131 and a lifting module 132. The limiting module 131 is used to restrict the bottom first pallet from moving upward, and the lifting module 132 is used to lift all the bottom second and above pallets so that the bottom first pallet falls onto the conveying unit 12 alone.

[0038] Initially, the pallet stack is placed in the unloading station. The bottom pallet in the stack will contact the conveying unit 12. The bottom pallet is the first bottom pallet. The limiting module 131 restricts the first bottom pallet to prevent it from moving upward. At this time, the lifting module 132 lifts all the second bottom pallets and above. Then, the first bottom pallet is separated from the other pallets and remains alone on the conveying unit 12. The conveying unit 12 can then transport the individual pallet away from under the pallet stack. After that, the lifting module 132 lowers the pallet, and then the limiting module 131 resets. The pallet stack falls back onto the conveying unit 12, and the previous action is repeated to continue separating the pallets. In this way, the pallets can be separated one by one from the pallet stack.

[0039] The separated trays are transported by the conveying unit 12 and gradually pass through the predetermined area. The second conveying device 2 is used to transport the pastries and arrange them on the trays in the predetermined area.

[0040] In this embodiment, the specific structure of the second conveying device 2 can be referred to the second conveying device in patent 202210150548.9. By extending the length of the horizontal feeding section of the tray conveyor belt, the pastries can fall at different positions on the tray. This application will not elaborate on this.

[0041] The tray has multiple rows of recessed areas spaced along the first direction. When the conveying unit 12 conveys the tray, it does so intermittently. After a row of recessed areas enters the predetermined area, the conveying unit 12 stops conveying and allows the second conveying device 2 to arrange the pastries in that row of recessed areas within the predetermined area. After the arrangement is completed, the conveying unit 12 restarts and allows the next row of recessed areas to enter the predetermined area. The second conveying device 2 then starts arranging the pastries again, and so on, until all the recessed areas on the tray are filled with pastries.

[0042] In this embodiment, a guardrail 111 is provided on the frame 11. The guardrail 111 includes a rectangular frame 1111 and a plurality of support legs 1112. The rectangular frame 1111 is located above the conveying unit 12. The support legs 1112 connect the rectangular frame 1111 and the frame 11. The inner circle of the rectangular frame 1111 forms a feeding station.

[0043] The rectangular frame 1111 can be used to locate the approximate position of the pallet stack, which facilitates the arrangement of the pallet release unit 13; the support legs 1112 are connected to the corners of the rectangular frame 1111, which can stably support the rectangular frame 1111.

[0044] Meanwhile, the inner side of the rectangular frame 1111 is provided with multiple limiting rods 112, which are distributed around the pallet stack. The limiting rods 112 extend vertically. The outer contour of the pallet's projection on the horizontal plane is rectangular. Therefore, the outer contour of the pallet stack's projection on the horizontal plane is also rectangular. By providing limiting rods 112 around the pallet stack, the pallet stack can be restricted, keeping it in a vertical stacking posture and preventing it from tilting to one side.

[0045] The rectangular frame 1111 consists of four tubes, two of which are arranged at intervals along the first direction, and the other two are parallel to the first direction. Each tube corresponds to one side of the pallet stack, and each tube is fixed with at least one limiting rod 112.

[0046] Furthermore, the distance between the bottom of the limiting rod 112 and the conveying unit 12 is greater than the height of the pallet, ensuring that the limiting rod 112 will not affect the transportation of the bottom first pallet.

[0047] In this embodiment, there are four pallet release units 13, which are distributed around the material release station. That is, there is one pallet release unit 13 on each side of the pallet stack.

[0048] Specifically, the limiting module 131 includes a first cylinder 1311, a first connecting plate 1312 and a first insert 1313. The first cylinder 1311 is connected to the first connecting plate 1312 to drive the first connecting plate 1312 to move closer to or away from the pallet stack. The first insert 1313 is fixed on the first connecting plate 1312.

[0049] The lifting module 132 includes a second cylinder 1321 and a second insert 1322. The second cylinder 1321 is disposed on the first connecting plate 1312, and the second insert 1322 is connected to the second cylinder 1321. The second cylinder 1321 drives the second insert 1322 to rise and fall.

[0050] Initially, the pallet stack is placed in the unloading station. The bottom pallet in the stack contacts the conveying unit 12. The first cylinder 1311 actuates, causing the first insert 1313 and the second insert 1322 to approach the pallet stack, positioning them between the outer edges of the bottom first pallet and the bottom second pallet. Then, the second cylinder 1321 actuates, causing the second insert 1322 to lift all the bottom second and above pallets. The first insert 1313 can restrict the bottom first pallet from moving upward, thus separating it from the other pallets for raising or lowering. Once the bottom first pallet is off the bottom of the pallet stack, the second insert 1322 descends, bringing the pallet stack closer to the conveying unit 12. Then, the first cylinder 1311 resets, causing the first insert 1313 and the second insert 1322 to leave the pallet stack. At this point, the pallet stack falls back onto the conveying unit 12, and the separation process is repeated.

[0051] In practice, the first cylinder 1311 can be installed on the frame 11 or on the guardrail 111, depending on the actual situation.

[0052] In this embodiment, the first insert 1313 is disposed at one end of the first connecting plate 1312 near the feeding station, and there are at least two first inserts 1313 arranged at intervals in the horizontal direction.

[0053] The second cylinder 1321 is connected to the second connecting plate 1323. The second cylinder 1321 drives the second connecting plate 1323 to rise and fall. The second insert 1322 is fixed at the lower end of the second connecting plate 1323. There are at least two second inserts 1322, which are arranged at intervals in the horizontal direction.

[0054] The first insert 1313 and the second insert 1322 of the same tray release unit 13 are arranged alternately;

[0055] When the second insert 1322 descends to the lower limit, the second insert 1322 is flush with the first insert 1313. Therefore, when the second insert 1322 descends with the pallet stack, the second insert 1322 can descend to be flush with the first insert 1313. At this time, the pallet stack is closest to the conveying unit 12. The pallet stack then falls, and it is not easy to damage the pallet.

[0056] In this embodiment, the conveying unit 12 includes a conveyor belt 121 and a support plate 122 disposed on the frame 11. There are two support plates 122 located on both sides of the conveyor belt 121 along the first direction. The conveyor belt 121 moves the pallet, while the support plate 122 supports the pallet.

[0057] Preferably, the conveyor belt 121 is a conveyor belt 121 with baffles. The baffles are arranged at intervals on the belt of the conveyor belt 121 to prevent the pallet from slipping on the belt. The baffles can push the pallet to move.

[0058] In this embodiment, a transition conveyor belt 3, a discharge conveyor belt 4, and a first pushing device 5 are also included. The transition conveyor belt 3 is located between the conveying unit 12 and the discharge conveyor belt 4, and the first pushing device 5 is located above the transition conveyor belt 3.

[0059] The conveying unit 12 transports the trays filled with pastries to the transition conveyor belt 3, and the first pushing device 5 pushes the trays on the transition conveyor belt 3 to the discharge conveyor belt 4.

[0060] In this embodiment, the first pushing device 5 includes a lifting cylinder 51, a linear module 52 and a push plate 53. The push plate 53 is disposed at the output end of the linear module 52. The linear module 52 can drive the push plate 53 to move horizontally. The linear module 52 is connected to the output end of the lifting cylinder 51. The lifting cylinder 51 can drive the linear model to move up and down.

[0061] When the tray filled with pastries reaches the transition conveyor belt 3, the lifting cylinder 51 is activated, causing the linear module 52 to descend. Then, the linear module 52 runs, causing the push plate 53 to move horizontally and push the tray onto the discharge conveyor belt 4.

[0062] In this embodiment, a second pushing device 6 can be provided above the output end of the discharge conveyor belt 4 to push the pallet on the discharge conveyor belt 4 onto the packaging production line. The structure of the second pushing device 6 is the same as that of the first pushing device 5.

[0063] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
