Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to an automatic pallet conveying system. Background Technology

[0002] Currently, pallets are needed when loading products processed on the assembly line or transferring products to an automated warehouse or the next processing plant. However, the transfer and transportation of pallets are all carried out by forklifts one pallet at a time. This results in a heavy workload for forklift operators and requires multiple forklift operators to be specially assigned inside and outside the factory, leading to high labor intensity and high labor costs for workers.

[0003] Currently, palletized product loading and transfer in automated warehouses (AS / RS) are handled by forklifts on a per-pallet basis, requiring dedicated forklift operators. Currently, forklifts inside the factory (indoor forklifts) move the palletized products to the loading gate before they can be moved to other locations, such as warehouses or transport vehicles, by forklifts outside the factory (outdoor forklifts). During this process, the outdoor forklifts must wait for the indoor forklifts to smoothly lower the palletized products before they can move them, resulting in waiting time and reduced efficiency. Therefore, this invention proposes to design an automated conveyor system for outbound shipments from the workshop to improve forklift efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an automatic pallet conveying system.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses an automatic pallet conveying system, comprising a roller lifting mechanism, multiple chain conveying mechanisms, and multiple first roller conveying mechanisms. The multiple chain conveying mechanisms are connected end-to-end, with their tops at the same height to form a chain conveyor line located within the factory building. The multiple first roller conveying mechanisms are also connected end-to-end, with their tops at the same height and all higher than the chain conveying mechanisms, forming a roller conveyor line located within the factory building. The first end of each roller conveyor line is located at the end of the chain conveyor line, extending to the loading gate and forming an L-shape with the chain conveyor line. The roller lifting mechanism is located within one of the chain conveying mechanisms near the first roller conveyor mechanism and is used to lift the pallet and turn it. The end of the roller conveyor line is equipped with a forklift stop unit.

[0007] As a preferred embodiment of the present invention, the roller lifting mechanism includes a base, a lifting unit, and a second roller conveying mechanism. The second roller conveying mechanism is horizontally disposed above the base. The lifting unit is located between the base and the second roller conveying mechanism, and its two ends are fixedly connected to the base and the second roller conveying mechanism, respectively.

[0008] As a preferred embodiment of the present invention, a stop block is provided on one side of the top of the second roller conveyor mechanism.

[0009] As a preferred technical solution of this utility model, the forklift stop unit includes a support frame and a buffer block. The support frame is vertically installed on the ground outside the loading door and located below the tail end of the roller conveyor. The buffer block is located on the top of the support frame on the outward side.

[0010] As a preferred embodiment of this utility model, the number of chain conveying mechanisms is six, and the lengths of each are 3080mm, 1831mm, 3000mm, 3120mm, 3000.5mm and 3120mm respectively, and the height of each is 950mm.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] In the attached diagram, all identical reference numerals refer to the same components.

[0028] Example 1:

[0029] like Figure 1-2As shown, this utility model provides an automatic pallet conveying system, including a roller lifting mechanism 3, multiple chain conveying mechanisms 1, and multiple first roller conveying mechanisms 2. The multiple chain conveying mechanisms 1 are connected end to end, and the top of each is at the same height to form a chain conveyor line 4, which is located in the factory. The multiple first roller conveying mechanisms 2 are connected end to end, and the top of each is at the same height, and all are higher than the height of the chain conveying mechanisms 1 to form a roller conveyor line 5, which is also located in the factory. The first end of the roller conveyor line 5 is located at the tail end of the chain conveyor line 4, and its tail end extends to the loading door and forms an L-shape arrangement with the chain conveyor line 4. The roller lifting mechanism 3 is located in one of the chain conveying mechanisms 1 near the first roller conveyor mechanism 2, and is used to lift the pallet and turn the pallet.

[0030] Specifically, inside the factory, an in-field forklift (manually driven forklift or AGV forklift) transfers a pallet loaded with goods to the beginning of the chain conveyor line 4. Multiple chain conveyor mechanisms 1 then transfer the pallet to a roller lifting mechanism 3. The roller lifting mechanism 3 then lifts the pallet and transfers it to a roller conveyor line 5 via a roller conveyor mechanism. Multiple first roller conveyor mechanisms 2 then transfer the pallet to the loading gate. An out-of-field forklift raises its forks slightly above the height of the first roller conveyor mechanisms 2 and moves towards them to place the forks on the first roller conveyor mechanisms 2, inserting the forks under the pallet. The out-of-field forklift then raises its forks again to transfer the pallet from the first roller conveyor mechanisms 2. Finally, the out-of-field forklift's forks are reset, and the pallet is moved to the warehouse or transport vehicle.

[0031] Example 2:

[0032] like Figure 1 , 2 As shown in Figure 5, there are six chain conveyor mechanisms 1, and the lengths of each are 3080mm, 1831mm, 3000mm, 3120mm, 3000.5mm and 3120mm respectively, and the height of each is 950mm.

[0033] Specifically, each chain conveyor 1 has two parallel and spaced conveyor chains that drive the pallet to move. The chain conveyor 1 is divided into two types with different conveyor chain spacings. The spacing between the two conveyor chains of the first chain conveyor 1 is smaller than the spacing between the two chains of the next chain conveyor 1, and so on (3 narrow and 2 wide).

[0034] Furthermore, the tail ends of the two conveyor chains of the preceding chain conveyor mechanism 1 extend 20-100mm into the head ends of the two conveyor chains of the following chain conveyor mechanism 1 to achieve a better pallet conveying effect.

[0035] The quantity, length, height, and width of the chain conveyor mechanism 1 can be modified according to actual needs.

[0036] Example 3:

[0037] like Figure 1 , 2 As shown in Figure 4, there are two first roller conveyor mechanisms 2, and the width of the rollers of both is 1020mm. The length of one first roller conveyor mechanism 2 closer to the chain conveyor mechanism 1 is 500mm and the height is 985mm, while the length of the other first roller conveyor mechanism 2 is 1500mm and the height is 1405mm.

[0038] Specifically, because the automated conveying system is L-shaped, the pallet needs to be turned during the pallet transfer process, requiring the first roller conveyor 2 to be higher than the chain conveyor 1. In this embodiment, a lifting mechanism with a roller conveyor at the top is used to lift the pallet. After being lifted, the pallet leaves the chain conveyor 1 and therefore no longer moves in the conveying direction of the chain conveyor 1. The pallet is lifted to be level with the first roller conveyor 2, and then transferred to the first roller conveyor 2 by the roller conveyor on the lifting mechanism, thus enabling the pallet to be transferred out of the loading door.

[0039] One of the first roller conveyors 2, which is close to the chain conveyor 1, is located inside the factory building and therefore has a height of 985 mm. The other first roller conveyor 2 is located on the ground outside the factory building and therefore has a height of 1405 mm to compensate for the height difference.

[0040] The quantity, length, height, and width of the first roller conveyor mechanism 2 can be modified according to actual needs.

[0041] Example 4:

[0042] like Figure 1-3 As shown, the roller lifting mechanism 3 includes a base 31, a lifting unit 32, and a second roller conveying mechanism 33. The second roller conveying mechanism 33 is horizontally disposed above the base 31. The lifting unit 32 is located between the base 31 and the second roller conveying mechanism 33, and its two ends are fixedly connected to the base 31 and the second roller conveying mechanism 33, respectively.

[0043] Furthermore, the second roller conveyor 33 has a length of 924 mm and a roller width of 1020 mm.

[0044] Specifically, the lifting unit 32 is a servo lifting machine using existing technology, with a lifting range of 910-990mm. The second roller conveyor mechanism 33 is raised by the lifting unit 32 located at the top of the base 31, thereby raising the pallet and separating it from the chain conveyor mechanism 1.

[0045] Example 5:

[0046] like Figure 1-3 As shown, a stop 34 is provided on one side of the top of the second roller conveyor mechanism 33.

[0047] Specifically, the stop 34 is located on the side of the second roller conveyor 33 away from the pallet loading end, and the stop 34 is used to prevent the pallet from rushing out of the lifting range due to inertia.

[0048] Example 6

[0049] like Figure 2 , 5 As shown in Figures 6 and 7, the tail end of the roller conveyor line 5 is equipped with a forklift stop unit 6.

[0050] Furthermore, the forklift stop unit 6 includes a support frame 61 and a buffer block 62. The support frame 61 is vertically mounted on the ground outside the loading door and located below the tail end of the roller conveyor line 5. The buffer block 62 is located on the top of the support frame 61 on the outward side.

[0051] Furthermore, the support frame 61 has a length of 1000mm, a height of 350mm, and a cross-section of a right triangle with a base width of 200mm. The buffer block 62 has a thickness of 100mm.

[0052] Specifically, the forklift stop unit 6 can serve as a stopping reminder when the forklift in the field picks up the pallet, and can also prevent the forklift in the field from colliding with the first roller conveyor mechanism 2 due to insufficient stopping time.

[0053] The support frame 61 with a right-angled triangle cross section has good stability. The buffer block 62 can be made of rubber and is used to buffer when it collides with the forklift vehicle in the field. The length of the support frame 61 is similar to the width of the first roller conveyor mechanism 2, and the setting height of the buffer block 62 is similar to the radius of the forklift wheel in the field.

[0054] Example 7:

[0055] like Figure 1 , 2 As shown in Figures 4 and 5, each chain conveyor 1 and each first roller conveyor 2 are provided with baffles 7 on both sides for limiting the position of the pallet.

[0056] Specifically, baffle 7 is used to prevent the pallet from shifting during the conveying process, and baffle 7 is not provided on the loading side of the first chain conveyor mechanism 1.

[0057] In the above embodiments, the chain conveyor mechanism 1 is driven by a Taibang three-phase 0.75KW horizontal motor (model CH750-30S-G3-TB-T1, horizontally installed, output shaft diameter Φ32), and the first roller conveyor mechanism 2 and the second roller conveyor mechanism 33 are driven by a Taibang three-phase 0.75KW horizontal motor (model CH750-30S-G2-RD-T6, horizontally installed, output shaft diameter Φ32).

[0058] The automatic pallet conveying system in this application is controlled by a controller (not shown in the figure, but may be a PLC controller). The chain conveying mechanism 1, which is equipped with a roller lifting mechanism 3, is equipped with a photoelectric switch (which may be an Omron SPZ301) with its output end facing vertically upward. This switch is used to detect whether there is a pallet on the second roller conveying mechanism 33. If a pallet is detected, the controller controls the lifting unit 32 to rise to a suitable position so that the second roller conveying mechanism 33 can send the pallet to the first roller conveying mechanism 2.

[0059] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
