Description

Technical Field

[0001] This utility model relates to the field of pallet manufacturing, and in particular to a multi-adaptive pallet unloading machine. Background Technology

[0002] During the production process, stacked pallets need to be split, which is usually done manually, resulting in low efficiency. Currently, the splitting structure of existing pallet machines on the market all use a rotary fork, which can be inserted horizontally or vertically, but the insertion depth is shallow. If the pallet has reinforcing ribs on the edge of the fork opening, it can work normally. However, for pallets with reinforcing ribs located deep inside the pallet opening, the pallet will deform severely during operation and cannot be supported by the fork. Therefore, this solution proposes a multi-adaptive pallet splitting machine. Utility Model Content

[0003] This utility model proposes a multi-adaptive pallet unloading machine, which solves the problem that existing pallet unloading machines cannot effectively unload pallets with reinforcing ribs in different positions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-adaptive pallet unloading machine includes a pallet unloading machine frame, which comprises an extension frame and a base frame fixed to the top of the extension frame. A lifting mechanism is installed on the base frame, and a pallet detection photoelectric device, an upper and lower limit adjustment photoelectric device, and four adjustable forks are installed on the extension frame and connected to the lifting mechanism.

[0006] The four adjustable forks are symmetrically distributed in pairs on both sides of the base frame. The pallet detection photoelectric device includes a mounting plate fixed on the lifting frame and a detection photoelectric device mounted on the mounting plate. The upper and lower limit adjustment photoelectric device is located in front of the lifting mechanism on the left and is used to cooperate with the lifting mechanism to complete the lowering and transportation of the pallet. The upper and lower limit adjustment photoelectric device includes a photoelectric detection plate fixed on the lifting frame and a photoelectric sensor mounted on the photoelectric detection plate.

[0007] The above technical solution enables the disassembly and placement of different pallets by adjusting the extension distance of the adjustable fork, thereby firmly supporting the pallet and adapting to the different reinforcing rib positions of different pallets on the market.

[0008] As a further improvement to the above solution, the basic frame has openings at the front and top, and the top opening of the basic frame opens to both sides.

[0009] The above technical solution allows the opening to open outwards, making it easier for the pallet to be placed inside the base frame from the opening.

[0010] As a further improvement to the above solution, the adjustable shift fork includes a housing fixed to the base frame, a cylinder disposed inside the housing, and a horizontal shift fork fixed to the output end of the cylinder.

[0011] As a further improvement to the above solution, an anti-slip pad is fixed to the front end of the top surface of the horizontal shift fork.

[0012] As a further improvement to the above solution, the lifting mechanism is located at the center of the base frame, and the lifting mechanism includes a lifting cylinder installed inside the lifting frame and a tray fixed to the output end of the lifting cylinder. The bottom surface of the tray is hinged with multiple folding frames, and the other end of each of the multiple folding frames is hinged to the bottom of the lifting frame.

[0013] As a further improvement to the above solution, both the mounting plate and the upper and lower limit adjustment photoelectric device are located on one side of the heightening frame, and the mounting plate is located above the upper and lower limit adjustment photoelectric device.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By adjusting the extension distance of the fork, it is possible to disassemble and place different pallets. In the lateral direction, the fork can extend horizontally according to the location of the reinforcing rib, thus ensuring that the length is sufficient to extend below the unique reinforcing rib of the pallet, thereby firmly supporting the pallet and adapting to the different reinforcing rib positions of different pallets on the market.

[0016] 2. By installing anti-slip pads on the top surface of the horizontal fork, the friction between the tray and the horizontal wave fork can be further increased, preventing the tray from sliding during movement. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figure 1 - Figure 4 This embodiment of a multi-adaptive pallet unloading machine includes a pallet unloading machine frame 1. The pallet unloading machine frame 1 consists of an extension frame and a base frame 1-1 fixed on top of the extension frame 1-2. The base frame 1-1 has openings at the front and top, and the top opening of the base frame 1-1 opens to both sides to expand the opening, thereby facilitating the guidance of the pallet and making it easier to place it inside the base frame 1-1.

[0026] A lifting mechanism 3 is installed on the base frame 1-1. The lifting mechanism 3 is located at the center of the base frame 1-1. The lifting mechanism 3 includes a lifting cylinder 3-1 installed inside the heightening frame 1-2 and a tray support 3-2 fixed to the output end of the lifting cylinder 3-1. Multiple folding frames 3-3 are hinged to the bottom surface of the tray support 3-2, and the other end of each folding frame 3-3 is hinged to the bottom of the heightening frame 1-2. The lifting and lowering of the tray support 3-2 is adjusted by the extension and retraction of the lifting cylinder 3-1. The folding frames 3-3 can further stabilize the tray support 3-2 and prevent it from swaying in the left, right and front and back directions during the lifting and lowering process.

[0027] The lifting frame 1-2 is equipped with a tray detection photoelectric sensor 4 connected to the lifting mechanism 3, an upper and lower limit adjustment photoelectric device 5, and four adjustable forks 2;

[0028] Four adjustable shift forks 2 are symmetrically distributed in pairs on both sides of the base frame 1-1. Each adjustable shift fork 2 includes a housing fixed on the base frame 1-1, a cylinder 2-1 set inside the housing, and a horizontal shift fork 2-2 fixed at the output end of the cylinder 2-1. During operation, the stroke of the cylinder 2-1 is controlled by a photoelectric signal. The stroke of the cylinder 2-1 determines the length of the horizontal shift fork 2-1, thereby determining whether it can adapt to the position of different reinforcing ribs.

[0029] The pallet detection photoelectric sensor 4 includes a mounting plate 4-1 fixed on the lifting frame 1-2 and a detection photoelectric sensor 4-2 mounted on the mounting plate 4-1. When the detection photoelectric sensor 4-2 is working, it can detect whether there is a pallet on the pallet holder 3-2, and then feed the signal back to the lifting mechanism 3, thereby driving the lifting cylinder 3-1 to extend or retract.

[0030] The upper and lower limit adjustment photoelectric device 5 is located in front of the left side of the lifting mechanism 3 and is used to cooperate with the lifting mechanism 3 to complete the lowering and transportation of the pallet. The upper and lower limit adjustment photoelectric device 5 includes a photoelectric detection plate 5-2 fixed on the heightening frame 1-2 and a photoelectric sensor 5-1 installed on the photoelectric detection plate 5-2. The photoelectric detection plate 5-2 is connected to the lifting cylinder 3-1. The two work together to complete the lowering and transportation of the pallet.

[0031] The implementation principle of this embodiment is as follows: During operation, the lifting cylinder 3-1 of the lifting mechanism 3 is in the forward position, and the cylinder 2-1 of the adjustable fork 2 is in the forward position. After all pallets enter the pallet unloading machine and are stacked inside the base frame 1-1 of the pallet unloading machine frame 1, the return stroke of the lifting cylinder 3-1 is adjusted according to the set program so that the horizontal fork 2-2 of the adjustable fork 2 can be horizontally inserted into the fork opening of the pallet above the pallet that is in contact with the pallet holder 3-2 after the cylinder 2-1 returns. Furthermore, it is ensured that the horizontal fork 2-2 can extend beyond the location of the reinforcing rib of the pallet, thereby ensuring that the pallet will not deform due to the weight of the pallet above. After successful insertion, a feedback signal is sent to the lifting cylinder 3-1. The lifting cylinder 3-1 returns to control the tray to descend, and at the same time, it moves the photoelectric detection plate 5-2 down. After a certain distance, the photoelectric detection plate 5-2 sends a feedback signal to the lifting cylinder 3-1 to stop its return and keep it stationary so that the conveyor below can smoothly transport the tray. When the tray detection photoelectric 4 detects that there is no tray on the tray holder 3-2, it sends a feedback signal to the lifting mechanism 3, and enters the next step of the operation. The lifting cylinder 3-1 continues to move until the photoelectric detection plate 5-2 sends a feedback signal to the lifting cylinder 3-1 to control its movement to stop. At this time, the tray holder 3-2 comes into contact with the tray, and thus, the process of removing and placing a tray is completed.

[0032] Example 2:

[0033] Combination Figure 2 The further improvement of this embodiment based on embodiment 1 is that an anti-slip pad 2-3 is fixed to the front end of the top surface of the horizontal shift fork 2-2.

[0034] The implementation principle of this embodiment is as follows: after the horizontal fork 2-2 is successfully inserted under the tray, the anti-slip pad 2-3 contacts the bottom surface of the tray, so that the tray will not easily slide between the horizontal fork 2-2, thus ensuring the stability of the tray during movement.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
