[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0034] Referring to Figures 1 and 2, in one embodiment of this utility model, an automatic tray retrieval and placement buffer device is disclosed, comprising:

[0035] A buffer cart 1 is used to store multiple trays, and the buffer cart 1 is provided with guide wheels 13 on its side;

[0036] The frame 2 has a storage chamber 22 and multiple side plates 21. The multiple side plates 21 are symmetrically arranged on both sides of the storage chamber 22. Each side plate 21 has a guide slope 21b. The distance between the guide slopes 21b on both sides of the storage chamber 22 gradually decreases along the moving direction of the buffer trolley 1.

[0037] The lifting and conveying mechanism 3 is connected to the buffer trolley 1, and the lifting and conveying mechanism 3 is used to lift and convey the tray to the storage chamber 22.

[0038] Locking mechanism 4 is used to lock the frame 2 and the buffer trolley 1.

[0039] The automatic pallet retrieval and buffer device described in this embodiment uses a buffer trolley 1 to store multiple pallets. The buffer trolley 1 can be flexibly moved to different workstations, improving pallet handling efficiency. When the buffer trolley 1 is pushed into the storage chamber 22, the guide wheels 13 on both sides and the guide ramp 21b work together to precisely guide the buffer trolley 1, ensuring that the buffer trolley 1 moves along the center of the storage chamber 22 and accurately connects with the lifting and conveying mechanism 3. Then, the lifting and conveying mechanism 3 completes the pallet input and output, improving the pallet buffering and retrieval efficiency. The locking mechanism 4 automatically locks the buffer trolley 1 to the frame 2, preventing the buffer trolley 1 from moving around in the storage chamber 22 and ensuring the success rate of the automatic input and output of the lifting and conveying mechanism 3.

[0040] Referring to FIG3, in one embodiment of the present invention, the bottom of the buffer trolley 1 is equipped with multiple rollers 11 so as to flexibly move the buffer trolley 1 to different work areas.

[0041] Referring to Figures 2 and 6, in one embodiment of the present invention, the two side plates 21 are symmetrically arranged on both sides of the storage chamber 22.

[0042] Referring to Figures 2 and 6, in one embodiment of this utility model, the guide ramps 21b on both sides adopt a tapered design. The guide ramps 21b have an angle with the moving direction. It can be understood that the guide ramps 21b on both sides of the storage chamber 22 are directly opposite each other, and the distance between the guide ramps 21b on both sides gradually decreases towards the inside of the storage chamber 22 along the moving direction of the buffer cart 1. The guide ramps 21b on both sides can gradually correct the positional deviation of the buffer cart 1 during the process of pushing the buffer cart 1 in, so as to realize the automatic centering of the buffer cart 1. The rolling friction of the guide wheel 13 reduces resistance and improves the smoothness of the movement of the buffer cart 1.

[0043] Referring to FIG5, in one embodiment of the present invention, the locking mechanism 4 includes a driver and a pin 41. When the buffer trolley 1 is pushed to the preset position of the storage chamber 22, the pin 41 is aligned with the positioning hole 121 of the buffer trolley 1. The driver drives the pin 41 to insert into the positioning hole 121 of the buffer trolley 1, restricting the buffer trolley 1 from moving in the moving direction, thereby locking the buffer trolley 1 with the frame 2. The driver is preferably a cylinder.

[0044] Referring to FIG5, in one embodiment of the present invention, the locking mechanism 4 further includes a fixed base 43 and a buffer block 44 connected to the fixed base 43. The fixed base 43 is connected to the output end 42 of the driver, and the pin 41 is connected to the fixed base 43. When the pin 41 is inserted into the positioning hole 121, the buffer block 44 presses against the frame 2 to absorb the impact force when the driver is activated, preventing the fixed base 43 from damaging the frame 2.

[0045] In one embodiment of this utility model, the buffer block 44 is preferably made of polyurethane.

[0046] In one embodiment of the present invention, the positioning holes 121 are provided on both sides of the buffer carriage 1 so that the pin 41 can lock the buffer carriage 1 on both sides. The positioning holes 121 are located at the rear of the buffer carriage 1 so that the locking mechanism 4 can lock the rear of the buffer carriage 1 and reduce the shaking of the rear of the buffer carriage 1.

[0047] Referring to FIG2, in one embodiment of the present invention, two locking mechanisms 4 are respectively disposed on both sides of the storage chamber 22 for locking the positioning holes 121 on both sides of the buffer trolley 1.

[0048] Referring to Figure 6, in one embodiment of this utility model, the side plate 21 is further provided with a limiting plane 21a. The limiting plane 21a is parallel to the moving direction of the buffer trolley 1, and the limiting plane 21a is connected to the end of the guide slope 21b along the moving direction. During the process of the buffer trolley 1 entering the storage chamber 22, the guide wheel 13 first slides on the guide slope 21b to gradually correct the position deviation of the buffer trolley 1. When the guide wheel 13 rolls to the end of the guide slope 21b, the buffer trolley 1 slides past the limiting plane 21a, completing the position deviation correction of the buffer trolley 1. When the buffer trolley 1 is stationary in the storage chamber 22, the limiting plane 21a abuts against the guide wheel 13 of the buffer trolley 1 to prevent the buffer trolley 1 from swaying laterally.

[0049] Referring to FIG3, in one embodiment of the present invention, the buffer cart 1 is provided with guide wheels 13 on both sides, the guide wheels 13 on both sides correspond to the limiting planes 21a on both sides respectively, and the guide wheels 13 are disposed at the head of the buffer cart 1, and the limiting planes 21a abut against the guide wheels 13 to limit the head of the buffer cart 1 laterally.

[0050] Referring to FIG1, in one embodiment of the present invention, a limiting plate 5 is further provided in the storage chamber 22. The limiting plate 5 abuts against the buffer trolley 1 located in the storage chamber 22 along the moving direction. When the buffer trolley 1 moves to a certain position in the storage chamber 22, the limiting plate 5 blocks the buffer trolley 1 to prevent the buffer trolley 1 from colliding with the lifting and conveying mechanism 3.

[0051] Referring to FIG3, in one embodiment of the present invention, the buffer trolley 1 is provided with a buffer cavity 14 for storing trays. The buffer cavity 14 is provided with multiple trays 15 spaced apart vertically on both sides along the horizontal direction. The trays 15 on both sides are used to support the two ends of the trays, and the trays 15 are used to buffer multiple layers of trays along the vertical direction.

[0052] Referring to FIG3, in one embodiment of the present invention, the pallet 15 is provided with a positioning pin 151, which is used to insert into the positioning hole 121 of the pallet to prevent the pallet from falling during the transfer process.

[0053] Referring to FIG4, in one embodiment of the present invention, the lifting and conveying mechanism 3 includes a lifting linear module 31 and a transverse linear module 32. The lifting linear module 31 is disposed at the output end of the transverse linear module 32. The transverse linear module 32 is used to move the lifting linear module 31 along the moving direction. The output end of the lifting linear module 31 is connected to a bracket 33 for supporting the pallet.

[0054] Referring to FIG1, in one embodiment of the present invention, a transverse linear module 32 is disposed on the frame 2 and is disposed facing the storage chamber 22 so as to input and output the tray of the buffer trolley 1 in the storage chamber 22.

[0055] Referring to FIG7, in one embodiment of the present invention, a plurality of reinforcing plates 21c are connected to the side of the side plate 21 away from the storage chamber 22. The reinforcing plates 21c are used to strengthen the structural strength of the side plate 21 and provide stable support for the guide wheel 13.

[0056] Referring to FIG3, in one embodiment of the present invention, metal plates 12 are connected to both sides of the buffer trolley 1. The metal plates 12 are provided with positioning holes 121. After the pin 41 is inserted into the positioning hole 121, the buffer block 44 abuts against the metal plate 12. Compared with plastic parts, the metal plate 12 is more resistant to repeated friction of the pin 41, thus extending its service life.

[0057] Referring to FIG5, in one embodiment of the present invention, the buffer block 44 is configured as a hollow cylinder, which reduces weight while ensuring buffering performance and avoids increasing the load on the frame 2. The axis of the hollow cylinder is perpendicular to the moving direction.

[0058] Referring to FIG5, in one embodiment of the present invention, the side plate 21 is provided with a clearance hole 45 for the fixed seat 43 to pass through. When the buffer trolley 1 is in place, the driver pushes the fixed seat 43 and the pin 41 through the clearance hole 45 into the storage chamber 22 to lock the buffer trolley 1. The purpose of setting the clearance hole 45 is to prevent the locking mechanism 4 from interfering with the buffer trolley 1.

[0059] The working principle of the automatic tray retrieval and buffer device described in this utility model is as follows:

[0060] When the pallet is being loaded, the operator pushes the buffer trolley 1 into the storage chamber 22. With the cooperation of the guide wheels 13 and the guide ramp 21b, the buffer trolley 1 moves precisely to the lifting and conveying mechanism 3 until it stops against the limit plate 5. Then, the locking mechanism 4 locks the buffer trolley 1. The robotic arm places the full pallet on the bracket 33. The lifting linear module 31 adjusts the pallet vertically to align it with the empty space in the buffer cavity 14. The horizontal linear module 32 moves the pallet horizontally into the buffer cavity 14. The lifting linear module 31 lowers the pallet so that it lands on the shelf. On the pallet 15, this process is repeated until the buffer trolley 1 is full. Finally, after the locking mechanism 4 unlocks the buffer trolley 1, the operator pulls out the buffer trolley 1 and pushes the next buffer trolley 1 into the storage chamber 22 for pallet buffering. When outputting the pallet, the operator pushes the buffer trolley 1 with the pallet into the storage chamber 22, the locking mechanism 4 locks the buffer trolley 1, the horizontal linear module 32 extends the bracket 33 into the bottom of the pallet, the lifting linear module 31 lifts the pallet, and the horizontal linear module 32 then moves the pallet out of the buffer trolley 1, and so on.

[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
