This device can be removed when the equipment is located between production lines. When this sensor receives a signal, the equipment will no longer stack (buffer) pallets. A front end positioning sensor 16 is installed at the bottom front end to detect the front end positioning of the pallet. A rear end positioning sensor 25 is installed at the bottom rear end to detect the rear end positioning of the pallet. When this equipment is at the front end of the production line, it can be used as a pallet unpacking machine. A forklift can place a stack of pallets on the production line below this equipment. This equipment can unpack pallets and center them. When this equipment is positioned anywhere on the production line, it can stack and unstack pallets, acting as a pallet buffer. In this case, roller 7 needs to be removed. When this equipment is at the end of the production line, it can stack pallets, arranging them neatly from the previous station. When the stack reaches a certain height, the three-color light 2 emits an audible and visual alarm, reminding personnel to move the entire stack of pallets elsewhere. By adding a centering device, the incoming and outgoing pallets are kept aligned. Using cylinders instead of motors, chains, and other lifting devices simplifies the design, makes maintenance and upkeep easier, and allows for multiple functions in one machine.

[0023] like Figure 1 As shown, an upper crossbeam 9 is provided on the upper side of the frame 1. The upper crossbeam 9 is installed and connected to the frame 1 by screws. A button box 4 is provided on the side of the left and right guards 3. The button box 4 is equipped with control buttons and is used for manual loading and unloading.

[0024] like Figure 2As shown, a network port 22 is provided on the right side of the frame 1 near the rear end. A DC power interface 24 is provided at the bottom of the network port 22. An air source interface 23 is provided at the bottom of the DC power interface 24. The network port 22, the DC power interface 24 and the air source interface 23 are used to plug into the corresponding connection structure for signal transmission.

[0025] like Figure 1 As shown, a rear stop 5 is provided at the rear side of the frame 1. The rear stop 5 is driven to move up and down by a cylinder. A front stop 6 is provided on the front side of the rear stop 5 and on the frame 1. A roller 7 is provided on the side of the front stop 6. The two sides of the roller 7 are connected to the frame 1 by screws. The rear stop 5 and the front stop 6 are used to assist in blocking.

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, a bottom mounting plate 27 is provided at the bottom of the frame 1. The bottom mounting plate 27 is installed and connected to the frame 1 by welding. The bottom mounting plate 27 has a through hole. A pre-installed connecting base plate 25 is provided at the bottom of the frame 1. A movable locking limit block 28 is provided on the side of the bottom mounting plate 27. A bottom movable connecting block 30 is provided at the bottom of the movable locking limit block 28. A limit moving groove 29 is provided on the outer side of the bottom movable connecting block 30. A rotating connecting cylinder 33 is provided at the bottom of the bottom movable connecting block 30. An internal thread is provided on the inner side of the rotating connecting cylinder 33. A central connecting threaded post 32 is provided at the middle of the rotating connecting cylinder 33. A side connecting post 34 is provided on the side of the rotating connecting cylinder 33, and a toggle adjustment knob 31 is provided in the middle of the central connecting threaded post 32. In use, the pre-installed connecting base plate is first pre-installed in the designated position with screws, and then the central connecting threaded post is rotated by rotating the toggle adjustment knob. The rotation of the central connecting threaded post can cause the moving locking limit block to move through the thread action, thereby squeezing and locking the bottom mounting connecting plate. The internal threads of adjacent rotating connecting cylinders are opposite in direction. After the improvement of this utility model, users can more conveniently and quickly install, disassemble and replace the multi-functional pallet buffer device, thereby effectively improving the work efficiency of staff and the practicality of the multi-functional pallet buffer device.

[0027] During operation, after the pallet is placed on the assembly line, it moves backward towards the rear of the equipment until the rear-end positioning sensor 25 detects the pallet and stops. At this time, the centering guide rod 10 of the centering device moves inward towards the equipment under the action of the centering cylinder 12, causing the irregularly shaped pallets to converge towards the center. Then, the lifting cylinder 20 is activated and rises to its position. The fork 21, driven by the rotary cylinder 17, extends inward towards the equipment. At this time, the fork 21 is positioned in the gap between the second layer of pallets. Then, the second-stage cylinder 19 is activated and rises, and the fork 21 lifts the second layer of pallets, causing them to detach from the first layer of pallets. Then, the rear stop 5 rises, and the pallets on the assembly line move backward. Figure 5 The flow is from left to right. At this time, the first-stage cylinder 20 and the second-stage cylinder 19 descend simultaneously, and the pallet on the fork 21 falls onto the lower conveyor line. At this time, the upper surface of the fork 21 detaches from the upper surface of the pallet gap, and the fork 21 retracts. The first-stage cylinder 20 rises again, and so on, separating the pallets layer by layer onto the conveyor line until the front-end positioning sensor 16 and the rear-end positioning sensor 25 can no longer detect the pallet. At this time, the three-color light 2 issues an alarm. When the pallet flow direction is left in and right out, this equipment can be used as a stacking buffer machine. The pallet from the previous station flows in, and the rear block 5 is in the raised state. When the pallet stops after hitting the front block 6 of the equipment, the front-end positioning sensor 16 senses the pallet, the fork 21 extends, and the first-stage cylinder 20 and the second-stage cylinder 19 rise to the top at the same time. The centering cylinder 12 drives the centering guide rod 10 to move inward to the inside of the equipment, pushing the pallet to the center of the equipment and then retracting it. When the pallet flows in again and is detected by the front-end positioning sensor 16, the second-stage cylinder 19 descends. At this time, the pallet on the fork tines 21 falls on top of the first pallet. The fork tines 21 are now in the gaps of the second layer. After the fork tines 21 retract, the first-stage cylinder 20 descends to the origin. The fork tines 21 extend again, and the first-stage cylinder 20 and the second-stage cylinder 19 rise to the top at the same time. This process repeats until the height monitoring sensor 26 detects the pallet. Then, the tri-color light 2 activates an audible and visual alarm to remind personnel to move the stacked pallets to another location for storage.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
