[0025] Please refer to Figures 1 to 4 , an automatic pallet return device, including

[0026] Boxes 10, there are two boxes 10, and on one side of the two boxes 10 close to each other, there are both a feeding port and a discharging port for feeding.

[0027] Transfer assembly 20, the transfer assembly 20 includes a holding unit and a transfer unit; it is installed inside the box 10, used to receive pallet A input from the feeding port when approaching the feeding port, and used to convey pallet A inside it from the discharging port to the outside when approaching the discharging port; the transfer unit is connected to the holding unit and is used to drive the holding unit to reciprocate between the feeding port and the discharging port.

[0028] Conveying assembly (not shown in the figure), the conveying assembly is connected to the feeding ports and discharging ports between the two boxes 10 and is used for the conveyance and return of pallet A.

[0029] In this embodiment, during operation, the tray A is driven by the conveying assembly and enters onto the placing unit through the feed inlet of the first box body 10. Then, the transfer unit drives the placing unit to move to the discharge outlet of the first box body 10. Thus, the placing unit conveys the tray A into the conveying assembly, and the conveying assembly then transfers the tray A to the feed inlet of the second box body 10. Thereby, the tray A is conveyed back to the conveying assembly from the discharge outlet of the second box body 10 through the transfer assembly 20 of the second box body 10, and then returns to the placing unit of the first box body 10 through the feed inlet of the first box body 10 again, so as to effectively form a reflux for the tray A. During operation, after an operator loads, assembles or performs other processes on the tray A located on the conveying assembly, the logistics on the tray A is taken back manually or automatically. Then, the empty tray A continues to move through the conveying assembly and the transfer assemblies 20 in the two box bodies 10, enabling the tray A in the production line to automatically reflux, replacing manual placement and recovery of the tray A, reducing labor costs, and greatly improving production efficiency.

[0030] A tray automatic reflux device according to the present utility model, through the settings of the box body 10, the transfer assembly 20 and the conveying assembly, can enable the tray A in the production line to automatically reflux, replace manual placement, and without manual intervention, recover the tray A, reduce labor costs, and greatly improve production efficiency.

[0031] In a specific embodiment, the feed inlet and the discharge outlet are vertically arranged; the feed inlet of the first box body 10 is horizontally aligned with the discharge outlet of the second box body 10, and the logistics transportation therebetween is realized through the conveying assembly; the discharge outlet of the first box body 10 is horizontally aligned with the feed inlet of the second box body 10, and the logistics transportation therebetween is realized through the conveying assembly. In this embodiment, for the convenience of docking of the conveying assembly, the feed inlet and the discharge outlet are in communication with each other. Further, by vertically arranging the feed inlet and the discharge outlet and realizing the transportation and reflux of the tray A through the conveying assembly, the horizontal space occupancy rate of the tray A reflux device is reduced, so that the structural layout of the workshop can be optimized, and the user experience is greatly improved.

[0032] In a specific embodiment, the holding unit includes two synchronous belts 201 arranged side by side and evenly, synchronous wheels installed at both ends of the synchronous belts 201, a transmission shaft 202 installed between the two synchronous belts 201 and connected to the synchronous wheels, and a first motor 203 connected to the transmission shaft 202 for driving the transmission shaft 202 to rotate. In this embodiment, the first motor 203 drives the synchronous wheels to rotate, and then drives the two synchronous wheels to rotate. During operation, the tray A enters onto the two synchronous belts 201 through the feeding port driven by the conveying component and is supported by the synchronous belts 201. When it needs to be conveyed from the discharging port, the first motor 203 drives the synchronous belts 201 to rotate through the transmission shaft 202 and the synchronous wheels, so that the tray A is output from the discharging port.

[0033] In a specific embodiment, the first motor 203 and the two synchronous belts 201 are on the same horizontal plane. Specifically, in this embodiment, by horizontally setting the first motor 203 instead of vertically installing it, the stroke range of the transfer unit is not occupied.

Among them, the holding unit is installed on the mounting plate 206. Specifically, in this embodiment, the discharging port and the feeding port are located between the lower bottom plate 204 and the upper top plate 205 in the vertical direction, so that when the holding unit moves with the mounting plate 206, it can be aligned with the feeding port and the discharging port respectively at the preset positions.

[0035] In a specific embodiment, the driving assembly includes a rotating chain 207 vertically installed between the lower bottom plate 204 and the upper top plate 205, sprockets 208 installed at both ends of the rotating chain 207, a second motor 209 connected to the sprockets 208 for driving the sprockets 208 to rotate so that the sprockets 208 drive the chain to rotate when rotating, and a connecting block 210 connected to the chain and the mounting plate 206 so that the mounting plate 206 moves relatively up and down when the chain rotates.
