When a pallet loaded with materials reaches the transfer rack, the clamping device clamps the pallet, and the pallet is transferred above the receiving tray through the horizontal moving device. The dumping device dumps the materials on the pallet into the receiving tray and places the pallet on the pallet storage station.

[0006] Based on the above, the utility model is provided with a horizontal moving device, a lifting and clamping device, a loading position and an unloading position. The devices cooperate with each other to complete the processes of automatic handling, automatic pouring and automatic pallet stacking. Its structure is simple and the operation is stable, reducing the consumption of human resources and improving the work efficiency.

[0007] Further, the dumping device is provided with a driving source and a chain drive structure. The chain drive structure includes a driving shaft and a driven shaft. The driven shaft is arranged on both sides of the dumping device and is cooperatively connected with the clamping device. Sprockets are installed on the driving shaft and the driven shaft and are drivingly connected through the chain. The driving source drives the chain drive structure to control the clamping device to perform dumping and discharging.

[0008] Based on the above, the dumping device can dump the clamping device through the driving source, so that the materials on the pallet are dumped into the receiving tray, facilitating the collection of the materials.

[0009] Further, the driving source is arranged in the middle of the driving shaft. The driving source is provided with a pushing cylinder and a rack. The output end of the pushing cylinder is fixedly installed with the end of the rack. A gear is also installed in the middle of the driving shaft. The pushing cylinder pushes the rack to engage with the gear to drive the driving shaft to rotate.

[0010] Based on the above, the stroke of the pushing cylinder can control the dumping angle of the clamping assembly, and at the same time, the gear is used for motion transmission, improving the stability and rotation accuracy of the handling device.

[0011] Further, clamping cylinders and clamping plates are respectively arranged on both sides of the clamping device. The output end of the clamping cylinder is fixedly installed with the clamping plate. The clamping cylinder pushes the clamping plate to clamp the pallet. Both sides of the clamping device are also connected to the chain drive structure through the driven shaft.

[0012] Based on the above, the clamping device clamps the pallet through the clamping cylinder, making the pallet more stable during the transfer process, improving the working stability and working efficiency.

The lifting cylinder is fixedly installed on the slider plate, and the lifting guide rod is slidably engaged with the guide hole on the slider plate. The output end of the lifting cylinder is fixedly installed at the upper end of the lifting and clamping device, and the lifting of the lifting and clamping mechanism is adjusted by the lifting cylinder.

[0016] Based on the above, the lifting cylinder can control the lifting of the lifting and clamping device, and at the same time, the cylinder has strong pulling force and thrust, improving the stability and load-bearing capacity of the handling device.

[0017] Further, cylinder support frames are provided on both sides of the gear. The pushing cylinder is fixedly installed on the cylinder support frames. Convex ribs are provided inside the cylinder support frames, and the convex ribs are slidably engaged with the sliding grooves on the rack.

[0018] Based on the above, the sliding groove is slidably engaged with the rack, playing a guiding role and making the force on the rack more stable.

[0019] Further, a baffle and a position sensor are provided on the transfer rack, and the position sensor is installed on the baffle.

[0020] Based on the above, the transfer rack is provided with a baffle, which can be used to block the flow of the pallet, preventing the products from falling due to the handling mechanism not being able to transfer in time. The position sensor is installed on the baffle. When the pallet reaches the set distance, the horizontal moving device and the lifting and clamping device cooperate with each other to transfer the pallet above the storage hopper for dumping. The whole process is automated without manual intervention, improving the work efficiency and achieving the state of timely replenishment.

[0021] Further, the pallet storage station includes a pallet and a pallet sliding guide rail. A slider is slidably engaged with the pallet sliding guide rail, the pallet is fixedly installed on the slider, and a pressure spring is provided below the pallet to support the pallet.

[0022] Based on the above, after the clamping device dumps the products on the pallet into the receiving tray, the empty pallet is placed on the pallet. The spring below the pallet starts to compress a small distance under the influence of gravity, and so on. The empty pallets are stacked on the pallet, reducing the manual repetitive work.

[0023] Further, the transfer rack is composed of several rollers.

[0024] Based on the above, the several rollers facilitate the connection of the pallet flow into the transfer rack, improving the smoothness of the transfer.

This process is repeated, and the empty pallets are stacked on the pallet 36 and finally removed by the staff.

[0033] As Figure 2 shown, the lifting and clamping device 8 further includes a lifting device 27. The lifting device 27 includes a lifting cylinder 28 and a lifting guide rod 29. The lifting cylinder 28 is fixedly installed on the slider plate 26. The lifting guide rod 29 is slidably fitted with a guide hole 30 on the slider plate 26. The output end of the lifting cylinder 28 is fixedly installed at the upper end of the lifting and clamping device 8, and the lifting of the lifting and clamping mechanism is adjusted through the lifting cylinder 28.

[0034] As Figure 2 and Figure 3As shown, the tilting device 9 is provided with a drive source 12 and a chain drive structure 13. The chain drive structure 13 includes a driving shaft 14 and a driven shaft 15. The driven shaft 15 is arranged on both sides of the tilting device 9 and is cooperatively connected with the clamping device 10. Sprockets 16 are installed on the driving shaft 14 and the driven shaft 15 and are drivingly connected by a chain 17. The sprockets 16 are cooperatively installed at both ends of the driving shaft 14. The drive source 12 drives the chain drive structure 13 to control the tilting and discharging of the clamping device 10. The drive source 12 is arranged in the middle of the driving shaft 14. The drive source 12 is provided with a push cylinder 18 and a rack 19. The output end of the push cylinder 18 is fixedly installed with the end of the rack 19. A gear 20 is also installed in the middle of the driving shaft 14. Cylinder support frames 31 are arranged on both sides of the gear 20. The push cylinder 18 is fixedly installed on the cylinder support frames 31. Convex ridges 32 are arranged inside the cylinder support frames 31. The convex ridges 32 are in sliding cooperation with the sliding grooves 33 on the rack 19. The push cylinder 18 pushes the rack 19 to engage with the gear 20 for transmission to drive the driving shaft 14 to rotate.

[0035] As Figure 2 and Figure 5 shown, clamping cylinders 21 and clamping plates 22 are respectively arranged on both sides of the clamping device 10. The output end of the clamping cylinder 21 is fixedly installed with the clamping plate 22. The clamping cylinder 21 pushes the clamping plate 22 to clamp the pallet.

[0036] As Figure 4 shown, the horizontal moving device 7 is provided with a lead screw 23 and a slide bar 24. The slide bar 24 is fixedly installed on the frame 1. A driving block 25 is arranged on the lead screw 23. A slide block plate 26 is in sliding cooperation with the slide bar 24. The driving block 25 is fixedly connected with the slide block plate 26. The lead screw 23 is driven by a driving motor to drive the driving block 25 and the slide block plate 26 to move horizontally.

[0037] The specific implementation method is as follows: The utility model is a mechanism for connecting the glue injection production line part to realize automatic handling and pouring. When a tray of semi-finished products flows to the position of the transfer rack 4 of the mechanism, after the in-place sensor 35 detects that the pallet loaded with semi-finished products reaches the relevant position, the horizontal displacement mechanism and the lifting and clamping device 8 cooperate with each other to move the clamping device 10 to a suitable position. Then, the clamping device 10 clamps the pallet through the clamping cylinder 21 and rises. Subsequently, the motor drives the screw rod 23 to rotate, so that the driving block 25 on the screw rod 23 drives the pallet to move horizontally. After moving above the receiving tray 5, the pushing cylinder 18 pushes the rack 19 to drive the gear 20 to rotate the main shaft 14, thereby driving the sprockets 16 on both sides to make the chain 17 move, so that the clamping device 10 rotates more than 90 degrees, and the materials are completely poured into the receiving tray 5. Finally, it returns to the horizontal direction, stacks the empty pallets on the pallet storage station 6, and when the empty pallets are stacked to a certain height, they are taken away by the staff, thus completing the processes of automatic handling, automatic pouring, and automatic pallet stacking.

[0038] The above is only the optimal solution embodiment of the present utility model, and is not used to limit the present utility model. Various modifications or substitutions made by those skilled in the art to the present utility model without departing from the essence and protection scope of the present utility model should also be within the protection scope of the present utility model.
