Description

Technical Field

[0001] This invention relates to the field of smart logistics or industrial automation technology, specifically to a pallet stacking and unstacking device. Background Technology

[0002] Pallets are the medium that transforms static goods into dynamic goods; they are a cargo-carrying platform, and moreover, a movable platform, or a mobile ground. Even goods that lose their flexibility when placed on the ground immediately gain mobility and become flexible, flowing goods once loaded onto a pallet, because goods on a pallet are always in a ready-to-move state. This dynamic loading and unloading method, based on pallets as the fundamental tool, is called palletizing.

[0003] In pallet use, pallets need to be stacked to save space. However, when needed, the stacked pallets need to be removed one by one. Traditional manual operation can no longer meet the needs of rapidly developing smart logistics and automated production. Moreover, manual operation cannot guarantee the stability of pallet stacking and has low operating efficiency. Existing automated pallet stacking and unstacking devices have drawbacks such as high cost, high maintenance cost, and difficulty in adapting to high temperature and dusty environments.

Detailed Implementation

[0022] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] The following embodiments can be understood as explaining a partial structure of the present invention individually, or as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0024] Example 1

[0025] A pallet stacking device, such as Figure 1-5 As shown, the system includes a frame 1, a lifting mechanism located at the lower part of both sides of the frame 1, and a support mechanism connected to the lifting mechanism and located at the bottom of both sides of the frame 1. The frame 1 includes two rectangular frames 101 facing each other vertically, a vertical bar 102 connecting the vertical corners of the two rectangular frames 101, and a horizontal bar 103 connecting adjacent vertical bars 102 on the side and back of the frame 1. The front end of the frame 1 is open and used to insert or remove a tray 14. The lifting mechanism is fixedly connected to the horizontal bars 103 on both sides of the frame 1. The telescopic end of the support mechanism is a tray 8. The travel of the tray 8 is such that it extends into the frame 1 to support the bottom of the tray 14, and retracts to the outside of the frame 1, disengaging from the bottom of the tray 14.

[0026] In this embodiment, the lifting mechanism is fixedly connected to the side wall of the frame 1 and is used to lift the support mechanism. The support mechanism is used to insert the telescopic end (pallet 8) into the bottom of the tray 14, and the tray 14 is stored and retrieved through the lifting action of the lifting mechanism.

[0027] Example 2

[0028] like Figure 1-5 As shown, the lifting mechanism includes a lifting cylinder 6, a fixed base 3, and a first guide device. The lifting cylinder 6 is fixedly connected to the fixed base 3. The piston rod of the lifting cylinder 6 extends vertically downward and is fixedly connected to a horizontally arranged first connecting plate 7. The fixed base 3 is fixedly connected to a crossbar 103 on the side of the frame 1. The first connecting plate 7 is connected to the fixed base 3 through the first guide device.

[0029] like Figure 1-5 As shown, the fixed base 3 includes a fixed plate 301 arranged vertically. The fixed plate 301 is fixedly connected to the crossbar 103 by bolts. A horizontally arranged mounting plate 302 is fixedly connected to the outer surface of the fixed plate 301. The cylinder of the lifting cylinder 6 is fixedly connected to the fixed plate 301. The piston rod of the lifting cylinder 6 can slide through the mounting plate 302.

[0030] like Figure 1-5 As shown, triangular stiffening plates 303 are fixedly connected between the two ends of the upper surface of the mounting plate 302 and the two sides of the outer surface of the fixing plate 301. The first guiding device includes linear bearings 5 ​​that penetrate the mounting plate 302 vertically and are located on both sides of the mounting plate 302. A guide optical shaft 4 is slidably connected inside the linear bearing 5. The bottom end of the guide optical shaft 4 is fixedly connected to the first connecting plate 7.

[0031] In this embodiment, when the lifting cylinder is activated, the piston rod of the lifting cylinder drives the first connecting plate to move up and down. The first connecting plate moves along a set trajectory under the guidance of the first guiding device, and then the first connecting plate drives the load-bearing mechanism to move up and down.

[0032] Example 3

[0033] like Figure 1-5 As shown, the supporting mechanism includes a transverse cylinder 11, a base plate 9, a support plate 8, and a second guide device. The upper two sides of the base plate 9 are fixedly connected to the bottom of the first connecting plate 7 via a second connecting plate 15. The cylinder of the transverse cylinder 11 is fixedly connected to the upper end of the base plate 9 via a fixed bracket 13. The piston rod of the transverse cylinder 11 extends laterally toward one side of the frame 1. The end of the piston rod of the transverse cylinder 11 is fixedly connected to the back of the support plate 8. The support plate 8 is slidably engaged with the second connecting plate 15 via the second guide device.

[0034] like Figure 1-5As shown, the pallet 8 includes a horizontal plate 801 for inserting into the bottom of the tray 14 and a vertical plate 802 fixedly connected to the upper rear side of the horizontal plate 801. The piston rod end of the horizontal cylinder 11 is fixedly connected to the back of the vertical plate 802. The lower surface of the pallet 8 is slidably engaged with the upper surface of the base plate 9.

[0035] like Figure 1-5 As shown, the second guiding device includes a linear slide rail 12 fixedly connected to the outside of two second connecting plates 15 and arranged in a horizontal direction. The slider on the linear slide rail 12 is fixedly connected to the top of the vertical plate 802 through a fixed connector 10.

[0036] In this embodiment, when the transverse cylinder is activated, the horizontal plate 801 passes through the side of the frame and enters the frame, inserting into the bottom of the tray. Under the guidance of the second guide device, the tray slides relative to the base plate along a set trajectory. After completing the lifting action and returning to the set position, the transverse cylinder retracts, moving the tray to the outside of the frame.

[0037] The working principle of this new type:

[0038] (1) When retrieving a pallet, the transverse cylinder is in the retracted state. Under the action of the lifting mechanism, the supporting mechanism rises, so that the horizontal plate reaches the bottom position of the second layer of pallets (counting from the bottom). The transverse cylinder is activated, and the pallet is inserted into the bottom of the second layer of pallets inside the frame. The lifting mechanism continues to lift the supporting mechanism along with the pallet to the set height. When the bottom pallet is taken away, there is a delay for a certain period of time (the time can be set in the touch screen from 0-60s). After the delay, the lifting mechanism lowers the supporting mechanism and places the original second layer pallet at the bottom of the frame (becoming the bottom pallet). The transverse cylinder retracts, and the pallet returns to the outside of the frame. In this way, the continuous removal of pallets can be achieved by repeating the action.

[0039] (2) When storing a pallet, the horizontal cylinder is in the retracted state. The lifting mechanism moves the pallet to the bottom of the bottom pallet. The horizontal cylinder is activated, and the pallet is inserted into the bottom of the bottom pallet. The lifting mechanism lifts the support mechanism together with the bottom pallet and the pallets above it to the set height. When the new pallet is moved into place at the bottom of the rack, there is a certain delay (the time can be set in the touch screen from 0 to 60 seconds). After the delay, the lifting mechanism lowers the support mechanism so that the original bottom pallet is stacked on top of the newly placed pallet. Then the horizontal cylinder retracts.
