As an advanced material handling equipment, AGV intelligent forklifts integrate a variety of advanced technologies, such as automatic navigation, intelligent control, sensor technology, etc., which can realize automated and intelligent material handling.

[0003] In the related technology, for logistics pallets equipped with AGV intelligent forklifts, the exchange of empty and full pallets is a necessary process during the transportation process. The conventional operation is to set up two pallet positions. When the logistics consumption at one position is completed and becomes an empty pallet, the AGV intelligent forklift will take the empty pallet away and put a full pallet back at the other position, which will add a pallet position. Utility Model Content

[0004] In view of this, the utility model provides an empty and full pallet exchange device to solve the problem of needing to set two pallet positions in the related art.

[0005] The utility model provides an empty and full pallet exchange device, comprising:

[0006] A base having a through hole;

[0007] A placement area, located below the through hole;

[0008] a support structure movably disposed on the base, having a first position covering at least a portion of the through hole, and a second position away from the through hole, wherein when the support structure is in the first position, a tray carrying articles is suitable for being supported by the support structure, and when the support structure is in the second position, an empty tray is suitable for falling through the through hole to the placement area;

[0009] The driving mechanism is connected to the supporting structure and is used to drive the supporting structure to move.

[0010] Beneficial effect: When the empty and full pallet exchange device is used, when a pallet carrying items needs to be placed, the driving mechanism drives the support structure to move to the first position, and the AGV intelligent forklift places the pallet carrying items on the support structure. At this time, since at least part of the through holes are blocked by the support structure, the pallet cannot fall downward. When the items on the pallet are consumed and it becomes an empty pallet, the driving mechanism drives the support structure to move to the second position. At this time, the support structure no longer blocks the through holes, and the empty pallet falls downward into the placement area under the action of gravity. After that, the driving mechanism can continue to drive the support structure to move to the first position to place the pallet carrying items, and the AGV intelligent forklift can take away the empty pallet located in the placement area. Compared with the related art, the setting of the empty and full pallet exchange device can reduce one pallet position, occupy less space, improve space utilization, and shorten the action time of the forklift.

[0011] In an optional embodiment, the support structure includes two symmetrically arranged support plates, the support plates are movably arranged on the base along a straight line, and the driving mechanism includes two linear driving structures connected to the support plates in a one-to-one correspondence.

The AGV intelligent forklift places the pallet carrying items on the support plate. At this time, since at least part of the through holes are blocked by the two support plates, the pallet cannot fall down. When the items on the pallet are consumed and become an empty pallet, the two cylinders retract and drive the support plates to move away from each other and move to the second position. At this time, the support plates no longer block the through holes, and the empty pallet falls down to the placement area under the action of gravity. After that, the two cylinders can continue to drive the support plates to move to the first position to place the pallet carrying items. The AGV intelligent forklift can take away the empty pallet located in the placement area.

[0021] In an optional embodiment, the base includes two symmetrically arranged supporting feet, and the opposite sides of the two supporting feet are inclined and inclined from top to bottom in a direction approaching each other, and the area between the two supporting feet constitutes the placement area.

[0022] Beneficial effect: By tilting the opposite sides of the two supporting legs, the falling of the tray can be guided.

[0023] In an optional embodiment, the empty and full pallet exchanging device further includes a guide limiting structure, and the guide limiting structure is used to prevent the pallet from moving with the support plate when the support plate moves toward the second position.

[0024] Beneficial effect: By setting up the guide limit structure, the tray can be prevented from moving with the support plate when the support plate moves toward the second position, ensuring that the tray can fall downward to the placement area after the support plate moves to the second position.

[0025] In an optional implementation, the guide limiting structure includes:

[0026] A vertical portion, the lower end of which is fixedly connected to the base;

[0027] One end of the horizontal part is connected to the upper end of the vertical part, and the horizontal part is suspended.
