[0024] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0025] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0027] The embodiment of the utility model provides a conveying device for a pallet, such as Figure 1 and Figure 2 As shown, it includes a conveying assembly 100, a chassis 200, a driving assembly 300 and a plurality of clamping assemblies 400. The conveying assembly 100 is connected to the chassis 200 and is used to drive the chassis 200 to move along the conveying direction of the pallet 11. The driving assembly 300 and the clamping assembly 400 are both arranged on the chassis 200. When the conveying assembly 100 drives the chassis 200 to move along the conveying direction, the driving assembly 300 and the clamping assembly 400 also move along the conveying direction following the chassis 200. The driving assembly 300 can drive the clamping assembly 400 to clamp the crossbar at the bottom of the pallet 11, and the driving assembly 300 can also drive the clamping assembly 400 to separate from the crossbar.

[0028] When the pallet conveying device of this embodiment is used, the entire pallet conveying device is set below the pallet 11, and the goods 12 are placed on the pallet 11. The driving assembly 300 drives the clamping assembly 400 to clamp the crossbar at the bottom of the pallet 11, and in the conveying direction, the movement of the pallet 11 relative to the entire conveying device is restricted, and the pallet 11 can maintain a higher consistency of synchronous movement with the base frame 200 to ensure that the pallet 11 is accurately conveyed to the right place. When the pallet 11 is conveyed to the right place, the driving assembly 300 can drive the clamping assembly 400 to separate from the crossbar at the bottom of the pallet 11.

[0029] In some embodiments, the clamping assembly 400 includes two clamping plates 410 distributed along the conveying direction, a clamping groove 420 is formed between the two clamping plates 410, and the two clamping plates 410 are synchronously connected with the base frame 200, that is, when one clamping plate 410 moves relative to the base frame 200, the other clamping plate 410 also moves synchronously relative to the base frame 200. The driving assembly 300 is used to drive the two clamping plates 410 to move synchronously relative to the base frame 200. Specifically, the driving assembly 300 can drive the two clamping plates 410 to rotate synchronously relative to the base frame 200, move synchronously along a preset direction, or move in other ways. The two clamping plates 410 can change the relative position of the clamping plates 410 and the tray 11 through synchronous movement relative to the base frame 200. When the crossbar at the bottom of the tray 11 is inserted into the clamping groove 420, the two clamping plates 410 clamp the crossbar at the bottom of the tray 11. In the conveying direction, the front and rear sides of the crossbar in the clamping groove 420 are blocked by the two clamping plates 410, respectively, thereby limiting the movement of the tray 11 relative to the base frame 200 in the conveying direction. When the crossbar at the bottom of the tray 11 moves out of the clamping groove 420, the two clamping plates 410 separate from the crossbar at the bottom of the tray 11, and the entire clamping assembly 400 no longer clamps the crossbar at the bottom of the tray 11.

[0030] Furthermore, the two clamping plates 410 are synchronously connected to the base frame 200 for rotation, and the rotation axes of the two clamping plates 410 and the base frame 200 are parallel to the conveying direction, and the driving assembly 300 is used to drive the two clamping plates 410 to rotate synchronously relative to the base frame 200. The crossbar at the bottom of the tray 11 is inserted into the clamping groove 420 between the two clamping plates 410 or the crossbar at the bottom of the tray 11 is moved out of the clamping groove 420 by rotating.

[0031] In this case, the extension direction of the crossbar at the bottom of the tray 11 is preferably perpendicular to the conveying direction, so that the crossbar can be smoothly inserted into or removed from the clamping groove 420. At the same time, it is ensured that the two clamping plates 410 can be located at the front and rear sides of the crossbar in the conveying direction.

[0032] Furthermore, the driving assembly 300 includes a driver 310, a rotating arm 320 and a connecting rod 330. The rotating arm 320 is connected to the driver 310. The driver 310 is used to drive the rotating arm 320 to rotate. One end of the connecting rod 330 is rotatably connected to the rotating arm 320, and the other end is rotatably connected to the clamping plate 410. The rotation axis of the rotating arm 320, the rotation axis of the connecting rod 330 and the rotating arm 320, and the rotation axis of the connecting rod 330 and the clamping plate 410 are all parallel to the conveying direction, ensuring that the rotating arm 320, the connecting rod 330 and the clamping plate 410 can rotate on the same or parallel planes. When the driver 310 drives the rotating arm 320 to rotate, the clamping plate 410 can be driven to rotate through the transmission of the rotating arm 320 and the connecting rod 330. Among them, the driver 310 can be a motor.

[0033] In other embodiments, the two clamping plates 410 are synchronously connected to the bottom frame 200 by sliding in the vertical direction, and the driving assembly 300 is used to drive the two clamping plates 410 to slide in the vertical direction relative to the bottom frame 200. When the driving assembly 300 drives the two clamping plates 410 to slide vertically upward relative to the bottom frame 200, the cross bar at the bottom of the tray 11 can be inserted into the clamping groove 420 between the two clamping plates 410; when the driving assembly 300 drives the two clamping plates 410 to slide vertically downward relative to the bottom frame 200, the cross bar at the bottom of the tray 11 can be removed from the clamping groove 420 between the two clamping plates 410.

[0034] It should be noted that, compared with the method in which the two splints 410 are synchronously connected to the base frame 200 by sliding in the vertical direction, the synchronous rotation connection between the two splints 410 and the base frame 200 can reduce the moving stroke of the splints 410 in the vertical direction, thereby saving space and facilitating the installation of the entire conveying device.

[0035] In other embodiments, the clamping assembly may include two jaws, and the driving assembly is used to drive the two jaws to move toward or away from each other. When the two jaws move toward each other, the two jaws can clamp the cross bar at the bottom of the tray. When the two jaws move away from each other, the two jaws are separated from the cross bar at the bottom of the tray 11.

[0036] Of course, the clamping assembly may also use other structures.

[0037] In some embodiments, the conveying assembly 100 includes a guide rail 110 extending along the conveying direction, and the base frame 200 is slidably matched with the guide rail 110. The guide rail 110 guides the movement of the base frame 200, guiding the base frame 200 to slide stably along the conveying direction. A slider 210 may be provided at the bottom of the base frame 200, and the slider 210 is slidably matched with the guide rail 110 to enable the base frame 200 to move along the conveying direction.

[0038] Furthermore, the conveying assembly 100 also includes a driving mechanism and a chain connected to the driving mechanism, the chain is fixedly connected to the base frame 200, and the driving mechanism is used to drive the chain to move along the conveying direction, thereby driving the base frame 200 to move along the conveying direction.

[0039] In some embodiments, the conveying device of the tray further includes a guide support assembly, on which the tray 11 to be conveyed is placed, and the tray 11 can slide along the conveying direction on the guide support assembly. The guide support assembly can support the tray 11 to reduce the force on the base frame 200, and guide the tray 11 to enable it to move stably along the conveying direction.

[0040] Furthermore, the guide support assembly includes two guide wheel groups, each of which includes a plurality of guide wheels 510 distributed along the conveying direction. The tray 11 to be conveyed is used to be placed on the guide wheels 510 of the two guide wheel groups, and the guide wheels 510 can rotate to reduce the friction force when the tray 11 moves, so that it can move smoothly along the conveying direction. The base frame 200 is arranged between the two guide wheel groups, and the space between the two guide wheel groups is used for the clamping assembly to move, so that the clamping assembly can clamp to the cross bar at the bottom of the tray 11.

[0041] An embodiment of the utility model further provides a stacker, comprising a pallet conveying device according to any one of the above embodiments. For the specific description of the pallet conveying device, reference may be made to the above embodiments and will not be repeated herein.

[0042] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
