[0029] Figure 1 This is a schematic diagram of the structure of the pallet depalletizer provided in the embodiment of the present application. Figure 1 The pallet depalletizing machine shown may include: a frame 10, a lifting mechanism 20, a driving mechanism 30, a conveying mechanism 40 and a depalletizing mechanism 50.

[0030] The frame 10 may be roughly rectangular, forming a gantry-like structure, thereby forming a pallet splitting station therein. Materials carried by multiple stacked pallets 60 may enter the pallet splitting station for pallet separation operations.

[0031] The lifting mechanism 20 is a movable device that can move back and forth in the height direction relative to the frame. It can be physically connected to the pallet 60 by the depalletizing mechanism 50, so that one of the pallets can follow the movement of the lifting mechanism 20 and be separated from other pallets.

[0032] Specifically, Figure 2 As shown, the pallet 60 may be provided with notches 61 of a specific number and spacing on both sides to facilitate the insertion of supports or other similar flat structures into the pallet to support the pallet to complete operations such as disassembly and transportation of the pallet. Figure 2 The case where two notches 61 are provided is exemplarily shown in FIG.

[0033] The depalletizing mechanism 50 is a structural member with a protruding portion, which is detachably connected to the lifting mechanism 20 and can reciprocate in the horizontal direction relative to the lifting mechanism 20, thereby inserting into or leaving the notch of the tray 60, thereby establishing or releasing the physical connection with the tray 60 that can transmit the force.

[0034] The driving mechanism 30 is a device fixed on the frame to provide a force for the lifting mechanism 20. It can be physically connected with the lifting mechanism to transmit power, so that the force is transmitted to the lifting mechanism to drive the lifting mechanism to move to a desired height.

[0035] Specifically, Figure 3 As shown, the driving mechanism 30 includes: a driving motor 31 and a transmission assembly 32. The driving motor 31 is fixed on the top of the frame and can convert electrical energy into mechanical energy of rotational motion. The transmission assembly 32 connects the driving motor and the lifting mechanism to play the role of power transmission and changing the motion mode.

[0036] Therefore, under the action of the transmission assembly, the rotational motion output by the drive motor can be converted into movement of the lifting mechanism along the height direction, thereby completing the pallet splitting.

[0037] The conveying mechanism 40 is a device for conveying materials to be separated. At least a part of the conveying mechanism 40 is located in the frame, and the materials to be separated can be moved to the pallet separation station, and after the pallet separation is completed, the separated pallet is moved out of the pallet separation station.

[0038] Specifically, Figure 4 As shown, the conveying mechanism 40 can be a continuous conveying roller. A part of it in the frame forms the above-mentioned pallet disassembly station, and a sensor can be provided to detect whether a plurality of stacked pallets are moved into place.

[0039] In the present invention, a depalletizing mechanism 50 and a lifting mechanism 10 together form a component that can be referred to as a depalletizing arm. The depalletizing arms can be arranged in pairs and symmetrically located on both sides of the pallet depalletizing station, thereby ensuring that the pallet can be stably and reliably lifted to achieve the operation of pallet separation.

[0040] Specifically, the two pairs of lifting mechanisms 20 can be symmetrically arranged on both sides of the pallet splitting station along the conveying direction of the conveying mechanism, so that the pallet can be lifted under the action of balanced supporting forces on both sides.

[0041] In actual use, N stacked pallets are transported to the pallet splitting station by the conveying mechanism 40. Then, after the depalletizing arm moves to the desired height, N-1 pallets other than the bottom pallet are lifted. Finally, the conveying mechanism 40 delivers the bottom pallet from the pallet splitting station, completing the splitting of one pallet. After the above steps are performed on the remaining N-1 pallets in sequence, the splitting of the N stacked pallets can be achieved.

[0042] In some embodiments, Figure 5 As shown, the lifting mechanism 20 includes: a lifting mechanism body 21, a telescopic cylinder 22 and a horizontal guiding mechanism 23.

[0043] The lifting mechanism body 21 is roughly rectangular and can provide sufficient component installation positions and supporting forces.

[0044] The telescopic cylinder 22 is fixedly arranged on the lifting mechanism body 21. The cylinder body of the telescopic cylinder 22 is rigidly connected to the lifting mechanism body 21, and the piston end thereof is rigidly connected to the destacking mechanism 50 to drive the destacking mechanism 50 to move in the horizontal direction.

[0045] Preferably, in addition to the depalletizing mechanism 50 being replaceable, the telescopic cylinder 22 can also be configured as a replaceable structure, so as to meet the limitations of different depalletizing mechanisms 50 and the movement range of the pallet in the horizontal direction.

[0046] The horizontal guide mechanism 23 is a mechanism that plays a guiding role. At least a part of it is fixedly arranged on the lifting mechanism body, and another part that cooperates with each other is arranged on the destacking mechanism. Through the cooperation of the two parts, the destacking mechanism 50 is guided to move in the horizontal direction.

[0047] In actual use, the telescopic cylinder drives the destacking mechanism to move to an ideal position in the horizontal direction through the extension and retraction of the piston end under the guidance of the horizontal guide mechanism. Specifically, the horizontal guide mechanism may include: a guide column arranged in the horizontal direction.

[0048] Preferably, in order to avoid the problem that the destacking mechanism may be bent due to excessive weight of the pallet, thereby causing malfunction, the lifting mechanism may also include an additional destacking mechanism bracket 24.

[0049] The destacking mechanism bracket 24 is fixed to the lifting mechanism body and is located at a position corresponding to the destacking mechanism. It can support the destacking mechanism in the direction of gravity, thereby supporting and increasing the load-bearing capacity of the destacking mechanism.

[0050] In some embodiments, Figure 6 and Figure 7 As shown, the destacking mechanism 50 includes a destacking mechanism body 51 and a protruding portion 52 .

[0051] The destacking mechanism body 51 is rigidly connected to the lifting mechanism in a detachable manner, so as to follow the movement of the lifting mechanism in the height direction. Specifically, the destacking mechanism body 51 is detachably connected to the lifting mechanism through a threaded fastener (eg, a screw).

[0052] The protrusion 52 is a protruding portion extending from the depalletizing mechanism body 51 in the horizontal direction. The protrusion may be provided with one or more protrusions according to actual needs. Specifically, the multiple protrusions 52 will be matched with the notches of the tray 60, so that when the depalletizing mechanism moves to the first extreme position in the horizontal direction, at least a part of the protrusions 52 is inserted into the tray; and when the depalletizing mechanism moves to the second extreme position in the horizontal direction, the protrusions 52 are separated from the tray in space.

[0053] In this embodiment, the first limit position and the second limit position refer to the two limit end points of the range in which the depalletizing mechanism 50 can move in the horizontal direction. Figure 6 As shown in FIG. 1 , when in the first extreme position, the protrusion of the depalletizing mechanism 50 passes through the notch of the pallet and is inserted into the area where the pallet is located. Figure 7 As shown, when in the second extreme position, the protruding portion of the depalletizing mechanism 50 is relatively far away from the pallet, and is spatially separated from the pallet.

[0054] Specifically, to adapt to a variety of different pallet models (for example, pallets with different pallet sizes, notch positions and notch numbers), multiple depalletizing mechanisms may be provided, so that the number and position of the protrusions in each depalletizing mechanism are compatible with at least one type of notch of the pallet. Figure 8 As shown, the depalletizing mechanism may be provided with two protrusions, which are used in conjunction with a pallet provided with two pallet notches, and the protrusions may be inserted into the pallet through the pallet notches.

[0055] Therefore, the user can easily and simply realize the disassembly of stacked pallets of different pallet models by replacing different destacking mechanisms.

[0056] Preferably, the rack may also be provided with a plurality of sensors, which may be selected to use any suitable type of sensor, such as an infrared sensor or a position sensor, according to actual needs.

[0057] It can detect and determine the current location of the pallet and whether multiple stacked pallets have entered the pallet splitting station, so as to orderly control the mutual coordination between one or more functional structures in the pallet depalletizer to realize the automated splitting of the pallet.

[0058] The above contents are further detailed descriptions of the present invention in combination with specific / preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
