Description

Technical Field

[0001] This utility model relates to the field of depalletizing technology, specifically to a depalletizing device that automatically identifies information on items entering and leaving the warehouse. Background Technology

[0002] In today's rapidly developing industrial and technological society, intelligent development is a crucial direction. When goods enter and leave a warehouse, it's necessary not only to record the information and quantity of goods but also to depalletize and unpalletize them. To achieve these functions, two types of equipment are required: a barcode scanner and a depalletizing / unpalletizing device. The barcode scanner can utilize an RFID radio frequency scanning device disclosed in the applicant's earlier Chinese utility model patent (CN214421472U), which includes a conveying device located below a gantry-type housing. An RFID radio frequency identification module is installed inside the housing, and shielded doors are installed at both the inlet and outlet of the gantry-type housing. However, this barcode scanner also requires a depalletizing / unpalletizing device during the warehousing process, resulting in a large footprint and high cost, making it unsuitable for small spaces. Therefore, a miniaturized warehousing device that integrates barcode scanning and depalletizing / unpalletizing is needed. Utility Model Content

The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0024] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The use of "belonging" in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this invention.

The conveying device 9 adopts an existing roller conveyor, and the specific structure of the conveying device will not be described in detail in this embodiment.

[0026] In this embodiment, a left mounting plate and a right mounting plate 13 are movably mounted vertically inside the gantry-type housing 1. Two or more RFID scanning modules 14 are mounted on the left and right mounting plates along the front-to-back direction. In this embodiment, each mounting plate has four RFID scanning modules 14. Each RFID scanning module includes a reader for reading the item information stored in the RFID electronic tags on items on the AGV and conveyor. Each mounting plate is mounted on the gantry-type housing via guide blocks and guide rails (i.e., guide rails are provided on the gantry-type housing, and guide blocks are provided on each mounting plate). Conveyor belts are provided on each side wall of the gantry-type housing, which move the corresponding mounting plates up and down to adjust the position of the RFID scanning modules to meet the needs of scanning and identifying item information. The gantry-type housing has a first entrance / exit for AGV trolleys and a second entrance / exit for items on the conveyor system. Both the first and second entrances / exits are equipped with electric doors 7, which can be opened and closed. When the RFID scanning module is required to operate, the electric doors can be closed to avoid interference from external information and ensure the accuracy of statistics. A display screen 8 is installed on the gantry-type housing.

[0027] The depalletizing / unpalletizing mechanism 6 includes a top plate 19 symmetrically arranged on the left and right sides and a top plate driving mechanism. The top plate is used to cooperate with the items to be loaded or unloaded to realize the transfer of items. In this embodiment, the side wall of the box frame 5 used to place the items is provided with a groove for the top plate to be inserted. The top plate driving mechanism can drive the top plate to move in the up-down, left-right, and front-back directions to realize the depalletizing / unpalletizing process between the AGV trolley and the conveying device. The specific structure of the depalletizing / unpalletizing mechanism is as follows:

[0028] The stacking and unstacking mechanism includes a left movable frame and a right movable frame arranged symmetrically. The left and right movable frames have the same structure, and one of them will be described below. The movable frame includes a first mounting frame 15 that is movably mounted vertically on the inner wall of the gantry-type housing. A second mounting frame 17 is movably mounted on the first mounting frame 15 in the front-to-back direction. A third mounting frame 24 is movably mounted on the second mounting frame in the left-to-right direction. Each top plate 19 is correspondingly mounted on the corresponding third mounting frame 24. The top plate driving mechanism includes a vertical driving mechanism for driving the first mounting frame to move vertically, a front-to-back driving mechanism for driving the second mounting frames to move forward and backward, and a left-to-right driving mechanism for driving the third mounting frames and their top plates to move left and right.

[0029] A first guide rail 22 extending vertically is provided on the gantry-type housing 1, and a first mounting frame is vertically guided and mounted on the first guide rail. The vertical drive mechanism includes an upper sprocket, a lower sprocket, and a conveyor chain 30. The first mounting frame 15 is connected to the conveyor chain via a connecting column 16. The vertical drive mechanism also includes a first drive motor that drives the upper sprocket to rotate. Both the first drive motor and the conveyor belt drive motor are located inside the upper top wall of the gantry-type housing. A second guide rail 23 extending longitudinally is provided on the first mounting frame 15, and the second mounting frame is vertically guided and mounted on the second guide rail. The longitudinal drive mechanism includes a first rack 18 extending longitudinally on the second mounting frame, a second drive motor on the first mounting frame, and a first gear meshing with the first rack on the motor shaft of the second drive motor. The longitudinal movement of the second mounting frame is achieved through a gear-rack structure.

[0030] The second mounting frame 17 is provided with a third guide rail 25 extending in the left-right direction, and the third mounting frame 24 is guided and moved left and right on the third guide rail 25. The left-right drive mechanism includes a second rack 27 extending in the left-right direction on the third mounting frame, a third drive motor 26 on the second mounting frame, and a second gear 28 meshing with the second rack 27 on the motor shaft of the third drive motor. The left-right movement of the third mounting frame and its top plate is also achieved through the gear-rack structure. In this embodiment, the second mounting frame 17 has a mounting box 29, and the third mounting frame and the left-right drive mechanism are all located inside the mounting box. The box wall is provided with a through hole for the top plate to extend out. The second mounting frame is provided with a front correction structure and a rear correction structure to correct the items to be destacking on the AGV trolley. In this embodiment, each correction structure includes a first correction block 20 and a second correction block 21 that cooperate with the two sides of the corresponding end corners of the box frame for correcting the box frame.

[0031] When destacking is required on a palletized box frame on an AGV, the AGV transports the palletized box frame to the positioning structure of the gantry-type housing. A mobile RFID scanning module scans the items inside the box, identifying the stored information on the RFID tags on the items. Then, a super-palletizing mechanism transfers the box frame layer by layer from the AGV to the conveyor, thus achieving destacking. When palletizing is needed, a conveyor transports a box frame containing items. An RFID scanning module scans the items inside the box, and then a de-palletizing mechanism stacks the box frame transported by the conveyor onto the AGV, which then transports it away.
