[0025] The frame body 100 has an electric cabinet 101 on one side and an AGV trolley 102 at one end, which is convenient for unified control of the operation of various electrical appliances through the electric cabinet 101. There are two AGV trolleys 102, which are convenient for placing empty pallets and receiving finished product pallets respectively;

[0026] The conveying mechanism 200 includes a roller conveyor 1 201 and a roller conveyor 202;

[0027] The lifting mechanism 300 includes a lifting frame 1 301 and a lifting frame 2 302 arranged inside the frame body 100. A feed lifting motor 303 and a discharge lifting motor 304 are respectively arranged on the top of the lifting frame 1 301 and the lifting frame 2 302. The feed lifting motor 303 and the discharge lifting motor 304 are respectively connected to two roller conveyors 1 201 through a transmission shaft and a chain. A guide rail 305 is arranged at the bottom of the lifting frame 1 301 and the lifting frame 2 302. Feed clamping cylinders 306 are fixed on both sides of the lifting frame 1 301.

[0028] The palletizing mechanism 400 includes a mounting seat 401 and a delivery rack 402 arranged inside the frame body 100 , and a manipulator 403 is fixed on the top of the mounting seat 401 .

[0029] In addition, lifting frame 1 301 and lifting frame 2 302 are both U-shaped frame structures without a bottom plate and have the same opening direction. Lifting frame 1 301 and lifting frame 2 302 are respectively provided with a feed sensor 307 and a discharge sensor 308. Both the feed sensor 307 and the discharge sensor 308 use infrared sensors to facilitate monitoring of feed and discharge information, and convert the information into electrical signals to meet the requirements of information transmission, processing, storage, display, recording and control.

[0030] Specifically, there are two roller conveyors 201, which are respectively arranged in the lifting frame 1 301 and the lifting frame 2 302. A guide shoe 2011 is provided on one side of the roller conveyor 201. The roller conveyor 201 is slidably connected to the guide rail 305 through the guide shoe 2011, ensuring that when the lifting mechanism 300 drives the roller conveyor 201 to move in the vertical direction, the friction is smaller and the operation is more stable.

[0031] It is worth mentioning that there are two roller conveyors 202 in total. The two roller conveyors 202 are respectively arranged at one end of the two roller conveyors 1 201. One end of the roller conveyor 1 201 is provided with a feed conveying motor 203, which can provide power support for the roller conveyor 1 201. One end of the roller conveyor 202 is provided with a discharge conveying motor 204, which can provide power support for the roller conveyor 202, ensuring that the empty pallet on the roller conveyor 1 201 can be transported to the corresponding roller conveyor 2 202, and ensuring that the finished pallet on the other roller conveyor 202 can be transported to the corresponding roller conveyor 1 201.

[0032] Specifically, there are four feed clamping cylinders 306 in total. The four feed clamping cylinders 306 are fixed on both sides of the lifting frame 301 in groups of two, and the central axes of the two corresponding feed clamping cylinders 306 coincide with each other, which is convenient for clamping and fixing the empty pallets. The lifting mechanism 300 drives the roller conveyor 201 to move upward until the empty pallets on the second-to-last layer are aligned with the feed clamping cylinder 306. After the feed clamping cylinder 306 clamps the empty pallets on the second-to-last layer, the lifting mechanism 300 drives the roller conveyor 201 to move downward until it is aligned with the roller conveyor 202, and then the empty pallets on the bottom layer can be transported to the roller conveyor 202. By repeating the above operations, the stacked empty pallets can be transported in sequence. The ends of the feed clamping cylinders 306 are fixed with clamping plates 3061, which can increase the contact area and prevent the feed clamping cylinders 306 from damaging the pallets during the clamping and fixing process.

[0033] It should be noted that a suction cup 4031 is fixed to the end of the manipulator 403, and the bottom rotation range of the manipulator 403 is 0 to 90 degrees, ensuring that the manipulator 403 can transport an empty pallet on a roller conveyor 202 to another roller conveyor 202 through the suction cup 4031, and then place the finished product boxes on the shelf 402 on the empty pallet through the suction cup 4031 to achieve automatic palletizing.

[0034] Specifically, there are two AGV carts 102, which are respectively arranged at the openings of the lifting frame 1 301 and the lifting frame 2 302, so as to conveniently place empty pallets at the entrance of the automatic palletizer and automatically receive finished product pallets through the two AGV carts 102. The height of the AGV cart 102 is not lower than the lowest height of the roller conveyor 201, and is not higher than the highest height of the roller conveyor 201, so as to ensure that when the roller conveyor 201 is driven up and down by the lifting mechanism 300, the empty pallet can be separated from the AGV cart 102, and the finished product pallet can be placed on the AGV cart 102.

[0035] Working principle: When the material warehouse automatic palletizer is used, the AGV trolley 102 first transports the stacked empty pallets to the lifting frame 1 301, and then the feed lifting motor 303 drives the roller conveyor 1 201 to rise until the empty pallets are separated from the AGV trolley 102, and then the feed clamping cylinder 306 clamps and fixes the empty pallets on the second-to-last layer, and then the feed lifting motor 303 drives the roller conveyor 1 201 to descend until the roller conveyor 1 201 is flush with its corresponding roller conveyor 2 202, and then the feed conveying motor 203 is started to transport the empty pallets to the roller conveyor 2 20 2, and then the empty pallet is grabbed by the manipulator 403 and placed on another roller conveyor 202, and then the finished product boxes on the shelf 402 are stacked on the roller conveyor 202 by the manipulator 403, and the discharge conveying motor 204 is started to convey the product pallet to another roller conveyor 1 201, and then the discharge lifting motor 304 drives the roller conveyor 1 201 to rise. At this time, another AGV trolley 102 moves to the bottom of the finished product pallet, and then the discharge lifting motor 304 drives the roller conveyor 1 201 to descend until the finished product pallet is placed on another AGV trolley 102. The automatic palletizer for material warehouse is of advanced design, compact structure and easy to use. By setting a lifting mechanism 300 to drive the roller conveyor 201 to move in the vertical direction, the automatic palletizer can be directly docked with the AGV trolley 102. By setting a feed clamping cylinder 306 and a clamping plate 3061, the empty pallets on the second to last layer and above can be clamped and limited, so that the empty pallets can be input in sequence. The input empty pallets are grabbed and placed on another roller conveyor 202 by the manipulator 403 and stacked. This can meet the needs of placing empty pallets at the entrance of the automatic palletizer and the AGV trolley automatically receiving finished product pallets, greatly improving work efficiency.
