The outlet is connected to the metering hopper 422, the transition bin 46 is connected to the upper bracket 44, the outlet of the transition bin 46 is connected to the lower storage hopper 43, the lower storage hopper 43 is connected to the lower bracket 45, the lower storage hopper 43 is connected to the homogenizing tank 5 through a pipeline and a vacuum suction device, and the homogenizing tank 5 is connected to the screw feeder 8 through a pipeline and a vacuum suction device.

[0026] A lighting bracket 6 is arranged on the side of the material stack 1 away from the automatic depalletizing system 2 , and a lighting lamp 61 is connected to the lighting bracket 6 to realize lighting near the material stack 1 , so as to ensure that the camera can accurately collect image information of the material stack 1 .

[0027] The mobile vehicle 21 is provided with pneumatic support feet 211 . When the mobile vehicle 21 and the pneumatic support feet 211 are started to support the ground, the stability of the mobile vehicle 21 can be ensured, thereby ensuring the stable operation of the four-axis manipulator 22 on the mobile vehicle 21 .

[0028] The four-axis manipulator 22 is also connected to the gas tank 221, and the gas tank 221 is connected to the pulse back-blowing valve 222. The pulse back-blowing valve 222 is connected to the spray hole set on the bag-taking suction cup 231. An empty bag recovery mechanism 7 is set between the automatic destacking system 2 and the bag-breaking system 3. The empty bag recovery mechanism 7 includes a recovery conveying line 71. The front end of the recovery conveying line 71 in the conveying direction is connected to a recovery box 72. A baffle 73 is also set on the recovery conveying line 71. After the bag-breaking puts the material into the bag-breaking hopper 31, the four-axis manipulator 22 can drive the bag-taking suction cup 231 and the sucked empty bag to move to the recovery conveying line 71, and turn off the negative pressure suction at the bag-taking suction cup 231. Then the pulse back-blowing valve 222 works, and the positive pressure air is quickly ejected through the spray hole, blowing the empty bag down and falling on the leather recovery conveying line 71. Then the recovery conveying line 71 moves forward, and the empty bag and the remaining material in the empty bag are sent to the recovery box 72 for collection.

[0029] The side wall of the upper storage hopper 41 is connected to a plexiglass valve 413, which can facilitate observation of the material in the hopper and convenient material cleaning. A conical funnel-shaped baffle is added under the lower storage hopper 41 to prevent material from remaining in the lower storage hopper 41 and affecting product quality. The front and rear sides of the upper bracket 44 are also equipped with plexiglass doors, and a proximity switch 441 is installed on the left side of the plexiglass door. The whole machine is interlocked to ensure human-machine safety.

[0030] When the intelligent material conveying system of this embodiment is used, the material bags are stacked on the corresponding material stack 1, and then the mobile vehicle 21 moves to the corresponding position. After the mobile vehicle 21 is in place, the pneumatic support foot 211 starts to support the bottom edge to position the mobile vehicle 21, and then the four-axis manipulator 22 starts to send the bag picking mechanism 23 to the material stack 1, and then the camera 232 and the rangefinder 233 obtain the shape and distance parameters of the material stack 1, and transmit them to the four-axis manipulator 22. The four-axis manipulator 22 changes its position accordingly so that the bag picking suction cup 231 can suck the material bag. After sucking the material bag; the pneumatic support foot 211 resets, and the mobile vehicle 21 moves to the corresponding position again. After it is in place, it is positioned again, and then the four-axis manipulator 22 drives the bag picking mechanism 23 and the material bag thereon to move to the corresponding bag breaking hopper 31; at the same time, the bag breaking hopper 31 The driving motor 33 drives the bag breaking saw blade 32 to rotate, the material bag drops and sticks to the motor mounting plate 311, and the four-axis manipulator 22 slides horizontally from left to right, and a notch is cut in the center of the material bag through the highly rotating bag breaking saw blade 32. The four-axis manipulator 22 stands still for about 10 seconds, and then quickly shakes up and down and left and right three times to shake off the remaining material in the material bag. The material enters the bag breaking hopper 31, and the bag breaking hopper 31 is equipped with an upper and lower material level meter. When the lower material level signal is detected, the four-axis manipulator 22 The material bag is immediately grabbed for bag breaking. When the upper material position signal is detected, the four-axis manipulator 22 stops the bag breaking action. After the material enters the bag breaking hopper 31, it is sent to the upper storage hopper 41 of the automatic batching and weighing system 4 through the vacuum suction machine, and then the pneumatic gate valve 412 of the upper storage hopper 41 allows the material to fall into the weighing hopper 42. When the weighing sensor 421 senses that the material in the weighing hopper 42 has reached the set value, the pneumatic gate valve 412 is controlled to close, and then the metering hopper door 422 is opened, so that the material in the weighing hopper 42 falls into the transition bin 46, and finally falls into the lower storage hopper 43. The material in the lower storage hopper 43 is then sucked into the homogenizing tank 5 by the vacuum suction machine, and various materials are fully mixed in the homogenizing tank 5. The evenly mixed material is then sent to the screw feeder 8 by the vacuum suction machine for continued transportation and supplied to customers.
