Taking the clothes with soft package goods as an example, the picking system works as follows:
1. the upstream system receives the order information, and a transfer robot (AGV) transfers the target shelf 400 to a picking station according to the system information;
2. the mechanical arm 100 with the sucker assembly 200 moves to a code scanning position of the target container 300, and two-dimensional code information on the container 300 corresponding to the storage position is scanned to check whether the cargo position is correct;
3. after confirming that it is correct, the suction cup assemblies 200 extend into the cargo box 300 through the top opening 301 of the cargo box 300 and move down the side openings 302 of the cargo box 300 to search for clothes;
4. when the goods picking and detecting mechanism 8 detects clothes, a second signal is sent to the control mechanism of the mechanical arm 100, so that the mechanical arm 100 stops downward probing, meanwhile, the on-off electromagnetic valve 503 of the vacuum generating mechanism 500 is opened, the vacuum generator 501 starts to work, and the sucking disc 2 sucks the clothes;
5. after the completion of the picking up of the clothes, the robot arm 100 with the suction cup assembly 200 moves up to the safe position first and then exits the container 300, and places the clothes to the desired position, such as the material box on the robot AGV, the feeding port or the sowing wall, so that the single order cycle is completed.
By using the pick-up system, the clothes can be picked up at high speed, and the average beat of the mechanical arm 100 picking up one clothes through the sucker assembly 200 is 8S including the code scanning identification program. And the pick-up system has the advantage of small occupied space, and can reduce the reduction of the utilization rate of the goods shelf 400 to the minimum, the minimum space required for picking up clothes is 140mm high, and the data is simulated under the conditions that the quality of the clothes packaging bag is low, and the collapse height of the clothes after being grabbed is about 10 mm. The picking system is wide in application range, can adsorb goods made of different materials, particularly for goods packaged in soft bags, does not need to select a specific picking angle or a picking point, can smoothly complete picking when approaching, and is small in picking difficulty and high in picking efficiency.
