The working process of the intelligent dustproof unpacking quantitative feeding system is as follows:
firstly, placing a pallet filled with a bagged powdery material bag 19 in a station of a grabbing operation area of an industrial robot 2;
secondly, scanning the position and the stacking condition of the powder material bag 19 packaged on the pallet by a scanning device 17 to guide the industrial robot 2 to grab the bag;
step three, the mechanical arm of the industrial robot 2 moves to the position above the bagged powdery material bag 19 to be grabbed, and the image recognition system 6 recognizes the bagged powdery material bag 19 to determine the grabbing position;
fourthly, the vacuum chuck 4 and the grabbing hook 5 on the industrial robot 2 grab the bagged powdery material bag 19 according to the position determined by the image recognition system 6;
fifthly, the industrial robot 2 transports the bagged powder material bag 19 to a certain height above a hopper 11 and an unpacking cutting edge 12 of the unpacking quantitative feeding system 9, the force sensor 8 records the weight of the grabbed bagged powder material bag 19, then the vacuum chuck 4 and the grabbing hook 5 release the bagged powder material bag 19, and the bagged powder material bag 19 falls onto the unpacking cutting edge 12 in the hopper 11;
sixthly, after the bagged powder material bag 19 falls onto the unpacking blade 12 in the hopper 11, the unpacking blade 12 rotates or moves transversely and vertically to cut the bottom of the bagged powder material bag 19;
step seven, grabbing the unpacked material bag by a grabbing hook 5 on the industrial robot 2, shaking the material bag left and right and back and forth while grabbing the material bag, and enabling all the powder materials in the material bag to fall into a hopper 11; dust generated during unpacking is pumped away by a dust exhaust fan 22 of a dust exhaust device 21 above the hopper 11;
step eight, sensing the weight of the empty material bag by a force sensor 8 to judge that all the materials in the material bag fall into the hopper 11, and putting the empty bag into an empty bag recovery frame 20 by a mechanical arm;
step nine, recording the weight of the material bags grabbed by the industrial robot 2 and the quantity of the material bags thrown and placed by the unpacking quantitative feeding system 9 by the system, and calculating the quantity of the materials stored in the hopper 11 and the spiral conveying device 13 so as to judge whether the next unstacking and bag grabbing operation is continued or waiting; when the residual materials in the hopper 11 and the spiral conveying device 13 are less than the rated quantity, the industrial robot 2 continues to unstack and grab the bags;
step ten, conveying the material falling into the hopper 11 to a discharge port by a spiral conveying device 13, and falling into a weighing and quantitative feeding device 15;
step eleven, when the weighing sensor senses that the material in the weighing quantitative feeding device 15 reaches the set feeding amount, starting a cylinder 23 in the weighing quantitative feeding device 15, and pushing all the material in a piston track trough 25 into a feeding port by a piston 24 of the cylinder 23 to feed the material; the rotating speed of a servo motor 14 of the spiral conveying device 13 and the working rhythm of a cylinder piston 24 are adjusted, and quantitative feeding of the system is realized.
