The working principle is as follows:
S10, preparing a transport vehicle to enter the loading area 110, placing the loading bin 400 in a closed state, sliding the loading robot 300 on the pulley rail 123 until the position of the loading bin 400 is matched with the loading target position of the transport vehicle, and placing the swing conveying line 340 in a high position.
S20, starting feeding, namely feeding the material 900 into the waiting conveying line 210 by an external mechanism, and enabling the waiting conveying line 210 to operate so that the material 900 reaches the discharging conveying line 220 through the transition section 230.
S30, entering the loading robot, wherein when the material 900 reaches the redirecting mechanism 310, the material 900 is forced to change direction and enter the transfer conveying line 320.
S40, entering the loading robot, namely, after the material 900 runs to the end of the transfer conveyor line 320, entering the swing conveyor line 340 through the sliding slope 330.
S50, reaching the loading bin, namely, enabling the material 900 to enter the loading bin 400 from the feed inlet 440 by means of inertia transported by the swing conveying line 340.
In this step, the head of the material 900 may strike the back plate 422, which may be adjusted if the attitude of the material 900 is not a very standard.
S60, accurately adjusting the position and the posture of the loading bin, wherein the method comprises the steps of S61-S66;
S61, the loading bin 400 is positioned right above a loading target position through horizontal two-dimensional adjustment, specifically, the first step is that the swing frame 309 rotates along the vertical shaft 308 to adjust the transverse (left and right directions of the vehicle) position of the loading bin 400, the second step is that the loading robot 300 slides on the pulley rail 123 to adjust the longitudinal (front and rear directions of the vehicle) position of the loading bin 400;
s62, paying off the electric hoist 343, swinging the head of the conveying line 340 to fall, and driving the loading bin 400 to fall to reach the height of the loading target position;
In the above-described process, S63, the loading bin 400 is kept in the horizontal posture, and at this time, the horizontal posture of the loading bin 400 may not be aligned, and for this reason, the horizontal posture of the loading bin 400 is corrected by the rotation of the rotating portion 352 relative to the fixed portion 351.
It should be noted that, after the above step S50, if the posture of the material 900 is still not very standard, it will be observed by the camera 344, and in step S63, the horizontal posture of the material 900 in the loading bin 400 is correct by the rotation of the rotating portion 352 relative to the fixing portion 351.
At this time, the position and posture of the material 900 are in the correct position.
And S70, opening the two opening and closing plates 420 of the loading bin 400, and enabling the material 900 to fall into the loading target position of the transport vehicle from the gap between the two opening and closing plates 420.
The application is characterized in that:
s1, the loading bin is arranged, when the loading bin is closed, materials are not yet reached, the material is not damaged due to the action of closing the bin door, and the loading is convenient.
S2, the whole system is located above the loading area 110, and compared with side loading, the occupied area is reduced, and the vehicle is convenient to reverse and the like.
S3, the whole main conveying line 200 is U-shaped, and under the condition that the main conveying line is kept to be matched with the loading length, the length of the main conveying line 200 is long, the waiting conveying line 210 can be used as a material preparation area, and material congestion is prevented.
S4, because the length of the transport vehicle is longer, when the redirecting mechanism 310 intercepts materials, the materials can be approaching or can be backward, and because the blanking conveying line 220 is parallel to the pulley track 123, the redirecting mechanism 310 moves back and forth, so that the intercepting of the materials is not influenced.
