At present, the storage and conveying part in the factory building has realized very high degree of automation, but in the step of loading, the degree of automation is not high due to the limitation of places, vehicles and the like, and most scenes still use manpower or simple mechanical power assisting equipment for carrying and loading. The defects of manual operation are that the labor intensity of personnel is high, the efficiency is low, and the loading quality is uneven. The existing automatic loading system mainly comprises a manipulator stacking mode, a lifting belt type stacking mode, a traveling gantry type stacking mode and other modes, and the modes have various limitations, such as: if the loading direction of the manipulator stacking is horizontal pushing, the maximum grabbing weight of the manipulator stacking is only 30kg; if the loading direction is vertical lifting, the manipulator is a multi-joint robot, and the joints of the manipulator need operation space, so that the top layer of the van cannot stack the packing box, or can only be applied to non-van with unrestricted top space.

The implementation process of the automatic packing box loading system of the utility model is that,

Information such as the length, width and height of a container of a cargo vehicle, the specification of the container, the stacking requirement of the container and the like is input into a PLC control system of the automatic packing container loading system, a packing scheme of the maximum packing quantity is obtained, the length of the container is taken as a step length, and a control program of the automatic packing container loading system for walking in the carriage of the cargo vehicle is set in a stepping mode.

Firstly, the automatic packing box loading system walks to the proper position at the innermost end of the van, and the specific position can be set in advance by the PLC control system and is measured by a distance measuring device arranged on the automatic loading system.

And then the position between the automatic loading system and the belt conveyor 6 matched with the automatic loading system is adjusted, the belt conveyor 6 is lifted to the same height as the conveying surface of the roller conveyor 2, and the conveying width of the incoming material packing box is aligned with one roller way of the No. 1 roller conveyor 2-1 and the No. 2 roller conveyor 2-2 with proper specification, so that the packing box is conveyed from the belt conveyor 6 to the automatic loading system.

According to a program set in advance in the PLC control system, the width or the height of the incoming material packing box is determined as the bottom surface contacted with the van during future loading according to the calculation.

If the calculated result is that the width of the incoming material packing box is taken as the bottom surface of future loading, the incoming material packing box directly walks to the front end of the No. 1 roller conveyor 2-1 by the telescopic belt conveyor and stops.

If the calculation result is that the height of the incoming material packing box is the bottom surface of future loading, the incoming material packing box walks to the rear end of the No. 1 roller conveyor 2-1 and stops, then the incoming material packing box is turned over to the No. 2 roller conveyor 2-2 by the box turning mechanism 2-3 arranged at the position, so that 90-degree turning of the incoming material packing box is realized, then a motor of the No. 2 roller conveyor 2-2 is started, and the incoming material packing box is conveyed to the front end of the No. 2 roller conveyor 2-2 and stops.

At this time, the suction cup mechanism 3 realizes the movement of the vacuum suction cup 3-6 through the driving of the transverse moving motor and/or the longitudinal moving motor and/or the vertical moving mechanism, the vacuum suction cup 3-6 is positioned right above the incoming material packaging box, the position can be detected and positioned by a distance measuring device and/or a visual perception system which are arranged on the vertical lifting mechanism 3-4, then the incoming material packaging box right below the vacuum suction cup 3-6 is adsorbed, and then the incoming material packaging box is driven by the transverse moving motor and/or the longitudinal moving motor and/or the vertical moving mechanism and is sent to the stacking platform 4.

The order of placing the incoming material packing boxes on the stacking platform 4 by the sucker mechanism 3 is from one side to the other side in the width direction, and the positions of the incoming material packing boxes are compactly stacked one by taking the width or the height of the incoming material packing boxes as step sizes. The placement position of the package is also measured and positioned by distance measuring devices and/or visual perception systems mounted on the vertical lift mechanisms 3-4.

After the sucking disc mechanism 3 repeats sucking and releasing actions for a plurality of times, a whole row of packing boxes are transversely stacked on the stacking flat plate 4-2 of the stacking platform 4. The stacking plate 4-2 is used as the working surface height of the stacking platform 4, and is not rigidly specified.

Then, the lifting push rod 5-2 of the lifting loading platform 5 is started, and the lifting push rod 5-2 drives the rigid chain type scissor fork operation surface to lift to be consistent with the working surface of the stacking platform 4 in height. Subsequently, the push rod mechanism 4-3 of the stacking platform 4 acts, the long push plate I is driven by the push rod 4-4 to push the whole row of packing boxes stacked on the stacking flat plate 4-2 to move forwards, the whole row of packing boxes finally fall onto the top plate 5-7 of the lifting loading platform 5, and the L-shaped push rod 5-6 is at an initial position (namely positioned at the rearmost end of the top plate 5-7) and is also positioned at the rear end of the whole row of packing boxes.

Then, the lifting push rod 5-2 of the lifting loading platform 5 is started to drive the lifting mechanism 5-1 to ascend or descend until the height of the bottom plate 5-5 is slightly higher than the height of the upper surface of the stacked packing box in the carriage after the last loading action is finished; the height can be measured and positioned by a distance measuring device mounted on the lifting loading platform 5.

Then, the bottom plate push rod 5-4 and the L-shaped push rod 5-6 drive the bottom plate 5-5 and the long push plate II to move forwards, and the long push plate II pushes the whole row of packing boxes which are already dropped on the top plate 5-7 to slide forwards; because the top plate 5-7 is fixed, when the bottom plate 5-5, the L-shaped push rod 5-6 and the whole row of packing boxes move forwards integrally, the bottom plate 5-5 is slowly exposed from the lower part of the top plate 5-7, the gravity center of the packing boxes is inclined along with the continuous forward pushing, the front end of the packing boxes falls on the bottom plate 5-5, and the bottom plate 5-5 is pushed along with the bottom plate push rod 5-4 until the packing boxes fall on the bottom plate 5-5 completely; at this time, the bottom plate 5-5 is positioned above the entire row of packing boxes that were last packed.

Next, the floor push rod 5-4 is reversely actuated to drive the floor 5-5 fixedly mounted thereon to move backward. Because there is the difference in height between bottom plate 5-5 and roof 5-7, roof 5-7 can stop the packing box and remove backward along with bottom plate 5-5 at this moment, and when L shape push rod 5-6 returns to initial position, bottom plate 5-5 also takes out completely from the packing box bottom, and the packing box naturally falls on the whole row of workbin of last vanning.

4. The strength of grabbing the packaging box by the vacuum chuck is high, so that 100kg of packaging boxes can be grabbed;

5. Because the vacuum chuck grabs the packing box from the top, compared with the mode of grabbing or clamping the side face of the manipulator, the vacuum chuck has the advantages that the packing box is not easy to break;

6.
