Description

Technical Field

[0001] The present invention relates to the technical field of automated production line equipment, and in particular to an integrated production line for weighing and shaping packaging boxes. Background Art

[0002] In various physical commodity production enterprises, many products need to be packaged and packed in boxes before leaving the factory. The packaged products need to undergo appearance inspection and weighing, and can only be shipped out after passing the inspection. In production factories, the production volume of the same batch of goods is usually relatively large, which requires a large number of appearance inspections and weighing operations for boxes and cases. Currently, in many production factory workshops, the appearance quality inspection and weighing of boxes are usually carried out on a relatively simple production line. Cameras and other equipment are used for photographing and scanning. When the quantity of products is large, some boxes will inevitably be skewed in shape and unqualified in weighing. Moreover, the inspection volume of each batch of goods is huge. Therefore, it is very necessary to design a relatively complete inspection production line, which can greatly improve the inspection efficiency. Summary of the Invention

The structures of each lifting double-row belt conveyor are basically the same.

[0031] The technical solution of the present invention is a fully automated circular production line designed for the appearance inspection and weight weighing of a large number of packaging boxes. Its layout is shown in the appendix Figure 1 As shown, in the application process of the present invention, the specific process is carried out as follows: One loading worker is arranged at each loading station to load the corresponding packaging boxes one by one onto the line. The staff sends the boxes up through the first double-row belt conveyor, and the control device controls its operation. When the box reaches the lifting double-row belt conveyor, it rises to catch the box and conveys it horizontally to the second double-row belt conveyor, and so on for forward conveyance until it reaches the transfer conveyor line, and is transferred to the weight detection station through the transfer conveyor line for weighing here. Those with appropriate weight continue to be conveyed forward. Those with too large weight or inappropriate box size are conveyed in the direction of the conveyor and transferred to the size and weight difference abnormal processing area 8 for the staff to handle. After being processed and qualified here, they are then transferred back to the normal line; the weighed boxes continue to be conveyed forward to the shaping station. On the shaping station, the boxes are clamped neatly by the shaping cylinders and shaping plates on both sides along the line. The boxes are clamped straight and flat, and then continue to be conveyed forward to the appearance inspection station. Here, the appearance inspection camera moves on the sliding support rod above and takes pictures of the boxes from top to bottom for inspection, and transmits the appearance image to the background monitoring. Then the boxes continue to be conveyed forward to the sterilization code spraying station, where two groups of sterilization code spraying devices perform sterilization code spraying operations on the outer wall of the box. Then, four industrial code reading cameras read the bar code information on the box and transmit it to the background monitoring. Those with abnormal code spraying or code scanning reach the manual processing station, and the worker can perform code scanning processing again; finally, the boxes reach the box shipping station one by one, and are conveyed out through a longitudinal shipping double-row belt conveyor 23 and two transverse shipping double-row belt conveyors 24, completing the entire set of processes. The entire production line can operate continuously in one line with extremely high efficiency.

[0032] In the solution of the present invention, the structures of all double-row belt conveyors are the same. Two conveyor belts are arranged in parallel side by side, and a servo motor and pulleys are used to drive synchronous operation. The box is placed on the two conveyor belts and runs forward.

[0033] In the present invention, by designing a whole continuous feeding line, transfer conveyor line, weight detection station, shaping station, appearance detection station, sterilization code spraying station, four-sided code scanning station, manual processing station and box shipping station, a series of automated operations from large-batch feeding to weighing, box appearance detection, shaping, sterilization code spraying, code scanning, etc. are fully realized, with extremely high work efficiency, providing a strong guarantee for coping with the large-batch shaping and shipping of packaging boxes. In the solution of the present invention, the appearance detection, shaping and weighing of packaging box products are particularly efficient. It can not only realize one-stop operation on the automated production line, but also implement manual abnormal processing for abnormal packaging boxes among them. For abnormal workpieces with over-tolerance in size and weight, it can also perform emptying and buffering processing, with a comprehensive design. The entire system of the present invention adopts a circular layout design, with a relatively compact structure, and can realize large-batch pipeline operations on a relatively small space site, having good practical use and promotion value.
