Description

Technical Field

[0001] The invention relates to a corrugated cardboard production technology, in particular to an automatic interactive flipping, conveying and stacking device for corrugated cardboard. Background Art

[0002] The production of corrugated cardboard, from the roll of raw paper material to the output of finished cardboard, is difficult to accurately control due to the uneven moisture content of the material, the adjustment of the moisture content of the paste used for lamination and the amount of chemical additives, and the changes in the heating or humidification process in the production process. After the cardboard is formed and produced, during the static storage process, due to the influence of seasonal ambient temperature and humidity, the cooling process of the cardboard itself, and the different expansion and contraction of the internal layers of paper, different degrees of bending and deformation occur, and it is no longer flat, resulting in difficulties in subsequent processing procedures and reduced product quality. In order to keep the cardboard flat during storage after it is produced, the method used for a long time is to manually put down a small stack of cardboard (20-30 sheets) with the front side, and then turn the next stack over to the previous cardboard with the back side, and then keep the next stack on the original front side, and then stack it again with the back side, and store it in this alternating stacking manner. In this way, the bending force of the cardboard can be offset by the upward force and the downward force of the other stack after it is turned over, so that the cardboard will not be bent or deformed during storage. This stacking method is currently All of them are done manually, relying on a large number of manpower. For a high-speed automated corrugated cardboard production line, the entire line only requires 10-12 people, while the manpower for the paper collection part in the back section requires 5-7 people. Even in a high-speed production line with an average speed of 150m-min~200m / min, the manpower required in the back section will double to more than 10 people, that is, the manpower consumption is more than 50% to 70% of the entire line. At the same time, because manpower cannot run for a long time like machines, human fatigue will also become a limitation of speed and output, causing the back section of paper collection and stacking to become a bottleneck of the high-speed automatic production line; general manual flipping operation requires two people to stand on both sides of the conveyor belt, lift a small stack of cardboard, and then rotate 180 degrees on the spot, and then put it down on the conveyor belt for forward transportation. This operation requires two people to lift the cardboard stack together, causing the conveying speed to stagnate for a short period of time. When encountering a large-sized cardboard stack, it is heavier and lifting is often more laborious, and the delay time will also be longer; in short, the flipping and stacking of cardboard stacks are currently done manually, with very low efficiency, resulting in high production costs for enterprises.
