Automatic Alignment and Positioning Method for Base Paper in Corrugated Board Production Line

Abstract

The invention discloses an automatic body paper alignment positioning method for a corrugated paper board production line. Microspur laser range finders, wireless data transceivers and single-chip microcomputer controllers are mounted on roll paper supports of all paper roll stations of the corrugated paper board production lines respectively; the microspur laser range finders transmit the measured data to a main control computer through the wireless data transceivers; before operation of the corrugated paper board production line, an operator sets paper roll positions of the main control computer according to widths of the paper rolls and a corrugating machine and required positions of the operation; the set data are sent to the single-chip microcomputer controller of the first paper roll station of the corrugated paper board production line; the single-chip microcomputer controller of the first paper roll station adjusts the paper roll positions in place according to the instruction of the main control computer, and the distance-measured data are sent to the main control computer; the main control computer transmits the received distance-measured data to the single-chip microcomputer controllers of other paper roll stations for laser ranging. The automatic body paper alignment positioning method for the corrugated paper board production line has the advantage that the automatic body paper alignment positioning of the corrugated paper board production line is achieved.

Description

technical field [0001] The invention relates to a corrugated cardboard production line, in particular to a method for automatic alignment and positioning of base paper in the corrugated cardboard production line. Background technique [0002] Corrugated cardboard production line is an indispensable main production equipment for the corrugated packaging industry, from single-corrugated cardboard production line to 3-corrugated cardboard production line, and the applied base paper also varies from 2 layers to 7 layers. Especially for double-corrugated cardboard and triple-corrugated cardboard, 5 to 7 layers of base paper are often used. These layers of base paper are distributed on a production line with a length of more than 100 meters, and each layer of base paper runs from the web support to the corrugated single-facer. The guide rollers, the preheater, the two guide rollers on the preheater, etc. have to go through multiple guide adjustments, and the heating roller on the ...

AI Technical Summary

Problems solved by technology

Therefore, a slight deviation in the positioning of the paper roll on the roll paper support of each station will cause a shortage of corrugated cardboard, and thus generate greater waste or even batch scrapping

At the same time, during the production of corrugated cardboard, the paper needs to be changed frequently, and after each paper change, since the chuck of the roll paper support enters the center of the paper reel freely, it cannot be guaranteed that the clamping position is the same every time, so it will A small amount of offset caused by the paper roll, if it cannot be found and corrected in time, will also lead to the scrapping of the produced cardboard

[0003] At present, the base paper alignment and positioning of the corrugated cardboard production line are all manually operated during the start-up operation, which is not only time-consuming and laborious, but also difficult to operate

Because the deviation can only be observed by pasting the paper together during manual operation, and then adjust the position of the paper roll on the roll paper support according to the deviation, which makes it often takes several minutes to ten minutes to adjust a paper roll. And each layer of paper has to run a distance of 30 to 100 meters to correct the deviation. It takes at least half an hour to adjust several layers of paper, and at the same time it causes hundreds of meters of paper waste. The amount of waste is not surprising.
