A material image positioning control method

Abstract

The invention relates to a material image positioning control method. The material image positioning control method comprises the following steps: step 1, arranging an image control system on a conveying mechanism; step 2, when the conveying mechanism starts running and a high-speed camera obtains a signal of each product, and according to a set standard speed parameter, simulating a virtual product moving diagram via a single chip microcomputer; and step 3, comparing a photographed pattern and a standard pattern, when an error value between the photographed pattern and the standard pattern is greater than a set standard, since a product has already moved for a certain distance on the conveying mechanism, obtaining the coordinate position of the product via a controller, and comparing the above coordinate position with the coordinate position of the virtual product walking diagram, and if the error value is beyond a set standard error range, performing control via a motion controller, and matching the coordinate position in product actual moving to the coordinate position in standard product moving.

Description

Technical field [0001] The invention relates to the field of disposable absorbent article equipment, in particular to a material image positioning control method. Background technique [0002] At present, in the production process of diapers and pull-up pants, in order to make each material have a complete model or a complete pattern, mechanical adjustment rods or color mark sensors are often used for positioning. However, mechanical adjustment often has a long debugging cycle, and the color mark sensor cannot accurately capture the color mark when positioned at high speed, which will easily cause the high and low speed materials to deviate and become unstable, which will eventually lead to a large increase in the defective rate of the product and reduce the production efficiency of the equipment. . Especially in the processes that need to be cut in the production process of diapers and pull-up pants, once errors occur, the cutting will be inaccurate, and the products will be co...

Problems solved by technology

However, mechanical adjustment often has a long debugging cycle. The color mark sensor cannot accurately capture the color mark when it is positioned at high speed, which will easily lead to deviation and instability of the high and low speed material position, which will eventually lead to a great increase in the defective rate of the product and reduce the production efficiency of the equipment.

Especially in the process of cutting in the production process of diapers and pull-up pants, once an error occurs, the cutting will be inaccurate, and the product will be continuously scrapped
