A high-precision material receiving device and method

Abstract

The invention discloses a high-precision material receiving device and method. The material splicing device in the present invention includes a new material roll, an old material roll, a feeder, a cutting and pasting mechanism, a pair of front pressing rollers, a pair of rear pressing rollers, a first photoelectric positioning sensor and a second photoelectric positioning sensor. The splicing method in the present invention includes a preparation splicing stage, a splicing alignment stage, a splicing progress stage, and a splicing completion stage, wherein a high-precision splicing algorithm is adopted in the splicing alignment stage, and the The distance of the new roll to be spliced ​​can achieve high-precision splicing of printed patterns. The invention adopts the double-station alternating operation mode, which speeds up the switching speed of the old roll and the new roll, saves a lot of labor costs, and avoids the consumption of materials, so that the front-end technology of the packaging and printing process is improved.

Description

technical field [0001] The invention belongs to the technical field of flexible packaging machinery and control, and relates to a high-precision material receiving device and method. Background technique [0002] In my country's flexible packaging industry, the packaging and printing industry known as "urban industry" has become one of the most growing industries in recent years, and has continued to grow at a rate of 10% to 12%. However, most of the small and medium-sized packaging and printing enterprises, due to lack of funds, mostly use low-to-medium packaging machinery and equipment. Many packaging and printing companies buy second-hand imported packaging machinery and equipment, many small-scale enterprises use old-fashioned equipment, and the post-press production equipment is relatively backward, and some post-press equipment is almost aging. [0003] General packaging machinery and equipment are equipped with an unwinding mechanism, and the form of manual roll chan...

AI Technical Summary

Problems solved by technology

For enterprises, firstly, it increases the labor cost, and secondly, the production capacity cannot be improved, especially for printing patterns with periodic pitch lengths. Manual is not only to unload and load the material rolls, but also to face pattern splicing. The problem is how to ensure that the pattern of the cut part of the old roll can be spliced ​​with the pattern of the cut part of the new roll

At present, there is no suitable solution to this technical problem, and still rely on manual splicing, which will lead to the problem of inaccurate splicing and the problem of splicing efficiency; inaccurate splicing will cause waste of materials, and the waste of materials can reach several Ten meters or even hundreds of meters; and the efficiency of splicing is caused by the proficiency of technicians, which will increase the labor cost of the enterprise
