Labeling machine through vacuum drum

Abstract

A labeling machine through a vacuum drum is composed of a rack, a collecting conveying line, a paging mechanism, a vacuum adsorption part, a labeling mechanism and a corresponding control part and is characterized in that when paged by the paging mechanism and then adsorbed on a vacuum drum device, paper is saw by an object detection sensor during rotating and labeled by the labeling mechanism; and after being labeled, the paper is separated by a blanking device onto the collecting conveying line and conveyed into a collecting box by the conveying line. The labeling machine through the vacuum drum has the characteristics of being high in labeling precision and wide in application range.

Description

[0001] This case is a divisional application, the original application number: 2014104566282, the original application date: 2014-09-04, the original invention name: a vacuum drum pagination labeling machine. technical field [0002] The invention relates to a vacuum drum labeling machine. Background technique [0003] As we all know, in the labeling industry, in order to achieve the labeling accuracy, the self-adhesive labeling machine requires the labeling of objects of various shapes to be synchronized with the labeling speed. When being labeled, the walking speed must be stable and must not swing, otherwise it will not meet the labeling accuracy requirements. Therefore, in order to improve the precision, people have made various fixtures to fix objects with shapes such as containers, boxes, and bottles. However, it cannot be fixed for shapeless paper, especially thin paper, which cannot be fixed or positioned. Someone made a vacuum adsorption method at the lower part o...

AI Technical Summary

Problems solved by technology

However, the conveyor belt vibrates and shakes during transmission, causing the paper to run unstable on the conveying line, and when the speed is high, the edge is prone to air leakage, which makes the vacuum suction insufficient, and the paper is easy to float and cannot be labeled.

When the speed is low, it is easy to misalign left and right, the error of labeling accuracy is large, and the labeling is not firm, and the thinner the paper, the more unstable

Therefore, it is very difficult to achieve the ideal labeling on each paper
