High-precision straight-line labeling machine

Abstract

The invention discloses a high-precision straight-line labeling machine. The high-precision straight-line labeling machine comprises a labeling head, a conveying device, a label inspection electric eye and an object inspection electric eye. Drive power of the labeling head is obtained through a stepping motor. The drive power of the conveying device is obtained through a servo motor. The high-precision straight-line labeling machine further comprises a PLC master controller. The PLC master controller starts the servo motor. The conveying device drives a labeled object to move through the servo motor. When the object detection electric eye detects that the labeled object passes by, the PLC master controller enters an external interruption subroutine, a high-speed counter is triggered and reads the pulse number output through a pulse output port of the servo motor. After the high-speed counter counts to the target value, the PLC master controller starts the stepping motor, and the stepping motor continues to move; and after the label inspection electric eye detects the gap between labels, the stepping motor is controlled to move by an assigned distance and then stops, and therefore the labeling function is achieved. By means of the high-precision straight-line labeling machine, the labeling precision is increased, stepless speed regulation is achieved, the speed can be rapidly switched to be matched with the production speed of a whole production line, and the production line can be efficient and smooth.

Description

technical field [0001] The invention relates to the technical field of product packaging, in particular to a high-precision linear labeling machine. Background technique [0002] For production enterprises that need product packaging, labeling machines are indispensable machines. The labeling machine is a device that sticks rolls of self-adhesive paper labels (paper or metal foil) on PCBs, products or prescribed packaging. Labeling machines are an integral part of modern packaging. [0003] The labeling machine is divided into a linear labeling machine and a rotary labeling machine. At present, most of the domestic labeling machines are linear labeling machines. The linear labeling machine is mainly composed of a labeling head and a conveying device. The linear labeling machine The driving power of the labeling head is a servo motor, the driving power of the conveying device is an AC motor, and the labeling error of the linear labeling machine at the same speed is ±1mm.
