Intelligent and digital single-roller color code tracking device

Abstract

The invention discloses an intelligent and digital single-roller color code tracking device, which is used for tracking color codes in the packaging and bag making processes of plastic films and composite materials thereof and the like, and comprises an input display device, a digital control device, two speed-regulating devices, a photoelectric encoder and other components. During color code tracking, a color code signal generated by an actual color code position on a packaging bag instantly captures a coded value corresponding to the photoelectric encoder through the digital control device,the coded value is compared with a set coded value of the expected color code position corresponding to the photoelectric encoder in the input display device, color code tracking deviation is calculated, and the speed of a rubber roller is automatically regulated according to the color code tracking deviation. Therefore, speed difference is present between the rubber roller and a main (packaging)roller, and the delivery of the films is influenced through resistance by combining the action of a damping component; therefore, the color codes of the films are tracked. The tracking device overcomes the defects of the traditional electromagnetic clutch type color code tracking device.

Description

technical field [0001] The invention relates to a single-roller intelligent digital color mark tracking device, which is especially suitable for color mark tracking of small bag packaging equipment with single roller, fixed bag length and mass production. Background technique [0002] At present, for the single-roller color mark tracking device, the traditional "photoelectric clutch type" is used, and its main defects are: [0003] 1. The color code deviation detection and comparison system is relatively rough, the detected color code deviation cannot be quantified and displayed, and the on-site packers cannot intuitively perceive; especially, when the color code deviation is too large (the color code cannot be tracked normally) and the When it is a waste product, the machine will not alarm and will not stop. [0004] 2. No matter how much the color mark deviation is, as long as the machine runs stably, the adjustment amount is fixed each time when the color mark deviation ...

AI Technical Summary

Problems solved by technology

[0003] 1. The color standard deviation detection comparison system is relatively rough, and the detected color standard deviation cannot be quantified and displayed, and the on-site packers cannot intuitively perceive it; especially, when the color standard deviation is too large (the color standard cannot be tracked normally) and the produced When it is a waste product, the machine will not alarm and will not stop

[0004] 2. No matter how much the color mark deviation is, as long as the machine is running stably, the adjustment amount is fixed each time when adjusting the color mark deviation, so that the tracking of the color mark cannot be quickly realized

[0005] 3. The adjustment amount of the color standard deviation is related to various factors such as the size of the host (packaging) roller, the size of the rubber roller, and the size of the damping force, which is difficult for the on-site packers to grasp

[0006] 4. The effect of color mark tracking has high requirements for the cooperation between the length of the packaging bag, the size of the main machine (packaging) roller, and the size of the rubber roller. If the cooperation is not good, the color mark is difficult to track, or cannot be tracked at all

[0010] 2. Waste of packaging film and filling materials, resulting in low yield

This result is inevitable because the color scale is difficult to track

[0011] 3. The requirements for packers are relatively high and more operating experience is required

[0012] 4. Packers need to frequently observe whether the color mark tracking is normal, which consumes more labor
