Frequently arising problems of production:

- A tear strip, lying outside the intended tear flaps, cannot fulfil the requested function
- Complaints boost production costs and decrease customer satisfaction

TSC - Tear strip control
control of absence or position of the tear strip

Hardware

image processing with 5,6’’ LCD-display

image processing controller with graphic user interface

image processing camera installed in a protection panel

signal lamps for faulty sheets

linear moving unit to adjust the camera position (option)

adjustment of the measuring position bv hand available

automatic positioning of the camera with a stepping motor

special illumination unit

aluminium panel (contains all control components)

marking unit as an option to mark faulty boxes

strong fixing system to fix the control cabinet close to the machine

Software

indication of the actual camera picture

counter for total, good and faulty sheets

input of limit values over the user interface

input of order-specific measuring positions (automatic positioning)

generation of an error-signal when measurement out of the limit values

reset of the permanent error indicator over the user interface

Properties

position control controls the absence and the position of the tear strip

accuracy +/- 0,5 mm

performance: up to 18.000 sheets per hour (more capacity on demand)

adapted for white and brown sheet surface

optical decoupled signals to connect a marking unit for faulty sheets

static error signal to stop the production (reset of the signal over the user interface or a separate switch)

Troubleshooting with TSC - Tear Strip Control:

The TSC-system checks the position of the tear strip on the sheet. If a tear strip is missing or lies outside of the set limits an error signal is generated. As example, this error signal can be used to stop the production in order to eliminate the error.

The TSC system provides you with the certainty of guaranteeing your customers a hundred per cent quality of the position of the tear strip.

The TSC system consists of a control housing with a monitor for the display screen, an operating terminal to run the system and lamps for the status display.

The picture for image processing is provided by a camera integrated in a protection shell. This camera is attached to a linear moving device, ensuring fast adjustment in case of an application change.
