COPRA® DecalApplicator:
Versatile heat release machine for 
table ware and tiles   

 

A new dimension in heat release transfer application

The industrial use of heat release decal application machines has been restricted by tolerances of both – decal as well as article to be decorated.

Factors like inaccuracies from cutting the decals to size, as well as alignment deviations during transfer application or article’s deviations from original size/shape resulted in increased expenditures in the decorating process.

data M’s new Heat Release Decal Application Machine is able to handle these restrictions – due to a silicone pad moved by a hexapod mechanism allowing an absolute free 3-dimensional movement.

Neither article nor decal has to be aligned any more. The silicone pad is able to compensate for every possible misalignment by respective movements.

 
Design
The silcone pad is attached to a platform beeing moved by six linear axes in hexapod formation. This allows an absolute free 3-dimensional movement in order to decorate also non-symmetrical or elliptical objects.

HexaControl software by data M for easy operationAC-servo-motors are driving the platform by means of ball screws. The achievable pressure is 25 kN.

Two computers are controlling the machine. One is used for the motor control, the other for the convenient user interface.
The pad is warmed up by infrared heater. A conventionally heating surface is used for the vacuum table

Workflow

The pad of the COPRA® DecalAppli-cator is moving from the heating station, where it is heated consistently by uniformly distributed infrared radiators, to the heated vacuum table, where a decal is already applied – loaded from magazine.

The actual position and shape of both, white ware as well as decal is detected by an integrated vision system. In the next step the printing pad is moved by the control computer in order to take the decal from the vacuum table and applicate it onto the white ware – perfectly matching.

Then the decorated workpiece is either moved to a storage magazine connected to the transportation belt or alternatively returned to a loading station.

Simultanuously the paper carrier is blown off the vacuum table and a new decal loaded from the magazine in order to decorate the next plate.

Setup

The setup for a new article is very easy: the user just selects a new program 
from the user menu. The pad can be ex-changed without tools using a quick-
release fastener.

This takes only a couple of minutes – even with completely new articles!

 

Service

data M Engineering is developping your pads with the aid of a FEM computer 
program and is manufacturing aluminium casting moulds up to 400 mm diameter. The pads are casted under vacuum and bonded to aluminium adapter plates with centering device tor the DecalApplicator.
