Unwinding module is designed for unwinding of laminate tape, for its steering, for the cutting of the necessary width and for the easy feeding of material to body-maker.
The purpose of the Unscrewing mechanisms is to provide a swift and even unwinding of the foil from the main roll.
Like an option the machine is provided with two places for laminate rolls.
Its helps prevented when the one finished.
The unwinding module has some basic mechanisms:
In the rear of the module:
The unscrewing roll is the first mechanism for unwinding the foil.
When the rolls are two we have a faster process to change the foil from one to second roll.
The table for foil connection serves for facilitating of the sticking of the laminate tapes.
The machines with two rolls, the table is hanged on an axle and has two fixed positions. Each position is purposed for one of the two rolls.
The function of tension regulator-
Stretcher I (P1) is to provide constant tension on the foil.
The optical sensor mounted on the mechanism used to switch on/off electromagnetic brake.
The regulating mechanism is designed to lead the edge of the foil incessantly on one and the same spot towards the cutting knives as the size of the tube is strictly defined and in order for a quality welding to be obtained an additional cutting of the foil is needed.
Knifes block consists of two parts
Push-button bushing with retaining knife and knife-holders.
Push-button bushing with retaining knife and knife-holderspresents a support construction on which there are attached two knives which may be tuned by the four axles so that a tape with width one millimetre at least to be cut.
The dragging mechanism is the latest mechanism in the unscrewing module. It’s function is to drag the foil by two bushes, one of witch is with rubber coating. The other bush is driving by motor in the rear of the module.
The Speed regulator – Stretcher II (P 2) is designed to control the speed of foil by Dragging mechanism. The flag with special contour and the Ultrasonic sensor on the rear side allow the foil to move with linear speed in dependent of BODYMAKER’s speed.
In the rear of the module over the same axle an electrical magnet brake is mounted which guide is implemented by an electricity switch A38/A39, increasing the signal from the optical sensor S06 and the flag to it mounted on the axle of the lever with the stretching roll.
The nozzle for leading away of the foil is situated under the knives and sways the cut thin tapes with the help of air under pressure. The starting and the stopping of the air is implemented with the help of electromagnet valve.
The sensor agglutination is mounted above the last roll of Unwinding module. His function is to “see” the scotch tape in the place where the laminate foil is connected.
This information is necessary to separate bodies with scotch like bad.
Switch on/off keys for pneumatic cylinders on the first/second connection table
Switch on/off keys for pneumatic cylinders on the first/second unscrewing rolls
There are two kind of control panels, in depending of number of rolls.
