The strip guide consists of a roller cage at the outlet of the straightening machine with integrated strip loop monitoring (strip too tight) via a dancer arm.
The ultrasonic loop control is housed in a separate enclosure with floor mounting option. Side guide rods guide the strip centrally over the ultrasonic head. An integrated ground contact stops the strip when it touches the base plate.
The loop control automatically regulates the main drive in a fast-slow manner, thus ensuring smooth strip running.
The strip guide is positioned between the straightening machine and the press and is designed as a double-sided roller cage in a closed construction. The rollers are mounted directly in the roller cages and ensure stable and precise strip guidance.
A mechanical, infinitely variable height adjustment allows adaptation to different press inlet heights, as required by changing tools.
A loop control is integrated via an ultrasonic sensor mounted between the two roller cages at the height of the connecting strips.
The sensor monitors the strip sag to both minimum and maximum values. In addition, the strip end is monitored.
The strip transfer table is located behind the straightening machine and is designed as a double-sided roller cage in a closed construction. The rollers are mounted in a special link chain.
Swivelling the link chain upwards creates a flat transfer surface. When swivelled down, it forms a radius that is designed for the maximum strip thickness. When swiveled up, both link chains are automatically raised to the same height, which enables smooth transfer of the strip from the straightening machine to the press.
A mechanical, infinitely variable height adjustment allows adaptation to different press inlet heights resulting from the use of different tools. Height adjustment is carried out manually via integrated jacking devices.
The strip transfer has an integrated loop control with a laser installed above the strip path between the two roller baskets. The strip sag is monitored for minimum and maximum values. In addition, the control system detects the end of the strip.
As standard, transfer is only possible if the strip is sufficiently rigid so that it does not sag over a length of 200 mm. The strip must also be able to slide over the necessary distance from the straightening machine to the feed.
The rollers of the link chain are plastic-coated to prevent strip damage. At the same time, the coating ensures smoother strip running.
Motorized height adjustment
The height adjustment is motorized. The infeed height can be read off the operating computer.
Belt side guide
In the middle of the belt transfer is a belt side guide, which consists of two vertical side guide rods and can be adjusted centrally via a spindle.
Strip loop monitoring
A dancer arm is attached to the roller basket, which monitors the strip loop.
If the loop is insufficient or an error occurs, the dancer automatically switches off the next machine.
Belt loop monitoring pit
The strap loop is monitored in the pit by a light barrier, which triggers the “Loop full” signal. This causes the straightener to stop and wait until material is removed from the loop again.
