Manual swivel
The reel is swiveled and locked manually.
Motorized swivel
The reel is swiveled by a geared motor.
An additional rotary encoder enables the swivel to be used as a positioning axis.
This enables smooth acceleration and braking of the reel.
The end position is locked pneumatically.
Manual spreading
Manual spreading is performed using a hand crank that acts via a joint lever.
Hydraulic spreading
The spreading is done hydraulically using sliding wedges, supported by a pressure accumulator and a switchable automatic tensioning device. This design allows for reduced spreading force while increasing stability thanks to a large contact surface.
Pneumatic brake
The reel is braked pneumatically using powerful, double-bearing disk brakes. The friction pads are articulated to ensure that they are applied over a large area and to prevent them from running off at an angle.
The large brake disk diameter and the arrangement of the brake disk outside the reel head offer several advantages:
- low braking force
- Low heating of the brake
- easy accessibility
The continuous brake is adjusted via a pressure control valve
Regenerative brake
The drive via a high-quality three-phase geared motor with digital control is used for feeding into the straightener as well as for rewinding and braking the strap.
The transmission from the motor to the coiler shaft takes place via a spur gear. A brake attached directly to the drive motor is used to safely stop the drive when the control voltage is switched off.
The retraction force of the reel is entered in the control panel, stored and controlled by a laser depending on the diameter.
This keeps the retraction force of the straightener virtually constant.
Drive
A three-phase geared motor is used as the drive for unwinding the belt and as an auxiliary drive for feeding in the belt. The drive is controlled via a frequency converter.
A brake attached directly to the drive motor is used to safely stop the drive when the control voltage is switched off.
Protective ring
The protective ring is designed as a closed ring made of tubular steel and is connected to the pivot bearing by sturdily dimensioned struts.
Rear push-on arms
3 slip-on arms prevent the coil winding from falling sideways.
The push-on arms have a quick clamping mechanism.
Counterholder
A counterholder, which is attached after the coil has been placed on, prevents the coil winding from falling down sideways.
It is designed as a closed ring and equipped with a quick-release clamp.
Front clip-on arms
3 push-on arms, which are attached after the coil has been placed, prevent the coil from falling sideways.
The push-on arms have a quick clamp.
Start-up and back-up rollers
Three fixed conical rollers serve as the rear coil system instead of the traveling protective ring. The counter-holder rollers are swiveled in hydraulically and moved to the coil width by motor.
This arrangement makes it possible to drive narrow and thick strips safely into the straightener with the help of the pressure roller.
The minimum strip width without backing rollers is 80 mm, with backing rollers the minimum strip width is 20 mm.
Belt center adjustment via spindle
The belt center is adjusted manually via the spindle by moving the reel.
The protective ring serves as a contact surface. When loading, ensure that the coil is always in contact with the protective ring. The belt width can be read off a scale on the base frame.
Motorized strip centering
The strip center is adjusted by a motor with an absolute encoder via a spindle by moving the reel. The protective ring serves as a contact surface.
During loading, it is important to ensure that the coil always rests against the protective ring.
The strip width can be read digitally on the operator display and stored in the tool data memory.
Strip pressing device without drive
The pneumatically operated strip pressure device prevents the strip from springing open when the bandages are opened, thereby eliminating the associated hazard.
The arm width is approx. 40 mm. This results in a minimum strip width of 40 mm that can be threaded with the pressure arm.
The pressure arm is mounted in a robust console that is attached to the reel housing.
The pneumatic cylinder is equipped with seat valves that reliably maintain the pressure in the cylinder in the event of a hose rupture.
Strip pressing device with drive
The hydraulically operated strip pressure device prevents the coil from springing open when the bandages are opened, thereby eliminating associated hazards. Both the speed and the contact pressure can be individually adjusted.
During rewinding, the pressure roller acts as a brake, while during winding, tension is applied to the material. The driven pressure roller also serves to advance the start of the strip and to rewind it.
The arm width is min. 80 mm. In conjunction with the start-up and counter-holder rollers, the arm width is approx. 160 mm.
This results in a minimum strip width of 80 mm for the standard coil guide and 20 mm for the start-up and counter-holder rollers, which can be threaded with the pressure arm.
The pressure arm is mounted in a robust bracket that is attached to the reel housing.
The seat valve mounted directly in the hydraulic cylinder provides additional safety. This reliably maintains the pressure in the cylinder, even in the event of a hose rupture.
Fixed coil loading chair and cross travel device
The coil loading chair is located outside the coil run, is hydraulically height-adjustable up to the smallest coil outer diameter and is permanently installed in the floor. The coils placed on it can be easily picked up from the decoiler.
For safety reasons, large coil weights cannot normally be loaded without a coil loading chair.
The coiler is equipped with a cross travel device. It is used to automatically align the coil in the center of the straightener infeed and to pick it up from the fixed coil loading chair. It is driven by a three-phase geared motor.
Mobile coil loading chair
The coil loading chair is located outside the coil run, is hydraulically height-adjustable up to the smallest coil outer diameter and is mounted on a traversing device. The coils placed on it can be easily transported to the decoiler.
For safety reasons, large coil weights cannot normally be loaded without a coil loading chair
Fixed scissor lift table and cross-travel device
The scissor lift table is located outside the belt run, is hydraulically height-adjustable up to the smallest coil outer diameter and is mounted on a traversing device.
The coils placed on it can be easily transported to the decoiler.
For safety reasons, large coil weights cannot normally be loaded without a coil loading chair.
Mobile scissor lift table
The scissor lift table is motorized, hydraulically height-adjustable, and mounted on a travel device. This allows the coil to be loaded outside the working area and then easily transported to the reel.
For safety reasons, large coils cannot normally be loaded without a coil loading chair, as the lifting gear does not fit into the recess of the reel spreader.
Top jaws
The clamping range can be extended using top jaws.
Base frame
The straightener and reel are mounted on a common base frame.
This eliminates the need for additional floor fastening as the tensile force of the straightener is transmitted within the base frame.
The base frame is positioned on the floor using height-adjustable feet. This allows the machine to be precisely aligned without great effort.
