Definitions
- the invention relates to a device for regulating the transport speed of band-shaped material.
- Known winding devices in particular those of magnetic tape devices, work mainly with electronic speedometer systems. They are particularly suitable because of the mostly electrical drives of the winding bodies.
- a subsequent differentiation of the Rectangular voltage and further pulse shaping of the pulses thus obtained supplies a rectangular voltage with the frequency of the copper flags passing the magnetic core.
- An electrical integration of this voltage forms an output signal which is proportional to the speed of the rotating body driven by the belt and which is fed to a control amplifier. From a target-actual comparison using a comparator circuit, this forms a voltage signal which acts on the electrical drive of one of the winding bodies via an amplifier (Philips paperback for electronic measurement technology, Franzis-Verlag, Kunststoff, 1st edition 1960, page 69) .
- a major advantage of the proposed solution lies in the simple construction of the control loop, whereby commercially available components can be used for all functional elements. Another advantage can be seen in the fact that with a pneumatic winding drive, the compressed air available for the energy supply can be used for the operation of the control circuit. Furthermore, electrical or magnetic interference fields cannot affect the control.
- a roller 1 is rotatably mounted on an axis.
- the band-shaped material to be transported from the unwinding side to the rewinding side - referred to below as band B - is guided over the roller 1.
- the tape B can be made of different materials, for example paper, plastic film coated and uncoated, metal, textile fabric or the like.
- a speedometer disk 2 made of metal or plastic is attached to one of the end faces of the roller 1, the circumference of which is arranged at a short distance from a pneumatic fork barrier 3.
- the fork barrier 3 is slidably mounted in the direction of the disk circumference, so that a distance between 1.0 mm and 20 mm can be set.
- the jet and catch nozzle of the fork barrier 3 are connected to a low-pressure booster 4, which detects the dynamic pressure which arises between the jet and catch nozzle via the compressed air supply to the fork barrier 3.
- the output of the low pressure amplifier 4 controls a high pressure amplifier 5, the one pneumatic turbine 6 for driving the unwind body supplied with compressed air.
- a pneumatic turbine is also provided for the winding body (not shown in the drawing), the torque of which is such that the winding of the tape B can keep pace with the unwinding, but the influence on the unwinding speed caused by the tape tension is negligibly small , ie that in the state of equilibrium which arises between the forces or moments, the desired speed of the belt B remains in the predetermined tolerance range.
- control loop The parts forming the control loop are commercially available pneumatic components; a profiled disk or a disk with elevations should be used for the speedometer disk 2 to generate the radial air flow.
- the speedometer dial 2 Due to the moving belt B, the speedometer dial 2 is rotated via the roller 1.
- the air sucked in under the effect of the centrifugal force in the center of the speedometer disk 2 and flowing radially outward hits the compressed air jet between the jet and collecting nozzle of the pneumatic precharge 3, which is preferably from the low pressure booster 4 with compressed air between 1.0 mbar and 2.0 mb 1.6 mbar.
- the compressed air jet is thus depending on the set distance between the circumference of the speedometer dial 2 and fork barrier 3 more or less deflected so that the dynamic pressure transmitted from the fork barrier 3 to the low-pressure booster 4 changes.
- This pressure change acts on the control input of the high pressure booster 5, which amplifies the changed compressed air 1.5 times to 4 times, preferably 3 times, in accordance with the gain factor of the low pressure booster 4, which is expediently between 400 and 600, preferably 500 the unwinding turbine 6 delivers.
- the speed of the turbine 6 is reduced or increased in this way as a function of the speedometer dial speed.
- the tape speed decreases during the rewinding process, e.g.
- the rotation of the speedometer disc 2 and with it the radial flow of the air also slow down.
- the compressed air jet between the jet and the catch nozzle is deflected less.
- the pressure at the input of the low-pressure booster 4 becomes higher, so that the drive turbine 6 is accelerated with the aid of the subsequent pressure booster.
- This constant control keeps the belt B at the set speed.
- the desired belt speed can be continuously adjusted by moving the fork barrier 3.
- the winding side can also be regulated in the manner described.
- Such braking devices are for winding Devices known in numerous embodiments, but firmly adjustable as well as controllable, so that the person skilled in the art will readily be able to make the appropriate application after suitable selection. It is entirely possible to control the braking device with the aid of the device according to the invention for the drive control via further pneumatic amplifiers or reversing elements and, if appropriate, via converters for the manipulated variable.
