Definitions

  • the invention relates to entrainment systems in a device for pulling or braking of metal strips or sheets, preferably in strip lines between endless revolving chain systems.
  • the invention is based on the problem, on the one hand the possible uses to expand the known brake scaffold and on the other hand in particular for the entry, exit and entrainment conditions of the carriage-like Roller blocks in the conveyor area are targeted, for the different tasks to achieve different behavior.
  • This problem is solved according to the features of the main claim solved a shape that has a stable support in the central area causes.
  • the inlet and outlet must be made elastic. Training takes place so that a high elasticity in the horizontal direction (Tape direction) is reached. Furthermore, with the invention little crushing is achieved, which makes the flexing work in and Spout can be significantly reduced.
  • the coating width corresponds to the chain pitch. The arrangement is between the Running coils. With this training it is possible to have a closed contact surface is available in the take-away area. This training requires the synchronous running of the upper to the lower car chain.
  • a low hardness of the coating is preferably relative to a thick coating selected.
  • the metal tape is embedded so that the shape defects of the metal strip in cross section and the band ripples can be easily compensated.
  • the open spaces created allow that the squeezed volume of the elastic coating flow specifically can.
  • the coating receives a filler, e.g. a flat steel. This will achieved that the squeezing by means of the form factor of the functional task can be adjusted while the desired inclination the coating in the direction of pull can be done almost without restriction.
  • a filler e.g. a flat steel.
  • a sensible application is that only one rotating Carriage chain, is designed as a revolving table. In doing so forces into it by means of permanent magnets or electromagnets Belt initiated to apply braking or tensile forces. magnetizable Metal tape is attracted to the Protective belt of the car chain pulled and it will be according to the ⁇ -value driving forces generated.
  • the heating of metal strip is achieved when the energy is above that circulating system is supplied conductively or inductively. This effect can also be used in galvanic or other processes.
  • the circulating system is equipped with electronic measuring heads For example, the strip thickness, the surface quality, the metallic structures and the like are checked very precisely, since the metal strip and the test head are used for a certain time identical speed can work in a fixed position.
  • the brake scaffold or the control frame can be around a belt tension measuring frame be expanded. Here these aggregates hang in leaf springs.
  • the reaction forces of the strip tension are falsified using measuring cells detected. This measuring system is only able to measure horizontal forces with high repeatability, and, depending on the measuring range, can be set to a few Newtons.
  • Strips such as copper or aluminum strip
  • special effects possible by the targeted feeding of the Chains with the roller blocks in a relatively short clamping and driving area by means of straight guide rails, which at the same time support allow the clamping forces.
  • Through inlet and outlet curves on the straight guide rails of the The targeted feeding of the roller blocks is achieved.
  • a special shape enables a very elastic transition. Squeezing is done by inserting shaped sheets the elastic coating is specifically reduced.
  • the design of the electric linear drive has the advantage that Load the hinges of the chain trolley straps only from the Deflection and centrifugal forces take place while the loads are being applied Belt pulls only work in the driving area.
  • the dimensioning the hinge can thus be limited to the deflection and centrifugal forces become. This minimizes wear.
  • the driving distance can be designed so that the metal belt conductive or inductive current is supplied.
  • This solution comes preferably in galvanic processes, when the strip is heated, for Measuring processes on the belt and for building up magnetic fields, which are used for Initiation of restraining forces are used.
  • Power supplies become current-conducting in the carriage-like roller blocks Materials introduced.
  • the current can then be switched on specifically, when the roller blocks pass through the driving area.
  • the energy supply can be switched off at any time.
  • the belt can be pulled through the opposite speed of the chain carriage and the restraining force be regulated by changing the frequency.
  • the all-round carriage chain system has the task of carrying the band and a fixed band gap to ensure the measuring heads or solenoids.
  • the dwell time for the testing process can be set by defining the contact distance because in this area the metal belt and the car chain system have the same speed.
  • the application offers itself on for strip thickness measurements, tension measurements in the strip, surface scans and other test systems.
  • the supply of the currents can be done either from the inside or from the side.
  • the feed and Switching off takes place after the chain carriage reaches the parallel route has or before it leaves the parallel route.
  • the arrangement shown has the great advantage that the individual Tape strips without deflection roller tangentially fed to the take-up reel 1, 2 become.
  • the retreats built up in the brake scaffold 5, 6 are without loss of deflection and without relative movements to the point of impact brought. This creates ideal conditions for a uniform specific strip tension distribution sharpened.

  • the brake scaffold 20 hangs in the control frame 21 by means of leaf springs 24.
  • the belt tension can be changed by means of load cells 23 without being distorted by deflections with a very low hysteresis and very high repeatability be measured.
  • the brake and train frame 20 exists from the stand, oppositely arranged revolving rollers 5 and 6, which are installed in guides 18 of the stand 20 and of which the upper revolving roller 5 by means of piston rods 18 acted upon by a cylinder is turned against the lower roller 6.
  • the chains 11 and 11a are composed of a large number of coupled, cart-like roller blocks that span the entire Extend the width of a band 4 arriving in the direction of arrow 25 and with at least two-sided support wheels 26 and side guide rollers 27 unroll on a running track or lie on it sideways. The career is led to a driving area in which the opposite Roll blocks 11 grasp the tape 4 on both sides and clamp between them.
  • the coating supports 13 have an elastic coating 12 Mistake.
  • the coating width corresponds to the chain pitch T and extends within the axes of the support wheels 26 of two adjacent, i.e. consecutive blocks. The axes form simultaneously a defined pivot point.
  • the coating 12 is free 30 designed so that a particularly elastic adjustment on the inlet and outlet side the crushed coating becomes possible.
