Description

Technical field

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.

State of the art

From EP-A-0088347 and EP-A-0195096 a brake scaffold for metal or sheet metal strips known with which the braking of metal strips required traction or braking force without damaging effects on the surface of the split or non-split tape can be applied.

The application of the eddy current effect for braking electric Conductive metal tape is described in DE-AS 1 288 865. This Embodiment has been used in practice. The essential The disadvantage is that the desired function usable only when a belt speed of approx. 50 m / min is reached. The belt tension control could only be done by changing the distance respectively. The result was unsatisfactory, since too short distance a contact with the magnet relative movements caused.

Another eddy current brake is described in the published patent application DE 195 24 289 A1 described. The main difference is that the permanent magnets are moved on a circular path. For the Only a magnetic track is available for the retention effect. Also poses the parallelism of the permanent magnets only for a fraction of the period a, which makes the retention effect uneven and essential is built reduced. For sufficient specific tape tension to be able to apply, the speeds of the brake rollers should not in more manageable orders of magnitude. Also ask great drive power with a very unfavorable efficiency on.

Presentation of the invention

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 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 µ-value driving forces generated.

As a further possibility, there are two rotating rollers with permanent magnets or be equipped with electromagnets and through the applied magnetic poles a parallel, linear, magnetic Wanderfeld is built up in the electrically conductive strip material acts as a linear, circulating eddy current brake.

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.

If 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.

An optimal mode of operation is achieved if the mechanical linear drive is operated by an electric linear drive. This Embodiment loads the car chain system only in the linear driving area and is therefore especially for large forces and large ones Speeds make sense.

If the brake scaffold is placed on a control frame at passline height, so is an extremely precise control of the tape in relation to the Belt center or belt edge possible, because this measure the Tilting moment is "constructed". This causes train fluctuations avoided by vibrations. For roll and stretch-bend straightening processes this is an important aspect.

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.

For high demands, for example for very sensitive surfaces Strips, such as copper or aluminum strip, are made by the invention 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. This way you can be relative absorb large pressing forces that are necessary to large Tension or retention forces without relative movement between the belt and to ensure the rotating, carriage-like roller blocks. 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. For the 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. Apart from better efficiency compared to conventional gas or Oil-fired annealing furnace systems is a great advantage of this measure in that the energy supply can be switched off at any time. at By using the eddy current method, the belt can be pulled through the opposite speed of the chain carriage and the restraining force be regulated by changing the frequency.

Become the coating carrier of the trolley chain system with measuring probes equipped, so the rotating table ideal conditions for evaluation created. 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.

Using the same system, single magnets or solenoids, which go over the entire segment area, supplied with voltage become. The tape is applied to the magnetic attraction Chain car pulled. Depending on these forces and that Belt tension can be applied via the chain carriage system become. This is also possible using permanent magnets. This training lends itself to magnetizable metal strips.

Ways of Carrying Out the Invention

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 belt tension distribution created. The tangential inlet is constantly adjusted. The number 1 shows the winding mandrel of the winding reel, 2 the wound coil, 3 the third separation for the Tape strips, 4 the metal tape, 5 the upper roller, 6 the lower one Circulating roll, 7 the second separation and 8 the first separation to feed the metal strip from the loop 9 to the brake stand at right angles. 10 is the splitting shear.

The peculiarity of this solution according to FIG. 2 is that the mechanical Linear drive moved by an electric linear drive 19 becomes. With this solution it is possible to pull large straps on the shortest Initiate ways into the metal band. During the redirections only the forces from centrifugal forces and hinge movements fall for the carriage chain on. The carriage chain 11 can be made simpler. The entire drive chain consisting of the shaft with the Sprockets, cardan shaft, gearbox, clutch and electric motor. It become much higher speeds with high speed Belt tension easily mastered. Number 12 shows the elastic segment coating, 13 the coating carrier, 14 the running rail.

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. The pinch height the coating should be as low as possible to avoid the Keep flexing work as low as possible. At the same time, the coating get a very high elasticity in the direction of tape tension about the different inclination of the coating To enable belt speeds for the individual slit strips, as shown in Fig. 5. This contradiction in terms of function was achieved by the inventive design that by means of the support plates 31 and 32 about the form factor the crushing height of the task can be adjusted, but the inclination of the coating is only marginally restricted. Figure 4 shows the position the coating with low tape tension, Fig. 5 with high tape tension.

If the coating carrier 13 with permanent magnets 33 or Equipped solenoids 34, which build up eddy current fields, so electrically conductive strips, in particular strips made of aluminum, Copper, as well as their alloys, are used to initiate strip tension become. The carriage chain is usually against the belt running direction emotional. The length of the contact distance (effective distance) can Adjusted if necessary.

6 is for metal strips with the highest Surface requirements of great interest as there is no contact with the Braking system is present. The distance between the permanent magnets 33 or coils 34 can be kept constant in that the supports of the idler rollers are set by the elastic blocks 35 become. The metal band 4 floats due to the attractive forces between the permanent magnets 33 or the coils 34. The protective belt 36 is also shown. Are the cylinders 18 by spindle drives the distance can be adjusted and the machine hereby receives an additional control element.

If the coating carrier 13 with permanent magnets 33 or Equipped with magnetic coils 34, which build up magnetic fields, so magnetizable Metal tapes, used to initiate tape pulls become. The carriage chain is moved in the direction of the belt. The The length of the contact path can be adjusted as required.

This form of training is for metal strips with the highest surface demands of great interest as contact to the Braking system is present.
