Definitions
- the invention relates to a method for rolling or winding of tape with Unequal thickness over the bandwidth, in which by means of a measuring roller the Tension across the belt in one of rollers, reels, control, or pulleys limited length section of the belt is measured and takes the priority of the German patent application 199 45 202.4 on, on the content is referred to.
- Such broadband often becomes longitudinally narrower bands divided.
- These longitudinally divided bands slit strips
- These longitudinally divided bands then have at least partially a wedge-shaped cross-section, in which an edge region thicker than that other, opposite edge area is.
- Such a wedge-shaped cross section leads to difficulties in the further processing of the slit strip. This applies whenever the slit strip rolled, wound on reels or over Rollers, such as pulleys, is performed.
- the stabilizing rollers should depend on the distribution of tensile stresses on the Width of the band to be adjusted. For this purpose, the tensile stress distribution measured. Therefore, in the known device, the stabilizing rollers stored on bearing blocks, where force sensors for Determining the present in the band traction asymmetry are arranged.
- the invention is based on the object, a method and / or a device with which it is possible to obtain more accurate readings.
- the distortions when running the band caused interference voltages in the band are by means of a Shielding device kept away from the measuring roller.
- Shielding device ensures that only those tensile stresses in the area of the measuring roller occur in the band, resulting from the different length of the band about its width.
- the above-mentioned interference voltages can be Although not unavoidable with tape of uneven thickness, but with the sealing device away from the point of the tape, where the measuring roller the Tensile stress distribution in the belt measures.
- the invention also relates to a device for rolling or Wrapping tape of unequal thickness across the tape, which is a measuring roll for measuring the stresses in one of rolls, reels, control, guiding or pulleys limited length portion of the belt has.
- This device is characterized according to the invention in that between the measuring roller and an interference voltage in the band causing aggregate (Roller, reel, control, guide or deflection roller) a Abschottvortechnisch is arranged to receive the interference voltages.
- the Abschottvortechnisch is arranged between the measuring roller and that point from which the interference voltages out.
- it may be necessary second Abschottvorides use when from a second side Interference voltages to the measuring roller out can be effective.
- the measuring roller when using the Abschottsysteme actually only those voltages over the bandwidth corresponding to the length distribution of the tape and from which correct values for controlling, regulating and measuring can be derived.
- the Abschottvorraum one, preferably several rollers, which have a non-slip surface and a sufficiently large wrap angle to be in close contact with keep the tape. This close contact with the band causes an alignment effect in the belt, because the interference voltages from the belt to the rollers and their storage be transmitted and derived.
- rollers of the Abschottvoriques while adjustable, but are stored stationary during operation.
- the adjustability of Rolling allows a perfect setting of the same, especially for Ensuring the largest possible wrap angle and thus one sufficient Abschottrial.
- a solid stationary storage of roles During operation ensures a reliable derivation of the interference voltages.
- Two rollers 1 and 2 form between them a nip 3, through which a Band 4 passed, rolled and thereby reduced in thickness.
- a reel 5 is arranged, on which the Volume 4 is wound.
- a measuring roller 6 supports the band 4 from below. Not shown sensors in the measuring roller measure the forces occurring there, the give a measure of the tension in band 4.
- the band 4 Since the band 4 has a wedge-shaped cross-section, it becomes on the reel wound up on its width differently tight, so that at the thicker tape position sets a higher belt tension. This leads to the belt 4 between reel 5 and measuring roller 6 is deflected to the side. This is in Fig. 2 for the purpose of a clearer representation of the consequences of the deflection a bit exaggerated.
- the unbalanced belt tension leads that the tape is bent and not with its side edges perpendicular to the reel 5 meets, that is, no longer at an angle of 90 ° to the axis of rotation 7 of the reel 5.
- This move during winding of the wedge-shaped cross-section band 4 the casserole points of the Bandes on the reel 5, and there is an asymmetrical waist geometry.
- Fig. 2 Since the band 4 has a wedge-shaped cross-section, it becomes on the reel wound up on its width differently tight, so that at the thicker tape position sets a higher belt tension. This leads to the belt 4 between reel 5 and measuring roller
- the casserole points of the band 4 are marked with arrows 8.
- Measuring roller 6 and reel 5 a completely non-uniform state of stress, at the voltages from the changing band length and the interference voltages superimposed by the unbalanced voltage introduction on Reel and distortions of the running band 4 arise.
- the Measuring roller 6 and its sensors can not between the two types of voltage differ. Consequently, the measured values thus obtained are useless.
- FIG. 3 also shows a device for rolling a strip 4, which is wound by a reel 5. It is immaterial if the There existing measuring roller 6 is arranged above the belt 4. She works on the same principle as the measuring roller 6 in Figs. 1, 2. Crucial However, that in Fig. 3 between the measuring roller 6 and the reel 5 a Abschottvoriques 9 is arranged. This consists of a roll 10 with a sufficient non-slip surface. The roller 10 should also be arranged so that there is a sufficiently large wrap angle and thus the band 4 has a large-area contact with the roller 10. The role 10 could be around this to reach, also be adjustable. During operation, their location remains however stationary and stable to absorb and dissipate the disturbing voltages, which act from the reel 5 ago against the direction of the tape 4 in the band.
- Fig. 3 is still a plan view of the tape 4, in which the forces are shown as arrows.
- the forces are shown as arrows.
- Far left If one recognizes the unequal forces immediately at the emergence of the band 4 the reel 5 at the point marked 11. In the middle area are represented the forces acting at the point 12 in the band 4.
- On the far right is shown that in the region of the measuring roller 6, for example at the point 13, only the Forces occur, resulting from the length distribution of the strip across the width arise because the noise coming from the reel 5 ago the Abschottvortechnisch 9 do not happen as they are derived.
- FIG. 4 differs from FIG. 3 mainly in that there is a Shielding device 9 is shown, which has two rollers 10. In this way can be an even larger wrap angle in total and thus still achieve more reliable isolation of the interference voltages. Abschottvoriquesen with more than two rolls 10 are quite possible and in some cases also useful and necessary.
