Definitions
- the invention relates to a device for straightening warpage in a textile web, according to the preamble of claim 1.
- each driven roller part is assigned an external control gear, the drive shaft of which extends axially into the straightening roller and is connected there in a rotationally fixed manner to the corresponding roller part, the drive shafts partly having to be designed as hollow shafts.
- a number of pressure rollers which are adjustable in the direction of the width of the textile web, are provided, which in turn are driven by a switchable electric motor and then pressed against the correspondingly rotatable roller parts in order to drive the latter by friction.
- This type of drive for the individual roller parts requires a lot of space in the circumferential area of the straightening roller, is difficult to handle and, moreover, is unreliable when it comes to achieving precise drive speeds for the individual roller parts.
- the invention is therefore based on the object to provide a device of the type required in the preamble of claim 1, which can also be reliably maintained at the speed for the individual roller parts of the or each straightening roller by a relatively simple and space-saving design and arrangement of the roller part drives then distinguished if the straightening roller has a relatively large number of axially adjacent roller parts.
- the overall drive for each roller part of a straightening roller is, as it were, divided into a gear transmission arranged within the associated roller part and an external drive which is provided outside the actual straightening roller and on the end face thereof and which can be varied in terms of its speed, this external drive and the inner gear transmission being provided by one Part of this straightening roller axially penetrating and corresponding in length adapted drive shaft are connected.
- the gear mechanism can be accommodated in a space-saving manner within an otherwise unused part of the straightening roller. Because of this gear mechanism provided within the associated roller part, the external drive provided in the area of the outside of the corresponding roller end can be kept relatively small, so that this contributes to a further saving of space.
- a straightening roll designed in this way can perform practically all occurring straightening functions reliably and precisely, i.e. it can compensate for diagonal warping, central warping, unilateral warping and even S-shaped warping of a running web.
- each gear transmission can be a spur gear, which has a drive pinion arranged on the inner end of the drive shaft and a toothed engagement, which is in meshing engagement with it and is provided on the inner circumference of the associated roller part Contains ring gear.
- roller shell of which is sufficiently large in the axial direction Number is divided separately in each case with variable speed drivable roller parts, ie in the case of FIG. 1 the roller jacket of the leveling roller 1 is - for the sake of simplicity - only divided into four roller parts 1a, 1b, 1c and 1d. All roller parts 1a to 1d are designed in the form of hollow cylinders.
- a separate gear transmission is arranged, which is preferably designed in the form of a spur gear, each spur gear essentially by a drive pinion 2 and a toothed engagement with it, provided on the inner circumference of the associated roller part 1a to 1d, internally toothed ring gear 3 is formed.
- Each gear transmission 2, 3 is assigned a separate drive shaft 4a, 4b, 4c and 4d, which carries the associated drive pinion 2 in a rotationally fixed manner on its innermost end 4a 'to 4d' within the associated roller part 1a to 1d.
- Each drive shaft 4a to 4d extends from the associated roller part 1a to 1d through an end face 1L or 1R of the end roller 1 to the outside.
- the outer drive shaft ends 4a ⁇ , 4b ⁇ , 4c ⁇ and 4d ⁇ are each connected to a separate external drive 5a, 5b, 5c and 5d. All external drives 5a to 5d are designed so that their speed is infinitely variable, as is known per se.
- the external drives 5a to 5d for the individual roller parts 1a to 1d are assigned in part to one roller end 1L and in part to the opposite second roller end 1R.
- the illustrated example are at the left end of the roll 1L three external drives are provided, while only one external drive 5d is arranged at the right end of the roll end 1R.
- the external drives for the individual roller parts can be allocated to the two ends of the rollers evenly divided, the drive shafts 4a to 4d then being separated from the associated gear transmission 2, 3 for each can extend closest roller end.
- all drive shafts passing through the same roller part will preferably be arranged at approximately the same circumferential distance from one another about the longitudinal axis of the roller LA and at approximately the same radial distance from it, as can also be seen from the cross-sectional illustration in FIG.
- these can be formed by a motor, preferably a controllable geared motor with an associated belt or chain drive.
- a direct coupling of the regulated geared motor to the associated drive shafts 4a to 4d can also be provided.
- the individual drivable roller parts 1a to 1d are rotatably supported on a stationary (non-rotatable) support body 6 which passes through the straightening roller 1 in the axial direction.
- This support body 6 can be arranged at its o free axial ends fixedly in a roller frame or the like, not illustrated in any more detail, as is known per se.
- the support body is essentially formed by a sufficiently thick-walled support tube 6 of relatively large diameter.
- this support tube 6 now carries at least one bearing plate 7 attached to it.
- Each of these bearing plates 7 is formed by two parts, namely a flange-like outer ring part 7a and an approximately circular inner plate 7b arranged approximately in the same plane.
- the associated roller part 1a to 1d is freely rotatably mounted on the outer circumference of each bearing plate 7 or from its outer ring part 7a.
- a roller bearing 8 is arranged between the outer circumference of each end shield outer ring part 7a and the inner circumference of the associated roller part.
- the support tube 6 is designed with a sufficiently large diameter so that the drive shafts 4a to 4d can run within this support tube in the manner explained above.
- the drive shafts 4a to 4d - as can be seen in particular in FIG. 2 - are rotatably supported in the vicinity of the inner circumference of this support tube 6.
- Each drive shaft 4a to 4d can on the one hand in the end plate 7L or 1R arranged at the associated end face of the roll and on the other hand in the area of its inner end 4a 'to 4d' also in an inside of the associated one
- the roller part of the bearing plate 7 carried by the bearing plate 7 can be rotatably mounted.
- through holes 9 are provided in the inner plates 7b of the end shields 7 for each drive shaft 4a to 4d, position and size of which are adapted, support bearings being provided in the corresponding through bores 9 at least for the drive shafts ending in the associated roller part 1a to 1d.
- These support bearings can be formed, for example, by a roller bearing 10 arranged essentially in the associated through bore 9.
- the drive shafts 4a to 4d are arranged in the vicinity of the inner circumference of the support tube 6 and parallel to it, the drive pinions 2 arranged on their inner ends 4a 'to 4d' having a correspondingly large circumferential section by a in the
- the window-like opening 11 provided in the support tube wall extends radially outwards so far that they can be held in reliable tooth engagement with the internally toothed ring gear 3 of the associated roller part 1a to 1d.
- Fig. 3 shows a partial longitudinal section of a second example of the execution option of the straightening roller.
- a first difference of this second example (Fig. 3) of the straightening roller 1 'compared to the previously described (Fig. 1 and 2) can be seen first in the formation of the continuous, fixed support body 12, which is also formed by a sufficiently thick-walled support tube 12 can be, however - compared to the first example - has a significantly smaller diameter, but is also arranged coaxially to the longitudinal axis of the roll.
- a cross-sectionally annular space (annular space) 13 is thus formed between the fixed support tube 12 and the inner circumference of the roller parts 1'a, 1'b, 1'c, in which case the drive shafts, e.g. 4'c, run parallel to the support tube 12.
- End shields 14 are in turn provided with through openings 9 'on the outer circumferential side, through which the various drive shafts can pass freely or can be supported and supported in a rotatable manner by means of roller bearings 10'.
- the end shields 14 of this embodiment can be made so long in the axial direction that adjacent driven roller parts, for example 1'a and 1'c, can be rotatably supported on their outer circumference at the same time.
- roller bearings 8 '- similar to the first example - are arranged between the outer circumference of each end shield 14 and the inner circumferential sides of the driven, mutually adjacent roller parts 1'a and 1'c.
- each drivable roller part 1'a, 1'c is also carried out in the same manner as described above with reference to FIGS. 1 and 2, i.e. with the help of a spur gear from drive pinion 2 '(on the associated drive shaft 4'c) and provided on the inner circumferential side of the associated roller part (1'c), internally toothed ring gear 3'.
- FIG. 3 Another peculiarity of this second embodiment (Fig. 3) can also be seen in the fact that between two adjacent driven roller parts, e.g. 1'a and 1'c, a relatively short roller intermediate part 1'b is arranged in the axial direction, which is mounted on an associated bearing plate 14 carried by the fixed support tube 12 independently of the driven roller parts so that it can rotate freely.
- the end shield 14 can be dimensioned so large in the axial direction that between its outer circumference and the inner circumferences of the adjacent driven roller parts 1'a and 1'c and the roller intermediate part 1'b provided between them, one roller bearing 8 'for each rotatable support ensures.
- roller intermediate part 1'b between two adjacent driven roller parts avoids that sharp-edged distortions of the wefts to be straightened of the textile web occur at the parting line between two driven roller parts.
- Such roller intermediate part 1'b can be kept very short compared to the driven roller parts; in practical exemplary embodiments, the axial length of this roller intermediate part with a length of approximately 50 mm can already be sufficient.
- the same axial length can be provided for all roller parts of the straightening roller in all embodiments, or at least some or all of the roller parts of this straightening roller can have a different length. These embodiments will generally depend on the particular application of the straightening roller or the straightening device containing the straightening roller.
- the straightening device containing this straightening roller designed according to the invention can be used extremely versatile in a separate installation or also in direct association with a textile web treatment machine. It should also be mentioned here that the infinitely variable speed regulation of the individual drives of each roller part can be carried out independently of one another and electronically, manual speed adjustment with visual detection of textile web distortions also being possible. Furthermore, measuring and detection devices known from practice can be used for the automatic control, in which case at least one measuring point is then required for each roller part.
- the entire straightening device in the inlet part 21 of a known, preferably as a stenter Dryer and / or fixing machine running textile web treatment machine is integrated.
- a deflection and support roller 23 In the inlet part 21 of this treatment machine - viewed in the transport direction (arrow 22) of the textile web T to be treated - one after the other or one above the other, a deflection and support roller 23, a feed roller 24, a straightening roller 25 in one of the above-described embodiments with a plurality of roller parts and also one Spreader roller 26, a deflection roller 27, an optical sensor device 28 for determining the alignment state of the textile web T, a deflection roller 29, a further spreader roller 30 and a simple feed roller 31 are provided, from which the textile web T can be supplied with tensioning chains or the like.
- a special feature here is also thought of keeping the straightening roller 25, which is divided into individually drivable roller parts, diagonally adjustable, as indicated in FIG. 4 and symbolized by a double arrow 32.
- the straightening roller 25 can thus be adjusted in its entirety, so that in addition to the straightening work which can be achieved by the individual roller parts, particularly large diagonal distortions of weft threads can be aligned.
- Fig. 5 shows a modification of the installation option previously described with reference to Fig. 4 in the inlet part 21 'of a similar textile web treatment machine.
- a straightening roller 34 designed according to the invention (roughly corresponding to the example according to FIGS. 1 and 2 ), a first diagonal straightening roller 35, a first spreader roller 36, a second diagonal straightening roller 37 and - similarly to the previous example (FIG.
- the straightening device according to the invention into the outlet part 41 of a textile web treatment machine designed in particular as a stenter dryer and / or fixing machine, regardless of the design of the inlet part of a textile web treatment machine, as shown in FIG 6 is indicated schematically.
- This straightening device is arranged behind a pull-out roller 42 of this treatment machine. Underneath or behind this pull-out roller 42, viewed in the direction of travel (arrow 43) of the textile material T, a deflection roller 44, an inventive, divided straightening roller 45 (approximately corresponding to the above-described explanations according to FIGS.
- the position of the weft threads can be determined with the help of the optical sensor device.
- These optical sensor devices are expediently - as shown and explained with reference to FIGS. 4 to 6 - arranged in the running direction of the textile web T behind the respective straightening roller or the last straightening roller. Deviations from the desired undistorted weft position are used by automatic control of the diagonal straightening rollers and the individual drives for the roller parts of the straightening roller to correct these advantages.
- two or more such rollers or straightening rollers divided into individually driven roller parts are provided in the inlet part of a textile web treatment machine or a separately erectable straightening device, then the total straightening work to be carried out on a warped textile web is divided into two or more such divided straightening rollers, whereby a particularly gentle, to a certain extent, multi-stage alignment of the detected textile web distortions can be achieved, which is particularly advantageous for larger textile web distortions.
- control signals derived from the measuring or sensor devices and control devices can be determined by the number of available divided straightening rollers are divided, each sub-straightening roller then being supplied with a partial actuating signal corresponding to the manipulated variable to be regulated.
