Definitions

  • the invention relates to a winding device for webs with two winders, which are equipped in pairs on both sides of the web with a winding core acting on the winding core and together with an upstream deflecting element is mounted axially parallel on a rotatable console and the winder exchange its position by pivoting the console by 180 ° can and alternately in a winding position a started winding finished winding and in a waiting position a new winding can be operated, and with a separator mounted independently of the console, which acts on a web section between the two winders, while the web tensioned between the winding holders of the the waiting winder is passed through to the winder in the winding position, and in which the material web partially wraps around the deflecting element at every filling level of the resulting winder and only after this wrapping is still in contact with the resulting wrap.
  • Such a winding device is known from US-A-2 272 940, in which the winding core consists of two parts, one. Leave a slot between them that extends across the entire width of the web. The web for a new winding core is inserted into this slot by opening and then closing the winding core. This is cumbersome and not suitable for fast, automatic alternating operation.
  • a winding device for winding flat windings on board-shaped winding cores.
  • the winding cores are inserted in grooves between two opposing winding holders and then the beginning of the web is clamped to the winding core and the winding process can begin.
  • Such a device is not suitable for automatic alternating operation.
  • Webs are processed with winding devices, which tend to form folds during winding. This is particularly the case when such webs of material are wound up on small winding cores.
  • the object of the invention is to design a device of the type mentioned at the outset so that automatic alternating operation is possible and that webs which tend to form folds can also be wound wrinkle-free on board-shaped winding cores. Forced breaks at the start of a new reel should be as short as possible.
  • the invention is characterized in that the winding holder has a rotatable and longitudinally displaceable to the winder axis within a winder housing mounted clamping head, in which one or more collets are expandable and closable, the clamping jaws of which project from a face of the clamping head facing the web and through one inside the Clamping head-mounted, spring-loaded lever gear with the tensioning head advanced to attach the respective reel holder is closed and locked and opened when the tensioning head is retracted to place the reel holder, and that the reel holders are displaced axially from a remote position next to the web, which they assume while the associated winder is in the waiting position, can be adjusted into a position in which the Wicksin occupies, in which the collets grip and clamp the edge of the material web together with an inserted winding core.
  • the web is clamped at its edges under the tension under which it is kept ready, the ends of the winding core being clamped at the same time. This maintains the tension, even in the individual layers of a doubled or multi-layered sheet, so that, as experience has shown, undesirable wrinkling can be avoided.
  • 1 denotes the machine frame, on which a bracket shaft 5, which is rotatably mounted about the bracket axis 4, is mounted in two pivot bearings 2 and 3.
  • Two brackets 6, 7 are mounted on the bracket shaft 5 so as to be longitudinally displaceable but torsionally rigid.
  • the brackets can be moved on the bracket shaft 5 by rotating a handwheel which is mounted on the associated bracket and drives a pinion which engages in a rack which is fastened to the bracket shaft 5.
  • the handwheel 38 for the console 7 is only shown in FIG.
  • the rack is designated 39.
  • the rack also serves as a rotation lock for the console on the console shaft 5.
  • winder holders 8, 9, 10, 11 are mounted on the brackets, of which the winder holders 8, 10 are arranged coaxially with the winder axis 12 and form the winder 13, while the winder holders 9, 11 are arranged coaxially with the winder axis 14 and the winder 15 form.
  • the winding holder 8, 9, 10, 11 are arranged in mutually facing sides of the brackets 6, 7 in pairs facing each other.
  • the fabric web 16 shown in FIGS. 5a to 5c extends between the winding holders.
  • the fabric web 16 can be simple, as shown in FIG. 4a; twice, ie doubled, as shown in Figure 4b; doubled, ie fourfold, as shown in Figure 4d; placed three times, as shown in Figure 4c, or otherwise placed several times.
  • the longitudinal fold along the longitudinal folds 18 to 23 serves to wind a wider cloth web according to FIGS. 4b, c and d onto a winder 25 which is less wide according to the double arrow 24 in order to facilitate storage.
  • the web of fabric 16 passes from the upstream machine 17 - apart from the longitudinal folds - into the winding device without any creases and is to be wound up by the winding device to form windings corresponding to the winding 25 and the formation of additional new folds, poses and the like is to be avoided.
  • the individual winding holders are assigned drive motors 40, 41, 42, 43, which, as can be seen in FIGS. 2 and 3, are mounted on the relevant console 6 and 7 in addition to the associated winding holders. Each winding holder is thus driven directly by the drive motor assigned to it. With these drive motors, clamping heads 44, 45, 46, 47 of the individual winding holders are driven in rotation about the respective winding axis 12, 14 during winding. The clamping heads 44, 45, 46, 47 are rotatably and longitudinally displaceable in the associated winding holder.
  • Hydraulic cylinders 50, 51, 52, 53 assigned to the individual reel holders are used for longitudinal displacement, which are each mounted axially parallel to the corresponding reel holder on the relevant console 6 or 7 and each have a push bar, for example push bar 56, on one Actuate push rod 57 of the relevant winding holder 10.
  • the winding holders 8, 9, 10, 11 are of identical design and are arranged mirror-symmetrically to the plane of symmetry 58, which is perpendicular to the plane of the drawing in FIG. 1.
  • the winder holders of a winder for example the winder holders 9, 11 of the winder, for example the winder holders 9, 11 of the winder 15, are operated together and synchronously. It is not absolutely necessary but expedient to provide a device for synchronizing the rotary movement.
  • a coupling shaft 60 which is rotatably mounted on both brackets axially parallel to the winding axis 14, is used for the winding holders 9, 11 and is connected in a torsionally rigid manner to the two winding holders 9, 11.
  • the corresponding coupling shaft for the winding holder 8, 10 is designated 61.
  • the drive gear 35 of the drive motor 41 meshes with a drive gear 36 of the winding holder 10.
  • the drive gear 35 also meshes with a deflection gear 37 which is torsionally rigid but axially displaceably on the coupling shaft 61.
  • the opposite winding holder 8 of the same winder 15 is connected to the rotary movement of the coupling shaft 61, and thus also to that of the winding holder 10, synchronized by the deflection gear 114, which is torsionally rigid and axially displaceable on the coupling shaft 61 and meshes with the drive gear 115 of the drive motor 43 .
  • the coupling shafts 60, 61 extend over the maximum distance between the two brackets 6, 7 and are axially displaceably mounted in them so as not to impede the longitudinal displacement of the brackets along the bracket shaft 5.
  • Deflection tubes 62, 63 are arranged coaxially to the coupling shafts 60, 61.
  • Each of these deflecting tubes for example the deflecting tube 63, compare FIG. 14, consists of two tube sections 64, 65 which are telescopically placed one above the other in pairs and of which one tube section 64 is attached to one bracket 7 and the other tube section 65 to the other bracket 6 .
  • the deflection tube 63 formed by the tube sections can thus be telescopically pulled apart and plugged together and thus follows the distance between the brackets 6, 7 in its length the middle of the fabric web 16 starting in the conveying direction according to arrow 70 obliquely to the side extend.
  • the ribs each extend only over those outer parts of the tube sections 64, 65 which do not overlap when telescopically pushed together.
  • the ribs 67 are, based on the axial direction of the associated deflection axis 71, narrower than 1/10 of the width according to double arrow 74 of the spaces 75, 76 to the adjacent ribs according to double arrow 73.
  • the ribs 67 are formed by two spirals 77, 78.
  • deflection rail that has a wrapping surface that is curved in the wrapping direction of the fabric web and that extends over the greatest wrapping angle that occurs.
  • the ribs are advantageously provided, but can also be omitted.
  • the deflection tube 63 is not rotatable. In a modification, however, the deflection tube 63 can be rotatably mounted about the deflection axis 71, it can be driven to rotate about this axis and can be coupled to the drive of the associated winder for this purpose.
  • the deflection tube 63 belongs to the winder 13.
  • the deflection tube 62 which is designed correspondingly to the deflection tube 63, belongs to the winder 15.
  • a deflecting tube 62, 63 or a deflecting element is assigned to each of the winders and is arranged directly upwards of this associated winder.
  • the deflection element is arranged in such a way that when the winding is filled to the maximum, there is at least one tolerance distance 174 between the deflection element and the winding (see FIG. 5a), so that the filled winding can rotate smoothly past the deflection element.
  • the deflecting element is arranged so far offset that when the winding is filled, the taut sheet of fabric wraps around the deflecting element with a wrap angle 79 of at least 10 °, so that the sheet of fabric 16 does not undesirably lift off and flutter from the deflecting element even when the winding is full. If the winding is less filled, as can be seen in FIG. 5a, a larger wrap angle 79 then results.
  • the fabric web 16 is only in contact with the resulting wrap. Following the deflecting element, the fabric web reaches the winding directly. It is wound up freely there and is not under the pressure load of a pressure roller, which loads from the outside on the winding being formed. Such a pressure roller would lead to undesirable wrinkling.
  • a board magazine 80 is arranged, which is attached to the machine frame 1.
  • the board magazine is filled with a pile of boards 81 serving as winding cores, of which the bottom board 82 is released in the direction of the arrow 84 with the aid of a distributor 83 assigned to the board magazine 80, whereupon the other boards move downward in the direction of the arrow 85.
  • the board magazine is adaptable to boards of different lengths according to the width of the fabric sheet 16 being processed.
  • the allocator 83 places the dispensed board on the then idle cloth web 16 between the two winder holders 9, 11 of the winder 15 which is in the waiting position.
  • the board magazine 80 can be adapted to different widths of the cloth web.
  • the two magazine cheeks 86, 87 are fastened to cheek supports 31, 32 which can be displaced transversely.
  • the cheek beam 31 is mounted on a slide rod 91 and on a parallel threaded spindle 90 in the direction of the console axis 4.
  • Threaded spindle 90 and slide rod 91 are mounted in end shields 28, 92 on the machine frame 1.
  • the cheek carrier 32 is mounted accordingly.
  • the associated hand crank is designated 27, the rod 89 and the threaded spindle 88.
  • a separating device, generally designated 180, is arranged on a cross member 184 below the winders 13, 15.
  • the cross member 184 is mounted on both sides of a hydraulic lifting cylinder 185, 186 adjustable in height on the machine frame 1.
  • Knife disks 187 which can be driven to rotate and are distributed over the width of the fabric web are arranged on the cross member 184, the circumference of which is a polygon and is designed as a cutting edge. With their cutting edges, the knife disks 187 form a horizontal, combined cutting edge which extends over the entire width of the fabric web, as indicated by the dash-dotted line 188 in FIG. 1. In the lower rest position shown in FIGS. 1 and 5, the separating device 180 is ineffective.
  • the separating device 180 is arranged in such a way that, as can be seen particularly well from FIG. 5a, it is effective immediately downstream of the winder 15 which is in the waiting position.
  • a driver sleeve 113 in ball bearings 103, 104 and a rotary sliding bearing 112 in the ball bearing 102 are rotatably but not longitudinally displaceable.
  • the bearing tube 107 is mounted in a longitudinally displaceable manner in the rotary sliding bearing 112 and in the driving sleeve 113.

  • the push rod 154 is guided against rotation in a slot 165 of the end face 140.
  • the front tapered end of the push rod 57 is rotatably coupled in ball bearings 190, 191 to prevent longitudinal displacement.

If this has happened, then the separating device 180 returns to its initial position and the motor 182 can be switched off. It can also continue to run empty until the next cut.
  • the winder 15 begins its rotational movement in the direction of the arrow 200 and at the same time the cloth web feed in the machine 17 is switched on and the winder 15 begins to wind a new roll on the board 82.
  • the console shaft 5 begins a pivoting movement by 180 ° in the direction of arrow 181, see FIG. 5, at the end of which the two winders 13 and 15 have exchanged their positions.
  • the winders rotate about the winder axes in the same direction of rotation according to arrow 200 and arrow 175 as the brackets 6, 7 rotate about the console axis according to arrow 181.
  • the same direction of rotation of the brackets on the one hand and the winder on the other hand favors the crease-free winding during the turning process of the brackets.
  • the winder 13 makes a few slow revolutions in the direction of the arrow 175 and in the process completely winds up the free cloth web end 202 which has resulted from the separation process. Once this has been done, the winder 13 releases the filled roll 25 and lets it fall off by retracting the clamping heads with the swords into their offset position according to FIG. 6a.
  • the two winders 13, 15 have exchanged their position according to FIG. 5, the winder 15 winds the started winding completely in the winding position that the winder 13 holds in FIG. 5, and the winder 13 stands in the waiting position, which the winder 15 holds in FIG. 5.
  • FIGS. 10 and 11 A correspondingly modified exemplary embodiment is explained with reference to FIGS. 10 and 11.
  • the sword corresponding to the sword 155 is missing and the collet 270 is only in one piece and has two clamping brackets 271, 272 with circularly curved clamping jaws 273, the curvature of which is adapted to a tube piece 274 serving as a winding core.
  • a centrally arranged winding core 280 is provided, which instead of the push rod 154 has a rod 282, on the free end of which a round clamping block 281 is attached.
  • the tensioning block 281 moves into the interior of the tube piece 274 when the winding core holder 280 is extended.
  • the rod 282 is mounted on the coupling element 283 corresponding to the coupling element 121, like the push rod 154.
  • a clamping mandrel 276 is fastened coaxially to the winder axis 275 and also fits into the tube piece 274.
  • the tensioning block 281 strikes the mandrel 276 and, like the crossbar 178, thereby takes the tensioning head back into the rotationally secured position.
  • the sword 155 and the swords of the other winding holders corresponding to this can be omitted if the board is a sufficiently rigid winding core.
  • Parts of the clamping head of a corresponding exemplary embodiment are shown in FIGS. 12 and 13.
  • the sword is missing.
  • a circular bushing 240 is provided on both sides, through which a mandrel 242, which is longitudinally displaceable in the clamping head 241 and parallel to the winder axis 14, projects.
  • the mandrel 242 is under the load of a compression spring 243 and can be pressed back into the interior of the clamping head by overcoming the restoring force of this compression spring 243.
  • a board that has holes at corresponding points on its end face is additionally held by the mandrel 242 and the opposite, invisible mandrel, which then engage in these blind holes when the clamping head is attached. If there are no blind holes, the mandrel 242 is ineffective and is pushed back by the board into the clamping head against the force of the spring 243.
  • the collet 244 with its return spring 245 and its tolerance spring 246 is otherwise designed in exactly the same way as the collet 130 from FIG. 6 and is also mounted in the clamping head 242 just like this.
  • a driver 291 is mounted on the front end of the coupling piece 290 corresponding to the coupling element 121 and is fastened to the clamping head 241.
  • the longitudinal displacement of the driver 291 with respect to the coupling element 290 is limited by a bolt corresponding to the bolt 163 with an associated longitudinal groove.
  • deflection tubes 62, 63 can also be used in devices in which the brackets 6, 7 cannot be adjusted in their spacing.
  • This deflection tube is fastened between the fixed brackets 301, 302 and is wrapped in the cloth web 303.
  • the deflection tube 300 has an increasingly larger diameter toward the tube center 304, which corresponds to the center of the fabric web.
  • the two pipe halves thus created are coated with a spiral-shaped pee 305, 306.
  • the spiral windings extend mirror-symmetrically to one another, with an incline such that the spiral paths are inclined outwards in the direction of the cloth web advance according to arrow 307 and act on the cloth web stretching outwards.
