Definitions

  • the invention relates to a rewinder for in the form of parallel strips fed by a longitudinal cutting device web material, with a winding shaft, on which the strips are to be wound, and a parallel to the winding shaft extending comb shaft, are arranged on the sleeves, each having a Separierusion for lateral guidance of Wear stripes.
  • Web material which serves for example for covering profiles or for coating edges of furniture panels and the like, is often provided in the form of a relatively wide endless belt and then divided with a longitudinal cutting device into narrower strips in the respectively required width.
  • the strips are then wound on the winding shaft to closely adjacent coils. If the strips have a relatively large width, so that the winding remains stable even with a larger diameter, it is possible to use two parallel winding shafts, on which the strips are wound in an alternating sequence, so that the winding formed on the same winding shaft in Distance from each other are arranged. Otherwise, all the strips are wound on the same winding shaft so that the successive coils almost touch each other.
  • the comb shaft with its separating discs serves to give the strip in the region of the circumference of the coil lateral guidance, so that the individual coils remain separated from each other.
  • the distances between the separating discs then correspond to the respective strip widths.
  • each sleeve corresponds to the width of the associated strip, so that the sleeves serve as spacers with which the distances between the separating discs are determined. If the slitter is converted to other strip widths, the rewinder must also be adjusted accordingly to be converted. For this purpose, the sleeves are replaced on the comb shaft against a set of sleeves of a different length.
  • the object of the invention is to provide a rewinder that can be easily converted to other strip widths.
  • the sleeves are fixed with at least one extending in the longitudinal direction on the circumference of the comb shaft, radially expandable clamping member in individually adjustable longitudinal positions on the comb shaft.
  • the length of the sleeves is smaller than the smallest expected strip width, so that between the successive sleeves on the comb shaft there are generally certain gaps, which allow to vary the longitudinal positions of the sleeves and thus adapt to the respective strip width, without having to pull off all the sleeves from the comb shaft and replace them with sleeves of different lengths. Not only does this simplify the retrofit process, it also eliminates the need to stock numerous sets of separators-carrying sleeves, each with different lengths.
  • all sleeves and thus all separating discs are set to the desired positions, all sleeves can be fixed in the set position on the comb shaft with the help of the tensioning element.
  • the tension member may be formed by a pneumatically expandable bellows housed in a groove formed in the peripheral surface of the comb shaft.
  • the knives and counter knives are designed as a disc knife, sitting on the respective blade shafts and are also tightened pneumatically in the required positions on the shaft.
  • numerically controlled robots are known with which the plate knives can be positioned automatically.
  • this robot is also used for positioning the Separierusionn. This can for example be done in the form that the robot is moved from a position in the vicinity of the knife shafts in a position near the comb shaft, so that he can position the separating discs in a similar manner as the disc knife.
  • the robot always remains in a position adjacent to the cutter shafts, and it has a position indicator which indicates the desired positions for the separating wheels, so that the separating wheels can then be manually adjusted to these desired positions.
  • the position indicator can be formed, for example, by a laser mounted on the robot.
  • the in Fig. 1 shown rewinder has a winding shaft 10, are to be wound on a plurality of strips of a web material.
  • winding cores 12 for example in the form of paperboard sleeves whose length corresponds to the width of the strips to be wound, are arranged and fixed in suitable positions on the winding shaft 10. With an adhesive tape, one end of each strip is then glued to the peripheral surface of one of the hubs 12. With the aid of a rotary drive, not shown, the winding shaft 10 is rotated, so that the strips are wound into coils 14.
  • a single coil 14 is in Fig. 1 indicated by dash-dotted lines.
  • a comb shaft 16 Parallel to the winding shaft 10, a comb shaft 16 is arranged, which carries a plurality of sleeves 18. Each sleeve 18 carries at one end a relatively thin separating disk 20.
  • the comb shaft 16 is positioned in the directions perpendicular to its longitudinal axis relative to the winding shaft 10 such that the separating disks 20 are combed between the individual strips to be wound on the winding shaft 10.
  • the comb shaft 16 may be automatically adjustable in the directions perpendicular to its longitudinal axis in such a way that it adapts to the gradually increasing diameter of the winding 14, so that the Separierusionn 20 always remain in the region of the outer circumference of the winding.
  • the comb shaft 16 may be passively rotatable, so that the friction between the Separierusionn 20 and the coils 14 is minimized.
  • a peculiarity of the winder shown here is that the length of the sleeves 18 is not greater than the smallest candidate width of the wound strip. However, since the distances between the Separierusionn 20 correspond to the respective strip width, this means that between the ends of the successive sleeves 18 in the normal case certain gaps 22 remain.
  • the sleeves 18 do not slip in the longitudinal direction on the comb shaft 16, the comb shaft at least at one point of its circumference on a radially expandable clamping member 24, which extends over the positions of all the sleeves 18.
  • the clamping member 24 is formed in this example by a pneumatically inflatable bellows or hose made of rubber-elastic material, which is housed in a longitudinal groove 26 of the comb shaft 16 and connected via radial bores 28 with a central axial bore 30 of the comb shaft.
  • Fig. 1 shows, the comb shaft 16 at one end to a compressed air port 32 which can be coupled to a source of compressed air to expand the clamping member 24 so that it rests against the inner peripheral surfaces of the sleeves 18 to clamp this on the comb shaft 16.
  • the compressed air port 32 may include a manually openable check valve which maintains the pressure in the clamping member 24 when the compressed air source is disconnected. When the positions of the sleeves 18 are to be adjusted, the check valve is opened so that the tendon 24 collapses.
  • the compressed air source can also be coupled via a rotary feedthrough to the axial bore 30 of the comb shaft.
  • a longitudinal cutting system is shown schematically in a plan view.
  • a longitudinal cutting device 34 and the in Fig. 1 shown rewinder, of which in Fig. 3 for clarity, only the comb shaft 16 is shown.
  • the longitudinal cutting device 34 has a knife shaft 36, which runs parallel to the comb shaft 16 and is equipped with plate knives 38. Another, equipped with counter knives knife shaft lies in Fig. 3 invisible behind the knife shaft 36 shown.
  • the longitudinal cutting device 34 includes a robot 40 which serves to position the knife blades 38 on the cutter shafts.
  • the knife shafts 36 each have a radially expandable clamping member with which the knife blades 38 can be fixed in the respective set axial position on the shaft. After releasing this clamping member, the knife blades can be moved by means of the robot 40 on the blade shaft 36.
  • the robot 40 has a guide rail 42 running parallel to the cutter shafts 36, on which a carriage 44 can be moved by means of a numerically controlled drive.
  • the carriage 44 has a knife shafts 36 cross-arm 42 which carries not shown in detail, extendable and retractable tools for moving the knife blades 38.
  • a band 48 of the web material to be cut is inserted from the right in FIG Fig. 3 supplied to the cutting device 34 and divided by means of the disc knife 38 into individual strips 50, which continue to run to the rewinder, where they are guided by the separating discs 20 of the comb shaft 16 and finally wound onto the winding shaft 10.
  • the strips 50 fan out in the distance between the slitter 34 and the winder.
  • the distance between the slitter and the winder is such that the consequent lateral deflection of the strips 50 remains so small that the strips do not tear.
  • the desired strip widths are entered into the numerical control of the robot 40. For different strips 50 different widths can be entered.
  • the clamping members of the knife shafts 36 are released, and the carriage 44 travels along the guide rail 42 to the predetermined positions by the numerical control to position, with its jib 46, the individual jaw knives 38 in accordance with the programmed-in strip widths.
  • the plate knives are then tightened in the set positions, and the carriage 40 moves back to its rest position.
  • a gauge 52 can be used as an aid, which specifies the desired spacing between the adjacent separating discs 20.
  • the sleeves 18 are fixed by means of the clamping member 24 in the adjusted positions.
  • the belt 48 is threaded into the cutter 34 and the cutter is briefly put into operation to cut the strips 50 to a length sufficient to adhere the free ends of these strips to the hubs 12 of the winding shaft 10. Thereafter, the cutter 34 and the rewinder are put into operation, so that the tape 48 is continuously cut into the strips 50, which are then wound on the winding shaft 10.
  • Fig. 4 shows a longitudinal cutting machine according to another embodiment in a state in which the sleeves 18 are positioned on the comb shaft 16 during the setup phase.
  • a laser 54 is mounted on the carriage 44, the laser beam 56 is oriented exactly at right angles to the axes of the cutter shafts 36 and the comb shaft 16 and directed to the comb shaft 16.
  • the laser beam 56 thus forms a position indicator in the form of a light spot, which indicates how the sleeves 18 are to be positioned on the comb shaft 16.
  • the marked Light the position to which the remote from the separating wheel 20 end of the sleeve 18 is to be adjusted.
  • the numerical control of the robot 40 automatically calculates the target positions for the separating discs 20 based on the previously inputted and stored positions of the disc knives 38, taking into account the in Fig. 3 Fanning the strips 50.
  • the carriage 44 is then moved stepwise so that the laser beam 56 successively indicates the desired positions of the individual sleeves 18.
  • a sleeve 18 (at in Fig. 4 lower end of the comb shaft 16) has already been set to the desired position, while most of the remaining sleeves are still pushed together to save space at the opposite end of the clamping shaft.
  • a sleeve is just moved to the dot-dashed set position.
  • the clamping member 24 formed by a bellows or tube of the comb shaft 16 may be configured so that it protrudes slightly out of the longitudinal groove 26 even in the unexpanded state and so the displacement of the sleeves 18 opposes a certain frictional resistance, which is just large enough Keep sleeves in the set position until they are finally fixed by expanding the clamping device.
  • the laser 54 or a separate laser, not shown, can be used to adjust the positions of the winding cores 12 on the winding shaft 10 in a corresponding manner.
