Definitions

  • the invention is directed to a device of the type specified in the preamble of claim 1.
  • An important application of such devices is a loom, where initially a wide fabric is produced with multiple juxtaposed patterns, which then cut on the loom at the transition point between two adjacent patterns to make a variety of tapes.
  • a preferred field of application of such tapes are textile labels which are made in an identical manner sequentially in each tape. These labels are finally separated by cross-cutting the tapes and attached to objects, especially on garments.
  • Such bands can be made very narrow and in extreme cases have only a few millimeters of bandwidth.
  • a web is wound on a continuous winding star.
  • different holding members were used to detect the web starting piece, but these holding members had to be attached by special measures of various types on the winding core. After completion of the winding, the support member was no longer removable and remained as an integral part of the winding core. For this attachment of the insert, there were the following different possibilities in the prior art.
  • a third way to secure a holding member is from the JP 2000 185 A known, for which a two-legged U-bracket is used.
  • This bracket has two legs of different lengths, which in two mutually diametrical grooves of a Winding body are pushed axially. The one, long leg to hold the web to be wound on the bobbin, while the other leg to hold the long leg in the groove of the winding body at the beginning of winding, a radial insertion of the two legs of the bracket is neither provided nor possible. This complicates the fixation of the web initial piece and is not applicable to several, adjacent bands that are to be wound up at the same time.
  • a fourth way to attach a retaining member shows the JP 2000 272 788 A ,
  • a clamping bar is used as a holding member to fix the initial part of a film in a clamping groove of a winding body.
  • the terminal strip here has resilient foot pieces which cooperate in use with a corresponding counter-profile in the interior of the clamping groove and are locked there. This clamping does not allow, after completion of the film roll, the terminal strip axially pulled out of the film reel again.
  • the invention has for its object to develop a take-up textile tapes for devices mentioned in the preamble, in which the tapes can be quickly and reliably attached to their associated functioning as a hub rings, even if the tapes are very narrow are.
  • This is inventively achieved by the measures listed in claim 1, which have the following special significance.
  • the invention proposes to use a stack of discs instead of the rings, which have mutually axially aligned cutouts at their disc edge. These cutouts each have a narrowed inlet opening in relation to their subsequent, concavely widened inner profiles. These cutouts form a first element of a two-part fastener for the band or beginning pieces.
  • the second element of the fastener consists of a loose insert that is common to the cutouts in the disc stack.
  • the cross section of the insert is opposite to both the cutout entry openings and the cutout inner profiles designed in a special way.
  • the cross-section is formed at least temporarily and / or at least in places larger than the cutout inlet openings in the disk stack.
  • the cross-section is smaller than or equal to the cutout inside profiles. The latter ensures a sufficient clearance between the outer surface of the insert and the inner surface of the cutout inner profiles, which is very significant for the yet to be dismantled dismantling of the finished tape roll from the shaft.
  • the insert is inserted radially through the cutout entry opening into the cutout inner profile, takes the tape starting pieces with them and fixes them in the stack of disks.
  • the abovementioned reduction of the insert cross-section with respect to the cut-out entry openings is only present during radial insertion.
  • the insert cross-section is in any case designed to be larger than the cut-out openings, which automatically prevents radial extraction of the insert and secures the position of the tape initial piece (s) on the disk stack.
  • the individual disks in the stack are rotatably coupled with each other by the use. This ensures a compliant rotation of all coupled discs.
  • the insert is pulled axially out of the cutout inner profiles of the disk stack, ie parallel to the shaft. Then the discs in the stack are uncoupled from each other and divided into sub-packages. Although these sub-packages with the tapes wound thereon consist of several discs, but each pack form a tape roll that holds only the associated discs together. The withdrawn insert can be reused in a future disc stack.
  • Fig. 4 of the device is shown only the mechanical part of the provided at its output winding device with the most important components.
  • the shaft 11 can be rotated by a drive in the sense of the rotary arrow 12.
  • the take-up device 10 should be arranged at the output of a loom for a discernible in Fig. 6 wide fabric 40, which after weaving still on the loom in the individual bands 15 is cut.
  • the cut edges 47 of the bands 15 can be seen. If the thread material of the bands 15 includes thermoplastic materials, the cutting process is done by heated cutting wires.
  • the feeder 13 comprises three rollers 16 to 18, of which two rollers 16, 17 are rotatably mounted at the free end of a pair of arms 14, which hold the apparent from Fig. 6 crowd of bands 15 between them.
  • the two guide rollers 16, 17 are rotationally driven in coordination with the deduction of the wide fabric 40 and transport the belts 15 in the direction of the arrow 41 in the direction of the shaft 11.
  • the supply 13 also includes an idler roller 18, which is for a pressure of the belts 15 at the output side guide roller 17 ensures.
  • the idle roller 18 is loosely between the two guide rollers 16, 17, which are driven either indirectly indirectly via the conveyed belts 15 or directly.
  • the idle roller 18 is rotated during transport 41 of the bands 15.
  • the opposite end of the arm pair 14 is pivotally mounted at 19 on the frame not shown in detail of the device parallel to the shaft 11.
  • the two arms 14 are connected to each other by traverses 42 and thereby pivotally together in the sense of the movement arrow 43.
  • a stationary stop 44 on the frame of the device holds the pair of arms 14 in a defined starting position relative to the shaft 11.
  • the shaft 11 is part of the weaving machine and serves to wind the woven product, namely here cut into strips 15 Breitware 40th
  • the winding device 10 is formed as a ring disc 21, which serves as a core for winding the individual bands 15.
  • the disk 21 is flat and has only a disk thickness 22 of e.g. only 2 mm.
  • the disc 21 has a central aperture 23 forming an annular opening.
  • the opening 23 has an inner profile 26, which is complementary to the recognizable from Fig. 4 circumferential profile 46 of the shaft 11 is formed.
  • the wave perimeter profile 46 is out-of-round in order to take a crowd of discs 21 mounted thereon on a shaft rotation 12.
  • the shaft 11 in the present case has a profile and is designed as a square profile. Therefore, the central opening 23 of the disc 21 is a square hollow profile 26th
  • the initial pieces 45 of the bands engage over the associated disks 21.
  • the bands 15 have a bandwidth 48 that is greater than the disk thickness 22 according to FIG. 2 of each individual disk 21.
  • all bands 15 have a matching width 48. This is so dimensioned that in each case three annular discs, which are marked in Fig. 6 with 21.1, 21.2 and 21.3, must be used as a future hub of an associated band 15.
  • the band-starting pieces 45 are fixed in a special manner on the ring circumference 27 in the invention.
  • Each disc has four cutouts 28, which are in radial Alignment with the square hollow section 26 of the disc 21 are positioned. As can be seen from Fig. 1, the cutouts 28 are each in radial alignment with the longitudinal center of one of the four profile sides 39 from the hollow profile 26 of the disc 21. Consequently, as shown in FIG. 6, after arbitrary stacking of the discs 21 on the Shaft 11 all cutouts 28 of the disc stack 24 aligned axially parallel to the shaft 11.
  • the cutouts 28 are located in the outer edge of the pane.
  • the aforementioned central position of the cutouts 28 to the square hollow section 26 of the annular breakthrough 23 causes there, as shown in FIG. 1, just the maximum annular disk height 38 is present. Therefore, it is possible to cut the cutouts 28 at the expense of the annular disc height without endangering the stability of the ring.
  • a sufficiently large remainder 37 remains at the annular disc height.
  • an insert 30 which in the present case consists of a substantially rigid rod 31, which is shown in FIG.
  • the rod 31 functions as a common insert for the cutouts 28 of all the disks 21 which are positioned on the shaft 11.
  • Fig. 6 shows in detail in Fig. 5b.
  • the respective starting piece 45 of the band 15 is laid over a narrowed entry opening 29 of the associated cutout 28 in the annular disc 21.
  • the rod 31 is pressed in the direction of the arrow 32 into the interior of the receptacle 25.
  • the band-starting piece 25 is clamped between the concave inner surface 25 of the cutout 28 and the convex peripheral surface 33 of the rod 31.
  • the cutout 28 and / or the rod 31 may be at least locally edged. As shown in FIG. 7b, the following situation then exists.
  • the rod 31 has in Figs. 3 to 8b a circular cross-section 34 which is matched with the inner profile 25 of the cutout 28.
  • Fig. 7b the rod 31 is sunk more than halfway in the cutout 28 of the respective disc 21.
  • the apparent in Fig. 7b sinking depth 35 is almost three quarters of the diameter of the circular cross-section 34 of the rod 31 of FIG. 4b. It comes to elastic Deformations from the concave profile of the receptacle 28. This deformation takes place above all in the region of diametrically, elastically yielding latching lugs 36, which delimit the inlet opening 29 according to FIG. 5b.
  • the entrance opening 29 of the annular disc 21 is made smaller.
  • the continuous rod 31 also ensures a coupling between the adjacent annular discs 21 in the stack 24.
  • the locking lugs 36 are miterzeugt. This can e.g. by cutting the profile shape of the disc 21 shown in Fig. 1 made of a plastic plate. It offers itself to a computerized water jet cutting technology. Of course, other ways of making are conceivable, e.g. an injection molding process.
  • a coil 50 illustrated in phantom with its circumference, of the individual belts 15 on the disks 21 associated therewith, finally emerges.
  • the respective band 15 are wound on three annular discs 21.1 to 21.3.
  • the rod 31 is radially covered by a plurality of juxtaposed tape roll 50, but axially accessible. As illustrated in FIG. 6, the rod 31 can have an excess length 54 with respect to the disk stack 24 and protrude axially with an end piece 55 from the finished windings 50 of FIG. 8a. The rod 31 can therefore be detected at this end piece 55 and pulled axially in the direction of the arrow 56 of FIG.
  • Sub-packages 57 from associated annular disks 21.1 to 21.3 of the individual bands 15 are then decoupled from each other.
  • the seated on these sub-packages 57 tape-winding 50 of FIG. 8a are therefore separated from each other and can be withdrawn in packets from the shaft 11.
  • the above-mentioned elastic deformations between the insert 30 and the cutout 28 need not only be made by the elastic material in the region of the concave profile of the cutout 28, but may additionally or alternatively be done by a deformation of the cross section of the insert 30. In this case, of course, a latching between insert 30 and ring 20 can be generated. A first possibility would be, even the insert 20 radially deformable train. In addition, the following design is possible, which is not shown in detail.
  • the cross-section of such a hose or pipe will be kept to a minimum, as described in FIG. 5b, in the case of the above-described radial impressions 32, then, after the coupling according to FIG. 7b, it will increase.
  • the contact pressure in the inner profile 25 is transformed into a lateral play of the insert in the cutout 28.
  • the above-described axial withdrawal 56 of the insert from the individual band windings 50 is very smooth.
  • the above-described change of the outer diameter can be easily generated in a pipe or hose in that one fills the expansion of the outer diameter into the interior of a pressure medium.
  • the pressure medium then exerts a controllable internal pressure in the radially elastic tube or tube, which produces the desired change in the outer diameter.
  • FIGS. 9a to 9c a second exemplary embodiment of an insert is shown in FIGS. 9a to 9c, which in this case too is designed as a substantially dimensionally stable rod 31 '.
  • the take-up device 10 'in Fig. 9a to 9c in analogy to the first embodiment of Fig. 1 to 8b to be formed.
  • the annular disc 21 ' should be designed identically to the annular disc 21 of the first embodiment. Therefore, the same reference numerals as in the first embodiment will be used to designate the same constituents, but to distinguish the reference numerals in the second embodiment with a dash ('). In that regard, the previous description applies. All you have to do is address the differences.
  • the rod 31 ' has a circumference 58 in the predominant region of its cross section, but the cross section in the rest of the outline region designated by 59 in FIG. 9a is delimited by a plane 59.
  • the two directions 65, 66 to each other perpendicular.
  • the one direction marked 65 to be referred to as the "main direction”
  • the second direction 66 which should be referred to as “secondary direction” extends a smaller residual diameter 62, which results from the difference between the full diameter 61 and the radial height 69 of the segment 64.
  • the annular disc 21 ' may consist of substantially inelastic material, where the entry opening 29' of the cutout 28 'is bounded by rigid lugs 26'.
  • the clear width of the inlet opening 29 ' is formed smaller than the full diameter 61 of the rod cross section 63 corresponds. Nevertheless, the band starting piece 45 'can be introduced into the interior of the cutout 28' by a so-called raising movement 60.1, 60.2 and secured there.
  • the aforementioned Einrenkterrorism is characterized by two, successive mutually different motion phases 60.1, 60.2, namely an initial phase 60.1 and a final phase 60.2.
  • the initial phase of the Einrenkterrorism illustrated by a Einsteckpfeil 60.1 in Fig. 9a takes place.
  • the rod cross-section 63 is oriented with its main direction 65 in the insertion direction.
  • the rod 31 ' only with its minimum residual diameter 62 with the clear width of the Entry opening 29 'oriented. Therefore, the rod 31 'between the fixed projections 36' can be easily brought into the inner profile 25 of the cutout 28 'according to FIG. 6b. It is understood that the inside width of the entry opening 29 'is less than / equal to the remaining diameter 62 plus the two-sided layers of the strip thickness 67 illustrated in FIG. 9b.
  • the linear initial phase 60.1 of the insertion movement has ended, then the final phase 60.2 of the insertion movement commences.
  • This consists of an illustrated by an arrow 60.2 in Fig. 9b rotation, which is 90 ° in the present case.
  • the main direction 65 and the secondary direction 66 of the non-circular rod cross-section 63 interchange their position with respect to the inlet opening 29 'of the cutout 28'.
  • the rod 31 ' is oriented with its full diameter 61 parallel to the inlet opening 29'.
  • FIG. 9c is dash-dotted lines at 68, the continuation of the ring circumference 27 'of the disc 21' illustrates.
  • the wound on the disc 21 'tape layers do not press against the secured rod 31'.
  • An axial withdrawal inhibiting frictional action between the band wraps and the planar peripheral portions 59 of the rod 31 ' is thereby eliminated.
  • the rod 31 ' can be easily pulled out in Fig. 9c.
