Definitions

  • the invention relates to a device for exchanging a winding core wound with WickeTgut.
  • a memory into which the material to be wound enters during the exchange process.
  • a memory can be realized, for example, by one or more dancer rollers which, when spread apart, lengthen the path that the winding material has to go through and thus show memory behavior (cf. e.g. DE-OS 27 51 829, Fig. 1, item 16).
  • this has the disadvantage that a relatively expensive and additional dancer roller device is required.
  • the invention has for its object to provide a device for exchanging a winding core wound with winding material against an unwound winding core without interrupting the feeding of the winding material, which has a device for the horizontal transport of the winding core, in which from the input of an empty winding core to Output of the wound winding core an exact guidance of this winding core is guaranteed.
  • This object is achieved in that the winding core is released in a first end position and the winding core is received in a second end position of the winding core.
  • the advantage achieved with the invention is, in particular, that the insertion of empty winding cores and the removal of the wound winding cores can take place fully automatically.
  • a safe winding of the winding material is guaranteed, even if the web to be wound is divided into several partial webs, so that several narrow rolls are wound at the same time.
  • Another important advantage of the invention is that the vertical and horizontal guidance of the winding core consists of the same elements, so that practically one guide performs two functions.
  • the Fig.la shows a schematic plan view of a roll 1 containing the material to be wound, which is located on a winding core 2.
  • the two ends 3, 4 of the winding core 2 are inserted into two circular rods 5, 6 and 7, 8, respectively, which are moved in the direction of the arrow by means of a circulating belt 9, 10, which can be formed, for example, by a circulating chain. So that the ends 3, 4 of the winding core 2 can be inserted between the rods, they have corresponding lateral recesses, preferably in the form of quarter circles.
  • the belts 9, 10 are driven by means of an electric motor 11, which drives the belt 9 directly and the belt 10 indirectly via a shaft 12.
  • an unwound winding core 26 can be inserted on the other side of the winding core drive, as shown in FIG. 1b. This is achieved by spreading the rods 18, 19 and 20, 21 apart. possible that are currently in the curvature.
  • the feed can take place automatically, for example by releasing a lock which retains the winding cores in a winding core magazine 27. It is of course also possible to increase the number of circular rods on the circumference of the bands 9, 10, so that practically at all times when moving Tapes can be entered from winding cores.
  • the newly inserted winding core 26 is now brought to the same place where the winding core 2 (Fig.la) was previously. It can now be wrapped in the same way as this.
  • Fig.2a the device of Fig.la according to section A-A is shown again from the side.
  • the roller 1 which is composed of the material to be wound.
  • This roller 1 is guided through the end 4 of the winding core 2 in the vertical direction.
  • the shaft 13 which is driven by the gear 13a ′, which in turn is coupled to the electric motor 12, 11 via the shaft 12, also drives the gear 13.
  • FIG. 2b shows the roller 1 in its right end position.
  • the Fig.2b thus corresponds to the section B-B of Fig. 1b, seen from the side. It can be seen from this illustration that the roller 1 is now easily removable, while at the same time the new winding core 26 can be inserted in a simple manner.
  • the shaft 13 is omitted from this illustration.
  • Figures la, lb, 2a, 2b only show the principle of vertical and horizontal guidance of the winding core 2.
  • other components are provided, which e.g. cause the winding core 2 not to slide down in the gap between the bars 7, 8.
  • Some of these components are shown in Fig. 3 described below.
  • FIG. 3 shows a completed device which in principle corresponds to the devices of FIGS. 2a and 2b, approximately in the view A'-A 'or B'-B' (FIG. Fig.lb).
  • the shaft 1 is only indicated here both in its middle position and in its end position. The end position is designated 1 'and shown in dashed lines.
  • roller 1 rests on two support rollers 30, 31 which drive the roller 1.
  • the rollers 30, 31 are in turn driven by the motor 32, which are located below the rollers 30, 31.
  • the mechanical coupling elements between the motor 32 and the rollers 30, 31 are not shown.
  • the motor 32 is provided as the main drive, while the motor 32a serves as the winding transport drive.
  • a loading roller 33 rests on the roller and can be raised and lowered by means of a loading arm 34.
  • the lifting arm 34 is raised and lowered by means of a hydraulic drive 35, on the piston rod 36 of which a deflection roller 37 is provided, over which a cable 38 runs, which is fastened at one end to a projection 39 or the like.
  • This cable 38 is connected to the load arm 34 via further deflection rollers 40, 41, 42.
  • the strip-like material 28 to be wound is passed over a first deflecting roller 43 and a second deflecting roller 44 onto the support roller 30, on which the roller 1 rests. Between the two deflection rollers 43, 44 there is a dancer 45, the roller 46 of which can assume different positions, which indicate the tensile stresses of the band-shaped material 28. An upper and a lower position are indicated by dashed lines.
  • the tensile stresses can serve in a known manner as a control variable for the winding speed, the control variable, for example an electrical voltage, being generated in a special device 47.
  • the empty winding cores are between the Brought management staffs.
  • the winding material 28 is applied to a new winding core 51 with the aid of a positioning and cross-separating assembly 52.
  • the end roller 54 of the arm 53 is designated 54 'in its upper position.
  • the new winding cores can be released automatically by unlocking a pawl 70.
  • the tape transfer from the wound roll 1 to the empty winding core 51 takes place in such a way that the new winding core 51, guided by guide rods, first reaches the roller 30 and presses the material to be wound there.
  • the arm 53 with the end roller 54 is passed through the rollers 30, 31 and it takes the winding material 28 in such a way that it is wrapped around the winding core 51.
  • the winding material 28 is now severed at point 55, so that the roller 1 is free.
  • the winding material 28 is fully gripped by the winding core 51.
  • the loading roller 53 now presses on the new winding core 51 from above.
  • the winding core 51 is then wound up in the position between the two rollers 30, 31.
  • FIG. 4 shows a variant 60 of the lay-on and cross-cut fitting 52.
  • This variant 60 has three support rollers 30, 31, 61, making it possible to dispense with guiding the arm 53 through the two support rollers 30, 31. Without the engagement of the arm 62, which is driven by a hydraulic system 63, the winding material 28 runs along the solid line.
  • This position of the arm 62 is not shown in FIG. 4, but it is understood that the roller 64 is arranged below the winding material located between the rollers 31 and 61. 4 is the Roller 1 has just been transported away from rollers 30, 31 and placed on roller 61. If the arm 62 now grips its roller 64 upward, it wraps around the winding material 28 'of the new winding core 51 in the manner shown in dashed lines.
  • the winding material 28 and the opposing winding material touch at point 65.
  • the winding material 28 ' is cut, for example at point 66, with the aid of a cutting knife 67, so that the roller 1 can be removed and the end of the winding material 28' over loops around the winding core 51.
  • the present invention is not limited to the exemplary embodiment shown in the figures.
  • other drives for the transport of the winding core 2 can also be provided if they only meet the condition that the winding core is guided exactly horizontally and vertically without it jamming.
  • the winding core does not have to be rigid or continuous in every case. Rather, it can e.g. Contain springs which make it possible to compress the winding core somewhat in its longitudinal axis, so that the winding core can also be inserted in the position shown in the Fig.la. This would make it possible to insert or remove the winding core even when the drive is at a standstill.
  • the decisive advantage can be achieved that an exact guidance of the winding core is possible due to the vertical parallel guide rods. With an inclined vertical guide, it would not be possible to wind up exactly. Since the present invention can be used for wound rolls of the order of 1.50 m in diameter and more, the imprecise windings would have an increasingly disruptive effect with increasing diameter.
