Definitions

  • the innovation relates to an unwinding device for rings of winding goods of the type specified in the preamble of claim 1, cf. e.g. EP-A1 196 614.
  • Such unwinding devices offer the advantage of being able to pull off strands largely without twist from the rings of the winding goods placed thereon, since the ring lying on the turntable can rotate counter to the winding direction of the winding material in question due to the pulling forces.
  • the adjustability of the support members in the radial direction to the axis of rotation of the turntable is used to be able to receive coils of different inner diameters centered on the turntable.
  • Unwinding devices similar to the generic type are also known on the market, see for example US Pat. No. 2,557,510, in which the radially adjustable support members on the turntable consist of clamping bolts which are guided in straight, approximately radially extending slots of the turntable and with an adjustment device arranged under the turntable are connected.
  • the disadvantage of such unwinding devices is a lack of stability of the upwardly projecting clamping bolt and in relatively long adjustment paths, which is due to the linear guidance of the clamping bolt, making the adjustment of the clamping bolt cumbersome and lengthy.
  • the innovation is therefore based on the object of creating an unwinding device of the type mentioned at the outset, which has greater stability and offers a simpler, faster adjustment possibility.
  • the particular advantage of an unwinding device is that the swivel slats themselves can be made sufficiently rigid and can be supported on both ends of the winding core, which results in very good stability.
  • the swivel adjustment of the slats enables a simple swivel device with short adjustment paths.
  • the pivot axis expediently passes through one of the two side edges of each swivel plate, so that the largest possible swivel arc results in relation to the respective swivel angle on the side edge of the plates opposite the mounted side edge. So that the free side edges are supported in a uniform sequence on the inner sides of the rings to be received, the swivel blades are advantageously arranged in a rotationally symmetrical manner in the circumferential direction of the winding core.
  • the outer sides of the swivel slats represent jacket sections of a cylinder.
  • the swivel slats complement each other with their outer sides to form a continuous cylindrical jacket surface which forms the outside of the winding core.
  • the swivel slats are suspended between the turntable and a disk arranged parallel above it, which is firmly connected to the turntable.
  • On this disc is an adjustable disc accessible from above, which is coupled to the individual slats via a swivel gear.
  • the adjusting disk expediently forms the upper end of the winding core and has suitable handle elements on the top side, via which an easy and quick access for actuating the core adjusting device is possible.
  • the swivel gear is advantageously designed such that the pivoting of the slats is effected by turning the adjusting disk.
  • a suitable locking device is expediently provided on the adjusting disk in order to prevent inadvertent rotation of the swivel slats, in particular as a result of radial loading.
  • Figures 1 and 2 show the basic structure of the essential elements of an unwinding device for coils wound in a ring.
  • a turntable 1 which is oriented horizontally in the usual position of use and whose axis of rotation is correspondingly vertical.
  • the turntable 1 consists essentially of a disc-shaped body with a flat upper side which has embossed beads 2 for stiffening.
  • a winding core 3 is arranged coaxially upwards on the turntable 1, the height of which essentially depends on the axial length of the winding material rings to be accommodated.
  • the effective diameter of the winding core 3 can be changed. It consists of three swivel blades 4, the straight in the vertical direction, zueinan the parallel side edges 5 and 6.
  • the pivot axis 14 of the slats 4 is close to the one side edge 6 mounted, while the opposite side edge 5, seen as a free edge in the vertical projection, can be pivoted outwards along an arc of a circle and forms a support line or surface for the relevant winding material ring.
  • the swivel plates 4 have an outer side 7, which represents the section of a cylinder jacket. Since all the lamellae 4 are the same and extend along the arc at an angle of 120 °, the outer sides 7 of all the lamellae 4 complement one another in the pivoted-in end position to form a closed cylindrical surface, which forms the outer surface of the winding core 3. In this position of the swivel blades 4, the winding core 3 has its smallest diameter, which is also the outer diameter of the cylinder mentioned.
  • the pivoting slats are pivoted counterclockwise, the effective diameter of the winding core 3 increases. Since in the pivoted-out position, the pivoting slats 4 only have a limited area of their outside 7 near the free side edge 5 form a support surface for the coiled material rings, axially parallel grooves or ribs 8 can be provided here for better entrainment of the winding core 3 and thus of the turntable, the outside 7 of the slats 4 being stronger than in the region of these grooves or ribs 8 up to the free side edge 5 the rest of the cylindrical area can be curved.
  • the swivel slats 4 consist of hollow profiles, for example of extruded profiles that can be cut to length, which have an outer wall 9, an inner wall 10 and intermediate stiffening ribs 11.
  • the outer wall 9 forms with its outer surface the outside 7 of the swivel slats 4, while the hollow chambers of the profile can be used to accommodate bearing elements and the like.
  • the swivel plates 4 are suspended between the turntable 1 and a disk 12 which is arranged at a suitable distance above the turntable 1.
  • the disc 12 is connected to the turntable 1 via a column 13 which is arranged coaxially, but is not absolutely necessary for supporting the disc 12.
  • Circular arc slots 15 are arranged in the disk 12, through which drive pins 16 pass.
  • the Driving pins 16 are connected outside of the pivot axis 14, that is to say eccentrically, to the respectively associated pivot plate 4, although they are axially parallel to the pivot axis 14.
  • the length of the circular arc slots 15 corresponds to the maximum swivel angle of the swivel slats 4, which is limited by the stop of the driving pins 16 at the ends of the circular arc slots 15.
  • An adjusting disk 17 is mounted coaxially to the disk 12 and can be rotated relative to the disk 12 underneath. On its underside, the adjusting disk 17 has control slots 18 which run along circular arcs and into which the driver pins 16 of the slats 4 engage. In Fig.
  • the point of engagement of the driver pins 16 in the control slots 18 is marked in the open position of the slats 4 shown, if the adjusting disc 17 is rotated in the direction of the arrows shown from this position, the slats 4 pivot inwards. So that the adjusting device can be actuated easily, the adjusting disk 17 has one or more grip elements 19 on its upper side, which can be formed, for example, by a correspondingly shaped surface contour or incorporated holes.
  • the swivel plates 4 designed as hollow bodies have a through opening 20 in the direction of the swivel axis 14 near their stored side edge 6, which receives a bearing tube 21 running relative thereto.
  • the bearing tube 21 is slightly above and below the top and bottom Lower edges of the swivel slats 4 in front and is firmly connected to the upper disc 12 and to the lower turntable 1.
  • the disc 12 is essentially firmly connected to the turntable 1 via these bearing tubes 21, which is why the central column 13 as a support element is in itself unnecessary.
  • the bracing between the disk 12 and the bearing tubes 21 takes place via screws 22 which are guided through the disk 12, in the same way the lower turntable 1 is firmly connected to the bearing tubes 21 via screws 23.
  • the swivel plates 4 are rotatably mounted on the bearing tubes 21, with adequate spacing being provided by suitable intermediate rings on the projections of the bearing tubes 21 both upwards to the disc 12 and downwards to the turntable 1, so that the plates 4 contact-free with respect to the disc 12 and the turntable 1 can be pivoted.
  • the hollow swivel blades 4 have further through openings 24 parallel to the through openings 20 in the direction of the swivel axis 14, in which the drive pins 16 are firmly inserted.
  • the adjusting disc 17 is not only rotatable relative to the underlying disc 12 but also axially displaceable. For this purpose, it has a firmly cast-in axle pin 25 which projects coaxially downwards. This axis pin 25 engages in a central bore of the disc 12 in which it is guided axially. Between the disk 12 and the adjusting disk 17, a compression spring 26 is arranged coaxially to the axle pin 25, which strives to adjust the adjusting disk 17 to push away from the lower disc 12 at the top.
  • the axle pin 25 has a radially projecting coupling part 27 which has form-locking elements on its side lying towards the disk 12.
  • the disk 12 also has corresponding positive locking elements on a mating coupling part 28 which is in engagement with the coupling part 27 on the axle pin 25 of the adjusting disk 17 as long as the adjusting disk 17 is in its upper, disengaged end position. In this position, the adjusting disk 17 is locked in relation to the lower disk 12 and cannot be rotated. If the adjusting disk 17 is depressed, the coupling part 27 and the counter-coupling part 28 come free from one another, after which the adjusting disk 17 can be rotated in order to cause the swivel plates 4 to pivot.
  • the arcuate slots 18 are arranged and designed on the underside of the adjusting disk 17 such that the driver pins 16 do not come out of engagement with them even in the upper, disengaged end position of the adjusting disk 17.
  • the adjusting disk 17 is designed in the manner of a cap with a collar 29 projecting coaxially downward and thus overlaps the disk 12 underneath.
  • the stroke of the adjusting disk 17 can be limited by a step on the inside of the collar 29.
  • a bead 3o Arranged on the circumferential side of the collar 29 is a bead 3o which projects radially outwards and which, in the pivoted-in end position, still extends over the outer sides 7 of the swivel blades 4 protrudes. It is used to guide the strand during so-called inner unwinding, when a coil placed on the unwinding device is pulled from the inside when the swivel blades are retracted after the centering process.
  • the unwinding device has a frame 31, the details of which are shown overall in FIGS. 3, 4 and 5.
  • a support 33 lying diametrically to the turntable 1 lying above it is adjoined, at right angles, opposite one another by two cross supports 32, which, as seen in the vertical projection, are arranged approximately tangentially to the turntable 1.
  • a bow-shaped support tube is attached to the end of the cross member 32 and extends upwards, as can be seen in FIG. 3, over the top of the turntable 1 and forms a railing 34.
  • the railings 34 serve both as a support bracket to be able to lift the entire unwinding device and as a side limitation.
  • rubber buffers 35 are inserted as feet; instead, castors and / or fixed castors can also be provided.
  • a brake drum 36 protruding downward is arranged above the frame support 33 on the underside of the turntable 1 and can also be seen schematically in FIG. 6.
  • a brake pad 39 arranged on a brake lever 37 can be brought into contact therewith in order to block the turntable 1 as long as a strand is not being pulled off a roll lying thereon.
  • the brake lever 37 be sits between its outer end and the brake pad 39, a pivot bearing 38, a tension spring 4o engages at a distance from this pivot bearing 38, which is mounted on the frame support 33.
  • the tension spring 4o acts solely on the brake lever 37, a maximum braking force is applied to the brake drum 36 of the turntable 1 via the brake lining 39.
