Definitions

  • the invention relates to a winding device according to the preamble of claim 1.
  • a winding device is used for winding threads e.g. by DE-OS 26 45 220 (Bag. 1001) and by EP-A 176020 (Bag. 1429) known.
  • the centering plates are mounted on the free ends of parallel holding arms.
  • the axial spring force with which the centering plates are pressed against the end face of the winding tube is applied in that at least one of the holding arms is perpendicular to the winding axis in addition to the two common pivoting movements perpendicular to the winding axis crossing pivot axis is pivotable against spring force.
  • At least one of the centering plates is movable on the winding axis relative to its holding arm, the centering plate being supported on its swivel arm by a threaded connection or a spring connection.
  • the centering plate is not exactly on one axis (misalignment); the winding tube is not exactly centered on one or both centering plates (centering error); the centering plate is not exactly parallel to the face of the winding tube (wobble error).
  • the embodiment according to claim 2 is characterized by its simple structure and its low mass and robustness.
  • the embodiment according to claim 3 can be developed according to one of claims 4 to 6.
  • the winding tube 1 is held by the two clamping plates 2 and 3. These are rotatably attached to arms 4 and 5, respectively.
  • the arm 5 consists of two hinged levers 6 and 7.
  • the front, designated 6 Lever serves as a brake lever, whereas the rear lever, designated 7, works as a clamping lever.
  • the brake lever 6 is connected to the clamping lever 7 in such a way that when the lever 6 swivels outwards - after bridging a small free travel - the lever 7 is carried along by the stop 10.
  • the clamping lever 7 is articulated (pivot point 12) to the support plate 8, whereas the holding arm 4 is rigidly attached to this support plate.
  • the support plate 8 itself is rotatable about the axis 9.
  • the axis 9 is arranged parallel to the longitudinal axis of the machine and is fixed rigidly in the machine frame. Instead of the axis, it is of course also possible to choose any other rotary fastening.
  • the brake lever 6 is pivoted outward about its pivot point 11, whereby the clamping lever 7 is also pivoted about its pivot point 12.
  • the clamping lever 7 is rotated back into its operating position by the tension spring 13.
  • the tension spring 13 is designed so that it is ensured that the winding tube cannot slip off the clamping plates during the winding process.
  • the winding tube is driven in operation by a drive roller, not shown here. After the winding process is complete, the winding tube with the winding is lifted off the drive roller. In order to be able to change the bobbin, it is necessary to brake the bobbin, which is still rotating.
  • a further tension spring 15 is used between the brake lever 6 and the clamping lever 7.
  • the brake lever 6 is again pivoted outward from the bobbin tube 1 so that the clamping lever 7 is also rotated via the stop 10 so that the bobbin tube can be removed or fall into a collecting device arranged below the bobbin tube holder.
  • the centering plates 2 and 3 are designed as follows:
  • Pins 16 are cantilevered on the holding arms 4 and 7.
  • the pins have a thread and a collar 18 at one end.
  • Screw 17 is used to clamp the pins 16 in a hole in the holding arm - only the holding arm 7 is shown in FIGS. 1, 2.
  • the pin has a crowned end.
  • a bushing 19 sits on this crowned end.
  • the bushing 19 has an inner surface which is matched to the crowning of the pin 16. It is slit along a surface line and can therefore be resiliently widened to be plugged onto the pin 16.
  • the ball bearing 20 is seated on the bushing 19.
  • the ball bearing 20 is axially fixed on the bushing 19 by suitable collars and rings.
  • the hub 21 sits freely rotatable Centering plate, again axially fixed by suitable rings and stops.
  • Attached to the hub 21 is, on the one hand, the radial brake disk 28, which cooperates with the brake pad 14 on the brake lever 6 to brake the centering plate; furthermore a ring of joint rods (spring rods) 22.
  • the spring rods 22 are spring-jointed on a normal plane of the hub, in such a way that they lie in the rest position on the imaginary outer surface of a cone, which has its base in the region of the winding tube 1.
  • clamping ends are aligned such that they lie on an imaginary cone jacket, the tip of which points in the direction of the axial center of the winding tube 1.
  • the clamping ends 23 are arranged in the unloaded state of the centering plate or spring bars 22 on an imaginary cylinder jacket, the outside diameter of which is smaller than the inside diameter of the sleeve 1.
  • the stop pieces 26 adjoin the clamping ends 23. These are short extensions of the clamping ends 23, which are aligned essentially radially. It is shown that the spring bars, clamping ends and stop piece are each part of a one-piece, sheet-shaped tongue.
  • arm 7 in FIG. 5 is first pivoted in the sense of increasing the distance between the two centering plates 2 and 3. Now a winding tube 1 can be held between the centering plate. Arm 7 is now pivoted back into its starting position. Here, it is under the force of the spring 13. When pivoting back, the end faces of the winding tube 1 - as shown in FIGS. 1A, 2A - hit the stop pieces 26. In response to the spring force 13, the stop pieces 26 become those shown in FIG. 1C Position swiveled. The stop pieces, which are initially at an angle, are pivoted and raised in the direction of the normal plane of their joint 29.
  • the spring bars 22 also apply part of the reaction force to the spring force 13. In essence, this reaction force is built up in that the free ends 24 and centering pieces 25 against the inside Place the circumference of the winding tube 1.
  • the articulated rods were designed as spring rods only because an articulated connection between the hub 21 and the rods 22 can be easily achieved in this way.
  • the centering plate can also be aligned with the axis of the winding tube.
  • centering plate Due to the special design of the centering plate, wobble errors and out-of-roundness errors during the clamping of the sleeve are avoided.
  • misalignments between the opposite centering plates can also be compensated. Such misalignments occur e.g. regardless of the design tolerances, also due to differences in length between the winding tubes to be processed.
  • a pin 16 is fastened to the holding arms (for example 7).
  • the pin 16 has a thread and a collar 18 at its free end.
  • the pin 16 is thus clamped in a hole in the holding arm 7 by means of screw 17.
  • a spherical ball bearing 20, which is axially fixed by a screw, sits on the projecting pin.
  • the circular cylindrical hub 21 of the disk-shaped centering plate 2 sits on its outer ring.
  • a bush 30 with the disk-shaped centering piece is slidably guided on the hub 21.
  • the bushing 30 and the centering piece can be made in one piece.
  • the socket 30 has a spherical outer contour and the central hole of the centering piece 25 also has a spherical contour.
  • the spherical bush 30 has an axially parallel slot, not shown, so that its diameter can be resiliently reduced.
  • the disk-shaped centering piece 25 sits on the spherical outer contour of the bush 30.
  • the centering piece 25 can be pushed onto the bush by resilient compression of the bush 30 and can then be pivoted on the bush.
  • the outer contour of the centering piece 25 is conical, the cone tip pointing in the direction of the axial center of the winding tube 1.
  • the centering piece is axially pressed off from the centering plate 2 by a plurality of compression springs 27 distributed over the circumference.
  • the outer circumference of the centering plate 2 is formed by a stop piece 26.
  • This stop piece 26 is annular and is placed on the outer edge of the disk-shaped centering plate.
  • the inner circumference of this annular stop piece 26 is somewhat larger than the largest outer circumference of the centering piece 25 and smaller than the outer circumference of the winding tube 1.
  • the smallest diameter of the centering piece 25 is smaller, but the largest diameter of the centering piece 25 is larger than the inside diameter of the winding tube 1.
  • the preferably provided spherical connection between the hub 21 and the centering piece 25 can also align the centering piece accordingly. Therefore, wobble errors and out-of-roundness errors are avoided. Misalignment of the centering plate 2, 3 (Fig. 5) are compensated for by the self-aligning ball bearing 20.
  • the pin 16 is cantilevered in a hole.
  • the pin has a thread and a collar 18 at its free end.
  • the pin is firmly clamped in the hole by means of screw 17.
  • a ball bearing 20 is fixed axially.
  • the ball bearing 20 has an outer ring with a spherical outer contour.
  • the cylindrical hub 21 of the centering plate 2 is seated on the outer ring.
  • the inner contour of the cylindrical hub 21 is also spherical. It is surrounded by an annular recess 31 and, if necessary, has one or more axially parallel incisions. As a result, the hub 21 can be elastically expanded and pushed over the outer ring of the ball bearing 20.
  • the centering plate 2 also has a cylindrical shoulder 32. On its outer circumference, the shoulder 32 has a circumferential groove 33 in a normal plane. A spring ring 34 is inserted into the circumferential groove 33 in such a way that the spring ring protrudes from the groove.
  • the centering piece 25 is annular. It has a corresponding groove on its inner circumference. With this groove 35, the centering piece 25 is mounted on the spring ring 34.
  • the spring ring can be, for example, a rubber ring with a rectangular or circular cross section, but also a metal ring in the manner of a plate spring. The difference in diameter between the inner circumference of the centering piece and the outer circumference of the extension is drawn here in an exaggerated manner.
  • the centering piece 25 has a conical outer circumference.
  • the largest diameter of the conical outer circumference is larger than the inner circumference of the winding tube 1.
  • the smallest outer circumference of the centering piece 25 is smaller than the inner circumference of the winding tube 1.
  • annular stop piece 26 is also axially projecting.
  • the inner circumference of the stop piece 26 is somewhat larger than the largest outer circumference of the centering piece 25 and smaller than the outer circumference of the winding tube 1.
  • the stop piece 26 thus forms with the cylindrical extension 32 an annular recess in which the centering piece 25 is mounted and is axially movable in this way, that it can partially dip into this recess.
  • the conical outer circumference of the centering piece first lies against the end face of the tube.
  • the centering piece 25 is axially displaced by the elastic mobility of the spring ring 34 into the recess between the stop piece 26 and the cylindrical extension 32 until the end face of the winding tube 1 also abuts the stop piece 26 of the centering plate 2.
  • the centering plate with the stop piece 26 is aligned precisely in the end face of the winding tube.
  • the winding tube is centered on the centering piece 25.
  • the cardanic mobility of the centering plate 2 on the ball bearing 20 also means that the centering plate can align with its axis of rotation on the axis of rotation of the opposite centering plate. This also compensates for misalignments.
