Definitions

  • the invention relates to a device for crimping synthetic thread bundles or tapes according to the preamble of claim 1.
  • the rotary drive for the Thrust washer comprises a second piston-cylinder unit, which are structurally separate from the first piston-cylinder unit housed in a recess in the side wall of the stuffer box is.
  • the associated piston rod is approximately tangential aligned with the thrust washer and at its free end provided with a pivotable pawl, which is in a toothing the thrust washer engages. The back and forth This causes the piston to move in a gradual rotation Thrust washer converted.
  • the thrust washer can be rotated with one mounted shaft journal on which a gear sits. This meshes with a second gear, which apparently belongs to a rotary drive not mentioned in detail. Instead of the gear transmission, a belt or Chain gear can be used. There is also manual rotation possible. With a hydraulic or pneumatic clamping device, whose piston rod is aligned with the shaft journal and acts on its free end, the thrust washer pressed against the end faces of the rollers.
  • DE-OS 42 29 989 describes a so-called “rotary linear Unit”, which is designed as a compact unit, an output rod protrudes from the front. This stands inside the housing with both a piston and cylinder Unit trained linear actuator as well a pressure medium powered swing vane motor in drive connection.
  • the output rod can therefore be independent a lifting movement and a reciprocating movement from each other Execute swivel movement, the swivel movement on an angular range is limited, which results from the geometry of the swing wing motor results and for example 272 Degrees.
  • DE-OS 32 12 636 shows several other pressure medium-operated Units where swivel motors are different Design with a linear drive to a compact Assembly are summarized. All versions have in common that a single peg-shaped output member both axial honking movements as well as reciprocating Executes swiveling movements.
  • the invention has for its object a device to create with the features of the generic term at those used to press and turn the thrust washers Organize itself through simple, compact structure, high reliability and distinguish low costs.
  • This task is characterized by the characteristics of the Claim 1 solved.
  • a particular advantage of the invention is that the required components from specialized manufacturers as standard manufactured and delivered ready for installation.
  • Figure 1 shows in perspective a device according to the invention.
  • Figure 2 shows a partial view from the side.
  • Figure 3 shows a part in section.
  • FIG. 4 shows a section along line IV-IV in FIG. 3.
  • Figure 5 shows another for another embodiment Section analogous to Figure 3.
  • Figure 6 shows a for another embodiment Section analogous to Figure 3.
  • Figure 7 shows one for the embodiment of Figure 6 Section analogous to Figure 4.
  • a stuffer box can be seen through side plates 1, 2, a base plate 3 and a cover plate 4 is limited.
  • the bottom plate 3 is with the side plates 1, 2 firmly connected.
  • the cover plate 4 is through a Force symbolized by an arrow 5, pivotable about a horizontal axis.
  • two rollers 6, 7 are arranged through a motor, not shown, in the arrows 8, 9 indicated direction of rotation can be driven.
  • the end faces the rollers 6, 7 extend up to the side plates 1, 2.
  • the axes of the rollers 6, 7 are horizontal and parallel spaced from each other such that between the rollers 6, 7 have a narrow gap through which the bundle of threads to be treated is pressed into the stuffer box becomes.
  • the area around the nip is at both End faces of the rollers 6, 7 by a circular thrust washer 10 covered, which fits in a recess of Side plates 1, 2 are seated.
  • a rotary clamping device designed as an assembly 11 and below is described in detail, the thrust washer 10 is on the end faces of the rollers 6, 7 can be pressed and in the symbolized by the arrow 12 sense rotated gradually.
  • the axis of rotation of the thrust washer 10 is parallel to the Axes of the rollers 6, 7 aligned.
  • eccentricity e has a horizontal and a vertical Component.
  • the assembly 11 consists of three fixed interconnected parts 15, 16, 17. These are modular put together to form a columnar aggregate, which with a flange 18 in a horizontal position the side plate 1 is attached.
  • Part 15 is a swing motor.
  • Figure 4 shows in a cylindrical cavity 19 with a vertical cylinder axis two pistons 20, 21 housed by a Rack 22 are interconnected. This combs with a pinion 23, which rotatably on one to the pressure plate 10 coaxial swivel shaft 24 sits. At both ends of the cylindrical cavity 19 openings 25, 26 are provided. There are not shown lines for feeding and discharge of a pressure medium connected, for example Air or oil. By alternately applying the Pressure medium, the rack 22 is moved back and forth.
  • the Swivel shaft 24 is in a limited angular range and panned here. The size of the angular range depends on the length of the rack. At a length that is a little is larger than the diameter of the pinion 23, the Swivel range approximately 120 degrees.
  • Part 16 is a tensioning element. It has a cylindrical one Cavity 27, in which a piston 28 is housed has a coaxial bore. The bore is telescopic the pivot shaft 24 slidably guided. It stretches through part 16 into the interior of part 17. At both ends of the cylindrical cavity 27 are connection bores 29, 30 for feeding and discharging a Pressure medium provided. By alternately loading the piston 28 is axially back and forth with a pressure medium movable. The sliding fit on the swivel shaft 24 enables Relative movements both in the axial direction and in Circumferential direction.
  • the part 17 has a cylindrical housing 31 consisting of a relatively narrow section 31 a, which is attached to the flange 18 connects, and an expanded section 31 b, the the part 16 is screwed tight.
  • a rod 32 housed by a positive Clutch disc 33 is connected in a rotationally fixed manner to the pressure disc 10 is.
  • Rigidly connected to the rod 32 is one thick-walled, pot-shaped sleeve 34, which in the expanded Section 31 b is housed.
  • the rod 32 and the Sleeve 34 together form an output member whose shape reminds a chalice.
  • In the interior of the sleeve 34 protrudes Swivel shaft 24 into it.
  • a Freewheel 35 installed in an annulus between the Swivel shaft 24 and the inner surface of the sleeve 34 so that an axial relative movement between sleeve 34 and pivot shaft 24 is possible.
  • the Swing motor 15 forms one together with the freewheel 35 Rotary drive, which is an intermittent, gradual rotation the pressure plate 10 allows.
  • an axial bearing 36 Thrust bearing 36 is between the end face of the piston 28 projecting into the part 17 and the end face the sleeve 34 and that from the sleeve 34 and the rod 32nd existing output member, the piston 28 is axially against the Thrust washer 10 can be clamped so that it is on the end faces the rollers 6, 7 are pressed.

  • the parts form 15, 16 a sub-group 40, a single, in the part 17 protruding output pin 41.
  • the piston of the tensioning member 16 as a common output pin 41 educated.
  • a recess 42 of the driven pin 41 protrudes a pivot shaft 43, which with the pinion 23 of the Swing motor 15 forms a rigid unit.
  • Between the Swivel shaft 43 and the output pin 41 is -z. B. due to a cross-section deviating from the circular shape Recess 42 and the positively engaging therein Swivel shaft 43- a non-rotatable connection, which is a sliding Axial movement of the output pin 41 relative to Swivel shaft 43 allowed.
  • the output pin 41 has one coaxial end piece 41 a with a reduced diameter. With an annular shoulder that marks the transition to the tail 41 a forms, the output pin 41 is supported against Thrust bearing 36. The end piece 41 a protrudes into the sleeve 34. In the annular space between the end piece 41 a and A freewheel 35 is installed on the inner surface of the sleeve 34.
  • FIG. 6 and Figure 7 differs from the exemplary embodiment according to Figure 3 and Figure 4 essentially in that the Swivel motor 15 and the clamping member 16 not by one Pressure medium, but are operated electrically.
  • spools 44, 45 connected to a power source, not shown are on a rack 46 of the swing motor 15 and a lifting force is exerted on a piston 47. Since otherwise in accordance with the embodiment according to Figure 3 and Figure 4 is a further description dispensable.
