Definitions

  • the present invention relates to an opening roller for an open-end spinning device with a base body which is releasably connected by means of a rotary closure with a clothing carrier, wherein the clothing carrier for connecting to the base body relative to this about a rotational axis from an unlocked position into an engaged position and from this further into a endlagige Locking position is rotatable.
  • Object of the present invention is therefore to provide an opening roller with a secure screw cap, so that it is avoided that the clothing carrier dissolves during operation of the body.
  • the opening roller for an open-end spinning device has a main body and a clothing carrier.
  • the main body and the clothing carrier are releasably connected to each other by means of a rotary closure.
  • the rotary closure is preferably a quick release, by means of the fast and easy assembly and disassembly of the clothing carrier is ensured on the body.
  • the two bodies in the engaged position in the circumferential direction of the opening roller are still loosely connected to each other, so that they can be rotated relative to each other with respect to the axis of rotation.
  • the coupling of the clothing carrier with the main body is preferably formed in the engaged position such that a first distinction of the clothing carrier engages in a second decision of the base body form-fitting manner that they are positively connected to each other in the axial direction of the opening roller.
  • the clothing carrier Only in the locked position, in contrast to the engagement position not only in the axial direction, but in addition in the circumferential direction of the opening roller, a coupling between the clothing carrier and the body before.
  • the locked position the clothing carrier is securely locked relative to the base body, so that the clothing carrier can not become detached from the base body during operation.
  • the rotary closure comprises at least one securing element. This prevents the clothing carrier moves during operation relative to the main body of the engagement position in the unlocked position. This is particularly advantageous if the clothing carrier has not been properly rotated in the locking position when connecting to the body. Furthermore, it is also conceivable that a properly locked clothing carrier moves from the locking position into the engaged position, if, for example, parts of the rotary closure - the effect of which is to keep the clothing carrier relative to the main body in the locked position - due to wear or damage for this not are more capable. Advantageously, it can thus be avoided by means of the securing element that the clothing carrier is completely released from the base body during operation.
  • the securing element between a securing position and a passage position is movable.
  • the securing element prevents a rotation of the clothing carrier from the engagement position into the unlocked position.
  • the securing element allows for mounting a rotation of the clothing carrier from the unlocked position into the engaged position and for disassembly of the engaged position in the unlocked position.
  • the securing element is arranged on the base body.
  • the repair costs of the opening roller can be reduced because the clothing carrier is subject to greater wear compared to the main body.
  • the securing element is retained even with frequent replacement of the clothing carrier.
  • the securing element is designed such that it moves from the securing position into the passage position moved in the axial direction of the opening roller at least partially in the direction of the base body.
  • the assembly and disassembly of the clothing carrier can be facilitated on the body.
  • the clothing carrier must first be placed on the base body and then pressed against it, wherein the securing element moves in the axial direction of the opening roller from the securing position into the passage position.
  • the movement of the securing element takes place as a pivoting or sliding movement.
  • the securing element has to be moved manually from the passage position back into the securing position. In this case, it may happen that the clothing carrier is unsecured relative to the base body, if previously forgotten by the operator, to move the fuse element back into the securing position. Because of this, it is advantageous if the securing element is designed such that it automatically returns to a deflection into the passage position, in particular during assembly and / or disassembly of the clothing carrier on the main body, back into the securing position.
  • a self-locking securing element which automatically returns to the securing position, can be structurally simple and inexpensive realized by the fuse element is resilient.
  • the securing element can be designed completely as a spring element or else have only individual resilient regions or components.
  • the resiliently formed securing element is designed such that it is spring-loaded in a deflection in the passage position in the direction of the securing position and / or spring-loaded in the securing position.
  • the securing element is designed as a spring or as a resilient securing element, there is a risk that during assembly or disassembly of the clothing carrier, the securing element or parts thereof are plastically deformed, namely, when the mounting force applied by the user exceeds the plastic deformation threshold.
  • the resiliently formed securing element has at least one overload stop against which it strikes, in particular when deflecting into the passage position, before it plastically deforms.
  • the securing element is designed as a securing spring leg.
  • This preferably has a base, a free end and a bending area formed between these two.
  • the free end and / or at least partially the bending region are formed pivotable or deflectable about the base, in particular in the axial direction of the opening roller, between the securing position and the passage position.
  • the securing spring leg in particular in the region of the bending region and / or the free end, has a run-up slope, which is inclined relative to the base by an angle ⁇ , in particular in the direction of the base body.
  • a connecting element of the clothing carrier can slide on a displacement of the engagement position in the unlocked position along the ramp, so that the clothing carrier relative to the main body is movable into the unlocked position.
  • the execution area is inclined relative to the base by an angle ⁇ , in particular in the direction of the base body, wherein the angle ⁇ is preferably smaller than the angle ⁇ .
  • the free end of the securing spring leg is arranged in the circumferential direction of the opening roller adjacent to the base of the locking spring leg. In this way it can be ensured that the clothing carrier, in particular its connecting element, abuts against the free end of the securing element when the clothing carrier has not previously been properly locked in the locking position.
  • the clothing carrier is provided for an opening roller rotatably mounted about an axis of rotation of an open-end spinning device. It has parts of a quick release, by means of which the clothing carrier is detachably fastened to a base body of the opening roller.
  • the quick release is designed as a rotary closure, so that the clothing carrier is releasably connectable to the base body by means of a rotary movement about the axis of rotation, which takes place relative to the base body provided therefor. This ensures a very quick and easy assembly and disassembly of the clothing carrier on / from the base body of the opening roller.
  • secure fastening of the clothing carrier to the base body is ensured by the rotary closure, in particular acting axially on the connection Forces can not cause a detachment of the clothing carrier from the body.
  • the clothing carrier has at least one second abutment surface, which with a second abutment surface of the base body is able to correspond such that between the clothing carrier and the base body in the axial direction a positive connection is formed.
  • the two second stop surfaces are not adjacent to each other, but have a game to each other when the clothing carrier for connecting to the body relative to this, in particular against the direction of rotation, is rotated.
  • the second stop surfaces act as overload protection for the spring element, if the clothing carrier erroneously wants to be removed by means of an axial movement of the body.
  • the first abutment surface is arranged on the clothing carrier in such a way that it points in the axial direction. As a result, the second stop surfaces can absorb very high forces without the clothing carrier slipping relative to the base body.
  • the first abutment surface can be produced in a particularly simple and cost-effective manner if it is formed on the connecting element, in particular as a shoulder. In addition, this allows a particularly space-saving design of the rotary closure, since at the same time an overlap region between the second stop surfaces can be formed.
  • a compact design can be realized when the locking edge is formed on the connecting element spaced from the first edge in the circumferential direction, in particular in the region of a second edge of the connecting element. Furthermore, thus the two stop surfaces corresponding to each other only come into contact with the latching edge when the latching shoulder engages.
  • the shoulder and the locking edge are preferably located on the two opposite flanks of the connecting element.
  • the clothing carrier has a spring element which is able to correspond with a connecting element arranged on the main body.
  • the depression has the advantage that the fitting ring can only be connected to the base body when it is oriented correctly with respect to this with a clothing carrier formed in two parts with a clothing holder and fitting ring. Furthermore, a secure entrainment of the fitting ring in the direction of rotation is ensured by means of the thus formed positive connection between the base body and ring. Slipping of Garniturrings is thus excluded.
  • the rotary closure allows easy and quick assembly and disassembly of the clothing carrier, whereby maintenance and repair times for replacement of wearing parts, in particular the clothing wearer, are greatly reduced.
  • the clothing carrier is connected in the axial direction positively to the base body.
  • the connection between the clothing carrier and the base body can absorb very high forces in the axial direction, whereby a secure anchoring of the clothing carrier is ensured in the body.
  • the clothing carrier in the circumferential direction is positively and / or non-positively connected to the base body. An unintentional detachment of the clothing carrier from the base body can be avoided in particular if it is connected in a form-fitting manner with the base body counter to the direction of rotation of the opening roller.
  • the base body and / or the clothing carrier have a spring element, in particular a leaf spring.
  • the spring element can also be designed as any other previously known spring.
  • the spring element is arranged on the base body and / or on the clothing carrier in such a way that it presses the base body and the clothing carrier against each other, in particular when engaging in the connecting element, in the axial direction. As a result, a frictional connection is formed between the base body and the clothing carrier in the circumferential direction.
  • the contact pressure of the spring element is so great that the connection does not dissolve on the one hand when braking the opening roller and it can be solved at the same time on the other side by the muscle power of the average person.
  • a very quick and easy assembly and disassembly of the clothing carrier from the body is guaranteed at the same time high separation safety.
  • by pressing together a substantially backlash-free connection between the clothing carrier and the base body in the dissolution region, in particular in the region of the clothing, is ensured. As a result, no fibers can accumulate here, which would lead to unevenness and / or impurities in the yarn by continuous accumulation and subsequent detachment.
  • the main body and the clothing carrier each have at least one first and / or one second stop surface.
  • the first stop surface is arranged on the base body and clothing carrier such that they rest against each other when the clothing carrier for connection to the base body relative to the base body, in particular against the direction of rotation, is twisted.
  • a positive connection of the clothing carrier is advantageously formed in the circumferential direction with the body, whereby the rotary closure, in particular counter to the direction of rotation of the opening roller, high forces is able to act, in particular when starting the opening roller and when dissolving the sliver act on the rotary closure.
  • the spring element has at least one resilient leg with a free end and in the region of the free end a latching shoulder is formed, which is latched to a latching edge of the base body and / or the clothing carrier.
  • the locking shoulder of the fitter advantageously receives an acoustic and haptic feedback, so that he knows exactly when the clothing is relative to the body in the correct angular position in which a reliable locking of the clothing carrier is ensured in the body.
  • the interlocking locking shoulder and locking edge in the circumferential direction form a positive connection and / or adhesion, whereby unintentional release of the rotary closure, in particular during braking of the opening roller, is prevented.
  • the latching edge on the connecting element is spaced from the first flank in the circumferential direction, in particular in the region of a second flank of the corresponding with the spring element Connecting element formed.
  • the locking shoulder of the spring element engages only behind the locking edge, when the first abutment surfaces for positive connection in the circumferential direction abut each other.
  • the rotary closure comprises a positioning aid, by means of which the two bodies can be positioned relative to one another in the unlocked position for mounting the two bodies. Finding the correct one Mounting position, which corresponds to the unlocked position, this is much easier. At the same time damage to the fuse element and parts of the rotary closure, in particular a locking spring leg, which may arise from improper installation, avoided. At the same time the handling of the opening roller is facilitated during assembly, since the correct mounting position can be found faster.
  • the locking element in particular the locking spring leg, or the securing element, in particular the securing spring leg, a preferably acting in the axial direction reinforcing element is associated.
  • a reinforcing element is assigned, since this can be protected in the engaged position befindlichem clothing carrier from improper disassembly in the axial direction.
  • such a reinforcing element can also protect the locking spring leg against improper mounting, for example when trying to mount the clothing carrier with axial pressure on the base body, without having previously positioned the two parts in their correct mounting position to each other. Wear or damage to the locking spring leg, which reduce the locking torque between the body and the clothing carrier, can be avoided.
  • the securing element is associated with a reinforcing element.
  • the main body 2 and the clothing carrier 3 are releasably connected to each other by means of a rotary closure 8.
  • the rotary closure 8 is as Quick lock formed. This allows a quick assembly and disassembly of the clothing carrier 3 done.
  • the rotary closure 8 is designed such that the clothing carrier 3 can be connected by means of a rotational movement counter to the direction of rotation R of the opening roller 1 relative to the base body 2 with this releasably.
