Definitions
- the invention relates to a device for compressing a fiber structure on a spinning machine, comprising a support, which has a receptacle for a bolt, with a rotatably mounted suction drum, which has a closed and an open end side and arranged in the region of the closed end side of a bearing element is, via which the suction drum is rotatably mounted on an end portion of the bolt, wherein the bolt protrudes from the open end side of the suction drum.
- WO 2012068692 A1 describes a device for compacting a fiber material on a spinning machine, which is intended for subsequent attachment to a conventional drafting device of a spinning machine.
- the device is arranged downstream of the drafting unit of the spinning machine and serves to compact (compact) a fiber material discharged from the drafting unit.
- the compacted fiber material after passing through a nip, is fed to a swirl-generating device.
- the swirl-generating device consists of z. Example, in a ring spinning machine from a rotor which rotates on a ring, wherein the yarn produced is wound on a rotating sleeve.
- the compacting device described in WO 2012068692 A1 has for use on the usual twin drafting of ring spinning machines on two suction, driven and circulating suction drums, which are axially parallel and spaced from each other via a bearing element rotatably mounted on a shaft mounted on a support ,
- the carrier has a receptacle for the rotationally fixed mounting of the shaft.
- a sleeve-like locking element is described in WO 2014027234, which is in each case pushed onto the end portion of the shaft or the shaft journal. This means that two suction drums are assigned as a unit (module) to a twin drafting system.
- the carrier has a suction channel connected to a vacuum source, which is connected to the interior of the suction drums via corresponding inserts.
- the Inserts are provided with correspondingly shaped suction slots, whereby a corresponding air flow is generated at the periphery of the respective suction drum in a compression region.
- the suction drums are each assigned an annular drive element in the form of a friction wheel, which rests under the action of a compressive load with its circular inner surface partially on the circular peripheral surface of a arranged on the end face of the respective suction drum approach.
- the rotational movement of the driven over the outer circumference friction wheel is transmitted via friction on the peripheral surface of the neck, which is connected to the suction drum.
- the friction wheel in turn is driven by a frictional engagement of the driven lower output roller of the drafting system.
- the friction wheel is held in position in the axial direction on the projection by a closing cap fastened at the end of the projection, an axial gap being formed between the closed end face of the suction drum and the friction wheel.
- the suction drum is deducted by the operator together with the pressed-bearing element from the shaft journal, cleaned outside the device and plugged back onto the shaft journal.
- a major disadvantage is that after frequent assembly or disassembly of the suction drum frictional grating forms on the outer surface of the shaft journal and the inner surface of the bearing element. A simple and quick assembly or disassembly of the suction drum is thus no longer ensured with increasing running time of the device. This has a negative effect on the maintenance of the spinning machine.
- the invention is therefore the object of an apparatus for compressing a sliver on a spinning machine with a suction drum form such that a simple and fast assembly and disassembly of the suction drum during the entire period of the device is possible.
- the inventive compression device may be permanently installed following the respective drafting of a spinning machine, or be provided for retrofitting to a conventional drafting device.
- a bolt is to be understood as meaning a short shaft which has a round cross section.
- the bolt can also be designed as a n-sided profile. The object is achieved in that the suction drum is axially fixed as seen in the axial direction over the bearing element with the bolt and at least one fastening means is provided, via which the bolt is releasably secured in the receptacle.
- the bolt is firmly integrated into the assembly consisting of suction drum and bearing element, so that the suction drum and the bolt together form a separate unit of the device Fixing the suction drum and bolt simply prevents the suction drum from being separated from the bolt. mel is removed as the entire unit with the bolt, ie there is no removal of the suction drum from the bolt.
- the main advantage of the axial fixation is that the formation of friction at the junction between the bolt and bearing element is avoided. This has a positive effect on the assembly and disassembly of the suction drum and the maintenance of the spinning machine.
- the at least one fastening means may be integrated in the carrier or constitute a separate component on the carrier.
- a screw is fastened to the carrier, which secures the bolt in its operating position in the receptacle in the axial direction.
- the bolt has a radial bore into which a locking pin attached to the carrier projects into the operating position and secures the bolt in the receptacle in the axial direction.
- a roller bearing which comprises an outer ring, an inner ring and rolling elements.
- the suction drum is rotatably connected at its closed end face to the outer ring and the end portion of the bolt with the inner ring of the bearing, for example via a press fit.
- the suction drum is rotatably mounted on the bolt.
- This type of fixed connection has the advantage of easy assembly of the separate unit.
- the rolling bearing comprises only one outer ring and rolling elements.
- the suction drum is rotatably connected to the outer ring and is rotatably supported on the rolling elements on the end portion of the bolt.
- the rolling elements for example bearing balls, are in direct contact with the surface of the bolt.
- the bolt is therefore made of a hardened steel or of ceramic, or has a surface coating.
- the bolt and the rolling bearing form a subassembly of the separate unit. This further simplifies assembly of the separate unit since the subassembly can be mounted to the vacuum drum in a single assembly step.
- the fastening means is designed as a locking element which can be flexibly deflected in the radial direction.
- ren partial section is provided and the bolt between its two end portions has a circumferential recess, wherein the flexibly deflectable portion projecting in the operating position in the circumferential recess of the bolt and secures the bolt in the axial direction on the carrier.
- the diameter of the bolt decreases towards the recess at an angle of between 25 ° and 60 ° with respect to the central axis of the bolt
- the diameter of the bolt at the end of the bolt is at an angle of between 25 ° and 60 ° to the central axis of the bolt This prevents the bolt from running into the receptacle when it is inserted into the receptacle and becoming blocked
- the proposed flexibly deflectable portion is displaced in the radial direction by the bolt Diameter of the bolt is greater than the clear diameter the recording at the location of flexibly evasive section.
- the flexibly deflectable section Due to the radial displacement of the flexibly deflectable portion of the bolt can be easily transferred to its end position (locking position). In the end position, the flexibly deflectable section can again elastically expand into the circumferential recess of the bolt, ie, in the end position, the flexibly deflectable section returns due to its elasticity back to its original radial shape and is securely held in the recess of the bolt.
- the locking element and the recess act together as a kind of snap connection, by means of which the suction drum can be easily mounted or dismounted on the device. At the same time a good axial securing of the suction drum on the support of the device is ensured by means of the snap connection.
- the carrier has a plurality of locking elements which engage in the circumferential recess of the bolt.
- the receptacle is designed as a sleeve, which is arranged rotationally fixed in the carrier and has the flexibly deflectable portion. This makes it possible to provide the carrier with a simple bore into which the sleeve is inserted.
- the rotationally fixed arrangement of the sleeve in the carrier takes place, for example, via a type of shaft hub connection, wherein the carrier has an elevation and the sleeve has a depression on its outer circumference into which the elevation protrudes.
- the flexibly deflectable partial section in the radial direction extends over a part of the circumference of the sleeve and protrudes in its rest position into the cavity of the sleeve, so that at this point the clear diameter of the sleeve is smaller than the diameter of the bolt.
- the sleeve is advantageously made of a plastic which has good elastic properties.
- the flexibly deflectable part section consists of at least one tongue-shaped section, which is located in
- the inner surface of the tongue-shaped portion whose free end projects into the circumferential recess at least partially in the radial direction at an angle between 10 ° and 25 ° with respect to the central axis of the bolt. This ensures that the tongue-shaped portion during the displacement (assembly) of the bolt can move completely into the region of the recess of the bolt.

- the bolt 36 also has peripheral grooves 47 on its surface, in which unwind the rolling elements 44.
- the carrier 16 has a separate sleeve 48 for receiving the bolt 36.
- the sleeve 48 is non-rotatably arranged in the carrier 16 via a kind of shaft hub connection, wherein the carrier 16 has an elevation 52 and the sleeve 48 on its outer periphery a recess 51 ( Figure 5), in which the elevation 52 protrudes.
- the sleeve 48 has a locking element 50 with a radially deflectable part portion 50 in the radial direction.
- the flexibly deflectable partial section 50 has an arcuate section 50 which is formed over part of the circumference of the sleeve 48.
- the tongue-shaped portion 50 is displaced by the bolt 36 in the radial direction.
- the reason for this is that the diameter DB of the bolt 36 is greater than the clear diameter LD of the sleeve 48 ( Figure 5) at the location of the tongue-shaped portion 50.
- the tongue-shaped section 50 can again elastically expand into the circumferential recess 53 of the bolt 36, ie in the end position the tongue-shaped section 50 returns. Because of its elasticity back to its original radial shape and is securely held in the recess 53 of the bolt 36.
- the diameter DB of the bolt 36 decreases toward the recess 53 at an angle a between 25 ° to 60 ° with respect to the central axis A1 of the bolt 36. As a result, a good axial securing of the bolt 36 in the sleeve 48 is ensured. So that during assembly, the bolt 36 can be safely moved over the tongue-shaped portion 50 in its end position, the diameter DB of the bolt 36 tapers at the end projecting from the suction drum 14 at an angle b between 25 ° to 60 ° with respect to the central axis A1 of the bolt 36. This prevents the bolt 36 from entering and being blocked on the tongue-shaped portion 50 when it is inserted into the sleeve 48.
- the free end 49 of the tongue-shaped portion 50 points in the direction of the Saugtrom- mel 14.
- the inner surface of the tongue-shaped portion 50, the free end 49 projects into the circumferential recess 53 at least partially in the radial direction, extends at an angle c between 10 ° and 25 ° with respect to the central axis A1 of the bolt 36. This ensures that the tongue-shaped portion 50 during the displacement (assembly) of the bolt 36 can move completely into the region of the recess 53 of the bolt 36.
- the locking element 50 and the recess 53 cooperate like a kind of snap connection, by means of which the separate unit of suction drum 14 and bolt 36 can be easily mounted or removed on the support 16 of the device VM. At the same time a good axial securing of the separate unit on the support 16 of the device VM is ensured by means of the snap connection.
- a closing cap 21 is fastened, which with its outside diameter projects beyond the clear width of the friction wheel 20.
- the end cap 21 is provided with an annular projection 40, which in the inside width of the annular projection 13 of the suction drum 14th protrudes.
- FIG. 5 shows a side view Z of the sleeve 48 according to FIG. 4.
- the sleeve 48 has on its outer circumference a depression 51, into which the elevation 52 of the carrier 16 protrudes.
- the flexibly deflectable in the radial direction portion 50 which is formed as a tongue-shaped portion protrudes in its rest position into the cavity 54 of the sleeve 48 into it.
- the clear diameter LD is established in the sleeve 48 at the location of the tongue-shaped portion 50.
- the tongue-shaped portion 50 can smoothly dodge in the radial direction, so that the clear diameter LD increases when the bolt 36 is moved with its diameter DB on the tongue-shaped portion 50 during assembly.
- the inner surface 55 of the tongue-shaped portion 50 is provided with a radius, which favors the insertion of the bolt 36 in the sleeve 48 and facilitates. As soon as the indentation 53 of the bolt 36 (FIG. 4) is completely in the axial direction at the level of the tongue-shaped section 50, the elastic diameter of the tongue-shaped section (spring action) reduces the clear diameter LD, as a result of which the tongue-shaped section 50 is displaced into the recess 53 of the bolt 36.
