Definitions
- the present invention relates to a drafting system for a textile machine for drawing a strand-like fiber strand supplied to the drafting system.
- a textile machine which is preferably designed as an air-spinning machine.
- Draw frames for textile machines serve regardless of the type of textile machine to adjust the fineness of a strand-like fiber composite, for example, provided by a carding sliver or a plurality of parallel in the drafting fiber slivers to a desired value.
- the drafting system comprises a plurality of roller arrangements which are arranged one behind the other in a transport direction of the fed fiber composite and in turn each comprise two or more drafting rollers.
- draft rollers in the form of a roll and a counter roll are always present, with the roll being movable back and forth between a loading position and a discharge position. While in the load position, the roller body of the roller and the corresponding counter-roller are pressed against each other to clamp the fiber structure, the roller can assume a position in the unloading position in which the roller body of the roller and the corresponding counter-roller do not touch. The roller can thus be removed a distance in the relief position of the backing roll, so that the roll body does not touch and a fiber structure between the roll and counter roll can be inserted or removed from there.
- Object of the present invention is therefore to propose a drafting system and a textile machine equipped therewith, which eliminate the mentioned disadvantage.
- the drafting arrangement for a textile machine for hiding a strand-like fiber bandage supplied to the drafting system is characterized in that it comprises at least two drafting unit modules arranged one after the other in a transport direction of the fiber bandage.
- the individual drafting module modules each comprise a roller and a counter roller corresponding to the roller (it being understood that several rollers or mating rollers may be present per drafting module), the roller and the mating roller each having a drafting module having a roller body rotatable about a rotation axis.
- the roll body is, for example, a cylindrical plastic body (which may have multiple layers) or a metal cylinder having a corrugated surface.
- one or more rollers and / or counter-rollers can be looped around with a strap, as they are already known in the prior art.
- the respective straps may be guided in addition to the guide on the corresponding roller or counter-roller with one or more additional guide elements.
- each drafting module module comprises a separate carrier on which the roller and the counter-roller are mounted.
- each drafting module module comprises a separate carrier on which the roller and the counter-roller are mounted.
- the drafting system is divided into several drafting modules, each comprising a separate carrier, with only the roller (s) and counter-roller (s) of this drafting module are mounted on each carrier.
- the storage takes place here via the axes of rotation of the respective drafting rollers, which are rotatably mounted, for example, in ball or roller bearings of the carrier.
- the roller of a drafting module is mounted on a receiving such on the carrier of the respective drafting module, that it is movable independently of the rollers of the other drafting module between a load position and a relief position back and forth.
- the roller or rollers of a drafting module can thus be lifted independently of the or the rollers of the other drafting module from its or their corresponding counter-rollers.
- the roller bodies of the roller and of the corresponding counter roller are thus pressed against one another in the load position in order to clamp the fiber structure. to lead. Further, they can be moved away from each other in the rest position, so that they do not touch.
- the individual drafting system modules are thus independent of one another, so that the force flow between the roller and counter-roller within a drafting module is independent of the corresponding power flow within the remaining drafting system modules. If the roller of a drafting module is then pressed in its load position against the corresponding counter-roller with the aid of a loading element described in more detail below, then the guide of the fiber composite is independent of the guide in the other drafting system modules due to the separation of the drafting system into individual drafting system modules. Also, the loading force acting on the individual rollers of the drafting module can be adjusted individually for each drafting module, since the loading and / or movement of the roller of a drafting module in no way on the load and / or movement of the roller of the other drafting modules effect.
- the drafting system is, of course, in connection with one or more drives in a state installed in a textile machine in order to enable the above-mentioned distortion of the fiber strand.
- the drafting arrangement comprises a guide rail on which the carrier of at least one drafting module can be fixed with the aid of a fixing arrangement.
- the carrier is thus guided on a guide rail and is movable in a release position of the fixing arrangement relative to the guide rail, preferably linearly displaceable.
- the direction of movement should in this case be possible in one direction (and preferably only in this direction), which corresponds to the predetermined transport direction of the fiber composite within the drafting system.
- the mutual distance between two adjacent drafting system modules can be set in a simple manner by displacing one or both drafting system modules, the distance generally having to be set as a function of the fiber bundle to be distorted (the spacing must always be at least the length of the longest fibers of the fiber composite match to make sure the fibers at a certain point in time, only ever be clamped by the drafting rollers of a drafting module; otherwise the fibers would be torn between two drafting modules).
- the fixing arrangement can be transferred to a fixing position in which the corresponding drafting module is fixed relative to the guide rail.
- the fixing arrangement can be any means with which the respective drafting module can be fixed in place on the guide rail.
- at least one screw or a fixing bolt are used per fixing arrangement.
- the guide rail may have one or more depressions, in which engage one or more extensions of the respective drafting system modules (or vice versa).
- the extensions and / or the depressions may have one or more undercuts and, for example, be formed like a dovetail, so that the drafting module modules can be displaced exclusively relative to the guide rail, but can not be pivoted.
- the mutual position of all associated with the guide rail drafting module is fixed except for the mutual distance.
- the recesses and extensions are formed such that the drafting module modules connected to the guide rail can be removed independently of the guide rail, preferably detachable upwardly, when the fixing arrangement is in its release position. Individual drafting module can be easily and quickly replaced in this way, without the other drafting system modules or the guide rail would have to be removed from the drafting system.
- the recesses and / or the extensions could in this case, for example, have a rectangular or square cross-section. Preferably, said sections have no undercut to allow said lifting.
- the drafting system comprises at least two drafting modules of identical design.
- all drafting modules are of similar construction, although the similarity does not necessarily have to relate to the roller bodies.
- the type and / or size of the individual drafting rollers may vary between the individual drafting system modules.
- the roller and / or the counter-roller has an axis of rotation which is mounted only on one side in or on the carrier.
- the roller bodies are in this case laterally of the respective carrier, so that the fiber structure does not come into contact with the carriers.
- the individual axes of rotation should be mounted in pivot bearings of the carrier.
- the axes of rotation extend from the respective roller body through the carrier and protrude from the carrier on the side of the carrier facing away from the roller body.
- a drive means for. As a drive belt or a gear, attack, to enable the respective drafting roller in a rotational movement.
- the carrier of a drafting module comprises a first carrier section and a second carrier section, ie the carrier is in two areas is divided.
- the roller (or rollers) of the corresponding drafting module are in this case supported on the so-called first carrier section and the counter-roller (s) of the drafting module on the so-called second carrier section, wherein the first carrier section and the second carrier section are present as separate components.
- the two support sections may be the same or different. In any case, it is possible to adjust the position of the first support portion relative to the second support portion and thus the relative position of the roller to the counter roll.
- the roller in the predetermined transport direction of the fiber composite slightly before, slightly behind or just above the counter roll the adjustment affects the default result or is to choose depending on the fiber association.
- the first support portion and the second support portion of a drafting module are directly connected or in direct contact with each other.
- the first carrier section has a guide for mounting the second carrier section on the first carrier section and / or that the second carrier section has a guide for mounting the first carrier section on the second carrier section.
- the respective guide is oriented such that the carrier sections of a drafting module are displaceable relative to each other only in the direction of said transport direction. A movement in the axial direction of the axes of rotation, however, should be prevented by the guide.
- first carrier section can be fixed relative to the second carrier section and / or the second carrier section can be fixed relative to the first carrier section with the aid of at least one fixing element.
- the fixing element can be a screw or screw-nut combination, a lock or another means with which the relative position of the first to second support section can be fixed. If the fixing element (of which there can of course also be several per drafting module) is loosened, then NEN, the first and the second support portion relative to each other moves, preferably exclusively shifted, in order to adjust the position of the drafting rollers to each other.
- the at least one fixing element between a fixing position and a release position is movable back and forth, wherein the first support portion and the second support portion are movable relative to each other when the at least one fixing element is in its release position, and wherein the first Carrier portion relative to the second support portion and / or the second support portion relative to the first support portion is fixed by means of at least one fixing element when the at least one fixing element is in its fixing position.
- first carrier section and the second carrier section are in mutual contact both in the loading position and in the unloading position of the roller mounted on the first carrier section.
- first support portion relative to the second support portion in the relief position the same position as in the load position.
- the mutual position of the first and second support portion of a drafting module remains the same, as long as the fixing or fixing means are in their fixing position.
- the first and the second carrier portion form a C-shape in a side view of the drafting system.
- At least one drafting module comprises a loading element which is associated with the roller of the drafting module, and with the aid of which said roller in the loading position with a defined loading force can be acted upon.
- the loading element is preferably fastened to the support section on which the roller is also mounted.
- the loading element does not act directly on the axis of rotation of the roller. Rather, the loading element should be in contact with the receptacle in which the axis of rotation is mounted, in order to access the receptacle. to be able to exert a force.
- the loading element may be, for example, a pneumatic cylinder, an air spring or a bar cylinder.
- At least one loading element comprises (or comprise) a movably mounted pressure element, wherein the pressure element is formed by an elastic pressure membrane or is in communication with an elastic pressure membrane, the pressure membrane defining a pressure space , which is for example acted upon by means of a compressed air source with a pressure.
- the pressure membrane is preferably a flat or arched and elastic structure (eg made of a rubber or a rubber mixture). If the pressure chamber, which may be partially bounded by the pressure membrane and partially by a corresponding housing, subjected to a pressure, so the pressure membrane bulges outward, or tries to buckle accordingly (the pressure by introducing compressed air into the Pressure chamber can be generated).
- the loading of the rollers is thus primarily with the aid of compressed air, which can be provided by a compressed air network of the respective spinning or a compressor of the drafting textile machine.
- compressed air which can be provided by a compressed air network of the respective spinning or a compressor of the drafting textile machine.
- the advantage of using a corresponding membrane lies in the fact that in the pressure-related movement no static friction must be overcome because no mutually rubbing components are present. Rather, only the shape of the membrane must be changed to load a roller, which is done for example by introducing compressed air into the pressure chamber.
- the loading force or a change in the loading force is in this case accurately, reproducibly and without jerky load changes possible.
- Swivel lever is formed.
- the pivot lever has a U-shape.
- the pivot lever may in this case be mounted on the support via the two limbs of the U-shape, wherein the axis of rotation should be supported in the region of the base of the U-shape connecting the limbs (the base preferably has a bore for this purpose, in which there is a pivot bearing in which the axis of rotation of the roller is mounted).

- the spindle has an internal discharge channel, through which the yarn is removable from the vortex chamber.
- the textile machine which is preferably designed as an air-spinning machine, thus serves to produce a yarn from an elongate fiber structure.
- the outer fibers of the fiber composite are wound around the inner core fibers by means of a vortex air flow generated by the air nozzles within the vortex chamber in the region of the inlet opening of the yarn formation element and thereby form the binder fibers which determine the desired strength of the yarn.
- the term yarn generally means a fiber structure in which at least some of the fibers are wound around an inner core.
- a yarn is included in the traditional sense, which can be processed into a fabric, for example with the aid of a weaving machine.
