Description

Warp knitting machine for producing warp knitted fabric

Background

Warp knitting machines for producing warp knitted fabrics have been known for decades in many embodiments. Generally, in warp knitting machines a plurality of knitting tools are carried by a bar and driven via a bar carrier with a lever shaft extending in the machine width direction. The lever shaft is in most cases supported in the machine frame and comprises a plurality of intermediate walls which are arranged offset to one another in the machine width direction. Typically, the knitting tools used comprise crochet hooks, thread guide elements (such as for example eyelet needles or thread guide tubes), sliders and knitting sinkers (such as for example clip knockover sinkers, knockover comb sinkers or grip comb sinkers). The knitting tools are usually carried by guide bars, which are driven in the warp knitting machine by means of in each case one lever shaft in such a way that they execute, independently of one another, a pivoting movement in a plane transverse to the lever shafts, i.e. in a plane extending in the machine height direction and in the machine depth direction during operation. The guide bar carrying the thread guide elements, the heat-conducting thread guide bar and additionally being mounted and driven in such a way that it executes an oscillating offset movement in the machine width direction, which superimposes its oscillating movement. One each of the guide bar filled with the crochet hook, at least one guide bar filled with the knitting sinker and at least one guide bar filled with the thread guiding element are used for generating the knitting position of the warp knitting fabric in the functional connection with each other. Depending on the type of warp knitting fabric and warp knitting machine, additional guide bars and knitting tools may participate in this functional connection. Known embodiments of warp knitting machines are tricot machines in which the produced warp knitted fabric is pulled forward approximately in a horizontal direction by a fabric pulling device, and raschel machines in which the produced warp knitted fabric is pulled downward approximately vertically by a machine in a vertical direction by a fabric pulling device. Here, a pulling force acts on the warp knitted fabric, which has an influence on the properties of the produced warp knitted fabric.

DE10349417B3 describes a warp knitting machine for producing spaced knitwear, the guide bars of which can be set transversely to the machine width direction corresponding to the machine depth direction in the basic position. For this purpose, the thread guide bars are arranged on a carrier at the machine frame, which can be positioned in the machine depth direction by means of a central drive. In the case of a lowering or increasing of the spacing of the two resulting fabric tracks of the spaced knitting by moving the crochet hook in the machine depth direction, it should be possible for the thread guide bar position to be matched to the position of the crochet hook and for the thread guide element to co-act with the crochet hook without defects.

In DD120669 a device is described for changing the swinging movement of the guide bars of a warp knitting machine. The thread guide bar is connected to two lever shafts via two carriers, which are in turn driven by a drive tappet via a connection from a lever. The position at which the drive tappet is coupled to the lever can be varied by means of a screw structure with an elongated hole. In this way, both the amplitude and the speed of the oscillating movement carried out can be adapted simultaneously, wherein the course of the oscillating movement in three-dimensional space does not change. This is advantageous in particular in the case of varying the number of guide bars or the fineness of the machine, so that the maximum possible operating speed of the warp knitting machine can be set in each case. The thread guide bar is connected to the two lever shafts via a plurality of levers and a carrier, and thus does not perform a swinging movement about a fixed axis of rotation of the lever shafts but rather about a base point, which can be moved depending on the dynamics of the structure consisting of the levers and the carrier during the swinging movement.

The manufacture of warp knit fabrics with a different diversity of compositions, i.e. warp knit fabrics comprising, for example, different combinations of yarn material, different numbers of yarns per stitch, different stitch formations and/or different combinations of stitch formations, may require the use of different numbers of guide bars or another warp knitting machine, such as a raschel warp knitting machine, instead of a tricot warp knitting machine.

It is known to date to produce warp knitted fabrics not only with four warp knitting fabrics (which require four guide bars) but also with less than four guide bars in different batches on tricot machines with four guide bars. With the number of guide bars, however, the optimum pivoting movement of the thread guiding element relative to the crochet hook and the optimum pivoting movement of the crochet hook also vary in order to ensure as rapid, efficient and error-free formation of the loops as possible. The pivoting movement of the latch needle is designed here such that the latch needle performs an approximately vertical up-and-down movement during the warp knitting process. In this way, for example, in a warp knitting machine with four guide bars, the pivoting movement of both the thread guiding elements and the crochet is longer than in a warp knitting machine with two guide bars. If two warp-knitted fabrics are produced on a warp-knitting machine with four guide bars, the thread-guiding elements and the crochet hook must for this purpose pass a longer path in their oscillating movement than on a warp-knitting machine with only two guide bars, and the knitting speed is therefore slower. Likewise, a matching of the spatial course of the swing movement can be required, so that the weaving speed can be optimally matched to the number of thread guide bars used. Therefore, warp knitted fabrics, which require a different number of guide bars for their production, have hitherto usually been produced on different warp knitting machines at optimum knitting speeds. Furthermore, there are warp knitted fabrics which, due to their composition, are firstly produced on the basis of their combination of stitch bonding and stitch bonding, either only on raschel knitting machines or only on tricot knitting machines. For example, a pillar with a high share (i.e. with stitch binding, in which the yarn is inserted in sequence in a plurality of stitch rows into the same crochet hook and thus does not have a connection to adjacent stitch pieces) is not produced on a tricot machine and requires the use of a raschel machine.

Disclosure of Invention

The invention is therefore based on the object of specifying a warp knitting machine which makes it possible to produce batches of warp knitted fabric with different compositions continuously on a single warp knitting machine.

This object is achieved according to the invention by the preambles and the features of

claims

1 and 12. The relative position of the lever shaft with which at least one of the guide bars can be driven and the lever shaft with which at least one further guide bar can be driven can be adjusted in the machine height and/or machine depth direction of the warp knitting machine. To vary the diversity of the composition of the fabric track of the manufacture of the warp knit fabric, the relative position can be varied in the machine height and/or machine depth direction.

In this way, the course of the oscillating movement of the thread guiding element can be matched with respect to the knitting movement of the crochet hook in the case of increasing the number of thread guiding bars. For example, in machines with four guide bars, the oscillating movement of the thread-guiding element and the crochet hook can be optimally coordinated with the number of guide bars. If the textile is to be produced in the same machine at this time, which requires the use of two guide bars, the swinging movement of the thread-guiding element and the crochet cannot be optimally coordinated with a reduced number of guide bars on previous machines; the crochet hook can, for example, perform a short swing movement in a warp knitting machine with only two guide bars, which increases the knitting speed. By adjusting the relative position of the lever axis of the thread guide bar in the machine height and/or machine depth direction, the pivoting movement of the thread guide element can be adapted to the changing pivoting movement of the crochet hook. Furthermore, for example in the case of changing a warp knitting machine from a tricot knitting machine to a raschel knitting machine, the relative position of the lever axes driving the guide bars can be adjusted in such a way that the pivoting movement of the thread guiding elements extends as far as possible in the machine depth direction at the level of the bearded needles, whereas the pivoting movement of the thread guiding elements has a relatively large directional component in the machine height and machine depth direction with respect to its value in the tricot knitting machine at the level of the bearded needles.

It is possible to use the teaching according to the invention in all types of warp knitting machines. However, it is advantageous to use the teaching according to the invention on warp knitting machines which are suitable only for producing a single fabric layer (for example raschel machines without double segments or warp knitting machines which are suitable for producing spacer fabrics with two fabric layers). Usually, such machines have only a lever shaft, which is in a weaving connection with the guide bar, which carries the crochet hook, for which torque is thus transmitted. The bar carrying the crochet is also referred to below as the needle mount (nadelberre). Advantageously, the different guide bars of such a machine work together to produce one fabric layer. In a double-segment raschel knitting machine, two fabric layers and a spacer knit with these two fabric layers are produced opposite one another. The plurality of fabric tracks produced simultaneously side by side in the machine width direction on the warp knitting machine thus corresponds to a fabric layer, when all the crochet hooks involved in the knitting process are driven by the lever shaft about the same axis of rotation.

This has the additional advantage that the angular range of the pivoting movement of the lever shaft, with which the at least one thread guide bar is driven, can be adjusted. The angular range of the pivoting movement is used to initially adapt the position and length of the pivoting movement to a circle with a fixed pivoting radius about the axis of rotation of the lever shaft. It is therefore advantageous, in particular in the case of a change in the number of guide bars, to match the angular range of the pivoting movement. It is also advantageous if the angular range of the pivoting movement is adapted in the case of a change from tricot knitting to raschel knitting (or vice versa) in such a way that the pivoting movement extends in the raschel-knitted fabric as far as possible in the machine depth direction at the level of the latch hooks, whereas in contrast the pivoting movement has comparable direction components in the machine height and in the machine depth direction at the level of the latch hooks in the tricot knitting machine. In any case, it is possible that such an adjustment is also carried out with the drive means, for example by switching on one or more gears. The same applies when the "thread guide shafts" are not associated with individual drives, but rather the required torques originate, for example, from a central drive or drives for at least two shafts. Likewise, the lever shafts associated with the other guide bars may advantageously undergo a change in the angular range of their swinging movement. In connection with all embodiments of the invention, it is advantageously allowed that at least two drivers are provided. An additional effect is that one of the drives is associated with the at least one thread guide bar. Another drive can advantageously drive the remaining guide bars. The remaining guide bars may however also be associated with a plurality of drives, for example one drive per guide bar. As a further object, it is advantageous to provide a control device for a plurality of lever shaft drives, which control device is designed to control the drives.

Particularly advantageous are warp knitting machines with a machine frame which carries a lever shaft and comprises an upper machine part and a lower machine part, wherein the upper machine part and the lower machine part are adjustable relative to one another in the machine height direction and/or in the machine depth direction. Advantageously, the machine upper part comprises at least the lever shaft of the thread guide bar and the components drivable thereby. For example, the lever shaft of the thread guide bar can be rotatably received by the machine upper part about its axis of rotation. In an advantageous embodiment, the lever shaft of the thread guide bar is implemented rotatably about its axis of rotation by means of a support, wherein the upper machine part accommodates the support, which comprises at least two bearings.

An advantageous embodiment of the invention is a warp knitting machine whose upper machine part comprises at least two upper intermediate walls which are offset parallel to one another in the machine width direction and whose lower machine part comprises at least two lower intermediate walls which are offset parallel to one another in the machine width direction. Advantageously, the upper intermediate wall and the lower intermediate wall comprise bearings, wherein at least two bearings of different intermediate walls form at least one support for the at least one lever shaft. It is furthermore advantageous if in each case one upper intermediate wall is connected to in each case one lower intermediate wall in such a way that the relative position of the intermediate walls with respect to one another can be set. For example, each upper intermediate wall can be connected to each lower intermediate wall by a screw structure, wherein the screw structure comprises at least one threaded and/or mating threaded fastener, at least one through-bore or slot and at least one threaded bore. In place of a mating threaded fastener, a screw arrangement with a threaded fastener, which is in functional connection with at least one mating pin, is likewise advantageous. In this way, advantages with regard to production costs and housing costs are achieved for the manufacturer of such warp knitting machines, since the machine which is variable in this way makes the construction of a large number of variants unnecessary and likewise requires fewer different types of components, in order to be able to produce different types of warp knitting machines.

Advantageous are warp knitting machines which comprise means for setting the relative position between parts of the machine frame, such as an upper machine part and a lower machine part. A particularly advantageous means for setting the relative position is a spacer plate, which is arranged between parts of the machine frame. The thickness of the spacer plate extending in the machine height direction determines the relative position between the parts of the machine frame in the machine height direction. It is also advantageous if at least two spacer plates are arranged one above the other between the parts of the machine frame in order to adjust the relative position between the parts of the machine frame by the sum of the thicknesses of the at least two spacer plates. It is thus possible to set a greater spacing between the upper and lower machine parts by combining at least two existing spacer plates, without the need for a spacer plate of another thickness. Another advantageous means for setting the relative position between the upper and lower machine parts is a screw structure comprising at least one threaded fastener, at least one elongated hole, the longitudinal axis of which extends in the machine depth direction, and at least one threaded bore. For example, the lower machine part may comprise the at least one threaded bore and the upper machine part and the spacer plate comprise for each threaded bore at least one long hole each. By moving the upper machine part in the direction of the longitudinal axis of the slot, i.e. in the machine depth direction, it is thus possible to set the relative position of the upper machine part and the lower machine part in the machine depth direction. It is particularly advantageous if the upper machine part and/or the lower machine part comprise dimensions in the machine height and/or machine depth direction, which enable an accurate and repeatable settable relative position. Another advantageous means for setting the relative position between the upper and lower machine parts is a rail connection. A form-fitting rail connection is advantageous. Particularly advantageous are rail connections which enable adjustability in the machine depth direction and/or the machine height direction and are free of play in the machine width direction. It is also advantageous if the rail connection comprises means for locking the relative position between the upper and lower machine parts. Also advantageous are warp knitting machines which comprise at least one electric motor which drives the machine upper part in its adjusting movement in the machine height and/or machine depth direction.

An advantageous embodiment of the invention is a warp knitting machine whose machine upper part comprises at least one deflection drive which drives the at least one thread guide bar in its oscillating deflection movement in the machine width direction. The advantage here is that no adjustment of the relative position between the upper machine part and the lower machine part is therefore necessary, as is the connection between the at least one offset drive and the at least one guide bar, since the position of the at least one offset drive relative to the at least one guide bar does not change. The preparation time for adjusting the relative position between the upper machine part and the lower machine part can thereby be reduced.

Advantageously, the lever shafts are associated with in each case one swivel drive for their respective swivel movement, wherein the swivel drives preferably comprise an electric motor. The pivot drive serves to drive the lever shaft into a rotational movement about its rotational axis. When each lever shaft is associated with its own pivot drive, the costly central drive, which connects all lever shafts to a central drive motor, can be omitted. The construction and maintenance costs and complexity of the warp knitting machine are reduced.

It is furthermore advantageous if the at least one wobble drive comprises a linear stepping motor. It is particularly advantageous if a crank drive connects the output shaft of the linear stepping motor to one of the lever shafts, wherein the crank drive comprises a drive lever and a joint, which is eccentrically connected to the lever shaft. The crank mechanism converts the linear drive movement into a rotational movement of the lever shaft about its axis of rotation. The great advantage of the crank mechanism is that the drive movement can be transmitted as free as possible even when changing the direction of movement, and thus without loss of the motion portion.

It is also advantageous if the at least one wobble drive comprises a rotary stepping motor. It is particularly advantageous if the winding gear connects the rotary stepping motor output shaft to one of the lever shafts. For example, the lever shaft can be driven by a rotary stepping motor by means of a toothed belt, wherein toothed belt disks are arranged on the rotary stepping motor output shaft and the lever shaft, which disks are connected to the toothed belt in a form-fitting manner. By means of the form-fitting connection, the drive movement is transmitted without slipping and thus without loss of the movement portion.

An advantageous embodiment of the invention is a warp knitting machine, the upper machine part of which comprises at least one pivoting drive for the lever shaft of the at least one guide bar. In this way, a setting of the relative position between the upper machine part and the lower machine part can be achieved without a matching of the connection between the swing drive and the lever axis of the at least one guide bar, since the position of the at least one swing drive relative to the lever axis of the at least one guide bar does not change. In this way, the preparation time for the adjustment of the relative position between the upper machine part and the lower machine part is reduced. For example, the toothed belt must be replaced relative to a toothed belt with a corresponding matching length each time the relative position between the upper machine part and the lower machine part is adjusted when the pendulum drive is connected to the lever shaft by means of the toothed belt, when the pendulum drive is not accommodated by the upper machine part.

Furthermore, a warp knitting machine is advantageous, the plurality of pivoting drives of which comprise an electric motor. These motors can advantageously be operated by means of an electronic control device. The electronic control device may comprise means for generating and enhancing signals, a storage device and power electronics. Typically, it is a machine computer that provides control signals. Which operates the frequency converter in the case of a normal electric machine or suitable power electronics, such as a booster circuit (motor driver) suitable for operating a stepping motor. Finally, the motor is loaded with a current, voltage, frequency or signal for a matching motion profile (wegungsprodile). In this way, the electronic control device controls the drive movement of the motor, wherein the warp knitting machine converts the drive movement of the motor into a knitting movement of the knitting tool and the knitting tool is thereby driven by the motor.

The electronic control device is advantageously designed to control the electric motor in such a way that it drives the knitting tool driven by it in accordance with a defined, predetermined movement profile. Particularly advantageous is a motion profile which is programmable. It is furthermore advantageous to combine the motion profiles into groups, wherein each group comprises one motion profile for each knitting tool of the warp knitting machine and the motion profiles are coordinated with one another in such a way that the knitting tools perform knitting motions matched to one another during their time segments. The presetting of the movement profile enables a targeted control of the knitting movement of the knitting tool as a result. In the case of an adjustment of the relative position of the upper machine part and the lower machine part, the knitting movement of the thread guiding element can thus be newly coordinated with the relative position of the other knitting tool and the knitting movement, for example, and the warp knitting machine can set more variably the batch for producing warp knitted fabrics with a different diversity of components.

In order to continuously produce batches of warp knitted fabric with different compositions, it is advantageous to have a method in which at least two different oscillating drives are used, the movement of which first drives at least the thread guide bar and second drives at least the other bar and the two oscillating drives being controlled in such a way that the thread guide elements of the thread guide bar and the needles of the other bar perform a knitting movement which is coordinated with one another. By using at least two different swing drives, it is possible to actuate the swing movements of the different guide bars independently of one another and thus to coordinate the weaving movements of the guide bars with one another. The knitting movements of the knitting tools can thus be coordinated with one another more variably when the relative position of the lever shaft driving the thread guide bars has to be changed due to changing the batch of warp knitted fabric.

It is particularly advantageous if the actuation of at least two pivoting drives is carried out on the basis of a stored motion profile, which is individually coordinated with the components of the respective batch. Each motion profile here represents a specific weaving motion of the weaving tool. Advantageously, the movement profile is preset as an input variable during the preparation of the warp knitting machine and is selected and programmed in accordance with the warp knitting fabric to be produced.

The movement profiles of the knitting tools must be coordinated with one another in such a way, depending on the selected composition of the warp knit to be produced, that the knitting tools interact synchronously in order to produce the desired warp knit. In order to generate a warp knit of a specific composition, a set of motion profiles coordinated with one another is thus present, which comprises exactly one motion profile for each knitting tool. Advantageously, at least two sets of movement profiles coordinated with one another are stored in the storage device and used according to the selected composition of the warp knit being produced. In this way, a matching movement profile can be selected when preparing the warp knitting machine and does not have to be reprogrammed.

Advantageous are warp knitting machines which comprise knitting sinkers (also referred to below simply as sinkers) for stitch formation, which are suitable for producing not only raschel fabrics but also tricot machine fabrics in general. Such a sinker is described later. Advantageous is a sinker for a warp knitting machine with a knockover edge, a grip edge and a knockover edge, wherein the knockover edge extends in the width direction and at least in sections in the longitudinal direction of the sinker and the height direction of the sinker is directed vertically upwards from the surface of the knockover edge, the grip edge is arranged opposite the knockover edge in the height direction at a distance therefrom and the knockover edge delimits and connects the knockover edge and the grip edge rearwards in the longitudinal direction, wherein at a transition point of the knockover edge a resting edge adjoins the knockover edge and at a transition point of the support edge a support edge adjoins the resting edge, wherein the support edge extends at least in sections approximately in the longitudinal direction and is arranged in the height direction below the knockover edge. Preferably, the support edge extends forward in the longitudinal direction starting from the support edge transition point and/or only forward in the longitudinal direction starting from the support edge transition point. Particularly advantageous are sinkers in which the support edge transition point is at least four times as far in height direction from the knockover edge transition point as in longitudinal direction. Advantageously, the knockover edge is of straight configuration and the knockover edge extends entirely in the longitudinal direction. The knockover edge can however also extend in a curved manner, so that the knockover edge extends in the longitudinal direction only in sections, possibly even only in infinitely small sections. The longitudinal direction can then be determined by a tangent line, which is arranged at the knockover edge midway between the point of transition of the knockover edge and the point ending forward via its grip edge. The width direction, the longitudinal direction and the height direction of the sinker jointly form a rectangular coordinate system which is fixed at the position of the sinker; it can also be moved together with the possible movements of the sinkers relative to a previously introduced coordinate system of the warp knitting machine, including the machine depth direction, the machine height direction and the machine width direction, and in particular can also be twisted about the axis in the machine width direction. In all operating states of the warp knitting machine and the sinker, the width direction of the sinker however corresponds to the machine width direction.

Sinkers with knockover, gripping and knockover edges are typically used in tricot machines. By means of the additional arrangement of the correspondingly embodied abutment edge and support edge adjacent to the knockover edge, the sinker is set up for knocking over by the (pillar) stitch when the pulling device of the warp knitting machine pulls in the vertical direction. Thus, a warp knit fabric produced only on a raschel knitting machine can also be produced using sinkers. The conversion of tricot to raschel fabrics can be done even without replacing the knitting tools (such as sinkers, for example but also needles).

The sinker can advantageously be punched from a steel strip as is customary. The thickness direction of the steel strip is then the width direction of the sinker. The sinker can be designed to be moved longitudinally relative to the knockover edge for stitch formation, as is usual for sinkers with knockover edge, gripping edge and knockover edge. The support edge may be arranged parallel to the knockover edge. The support edge may however also be arranged at an angle of between 0 ° and 25 ° with respect to the knockover edge. Preferably, the theoretical point of intersection between the supporting edge and the knockover edge is then in front of the sinker in the longitudinal direction. The angle between the abutment edge and the support edge is preferably 90 °. The support edge can thus support a knockover band, which has a advantageously rectangular cross section. Furthermore, the so-supported knockover band can be brought into abutment against the abutment edge, so that it is pressed against the abutment edge by a pulling force acting on the warp knit. The pulling force may act downward in the warp knitting machine in its vertical direction. The spacing of the support edge transition point from the knockover edge transition point, which is at least four times greater in the height direction than in the longitudinal direction, results in the abutting edges of the sinkers or the outer faces of the sinker segments being arranged approximately in the vertical direction of the machine in the machine. The abutment edge or the outer face can be inclined by up to 25 ° or, for example, 15 °,10 ° or 5 ° with respect to the vertical direction of the machine in such a way that the abutment edge or the region of the outer face lying further below projects further forward in the horizontal direction than the region lying further above in the vertical direction. In the following, vertical pulling is therefore also understood as a pulling direction which deviates from the vertical at the mentioned angle. The support edge may extend forward in the longitudinal direction from the support edge transition point. The support edge can extend forward or only forward in the longitudinal direction relative to the section of the abutment edge adjacent to the transition point of the knockover edge. The support edge transition point can be arranged further forward in the longitudinal direction with respect to an imaginary line extending the section of the abutment edge adjoining the knockover edge transition point or with respect to the section of the abutment edge adjoining the knockover edge transition point. In this way, for example, a knockover band can be supported on the support edge, which is pressed against the support edge and against the abutment edge by the pulling force of the warp knitting fabric. The sinker may have a surface coating. The sinker may have a foot. The sinker may be implemented without a foot. The sinker may be set up to move substantially parallel to its longitudinal direction. In this connection, the sinker can extend significantly further in its longitudinal direction than in its height direction. The gripping edge can run parallel to the knockover edge. At the transition point of the support edge, the contact edge transitions into the support edge at a break angle or at an angle, wherein the angle of the envelope is preferably between 70 ° and 110 °. The sinker preferably comprises no means, which are inclined with respect to the guide in the ring comb of the circular weaving machine.

Advantageously, the support edge transition point is spaced apart from the knockover edge transition point by 3mm and 10mm in the height direction. The spacing may take any value therebetween, such as 5mm or 6.5 mm. Advantageously, the contact edge also comprises a retaining device which is designed as a recess and/or a bulge of the partial section of the contact edge. The holding device can have a section which runs perpendicular to the contact edge or at a small angle to a vertical line of the contact edge in order to be able to clamp or clip the knock-off strip. The holding device can likewise be embodied rectangularly with an angular rounding and/or undercut (Hinterschneidung) which is small in relation to the length of the side edges. A larger spacing between the support transition point and the knockover edge transition point can provide more structural space for mounting the retaining device at the abutting edge.

It is particularly advantageous if the support edge ends up to 2mm forward in the longitudinal direction by a support edge transition point. The support edge may have an extension of maximum 2mm in the longitudinal direction, for example 0.7mm or 1 mm. Any value up to 2mm is advantageous. The front end region of the support edge may be the element of the sinker that is furthest forward in the longitudinal direction away from the support edge transition point.

A further advantage is achieved in that the knockover edge and the abutting edge enclose an angle of between 90 ° and 115 °. Particularly advantageous is an angle between 95 ° and 110 °.

Advantageously, the knockover edge projects forward in the longitudinal direction beyond the grip edge by a maximum of 2 mm. In the case of coarse fineness (machine compartment) or large-mesh woven fabrics, the knockover edge can project beyond the grip edge by a maximum of 5mm forward in the longitudinal direction. Particularly advantageously, the knockover edge can project beyond the grip edge forward in the longitudinal direction by a value between 1mm and 5mm or by a value between 1.5mm and 4mm, for example 2mm, 2.5mm or 3 mm. A knockover edge extending only 2mm or less further forward than the gripping edge enables the drawing of the warp knit down in the vertical direction of the warp knitting machine without having to pass a large path through the sinker or sinker assembly for stitch formation.

An advantageous embodiment of the warp knitting machine according to the invention comprises a sinker assembly. The invention is based on the object of providing a sinker segment arrangement with a plurality of sinkers described above, which are arranged in a row at a constant distance in the width direction, and at least one circling band which rests against at least a partial number of the resting and supporting edges of the plurality of sinkers and bridges the distance between at least two sinkers in the width direction, and the outside of which lies opposite a face with which the circling band rests against the resting face of the sinkers. The sinker assembly is characterized in that the distance in the height direction between the upper end in the height direction of the outer face of the shedding belt and the lower end in the height direction of the outer face of the shedding belt is at least four times the distance in the longitudinal direction.

The knockover band can furthermore be used to knock over the chaining loops, which otherwise slip between the sinkers. By the position of the knockover band according to the height direction, the warp knitted fabric can be pulled and slid through the outer side of the knockover band approximately downward in the vertical direction of the warp knitting machine. A pulling direction horizontally forward in the machine direction is naturally also possible. In particular in the case of vertical pulling, the knockover band is pressed by the warp knit against the support edge and the abutment edge of the sinker. The knockover band can thus be connected to the sinker with sufficient reliability by means of a releasable fastening.

Advantageously, the knockdown band may have a substantially rectangular cross section which is substantially constant over its extension in the width direction. Such a belt can be cost-effectively created and repeatably assembled in the width direction over the entire extension of the sinker assembly. The width direction of the sinker corresponds to the width direction of the sinker assembly. The width direction of the sinker assembly is approximately the width over which a warp knit can be produced on a warp knitting machine. Warp knitting machines are generally between 1.28 and 7 meters wide, typically many meters, for example approximately 4 meters wide. The knock-out band may bridge the entire machine width. The knockover band may however likewise comprise a plurality of sections running in the width direction, which then in total extend over the entire width. Preferably, the sinker assembly comprises a plurality of partial assemblies of sinkers or modules with sinkers. The shedding belt can be made of a friction-resistant material, such as hardened steel, and/or provided with a friction-resistant coating. Preferably, the knockover band has a flat surface, advantageously with rounded edges, so that the quality of the rubbed warp knit is not affected.

Advantageously, the knockover band can be arranged flush or offset back in the height direction with respect to at least a partial number of knockover edges of the plurality of sinkers. This ensures that the warp knitted fabric can be pulled through the separating tape without problems during pulling.

The knockdown band may advantageously have at least one extension in the longitudinal direction, such as a support edge. Thus, the warp knit may not remain suspended at the transition to the support surface while sliding along the outer edge of the shedding bar. Particularly advantageous are support edges which are offset back in relation to the outer edge of the stripper belt.

Advantageously, the knock-out band can be fastened for its releasable fixation to at least a partial number of the plurality of sinkers in cooperation with at least one holding device of the abutting edge of at least a partial number of the plurality of sinkers. Advantageously, the knockover band can have a connecting means which is fastened to the knockover band and can be releasably fastened to the retaining device abutting the edge. The connector piece can be glued, for example, to the release tape. The connecting means can for example be clipped into the holding device against the edge. The connecting means can likewise be fixed at the release tape other than by gluing. The connecting means can also be integral with the knockover band. The connecting means may be a plastic profile. The connecting means can be clamped into a recess at the abutting edge of the sinker. The recess can have a cross section which at least partially corresponds to the cross section of the connecting means or can accommodate the section of the connecting means under stress. All known possibilities can be used with regard to the function of the releasable fastening.

Advantageously, the connecting means may have at least one spacer element which sets the spacing between the sinkers in the width direction at its front end. The sinker assembly can likewise be stabilized by connecting means. The one or more spacer elements may be the frequently occurring elevations of the connection device. Thus, a frame that ensures the homogeneity of the sinker assembly and that meets this purpose is unnecessary. However, it is also advantageous if the setting of the spacing of the front ends of the sinkers is effected via a frame, as is known. Such a frame may be suitable as known. The frame may then also pass through a hole in the sinker or a protrusion surrounding the sinker.

Also advantageous is a warp knitting machine according to the invention, which has at least the following features:

-at least one sinker assembly, the sinker assemblies being,

a coil forming region in which the coil is formed by knockover at a knockover edge or at a knockover band of the sinker assembly, and

a fabric pulling device for pulling the warp knit fabric from the loop forming area.

Furthermore, a warp knitting machine is advantageous, the fabric pulling device of which is configured in such a way that the warp knitted fabric can be pulled down substantially in the horizontal forward direction in at least one first predefinable setting and substantially in the vertical direction in at least one second predefinable setting. The direction oriented horizontally forward corresponds here as far as possible to the machine depth direction. The vertical direction corresponds to the machine height direction. The warp knit was pulled forward horizontally on a tricot machine. The warp knit is pulled vertically downward on a raschel machine. The loop-forming regions extend in a narrow band over the entire width of the warp knitting machine and have only a very limited extension in the vertical direction of the machine and in the horizontal direction towards the front or back of the machine. In known warp knitting machines, in which the knitting tools are driven via a central transmission (crankcase), stitch formation is possible only in a narrowly limited space. It is fixed by a movement flow preset by a central transmission mechanism.

Warp knitting machines can be used for producing warp knits and raschel knits by means of the design of the sinker segments and the general availability of the fabric-pulling device, for which purpose different knitting sinkers or sinker segments have to be purchased and equipped. Depending on the fabric-pulling device and the corresponding setting or switching of the relative positions of the mechanical components, completely different warp knitted fabrics can preferably be produced without replacement of the knitting tools.

The sinker units can move along an arcuate path (in the sense of an oscillating movement) as is usual in warp knitting machines. The arc-shaped track can be clamped in the horizontal direction before the warp knitting machine, namely the depth direction of the machine. The front is the direction from which the warp knitting machine is normally operated and along which the tricot machine is pulled. The longitudinal direction of the knockover edges and thus of the sinkers of the sinker assembly can be arranged at least partially parallel to the horizontal direction of the warp knitting machine during the formation of the loops. Preferably, the knocking-over edge is inclined forward by at most 10 ° at least at the time point of knocking-over the coil, when it is not parallel to the horizontal. The sinker assembly may also perform no movement during coil formation. The needle assembly can follow an arcuate track (in the sense of an oscillating movement) during coil formation as is usual in warp knitting machines. The curved track can encompass the vertical direction of the warp knitting machine, i.e. the machine height direction. A slightly longer needle shaft may be oriented at least approximately parallel to the vertical line at least in time during coil formation. The needle can deviate from the vertical orientation by a maximum of 10 ° and then preferably be tilted backwards with its hook. The needles are preferably less strongly inclined to the vertical than the outer edges of the knockover bands of the sinker assembly.

It is also advantageous if at least one first roller of the fabric-pulling device arranged next to the loop-forming area is drivable and reversible in its direction of rotation. Thereby, the pulling angle can be set as much as possible and the accessibility of the coil forming region is maintained.

Particularly advantageous are warp knitting machines in which at least one second roller of the fabric pulling device following the first roller is arrangeable in the vertical direction below the first roller in a first predefinable setting of the fabric pulling device and in the vertical direction on the first roller in a second predefinable setting of the fabric pulling device. Thereby, the setting or switching of the fabric-pulling device can be performed quickly. The necessary windings for the process of the fabric pulling force to be reliably brought in are present to a sufficient extent in both settings.

Detailed Description

Fig. 1 shows a schematic representation of a warp knitting machine 26, the machine frame 25 of which is divided into two parts and comprises an upper machine part 1 and a lower machine part 2, wherein the lower machine part 2 is arranged on a machine bed 14. The upper machine part 1 comprises a lever shaft 3 which is rotatably mounted in the upper machine part and is connected to a guide bar carrier 7. The thread guide bar 8 is supported on the guide bar carrier 7 so as to be movable in the machine width direction z. The support is not represented here for the sake of simplicity. The warp knitting machine 26 furthermore comprises three

further lever shafts

4,5,6, all three of which are rotatably mounted in the machine lower part 2 and guide the knitting movement into the knitting tool via the bar carrier and the bars. The bar carrier and the knitting tools are not represented. The upper machine part 1 and the lower machine part 2 are connected to each other by means of threaded fasteners 11, wherein the upper machine part 1 comprises for this purpose a long hole for each threaded fastener 11, the longitudinal axis of which extends in the machine depth direction x, and the lower machine part 2 comprises for each threaded fastener 11 a threaded bore hole. Other devices for connecting the machine upper part 1 to the machine lower part 2 are however also advantageously conceivable, for example a connection with a lockable rail. The upper machine part 1 can be moved in the machine depth direction x in this embodiment relative to the lower machine part 2 by a value corresponding to the length of the long hole. Between the upper machine part 1 and the lower machine part 2, a spacer plate 10 is arranged, with the height of which in the machine height direction y the relative position of the upper machine part 1 and the lower machine part 2 in the machine height direction y can be set.

Fig. 2 shows the warp knitting machine 26 from fig. 1 in a view rotated at 90 degrees about the machine height direction y. The machine lower part 2 comprises three lower intermediate walls 13, which are offset from each other in the machine width direction z and are connected to the machine tool 14. The upper machine part 1 comprises three upper intermediate walls 12; a lever shaft 3 with which the thread guide bar 8 can be driven; a swing drive 15 for the lever shaft 3; and an offset drive 16 for the guide bar 8. The three partition plates 10 and the machine upper part 1 are connected to the machine lower part 2 by means of threaded fasteners 11. The pivoting drive 15 drives the lever shaft 3, with which the thread guide bar 8 can be driven, and the thread guide bar 8 and the thread guide element 9 execute a pivoting movement about the axis of rotation of the lever shaft 3. At the same time, the offset drive 16 drives the thread guide bar 8 and the thread guide element 9 to an oscillating offset movement in the machine width direction z. By the superposition of the pivoting movement and the offset movement, the thread guiding element 9 executes a three-dimensional knitting movement.

Fig. 3 shows a section a, the position of which is presented in fig. 1. Three spacer plates 10 are present truncated. Two long holes 17, through which one threaded fastener 11 extends, are present in each of the partition plates 10. The elongated hole 17 of the spacer plate 10 enables adjustability of the relative position of the machine upper part 1 and the machine lower part 2 in the machine depth direction x.

Fig. 4 shows the pivot drive 15 of the

lever shafts

3,4,5,6, which comprises a linear stepper motor 18, a linear stepper motor output shaft 19, a drive lever 20 and a joint 21 mounted eccentrically at one of the

lever shafts

3,4,5, 6. The linear drive movement of the linear stepper motor output shaft 19 is converted into a rotational movement of the

lever shafts

3,4,5,6 via the drive lever 20 and the joints 21 eccentrically mounted on the

lever shafts

3,4,5, 6.

Fig. 5 shows the pivot drive 15 of the

lever shafts

3,4,5,6, which comprises a rotary stepping motor 22, a rotary stepping motor output shaft 23 and a winding gear 24. The winding gear 24 is preferably a toothed belt which is positively connected to the toothed belt disks on the rotary stepping motor output shaft 23 and the

lever shafts

3,4,5,6, wherein the rotational speed and the torque of the rotary stepping motor output shaft 23 are converted into the rotational speed and the torque of the

lever shafts

3,4,5,6 without slipping, depending on the number of teeth of the toothed belt disks.

All four

lever shafts

3,4,5,6 of the exemplary embodiment are associated with a pivot drive 15, wherein they can be controlled via a common electronic control device. The electronic control device comprises a memory device in which a movement profile for the knitting tool is stored and the knitting movement of the knitting tool is preset. To produce a warp knit fabric 120, all knitting tools must perform knitting motions that are coordinated with one another. Thus, the stored motion profiles are associated with groups, which comprise for each one knitting tool each one motion profile (which is coordinated with another motion profile in the group). The electronic control device can actuate the pivoting drive 15 in accordance with the selected group of motion profiles in such a way that the knitting tools execute knitting motions coordinated with one another. It is possible to correspondingly store different groups of movement profiles for warp knitted fabrics 120 with different diversity of components, which take into account the matching of the knitting movement of the knitting tool to the components of the warp knitted fabric 120. In this way, the correct knitting motion can be set by selecting the correct group of motion profiles in case of changing the composition of the warp knit 120.

Fig. 6 shows a schematic view of the spatial arrangement of the lever shaft 3 with respect to the thread guiding elements 9 and the crochet 27 when the warp knitting machine 26 operates according to the principle of a tricot machine. The illustration is not drawn to scale, in particular the swing radius 22 is represented too small with respect to the other elements of the illustration. The bar carrier 7 and the guide bars 8, which are not represented in fig. 6, are in the warp knitting machine 26 but connect the thread guiding elements 9 with the lever shaft 3. The thread guiding element 9 executes a pivoting movement 28 about the lever axis 3 on a circumference with a pivoting radius 33, which has a directional component not only in the machine depth direction x but also in the machine height direction y. By means of this oscillating movement 28, the yarn 30 is advanced to the crochet hook 27, wherein the yarn runs through the yarn guide opening 34 of the yarn guide element 9 and thus follows the oscillating movement 28. In order to obtain the desired course of the pivoting movement 28, a depth offset 31 in the machine depth direction x and a height offset 32 in the machine height direction y are present between the lever shaft 3 and the latch needle 27, which are coordinated with the knitting movement of all knitting tools.

Fig. 7 shows a schematic view of the spatial arrangement of the lever shaft 3 with respect to the thread guiding element 9 and the crochet hook 27 when the warp knitting machine 26 operates according to the raschel principle. The figure shows as much as possible the same elements as in fig. 6. The arrangement of the elements with respect to one another is however distinguished on the basis of the Raschel principle: the oscillating movement 29 of the thread guiding element 9 has a substantially smaller directional component in the machine height direction y than the oscillating movement 28 of a warp knitting machine operating according to the principle of the tricot machine. The pivoting movement 29 of the thread guiding element 9 extends in the raschel principle, therefore, mainly in the machine depth direction y. To obtain this course, the depth offset 31 between the lever shaft 3 and the latch needle 27 is substantially smaller than in warp knitting machines which operate according to the principle of tricot knitting machines, or the lever shaft 3 and the latch needle 27 are arranged one above the other in such a way that there is no depth offset 31 between the two. The height offset 32 must be greater in the Raschel principle than in warp knitting machines operating according to the principles of tricot machines, when the swing radius 33 is kept constant, so that the swinging movement 29 of the thread guiding elements over the height of the crochet hook 27 extends mainly in the machine depth direction x. In this case, the height offset 32 and the pivot radius 33 have approximately the same value in the raschel principle.

The warp knitting machine 26 described above, in which the lever shaft 3 with which the guide bar is driven is adjustable in its relative position to the

other lever shafts

4,5,6 and thus also to the knitting tools 27,101 of these

lever shafts

4,5,6 in the machine depth direction x and in the machine height direction y, can thus be operated not only according to the raschel principle but also according to the principle of a tricot machine by a correct setting of this relative position. This applies in particular when, in addition, the same fabric pull direction 121 and knitting sinkers 1 of the warp knitting machine 26 are suitable for this. Suitable woven sinkers 101, sinker assemblies 110 and fabric pulling devices 115 for this are described below.

Fig. 8 shows the front end portion of the sinker 101 in a view along the width direction B in a symbolized view. The sinker 101 comprises a knockover edge 102, which is of straight configuration and is inclined forwards (to the left in fig. 8). The grip edge 103 is disposed opposite the knockover edge 102 in the height direction H at a distance. The knockover edge 104 connects the knockover edge 102 and the grip edge 103 and restrains them rearward (right side in fig. 8). The knockover edge is bounded forward by a knockover edge transition point 105 to which a steeply descending abutment edge 106 running approximately in the height direction H adjoins. The abutment edge 106 has a recess in its lower region, which can serve as a retaining device 109. The abutment edge 106 ends downwards in a support edge transition point 107, to which a support edge 108 is coupled. Support edge 108 extends approximately parallel to knockover edge 102 and at a right angle to abutment edge 106. The sinker 101 is in the form of a section without its rear (on the right in fig. 8) for attachment to a further machine element, such as for example a guide bar. The connection of the sinker 101 to the further machine element can be designed arbitrarily according to the prior art.

Fig. 9 shows exemplarily in a symbolized view two sinkers 101 of a sinker assembly 110 with a knockover band 111 in a view from diagonally above and from the front. The sinker 101 is generally implemented the same as the sinker 101 of fig. 8. The release tape 111 rests on the support edge 108 and abuts against the abutment edge 106. The abutment edge 106 and the support edge 108 are correspondingly covered in this view by a release tape 111. The knock-out band 111 bridges in the width direction B between the sinker 101 and the warp knit, which can be pulled down in the height direction H as desired via the upper edge of the knock-out band 111 and its outer side 112. The drawing of the warp knit 120 can however also be carried out forward parallel to the longitudinal direction L parallel to the knockover edge 102. As in fig. 8, only the front end of the sinker 101 is presented. Fig. 9 shows only a part of the extension in the width direction B of the knock-out band 111 and the sinker assembly 110.

Fig. 10 symbolically shows an oblique view of a section of the knockover band 111 with the connecting means 113. The spacer element 114 embodied as a ridge of the connecting means 113 can be pushed in between the sinkers of the sinker assembly 110 and thus set precisely the required spacing thereof at its front end and stabilize it. According to fig. 9, two sinkers 101 can be spaced apart by the spacer elements 114 present.

Fig. 11 shows the fabric pulling device 115, the sinker segment 110 and the latch needle 27 of the warp knitting machine 26 in a symbolized view in the width direction B starting from the loop forming region in the direction Hz of the horizontal forward orientation of the warp knitting machine in the case of setting the fabric pulling device 115. Fig. 11 shows the sinker assembly 110 according to the prior art together with a slider needle assembly comprising a crochet hook 27 and a slider 123. The warp knit fabric 120, which is shown as a simple thread, is drawn approximately parallel to the knockover edge 102. The warp threads 30 (or likewise the threads 30) are fed in as usual substantially from above in the height direction, which in turn is symbolized by lines. The fabric-pulling device 115 is present in a first pre-settable setting 116. The first roller 118 of the fabric-pulling device 115 is rotated in a counterclockwise direction in this setting. The axis of the second roller 119 or the second roller 119 of the fabric pulling device 115 is arranged below the axis of the first roller 118 or the first roller 118 in the vertical direction V.

Fig. 12 shows the same components of the warp knitting machine in a symbolized view in the width direction B, but with the fabric pull direction 115 set in the vertical direction V. The fabric-pulling device 115 is present in a second pre-settable setting 117. The first roller 118 of the fabric-pulling device 115 is rotated in the clockwise direction in this setting. The second roller 119 of the fabric pulling device 115 is arranged above the first roller 118 in the vertical direction V. The warp knit 120 is pulled via the knock-out tape 111. The warp knit fabric 120 is pulled at a small angle with respect to the vertical direction V. The rollers 118,119 or their diameters are not presented in the same proportion as the braiding tool.

Fig. 13 shows a schematic view of a warp knitting machine 26 according to the invention in a configuration for producing a warp knit 120 in the sense of a tricot machine. The fabric pulling device 115 is located in a first predefinable setting 116, in which the resulting warp knit fabric 120 is pulled in the horizontal direction Hz as far as possible. The relative offset 31,32 between the lever shaft 3 and the latch needle 27 is set such that the thread guiding element 9 executes an oscillating movement 28 of the tricot machine, i.e. a movement over the height of the latch needle 27 as much as possible with similar directional components in the horizontal direction Hz and the vertical direction V. The resulting loops are unseated from the sinker assembly 110 by the crochet needle 27 through contact with the unseated edge 102.

Fig. 14 shows a schematic view of a warp knitting machine in a configuration for producing a warp knit fabric 120 in the sense of a raschel-knitting machine fabric. The fabric pulling device 115 is located in a second pre-settable setting 117, in which the resulting warp knit fabric 120 is pulled in the vertical direction V as much as possible. The relative offset 31,32 between the lever shaft and the latch is set such that the thread guiding element 9 executes a swinging movement 29 of the raschel machine, i.e. a movement in the horizontal direction Hz at the level of the latch 27 as far as possible. The resulting loops are unseated from the sinker assembly 110 by the barbed needles 27 by contact with the knockover strip 111 and the knockover edge 102. Where there is a decisive difference from the configuration from figure 13.
