Description

Sinker, sinker assembly and warp knitting machine

Background

Warp knitting machines (Kettenwirkmaschinen) are expensive investment goods. In order to produce different warp-knitted fabrics with different joining variants in knitting technology, first of all, when particularly different yarn stresses and yarn materials are likewise preset for warp-knitted fabrics or for knitted fabrics, different types of warp-knitting machines are used, which are known, for example, as tricot machines (kettenwirkhomomatrix) or raschel machines (raschel machines). Even when the machine types mentioned before have some similarities, no warp knitting machine has been known so far which can be used universally for the manufacture of all types of warp knitting fabrics. For example, the fabric pulling device is fixedly arranged at the warp knitting machine in the known warp knitting machine, so that the direction of the pulling of the warp knitting fabric is mainly only suitable for producing tricot or raschel fabrics. Also, the assembly of sinkers (sometimes also called slider) and sinkers is usually only set up for use in one type of warp knitting machine.

DE2643565C2 shows a sinker which is to be designed as a warp knitting machine with means for loop detachment and holding for tricot machines of the type. By means of a special design of the knockover edge with an adjacent falling front edge, the sinker should likewise be able to be used for producing knitted fabrics, which are furthermore produced on warp knitting machines of the type raschel knitting machine. The sinker presented should be used with an upstanding needle. This is however geometrically impossible with the presented sinker, since the correspondingly arranged needle collides with the rim of the sinker. Only if the needle can be combined with a particularly empty handle (with which the knitting process appears to be unpredictable) without collision with the sinker, the needle cannot transport the yarn past the nose of the sinker, since there is no room for this. In addition, the particularly mentioned chain stay is not possible because no transverse connection is disclosed between the knockover edges of the sinker, which enables functionally reliable knockover of the chain loops. The known rims are not usable for knockover. Thus, the characteristics of a functionally effective sinker are not directly and clearly known from this disclosure (together with, and in particular with, the accompanying drawings).

EP3276062A1 discloses a warp knitting machine of the tricot machine type, on which warp knitting fabrics ("tips") can be produced by means of specially moving sinkers and additional grips, which otherwise should only be able to be produced on a warp knitting machine of the raschel machine type. For this purpose, sinkers are used, which are typically used on tricot machines, in whose arrangement (at the bar) a loop-off device is additionally arranged. It is not possible to manufacture all warp knit fabrics universally, which can be manufactured on raschel knitting machines, because the fabric pulling is performed via horizontally arranged knockover equipment.

DE1174010 shows the fabric pulling of warp knitting machines in which the direction of rotation of the pulling roll pairs can be reversed. Different traction stresses should be set by changing the direction of idle. A certain change in the draw angle of the woven fabric is likewise obtained. But no mention is made of the further possibilities of the woven fabric to be manufactured, other than the manufacture of woven fabrics with different stresses.

DE4228048A1 shows a tricot machine on which it should be possible to produce reinforced fabrics, which are furthermore produced on raschel machines. For this purpose, the sinkers of the tricot machine are stationary and a continuous transverse carrier is arranged on the sinkers. The transverse carriers are fixed by means of wires, which are guided through holes in the sinkers, in which wires are furthermore arranged, which serve as a knockover element. A bleaching stabilizer which meets the standard and is transversely connected is arranged at the front end part of the sinker. For the reliable anchoring of such a stabilizer, the sinker often has a contour at the front end, which is completely surrounded by the stabilizer from above, from the front and from below. It should again be determined that only certain types of raschel fabrics (reinforcing fabrics with weft yarns and ground warp) can be produced on the tricot machine so modified.

Disclosure of Invention

Starting from this prior art, the object of the present invention is to specify a sinker, a sinker assembly and a warp knitting machine with which a versatile production of warp knitting fabric on a warp knitting machine can be achieved, so that it is not necessary to create different types of machines.

The sinker according to the invention for warp knitting machines has a knockover edge, a grip edge and a knockover edge. The knockover edge extends in the width direction of the sinker and at least in sections in the longitudinal direction. Advantageously, the knockover edge is of straight construction 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 just a partial section, possibly even only at an infinitely small section. The longitudinal direction can then be determined by a tangent line, which is disposed midway between the transition point of the knockover edge at the knockover edge and the point that ends forward via its gripping edge. The height direction of the sinker is directed vertically upwards from the surface of the knockover edge. The grip edge is arranged opposite to the knockover edge in the height direction at a spacing. The withdrawal rim is limited rearward in the longitudinal direction and connects the withdrawal rim with the grip rim. At the front end of the knockover edge, at the knockover edge transition point, the abutment edge is adjacent to the knockover edge. At the support edge transition point, the support edge is adjacent to the abutment edge. 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 from the support edge transition point and/or only forward in the longitudinal direction from the support edge transition point. The sinker according to the invention is characterized in that the distance of the support edge transition point from the knockover edge transition point in the height direction is at least four times the distance in the longitudinal direction.

Sinkers having a knockover edge, a gripping edge and a knockover edge are typically used in tricot machines. With the correspondingly embodied additional arrangement of the abutment edge and the support edge adjacent to the knockover edge, the sinker is set up for knockover from the (chain) stitch when the pulling device of the warp knitting machine pulls in the vertical direction. Thus, sinkers can also be used to create warp knit fabrics that are manufactured on Raschel knitting machines only. The conversion of tricot machine fabric into raschel fabric may be performed even without replacing knitting tools (such as sinkers, for example, but also needles).

The sinker according to the invention can be punched out of steel strip as in usual sinkers. The thickness direction of the steel strip is then the width direction of the sinkers. The sinker can be designed for movement longitudinally with respect to the knockover edge for coil formation, as is usual for sinkers with knockover, gripping and knockover edges. 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 deg. and 25 deg. with respect to the knockover edge. Preferably, the theoretical intersection point between the support edge and the knockover edge is then situated in front of the sinker in the longitudinal direction. The angle between the abutment edge and the support edge is preferably 90 °. The knockover strip can thus be supported on the support edge, which has an advantageously rectangular cross section. Furthermore, the loop strip supported in that way can be pressed against the abutment edge, so that it is pressed against the abutment edge by the pulling force acting on the warp-knitted fabric. The pulling force can act downwards in the warp knitting machine in its vertical direction. The distance between the support edge transition point and the knockover edge transition point, which is at least four times greater in the height direction than in the longitudinal direction, results in the abutment edge of the sinker or the outside of the sinker assembly being arranged approximately in the vertical direction of the machine in the machine. The abutment edge or the outer face can be inclined up to 25 ° or, for example, 15 °, 10 ° or 5 ° relative to the vertical direction of the machine in such a way that the abutment edge or the region lying further down on the outer face projects further forward in the horizontal direction than the region lying further up in the vertical direction. In the following, vertical pulling is thus likewise understood as a pulling direction which deviates from the vertical line by the mentioned angle. The support edge may extend forward in the longitudinal direction from the support edge transition point. The support edge may extend forward or only forward in the longitudinal direction relative to a section of the abutment edge adjacent to the trip edge transition point. The support edge transition point may be arranged further forward in the longitudinal direction with respect to a section of the abutment edge adjacent to the knockover edge transition point or with respect to an imaginary line extending the section of the abutment edge adjacent to the knockover edge transition point. In this way, for example, a loop strip 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-knitted 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 respect, the sinker can extend significantly further in its longitudinal direction than in its height direction. The gripping edge may extend parallel to the knockover edge. At the support edge transition point, the abutment edge transitions into the support edge at an angle of refraction or at an angle, wherein the angle of the inclusion is preferably between 70 ° and 110 °. The sinkers preferably do not comprise means which are inclined with respect to the guides in the ring combs of the circular weaving machine.

The support edge transition point may be spaced between 3mm and 10mm in height from the knockover edge transition point. The spacing may take any value in between, for example 5mm or 6.5mm. The abutment edge may comprise a retaining device, which may comprise a recess of at least one partial section and/or a ridge of the abutment edge. The holding device can have a section which runs perpendicular to the abutment edge or at a small angle relative to the vertical of the abutment edge in order to enable the clamping or clamping of the knockover band. The holding device can be embodied in this case likewise rectangular with corners with a smaller radius and/or undercut (Hinterschneidig) relative to the lateral length. The larger spacing between the support transition point and the knockover edge transition point may provide more structural space for mounting the holding device against the edge.

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

The knockover edge and the abutment edge may enclose an angle between 90 ° and 115 °. Particularly advantageously, the angle is between 95 ° and 110 °.

The knockover edge may protrude forward in the longitudinal direction by a maximum of 2mm beyond the gripping edge. In the case of coarse, fine (machine compartment) or large-meshed woven fabrics, the knockover edge may protrude forward in the longitudinal direction by a maximum of 5mm beyond the grip edge. Advantageously, the knockover edge may protrude forward in the longitudinal direction beyond the grip edge by a value between 1mm and 5mm or by a value between 1.5mm and 4mm, for example 2mm, 2.5mm or 3 mm. The knockover edge, which extends only 2mm or less further forward than the gripping edge, enables a pulling down of the warp knit in the vertical direction of the warp knitting machine without having to form a larger path through the sinker or sinker assembly for the loops.

A sinker assembly according to the present invention for a warp knitting machine has a plurality of sinkers according to claim 1, which are arranged in a uniform arrangement in a width direction at a constant pitch, and at least one knockover belt. The knockover belt rests against the support edge and at least a partial number of the rest edges of the plurality of sinkers. The knockover belt bridges the widthwise spacing between at least two of the sinkers. The outer face of the knockover belt is opposite the face with which it rests against the resting face of the sinker. The sinker assembly is characterized in that the distance in the height direction of the upper end portion in the height direction of the outer face of the knockover belt from the lower end portion in the height direction of the outer face of the knockover belt is at least four times the distance in the longitudinal direction.

The knockover belt can furthermore be used to knockover the chaining coil, which would otherwise slip between the sinkers. By the position of the knockover belt according to the height direction, the warp knit can be pulled to slide approximately downward in the vertical direction of the warp knitting machine past the outside of the knockover belt. A pulling direction horizontally forward in the machine direction is naturally also possible. Especially in the case of vertical traction, the knockover belt is pressed by the warp knitted fabric against the supporting edge and against the edge of the sinker. The knockover belt can thus be connected to the sinker with sufficient reliability by releasable fastening.

The knockover strip may have a substantially rectangular cross section, which may be substantially constant over its extension in the width direction. Such a belt can be created cost-effectively and reproducibly assembled widthwise 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 at which a warp knit fabric 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 knockover belt can bridge the entire machine width. The knockover belt can however likewise comprise sections 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 a module with sinkers. The knockover band may be composed of an anti-friction material such as hardened steel and/or provided with an anti-friction coating. Preferably, the knockover belt has a flat surface, advantageously with rounded edges, so that the rubbed warp knit is unaffected in terms of its quality.

The knockover belt may 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 past the ravel without problems during the pulling.

The knockover strip may have at least one extension in the longitudinal direction, such as a supporting edge. Thus, the warp knit fabric may not remain suspended at the transition to the support surface while sliding along the outer edge of the knockover belt. The support edge is offset back relative to the outer edge of the knockover belt.

The knockover belt can cooperate for its releasable fixation with at least one holding device of the abutment edge of at least a partial number of the plurality of sinkers. Advantageously, the knockover band can have a connecting means which is fixed at the knockover band, for example can be glued there. The connecting means may be releasably fixable at the holding device against the edge, e.g. grippable. The connecting means can likewise be secured at the knockover band other than by adhesive. The connecting means may also be in one piece with the knockover belt. The connecting means may be a plastic profile. The connecting means may be clamped into a recess of the sinker at the abutment edge. The recess may have a cross-section which corresponds at least in sections to the cross-section of the connecting means or which may accommodate the section of the connecting means under stress. With regard to the releasable securing function, all known feasibility schemes may be used.

The connecting means may have at least one spacing element which sets a spacing between the sinkers in the longitudinal direction at its front end in the width direction thereof. The sinker assembly can likewise be stabilized by the connecting means. The one or more spacer elements may be frequently occurring bumps of the connection means. Thus, a rim which ensures uniformity of the sinker assembly and satisfies the purpose is unnecessary. However, it is also advantageous if the setting of the spacing of the front ends of the sinkers is accomplished via a frame, as is known. Such a rim may be suitable as known. The frame may then also pass through holes in the sinker or around the projections of the sinker.

The warp knitting machine for manufacturing a general warp knitting fabric according to the present invention has at least the following features:

at least one of the sinker assemblies is provided with a plurality of sinkers,

a coil forming region in which the coil is formed by being knocked off at the knockover edge or at the knockover belt of the sinker assembly, and

a fabric pulling device for pulling the warp knit fabric from the stitch forming region.

The warp knitting machine is characterized in that the fabric pulling device is set up in relation to the stitch forming area in such a way that the warp knitting fabric can be pulled essentially horizontally forward in at least one first predefinable setting and essentially vertically downward in at least one second predefinable setting. The warp knit is pulled vertically forward on the tricot machine. The warp knit is pulled vertically downward on a raschel machine. The stitch forming area extends in a narrow band across the entire width of the warp knitting machine and has 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 the known warp knitting machines, in which the knitting tool is driven via a central transmission (crankcase), the formation of the stitches is only possible in a narrow limited space. Which is fixed by a movement sequence preset by a central transmission mechanism.

The design of the sinker assembly and the adjustability of the fabric pulling device are used in warp knitting machines for the production of warp knitting, for which purpose tricot and raschel machines must be purchased. Depending on the respective setting or switching of the fabric pulling device, completely different warp-knitted fabrics can preferably be produced without replacement of the knitting tool.

The sinker assembly can move along an arcuate path as is usual in warp knitting machines. The arc-shaped track can be clamped in the horizontal direction in front of the warp knitting machine. In front is the direction from which the warp knitting machine is normally operated and along which the tricot machine is pulled. The knockover edge and thus the longitudinal direction of the sinkers of the sinker assembly may be arranged at least partially parallel to the horizontal direction of the warp knitting machine during the formation of the loops. Preferably, the knockover edge is inclined forward by at least a maximum of 10 ° at the point in time of knockover of the coil when it is not parallel to the horizontal. The sinker assembly may also not perform movement during coil formation. The needle assembly may follow an arcuate track during the formation of the coil as is typical in warp knitting machines. The arc-shaped track can clamp the warp knitting machine in the vertical direction. The slightly longer needle handle may be oriented at least approximately parallel to the vertical line at least in time during coil formation. The needle may deviate from the vertical orientation by a maximum of 10 ° and then be tilted back, preferably with its hook. The needle is preferably inclined less strongly relative to the vertical than the outer edge of the knockover belt of the sinker assembly.

At least one first roller of the fabric pulling device arranged next to the loop forming area may be drivably and reversibly set in its rotational direction. Thereby, the pulling angle can be set and the accessibility of the coil forming area is maintained as much as possible.

At least one second roller of the fabric pulling device following the first roller can be arranged below the first roller in a first presettable setting of the fabric pulling device and can be arranged on the first roller in a second presettable setting of the fabric pulling device. Thus, the setting or switching of the fabric pulling device can be performed quickly. The necessary winding for a reliable carrying-in of the fabric tension process is present to a sufficient extent in both settings.

In general, 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 a machine frame, which comprises a plurality of intermediate walls, which are arranged offset from one another in the machine width direction. Typically, knitting tools used include crochets, yarn guiding elements (such as, for example, hole needles or yarn guiding tubes), sliders and knitting sinkers (such as, for example, tuck-in knockover sinkers, knockover comb sinkers or grip comb sinkers). The knitting tools are usually carried by bars, which are driven in the warp knitting machine by a respective lever shaft in such a way that they execute a pivoting movement independently of one another in a plane transverse to the lever shaft, i.e. in a plane extending in the machine height direction and in the machine depth direction. The guide bar carrying the thread-guide element, the heat-guide bar and additionally being supported and driven in such a way that it carries out a shifting movement in the machine width direction which superimposes the vibrations of its oscillating movement. Each of the guide bars filled with the crochet needle, the at least one guide bar filled with the knitting sinker and the at least one guide bar filled with the thread-guiding element is used for producing knitting positions of the warp knitted fabric in functional connection with each other. Depending on the type of warp knitting fabric and warp knitting machine, additional bars and knitting tools may be involved in this functional connection. A known embodiment of the warp knitting machine is a tricot machine in which the warp knitting produced is pulled forward approximately in the horizontal direction by a fabric pulling device, and a raschel machine in which the warp knitting produced is pulled down approximately vertically by a fabric pulling device by the machine. In this case, a pulling force acts on the warp-knitted fabric, which has an influence on the properties of the resulting warp-knitted fabric.

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

It has been known to date to produce not only four warp-knitted fabrics (which require four guide bars) but also warp-knitted fabrics requiring less than four guide bars in different batches on tricot machines with four guide bars. With the number of guide bars, however, the optimum oscillating movement of the guide element with respect to the crochet needle and the optimum oscillating movement of the crochet needle likewise change in order to ensure as rapid, efficient and error-free loop formation as possible. The pivoting movement of the crochet is designed in such a way that the crochet moves approximately vertically up and down during the warp knitting process. Thus, for example, in a warp knitting machine with four guide bars, the pivoting movement of the guide elements is longer than in a warp knitting machine with two guide bars. If two warp-knitted fabrics are to be produced on a warp knitting machine with four guide bars, the guide elements and the crochets must therefore travel 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 wobble movement may be necessary in order to be able to optimally match the knitting speed to the number of guide bars used. Warp-knitted fabrics, which for their production require a different number of guide bars, are therefore hitherto usually produced on different warp-knitting machines in an optimal knitting speed. Furthermore, warp-knitted fabrics are available which, on account of their composition, are produced firstly on account of their combination of stitch bonds and stitch bonds, either on the raschel knitting machine alone or on the tricot knitting machine alone. For example, a knitting chain with a high share (i.e. with stitch bonds in which yarns are laid in sequence in the same crochet in a plurality of stitch rows and thus have no connection to adjacent stitch segments) is not produced on a tricot machine and requires the use of a raschel machine.

In particular, warp knitting machines are advantageous which enable continuous production of batches of warp knitting with different compositions on a single warp knitting machine. For this purpose, the relative position of the lever shaft with which at least one guide bar can be driven and the lever shaft with which each at least one further guide bar can be driven is adjustable in the machine height and/or depth direction of the warp knitting machine. In order to vary the diversity of the composition of the fabric tracks of the manufacture of warp knit fabrics, the relative position may 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 an increased number of thread-guiding bars. For example, in a machine with four guide bars, the oscillating movement of the guide elements and the crochet can be optimally coordinated with the number of guide bars. If the textile product is to be produced in the same machine, which requires the use of two guide bars, the oscillating movement of the guide elements and the crochet hook cannot be optimally coordinated with a reduced number of guide bars on the machines used hitherto; the crochet can perform a shorter oscillating movement, for example in a warp knitting machine with only two guide bars, which increases the knitting speed. By adjusting the relative position of the lever shaft of the guide bar in the machine height and/or machine depth direction, the oscillating movement of the guide element can be matched to the changing oscillating movement of the crochet hook. Furthermore, for example in the case of a changeover of a warp knitting machine from a tricot machine to a raschel machine, the relative position of the lever shafts driving the guide bars can be adjusted such that the oscillating movement of the guide elements extends as far as possible in the machine depth direction over the height of the crochet needles, whereas the oscillating movement of the guide elements has a relatively large directional component in the machine height and machine depth direction over the height of the crochet needles with respect to its value in the tricot machine.

It is possible to use in all types of warp knitting machines according to the teachings of the present invention. It appears to be advantageous, however, that the teachings according to the present invention are applied at warp knitting machines which are only suitable for producing a single fabric layer (e.g. raschel machines without double segments or warp knitting machines which are suitable for producing a spacer fabric with two fabric layers). Typically, such machines have only a lever shaft in a knitting connection with the bar, which carries the crochet needle for which a torque is thus transmitted. The bar carrying the crochet is also referred to below as the needle bar (nadelbare). Advantageously, the different bars of such a machine work together to produce one fabric layer. In contrast to this, in a double-segment raschel machine, two fabric layers and a spacer knit with the two fabric layers are produced. The plurality of fabric tracks which are produced simultaneously on the warp knitting machine side by side in the machine width direction thus corresponds to the fabric layer, when all the crochets which are involved in the knitting process are driven by the lever shaft about the same axis of rotation.

With the further advantage that the angular range of the oscillating 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 the circumference with a fixed pivoting radius about the axis of rotation of the lever shaft. It is therefore advantageous, in particular in the case of varying the number of guide bars, to adapt the angular range of the oscillating movement. It is also advantageous if the angular range of the pivoting movement is adapted in the case of a change from tricot machine to raschel machine (or vice versa) in such a way that the pivoting movement extends as far as possible in the machine depth direction over the height of the crochet in the raschel machine, whereas the opposite pivoting movement has comparable directional components in the machine height and machine depth direction over the height of the crochet in the tricot machine. In any case, it is possible for such an adjustment to be carried out with the drive means as well, for example by switching on one or more gears. The same applies when the "yarn guide shaft" is not associated with a separate single drive, but the required torque is derived, for example, from a central drive or drives for at least two shafts. Likewise, the lever shafts associated with the other bars may advantageously undergo a change in the angular range of their oscillating movement. In connection with all embodiments of the invention, it is advantageously allowed that at least two drives are provided. An additional effect is that one of the drives is associated with the at least one guide bar. The other drive may advantageously drive the remaining bars. The remaining bars may however also be associated with a plurality of drives, for example one for each bar. As a further object, the control of a plurality of lever shaft drives is advantageously achieved in that one or more control devices are provided, which control the drives.

Particularly advantageous is a warp knitting machine 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 guide bar and the member drivable thereby. For example, the lever shaft of the guide bar may be rotatably received by an upper machine part about its axis of rotation. In an advantageous embodiment, the lever shaft of the guide bar is rotatably embodied about its axis of rotation by a bearing, wherein the machine upper part accommodates the bearing, which comprises at least two bearings.

An advantageous embodiment of the invention is a warp knitting machine, the machine upper part of which comprises at least two upper intermediate walls which are offset parallel to one another in the machine width direction and the machine lower part of which 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 at least one lever shaft. It is furthermore advantageous if each upper intermediate wall is connected to each lower intermediate wall in such a way that the relative positions of the intermediate walls to one another can be set. For example, each upper intermediate wall may be connected with each lower intermediate wall by a helical structure, wherein the helical structure comprises at least one threaded fastener and/or a mating threaded fastener, at least one through-bore or slot, and at least one threaded bore. It is likewise advantageous to have a screw structure of the threaded fastener instead of a mating threaded fastener, which is in functional connection with at least one mating pin. In this way, advantages are obtained for the manufacturers of such warp knitting machines with respect to the production costs and the holding costs, since such variable machines make the construction of a large number of variants unnecessary and also require fewer different types of components, so that different types of warp knitting machines can be produced.

It is advantageous for such warp knitting machines to comprise means for setting the relative position between the parts of the machine frame, such as the machine upper part and the machine lower part. A particularly advantageous means for setting the relative position is a spacer plate, which is arranged between the 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 to the sum of the thicknesses of the at least two spacer plates. It is thus possible to set a larger distance between the machine upper part and the machine lower part by combining at least two existing distance plates without the need for a distance plate of another thickness. Another advantageous means for setting the relative position between the machine upper and lower 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 machine lower part may comprise the at least one threaded bore and the machine upper part and the spacer plate comprise for each threaded bore at least one elongated hole. By displacing the machine upper 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 machine upper part and the machine lower part in the machine depth direction. It is particularly advantageous if the machine upper part and/or the machine lower part comprise dimensions in the machine height and/or machine depth direction, which enable an accurate and repeatable settable nature of the relative position. Another advantageous means for setting the relative position between the machine upper part and the machine lower part is a rail connection. A form-fitting rail connection is advantageous. Particularly advantageous is a rail connection which enables adjustability in the machine depth direction and/or the machine height direction and which is void-free in the machine width direction. It is furthermore advantageous if the rail connection comprises means for locking the relative position between the machine upper part and the machine lower part. It is also advantageous if the warp knitting machine comprises at least one 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 guide bar in the machine width direction into its oscillating deflection movement. The advantage here is that it is thus not necessary to adjust the relative position between the machine upper part and the machine lower part, and the connection between the at least one deflection drive and the at least one guide bar is likewise adapted, since the position of the at least one deflection drive relative to the at least one guide bar is unchanged. The preparation time for adjusting the relative position between the machine upper part and the machine lower part can thus be reduced.

Advantageously, the lever shaft is associated with one respective wobble drive for its respective wobble movement, wherein the wobble drive preferably comprises a motor. The wobble drive is used 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 the 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 stepper motor. It is particularly advantageous if the crank drive connects the linear stepper motor output shaft 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 drive converts the linear driving movement into a rotational movement of the lever shaft about its rotational axis. A great advantage of the crank drive is that even when the direction of motion is changed, it can be implemented as freely as possible and thus the drive motion can be transmitted without loss of motion share.

It is also advantageous if the at least one wobble drive comprises a rotary stepper motor. It is particularly advantageous if the winding transmission connects the rotary stepper motor output shaft to one of the lever shafts. For example, the lever shaft can be driven by a rotary stepper motor by means of a toothed belt, wherein toothed belt discs are arranged on the rotary stepper motor output shaft and the lever shaft, which are positively connected to the toothed belt. By means of a positive 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 machine upper part of which comprises at least one wobble drive for the lever shaft of the at least one thread-guide bar. In this way, a setting of the relative position between the machine upper part and the machine lower part can be achieved without matching the connection between the wobble drive and the lever shaft of the at least one guide bar, since the position of the at least one wobble drive relative to the lever shaft 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 machine upper part and the machine lower part is reduced. For example, the toothed belt must be replaced with respect to the toothed belt with a corresponding matching length each time the relative position between the machine upper part and the machine lower part is adjusted when the oscillating drive is connected to the lever shaft by means of the toothed belt, when the oscillating drive is not accommodated by the machine upper part.

Furthermore, it is advantageous for the warp knitting machine to have a plurality of wobble drives comprising motors. These motors can advantageously be controlled by means of an electronic control device. The electronic control means may comprise means for generating and enhancing signals, memory means and power electronics. Typically, it is a machine computer that provides control signals. Which in the case of a normal motor or suitable power electronics, such as an enhancement circuit (motor driver) adapted to operate a stepper motor. Finally, the motor is loaded with a suitable intensity of current, voltage, frequency or signal form for a matching motion profile. In this way, the electronic control device controls the driving movement of the motor, wherein the warp knitting machine converts the driving movement of the motor into the knitting movement of the knitting tool and the knitting tool is thereby driven by the motor.

Advantageously, the electronic control device is configured to operate the 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 sports 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 that match one another during their time sections. The presetting of the movement profile enables a targeted control of the braiding movement of the braiding tool. In the case of adjusting the relative position of the machine upper part and the machine lower part, the knitting movement of the thread guiding element can thus be newly coordinated with the relative position and knitting movement of another knitting tool, for example, and the warp knitting machine can be set more variably for producing batches of warp knitting with different diversity of components.

In order to continuously produce batches of warp-knitted fabric with different compositions, it is advantageous for the method to use at least two different wobble drives, from which the first at least drive the guide bar and the second at least drive the other bar and the movements of the two wobble drives are controlled in such a way that the guide elements of the guide bar and the needles of the other bar perform a braiding movement coordinated with one another. By using at least two different wobble drives, it is possible to control the wobble movements of the different bars independently of one another and thus to coordinate the knitting movements of the 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 shafts driving the guide bars has to be changed as a result of changing the batch of warp knitting.

It is particularly advantageous to carry out the actuation of at least two oscillating drives based on the stored movement profile, which are individually coordinated with the components of the respective batch. One motion profile here describes one specific knitting motion for each knitting tool. Advantageously, the movement profile is preset as input variable when preparing the warp knitting machine and is selected and programmed in accordance with the warp knitting fabric to be produced.

The movement profile of the knitting tools must be coordinated with one another depending on the selected composition of the warp-knitted fabric produced, in such a way that the knitting tools interact synchronously in order to produce the desired warp-knitted fabric. In order to produce warp-knitted fabrics of defined composition, there is thus a set of motion profiles coordinated with one another, which comprise exactly one motion profile for each knitting tool. Advantageously, at least two sets of mutually coordinated motion profiles are stored in the storage device and used according to the selected composition of the warp-knitted fabric produced. In this way, a matching movement profile can be selected in preparation for the warp knitting machine and no reprogramming is necessary.

Detailed Description

Fig. 1 shows in a symbolized view the front end of a sinker 1 according to the invention in a view in the width direction B. Sinker 1 comprises a knockover edge 2 which is of straight construction and is inclined forward (to the left in fig. 1). The grip edge 3 is located opposite the knockover edge 2 in the height direction H at a spacing. The knockover edge 4 connects the knockover edge 2 with the gripping edge 3 and restrains both backwardly (right in fig. 1). The knockover edge is limited forward by a knockover edge transition point 5, to which a steeply descending abutment edge 6 extending approximately in the height direction H is coupled. The abutment edge 6 has a recess in its lower region, which can serve as a holding device 9. The abutment edge 6 ends down in a support edge transition point 7, to which a support edge 8 is attached. The support edge 8 extends approximately parallel to the knockover edge 2 and at right angles to the abutment edge 6. The sinker 1 is present in the form of a section without its rear (right in fig. 1) for attachment to another machine element, such as, for example, a bar. The connection of the sinker 1 to the further machine element can be designed according to any known technique.

Fig. 2 shows, in a symbolized view, by way of example, two sinkers 1 of a sinker assembly 10 with a knockover belt 11 in a view from obliquely above and in front. The sinker 1 is generally implemented in the same way as the sinker 1 of fig. 1. The knockover strip 11 is placed on the support edge 8 and rests against the abutment edge 6. The abutment edge 6 and the support edge 8 are correspondingly covered in this view by the knockover strip 11. The knockover belt 11 bridges between the sinker 1 and the warp knit in the width direction B, which can be pulled downward in the height direction H as required via the upper edge of the knockover belt 11 and its outer side 12. The pulling of the warp knitted fabric can however also take place forward parallel to the longitudinal direction L and parallel to the ravel edge 2. As in fig. 1, only the front end portion of the sinker 1 is presented. Fig. 2 shows only a portion along the extension of the knockover belt 11 and sinker assembly 10 in the width direction B.

Fig. 3 symbolically shows an oblique view of the section of the knockover strip 11 facing the connecting means 13. The spacing element 14 embodied as a bulge of the connecting means 13 can be pushed between the sinkers of the sinker assembly 10 and set its desired spacing at its front end so precisely and stabilize it. According to fig. 2, two sinkers 1 can be spaced apart by means of the presented spacing element 14.

Fig. 4 shows the components of the warp knitting machine relevant to the invention in a symbolized view in the width direction B, starting from the loop forming region in the horizontally forward oriented direction Hz of the warp knitting machine, in the case of the setting of the fabric pulling device 15. Fig. 4 shows a sinker assembly 10 according to the prior art together with a sliding needle assembly comprising a needle and a slider. Warp knit fabric, shown as simple lines, is pulled approximately parallel to the knockover edge 2. The warp yarn is fed from above substantially in the height direction as usual, which is symbolized by a thread. The fabric pulling device 15 is presented in a first presettable setting 16. The first roller 18 of the fabric pulling device 15 rotates in the counterclockwise direction in this setting. The second roller 19 of the fabric pulling device 15 or the axis of the second roller 19 is arranged in the vertical direction V below the first roller 18 or the axis of the first roller 18.

Fig. 5 shows the same relevant components of the warp knitting machine in a symbolized view in the width direction B, but in the case of setting the fabric pulling device 15 in the vertical direction V. The fabric pulling device 15 is presented in a second presettable setting 17. The first roller 18 of the fabric pulling device 15 rotates in the clockwise direction in this setting. The second roller 19 of the fabric pulling device 15 is arranged above the first roller 18 in the vertical direction V. The warp knit is pulled through the knockover belt 11. The warp knit is pulled at a small angle relative to the vertical V. The rolls 18,19 or their diameters are not presented in the same proportion as the knitting tool.

Fig. 6 shows a schematic diagram of a warp knitting machine 126, the machine frame 125 of which is divided into two parts and comprises an upper machine part 101 and a lower machine part 102, wherein the lower machine part 102 is arranged on a machine tool 114. The machine part 101 comprises a lever shaft 103 which is rotatably supported in the machine part 101 and is connected to a bar carrier 107. The guide bar 108 is supported on the bar carrier 107 so as to be movable in the machine width direction z. The support is not represented here for the sake of simplicity. Furthermore, the warp knitting machine 126 comprises three further lever shafts 104,105,106, all three of which are rotatably supported in the machine lower part 102 and guide the knitting movement into the knitting tool via the bar carrier and the bars. The bar carrier and knitting tool are not present. The machine upper part 101 and the machine lower part 102 are connected to each other by means of threaded fasteners 111, wherein the machine upper part 101 comprises for this each threaded fastener 111 an elongated hole, the longitudinal axis of which extends in the machine depth direction x, and the machine lower part 102 comprises for each threaded fastener 111 a threaded bore. Other devices for connecting the machine upper part 101 to the machine lower part 102 are however also advantageously conceivable, for example a connection with lockable tracks. The machine upper part 101 is movable in this embodiment in the machine depth direction x relative to the machine lower part 102 by a value corresponding to the length of the slot. A spacer 110 is arranged between the machine upper part 101 and the machine lower part 102, with which the relative position of the machine upper part 101 and the machine lower part 102 in the machine height direction y can be set in the machine height direction y.

Fig. 7 shows the warp knitting machine 126 from fig. 6 in a view rotated at 90 degrees around the machine height direction y. The machine lower part 102 comprises three lower intermediate walls 113, which are offset from each other in the machine width direction z and are connected to a machine tool 114. The machine upper part 101 comprises three upper intermediate walls 112; a lever shaft 103 with which a thread guide bar 108 can be driven; a swing driver 115 for the lever shaft 103; and an offset drive 116 for the guide bar 108. Three spacer plates 110 and the machine upper part 101 are connected to the machine lower part 102 by means of threaded fasteners 111. The wobble drive 115 drives the lever shaft 103, with which the guide bar 108 can be driven, and the guide bar 108 as well as the guide element 109 perform a wobble movement about the axis of rotation of the lever shaft 103. At the same time, the shift drive 116 drives the guide bar 108 and the guide element 109 to a vibrating shift movement in the machine width direction z. The thread guiding element 109 performs a three-dimensional weaving movement by overlapping the oscillating movement and the shifting movement.

Fig. 8 shows a section a, the position of which is presented in fig. 6. Three spacer plates 110 are present in section. Two elongated holes 117, through which one threaded fastener 111 extends, are present in each of the spacer plates 110. The elongated holes 117 of the spacer plate 110 enable adjustability of the relative position of the machine upper part 101 and the machine lower part 102 in the machine depth direction x.

Fig. 9 shows the swing drive 115 of the lever shafts 103,104,105,106, which comprises a linear stepper motor 118, a linear stepper motor output shaft 119, a drive lever 120 and a joint 121 eccentrically mounted at one of the lever shafts 103,104,105,106. The linear driving movement of the linear stepper motor output shaft 119 is converted into a rotational movement of the lever shaft 103,104,105,106 via the driving lever 120 and the joint 121 eccentrically mounted at the lever shaft 103,104,105,106.

Fig. 10 shows the swing drive 115 of the lever shaft 103,104,105,106, which includes a rotary stepper motor 122, a rotary stepper motor output shaft 123 and a winding transmission 124. Preferably, the winding gear 124 is a toothed belt, which is positively connected to the toothed belt disk on the rotary stepper motor output shaft 123 and the lever shafts 103,104,105, wherein the rotational speed and torque of the rotary stepper motor output shaft 123 are converted into the rotational speed and torque of the lever shaft 103,104,105,106 without slip depending on the number of teeth of the toothed belt disk.

All four lever shafts 103,104,105,106 of the embodiment are associated with a swing drive 115, wherein they can be controlled via a common electronic control. The electronic control device comprises a storage device in which a movement profile for the knitting tool is stored and in which the knitting movement of the knitting tool is preset. In order to produce warp knit fabric 20, all knitting tools must perform knitting motions that are coordinated with one another. Thus, the stored motion profile is associated with a group that includes one motion profile for each one of the braiding tools (which coordinates with another motion profile in the group). The electronic control unit can control the oscillating drive 115 in such a way as to carry out a braiding motion coordinated with one another, depending on the selected group of motion profiles. It is possible to store motion profiles of different groups for warp knitting fabrics 20 with different diversity of components, respectively, which takes into account the matching of the knitting motion of the knitting tool to the components of the warp knitting fabric 20. In this way, the correct knitting motion can be set by selecting the motion profile of the correct group in the case of changing the composition of warp knit fabric 20.

Fig. 11 shows a schematic view of the spatial arrangement of the lever shaft 103 with respect to the thread guiding element 109 and the crochet hook 127, when the warp knitting machine 126 operates according to the principle of a tricot machine. The illustration is not drawn to scale, and particularly the radius of wobble 132 is presented too small relative to the other elements of the illustration. The bar carrier 107 and the guide bar 108 are not represented in fig. 11, in the warp knitting machine 126 but connect the guide element 109 with the lever shaft 103. The thread guiding element 109 performs a pivoting movement 128 around the lever axis 103 on a circumference with a pivoting radius 133, which has a directional component both in the machine depth direction x and in the machine height direction y. By this oscillating movement 128, the yarn 130 is preceded by a crochet hook 127, wherein the yarn travels through a yarn guide opening 134 of the yarn guide element 109 and follows the oscillating movement 128 in this way. In order to obtain the desired course of the pivoting movement 128, a depth offset 131 in the machine depth direction x and a height offset 132 in the machine height direction y are present between the lever shaft 103 and the crochet hook 127, which are coordinated with the knitting movements of all knitting tools.

Fig. 12 shows a schematic view of the spatial arrangement of the lever shaft 103 relative to the thread guiding element 109 and the crochet hook 127 when the warp knitting machine 126 operates according to the raschel principle. The illustration shows as much as possible the same elements as in fig. 11. The arrangement of the elements relative to one another is however distinguished on the basis of the Raschel principle: the oscillating movement 129 of the thread guiding element 109 has a substantially smaller directional component in the machine height direction y with respect to the oscillating movement 128 of a warp knitting machine operating according to the principle of the tricot machine. The oscillating movement 129 of the thread guiding element 109 thus extends in the raschel principle mainly in the machine depth direction y. In order to achieve this, the depth offset 131 between the lever shaft 103 and the crochet 127 is substantially smaller than in warp knitting machines operating according to the principle of tricot knitting machines, or the lever shaft 103 and the crochet 127 are arranged one above the other in such a way that there is no depth offset 131 between the two. When the swing radius 133 remains unchanged, the height offset 132 must be greater in raschel principle than in a warp knitting machine operating according to the tricot machine principle, so that the swing motion 129 of the yarn guiding element at the height of the crochet hook 127 extends mainly in the machine depth direction x. In this regard, the height offset 132 and the pivot radius 133 have approximately the same value in the raschel principle.

The warp knitting machine 126 described above, in which the lever shaft 103 with which the guide bar is driven is adjustable in its relative position to the other lever shafts 104,105,106 and thus also to the knitting tools 127,1 of these lever shafts 104,105,106 in the machine depth direction x and in the machine height direction y, can thus be operated by the correct setting of this relative position not only according to the raschel principle but also according to the principle of a tricot machine. This applies in particular when, in addition, the same fabric pulling direction 21 and the knitting sinker 1 of the warp knitting machine 126 are suitable for this.

Fig. 13 shows a schematic view of a warp knitting machine 126 according to the invention in a configuration for producing a warp knitting fabric 20 in the sense of a tricot machine. The fabric pulling device 15 is located in a first presettable setting 16, in which the resulting warp knit fabric 20 is pulled as far as possible in the horizontal direction Hz. The relative offsets 131,132 between the lever shaft 103 and the crochet hook 127 are set such that the thread guiding element 109 performs the oscillating movement 128 of the tricot machine, i.e. with similar directional components in the horizontal direction Hz and the vertical direction V as much as possible over the height of the crochet hook 127. The resulting stitch is knocked off by the crochet 127 by contact with the knockover edge 2 of the sinker assembly 10.

Fig. 14 shows a schematic view of a warp knitting machine in a configuration for producing a warp knitting fabric 20 in the sense of a raschel knitting fabric. The fabric pulling device 15 is located in a second predefinable setting 17, in which the resulting warp knit fabric 20 is pulled as far as possible in the vertical direction V. The relative offsets 131,132 between the lever shaft and the crochet are set such that the thread guiding element 109 performs a pivoting movement 129 of the raschel knitting machine, i.e. a movement in the horizontal direction Hz as much as possible at the level of the crochet 127. The resulting stitch is knocked off by the crochet 127 by contact with the knockover belt 11 and knockover edge 2 of the sinker assembly 10. There is a decisive difference from the configuration from fig. 13.
