DE10159282C1 - Yarn laying assembly to lay layers of yarn bands, at a warp knitter, has transport chains for the carrier hooks on both sides composed of plate segments locked together in a force fit at the laying zone - Google Patents

Abstract

The assembly to lay bands of yarns in a number of layers between the hooks at transport chains (3,3') on both sides of a warp knitter, has guide rails for the transport chains in the laying plane to carry and tense the laid yarns. A drive (74,74') moves the transport chains between the entry and exit zones of the laying assembly. The transport chains are composed of articulated and interlinked plate segments (31,31'), forming a part of the guide hooks and structured to be engaged by the drive. The plate segments are held together in a force fit bond (PV). Guide rails give the plate segments the movement to tense the laid yarns and guide rails carry them forwards without kinking the bond between the plate segments. A drive (5,5') engages the final plate segment of each plate bond to give a sliding push movement.

Description

The invention relates to a laying arrangement for laying multilayer Thread laid in rows of hooks transport means on both sides of the Thread laid, with guide rails for guiding the means of transport in Direction of transport and for tensioning the laid scrim in the laying plane ne, with drive means for moving the means of transport between the Entry and exit area of the laying arrangement and with a back Guiding device for the means of transport from the exit area to the Entrance area of the laying arrangement, the two means of transport from a variety of individual, articulated together Plate segments exist, which have parts of the rows of hooks and the are equipped with elements for the attack of drive means.

By the term "laying arrangement" we mean a unit of several reren assemblies or devices, the threads, fiber strands, tapes or other initially endless elongated structures in a given Layer spreads, fixed and at the same time or at a later time the fabric created to carry out a subsequent operation transported.  

The term "scrim" also includes scrims made from fiber strands predominantly lengthways, very long fibers, scrims made of fiber tapes with predominantly differently oriented staple fibers and finally also scrims from foil tapes or from woven or knitted ribbons of different materials.

DE 20 12 114 A1 shows means of transport which are in the form of multi-link, endless link chains are formed. On this Link chains are arranged in plate-shaped elements that have hooks zen, in the reversible loops of the weft thread coulters, the thread to form layers should be hung. The transport chain is in fixed guides against lateral deflection by the Tension of the threads. These guides support the side Surfaces of the chain links and the rollers of the chains from below.

Such means of transport and their guides are for single-ply thread suitable. With increasing number of thread layers of the thread These are laid and with increasing working width of the laid scrim Guides for the transport chain no longer sufficient.

US Pat. No. 4,325,999 describes Trans port elements described, which consist of a variety of plate-shaped elements consist. These plate-shaped elements are articulated to one another held and form an endless traction device. The drive of this traction device takes place through the deflection roller pulling the upper run of the traction mechanism. There is a lateral guide for the traction device in the area of the laying arrangement not described.

What is disclosed, however, is that this traction device with its hooks runs along it a row are arranged, several differently aligned Can pick up and transport thread layers.  

The laying arrangement consists of at least two in different Directions of diagonally aligned laying devices, their thread layer or weft guide in alternating directions over the two Transport elements are guided. The diagonally laid thread layer, the the first laying device stretches between the transport chains, leads one of the transport chains opposite the pulling drive to pressure conditions in the means of transport, while on the other chain pure Tensile forces occur. Only when a second diagonal thread layer in Similar orientation - but opposite to the first layer - given up is brought, they rise in the transport along the direction of transport acting forces, which are generated by the thread layers, against each other other on. In this case, only the frictional forces caused by the higher weight of the scrim have considerable dimensions.

Is used as a traction device that is suitable for such forces, Glie derketten, then these stretch as a result of the different belas like a resilient system. In areas where pressure forces If one or more Glie buckle on the traction device the uncontrolled up or down.

By kinking or by stretching the chains on different sections of the laying arrangement different Ab would be effective between the hooks of adjacent plates. The fact that the thread layers in the middle area of the thread gel fix each other and the distances between the hooks in the lateral area vary from each other, be single or multiple Thread sheets held in an arc in the laid scrim. This lack leads to defective fabrics. The curved layers of thread are not suitable to absorb longitudinal forces in a satisfactory manner men.  

With the increase in the working width in the production of multi-layer This thread widened this shortage and leads to extreme cases Inoperability of the entire laying system.

To solve this problem, DE 100 11 132 A1 proposed the top two dreams of the transport chains of a Le arrangement to brace each other so that both dreams in the unoccupied condition have approximately the same (pulling) preload. To implement this measure, at least one of the first interrupted connecting shafts of the pulleys of the transport chains by a so-called tension coupling with the generation of a preload braced against each other and then fixed in this state.

With such an arrangement, significant improvements have already been made achieved with regard to the quality of the laid scrims. A disadvantage of this The arrangement, however, is that the pretensioning of the transport chains is very great must be chosen high. This leads to a heavy burden on the Chain links, to an increase in wear and ultimately to Shorten the lifespan of the very expensive transport chains.

It is an object of the present invention to provide transport elements for the to propose fabric to ensure that the Distances between the hooks of adjacent plate segments under all types of loads due to friction, due to tensile stress constant against the thread coulters and the mass of the laid scrim stay.

The overall structure of the transport elements should be simple and can be carried out in an endless cycle with little wear.  

This task is accomplished by designing the laying arrangement according to An saying 1 realized in a simple and reliable manner. Within the Laying arrangement are those with a uniform length Plate segments to form a frictionally held plate composite, of which at least that in the entrance area of the laying arrangement in each case the last plate segment of a continuous animal drive is subjected. After the thread gel has solidified ges - for example after the knitting point of the warp knitting machine one plate segment of the back, which is then freed from the laid scrim handover device. One with the return device again the plate segment has entered the entrance area of the laying arrangement ment is added to the panel assembly there without any gaps and pushed by the drive means against the panel assembly.

With this type of circuit design, all plate segments are precisely guided in the area of the laying arrangement. The distances between the Hooks within the closed row of hooks keep their respective Position also with differently tensioned threads, with different Mass of the scrim and with different friction ratio nissen.

After the scrim has been detached from the transport elements, can be done with simple means and without special quality requirements the transport back to the guide of the plate segments can be realized. The service life of these plate segments increases compared to previously used, drawn transport chains clearly. The trans port chains can be made smaller and lighter. You realisie only the return transport of the Plate segments.  

The use of drive means according to claim 2 makes the use proven machine elements possible. It is appropriate to go over the Area of engagement of the drive gear a support roller or fixed to the frame to store similarly effective supporting elements.

Are laid scrims, which are considerably asymmetrical are designed, it is appropriate according to claim 3, also in the area of Knitting point of the warp knitting machine before an additional drive means watch so that the entire panel composite in the area of the laying arrangement is positively driven.

The panel assembly can be non-uniform due to the drive (s) Way driven. So that we can B. possible to feed reduce as long as the row of needles is within the laid scrim located. This form of drive also allows the stitch length during correct the running of the machine.

With the embodiment according to claim 5, it is possible to adjust the voltage Thread layers and the scrim along the laying arrangement in Gren to correct zen in different ways.

The design of the leadership of the plate segments according to claim 6 si ensures that guide rollers and otherwise inexpensive sliding guides can be used.

With the guidance of the plate segments in the laying plane according to claim 7 a high precision of the positive guidance is guaranteed. The It is possible to use precise, standard ball bearing bearings. Au outside the laying area, d. H. in the return area, usual, simplified sliding guides are provided.  

The design of the feedback device according to claim 8 enables Use of conventional roller chains with a separate clutch structure or joints. As already mentioned, the roller chain itself has in terms of their traction only a pure transport function for the Plate segments.

The use of a partially playful transport chain according to An Proverb 9 ensures that the composite panel is only by the Ab measurements of the plate segments is defined.

The embodiment according to claim 10 has the same effect with the loading special feature that the joints of the roller chain in the usual way uniform, usual game can be made.

The embodiment according to claim 11 has the advantage that there are additional Rack profiles on the plate segments and additional drive there is no need for gears. The panel assembly starts here in the area of engagement of the driven sprocket. The large, curved engagement area makes additional support rollers unnecessary and is able to handle large loads to transfer driving forces to the panel system. The roller chain under there is no particular tensile or compressive load.

With the choice of a three-speed roller chain according to claim 12 one is in able to change the clutch without changes to standard chains function to the plate segment and the drive functions of the roller chain to be optimally implemented in connection with chain wheels.

When using plates that can be moved laterally in intermediate plates segments - according to claim 13 - can be done independently of the lateral Deformability of the roller chain the tension of the laid scrim in part Correct areas of the laying arrangement.  

The design of the feedback device according to claim 14 has the advantage a limited size. The optimized guide means on the plat Tenth segments can also be used for their return.

By modifying the design according to claim 14, it is possible to significantly reduce the number of plate segments in the return area ren. This is particularly useful if the laying arrangement with very many and / or very long laying devices.

The laying arrangement shown in Fig. 1 is used to produce a multi-layer laid scrim. At least two of the thread layers to be submitted are aligned in opposite directions to one another. The thread sheets are tensioned, fixed and conveyed in different, diagonal directions. Any number of other laying devices can be provided for under differently oriented thread layers.

The present laying arrangement has three laying devices 11 , 12 , 13 . The first laying device 11 places its family of threads at an angle inclined to the right to the transport direction. It forms the lowest layer of the scrim.

In this case, the second laying device 12 is oriented perpendicular to the transport direction and deposits thread sheets in the normal weft direction on the first thread layer.

A third laying device 13 is inclined to the left with respect to the transport direction, and in this direction deposits its thread sheets on the second layer. In the direction of movement of the transport means 3 , 3 ′, the knitting point of a warp knitting machine 2 is located close behind the third laying device 13 . The means of transport 3 and 3 'consist of a single slab segments 31 and 31 '.

These plate segments 31 , 31 'are put together in the laying area L of the laying arrangement and up to the knitting point of the warp knitting machine 2 in guides (not shown) to form a plate assembly PV ( FIG. 2), guided and driven.

The last seen in the direction of movement plate segment 31 a of the plate composite PV is driven by a drive device, here by the drive gears 5 , 5 '. The drive of these drive gears 5 , 5 'is provided by a motor 51 via the shaft 52 , which is mounted on the frame at 53 . The drive gears 5 and 5 'engage in racks on the underside of the plate segments 31 a, 31 a' and push the plate assembly PV built in front of them against the acting frictional forces and the effective thread tensions beyond the output area LA of the laying area L in the direction the knitting point of the warp knitting machine 2 .

After completing the knitting process on the warp knitting machine, that will be compacted and solidified scrims close to the hooks of the plate connected PV separated and a winder or fed further processing.

The plate segments 31 , 31 'freed from the laid scrim by means of a conventional cutting device, not shown, are returned by a return device 7 to the input area LE of the laying arrangement and there are successively re-attached to the composite plate PV.

The return device 7 , which is shown schematically in FIG. 2 as a side view, consists of an endless roller chain 71 , which is composed of coupling links 711 and tension links 712 . The coupling members 711 may have different or the same member dimensions. The coupling members 711 are each firmly connected to a plate segment 31 . The between two coupling members 711 to ordered tension members 712 are by an elastically applied force, for. B. by spring 72 , immediately before the plate segment 31 b reaches the plate assembly PV, deflected downward. In this way, the plate segment 31 b following the tension members 712 is non-positively applied with its end face to the plate segment 31 a, which is still driven.

The plate segments are in this case provided on their underside with rack profiles 35 . The plate segments 31 and the toothed rack 35 are chosen in its length so that the rack 35 has only complete tooth pitches. The module of the drive gear 5 , 5 'should be selected so that at least two teeth are always pushing in the engagement area.

A form of guidance for the plate segments 31 in the region of the plate composite PV is shown in FIGS . 4 to 6. In order to absorb the tension forces by the threads of the laid scrim in the horizontal direction and transversely to the transport direction, the plate segment 31 has two tension rollers 331 , 332 placed on top in the left area. These tensioning rollers 331 , 332 are supported on the inside of the guide rail 41 . A tensioning guide 333 designed as a roller ensures - if necessary - a sufficient form fit.

For the guidance of the plate segment 31 in the vertical direction, the support rollers 341 , 342 are arranged in the left area. They roll on the lower guide rail 42 . In the right area there is a single support roller 34 which rolls on the guide rail 43 . A lifting of the plate segment from the guide rails 42 , 43 prevents on the one hand the support guides 343 in the right area and the lower guide edge of the guide rail 41 .

On the top of the plate segment 31 there is the hook strip 32 in the usual way, which in the present case is equipped with guide hooks 321 and with retaining hooks 322 . The hook strip 32 is machined on the boundary edge or abutting edge to the adjacent plate segment 31 flush with this edge and contributes to the fact that the plate segments 31 in the plate composite PV are buckled against each other.

On the underside of the plate segment 31 , the rack 35 already described is fastened, which contacts a drive wheel 5 mounted on the frame. In the engagement area of the drive gear 5 , a support roller 46 ensures that the plate segments 31 are not deflected upward. The support guide 343 therefore only needs to be very light and can u. U. completely eliminated.

The distribution of the tensioning rollers 331 , 332 and the tensioning guide 333 and the support guide 343 and the support rollers 341 , 342 can be selected differently. However, it is expedient to fix roller pairs there where the greatest managers are required and precise guidance of the plate segments 31 is ensured even when an eccentric load ge.

A second variant of the guidance of the plate segments is shown in FIGS. 8 to 10. Four support rollers 36, in cooperation with grooves in the guide rails 42 "and 43 ", ensure a form-fitting guidance in the laying plane 40 . The tensioning rollers 331 , 332 are almost positively guided in a corresponding groove of the guide rail 41 ".

The guide rail 41 "is adjustable in the clamping direction of the scrim by means of adjusting device 45. In the region of the laying arrangement, multiple adjustment devices may be provided 45, which the guide rail 41 'in different positions along a path 48 to an imaginary line 47 (Fig. 1) approximately parallel can fix to the direction of transport.

For the slightly arcuate design of the guideway 48 , one can either use the elasticity of the guideway 41 "or use specially designed guideway sections. The shape of the guideway 48 regularly adjusts the tension of the thread layers in the scrim to the respective conditions. It can also be used during the run the machine.

To avoid a corresponding lateral deflection of the roller chain 71 used for the return, the latter can be firmly connected to an intermediate plate 75 ( FIGS. 8 and 9). The plate segment 31 ″ can be displaced transversely to the transport direction on the intermediate plate 75 and is held captively in a corresponding tongue and groove guide.

The drive of the plate segment 31 a "in the transport direction takes place here by the driven sprocket 73 ". A special rack 35 on the plate segment 31 "is not necessary for this.

In FIGS. 11-14, a further variant of the guide is of plates segments 31 '''described in the laying plane 40 and displayed. The guide for the plate segments 31 '''here consists of a shaft guide 49 and a parallel guide rail 44 . The latter is provided with a groove or with a bead, the walls of which are aligned approximately parallel to the radius of the shaft guide 49 .

The plate segment 31 '''has at its end facing the end of the thread an annular, open linear bearing 37 which is equipped with ball guides which roll on the one hand on the surface of the shaft guide 49 and on the other hand on the inside of a bearing ring. These linear bearings 37 provided with balls allow the plate segment 31 ″ ″ to be guided on the shaft guide almost without play, even when the row of hooks of the plate segment 31 ″ ″ is loaded on one side.

This shaft guide 49 and the parallel guide rail 44 guide the plate segments 31 '''only within the plate assembly PV in the laying plane 40 . Outside this area, return paths 81 , 82 take over the guidance of the plate segments 31 '''together with the roller chain 71 ', on which the base of the coupling link 311 is supported. In the return section, the web 81 and the web 82 can be guided in an arc around the chain wheels 73 'and 74 '''. No special requirements are imposed on the guides in the return area 7 . The guide only serves to ensure a certain position of the plate segments 31 '''and finally to ensure the insertion into the guideways of the shaft guide 49 and the guide rail 44 .

The roller chain 71 'is formed in this example as a three-pass roller chain au. The outer chain hoists 714 , 716 fulfill the usual drive function. Your chain links are only in operative connection with the teeth of the chain wheels, which serve to drive or guide the chain. The roller guides of the middle chain 715 offer the plate segments 31 '''and their link guides 311 the coupling joints 711 '. The coupling link 311 arranged on the underside of each plate segment 31 '''can positively engage around each of these coupling gels ke 711 ' and effects the coupling of the plate segment 31 '''by the chain 71 ' in every phase of the cycle.

As can be seen from FIG. 12, this guidance is also maintained in the return area and during the guidance by the chain wheels 71 ", 74 "'.

The drive effect in the entrance area LA of the composite panel is designed in this embodiment - as was described with reference to FIGS. 2 and 3 - in such a way that the tension members of the roller chain located between two coupling joints 711 'can preferably dodge downwards, so that the panel segments can form and reliably form each other to form the panel composite PV.

It is expedient that a point or line contact is ensured at the joints of the plate segments, so that a warping or evasion of the plate assembly from the preferred guide path is impossible. Such a line or point-shaped contact surface is also possible transversely to the horizontal direction of movement. This line contact is also ensured if the guideway 48 of the plate segments 31 '''is laterally curved. See Fig. 1a.

The adjusting device 45 'for producing the slightly curved path 48 is shown in FIG. 10. The shaft guide 49 is mounted here on a plurality of support arms 491 at larger intervals. Each support arm 491 has a balance lever at its lower end. By adjusting the fastening screws, which are arranged on both sides of the tipping point, a deviation from the imaginary straight line 47 can be set within certain limits.

In Fig. 7 a further variant of a feedback device 6 is described ben. A return path 61 below the laying level 40 described above with the guide rails 41 , 42 , 43 guides the plate segments 31 back into the input area LE of the plate composite PV.

A transmission lever 62 receives the plate segments te 31 individually in its position 62 '. The spring 621 is pressed together and the plate segment 31 is finally secured by the holding track 622 during the pivoting downwards into the return plane 60 against displacement by the spring 621 . In the lower region, in which the plates segment 31 in the area of the drive wheel 64 passes, the holding track is 622, the plate segment 31 free. The spring 621 pushes the plate segment 31 of the previously driven plate segment 31 and ensures the further transport of the forming second plate composite.

This second panel assembly is continuously moved to the rear end of the laying arrangement. There, a transmission lever 63 in position 63 ', in cooperation with the spring 631 and the holding track 632, picks up the foremost plate segment 31 in the same way as was described in relation to the transmission lever 62 . The plate segment 31 b is released again in the laying plane 40 and elastic to the z. Currently driven plate segment 31 a. This panel segment then takes over the propulsion of the panel composite PV in the laying level 40 .
