Definitions

  • the invention relates to a method and a device for thread division on a warping machine according to the preamble of claim 1 and of claim 16.
  • Such a method and device is used to wind up individual groups of warp threads on the warping drum.
  • the thread division can serve to form so-called crosshairs, which are later processed, e.g. make it easier to tie the warp threads together.
  • the thread division can also be used so that the warp threads can be guided through the sizing bath with a sufficient spacing.
  • Another automated method is known for example from JP-B-62-2055. Accordingly, two parallel tubes are pushed over the opened thread structure, the tubes being connected in their inserted position at their ends by a fixed tube bend which is provided with a slot on its inner radius of curvature. Subsequently, a separating thread is introduced through compressed air or vacuum through one pipe, deflected at the pipe bend and returned through the other pipe, so that a thread loop can be formed which can be linked automatically after the two pipes have been withdrawn. With this procedure, individual warping bands can be subdivided. However, the process is extremely difficult to handle since the deflection of the separating thread by 180 ° and the formation of loops are very susceptible to faults.
  • the method should not influence the subsequent winding process and there should be no endangering of the individual threads or warping tapes.
  • the process of thread division should largely correspond to the well-known manual process, without having its potential sources of error.
  • the device should be easy to control and require as little operation and maintenance as possible. According to the invention, this object is achieved by a method which has the features of claim 1. In terms of the device, the object is achieved by a device having the features of claim 16.
  • the parallel introduction of separate individual sections and their subsequent connection to form a compact separating element is much easier to handle than pulling or shooting through a single separating thread, which is susceptible to faults.
  • the individual sections can be of very different properties and configurations, so that e.g. also have band-shaped and / or relatively stiff materials processed. By using different colors for the two individual sections, optical effects can also be achieved, so that e.g. twisting of a single warping belt in trees can be recognized immediately.
  • the separating elements can be inserted at any point in relation to the relative position of the warping drum, and various combinations of separating elements are also conceivable.
  • connection points of the individual sections can be attached to or within the normal width of the thread group. This reliably eliminates the impairment of adjacent warping belts by the connection points.
  • the two individual sections can be easily inserted even over greater depths of warp. Since the insertion takes place without contact with the thread bandage, adhesive tapes or adhesive tapes can also be processed.
  • the control of the feed or retraction movement individually or synchronously is particularly easy via pressure medium cylinders. A sufficient storage magazine on each holding element ensures that as many separating processes as possible can be carried out automatically without the need for maintenance.
  • a warping system 1 essentially consists of the warping machine 2 and the creel 3.
  • a plurality of coils 4 are located on the creel 3 attached, the threads 5 each pass a thread tensioner 6, which generates the desired thread tension.
  • Each thread 5 then passes a thread monitor 7, on which the thread is checked for its existence.
  • the threads pass freely to the cross reed 8, in which the threads 5 are given a specific position and sequence.
  • the threads are then passed through the warping reel 9, in which the threads are brought together to the desired warping bandwidth in order to be wound onto the warping drum 12 in a manner known per se via a deflection roller 11.
  • the warping drum 12 consists of a cylindrical part 13 and a cone part 14.
  • the individual tapes 15a, 15b etc. are thus not wound vertically one above the other, but offset horizontally. This prevents loosening of the threads on the warping drum 12.
  • tapes 15a to 15n After all the tapes 15a to 15n have been wound on the warping drum 12, they are wrapped together by the warping drum 12 onto the warp beam 16.
  • crosshairs for separating the threads 5 are created at the beginning and at the end of the warp or, if necessary, in between, the position of which is indicated by the positions 30, 31 and 32 in FIGS. 30 is an initial cross hair, 31 an end cross hair and 32 an intermediate cross hair, based on the warping drum 12.
  • the individual crosshairs 33 are fixed by separating elements 23 and 29, which each hold at least one partial thread assembly before and after the crosshair 33.
  • a single separating element 23 or 29 consists of two separate individual sections 38 and 39, which are connected to one another on both sides of the thread part assembly at the connection points 63.
  • crosshairs can be fixed with such separating elements, which are used in the form of a warp band. Rather, it is also possible to split individual thread sub-assemblies several times in succession to form a size division, so that the distance between the divided threads of an individual sub-assembly increases. The formation of a crosshair is described in more detail below with reference to FIGS. 3 and 4 and 6a to 6n.
  • the individual sections 38, 39 of an individual separating element are introduced, for example, with the aid of a sub-device 35, which is displaceably arranged on the warping table 34.
  • the device consists of two rod-shaped holding elements 44 and 45, which are arranged in parallel and can be displaced plane-parallel to the thread structure 10.
  • the holding elements can be extended and retracted with the aid of, for example, pneumatic lifting cylinders 48, 49, both a time-shifted and a synchronous movement is possible.
  • Each holding element is assigned a roller 36 or 37, on which a larger supply of the strip material is rolled up to form the individual sections 38 and 39.
  • each holding device 44, 45 a clamping device 42, 43 is arranged, on which the individual sections can be held.
  • the individual sections can be introduced relatively easily into the stretched thread structure, connected to one another and separated, as will be described below.
  • the introduction and connection of the individual sections could also be achieved in another way.
  • the individual sections could be shot in without the support of holding elements, or they could instead be swung in sideways in a linear motion.
  • the individual sections could also be held in place, for example, by vacuum or in some other way.
  • the starting position is shown in FIG. 1, the threads 5 being introduced in a fan-like manner from the thread monitors 7 to the deflection roller 11.
  • the thread assembly 10 is formed into the actual warping belt only after the point of impact on the deflection roller 11.
  • the threads 5 must first be brought to a plane 18 using the two rods 17 in front of the cross reed 8.
  • the cross reed 8 is then moved downward in the direction of arrow 19, the upper soldering points 20 located between every second tooth 21 deflecting every second thread down from the plane 18, so that a partial thread assembly 22 is formed. In this way, a compartment 24 is created between the stretched threads.
  • the two pressure medium cylinders 48 and 49 can be activated, as shown in FIG. 6c, so that the rod-shaped holding elements 44 and 45 fastened to the bolts 46 and 47 are pushed over the lower partial thread assembly.
  • the upper holding element 44 can penetrate into the compartment 24 unhindered.
  • the individual sections 38 and 39 are unwound from the two rollers 36, 37. The individual sections are held on the front of the clamping devices 42 and 43.
  • FIGS. 6d and 6e An intermediate step is shown in FIGS. 6d and 6e, which facilitates the attachment of the separating elements. From below, the two bolts 55 and 56 are placed laterally against the lower partial thread assembly 22 and moved towards one another in the direction of the arrows 53 and 54. The edge points 57 of the partial thread assembly are pushed together so that the width of the partial thread assembly 22 is reduced compared to the normal bandwidth.
  • connecting and disconnecting pliers 58 and 59 are inserted over the upper individual section 38 on both sides, as shown in FIG. 6e.
  • a connecting and separating table 60 is introduced by means not shown. In relation to their position relative to the warping bandwidth, these connecting and separating tools lie on the space obtained by pushing the lower thread part assembly 22 together within the warping bandwidth.
  • the connecting and separating pliers 57 and 58 are then activated, so that, according to FIG. 6f, the two individual sections 38, 39 are connected to one another on each side of the lower thread part assembly 22.
  • the connection can be made using a connecting blade 61, an adjacent separating blade 62 simultaneously separates the individual sections laterally to the desired length.
  • the two bolts 55 and 56 can in turn be extended and removed by means not shown.
  • the sub-device 35 can be moved back into a basic position in the direction of arrow 50.
  • the remnants of the separated individual sections are removed by means not shown in more detail, and new beginnings 40 and 41 of the upper and lower individual sections are hung in the clamping devices 42 and 43.
  • the sub-device 35 is now prepared for the creation of the second separating element 29.
  • the introduction of the second separating element 29 is shown in FIG. 4. To do this, the warping system 1 must first be moved a few centimeters in the crawl gear, after which it stops again. The cross reed 8 is then deflected upward in the direction of the arrow 26, the partial thread assembly 22 being deflected upward through the lower soldering joints 27 and thus again forming a compartment 24. The second partial thread assembly 28 remains held in the plane 18, held by the two rods 17.
  • the separating device 35 now travels in the direction of the arrow 62, so that the central axis 53 lies approximately at the level of the thread part assembly 22 which is deflected upward.
  • the first separating element 23 which has already been transported further on the warping drum 12 in the thread running direction, has been drawn.
  • the threads of the partial thread assembly 22 held together by the separating element 23 cross the second partial thread assembly 28 and reach the top in the plane shown in FIG. 6h.
  • the second separating element 29 is now inserted and fastened in steps not shown in the same way as the first separating element 23, so that according to FIG 6n the two separating elements 23 and 29 lie below and above the other thread subassembly 28 and the plane 18, respectively.
  • the two partial thread assemblies 22 and 28 lie directly next to one another, so that the image shown in FIG. 6n is practically obtained.
  • the crosshair 33 produced in the manner described is symbolically shown in FIG. 5a.
  • the lateral position of the separating elements 23 and 29 can be seen from the top view of the crosshair according to FIG.
  • the connection points 63 between the individual sections lie within the warping bandwidth and the total width of the separating elements corresponds approximately to the warping bandwidth. This ensures that, in the case of the side-by-side warping belts 15a to 15n on the warping drum 12, the individual separating elements do not interfere with the winding structure, as can be seen from FIG.
  • the separating elements When the crosshairs are formed, the separating elements always lie on the same plane, both in relation to their angular position and in relation to their diameter position.
  • several separating elements can be staggered one behind the other on a warping belt.
  • the crosshair formation can also take place in such a way that a separating element is attached to each of the two partial thread assemblies 22 and 28 on both sides of the crosshair.
  • the sub-device 35 could be designed in such a way that it can insert and attach the two separating elements lying one above the other at the same time.
  • the individual sections for forming the separating elements can be formed from very different materials such as plastic, textiles, metal foils, etc. Accordingly, versatile possibilities for connecting the two individual sections are also conceivable. In certain cases it can be from be of particular importance that the separating elements are arranged displaceably on the thread part dressing. In other cases, however, it may also be desirable that the two individual sections fix each individual thread of the partial thread association, which would be conceivable, for example, with the aid of an adhesive tape.
