Description

A TENSIONING DEVICE AND A METHOD FOR THE RETENSIONING OF WARP THREADS OF A WARP THREAD LAYER}

FIELD OF THE INVENTION The present invention relates to the field of weaving technology, in particular the warp re-stretching method of the tensioning device and warp thread layer according to claim 1, the combination of the tensioning device and tensioning frame according to claim 9, A drawing-in machine comprising the tensioning device according to claim 12 and a warp retensioning method of the warp layer according to claim 13.

Before fabrics, such as fabrics, are made in the weaving machine by the connection of warp threads and weft threads, the warp yarns must be passed to the loom harness in the following specific order. Elements of the loom harness generally include a weeding frame as well as a heddle frame, a heddle, and a warp stop vane. Warp stops In each case passing through the warp eye of the vane, the gap between the head of the weave and the two teeth of the weaving lead, the means for passing through the individual warp, usually wound to the length required for the warp beam As each passes, the end of the warp warp is then projected from the woven lead. And by assigning a headle to a particular headle frame, that is, introduced into one said frame, the fabric pattern is defined.

Since dotumari typically has hundreds to thousands of warp yarns wound in parallel over a certain width, the above procedure must be repeated as many times as necessary until the warp yarns are completely passed through the loom harness. These procedures have been performed by hand and are still performed manually as before, but a variety of machine designs are available that can automatically perform part of the process (semi-automatic tiller) or perform all procedures automatically (automatic tiller). Do.

The semi-automatic tiller is relatively cost-effective compared to the automatic tiller, but there is a big disadvantage that one worker needs to perform the manual process partially by 100% of the tiller. Productivity gains achieved in this way are not significant compared to manual diameter and the defect rate is relatively high.

Automatic tillers are well-known techniques and are commercially available in various embodiments. They use independent controllers for all the processes required to pass warp into the loom harness. The workforce's duties are limited to the preparation and monitoring of work procedures and functions as well as the supply and removal of raw materials. In this way, productivity can be improved several times compared to manual diameter, and the defect rate can be significantly reduced.

Automatic tillers are generally composed of two main units that can be moved relative to one another. One unit includes a device for preparing the warp (tension unit of the warp layer), and the other unit includes a device for adjusting the loom process and the loom harness (diameter unit). The passage unit and the tension unit move laterally with respect to each other during the passage process from the start to the end of the warp layer as the passage process proceeds.

The automatic tuber of the above-described embodiment always includes a tensioning device (a seal frame or a tensioning frame), to which the warp layer to be treated is applied. From this warp layer, warp yarns are individually picked up (separated) in successive order and are passed to the loom harness element by the diameter unit. For flawless separation of individual warp yarns, the warp yarns need to be tensioned to a specific initial tension on the yarn frame. This tension varies with the raw material and yarn quality. Significant force grows over the entire width of the warp, which changes during the passage process. In some circumstances, personnel intervention is required to readjust the initial tension. To avoid this problem, as in WO 02/101132, there is a solution for tensioning (partial tensioning) only a small amount of warp, ie the part located immediately before the separation point. It is true that by this means the overall force on the seal frame is reduced. However, this solution has the disadvantage that the partial tension is released by each movement of the seal frame relative to the telescopic unit, and the yarn must be retensioned once after the movement has taken place. The interaction required between the individual components for this procedure typically requires only a complex and cost-intensive manner and nevertheless requires movement procedures and operations that must be worked precisely and without defects.

Another kind of problem arises from the fact that the two main units, which are able to move relative to one another, take the form of weights with correspondingly high inertia, and also their weight depends on the particular field. However, since the diameter position relative to the position of the warp to be separated varies continuously during the diameter process, periodic movement of at least one of the two main units is essential. To alleviate this problem, for example, in WO 92/07127, a solution is proposed in which the unit to be moved is divided into a light weight part and a weight part, and the light weight part is moved to higher precision independently of the weight part.

Another solution for the movement of the diameter unit relative to the tension unit is described, for example, in CH 479735. This solution requires high precision in the positioning of the trough unit and the tension unit, for example the trough unit and the tension unit are located on a rail or flat steel plate, correspondingly costly, and in the case of changes to the material flow. The level of flexible coping in the

The object of the present invention is to overcome the above-mentioned drawbacks and to enable improved retension of the warp of the warp layer, i.e. it is simple to perform mechanically, reliably, accurately and flexibly, and is cost effective. Work high.

This task is achieved by the tensioning device according to claim 1.

An important aspect of the tensioning device according to the invention is in the first example in that the tensioning device can independently move itself by the adjusting action of the positioning mechanism and the locking element. For this purpose, the positioning mechanism needs to include only a single drive portion, thereby contributing to remarkable weight reduction. This independent movement and reduced weight allow the tensioning device to be placed with unique flexibility. Since the reliability and accuracy of the tensioning device is also determined by the guide rails, the bottom quality of the site where the device is placed is a minimum requirement. In particular, the cost is reduced in that a rail system or steel sheet is no longer needed.

Advantageous embodiments of the tensioning device according to the invention are specified in the dependent claims 2 to 8.

In a preferred embodiment, the tension unit has three bar members aligned approximately parallel to each other, wherein the first and second bar members form respective stops for at least one warp yarn, and the third bar The member may be moved between the first and second bar members to catch and retension the warp yarns. Due to this tension unit, it is generally possible to generate any desired retension. To traverse the tensioning unit, the third bar member is retracted to a position away from the remaining two bar members to accommodate the additional portion of the warp layer in the space lying between the other two bar members. In order to guide this additional part into this space and to avoid any jam between the tensioning unit and the warp layer, in each case one free end of the at least one bar member is tapered to a point. desirable. In this way, the third bar member can be moved through the eccentric mechanism, preferably to ensure driving over a wide adjustment range which is as simple as possible and at the same time space-saving.

In another preferred embodiment, the locking element has a clamping or latching mechanism that makes it possible, in particular, to simply, quickly and stably fix the support member in place on the guide rail. Such a mechanism can be performed, for example, by an electric motor or by an actuator which can be operated electromagnetically. On the other hand, the positioning mechanism for the distance between the supporting members preferably comprises a spindle drive which can be carried out in particular simple and space-saving and which also allows for very accurate positioning of the tensioning unit.

In particular, if the support member is mounted on the movable chassis, various arrangements of the tensioning device are ensured. Devices equipped in this way operate in particular on a plurality of tensioning frames, and there is no locally installed tensioning device on each tensioning frame. Thus, one of the two support members is fixedly connected to the movable chassis such that the movable chassis moves with the support member, and a correspondingly short chassis is sufficient for mounting the support member.

The above object is also achieved by the combination of the above-mentioned tensioning device and the tension frame according to claim 9.

An important feature of the combination according to the invention is that the guide rails are always exactly aligned to the tensioning frame in the manner necessary to retension the warp.

Preferred embodiments of the combination according to the invention are specified in the dependent claims 10 and 11.

Therefore, the guide rail is preferably designed as part of the tensioning frame, since only a portion of the warp is tensioned and only the force control of the tensioning frame is a minimum requirement. Since the tension frame is entirely lightweight, it may be mounted to be movable relative to the tension device. By this means, the tensioning frame can be moved relative to the tensioning unit if the tensioning unit itself is fixed, thereby enabling the overall continuous movement of the tensioning unit along the frame, thereby reducing the processing time required for the warp layer.

The above object is also achieved by a passing device for passing through the warp of the warp layer according to claim 12, including the above tension device.

An important feature of the trough device according to the invention is the simultaneous use of all the advantages of the tensioning unit according to the invention for the separation and diameter of the warp yarns. Thus, the trough device may in particular be mounted on a traversable chassis of the tensioning device, in the simplest case the separation unit and the trough unit being held on the tensioning unit and moved with the chassis.

Another advantageous embodiment of the trough device according to the invention is specified in the dependent claim 13.

The separating unit and / or the barrel unit is preferably mounted on a supporting member that does not support the tension unit. By this means, continuous further processing of the warp can be ensured, especially if the tension unit is not moved. This is the case when the supporting member is locked and the other supporting member-together with the separating unit and the diameter unit mounted thereon-is traversed to once again produce a clearance for movement of the tensioning unit.

The above object is also achieved by the method of re-tensioning the warp of the warp layer according to claim 14, using the tensioning device described above.

An important feature of the method according to the invention is the particularly simple of the positioning mechanism along the warp layer, by means of the selective locking of the support member and subsequent operation of the positioning mechanism of the tensioning unit, which no longer requires complicated drives or complex movements. It is possible to move. This in particular increases the reliability and accuracy of the method.

Advantageous further developments of the process according to the invention are specified in the dependent claims 15 and 16.

In another preferred refinement of the method, the warp layer is moved relative to the tension unit when the support member of the tension unit is fixed in place, so that the overall continuous movement of the tension unit along the warp layer continues. By this means, further warp retensioning is possible even with the locked tension unit, resulting in shortening the overall processing time of the warp layer.

In another preferred refinement of the method, the separating unit and the trough unit are moved along the warp layer following the movement of the tension unit, in which case the separated warp is passed through the elements of the loom harness. Therefore, the advantage of the retensioning treatment according to the present invention may be used for separating and passing warp in the same method.

In the following, the invention is elucidated by way of schematic description and specific examples with reference to the accompanying drawings. The same reference numerals are given to the same components or components of the same function.

1 shows a schematic conceptual view of a tensioning device S according to the invention on a tensioning frame R. FIG. The tensioning device comprises a first support member S-10 which can be moved along the guide rail FS by two guide elements S-11 and S-11 '. This first supporting member S-10 is here designed in the form of a carrier frame on a plane on which the positioning mechanism S-30 is held for the purpose of moving the tensioning unit S-40. The positioning mechanism S-30, as shown herein, may comprise, for example, a spindle drive capable of moving the tensioning unit S-40 back and forth in the plane of the carrier frame. Of course, depending on the performance and price, one may think of a choice of other suitable drives, such as rack drives or belt drives, or other drives known to those skilled in the art. Here, the tensioning device S-40 is similarly fixedly connected to the second support member S-20, which can be moved along the guide rail FS by the guide element S-21. For a clearer understanding, the carrier frame shaped first support member S-10 is shown as being blocked at the point where it is crossed by the bar shaped second support member S-20. However, in this embodiment, the carrier frame is of closed design. In this way, the entire tensioning device S can move along the tensioning frame R to retension the warp KF of the warp layer KFS being tensioned on the frame. For the individual locking on the guide rail FS of the first or second support member S-10 or S-20, respective locking elements S-12 and S-22 are installed. Here, the locking element S-12 is optionally incorporated into one of the guide elements S-11 or S-11 'of the first support member S-10, or the second support member S-20. As in the case of the locking element S-22 and the guide element S-21 of FIG. The locking elements S-12, S-22 are designed here as clamps which can be operated electromechanically.

In addition, the tensioning frame R itself is not necessarily such, but may be mounted to be movable relative to the tensioning device S. FIG. To this end, the tensioning frame may have guide elements R-10 and R-10 'that allow movement along the guide rail FS. The movement options of the tensioning device S, the tensioning unit S-40 and the tensioning frame R are each indicated by a double arrow.

When the warp layer to be tensioned is stretched on the frame R and the tensioning device S is connected to the guide rail FS, the tensioning procedure can be started. Here, clamp S-22 is initially closed and clamp S-12 is open. Tension unit S-40 is activated and part of warp layer KFS is retensioned. The retensioned warp KF can then be separated by, for example, a suitable processing unit and passed through the elements of the loom harness. For further treatment of the warp, the support member S-10 is moved by the positioning mechanism S-30 along the warp layer KFS until the retensioned portion of the warp layer KFS is processed. Thereafter, clamp S-22 is opened, and clamp S-12 is closed. There the positioning mechanism S-30 further moves the support member S-20 along the warp layer KFS until the tensioning unit S-40 covers an additional portion of the warp layer KFS. . After this, the clamp S-22 is closed, the clamp S-12 is opened, the tensioning unit S-40 is activated, and a further part of the warp layer KFS is retensioned and supported. The member S-10 may be moved. During this period, the support member S-10 remains stationary relative to the tensioning frame R, so that the tensioning frame is a continuous of warp yarns that have not been retensioned even in the "retensioning" stage of the support member S-10. It can be moved relative to the tensioning device S to ensure processing. Alternate transverse movements of the support members S-10 and S-20 may continue until all warp KFs of the warp layer KFS have been retensioned and / or separated and passaged.

Due to the fact that the tensioning device S according to the invention can be traversed on the guide rail FS, only the bottom quality at the site where the device S is to be placed is a minimum requirement. In particular, rail systems and steel sheets are no longer needed to support the individual components. In addition, the tensioning device S only requires a single drive system, which only needs to consider the precision of the movement of the components. All of this means that a relatively low cost is incurred for the tensioning device and the telescopic device mounted thereon, which makes it possible to reduce costs in preparation for installation of the device on the installation site. This can be added to the fact that the conveyance of the support member S-10 can occur even during detachment of the warp, thereby enabling substantially uninterrupted tension and diameter processing. At the same time, the tensioning device according to the invention is very lightweight and can therefore be arranged very flexibly. Further, by the above tension treatment, only a part of the warp yarn is always tensioned, so that only the force control of the tensioning frame R is a minimum requirement.

FIG. 2 shows a specific embodiment of the combination of the tension frame R and the aperture device E according to FIG. 1. The passage device E here is based on the tensioning device S according to the invention, has a traversable chassis S-50, a separating unit E-10 for warps in the elements of the loom harness and It further includes a diameter unit E-20. For the purpose of positioning the tensioning unit S-40 on the warp layer KFS, the first and second supporting members S-10 and S-20 are caught on the guide rail FS. The guide elements S-11 and S-11 'provide support and directional stability to the telescopic device E.

In this way, the tension frame R is disposed at a fixed position, but the aperture device E can be moved relative to the frame. In principle, however, the opposite arrangement is also possible, in which the tension frame R moves along the diameter unit E in a fixed position. In this application, the width of the frame R corresponds to at least the widest warp layer KFS to be treated. The frame R has a means for providing a warp layer having the tension necessary for the treatment. At the bottom, the frame R is firmly connected to the guide rail FS.

At the start of the diameter processing, the warp to be passed is transferred to the tensioning frame R and the warp layer KFS is stretched on the frame. In the case of using a woven lead, the frame is clamped to a mount provided therein. Thereafter, the aperture device E is positioned at the beginning of the warp layer KFS and is ready for the passage process, where the required number of helm frames and / or helm carrier rails and vane carrier rails are arranged in the heel stack portion. And it is inserted into the mounting portion provided for filling the store of the vane lamination portion and for inputting or programming the diameter pattern. Then, as the operation of starting the diameter processing begins, the diameter of the warp is generated in a manner known in the headle, vanes and weave leads up to the last warp KF programmed according to the diameter pattern. Heads and vanes having a warp inside are distributed according to a diameter pattern on a carrier rail provided for this purpose. The last warp KF to be passed through the gap of the woven lead projects forward from the woven lead.

For the purpose of moving the aperture device E along the guide rail FS, the support members S-10 and S-20 are respectively clamps S-12 and S-22 (detailed in FIG. 3). Has One clamp S-12 is fixedly connected to the telescopic device E, while the clamp S-22 includes a spindle drive S-31 (similarly shown in detail in FIG. 3). With the aid of the mechanism S-30, it can be moved laterally with respect to the diameter apparatus E. As shown in FIG. When the clamp S-22 is fixedly connected, the tensioning unit S-40 is positioned on a part of the warp layer (partial tensioning) for the purpose of retensioning the warp layer KFS.

In the initial state, when the clearance device E is positioned on the frame R and the separation unit E-10 is ready to hold the warp, the clamp S-22 is closed while the clamp S-12 ) Is opened. Over a portion of the warp layer KFS, the tensioning unit S-40 is operated so that the warp KF is provided with the tension necessary for defect separation. In each case, the separation of the warp yarns KF, where the separation unit E-10 holds the closest warp yarn KF and the diameter unit E-20 passes through the warp yarns to the elements of the loom harness (not shown). This is disclosed. During this process, in each case, the diameter unit E-20 moves a certain distance in the direction of the warp layer KFS so that the separation unit E-10 can hold the next warp KF to be separated. This forward movement is initiated by the spindle drive S-31.

When all warps in the portion of the warp layer to be tensioned by the tensioning unit S-40 are passed through, the clamp S-12 is closed and the clamp S-22 is opened. There, the spindle drive S-31 moves the constant distance clamp S-22 in the direction of the warp layer KFS so that a part of the warp layer KFS can be once again caught by the tension unit S-40. do. Thereafter, the clamp S-22 is closed, the clamp S-12 is opened, and the tensioning unit S-40 is operated. This process is repeated at the required frequency until the last warp KF of the warp to be processed is passed.

In summary, the diameter unit E and the tension frame R move laterally with respect to each other from the start to the end of the warp layer KFS as the diameter process progresses during the diameter process. When the end of the warp layer KFS reaches the end of the warp layer KF, the elements of the loom harness are released from the trough device E and the tension frame R, so that the trough device and the tension frame R become independent of each other. . For the purpose of separating the woven lead, a hazard frame and / or hazard carrier rail with the head, and also a vane carrier rail with vanes along with the warp, are removed from the diameter unit and the tension unit. Thus, the tensioning frame R and the aperture device E may once again be free and spaced apart from each other for the next passage treatment and / or preparation thereof.

In principle, the functional unit of the barrel device E is not limited to the division into the tension unit, the separation unit and the barrel unit. Possible dividing into the separating unit, the cutting unit, and the barrel unit may be provided for the passage of the warp yarn KF to the warp eye for the gap of the head, the warp stop vane and the weaving lead. In addition, the additional unit includes a housing of the hazard carrier rail or hazard frame, storage, separation and distribution of the hazard on the hazard carrier rail, a diameter of the warp yarn KF into the woven lead, and warp stop vanes on the vane carrier rail. Can begin to store, separate, and distribute and program, operate, and control equipment.

3 shows the tensioning device S on the guide rail FS of the tensioning frame R according to FIG. 2. Here, the chassis S-50 has been omitted for clarity so that the support members S-10 and S-20 can be clearly identified, and the support members have a positioning mechanism including a spindle drive S-31. It is connected to each other through (S-30). By this positioning mechanism S-30, the distance between the two supporting members S-10 and S-20 can be changed. The support members S-10 and S-20 have guide elements S-11 and S-21 which can be caught on the guide rail FS so that the tensioning device can be moved along the rail. Accordingly, the supporting members S-10 and S-20 are fitted with respective clamps S-12 and S-22, which can be operated electromechanically, for example, and the clamps S-12 and S-22. By alternating locking and the operation of the corresponding positioning mechanism S-30, stepwise movement of the tensioning device S on the rail FS is possible. The spindle drive S-31 is held on the first support member S-10, and the tension unit S-40 is held on the second support member S-20. Here, the tensioning unit S-40 can initially be traversed over the path defined by the positioning mechanism S-30. To this end, clamp S-12 is closed and clamp S-22 is opened. Further movement of the tensioning unit S-40 beyond this transverse path is made possible by the closing of the clamp S-22 and the opening of the clamp S-12, as a result of the supporting members S-10 and S-. The distance between 20) is increased once again by the operation of the positioning mechanism S-30, that is, the first supporting member S-10 is spaced apart from the second supporting member S-20. If this happens, this time the clamp S-12 is closed and the clamp S-22 is open, so that the locked support member S-10 is repeatedly moved forward of the tensioning unit S-40. Can function as a thrust abutment for To retension the warp KF, the warp is received between the two bar members S-41 and S-41 'and the third bar member S-42 of the tensioning unit on the one hand, and the third bar. The member may pivot through an intervening space between two bar members S-41 and S-41 '. Thus, the first and second bar members form a stop for the at least one warp yarn KF held by the third bar member S-42. The warp yarns KF retensioned in this manner can then be easily separated and then passed through the elements of the loom harness.

FIG. 4 shows a front view of the tensioning device S on the guide rail FS according to FIG. 3. In this figure, in particular the positioning mechanism S-30 can be clearly identified, and when the clamp S-12 is closed, it is possible to traverse the tension unit S-40 in the direction indicated by the double arrow. have. In contrast, when the positioning mechanism S-30 is operated with the clamp S-22 closed and the clamp S-12 open, the spindle drive S-31 is pushed further. Thus, stepwise forward movement of the tension unit S-40 on the warp layer KFS is possible. When the tensioning frame R is traversed relative to the supporting member S-10 so that the separation unit E-10 can separate the warp yarn KF in a non-intrusive manner at the time when the tensioning unit S-40 is tracked, Subsequent processing can be performed. For the secure capture of the warp KF, the two bar members S-41 and S-41 'of the tensioning unit have tapered free ends, while the third bar member S-42 has a warp KF. It is designed in the form of a roller to avoid damage. Due to the small and light structure of the tensioning device S, which can be particularly clearly identified in the side view, the tensioning device can be arranged with unique flexibility to create space for installation of additional functional units when mounting the troughing device. . The passing device E installed in the tensioning device S of the present invention allows particularly reliable separation and at the same time the passing diameter of the warp KF.

Finally, FIG. 5 shows a side view of a possible embodiment of the tensioning device S on the guide rail FS according to FIG. 3. In addition to the components already described, here it can be clearly identified how the third bar member S-42 is pivoted relative to the warp yarn KF. To this end, an eccentric mechanism S-43 is provided which takes up less space and at the same time enables simple positioning of long paths over that space. In the side view of the tensioning device S, the locking element S-12 can be better identified (although not visible behind it, but also the locking element S-22), respectively, the support member S-10 or It provides a recess in S-20 and can be closed against the guide rail FS extending in the recess by clamps S-12 and S-22.

Thus, the tensioning device S according to the invention can be arranged as an independent unit, but also provides a high functional basis for the construction of a trough device with additional functional elements. Due to its simple structure, the cost efficiency is particularly high in terms of reliable and flexible coping in manufacturing and manufacturing and maintenance. This advantage is also inherent in the tiller including the tensioning device, which significantly improves the quality and speed of the passthrough treatment.
