European Patent Application No. 1479803

  An object of the present invention is to provide a pattern warp partial warper capable of achieving high productivity and a method for operating the pattern warp partial warp.

  The pattern warp partial warping machine of the present invention has a warping drum in which a plurality of transport surfaces movable parallel to the axis are disposed on the outer peripheral surface, and at least one disposed at the first end of the warping drum. A yarn guide device having two yarn guides, and a drive device for relatively moving the yarn guide and the warp drum in the circumferential direction. The apparatus further includes a second yarn guide device including a yarn guide, and the second yarn guide device is disposed at a second end portion of the warping drum.

  According to the present invention, it is possible to warp the pattern warp from both ends of the warping drum. Thus, for example, one of the two yarn guide devices can be provided for a new pattern at one end of the warping drum, and the other yarn guide device can be equipped with the warping drum. The pattern warp can be wound around the outer peripheral surface of the warping drum at the other end of the warp drum. Therefore, the preparation time can be kept short, and this short time can be used for production of the product. Thereby, high productivity can be achieved.

  In the present invention, it is preferable that the yarn guide and the warping drum relatively move at the second end portion in the same manner as the first end portion. According to the above configuration, for example, the yarn guides of both yarn guide devices operate to guide the yarn from the bottom to the top on the front side of the warping drum. Therefore, when the warp is unwound from the warping drum, it is only necessary to always rotate the warping drum in the same direction regardless of which end the yarn is wound around.

  In the above invention, the transport surface is preferably divided into two transport sections. Thus, when dividing a conveyance surface, it is preferable to classify by the axial direction center conveyance part of a warp drum. According to the said structure, one conveyance part can be stopped, for example, and only the other conveyance part can be moved. This is possible when the width of the warp band is small.

  In the above-mentioned invention, it is preferable that both the conveying sections can move so as to approach each other. According to the said structure, a yarn can be simultaneously wound up from the both ends of a warp drum, and a warp can be warped at both ends of a warp drum. This effectively halves the time required to wind the yarn around the warping drum. Moreover, the warp wound from each end when the warp is unwound from the warping drum can be combined.

  In the invention described above, it is preferable that a bridging element serving as a sliding surface is provided so that yarn can be fed to the sliding surface following the conveying surface. According to the said structure, the space | gap between conveyance parts can be bridged and a warp can be gathered together in the axial direction center of a warp drum by moving the conveyance part of a conveyance surface. Therefore, when the warp is wound, that is, when the warp is unwound from the warp drum and wound on the warp beam, the tension acting in the lateral direction of the yarn can be kept small.

  In the invention described above, it is preferable that the bridging element is disposed at least partially between the conveying surfaces in the circumferential direction and partially overlaps the conveying surface in the axial direction. According to the said structure, the space | gap which a thread | yarn can enter can be eliminated.

  In the above invention, the warping drum is divided into two parts in the axial direction, and there is a gap between the two parts, and a bearing device is provided in the gap. preferable. According to the said structure, a warping drum can be rotatably supported by the axial direction center conveyance part, and it becomes unnecessary to provide a bearing element etc. in an edge part.

  In the present invention, it is preferable that the transport surface extends in the axial direction of the warping drum and can move in both directions. According to the above configuration, the warp can be warped alternately from both ends of the warping drum.

  The method for operating the pattern warp partial warping machine of the present invention guides the yarn around the outer peripheral surface of the warping drum and feeds the yarn onto a conveying surface that moves parallel to the axis of the warping drum. The yarn is guided around the outer peripheral surface of the warping drum at both ends of the warping drum.

  According to the present invention, various prospects for improvement of product productivity arise.

  In the above invention, the yarn can be guided around the outer peripheral surface of the warping drum at both ends at the same time, and the conveying surface divided into at least two conveying portions in the axial direction of the warping drum is the yarn. It is preferable that at least the transport units adjacent to each end portion move in opposite directions. According to the above method, the warp can be wound simultaneously from both ends of the warping drum, and the time required for winding the warp onto the warping drum is effectively halved. Therefore, the warping time can be kept short and high productivity can be achieved.

  In the above invention, it is preferable that the yarn is alternately guided around the peripheral surface of the warping drum at both ends, and the conveying surface is alternately moved in the opposite direction. With this measure, the yarn can be guided and wound around the circumferential surface of the warping drum at one end of the warping drum, and the yarn guiding device and A corresponding creel can be reserved for different warpings. According to the method, the preparation time can be kept short. This is because it is not necessary to wait for the preparation of the yarn guiding device and the creel until the warp is wound around the warping drum and then unwound from there. After one warp is unwound, a new warp can be wound up directly.

  According to the present invention, high productivity can be achieved.

It is the side view which looked at the partial warp for pattern warps from the side. It is the top view which looked at the partial warp for pattern warps from the upper part. It is the front view which looked at the partial warp for pattern warps from the front. It is an enlarged view which expands and shows a bridge element.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  The pattern warp partial warper 1 shown in FIGS. 1 to 3 has a warp drum 2. In this embodiment, the warping drum 2 is divided into two sides 3 and 4. There is a space 5 between both sides 3 and 4, and a bearing device 6 is provided in this space 5. The bearing device 6 has a base 7 and is erected on a floor not shown in detail through the base 7. Therefore, both the sides 3 and 4 of the warping drum 2 are rotatably supported at a relatively small cost without providing bearing elements or the like at both ends of the warping drum 2. However, the warping drum 2 can be fixed in preparation for turning when the warp is wound, for example.

  The warping drum 2 may be supported by another method. For example, it is possible to use a shaft that is fixedly inserted to the outside of the end portion of the warping drum 2 and inserted.

  Each side 3, 4 of the warping drum 2 has a plurality of transport surfaces, and the plurality of transport surfaces are provided at intervals in the circumferential direction. Each conveyance surface is constituted by conveyance belts 8 and 9 (conveyance unit). These conveyor belts 8 and 9 are movable in parallel with the axis of the warping drum 2 as is known in the field of the pattern warp partial warper. Further, the conveyor belts 8 and 9 are arranged in parallel on the outer peripheral surface of the warping drum 2 with an interval in the circumferential direction. In this embodiment, the conveyor belts 8 and 9 are driven so as to run in opposite directions.

  As can be seen from FIG. 4, the conveyor belts 8 and 9 are arranged at the same position in the circumferential direction of the warping drum 2 so as to form one conveyor surface, and the bridging element 10 is interposed between the conveyor belts 8 and 9. It can be provided. The bridging element 10 bridges the gap in the axial direction generated between both the conveyor belts 8 and 9. The bridging element 10 has arms 11 and 12 that partially overlap the conveyance belt 8 in the circumferential direction and arms 13 and 14 that partially overlap the conveyance belt 9 in the circumferential direction. That is, the bridging element 10 partially overlaps the conveyor belts 8 and 9 in the axial direction. By overlapping in this way, the gap between the conveyor belts 8 and 9 can be eliminated, and it is possible to prevent the yarn from slipping into the gap and causing a failure. Further, by overlapping, when the conveyor belts 8 and 9 move in the same direction, the wound yarn band can be transferred from one conveyor belt 8 to the other conveyor belt 9. When the two conveyor belts 8 and 9 are moved in directions opposite to each other, the wound yarn band can be gathered in the center. By gathering in the center in this way, the tension acting in the lateral direction on the yarn can be kept small when rewinding, that is, when the warp yarn is unwound from the warping drum 2 or wound on the warping beam. . Although such an effect is exhibited, the bridging element 10 cannot be used when the warping drum 2 as shown in FIGS. 1 and 2 does not have the bearing device 6 at the center in the axial direction.

  A rotary creel 15 is disposed outside the left end of the warping drum 2, that is, outside the end of the side 3. A rotary creel 16 is disposed outside the right end of the warping drum 2, that is, outside the end of the side 4. The rotary creel 15 is coupled to a yarn guide device 17, and this yarn guide device 17 has a number of yarn guides 18. The rotary creel 16 is coupled to a yarn guide device 19, and the yarn guide device 19 has a number of yarn guides 20. Thus, the rotary creels 15 and 16 coupled to the yarn guide devices 17 and 19 can supply the yarn from one position on the extension line in the axial direction of the warping drum. Therefore, the load on the yarn is reduced, and it becomes easy to guide the yarn from the rotary creels 15 and 16 to the yarn guide devices 17 and 19.

  As is generally known for pattern warp partial warps, the yarn guides 18, 20 can move somewhat in the axial direction. Further, the yarn guides 18 and 20 can be wound around the outer peripheral surface of the warping drum 2 or can be separated outward from the respective end portions of the warping drum 2. Individual yarns can be fed to desired positions on the conveyor belts 8 and 9 by yarn guides 18 and 20.

  As can be seen from FIG. 2, both rotary creels 15 and 16 rotate in the same direction as indicated by arrows 21 and 22. That is, the yarn guides 18 and 20 move from bottom to top in FIG. 1 which is a side view and from front to back in FIG. 2 which is a plan view. That is, the yarn is wound in the warp drum 2 in the same circumferential direction, and regardless of whether the yarn is wound from the left end of the warp drum 2 or the right end, Yarn can be fed together.

  The pattern warp partial warper 1 shown in FIGS. 1 to 3 can operate as follows. First, the warping drum 2 is fixed. Each of the yarn guides 18 and 20 draws the yarn from the two rotary creels 15 and 16 and feeds the yarn onto the conveying belts 8 and 9 on the outer peripheral surface of the warping drum 2. The conveyor belts 8 and 9 move toward the direction of approaching each other from the outside of the warping drum 2, and when a yarn layer is generated on both sides 3 and 4, the conveyor belts 8 and 9 are finally small in the center of the warping drum 2. Only voids remain. Thus, the winding, that is, the winding of the yarn around the warping drum 2 is completed. The yarn is cut along a cutting rod, not shown in detail, and the cut warp can then be wound onto a warp beam. The gap between the warp yarns wound from the left and right end portions can be eliminated when the warp beam is wound.

  By moving the two yarn guiding devices 17 and 19 in this way, the yarn can be wound simultaneously from both ends of the warping drum 2, and warp is warped on both sides 3 and 4 of the warping drum 2. be able to. This effectively halves the time required to wind the yarn around the warping drum 2. Further, when the warp is unwound from the warping drum 2, the warp wound on each side 3, 4 can be combined.

  Further, in the partial warp machine 1 for the handle warp, for example, one of the two yarn guide devices 17 and 19 is provided for a new pattern on one side 3 of the warp drum 2. The other yarn guide device 19 can be used for winding the pattern warp yarn on the outer peripheral surface of the warping drum 2 on the other side 4 of the warping drum 2. Therefore, the preparation time can be kept short, and this short time can be used for production of the product. Thereby, high productivity can be achieved.

  The warping drum 2 is not supported at the center in the axial direction, but when it is supported by another method, one continuous conveying belt can be used. In this case, the conveyor belt can be driven in both directions. First, with the rotary creel 15, the yarn is fed only to the left end portion of the warping drum 2, and the winding layer is formed only by the left end portion. Can be generated. Next, as long as the rotary creel 15 operates with the yarn guide 18, the other end of the warp drum 2 is free. Thus, the yarn guide 20 can be prepared for the next warping process. When the warp is pulled out from the rotary creel 16 after the winding from the left end is completed, the warp can be wound from the right end of the warping drum 2 directly after that. That is, warping can be alternately performed from both ends of the warping drum 2. This eliminates the need for preparation time to wind the warp around the right end after winding it around the left end.

  Further, when there is no gap 5 between the both sides 3 and 4 and the warping drum 2 is supported by another method, the yarn guide 18 from one end is used while the conveyor belt 9 is not moved. It is also possible to process so as to wind the yarn on the conveyor belt 8. When the warp is finished on the conveyor belt 8, both the conveyor belts 8 and 9 are moved in the same direction to transfer the warp to the conveyor belt 9, and a new warp is wound on the conveyor belt 8. In that case, two warp yarns can be rewound in one rewinding step, and the warping time is saved. In this configuration, the second rotary creel (eg, rotary creel 16) can be used to save time in preparation for subsequent warping, but two rotary creels are not necessarily used. This is not necessary and is possible when the width of the warp band is small.

  The present invention is not limited to the embodiments, and can be added, deleted, and changed without departing from the spirit of the invention.

  As described above, the present invention provides a warping drum in which a plurality of transport surfaces that can move in parallel with an axis are disposed on the outer peripheral surface, and at least one yarn guide disposed at the first end of the warping drum. Suitable for a partial warp for a pattern warp, and a partial warp for a pattern warp having a yarn guide device provided with a drive device for relatively moving the yarn guide and the warp drum in the circumferential direction. This method is suitable for a method for guiding yarn around the outer peripheral surface of the warping drum and feeding the yarn onto a conveying surface that moves parallel to the axis of the warping drum.
