Description

  The present invention relates to a partial warp for warp warps having a warping drum, at least one yarn guide movable around the peripheral surface of the warping drum, and a rotary creel provided with a plurality of bobbin mounting portions. .

  The partial warp for pattern warp is used when producing a pattern warp or a short warp. During aging, the warping drum is generally stationary. At that time, one or a plurality of yarn guides rotate around the peripheral surface of the warping drum, and supply the yarns onto a conveyor belt that moves away from the yarn guide. At that time, the thread is pulled out from the bobbin disposed in the bobbin mounting portion of the rotary creel.

JP 2004-346480 A

  By using the rotary creel, a plurality of yarns can be used simultaneously when warping the warp yarns. However, since the number of bobbin mounting portions on the rotary creel is limited, in the case of warp, the patterns that can be created are limited. This is because only the same number of different threads as the bobbin mounting portion that can be used in the rotary creel can be used. If it is desired to diversify the design, the bobbin must be replaced by stopping the pattern warp partial warping machine while warping the warp so that the desired yarn can be incorporated into the warp. Stopping in the middle will reduce productivity. A similar problem occurs when the length of the yarn wound around one bobbin is less than the length of the yarn used as the warp. Even in such a case, warping of the warp must be interrupted, and this interruption reduces productivity.

  An object of the present invention is to provide a pattern warp partial warper having high productivity.

  This problem is achieved by a partial warping machine for a warp having a warp drum, at least one yarn guide movable around the circumferential surface of the warp drum, and a rotary creel provided with a plurality of bobbin mounting portions. A mounting mechanism is disposed adjacent to the rotary creel, the mounting mechanism having a handling mechanism capable of mounting a bobbin, and the handling mechanism is configured to attach the bobbin to at least one bobbin mounting part. This can be solved by moving it to a position so that it can be attached to the bobbin mounting portion.

  According to the present invention, the time required for replacing the bobbin can be significantly reduced by the mounting mechanism, in other words, the mounting robot. Specifically, the mounting mechanism can be operated immediately after the warp is stopped by the pattern warp partial warping machine, and the operator goes to the pattern warp partial warping machine to replace the bobbin. There is no need to wait until it is done. The bobbin mounted on the bobbin mounting portion of the rotary creel partially has a considerable weight and is generally 10 kg or more. Therefore, the burden on the operator is reduced by using the mounting mechanism. Accordingly, the risk of mistakes is reduced. Every time a mistake is made, the pattern warp partial warp must be stopped again. If this mistake can be eliminated, the stop time can be reduced, thereby increasing the productivity of the warp.

  In the above invention, the rotary creel and the mounting mechanism are connected to a common control device, and the control device replaces the bobbin according to the position of the bobbin mounting portion where a new bobbin should be mounted. It is preferable to determine the position of the rotary creel.

  According to the above configuration, the control device receives information on which bobbin mounting unit the new bobbin or another bobbin needs to be replaced, and controls the mounting mechanism in accordance with this information. The control device obtains from the program which defines the warp to be generated in which information on which bobbin mounting part a new bobbin or another bobbin must be mounted in. Therefore, the additional information necessary to operate the mounting mechanism is only a small amount of information that can be easily input to the control device by the operator.

  Particularly in the above-described configuration, it is preferable that the rotary creel is positioned at an exchange position common to all the bobbin mounting portions included in one group when the bobbin is replaced.

  According to this configuration, the structure of the mounting mechanism can be significantly simplified. When the mounting mechanism reaches the replacement position, the bobbin located there may be taken out and another new bobbin may be attached to the bobbin mounting part from which the bobbin has been taken out.

  When the other bobbin mounting part is waiting for the replacement of the bobbin, the control device simply turns the rotary creel so that the other bobbin mounting part comes to the replacement position. Then, it is only necessary to move the mounting mechanism to the replacement position so that the bobbins of the other bobbin mounting portions can be replaced.

  In the present invention, the handling mechanism preferably has two arms for mounting a bobbin.

According to the above configuration, one arm can be used when an empty bobbin or an unnecessary bobbin is taken out from the rotary creel, and the other arm can be used as a bobbin wrapped with a thread or a new bobbin. It can be used to attach to the bobbin attachment part of This shortens the processing time. This is because, when replacing the bobbin, the handling mechanism basically needs to run only once in the direction of the replacement position.

  In particular, in the above configuration, it is preferable that the arms can be alternately displaced to the same position. According to this configuration, for example, both arms are arranged at the ends of the two arms, and this lever can be rotated around an axis arranged at the center. In that case, it is only necessary to move the handling mechanism to the exchange position. One arm can hold the bobbin to be replaced in the bobbin mounting part, and when the handling mechanism is turned, the bobbin in the bobbin mounting part is removed and another bobbin is mounted and replaced by the other arm. . Therefore, the bobbin can be replaced without further displacing the handling mechanism from the replacement position.

  In the present invention, the mounting mechanism moves the handling mechanism in a first direction parallel to the rotation axis of the rotary creel and moves the handling mechanism in a direction perpendicular to the first direction. It is preferable to have the 2nd drive device which can be.

  If the said structure is followed, moving a handling mechanism to the bobbin exchange position desired can be implement | achieved with two drive devices. Thereby, the cost which must be spent in order to comprise a mounting mechanism can be reduced. Since the linear movement can be controlled at a small cost, the control is relatively simple.

  In the present invention, it is preferable that a bobbin magazine is disposed so as to face the end of the rotary creel opposite to the side facing the warping drum.

  If the bobbin magazine is arranged on the extension of the rotational axis of the rotary creel according to the above configuration, in order to take out a new bobbin from the bobbin magazine or lower an old bobbin or used bobbin to the bobbin magazine. It is sufficient to run the handling mechanism of the mounting mechanism in the direction along the rotation axis. Also with this configuration, the structure of the mounting mechanism can be simplified.

  In particular, in the above configuration, it is preferable that the bobbin disposed along the rotation axis is disposed in the bobbin magazine as in the rotary creel.

  According to this configuration, the bobbin may be simply rotated 180 ° without changing its posture or in some cases, while being conveyed between the bobbin magazine and the rotary creel. Thereby, the cost regarding control can be reduced.

  In the present invention, the bobbin magazine preferably includes a bobbin transfer mechanism for transferring the bobbin and mounting the bobbin on a handling mechanism.

  If the said structure is followed, the bobbin transfer mechanism is provided so that the bobbin in a bobbin magazine can be displaced to the direction which crosses the rotating shaft line of a rotary creel, for example. In that case, in order to be able to remove the bobbin from the bobbin magazine, the handling mechanism must be able to travel only in a direction substantially parallel to the axis of rotation. When the bobbin magazine has a plurality of “hierarchies” or bobbin groups arranged one above the other, it is necessary to displace the handling mechanism in the vertical direction. Incidentally, all bobbins arranged in the bobbin magazine can be gripped by moving the handling mechanism in a direction perpendicular to the first direction.

  In the above invention, the mounting mechanism preferably has a knotter. According to the above configuration, the mounting mechanism can not only replace the bobbin by exchanging the bobbin, but can also bind the yarn on the new bobbin to the yarn cut off from the old bobbin. The knotter can also be used to intervene when the thread breaks.

  According to the present invention, high productivity is achieved in a partial warp for pattern warp.

It is a top view which shows schematic structure of a part of structure of the partial warp for pattern warps.

  Hereinafter, the present invention will be described with reference to one preferred embodiment in conjunction with the drawings.

  The pattern warp partial warping machine 1 has a warping drum 2 which is only partially shown in FIG. The warping drum 2 is stopped when warping the pattern warp. A rotary creel 3 is disposed in front of one end of the warping drum 2 (to the left of the warping drum 2 in FIG. 1). In the rotary creel 3, a plurality of bobbins 4 are arranged at intervals in the circumferential direction, and two bobbin groups each including the plurality of bobbins 4 extend along the rotation axis 5 of the rotary creel 3. It is arranged before and after. The rotary creel 3 is driven to rotate around the axis 5 by a driving device 6.

  A thread guide 7 is disposed between the rotary creel 3 and the warping drum 2, and one thread guide 7 is disposed corresponding to each bobbin 4. The yarn guide 7 is connected to the rotary creel 3 so as not to be relatively rotatable, and rotates together with the rotary creel 3. Each yarn guide 7 pulls the yarn 8 from the corresponding bobbin 4 and supplies the yarn onto the peripheral surface of the warping drum 2 while rotating around the axis 5. Next, although not shown in detail, each wound layer of the yarn 8 is carried out of the rotary creel 3 by a known conveyance belt.

  One bobbin 4 can only wind a thread 8 of a limited length. If there is no winding thread wound around the bobbin 4 during one warping process, that is, while warping one warp, the empty bobbin 4 must be replaced with the bobbin 4 wound with the thread. Don't be. Such replacement of the bobbin 4 is also necessary when the number of bobbins 4 provided in the rotary creel 3 is smaller than the number of yarns required for the warp pattern.

  A mounting mechanism 9 is provided to enable such replacement of the bobbin 4. The mounting mechanism 9 has a handling mechanism 10 having two arms 11 and 12. The handling mechanism 10 can swing around the shaft 13 in the direction of the arrow 24. Bobbins 4a and 4b can be attached to the ends of the arms 11 and 12, respectively.

  The mounting mechanism 9 has a first track 14. The handling mechanism 10 can be displaced on the first track 14 in a first direction parallel to the axis 5. A first driving device 25 for displacing the handling mechanism 10 on the first track 14 is provided. The handling mechanism 10 can travel, for example, from the position indicated by the solid line to the position indicated by the broken line, and the handling mechanism 10 at the left position indicated by the broken line is next to the rotary creel 3.

  However, the handling mechanism 10 is arranged not directly on the first track 14 but via a second track 15 that can be displaced in a direction perpendicular to the direction in which the first track 14 extends. A second driving device 26 for displacing the handling mechanism 10 on the second track 15 is also provided. As a result, the handling mechanism 10 is displaced from the outside of the rotary creel 3 into the rotary creel 3 (to the position shown at the left end in FIG. 1), and the bobbins 4a and 4b attached to the handling mechanism 10 are rotated. 3 can be moved to the bobbin mounting portion 16.

  In order to replace the bobbin 4, first, the rotary creel 3 so that the bobbin mounting portion 16 on which the bobbin 4 to be replaced is mounted is disposed beside the mounting mechanism 9, more precisely, the first track 14. Is turned. Such an operation can be adjusted by the control device 27 that controls the rotary creel 3 and the mounting mechanism 9. The control device 27 receives information as to which bobbin mounting unit 16 must replace the new bobbin or another bobbin 4 and controls the mounting mechanism 9 according to this information. The control device 27 obtains information on which bobbin mounting unit 16 should generate a new bobbin or another bobbin 4 from a program that defines a warp to be generated. Therefore, the additional information necessary for operating the mounting mechanism 9 is only a small amount of information that can be easily input to the control device 27 by the operator.

  The control device 27 causes the handling mechanism 10 to travel on the first track 14 to the corresponding bobbin mounting portion 16. Then, the handling mechanism 10 is brought closer to the rotary creel 3 by the second track 15, and the bobbin 4 a to be replaced is held by one arm 11. When the bobbin is gripped by the arm 11, the handling mechanism 10 is rotated around the shaft 13 and the bobbin 4 b around which the thread is wound around the bobbin mounting portion 16 can be mounted.

  A bobbin magazine 17 is arranged on the extension of the axis 5 so as to face the end (left side in FIG. 1) of the rotary creel 3 opposite to the side facing the warping drum 2. In the bobbin magazine 17, a plurality of bobbins 4 c are arranged along the rotation axis similarly to the bobbins of the rotary creel 3. The bobbin magazine 17 has a bobbin transfer mechanism 18. The bobbin transfer mechanism 18 can grip the bobbin 4c in the bobbin magazine 17 and move it to the replacement position 4d. At the replacement position 4 d, the bobbin 4 c can be mounted on the handling mechanism 10 of the mounting mechanism 9 by the bobbin transfer mechanism 18. Further, the used bobbin 4 taken out from the rotary creel 3 can be lowered from the handling mechanism 10 to the bobbin magazine 17 at the replacement position 4d.

  In other words, before the bobbin replacement, the handling mechanism 10 is located at the end adjacent to the position 4d on the first track 14, and receives the new bobbin 4c around which the yarn is wound. Then, the bobbin replacement operation as described above is performed.

  The mounting mechanism 9 also has a knotter 19. This knotter 19 can be connected to the initial end of the thread of the bobbin 4 to replace the thread 8 of the bobbin 4 before replacement in the bobbin mounting portion 16. The knotter 19 can also be used when yarn breaks or the like.

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