Description

  The present invention relates to a yarn splicing device.

  When manufacturing a fiber fabric, first warp into warps (referred to as a warp having a predetermined width for weaving or knitting), and then continuously processing this warp with another device to produce fibers. It is necessary to use a sheet material. A warp is required for weaving or knitting.

  When warping one warp, many yarns are drawn from one creel at the same time, and these yarns are wound on a warping drum or directly wound on a warping beam without going through a warping drum. . Generally, one creel can accommodate only a predetermined number of bobbins. For this reason, the number of yarns that can be drawn simultaneously from the creel may not be sufficient to produce a warp yarn of the full width necessary for weaving or knitting at a time. Therefore, warp is warped using a so-called warp band wound sequentially. The individual warp bands at that time coincide with each other. At that time, in general, the bobbin in the creel may be emptied before warping all the warp bands to finish the warp. In this case, the bobbin that is empty or substantially empty must be replaced with a bobbin that is sufficiently wound with a thread. After replacing the bobbin, it is necessary to tie the bobbin position after each bobbin position to the start end of the thread pulled out from the bobbin after replacing the bobbin. At this time, a yarn joining device is used.

  As a simple yarn splicing device, there is a tool that an operator uses by hand. The operator holds the tool in one hand, grasps the ends of the two threads with the other hand, that is, the end of the broken thread and the start of the new thread, and inserts the two threads into the yarn splicer. . Next, the desired yarn joining is performed by pushing the lever of the yarn joining device. In this method, after piecing, an operator can check whether the piecing has been performed correctly. However, such a splicing method requires a very long time and is a considerable burden on the operator.

  Therefore, an automatic yarn splicing device was provided on the creel. This yarn joining device is hung on a guide track in the creel and can automatically move to various operating positions. The yarn joining device performs desired yarn joining at each operation position. (For example, see Patent Document 1)

US Patent Publication No. 3220758

  However, in the yarn joining device, it is indispensable that a defect occurs at several percent of the yarn joining performed, and an operator sticks to the yarn joining device to monitor the defect. When a defect occurs, the operator must manually correct the defect. In addition, there is a V-type creel as a relatively large creel. In the case of this V-type creel, it is necessary to provide an independent yarn joining device for each side of the V-type creel. By using such a yarn splicing device, the V-type creel becomes very expensive.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a yarn splicing device that makes it easy to change the yarn in the creel.

  The yarn splicing device of the present invention is a yarn splicing device having a traveling device connected to a handle for enabling movement control by an operator, and on the traveling device, at least one yarn catching device, and at least One knotter and a suction device are arranged, the yarn catching device catches at least two yarns by a suction force, and the knotter splices two yarns caught by the yarn catching device, and the suction The device is adapted to apply a suction force to the yarn catching device.

  According to the yarn splicing device of the present invention, the various advantages of the manual knotter and the various advantages of the fully automated yarn splicing device can be combined, and the cost can be reduced. For example, one advantage is that one splicing device is sufficient for multiple creels or for bisected creel. As a result, the cost required for the yarn joining device in the creel is less than half that of a fully automated yarn joining device. Another advantage resides in that an operator who must run in parallel performs the movement control even with a fully automated yarn splicing device. In other words, the operator pulls or pushes the traveling device along a desired movement path where each yarn splicing position is arranged to move the yarn splicing device. In general, the creel is installed on a flat installation surface. Therefore, a large force is not required to move the yarn joining device, and most operators can push and pull it. can do. Further, since the yarn catching device is used, the time required for piecing can be kept short compared to the case where the operator performs the work manually. These make it easy to replace the yarn in the creel.

  In the above invention, it is preferable that a support is disposed on the traveling device, and the plurality of yarn catching devices and the plurality of knotters are disposed on the support in the vertical direction.

  According to the above configuration, a plurality of yarn splicing can be performed at one yarn splicing position. Such a plurality of yarn splicing is particularly effective in the case of a creel in which a plurality of bobbins are arranged one above the other. When a plurality of bobbins are arranged up and down, the operator simply pushes and moves the yarn joining device so as to be adjacent to the row of bobbins arranged up and down. Next, the yarn catching device is activated to catch the ends of the two yarns. The end of one yarn is usually on the yarn tensioner side and the end of the other yarn is on the bobbin side. The knotter is actuated to bind the ends of these two yarns. Thus, in the yarn joining device, yarn joining can be performed simultaneously on a plurality of bobbins.

  In the above invention, the yarn catching device and the knotter are preferably configured to be height adjustable.

  According to the said structure, it becomes possible to apply with respect to various creel. For example, the same yarn joining device can be used for various creels formed so that the distances in the vertical direction (vertical direction) of the bobbin position are different from each other.

  In the above invention, the energy storage device further stores energy for driving the yarn catching device, the knotter and the suction device, and the energy storage device is disposed on the traveling device. Is preferred.

  According to the above configuration, the yarn joining device includes the energy supply source that is indispensable for the operation thereof, and is not restrained by the energy supply cord during movement or the like. As a result, the yarn joining device can be applied to various creels. For example, when a battery or a battery is used as the energy storage device, the battery or the battery is disposed at a position where the center of gravity of the yarn splicing device is a preferable position. Thereby, the stability of the yarn joining device is improved.

  In the above invention, the energy storage device is preferably electrically connected to a charging terminal.

  According to the above configuration, the energy storage device can be charged again with the charging terminal, and it is not necessary to remove the energy storage device from the yarn joining device. When a battery or a battery is used as the energy storage device, the charging terminal can be formed by a plug or a socket, for example.

  In the above invention, the charging terminal is preferably arranged on the opposite side of the steering wheel in the traveling device.

  According to the above configuration, it is relatively easy for the operator to connect the yarn joining device to the charging station. The operator may simply push the yarn splicing device to the charging station and connect the charging terminal to the charging station.

  In the above invention, it is preferable that an operation device for operating the yarn catching device and the knotter is further provided, and the operation device is disposed adjacent to the handle.

  According to the above configuration, after the operator carries the yarn joining device to a desired position, the operator operates the operation device to cause the yarn joining device to perform a desired operation, thereby performing the yarn joining at one or a plurality of bobbin positions. It can be carried out.

  In the above invention, it is preferable that the traveling device has at least two wheels guided in the rail and at least two support wheels arranged to be shifted laterally across the moving direction of the traveling device. .

  According to the said structure, it is desirable to arrange | position a rail so that it may extend along the movement path | route of a yarn joining apparatus in the creel where a yarn joining apparatus is used. In that case, the yarn joining device is guided in the creel by this rail. The lateral stability across the rail is ensured by support wheels provided on the left and right of the rail in the direction of movement. Thereby, sufficient stability is ensured, and the yarn joining device can be moved in the creel at an appropriate speed.

  In the above invention, the support wheel preferably has a larger diameter than the wheel.

  If the said structure is followed, a traveling apparatus can be arrange | positioned in the state which maintained sufficient space | interval with a rail, for example, without producing the problem of stability.

  In the above invention, it is preferable that at least one position sensor is disposed in the traveling device.

  In accordance with the above configuration, the position sensor cooperates with a position segment located on the floor, rail or another suitable location. For example, when the yarn joining device is moved to the correct location, the position sensor generates a signal in the operating device. For example, green light is emitted when the yarn joining device is moved to the correct location, and red light is emitted when the yarn joining device is not disposed at a suitable location. The operator knows that the yarn splicing device is in the correct position by emitting green light (or generating another signal). Then, the operator can perform piecing at that position.

  According to the present invention, the replacement of the yarn within the creel is simplified.

A mobile yarn splicing device is shown.

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

  The yarn joining device 1 has a traveling device 2, and the traveling device 2 is connected to a handle 3. The traveling device 2 can be moved by an operator holding the handle 3 and pulling the traveling device 2 in the direction of the arrow 4 shown in FIG. 1 or pushing it in the opposite direction.

  Two wheels 5 and 6 are arranged in the traveling device 2, and the wheels 5 and 6 are fitted into the rail 7 and guided by the rail 7. The rail 7 is preferably arranged so as to extend along the movement path of the yarn joining device 1 in the creel in which the yarn joining device 1 is used. The traveling device 2 further includes two support wheels 8 and 9. The support wheels 8 and 9 have a larger diameter than the wheels 5 and 6. Whereas the wheels 5 and 6 are provided in the front-rear direction, which is the moving direction (see arrow 4), the support wheels 8 and 9 are spaced apart from each other in the lateral direction (left and right) across the front-rear direction. ing. That is, in the present embodiment, the traveling device 2 is supported on the floor or another base at four points of the wheels 5 and 6 and the support wheels 8 and 9.

  By being supported at four points in this manner, the yarn joining device 1 can be stabilized, and the yarn joining device 1 can be moved at an appropriate speed. Moreover, it is possible to keep the space | interval of the traveling apparatus 2 and the rail 7 fully by forming the diameter of the support wheels 8 and 9 by a large diameter. In addition, when there are irregularities in the base, there are cases where three points are supported.

  A wheel 6 disposed adjacent to the handle 3 is supported by the traveling device 2 via a swivel mechanism 10. Therefore, when the yarn joining device 1 is removed from the rail 7, it can move in a curved manner.

  A support 11 such as a pillar is disposed on the traveling device 2. The support 11 has a plurality of suction ports 12 arranged one above the other, and each suction port 12 has a suction port 13. Specifically, the suction port portion 12 can be rotated around the shaft 14 by a rotary drive device (not shown). The suction port portion 12 forms a yarn catching device 15 with the suction port 13 and the rotation driving device.

  The support 11 is further provided with a knotter 16, which is arranged in the vicinity of the yarn catching device 15. The knotter 16 has an operating device (not shown) in detail, and this operating device is synchronized with the rotational driving device of the yarn catching device 15.

  A plurality of groups of yarn catching devices 15 and knotters 16 are arranged on the support 11 in the vertical direction. In the present embodiment, six groups of yarn catching devices 15 and knotters 16 are provided on the support 11. However, the number of groups is determined according to the purpose of use. That is, it is determined according to the form of the creel where the yarn joining device 1 is arranged. For example, in the creel, when eight bobbin rows are provided in the vertical direction, it is preferable to provide eight groups of the yarn catching device 15 and the knotter 16.

  The suction port 12 is in a negative pressure (suction force) state by the suction device 17. The suction device 17 is disposed on the opposite side of the yarn catching device 15 via the support 11. The suction device 17 generates a suction force at the suction port portion 12 sufficient to take in the end 18 of one yarn hanging from the yarn tension device 19 and the start 20 of one yarn drawn from the bobbin 21. Let This suction force causes the end 18 and the start 20 to be sucked into the suction port 12. Next, when the suction port 12 is turned around the center of the shaft 14, the end 18 and the start 20 are inserted into the knotter 16. The notch 16 connects the end 18 and the start 20 to each other.

  Naturally, the yarn tensioning device 19 is not suspended in the air as shown in the figure, but is fixed to the support frame at the creel. The bobbin 21 is not hung in the air, but is hung on the creel at the bobbin position in the creel. Such a support frame and creel are omitted in FIG. 1 in order to make the yarn joining device 1 easier to see.

  Two batteries 22 are arranged on the traveling device 2. These batteries 22 serve as energy storage devices. The battery 22 supplies drive energy or control energy to, for example, the suction fan of the suction device 17 and the drive devices of the suction port 12 and the knotter 16. By mounting such a battery 22, when the traveling device 2 is moved, it is not restrained by a supply line (cord) for supplying electricity to the drive device. Thereby, the yarn splicing device 1 can be applied to various creels. The battery 22 is disposed at a position where the center of gravity of the yarn joining device 1 is preferable, for example, at a low position. Thereby, the stability of the yarn joining device 1 is improved.

  The battery 22 is electrically connected to a charging terminal 23 such as a plug or a socket. The charging terminal 23 is disposed on the opposite side to the handle 3 via the support 11 in the traveling device 2. Therefore, when charging the battery 22 again, the operator may move the yarn joining device 1 to the charging station (not shown in detail) by the handle 3 and connect the charging terminal 23 of the yarn joining device 1 to the charging station. Therefore, charging can be performed with a relatively simple operation, and it is not necessary to remove the battery 22 from the yarn splicing device 1 during charging, reducing the burden on the operator.

  The operating device 24 is disposed adjacent to the handle 3. The operating device 24 includes a plurality of operating elements 25 and at least one display unit 26. At least one position sensor 27 is arranged in the traveling device 2. The position sensor 27 is responsive to a position segment 28 provided on the rail 7. Location segment 28 is located on the floor, rail 7 or another suitable location. For example, when the yarn catching device 1 moves to a yarn joining position where the yarn catching device 15 catches the yarn by the suction port 12 and the knotter 16 can bind the yarn, the position sensor 27 and the position segment 28 are cooperated. The color of the display unit 26 is changed from red to green. As a result, the operator knows that the yarn joining device 1 is at the yarn joining position, and operates the operation element 25 accordingly, whereby six groups of yarn catching devices 15 for the yarn end 18 and the yarn start 20 are obtained. And the knotter 16 perform a yarn splicing process. On the other hand, when the position is out of the splicing position, the position sensor 27 and the position segment 28 cooperate to change the color of the display unit 26 from green to red.

  The plurality of yarn catching devices 15 and knotters 16 are arranged in the vertical direction. Therefore, in the creel having the bobbin rows arranged in the vertical direction, it is possible to perform piecing on a plurality of bobbins and to perform many piecings in a short time.

  The height of either the support 11 itself or the yarn catching device 15 and the knotter 16 can be changed. Accordingly, it is possible to cope with various creels having different bobbin positions. If comprised in this way, the same yarn splicing apparatus 1 can be used with respect to various creels. In some cases, the height adjustment function can be automated, and a position drive is provided for automation. The position driving device is electrically connected to a storage device that stores predetermined height positions for various creels. In this case, the operator can adjust the height position of the yarn joining device 1 according to each creel by a simple “button operation”.

  The advantage of the illustrated yarn splicing device 1 is that the operator does not perform the yarn splicing itself, but the operator himself only plays an auxiliary role, as compared with the case where the yarn is simply tied manually. The burden on the operator is reduced. In addition, since a plurality of yarn catching devices 15 and knotters 16 are provided, yarn splicing can be performed simultaneously on a plurality of yarns. The control cost for the plurality of yarn catching devices 15 and knotters 16 is relatively low, and the yarn joining device 1 can be realized at low cost. Then, only one yarn splicing device 1 is required for a plurality of creels or for a bisected creel. As a result, the cost required for the yarn joining device 1 in the creel is less than half that of a fully automated yarn joining device, one for each creel.

  Further, an operator who has been required to run in parallel even with a fully automated yarn splicing device can perform a moving operation. In other words, the operator pulls or pushes the traveling device 2 along a desired movement track where each yarn splicing position is arranged to move the yarn splicing device 1. In general, since the creel is installed on a flat installation surface, a large force is not required to move the yarn joining device 1, and most operators push or pull with this level of force. Can be. Since the yarn catching device 15 is used, the time required for piecing is kept short compared with the case where the operator performs it manually. This simplifies the exchange of the yarn in the creel.

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