  In recent years, the above-described yarn winding machines tend to be multi-ended in order to increase the production amount, and the number of yarns wound at the same time is increasing. As a result, a lot of time is required to hang all the yarns on the traverse fulcrum guide. Along with this, the yarn sucked by the suction gun while threading the traverse fulcrum guide, that is, the yarn to be discarded increases, the production efficiency deteriorates, and the production cost increases. become.
  Further, since a high suction force is required to suck a large number of yarns with a suction gun, the suction gun is required to have a high pressure and a high flow rate. As a result, there is a problem in that the compressed air equipment is enlarged and the equipment maintenance cost is increased. Furthermore, there is a problem that the air consumption of the suction gun increases and energy loss increases. In order to solve these problems, it is necessary to shorten the time required for threading work on the traverse fulcrum guide.
  Therefore, an object of the present invention is to provide a yarn winding machine that can easily thread a traverse fulcrum guide.

It will be in the state gathered near the end. Further, when the knob 31a is pulled to the near side along the longitudinal direction, the guide support member 30 moves to the near side as shown in FIG. 4C, and the guide member 34 is located at the thread hooking position. At this time, as shown in FIG. 2, all the guide members 34 are located on the worker passage side with respect to the virtual straight line X.
  Here, as shown in FIG. 5A, one guide member 34 is provided with two traversing fulcrum guides 35 and 36 so as to be separated from each other in the longitudinal direction of the guide member 34. The traverse fulcrum guide 35 located on the opposite side of the support side of the guide member 34 is a bobbin mounted on one of the two bobbin holders 12 (located on the right side in FIG. 1) located at the winding position P1. This is a traversing fulcrum when winding the yarn Y around 20. The traverse fulcrum guide 36 located on the support side of the guide member 34 is threaded on the bobbin 20 mounted on the other of the two bobbin holders 12 located on the winding position P1 (the one located on the left side in FIG. 1). It will be a traversing fulcrum when winding up.
  The traverse fulcrum guides 35 and 36 each have a substantially U-shaped shape in plan view that opens to the side opposite to the support side of the guide member 34. In addition, as shown in FIG. 5B, when the plurality of guide members 34 are in the yarn hooking position, the traverse fulcrum guides 35 and 36 provided on each guide member 34 are arranged along the longitudinal direction. It is aligned on a straight line. That is, the traverse fulcrum guides 35 and 36 are alternately arranged in the longitudinal direction.
  Furthermore, as shown in FIG. 5B, the guide member 34 is inclined with respect to the longitudinal direction. When the guide member 34 is in the yarn hooking position, the guide members 34 adjacent to each other in the longitudinal direction partially overlap in the vertical direction. More specifically, as shown in FIG. 5A, the guide member 34 overlaps with the adjacent guide member 34 in the vertical direction in the vicinity of the end portion on the support side by a predetermined width. Further, a gap is formed between two adjacent guide members 34 that opens to the side opposite to the support side of the guide member 34 and continues to the traverse fulcrum guide 36.
  In addition, as shown in FIG. 5 (b), each guide member 34 has two notches 35a located between the end opposite to the support side and the traverse fulcrum guides 35 and 36, respectively. 36a are formed. The notches 35a and 36a are both notched toward the front side. Further, in a state where the plurality of guide members 34 are in the yarn hooking position, the plurality of notches 35a and 36a formed in each guide member 34 are aligned in a straight line along the longitudinal direction.
  Returning to FIG. 1, the yarn Y is pushed up on the support frame 17 so that the yarn Y is not applied to the traverse guide 18 when initial yarn hooking to the empty bobbin 20 is performed by the yarn hooking device 16 described later. The two left and right thread spring guides 22 are provided so as to be able to advance and retract with respect to the thread path. Further, the support frame 17 is configured to restrict the yarn Y supplied from above at the time of initial yarn hooking to a position corresponding to the yarn catching groove 21 of the bobbin 20 on which the yarn Y is hooked. A guide 23 is provided.
  Further, a yarn hooking device 16 for threading the empty bobbin 20 is provided between the two left and right bobbin holders 12 at the winding position P1. As shown in FIG. 1, the yarn hooking device 16 includes a guide support 24 and a yarn hooking member 25 movably connected to the guide support 24. The guide support 24 is erected on the bottom of the unit frame 10 and extends in the longitudinal direction. A plurality (ten in this embodiment) of thread hooking members corresponding to the plurality of bobbins 20 respectively attached to the two bobbin holders 12 at the winding position P1 on the left and right side portions of the guide support 24. 25 are arranged in the longitudinal direction.
  The yarn hooking member 25 is a member having a shape that is long in one direction, and has a gripping portion 26 that grips the yarn Y at a tip portion thereof. The yarn hooking member 25 is movable in the longitudinal direction and is driven in the longitudinal direction by a driving means such as a fluid cylinder.
  Furthermore, the yarn hooking member 25 is connected to the guide support 24 via a link mechanism (not shown) at the lower end thereof. Then, the thread hooking member 25 is retracted from the bobbin 20 attached to the bobbin holder 12 at the winding position P1 through the link mechanism, as shown by a solid line in FIG. Thus, it is configured to be movable between a thread pressing position that rotates toward the bobbin 20 and presses the thread Y gripped by the gripping portion 26 against the bobbin 20.
  In this embodiment, the left and right threading members 25 that perform threading operation on the bobbin 20 mounted on the two bobbin holders 12 at the winding position P <b> 1 are interposed between the two bobbin holders 12. Since the yarn winding machine 1 is arranged in a compact manner, the size of the whole winding machine can be reduced.
  Next, a procedure until the yarn bobbin 20 is wound on the empty bobbin 20 to start winding the yarn Y onto the bobbin 20 in the yarn winding machine 1 of the present embodiment will be described. First, as shown in FIG. 2, the plurality of guide members 34 are moved to the yarn hooking position. That is, the knob 31a (see FIG. 1) is pulled to the near side, the plurality of guide members 34 are brought close to the near end of the guide support member 30, and then the knob 31a is further pulled to the near side to support the guide. The member 30 is pulled out to the near side. Thereby, all the guide members 34 will be in the state pulled out to the worker channel | path side rather than the virtual straight line X (refer FIG. 2). Next, 20 yarns Y that are continuously supplied from a spinning machine (not shown) are sucked by a suction gun 50 and traverse fulcrum guides 35 and 36 provided on a plurality of guide members 34 at the yarn hooking position. Hang on.
  Here, when the 20 yarns Y supplied from above are hung on the traverse fulcrum guides 35 and 36, first, as shown in FIG. 6A, each of the ten guide members 34 is formed. The thread Y is held in the notches 35a and 36a. Thereafter, the 20 yarns Y are moved toward the support side of the guide member 34, and the yarns Y are hung on each of the 10 traverse fulcrum guides 35 as shown in FIG. At this time, all the ten yarns Y except for those hung on the traverse fulcrum guide 35 are located in a gap formed between the guide members 34 adjacent to each other. Further, the ten yarns Y between the guide members 34 are moved along the gap toward the support side of the guide member 34, and as shown in FIG. Multiply each.
  After threading the traverse fulcrum guides 35 and 36 as described above, the knob 31a is returned to the back side. Thereby, each guide member 34 is set to the traverse fulcrum position respectively opposed to the plurality of bobbins 20 mounted on the bobbin holder 12 at the winding position P1. Further, the yarn Y is passed through the space between the two bobbin holders 12 and the guide support 24 at the winding position P1. At this time, as shown in FIG. 2, the yarn hooking member 25 connected to the guide support 24 is brought closer to the front side and retracted from the bobbin 20 mounted on the bobbin holder 12 at the winding position P1. In position. At this time, the yarn splash guide 22 is advanced to raise the yarn Y so that the yarn Y does not hit the traverse guide 18 of the traverse device 15.
  Thereafter, the thread hooking member 25 is slightly rotated toward the bobbin 20 to cause the gripping portion 26 to grip the thread Y. Further, the yarn hooking member 25 in the state where the yarn Y is gripped is moved to the back side and is positioned so as to face the yarn catching groove 21 of the corresponding bobbin 20 as shown in FIG. At this time, the yarn regulating guide 23 is advanced to regulate the yarn Y in the longitudinal direction so that the yarn Y gripped by the yarn hooking member 25 does not come off the position along the yarn catching groove 21.

It overlaps by a predetermined width. In addition, the guide member 34 is opened between two adjacent guide members 34 on the side opposite to the support side, and a gap continuous with the traverse fulcrum guide 36 located on the support side is formed. Yes. Therefore, the yarn Y hung on the traverse fulcrum guide 36 located on the support side of the guide member 34 moves to the traverse fulcrum guide 36 through a gap formed between the adjacent guide members 34. At this time, the support side of the traverse fulcrum guide 36 is provided so that the adjacent guide members 34 overlap each other, so that the yarn Y is supported by the traverse fulcrum guide 36 without being caught by the traverse fulcrum guide 36. It can prevent moving to the side.
  Further, in the yarn winding machine 1 according to the present embodiment, each guide member 34 includes two cutting members positioned between the end opposite to the support side and the traverse fulcrum guides 35 and 36. Notches 35a and 36a are formed. The notches 35a and 36a are both notched toward the front side. Further, in a state where the guide member 34 is in the yarn hooking position, the plurality of notches 35a and 36a formed in each guide member 34 are aligned in a straight line along the longitudinal direction. Therefore, the thread Y can be temporarily held in the notches 35a and 36a before threading the traverse fulcrum guides 35 and 36. Therefore, even the yarn Y that is continuously supplied from the spinning machine and is swaying can be accurately hooked on the traverse fulcrum guides 35 and 36 by temporarily holding them in the notches 35a and 36a.
  Further, in the yarn winding machine 1 of the present embodiment, the guide support member 30 is in a state in which the pitch of the plurality of guide members 34 corresponds to the pitch of the plurality of bobbins 20 and the guide members 34 are gathered. The plurality of guide members 34 are supported so as to be able to expand and contract with respect to the size. Therefore, since the threading operation to the traverse fulcrum guides 35 and 36 can be performed with the guide members 34 assembled, the threading operation can be performed more easily.
