  However, since the yarn winding member is individually provided for a plurality of yarns in the yarn winding device described in Patent Document 1, when performing yarn hooking on the bobbin, the operator must Therefore, it is necessary to perform an operation of attaching a plurality of yarns to corresponding yarn hooking guides, which makes the yarn hooking operation complicated.

  An object of the present invention is to provide a yarn winding device that can easily perform a threading operation.

  A yarn winding device according to a first aspect of the present invention is a yarn winding device for winding a plurality of yarns sent from above in a state of being arranged in one direction onto a plurality of bobbins. A bobbin holder that is formed in a long cylindrical shape and in which a plurality of bobbins are mounted in series at the same interval as the arrangement interval of the plurality of yarns sent from above, and is arranged below the bobbin holder to hold the plurality of yarns And a yarn holding unit movable along the axial direction of the bobbin holder, and a yarn placement unit for placing the plurality of yarns at positions corresponding to the plurality of bobbins held by the bobbin holder, The yarn placement unit extends in the one direction, and holds the yarn when the yarn holding portion moves along the axial direction of the bobbin holder in a state where the yarn connected to the yarn holding portion is in contact. In the direction of movement And a plurality of yarns that are formed at the same interval as the arrangement interval of the plurality of bobbins on the yarn guide portion, extend in a direction substantially perpendicular to the longitudinal direction of the yarn guide portion, and open at the tips thereof And an insertion gap.

  According to this, when the plurality of yarns are held by the yarn holding portion and the yarn holding portions are moved along the axial direction of the bobbin holder in a state where the yarns are bent by the yarn guide portion, the yarn holding portion However, when it comes to the same position as a certain thread insertion gap in one direction, the thread corresponding to this thread insertion gap comes on the thread insertion gap, and the extension direction of the thread is the extension direction of the thread insertion gap. Therefore, the yarn is inserted into the corresponding yarn insertion gap by the tension of the yarn generated by bending.

  On the other hand, when the yarn comes over a thread insertion gap that does not correspond, the thread holding portion is at a position different from the thread insertion gap in one direction, so that the thread is inclined with respect to the extending direction of the thread insertion gap. This prevents the thread from being inserted into the thread insertion gap because it is prevented from contacting the thread guide and being inserted into the thread insertion space.

  Accordingly, the plurality of yarns are inserted into the corresponding yarn insertion gaps by simply moving the yarn holding portion that holds the plurality of yarns along the axial direction of the bobbin holder, and the plurality of yarns are arranged at positions corresponding to the bobbins. be able to. In this state, by moving the yarn to a position where it is wound around the bobbin held by the bobbin holder, the bobbin can be threaded and the bobbin can be wound with the yarn.

  At this time, since it is only necessary to arrange the plurality of yarns so as to be held together by the yarn holding portion, there is no need to attach the plurality of yarns to individual members, and the threading on the bobbin can be easily performed. .

  A yarn winding device according to a second aspect of the present invention is the yarn winding device according to the first aspect of the present invention, wherein a portion of the front yarn guide portion where the yarn guide gap is formed contacts the yarn guide portion. Thus, it is separated from the bent yarn path.

  According to this, since the yarn bent by contact with the yarn guide portion does not come into contact with the yarn insertion gap separated from the yarn path in a state where it is on the non-corresponding yarn insertion gap, the yarn does not correspond to the yarn. It is possible to prevent the thread from being caught in the thread insertion gap when passing over the insertion gap.

  A yarn winding device according to a third aspect of the present invention is the yarn winding device according to the first or second aspect of the present invention, and prevents the yarn inserted into the yarn insertion gap from falling out of the yarn insertion gap. It further comprises a drop-off prevention part.

  According to this, it is possible to prevent the thread once inserted into the corresponding thread insertion gap from dropping out of the thread insertion gap.

  A yarn winding device according to a fourth aspect of the present invention is the yarn winding device according to the third aspect of the present invention, wherein the plurality of yarns are inserted into the corresponding yarn insertion gaps by the yarn placement unit. A yarn placement position for placing the yarn at a position corresponding to the bobbin, and a yarn hooking position for threading the bobbin around which the yarn inserted into the yarn insertion gap is wound around the bobbins It is possible to move between.

  According to this, since the thread placement unit in which the thread is inserted into the thread insertion gap is moved from the thread placement position to the thread hooking position, the thread can be hooked onto the bobbin. It is not necessary to provide a mechanism for moving the yarn arranged in this way to a position where it can be wound around the bobbin separately from the yarn arrangement unit for arranging at the corresponding position, and the configuration of the apparatus is simplified.

  A yarn winding device according to a fifth aspect of the present invention is the yarn winding device according to the third or fourth aspect of the present invention, wherein a portion of the yarn guide portion adjacent to the downstream side in the moving direction of the yarn holding portion is A notch that communicates with the thread insertion gap and that constitutes a drop-off prevention part is formed, and a wall surface of the notch downstream in the moving direction of the thread holding part is orthogonal to the longitudinal direction of the thread guide part It is characterized in that it is inclined to the downstream side in the moving direction of the yarn holding part with respect to the direction of movement.

  According to this, since the thread inserted into the corresponding thread insertion gap enters the notch, the thread is prevented from falling off from the thread insertion gap.

  In addition, when the yarn passes over the non-corresponding yarn insertion gap, a part of the yarn enters the yarn insertion gap, and the portion that enters the yarn insertion gap is located on the downstream side of the notch of the yarn holding member in the moving direction. It moves along the wall surface, and then comes out of the notch. However, if the wall surface on the downstream side of the notch in the moving direction of the thread holding member extends in a direction perpendicular to the longitudinal direction of the thread guide portion, the thread enters the thread insertion gap that does not correspond to the notch and then the notch Until the thread is pulled out, the thread does not move in the moving direction of the thread holding member, but suddenly moves in the moving direction of the thread holding member when the thread is pulled out from the notch. For this reason, when the thread is pulled out from the notch, the thread jumps up, moves over the corresponding thread insertion gap, and the thread may not be inserted into the corresponding thread insertion gap. Furthermore, even when the notch itself is not formed, the yarn moves along the wall surface on the downstream side in the movement direction of the yarn holding member in the yarn insertion gap. There is a risk that the thread will jump up when it comes out of the insertion gap.

  However, in the present invention, the thread that has entered the uncorresponding thread insertion gap enters the notch, moves along the inclined wall surface of the notch, and then comes out of the notch, so that the thread does not correspond to the thread insertion. The yarn holding member moves in the moving direction from the time when it enters the gap until it comes out of the notch. Therefore, when the yarn comes out from the notch, the yarn does not move suddenly in the moving direction of the yarn holding member, and the yarn jumping as described above can be prevented.

  A yarn winding device according to a sixth invention is the yarn winding device according to any one of the first to fifth inventions, and pushes out a plurality of bobbins mounted from the bobbin holder by moving in the one direction. The pusher further moves back in the direction opposite to that when the bobbin is pushed out to return to the position before pushing out the bobbin, and the yarn holding portion is provided in the pusher. .

  According to this, a plurality of yarns can be automatically inserted into the corresponding yarn insertion gaps by moving the pusher. In addition, it is not necessary to provide a dedicated mechanism for moving the yarn holding unit separately, and the configuration of the apparatus is simplified.

  A yarn winding device according to a seventh invention is a yarn winding device according to any one of the first to sixth inventions, wherein the yarn holding portions are connected to each other and have different surface directions. Provided with two vertical surfaces, and the yarn is held by hooking the connecting portion between the two vertical surfaces, and the upstream of the two vertical surfaces in the moving direction of the yarn holding portion. What is located is characterized in that it is inclined to the upstream side in the moving direction of the yarn holding portion with respect to a direction orthogonal to the one direction.

  According to this, when the thread holding portion further moves after the thread is inserted into the corresponding thread insertion gap, the tension of the thread increases, but when the tension of the thread increases to some extent, the thread is Since it is guided by the surface and sequentially falls out of the yarn holding portion, it is possible to prevent the yarn tension from becoming too large. Further, when the yarn holding portion further moves after the yarn is inserted into the corresponding yarn insertion gap, the yarn bending at the portion held by the yarn holding portion increases, but as described above, the yarn is held by the yarn holding portion. Since the yarn falls out from the portion, it is possible to prevent the yarn from being excessively bent. As a result, the load on the yarn is reduced, and a stable threading operation can be performed.

  According to the present invention, the plurality of yarns are inserted into the corresponding yarn insertion gaps by simply moving the yarn holding portion that holds the plurality of yarns along the axial direction of the bobbin holder, and the plurality of yarns correspond to the bobbin. Can be placed in position. In this state, by moving the yarn to a position where it is wound around the bobbin held by the bobbin holder, the bobbin can be threaded and the bobbin can be wound with the yarn.

  At this time, since it is only necessary to arrange the plurality of yarns so as to be held together by the yarn holding portion, there is no need to attach the plurality of yarns to individual members, and the threading on the bobbin can be easily performed. .

  Hereinafter, preferred embodiments of the present invention will be described.

  FIG. 1 is a side view of the yarn winding device according to the present embodiment, and FIG. 2 is a front view of the yarn winding device according to the present embodiment. In the following description, as shown in FIG. 1 and FIG.

  The yarn winding device 1 according to the present embodiment winds a filament yarn Y (hereinafter simply referred to as yarn Y) sent from above by a spinning device (not shown) around a bobbin B held by a bobbin holder 4 described later. It is for letting you take it. The yarn winding device 1 includes a plurality of yarn guides 2, a turret table 3, two bobbin holders 4, a contact roller 5, a plurality of traverse guides 6, a pusher 7, a yarn placement unit 8, and the like.

  The plurality of yarn guides 2 are arranged at the upper end portion of the yarn winding device 1 and are arranged in the left-right direction. The plurality of yarn guides 2 are respectively positioned and guided by the yarn Y sent from above, so that the plurality of yarns Y are arranged at equal intervals in the left-right direction (one direction). Sent.

  The turret table 3 is a circular plate-like body, and is rotatable about a rotation axis A1 that passes through the center and extends in the left-right direction. The two bobbin holders 4 are cylindrical members extending in the left-right direction (one direction), and are disposed on the left surface of the turret table 3 at a position shifted by about 180 ° with respect to the center of the turret table 3. . A plurality of bobbins B are mounted on the bobbin holder 4 in a state in which the bobbins B are arranged in the left-right direction at substantially the same intervals as the plurality of yarn guides 2 (yarns Y sent from above). For example, when the bobbin holder 4 is rotated about the rotation axis A2 extending in the left-right direction, the mounted bobbin B is also rotated.

  The contact roller 5 is a roller configured to be movable in the vertical direction by a moving mechanism (not shown), and presses the surface of the bobbin B around which the yarn Y is wound when the yarn Y is wound around the bobbin B as described later. Then, an appropriate pressure is applied to the yarn Y wound around the bobbin B.

  The plurality of traverse guides 6 are arranged above the bobbin holder 4 and are arranged at substantially the same interval as the yarn guide 2 in the left-right direction. The traverse guide 6 traverses the yarn Y in the left-right direction when winding the yarn Y around the bobbin B as will be described later.

  The pusher 7 is for pushing out the bobbin B from which the winding of the yarn Y has been completed from the bobbin holder 4, and includes a base portion 11, two pressing portions 12, and a yarn holding member 13.

  The base 11 is disposed below the turret table 3 and is attached to the cylinder 21 and is moved in the left-right direction by the cylinder 21.

  The two pressing portions 12 extend upward from the front and rear end portions of the upper surface of the base portion 11 to substantially the same height as the bobbin holder 4 that has reached the lowest position due to the rotation of the turret table 3. As a result, when the pusher 7 moves to the left, the pressing portion 12 abuts on the bobbin B mounted on the bobbin holder 4 and presses the bobbin B to the left, whereby the yarn Y is wound from the bobbin holder 4. Completed bobbin B is pushed out. The pusher 7 returns to the position before pushing out the bobbin B by pushing the bobbin B from the bobbin holder 4 and then moving to the right (in the direction opposite to when the bobbin B is pushed out).

  The thread holding member 13 is a member that collectively holds a plurality of threads when threading the bobbin B as will be described later, and is provided in a portion between the two pressing portions 12 of the pusher 7. . FIG. 3 is a view of the thread holding member 13 as viewed from above. The thread holding member 13 is a plate-like member, and has two vertical surfaces 13a and 13b at the right end (downstream side in the moving direction of the thread holding member). The vertical surface 13a extends in the left-right direction. The vertical surface 13b (of the two vertical surfaces located on the upstream side in the moving direction of the yarn holding member 13) is connected to the left end of the vertical surface 13a and extends leftward and rearward from this connection portion. (Inclined to the upstream side in the moving direction of the yarn holding member 13 with respect to the direction orthogonal to one direction). The yarn Y is held on the connecting portion between the vertical surface 13 a and the vertical surface 13 b, whereby the yarn Y is held by the yarn holding member 13.

  Further, as will be described later, in the yarn winding device 1, when the bobbin B is threaded, and when the yarn Y is wound around the bobbin B, the pusher 7 is moved to the right, whereby the yarn holding member 13 is moved. Is moved to the right (along the axial direction of the bobbin holder 4).

  As will be described later, the yarn placement unit 8 is for placing the yarn Y at a position facing the bobbin B (a position corresponding to the bobbin B) when threading the bobbin B. The table 3 is arranged at the same height as the upper end portion. The yarn placement unit 8 includes a swing arm 31, a fixed plate 32, and a plurality of bent plates 33.

  The swing arm 31 extends in the left-right direction, and is attached to a shaft 25 connected to a drive source (not shown), so that the yarn placement unit 8 can swing around the shaft 25. . The fixed plate 32 is a substantially rectangular plate-like body attached to the distal end portion of the swing arm 31 and having a longitudinal direction in the left-right direction.

  FIG. 4 is an enlarged perspective view of the vicinity of the bent plate 33 of the yarn placement unit 8. FIG. 5 is a view of FIG. 4 viewed from the direction of the arrow V. FIG. 6 is a view of FIG. 4 viewed from the direction of arrow VI. 4 to 6 show positions at which the yarn placement unit 8 places a plurality of yarns Y at positions facing the corresponding bobbins B (see FIG. 7A, yarn placement positions, as will be described later). FIG.

  As shown in FIGS. 4 to 6, the plurality of bent plates 33 are substantially rectangular plate-like bodies bent at a substantially central portion thereof, and are attached to the distal end portion of the fixed plate 32 in a state of being arranged in the left-right direction. ing. The bent plate 33 has one of two portions sandwiching the bent portion serving as an attachment portion 33a for attachment to the fixed plate 32, and the other is a thread insertion gap 34 and a drop-off prevention described later. A gap forming portion 33b for forming the gap 35 is formed. In the present embodiment, the bent plate 33 is a combination of the gap forming portion 33b and the mounting portion 33a in the vicinity of the gap forming portion 33b and the tip of the fixing plate 32 adjacent to the gap forming portion 33b. However, it corresponds to the yarn guide part according to the present invention, and the left-right direction is the longitudinal direction.

  The mounting portion 33a has a longitudinal direction in the left-right direction, and is fixed to the lower surface of the distal end portion of the swing arm 31 in the state shown in FIGS. The gap forming portion 33b has an obtuse angle with respect to the mounting portion 33a, and extends upward from the tip of the fixed plate 32 in the state shown in FIGS.

  Further, the gap forming portion 33b has a longitudinal direction in the left-right direction and extends longer on both sides in the left-right direction than the mounting portion 33a. Accordingly, a drop-off preventing gap 35 extending in the left-right direction is formed between the portion of the gap forming portion 33 b that extends longer to the right than the mounting portion 33 a and the fixing plate 32. Here, the drop-off prevention gap 35 is for preventing the yarn Y from dropping out of the yarn insertion gap 34 as will be described later.

  Further, since the bent plates 33 are arranged in the left-right direction, the gap forming portions 33b are also arranged in the left-right direction, and between the adjacent gap forming portions 33b are orthogonal to the longitudinal direction of the gap forming portion 33b. A thread insertion gap 34 extending in the direction (vertical direction in FIG. 5) is formed. The thread insertion gap 34 is open at the upper end (tip) of the gap forming portion 33b. A fixing plate 32 is located at the end of the thread insertion gap 34 opposite to the opening, and the thread insertion gap 34 communicates with the drop-off prevention gap 35 at this end.

  In addition, notches 33c are respectively formed in portions extending to the left side of the attachment portions 33a of the respective gap forming portions 33b adjacent to the right side of each of the yarn insertion gaps 34 (downstream in the moving direction of the yarn holding member 13). Is formed. Of the notches 33c, the notch 33c2 formed in the gap forming portion 33b2 other than the gap forming portion 33b1 disposed on the rightmost side has a wall surface 33d2 on the right side (downstream in the moving direction of the yarn holding member 13). It is inclined to the right side (downstream side in the moving direction of the thread holding member 13) with respect to the direction orthogonal to the longitudinal direction of the gap forming portion 33b2. The right wall surface of the notch 33c1 formed in the gap forming portion 33b1 arranged on the rightmost side extends in parallel with a direction orthogonal to the longitudinal direction of the gap forming portion 33b1.

  Next, a procedure for threading the bobbin B in the yarn winding device 1 and winding the yarn on the bobbin B will be described. FIG. 7 is a process diagram showing this procedure. FIG. 8 is a front view of the operating state of FIG.

  In order to thread the bobbin B in the yarn winding device 1 and to wind the yarn into the bobbin B, first, as shown in FIGS. 7A and 8A, the two bobbin holders 4 are The turret table 3 is rotated until the height is about the same as the center of the turret table 3. At the same time, as shown in FIG. 7A, the yarn placement unit 8 is swung so that the bending plate 33 is most forward during the operation described below. At the same time, the pusher 7 is moved to the leftmost in the drawing. When the two bobbin holders 4 are at the same height as the central portion of the turret table 3 as shown in FIG. 7A, the two bobbin holders 4 are used for threading on the bobbin B described later. Since the position is at an intermediate position between the position and the position for exchanging the bobbin B, the moving pusher 7 does not come into contact with the bobbin B held by the bobbin holder 4.

  Then, in this state (the state shown in FIG. 7A), an operator on the left side of the yarn winding device 1 sucks the plurality of yarns Y sent from above by the suction nozzle S and responds accordingly. The yarn guides 2 are sequentially threaded and further hooked on the connecting portion between the vertical surfaces 13 a and 13 b of the yarn holding member 13 provided on the pusher 7, and then the suction nozzle S is moved to the lower left of the yarn holding member 13. bring up.

  In this state, the plurality of yarns Y are in contact with the bent portion between the attachment portion 33a of the bending plate 33 and the gap forming portion 33b, and the yarn path on which the yarn Y travels is bent.

  Further, in this state, the yarn Y is not in contact with the tip of the gap forming portion 33b. That is, the tip of the gap forming portion 33b is separated from the yarn path of the yarn Y (see FIG. 9B).

  Next, the pusher 7 is moved to the right. Then, the yarn holding member 13 disposed on the pusher 7 also moves to the right (along the axial direction of the bobbin holder 4), whereby the yarn Y held by the yarn holding member 13 moves to the right. At this time, the portion of the yarn Y that contacts the bent plate 33 (the bent portion) is guided to the right by the bent plate 33 (in the moving direction of the yarn holding member 13).

  Then, as shown in FIGS. 8B and 8C, the thread Y is inserted into the corresponding thread insertion gap 34 in order from the left thread Y, and after it is inserted into the thread insertion gap 34, it falls out of the thread holding member 13. .

  The operation at this time will be described in more detail. FIG. 9 is a view showing a state in which the yarn Y moves on the bending plate 33 when the yarn holding member 13 is moved to the right, and FIG. 9A is a view seen from the direction of FIG. ) Is a view from the direction of FIG. FIG. 10 is a diagram illustrating a state in which the yarn Y held by the yarn holding member 13 moves when the yarn holding member 13 is moved to the right.

  When the yarn holding member 13 is moved to the right by the pusher 7, the yarn Y moves to the right while being in contact with the bent plate 33. Then, as shown by reference numerals Y1 to Y3 in FIG. 9, when one of the yarns Y is on the non-corresponding yarn insertion gap 34 or not on the yarn insertion gap 34, the yarn holding member 13 is Since the thread Y is at a position different from the thread insertion gap 34 in the direction, the thread Y is inclined with respect to the extending direction of the thread insertion gap 34. Thus, the yarn Y is not inserted into the yarn insertion gap 34 because it is prevented from being inserted into the yarn insertion gap 34 by contacting any part of the gap forming portion 33b.

  Further, at this time, since the yarn Y is separated from the tip of the gap forming portion 33b where the opening of the yarn insertion gap 34 is located, the yarn Y is prevented from being caught by the yarn insertion gap 34.

  Further, when the portion of the yarn Y in contact with the bent portion of the bent plate 33 of the yarn Y comes on the yarn insertion gap 34 when passing through the yarn insertion gap 34 that does not correspond, The portion temporarily enters the thread insertion gap 34. The yarn Y that has entered the yarn insertion gap 34 then moves while contacting the right wall surface 33d2 of the notch 33c2, as indicated by reference numeral Y2 in FIG. 9, and subsequently, as indicated by reference numeral Y3 in FIG. Then, it comes out of the notch 33c2 and comes into contact with the bent portion of the bent plate 33 again.

  At this time, if the right wall surface of the notch 33c2 extends in a direction orthogonal to the longitudinal direction of the gap forming portion 33b2, the thread Y moves to the right while moving along the right wall surface 33d2 of the notch 33c2. Therefore, the tension of the yarn Y increases as the yarn holding member 13 moves. Then, when it comes out of the notch 33c2, the tension suddenly moves to the right due to this tension. As a result, the yarn Y jumps up and moves to the position where it jumps over the corresponding yarn insertion gap 34. There is a possibility that Y may not be inserted into the corresponding thread insertion gap 34.

  On the other hand, in the present embodiment, as described above, the right wall surface 33d2 of the notch 33c2 is inclined, so that the yarn Y also moves along the right wall surface 33d2 of the notch 33c2. Then, it moves to the right along the inclined wall surface 33d2. Therefore, the tension of the yarn Y when coming out from the notch 33c2 does not become so large, and the above-described jumping of the yarn Y can be prevented.

  Unlike the other notches 33c2, the right wall surface of the notch 33c1 formed in the rightmost gap forming portion 33b1 extends in parallel with the direction perpendicular to the longitudinal direction of the gap forming portion 33b1. The thread Y inserted into the thread insertion gap 34 communicating with the notch 33c1 is the rightmost thread Y, and part of the other thread Y enters the thread insertion gap 34 and enters the right wall surface 33d1 of the notch 33c1. This is because it does not move along.

  On the other hand, when any one of the yarns Y comes on the corresponding yarn insertion gap 34 indicated by reference numeral Y4 in FIG. 9, the yarn holding member 13 comes to the same position as the yarn insertion gap 34 in the left-right direction. The extending direction of the yarn Y coincides with the extending direction of the yarn insertion gap 34. As a result, the yarn Y does not come into contact with any part of the bent plate 33, so that the yarn Y is inserted into the yarn insertion gap 34, and the inserted yarn Y comes into contact with the tip of the fixed plate 32.

  The yarn Y inserted into the yarn insertion gap 34 moves further to the right by the movement of the pusher 7, and is in contact with the wall surface 33d1 or the wall surface 33d2 on the right side of the notch 33c as indicated by reference numeral Y5 in FIG. It becomes. Thus, since the thread inserted into the thread insertion gap 34 enters the notch 33c, the thread Y inserted into the thread insertion gap 34 is threaded before being inserted into the drop-off prevention gap 35 as will be described later. It is prevented from falling out of the insertion gap 34.

  And the tension | tensile_strength of the thread | yarn Y becomes so large that the pusher 7 moves to the right side in the state which the thread | yarn Y contacted the wall surface of the notch 33c. When the tension exceeds a certain magnitude, as shown in FIG. 10, the portion of the yarn Y that is hung on the yarn holding member 13 is guided to the vertical surface 13b by its own tension, and left rear in the figure. To fall off from the thread holding member 13.

  In this way, after the thread Y is inserted into the corresponding thread insertion gap 34, the thread Y falls out of the thread holding member 13 when the tension exceeds a certain magnitude. It is prevented that the tension of Y becomes too large. Further, after being inserted into the thread insertion gap 34, the more the thread holding member 13 moves to the right, the greater the bending of the thread Y at the portion hung on the thread holding member 13, as described above. Since the yarn Y is inserted into the yarn insertion gap 34 and then falls out of the yarn holding member 13, the yarn Y is prevented from being excessively bent. And from these things, the burden concerning the thread | yarn Y becomes small and the stable threading operation | work is attained.

  Then, since the yarn Y that has fallen off from the yarn holding member 13 is pulled to the lower left in FIG. 9 by the suction nozzle S, it moves to the left and enters the drop-off prevention gap 35 as indicated by reference numeral Y6 in FIG. This prevents the yarn Y from falling out of the yarn insertion gap 34. In the present embodiment, the notch 33c and the drop-off prevention gap 35 described above correspond to the drop-off prevention unit according to the present invention.

  By the operation as described above, the plurality of yarns Y are sequentially inserted into the corresponding yarn insertion gaps 34, so that they are automatically arranged at positions facing the bobbins B, and the yarns that have entered the yarn insertion gaps 34 Y enters the drop prevention gap 35 and does not fall out of the yarn insertion gap 34. As described above, in the present embodiment, the plurality of yarns Y can be easily arranged at positions corresponding to the bobbins B simply by moving the yarn holding member 13 that bundles and holds the plurality of yarns Y to the right. Can do.

  In the present embodiment, the yarn holding member 13 is provided in the pusher 7 for pushing out the bobbin B on which the winding of the yarn Y has been completed as will be described later, and the yarn holding member is moved by moving the pusher 7. 13 is moved, a dedicated mechanism for moving the yarn holding member 13 is not required separately, and the configuration of the apparatus is simplified.

  At this time, the yarn Y is held in the yarn insertion gap 34 or the drop-off prevention gap 35, but these are higher than the yarn hooking guide of Patent Document 1 described above, and therefore the yarn insertion gap 34. Alternatively, the degree of bending of the yarn Y in the drop-off prevention gap 35 is smaller than the degree of bending of the yarn in the above-described yarn hooking guide of Patent Document 1. Accordingly, the load on the yarn Y is reduced, and a stable yarn hooking operation is possible.

  Next, as shown in FIG. 7B, the yarn placement unit 8 is swung clockwise as viewed from the direction of FIG. 7, and the turret table 3 is rotated counterclockwise as viewed from the direction of FIG. Then, the contact roller 5 is moved downward.

  Then, the fixed plate 32 and the bent plate 33 move backward, and one bobbin holder 4 moves upward, whereby the yarn Y is wound around the bobbin B held by the bobbin holder 4, and the contact roller 5 is Abuts on bobbin B. Note that the position of the yarn placement unit 8 at this time corresponds to the yarn hooking position according to the present invention.

  At this time, as described above, the yarn Y inserted into the yarn insertion gap 34 enters the drop-off prevention gap 35. Therefore, when the yarn placement unit 8 is swung, the yarn Y passes through the drop-off prevention gap 35. The yarn Y does not come out of the yarn insertion gap 34 due to contact with the wall surface of the gap forming portion 33b to be formed. Therefore, the yarn Y can be moved to a position where it can be wound around the bobbin B by swinging the yarn placement unit 8. Accordingly, a mechanism for moving the yarn Y arranged at a position facing the bobbin B to a position where the yarn Y is wound around the bobbin B is separated from a mechanism for arranging the plurality of yarns Y at a position facing the bobbin B. There is no need to provide it, and the configuration of the apparatus is simplified.

  Next, the plurality of yarns Y are moved in the axial direction of the bobbin holder 4 by a yarn gathering device (not shown). Alternatively, in the above state (the state of FIG. 7B), the bobbin holder 4 is rotated and the bobbin B is rotated while traversing the yarn Y in the left-right direction by the traverse guide 6. Then, when the yarn Y comes to a position where it overlaps with a threading slit (not shown) formed on the bobbin B, the thread Y is caught by the slit, and thereby the bobbin B is threaded. When the bobbin B is rotated in this state, the yarn Y is wound around the bobbin B. At this time, the yarn Y is traversed in the left-right direction by the traverse guide 6 and is wound evenly around the bobbin B. At this time, as the amount of the yarn Y wound around the bobbin B increases, the contact roller 5 moves upward.

  When the yarn Y is wound around the bobbin B, the yarn Y is pulled and cut in opposite directions by the bobbin B and the suction nozzle S, and the upstream yarn Y is wound around the bobbin B as described above. The downstream yarn Y is sucked by the suction nozzle S. Thereafter, as shown in FIG. 7C, the fixed plate 32 and the bent plate 33 are retracted backward by further swinging the yarn placement unit 8 clockwise.

  Next, the bobbin replacement operation at full winding will be described. FIG. 11 is a process diagram showing the procedure of the bobbin replacement operation. The replacement of the bobbin B continues the winding of the yarn Y around the bobbin B in the state shown in FIG. 7C, and a predetermined amount of the yarn Y is wound around the bobbin B as shown in FIG. This is done when it is full.

  In order to replace the bobbin B, after the fully wound state shown in FIG. 11A is reached, the bobbin B attached to the lower bobbin holder 4 is rotated and the traverse guide 6 traverses the yarn in the left-right direction. 11B, the contact roller 5 is moved upward, and as shown in FIG. 11B, the turret table 3 is rotated counterclockwise as viewed from the direction of FIG. The bobbin holder 4 holding the full bobbin B that has been moved is moved downward and the other bobbin holder 4 is moved upward. Thereafter, the contact roller 5 is moved downward to contact the new empty bobbin B, and the thread placement unit 8 is swung counterclockwise.

  Then, when the yarn Y comes to a position facing the yarn insertion gap 34, the yarn Y is inserted into the dropout prevention gap 35 through the yarn insertion gap 34, and the inserted yarn Y is bent in the dropout prevention gap 35.

  Next, when the yarn Y is moved in the axial direction of the bobbin holder 4 by a yarn gathering device (not shown), or the yarn Y is traversed in the left-right direction by the traverse guide 6 in the above state (the state of FIG. 11B), As described above, the yarn Y is caught by a not-shown slit for threading of the bobbin B, and the yarn Y is wound around the bobbin B. Further, the yarn Y is cut at a portion in the vicinity of the bent drop-off preventing gap 35 by the force of winding the yarn Y at this time.

  Thereafter, as shown in FIG. 11C, the fixed plate 32 and the bent plate 33 are retracted by swinging the yarn placement unit 8 clockwise as described above. Further, the pusher 7 is moved to the left, thereby pushing out the bobbin B from which the winding of the yarn Y has been completed from the bobbin holder 4 and attaching a new bobbin B to the bobbin holder 4. Then, the yarn Y can be continuously wound around the bobbin B by repeating the operations shown in FIGS. 11 (a) to 11 (c).

  Next, modified examples in which various changes are made to the present embodiment will be described. However, the same components as those in the present embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate.

  In the above-described embodiment, the yarn holding member 13 having the vertical surfaces 13a and 13b is provided as the yarn holding portion according to the present invention, and the yarn Y inserted into the yarn insertion gap 34 has a vertical surface due to its tension. Although it has been configured such that it is sequentially pulled out from the thread holding member 13 by being guided by 13b, it is not limited to this.

  For example, the yarn holding unit may continue to hold the yarn Y such that the vertical surface 13b extends parallel to the front-rear direction. In this case, the yarn holding portion further has a mechanism for removing the yarn Y from the yarn holding member, and after all the yarn Y is inserted into the corresponding yarn insertion gap 34, the yarn holding portion is held by this mechanism. The yarn Y may be removed from the member, or such a mechanism for removing the yarn Y is not provided, and the operator may remove the yarn Y from the yarn holding member.

  Furthermore, the yarn holding unit is not limited to holding the plurality of yarns Y together by the plurality of yarns Y being hung on the connecting portions of the two vertical surfaces 13a and 13b. It may be one having a mechanism for holding the yarns Y together.

  In the above-described embodiment, the yarn holding member 13 is moved using the pusher 7 for pushing out the bobbin B from which the winding of the yarn Y has been completed from the bobbin holder 4, but the present invention is not limited to this. For example, a dedicated mechanism for moving the yarn holding member 13 may be provided. Alternatively, the operator may move the yarn holding member 13 by hand.

  In the above-described embodiment, the right wall surface of the notch 33c is inclined with respect to the direction orthogonal to the longitudinal direction of the gap forming portion 33b. However, the right wall surface of the notch 33c is the gap forming portion. 33b may extend parallel to the direction orthogonal to the longitudinal direction.

  In this case, as described above, there is a possibility that the yarn Y jumps up when the yarn Y comes out of the notch 33c. In such a case, even if such jumping occurs, the yarn Y does not move to a position where it jumps over the corresponding yarn insertion gap 34.

  Further, the thread Y once inserted into the corresponding thread insertion gap 34 does not fall out of the thread insertion gap 34 unless the tension of the yarn Y changes greatly, so that a notch 33c is formed. It does not have to be. In this case, the yarn Y that has entered the non-corresponding yarn insertion gap 34 moves along the right wall surface of the yarn insertion gap 34 instead of moving along the right wall surface of the notch 33c. In this case as well, the yarn Y may jump up as described above.

  In the above-described embodiment, the yarn Y does not fall out of the yarn insertion gap 34 by entering the notch 33c communicating with the yarn insertion gap 34 or the drop-off prevention gap 35. In the present invention, the thread Y is hard to come off by providing a portion where the width of the thread insertion gap 34 becomes narrower from the tip of the gap forming portion 33b to the back of the tip of the thread insertion gap 34. The drop-off prevention unit may be realized by other configurations.

  In the above-described embodiment, the yarn Y inserted into the yarn insertion gap 34 does not fall out of the yarn insertion gap 34 by entering the drop prevention gap 35, and the yarn placement unit 8 swings around the shaft 25 as an axis. By being movable, it is possible to move between a yarn arrangement position for arranging a plurality of yarns Y at positions corresponding to the bobbin B and a yarn hooking position where the yarn Y is wound around the bobbin B. However, it is not limited to this.

  For example, the thread Y inserted into the thread insertion gap 34 is wound around the bobbin B, such as a mechanism for winding the thread Y around the bobbin B by pressing the thread Y inserted into the thread insertion gap 34 toward the bobbin B. A dedicated mechanism may be provided separately. Alternatively, the yarn Y may be arranged at a position where the yarn Y is wound around the bobbin B when the yarn Y is inserted into the yarn insertion gap 34. In these cases, it is not necessary to move the yarn placement unit 8 when the yarn Y inserted into the yarn insertion gap 34 is wound around the bobbin B, so that the yarn Y is prevented from falling off from the yarn insertion gap 34. The drop-off prevention gap 35 is not necessarily provided.

  Further, in the above-described embodiment, the yarn Y bent by contacting the bending plate 33 is not in contact with the tip of the gap forming portion 33b, but the bent yarn Y is not in contact with the tip of the gap forming portion 33b. It may be in contact with. In this case, there is a possibility that the thread Y may be caught on the wall of the thread insertion gap 34 when moving on the thread insertion gap 34 that does not correspond, but if the tension of the thread Y is sufficient, the thread insertion The yarn Y caught on the wall of the gap 34 is detached from the wall of the yarn insertion gap 34 by the tension of the yarn Y.

  In the above-described embodiment, the tip of the gap forming portion 33b is positioned above the bent portion of the bent plate 33 with which the yarn Y contacts in the state where the yarn arranging unit 8 is in the yarn arranging position. However, the present invention is not limited to this, for example, the bent plate such that the fixed plate 32 and the bent plate 33 are positioned upside down in FIG. The tip of the gap forming portion 33 b may be positioned below the bent portion 33. In this case, the yarn Y bent by the bending plate 33 is in an upside-down state in FIG. 9B, and the yarn Y is on the corresponding yarn insertion gap 34 as in the above-described embodiment. The thread Y is inserted into the thread insertion gap 34 only when it arrives.

  Further, in the above-described embodiment, the yarn guide portion according to the present invention is formed by attaching the plurality of bent plates 33 to the fixed plate 32. However, the present invention is not limited to this. It may be integrally formed by one member.
