  By the way, the bobbin transport device employs a plate-shaped transfer rail as a transfer means for transferring a locking member that can be engaged and disengaged to the engagement recess of the peg tray, and the transfer rail is reciprocated by a drive means such as an air cylinder. In some cases, the locking member is moved. However, when the transfer rail is adopted as the transfer means, if the transfer rail is bent in a meandering manner, the shift causes a displacement in the locking position where the locking member is locked in the engaging recess of the peg tray. That is, in the bobbin conveying device, when the locking member and the peg tray are engaged and the peg tray is pushed out in the traveling direction, it is preferable to apply the pushing force applied from the locking member to the peg tray along the traveling direction of the peg tray. For this reason, when the transfer rail is adopted as the transfer means and the transfer rail is bent, the locking position of the locking member with respect to the engaging recess of the peg tray is displaced, and as a result, the pushing force of the locking member is advanced by the peg tray. There is a risk of not being added along the direction.

  The present invention has been made paying attention to such problems existing in the prior art, and its purpose is to prevent the displacement of the locking position between the peg tray and the locking member due to the bending of the transfer rail. It is an object of the present invention to provide a bobbin conveying device that can perform the above.

  In order to solve the above problems, the invention according to claim 1 is provided with a peg tray passage for guiding movement in a single row of peg trays having a peg for inserting a bobbin on the upper surface and a locking recess on the lower surface. A tray guide member, a transfer rail that is reciprocally movable along the peg tray path below the peg tray row and is not movable up and down, drive means for reciprocating the transfer rail, and The transfer rail is configured to be displaceable at a locking position for locking the peg tray to prevent movement of the peg tray during forward movement and to a retracted position for allowing passage of the peg tray during backward movement. A locking member disposed on the transfer rail and disposed on the transfer rail to guide reciprocal movement of the transfer rail along the peg tray path A guide member disposed below the peg tray passage and supporting the guide member so as to be slidable along the peg tray passage, and the guide member is disposed at a location corresponding to the locking member. The gist of this is that

  According to this, the guide member is disposed near the peg tray and the locking member. For this reason, the transfer rail does not bend in a meandering manner at the locking position between the peg tray and the locking member, and the locking position of the locking member with respect to the peg tray can be favorably maintained. Therefore, it is possible to prevent the displacement of the locking position between the peg tray and the locking member due to the bending of the transfer rail. And even if it is a case where a transfer rail bends in a meandering shape, it becomes possible to apply the pushing force of the peg tray by a locking member along the transfer direction of a peg tray. In the present invention, the “location corresponding to the locking member” means a location where at least a part thereof overlaps with the arrangement length of the locking member in the longitudinal direction of the transfer rail.

  According to a second aspect of the present invention, in the bobbin conveying device in the spinning machine according to the first aspect, the locking member is provided to be rotatable with respect to the transfer rail, and the guide member is The gist is that it is arranged on the rotation axis of the locking member.

According to this, since the locking member and the guide member can be attached to the transfer rail in the same work process, the work efficiency related to the attachment can be improved.
According to a third aspect of the present invention, in the bobbin conveying device according to the first or second aspect, the guide member includes a restriction that restricts displacement movement of the locking member at the locking position and the retracted position. The gist is that the section is provided.

  According to this, the displacement movement amount of the locking member during the reciprocating movement of the transfer rail can be restricted, and the locking member can be reliably displaced between the locking position and the retracted position. That is, in the bobbin transport device that repeatedly transports the peg tray, the restoring position of the operating position of the locking member can be improved.

  According to a fourth aspect of the present invention, in the bobbin transport device according to any one of the first to third aspects, the locking member is disposed so as to be independently displaceable with the transfer rail interposed therebetween. It consists of a pair of locking claws.

  According to this, since the locking member is a pair of locking claws that can be displaced independently, even if, for example, a thread or fiber is wound around the locking claw on one side, A peg tray can be sent by one latching claw functioning.

  Invention of Claim 5 is a bobbin conveying apparatus as described in any one of Claims 1-4. WHEREIN: The said tray guide member is the said peg tray channel | path which can guide the bottom face and side surface of the said peg tray. And a lower extension that extends in the vertical direction of the passage and is disposed on both sides of the transfer rail, and the guide member includes the transfer rail and the lower extension. It is arranged between the two, the sliding rail is in sliding contact with the inner surface of the lower extension when the transfer rail reciprocates, and the lower extension of the tray guide member is also used as the support means.

  According to this, since the member constituting the peg tray passage and the support member supporting the guide member can be integrated, the number of parts can be increased compared to the case where the member constituting the peg tray passage and the support member are provided separately. Simplification of the bobbin conveying device by reduction is realized, and an increase in manufacturing cost can be suppressed.

As a result, the locking claws 15 and 16 are supported by the support protrusions 13b and 14b of the rail guides 13 and 14, and the locking ends, i.e., the first ends 15c and 16c are located on the transfer rail 10 by their own weight. It is biased in a direction protruding from the upper surface.

  Further, the locking claws 15 and 16 are formed with notches 15e and 16e between the fitting portions 15b and 16b and the second ends 15d and 16d, respectively. Then, the locking claw 15 is held in the locked position when the boss 13d of the rail guide 13 abuts against the notch 15e at the locked position. Similarly, the locking claw 16 is held in the locked position by the rotation of the rail guide 14 being restricted by the boss 14c of the rail guide 14 coming into contact with the notch 16e at the locked position. . When the locking claws 15 and 16 are held in the locked position, the first end portions 15 c and 16 c protrude from the upper surface of the transfer rail 10. On the other hand, the locking claw 15 is restricted from rotating by the lower surface on the first end portion 15c side coming into contact with the boss 13c of the rail guide 13 in the retracted position, so that the upper surface thereof is along the upper surface of the transfer rail 10. That is, the upper surface of the locking claw 15 is held in a substantially horizontal state (see FIG. 4B). Similarly, the locking claw 16 is restricted from rotating when the lower surface on the first end portion 16 c side abuts on the boss 13 d of the rail guide 14 at the retracted position, and the upper surface thereof is along the upper surface of the transfer rail 10. That is, the upper surface of the locking claw 16 is held in a substantially horizontal state. In the present embodiment, the bosses 13c, 13d, 14c, and 14d of the rail guides 13 and 14 function as a restricting portion that restricts the displacement (rotation amount) of the locking claws 15 and 16.

  In the transfer rail 10, bolt holes 10 b through which the bolts B are inserted are formed at positions corresponding to the bolt holes 13 a and 14 a of the rail guides 13 and 14 at the locations where the rail guides 13 and 14 are disposed. Further, in the transfer rail 10, the boss hole 10c for inserting the boss 13c of the rail guide 13 and the boss 14d of the rail guide 14 and the boss 13d of the rail guide 13 and the boss 14c of the rail guide 14 are inserted on both sides of the bolt hole 10b. A boss hole 10d is formed.

  For this reason, the rail guide 13 supporting the locking claw 15 with the support convex portion 13 b inserts one boss 13 c into one boss hole 10 c of the transfer rail 10 and the other boss 13 d to the other of the transfer rail 10. By being inserted into the boss hole 10d, the transfer rail 10 is positioned on one side. In addition, the rail guide 14 that supports the locking claw 16 with the support convex portion 14 b inserts one boss 14 d into one boss hole 10 c of the transfer rail 10 and the other boss 14 c as the other boss of the transfer rail 10. By being inserted into the hole 10d, the transfer rail 10 is positioned on one side opposite to the rail guide 13. The rail guides 13 and 14 are fixed to the transfer rail 10 by inserting the bolts B into the bolt holes 10b, 13a and 14a and fastening the bolts B and nuts N, respectively.

  The rail guides 13 and 14 and the locking claws 15 and 16 fixed to the transfer rail 10 move in accordance with the reciprocating movement of the transfer rail 10. The transfer rail 10 is guided to reciprocate along the peg tray path 5c when the rail guides 13 and 14 are brought into sliding contact with the straight portions 5a2 and 5b2 of the tray guide members 5a and 5b. The locking claws 15 and 16 rotate about the axis of the fixing bolt B as the rotation center, and the rail guides 13 and 14 are on the rotation centers of the locking claws 15 and 16 (on the rotation axis). It is arranged. Thereby, the rail guides 13 and 14 are located at positions corresponding to the locking positions where the locking claws 15 and 16 are locked to the locking recesses Pb of the peg tray P, that is, in the vicinity of the locking positions of the locking claws 15 and 16. Will be placed.

  The spinning machine is provided with a known all-simultaneous mass transfer device 22 equipped with a bobbin catcher 21 that is moved up and down via a pantograph mechanism 20 by the action of a drive rod 19 reciprocated by a power cylinder 18. It is installed.

Next, the operation of the bobbin transport device T configured as described above will be described.
When the machine base 1 of the spinning machine stops full, a pipe changing operation is performed in which the empty bobbin E on the peg tray P and the full bobbin F on the spindle 2 are exchanged via the intermediate peg 3 by the pipe changing device 22. When the replacement work is completed, the full bobbin F can be carried out and the empty bobbin E can be supplied. When a full bobbin supply signal is issued from the winder, the unloading of the full bobbin F from the machine base 1 of the spinning machine and the carry-in of the empty bobbin E to the machine base 1 are started.

  In the state where the transfer rail 10 is arranged at the reference position, the leading ends (first end portions 15c, 16c) of the locking claws 15, 16 are placed in the locking recesses Pb of the peg tray P as shown in FIG. While entering, it is locked to the wall surface of the locking recess Pb. When the air cylinder 11 is immersed from this state and the transfer rail 10 moves forward, that is, moves in the direction indicated by the arrow A shown in FIG. 4A, the locking claws 15 and 16 are moved in accordance with the forward movement of the transfer rail 10. The tip pushes the peg tray P in the transfer direction (arrow A direction), and the peg tray P is transferred. At this time, in the bobbin transport device T of the present embodiment, since the transfer rail 10 is guided by the rail guides 13 and 14, the locking positions of the locking claws 15 and 16 corresponding to the locking recesses Pb are constant. When the transfer rail 10 moves forward, the force that the locking claws 15 and 16 push out the locking recess Pb is always applied to a fixed portion (the central portion of the peg tray P). That is, the pushing force is applied along the transfer direction of the peg tray P.

  Thereafter, when the air cylinder 11 is protruded and the transfer rail 10 moves backward to the reference position, that is, moves in the direction indicated by the arrow B shown in FIG. 4B, the locking claws 15, The tip of 16 is detached from the wall surface of the locking recess Pb. Then, when the backward movement of the transfer rail 10 further proceeds, the anti-clockwise rotation in FIG. 4B is performed so that the leading ends of the locking claws 15 and 16 go under the peg tray P as shown in FIG. Rotate in the direction. At this time, the amount of rotation of the locking claws 15, 16 is regulated by the tips of the locking claws 15, 16 coming into contact with the bosses 13 c, 14 d of the rail guides 13, 14. When the locking claws 15 and 16 are rotated counterclockwise, the notches 15e and 16e of the locking claws 15 and 16 and the bosses 13d and 14c of the rail guides 13 and 14 are engaged. The state is released.

  After that, as shown in FIG. 4 (c), the locking claws 15 and 16 are moved backward by the transfer rail 10, so that the peg tray P (FIG. 4 (c)) following the previously locked peg tray P is moved. ) Is locked to the wall surface of the locking recess Pb indicated by “P1” in FIG. At this time, the locking claws 15 and 16 are rotated in the clockwise direction in FIG. 4C by their own weight so as to enter the locking recess Pb of the peg tray P. The amount of rotation of the locking claws 15 and 16 rotated clockwise is that the bosses 13d and 14c of the rail guides 13 and 14 are engaged with the notches 15e and 16e of the locking claws 15 and 16, respectively. Regulated by.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) The rail guides 13 and 14 are arranged at positions corresponding to the locking claws 15 and 16, that is, at least a part of the rail guides 13 and 14 in the longitudinal direction of the transfer rail 10. (The length from the end portions 15c and 16c to the second end portions 15d and 16d). According to this, the rail guides 13 and 14 are disposed near the locking positions of the peg tray P and the locking claws 15 and 16. Therefore, the transfer rail 10 does not bend in a meandering manner at the locking position of the peg tray P and the locking claws 15 and 16, and the locking position of the locking claws 15 and 16 with respect to the peg tray P can be maintained well. it can. That is, the central portion of the peg tray P can be pushed by the locking claws 15 and 16. Accordingly, it is possible to prevent the displacement of the locking positions of the peg tray P and the locking claws 15 and 16 due to the bending of the transfer rail 10.

  (2) When the rail guides 13 and 14 are arranged apart from the locking claws 15 and 16, the transfer rail 10 bends in a meandering manner at the locking position of the peg tray P and the locking claws 15 and 16, and is locked. The locking positions of the claws 15 and 16 are disengaged from the central portion of the peg tray P. In such a case, the pushing force by the locking claw is not applied along the transfer direction of the peg tray P, and the pushing force is applied to the peg tray P from a biased direction. As a result, a state where the peg tray P is fed in contact with the side wall 5c2 on one side of the peg tray passage 5c occurs, which causes wear of the tray rail 5 and the peg tray P. Therefore, in this embodiment, the rail guides 13 and 14 are disposed near the locking positions of the locking claws 15 and 16, and the locking positions of the locking claws 15 and 16 with respect to the peg tray P are favorably maintained, and the pushing force is increased. Is added along the transfer direction of the peg tray P, the wear of the tray rail 5 and the peg tray P cannot occur. Further, an increase in load related to the transfer of the peg tray P is not caused.

  (3) The rail guides 13 and 14 are arranged on the rotation axes of the locking claws 15 and 16. According to this, since the latching claws 15 and 16 and the rail guides 13 and 14 can be attached to the transfer rail 10 in the same work process, the work efficiency related to the attachment can be improved. That is, the rail guides 13 and 14 and the locking claws 15 and 16 can be attached to the transfer rail 10 by the bolt B.

  (4) The rail guides 13 and 14 are provided with bosses 13c, 13d, 14c and 14d for restricting the amount of displacement (rotation amount) of the locking claws 15 and 16 at the locking position and the retracted position. According to this, the displacement amount (rotation amount) of the locking claws 15 and 16 during the reciprocating movement of the transfer rail 10 can be restricted, and the locking claws 15 and 16 are moved between the locking position and the retracted position. It can be displaced reliably. In other words, in the bobbin transport device T that repeatedly transports the peg tray P, it is possible to improve the recoverability of the operating positions of the locking claws 15 and 16.

  (5) The transfer rail 10 is provided with a pair of locking claws 15 and 16 that can be displaced independently. According to this, for example, even if a thread or fiber is wound around one locking claw and the locking claw stops operating, the other locking claw can function to feed the peg tray P. That is, even when a thread or fiber is wound around the locking claw, it is not necessary to immediately stop the operation of the bobbin transport device T, and the time (frequency) for stopping the operation can be reduced.

  (6) The straight portions 5a2 and 5b2 are formed on the tray guide members 5a and 5b, and the rail guides 13 and 14 are supported by the straight portions 5a2 and 5b2. For this reason, it is not necessary to provide a member for supporting the rail guides 13 and 14 separately from the tray rail 5, and the number of parts can be reduced as compared with the case where the members for supporting the tray rail 5 and the rail guides 13 and 14 are provided separately. Simplification of the bobbin transport device T can be realized, and an increase in manufacturing cost can be suppressed.

In addition, you may change the said embodiment as follows.
In embodiment, you may change the structure of the rail guides 13 and 14 and the latching claws 15 and 16 as shown to Fig.5 (a), (b). In the rail guides 13 and 14 shown in FIGS. 5A and 5B, metal pins K are inserted in place of the bosses 13d and 14c described in the embodiment. The pin K is inserted into insertion holes 23a and 23b formed in the rail guides 13 and 14, respectively. The locking claws 15 and 16 are formed with long holes 24a and 24b through which the pin K is inserted instead of the notches 15e and 16e described in the embodiment. As a result, the rail guides 13 and 14 are positioned on the transfer rail 10 by inserting the pins K through the insertion holes 23a and 23b, the long holes 24a and 24b, and the boss hole 10d, and are fixed by the bolts B as in the embodiment. According to this configuration, the amount of rotation of the locking claws 15 and 16 is regulated by the contact between the long holes 24a and 24b formed in the metal locking claws 15 and 16 and the metal pin K. Become.
