2. Description of the Related Art Conventionally, the applicant of the present application has developed a Shino exchange machine which automatically performs Shino exchange and Shino succession, and is disclosed in Japanese Patent Laid-Open No. 62-53425. The Shino exchange is constructed as shown in FIG. The Shino exchange 1 is movably arranged beside the spinning machine 2 when the Shino exchange is performed. In the spinning machine 2 shown in the drawing, 3 is a frame of the spinning machine 2, 4 is a roller part, 5 is a trumpet, and 6 is a roving guide. Reference numeral 7 is a creel installed on the frame 3, and is composed of a creel pillar 8, a support bracket 9, a suspension frame 10, bobbin hangers 11 and 12 in the front and rear rows. Reference numeral 13 denotes a spare rail fixed to the support bracket 9, 14 denotes a bobbin carrage movably fitted to the spare rail 13,
15 is a bobbin hanger for shino exchange provided in the bobbin carriage, 16 is a small ball bobbin suspended on the bobbin hanger 11 in the front row (no roving around the bobbin is almost gone), 17 is a bobbin hanger in the back row Medium ball bobbin hung on 12 (no more than half of the roving around the bobbin),
18 is a full bobbin hung on the bobbin hanger 15 (a full bobbin is wound around the bobbin), 19 is a Shino transfer machine that replaces the bobbin hangers 11 and 12 in the front and rear rows, and is distributed to the creel 7. It is movably mounted on the rails 20, 20 that are installed.

Next, in the Shino exchange 1, 21 is a box-shaped Shino exchange body, which is movably supported along the frame 3 by a pair of wheels 22 and a pair of guide rollers 23. Reference numeral 24 denotes a Shino end lead-out device arranged in the Shino exchange main body 21.
In the shin end feeding device 24, 25 is a full bobbin supporting head 25 supported by a supporting device (not shown) so as to be movable up and down and back and forth, and on the upper surface thereof, a lower part of the full bobbin 18 as shown in FIG. A plurality of pegs 26, which fit into the holes and support the full bobbin 18, are rotatably attached at predetermined intervals. The peg 26 is configured to be reversible in the forward and reverse directions by a drive motor (not shown). The full bobbin supporting head 25 is raised from the lowered position shown in FIG. 7 to remove the full bobbin 18 suspended from the bobbin hanger 15 of the spare rail 13 and then lowered to the original position when performing the connecting work. Then, the full bobbin 18 is taken out to the take-out position, and after that, a series of Shino-Join work is completed, and then the bobbin 18 is moved back and forth and up and down for Shino exchange. 27 is an outlet nozzle that is supported by a support device (not shown) so that it can be moved up and down.
27a, and is connected to an air suction source (not shown) via a pipe or valve (not shown). The outlet nozzle 27
When performing the connecting work, as shown in FIG. 8, the full bobbin 18 is lifted from the standby position in FIG. 7 and the suction port 27a is in the take-out position.
It is positioned so as to face the outer peripheral surface of the full bobbin 18 at a position substantially the same as the height of the shino end 18a of the full bobbin 18, and in that state an air suction force is generated in the suction port 27a, so that the shino end 18a of the full bobbin 18 is sucked into the suction port 27a. After sucking to the mouth, it descends to the original standby position. Reference numeral 28 denotes a Shino joint head arranged in the Shino exchange main body 21, which is supported by a supporting device (not shown) so as to be movable back and forth and swingable in a downward state and a lateral direction. 29 is a small bobbin support head that is supported by a support device (not shown) so that it can be moved up and down and back and forth, and like the full bobbin support head 25, it fits in the lower hole of the small bobbin 16 and is the small ball. A plurality of pegs 30 for supporting the bobbin 16 are rotatably attached at predetermined intervals. The small bobbin supporting head 29 is designed to move back and forth and up and down for the shino exchange after the shino joint work is completed when the shino exchange work is performed.

Problems to be Solved by the Invention In the above-mentioned conventional Shino end tapping device 24 in the Shino exchange 1, when the Shino joint work is performed, the pick-up nozzle 27 rises and the suction port 27a of the pick-up nozzle 27 is fully filled at the take-out position. The bobbin 18 is positioned at a lateral position approximately the same height as the shino end 18a, and then the full bobbin 18 is rotated back by rotating the peg 26 and an air suction force is applied to the suction port 27a.
Is sucked into the suction port 27a and discharged, and then the full bobbin 18 is returned as shown in FIG.
27 is lowered to draw out the shino 18b of the full bobbin 18 obliquely downward. As described above, when the sash 18b of the full bobbin 18 is pulled out obliquely downward by the outlet nozzle 27, the sash 18b pulled out from the full bobbin 18 is in contact with the sino winding on the outer circumference of the full bobbin 18, as shown in FIG. As shown, the Shino 28b drawn out from the full bobbin 18 rolls down on the Shino winding on the outer circumference of the full bobbin 18, and the Shino 18b is twisted. The twist is originally false twist, but the end of the shino 18b is the exit nozzle 27 as described above.
Since it is sucked at the suction port 27a and is a free end, the part where the false twist is strongly applied to the shin 18b remains without returning the false twist, and as a result, the shin 18b that is exposed is the shin 18b of the small bobbin 16 thereafter. When the 16b is spliced and supplied to the draft part 4 of the spinning frame 2, a draft defect is likely to occur in the strong twist portion of the slender 18b, and yarn breakage is likely to occur. there were.

Means for Solving the Problems The present invention is intended to solve the above problems, and removes a full bobbin that is suspended from a spare rail in front of the creel on the main body of the Shinogi machine and removes the predetermined bobbin position. The full bobbin supporting head which is rotatably taken out, and the full bobbin taken out to the take-out position is raised to the side position to suck the shino end of the full bobbin to the suction port and then descend to lower the shino. In a Shino end spouting device in a Shino-joint machine, each of which is provided with a pick-up nozzle that is drawn out to a full bobbin at the take-out position by a full-bobbin support head or Shino-Joiner main body It is characterized in that it is provided with a Shino guide for guiding the Shino in a substantially horizontal direction.

Action Take out the full bobbin suspended on the spare rail to the specified take-out position by the full bobbin support head, raise the suction port of the ejection nozzle to the side position of the full bobbin taken out at the take-out position, and set the full bobbin. When the full bobbin is returned and rotated, the shino end of the full bobbin is sucked to the suction port by the air suction force, and then the full bobbin is returned and rotated to lower the outlet nozzle and pull out the shino downward. In this case, the Shino drawn out from the full bobbin is guided in the Shino guide and drawn out in a substantially horizontal direction. Therefore, the Shino is pulled out without rolling on the outer circumference of the full bobbin Shino-maki, and even if there is no strong twist on the exited Shino, it becomes a uniform twist, and the draft is good even if it is spliced and supplied to the draft part. To be done.

It is set so that it can be moved up and down to the guide position shown in FIG. The support mechanism is 32
May be constituted by other means such as a lifting cylinder.

Next, the operation of the Shino exchange 1 having the above configuration will be described.
First, the bobbin suspended from the bobbin hanger 11 in the front row of the spinning frame 2 is the small bobbin 16 and the bobbin hanger 12 in the rear row.
When the bobbin that is hung on the center bobbin 17 becomes a bobbin 17, the Shino exchange 1 is brought into contact with the spinning machine 2 as is well known. By that time, the bobbin hanger is full of bobbins 18 on the spare rail.
Position the bobbin carriage on which is suspended.
When the small bobbin 16 has a small amount of remaining Shino Shin and the Shino exchange machine 1 needs to be replaced, the Shino exchange 1 runs along the spinning machine 2 and stops at a predetermined replacement work position. The full bobbin supporting head 25 rises, and the peg 26 of the full bobbin supporting head 25 is fitted into the lower hole of the corresponding full bobbin 18 suspended on the bobbin hanger of the spare rail to move the full bobbin 18 from the bobbin hanger. Remove. After that, the full bobbin supporting head 25 on which the full bobbin 18 is placed descends to the original lower position as shown by the phantom line in FIG. 1, and the full bobbin 18 descends to the predetermined take-out position shown by the phantom line in FIG. Let On the other hand, as the full bobbin supporting head 25 descends, the ejection nozzle 27 ascends from the standby position to the lateral position of the full bobbin 18 at the ejection position as shown in FIG.
Is at the same height as the Shinobashi 18a of the full bobbin 18
Stops at a position facing the outer peripheral surface of the. The outlet nozzle
27 moves up through the Shinotsu head 28 and Shino guide device Y on the side of the spinning machine 2. After that, the air suction action by the suction port 27a of the dispensing nozzle 27 is started, and the full bobbin supporting head is started.
The peg 26 of 25 rotates in the rewinding direction of Shino to return and rotate the full bobbin 18, and as a result, the Shino end 18a of the full bobbin 18 has the suction port 2
It is sucked by 7a and squeezed out. Thereafter, as shown in FIG. 5 (B), the outlet nozzle 27 descends while continuing the return rotation of the full bobbin 18 and the suction of the suction port 27a, and at the same time, the cylinder 33 of the Shino guide device Y operates to mount the mount 41. Second
In the figure, it moves to the right to raise the upper link 38 of the support mechanism 32 and raise the shino guide 31 from the retracted position to the guide position as shown in FIG. 5 (B). The Shino guide 31 is positioned at the guide position when the suction port 27a of the outlet nozzle 27 is slightly separated from the outer circumference of the full bobbin 18. The shino guide 31 may be raised before the outlet nozzle 27 starts to descend, but in that case, the suction port 27 at the outlet position is arranged so that the shino guide 31 does not interfere with the outlet nozzle 27.
It is necessary to raise it to a position slightly below a. As shown in FIG. 5C, the ejection nozzle 27 descends to the original standby position while continuing the return rotation of the full bobbin 18 and the suction of the suction port 27a, and pulls out the ejected shino 18b from the full bobbin 18.
In that case, the chin 18b pulled out from the full bobbin 27 by the suction port 27a is guided by the chin guide 31 and pulled out in a substantially horizontal direction. Therefore, the shino 18b is pulled out without rolling on the outer periphery of the shinobaki of the full bobbin 18, and a strong twist is not left on the shin 18b that is exposed, and a uniform twist is formed. The shino guide 31 is lowered to the original retracted position by the operation of the cylinder 33 after the outlet nozzle 27 is lowered. The shino 18b pulled out downward by the outlet nozzle 27 is pulled down through the shino guide groove 28a of the shino joint head 28, and is grasped by the shino joint head 28. Thereafter, the Shinobu head 28 swings horizontally as shown by the phantom line in FIG. 1, and the Shino 18b sucked by the suction port 27a at that time is provided in the tip portion of the outlet nozzle 27. It catches on the comb 27b and is cut between the Shinobu head 28 and the outlet nozzle 27 to form a brush-shaped Shino end. Next, the Shinobu head 28 advances to superpose the Shino 18b held in the Shino guide groove 28a with the Shino 16b of the small bobbin 16 being spun above the trumpet 5, and in that state, the Shino 18b is released. To do. As a result, Shino 18b is guided by Shino 16b and Shino 16b
At the same time, it is inserted into the trumpet 5, supplied to the draft part 4, and drafted. In that case, full bobbin 18 Shino
Since the twist is uniform in the 18b as described above, the draft is satisfactorily performed. After that, the Shinotsu head 28 grips the Shino 16b of the small bobbin 16, and the Shino 16b is drafted Part 4
It is cut between and, and Shinotsugi head 28 is returned to the original position. After the completion of the Shino joint, Shino 18 of full bobbin 18
Hang b on the roving guide 6 and set the full bobbin support head 25
The small bobbin support head 30 is operated to suspend the full bobbin 18 on the bobbin hanger 11, and the small bobbin 16 is suspended on the bobbin hanger for the spare rail to perform a shino exchange, but this shino exchange can be performed as is known. It is sufficient, and the detailed description here is omitted.
