DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a Shino exchange machine for replacing a small bobbin in a creel section with a full bobbin in a spare rail section in a spinning machine.

2. Description of the Related Art In the conventional Shino exchange, as shown in JP-A-62-51577, a small plate bobbin exchange head is provided with a lifting plate for lifting the Shino in a vertically swingable manner, and Provide a stroking plate in pressure contact with the outer circumference of the small ball bobbin held by the small ball bobbin replacement head, and when the small ball bobbin replacement head holds the small ball bobbin and moves to the predetermined position, the outer circumference of the small ball bobbin presses the striking plate. At the same time, the lifting plate moves up and hangs down from the small ball bobbin. After cutting, the shin (coarse thread) is lifted to a height near the winding part of the small ball bobbin, and in this state, rotate the small ball bobbin in the shino winding direction. It is designed to wind up Shino.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above conventional Shino exchange, since the lifting plate and the stroking plate are provided separately, the configuration is complicated and the number of parts is large, and it is necessary to adjust the positions of both separately. It was troublesome. An object of the present invention is to solve the above problems.

Means for Solving the Problems In order to solve the above problems, the present invention rotatably mounts an exchange head capable of exchanging a bobbin on an exchange main body that can run along the machine frame of a spinning machine. In a Shino exchange that removes the small bobbin suspended from the creel and hangs it on the bobbin hanger at the spare rail position, replaces the small bobbin standing upright on the replacement head with a bobbin rotating device that can rotate in the Shino winding direction. Comb-like shape that is positioned along the outer circumference of the small bobbin standing upright on the head, extends in the direction opposite to the rotation direction of the small bobbin, and can scoop up the shining hanging from the small bobbin by the rotation of the small bobbin. And a stroking member which elastically contacts the outer periphery of the small ball bobbin and strokes the scooped shino on the outer periphery of the small ball bobbin.

When the small ball bobbin replacement head removes the small ball bobbin that is suspended from the bobbin hanger in the creel and moves it to the specified retracted position, the stroking member contacts the outer peripheral surface of the small ball bobbin and the comb-shaped scooping piece. Is in a state of running near the outer circumference of the small bobbin around the winding part. In this state, the bobbin rotating device operates to rotate the small bobbin in the shino winding direction. As a result, the cut Shino hanging from the small ball bobbin was wound in the state where the height was maintained by entering into the teeth at the corresponding height position of the scooping piece, and the wound Shino was struck by the stroking member. It is sprayed on the outer circumference of the small bobbin.

Examples Hereinafter, examples will be described with reference to the accompanying drawings.
This embodiment is an example in which the Shino exchange 30 running along the front of the spinning machine performs both Shino exchange and Shino splicing. First, the Shino exchange 30
Will be described with reference to FIG. Shino exchange 30 body 31
Is a spout nozzle 35 that spits out the Shino end of the full bobbin 1a and delivers it to the Shinotsu head 33, and the Shino end of the full bobbin 1a is superposed on the Shino R of the small ball bobbin 1c that is being spun and then spun on the small bobbin. 1c

And a full bobbin replacement head 52 and a small ball bobbin exchange head 55 for replacing the full bobbin 1a hanging on the bobbin hanger 24 of the spare rail 15 and the small bobbin 1c hanging on the bobbin hanger 19 of the spinning machine. There is. As shown in FIG. 1, the change bar 60 of the small bobbin exchanging head 55 is pivotally supported by the front side link 62 and the rear side link 63, and although not shown in the drawing, for example, as described in JP-A-60-71724. To Shino exchange 30
The peg 56
While standing upright, it moves back and forth from the retracted position shown by the solid line to the forward position just below the small bobbin 1c shown by the phantom line, and the small bobbin hanging on the front row bobbin hanger 19
It is designed to move up and down by removing 1c and suspending it on the bobbin hanger 24 of the spare rail 15. Further, the full bobbin replacement head 52 is also moved back and forth and up and down by a similar forward and backward movement mechanism, and the respective replacement heads 52 and 55 are moved back and forth from the standby position shown by the solid line in FIG. 1 to the position shown by the phantom line. Thus, a plurality of full bobbins 1a and small bobbins 1c are exchanged at the same time. The details of the construction and operation of the Shino exchange machine 30 are described in detail in "Method of Shino Exchange on a spinning machine" filed on August 31, 1985 by the same applicant as the present applicant. When the Shino-maki bobbin that is hung on the small bobbin becomes a small ball, first, the Shino of the full bobbin 1a to be replaced with the small bobbin 1c is spouted by the spout nozzle 35, and the Shino end of the trumpet 6 is grasped by the Shino joint head 33. After guiding it upward and superimposing it on the Shino R of the small bobbin being spun, the Shino end of the full bobbin 1a is opened, and the Shino of the small bobbin 1c is cut to perform Shino-joint. So small bobbin
Shino S of 1c is hanging from the roving guide 2. In FIG. 6, 3 is a spinning machine base, 4 is a creel pillar of the creel K, 5 is a drafting portion, 8 is a mounting bracket of a supporting rod 9 that supports the roving guide 2, and 10 is a rail for a Shino transfer machine. Shino exchange machine that runs on 11, 12 and replaces the small ball bobbin 1c in the rear row and the middle ball bobbin 1b in the front row, 13 is a support bracket, 14 is a hanging rod, 16 is a carriage bar equipped with a bobbin hanger 24, 25 is a spindle, 28 is a mounting bracket
With the guide rail fixed to the spindle rail 26 by 27, the Shino exchange 30 runs along the front surface of the spinning machine by the wheels 29 on the guide rail 28 and the wheels 31a on the floor.

Next, a processing device 65 for winding and processing the Shino S of the small bobbin 1c will be described with reference to FIGS.

Three pegs 56 are rotatably supported by the change bar 60 of the small bobbin exchanging head 55 at intervals of two spindles of the spinning machine so that they can be rotated in the roving winding direction by the bobbin rotating device 80. . This bobbin rotating device 80
Is a change bar 60 as described in JP-A-60-71724.
A belt 83 is suspended around a pulley 81 of a motor M attached to the peg and a pulley 82 fixed to each peg 56, and three pegs 56 can simultaneously rotate in the winding direction of the roving (clockwise in the figure). It is configured as follows. A beam 67 is fixed to the rear wall of the main body 31, and a change bar is attached to the beam 67.
Brackets 69 are fixed by bolts 70 so as to correspond to the respective pegs 56 when 60 is in the standby position shown by the solid line in the figure. An L-shaped arm 72 is rotatably supported by a pin 73 at the tip of the bracket 69, and a spring 74 is stretched between the arm 72 and the bracket 69 so that the stopper 72a abuts the bracket 69. It is always urged forward. A processing head 76 is attached to the tip of the arm 72. As shown in FIGS. 4 and 5, the processing head 76 is located on the left side of the bent substrate 77, that is, in the direction of arrow rotation of the small bobbin 1c held by the small bobbin exchange head 55 moved to a predetermined position. In this way, the comb-shaped scooping pieces 78 are formed at predetermined intervals, and the tips of the scooping pieces 78 are obliquely cut off so that the intervals between the scooping pieces 78 are rough. It is a guide path 90 for the thread S. Each scooping piece 78 is a small bobbin at the predetermined position as shown in FIG.
It extends in the direction opposite to the rotation direction of the small bobbin 1c along the outer circumference of 1c, and when it comes into contact with the small bobbin 1c, a small gap indicated by α occurs between the tip and the small bobbin 1c. I try not to contact him. The opposite side of the above-mentioned scooping piece 78 is bent in an arc shape to form a stroking member 92, and a concave portion 94 is formed between the stroking member 92 and the scooping piece 78, and configured as described above. The processing head 76 is mounted so that the mounting height of the processing head 76 substantially corresponds to the vicinity of the winding start portion of the small bobbin 1c.

 The operation will be described below.

When the Shinanomaki bobbin hanging on the front row bobbin hanger 19 of the spinning machine becomes the small bobbin 1c, the full bobbin exchange head 52 rises and the full bobbin 1a hanging on the spare rail 15 is placed on the peg. As shown in Fig. 1, when the Shino end of the full bobbin 1a is exposed and the Shinotsu head 33 is used to make Shino-joint with Shino R of the small bobbin being spun, the Shinobu of the small bobbin being spun is separated. The bobbin Shino S hangs down from the roving guide 2. After advancing the small ball bobbin exchange head 55 and mounting the small ball bobbin 1c that is raised at the forward end and is hung on the bobbin hanger 19 on the peg 56 (state of phantom line in FIG. 1), the small ball bobbin exchange head 55 is retracted. When it is returned to the predetermined retracted position (solid line state), the processing head 76 is retracted from the phantom line position in the figure to the solid line position by pressing the small bobbin 1c as shown in FIG. 74 Force makes contact with the small bobbin 1c that is standing. In this state, the motor M attached to the change bar 60 is rotated to rotate the shin S of the small bobbin 1c mounted on the peg 56 in the winding direction and wind it around the outer circumference of the small bobbin 1c. At this time, since the contact of the processing head 76 with the small bobbin 1c is due to the force of the spring 74, by setting the spring 74 force to the desired optimum value, a light and elastic contact pressure can be obtained, and the processing head 76 is Since only a part of the scooping piece 78 and the stroking member 92 are in contact with the small bobbin 1c, the contact area is small.
Even if the 1c rotates, the Shino S does not scatter, and there is a gap α between the tip of the scooping piece 78 and the small bobbin 1c, so the tip may be stuck on the rotating small bobbin 1c. It rotates smoothly. Shino S, which hangs down when the small bobbin 1c rotates, is released from the small bobbin 1c so as to form a balloon by centrifugal force as shown by the phantom line SA in FIG. 4, and rotates to the processing head 76 in this state. When Shino S comes,
Any one of the plurality of scooping pieces 78 scoops up at a position extremely close to the free point P, is pulled up by the pulling surface 79 at the tip and is guided to the guide path 90, and thereafter Shino S is guided to the guide path 90. Then, it is wound in an orderly manner, and then it is stroked by the stroked surface 92 to surely adhere to the small bobbin 1c, and unwinding thereafter is completely prevented. As described above, the treatment of the roving yarn end by the treatment head 76 shown in this embodiment is performed by a plurality of scooping pieces 78.
By any one of the above, Shino S is separated from the small bobbin 1c and scooped up at a position extremely close to the separation point P (may be coincident), pulled up on the pulling surface 79 and guided to the guide path 90 and wound up. Therefore, the wound Shino S is wound in a layered manner. Full bobbin 1a placed on full bobbin replacement head 52 after winding Shino S of small bobbin 1c (or during winding)
Is hung on the bobbin hanger 19.
1c spare rail 15 carriage bar 16 bobbin hanger
It is exchanged by hanging it on 24. As described above, the Shino S of the small ball bobbin 1c inserted into the carriage bar 16 surely adheres to the small ball bobbin 1c. Therefore, when the small ball bobbin 1c is subsequently transferred to the roving stripper position, it is unwound again. Without this, problems such as induction of yarn breakage and fiber scattering in the spinning machine are eliminated.

In the above embodiment, the case of combining Shino exchange and Shino joint, that is, the case where the remaining Shinobu of the small bobbin 1c hangs above the trumpet 6, but when only Shino exchange is performed, the small bobbin changing head 55 is used. Since the Shino R being spun is pulled between the small bobbin 1c and the roving guide 2 while the small bobbin 1c is placed and retracted, the Shino is usually cut during this time. Zanshino cut during retreat is a small bobbin replacement head
When 55 returns to the retracted position, it is wound in the same manner as above.

Next, a second embodiment shown in FIGS. 7 and 8 will be described. A rod 101 is provided so as to project from the rear side of the change bar 60, and an abutment block 103 that abuts against the wall surface 31b of the main body 31 is fitted into the rod 101 to prevent it from coming off 105 and preventing it from rotating. A spring 107 is stretched between the change bar 60 and the contact block 103 so that the contact block 103 is usually kept away from the change bar 60. A processing head is mounted on the upper surface of the contact block 103 via a bracket 109.
111 is attached, the processing head 111 is made of an elastic material such as rubber, and the interval between the opening ends thereof is wider than the outer diameter of the small bobbin 1c, and the comb tooth-shaped scooping piece 78e and the stroking member. 9
Equipped with 2e. The processing head 111 has substantially the same construction as that of the above embodiment except that the scooping piece 78e and the stroking member 92e are elastically deformable as shown by the solid line in FIG. The processing apparatus configured as described above pegs the small bobbin 1c.
After mounting on 56 (state of phantom line) small bobbin replacement head
As 55 moves backward, the contact block 103 is received by the receiving portion 3 of the main body 31.
1b and then only rod 101 moves against the force of spring 107 to return to the retracted position, processing head 11 as described above.
1 comes into contact with the small bobbin 1c, and then the peg 56 is rotated in the sino-winding direction and wound and stroked in the same manner as in the above embodiment.

In the present application, the processing head 111 of the second embodiment may be used instead of the processing head 76 of the first embodiment,
In that case, the arm 72 can be integrated with the bracket 69. Further, the arm 72, the processing head 76, and the spring 74 of the first embodiment may be provided on the bracket 109 of the second embodiment.

Advantageous Effect of the Invention In the present invention, the stroking member is brought into contact with the outer circumference of the small ball bobbin and the comb tooth-shaped scooping piece is arranged along the outer circumference of the small ball bobbin, and in this state, the small ball bobbin is rotated in the shino winding direction. Since the sash is wound, the sash after cutting can be completely wound around the outer periphery of the small ball bobbin and pressed, and the sash can be prevented from being unwound during the transportation of the small ball bobbin. Also, since the Shino is pulled up to the winding part by the comb-shaped scooping piece along the outer circumference of the small bobbin, the scooping piece can be provided integrally with the stroking member to make a simple structure. It is possible to reduce the number of points and simplify maintenance.
