Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for connecting threads in a spinning machine. More specifically, when a spinning bobbin suspended from a bobbin hanger in a spinning machine becomes a small bobbin, the thread of the full bobbin to be replaced with the thread of the small bobbin is connected to the thread of the small bobbin. Regarding the method.

[Conventional technology and its problems] When the Shinomaki bobbin hanging from the bobbin hanger of a spinning machine becomes empty or becomes a small bobbin, replace the Shinomaki bobbin with a full bobbin, It is necessary to join the thread of the small bobbin to the thread of the small bobbin, or to insert the thread of the full bobbin into the drafting section of the spinning frame.

However, as is well known, the shin of the Shinomaki bobbin is fluffy due to a slight twist, so the shin will break just by pulling it lightly. Because it is difficult to mechanically splice such weak wires, conventionally, as disclosed in Japanese Patent Laid-Open No. 60-71724, spinning machines are connected by a wire exchanger that runs along the frame of the spinning machine. The automated work was limited to replacing the small bobbin attached to the bobbin hanger and the full bobbin attached to the bobbin hanger on the spare rail, and the splicing work had to be done manually.

[Means for solving problems]

Therefore, the present invention aims to provide a method for spinning machines that can automate the work, which was previously thought to be impossible. When the Shinomaki bobbin currently in use becomes small balls, first take out the Shino of the full bobbin to be replaced with the small bobbin, grasp the end of the Shino and guide it above the trumpet, and polymerize it into the Shino of the small bobbin being spun. After that, the grip on the shin end of the full bobbin is released, and the shin of the small bobbin is cut to perform the shin joint.

〔Example〕

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

In the spinning machine according to this embodiment, when the Shinomaki bobbin attached to the bobbin hanger arranged along the spindle row of the spinning machine becomes a small bobbin, the small bobbin is transferred to the front row of the creel of the spinning machine. This is done when replacing a full bobbin suspended from a spare bobbin hanger supported by a spare rail placed above the front of the bobbin hanger. Therefore, the Shino transfer work is a part of the Shino replacement work in a broad sense, and the Shino replacement work in a broad sense is the replacement work of a full bobbin and a small bobbin, the work of replacing the Shino of a small bobbin with a Shino during spinning of a full bobbin, Furthermore, hooking a full bobbin to the roving guide related to the above-mentioned work includes work and the like.

The Shino exchange work in a broad sense is performed using a Shino exchange machine 50 shown in FIG. 1 (front view) and FIG. 2 (side view). As shown in FIG. 3, the Shino exchanger 50 is disposed on both sides of the frame of the spinning machine so as to be movable along the spindle row of the spinning machine.

As shown in Fig. 3, creel pillars 4 of the spinning creel are placed at appropriate intervals in the longitudinal direction of the spinning machine in the center of the spinning frame 3.

Bobbin hangers 19 and 20 are supported. A small bobbin IC and a medium bobbin 1b are suspended from these bobbin hangers 19 and 20. These front and rear rails 11, 12 bobbin hangers 19, 2
As shown in FIG. 4 as the positions of the small bobbin IC and the medium bobbin 1b, the small bobbin IC and the medium bobbin 1b are arranged so as to face each other every two pitches of the drafting section 5, that is, every two spindle pitches. One bobbin hanger on this front rail 11 is connected to the front row bobbin hanger 19 and the bobbin hanger 20 on the rear rail 12.
is referred to as a rear row bobbin hanger 20.

As shown in FIG. 3, a substantially ring-shaped roving guide 2 is supported by a support rod 9 on a creel pillar 4 below the middle of the front and rear bobbin hangers 19 and 20. As shown in FIG. 18(A), this roving guide 2 is made into a ring shape having an opening 2C.
A protrusion 2a protrudes inwardly on the side opposite C, and claws 2b protrude upward as shown in FIG. 18(B) on both sides in contact with the opening 2C. This claw part 2b
may be provided so as to protrude inward. The raised portion 2a serves to separate the wire supplied from the front row bobbin 1c and the rear row bobbin 1b, and the claw portion 2b serves to hang the wire of the full bobbin after the wire is spliced to the roving guide 2. useful for.

Above the front row bobbin hanger 19, a spare rail 15 attached to the tip of the support bracket 13 is disposed along the longitudinal direction of the machine. The preliminary rail 15 is formed into a hollow columnar body with an open bottom in cross section, and the bobbin carrier nozzle 17 is inserted into and out of the open end of the column, and is movable along the preliminary rail 15.

The bobbin carrier body 17 has a spare bobbin hanger 24, as shown in FIG. You can cross paths.

As shown in FIG. 3, the shading work accompanied by shin splicing is performed between the small bobbin 1c of the front row bobbin hanger 19 and the full bobbin 1a of the spare bobbin hanger 15. After finishing the thread drafting work, the thread R of the full bobbin 1a of the front row bobbin hanger 19 is supplied to the bank roller 5a of the drafting section 5 via the roving guide 2 and the trumpet 6, where it is heated by the spindle 25 and formed into yarn. As yarn spinning progresses, the full bobbin 1a of the front row bobbin hanger 19 consumes its grain and becomes a medium-sized bobbin, while the grain of the medium-sized bobbin 1b of the rear row bobbin hanger 20 also consumes its grain and becomes a small-ball bobbin.

At that time, the front row bobbin hanger 19 and the rear row bobbin hanger 20 are replaced using the Shino shunter 10 shown in FIG.
Arrange the bobbin as shown in the figure, and then perform the thread exchange again with the thread joint. The above Shino replacement is for each bobbin hanger 1.
After removing 9 and 20 from the respective rails u and 12, 18
This is achieved by turning 0°. Its detailed structure is disclosed in Japanese Patent Publication No. 60-1484 by the same applicant as the present invention.
This is disclosed in Japanese Patent No. 8, and since the Shino replacement work is not a main part of the present invention, a detailed explanation thereof will be omitted. On the other hand, the supply of a full bobbin to the spare bobbin hanger 24 is accomplished by inserting the full bobbin at the roving machine position and moving it together with the carriage bar 17 to a predetermined position on the spare rail 15 of the spinning machine.

As described above, the Shino changer 50 is movable along the front face of the spinning frame, that is, along the row of spindles 25. As shown in FIGS. 1 to 3, the lower side of the main body 51 of the Shino exchanger 50 includes a heavy wheel 51a, a guide roller 29 on the side of the main body 51 facing the spinning machine, and a running motor 21 inside the main body 51. and a traveling motor 21 and a scroll cam 22 that moves with it.

A guide rail 28 is attached via a mounting bracket 27, and a large number of guide bins 30 are installed on the outside of the guide rail 28 (11, 11i surfaces at intervals equal to the pitch interval of the front row bobbin hanger 19). The guide 1 coke 29 is rotatable on the guide rail 28, and therefore, by rotating the scroll cam 22 while engaging the guide bin 30 with the scroll cam 22, the shino exchanger 50 can be rotated on the spindle of a spinning frame. It can be moved along the row and stopped at a predetermined position.

Next, the configuration of the Shino switch 50 will be explained. Shino exchange a5

The small bobbin exchange head 55, which moves up and down as well as moves back and forth, and rotatably supports three banks, is connected to the proar 23 housed in the Shino exchanger main body 51 via a hose 23a, and has its suction action. 6 nozzles 62 for pulling out the thin end of a full bobbin, six connecting heads 60 for superimposing the thin end of the full bobbin on the thin end of the small bobbin being spun, and a roving guide 2 for pulling out the thin end of the full bobbin. A plate 58 and drive means for moving each of the members in a predetermined cycle are provided for the plate 58. From Figure 1 below,
The respective constituent elements will be explained with reference to FIG.

First, the full bobbin exchange head 52 will be explained.

The change par 71 of this full bobbin exchange head 52 has 6
Full bobbin exchange head pegs 53 are rotatably arranged (FIG. 11). Using the peg 53, the third
In order to move the full bobbin 1a at the position shown in the figure to the position of the small bobbin IC, it is necessary to move the bed 53 up and down and forward. As shown in FIG. 5, the changer 71 on which six bets 53 are arranged is connected to the full bobbin exchange head lifting/lowering mechanism shown in FIG. 31 is arranged on the upper part of the elevating body 37. Two vertically parallel chains 36a, 36b are connected to the elevating body 37, and these chains 36a, 36b are connected to the Shino exchanger 5.
The elevating body 37 is moved up and down by moving the gutter elevating mechanism motor 32 both up and down to replace the full bobbin disposed in the bobbin. That is, a chain wheel 33a is attached to the shaft 33 of the motor 32, and the rotation of the chain wheel 33a is transmitted to the shaft 34 rotatably supported on the main body 51 of the Shino exchanger 50 via the chain 33b and chain wheel 34a. Ru. Chain wheels 35a, 35b are attached to both ends of the shaft 34, and one end of the aforementioned chains 36a, 36b hung on the chain wheels 35a, 35b is directly connected to the lower part of the elevating body 37, and the other end is connected to the lower part of the main body 51. A chain wheel 39a is rotatably disposed upward.

It is connected to the upper part of the elevating body 37 via the shaft 39b, so that the vertical movement of the elevating body 37 is achieved by rotation of the shaft 34. At this time, since the elevating body 37 is slidably fitted into guide members 38a and 38b provided perpendicularly to the main body 51, accurate movement in the vertical direction is ensured. Next, the full bobbin exchange head 52 is moved back and forth by a full bobbin exchange head back and forth movement mechanism shown in FIG. A housing 77 is provided above the elevating body 37, and the rotation of a motor 86 inside the housing 77 swings the arm 82 through a reducer 85, gears 84, 83, and the swinging motion is produced by a motor 86 provided at the tip of the arm 82. The sliding pin 81 is connected to the swinging arm 80 through the elongated hole 80a of the swinging arm 80 with which the sliding pin 81 engages.
can be conveyed to. A lower end of the outer link 76 and a swing arm 80 are fixed to a pin 79 which is pivotally connected to the housing 77 . Thereby, the reciprocating rotational movement of drive gear 84 in the direction of the arrow causes a swinging movement of swing arm 80 and outer link 76 in the direction of the arrow. A pivot pin 7 is provided at the upper end of the outer link 76.
4, one end of the change bar support member 72 is connected to the other end of the support member 72, and a change bar 71 is fixed to the other end of the support member 72. On the other hand, a pivot pin 73 is provided at the middle portion of the chain bar support member 72, and the upper end of the inner link 75 is connected via this pivot pin 73. The lower end of inner link 75 is connected to housing 77 via a pivot pin. Therefore, by the swinging motion of the outer link 76 in the direction of the arrow, the bet 53 on the change half 1 is moved back and forth with respect to the spinning machine while maintaining its vertical position, and is moved to a position directly below the spare bobbin hanger 24 and the front row bobbin hanger. It can be moved to a position directly below No. 19.

Next, the full bobbin peg 53 in the full bobbin exchange head 52 and its rotation mechanism will be explained with reference to FIGS. 10 to 13. As shown in FIGS. 1 and 11, the change half 1 of the full bobbin exchange head 52 has six pegs 53 (53a, 53
b, 53c, 53d, 53e.

53f) is provided. These pegs 53 are adapted to be rotated in order to unwind or wind up the wire from a full bobbin during the steps of the wire exchange, as will be explained in detail below regarding the operation of the wire exchange. Furthermore, at the beginning of the replacement operation, every other peg 53 can be rotated 180 degrees with respect to the other pegs 53, as shown in FIG. The reason for this is, as will be described below, to ensure that the tip of the full bobbin in this embodiment can be taken out well. In other words, since the presser position of the flyer on the roving frame is 180° different in phase between the front row and the rear row, the edge of the grain of the capobin wound on the roving frame is 180 degrees different from that of the front row than that of the rear row.
80" are arranged on the opposite side. Therefore, the front and rear rows of full bobbins doffed by the roving machine are rearranged into a row with every other row in between, and the full bobbins in the row are placed in reserve using the bobbin carriage 17. When suspended from the rail 15, the edges 1ae of the edges 1a of these full bobbins are 1 as shown in FIG. 10(A).
They are placed every other 180 degrees on opposite sides. That is, the 10th
In figure (c), when the shin end 1ae of the full bobbin at the position of (al, (C1, e) is in the position facing the outlet nozzle 62, (bl, (d),
(The end 1ae of the full bobbin at position n is on the opposite side of the outlet nozzle 62. In this state, if all six full bobbins are returned and rotated at the same time in order to be fed by the outlet nozzle 62, Since the distance between the bobbins is generally small, by the time the shin edge located on the opposite side to the outlet nozzle 62 reaches the outlet nozzle 62, the shin edge is attached to the circumferential surface of the adjacent full bobbin, and the full bobbin is It may become wrapped around the body and become impossible to access.Therefore, at the beginning of the Shino exchange operation,

As shown in the figure, the six full bobbins MI5i1ae are aligned so as to face the outlet nozzle 62, and then the six full bobbins are rotated in the unwinding direction. Note that when the distance between full bobbins is large, it is sufficient to rotate them all at once in the unwinding direction from the beginning without rotating them in the winding direction in advance. In order to make the six pegs 53 rotatable every other time as described above, each peg 53 is rotatably supported by the changer 71 as shown in FIGS. Three pegs 53a
, 53c, and 53e are rotatable by a belt 163 via pulleys 162a, 162c, and 162e provided below the respective pegs, and the other three pegs 53b, 53d, and 53f are also rotated by the pulley 162b.

It is rotatable by a belt 164 via 162d and 162f. A motor 57 drives the belts 163 and 164 via drive pulleys 57a and 54a.

This is a guide pulley that guides the As shown in FIG. 10 (bl, +dl.

In order to rotate every other full bobbin 1a at the ff1 position 180° in the winding direction (clockwise), the motor 54 is first rotated.
In order to rotate counterclockwise in Figure 1 and rotate the entire full bobbin la in the unwinding direction (counterclockwise), motor 5 is required.
4 and 57 in the clockwise direction in FIG. 11 at the same time.

The full bobbin peg 53 is supported by a bearing attached to the changer 71, as shown in FIG. 13 (corresponding to pegs 53a, 53c, and 53e in FIG. 12)! To
166 is rotatably supported, and the upper end of this support shaft 166 is provided with a fitting part 166a that can be fitted and removed into the lower hole of the bobbin, and the middle part of the support shaft 166 is provided with a flange-shaped receiving part 16 on the outer periphery.
A cylindrical bobbin receiving body 167 having a diameter 7a is fitted so as to be movable up and down, and the bobbin receiving body 167 is attached to the support shaft 1.
The spring 169 interposed between the spring receiving plate 168 fitted to the base of the bobbin receiving body 16 is formed to have a larger diameter than the lower hole of the fitting part and can support the bobbin.
The outer periphery of the cylindrical portion 7 is formed to have the same or smaller outer diameter than the fitting portion 166a, so that it can be fitted into the lower hole of the bobbin.

Next, the small bobbin exchange head 55 will be explained. It is also necessary that the small bobbin exchange head 55 be configured to move up and down and back and forth with respect to the edge spinning machine. The mechanism for this purpose is almost the same as that for the full bobbin exchange head, and the mechanism for providing vertical movement is three small bobbin beds 56 on each side of the full bobbin exchange head lifting mechanism 31, as shown in FIG. Small bobbin exchange head lifting and lowering mechanisms 41a and 41b are provided for vertically moving the small bobbin exchange head. Lifting bodies 47a, 47b of respective lifting mechanisms 41a, 41b
have two chains 45 each extending in parallel in the vertical direction.
a, 46b, 46c, and 46d are connected, and the chains 46a, 46b, 46c, and 46d are moved both up and down using a small bobbin exchange head lifting mechanism motor 42 disposed within the main body 51 of the Shino exchanger 50. As a result, the elevating bodies 47a and 47b are moved up and down.

H, in 46a, 46b, 46c, 46d
To illustrate the movement of the chain 46a as an example, the rotation of the motor 42 is controlled by the chain wheel 43a fixed to the motor output shaft.
, the rotation of the link shaft 44 is transmitted to the link shaft 44 via the chain 43b and the chain wheel 114a fixed to the link shaft 44, and the rotation of the link shaft 44 is transmitted to the chain 46a by the chain wheel 45a. On the other hand, the back and forth movement of the small bobbin exchange head 55 can be performed using a mechanism similar to the back and forth movement mechanism of the full bobbin exchange head 52 shown in FIG. , and can be moved to a position directly below the spare bobbin hanger 24 and a position directly below the front row bobbin hanger 19, respectively.

The configuration of the pegs 56 in the small bobbin exchange throat 55 is the same as the configuration of the full bobbin peg 53 shown in FIG. 13, while the mechanism for rotating each peg 56 is shown in FIGS. 11 and 12. Peg 53 for Tamman bobbin
It is similar to the rotation mechanism of However, small bobbin exchange head 5
It is sufficient that the three pegs 56 of each of the three pegs 56 of the pegs 56 are always rotated simultaneously in the same direction, and therefore, one belt and a motor for driving the pegs 56 may be provided for each of the left and right small bobbin exchange heads 55.

Next, we will sequentially explain the outlet nozzle operating mechanism, the Shinogake head operating mechanism, and the Shinokake plate operating mechanism. A pair of left and right outlet nozzles, Shinogake heads, and Shinogake, in which operating cams are arranged side by side, are plate operating mechanisms 65.
First, this operating mechanism 65 will be explained with reference to FIG. As shown in FIG. 6, a connecting operation cam 66, a lead-out operation cam 67, and a connecting operation cam 68 are fixed to one rotatable cam shaft 93 side by side. A cam follower 94 and a cam lever 95 for directing the cam follower 94 are provided corresponding to the respective cams 66 , 67 , 68 , and one end of the cam lever 95 is pivotally connected to the main body 51 of the Shino exchanger 50 via a pin 96 . At the other end are operating rods 97, 9B,.

99 are rotatably connected to each other. Although only one cam follower 94 and one cam lever 95 are shown in FIG. 6, a cam follower and a cam lever are provided corresponding to the respective operating cams 66, 67, and 68, and a rod 97 for operating the shinoni head and an outlet nozzle are provided. Operation rod 9
8 and shinokake are arranged so that the plate operating rod 99 extends upward or downward. A pair of left and right cam shafts 93
The rotation of the motor 87 arranged in the main body 51 of the Shino exchange a50 is made into the rotation of the chain wheel 90 through the deceleration a88, the chain wheel 89, and the chain 91, and the rotation is caused by the rotation of the chain wheel 90 through the long intermediate shaft 90a and the mutually meshing. This is achieved by transmitting the signal to the left and right camshafts 93 via matching gears 92a, 92b, and 92c (the one on the right in FIG. 1 is not shown).

Next, the outlet nozzle 62 and outlet nozzle operating mechanism will be explained with reference to FIG. Although this outlet nozzle operating mechanism is provided symmetrically on the left and right, only the one on the right in FIG. 1 will be explained, and the explanation on the one on the left will be omitted. The outlet nozzle 62 is connected to the nozzle mounting block at the lower end of the racket 1.
38 to the outlet nozzle support pipe 139, and the suction airflow reaching both ends of the outlet nozzle support pipe 139 from the blower 23 via the hose 23a removes the thin end of the full bobbin la from the tip of the outlet nozzle 62. It plays the role of drawing out. In order to guide the protruded Shinobata to the Wl head 60, the tip of the protruding nozzle 62 is traced 140 as shown in FIG.
It is designed to move along the curve shown in .

In the Shino exchanger 50 shown in FIG. 1, six outlet nozzles 62 are fixed to the support pipe 139 at intervals of two spindle pinches. The movement of the outlet nozzle operating rod 98 by the outlet operation cam 67 of the operating mechanism 65 explained in FIG. A swinging motion about a pin 126 is applied to the lifting arm +27 via a gear 124 and a sector gear 125.

The main body 51 of the Shino exchanger 50 has two straight rods 13.
A long hole 129 is provided in one portion 128a of the slider 128, and a sliding pin 131 provided at the tip of the lifting arm 127 is inserted into the long hole 129. The slider 128 is slidably fitted so that when the lifting arm 127 is swung in the direction of the arrow, the slider 128 can be moved up and down along the parallel guide 132. Slider lower portion 128
The right end of b rotatably supports one end of the outlet nozzle support pipe 139. A guide plate 134 having a curved guide hole 135 that defines the trajectory of the tip of the outlet nozzle 62 is disposed in the main body 51 of the Shinoko JA machine 50, and a sliding pin 136 that engages with the curved guide hole 135 is attached to the connecting arm. The connecting arm 137 is provided at one end of the connecting arm 137, and the other end of the connecting arm 137 is integrally connected to the outlet nozzle supporting vibe 139. Therefore, when the slider 128 rises, the outlet nozzle 6
2 itself rises, and each time the sliding pin 136 is guided along the curved guide hole 135, the outlet nozzle 62 is rotated around the pipe 139, and the tip of the outlet nozzle 62 is moved along the trajectory indicated by 140. It will be moved. It is preferable to provide a comb inside the tip of the outlet nozzle 62 to help cut the wire.

Next, the Shinotsugi head 60 and the Shinotsugi head operating mechanism will be explained with reference to FIG. This Shinotsugu head operating mechanism is also provided symmetrically in a pair on the left and right. The thread joint head 60 is a device that superimposes the a= drawn out from the full bobbin by the outlet nozzle 62 into the thread of the small bobbin being spun, and cuts the thread of the small bobbin after the polymerization. In addition, in the Shino exchanger 50 shown in FIG.
(see figure). When the outlet nozzle 62 is suctioning the edge, the 1N joint head 60 is directed vertically downward from the edge joint head support bar 148 to avoid interference with the outlet nozzles 6 and 2, as shown in FIG. Next, the shinodashi is held and rotated counterclockwise in order to polymerize the shinodashi with the shinobin of the small bobbin being spun.
It must be moved to the right in the diagram. A 7-do work for Shinotsugu that gives a similar motion to the Shinotsugu head 60! 7I

It is pulled counterclockwise by 52 and 153,
The inner link 146 is received by the stopper 51h. The pivot shaft 145 can be rotated by a pair of left and right supports 51e and 5Le fixed to the main body 51, and the outer link 1
The lower end of 47 is fixed.

A sector gear 144 is fixed to the end of the pivot shaft 145, and this sector gear 144 is connected to the swing arm 1.
It meshes with a gear 1418 that is integrated with 41. A pin 151 is provided at the upper end of the outer link 147 and engages with a long hole 150a of the connecting link 150.

The upper end of the self-recording inner link 146 is connected to the Shinotsugu head support bar 14
The upper end of the connecting link 150 is fixed to the pin 149, and the upper end of the connecting link 150 is fixed to the pin 149.
is rotatable about the pin 149 by the rocking of the connecting link 150.

Therefore, when the swing arm 141 rotates counterclockwise about the pin 143 due to the downward movement of the rod 97 for operating the Shinotsugu head, the outer link 147 is connected to the spring 15 via the sector gear 144 and the pivot 1=t4s.
The outer link 14 swings clockwise against the tensile force of 3.
Push the pin 151 at the upper end of 7 to the right and turn the connecting link 150 counterclockwise around the pin 149. As a result, the Shinotsugi head support bar 148 rotates counterclockwise together with the Shinotsugi head 60.

This pivoting movement continues with the connecting link 150 from the position shown in FIG. 8 to a position symmetrically opposite to the vertical passing through the pin 149, so that the sash joint henode 60 is in a substantially horizontal position. When the rod 97 for operating the Shinotsugu head further moves downward and the outer link 147 further rotates clockwise, the pin 151 comes into contact with the lower end of the elongated hole 150a, and then the pin 149 is pulled to the right by the connecting link 150. The inner link 146 is rotated around %=145, and the horizontally oriented Shinotsugu head 60 is rotated at 15%.
4, it will proceed towards Shino R from the small bobbin IC which is currently being spun.

The arrangement position of the spinning frame and the position of the drafting section 5 in the spinning frame are usually shifted by 172 pinches of the spindle of the spinning frame, as shown in FIG. Then, take out the full bobbin Shino, hold the Shino in the 'PJ'm hand drawer 0, and place it on the drafting part 5 side at 172.
Only the spindle pitch needs to be moved laterally. For this purpose, as shown in FIG. 1, a lateral movement mechanism 61 for the joint head is provided to move the pivot shaft 145. The Shinotsugu head lateral movement mechanism 61 includes a motor 217 with a reducer fixed to the main body 51, a worm 218 rotated by the motor 217, a worm J meshing with the worm 218; It consists of an arm 155 that swings about 155a, and the arm 15
By swinging 5, the rod 145 is selectively moved to the right or left in FIG.

Next, with reference to FIGS. 14 to 17, the structure of the shinotsugi head 60 and its operating method will be described. FIG. 14 shows a plan view of an embodiment of the Shinotsugu head, and FIG. 15 shows a side view thereof. The Shinogi head 60 shown in FIGS. 14 and 15 has a Shinogi head main body 171 having a Shino guide groove 173 formed at its tip, and a Shinogi head body 171 that has a Shinogi guide groove 173 in a plane parallel to the upper surface of the main body 171. The gripping lever 174 is configured to have a gripping lever 174 that can reciprocate horizontally. The main body 171 is fixed to a cylindrical head support bar 148 having a U-shaped cross section. The Shino grip lever 174 is rotatably supported near the center by a pivot pin 178 fixed to the main body 171, and has a pin 179 protruding from its rear end. As shown in FIG.
1 bar 182 is disposed, and the actuating bar 182 has an actuating member 181 having an opening for accommodating the pin 179 at its tip.
is fixed. Nip pieces 176 and 177, which have respective gripping surfaces 176a and 177a opposite to gripping surfaces 175a and 175b on both sides of the gripping portion 175 at the tip of the gripping lever 174, are attached to the main body 171 at positions on both sides of the gripping groove 173. It is fixedly disposed on the upper surface. A triangular-shaped shell guide opening 172 for guiding the shell to the shell guide groove 173 is formed at the tip of the main body 171, and one side of the shell guide opening 172 is provided with a triangle-shaped shell guide opening 172 for guiding the shell to the shell guide groove 173. An opening for a nozzle 183 is provided to eject water toward the bottom of the groove 173.

The air flow ejected from this nozzle 183 serves to lengthen the bending of the grain end of the full bobbin which is polymerized into the grain of the small bobbin during spinning. FIG. 14(A) shows a case where the actuation bar 182 moves to the right and grips a small bobbin (not shown) between the gripping surface 175a of the gripping lever 174 and the gripping surface 177a of the nip piece 177. and a Shino gripping lever 17 in a standby state for guiding a full bobbin into the Shino work inner groove 173.
4 position is shown. When the Shino joint head 60 is positioned in the vertical position described with reference to FIG. 14(C), the Shino gripping part 175 rotates to the right and is gripped by the Shino gripping lever 174 and the nip piece 176, and then the Shino joint head 60 is While being moved from the vertical position to the horizontal position, the wire between the outlet nozzle 62 is cut into a brush tip shape on the downstream side of the gripping point by the wire gripping lever 174, and as a result, the 8 guide grooves 1
In 73, a brush tip-like grain end which is to be polymerized with the grain of the small bobbin during spinning is placed. In this state, the Shino joint head 60 is brought close to the Shino R of the small bobbin being spun along the trajectory shown by the solid line 154 in FIG. 8, and moved to the right or left 172 in FIG. The spindle pitch is moved laterally, whereby the grain R of the small bobbin being spun, which has been introduced into the trumpet 5, is introduced into the grain guide groove 173, and the grain end of the full bobbin is superimposed on the grain R of the small bobbin. be done. Next, Figure 14 (B
), the Shino gripping part 175 of the Shino gripping lever 174 is rotated to the left and moved to the neutral position, whereby the Shino end of the full bobbin is guided to the Shino R of the small bobbin and placed in the I-run bet 6. is introduced in a polymerized state. Thereafter, when the thin end of the full bobbin is introduced into the hack roller 5a of the drafting section 5, the thin gripping section 175 is rotated to the left as much as possible as shown in FIG. 14(A), and the thinning gripping lever is 174 Shino grip part 17
5's left gripping surface 175a and left nip piece 177
The small bobbin Shino R is gripped between the gripping surface 177a and the gripping surface 177a. In this way, the shino on the downstream side of the shino joint head 60 is spun toward the drafting section 5, so the spliced part advances downstream, and the shino R upstream of the shino jointed part is connected to the shino grip lever 174 and the nip piece on the left side. Since it is gripped at 177, it is pulled and cut to complete the shinonitsu. Thereafter, the Shino gripping lever 174 rotates to the neutral position, and the grip on Shino R is released.

Next, referring to FIG. 17, the sliding movement of the actuating bar 182 that operates the rotational movement of the Shino gripping lever 174 will be explained. 1st
As shown in FIG. 7, an operating member 181 of each of the six Shinogi heads 60 is fixed to an actuating bar 182 housed in the Shinogi head support bar 148. Actuation bar 1
The plungers 189 of four working chamber bar sliding solenoids 185 fixed to the '6M 4I head support bar 148 are connected to the L-shaped member 188, the pin 200, and the hole 186, respectively. When each solenoid 185 is not energized, the plunger 189 can freely move, and when energized, the plunger 189 is closed.

The pin 200 engages the working chamber bar 182 through the hole 186 and transmits the movement of the plunger to the working bar 182. At this time, the shape of the hole 186 with which the pin 200 engages is the hole 186a corresponding to the solenoids 185a and 185d.
, 186d are elongated holes extending in the direction of movement of the operating bar 182, and holes 186b, 186c corresponding to the solenoids 185b, 185c are formed as elongated holes extending in a direction perpendicular to the direction of movement of the operating bar 182. Figure 17 (
As shown in A), energize (ON) the solenoid 185c.
Then, the plunger 189 is inserted into the solenoid 185c, moves the pin 20C to the right as shown by arrow C, moves the actuating bar 182 to the right as shown by arrow The tip 175 rotates to the left and comes into contact with the nip piece 176 to grip a full bobbin (see Figure 14 (C)). Next, the Shino gripping lever 174 is shown in Figure 14 (B). In order to bring the operating bar 182 to the neutral position, turn on the solenoid 185d and move the pin 200d in the direction of the arrow as shown in FIG. 17(B). move in the direction. At the same time, Soleno Ido 185
a is also energized, and the plunger 189 of the solenoid 185a
Since the t-bar 182 remains in the retracted position, the right end of the long hole 186a abuts the pin 200a, and the actuating T-bar 182 is positioned at the neutral position.

Furthermore, in order to move the grain gripping lever 174 to the position shown in FIG. 14(A) where it grips the grain of the small bobbin being spun, the solenoid 185b is used as shown in FIG. 17(C).
By retracting the plunger 189, the pin 200b is moved in the direction of arrow B, and the actuation bar 182 is moved in the direction of arrow X3.

By repeating the above steps, the reciprocating rotational movement of the Shino gripping lever 174 in the Shino joint head 60 can be achieved based on a predetermined plan.

FIG. 16 shows another embodiment of Shinotsugu Hendro 0.

In this H'm head 60, as can be easily seen from the side view shown in FIG. 16 ([3)], a lever 174a for holding a full bobbin and a lever 174b for B and R during spinning from a small bobbin are used as the gripping levers. The fact that two of these are used is the 15th
This is different from the Shinotsugu head 60 shown in the figure. Therefore, correspondingly, the operating bar 182a for full bobbin line and the operating bar 182b for Wl are used to cut line R upstream from the planned polymerization area and to It operates in the same manner as in the case of the shown joint head 60, and the joint end of the full bobbin is overlapped with the joint R of the small bobbin to complete the joint.

Next, with reference to FIG. 9, Shinokake will explain the plate actuation mechanism'. The plate operating mechanism of this Shinokake is also provided symmetrically on the left and right. The Shinokake plate 58 is a plate for hanging the fully loaded bobbin Shino on the roping guide 2. To do so, the Shinokake plate 58 must be moved along the trajectory shown by the curve 116 in FIG. I have to let it happen.

In the Shino exchanger 50 shown in FIG. 1, the cross plate 58 is formed as a single plate extending in the longitudinal direction of the Shino exchanger 50. The plate operating mechanism is a link mechanism that combines the outer link 101 and the inner link 102 to move the plate operating rod 95 downward by the operating cam 68 of the operating mechanism 65 shown in FIG. By this movement, the Shinokake gives the plate 58 a desired movement trajectory. That is, sector gear 104
is attached to the main body 51 via a pin 109, and the shaft rotates clockwise around the pin 109 by the downward movement of the plate operating rod 95, and the movement is caused by the counterclockwise rotation of the sector gear 105. brings about a rotation in direction. This sector gear 105 is fixed to a shaft 112 which is supported rotatably and slidably in the longitudinal direction by a support 103 attached to the main body 51, and the upper end of the outer link 101 is fixed to this shaft 112. has been done. The lower end of the outer link 101 has a pin 11 implanted in the connecting link 107.
4a and a pin 115a implanted at the rear end of the support bar 108 so as to be rotatable.

A shaft 1 is attached to the support 103 so as to be rotatable and movable in the axial direction.
17, one end of the connecting link 106 is rotatable about the shaft 117, and the other end is rotatable about the shaft 112, and the movement of the link 112 in the axial direction is transmitted to the shaft 117. Then, the upper end of the inner link 102 is fixed to this shaft 117, and the lower end of the inner link 102: A is the connecting link 10 described above.
7 and a pin 113. A small float 114 is modeled on a pin 114a implanted in the connecting link 107, and a small float 115 is wedged onto a pin 115a implanted in the support lever 108, so that the small gears 114 and 115 mesh with each other.

A plate 58 is suspended and fixed to the tips of the support levers 108 on both sides (see Figure 1).Although not shown, the roving guide 2 is provided with a full bobbin that has been spliced. At this time, in order to regulate the lateral position of the shinokake, six square-shaped notches for the guide F are formed on the tip side of the plate of the shinokake (on the right side in FIG. 9). Due to this +14 formation, the outer link 101 and the inner link 102 both rotate counterclockwise as the sector gear 105 rotates counterclockwise, and as they approach the swinging end of the outer link 101, the outer link 101 and the inner link rotate. Link 102, connected link 1
Due to the connection length of 07, the connection link 107 is connected to the pin 114.
It is rotated counterclockwise with a as a fulcrum, and as the small gear 115 meshing with the small 1st gear 114 is rotated clockwise, the tip of the plate 58 will follow the trajectory shown in Figure 9. 11
6, and when it comes to the swinging end of the outer link 101, the plate 58 of the Shinogake above the roving guide 2 tilts toward the machine base, so that the Shinogake plate 58 with a full bobbin is guided into the roving guide 2. It has become.

Next, a mechanism for laterally moving the shinokake plate 58 will be explained. For example, the plate 58 is moved 201 in order to hang the pin of the full bobbin 1a on the claw portion 2b of the roving guide 2 shown in FIG. 1) is moved by the plate lateral movement mechanism 59.

The lateral movement of the plate 59 is rotated by a motor 117 with a speed reducer fixed to the main body 51 and a gear 117a by the motor 117. Warm 11
8 and the worm wheel that meshes with the worm 118 -
◇:! 1, and the arm 119 selectively moves to the right or left in FIG. 1 about a pin 119a to laterally move the shaft 112 of the plate actuating mechanism. As shown in FIG. 9, by the lateral movement of the shaft 112, the inner link 1
02 is moved horizontally at the same time, and the full bobbin Shino
The plate 58 of the Shinokake holding the plate 58 is also moved laterally.

This Shinokake is plate 58. The horizontal movement of Shinokake is plate 58.
This is carried out with the roving guide 2 being raised to guide the liner into the roving guide 2, and as a result, the liner is applied to the claw portion 2b of the roving guide 2.

As mentioned above, the Shino exchanger is provided with various operating mechanisms each having a motor. As will be clear from the explanation of the operation of the Shino changer to be described later, the movement of the outlet nozzle, the Shino connection head, the Shino hook plate, and the full (small bobbin) bobbin change head is performed in a predetermined order. For this purpose, the motors in the various actuators +11 are connected to the main body 51 of the Shino exchanger 50.
It is operated according to a predetermined order based on commands from the controller 300 disposed in the controller 300, thereby exchanging the full bobbin and the small bobbin, and also transferring the full bobbin to the small bobbin that is currently being spun. Shinotsugi is performed. Since the configuration and operation of the controller are well known, detailed explanation will be omitted.

Next, a case will be described in which the Shino exchange 550 having the above configuration is used to perform Shino exchange in a broad sense, that is, exchange of a full bobbin and a small bobbin, and a Shino joining operation. First, as shown in Figure 3, when spinning progresses, the bobbin hanger 1 in the front row of the creel of the spinning machine
The bobbin suspended from 9 is the small bobbin IC, and the bobbin suspended from the bobbin hanger 20 in the back row is the medium bobbin 1.
At the time b, the guide roller 29 of the Shino exchanger 50 is placed on the guide rail 28 of the spinning machine, and the Shino exchanger 50 is connected to the spinning machine. For this special train, we have prepared a spare rail 1 for the spinning machine in advance.
5, a full bobbin 1a is placed on a spare bobbin hanger 24 arranged facing the position of the bobbin hanger 19 in the front row of the spinning machine.
Let it hang. In addition, if the bobbin suspended from the bobbin hanger 20 in the rear row becomes a small bobbin and it becomes necessary to replace the bobbin, the above-mentioned bobbin shunter 10 is used to arrange the small bobbin in the front row in advance. I'll keep it.

The Shino changer 50 travels along the front surface of the spinning machine by driving the scroll cam 22 with the travel motor 21, and stops at a position corresponding to the 6-piece of the small bobbin 1c. At this position, a series of operations for replacing the wire and joining the wire are performed in sequence. The operation will be explained below with reference to FIG. 19.

First of all, the small bobbin 1c in the front row has less remaining shine and is in a state where it needs to be replaced (Fig. 19 (1)).
. When this state is reached, as shown in FIG. 19 (2), the full bobbin exchange head 52 corresponding to the position immediately below the full bobbin 1a suspended from the bobbin hanger 24 of the spare rail 15 is raised by the lifting mechanism 31, and Bobbin exchange head 52
The peg 53 fits into the lower part of the full bobbin 1a, and the full bobbin 1
Remove a from the bobbin hanger 24. Full bobbin exchange head 52 descends and returns to the original position shown in FIG. The outlet nozzle 62 stops at a position where the suction port of the outlet nozzle 62 corresponds to the height of the edge of the fully loaded bobbin 1a that has been raised by the operating mechanism and lowered (FIG. 19 (3)). The motor 54 of the peg rotation mechanism built into the exchange head 52 rotates counterclockwise when viewed from above, and preliminarily rotates every other full bobbin, the end of which is on the opposite side of the outlet nozzle 62, by 180 degrees in the winding direction. The bobbins are rotated and the thin ends of the full bobbins are moved to the outlet nozzle 62 side.

Thereafter, the motors 54 and 57 are rotated clockwise to rotate the six full bobbins in the unwinding direction, and the suction force by the 7'' lower 23 is applied to the outlet nozzle 62. As a result, the suction ports of the outlet nozzles 62 reliably suck the edges of the corresponding full bobbins and extract the edges of the full bobbins 1a (FIG. 19 (4)). While continuing the rotation of the full bobbin 1a and suction by the outlet nozzle 62, the outlet nozzle 62 descends and returns to its original position, and the recessed sag enters the sag guide groove 173 of the sag joint head 60 (No. 19). Figure (5)). The solenoid 185c of the Shino joint head 60 is energized, the Shino gripping lever 174 is activated, and the B gripping portion 175 and the nip piece 1 are moved.
76, the full bobbin 1a is gripped, and at the same time, the thread head, which was in a downward vertical position, is brought to a sideways, almost horizontal state by the thread joint head operating mechanism, and at this time, the thread of the full bobbin 1a is held at the tip of the outlet nozzle 62. It is caught by the comb installed inside and is cut between the gripping point on the shin joint head 60 and the outlet nozzle 62 to form a shin end (FIG. 19 (6))
. Next, the thread joint head 60 moves forward toward the drafting section 5 of the spinning frame by the thread joint head operating mechanism while holding the full bobbin grain on which the grain edge has been formed. 'The B-joint head 60 temporarily stops moving forward while moving forward, and the thread of the small bobbin moves laterally by the amount of the introduced dollar pitch to the position in the longitudinal direction of the spinning machine corresponding to the trumpet 6 upstream of the drafting section 5 of the spinning machine. After that, the forward movement was resumed, and Shinohata of Shino with a full bobbin was on trumpet 6.
Continue until you reach the top of the .

At this time, the grain of the small bobbin being spun enters the grain guide groove 173 of the grain joining head 60, and overlaps with the grain of the full bobbin.

Note that when the Shino joint head 60 advances, the full bobbin is rotated counterclockwise by the peg rotation mechanism of the full bobbin exchange head 52 to unwind the Shino and prevent the Shino from being cut due to the advance of the Shino joint head 60. At the same time, in order to hold the slack in the unwound shin, the shinokake plate 58 is slightly raised by the shinokake plate operating mechanism. Shinotsugu head 60
stops moving forward, the solenoid 18 of the Shinotsugu head 60
5a.

185b is energized, the Shino gripping lever turns to the neutral position, releases the Shino grip on the full bobbin, and the full bobbin 1a is released.
The grain is attracted by the grain of the small bobbin being spun and inserted into the trumpet 6 together with the grain. After the grain end of the full bobbin 1a is gripped by the hack roller 5a of the drafting section 5, the grain is transferred to the grain joint head 60. Solenoid)" 185b is energized, and the Shino grip lever 1
74 rotates further and the Shino grip part 175 and the nip piece 17
7. Grip the small bobbin's Shino. Since the small bobbin is held by the Mff Na head 60, it is drafted and cut between it and the buff crawler (see Fig. 19).
7)). The full bobbin 1a that has completed the splicing is raised again by the full bobbin exchange head 52 until it reaches the limit where it will not be attached to the spare bobbin hanger 24, and then stopped. At this time, the full bobbin 1a is rotated counterclockwise by the peg rotation mechanism of the full bobbin exchange head 52 to unwind the peg, thereby preventing the peg from being cut due to the upper limit of the full bobbin 1a, and at the same time, the peg rotation mechanism of the peg rotation mechanism of the full bobbin exchange head 52 prevents the peg from being cut due to the upper limit of the full bobbin 1a. further rises close to the roving guide 2 and holds the slack of the fully unwound bobbin 1a. During this time, solenoid 185a of Shinotsugu Hendro 0,
185d to move the Shino gripping lever 174 to the neutral position, thereby releasing the grip of the small bobbin by the Shino gripping lever 174, and moving the Shino joint to the position where the Shino of the full bobbin 1a is removed from the Shino joint head 60. The head 60 moves backward and stops (FIG. 19(8)). To replace the small bobbin, the hood 55 advances to just below the small bobbin in the front row of the creel using the forward/backward movement mechanism and the lifting mechanism, moves upward, and removes the small bobbin 1c from the bobbin hanger 19 in the front row (Fig. 19 (9)).
). The small bobbin exchange head 55 carrying the small bobbin moves downward (FIG. 19 00)) and retreats to return to its original position. (
Figure 1900). A peg rotation mechanism built into the small bobbin exchange head 55 rotates the small bobbin clockwise when viewed from above, and winds up the cut wire. When the small bobbin exchange head 55 returns to its original position, the full bobbin exchange head 5
2 goes down and returns to normal. At that time, replace the full bobbin, de 52
The full bobbin 1a is rotated by an appropriate amount in the clockwise direction by the begging rotation mechanism to wind up the wire, and the slack in the wire caused by the lowering of the full bobbin exchange head 52 is properly maintained. After the Shinokake plate 58 is at its maximum limit, the Shinokake plate 58 is laterally moved by the English inspection mechanism 59 to pass the Shino of the full bobbin 1a through the roving guide 2 installed in the spinning machine and hang it. At the same time, the Shinotsugu head 60 retreats and returns to its original position. During the retreat, the shin joint head 60 stops retreating, moves laterally, and returns to a position corresponding to the creel bobbin when viewed in the longitudinal direction of the spinning machine (FIG. 19, 0δ). After the retreat, the Shinotsugu head 60 is returned from a substantially horizontal state to a vertical state (FIG. 19, 0-2). The full bobbin exchange head 52 moves forward to just below the bobbin hanger 19 in the front row, moves upward, and attaches the full bobbin 1a to the bobbin hanger 19. At this time, the full bobbin la is rotated by an appropriate amount in the clockwise direction by the rotating mechanism of the full bobbin exchange head 52 to properly maintain the slack of the thread caused by the forward movement and elevation of the full bobbin exchange head 52. Then small bobbin exchange head 55
advances to just below the spare bobbin hanger 24 of the spare rail 15, rises, and attaches the small bobbin to the bobbin hanger 24. In Shinokake, the plate 58 descends, moves laterally on the way, and returns to its original position (FIG. 19, 041). The small bobbin exchange head 55 descends, retreats, and returns to its original position, and the full bobbin exchange head 52 descends, retreats, and returns to its original position (FIG. 19, 05)).

Thus, the Shino exchange work of the cycle is completed, and the Shino exchange machine 5
0 moves laterally by six bobbin hangers 19 in the front row and then stops, and the thread exchange operation is repeated sequentially from one end of the spinning frame to the other end.

The Shino exchanger 50 may perform the Shino exchange and Shino joint work in accordance with the following procedure. Raise the full bobbin exchange head 52 and remove the full bobbin 1.
After fitting a into the peg 53 (Fig. 19 (2)), the small bobbin exchange head 55 is advanced and raised to remove the small bobbin 1.
Remove c from the front row bobbin hanger and return to the original position. The full bobbin 1a and the small bobbin IC are spun in the positional relationship shown in FIG. Next, move on to replacing the full bobbin - Lower the throat 52 and take out the thin end from the full bobbin 1a in the same way as above, then transfer the bright end to the 7+58v head 60.
Grip it and guide it above the trumpet to perform Shinotsugi. After the Shino-tsugi is finished, move the full bobbin 1a to the front row bobbin hanger I.
9, and the small bobbin lc is suspended from the spare bobbin hanger 24 of the rail after winding up the thread hanging from the roving guide 2.

In this way, when the small bobbin IC being spun is placed on the bed 56 of the small bobbin exchange head 55 and the shin splicing is performed, the shino being spun from the small bobbin lc to the roving guide 2 is connected to the small bobbin. Rotate the small bobbin IC counterclockwise so as not to interfere with the full-bobbin 1a in front of the bobbin IC to give an appropriate amount of slack, and rotate the small bobbin IC at a speed equivalent to the spinning amount of the shin until the shin splicing work is completed. It is necessary to continue unwinding and rotating the IC. However, according to this method, the second
In the embodiment shown in FIG. 2, when replacing the full bobbin 1a and the small bobbin IC after the completion of the connection, the full bobbin 1a is retracted upward to avoid interference between both bobbins (FIG. 19 (9) to 0).
The operation of the full bobbin 1a of υ can be omitted.

In this embodiment, since the Shinotsugi head 60 is provided so as to correspond to the center of the full bobbin 1a, the Shinotsugi head 60 is moved laterally by 172 spindle pinches while it is moving forward, so that it corresponds to the trumpet 6. There is this 1/
The lateral movement for two spindle pinches is performed using the same spinning machine, and the spinning machine is first moved to the left side, and then moved to the right side during the next change of wire. In other words, the small bobbin Ic is alternately moved horizontally to the left and horizontally to the right.
It goes without saying that - should guide the Shinotsugu head 60 above the trumpet 6 on the spinning side.

If the Shinotsugi head 60 and the outlet nozzle 62 are designed to be able to move laterally by the amount of spindle pinch, and the Shino end of the full bobbin la is brought out at the position corresponding to the trumpet 6, the lateral movement of the Shinotsugi head 60 during forward movement can be avoided. You don't have to do three glue operations. In this case, before taking out the shin end from the full bobbin 1a, the shin joint head 60 and the shin end nozzle 6 are connected.
2 is moved in advance to a position corresponding to the trumpet 7 to 6 spun by the small bobbin IC.

When the sunrise nozzle 62 is set at a position corresponding to the trumpet 6, and the Shinotsugu head 60 is positioned so that it can move by the spindle pitch, the lateral movement of the Shinotsugu head 60 during its forward movement is changed to the lateral movement by the spindle pinch. It will be done alternately. When the suction airflow of the winding nozzle 62 is made to generate a swirling airflow in the direction opposite to the twisting of the windshield, the windshield ends drawn into the winding nozzle 62 from the full bobbin 1a are twisted back and separated. The Shinohata may be brought out from the Naoman bobbin 1a by attaching the Shinohata to a brush, a moquette, or the like. If the suction port of the pick-up brush and pick-up nozzle 62 is designed to be able to be raised and lowered from the standby position of the Shino exchange ja, 50 to a position opposite to the outer periphery of the full bobbin 1a suspended on the spare rail, Hanging Tama＼
Now, it would be fine to put out the thread end of the full bobbin 1a and perform the thread joint, and after the thread joint is finished, remove the small bobbin IC and replace the thread, but it is necessary to increase the lifting amount of the threading brush and the threading nozzle. Therefore, the Shino switching device 50 becomes large. Further, in the above embodiment, after splicing, the cutting of the grain of the small bobbin during spinning is gripped by the grain gripping lever 174 and the nip piece 177, and the grain is pulled off by spinning by the hack roller 5a and IVr. However, the present invention may be arranged so that the lower surface of the shinobi gripping lever 174 and the upper surface of the nip piece 177 of the above embodiment rub against each other, so that the shinobi can be cut like scissors by the lower surface of the shinobi gripping lever 174 and the upper surface of the nip piece. It does not deviate from this. Further, the reciprocating movement of the Shino grip lever 174 across the Shino guide groove 173 may be performed by fixing the Shino grip lever 174 to the operating bar 182 and moving it in parallel. Furthermore, when the Shino grip levers 174 of a plurality of Shino joint heads 60 are operated by the same actuation bar 182,
It is preferable to interpose a spring between the blade gripping lever 174 and the actuating bar 182 so that each blade connection head 60 can reliably grip the blade.

〔Effect of the invention〕

As described above, in the present invention, when the Shinomaki bobbin that is being spun by hanging from the bobbin hanger becomes a small bobbin, first, the Shino of the full bobbin to be replaced with the small bobbin is taken out, and the Shino end is After gripping and guiding it upward to polymerize the grain of the small bobbin being spun, release the grip on the end of the grain of the full bobbin and cut the grain of the small bobbin to perform grain joining. As a result, the threading can be performed reliably and in a short time with simple movements while the spinning machine is running.
It is possible to automate the seaming work. By automatically hooking the thread of a full bobbin that has been spliced onto the roving guide, it is possible to completely automate the thread splicing and thread replacement. In addition, when the thin end of a full bobbin is tapped by the suction airflow of the tip nozzle, it is possible to reliably pull out a weak dark edge, which is practical.
