Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a thread exchanger in a spinning machine, and more specifically, a thread exchanger that mechanically performs a thread exchange when replacing a small ball pin and a full bobbin. It is related to.

Conventional technology Previously, in order to mechanize the replacement work, the
As shown in No.-81631 and JP-A-58-120826, a Shino exchange machine has been developed in which a small bobbin of a creel is exchanged with a full bobbin prepared in advance.

Problems to be Solved by the Invention The conventional Shino exchange machine described above only exchanges small bobbins and full bobbins sequentially from one end of the spinning machine to the other end. The replacement of Shino was still done manually, and there was a problem in that it required a lot of labor. Therefore, a Shino-tsugi machine is being developed that performs Shino-tsugi as well as Shino-tsugi exchange, but if a mistake is made when starting Shino-tsugi, thread breakage will occur, and the Shino of the thread-cutting weight will be There is a risk that the wire will get wrapped around the draft roller, causing a breakdown of the machine and wasting the wire, which is a factor that hinders the automation of wire joining work.

Conventionally, in order to prevent the thread of the thread cut generation weight from wrapping around the draft roller, as shown in Japanese Patent Application Laid-Open No. 47-4727, a thread that detects thread cuts is installed in an automatic yarn splicing machine that moves around. It has been proposed that a thread breakage detector and a roving cutter capable of cutting the thread being supplied are installed, and when a thread breakage is detected, the thread of the weight is cut. When replacing yarn, it is necessary to stop the automatic yarn splicing machine to avoid collisions between working machines, so if the yarn breaks due to a mistake in splicing when changing yarn, the automatic stop of yarn feeding will be delayed, and the rollers of the yarn will be damaged. There was a problem that could easily lead to accidents due to wrapping.

Means for Solving the Problems The present invention solves both of the above problems and provides a practical Shino changer, in which a full bobbin is placed in advance at a standby position provided along the creel, and the creel is replaced with a full bobbin. When the Shino-maki bobbin becomes a small bobbin, it moves along the front of the spinning frame table and the small bobbin and the full bobbin are exchanged one after another. A thread nozzle that has been opened, a thread connecting head that grasps the exposed end of the thread and supplies it to the drafting section, and a thread connecting head that cuts the thread of the small bobbin that is being supplied to the drafting section, and a thread with a weight that corresponds to the thread connecting head. a thread trimming detection device capable of detecting thread cutting;
The present invention is characterized in that it is equipped with a shingle supply stop device capable of stopping the supply of shingle to the drafting section of the shingle joint weight when the thread breakage detection device detects thread breakage.

Function: When the creel's Shino bobbin becomes a small ball, the Shino exchange machine moves along the front of the spinning frame and stops at the position corresponding to the first Shino exchange weight, and at that position, the creel's small bobbin and the pre-standby position are moved. Replace the full bobbin placed in the At the time of this thread exchange, the thread end of the full bobbin to be replaced is drawn out by suction with a lead-out nozzle, and the drawn-out thread end is gripped by a thread joint head and fed to the drafting section and drawn. The thread of the small bobbin supplied to the extension section is cut and the thread is joined. If a mistake occurs during the thread splicing and a thread break occurs with the thread thread cutter, the thread cut detection device immediately detects the thread cut and activates the thread feed stop device almost at the same time as the thread cut occurs. , the supply of Shino of the full bobbin at the spindle where the Shino connection error occurred is stopped.

Embodiment In this embodiment, a series of shim changing operations are performed by the sash changing machine 50 shown in FIG. 1 (front view) and FIG. 2 (side view). As shown in FIG. 3, the Shino changer 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 for spinning creels are established at appropriate intervals in the longitudinal direction of the frame in the center of the frame 3 of the spinning frame, and above the drafting section 5 of the spinning frame, Bobbin hangers 19 and 20 are supported by two front and rear rails 11 and 12, respectively, which are supported by the creel pillar 4 using a support bracket 18, a support bracket 13, and a hanging rod 14. A small bobbin 1c and a medium bobbin 1b are suspended from these bobbin hangers 19 and 20. Bobbin hanger 1 of these front and rear rails 11, 12
9 and 20 are arranged so as to face each other in the front and back every two pitches, that is, every two spindle pitches, of the drafting section 5, that is, the trumpet 6, as shown in FIG. 4 as the positions of the small bobbin 1c and the medium bobbin 1b. There is. The bobbin hanger 19 on the front rail 11 will be referred to as a front row bobbin hanger 19, and the bobbin hanger 20 on the rear rail 12 will be 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 row bobbin hangers 19, 20. As shown in FIG. This roving guide 2 is the fourth
As shown in the figure, a raised part 2a that is formed in a ring shape having an opening 2c and protrudes toward the side opposite to the opening 2c, and claw parts 2b that protrude upward on both sides adjacent to the opening 2c. It is provided. The raised portion 2a is formed between the front row bobbin 1c and the rear row bobbin 1.
The pawl portion 2b is useful for separating the grain supplied from the roving guide 2, and the claw portion 2b is useful for hanging the grain of a full bobbin after it has been spliced to the roving guide 2.

A spare rail 15 attached to the tip of the support bracket 13 is disposed above the front row bobbin hanger 19 along the longitudinal direction of the machine. The preliminary rail 15 is formed into a hollow columnar body with a square cross-sectional shape and an open bottom, and a bobbin carriage 17 is inserted into and out of the open end of the column, and is movable along the preliminary rail 15. The bobbin carriage 17 has a spare bobbin hanger 24, and as shown in FIG. 3, a full bobbin 1a is suspended from this bobbin hanger 24, and a small bobbin 1c can also be suspended after the bobbin replacement work. .

As shown in FIG. 3, the bobbin changing operation involving the bobbin splicing is performed between the small bobbin 1c of the front bobbin hanger 19 and the full bobbin 1a of the spare bobbin hanger 15. After the thread replacement work is completed, the thread R of the full bobbin 1a of the front row bobbin hanger 19 is guided to the back thread guide 308 that is supplied to the back roller 5a of the drafting section 5 via the roving guide 2 and the trumpet 6, and then is guided by the spindle 25. It is twisted 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 this time, in this embodiment, 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 foregoing exchange is accomplished by removing the respective bobbin hangers 19, 20 from the respective rails 11, 12 and then turning them 180 degrees.
The detailed structure thereof is disclosed in Japanese Patent Publication No. 14848/1983 filed by the same applicant of the present invention, and since the shinobi replacement work is not a main part of the present invention, a detailed explanation thereof will be omitted. On the other hand, supplying a full bobbin to the spare bobbin hanger 24 is achieved, for example, by inserting a full bobbin at the roving machine position and moving it together with the bobbin carriage 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, on the lower side of the main body 51 of the Shino exchanger 50, there are wheels 51a,
A guide roller 29 is provided on the side of the main body 51 facing the spinning machine, and a travel motor 21 and a scroll cam 22 that cooperate with the travel motor 21 are provided in the main body 51. On the other hand, the spinning machine spindle rail 26
the guide rail 2 via the mounting bracket 27.
8, and a large number of guide pins 30 are installed on the outer surface of the guide rail 28 at intervals equal to the pitch intervals of the front row bobbin hanger 19. The guide roller 29 is a guide rail 28
By rotating the scroll cam 22 while engaging the guide pin 30 with the scroll cam 22, the Shino changer 50 is moved along the spindle row of the spinning machine;
Moreover, it can be stopped at a predetermined position.

Next, the configuration of the Shino switch 50 will be explained. The Shino exchanger 50 is equipped with various mechanisms for performing Shino joining and Shino exchange in a predetermined order, and drive mechanisms for these mechanisms. That is, six small bobbins 1 on the front row bobbin hanger 19 at a time as illustrated in FIG.
In the replacement machine 50, which replaces the bobbins c with the full bobbins 1a on the six spare bobbin hangers 24 and splices the bobbins 1a, the bobbins are moved up and down by the lifting mechanism 31 disposed in the center, and also move back and forth. Full bobbin exchange head 52 that rotatably supports six pegs
and small bobbin exchange heads 5 which are arranged on both sides of the full bobbin exchange head elevating mechanism 31, are moved up and down by the elevating mechanisms 41a and 41b, and also move back and forth, and each rotatably supports three pegs.
5, and six outlet nozzles 62 which are connected via a hose 23a from the blower 23 housed in the main body 51 of the main body 51 and draw out the small end of a full bobbin by its suction action. The machine is equipped with a shin splicing device 300 consisting of six shin splicing heads 60 for polymerizing the shin of a small bobbin during spinning, and a shin hanging plate 58 for hanging the shin of a full bobbin on a roving guide 2. Figures 1 to 18 below
Each of the above components will be explained with reference to the drawings.

First, the full bobbin exchange head 52 will be explained. The change bar 71 of this full bobbin exchange head 52 has six pegs 53 for the full bobbin exchange head.
is rotatably arranged (Fig. 11). In order to move the full bobbin 1a from the position shown in FIG. 3 to the position of the small bobbin 1c using the peg 53, it is necessary to move the peg 53 up and down and back and forth. The change bar 71, on which six pegs 53 are disposed so as to be closed as shown in FIG. 5, is connected to the full bobbin exchange head lifting mechanism 31 shown in FIG. It is arranged on the upper part of the elevating body 37.
Two vertically parallel chains 36a and 36b are connected to the elevating body 37, and these chains 36a and 36b are connected to a motor 32 for a full bobbin exchange head elevating mechanism disposed in the Shino exchanger 50. The elevating body 37 is moved up and down by moving it both up and down. That is, shaft 3 of motor 32
3 is attached with a chain wheel 33a, and the rotation of this chain wheel 33a is controlled by the chain 33.
b and the chain wheel 34a to the Shino exchanger 5.
The signal is transmitted to a shaft 34 that is rotatably supported by the main body 51 of 0. Chain wheels 3 are attached to both ends of the shaft 34.
5a, 35b are attached, and the aforementioned chain 3 is hung on the chain wheels 35a, 35b.
6a, 36b have one end connected directly below the elevating body 37, and the other end connected above the elevating body 37 via chain wheels 39a, 39b rotatably disposed above the main body 51, Therefore, the vertical movement of the elevating body 37 is achieved by the 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 the 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 the motor 86 of the housing 77 swings the arm 82 through a reducer 85 and gears 84, 83, and the swinging motion is caused by a motor 86 provided at the tip of the arm 82. It is transmitted to the swinging arm 80 through the sliding pin 81 and the elongated hole 80a of the swinging arm 80 with which the sliding pin 81 engages. Housing 7
The lower end of the outer link 76 and a swing arm 80 are fixed to a pin 79 pivotally connected to the outer link 76 . 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. One end of a change bar support member 72 is connected to the upper end of the outer link 76 via a pivot pin 74, 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 in the middle portion of the change bar support member 72, and the upper end of the inner link 75 is connected via this pivot pin 73. The lower end of the inner link 75 is connected to the housing 77 via a pivot pin 78.
Therefore, by the rocking motion of the outer link 76 in the direction of the arrow, the peg 53 on the change bar 71 is moved back and forth with respect to the spinning machine while maintaining its vertical position, and is moved to the position directly below the spare bobbin hanger 24 and in the front row. It can be moved to a position directly below the bobbin hanger 19.

Next, the full bobbin peg 53 in the full bobbin exchange head 52 and its rotation mechanism are shown in FIGS.
This will be explained with reference to FIG. As shown in FIGS. 1 and 11, the change bar 71 of the full bobbin exchange head 52 has six pegs 53 (53a, 53b, 53c, 53d,
53e, 53f) are provided. These pegs 53 are adapted to be rotated in order to unwind and rewind the wire from a full bobbin during the various steps of the wire exchange, as will be explained in detail regarding the operation of the wire exchange later. Furthermore, at the beginning of the cage replacement operation, every other peg 53 can be rotated 180° 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 full bobbin in this embodiment can be brought out smoothly. In other words, the front row and rear row pressers of the flyer on the roving frame have a 180° phase difference between the front row and the rear row, so the front row is different from the rear row. placed on the opposite side 180°. Therefore, if the front and rear rows of full bobbins doffed by a roving frame are rearranged into a row with every other row in between, and the row of full bobbins is suspended from the spare rail 15 using the bobbin carriage 17, these As shown in FIG. 10A, the ends 1ae of the full bobbins 1a are positioned 180 degrees opposite to each other as shown in FIG. 10A. In other words, in FIG. 10A, if the ends 1ae of the full bobbins at positions a, c, and e are located opposite the outlet nozzle 62, the ends 1ae of the full bobbins at positions b, d, and f are Shino no Shinobata 1ae has outlet nozzle 62
is on the opposite side of In this state, when the six full bobbins are returned and rotated all at once in order to be fed by the feed nozzle 62, since the interval between the full bobbins is generally small, the Shinobashi which was located on the opposite side from the feed nozzle 62 is Before reaching the outlet nozzle 62, the thin end may adhere to the circumferential surface of an adjacent full bobbin and be wound around the full bobbin, making it impossible to extract the bobbin. Therefore, at the beginning of the Shino exchange operation, the full bobbins 1a at positions b, d, and f are rotated 180° in the winding direction in advance, and the Shino ends 1ae of the six full bobbins are exposed as shown in Fig. 10B. They are arranged so as to face the 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. As mentioned above, 6 Pezugs 53 are combined into 1
In order to make the book stand rotatable, each peg 53 is rotatably supported by a change bar 71 as shown in FIGS. 11 and 12.
A pulley 162a with three pegs 53a, 53c, and 53e provided below each peg,
162c, 162e, and the other three pegs 53b, 53.
d, 53f are the same pulleys 162b, 162d,
It is made rotatable by a belt 164 via 162f. A motor 5 drives the belts 163 and 164 via drive pulleys 57a and 54a.
7, 54 are mounted on the change bar 71.
In the figure, 161a to 161i are the respective belts 16
This is a guide pulley that guides the 3,164. 1st
As shown in Figure 0, every other full bobbin 1a at positions b, d, and f is moved 180° in the winding direction (clockwise) in advance.
To rotate, the motor 54 is rotated counterclockwise in FIG. 11, and to rotate the entire full bobbin 1a in the unwinding direction (counterclockwise), the motor 54,
57 in the clockwise direction in FIG. 11 at the same time.

As shown in FIG. 13 (corresponding to pegs 53a, 53c, and 53e in FIG. 12), the full bobbin peg 53 has a support shaft 166 rotatably supported by a bearing attached to a change bar 71. A fitting part 166a that can be fitted into and removed from the lower hole of the bobbin is provided at the upper end of the support shaft 166, and a cylindrical bobbin receiver 167 having a collar-shaped receiver part 167a on the outer periphery is provided at the middle part of the support shaft 166. are fitted so as to be movable up and down, and the bobbin receiving body 167 is connected to the support shaft 16.
A spring 169 interposed between spring receiving plates 168 fitted to the base of the spring 6 is biased upward so as to come into contact with the fitting part 166a. The receiving part 167a of the bobbin receiving body 167 is formed to have a larger diameter than the lower hole of the bobbin so as to be able to support the bobbin, and the outer circumference of the upper part of the cylinder of the bobbin receiving body 167 is the same as the fitting part 166a. Alternatively, it is formed to have a small outer diameter 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 changing head 55 be configured to move up and down and back and forth with respect to the spinning machine. The mechanism for this purpose is almost the same as that of the full bobbin exchange head, and the mechanism for providing vertical movement is three small bobbin pegs 56 on each side of the full bobbin exchange head lifting mechanism 31, as shown in FIG. A small bobbin exchange head elevating mechanism 41a, 41b is provided for vertically moving the bobbin. The elevating bodies 47a, 47b of the elevating mechanisms 41a, 41b each have two chains 46a, 46b and 46c, 4 extending in parallel in the vertical direction.
6d are connected, and these chains 46a, 46b,
The elevating bodies 47a and 47b are moved up and down by moving the elevating bodies 46c and 46d in both up and down directions using a small bobbin exchange head elevating mechanism motor 42 disposed in the main body 51 of the Shino exchanger 50. To illustrate the movement of the chains 46a, 46b, 46c, and 46d using the chain 46a as an example, the rotation of the motor 42 is controlled by the chain wheel 43 fixed to the motor output shaft.
a, the rotation of the shaft 44 is transmitted to the shaft 44 through the chain 43b and the chain wheel 44a fixed to the shaft 44, and the rotation of the 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 is similar to that of the full bobbin exchange head 52 shown in FIG.
The peg 56 can be moved to the standby position shown in FIG.
It 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.

Peg 56 in small bobbin exchange head 55
The structure is as shown in Fig. 13.
3, while each Pezg5
The mechanism for rotating the peg 6 is similar to the mechanism for rotating the full bobbin peg 53 shown in FIGS. 11 and 12. However, each of the three pegs 56 of the small bobbin exchange head 55 only needs to be rotated simultaneously in the same direction at all times, so the belt and motor for driving the pegs 56 are required for each of the left and right small bobbin exchange heads 55. It is sufficient to provide one in

Next, the outlet nozzle operating mechanism, the shin joint head operating mechanism, and the shin hooking plate operating mechanism will be explained in order.In the shin exchanger shown in Fig. 1, the operations of the three types of operating mechanisms are three pieces on the same shaft. The operation mechanism 65 is provided by a pair of left and right outlet nozzles, a connecting head, and a connecting plate operating mechanism 65 in which cams are arranged side by side, so this operating mechanism 65 will be explained first with reference to FIG. As shown in FIG. 6, a splicing action cam 66, a pick-up action cam 67, and a thread hooking action cam 68 are fixed side by side to one rotatable cam shaft 93. Each cam 66, 67, 68
Cam follower 94 and cam follower 94 corresponding to
One end of the cam lever 95 is pivotally connected to the main body 51 of the Shino exchanger 50 via a pin 96, and operating rods 97, 98, and 99 are connected to the rotating function at the other end. has been done. 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 threaded joint head and an outlet nozzle are provided. The operating rod 98 and the shank plate operating rod 99 are arranged so as to extend upwardly or downwardly. The rotation of the pair of left and right camshafts 93 is achieved by converting the rotation of the motor 87 arranged in the main body 51 of the Shino exchanger 50 into the rotation of the chain wheel 90 via the reducer 88, chain wheel 89, and chain 91. Long intermediate shaft 90a and mutually meshing gears 92a, 92
This is achieved by transmitting the signal to the left and right camshafts 93 via the camshafts 92b and 92c (the one on the right in FIG. 1 is not shown).

Next, referring to FIG. 7, the outlet nozzle 62 and outlet nozzle operating mechanism of the connecting device 300 will be explained. 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 an outlet nozzle support pipe 139 via a nozzle mounting bracket 138 at its lower end.
from the blower 23 to the hose 23.
The suction airflow reaching both ends of the outlet nozzle support pipe 139 through the outlet nozzle 62 serves to pull out the thin end of the full bobbin 1a from the tip of the outlet nozzle 62.
In order to guide the protruded chisel end to the splicing head 60, the tip of the spout nozzle 62 is moved along a curve shown by a trajectory 140 in FIG.

In addition, in the Shino switching machine 50 shown in FIG.
Six outlet nozzles 62 are individually attached to the support pipe 139 at intervals of the spindle pitch.
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 127 via a gear 124 and a sector gear 125. A parallel guide 132 having two linear rods 133 is disposed in the main body 51 of the Shino exchanger 50, and an upper portion 128 of the slider 128 is provided with a parallel guide 132 having two straight rods 133.
A is provided with a long hole 129, into which a sliding pin 131 provided at the tip of the lifting arm 127 is fitted to be able to swing freely, thereby swinging the lifting arm 127 in the direction of the arrow. and slider 1
28 can be moved up and down along a parallel guide 132. The right end of the slider upper portion 128b is an outlet nozzle support pipe 139.
One end is rotatably supported. Shino exchange machine 5
A guide plate 134 having a curved guide hole 135 that defines the trajectory of the tip of the outlet nozzle 62 is disposed on the main body 51 of the 0.
A sliding pin 136 that engages with is provided at one end of a continuous arm 137, and the other end of the continuous arm 137 is integrally connected to an outlet nozzle support pipe 139. Therefore, when the slider 128 rises, the outlet nozzle 62 itself rises, and the sliding pin 136
is guided along the curved guide hole 135 to rotate the outlet nozzle 62 around the pipe 139, and the tip of the outlet nozzle 62 is rotated around the pipe 139.
It will be moved along the trajectory shown by . It is preferable to provide a comb inside the tip of the outlet nozzle 62 to help cut the wire.

Next, the connecting head 60 of the connecting device 300 and the operating mechanism of the connecting head will be explained with reference to FIG. This Shinotsugu head operating mechanism is also provided symmetrically on the left and right sides. The Shinotsugu head 60 is connected to the outlet nozzle 62.
This device polymerizes the grain end pulled out from the full bobbin into the grain of the small bobbin being spun, and cuts the grain of the small bobbin after polymerization. In the Shino exchanger 50 shown in FIG. 1, six Shino joint heads 60 are arranged on the Shino joint head support bar 148 (see FIG. 17) in correspondence with the aforementioned outlet nozzles 62. As shown in FIG. 8, when the outlet nozzle 62 is suctioning the edge of the sashimi, the shinotigi head 60 is directed vertically downward from the shinotigi head support bar 148 to avoid interference with the outlet nozzle 62. ,
Next, it is necessary to grasp the grain end and rotate it counterclockwise or move it to the right in FIG. 8 in order to overlap the grain with the grain of the small bobbin being spun. The moving mechanism for moving the moving head 60 as shown in FIG. This is a mechanism that rotates the inner link 146 and the outer link 147 clockwise with a time difference provided therebetween.
The inner link 146 and the outer link 147 are connected to the pivot shaft 1
45 to be rotatably supported by the main body 51 of the Shino exchanger 50, and at the same time tension springs 152, 152, respectively.
153 in the counterclockwise direction, and the inner link 146 is received by the stopper 51h. The pivot shaft 145 is rotatably supported by a pair of left and right supports 51e, 51e fixed to the main body 51, and is slightly movable in the longitudinal direction.
The lower end of the inner link 146 is loosely fitted onto the pivot shaft 145, and the lower end of the outer link 147 is fixed. A sector gear 144 is fixed to the end of the pivot shaft 145, and this sector gear 1
44 is a gear 141a integrated with the swing arm 141
It's meshing with. A pin 151 is provided at the upper end of the outer link 147, and the long hole 1 of the connecting link 150
50a.

The upper end of the inner link 146 rotatably supports a pin 149 that is integrally protruded from the end surface of the Shino joint head support bar 148, and the upper end of the connecting link 150 is fixed to the pin 149. The joint head support bar 148 is rotatable about the pin 149 by the rocking of the connecting link 150.

Therefore, by the downward movement of the rod 97 for moving the connecting head, the swinging arm 141 is moved to the pin 143.
When the outer link 147 rotates counterclockwise about the sector gear 144 and the pivot shaft
5 and swings clockwise against the tensile force of the spring 153 to push the pin 151 at the upper end of the outer link 147 to the right and move the connecting link 150 to the pin 14.
Turn counterclockwise around point 9. As a result, the Shinogi head support bar 148 rotates counterclockwise with the Shinogi head 60. This rotational movement is caused by the connecting link 15
0 continues from the position shown in FIG. 8 to the opposite position symmetrical to the vertical line passing through pin 149;
As a result, the Shinotsugu head 60 is in a nearly horizontal position.
Further, when the rod 97 for moving the shading head 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.
Thereafter, the pin 149 is pulled to the right by the connecting link 150 to rotate the inner link 146 about the axis 145, and the horizontally oriented Shinotsugu head 60 follows the trajectory shown at 154. It will then move towards Shino R from the small bobbin that is being spun.

In a spinning machine, the position of the drafting section 5 when a full bobbin is arranged is usually shifted by 1/2 pitch of the spindle of the spinning machine, as shown in FIG. Therefore, when taking out the full bobbin, holding it in the Shino joint head 60, and moving it to the drafting section 5, the Shino joint head 60
It is necessary to move the small bobbin 0 horizontally by 1/2 spindle pitch to the side of the drafting section 5 where the thread of the small bobbin is introduced. Therefore, as shown in FIG.
5 is moved. The Shinotsugu head lateral movement mechanism 61 has a motor 217 with a reducer fixed to the main body 51, a worm 218 rotated by the motor 217, and a worm wheel that meshes with the worm 218. The rod 145 is selectively moved to the right or left in FIG. 1 by the swing of the arm 155.

Next, the structure of the Shino joint head 60 and its operating method will be explained with reference to FIGS. 14 to 17. 14th
The figure shows a plan view of one embodiment of the Shinotsugu head.
Figure 5 shows its side view. Figures 14 and 15
The shown joint head 60 has a main body 171 with a guide groove 173 formed at its tip, and is capable of reciprocating across the guide groove 173 in a plane parallel to the upper surface of the main body 171. Shino grip lever 1
It consists of 74. The main body 171 is fixed to a cylindrical head support bar 148 having a U-shaped cross section. The gripping lever 174 is rotatably supported near the center by a pivot pin 178 fixed to the main body 171, and a pin 179 is protruded from its rear end. As shown in FIGS. 14 and 15, each main body 171 has a cylinder body 186a of one air cylinder 186 in a cylinder unit 188 consisting of a pair of air cylinders 186 and 187 having a common piston rod 185. There is. Cylinder body 186 of the other air cylinder 186 in the cylinder unit 188
a is fixed. The above cylinder unit 18
An actuating member 181 is fixed to the cylinder body 187a of the other air cylinder 187 in 8.
The pin 179 of the Shino grip lever 174 is engaged with the engagement groove 181a provided in the actuating member 181. One of the air cylinders 186 is for rotating the Shino gripping lever 174 from the neutral position shown in FIG. 14B to the full bobbin Shino gripping position shown in FIG. 14C, or vice versa, and the piston chambers 186b on both sides,
Pipes 200a and 200b are connected to 186c. Furthermore, the air cylinder 187 moves the Shino grip lever 174 from the neutral position shown in FIG. 14B to the 14th position.
This is for rotating the small bobbin to the gripping position shown in Figure A or vice versa, and both piston chambers 187b,
Pipes 301a and 301b are connected to 187c. The piping 200a, 200b is connected to a compressed air source 303 via a solenoid valve 302 for each of the connecting heads 60, and the other piping 301a, 300b
1b is the piping 301a, 30 of the other Shino joint head 60
1b and is connected to a compressed air source 303 via a solenoid valve 304. Also, Shino grip lever 17
Nip pieces 176 and 177 each have a gripping surface 176a and 177a facing the tip surfaces 175a and 175b of the nip pieces 176 and 177, respectively, which are fixed to the upper surface of the main body 171 at positions on both sides of the guide groove 173. 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. Groove 17
3 is provided with an opening for a nozzle 18 that emits water in the downward direction.

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. 14A shows a case where a small bobbin shell (not shown) is gripped between the grain gripping surface 175a of the grain gripping lever 174 and a grain gripping surface 177a of the nip piece 177, and a case where a grain of a full bobbin is held in the grain guide groove 173. The position of the Shino grip lever 174 in a standby state for guiding is shown. When the connecting head 60 is positioned in the vertical position described with reference to FIG.
After being introduced into the Shino guide groove 173 through the Shino grip lever 174, the Shino grip part 175 rotates to the right as in the state shown in FIG. After that, while the shin joint head 60 is moved from the vertical position to the horizontal position, the shin between the lead nozzle 62 is cut into a brush tip shape on the downstream side of the gripping point by the shin grip lever 174, and as a result, the shin guide groove 173 A brush tip-like grain end that is to be polymerized with the grain of the small bobbin during spinning is placed inside. In this state, Shinotsugu head 6
0 is brought close to the center 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 in FIG. As a result, the pitch R of the small bobbin being spun introduced into the trumpet 5 is introduced into the thread guide groove 173, and the thread end of the full bobbin is superimposed on the thread R of the small bobbin. Ru. Next, as shown in FIG. 14B, the Shino grip part 175 of the Shino grip 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. It is introduced into the trumpet 6 in a polymerized state. Thereafter, when the thin end of the full bobbin is introduced into the back roller 5a of the drafting section 5, the gripping section 175 is rotated to the left as much as possible as shown in FIG. 14A, and the gripping lever 17
The small bobbin Shino R is gripped between the left gripping surface 175a of the gripping portion 175 of No. 4 and the gripping surface 177a of the left nip piece 177. In this way, the shin on the downstream side of the shin splicing head 60 is spun toward the drafting section 5, so the spliced portion advances downstream, and the shin R upstream of the shin spliced portion is connected to the gripping lever 174 and the left nip piece 177. Since it is held in place, it is pulled and cut to complete the Shinotsugi. Thereafter, the Shino gripping lever 174 rotates to the neutral position, and the holding of the Shino R is released.

In this embodiment, the Shino joint head 60 constitutes a Shino supply stop device 305 capable of stopping the supply of Shino from a full bobbin to the trumpet 6. In the state where the thread is in the thread joining position shown in , the thread gripping portion 175 of the thread gripping lever 174 and the nip piece 176 grasp the full bobbin thread being supplied to the trumpet 6, cut the thread, and insert the thread into the trumpet 6. Shino supply is now being suspended.

FIG. 16 shows another embodiment of the Shino joint head 60. As can be easily seen from the side view shown in FIG. 16B, this Shino splicing head 60 uses two Shino gripping levers: a lever 174a for full bobbin Shino and a lever 174b for Shino R during spinning from a small bobbin. This differs from the Shinotsugi head 60 shown in FIG. 15 in that it is
This Shino joint head 60 cuts the Shino R upstream from the planned polymerization area, and operates in the same manner as the Shino joint head 60 shown in FIGS. 14 and 15 to cut the Shino end of the full bobbin into the small bobbin. Polymerizes into Shino R to complete Shino joint. This Shino joint head 60 also has a Shino supply stop device 3.
05, and the lever 174a and the nip piece 176 are designed to sandwich a full bobbin to cut it.

Next, the inner link 1 of the above-mentioned Shinotsugu head operating mechanism
Both ends of a support bar 306 are fixed to the intermediate portions of the threads 46 and 146, respectively, and the support bar 306 is arranged at a position corresponding to each of the thread joint heads 60 so as to be able to detect thread breakage at each of the thread joint weights. A thread breakage detection device 307 is installed. This thread breakage detection device 307 is composed of a fixed reflection type, transmission type photoelectric type, sonic type, air micrometer type, or other appropriate detector.
When the yarn splicing head 60 is located at the splicing position shown by the imaginary line in FIG. Then, the electromagnetic valve 30 of the thread supply stop device 305 corresponding to the thread cutting generation weight is activated.
2 as shown in Fig. 14C, and press the Shino grip lever 1.
74 and the nip piece 176 are electrically connected to grip a full bobbin. Note that the thread breakage detection device 307 may be attached to a support mechanism provided separately from the Shino splicing head operating mechanism, or may be fixedly attached to the main body 51 of the Shino exchanger 50.

Next, with reference to FIG. 9, the shading plate operating mechanism will be explained. This shank plate operating mechanism is also provided symmetrically in a pair of left and right sides. The Shino hanging plate 58 is a plate for hanging the Shino of a full bobbin after Shino joining has been completed on the roving guide 2, and in order to do so, the Shino hanging plate 58 must be moved along the locus shown by the curve 116 in Fig. 9. In the Shino exchanger 50 shown in FIG. 1, the Shino hanging plate 58 is formed as a single plate extending in the longitudinal direction of the Shino exchanger 50. The shading plate operating mechanism controls the downward movement of the shading plate operating rod 95 by the shading movement cam 68 of the operating mechanism 65 shown in FIG.
1 and the inner link 102, the movement of the link mechanism gives the shading plate 58 a desired locus of movement. That is, sector gear 10
4 is pivotally connected to the main body 51 via a pin 109, and rotates clockwise about the pin 109 by the downward movement of the rod 95 for operating the shank plate, and this movement is caused by the reaction of the sector gear 105. Causes clockwise rotation. This sector gear 1
05 is fixed to a shaft 112 which is rotatably supported by a support 103 attached to the main body 51 and slidably in the longitudinal direction, and the upper end of the link 101 is fixed to this shaft 112. There is. The lower end of the outer link 101 is rotatably connected to a pin 114 a implanted in the connecting link 107 and a pin 115 a implanted in the rear bridge of the support bar 108 . A shaft 1 is attached to the support 103 so as to be rotatable and movable in the axial direction.
17, and one end of the connecting link 106 is connected to the shaft 11.
7 and the other end thereof can be freely rotated around the shaft 112, and the movement of the shaft 112 in the axial direction can be transmitted to the shaft 117. The upper end of the inner link 102 is fixed to this shaft 117, and the lower end of the inner link 102 is connected to the connecting link 107 by a pin 113. A small gear is wedged to a pin 114a implanted in the connecting link 107, and the small gears 114 and 11
5 are engaged. A plate-shaped shin hooking plate 58 is suspended and fixed to the tips of the support levers 108 on both sides (see FIG. 1).Although not shown, when leading a full bobbin shin to the roving guide 2 after shin splicing, There are 6 Vs on the tip side of the Shino hanging plate (on the right side in Figure 9) to regulate the horizontal position of the Shino.
A shaped guide notch is formed. With this configuration, as the sector gear 105 rotates counterclockwise, both the outer link 101 and the inner link 102 rotate counterclockwise, and as the swinging end of the outer link 101 approaches, the outer link 101 and the inner link rotate. 102. Due to the connection length of the connecting link 107, the connecting link 107 is rotated counterclockwise using the pin 114a as a fulcrum, so the tip of the shading plate 58 moves as shown in the trajectory 116 in FIG. When the link 101 reaches the swinging end, the sash hooking plate 58 above the roving guide 2 is tilted towards the machine base to guide the full bobbin into the roving guide 2.

Next, a mechanism for laterally moving the shading plate 58 will be explained. The hooking plate 58 is attached to the claw portion 2b of the roving guide 2 shown in FIG.
In order to move the plate by 20 mm, for example, in order to apply the plate, it is moved by the plate horizontal movement mechanism 59 shown in FIG. The shinokake plate lateral movement mechanism 59 is a motor 1 with a reducer fixed to the main body 51.
17 and the gear 117a by the motor 117
It has a worm wheel at one end that is rotated via a worm 118 and a worm wheel that meshes with the worm 118, and selectively swings to the right or left in FIG. It consists of an arm 119 that moves 112 laterally. As shown in FIG. 9, as the shaft 112 moves laterally, the inner link 102 is simultaneously moved laterally via the outer link 101 and the connecting link 106, so that the thread hanging plate 58 holding the full bobbin thread is also moved laterally. will be moved. This Shinokake plate 5
8 Yokoi move is performed with the Shino hanging plate 58 raised and guiding Shino into the roving guide 2,
As a result, the claw portion 2b of the roving guide 2 is covered with wire.

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 exchanger described later, the movement of the outlet nozzle, the Shino joint head, the Shino hanging plate, and the full (small bobbin) exchange head is carried out in a predetermined order. For this purpose, the motors in the various operating mechanisms are operated in a predetermined order based on commands from the controller 400 disposed in the main body 51 of the Shino exchanger 50, thereby controlling the full bobbin and small bobbin. At the same time as the exchange is carried out, the thread of the full bobbin is transferred to the thread of the small bobbin that is currently being spun, and when thread breakage occurs during the thread connection, the thread of the full bobbin at the thread cutting weight is transferred to the thread of the trumpet 6. Cut at the top. 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 machine 50 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 FIG. 3, as spinning progresses, the bobbin suspended from the front row bobbin hanger 18 of the creel of the spinning machine becomes a small bobbin 1c, and the bobbin suspended from the rear row obin hanger 20 becomes a medium bobbin. When the bobbin 1b is obtained, 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 mounted on the spinning machine. By this time, the full bobbin 1a is suspended in advance from a spare bobbin hanger 24 arranged on the spare rail 15 of the spinning machine, facing the position of the bobbin hanger 19 in the front row of the spinning machine. 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 positions corresponding to the six small bobbins 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.

First of all, the small bobbin 1c in the front row has less remaining sinter and is in a state where the sinter needs to be replaced (FIG. 17, 1). When this state is reached, Fig. 17 2
The bobbin hanger 2 of the spare rail 15 as shown in
The full bobbin exchange head 52 corresponding to the position directly below the full bobbin 1a suspended from the full bobbin 1a is raised by the elevating mechanism 31, and the peg 53 of the full bobbin exchange head 52 fits into the lower part of the full bobbin 1a, and the full bobbin 1a is removed. from the bobbin hanger 24. The full bobbin exchange head 52 carrying the full bobbin 1a is lowered and returned 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 position of the thin end of the lowered full bobbin 1a (FIG. 17, 3). Next, the motor 54 of the peg rotation mechanism built into the full bobbin exchange head 52 rotates counterclockwise when viewed from above, and pre-winds every other full bobbin whose end is on the opposite side from the outlet nozzle 62. The bobbins are rotated 180° in the taking direction, 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 rewinding direction, and the suction by the blower 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. 17, 4). While continuing the rotation of the full bobbin 1a and the suction by the outlet nozzle 62, the outlet nozzle 62 descends and returns to its original position, and at this time, the tapped out Shino enters the Shino guide groove 173 of the Shino joint head 60 (Fig. 17). 5). In this case, the electromagnetic valves 302 and 304 for operating the Shinotsugu head 60
is in the state shown in FIG. 14B, and after Shino enters the Shino guide groove 173 as described above, the electromagnetic valve 30
2, 304 is operated to the state shown in FIG.
A full bobbin is gripped between the nip piece 176 and the nip piece 175 of 74, and at the same time, the thread joint head 60, which was in a downward vertical position, is brought to a sideways, substantially horizontal state by the shaft joint head operating mechanism, and at this time the full bobbin is held. The thread 1a is caught by a comb mounted inside the tip of the outlet nozzle 62, and is cut between the gripping point in the thread joint head 60 and the outlet nozzle 62 to form a thread end (FIG. 17, 6). Next, the thread joint head 61 moves forward toward the drafting section 5 of the spinning frame by the thread joint head operating mechanism while gripping the full bobbin thread on which the thread edge has been formed. The shinotsugu head 60 temporarily stops advancing while moving forward, and is moved by the shinotsugu head lateral movement mechanism 61 to the 1/2 spindle pitch toward the trumpet 6 side (the right side in the case of Fig. 4) where the shin of the small bobbin is introduced. The drafting section 5 of the spinning machine
The spinning machine assumes a position in the longitudinal direction corresponding to the upstream trumpet 6, and then resumes forward movement until the end of the full bobbin reaches the top of the trumpet 6. At that time, the Shinotsugu head 60 of the small bobbin during spinning
It enters the Shino guide groove 173 and overlaps the Shino of the full bobbin. When the Shino joint head 60 moves forward, the full bobbin is rotated counterclockwise by the peg rotation mechanism of the full bobbin exchange head 52 to unwind the Shino, thereby unwinding the Shino that is generated by the forward movement of the Shino joint head 60. In order to prevent cutting and at the same time to hold the slack of the unwound shin, the shin hanging plate 58 is slightly raised by the shin hanging plate operating mechanism. After the Shino joint head 60 stops moving forward, the electromagnetic valves 302 and 304 for operating the Shino joint head 60 are switched as shown in FIG. The grip of the bobbin 1a is released, and the free bobbin 1a is guided by the bobbin of the small bobbin being spun and inserted into the trumpet 6 together with the bobbin, and the tip of the full bobbin 1a is moved to the back roller of the drafting section 5. 5a, the electromagnetic valve 304 for operating the Shino joint head 60 is switched as shown in FIG.
Grip the small bobbin Shino between the Since the thread of the small bobbin is held by the thread splicing head 60, it is drafted and cut between it and the back roller (FIG. 17, 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 peg rotation mechanism of the full bobbin exchange head 52 rotates the full bobbin 1a counterclockwise to unwind the thread, prevent the thread from being cut due to the rise of the full bobbin 1a, and at the same time hang the thread. The plate 58 further rises close to the roving guide 2 and holds the slack of the fully unwound bobbin 1a. During this time, the electromagnetic valve 304 for actuating the Shino joint head 60 is switched again as shown in FIG. 14B to move the Shino gripping lever 174 to the neutral position. This releases the grip of the small bobbin by the grip lever 174. On the other hand, when the splicing head 60 is moved to the splicing position shown in FIG. When the thread cutting device 307 is positioned facing the road and then performs the thread splicing operation as described above, the thread cutting detection device 307 is in a state where it can determine whether or not there is thread cutting at each thread splicing weight. If thread breakage occurs at least before the Shino-tsugi part is wound around the spindle bobbin,
The thread detection device 307 detects the thread breakage, and based on the detection signal, the electromagnetic valve 3 of the Shino supply stop device 305 (Shino splicing head 60) corresponding to the weight where the thread breakage occurs.
02 is switched and operated as shown in FIG. 14C. As a result, compressed air is supplied to the right piston chamber 186b of the air cylinder 186, and the Shino grip lever 174 is moved from the neutral position shown in FIG.
The full bobbin wire is rotated to the full bobbin wire gripping position shown in FIG.

Thereafter, the thread connecting head 60 moves back to a position where the thread of a full bobbin with no thread cut occurs and comes off the thread guide groove 173 (FIG. 17, 8), and stops. Therefore, the full bobbin holder gripped by the gripping lever 174 and the nip piece 176 as described above is pulled and cut between the gripping portion and the trumpet 6. Furthermore, Shinotsugu head 6
If there is a long time between the retraction of the bobbin 0 and the gripping of the full bobbin by the gripping lever 174, the full bobbin will be cut off by being drawn into the trumpet 6 before the retraction of the connecting head 60. Therefore, even if the supply of the full bobbin wire to the trumpet 6 at the thread cutting generation weight is stopped and the thread trimming state of the weight is left for a long time, there is no risk of the wire winding around the roller. Thereafter, the electromagnetic valve 302 of the sinter supply stop device 305 is switched again as shown in FIG. 14B, and as a result, the sinter gripping lever 174 is rotated to the neutral position to release the grip of the full bobbin.

Next, the small bobbin exchange head 55 advances and rises to a position directly below the small bobbin in the front row of the creel by means of the forward and backward movement mechanism and the elevating mechanism, and removes the small bobbin 1c from the bobbin hanger 19 in the front row (FIG. 17, 9).
The small bobbin exchange head 55 carrying the small bobbin is lowered (FIG. 17, 10), and then retreated to return to its original position. (Figure 17, 11). Small bobbin exchange head 55
The small bobbin is rotated clockwise when viewed from the top by the peg rotation mechanism built into the machine, and the cut wire is wound up. At the same time as the small bobbin exchange head 55 returns to its original position, the full bobbin exchange head 52 descends and returns to its original position. At this time, the peg rotation mechanism of the full bobbin exchange head 52 rotates the full bobbin 1a by an appropriate amount in the clockwise direction to wind up the wire and properly maintain the slack of the wire caused by the lowering of the full bobbin exchange head 52. The shading plate 58 is moved laterally by the shading plate lateral movement mechanism 59 which has been raised to the maximum extent, and the shin of the full bobbin 1a is passed through the roving guide 2 installed in the spinning machine and returned 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. 17, 12). After retreating, the Shinotsugu head 60 is returned from a substantially horizontal state to a vertical state (see FIG. 17).
3). The full bobbin exchange head 52 moves forward to just below the bobbin hanger 19 in the front row, rises, and attaches the full bobbin 1a to the bobbin hanger 19. At this time, the peg rotation mechanism of the full bobbin exchange head 52 rotates the full bobbin 1a by an appropriate amount in the clockwise direction to appropriately maintain the slackness of the sag caused by the forward movement and elevation of the full bobbin exchange head 52. The rear movable small bobbin exchange head 55 is attached to the spare bobbin hanger 2 of the spare rail 15.
4, go up and attach the bobbin hanger 2.
Attach the small bobbin to 4. Shinokake plate 58
descends and moves laterally on the way and returns to the original position (No. 17)
Figure 14). 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. 17, 15).

In this way, one cycle of the thread changing operation is completed, and the thread changing machine 50 moves by six bobbin hangers 19 in the front row and then stops, and the thread changing operation is sequentially repeated from one end of the spinning frame to the other end.

The Shino exchange machine 50 may perform the Shino exchange and Shino joint work in the following procedure. After raising the full bobbin exchange head 52 and fitting the full bobbin 1a into the peg 53 (FIG. 17, 2). Advance the small bobbin exchange head 55,
Raise it up, remove the small bobbin 1c from the front row bobbin hanger, and return to the original position. The full bobbin 1a and the small bobbin 1c are in the positional relationship shown in FIG. 17 and the small bobbin 1c is spun. Next, the full bobbin exchange head 52 is lowered, and the thread end of the full bobbin 1a is gripped by the thread splicing head 60 and guided above the trumpet to perform thread splicing in the same manner as described above. After the Shino-joining is completed, hang the full bobbin 1a on the front row bobbin hanger 19,
The small bobbin 1c is suspended from a spare bobbin hanger 24 of a spare rail after winding up the thread hanging from the roving guide 2.

In this way, when the small bobbin 1c being spun is placed on the peg 56 of the small bobbin exchange head 55 and the shin splicing is performed, the shino being spun from the small bobbin 1c to the roving guide 2 is connected to the small bobbin. Bobbin 1
Rotate the small bobbin 1c counterclockwise to give an appropriate amount of slack so as not to interfere with the full bobbin 1a in front of c, and rotate the small bobbin 1c at a speed equivalent to the amount of spin of the shin until the shin splicing work is completed. It is necessary to continue unwinding and rotating. However, according to this method, when replacing the full bobbin 1a and the small bobbin 1c after the completion of the thread joining in the embodiment shown in FIG. 17, the full bobbin 1a is retracted upward to avoid interference between both bobbins (see FIG. Operation of full bobbin 1a from 9 to 11)
can be omitted.

In this embodiment, since the Shino joint head 60 is provided so as to correspond to the center of the full bobbin 1a, the Shino joint head 60 is moved laterally by 1/2 spindle pitch while it is moving forward, so that it corresponds to the center of the trumpet 6. However, this 1/2 spindle pitch lateral movement is performed on the same spinning machine, and is first moved to the left side, and then moved to the right side when the next thread is replaced. That is, it goes without saying that the spinning head 60 is guided above the trumpet 6 on the side where the small bobbin 1c is spinning by alternating left-lateral movement and right-lateral movement. The Shinotsugu head 60 and outlet nozzle 62 are designed so that they can be moved laterally by the spindle pitch.
By protruding the cut end of the full bobbin 1a at a position corresponding to the trumpet 6, it becomes unnecessary to perform a lateral movement during the forward movement of the cutter joint head 60. In this case, before taking out the cutting edge from the full bobbin 1a, the cutting head 60 and the cutting nozzle 62 are connected.
Trumpet 6 is spun by small bobbin 1c.
It must be moved in advance to a position corresponding to . In addition, when the outlet nozzle 62 is placed at a position corresponding to the trumpet 6 and the Shinotsuki head 60 is positioned so that it can move laterally by the spindle pitch, the lateral movement of the Shinotsuki head 60 during its forward movement is the same as the lateral movement by the spindle pitch. You will be alternating between no and no. Furthermore, when the suction airflow of the lead-out nozzle 62 is made to generate a swirling airflow in the direction opposite to the direction of twisting the wire, the wire ends drawn into the lead-out 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, moquette, or the like. If the suction port of the outlet brush and outlet nozzle 62 is designed to be able to be raised and lowered from the standby position of the Shino exchanger 50 to a position facing the outer periphery of the full bobbin 1a suspended on the spare rail, the suction port of the outlet brush and the outlet nozzle 62 can be raised and lowered. It would be fine if the thread end of the full bobbin 1a is exposed and the thread is spliced, and after the thread splicing is completed, the small bobbin 1c is removed and the thread is replaced. Therefore, the Shino switching device 50 becomes large. Further, in the above embodiment, after the thread splicing, the thread of the small bobbin being spun is gripped by the thread gripping lever 174 and the nip piece 177, and the thread is pulled and cut by the spinning of the back roller 5a. The present invention may also be implemented by arranging the lower surface of the shinobi gripping lever 174 and the upper surface of the nip piece 177 of the above embodiment to rub against each other, so that the underside of the shinobi gripping lever 174 and the upper surface of the nip piece 176 cut the shinobu like scissors. It's not something to deviate from. Also, the Shino guide groove 17 of the Shino grip lever 174
The reciprocating movement across 3 may be performed by fixing the Shino grip lever 174 to the actuating bar 182 and moving it in parallel. In addition, the Shino grip levers 174 of the plurality of Shino joint heads 60
When the two are actuated by the same actuating bar 182, a spring may be interposed between the holding lever 174 and the actuating bar 182 so that the holding of each holding head 60 is reliably performed.

In addition, in the present application, the Shino supply stop device is provided in the main body of the Shino exchanger separately from the Shino joint head, and when the thread cutting detection device detects a thread cut during Shino splicing, each Shino supply stop device is set above the trumpet. After that, the thread supply stop device corresponding to the thread trimming weight grasps the full bobbin thread, and then the thread supply stop device moves back to cut the full bobbin thread between it and the trumpet, and then the full bobbin thread is removed. You may release the grip. Alternatively, each thread supply stop device may be configured to move back and forth independently, so that only the thread supply stop device corresponding to the thread trimming weight moves above the trumpet to cut the full bobbin thread. Further, the rotation of the shim gripping lever of the sash supply stop device may be performed by a solenoid, or the full bobbin sash may be suctioned and held by a suction air flow to be cut. Furthermore, the exchange of a small bobbin and a full bobbin in the present application is not limited to the above embodiment, and as shown in the specification and drawings of Japanese Patent Application No. 60-198593, the exchange of a small bobbin and a full bobbin may be performed by inserting the bobbin into the bobbin hangers in the front and rear rows of the creel. In front of the small bobbin,
The latter two are taken out to the spare bobbin hanger in advance, and then the two full bobbins inserted into the spare bobbin hanger are inserted into the front and rear row bobbin hangers after being taken out. May be implemented.

Effects of the Invention As described above, according to the present invention, the thread exchanger is equipped with a lead-out nozzle and a thread joint head, and when replacing the thread, the thread end of a full bobbin is taken out and the thread end is transferred to the drafting section. Since the supply and the supply of the small bobbin wire are stopped, the wire connection work can be automatically performed when replacing the wire, resulting in significant labor savings. In addition, the Shino exchanger itself is equipped with a thread cutting detection device that detects thread cutting at the Shino connecting weight, and a Shino supply stop device that stops Shino supply.
If a thread breakage occurs due to a mistake in thread joining, the supply of thread at the weight where the mistake occurred is immediately stopped, so even if the thread is spliced using a thread exchanger, it will almost never occur. At the same time, the supply of Shino can be stopped, and it is possible to reliably prevent the weight from being wrapped around the roller in the case of a mistake in Shino joining, which eliminates machine damage accidents and waste of Shino, making it possible to unattend the Shino joining and Shino change work. Furthermore, the Shino supply stop device can be provided in the Shino joint head, and the configuration of the device can be extremely simplified.
