Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a sash exchanger for a spinning machine, and more specifically, a sash exchanger that mechanically performs sash exchange when exchanging a small bobbin and a full bobbin. It concerns switching equipment.

Conventional technology & 3 Previously, in order to mechanize the replacement work, Japanese Patent Application Laid-Open No. 58-81
As shown in No. 631 and Japanese Unexamined Patent Publication No. 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.

However, the above-mentioned Shino exchange machine only exchanges the small bobbin and the full bobbin sequentially from one end of the spinning machine to the other end, and the connection between the small bobbin Shino and the full bobbin Shino still has to be done manually. However, there was a problem in that it required a lot of labor to perform the replacement. Therefore, the applicant of the present application has developed a shino-joining device that also performs shino-joining when exchanging the shino, and has filed a bamboo permit application under Japanese Patent Application No. 193919/1983. This thread connection device is designed to allow the thread end to come out from the full bobbin that is to be replaced.

Problems to be Solved by the Invention In the above-mentioned Shino exchange machine, it is possible to perform Shino replacement as well as Shino joining, and it is possible to mechanize the Shino replacement work. If a thread break occurs on the thread exchange weight when replacing the thread, manual handling of the thread cut will be delayed, and the thread of the thread trimming weight may wrap around the draft roller, causing machine failure. There was a fear that Shino would be wasted. Particularly in recent years, spinning machines have tended to have more spindles, and when yarn breaks during splicing, it takes longer for workers to splice the yarn manually, which is a problem that can easily lead to accidents due to the thread being wrapped around the rollers. There was.

Means for Solving the Problems Therefore, in order to solve the above-mentioned problems, the present invention places a full bobbin in advance at a standby position provided along the creel, and when the Shinomaki bobbin of the creel becomes a small ball, the spinning machine In the Shino exchange machine, which moves along the front of the stand and is configured to exchange the small bobbin and full bobbin one after another, the small bobbin is fed with the Shino end from the full bobbin to be replaced and the Shino end is supplied to the trumpet. A thread cutting device configured to connect threads to threads, a thread cut detection device configured to detect thread breakage in a thread threaded weight, and a thread cutter detection device capable of stopping the supply of a full bobbin to a thread trumpet in the thread threaded weights. and a Shino supply stop device configured such that when the thread cut detection device Nα5 detects a thread cut in the Shino joint weight, the Shino supply stop device stops the Shino supply to the Shino joint weight. It is characterized by becoming.

When the Shino bobbin of the working creel becomes a small bobbin, the Shino changer moves along the front of the spinning machine stand, stops at a position corresponding to the first Shino change weight, and at that position, the Shino bobbin of the creel and the small bobbin of the creel are placed in a waiting position in advance. Replace the fully placed bobbin. When replacing the thread, the thread joining device operates to take out the thread end of the full bobbin and join the thread end to the thread of the small bobbin being supplied to the trumpet. If a thread break occurs due to some reason in that Shino connection weight, the thread cut detection device detects the thread cut and activates the Shino supply stop device to stop the supply of Shino of the full bobbin at that thread cut occurrence weight. do.

It is arranged like this. 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 roving guide 2 in the form of an abbreviated Nα7 ring is supported below the middle of the front and rear bobbin hangers 19, 20 by a support rod 9 on the creel pillar 4. As shown in FIG. 4, this roving guide 2 is formed into a ring shape having an opening 2c, and has a raised portion 2a projecting inward on the side opposite to the opening 2c, and a raised portion 2a extending upwardly on both sides adjacent to the opening 2C. A protruding claw portion 2b is provided. 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.

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 frame. This preliminary rail 15 is formed into a hollow columnar body with a mouth-shaped cross-section 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 IC is also suspended after the replacement work. I can do it.

After being supplied to the back roller 5a, the yarn is guided to the yarn guide 308, heated by the spindle 25, and formed into a 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. 3 while the medium and small bobbins are suspended, respectively.
As a result, the bobbin arrangement shown in Fig. 3 is obtained, and then the thread exchange with thread joining is performed again. The above-mentioned thread exchange is accomplished by rotating each bobbin hanger 19.20 180'' after removing it from its respective rail 11.12.The detailed structure is disclosed in Japanese Patent Publication No. 60-14848 by the same applicant as the present invention. 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, as an example, the supply of full bobbins to the spare bobbin hanger 24 is carried out by replacing the full bobbins at the roving machine position. This is achieved by inserting the bobbin 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, the lower side of the main body 51 of the Shino exchanger 50 includes an axle 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.

The bobbin exchange head 52 and the small bobbin exchange are disposed on both sides Nα11 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, each rotatably supporting three bets. It is equipped with a head 55, and
Six outlet nozzles 62 are connected via hoses 23a to a blower 23 housed in the main body 51 of the machine exchanger, and use their suction action to draw out the thin end of a full bobbin, and to extract the thin end of a full bobbin from the small bobbin being spun. The present invention is equipped with a sash joining device 300 consisting of six sash joining heads 60 for superimposing the sash on the sash, and a sash hook plate 58 for hanging the sash of a full bobbin on the roving guide 2. The respective constituent elements will be explained below with reference to FIGS. 1 to 18.

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 peg 53 up and down and back and forth. The changer 71, in which six begs 53 are disposed so as to be closed as 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 it in both up and down directions using a motor 32 for a full bobbin exchange head elevating mechanism disposed inside the head. 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. It is connected to the upper part of the lifting body 37 via chain wheels 39a and 39b which are rotatably arranged above, and therefore, vertical movement of the lifting body 37 is achieved by rotation of the shaft 34. At that time, the elevating body 37 is a guide member 38a provided perpendicularly to the main body 51.
, 38b, so that accurate movement in the vertical direction is ensured. Next, the full bobbin exchange head 52
The back-and-forth movement is performed 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 a motor 86 in the housing 77 swings the arm 82 through a reducer 85 and gears 84 and 83, and the swinging motion is produced by a motor 86 provided at the tip of the arm 82. It is transmitted to the swinging arm 80 through the sliding bin 81 and the elongated hole 80a of the swinging arm 80 with which the sliding bin 81 engages. A lower end of the outer link 76 and a swing arm 80 are fixed to a pin 79 pivotally connected to the housing 77 . Thereby, the reciprocating rotational movement of the drive gear 84 in the direction of the arrow is caused by the swinging arm 8
0 and causes a rocking movement of the outer link 76 in the direction of the arrow. One end of the changer support member 72 Nα14 is connected to the upper end of the outer link 76 via a pivot pin 74, and the changer 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 the inner link 75 is connected to the housing 77 via a pivot pin 78. Therefore, by the swinging motion of the outer link 76 in the direction of the arrow, the beng 53 on the changer 71 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 19. It is designed so that it can be moved to a position directly below the .

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 changer 71 of the full bobbin exchange head 52 has six pegs 53 (53a, 53b, 53
c, 53d, 53e, 53f) are provided. These pegs 53 are designed to be rotated in order to unwind or wind up the wire from a full bobbin in the various steps of the wire exchange, as will be explained in detail Nα15 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 position of the presser of the flyer on the roving machine is 180 degrees out of phase between the front row and the rear row, so the front row is different from the rear row. They are placed 180° on opposite sides. 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, The Shino end 1ae of Shino 1a of these full bobbins is shown in Figure 10 (A).
As shown in the figure, every other one is located 180° on the opposite side.

That is, in FIG. 10 (A), (a), (Q), (e
), when the end lae of the full bobbin is in a position opposite to the outlet nozzle 62, (b), (d)
, and (f), the tip end 1ae of the full bobbin is on the opposite side of the outlet nozzle 62. 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, the gap between the full bobbins is generally small, so the Shinobashi located on the opposite side from the feed nozzle 62 is used as the feed nozzle. By the time it reaches 62, the threaded end may adhere to the circumferential surface of the next full bobbin and be wound around the full bobbin, making it impossible to take out the thread.

Therefore, at the beginning of the Shino exchange operation, the full bobbin 1a in the positions (b), (d), and (f) is rotated 180° in the winding direction so that six Align the full bobbin Shinobata 1ae to face the outlet nozzle 62,
After that, 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 shown in FIGS. 11 and 12, each peg 53 is
are rotatably supported by the change par 71, and three of the bets 53, 53a, 53c, and 53e, are provided below the respective pulleys 162a, 162.
c and 162e, and the other three pegs 53b, 53d, and 53f are connected to the belt 16 through pulleys 162b, 162d, and 162f.
4 to enable rotation. And the belt 163.
Motors 57 and 54 for driving 164 via drive pulleys 57a and 54a are mounted on changer 71.

In the figure, 161a to 1611 are respective belts 163.1
This is a guide pulley that guides 64. To rotate every other full bobbin 1a at positions (b), (d), and (f) by 180° in the winding direction (clockwise) as shown in FIG. 10, the motor 54 is rotated as shown in FIG. In order to rotate counterclockwise and rotate the entire full bobbin 18 in the unwinding direction (counterclockwise), the motors 54 and 57 may be simultaneously rotated clockwise at the 111m.

As shown in FIG. 13 (corresponding to pegs 53a, 53c, and 53e in FIG. 12), the Nα18 full bobbin peg 53 has a support shaft 166 rotatably supported by a bearing attached to the changer 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 receiving body 167 having a flange-like receiving part 167a on the outer periphery is provided at the middle part of the support shaft 166. The spring 1 is fitted in a vertically movable manner and is interposed between the bobbin receiving body 167 and a spring receiving plate 168 fitted to the base of the support shaft 166.
69 is configured to be biased upward so as to come into contact with the fitting portion 166a. Receiving portion 167 of the bobbin receiving body 167
a 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 periphery of the cylindrical portion of the bobbin receiving body 167 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 to configure the small bobbin exchange head 55 to move up and down and back and forth relative to Nα19 in the spinning machine. The mechanism for this purpose is approximately the same as that for the full bobbin exchange head, and the mechanism for providing vertical movement is three small bobbin pegs 56 on both sides 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 and 47b of the elevating mechanisms 41a and 41b each have two elevating bodies 47a and 47b extending in parallel in the vertical direction.
The book chains 46a, 46b, 46c, 46d are connected, and the chains 46a, 46b, 46c, 46d are moved upwardly and downwardly using a small bobbin exchange head lifting mechanism motor 42 disposed inside the main body 51 of the Shino exchanger 50. By moving the elevating bodies 47a, 47b up and down. Taking the chain 46a as an example to illustrate the movement of the chains 46a, 46b, 46c, and 46d, the rotation of the motor 42 is passed through the chain wheels 43a and 43b fixed to the motor output shaft, and the chain wheel 44a fixed to the passing shaft 44. 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 as shown in FIG.
The peg 56 can be moved to a standby position shown in FIG. 3, a position directly below the spare bobbin hanger 24, and a position directly below the front bobbin hanger 19, respectively. That's how it is.

The structure of the pegs 56 in the small bobbin exchange head 55 is the same as the structure 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 5 for full bobbin
It is similar to the rotation mechanism in No. 3. However, each of the three pegs 56 of the small bobbin exchange head 55 only needs to be rotated simultaneously in the same direction, so the belt and motor for driving the pegs 56 are one for each of the left and right small bobbin exchange heads 55. All you need to do is provide one.

Next, the outlet nozzle operating mechanism, the Shinogake head operating mechanism 21 structure, and the Shinokake plate operating mechanism will be explained in order.
In the Shino exchange machine shown in the figure, the three types of operating mechanisms are operated by a plate operating mechanism 65 for the pair of left and right outlet nozzles, Shino joint head, and Shino hook, in which three operating cams are arranged in parallel on the same shaft. First, this operating mechanism 65 will be explained with reference to FIG. 6. 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 each cam 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, and the other end is Operating rods 97, 98, and 99 are rotatably connected to the . Although only one cam follower 94 and one cam lever 95 are shown in FIG. 6, cam followers and cam levers are provided corresponding to the respective operating cams 66, 67, and 68, and a rod 97 for operating the shinoni head,
The outlet nozzle operating rod 98, Nα22, and shinokake are arranged such that the plate operating rod 99 extends upward or downward. The left and right pair of camshafts 93 are rotated by a motor 87 located inside the main body 51 of the Shino exchanger 50.
The rotation is the rotation of the chain wheel 90 via the reducer 88, the chain wheel 89, and the chain 91, and the rotation is the rotation of the long intermediate shaft 90a and the gears 92 that mesh with each other.
This is achieved by transmitting the signal to the left and right camshafts 93 via the camshafts 92a, 92b, and 92c (the one on the right in FIG. 1 is not shown).

Next, referring to FIG. 7, the outlet nozzle 6 of the Shinotsugi device 300
2 and the outlet nozzle operating mechanism 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 fixedly connected to the outlet nozzle support pipe 139 via a nozzle mounting bracket 138 at the lower end thereof, and the outlet nozzle 62 is fixedly connected to the outlet nozzle support pipe 139 by the suction airflow that reaches both ends of the outlet nozzle support pipe 139 from the blower 23 via the hose 23a. It plays the role of pulling out the thin end of the full bobbin 1a from the tip of the rod 23. In order to guide the protruded chisel end to the splice head 60, the tip of the spout nozzle 62 is moved along a curve shown by a locus 140 in FIG. 7.

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 pitches.

It can be moved up and down along the

The right end of the lower slider portion 128b rotatably supports one end of the outlet nozzle support pipe 139. The main body 51 of the Shino exchanger 50 has a guide plate 13 having a curved guide hole 135 that defines the trajectory of the tip of the outlet nozzle 62.
A sliding pin 136 that engages with this curved guide hole 135 is provided at one end of a connecting arm 137, and the other end of the connecting 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, causing the outlet nozzle 62 to rotate around the pipe 139, so that the tip of the outlet nozzle 62 is moved along the trajectory shown at 140.

It is preferable to provide a comb inside the tip of the outlet nozzle 62 to help cut the wire.

Next, with reference to FIG.
and the operation mechanism of the Shinotsugu head will be explained. The Nα25 Shinotsugu head operating mechanisms are also provided symmetrically in pairs on the left and right. The thread joint head 60 is a device that superposes the thread end pulled 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 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 above-mentioned outlet nozzles 62. As shown in FIG. 8, when the outlet nozzle 62 is suctioning the edge of the Shinogi, the Shinotsugi head 60 is directed vertically downward from the Shinotsugi 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 Shinotsugu head operating mechanism that provides such movement to the Shinotsugu head 60 is the operating mechanism 6 shown in FIG.

0 is engaged with the long hole 150a.

The upper end of the inner link 146 supports the Shinotsugu head/<-1
A pin 149 integrally protruding from the end surfaces of 4 and 8 is rotatably supported, and the upper end of the &27 connection link 150 is fixed to the pin 49, thereby connecting the Shinotsugu head support bar 148. By swinging the link 150, it can rotate about the pin 149.

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 153 via the sector gear 144 and the pivot shaft 145.
The outer link 147 swings clockwise against the tensile force of the outer link 147.
Push the pin 151 at the upper end 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 connecting head 60 is in a substantially horizontal position.

Furthermore, when the rod 97 for operating the Shinotsugu head moves downward and the outer link 147 further rotates clockwise, the pin 15
1 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, causing the inner link 146 to rotate around the shaft 145, and as a result, the horizontally oriented Shinotsugu head 60 moves along the trajectory shown at 154 to rotate the small beads being spun. It will proceed towards Shino R from bobbin 1c.

The position of a full bobbin in a spinning machine and the position of the drafting section 5 are usually shifted by 172 pitches of the spindle of the spinning machine, as shown in FIG. Therefore, when a fully loaded bobbin is taken out, held by the thread joint head 60, and moved to the drafting section 5, the thread of the small bobbin to be jointed is introduced into the drafting section. It is necessary to move the spindle horizontally by 1/2 spindle pitch to the 5 side. Therefore, as shown in FIG.
5 is to be moved. The Shinotsugu head lateral movement mechanism 61 includes a motor 217 with a reduction gear fixed to the main body 51,
Worm 21 rotated by its motor 217
8, and an arm 155 which has a worm wheel that engages with the worm 218 and is swung around a pin 155a as a center, and the swiveling of the arm 155 selectively moves the rod 145 to the right or left in FIG. It is designed to be moved to

Next, the structure of the Shinotsugi head 60 and its operating method will be explained with reference to FIGS. 14 to 17.6 FIG. 14 shows a plan view of an embodiment of the Shinotsugi head, and FIG. Show the diagram. The Shinogi head 60 shown in FIGS. 14 and 15 has a Shinogi head body 171 with a Shino guide groove 173 formed at its tip, and a Shinogi head body 171 that traverses the Shino guide groove 173 in a plane parallel to the upper surface of the main body 171. Shino grip lever 1 that can be reciprocated
It consists of 74. The main body 171 is fixed to a cylindrical head support bar 148 having a U-shaped cross section. Shino grip lever 1
74 is rotatably supported near the center by a pivot pin 178 fixed to the main body 171, while a pin 1 is attached to the rear end.
79 is provided protrudingly.

As shown in FIGS. 14 and 15, each main body 171 includes a cylinder unit 188 consisting of a pair of air cylinders 186 and 187 having a common piston rod 185.
No. 6 cylinder body 186a is fixed. The other air cylinder 18 in the cylinder unit 188
No. 6 cylinder body 186a is fixed. The other air cylinder 18 in the cylinder unit 188
An actuating member 181 is fixed to the cylinder body 187a of No. 7, and a pin 179 of the above-mentioned Shino grip lever 174 is engaged with an engagement groove 181a provided in the actuating member 181.

One of the air cylinders 186 is connected to the Shino grip lever 174.
The piston chambers 186b and 186c on both sides are provided with piping 20.
0a and 200b are connected. The air cylinder 187 is used to rotate the Shino gripping lever 174 from the neutral position shown in FIG. 14(B) to the small bobbin Shino gripping position shown in FIG. 14(A), or vice versa. 1
Pipes 301a and 301b are connected to 87b and 187c. The piping 200a, 200b is connected to a compressed air source 303 via a solenoid valve 302 for each Shinotsugi head 60, and the other piping 301a, 301b is connected to a solenoid valve 303 together with the piping 301a, 301b of the other Shinotsugi head 60.
04 to a compressed air source 303. In addition, nip pieces 176 and 177 having respective gripping surfaces 176a and 177a facing the tip surfaces 175a and 175b of the gripping lever 174 are fixed to the upper surface of the main body 171 at positions on both sides of the gripping groove 173. . Main body 1
A triangular-shaped Shino guide opening 172 is formed at the tip of the Shino guide groove 173 for guiding the Shino into the Shino guide groove 173, and on one side of the Shino guide opening 172, the air sent through the conduit 184 is directed to the Shino guide groove. Nozzle 1 that ejects water to the bottom of 173
8 openings are provided.

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 the Shino gripping surface 175a of the Shino gripping lever 174 and the Shino gripping surface 17 of the nip piece 177.
7a shows the position of the grain gripping lever 174 in a standby state for gripping the grain of a small bobbin (not shown) and for guiding the grain of a full bobbin to the grain guide groove 173. Shinotsugu head 60
In the state where the shin joint head 60 is positioned in the vertical position as described with reference to FIG. At the top, the Shino gripping lever 174 is rotated to the right as in the state shown in FIG. While being moved to the position, the thread between the outlet nozzle 62 is cut into a brush tip shape on the downstream side of the grasping point by the thread gripping lever 174, and as a result, the thread of the small bobbin being spun is cut into the thread guide groove 173. A brush tip-like Shinohata that will be polymerized will be positioned. In this state, the Shinotsugu head 60 is shown as a solid line 15 in FIG.
Along the locus shown in 4, the small bobbin being spun is brought close to the Shino R, and the first Shino joint head is moved by the horizontal movement mechanism 61.
The 1/2 spindle pitch is laterally moved Nα33 to the right or left in the figure, so that 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,
The edge of the full bobbin is superposed on the edge R of the small bobbin. Next, as shown in FIG. 14 CB), the Shino gripping lever 17
4 is rotated to the left and moved to the neutral position, whereby the sag end of the full bobbin is guided to the sash R of the small bobbin and introduced into the trumpet 6 in a superposed 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. 14(A), and the gripping lever 1.
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 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 spun by the gripping lever 17.
4 and the nip piece 177 on the left side, it is pulled and cut to complete the shinonitsu. Thereafter, the Shino gripping lever 174 rotates to the neutral position, and Shino R's grip on Nα34 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, and the Shino joint head 60 is shown in the virtual line in FIG. In the state where the wire is located at the wire connection position shown in , the wire of the full bobbin being supplied to the trumpet 6 is grasped by the wire gripping part 175 of the wire gripping lever 174 and the nip piece 176, and the wire is cut, and the wire is supplied to the trumpet 6. It is supposed to stop.

FIG. 16 shows another embodiment of the Shinotsugi head 60.

As can be easily seen from the side view shown in FIG. 16(B), this Shino joint head 60 has two Shino gripping levers: a lever 174a for full bobbin and a lever 174b for Shino R during spinning from a small bobbin. This differs from the Shinotsugu head 60 shown in FIG. 15 in that it is used.

This Shino joint head 60 cuts the Shino R upstream from the planned polymerization section, and also cuts the Shino joint head 60 shown in FIGS. 14 and 15.
It operates in the same manner as in the case of 0, and the shin end of the full bobbin is superimposed on the shin R of the small bobbin, thereby completing the shin joint Nα35. This shinobi joint head 60 also serves as a shinobi supply stop device 305, and is designed to cut a full bobbin of shinobi by sandwiching it between a lever 174a and a nip piece 176.

Next, the inner link 146.1 of the above-mentioned Shinotsugu head operating mechanism
46, both ends of a support bar 306 are fixed to the middle part of the support bar 306, and a thread is attached to the support bar 306 at a position corresponding to each of the thread joint heads 60 so as to be able to detect thread cutting at each of the thread joint weights. A disconnection 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, and the yarn splicing head 60 Thread cutting at the corresponding Shino Tsugi weight in the state where it is located at the Tsugi position (
For example, when it is detected that there is no yarn between the drafting section 5 and the yarn guide 308, the electromagnetic valve 302 of the Shino supply stop device 305 corresponding to the thread cutting generation weight is switched as shown in FIG. 14(C). A gripping lever 174 and a nip piece 176 are electrically connected to grip a full bobbin.

The thread breakage detection device 307 may be attached to a support mechanism provided separately from the Shino joint head operating mechanism, or may be attached to the Shino exchanger 50.
It may be fixedly attached to the main body 51 of.

Next, with reference to FIG. 9, Shinokake will explain the plate operating mechanism. The plate operating mechanism of this Shinokake is also provided symmetrically on the left and right sides. The Shinokake plate 58 is a plate for hanging the fully loaded bobbin Shino on the roving guide 2. To do so, the Shinokake plate 58 must be moved along the trajectory shown by the curve 116 in FIG. In the Shino exchanger 50 shown in FIG. 1, the Shino hook 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 1
04 is pivotally connected to the main body 51 via a pin 109, &
37 The shinokake rotates clockwise about the pin 109 due to the downward movement of the plate operating rod 95, and this movement causes the sector gear 105 to rotate counterclockwise. 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 link 101 is fixed to this shaft 112. ing. The lower end of the outer link 101 has a pin 114 implanted in the connecting link 107.
a and a pin 115a implanted at the rear end of the support bar 108 so as to be rotatable. A shaft 117 is rotatably and axially movably supported on the support 1°3, and the connecting link 1
06 is rotatably connected to the shaft 117 at one end and to the shaft 112 at the other end, so that movement in the axial direction of the shaft 112 is 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 on a pin 114a implanted in the connecting link 107, and the small gears 114 and 115 mesh with each other by &38. A plate 58 is suspended and fixed to the tips of the supporting levers 108 on both sides (see Fig. 1).Although not shown, it is used when guiding a full bobbin shin after shin splicing to the roving guide 2. In order to regulate the position of the shank in the lateral direction, six V-shaped guide notches are formed on the tip side of the shank plate (on the right side in FIG. 9). 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 pin 1
14a- as a fulcrum, the tip of the plate 58 moves as shown in the trajectory 116 in FIG. In the roving guide 2, the plate 58 of the Shinogake is inclined on the machine side so as to guide the full bobbin into the roving guide 2.

Next, Shinokake explains the mechanism for moving the plate 58 laterally. The shinokake plate 58 is moved by, for example, 20 mm in order to hang the shin of the full bobbin 1a on the claw part 2b of the roving guide 2 shown in FIG. moved by The plate lateral movement mechanism 59 has a motor 117 with a reducer fixed to the main body 51, a worm 118 rotated by the motor 117 via a gear 117a, and a worm wheel that meshes with the worm 118 at one end. The shaft 11 of the plate actuating mechanism selectively swings to the right or left in FIG. 1 about the pin 119a.
It consists of an arm 119 that moves the 2 laterally. As shown in FIG. 9, by the lateral movement of the shaft 112, the inner link 102 is simultaneously moved laterally via the outer link 101 and the connecting link 106, and the plate 58 of the Shinokake holding the full bobbin is also moved laterally. Ru. The lateral movement of the plate 58 is carried out with the plate 58 raised to guide the roving into the roving guide 2, and as a result, the claw 2b of the roving guide 2 is engraved with the shin.

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 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 exchanging full bobbins and small bobbins. At the same time, the thread of the full bobbin is joined to the thread of the small bobbin that is being spun, and when a thread cut occurs during the thread joining, the thread of the full bobbin at the thread cutting generation weight is cut above the trumpet 6. do. Since the configuration and operation of the controller are well known, detailed explanation will be omitted.

Next, a case 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 will be described. First, Nα41 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 the small bobbin 1c, and the bobbin suspended from the rear row bobbin hanger 20 becomes the middle bobbin. When the ball bobbin 1b is obtained, the guide roller 29 of the Shino exchanger 50 is placed on the guide rail 28 of the spinning machine,
The Shino switching machine 50 is connected to a spinning machine. For this special transport, a full bobbin 1a is suspended in advance from a spare bobbin hanger 24 arranged on a spare rail 15 of the spinning machine so as to face 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 5o travels along the front surface of the spinning machine by driving a scroll cam 22 with a 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.

N (142 First of all, the small bobbin 1c in the front row has less shine remaining and is in a state where it needs to be replaced (Fig. 17 (1))
. When this state is reached, as shown in FIG. 17 (2), the full bobbin exchange head 52 corresponding to the position directly below the full bobbin 1a hanging 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. The full bobbin exchange head 52 carrying the full bobbin 1a 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 position of the thin end of the full bobbin 1a which has been raised and lowered (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 unwinding 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 outlet nozzle 62 enters the liner guide groove 173 of the liner joint head 6o (Fig. 17). (5))
. In this case, the electromagnetic valve 302 for operating the Shinotsugu head 6o.
304 i:li, in the state shown in FIG. 14(B), and after Shino enters the Shino guide groove 173 as described above, the electromagnetic valves 302 and 304 are operated to the state shown in FIG. 14(C). Rotate the Shino gripping lever 174, and the Shino gripping lever 17
The full bobbin Shino is gripped between the Shino gripping part 175 and the nip piece 176 of No. 4, and at the same time, the Shino joint head 60, which was in a downward vertical position, is brought to a sideways, almost horizontal state by the Shino joint head operating mechanism, and at that time, the full bobbin Shino in 1a is outlet nozzle 62
It is caught by a comb attached to the inside of the tip of the blade, and is cut between the gripping point on the head 60 and the outlet nozzle 62 to form a head (FIG. 17(6)). Next, the Shino joint head 6 is held while holding the full bobbin Shino on which the Shino edge has been formed.
1 is advanced toward the drafting section 5 of the spinning frame by the Shinotsugi head operating mechanism. The Shino-tsugi head 60 temporarily stops moving forward while moving forward, and is moved by the Shino-tsugi head lateral movement mechanism 61 to the trumpet 6 side (to the right in FIG. 4) where the Shino of the JM ball bobbin is not being introduced. The spinning machine moves laterally by two spindle pitches to take the longitudinal position of the spinning machine corresponding to the trumpet 6 upstream of the drafting section 5 of the spinning machine, and then resumes forward movement so that the end of the full bobbin is at the position of the trumpet 6. Continue until you reach the top. At this time, it enters the thread guide groove 173 of the thread joint head 60 of the small bobbin being spun, and overlaps the thread 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 preventing the Shino from being cut due to the advance of the Shino joint head 6Nα450. At the same time, in order to hold the slack of the unwound shin, the shinokake plate 58 is slightly raised by the shinokake plate operating mechanism.

After the Shinotsugi head 60 stops moving forward, the electromagnetic valves 302 and 304 for operating the Shinotsugi head 60 are switched as shown in FIG. The grip of the bobbin's grain is released, and the grain of the released full bobbin 1a is guided by the grain of the small bobbin being spun and inserted into the trumpet 6 together with the grain, and the grain end of the full bobbin 1a is brought into the drafting section 5. After being gripped by the back roller 5a, the electromagnetic valve 304 for operating the Shinotsugu head 60
As shown in FIG. 4(A), the gripping lever 174 further rotates to grip the grain of the small bobbin between the grain gripping portion 175 and the nip piece 177. Kodama□
Since the thread of the bobbin is held by the thread joint 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 Nα46 girder 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 thread, thereby preventing the thread from being cut due to the rise of the full bobbin 1a. Furthermore, it rises to the vicinity of the roving guide 2 and holds the slack of the fully unwound bobbin 1a. During this time, the electromagnetic valve 304 for operating the Shino joint head 60 is switched again as shown in FIG. 14(B) to move the Shino grip lever 174 to the neutral position.
This moves the Shino grip lever 174 to the neutral position,
As a result, the grip of the small bobbin by the grip lever 174 is released. On the other hand, as described above, the Shinotsugu head 60
is moved to the splicing position shown in FIG. 17 (7), each thread breakage detection device 307 is positioned so as to face the thread path between the drafting section 6 of the corresponding thread splicing weight and the thread guide 308. , and then, at the time when the thread joining operation is performed as described above, the thread cutting detection device 307
is in a state where it is possible to determine whether or not there is a thread cut at each thread joint weight. If a thread break occurs at least before the thread joint part is wound around the bobbin of the spindle Nα47, the thread detection device 307 detects the thread cut, and based on the detection signal, the thread cut corresponds to the spindle spindle Nα47. Supply stop device 3
The electromagnetic valve 302 of 05 (Shinotsugi head 60) is switched and operated as shown in FIG. 14(C). As a result, compressed air is supplied to the piston chamber 186b on the right side of the air cylinder 186, and the Shino gripping lever 174 is rotated from the neutral position shown in FIG. 14(B) to the full bobbin Shino gripping position shown in FIG. 14(C). , the full bobbin that is being supplied to the trumpet 6 is gripped between the shinobi gripping portion 175 of the shinobi gripping lever 174 and the nip piece 176.

After that, the thread connecting head 60 moves back to a position where the thread of the fully loaded bobbin where no thread breakage occurs and comes off the thread guide groove 173 and stops (FIG. 17(8)), and the thread connecting head 60 retreats. As a result, the full bobbin 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. In addition,
If there is a long time between the retreat of the thread joint head 60 and the gripping of the full bobbin by the thread gripping lever 174, the full bobbin thread is cut by being drawn into the trumpet 6 before the thread joint head 60 moves back. Therefore, even if the supply of the full bobbin wire to the trumpet 6 at the thread-trimming weight is stopped and the thread-cutting state of the weight is left for a long time, there is no risk of the wire winding around the roller. After that, the Shino supply stop device 3
The electromagnetic valve 302 of No. 05 is switched again as shown in FIG. 14(B), and as a result, the Shino gripping lever 174 is rotated to the neutral position to release the full bobbin Shino grip.

Next, the small bobbin exchange head 55 advances and rises to just below the small bobbin in the front row of the creel using 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 on which the small bobbin is placed moves downward (Fig. 17 (10)).
, retreat and return to the original position. (Figure 17 (11)). The small bobbin is rotated clockwise when viewed from the top by the begging rotation mechanism built in the small bobbin exchange head 55, and the cut wire is wound up. Small bobbin exchange head 55
At the same time, the full bobbin exchange head 52 descends and returns to its original position. At this time, the full bobbin 1a is rotated clockwise by an appropriate amount by the peg rotation mechanism of the full bobbin exchange head 52 to wind up the wire, and the slack of the wire caused by the lowering of the full bobbin exchange head 52 is properly maintained. The plate 58 of the Shinogake is moved horizontally by the plate lateral movement mechanism 59, and the Shinogake of the full bobbin 1a is passed through the roving guide 2 installed in the spinning machine and returned to its original position. Shinotsugu head 60 on the way back
stops retracting, 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)). The shinotsugi head 60 that has finished retreating is returned from the approximately horizontal state to the vertical state (FIG. 17 (13)). The full bobbin exchange head 52 moves forward to just below the bobbin hanger 19 in the front row, rises, and transfers the full bobbin 1a to the bobbin hanger 19.
Attach. 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 properly maintain the slack of the wire caused by the advance of the full bobbin exchange head 52 and the rise in Nα50. Thereafter, the movable small bobbin exchange head 55 moves forward 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 (see Figure 17 (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)).

Thus, the Shino exchange work of the cycle is completed, and the Shino exchange machine 5
0 moves 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 exchange machine 5o may perform the Shino exchange and Shino joint work according to the following procedure. Raise the full bobbin exchange head 52 and remove the full bobbin 1.
After fitting the small bobbin a into the peg 53 (Fig. 17 (2)), move the small bobbin exchange head 55 forward and raise it to remove the small bobbin 1c.
Remove it from the front row bobbin hanger and return it to its original position. The full bobbin 1a and the small bobbin 1c are in the positional relationship shown in FIG. 17 (11), and the small bobbin Nα51 and the grain of the bin 1c are spun. Next, the full bobbin exchange head 52 is lowered, and the thread end from the full bobbin 1a is gripped by the thread joining head 60 and guided above the trumpet to perform thread joining in the same manner as described above. After the thread splicing is completed, the full bobbin 1a is hung on the front row bobbin hanger 19, and the small bobbin 1c is suspended from the spare bobbin hanger 24 of the spare 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 peg 56 of the small bobbin exchange head 55 and the shin joint is performed, the shino being spun from the small bobbin 1c to the roving guide 2 is connected to the small bobbin. Rotate the small bobbin 1c 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 1c at a speed equivalent to the amount of spinning of the shin until the shin splicing work is completed. It is necessary to continue the unwinding rotation of 1c. However, according to this method, the first
In the embodiment shown in FIG. 7, when replacing the full bobbin 1a and the small bobbin 1c after the completion of the connection, the full bobbin 1a is retracted upward to avoid interference with the rain bobbin (FIG. 17 (9) to (9)
11) Operation of full bobbin 1a) can be omitted.

In this embodiment, since the Shinotsugi head 60 is provided to correspond to the center of the full bobbin 1a, the Shinotsugi head 60 is moved laterally by 172 spindle pitches during the forward movement so that it corresponds to the trumpet 6. There is, but this one
The lateral movement of /2 spindle pitch is performed on the same spinning machine, first moving to the left side, and then moving to the right side at the time of the next frame change. In other words, the small bobbin I is alternately moved horizontally to the left and horizontally to the right.
Needless to say, the Shinotsugu head 60 is guided above the trumpet 6 on the side where C is spinning.

If the Shino-tsugi head 60 and the outlet nozzle 62 are designed to be able to move laterally by the spindle pitch, and the end of the full bobbin 1a is brought out at a position corresponding to the trumpet 6, the lateral movement of the Shino-tsugi head 60 during forward movement can be avoided. This eliminates the need to perform these 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 62 are connected.
Trumpet 6Nα5 spun by small bobbin 1c
It will be moved to the position corresponding to 3 in advance.

In addition, when the outlet nozzle 62 is set at a position corresponding to the trumpet 6, and the Shinotsugu head 60 is positioned so as to be able to move laterally by the spindle pitch, the lateral movement of the Shinotsugu head 60 during the forward movement is caused by 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, a 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 changer 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 sufficient to pull out the thread end of the full bobbin 1a and perform the thread joint, and after the thread joining is completed, remove the small bobbin 1c and replace the thread. As a result, the Gokuraku Nα54 exchanger 50 is large. Further, in the above embodiment, after the thread splicing, the thread of the small bobbin during spinning is cut using the thread gripping lever 174.
is gripped by the nip piece 177, and pulled and cut by the spinning of the back roller 5a.
It would not depart from the present invention even if the upper surfaces were configured to rub against each other, and the lower surface of the shingle gripping lever 174 and the upper surface of the nip piece 176 were used to cut the shingles like scissors.

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 actuating bar 182 and moving it in parallel. In addition, a plurality of Shinotsugu heads 60
When the Shino grip levers 174 are operated by the same actuating bar 182, a spring may be interposed between the Shino grip lever 174 and the actuation bar 182 so that the Shino grip in each Shino joint 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 cut detection device detects thread cut during Shino joint, each Shino supply stop device Nα55 is activated by a trumpet. After moving forward upward, 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 cut. It is also possible to release the grip on the bobbin. Further, each thread supply stop device may be configured to move back and forth independently, and only the thread supply stop device corresponding to the thread trimming weight may be moved 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 suction-held and cut by suction airflow. 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. Take out the front and rear two small bobbins in advance to the spare bobbin hanger, and then insert the two full bobbins inserted into the spare bobbin hanger into the front and rear row bobbin hangers after taking them out. It may also be carried out on the Shino exchange that was made.

Effects of the Invention As described above, in the present invention, the thread exchanger is equipped with a thread connection device, and the thread end of the full bobbin is connected to the thread of the small bobbin at the time of thread exchange. It is possible to automatically perform the shino-joining work during the process, resulting in significant labor savings. In addition, the Shino exchange machine is equipped with a thread break detection device and a Shino supply stop device, so that when a thread break occurs at the Gokuraku change weight, the supply of Shino to the trumpet at the thread break occurrence weight is stopped. Even if thread breakage occurs due to some reason during thread splicing, it is possible to reliably prevent the weight from wrapping around the roller at the weight where the thread breakage occurred.
It is possible to unmanned the work of replacing the shins and to eliminate waste of shins.
