First, the full bobbin replacement head 52 will be described. On the change bar 71 of the full bobbin exchange head 52, six full bobbin exchange head pegs 53 are rotatably arranged (FIG. 11). In order to use the peg 53 to move the full bobbin 1a at the position shown in FIG. 3 to the position of the small bobbin 1c, it is necessary to move the peg 53 up and down and back and forth. As shown in FIG. 5, the change bar 71 on which the six pegs 53 are arranged is the inner link 7
5 and the outer link 76 are disposed above the elevating body 37 of the full bobbin exchange head elevating mechanism 31 shown in FIG. Two chains 36a, 36b parallel to each other in the vertical direction are connected to the lifting body 37. The chains 36a, 36b are connected to the motor 32 for the full bobbin replacement head lifting mechanism arranged in the Shino exchange 50. The lifting / lowering body 37 is moved up and down by moving it up and down. That is, the 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 by the main body 51 of the Shino exchange 50 through the chain 33b and the chain wheel 34a. It Chain wheels 35a, 35 are provided at both ends of the shaft 34.
The chain 36a, 36b mounted on the chain wheel 35a, 35b has one end directly connected to the lower part of the elevating body 37 and the other is rotatably arranged above the main body 51. It is connected above the lifting body 37 via the chain wheels 39a, 39b, and therefore the shaft 34
The vertical movement of the lifting / lowering body 37 is achieved by the rotation of. At that time, the lifting body 37 is provided with a guide member 38 provided vertically to the main body 51.
Since it is slidably fitted to the a and 38b, accurate movement in the vertical direction is secured. Next, full bobbin replacement head 52
The back-and-forth movement is performed by the full bobbin changing head back-and-forth movement mechanism shown in FIG. A housing 77 is provided above the lifting / lowering body 37. The rotation of the motor 86 in the housing 77 causes the arm 82 to swing through the speed reducer 85 and the gears 84 and 83, and the swing motion is provided at the tip of the arm 82. It is transmitted to the swing arm 80 via the sliding pin 81 and the elongated hole 80a of the swing arm 80 with which the slide pin 81 is engaged. A lower end of the outer link 76 and a swing arm 80 are fixed to a pin 79 pivotally attached to the housing 77. As a result, the reciprocating rotational movement of the drive gear 84 in the arrow direction causes the swing arm 80 and the outer link 76 to swing in the arrow direction. 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 the change bar 71 is fixed to the other end of the support member 72. On the other hand, a pivot pin 73 is provided at an intermediate portion of the change bar support member 72, and the upper end of the inner link 75 is connected via the pivot pin 73. The lower end of the inner link 75 is connected to the housing 77 via a pivot pin 78. Therefore, the change bar 71 is moved by the swinging movement of the outer link 76 in the arrow direction.
The upper peg 53 can be moved back and forth with respect to the spinning machine in a state where the upper peg 53 is maintained in the vertical direction, and can be moved to a position directly below the preliminary bobbin hanger 24 and a position directly below the front row bobbin hanger 19.

Next, the full bobbin peg 53 and its rotating mechanism in the full bobbin exchange head 52 will be described with reference to FIGS. 10 to 13. 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, 53) at intervals of 2 spindle pitches.
d, 53e, 53f) are provided. These pegs 53 are designed to be rotated to rewind or wind the Shino from the full bobbin in various steps of Shino exchange, as will be described later in detail regarding the operation of Shino exchange. Further, as shown in FIG. 10, these pegs 53 can be rotated 180 ° separately from the other pegs 53 at the beginning of the shino exchange operation, as shown in FIG. The reason for this is that, as described below, the full bobbin in this embodiment is properly exposed at the shin end. In other words, since the flyer presser position of the full bobbin wound on the roving frame is 180 ° different between the front row and the rear row in the roving machine, the front row is different from the back row.
It is located 180 ° on the opposite side. Therefore, if every full bobbin of the front and rear rows doffed by the roving machine is put in every other space and rearranged in a row, and the full bobbins are hung on the spare rail 15 using the bobbin carriage 17 in a row, As shown in FIG. 10 (A), the Shino ends 1ae of Shino 1a of these full bobbins are positioned on the opposite side every other 180 °. That is, in FIG. 10 (A), when the shino edge 1ae of the full bobbin at the positions (a), (c) and (e) is at the position facing the outlet nozzle 62, (b), ( The shin edge 1ae of the full bobbin at the positions d) and (f) is on the opposite side of the dispensing nozzle 62. When the six full bobbins are simultaneously returned and rotated in order to be ejected by the ejection nozzle 62 in this state, since the mutual intervals between the full bobbins are generally small, the Shino end located on the opposite side of the ejection nozzle 62 is the ejection nozzle. By the time it reaches 62, its Shino end may adhere to the peripheral surface of the adjacent full bobbin and be wound around the full bobbin, and it may become impossible to take out. Therefore, the full bobbin 1 at the positions (b), (d), and (f) at the beginning of the operation of the Shino exchange.
Rotate a in the winding direction by 180 ° in advance and see Fig. 10 (B).
As shown in FIG. 6, the Shino ends 1ae of the six full bobbins are aligned so as to face the outlet nozzle 62, and then the six full bobbins are rotated in the rewinding direction. When the distance between the full bobbins is large, it is sufficient to rotate the bobbins in the rewinding direction from the beginning without rotating them in the winding direction in advance. As described above, in order to rotate the six pegs 53 every other one, as shown in FIGS. 11 and 12, each peg 53 is rotatably supported by the change bar 71, and the pegs 53 are rotatably supported.

And swings clockwise through the pivot 145 against the tensile force of the spring 153, and the pin 151 at the upper end of the outer link 147
Push to the right and turn connecting link 150 counterclockwise around pin 149. As a result, the Shinotsu head support bar 148 rotates counterclockwise with the Shinotsu head 60. This pivoting motion continues from the position shown in FIG. 8 of the connecting link 150 to a position opposite the symmetrical line with respect to the vertical line passing through the pin 149, with the result that the connecting head 60 is in a substantially horizontal position. Furthermore, the rod 97 for operating the Shinotsu head moves downward to move the outer link.
When 147 is rotated further clockwise, the pin 151 becomes the long hole 150a.
The pin 149 is pulled to the right by the connecting link 150 to rotate the inner link 146 about the shaft 145, and the horizontally oriented Shinojo head 60 is indicated by 154. It follows that it follows the traced path toward Shino R from the small bobbin 1c being spun.

The position of the full bobbin on the spinning machine and the position of the drafting unit 5 are usually displaced by 1/2 pitch of the spindle of the spinning machine, as shown in FIG. Therefore, when the Shinobashi of the full bobbin is squeezed out, and when the Shinobu head 60 is gripped by the Shinobu head 60 and moved to the drafting unit 5, the drafting unit in which the Shinobu bobbin Shino to which the Shinobu head 60 is to be introduced is introduced. It is necessary to move laterally by 1/2 spindle pitch to the 5 side. Therefore, as shown in FIG. 1, a transverse joint head lateral movement mechanism 61 is provided to move the pivot shaft 145. Shinotsuji head lateral movement mechanism 61
Has a reduction gear motor 217 fixed to the main body 51, a worm 218 rotated by the motor 217, and a worm wheel meshing with the worm 218.
The arm 155 swings around the center of the arm 155, and the swinging of the arm 155 selectively moves the rod 145 to the right or left in FIG.

Next, the structure and operating method of the Shinobu head 60 will be described with reference to FIGS. 14 to 17. FIG. 14 shows a plan view of an embodiment of the Shinotsu head, and FIG. 15 shows a side view thereof. The Shinotsu head 60 shown in FIGS. 14 and 15 has a Shino guide head body 173 having a Shino guide groove 173 formed at the tip thereof.
71 and a shining grip lever 174 that can reciprocate across the shining guide groove 173 in a plane parallel to the upper surface of the body 171. The main body 171 is fixed to a Shino joint head support bar 148 having a U-shaped cross section. Shino grip lever 174 is the main body 171
A pivot pin 178 fixed to the shaft is rotatably supported near its center, while a pin 179 is projectingly provided at the rear end thereof. As shown in FIG. 15, the Shino joint head support bar 148 is slidably provided with a Shino gripping lever operation bar 182, and the operation bar 182 has an operation member having an opening portion for accommodating the pin 179 at the tip thereof. 181 is fixed. Shino grasping lever 1
The tip of 74 is the Shino gripping part 175 on both sides of Shino gripping surfaces 175a, 175b
The nip pieces 176 and 177 having shino gripping surfaces 176a and 177a opposed to the main body 1 are provided at positions on both sides of the shino guide groove 173, respectively.
It is fixedly arranged on the upper surface of 71. A triangular shino guide opening 172 for guiding the shino into the shino guide groove 173 is formed at the tip of the main body 171, and air sent via the conduit 184 is guided to one side of the shino guide opening 172. An opening of a nozzle 183 that jets downward in the inner part of the groove 173 is provided.

The airflow ejected from the nozzle 183 serves to extend the bending of the shining end of the full bobbin which is superposed on the shining end of the small bobbin 1c being spun. FIG. 14 (A) shows a case in which the operating bar 182 moves to the right and grips a small bobbin Shino (not shown) between the Shino gripping surface 175a of the Shino gripping lever 174 and the Shino gripping surface 177a of the nip piece 177. And full bobbin Shino Shino guide groove 173
7 shows the position of the shino gripping lever 174 in the standby state for guiding to.
The full bobbin 1c in the state in which the Shinotsuji head 60 is positioned at the vertical position of the Shinotsuji head 60 described with reference to FIG.
The Shino that extends between the discharge nozzle 62 and the discharge nozzle 62 is introduced into the Shino guide groove 173 through the Shino-inlet opening 172, and the Shino gripping lever 174 moves the Shino grip 175 to the right as in the state of FIG. 14 (C). While being rotated and gripped by the Shino gripping lever 174 and the nip piece 176, and then the Shino joint head 60 is moved from the vertical position to the horizontal position, the Shino grip between the outlet nozzle 62 and the Shino gripping lever 174 is At the downstream side, it is cut like a writing brush, and as a result, a writing brush-shaped shining end to be overlapped with the shining of the small bobbin being spun is located in the shining guide groove 173. By repeating the movement from the vertical position to the horizontal position, the monofilament entangled at the tip of the shin is removed, and the shape becomes uniform like a writing brush. In this state, the Shinetsutsu head 60 is the 8th
Along with the locus shown by the solid line 154 in the figure, it is brought close to the small bobbin Shino R that is being spun and is horizontally moved to the right or left in FIG. Shino R of the small bobbin being spun in 6 is introduced into the Shino guide groove 173, and the Shino end of the full bobbin is superposed on Shino R of the small bobbin. Next, as shown in FIG. 14 (B), the shining lever
The Shino grip 175 of 174 is rotated to the left and moved to the neutral position, whereby the Shino end of the full bobbin is guided to Shino R of the small bobbin and introduced into the trumpet 6 in a superposed state.
After that, when the Shino end of the full bobbin is introduced into the back roller 5a of the drafting unit 5, as shown in FIG. 14 (A), the Shino gripping unit 175 is fully rotated to the left side and the Shino gripping lever 174 is rotated.
Shino R of the small bobbin is gripped between the left grip surface 175a of the shin grip 175 and the grip surface 177a of the left nip piece 177. In this way, since the downstream shino of the shin joint head 60 is spun toward the drafting section 5, the part joined to the shin joint advances to the downstream side, and the shino R upstream of the joined part is the shino gripping lever 174 and the left nip piece. Since it is gripped at 177, it is pulled and cut, and the piecing is completed. After that, the Shino gripping lever 174 rotates to the neutral position, and the grip of Shino R is released.

Next, with reference to FIG. 17, the sliding movement of the operating bar 182 for operating the turning movement of the grasping lever 174 will be described. As shown in FIG. 17, the operating members 181 of the six Shino connecting heads 60 are fixed to the operating bar 182 housed in the Shino connecting head supporting bar 148. On the actuating bar 182, there are four plungers 189 of solenoids 185 for sliding the actuating bar, which are fixed to the Shinodai head support bar 148, L-shaped member 188 and pin.
200 and hole 186, respectively. When each solenoid 185 is not energized, the plunger 189 is free to move, and when energized, the plunger 189 is retracted. The pin 200 engages with the operating bar 182 through the hole 186 to transmit the movement of the plunger to the operating bar 182. Hole 186 with which the pin 200 engages
Has a hole 186a, 186d corresponding to the solenoid 185a, 185d
Is a long hole that is long in the moving direction of the operating bar 182.
The holes 186b and 186c corresponding to 185b and 185c are formed as long holes that are long in the direction orthogonal to the moving direction of the operating bar 182. As shown in FIG. 17 (A), the solenoid 185c is energized (O
N) Then, the retracted and pin 200c to the plunger 189 is solenoid 185c to move to the right to indicate the operating bar 182 to move as indicated by the arrow C to the right by the arrow X _1, the resulting Shino gripping lever 174 The tip 175 rotates to the left and comes into contact with the nip piece 176 to grip the full bobbin (see FIG. 14C). Next, set the Shino grip lever 174 to the first
To obtain the neutral position shown in FIG.
Energize (ON) solenoid 185d as shown in FIG.
Then, by moving the pin 200d in the direction of arrow D,
Move the operating bar 182 in the direction of arrow X2. At the same time, the solenoid 185a is energized, and the solenoid 185a plunger
Since the 189 is kept in the retracted position, the actuating bar 182 is positioned at the neutral position with the right side of the elongated hole 186a abutting the pin 200a.

Further, in order to move the shino grasping lever 174 to the position for grasping the shino of the spinning small bobbin shown in FIG. 14 (A), the solenoid 185b is energized as shown in FIG. 17 (C). ON), and by retracting the plunger 189, the pin 200b is moved in the direction of arrow B, and the operating bar 182 is moved to arrow X.

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

FIG. 16 shows another embodiment of the Shinotsu head 60. In this Shinobu head 60, a full bobbin Shino lever is used as a Shino gripping lever, as can be easily seen from the side view shown in FIG. 16 (B).
2 of 174a and lever 174b for Shino R spinning from small ball bobbin
The fact that a book is used is different from the Shinotsu head 60 shown in FIG. Therefore, correspondingly to the operating bar, the operating bar 182a for full bobbin Shino and the operating bar 182b for Shino R are used, and the Shino R is cut upstream from the polymerization planned portion, and also, as shown in FIGS. By operating in the same manner as in the case of the Shinotsu head 60, the Shino end of the full bobbin is superposed on Shino R of the small bobbin to complete Shino Kozo.

Next, the shining plate actuating mechanism will be described with reference to FIG. This Shino hanging plate actuating mechanism is also provided symmetrically on the left and right. The Shino hanging plate 58 is a plate for hanging the Shinbo of the full bobbin that has finished Shining on the roving guide 2. For that purpose, the Shino hanging plate 58 must be moved along the locus shown by the curve 116 in FIG. I have to. In the Shino exchange 50 shown in FIG. 1, the Shino hanging plate 58 is formed as one plate extending in the longitudinal direction of the Shino exchange 50. The shining plate operating mechanism is the shining operating cam 68 of the operating mechanism 65 shown in FIG.
The downward movement of the rod 95 for operating the shining plate is caused by the movement of the link mechanism that combines the outer link 101 and the inner link 102 to give the shining plate 58 a desired movement locus. That is, the sector gear 104 is pivotally attached to the main body 51 via the pin 109, and is rotated clockwise about the pin 109 by the downward movement of the rod 95 for operating the hanging plate, and the movement is performed by the sector gear 1.
Brings 05 counterclockwise rotation. This sector gear 1
Reference numeral 05 is fixed to a shaft 112 rotatably and slidably supported in a longitudinal direction by a support 103 attached to the main body 51, and the upper end of the outer link 101 is fixed to the shaft 112. . The lower end of the outer link 101 is rotatably attached to a pin 114a planted in the connecting link 107 and a pin 115a planted in the rear end of the support lever 108. A shaft 117 is rotatably and axially movably supported by the support 103, and one end of the connecting link 106 is rotatably attached to the shaft 117 and the other end is rotatably attached to the shaft 112. Is transmitted to the shaft 117. And the inner link 102 to this axis 117
The upper end of the inner link 102 is fixed, and the lower end of the inner link 102 is connected to the connecting link 107 by the pin 113. Connecting link 107
The pinion 114a planted in the
The pin 115a planted in 108 is wedged to the spur gear 115,
114 and 115 are in mesh. A plate-shaped shining plate 58 is suspended and fixed to the tips of the support levers 108 on both sides (see FIG. 1). Although not shown in the drawing, when guiding the shining of the full bobbin to the roving guide 2, Six V-shaped guide notches are formed on the front end side (right side in FIG. 9) of the Shino hanging plate in order to regulate the horizontal position of the Shino. With this configuration, the outer link 101 and the inner link 102 both rotate counterclockwise as the sector gear 105 rotates counterclockwise, and when the outer link 101 and the outer link 101 approach the swinging end of the outer link 101, the outer link 101 and the outer link 101 rotate. 102, link 1
Due to the connection length of 07, the connecting link 107 is rotated counterclockwise with the pin 114a as a fulcrum, and the small gear 115 meshing with the small gear 114 is rotated clockwise accordingly, so that the hook plate The tip of 58 moves like a locus 116 in FIG. 9, and when it reaches the swinging end of the outer link 101, the shining plate 58 is tilted toward the machine base above the roving guide 2 to move the full bobbin It is designed to be guided into the roving guide 2.

Next, a mechanism for laterally moving the Shino hanging plate 58 will be described. The Shino hanging plate 58 is moved by the Shino hanging plate lateral movement mechanism 59 shown in FIG. 1 in order to move, for example, 20 mm in order to hook the full bobbin 1a on the claw portion 2b of the roving guide 2 shown in FIG. To be made. The horizontal hanging plate lateral movement mechanism 59 has a motor 117 with a speed reducer fixed to the main body 51, a worm 118 rotated by the motor 117 via a gear 117a, and a worm wheel meshing with the worm 118 at one end. , An arm for selectively swinging the pin 119a to the right or left in FIG.
Composed of 19. As shown in FIG. 9, the lateral movement of the shaft 112 causes the lateral movement of the inner link 102 via the outer link 101 and the connecting link 106 at the same time, whereby the shining plate 58 holding the full bobbin is also moved laterally. . The lateral movement of the Shino hanging plate 58 is performed with the Shino hanging plate 58 being lifted and guiding the Shino into the roving guide 2. As a result, the claw portion 2b of the roving guide 2 is bent.

Next, with reference to FIG. 19 to FIG. 21, a remaining bobbin winding device for the small bobbin will be described. As will be described in detail later in the description of the operation of the Shino exchange 50, the remaining Shinobu bobbin cut after being Shino-Jointed by the Shino-Joint head 60 is the Kodama bobbin 1.
It is hanging from c. The small ball bobbin 1c after winding down the hanging remnants is transferred to the spare bobbin hanger 24 on the spare rail 15, and then the small ball bobbin 1c is normally hung to carry out the next round winding work from the spare rail 15. Is moved to the Zanshino processing process. At that time, if you do not wind the remaining Shinoshino around the small ball bobbin 1c, the remaining Shinoshino will hang down from the small ball bobbin 1c again during the movement, and sometimes the weight of the hanging residual Shinoshino itself will cause all of the small Shinobu on the small ball bobbin 1c to become small balls. An unfavorable phenomenon such as falling off from the bobbin 1c, dropping onto a passage or a spinning machine in operation, and being entangled with a yarn or the like being spun occurs. In order to avoid such a phenomenon that the remnants hang down from the small ball bobbin 1c again, in this embodiment, after mounting the small ball bobbin on the rotatable peg 56 of the small ball bobbin exchange head 55, the small plate bobbin is lifted by the lifting plate 204. Scoop up the part of Shino that hangs down to the side of the small bobbin and stroke the outer circumference of the small bobbin against the touching plate 211.In this state, rotate the small bobbin in the winding direction and hang it down. Is surely wound around the small bobbin.

FIG. 19 shows an arrangement state of the lifting plate 204 and the stroke plate 211 with respect to the mechanism for moving the small bobbin changing head forward and backward. Small ball bobbin replacement head back and forth movement mechanism is the fifth
The bobbin has three small bobbin pegs 56, which are configured in the same manner as the full bobbin changing head longitudinal movement mechanism described with reference to the drawings.
The small bar bobbin change bar 70 in which the two are arranged at the intervals of two spindle pitches is the inner link 201 and the outer link 20.
2 can be used to move between the position shown by the solid line in FIG. 19 and the position shown by the chain double-dashed line where it can be engaged with the small bobbin 1C of the spinning machine. As described above, since the small ball bobbin changing head lifting mechanism is provided on both sides of the full bobbin changing head lifting mechanism 31, the small ball bobbin change bars 70 are provided corresponding to the small ball bobbin changing head lifting mechanism, respectively. Therefore, one lifting plate 204 is provided for each small bobbin change bar 70. As shown in FIGS. 19 and 20, the lifting plate 204 is formed in a plate shape extending parallel to the change bar 70, and has a notch portion 204a above which is provided to guide the remnants. Are fixed to the tips of the two support levers 203. A roller 205 is rotatably attached to a rear end of the support lever 203, and a pin 20 is attached to a support bracket 210 extending upward from the change bar 70 at an intermediate position thereof.
Mounted rotatably by 6. The mounting position of the support lever 203 on the support bracket 210 is such that when the change bar 70 is below the small bobbin 1c on the spinning machine as shown by the chain double-dashed line in the right side of FIG.
The weight of the right side portion of the mounting position of the support lever 203 rotates clockwise around the pin 206 as shown in the drawing, and the tilt position is determined by the pin 209 provided above the support bracket 210. On the other hand, a stopper 207 is fixedly arranged on the main body 51 of the Shino exchange 50 via a stopper support member 208. When the change bar 70 is moved to the position shown by the solid line on the left side of FIG. 19, the stopper 207 has the roller 205 at the rear end of the support lever 203 and the stopper 207.
The support lever 203 and the support lever 203 is rotated counterclockwise about the pin 206 to lift the lifting plate 204 from the small bobbin 1c.
Is configured to move to the side of.

On the other hand, as shown in FIGS. 19 and 21, the touching plate 211 is attached to the main body 51 of the Shino exchange 50 through the support bracket 212 so as to contact the Shino surface of the small bobbin 1c. The attachment plate 211 preferably has a flat plate shape parallel to the axis of the small bobbin 1c and is made of an elastic material such as rubber. The attachment plate 211 is provided for each small bobbin 1c, and the relative position of the small bobbin 1c with the shin surface is lifted when the small bobbin 1c reaches the rearmost position (the position on the left side in FIG. 19). Adjust the adjustment bolt 213 so that the residuum that is lifted up to the side of the small bobbin 1c by the plate 204 and wound on the small bobbin 1c by the rotation of the small bobbin 1c is wound on the surface of the Shino layer of the small bobbin 1c while being stroked. Is adjusted using. Thus, when the small ball bobbin 1c with the hanging reeds moves from the right side position to the left side position in FIG. 19 together with the change bar 70 by the small ball bobbin forward / backward moving mechanism, the lifting plate 211 rotates counterclockwise as described above. Scoop up the part of Shino that hangs near the small bobbin 1c to the side of the small bobbin 1c, and at the same time, touch the plate 21 on the outer circumference of the small bobbin 1c that rotates to wind the remaining Shinobu.
Since 1 touches, the hanging samurai is a small ball bobbin 1
It will be surely wound around c.

As described above, the Shino exchange is provided with various operating mechanisms each having a motor. As will be apparent from the explanation of the operation of the Shino exchange machine, the movement of the outlet nozzle, Shino joint head, Shino hanging plate, and full (small) bobbin exchange head is carried out in a predetermined order. Therefore, the motors in the various operating mechanisms are operated in a predetermined order based on a command from the controller 300 provided in the main body 51 of the Shino exchange 50, whereby the full bobbin and the small bobbin are exchanged. Along with being told, Shinobu of full bobbin is being spun on to Shinobu of small bobbin. Since the configuration of the controller and its operation can be easily understood by a known technique, detailed description thereof will be omitted.

Next, a description will be given of a case of performing a shino exchange in a broad sense, that is, an exchange of a full bobbin and a small bobbin, and a piecing operation using the shino exchange 50 having the above configuration. First, as shown in FIG. 3, bobbin hangers 1 in the front row are formed by spinning as the creels of the spinning machine advance.
The bobbin hung on 9 becomes the small bobbin 1c, and the bobbin hung on the bobbin hanger 20 in the rear row is the middle bobbin 1
When it becomes b, the guide roller 29 of the Shino exchange 50 is placed on the guide rail 28 of the spinning machine, and the Shino exchange 50 is brought into contact with the spinning machine. By this time, the spare rail 1 of the spinning machine is in advance.
The full bobbin 1a is placed on the spare bobbin hanger 24, which is arranged facing the position of the bobbin hanger 19 in the front row of the spinning machine.
Hang it. When the bobbin suspended on the bobbin hanger 20 in the rear row becomes a small ball and a shino exchange is required, the small bobbin is arranged in the front row in advance by using the shino entry pipe machine 10 described above. deep.

The Shino exchange 50 travels along the front surface of the spinning machine by driving the scroll cam 22 by the traveling motor 21, and stops at a position corresponding to six small bobbins 1c. At this position, a series of Shino exchange and Shino joining operations are performed in sequence. The work will be described below with reference to FIG.

First of all, the small bobbin 1c in the front row is in a state where the number of remaining Shinobu is small and Shino exchange is required (Fig. 22 (1)).
When this state is reached, as shown in FIG. 22 (2), the full bobbin exchange head 52 corresponding to directly below the full bobbin 1a hung on the bobbin hanger 24 of the spare rail 15 is lifted by the lifting mechanism 31. Full bobbin replacement head 52
Peg 53 of the full bobbin 1a fits under the full bobbin 1a
Remove a from the bobbin hanger 24. The full bobbin exchange head 52 on which the full bobbin 1a is placed descends to return to the original position shown in FIG. 22 (1), and the ejection nozzle 62 causes the ejection nozzle operation mechanism to move as the full bobbin exchange head 52 descends. Thus, the ejection nozzle 62 stops at a position where the suction port of the ejection nozzle 62 corresponds to the height position of the tip of the full bobbin 1a that has risen and descended (FIG. 22 (3)). Next, the motor 5 of the peg rotation mechanism built in the full bobbin exchange head 52.
4 rotates counterclockwise when viewed from above, and every other full bobbin whose shin end is on the opposite side of the nozzle 62 is rotated 180 ° in the winding direction in advance, and the shin ends of those full bobbins are taken out. It is moved to the nozzle 62 side. Then the motors 54, 57
Is rotated clockwise to rotate the six full bobbins in the rewinding direction, and the suction force by the blower 23 acts on the outlet nozzle 62. As a result, the suction ports of the ejection nozzles 62 reliably suck the corresponding shino ends of the full bobbins to eject the shino of the full bobbin 1a (FIG. 22 (4)). While continuing the rotation of the full bobbin 1a and the suction of the lead-out nozzle 62, the lead-out nozzle 62 descends and returns to its original position, at which time the drawn-out Shino enters the Shino guide groove 173 of the Shinotsu head 60 (Fig. 22). (Five)). The solenoid 185c of the Shinotsu head 60 is energized and the Shino gripping lever operates to grip the full bobbin Shino between the Shino gripping part 175 and the nip piece 176, and at the same time, the Shinotsu head in the downward vertical state operates the Shinotsu head. By the mechanism, the full bobbin 1a is brought into a substantially horizontal state by the mechanism, and at this time, the shino of the full bobbin 1a is caught by the comb mounted inside the tip of the outlet nozzle 62, and the gripping point of the shin joint head 60 and the outlet nozzle 62.
Is cut between and to form the Shino end (Fig. 22).
(6)). Next, the Shino joint head 60 advances toward the drafting unit 5 of the spinning machine by the Shino joint head operating mechanism while gripping the full bobbin on which the Shino end is formed. The Shinotsu head 60 is stopped while moving forward, and is moved to the trumpet 6 side (right side in the case of FIG. 4) where the small bobbin Shino is introduced by the Shinotsu head lateral movement mechanism 61 by 1/2 spindle pitch. It moves laterally by an amount and takes 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 the forward movement to reach the upper end of the trumpet 6 at the Shino end of the full bobbin. Go forward. At that time, the shin of the small bobbin being spun enters the shin guide groove 173 of the shin joint head 60 and overlaps with the shin of the full bobbin. When the Shinobu head 60 moves forward, the full bobbin is rotated counterclockwise by the peg rotation mechanism of the full bobbin replacement head 52, and the Shino is unwound to prevent cutting of the Shinobu caused by the forward movement of the Shinobu head 60. At the same time, the shining plate 58 is slightly raised by the shining plate operating mechanism in order to hold the slack of the unwinding. After the Shinotsu head 60 stops moving forward, the solenoids 185a and 185b of the Shinotsu head 60 are energized, the Shino gripping lever turns to the neutral position and releases Shino's grip of the full bobbin, and the released full bobbin 1
The Shino of a is guided by the Shinobu of the small bobbin being spun and is inserted into the trumpet 6 together with the Shinobu, and after the Shino end of the full bobbin 1a is gripped by the back roller 5a of the drafting unit 5, the Shino joint head 60 The solenoid 185b is energized, and the Shino gripping lever 174 further rotates to grip the Shinobu of the small bobbin between the grip holding unit 175 and the nip piece 177. Since the Shinobu head of the small bobbin is held by the Shinotsu head 60, it is drafted and cut with the back roller (Fig. 22 (7)). The full bobbin 1a, which has finished the piecing joint, is again raised by the full bobbin exchange head 52 to a position where it cannot be mounted on 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 shin, and prevents the shin from being cut due to the rising of the full bobbin 1a. The slack of the full bobbin 1a, which has been lifted up near the roving guide 2 and unwound, is held. During this time, Shinotsu head 6
0 solenoids 185a and 185d are energized and the shino gripping lever 174
Is moved to the neutral position, whereby the Shino gripping lever 174 releases the Shino grip of the small bobbin and at the same time the Shino joint head 60 retracts and stops until the Shin bobbin 1a moves away from the Shino joint head 60 ( Figure 22 (8)). The small ball bobbin exchange head 55 moves forward to and immediately below the small ball bobbin in the front row of the creel by the forward / backward movement mechanism and the lifting mechanism, and removes the small ball bobbin 1c from the bobbin hanger 19 in the front row (second
2 (9)). The small ball bobbin exchange head 55 on which the small ball bobbin is placed descends (Fig. 22 (10)), retracts and returns to its original position, and as a result, the outer periphery of the small ball bobbin is stroked with the plate 211.
Be contacted. (Fig. 22 (11)). The peg rotation mechanism built into the small bobbin exchange head 55 rotates the small bobbin clockwise as viewed from above to wind up the cut shinobi. At the time of winding, the lifting plate 204 scoops up the side of the small bobbin to the side of Shino that is hanging near the small bobbin. As a result, the remaining Shinohana hanging plate 211 and the lifting plate 204 hanging from the small ball bobbin are reliably wound around the outer circumference of the small ball bobbin. The small bobbin changing head 55 returns to its original position, and the full bobbin changing head 52 descends and returns to its original condition. 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 full bobbin exchange head 52.
Keep the slack of Shino caused by the descent of. After the Shino hanging plate 58 is lifted to the maximum, the Shino hanging plate lateral movement mechanism 59 laterally moves the Shin bobbin 1a Shino through the roving guide 2 installed in the spinning machine. At the same time, the Shinotsu head 60 moves back and returns to its original position. During the backward movement, the Shinotsu head 60 stops the backward movement, moves laterally, and returns to the position corresponding to the bobbin of the creel when viewed in the longitudinal direction of the spinning machine (Fig. 22 (12)). The Shinatsugi head 60 that has finished retreating is returned from the substantially horizontal state to the vertical state (FIG. 22 (13)). The full bobbin changing head 52 advances to just below the bobbin hanger 19 in the front row and rises to reach the bobbin hanger 19 with a full bobbin 1.
Attach a. At this time, the full bobbin 1a is rotated by an appropriate amount in the clockwise direction by the peg rotation mechanism of the full bobbin changing head 52 to properly maintain the slack of the shin caused by the forward movement and ascent of the full bobbin changing head 52. After that, small ball bobbin replacement head 5
5 moves forward to the position immediately below the spare bobbin hanger 24 on the spare rail 15 and rises to mount the small bobbin on the bobbin hanger 24. The shining plate 58 descends and laterally moves midway to return to the original position (Fig. 22 (14)). The small bobbin changing head 55 descends, retracts and returns to its original position, and the full bobbin replacing head 52 descends, retracts and returns to its original position (Fig. 22 (15)).

Thus, one cycle of Shino exchange work is completed, and Shino exchange 5
In the case of 0, the bobbin hangers 19 in the front row are laterally moved by 6 pieces and stopped, and the shino exchange work is sequentially repeated from one end to the other end of the spinning machine.

The Shino exchange 50 may perform Shino exchange and Shino joining work in the following procedure. Full bobbin replacement head 52 is moved up to full bobbin 1
After fitting a into the peg 53 (FIG. 22 (2)), the small bobbin changing head 55 is moved forward and raised to 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 formed by spinning the small bobbin 1c in the positional relationship shown in FIG. 22 (11). Next, the full bobbin replacement head 52 is lowered to expose the shino end from the full bobbin 1a in the same manner as described above, and then the shino end is gripped by the shino joint head 60 and guided above the trumpet to perform the shino joint. After the Shino-Join ends, the full bobbin 1a is hung on the front row bobbin hanger 19, and the small bobbin 1c winds up the Shinobu hanging from the roving guide 2 and then the spare bobbin hanger 24 of the spare rail is provided.
To hang.

In this way, when the small bobbin 1c being spun is placed on the peg 56 of the small bobbin exchange head 55 to perform piecing joint, the shining small bobbin extending from the small bobbin 1c to the roving guide 2 is small. Rotate the small bobbin 1c counterclockwise so that it does not interfere with the full bobbin 1a in front of the bobbin 1c to have an appropriate amount of slack, and at a speed equivalent to the amount of spinning of the small bobbin until the end of the splicing work. It is necessary to unwind and rotate 1c. However, according to this method, when the full bobbin 1a and the small bobbin 1c are replaced after the completion of the connection in the embodiment shown in FIG. 22, the full bobbin 1a is retracted upward in order to avoid interference between both bobbins (FIG. 22). (9) ~ (1
The operation of the full bobbin 1a of 1) can be stratified.

In the present 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 laterally moved by 1/2 spindle pitch during the forward movement of the Shino-joint head 60 so as to correspond to the trumpet 6. But this is 1/2
For the horizontal movement of the spindle pitch, the same spinning machine first moves to the left side, and then to the right side at the next shino exchange.
That is, the left lateral movement and the right lateral movement are alternately performed to move the small bobbin 1c above the trumpet 6 on the side where the small bobbin 1c is spun.
It goes without saying that you should guide 0. If the Shino joint head 60 and the ejection nozzle 62 are designed to be laterally moved by the spindle pitch, and the Shino end of the full bobbin 1a is ejected at a position corresponding to the trumpet 6, the lateral movement of the Shino joint head 60 during the forward movement is performed. It is not necessary to perform the operation of. In this case, before the Shinobashi is ejected from the full bobbin 1a, the Shino joint head 60 and the ejection nozzle 62 are moved to a position corresponding to the trumpet 6 on which the small bobbin 1c is spun. Another nozzle 6
2 is provided at a position corresponding to the trumpet 6
When 0 is positioned so that it can be moved by the spindle pitch, the horizontal movement of the Shinobu head 60 during the forward movement is alternately performed by the spindle pitch and without horizontal movement.
Further, if the suction airflow of the outlet nozzle 62 is made to generate a swirling airflow in the direction opposite to the twist of the Shino, the Shino end sucked from the full bobbin 1a into the outlet nozzle 62 is untwisted and separated. Incidentally, when the full length bobbin 1a is exposed, the full length may be attached to a brush, a moquette or the like. If the brush for dispensing and the suction port of the dispensing nozzle 62 are designed to be able to move up and down from the standby position of the Shino exchange 50 to a position facing the outer circumference of the full bobbin 1a hanging on the spare rail, the brush is suspended on the spare rail. With ゝ, the Shinobashi end of the full bobbin 1a is spouted, the Shinobashi is spliced, and after the Shino splice is finished, the small ball bobbin 1c can be removed and the Shinobashi exchange can be performed. Since the size must be increased, the Shino exchange 50 becomes large.

In the above embodiment, it is needless to say that it may be carried out in units of a plurality of four or eight, which is a practically preferable unit, in which six pieces are replaced.

〔The invention's effect〕

In the Shino exchange machine of the present invention, the full bobbin is placed on the peg of the full bobbin replacement head that can be rotated in the forward and reverse directions. Since it is made to squeeze out, the full bobbin's shino end / sword end is surely performed, and the sash end is guided by guiding it to the trumpet and superimposing it on the small ball bobbin being spun, so the shino splice is also sure Done. When the full bobbin and the small bobbin are exchanged, the pegs of the full bobbin and the small bobbin are moved forward and backward in accordance with the movement of the exchange head, so that there is no possibility of a break in the exchange. Therefore, the Shino exchange machine of the present invention can securely perform Shino exchange and Shino joining without breaking Shino and enables complete automation of Shino exchange, and can greatly save labor in the spinning factory. Further, since a plurality of this spinning exchanges are performed at the same time, the spinning exchanges per spinning machine can be performed quickly, and a single spinning exchange machine can be used for a large number of spinning machines, so that the equipment cost is low and it is economical. .
