The up-and-down body 37 is moved up and down by moving the up-and-down body 37 in both up and down directions using. 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 by the main body 51 of the Shino exchange 50 through the chain 33b and the chain wheel 34a. It Chain wheels 35a, 35b are attached to both ends of the shaft 34, and one end of each of the above-mentioned 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 is connected to the main body 51. The chain wheels 39a, 39b rotatably arranged above are connected to the upper and lower parts of the lifting body 37, and thus the rotation of the shaft 34 achieves the vertical movement of the lifting body 37. At that time, since the lifting body 37 is slidably fitted to the guide members 38a and 38b provided vertically to the main body 51, accurate movement in the vertical direction is ensured. Next, the back-and-forth motion of the full bobbin changing head 52 is performed by the full bobbin changing head moving mechanism shown in FIG. A housing 77 is provided above the lifting / lowering body 37, and rotation of a motor 86 in the housing 77 oscillates an arm 82 via a speed reducer 85 and gears 84, 83, and the oscillating motion is provided at the tip of the arm 82.

The upper peg 53 can be moved back and forth with respect to the spinning machine while keeping the posture in the vertical direction, and can be moved to a position directly below the spare bobbin hanger 24 and a position directly below the front row bobbin hanger 19.

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, six pegs 53 (53a, 53b, 53c, 53d, 53e, 53f) are arranged on the change bar 71 of the full bobbin replacement head 52 at intervals of 2 spindle pitches. It 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 in detail later regarding the operation of Shino exchange. Further, as shown in FIG. 10, these pegs 53 can be rotated by 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, the Shinano end of the full bobbin wound by the roving frame has a 180 ° phase difference between the front row and the back row of the flyer presser position in the roving machine, so the front row is 180 ° out of phase with the rear row. Located on the other side. Therefore,
Put every other full bobbin in the front and rear rows that has been doffed by the roving machine in a row and rearrange them in a single row, and suspend the full row bobbin on the spare rail 15 using the bobbin carriage 17. Shino end 1ae of full bobbin 1a is positioned on the opposite side every 180 ° as shown in FIG. 10 (A). Ie first

In this state, when the six full bobbins are simultaneously returned and rotated in order to be ejected by the ejection nozzle 62,
Since the distance between full bobbins is generally small, the ejection nozzle 62
By the time the Shino end, which was located on the opposite side, reaches the ejection nozzle 62, the Shino end adheres to the peripheral surface of the adjacent full bobbin and is wound around the full bobbin, making it impossible to eject. is there. Therefore, the full bobbin 1a at the positions (b), (d), and (f) is rotated 180 ° in the winding direction in advance at the beginning of the operation of the shino exchange, and six bobbins are provided as shown in FIG. 10 (B). Full bobbin Shinohana 1ae
Are aligned so as to face the dispensing nozzle 62, and then 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.

The pivot shaft 145 is rotatably supported by a pair of left and right supports 51e, 51e fixed to the main body 51 and slightly movable in the longitudinal direction (left and right direction in FIG. 1). The lower end of the inner link 146 is loosely fitted in the inner link 146, and the lower end of the outer link 147 is fixed. A sector gear 144 is fixed to the end of the pivot shaft 145, and the sector gear 144 meshes with a gear 141a integral with the swing arm 141. A pin 151 is provided on the upper end of the outer link 147,
It is engaged with the long hole 150a of the connecting link 150.

The upper end of the inner link 146 rotatably supports a pin 149 integrally provided on the end surface of the Shinobu head support bar 148, and the upper end of the connecting link 150 is fixed to the pin 149. The joint head support bar 148 is a connecting link 150.
It is possible to rotate about the pin 149 by swinging.

Therefore, when the swing arm 141 rotates counterclockwise about the pin 143 due to the downward movement of the rod 197 for operating the Shinanotsu head, the outer link 147 pulls the spring 153 via the sector gear 144 and the pivot 145. By swinging clockwise against the force, the pin 151 at the upper end of the outer link 147 is pushed to the right and the connecting link 150 is rotated counterclockwise around the pin 149. As a result, the Shinotsu head support bar 148 rotates counterclockwise with the Shinotsu head 60. This pivoting movement is linked to the link 150
From the position shown in FIG. 8 to the opposite position symmetrical to the vertical line passing through the pin 149, so that the joint head 60 is in a substantially horizontal position. Furthermore, when the rod 97 for operating the Shinotsu head moves downward and the outer link 147 further rotates clockwise, the pin 151 comes into contact with the lower end of the elongated hole 150a, and thereafter the pin 149 is pulled to the right by the connecting link 150. The inner link 146 is rotated about the pin 145 by being twisted, and the Shino joint head 60 that is oriented in the horizontal direction is directed toward the Shino R from the small bobbin 1c being spun along the locus indicated by 154. I will proceed.

The position of the full bobbin in the spinning machine and the position of the drafting unit 5 are usually displaced by 1/2 pitch of the spinning spindle as shown in FIG. Therefore, when the Shinobu of the full bobbin is exposed, and the Shinobu head 60 is grasped and moved to the drafting unit 5, the Shinobu of the Kodama bobbin to which the Shinotsu head 60 should be spliced is introduced. It is necessary to move laterally to the 5 side by 1/2 spindle pitch. Therefore, as shown in FIG. 1, a Shino joint head lateral movement mechanism 61 is provided to move the pivot shaft 145. The Shinotsuji head lateral movement mechanism 61 has a speed reducer 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, and swings around a pin 155a. The arm 155 is moved, 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 Shino joint head 60 shown in FIGS. 14 and 15 traverses the Shino joint head 171 having a Shino guide groove 173 formed at its tip and the Shino guide groove 173 in a plane parallel to the upper surface of the main body 171. And a reciprocating shino grasping lever 174. The main body 171 is fixed to a Shino joint head support bar 148 having a U-shaped cross section.
The shining lever 174 is rotatably supported by a pivot pin 178 fixed to the main body 171 in the vicinity of the center thereof, 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 operating bar 182, and the operating bar 182 has a pin 179 at the tip thereof.
An actuating member 181 having an opening for accommodating is fixed. Nip pieces 176 and 177 having shining gripping surfaces 176a and 177a facing shining gripping surfaces 175a and 175b on both sides of shining gripping portion 175 at the tip of shining grip lever 174 respectively have nip pieces 176 and 177 in shining guide groove 173 and are on the upper surface of main body 171 at both positions. It is fixedly installed in. Body 171
A triangular shino guide opening 172 for guiding the shino to the shino guide groove 173 is formed at the tip of the shino guide groove 173, and one side surface of the shino guide opening 172 receives air sent through the conduit 184 to the shino guide groove 173.
An opening of a nozzle 183 that ejects downward is provided.

The air flow ejected from the nozzle 183 serves to extend the bending of the tip of the full bobbin which is superposed on the tip of the spinning small bobbin. In FIG. 14 (A), the operating bar 182 moves to the right and the shining surface 175a of the shining lever 174 and the nip piece 177 are moved.
The position of the Shino gripping lever 174 in the standby state for gripping Shino (not shown) of the small bobbin between the Shino gripping surface 177a and the Shino gripping surface 177a is shown. The full bobbin 1c and the outlet nozzle in the state in which the Shinotsu head 60 is positioned in the vertical position of the Shinotsu head 60 described with reference to FIG.
The Shino extending between 62 is introduced into the Shino guide groove 173 through the Shino guide opening 172, and then the Shino gripping lever 174 rotates the Shino gripping part 175 to the right as in the state of FIG. 14 (C). Shino grasping lever 174
And the nip piece 176 is gripped, and while the Shinobu head 60 is moved from the vertical position to the horizontal position, the Shino between the lead-out nozzle 62 and the Shino gripping lever 174 is cut like a writing brush on the downstream side of the gripping point. As a result, the tip end of the writing brush, which is to be overlapped with the tip of the small bobbin being spun, is located in the tip guide groove 173. By repeating the movement from the vertical position to the horizontal position, the monofilament entangled at the tip of the shino is removed, and the brush tip shape of the tip of the shino can be made uniform. In this state, the Shinotsu head 60 has a solid line 15 in FIG.
Along with the locus shown by 4, it is brought closer to Shino R of the small bobbin being spun, and is laterally moved to the right or left in FIG.
As a result, the Shino R of the small bobbin being spun on the trumpet 6 is introduced into the Shino guide groove 173, and the Shino end of the full bobbin is superposed on the Shino R of the small bobbin. Next, as shown in FIG. 14 (B), the shino grasping portion 175 of the shino grasping lever 174 rotates to the left and is moved to the neutral position, whereby the shino end of the full bobbin is guided to the shino R of the small bobbin. It is then introduced into the trumpet 6 in a polymerized state. After that, when the Shino end of the full bobbin is introduced into the back roller 5a of the drafting unit 5, the Shino gripping unit 175 is rotated to the left as much as possible as shown in FIG. Gripping surface 175a of the left grip 175 and gripping surface 177a of the left nip piece 177.
Hold Shino R of the small bobbin between and. In this way, since the downstream shino of the hinoki joint head 60 is spun toward the drafting portion 5, the joined portion advances to the downstream side, and the shino R upstream of the hinoki joint portion 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 operating bar 182, the plungers 189 of four operating bar sliding solenoids 185 fixed to the Shinotsu head supporting bar 148 are L-shaped members 188, pins 200 and holes 18.
Connected via 6 respectively. The plunger 189 can move freely when the solenoid 185 is not energized, and the plunger 189 is retracted when the solenoid 185 is energized. The pin 200 has an operating bar 182 through a hole 186.
To transmit the movement of the plunger to the operating bar 182. At that time, the shape of the hole 186 with which the pin 200 is engaged is such that the holes 186a, 186d corresponding to the solenoids 185a, 185d are long holes in the moving direction of the operating bar 182, and the holes 186b, 186c corresponding to the solenoids 185b, 185c are The long hole is formed in a direction perpendicular to the moving direction of the operating bar 182. As shown in FIG. 17 (A), when the solenoid 185c is energized (ON), the plunger 18
9 moves to the right to indicate the operating bar 182 is a pin 200c drawn to the solenoid 185c to move as indicated by the arrow C to the right by the arrow X _1, the distal end 175 of the result Shino gripping lever 174
Rotates to the left and contacts the nip piece 176 to grip the full bobbin (see FIG. 14 (C)). Next, in order to set the shino gripping lever 174 to the neutral position shown in FIG. 14 (B), the solenoid 185d is set as shown in FIG. 17 (B).
By energizing (ON) and moving the pin 200d in the direction of arrow D, the operating bar 182 is moved in the direction of arrow X2. At the same time, the solenoid 185a is energized and the solenoid 185a
Since the plunger 189 is kept in the retracted position, the actuation bar 182 is positioned at the neutral position with the right end 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 small bobbin during spinning shown in FIG. 14 (A),
As shown in FIG. 17 (C), the solenoid 185b is energized (O
N), and move the pin 200b in the direction of arrow B by retracting the plunger 189 to move the actuating bar 182 in the direction of arrow X _3.

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

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 Shinotsuji head 60 has two levers, a full bobbin Shino lever 174a and a Shino R lever 174b being spun from a small bobbin, as Shino gripping levers. Is different from Shinotsu head 60 in FIG. Therefore, corresponding 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 as shown in FIGS. In the same manner as in the case of the Shinotsu head 60, the Shino end of the full bobbin is superposed on the Shino R of the small bobbin to complete the Shino join.

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 Shinobu of the full bobbin that has finished Shinotsu 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 a single plate extending in the longitudinal direction of the Shino exchange 50. Shino hanging plate operating mechanism is the 6th
The downward movement of the rod 95 for operating the shining plate by the shining cam 68 of the operating mechanism 65 shown in the figure
The desired movement locus is given to the Shino hanging plate 58 by the movement of the link mechanism in which 1 and the inner link 102 are merged. That is, the sector gear 104 is pivotally attached to the main body 51 via a pin 109, and is rotated clockwise about the pin 109 by the downward movement of the rod 95 for operating the hanging plate, the movement of which is opposite to that of the selector gear 105. Produces clockwise rotation. The sector gear 105 is fixed to a shaft 112 which is rotatably and slidably supported in the longitudinal direction by a support 103 attached to the main body 51, and the upper end of the outer link 101 is fixed to the shaft 112. Has been done. 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 at the rear end of the support lever 108. A shaft 117 is rotatably and axially movably supported by a support body 103, and one end of a connecting link 106 is rotatably attached to the shaft 117 and the other end is rotatably attached to the shaft 112, and the axial movement of the 112 is performed. Is transmitted to the shaft 117. Then, the upper end of the inner link 102 is fixed to the shaft 117, and the inner link 10
The lower end of 2 is connected to the connecting link 107 and the pin 113. The pinion 114a planted in the connecting link 107 is wedged with the pinion gear 114, and the pin 115a planted in the support lever 108 is pinned to the pinion 115a.
It is wedged and the small gears 114 and 115 mesh with each other. 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 shinko of the full bobbin that has been spliced to the roping 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. Sector Gear 105
Outer link 101 and inner link 1 with the counterclockwise rotation of
Both 02 rotate counterclockwise, and when approaching the swinging end of the outer link 101, the connecting link 107 has a pin 114a because of the connecting length of the outer link 101, the inner link 102, and the connecting link 107.
Is rotated counterclockwise with the fulcrum as a fulcrum, and the small gear 11
Since the small gear 115 meshing with 4 is rotated clockwise, the tip of the shining plate 58 moves as shown by the locus 116 in FIG. 9, and when it reaches the swing end of the outer link 101, the roving guide 2 The shining plate 58 is inclined to the machine base side above, and guides the full bobbin into the roving guide 2.

Next, a mechanism for laterally moving the Shino hanging plate 58 will be described.
The shining plate 58 is the roving guide 2 shown in FIG.
20mm for hanging the full bobbin 1a on the claw part 2b of
In order to move it, it is moved by the horizontal hanging plate horizontal moving mechanism 59 shown in FIG. The horizontal hanging plate lateral movement mechanism 59 has a motor 117 with a reduction gear fixed to the main body 51, a worm 118 that is rotated by the motor 117 via a gear 117a, and a worm wheel that meshes with the worm 118 at one end. , An arm 119 for selectively swinging to the right or left in FIG. 1 around the pin 119a to laterally move the shaft 112 of the shining plate operating mechanism. 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 in a state where the Shino hanging plate 58 is lifted to guide the Shino into the roving guide 2, and as a result, the Shino is hooked on the claw portion 2b of the roving guide 2.

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 machine 50, the remaining Shinobu of the small ball bobbin that is cut after being connected by the Shinotsu head 60 hangs down from the small ball bobbin 1c. The small ball bobbin 1c after winding the hanging samurai is a spare bobbin hanger on the spare rail 15.
After being moved to 24, the small bobbin 1c is usually suspended and moved from the spare rail 15 to the remaining shinobo treatment step for the next shinowaki work. At that time, if you do not wind the remaining Shinoshino around the Kodama bobbin 1c, the remaining Shinoshino will hang down from the Kodama bobbin 1c again during the movement, and sometimes the weight of the hanging Remaining Shinoshino itself will cause all of the remaining Shinoshino on the Kodama bobbin 1c to become small balls. Dropped from bobbin 1c,
An unfavorable phenomenon such as 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 of samurai hang down again from the small ball bobbin 1c, 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 side of the small ball bobbin to the side of the small ball bobbin while stroking the outer circumference of the small ball bobbin with the stroking plate 211.In this state, rotate the small ball bobbin in the winding direction and drop 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 a small bobbin exchange head front-back movement mechanism. The small bobbin changing head back and forth moving mechanism has the same structure as the full bobbin changing head back and forth moving mechanism described with reference to FIG.
The small bar bobbin change bar 70 arranged at intervals of the spindle pitch uses the inner link 201 and the outer link 202 to the position shown by the solid line in FIG. 19 and the small bobbin 1C on the spinning machine shown by the chain double-dashed line. It is movable between the engageable positions. As described above, since the small ball bobbin exchange head lifting mechanism is provided on both sides of the full bobbin replacement head lifting mechanism 31, the small ball bobbin change bars 70 are provided corresponding to the small ball bobbin exchange head lifting mechanism, respectively. Therefore, one lifting plate 204 is also provided for each small bobbin change bar 70. The lifting plate 20
4 is a change bar 70 as shown in FIGS. 19 and 20.
Is formed in a plate shape extending in parallel with and has a notch 204a above which guides the remnants.
Is 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 is rotatably attached by a pin 206 to a support bracket 210 extending upward from the change bar 70 at an intermediate position thereof. The mounting position of the support lever 203 to the support bracket 210 is such that when the change bar 70 as shown by the chain double-dashed line on the right side of FIG. 19 is below the small bobbin 1c on the spinning machine, the lifting plate 204 and the support lever 203 are attached. As shown in the drawing, the pin 206 turns clockwise around the pin 206 depending on the weight of the right side of the mounting position, 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. The stopper 207 is
19 When the change bar 70 moves to the position shown by the solid line on the left side of FIG.
It is configured to abut against 7 and rotate the support lever 203 counterclockwise about the pin 206 to move the lifting plate 204 to the side of the small bobbin 1c.

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 via 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 to the Shino surface is lifted when the small bobbin 1c reaches the rearmost position (the position on the left side in FIG. 19). Lift the plate 204 to the side of the small bobbin 1c.Plate 204 is lifted to the side of the small bobbin 1c and wound on the small bobbin 1c by the rotation of the small bobbin 1c. The position is adjusted by using the adjusting bolt 213 so that it is wound while being attached. Thus, when the small bobbin 1c with the hanging sash moves from the right side position to the left side position in Fig. 19 together with the change bar 70 by the small bobbin longitudinal movement mechanism, the lifting plate 211 rotates counterclockwise as described above. Scoop up the side of Shino that hangs near Kodama bobbin 1c to the side of Kodama bobbin 1c, and at the same time rotate it to wind the remaining Shinobu.
Since 1 touches, the hanging samurai is a small ball bobbin 1c
Will be surely wrapped around.

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 ball 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 the case of performing the Shino exchange in a broad sense, that is, the replacement of the full bobbin and the small bobbin and the work of the Shino joint using the Shino exchange 50 having the above-described configuration. First, as shown in FIG. 3, the bobbin hung on the bobbin hanger 19 in the front row of the creel of the spinning machine becomes the small bobbin 1c as the spinning progresses, and the bobbin hung on the bobbin hanger 20 in the rear row is middle. When the ball bobbin 1b is reached, 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 full bobbin 1a is suspended from the spare bobbin hanger 24, which is arranged in advance on the spare rail 15 of the spinning frame so as to face the position of the bobbin hanger 19 in the front row of the spinning frame. If the bobbin suspended on the bobbin hanger 20 in the rear row becomes a small piece and shino exchange is necessary, the small bobbin is arranged in the front row in advance using the shino exchange machine 10 described above. Keep it.

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 has a small amount of shinko remaining, and is in a state requiring shinwa exchange (Fig. 22 (1)). When this state is reached, as shown in FIG. 22 (2), the full bobbin exchange head 52 corresponding to the position just below the full bobbin 1a that is hung on the bobbin hanger 24 of the spare rail 15 is lifted by the elevating mechanism 31 and lifted up. The peg 53 of the bobbin exchange head 52 is fitted to the lower portion of the full bobbin 1a to remove the full bobbin 1a from the bobbin hanger 24. The full bobbin exchange head 52 on which the full bobbin 1a is placed returns to the original position shown in FIG. 22 (1), and the outlet nozzle 62 is driven by the outlet nozzle operating mechanism in accordance with the lowering of the full bobbin exchange head 52. The lead-out nozzle 62 stops at a position where the suction port of the lead-out nozzle 62 corresponds to the height position of the raised end of the full bobbin 1a (Fig. 22 (3).
The motor 54 of the peg rotation mechanism built into the full bobbin replacement head 52 rotates counterclockwise when viewed from above, and every other full bobbin whose shino end is on the side opposite to the outlet nozzle 62 is wound in advance. Rotate by 180 ° and move the shino ends of those full bobbins to the ejection nozzle 62 side. After that motor 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 dispensing nozzles 62 reliably suck the shino end of the corresponding full bobbin and the full bobbin 1a.
Say Noshino (Fig. 22 (4)). While continuing rotation of the full bobbin 1a and suction of the outlet nozzle 62, the outlet nozzle 62
Moves down and returns to its original position, at which time the Shino enters the Shino guide groove 173 of the Shinotsu head 60 (Fig. 22 (5)). 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, it becomes a horizontal horizontal state, and at that time, the Shinobu of the full bobbin 1a is caught by the comb mounted inside the tip of the ejection nozzle 62, and cuts between the grip point of the Shinobu head 60 and the ejection nozzle 62. Then, the Shino end is formed (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 formed with the Shino end. The Shinotsu head 60 stops moving forward while it is moving forward, and moves toward the trumpet 6 side (the right side in FIG. 4) where the Shinobu bobbin Shino is introduced by the Shinotsu head horizontal movement mechanism 61 for 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 Shinobu of the small bobbin being spun into the Shino guide groove 173 of the Shinotsu head 60 and overlaps with the Shinobu 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 advance of the Shinobu head 60. , Shino hanging plate 58 to hold the loosened Shino slack at the same time
Is raised a little by the Shino hanging plate operating mechanism. After the Shinotsu head 60 stops moving forward, the solenoid of the Shinotsu head 60
185a, 185b is energized, the Shino gripping lever turns to the neutral position and releases the Shinobu of the full bobbin, and the Shino of the released full bobbin 1a is guided by the Shino of the small bobbin being spun and After being inserted into the trumpet 6 and the Shino end of the full bobbin 1a is gripped by the back roller 5a of the drafting unit 5, the solenoid 185b of the Shino joint head 60 is energized, and the Shino grip lever 174 further rotates to rotate the Shino grip unit 175. The small bobbin is gripped between the nip piece 177 and the nip piece 177. Since the Shinobu of the small bobbin is gripped by the Shinotsu head 60, it is drafted and cut with the back roller (Fig. 22 (7)). The full bobbin 1a, which has completed the piecing joint, is again raised by the full bobbin replacement head 52 to a position where it cannot be mounted on the spare bobbin hanger 24, and then stopped. At that time, the full bobbin 1a is moved by the peg rotation mechanism of the full bobbin replacement head 52.
Rotates counterclockwise and unwinds the Shinobu to prevent the Shinobu from cutting due to the lifting of the full bobbin 1a, and at the same time, the Shino hanging plate 58 further rises near the roping guide 2 and is unwound. Holds Shino's slack in 1a.
During this time, the solenoids 185a and 185d of the Shinobu head 60 are energized to move the Shino gripping lever 174 to the neutral position, whereby the Shino gripping lever 174 releases the Shino grip of the small bobbin and the Shinobu of the full bobbin 1a moves. The Shinotsugi head 60 retracts and stops until it comes off the Shinotsuji head 60 (Fig. 22 (8)). The small bobbin changing head 55 moves forward and directly below the small bobbin in the front row of the creel by the forward / backward movement mechanism and the lifting mechanism, and moves up from the bobbin hanger 19 in the front row to the small bobbin.
Remove 1c (Fig. 22 (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 contacts the padding plate 211. (Fig. 22 (11)). The small ball bobbin is rotated by the peg rotation mechanism built in the small ball bobbin exchange head 55 in a clockwise direction when viewed from above, and winds the cut Shino. At the time of winding up, the lifting plate 204 scoops up the side of the small ball bobbin to the side of Shino that is hanging near the small ball bobbin. As a result, Zanshino Haneda Plate 211 and Lifting Plate 2 hanging from the small ball bobbin
By the function of 04, it is reliably wound around the small bobbin. The small bobbin exchange head 55 returns to its original position, and the full bobbin exchange head 52 descends and returns to its original state. 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 replacement head 52 to wind up the full bobbin replacement 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 and hooks Shino of the full bobbin 1a through the roving guide 2 installed in the spinning machine. At the same time, the Shinetsutsu head 60 retreats and returns to its original position. During the backward movement, the Shinotsu head 60 stops the backward movement, moves laterally and returns to a position corresponding to the bobbin of the creel when viewed in the longitudinal direction of the spinning machine (Fig. 22 (1
2)). The Shinotsu 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 the position just below the bobbin hanger 19 in the front row and rises to mount the full bobbin 1a on the bobbin hanger 19. 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 upward movement of the full bobbin changing head 52. After that, the small ball bobbin changing head 55 advances to just below the spare bobbin hanger 24 on the spare rail 15 and moves up to move up to the bobbin hanger.
Attach a small ball bobbin to 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 changing head 52 descends, retracts and returns to its original position (Fig. 22 (1
Five)).

Thus, one cycle of Shino exchange work is completed, Shino exchange mechanism
The number 50 of the bobbin hangers 19 in the front row is 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 59 may perform Shino exchange and Shino joint work in the following procedure. After the full bobbin replacement head 52 is lifted and the full bobbin 1a is fitted to the peg 53 (Fig. 22 (2)), the small bobbin replacement head 55 is advanced and lifted to remove the small bobbin 1c from the front row bobbin hanger. Return to 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 shining end from the full bobbin 1a in the same manner as described above, and then the shining end is gripped by the shining joint head 60 and guided to the upper side of the trumpet to perform the shining joint. After the Shino-Join is completed, the full bobbin 1a is hung on the front row bobbin hanger 19, and the small ball bobbin 1c is wound on the shinobi hanging from the roving guide 2 and then hung on the spare bobbin hanger 24 on the spare rail.

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 the piecing joint, the shining 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, and give it an appropriate amount of slack. It is necessary to continue unwinding and rotating the bobbin 1c. However, according to this method, the operation of retracting the full bobbin 1a upward in order to avoid interference between both bobbins at the time of replacement of the full bobbin 1a and the small bobbin 1c after completion of the connection in the embodiment of FIG. 22 (FIG. 22) (Operation of full bobbin 1a of (9) to (11))
Can be omitted.

In the present embodiment, since the Shinotsu head 60 is provided so as to correspond to the center of the full bobbin 1a, it is
The horizontal movement of 1/2 spindle pitch is made to correspond to the trumpet 6. This horizontal movement of 1/2 spindle pitch is the same spinning machine, and if it is moved to the left side first, it will be changed at the next shino exchange. To move to the right side. That is, it goes without saying that the left lateral movement and the right lateral movement are alternately performed so that the Shinotsu head 60 is guided above the trumpet 6 on the side where the small bobbin 1c is spun. Shinobushi head 60 and outlet nozzle 62 are designed to be able to move laterally by the spindle pitch, and full bobbin 1a at the position corresponding to trumpet 6
If the Shino end of the Shino joint head 60 is exposed, it is not necessary to perform the lateral movement operation of the Shino joint head 60 during the forward movement. In this case, the Shino joint head 60 and the ejection nozzle 62 are moved to a position corresponding to the trumpet 6 spun by the small bobbin 1c before the Shinobashi is ejected from the full bobbin 1a. Further, when the lead-out nozzle 62 is provided at a position corresponding to the trumpet 6 and the Shino-joint head 60 is positioned so as to be movable by the spindle pitch, the lateral movement of the Shino-joint head 60 during the forward movement is set to the lateral movement of the spindle pitch and no lateral movement. It will be done alternately. Further, when 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. In addition, the tip of the full-length bobbin 1a may be attached to a brush, a moquette, or the like. Then, if it is designed so that the brush for dispensing and the suction port of the dispensing nozzle 62 can be moved up and down from the standby position of the Shino exchange 50 to a position facing the outer periphery of the full bobbin 1a suspended on the spare rail, the brush is suspended on the spare rail. With ゝ, you can put out the Shino end of the full bobbin 1a and make a Shino joint, and after the Shino joint ends, remove the small ball bobbin 1c and replace the Shino
Since the lifting amount of the lead-out brush and the lead-out nozzle must be increased, the Shino exchange 50 becomes large.

Further, in the present embodiment, the case where the full bobbin 1a is hung on the spare bobbin hanger 24 of the bobbin carriage 17 mounted on the spare rail 15 has been described. When holding in a mounted state, for example, a full bobbin with a full bobbin exchange head 52 and a small bobbin exchange head 55 as shown in Japanese Patent No. 702337, in which a peg of the small bobbin exchange head 55 is changed from a vertical direction to a horizontal direction, By attaching to the small bobbin exchange heads 52 and 55, the exchange with the full bobbin held in the mounted state can be easily performed.

Incidentally, in the above-mentioned embodiment, the case where six pieces are replaced by each other is illustrated, but it goes without saying that it may be carried out in a unit of plural pieces such as four pieces and eight pieces which are practically preferable.

〔The invention's effect〕

In the present invention, the small bobbin exchange head is removed at the exchange work position, the plurality of small bobbin and the plurality of full bobbins are exchanged by mounting with the full bobbin exchange head, and the Shino ends of the plurality of full bobbins are extended by the ejection member. At the same time, the Shinotsu head superimposes on the corresponding Shino at the same time, and the Shinobu of those full bobbins are hooked on the roving guide by the Shino hanging member. The work positions can be combined at almost the same time, and as a result, Shino exchange and Shinotsugi and Shinakake work can be performed efficiently in cooperation, and the work space for a series of Shino replacement can be reduced, and when mechanizing. The mechanism can be greatly simplified and the size can be reduced. Also, since Shino exchange, Shinotsugi, and Shino-Kake are performed at almost the same time, sain drop and Shino entanglement during Shino changing can be prevented, and Shino changing work can be performed reliably. Also, since a series of Shino changing operations, Shino Tsugi and Shino Kake, are performed simultaneously on multiple bobbins, the Shino changing operation per spinning machine can be speeded up and the overall Shino changing time can be shortened. .

Further, as an effect of the invention in the embodiment of the present invention, by connecting a plurality of full bobbins with the full bobbin exchanging head removed from the bobbin holding position, it is easy to loosen the full bobbin in the continuous joining operation. Can be controlled to prevent shining mistakes, and multiple small bobbins can be completely wound by winding the small bobbin hanging on the roving guide by removing the small bobbin from the bobbin hanger with the small bobbin exchange head. After picking up, the full bobbin can be hooked with the hook member, and the hook can be made simple to prevent mistakes.
