Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a method for connecting a spinning machine in a spinning machine. To be more specific, when the Shino-maki bobbin hung on a bobbin hanger and spun in a spinning machine becomes a small ball, the small bobbin Shino is replaced with the small bobbin Shino of the full bobbin Shino Regarding the method.

[Conventional technology and its problems]

When the Shinobaki bobbin hanging on the bobbin hanger of the spinning machine becomes empty or becomes a small bobbin, the Shinobaki bobbin is replaced with a full bobbin, and the full bobbin Shino is replaced with a small bobbin Shino. It is necessary to splice or insert the full bobbin into the drafting section of the spinning machine again.

However, as is well known, the shinobo of the shinomaki bobbin is fluffy because it is given a slight twist, so the shinobi is broken by only lightly pulling. Since it is difficult to mechanically splice such a weak Shino, a Shino exchange running on the base of a spinning machine as disclosed in, for example, Japanese Patent Laid-Open No. 60717/1974 has been used to remove the spinning machine. Only the work of exchanging the small bobbin mounted on the bobbin hanger and the full bobbin mounted on the bobbin hanger of the spare rail was automated, and the shinotsuji work had to be done manually.

[Means for solving problems]

Therefore, the present invention is intended to provide a method for connecting a spinning machine, which has been made impossible in the past, so as to automate the processing, and a Shinobaki bobbin suspended on a bobbin hanger is a small ball. When it becomes, first open the full bobbin to be replaced with the small bobbin, grasp the shino end, hold the shino end in the shino guide groove, guide it upwards to the trumpet, and hold it in the shino guide groove. The Shinano end of the full bobbin is released from the small bobbin along with the running Shino that is supplied to the trumpet, and then the Shino of the full bobbin is released. By moving Shino while the bobbin is running, it moves in the Shino guide groove, and by that movement, the Shino end of the full bobbin is supplied to the trumpet,
After that, the shino of the small bobbin is cut, and the shino of the full bobbin is connected to the shin of the small bobbin while running.

Drive means for moving the respective members in a predetermined cycle are provided. Figure 1 to 18 below
The respective constituent elements will be described with reference to the drawings.

First, the full bobbin replacement head 52 will be described. On the change lever 71 of the full bobbin exchange head 52, six full bobbin exchange head pegs 53 are rotatably arranged (FIG. 11). In order to move the full bobbin 1a at the position shown in FIG. 3 to the position of the small bobbin 1c using the peg 53, it is necessary to move the peg 53 up and down and back and forth. As shown in FIG. 5, the change bar 71 in which six pegs 53 are arranged is connected to the full bobbin exchange head lifting mechanism shown in FIG. 1 through a link mechanism having an inner link 75 and an outer link 76 as main parts. It is arranged above the lifting body 37 of 31. The elevator 37 has two chains 36a, which are parallel to each other in the vertical direction,
36b are connected, and this chain 36a, 36b is connected to Shino exchange.
Motor for lifting and lowering mechanism of full bobbin exchange head arranged in 50
By using 32 to move up and down,
Is moved up and down. 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 in the full bobbin exchange head 52 and its rotating mechanism 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.

Turn counterclockwise with 0. This pivoting movement is a connecting link 1
50 continues from the position shown in FIG. 8 to an opposite position symmetrical with respect to the vertical line passing through the pin 149, so that the chin 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 abuts on the lower end of the elongated hole 150a,
After that, the pin 149 is pulled to the right by the connecting link 150 to rotate the inner link 146 about the shaft 145, and accordingly, the horizontal joint Shino head 60 is spun along the locus indicated by 154. We will proceed toward Shino R from Kodama Bobbin 1c that is out.

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 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 is the main body
A motor 217 with a reduction gear fixed to 51, a worm 218 rotated by the motor 217, an arm 155 having a worm oil meshing with the worm 218, and swinging around a pin 155a, By swinging the arm 155, the rod 145 is selectively moved 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. 14th
The Shinoya joint head 60 shown in FIGS. 15 and 16 has a Shinano joint head main body 171 and a main body 171 in which a Shino guide groove 173 is formed at the tip thereof.
And a shining lever 174 reciprocally movable across the shining guide groove 173 in a plane parallel to the upper surface. The main body 171 is fixed to a Shino joint head support bar 148 having a U-shaped cross section. Shino grasping lever 174 is a pivot pin fixed to the main body 171.
A pin 179 is rotatably supported near the center of the pin 178, while a pin 179 is provided at the rear end of the pin 179. 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. Nip pieces 176 and 177 having shining gripping surfaces 176a and 177a opposed to shining gripping surfaces 175a and 175b on both sides of shining gripping portion 175 at the tip of shining lever 174 respectively have nip pieces 176 and 177 at the upper side surface of main body 171 at both sides of shining guide groove 173. It is fixedly installed in.
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 through the conduit 184 is guided to one side of the shino guide opening 172. An opening of a nozzle 183 for ejecting downward of the groove 173 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 is moved to the right and the shining surface 175a of the shining lever 174 and the nip piece 1 are moved.
A small bobbin Shino (not shown) between the Shino gripping surface 177a of the 77
The position of the shino grasping lever 174 in the standby state for grasping and the guide of the full bobbin into the shino guide groove 173 is shown. The Shinobu extending between the full bobbin 1c and the outlet nozzle 62 in the state where the Shinotsuji head 60 is positioned at the vertical position of the Shinojo head 60 described with reference to FIG. 8 passes through the Shino guide opening 172 and the Shino guide groove 173.
Then, the shino gripping lever 174 is rotated to the right as shown in FIG.
While being gripped by the 74 and the nip piece 176, and then 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 brush at the downstream side of the gripping point. As a result, the tip end of the brush-shaped boss that will be overlapped with the boss of the small bobbin being spun is positioned in the guide groove 173. At this time, 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 brush tip shape of the tip of the shino can be made uniform. In this state, the Shinotsu head 60 is brought closer to Shino R of the small bobbin being spun along the locus shown by the solid line 154 in FIG. / 2 Spindle pitch laterally moved, so that 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 the Shino R of the small bobbin. Is polymerized into. That is, the Shino end of the full bobbin 1a is fitted to the Shino R of the small bobbin 1c in the guide groove 173. Next, as shown in FIG. 14 (B), the shino grasping portion 175 of the shino grasping lever 174 is rotated to the left and moved to the neutral position, whereby the shino end of the full bobbin is released from the grasped state, and the full bobbin is released. The bobbin Shinohana is
It is guided toward the trumpet 6 by the part of Shino R that is continuously drawn from the small ball bobbin toward the trumpet. That is, the bobbin full of the moving small bobbin 1c
Since the Shino end of 1a is pressed in the guide groove 173, the Shino R moving moves the Shino end of the full bobbin. Therefore, the full end of the bobbin is 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, the Shino gripping unit 175 is rotated to the left as much as possible as shown in FIG. Left grip surface 175a of Shino grip 175
And the grip surface 177a of the left nip piece 177 is used to grip the small bobbin Shino R. 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, there are four plungers 189 of the operating bar sliding solenoid 185 fixed to the Shinojo head supporting bar 148, the L-shaped member 188, the pin 200 and the hole.
Each is connected via 186. Each solenoid 185
The plunger 189 can move freely when it is not energized, and the plunger 189 is immersed when it is energized. The pin 200 has an actuating bar 18 through a hole 186.
Engage with 2 to transmit the motion of the plunger to actuation 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), the solenoid 185b is energized (shown in FIG. 17 (C)). ON) and retract the plunger 189 to pin 200
b is moved in the direction of arrow B, and the operating bar 182 is moved 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, 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 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. The shining plate actuating mechanism uses the shining operation cam 68 of the operating mechanism 65 shown in FIG.
The movement of the link mechanism in which 101 and the inner link 102 are merged gives the Shino hanging 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 downward movement of the rod 95 for operating the hanging plate, and its movement is opposite to that of the sector 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. Outer link 1
The lower end of 01 is rotatably pivotally attached to a pin 114a implanted in the connecting link 107 and a pin 115a implanted in 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 so that the inner link 102
The lower end of is connected to the connecting link 107 by the pin 113. The pinion 114a planted in the connecting link 107 is wedge-fitted with the small gear 114, and the pin 115a planted in the support lever 108 is wedge-fitted with the small gear 115, and the small gears 114 and 115 are meshed 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. With this configuration, the outer link 101 and the inner link 102 are rotated with the counterclockwise rotation of the sector gear 105.
Both rotate counterclockwise and approach the swinging end of the outer link 101, and the connecting link 107 uses the pin 114a as a fulcrum because of the connecting length of the outer link 101, the inner link 102, and the connecting link 107. It is turned counterclockwise and the gear 114
Since the small gear 115 meshing with is rotated clockwise, the tip of the shining plate 58 moves as shown by a locus 116 in FIG. 9, and when it reaches the swing end of the outer link 101, the roving guide 2 moves. At the upper part, the Shino hanging plate 58 is tilted toward the machine base to guide the Shinobu of 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 used to hang the shin of the full bobbin 1a on the claw portion 2b of the roving guide 2 shown in FIG. 18, for example.
To move it by 20 mm, it is moved by the horizontal hanging plate horizontal moving mechanism 59 shown in FIG. The horizontal hanging plate moving mechanism 59 is a motor 117 with a reducer fixed to the main body 51.
A worm 118 that is rotated by a motor 117 through a gear 117a and a worm wheel that meshes with the worm 118 at one end, and swings selectively around the pin 119a to the right or left in FIG. And an arm 119 for laterally moving the shaft 112 of the lever hanging plate operating mechanism. As shown in FIG. 9, the lateral movement of the shaft 112 causes the lateral movement of the inner link 102 through the outer link 101 and the connecting lick 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.

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 are well known, 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 hangers 19 in the front row of the creel of the spinning machine are advanced as the spinning progresses.
When the bobbin hung on is the small bobbin 1c and the bobbin hung on the bobbin hanger 20 in the rear row is the middle bobbin 1b, the guide roller 29 of the Shino exchange 50 is placed on the guide rail 28 of the spinning machine. Place the Shino exchange 50 on 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 shinko replacement (Fig. 19 (1)).
In this state, as shown in FIG. 19 (2), the full bobbin 1a hung on the bobbin hanger 24 of the spare rail 15
The full bobbin exchange head 52 corresponding to the position immediately below is lifted by the elevating mechanism 31, and the peg 53 of the full 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 descends and returns to the original position shown in FIG. 19 (1), and as the full bobbin exchange head 52 descends, the outlet nozzle 62 is operated by the outlet nozzle operating mechanism. Ascended and descended full bobbin 1a
The outlet nozzle 62 is stopped at a position where the suction port of the outlet nozzle 62 corresponds to the height position of the tip of the outlet nozzle (Fig. 19 (3)). Next, the motor 54 of the peg rotation mechanism built in 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 dispensing nozzle 62 is wound in advance. Rotate 180 ° in the take-up direction, and move the ends of these full bobbins to the ejection nozzle 62 side. Then motor 5
4, 5 are 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 ends of the corresponding full bobbins and discharge the shino of the full bobbin 1a (Fig. 19 (4)). While continuing the rotation of the full bobbin 1a and the suction of the outlet nozzle 62, the outlet nozzle 62 descends and returns to its original position, at which time the exposed shino enters the shino guide groove 173 of the shinotsugu head 60 (Fig. 19). (5)). The solenoid 185c of the Shinobu head 60 is energized, and the Shino grip lever 174 operates to operate the Shin grip section 175 and the nip piece 17.
The full bobbin Shino is held between 6 pieces, and at the same time, the Shino joint head, which was vertically downward, is moved to the horizontal horizontal state by the Shino joint head operating mechanism, and at that time, the Shin bobbin 1a Shina is the tip of the outlet nozzle 62. The comb attached inside is caught and cut between the grip point of the Shinobu head 60 and the outlet nozzle 62 to form a Shino end (Fig. 19 (6)). Next, while holding the full bobbin with the Shino end formed, Shinotsu head 60
Moves forward toward the drafting unit 5 of the spinning machine by the Shinotsu head operating mechanism. Shinotsu head 60 stops moving forward while moving forward, and trumpet 6 in which Shino of Kodama bobbin is introduced
To the side (the right side in FIG. 4) by a lateral movement mechanism 61 of the Shinotsugi head for a 1/2 spindle pitch, and the longitudinal direction of the spinning machine corresponding to the trumpet 6 upstream of the drafting section 5 of the spinning machine. After taking the position, the forward movement is resumed until the Shino end of the full bobbin reaches the upper part of the trumpet 6. 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. At the same time, in order to keep the slack of the Shino that has been unwound, the Shino hanging plate 58 is slightly raised by the Shino hanging plate operating mechanism. After the Shinotsu head 60 stops moving forward, the Shinotsu head 60
Energize solenoids 185a and 185b of shino, the Shino gripping lever turns to the neutral position to release the Shino grip of the full bobbin, and the released Shino of full bobbin 1a is guided to Shino of the small bobbin being spun. After being inserted into the trumpet 6 together with Shino, the Shino end of the full bobbin 1a is gripped by the back roller 5a of the drafting unit 5, then the solenoid 185b of the Shino joint head 60 is energized, and the Shino gripping lever 174
Rotates further to grip the Shino of the small bobbin between the Shino gripping portion 175 and the nip piece 177. The small bobbin Shino is held by the Shinotsu head 60, so it is drafted between the back roller and cut (Fig. 19 (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 rotated counterclockwise by the peg rotation mechanism of the full bobbin replacement head 52 to unwind the shin, and the shin is prevented from being cut by the rising of the full bobbin 1a. Holds the slack of Shino of the full bobbin 1a that has been lifted up to near the roping guide 2 and unwound. During this time, the solenoid of Shinotsu Head 60
185a and 185d 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 Shinbo of the full bobbin 1a is removed from the Shino joint head 60. The Shinotsu head 60 moves backward and stops (Fig. 19 (8)). The small ball bobbin exchange head 55 advances 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 (Fig. 19 (9)). The small ball bobbin exchange head 55 on which the small ball bobbin is placed descends (Fig. 19 (10)),
Retreat and return to the original position. (Fig. 19 (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. 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 changing head 52 to wind up the shin, and the slack of the shin caused by the lowering of the full bobbin changing head 52 is properly maintained. 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 through the roving guide 2 installed on 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. 19 (12)). The Shinotsu head 60 that has finished retreating is returned from the substantially horizontal state to the vertical state (Fig. 19 (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 in the clockwise direction by an appropriate amount by the peg rotation mechanism of the full bobbin exchange head 52 to properly maintain the slack of the shin caused by the forward movement / ascent of the full bobbin exchange head 52. After that, the small bobbin changing head 55 moves forward to just below the spare bobbin hanger 24 on the spare rail 15 and rises to mount the small bobbin on the bobbin hanger 24. Shino hanging plate
58 descends and moves laterally in the middle to return to its original position (Fig. 19 (1
Four)). The small bobbin exchange head 55 descends, retreats, and returns to its original position, and the full bobbin exchange head 52 descends, retracts, and returns to its original position (Fig. 19 (15)).

Thus, one cycle of Shino exchange work is completed
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 50 may perform Shino exchange and Shino joining work in the following procedure. After raising the full bobbin exchange head 52 and fitting the full bobbin 1a to the peg 53 (Fig. 19 (2)), the small bobbin exchange head 55 is moved forward and raised 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. 19 (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 unwind and rotate 1c. However, according to this method, the operation of retracting the full bobbin 1a upward in order to avoid interference between both bobbins when the full bobbin 1a and the small bobbin 1c are exchanged after the completion of the connection in the embodiment of FIG. 22 (FIG. 19) (Operation of full bobbin 1a of (9) to (11))
Can be omitted.

In the present embodiment, the Shinotsu head 60 is provided so as to correspond to the center of the full bobbin 1a. Therefore, while the Shinotsu head 60 is moving forward, it is laterally moved by 1/2 spindle pitch to correspond to the trumpet 6. However, the horizontal movement of this 1/2 spindle pitch is first to the left on the same spinning machine, and then to the right on the next shino exchange. 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. Shinobetsu head 60 and outlet nozzle 62 are designed to be able to move laterally by the spindle pitch, and a full bobbin is provided at a position corresponding to trumpet 6.
If the Shino end of 1a 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. And, this brush and tap nozzle 62 for tapping

The Shinobashi exchange machine 50 is a large-sized machine because the small bobbin 1c can be removed and the Shino joint changed after the Shino joint is completed. Becomes Also,
In the above embodiment, after the splicing, the slats of the small bobbin being spun are gripped by the sling grip lever 174 and the nip piece 177, and the slats are pulled and cut by the spinning of the back roller 5a. Even if the lower surface of the lever 174 and the upper surface of the nip piece 177 of the above embodiment are configured to slide on each other, and the lower surface of the grasping lever 174 and the upper surface of the nip piece are cut like a pair of scissors to deviate from the present invention. is not. The reciprocating movement of the shino gripping lever 174 across the shino guide groove 173 may be performed in parallel by fixing the shino gripping lever 174 to the operating bar 182. Also, the Shino gripping lever 17 of multiple Shinotsu heads 60
When 4 are operated by the same operating bar 182, it is preferable to interpose a spring between the shining lever 174 and the operating bar 182 so that the shining of each shinko head 60 is surely performed.

〔The invention's effect〕

As described above, in the present invention, the Shino end protruding from the full bobbin is grasped, and the Shino end is held in the Shino guide groove and guided to the upper side of the trumpet, and is held in the Shino guide groove. After superimposing the end along the moving Shinobu bobbin and superimposing it, release the grip on the full bobbin Shino and move the Shinbo end of the full bobbin with the small Shinbobbin moving Shino, Since the full bobbin's Shino end is supplied to the trumpet, the full bobbin's Shino end can be straightened by the Shino while the small ball bobbin is running to supply it to the trumpet, eliminating bending of the Shino end at the time of Shino splicing. And good Shinotsugi can be performed. Also, since the Shinobashi end of the full bobbin is moved by the Shino while the small bobbin is running to supply it to the trumpet, even if the diameter of the trumpet is small, it is possible to reliably perform Shino splicing by moving together. The operation for splicing consists of a simple and simple operation such as pressing the shining end of the full bobbin in the shining guide groove against the running shining end of the small bobbin as described above, and releasing the gripping of the shining end. Successive mechanization can be easily realized.
