2. Description of the Related Art When the Shinomaki bobbin of the creel of a spinning machine becomes a small bobbin or an empty bobbin, it must be replaced with a full Shinomaki bobbin. The Mitsuru Shinomaki bobbin weighed nearly 3 kg, and it was hard work for workers to suspend it from a creel at a high location. Therefore, in order to automate such Shino replacement work, ■ When the Shinomaki bobbin in the front row becomes a small bobbin, it is possible to replace multiple (for example, 6) front row small bobbins and multiple full bobbins on the spare rail. Shino exchange is carried out together with Shino Tsugu, and before the next Shino exchange, the replaced full bobbin in the front row and the medium bobbin in the rear row that is currently being spun are exchanged by a Shino shunter (Japanese Patent Laid-Open No. 1983-1999). 53425), ■In order to replace the pair of small bobbins on the front and rear of the creel (hereinafter referred to as the pair of small bobbins on the front and back) and the two full bobbins on the spare rail every other row along the longitudinal direction of the machine, a Shino exchange machine is used. An empty winding transfer device and a full winding transfer device each having a pair of pegs in the main body are arranged side by side, and the longitudinal pitch between the four pegs is made to match the bobbin pitch of the creel, and inside the main body of the Shino exchanger, The empty and full winding transfer device requires a work space corresponding to four creel bobbins in the longitudinal direction of the machine (Japanese Patent Laid-Open No. 61
-119728), or a combination of this with Shinotsugu (Japanese Unexamined Patent Publication No. 127368/1999).

[Problem to be Solved by the Invention] According to the above-mentioned conventional technique (2), since two or more pieces of wire can be exchanged at the same time, the time required for changing the wires per spinning machine is much longer than in (2). Although it has the advantage of being able to be made shorter, it has the practical problem of being limited to spinning machines equipped with a Shino shunter, as mentioned above. Also, according to ■, there is an advantage that the shinobi shunter required in the above-mentioned ■ is not required, but since two shunters are replaced in sequence, the shinobi replacement time for one spinning machine is longer than that in the above-mentioned ■, which is not practical. . In addition, in order to exchange the front and rear pairs of small bobbins, the empty and full bobbin transfer device requires work space corresponding to the four creel bobbins in the longitudinal direction of the machine, so in order to shorten the bobbin exchange time. Even if multiple sets of the empty and full bobbin transfer devices are mounted on the main body of the Shino exchanger and multiple pairs of front and rear bobbins are exchanged at the same time, the working space overlaps and multiple pairs of full and full bobbins are exchanged simultaneously.
It was not possible to maintain the positional relationship between the small bobbin and the corresponding transfer devices, and in the end, method
I can only handle weights.

In order to solve these problems, the present applicant has already proposed a system in which the small bobbins of a spinning creel can be exchanged in front and rear pairs, and moreover, in multiple pairs at the same time (Japanese Patent Application No. 2-300506). ). The present invention relates to an improvement of this application, and includes a method for replacing the wires that can more stably and reliably perform the replacement of wires by lowering the height of the spare rail to which the wire exchanger is applied, and a method for implementing the method. The purpose is to provide a suitable Shino exchanger.

[0005]

Means for Solving the Problems To achieve the above object, the applicant proposes two methods and an apparatus. That is, the first method is to place the left and right pairs of full bobbins corresponding to the front and rear pair of small bobbins to be replaced on the creel from the bobbin hanger of the spare rail, directly below the spare rail, and with the small bobbin pair to be replaced. Lower the bobbin onto the Shino exchanger so that it faces the next pair of medium bobbins, move the full bobbin on the Shino exchanger on the side opposite to the pair of small bobbins to the rear side of the other, and remove the pair of small bobbins to be replaced. Remove the creel from the bobbin hanger and take it down as a front and rear pair next to the full bobbin pair on the Shino exchanger, and remove the front small bobbin located at the left and right ends of the Shino exchanger from directly below the spare rail. The bobbin on the Shino exchanger is moved one pitch in the left and right direction so that the full bobbin pair faces the bobbin hanger pair from which the small bobbin has been taken out, and the full bobbin pair is inserted into the opposed bobbin hanger pair. At the same time as returning the upper bobbin to its original position, the small bobbin in the retracted position is returned to the front side of the front and rear pair, and the rear side of the small bobbin of this front and rear pair is moved and rearranged into left and right pairs, and this small bobbin pair is The feature is that a full bobbin is inserted into the left and right bobbin hangers of the removed spare rail, and these operations are repeated sequentially from one end of the machine base to the other end.

[0006] In addition, a second method is to carry out the Shino exchange by holding the small bobbin deposited in the shelter position at the time of the first Shino exchange on the Shino exchange machine until the last Shino exchange in the first method, The feature is that the small bobbin in the retracted position is returned to the spare rail at the time of the final replacement.

[0007] In addition, as a Shino exchange machine suitable for carrying out these methods, the main body of the Shino exchange machine that runs and stops along the spinning machine is equipped with spare left and right full bobbins corresponding to the front and rear small bobbins to be exchanged. A full bobbin supply device that unloads the front and rear bobbins from the rail onto the Shino exchange machine directly below it, arranges them into front and rear pairs corresponding to the front and rear bobbins to be replaced, and inserts them into the front and rear air bobbin hangers of the creel, and the front and rear pair small bobbins to be replaced. An empty bobbin removal device that takes out the bobbins next to the front and rear full bobbins on the Shino exchange machine, rearranges them into left and right pairs that correspond to the left and right air bobbin hangers on the spare rail, and inserts them into the spare rail, and an empty bobbin removal device that takes out the front and rear bobbins on the Shino exchange machine. The present invention is characterized by being equipped with a bobbin storage device which can temporarily move the front small bobbin located at the left-right end of the main body to a retracted position out of the position directly below the spare rail.

[0008]

[Operation] According to the first method, the full bobbins of the left and right pairs taken down directly below the spare rail are made into front and rear pairs, and the small bobbins of the front and rear pairs are taken out next to them as front and rear pairs, and the left and right ends of the Shino exchanger are Place the front small bobbin in the evacuation position, move the bobbin on the Shino changer to the left and right by one pitch of the creel, place the front and rear pair of full bobbins opposite the front and rear pair of empty bobbin hangers on the creel, and then insert and retract them. Return the small bobbins in the original position to make the front and rear pairs of small bobbins into left and right pairs, and at the same time shift the bobbins on the Shino exchanger by one pitch in the opposite direction to the above and suspend them from the spare rail after removing the full bobbin. As a result, the work space required in the longitudinal direction of the machine base to replace the front and rear pairs of small bobbins corresponds to two bobbins on the main body of the Shino exchanger, and even if multiple pairs of front and rear pairs of small bobbins are replaced at the same time, Adjacent work spaces do not overlap.

In addition, in the second method, unlike the first method, the small bobbin in the sheltered position is not returned to its original position each time the shinobi is replaced, so there is no subsequent one-pitch movement, and the number of stops of the shinobi exchanger is greatly reduced. . In these first and second methods, the front small bobbin at the left and right ends of the Shino exchanger is placed in the evacuation position from directly under the spare rail, so when the Shino exchanger moves one pitch before inserting a full bobbin, the Shino exchanger The upper bobbin and the spare rail bobbin do not interfere.

Furthermore, in the device of the present invention, the deposit operation of the above method is performed by
Execute with bobbin deposit device.

Both ends of the roving guide 9 are formed into locking portions 9a curved toward the center. The roving guide 9 is the support bracket 4
It is suspended by a spring between the holes 1 and 2b, and when a full bobbin FB enters, it is pushed away by the full bobbin FB and escapes to the side, and returns to its original position after the full bobbin FB passes. As shown in FIG. 24, before being hung from the bobbin hanger 7, the Shinomaki bobbins 10F and 10B in the rear row start spinning by hanging the full bobbin FB and the medium bobbin MB alternately in the left and right direction, and each bobbin The two front and rear windings (hereinafter referred to as front and rear pair P1) have the same winding diameter.

Support bracket 4 at the upper end of creel pillar 3
At the tip a, a spare rail 11 having a substantially rectangular cross-section and opening downward extends along the left-right direction, and is located above and in front of the creel 2. A bobbin carriage 13 supporting the same number of bobbin hangers 12 as the bobbin hangers 7 in the front row of the creel 2 in a row in the left-right direction with the left-right pitch A2 is suspended from the spare rail 11 so as to be movable. A full bobbin FB is suspended from each bobbin hanger 12 of the bobbin carriage 13 prior to the thread exchange, and the bobbin carriage 13 is stopped so that each full bobbin FB faces the thread-wound bobbin being spun on the creel 2.

Next, the Shino switch 20 will be explained. In this embodiment, the Shino exchange is accompanied by a Shino connection operation. In FIG. 1, the Shino exchanger 20 includes a wheel 22 at the lower part of the main body 21 and a guide roller 23 guided by the guide rail 1a of the spinning frame 1, and includes a scroll cam rotated by a running motor (not shown) and the guide rail 1a as is well known. The spinning machine 1 travels along the spinning machine 1 by engaging with a guide pin projecting laterally, and stops at a predetermined shirring change work position.

[0014] The main body 21 has a small bobbin SB of front and rear pairs P1.

Small bobbin S
The present invention includes a bobbin depositing device 160 for temporarily depositing the bobbin B to a shelter position S6 (FIG. 26) which is located outside directly under the spare rail 11, and drive means for operating these devices.

First, the peg units 30A and 30B will be explained. The six peg units 30A and 30B are every other peg unit 30A for empty bobbins and peg unit 30 for full bobbins from the side closest to the bobbin storage device 160.
It is B. In the full bobbin peg unit 30B,
As shown in FIGS. 5 and 7, the slide body 31 is constructed by connecting the left and right side plates 31a, 31b with a front block 31c, an intermediate block 31d, and a rear block 31e. As shown in FIG. 3, a front peg 3 is mounted on the front block 31c.
2 is rotatably supported, and is rotated via a gear train 34 by a forward/reverse motor 33. As shown in FIG. 5, the front block 31c and the intermediate block 31d are connected by two guide rods 35 in the front and rear direction. A support body 36 is guided by the guide rod 35 so as to be slidable by a predetermined amount in the front-back direction. The rear lower surface of the support body 36 and the front block 31c are connected by a cylinder 44. The front portion of the support body 36 is a mounting portion 36a that projects upward.

As shown in FIG. 4, a fixed gear 37 having an upwardly oriented support shaft 37a is integrally fixed to the mounting portion 36a. The base of a swing arm 38 is horizontally rotatably supported on the support shaft 37a, and a gear 40 rotated by a swing motor 39 attached to the upper surface of the arm meshes with the fixed gear 37. A rear peg 41, which together with the front peg 32 constitutes a pair of pegs, is rotatably supported on the top surface of the tip of the swing arm 38 at the same height as the front peg 32. It is configured to rotate via a gear train 43 by a forward/reverse motor 42 . Before these,
By appropriately rotating the rear pegs 32 and 41 forward and backward, the thread R2 unwound from the full bobbin FB on the pegs 32 and 41 is brought into an appropriate slack state during the thread exchange operation described later.

The base of this swing arm 38 and the rear peg 41
The distance (turning radius) and the amount of movement in the longitudinal direction of the support body 36 are such that the rear peg 41 is aligned in the longitudinal direction with respect to the front peg 32 when the support body 36 is at the rearward end where it contacts the intermediate block 31d. At this time, the rear peg 41 is at the original position S1 (FIG. 30 (3)) where the distance from the front peg 32 is the longitudinal pitch A3 of the bobbin hanger 7 of the creel 2, and from that state the swing arm 38 swings at a certain angle. When the support body 36 is at the forward end position in contact with the front block 31C, the rear peg 41 is aligned with the left and right pitch A2 of the bobbin hanger 7 of the creel 2 in the left and right direction of the front peg 32 at a displacement position S2 ( It is set to the amount as shown in Figure 30 (1)),
Moreover, as shown in FIG. 30(2), when the support body 36 is at the backward end and the swing arm 38 is rotated to bring the rear peg 41 to the original position S1 (or vice versa), the rear peg 41 Even if a full bobbin FB with a large diameter that is extremely close to the left-right pitch A2 is placed on top, it is designed not to interfere with the outer periphery of the adjacent full bobbin FB. In this way, the full bobbin FB is connected to the left and right P.
2 and a mechanism for converting between the front and rear pairs P1 is configured.

Next, the longitudinal movement mechanism of the peg unit 30B will be explained. In each peg unit 30B, a guide rod 47 in the front-rear direction is fixed to the upper surface of a bracket 46 provided on the inner side of both front and rear ends of a base 45 having a U-shaped cross section and opening upward.

The rotation of the pinion 51 causes the slide body 31 to move to the slider 65 via the second rack 49.
moves forward with the amount of movement twice the amount of forward movement of peg unit 3.
In 0B, the front and rear pegs 32 and 41 move back and forth between the positions directly under the two rows of bobbin hangers 7 on the front and rear of the creel 2 from the state in which the rear peg 41 is in the original position S1 in the Shino exchanger 20. ing.

Next, as shown in FIG. 8, in the peg unit 30A for small bobbin, a fixed gear 37 is fixed to the front block 31c instead of a support 36 and its back and forth movement mechanism, and the fixed gear 37, that is, the support shaft Since the swing arm 37a does not move back and forth, the swing radius of the swing arm 38a is set long, and only by the horizontal swing of the swing arm 38a, the rear peg 41 is positioned between the original position S1 and the displaced position S2, and the small bobbin SB is moved. The front and rear pair P1 is converted into a left and right pair P2. Further, the forward and backward movement mechanism of the peg unit 30A is almost the same as that of the peg unit 30B, but the gear train 233 that drives the third rack 68 includes an intermediate gear 236. As shown in FIGS. 3, 9, and 10, the right side plate 31b of the slide body 31 of the peg unit 30A includes a front and rear bar 241 that extends over the entire length of the side plate, and a front and rear bar 241 that bends diagonally forward and upward from its front end and extends forward of the upper end of the front peg 32. Crossing, pace 4
A Shino handling guide 240 consisting of a guide portion 242 raised upward above the left side plate of No. 5 is integrally fixed. This Shino handling guide 240 is connected to the Shino R2 in front of the peg unit 30A as shown in FIG.
When 0A moves forward, it is moved to the side and the peg unit 30A (
Alternatively, this is to prevent the small bobbin SB above it from interfering with Shino R2.

Next, the elevating device for the peg units 30A and 30B will be explained using FIGS. 11 to 13. Upper and lower brackets 55a and 55b of the main body 21 of the Shino exchanger 20
Six vertical guide rods 56 are vertically arranged between them. As shown in FIG. 11, every other three guide rods 56 are fitted with elevating members 57 for empty bobbins, and the remaining three are fitted with elevating members 58 for full bobbins so as to be able to move up and down. Each of the three elevating members 57, 58 is connected to a connecting plate 57b, 58, respectively.
connected by b. The base 45 is integrally connected to the upper ends of the connecting portions 57a and 58a extending upwardly of each of the elevating members 57 and 58, and the front pegs 32 of the adjacent peg units 30A and 30B are connected with the rear pegs 41 at the original position S1.
The left and right pitches of the rear pegs 41 are made to match the left and right pitch A2 of the bobbin hanger 7 of the creel 2, respectively. Each lifting member 57, 58 is connected to a driving sprocket 60 of a lifting motor 59 provided at the bottom of the main body 21, and a bracket 5 at the top.
The peg units 30A and 30B are connected to the middle of a chain 62 wound between sprockets 61 rotatably supported by the sprocket 5a, and as the chain 62 rotates, the peg units 30A and 30B are placed in the vertical standby position (FIG. 12S3) and in the spare position. Rising end position for attaching and detaching the bobbin to the bobbin hanger 12 of the rail 11 (Fig. 12S4
) so that it can be raised and lowered between Thus, in this embodiment, the empty bobbin peg unit 30A, its front and rear, and lifting devices constitute an empty bobbin removal device, and the full bobbin peg unit 30B, its front and rear, and lifting devices constitute a full bobbin supply device.

Next, the Shinobata drawing device 70 will be explained. 14 and 15, plates 71 are attached to both sides of the main body 21 of the Shino exchanger 20 from the bottom surface of the main body 21 toward the top. A diagonal guide rod 73 extends from the outside of each plate 71 . Left and right guide rod 7

A chain 78 wound between sprockets 77 rotatably supported at the top is connected to each other. At the tips of the left and right slide blocks 74, there is a pipe 7 with one end connected to a suction source.
9 is supported rotatably and movably in the axial direction. One end of a lever 80 is integrally connected to one end of the pipe 79 (left end in FIG. 15). The other end of this lever 80 is shown in FIG.
As shown in the figure, it is divided into two parts, and a cam follower 82 is rotatably supported on each of these two parts 81. These cam followers 82 sandwich a laterally moving plate cam 85 integrally fixed to the left side plate of the main body 21 from both left and right sides. The lateral moving plate cam 85 moves the pipe 7 as the slide block 74 rises.
9 is bent to shift the trumpet pitch A1 in the left-right direction. Three sets of two outlet nozzles 89 are fixed to this pipe 79 and communicated with each other. The left-right pitch of the outlet nozzles 89 in each set is matched with the left-right pitch A1 of the trumpets 14 of the spinning machine 1, and the left-right pitch between each set is set to four times the left-right pitch A1. A cam groove 72 is formed in the lateral movement plate cam 85, and another cam follower 86 provided on the lever 80 perpendicularly to the cam follower 82 is fitted into the cam groove 72. The cam groove 72 is formed so that as the slide block 74 rises, the outlet nozzle 89 rises along a trajectory that does not interfere with the shading head 100, which will be described later. Therefore, as the slide block 74 moves up and down, the outlet nozzle 89 moves up and down while being shifted between the standby position S7 and the outlet position S8.

Next, the Shinotsugi head 100 and its operating mechanism will be explained with reference to FIGS. 2, 18, and 19.

Although not shown, it is a well-known single-acting cylinder with a built-in spring inside the cylinder body, and is always biased by the spring so that the piston rod protrudes (the state shown by the solid line). The left and right guide recesses 145a are at an interval equal to the interval A2 between the full bobbins, and are substantially opposed to the openings 8 of the two C-shaped roving guides 9 to be hung.

Next, the bobbin deposit device 16 for the small bobbin SB
0 will be explained. A bobbin depositing device 160 is attached to the main body 21 on the left side of the small bobbin peg unit 30A located on the leftmost side in FIG. In the bobbin depositing device 160, an arm 162 is horizontally rotatably supported on a base 161 fixed to the main body 21, and a gripper 163 is attached to the tip of the arm 162, which opens and closes by operating a built-in cylinder. The arm 162 is horizontally oscillated by a predetermined angle via a gear train 165 by a motor 164 fixed to the base 161, and is connected to the peg unit 30A located on the leftmost side in FIG.
The gripper 163 is configured to swing between a position S5 vertically above the front peg 32 and a retracted position S6 located just below the preliminary rail 11. The height of the bobbin storage device 160 is set to such a height that it passes below the bobbin RB suspended from the spare rail 11.

When the first method of the present invention is implemented with the above configuration, the process is as follows. Fill the front and rear rows of creel 2 with medium bobbins FB and MB every other row in the left and right direction and start spinning. When the medium bobbin MB becomes the small bobbin SB, the Shino exchanger 20 moves to the left along the front of the spinning machine 1 (in the direction of the arrow Y in FIG. 28) and replaces the right end of the small bobbin SB of the three front and rear pairs P1 to be replaced. The column and the peg unit 30A for small bobbin at the right end (lower end in FIG. 28) mounted on the Shino exchanger 20 are stopped facing each other, and each peg unit 30
Each of the front pegs 32 A and 30B is located directly below the full bobbins FB of three adjacent left and right pairs P2 (six pieces) of the spare rail 11 (FIG. 28(a)). At this time, Shinotsugu head 100,
The outlet nozzle 89 faces the trumpet 14 that guides the thread R1 of the small bobbin SB to be spliced, and the thread guide member 145 faces the C-shaped roving guide 9 that guides the thread R1 of the small bobbin SB. are doing. With the support body 36 positioned at the forward end, the three full bobbin peg units 30B are raised from the standby position S3 to the rising end position S4 via the lifting motor 59 and the chain 62, while reaching the rising end position S4. Then, the swing motors 39 of the three full bobbin peg units 30B are operated, and the swing arm 38 is horizontally rocked counterclockwise by the action of the fixed gear 37 and the gear 40, and the rear peg 41 is moved to the displacement position S2. let The creel 2 is attached to the front and rear pegs 32, 41 of the full bobbin peg unit 30B that has been raised in this way, and the three of the spare rails 11 that correspond to the three front and rear pairs of small bobbins SB of P1 to be replaced.
Two full bobbins FB of left and right pairs P2 are placed. The raised peg unit 30B is lowered to the full bobbin unloading position S10 and stopped.

Next, the motor 75 for raising and lowering the outlet nozzle revolves around the chain 78, and the slide block 74 rises diagonally forward and upward, so that the cam follower 82 is guided to the lateral moving plate cam 85, and the cam follower 86 is guided to the cam groove 72, respectively. Then, the outlet nozzle 89 is raised while moving in the left and right direction from the standby position S7 to the outlet position S8.
8, it stops close to the outer periphery of six full bobbins FB. At the outlet position S8, a suction source (not shown) is activated and the outlet nozzle 89 starts suction, and the front and rear pegs 32, 41 on which the full bobbin FB is placed are moved by two forward/reverse motors 42, 3.
3, the paper is slowly rotated in the direction of unwinding the paper, and the outlet nozzle 89 suctions and extracts the paper end. While continuing suction, the outlet nozzle 89 is moved laterally from the outlet position S8 to the standby position S7 below the Shinotsugi head 100 and lowered by an operation opposite to the above. At this time, the full bobbin FB is rotated in the unwinding direction so that no cutting occurs. The tip of the full bobbin FB that has been taken out passes through the front of the tip guide member 145 and is connected to the tip grip lever 103 of the tip joint head 100 and the stopper block 1.
It is held between 06 and 06. At this time, the full bobbin on the rear peg 41 of the swinging arm 38 is moved by the Shino handling guide 240.
is hung on the horizontal portion 242a of the guide portion 242 and guided (FIG. 28(b)).

Next, the head swinging cylinder 114 swings the Shinotsugi head 100 from the hanging state to a substantially horizontal state, and the Shino R2 is moved between the outlet nozzle 89 and the Shinotsugi head 100 by the comb (not shown) in the outlet nozzle 89. ), the cut edge is shaped like a brush tip (Fig. 28(c)).

[0032] Next, the lifting motor 139 of the hanging device 130
When the Shino guide member 145 is slightly raised by the operation, the cam follower 143a is guided by the cam surface 144a, and the Shino guide member 145 moves forward, moving between the two Shino R2 between the Shino joint head 100 and the full bobbin FB. Enter the Shino R, each with two Shino R.
2 are separated from side to side by the slope of the Shino guide member 145, and the intermediate portions thereof are located in the respective guide recesses 145a.

[0033] The Shino guide member 145 is connected to the small bobbin S in the front row.
The swing cylinder 11 of the Shinotsugu head 100 is rotated in the unwinding direction while simultaneously moving the full bobbin FB directly below the bobbin FB.
7 to swing the arm 112 to the forward end position,
Move the Shinotsugu head 100 to the Shinotsugu position S above the trumpet 14.
Position it at 9. In this way, the thread R1 of the small bobbin SB is superimposed on the thread R2 of the full bobbin FB held by the thread joint head 100 in its groove bottom 102b, and the thread gripping lever 103 is brought to the neutral position. Then, Shino R of Man bobbin FB
2 is released from the grip, and is taken from the trumpet 14 to the draft roller 15 together with the small ball bobbin SB R1, and is passed on to the draft roller 15 (FIG. 28(d)).

Next, while maintaining the swing angle of the swing arm 38, the support body 36 is brought into contact with the intermediate block 31d by the action of the cylinder 44, and the full bobbins FB that are lined up directly under the spare rail 11 are moved. Make a zigzag arrangement (Fig. 30 (
1), (2)). The swinging arm 38 is rotated as it is, the rear peg 41 is returned to the original position S1, and the full bobbin FB is set to the front and rear pair P1 (FIG. 30(3)). At this time, the rear peg 41
The full bobbin FB above has a smaller swing radius due to the movement of the support 36 in the front and back direction, so the full bobbin FB
Even if the outer diameter is very close to the left and right bobbin pitch A2 of the creel 2, the arrangement can be changed without interfering with the full bobbin outer circumference on the front peg 32 by appropriately setting the amount of back and forth movement. .

Next, the Shino gripping lever 103 is attached to the small bobbin S.
Grip Shino R1 of B between it and the stopper block 107,
By feeding the grain R1 of the small bobbin SB to the draft roller 15, the grain R1 of the small bobbin SB is cut. Next, the forward and backward movement motor 50 of the small bobbin peg unit 30A is driven to move the small bobbin peg unit 30A forward, and the front and rear pegs 32 and 41 are positioned directly below the small bobbin SB of the front and rear pair P1 to be replaced. (Fig. 28(e)). At this time, the jointed Shino R2 is sorted to the side of the peg unit 30A by the guide portion 242 of the Shino handling guide 240 or the front and rear bars 241.

Next, remove the small bobbin SB of the front and rear pair P1 from the bobbin hanger 7 of the creel 2 by lifting and lowering the small bobbin peg unit 30A directly below the small bobbin SB, and place the small bobbin SB on the front and rear pegs 32 and 41. In this state, the small bobbin SB is rotated in the direction of winding by peg rotation, and the cut R1 of the cut small bobbin SB is wound (Fig. 28 (
f)). The empty bobbin peg unit 30A carrying the small bobbin SB is moved backward and taken out next to the full bobbin FB of the corresponding front-rear pair P1 with the front-rear pair P1 intact (FIG. 24). Slightly raise the peg unit 30A, and
The gripper 163 of the bobbin storage device 160 holds the small bobbin SB on the front side of the peg unit 30A located at the left and right ends of the peg unit 30A.
In this state, lower the peg unit 30A to the standby position S3, pull out the small bobbin SB from the front peg 32, and deposit it into the standby position S6 by the arm 162 (Fig. 2
9(a)).

At the same time, the Shino joint head 100 is returned to the standby position vertically, and the Shino guide member 145 is raised and moved slightly forward and above the roving guide 9.
45 is guided into the C-shaped roving guide 9 from the opening 8 of the roving guide 9. Next, the two air cylinders 147 move the Shino guide members 145 closer to each other, and then the Shino guide members 145 are moved backward, and the Shino R2 is hooked inside the locking portion 9a of the roving guide 9 (FIG. 29). b), Figure 25 double-dashed line). Next, the Shino guide member 145 is returned to the standby position, the three full bobbin peg units 30B carrying the full bobbins FB are lowered to the standby position S3, and the entire Shino exchanger 20 is moved rightward to adjust the left-right pitch A2 of the bobbin hanger 7 of the creel 2. The full bobbin FB of each front and rear pair P1 is made to face the empty bobbin hanger 7 from which the small bobbin SB of the creel 2 has been removed (FIG. 29(c)). At this time, since there is no small bobbin SB on the front peg 32 of the peg unit 30A at the right end of the Shino exchanger, there is no small bobbin SB suspended on the spare rail 11 in the previous Shino exchange and any bobbin on the Shino exchanger 20. This also means that the spare rail 11 can be lowered accordingly.

Then, the full bobbin peg unit 30B carrying the full bobbin FB is moved forward and positioned directly below the bobbin hanger 7 of the front and rear pair P1, and then raised and lowered, and the full bobbin FB is placed on the bobbin hanger 7 after removing the small bobbin SB. Insert it (Fig. 29(d)). After that, peg unit 30 for full bobbin
B is moved backward, and the small bobbin SB that was in the standby position S6 is returned to the front peg 32 at the right end by the rotation of the arm 162, the opening/closing operation of the gripper 163, and the lifting of the peg unit 30A, and the creel 2 is moved to the left by moving the Shino exchanger 20 to the left. bobbin hanger 7
The small bobbin SB is moved at the same time by 1 pitch A2.
While raising the small bobbin peg unit 30A carrying the small bobbin SB, the swinging arm 35 is swung to swing the rear peg 41 from the original position S1 to the displaced position S2 with the small bobbin SB mounted thereon. P1 small bobbin SB left and right versus P2
After removing the full bobbin FB, insert it into the bobbin hanger 12 of the spare rail 11 (Fig. 29(
e)). Then, after being in the displacement position S2, the peg 38 is returned to the original position S1, and a series of replacements is completed (FIG. 29(f)
)). Then, the Shino exchanger 20 moves to the left by six pitches of the bobbin hanger 7 of the creel 2, stops, and repeats the above operation.

In the above embodiment, when the front and rear full bobbins are opposed to the front and rear empty bobbin hangers of the spinning creel,
When suspending the small bobbin pair taken out from the spare rail, the main body of the Shino exchanger itself was moved by the left and right pitch. It may be configured to reciprocate in the left-right direction by the left-right pitch A2 while maintaining the pitch A2.

Next, regarding the second method of the present invention, FIGS.
The explanation will be based on 33. In the second method, the Shino exchange operation is different between the first time, the last time, and the intermediate time. First, in the first Shino exchange, after removing the full bobbin FB of 6 spindles from the spare rail 11 in the first method, and inserting the full bobbin FB into the bobbin hanger 7 of the creel 2 (see Fig. 28(a)
29(a) to 29(d)) are the same as the first method. After the full bobbin FB is inserted (FIG. 31(a)), do not return the small bobbin SB in the shelter position S6 onto the front peg 32 at the right end of the Shino exchanger 20, and move the Shino exchanger 20 left or right. Front and rear pegs 3 on the Shino exchanger 20 without moving the pitch
By changing the arrangement of the small bobbins SB on 2 and 41 and inserting them into the bobbin hanger 12 of the spare rail 11, the five small bobbins SB are packed and suspended from the bobbin hanger 12 in the right movement direction of the Shino exchanger 20, Next, the bobbin hanger H to the right of the full bobbin FB to be replaced becomes empty (Fig. 31(b))
).

Next, in the intermediate thread exchange, the work is started in the state shown in FIG. 32(a) with the small bobbin SB held at the standby position S6, and then the steps shown in FIGS. 28(b) to (f) are carried out. executed. Next, take out the small bobbin SB, move it one pitch to the right without retracting the small bobbin SB on the right front peg 32, and make the full bobbin FB face the empty bobbin hanger 7 of the front and rear pair P1 (Fig. 32(b) )). After inserting the full bobbin FB into the creel 2, without returning one pitch to the left, insert the six small bobbins SB on the peg unit 30A into the bobbin hanger 12 of the spare rail 11 by pushing them to the right (Fig. 32 (c)).

In the final Shino exchange, the process is the same as the intermediate part until the full bobbin FB is inserted into the creel 2 (Fig. 33(
a)) After that, the arrangement of the small bobbins SB is changed to the left and right pair P2, and at the same time, they are moved one pitch to the left, and at this position, the six small bobbins SB are suspended from the spare rail 11 (Fig. 33 (
b)). Next, the swing arm 38 of each peg unit 30A
a to the original position S1, move the Shino exchanger 20 one pitch to the right, raise and lower the three peg units 30A, and remove the two small bobbins SB shown by diagonal lines in FIG. 33(c) from the spare rail 11. Take it down again, return the small bobbins SB that had been deposited in this state onto the right front peg 32, and place the three small bobbins SB on the bobbin hanger 12 of the spare rail 11 again.
(Fig. 33(d)).

Also in this second method, when the front and rear full bobbins are moved one pitch to face the front and rear empty bobbin hangers of the creel, the bobbin RB of the spare rail 11 and the Shino exchanger 20
Do not interfere with any bobbins above. In addition, except for the final change of Shino, 1 to the left after inserting the full bobbin into the creel.
Since there is no pitch movement, Shino exchanger 20
The number of times of positioning is greatly reduced, and the time for replacement of wires is shortened.

[0044]

Effects of the Invention As described above, according to the method of the present invention, the left and right
The working space in the longitudinal direction of the machine can be made to correspond to the two bobbins of the creel, and work can be done within an extremely narrow horizontal length. Bobbins can be replaced at the same time. Therefore, compared to the conventional technology (■), the targeted spinning machines are not limited and multiple pairs can be handled at the same time, so even if the small bobbins of the creel are replaced in units of front and rear pairs, the replacement time for one spinning machine is be shortened.

Furthermore, before moving the bobbin by one pitch on the Shino exchange machine, in which the full bobbins, which are arranged as a front and rear pair, are opposed to the bobbin hangers of the front and rear pair of the creel from which the small bobbins have been removed, the movement direction is adjusted on the Shino exchange machine. Since the front small bobbin located at the end is placed in a sheltered position away from directly under the spare rail, the bobbin on the Shino exchanger that was taken out at almost the same height as the creel bobbin when moving one pitch is vertically aligned with the bobbin on the spare rail. Since they do not overlap, the height of the spare rail can be lowered relative to the creel's bobbin hanger. Therefore,
The difference in height between the bobbin of the creel and the bobbin of the spare rail is reduced, the amount of lifting and lowering of the bobbin during the replacement of the wire can be reduced, and the speed of the replacement operation of the wire can be increased. In addition, since the height of the spare rail can be lowered, when the height of the creel bobbin hanger is the same as before, the height of the entire creel is lowered, and as a result, the height of the Shino exchanger can be lowered. The traveling of the Shino exchange machine and the Shino exchange operation can be performed more stably.
