Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supplying Shinobu to a spinning machine, and more specifically, to suspend the Shinoshinomaki for supplying Shino to the draft part in two rows inside and outside, and further to the outside of them. The present invention relates to a Shino feeding method in a spinning machine in which a spare Shino roll for suspension is suspended.

[0002]

2. Description of the Related Art In a spinning machine, a shinomaki is pulled out from a shinomaki suspended on a creel at a high position and is supplied to a lower draft part. In this case, Shino-maki has a considerably larger diameter than the spindle gauge of the spinning machine.
In general, Shino rolls are suspended on creel rails arranged in two rows, inside and outside. Then, as the supply to Shino's draft part progresses, and Shino-maki becomes empty or approaches the sky, it is necessary to replace it with a new Shino-maki. For this exchange
It has long been practiced for an operator to manually carry out Shino-maki carried by a dolly, or for the worker to replace a spare Shino-maki that is previously placed on a creel shelf. Further, in addition to the inner and outer two rows of creel rails, one rail is further provided on the outer side of the creel rail, and a spare shinomaki is hung on this rail, and the worker performs the exchange work as needed. There are also things. According to this type, the spare Shino-Maki rail is of a transport type and can be automatically loaded and unloaded from the roving process or one end of the spinning frame, and is therefore evaluated as a practical one.

By the way, Shino-maki has a large diameter and weighs about 3 kg, which is difficult to handle, and because the creel is in a high position, Shino-maki exchange (Shinomai) is a heavy labor for the worker.

[0004]

From the above, a device for automatically suspending Shino-maki on a hanger of a creel has come to be considered. For example, a spare Shino-maki mounted on a creel shelf is creeled. In order to automatically suspend it on a hanger, Japanese Patent Publication No. 48-22848 published on July 9, 1973
Those described in Japanese Patent Publication are considered. However, in this device, the spare Shino-maki placed in the horizontal state must be changed to the upright state, so the mechanism of the automatic machine is robust and complicated, and the empty Shino-maki is expensive for workers. The drawback is that it must be removed from the creel at the position beforehand. In order to eliminate this defect, May 1, 1983
In Japanese Patent Laid-Open No. 58-81631 published on 7th, as shown in FIG. 17, a spare Shino-Maki 92 suspended from a spare Shino-Maki rail 91 and a Shino-Drum supplied to a draft part 93 are provided. A device for automatically suspending an empty shinomaki on a spare shinomaki rail 91 has been proposed for replacement with a maki.
That is, the empty Shino winding 96 is taken out by the raising and lowering of the take-out arm 95 of the automatic Shino-changing machine 94 and the operation of the forward and backward movement, and the spare Shino-wind rail 9
1, the spare shinomaki 92 of the rail 91 is suspended on a creel instead. However, in this device, various problems are inherent because the simultaneous exchange of the two inner and outer rows of the main Shino winding 96, 97 is not considered. That is, the automatic Shino-changing machine 94 for one row of the spare Shino-maki rails 91
In order to make it easier to work, it is necessary to make a difference in the winding ball diameters of the main Shino winding 96, 97 and to suspend the empty main Shino winding 96 on the outer rail 98 without fail. For that purpose, the Shino-replacement machine 99 for exchanging the inner and outer Shino-maki 96, 97 is equipped, and this Shino-replacement machine 9 is replaced before the spare Shino-maki 92 is exchanged.
9 is an empty Honshinomaki 96 inside and Honshinomaki 97 is a medium ball
Are replaced inside. Therefore, since the machine height becomes high and the spare Shino-wind rail 91 also becomes high accordingly, the vertical movement amount of the take-out arm 95 of the automatic transfer machine 94 also becomes large.

In order to solve such a drawback, the present inventor previously proposed a method of sequentially replacing two inner and outer rows of main Shino-maki with two spare Shino-maki at the same time. In this method, The disadvantage is that the spare Shino-maki must be arranged in two rows.

The present invention has a problem that in the conventional automatic shinomaki method, it is necessary to replace the inner and outer honmaki rolls prior to the replacement work of the spare shinomaki and the main shinomaki, and to perform the replacement work. Due to the fact that it is equipped with a replacement machine, the height of the machine becomes high and maintenance management becomes difficult, and it is difficult to adopt it in the existing factory. This solves the problem that the width becomes large and it is difficult to equip the traveling cleaning body.

[0007]

In order to achieve the above-mentioned object, in the present invention, the main Shino-maki for supplying Shino to the draft part is suspended in two rows inside and outside along the longitudinal direction of the machine base. In the spinning machine, a predetermined amount of difference is provided in the amount of shino winding between the main shino windings adjacent to each other in the longitudinal direction of the machine base so that the shino windings of the respective main windings are supplied to the draft part. Further, it is preferable that the difference of the predetermined amount is half the winding amount of a full ball.

[0008]

According to the present invention, the spare Shino-maki are arranged in one row, and the spinning machine is operated by suspending the bobbin of the medium balls as the main Shino-maki every other row along the longitudinal direction of the spinning machine stand. Spinning is started with a full bobbin suspended as a main Shino-maki in the row. Then, when every second row of Shino-maki rolls are empty or approached, the automatic Shining machine moves from one end to the other end of the spinning frame, and every other row, two empty books inside and outside. Simultaneously remove the Shino-maki, remove two adjacent spare Shino-maki from the spare Shino-maki at the same time, suspend the spare Shino-maki at the position where the main Shino-maki was taken out, and place it at the position where the spare Shino-maki was removed. The work of suspending the Honshinomaki is performed.

When replacing an empty Honoshimaki with a spare Shino-maki, the Honshino-maki suspended on both sides of the empty Hon-shinomaki is a middle ball, and is replaced even when the space between Hon-shinomaki is narrow. Occasionally, the spare Shinomaki will not come into contact with the main Shinanomaki.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. On the creel 1 of the spinning machine, two main and outer rows of main rails 2 and 3 are arranged parallel to the longitudinal direction of the machine base on both left and right sides of the machine base. Honshinomaki rails 2, 3
Each of them is equipped with hangers 4 and 5 at a pitch twice the spindle pitch. Shino drawn from the main shinomaki suspended from the hangers 4 and 5 passes through the shino guide 6 and the guide rod 7 and then the draft part. It is designed to be supplied to 8. A support bracket 9 is further extended outward from the creel 1, and a carrier rail 10 is provided at the tip of the support bracket 9 so as to extend in parallel with the main shinomaki rails 2, 3. Transport rail 10
A magazine 13 including hangers 11 and 12 arranged in a zigzag shape is suspended in the carriage so that the magazine 13 can run. The hangers 11 and 12 arranged in a zigzag form correspond to the spare shinomo row. Each of the hangers 4, 5, 11, and 12 has a structure that can be suspended or removed from the hangers 4, 5, 11, and 12 by moving the Shino-maki up and down. The number of hangers 11 and 12 provided in one magazine 13 is not limited, but as shown in FIG. Hanger 1 with the same pitch as the hangers of Honshinomaki rails 2 and 3.
The Masushino windings F suspended on the Nos. 1 and 12 are arranged in a staggered manner so as not to come into contact with each other.

That is, in recent years, in order to speed up the spinning machine and save energy, the package has been made smaller, and the spindle gauge G has been reduced accordingly. On the other hand, it is desired that the diameter D of the Shino winding be increased in order to extend the replacement cycle. Therefore, in the case of D ≧ 2G, one row of spare Shino-maki has a zigzag shape as in this embodiment.

In addition, since it is not possible to secure the number of main Shino rolls in two rows on one side of the spinning machine with the spare Shino rolls in one row, the Manashino roll F and the Shinanomaki M of medium balls are arranged in every other row. , Spinning is started in a state of being suspended on the carriages 5, and when the spinning is continued and the Shinanomaki M of the middle balls becomes empty, the Shinanomaki of the empty sky is replaced every other row. At this time, the Manashi Shino roll F at the start of spinning becomes the Shinano roll M of the middle ball as shown in FIG. Therefore, even if the space between the bobbin hangers 4 and 5 is narrow, the full Shinano winding F of the spare Shino winding F
It is possible to prevent the Manoshinomaki F from coming into contact with the Honshinomaki winding F when the Honshinomaki rails 2 and 3 are replaced with the empty Shino winding E. This also promotes an increase in the Mitsuno winding diameter.

Next, the automatic transfer device 14 for exchanging the full Shino winding F of the spare Shino winding and the empty Shino winding E of the main Shino winding will be described. The automatic Shino transfer machine 14 takes out the empty Shino roll E from the main Shino roll and suspends it on the hangers 11, 12 of the magazine 13, and the empty Shino roll transfer device 15 and the spare Shino roll F Equipped with a Masushino winding transfer device 16 that suspends the Masushino winding F at the position where the Sky Shino winding E of the main Shino winding is removed, and extends to the front of the spinning machine base. It runs along the spinning machine frame via the guide rollers 18 that engage with the formed guide rails 17.

The automatic transfer machine 14 is connected to a piston rod 19a of a cylinder 19 fixed to the transfer machine 14,
An elevating board 20 is provided which moves up and down while the horizontal state is maintained by the operation of the cylinder 19. Lifting board 20
Uprights are provided on both left and right sides of the upper surface of the rail, and the upper and lower sides of the upright are engaged with rails 22 fixed vertically to the machine frame to regulate the lifting board 20 so as to maintain a horizontal state. Rollers 23, 24 are attached. Further, pulleys 27 for guiding the tape 26, one end of which is connected to the balance weight 25 and the other end of which are connected to the support column 21, are rotatably supported on upper left and right sides of the automatic transfer machine 14. That is, the lifting / lowering substrate 20 is smoothly moved up / down by the operation of the cylinder 19 while maintaining the horizontal state.

On the elevating substrate 20, there is an empty Shino transfer device 1
5 and the Mitsushino winding transfer device 16 are arranged adjacent to each other.
The empty transfer device 15 is horizontally fixed to the upper end of a support shaft 28 rotatably arranged on the elevating board 20, and is rotated by a rotating mechanism. 29, link mechanisms 32 and 33 for moving pegs 30 and 31 that can be fitted into the bottom of a bobbin, which is the core of the Shino winding, between the preliminary Shino winding row and the main Shino winding row, respectively. Has been done. As shown in FIGS. 5 and 6, the turning mechanism of the turning board 29 has a turning lever 35 rotatably supported on a support shaft 34 fixedly mounted on the elevating board 20, and one end thereof. A link 36 having the other end at the tip of the rotating lever 35 rotatably connected to the lower surface of the rotating substrate 29 by pins 36a and 36b, and the base end rotatably fixed on the elevating substrate 20. At the same time, the tip of the piston rod 37a is composed of a cylinder 37 which is pin-connected to substantially the center of the rotary lever 35. That is, the rotation lever 35, the link 36, and the rotation base plate 29 constitute a link mechanism, and the rotation base plate 29 rotates about the support shaft 28 due to the piston rod 37a protruding and retracting due to the operation of the cylinder 37. .

The peg 3 is provided on the upper surface of the rotating substrate 29.
Support bracket 3 corresponding to a fixed link of parallel four-bar links of link mechanisms 32 and 33 for moving 0 and 31 back and forth
8,39 are fixed. Each support bracket 38, 3
9 is a support plate 4 having the pegs 30 and 31 respectively.
Two links 42, 43, 44, 45, whose distal ends are pin-connected to 0, 41, are rotatably supported at their base ends. That is, the support bracket 38, the support plate 40, and the links 42 and 43 constitute one link mechanism 32, and the support bracket 39, the support plate 41, and the link 4 are included.
4, 45 constitute another link mechanism 33. The link 42 is integrally rotatably fixed to a rotary shaft 46 that is rotatably supported by the support bracket 38, and a rotary lever 47 is integrally rotatably connected to the rotary shaft 46. . At the tip of the turning lever 47, the base end is fixed to a column 48 standing on the turning base plate 29 via a bracket, and a piston rod 49a of a cylinder 49 is provided.
Are linked to. Further, since the link mechanism 32 for driving the peg 30 and the link mechanism 33 for driving the peg 31 are interlocked, the link 44 and the link 42 are connected to each other by the connecting member 50.
Are connected by. The connecting position of the connecting member 50 is such that when the peg 30 moves forward to a position corresponding to the inner Honoshimaki rail 2, the peg 31 moves forward with a slight delay and finally corresponds to the outer Honoshimaki rail 3. It is set to stop.

Accordingly, the cylinder 49 is operated and the piston rod 49a is pulled in, whereby the link mechanism 3
2, 33 are rotated in conjunction with each other, and the pegs 30, 31 are moved forward to the positions corresponding to the main rails 2, 3 shown by chain lines in FIG. The links 42 and 43 are formed in a bent shape because they do not contact the draft part 8.

It is to be noted that the intervals c between the lower ends of the bobbins and the pegs 30 and 31 are designed to be the same at the main shino-roll position and the preliminary shino-roll position. Next, Mitsunomaki transfer device 16
Will be described. The Mitsushino winding transfer device 16 is arranged adjacent to the Sorashino winding transfer device 15, and like the Sorashino winding transfer device 15, two pegs that can be fitted into the bottom of the bobbin that is the core of the Shino winding. 51 and 52 can be independently moved back and forth by link mechanisms 53 and 54. Link mechanism 5
Similar to the link mechanisms 32 and 33 of the Kushino Shinko transfer device 15, 3 and 54 are parallel four-bar links, but the support brackets 55 and 56 as fixed links are displaced instead of the rotating substrate 29. Substrate 5 displaced by the mechanism
7 is different from the above-mentioned Sorashino winding transfer device 15 in that it is fixedly installed on the device 7. The link mechanism 53 includes a support bracket 55 as a fixed link, links 58 and 59 whose base ends are rotatably connected to the support bracket 55, and the links 58 and 5.
The peg 51 is connected to the tip of 9 in a horizontal state.
And a support plate 60 having The link mechanism 54 includes a support bracket 56 as a fixed link, two links 61 and 62 whose base ends are rotatably connected to the support bracket 56, and horizontal ends of the links 61 and 62. Support plate 6 connected to the and having a peg 52
3 and 3. A rotary lever 65 is integrally rotatably connected to a rotary shaft 64 to which a link 58 is integrally rotatably fixed, and the rotary lever 65 has a base end at the base 57.
It is connected to a piston rod 67a of a cylinder 67 which is fixed to a column 66 which is erected upright via a bracket. Further, the link 58 and the link 61 are linked by the linking member 68 to link the link mechanism 53 and the link mechanism 54.

Next, the displacement mechanism of the substrate 57 will be described. The substrate 57 is used as the rotating substrate 29 of the Sorashino winding transfer device 15.
Although it is possible to displace it to a predetermined position by rotational movement similarly to the above, since the automatic shinning machine 14 of this embodiment has a narrow machine frame, the center of rotation is outside the machine frame. A displacement mechanism consisting of a four-bar linkage is used. As shown in FIG.
9 and 70 are vertically fixed, the base ends of links 71 and 72 are rotatably supported by both support shafts 69 and 70, and the other ends of both links 71 and 72 are of a base plate 57 that acts as a link. The lower surface is rotatably connected by pins 73 and 74. A base end of the link 71 is connected to a piston rod 75a of a cylinder 75 fixed on the elevating board 20. Therefore, the operation of the cylinder 75 causes the four-bar linkage mechanism to be displaced, so that the substrate 57 forming a part thereof is displaced between predetermined positions.

Next, a description will be given of the changing operation by the automatic changing machine 14. As the spinning progresses, as shown in Fig. 9 (a), every other row of Honoshimaki becomes Ekushinomaki E and the other Honoshimaki is Shino-maki M of the middle ball.
Then, the automatic transfer machine 14 runs from one end of the spinning machine stand, stops at a predetermined transfer position, and enters the state shown in FIG. 9 (a). At this time, the pegs 30 and 31 face the hangers 11 and 12 mounted on the magazine 13, and the pegs 51 and 5 are
The reference numeral 2 is located immediately below the Masushino winding F suspended in the magazine 13. Then, the cylinder 37 of the Shino-maki transfer device 15 is actuated and the piston rod 37a thereof is retracted, and the rotating substrate 2
9 is rotated in the counterclockwise direction in FIG. 9 (a) about the support shaft 28 to be in the state shown in FIG. 9 (b). Next cylinder 49
Is actuated, the piston rod 49a is pulled in, the link mechanisms 32 and 33 are tilted toward the spinning machine base side via the turning lever 47, and the pegs 30 and 31 are suspended on the main Shinobu rails 2 and 3, respectively. Advancing to the position just below the empty Sorashinomaki E,
The state shown in FIG. 10 (a) and FIG. 12 (a) is obtained.
In this state, the cylinder 19 is operated so that the piston rod 19a protrudes by a predetermined amount and is then retracted again. As a result, the elevating board 20 is moved up and down, and along with that, all the pegs 3
As 0, 31, 51, 52 rises all at once and immediately descends, each peg 30, 31, 51, 52 has an empty sky E
And Masushino winding F are inserted and brought into the state shown in FIG. 12 (b). Next, the cylinder 49 is actuated, the piston rod 49a thereof is projected, and the tilted link mechanisms 32 and 33 are returned to their original positions. On the other hand, during this period, the cylinder 75 of the Mitsushino winding transfer device 16 is actuated, the piston rod 75a thereof is projected, the substrate 57 is displaced, and the state shown in FIG. 10 (b) is obtained. Next, the cylinder 67 is actuated, the piston rod 67a is pulled in, the link mechanisms 53 and 54 of the Mitsuno winding transfer device 16 are tilted toward the spinning machine base side, and the pegs 51 and 52 move forward to move the Masushino winding F. Sorashinomaki E
11 is transferred to a position directly below the hangers 4 and 5 of the removed Hinoshinomaki rails 2 and 3 to be in the state shown in FIG. 11 (a). In this state, the elevating board 20 is moved up and down in the same manner as described above, and all the pegs 30, 31, 51, 52 are simultaneously raised and immediately lowered. As a result, the Masushino winding F is suspended on the hangers 4 and 5, and the state shown in FIG. 13 is obtained. At this time, since the pegs 30 and 31 of the empty Shino winding transfer device 15 are not in a state corresponding to the hangers 11 and 12 suspended in the magazine 13, the empty Shino winding E remains as it is placed on the pegs 30 and 31. Become.

Next, the cylinder 67 is actuated, the piston rod 67a thereof projects, and the link mechanisms 53 and 54 return to their original positions. After that, the cylinder 75 is operated to pull in the piston rod 75a that was in the projecting position, and the substrate 57
Returns to the original position, and the pegs 51 and 52 are in a state of facing the hangers 11 and 12 suspended in the magazine 13. After the substrate 57 returns to the original position, the cylinder 37 is operated and the piston rod 37a thereof is projected, and the rotating substrate 29 is rotated to return to the original position. This allows pegs 30, 31
The empty Shino roll E placed on the top is in the state shown in FIG. 11 (b) corresponding to the hangers 11 and 12 suspended in the magazine 13. In this state, the cylinder 19 is actuated to move the elevating board 20 up and down, so that the pegs 30, 31, 51 and 52 simultaneously rise and immediately descend. And pegs 30, 31
The empty Shino roll E, which had been inserted in, is suspended on the hangers 11 and 12, and one cycle of the Shino change is completed. Next, the automatic transfer machine 14 moves to the next transfer position, and the transfer operation is repeated in the same manner as described above.

The empty Shino winding E and the Mana Shino winding F when the empty Shino winding E is taken out of the inner Shino winding rail 2 and when the Mana Shino winding F is supplied to the inner Shino winding rail 2 at the time of the changeover operation. Will contact the Shino guide 6, but as shown in FIG. 14, the Shino guide 6
If it is made rotatable and the springs 76 on both sides automatically return to the original position after the empty roll E and the full roll F have passed, no problem will occur.

The present invention is not limited to the above-described embodiment. For example, it is not necessary that one row of spare Shino windings be in a zigzag shape, and the relationship between the full Shino winding diameter D and the spindle gauge G is not limited. In the case of D <2G, the straight line can be perfectly aligned, and the specific configuration can be simplified. Further, as shown in FIG. 15, the shino guide 6 is made rotatable and the projection 77 provided on the shino guide 6 is rotatable.
By engaging the concave portion 79 of the fixing member 78 with the snap effect so that the rotated Shino guide 6 is held at the rotating position, the operator slightly applies force after the completion of the Shino change. Can be easily returned to the original position. Also, as shown in FIG. 16, the link mechanisms 32, 3
Of the three links, the links 43 and 45 with a small load are formed by rods, and the links 42 and 43 having a bent shape are connected to the small links 80
They may be connected to each other to maintain the parallel state. Further, in order to reduce the load when returning the tilted link mechanisms 32 and 33 to the upright state, the other end of the spring 81 having one end locked to the machine body is locked to the link 42, and the peg 3 is used.
An anti-sway member such as an air chuck 82 may be provided in order to prevent the bobbins inserted into the Nos. 0 and 31 from swaying when moving. In addition, positioning members 83 and 84 that regulate the turning position of the turning lever 47 and the tilting position of the link 42.
May be provided.

[0024]

As described above in detail, according to the present invention, since the inner and outer two rows of main shinomaki rolls are changed at once by the automatic changer, the changeover operation is simple and the number of rows is one. As a result of changing every other row for the specified number of spare Shino rolls, 1
The fact that Mitsunomaki and Sinomaki of medium balls are positioned in every row means that even in the case of small spindle gauges due to the speedup of small packages, the Mitsunomaki diameter should be as large as before. Can respond to. Further, it has an excellent effect that the method of the present invention can be easily adopted without largely changing the existing spinning frame.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supplying Shinobu to a spinning machine, and more specifically, to suspend the Shinoshinomaki for supplying Shino to the draft part in two rows inside and outside, and further to the outside of them. The present invention relates to a Shino feeding method in a spinning machine in which a spare Shino roll for suspension is suspended.

[0002]

2. Description of the Related Art In a spinning machine, a shinomaki is pulled out from a shinomaki suspended on a creel at a high position and is supplied to a lower draft part. In this case, Shino-maki has a considerably larger diameter than the spindle gauge of the spinning machine.
In general, Shino rolls are suspended on creel rails arranged in two rows, inside and outside. Then, as the supply to Shino's draft part progresses, and Shino-maki becomes empty or approaches the sky, it is necessary to replace it with a new Shino-maki. For this exchange
It has long been practiced for an operator to manually carry out Shino-maki carried by a dolly, or for the worker to replace a spare Shino-maki that is previously placed on a creel shelf. Further, in addition to the inner and outer two rows of creel rails, one rail is further provided on the outer side of the creel rail, and a spare shinomaki is hung on this rail, and the worker performs the exchange work as needed. There are also things. According to this type, the spare Shino-Maki rail is of a transport type and can be automatically loaded and unloaded from the roving process or one end of the spinning frame, and is therefore evaluated as a practical one.

By the way, Shinomaki has a large diameter and weighs 3 kg.
It is difficult to handle because it is in front and behind, and because the creel is in a high position, the exchange of Shino rolls (Shinome change) is a heavy labor for workers. From this, a device that automatically suspends Shino-maki on a creel hanger has come to be considered.
In Japanese Patent Laid-Open No. 58-81631 published on May 17, 1983, as shown in FIG. 15, a spare shinomaki 92 suspended from a spare shinomaki rail 91 and a shinko to a draft part 93 are supplied. There is proposed a device for automatically suspending an empty shinomaki on a spare shinomaki rail 91 for replacement of the present shinomaki. This device is the take-out arm 95 of the automatic changer 94.
By moving up and down and moving back and forth, the empty Shino winding 96 is taken out and suspended on the spare Shino winding rail 91, and instead, the spare Shino winding 92 of the rail 91 is suspended on the creel.

Since this device can only replace the Shino-maki suspended on the outside of the creel and the spare Shino-maki 92 suspended on the spare Shino-maki rail 91, the empty Shino-maki becomes empty. 9
It is necessary to suspend 6 on the outer rail 98. For this reason, the Shinozaki 96, which is suspended in the inner row, is supplied to the draft part 93 in a state where the diameters of the main Shinozaki 96, 97 suspended in two rows are different. When emptied, the Shino transfer machine 99 replaces the empty Honshinomaki 96 on the inside and the Honshinomaki 97 on the inside, respectively, prior to the operation of the automatic Shino-changing machine 94. ing.

[0005]

In the above-mentioned conventional Shino replacing method, the Shino replacing machine 99 for replacing the inner and outer rows of two main Shino rolls is indispensable prior to the automatic Shino replacing machine 94 replacing operation. Since the replacement machine 99 is equipped, the machine height becomes high. As a result, the spare Shino-Maki rail 91 also becomes higher, and the automatic Shino-Shin machine 9
The vertical movement amount of the take-out arm 95 of No. 4 also becomes large.

Further, in recent years, in order to speed up the spinning machine and save energy, the spinning yarn for spinning the spinning machine has been made into a small package, and accordingly, the spindle gauge (spindle pitch) has become smaller. On the other hand, it is desired to increase the diameter of the Shino winding in order to extend the replacement cycle. But,
In the Shino feeding method for carrying out the Shino replacing method, in order to prevent the main Shino winding suspended on the outer row of the creel from contacting the adjacent Shino winding when changing the Shino winding, The maximum diameter of the Shino winding must be smaller than twice the spindle pitch, and the demand for increasing the diameter of the Shino winding cannot be satisfied.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to suspend a main reel having a diameter larger than twice the spindle pitch on a creel to supply the reel. Moreover, it is an object of the present invention to provide a shino feeding method for a spinning machine, which makes it easy to take out an empty shinomaki creel and suspend it from a spare shinomaki at the time of replacement.

[0008]

In order to achieve the above-mentioned object, in the present invention, the main Shino-maki for supplying Shino to the draft part is suspended in two rows inside and outside along the longitudinal direction of the machine base. In the spinning machine, a predetermined amount of difference is provided in the amount of shino winding between the main shino windings adjacent to each other in the longitudinal direction of the machine base so that the shino windings of the respective main windings are supplied to the draft part. Further, it is preferable that the difference of the predetermined amount is half the winding amount of a full ball.

[0009]

The main shinomaki is suspended in two rows inside and outside along the longitudinal direction of the spinning machine base with a predetermined difference in the amount of shinoroll between adjacent main shinomaki in the machine longitudinal direction. Shino is supplied to the draft part with the operation of the machine base. Since there is a predetermined difference in the amount of Shino winding between adjacent Shino windings in the machine longitudinal direction, when replacing empty or approaching Shino winding with a spare Shino winding,
The amount of shinomaki of the main shinomaki suspended on both sides of the main shinomaki is smaller than that of the spare shinomaki by a predetermined amount. In other words, since the main Shino winding with the maximum Shino winding diameter does not line up continuously along the machine longitudinal direction, the maximum Shino winding diameter of the main Shino winding can be made larger than twice the spindle pitch. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. On the creel 1 of the spinning machine, two main and outer rows of main rails 2 and 3 are arranged parallel to the longitudinal direction of the machine base on both left and right sides of the machine base. Honshinomaki rails 2, 3
Each of them is equipped with hangers 4 and 5 at a pitch twice the spindle pitch. Shino drawn from the main shinomaki suspended from the hangers 4 and 5 passes through the shino guide 6 and the guide rod 7 and then the draft part. It is designed to be supplied to 8. A support bracket 9 is further extended outward from the creel 1, and a carrier rail 10 is provided at the tip of the support bracket 9 so as to extend in parallel with the main shinomaki rails 2, 3. Transport rail 10
A magazine 13 including hangers 11 and 12 arranged in a zigzag shape is suspended in the carriage so that the magazine 13 can run. The hangers 11 and 12 arranged in a zigzag form correspond to the spare shinomo row. Each of the hangers 4, 5, 11, and 12 has a structure that can be suspended or removed from the hangers 4, 5, 11, and 12 by moving the Shino-maki up and down. Although the number of hangers 11 and 12 mounted on one magazine 13 is not limited, as shown in FIG. In the condition that the pitch is the same as the hanger of Honshinomaki rails 2 and 3, the hanger 11,
It is arranged in a staggered manner so that the Masushino winding F suspended on 12 does not come into contact.

That is, in recent years, in order to speed up the spinning machine and save energy, the spinning yarn for spinning the spinning machine has been made into a small package, and the spindle gauge G has been reduced accordingly. On the other hand, it is desired that the maximum Shino winding diameter D be increased in order to extend the Shino replacement cycle. Therefore, D ≧ 2G
In this case, the single row of spare Shino-maki has a zigzag pattern as in this embodiment.

[0012] In addition, in one row of spare Shino-maki, one side of the spinning machine 2
Since it is not possible to secure the number of Honshino-maki in a row, the first Honshino-maki group composed of two Honshino-maki windings located inside and outside every other one, and the second Honshino-maki arranged alternately. It is divided into two types, the Honshinomaki group. That is, it is divided into a Honshino winding group consisting of odd-numbered Honshino windings arranged in a direction orthogonal to the longitudinal direction of the machine base and a Honshino winding group consisting of even-numbered Honshino windings. Then, spinning is performed in a state where a difference of a predetermined amount is provided in the amount of the main winding of the both main winding groups. In this embodiment, FIG.
As shown in (a), spinning is performed while suspending every other Mitsunomaki F and Minoshinomaki M, which is half the amount of Mitsunomaki (full-ball) F. Be started. When the spinning process is continued and the middle ball Shinanomaki M that constitutes one Honshinomaki group becomes empty, the empty Shinanomaki that constitutes the Honshinomaki group is replaced. At this time, the Manami Shino roll F at the start of spinning becomes the middle ball Shinano roll M as shown in FIG. Therefore, even when the bobbin hangers 4 and 5 are closely spaced, the Masushino winding F contacts the Homoshino winding when replacing the Masushino winding F of the spare Shino winding row and the empty Shino winding E of the Honshino winding rails 2 and 3. Can be prevented. This also promotes an increase in the Mitsuno winding diameter.

Next, the automatic transfer device 14 for exchanging the full Shino winding F of the spare Shino winding and the empty Shino winding E of the main Shino winding will be described. The automatic Shino transfer machine 14 takes out the empty Shino roll E from the main Shino roll and suspends it on the hangers 11, 12 of the magazine 13, and the empty Shino roll transfer device 15 and the spare Shino roll F Equipped with a Masushino winding transfer device 16 that suspends the Masushino winding F at the position where the Sky Shino winding E of the main Shino winding is removed, and extends to the front of the spinning machine base.

Has been done. As shown in FIGS. 5 and 6, the turning mechanism of the turning board 29 has a turning lever 35 rotatably supported on a support shaft 34 fixedly mounted on the elevating board 20, and one end of the turning lever 35. A link 36 having the other end at the tip of the turning lever 35 rotatably connected to the lower surface of the turning board 29 by pins 36a and 36b, and a base end rotatably fixed on the elevating board 20. At the same time, the tip of the piston rod 37a is composed of a cylinder 37 which is pin-connected to substantially the center of the rotary lever 35. That is, the rotation lever 35, the link 36, and the rotation base plate 29 constitute a link mechanism, and the rotation base plate 29 rotates about the support shaft 28 due to the piston rod 37a protruding and retracting due to the operation of the cylinder 37. .

The peg 3 is provided on the upper surface of the rotating substrate 29.

The link 42 is integrally rotatably fixed to a rotary shaft 46 that is rotatably supported by the support bracket 38, and a rotary lever 47 is integrally rotatably connected to the rotary shaft 46. . The pivot lever 47 has a base end at its tip end, which has a base end erected on the pivot base plate 29 (shown in FIG. 4).
Is connected to a piston rod 49a of a cylinder 49 fixed via a bracket. Further, the link 44 and the link 42 are connected by the connecting member 50 in order to interlock the link mechanism 32 for driving the peg 30 and the link mechanism 33 for driving the peg 31. The connecting position of the connecting member 50 is such that when the peg 30 moves forward to a position corresponding to the inner main wrapping rail 2, the peg 31 moves forward with a slight delay and finally corresponds to the outer main wrapping rail 3. It is set to stop.

Accordingly, the cylinder 49 is operated and the piston rod 49a is pulled in, whereby the link mechanism 3
When the pegs 30 and 31 are held in the upright state, the pegs 30 and 31 are moved forward to the positions corresponding to the main shinowaki rails 2 and 3 shown by the chain line in FIG. In addition,
Both links 42 and 43 are formed in a bent shape because they do not contact the draft part 8.

It is to be noted that the intervals c between the lower ends of the bobbins and the pegs 30 and 31 are designed to be the same at the main shino-roll position and the preliminary shino-roll position. Next, Mitsunomaki transfer device 16
Will be described. The Mitsushino winding transfer device 16 is arranged adjacent to the Sorashino winding transfer device 15, and like the Sorashino winding transfer device 15, two pegs that can be fitted into the bottom of the bobbin that is the core of the Shino winding. 51 and 52 can be independently moved back and forth by link mechanisms 53 and 54. Link mechanism 5
Similar to the link mechanisms 32 and 33 of the Kushino Shinko transfer device 15, 3 and 54 are parallel four-bar links, but the support brackets 55 and 56 as fixed links are displaced instead of the rotating substrate 29. Substrate 5 displaced by the mechanism
7 is different from the above-mentioned Sorashino winding transfer device 15 in that it is fixedly installed on the device 7. The link mechanism 53 includes a support bracket 55 as a fixed link, links 58 and 59 whose base ends are rotatably connected to the support bracket 55, and the links 58 and 59.

A piston rod 67a of a cylinder 67 fixed to a column 66 (illustrated in FIG. 4) standing upright via a bracket.
Are linked to. Further, the link mechanism 53 and the link mechanism 5
The link 58 and the link 61 are connected to each other by the connecting member 68 in order to interlock them with each other.

Next, the displacement mechanism of the substrate 57 will be described. The substrate 57 is used as the rotating substrate 29 of the Sorashino winding transfer device 15.
Although it is possible to displace it to a predetermined position by rotational movement similarly to the above, since the automatic shinning machine 14 of this embodiment has a narrow machine frame, the center of rotation is outside the machine frame. A displacement mechanism consisting of a four-bar linkage is used. As shown in FIGS.
9 and 70 are vertically fixed, the base ends of links 71 and 72 are rotatably supported by both support shafts 69 and 70, and the other ends of both links 71 and 72 are of a base plate 57 that acts as a link. The lower surface is rotatably connected by pins 73 and 74. A base end of the link 71 is connected to a piston rod 75a of a cylinder 75 fixed on the elevating board 20. Therefore, the operation of the cylinder 75 causes the four-bar linkage mechanism to be displaced, so that the substrate 57 forming a part thereof is displaced between predetermined positions.

Next, a description will be given of the changing operation by the automatic changing machine 14. As the spinning progresses, as shown in FIG. 9 (a), one group consisting of every other Honshinomaki becomes the empty Shinanomaki E and the other group becomes the Honshinomaki M. The automatic transfer machine 14 starts traveling from one end of the spinning machine base, stops at a predetermined transfer position, and becomes the state shown in FIG. 9 (a). At this time, each peg 30, 31 is a hanger 1 mounted on the magazine 13.
The pegs 51 and 52 are located directly below the Masushino winding F suspended in the magazine 13 so as to oppose the Nos. 1 and 12. Next, the cylinder 37 of the empty transfer device 15 is actuated and the piston rod 37a thereof is pulled in, and the rotating substrate 29 is rotated about the support shaft 28 in the counterclockwise direction of FIG. The state becomes as shown in. Next, the cylinder 49 is actuated to pull in the piston rod 49a, the link mechanisms 32 and 33 are tilted toward the spinning machine base side through the turning lever 47, and the pegs 30 and 31 are respectively moved to the main winding rails 2. 10A and FIG.
The state shown in 2 (a) is obtained. In this state, the cylinder 19 is operated, and the piston rod 19a thereof is projected again by a predetermined amount and then retracted again. As a result, the elevating board 20 is moved up and down, and all the pegs 30, 31, 51, 52 are simultaneously raised and simultaneously descended accordingly.
The empty winding E and the full winding F are respectively inserted into 1, 51 and 52, and the state shown in FIG.

Next, the cylinder 49 is actuated and the piston rod 49a thereof is projected, and the link mechanisms 32 and 33 that were in the forward tilted state are returned to their original positions. On the other hand, during this period, the cylinder 75 of the Mitsuno winding transfer device 16 is actuated, the piston rod 75a thereof is projected, and the substrate 57 is displaced.
The state shown in FIG. Next, the cylinder 67 is actuated, the piston rod 67a is pulled in, the link mechanisms 53, 54 of the Mitsuno winding transfer device 16 are tilted toward the spinning machine base side, the pegs 51, 52 move forward, and the Masushino winding F moves. 11 is transferred to a position directly below the hangers 4 and 5 of the main Shino winding rails 2 and 3 from which the empty Shino winding E has been removed, and the state shown in FIG.
In this state, the elevating board 20 is moved up and down in the same manner as described above, and all the pegs 30, 31, 51, 52 are simultaneously raised and immediately lowered. As a result, the Masushino winding F is suspended on the hangers 4 and 5, and the state shown in FIG. 13 is obtained. At this time, since the pegs 30 and 31 of the empty Shino winding transfer device 15 are not in a state corresponding to the hangers 11 and 12 suspended in the magazine 13, the empty Shino winding E remains as it is placed on the pegs 30 and 31. Become.

Next, the cylinder 67 is operated, the piston rod 67a thereof projects, and the link mechanisms 53 and 54 return to their original positions. After that, the cylinder 75 is operated to pull in the piston rod 75a that was in the protruding position, and the substrate 5
7 returns to the original position and pegs 51 and 52 are in the magazine 13
It is in a state of facing the hangers 11 and 12 suspended on the. After the substrate 57 is returned to the original position, the cylinder 37 is operated and the piston rod 37a thereof is projected, so that the rotating substrate 2
9 is rotated and returns to the original position. This makes peg 3
The sky Shino roll E placed on 0 and 31 is in the state shown in FIG. 11B corresponding to the hangers 11 and 12 suspended in the magazine 13. In this state, the cylinder 19 is actuated and the elevating board 20 is moved up and down to move the pegs 30, 31, 51, 52.
Rises all at once and falls immediately. And peg 3
The sky Shinano winding E inserted in 0,31 is the hanger 11,1
Suspended on No.2, one cycle of Shino changing is completed. Next, the automatic transfer machine 14 moves to the next transfer position, and the transfer operation is repeated in the same manner as described above.

The empty Shino winding E and the Mana Shino winding F are used when the empty Shino winding E is taken out of the inner Shino winding rail 2 and when the Mana Shino winding F is supplied to the inner Shino winding rail 2 at the time of changing over. Will contact the Shino guide 6, but as shown in FIG. 14, the Shino guide 6 can be rotated, and after passing the empty Shino winding E and the Mano Shino winding F, the springs on both sides automatically move the original position. No problem will occur if you return to.

The present invention is not limited to the above embodiment, and for example, the main winding rail 2, at the start of spinning.
The difference in the amount of Shino winding of the main Shino roll suspended on 3 is not limited to half the amount of full balls, and one Shino roll group suspended every other one is set as Mano Shina roll, and the other book The Shino-roll group may have 7-minute balls or 6-minute balls, and the difference in the Shino-roll amount between the two main Shino-roll groups may be 30% or 40% of the full-roll amount. In this case, the difference in the amount of Shinano winding that is newly suspended on the Shinano winding rails 2 and 3 by the next Shino replacement and the amount of Shino winding that is still spinning is 7 It will be 60% or 60%. Then, after the completion of the next Shino change, the difference in Shino winding amount becomes 30% or 40% of the winding amount of the full ball again. Further, it is not necessary for the single preliminary winding row to be in a zigzag shape, and when the relationship between the full winding diameter D and the spindle gauge G is D <2G, they can be perfectly aligned.

[0025]

As described in detail above, according to the present invention, the main Shino rolls that are suspended on the main Shino roll rail and supply the Shino to the draft part are mutually adjacent in the longitudinal direction of the machine base. Since there is a predetermined difference in the amount of Shino winding, the winding diameter of full Shino winding, that is, the maximum winding diameter of main Shino winding can be made larger than twice the spindle pitch, and the Shino replacement cycle can be extended. In addition, even in the case of a small package and a small spindle gauge that accompanies higher speeds, it is possible to meet the demand to use a large Masushino winding diameter as before. In addition, since the distance between adjacent Honoshimaki suspended on the same Honshinomaki rail is large at the time of replacement, the Shino-maki do not come into contact with each other even when they shake in the longitudinal direction of the spinning machine, and the shino-maki does not fluff. Further, since the inner and outer rows of the main Shino-maki are changed at once at the time of changing the Shino-Kin, the Shino-Maki becomes easy because there is no obstruction in the take-out direction when the inner Shino-Maki is taken out in the horizontal direction. In addition, since one half of the main shinomaki is replaced at the time of replacement, one row of spare shinomaki can be used.
