Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Field of Industrial Application) The present invention relates to a method for changing the threads of a spinning machine, and more specifically, the present invention relates to a method for changing the threads of a spinning machine. In a spinning machine which is suspended in rows and further suspends spare Shinomaki to be replaced with the above-mentioned Honshinomaki on the outside thereof, the exchange between the Honshinomaki and the spare Shinomaki is automatically carried out. This relates to the Shinokae method.

(Prior Art) In a spinning machine, the thread is pulled out from a thread roll suspended from a creel at a high position and is supplied to a draft part below. In this case, since the Shinomaki has a considerably larger diameter than the spindle gauge of the spinning machine, the Shinomaki is generally suspended from creel rails arranged in two rows, one inside and one outside. Then, as the supply to the draft part of Shino progresses and the Shino roll is empty or near empty, it is necessary to replace it with a new Shino roll. Regarding this replacement (shinomaki), the worker manually replaces the shinomaki transported by a trolley, or the same worker replaces the spare shinomaki that has been placed on the creel shelf in advance. This has been done for a long time. Further, in addition to the two rows of creel rails inside and outside, one additional rail is provided on the outside thereof,
There is also a type in which a spare shinomaki is suspended from this, and an operator performs the replacement work as necessary. According to this type, the preliminary winding rail is of a conveying type and can be automatically carried in and taken out from the roving process or one end of the spinning machine, and is therefore evaluated as a practical device.

By the way, the shinomaki has a large diameter and weighs around 3 kg, making it difficult to handle, and the creel is located at a high position, making replacing the shinomaki (shinokae) a heavy labor for the worker.

This led to the idea of a device that automatically suspends Shinomaki from a creel hanger. The method described in Japanese Patent Publication No. 1983-22848 published on July 9, 1970 is being considered. However, with this device, the spare shinomaki placed in a horizontal position must be changed to an upright position, so the mechanism of the automatic machine is robust and complicated, and the operator has to lift the empty shinomaki at a high price. It has the disadvantage that it must be removed from the creel in advance. In order to eliminate this drawback, as shown in Figure 14, Japanese Patent Application Laid-Open No. 58-81631 published on May 17, 1988,
Spare Shinomaki 9 suspended on preliminary Shinomaki rail 91
2 is replaced with a genuine Shinomaki that supplies Shino to the draft part 93, a device has been proposed that automatically suspends the empty Shinomaki from the spare Shinomaki rail 91. In other words, the take-out arm 9 of the automatic shino change machine 94
5 moves up and down and back and forth to take out the empty shinimaki 96 and hang it on the preliminary shinimaki rail 91, and in turn suspend the auxiliary shinimaki 92 on the rail 91 from the creel. However, this device has various problems because it does not take into consideration the simultaneous replacement of the two rows of inner and outer Honshinomaki 96, 97. That is, in order to make it easier for the automatic Shino change machine 94 to work on one row of spare Shino-maki rails 91, the main Shino-maki 96,
It is necessary to make a difference in the diameter of the rolled balls 97 and to hang the empty Honshinomaki 96 on the outer rail 98 without fail. For this purpose, a Shino-swapping machine 99 is equipped to exchange the inner and outer Shino-maki 96, 97, and before exchanging with the spare Shino-maki 92, this Shino-swapping machine 99 replaces the empty main Shino-maki 96 on the inside with the outer one. Nakatama Honshinomaki 97
are replaced inside. Therefore, since the machine height becomes higher and the preliminary shin winding rail 91 also becomes higher, the vertical movement of the take-out arm 95 of the automatic shin changer 94 also increases.

In order to solve these drawbacks, the present inventor previously proposed a method of sequentially replacing the two rows of main shinomaki with two spare shinomaki at the same time, but this method has some disadvantages. This means that the preliminary Shinomaki must be arranged in two rows.

(Problems to be Solved by the Invention) This invention solves the problem that, in the conventional automatic Shino-maki method, it is necessary to replace the inner and outer Shino-maki before replacing the spare Shino-maki and the main Shino-maki. Not only does the height of the machine become high due to the installation of a Shino shunting machine that performs point and replacement work, which makes maintenance management difficult, but it is also difficult to adopt it in an existing factory. This solves problems such as the complexity of winding preparation and the difficulty of installing a traveling cleaning device due to the large width of the machine.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in this invention, the main shinomaki that supplies the shinino to the draft part are suspended in two rows inside and outside in the longitudinal direction of the machine base. At the same time, in a spinning machine in which preliminary Shinomakis are suspended outside the spinning machines, the preliminary Shinomakis are arranged in a row,
The above-mentioned two rows of inner and outer honshinomaki located every other time along the longitudinal direction of the machine base are the first honshinomaki group, and other honshinomakis located alternately with them along the longitudinal direction of the machine base. is defined as the second Honshinomaki group, and a predetermined amount is added to the Shinshinomaki of the Honshinomaki of the first Honshinomaki group and the Honshinomaki of the second Honshinomaki group that are adjacent in the longitudinal direction of the machine stand. A method is adopted in which the trains are operated with a difference, and when one of the Honshinomaki groups is empty or close to empty, the Honshinomaki of the two rows of Honshinomaki and the outside of the same Honshinomaki group are replaced with the spare Shinomaki of the backup Shinomaki line. did.

(Function) In this invention, the preliminary shinomaki are arranged in one row, and the spinning machine is operated by using the first shinomaki consisting of two inner and outer rows of main shinomaki located every other time along the longitudinal direction of the spinning machine frame. A state in which the Honshinomaki of the Honshinomaki group and the Honshinomaki of the second Honshinomaki group consisting of Honshinomaki located alternately with the Honshinomaki group are suspended with a predetermined difference in the amount of Shinobu. It is spun in Then, when one of the Hon-Shinomaki groups becomes empty or nearly empty, the Hon-Shinomaki in the two rows of inner and outer rows of the Hon-Shinomaki group are replaced with the spare Shinomaki of the preliminary Shinomaki row.

When replacing an empty or nearly empty Honshinomaki with a spare Shinomaki, the Honshinomaki suspended on both sides of the Honshinomaki has a predetermined amount less Shinomaki than the spare Shinomaki, and the Honshinomaki is Even if the spacing between the two is narrow, the preliminary shinomaki will not come into contact with the main shinomaki that is currently being spun during replacement.

(Embodiment) An embodiment embodying the present invention will be described below with reference to the drawings. The creel 1 of the spinning machine has two rows of Honshinomaki rails 2 and 3 on the left and right sides of the frame, respectively, inside and outside.
are arranged parallel to the longitudinal direction of the machine. The Honshinomaki rails 2 and 3 are each equipped with hangers 4 and 5 that maintain a pitch twice the spindle pitch, and the Shino drawn out from the Honshinomaki suspended from the hangers 4 and 5 is carried by a Shino guide 6. and is supplied to a draft part 8 via a guide rod 7. A support bracket 9 further extends outward from the creel 1, and a conveyor rail 10 is provided at the tip of the support bracket 9, extending parallel to the main rails 2 and 3. A magazine 13 having hangers 11 and 12 arranged in a staggered manner is suspended from the transport rail 10 so as to be movable. The hangers 11 and 12 arranged in a staggered manner correspond to a preliminary Shinomaki row. Each of the hangers 4, 5, 11, 12 has a structure that allows the hangers 4, 5, 11, 12 to be suspended from or removed by moving the shinomaki up and down. Although the number of hangers 11 and 12 equipped in one magazine 13 is not limited,
In order to minimize the space occupied by the spare Shinomaki row, as shown in Figure 2, the adjacent hanger 1
The pitches of 1 and 12 are the same as the hangers of Honshinomaki rails 2 and 3, and hanger 1
The Manshinomaki F suspended from 1 and 12 are arranged in a staggered manner so that they do not come into contact with each other.

That is, in recent years, spinning machines have been made smaller in size in order to increase their speed and save energy, and the spindle gauge G has also become smaller accordingly. On the other hand, it is desired that the diameter D of the Shino winding be increased in order to extend the Shino change cycle. Therefore, in the case of D≧2G, one row of preliminary shinumaki will have a staggered pattern as in this embodiment.

In addition, with one row of spare Shinomaki, two sides of the spinning machine stand are installed.
Since it is not possible to secure a row of honshinomaki, the honshinomaki is divided into the first honshinomaki group, which consists of two rows of honshinomaki, one inside and one outside, located every other piece along the longitudinal direction of the spinning machine frame. , and the second Honshinomaki group consisting of Honshinomaki located alternately. That is, they are divided into a Hon-Shinomaki group consisting of odd-numbered rows of Hon-Shinomaki arranged in a direction perpendicular to the longitudinal direction of the machine base, and a Hon-Shinomaki group consisting of even-numbered Hon-Shinomakis. Then, spinning is performed in a state where a predetermined amount of difference is provided between the amounts of shinomaki of the shinomaki of both shinomaki groups. In this embodiment, spinning is started with every other full-sized Shinomaki F and medium-sized Shinomaki M suspended from the hangers 4 and 5. When the spinning continues and the medium-sized shinomaki M constituting one of the main shinomaki groups becomes empty, the empty shinomaki constituting the main shinomaki group will be replaced. At this time, the full-sized Shino-maki F at the start of spinning becomes a medium-sized Shino-maki M, as shown in FIG. Therefore, even if the interval between the bobbin hangers 4 and 5 is narrow, the full Shinomaki F of the preliminary Shinomaki row and the main Shinomaki rail 2,
When replacing the blank shinomaki E of No. 3, it is possible to prevent the full shinomaki F from coming into contact with the main shinomaki. This also promotes increasing the diameter of the Mitsushi winding.

Next, the automatic Shino-maki machine 14 for exchanging the full Shino-maki F of the preliminary Shino-maki row and the empty Shino-maki E of the main Shino-maki row will be explained. The automatic Shino-maki changing machine 14 includes an empty Shino-maki transfer device 15 that takes out the empty Shino-maki E from the main Shino-maki row and suspends it from the hangers 11 and 12 of the magazine 13, and an empty Shino-maki transfer device 15 that takes out the empty Shino-maki E from the main Shino-maki row and suspends it from the hangers 11 and 12 of the magazine 13, and a full Shino-maki F from the preliminary Shino-maki row. Equipped with a full-scale winding transfer device 16 that functions to suspend the full-scale winding F at the position from which the empty winding E of the main Shino-winding row has been removed, and is extended to the front of the spinning machine frame. The spinning frame is configured to travel along the spinning frame via guide rollers 18 that engage with guide rails 17 that have been rotated.

The automatic grain changing machine 14 is provided with an elevating base plate 20 which is connected to a piston rod 19a of a cylinder 19 fixed to the grain changing machine 14 and moves up and down while maintaining a horizontal state by the operation of the cylinder 19. As shown in FIGS. 3 and 4, pillars 21 are erected on both left and right sides of the upper surface of the lifting board 20.
There are rails 22 fixed vertically to the machine frame on both the top and bottom sides of the machine.
Regulating rollers 23 and 24 are attached that engage with and restrict the lifting board 20 to maintain a horizontal state. Further, pulleys 27 for guiding a tape 26, which has one end connected to a balance weight 25 and the other end connected to the support column 21, are rotatably supported on the left and right upper portions of the automatic grain changer 14. That is, by the operation of the cylinder 19, the lifting board 20 is smoothly moved up and down while maintaining a horizontal state.

On the lifting board 20, an empty winding transfer device 15 and a full winding winding transfer device 16 are arranged adjacent to each other. The dry winding transfer device 15 is horizontally fixed to the upper end of a support shaft 28 that is rotatably disposed on the lifting board 20, and has a rotating board 29 that is rotated by a rotating mechanism.
and a link mechanism for moving the pegs 30 and 31, which are arranged on the rotary board 29 and can be fitted into the bottom of the bobbin that is the core of the shinomaki, between the preliminary shinomaki row and the main shinomaki row. 32 and 33. As shown in FIGS. 5 and 6, the rotating mechanism of the rotating board 29 includes a rotating lever 3 rotatably supported on a support shaft 34 fixed on the lifting board 20.
5, one end is at the tip of the rotating lever 35, and the other end is at the lower surface of the rotating base plate 29, respectively.
Link 36 rotatably connected by 36b
and a cylinder 37 whose base end is rotatably fixed on the elevating base plate 20 and whose distal end of a piston rod 37a is connected with a pin to approximately the center of the rotary lever 35. That is,
The rotating lever 35, the link 36, and the rotating base plate 29 constitute a link mechanism, and the rotating base plate 29 rotates about the support shaft 28 when the piston rod 37a moves in and out due to the operation of the cylinder 37.

On the upper surface of the rotating board 29, the peg 30,
Support brackets 38 and 39, which correspond to fixed links of the parallel four-bar links of the link mechanisms 32 and 33 for moving the support bracket 31 back and forth, are fixedly provided. Each support bracket 38, 39 has the peg 30,
Two links 42, 43, 44 whose tips are connected with pins to support plates 40, 41 having 31,
45 is rotatably supported at its proximal end. That is, the support bracket 38, the support plate 40
and links 42 and 43 constitute one link mechanism 32, and support bracket 39, support plate 41, and links 44 and 45 constitute another link mechanism 33. The link 42 is rotatably fixed to a rotation shaft 46 which is rotatably supported on the support bracket 38, and a rotation lever 47 is connected to the rotation shaft 46 so as to be integrally rotatable. . The rotary lever 47 has its distal end connected to the piston rod 4 of a cylinder 49 whose base end is fixed via a bracket to a column 48 erected on the rotary base plate 29.
9a. Further, in order to interlock the link mechanism 32 that drives the peg 30 and the link mechanism 33 that drives the peg 31, the link 44 and the link 42 are connected by a connecting member 50.
The connecting position of the connecting member 50 is such that when the peg 30 moves forward to a position corresponding to the inner Honshinomaki rail 2, the peg 31 moves forward with a slight delay and finally reaches the position corresponding to the outer Honshinomaki rail 3. It is set to stop.

Therefore, when the cylinder 49 is actuated and the piston rod 49a is retracted, the link mechanisms 32 and 33 are rotated in conjunction with each other, and the pegs 30 and 31 are rotated.
are moved forward to positions corresponding to the Honshinomaki rails 2 and 3 shown by chain lines in FIG. 1 while being held upright respectively. Note that both links 42 and 43 are formed in a bent shape so that they do not come into contact with the draft part 8.

It should be noted that the design is such that the distance c between the lower end of the bobbin and the pegs 30, 31 at the main winding position and the preliminary winding position are all the same.

Next, the Mitsshinomaki transfer device 16 will be explained. The Mitsushi roll transfer device 16 is arranged adjacent to the empty Shino roll transfer device 15, and similarly to the empty Shino roll transfer device 15, it has two pegs that can be fitted into the bottom of the bobbin that is the core of the Shino roll. 51 and 52 can be moved back and forth independently by link mechanisms 53 and 54, respectively. The link mechanisms 53 and 54 are connected to the Shinomaki transfer device 1, respectively.
Like the link mechanisms 32 and 33 of No. 5, it is composed of parallel four-bar links, but the support brackets 55 and 56 as fixed links are fixedly mounted on a base plate 57 that is displaced by a displacement mechanism instead of the rotating base plate 29. This is different from the empty winding transfer device 15 in that it is. 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 are connected to the tips of the links 58 and 59 so as to be in a horizontal state. It consists of a support plate 60 having pegs 51. The link mechanism 54 includes a support bracket 56 as a fixed link, and a support bracket 56 as a fixed link.
Two links 6 whose base ends are rotatably connected to
1 and 62, and a support plate 63 which is horizontally connected to the tips of the links 61 and 62 and has pegs 52. A rotary lever 65 is connected to a rotary shaft 64 to which a link 58 is rotatably fixed.
5 is a column 66 whose base end is erected on the substrate 57;
It is connected to a piston rod 67a of a cylinder 67 (shown in FIG. 4) via a bracket. Moreover, the link mechanism 53 and the link mechanism 54
The link 58 and the link 61 are connected by a connecting member 68 in order to interlock them.

Next, the displacement mechanism of the substrate 57 will be explained. It is also possible to displace the board 57 to a predetermined position by rotational movement similar to the rotary board 29 of the empty wire winding transfer device 15, but since the automatic wire changing machine 14 of this embodiment has a narrow machine frame width. Since the center of rotation is outside the machine frame, the device of this embodiment employs a displacement mechanism consisting of a four-bar link mechanism. As shown in FIGS. 7 and 8, support shafts 69 and 70 are vertically fixed on the lifting board 20, and links 7 and 70 are provided on both support shafts 69 and 70.
The base ends of the links 71 and 72 are rotatably supported, and the other ends of both links 71 and 72 are connected to the base plate 5 that acts as a link.
It is rotatably connected to the lower surface of 7 by pins 73 and 74. The link 71 has a base end connected to a piston rod 75a of a cylinder 75 fixed on the elevating base plate 20. Therefore cylinder 75
As a result of the operation, the four-bar linkage mechanism is displaced, and the base plate 57 forming a part of the four-bar linkage mechanism is displaced between predetermined positions.

Next, a description will be given of the sash changing operation performed by the automatic sash changing machine 14. As spinning progresses, as shown in Fig. 9a, one group of Honshinomaki consisting of every other Honshinomaki suspended from Honshinomaki rails 2 and 3 becomes empty Honshinomaki E, and the other Honshinomaki becomes Empty Honshinomaki. When the main Shino-maki of the winding group becomes the medium-sized Shino-maki M, the automatic Shino change machine 14 starts running from one end of the spinning machine frame and stops at a predetermined Shino change position, resulting in the state shown in FIG. 9a. becomes. At this time, each peg 30, 31 is attached to the magazine 13.
The pegs 51, 52 are located directly below the Manshinomaki F suspended from the magazine 13, facing the hangers 11, 12 installed in the magazine 13. Next, the cylinder 37 of the empty winding transfer device 15 is activated, its piston rod 37a is retracted, and the rotary base plate 29 is rotated about the support shaft 28 in the counterclockwise direction in FIG.
The state shown in is reached. Next, the cylinder 49 is activated and its piston rod 49a is retracted, and the link mechanisms 32 and 33 are tilted toward the spinning machine frame side via the rotation lever 47, and the pegs 30 and 31 are moved to the Honshinomaki rails 2 and 3, respectively. It moves forward to a position directly below the empty winding E suspended from the air, and the state shown in FIGS. 9c and 10a is reached. In this state, the cylinder 19 is operated and its piston rod 19a is extended by a predetermined amount and then retracted. As a result, the elevating board 20 is moved up and down, and all the pegs 30, 31, 51, 5 are moved up and down accordingly.
2 rise all at once and then immediately descend, so that empty windings E and full windings F are fitted into each peg 30, 31, 51, 52, respectively, resulting in the state shown in FIG. 10b. Next, the cylinder 49 is actuated to project its piston rod 49a, and the link mechanisms 32, 33, which have been in a tilted state, return to their original positions. Meanwhile, during this time, the cylinder 75 of the full-volume winding transfer device 16 is operated, its piston rod 75a projects, and the base plate 57 is displaced, resulting in the state shown in FIG. 9d.
Next, the cylinder 67 is actuated, its piston rod 67a is retracted, and the link mechanisms 53 and 54 of the full-roll transfer device 16 are tilted toward the spinning machine frame, and the pegs 51 and 52 move forward to move the full-length roll F above the Hangers 4 and 5 of Honshinomaki rails 2 and 3 from which Karashinomaki E has been removed
is transferred to a position directly below , resulting in the state shown in FIG. 9e. In this state, the lifting board 20 is moved up and down in the same manner as above, and all the pegs 30, 31, 51, 52
rise all at once and immediately fall. As a result, the Manshinomaki F is suspended from the hangers 4 and 5, resulting in the state shown in FIG. 10c. At this time, Karashinomaki transfer device 1
Since the pegs 30 and 31 of No. 5 are not in correspondence with the hangers 11 and 12 suspended from the magazine 13, the blank roll E remains placed on the pegs 30 and 31 as they are.

Next, the cylinder 67 is actuated and its piston rod 67a projects, and the link mechanisms 53 and 54 return to their original positions. Thereafter, the cylinder 75 is actuated to retract the piston rod 75a, which has reached the protruding position, and the base plate 57 returns to its original position, causing the pegs 51, 5
2 is a hanger 11, 1 suspended from a magazine 13
It will be in a state opposite to 2. After the base plate 57 returns to its original position, the cylinder 37 is actuated to project its piston rod 37a, and the rotating base plate 29 is rotated to return to its original position. As a result, Petsugu 30, 31
The blank roll E placed on top is in the state shown in FIG. 9f, where it corresponds to the hangers 11 and 12 suspended from the magazine 13. In this state, the cylinder 19 is operated to raise and lower the lifting board 20, and the pegs 30, 3
1, 51, and 52 rise all at once and immediately fall. The blank windings E inserted into the pegs 30 and 31 are suspended from the hangers 11 and 12, and one cycle of changing the windings is completed. Next, the automatic shading changing machine 14 moves to the next shading changing position, and the shading changing operation is repeated in the same manner as described above.

Empty Shino-maki E and full Shino-maki F are used as Shino guides when taking out empty Shino-maki E from the inner real Shino-maki rail 2 during Shino change work, and when supplying full Shino-maki F to the inner real Shino-maki rail 2. However, as shown in Fig. 11, the Shino guide 6 is made rotatable, and after the empty Shino-maki E and the full Shino-maki F pass, it automatically returns to its original position by the springs 76 on both sides. If you do this, there will be no problem.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, one row of preliminary Shino windings does not need to be staggered;
If the relationship is D<2G, it can be a completely straight line, so the specific configuration can be simplified. Moreover, as shown in FIG. 12, the Shino guide 6 is made rotatable,
By fitting the protrusion 77 provided therein into the recess 79 of the fixing member 78 with a snap effect, the rotated shinobi guide 6 can be held in the rotated position. A person can easily return it to its original position by applying a slight force. Furthermore, as shown in FIG. 13, among the links of the link mechanisms 32 and 33, the links 43 and 45, which have a smaller load, are formed by rods, and the bent links 42 and 43 are connected to each other by a small link 80 to maintain a parallel state. You may also do so. In addition, in order to reduce the load when returning the tilted link mechanisms 32, 33 to an upright state, the other end of the spring 81, whose one end is latched to the fuselage, is latched to the link 42 or inserted into the pegs 30, 31. In order to prevent the bobbin from swinging during movement, an anti-swaying member such as an air chuck 82 may be provided. Further, positioning members 83 and 84 may be provided to restrict the rotational position of the rotational lever 47 and the tilting position of the link 42.

Effects of the Invention As described in detail above, according to the present invention, since the automatic shinomaki changing machine changes the shinomaki in two rows, the inner and the outer, at the same time, the shinomaki become an obstacle in the direction of taking out the shinomaki when changing the shinomaki. Since there is no shinomaki, the shinomaki can be taken out horizontally, making it easy to replace the shinomaki. Moreover, when changing the shinomaki, half of the original shinomaki is always replaced, so one row of spare shinomaki can be used. In addition, since every other piece of shinomaki is hung with a predetermined difference in the amount of shinomaki,
Even in the case of small spindle gauges due to the increase in speed of small packages, it is possible to meet the demand for the use of larger Mitsushi winding diameters as in the past. Furthermore, an excellent effect is achieved in that the method of the present invention can be easily adopted without significantly changing an existing spinning frame.
