Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-node ring lifting device for spinning machines such as ring spinning machines and ring twisting machines having ring rails and lappet angles.

[0002]

2. Description of the Related Art Generally, in this type of spinning machine, in order to form a yarn, the ring rail is gradually raised while repeating the raising and lowering motion of the ring rail during the operation of the machine base, and the lappet angle and the antinode are synchronized with it. Raise and lower the ring etc. The anti-node ring suppresses the excessive outward ballooning (ballooning) between the snell wire and the traveler during spinning. Then, the yarns of the adjacent weights are prevented from interfering with each other due to the increased ballooning, and the ballooning is regulated to a size suitable for the traveler to slide on the ring flange in a stable state.

Conventionally, there are two types of raising / lowering methods for the anti-node ring: one for raising / lowering the anti-node ring integrally with the ring rail (integrated raising / lowering method), and one for raising / lowering independently of the ring rail. In the integrated lifting method, the anti-node ring is fixed to the ring rail via the bracket. As an antinode ring that can be raised and lowered independently of the ring rail, Japanese Patent Laid-Open No. 63-303131 discloses that the antinode ring support member is raised and lowered integrally with the lappet angle until a predetermined winding amount is reached. After that, a device for raising and lowering integrally with the ring rail is disclosed. Further, Japanese Patent Application Laid-Open No. 3-27130 discloses a device provided with two line shafts for independently elevating and lowering a ring rail, a lappet angle and an anti-node ring.

[0004]

If the lift length is relatively short, there is no problem with the integrated lifting system. However, when a long bobbin is used to increase the lift length, there is a problem that it is difficult to properly perform balloon control in the entire range of the lift length by the integral lifting method. That is, if the anti-node ring is installed at a position suitable for the beginning of winding of the balloon, which is likely to collapse, the position of the anti-node ring after the middle ball is too high than the position suitable for proper balloon control.

Further, in the device disclosed in Japanese Patent Laid-Open No. 63-303131, the anti-node ring moves up and down integrally with the ring rail after reaching the predetermined winding amount, so that the anti-node ring approaches the winding end time. There is a problem that the distance between the node ring and the lappet may be smaller than the proper state.

Further, the device described in Japanese Patent Laid-Open No. 3-27130 needs to be provided with two line shafts, resulting in a complicated structure. In addition, there is a problem that it takes time and effort to mount it on an existing machine base.

The present invention has been made in view of the above problems, and its object is to raise and lower the anti-node ring independently of the ring rail and at an appropriate position from the start to the end of winding with a simple structure. An object is to provide an anti-node ring lifting device for a spinning machine.

[0008]

In order to achieve the above object, according to the invention of claim 1, in a spinning machine provided with a ring rail and a lappet angle, a longitudinal direction at a substantially intermediate position between the ring rail and the lappet angle. A support member disposed on the support member, an anti-node ring fixed to the support member at a predetermined interval, a rotating body rotatably disposed with respect to the machine frame, and any one of the ring rail and the lappet angle.

A support member which is arranged so as to extend parallel to the ring rail over substantially the entire length of the ring rail at an intermediate position between the fixed rope and the ring rail and the lappet angle, and which is supported so as to be able to move up and down through the rope. An anti-node ring fixed to the support member at a predetermined interval, a rotating body coaxially rotatable with the pulley so as to be integrally rotatable, one of a ring rail and a lappet angle, and the rotating body. And a driving means provided between the driving means and driving the rotating body so that the moving speed of the rope is proportional to the ascending / descending speed of the ring rail based on its ascending / descending movement.

Further, in the invention as set forth in claim 3, the ring rail and the lappet angle are supported by a column having a screw portion formed on a lower outer periphery thereof, and the column is rotatably arranged at a predetermined height position. A line shaft, which is supported in a state in which a screw portion is screwed into the nut body and positively rotates the nut body in forward and reverse directions, extends along the longitudinal direction of the spinning machine stand.

Further, in the invention as set forth in claim 4, the rope is a belt, and the supporting member is supported by a pillar arranged so as to be movable in the vertical direction, and is attached to a bracket fixed to a lower portion of the pillar.

The belt has a portion fixed to one of the ring rail and the lappet angle and a second end fixed to the second pulley.

[0012]

According to the first aspect of the present invention, the rotating body is driven to rotate in the forward and reverse directions by the action of the first drive means as the ring rail or the lappet angle moves up and down. Then, the second drive means is driven in accordance with the rotation of the rotating body, and the support member to which the anti-node ring is fixed is moved up and down. As a result, the anti-node ring is moved up and down in synchronization with the ring rail and independently of the ring rail.

According to the second aspect of the present invention, the rotating body is driven by the drive means to rotate in the forward and reverse directions as the ring rail or the lappet angle moves up and down. Then, the pulley is rotated integrally with the rotating body, and when the ring rail is raised, the rope whose first end is fixed to the pulley is wound around the pulley,
When the ring rail descends, the rope is paid out from the pulley. The support member to which the anti-node ring is fixed is raised when the rope is wound up and lowered when it is fed out. The moving speed of the rope is determined by the ratio of the radius of the rotating body and the radius of the pulley, and is proportional to the lifting speed of the ring rail. as a result,
The anti-node ring is moved up and down in synchronization with the ring rail and independently of the ring rail.

According to the third aspect of the present invention, the nut body is positively and positively and rotationally driven by the line shaft, and the column supporting the ring rail and the lappet angle is positively responding to the forward and reverse rotation of the nut body. Is moved up and down. And
In the same manner as described above, the rotating body is normally and reversely driven by the action of the driving means, and the anti-node ring is moved up and down in synchronization with the ring rail and independently of the ring rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment embodying the present invention will now be described with reference to FIGS.
It will be described with reference to FIG. As shown in FIG. 3, line shafts 2 are rotatably arranged along the longitudinal direction of the spinning machine stand 1 on both left and right sides (upper and lower sides in FIG. 3). Elevating units 3 are arranged on both line shafts 2 at predetermined intervals (for example, 2
One for every four weights). As shown in FIG. 1, the elevating unit 3 includes a screw gear 4 fixedly fitted to the line shaft 2 so as to be integrally rotatable, and screw portions 5a and 6a formed below the poker pillars 5 and 6 serving as columns. The nut bodies 7 and 8 are formed.

The nut bodies 7 and 8 are rotatably supported at predetermined height positions on the machine base frame 9 via brackets (not shown). The poker pillars 5 and 6 are supported by a machine frame 9 so as to be vertically movable. A screw gear 7a that meshes with the screw gear 4 is integrally formed on the nut body 7 corresponding to the poker pillar 5 having the ring rail 10 fixed to the upper end. A screw gear 7 is attached to the nut body 8 corresponding to the poker pillar 6 having the lappet angle 11 fixed to the upper end.
A screw gear 8a that meshes with a is integrally formed. The pitch of the screw parts 5a and 6a and the screw gears 7a and 8a
The number of teeth is set to a value at which the ring rail 10 and the lappet angle 11 are moved up and down at a predetermined ratio. Further, the screw portions 5a and 6a are formed in directions opposite to each other, and the poker pillars 5 and 6 move in the same direction when the nut bodies 7 and 8 rotate in directions opposite to each other. The lappet 1 with the snell wire 12 on the lappet angle 11
3 is fixed at a predetermined interval.

The line shaft 2 is connected to an output shaft 15 of a gearbox 14 for lifting drive through a coupling 16. The rotation of the front roller (neither is shown) is transmitted to the gear box 14 via a gear train. The gear box 14 is equipped with a switching mechanism (not shown) for changing the rotation direction of the line shaft 2 by the action of a pair of gear trains and an electromagnetic clutch. Then, the line shaft 2 is rotationally driven in the forward and reverse directions corresponding to the excitation and demagnetization of the pair of electromagnetic clutches, and the ring rail 10 and the lappet angle 11 are moved up and down accordingly. In addition,
These configurations are basically the same as those of the device disclosed in JP-A-2-277826.

A support shaft 17 is horizontally fixed to the machine frame 9 below the ring rail 10 in a direction orthogonal to the machine longitudinal direction. A first pulley 18 and a second pulley 19 as a rotating body are rotatably supported on the support shaft 17. Both pulleys 18 and 19 are integrally formed to constitute the rotating body of claim 1. Then, the first end of the belt 20 as a rope is fixed to the first pulley 18. Supports 21 are arranged on the machine frame 9 so as to be vertically movable at predetermined intervals. An anti-node ring rail 22 as a support member is fixed to the upper end of the column 21 so as to extend in parallel with the ring rail 10 over substantially the entire length of the ring rail 10. An anti-node ring 23 is fixed to the anti-node ring rail 22 at a position corresponding to the lappet 13. A bracket 24 is fixed to the lower portion of the column 21, and the second end of the belt 20 is fixed to the bracket 24. That is, the antinode ring rail 22 includes the belt 20 and the bracket 2.
It is supported so as to be able to move up and down via 4 and the column 21. The belt 20, the bracket 24, and the support column 21 constitute the second drive means of claim 1.

The column 21 is an antinode ring rail 2
2 is formed in such a length that it can move up and down within a predetermined range at an intermediate position between the ring rail 10 and the lappet angle 11. The first pulley 18 is formed such that the outer circumference thereof is longer than the length of the ascending / descending range of the anti-node ring rail 22. That is, when the belt 20 is wound around the first pulley 18 as the first pulley 18 rotates, the belt 20 is not wound more than one turn, and the first pulley 1
The rotation amount of 8 and the winding amount or the feeding amount of the belt 20 are proportional to each other.

A first end of a belt 25 as a driving means is fixedly attached to the lappet angle 11, and a second end of the belt 25 is fixed.
The end portion is fixed to the second pulley 19. Belt 25
Is wound around the second pulley 19 in the direction opposite to the belt 20. The second pulley 19 is formed so that the outer circumference thereof is longer than the length of the ascending / descending range of the lappet angle 11. That is, like the first pulley 18,
The amount of rotation of the second pulley 19 is proportional to the amount of winding or unwinding of the belt 25. First
The pulley 18 and the second pulley 19 are formed such that the ratio of the diameters thereof becomes a predetermined value such that the anti-node ring rail 22 moves up and down by a predetermined lifting amount larger than the lifting amount of the lappet angle 11. . The belt 25 constitutes the first driving means of claim 1.

The lappet angle 11, the pulley 18,
The antinode ring elevating device 26 is constituted by 19, the belts 20 and 25, the support column 21, the antinode ring rail 22 and the bracket 24. The number of the anti-node ring lifting devices 26 is the same as that of the lifting units 3 or twice the number thereof. Anti-node ring lifting device 26
Since the drive source thereof is the lappet angle 11 and there are almost no restrictions on the arrangement positions of both pulleys 18 and 19, it can be added to the existing machine base relatively easily.

Next, the operation of the device configured as described above will be described. When the spinning machine stand 1 is operated, the line shaft 2 is rotationally driven in the forward and reverse directions at a predetermined cycle via the front roller and the gear box 14. By the forward and reverse rotation of the line shaft 2, the nut body 7, via the screw gears 4, 7a, 8a,
8 are rotated in opposite directions. Then, the poker pillars 5 and 6 screwed into the nut bodies 7 and 8 are synchronously moved up or down, and the ring rail 10 and the lappet angle 11 are synchronously moved up and down.

When the lappet angle 11 rises, the second pulley 19 is rotated together with the first pulley 18 in the direction in which the first pulley 18 winds the belt 20. As a result, the antinode ring rail 22 is lifted together with the support column 21 supported by the belt 20. When the lappet angle 11 descends, the first end of the belt 25 descends together with the lappet angle 11. The first pulley 18 is urged in the direction in which the belt 20 is fed out via the belt 20 by its own weight such as the column 21 and the anti-node ring rail 22. Therefore, as the lappet angle 11 is lowered, both pulleys 18 and 19 are rotated counterclockwise in FIG. 1, and the belt 25 is wound around the second pulley 19.
Further, the belt 20 is paid out, and the antinode ring rail 22 is lowered in synchronization with the ring rail 10 and the lappet angle 11.

Ring rail 10 and lappet angle 1
The ratio of the lifting amount of 1 is determined by the pitch of the screw portions 5a and 6a, and the lifting amount of the anti-node ring rail 22 is determined by the ratio of the radii of both pulleys 18 and 19. As shown in FIG. 4, the anti-node ring rail 22 includes the ring rail 10 and the lappet angle 1 from the start to the end of winding.
It is moved up and down at the intermediate position of 1, and with a proper gap between the anti-node ring 23 and the lappet 13. In addition,
In FIG. 4, the position of the anti-node ring 23 at the start of winding is shown by a solid line, and the position at the end is shown by a chain line.

Further, in this embodiment, the ring rail 10 and the lappet angle 11 are supported by the poker pillars 5 and 6 having the screw portions 5a and 6a screwed into the nut bodies 7 and 8, respectively. Since the nut bodies 7 and 8 are positively and positively and rotationally driven via the line shaft 2, the ring rail 10 and the lappet angle 11 are stably moved during the ascent and descent. As a result, the anti-node ring 23 whose drive source is the lappet angle 11 is also vertically moved in a stable state. In addition, since both pulleys 18 and 19 are arranged below the ascending / descending range (winding position of the yarn) of the ring rail 10, it is easy to secure an installation space.

The present invention is not limited to the above embodiment, but may be embodied as follows, for example. (1) The ring rail 10 is used as the drive source of the anti-node ring lifting device 26. In this case, the first end of the belt 25 is fixed to the ring rail 10. In addition, the diameter of the second pulley 19 is formed larger than the diameter of the first pulley 18 in order to make the amount of vertical movement of the anti-node ring 23 once smaller than the chase length of the ring rail 10. Both pulleys 18,
The ratio of the diameters of 19 is set so that the ascending / descending speed of the anti-node ring rail 22 is reduced at a predetermined ratio with respect to the ascending / descending speed of the ring rail 10. In this case as well, the same operational effects as those of the above-mentioned embodiment are exhibited.

(2) Instead of the structure using the line shaft 2 and the nut bodies 7 and 8 as a device for moving the ring rail 10 and the lappet angle 11 up and down, a known lifting device using a heart cam may be used. Good.

(3) It is also possible to separate the drive of the line shaft 2 from the side of the front roller, and to drive the line shaft 2 to rotate forward and backward by a servo motor driven via a servo driver. Further, the input from the front roller side and the input of the variable motor may be combined by a differential device to be the drive output of the line shaft 2. Further, the line shaft 2 may be provided with a screw gear 4 that meshes with both the screw gears 7a and 8a.

(4) As shown in FIG. 5, the second pulley 1
In place of 9, the pinion 27 as a rotating body is provided so as to be integrally rotatable with the first pulley 18, and the rack 2 as a driving means is provided.
8 is fixed to the ring rail 10 so as to be movable together with the pinion 27. Illustration of the lappet angle 11 is omitted in the figure. In this case, the pinion 27 is positively rotated via the rack 28 as the ring rail 10 moves up and down. Therefore, even if the anti-node ring rails 22 and columns 21 are made of a light material,
The first pulley 18 is moved up and down while being surely synchronized with the ring rail 10 and the lappet angle 11. The rack 28 may be fixed to the lappet angle 11. In that case, as the pinion 27, one having a diameter smaller than that of the first pulley 18 is used.

(5) Both pulleys 18 and 19 may be arranged at positions corresponding to the ascending / descending range of the ring rail 10. or,
The support shaft 17 may be arranged parallel to the longitudinal direction of the spinning machine base 1. (6) Instead of driving the anti-node ring 23 in proportion to the lifting speed of the ring rail, the lifting speed of the anti-node ring 23 is changed during winding in accordance with the spinning conditions. Good. For example, instead of the first pulley 18 having a constant distance from the center of the support shaft 17 to the outer peripheral surface, a pulley having a shape in which the distance from the center of the support shaft 17 to the outer peripheral surface is changed is used. The circular pulley may be eccentrically supported on the support shaft so as to rotate integrally with the second pulley 19. Further, the second pulley 19 side instead of the first pulley 18 may have a similar configuration.

(7) Two rotating bodies having different diameters are integrally rotatably fixed to a rotating shaft rotatably supported by the machine base frame 9, and the second rotating body, the ring rail 10 and the lappet are fixed. One of the angles 11 and the first such as a belt
Alternatively, the first rotating body and the anti-node ring rail 22 may be connected by a second driving means such as a belt. In this case, the rotating body may be a pinion and the driving means may be a rack. Either the first rotating body or the second rotating body may be a pinion, or both rotating bodies may be a pinion. The drive means corresponding to the pinion is a rack.

In the present specification, the rope and the pulley are used in the following meanings. A rope is a flat belt, a V-belt, a round belt, a chain, a chain, a toothed belt, a tape, a rope, a cord, or the like that can be freely bent and is wound around a pulley in an arc shape.

Pulley: A pulley means a rotatable guide member such as a pulley, a roller, a sprocket, and a toothed pulley, around which the rope can be wound in a substantially arc shape. The technical ideas other than the invention described in the claims that can be understood from the embodiments and the modified examples will be described below together with the effects thereof.

(1) In the invention described in claim 2, the rotating body is a gear formed so that a ratio of the pulley and its diameter becomes a predetermined value, and the drive means is meshed with the gear. A rack fixed to either the ring rail or lappet angle. In this case, even if the supporting member (anti-node ring rail) or the like is made of a light material, the pulley is driven to rotate reliably in synchronization with the ring rail and the lappet angle, and the anti-node ring is stably moved up and down. .

[0036]

As described above in detail, the first and second aspects are provided.
According to the invention described in claim 4, the anti-node ring can be lifted and lowered at a proper position independently of the ring rail from the start to the end of winding with a simple structure. According to the third aspect of the invention, the anti-node ring is further moved up and down in a stable state.
