Description

Description: TECHNICAL FIELD The present invention relates to a spinning winder that winds a spinning yarn spun from a spinning machine at high speed, and in particular, a bobbin holder protruding from a turret plate at the time of yarn switching. The present invention relates to a turret-type spinning winder that rotates.

[Conventional technology]

This type of conventional take-up winder is shown in FIGS. 5 (side view) and 6
A description will be given based on the figure (front view). This spinning winder 1 comprises a turret plate 4 which is rotated by 180 ° about a horizontal axis 3 relative to a main body frame 2, two bobbin holders 5 and 6 which are cantilevered from the turret plate 4, and a turret. Induction motors 7 and 8 fixed to the back side of the plate 4 for rotating and driving the bobbin holders 5 and 6, and a touch roller 10 provided on an elevating frame 9 vertically movable with respect to the main body frame 2, The lifting frame 9 is mainly composed of a traverse device 11 provided on the lifting frame 9, and the lifting frame 9 is supported by a contact pressure cylinder 12 provided on the base end side thereof to support the entire weight of the lifting member and the contact pressure cylinder 12. The pressure difference from the lifting force of the touch roller 10
The contact pressure is applied to the package.
In addition, B is a bobbin, P is a package wound around the bobbin B, and 13 is a pusher device for pushing out the bobbin B of the full package P.

The operation of the above-described spin winding machine will be described below. In FIG. 5, the bobbin holder 5 is in the winding position a, and the bobbin holder 6 is in the standby position b. When the package at the winding position a is fully wound, the turret plate 4 turns 180 °, the fully wound package P becomes the standby position, and the empty bobbin B becomes the winding position. Then, as shown in FIG. 6, the yarn Y
While being in contact with the bobbin B, the bobbin B is wound into the full winding package P, and the yarn Y is transferred from the full winding package P to the bobbin B by a yarn passing device (not shown). Next, the rotation of the bobbin holder 6 at the standby position is stopped, the pusher device 13 pushes the full-winding package P onto a doffing dolly (not shown), and at the same time, an empty bobbin B is inserted into the bobbin holder 6. By repeating the above operation, the yarn is continuously wound.

[Problems to be Solved by the Invention]

By the way, the bobbin holders 5 and 6 are cantilever-supported rotating bodies, and further, hold a package P of a considerable weight wound around the bobbin B and provide a predetermined contact pressure with a touch roller.
The structure is loaded via 10. Furthermore, in recent years, a high-speed winding of 3000 m / min or more is common in a spinning winder, the bobbin holders 5 and 6 thereof are gradually lengthened, and a 1200 mm bobbin holder is also put into practical use. In addition, the trend toward longer bobbin holders continues, and 1600 mm bobbin holders are also being considered. However, when the length is 1600 mm, the cantilever type bobbin holder described with reference to FIGS. 5 and 6 is structurally unreasonable. Therefore, it has been proposed that the bobbin holder at the winding position is supported on both sides, and when the yarn is switched, the bobbin holder is cantilevered so that the turret plate turns. However, as described above, the bobbin holder is rotating at a high speed even when the yarn is switched, and there is a problem that vibration and the like caused by structural oversight due to the lengthening of the bobbin holder are generated when the yarn is switched. As a result, the mechanical life is shortened due to increased mechanical vibration,
There is a possibility that the inner layer yarn may be damaged due to the collapse of the end face of the full-wound package, the promotion of Kikumaki, and the transmission of vibration to the bobbin holder at the winding position.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to enable the bobbin holder to be held at both ends even when the thread is switched and to increase the length of the bobbin holder. It is intended to provide a winding machine.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a spinning winder according to the present invention has a turret plate which is swiveled around a swivel shaft provided on one side of a main body frame, and a turret plate which is provided on the turret plate.
In a take-up winder equipped with two bobbin holders projecting in a cantilever manner along a rotary shaft of a book and positioned alternately at a take-up position and a standby position by turning of a turret plate. A bobbin holder is provided with a first arm that is detachably supported at both ends thereof and has both ends thereof coaxially with the swivel axis of the turret plate. The first arm is supported and the first arm is provided with the rotary shaft at the winding position. A second arm that swings about the main body is provided on the other side of the main body frame side so that the first arm can swivel with respect to the swivel axis or swing with respect to the rotary shaft in the winding position. It is adapted to be supported by the second arm.

[Action]

The bobbin holder in the winding position is supported by a turret plate on one side of the main body frame and a first arm on the other side of the main body frame, both ends of which are supported along the rotation axis. When a full-winding package is formed on the bobbin holder at the winding position and the yarn transfer is performed between the bobbin holder at the standby position and the empty bobbin, the turret plate and the first arm have a coaxial rotation axis. Even so, the winding position and the standby position are switched while the two bobbin holders are held on both sides. Then, the bobbin holder of the full-winding package that has been switched to the standby position is held on both sides until the rotation is stopped. Next, when pulling out the full-wrapped package from the bobbin holder at the standby position, the first arm is detachable from the bobbin holder distal end side and is swingable about the rotation shaft at the winding position. The engagement is released, and then the full package is retracted to a position where it does not hinder the pushing out, but the bobbin holder at the winding position is supported by both ends.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of the take-up winder of the present invention, and FIG. 2 is a front view of the take-up winder of the present invention. In FIGS. 1 and 2, the same reference numerals are given to the parts that operate in the same manner as in FIGS. 5 and 6, and the description thereof will be omitted.

The bobbin holder is different from those shown in FIGS. 5 and 6.
It is the support structure of the tip of 5,6. Hereinafter, this support structure will be described in detail.

1 and 2, the bottom end 2A of the body frame
A gate-shaped frame 20 is erected on. A second arm 21 is swingably supported by the portal frame 20, and a first arm 22 is swingably supported by the second arm.

Next, details of the structure of the first arm 22 and the second arm 21 will be described with reference to FIGS. 3 and 4.

The first arm 22 has a bearing box 23 at its center and cylinders 24 equidistant from both ends thereof. A piston 25 is slidably fitted in the cylinder 24. A cone 26 is press-fitted into the piston 25, and a support shaft is provided in the tip of the cone 26.
The bearing 27 is rotatably supported by the bearing 28. Support shaft 27
Has a conical tip, and the bobbin holder 6 has a conical hole.
Engage with 6a. The cylinder 24 and the piston 25 described above constitute a pneumatic actuator, and when compressed air is introduced into the c port, the piston 25 retreats and the bobbin holder 6 and the support shaft 27 are disengaged. When compressed air is introduced into the d port, the piston 25 advances and engages the bobbin holder 6 with the support shaft 27. In this way, the support shaft 27 is rotatable and disengageable with respect to the bobbin holder. The turning center of the first arm 22 is coaxial with the horizontal shaft 31 shown in the first illustration.

The second arm 21 has one end bearing on the bearing box 23 of the first arm 22.
It has a shaft 30 fitted through 29 and a bearing box 31 at the other end. The bearing box 31 is swingably supported via a bearing 33 that is press-fitted into a cylinder 32 fixed to the gate frame 20. In order to control the swing angle of the second arm 21, a pinion 34 is press-fitted into the outer circumference of the bearing box 31, and a rack 36 attached to the tip of the cylinder device 35 meshes with the pinion 34. After all, the second arm 21 is swingably supported by the gate-shaped frame 20 following the bottom end 2A of the main body frame, and the first arm 22 is swingably supported by the second arm 21. The pivot center of the second arm 21 is coaxial with the bobbin holder 5.

As clearly shown in FIG. 3, one of the cylinders 24 of the first arm 22 is located at the winding position a and the other is located at the standby position b. The bearing box 23 of the first arm 22 is located at the center O of rotation of the turret plate. Therefore, the engagement between the bobbin holder at the standby position b and the first arm 22 is released,
When the cylinder device 35 is advanced, the rack 36 and the pinion 34
The second arm 21 swings to the position indicated by a chain double-dashed line about the winding position a by the meshing of. In this swinging state, the first arm 22 and the second arm 21 are in positions where they do not interfere with the pushing out of the full package P.

By the way, since the bobbin holder that rotates at a high speed is in the winding position for a long time, a structure for surely supporting both ends of the bobbin holder 5 at the winding position will be described with reference to FIG.
The cylinder 32 fixed to the portal frame 20 has a piston
37 is slidably inserted. An engaging hole 39 formed by a bearing 38 is provided at the tip of the piston 37, and a small diameter portion 24a at the rear end of the cylinder 24 of the first arm 22 is fitted into the engaging hole 39. The cylinder 32 and the piston 37 described above constitute a pneumatic actuator, and when compressed air is introduced into the e port, the piston 37 retreats, and the small diameter portion 24a and the engagement hole 39 are disengaged. When compressed air is introduced into the f port, the piston 37 advances and the small diameter portion 24a and the engagement hole 3
9 and engage. Thus, the first position at the winding position a
The cylinder 24 of the arm 22 is linearly supported by the portal frame 20 via the piston 37 of the second arm 21 and the cylinder 32. Therefore, the bobbin holder 5 at the winding position a
The rigidity of both-sided support increases. It is preferable to use a known chuck means instead of the bearing 38 at the tip of the piston 37. The chuck means can perform reliable engagement while maintaining parallelism, as compared with the case of using parallel holes or taper pin engagement.

Next, the operation of the above-described spinning winder will be described with reference to FIGS. 1 and 2.

First, in FIG. 1 and FIG. 2, when a full winding package is formed at the winding position a, the cylinder 24 and the piston are
The engagement of 37 is released, the turret plate 4 turns (moves),
The full winding package P becomes the standby position b, the empty bobbin B becomes the winding position a, and comes into rolling contact with the touch roller 10, and the yarn winding from the full winding package P to the empty bobbin B is performed. Simultaneously with the operation, the first arm 22 supporting both ends of the bobbin holders 5 and 6 also pivots about the same horizontal shaft 3 (the engagement between the cylinder 24 and the piston 37 is released). After the rotation of the first arm 22 is completed, the cylinder 24 and the piston 37 are engaged again, and the bobbin holder 5 at the winding position a is securely supported by both ends. After the yarn transfer is completed, the induction motor 8 is brought into a braking state and the bobbin holder 6 at the standby position b is decelerated. Even in this decelerated state, the bobbin holder 6 remains supported on both sides. When the deceleration is completed and stopped, the support shaft 27 and the bobbin holder 6 are disengaged (see the solid line state in FIG. 4). Next, the second arm 21 swings in the direction around the winding position a. That is, the first arm 22 and the second arm 21 are retracted to the two-dot chain line position that does not hinder the axial pushing of the full package P. However, the both-end support of the bobbin holder 5 at the winding position a is still maintained. Then, the pusher device 13 pushes the full-roll package P to an automatic doffing device (not shown) or the like (operation). Instead, when the empty bobbin B is inserted into the bobbin holder 6, the second arm 21 swings in the direction around the winding position a ,. The support shaft 27 and the bobbin holder 6 are engaged again to prepare for the next thread switching.

As described above, the bobbin holders 5 and 6 remain supported by both ends except when the full package P is pushed out, and the bobbin holders 5 and 6 are supported by both ends during high speed rotation. The control of the operation timing of the actuator formed by the cylinder and the piston and the cylinder device is performed by the electromagnetic valve device 19 that operates based on a command from the controller 18 such as the induction motor 8.

The above embodiment is a bobbin holder for mounting the bobbin B.
Although the so-called spindle drive type take-up winder in which 5, 6 are directly driven by the built-in motor 8 has been described, the bobbin B is indirectly driven by driving the touch roller rolling on the bobbin B mounted on the bobbin holder. It is also applied to a so-called friction drive type take-up winder.

〔The invention's effect〕

The spinning winder according to the present invention is a turret-type spinning winder in which two bobbin holders are cantilevered on a rotatable turret plate on one side of the main body frame. With the first and second arms, the bobbin holder in the winding position is constantly held in both directions, and the bobbin holder in the standby position can also be held in both directions until the rotation is stopped. This hinders the yarn passing operation from the full winding package to the empty bobbin. Since it is not provided, there is an effect that it is possible to take measures against vibration by lengthening the bobbin holder or the like at all stages of winding.
