JP2000289938A - Grasping device of linear body used in winding of linear body on reel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To automate and ensure the winding of the end of a linear body on a reel in the winding of the linear body on the reel by forming a clearance capable of inserting the linear body between nipping members when one nipping member is pressed against a spring acting in the direction of closing the clearance between the nipping members. SOLUTION: One nipping member 18a is pressed against a spring arranged between a pair of nipping members 18a and 18b to open the nipping members 18a and 18b. The insertion of a linear body 14 to the resulting space is performed (the taking out thereof is allowed). The linear body 14 is grasped between the nipping members 18a and 18b by the restoring force of the spring. When the relative positions of a grasping device 18 and the guide pulley of a traverser 20 are separated in the axial direction of a reel 12, the linear body 14 can be spirally wound on a reel drum part 12a by rotating a disc 16 about the axial line X of the reel 12 since the linear body 14 is shifted to the disc 16 side.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically winding an end of a filament made of an organic or inorganic material on a reel, and holding the filament.

[0002]

2. Description of the Related Art In the production of a filament, for example, when it is difficult to continuously perform two processes having greatly different production speeds, such as a heat treatment process and a wire drawing treatment process, the reel is temporarily wound around a reel. Usually, it is taken out and then subjected to the next step.

[0003] For this reason, conventionally, in order to wind the umbilical member on a reel, a winding start end is fixed by a stopper attached to the reel, and a loop is formed on the winding start end. Formed and wound on a reel, the winding end of the filament is fixed to the reel by passing through the loop, and furthermore, between the flange portion of the reel and the driving device for rotating the reel. Methods such as pinching have been performed.

[0004]

However, since any prior art requires manual winding work, it is ensured that the end of the filament is securely wound around the reel. It was difficult to do so, and there were problems such as the striatum coming apart. Further, it is a problem to be solved when automating a production line in order to cope with the recent labor shortage.

The present invention has been made in view of the above problems, and provides a gripping device useful for automatically and reliably winding the end of a striated body on a reel when winding the striated body on the reel. The purpose is to:

[0006]

That is, the present invention relates to a method for gripping an end portion of a filament and winding the filament in a helical shape on a reel, and then moving the filament in a reel direction. In a device for gripping an end portion of a striated body by winding the striated body around a reel, a spring acting between a pair of clamping members in a direction to close a gap between the clamping members. And a gap for inserting the striated body between the holding members when one of the holding members is pressed against the spring.

[0007] By using the gripping device of the present invention,
When the striated body is moved in the width direction of the reel and overlapped with the already wound part and wound, the end of the striated body can be surely gripped. The relative movement between the filament and the reel is restrained by tightening the filament wound on the reel, and the end of the filament can be securely wound on the reel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIGS. 1A and 1B are a front view and a side view schematically showing a winding device 10 to which the gripping device of the present invention is applied. The reel 12 is rotatably driven around its axis (X) by a known suitable driving device (not shown), and is separated between the opposed flange portions 12b in the direction of the axis (X). It functions to wind the striated body 14 around the portion 12a.

The disk 16 disposed adjacent to the reel 12 in the axial direction is substantially coaxial with the reel axis (X), and is also formed by a known suitable driving device (not shown). It can rotate relative to the reel 12.

[0010] A gripping device 18 capable of gripping the end of the striated body 14 is mounted on the disk 16 so as to be spaced radially outward from the reel 12. Therefore, the gripper 18 can rotate about the axis (X) of the reel 12. Further, the gripping device 18 can grip and release the end of the striated body 14 as required, and the configuration of the device will be described in detail with reference to FIG. That is, a pair of holding members
A spring 18c is arranged between 18a and 18b, and one of the holding members 18a is pressed against the spring to open a pair of holding members, and the insertion or insertion of the wire body 14 therebetween. Of the striatum due to the restoring force of the spring 18c
14 can be gripped between the pair of holding members.

The winding device 10 also includes a traverser 20 disposed opposite the reel 12 via a gripping device 18.
The traverser 20 engages the striated body 14 to move the striated body to the reel 12.
It functions as a guide to guide in the width direction of
The illustrated traverser 20 has a guide pulley 20a,
As shown by, it reciprocates at a distance substantially parallel to the axis of the reel 12. Of course, the traverser is not limited to the one shown in the illustrated example.
What is necessary is just to be able to reciprocate in 12 axial directions.

Next, the manner in which the filament 14 is automatically wound around the reel 12 will be described below. The striatum 14 is shown in FIG.
As shown in FIG. 2A, it is assumed that the traverser 20 is previously sandwiched and fixed to a sandwiching member of a gripping device 18 attached to the disk 16 via a guide pulley 20a of the traverser 20. At this time, the end of the striated body 14 is in a relative positional relationship between the gripping member and the guide pulley 20a in the reel axis direction, that is, as shown, the gripping device 18 and the guide pulley 20 of the traverser 20.
a is shifted toward the disk 16 by separating the relative position from the reel a in the axial direction of the reel. It can be wound in a helical shape around the portion 12a. Of course, as shown in FIG. 2 (b), while rotating the disc 16 around the axis (X) of the reel 12 in the direction indicated by the symbol B, the direction in which the traverser 20 is separated from the disc 16;
That is, the linear body 14 can be wound in a helical shape around the body 12a of the reel also by moving in the direction shown by the arrow (C).

In either case, the reel 12 can be immovable with respect to the rotational movement of the disk 16, but when the reel 12 is immovable, the wire is wound around the filament 14 when wound around the reel 12. Since tension is applied to the strip, slip frictional resistance is generated between the strip 14 and the reel, which may cause a problem in the wound strip.
It is also preferable that the disk 16 is also rotated integrally with the disk 16 in the same direction. In the illustrated example, the guide pulley 20a of the traverser 20 is used when the winding of the filament 14 onto the reel 12 is started.
Is positioned further away from the holding member of the holding device 18 with respect to the disk 16, the winding of the striated body 14 around the holding device 18 due to the rotation of the disk 16 can be significantly avoided.

When the filament 14 has been wound on the reel 12 a predetermined number of times, as shown in FIG.
The traverser 20 is moved in the direction shown by the arrow (D) while rotating the traverser 20 in the direction shown by the symbol B, preferably integrally with the reel 12, so that the striated body 14 is wound around the reel 12.
It is superimposed on the winding part of 14 and wound.

As a result, as shown in FIG. 3 (b), the wire body 14 wound in an overlapping manner is gradually wound while pressing the lower winding portion against the body of the reel. This restricts the relative movement of the end of the striatum to the reel.
Therefore, the lower part of the superposed and wound filaments 14, that is, the ends of the filaments, can be automatically wound on the reel 12. Then, when the winding of the end of the striated body 14 onto the reel 12 is completely completed, the gripping device 18 is opened as shown in FIG. Release the ends.

In this case, the wound portion of the end of the filament wound around the reel 12, that is, the wound portion of the filament located on the reel side, is superimposed on the wound portion and located above the wound portion. Although the winding part is slightly different depending on the material of the striated body, there are at least three or more overlapping parts, and the interval between the overlapping parts, that is, the overlapping pitch, is at least three times the diameter of the striated body. By doing so, the striated body can be almost securely wound.

Next, while the rotation of the disk 16 is stopped,
When the reel 12 is subsequently rotated in the direction indicated by the arrow, the striated body newly wound on the reel, as shown in FIG. As a result, the striated body is gradually wound in a helical shape while being wound around the released end of the striated body.

In the apparatus shown in FIG.
And the reel 12 is rotated about a coaxial axis (X), but the linear body 14 guided through the traverser 20 is
May be rotated about the axis of the reel 12, and the end of the striatum may be wound around the reel. Further, when the gripping device 18 is mounted on the flange portion 12b of the reel 12 so as to be able to advance and retreat in the axial direction of the reel, and when the striated body is wound around the reel, the gripping device is separated substantially in parallel to the reel axis to remove the body. The end of the striated body is gripped while projecting in the direction of the portion 12a, and when the winding of the end of the striated body is completed, the gripping device is retracted, and subsequently, the striated body is wound on a reel It is also possible to adopt a configuration in which picking is performed without obstructing picking.

[0019]

As described above, according to the present invention, the end of the striatum can be reliably gripped by the gripping device.
By reciprocating the striated body in the width direction of the reel, and overlapping and winding the striated body, the striated body can be automatically and reliably wound on the reel. There is no need to perform a winding operation, so that the reliability of the operation can be improved, and the operation rate of the winding device can be improved.
