Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding device for a linear body wound on a reel.

Conventionally, when a linear body wound around a reel is fed out in a heat treatment process or a plating process, there are a flyer method and a reel rotation method. However, in the flyer system, the position of the guide roller of the flyer that rotates around the reel rotates in the same plane across the width of the reel, resulting in fluctuations in the payout tension and defects in the twisted iodine.

In addition, the reel rotation method has the disadvantage that the reel must be lifted and set on the rotating shaft, which requires time and effort to set the reel.

The present invention eliminates the above-mentioned drawbacks of the prior art, and provides a device that facilitates setting of the reel and feeds out a linear body with stable tension.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a plan view of a linear object feeding device showing an embodiment of the present invention, and FIG. 2 is a front view of the same, in which a large number of rollers 2 are mounted on the upper part of a main body 1 of a machine base having a required length and width. , 2... are arranged rotatably at equal or unequal intervals, and the bearing 3 is positioned below the roller and the axis of the bearing 3 is between the rollers 2 and 2. It is fixed to the bottom of the main body 1 with bolts or the like. This bearing 3 rotatably supports a lower shaft 4 having a hollow portion in the upper part, and a reel 6 around which a linear body is wound around the upper shaft 5 placed on a roller 2.
It penetrates through the shaft hole 7, fits into the hollow part of the lower shaft 4, and is fixed with a key.

Further, a dancer arm 11 and a brake wheel 12 which are rotatable about the lower shaft are attached to the lower part of the lower shaft 4 which projects downward from the bearing 3, and a dancer roller 13 is provided on the dancer arm 11. Further, a band 14 having one end fixed to the main body 1 and the other end attached to the dancer arm 11 is stretched around the outer periphery of the brake wheel 12.

Next, an arm 9 having grips 8, 8 is attached to the upper part of the upper shaft 5 which is fitted and fixed to the center part of the lower shaft 4, and a tightening jig 10 is screwed to the lower part of this arm to lift the reel. Configure the jig for use.

Further, a small hole-shaped locking portion 15 is provided at a required position on the upper end surface of the reel 6 to engage with the lower end of the grips 8, 8 of the reel lifting jig.

Furthermore, the tightening jig 10 constituting the reel lifting jig
can be provided at the upper or lower part of the arm 9 having the handle, and by rotating the tightening jig 10, the arm 9 having the handle can be moved up and down.

A method of feeding out a linear body using the above-mentioned feeding device will be described below.

A reel 6 wound with a linear body is placed on the roller 2 from a transport truck or the like, and is slid onto the roller to a position on the axis of the bearing 3 and stopped.

Incidentally, at this time, a positioning stopper may be provided at the upper end of the main body 1 so that the reel is stopped at a predetermined position by this stopper.

Next, the upper shaft 5, which has a reel lifting jig attached to its upper part, passes through the shaft hole 7 of the reel, fits into the hollow part of the lower shaft 4, and is fixed with a key. Furthermore, the lower ends of the handles 8, 8 of the reel lifting jig are inserted into the locking portions 15 provided on the upper end surface of the reel and engaged by slightly rotating the arm 9. Then, by rotating the tightening jig 10, the reel 6 is lifted (floated) above the roller 2, and in this state, the linear body is let out via the dancer roller 13. A constant extending force is applied to this linear body by a brake wheel 12 and a band 14 attached to the lower shaft 4.

Therefore, by having the above configuration, the present invention has the following features:
Since the reel can be moved by sliding it on the rollers in a tilted state from the transport cart, the reel can be set in a predetermined device extremely easily, the work can be carried out safely, and the work time can be shortened. Also, unlike the flyer system, this invention has excellent effects such as being able to stabilize the feeding force because the reel can be fed out while rotating.
