Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a tape winding device used for winding various tapes onto a wire such as a stranded wire, which is, for example, a cable core.

A device has been proposed in which the tape is alternately fed out from two tape storage reels and the tape is continuously wound onto a running wire (see Japanese Patent Laid-Open No. 58-47776). This tape winding device comprises: - a hollow shaft rotatably supported by a pair of support frames, through which a wire to be wound with tape passes;

A rotary drive source that rotates this hollow shaft, two tape storage reels installed on the hollow shaft so as to rotate independently, and two tape storage reels installed on the hollow shaft so as to rotate together with the corresponding tape storage reels. two flyers having kite rolls which are attached to the respective tape storage reels and guide the tapes unwound from the corresponding tape storage reels into the hollow shafts through the introduction holes of the hollow shafts;

The two wheels are rotated alternately from the drive source through the 11-stage flanch! ;7] The replacement mechanism and the tape fed out from the tape storage reel ((
It consists of a tension force (=I) applying means for applying the U force, and several tape guides that are cut into the hollow shaft and guide the tape inside the hollow shaft so that it is wound around the wire led out from the hollow shaft. .

In this conventional technology, since the switching mechanism is provided on the hollow shaft, it was only possible to wrap a large diameter wire with tape by receiving the outer part of the hollow shaft. Since the tension control means were disposed inside the pair of support frames, there was a drawback that maintenance and replacement of the belt and flange was troublesome.

The first object of the present invention is that the outer diameter of the hollow shaft can be increased so that it can be applied to various wire rods, and it also facilitates maintenance of the J base mechanism and tensioning means and replacement of parts. The purpose of the present invention is to provide a tape-wrapping space between the folds.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 schematically shows a tape winding device 10 of the present invention.

Two flyers 22 and 22' having tape guides such as kite rolls 20 and 20' guided into the hollow shaft 16 through the introduction hole 16a of the hollow shaft 16, rotatably supported by the auxiliary frame 12°' It consists of a tape kite holder 24 that guides the inner tape 2 so as to be wound around the wire l led out from the hollow shaft. The tape 2 is fed out from one of the tape storage reels 18 or 18' as the corresponding flyer 22 or 22'' rotates.

and a pulley/belt means 38 for transmitting power to.

As shown in FIG. 2, the fryer 22, 22' includes a support cylinder 4 rotatably mounted on a hollow shaft 16 by a bearing 40.
A switching mechanism 44 fixed to the flyer 2 and switching the rotation of the fryers 22 and 22' is supported by electromagnetic clutch means 46 and 46' that extracts driving force from the drive shaft 36 of the rotary drive source 32 and the electromagnetic clutch means 46 and 46°. It consists of pulley belt means 48, 48'' for transmitting power to the cylinder 42.

In FIG. 2, reference numerals 50 and 52 indicate tighteners that apply tension to the pulleys of the pulley φ belt means 38, 48, and 48'.

As shown in FIG. 2, the tape storage reels 18 and 18' are identified by a support tube 56 that is rotatably supported by a support tube 42 by a bearing 54.

can be easily removed. Incidentally, on the tape kite holder 24 side, the belt can be easily submerged by removing the single support par 24a.

To roughly describe the operation of the tape winding +1 device 10 of the present invention, if the tape 2 is being taken out from the tape storage reel 18' for example, the corresponding flyer 22
゛ is rotated by the engagement of the electromagnetic clutch means 46° of the switching mechanism 44, and the tension (=1) is the torque motor 6
Since it is operated by the bias of 0', the tape storage reel 1
The tape 2 is wound around the wire l from 8' through the tape kite holder 24. During this time, the tape 2 is fed to the other tape storage reel 18 by a single tape feeding stage (not shown). When winding from the tape storage reel 18' is nearing completion, the end end of the tape is connected to the start end of the tape in the other tape storage reel 18 by appropriate means not shown in FIG. At the same time as the end of feeding the tape on the ° side, the electromagnetic clutch of the switching mechanism 44 is switched from 46° to 46, and the torque motor is switched from 60' to 60, and the tape storage reel 18 is switched from 60' to 60'.
Instead of νJ, the tape 2 can be continuously wound around the wire 1.

According to the present invention, as shown in "-", the tape switching mechanism is placed outside the support frame, which facilitates its maintenance and management, and the clutch L stage required for this switching is removed from the hollow shaft. There is a practical benefit in that the tape can be wrapped around wire rods of various diameters by converting the wire into a kf type.
