Description

[Detailed description of the invention] [Industrial application field] This invention is useful when attaching a long attached body such as a shield wire to the outer periphery of a filament body such as a running power cable core. The present invention relates to a device for holding down a long appendage to a traveling linear body, which is used to press the long appendage to the above-mentioned linear body.

[Conventional technology]

For example, as shown in FIGS. 2 and 3, a large number of shield wires, etc., are attached to the outer periphery of a running filament W such as a cable core, and are fed out from reels 2 along with the filament W. When attaching the elongated attachment bodies 3..., at the attachment points of the elongated attachment bodies 3..., in order to hold these elongated attachment bodies 3... to the outer periphery of the filament body W, A device (hereinafter abbreviated as a “pressing device”) 4 for holding down the elongated attached body to the traveling linear body is provided.

As shown in FIG. 3, this holding device 4 has a main body 5 made of a plate-like member through which a filament W such as a cable core is inserted into a central opening 6. At the four corners of the main body 5, Guide reels (guiding members) 7... and moving (moving members) reels 8 are each rotatably disposed. And those guide reels 7
An endless belt 9 is stretched between ... and the moving reel 8. This endless band 9 is made of a material having a predetermined tensile strength, such as steel or plastic, and is wound several times around the outer periphery of the filament W to which the elongated attachments 3 are attached. Moreover, it is stretched across the guide reel 7 and the movable reel 8. On the other hand, the movable reel 8 is placed on the main body 5 in the direction of pulling the endless band 9 and in the direction of loosening it (pulling and loosening direction).
The endless band 9 is movably provided, and is further biased by a spring 10 in a direction to pull the endless band 9. As a result, the endless band 9 is stretched between the guide reels 7 and the movable reel 8 with a predetermined tensile force applied thereto.

The conventional holding device 4 has the following functions at the holding portions of the elongated attached body 3 shown in FIG.
It is integrally fixed to a rotary plate 12 rotatably provided on the outer periphery of the filament body W via a motor 11. Note that the reference numeral 13 in the figure indicates a separation board 14 that guides the elongated attachments 3 sent from the reel 2;
The wire body W is equipped with a drive motor 15 that alternately rotates the separating board 14 in opposite directions, for example, and runs on the elongated attached body 3 while imparting a waveform (SZ twist) to the long attached body 3. This figure shows a corrugating device to be attached to the outer circumference of the wafer.

Therefore, in the conventional holding down device 4 having the above configuration, the main body is attached to the outer circumference of the filament W which is running rightward in the figure while the elongated attached bodies 3 are attached in FIG. 5 is rotated by the motor 11 at a predetermined rotational speed, the upstream side of the endless band 9 is sequentially wrapped around the filament body W, thereby causing the elongated attached bodies 3 to be attached to the outer periphery of the filament body W. Along with this, the downstream portion of the endless band 9 that was holding down the elongated attached bodies 3 separates from the filament W and is unwound. In other words, if the endless band 9 is wound one turn on the filament body W and the elongated attached body 3 on the upstream side, one turn is unwound on the downstream side,
Even when the filament body W is traveling, it is always wound spirally around the filament body W and the elongated attached body 3 at the same position. During this period, if the outer diameter of the filamentary body W or the winding state of the endless belt 9 changes and the appropriate length (tensile force) of the endless belt 9 changes, the movable reel 8 is moved by the urging force of the spring 10. It follows this by displacing against it. As a result of the above, the long attached bodies 3 attached to the outer periphery of the filament body W are sent to the next process while being pressed against the outer periphery of the traveling filament body W, and are further attached to the outer periphery of the filament body W. The tape 16 etc. will be wound and fixed.

[Problem that the invention attempts to solve]

However, in the conventional holding device 4, since the spring 10 is directly connected to the movable reel 8, when there is a change in the outer diameter of the filament W, the spring 10 expands and contracts greatly in response to the change. However, as a result, the holding force of the endless belt 9 fluctuates significantly, making the attached state of the elongated attached bodies 3 unstable.

[Purpose of invention]

This invention was made in view of the above circumstances, and the purpose is to provide a new holding device that can always hold down the elongated attached body to the filamentous body with a uniform holding force. It is something to do.

[Means for solving problems]

The restraining device of this invention has a plurality of guide members arranged on the main body which is rotatably provided on the outer periphery of the part where the elongated attached body of the traveling filament is attached, and a plurality of guide members are arranged between the guide members. An endless belt wound around the outer periphery of the filament body to which the elongated attached body is attached is stretched, and a movable member is provided to guide the endless belt and to be movable in the direction of tensioning and loosening the endless belt. It has a structure in which a fluid pressure cylinder that biases the endless band in a direction to stretch the member is connected to the member.

[Effect]

In the holding device configured as described above, even if the movable member moves due to changes in the outer diameter of the filament, the fluid pressure cylinder is connected to the movable member, so that the force caused by the displacement of the movable member is reduced. There is little fluctuation, and tension fluctuations in the intangible band can be prevented.

〔Example〕

FIG. 1 shows an example of the holding device of this invention. At a predetermined position on the main body 21 of this holding device 20, there are a guide member 22 consisting of five sets of guide reels, and a moving member 22 consisting of a moving reel. A member 24 is provided. These guide members 22...
An endless band 26 made of a material such as steel or plastic and wound several times around the outer periphery of a filament W such as a cable core is stretched across the moving member 24 and the moving member 24.
Here, the moving member 24 is provided so as to be movable on a guide 28 attached to the main body 21 in the direction of tensioning and loosening the endless band 26. This moving member 24 includes two sets of small guide reels 2.
9, 29 and movable pulleys 30A, 30B via wires 32, 33 to a fluid pressure cylinder 34 such as a pneumatic or hydraulic cylinder.

That is, one end of the wire 32 is attached to the moving member 24, and the other end of the wire 32 is guided in sequence to the small guide reel 29, movable pulley 30A, small guide reel 29, and movable pulley 30B to the fixture 35.
is fixed. And movable pulleys 30A, 30
B are both rotatably held by a movable pulley holder 36, and this movable pulley holder 36 is further connected via a wire 33 to a fluid pressure cylinder 34 that biases the movable pulley holder 36 in a pulling direction. . Furthermore, a pressurized fluid supply pipe for the fluid pressure cylinder 34 such as compressed air or pressure oil is connected to the fluid pressure cylinder 34 from the outside of the holding device 20 via a rotary joint (not shown). is connected. As a result, the endless band 26 is stretched under a predetermined tension via the movable pulleys 30A, 30B and the moving member 24. Then, a holding device 2 having the above configuration is provided.
0 is provided rotatably in the direction of the arrow in FIG. 1 on the outer periphery of the running filament W by a rotation drive device (not shown).

However, in such a holding device 20, since the fluid pressure cylinder 34 is connected to the movable member 24, a large force is applied even when the movable member 24 moves due to changes in the outer diameter of the filament body W, etc. Therefore, unnecessary changes in the holding force (tension) of the endless band 26 can be prevented. Furthermore, even if the target filament bodies have different outer diameters, etc., the required pressing force can be easily obtained by simply adjusting the fluid pressure of the fluid pressure cylinder 34. Note that, as in this embodiment, the movable member 24 and the fluid pressure cylinder 34 are connected to the movable pulley 3.
If they are connected via 0A and 30B, the effect of preventing fluctuations in the pressing force of the endless band 26 can be further enhanced.

[Effect of idea]

As is clear from the above explanation, according to the device for holding down the elongated attached body to the traveling linear body of this invention, the fluid pressure cylinder is connected to the moving member, so even if the moving member moves. There is no unnecessary change in the restraining force of the endless band that wraps around the filament and the long attached body attached to it, and even when the outer diameter of the target filament varies. Effects such as being able to easily apply a required pressing force to the endless band simply by adjusting the fluid pressure of the fluid pressure cylinder can be obtained.
