Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the above-mentioned long length when a long attachment body such as a shield wire is attached to the outer periphery of a linear body such as a running power cable core. The present invention relates to a device for suppressing a long attachment body to a traveling line body, which is used to hold the length attachment body to the linear body.

[Prior Art] For example, as shown in FIGS. 2 and 3, on the outer circumference of a traveling wire core W such as a cable core, a large number of reels 2 ... When the long attached body 3 such as a shielded wire is attached, the long attached body 3 ...
At the location of the attachment of the long attachments 3 ... to the outer periphery of the linear body W, a device for suppressing the long attachments to the running linear body (hereinafter referred to as a pressing device). 4) is provided.

As shown in FIG. 3, this restraining device 4 has a main body 5 made of a plate-like member through which a linear member W such as a cable core is inserted in a central opening portion 6, and guides are provided at four corners of the main body 5. The reel (guide member) 7 and the moving (moving member) reel 8 are
Each is rotatably arranged. An endless belt 9 is stretched around the guide reels 7 ... And the moving reel 8. The endless belt 9 is made of a material having a predetermined tensile strength such as steel or plastic, and is wound around the outer circumference of the filament W to which the long attachments 3 are attached a plurality of times. In addition, it is stretched over the guide reels 7 ... And the moving reels 8. On the other hand, the movable reel 8 is provided on the main body 5 so as to be movable in a pulling direction and a loosening direction of the endless belt 9, and a spring (biasing member) 10 is used to move the endless belt. It is urged in the direction of pulling 9. As a result, the endless belt 9 is stretched between the guide reels 7 ... And the moving reel 8 in a state where a predetermined tensile force is applied.

The conventional pressing device 4 has a rotary plate 12 rotatably provided on the outer periphery of the filament W via a motor 11 at the pressing position of the elongated attachments 3 shown in FIG. Is integrally fixed to. In the figure, reference numeral 13 is the reel 2
Distribution board 14 that guides the long attachment 3 ...
And a drive motor 15 for alternately rotating the distribution board 14 in opposite directions, for example. A linear line running on the elongated attachments 3 ... While imparting a waveform (SZ twist) thereto. 1 shows a corrugating device for attaching to the outer circumference of a body W.

In the conventional restraining device 4 having the above structure, the main body is attached to the outer periphery of the linear body W traveling in the right direction in the figure while the long attached bodies 3 are attached in FIG. As the motor 5 rotates at a predetermined rotational speed by the motor 11, the upstream side of the endless belt 9 sequentially winds around the linear body W, whereby the long attachments 3 ... While being pressed down, the downstream side part of the endless belt 9 which holds down the long attachments 3 ... Is separated from the filament W and the winding is released in synchronization with this. That is, endless belt 9
Is 1 on the upstream side of the linear body W and the long attached body 3.
If it is wound, one winding is unwound on the downstream side, and even if the filament W is running, it is spirally wound on the filament W and the long attachment 3 at the same position. It is what When the outer diameter of the filamentous body W and the winding state of the endless belt 9 change during this period, and the appropriate length (tensile force) of the endless belt 9 changes, the moving reel 8 receives the urging force of the spring 10. It follows this by being displaced against. As described above, the long attachments 3 attached to the outer periphery of the filament W are sent to the next step while being held on the outer periphery of the traveling filament W, and further to the outer periphery thereof. The tape 16 etc. will be wound and fixed.

[Problems to be Solved by the Invention] However, in the above-described conventional pressing device 4,
Since the spring 10 is directly connected to the moving reel 8,
If there is a change in the outer diameter of the linear body W, the spring 10 expands and contracts greatly in accordance with the above-mentioned amount of change, so that the holding force of the endless belt 9 changes greatly and the attachment of the long attachments 3 ... The installation was unstable.

[Object of the Invention] The present invention has been made in view of the above circumstances, and provides a novel restraining device capable of always restraining a long attachment body with a uniform restraining force against a linear body. The purpose is to do.

[Means for Solving the Problems] In the restraint device of the present invention, a plurality of guides are provided on a main body rotatably provided on the outer periphery of a portion of a traveling linear body where a long attachment body is attached. A member is arranged, and an endless band wound around the outer periphery of the linear member having the long attachment member attached thereto is stretched between these guide members, and the endless band is guided and stretched. The movable member movably provided in the moving direction and the urging member for urging the endless belt are connected to each other via a moving pulley mechanism.

[Operation] In the pressing device having the above configuration, since the moving member and the urging member are connected via the moving pulley mechanism, the moving member is displaced due to a change in the outer diameter of the filament. However, the amount of expansion and contraction of the urging member is small, and therefore, the fluctuation of the endless belt holding (tightening) tension for attaching the long attachment body to the linear body is small.

[Embodiment] FIG. 1 shows an example of the restraining device of the present invention.
At a predetermined position on the main body 21 of the holding device 20, there are arranged guide members 22 ... Composed of five sets of guide reels, and a moving member 24 composed of a movable reel. An endless band 26 made of a material such as steel or plastic that is wound several times around the outer periphery of the filament W such as a cable core is stretched across the guide members 22 ... And the moving member 24. . Here, the moving member 24 is provided movably in a direction in which the endless belt 26 is stretched and loosened on the guide 28 attached to the main body 21. The moving member 24 is composed of two sets of small guide reels.
Wires 32 and 33 are connected to a biasing member 34 in which a spring is incorporated through a moving pulley mechanism 31 composed of 29 and 29 and moving pulleys 30A and 30B.

That is, one end of the wire 32 is attached to the moving member 24, and the other end of the wire 32 is sequentially guided to the small guide reel 29, the movable pulley 30A, the small guide reel 29 and the movable pulley 30B and fixed to the fixture 35. Has been done. The movable pulleys 30A and 30B are both rotatably held by the movable pulley retainer 36, and the movable pulley retainer 36 further urges the movable pulley retainer 36 via the wire 33 in the direction to pull the movable pulley retainer 36. It is connected to the member 34. As a result, the endless belt 26 is stretched in a state in which a predetermined tension is applied via the moving pulley mechanism 31 including the moving pulleys 30A and 30B and the moving member 24. The restraining device 20 having the above structure is rotatably provided in the direction of the arrow in FIG. 1 on the outer periphery of the traveling linear body W by a rotation driving device (not shown).

However, in such a restraining device 20, since the moving member 24 and the urging member 34 are connected to each other via the moving pulley mechanism 31, the moving member is changed as the outer diameter of the filament W changes. Even if 24 is displaced, the amount of expansion / contraction of the biasing member 34 is extremely small (W /
(The number of moving pulleys), so that the endless belt 26 is pressed down (tightened) for attaching the long attachment body 3 to the filament W.
The fluctuation of tension can be made small.

[Advantages of the Invention] As is clear from the above description, according to the device for suppressing a long attachment to a running linear body of the present invention, it is possible to reduce fluctuations in the tightening force of the endless belt, Therefore, the long attached body can be surely pressed against the linear body with a uniform tightening force.
