Description

  The present invention relates to a linear body feeding device for feeding a linear body wound around a reel with a predetermined tension in a production line for electric wires and cables.

  In a production line for electric wires and cables, etc., in order to apply a predetermined tension to the wire rod used as a material and feed it out, generally the wire rod is stretched between a brake wheel and a plurality of free wheels, and the brake foil is attached. The tension | tensile_strength of a linear body is provided by braking (for example, refer patent document 1). Further, in the linear body feeding device, a cushion portion is provided between a supply unit that feeds the linear body wound around the reel and a tension applying unit that applies tension to the linear body. In this way, it is possible to absorb and mitigate sudden changes in the feeding speed and tension fluctuation of the striate body from the supply section. In addition, as a factor of the feeding speed fluctuation and tension fluctuation of the linear body, there are a winding diameter variation when the winding is not completely aligned, a drop in a lower layer, a bite, and the like in addition to the time of starting and stopping.

  5-8 is a figure explaining an example of the conventional linear body feeding apparatus mentioned above. As shown in FIG. 5, the linear member 4 is fed from the supply unit 1 while being wound around the reel 12, and passes through the guide wheel unit 6 and the slide wheel unit 5 of the cushion unit 2, and then the tension applying unit 3. A predetermined tension is applied by the brake wheel unit 7 and the free wheel unit 8 and is sent to the next process.

  As shown in FIG. 6, the supply unit 1 has a reel 12 around which a linear member 4 is wound around a reel shaft 11 fixed thereto, and the reel shaft 11 can be rotated to a support frame 15 by a bearing 14 such as a bearing. It is supported. A reel brake 13 that brakes the rotation of the reel 12 is connected to the reel shaft 11, and tension is applied to the linear member 4 between the reel shaft 11 and the cushion portion 2. This tension does not loosen the striate body 4, does not affect the quality (elongation, deformation, etc.) of the striatum, and does not cause biting or entanglement between the striates wound around the reel 12. The tension is such that smooth feeding is possible.

  As shown in FIG. 7A, the cushion portion 2 includes a slide wheel 20 that is rotatably provided on a slide wheel shaft 21 by a bearing 22 such as a bearing, and an urging means 23 such as a spring. A slide wheel unit 5 having a slide shaft 24 and a slide means made up of a slide member 25 that are urged to move the slide wheel shaft 21 in the vertical S direction is provided. This slide wheel unit 5 absorbs and relaxes the speed fluctuation and tension fluctuation of the linear body 4 drawn from the reel so that the upward linear body tension and the downward weight / biasing force are balanced. Yes. Further, a guide wheel unit 6 for guiding the filament 4 from the supply unit 1 to the slide wheel 20 is provided as necessary.

  The guide wheel unit 6 includes, for example, a guide wheel 26a that guides the slide body 20 to the slide wheel 20 and a guide wheel 26a that guides the linear body 4 from the slide wheel 20 to the brake wheel side. It is formed by two guide foils of the foil 26b. The two guide wheels 26a and 26b are rotatably supported on a guide wheel shaft 27 supported and fixed to a support frame 29 using a bearing 28 such as a bearing. In addition, in order to smoothly lay the wire 4 on one slide wheel 20 and two guide foils 26a and 26b, as shown in FIG. The slide wheel shaft 21 on the slide wheel unit 5 side is slightly inclined with respect to the guide wheel shaft 27 of the guide wheel unit 6.

  The tension applying unit 3 is configured as disclosed in Patent Document 1, for example, as shown in FIG. 8 (A), from a brake wheel unit 7 on the driving side and a free wheel unit 8 on the driven side thereof. Become. The brake wheel unit 7 has a configuration in which a linear body 4 is wound around a cylindrical brake wheel 30 by a plurality of turns, a brake wheel shaft 31 is connected, and is supported rotatably on a support frame 34 by a bearing 33 such as a bearing. By applying rotational resistance by 32, tension is applied to the filament 4. Although this tension is determined by the manufacturing conditions in the next process, it is usually a value that exceeds the tension applied by the supply unit 1, so this unit is required.

The freewheel unit 8 is configured such that a plurality of freewheels 35 are rotatably provided on a freewheel shaft 36 using a bearing 37 such as a bearing, and the freewheel shaft 36 is supported and fixed to a support frame 38. In addition, in order to smoothly pass the filament 4 between the brake wheel 30 and the free wheel 35, as shown in FIG. 8 (B) by the ee arrow of FIG. 8 (A), the free wheel unit 8 The free wheel shaft 36 is slightly inclined with respect to the brake wheel shaft 31 of the brake wheel unit 7.

  The wire feeding device is configured as an independent device because the functions of the supply unit 1, the cushion unit 2, and the tension applying unit 3 are different, and in a series state along the running direction of the wire 4. Be placed. As for the outer diameter of each foil used in these apparatuses, the bending applied to the wire body 4 affects the quality of the product. For example, if the product is an iron wire, plastic deformation due to bending is a problem, if it is a copper twisted wire for communication, the twisted shape is broken, and if it is an optical cable for communication, the arrangement is disturbed and the transmission characteristics are deteriorated. Is a problem.

The outer diameter of each foil varies depending on the product type of the striated body. For example, in the case of an electric wire, the outer diameter of the used foil is 20 to 40 times the outer diameter of the striated body. As a result, if the three devices of the supply unit 1, the cushion unit 2, and the tension applying unit 3 are arranged in a series state along the traveling direction, the equipment becomes large and increases the manufacturing cost.
