Description

  The present invention is used in machine tools, electronic devices, industrial robots, transport machines, etc., and electric cables, optical fiber cables, and fluid supplies for supplying power, supplying liquid, supplying air, etc. to these moving machines or moving parts of the machines The present invention relates to a cable protection guide device for protecting and guiding a flexible cable such as a hose or the like (hereinafter referred to as “cables”).

  If cables are connected to a moving body such as a machine tool, civil engineering machine, or conveying device, excessive twisting or pulling force will occur on the cables as they move, and these cables will be damaged and the appearance will be messy. A cable protection guide device that guides and guides cables is used.

  Therefore, as a conventional cable protection and guide device, a conduit carrying a conductor, gas, etc. and a support member made of a continuous material strip having a series of non-interlocking operation-restricted solids are enclosed in a plurality of channels in parallel. An arrangement is known (for example, see Patent Document 1).

Japanese Patent No. 4157096 (claims, paragraphs [0031] to [0034], FIG. 21)

  However, in the conventional cable protection and guide device, the flexible material constituting the support member is a stainless steel material or a leaf spring, so when the bending posture is exhibited, an accurate bending radius cannot be maintained, and the bending radius is There is a problem that it becomes difficult to install in a predetermined space by contacting an obstacle or the like at an adjacent position. Especially when a stainless steel material is used as a flexible material, it is long. There was a problem that fatigue breakage occurred due to use over a period of time, and it was impossible to use.

  And since the flexible material which comprises a support member is stainless steel material and a leaf | plate spring, since a stainless steel material and leaf | plate spring cannot be easily cut and joined, when changing the length of a support member long, another new There is a problem that the support member must be replaced and wasteful use of the support member occurs, and since the torsional rigidity is low when bending, resonance occurs and the operation of the bending posture and the linear posture becomes unstable. There was a problem.

  Furthermore, it is necessary to injection-mold pieces made of resin on a stainless steel material or a leaf spring one by one, which requires a great burden and time during manufacture, and there is a problem that mass production is impossible.

  Therefore, the present invention solves the conventional problems, that is, the object of the present invention is to guide and guide the cable by reliably protecting the cables by avoiding mutual contact of the cables with a bending posture or a linear posture. In addition, an articulated cable protection and guide device is provided in which the articulated support member is composed only of a lightweight synthetic resin block body and can be easily connected according to the use situation.

  The present invention according to claim 1 is a flexible product formed by integrally molding a plurality of central tubular portions that can be inserted for each cable and a pair of left and right side tubular portions arranged in parallel along the central tubular portion.

And although the flexible belt member 110 mentioned above is not shown in figure, it uses two sheets which laminated | stacked the fluororesin layer on both the front and back of the polyurethane resin layer, and each inserts cables between these sheets 4 A central tubular portion 111 of a book and a pair of left and right lateral tubular portions 112 arranged in parallel along the central tubular portion 111 are bulged on the front and back and integrally molded.
As a result, the polyurethane resin layer exhibits the stretchability of the flexible belt member 110 and the self-lubricating action of the fluororesin layer exhibits the slidability of the flexible belt member 110 to protect the cables C without resistance. be able to.

  On the other hand, the multi-joint support member 120 described above is composed of only a large number of synthetic resin block bodies 121 that are concavo-convexly connected to each other and flexibly connected as shown in FIGS.

The detailed form of the synthetic resin block body 121, which is the most characteristic feature of the articulated cable protection guide device 100 of this embodiment, will be described in detail with reference to FIGS.
That is, as shown in FIGS. 2 to 3, a pair of left and right connecting pins 121a is provided on the front side surface portion of the synthetic resin block body 121 described above, and a pair of left and right connecting pins 121a are provided on the rear side surface portion thereof. A connecting pin hole 121b is provided.
As a result, the connecting pin 121a of the synthetic resin block body 121 is pivotally supported in a concave and convex manner in the connecting pin hole 121b provided in the rear side surface portion of the preceding synthetic resin block body 121, and is mutually synthesized. The resin block body 121 is connected to bend freely.

Further, a taper-shaped notch portion 121c for fitting the above-described connecting pin 121a to the connecting pin hole 121b from above and below in the rear side portion of the synthetic resin block 121 is connected to the rear side portion. The hole 121b is continuously recessed.
Accordingly, when the synthetic resin block bodies 121 of the multi-joint support member 120 are connected to each other, as shown in FIG. 4, the connecting pin 121 a of the subsequent synthetic resin block body 121 is preceded by the synthetic resin block body 121. The coupling pin hole 121b is mounted without requiring an excessive fitting input via the notch fitting portion 121c, and the joining according to the use situation is easily achieved.

Further, at different positions on the front side of the synthetic resin block body 121, as shown in FIGS. 2 to 7, the front and rear synthetic resin block bodies 121 are positioned in contact with each other from above and below.

As a result, the cables C protected in the central tubular portion 111 can be guided and guided reliably and smoothly with the multi-joint support member 120 in a linear posture and a bent posture.

  Further, since the multi-joint support member 120 is constituted only by a large number of synthetic resin block bodies 121 that are concavo-convexly connected to each other and flexibly connected to each other, it is difficult to make a conventional connection made of a stainless steel material. Compared to a flexible material, it is possible to easily achieve the connection of the multi-joint support member 120 according to the use situation, and it is possible to reliably protect and guide the cables C with a bent posture or a straight posture, and as in the conventional case. Compared with a support member that had to have various long and short dimensions according to various use conditions, the number of parts is reduced, so that the effect of managing parts can be remarkably reduced.
