  As shown in FIG. 5, the electric wire covering removal device 1 removes the electric wire covering waste W2 attached to the cutters 21 and 21 from the cutters 21 and 21 by the air blown by the air outlet 43a, and the inlet opening 44a. Is introduced into the electric wire covering waste discharge guiding path 44 and is discharged to the outside of the apparatus from the discharge port 44 b while being guided by the electric wire covering debris discharging guiding path 44 while being guided by the air flow generated by the air blowing unit 43.

Next, operation | movement of the electric wire coating removal apparatus 1 is demonstrated, demonstrating the removal procedure of the electric wire coating W1 using the electric wire coating removal apparatus 1 using FIGS.
FIG. 6A is a view of an operator setting an electric wire in the electric wire sheath removing apparatus 1 as viewed from the outside of the apparatus. FIG. 6B is a state in which an electric wire W is set in the electric wire sheath removing apparatus 1. It is the figure which looked at a mode that removal processing of electric wire covering W1 is carried out from the outside of an apparatus. FIG. 7 is a view of the state in which the operator pulls out the electric wire W from the apparatus after the removal process of the electric wire covering W2 by the electric wire covering removing apparatus 1 is completed, as viewed from the outside of the apparatus. FIG. 8A is a view showing that the operator sets the electric wire W to the electric wire covering removal apparatus 1 so that the inside of the apparatus can be seen, and FIG. 8B shows the electric wire covering removal apparatus 1 being the electric wire covering W1. It is the figure which showed a mode that the removal process of is implemented so that the inside of an apparatus could be seen. FIG. 9 is a view showing that the inside of the apparatus is visible so that (a) is blowing air from the air blowing portion toward the cutter 21, and (b) is an electric wire covering W <b> 1 by the electric wire covering removing device 1. It is the figure which showed that the inside of an apparatus can see a mode that an operator pulls out the electric wire W from an apparatus after completion | finish of a removal process.

  First, an operator sets an electric wire in the electric wire sheath removal apparatus 1 (refer FIG. 6 (a) and FIG. 8 (a)). Here, an operator arrange | positions the electric wire W in the set position of the electric wire W of the electric wire coating removal apparatus 1 by abutting the front end surface of the electric wire W on the abutting part 42a. Prior to this work, the operator adjusts the position of the abutting portion 42a to a desired position by operating the position adjustment dial 42c.

Then, an operator starts the electric wire coating removal process by the electric wire coating removal apparatus 1 (refer FIG.6 (b) and FIG.8 (b)). Here, for example, the operator starts an electric wire covering removal process by the electric wire covering removing apparatus 1 by operating an operation unit such as a foot switch (not shown).
Thereby, after a pair of clamping part 41a, 41a hold | maintains the electric wire W in the set position which abutted against the abutting part 42a, a pair of cutters 21 and 21 approach each other with respect to the electric wire W hold | maintained in the set position. A cut is made in the sheath W1, and the wire sheath W1 with the cut is moved so as to be disconnected from the wire W.

  Thereafter, air is blown from the air outlet 43a toward the cutters 21 and 21 with respect to the pair of cutters 21 and 21 moved so as to separate the wire covering W1 from the wire W (see 9 (a)). Here, when the wire covering debris W2 removed from the electric wire is attached to the cutter, the wire covering debris W2 removed from the cutters 21 and 21 by the air enters the wire covering debris discharge guiding path 44 from the inlet opening 44a, and the electric wire It is removed to the outside of the apparatus by the covering waste discharge guiding path 44.

Since it can be discharged to the outside, it is possible to discharge the wire-covered waste W2 to the outside of the apparatus without providing a suction device. It is possible to prevent the removed wire coating W1 from remaining attached to the cutters 21 and 21.

  Moreover, since the electric wire covering removal apparatus 1 which concerns on the Example of this invention can direct the direction of the air which blows on the cutters 21 and 21 from the air blower outlet 43a to the apparatus outward side from an apparatus inner side, it is cutter by air. It is possible to make it difficult for the wire-covered scrap W2 removed from the devices 21 and 21 to remain inside the apparatus, and as a result, it is possible to suppress the occurrence of defects due to the insulating-covered scrap W2.

  Moreover, the electric wire covering removal apparatus 1 which concerns on the Example of this invention can form the path | route which connects an apparatus inside and an apparatus exterior by the electric wire covering waste discharge | emission guide path 44 penetrating the one wall 11a. Therefore, as a result, the wire covering waste W2 can be guided from the inside of the apparatus to the outside of the apparatus without forming a complicated path of the wire covering waste discharge guiding path 44 inside the apparatus.

  Moreover, since the entrance opening 44a is formed in the cover part 11, the electric wire covering removal apparatus 1 which concerns on the Example of this invention can perform maintenance, such as cleaning of the electric wire covering waste discharge induction path 44, by opening the cover part 11. Can be done.

Moreover, the electric wire covering removal apparatus 1 which concerns on the Example of this invention blows in in the electric wire covering waste discharge induction path 44 from the air blower outlet 43a by forming the air vent hole 47 in the electric wire covering waste discharge induction path 44. The air flow can be adjusted to prevent the air blown from the air outlet 43a into the wire covering debris discharge guiding path 44 from flowing back into the inlet opening 44a. It is possible to prevent the wire covering debris W2 introduced into 44 from returning to the inside of the apparatus from the inlet opening 44a.

  By forming the wire covering waste discharge guiding path 50 of the wire covering removing apparatus 2 of this modified example so that the path bent in the horizontal direction from the path connected in the vertical direction from the inlet opening 50a is shorter than the embodiment, The wire covering waste W2 blown and introduced into the wire covering debris discharge guiding path 50 from the inlet opening 50a falls vertically to the discharge port 50b over a short distance.

  The electric wire covering removal apparatus 2 of this modification introduces the electric wire covering waste W2 removed from the cutters 21 and 21 by the air blown from the air outlet 43a into the electric wire covering debris discharge guiding path 50 from the inlet opening 50a. The electric wire covering waste W2 introduced into the covering debris discharge guiding path 50 is moved in the electric wire covering debris discharge guiding path 50 on the air flow blown from the air outlet 43a, and discharged from the discharge port 50b to the outside of the apparatus. Therefore, similarly to the wire sheath removing apparatus 1 of the embodiment, the wire covering waste W2 can be discharged to the outside of the device without providing a suction device, resulting in a simple device configuration. It is possible to prevent the wire covering W1 removed from the wire W by the cutters 21 and 21 from being attached to the cutters 21 and 21.

  In addition, although the electric wire covering removal apparatuses 1 and 2 which concern on the Example of this invention illustrated what formed the air vent hole 47 in the electric wire covering waste discharge induction path | routes 44 and 50, it is not restricted to this, For example, a discharge port A structure in which the air vent hole 47 is not formed may be formed by adjusting the dimensions of 44b and 50b, the shape of the path, and the like so that the air does not easily flow backward.

  The invention made by the present inventor has been specifically described based on the above-described embodiments of the invention. However, the present invention is not limited to the above-described embodiments of the invention and does not depart from the gist thereof. Various changes can be made.
