JP-A-8-65850 Japanese Patent No. 3999632

  In the case of a cable having a particularly large diameter, the covering material around the copper wire is also thick, and the covering material is in close contact with the cable. For this reason, the covering material cannot be easily separated from the central copper wire simply by cutting the cable with the upper and lower rotary blades. Therefore, in the conventional cable covering material separating apparatus, after cutting the covering material with a rotary blade, the operator must peel the covering material from the copper wire with a tool or manually, which takes time and requires a lot of force. It was a work.

  An object of the present invention is to provide a cable covering material separating device that can easily separate a covering material from an electric wire of a cable.

  A cable coating material separating apparatus according to a first aspect of the present invention includes a pair of rotary blades whose blades are arranged to face each other, a guide bar for guiding the cable between the rotary blades, and the rotary blades facing each other. A guide cover for guiding the cable, located upstream from the position, and a judgment part for spreading the cut portion of the cable covering material, which is located downstream of the rotary blade and cut by the rotary blade, And a guide plate for guiding the cable that has passed through the judgment portion, and the guide cover and the guide plate are inclined toward the upstream side and away from the facing position of the rotary blade. It has an inclined surface.

In the present invention, when the cable guided by the guide bar and the guide cover is supplied between the pair of rotary blades, the rotary blades cut the covering material of the cable. Thereafter, the cut portion of the cable from which the covering material is cut is pushed and widened by the separating portion located on the downstream side of the rotary blade. The cable is conveyed further downstream while being guided by the guide plate.
According to the cable coating material separating apparatus according to the present invention, since the separating portion is provided on the downstream side of the rotary blade, the cut portion of the coating material cut by the rotary blade can be expanded. Therefore, the covering material is easily peeled off from the electric wire at the center of the cable, and the covering material is easily separated from the electric wire. Further, since the guide bar is provided, the cable is reliably guided to the position facing the rotary blade, and the covering material is reliably cut.

Here, the cable is often coiled and stored, and may be curved when pulled out. In such a case, when the curved cable moves in the cable covering material separating apparatus, the movement may be hindered by interference with surrounding members. However, in the present invention, a guide cover is provided on the upstream side of the rotary blade, and the guide cover is inclined toward the upstream side in a direction away from the facing position of the rotary blade. For this reason, even when cutting the cable covering of a bent cable, the guide cover does not hinder the movement of the cable guided toward the position facing the rotary blade, and therefore the cable rotates without applying excessive force. Guided to the opposite position of the blade.
In particular, in the case of a cable that is curved in the direction approaching the judgment part from the position facing the rotary blade, the load applied to the judgment member when the cable passes through the judgment part after the curved cable has passed the position opposed to the rotary blade. It is possible that the cable will move and stop moving. In the present invention, a guide plate is provided on the downstream side of the rotary blade, and the guide plate has an inclined surface that is inclined toward the upstream side away from the opposed position of the rotary blade. After the material is cut, the cable that has passed through the separating portion is guided by the guide plate, so that the cable reliably moves downstream without being caught by the separating member.

In the embodiment of the present invention, it is preferable that at least a part of the upstream end portion of the guide plate is located on the upstream side of the judgment portion.
In this embodiment, since at least a part of the upstream end portion of the guide plate is located upstream of the separating portion, the cable moved downstream from the position facing the rotary blade is separated by the guide plate. It is guided on the upstream side of the cable, and the conveyance of the cable to the downstream side is stabilized.

Furthermore, in another embodiment of the present invention, it is preferable that at least one inclined surface of the guide cover and the guide plate is a flat surface.
In this other embodiment, since the inclined surface of at least one of the guide cover and the guide plate is a flat surface, the cable can be guided downstream with a simple shape.

One end of the upper rotary shaft 8 and the lower rotary shaft 10 protrudes from the support column 2, and the upper rotary blade 12 and the lower rotary blade 14 are fixed to these ends, respectively. The other ends of the upper rotary shaft 8 and the lower rotary shaft 10 are connected to a drive mechanism (not shown) and are rotatable in opposite directions. Specifically, the upper rotating shaft 8 rotates clockwise in FIG. 3, and the lower rotating shaft 10 rotates counterclockwise in FIG.

A gap G (FIG. 4) in which the cable C is inserted between the opposed positions of the upper rotary blade 12 and the lower rotary blade 14, that is, between the lower edge portion of the upper rotary blade 12 and the upper edge portion of the lower rotary blade 14. Is formed.

  The separating member 16 is a plate-like member that is arranged on the downstream side of the upper rotary blade 12 and the lower rotary blade 14 and is arranged in the vertical direction and on the same plane as the upper rotary blade 12 and the lower rotary blade 14. The separating member 16 has a concave portion 26 that opens upward at substantially the center of the upper edge 24, and the upper edge 24 </ b> A on the downstream side of the concave portion 26 is inclined downward toward the upstream side. The upper edge 24 </ b> B on the upstream side of the recess 26 of the separating member 16 is formed such that the upper edge is flat in the horizontal direction and protrudes above the height of the downstream upper edge 24 </ b> A adjacent to the recess 24. An arcuate recess 30 is formed on the upstream side edge 28 of the separating member 16 so as not to interfere with the lower rotary blade 14. With such a shape, a separating portion 32 that protrudes upward and upstream is formed on the upstream side of the recess 24 of the separating member 16. The upstream end portion of the separating portion 32 is tapered toward the upstream side. Further, the upper end 32 </ b> A of the separating portion 32 is located at a height position substantially the same as the height position of the uppermost end of the lower rotary blade 14.

  The guide mechanism 18 is a guide bar 34 for guiding the cable C to the gap G, a guide cover 36 for guiding the cable C together with the guide bar 34, and a downstream side of the gap G. And a guide plate 38 for guiding the cable C with the covering material cut.

  A pair of guide bars 34 are provided on both the left and right sides of the gap G between the upper rotary blade 12 and the lower rotary blade 14. Each guide bar 34 is a bar-like member that is arranged in the direction substantially parallel to the plane of the upper rotary blade 12 and the lower rotary blade 14 from the upstream side of the upper rotary blade 12 and the lower rotary blade 14 to the position of the gap G. The upstream portion of the guide bar 34 is an inclined portion 34A that is inclined so that the surfaces facing the other guide bar 34 are close to each other toward the downstream side. Parallel portions 34B arranged in parallel to each other are formed on the downstream side of the upstream portion 34A. Each of these guide bars 34 is fixed to a support member 40, and these support members 40 are provided so as to be slidable so as to approach and separate from each other by a moving mechanism 42. Therefore, by operating the handle 44 of the moving mechanism 42, the guide bar 34 moves in the direction of approaching and separating.

  The guide cover 36 is a pair of plate-like members fixed to the support member 40 at a position below the inclined portion 34 </ b> A of the guide bar 34 so as to cover the space between the pair of guide bars 34. Each guide cover 36 has an inclined surface 36 </ b> A, which is a flat flat surface inclined in the direction away from the gap G toward the upstream side, that is, toward the upstream side. A flat surface 36B extending in the horizontal direction is formed on the downstream side of 36A. The flat surface 36 </ b> B is disposed at a lower height position than the height position of the uppermost end of the lower rotary blade 14. Since the guide cover 36 is fixed to the support member 40, the guide cover 36 can be moved so as to be close to and away from each other like the guide bar 34. When the end portions approach each other, one end portion becomes the other. It arrange | positions in the up-down direction so that it may overlap with the edge part.

  The guide plate 38 is a plate-like member fixed to the upper edge 24 </ b> A on the downstream side of the concave portion 26 of the separating member 16, and is disposed substantially perpendicular to the installation plane of the separating member 16. According to the inclination of the upper edge 24A, the guide plate 38 is an inclined surface that is a flat surface inclined downward in the upstream direction, that is, in the direction away from the gap G toward the upstream side. In the guide plate 38, a slit 46 that opens toward the upstream side is formed at a portion upstream of the concave portion 26 of the separation member 16, and the separation portion 32 is accommodated in the slit 46. Therefore, the guide plate 38 extends on both the left and right sides of the separating portion 32, that is, the portion of the guide plate 38 upstream of the recessed portion 26 of the separating portion 32 is divided into left and right. The upstream end of the left portion 38A (the left portion as viewed from the upstream side or the portion far from the support column 2) of the upstream portion of the guide plate 38 is located downstream and below the upstream end of the separating portion 32. positioned. The right portion 38B of the upstream portion of the guide plate 38 is formed longer than the left portion 38A, and its upstream end is located upstream and below the upstream end of the separating portion 32.

FIG. 4 is a cross-sectional view showing the operation of the cable covering material separating apparatus 1 according to one embodiment of the present invention.
The cable C inserted into the cable covering material separating apparatus 1 has a copper wire X inside, and a covering material Y is covered around the copper wire X. The handle 22 is operated according to the diameter of the cable C to drive the moving mechanism 20, and the gap G between the upper rotary blade 12 and the lower rotation 14 is substantially the same as the diameter of the copper wire X. Adjust the size of the gap G. Next, by operating the handle 44 to drive the moving mechanism 42, the distance is adjusted so that the distance between the guide bars 34 is substantially the same as the diameter of the cable C. At this time, since the guide cover 36 is fixed to the support member 40 together with the guide bar 34, the guide cover 36 moves in a direction approaching or separating from each other as the guide bar 34 moves.

  When the cable C is inserted between the guide bar 34 above the guide cover 36 from the upstream side, the cable C is inserted between the upper rotary blade 12 and the lower rotary blade 14 while being guided by the guide bar 34. Since the upper rotary blade 12 and the lower rotary blade 14 rotate in directions opposite to each other, the cable C is moved to the downstream side while cutting only the covering material Y of the cable C. The cable C is conveyed to the separating member 16 in a state where the upper and lower portions of the covering material Y are cut.

  When the cable C is conveyed to the separating member 16 in a state where the upper and lower portions of the covering material Y are cut, the upstream end of the separating portion 32 becomes a cut portion of the covering material Y cut by the lower rotary blade 14. Inserted. The separating portion 32 is tapered toward the upstream side, that is, the width increases toward the downstream side, so that the cut portion is pushed and expanded by the separating portion 32 as the cable C is conveyed downstream. Thereby, the coating material Y is conveyed downstream in a state where the coating material Y is peeled from the copper wire X.

Here, the cable C may be coiled and stored, and in that case, when the cable C is unwound, the cable C may be curved. For example, when the cable C is curved in the left-right direction or the upward direction, the guide bar 34, the upper rotary blade 12, and the lower rotary blade 14 correct the cable curve to some extent while conveying the cable C and the covering material Y. Make a cut.
On the other hand, when the cable C is inserted into the cable covering material separating apparatus 1 while being curved downward, it is avoided that the cable C is pushed from below by the inclined surface 36A of the guide cover 36. On the other hand, the cable C exiting the upper rotary blade 12 and the lower rotary blade 14 is prevented from being bent downward by the guide plate 38.

According to the present embodiment configured as described above, the following excellent effects can be obtained.
Since the guide bars 34 are provided on the left and right sides of the upper rotary blade 12 and the lower rotary blade 14, the cable C can be guided so that the central axis of the cable C is aligned with the upper rotary blade 12 and the lower rotary blade 14. Therefore, the upper rotary blade 12 and the lower rotary blade 14 can cut the covering material Y at an appropriate depth along the central axis of the cable C.

  Since the separating member 16 is provided on the downstream side of the upper rotating blade 12 and the lower rotating blade 14, the cut portion of the covering material Y of the cable C is pushed and spread by the separating portion 32. Therefore, the covering material Y of the cable C exiting the cable covering material separating apparatus 1 can be easily separated from the copper wire X, and the covering material can be easily removed.

  A guide cover 36 is provided below the guide bar 34. Since the guide cover 36 has an inclined surface 36A inclined downward toward the upstream side, the cable covering is performed in a state where the cable C is curved downward. When inserted into the material separating apparatus 1, the guide cover 36 can be prevented from pushing the cable C from below as compared with the case of moving on a flat table, and the cable C is bent downward to some extent. Can be left. Therefore, it is possible to prevent a large load from being applied to the cable C during the movement of the cable C, and the cable C can be transported smoothly.

  As described above, when the cable C is inserted into the cable covering material separating apparatus 1 in a state of being curved downward, the cable C that has passed through the upper rotary blade 12 and the lower rotary blade 14 moves downward. For this reason, as the cable C moves, the covering material Y pierces the separating portion 32, and the load applied to the separating portion 32 increases. In some cases, the cable C cannot move any more. In the present embodiment, the guide plate 38 is provided on the downstream side of the upper rotary blade 12 and the lower rotary blade 14, and the guide plate 38 is formed as an inclined surface that is inclined downward toward the upstream side, so that the cable C is curved downward. When it moves, the guide plate 38 guides the cable C upward. Therefore, it is possible to reduce the load applied to the separation portion 32, and it is possible to prevent a problem that the cable C is caught on the separation portion 32 and cannot be moved.

  Since the right side portion 38B of the upstream portion of the guide plate 38 is located upstream of the upstream end of the separating portion 32, the cable C that has passed through the upper rotating blade 12 and the lower rotating blade 14 is reliably separated. You can guide up to 32.

  Since the guide cover 36 has a flat inclined surface 36A, and the guide plate 38 is a plate-like member that forms the inclined surface, for example, the guide cover 36 and the guide plate 38 are formed in comparison with a structure having a curved surface. It can be manufactured easily.

The present invention is not limited to the above embodiments, and various modifications are possible within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
For example, in the above-described embodiment, the right side portion 38B of the upstream portion is located upstream of the judgment portion in the above-described embodiment, but the left side portion 38A is located upstream of the judgment portion. In short, it is only necessary that at least a part of the guide plate is located on the upstream side of the separating portion. Further, the guide plate does not necessarily need to be positioned upstream of the judgment portion at the upstream end, and may be located downstream of the judgment portion.

In the above-described embodiment, the guide cover 36 and the guide plate 38 have flat inclined surfaces. However, the guide cover 36 and the guide plate 38 are not limited thereto, and may be configured to have, for example, an arcuate curved surface. In short, the guide cover and the guide plate may be inclined in the direction away from the facing position of the rotary blade toward the upstream as a whole.
The judgment part was provided so as to protrude upward from below, and was configured to spread the cut portion of the covering material cut by the lower rotary blade. However, the invention is not limited to this. For example, the judgment part is downward from above. It may be configured to protrude so as to push out a cut portion of the covering material cut by the upper rotary blade. In this case, it is preferable that the guide cover and the guide plate are also provided on the upper rotary blade side.
