In Japanese Patent Application No. 1-1-199779, a grounding wire P shown in FIG.
Each of the grounding wires P shown in the figure was proposed. In each of these electric wires P, a protective coating 2 having a crescent-shaped or flat trapezoid cross section is provided around an insulated wire 1, and a cavity 3 is formed inside the protective coating 2 as appropriate (Fig. 6, Fig. 7). The bottom side 2a of the cross section of the protective coating 2 is attached to the utility pole H.

ら３ｍ前後に切断される。On the other hand, as mentioned above, the electric wire P has its protective coating 2 made of PVC,
Since it is made of hard resin such as HDPE, it is once rolled onto a drum (
It had a curly curl, and it was difficult to remove the curl and was very bothersome. Also, considering the purpose of use of this electric wire P, it is necessary to prevent passersby from touching the grounding wire, so it is cut to a length of about 3 m.
これまでは、上記くせとつと一定長に切断する作業を別
途行っていたので、余分の人手が必要であり、くせ取り
が困難で切断長も正確でなかった。Until now, the work of cutting the above-mentioned curls to a certain length was performed separately, which required extra manpower, making it difficult to remove the curls, and the cutting length was not accurate.

って電線案内函軌条と切断函は元の位置に復帰する。In the fixed length cutting device according to the present invention configured as described above, when an electric wire is fed from the feeding means, the electric wire passes through the electric wire through hole of the blade receiver and slides along the inner surface of the back of the electric wire guide box track, When the tip hits the cutting length setting piece and is fed further, the wire guide box rail and the cutting box connected thereto are pushed downstream against the biasing force of the spring. When the push reaches the required distance, the head of the blade support rod is struck with a hammer, the wire is cut by the blade attached to the blade support rod, and then the wire guide box rail and cutting box are separated by the bias of the spring. Return to original position.
その切断時は、電線の刃受は寄り側は刃により下に押下
げられ、函軌条内面のリプにより逆もどりが阻止されて
空洞が形成され、次に送り込まれる電線の先端を受入れ
る状態となる（第２図（ａ）参照）。When cutting, the edge of the wire blade receiver is pushed down by the blade, and the lip on the inner surface of the box track prevents it from moving back, forming a cavity that will receive the tip of the wire that will be fed next ( (See Figure 2(a)).

れて落下する。Thereafter, the same process is repeated to sequentially cut the wires and store them in the box rail. Tw that is cut off and stays in the box rail
A is prevented from falling by itself by the spring at the opening of the box rail, and descends one after another as the tip of the wire being fed advances, and the outermost wire is detached from the spring by its lower part and falls.

滞留電線との摩擦抵抗が大となって、電線先端が切断条
長設定片に到達する前に函軌条および切断函が動いて所
望より短尺のものが切断されるので、実験的に適度な強
さを選択する。If the spring is too strong, the frictional resistance between the incoming wire and the staying wire will become large, causing the box rail and cutting box to move before the wire tip reaches the cutting length setting piece, resulting in a shorter length than desired. Since things will be cut, choose an appropriate strength experimentally.
また、函軌条を付勢するスプリングが強すぎるときは、
送り込まれた電線が切断済の滞留電線を押し下げて屈曲
して、所望より長尺のものが切断されるので、その強さ
は実験的に選択する必要がある。Also, if the spring that biases the box rail is too strong,
The wire sent in presses down on the cut stagnant wire and bends, resulting in the wire being cut longer than desired, so its strength must be selected experimentally.

。On the downstream side of the cutting box 13, wire guide box rails 22 (hereinafter referred to as box rails) with a U-shaped cross section are installed in series, and the wires P are guided into the box rails 22 at appropriate intervals in the length direction. A spring 27 for retention is installed so as to sandwich the opening of the box rail 22. As shown in FIG. 2(a), on one end side of the inner surface of this box rail 22 (the side of the blade receiver 15 on the right side of FIG. A lip 26 is provided, and this lip 26 allows
The electric wire P is prevented from returning upward when it is lowered by a blade 17, which will be described later. Further, a cutting length setting piece 25 is provided on the other end side of the box rail 22 so as to be movable and fixed in the length direction. When it is fed in and its tip hits the setting piece 21,
As the electric wire P advances, the box rail 22 and the cutting box 13 move. Note that 23 in the figure is a support roller for the box rail 22.

線Ｐが切断される。A cross stroke mechanism 21 is provided at the top of the square box column 12, and the hammer 20 is constantly reciprocated up and down by this mechanism 21. In the cross-stroke mechanism 21, an eccentric shaft 21c fixed to an axial center shaft 218 of a constantly rotating flywheel W is fitted into a hole in a slider 21b in the block 20a of the hammer 20, and the rotation of the eccentric shaft 21c As a result, the slider 21b moves laterally as shown by the chain line in FIG. 1, and also moves vertically to push down the block 20a, that is, the hammer 20. Therefore, when the upper surface of the anvil 16 faces below the hammer 20 (
1 (t*m shape M) in FIG. 1, the upper surface thereof is struck by the hammer 20, the anvil 16, that is, the blade support rod 14 is lowered, and the electric wire P is cut.

うにしている。First, at the time of starting work, the electric wire P cut to a specified length in advance is filled and retained in the box rail 22 as shown in 2nd UXJ (al (b)), and the tip of the electric wire P to be fed next is connected to the cutting length setting piece. This prevents fm from bending when it hits 25.

When the electric wire P enters the box rail 22 and hits the cutting length setting piece 25, the wire P moves against the spring 24 through the setting piece 25 to move the box rail 22 and the cutting box 13 to the first position.
Move the figure to the left.

is done without bending. When the amount of movement becomes a certain amount, that is, the length of the feed from the blade 17 becomes 3 m, the anvil 16 is positioned below the hammer 20 and is struck as shown by the chain line in the figure, the blade support rod 14 descends, and the blade 17 and the blade receiver 15 cut the electric wire P into a regular length.

。During this cutting, the blade 17 pushes the electric wire P downward, so that the cutting box 13 side of the electric wire P in the box rail 22 is lowered, and this state is maintained by the ribs 26, as shown in FIG. 2(a). A space S is created at the feeding level of the electric wire P. Therefore, after cutting, the spring 24 holds the box rail 22 and the cut box 13.
is restored, but at the same time the next electric wire P
Two people enter the space 54 (Fig. 2 (al chain line)) and advance while pushing down the electric wire P in front. When this action is repeated, the electric wire P facing the lower opening of the box track 22 is pushed down. The claws 2?a of the spring 27 are pushed open from the opening, and the springs are discharged one after another into the machine base 11 (as shown by the chain line in Figure 2).
.
前記実施例において、クロスストローク機構２１に代え
