Description

Method and apparatus for stripping the sheath of a cable {A methor and mechanism strip cable away}

The present invention is to peel off the part coated on the coated wire, in particular the optical cable, to improve the productivity and ensure the stability of the work.

Currently, the work for stripping the coated wire is the main method of forcibly peeling the coated cover by hand with a knife blade, but the main disadvantage is that the workability is difficult.

Therefore, in recent years, if the electric wire entered from the rear end of the roller is pushed forward by the rotation of the roller, only the coating member of the electric wire passing through the roller by the blade part mounted on the front end of the fixed body on which the roller is mounted is cut. It is performed by mechanical work that separates the wire and the cover by pulling the cover and then pulling the cover to connect it with a clamp or the like.

However, considering that the material of the cover is plastic when the cover is forcibly pulled after cutting the cover with a blade in the coated state, it is cut off according to the degree of pulling due to the tensile force of the plastic. There is a lot of difficulty in continuity.

In addition, the tensile strength of the cladding is changed according to the summer or winter, and when the pulling force is changed during the pulling operation, many problems occur in the continuous operation.

In addition, in order to recycle the plastic raw material in the state of coating the coating should be finely chopped such that in this case there is a lot of problems in the workability is accompanied by another work.

Therefore, in the present invention, there is no breakage of the coating to be separated, and production is possible without breaking the coating even when the pulling force is changed.

In addition, the cutting of the coating can be performed simultaneously to improve productivity.

To do this, the coated wire passes through the guide roller and enters the entry roller. When the wire passes through the pull roller, the blade holder with the blade is formed so that the cut line is formed on the coating. Heat is transmitted only to the iron core formed at the center of the heat while the heat is transferred to the coated wire and the sheath is expanded and the cut is broken and the sheath is opened.

At this time, the cut body is cut open while passing through the guideline is spread to both sides to be transferred to the cutting part, the cutting part is moved to the front and rear is cut to a constant length while no folding occurs in the cutting part. .

Therefore, the sheath is peeled off by a simple cut to cause natural burst due to thermal expansion, and this thermal expansion zone is automatically stopped when the machine is stopped during work, especially when the thermal expansion zone is a high frequency. By heating only the iron core of the optical cable in a moment, there is no residual heat when the machine is stopped, which prevents damage to the coating. Also, the coating peeled off by thermal expansion is automatically peeled off by pulling the wire. No problem will occur.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 1, the method of stripping the sheath of the cable is first selected according to the thickness to allow automatic loosening while winding the sheathed cable divided by the same thickness. A first step of enabling accurate movement by the guide rollers to induce entry into the forward direction without being loaded by the entry rollers;

A second step of allowing the cable guided by the first step to move precisely while passing through the entry roller and the pulling roller to improve productivity;

A third step of forming a cut line on the cable moved by the second step;

A fourth step of thermally expanding the cable having the cut line formed by the third step while passing through the thermal expansion region for inducing peeling automatically by thermal expansion;

A fifth step of thermally expanding by the fourth step to induce the cover to be automatically opened;

A sixth step of separating the covering formed by the fifth step;

Peeling is carried out by cutting the coating formed in the sixth step.

Therefore, if only a simple cut line is formed on the sheath of the cable and heat is applied to maintain the thermal expansion, the cover is automatically opened by the cut line, so that the productivity can be controlled and accurate recycling can be easily performed.

As a device for this purpose as shown in Figures 2 and 3, the configuration of the present invention is a guide roller for enabling easy entry in the forward direction even when the angle of the entry direction is widened in the cable 100 of the coated state When passing through the (90) to enter the entry roller (80) through the pull roller (70) while cutting the blade holder portion 60 is equipped with a blade cut the cut line 51 to the sheath 50 of the cable 100 When the cable 100 is formed to pass through the thermal expansion region 40, the natural spreading is generated by the cut line 51 formed while the cover 50 is thermally expanded, so that the cable 100 is opened to the outside of the wire 101.

At this time, the guide roller is for easy entry by reducing the load even if the direction in which the cable 100 enters the entry roller 80 is not in the forward direction but in the lateral direction.

In addition, the covering 50 that is opened as described above is to be opened to the left and right around the electric wire 101, so that the cable 100 is wound when the wire 101 is peeled off with a rewinder (not shown). ) Can be automatically peeled off continuously.

At this time, the coating body 50 is opened to both sides while passing through the guide tube 30 and is transferred to the cutting unit 20, and the cutting unit 20 is cut into the cutting unit while moving back and forth to continuously enter the cutting unit. The losing coating is cut to a certain length while no folding occurs during cutting.

At this time, the heat generating means used as the thermal expansion region is possible by forming a heating path by a heater to directly inject heat to the coating.

However, in the case of using a heating furnace, the residual heat remains in the heating furnace even when the operation of the machine is stopped due to a defect, which may cause a problem in peeling off due to the melting or plasticization of the coating. There is a drawback of not being able to cut to length or precisely.

Therefore, when the thermal expansion region is used at a high frequency, the high frequency heats only the iron core of the cable when passing through the high frequency generator 10 so that heat is not transferred to the coating, so that the peeling due to the natural opening of the coating is easy. At the same time, when the operation of the machine is stopped, there is an advantage that the power is cut off immediately so as not to damage the coating.

This is because only the electric wire of the cable is heated when heated at a high frequency, so that the heat is transferred to the outside, so that the expansion of the coating occurs from the inside to the outside, thereby making it easy to peel off.
