Next, a structure of a slope forming device for surely preventing peeling by forming a taper of a tape T wound around a cable in a tapered shape will be described with reference to FIGS. 10 to 15. This device automatically performs a so-called slope formation in which the end of the tape winding in the cable connection portion is formed like the tip of a sword, and a catenary curve is ideal like the slope model 19.

As shown in FIG. 11, the startup switch 3 incorporated in the hand controller 302 pulled out from the control panel 301.
When 03 is closed, the control device in the control panel 301 operates and the motor 40 incorporated in the traveling platform 1 starts to rotate. However, since the clutches 12a, 12b, 12c are disengaged, the gears 10a, 10b and the driving gear 4 do not rotate. In order to set the rising rate of the slope model 19 according to the thickness of the winding tape T, the number of pulses corresponding to the thickness is set as a count input to the electronic counter 304 incorporated in the control panel 301. Motor 40 as an example
When the screw has rotated once, the internal thread 205a shown in FIG.
Assuming that the pulse is increased by mm, when the pulse generation disc 204 has 50 notches, the pulse is increased by 0.1 mm per pulse. Therefore, when the tape thickness is 0.5 mm, the number of pulses is set to 5. When the operation switch a of the hand controller 302 is closed, the device in the control panel 301 operates to operate the clutch 12
a and 12c are included. Therefore, the split gear 3 connected to the clutch 12c and the split rotating body 2 on which the tape T is set rotate while winding the tape T around the connecting portion of the cable. At the same time, the gear 10a rotates and meshes with the rack 11 to move the traveling platform 1 laterally. When the operation switch b of the hand controller 302 is closed, it moves to the opposite side.

The sensor 20 attached to the traveling platform 1 gradually approaches the slope model 19 and senses it. A signal is sent to the control panel 301 at the same time as the response, and a relay in the control panel 301 works to release the clutch 12a and the clutch 12b.
The gear 10b rotates and the traveling gantry 1 reversely moves. At the same time, a signal is sent to the electronic counter 304 and the motor 20
3 drives to rotate the screw shaft 205, and the female screw 205a
The slope model 19 attached to the slope forming body 17 via the ascends, and the position of the catenary curve 310 starts moving to a point where the sensor 20 is sensitive. Since the pulse generation disk 204 connected to the screw shaft 205 also rotates, the sensor 206 senses and emits a pulse, and the electronic counter 3
A pulse signal is sent to 04. The electronic counter 304 stops the motor 203 when the set pulse signal is reached. At that time, the position of the catenary curve of the slope model 19 rises to a position corresponding to the tape thickness and waits for the traveling gantry 1 which reverses and repays. As for each sensor on the opposite side, the tape winding having the same sectional shape as the slope model is laminated and formed by repeatedly reversing the traveling pedestal 1 as described above. Therefore, the slope model 19 moves by the reciprocating thickness of the wrapping tape, and if this device is installed on the left and right, the wrapping device automatically changes the sensitive position of the sensor 20 according to the movement amount of the folding slope model. In the figure, 208 is a guide rod to prevent the model mounting device 207 from swinging, 212 is an outer frame, and sensors 209 and 210 fixed to this are mounted to set a limit position at the time of maximum descent and maximum ascent, It is operated by the sensitive plate 211 arranged at the mounting position 207.

[Effects of the Invention] According to the present invention, different tapes can be freely used by changing the stretch ratio of each manufacturer, and the slope formation can be automatically rolled into a neat shape to smoothly wind the tape of the cable. It can be carried out.
