A first tape guide roller, a second tape guide roller, and two third tape guide rollers are provided in order in the attached tape feeding direction, and the two third tape guide rollers are vertically spaced apart and arranged in parallel to supply the tape. The tape feeding table is characterized in that the end of the vertical tape feeding side of the stand is placed below the group path line, and the tape supply stand is installed so as to be rotatable in the horizontal direction about the end.

The present invention will be explained with reference to the figures.

-e The rotary type wire stranding machine passes the insulated wire B fed out from the bobbin A through the wire guide C, arranges it in the wire concentrator, and collects it in the collection die E to form the cable core F. At the same time, the rotary winder Due to the rotation of G, the wires are twisted and the vertically attached tape 1
The winding material is then pressed and wound by a pressing winding head H, taken up at the bottom by a take-up capstan I, and wound onto a drum J provided in a rotary winding machine G.

Here, the longitudinally attached tape 1 is supplied by a tape supply device K according to the present invention.

The tape supply device rotatably supports a tape pad 3 on a picture-shaped tape supply table 2, and sequentially includes 1 tape guide roller, 4 tape guide rollers, and 5.2 second tape guide rollers in the feeding direction of the longitudinally attached tape 1. A third tape guide roller 6.6' is rotatably provided, and two third tape guide rollers 6.6' are rotatably provided.
6' are vertically spaced apart and parallel to each other, and in the illustration, the 6 axes of these are both horizontal and perpendicular to the pass line M of the vertically attached tape 1, and the cable pass line L
The vertically attached tape 1 is supplied diagonally from the horizontal direction toward.

Tape supply stand 2 (d) Place the end 1 of the longitudinally attached tape 1 in the feeding direction below the cable path line L, and install the tape feed stand 2 so that it can be rotated horizontally to a desired angle with the line end @7 as the center. did.

In the illustrated embodiment, a shaft 9 is installed in the installation tube 8 below the cable pass line L, and the pass line M of the longitudinally attached tape 1 is placed at the end @7 side of the bottom part 10 of the tape supply table 2 in the longitudinally attached tape feeding direction. A fitting @11 is recessed below the fitting part 11, and the shaft 9 is fitted into the fitting part 11, and if necessary, the end @12 of the bottom part 10 of the tape supply stand 2 on the tape pad 3 side is wheel 1
3 to make it easier to rotate the tape supply table 2 in the horizontal direction around the axis 9, by inserting the axis 9, and by using the wheels 13 together, and also to the left side of the goople pass line L. It is also rotatably installed on the right side.

In order to wind the vertical tape 1 right-handedly around the cable core F which is twisted right-handed by the rotary winding machine G, if the work side is on the right side as seen from the operator, it is necessary to wind it as shown in the solid line in Figure 2 and in Figure 3. The tape supply table 2 is positioned on the right side in the direction of movement of the cable core F, and the vertically attached tape 1, which is guided by the first and second tape guide rollers 4 and 5 in order, is fed out as shown in solid lines in FIGS. 2 to 4. The tape comes into contact with the lower side of the third tape guide roller 6 provided above, and is wound around the cable core F from above.

Alternatively, if the work side is to the left as seen from the worker, the tape supply stand 2 is positioned on the left side in the direction of movement of the cable core F as shown by the broken line in FIG. , 5, is brought into contact with the upper side of the lower third tape guide roller 6' shown by the broken line in FIG. 4, and is wound from the lower side of the goofle core F.
It can also be wound on the right side.

In order to wrap the vertically attached tape 1 on the left-handed cable core F in a left-handed manner, if the work side is on the right side as seen from the worker, as shown in FIG. The vertically attached tape 1 is positioned on the right side as shown by the solid line, and is guided by the first and second tape guide rollers 4 and 5 in order as shown by the broken line in FIG. It comes into contact with the upper side and is wound from the lower side of the goofle core F, so that it is wound to the left.

Alternatively, if the work side is to the left as seen from the worker, the tape supply stand 2 is positioned on the left side in the direction of movement of the cable core F as shown by the broken line in FIG. As shown in the solid line in FIG. 4, the vertical guide upper 1, which has been guided by the cable core It can be wrapped around a roll.

When the longitudinally attached tape 1 has a fixed front and back side, when it is rolled to form the tape pad 3, if the front and back sides are facing inside or outside, the tape pad 3 should be fed out as shown by the solid line in Figure 4. Depending on whether the tape pad 3 is fed out from above or from the bottom as shown by the one-dot chain line, it is possible to select whether the tape pad 3 should be turned upside down.

As described above, the tape supply device of the present invention is provided with the tape supply table 2 with the end 7 of the longitudinally attached tape 1 in the feeding direction placed below the cable path line L, and the tape supply table 2 is provided with a
11th and 2nd tape guide rollers 4 provided sequentially in the feeding direction of the longitudinally attached tape 1 fed out from the tape pad 3
. Since the cable core F, which is being twisted by the rotation of the rotary winder G, is wound onto the cable core F, even when the direction of rotation by the rotary winder G is reversed, the position of the tape supply table 2 is adjusted to the cable path line. By changing the above-mentioned abutment to the upper and lower third tape guide rollers 6 and 6' to a tilting position, the feeding position of the vertically attached tape 1 is fixed on the machine work surface without changing to the left and right sides of L. The longitudinally attached tape 1 can be wound according to the rotation of the rotary winder G, and the winding work can be easily monitored.

Of course, in order to view the twisted wire work as a right-hand flow from the worker's point of view, as a left-hand flow, the position of the tape supply stand 2 must be changed to All you have to do is move it to the left side of line L as shown by the chain line.

This makes it easy and efficient for a worker standing between the parallel winding and rotating type wire twisting machines to monitor the winding operations of the wire twisting machines on both sides.

In addition, in the device of the present invention, even if the longitudinally attached tape 1 has two sides, it can be easily turned both sides by supporting it on the tape supply table 2 with the tape pad 3 facing upward and downward. .

In the first place, the vertically attached tape that is wrapped around the stranded wires of a communication cable is wrapped with an appropriate overlap to prevent the stranded wires from melting due to heat during the outer coating process, but in communication or one pull, it is necessary to Since the outer diameter of the cable changes depending on the number of wires and the number of cores accommodated, the pitch of the twisted wires and the width of the longitudinally attached tape must be changed accordingly.

Adjusting the winding angle of the longitudinally attached tape in accordance with the cable diameter, strand pitch, and longitudinally attached tape width is an important condition for the tape supply device of the present invention.

In the present invention, the tape supply stand 2 is installed so as to be freely rotatable in the horizontal direction around the end 7 in the longitudinal tape feeding direction, so the tape supply stand 2 can be rotated horizontally as needed around the end 7. The winding angle of the vertically attached tape can be adjusted by moving the vertically attached tape.

In this way, the present invention not only allows the winding angle of the vertically attached tape to be easily adjusted by horizontal rotation around the end 7 of the tape supply table 2, but also allows the rotation of the rotary winding machine G to be easily adjusted. Regardless of the direction, the twisted wire work from the perspective of the worker can be done regardless of the flow direction.
It is easy to wind the longitudinally attached tape 1 according to the rotation of the twisted wires, and it is extremely useful as a tape feeding device for a communication cable twisting machine.
