Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of a continuous winding device for flat cables, particularly a winding device that automates the fixing of cable ends to a cable drum. .

[Prior art] When the drum becomes fully wound during continuous winding of a flat cable, the flat cable is stored in an accumulator, etc., and during this time, the drum is replaced with a new empty drum, and winding is started again. Ru.

In this case, the end of the flat cable must be fixed to the body of the empty drum before winding begins, but conventionally, the end of the cable was fixed to the drum body using adhesive tape. It is being done.

[Problems with the prior art] However, fixing cable ends using adhesive tape requires operations such as cutting the adhesive tape, detecting the cable end, and pasting the adhesive tape, so it takes a long time. , ancillary equipment such as an accumulator to cope with this time becomes large-scale. Therefore, in the case of a continuous winder, there are time and equipment problems.

[Objective of the invention] An object of the invention is to provide a continuous winding device that can automatically wind up a cable onto a drum without requiring fixation of the cable end portion with adhesive tape.

[Main points of the invention] The continuous winding device of the invention includes a first cable guide that moves close to the body diameter of the cable drum to form a narrow space between the cable drum and the body diameter at the start of winding, and a second cable guide. Cable guides are installed so as to sandwich the cable drum, and the flat cable is attached to the first or second cable guide at a position where the flat cable is wound around more than half the circumference of the body along the narrow space. It is characterized in that it is configured with a roll that is pressed against the radial portion of the body.

[Function] That is, the tip of the flat cable advances along the narrow space formed by the body diameter and the first and second cable guides, and the cable guide closes at the position where it is wrapped around the body diameter more than half a circle. The slack of the flat cable is absorbed by being pressed against the body diameter by the roll provided at the top, and the tip is sandwiched between the flat cable itself and the body diameter, making it possible to wind it up. It will become.

[Embodiment] Next, an embodiment of the winding device of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an overall explanatory diagram of the winding device, and FIGS. 2 and 3 are explanatory diagrams of the operation at the start of winding.

In Figure 1, 1 is a flat cable, 2 is a pinch roll, 3 is a cable cutter, 4 is a cable drum, 5 is a first cable guide, 6 is a second cable guide, 11 and 12 are cylinders. .

When the cable drum is fully wound, the flat cable 1 is cut by the cutter 3 and the rotation of the pinch rolls is also stopped. While the rotation of the pinch roll 2 is stopped, the flat cable 1 is stored in an accumulator (not shown).

When the installation of the cable drum 4 is completed, the cylinders 11 and 12 are operated to move the first cable guide 5 and the second cable guide 6 to near the body diameter part 8 of the cable drum 4 (the second
Figure). At this point, the pinch roll 2 is rotated and winding of the flat cable 1 is started. Note that at this time, the feeding speed of the flat cable 1 by the pinch rolls 2 is faster than the feeding speed of the flat cable 1, and during this time, the flat cable 1 stored in the accumulator is fed out.

The first cable guide 5 and the second cable guide 6 each have guide surfaces 9 and 10 having approximately the same curvature as the body diameter portion 8, and the flat cable 1 fed from the pinch roll 2 is It travels along the narrow space between the trunk diameter section 8 and the guide surfaces 9 and 10, and goes around the trunk diameter section 8. However, the trunk diameter part 8
Since there is a gap between the flat cable and the guide surfaces 9 and 10, the flat cable becomes slack and cannot be wound up.

Therefore, a cable presser 7 is provided on the guide surface of the second cable guide 6 to press the flat cable 1 against the body diameter part 8, and when the flat cable 1 is wound while being pressed against the body diameter part 8, the slack is absorbed. and winding is possible.

That is, as shown in the enlarged view of FIG. 3, when the flat cable 1 is wound more than half the way around the body diameter part 8 and pressed by the cable pressing roll 7, the flat cable 1 is wrapped around the body diameter part 8 and pressed by the cable pressing roll 7. The tip portion is sandwiched between itself and the body diameter portion 8, making it possible to wind it up.

After the start of winding, the first and second cable guides 5 and 6 are moved to the outside of the cable drum 4 by operating the cylinders 11 and 12, and wait until the next operation).

In this way, winding of the flat cable after the cable drum is replaced is automatically started, eliminating the need to fix the end with adhesive tape, and greatly improving work efficiency.

[Effects of the Invention] As described above, according to the present invention, it becomes possible to reliably perform terminal processing during continuous winding of a flat cable, and winding onto a drum can be performed automatically. As a result, cable terminal processing can be carried out in a short time, so that the size of incidental equipment can be reduced.
