Description

[Detailed description of the invention] The present invention relates to an automatic tape jointing device.

To supply vertical tape for cables, etc., prepare two tape suppliers, and when the remaining amount of the preceding tape reaches zero, join the starting end of the tape of a new tape pad to the ending end of the preceding tape. The tape can be continuously supplied.

Conventionally, the above-mentioned tape joints were manually performed by workers, which was inefficient.

The present invention has been made based on the above circumstances, and provides an automatic tape jointing device that can automatically join the trailing end of a preceding tape and the beginning of a trailing tape.

The invention will be explained in detail below with reference to the drawings. In FIG. 1, the tape supplier 1 is constructed by attaching tape pad holders 4 and 5, respectively, at symmetrical positions with respect to the axis 2 of a substrate 3 attached to the axis 2 so as to be click-stopped at every 180 degrees. FIG. 1 shows a state in which the starting end of the tape 7a of the tape pad 7 mounted on the holder 5 is connected to the end of the leading tape 6, and the tape forms a horizontal running path between the guide rollers 8 and 9 and passes through the accumulator 10. The tape is then sent to, for example, a tape longitudinal attachment device (not shown).

Above the horizontal track is the first vacuum chuck 11.
is provided. A valve 13 is provided in the exhaust pipe 12 of this chuck.

Also, below the horizontal running path, second and third vacuum chucks 14 and 15 are provided in parallel in opposition to the first vacuum chuck 11. Further, the exhaust pipes 16 and 17 of these chucks are provided with valves 18 and 19, respectively.

Furthermore, between the second and third vacuum chucks, there is a cutter 20 that moves up and down at a timing that will be explained later.
is provided.

Further, the third vacuum chuck 15 on the tape sending side is configured to be able to move up and down at timings to be explained later.

Furthermore, a tape pad holder 4,
Tape break detectors 21 and 22 are provided opposite to 5.

In addition, each tape pad holder 4, 5 is attached to the substrate 3.
When rotating, each vacuum chuck 11, 14, 1
It is possible to retreat to a position where it does not interfere with 5.

In the apparatus of the present invention having the above configuration, the tape joint is performed as follows. First, attach a new full tape pad 23 to the upper tape pad holder 4, and then pull out the tape 23a.
The starting end of the tape is attached to the single-sided adhesive tape 24 which is adsorbed onto the first vacuum chuck 11 with the adhesive side facing down. At this time, the starting end of the tape 23a is positioned between the second and third vacuum chucks 14 and 15.

Suppose now that the tape break detector 22 detects a tape break in the tape pad 7 on the tape pad holder 5. Then, based on this detection output, the exhaust pipe 1
Valves 18 and 19 of Nos. 6 and 17 are opened, and the second and third vacuum chucks 14 and 15 suction and grip the tape running on the horizontal running section. Here, the cutter 20 is raised and the tape is cut. Next, as shown in FIG. 2, the third vacuum chuck 15 is raised and the adsorbed cut end of the tape is pressed against the adhesive tape 24 held by the first vacuum chuck 11 to adhere it. As a result, the starting end of the tape 23a of the new full tape pad 23 and the ending end of the preceding tape 6 are jointed by the adhesive tape 24.

Here, each vacuum chuck 11, 14, 1
If the tape adsorption state due to the vacuum in step 5 is released, the tape will start running. Note that during the above-mentioned joint period, the tape is fed out from the accumulator 10, so there is no risk of interfering with the vertical attachment work or the like.

In addition, the operation of the second and third vacuum chuck cutters, the raising and lowering of the third vacuum chuck, and the release of the vacuum after the lowering are performed by the detection output of the tape break detector described above. This is done by a control means that automatically performs a series of operations.

Next, the board 3 is rotated 180 degrees to bring the now empty tape pad holder 5 to the upper position, and a new full tape is attached to it, and it is prepared for the next tape joint in the same manner as described above.

As is clear from the above, since the apparatus of the present invention can automatically perform tape joints one after another, it is extremely advantageous in saving labor in this type of work.

Note that the present invention is not limited to the above embodiments. For example, if the tape pad is large enough and the tape length required for the work is only two tape pads,
The two tape pad holders may be fixed in position without being provided on the indexable substrate.
In this case, it goes without saying that the tape break detector only needs to be provided for the lower tape pad holder.

Claims (1)

[Claims] 1. Two tape pad holders arranged above and below, a pair of guide rollers that form a horizontal running part on the running tape that is pulled out from the tape pad on the lower tape pad holder, and a tape exit of the guide roller. an accumulator that can be attached to the side; and a first vacuum chamber that is provided on the upper part of the horizontal running section and that attracts the single-sided adhesive tape with the adhesive side always facing downward, together with the tape terminal pulled out from the upper tape pad that is adhered to the adhesive side. a vacuum chuck, second and third vacuum chucks provided below the horizontal run, facing the first vacuum chuck and parallel to each other in the tape running direction; and between the second and third vacuum chucks. a cutter provided on the tape pad holder located below, a tape break detector that detects a break in the tape pad on the tape pad holder located below, and a detection output of the tape break detector to detect the second and third vacuum chucks. The system automatically performs a series of operations such as setting the tape in a suction state, then operating the cutter, raising and lowering the third vacuum chuck on the accumulator side, and releasing the tape suction state of each vacuum chuck after the lowering. 1.
