Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a parallel tape group alignment mechanism that aligns each tape in a feeding path, and in which a horizontal tape group is aligned with a longitudinal tape group that is sequentially fed. It can be used in a device that produces a lattice-like web by pulling out in cross directions and fusing the intersecting portions of each other.

[Background technology]

Some of the recent synthetic resin materials exhibit extremely high strength only in specific directions, and when using such highly directional materials in sheet form, it is necessary to ensure strength in two directions along a plane. There is a need to. For this purpose, in addition to making the material into a film and laminating them so that their strength directions intersect, the material is shaped into a long and thin tape that extends in the strength direction, and the resin tapes are stacked together. The webs are arranged crosswise to form a grid-like web.

Here, in manufacturing a lattice-like web from such a resin tape, conventionally, a method of weaving the web using a loom has been common. However, when a loom is used, a so-called shuttle feeds the horizontal tapes one by one between the longitudinal tapes, so the basic operating speed is slow, and there has been a need to improve manufacturing efficiency.

In contrast, the present applicant has proposed an apparatus that produces a lattice-like web not by weaving a resin tape but by high-temperature fusion using the thermoplasticity of the resin material.

This device forms a vertical tape group by arranging a plurality of resin tapes in parallel at predetermined intervals, and pulls out a similar horizontal tape group in a cross direction with respect to the vertical tape group, and removes the mutually intersecting parts. The tape is fused using a high-temperature press, the horizontal tape groups are separated, and the vertical tape groups are sequentially fed to wind the lattice web in the vertical direction. Since this is not necessary, the work speed is fast and extremely efficient manufacturing is possible.

[Problem to be solved by the invention]

By the way, in the above-described fusion-type lattice web manufacturing apparatus, the steps of pulling out a group of horizontal tapes, fusing them, and cutting them are repeated in sequence.

Here, in performing fusion, it is necessary that the resin tapes that intersect with each other are in uniform contact with each other at their intersection points.
It is necessary to take into consideration the tension, posture, etc. so that the plurality of tapes in each tape group are stretched in a similar manner.

In addition, in a group of horizontal tapes that are pulled out and cut in sequence, the tip portions are released as they are cut, so the tip position of each tape may shift or the tip portion may be twisted or warped. It was difficult to securely lock the tip of each tape when pulling it out.

For this reason, alignment adjustment is required manually at any time along the feeding path of each tape, and the drawing process also needs to be performed manually. However, it is not possible to obtain consistent results manually, and it is not preferable in terms of work efficiency or safety such as burns during fusion heating, so there is a need to develop a kill mechanism or device to automate these operations. It was getting worse.

An object of the present invention is to provide a mechanism for aligning a group of parallel tapes, which can ensure the alignment of a plurality of tapes sent in parallel, and can also align the leading ends even when they are cut and fed sequentially.

[Means to solve the problem]

The present invention is an alignment device arranged in a feeding route for a tape group made up of a plurality of tapes arranged in parallel at predetermined intervals, and is arranged in the width direction of the route to guide the tapes in alignment at predetermined intervals. It is provided with a guide means and a pressing roll arranged along at least one guide means and parallelizing each tape in contact with the circumferential surface. Further, the above-mentioned guide means and presser roll are provided as an alignment device disposed on the feeding path of the group of parallel tapes that are pulled out by a predetermined amount and cut in the width direction, and are disposed near the position where the tapes are cut. A pressing member is provided to hold each tape.

[Effect]

In the present invention, each tape of the parallel tape group is accurately maintained in its position and mutual spacing while passing through the guide means, and the surface of each tape is maintained accurately while passing through the presser roll. They are maintained in one plane following the circumferential surface of the roll, and are aligned in parallel at predetermined intervals. Further, in a group of tapes that are pulled out by a predetermined amount and cut in the width direction, the leading ends of each tape are held in a constant alignment by being held by a pressing member near the cutting position. Accordingly, the parallel tape groups are maintained in alignment at each section of the path, cut section, etc., thereby achieving the above objective.
