Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a fiber laminate for resin reinforcement.

More specifically, the present invention relates to an apparatus capable of efficiently and high-quality manufacturing a laminate in which sheet-like threads are arranged in an oblique manner on a fabric, that is, a bias laminate.

Bias laminates have traditionally been used as a base material for fiber reinforced resin (FRP), with excellent strength, isotropy, and thread rigidity.
It is necessary to make the laminate run diagonally with respect to the direction of travel and to arrange it neatly.A known method for this purpose is to hook parallel yarn sheets alternately to left and right tenter belts and fold them. However, in this method, the apparatus was complicated and complicated, and the manufacturing operation was extremely difficult. That is, 1.4 to 2
It is necessary to prepare a thread sheet with a width of 0 times.

The swinging motion and reversing motion are extremely slow, and the oblique motion of the threads and the mechanism for taking out the sheet are complicated to operate.The present invention solves these drawbacks and provides stable The present invention provides an apparatus for efficiently manufacturing a laminated material without unevenness in force and force through operations such as A device for rotating the threads and arranging and stacking the threads in an oblique manner with respect to the fabric, which is provided with means for rotating and feeding the threads, and means for stacking the threads and the fabric, gripping and taking them off, and , a yarn arrangement characterized in that, as a means for rotating and feeding the yarn group, a yarn guide means that performs the function of conveying two rows of yarn facing each other, and an end conveying means consisting of a gear are provided. It is a device.

In the present invention, the means for rotating and feeding the yarn group comprises at least a means for attaching a creel or buff cage for the yarn, and a yarn guide means.

These rotate around the direction in which the yarn travels. By this means, the sheet-like yarn groups are folded and laminated. Further, since the yarn group is supplied as two rows of sheets facing each other, the two rows of sheet-like yarns are laminated in a state of crossing each other. Therefore, for the fabric to be supplied in a later process, the threads are arranged in a diagonal direction with respect to the direction in which the fabric travels, and also in two directions.
It is made by laminating sheets of yarn in a crossed manner.

Next, the apparatus of the present invention will be explained using the drawings.

Figures 1 to 5 are other process diagrams used to explain the present invention, and Figures 4 and 5 are model diagrams showing the device of the present invention.In Figures 1 to 5, the package yarn is Attached to the beam 1 - The beam 1 is installed on the frame 6, and the frame 6 is rotated by the rotation shaft 42 and the rotation mechanism 5. The yarn group row 7.8 let out from the beam 1 passes through the guide group row 2.3 and is held by a gripping means, for example, a nip roller 10.
The beam 1 and the guide group row 2.degree. 3 are rotated in the one-foot direction, so the nip above the nip roller 1.degree. At 15, the supply system rows 7.8 are folded and stacked diagonally on top of each other as shown in FIG.

In Figure 3, the solid line indicates the yarn on the near side.

The dotted line indicates the thread on the opposite side.The sheet 13 in which the threads are laminated in the diagonal direction and in the cross direction with respect to the fabric 9 in this way is sewn by a sewing device having an integrating means 0, for example, a needle 11 and a hook 12. integrated by. The integration means may also include applying an adhesive, processing using a hot melt adhesive and a hot roller, etc. In the above sewing process, the sheet is pressed and gripped with nip rollers 10° and 14 to apply tension. Easy to operate - Next, the device of the present invention will be explained based on Fig. 4.5. The part below 10 is omitted because it is the same. Figure 4 is a side view of the yarn guide means to the nip roller, and Figure 5 is a top view of the yarn guide means.
In Fig. 4.5, the yarns 7 and 8 are bent in direction by a fixed guide 21 while being applied with tension, and a yarn guide means 1, for example, spiral rollers 23 and 24, has the function of transferring yarns in two rows facing each other. is transported in a certain direction by Introduce the yarn into the valleys of the spiral rollers 23° and 24,
By rotating the roller, the yarn can be transported in a certain direction. At the reversal part of the yarn, that is, at the end of the sheet-like yarn, where the opposing yarn groups are moved in opposite directions,
The fixed guide 210 width becomes narrower.

and matched. Therefore, the yarn group row 7.8 near the end
The force of pushing into the trough of the spiral roller becomes weaker, and it enters the trough of the gear 27 disposed at the end, and as the gear rotates, it is transferred to the opposite row. Tension is then applied at the increasing width of the fixed guide 21, which moves to the trough of the spiral roller, along which the movement progresses.

Therefore, the yarn group 7.8 is formed in a cross pattern on the nip roller 10 and is laminated on the fabric.Note that the thread 27 indicates the rotation center of the gear 22.In addition, in the present invention, the yarn guide means in the straight portion is I used a spiral roller as one method.

Other known means may also be used, such as a guide row attached to a pair of linearly moving chains.

Further, as a gear-shaped end portion conveying means in the present invention.

The gear shape can be any shape, l! It only needs to have a thread sending function.

In the present invention, yarns include glass fibers, carbon fibers, silicon fibers, polyester fibers, polyamide fibers, aromatic polyamide fibers (including polyaramid fibers), and wholly aromatic polyester fibers.

Other known reinforcing fiber materials are shown. Further, these reinforcing fiber materials may be composed of a single type.

It may be constructed by combining various materials. Also.

It is more preferable that such a material can also be used as a seam thread, which is the integrating means of the present invention. The reinforcing fiber material is a filament or a staple fiber.

Any material may be used as long as it exhibits a uniform fiber shape. In the case of using staple fibers, etc., twisting yarn is used.The fabric in the present invention may be any known fabric such as woven fabric, II material, or non-woven fabric. Among these, particularly preferred fabric is woven fabric.This may be in the vertical or horizontal direction. This is because the strength of the fabric is the highest, and the strength of the fabric structure is the highest.Also, glass fiber and carbon fiber.

This is because, among silicon fibers, woven fabrics are the easiest to process and have good handling properties.

Next, the effects of the present invention will be explained.

According to the present invention, it is not necessary to thread the thread through the guide hole as shown in FIG. 2, and it is easy to start the work or restart the thread when the thread breaks. Furthermore, since the sheet-like yarn group can be moved horizontally very easily, it can be carried out at high speed, and therefore, it can be manufactured with high efficiency. In addition, even materials with poor processability that cannot be made into textiles can be used as laminated reinforcing materials.Furthermore, since high tension can be applied to the threads to arrange them, the arrangement is extremely uniform and the thickness is even.・Compared to other conventionally used fabrics, it is possible to obtain a laminate with a small porosity, so 1.
The strength utilization rate can be increased, and a laminate with excellent delamination resistance can be obtained.

The present invention will be explained in detail below with reference to Examples.

Example 1 A 1500 denier (150 fl) polyester filament was sized and made into 100 parallel sheet-like bee AK devices.
I arrived. Then, it was mounted on the rotating frame shown in FIG. 1, passed through the fixed guide 21 and spiral rollers 23 and 24 shown in FIG. 5, and set. The outermost diameter of the spiral roller is 50m
