Description

Fabric-type composite material sheet manufacturing method and manufacturing apparatus, and fabric-type composite material sheet manufactured thereby

The present invention relates to a method for manufacturing a composite material sheet in the form of a woven fabric, and more particularly, it is possible to improve the production speed and production stability of the composite material sheet in the form of a woven fabric, and minimize the weaving interval of the composite material sheet in the form of a woven fabric It relates to a method for manufacturing a composite material sheet in the form of a fabric, which can effectively prevent the separation of the outermost warp and outermost weft while still doing so.

Thermoplastic composite materials are manufactured into parts after being manufactured into various types of intermediate materials according to manufacturing methods.

The starting point of the thermoplastic composite material is Long Fiber Reinforced Thermoplastic (LFT), a long fiber reinforced thermoplastic resin, which is manufactured in the form of pellets by impregnating the base resin with reinforcing fibers. to mold

The material produced by LFT one step further is UD Tape.

UD Tape is an abbreviation of Unidirectional Tape. Unlike general injection materials and LFTs, the reinforcing fibers inside the material are not broken and are oriented continuously, so higher physical properties can be realized compared to LFTs. Therefore, from this material onwards, it is called continuous fiber reinforced thermoplastic plastic composite material.

Although this material has a manufacturing and molding method that is more difficult than the injection material, it can reproduce the performance of the reinforcing fiber as it is during molding into parts and has very good mechanical properties, so it can replace metal in various parts. It is in the spotlight as a key material for weight reduction.

Going one step further, slitting the yudi tape and reprocessing it into a narrow and uniformly slitted uddy tape, and then weaving it, a woven type composite sheet ) is made with

This fabric-type composite material sheet is formed into a product in parallel with the U-D tape, and is mainly applied as the outermost layer to products where the appearance and emotional quality of the product is important. In addition, when a weave type material is applied, compared to a single application of UD tape, the reinforcing fibers have a structure in which the reinforcing fibers are entangled and mutually constrained. It can be applied to parts.

The core processes required in the process of manufacturing the composite material sheet in the form of a fabric are slitting and weaving of the UD tape, and various types of weaving technologies are being developed.

By the way, for example, in the conventional method for manufacturing a composite material sheet in the form of a fabric disclosed in Korean Patent Registration No. 10-0822409, the process of inserting the weft tape is made in a rapier type.

In this method, the device in the form of tongs penetrates into the space created by the vertical movement of the warp tape, grabs the weft tape on the other side and returns it again. There is an advantage of stably inserting the weft tape, The clamp device has a problem in that durability is weak due to repeated reciprocating drive because the minimum length of the weft tape must be reciprocated whenever the tongs tape is input, and the production speed is slow as the time taken for the reciprocating drive There is this.

Also, since there is no device that can act as a guide when the udi tape is fed from the creel to the device as the warp tape, the lengths of the warp tapes cross each other and there is a risk of single yarn. Since the force that can restrain each other between the weft tape and the warp tape is only the frictional force due to the entanglement with each other, the outermost weft tape and the outermost warp tape have a problem in that they are easily separated from the composite material sheet in the form of a woven fabric. .

It serves to temporarily weld the material sheet 700 by pressing and cooling it.

On the other hand, the winding winder 1000 serves to finish the manufacturing process of the composite material sheet in the form of a fabric by winding the sheet 700 of the composite material in the form of a fabric.

Hereinafter, a method for manufacturing a woven type composite sheet according to an embodiment of the present invention, made by an apparatus for manufacturing a woven type composite material sheet having the above-described structure will be described.

As shown in detail in FIG. 1, the method for manufacturing a woven type composite sheet according to an embodiment of the present invention includes a step (S0) of preparing a warp tape and a weft tape, and a warp yarn (絲絲). , warp) step of putting the tape (S1), the step of putting the weft (緯絲, weft) tape (S2), the step of forming the fabric (S3), and the step of fixing the shape of the fabric (S3b) And, winding the fabric (S4).

First, the step (S0) of preparing the warp tape and the weft tape includes a step (a) of slitting the UDI tape and a step (b) of mounting the slitted UDI tape on a creel.

The step (a) of slitting the UD tape is, as shown in FIG. 3 , arranged to be spaced apart from each other at a predetermined interval and rotated in parallel with the moving direction of the UD tape 100 for slitting the UD tape 100 It is a step of slitting the udi tape 100 to a predetermined width by a plurality of slitting knives 120 .

According to the setting of the slitting knife 120, the UD tape can be slit at a desired interval without damage, and at this time, the width of the slitted UD tape 110 may be 9 mm to 10 mm, but the present invention is here is not limited to, it may be provided in a width of various sizes according to the use and size of the composite material sheet in the form of a fabric.

Since the slitted UD tape 110 is wound in a roll shape and used in the following process, the slitted UD tape 110 will be simply referred to as a UD tape hereinafter.

In the step (b) of mounting the Yudi tape, the Yudi tape is mounted and the slitted Yudi tape is mounted on the creel 300 supplied to the fabric-type composite material sheet manufacturing apparatus, but the width of the composite material sheet of the fabric type is determined in advance. It is a step of mounting with a plurality of inclined tapes 200 to fit.

As shown in FIG. 4, a plurality of warp tapes 200 (see FIG. 2) are mounted on each Krillec unwinder 310 in a roll form to fit a predetermined width of the composite material sheet in the form of fabric, and then As the warp tape 200 is released from the Krillec unwinder 310, it is fed into the woven sheet manufacturing apparatus.

At this time, if the tension of the warp tape 200 is not maintained at a certain level or more due to the vertical movement of the heald 500 to be described later and is loosened, the weft tape 600 is caught on the warp tape 200 during input, which may cause a problem. Therefore, it will be possible to assist in maintaining the tension of the inclined tape 200 by using rotational friction in the Krillec unwinder 310 or by using a spring or the like.

On the other hand, in the step (S1) of putting the warp tape in, the warp tape 200 is formed by passing a UD Tape (Unidrection Tape) through the healing 500 that forms an aperture of the inclination by up-and-down motion. As the inputting step, the inclined tape guide step (S1a) and the inclined tape tension adjustment step (S1b) are included.

In the inclined tape guide step (S1a), when the plurality of warp tapes 200 mounted on the creel 300 are put into the fabric-type composite material sheet manufacturing apparatus, the plurality of warp tapes 200 are prevented from being tangled with each other. This is a step guided by the inclined tape input guide 220 .

At this time, as shown in FIGS. 5 and 6 , the position of the inclined tape 200 released from the Krillec 300 is first guided by the Krillec internal inclined tape guide 210 , and the inclined tape 200 is first guided. Since it is guided once again by the inclined tape input guide 220 while being inserted, it is possible to accurately guide the respective positions of the plurality of inclined tapes 200 to prevent entanglement or interference between the inclined tapes 200 .

That is, the inclined tape 200 passes through the seed light through the inclined tape input guide 200 in order to prevent entanglement with each other.

The inclined tape tension adjustment step (S1b) is a step of adjusting the tension of the inclined tape 200 by the inclined tape tensioner 400 provided on one side of the inclined tape input guide 220 .

As described above, if the tension of the warp tape 200 is not maintained at a certain level or more due to the vertical movement of the heedstone 500, which will be described later, and is loosened, the weft tape 600 is caught in the warp tape 200 during input. Because it can be caused, the tension of the inclined tape 200 is adjusted just before the inclined tape 200 passes through the heed light 500 .

That is, when the opening is formed by the vertical movement of the seed light 500 , each inclined tape 200 is inclined at a certain angle from the horizontal. You will be able to keep the status quo.

Here, the inclined tape tensioner 400 includes a plurality of tension rolls (see FIG. 2 ) for adjusting the tension of the input inclined tape 200, and a tensioner guide (410, see FIG. 7) disposed between the plurality of tension rolls. And, as shown in detail in FIG. 7 , the tensioner guide 410 includes a plurality of guide pins for guiding the positions of the plurality of inclined tapes 200 .

That is, the warp tape passes through the seed light with the warp tension adjusted through the tension roll.

On the other hand, the step of introducing the weft tape ( S2 ) is a step of introducing the weft tape 600 in a direction intersecting the warp tape 200 when an opening of the warp is formed by the vertical movement of the seed light 500 . This is a step of inputting a predetermined length by a push method in which the 600 is pushed in a direction intersecting with the inclined tape 200 from one side of the inclined tape 200 .

As described above, the process of inserting the weft tape in the conventional method is a rapier type in which the tongs-type device penetrates into the space created by the vertical movement of the warp tape and grabs the opposite weft tape and returns it again. Therefore, the clamp device has a problem in that durability is weak due to repeated reciprocating drive because the minimum length of the weft tape must be reciprocated every time the weft tape is input, and the production speed is slow as the time taken for the reciprocating drive has a problem.

Therefore, according to the present invention, it is possible to improve the production speed and production stability of the composite material sheet in the form of a fabric by inputting the weft tape by the push method.

The step (S2) of inputting the weft tape includes a weft tape input path forming step (S2a), a weft tape push entry step (S2b), a weft tape guide step (S2c), a weft tape cutting step (S2d) and , including a weft tape restraining step (S2e).

In the weft tape input path forming step (S2a), the warp tapes 200 disposed adjacent to each other are spaced apart from each other in the vertical direction by the heed light 500 for vertically cross-moving a plurality of warp tapes 200 whose tension has been adjusted. This is a step of forming a weft tape input path into which the tape 600 is input.

Here, as shown in detail in FIGS. 8 and 9 , the through-holes of the seed light 500 through which a plurality of inclined tapes 200 are disposed are formed to form a predetermined angle with respect to the input plane of the inclined tape 200 , , due to the shape of the through hole of the heap 500, the plurality of inclined tapes 200 are moved up and down in a state inclined at a predetermined angle with respect to the input plane of the inclined tape, so that the plurality of inclined tapes 200 are It is possible to move up and down without contacting the weft tape guide pin.

That is, when the plurality of warp tapes 200 move up and down while forming a predetermined angle, the width becomes narrower than when in a planar state, so that the width of the warp tape 200 is greater than the interval between the weft tape guide pins 620. It is possible to solve the problem that the warp tape 200 is pinched in the weft tape guide pin 620 during the vertical movement of the healing 500 even if it is input at the same level, and the weft tape input path is not formed properly, and furthermore, the weft tape By solving the limitation in widening the width of the warp tape 200 due to the volume of the guide pin 620 itself, the gap between the warp tapes 200 of the composite material sheet in the form of a fabric is basically minimized or It is possible to prevent a gap from occurring.

The weft tape push entry step (S2b) is a step in which the weft tape 600 is pushed through the weft tape input path and is placed in contact with the upper and lower sides of the weft tape 600 to push the weft tape 600 by rotation. Giving may be made by a weft tape push roller (not shown).

However, the present invention is not limited thereto, and the weft tape 600 may be entered while pushing the weft tape 600 using various types of devices as well as the weft tape push roller.

By using a device such as a weft tape push roller (not shown) that pushes the weft tape 600 in this way, the weft tape is input by the push method to improve the production speed and production stability of the composite material sheet in the form of a fabric do.

In the weft tape guide step (S2c), the weft tape 600 entering the weft tape input path is moved from the weft tape input path by the plurality of weft tape guide pins 620 respectively disposed between the plurality of warp tapes 200 . This is a step to guide you not to deviate.

Here, the weft tape guide pin 620 is, as shown in detail in FIGS. 9 and 10, a plurality of weft tape guide pins 620 are spaced apart from each other by a predetermined distance to form a weft tape guide 610, , each of the weft tape guide pins 620 are respectively disposed between the plurality of warp tapes 200 .

That is, the weft tape 600 is fed through a plurality of weft tape guide pins 620 respectively disposed between the warp tapes 200 .

The weft tape cutting step ( S2d ) is a step of cutting the weft tape 600 , which has been disposed between the plurality of warp tapes 200 .

At this time, the end of the weft tape 600 passing through the weft tape input passage 622 of the weft tape guide pin 620 is cut to have an inclined shape at a predetermined angle, thereby the weft tape 600. Since the scissors can more easily pass through the weft tape input passage 622, it is possible not to deviate from the weft tape input passage.

The weft tape restraining step (S2e) is a step of binding the cut weft tape 600 by a beater 640 to one side of the composite material sheet 700 in the form of a fabric (refer to FIG. As shown, by adhering the weft tape 600 to the warp tape 200 side by the beater 640, it is possible to minimize the weaving interval of the composite material sheet 700 in the form of a woven fabric.

After the weft tape 600 introduced through these steps is constrained, the constrained weft tape 600 moves according to the movement of the warp tape 200 , and a space is formed in which a new weft tape 600 can be inserted. do.

Meanwhile, the step of forming the fabric (S3) is a step of repeatedly inserting the weft tape (S2) is performed, and is a step of forming the composite material sheet 700 in the form of a fabric.

That is, as shown in detail in FIG. 2 , the warp tape 200 moves from the left to the right, and the weft tape input path is formed by the seed light 500 , and the weft tape 600 is formed in the formed weft tape input path. When input and constrained, the constrained weft tape 600 moves to the right, and a new weft tape input path is formed by the heald 500, and the same process is repeated, eventually resulting in a composite material sheet in the form of a fabric (700, see FIG. 12) will form

On the other hand, the step of fixing the shape of the fabric (S3b) is a step of fixing the shape of the fabric by adhering the outermost warp tape located at the edge of the fabric to the inner direction of the fabric by the separation prevention roller 710, melting and cooling, It includes a separation prevention treatment step, a melting step, and a pressure cooling step.

In the separation prevention treatment step, a plurality of weft tapes 600 are sequentially put in and the outermost warp tape disposed on the outermost side of the composite material sheet 700 in the form of a fabric, the outer side of the composite material sheet 700 in the form of a fabric This is a step of preventing the separation of the outermost warp yarns and the outermost weft yarns while minimizing the weaving interval of the composite material sheet in the form of fabric.

As shown in detail in FIG. 12 , the outermost inclined by the separation prevention roller 710 which is provided on both sides of the outermost inclined tape 200 and is inclined at a predetermined angle with respect to the moving direction of the inclined tape 200 . The tape 200 is collected and adhered to the inside of the composite material sheet 700 in the form of a fabric.

At this time, the separation prevention roller 710 may further include any one selected from a plurality of protruding members provided to protrude from the surface of the roller or a pad-shaped friction force increasing member provided on the surface of the roller.

The melting step is performed with the warp tape 200 and the warp tape 200 by the heater 800 disposed above and below the composite material sheet 700 in the fabric form along the moving direction of the composite material sheet 700 in the form of fabric to which the outermost tape is adhered. It is a step of melting the weft tape 600 to a mutually adhesive temperature, and the pressure cooling step is pressing the composite material sheet 700 in the form of a molten fabric in the form of a molten state by a cooling roller 900 disposed on one side of the heater 800 . It is a step for temporary welding by cooling.

Finally, the step of winding the fabric (S4) is a step of fixing the shape of the fabric (S3b) and finally winding the fabric formed in the step (S3) of forming the fabric, and is a winding winder (1000). It is a step in which the entire manufacturing process is finished while the composite material sheet 700 in the form of a fabric is wound.
