The prepreg sheet is formed by impregnating a reinforcing fiber such as carbon fiber or glass fiber with a thermoplastic resin or a thermosetting resin as a matrix resin to a thickness of about 50 to 300 占 퐉 and orienting the reinforcing fiber so as to be aligned in a predetermined direction. On the other hand, in the present embodiment, a thermoplastic resin is used as the matrix resin. Further, in the present embodiment, such a prepreg sheet is superimposed (laminated) on four layers (four pieces) to form a work W. That is, in the work W, the prepreg sheet is superimposed on the four layers in the previous step, and the work W is integrated by being caulked.

At this time, the work W is, for example, a prepreg sheet in which the orientation direction of the reinforcing fibers is 0 °, a prepreg sheet of + 45 °, a prepreg sheet of 0 °, and a prepreg sheet of -45 ° , And a pseudo isotropic sheet. However, a prepreg sheet of + 30 ° or + 60 ° may be used instead of the prepreg sheet of +45 °, and a prepreg sheet of -30 ° or -60 ° may be used instead of the prepreg sheet of -45 ° . In this case, the symbol '+' such as '+ 45 °' indicates that the orientation direction of the reinforcing fibers is shifted in the counterclockwise direction, '-' in the symbol '-45 °' .

The automatic conveyor 2 is formed in a rectangular shape when viewed in plan view and has a conveyor for automatically conveying the work W. In the present embodiment, since the work W is placed on the movable punching die 6 and conveyed together with the punching die 6, the automatic conveying machine 2 is configured to automatically convey the punching die 6.

The punching blade 9 has a frame shape corresponding to the shape of the prepreg piece P to be cut (cut) from the work W, that is, the outer shape of the prepreg piece P, (Upper end) has a pointed blade. In this embodiment, a plurality of punching blades 9 (six in FIG. 2) are provided in the punching die 6. These punching blades 9 correspond to the shape (contour) of the prepreg piece P. Therefore, although the shapes of the punching blades 9 are different from each other, a part of the punching blades 9 may have the same shape.

The work W is placed on the punching blade 9 and set on the punching die 6. In the present invention, the term 'punching edge 9' refers to the 'edge of the punching edge 9' and does not mean only 'up' in the vertical direction. Therefore, even if the punching die 6 is arranged on the work W so that the punching blade 9 faces downward in the vertical direction, for example, from the position of the work W to the tip of the sword of the punching blade 9 , And this shape is also included in the 'punching blade 9' in the present invention.

The lid 10 is detachably attached to the punching die 6 as indicated by the two-dot chain line in Fig. The lid 10 is attached to the punching frame 6 by a not-shown detachment device and is also removed from the punching frame 6. [

In the present embodiment, the desorption apparatus is formed by an adsorption apparatus having a plurality of adsorption pads for performing adsorption and desorption by ON / OFF of vacuum adsorption. The detachment device is disposed at both the first position R1 and the third position R3 of the automatic conveyor 2 shown in Fig. The detaching device disposed at the first position R1 is configured to adsorb and store the lid 10 when the work W is set in the punching die 6 to open the punching die 6, (10) is attached to the punching die (6). The desorption device disposed at the third position R3 sucks and holds the lid 10 from the punching die 6 after passing through the roller press 7 to open the punching die 6 and press the prepreg piece P, The lid 10 is attached.

The punching machine 3 has a roller press 7 and a punching die 6 in the present embodiment. The roller press 7 has a pair of rollers 7a arranged vertically as shown in Fig. 3A, and a drive motor 7b for rotating these rollers 7a. The pair of rollers 7a are arranged so as to be rotatable and opposed to each other at a predetermined interval corresponding to the thickness of the punching frame 6 (including the lid 10) The punching die 6 is pushed by passing through the punching die 6 conveyed by the punching die 6.

Therefore, the punching machine 3 having the roller press 7 and the punching frame 6 is capable of punching the punching frame 6 or the lid 10 between the pair of rollers 7a of the roller press 7, The workpiece W in the frame 6 is pressed against the punching blade 9 and the prepreg piece P is punched out of the workpiece W by the punching blade 9.

On the other hand, in the present embodiment, the punching die 6 and the lid 10 are opened by passing the punching die 6 between the pair of rollers 7a so that both the work W and the punching blade 9 So that both the work W and the punching blade 9 are pressed against each other. That is, both of the pair of rollers 7a (both of 7a 'and 7a' in Fig. 3A) are configured to be movable up and down with respect to the punching die 6. As the roller press 7, One of the pair of rollers 7a in Fig. 3A may be pressed against one of the pair of rollers 7a without pressing the work W and the punching blades 9 against each other. ) Can be moved up and down with respect to the punching die 6 and the other (lower roller 7a ") can be fixed with respect to the punching die 6. Alternatively, only one of the pair of rollers 7a in Fig. 3A (for example, the lower roller 7a ") can move up and down relative to the punching frame 6 and the other (upper roller 7a ' Even if both the workpiece W and the punching blade 9 are pressed, only one of them may be pressed.

3A, instead of moving the punching die 6 in the direction of the arrow D1 and passing the punching die 6 between the pair of rollers 7a of the roller press 7, 7 are moved toward the punching die 6 in the direction of the arrow D2 or both the roller press 7 and the punching die 6 are moved toward each other in the direction of the arrow D1 and the direction of the arrow D2 , And the punching die 6 may be passed between the pair of rollers 7a of the roller press 7.

As shown in Fig. 1, the laminator 4 includes a pickup device 11 and a temporary fixed lamination device 13 having a welder 12. The pickup device 11 includes a gripping hand 14 having a gripper such as a suction pad and a moving device 15 for moving the gripping hand 14. The moving device 15 moves the gripping hand 14 between the third position R3 of the automatic carrier 2 and the temporary fixed lamination device 13 disposed on the side of the third position R3 A first moving rail 15a and a pair of second moving rails 15b for moving the first moving rail 15a holding the gripping hand 14 in parallel with the running path 2a of the automatic carrier 2 ).

The first moving rail 15a is provided with a driving device (not shown) for moving the gripping hand 14 and the pair of second moving rails 15b is provided with a driving device 15a for moving the first moving rail 15a. (Not shown). With this configuration, the moving device 15 moves the gripping hand 14 in parallel with the running path 2a of the automatic conveyor 2, and moves the third position R3 and the temporary fixed stacking device 13).

The gripping hand 14 is provided with a plurality of gripping machines which are suction pads for performing suction and release by turning ON / OFF the vacuum suction, and these punching machines 6 carry these gripping machines at the third position R3, The prepreg piece P is held. Then, the moving device 15 moves onto the temporary fixed lamination device 13 to release the prepreg piece P gripped on the temporary fixed lamination device 13 and place it on a predetermined position. At this time, since the plurality of prepreg pieces P are formed by the plurality of punching blades 9 in the punching die 6, the prepreg pieces P are held by each gripper one by one, And is moved and placed on the temporary fixed lamination device 13 in this order.

That is, the pick-up device 11 is provided with a control section (not shown) to determine at which position in the punching die 6 the prepreg piece P is arranged and in what order to stack the prepreg pieces P in advance . Therefore, the gripping hand 14 is moved by the moving device 15 based on the input data, and the gripping tool grips the prepreg piece P, respectively. The gripping hand 14 is moved by the moving device 15 onto the provisional fixed lamination device 13 and the prepreg pieces P ). That is, the prepreg piece P that is raised after the second is stacked (overlapped) on the prepreg piece P placed before. With this arrangement, the stacker 4 stacks the prepreg pieces P in a predetermined order.

On the other hand, the number of grippers provided in the gripping hand 14 is not particularly limited, and any number can be provided. For example, when the number of the prepreg pieces P in the punching die 6 is equal to or greater than the number of the prepreg pieces P in the punching die 6, the prepreg pieces P are gripped one by one by each gripper, And the prepreg pieces P are sequentially placed (laminated) after being moved onto the temporary fixed lamination device 13. Then, as shown in Fig.

When only the number of the prepreg pieces P in the punching die 6 is reduced, all of the prepreg pieces P are sequentially placed (laminated) by reciprocating the gripping hand 14 several times.

The temporary fixed lamination device 13 includes a table 16 for placing the prepreg piece P and two welders 12. On the table 16, the prepreg piece P is raised (laminated) by the gripping hand 14. In this embodiment, an ultrasonic welding machine is used as the welding machine 12, and the ultrasonic welding machine is arranged movably within a predetermined range by the moving mechanism 17. [ A cylinder guide (not shown) is provided on the support of the table 16. A cylinder of the cylinder guide is provided with a comb plate-shaped pick plate for pressing the stacked workpiece W when melted by the welder 12. With this configuration, unnecessary parts (hardening) of the laminated prepreg pieces P can be pressed and temporarily fixed (welded) in a flat state.

The ultrasonic welder (welder 12) has a pressing member (not shown), which presses the pressing member against the workpiece and ultrasonically vibrates the pressing member to melt the thermoplastic resin as the matrix resin and then cool and solidify, The piece P is temporarily fixed by welding.

On the other hand, in the present embodiment, every time the prepreg piece P is newly stacked by the gripping hand 14 with respect to the prepreg piece P that has been stacked first, the prepreg piece P, which is newly stacked by the welder 12, The piece P is temporarily fixed by welding it to the prepreg piece P which is raised first.

The stack conveying and placing machine 5 includes a conveying and attaching machine body 18 for moving a stack of the prepreg pieces P stacked and temporarily fixed by the stacking machine 4 from the table 16, And a moving rail 19 for moving the conveying and mounting machine main body 18. The conveying and mounting apparatus main body 18 has two supporting bars 18a and an air cylinder (not shown) for raising and lowering the supporting bars 18a. The supporting bar 18a is mounted on the table 16 The bottom surface of the laminate of the prepreg piece P is supported and lifted by an air cylinder to raise the laminate, and then the laminate is lowered. With such a configuration, after the laminate on the table 16 is supported by the conveying and mounting machine main body 18, the conveying and mounting machine main body 18 moves along the movement rail 19 by a driving device (not shown) 20).

Next, the formation of the laminate by the prepreg cutting laminator 1 will be described.

First, the work W is prepared. The work W is prepared by stacking prepreg sheets to be transferred from the previous step of forming the work W and being disposed in the vicinity of the first position R1 in the automatic conveyor 2. [ Thus, the work W thus prepared is placed in a punching die 6 disposed on the first position R1 by a robot arm (not shown).

The punching die 6 disposed on the first position R1 is moved to the first position R1 by the automatic conveyer 2 so that the lid 10 is removed by the detachment device, Lt; / RTI > Therefore, the work W can be directly placed on the punching blade 9 in the punching die 6. On the other hand, it is also possible to arrange the workpiece W in the punching frame 6 manually, not by the robot arm.

When the work W is placed in the punching die 6, the lid 10 stored in the desorption apparatus is again attached to the punching die 6. After the attachment, as shown by the arrow B in Fig. 1, the punching die 6 is moved from the first position R1 to the second position R2 where the roller press 7 is arranged by the automatic conveyor 2 . The punching die 6 is moved to the upper and lower rollers 7a and 7a of the roller press 7 as shown by the arrow D1 in Figure 3a by moving the punching die 6 to the third position R3 again. ).

Then the lid 10 and the punching die 6 are pressed against the rollers 7a so that the lid 10 and the punching die 6 are opened so that the work W and the punching blade 9 are moved in mutual directions So that the workpiece W is punched into the shape of the punching blade 9, that is, the prepreg piece P having a desired shape shown by the two-dot chain line in Fig.

The punching die 6 is once stopped by passing the punching die 6 through the roller press 7 and conveying the punching die 6 to the third position R3 as indicated by the two-dot chain line in Fig. 1, (10) is removed again.

When the lid 10 is thus removed, the pick-up device 11 of the laminator 4 is operated and the prepreg piece P in the punching frame 6 is gripped by the gripping hand 14. Then, the gripping hand 14 is moved by the moving device 15, and the gripped prepreg pieces P are placed on the table 16 of the temporary fixed lamination device 13 in a predetermined order ).

After the first prepreg piece P is laid, the second prepreg piece P is superimposed (laminated) on the second prepreg piece P, and the previously set portions are welded and temporarily fixed by the welder 12. Subsequently, the new prepreg piece P is superimposed on the temporarily fixed laminate, and the new prepreg piece P is again welded (temporarily fixed). Hereinafter, all the prepreg pieces P are sequentially laminated, and welding (provisional fixing) is performed for each sheet.

When all of the prepreg pieces P are laminated and temporarily fixed to form a laminate having a desired shape in this way, the laminate is transferred to the temporary seating table 20 by the laminate conveyer / , To the subsequent process.

For the punching frame 6 after all the prepreg pieces P have been taken out by the gripping hand 14, the lid 10 stored in the attaching / detaching device is attached to the punching frame 6 again. After the attachment, the punching die 6 is moved to the returning path 2b by the automatic conveying machine 2 and then the first position R1 of the traveling path 2a . The punching frame 6 moved on the first position R1 is removed by the detachment device and the remaining portion of the punching of the workpiece W, that is, the punching blade 9, And the remaining punching pieces P are taken out.

When the remaining punching of the work W is taken out of the punching die 6 in this manner, the above-described steps are repeated to automatically produce the laminate of the prepreg pieces P.

On the other hand, the removal of the punching remainder of the work W from the punching die 6 is carried out by gripping the prepreg piece P by the gripping hand 14 of the pick-up device 11, The punching remainder of the workpiece W may be taken out by the gripping hand 14 after the workpiece W is placed on the table 16 (laminated).

In the above description, a single punching die 6 is circulated to the traveling path 2a and the return path 2b of the automatic conveyor 2 so that the set of work W in the traveling path 2a Punching of the prepreg pieces P and taking out of the prepreg pieces P (lamination of the prepreg pieces P) are carried out. However, a plurality of (for example, two) punching molds 6 are used, It is also possible to carry out the above-described steps sequentially by circulating to the traveling path 2a and the return path 2b of the automatic carrier 2. That is, when one of the punching molds 6 is operated in the running path 2a, the other punching mold 6 is kept waiting in the returning path 2b, Can be increased.

The prepreg cutting lamination apparatus 1 of the present embodiment forms the prepreg piece P by punching the prepreg piece P from the work W with the punching machine 3 and also forms the prepreg piece P in the laminator 4, The prepreg pieces P can be stacked. Therefore, the formation of the prepreg pieces P and the stacking of the prepreg pieces P are automated, so that the productivity of the members formed by stacking the prepreg pieces P can be improved. The punching tool 3 presses one of the punching blades 9 corresponding to the shape of the workpiece W and the prepreg piece P against the other or presses them against each other, And a roller press (7) for punching the prepreg piece (P). Therefore, not only the prepreg piece P can be automatically formed by passing the work W through the roller press 7 by the automatic conveyor 2, but also the conveyance of the formed prepreg piece P Can also be performed at the same time. Therefore, the productivity of the member made by laminating the prepreg pieces P can be further improved.

In the present embodiment, the work W is placed on the punching edge 9 of the punching die 6 and moved together with the punching die 6 toward the roller press 7, or the roller press 7 To the punching die 6 or by moving both the roller press 7 and the punching die toward each other so as to pass the work W together with the punching die 6 to the roller press 7 . Therefore, the roller press 7 is not soiled as compared with the case where the work W is directly passed through the roller press 7, so that the maintenance of the roller press 7 is facilitated and the prepreg piece P ) Is stabilized. Therefore, the productivity of the member made by laminating the prepreg pieces P can be further improved.

Since the punching die 6 is provided with a plurality of punching blades 9 corresponding to the plurality of prepreg pieces P, a plurality of prepreg pieces P can be formed by one punching, The productivity of the member made by laminating the prepreg pieces P can be improved.

Since the prepreg pieces P are laminated in a predetermined order, the laminate 4 is formed by laminating a plurality of prepreg pieces P formed by one punching in order to obtain a desired three-dimensional shape .

Further, since the work W is formed by laminating a plurality of prepreg sheets, the productivity of the members made by stacking the prepreg pieces P can be improved as compared with the case of punching the work of the single prepreg sheet have. In particular, by using a work formed of a pseudo isotropic sheet in which the orientation direction of the reinforcing fibers is adjusted in a predetermined direction among a plurality of prepreg sheets, a laminate with high strength can be efficiently produced.

Further, since the laminated prepreg pieces P are provided with the welder 12 for melting and temporarily fixing the prepreg pieces P to be laminated thereon, the position of the laminated prepreg pieces P is shifted, It is possible to exclude the possibility that it does not become. As a result, the yield of the resulting laminate can be increased, and the productivity of the member made by laminating the prepreg pieces P can be improved.

On the other hand, the present invention is not limited to the above-described embodiment, and various modifications are possible within a scope not departing from the gist of the present invention.

For example, in the temporary fixed lamination apparatus 13 of the above-described embodiment, the prepreg piece P is placed on the table 16 by the gripping hand 14, and the pre- Temporarily fixed). However, the table 16 is provided with a moving unit (not shown) for moving the prepreg piece P, and the position where the prepreg piece P is placed by the gripping hand 14 and the position where the prepreg piece P is placed by the welding machine 12 The place where the welding is performed may be divided on the table 16. [ That is, after the prepreg piece P is placed on the table 16 by the gripping hand 14, the prepreg piece P is moved to a place where welding is performed by the moving part, and thereafter, (Temporarily fixed). After the welding, the prepreg piece P temporarily fixed by the moving part is returned to its original position, and a new prepreg piece P is placed on the prepreg piece P (laminated). The desired laminate can be obtained by sequentially repeating this process.

In the above embodiment, a thermoplastic resin is used as the matrix resin, but a thermosetting resin may also be used.

In the above embodiment, the prepreg sheet is superimposed (laminated) in four layers (four layers) to form the workpiece W. However, if the workpiece W is formed of a prepreg sheet, Or two or three or five or more layers may be formed.

The number of punching blades 9 in the punching die 6 and the number of welders 12 in the laminating machine 4 can also be set arbitrarily.

In the above embodiment, the work W is disposed in the punching die 6 having the punching blade 9 and the work W is passed through the roller press 7 together with the punching die 6 (See Figs. 1 to 3A). 3B, by providing the punching blade 9 on the roller press 7, the work W can be guided to the roller press 7 in the direction of the arrow D1 without using the punching die The roller press 7 and the work W are moved toward each other in the direction of the arrow D2 or the roller press 7 and the work W are moved toward each other in the direction of the arrow D1, D2 so that the work W is directly passed to the roller press 7 and the prepreg piece P is punched from the work W by the punching blade.

In the above embodiment, the roller press 7 is used as the press mechanism. However, the present invention is not limited to this, and a press mechanism such as a punching press may be used instead of the roller press.

≪ Industrial Availability >

According to the prepreg cutting laminating apparatus of the present invention, it is possible to automate the formation of the prepreg pieces and the lamination of the prepreg pieces, and the productivity of the members made by laminating the prepreg pieces can be improved.

Further, for example, by passing a work through a press mechanism, it is possible not only to automatically form the prepreg piece but also to transfer the formed prepreg piece at the same time, so that the productivity of the member formed by laminating the prepreg piece can be improved Can be improved.
