Description

  TECHNICAL FIELD The present invention relates to a cutting / separating device and an apparatus for manufacturing a fiber-reinforced resin molded body, and more specifically, a cutting / separating device for cutting and separating a kneaded product of fibers and resin, and a fiber-reinforced resin for the kneaded product. The present invention relates to an apparatus for manufacturing a molded body.

  The fiber-reinforced resin molded body is produced, for example, by producing a kneaded product of fibers and resin with a kneading device, cutting the kneaded product with a cutting device, and molding the kneaded product cut with the molding device. The cutting device is disclosed in, for example, Japanese Patent Application Laid-Open No. 2016-112737 (Patent Document 1). Specifically, Patent Document 1 discloses a cutting device that causes the cutting blade to swing without moving the blade moving mechanism in size and moves the cutting blade at a high speed.

  Further, as an apparatus for cutting not a fiber reinforced resin molded product but a kneaded product such as clay, soap, kamaboko, or a soft solid material such as tofu, sake lees, konjac, etc., for example, described in JP-A-60-148421 (Patent Document 2). The technology is known. As shown in FIG. 4, the apparatus of Patent Document 2 includes an upstream and downstream belt conveyor, a cutter disposed between the belt conveyors, and an upstream side and a downstream side of the cutting slide shaft. And a plurality of pressing rollers facing the belt conveyor. And while pressing the long soft solid material flowing through these belt conveyors from above with both the upstream pressing roller and the downstream pressing roller, the piano wire of the cutter is moved up and down, It cuts a soft solid material.

  However, the conventional cutting apparatus causes problems as described below. That is, depending on the type of resin, there is a problem that the fiber reinforced resin adheres to the cutting blade of Patent Document 1 because it is tacky in a soft state that has not yet been cured. In particular, the smaller the cut fiber reinforced resin and the larger the cut surface, the easier the fiber reinforced resin adheres to the cut blade. If it does so, resin will not move forward and it will interfere with the production line.

  In addition, the piano wire of Patent Document 2 can only cut a relatively soft material, and has a problem of durability. Moreover, the fiber contained in the resin could not be cut. In addition, since a plurality of pressing rollers facing the belt conveyor are arranged on the upstream side and the downstream side of the piano wire, there is a problem that adhesive resin adheres to the belt conveyor and the pressing roller. If it does so, resin will not move orderly forward, and it will interfere with a production line.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the problem that the fiber reinforced resin after cutting adheres to the cutting blade when cutting a long uncured fiber reinforced resin with the cutting blade.

  For this purpose, the cutting / separating device according to the present invention is a cutting / separating device which is arranged in a discharge part of a kneading device for producing a kneaded product of fibers and resin and forcing the kneaded product forward, A cutting blade that moves forward and backward and cuts the front end region of the kneaded material pushed out from the discharge portion at the lower position to form a cut kneaded material and leaves the kneaded material at the upper position, and above the cutting kneaded material and ahead of the cutting blade And a return portion that comes into line contact with the cutting kneaded material that is attached to the cutting blade that returns to the upper position from the lower position, and drops the cutting kneaded material from the cutting blade that is being returned.

Thus, the roller is allowed to freely rotate, and the cut and kneaded material can be easily removed from the roller by its own weight. As another embodiment, a tube having a polygonal section having a downward ridge angle may be included instead of the roller. As another embodiment, the roller or the cylinder may be fixed to the bracket so as not to rotate. In any case, the return portion only needs to have a curved surface that bulges downward toward the cut and kneaded material. An example of such a return portion is a rod-like body having a semicircular cross section that extends in the width direction of the cut kneaded material.

  As a preferred embodiment of the present invention, the bracket is adjustable in the vertical position of the pivot. According to such an embodiment, the roller is held so as to secure an appropriate vertical gap between the roller and the kneaded material according to the vertical dimension of the kneaded material extruded from the discharge unit, The vertical position of the roller may be fixed.

  As a further preferred embodiment of the present invention, the cutting / separating device has a fluorine coating for covering the surface of the cutting blade. According to this embodiment, the kneaded material and the cut kneaded material are less likely to adhere to the cutting blade, and even if attached, they are easily removed.

According to this embodiment, the kneaded material and the cut kneaded material can be promptly conveyed forward without being deformed. As other embodiments, it may have conveying means other than the conveyor, for example, a free roller, an inclined surface such as a slide, and the like.

  The return portion may be installed only in front of the cutting blade, but is preferably disposed above the kneaded material and behind the cutting blade, and is attached to the cutting blade that returns from the lower position to the upper position. It is preferable to further include a second return portion that makes line contact with the kneaded product to be peeled off and peels off the kneaded product from the cutting blade that is being restored. According to this embodiment, the inconvenience that the kneaded material adheres to the cutting blade can be solved, and the kneaded material can be conveyed forward in an orderly manner.

In the present embodiment, The biaxial kneader includes two kneading shafts 11 arranged in parallel to each other. The rotation directions of the two rotating shafts 11b may be the same or different.

  A cylinder 12 is provided to accommodate the two kneading shafts 11 therein. A gap between the cylinder 12 and the kneading shaft 11 becomes a flow path through which the thermoplastic resin and / or fiber passes. The cylinder 12 includes a resin supply port 12a for introducing the thermoplastic resin supplied from the second kneading machine 20 into the first kneading machine 10, and a plurality of continuous fibers supplied from the fiber supply unit 30. 1 has a fiber supply port 12b for introduction into the kneader 10. The fiber supply port 12b may be provided with a member for cutting continuous fibers to be introduced. However, in the present embodiment, such a member is omitted and is introduced from the fiber supply unit 30. The continuous fiber is fed into the first kneader 10 as it is.

  A drive unit 13a is connected to one (upstream side) shaft end of the kneading shaft 11 via a speed reducer 13b that distributes torque to the kneading shaft 11. The speed reducer 13b rotates the two kneading shafts 11 in synchronization with each other at a predetermined rotational speed.

  A weir body 14 is connected to the other end (downstream side) of the kneading shaft 11. The weir body 14 can be used both as a breaker plate and an intermediate bearing, and is disposed so as to extend in a direction intersecting with the flow path, and therefore applies a back pressure to the kneaded material of the thermoplastic resin and the fiber.

<Cutting and separating device>
As shown in FIG. 1, the cutting / separating device 100 is arranged so as to face the discharge portion 15 a of the kneading device 2 that pushes the kneaded material forward. The cutting / separating device 100 is for changing the continuous kneaded material K1 pushed out from the discharge section 15a of the kneading device 2 into a discontinuous cutting kneaded material K2 to be put into the forming die 50 of the forming device 4. The cutting / separating device 100 of the present embodiment will be described mainly with reference to FIGS.

  The cutting / separating device 100 includes a cutting unit 110, a gripping unit 120, a transfer unit 130, a conveyor 140, and a return unit 150.

  The cutting unit 110 cuts the front end region of the kneaded material K1 extruded from the discharge unit 15a to generate a cut kneaded material K2. Since the cut and kneaded material K2 is put into a mold 50 of the molding apparatus 4 described later, it is cut into a size and weight suitable for the cavity of the mold 50. The cutting unit 110 includes a cutting blade 111 that cuts the kneaded material, and a control unit 112 that drives and controls the cutting operation of the cutting blade 111.

  The cutting blade 111 cuts the long kneaded material K1 that is pushed out from the discharge portion 15a and moves forward. The cutting blade 111 is disposed above the kneaded material K1 extruded from the discharge portion 15a, and is located at a lower position (FIG. 3) from the upper position (FIG. 2) above the kneaded material K1 to the same height as the kneaded material K1. The kneaded material K1 is cut by moving forward (down). Moreover, it retracts (rises) from the lower position (FIG. 3) to the upper position (FIG. 2) and returns to the upper position (FIG. 2) to prepare for the next cutting.

  The cutting blade 111 has a plate-like shape such as a kitchen knife, and has a blade 111c having a constant thickness up to the downstream front surface 111f and the upstream rear surface 111b, and a blade tip 111d that is pointed downward from the blade 111c. The front surface 111f and the rear surface 111b are flat surfaces substantially parallel to the advancing / retreating direction of the cutting blade 111. The blade edge portion 111d extending in the left-right direction so as to be orthogonal to the upstream / downstream direction is preferably inclined so that one is higher than the other and the other is lower. Thereby, the blade edge | tip part 111d penetrates into the kneaded material K1 easily.

  The blade edge portion 111d is a single blade provided at the lower edge of the cutting blade 111, and the rear surface 111b of the blade edge portion 111d is a flat surface common to the blade 111c and the blade edge portion 111d. The blade surface 111g of the blade edge portion 111d is directed forward and inclined with respect to the advancing / retreating direction of the cutting blade 111. FIG. 9 is an enlarged view showing the cutting edge portion 111 d of the cutting blade 111. The blade angle 111 of the blade surface 111g with respect to the horizontal plane is a predetermined value included in the range of 10 ° to 35 °. When the blade angle θ is less than 10 °, the kneaded material K1 is difficult to cut. When the blade angle θ exceeds 35 °, the durability of the blade edge portion 111d is deteriorated. The rear surface 111b on the upstream side of the cutting blade 111 is subjected to a surface treatment so as to prevent thermal fusion of the kneaded material K1. Further, it is preferable that the front surface 111f and the blade surface 111g on the downstream side are surface-treated. This surface treatment is, for example, a fluorine coating.

  The control unit 112 shown in FIG. 2 controls the forward / backward movement of the cutting blade 111. The control unit 112 moves the cutting blade 111 so as to be orthogonal to the kneaded material K1 pushed forward. Or you may move the cutting blade 111 so that it may incline with respect to the extrusion direction of the kneaded material K1 as a modification which is not illustrated. In order to assist such advancement and retraction of the cutting blade 111, a spring or the like may be used. The control unit 112 is, for example, a servo motor control device.

  Further, when the fiber length in the kneaded material K1 to be cut is shortened by the kneading device 2, the cutting blade 111 advances and retreats a plurality of times at the same position of the kneaded material K1 before cutting in order to increase the certainty of cutting. You may control so that it may be moved (multiple cut action). In order to realize such multiple cuttings at the same position of the kneaded material K1, for example, the first conveyor 141 is stopped. Such multi-cut action is preferably a double-cut action from the viewpoint of efficiency. The cutting unit 110 may be provided with a member (not shown) that holds the cutting blade 111. In addition, a receiving plate (not shown) for supporting the cutting blade 111 below may be provided.

  The return part 150 is arranged adjacent to the front of the cutting blade 111. There is a gap between the return portion 150 and the cutting blade 111. Further, the returning portion 150 is disposed above the cut kneaded material K2 (and the kneaded material K1) and normally does not contact the cut kneaded material K2 (and the kneaded material K1). However, when the kneaded material K1 is cut when the cut kneaded material K2 adheres to the cutting blade 111 and is lifted, the returning portion 150 comes into line contact with the cut kneaded material K2, and drops the cut kneaded material K2 downward to the original position. return.

  The return unit 150 includes a roller 151, a pivot 152, and a bracket 153. The roller 151 is a cylindrical body extending in the width direction of the kneaded material K1, that is, the direction intersecting the extrusion direction. The pivot 152 is a shaft that passes through the center hole of the roller 151. The bracket 153 is connected to both ends of the pivot 152 to support the roller 151 and the pivot 152. The bracket 153 can adjust the vertical position of the roller 151 and the pivot 152 as appropriate. Thereby, the roller 151 is adjusted and held at a vertical position corresponding to the vertical dimension of the kneaded material K1 extruded from the discharge portion 15a. The outer peripheral surface of the roller 151 is preferably surface-treated. This surface treatment is, for example, a fluorine coating.

  As a modification not shown, the roller 151 may be a cylindrical body, and both end surfaces of the cylindrical body may be rotatably supported by pivots. The roller 151 does not need to move in the vertical direction while in line contact with the cut kneaded material K2. This is because the contact area by line contact is small and the adhesive strength of the cut kneaded material K2 is small. Since the roller 151 is allowed to rotate slightly, the cut and kneaded material K2 is easily detached from the roller 151 and falls by its own weight. Further, as a modification not shown, the roller 151 may be supported so as not to rotate.

  The holding part 120 holds the kneaded material K2 at a position where the kneaded material K1 is cut by the cutting part 110 and the cut kneaded material K2 is generated. The holding part 120 holds both sides of the cut kneaded material K2. In other words, the gripping portion 120 grips both sides that intersect (in the present embodiment, orthogonal) with the moving direction of the cut kneaded material K2. In other words, the gripping part 120 pierces both side surfaces of the cut kneaded material K2 that intersect the moving direction of the gripping part 120 by the transfer part 130.

  In this Embodiment, the holding part 120 is comprised so that the cutting kneaded material K2 cut from the kneaded material K1 may be grasped from both sides. Specifically, the gripping portions 120 are respectively disposed on both outer sides of the kneaded material discharged from the discharge portion 15a, and the protruding portions 121 and the protruding portions 121 protruding inward are provided inward and outward, That is, it includes reciprocating means 122 that moves in the left-right (lateral) direction.

  The reciprocating means 122 is connected to the protrusion 121. The reciprocating means 122 moves the protrusion 121 inward in order to insert the protrusion 121 into the cut kneaded product, and also moves the protrusion 121 inserted in the cut kneaded material outward to remove the protrusion 121 from the cut kneaded product. remove. The reciprocating means 122 is not particularly limited, and the power source is not particularly limited, and examples thereof include air, hydraulic pressure, and electricity.

  The pair of protrusions 121 have fork-like or sword-like thin and sharp needle-like protrusions facing each other, and are simultaneously advanced and retracted so as to approach and separate from each other by the reciprocating means 122. When the pair of protrusions 121 are moved inward (in the direction of the arrow shown in FIG. 7), they are inserted into the kneaded material. The protrusion 121 is surface-treated so as to prevent thermal fusion of the kneaded material K2. This surface treatment is, for example, a fluorine coating.

  The transfer part (guide) 130 moves the grip part 120 toward the front to separate the kneaded material K2 after cutting from the kneaded material K1 before cutting. The transfer part 130 includes reciprocating means 133 that moves the grip part 120 in the front-rear direction. That is, the grip part 120 is configured to be able to reciprocate in the front-rear direction by the transfer part 130. In FIG. 6, the transfer unit 130 moves the grip unit 120 so that the grip unit 120 reciprocates between the second conveyor 142 and the third conveyor 143.

  Specifically, as shown in FIGS. 7 and 8, a connecting member 131 is connected to the reciprocating means 122 of the grip portion 120. A fixing member 132 is connected on the connecting member 131. A reciprocating means 133 for moving the fixing member 132 in the front-rear direction is attached to the rear of the fixing member 132. The reciprocating means 133 reciprocates in the front-rear direction a unit including the grip part 120 having the protrusion 121 and the reciprocating means 122, the connecting member 131, and the fixing member 132. The reciprocating means 133 is not particularly limited, and its power source is not particularly limited, and examples thereof include air, hydraulic pressure, and electricity.

  Note that a linear guide or the like may be used for the movement of the grip part 120 in the left-right direction and the movement of the transfer part 130 in the front-rear direction.

  As shown in FIG. 2, the conveyor 140 supports the kneaded material K1 before cutting from below and moves it forward. The conveyor 140 is a machine that continuously conveys the kneaded material, and in this embodiment, a belt conveyor that rotates a belt in a ring shape on a carriage and places the kneaded material on the belt is moved. ing.

  The conveyor 140 of the present embodiment includes a first conveyor 141, a second conveyor 142, and a third conveyor 143. The first conveyor 141, the second conveyor 142, and the third conveyor 143 are arranged in this order from the upstream side (rear) to the downstream side (front).

  The 1st conveyor 141 is arrange | positioned between the discharge part 15a and the cutting part 110 (cutting blade 111), supports the discharged kneaded material K1 from the downward direction, and moves it toward the cutting part 110 ahead. The placement surface (upper surface) of the first conveyor 141 and the lower surface of the discharged kneaded material K1 are located on the same plane. That is, the mounting surface of the first conveyor 141 is in contact with the lower surface of the kneaded material K1.

  The 2nd conveyor 142 is arrange | positioned ahead of the 1st conveyor 141, supports the cutting kneaded material hold | gripped by the holding part 120 from below, and moves it ahead. That is, the 2nd conveyor 142 moves the cutting kneaded material K2 of the position cut by the cutting part 110 ahead. The placement surface of the second conveyor 142 is located on the same plane as the placement surface of the first conveyor 141. That is, the kneaded material K1 extruded from the kneading apparatus 2 is cut on one plane. Therefore, the kneaded product K1 extruded from the kneading apparatus 2 can be prevented from expanding and contracting, and the kneaded product K1 can be cut, so that the quality of the cut kneaded product K2 can be improved.

  The 3rd conveyor 143 is arrange | positioned ahead of the 2nd conveyor 142, supports the cutting kneaded material K2 which left | separated from the holding part 120 from below, and moves it ahead. The 3rd conveyor 143 is corresponded to the conveying apparatus 3 mentioned later. The placement surface of the third conveyor 143 is located on the same plane as the placement surface of the second conveyor 142. That is, the cut and kneaded material K2 is conveyed so as to go straight forward in the extrusion direction. Accordingly, the cut kneaded material K2 is prevented from expanding and contracting and is conveyed, so that the quality of the cut kneaded material K2 can be improved.

  The first to third conveyors 141 to 143 are provided with a heating unit (not shown) for heating the kneaded product so that the kneaded product is not cooled and hardened. The heating unit has a function of keeping the temperature by adding superheated steam to the kneaded material, for example, and may be a tunnel furnace, for example.

  The second conveyor 142 and the third conveyor 143 are not separated and may be one conveyor. Moreover, you may use an inclined surface like a free roller, a slide, etc. instead of each conveyor.

  Further, in the cutting / separating device 100 of the present embodiment, a bypass path (not shown) for the kneaded material K1 to be discharged may be provided in front of the discharge portion 15a. For example, the bypass path is disposed between the discharge unit 15 a and the first conveyor 141. The bypass path is used as a primary storage for the kneaded material K1 or a path for returning the kneaded material K1 to the kneading apparatus 2 when it is determined that the kneaded material K1 is defective.

  Next, the operation of the cutting / separating apparatus 100 will be described in detail.

  As shown in FIG. 2, when the long kneaded material K1 is conveyed from the rear to the front by the conveyor 140 and the front end region in front of the cutting part 110 reaches a predetermined length, the cutting blade 111 is shown in FIG. It moves from the upper position to the lower position shown in FIG. 3 and enters between the first conveyor 141 and the second conveyor 142. As a result, the blade edge portion 111d comes into contact with the upper surface of the kneaded material K1 and penetrates to cut the front end region of the kneaded material K1. The cut front end region becomes the cut kneaded material K2. The lowering speed of the cutting blade 111 is much faster than the forward speed of the kneaded material K1. Therefore, during the cutting with the cutting blade 111, the kneaded material K1 is not pressed against the rear surface 111b of the cutting blade 111.

  Next, as shown in FIG. 4, the cutting blade 111 moves backward and comes out from between the first conveyor 141 and the second conveyor 142. Since the rising speed of the cutting blade 111 is much faster than the forward speed of the kneaded material K1, the kneaded material K1 does not adhere to the rear surface 111b. However, the cutting kneaded material K2 may adhere to the front surface 111f of the cutting blade 111 and rise together with the cutting blade 111. The reason for this is that since the adhesiveness of the cut surface immediately after cutting of the cut kneaded material K2 is large, the blade surface 111g directed downstream is pressed against the cut kneaded material K2, and the blade surface 111g adheres to the cut kneaded material K2. The cutting kneaded material K2 has a large contact area with the blade surface 111g, and the cutting kneaded material K2 adheres to the blade surface 111g. Further, the cutting surface 111g of the cutting blade 111 is pressed against the cutting kneaded material K2 for a moment. This is conceivable because a part of the object K2 wraps upward and adheres to the front surface 111f.

  Then, the cut and kneaded product K2 comes into contact with the return portion 150, and the rise is restricted. On the other hand, the cutting blade 111 rises toward the upper position (FIG. 2). Thereby, the cutting kneaded material K2 is peeled off from the cutting blade 111.

  As shown in FIG. 4, the upper surface of the cut and kneaded material K <b> 2 is in line contact with the lowermost end of the roller 151 in the return portion 150. Since the contact area between the cut kneaded material K2 and the return portion 150 is small in this way, the cut kneaded material K2 is separated from the return portion 150 by its own weight and falls downward, and the mounting surface of the second conveyor 142 as shown in FIG. Return to.

<Conveyor>
As shown in FIG. 1, the conveying device 3 moves the kneaded material cut into a predetermined size by the cutting unit 110 of the cutting / separating device 100 to the molding device 4. In the present embodiment, the transport device 3 includes a third conveyor 143 of the cutting / separating device 100, a first placement portion 41, a first grip portion 42, and a slide portion 43.

  The first placement unit 41 is a table on which the cut and kneaded material K2 conveyed from the third conveyor 143 is placed. In order to hold the cut and kneaded material placed on the first placement part 41 and put it into the mold 50, a first grip part 42 is provided. The 1st holding part 42 is a robot arm, for example.

  By the first grip portion 42, the cut and kneaded material is placed on the lower die 52 of the forming die 50 placed on the slide portion 43. The slide portion 43 is configured to be movable in the horizontal direction, and moves the lower mold 52 onto the holder 44. The slide part 43 is a slide table, for example.

<Molding device>
The molding apparatus 4 press-molds the cut and kneaded product to produce a fiber-reinforced resin molded body. The molding apparatus 4 includes a holder 44, a plate 45, a second gripping portion 46, a second placement portion 47, and a molding die 50 having an upper die 51 and a lower die 52.

  The holder 44 supports the lower mold 52 in which the cut and kneaded material is arranged by the slide portion 43. The plate 45 supports the upper mold 51 of the mold 50.

  The mold 50 includes an upper mold 51 and a lower mold 52, and the cut and kneaded material is disposed in a cavity that is a hollow portion of the upper mold 51 and the lower mold 52, and the upper mold 51 and the lower mold 52 are closed. Thus, the cut and kneaded product is pressure-molded.

  In order to grip the fiber-reinforced resin molded body manufactured by the molding die 50, a second gripping portion 46 is provided. The fiber reinforced resin molded body gripped by the second gripping portion 46 is placed on the second placement portion 47. The 2nd mounting part 47 is a stand which mounts the fiber reinforced resin molding which is a finished product.

  Then, the manufacturing method of the fiber reinforced resin molding of this Embodiment is demonstrated.

  First, a resin and fiber are kneaded to produce a kneaded product. In this step, a kneaded product as a molded body material is generated by the kneading apparatus 2 shown in FIG. 1 as follows.

  A thermoplastic resin material 25 is supplied via a hopper 24 of the second kneader 20. The kneading shaft 21 is rotated at a predetermined rotational speed using the drive unit 23a and the speed reducer 23b, and the thermoplastic resin material 25 in the cylinder 22 is melted and kneaded by the kneading shaft 21.

  Also, a plurality of continuous fiber raw materials 32 are prepared. The plurality of lines is, for example, 12,000 or more, 24,000 or more, or 50,000 or more. In the present embodiment, the fiber raw material 32 is a bundle (roving) of 12,000 or more fibers, and a plurality of bundles of these fibers are prepared. A fiber raw material 32 in which a plurality of continuous fibers are wound is placed on the placement portion 31 of the fiber supply unit 30, and the tip of the fiber raw material 32 is passed through the first guide portion 31a, and the second guide portion 31b. Support.

  Next, the resin melted by the second kneader 20 and a plurality of continuous fibers prepared by the fiber supply unit 30 are introduced into the first kneader 10. In this step, the molten resin discharged from the discharge unit 22a of the second kneader 20 is introduced into the resin supply port 12a of the first kneader 10. Further, the leading ends of a plurality of fibers guided from the first guide part 31 a and the second guide part 31 b of the fiber supply part 30 are introduced into the fiber supply port 12 b of the first kneader 10.

  Next, a kneaded product is manufactured by kneading the thermoplastic resin and the fiber while cutting the fiber. Specifically, the kneading shaft 11 is rotated at a predetermined rotational speed by rotating the rotating shaft 11b using the drive unit 13a. The rotation of the screw 11a of the kneading shaft 11 (or the screw 11a and paddle in the case of including a paddle) applies pressure to the resin and the fiber moving in the flow path formed between the kneading shaft 11 and the cylinder 12, so that the fiber Kneading resin and fiber while cutting.

  As the screw 11a rotates, the mixture that has moved through the flow path between the kneading shaft 11 and the cylinder 12 is filled between the screw 11a and the weir body 14 located on the most downstream side, and the screw 11a does not rotate. Since moderate back pressure is applied, short-passed unopened fibers can be separated. The opened fiber is impregnated with resin. The kneaded material K1 passes through the opening of the weir body 14 and is discharged from the discharge portion 15a of the die 15.

  Next, the kneaded product K1 discharged from the kneading device 2 is cut by the cutting / separating device 100 to produce a cut kneaded product K2, which is separated from the kneaded product K1 before cutting. Specifically, the following steps are performed.

  As shown in FIGS. 2 to 5, the kneaded product K <b> 1 discharged forward from the kneading apparatus 2 is cut by the cutting unit 110 to generate the cut kneaded product K <b> 2. In this process, the cutting blade 111 moves forward from above the kneaded material K1 while the kneaded material K1 pushed out from the discharge part 15a of the kneading device 2 is supported by the first conveyor 141 from the lower side and moved forward. Let Thereby, the long kneaded product K1 is cut to produce a cut kneaded product K2 having an appropriate size and weight. The cut and kneaded material K2 is supported by the second conveyor 142 from below.

  The cut and kneaded material K2 is gripped by the gripping portion 120 shown in FIG. 6 at the position returned to the second conveyor 142 by the return portion 150. Specifically, in this step, the protrusion 121 is moved inward as indicated by an arrow by the reciprocating means 122 shown in FIG. 7, and the protrusion 121 is inserted into the cut kneaded material K2.

  Thereafter, the gripper 120 is moved forward by the transfer unit 130 and separated from the rear kneaded material K1. In this step, as indicated by phantom lines in FIG. 6, the gripper 120 is moved forward to the third conveyor 143 by the reciprocating means 133 of the transfer unit 130 in a state where the kneaded kneaded material K2 is gripped by the gripper 120. .

  Next, the protrusion 121 is moved outward by the reciprocating means 122 of the gripper 120, and the protrusion 121 is removed from the cut kneaded material K2. Thereby, the cut kneaded material K2 is placed on the third conveyor 143. In this state, the grip part 120 is moved backward to the second conveyor 142 by the reciprocating means 133 of the transfer part 130. Thereby, as shown by a solid line in FIG. 6, the grip portion 120 can be arranged at the return position.

  In this manner, the reciprocating means 122 repeatedly moves the protrusion 121 of the gripping part 120 in the left-right direction, and the reciprocating means 133 repeatedly moves the gripping part 120 in the front-rear direction. For this reason, the process of cut | judging and isolate | separating the kneaded material K1 discharged ahead from the kneading apparatus 2 can be implemented continuously.

  Next, as shown in FIG. 1, the cut and kneaded material is placed in the cavity of the forming die 50 of the forming device 4 using the transport device 3. Specifically, the cut and kneaded material is conveyed to the first placement unit 41 by the third conveyor 143 while maintaining a state where the cut and kneaded material is not cooled. And the 1st holding part 42 hold | grips the cutting kneaded material mounted on the 1st mounting part 41, and moves it to the lower mold | type 52 arrange | positioned on the slide part 43. FIG. The lower mold 52 on which the cut and kneaded material is arranged is positioned on the holder 44 by the slide portion 43.

  Next, the kneaded product is pressure-molded. Specifically, the upper die 51 attached to the plate 45 is moved downward, and the upper die 51 and the lower die 52 are combined and pressure-molded. By this step, a fiber reinforced resin molded product can be produced.

  The manufactured fiber-reinforced resin molded body is gripped by the second gripping portion 46 and placed on the second placement portion 47 as shown in FIG.

  By the way, the cutting and separating apparatus 100 of the present embodiment is arranged in the discharge unit 15a of the first kneading machine 10 that manufactures a kneaded product K1 of fibers and resin, and pushes the kneaded product K1 forward. The front end region of the kneaded material K1 pushed forward and backward in the vertical direction and pushed out from the discharge portion 15a at the lower position (FIG. 3) is cut to generate the cut kneaded material K2, and separated from the kneaded material K1 at the upper position (FIG. 2). Line contact is made with the cutting blade 111 and the cutting kneaded material K2 which is disposed above the cutting kneaded material K2 and in front of the cutting blade 111 and is attached to the cutting blade 111 which returns from the lower position to the upper position. 4), the cutting kneaded material K2 is peeled off from the returning cutting blade 111 and dropped (FIG. 5). Thereby, the cutting kneaded material K2 can be conveyed forward in an orderly manner, and the inconvenience that the cutting kneaded material K2 adheres to the cutting blade 111 can be solved.

  Further, the return portion 150 of this embodiment includes a roller 151 that abuts on the upper surface of the cut kneaded material K2, a pivot 152 that extends in the width direction of the kneaded material K1 and pivotally supports the roller 151, and a bracket 153 that supports the pivot 152. Including. Accordingly, the roller 151 is allowed to freely rotate, and the cut and kneaded material K2 can be easily detached from the roller 151 by its own weight.

  Further, the bracket 153 of this embodiment can adjust the vertical position of the pivot 152. Thereby, according to the vertical dimension of the kneaded material K1 extruded from the discharge part 15a, the roller 151 is held so as to ensure a vertical gap between the roller 151 and the upper surface of the kneaded material K1 extruded from the discharge part 15a.

  Moreover, the cutting blade 111 of this embodiment has a fluorine coating that covers the front surface 111f, the rear surface 111b, and the blade surface 111g of the cutting blade 111. As a result, the kneaded material K1 and the cut kneaded material K2 are less likely to adhere to the cutting blade 111, and even if attached, they are easily removed.

  Further, the cutting / separating device 100 of the present embodiment is disposed behind the cutting blade 111, and is disposed in front of the first conveyor 141 that supports the kneaded material K1 from below and moves it forward, and the cutting blade 111. In addition, a second conveyor 142 that supports the cut kneaded material K2 from below and moves it forward is further provided. Thereby, the kneaded material K1 and the cut kneaded material K2 can be promptly conveyed forward without being deformed.

  Note that, as a modification (not shown), the cutting / separating apparatus 100 is disposed above the kneaded material K1 and behind the cutting blade 111, and adheres to the cutting blade 111 that returns from the lower position to the upper position and rises. There may be further provided a second return portion that makes a line contact with and peels the kneaded material K1 from the returning cutting blade 111 and drops it. Thereby, the kneaded material K1 can be conveyed forward in an orderly manner, and the inconvenience that the kneaded material K1 adheres to the cutting blade 111 can be solved.

  Further, according to the cutting / separating apparatus 100 and the fiber-reinforced resin molded body manufacturing apparatus 1 of the present embodiment, the kneaded product K2 extruded from the kneading apparatus 2 by the cutting unit 110 of the cutting / separating apparatus 100 can be cut. For this reason, it is possible to generate a cut and kneaded material K2 having a size and weight corresponding to the shape to be molded by the molding die 50 of the molding apparatus 4. In this way, the kneaded material can be appropriately cut according to the mold 50, so that restrictions on the available mold 50 can be reduced.

  When the kneaded product K1 is continuously cut in the cutting / separating apparatus 100, the cut kneaded product K2 and the upstream kneaded product K1 are positioned at an interval that does not slightly contact the cut surface. However, in this embodiment, the kneaded material K2 is gripped by the gripper 120, the gripper 120 is forcibly moved forward by the transfer unit 130, and the kneaded material K2 after cutting is kneaded before cutting. Pull away from K1. Thereby, since it can prevent that the cutting kneaded material K2 contacts with the kneaded material K1 before cutting extruded from the kneading apparatus 2, the shape of the kneaded material K2 appropriately cut according to the shape to be molded can be maintained. Then, the cut and kneaded material K <b> 2 is conveyed to the molding apparatus 4 while maintaining the shape appropriately cut according to the mold 50 by the conveyance device 3.

  Therefore, the cutting / separating device 100 and the fiber-reinforced resin molded body manufacturing apparatus 1 of the present embodiment reduce the restriction on the shape of the fiber-reinforced resin molded body to be manufactured, and efficiently manufacture the fiber-reinforced resin molded body. Can do.

  Further, in the cutting / separating device 100 and the fiber reinforced resin molded product manufacturing apparatus 1 of the present embodiment, a kneaded product of fibers and resin is manufactured, and the discharge unit of the kneading device 2 that pushes the kneaded product K1 forward. 15a, a cutting unit 110 that cuts the kneaded product K1 extruded from the discharge unit 15a to generate a cut kneaded product K2, a gripping unit 120 that grips the cut kneaded product K2, and the gripping unit 120. The holding part 120 holds the both sides of the cut kneaded material K2.

  The kneading apparatus 2 of the present embodiment can adjust the fiber length in the kneaded material according to the required physical properties. The kneaded material K1 discharged from the discharge portion 15a of the die 15 of such a kneading apparatus 2 is not necessarily discharged straight forward and is discharged with a shift to either the left or right with respect to the conveyance direction. Sometimes. Further, in the cutting at the cutting part 110, the cutting blade 111 may be pulled when it is slanted and may be displaced from the center. In these cases, there is a possibility that the position where the kneaded material is put into the molding die 50 of the molding apparatus 4 is shifted. However, in the present embodiment, even when the kneaded product K1 is bent from the kneading device 2 or when the molded product is pulled from the center when the cutting blade descends obliquely, the gripper is gripped. The part 120 can be gripped from both sides in order to position the cut and kneaded material K2 at the center. That is, since the holding part 120 has a centering function of the cut kneaded material K2, the positional accuracy can be improved in the movement of the held cut kneaded material K2. Thereby, the kneaded material K2 that has been cut can be appropriately arranged in the mold 50 of the molding apparatus 4. Since the flow behavior of the kneaded material in the mold 50 is closely related to the position at which the cut kneaded material is charged, a stable quality fiber-reinforced resin molded product can be produced.

  In the cutting and separating apparatus 100 and the fiber reinforced resin molded body manufacturing apparatus 1 according to the present embodiment, when the gripping part 120 grips both sides of the cut kneaded material K2, the gripping part 120 is cut by the cutting part 110. It is not necessary to hold the cut and kneaded material K2 at the position where it is formed. That is, the gripper 120 may grip the cut and kneaded material K2 at a position where there is no problem until positioning in the subsequent process.

  Further, when the gripping part 120 grips both sides of the cut kneaded product K2, the transfer unit 130 does not have to move the gripping part 120 forward to separate the cut kneaded product K2 from the kneaded product K1 before cutting. Good.

  However, in the cutting / separating apparatus and the apparatus for manufacturing a fiber reinforced resin molded body, the grip portion 120 grips both sides of the cut kneaded material K2, and the transfer portion 130 moves the grip portion 120 forward to cut the cut kneaded material K2. It is preferable to separate from the previous kneaded material K1. In this case, even if the cut kneaded material K2 is displaced from a predetermined position, for example, when the cut kneaded material K2 is shifted from the center, the gripper 120 can easily grip the cut kneaded material K2, so that the gripped kneaded material K2 is moved forward with high positional accuracy. Move to the center. In addition, it is more preferable that the gripping part 120 grips the cut kneaded material K2 at the position cut by the cutting part 110. In this case, the long kneaded material K1 can be continuously cut to efficiently produce the cut kneaded material K2. Therefore, the kneaded material K2 that has been cut can be disposed more appropriately and efficiently in the molding die 50 of the molding apparatus 4.

  Preferably, the cutting / separating apparatus 100 and the fiber-reinforced resin molded body manufacturing apparatus 1 of the present embodiment further include a conveyor 140 that supports the kneaded material K1 before cutting and moves it forward.

  Since the kneaded product K1 is pushed out from the kneading apparatus 2 at a predetermined speed, the present inventor considered that a free roller having no power is disposed immediately after discharge to use the pushing force of the kneaded product K1. . However, as a result of intensive studies, the present inventor has found that the cutting kneaded material K2 can be generated more efficiently when the conveyor 140 having a high conveying capacity is arranged instead of the free roller. That is, it was found that the kneaded material K1 extruded from the kneading apparatus 2 can be efficiently cut by moving it at a predetermined speed on the conveyor 140. In addition, by synchronizing the discharge speed of the kneaded material K1 extruded from the kneading apparatus 2 and the conveying speed of the first conveyor 141 (with the same speed), expansion and contraction of the extruded kneaded material K1 is prevented. The quality of the fiber reinforced resin molding to be manufactured can be improved.

  Preferably, in the cutting / separating device 100 and the fiber reinforced resin molded body manufacturing device 1 of the present embodiment, the conveyor 140 is disposed between the discharge portion 15a and the cutting portion 110, and the discharged kneaded material K1 is discharged. A first conveyor (first conveyor 141 in FIG. 2) that is supported from below and moved forward, and the cut and kneaded material K2 that is disposed in front of the first conveyor and that is gripped by the gripping portion 120 is downward. And a second conveyor (in FIG. 2, the second and third conveyors 142 and 143) that are supported and moved forward.

  The kneaded product K1 extruded from the kneading apparatus 2 can be moved at a predetermined speed by the first conveyor (first conveyor 141), and the cut kneaded product K2 by the second conveyor (second and third conveyors 142, 143). Can be moved at a predetermined speed. That is, the speeds of the first conveyor 141, the second conveyor 142, and the third conveyor 143 can be the same or different. For this reason, the 1st conveyor 141 is set to the speed according to the extrusion speed of the kneaded material K1 of the kneading apparatus 2, and the 2nd conveyor 142 and the 3rd conveyor 143 may be set to the speed according to the operation pitch of the downstream process. it can. Therefore, since the conveyance pitch of the cutting kneaded material K2 can be set arbitrarily, it can be moved at an appropriate speed in accordance with the shape to be molded and the like, so that a fiber-reinforced resin molded body can be manufactured more efficiently.

  In the cutting and separating apparatus 100 and the fiber reinforced resin molded body manufacturing apparatus 1 according to the present embodiment, preferably, the transfer unit 130 includes a reciprocating means 133 that moves the gripping unit 120 in the front-rear direction.

  Thereby, the holding part 120 reciprocates between the position where the kneaded material is cut and the position away from the cutting position. For this reason, the kneaded material K1 extruded from the kneading apparatus 2 can be continuously cut while preventing the cut kneaded material K2 from adhering to the kneaded material K1 before cutting. Therefore, since the cut kneaded material K2 can be manufactured more efficiently, the fiber-reinforced resin molded body can be manufactured more efficiently.

  In the apparatus 1 for manufacturing a fiber-reinforced resin molded body according to the present embodiment, the cutting / separating device 100 includes a transport device 3 (a third conveyor 143).

  Accordingly, the kneaded material K2 cut by the cutting unit 110 of the cutting / separating device 100 can be held by the holding unit 120 and moved to the third conveyor 143 by the transfer unit 130. For this reason, a fiber reinforced resin molding can be manufactured more efficiently.
