  Embodiments will be described with reference to the drawings. FIG. 1 is a flowchart showing a method for manufacturing the substrate K shown in FIG. As shown in FIG. 1, in order to manufacture the base material K, after heating the whole plate-shaped body W which consists of the material which mixed the vegetable fiber and the thermoplastic resin (preheating process), The heat storage state is maintained (main heating step), the stored plate-like body W is preformed into a preformed body Z (preliminary molding step), and the preformed body Z is subjected to main molding onto the base material K (main molding step). Thereby, the base material K shape | molded by the predetermined shape can be obtained.

The vegetable fiber contained in the plate-like body W is a plant-derived fiber material. Such a fiber material can be collected from, for example, cotton, hemp, sisal, jute, kenaf and the like. Of these, kenaf is particularly preferred. This is because kenaf is effective for global environmental conservation because it grows quickly and absorbs a lot of CO ₂ . Also, it is possible to collect relatively long and strong fibers from kenaf bast.

  As the thermoplastic resin contained in the plate-like body W, for example, polyethylene (PE), polypropylene (PP), polylactic acid (PLA), or the like can be used. Among these, polypropylene is particularly preferable.

  In order to manufacture the plate-like body W, after making it into a mat shape by blending the material which mixed the vegetable fiber and the thermoplastic resin, the obtained mat body is shape | molded in a plate shape with a hot press. Thereby, the plate-shaped body W which has predetermined | prescribed thickness can be manufactured. Such a manufacturing method of the plate-like body W is disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2001-179716 and 2002-371455. In addition, the plate-like body W may be referred to by another name such as “fiberboard for thermoforming” or “preboard”.

  By heating the plate-like body W, the thermoplastic resin contained in the plate-like body W can be melted. For example, when the thermoplastic resin contained in the plate-like body W is polypropylene, since the melting point of polypropylene is 160 ° C. to 170 ° C., the plate-like body W is heated to a temperature higher than this (for example, 200 ° C.). Thus, the thermoplastic resin contained in the plate-like body W can be melted.

  2 and 3 are cross-sectional views of a preforming mold 10 for preforming the plate-like body W. FIG. As shown in FIG. 2, the preforming mold 10 has a pair of molds 12 and 14. Among these, one metal mold | die 12 has the shape where the center part was dented, and the other metal mold | die 14 has the shape where the center part protruded. The pair of molds 12 and 14 are arranged in the horizontal direction (left and right directions in FIGS. 2 and 3) so that the mold surfaces face each other. Then, the plate-like body W is disposed between the mold surfaces of the molds 12 and 14 in a state of being suspended in a direction perpendicular to the mold closing direction of the molds 12 and 14 (vertical direction in FIGS. 2 and 3). The As shown in FIG. 3, the pair of molds 12 and 14 constituting the preforming mold 10 is suspended in the vertical direction by moving the mold 12 toward the mold 14 and closing the mold, for example. The plate-like body W can be pressed from both the front and back sides. Thereby, the plate-like body W is shape | molded by the preforming body W1.

  4, 5, and 6 are cross-sectional views of the main mold 20 for main molding the plate-like body W. FIG. As shown in FIG. 4, the main mold 20 has a pair of molds 22 and 24. Among these, one metal mold | die 22 has a shape where the center part was dented, and the other metal mold | die 24 has the shape where the center part protruded. The pair of molds 22 and 24 are arranged in the horizontal direction (left and right direction in the figure) so that the mold surfaces 22a and 24a face each other. In FIG. 4, the position of the preform W1 disposed at the center of both mold surfaces 22a and 24a is hereinafter referred to as “set center”.

  As shown in FIG. 5, the preform W <b> 1 is arranged in advance on the mold surface 24 a side (molding center side) of the other mold 24 prior to the press work performed by both the molds 22 and 24. Next, as shown in FIG. 6, the pair of molds 22 and 24 constituting the main mold 20 are suspended in the vertical direction by moving the mold 22 toward the mold 24 and closing the mold, for example. It is possible to press the plate W in a state from both the front and back sides.

  As the main mold 20 for main molding the preform W1, a cold press mold is used. The “cold press” here means press molding performed without actively heating the mold surface of the main mold 20, but the mold surface 22a of the main mold 20 by processing heat, frictional heat or the like. 24a is heated to some extent. By pressing the heated preform W1 with the main mold 20 (cold press mold), the thermoplastic resin contained in the preform W1 is cooled and solidified. Thereby, the base material K shape | molded by the predetermined shape can be obtained (refer FIG. 6). In FIG. 6, the position of the base material K arranged at the center of both mold surfaces 22 a and 24 a is hereinafter referred to as “molding center”.

  The base material K thus obtained is lightweight and high in strength, and therefore can be used as a base material for vehicle interior materials. For example, the base material K can be used for door trims, instrument panels, seat back boards, partition boards, console boxes, pillar garnishes, quarter trims, and the like.

  As can be seen from a comparison between FIG. 2 and FIG. 4, the clearance CL <b> 1 of the pair of molds 12 and 14 constituting the preforming mold 10 is larger than the clearance CL <b> 2 of the pair of molds 22 and 24 constituting the main mold 20. Is also set larger. For example, when CL2 is 5 mm, the clearance CL1 is set to 10 mm, which is larger than that. Therefore, instead of forming the plate-like body W into the base material K at a time, first, the plate-like body W is formed into the preformed body W1, and then the preformed body W1 is formed into the base material K. Thus, it is possible to form in steps (in two steps).

  Further, the preform W1 introduced to the center of the set in the main molding step is moved to the center of the molding to perform the main molding, so that the preform W1 is placed on the mold surface while the molds 22 and 24 are being closed. It is possible to avoid being caught by a part and to restrict the central part of the base material K from being stretched by a part of the mold surface after press working to become thin.

  Next, the configuration of the hanger 30 that holds the plate-like body W will be described. FIG. 7 is a perspective view of the hanger 30 for holding the plate-like body W in a suspended state. FIG. 8 is a side view of the hanger 30.

  As shown in FIG. 7, the hanger 30 is provided with a shaft 32 made of a metal pipe-like member such as iron or aluminum. The length of the shaft 32 is formed larger than the lateral width of the plate-like body W. Two clamps 34 for sandwiching the upper edge portion of the plate-like body W are attached to the lower portion of the shaft 32. Two rollers 36 mounted on slide rails 58a and 58b, which will be described later, are attached to the upper portion of the shaft 32. A pair of attachment members 38 are provided at both ends of the shaft, and the roller 36 is attached to the upper portion of the shaft 32 via the attachment member 38. The rollers 36 are respectively attached to the front surface side and the back surface side of the attachment member 38. Accordingly, the four rollers 36 are attached to the hanger 30. In addition, the clamp 34 and the roller 36 are positioned substantially coaxially with respect to the shaft 32 in the vertical direction.

  As shown in FIG. 8, the clamp 34 has a pair of clamping members made of a metal plate member such as iron or aluminum. Both clamping members are composed of a movable plate 34a and a fixed plate 34b, and a hinge 35 is attached between the movable plate 34a and the fixed plate 34b. It is comprised so that can be pinched | interposed. That is, one of the holding members can be opened and closed between a closed position for holding the upper edge of the plate-like body W and an open position for releasing the upper edge of the plate-like body W with respect to the other. Yes. A spring member 37 is attached between the upper end portions of the movable plate 34a and the fixed plate 34b, and the lower end portion of the movable plate 34a is urged by the spring member 37 in the closing direction with the hinge 35 as a fulcrum. An anti-slip member 34c is provided on the inner surface side of the lower end portions of the movable plate 34a and the fixed plate 34b to restrict the plate-like body W from falling downward.

  Then, the whole structure of the base-material shaping | molding apparatus 100 is demonstrated. FIG. 9 is a plan view schematically showing the entire base material forming apparatus 100 for forming the base material K. FIG. FIG. 10 is a perspective view of the base material forming apparatus 100 excluding the hanger collection apparatus 70. As shown in FIG. 9, the base material forming apparatus 100 includes a heating device that heats the plate-like body W, a forming device that forms the plate-like body W into the base material K, and a hanger collection device 70. The heating device includes a preforming device (an example of a heating device) 50 and a main heating device 40. The preheating device 50 and the main heating device 40 are arranged in this order from the carry-in entrance G of the base material forming device 100.

  Further, as shown in FIG. 9, a hanger loading mechanism 80 is provided on the front side of the hanger collection device 70 (the lower side in the drawing of FIG. 9). The front side of the hanger loading mechanism 80 (the lower side in the drawing of FIG. 9) is open, and is a hanger loading port 80a into which the hanger 30 with the plate-like body W suspended can be loaded. The plate-like body W is put into the preheating device 50 from the carry-in entrance G of the base material forming apparatus 100, heated to about 170 ° C. by the preheating device 50, and further put into the main heating device 40 in a heated state. .

  The hanger collection device 70 is a device for collecting the empty hanger 30 taken out from the substrate K after the formation of the substrate K. The empty hanger 30 is conveyed to the carry-in unit 70A of the hanger collection device 70 by a transfer mechanism (not shown) and collected by the collection unit 70B. As described above, the forming process of the base material K is performed while conveying the hanger 30 according to the arrow direction in FIG. The hanger loading mechanism 80 is a mechanism for transferring the hanger 30 loaded from the hanger loading port 80a into the preheating device 50, and the configuration thereof will be described in detail later.

  The heating device 40 includes a hot-air circulating heating furnace 42 that can uniformly heat the plate-shaped body W by passing the plate-shaped body W therein, and the plate-shaped body W that is transported inside the heating furnace 42. And a transfer device 44 that can be used. The internal temperature of the heating furnace 42 is set to, for example, 200 ° C., and the thermoplastic resin contained in the plate-like body W is obtained by heating and holding the plate-like body W heated to around 170 ° C. at 200 ° C. It is possible to maintain the molten state.

  The conveying device 44 shown in FIG. 10 is configured by two chain conveyors 46a and 46b arranged in parallel, and the two chain conveyors 46a and 46b are operated in synchronization. Both ends of the shaft 32 constituting the hanger 30 are placed on the upper surfaces of the two chain conveyors 46a and 46b. Thereby, the conveying apparatus 44 can convey the plate-shaped body W hold | maintained in the state suspended by the hanger 30 in the inside of the heating furnace 42. FIG.

  Inside the heating furnace 42, a preforming die 10 for pre-forming the plate-like body W is installed. The conveying device 44 and the preforming die 10 are installed at an offset position inside the heating furnace 42. The “offset position” here means “a position where the central axes are separated from each other”. Specifically, the central axis P1 of the transport device 44 and the central axis P2 of the preforming die 10 are in the horizontal direction. This means that the position is far away.

  A main mold 20 is installed below the preforming mold 10. The preforming mold 10 and the main mold 20 are arranged at an offset position. Here, the “offset position” means “a position where the central axes are separated from each other”. Specifically, the central axis P2 of the preforming mold 10 and the central axis P3 of the main mold 20 are vertically moved. It means the position away in the direction. In addition, the substantially second half part of the heating furnace 42 is formed in a substantially L shape in a plan view, and can accommodate both the transport device 44 and the preforming die 10 arranged at the offset position. The main mold 20 is installed below the preforming mold 10 and outside the heating furnace 42.

  As shown in FIG. 10, the base material forming apparatus 100 includes a first slide rail (an example of a carry-in rail and an inner carry-in rail) 58a that can rotatably place the roller 36 attached to the hanger 30; And a second slide rail 58b. The first slide rail 58a is disposed substantially vertically and substantially horizontally in plan view with the transport device 44 on the near side of the transport device 44. The first slide rail 58a extends from the transport portion 50A of the preheating device 50 to the transport portion 40A (transport device 44) of the main heating device 40. It is extended to the front side. The second slide rail 58b is disposed substantially vertically and substantially horizontally in plan view with the conveying device 44 on the back side of the conveying device 44, and extends from the terminal portion 40B of the conveying device 44 to the preforming die 10. When the roller 36 (see FIGS. 7 and 8) of the hanger 30 is placed on the first slide rail 58a, only the two rollers 36 attached to the front side (left side in FIG. 8) of the attachment member 38 are provided. Is placed. When the roller 36 of the hanger 30 is placed on the second slide rail 58b, only the two rollers 36 attached to the back side (the right side in FIG. 8) of the attachment member 38 are placed. Since the rollers 36 mounted on the slide rails 58a and 58b are deeply fitted into the apex portions (not shown) of the slide rails 58a and 58b, the rollers 36 are hardly detached from the slide rails 58a and 58b. For this reason, the hanger 30 can be stably conveyed along the 1st slide rail 58a and the 2nd slide rail 58b even in the state in which only the two rollers 36 were mounted in this way.

  Near the first slide rail 58a and the second slide rail 58b, horizontal movement mechanisms (not shown) are respectively provided. The horizontal movement mechanism can move the hanger 30 placed on the first slide rail 58a or the second slide rail 58b in the horizontal direction. Therefore, the hanger 30 placed on the first slide rail 58a can be transferred from the carry-in portion 50A of the preheating device 50 to the carry-in portion 40A of the main heating device 40 by a horizontal movement mechanism. Furthermore, the hanger 30 placed on the second slide rail 58b can be transferred from the terminal end 40B of the transport device 44 to the preforming die 10 by a horizontal movement mechanism. The base material forming apparatus 100 also delivers a first hanger delivery mechanism (not shown) for delivering the hanger 30 from the first slide rail 58a to the transport device 44, and delivers the hanger 30 from the transport device 44 to the second slide rail 58b. And a second hanger delivery mechanism (not shown).

  Next, the configuration of the hanger throwing mechanism 80 will be described. Here, FIG. 11 is a side view when viewed from the direction of arrow A in FIG. 9, and shows a side view of the hanger throwing mechanism 80 before operating the first cylinder 74 and the second cylinder 84. FIG. 12 shows a side view of the hanger throwing mechanism 80 in a state where the first cylinder 74 is operated. FIG. 13 shows a side view of the hanger throwing mechanism 80 in a state where the first cylinder 74 and the second cylinder 84 are operated. FIG. 14 is a plan view of a portion where the tip of the connection rail 86 and the tip of the first slide rail 58a overlap in the state shown in FIG.

  As shown in FIG. 11, the hanger throwing mechanism 80 includes a wall portion 72 that is provided substantially horizontally in a side view. The wall portion 72 extends along the loading direction of the plate-like body W (left and right direction in FIG. 11), and the first cylinder 74 and the first cylinder 74 are provided on the side surface on the front side (front side in FIG. 11). A two-cylinder 84 and a guide rail (an example of a carry-in rail and an outer carry-in rail) 82 are provided. The guide rail 82 is provided at the same height as the first slide rail 58 a between the first cylinder 74 and the second cylinder 84, and extends along the carry-in rail 72.

  First, the second cylinder 84 will be described. As shown in FIG. 11, the second cylinder 84 is provided above the side surface of the wall portion 72 and extends substantially horizontally along the wall portion 72 in a cylindrical shape. A second moving portion 88 that is movable along the side surface is attached to the front side surface of the second cylinder 84. A connection rail 86 extending along the second cylinder 84 is connected to the second moving portion 88 via an L-shaped connection member 87. The connection rail 86 has the same shape as the first slide rail 58a and the second slide rail 58b, and the roller 36 attached to the hanger 30 can be rotatably mounted thereon. The connecting rail 86 is slightly shorter than the guide rail 82. A groove (not shown) is formed along the connection rail 86 on the back surface of the connection rail 86 (the surface opposite to the front surface). The groove is fitted to the guide rail 82 on the front side of the guide rail 82, and thereby the connection rail 86 is movable along the guide rail 82. That is, by operating the second cylinder 84, the second moving portion 88 moves along the side surface of the second cylinder 84, and accordingly, the connection rail 86 connected to the second moving portion 88 is located on the guide rail 82. Is configured to move. Thus, the second cylinder 84 is a so-called rodless cylinder in which the second moving portion 88 and the connection rail 86 move outside the cylinder when the cylinder is operated.

  As shown in FIG. 11, the first cylinder 74 is provided below the side surface of the wall portion 72, and extends substantially horizontally along the wall portion 72 in a cylindrical shape. A first moving portion 78 that is movable along the side surface is attached to the front side surface of the first cylinder 74. An axial hanger rod (an example of a holding device rod) 76 extends from the first moving portion 78 along the first cylinder 74 toward the preheating device 50 side. Therefore, by operating the first cylinder 74, the first moving part 78 moves along the side surface of the first cylinder 74, and the hanger rod 76 extending from the first moving part 78 moves accordingly. ing. Thus, the first cylinder 74 is also a so-called rodless cylinder in which the first moving portion 78 and the hanger rod 76 move outside the cylinder when the cylinder is operated.

  Next, the manner in which the hanger 30 from which the plate-like body W is suspended will be described in order from the hanger input port 80a of the hanger input mechanism 80 into the preheating device 50. When the hanger 30 is loaded from the hanger loading port 80a of the hanger loading mechanism 80, only the two rollers 36 attached to the back side of the mounting member 38 among the rollers 36 of the hanger 30 are on the connection rail 86. (State of FIG. 11). At this time, the front end surface 76a of the hanger rod 76 is in contact with the side surface of the attachment member 38 located on the front side (left side in FIG. 11) of the attachment member 38 of the hanger 30 as shown in FIG. It is placed so as to be in a state.

  Next, in the state of FIG. 11, the carry-in entrance G is opened, the second cylinder 84 is operated, and the second moving unit 88 is moved. Then, the connection rail 86 connected to the second moving unit 88 moves from the carry-in entrance G toward the preheating device 50 along the guide rail 82. When the second cylinder 74 is activated and the second moving part 88 is moved to the tip of the side surface of the second cylinder 84 (left end in FIG. 12), the tip of the connection rail 86 (left end in FIG. 12) is It overlaps in the horizontal direction with the tip end portion (the right end portion in FIG. 12) of the first slide rail 58a disposed in the preheating device 50. That is, the end portion of the first slide rail 58a is superimposed on the front side of the paper surface of FIG. 11 and the front end portion of the connection rail 86 is superimposed on the back side of the paper surface of FIG. 11 (see FIG. 14). Further, the leading end portion of the connection rail 86 that has moved into the preheating device 50 is heated by the preheating furnace 52 in the preheating device 50. On the other hand, the hanger 30 placed on the connection rail 86 moves to the preheating device 50 side with the movement of the connection rail 86 and is located between the hanger charging mechanism 80 and the preheating device 50. (State of FIG. 12). When the hanger 30 moves to the preheating device 50 side, the front end surface 76 a of the hanger rod 76 that is in contact with the hanger 30 is separated from the hanger 30.

  Further, in a state where the front end portion of the connection rail 86 and the front end portion of the first slide rail 58a (the right end portion in FIG. 12) are overlapped in the horizontal direction (state in FIG. 12), the connection rail 86 and the first rail are viewed in plan view. The distance between the slide rail 58a is slightly larger than the diameter of the shaft 32 of the hanger 30 (see FIG. 14). For this reason, when the connection rail 86 is overlapped with the first slide rail 5 in the horizontal direction, the roller 36 attached to the front side of the attachment member 38 among the rollers 36 of the hanger 30 is the first. It will be placed on one slide rail 58a. Accordingly, in the state shown in FIG. 12, of the two rollers 36 of the hanger 30 positioned in the preheating device 50, the roller 36 attached to the back side of the attachment member 38 is placed on the connection rail, and the attachment member 38. The roller 36 attached to the front side is placed on the first slide rail 58a.

  Next, in the state of FIG. 12, the 1st cylinder 74 is operated and the 1st moving part 78 is moved. Then, the hanger rod 76 extended from the 1st moving part 78 moves to the preheating apparatus 50 side from the carrying-in entrance G. When the hanger rod 76 moves and comes into contact with the side surface of the mounting member 38 located on the rear side (right side in FIG. 12) of the mounting member 38 of the hanger 30, the hanger rod 76 then reserves the hanger 30. It moves while being pushed out to the heating device 50 side. As a result, the hanger 30 positioned between the hanger charging mechanism 80 and the preheating device 50 is pushed into the preheating device 50 by the hanger rod 76 (the state of FIG. 13). In this state, as shown in FIG. 14, the end of the first slide rail 58a is on the front side of the page of FIG. 13, and the rear end of the connection rail 86 (the right end in FIG. 13) is the back of the page of FIG. It is in a state of being superimposed on the side. The tip of the hanger rod 76 that has moved into the preheating device 50 is heated by the preheating furnace 52 in the preheating device 50.

  Further, when the hanger 30 is put into the preheating device 50, as described above, the roller 36 attached to the back side of the attachment member 38 of the hanger 30 is separated from the connection rail, and the front of the attachment member 38 of the hanger 30 is removed. The roller 36 attached to the side is placed on the first slide rail 58a. That is, the hanger 30 is transferred from the connection rail 86 to the first slide rail 58a by putting the hanger 30 into the preheating device 50.

  By the above procedure, the hanger 30 from which the plate-like body W is suspended is thrown into the preheating device 50 from the hanger loading port 80a of the hanger loading mechanism 80. Thereafter, from the state of FIG. 13, the first cylinder 74 and the second cylinder 84 are operated, and the hanger rod 76 and the connection rail 86 are returned to the hanger input mechanism 80 side again. Then, the other hanger 30 from which the plate-like body W is suspended is placed on the connection rail 86, and the other hanger 30 is put into the preheating device 50 by the same procedure. In this way, the plurality of hangers 30 from which the plate-like body W is suspended can be thrown into the preheating device 50 from the hanger throwing mechanism 80.

  As described above, the hanger rod 76 and the connecting rail 86 move along the side surfaces of the cylinders 74 and 84 outside the cylinders 74 and 84, so that the hanger rods introduced into the preheating device 50 are used. When the distal end portion of 76 and the distal end portion of the connection rail 86 return to the hanger loading mechanism 80 side again, the hanger rod 76 and the connection rail 86 are not accommodated in the cylinders 74 and 84. For this reason, even if the tip of the hanger rod 76 and the tip of the connection rail 86 are heated in the preheating device 50, the heat accumulated in the hanger rod 76 and the connection rail 86 is transmitted to the cylinders 74 and 84. It is difficult to adversely affect the operation of the cylinders 74 and 84.

  As described above, in the base material forming apparatus 100 according to the present embodiment, the hanger rod 76 that has moved into the preheating device 50 is not accommodated in the first cylinder 74, so the hanger rod 76 is not in the first cylinder 74. It is possible to prevent heat from being affected. For this reason, it can prevent that the 1st cylinder 74 raise | generates a malfunction by heat, and generation | occurrence | production of the conveyance malfunction of the plate-like body W can be prevented thru | or suppressed.

  Further, in the base material forming apparatus 100 according to the present embodiment, the space between the guide rail 82 disposed outside the preheating device 50 and the first slide rail 58a disposed in the preheating device 50 is divided. Then, a connection rail 86 movably disposed along the guide rail 82 and a second rail 84 that is disposed outside the second cylinder 84 and moves along the extending direction of the second cylinder 84 when the second cylinder 84 operates. 2 movement part 88 and the connection member 87 which connects between the connection rail 86 and the 2nd movement part 88 are provided. For this reason, even if it does not connect between the guide rail 82 and the 1st slide rail 58a by the outer side and the inner side of the preheating apparatus 50, the 2nd moving part 88 moves, and the connection rail 86 is moved to the 1st slide rail 58a. Can be moved to the side. Furthermore, since the connection rail 86 that has moved into the preheating device 50 is not accommodated in the second cylinder 84, the connection rail 86 can be prevented from exerting a thermal effect on the second cylinder 84. . As a result, the space between the guide rail 82 and the first slide rail 58a can be physically blocked by the openable / closable entrance G, and the inside of the preheating device 50 can be warmed effectively.

The modifications of the above embodiment are listed below.
