  However, conventionally, an apparatus capable of efficiently producing the plastic ventilation member and other plastic molded articles of the above-described form from the plastic laminate as described above, in particular, integrating and cutting out the plastic laminate simultaneously. Moreover, no device capable of forming a slope has been proposed.

  Accordingly, the present invention provides a processing apparatus for a plastic laminate that has all such functions and can automatically and efficiently produce the plastic ventilation member and other plastic molded products from the plastic laminate. The task is to do.

  In the present invention, a lifting frame supported in a vertically movable manner is arranged in a rectangular parallelepiped frame, and a fusing device comprising a large number of a pair of upper and lower heating wires arranged at predetermined intervals is attached to the lower side of the lifting frame. The stacking material mounting table is installed below the fusing device, and the fusing device moves downward in the same vertical direction as the elevating frame when the elevating operation is performed together with the elevating frame. The above problem has been solved by a plastic laminate processing apparatus characterized in that the latter half of the lowering movement moves in an obliquely downward direction different from the lifting frame.

  Preferably, a lowering operation different from that of the elevating frame of the fusing device is guided by the action of a cam, and as a cam in that case, a plate cam having a vertical groove followed by a dogleg-shaped groove, Alternatively, a plate cam or the like in which a series of grooves that bend in the order of vertical, inclined, and vertical can be used. Moreover, it is preferable that the pair of heat wires of the fusing device are arranged in parallel at predetermined intervals with a pair of heat wires that are slightly shifted in the horizontal direction and are arranged in stages on the top and bottom.

  More preferably, the end portion of the hot wire is fixed via a coil spring, the laminate material holding means is installed on the laminate material mounting table, and is generated on the frame along with the fusing process. A hood for sucking and collecting suspended matter such as material waste will be installed. There may be a case where a plurality of fusing parts composed of the lifting frame, fusing device and mounting table are arranged and operated simultaneously.

  The present invention is as described above, and a laminated material obtained by laminating a plurality of plastic plates can be melted obliquely at the same time by a single descending operation of a fusing device and can be integrally processed. The plate ventilation member and other plastic molded products are effective in mass production at low cost.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of an apparatus according to the present invention, FIG. 2 is a plan view thereof, FIG. 3 is a side view thereof, and reference numeral 1 is a rectangular parallelepiped frame generally provided with casters 2 on its upper surface. 3 and its power distribution mechanism are arranged.

  The power distribution mechanism will be described. Reference numerals 4 and 5 denote gear mounting shafts that are arranged on both sides of the upper surface of the frame 1 and are supported by bearings 6, respectively. The chain 10 and the like are wound between these and the corresponding winding transmission means such as the sprocket 9 fixed to the output shaft of the drive motor 3. In addition, bevel gears 11 to 14 that rotate in the vertical direction are installed in the same direction at both ends of each gear mounting shaft 4 and 5.

  Gear shafts 15 to 18 are installed in the vertical reports at the four inner corners of the frame 1, and the upper portions and the stock companies are pivotally supported in the frame 1. The written gear tokens 15 to 18 are threaded off, and bevel gears 19 to 22 that mesh with the bevel gears 11 to 14 and rotate in the horizontal direction are fixed to the upper ends.

  Thus, the rotational driving force of the drive motor 3 is distributed from the sprocket 9 and the chain 10 to the gear mounting shafts 4 and 5 via the sprockets 7 and 8, and the rotations of the gear mounting shafts 4 and 5 are changed from the bevel gears 11 to 14 to the bevel gear 19 respectively. To 22 and the gear shafts 15 to 18 are simultaneously driven to rotate.

  Reference numeral 24 denotes an elevating frame that fits within the frame 1 and moves in the vertical direction, and includes female screw cylinders 25 into which the gear shafts 15 to 18 are screwed. Due to this screwing relationship, the lifting frame 24 moves up and down as the gear shafts 15 to 18 rotate.

  Support rods 27 and 28 are passed between the support rod mounting plates 26 on both sides of both ends of the lifting frame 24. Reference numerals 29 and 30 denote slide blocks slidably attached to the support rods 27 and 28. Brackets 31 and 32 for supporting the heat cutter 33 constituting the fusing device are suspended from the slide blocks 29 and 30, respectively. Is done.

  In the heat cutter 33, hot wire windings 36 and 37 are arranged at predetermined intervals on the electrode rods 34 and 35 installed between the brackets 31 and 31 and between the brackets 32 and 32, respectively. , 39. The end portions of the heat wires 38 and 39 are preferably fixed to a connecting member passed between the brackets 31 and 31 and between the brackets 32 and 32 via a coil spring. In the case of fixing through the coil spring as described above, the hot wires 38 and 39 are moderately tensioned, so that the fusing operation is performed smoothly and smoothly, and the hot wires 38 and 39 may be cut off due to excessive tension. Is prevented.

  The heat cutter 33 performs a lowering operation in a direction different from that of the lifting frame 24 in the latter half of the lowering operation, but in the illustrated embodiment, the movement is guided by the action of a cam. That is, a cam follower 41 is installed on the one side bracket 32, 32. The cam follower 41 is fitted in a groove 43 of a plate cam 42 protruding in the horizontal direction and installed on the frame 1, along the groove 43. A sliding protrusion 41a is arranged.

  The groove 43 is, for example, a vertical groove and a dogleg-shaped inclined groove. In the case of the plate cam 42 having the groove 43 having such a shape, a trapezoidal ventilation member having a slope on both sides as shown in FIG. 8 is formed. Further, when forming a trapezoidal ventilation member 46a whose cross-sectional shape is a slope on one side and a vertical surface on one side, a plate cam 42 is formed with a series of grooves 43 bent in the order of vertical, inclined, and vertical. Use it. It is preferable that a plurality of types of plate cams 42 having different shapes of the grooves 43 are prepared and exchangeable.

  If necessary, a pulley-like support roll 44 that rolls on the support rods 27 and 28 is provided at the upper end of the cam follower 41 (see FIG. 1).

  On the bottom of the frame 1, a mounting table for the laminated material 46 to be cut is disposed. For example, the mounting table is formed by juxtaposing a large number of receivers 47 on the base 50, and each receiver 47 is provided with a heat ray guide 48 having a triangular cross section on one side thereof. An open portion 49a is provided on the upper surface of the heat ray guide 48 (see FIG. 4).

  When fusing with the hot wires 38 and 39, the laminated material 46 on the mounting table may move. Therefore, it is preferable to provide a pressing means for pressing the laminated material 46 from above to prevent the shift movement. For example, it is conceivable to install a rough comb-like metal material on the base 50 so as to be able to undulate as a holding means. After the laminated material 46 is placed on the placing table in a state where the metallic material is raised, the metallic material is brought down on the laminated material 46, and the laminated material 46 is held down by its weight. The hot wires 38 and 39 to be described later move up and down avoiding this metal material.

  The operation of the ventilation member manufacturing apparatus having the above configuration will be described. When the driving motor 3 is started after the laminated material 46 to be cut is placed on the placing table, the gear shafts 15 to 18 are rotated as described above. Along with this, the lifting frame 24 is lowered. At that time, the heat wires 38 and 39 are heated to a temperature at which the laminated material 46 made of plastic can be melted, and the laminated material 46 is melted and melted by contacting the laminated material 46. The upper and lower plastic plates 51 are welded together on the surface, and all the laminated plastic plates 51 are integrated.

  A method of fusing with the hot wires 38 and 39 will be described with reference to FIGS. First, when the elevating frame 24 is lowered, the protrusion 41a of the cam follower 41 moves along the vertical portion of the groove 43 of the plate cam 42. However, until reaching the lower end of the vertical portion, the hot wires 38 and 39 are directly below. It moves (FIG. 4) and eventually reaches the lower end of the vertical portion, and the lower heat wire 38 contacts the upper surface of the laminated material 46 (FIG. 5).

  Therefore, when the elevating frame 24 is further lowered, the protrusion 41a moves to the inclined portion (upper half portion of the dog-shaped shape) of the groove 43, and moves in the diagonally downward left direction in FIG. 1 (FIG. 6). Thus, fusing and welding in the first inclined direction are performed by the lower heat wire 38 (melting line a in FIG. 6).

  After the first fusing, the lower heating wire 38 moves along the back side of the inclined surface of the heating wire guide 48 through the gap 49 between the heating wire guides 48 as the elevating frame 24 further descends. On the other hand, the upper heating wire 39 contacts the upper surface of the laminated material 46 (FIG. 6).

  At that time, the protrusion 41a is located at the bending point of the groove 43, and further moves downward to move diagonally downward to the right in FIG. 1 along the inclined portion of the groove 43 (the lower half of the V shape). Thus, the laminated material 46 is melted and welded by the hot wire 39 in the direction oblique to the fusing line a (see fusing line b, FIG. 7 and FIG. 8B).

  At that time, the hot wire 39 escapes into the hot wire guide 48 through the opening 49 a of the hot wire guide 48. Thus, the laminated material 46 is cut into a large number of trapezoidal ventilation members 46a (see FIG. 8C). Since a material residue or the like may be generated and float during the fusing process using the heat wires 38 and 39, a suction hood may be provided so as to cover the frame in order to suck and collect the material.

  As described above, when the plate cam 42 having the grooves 42 formed in the order of vertical, inclined, and vertical is used, the fusing line b is put in the vertical direction. Further, for example, by making a straight line portion of the U-shaped inclined groove 43 of the illustrated U-shaped inclined groove 43 into a curved line, the molten section can be recessed in a curved state. In addition, by changing the shape of the groove 42, it is possible to obtain a melted cross section having an arbitrary shape.

  In the above-described embodiment, the lowering operation different from that of the lifting frame 24 of the heat cutter 33 is achieved by the plate cam 42, but the achievement means is not limited to this, and for example, a cylinder is installed in the lifting frame 24. Thus, it is also possible to employ a method of drawing a locus in a diagonally downward direction by pressing the brackets 31 and 32 simultaneously with the lowering of the elevating frame 24.

  It can also be set as the structure which arrange | positions the fusing process part which consists of the raising / lowering frame 24 mentioned above, a fusing apparatus, and a mounting base in the two or more steps | paragraphs, and the common gear shafts 15-18. Needless to say, in that case, the production capacity is several times that of a single stage.

  Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims.
