  As shown in FIG. 31, the receiving member 14 is fixed to the table 3 by fastening means such as bolts, and can receive and discharge the material discharged from the discharging means 2 (nozzle portion 2a) on the mounting surface 14a. It is configured to be able to swing together with the table 3 by the B-axis swing means 7 and to rotate together with the table 3 by the C-axis rotating means 8. Further, a heater h is attached to the receiving member 14, and a fixing material (a solid material made of the same kind of resin material as the resin material discharged from the discharge means 2) previously mounted on the mounting surface 14a is used. It can be melted by the heat from the heater h. Thus, the material discharged from the discharge means 2 is laminated on the fixing material to form a laminate of an arbitrary shape.

  The moving means is capable of relatively moving the discharging means 2 and the table 3 in the X-axis direction. In the present embodiment, the moving means 4 for the X-axis, the moving means 5 for the Y-axis, and the moving means for the Z-axis And means 6. Among these, the X-axis moving means 4 and the Y-axis moving means 5 are attached to a frame F2 located at the upper part of the housing K, and move the discharging means 2 and a blade 11 to be described later in the X direction and the Y direction. In addition, the Z-axis moving means 6 is attached to the frame F1 located on the side of the housing K, and enables the holding means 12 to move in the Z direction.

  Specifically, as shown in FIGS. 22 and 24, the X-axis moving unit 4 includes a ball screw N1 that rotates by driving an actuator such as a motor m1 and a slide that slides along the rail L1 by rotating the ball screw N1. And a member T1. As shown in the figure, the Y-axis moving means 5 has a ball screw N2 that rotates by driving an actuator such as a motor m2, and a slide member T2 that slides along the rail L2 by rotation of the ball screw N2. It is configured.

  The rail L1 extends in the X-axis direction in the frame F2 of the housing K. The rotation of the ball screw N1 enables the slide member T1 to move in the X-axis direction along the rail L1. The slide member T1 extends in the Y-axis direction, and the slide member T2 can be moved in the Y-axis direction along the rail L2 by rotation of the ball screw N2. An attachment member B1 to which the ejection means 2 and the cutting tool 11 are attached is fixed to the slide member T2, and the ejection means 2 and the cutting tool 11 are moved in the X-axis direction by rotating the ball screw N1. By rotating and driving the ball screw N2, the discharge means 2 and the cutting tool 11 can be moved in the Y-axis direction.

  Further, as shown in FIGS. 22 and 23, the Z-axis moving means 6 is configured to be able to move the mounting member B2 up and down by a ball screw N3 rotated by driving of an actuator such as a motor m3. The holding means 12 is fixed to B2. Thus, by driving the motor m3, the holding means 12 is configured to be able to move in the vertical direction (Z direction) together with the table 3 and the receiving member 14.

  The control means 9 is composed of, for example, a microcomputer or the like having a predetermined program built therein in a control panel accommodating portion U installed at a position adjacent to the housing K, and includes moving means (X-axis moving means 4, Y-axis moving means). The means 5 and the Z-axis moving means 6), the B-axis oscillating means 7 and the C-axis rotating means 8 are optionally operated, so that the resin material discharged from the nozzle 2a of the discharging means 2 is placed on the receiving member 14. To form a laminate having a desired shape. That is, the moving means (X-axis moving means 4, Y-axis moving means 5 and Z-axis moving means 6), B-axis oscillating means 7 and C-axis rotating means 8 are arbitrarily selected by an instruction from the control means 9. By moving the discharge means 2 and the table 3 relatively to each other, a laminate having a desired shape can be formed on the receiving member 14.

  In particular, by arbitrarily operating the B-axis oscillating means 7 and the C-axis rotating means 8, the resin material can be laminated while rotating the laminate at a predetermined angle, so that the resin material can be laminated upward. Even in the case of molding a laminate having a widened portion (undercut portion), it is possible to prevent the molten resin from sagging downward due to gravity during molding of the undercut portion, which is unnecessary as a product. The molding of the support structure (support structure) can be made unnecessary.

  Further, as shown in FIGS. 26 and 27, a main shaft (spindle) S which constitutes a cutting means together with the discharge means 2 is mounted on the mounting member B1 according to the present embodiment. A cutting tool (bite) 11 capable of cutting the laminated material on the receiving member 14 can be attached to the main spindle S. When the main spindle S is driven, the cutting tool 11 rotates to perform predetermined cutting. It has become.

The magazine 15 accommodates a plurality of types of cutting tools 11 that can be attached to the spindle S. When cutting a laminate, the moving means is optionally operated to move the spindle S of the attachment member B1. It is possible to move the magazine 15 to the position of the magazine 15 and automatically attach a desired cutting tool 11 to the spindle S.

  In the process of discharging the molten resin material from the nozzle portion 2a of the discharge means 2 to form a laminate, the heating means 10 temporarily suspends the molding for cutting by the cutting tool 11, for example, and then returns the molten resin material from the nozzle again. Is discharged, and when the subsequent lamination is performed, the laminated material cooled and solidified by the interruption is heated and melted to enable further lamination. Here, as shown in FIGS. 32 to 36, the heating unit 10 according to the present embodiment includes a box-shaped accommodation unit 10 a capable of accommodating the laminated material on the receiving member 14, and a stacking unit accommodated in the accommodation unit 10 a. And a heater 10b capable of heating an object.

  Specifically, the storage means 10a is formed of a box-shaped member with the internal storage space facing the side at the opening A, and can be inserted into the internal storage space through the opening A through which the laminate is inserted. In addition, a heater 10b for heating the internal storage space by generating heat by energization is attached. Thus, the stacked body on the receiving member 14 can be housed inside the housing means 10a, and the housed stacked body can be heated by the heat generated by the heater 10b.

  Further, the heating means 10 according to the present embodiment is movable by a drive mechanism P as shown in FIGS. The driving mechanism P is mounted on a pinion P1 movable by an actuator such as a cylinder S1, a rack P2 mounted on a moving member H1 connected to the accommodating means 10a and engaged with an upper portion of the pinion P1, and mounted on a fixed member H2. And a rack P3 meshed below the pinion P1. Then, by driving the cylinder S and moving the pinion P1 while rotating, the storage unit 10a can move from the standby position (see FIGS. 32 and 35) to the storage position (see FIG. 36).

  Further, as shown in FIGS. 25, 32, 35, and 36, the heating unit 10 according to the present embodiment is provided on a housing K (in this embodiment, a cover member installed at a position adjacent to the magazine 15). When the driving mechanism P is driven, the housing means 10a is moved from the standby position inside the cover member 13 to the cover member 13 through an opening 13a formed at a predetermined position of the cover member 13. 13 can be moved to and from an external storage position.

  However, in the present embodiment, as shown in FIG. 32, the table 3 (and the receiving member 14) is arranged in the direction in which the housing means 10a of the heating means 10 opens, and as shown in FIG. The table 3 is rocked by about 90 degrees by the shaft rocking means 7 so that the laminate on the receiving member 14 faces the opening A of the storage means 10, and the driving mechanism P is driven to move the storage means 10 a. By moving from the standby position to the storage position, as shown in FIG. 36, the stack can be inserted and stored through the opening A of the storage unit 10a.

  In this way, by rotating the table 3 by the C-axis rotating means 8 in a state where the laminate is accommodated in the accommodation means 10a, the laminate on the receiving member 14 can be heated by the heater 10b while rotating. Have been. In particular, in the present embodiment, by covering the opening A of the storage means 10a with the table 3 (or the receiving member 14), the laminate can be heated by the heater 10b while keeping the inside of the storage means 10a substantially closed. ing. Strictly speaking, a slight clearance is formed between the table 3 and the periphery of the opening A of the storage means 10a, but it is sufficient if the storage means 10a can be made substantially closed.

  Furthermore, the heating unit 10 according to the present embodiment includes a fan 10c that can introduce outside air into the storage unit 10a and allow the air heated by the heater 10b to flow through the storage unit 10a. The fan 10c is mounted on the wall of the housing 10a to which the heater 10b is mounted. The fan 10c operates by energization to introduce outside air into the housing 10a, so that the inside of the housing 10a heated by the heater 10b is heated. Can be circulated around the laminate.

  When the heating by the heating means 10 is completed, the driving mechanism P is driven to move the storage means 10a from the heating position (see FIG. 36) to the standby position (see FIG. 35). Is operated to swing the table 3 back to the normal state (see FIG. 32), and the molten resin discharged from the discharge means 2 is further laminated on the heated laminate. Note that a shutter 13b (see FIG. 25) that closes the opening 13a is attached to the cover member 13, and the shutter 13 is in a closed state except when the laminate is heated. This prevents chips generated during the cutting process from entering the inside of the housing 10a through the opening A.

  According to the present embodiment, the heating unit 10 includes the box-shaped storage unit 10a that can store the stacked product on the receiving member 14, and the heater 10b that can heat the stacked product stored in the storage device 10a. Therefore, after the discharge of the predetermined material and the lamination are interrupted, for example, by cutting with the cutting tool 11, the lamination can be heated sufficiently and evenly, and further lamination can be performed accurately.
