Description

  The present invention relates to a shaping apparatus and a method of manufacturing a shaped article.

  Conventionally, a modeling apparatus (so-called 3D printer) that generates a three-dimensional structure based on given data is known (e.g., Patent Document 1). Also, in recent years, 3D printers are becoming smaller and less expensive so that individual users can use them at home.

  A typical configuration example of a 3D printer includes a relatively movable table and a head. A forming material such as filamentous ABS resin or PLA resin is supplied to the head, the forming material is heated to a melting point in the head, and is discharged from a nozzle of the head in a fluid state. The 3D printer forms a three-dimensional structure by laminating forming materials in a fluid state while moving the table and the head relative to each other.

  By the way, since the forming material discharged from the nozzle solidifies and shrinks due to the decrease of the temperature, the forming object formed on the table is also deformed. Deformation of the shaped object leads, for example, to a displacement of the stacking position of the shaped material, which leads to a failure in the production of the shaped object.

  In order to prevent the failure as described above, in general, fine asperities are formed on the table upper surface (or the pad upper surface laid on the table), and the bottom surface of the object is engaged with and fixed to the asperities. It is being done. If the failure due to the shrinkage of the object can not be prevented, for example, the shrinkage is reduced by keeping the object at a predetermined temperature using a heated bed, or the surface of the table (or the upper surface of the pad) is solidified by drying or heat. Measures have been taken to apply in advance a glue (which may be called an adhesive) to make the bottom of the shaped article more firmly fixed.

  Here, a considerable amount of hand power is required to peel off a shaped object fixed on the table upper surface (or pad upper surface) (or fixed via glue). Preparation of a three-dimensional structure including such a peeling operation involves preparation and post-processing by hand, which requires time and effort. It has not been realized to automatically form a plurality of shaped objects continuously.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1: is a schematic diagram which shows the structural example of the modeling apparatus 1 which concerns on one Embodiment of this invention. In the following description, the left-right direction of the modeling apparatus 1 is taken as an X axis, the up-down direction as a Y-axis, and the front-rear direction as a Z-axis. It is assumed that the XZ plane is horizontal and the ZY plane is vertical.

  The modeling apparatus 1 laminates a material layer made of a modeling material on the table 3 in accordance with modeling data (eg, tool path data generated by slicing STL data) input from a data output apparatus such as a personal computer, for example. Is an apparatus for forming (forming) the three-dimensional structure P. The modeling apparatus 1 can also be called a 3D printer.

  Specifically, the modeling apparatus 1 includes a housing 2, a table 3, a table moving mechanism 4, a guide member 5, a head 6, a head moving mechanism 7, a cartridge 8, a modeling material 9, and a controller 10. The head 6 and the head moving mechanism 7 correspond to a forming unit (forming unit).

  The housing 2 is, for example, a box for the purpose of preventing a temperature drop inside the housing 2. A door may be provided in a partial area of the housing 2, for example, the front. Further, an opening (not shown) in which a guide member 5 described later is inserted and disposed is provided in a partial region of the housing 2, for example, a side surface.

  The table 3 is a base for forming the object P by laminating the forming material dissolved thereon. The table 3 may be equipped with a heater that heats its upper surface, and may function as a heated bed. The table 3 can also be called a stage, a bed, a platform or the like.

  In the present embodiment, the table 3 includes an elevation mechanism 34 (FIG. 4) that changes the height of a partial area of the upper surface. By changing the height of a part of the area by the lifting mechanism 34, the bottom surface of the three-dimensional object P fixed to the table 3 can be peeled off automatically. The lifting mechanism 34 will be described in detail later.

  The table moving mechanism 4 is a mechanism that supports the table 3 from the lower side and moves the table 3. The table moving mechanism 4 can move the table 3 in the Y axis direction. Although the structure of the table moving mechanism 4 is not specifically limited, For example, it can comprise from mechanical components, such as a motor, a gear, a rail, a belt.

  In the present embodiment, the table moving mechanism 4 can tilt the table 3 in at least one direction with respect to the reference plane parallel to the XZ plane (tilting mechanism). For example, as shown in FIG. 2 (a schematic view showing an example of the tilting operation of the table 3), the table moving mechanism 4 tilts the table 3 left lower or lower right by rotating around an axis parallel to the Z axis. You can tilt it. Thereby, the three-dimensional object P whose adhesion to the table 3 has been released can be slid to the outside of the table 3 and dropped. The larger the inclination angle, the easier it is for the object 3 to slide down, so the maximum inclination angle of the table 3 is desirably 90 degrees (with respect to the reference surface 0 degree).

  The guide member 5 is a plate-like member disposed below the table 3 and receives the shaped object P which has slipped off due to the table 3 being inclined, and the predetermined region in the shaping apparatus 1 or the outside of the shaping apparatus 1 Slide and lead to a predetermined area of The predetermined area is, for example, a case for housing the object P, a conveyor for conveying the object P, or the like.

  In the example of FIG. 2, the guide member 5 of right and left 2 places is provided, each penetrates the opening (not shown) formed in the housing | casing 2, and is extended outside. Each guide member 5 forms an inclined surface which becomes lower toward the outside. The object P which has slipped off the table 3 inclined to the left is received by the guide member 5 on the left side, is slid thereon, and is led out of the left side of the housing 2. The object P which has slipped off the table 3 inclined to the right is received by the guide member 5 on the right and slid thereon, and is led out of the right of the housing 2.

  The head 6 heats the build material 9 supplied from the cartridge 8 and discharges the melted build material from the nozzle at the tip. A feed mechanism (not shown) for supplying the filament-shaped build material 9 to the head 6 is provided inside the head 6 or outside the head 6. The configuration of the feed mechanism is not particularly limited, but can be composed of, for example, mechanical parts such as motors, gears, and rollers.

  The head moving mechanism 7 is a mechanism that holds the head 6 and moves the head 6. The head moving mechanism 7 can move the head 6 in the X axis direction and the Z axis direction. The head moving mechanism 7 may move the head 6 in the Y-axis direction. The configuration of the head moving mechanism 7 is not particularly limited, but may be, for example, mechanical components such as motors, gears, rails, and belts.

  The cartridge 8 is wound with a forming material 9 such as filamentary ABS resin or PLA resin, and is configured to be able to draw out the forming material 9. The tip of the build material 9 is withdrawn from the cartridge 8 and loaded into the above-described feed mechanism.

  The controller 10 integrally controls the overall operation of the modeling apparatus 1. For example, the controller 10 may control the head moving mechanism 7 and the table based on data for modeling transmitted from a data output device (personal computer, smartphone, server computer, computer on cloud, etc.) or read from a recording medium. The moving mechanism 4 is controlled to move the shaping position (the relative position of the head 6 and the table 3) of the head 6 above the table 3. In addition, the controller 10 controls the head 6 to melt and laminate the forming material at the forming position. A modeling material is laminated by repetition of such processing, and modeling thing P is modeled.

  Moreover, the controller 10 controls the raising / lowering mechanism 34 mentioned later, and peels off the bottom face of the modeling thing P from the table 3, after modeling of the modeling thing P is completed. Then, the controller 10 controls the table moving mechanism 4 to tilt the table 3 and slide the object P off. Since the produced modeling thing P is carried out from the table 3 by such processing, modeling of the next modeling thing P can be started.

  The controller 10 can be realized by, for example, a computer having a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), a communication interface, a display, an input device, a reader of a recording medium, and the like. The controller 10 may have a circuit such as a dedicated image processing circuit other than the CPU. The functions and processing of the controller 10 can be realized, for example, by the CPU executing a predetermined program.

  FIG. 3 is a perspective view showing an example of the appearance of the table 3. The table 3 includes a frame body 31, a plurality of first table areas 32, and a plurality of second table areas 33. In the illustrated example, the area around the plurality of second table areas 33 is a continuous integrated area. However, this area can be understood as a plurality of first table areas 32 divided for convenience. The plurality of first table areas 32 and the plurality of second table areas 33 are provided inside the frame body 31 and constitute the upper surface of the table 3. The plurality of first table areas 32 and the plurality of second table areas 33 are geometrical shapes, and are alternately arranged in a two-dimensional direction (X-axis direction and Z-axis direction).

  Preferably, the ratio of the area of the first table area 32 to the area of the second table area 33 is approximately the same so that the area peeled off by the elevating operation described later is approximately the same.

  The geometrical shapes of the first table area 32 and the second table area 33 are not limited to quadrangles as shown in FIGS. 3 and 10A, but may be triangles as shown in FIG. 10B. It may be a polygon or more, or it may be a rounded corner of the polygon. Further, the number of each of the first table area 32 and the second table area 33 is not limited to the illustrated example, and their arrangement may be random.

  As shown in FIG. 10C, the plurality of rectangular second table areas 33 may be arranged in an oblique direction with respect to the X-axis direction and the Z-axis direction. Further, as shown in FIG. 11A, a plurality of second table areas 33, which are polygons (polygons formed by cutting out in the diagonal of a rectangle), are made with respect to the X axis direction and the Z axis direction. It may be arranged in an oblique direction. Further, as shown in FIG. 11B, the second table area 33, which is a set in which two line-symmetrical triangles are shifted in the Z-axis direction, is diagonally set with respect to the X-axis direction and the Z-axis direction. It may be arranged in Further, as shown in FIG. 11C, the second table area 33, which is a set in which two triangles are arranged in line symmetry, may be arranged diagonally with respect to the X axis direction and the Z axis direction. . In these arrangement patterns, there is no region that is linearly continuous in the X-axis direction and the Z-axis direction between the plurality of second table regions 33. Therefore, for example, when the elongated object P is disposed along the X-axis direction or the Z-axis direction, the bottom surface is in contact with both the plurality of first table areas 32 and the plurality of second table areas 33.

  FIG. 4 is a schematic view showing a configuration example of the lifting and lowering mechanism 34 of the table 3. (A) shows a state in which the second table area 33 is positioned at a reference height, and (B) shows a second table area 33. The lowered state, (C) shows the second table area 33 raised. FIG. 4 shows the XY cross section of the table 3 of FIG.

  The plurality of first table areas 32 are fixed to the frame body 31 so that the upper surface thereof coincides with the reference height position H of the upper surface of the table 3 as shown in FIGS. 4 (A) to 4 (C) It is done.

  On the other hand, as shown in FIGS. 4A to 4C, the plurality of second table areas 33 can move up and down the height of the upper surface thereof. For example, the plurality of second table areas 33 are held by the elevating mechanism 34 disposed below them, and can be moved up and down by the elevating operation of the elevating mechanism 34. The structure of the lifting mechanism 34 is not particularly limited, but can be composed of, for example, mechanical parts such as motors, gears, rails, and cylinders.

  In FIG. 4A, the plurality of second table areas 33 are positioned such that the upper surfaces thereof coincide with the reference height position H of the upper surface of the table 3. There is no level difference between the upper surface of the second table area 33 and the upper surface of the first table area 32, and the upper surface of the table 3 becomes flat. In FIG. 4B, the plurality of second table areas 33 are positioned such that the upper surface thereof is lower than the reference height position H of the upper surface of the table 3. A step G1 is generated on the upper surface of the second table area 33 and the upper surface of the first table area 32. In FIG. 4C, the plurality of second table areas 33 are positioned such that the upper surface thereof is higher than the reference height position H of the upper surface of the table 3. A step G2 is generated on the upper surface of the second table area 33 and the upper surface of the first table area 32.

  FIG. 5 is a schematic view showing an operation example of the lifting and lowering mechanism 34 of the table 3. (A) shows a state in which the second table area 33 is positioned at a reference height, (B) shows a second table area 33. The lowered state, (C) shows the second table area 33 raised.

  First, in the state shown in FIG. 5A, the bottom surface of the three-dimensional object P is fixed to the upper surfaces of the plurality of first table regions 32 and the upper surfaces of the plurality of second table regions 33. In the case where a paste (which may be called an adhesive) which solidifies by drying or heat is previously applied to the upper surface of the table 3, the adhesive is further strongly fixed via the fixing layer.

  Next, as shown in FIG. 5B, when the plurality of second table areas 33 are lowered lower than the reference height position H, a step G1 is generated. The top surface of the table area 33 is peeled off. In this state, the bottom surface of the object P is still adhered to the top surfaces of the plurality of first table areas 32.

  Next, as shown in FIG. 5C, when the plurality of second table areas 33 are raised higher than the reference height position H, a step G2 is generated. The top surface of the table area 32 is pulled off. In this manner, the bottom surface of the three-dimensional object P is released from the upper surfaces of the plurality of first table regions 32 and the upper surfaces of the plurality of second table regions 33.

  FIG. 6 is a flowchart showing an example of the operation of the modeling apparatus 1. This flowchart is started, for example, after the power of the modeling apparatus 1 is turned on.

  First, the controller 10 determines whether or not an instruction for forming a modeling object P, which is the next modeling object, has been received (step S1). For example, the controller 10 determines whether or not a modeling instruction including modeling data has been received from the data output device via the communication interface. The controller 10 repeats the process of step S1 until it is determined that the shaping instruction has been received (NO in step S1).

  When it is determined that the next modeling instruction has been received (YES in step S1), the controller 10 executes a modeling process (step S2). For example, the controller 10 controls the head moving mechanism 7 and the table moving mechanism 4 based on the modeling data received in step S1 to set the modeling position of the head 6 above the table 3 (the relative position of the head 6 and the table 3) Move). In addition, the controller 10 controls the head 6 to melt and laminate the forming material at the forming position. By repeating such a process, a modeling material is laminated | stacked and the modeling thing P instruct | indicated by step S1 is modeled.

  Next, the controller 10 executes the peeling process of the object P (step S3). For example, the controller 10 controls the elevating mechanism 34 to repeat the elevating operation (FIGS. 5B and 5C) of the second table area 33 one or more times. Thereby, the bottom of the three-dimensional object P peels from the upper surface of the table 3. Thereafter, the controller 10 returns the second table area 33 to the reference height position H (FIG. 5 (A)).

  Next, the controller 10 executes an unloading process of the object P (step S4). For example, the controller 10 controls the table moving mechanism 4 to tilt the table 3. As a result, the object P slides from the table 3 and slides down on the guide member 5 and is conveyed by the guide member 5 to a predetermined area. Thereafter, the controller 10 returns the inclination of the table 3 to the initial posture (horizontal), and returns the process to step S1.

  In addition, peeling process and conveyance process are not limited to the example shown to the above-mentioned flowchart. For example, after tilting the table 3, the controller 10 may perform peeling processing in that state, and then return the table 3 to the initial posture. Even in this manner, the object P can be slid down.

  Further, in step S4, the controller 10 may sort the three-dimensional object P so as to be carried out of any of the plurality of guide members 5. As a specific example, the controller 10 selects a guide member 5 different from the guide member 5 that has slipped the previous three-dimensional object P, and tilts the table 3 toward the selected guide member 5. As another specific example, the identifier of one of the guide members 5 is included in the shaping instruction, and the controller 10 tilts the table 3 toward the guide member 5 designated by the shaping instruction.

  Heretofore, an embodiment of the present invention has been described. According to the modeling apparatus 1 of the present embodiment, the process of peeling the modeled object P from the table 3 can be automated. In addition, continuous formation of a plurality of three-dimensional object P can be automated.

  By the way, in the above-mentioned embodiment, a user needs to perform application to the upper surface of table 3 of adhesives. In order to automate this operation, the table 3 of the modeling apparatus 1 may be provided with a discharge mechanism of an adhesive. The details will be described below.

  FIG. 7 is a schematic view showing a configuration example of the adhesive material discharge mechanism. In the inside of the table 3, a flow path 35 for flowing a liquid or gel adhesive is provided. The inlet 36 of the flow path 35 is connected to an adhesive cartridge (not shown) filled with an adhesive provided outside the table 3. The flow path 35 is branched into a plurality of branches, and the outlet 37 of each branch is formed on the upper surface of the second table area 33. For example, a pump (not shown) is provided between the adhesive cartridge and the flow path 35, and the adhesive flows through the flow path 35 by the force of the pump and is discharged from the outlets 37. The operation of this pump is controlled by the controller 10.

  Of course, the ejection of the adhesive is not limited to the pump mechanism, and may be controlled by, for example, a piezo element or a heater provided in the vicinity of the outlet 37 by applying the technology of a printer using ink. Therefore, the mechanism for discharging these adhesives can be called, for example, a discharge control unit. In the case where the adhesive is in the form of liquid or gel which can not maintain its shape, the adhesive cartridge functions as an adhesive tank. On the other hand, if the adhesive is in the form of a gel that can maintain its shape, the adhesive cartridge is configured, for example, such that a filamentous adhesive is wound so that the adhesive can be pulled out. There is. The drawn adhesive is supplied to the inlet 36 of the flow path 35.

  The adhesive discharged from each outlet 37 is melted by the heat of the head 6 brought close to the table 3 and spreads on the upper surface of the table 3 by its weight, and then is radiated and solidified to form a fixing layer. The adhesive used here can be made solid, having the property of melting by heat of a predetermined temperature or more and solidifying by heat radiation. By forming the three-dimensional object P on the upper surface of the table 3 through the fixing layer, it can be more firmly fixed.

  The arrangement of the plurality of outlets 37 is not limited to the example shown in FIG. For example, it may be provided in a plurality of first table areas 32, or may be provided in both of a plurality of first table areas 32 and a plurality of second table areas 33.

  FIG. 8 is a schematic view showing another configuration example of the adhesive material discharge mechanism. The modeling apparatus 1 further includes an adhesive head 11 and an adhesive cartridge 12 as compared with FIG. 1. The adhesive head 11 discharges the adhesive supplied from the adhesive cartridge 12 from the nozzle at the tip. For example, a pump (not shown) is provided between the adhesive cartridge 12 and the adhesive head 11, and the adhesive is supplied to the adhesive head 11 by the force of the pump. The operation of the pump and the operation of the adhesive head 11 are controlled by the controller 10. The head moving mechanism 7 can hold the adhesive head 11 and move the adhesive head 11 in the X-axis direction and the Z-axis direction.

  Of course, the discharge of the adhesive is not limited to the pump mechanism, and may be controlled by, for example, a piezo element or a heater provided at the nozzle of the adhesive head 11 by applying the technology of a printer using ink. Therefore, the mechanism for discharging these adhesives can be called, for example, a discharge control unit.

  The adhesive discharged from the nozzle of the adhesive head 11 is melted by the heat of the closely arranged head 6 and is applied to the upper surface of the table 3. Then, it spreads on the upper surface of the table 3 by its weight, and thereafter it is radiated and solidified to form a fixing layer. The adhesive used here can be made solid, having the property of melting by heat of a predetermined temperature or more and solidifying by heat radiation. By forming the three-dimensional object P on the upper surface of the table 3 through the fixing layer, it can be more firmly fixed.

  FIG. 9 is a flowchart showing another example of the operation of the modeling apparatus 1. In the flowchart of FIG. 9, step S5 is inserted between step S1 and step S2 as a point different from FIG. 6.

  When it is determined that the shaping instruction has been received (YES in step S1), the controller 10 executes a process of forming a fixing layer (step S5).

  For example, the case where the modeling apparatus 1 includes the discharge mechanism shown in FIG. 7 will be described. The controller 10 controls the discharge control unit to flow the adhesive in the flow path 35 and discharge a predetermined amount from each outlet 37. Further, the controller 10 moves the position of the head 6 above the table 3 (the relative position of the head 6 and the table 3) and heats the head 6 in the vicinity of the outlet 37 to melt the discharged adhesive. By stopping the heating of the head 6 and moving it away from the outlet 37, the melted adhesive is solidified. By performing such processing on each outlet 37, a fixing layer is formed.

  For example, the case where the modeling apparatus 1 includes the discharge mechanism shown in FIG. 8 will be described. The controller 10 controls the head moving mechanism 7 and the table moving mechanism 4 to move the position of the adhesive head 11 above the table 3 (the relative position of the adhesive head 11 and the table 3). In addition, the controller 10 controls the discharge control unit and the adhesive head 11 to eject the adhesive at a predetermined position. Further, the controller 10 heats the head 6 disposed close to the adhesive head 11 to melt the discharged adhesive, stop heating the head 6 and move it away from the position. Solidify the melted adhesive. By performing such processing for each position, a fixing layer is formed. The plurality of positions for discharging the adhesive may be spaced apart in a certain area which is the same as or wider than the bottom surface of the object P.

  By using the above-described discharge mechanism, the process of generating the fixing layer can also be automated.

  In the above-described discharge mechanism, a solid adhesive is used, and is melted by the heat of the head 6 and solidified by heat radiation. In a modification of the ejection mechanism, an adhesive having a property of solidifying by heat or drying may be used. Specifically, for example, a gel or liquid adhesive is used, which is discharged onto the upper surface of the table 3 and solidified by heating the adhesive spread by its weight with the heat of the head 6.

  Further, in the above-described discharge mechanism, the heat of the head 6 is used to heat the adhesive. In a modification of the discharge mechanism, the table 3 may be provided with a heater for heating its upper surface (the table 3 has the function of a heated bed), and the heat may be used to heat the adhesive.

  Further, in the above-described discharge mechanism, the heat of the head 6 is used to heat the adhesive. In a modification of the ejection mechanism, the adhesive head 11 may be provided with a heater, and the heat may be used to heat the adhesive.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention, and these embodiments are included. Some components of one embodiment may be added to another embodiment or replaced with components of another embodiment. Of the components of an embodiment, some components may be omitted.

  For example, the modeling apparatus 1 may include one guide member 5 or three or more guide members 5. In this case, the table moving mechanism 4 may have a mechanical structure for tilting the table 3 toward the one or more guide members 5.

  For example, modeling device 1 may be provided with the machine structure for modeling not only with a single color but with two or more colors.

  Moreover, in the modeling apparatus 1 according to the above-described embodiment, the table moving mechanism 4 can move the table 3 in the Y axis direction, and the head moving mechanism 7 moves the head 6 in the X axis direction and the Z axis direction. Can. However, the configuration is not limited to such a configuration as long as the modeling position can be moved in the three-dimensional direction. For example, the table moving mechanism 4 can move the table 3 in the XYZ axial directions, and the head moving mechanism 7 may be fixed. Also, for example, the table moving mechanism 4 may be fixed, and the head moving mechanism 7 may be able to move the head 6 in the XYZ directions. Moreover, the table moving mechanism 4 may be able to rotate the table 3 around an axis parallel to the Y axis.

  Moreover, in order to make the processing operation of the modeling apparatus 1 easy to understand, the step unit of the flowchart shown by FIG. 6, 9 is divided | segmented according to the main processing content.
