Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forming method for forming a three-dimensional solid having a predetermined shape by sequentially laminating a plurality of sheets, and a three-dimensional solid forming apparatus used for implementing the method.

[0002]

2. Description of the Related Art With the spread of CAD systems, the design of shapes has been rationalized, and not only planar shapes but also three-dimensional shapes can be confirmed on a display. However, a three-dimensional model has been produced to confirm the shape of the product. As a three-dimensional modeling method for producing such a three-dimensional model, there are a photolithography method of irradiating a photocurable resin such as an epoxy-based resin or a urethane-based resin with a laser beam and curing the irradiated portion to form a molded object. -A nozzle is attached to a table that moves on the Y plane, the molten resin is sprayed from the nozzle and stacked in a predetermined shape to form a resin. There are known a powder fixing method, a sheet laminating method, and the like in which a surface is melted, adhered and deposited, and shaped.

As a sheet laminating method, Helisy of the United States
The lamination method proposed by s company is known. The sheet laminating method is a method of laminating a special sheet to which an adhesive is applied, cutting each layer with a carbon dioxide gas laser, and removing unnecessary portions to form the sheet. Further, as another lamination method, for example, a molding method is known as disclosed in Japanese Patent Application Laid-Open No. 7-195533. As described in the same publication, a sheet lamination molding apparatus used for performing the sheet lamination method includes a tray on which sheets are placed, a laser printer for applying an adhesive to a sheet supplied from the tray, A reversing machine for reversing the sheet coated with the adhesive on the entire surface, a conveyor for transporting the sheet from the laser printer unit to the table via the reversing machine, a heater plate for heat-sealing the adhesive, and a cutting device for cutting the sheet into a predetermined shape. And so on. Therefore, a three-dimensional molded object can be manufactured by the sheet laminate modeling apparatus.

[0004]

A three-dimensional object can be produced by any of the conventional three-dimensional object forming methods described above. However, the conventional three-dimensional modeling method has problems or points to be improved. For example, a laser oscillator, a galvanomira, or the like is used to carry out the optical shaping method, but these have disadvantages of being expensive and having a short life. Further, the curing speed of the photocurable resin is slow and expensive. Therefore, there is a disadvantage that the cost is increased as a whole. In the melt deposition method, high-speed molding cannot be performed since the resin must be sequentially deposited after the molten resin is hardened, and the running cost is high because a dedicated resin must be used. The implementation of the powder fixing method requires the use of an expensive laser oscillator or the like as in the case of the optical shaping method, and has the disadvantage that the strength of the manufactured shaped article is low.

[0005] Since the carbon dioxide laser is used in the implementation of the lamination method proposed by Helisys of the United States, the modeling apparatus is expensive. In addition, since unnecessary portions are removed after molding, it is not necessarily an appropriate method for molding a three-dimensional solid having a complicated shape. Furthermore, since the carbon dioxide laser is used for cutting, it emits smoke and requires a smoke exhaust device for that,
Overall, the cost is high. There is also a problem in that a special sheet to which an adhesive is applied must be used for the sheet. In contrast, Japanese Patent Application Laid-Open
In the modeling apparatus disclosed in JP-A-195533, the adhesive strength, the working height position of the cutting means, and the like can be adjusted by the vertical movement of the table on which the sheet coated with the adhesive is placed. It is possible to produce a model with a small modeling error. However, since an expensive and single-life laser oscillator is used to apply the adhesive, the cost cannot be denied. In addition, since the sheet is conveyed from the laser printer to the table by a conveyor, it also requires a reversing machine for reversing the sheet coated with adhesive, an air-conditioned box, etc. Are increasing in size and cost. Further, since the adhesive is applied to the entire surface of the sheet, the area of the heater plate for heat-sealing the adhesive is increased, so that a large pressing force is required and power consumption is expected to increase. . The present invention
3 which has solved the above-mentioned conventional disadvantages or problems.
The purpose of the present invention is to provide a three-dimensional modeling method and a modeling apparatus, specifically, using a plain paper that can be obtained at a low price regardless of the quality and type of a charged sheet, and an expensive and short-life laser. It is used for a three-dimensional solid modeling method capable of obtaining a three-dimensional solid at low cost without using an oscillating system, a conveyor that conveys a sheet that increases costs, a reversing machine that reverses the sheet, and the like, and is used for implementing this method. It is intended to provide a molding device.

Embodiments of the present invention will be described below. As shown in FIG. 1, a three-dimensional three-dimensional printing apparatus according to the present embodiment
It is composed of Then, 3 according to the present embodiment.
Almost all processes for forming a three-dimensional solid are performed around the conductor drum 1 without using a conveyor for conveying a sheet, a reversing device for reversing a surface on which an adhesive is applied, or the like. I have. Therefore, a sheet feeder 10 and a corona charger 2 are provided around the conductive drum 1.

[0008] The three-dimensional three-dimensional modeling process according to the present embodiment is performed in the order of a sheet supply step, a charging step, a cutting step, a peeling step, and the like. Each device constituting the device will be described in this order.

The conductive drum 1 is formed in a substantially cylindrical shape from a conductive metal such as aluminum or an alloy thereof. The conductive drum 1 is grounded by a ground wire 2. Therefore, this conductive drum 1
Is at zero potential. The conductive drum 1 includes an electric motor, and is driven to rotate in the forward and reverse directions at a speed controlled by a control signal from the sequence control device 76.

The sheet feeder 10 includes a tray 11 and feed rollers 12, 1 disposed above the tray 11.
2. It is composed of a guide member 13, a pressing roller 14, and the like arranged near the conductive drum 1. Are sequentially pushed up in the tray 11 by the push-up member 15 according to the amount of use, and are driven at a speed controlled by a control signal from the sequence control device 76. The sheet is fed toward the conductive drum 1 by feed rollers 12, 12 and then the guide member 1
3, the sheet is guided to the pressing roller 14 and supplied to the conductive drum 1 one by one.

The corona charger 20 includes a box-shaped hood 21 in which the direction of the conductive drum 1 is open.
Inside, a corona wire 22 substantially equal to the axial length of the conductive drum 1 is provided. As shown in FIG. 2A, a positive voltage is applied to the corona wire 22 by a line 23, and the hood 21 is grounded by a line 24. Therefore, when the sheet S, which is an insulator, is supplied to the inside of the corona charger 20, the sheet S is positively charged, and is electrostatically attracted or adhered to the outer peripheral surface of the conductive drum 1 at zero potential.

The cutting tool 30 includes a cutter, an end mill, and the like. The cutting edge 31 faces the outer peripheral surface of the conductive drum 1 and has a driving unit 3 at its base.
2 are provided. The drive unit 32 is connected to the sequence control device 76 by a signal line. The driving unit 32 drives the cutting tool 30 in a direction in which the cutting tool 30 is in contact with the outer peripheral surface of the conductive drum 1 and in a direction in which the cutting tool 30 is separated by a data signal output from the 3D data control device 75 as described later in detail. , Is also driven in the axial direction of the conductive drum 1. At this time, the conductive drum 1
It is rotationally driven at a predetermined speed by a data signal output from the 3D data control device 75. Such a combination of the axial movement of the conductive drum 1 and the rotational movement of the conductive drum 1 of the cutting tool 30 causes the sheet to be two-dimensionally attracted to the conductive drum 1. In a predetermined shape.

The peeling machine 40 comprises a plow or plow-shaped cutting edge 41. The cutting edge 41 is formed thin and corrugated as shown in FIG. The driving section 42 drives the cutting edge 41 in a direction tangential to the outer peripheral surface of the conductive drum 1 and in a direction away from the outer peripheral surface. This allows
Unnecessary portions of the sheet cut by the cutting tool 30 are peeled off and removed from the surface of the conductive drum 1 and discharged by a pair of sandwiching rollers 43, as described in the modeling step. The drive section 42 is also driven by a control signal from the sequence control device 76.

The adhesive applicator 50 includes a magnet roll 51 for supplying a charged adhesive to the conductor drum 1 and a hopper surrounding the magnet roll 51 and storing the charged adhesive therein. Have been. The magnet roll 51 has an axial length substantially equal to the length of the conductive drum 1 and, like the developing device of the electrophotographic copying machine, includes a magnet shaft on which a magnet is arranged, and a magnet shaft. A concentrically surrounding conductive sleeve. That is, the magnet shaft has a double structure including a fixed magnet shaft and a conductive sleeve that rotates around the magnet shaft.
A positive voltage of the DC voltage 55 and an AC voltage 54 higher than the positive voltage are applied to the magnet shaft by the power line 53 in a superimposed manner. As described above, although the high AC voltage 54 is applied to the magnet shaft, the positive voltage 55 is also applied, and the sheet is positively charged. The given one is used. The conductive sleeve is electrically connected to the magnet shaft, and a magnetic field is generated between the conductive sleeve and the conductive drum 1. Selectively adheres to the sheet of the two-dimensional image. Note that 000 or the like is used as the charging adhesive.

In the present embodiment, the heater 60 comprises a heating lamp 61 and a reflector 62 facing the conductor drum 1. The heater 60 is arranged at a position separated from the adhesive applicator 50 so that the charged adhesive is not thermally affected. The heater 60 is also controlled by a control signal from the sequence controller 76.

The modeling table 70 comprises a movable table 71 having a predetermined area which is driven vertically and horizontally. The drive section 72 is connected to the sequence controller 76 via a signal line, not shown in the figure. The movable table 71 is moved in a direction in which the movable table 71 is pressed against the outer circumferential surface of the conductive drum 1 with a predetermined force by a control signal sent from the sequence control device 76, in a direction in which the conductive table 1 is separated, and further in a rotational direction and speed of the conductive drum 1. They are driven in the horizontal direction in synchronization. As a result, the two-dimensional image sheet is cut on the conductive drum 1 and the sheet on which the charging adhesive is applied and melted is sequentially laminated on the movable table 71 to obtain a three-dimensional solid image, that is, a three-dimensional solid. Will be.

FIGS. 2 and 3 are views schematically showing a three-dimensional solid forming process according to the present embodiment. Hereinafter, mainly referring to these figures, FIG. 1 and FIG. A method of forming a three-dimensional solid indicated by reference numeral M will be described. For example, the shape of the three-dimensional solid M is designed by a three-dimensional CAD system. In the 3D data control device 75, the shape information of the three-dimensional solid M is sequentially sliced in the horizontal direction to a thickness corresponding to one thickness of the sheets S, S,. Obtain two-dimensional data. Thus, the two-dimensional data corresponding to each sheet S, S,... Is sent from the sequence control device 76 to the various driving units 32, 42, 72, etc., and a two-dimensional image in each sliced cross section is obtained.

Sheets S made of insulating paper, resin film or the like are sent to the conductor drum 1 one by one based on a feed signal. Since the corona wire 22 of the corona charger 20 is given a positive potential, the sheet S is positively charged. The state in which the sheet S is sent to the conductor drum 1 and is positively charged and electrostatically adheres to the outer surface of the conductor drum 1 is shown in FIG.

The conductive drum 1 is rotated by a predetermined amount, and the sheet S
Reaches the position of the cutting tool 30. Then, the cutting edge 31 is driven to a position where the sheet S can be cut, as shown in FIG. Also,
The first two-dimensional data is sent from the sequence control unit 76 to the driving unit 32, and the cutting edge 31 of the cutting tool 30 is sent.
Are driven in the axial direction based on the transmitted two-dimensional data. At the same time, the conductive drum 1 is driven to rotate in the forward and reverse directions at a controlled speed by the first two-dimensional data. As shown in FIG. 2D, a sheet m of a two-dimensional image is obtained from the sheet S on the conductive drum 1 by a combination of the two movements of the cutting edge 31 of the cutting tool 30 and the conductive drum 1. Can be Sheet m of this two-dimensional image
Will be placed first on the movable table 71.

As described above, the sheet m of the two-dimensional image is cut from the sheet S, and the sheet S ′ to be removed still adheres to the conductive drum 1. Then, the cutting edge 41 of the peeling machine 40 comes into contact with the surface of the conductive drum 1, and the conductive drum 1 is driven about one turn in the direction shown in FIG. Then, the leading end of the sheet S ′ to be removed rides on the cutting edge 41. Then, the cutting edge 41 is separated from the surface of the conductive drum 1. When the conductive drum 1 is further driven in the direction of the arrow, the remaining sheet S 'without the sheet m of the two-dimensional image is guided by the upper surface of the peeling machine 40, and is discharged by the discharge rolls 43, 43. Due to this processing, only the sheet m of the two-dimensional image remains on the outer peripheral surface of the conductive drum 1.

The conductive drum 1 to which the sheet m of the two-dimensional image adheres rotates by a predetermined amount, and reaches the position of the adhesive applicator 50. Since a positive voltage of the DC voltage 55 and an AC voltage 54 higher than the positive voltage are applied to the magnet shaft in a superimposed manner by the power line 53, the conductive sleeve and the conductive drum 1 A magnetic field is generated therebetween, and the charged adhesive on the conductive sleeve moves violently between the conductive sleeve and the sheet m of the two-dimensional image.
When the roller rotates and the distance from the sleeve increases, the movement of the charged adhesive rapidly stabilizes and uniformly adheres to the two-dimensional image sheet m. The charging adhesive at this time is shown in FIG.
Are indicated by a number of minus signs "-".
Since the conductive drum 1 is grounded, the surface of the conductive drum 1 does not have a charging adhesive.

When the conductive drum 1 further rotates by a predetermined amount and reaches the position of the heater 60, the lamp 61 is energized and
The charged adhesive on the two-dimensional image sheet m is melted. FIG. 3 shows a state in which the lamp 61 is melted by radiant heat.
(B).

Further, the conductive drum 1 rotates by a predetermined amount and reaches the position of the movable table 71. This position is accurately positioned based on the two-dimensional data sent from the sequence controller 76. The movable table 71 is a driving unit 72
, And is pressed against the conductive drum 1 at a predetermined pressure. The movable table 71 moves in the horizontal direction in synchronization with the rotation of the conductive drum 1. 2D image sheet m
In other words, since the charging adhesive is applied to the lower surface in FIG. 3C, the first two-dimensional image sheet m arrives on the movable table 71. At this time, since the adhesive force of the charged adhesive is larger than the electrostatic attraction force,
The sheet m of the two-dimensional image separates from the conductive drum 1 and arrives at the movable table 71. Thereafter, the movable table 71 is retracted to its original position below and to the right in FIG. In the same manner, the sheet S is positively charged, cut into a two-dimensional image sheet m, then coated and melted with a charged adhesive, and sequentially laminated, as shown in FIG. 1 or FIG. Is obtained.

The present invention can be implemented in various forms without being limited to the above embodiments. For example, in the above embodiment, since the charging adhesive is also applied to the surface of the first two-dimensional image sheet m, it is fixedly positioned on the movable table 71, and the position of the subsequent laminate is stable. However, since the sheet m of the first two-dimensional image must be removed from the movable table 71 after modeling,
It is also possible to carry out in a temporarily fixed state without attaching a charging adhesive.

In the above embodiment, one two-dimensional image sheet m is laminated by about 2.5 rotations of the conductive drum 1. However, the corona charger 20, the cutting tool 30, the adhesive It is obvious that the agent applicator 50, the molding table 70, and the like can be arranged in the order of the processes, and one rotation of the conductive drum 1 can stack one two-dimensional image sheet m. At this time, the cutting tool 30, the adhesive applicator 50, and the like may be appropriately retracted from the periphery of the conductive drum 1, for example, to alternately retract. Further, in a state in which a plurality of sheets are constantly adsorbed at appropriate places on the conductive drum 1, cutting of the sheet m of the two-dimensional image, application of the charging adhesive, melting of the charging adhesive, and the like are appropriately performed. It is clear that you can.

In the above-described embodiment, the peeling machine 40 is provided to remove the remaining portion of the two-dimensional image other than the sheet m. After the lamination, it is also possible to implement a finishing step or a removing step so as to remove the remaining portion. Further, the charging adhesive can be melted by heating from inside the conductive drum 1 during lamination. In the above-described embodiment, the sheet S is positively charged and the charged adhesive is negatively charged. However, it is apparent that the operation can be performed with the opposite polarity.

In the above embodiment, a charged adhesive is used as the adhesive, but an adhesive that does not require heating, for example, a synthetic rubber adhesive may be used. When such an adhesive is applied, the heater 60 becomes unnecessary and the structure is simplified.

[0028]

As described above, according to the present invention, a cutting step of cutting a charged sheet into a sheet of a two-dimensional image having a predetermined shape on a conductive drum, and a step of cutting the conductive drum onto the sheet obtained in the cutting step. An adhesive application step of applying an adhesive on the above, and a laminating step of pressing and bonding the surface on which the adhesive is applied to a previously laminated sheet, thereby separating the sheet from the conductive drum and laminating the sheet. In other words, since each of the above-described steps is performed on a conductive drum, plain paper that can be obtained at low cost regardless of quality, type, etc. is used as long as the sheet is charged. be able to. Further, there is no need to use an expensive and short-life laser oscillation system, a costly conveyor for conveying a sheet, or a reversing machine for reversing the sheet. Therefore, according to the present invention, it is possible to greatly reduce the initial cost and the running cost, and obtain an effect that a three-dimensional solid can be obtained at low cost. According to another aspect of the present invention, the adhesive application step of electrostatically applying the adhesive is performed on the two-dimensional image sheet obtained in the cutting step, that is, the sheet part of the two-dimensional image from the sheet. Is removed, so that the charged adhesive is applied only to the sheet of the two-dimensional image, so that the amount of the charged adhesive used is small, and the energy when heating for melting is also reduced. Further, the effect that the pressing force at the time of lamination is small can be added. Thus, the third aspect of the present invention
Cutting process, which is a component of 3D modeling,
Since the adhesive application step, the laminating step, and the like are performed on the conductive drum on which the charged sheet is adsorbed, the three-dimensional three-dimensional modeling apparatus used for performing this method can be configured to be compact, and therefore, relatively small. The effect that can be stored also in a casing is acquired.
