Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1A shows a main configuration of a 3D printer implementing a fragrance material supply according to the present invention, and FIG. 1B shows a configuration of a head part for supplying a discharge material and a perfume material according to the present invention among the configurations of FIG. 1A.

Referring to FIG. 1A, a 3D printer 100 that implements fragrance material supply according to the present invention includes a head part 110 moving in a left and right direction (a) and a vertical direction (b) and supplying a discharge material and a perfume material, And a bed part 120 which moves in the front and back directions (c) and up and down directions (d) and which allows the provided powder to be closely contacted and made to have a desired three-dimensional shape.

Hereinafter, the structure and function of the head unit 110, which allows the perfume material to be supplied in order to achieve a desired perfume in 3D printing, which is a feature of the present invention, will be described.

Referring to FIG. 1B, a head unit 110 for supplying a discharge material and a perfume material according to the present invention includes a discharge material supply unit 111a, a fragrance material supply unit 111b, a housing 112, a heater 113, (114), a screw (115), a mixing space (116), and a motor (117).

The discharge material supply unit 111a supplies discharge materials of various colors (for example, BLACK, MAGENTA, YELLOW, CYAN, etc.) manufactured by the material supplier through the discharge material inlets 111a-1 to 111a-4, By controlling the amount of discharge material, it is possible to produce a three-dimensional molding having a full-color hue of 256 or more steps.

The fragrance material supply unit 111b supplies fragrance materials for generating a desired perfume to the fragrance material inlet ports 111b-1 and 111b-2 separate from the discharge material inlet ports 111a-1 to 111a-4, When the material is melted, it mixes with the fragrance, so that the constituent material coagulates and the fragrance coexists.

In the case of the present invention, the fragrance material is supplied in a liquid state using a predetermined material transfer device (see FIGS. 3A and 3B) or in a gaseous state (see FIGS. 4A and 4B).

This is because the method of supplying in a liquid state is easy to store and can be used directly as a liquid or can be used as a gas by vaporizing a liquid and a method of supplying in a gaseous state can be supplied to a gas directly from an aroma storage container, Because the odor can easily be removed.

Meanwhile, the method of supplying the fragrance material may be a method of supplying the fragrance material with a fragrance mixed solid material, or a method of supplying the fragrance material with the fragrance during the production of the constituent material.

For example, fragrance materials may be contained in a microcapsule to mix fragrance with a solid or a constituent material, and after the product is formed, the fragrance capsule inside and outside the fragrance capsule may be smelled by touching the surface or deforming the shape.

However, in this case, the feedstuff mixed with fragrance is produced and supplied by the material supplier. If the same color is desired, another flavor should be provided. There is a disadvantage that the fragrance gradually disappears.

Next, the housing 112 includes a mixing space 116 and a screw 115. The mixing space 116 forms a constant space of the cylinder to supply the discharge material supply unit 111a and the fragrance material supply unit 111b so that the discharged material and fragrance material introduced into the mixing space 116 can be better blended as the motor 117 is driven.

In this case, the screw 115 adjusts the amount of material ejected through the nozzle 114 by controlling the rotational speed by driving the motor 117. When the interval between the screw 115 and the housing 112 is narrowed (Preferably 5 to 10 μm), the pressure of the substance discharged to the nozzle 114 can be increased, and the size of the nozzle 114 can be reduced accordingly.

The heater 113 is formed so as to surround the outside of the housing 112 and prevents the stagnation phenomenon from occurring when the discharge material and the perfume material introduced into the mixing space 116 are mixed by heating the predetermined heat.

The nozzle 114 adjusts the discharge precision of the material to be supplied in the three-dimensional configuration. When the exit hole of the nozzle is large, the precision of the shape is low, but the speed is fast. It is running slowly.

In this case, it is preferable that the nozzle 114 is constructed to be easily assembled and disassembled so that the screw 115 can be easily cleaned after the separation.

Accordingly, since the color to be discharged at a later time can be blended in consideration of the discharge speed of the material to be supplied, the present invention makes it possible to manufacture various colors in one product.

That is, according to the present invention, it is possible to stop the operation for changing the color at the time of making the shape, to discard the existing color material and to change the color material into the new color material, It is possible to change the color continuously in anticipation of discharge.

FIG. 2 illustrates an inlet cross-section of a head body for supplying a plurality of discharge materials and fragrance materials according to an embodiment of the present invention.

Referring to FIG. 2, a multi-input head for combining various colors and various fragrances is provided. For example, the first to fourth discharge material inlets 111a-1 to 111a- 111a-4 and first and second fragrance material inlets 111b-1, 111b-2 for supplying the first and second fragrance materials.

In this case, it is possible to realize various combinations between the first to fourth discharged materials and the first and second perfume materials by adjusting the kind, amount, speed, and supply time of the supplied materials, And fragrance material inlets.

FIGS. 3A and 3B show the construction of a liquid material transferring apparatus for supplying a liquid material to a material supply unit according to the first and second embodiments of the present invention. FIG.

3A, a liquid material transfer apparatus for supplying a liquid material to a material supply unit according to the present invention comprises a container 10, a filter 20, a regulator 30, a motor 40, a metering pump 50 ), A temperature control jacket 60 and valves V1 to V3.

The container 10 stores the substance 11 to be supplied to the head part 110 and is conveyed to the discharge material 11 or the fragrance material supply part 111b for forming the configuration to be delivered to the discharge material supplying part 111a The perfume material (11) is stored in the inner space.

In this case, the vessel 10 is manufactured by a method such as welding so as to have a structure capable of withstanding high pressure, and is provided with a heat supply (not shown) to surround the outside of the vessel 10 and the outside of the second valve V2 and the metering pump 50 And a temperature control jacket (60) for temperature control.

The reason for covering the temperature control jacket 60 to the outside of the second valve V2 and the metering pump 50 in addition to the container 10 will be briefly described below.

Generally, in the case of a discharged substance, it exists in a solid state at room temperature, and existing products melt the solid to make the liquid, and the liquid is used to form the liquid. When the temperature is lowered, the solid becomes solid.

Therefore, in the container 10 according to the present invention, the solid discharge material is made into a liquid, and this liquid must be transferred to the head part 110.

However, since the solidification starts immediately when the temperature of the liquid supply line is lowered, it is necessary to adjust the temperature through the temperature control jacket 60 in order to deliver the liquid to the head part 110.

On the other hand, in the case of the perfume material, it is not necessary to prevent the coagulation due to the presence of the liquid. However, since the discharge material of the liquid can be hardened by entering the head part 110 in a low temperature state, The heating is performed through the temperature control jacket 60 beforehand.

The container 10 can be heated to a temperature of 500 degrees Celsius through the temperature control jacket 60. In this case, when the storage material is solid, it can be made liquid by raising the temperature of the container to the melting point.

On the other hand, most of the materials are liquefied below 200 degrees Celsius, but in the case of fragrance materials, they become liquid at normal temperature.

The vessel 10 also includes an agitator 12, a residual amount sensor 13, and a temperature sensor 14 in the interior of the vessel 10.

The stirrer 12 stirs the material 11 stored under the interface BL by the rotational force generated by the operation of the external motor 40.

The remaining amount sensor 13 is for measuring the remaining amount of the material 11 stored up to the interface BL. For example, a floating type or an ultrasonic type can be used as the sensor.

The temperature sensor 14 is for measuring the temperature of the substance 11 stored up to the interface BL. For example, TC, RTD and the like can be used as the sensor.

Next, the input terminal (A _in) is a material of a liquid state kept in an inert gas (for example, He, Ar, N, etc.) or using a high-pressure non-moisture air, the vessel 10 to a pressure of the base 11 And supplies the liquid material to the material supply portions 111a and 111b of the head portion 110 connected to the output end C _out in which case the amount of the liquid material supplied due to the pressure control of the used gas is adjusted .

The gas supplied through the input terminal A _in is passed through the filter 20 to remove foreign matter and the like present in the gas and is adjusted to a constant pressure while passing through the regulator 30, When the valve V1 is opened, gas is injected into the container 10 to apply a constant pressure to the liquid material 11 stored therein.

Material supply unit (111a of the next process, the container 10, the second head part 110 is connected to the lower opening the valve (V2) material 11 in constant amount of liquid phase is an output terminal (C _out) in the top of the discharge opening of, 111b.

In this case, a metering pump 50 is additionally provided between the second valve V2 and the output terminal C _out to more precisely control the material 11 of the head part 110 connected to the output terminal C _out It is preferable to supply it to the supply units 111a and 111b.

Next, the replenishing step (B _in ) replenishes the substance (discharge material or fragrance material) to be stored in the container 10 through the opening and closing of the third valve V3.

Here, the supplementary supply means that when the supply amount of the liquid material 11 stored in the container 10 is insufficient to be supplied to the material supply units 111a and 111b of the head unit 110 connected to the output end C _out , And sensing that the valve (V3) is manually or automatically opened to supply the supplementary substance into the container (10).

3B differs from FIG. 3A in that the second valve V2 and the metering pump 50 are provided below the bottom of the discharge port of the vessel 10, and the remaining configurations and functions And therefore redundant description is omitted.

Thus, the second embodiment can be relatively output terminal (C _out) in a low position to facilitate than the supply of the liquid substance (11) using the additional potential energy of the liquid substance 11, the container 10 The liquid material 11 at the bottom of the vessel 10 can also be used and has the technical advantage that the bottom of the vessel 10 can be sloped toward the discharge port to reduce the remaining material.

The liquid material transfer device of the first embodiment and the second embodiment are combined so that the liquid material 11 stored in the container 10 is supplied to the material supply parts 111a and 111b of the head part 110, It is a matter of course that the present invention can be modified so as to be supplied in multiple ways.

In this case, as compared with the liquid material conveying apparatus described in FIG. 3A, the structure and function of the apparatus of the gas material conveying apparatus are largely the same, and only the differences are described below.

First, the input stage A _in is used to pressurize the liquid material 11 stored in the vessel 10 by the pressure of the gas by using an inert gas (e.g., He, Ar, N or the like) And supplies the vaporized material to the material supply units 111a and 111b of the head unit 110 connected to the output stage C _out . In this case, the amount of the liquid material supplied to the pressure control of the used gas is controlled do.

When paraphrase this process, the gas supplied through the input terminal (A _in) is the seventh valve (V7) that when opened, foreign matter, such as by passing through the filter 20 present in the gas is removed, the pressure regulator (35 And when the eighth valve V7 is opened, the amount of gas is adjusted while passing through the flow regulator 45, and the ninth valve V7 and the first valve V1 are opened The gas is injected into the container 10 to apply a constant pressure to the stored liquid material 11 to help vaporize the liquid material.

In this case, in order to help vaporize the liquid material, it is necessary to heat the outer temperature control jacket 60. Hereinafter, this process will be briefly described.

Generally, the main parameters for vaporizing the liquid are temperature, high vaporization at high temperature, and poor vaporization at low temperature.

Since the vaporized material is maintained in a gaseous state by maintaining the temperature, the temperature of the outlet end of the vessel 10 is controlled through the temperature control jacket 60.

On the other hand, as shown in FIG. 4A, it is possible to simply transfer the vaporized material without immersing the introduced gas into the liquid, but in order to vaporize more liquid, a bubbling method of immersing the introduced gas into the liquid is used It is possible.

In this case, when the second valve V2 is opened, the gaseous material passes through the filter 20, removes foreign substances present in the gas, is adjusted to a desired pressure while passing through the pressure regulator 35, And then supplied to the material supply units 111a and 111b of the head unit 110 connected to the output terminal C _out after adjusting the amount of the gas.

3A to 4B, the liquid material 11 stored in the container 10 is supplied to the material supplying units 111a and 111b of the head unit 110, 111b, and 111b, respectively.

FIG. 5A is a diagram showing the structure of a cleaning device when cleaning a liquid material transfer device for supplying a liquid material to a material supply part according to the first embodiment of the present invention. FIG.

5A, the cleaning apparatus according to the first embodiment of the present invention is provided with a fourth valve V4 separately provided between the regulator 30 and the metering pump 50 for cleaning, The liquid material conveying device has the same structure and function as those of the liquid material conveying device.

First, the process of cleaning the material supply line will be briefly described. The gas or the cleaning liquid supplied through the input terminal A _in passes through the filter 20, while the foreign substance existing in the gas or the cleaning liquid is removed, The first valve V1 and the second valve V2 are closed and only the fourth valve V4 is opened to supply the gas or the cleaning liquid to the supply line to clean the supply line.

In this case, it is also possible to clean the housing 112, the screw 115 and the nozzle 114 of the head part 110 by supplying a gas or a cleaning liquid to the head part 110 connected to the output terminal C _out .

Next, the cleaning process of the container 10 will be briefly described. The gas or the cleaning liquid supplied through the input terminal A _in passes through the filter 20, while the foreign substances or the like present in the gas or the cleaning liquid are removed, The fourth valve V4 is closed, and when only the first valve V1 is opened, gas or a cleaning liquid is supplied into the vessel 10 to perform cleaning.

In this case, if the container 10 is brought to a negative pressure, the material in the supply lines connected to the container 10 is forced into the container 10 and collected into the container 10, 11) When replacing, the materials in the supply lines can be reused without throwing away.

Fig. 5B is a second embodiment of the present invention, which shows the structure of a cleaning device when cleaning a liquid material transfer device for supplying a liquid material to a material supply part. Fig.

5B, the cleaning apparatus according to the second embodiment of the present invention includes, in addition to the configuration of the cleaning apparatus according to the first embodiment of FIG. 5A, a metering pump 50 and an output stage C _out) is installed to the one node (the fifth valve (V5) and the sixth valve (V6) is branched via the N1) between features.
