Summary of Invention

Problems to be Solved by the Invention

[0005] Incidentally, when manufacturing a predetermined laminated product using a lamination molding apparatus, it is desirable that the lamination process be carried out without foreign matter such as fine particles or dust adhering to the laminated material or the laminate itself. However, inside the housing of the lamination molding apparatus, an upward airflow is generated due to the heat generated by heating, which makes it easy for foreign matter to accumulate on the inner walls of the housing, and there was a risk that the accumulated foreign matter would adhere to the laminated material or the laminate itself.

[0006] This invention has been made in view of the above circumstances, and aims to improve the yield of laminated molded products by increasing the cleanliness inside the housing. [Means for solving the problem]

[0007] An additive molding apparatus according to one embodiment comprises a housing, a pressurizing unit provided inside the housing and pressurizing a molded product in which laminated material has been laminated onto a workpiece by a pressurizing mechanism arranged vertically, and a fan provided on the top surface of the housing and supplying a downward airflow that flows downward into the housing, wherein the housing has an exhaust port on at least one surface other than the top surface for discharging exhaust air caused by the downward airflow.

[0008] A lamination molding system according to one embodiment includes a laminator having a pressurizing section that pressurizes a primary molded product, which has a laminate layer laid on a workpiece, by pressurizing it with pressurizing mechanisms arranged above and below, and a flattening press device that pressurizes the primary molded product with an improved flatness of the laminated surface of the laminate layer by pressurizing mechanisms arranged above and below, wherein at least one of the laminator and the flattening press device has a fan on the top surface of the housing that supplies a downward airflow that flows downward into the housing.

[0009] In one embodiment of the laminated molding apparatus and laminated molding system, a fan is provided to supply downward airflow within the housing in which the pressurizing unit is built, thereby preventing foreign matter inside the housing from convection or accumulating within the housing. [Effects of the Invention]

[0010] According to one embodiment of the laminated molding apparatus and laminated molding system, the molding accuracy of the molded product can be improved by increasing the cleanliness inside the housing. [Brief explanation of the drawing]

[Figure 2] This is a diagram showing the configuration of a laminator according to Embodiment 1. [Figure 3] This diagram illustrates the airflow in a laminator in a comparative example.

[Figure 6] This diagram illustrates the airflow in a laminator according to Embodiment 2. [Figure 7] This diagram illustrates the airflow in a laminator according to Embodiment 3. [Figure 8] This is a diagram showing the configuration of a laminator according to Embodiment 4. [Figure 9] This is a diagram showing the configuration of the static elimination mechanism according to Embodiment 4. [Figure 10] This is a diagram showing the configuration of a laminator having a cleanliness monitoring device according to Embodiment 5. [Modes for carrying out the invention]

[0012] For clarity of explanation, the following descriptions and drawings have been omitted and simplified as appropriate. Furthermore, the same elements are denoted by the same reference numerals in each drawing, and redundant explanations have been omitted where necessary.

[0013] Embodiment 1 Figure 1 shows a configuration diagram illustrating the overview of the laminated molding system according to Embodiment 1. As shown in Figure 1, the laminated molding system according to Embodiment 1 includes a laminator 2, a flattening press device 3, and a flattening press device 4. The laminator 2, flattening press device 3, and flattening press device 4 are all laminated molding devices that form a molded product by applying pressure to a molded product, which has laminated material laminated onto a workpiece, using two pressing mechanisms arranged vertically opposite each other. In the laminated molding system according to Embodiment 1, the laminator 2, flattening press device 3, and flattening press device 4 are arranged in order. In the laminated molding system according to Embodiment 1, the laminator 2 forms a primary molded product by laminating material onto a workpiece, and the flattening press device 3 and flattening press device 4 form a secondary molded product in which the flatness of the laminated surface of the primary molded product is increased. By performing molding in this stepwise manner, the flatness of the surface of the laminated material of the finished product can be increased.

[0014] In performing the above lamination molding, the laminator 2, flattening press device 3, and flattening press device 4 have a pressurizing mechanism that transmits pressure to the molded product on which the laminated material is placed. This pressurizing mechanism is not particularly limited as long as it applies pressure to the molded product, but for example it may be a plate-shaped member (hot plate) that can be heated or cooled, or a flexible sheet that can be heated or cooled. This allows for the suitable production of primary and secondary molded products. In the example shown in Figure 1, the laminator 2, flattening press device 3, and flattening press device 4 are shown to have hot plates as the pressurizing mechanism. In Figure 1, the laminator 2 is shown to have an upper hot plate 21 and a lower hot plate 22, the flattening press device 3 is shown to have an upper hot plate 31 and a lower hot plate 32, and the flattening press device 4 is shown to have an upper hot plate 41 and a lower hot plate 42.

[0015] Further, in the laminate molding system according to Embodiment 1, a molded object in which a laminate material is placed on a to-be-laminated body on a carrier film is placed on the carrier film and moved from the laminator 2 to the flattening press apparatus 4. Therefore, in the laminate molding system according to Embodiment 1, the film unwinder 1 is disposed at the front stage of the laminator 2, and the film winder 5 is disposed at the rear stage of the flattening press apparatus 4. Then, the molded object is placed on the carrier film unwound by the film unwinder 1, and the carrier film is wound up by the film winder 5, thereby moving the molded object from the laminator 2 to the flattening press apparatus 4. Further, in the example shown in FIG. 1, a laminate molding system is illustrated in which the molded object is sandwiched between two vertically arranged carrier films and moved. Further, in the example shown in FIG. 1, an example is illustrated in which the film unwinder 1 includes an upper carrier film supply roll 11 and a lower carrier film supply roll 12 that are supply sources of the carrier films. Furthermore, FIG. 1 illustrates an example in which the film winder 5 includes an upper carrier film take-up roll 51 and a lower carrier film take-up roll 52 that take up the carrier films.

[0016] Note that in the present disclosure, for the sake of convenience, even when the molded object in which the laminate material is placed on the to-be-laminated body is pressurized by the laminator 2, this may be referred to as pressurizing the molded object in which the laminate material is laminated on the to-be-laminated body in some cases.

[0017] The laminate molding system according to Embodiment 1 is characterized in that a fan is provided on the top surface of each apparatus. This fan supplies a downward airflow that flows downward from the top surface of the housing of each apparatus. In the example shown in FIG. 1, an example is illustrated in which the film unwinder 1 is provided with a fan 10, the laminator 2 is provided with a fan 20, the flattening press apparatus 3 is provided with a fan 30, the flattening press apparatus 4 is provided with a fan 40, and the film winder 5 is provided with a fan 50. However, the fan only needs to be provided in at least one of the film unwinder 1, the laminator 2, the flattening press apparatus 3, the flattening press apparatus 4, and the film winder 5.

[0018] As described above, the fan supplies downward airflow into the housing of each device, thereby expelling foreign matter from the housing downwards. Therefore, in the laminated molding system according to Embodiment 1 shown in Figure 1, an exhaust space is provided at the bottom of each device. In other words, in the example shown in Figure 1, in the laminated molding system according to Embodiment 1, an exhaust hole or space is provided on the bottom surface of the housing of each device. Foreign matter refers to minute contaminants (impurities) that can be confirmed by observation with the naked eye or a microscope, or by measurement means such as a particle counter, and its shape, size, and material are not particularly limited. Foreign matter may be, for example, fine particles of resin, metal, or ceramics. Foreign matter may also be, for example, tiny organic matter such as chemical fibers or pollen.

[0019] Furthermore, fans are highly effective in preventing foreign matter from accumulating on the upper part of the casing due to the upward airflow generated by the air heated by heat-generating elements such as heat plates and motors. Therefore, the following description will explain a lamination molding apparatus that uses a heat plate as a pressurizing mechanism. In addition, while lamination molding apparatuses, including laminator 2, flattening press device 3, and flattening press device 4, all have common problems caused by foreign matter, the following description will explain the configuration and effect of the fan using laminator 2 as an example.

[0020] Figure 2 shows a configuration diagram of the laminator 2 according to Embodiment 1. As shown in Figure 2, the laminator 2 applies pressure to the product to be molded A1 using an upper heating plate 21 and a lower heating plate 22. The product to be molded A1 is made by layering a laminated film A3, which will be the laminating material, onto a substrate material A2, which will be the laminated body.

[0021] The laminator 2 has a pressurizing section that transmits pressure to the upper heating plate 21 and the lower heating plate 22. In addition to the upper heating plate 21 and the lower heating plate 22, this pressurizing section includes heat insulating plates 23 and 24, a fixed platen 25, a movable platen 26, a tie bar 27, a base platen 28, and a drive unit 29. The configuration of the drive unit 29 is not particularly limited, but the drive unit 29 may include, for example, a drive unit 29a that generates hydraulic or pneumatic pressure, a cylinder 29b, and a ram 29c. Alternatively, the drive unit 29 may be configured by replacing the drive unit 29a with a servo motor, the cylinder 29b with a ball nut, and the ram 29c with a screw shaft. In the laminator 2 according to Embodiment 1, the upper heating plate 21 is attached to the surface of the fixed platen 25 facing the workpiece A1 via a heat insulating plate 23. Furthermore, in the laminator 2 according to Embodiment 1, the lower heating plate 22 is attached to the surface of the movable platen 26 facing the workpiece A1 via an insulating plate 24.

[0022] The laminator 2 consists of a base plate 28 and a fixed plate 25 connected by tie bars 27. The movable plate 26 has housing sections 26a at its four corners. Ball spline cylinders provided on the tie bars 27 are positioned to pass through the housing sections 26a. The movable plate 26 is supported by a ram 29c located on its underside. The cylinder 29b raises or lowers the movable plate 26 by pushing up or down the ram 29c based on instructions from the drive unit 29a. This allows the movable plate 26 to move closer to and further away from the fixed plate 25 in the pressurizing section, and increases the pressure applied to the molded product A1 as the movable plate 26 approaches the fixed plate 25. The drive unit 29a controls the force and speed at which the movable plate 26 is raised or lowered based on instructions from a control panel (not shown) to the cylinder 29b.

[0023] Furthermore, as shown in Figure 2, in the laminator 2 according to Embodiment 1, the pressurized section is enclosed by a housing. In the example shown in Figure 2, the housing consists of a top HOU1, a bottom HOU2, and side HOU3 and HOU4. Although not shown in Figure 2, the laminator 2 is assumed to have four sides of the pressurized section enclosed by side members. In the laminator 2 according to Embodiment 1, an exhaust hole is provided in the bottom HOU2. In addition, in the laminator 2 according to Embodiment 1, a fan 20 is mounted above the top HOU1.

[0024] The fan 20 may simply supply a downward airflow from outside to inside the housing, but more preferably, it supplies airflow taken in from the outside via a filter that removes foreign matter as a downward airflow into the housing. The type of filter is not particularly limited, but it is preferable that it be a HEPA (High Efficiency Particulate Air) filter or an ULPA (Ultra Low Penetration Air) filter in order to remove foreign matter of 1 μm or less. Here, a HEPA filter may be defined as a filter capable of capturing 99.97% or more of fine particles with a particle size of 0.3 μm or larger, and a ULPA filter may be defined as a filter capable of capturing 99.9995% or more of fine particles with a particle size of 0.15 μm or larger. The particulate matter collection performance of the filter may also be evaluated according to, for example, JIS B 9908 or ISO 16890. In this way, by providing a filter that removes fine particles, it is possible to prevent foreign matter from outside the housing from entering the housing.

[0025] Next, we will explain how the downward airflow supplied by the fan 20 flows within the housing. Here, we will explain the difference in airflow with and without the fan 20 using diagrams. Figure 3 shows a diagram illustrating the airflow in a laminator according to a comparative example without the fan 20. As shown in Figure 3, without the fan 20, the air heated by heat sources such as the upper heating plate 21, the lower heating plate 22, and the drive unit 29a flows upward as an upward airflow towards the top of the housing. As a result, foreign matter DST accumulates near the top surface of the housing. This accumulated foreign matter DST grows into large clumps that fall and adhere to the molded product A1 or the upper carrier film, causing a decrease in the flatness of the molded product.

[0026] Next, Figure 4 shows a diagram illustrating the airflow in the laminator 2 according to Embodiment 1. As shown in Figure 4, in the laminator 2 according to Embodiment 1, the air heated by heat sources such as the upper heating plate 21, the lower heating plate 22, and the drive unit 29a is pushed by the downward airflow supplied by the fan 20 and discharged from the bottom surface HOU 2. As a result, foreign matter inside the housing of the laminator 2 is discharged outside the housing, thus reducing the risk of foreign matter DST impairing the flatness of the molded product, as is the case with the laminator according to the comparative example in Figure 3.

[0027] Here, we will describe an example of the configuration of the fan 20 described above. Figure 5 shows an example of the configuration of the fan 20 according to Embodiment 1. As shown in Figure 5, the fan 20 has a fan housing 61, an intake port 62, an outlet port 63, a first filter 64, a second filter 65, a motor 66, fins 67, and a sealing part 68. The motor 66 and fins 67 are housed in the fan housing 61 of the fan 20. An outlet port 63 is provided at the lower part of the fan housing 61 (for example, inside the housing of the laminator 2) via the second filter 65. On the other hand, an intake port 62 is provided at the upper part of the fan housing 61 via the first filter 64. In the fan 20, the motor 66 rotates the fins 67 based on a control signal provided from a control unit (not shown), thereby sending the air sucked in from the intake port 62 to the outlet port 63.

[0028] In the example shown in Figure 5, filters are provided on both the intake port 62 side and the outlet port 63 side. While there are no particular restrictions on the location or number of filters, it is preferable to have filters on both the outlet port and intake port sides. The first filter 64 and the second filter 65 may be the same or different. To further miniaturize the motor 66, it is preferable that the first filter 64 has a relatively coarse mesh opening and the second filter 65 has a relatively fine mesh opening.

[0029] Furthermore, as shown in Figure 5, the rotation radius of the fin 67 (for example, the length from the axis of rotation to the tip of the fin 37) is preferably set such that the angle θ between the line Xt connecting the outer circumference of the circle that forms the rotation trajectory of the tip of the fin 67 and the corner of the upper edge of the fixed platen 25 and the perpendicular line Xv is in the range of 0 to 75 degrees, and more preferably set to 5 to 55 degrees. If the angle θ is too large, most of the downdraft airflow sent from the fan 20 will be blocked by the fixed platen, which may reduce the efficiency of improving the cleanliness inside the enclosure. On the other hand, if the angle θ is too small, there will be problems such as the size of the fan 20 becoming unnecessarily large or the number of fans becoming unnecessarily large. However, by appropriately setting the angle θ, it is possible to improve the cleanliness inside the enclosure and prevent the fan 20 from becoming excessively large.

[0030] As described above, the laminated molding system according to Embodiment 1 has a configuration in which a fan is provided on the top surface of each device to discharge foreign matter from inside the housing of each device. As a result, the laminated molding system according to Embodiment 1 can efficiently mold molded products with high flatness.

[0031] Furthermore, in lamination molding systems, a hot plate is sometimes used as a pressurizing mechanism in the lamination molding apparatus, and the rising airflow generated due to such a heat source as a hot plate can cause foreign matter to accumulate inside the housing. However, in the lamination molding system according to Embodiment 1, the air heated by a fan installed on the top surface is discharged to the lower side where the exhaust port is located, so the installation of a fan on each device having a housing that contains a heat source is particularly effective in preventing a decrease in flatness caused by foreign matter.

[0032] Furthermore, the laminated molding system may be installed in a cleanroom. In a cleanroom, foreign matter is constantly expelled from the room by a downward airflow generally moving from the ceiling to the floor. Therefore, by supplying downward airflow into the enclosure in a direction that does not go against the airflow in the cleanroom, as in the laminated molding system according to Embodiment 1, it is possible to efficiently expel foreign matter from inside the enclosure while suppressing the fan output.

[0033] Furthermore, in a laminated molding system, fans may be provided in each device to supply air into the enclosure from the outside, thereby maintaining a positive pressure state where the air pressure inside the enclosure is higher than the air pressure outside the enclosure. By maintaining positive pressure inside the enclosure in this way, foreign matter can be expelled from the enclosure while further suppressing the inflow of foreign matter from the outside.

[0034] Embodiment 2 Embodiment 2 describes a laminator 2a having a different configuration of the pressurizing section of the laminator 2 according to Embodiment 1. In the description of Embodiment 2, components that are the same as those in Embodiment 1 are denoted by the same reference numerals as in Embodiment 1 and their descriptions are omitted.

[0035] Figure 6 shows a diagram illustrating the airflow in the laminator 2a according to Embodiment 2. As shown in Figure 6, in the laminator 2a, the fixed platen 25 has an inclined end surface 25a with a tapered shape where the end is lower than the top surface. In this way, by providing an inclined end surface 25a at the end of the surface facing the fan 20 in the pressurizing section, the downward airflow supplied from the fan 20 can be directed towards the bottom surface HOU2 without reducing its flow velocity.

[0036] As described above, in the laminator 2a according to Embodiment 2, a sloping end surface 25a having a tapered shape where the end is lower than the top surface is provided on the fixed platen 25. The angle of the tapered shape is not particularly limited, but it is preferably in the range of 5 to 75 degrees with respect to the horizontal plane. In this way, the downward airflow supplied from the fan 20 can be directed towards the bottom surface HOU2 without reducing the flow velocity. This makes it possible to more effectively discharge foreign matter inside the housing to the outside of the housing.

[0037] Embodiment 3 Embodiment 3 describes a laminator 2b having a different configuration of the side surfaces HOU3 and HOU4 of the laminator 2 according to Embodiment 1. In the description of Embodiment 3, components that are the same as those in Embodiment 1 are denoted by the same reference numerals as in Embodiment 1 and their descriptions are omitted.

[0038] Figure 7 shows a diagram illustrating the airflow in the laminator 2b according to Embodiment 3. As shown in Figure 7, in Embodiment 3, the laminator 2b has louvers LOU on its side surfaces HOU3 and HOU4, which serve as exhaust ports for discharging air from inside the enclosure. As shown in Figure 7, in the laminator 2b according to Embodiment 3, the flow of the downward airflow supplied from the fan 20 is adjusted, and the exhaust airflow generated due to heat sources such as the upper heating plate 21 is discharged from the louvers LOU provided on the side surfaces.

[0039] As described above, in the laminator 2b according to Embodiment 3, the flow of the downward airflow supplied from the fan 20 can be adjusted by providing louvers LOU on the sides HOU3 and HOU4. This allows foreign matter inside the enclosure to be discharged more effectively to the outside of the enclosure.

[0040] Embodiment 4 Embodiment 4 describes a laminator 2c, which is another form of the laminator 2 according to Embodiment 1. Figure 8 shows a configuration diagram of the laminator 2c according to Embodiment 4. The product to be molded is transported by a carrier film, but since the carrier film is a resin film such as polyethylene terephthalate (PET), static electricity is easily generated, and dust inside the housing is easily attracted to the carrier film and the product to be laminated. As a result, the cleanliness of the product to be laminated may decrease during molding.

[0041] Therefore, as shown in Figure 8, the laminated molding system according to Embodiment 4 differs from the above-described embodiment in that it includes a static elimination mechanism 70 in addition to the fan 20. In the description of Embodiment 4, components that are the same as those described in Embodiment 1 are denoted by the same reference numerals as in Embodiment 1 and their descriptions are omitted.

[0042] The main components of the static elimination mechanism 70 will be explained with reference to Figure 9. The static elimination mechanism 70 includes an intake port 71 that receives the clean airflow sent from the fan 20, an ion generator 73 that generates ions 72 for static elimination, an outlet port 74 that sends the ions 72 into the housing along with the airflow, and a sealing section 75 that airtightly connects the fan 20 side and the housing side, respectively.

[0043] The number of ions generated by the ion generator 73 decreases over time. Therefore, a faster airflow velocity from the fan 20 is preferable. However, if the airflow velocity is excessively high, the airflow inside the enclosure may become turbulent, potentially hindering the operation of the lamination molding system. Therefore, the airflow from the fan 20 should have a velocity of 0.1 to 1.5 meters per second (m / sec) and an airflow volume of 0.5 to 25 cubic meters per minute (m³). 3Preferably, the wind speed is in the range of 0.3 to 1.0 meters per second (m / sec) and the air volume is 5 to 20 cubic meters per minute (m³). 3 It is even more preferable that the values ​​be within the range of ( / min). Furthermore, it is preferable to use the average values ​​of the airflow and wind speed measured over a 10-minute period.

[0044] The method by which the ion generator 73 generates ions is not particularly limited, and for example, a method of applying an electric current to an electrode needle (corona discharge method) or a method of irradiating the air with electromagnetic waves such as X-rays can be used. This generates ions in the air, and fine particles and carrier films can be efficiently discharged. When applying an electric current to the electrode needle, it may be DC or AC, but it is preferable to use an AC pulsed current.

[0045] The sealing portion 75 is provided to airtightly connect the fan 20 to the intake port 71, the outlet port 74 to the housing. The means for making the connection airtight is not particularly limited, but it is preferable to use a packing that has elasticity and airtightness, such as resin or rubber. The sealing portion 75 may also be provided on the fan 20 or the housing.

[0046] As described above, in the laminated molding system according to Embodiment 4, the cleanliness inside the housing can be further improved by providing a static elimination mechanism 70 in addition to the fan 20.

[0047] Embodiment 5 Embodiment 5 describes a laminator that is a different form of the laminator 2 according to Embodiment 1. The cleanliness of the material to be laminated during molding can change over time due to maintenance of the lamination system, deterioration of the filter, etc. This can temporarily reduce the cleanliness of the material to be laminated during molding, which may hinder lamination molding in a clean environment. Therefore, the lamination molding system according to Embodiment 5 differs from the above-described embodiment in that the laminator 2 is equipped with a cleanliness monitoring device 80.

[0048] The main components of the cleanliness monitoring device 80 will be explained with reference to Figure 10. The cleanliness monitoring device 80 includes an intake unit 81 that takes in air from inside the housing of the laminator 2, a measurement unit 82 that measures the amount and size of fine particles in the intake air, an exhaust unit 83 that discharges the measured air, a communication unit 84 that transmits the measurement results from the measurement unit, and an output unit 85 that displays the transmitted measurement results.

[0049] Next, the principle of the cleanliness monitoring device 80 will be explained. Air inside the housing of the laminator 2 is taken in through the intake section 81 and sent to the measurement section 82. The measurement section 82 generates light scattering by irradiating the air with laser light. Such scattered light is detected by a light-receiving element provided in the measurement section 82 and converted into an electrical signal. This electrical signal is sent to the output section 85 via the communication section 84, and the output section 85 aggregates the magnitude of the electrical signal (voltage) as the size of the air particles and the number of electrical signals as the number of air particles, and displays it, for example, as a waveform over time. The measured air is discharged from the discharge section 83. Note that the intake and discharge of air inside the housing may be performed using a pump.

[0050] The output unit 85 may issue an alarm, such as by sounding an alarm or illuminating a rotating light, if particulate matter exceeding a predetermined threshold in size or quantity is detected. If an alarm is issued, the filter should be replaced or otherwise modified.

[0051] As described above, the laminated molding system according to Embodiment 5 can be made even cleaner inside the housing by providing a cleanliness monitoring device 80.

[0052] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. [Explanation of symbols]
