The moving device 12 may include an arm of a vertical robot, an arm of a SCARA robot, an arm of a parallel link robot, and an arm of a Cartesian robot.
[0104] The conveying device 10 receives the object 30 from a processing device 40 that processes the object 30. An example of the processing device 40 is a briquetting machine. The briquetting machine may be a molding machine, a compressor, or a solidifying machine. The processing device 40 processes the material to manufacture the object 30. The processing device 40, for example, applies pressure to the material to manufacture the object 30, which is a molded body. The shape and size of the material are not limited. The material is, for example, a metallic material. The metallic material is, for example, a metal piece. The metal piece may be, for example, a metal slice, a metal fragment, a metal chip, metal shavings, or metal powder. The pressure that the processing device 40 applies to the material is not limited, but for example, it may be 1 MPa or more, 100 MPa or more, or 200 MPa or more, and 2000 MPa or less, 1900 MPa or less, or 1800 MPa or less. Pressurization methods include uniaxial molding, cold isostatic pressing (CIP) molding, hot isostatic pressing (HIP) molding, and roller pressing.
[0105] The means by which each of the heating devices 20A, 20B, 20C... heats the object 30 are not particularly limited. The heating devices 20A, 20B, 20C... heat the object 30 by irradiating it with electromagnetic waves, for example. The heated object 30 is then sintered or melted and solidified, for example. If the object 30 contains volatile impurities, when the object 30 is heated, the impurities vaporize. This reduces the amount of impurities in the object 30, or removes the impurities from the object 30. If the object 30 contains oxides such as an oxide film, when the object 30 is heated, the oxides vaporize, or are reduced. This reduces the amount of oxides in the object 30, or removes the oxides from the object 30.
[0106] Electromagnetic waves are, for example, millimeter waves and microwaves. Millimeter waves are, for example, electromagnetic waves with frequencies from 30 GHz to 300 GHz. Microwaves are, for example, electromagnetic waves with frequencies from 300 MHz to 30 GHz. Each of the heating devices 20A, 20B, 20C, etc. may be equipped with a pressurizing section that applies pressure to the object 30. The pressurizing section may apply pressure to the object 30 at least one of the following times: before irradiating the object 30 with electromagnetic waves, while irradiating the object 30 with electromagnetic waves, and after irradiating the object 30 with electromagnetic waves.
[0107] Each heating device 20A, 20B, 20C... comprises a chamber and doors 21A, 21B, 21C... provided in the chamber. When an object 30 is placed inside the chamber, the doors 21A, 21B, 21C... are opened. When the object 30 is heated inside the chamber, the doors 21A, 21B, 21C... are closed. When the object 30 is removed from the chamber, the doors 21A, 21B, 21C... are opened.
[0108] For example, heating devices 20A, 20B, 20C, etc., have the same configuration. The configuration of heating device 20A will be described below. Heating device 20A includes, for example, a chamber 22A, an electromagnetic wave irradiation device 50A that irradiates electromagnetic waves into the chamber 22A, and a stage 23A provided in the chamber 22A for placing the object 30. The chamber 22A is provided with a window 61A for allowing electromagnetic waves emitted from the electromagnetic wave irradiation device 50A to pass through. Heating device 20A may also include a drive device 24A configured to rotate the stage 23A. By rotating the stage 23A, it is possible to irradiate the object 30 with electromagnetic waves uniformly. A promoter 25A that promotes heating of the object 30 may be placed on the stage 23A, and the object 30 may be placed on the stage 23A via the promoter 25A.
[0109] The heating device 20A may include a promoter 26A that contacts the upper surface of the object 30, as shown in Figure 9. The promoter 26A is configured to be movable up and down within the chamber 22A. The promoter 26A is connected, for example, to a shaft 27A. When the stage 23A rotates, the promoter 26A rotates passively via the frictional force between the upper surface of the stage 23A and the lower surface of the promoter 25A, the frictional force between the upper surface of the promoter 25A and the lower surface of the object 30, and the frictional force between the upper surface of the object 30 and the lower surface of the promoter 26A.
[0110] The promoters 25A and 26A may contain an insulating material that has higher electromagnetic wave permeability than the object 30 and absorbs electromagnetic waves to a lower degree than the object 30. The insulating material has a melting point higher than the melting point of the object 30. Because the insulating material absorbs electromagnetic waves to a low degree, it generates less heat even when irradiated with electromagnetic waves, thus exhibiting an insulating effect. Furthermore, because the insulating material has a higher melting point than the object 30, its shape remains stable even when irradiated with electromagnetic waves. Therefore, even while the object 30 irradiated with electromagnetic waves is sintering or melting, the promoters 25A and 26A containing the insulating material can maintain their shape.
[0111] The insulating material may contain metal oxides or metalloid oxides. Examples of metal and metalloid oxides include, but are not limited to, aluminum oxide (Al₂O₃), silicon oxide (SiO₂), magnesium oxide (MgO), zirconium oxide (ZrO₂), and titanium oxide (TiO₂). For example, the melting point of aluminum oxide (Al₂O₃) is 2072°C. The melting point of silicon oxide (SiO₂) is 1710°C. The melting point of magnesium oxide (MgO) is 2852°C. The insulating material may also be a compound of these.
[0112] The promoters 25A and 26A may include an absorbing material that absorbs electromagnetic waves at a temperature range that is at least partially lower than the temperature range in which the object 30 absorbs electromagnetic waves. The absorbing material has a melting point higher than the melting point of the object 30. At least partially of the temperature range in which the absorbing material absorbs electromagnetic waves is lower than the temperature range in which the object 30 absorbs electromagnetic waves. If the object 30 contains a metal, the temperature range in which the object 30 absorbs electromagnetic waves is, for example, 300°C to 1200°C, 450°C to 1100°C, or 600°C to 800°C. The temperature range in which the absorbing material absorbs electromagnetic waves is, for example, 100°C to 1000°C, 250°C to 900°C, or 400°C to 600°C.
[0113] Preferably, at least a portion of the temperature range in which the absorbing material absorbs electromagnetic waves overlaps with the temperature range in which the object 30 absorbs electromagnetic waves. Since the absorbing material absorbs electromagnetic waves at a temperature range that is at least partially lower than the temperature range in which the object 30 absorbs electromagnetic waves, it generates heat faster than the object 30. Therefore, the absorbing material can heat the object 30 before it reaches the temperature range in which it absorbs electromagnetic waves. Consequently, if the promoters 25A and 26A contain the absorbing material, the temperature of the object 30 reaches the temperature range in which it absorbs electromagnetic waves more quickly, and the heating time of the object 30 can be shortened. In addition, since the absorbing material absorbs electromagnetic waves at a temperature range that is at least partially lower than the temperature range in which the object 30 absorbs electromagnetic waves, it is possible to suppress the promoters 25A and 26A from being heated more than necessary. Therefore, even while the object 30 irradiated with electromagnetic waves is sintering or melting, the promoters 25A and 26A containing the absorbing material can maintain their shape.
[0114] The absorbing material includes, for example, a carbon material. Examples of carbon materials include, but are not limited to, carbon black, amorphous carbon, graphite, silicon carbide, carbon resin, and metal carbides. The absorbing material may also include the object 30 to be sintered or melted solidified, which absorbs electromagnetic waves at a temperature range at least partially lower than the temperature range in which the object 30 absorbs electromagnetic waves, metal nitrides, metal oxides, and metal borides. The absorbing material may also be compounds of these materials. It is preferable that the absorbing material does not contain volatile components. By not containing volatile components, it is possible to avoid the absorption of electromagnetic waves by volatile components.
[0115] Promoters 25A and 26A may contain a reducing material that reduces the target substance 30. The reducing material has a melting point higher than the melting point of the target substance 30. Examples of reducing materials include carbon and silicon carbide. A carbon material used as an absorbent material can also function as a reducing material.
[0116] Promoters 25A and 26A may consist solely of insulating materials, solely of absorbent materials, solely of reducing materials, or a combination thereof. Furthermore, the properties and functions of insulating materials, absorbent materials, and reducing materials may overlap. For example, a carbon material can function as both an absorbent and a reducing material.
[0117] The heating device 20A includes, for example, an aerosol sensor 51A configured to detect aerosols in the chamber 22A. Aerosols are, for example, smoke and vapor. The smoke may be oil fumes. The vapor may be water vapor. Aerosols are generated, for example, when the object 30 is heated and the volatile substances contained in the object 30 vaporize. The aerosol sensor 51A measures the aerosols, for example, by irradiating light into the chamber 22A and measuring the amount of light transmitted. Alternatively, the aerosol sensor 51A measures the aerosols by irradiating light into the chamber 22A and measuring the scattering of light. When the aerosol sensor 51A detects aerosols of a predetermined concentration, and then no more aerosols are detected or the amount of aerosols falls below a predetermined amount, it can be considered that the vaporization of the volatile substances contained in the object 30 is complete and the sintering and solidification of the object 30 is complete. The predetermined amount of aerosols can be set based on the amount of volatile substances that the object 30 is allowed to contain. A predetermined amount of aerosol can be a predetermined concentration of aerosol.
[0118] The heating device 20A includes, for example, a fire sensor 52A configured to detect fire, flames, and sparks in the chamber 22A. Fire, flames, and sparks occur, for example, when the object 30 is overheated. The heating device 20A also includes, for example, temperature sensors 53A, 54A, and 55A configured to detect the temperature in the chamber 22A. The temperature sensors 53A, 54A, and 55A may be radiation thermometers. When the temperature sensors 53A, 54A, and 55A detect that the object 30 has reached a predetermined temperature, or when they detect that the object 30 has reached a predetermined temperature and a predetermined time has elapsed, the sintering and solidification of the object 30 can be considered complete.
[0119] The heating device 20A may include an atmosphere control device 56 for controlling the atmosphere inside the chamber 22A. The atmosphere control device 56 may, for example, create an inert gas atmosphere inside the chamber 22A. Examples of inert gases include argon (Ar) and helium (He). The atmosphere control device 56 may, for example, create a neutral gas atmosphere inside the chamber 22A. Examples of neutral gases include nitrogen (N2), dry hydrogen (H2), and ammonia (NH3). The atmosphere control device 56 may, for example, create a reducing gas atmosphere inside the chamber 22A. Examples of reducing gases include hydrogen (H2), carbon monoxide (CO), and hydrocarbon gases (CH4, C3H8, C4H8). 10 Examples include the following. By making the atmosphere inside the chamber 22A reducing, it is possible to reduce oxides that the object 30 may contain.
[0120] Next, using the flowcharts in Figures 10 and 11, we will explain how to control the transport device 10 and the multiple heating devices 20A, 20B, 20C, etc. according to the embodiment, how to operate the transport device 10 and the multiple heating devices 20A, 20B, 20C, etc., and how to manufacture a solid.
[0121] In step S101, the processing device 40 transmits a processing completion signal to the control system 100 indicating that the processing of the object 30 is complete. The processing completion signal acquisition unit 110 of the control system 100 receives the processing completion signal. In step S102, the receiving instruction unit 111 of the control system 100 transmits a receiving instruction signal to the transport device 10 instructing it to receive the object 30 from the processing device 40. The transport device 10 receives the receiving instruction signal. If the transport device 10 is not at the location of the processing device 40, the movement instruction unit 103 of the control system 100 instructs the transport device 10 to move to the location of the processing device 40. The location of the processing device 40 includes the vicinity of the processing device 40, for example, in front of the processing device 40. In step S103, the transport device 10 receives the object 30 from the processing device 40. The transport device 10 transmits a receiving signal to the control system 100 indicating that it has received the object 30. The receiving signal acquisition unit 101 of the control system 100 receives the receiving signal.
[0122] In step S104, the device selection unit 102 of the control system 100 transmits a status confirmation signal to each of the multiple heating devices 20A, 20B, 20C... to confirm whether they are in operation or idle. Each of the multiple heating devices 20A, 20B, 20C... receives the status confirmation signal. Each of the multiple heating devices 20A, 20B, 20C... transmits a status notification signal to the device selection unit 102 of the control system 100 to notify it whether it is in operation or idle. The device selection unit 102 of the control system 100 receives the status notification signal.
[0123] In step S105, the device selection unit 102 of the control system 100 selects an available heating device from among the multiple heating devices 20A, 20B, 20C... as the selected heating device. If there are multiple available heating devices, the device selection unit 102 of the control system 100 may select the available heating device that results in the shortest travel distance for the conveying device 10 as the selected heating device. Here, we will explain an example in which the device selection unit 102 of the control system 100 selects heating device 20A as the selected heating device.
[0124] In step S106, the movement instruction unit 103 of the control system 100 transmits a movement instruction signal to the transport device 10 to move to the position of the selected heating device. The transport device 10 receives the movement instruction signal. The transport device 10 moves to the position of the heating device 20A, which is the selected heating device. The position of the heating device 20A includes the vicinity of the heating device 20A, for example, in front of the heating device 20A. The transport device 10 transmits a standby signal to the control system 100 indicating that it is waiting at the position of the selected heating device. The standby signal acquisition unit 104 of the control system 100 receives the standby signal. In step S107, the loading instruction unit 105 of the control system 100 transmits an open door instruction signal to the selected heating device to open the door 21A. The selected heating device receives the open door instruction signal and opens the door 21A.
[0125] In step S108, the loading instruction unit 105 of the control system 100 transmits a loading instruction signal to the transport device 10, instructing it to load the object 30 into the selected heating device with the door 21A open. The transport device 10 receives the loading instruction signal and loads the object 30 into the selected heating device. The transport device 10 transmits a loading signal to the control system 100 indicating that the object 30 has been loaded into the selected heating device. The loading signal acquisition unit 106 of the control system 100 receives the loading signal.
[0126] While the processing device 40 is processing multiple objects 30, the loop from steps S101 to S108 may be repeated, and the multiple objects 30 may be sequentially loaded into available heating devices. The loop from steps S101 to S108 may be performed in parallel with steps S109 to S113, which will be described later. Therefore, after performing step S108, the process may proceed to step S109 in parallel with repeating the loop from steps S101 to S108.
[0127] In step S109, the heating instruction unit 107 of the control system 100 transmits a heating instruction signal to the selected heating device to instruct it to close the door 21A and heat the object 30. The selected heating device receives the heating instruction signal. The heating instruction unit 107 may also transmit heating conditions to the selected heating device based on the composition of the object 30. The heating conditions may be set based on, for example, the material of the object 30. The heating conditions may be set based on, for example, the melting point and sintering temperature of the material of the object 30. The heating conditions may be set based on, for example, the amount of impurities present in the object 30. The heating conditions may include atmospheric conditions inside the chamber of the selected heating device. The selected heating device closes the door 21A. In step S110, the selected heating device heats the object 30 inside. If the selected heating device has received heating conditions, it heats the object 30 according to the heating conditions. If the heating conditions include atmospheric conditions, the atmosphere control device 56 of the selected heating device controls the atmosphere inside the chamber of the selected heating device according to the atmospheric conditions.
[0128] If the fire sensor 52A of the selected heating device does not detect fire, flames, or sparks due to abnormal heating of the object 30 in step S111, the process proceeds to step S112. If the fire sensor 52A of the selected heating device detects fire, flames, or sparks due to abnormal heating of the object 30 in step S111, the process proceeds to step S201 to determine whether the number of times fire, flames, or sparks have been detected is greater than or equal to a predetermined number. If the number of times fire, flames, or sparks have been detected is greater than or equal to a predetermined number, the selected heating device terminates heating of the object 30. If the number of times fire, flames, or sparks have been detected is not greater than or equal to a predetermined number, the selected heating device temporarily suspends heating of the object 30 in step S202. The process then returns to step S110.
[0129] In step S112, if impurities are attached to the object 30, or if the object 30 contains impurities, heating causes the impurities to vaporize from the object 30, generating an aerosol. The aerosol sensor 51A of the selected heating device detects the aerosol, and if it subsequently stops detecting aerosols or if the amount of aerosol falls below a predetermined level, the process proceeds to step S113. If the aerosol sensor 51A of the selected heating device has never detected an aerosol, or if it continues to detect aerosols, the process returns to step S110, and the selected heating device continues heating the object 30. In step S113, the selected heating device terminates the heating and solidification of the object 30. The selected heating device transmits a heating completion signal to the control system 100 indicating that heating of the object 30 is complete. The heating completion signal acquisition unit 108 of the control system 100 receives the heating completion signal.
[0130] In step S114, the unloading instruction unit 109 of the control system 100 sends an open door instruction signal to the selected heating device to open the door 21A. The selected heating device receives the open door instruction signal and opens the door 21A. In step S115, the unloading instruction unit 109 of the control system 100 sends an unloading instruction signal to the transport device 10 to unload the object 30 from inside the selected heating device. The transport device 10 receives the unloading instruction signal and unloads the object 30 from the selected heating device with the door 21A open. If the transport device 10 is not at the location of the selected heating device, the movement instruction unit 103 of the control system 100 instructs the transport device 10 to move to the location of the selected heating device. Furthermore, if the conveying device 10 is performing the loop from step S101 to S108, the conveying device 10 may perform the loop from step S101 to S108 once, then temporarily interrupt the loop from step S101 to S108 and perform step S115.
[0131] In step S116, the discharge instruction unit 109 of the control system 100 sends a door-close instruction signal to the selected heating device to close the door 21A. The selected heating device receives the door-close instruction signal and closes the door 21A. In step S117, the container status confirmation unit 112 of the control system 100 sends a container status confirmation signal to confirm whether there is space in the container 60 to put the object 30. The container 60 receives the container status confirmation signal. If there is space to put the object 30, the container 60 sends a container status notification signal to the control system 100 indicating that there is space to put the object 30. The container status confirmation unit 112 of the control system 100 receives the container status notification signal.
[0132] In step S118, the movement instruction unit 103 of the control system 100 instructs the conveying device 10 to move the object 30, which has been removed from the selected heating device, to the container 60. The conveying device 10 moves to the position of the container 60. The position of the container 60 includes the vicinity of the container 60, for example, in front of the container 60. The conveying device 10 places the object 30 into the container 60.
[0133] The data acquisition system 200 according to the embodiment shown in Figure 12 includes a pre-heating object data acquisition unit 201 that collects data on the object 30 before it is heated by the heating devices 20A, 20B, 20C, etc. The data on the object 30 before heating includes, for example, the weight, shape, temperature, strength, raw material components, raw material particle size, components mixed in the raw material, raw material supplier, and raw material arrival date of the object 30 before heating.
[0134] The weight of the object 30 before heating is measured, for example, by a mass meter installed in the processing device 40, conveying device 10, heating devices 20A, 20B, 20C, etc., or nearby thereto, and transmitted to the pre-heating object data acquisition unit 201. An example of a mass meter is a load cell.
[0135] The shape of the object 30 before heating is measured by the processing device 40, the conveying device 10, the heating devices 20A, 20B, 20C, etc., or by a shape measuring machine located near them, and transmitted to the pre-heating object data acquisition unit 201. Examples of shape include height, width, and surface roughness. Examples of shape measuring machines include laser sensors and cameras.
[0136] The temperature of the object 30 before heating is measured by thermometers installed in the processing device 40, conveying device 10, heating devices 20A, 20B, 20C, etc., or in their vicinity, and transmitted to the pre-heating object data collection unit 201. Examples of thermometers include radiation thermometers and thermocouples.
[0137] The strength of the object 30 before heating is measured by a strength measuring instrument provided in the vicinity of the processing device 40, the conveying device 10, the heating devices 20A, 20B, 20C, etc., and transmitted to the pre-heating object data collection unit 201. An example of a strength measuring instrument is a torque sensor. For example, in a mechanism for gripping the object 30, if a ball screw is driven by a motor to clamp the object 30 in the gripping part, the rotational torque of the motor may be detected.
[0138] The data acquisition system 200 according to the embodiment includes a heating data acquisition unit 202 that collects heating data in heating devices 20A, 20B, 20C, etc. The heating data includes, for example, the arrangement of the object 30 inside the heating devices 20A, 20B, 20C, etc., the time change in the temperature of the object 30, the time change in the temperature of the door, the heating time, the intensity of electromagnetic waves, the time change in the components of the ambient gas, the time change in the concentration of the ambient gas, the time change in the components of the exhaust gas, the time change in the concentration of the exhaust gas, the time change in the concentration of the aerosol, whether or not ignition occurred, and the time of ignition.
[0139] The arrangement of the object 30 within the heating devices 20A, 20B, 20C, etc. is measured, for example, by position sensors provided in the heating devices 20A, 20B, 20C, etc., and transmitted to the heating data acquisition unit 202. An example of a position sensor is a laser sensor.
[0140] The time-dependent changes in the temperature of the object 30 inside the heating devices 20A, 20B, 20C, etc., the time-dependent changes in the temperature of the door, and the time-dependent changes in the temperature of the exhaust gas are measured, for example, by thermometers installed in the heating devices 20A, 20B, 20C, etc., and transmitted to the heating data acquisition unit 202. Examples of thermometers include radiation thermometers and thermocouples.
[0141] The heating time in the heating devices 20A, 20B, 20C, etc. is measured, for example, by an electromagnetic wave irradiation device provided in the heating devices 20A, 20B, 20C, etc., and transmitted to the heating data acquisition unit 202. The intensity of the electromagnetic waves in the heating devices 20A, 20B, 20C, etc. is measured, for example, by an electromagnetic wave detector provided in the heating devices 20A, 20B, 20C, etc., and transmitted to the heating data acquisition unit 202.
[0142] The time-dependent changes in the atmospheric gas components, atmospheric gas concentration, exhaust gas components, and exhaust gas concentration within the heating devices 20A, 20B, 20C, etc. are measured, for example, by gas sensors installed in the heating devices 20A, 20B, 20C, etc., and transmitted to the heating data acquisition unit 202.
[0143] The time-dependent change in aerosol concentration within the heating devices 20A, 20B, 20C, etc. is measured, for example, by aerosol sensors provided in the heating devices 20A, 20B, 20C, etc., and transmitted to the heating data acquisition unit 202.
[0144] The presence or absence of ignition within the heating devices 20A, 20B, 20C, etc., and the duration of ignition are measured, for example, by fire sensors installed in the heating devices 20A, 20B, 20C, etc., and transmitted to the heating data collection unit 202.
[0145] The data acquisition system 200 according to the embodiment includes a post-heating object data acquisition unit 203 that collects data on the object 30 after it has been heated by the heating devices 20A, 20B, 20C, etc. The data on the object 30 after heating includes, for example, the weight, shape, temperature, strength, and processing lot number of the object 30 after heating. A processing lot is, for example, a collection of multiple objects 30 that have been heated over a certain period of time. Alternatively, a processing lot may be a collection of a certain number of objects 30.
[0146] The weight of the object 30 after heating is measured, for example, by a mass meter installed in the conveying device 10, heating devices 20A, 20B, 20C, etc., container 60, or nearby thereto, and transmitted to the post-heating object data acquisition unit 203. An example of a mass meter is a load cell.
[0147] The shape of the object 30 after heating is measured by the conveying device 10, heating devices 20A, 20B, 20C, etc., container 60, or a shape measuring device installed near them, and transmitted to the post-heating object data acquisition unit 203.
