Description

Jet processing device and jet processing method

The invention relates to an injection processing device and an injection processing method.

It is widely known that the jet processing for surface treatment by jetting the gas-solid two-phase flow mixed with the abrasive material into the compressed air from the jet nozzle to the workpiece is processed. Jet processing is used to remove rust or roughness of castings, remove rust, remove coating film, and treat substrates. Furthermore, in recent years, it has also been used for applications requiring high processing accuracy such as deburring, chamfering, surface roughness adjustment, etching, and film removal of electronic parts or optical parts.

The jet processing capability is affected by the jet pressure of the gas-solid two-phase flow and the amount of abrasive contained in the gas-solid two-phase flow. In other words, in order to improve the machining accuracy, the content of the abrasive in the gas-solid two-phase flow must be kept constant during the jet machining.

Patent Document 1 describes a device for jetting abrasives. The device includes: a spray nozzle, which sprays abrasives; an abrasive supply tray, which forms a plurality of abrasive supply holes for filling or capturing abrasives; an abrasive supply pipe, which communicates with the spray nozzles and abrasive supply holes; compression An air supply source, which communicates with the polishing material supply pipe and supplies compressed air; a duct, which introduces ejected air; and a transmission and reception pipe, which communicates with the duct and the polishing material supply pipe. The polishing material supply hole is a groove in which the circumferential surface of the polishing material supply disk is continuous in the circumferential direction, and a plurality of grooves are formed parallel to the center axis direction. The polishing material is flown from the polishing material supply hole by the air ejected from the duct and the transceiver tube, and is supplied to the polishing material supply tube. The abrasive material is pressure-fed from the abrasive material supply pipe to the spray nozzle by compressed air supplied from the compressed air supply source.

[Problems to be solved by the invention]

In the device described in Patent Document 1, the higher the injection pressure of the gas-solid two-phase flow injected from the injection nozzle, the higher the injection processing capability. The injection pressure of the injection nozzle is the difference between the pressure of the compressed air and the pressure of the injected air. Therefore, to increase the injection pressure, the pressure of the injected air must be kept small. However, when the pressure of the ejected air is suppressed to be small, the polishing material may remain in the polishing material supply hole, so that a fixed amount of polishing material may not be supplied to the injection nozzle.

The invention provides a jet processing device and a jet processing method that can spray quantitative abrasive materials. [Technical means to solve the problem]

The jet processing device of the present invention includes a nozzle, a storage section, a roller, a driving section, a filling section, a take-out section, and a supply pipe. The nozzle sprays the abrasive with compressed air. The storage unit stores the abrasives inside. The roller has a cylindrical shape, a groove-shaped concave portion is provided on the circumferential surface, and a rotation axis extending in the direction of the central axis is provided. The driving section rotates the roller around the rotation axis. The filling portion is arranged adjacent to the roller, and fills the abrasive material stored in the storage portion into the opposing concave portion. The take-out part is arranged adjacent to the roller in the downstream of the rotation direction of the roller more than the filling part, and the abrasive material is taken out from the opposite concave part by the air flow generated in the direction parallel to the extending direction of the concave part. The supply pipe supplies the abrasives taken out by the take-out section to the nozzle.

According to this jet processing apparatus, the abrasive material moves from the storage section to the filling section. The abrasive material is filled into the concave portion of the roller at the filling portion. The abrasive material filled into the concave portion is moved to the take-out portion by rotating the roller around the rotation axis with the driving portion. At the take-out part, an air flow is generated in a direction parallel to the extending direction of the concave part, so the abrasive is taken out from the concave part. The removed abrasive material is supplied to the nozzle from the extraction portion through the supply pipe by the air flow. In the take-out part, since the extending direction of the concave part coincides with the generating direction of the air flow, there is no need to force the abrasive to fly. Furthermore, the pressure of the air that generates air flow directly acts on the abrasive. Therefore, the abrasive can be taken out of the recessed portion at a lower pressure than when the abrasive is taken out by flying. By this, compared with the case where the abrasive is lifted up and taken out, the take-out portion can suppress the residual amount of the abrasive filled in the concave portion. Thus, the jet processing device of the present invention can jet a certain amount of abrasive material.

In the injection processing apparatus of one embodiment, the take-out portion may have a pipe extending in a direction parallel to the extending direction of the concave portion. Furthermore, a flow path that circulates the airflow that takes out the abrasive and transfers to the supply pipe may be formed by the concave portion facing the takeout portion and the inner wall of the pipe. Since the pipe of the take-out portion extends in a direction parallel to the extending direction of the recess, the flow path is formed by the pipe and the opposing recess. The abrasive material is taken out of the recess by generating air flow in the flow path. The extending direction of the concave portion in the flow path, the direction of generation of the air flow, and the extending direction of the pipeline are the same, so the abrasive material taken out from the concave portion is stably supplied from the concave portion to the supply piping without scattering. As a result, a fixed amount of abrasive can be supplied to the supply pipe from the recess.

In the jet processing apparatus of one embodiment, the concave portion is a groove of the roller extending in the direction of the central axis, and both ends may be open ends. In this case, the openings at both ends of the concave portion can suppress the obstruction and dispersion of the airflow toward the nozzle, so that the abrasive can be efficiently supplied to the nozzle. Thus, the jet processing device of the present invention can jet a certain amount of abrasive material.

The jet processing apparatus of one embodiment may further include an auxiliary compressed air supply unit connected to the supply piping and supplying auxiliary compressed air having a lower pressure than the air flow. In this case, the pressure of the air in the airflow is determined by the difference between the pressure of the air that generates the airflow and the auxiliary compressed air. By supplying auxiliary compressed air from the auxiliary compressed air supply section, it is possible to suppress the air that generates airflow in the take-out section from becoming high pressure. With this, it is possible to prevent the abrasive material from being taken into the supply pipe regardless of the rotation of the roller, and it is possible to stably supply the abrasive material to the nozzle.

The injection processing apparatus of an embodiment may further include a compressed air supply unit connected to the storage unit and the take-out unit, and supplying compressed air for pressurization to the storage unit and the take-out unit when the nozzle sprays the abrasive. Furthermore, the storage portion may be sealable. Furthermore, the inside of the storage portion may be pressurized by the compressed air for pressurization supplied from the compressed air supply portion to the storage portion. Moreover, the compressed air supplied from the compressed air supply unit to the take-out unit may generate airflow. In this case, the compressed compressed air supplied from the compressed air supply part to the storage part enables the sealed storage part to be pressurized, thereby filling the concave part tightly through the filling part, so each concave part can be The difference in the amount of abrasive materials is suppressed to be small. In addition, the compressed air for pressurization is supplied from the compressed air supply unit to the take-out unit, and an air flow is generated, so that the abrasive can be taken out from the concave part by extrusion. Thereby, the residual amount of the abrasive material filled in the concave portion can be suppressed.

Another aspect of the present invention, that is, the blast processing method is performed by a blast processing device, and includes: (1) Filling step, which fills the groove-shaped concave portion provided on the circumferential surface of the rotating cylindrical roller with abrasive material; (2) Moving step, which rotates the roller to move the concave portion from the position filled with abrasive material to the downstream of the rotation direction of the roller; (3) The supplying step, which uses the air flow generated in the direction parallel to the extending direction of the concave portion to take out the abrasive material from the opposing concave portion and supply it to the nozzle; and (4) Spraying step, which sprays the abrasive with compressed air from the nozzle.

According to this jet processing method, in the filling step, the abrasive is filled into the concave portion provided on the circumferential surface of the roller. In the moving step, the abrasive material filled into the recessed portion is moved from the position filled with the abrasive material to the downstream of the rotation direction of the roller by the rotation of the roller. In the supplying step, the abrasive material is taken out from the recessed portion due to the airflow generated in a direction parallel to the extending direction of the recessed portion, and supplied to the nozzle. In the spraying step, the nozzle sprays the abrasive material supplied from the concave portion. In the moving step, the concave portions filled with abrasive materials are sequentially moved by the rotation of the rollers, so the abrasive materials are continuously taken out from the concave portions by the air flow. In the supplying step, the extending direction of the concave portion coincides with the generating direction of the air flow, so there is no need to force the abrasive to fly. Furthermore, the pressure of the air that generates air flow directly acts on the abrasive. Therefore, the abrasive can be taken out of the recessed portion at a lower pressure than when the abrasive is taken out by flying. By this, compared with the case where the abrasive is lifted up and taken out, the take-out portion can suppress the residual amount of the abrasive filled in the concave portion. Thus, the jet processing method of the present invention can jet a certain amount of abrasive material.

In the injection processing method of an embodiment, the moving step may also have a flow path forming step, which forms the flow path by the inner wall of the pipe extending in a direction parallel to the extending direction of the recess and the recess opposite to the pipe . In the flow path forming step, the pipeline extends in a direction parallel to the extending direction of the concave portion, so the flow path is formed by the pipeline and the opposed concave portion. By generating air flow in the flow path, the abrasive material is taken out from the concave portion. The extending direction of the concave portion in the flow path, the direction of generation of the air flow, and the extending direction of the pipeline are the same, so the abrasive material taken out from the concave portion is stably supplied from the concave portion to the supply piping without scattering. As a result, a fixed amount of abrasive can be supplied to the supply pipe from the recess.

In the jet processing method of one embodiment, the concave portion is a groove extending in the direction of the central axis of the roller, and both ends may be open ends. In this case, the openings at both ends of the concave portion suppress the obstruction and dispersion of the airflow toward the nozzle, so that the abrasive can be efficiently supplied to the nozzle. Thus, the jet processing method of the present invention can jet a certain amount of abrasive material.

In the injection processing method of one embodiment, the supply step further includes an auxiliary step, which supplies auxiliary compressed air having a lower pressure than the air flow when the abrasive is supplied to the nozzle. In this case, the pressure of the air in the airflow is determined by the difference between the pressure of the air that generates the airflow and the auxiliary compressed air. In the auxiliary step, by supplying auxiliary compressed air, the air generating the air flow can be suppressed from becoming high pressure. With this, it is possible to prevent the abrasive material from being taken into the pipeline regardless of the rotation of the roller, and it is possible to stably supply the abrasive material to the nozzle.

The jet processing method of an embodiment may be that the jet processing apparatus further includes a storage section that stores the abrasive material and can be sealed; in the filling step, the storage section is pressurized by supplying pressurized compressed air to the storage section In the supplying step, air flow is generated by supplying compressed air for pressurization to the recess. In this case, in the filling step, pressurized compressed air is used to pressurize the inside of the sealable storage portion to closely fill the concave portion, so that the difference in the amount of abrasive material for each concave portion can be suppressed. In addition, the compressed air for pressurization is supplied in the supplying step, and an air flow is generated, so that the abrasive can be taken out of the recessed portion by extrusion. Thereby, the residual amount of the abrasive material filled in the concave portion can be suppressed. [Effect of invention]

The size ratio of the drawings does not have to be consistent with the situation described. "Up", "Down", "Left", and "Right" are terms based on the state of the icon, and are used for convenience.

(Jet processing device) Fig. 1 is an overall cross-sectional view showing an injection processing apparatus of an embodiment. The jet processing apparatus 1 shown in FIG. 1 is an apparatus that jets a fixed amount of abrasive material 3 supplied from the abrasive material supply device 2. The blast processing apparatus 1 performs blast processing, which is one of cutting processing methods such as cutting, groove processing, and hole processing, by spraying the abrasive material 3 on the workpiece 4. The blasting method of the blasting apparatus 1 is, for example, direct pressure blasting. The abrasive 3 is, for example, alumina powder, pig iron sand, mold sand, or the like. The workpiece 4 is, for example, hard and brittle materials such as ceramic materials and glass materials, and hard-to-cut materials such as CFRP (Carbon Fiber Reinforced Plastics) materials.

The jet processing device 1 may include an abrasive material supply device 2, a processing unit 5, a recovery unit 6, and a dust collection unit 7. The jet processing apparatus 1 jets the mixed fluid of the abrasive 3 and compressed air supplied through the abrasive supplying apparatus 2 at the processing section 5 toward the workpiece 4 to perform jet processing. The jet processing apparatus 1 collects and reuses the abrasive 3 used in the processing section 5. When the processing section 5 performs the blast processing of the workpiece 4, a powder or granular body 8 including the abrasive 3 used is generated. The powder and granules 8 include, for example, reusable grinding material 3, crushed and unusable grinding material 3, and cutting powder produced by cutting off the workpiece 4 by spraying the grinding material 3. The jet processing device 1 collects the powder and granules 8 from the processing unit 5 to the collection unit 6. The jet processing device 1 sends the reusable abrasive material 3 in the powder and granular body 8 from the recovery section 6 to the abrasive material supply device 2. The blast processing apparatus 1 supplies the reusable abrasive 3 to the processing section 5 via the abrasive supply device 2 and sprays it. The jet processing device 1 sends the abrasive material 3 and the cutting powder that can no longer be used from the recovery section 6 to the dust collection section 7 to accumulate it.

The processing chamber 509 is partitioned into the upper cover 506 and the lower cover 507, for example.

The upper cover 506 has, for example, a box shape with an open bottom. The upper cover 506 is one of the components forming the processing chamber 509. The upper cover 506 may include an observation window 510 and a passing plate 511. The observation window 510 is provided above the upper cover 506. The observation window 510 is formed, for example, in an opening communicating with the processing chamber 509, and a plate member made of quartz glass or the like is embedded in the window frame member. Through the observation window 510, the inside of the processing chamber 509 can be observed. The board 511 is disposed on the lower end surface of the upper cover 506. The passage plate 511 is provided with a plurality of openings through which the powder and granules 8 can pass toward the bottom.

The lower cover 507 has, for example, an inverted quadrangular pyramid shape with an upper end surface opened. The lower cover 507 is one of the members forming the processing chamber 509. On the upper end of the lower cover 507, there is a frame for the lower end of the upper cover 506 to be embedded. The upper cover 506 can be rotatably connected to one side of the frame, for example. The processing chamber 509 can be opened and closed by rotating the upper cover 506. In addition, to the lower end of the lower cover 507, a recovery duct 601 described below is connected. The processing chamber 509 and the classifying section 602 described below are connected via a recovery duct 601 described below.

The outer frame 508 has, for example, a box shape whose upper and lower end surfaces are open. The outer frame 508 has a processing section base 512 with respect to the installation surface of the blast processing apparatus 1. The outer frame 508 is erected on the base 512 of the processing section. The outer frame 508 supports the lower cover 507 so as to be away from the processing unit base 512. The upper end of the outer frame 508 is fixed to the frame of the upper end of the lower cover 507, for example.

The nozzle 502 is arranged, for example, in the upper part of the processing chamber 509 of the upper cover 506. The nozzle 502 sprays the abrasive 3 together with compressed air. The nozzle 502 can eject the abrasive 3 as a mixed fluid (gas-solid two-phase flow) together with the compressed air 75 for taking out described below and the auxiliary compressed air 83 described below. The nozzle 502 is, for example, a spray nozzle for direct-pressure blasting.

The processing table 503 is a table on which the workpiece 4 is placed. The processing table 503 is disposed in the processing chamber 509 of the upper cover 506. The processing table 503 is mounted on the conveyor driving section 505 in a direction in which the abrasive material 3 of the nozzle 502 is sprayed in a direction orthogonal to the extending direction of the nozzle 502. The surface of the processing table 503 on which the object to be processed 4 is placed may also be the surface to which the object to be processed 4 is adsorbed.

The nozzle driving section 504 is disposed on the upper surface of the outer side of the upper cover 506. The nozzle driving unit 504 is connected to the nozzle 502. The nozzle driving unit 504 moves the nozzle 502 such that the workpiece 4 relatively moves with respect to the ejection area of the nozzle 502 to eject the abrasive 3. The conveyor driving section 505 is placed on the upper surface of the passing plate 511. The conveyor driving section 505 is connected to the lower surface of the processing table 503. The conveyor driving unit 505 moves the processing table 503 so that the workpiece 4 moves relative to the spray area of the nozzle 502 to spray the abrasive 3. The conveyor drive unit 505 is, for example, a moving mechanism such as an X-Y stage. At least one of the nozzle driving unit 504 and the conveyor driving unit 505 can relatively move the workpiece. The scanning of the nozzle driving unit 504 and the conveyor driving unit 505 can be adjusted according to the size, shape, etc. of the workpiece 4.

(Recycling Department) The recovery part 6 recovers the powder and granules 8 produced by the workpiece 4 in the processing part 5 during the blasting process. The recovery part 6 conveys the abrasive 3 reusable in the powder and granular body 8 to the tank 11 described below. The recovery unit 6 conveys the abrasive 3 that cannot be reused in the powder or granular body 8 and the cutting powder generated by peeling of the workpiece 4 to the dust collector 702 described below. The recovery unit 6 has a recovery duct 601 and a classification unit 602. The recovery duct 601 is a pipe connected to the lower cover 507 at one end and to the classifying section 602 at the other end. The recovery duct 601 transports the powder and granules 8 from the lower cover 507 to the classifying section 602 by the airflow generated by the dust collector 702 described below.

The upper part of the classifying part 602 communicates with the dust collecting duct 701 described below. The classification unit 602 communicates with the tank 11 described below via a supply valve 12 described below. The classifying unit 602 has a mortar-shaped hollow structure, for example. The classifying unit 602 classifies the powder and granules 8 transported from the recovery duct 601 into reusable abrasives 3, reusable abrasives 3, and cutting powders. The classifying unit 602 is, for example, a cyclone.

The powder and granules 8 circulate in the classifying section 602, for example. Among the powders and granules 8, the reusable abrasive 3 is heavier than the reusable abrasive 3 and the cutting powder. The abrasive material 3 that can be reused as relatively heavier particles is dropped by gravity to the vicinity of the following supply valve 12 in the classifying section 602 and accumulates when the rotation speed is decelerated. The compressed air 74 for the storage section described below does not flow into the tank 11 described below, and the supply valve 12 described below is opened. When the tank 11 and the classification section 602 communicate with each other, the accumulation in the classification section 602 is accumulated in the supply valve 12 described below The reusable abrasive material 3 in the vicinity is sent to the following tank 11 of the abrasive material supply device 2. The abrasive 3 and the cutting powder, which are relatively light particles and can no longer be used, are transported to the following dust collecting duct 701 connected to the upper part of the classifying section 602.

(Dust collection department) The dust collecting part 7 accumulates the abrasive material 3 and the cutting powder that are no longer usable by the collecting part 6. The dust collecting part 7 has a dust collecting duct 701 and a dust collecting machine 702. The dust collection duct 701 is a pipe connected to the classification part 602 at one end and to the dust collector 702 at the other end. The dust collecting duct 701 conveys the unusable abrasive 3 and cutting powder to the dust collecting machine 702 from the classifying unit 602.

The dust collector 702 accumulates the abrasive material 3 and the cutting powder that are no longer usable and transported from the dust collection duct 701. The dust collector 702 has an attraction generating source and a filter (not shown). An airflow is generated toward the dust collector 702 by actuating the attraction generating source in the processing chamber 509, the recovery duct 601, the classification section 602, and the dust collection duct 701 connected to the dust collector 702. By the action of the attraction generating source, the unusable abrasive material 3 and cutting powder conveyed from the dust collection duct 701 are attracted into the dust collector 702 together with the air. In the dust collector 702, the filter is disposed in the path of the dust collection duct 701 and the attraction generating source. The filter captures the abrasive 3 and cutting powder that can no longer be used. The filter only moves the air to the source of attraction. The captured abrasive 3 and cutting powder that can no longer be used can be recovered by removing the filter.

The tank 11 is connected to the supply valve 12 and the classifying unit 602 on the upper surface of the box. The can 11 is connected to the filling portion 20 at the lower end of the inverted quadrangular pyramidal portion. The pot 11 lowers the stored abrasive 3 from the box portion below the inverted quadrangular frustum portion, and supplies it to the connected filling portion 20. The tank 11 can be sealed.

The supply valve 12 is connected to the upper surface of the tank portion of the tank 11. The supply valve 12 is a valve that connects or blocks the tank 11 and the classifying section 602. The supply valve 12 is, for example, a relief valve or a triangular valve that is driven by an air cylinder or the like to make the conical valve up and down. The supply valve 12 is closed when the tank 11 is further pressurized at a specific pressure. In this case, the can 11 is sealed. The supply valve 12 connects or blocks the tank 11 and the classifying section 602 by opening and closing, and controls the supply of the polishing material 3 from the classifying section 602 to the tank 11. The vibrator 13 is connected to the outer surface of the tank 11. The vibrator 13 is connected to, for example, the outer surface of the inverted quadrangular truncated cone portion of the tank 11. The vibrator 13 vibrates the tank 11. The vibrator 13 suppresses uneven distribution or residue of the polishing material 3 in the tank 11 by vibration, and can smoothly supply the polishing material 3 to the lower filling portion 20.

The filling portion 20 is arranged adjacent to the roller 30, and fills the abrasive 31 stored in the tank 11 into the concave portion 31 on the roller 30 facing below. The filling section 20 has a filling tube 21. The filling cylinder 21 has a hollow structure, for example. The filling tube 21 has a can opening 22 at the upper end and a filling opening 23 at the lower end. The outer surface of the filling tube 21 is connected to the body 42 described below. The filling cylinder 21 is connected to the tank 11 at the tank opening 22. The filling opening 23 is arranged to face the recess 31 described below. The filling opening 23 is close to or in contact with the circumferential surface of the roller 30. The length of the filling opening 23 in the center axis direction of the roller 30 is equal to or greater than the length in the center axis direction of the circumferential surface of the roller 30. The length of the filling opening 23 in the direction orthogonal to the central axis of the roller 30 is equal to or greater than the circumferential length of the recess 31. That is, the filling opening 23 is arranged so as to cover the recess 31.

The roller 30 moves the abrasive 3 filled from the filling section 20 to the take-out section 50. The roller 30 has a cylindrical shape. The central axis of the roller 30 is the axis connecting the centers of the circles of the end surfaces facing each other. The roller 30 has a recess 31 and a rotating shaft 32. The recess 31 is provided in a groove shape on the circumferential surface of the roller 30. The recess 31 is a groove extending in the direction of the central axis, and both ends may be open ends. The cross-sectional shape of the recess 31 is, for example, a quadrangle. The circumferential surface of the roller 30 is close to or in contact with the filling opening 23 of the filling portion 20 so that the abrasive material 3 can be filled into the recess 31 from the filling portion 20. The rotating shaft 32 is an axis extending in the direction of the central axis of the center of the circle connecting the end surfaces facing each other. The roller 30 can rotate around the rotating shaft 32.

The driving unit 40 rotates the roller 30 around the rotation shaft 32. The driving unit 40 includes a rotating unit 41, a control unit (not shown), and a body 42. The rotating part 41 is connected to the rotating shaft 32 and the control part. The rotating part 41 rotates the roller 30 via the rotating shaft 32. The rotating section 41 is, for example, a motor. The control unit sets the rotation speed of the rotation unit 41. The control unit includes, for example, a computing device such as a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and HDD (Hard Disk Drive) , Hard disk drive) and other general-purpose computers such as memory devices and communication devices. The control unit may be, for example, a PLC (Programmable Logic Controller, programmable logic controller). The control unit may be a hardware that controls the entire jet processing device 1. The roller 30 rotates at a constant speed by the rotating portion 41 at the speed set by the control portion. By changing the rotation speed of the roller 30 by the control unit, the supply amount of the abrasive material 3 to the nozzle 502 per unit time can be changed, and the processing capability of the spray processing device 1 can be adjusted. The control unit may also control the nozzle driving unit 504 and the conveyor driving unit 505.

The body 42 accommodates at least a part of the filling part 20, the roller 30, the driving part 40, and the take-out part 50 inside. The body 42 is, for example, a hollow and sealed box-shaped container. The vibrator 13 may be further arranged outside the body 42. The main body 42 can suppress the outflow of the compressed air 75 for extraction supplied from the compressed air supply unit 70 described below to the outside.

The take-out section 50 is arranged adjacent to the roller 30, and takes out the abrasive 3 from the opposed concave section 31 using air flow. The take-out unit 50 conveys the abrasive 3 to the supply pipe 60. The extraction part 50 has a pipe 51. The pipe 51 is a pipe through which air flow can be ventilated inside. The cross-sectional area of the duct 51 in the ventilation direction is the same as or larger than the cross-sectional area in the width direction of the circumferential surface of the recess 31. The pipeline 51 is a pipeline extending in a direction parallel to the extending direction of the recess 31. The pipe 51 may be parallel to the circumferential surface of the roller 30. The pipe 51 is arranged adjacent to the roller 30 downstream of the filling portion 20 in the rotation direction of the roller 30. The pipe 51 is arranged at a position where the abrasive material 3 filled in the recess 31 can be prevented from falling naturally from the recess 31. The outer surface of the pipe 51 is connected to the body 42.

The pipe 51 is a tube having an opening 52, and a part of the opening 52 is opened so that a part of the circumferential surface of the roller 30 can be rotatably fitted. The pipe 51 is opposed to one or a plurality of recesses 31 by being rotatably fitted to the opening 52 by a part of the supply roller 30. The recess 31 and the pipe 51 are opposed to the opening 52, so the flow path 53 is formed by the recess 31 and the inner wall of the pipe 51. The flow path 53 refers to a section formed by the recess 31 and the inner wall of the pipe 51. The flow path 53 circulates air that takes out the abrasive 3 and transfers it to the supply pipe 60.

The supply pipe 60 supplies the abrasive 3 taken out by the taking-out unit 50 to the nozzle 502. The supply pipe 60 is a pipe that connects the pipeline 51 and the nozzle 502. In the supply pipe 60, the mixed fluid of the abrasive 3 and the air taken out from the recess 31 flows into the flow path 53.

The compressed air supply unit 70 is connected to the storage unit 10 and the extraction unit 50, and supplies compressed air for pressurization to the storage unit 10 and the extraction unit 50, respectively. The compressed air supply unit 70 may include a compressed air supply device 71 (refer to FIG. 1 ), a compressed air duct 72, and a pressurizing duct 73. The compressed air supply device 71 is a device that supplies compressed air for pressurization. The compressed air supply device 71 is, for example, a compressor. The compressed air duct 72 has one end connected to the compressed air supply device 71, and the other end of the compressed air duct 72 is branched into a pipeline 51 and a pressurizing duct 73. The pressurizing duct 73 communicates with the tank 11 and the compressed air supply device 71. The pressurizing duct 73 communicates with the tank 11 on the upper surface of the tank portion of the tank 11, for example. The compressed air for pressurization has the compressed air 74 for storage parts, and the compressed air 75 for extraction.

The compressed air supply device 71 can supply the compressed air 74 for the storage portion in the compressed compressed air to the compressed air duct 72 and the pressurized duct 73 when the abrasive 3 is sprayed from the nozzle 502. The compressed air 74 for the storage part flows into the tank 11 through the compressed air duct 72 and the pressurizing duct 73. The compressed air 74 for the storage portion flows into the tank 11 to pressurize the tank 11. The compressed air 74 in the storage section pressurizes the inside of the tank 11 to close the supply valve 12 to block the tank 11 and the classifying section 602. The abrasive 3 in the tank 11 after being pressurized with compressed air 74 by the storage section moves to the filling cylinder 21 communicating with the tank 11. The abrasive material 3 in the filling cylinder 21 is pressurized downward by compressed air 74 for the storage portion in the tank 11, and is tightly filled into each concave portion 31.

The compressed air supply device 71 can supply the compressed air 75 for taking out of the compressed air for pressurization to the compressed air duct 72 and the flow path 53 when the abrasive 3 is sprayed from the nozzle 502. The extracted compressed air 75 generates an air flow in a direction parallel to the extending direction of the recess 31. The airflow generated by the extracted compressed air 75 passes through the compressed air duct 72 and the flow path 53 and hits the abrasive 3 filled in the recess 31 in the flow path 53, thereby squeezing the abrasive 3 toward the supply pipe 60. The compressed air supply device 71 continuously supplies compressed air 75 for extraction as compressed air for pressurization, thereby supplying the abrasive 3 from the flow path 53 to the supply pipe 60.

The auxiliary compressed air supply unit 80 supplies compressed air to the supply pipe 60. The auxiliary compressed air supply unit 80 includes an auxiliary compressed air supply device 81 (see FIG. 1) and an auxiliary duct 82. The auxiliary compressed air supply device 81 is a device that supplies compressed air. The auxiliary compressed air supply device 81 is, for example, a compressor. The auxiliary compressed air supply device 81 communicates with the auxiliary duct 82. The auxiliary duct 82 communicates with the supply piping 60 and the auxiliary compressed air supply device 81. The auxiliary compressed air supply device 81 supplies the auxiliary compressed air 83 with a lower pressure than the compressed air 74 for storage or the compressed air 75 for extraction to the supply pipe 60 through the auxiliary duct 82. The auxiliary compressed air supply device 81 may control the supply amount of the auxiliary compressed air 83 according to the pressure of the extracted compressed air 75. The mixed fluid of the abrasive 3, the compressed air 75 for extraction, and the auxiliary compressed air 83 moves to the nozzle 502 through the supply pipe 60.

The pressure of the extracted compressed air 75 is determined by the difference between the compressed air 74 for the storage section and the auxiliary compressed air 83. When the differential pressure between the compressed air 74 for the storage section and the auxiliary compressed air 83 is small, the pressure of the compressed air 75 for extraction is small, so that the recess 31 cannot be sufficiently pressurized, and the abrasive 3 may remain. When the differential pressure between the compressed air 74 for the storage section and the auxiliary compressed air 83 is high, the polishing material 3 can be taken into the supply pipe 60 from the recessed section 31 regardless of the rotation of the roller 30, so that it is impossible to stably grind The material 3 may be supplied to the nozzle 502. In order to allow the compressed air 75 for extraction to stably supply the fixed amount of the abrasive 3 to the nozzle 502, the differential pressure between the compressed air 74 for the storage section and the auxiliary compressed air 83 may be set between 0.01 MPa and 0.1 MPa. Since the flow path 53 and the pressurizing duct 73 communicate with the compressed air duct 72, the pressure in the tank 11, the main body 42, and the take-out portion 50 becomes substantially the same.

(Steps of jet processing device) The blast processing steps performed by the blast processing apparatus 1 will be described. Fig. 4 is a flowchart showing the overall steps of the injection processing apparatus of the embodiment. In the dust collection process (S1), the dust collector 702 generates a flow of air that attracts the powder particles 8 and air toward the dust collector 702 inside the processing chamber 509, the recovery duct 601, the classification section 602, and the dust collection duct 701. The airflow generated by the operation of the dust collector 702 moves the powder and granules 8 generated in the processing chamber 509 to the processing chamber 509, the recovery duct 601, and the classifying section 602 in sequence. By the classification by the classification section 602, the reusable abrasive 3 is recovered to the tank 11, and the unreusable abrasive 3 and the cutting powder are recovered to the dust collector 702 through the dust collection duct 701.

Next, in the workpiece setting process (S2), the workpiece 4 is placed on the surface of the processing table 503 facing the nozzle 502 through the observation window 510. Next, in the adjustment process (S3), the distance between the nozzle 502 of the nozzle driving unit 504 and the workpiece 4 and the injection pressure of the abrasive 3 in the nozzle 502 are adjusted. In the adjustment process (S3), the scanning speed and trajectory of the workpiece 4 by the conveyor drive unit 505 are set. The adjustment process (S3) can be processed in the control unit.

Next, in the jet processing (S4), the abrasive 3 is supplied from the tank 11 to the nozzle 502 together with the compressed air 75 for extraction and the auxiliary compressed air 83. The workpiece 4 is sprayed by spraying the abrasive 3 from the nozzle 502 together with the compressed air 75 for extraction and the auxiliary compressed air 83 as a mixed fluid. Based on the scanning speed and trajectory set in the adjustment process (S3), the conveyor drive unit 505 moves the workpiece 4 and the processing table 503 on the conveyor drive unit 505 relative to the nozzle 502. The workpiece 4 is processed based on the trajectory set by the scan of the conveyor drive unit 505. When the set scanning and processing are completed, the mixed fluid of the abrasive 3 sprayed from the nozzle 502, the compressed air 75 for extraction, and the auxiliary compressed air 83 is stopped. Finally, in the workpiece recovery process (S5), the workpiece 4 is recovered from the surface of the processing table 503 through the observation window 510.

The detailed procedure of the abrasive material supply device 2 in the blast processing (S4) will be described. Fig. 5 is a flowchart of the blast processing. The abrasive 3 is stored in the tank 11 before the compressed air supply process (S11) in the storage unit is started. In the compressed air supply process for the storage section (S11), the compressed air 74 for the storage section is supplied from the compressed air supply device 71 through the compressed air duct 72 and the pressurizing duct 73 into the tank 11. Next, in the valve closing process (S12), the compressed air 74 for the storage part is supplied into the tank 11 to pressurize the inside of the tank 11, and the supply valve 12 on the upper part of the tank 11 is closed. With this, the can 11 is sealed. Next, in the filling part supply process (S13), the abrasive 3 is pressurized in the tank 11 by the compressed air 74 for the storage part, and moves to the filling cylinder 21. Next, in the abrasive filling process (S14), the abrasive 3 is filled into the recess 31 by the filling cylinder 21. The abrasive material 3 passes through the tank 11 and the filling cylinder 21 and is pressurized by the storage portion with compressed air 74 to thereby tightly fill each concave portion 31.

Next, in the turning process (S21), the roller 30 is rotated at the speed set by the control unit by the power of the driving unit 40. Next, in the flow path forming process (S22), the abrasive 3 filled into the recess 31 is moved from the position of the filling opening 23 to the position of the pipe 51 by the rotation of the roller 30 in the spinning process (S21),流流53。 53 is formed. In the flow path forming process (S22), the abrasive 3 filled in the recess 31 is supplied into the flow path 53.

Next, in the extraction compressed air supply process (S31), the extraction compressed air 75 is supplied from the compressed air supply device 71 through the compressed air duct 72 into the flow path 53. The extracted compressed air 75 generates an air flow in a direction parallel to the extending direction of the recess 31. The abrasive material 3 filled in the concave portion 31 is extruded into the pipe 51 by the air flow generated by the compressed air 75 taken out. The abrasive material 3 is supplied to the supply pipe 60 through the pipe 51 by the air flow generated by the compressed air 75 for extraction. Furthermore, in the compressed air supply process for the storage section (S11), the compressed air 74 for the storage section is supplied to the tank 11 by the supply of compressed air for pressurization, and the compressed air 75 for the extraction is supplied to the pipe 51 Therefore, there is no need to provide a compressed air supply process for taking out (S31).

Next, in the auxiliary compressed air supply process (S32), the auxiliary compressed air 83 is supplied from the auxiliary compressed air supply device 81 to the supply pipe 60. Next, in the nozzle supply process (S33), the abrasive 3 is supplied to the nozzle 502 through the supply pipe 60 together with the compressed air 75 for extraction and the auxiliary compressed air 83.

Finally, in the injection process (S41), the abrasive 3 is injected as a mixed fluid from the nozzle 502 together with the compressed air for extraction 75 and the auxiliary compressed air 83. Thereby, the workpiece 4 can be jet-processed. The workpiece 4 can be processed by scanning of the conveyor driving unit 505. When the processing of the workpiece 4 is completed, the nozzle 502 ends the injection of the abrasive 3. When the nozzle 502 ends the injection of the abrasive 3, the injection process (S41) ends. When the blast processing (S41) ends, the blast processing (S4) ends, and the process proceeds to the workpiece recovery processing (S5). In the blast processing (S41), when the abrasive 3 is continuously blasted from the nozzle 502, each processing in the blast processing (S4) is continuously performed.

(effect) As described above, according to the jet processing device 1 of the present embodiment, it is possible to jet a certain amount of abrasive 3. In addition, in the flow path 53, the extending direction of the concave portion 31 coincides with the direction of the air flow of the compressed air 75 for taking out compressed air for pressurization, so there is no need to force the abrasive 3 to fly. Furthermore, in the flow path 53, the pressure of the compressed air 75 for extraction directly acts on the abrasive 3. Therefore, the abrasive material 3 can be taken out from the concave portion 31 with a smaller pressure compared to the case where the abrasive material 3 is lifted up and taken out. By this, compared with the case where the abrasive 3 is lifted up and taken out, the take-out portion 50 can suppress the residual amount of the abrasive 3 filled into the recess 31.

The extending direction of the concave portion 31, the generation direction of the air flow of the extracted compressed air 75, and the pipeline direction of the pipe 51 are the same, so the abrasive material 3 taken out from the concave portion 31 is stably supplied from the concave portion 31 to the supply piping 60 without scattering . The cross-sectional area of the flow path 53 formed from the recess 31 and the pipe 51 can be reduced compared to the cross-sectional area of the flow path 53 of the recess 31. Thereby, even if the diameter of the nozzle 502 becomes smaller and the supply amount of the compressed air 75 for extraction in the pipeline 51 is reduced, the pressure of the compressed air 75 for extraction in the flow path 53 can be suppressed from decreasing, and filling in the concave portion can be suppressed 31 The residual amount of abrasive 3.

Both ends of the concave portion 31 are open ends, so at both ends of the concave portion 31 in the flow path 53, the obstruction and dispersion of the flow of the compressed air 75 toward the extraction nozzle 502 can be suppressed, so the abrasive 3 can be efficiently Supply to the nozzle 502.

By pressurizing the inside of the tank 11 with the compressed air 74 for the storage portion and closely filling the concave portion 31 through the filling cylinder 21, the difference in the amount of the abrasive 3 for each concave portion 31 can be suppressed to be small. An air flow of compressed air 75 for extraction is generated in the pipe 51, so that the residual amount of the abrasive 3 filled in the recess 31 can be suppressed. By supplying the auxiliary compressed air 83 from the auxiliary compressed air supply unit 80, it is possible to suppress the air of the airflow generated by the take-out unit 50 from becoming high pressure. With this, it is possible to prevent the abrasive material 3 from being taken into the supply pipe 60 regardless of the rotation of the roller 30, and it is possible to stably supply the abrasive material 3 to the nozzle 502.

(Jet processing method) As shown in FIG. 5, the injection processing method includes a filling step (S10), a moving step (S20), a supply step (S30), and an injection step (S40), and supplies the abrasive 3 to the nozzle 502. The moving step (S20) may have a flow path forming step (S22). The supply step (S30) may have an auxiliary step. The filling step (S10) is a three-step process including a valve closing process (S12), a filling part supply process (S13), and an abrasive filling process (S14). The filling step (S10) may further include a compressed air supply process for the storage unit (S11) before the valve closing process (S12).

The moving step (S20) is a step including a rotation process (S21) and a channel forming process (S22). The supplying step (S30) is a step including the extraction compressed air supplying process (S31), the auxiliary compressed air supplying process (S32), and the nozzle supplying process (S33). The assisting step assists the compressed air supply process (S32). The injection step (S40) is a step including the injection process (S41). The function and effect of the blast processing method are the same as those generated in the steps performed using the abrasive material supply device 2 in the blast processing device 1.

(Variation) The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, the jet processing device 1 only needs to include the abrasive material supply device 2 and the nozzle 502 of the processing unit 5, and it may not have any other configuration. The extraction part 50 is not limited to the above-mentioned embodiment as long as it can generate airflow in a direction parallel to the extending direction of the recess 31. For example, the opening portion 52 of the pipe 51 of the extraction portion 50 may not necessarily cover the entire one of the concave portions 31, but may cover only a part of the single concave portion 31. Alternatively, the take-out section 50 may replace the pipeline 51 and have a pipeline with a socket for receiving the abrasive 3 extruded from the recess 31.

The nozzle 502 in the embodiment is a direct pressure type, but it may be a suction type. 6 is a perspective cross-sectional view showing a polishing material supply device according to a modification. In the case of the suction type, the abrasive material 3 can be supplied to the nozzle 502A from the take-out section 50 through the supply pipe 60 by the suction negative pressure of the ejection phenomenon generated in the nozzle 502A by the nozzle 502A supplying the compressed air 75A for take-out. In the case of the suction type, the injection processing apparatus 1 may not include the supply valve 12, the compressed air duct 72, the pressurizing duct 73, or the auxiliary compressed air supply unit 80. In the case of the suction type, the supply valve 12 is unnecessary, so it can be directly connected to the classifying unit 602. The compressed air supply part 70 may have a duct. The compressed air supply unit 70 may connect one end of the duct to the compressed air supply device 71, connect the other end of the duct to the nozzle 502A, and supply the extraction compressed air 75A to the nozzle 502.

In order to suppress the influence of the vibration of the vibrator 13, the storage unit 10 or the recovery unit 6 may be provided with anti-vibration rubber outside the tank 11 or the classifying unit 602. The recess 31 may also be a groove in the circumferential direction. In this case, a plurality of concave portions 31 are formed parallel to the center axis direction as endless grooves of the roller 30 on the circumferential surface in the circumferential direction. The pipe 51 is arranged along a part of the circumference of the roller 30. The filling cylinder 21 may be provided with a protruding surface parallel to the circumferential direction so as to be adjacent to both ends of the recess 31. When the recess 31 is filled with the abrasive 3 from the filling cylinder 21, the abrasive 3 may fall from the end of the recess 31. By arranging the protruding surface, even in the case where the storage portion is filled with compressed air 74, the protruding surface can extend from the filling tube 21 to the end of the recess 31 to make the scattering phenomenon disappear.

The main body 42 may be divided into a box-shaped residual portion on the opposite side with the filling portion 20 and the roller 30 inside. When the remaining portion is filled with the abrasive material 3 from the filling portion 20 into the concave portion 31, the abrasive material 3 that is not filled into the concave portion 31 but spilled from the filling portion 20 is recovered. The remaining portion can also be attached to and detached from the body 42. The compressed air supply unit 70 and the auxiliary compressed air supply unit 80 may not supply compressed air. In this case, as long as a fixed amount of abrasive 3 can be supplied to the nozzle 502, the compressed air 74 for the storage portion or the compressed air 75 for the extraction supplied to the tank 11, the pipeline 51, the flow path 53, and the supply piping 60 may not be Compressed air.

(Example) Hereinafter, Examples and Comparative Examples of the present invention will be described. The present invention is not limited to the following examples.

The jet processing apparatus of the embodiment is the jet processing apparatus 1 shown in FIG. 1. The dimensions of the device and the conditions of spray processing are as follows. [Table 1]

The jet processing apparatus of the comparative example is different from the jet processing apparatus 1 shown in FIG. 1 only in the abrasive material supply apparatus, and the other is the same. 7 is a perspective cross-sectional view showing a polishing material supply device of a comparative example. The abrasive material supply device 900 of the comparative example is different from the abrasive material supply device 2 in the longitudinal concave portion 931, the separation and extraction portion 950, and the separation receiving portion 954, and the other configurations are the same.

The following describes the configuration of the abrasive material supply device 900 that is different from the abrasive material supply device 2. The concave portion 31 of the abrasive material supply device 2 is a groove extending in the direction of the central axis of the roller 30, and both ends are open ends. On the other hand, the longitudinal concave portion 931 of the abrasive material supply device 900 is used as the circumferential surface along the roller 30 A plurality of endless grooves in the circumferential direction are formed parallel to the direction of the central axis. As a supply path for the abrasive material 3 and the compressed air 75 for extraction, the extraction portion 50 of the abrasive material supply device 2 forms a continuous flow path 53 due to the fitting of the concave portion 31 and the pipe 51 in the opening portion 52. The vertical recessed portion 931 is exposed between the separation and extraction portion 950 and the separation receiving portion 954 of the abrasive material supply device 900. In the device size and spray processing conditions of the comparative example, the extending direction and the number of concave portions are different, and the others are the same. The comparative example has 28 longitudinal recesses 931.

The blast processing was performed using the blast processing apparatus of Examples and Comparative Examples. As a result of the jet processing, in the case of the abrasive material supply device 2 of the embodiment, after the abrasive material 3 was ejected from the nozzle 502, the residue of the abrasive material 3 in the recess 31 was not confirmed. On the other hand, in the case of the abrasive material supply device 900 of the comparative example, after the abrasive material 3 was sprayed from the nozzle 502, the residual of the abrasive material 3 in the longitudinal concave portion 931 was confirmed. Thus, compared with the comparative example, the polishing material supply device 2 of the embodiment can suppress the residual amount of the polishing material filled in the concave portion, and as a result, it was confirmed that a certain amount of polishing material can be sprayed.
