Description
本發明係關於一種噴射加工裝置及噴射加工方法。The present invention relates to a spray processing device and a spray processing method.
藉由自噴射嘴朝被加工物噴射於壓縮空氣中混合有研磨材之氣固兩相流而進行表面處理之噴射加工廣為人知。噴射加工用於鑄造品之鏽垢去除或毛糙條痕消除、除鏽、塗裝皮膜之去除、基底處理等。進而，近年來亦用於電子零件或光學零件之去毛邊、倒角、面粗糙度調整、蝕刻、皮膜去除等要求較高加工精度之用途。It is widely known that jet machining is a method of performing surface treatment by injecting a gas-solid two-phase flow of compressed air mixed with abrasive materials from a jet nozzle toward a workpiece. Injection processing is used for rust removal or rough streak removal, rust removal, coating film removal, base treatment, etc. of castings. Furthermore, in recent years, it has also been used in applications requiring higher processing accuracy such as deburring, chamfering, surface roughness adjustment, etching, and film removal of electronic parts or optical parts.
噴射加工能力受到氣固兩相流之噴射壓力、及氣固兩相流中包含之研磨材之量的影響。即，為提高加工精度，必須於噴射加工中將氣固兩相流之研磨材之含量保持為固定。The jet processing capability is affected by the jet pressure of the gas-solid two-phase flow and the amount of abrasive material contained in the gas-solid two-phase flow. That is, in order to improve the machining accuracy, the content of the abrasive material in the gas-solid two-phase flow must be kept constant during jet machining.
專利文獻1中，記載有噴射研磨材之裝置。該裝置具備：噴射嘴，其噴射研磨材；研磨材供給盤，其形成有裝填或捕獲研磨材之複數個研磨材供給孔；研磨材供給管，其與噴射嘴及研磨材供給孔連通；壓縮空氣供給源，其與研磨材供給管連通並供給壓縮空氣；導管，其將射出空氣導入；及收發管，其與導管及研磨材供給管連通。研磨材供給孔係研磨材供給盤之於圓周面沿圓周方向連續之槽，與中心軸方向平行地形成有複數個。研磨材藉由自導管及收發管射出之射出空氣而自研磨材供給孔飛揚，供給至研磨材供給管。研磨材藉由自壓縮空氣供給源供給之壓縮空氣而自研磨材供給管壓送至噴射嘴。 [先前技術文獻] [專利文獻]Patent Document 1 describes a device for jetting abrasive materials. The device is equipped with: a spray nozzle that sprays abrasive materials; a grinding material supply disc that is formed with a plurality of abrasive material supply holes for loading or capturing abrasive materials; abrasive material supply pipes that are connected to the spray nozzle and the abrasive material supply holes; and a compression An air supply source is connected to the abrasive material supply pipe and supplies compressed air; a conduit is used to introduce the injection air; and a receiving and transmitting pipe is connected to the conduit and the abrasive material supply pipe. The abrasive material supply holes are grooves formed in the circumferential surface of the abrasive material supply disk that are continuous in the circumferential direction, and a plurality of them are formed parallel to the direction of the central axis. The abrasive material is blown from the abrasive material supply hole by the jet air ejected from the duct and the receiving and transmitting tube, and is supplied to the abrasive material supply pipe. The abrasive material is pressure-fed from the abrasive material supply pipe to the injection nozzle by the compressed air supplied from the compressed air supply source.

[發明所欲解決之問題][Problem to be solved by the invention]
專利文獻1所記載之裝置中，自噴射嘴噴射之氣固兩相流之噴射壓力越高，則噴射加工能力越高。噴射嘴之噴射壓力為壓縮空氣之壓力與射出空氣之壓力之差。因此，為提高噴射壓力必須將射出空氣之壓力抑制為較小。然而，將射出空氣之壓力抑制為較小之情形時，有研磨材殘留於研磨材供給孔，從而無法將定量之研磨材供給至噴射嘴之虞。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 is. 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, in order to increase the injection pressure, the pressure of the injection air must be kept small. However, when the pressure of the injection air is kept low, there is a risk that the abrasive material remains in the abrasive material supply hole and a constant amount of abrasive material cannot be supplied to the injection nozzle.
本發明提供一種可噴射定量之研磨材之噴射加工裝置及噴射加工方法。 [解決問題之技術手段]The present invention provides a spray processing device and a spray processing method capable of spraying a fixed amount of abrasive materials. [Technical means to solve problems]
本發明之噴射加工裝置具備噴嘴、貯存部、輥、驅動部、填充部、取出部、及供給配管。噴嘴將研磨材與壓縮空氣一併噴射。貯存部將研磨材貯存於內部。輥呈圓筒狀，於圓周面上設置有槽狀之凹部，且具有於中心軸方向延伸之旋轉軸。驅動部使輥繞著旋轉軸旋轉。填充部與輥相鄰而配置，向對向之凹部填充貯存於貯存部之研磨材。取出部於較填充部更靠輥之旋轉方向之下游與輥相鄰而配置，利用與凹部之延伸方向平行之方向上產生之氣流，自對向之凹部取出研磨材。供給配管將由取出部取出之研磨材供給至噴嘴。The jet processing device of the present invention includes a nozzle, a storage part, a roller, a driving part, a filling part, a take-out part, and a supply pipe. The nozzle sprays the abrasive material together with the compressed air. The storage unit stores the abrasive materials inside. The roller is cylindrical, has groove-shaped recesses on its circumferential surface, and has a rotation axis extending in the direction of the central axis. The drive unit rotates the roller around the rotation axis. The filling part is arranged adjacent to the roller, and the abrasive material stored in the storage part is filled into the opposite concave part. The take-out part is disposed adjacent to the roller downstream of the filling part in the rotation direction of the roll, and takes out the abrasive material from the opposite recess by utilizing the air flow generated in a direction parallel to the extending direction of the recess. The supply pipe supplies the abrasive material taken out by the taking-out part to the nozzle.
根據該噴射加工裝置，研磨材自貯存部移動至填充部。研磨材於填充部填充至輥之凹部。填充至凹部之研磨材藉由以驅動部使輥繞著旋轉軸旋轉而移動至取出部。於取出部，於與凹部之延伸方向平行之方向產生有氣流，故將研磨材自凹部取出。所取出之研磨材藉由氣流而自取出部通過供給配管供給至噴嘴。於取出部，由於凹部之延伸方向與氣流之產生方向一致，故無需使研磨材飛揚之力。進而，產生氣流之空氣之壓力直接作用於研磨材。因此，與使研磨材飛揚而取出之情形相比，可以較小之壓力自凹部取出研磨材。藉此，與使研磨材飛揚而取出之情形相比，取出部可抑制填充至凹部之研磨材之殘留量。由此，本發明之噴射加工裝置可噴射定量之研磨材。According to this jet processing device, the abrasive material moves from the storage part to the filling part. The abrasive material is filled in the filling part to the concave part of the roller. The abrasive material filled into the recessed part is moved to the extraction part by rotating the roller about the rotation axis with the driving part. In the extraction part, an air flow is generated in a direction parallel to the extending direction of the recessed part, so the abrasive material is taken out from the recessed part. The taken-out abrasive material is supplied to the nozzle from the take-out part through the supply pipe by the air flow. In the extraction part, since the extension direction of the recessed part is consistent with the direction of air flow generation, there is no need to cause the abrasive material to fly. Furthermore, the pressure of the air that generates the airflow directly acts on the abrasive material. Therefore, compared with the case where the abrasive material is taken out by flying, the abrasive material can be taken out from the recessed portion with a smaller pressure. Thereby, compared with the case where the abrasive material is taken out by flying, the removal part can suppress the residual amount of the abrasive material filled in the recessed part. Therefore, the spray processing device of the present invention can spray a certain amount of abrasive material.
一實施形態之噴射加工裝置中，取出部亦可具有於與凹部之延伸方向平行之方向延伸之管路。而且，亦可藉由與取出部對向之凹部與管路之內壁而形成使取出研磨材並朝供給配管移送之氣流流通的流路。由於取出部之管路於與凹部之延伸方向平行之方向延伸，故藉由管路及對向之凹部而形成流路。藉由流路中產生氣流而將研磨材自凹部取出。流路中凹部之延伸方向、氣流之產生方向、及管路之延伸方向一致，故自凹部取出之研磨材穩定地自凹部供給至供給配管而不會飛散。由此，可自凹部對供給配管供給定量之研磨材。In the jet processing apparatus of one embodiment, the extraction part may have a pipe extending in a direction parallel to the extending direction of the recessed part. Furthermore, a flow path for flowing the air flow that takes out the abrasive material and transfers it to the supply pipe may be formed by the recess facing the take-out part and the inner wall of the pipe. Since the pipe of the extraction part extends in a direction parallel to the extending direction of the recess, a flow path is formed by the pipe and the opposite recess. The abrasive material is taken out from the recess by generating air flow in the flow path. The extending direction of the recessed portion in the flow path, the direction in which the air flow is generated, and the extending direction of the pipe are consistent, so the abrasive material taken out from the recessed portion is stably supplied from the recessed portion to the supply pipe without scattering. Thereby, a fixed amount of abrasive material can be supplied to the supply pipe from the recessed portion.
一實施形態之噴射加工裝置中，凹部係輥之於中心軸方向延伸之槽，兩端亦可為開口端。該情形時，藉由凹部之兩端開口而可抑制朝向噴嘴之氣流之阻礙及分散，故可有效率地將研磨材供給至噴嘴。由此，本發明之噴射加工裝置可噴射定量之研磨材。In the jet processing device of one embodiment, the recessed portion is a groove extending in the direction of the central axis of the roller, and both ends may also be open ends. In this case, since both ends of the recessed portion are opened, obstruction and dispersion of the air flow toward the nozzle can be suppressed, so that the abrasive material can be efficiently supplied to the nozzle. Therefore, the spray processing device of the present invention can spray a certain amount of abrasive material.
一實施形態之噴射加工裝置中，亦可進而具備輔助壓縮空氣供給部，其與供給配管連接，供給較氣流之壓力低之輔助壓縮空氣。該情形時，氣流之空氣之壓力藉由產生氣流之空氣之壓力與輔助壓縮空氣之差壓而決定。藉由自輔助壓縮空氣供給部供給輔助壓縮空氣，可抑制取出部之產生氣流之空氣成為高壓。藉此，可抑制與輥之旋轉無關地將研磨材取入至供給配管，可穩定地將研磨材供給至噴嘴。The blast processing apparatus according to one embodiment may further include an auxiliary compressed air supply unit connected to a supply pipe to supply auxiliary compressed air having a lower pressure than the air flow. In this case, the pressure of the air flow is determined by the difference between the pressure of the air that generates the air flow and the auxiliary compressed air. By supplying auxiliary compressed air from the auxiliary compressed air supply part, the air generating the air flow in the extraction part can be suppressed from becoming high pressure. This makes it possible to suppress the abrasive material from being taken into the supply pipe regardless of the rotation of the roller, and to stably supply the abrasive material to the nozzle.
一實施形態之噴射加工裝置中，亦可進而具備壓縮空氣供給部，其連接於貯存部及取出部，於噴嘴噴射研磨材之情形時，對貯存部及取出部供給加壓用壓縮空氣。而且，貯存部亦可為可密封。而且，亦可由自壓縮空氣供給部供給至貯存部之加壓用壓縮空氣，對貯存部內進行加壓。而且，亦可由自壓縮空氣供給部供給至取出部之加壓用壓縮空氣而產生氣流。該情形時，藉由自壓縮空氣供給部供給至貯存部之加壓用壓縮空氣，使能密封之貯存部內被加壓，藉此通過填充部而緊密地填充至凹部，故可將每一凹部之研磨材之量之差異抑制得較小。又，自壓縮空氣供給部對取出部供給加壓用壓縮空氣，產生氣流，故可將研磨材以擠出之方式自凹部取出。由此，可抑制填充至凹部之研磨材之殘留量。The jet processing apparatus of one embodiment may further include a compressed air supply unit connected to the storage unit and the extraction unit, and supplies pressurized compressed air to the storage unit and extraction unit when the abrasive material is sprayed from the nozzle. Moreover, the storage part may also be sealable. Furthermore, the inside of the storage part may be pressurized by pressurizing compressed air supplied from the compressed air supply part to the storage part. Furthermore, the air flow may be generated by compressed air for pressurization supplied from the compressed air supply part to the extraction part. In this case, the compressed air for pressurization supplied from the compressed air supply part to the storage part pressurizes the sealable storage part, thereby tightly filling the recessed parts through the filling part, so each recessed part can be filled The difference in the amount of abrasive material is suppressed to a small size. In addition, since the compressed air for pressurization is supplied from the compressed air supply part to the take-out part to generate an air flow, the abrasive material can be taken out from the recessed part by extrusion. This can suppress the remaining amount of the abrasive material filled into the recessed portion.
本發明之另一態樣即噴射加工方法係由噴射加工裝置進行者，且具備： (1)填充步驟，其對旋轉之圓筒狀輥之圓周面上所設置之槽狀之凹部填充研磨材； (2)移動步驟，其藉由使輥旋轉，而使凹部自經填充研磨材之位置移動至輥之旋轉方向之下游； (3)供給步驟，其利用與凹部之延伸方向平行之方向上產生之氣流，自對向之凹部取出研磨材，並供給至噴嘴；及 (4)噴射步驟，其自噴嘴將研磨材與壓縮空氣一併噴射。Another aspect of the present invention, that is, the spray processing method is performed by a spray processing device, and has: (1) Filling step, which fills the groove-shaped recess provided on the circumferential surface of the rotating cylindrical roller with abrasive material; (2) A moving step that rotates the roller to move the recessed portion from the position filled with abrasive material to the downstream of the rotation direction of the roller; (3) The supply step uses the air flow generated in a direction parallel to the extending direction of the recess to take out the abrasive material from the opposite recess and supply it to the nozzle; and (4) The spraying step is to spray the abrasive material and the compressed air together from the nozzle.
根據該噴射加工方法，於填充步驟中，將研磨材填充至輥之圓周面上所設置之凹部。於移動步驟中，填充至凹部之研磨材藉由輥旋轉而自填充有研磨材之位置移動至輥之旋轉方向之下游。供給步驟中，藉由於與凹部之延伸方向平行之方向產生氣流而將研磨材自凹部取出，並供給至噴嘴。噴射步驟中，噴嘴噴射自凹部供給之研磨材。移動步驟中，藉由輥之旋轉而使填充有研磨材之凹部依序移動，故藉由氣流而自凹部連續地取出研磨材。供給步驟中，凹部之延伸方向與氣流之產生方向一致，故無需使研磨材飛揚之力。進而，產生氣流之空氣之壓力直接作用於研磨材。因此，與使研磨材飛揚而取出之情形相比，可以較小之壓力自凹部取出研磨材。藉此，與使研磨材飛揚而取出之情形相比，取出部可抑制填充至凹部之研磨材之殘留量。由此，本發明之噴射加工方法可噴射定量之研磨材。According to this spray processing method, in the filling step, the abrasive material is filled into the recessed 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 where the abrasive material is filled to the downstream of the rotation direction of the roller by the rotation of the roller. In the supply step, the abrasive material is taken out from the recessed portion by generating an air flow in a direction parallel to the extending direction of the recessed portion, and is supplied to the nozzle. In the spraying step, the nozzle sprays the abrasive material supplied from the concave portion. In the moving step, the recessed portions filled with the abrasive material are moved sequentially by the rotation of the roller, so the abrasive material is continuously taken out from the recessed portion by the air flow. In the supply step, the extending direction of the concave portion is consistent with the direction of air flow generation, so there is no need to cause the abrasive material to fly. Furthermore, the pressure of the air that generates the airflow directly acts on the abrasive material. Therefore, compared with the case where the abrasive material is taken out by flying, the abrasive material can be taken out from the recessed portion with a smaller pressure. Thereby, compared with the case where the abrasive material is taken out by flying, the removal part can suppress the residual amount of the abrasive material filled in the recessed part. Therefore, the spray processing method of the present invention can spray a certain amount of abrasive material.
一實施形態之噴射加工方法中，移動步驟亦可具有流路形成步驟，其藉由於與凹部之延伸方向平行之方向延伸之管路之內壁、及與管路對向之凹部而形成流路。於流路形成步驟中，管路於與凹部之延伸方向平行之方向延伸，故藉由管路及對向之凹部而形成流路。藉由於流路中產生氣流而將研磨材自凹部取出。流路中凹部之延伸方向、氣流之產生方向、及管路之延伸方向一致，故自凹部取出之研磨材穩定地自凹部供給至供給配管而不會飛散。由此，可自凹部對供給配管供給定量之研磨材。In the injection processing method of one embodiment, the moving step may also include a flow path forming step in which the flow path is formed by the inner wall of the pipe extending in a direction parallel to the extending direction of the recessed portion and the recessed portion opposite to the pipe. . In the flow path forming step, the pipe extends in a direction parallel to the extending direction of the recess, so that the flow path is formed by the pipe and the opposite recess. The abrasive material is taken out from the recess by generating air flow in the flow path. The extending direction of the recessed portion in the flow path, the direction in which the air flow is generated, and the extending direction of the pipe are consistent, so the abrasive material taken out from the recessed portion is stably supplied from the recessed portion to the supply pipe without scattering. Thereby, a fixed amount of abrasive material can be supplied to the supply pipe from the recessed portion.
一實施形態之噴射加工方法中，凹部係輥之於中心軸方向延伸之槽，兩端亦可為開口端。該情形時，藉由凹部之兩端開口而抑制朝向噴嘴之氣流之阻礙及分散，故可有效率地將研磨材供給至噴嘴。由此，本發明之噴射加工方法可噴射定量之研磨材。In the spray processing method of one embodiment, the recessed portion is a groove extending in the direction of the central axis of the roller, and both ends may also be open ends. In this case, since both ends of the recessed portion are opened, obstruction and dispersion of the air flow toward the nozzle are suppressed, so that the abrasive material can be efficiently supplied to the nozzle. Therefore, the spray processing method of the present invention can spray a certain amount of abrasive material.
一實施形態之噴射加工方法中，供給步驟進而具備輔助步驟，其於對噴嘴供給研磨材時，供給較氣流之壓力低之輔助壓縮空氣。該情形時，氣流之空氣之壓力藉由產生氣流之空氣之壓力與輔助壓縮空氣之差壓而決定。於輔助步驟中，藉由供給輔助壓縮空氣而可抑制產生氣流之空氣成為高壓。藉此，可抑制與輥之旋轉無關地將研磨材取入至管路，可穩定地將研磨材供給至噴嘴。In the jet processing method of one embodiment, the supply step further includes an auxiliary step of supplying auxiliary compressed air having a lower pressure than the air flow when supplying the abrasive material to the nozzle. In this case, the pressure of the air flow is determined by the difference between the pressure of the air that generates the air flow 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. This can suppress the abrasive material from being taken into the pipe regardless of the rotation of the roller, and can stably supply the abrasive material to the nozzle.
一實施形態之噴射加工方法可為，噴射加工裝置進而具備貯存部，其貯存研磨材，且可密封；在填充步驟中，藉由對貯存部供給加壓用壓縮空氣而對貯存部內進行加壓；在供給步驟中，藉由對凹部供給加壓用壓縮空氣而產生氣流。該情形時，於填充步驟中，藉由加壓用壓縮空氣對能密封之貯存部內進行加壓而緊密地填充至凹部，故可抑制每一凹部之研磨材之量之差異。又，於供給步驟中供給加壓用壓縮空氣，產生氣流，故可將研磨材以擠出之方式自凹部取出。由此，可抑制填充至凹部之研磨材之殘留量。 [發明之效果]In one embodiment of the spray processing method, the spray processing device may further include a storage part that stores the abrasive material and is sealable; and in the filling step, the storage part is pressurized by supplying compressed air for pressurization to the storage part. ; In the supply step, the air flow is generated by supplying compressed air for pressurization to the recessed portion. In this case, in the filling step, the sealable storage portion is pressurized with pressurized air to tightly fill the recessed portions, so that the difference in the amount of abrasive material for each recessed portion can be suppressed. Furthermore, in the supply step, compressed air for pressurization is supplied to generate an air flow, so that the abrasive material can be taken out from the recessed portion by extrusion. This can suppress the remaining amount of the abrasive material filled into the recessed portion. [Effects of the invention]

The compressed air supply unit 70 may include a compressed air supply device 71 (see 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 a compressor, for example. The compressed air duct 72 is a branch pipe with one end connected to the compressed air supply device 71 and the other end of the compressed air duct 72 branching into a pipeline 51 and a pressurizing duct 73 . The pressurizing conduit 73 communicates with the tank 11 and the compressed air supply device 71 . The pressurizing conduit 73 communicates with the tank 11 on, for example, the upper surface of the tank portion of the tank 11 .

壓縮空氣供給裝置71於自噴嘴502噴射研磨材3之情形時，可將加壓用壓縮空氣中之貯存部用壓縮空氣74供給至壓縮空氣導管72及加壓用導管73。貯存部用壓縮空氣74通過壓縮空氣導管72及加壓用導管73而流入罐11內。藉由貯存部用壓縮空氣74流入罐11內而對罐11內進行加壓。藉由貯存部用壓縮空氣74對罐11內加壓而使供給閥12閉合，阻斷罐11及分級部602。由貯存部用壓縮空氣74加壓後之罐11內之研磨材3移動至與罐11連通之填充筒21。填充筒21內之研磨材3藉由罐11內之貯存部用壓縮空氣74而向下方加壓，緊密地填充至每一凹部31。When the abrasive material 3 is sprayed from the nozzle 502, the compressed air supply device 71 can supply the storage part compressed air 74 in the pressurized compressed air to the compressed air duct 72 and the pressurizing duct 73.

壓縮空氣供給裝置71於自噴嘴502噴射研磨材3之情形時，可將加壓用壓縮空氣中之取出用壓縮空氣75供給至壓縮空氣導管72及流路53。取出用壓縮空氣75於與凹部31之延伸方向平行之方向上產生氣流。由取出用壓縮空氣75產生之氣流通過壓縮空氣導管72及流路53而撞擊填充至位於流路53內之凹部31之研磨材3，藉此將研磨材3朝供給配管60之方向擠出。壓縮空氣供給裝置71連續供給作為加壓用壓縮空氣之取出用壓縮空氣75，藉此將研磨材3自流路53供給至供給配管60。When the abrasive material 3 is sprayed from the nozzle 502, the compressed air supply device 71 can supply the extraction compressed air 75 among the pressurized compressed air to the compressed air duct 72 and the flow path 53. The compressed air 75 for extraction generates an air flow in a direction parallel to the extending direction of the recess 31 . The air flow generated by the compressed air for extraction 75 passes through the compressed air duct 72 and the flow path 53 and hits the abrasive material 3 filled in the recess 31 located in the flow path 53 , thereby extruding the abrasive material 3 toward the supply pipe 60 . The compressed air supply device 71 continuously supplies the extraction compressed air 75 as pressurized compressed air, thereby supplying the abrasive material 3 from the flow path 53 to the supply pipe 60 .
輔助壓縮空氣供給部80將壓縮空氣供給至供給配管60。輔助壓縮空氣供給部80具有輔助壓縮空氣供給裝置81(參照圖1)及輔助導管82。輔助壓縮空氣供給裝置81係供給壓縮空氣之裝置。輔助壓縮空氣供給裝置81例如係壓縮機。輔助壓縮空氣供給裝置81與輔助導管82連通。輔助導管82與供給配管60及輔助壓縮空氣供給裝置81連通。輔助壓縮空氣供給裝置81通過輔助導管82而對供給配管60供給較貯存部用壓縮空氣74或取出用壓縮空氣75之壓力低之輔助壓縮空氣83。輔助壓縮空氣供給裝置81亦可根據取出用壓縮空氣75之壓力而控制輔助壓縮空氣83之供給量。研磨材3、取出用壓縮空氣75及輔助壓縮空氣83之混合流體通過供給配管60而移動至噴嘴502。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 a compressor, for example. The auxiliary compressed air supply device 81 communicates with the auxiliary duct 82 . The auxiliary duct 82 communicates with the supply pipe 60 and the auxiliary compressed air supply device 81 . The auxiliary compressed air supply device 81 supplies auxiliary compressed air 83 having 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 can also control the supply amount of the auxiliary compressed air 83 based on the pressure of the compressed air 75 for extraction. The mixed fluid of the abrasive material 3 , the compressed air for taking out 75 , and the auxiliary compressed air 83 moves to the nozzle 502 through the supply pipe 60 .
取出用壓縮空氣75之壓力係由貯存部用壓縮空氣74與輔助壓縮空氣83之差壓而決定。於貯存部用壓縮空氣74與輔助壓縮空氣83之差壓較小之情形時，取出用壓縮空氣75之壓力較小，故無法對凹部31充分地加壓，有研磨材3殘留之虞。於貯存部用壓縮空氣74與輔助壓縮空氣83之差壓較高之情形時，可與輥30之旋轉無關地將研磨材3自凹部31取入至供給配管60，從而有無法穩定地將研磨材3供給至噴嘴502之虞。為了使取出用壓縮空氣75穩定地將定量之研磨材3供給至噴嘴502，貯存部用壓縮空氣74與輔助壓縮空氣83之差壓可設定於0.01 MPa至0.1 MPa之間。流路53及加壓用導管73連通於壓縮空氣導管72，故罐11內、本體42內、及取出部50內成為大致相同之壓力。The pressure of the compressed air 75 for taking out is determined by the difference pressure between the compressed air 74 for the storage part and the auxiliary compressed air 83 . When the pressure difference between the compressed air for storage 74 and the auxiliary compressed air 83 is small, the pressure of the compressed air for taking out 75 is small, so the recess 31 cannot be fully pressurized, and the abrasive 3 may remain. When the differential pressure between the compressed air 74 for the storage part and the auxiliary compressed air 83 is high, the abrasive material 3 can be taken in from the recess 31 to the supply pipe 60 regardless of the rotation of the roller 30, and the grinding material 3 may not be stably polished. The material 3 is supplied to the nozzle 502. In order for the compressed air for taking out 75 to stably supply a certain amount of abrasive material 3 to the nozzle 502, the differential pressure between the compressed air for storage 74 and the auxiliary compressed air 83 can be set between 0.01 MPa and 0.1 MPa. The flow path 53 and the pressure conduit 73 are connected to the compressed air conduit 72, so the pressure inside the tank 11, the main body 42, and the extraction part 50 becomes substantially the same.

The airflow generated by the operation of the dust collector 702 causes the powder and granules 8 generated in the processing chamber 509 to move to the processing chamber 509, the recovery duct 601, and the classification part 602 in sequence. Through the classification of the classification unit 602, the reusable abrasive materials 3 are recovered to the tank 11, and the reusable abrasive materials 3 and cutting powder are recovered to the dust collector 702 through the dust collection duct 701.

The workpiece 4 is blast-processed by injecting the abrasive material 3 from the nozzle 502 together with the compressed air for taking out 75 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 driving unit 505 causes the workpiece 4 and the processing table 503 on the conveyor driving unit 505 to move relative to the nozzle 502 . The workpiece 4 is processed based on the trajectory set by scanning of the conveyor drive unit 505 . When the set scanning and processing are completed, the mixed fluid of the abrasive material 3 sprayed from the nozzle 502, the compressed air for extraction 75 and the auxiliary compressed air 83 is stopped.

In the storage part compressed air supply process ( S11 ), the storage part compressed air 74 is supplied into the tank 11 from the compressed air supply device 71 through the compressed air duct 72 and the pressurizing duct 73 . Next, in the valve closing process (S12), the storage part compressed air 74 is supplied into the tank 11 to pressurize the inside of the tank 11, and the supply valve 12 in the upper part of the tank 11 is closed. Thereby, the can 11 is sealed. Next, in the filling part supply process (S13), the abrasive material 3 is pressurized in the tank 11 by the storage part compressed air 74, and is moved to the filling cylinder 21. Next, in the polishing material filling process (S14), the polishing material 3 is filled into the recessed portion 31 through the filling cylinder 21.

最後，於噴射處理(S41)中，研磨材3自噴嘴502與取出用壓縮空氣75及輔助壓縮空氣83一併作為混合流體而噴射。藉此，被加工物4得以進行噴射加工。被加工物4可藉由輸送器驅動部505之掃描而加工。於被加工物4之加工結束之情形時，噴嘴502結束研磨材3之噴射。於噴嘴502結束研磨材3之噴射之情形時，噴射處理(S41)結束。藉由噴射處理(S41)結束，使噴射加工處理(S4)結束，移行至工件回收處理(S5)。於噴射處理(S41)中，於自噴嘴502連續地噴射研磨材3之情形時，連續地進行噴射加工處理(S4)內之各處理。Finally, in the injection process (S41), the abrasive material 3 is injected from the nozzle 502 together with the compressed air 75 for extraction and the auxiliary compressed air 83 as a mixed fluid. Thereby, the workpiece 4 can be blast-processed. The workpiece 4 can be processed by scanning by the conveyor driving unit 505 . When the processing of the workpiece 4 is completed, the nozzle 502 stops ejecting the abrasive material 3 . When the nozzle 502 finishes ejecting the abrasive material 3, the ejection process (S41) ends. When the injection process (S41) is completed, the injection processing process (S4) is completed, and the process proceeds to the workpiece recovery process (S5). In the spray processing (S41), when the abrasive material 3 is continuously sprayed from the nozzle 502, each process in the spray processing (S4) is continuously performed.
(效果) 以上，根據本實施形態之噴射加工裝置1，可噴射定量之研磨材3。又，於流路53，凹部31之延伸方向、與作為加壓用壓縮空氣之取出用壓縮空氣75之氣流之方向一致，故無需使研磨材3飛揚之力。進而，於流路53，取出用壓縮空氣75之壓力直接作用於研磨材3。因此，與使研磨材3飛揚而取出之情形相比，可以較小之壓力自凹部31取出研磨材3。藉此，與使研磨材3飛揚而取出之情形相比，取出部50可抑制填充至凹部31之研磨材3之殘留量。(Effect) As described above, according to the blast processing device 1 of this embodiment, a fixed amount of the abrasive material 3 can be blasted. In addition, in the flow path 53, the extending direction of the recessed portion 31 is consistent with the direction of the air flow of the extraction compressed air 75 which is the pressurizing compressed air, so there is no need to cause the abrasive 3 to fly. Furthermore, in the flow path 53 , the pressure of the compressed air for taking out 75 directly acts on the abrasive material 3 . Therefore, compared with the case where the abrasive material 3 is taken out by flying it, the abrasive material 3 can be taken out from the recessed portion 31 with a smaller pressure. Thereby, compared with the case where the abrasive material 3 is taken out by flying it, the removal part 50 can suppress the remaining amount of the abrasive material 3 filled in the recessed part 31.
凹部31之延伸方向、取出用壓縮空氣75之氣流之產生方向、及管路51之管路方向一致，故自凹部31取出之研磨材3穩定地自凹部31供給至供給配管60而不會飛散。可使自凹部31及管路51形成之流路53之剖面積對照凹部31之流路53方向之剖面積而減小。藉此，即便由噴嘴502之直徑變小而使管路51中之取出用壓縮空氣75之供給量變少，亦可抑制流路53中之取出用壓縮空氣75之壓力降低，可抑制填充至凹部31之研磨材3之殘留量。The extending direction of the recessed portion 31, the direction in which the air flow of the compressed air 75 for extraction is generated, and the direction of the pipe 51 are consistent. Therefore, the abrasive material 3 taken out from the recessed portion 31 is stably supplied from the recessed portion 31 to the supply pipe 60 without scattering. . The cross-sectional area of the flow path 53 formed from the recessed portion 31 and the pipe 51 can be reduced in comparison with the cross-sectional area of the recessed portion 31 in the direction of the flow path 53 . Thereby, even if the supply amount of the compressed air 75 for extraction in the pipe 51 is reduced due to the reduction in the diameter of the nozzle 502, the pressure of the compressed air 75 for extraction in the flow path 53 can be suppressed from decreasing, and filling into the recessed portion can be suppressed. 31 The remaining amount of abrasive material 3.
凹部31之兩端為開口端，故於流路53內之凹部31之兩端，可抑制朝向噴嘴502之取出用壓縮空氣75之氣流流動之阻礙及分散，故可有效率地將研磨材3供給至噴嘴502。Both ends of the recessed portion 31 are open ends. Therefore, at both ends of the recessed portion 31 in the flow path 53, obstruction and dispersion of the airflow of the compressed air 75 for taking out toward the nozzle 502 can be suppressed, so that the abrasive material 3 can be efficiently removed. Supplied to the nozzle 502.
藉由對罐11內以貯存部用壓縮空氣74進行加壓而通過填充筒21緊密地填充至凹部31，故可將每一凹部31之研磨材3之量之差異抑制得較小。於管路51產生取出用壓縮空氣75之氣流，故可抑制填充至凹部31之研磨材3之殘留量。藉由自輔助壓縮空氣供給部80供給輔助壓縮空氣83，可抑制於取出部50產生之氣流之空氣成為高壓。藉此，可抑制與輥30之旋轉無關地將研磨材3取入至供給配管60，可穩定地將研磨材3供給至噴嘴502。By pressurizing the tank 11 with the compressed air 74 in the storage portion and tightly filling the recessed portion 31 through the filling cylinder 21, the difference in the amount of the abrasive material 3 in each recessed portion 31 can be suppressed to a small size. The airflow of the compressed air 75 for taking out is generated in the pipe 51, so that the remaining amount of the abrasive material 3 filled into the recessed portion 31 can be suppressed. By supplying the auxiliary compressed air 83 from the auxiliary compressed air supply part 80, the air in the air flow generated in the extraction part 50 can be suppressed from becoming high pressure. This can suppress the abrasive material 3 from being taken into the supply pipe 60 regardless of the rotation of the roller 30, and can stably supply the abrasive material 3 to the nozzle 502.
(噴射加工方法) 如圖5所示，噴射加工方法係具備填充步驟(S10)、移動步驟(S20)、供給步驟(S30)、及噴射步驟(S40)，且對噴嘴502供給研磨材3之方法。移動步驟(S20)可具有流路形成步驟(S22)。供給步驟(S30)可具有輔助步驟。填充步驟(S10)係包含閥閉合處理(S12)、填充部供給處理(S13)、及研磨材填充處理(S14)之3個處理之步驟。填充步驟(S10)於閥閉合處理(S12)之前，可進而包含貯存部用壓縮空氣供給處理(S11)。(Injection processing method) As shown in FIG. 5 , the spray processing method includes a filling step (S10), a moving step (S20), a supply step (S30), and a spraying step (S40), and supplies the abrasive material 3 to the nozzle 502. The moving step (S20) may include a flow path forming step (S22). The supply step (S30) may have auxiliary steps. The filling step (S10) is a step including three processes: a valve closing process (S12), a filling part supply process (S13), and an abrasive material filling process (S14). The filling step (S10) may further include a storage part compressed air supply process (S11) before the valve closing process (S12).
移動步驟(S20)係包含旋轉處理(S21)及流路形成處理(S22)之步驟。供給步驟(S30)係包含取出用壓縮空氣供給處理(S31)、輔助壓縮空氣供給處理(S32)、及噴嘴供給處理(S33)之步驟。輔助步驟係輔助壓縮空氣供給處理(S32)。噴射步驟(S40)係包含噴射處理(S41)之步驟。噴射加工方法之作用及效果與使用噴射加工裝置1內之研磨材供給裝置2實施之步驟中產生之作用及效果相同。The moving step (S20) includes a rotation process (S21) and a flow path forming process (S22). The supply step (S30) includes steps of taking out compressed air supply processing (S31), auxiliary compressed air supply processing (S32), and nozzle supply processing (S33). The auxiliary step is the auxiliary compressed air supply process (S32). The injection step (S40) includes the injection process (S41). The functions and effects of the jet processing method are the same as those produced by the steps performed using the abrasive material supply device 2 in the jet processing device 1 .
(變化例) 以上，對本發明之實施形態進行了說明，但本發明並非限定於上述實施形態。例如，噴射加工裝置1只要僅具備研磨材供給裝置2及加工部5之噴嘴502即可，亦可不具備除該等以外之構成。取出部50只要可於與凹部31之延伸方向平行之方向產生氣流即可，並不限定於上述實施形態。例如，取出部50之管路51之開放部52亦可不必覆蓋1個凹部31之整體，而是覆蓋1個凹部31之僅一部分。或取出部50亦可代替管路51而具有具承接自凹部31擠出之研磨材3之承接口之管路。(Example of variation) The embodiments of the present invention have been described above, but the present invention is not limited to the above-mentioned 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 may not include other components. The extraction part 50 is not limited to the above-described embodiment as long as it can generate airflow in a direction parallel to the extending direction of the recessed part 31 . For example, the open part 52 of the pipe 51 of the extraction part 50 does not need to cover the entire recessed part 31, but may cover only a part of the recessed part 31. Alternatively, instead of the pipe 51 , the extraction part 50 may have a pipe having a receiving port for receiving the abrasive material 3 extruded from the recessed part 31 .
實施形態中之噴嘴502為直壓式，但亦可為吸引式。圖6係表示變化例之研磨材供給裝置之立體剖視圖。於吸引式之情形時，可藉由於噴嘴502A供給取出用壓縮空氣75A而於噴嘴502A內產生之噴射現象之吸引負壓而將研磨材3自取出部50經由供給配管60供給至噴嘴502A。於吸引式之情形時，噴射加工裝置1亦可不具備供給閥12、壓縮空氣導管72、加壓用導管73或輔助壓縮空氣供給部80。於吸引式之情形時，無需供給閥12，故亦可與分級部602直接連接。壓縮空氣供給部70可具有導管。壓縮空氣供給部70亦可使導管之一端連通於壓縮空氣供給裝置71，使導管之另一端與噴嘴502A連通，將取出用壓縮空氣75A供給至噴嘴502。The nozzle 502 in the embodiment is a direct pressure type, but it may also be a suction type. FIG. 6 is a perspective cross-sectional view showing a modified example of the abrasive material supply device. In the case of the suction type, the abrasive material 3 can be supplied from the take-out part 50 to the nozzle 502A through the supply pipe 60 by the suction negative pressure of the injection phenomenon generated in the nozzle 502A when the nozzle 502A supplies the take-out compressed air 75A. In the case of the suction type, the jet processing apparatus 1 does not need to include the supply valve 12, the compressed air duct 72, the pressurizing duct 73, or the auxiliary compressed air supply part 80. In the case of the suction type, there is no need for the supply valve 12, so it can also be directly connected to the classification part 602. The compressed air supply part 70 may have a duct. The compressed air supply part 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 compressed air 75A for extraction to the nozzle 502 .
貯存部10或回收部6為了抑制振動器13之振動之影響，亦可於罐11或分級部602之外側配置防振橡膠。凹部31亦可為圓周方向之槽。該情形時，與中心軸方向平行地形成複數個凹部31作為輥30之於圓周面沿圓周方向之無端槽。管路51以沿著輥30之一部分圓周之方式配置。填充筒21亦可以與凹部31之兩端相鄰之方式相對於圓周方向平行地設置突出面。於自填充筒21對凹部31填充有研磨材3之情形時，有研磨材3自凹部31之端掉落之虞。藉由配置突出面，即便於帶有貯存部用壓縮空氣74之填充之情形時，亦可藉由突出面自填充筒21向凹部31之端延伸而使散落現象消失。In order to suppress the influence of the vibration of the vibrator 13, the storage part 10 or the recovery part 6 may also be provided with anti-vibration rubber outside the tank 11 or the classification part 602. The recess 31 may also be a groove in the circumferential direction. In this case, a plurality of recessed portions 31 are formed parallel to the central axis direction as endless grooves in the circumferential surface of the roller 30 along the circumferential direction. The pipe 51 is arranged along a part of the circumference of the roller 30 . The filling cylinder 21 may also be provided with protruding surfaces parallel to the circumferential direction so as to be adjacent to both ends of the recess 31 . When the recessed portion 31 is filled with the abrasive material 3 from the filling cylinder 21, there is a risk that the abrasive material 3 falls from the end of the recessed portion 31. By arranging the protruding surface, even when the storage portion is filled with compressed air 74, the protruding surface extends from the filling cylinder 21 to the end of the recessed portion 31 so that the scattering phenomenon can be eliminated.
本體42亦可於內部隔著填充部20與輥30而於相反側劃分形成箱形之殘留部。殘留部於自填充部20向凹部31中填充研磨材3時，回收未填充至凹部31而是自填充部20灑落之研磨材3。殘留部亦可相對於本體42能裝卸。壓縮空氣供給部70及輔助壓縮空氣供給部80亦可不供給壓縮空氣。該情形時，只要能夠對噴嘴502供給定量之研磨材3，則供給至罐11、管路51、流路53、及供給配管60之貯存部用壓縮空氣74或取出用壓縮空氣75亦可並非壓縮空氣。The main body 42 may also be divided into a box-shaped remaining portion on the opposite side with the filling portion 20 and the roller 30 interposed therebetween. In the remaining part, when the abrasive material 3 is filled from the filling part 20 into the recessed part 31 , the abrasive material 3 that is not filled into the recessed part 31 but is scattered from the filling part 20 is recovered. The remaining portion may also be detachable from the main body 42 . The compressed air supply unit 70 and the auxiliary compressed air supply unit 80 do not need to supply compressed air. In this case, as long as a fixed amount of the abrasive 3 can be supplied to the nozzle 502, the compressed air 74 for storage or the compressed air 75 for taking out that is supplied to the tank 11, the pipe 51, the flow path 53, and the supply pipe 60 may not be Compressed air.
(實施例) 以下，對本發明之實施例及比較例進行說明。本發明並非限定於以下實施例。(Example) Hereinafter, Examples and Comparative Examples of the present invention will be described. The present invention is not limited to the following examples.
實施例之噴射加工裝置係圖1所示之噴射加工裝置1。裝置尺寸及噴射加工之條件如下。
[表1]
比較例之噴射加工裝置與圖1所示之噴射加工裝置1相比，僅研磨材供給裝置不同，其他相同。圖7係表示比較例之研磨材供給裝置之立體剖視圖。比較例之研磨材供給裝置900與研磨材供給裝置2相比，縱凹部931、分離取出部950及分離接收部954不同，其他構成相同。The blast machining device of the comparative example is the same as the blast machining device 1 shown in FIG. 1 except for the abrasive material supply device. FIG. 7 is a perspective cross-sectional view showing the abrasive material supply device of a comparative example. Compared with the abrasive supply device 2, the abrasive material supply device 900 of the comparative example is different from the abrasive material supply device 2 in the vertical recessed portion 931, the separation extraction portion 950 and the separation receiving portion 954, but the other configurations are the same.
以下說明研磨材供給裝置900中之與研磨材供給裝置2不同之構成。研磨材供給裝置2之凹部31係輥30上之於中心軸方向延伸之槽，兩端為開口端，相對於此，研磨材供給裝置900之縱凹部931係作為輥30上之於圓周面沿圓周方向之無端槽，與中心軸方向平行地形成有複數個。作為研磨材3及取出用壓縮空氣75之供給路，研磨材供給裝置2之取出部50藉由於開放部52中凹部31及管路51之嵌合而形成連續之流路53，相對於此，於研磨材供給裝置900之分離取出部950與分離接收部954之間，縱凹部931露出。比較例之裝置尺寸及噴射加工之條件中，凹部之延伸方向及個數不同，其他相同。比較例之縱凹部931為28個。The structure of the abrasive material supply device 900 that is different from that of the abrasive material supply device 2 will be described below. The recessed portion 31 of the abrasive material supply device 2 is a groove extending in the direction of the central axis on the roller 30, and both ends are open ends. In contrast, the longitudinal recess 931 of the abrasive material supply device 900 is a groove on the circumferential surface of 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 for taking out 75, the take-out part 50 of the abrasive material supply device 2 forms a continuous flow path 53 by fitting the recessed part 31 in the open part 52 and the pipe 51. In contrast, A vertical recessed portion 931 is exposed between the separation take-out portion 950 and the separation receiving portion 954 of the abrasive material supply device 900 . The device dimensions and injection processing conditions of the comparative examples are different in the extending direction and number of the recessed portions, but are otherwise the same. In the comparative example, the number of vertical recessed portions 931 is 28.
使用實施例及比較例之噴射加工裝置進行噴射加工。實施噴射加工之結果，於實施例之研磨材供給裝置2之情形時，自噴嘴502噴射研磨材3之後，未確認凹部31中之研磨材3之殘留。另一方面，於比較例之研磨材供給裝置900之情形時，自噴嘴502噴射研磨材3之後，確認縱凹部931中之研磨材3之殘留。如此，與比較例相比，實施例之研磨材供給裝置2可抑制填充至凹部之研磨材之殘留量，結果確認可噴射定量之研磨材。The blast processing apparatuses of Examples and Comparative Examples were used for blast processing. As a result of the spray 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, it was not confirmed that the abrasive material 3 remained in the recessed portion 31. On the other hand, in the case of the abrasive material supply device 900 of the comparative example, after the abrasive material 3 is sprayed from the nozzle 502, it is confirmed that the abrasive material 3 remains in the vertical recessed portion 931. In this way, compared with the comparative example, the abrasive material supply device 2 of the embodiment can suppress the remaining amount of the abrasive material filled into the recessed portion, and as a result, it was confirmed that a fixed amount of abrasive material can be sprayed.
