然而，於先前之噴射加工裝置中，維護性並不充分。例如，專利文獻1、2中所記載之噴射加工裝置於進行維護之情形時，不僅必須接近機器之前面，而且必須接近機器之側面及背面來進行維護。因此，必須於機器之周圍確保維護所需之空間。進而，作業人員必須於 機器之周圍移動。 However, in the prior art jet processing apparatus, the maintainability was not sufficient. For example, in the case of maintenance, the blast processing apparatus described in Patent Documents 1 and 2 must be close to the front surface of the machine and must be close to the front and back sides of the machine for maintenance. Therefore, the space required for maintenance must be ensured around the machine. Furthermore, the operator must Move around the machine.
於本技術領域，期待一種維護性優異之噴射加工裝置。 In the technical field, an injection processing apparatus excellent in maintainability is expected.
本發明之一形態之噴射加工裝置係具備：殼體，其於內部劃分形成噴射加工室；及噴射加工用噴嘴，其配置於噴射加工室，噴射壓縮空氣及噴射材料，且該噴射加工裝置係構成為僅自噴射加工裝置之正面便可進行維護。 An injection processing apparatus according to an aspect of the present invention includes a casing that is internally divided to form an injection processing chamber, and a jet processing nozzle that is disposed in the injection processing chamber to inject compressed air and an injection material, and the injection processing device It is configured to be maintained only from the front side of the jet processing apparatus.
根據該噴射加工裝置，僅噴射加工裝置之前面作為噴射加工裝置之維護面，即於維護時必須接近之面而構成。從而，作業人員僅自裝置之正面便可進行維護，因而作業人員之維護變得容易。進而，無需於裝置之側方或後方設置用於維護之作業空間，而只要於裝置之正面有作業空間即可。因此，該裝置之維護性優異。此處，所謂「裝置之正面」係指進行噴射加工裝置之操作(例如，噴射加工裝置之作動、停止、工件向噴射加工室內之裝載及自噴射加工室內之取出、對工件或噴射加工用噴嘴手動地進行掃描之情形時之該等之掃描等)之側。 According to the blast processing apparatus, only the front surface of the blast processing apparatus is configured as a maintenance surface of the blast processing apparatus, that is, a surface that must be approached during maintenance. Therefore, the operator can perform maintenance only from the front side of the apparatus, and maintenance of the worker becomes easy. Further, it is not necessary to provide a work space for maintenance on the side or the rear of the apparatus, and it is only necessary to have a work space on the front side of the apparatus. Therefore, the device is excellent in maintainability. Here, the "front side of the apparatus" refers to the operation of the jet processing apparatus (for example, the operation and stop of the jet processing apparatus, the loading of the workpiece into the injection processing chamber, and the extraction from the injection processing chamber, and the nozzle for the workpiece or the jet processing. The side of the scan, etc., when scanning is performed manually.

The lower outer casing can also be supported by the outer frame. Further, the upper casing may be disposed to be rotatable in the front-rear direction centering on the lower end of the back surface thereof. Since the upper casing forming the upper portion of the injection processing chamber is rotated in the front-rear direction, the operator does not need to move to the side or the rear of the apparatus to open or close the injection processing chamber.

噴射加工用噴嘴10係所謂之抽吸式。噴射加工用噴嘴10配置於下述噴射加工室R，噴射壓縮空氣及噴射材料。圖3係用以對圖2所示之噴射加工用噴嘴進行說明之模式圖(部分剖視圖)。如圖3所示，噴射加工用噴嘴10例如具備噴嘴保持器11、圓筒形狀之空氣噴嘴12、及圓筒形狀之噴射噴嘴13。噴嘴保持器11於其內部形成有將壓縮空氣與噴射材料混合之混合室11c。噴嘴保持器11具備連通於混合室11c之3個開口。例如，噴嘴保持器11具有噴射材料抽吸口11a、空氣噴嘴***口11d及噴射噴嘴***口11e。空氣噴嘴***口11d及噴射噴嘴***口11e之中心為同軸。噴射材料抽吸口11a係朝向與空氣噴嘴***口 11d及噴射噴嘴***口11e所排列之方向交叉之方向而形成。噴射材料抽吸口11a係用以將噴射材料投入(抽吸)至噴嘴保持器11內部之開口。噴射材料抽吸口11a連通於噴嘴保持器11之內部所形成之路徑11b。路徑11b連通於混合室11c。空氣噴嘴12插嵌於空氣噴嘴***口11d(噴嘴保持器11之一端側(於圖3中為上端面側))而固定。噴射噴嘴13插嵌於噴射噴嘴***口11e(噴嘴保持器11之另一端側)而固定。空氣噴嘴12及噴射噴嘴13係以各者之橫截面之中心線大致位於同一條線上之方式配置。藉由噴嘴保持器11及噴射噴嘴13之內面，於噴嘴保持器11之內部，劃分形成混合室11c。 The jet processing nozzle 10 is a so-called suction type. The jet processing nozzle 10 is disposed in the jet processing chamber R described below to inject compressed air and an injection material. Fig. 3 is a schematic view (partial cross-sectional view) for explaining the nozzle for jet machining shown in Fig. 2 . As shown in FIG. 3, the jet processing nozzle 10 includes, for example, a nozzle holder 11, a cylindrical air nozzle 12, and a cylindrical injection nozzle 13. The nozzle holder 11 is formed therein with a mixing chamber 11c that mixes compressed air with an injection material. The nozzle holder 11 has three openings that communicate with the mixing chamber 11c. For example, the nozzle holder 11 has a spray material suction port 11a, an air nozzle insertion port 11d, and a spray nozzle insertion port 11e. The center of the air nozzle insertion opening 11d and the injection nozzle insertion opening 11e is coaxial. The spray material suction port 11a is oriented toward the air nozzle insertion opening 11d is formed in a direction in which the directions in which the jet nozzle insertion ports 11e are arranged intersect. The ejection material suction port 11a is for inputting (suctioning) the ejection material to the opening inside the nozzle holder 11. The ejection material suction port 11a communicates with the path 11b formed inside the nozzle holder 11. The path 11b is in communication with the mixing chamber 11c. The air nozzle 12 is inserted and fixed to the air nozzle insertion port 11d (one end side of the nozzle holder 11 (on the upper end side in FIG. 3)). The injection nozzle 13 is inserted and fixed to the injection nozzle insertion port 11e (the other end side of the nozzle holder 11). The air nozzle 12 and the injection nozzle 13 are disposed such that the center lines of the cross sections of the respective ones are substantially on the same line. The mixing chamber 11c is divided into the inside of the nozzle holder 11 by the inner surfaces of the nozzle holder 11 and the injection nozzle 13.
空氣噴嘴12係用以向噴嘴保持器11內部噴射壓縮空氣之噴嘴。於壓縮空氣之路徑12a，具有用以使壓縮空氣之流速加速之加速部12b。空氣噴嘴12連接於未圖示之壓縮機。 The air nozzle 12 is a nozzle for injecting compressed air into the inside of the nozzle holder 11. The compressed air path 12a has an acceleration portion 12b for accelerating the flow rate of the compressed air. The air nozzle 12 is connected to a compressor (not shown).
噴射噴嘴13係用以將已於混合室11c混合之壓縮空氣與噴射材料作為氣固兩相流自噴射口13a噴射之噴嘴。氣固兩相流之路徑係藉由自噴嘴保持器11側端面朝向前端連續地縮徑之加速部13c、及對已通過加速部13c之氣固兩相流之流動進行整流之整流部13d而形成。 The injection nozzle 13 is a nozzle for injecting compressed air and an injection material which have been mixed in the mixing chamber 11c as a gas-solid two-phase flow from the injection port 13a. The path of the gas-solid two-phase flow is an acceleration portion 13c that is continuously reduced in diameter from the end surface of the nozzle holder 11 toward the tip end, and a rectifying portion 13d that rectifies the flow of the gas-solid two-phase flow that has passed through the acceleration portion 13c. form.
若藉由空氣噴嘴12向噴嘴內部噴射壓縮空氣，則於噴嘴保持器11之內部，即混合室11c產生抽吸力。因該抽吸力之大小視空氣噴嘴12之前端與噴射噴嘴13之內壁面之距離而變化，故以成為最佳抽吸力之方式於上下方向上對空氣噴嘴12進行調整，並藉由未圖示之螺栓等將空氣噴嘴12固定於噴嘴保持器11。自噴射材料抽吸口11a投入(抽吸)之噴射材料通過路徑11b，移送至混合室11c。到達混合室11c之噴射材料與壓縮空氣混合。混合之壓縮空氣與噴射材料通過路徑13b，自噴射口13a噴射。 When the compressed air is injected into the inside of the nozzle by the air nozzle 12, a suction force is generated inside the nozzle holder 11, that is, the mixing chamber 11c. Since the magnitude of the suction force varies depending on the distance between the front end of the air nozzle 12 and the inner wall surface of the injection nozzle 13, the air nozzle 12 is adjusted in the up and down direction by the optimum suction force, and The air nozzle 12 is fixed to the nozzle holder 11 by a bolt or the like as shown. The injection material that is injected (sucked) from the ejection material suction port 11a passes through the path 11b and is transferred to the mixing chamber 11c. The spray material reaching the mixing chamber 11c is mixed with the compressed air. The mixed compressed air and the ejection material are ejected from the ejection opening 13a through the path 13b.
來自噴射噴嘴13之噴射壓力之調整係藉由配置於下述外框23之前面(噴射加工裝置1之正面側)之壓力調整閥V(操作元件)而進行。壓 力調整閥V設置於外部之空氣壓縮機(未圖示)至空氣噴嘴12之路徑。以於自噴射噴嘴13噴射時，連接於壓力調整閥V之壓力計之數值指向特定之壓力之方式，藉由壓力調整閥V調整壓縮空氣之壓力。藉由該構成，僅於噴射加工裝置1之正面便至少可進行氣固兩相流之噴射壓力之確認及設定。 The adjustment of the injection pressure from the injection nozzle 13 is performed by a pressure regulating valve V (operating element) disposed on the front surface of the outer frame 23 (the front side of the jet processing apparatus 1). Pressure The force adjustment valve V is disposed in a path from an external air compressor (not shown) to the air nozzle 12. When the injection nozzle 13 is injected, the value of the pressure gauge connected to the pressure regulating valve V is directed to a specific pressure, and the pressure of the compressed air is adjusted by the pressure regulating valve V. According to this configuration, at least the injection pressure of the gas-solid two-phase flow can be confirmed and set only on the front surface of the jet processing apparatus 1.
於空氣壓縮機至空氣噴嘴12之路徑之途中，例如，進而設置有電磁閥E及連接於電磁閥E之腳踏開關(未圖示)。藉由該腳踏開關，可切換電磁閥E之ON、OFF，即壓縮空氣向空氣噴嘴12之供給之有無。腳踏開關可配置於噴射加工裝置1之前方，以便作業人員可於正進行噴射加工時操作腳踏開關。藉由該構成，僅於噴射加工裝置1之正面便至少可進行噴射材料之噴射之ON、OFF之切換。 In the middle of the path from the air compressor to the air nozzle 12, for example, a solenoid valve E and a foot switch (not shown) connected to the solenoid valve E are further provided. With the foot switch, the ON/OFF of the solenoid valve E, that is, the supply of compressed air to the air nozzle 12 can be switched. The foot switch can be disposed in front of the jet processing apparatus 1 so that the operator can operate the foot switch while the jet processing is being performed. According to this configuration, at least the ON and OFF of the ejection of the ejection material can be performed only on the front surface of the jet processing apparatus 1.

The lower casing 22 has a slightly larger upper end surface than the bottom surface of the upper casing 21, and has a shape in which the area of the cross section continuously decreases toward the bottom surface. At the upper end of the lower casing 22, a casing 22a is fitted to the lower end of the upper casing 21. Further, an input member 34 is connected to the lower end of the lower casing 22, and the injection processing chamber R and the classification mechanism 30 are connected via the input member 34.
外框23例如呈上下端面開口之箱狀。開口之形狀例如為四邊形。外框23立設置於基台70。外框23之上端固定於下部外殼22之殼體22a。即，外框23支持下部外殼22。外框23可以使下部外殼22相對於基台70成特定之高度之方式將該下部外殼22固定。於外框23之前面及背面之下部，分別設置有可接近其內部之開口部(切口)23a、23b。外框23之前面側之開口部23a可於如下所述，對分級機構30、抽吸機構40、儲存進料斗50、或噴射材料移送機構60進行維護時，供作業人員接近該等構成要素而使用。外框23之背面側之開口部23b可進行藉由抽吸機構40而抽吸之空氣之排氣及抽吸機構40中所產生之熱之散熱。 The outer frame 23 has, for example, a box shape in which the upper and lower end faces are open. The shape of the opening is, for example, a quadrangle. The outer frame 23 is vertically disposed on the base 70. The upper end of the outer frame 23 is fixed to the casing 22a of the lower casing 22. That is, the outer frame 23 supports the lower outer casing 22. The outer frame 23 can secure the lower outer casing 22 to a lower height relative to the base 70. Openings (notches) 23a, 23b that are close to the inside are provided on the front surface and the lower surface of the outer frame 23, respectively. The opening portion 23a on the front surface side of the outer frame 23 can be used by the operator to approach the components when the classification mechanism 30, the suction mechanism 40, the storage hopper 50, or the injection material transfer mechanism 60 is maintained as described below. use. The opening portion 23b on the back side of the outer frame 23 allows the exhaust of the air sucked by the suction mechanism 40 and the heat generated by the suction mechanism 40 to dissipate heat.
又，於外框23之背面，以上部外殼21之背面之下端與外框23(即下部外殼22)之背面之上端連接之方式設置有鉸鏈24。藉此，上部外殼21設置成以其背面之下端為中心而可於前後方向上轉動。更具體而言，上部外殼21可以鉸鏈24為中心而轉動。藉由上部外殼21之轉動，可於噴射加工裝置1之前面打開或關閉噴射加工室R。又，於外框23之前面設置有閂鎖25。藉由閂鎖25，固定上部外殼21與外框23(即下部外殼22)。 Further, on the back surface of the outer frame 23, a hinge 24 is provided so that the lower end of the upper surface of the upper casing 21 is connected to the upper end of the rear surface of the outer frame 23 (i.e., the lower casing 22). Thereby, the upper casing 21 is disposed to be rotatable in the front-rear direction centering on the lower end of the back surface thereof. More specifically, the upper casing 21 is rotatable about the hinge 24. By the rotation of the upper casing 21, the injection processing chamber R can be opened or closed in front of the jet processing apparatus 1. Further, a latch 25 is provided on the front surface of the outer frame 23. The upper casing 21 and the outer frame 23 (i.e., the lower casing 22) are fixed by the latch 25.
於外框23之側面，設置有對上部外殼21已關閉之情況進行檢測 之感測器S。於藉由該感測器S未檢測到上部外殼21已關閉之情形時，噴射加工裝置1不作動。即，無法於噴射加工室R打開之狀態下將噴射材料自噴射加工用噴嘴10噴射。因此，作業人員之安全性提高。 On the side of the outer frame 23, it is provided that the upper casing 21 is closed.

In other words, the ejection material cannot be ejected from the ejection processing nozzle 10 in a state where the ejection processing chamber R is opened. Therefore, the safety of the operator is improved.

The processing plate 26 is provided with a plurality of openings through which the powder or granules containing the blasting material pass toward the bottom.
圖4係用以對圖2所示之分級機構30進行說明之模式圖。圖4(A)為側面圖，圖4(B)為表示圖4(A)中之A-A剖面之模式圖。如圖4所示，向本實施形態之分級機構30，自下部外殼22供給包含噴射材料之粉粒體。分級機構30例如具備兩端開口之圓筒狀之整流構件31、大致箱狀之分級構件32、圓筒狀之抽吸構件33及矩形筒狀之投入構件34。 Fig. 4 is a schematic view for explaining the classifying mechanism 30 shown in Fig. 2. 4(A) is a side view, and FIG. 4(B) is a schematic view showing a cross section taken along the line A-A in FIG. 4(A). As shown in Fig. 4, the classification mechanism 30 of the present embodiment supplies the powder or granule containing the injection material from the lower casing 22. The classification mechanism 30 includes, for example, a cylindrical rectifying member 31 that is open at both ends, a substantially box-shaped classifying member 32, a cylindrical suction member 33, and a rectangular cylindrical input member 34.
圓筒狀之整流構件31之軸線(中心軸)沿水平方向(X方向)延伸。整流構件31之一端面(於圖4(B)中為右側之端面)係藉由環狀之封閉板31a及下述抽吸構件33而封閉。於整流構件31之下端，連接有投入構件34。藉此，粉粒體經由投入構件34供給至整流構件31之內部。整流構件31之另一端(於圖4(B)中為左側之端面)連接於分級構件32之上部。藉此，整流構件31之內部與分級構件32之內部連通。 The axis (center axis) of the cylindrical flow regulating member 31 extends in the horizontal direction (X direction). One end surface of the rectifying member 31 (the end surface on the right side in Fig. 4(B)) is closed by the annular closing plate 31a and the suction member 33 described below. An input member 34 is connected to the lower end of the flow regulating member 31. Thereby, the powder or granules are supplied to the inside of the flow regulating member 31 via the input member 34. The other end of the rectifying member 31 (the end surface on the left side in Fig. 4(B)) is connected to the upper portion of the classifying member 32. Thereby, the inside of the rectifying member 31 communicates with the inside of the classifying member 32.
箱狀之分級構件32具有上部及寬度較上部短小之下部，該上部自正面方向(Y軸之正方向)觀察呈縱長之四邊形，自側面方向(X方向)觀察呈圓形。更詳細而言，分級構件32之上部之自裝置側面方向(圖4(A)之視點(X方向))觀察之縱剖面為整流構件31之直徑以上之圓形。分級構件32以相對於整流構件31之軸線成直角之方式連接於該整流構件31之另一端。分級構件32之下部以間隔自上端朝向下端變窄之方式延伸。即，分級構件32之下部之橫截面之面積朝向下端連續地縮小。分級構件32之側面下端部開口。於分級構件32之底部固定有儲存進料斗50。 The box-shaped classifying member 32 has an upper portion and a lower portion having a shorter width than the upper portion, and the upper portion has a vertically long quadrangular shape when viewed from the front direction (the positive direction of the Y-axis), and has a circular shape when viewed from the side direction (X direction). More specifically, the longitudinal section of the upper portion of the classifying member 32 viewed from the apparatus side direction (the viewpoint (X direction) of FIG. 4(A)) is a circle having a diameter equal to or larger than the diameter of the rectifying member 31. The classifying member 32 is coupled to the other end of the rectifying member 31 at a right angle to the axis of the rectifying member 31. The lower portion of the classifying member 32 extends in such a manner that the interval narrows from the upper end toward the lower end. That is, the area of the cross section of the lower portion of the classifying member 32 is continuously reduced toward the lower end. The lower end portion of the side of the classifying member 32 is open. A storage hopper 50 is fixed to the bottom of the classifying member 32.
圓筒形狀之抽吸構件33之軸線(中心軸)沿水平方向(X方向)延伸。抽吸構件33之外徑小於整流構件31之內徑。抽吸構件33配置於整流構件31之內部。抽吸構件33與整流構件31呈同心狀配置。從而，藉由整流構件31及抽吸構件33，形成雙重圓筒構造。抽吸構件33之一端部(於圖4(B)中為右側之端部)連接於環狀之封閉板31a之開口部。抽吸構件33之一端部連接於抽吸機構40。 The axis (central axis) of the cylindrical suction member 33 extends in the horizontal direction (X direction). The outer diameter of the suction member 33 is smaller than the inner diameter of the flow regulating member 31. The suction member 33 is disposed inside the flow regulating member 31. The suction member 33 and the rectifying member 31 are arranged concentrically. Thereby, the double cylinder structure is formed by the flow regulating member 31 and the suction member 33. One end portion of the suction member 33 (the end portion on the right side in Fig. 4(B)) is connected to the opening portion of the annular closing plate 31a. One end of the suction member 33 is connected to the suction mechanism 40.
若使抽吸機構40作動，則由抽吸構件33對整流構件31及分級構件32之空間進行抽吸，因而外氣及包含噴射材料之粉粒體自投入構件34被抽吸至分級機構30內。被投入之外氣藉由來自抽吸構件33之抽吸力而朝向分級構件32。此處，如圖4(A)所示，投入構件34係以其下端面34a相對於整流構件31之圓周內壁面成為切線之方式設置。藉此，被抽吸之外氣以沿整流構件31之內壁朝向分級構件32之方式呈螺旋狀於整流構件31之內壁面及抽吸構件33之外壁面上所形成之流路(整流部31b)流動。包含噴射材料之粉粒體借勢於該氣流而朝向分級構件32移送。再者，投入構件34亦可以其上端面34b之延長假想線相對於抽吸構件33之圓周外壁面成為切線之方式設置。於該情形時，被抽吸之外氣亦於整流部31b以沿抽吸構件33之外壁朝向分級構件32之方式呈螺旋狀流動，包含噴射材料之粉粒體借勢於該氣流而移送。 When the suction mechanism 40 is actuated, the space of the rectifying member 31 and the classifying member 32 is sucked by the suction member 33, so that the outside air and the powder or granule containing the injection material are sucked from the input member 34 to the classifying mechanism 30. Inside. The outside air is introduced toward the classifying member 32 by the suction force from the suction member 33. Here, as shown in FIG. 4(A), the input member 34 is provided such that the lower end surface 34a thereof is tangent to the circumferential inner wall surface of the flow regulating member 31. Thereby, the suctioned outside air is spirally formed on the inner wall surface of the flow regulating member 31 and the outer wall surface of the suction member 33 so as to be along the inner wall of the flow regulating member 31 toward the classifying member 32 (rectifier portion) 31b) Flow. The powder or granule containing the blast material is transferred toward the classifying member 32 by the air current. Further, the input member 34 may be provided such that the extended imaginary line of the upper end surface 34b is tangent to the circumferential outer wall surface of the suction member 33. In this case, the gas to be pumped also flows in a spiral shape toward the classifying member 32 along the outer wall of the suction member 33 in the rectifying portion 31b, and the powder or granule containing the injection material is transferred by the air current.
已通過整流部31b之包含噴射材料之粉粒體進而一面回旋一面繼續前進而到達分級構件32。然後，一面繼續回旋一面減速地進而繼續前進(圖4(B)中之箭頭「a」)。於減速時，作為較重粒子之可再使用之噴射材料藉由重力下落至分級構件32之底部，堆積於儲存進料斗50(同圖中之箭頭「b」)。另一方面，作為較輕粒子之不可再使用之噴射材料及噴射加工中所產生之切削粉(對該等進行統稱，以後記作「粉塵」)被抽吸構件33抽吸至抽吸機構40(同圖中之箭頭「c」)。 The powder or granule containing the injection material passing through the rectifying portion 31b is further rotated while being advanced to reach the classifying member 32. Then, while continuing to swing, the speed is decelerated and the progress is continued (arrow "a" in Fig. 4(B)). At the time of deceleration, the reusable spray material as a heavier particle falls by gravity to the bottom of the classifying member 32, and is deposited in the storage hopper 50 (arrow "b" in the same figure). On the other hand, the spray material which is not reusable as a lighter particle and the cutting powder which is generated in the blasting process (collectively referred to as "dust" hereinafter) are sucked by the suction member 33 to the suction mechanism 40. (The arrow "c" in the same figure).
此處，若整流部31b之長度或整流部31b之前端面(即，抽吸構件 33之前端面，且圖4(B)中之左側剖面)至位於與該前端面對向之位置之分級構件32之壁面之長度過短，則分級效率降低。若整流部31b之長度超過必要程度地過短，則無法充分獲得供包含噴射材料之粉粒體回旋之力，故而於剛通過整流部31b之後便被自整流構件31之前端面抽吸。此時，可再利用之噴射材料亦被抽吸，故而分級效率降低。又，若整流部31b之前端面至位於與該前端面對向之位置之分級構件32之壁面之長度超過必要程度地過短，則噴射材料未得到充分減速，與壁面發生碰撞而反彈，到達抽吸構件33附近之可再利用之噴射材料被自抽吸構件33之前端面抽吸，故而分級效率降低。另一方面，若整流部31b之長度或整流部31b之前端面至位於與該前端面對向之位置之分級構件32之壁面之長度超過必要程度地過長，則分級機構30本身大型化。因此，為獲得良好之分級效率，且避免分級機構30超過必要程度地大型化，亦可於1.25~1.75之範圍內設定整流部31b之前端面至位於與該前端面對向之位置之分級構件32之壁面之長度L2相對於整流部31b之長度L1之比(L2/L1)。 Here, the length of the rectifying portion 31b or the front end surface of the rectifying portion 31b (that is, the suction member) The length of the front end face of 33, and the left side section in Fig. 4(B) to the wall surface of the classifying member 32 located at a position facing the front end is too short, and the classification efficiency is lowered. When the length of the rectifying portion 31b is excessively shorter than necessary, the force for swirling the powder or granule containing the injection material cannot be sufficiently obtained. Therefore, it is sucked from the front end surface of the rectifying member 31 immediately after passing through the rectifying portion 31b. At this time, the reusable spray material is also sucked, so the classification efficiency is lowered. Further, when the length of the front end surface of the rectifying portion 31b to the wall surface of the classifying member 32 located at a position facing the front end is excessively shorter than necessary, the ejection material is not sufficiently decelerated, and collides with the wall surface to rebound and reach the pumping. The reusable spray material in the vicinity of the suction member 33 is sucked from the front end surface of the suction member 33, so that the classification efficiency is lowered. On the other hand, if the length of the rectifying portion 31b or the length of the front end surface of the rectifying portion 31b to the wall surface of the classifying member 32 located at a position facing the front end is excessively longer than necessary, the classifying mechanism 30 itself is enlarged. Therefore, in order to obtain good classification efficiency and to prevent the classification mechanism 30 from being enlarged more than necessary, the front end surface of the rectifying portion 31b may be set to the grading member 32 located at a position facing the front end in the range of 1.25 to 1.75. The ratio (L2/L1) of the length L2 of the wall surface to the length L1 of the rectifying portion 31b.
於整流部31b中，若整流構件31之直徑相對於抽吸構件33之直徑過小則整流部31b之空間會過窄而妨礙包含噴射材料之粉粒體之通過。其結果，於整流部31b中，包含噴射材料之粉粒體朝著分級構件32前進之速度變慢，於剛通過整流部31b之後便被自抽吸構件33之前端面抽吸。此時，可再利用之噴射材料亦被抽吸，故而分級效率降低。因此，必須以成為可供包含噴射材料之粉粒體良好地通過之大小之方式擴大整流構件31之直徑，但若過大則分級機構30大型化。又，若抽吸構件33之直徑過小則抽吸速度變得過慢，可再使用之噴射材料亦被抽吸，故而分級效率降低。於抽吸構件33之直徑過大之情形時，如上所述必須擴大整流構件31之直徑，故而分級機構30大型化。因此，為獲得良好之分級效率，且避免分級機構30超過必要程度地大型 化，亦可於1.5~2.0之範圍內設定整流構件31之直徑D2相對於抽吸構件33之直徑D1之比(D2/D1)。 In the flow rectifying portion 31b, when the diameter of the flow regulating member 31 is too small with respect to the diameter of the suction member 33, the space of the rectifying portion 31b is too narrow to hinder the passage of the powder or granule containing the injection material. As a result, in the rectifying portion 31b, the speed at which the powder or granule containing the injection material advances toward the classifying member 32 becomes slow, and is sucked from the front end surface of the suction member 33 immediately after passing through the rectifying portion 31b. At this time, the reusable spray material is also sucked, so the classification efficiency is lowered. Therefore, it is necessary to enlarge the diameter of the flow regulating member 31 so that the powder or granules containing the spray material can pass satisfactorily. However, if the size is too large, the classification mechanism 30 is enlarged. Further, if the diameter of the suction member 33 is too small, the suction speed becomes too slow, and the reusable ejection material is also sucked, so that the classification efficiency is lowered. When the diameter of the suction member 33 is excessively large, the diameter of the flow regulating member 31 must be enlarged as described above, and the classification mechanism 30 is increased in size. Therefore, in order to obtain good classification efficiency, and to avoid the classification mechanism 30 exceeding the necessary degree The ratio (D2/D1) of the diameter D2 of the rectifying member 31 to the diameter D1 of the suction member 33 can also be set in the range of 1.5 to 2.0.
若整流部31b中之風量過慢，則包含噴射材料之粉粒體之速度變得過慢，於剛通過整流部31b之後便會被自抽吸構件33之前端面抽吸。若風量過快，則包含噴射材料之粉粒體之速度變得過快，與分級構件32之壁面碰撞而反彈之包含噴射材料之粉粒體移動至抽吸構件33之前端附近。無論於哪種情形時，可再利用之噴射材料均會被抽吸，故而分級效率降低。因此，為獲得良好之分級效率，亦可以使整流部31b之前端之風量為2.1~3.6m3/min之方式進行調整。 When the air volume in the rectifying portion 31b is too slow, the speed of the powder or granule containing the injection material becomes too slow, and is sucked from the front end surface of the suction member 33 immediately after passing through the rectifying portion 31b. If the air volume is too fast, the speed of the powder or granule containing the spray material becomes too fast, and the powder or granule containing the spray material which collides with the wall surface of the classifying member 32 and moves back to the vicinity of the front end of the suction member 33. In either case, the reusable spray material is sucked, so the classification efficiency is lowered. Therefore, in order to obtain good classification efficiency, the air volume at the front end of the rectifying portion 31b can be adjusted so as to be 2.1 to 3.6 m 3 /min.
於本實施形態之分級機構30中，可將噴射加工中通常所使用之噴射材料良好地分級。噴射材料可列舉：鐵系及非鐵金屬系之珠狀物(shot)、切線狀物(cut wire)及粒狀物(grid)、陶瓷之粒子(例如，氧化鋁、碳化矽、鋯英石等)、玻璃之粒子、樹脂之粒子(例如，尼龍樹脂、三聚氰胺樹脂、尿素樹脂等)、植物種子之粒子(例如，核桃、桃子等)等。結合該等噴射材料之比重，適當選擇其粒子徑。例如，於比重為1.1~4.0之噴射材料(氧化鋁質之粒子、玻璃顆粒、尼龍、核桃等)之情形時，可自45~850μm之範圍選擇粒子徑，於比重為7.2~7.9之噴射材料(鐵系之珠狀物等)之情形時可自45~500μm之範圍選擇粒子徑。 In the classification mechanism 30 of the present embodiment, the ejection materials generally used in the blast processing can be well classified. Examples of the spray material include iron and non-ferrous metal shots, cut wires and grids, and ceramic particles (for example, alumina, tantalum carbide, zircon). Etc.), particles of glass, particles of resin (for example, nylon resin, melamine resin, urea resin, etc.), particles of plant seeds (for example, walnuts, peaches, etc.). The particle diameter is appropriately selected in accordance with the specific gravity of the spray materials. For example, in the case of a spray material (alumina particles, glass particles, nylon, walnut, etc.) having a specific gravity of 1.1 to 4.0, the particle diameter can be selected from the range of 45 to 850 μm, and the spray material having a specific gravity of 7.2 to 7.9 can be selected. In the case of an iron-based bead or the like, the particle diameter can be selected from the range of 45 to 500 μm.
分級構件32並不限定於本實施形態之形狀，亦可設定為圓筒形狀或多角形之筒形狀。又，亦可如本實施形態般，具有朝向下端連續地縮小橫截面之面積之部分。 The classifying member 32 is not limited to the shape of the embodiment, and may be set to have a cylindrical shape or a polygonal cylindrical shape. Further, as in the present embodiment, it is possible to have a portion in which the area of the cross section is continuously reduced toward the lower end.
本實施形態之分級機構30較縱型之旋風分離型分級機一類之先前之噴射加工裝置中所使用之分級機更小型。因此，可將分級機構30配置於基台70與下部外殼22之間之空間。其結果，與先前之噴射加工裝置相比可將高度降低。因此，無需於噴射加工裝置1之旁邊設置用 來放置用以維護分級機構30之馬梯之空間，分級機構30之維護僅於噴射加工裝置1之正面便可進行。 The classifying mechanism 30 of the present embodiment is smaller than the classifier used in the prior art jet processing apparatus such as the vertical cyclone type classifier. Therefore, the classifying mechanism 30 can be disposed in a space between the base 70 and the lower casing 22. As a result, the height can be lowered as compared with the prior art jet processing apparatus. Therefore, it is not necessary to set it beside the jet processing apparatus 1. The space for maintaining the ladder of the classification mechanism 30 is placed, and the maintenance of the classification mechanism 30 can be performed only on the front side of the jet processing apparatus 1.
抽吸機構40具備：抽吸機構本體41，其係密閉之箱體；及抽吸力產生源42，其連接於抽吸機構本體41。抽吸機構本體41連接於分級機構30，於位於抽吸構件33與抽吸力產生源42之路徑之抽吸機構本體41內，配置有用以捕獲粉塵之過濾器(未圖示)。若使抽吸力產生源42作動，則分級機構30內之粉塵與空氣一併抽吸至抽吸機構本體41。被抽吸之粉塵於朝向抽吸力產生源42進而移送時，被過濾器捕獲，僅空氣移送至抽吸力產生源42。被捕獲之粉塵可藉由作業人員經由開口部23a接近設置於抽吸機構本體41之前面之開閉扉41a，打開開閉扉41a，卸下過濾器而回收。再者，抽吸力產生源42之作動之切換係藉由配置於外框23之前面之操作面板P之操作而進行。 The suction mechanism 40 includes a suction mechanism main body 41 that is a sealed casing, and a suction force generation source 42 that is connected to the suction mechanism main body 41. The suction mechanism main body 41 is connected to the classification mechanism 30, and a filter (not shown) for collecting dust is disposed in the suction mechanism main body 41 located in the path of the suction member 33 and the suction force generation source 42. When the suction force generating source 42 is actuated, the dust in the classifying mechanism 30 is sucked together with the air to the suction mechanism body 41. When the sucked dust is transferred to the suction force generating source 42 and further transferred, it is captured by the filter, and only the air is transferred to the suction force generating source 42. The dust to be caught can be opened by the operator close to the opening/closing jaw 41a provided on the front surface of the suction mechanism main body 41 via the opening 23a, and the opening and closing jaw 41a is opened, and the filter is removed and collected. Further, the switching of the actuation of the suction force generating source 42 is performed by the operation of the operation panel P disposed on the front surface of the outer frame 23.
圖5係對圖2所示之儲存進料斗及噴射材料移送機構進行說明之模式圖。儲存進料斗50如圖5所示，上端固定於分級機構30之分級構件32之底部。儲存進料斗50係其內部之空間與分級機構30連通之箱狀。於儲存進料斗50，設置有噴射材料之排出機構。該排出機構係由設置於儲存進料斗50之底部之噴射材料排出構件51及封閉栓52所構成。於噴射材料排出構件51之下端設置有用以將儲存進料斗50內之噴射材料排出之開口。封閉栓52可使該開口封閉。於本實施形態中，以覆蓋設置於儲存進料斗50之底部之開口之方式固定兩端開口之圓筒形狀之噴射材料排出構件51之一端。而且，於噴射材料排出構件51之另一端嵌著有由橡膠構成之圓錐梯形狀之封閉栓52。 Fig. 5 is a schematic view for explaining the storage hopper and the injection material transfer mechanism shown in Fig. 2. The storage hopper 50 is fixed to the bottom of the classifying member 32 of the classifying mechanism 30 as shown in FIG. The storage hopper 50 is a box shape in which the space inside thereof communicates with the classification mechanism 30. In the storage hopper 50, a discharge mechanism for the blast material is provided. The discharge mechanism is composed of an injection material discharge member 51 and a closing plug 52 which are provided at the bottom of the storage hopper 50. An opening for discharging the ejection material stored in the feed hopper 50 is provided at the lower end of the ejection material discharge member 51. Closure pin 52 can close the opening. In the present embodiment, one end of the cylindrical ejection material discharge member 51 which is open at both ends is fixed so as to cover the opening provided at the bottom of the storage hopper 50. Further, a conical ladder-shaped closing plug 52 made of rubber is fitted to the other end of the ejection material discharge member 51.
為將貯存於儲存進料斗50之噴射材料移送至噴射加工用噴嘴10，於儲存進料斗50，配置有噴射材料之噴射材料移送機構60。噴射材料移送機構60如圖5所示，具備圓管狀之噴射材料取出管61、圓管狀之外氣導入管安裝構件62及外氣導入管63。噴射材料取出管61係以 貫通儲存進料斗50之側壁(於圖5中為左側壁、Y軸之負方向)之方式固定。外氣導入管安裝構件62係以貫通儲存進料斗50之與噴射材料取出管61對向之側壁(於圖5中為右側壁、Y軸之正方向)之方式固定。外氣導入管63係插通於外氣導入管安裝構件62而固定。 In order to transfer the ejected material stored in the storage hopper 50 to the jet processing nozzle 10, the ejecting material transfer mechanism 60 of the ejecting material is disposed in the storage hopper 50. As shown in FIG. 5, the injection material transfer mechanism 60 includes a circular tubular ejection material take-out tube 61, a circular tubular outer gas introduction tube mounting member 62, and an external air introduction tube 63. The spray material take-out tube 61 is The side wall of the storage hopper 50 is fixed (in the left side wall of FIG. 5, the negative direction of the Y-axis). The external air introduction pipe mounting member 62 is fixed so as to penetrate the side wall of the storage hopper 50 opposite to the injection material take-out pipe 61 (the right side wall and the Y-axis in FIG. 5). The outside air introducing pipe 63 is inserted and fixed to the outside air introducing pipe mounting member 62.
外氣導入管63係以其前端位於噴射材料取出管61之中之方式固定。噴射材料取出管61連接於噴射加工用噴嘴10之噴射材料抽吸口11a。藉由於噴射加工用噴嘴10之內部產生之抽吸力，於噴射材料取出管61內產生朝向該噴射加工用噴嘴10之氣流。此時，自外氣導入管63抽吸外氣。即，於外氣導入管63之前端形成外氣流噴射之狀態。藉由該氣流，於噴射材料取出管61之右端附近產生朝向噴射材料抽吸口11a之氣流。儲存進料斗50內之噴射材料借勢於該氣流，抽吸至噴射材料取出管61，並移送至噴射加工用噴嘴10。 The external air introduction pipe 63 is fixed such that its front end is located in the injection material take-out pipe 61. The ejection material take-out tube 61 is connected to the ejection material suction port 11a of the ejection processing nozzle 10. The airflow toward the jet processing nozzle 10 is generated in the ejection material take-out tube 61 by the suction force generated inside the jet processing nozzle 10. At this time, the outside air is sucked from the outside air introduction pipe 63. That is, a state in which the external airflow is injected is formed at the front end of the outside air introducing pipe 63. By this air flow, an air flow toward the ejection material suction port 11a is generated in the vicinity of the right end of the ejection material take-out tube 61. The ejection material stored in the hopper 50 is taken up by the airflow, sucked into the ejection material take-out tube 61, and transferred to the ejection processing nozzle 10.
外氣導入管63只要至少其前端位於噴射材料取出管61之中即可。因此，外氣導入管63亦可設定為其外徑小於噴射材料取出管61之內徑之圓管。或者，外氣導入管63亦可設定為其外徑大於噴射材料取出管61之內徑，且設置有其前端以小於噴射材料取出管61之內徑之方式連續地縮徑之部位之形狀。於後者之構成中，藉由調整外氣導入管63之左右位置，可調整外氣導入管63之外壁與噴射材料取出管61之內壁之間隙。藉由變更該間隙之大小，可變更抽吸至噴射材料取出管61之噴射材料之量。若該間隙過寬，則無法穩定地將噴射材料抽吸至噴射材料取出管61，故而來自噴射加工用噴嘴10之噴射量不穩定。即無法進行穩定之噴射加工。又，若該間隙過窄，則阻礙噴射材料通過該間隙。藉由該間隙之調整，可調整移送至噴射加工用噴嘴10之噴射材料之量(噴射材料相對於壓縮空氣之混合比)，故而可藉由操作外氣導入管63，來調整噴射加工之能力。 The outside air introducing pipe 63 may be located at least at its tip end in the injection material take-out pipe 61. Therefore, the external air introduction pipe 63 can also be set to a circular pipe whose outer diameter is smaller than the inner diameter of the injection material take-out pipe 61. Alternatively, the outside air introduction pipe 63 may be set to have an outer diameter larger than the inner diameter of the injection material take-out pipe 61, and provided with a shape in which the front end thereof is continuously reduced in diameter so as to be smaller than the inner diameter of the spray material take-out pipe 61. In the latter configuration, by adjusting the left and right positions of the outside air introducing pipe 63, the gap between the outer wall of the outside air introducing pipe 63 and the inner wall of the injection material take-out pipe 61 can be adjusted. By changing the size of the gap, the amount of the ejection material sucked into the ejection material take-out tube 61 can be changed. When the gap is too wide, the ejection material cannot be stably sucked into the ejection material take-out tube 61, so that the ejection amount from the ejection processing nozzle 10 is unstable. That is, stable injection processing cannot be performed. Moreover, if the gap is too narrow, the ejection material is prevented from passing through the gap. By adjusting the gap, the amount of the ejection material (the mixing ratio of the ejection material to the compressed air) transferred to the ejection processing nozzle 10 can be adjusted, so that the ability of the ejection processing can be adjusted by operating the external air introduction tube 63. .
噴射材料取出管61經由噴射管與噴射加工用噴嘴10之噴射材料 抽吸口11a連接。噴射管因噴射材料之通過而受到磨耗，故而本實施形態之噴射加工裝置1具備噴射管之更換機構。具體而言，噴射材料取出管61至噴射材料抽吸口11a之路徑係由噴射管H1、H2及裝卸自由地連接於噴射管H1、H2之連接管C所構成。連接管C係以與噴射管H1、H2之連接部分別位於噴射加工室R內外之方式固定於下部外殼22。噴射材料取出管61與位於噴射加工室R外之連接管C之連接部藉由噴射管H1而連接。噴射材料抽吸口11a與位於噴射加工室R內之連接管C之連接部藉由噴射管H2而連接。藉由該構成，噴射管H1、H2之更換藉由作業人員打開上部外殼21，或者作業人員經由外框23之開口部23a接近噴射管H1、H2，僅於噴射加工裝置1之正面便可進行。 The injection material take-out pipe 61 is connected to the injection material suction port 11a of the injection processing nozzle 10 via an injection pipe. Since the injection pipe is worn by the passage of the injection material, the injection processing apparatus 1 of the present embodiment is provided with a replacement mechanism of the injection pipe. Specifically, the path from the injection material take-out pipe 61 to the injection material suction port 11a is constituted by the injection pipes H 1 and H 2 and the connection pipe C that is detachably connected to the injection pipes H 1 and H 2 . The connecting pipe C is fixed to the lower casing 22 such that the connection portions with the injection pipes H 1 and H 2 are located inside and outside the injection processing chamber R, respectively. Material is removed outside the injection tube 61 is connected with the processing chamber at the ejection tube C of the connecting portion R by H 1 is connected to the injection tube. Spray material suction port 11a is connected to the connecting portion positioned within the process chamber connected to the injection tube C R of the injection tube by H 2. With this configuration, the injection tube H 1, H 2 of the replacement worker by opening the upper housing 21, or the operator through the opening 23a of the outer frame 23 close to the ejection tube H 1, H 2, only 1 of the blasting machine It can be done on the front.
又，於噴射材料抽吸口11a固定有用以裝卸自由地連接噴射加工用噴嘴10之更換機構(未圖示)。本實施形態之更換機構使軟管聯接頭固定於噴射材料抽吸口11a。或者，亦可於噴射材料抽吸口11a及噴射管H2之前端分別固定有管接頭(例如耦合器)。藉由設置噴射加工用噴嘴10之更換機構，噴射加工用噴嘴10之更換變得容易。噴射加工室R因前方開放，故噴射加工用噴嘴10之更換僅於噴射加工裝置1之正面便可進行。藉由該構成，噴射加工用噴嘴10之磨耗之確認亦僅於噴射加工裝置1之正面便可進行。 Further, a replacement mechanism (not shown) for detachably connecting the jet processing nozzles 10 to the ejection material suction port 11a is fixed. The changing mechanism of the present embodiment fixes the hose coupling head to the ejection material suction port 11a. Alternatively, a pipe joint (for example, a coupler) may be fixed to the injection material suction port 11a and the front end of the injection pipe H 2 , respectively. By providing the replacing mechanism of the jet processing nozzle 10, the replacement of the jet processing nozzle 10 is facilitated. Since the jet processing chamber R is opened at the front, the replacement of the jet processing nozzle 10 can be performed only on the front surface of the jet processing apparatus 1. With this configuration, the abrasion of the jet processing nozzle 10 can be confirmed only on the front side of the jet processing apparatus 1.
又，於基台70，如圖1(A)所示，可固定有縱剖面呈字狀之加高基底71。於設置噴射加工裝置時，藉由加高基底71可容易地利用堆高機等移動該噴射加工裝置。 Moreover, in the base 70, as shown in FIG. 1(A), a longitudinal section can be fixed. The base of the font is raised 71. When the jet processing apparatus is provided, the jet processing apparatus can be easily moved by the stacker or the like by raising the base 71.
(噴射加工方法) (jet processing method)
其次，對藉由本實施形態之噴射加工裝置1而實施之噴射加工方法進行說明。 Next, a jet processing method performed by the jet processing apparatus 1 of the present embodiment will be described.
對操作面板P進行操作，使抽吸機構40作動，對噴射加工室R內進行抽吸。其次，解開閂鎖25，打開上部外殼21。其次，將特定量之 噴射材料投入至噴射加工室R，經由分級機構30將噴射材料移送至儲存進料斗50。其後，關閉上部外殼21，藉由閂鎖25進行鎖定而將上部外殼21與下部外殼22固定。藉此，形成作為封閉空間之噴射加工室R。噴射加工室R因受到抽吸機構40抽吸故成為負壓，外氣自作業部21c流入至噴射加工室R內。 The operation panel P is operated to operate the suction mechanism 40 to suction the inside of the injection processing chamber R. Next, the latch 25 is released and the upper casing 21 is opened. Second, the specific amount will be The ejection material is supplied to the ejection processing chamber R, and the ejection material is transferred to the storage hopper 50 via the classification mechanism 30. Thereafter, the upper casing 21 is closed, and the upper casing 21 and the lower casing 22 are fixed by locking by the latch 25. Thereby, the jet processing chamber R as a closed space is formed. The injection processing chamber R is suctioned by the suction mechanism 40 to become a negative pressure, and the outside air flows into the injection processing chamber R from the working portion 21c.
作業人員戴上手套，自作業部21c將手***，握持噴射加工用噴嘴10。其次，使上述腳踏開關「ON」，將包含噴射材料之氣固兩相流自噴射口13a噴射。此時，操作配置於噴射加工裝置1之前面之壓力調整閥V，以使其成為特定之噴射壓力之方式利用配置於噴射加工裝置1之前面之壓力計一面確認一面調整，之後使上述腳踏開關「OFF」而停止噴射材料之噴射，將手拔出。 The worker puts on the glove, inserts the hand from the working portion 21c, and holds the jet processing nozzle 10. Next, the foot switch is turned "ON", and the gas-solid two-phase flow including the injection material is ejected from the ejection port 13a. At this time, the pressure regulating valve V disposed in front of the jet processing apparatus 1 is operated so as to be adjusted by the pressure gauge disposed in front of the jet processing apparatus 1 so as to be a specific injection pressure, and then the pedal is adjusted. When the switch is "OFF", the ejection of the ejection material is stopped, and the hand is pulled out.
其次，解開閂鎖25，打開上部外殼21，將工件載置於加工板26上。其後，關閉上部外殼21，藉由閂鎖25進行鎖定而將上部外殼21與下部外殼22固定。 Next, the latch 25 is released, the upper casing 21 is opened, and the workpiece is placed on the processing board 26. Thereafter, the upper casing 21 is closed, and the upper casing 21 and the lower casing 22 are fixed by locking by the latch 25.
對操作面板P進行操作，作業人員自作業部21c將手***而握持噴射加工用噴嘴10及工件，之後使腳踏開關「ON」，將氣固兩相流自噴射口13a噴射。然後，介隔手套，由作業人員親自將工件對著噴射口13a進行掃描，藉此進行工件之研磨。此時，噴射加工室R內成為負壓，故而包含噴射材料之粉粒體(噴射材料及粉塵)不會自噴射加工室R漏出至外部。 When the operation panel P is operated, the operator inserts the hand from the working unit 21c to hold the injection processing nozzle 10 and the workpiece, and then turns the foot switch "ON" to eject the gas-solid two-phase flow from the ejection port 13a. Then, the glove is interposed, and the workpiece is manually scanned by the worker against the ejection opening 13a, thereby polishing the workpiece. At this time, since the inside of the injection processing chamber R becomes a negative pressure, the powder or granules (injection material and dust) containing the injection material do not leak from the injection processing chamber R to the outside.
噴射加工之情況可自設置於前面側斜面之觀察窗21a進行觀察。又，於頂面設置有採光窗21b，故而即便於噴射加工室R內不設置投光機亦可觀察到噴射加工室R。 The case of the jet processing can be observed from the observation window 21a provided on the front side slope. Further, since the lighting window 21b is provided on the top surface, the ejection processing chamber R can be observed even if the light projector is not provided in the ejection processing chamber R.
自噴射口13a噴射之包含噴射材料之粉粒體藉由抽吸機構40之抽吸力而移送至分級機構30。於分級機構30中，分離成可再使用之噴射材料與粉塵。詳細而言，藉由抽吸機構40之抽吸力，分級機構30內成 為負壓，又，於整流部31b產生一面回旋一面朝向分級構件32之氣流。首先，藉由該負壓，包含噴射材料之粉粒體自投入構件34投入至分級機構30內。到達整流部31b之包含噴射材料之粉粒體藉由整流部31b中所產生之氣流，一面回旋一面朝著分級構件32前進。然後，到達分級構件32之噴射材料中，重量較重之可再使用之噴射材料藉由重力而下落，貯存於位於下方之儲存進料斗50。移送至儲存進料斗50之可再使用之噴射材料藉由噴射材料移送機構60移送至噴射加工用噴嘴10，再次自噴射口13a噴射。另一方面，重量較輕之粉塵被抽吸至抽吸機構40，並被捕獲於抽吸機構本體41內之過濾器。 The powder or granule containing the injection material sprayed from the ejection opening 13a is transferred to the classification mechanism 30 by the suction force of the suction mechanism 40. In the classifying mechanism 30, it is separated into reusable spray materials and dust. In detail, the classification mechanism 30 is formed by the suction force of the suction mechanism 40. In the negative pressure, the flow portion of the rectifying portion 31b that is swirled toward the classifying member 32 is generated. First, by this negative pressure, the powder or granule containing the injection material is introduced into the classification mechanism 30 from the input member 34. The powder or granule containing the injection material that has reached the rectifying portion 31b advances toward the classifying member 32 while being swirled by the airflow generated in the rectifying portion 31b. Then, among the spray materials reaching the classifying member 32, the heavier reusable spray material falls by gravity and is stored in the storage hopper 50 located below. The reusable ejection material transferred to the storage hopper 50 is transferred to the ejection processing nozzle 10 by the ejection material transfer mechanism 60, and is ejected again from the ejection opening 13a. On the other hand, the lighter weight dust is sucked to the suction mechanism 40 and trapped in the filter inside the suction mechanism body 41.
於向工件噴射氣固兩相流特定之時間之後，使上述腳踏開關「OFF」，停止氣固兩相流之噴射，將手拔出。其後，解開閂鎖25，打開上部外殼21，回收工件。除去附著於該工件之噴射材料及粉塵，一系列噴射加工完成。 After the gas-solid two-phase flow is ejected to the workpiece for a specific period of time, the foot switch is turned "OFF" to stop the injection of the gas-solid two-phase flow, and the hand is pulled out. Thereafter, the latch 25 is released, the upper casing 21 is opened, and the workpiece is recovered. The spray material and dust adhering to the workpiece are removed, and a series of jet processing is completed.
若捕獲於抽吸機構本體41內之過濾器之粉塵堆積有特定量而導致抽吸能力降低，則停止氣固兩相流之噴射及抽吸機構40之作動，之後作業人員經由外框23之開口部23a接近位於噴射加工裝置1之前面之開閉扉41a，打開開閉扉41a卸下過濾器，而進行過濾器之清掃。粉塵之堆積狀況亦可於抽吸機構本體41安裝差壓計，而藉由其值進行管理，亦可為於1日之作業結束之後，進行過濾器之清掃之程度之管理。 If the dust accumulated in the filter trapped in the suction mechanism body 41 is accumulated in a certain amount to cause a decrease in the suction capacity, the injection of the gas-solid two-phase flow and the operation of the suction mechanism 40 are stopped, and then the worker passes through the outer frame 23 The opening 23a is close to the opening and closing port 41a located on the front surface of the jet processing apparatus 1, and the opening/closing port 41a is opened to remove the filter, and the filter is cleaned. The dust accumulation state can also be installed in the suction mechanism main body 41 by the differential pressure gauge, and the value can be managed, and the degree of cleaning of the filter can be managed after the completion of the work on the 1st day.
於為變更噴射材料、或清掃噴射加工裝置1而必須將噴射材料自噴射加工裝置1排出之情形時，於上部外殼21及下部外殼22固定之狀態下，作業人員經由外框23之開口部23a接近封閉栓52，卸下封閉栓52，將儲存進料斗50內之噴射材料排出，然後再次將封閉栓52嵌著於噴射材料排出構件51之開口。然後，將噴射壓縮空氣之噴嘴(未圖示)自作業部21c***，進行因空氣流而附著於噴射加工室R內之噴射材料 及粉塵之除去、以及噴射材料從利用上述腳踏開關自噴射加工用噴嘴10噴射之噴射材料之路徑之除去。藉由重複該作業，可將噴射加工裝置1內之噴射材料完全排出。 When it is necessary to discharge the injection material from the jet processing apparatus 1 in order to change the ejection material or to clean the jet processing apparatus 1, the operator passes through the opening 23a of the outer frame 23 while the upper casing 21 and the lower casing 22 are fixed. As close to the closing pin 52, the closing pin 52 is removed, the ejection material stored in the feeding hopper 50 is discharged, and the closing pin 52 is again fitted into the opening of the ejection material discharging member 51. Then, a nozzle (not shown) that ejects compressed air is inserted from the working portion 21c, and the ejection material adhered to the ejection processing chamber R by the air flow is performed. The removal of the dust and the removal of the ejection material from the path of the ejection material ejected from the ejection processing nozzle 10 by the above-described foot switch. By repeating this operation, the ejection material in the jet processing apparatus 1 can be completely discharged.
於變更包含於氣固兩相流之噴射材料之量(混合比)之情形時，只要自噴射加工裝置1之前面(外框23之開口部23a)操作噴射材料移送機構60之外氣導入管63即可。 In the case of changing the amount (mixing ratio) of the spray material contained in the gas-solid two-phase flow, the gas introduction pipe is operated from the front surface of the injection processing device 1 (the opening portion 23a of the outer frame 23) to the injection material transfer mechanism 60. 63 can be.
噴射管H1、H2伴隨使用而受到磨耗。於噴射管H1、H2磨耗之情形時，可藉由將噴射管H1、H2自噴射加工裝置1之前面卸下，安裝新的噴射管H1、H2進行更換。即，可藉由作業人員打開上部外殼21，或者作業人員經由外框23之開口部23a接近噴射管H1、H2而實現。 The injection pipes H 1 and H 2 are worn together with use. When the injection pipes H 1 and H 2 are worn out, the injection pipes H 1 and H 2 can be removed from the front surface of the jet processing apparatus 1 and the new injection pipes H 1 and H 2 can be replaced and replaced. That is, it can be realized by the operator opening the upper casing 21 or by the worker approaching the injection pipes H 1 and H 2 via the opening 23a of the outer frame 23.
由於噴射加工，噴射材料及粉塵附著於上部外殼21之觀察窗21a及採光窗21b。本實施形態之噴射加工室R可前面側開放，故而僅自噴射加工裝置1之正面便可清掃觀察窗21a及採光窗21b。 The ejection material and the dust adhere to the observation window 21a of the upper casing 21 and the lighting window 21b due to the blast processing. Since the injection processing chamber R of the present embodiment can be opened to the front side, the observation window 21a and the lighting window 21b can be cleaned only from the front surface of the jet processing apparatus 1.

Maintenance such as inspection and replacement of the spray processing nozzle 10, cleaning of the spray processing chamber R, commissioning of the classification mechanism, cleaning and replacement of the filter of the suction mechanism 40, discharge of the spray material from the storage feed hopper 50, and injection tube H 1 , replacement of H 2 , etc. In the jet processing apparatus 1, it is not necessary to provide a space for maintenance around the front side. That is, in the jet processing apparatus 1, it is not necessary to provide a space for maintenance on the left side surface, the right side surface, or the back surface. Therefore, the jet processing apparatus 1 can be provided even if the space is small.
又，作為用以進行噴射加工中之操作及設定之區域之操作空間位於噴射加工裝置1之正面。噴射加工中之操作及設定例如有氣固兩相流之噴射壓力之調整、噴射加工之情況之觀察、抽吸機構之作動、氣固兩相流之噴射、工件之掃描、噴射材料之混合比之設定等。於噴射加工裝置1中，無需於正面以外之周圍設置用於操作之空間。即，於噴射加工裝置1中，無需於其左側面、右側面、或背面設置用於操 作之空間。因此，即便空間狹小亦可設置噴射加工裝置1。 Further, an operation space serving as an area for performing an operation and setting in the ejection processing is located on the front surface of the jet processing apparatus 1. The operation and setting in the injection processing are, for example, the adjustment of the injection pressure of the gas-solid two-phase flow, the observation of the injection processing, the actuation of the suction mechanism, the injection of the gas-solid two-phase flow, the scanning of the workpiece, and the mixing ratio of the injection materials. Settings, etc. In the jet processing apparatus 1, it is not necessary to provide a space for operation around the front side. That is, in the jet processing apparatus 1, it is not necessary to provide for operation on the left side, the right side, or the back side thereof. Space for work. Therefore, the jet processing apparatus 1 can be provided even if the space is small.
其次，對檢驗本形態之噴射加工裝置1所得之結果進行說明。 Next, the results obtained by testing the jet processing apparatus 1 of the present embodiment will be described.
作為噴射材料，使用氧化鋁系之粒子(新東工業股份有限公司製造：AF24)，作為類粉塵，使用氧化鋁系之微粒子(新東工業股份有限公司製造：WA # 800)。將以98%噴射材料、2%類粉塵之方式稱重並混合所得之粉粒體作為初始之粉粒體，並收容於儲存進料斗50，之後使噴射加工裝置1作動10min，噴射該粉粒體。 As the blasting material, alumina-based particles (manufactured by Shinto Industries Co., Ltd.: AF24) were used, and as the dust-like type, alumina-based fine particles (manufactured by Shinto Industries Co., Ltd.: WA #800) were used. The powder or granules weighed and mixed with 98% of the spray material and 2% of the dust were used as the initial powder and granules, and were stored in the storage hopper 50, and then the spray processing apparatus 1 was operated for 10 minutes to spray the powder. body.
於停止噴射加工裝置1之作動之後，將儲存進料斗50內之粉粒體回收。於利用網眼為0.500mm之篩將回收之粉粒體分級之後，對大徑粒子及微粒子各者之重量進行測定，算出以下內容而進行評價。 After the operation of the jet processing apparatus 1 is stopped, the powder or granules stored in the feed hopper 50 are recovered.

試驗係使整流部31b之前端面至位於與該前端面對向之位置之分級構件32之壁面之長度L2相對於整流部31b之長度L1之比(L2/L1)、及整流構件31之直徑D2相對於抽吸構件33之直徑D1之比(D2/D1)、以及整流部31b中之風量分別變化。將其結果記錄於表1中。 The test is a ratio (L2/L1) of the length L2 of the front end surface of the rectifying portion 31b to the wall surface of the classifying member 32 located at a position facing the front end with respect to the length L1 of the rectifying portion 31b, and the diameter D2 of the rectifying member 31. The ratio (D2/D1) with respect to the diameter D1 of the suction member 33 and the amount of wind in the rectifying portion 31b change, respectively. The results are reported in Table 1.
整流部31b之前端面至位於與該前端面對向之位置之分級構件32之壁面之長度L2相對於整流部31b之長度L1之比(L2/L1)為1.25~1.75，整流構件31之直徑D2相對於抽吸構件33之直徑D1之比(D2/D1)為1.50~2.00，及整流部31b中之風量為2.1~3.6m3/min之情形均為「△」或「○」評價(實施例1~8)。L2/L1或D2/D1相對較低之實施例1及4為「△」評價，該評價表示雖然分級性能稍差但只要將條件最佳化便會達到「○」評價之程度。因此，提示其可充分適用於噴射加工裝置。另一方面，風量不脫離2.1~3.6m3/min之情形均為「×」評價，判明分級性能較差(比較例1、2)。 The ratio (L2/L1) of the length L2 of the front end surface of the rectifying portion 31b to the wall surface of the classifying member 32 located at a position facing the front end with respect to the length L1 of the rectifying portion 31b is 1.25 to 1.75, and the diameter D2 of the rectifying member 31 The ratio (D2/D1) to the diameter D1 of the suction member 33 is 1.50 to 2.00, and the air volume in the rectifying unit 31b is 2.1 to 3.6 m 3 /min, which is evaluated as "△" or "○" (implementation) Example 1~8). Examples 1 and 4 in which L2/L1 or D2/D1 were relatively low were evaluated as "Δ", and this evaluation showed that although the classification performance was slightly inferior, the evaluation of "○" was achieved as long as the conditions were optimized. Therefore, it is suggested that it can be sufficiently applied to the jet processing apparatus. On the other hand, the case where the air volume did not deviate from 2.1 to 3.6 m 3 /min was evaluated as "X", and it was found that the classification performance was poor (Comparative Examples 1 and 2).
本實施形態之噴射加工裝置非常小型化，故而可將分級機構30、抽吸機構40、儲存進料斗50、噴射材料移送機構60配置於基台70與下部外殼22之間之空間。又，若如圖1(A)所示，於基台70之下表面固定加高基底71，則噴射加工裝置1之設置變得容易。其結果，與先前之噴射加工裝置相比，不僅對上述維護性及操作性有利，對設置性亦變得有利。 Since the jet processing apparatus of the present embodiment is extremely compact, the classification mechanism 30, the suction mechanism 40, the storage hopper 50, and the ejection material transfer mechanism 60 can be disposed in a space between the base 70 and the lower casing 22. Further, as shown in Fig. 1(A), when the base 71 is fixed to the lower surface of the base 70, the installation of the jet processing apparatus 1 becomes easy. As a result, compared with the prior art jet processing apparatus, not only the above-described maintainability and workability are advantageous, but also the mountability is also advantageous.
本實施形態之噴射加工裝置1之用於維護及操作之構成設置於裝置前面，故而可形成使複數台噴射加工裝置1複數台無間隙地並列配置之噴射加工裝置列。 Since the configuration of the jet processing apparatus 1 of the present embodiment for maintenance and operation is provided in front of the apparatus, it is possible to form an array of jet processing apparatuses in which a plurality of jet processing apparatuses 1 are arranged in parallel without any gaps.
