　しかしながら、この装置では、製品の側面側のみしかショット処理できないうえ、製品の搬入出時には投射ができないため処理待ち時間が生じる。 However, in this apparatus, only the side surface of the product can be shot, and a projection time cannot be projected when the product is carried in and out, resulting in a processing waiting time.
　本発明は、上記事実を考慮して、被処理対象物に対して上面側を含む広範囲でのショット処理が可能で、かつ被処理対象物の処理待ち時間を抑えることができるショット処理装置を得ることが目的である。 In view of the above facts, the present invention provides a shot processing apparatus capable of performing shot processing over a wide range including the upper surface side of the object to be processed and suppressing the processing waiting time of the object to be processed. Is the purpose.
　本発明のショット処理装置は、回転可能な第一回転テーブルと、前記第一回転テーブル上に複数配置され、前記第一回転テーブルの回転軸と平行な回転軸を備えて回転可能とされると共に、前記被処理対象物が載せられる第二回転テーブルと、前記第一回転テーブルの上方側に配置され、前記第一回転テーブル上の一部を投射領域として前記第二回転テーブル上の前記被処理対象物に対して投射材を遠心力で加速して投射する遠心式投射機と、を有する。 The shot processing apparatus according to the present invention includes a rotatable first rotary table, a plurality of the rotary tables arranged on the first rotary table, and is rotatable with a rotation axis parallel to the rotation axis of the first rotary table. The second turntable on which the object to be processed is placed and the part to be processed on the second turntable with a part on the first turntable as a projection area, which is disposed above the first turntable. And a centrifugal projector that projects the projection material by centrifuging the object with centrifugal force.
　本発明のショット処理装置によれば、回転可能な第一回転テーブル上には複数の第二回転テーブルが配置され、これらの第二回転テーブルは、第一回転テーブルの回転軸と平行な回転軸を備えて回転可能となっており、被処理対象物が載せられる。また、第一回転テーブルの上方側に配置された遠心式投射機は、第一回転テーブル上の一部を投射領域として第二回転テーブル上の被処理対象物に対して投射材を遠心力で加速して投射する。 According to the shot processing device of the present invention, a plurality of second rotary tables are arranged on a rotatable first rotary table, and these second rotary tables have a rotary axis parallel to the rotary axis of the first rotary table. Can be rotated, and the object to be processed is placed thereon. In addition, the centrifugal projector disposed on the upper side of the first rotary table has a part of the first rotary table as a projection area, and the projection material is applied to the object to be processed on the second rotary table by centrifugal force. Accelerate and project.
　このため、被処理対象物は、第一回転テーブルの回転に応じて変位しながら、遠心式投射機の下方側付近に配置されたときには主に上面側がショット処理され、遠心式投射機の下方側から離れた位置に配置されたときにはその位置に応じて主に側面側がショット処理される。また、投射材の投射中においても、第一回転テーブルの非投射領域の上に配置された第二回転テーブル上では被処理対象物を載せ降ろしすることができる。 For this reason, when the object to be processed is disposed near the lower side of the centrifugal projector while being displaced according to the rotation of the first rotary table, the upper surface side is mainly shot-processed, and the lower side of the centrifugal projector When it is arranged at a position away from the side, the side surface side is mainly shot-processed according to the position. In addition, even during the projection of the projection material, the object to be processed can be loaded and unloaded on the second rotary table disposed on the non-projection area of the first rotary table.
　いくつかの実施形態では、ショット処理装置は更に、複数の前記第二回転テーブルの下方側にそれぞれ配置され、前記第二回転テーブルの回転軸に設けられた巻掛部と、装置平面視で複数の前記巻掛部のすべてを包囲する位置に配置され、少なくとも前記投射領域の下方側を含む範囲で複数の前記巻掛部に巻き掛けられた無端状のベルトと、前記ベルトを回転駆動させる駆動機構と、を有する。なお、本願でベルトと言うときは、Ｖベルト、タイミングベルト、チェーン等の、公知の無端の動力伝達用部材を意味する。 In some embodiments, the shot processing device is further arranged on a lower side of each of the plurality of second rotary tables, and a plurality of winding portions provided on a rotation shaft of the second rotary table, and a plurality of the shot processing devices in a plan view of the device.

And a mechanism. Note that the belt in this application means a known endless power transmission member such as a V belt, a timing belt, or a chain.
　このように構成されたショット処理装置によれば、複数の第二回転テーブルの下方側にそれぞれ配置された巻掛部が第二回転テーブルの回転軸に設けられており、装置平面視で複数の巻掛部のすべてを包囲する位置には無端状のベルトが配置されている。このベルトは、少なくとも投射領域の下方側を含む範囲で複数の巻掛部に巻き掛けられており、駆動機構によって回転駆動させられる。このため、投射領域で第二回転テーブルが回転させられるので、簡易な構成でありながら被処理対象物の全周に亘ってむらなく均一にショット処理がなされる。 According to the shot processing apparatus configured as described above, the winding portions respectively disposed on the lower sides of the plurality of second rotary tables are provided on the rotation shaft of the second rotary table, and the plurality of the plurality of the rotary parts in a plan view of the apparatus. An endless belt is disposed at a position surrounding all the winding portions. The belt is wound around a plurality of winding portions in a range including at least the lower side of the projection area, and is driven to rotate by a driving mechanism. For this reason, since the second rotary table is rotated in the projection area, shot processing is performed uniformly over the entire circumference of the object to be processed even with a simple configuration.
　いくつかの実施形態では、ショット処理装置は更に、複数の前記巻掛部のうちのいずれかには前記ベルトが巻き掛けられず、複数の前記巻掛部のうち前記ベルトが巻き掛けられないものの位置は、前記投射領域から外れた非投射領域であってかつ前記被処理対象物が前記第二回転テーブルに載せ降ろしされる載せ降ろしゾーンの下方側に設定されている。好ましくは、複数の巻掛部に外接する仮想円の外側に設けた少なくとも１の補助巻掛部によって、複数の巻掛部のうちのいずれかに前記ベルトが巻き掛けられないように構成されている。 In some embodiments, the shot processing apparatus further includes: the belt is not wound on any one of the plurality of the winding portions; and the belt is not wound on the plurality of the winding portions. The position is a non-projection area outside the projection area, and is set below the loading / unloading zone where the object to be processed is loaded / unloaded on the second rotary table. Preferably, the belt is not wound around any of the plurality of winding portions by at least one auxiliary winding portion provided outside the virtual circle circumscribing the plurality of winding portions. Yes.
　このように構成されたショット処理装置によれば、複数の巻掛部のうちのいずれかにはベルトが巻き掛けられておらず、複数の巻掛部のうちベルトが巻き掛けられないものの位置は、投射領域から外れた非投射領域であってかつ被処理対象物が第二回転テーブルに載せ降ろしされる載せ降ろしゾーンの下方側に設定されているので、載せ降ろしゾーンでは第二回転テーブルの回転軸回りでの回転（自転）が停止される。このため、簡易な構成でありながら、第二回転テーブルを自転させない状態で被処理対象物の載せ降ろしができる。 According to the shot processing apparatus configured as described above, no belt is wound around any of the plurality of winding portions, and the position of the plurality of winding portions where the belt is not wound is Since the non-projection area deviated from the projection area is set below the loading / unloading zone where the object to be processed is loaded / unloaded on the second rotation table, the rotation of the second rotation table is performed in the loading / unloading zone. The rotation (spinning) around the axis is stopped. For this reason, although it is a simple structure, the to-be-processed target object can be loaded and unloaded in a state where the second rotary table is not rotated.
　以上説明したように、本発明に係るショット処理装置によれば、被処理対象物に対して上面側を含む広範囲でのショット処理が可能で、かつ被処理対象物の処理待ち時間を抑えることができるという優れた効果を有する。 As described above, according to the shot processing apparatus of the present invention, it is possible to perform shot processing over a wide range including the upper surface side of the object to be processed, and to suppress the processing waiting time of the object to be processed. It has an excellent effect of being able to.

In addition, a loading / unloading port 14 </ b> A for loading / unloading the object 12 to be processed is formed in the cabinet 14.
　また、キャビネット１４の搬入出口１４Ａには、その上端部にシール体４０が取り付けられている。シール体４０には、樹脂等の弾力性が高い（所謂コシが強い）材料が適用されている。シール体４０は、可撓性を備えた複数の長尺材で構成され（所謂ゴム暖簾とされ）、被処理対象物１２の通過時に被処理対象物１２の搬送方向に撓むように設定されている。これにより、シール体４０は、投射材がキャビネット１４の搬入出口１４Ａから漏れ出す（飛散する）のを阻止するようになっている。 In addition, a seal body 40 is attached to the loading / unloading port 14A of the cabinet 14 at its upper end. A material having high elasticity (so-called strong stiffness) such as resin is applied to the seal body 40. The seal body 40 is composed of a plurality of long materials having flexibility (so-called rubber warming), and is set to bend in the transport direction of the object to be processed 12 when the object to be processed 12 passes. . Thereby, the sealing body 40 prevents the projection material from leaking out (scattering) from the loading / unloading port 14 </ b> A of the cabinet 14.
　キャビネット１４内には、被処理対象物１２が載置される製品載置部１８が設けられている。なお、製品載置部１８については詳細後述する。キャビネット１４内の天井部側には、遠心式投射機２０が設けられている。遠心式投射機２０は、羽根車（インペラ）の回転により投射材（ショット、本実施形態では一例として鋼球）に遠心力を付与することが可能となっている。すなわち、遠心式投射機２０は、投射材を遠心力で加速して、投射室１６の被処理対象物１２に対して投射するようになっている（図６参照）。 In the cabinet 14, a product placement unit 18 on which the object 12 to be processed is placed is provided.

　図２に示されるように、バケットエレベータ２６Ｃは、公知構造であるため詳細説明を省略する。簡単に説明すると、ショットブラスト装置１０の上部及び下部に配置されたプーリ２６Ｃ１（図２では上側のみ図示）に無端ベルト２６Ｃ２が巻き掛けられると共に、無端ベルト２６Ｃ２に多数のバケット（図示省略）が取り付けられている。またプーリ２６Ｃ１は駆動力伝達手段（無端のベルト等）を介して駆動用モータに接続されて回転駆動可能とされている。これにより、バケットエレベータ２６Ｃは、スクリュウコンベヤ２６Ｂで回収した（一時貯留された）投射材を前記バケットで掬い上げると共に、プーリ２６Ｃ１を駆動用モータで回転させることによって、バケット内の投射材をキャビネット１４の上方側へ向けて搬送するようになっている。 As shown in FIG. 2, the bucket elevator 26C has a well-known structure, and a detailed description thereof will be omitted. Briefly, an endless belt 26C2 is wound around a pulley 26C1 (only the upper side is shown in FIG. 2) arranged at the upper and lower portions of the shot blasting apparatus 10, and a number of buckets (not shown) are attached to the endless belt 26C2. It has been. The pulley 26C1 is connected to a driving motor via a driving force transmission means (endless belt or the like) so as to be rotationally driven. As a result, the bucket elevator 26C scoops up the projection material collected (temporarily stored) by the screw conveyor 26B with the bucket and rotates the pulley 26C1 with the drive motor, so that the projection material in the bucket is moved to the cabinet 14. It conveys toward the upper side of the.
　また、図１に示されるように、バケットエレベータ２６Ｃの上部側の近傍には、セパレータ２６Ｅが配置されている。セパレータ２６Ｅは、投射材タンク２６Ｆに連通しており、バケットエレベータ２６Ｃで搬送された投射材のうち適正な投射材のみを投射材タンク２６Ｆへ流すようになっている。投射材タンク２６Ｆは、投射材供給用のタンクであり、流量調整ゲート２４の上方側に配置されている。 Further, as shown in FIG. 1, a separator 26E is disposed in the vicinity of the upper side of the bucket elevator 26C. The separator 26E communicates with the projection material tank 26F, and only the appropriate projection material among the projection materials conveyed by the bucket elevator 26C is allowed to flow to the projection material tank 26F. The projection material tank 26 </ b> F is a tank for supplying the projection material, and is disposed above the flow rate adjustment gate 24.
　また、図２に示されるように、セパレータ２６Ｅの下部は、装置上下方向に延びるパイプ２８Ｄに接続されており、パイプ２８Ｄの下端開口の下方側には、粗受け箱２８Ｅが配置されている。すなわち、セパレータ２６Ｅにより分離された粗粉が粗受け箱２８Ｅ内に入るようになっている。 As shown in FIG. 2, the lower portion of the separator 26E is connected to a pipe 28D extending in the vertical direction of the apparatus, and a rough receiving box 28E is disposed below the lower end opening of the pipe 28D. That is, the coarse powder separated by the separator 26E enters the coarse receiving box 28E.
　一方、図１に示されるように、キャビネット１４の側部には、ベンチレータ２８Ａ（換気装置）が配置されている。また、キャビネット１４の天井部には吸出口部１４Ｅが形成されている。この吸出口部１４Ｅにはダクト２８Ｃが接続されており、キャビネット１４の内部に発生した粉塵がキャビネット１４の吸出口部１４Ｅから吸引されるようになっている。図２及び図３に示されるように、ダクト２８Ｃには集塵機２８Ｂが接続されている。集塵機２８Ｂは、ダクト２８Ｃを経た空気中の粉塵を濾過して空気のみを装置外に排出する。 On the other hand, as shown in FIG. 1, a ventilator 28 </ b> A (ventilator) is disposed on the side of the cabinet 14. A suction port 14 </ b> E is formed on the ceiling of the cabinet 14. A duct 28 </ b> C is connected to the suction port 14 </ b> E so that dust generated inside the cabinet 14 is sucked from the suction port 14 </ b> E of the cabinet 14. As shown in FIGS. 2 and 3, a dust collector 28B is connected to the duct 28C. The dust collector 28B filters the dust in the air that has passed through the duct 28C and discharges only the air out of the apparatus.

It is shown. FIG. 6 is a schematic perspective view for explaining the positional relationship between the centrifugal projector 20, a later-described large table 30, and a small table 32.
　図６に示されるように、製品載置部１８には、第一回転テーブルとしての大テーブル３０が配置されると共に、大テーブル３０上には大テーブル３０の同心円上の位置に複数の（本実施形態では六個の）第二回転テーブルとしての小テーブル３２が周方向に等間隔で配置されている。すなわち、製品載置部１８は、所謂マルチテーブルの構造になっている。 As shown in FIG. 6, a large table 30 as a first rotary table is disposed on the product placement unit 18, and a plurality of (books) are arranged on the large table 30 at positions on concentric circles of the large table 30. In the embodiment, six small tables 32 as second rotating tables are arranged at equal intervals in the circumferential direction. That is, the product mounting portion 18 has a so-called multi-table structure.
　大テーブル３０は、装置上下方向の回転軸３１回りに回転（公転）可能とされており、遠心式投射機２０により投射材が投射される投射領域Ｘと、投射領域Ｘ以外の非投射領域とを含む位置に配置されている。換言すれば、遠心式投射機２０は、大テーブル３０の上方側に配置され、大テーブル３０上の一部を投射領域Ｘとしている。また、小テーブル３２は、大テーブル３０よりも小径とされると共に、大テーブル３０の回転軸３１と平行な回転軸３３を備えて回転（自転）可能とされ、被処理対象物１２が載せられる。小テーブル３２上の被処理対象物１２に対しては、遠心式投射機２０が投射材を遠心力で加速して投射するようになっている。各小テーブル３２は、大テーブル３０の回転軸３１を中心とする円周上に配置されており、大テーブル３０が回転したとき、小テーブル３２は回転軸３１の回りを周回して、投射領域Ｘを通過する。 The large table 30 can be rotated (revolved) around the rotation axis 31 in the vertical direction of the apparatus, and the projection area X onto which the projection material is projected by the centrifugal projector 20 and a non-projection area other than the projection area X It is arranged at a position including In other words, the centrifugal projector 20 is disposed on the upper side of the large table 30, and a part of the large table 30 is used as the projection area X. The small table 32 has a diameter smaller than that of the large table 30 and is provided with a rotation shaft 33 parallel to the rotation shaft 31 of the large table 30 so that the small table 32 can be rotated (spinned). . The centrifugal projector 20 accelerates the projection material with centrifugal force and projects the object 12 to be processed 12 on the small table 32. Each small table 32 is arranged on a circumference centering on the rotation axis 31 of the large table 30, and when the large table 30 rotates, the small table 32 circulates around the rotation axis 31 to generate a projection area. Pass through X.
　図４に示されるように、大テーブル３０の回転軸３１の下端部は軸受部３４を介してベース部３６上に配置されている。また、大テーブル３０の外周側面（図中の右側面参照）は、プーリ（フリクションプーリ）４２に接している。プーリ４２の軸４３の軸線方向は、大テーブル３０の回転軸３１の軸線方向と平行とされている。また、プーリ４２の軸４３は、軸受４４に回転自在に支持されると共に、減速機を介して駆動モータ４６（図４ではブロック化して示す、図３参照）に接続されている。すなわち、大テーブル３０は、駆動モータ４６が回転駆動することでプーリ４２等を介して回転駆動されるようになっている。なお、図１及び図３に示されるように、駆動モータ４６は、キャビネット１４の天井部に配置されている。 As shown in FIG. 4, the lower end portion of the rotating shaft 31 of the large table 30 is disposed on the base portion 36 via the bearing portion 34. Further, the outer peripheral side surface (see the right side surface in the drawing) of the large table 30 is in contact with a pulley (friction pulley) 42. The axial direction of the shaft 43 of the pulley 42 is parallel to the axial direction of the rotary shaft 31 of the large table 30. The shaft 43 of the pulley 42 is rotatably supported by the bearing 44 and is connected to a drive motor 46 (shown in a block form in FIG. 4, see FIG. 3) via a speed reducer. That is, the large table 30 is rotationally driven via the pulley 42 and the like when the drive motor 46 is rotationally driven. As shown in FIGS. 1 and 3, the drive motor 46 is disposed on the ceiling of the cabinet 14.
　また、図４に示されるように、複数の小テーブル３２の下方側には、回転軸３３を回転可能に支持する軸受４８がそれぞれ設けられており、この軸受４８は、支持部材を介して大テーブル３０に取り付けられている。また、複数の小テーブル３２の下方側にはそれぞれ巻掛部としてのプーリ５０が小テーブル３２における回転軸３３の下端部に固着されている。プーリ５０は、回転軸３３と同軸に設けられている。 As shown in FIG. 4, bearings 48 that rotatably support the rotating shaft 33 are respectively provided below the plurality of small tables 32, and these bearings 48 are large via support members. It is attached to the table 30. A pulley 50 as a winding portion is fixed to the lower end portion of the rotating shaft 33 of the small table 32 on the lower side of the plurality of small tables 32. The pulley 50 is provided coaxially with the rotation shaft 33.
　図５に示されるように、装置平面視で複数のプーリ５０のすべてを包囲する位置には、無端状のＶベルト５２が配置されている。Ｖベルト５２は、遠心式投射機２０によって投射材が投射される投射領域Ｘの下方側を含む範囲で複数（本実施形態では図中右側の二個を除く計四個）のプーリ５０に巻き掛けられている。ここで、本実施形態では、複数のプーリ５０のうちのいずれか二個にはＶベルト５２が巻き掛けられていない。複数のプーリ５０のうちＶベルト５２が巻き掛けられないものの位置は、投射領域Ｘから外れた非投射領域であってかつ被処理対象物１２が小テーブル３２に載せ降ろしされる載せ降ろしゾーン６２（搬入出口１４Ａである図中右側）の下方側に設定されている。 As shown in FIG. 5, an endless V-belt 52 is disposed at a position surrounding all of the plurality of pulleys 50 in a plan view of the apparatus. The V belt 52 is wound around a plurality of pulleys 50 (a total of four except the two on the right side in the figure in the present embodiment) in a range including the lower side of the projection area X onto which the projection material is projected by the centrifugal projector 20. It is hung. Here, in this embodiment, the V belt 52 is not wound around any two of the plurality of pulleys 50. Of the plurality of pulleys 50, the position where the V-belt 52 is not wound is a non-projection area deviated from the projection area X, and the loading / unloading zone 62 (the workpiece 12 is loaded onto and unloaded from the small table 32). It is set on the lower side of the loading / unloading port 14A (right side in the figure).
　Ｖベルト５２は、複数のプーリ５０の他、キャビネット１４（図１参照）側に設けられ
た複数の小プーリ５４及び駆動プーリ５６に巻き掛けられている。複数の小プーリ５４及び駆動プーリ５６は、複数のプーリ５０に外接する仮想円の外側に位置する。駆動プーリ５６は駆動モータ５８に接続されている。駆動モータ５８が回転駆動された状態では、Ｖベルト５２が回転駆動されることによってこのＶベルト５２に巻き掛けられたプーリ５０（ひいてはそのプーリ５０が設けられた小テーブル３２）が回転するようになっている。なお、駆動プーリ５６及び駆動モータ５８は、Ｖベルト５２を回転駆動させる駆動機構６０を構成している。また、複数の小プーリ５４及び駆動プーリ５６が補助巻掛部を構成する。なお、複数の小プーリ５４を用いずに、駆動プーリ５６のみで載せ降しゾーン６２の下方側でプーリ５０にＶベルト５２を巻き掛けない構成にすることもできる。 The V belt 52 is wound around a plurality of small pulleys 54 and a drive pulley 56 provided on the cabinet 14 (see FIG. 1) side in addition to the plurality of pulleys 50. The plurality of small pulleys 54 and the drive pulley 56 are located outside the virtual circle circumscribing the plurality of pulleys 50. The drive pulley 56 is connected to a drive motor 58. In a state where the drive motor 58 is rotationally driven, the pulley 50 wound around the V-belt 52 (and thus the small table 32 provided with the pulley 50) is rotated by rotating the V-belt 52. It has become. The drive pulley 56 and the drive motor 58 constitute a drive mechanism 60 that drives the V belt 52 to rotate. Further, the plurality of small pulleys 54 and the drive pulley 56 constitute an auxiliary winding part. Instead of using a plurality of small pulleys 54, it is also possible to adopt a configuration in which only the drive pulley 56 is mounted and the V belt 52 is not wound around the pulley 50 below the zone 62.
　（実施形態の作用・効果）
　次に、上記実施形態の作用及び効果について説明する。 (Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.
　図６に示されるように、上記構成のショットブラスト装置１０では、回転可能な大テーブル３０上には複数の小テーブル３２が配置され、これらの小テーブル３２は、大テーブル３０の回転軸３１と平行な回転軸３３を備えて回転可能となっており、被処理対象物１２が載せられる。また、大テーブル３０の上方側に配置された遠心式投射機２０は、大テーブル３０上の一部を投射領域Ｘとして小テーブル３２上の被処理対象物１２に対して投射材を遠心力で加速して投射する。 As shown in FIG. 6, in the shot blasting apparatus 10 having the above-described configuration, a plurality of small tables 32 are arranged on a rotatable large table 30, and these small tables 32 are connected to the rotary shaft 31 of the large table 30. A parallel rotation shaft 33 is provided for rotation, and the workpiece 12 is placed thereon. In addition, the centrifugal projector 20 disposed on the upper side of the large table 30 uses a centrifugal force to project the projection material with respect to the target object 12 on the small table 32 with a part on the large table 30 as a projection region X. Accelerate and project.
　このため、被処理対象物１２は、大テーブル３０の回転に応じて変位しながら、遠心式投射機２０の下方側付近に配置されたときには主に上面側がショット処理され、遠心式投射機２０の下方側から離れた位置に配置されたときにはその位置に応じて主に側面側がショット処理される。また、投射材の投射中においても、載せ降ろしゾーン６２（大テーブル３０の非投射領域上）に配置された小テーブル３２上では、被処理対象物１２を載せ降ろしすることができる。よって、遠心式投射機２０による連続投射が可能になる。 For this reason, when the object 12 to be processed is disposed near the lower side of the centrifugal projector 20 while being displaced according to the rotation of the large table 30, the upper surface side is mainly shot-processed. When it is arranged at a position away from the lower side, the side surface side is mainly shot-processed according to the position. Even during the projection of the projection material, the object 12 to be processed can be loaded / unloaded on the small table 32 arranged in the loading / unloading zone 62 (on the non-projection area of the large table 30). Therefore, continuous projection by the centrifugal projector 20 becomes possible.
　また、図４に示されるように、本実施形態に係るショットブラスト装置１０では、複数の小テーブル３２の下方側にそれぞれ配置されたプーリ５０が小テーブル３２の回転軸３３に固着されており、図５に示されるように、装置平面視で複数のプーリ５０のすべてを包囲する位置には無端状のＶベルト５２が配置されている。このＶベルト５２は、遠心式投射機２０によって投射材が投射される投射領域Ｘの下方側を含む範囲で複数のプーリ５０に巻き掛けられており、駆動機構６０によって回転駆動させられる。このため、遠心式投射機２０によって投射材が投射される投射領域Ｘを含む範囲で小テーブル３２が回転させられるので、簡易な構成でありながら被処理対象物１２の全周に亘ってむらなく均一にショット処理がなされる。 Further, as shown in FIG. 4, in the shot blasting apparatus 10 according to the present embodiment, the pulleys 50 respectively disposed on the lower side of the plurality of small tables 32 are fixed to the rotating shaft 33 of the small table 32. As shown in FIG. 5, an endless V-belt 52 is arranged at a position surrounding all of the plurality of pulleys 50 in the apparatus plan view. The V-belt 52 is wound around a plurality of pulleys 50 in a range including the lower side of the projection area X on which the projection material is projected by the centrifugal projector 20, and is rotated by the drive mechanism 60. For this reason, since the small table 32 is rotated in the range including the projection area X on which the projection material is projected by the centrifugal projector 20, the entire periphery of the object 12 to be processed is uniformly distributed with a simple configuration. Shot processing is performed uniformly.
　ここで、複数のプーリ５０のうちのいずれか二個にはＶベルト５２が巻き掛けられておらず、複数のプーリ５０のうちＶベルト５２が巻き掛けられないものの位置は、投射領域Ｘから外れた非投射領域であってかつ被処理対象物１２が小テーブル３２に載せ降ろしされる載せ降ろしゾーン６２の下方側に設定されているので、載せ降ろしゾーン６２では小テーブル３２の回転軸３３回りでの回転（自転）が停止される。このため、簡易な構成でありながら、小テーブル３２を自転させない状態で被処理対象物１２の載せ降ろしができる。より具体的には、大テーブル３０の回転速度は周速で５～３０ｍｍ／ｓと非常に遅いため、大テーブル３０が回転中であっても作業者による被処理対象物１２の小テーブル３２への乗せ降しを危険なく行なうことができる。また、その乗せ降しの際に前記投射領域Ｘにおける前記小テーブル３２上の被処理対象物１２に対して、前記遠心投射機２０から投射材を投射することにより、被処理対象物の処理待ち時間を抑えることが可能になる。 Here, the V belt 52 is not wound around any two of the plurality of pulleys 50, and the position of the plurality of pulleys 50 where the V belt 52 is not wound is out of the projection region X. In addition, since the non-projection area is set on the lower side of the loading / unloading zone 62 where the object 12 to be processed is loaded / unloaded on the small table 32, in the loading / unloading zone 62 around the rotation axis 33 of the small table 32. Rotation (rotation) is stopped. For this reason, although it is a simple structure, the to-be-processed target object 12 can be loaded and unloaded in a state where the small table 32 is not rotated. More specifically, since the rotation speed of the large table 30 is very slow at a peripheral speed of 5 to 30 mm / s, even when the large table 30 is rotating, the operator moves to the small table 32 of the object 12 to be processed. Can be loaded and unloaded without danger. In addition, the projection target is projected from the centrifugal projector 20 onto the processing target object 12 on the small table 32 in the projection area X at the time of getting on and off, thereby waiting for processing of the processing target object. Time can be saved.
　以上説明したように、本実施形態に係るショットブラスト装置１０によれば、被処理対象物１２に対して上面側を含む広範囲でショット処理が可能で、かつ被処理対象物１２の処理待ち時間を抑えることができる。 As described above, according to the shot blasting apparatus 10 according to the present embodiment, it is possible to perform shot processing in a wide range including the upper surface side with respect to the processing target object 12, and to reduce the processing waiting time of the processing target object 12. Can be suppressed.

　なお、上記実施形態では、図４に示されるように、巻掛部としてのプーリ５０が小テーブル３２の下端部に固着されているが、巻掛部は、例えば、第二回転テーブルの下方側で当該第二回転テーブルの回転軸に一体に形成された巻掛部であってもよい。 (Supplementary explanation of the embodiment)
In the above embodiment, as shown in FIG. 4, the pulley 50 as the winding portion is fixed to the lower end portion of the small table 32, but the winding portion is, for example, the lower side of the second rotary table. The winding part integrally formed in the rotating shaft of the said 2nd rotary table may be sufficient.
　また、上記実施形態では、図５に示されるように、小テーブル３２が無端状のＶベルト５２及び駆動機構６０によって回転させられているが、第二回転テーブルは、例えば、駆動モータがそれぞれ接続されて回転駆動及び回転の停止がされてもよい。 In the above embodiment, as shown in FIG. 5, the small table 32 is rotated by the endless V-belt 52 and the drive mechanism 60. However, for example, the drive motor is connected to the second rotary table. Then, the rotation drive and the rotation stop may be performed.
　また、上記実施形態では、載せ降ろしゾーン６２の下方側のプーリ５０にＶベルト５２が巻き掛けられない構成となっているが、例えば、すべての巻掛部（プーリ５０）にベルトが巻き掛けられると共に、第二回転テーブルの回転軸と巻掛部の間にクラッチ機構が設けられ、かつ、載せ降ろしゾーン以外ではクラッチ繋がれて巻掛部から第二回転テーブルの回転軸に動力が伝達されると共に、載せ降ろしゾーンではクラッチが切られて巻掛部から第二回転テーブルの回転軸への動力を遮断するような構成にしてもよい。 In the above embodiment, the V belt 52 is not wound around the pulley 50 below the loading / unloading zone 62. For example, the belt is wound around all the winding portions (pulleys 50). At the same time, a clutch mechanism is provided between the rotary shaft of the second rotary table and the winding portion, and the clutch is connected except for the loading / unloading zone, and power is transmitted from the winding portion to the rotary shaft of the second rotary table. At the same time, the clutch may be disengaged in the loading / unloading zone to cut off the power from the winding portion to the rotating shaft of the second rotary table.
　また、上記実施形態では、複数のプーリ５０のうちのいずれか二個にＶベルト５２が巻き掛けられていないが、例えば、複数のプーリ（５０）のうちのいずれか一個にＶベルト（５２）が巻き掛けられていない構成等にすることも可能である。 In the above embodiment, the V belt 52 is not wound around any two of the plurality of pulleys 50. For example, the V belt (52) is wound around any one of the plurality of pulleys (50). It is also possible to adopt a configuration in which no is wound.
　また、上記実施形態において、例えば、キャビネット（１４）の搬入出口（１４Ａ）側にエリアセンサを設けると共に、前記エリアセンサから人体の存在を示す検知信号が入力されたときに制御部が大テーブル（３０）の回転を一時停止させるように駆動モータ（４６）を制御するような構成を適用することが可能である。また、例えば、第一回転テーブルを第二回転テーブルの配置に応じて設定された回転角度刻みで第一回転テーブルの回転軸回りに回転させる割出装置を第一回転テーブルの回転駆動用に設けるような構成としてもよい。 In the above embodiment, for example, an area sensor is provided on the side of the carry-in / out port (14A) of the cabinet (14), and when a detection signal indicating the presence of a human body is input from the area sensor, the control unit is a large table ( It is possible to apply a configuration in which the drive motor (46) is controlled so as to temporarily stop the rotation of 30). In addition, for example, an indexing device that rotates the first rotary table around the rotation axis of the first rotary table in rotation angle increments set according to the arrangement of the second rotary table is provided for driving the rotary of the first rotary table. It is good also as such a structure.
　さらに、上記実施形態では、図６に示されるように、遠心式投射機２０は大テーブル３０の上方側に一台配置されているが、大テーブル３０（第一回転テーブル）の上方側に配置されて大テーブル３０（第一回転テーブル）上の一部を投射領域（Ｘ）とする遠心式投射機（２０）は、複数台設置されてもよい。 Further, in the above embodiment, as shown in FIG. 6, one centrifugal projector 20 is disposed on the upper side of the large table 30, but is disposed on the upper side of the large table 30 (first rotary table). Then, a plurality of centrifugal projectors (20) having a projection area (X) on a part of the large table 30 (first rotary table) may be installed.
　さらにまた、上記実施形態では、ショット処理装置は、遠心式投射機２０を備えたショットブラスト装置１０とされているが、ショット処理装置は、遠心式投射機２０を備えたショットピーニング装置であってもよい。なお、上記実施形態では大テーブル３０の回転速度は非常に遅いため、当該大テーブル３０の回転中に作業者による被処理対象物１２の載せ降ろし作業を行っているが、前記制御部に接続されたエリアセンサ（図示せず）を前記キャビネット１４の搬入出口１４Ａの縁部に配置することもできる。この場合には、搬入出口１４Ａ近傍の人体を検出して人体の存否を示す検知信号を前記制御部６４に出力することで、前記大テーブル３０の回転を一時停止するように制御するため、より安全に被処理対象物１２を載せ降ろしすることが可能となる。 Furthermore, in the above embodiment, the shot processing apparatus is the shot blasting apparatus 10 including the centrifugal projector 20, but the shot processing apparatus is a shot peening apparatus including the centrifugal projector 20. Also good. In the above-described embodiment, the rotation speed of the large table 30 is very slow. Therefore, the operator loads and unloads the workpiece 12 while the large table 30 is rotating, but is connected to the control unit. An area sensor (not shown) may be arranged at the edge of the carry-in / out port 14A of the cabinet 14. In this case, by detecting the human body in the vicinity of the loading / unloading port 14A and outputting a detection signal indicating the presence or absence of the human body to the control unit 64, the rotation of the large table 30 is controlled to be temporarily stopped. It becomes possible to load and unload the object 12 to be processed safely.
