Abstract

A projection material is prevented from coming out of a workpiece transferring outlet, a sealing member for sealing between a door and the workpiece transferring outlet is prevented from wearing off, and the configuration is simplified. In an abrasive blasting device (10), a drum (16) rotates by means of a rotation driving unit (18) with the vertical direction functioning as the rotation axis. When the drum (16) is positioned in the projection position, the opening (16A) of the drum (16) faces a different direction from a workpiece transfer outlet (28). Therefore, even when a projection material is projected into the drum (16) through the opening (16A) while the drum (16) is positioned in the projection position, it is possible to prevent the projection material from being projected to the side of the workpiece transfer outlet (28). As a consequence, even when a door (14) is opened after processing a workpiece, it is possible to prevent the projection material from coming out of the workpiece transfer outlet (28) and to prevent a sealing member for sealing between the door (14) and the workpiece transfer outlet (28) from wearing off. Moreover, the configuration can be simplified because there is no longer the need for a liner for protecting the door (14).

　このショット処理装置によれば、ドラムが投射位置にあるときには、ドラムの開口が水平方向よりも上側を向いた状態で上下方向にドラムが揺動されると共に、このドラムが有底筒状体中心軸周りに回転される。従って、ドラム内のワークを撹拌、転倒させることができるので、ワークを均一に仕上げることができる。 According to this shot processing apparatus, when the drum is at the projection position, the drum is swung in the vertical direction with the drum opening facing upward from the horizontal direction, and the drum is centered on the bottomed cylindrical body. It is rotated around the axis. Accordingly, since the work in the drum can be stirred and overturned, the work can be finished uniformly.
　第4の観点に係る発明のショット処理装置は、第3の観点に係る発明のショット処理装置において、前記揺動駆動部が、前記ドラムが前記ワーク搬入出位置にあるときに、前記ドラムを、前記開口が水平方向よりも下側を向くワーク搬出姿勢とさせることができ、前記ドラムが、前記ワーク搬出姿勢にあるときに、前記ドラムの開口側の端部が前記ワーク搬入出口よりも前記キャビネットの外側に突出される構成とされている。 The shot processing apparatus of the invention according to a fourth aspect is the shot processing apparatus of the invention according to the third aspect, wherein the swing drive unit is configured such that when the drum is in the workpiece loading / unloading position, When the drum is in the workpiece unloading posture, the end of the drum on the opening side is closer to the cabinet than the workpiece loading / unloading port. It is set as the structure protruded outside.
　このショット処理装置によれば、ドラムがワーク搬入出位置にあるときには、ドラムの開口が水平方向よりも下側を向くようにして、ドラムをワーク搬出姿勢とすることができる。これにより、ドラム内のワークをドラムの開口側に移動させることができるので、ワーク搬出時の作業性を良好にすることができる。 According to this shot processing apparatus, when the drum is in the workpiece loading / unloading position, the drum can be set in the workpiece loading posture such that the opening of the drum faces downward from the horizontal direction. Thereby, since the workpiece | work in a drum can be moved to the opening side of a drum, workability | operativity at the time of workpiece | work carrying-out can be made favorable.
　　　　しかも、このドラムは、ワーク搬出姿勢にあるときには、ドラムの開口側の端部がワーク搬入出口よりもキャビネットの外側に突出される。従って、ワーク搬出時の作業性をより良好にすることができると共に、ワーク搬出時にワークがキャビネットの内側に落ちてしまうことも抑制することができる。 Furthermore, when this drum is in the workpiece carry-out posture, the end of the drum on the opening side protrudes outside the cabinet from the workpiece carry-in / out port. Therefore, the workability at the time of unloading the workpiece can be improved, and the workpiece can be prevented from falling inside the cabinet at the time of unloading the workpiece.
　第5および第6の観点に係る発明のショット処理装置は、それぞれ第3又は第4の観点に係る発明のショット処理装置において、前記ドラムの内周面に、前記ドラムの底部側に向かって延びるスパイラル状の突起が形成され、前記回転駆動部が、前記ドラムが前記投射位置にあるときには、ワークがスパイラル状の突起によって前記ドラムの底部側に進むように前記ドラムを回転させ、前記ドラムが前記ワーク搬出姿勢にあるときには、ワークがスパイラル状の突起によって前記ドラムの開口側に進むように前記ドラムを回転させる構成とされている。 The shot processing apparatus of the invention according to the fifth and sixth aspects is the shot processing apparatus of the invention according to the third or fourth aspect, respectively, and extends toward the inner peripheral surface of the drum toward the bottom side of the drum When the spiral projection is formed and the rotation driving unit rotates the drum so that the workpiece advances to the bottom side of the drum by the spiral projection when the drum is at the projection position, the drum is When the workpiece is in the workpiece carry-out posture, the drum is rotated so that the workpiece advances toward the opening side of the drum by a spiral protrusion.
　このショット処理装置によれば、前記突起は、ドラムの底部側に向かってスパイラル状に形成されているが、ドラムが投射位置にあるときには、ワークがスパイラル状の突起によってドラムの底部側に進むようにドラムを回転させるので、ワークをドラムの底部側へ移動させることができる。これにより、ワークを底部で跳ね返すことができ、より一層効果的に、ワークを撹拌、転倒させることができる。 According to this shot processing apparatus, the protrusion is formed in a spiral shape toward the bottom side of the drum. However, when the drum is at the projection position, the workpiece is advanced to the bottom side of the drum by the spiral protrusion. Since the drum is rotated, the workpiece can be moved to the bottom side of the drum. Thereby, the work can be rebounded at the bottom, and the work can be stirred and overturned more effectively.
　一方、ドラムがワーク搬出姿勢にあるときには、ワークがスパイラル状の突起によってドラムの開口側に進むようにドラムを回転させるので、ワークをドラムの開口側へ移動させることができる。これにより、ワーク搬出時の作業性を向上させることができる。

On the other hand, when the drum is in the workpiece carry-out posture, the drum is rotated so that the workpiece advances toward the opening side of the drum by the spiral projection, so that the workpiece can be moved to the opening side of the drum. Thereby, workability | operativity at the time of workpiece | work carrying-out can be improved.

　ドラム１６は、図５～図７に示されるように、開口１６Ａを有する有底筒状に形成されており、キャビネット１２に収容されている。図１１に示されるように、このドラム１６の内周面１６Ｂには、ドラム１６の底部１６Ｃ側に向かって延びるスパイラル状(ねじ山状)の突起４２が形成されている。 As shown in FIGS. 5 to 7, the drum 16 is formed in a bottomed cylindrical shape having an opening 16A and is accommodated in the cabinet 12. As shown in FIG. 11, a spiral (thread-like) protrusion 42 extending toward the bottom 16 </ b> C side of the drum 16 is formed on the inner peripheral surface 16 </ b> B of the drum 16.
　旋回駆動部１８は、図５～図７に示されるように、旋回駆動モータ４４と、旋回駆動リンク４６と、旋回軸４８と、フレーム５０とを有している。旋回駆動モータ４４は、キャビネット１２の上壁部１２Ｅに取り付けられており、旋回駆動リンク４６は、旋回駆動モータ４４の出力軸と旋回軸４８の上端とを連結している。 The turning drive unit 18 includes a turning drive motor 44, a turning drive link 46, a turning shaft 48, and a frame 50, as shown in FIGS. The turning drive motor 44 is attached to the upper wall portion 12E of the cabinet 12, and the turning drive link 46 connects the output shaft of the turning drive motor 44 and the upper end of the turning shaft 48.
　旋回軸４８は、鉛直方向に延びており、キャビネット１２の上壁部１２Ｅに回転可能に支持されている。この旋回軸４８の下端側は、キャビネット１２の上壁部１２Ｅを貫通し、キャビネット１２の内側に位置されている。 The turning shaft 48 extends in the vertical direction and is rotatably supported by the upper wall portion 12E of the cabinet 12. The lower end side of the turning shaft 48 passes through the upper wall portion 12 </ b> E of the cabinet 12 and is positioned inside the cabinet 12.
　フレーム５０は、旋回軸４８の下端に固定され、水平方向に延びた基部５０Ａと、この基部５０Ａの両端から下側に延びる一対の腕部５０Ｂとを有している。一対の腕部５０Ｂには、後述するように、揺動アーム５４及び回転駆動部２２を介してドラム１６が固定されている。 The frame 50 is fixed to the lower end of the turning shaft 48 and has a base portion 50A extending in the horizontal direction and a pair of arm portions 50B extending downward from both ends of the base portion 50A. As will be described later, the drum 16 is fixed to the pair of arm portions 50B via the swing arm 54 and the rotation drive unit 22.
　そして、旋回駆動モータ４４が正逆転されると、旋回駆動リンク４６が作動し、鉛直方向を旋回軸として、ドラム１６がフレーム５０、揺動アーム５４、及び、回転駆動部２２と一体に旋回される。また、ここでは、一例として、ドラム１６は、開口１６Ａがワーク搬入出口２８を向くワーク搬入出位置Ｐ１，Ｐ５と、開口１６Ａがワーク搬入出口２８とは異なる方向（つまり、後述する投射ユニット２４側）を向く投射位置Ｐ２～Ｐ４とに旋回される。投射位置Ｐ２～Ｐ４は、ワーク搬入出位置Ｐ１，Ｐ５に対してドラム１６が９０度旋回された位置に設定されている。 When the turning drive motor 44 is rotated forward and backward, the turning drive link 46 is operated, and the drum 16 is turned together with the frame 50, the swing arm 54, and the rotation drive unit 22 with the vertical direction as the turning axis. The Further, here, as an example, the drum 16 has a workpiece loading / unloading position P1, P5 in which the opening 16A faces the workpiece loading / unloading port 28, and a direction in which the opening 16A is different from the workpiece loading / unloading port 28 (that is, a projection unit 24 side described later ) To the projection positions P2 to P4. The projection positions P2 to P4 are set at positions where the drum 16 is turned 90 degrees with respect to the work loading / unloading positions P1 and P5.
　揺動駆動部２０は、フレーム５０に取り付けられている。この揺動駆動部２０は、揺動駆動シリンダ５２と、揺動アーム５４とを有している。揺動駆動シリンダ５２は、図４に示されるように、フレーム５０に固定されたシリンダ本体部５２Ａと、このシリンダ本体部５２Ａに対して突出及び没入される駆動軸５２Ｂとを有している。 The swing drive unit 20 is attached to the frame 50. The swing drive unit 20 includes a swing drive cylinder 52 and a swing arm 54. As shown in FIG. 4, the oscillating drive cylinder 52 has a cylinder body 52A fixed to the frame 50, and a drive shaft 52B that protrudes and is immersed in the cylinder body 52A.
　揺動アーム５４は、図５に示されるように、一対の腕部５０Ｂの間に配置された基部５４Ａと、この基部５４Ａの両側から下側に延びる一対の連結部５４Ｂとを有している。基部５４Ａには、後述する回転駆動部２２を介してドラム１６が固定されている。一対の連結部５４Ｂは、水平方向に延びる揺動軸５６によって一対の腕部５０Ｂにそれぞれ回転可能に連結されている。また、一対の連結部５４Ｂのうち一方の連結部５４Ｂは、揺動軸５６から下側にずれた位置にて駆動軸５２Ｂの先端と連結されている。 As shown in FIG. 5, the swing arm 54 has a base portion 54A disposed between the pair of arm portions 50B and a pair of connecting portions 54B extending downward from both sides of the base portion 54A. . The drum 16 is fixed to the base 54A via a rotation driving unit 22 described later. The pair of connecting portions 54B are rotatably connected to the pair of arm portions 50B by swinging shafts 56 extending in the horizontal direction. Further, one of the pair of connecting portions 54B is connected to the tip of the drive shaft 52B at a position shifted downward from the swing shaft 56.
　そして、図４に示されるシリンダ本体部５２Ａに対して駆動軸５２Ｂが突出及び没入すると、フレーム５０と一体に回転駆動部２２及びドラム１６が揺動する。ここでは、一例として、ドラム１６の揺動角度は、水平方向に対して－１０度～３５度の範囲に設定されている。 Then, when the drive shaft 52B protrudes and immerses with respect to the cylinder body 52A shown in FIG. 4, the rotary drive unit 22 and the drum 16 swing together with the frame 50. Here, as an example, the swing angle of the drum 16 is set in a range of −10 degrees to 35 degrees with respect to the horizontal direction.
　また、後述するように、ドラム１６は、開口１６Ａがワーク搬入出口２８を向くワーク搬入出位置にあるときに、開口１６Ａが水平方向よりも下側を向くワーク搬出姿勢Ｐ５を取り得るが、このときには、ドラム１６の開口１６Ａ側の端部がワーク搬入出口２８よりもキャビネット１２の外側に突出されるように、ドラム１６とワーク搬入出口２８との相対位置が設定されている。 Further, as will be described later, when the drum 16 is in a workpiece loading / unloading position in which the opening 16A faces the workpiece loading / unloading port 28, the drum 16 can take a workpiece unloading posture P5 in which the opening 16A faces downward from the horizontal direction. In some cases, the relative position between the drum 16 and the workpiece loading / unloading port 28 is set so that the end of the drum 16 on the opening 16A side protrudes outside the cabinet 12 from the workpiece loading / unloading port 28.
　回転駆動部２２は、回転駆動モータ５８と、駆動ホイール６０と、従動ホイール６２と、回転駆動チェーン６４とを有している。回転駆動モータ５８は、揺動アーム５４に取り付けられており、回転駆動ホイール６０は、回転駆動モータ５８の駆動軸に固定されている。従動ホイール６２は、ドラム１６の底部であって、ドラム１６の回転軸と同軸上に取り付けられており、回転駆動チェーン６４は、駆動ホイール６０と従動ホイール６２に掛け回されている。 The rotation drive unit 22 includes a rotation drive motor 58, a drive wheel 60, a driven wheel 62, and a rotation drive chain 64. The rotation drive motor 58 is attached to the swing arm 54, and the rotation drive wheel 60 is fixed to the drive shaft of the rotation drive motor 58. The driven wheel 62 is attached to the bottom of the drum 16 and coaxially with the rotation axis of the drum 16, and the rotary drive chain 64 is wound around the drive wheel 60 and the driven wheel 62.
　そして、回転駆動モータ５８が正逆転すると、この回転力が駆動ホイール６０、回転駆動チェーン６４、及び、従動ホイール６２を介してドラム１６に伝達され、ドラム１６が有底筒状体中心軸周りに正逆転される。 When the rotational drive motor 58 is rotated forward and backward, this rotational force is transmitted to the drum 16 via the drive wheel 60, the rotational drive chain 64, and the driven wheel 62, and the drum 16 is moved around the center axis of the bottomed cylindrical body. It will be reversed.
　投射ユニット２４は、例えば、遠心式投射装置とされており、図１に示されるように、上述のキャビネット１２の側壁部１２Ｂに形成された傾斜部１２Ｄに取り付けられている。この投射ユニット２４は、ドラム１６が投射位置Ｐ２～Ｐ４にあるときには、このドラム１６の開口１６Ａを通じてドラム１６内に投射材を投射する。 The projection unit 24 is, for example, a centrifugal projection device, and is attached to an inclined portion 12D formed on the side wall portion 12B of the cabinet 12 as shown in FIG. The projection unit 24 projects a projection material into the drum 16 through the opening 16A of the drum 16 when the drum 16 is at the projection positions P2 to P4.
　制御盤２６は、上述の開閉駆動モータ４０、旋回駆動モータ４４、揺動駆動シリンダ５２、回転駆動モータ５８等と電気的に接続されている。この制御盤２６には、開閉駆動モータ４０、旋回駆動モータ４４、揺動駆動シリンダ５２、回転駆動モータ５８を駆動させるためのプログラムが記憶されている。そして、制御盤２６は、操作者の操作に応じてプログラムを実行し、後に詳述するように、開閉駆動モータ４０、旋回駆動モータ４４、揺動駆動シリンダ５２、回転駆動モータ５８を駆動させる。 The control panel 26 is electrically connected to the opening / closing drive motor 40, the turning drive motor 44, the swing drive cylinder 52, the rotation drive motor 58, and the like described above. The control panel 26 stores a program for driving the opening / closing drive motor 40, the turning drive motor 44, the swing drive cylinder 52, and the rotation drive motor 58. The control panel 26 executes a program in accordance with the operation of the operator, and drives the opening / closing drive motor 40, the turning drive motor 44, the swing drive cylinder 52, and the rotation drive motor 58, as will be described in detail later.
　次に、上述のショット処理装置１０の動作について説明する。 Next, the operation of the above shot processing apparatus 10 will be described.
　先ず、ワークをドラム１６に搬入するときには、一対の扉１４が開放され、ドラム１６の開口１６Ａがワーク搬入出口２８を向くように、ドラム１６がワーク搬入出位置に位置される。また、このとき、ドラム１６は、開口１６Ａが水平方向よりも上側を向くワーク搬入姿勢Ｐ１とされる。ここでは、一例として、ドラム１６の全体が鉄製とされた場合には、ドラム１６は水平方向に対して開口１６Ａが上側を向くように２５度傾斜される。一方、ドラム１６の内周面１６Ｂにゴム材が貼り付けられた場合には、搬入中、ドラム１６は水平方向に対して開口１６Ａが上側を向くように３０度傾斜される。 First, when a workpiece is carried into the drum 16, the pair of doors 14 are opened, and the drum 16 is positioned at the workpiece loading / unloading position so that the opening 16A of the drum 16 faces the workpiece loading / unloading port 28. At this time, the drum 16 is in a workpiece loading posture P1 in which the opening 16A faces upward from the horizontal direction. Here, as an example, when the entire drum 16 is made of iron, the drum 16 is inclined by 25 degrees so that the opening 16A faces upward with respect to the horizontal direction. On the other hand, when a rubber material is affixed to the inner peripheral surface 16B of the drum 16, the drum 16 is inclined 30 degrees so that the opening 16A faces upward with respect to the horizontal direction during loading.
　なお、ワークが自動搬入装置により自動的にドラム１６内に搬入される場合には、回転駆動モータ５８が駆動されてドラム１６が回転されるようにしても良い。そして、これにより、ドラム１６内のワークがドラム１６の底部１６Ｃ側へ移動するようにしても良い。一方、ワークが作業者により手作業でドラム１６内に搬入される場合には、ドラム１６が停止させた状態に維持されるのが望ましい。 When the workpiece is automatically loaded into the drum 16 by the automatic loading device, the drum 16 may be rotated by driving the rotation drive motor 58. Thereby, the work in the drum 16 may be moved to the bottom 16C side of the drum 16. On the other hand, when the work is manually carried into the drum 16 by the operator, it is desirable to keep the drum 16 stopped.
　そして、ドラム１６にワークが搬入されると、旋回駆動モータ４４が正転され、ドラム１６がワーク搬入出位置Ｐ１に対して９０度旋回されて、開口１６Ａが投射ユニット２４側を向く投射位置Ｐ２に位置される。また、開閉駆動モータ４０が正転されて、一対の扉１４が閉鎖される。 When the work is carried into the drum 16, the turning drive motor 44 is rotated forward, the drum 16 is turned 90 degrees with respect to the work carry-in / out position P1, and the projection position P2 in which the opening 16A faces the projection unit 24 side. Located in. In addition, the opening / closing drive motor 40 is rotated forward to close the pair of doors 14.
　続いて、ドラム１６が投射位置Ｐ２に位置されると、揺動駆動シリンダ５２が作動されて、シリンダ本体部５２Ａに対して駆動軸５２Ｂが繰り返し突出及び没入される。このとき、ドラム１６は、開口１６Ａが水平方向よりも上側を向いた状態で上下するように揺動される。つまり、ドラム１６の姿勢がＰ２～Ｐ４に変化される。ここでは、一例として、ドラム１６は、水平方向に対して２５～３５度の範囲で揺動される。そして、このようにしてドラム１６が揺動されることにより、ドラム１６内のワークが撹拌、転倒される。 Subsequently, when the drum 16 is positioned at the projection position P2, the swing drive cylinder 52 is operated, and the drive shaft 52B is repeatedly protruded and immersed in the cylinder body 52A. At this time, the drum 16 is swung so as to move up and down with the opening 16A facing upward from the horizontal direction. That is, the posture of the drum 16 is changed from P2 to P4. Here, as an example, the drum 16 is swung in a range of 25 to 35 degrees with respect to the horizontal direction. Then, the workpiece in the drum 16 is stirred and overturned by swinging the drum 16 in this way.
　また、上述のようにしてドラム１６が投射位置で揺動されるときには、回転駆動モータ５８が正転され、ドラム１６が有底筒状体中心軸周りに回転される。そして、このようにしてドラム１６が回転されることにより、ドラム１６内のワークが、スパイラル状の突起４２によってドラム１６の底部１６Ｃ側へ移動される。また、ドラム１６の底部１６Ｃ側へ移動されたワークは、ドラム１６の底部１６Ｃにて跳ね返されて、撹拌、転倒される。 Further, when the drum 16 is swung at the projection position as described above, the rotation drive motor 58 is rotated forward, and the drum 16 is rotated around the center axis of the bottomed cylindrical body. Then, by rotating the drum 16 in this way, the work in the drum 16 is moved to the bottom 16C side of the drum 16 by the spiral protrusion 42. Further, the workpiece moved to the bottom 16C side of the drum 16 is bounced back at the bottom 16C of the drum 16, and is stirred and overturned.
　また、上述のようにしてドラム１６が揺動及び回転されると同時に、投射ユニット２４が作動され、ドラム１６の開口１６Ａを通じてドラム１６内に投射材が投射される。そして、これにより、ドラム１６内のワークに投射材が投射され、ワークが研掃処理される。 Further, at the same time as the drum 16 is swung and rotated as described above, the projection unit 24 is operated, and the projection material is projected into the drum 16 through the opening 16A of the drum 16. As a result, the projection material is projected onto the workpiece in the drum 16 and the workpiece is subjected to a polishing process.
　続いて、ワークの研掃処理が終了すると、揺動駆動シリンダ５２及び回転駆動モータ５８が停止される。このとき、ドラム１６は、開口１６Ａが水平方向よりも上側を向く上向き姿勢Ｐ２とされる。また、開閉駆動モータ４０が逆転されて、一対の扉１４が開放される。 Subsequently, when the workpiece polishing process is completed, the swing drive cylinder 52 and the rotation drive motor 58 are stopped. At this time, the drum 16 is in an upward posture P2 in which the opening 16A faces upward from the horizontal direction. Further, the opening / closing drive motor 40 is reversed to open the pair of doors 14.
　そして、旋回駆動モータ４４が逆転され、ドラム１６が投射位置Ｐ２に対して９０度旋回されて、ワーク搬入出口２８側を向くワーク搬入出位置Ｐ１に位置される。 Then, the turning drive motor 44 is reversed, the drum 16 is turned 90 degrees with respect to the projection position P2, and is positioned at the workpiece loading / unloading position P1 facing the workpiece loading / unloading port 28 side.
　続いて、上述のようにしてドラム１６がワーク搬入出位置Ｐ１に位置されると、揺動駆動シリンダ５２が作動する。そして、これにより、ドラム１６は、開口１６Ａが水平方向よりも下側を向くワーク搬出姿勢Ｐ５とされる。ここでは、一例として、ドラム１６は、水平方向に対して開口１６Ａが下側を向くように－１０度傾斜される。また、このとき、ドラム１６の開口１６Ａ側の端部は、ワーク搬入出口２８よりもキャビネット１２の外側に突出される。 Subsequently, when the drum 16 is positioned at the workpiece loading / unloading position P1 as described above, the swing drive cylinder 52 is operated. As a result, the drum 16 is brought into a workpiece carry-out posture P5 in which the opening 16A faces downward from the horizontal direction. Here, as an example, the drum 16 is tilted by −10 degrees so that the opening 16A faces downward with respect to the horizontal direction. At this time, the end of the drum 16 on the opening 16 </ b> A side protrudes outside the cabinet 12 from the work loading / unloading port 28.
　また、ドラム１６がワーク搬出姿勢Ｐ５とされると、回転駆動モータ５８が逆転され、ドラム１６が逆回転される。そして、これにより、ドラム１６内のワークが、スパイラル状の突起４２によってドラム１６の開口１６Ａ側へ移動される。 Further, when the drum 16 is brought into the workpiece carry-out posture P5, the rotation drive motor 58 is reversed and the drum 16 is rotated in the reverse direction. As a result, the work in the drum 16 is moved toward the opening 16A of the drum 16 by the spiral protrusion 42.
　そして、ドラム１６内のワークが搬出されることで、一連の作業が終了する。 Then, when the work in the drum 16 is carried out, a series of work is completed.
　なお、投射材は、以下のようにして循環される。すなわち、投射材は、ドラム１６に開けられた抜き穴より落ちて、キャビネット１２の下部に設けられたホッパーにより下部スクリューコンベヤ７０へ流れる。そして、下部スクリューコンベヤ７０から運ばれた投射材は、垂直スクリューコンベヤ７２へ送られ上昇してセパレータ７４へ搬送される。 Note that the projection material is circulated as follows. That is, the projection material falls from the punched hole formed in the drum 16 and flows to the lower screw conveyor 70 by the hopper provided in the lower part of the cabinet 12. Then, the projection material conveyed from the lower screw conveyor 70 is sent to the vertical screw conveyor 72 and is lifted and conveyed to the separator 74.
　また、セパレータ７４で選別された使用可能な投射材のみが導入管７６を経て再び投射ユニット２４へ流れる。一方、セパレータ７４で吸引されたエアーと粉じんは、サイクロン７８にて分級される。サイクロン７８にて選別された使用可能な投射材は、キャビネット１２内へ戻される。また、サイクロン７８から流れたエアーと粉じんは、集じん機で分離され、エアーのみ外気へ排気し、粉じんは、回収され廃棄される。 Further, only the usable projection material selected by the separator 74 flows again to the projection unit 24 through the introduction pipe 76. On the other hand, air and dust sucked by the separator 74 are classified by the cyclone 78. Usable projectiles selected by the cyclone 78 are returned to the cabinet 12. The air and dust flowing from the cyclone 78 are separated by a dust collector, and only the air is exhausted to the outside air. The dust is collected and discarded.
　次に、本発明の一実施形態の作用及び効果について説明する。 Next, the operation and effect of one embodiment of the present invention will be described.
　以上詳述したように、本発明の一実施形態に係るショット処理装置１０によれば、ドラム１６は、旋回駆動部１８によって鉛直方向を旋回軸として旋回されるようになっており、ドラム１６が投射位置にあるときには、ドラム１６の開口１６Ａがワーク搬入出口２８とは異なる方向である投射ユニット２４側に向けられる。従って、ドラム１６が投射位置にある状態で、ドラム１６の開口１６Ａを通じてドラム１６内に投射材が投射されても、この投射材がワーク搬入出口２８側へ投射されることを抑制することができる。 As described above in detail, according to the shot processing apparatus 10 according to an embodiment of the present invention, the drum 16 is swung by the swivel drive unit 18 with the vertical direction as the swivel axis. When in the projection position, the opening 16 </ b> A of the drum 16 is directed toward the projection unit 24, which is in a direction different from the work loading / unloading port 28. Therefore, even when the projection material is projected into the drum 16 through the opening 16A of the drum 16 in a state where the drum 16 is at the projection position, the projection material can be prevented from being projected to the workpiece loading / unloading port 28 side. .
　これにより、ワークの処理が完了した後に一対の扉１４を開放しても、投射材がワーク搬入出口２８から出てきてしまったり、一対の扉１４とワーク搬入出口２８との間をシールするシール材が摩耗したりすることを抑制することができる。また、一対の扉１４を保護するためのライナーが不要となり、構造を簡素化することができる。 Thus, even when the pair of doors 14 is opened after the workpiece processing is completed, the projection material comes out from the workpiece loading / unloading port 28 or seals between the pair of doors 14 and the workpiece loading / unloading port 28. It is possible to suppress wear of the material. Further, a liner for protecting the pair of doors 14 is not necessary, and the structure can be simplified.
　しかも、上述の投射位置は、ワーク搬入出位置に対してドラム１６が９０度旋回された位置に設定されているので、投射材がワーク搬入出口２８側へ投射されることをより一層抑制することができる。 Moreover, since the above-described projection position is set to a position where the drum 16 is turned 90 degrees with respect to the workpiece loading / unloading position, the projection material is further suppressed from being projected to the workpiece loading / unloading port 28 side. Can do.
　また、ドラム１６が投射位置にあるときには、ドラム１６の開口１６Ａが水平方向よりも上側を向いた状態で上下に揺動されると共に、このドラム１６が有底筒状体中心軸周りに正回転される。従って、ドラム１６内のワークを撹拌、転倒させることができるので、ワークを均一に仕上げることができる。 When the drum 16 is in the projection position, the drum 16 is swung up and down with the opening 16A of the drum 16 facing upward from the horizontal direction, and the drum 16 is rotated forward about the center axis of the bottomed cylindrical body. Is done. Accordingly, the work in the drum 16 can be stirred and overturned, so that the work can be finished uniformly.
　特に、ドラム１６が投射位置にあるときには、ドラム１６は、有底筒状体中心軸周りに正回転されるので、ドラム１６の内周面１６Ｂに形成されたスパイラル状の突起４２でワークをドラム１６の底部１６Ｃ側へ移動させることができる。これにより、ワークを底部１６Ｃで跳ね返すことができ、より一層効果的に、ワークを撹拌、転倒させることができる。 In particular, when the drum 16 is in the projection position, the drum 16 is normally rotated around the center axis of the bottomed cylindrical body, so that the workpiece is drummed by the spiral protrusion 42 formed on the inner peripheral surface 16B of the drum 16. 16 can be moved to the bottom 16C side. Thereby, the work can be rebounded at the bottom portion 16C, and the work can be stirred and overturned more effectively.
　一方、ドラム１６がワーク搬入出位置にあるときには、ドラム１６の開口１６Ａが水平方向よりも下側を向くようにドラム１６をワーク搬出姿勢とすることができる。これにより、ドラム１６内のワークを開口１６Ａ側に移動させることができるので、ワーク搬出時の作業性を良好にすることができる。 On the other hand, when the drum 16 is in the workpiece loading / unloading position, the drum 16 can be in the workpiece loading posture so that the opening 16A of the drum 16 faces downward from the horizontal direction. Thereby, since the workpiece | work in the drum 16 can be moved to the opening 16A side, workability | operativity at the time of workpiece | work carrying-out can be made favorable.
　しかも、ドラム１６がワーク搬出姿勢にあるときには、ドラム１６が、有底筒状体中心軸周りに逆回転されるので、ドラム１６の内周面１６Ｂに形成されたスパイラル状の突起４２でワークをドラム１６の開口１６Ａ側へ移動させることができる。これにより、ワーク搬出時の作業性を向上させることができる。 In addition, when the drum 16 is in the workpiece carry-out posture, the drum 16 is rotated in the reverse direction around the center axis of the bottomed cylindrical body, so that the workpiece is moved by the spiral protrusion 42 formed on the inner peripheral surface 16B of the drum 16. The drum 16 can be moved toward the opening 16A. Thereby, workability | operativity at the time of workpiece | work carrying-out can be improved.
　また、ドラム１６は、ワーク搬出姿勢にあるときには、開口１６Ａ側の端部がワーク搬入出口２８よりもキャビネット１２の外側に突出される。従って、ワーク搬出時の作業性をより良好にすることができると共に、ワーク搬出時にワークがキャビネット１２の内側に落ちてしまうことも抑制することができる。 Also, when the drum 16 is in the workpiece carry-out posture, the end on the opening 16A side protrudes outside the cabinet 12 from the workpiece loading / unloading port 28. Therefore, the workability at the time of unloading the workpiece can be improved, and the workpiece can be prevented from falling inside the cabinet 12 at the time of unloading the workpiece.
