（２）空気給排手段２０によって、空気口１８を通して、加圧空気供給源２０ａによる空気の供給、集塵機２０ｂによるシュート８内の空気の吸引を繰返し、フレコンバッグ２を膨張・収縮させ、フレコンバッグ２内の残粉を落とし、洗浄する。 (2) The air supply / discharge means 20 repeats the supply of air by the pressurized air supply source 20a through the air port 18 and the suction of the air in the chute 8 by the dust collector 20b to expand and contract the flexible container bag 2, and the flexible container bag Remove remaining powder in 2 and wash.
上述したとおりのフレコンバッグの排出・洗浄装置４の作用効果について説明する。 The operational effects of the flexible container bag discharging / cleaning apparatus 4 as described above will be described.
フレコンバッグの排出・洗浄装置４は、フレコンバッグ２の底部の周縁を、個々に昇降作動を可能に分割支持する複数個の受台６と、フレコンバッグ２の排出口２ｃを下方のシュート８に分離可能に密封状態で連結する連結手段１０と、粉体排出先１２への粉体の排出を開閉する開閉弁１４と、シュート８に設けられ、通気可能な多孔板１６によって閉じられた空気口１８と、この空気口１８を通して断続を可能に、シュート８内に加圧空気を供給あるいはシュート内空気を吸引する空気給排手段２０と、を備え、粉体排出の際は、フレコンバッグ２を支持する複数個の受台６を同時にあるいは交互に昇降させフレコンバッグ２を変形させて排出を促進し、袋内の洗浄の際は、開閉弁１４を閉じ、空気口１８を通して空気給排手段２０により空気を給排し繰返しフレコンバッグ２を膨張・収縮させて残粉を落とし洗浄する。 The flexible container discharge / cleaning device 4 includes a plurality of cradles 6 that individually support the peripheral edge of the bottom of the flexible container bag 2 so as to be movable up and down, and a discharge port 2c of the flexible container bag 2 as a chute 8 below. The connecting means 10 that is connected in a separable and sealing state, the open / close valve 14 that opens and closes the discharge of the powder to the powder discharge destination 12, and the air port provided in the chute 8 and closed by a perforated plate 16 18 and air supply / discharge means 20 for supplying pressurized air into the chute 8 or sucking air in the chute so that the air can be intermittently passed through the air port 18. A plurality of supporting bases 6 are moved up and down simultaneously or alternately to deform the flexible container bag 2 to facilitate discharge. When cleaning the inside of the bag, the opening / closing valve 14 is closed and the air supply / discharge means 20 is passed through the air port 18. By Worry about the paper sheet discharge repeatedly flexible container bag 2 is expanded and contracted the by washing off the residual powder.
したがって、フレコンバッグから粉体を排出する際の、作業員によるフレコンバッグの上げ下げ、打撃を不要にし、また粉体排出途中のフレコンバッグの変形による排出が円滑でない不具合を除き、またフレコンバッグの洗浄を排出作業とともに能率よく行えるようにし、さらに粉体の排出・洗浄の際の粉塵の飛散を防止できるようにし、フレコンバッグの排出・洗浄を能率よく行なえるようにした、フレコンバッグの排出・洗浄装置を提供することができる。 Therefore, when discharging powder from the flexible container bag, the operator does not need to raise, lower, and blow the flexible container bag, and the flexible container bag is not discharged smoothly due to deformation of the flexible container bag. Discharging and cleaning the flexible container bag so that the dust container can be efficiently discharged together with the discharging operation, and dust scattering during the discharging and cleaning of the powder can be prevented. An apparatus can be provided.
このフレコンバッグの排出・洗浄装置４は、排出・洗浄作業中に、粉体の入った、あるいは粉体を排出したフレコンバッグ２を、複数個の受台６によって、しっかりと安定した状態に保持することができる。 The flexible container bag discharging / cleaning device 4 holds the flexible container bag 2 containing powder or discharging powder firmly and stably by a plurality of receiving bases 6 during the discharging / cleaning operation. can do.
またフレコンバッグの排出・洗浄装置４は、底部の周縁を外側から斜め上内方に伸縮作動を可能に押し上げる、受台それぞれに隣接し設置された複数個のプッシャーを備え、フレコンバッグの粉体排出の際、複数個のプッシャーを単独で、あるいは交互に、あるいは同時に伸縮させてフレコンバッグを部分的に上げ下げ変形させ排出を促進させる。 The flexible container discharge / cleaning device 4 includes a plurality of pushers installed adjacent to each of the cradles to push up the peripheral edge of the bottom portion so as to be able to expand and contract diagonally upward and inward from the outside. When discharging, a plurality of pushers are expanded or contracted individually, alternately or simultaneously to partially raise and lower the flexible container bag to promote discharge.
したがって、必要に応じて、「降位置」の受台６に隣接したプッシャー２６を、単独で、あるいは交互に、あるいは同時に伸縮させて、フレコンバッグ２を部分的に上げ下げ変形させ、排出を促進させることができる。特に排出の悪い粉体を確実に排出することができる。 Therefore, if necessary, the pusher 26 adjacent to the cradle 6 in the “down position” is expanded or contracted individually, alternately, or simultaneously to partially raise and lower the flexible container bag 2 to promote discharge. be able to. In particular, it is possible to reliably discharge powder that is poorly discharged.
また、粉体排出の際、所定の残量値まで排出したら、開閉弁であるバタフライ弁１４を閉じ、空気口１８を通して空気給排手段２０により空気を給排し繰返しフレコンバッグ２を膨張・収縮させて粉体を落下させ排出を促進させることができる。 When the powder is discharged to a predetermined remaining amount, the butterfly valve 14 which is an on-off valve is closed, air is supplied / discharged by the air supply / discharge means 20 through the air port 18, and the flexible container bag 2 is repeatedly expanded / contracted. The powder can be dropped to facilitate discharge.
そして、空気給排手段２０は、加圧空気を断続可能に供給する加圧空気供給源２０ａと、空気を断続可能に吸引し排出する吸引源としての集塵機２０ｂと、を備えている。したがって、加圧空気供給源２０ａによって加圧空気を供給するとともに、集塵機２０ｂによって粉塵を発生させることなくフレコンバッグ２内の空気を吸引排出することができる。 The air supply / discharge means 20 includes a pressurized air supply source 20a that supplies pressurized air in an intermittent manner and a dust collector 20b as a suction source that sucks and discharges air in an intermittent manner. Therefore, while supplying pressurized air by the pressurized air supply source 20a, the air in the flexible container bag 2 can be sucked and discharged without generating dust by the dust collector 20b.
また、空気口１８を閉じる多孔板１６が、開閉を可能に設置され、フレコンバッグ２内に空気を給排し繰返しフレコンバッグ２を膨張・収縮させる洗浄の際には「開」状態に位置づける。したがって、洗浄の際には「開状態」の空気口１８を通して十分な空気が給排され、洗浄を効果的に促進することができる。 Further, the perforated plate 16 that closes the air port 18 is installed so as to be openable and closable, and is positioned in the “open” state at the time of cleaning for supplying and discharging air into the flexible container bag 2 and repeatedly expanding and contracting the flexible container bag 2. Therefore, at the time of cleaning, sufficient air is supplied and exhausted through the air port 18 in the “open state”, and cleaning can be effectively promoted.
なお、前記の空気給排手段による排出促進の際には、空気口１８は多孔板１６によって閉じられているので、空気口１８を通して粉体が漏れるのが防止される。 Note that when the air supply / discharge means promotes the discharge, the air port 18 is closed by the perforated plate 16, so that the powder is prevented from leaking through the air port 18.
