- the dust removing device 100 of the present embodiment includes the cover plate 102 that covers the sensor detection section 10 and the blow section 104 that blows the fluid F onto the cover plate 102 .
- the blow section 104 has a buffer tank 106 , a Coanda flow path 108 and an outlet 110 .
- the buffer tank 106 temporarily stores the fluid F. Thereby, variations in the pressure of the fluid F can be reduced. Therefore, variations in flow velocity of the fluid F in the longitudinal direction of the outlet 110 can be reduced.
- the Coanda flow path 108 guides the fluid F in the buffer tank 106 to the blowout port 110 .
- the Coanda flow path 108 also has a curved Coanda surface 114 .
- the Coanda flow path 108 guides the fluid F that has flowed into the Coanda flow path 108 from the buffer tank 106 to the outlet 110 while drawing the fluid F toward the Coanda surface 114 due to the Coanda effect. This makes it possible to give directivity to the fluid F that blows out from the blowout port 110 and control the blowing direction.

- the installation surface of the sensor detection unit 10 in the light receiving sensor 8 may not be flat. Therefore, even if the fluid F is blown in the direction along the installation surface, there is a possibility that the unevenness of the installation surface disturbs the airflow and the fluid F does not flow uniformly over the entire sensor detection unit 10 .
- a uniform airflow is likely to occur over the entire area above the sensor detection section 10 .
- the pressure variation of the fluid F is reduced by the buffer tank 106, the directivity of the airflow is given by the Coanda flow path 108, and the fluid F flows along the surface of the flat cover plate 102 covering the sensor detection part 10.
- the airflow can be uniformly applied to the entire area above the sensor detection section 10 .
- the dust D can be removed by narrowing it down to the minimum necessary range. Therefore, the improvement of the removal efficiency of the dust D can be aimed at.
- the amount of scattered dust D can be reduced, and the possibility that the dust D adheres to the conveyed object W can be reduced.
- a cover plate 102 having an area larger than that of the sensor detection unit 10 is preferably used. As a result, the dust D removed from the area above the sensor detection section 10 can be deposited on the outer edge of the cover plate 102 . As a result, the possibility that the dust D scatters and adheres to the conveyed object W can be further reduced.

- the straight portion 116 By providing the straight portion 116 , it is possible to generate an air current floating from the surface of the cover plate 102 in the vicinity of the outlet 110 . Due to this floating air current, the falling speed of the dust D falling onto the sensor detecting section 10 can be suppressed. As a result, the dust D falling onto the sensor detection section 10 can be easily expelled to the area outside the sensor detection section 10 .

- the connecting portion 118 is an opening that is provided in the ceiling surface 106 a and connects the internal space of the buffer tank 106 and the Coanda flow path 108 .
- Center C1 is, for example, the geometric center of the aperture.
- the center C2 is, for example, the volumetric center of the buffer tank 106 , in other words, the geometric center of the shape of the internal space of the buffer tank 106 .
- the blowing direction of the fluid F from the blowing port 110 (the blowing direction in the extending direction of the cover plate 102) is aligned with the sensor detecting portion 10. It can make it easier to target an area.
- the direction in which the center C1 of the connection portion 118 is shifted with respect to the center C2 of the buffer tank 106 (whether to move the center C1 toward or away from the sensor detection portion 10) and the amount thereof can be appropriately set according to the direction in which the fluid F is to be blown out. can.
- FIG. 9 is an exploded perspective view of the blow part 104 included in the dust removing device 100 according to Modification 4.

- the first block 120 and the second block 122 are made of metal, resin, or the like having desired rigidity.
- Each block has a recess 124 corresponding to a portion of the buffer tank 106 and a portion of the Coanda channel 108 and a slit 126 corresponding to a portion of the outlet 110 .
- the first block 120 and the second block 122 are stacked such that each recess 124 and each slit 126 face each other.
- the first block 120 and the second block 122 are laminated in the width direction B.
- a packing 128 is arranged between the first block 120 and the second block 122 . By sandwiching the packing 128 between the two blocks, it is possible to suppress the leakage of the fluid F from the gap between the two blocks.
- first block 120 and the second block 122 are fixed relative to each other around a virtual rotation axis X extending in the stacking direction (the width direction B in this embodiment).
- the first block 120 and the second block 122 can be fixed together by a known method such as adhesion or screwing.

- the direction and amount of rotation of the first block 120 and the second block 122 can be appropriately set according to the direction in which the fluid F is desired to be blown out.
- the blowing direction of the fluid F can be adjusted by varying the blowing angle of the fluid F in the longitudinal direction of the blowing port 110. It is considered that this is because there is a flow velocity difference between the fluid F and the fluid F blown out from the area on the block 122 side. It should be noted that this phenomenon was discovered by the present inventors after intensive studies.

Abstract
Description
図6は、変形例1に係る粉塵除去装置100の断面図である。本変形例の粉塵除去装置100は、コアンダ流路108の形状が実施の形態と異なる。すなわち、本変形例のコアンダ流路108は、吹出口110とコアンダ面114との間に、カバープレート102の表面に平行に延びるストレート部116を有する。本変形例のストレート部116は、吹出口110から連続している。
図7は、変形例2に係る粉塵除去装置100の断面図である。本変形例の粉塵除去装置100は、カバープレート102の形状が実施の形態と異なる。すなわち、本変形例のカバープレート102は、センサ検知部10から離れる方向に湾曲した凸状表面を有する。このように、カバープレート102をR形状にすることで、カバープレート102の表面をコアンダ面として機能させ、流体Fをカバープレート102の表面に引き寄せながら流すことができる。これにより、カバープレート102の表面に堆積する粉塵Dをより除去しやすくすることができる。
図8は、変形例3に係る粉塵除去装置100の断面図である。本変形例の粉塵除去装置100は、バッファタンク106およびコアンダ流路108の接続部118の配置が実施の形態と異なる。すなわち、吹出口110の長手方向、つまり幅方向Bに直交する断面において、バッファタンク106およびコアンダ流路108の接続部118の中心C1は、バッファタンク106の内部空間の中心C2に対して、センサ検知部10およびブロー部104が並ぶ方向、つまり搬送方向Aにずれている。接続部118は、天井面106aに設けられてバッファタンク106の内部空間とコアンダ流路108とをつなぐ開口である。中心C1は、例えば当該開口の幾何中心である。中心C2は、例えばバッファタンク106の容積中心、言い換えればバッファタンク106の内部空間の形状の幾何中心である。
図9は、変形例4に係る粉塵除去装置100が備えるブロー部104の分解斜視図である。本変形例の粉塵除去装置100は、ブロー部104の形状が実施の形態と異なる。すなわち、本変形例のブロー部104は、第1ブロック120および第2ブロック122を有する。第1ブロック120および第2ブロック122は、所望の剛性を有する金属や樹脂等で構成される。各ブロックは、バッファタンク106の一部およびコアンダ流路108の一部に対応する凹部124と、吹出口110の一部に対応するスリット126とを有する。
