Description

本発明は、ベルトコンベアのベルト表面に付着した付着物を除去するベルト表面付着物除去設備に関するものである。   The present invention relates to a belt surface deposit removal equipment for removing deposits attached to a belt surface of a belt conveyor.

通常、粉体や塊状物等を搬送するベルトコンベアにおいては、搬送物自体や搬送物が砕けた物がベルト表面に付着してしまうので、そのような付着物をベルト表面から除去するために、付着物除去装置が設置されている。   Usually, in a belt conveyor that conveys powders or lumps, etc., the conveyed product itself or the material that the conveyed product is crushed adheres to the belt surface, so in order to remove such adhered material from the belt surface, A deposit removal device is installed.

例えば、特許文献１には、ベルト表面にスクレーパーを押し付けて付着物を除去することが記載されている。図３は、その様子を示す側面図である。   For example, Patent Document 1 describes that a scraper is pressed against the belt surface to remove deposits. FIG. 3 is a side view showing the state.

図３に示すように、ベルトコンベア１０において、ベルト１で搬送されてきた搬送物３の大部分は、ベルト１がベルトプーリー２で折り返す際に、ベルト１上から落下して排出されるのであるが、搬送物３の一部（搬送物３自体や搬送物３が砕けた物）が、折り返した後のベルト１の表面に付着して付着物２０となってしまう。   As shown in FIG. 3, in the belt conveyor 10, most of the conveyed product 3 conveyed by the belt 1 falls from the belt 1 and is discharged when the belt 1 is folded back by the belt pulley 2. However, a part of the conveyed product 3 (the conveyed product 3 itself or an object obtained by breaking the conveyed product 3) adheres to the surface of the belt 1 after being turned back and becomes an attached material 20.

そこで、特許文献１では、ベルト１の表面にスクレーパー６をバネ９０によって一定の押し付け力で押し付けて、ベルト１表面の付着物２０を除去するようにしている。   Therefore, in Patent Document 1, the scraper 6 is pressed against the surface of the belt 1 with a constant pressing force by a spring 90 to remove the deposits 20 on the surface of the belt 1.

なお、特許文献１には、一定の押し付け力を得るために、バネ９０以外に、ゴムやエアークッションを用いることが示されている。   Note that Patent Document 1 discloses that rubber or an air cushion is used in addition to the spring 90 in order to obtain a constant pressing force.

特開平８−２６４５９号公報JP-A-8-26459

しかしながら、前記特許文献１のように、ベルト１の表面にスクレーパー６をバネ９０等によって一定の押し付け力で押し付ける方法の場合、付着物２０が無いときには、押し付け力がそのままベルト１に作用して、ベルト１の磨耗・損傷を促進することになるとともに、逆に付着物２０の量が増えたときには、押し付け力が不足して、付着物２０を取り切れず、取り切れなかった付着物２０が堆積して、ベルトコンベア１０のフレームの腐食等を招くという問題がある。   However, in the method of pressing the scraper 6 against the surface of the belt 1 with a constant pressing force by the spring 90 or the like as in the above-mentioned Patent Document 1, when there is no deposit 20, the pressing force acts on the belt 1 as it is, In addition to promoting wear and damage to the belt 1, when the amount of the deposit 20 is increased, the pressing force is insufficient and the deposit 20 cannot be removed, and the deposit 20 that cannot be removed is deposited. Thus, there is a problem that the frame of the belt conveyor 10 is corroded.

本発明は、前記のような事情に鑑みてなされたものであり、ベルトコンベアのベルト表面に付着した付着物を除去するに際して、ベルトコンベアの設備損傷（ベルトの摩耗・損傷）を防止しながら、的確に付着物を除去することができるベルトコンベアのベルト表面付着物除去設備を提供することを目的とするものである。   The present invention has been made in view of the circumstances as described above, and when removing deposits attached to the belt surface of the belt conveyor, while preventing equipment damage of the belt conveyor (belt wear / damage), An object of the present invention is to provide a belt surface deposit removing device for a belt conveyor that can accurately remove deposits.

本発明の実施形態（実施形態１、実施形態２）を図面に基づいて説明する。   Embodiments (Embodiments 1 and 2) of the present invention will be described with reference to the drawings.

［実施形態１］
図１は、本発明の実施形態１におけるベルト表面付着物除去設備１１を示す側面図である。 [Embodiment 1]
FIG. 1 is a side view showing a belt surface deposit removal equipment 11 in Embodiment 1 of the present invention.

図１に示すように、ベルトコンベア１０において、ベルト１で搬送されてきた搬送物３の大部分は、ベルト１がベルトプーリー２で折り返す際に、ベルト１上から落下して排出されるのであるが、搬送物３の一部（搬送物３自体や搬送物３が砕けた物）が、折り返した後のベルト１の表面に付着して付着物２０となってしまう。   As shown in FIG. 1, in the belt conveyor 10, most of the conveyed product 3 conveyed by the belt 1 falls from the belt 1 and is discharged when the belt 1 is folded back by the belt pulley 2. However, a part of the conveyed product 3 (the conveyed product 3 itself or an object obtained by breaking the conveyed product 3) adheres to the surface of the belt 1 after being turned back and becomes an attached material 20.

そこで、この実施形態１におけるベルト表面付着物除去設備１１は、付着物２０を除去する前に、付着物２０の付着状態を検出する付着物検出手段（ベルト表面付着物検出器４、ベルト表面付着物検出装置５）と、付着物検出手段が検出した、付着物２０の付着状態の情報を受けて、付着物２０を除去する付着物除去手段（スクレーパー６、スクレーパー位置制御装置７）とを備えている。   Therefore, the belt surface deposit removal equipment 11 in Embodiment 1 detects the deposit state of the deposit 20 before removing the deposit 20 (belt surface deposit detector 4, with belt surface attached). The attachment detection device 5) and the attachment removal means (scraper 6, scraper position control device 7) for removing the attachment 20 upon receiving information on the attachment state of the attachment 20 detected by the attachment detection means. ing.

ここで、ベルト表面付着物検出器４は、例えば、カメラであり、ベルト表面付着物検出装置５は、例えば、画像処理装置である。そして、付着物２０の付着状態の情報とは、付着物２０の有無、付着物２０の種類、付着領域、付着厚さ等に関する情報である。   Here, the belt surface adhering matter detector 4 is, for example, a camera, and the belt surface adhering matter detecting device 5 is, for example, an image processing device. And the information of the adhesion state of the deposit | attachment 20 is the information regarding the presence or absence of the deposit | attachment 20, the kind of the deposit | attachment 20, an adhesion | attachment area | region, adhesion thickness, etc. FIG.

また、スクレーパー６には、位置制御用の油圧シリンダ６ａが取り付けられている。   Further, a hydraulic cylinder 6 a for position control is attached to the scraper 6.

これによって、この実施形態１においては、まず、ベルト１の表面に付着した付着物２０をベルト表面付着物検出器（カメラ）４で撮影し、その画像をベルト表面付着物検出装置（画像処理装置）５によって解析して、付着物２０の付着状態（付着物２０の有無、付着物２０の種類、付着領域、付着厚さ）を検出し、その付着物２０の付着状態の情報（付着物付着状態情報）をスクレーパー位置制御装置７に送信する。   Accordingly, in the first embodiment, first, the deposit 20 attached to the surface of the belt 1 is photographed by the belt surface deposit detector (camera) 4, and the image is taken as a belt surface deposit detector (image processing apparatus). ) 5 to detect the adhesion state (the presence / absence of the deposit 20, the type of the deposit 20, the adhesion area, the adhesion thickness) of the deposit 20, and information on the adhesion state of the deposit 20 (attachment adhesion Status information) is transmitted to the scraper position control device 7.

そして、スクレーパー位置制御装置７は、画像処理装置５から送信された付着物付着状態情報に基づいて、スクレーパー６のベルト１表面への押し付け力が適切な値となるように、油圧シリンダ６ａを作動させて、スクレーパー６の位置を制御する。   Then, the scraper position control device 7 operates the hydraulic cylinder 6a based on the attached matter adhesion state information transmitted from the image processing device 5 so that the pressing force of the scraper 6 against the surface of the belt 1 becomes an appropriate value. Thus, the position of the scraper 6 is controlled.

例えば、付着物２０が無い場合には、スクレーパー６をベルト１表面に接触しないようにして、押し付け力を０とし、付着物２０の付着厚さが厚くなるにしたがって、スクレーパー６のベルト１表面への押し付け量を大きくして、その付着物２０を除去できる適切な押し付け力になるようにする。逆に、付着物２０の付着厚さが薄くなれば、それに応じて、スクレーパー６のベルト１表面への押し付け量を小さくして、その付着物２０を除去できる適切な押し付け力に下げる。   For example, when there is no deposit 20, the scraper 6 is not brought into contact with the surface of the belt 1, the pressing force is set to 0, and the thickness of the deposit 20 increases toward the surface of the belt 1 of the scraper 6. The pressing amount is increased so that an appropriate pressing force capable of removing the deposit 20 is obtained. On the contrary, if the adhesion thickness of the deposit 20 is reduced, the pressing amount of the scraper 6 against the surface of the belt 1 is reduced accordingly, and the pressing force is reduced to an appropriate pressing force that can remove the deposit 20.

なお、付着物２０の付着状態に対しての、スクレーパー６の適切な押し付け力（すなわち、スクレーパー６の適切な位置）については、事前試験等によって、データベース化しておく。   Note that an appropriate pressing force of the scraper 6 against the attached state of the deposit 20 (that is, an appropriate position of the scraper 6) is made into a database by a preliminary test or the like.

このようにして、この実施形態１においては、ベルトコンベア１０のベルト１表面に付着した付着物２０を除去するに際して、付着物２０の除去を行う前に、カメラ４と画像処理装置５によって、付着物２０の付着状態を検出しておき、その付着物２０の付着状態に基づいて、スクレーパー６が適切な位置（適切な押し付け力）になるように、フィードフォワード制御をしているので、ベルトコンベア１０の設備損傷（ベルトの摩耗・損傷）を防止しながら、的確に付着物を除去することができる。   As described above, in the first embodiment, when the deposit 20 attached to the surface of the belt 1 of the belt conveyor 10 is removed, the attachment by the camera 4 and the image processing device 5 is performed before the deposit 20 is removed. Since the adhesion state of the kimono 20 is detected and the feedforward control is performed so that the scraper 6 is in an appropriate position (appropriate pressing force) based on the adhesion state of the deposit 20, the belt conveyor While preventing 10 equipment damage (belt wear / damage), deposits can be removed accurately.

なお、付着物検出手段として用いるカメラ４は複数台使用してもよい。また、非接触式距離計（赤外線距離計、超音波距離計）と併用してもよい。   A plurality of cameras 4 used as the adhering matter detection means may be used. Moreover, you may use together with a non-contact-type distance meter (an infrared distance meter, an ultrasonic distance meter).

また、ここでは、付着物除去手段として、油圧シリンダで位置を制御する油圧シリンダ式スクレーパーを用いているが、モータで位置を制御するモータ可動式スクレーパーを用いてもよい。   Here, as the deposit removing means, a hydraulic cylinder scraper whose position is controlled by a hydraulic cylinder is used, but a motor movable scraper whose position is controlled by a motor may be used.

また、付着物除去手段として、スクレーパー６に加えて、流体噴射装置（ウオータージェット、エアブロー等）を設置して、付着物２０の付着状態に基づいて、適宜、スクレーパー６または／および流体噴射装置を使用するようにしてもよい。   Further, in addition to the scraper 6, a fluid ejecting device (water jet, air blow, etc.) is installed as the deposit removing means, and the scraper 6 and / or the fluid ejecting device is appropriately selected based on the adhered state of the deposit 20. It may be used.

その際には、前述したデータベースに、流体噴射装置の噴射圧や噴射流量等についても収納しておく。   At that time, the above-mentioned database also stores the injection pressure and the injection flow rate of the fluid injection device.

［実施形態２］
図２は、本発明の実施形態２におけるベルト表面付着物除去設備１２を示す側面図である。 [Embodiment 2]
FIG. 2 is a side view showing the belt surface deposit removing equipment 12 in Embodiment 2 of the present invention.

図２に示すように、この実施形態２におけるベルト表面付着物除去設備１２は、上記の図１に示した実施形態１におけるベルト表面付着物除去設備１１と基本的な構成は同じであるが、それに加えて、スクレーパー６によって付着物２０を除去した後に、付着物２０の残存状態を検出する付着物検出手段（ベルト表面付着物検出器８、ベルト表面付着物検出装置９）を備えている。   As shown in FIG. 2, the belt surface deposit removal equipment 12 in the second embodiment has the same basic configuration as the belt surface deposit removal equipment 11 in the first embodiment shown in FIG. In addition, after the deposit 20 is removed by the scraper 6, deposit detection means (belt surface deposit detector 8, belt surface deposit detection device 9) that detects the remaining state of the deposit 20 is provided.

ここで、ベルト表面付着物検出器８は、例えば、カメラであり、ベルト表面付着物検出装置９は、例えば、画像処理装置である。   Here, the belt surface adhering matter detector 8 is, for example, a camera, and the belt surface adhering matter detecting device 9 is, for example, an image processing device.

これによって、スクレーパー６で付着物２０を除去した後のベルト１表面をベルト表面付着物検出器（カメラ）８で撮影し、その画像をベルト表面付着物検出装置（画像処理装置）９によって解析して、付着物２０の残存状態（付着物２０の有無、付着物２０の種類、付着領域、付着厚さ）を検出し、その付着物２０の残存状態の情報（付着物残存状態情報）をスクレーパー位置制御装置７に送信する。   As a result, the surface of the belt 1 after the deposit 20 is removed by the scraper 6 is photographed by the belt surface deposit detector (camera) 8 and the image is analyzed by the belt surface deposit detector (image processing device) 9. Then, the remaining state of the deposit 20 (presence / absence of the deposit 20, type of deposit 20, adhesion region, deposit thickness) is detected, and information on the remaining state of the deposit 20 (deposit matter remaining state information) is scraper. Transmit to the position control device 7.

そして、スクレーパー位置制御装置７は、画像処理装置９から送信された付着物残存状態情報に基づいて、スクレーパー６のベルト１表面への押し付け力が適切な値となるように、油圧シリンダ６ａを作動させて、スクレーパー６の位置を微調整する。すなわち、フィードバック制御を行う。   Then, the scraper position control device 7 operates the hydraulic cylinder 6a based on the attached matter remaining state information transmitted from the image processing device 9 so that the pressing force of the scraper 6 against the surface of the belt 1 becomes an appropriate value. And finely adjust the position of the scraper 6. That is, feedback control is performed.

例えば、付着物２０が残存するようであれば、それに応じて、スクレーパー６のベルト１表面への押し付け量を大きくして、押し付け力を上げる。   For example, if the deposit 20 remains, the pressing force of the scraper 6 against the surface of the belt 1 is increased to increase the pressing force.

なお、付着物残存状態情報と、それに基づく押し付け量の増加（すなわち、押し付け力の上昇）については、実施形態１において述べた、スクレーパー６の適切な押し付け力（すなわち、スクレーパー６の適切な位置）に関するデータベースに反映させる。   In addition, about the deposit remaining state information and the increase in the pressing amount based on the information (that is, the increase in pressing force), the appropriate pressing force of the scraper 6 (that is, the appropriate position of the scraper 6) described in the first embodiment. To be reflected in the database.

このようにして、この実施形態２においては、ベルトコンベア１０のベルト１表面に付着した付着物２０を除去するに際して、付着物２０の除去を行う前に、カメラ４と画像処理装置５によって、付着物２０の付着状態を検出しておき、その付着物２０の付着状態に基づいて、スクレーパー６が適切な位置（適切な押し付け力）になるように、フィードフォワード制御をするのに加えて、付着物２０の除去を行った後に、カメラ８と画像処理装置９によって、付着物２０の残存状態を検出し、その付着物２０の残存状態に基づいて、スクレーパー６が適切な位置（適切な押し付け力）になるように、フィードバック制御を行っているので、より一層、ベルトコンベア１０の設備損傷（ベルトの摩耗・損傷）を防止しながら、的確に付着物を除去することができる。   As described above, in the second embodiment, when the deposit 20 attached to the surface of the belt 1 of the belt conveyor 10 is removed, the attachment is removed by the camera 4 and the image processing device 5 before the deposit 20 is removed. In addition to performing feedforward control so that the scraper 6 is in an appropriate position (appropriate pressing force) based on the adhesion state of the deposit 20, the adhesion state of the deposit 20 is detected. After the kimono 20 is removed, the remaining state of the deposit 20 is detected by the camera 8 and the image processing device 9, and the scraper 6 is positioned at an appropriate position (appropriate pressing force) based on the remaining state of the deposit 20. ), The feedback control is performed so that the deposits can be removed accurately while further preventing damage to the belt conveyor 10 (belt wear / damage). It can be.

なお、付着物検出手段として用いるカメラ８は複数台使用してもよい。また、非接触式距離計（赤外線距離計、超音波距離計）と併用してもよい。   A plurality of cameras 8 used as the adhering matter detection means may be used. Moreover, you may use together with a non-contact-type distance meter (an infrared distance meter, an ultrasonic distance meter).
