Japanese Patent Laid-Open No. 2001-10716 JP 2002-46851 A

  However, the belt cleaner devices described in Patent Documents 1 and 2 have a complicated structure, which causes a problem that the assembling work becomes very complicated. In addition, the replacement cycle of the scraper and scraper blade that wears with use is short, which is disadvantageous in terms of running cost.

  Furthermore, since both of the belt cleaner devices described in Patent Documents 1 and 2 are weak in strength, a scraper or a scraper blade is positive for an adhering substance firmly attached to the outer surface of the conveyor belt. Designed to get around and avoid. For this reason, it has been difficult to remove the adhering matter firmly adhered to the surface of the conveyor belt.

  The present invention has been developed to solve the above technical problems, is easy to assemble, is advantageous in terms of running cost, and is free from deposits adhering to the outer surface of the conveyor belt. An object of the present invention is to provide a novel conveyor belt cleaner with high scraping efficiency.

  The conveyor belt cleaner of the present invention is a conveyor belt cleaner that scrapes and removes the adhering matter adhering to the outer surface of the conveyor belt at the end of the scraping member brought into contact with the outer surface of the conveyor belt, The conveyor belt cleaner includes a gantry having a groove portion for holding a scraping member, and a scraping block which is inserted along the groove portion and arranged adjacently to constitute the scraping member. A plurality of scraping blocks constituting the scraping member are supported for each scraping block, and the supporting position is advanced and retracted along the groove depth direction so that the scraping block is removed from the groove bottom surface. A positioning member that is remote from or close to the positioning member, and by changing the support position of the positioning member, from the groove opening end of the scraping member Protrusion distance, characterized in that is adapted to be adjustable for each individual scraping blocks constituting the scraping members.

  Hereinafter, the conveyor belt cleaner of the present invention will be described in detail.

  The conveyor belt cleaner of the present invention scrapes and removes the adhering matter adhering to the outer surface of the conveyor belt at the end of the scraping member brought into contact with the outer surface of the conveyor belt.

  The conveyor belt cleaner according to the present invention includes a "stand" having a groove portion in which the scraping member is held, and a plurality of the support frames that are inserted along the groove portion and arranged adjacent to each other, thereby disposing the scraping member. By supporting the “scraping block” to be configured and the plurality of scraping blocks to constitute the scraping member for each scraping block, and by moving the support position forward and backward along the groove depth direction. And a "positioning member" for bringing the scraping block away from or close to the bottom surface of the groove.

  The “frame” is provided with a groove portion for holding the scraping member, and is used such that, in use, the groove length direction of the groove portion crosses the traveling direction of the conveyor belt. The end portion of the scraping member held in the groove is brought into contact with the outer surface of the conveyor belt.

  That is, in the present invention, the length in the width direction of the scraping member is determined by the groove length of the groove portion provided on the gantry. Therefore, if the groove length of the groove portion is shorter than the length of the conveyance belt in the width direction, a portion where the end portion of the scraping member does not come into contact with the outer surface of the conveyance belt is generated.

  In general belt conveyors, a lot of deposits are generated at the center in the width direction of the conveyor belt, and not much deposits are generated at both ends in the width direction of the conveyor belt. What is necessary is just to set to the length corresponded to the range which the deposit | attachment generate | occur | produces on the outer surface of a conveyance belt at least as (the groove length of the groove part holding a scraping member).

  However, if there is a portion where the end of the scraping member is not in contact with the outer surface of the conveying belt, the scraped and removed deposit once detours along the scraping member, and the scraping member May be guided to a portion that is not abutted and reattached to the portion.

  Therefore, in the present invention, the groove length of the groove portion provided on the gantry is set to be equal to or longer than the length in the width direction of the conveyor belt, and the groove portion is located at a position crossing the traveling direction of the conveyor belt. Thus, when the gantry is erected, it is preferable that the end portion of the scraping member held in the groove portion can be brought into contact with the entire length of the conveyance belt in the width direction.

  In addition, the said groove part is not restricted to the case where it is provided in linear form in a mount frame, may be curved or bent, and may be provided so that it may become two or more rows.

  A plurality of the “scraping blocks” are inserted along a groove provided in the gantry and are arranged adjacent to each other to constitute the scraping member.

  The scraping block is a block body having a certain thickness that can be inserted into the groove, a certain width that can be inserted along the groove, and a certain height.

  Here, in the conveyance belt cleaner of the present invention, during use, the load is most applied in the thickness direction of the scraping block. If the thickness of the scraping block is made sufficiently thick, the necessary rigidity (physical strength) can be ensured, but since the raw material cost increases, it is not always preferable to increase the thickness extremely.

  That is, the thickness of the scraping block is a matter that should be appropriately determined according to the load applied during use, the material forming the scraping block, etc., and is not limited in general. Generally, it is about 50 mm.

  In particular, in the present invention, the thickness of the scraping block is set to a thickness that can be substantially fitted to the groove width of the groove portion (thickness that is the same as or slightly smaller (about 0.1 to 3 mm) than the groove width of the groove portion). When the scraping block is inserted into the groove portion, it is preferable that the front and rear surfaces of the scraping block can substantially come into surface contact with the front and rear inner wall surfaces of the groove portion.

  In this way, if the thickness of the scraping block is set to be a thickness that can be fitted to the groove width of the groove portion, each scraping block fitted to the groove portion provided in the gantry in the thickness direction. The rigidity with respect to the applied load becomes very high, and even if it comes into contact with the adhered matter firmly adhered to the outer surface of the conveyor belt, it can be easily scraped and removed without breaking.

  Regarding the width of the scraping block, if the width is too long, the number of scraping blocks that can be disposed adjacent to each other along the groove portion is relatively small, and the followability to the outer surface of the conveying belt is deteriorated. .

  On the other hand, when the width of the scraping block is shortened, the number of scraping blocks arranged in the groove portion is relatively increased and the followability to the outer surface of the conveying belt is improved. However, since the number of positioning members to be described later also becomes relatively large and the positioning operation becomes complicated, it is not always preferable to extremely reduce the width of the scraping block.

  That is, the width of the scraping block is a matter that should be appropriately determined according to the length in the width direction of the conveyor belt, the groove length of the groove portion, and the like, and is not limited to about 30 to 300 mm. It is common to do. Further, it is preferable that 3 to 50 pieces, preferably about 5 to 30 pieces can be arranged along the groove.

  The height of the scraping block may be determined as appropriate according to the groove depth of the groove, a support position that can be determined by a positioning member described later, and is not particularly limited.

  However, if the height of the scraping block becomes extremely long, it will be easy to break during use unless the groove depth is set deeply accordingly, whereas if the height of the scraping block becomes extremely short, Since the exchange cycle is shortened, neither is preferable.

  That is, the height of the scraping block is a matter that should be appropriately determined according to the groove depth of the groove, the load applied during use, the material forming the scraping block, etc. Although it is not a thing, it is common to set it as about 30-300 mm. Further, it is preferable that the height is 0.3 to 2 times, preferably about 0.5 to 1.5 times the groove depth of the groove.

  The material for forming the scraping block is not particularly limited as long as the necessary rigidity can be obtained when the scraping block is formed. For example, wood, plastic, rubber or metal is used as the material. Can also be used.

  In particular, in the conveyor belt cleaner of the present invention, it is preferable to form the scraping block with a sintered body mainly composed of a metal oxide called ceramics. A sintered body containing a metal oxide as a main component has high rigidity, excellent wear resistance, and is generally compatible with a conveyor belt generally made of rubber or cloth, and its surface is difficult to be damaged. It is preferable from having.

  As described above, the scraping block used in the present invention is a block body having a certain thickness that can be inserted into the groove, a certain width that can be inserted along the groove, and a certain height. The other shapes are not particularly limited as long as they constitute a scraping member by being arranged adjacent to each other along the groove. In the present invention, it is not necessary to unify the shapes of the individual scraping blocks.

  However, for each scraping block, if the side surfaces of adjacent scraping blocks have a side surface shape that can come into surface contact with each other, the adjacent scraping blocks support each other, so that the scraping member as a whole Increased rigidity. Moreover, it becomes difficult to produce a gap between adjacent scraping blocks, and the scraping efficiency is improved.

  Therefore, in the present invention, as the scraping block, it is preferable to use a scraping block having a side surface shape in which the side surfaces of adjacent scraping blocks can come into surface contact with each other when arranged adjacent to the groove.

  As a suitable example of such a scraping block, there can be mentioned a quadrangular prism-shaped scraping block whose bottom surface shape is a square shape such as a square, a rectangle, a trapezoid, or a parallelogram. The quadrangular prism shape includes those obtained by cutting or rounding the corners and sides.

  The “positioning member” supports the plurality of scraping blocks constituting the scraping member for each of the scraping blocks, and advances and retracts the supporting position along the groove depth direction. The scraping block is moved away from or in the vicinity of the bottom of the groove.

  Since the positioning member supports a plurality of scraping blocks constituting the scraping member for each scraping block, the number thereof is determined according to the number of scraping blocks.

  The positioning member is not particularly limited as long as the scraping block can be supported and the supporting position can be advanced and retracted along the groove depth direction. For example, the positioning member may be configured by arranging a spacer on the inner bottom portion of the groove and overlapping the spacer or changing to a spacer having a different thickness, and can move forward and backward to the bottom surface of the scraping block. The positioning member may be configured by attaching a supporting rod.

  In particular, in the present invention, it is preferable to use a bolt member disposed through the bottom of the groove portion of the gantry as the positioning member.

  That is, this positioning member moves the scraping block remotely or close to the bottom of the groove by moving the shaft of the bolt member arranged through the bottom of the groove in the gantry along the groove depth direction. Since the supporting position can be determined without removing the scraping block from the groove, the positioning operation is very simple.

  And in this invention, the protrusion distance from the groove part opening end of the said scraping member can be adjusted for every scraping block which comprises a scraping member by changing the support position of the said positioning member. Made. As a result, even when the conveyor belt is curved or uneven, the shape of the end of the scraping member is changed according to the curvature or unevenness to scrape the outer surface of the conveyor belt. The end of the take-up member can be followed.

  In addition, when the protruding distance from the groove opening end in each scraping block constituting the scraping member becomes long and the portion buried in the groove in each scraping block becomes short, the groove opening end in the scraping block becomes The stress applied to the contacting portion increases, and the scraping block is easily broken.

  Therefore, in the present invention, at least 50% or more of the height direction of each scraping block is buried in the groove portion with respect to the supporting position of the scraping block by the positioning member, and the remaining portion protruded from the opening end of the groove portion. It is preferable that a scraping member is configured. In this way, the rigidity of each scraping block is increased, and even if it comes into contact with the adhered matter firmly adhered to the conveyor belt, it can be scraped and removed without being easily damaged.

  If the scraping block is completely buried in the groove, the end of the scraping member cannot be brought into contact with the outer surface of the conveying belt. Therefore, the degree of burying in the groove in the scraping block is 95% at the maximum. The following is preferable. Further, wear occurs in each scraping block constituting the scraping member in accordance with the use of the conveying belt cleaner of the present invention, so that the height is gradually shortened according to the use frequency. In this case, the protrusion distance is determined based on the current height of the scraping block that has become shorter due to use.

  By the way, the conveyor belt cleaner of the present invention causes the scraping member to come into contact with the outer surface of the conveyor belt in an operating belt conveyor or the like, so that vibration is always applied during use. This vibration acts particularly strongly at the contact point with the positioning member in the scraping block, and may cause cracking or chipping in the scraping block at the contact point.

  Therefore, in the present invention, it is preferable to dispose a pedestal having a buffering property between the scraping block inserted into the groove and the positioning member so as to buffer the vibration applied during use.

  The pedestal may be composed mainly of a cushioning material such as foamed polystyrene or shock absorbing gel, or an elastic body such as a spring or rubber, and the pedestal is fixedly disposed on the bottom surface of the scraping block. Handleability is improved.

  The conveyor belt cleaner of the present invention further includes a biasing member that applies a biasing force toward the outer surface of the conveyor belt to the gantry and presses the end of the scraping member against the outer surface of the conveyor belt. preferable. That is, in the conveyor belt cleaner of the present invention, if the urging member is provided, a constant pressing force that presses the end portion of the scraping member against the outer surface of the conveyor belt is generated, and the scraping efficiency can be further improved. it can.

  The biasing member is not particularly limited as long as it can apply a biasing force toward the outer surface of the conveyor belt to the gantry. Specifically, for example, by fixing one end of the cable body to the gantry and attaching the cable body, the urging force toward the outer surface of the conveyor belt is applied to the gantry, or the gantry is elastic like a spring Examples include those that are supported by a body and that apply an urging force toward the outer surface of the conveyor belt to the gantry by the elastic force of the elastic body.

  The conveyor belt cleaner according to the present invention has the above-described configuration, and a scraping member is configured by inserting a plurality of scraping blocks into a groove provided in the frame and arranging them in an adjacent state. Therefore, the structure is simple and the assembling work becomes very simple.

  In addition, the scraping block constituting the scraping member is a block body having a constant thickness, a constant width, and a constant height. It is also possible to scrape and remove deposits firmly adhered to the surface.

  In the conveyor belt cleaner of the present invention, the plurality of scraping blocks held in the groove are individually supported by the positioning member, and the scraping block is changed to the groove by changing the support position of the positioning member. It can be remote from the bottom or close. As a result, the protruding distance from the groove opening end of the scraping member can be adjusted for each scraping block constituting the scraping member, so that there is a case where the conveyor belt is curved or uneven. However, it is possible to change the shape of the end of the scraping member so that the end of the scraping member can follow the outer surface of the conveyor belt.

  Further, in the conveyor belt cleaner of the present invention, even if the scraping block constituting the scraping member is worn by use, the worn scraping is set by setting the support position of the positioning member high according to the degree of wear. The protrusion distance from the groove opening end in the take block can be readjusted. Accordingly, the scraping member replacement cycle becomes longer, and the running cost is reduced.

  Furthermore, even if the wear of a part of the scraping block that constitutes the scraping member has progressed due to uneven wear, it is only necessary to replace the scraping block of the part where the wear has progressed or to change the arrangement of the scraping blocks. Since the scraping member can be reconfigured, the running cost is further reduced.
