Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a belt for a belt conveyor used for transporting an object, and more particularly to an improvement in a structure for preventing an object from falling down from a side edge thereof.

[0002]

[Prior art]

 As shown in FIG. 5, a conventional belt conveyor 50 has intermediate support rollers 52 and 53 arranged on a support 54 such that the center in the horizontal direction of a flat belt-shaped conveyor belt 51 is depressed at an intermediate portion between the rollers. The spill 55 prevents an object from spilling to the side, and furthermore, an iron plate 56 or plastic is disposed on both sides in an upwardly open state, and a rubber plate 57 is attached to the lower edge of the skirt 55 to further spill the object to the side. I was trying to prevent.

[0003]

[Problems to be solved by the invention]

 In the conventional belt conveyor 50 as described above, the skirt 55 can prevent the spillage of objects to the side at the time of new construction, but the rubber of the skirt 55 can be relatively quickly transferred while the debris and construction waste are being conveyed. The plate 57 is worn, and a gap is formed between the plate 57 and the conveyor belt 51, so that particles or small objects spill out from the gap during the conveyance. Recently, a lot of radio cassette and video cassette tapes have been mixed in the waste, and they are durable and often wrap around the shafts of the rollers 52 and 53, causing power loss and operation stoppage. The most important problem is that a person who sweeps spills sometimes gets caught in the driving belt conveyor 50, causing injuries or death.

The present invention has been devised in view of the above, and in the intermediate portion between the rollers, the granular or small object is completely prevented from spilling from the side, and also exhibits the function of preventing spilling around the roller. An object of the present invention is to provide a highly durable belt conveyor belt that can eliminate the need for cleaning of a spilled product, ensure the safety of workers, and efficiently transport a fluid.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a belt conveyor according to the present invention is used for a belt conveyor which is used by being laid around a pair of rollers at least one of which is a driving roller. A belt having, at the side edge of the belt, elastic ribs which stand in an inclined state at an intermediate portion between the rollers and flatten in a state of being prone around the rollers, and the elastic ribs are in an inclined state. It is characterized by having an auxiliary elastic member for assisting the standing restoring force.

Accordingly, a belt for a belt conveyor is fed by a driving roller and conveys various objects by an upper conveyor belt. In an intermediate portion between the rollers, elastic ribs on side edges of the belt are formed by elasticity. It is standing up, completely preventing spills from the sides of the conveyed goods, eliminating the need for cleaning of spilled objects, ensuring the safety of workers, as well as boombox and video cassettes mixed in the conveyed waste. This prevents the tape from sticking out and prevents winding around the roller shaft. In general, vertical ribs are pulled around the rollers around the periphery, causing cracks.However, the elastic ribs of the present invention are inclined and flattened down around the rollers due to the tension around the rollers. It does not apply as much force as a straight rib, and durability is greatly improved. Even when the roller becomes flat around the roller, a thicker portion is formed on the side edge, and the height is low, but the function of preventing spilling to the side is maintained. Therefore, especially for a fluid, the fluid can be efficiently conveyed without spilling laterally even around the driving roller which tends to be horizontal. When the elastic rib passes around the roller, it can stand up again by its elasticity. In addition, the elastic ribs maintain an upright restoring force even in a long-term continuous operation by an auxiliary elastic member that assists a restoring force standing up in an inclined state, thereby improving durability.

Further, the elastic rib has a cross section formed in a substantially “<” shape by an inclined standing piece and a horizontal piece connected to each other, and is inclined inward at a side edge of the flat belt. It can be easily and efficiently manufactured separately and adhered or welded in a state. It can be attached to conventional belt conveyors as well as new ones, and conventional products can be modified. In addition, since it stands up in a state inclined inward, the conveyed material can easily enter around the rollers, but the receiving effect is high.

[0008] Furthermore, the elastic rib has a cross section substantially in the shape of "<" formed by an inclined standing piece and a horizontal piece which are connected to each other, and is inclined outward to the side edge of the flat belt. It can be easily and efficiently manufactured separately and adhered or welded, and can be attached to conventional belt conveyors as well as new ones, and conventional products can be modified. In addition, since it stands up in a state of inclining outward, the receiving effect is slightly reduced, but flattening around the rollers is smoothly performed without conveyed articles.

The elastic rib is formed integrally with the side edge of the belt, and the attaching work by adhesion or welding is omitted, and the elastic rib has high strength.

[0010]

[Embodiment of the invention]

 Next, the belt for a belt conveyor of the present invention is applied to a waste conveyor belt conveyor, and will be described in detail below with reference to the accompanying drawings. FIG. 1 is a partial perspective view of a waste conveyance belt conveyor according to a typical embodiment of the present invention, FIG. 2A is a cross-sectional view of the upper side of a belt between rollers of the belt conveyor, and FIG. FIG. 3 is a cross-sectional view of the upper side of the belt around the rollers of the conveyor, FIG. 3 is a cross-sectional view of the upper side of the belt between the rollers of the waste conveying belt conveyor of another embodiment, and FIG. 4 is the rollers of the waste conveying belt conveyor of still another embodiment. FIG. 4 is a cross-sectional view of the upper side of the belt between them.

1 and 2, a waste conveyor belt conveyor 1 according to a typical embodiment of the present invention includes a conveyor belt (hereinafter, conveyor belt) around a driving roller 11 and a driven roller (not shown). 20) and is circulated in the rotation direction R of the drive roller 11. In the intermediate portion between the rollers, as shown in FIG. 5 of the conventional example, the roller is supported by an intermediate support roller (not shown) so that the central portion is slightly lowered. Further, as in the prior art, a skirt 35 is provided in which an iron plate 36 and plastic are disposed on both sides in an upward opening and a rubber plate 37 is attached to a lower edge portion thereof so that a large object can be transported. It is configured.

The conveyor belt 20 is bonded or welded on both side edges thereof such that the elastic ribs 21 stand in a state in which the elastic ribs 21 are inclined inward at a middle portion between the rollers and lie down around the rollers. I have. The elastic rib 21 is separate from the conveyor belt 20, and is made of a material such as rubber that is resistant to repeated deformation and is horizontally connected to the inclined standing pieces 21A that are connected to each other so that the cross section becomes substantially “<”. It is formed by injection molding or the like so as to be composed of the piece 21B. Since the inclined standing piece 21A of the elastic rib 21 stands in an inwardly inclined state at the intermediate portion between the rollers, the receiving effect is high. However, although the conveyed material easily enters between the inclined standing piece 21A and the horizontal piece 21B, the conveyed article is prevented by using the skirt 35 in combination, so that the flat deformation around the roller does not interfere. The elastic rib 21 is provided with an auxiliary elastic member 25 having a cross section of substantially "<" made of buckle steel for assisting a restoring force for elevating the inclined erecting piece 21A in an inclined state. The upright restoring force is maintained.

The inclined standing piece 21A of the elastic rib 21 is located at an intermediate portion between the rollers, and stands up due to its elasticity, thereby completely preventing the conveyed material from spilling to the side and performing cleaning work for the spilled material. It is unnecessary and the safety of workers can be ensured. In addition, the radio-cassette and the video cassette tape mixed into the transport waste are prevented from protruding, so that winding around the roller shaft can be prevented. Generally, the vertical ribs are cracked due to tension applied to the peripheral portion around the roller. However, since the inclined standing piece 21A is inclined, the vertical rising piece 21A is placed on the horizontal piece 21B in a state where it is turned down by the pulling of the peripheral portion around the roller. It does not apply as much force as the overlapping and vertical ribs, and has good durability. In addition, even if it is flat around the roller, it forms a thick part on the side edge and keeps the function of preventing spilling to the side although the height is low, and therefore, especially for flowing objects, Even around the drive roller 11, which tends to be horizontal, no spillage occurs laterally, and the flow of the fluid can be efficiently performed. When the inclined erecting piece 21A passes around the roller, it can be erected again by its elasticity.

As shown in FIG. 3, in another embodiment, the elastic ribs 21 are also formed to have a substantially “<” cross-sectional shape, and the inclined upright pieces are provided on the side edges of the flat conveyor belt 20. 21A is bonded or welded to the outside by a horizontal piece 21B in a direction inclining outward. Since the inclined standing piece 21A stands up in a state of being inclined outward, the receiving effect is slightly reduced. However, even without the skirt 34 or the like, the conveyed material does not enter and the flattening around the roller is performed smoothly. As shown in FIG. 4, in still another embodiment, the elastic rib 21 ′ is formed integrally with the side edge of the conveyor belt 20 ′ in an inclined state, so that the attachment work by adhesion or welding is omitted, and the strength is improved. Is high. The belt conveyor of the present invention can be used not only for conveying waste, but also for conveying various objects.

[0015]

[Effect of the invention]

 As is apparent from the above description, according to the belt for a belt conveyor of the present invention, (1) the belt conveyor is stretched around a pair of rollers at least one of which is a driving roller. The belt for the belt conveyor is provided with a driving roller, which has elastic ribs on the side edges thereof, which are erected in an inclined state at an intermediate portion between the rollers and flattened in a prone state around the rollers. The upper belt transports various objects, but in the middle between the rollers, the elastic ribs at the side edges rise up due to their elasticity, completely preventing the conveyed items from falling off the sides. This eliminates the need to clean up spills, ensures the safety of workers, and wraps around the roller shaft by preventing the radio-cassette and video cassette tape mixed into the transport waste from sticking out. A it can be prevented.

(2) Since the elastic ribs are inclined, the elastic ribs are flattened in a state where they are turned down by pulling the peripheral portion around the roller, and the elastic ribs are not subjected to excessive force as compared with the vertical ribs, and are durable.
