Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor used for vertically transporting small articles such as powders, granules, pellets and foods.

[0002]

2. Description of the Related Art Conventionally, a conveyor of a bent vertical conveyance in which flat conveyance surfaces are provided at both ends of an upper and lower conveyance surface generally uses a bucket suspended between chain belts. The bucket can be easily rotated for cleaning, so the front and back sides can be easily cleaned.However, when using a belt conveyor for vertical conveyance of the conveyor, loosen the tension of the rollers at both ends and pull out the belt. It is common to go.

[0003] However, in the system in which the tension of the roller of the conveyor is loosened, it is not possible to expect a large slack of the belt. It becomes unsanitary.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an apparatus which can easily and reliably clean the belt of a vertically conveyed belt conveyor by greatly loosening the belt.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a bent belt conveyor provided with a flat conveying surface at each of both ends of an upper and lower conveying surface, and in a frame inside a corner between the upper and lower conveying surfaces of the belt and the flat conveying surface. The detachable corner plate has a press roller provided along the inside of the belt along the curve of the belt.
The outer vertical side of the corner plate and the vertical support of the frame can be freely fitted by a guide rod and a guide hole fixed to each other, and the outer horizontal side of the corner plate and the horizontal frame of the frame. Are made freely attachable by a female screw and a male screw provided to each other.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the illustrated embodiment. In a bent belt conveyor 3 provided with flat conveying surfaces 2 and 2 'at both ends of an upper and lower conveying surface 1, respectively, the upper and lower conveying surfaces 1 and 2 A substantially triangular corner plate 6 removably provided inside the corner frame 5 of the flat transfer surface 2 of the above-mentioned plane has a holding roller 7 provided inside along the curve of the belt 4, .. Are provided, and a vertical side portion 8 outside the corner plate 6 and a frame are provided.
The vertical support 9 of the frame 5 can be fitted by a guide rod 10 and a guide hole 11 fixed to each other, and a lateral side 12 outside the corner plate 6 and a horizontal stand 13 of the frame 5 The female screw 14 and the corresponding male screw 15 provided respectively with each other make it possible to freely tighten.

The male screw 15 is preferably provided with a clamp lever 16 so that tightening and loosening operations can be easily performed.

[0008]

The present invention is embodied as described above. When using the present invention, the clamp lever 16 is loosened and the female screw 15 is used.
Then, the corner plate 6 is lifted up together with the belt 4 to remove the guide rods 10 and the guide holes 11, and pulled out to make the belt 4 hang down, thereby cleaning the front and back of the belt 4.

[0009]

As described above, according to the present invention, in a bent belt conveyor provided with a plane conveying surface at each of both ends of the upper and lower conveying surfaces, the belt can be freely attached to the upper and lower conveying surfaces of the belt and inside the frame of the corner of the plane conveying surface. The corner plate has a pressing roller provided inside along the curve of the belt, and the outer vertical side of the corner plate and the vertical support of the frame can be fitted freely by the guide rod and the guide hole fixed to each other. The outer side of the corner plate and the horizontal base of the frame can be freely tightened by the female screw and male screw provided to each other, so the work of attaching and detaching the guide rod and the guide hole, and the work of tightening the female screw and male screw The work can be done easily and reliably because the user can look directly at the belt, and a large cleaning space is provided, so that the belt can be easily, quickly and reliably cleaned.
