Abstract

PROBLEM TO BE SOLVED: To increase conveyance quantity with a filling factor of 70% or higher and convey on a curve with a diameter of 300 times or more and a plane round angle of 40 degrees or larger and to prevent drop of loads. SOLUTION: A belt makes a deep U-shape (or V-shape) and upper end of the belt 15 has some expanse accordingly to increase the filling factor. The belt is supported by a belt side face holding roller 13 and a carrier roller 11. By holding the belt side face at end parts, the belt is prevented from folding inside. Inclination inside a conveyer frame 10 prevents sliding up of the belt. Holding of the U-shaped belt enables a horizontal conveyance even with a small round shape without drop of loads. Since this shape allows folding into right and left at several places, the conveyer can be united in a place such as a narrow valley where many conventional belt conveyers are needed and connections with several conveyers are dispensed with.

Description

Detailed Description of the Invention

Inside the truss frame, the upper (belt carrying side) belt shape has a rounded lower part, and the upper part is held in a U-shape that opens to the outside with rollers. The belt cross section is also molded in the lower part of the inner part of the truss frame in a shape similar to the above with only the lower part of the U-shape or V-shape. Belt The U-shaped or V-shaped belt on the load carrying side returns to normal after the head side unloads it once, and the belt scraper holds the belt vertically and holds it with the belt scraper. Remove dust adhering to the belt. By making the belt on the return side U-shaped or V-shaped, you can run smoothly on a curve. The belt is composed of multi-point carrier rollers and side holding rollers in order to maintain the U-shape and V-shape, and the carrier roller, the frame and the rollers are inclined inward. Therefore, it is possible to prevent the belt from rolling up.

FIELD OF THE INVENTION This invention is in the field of belt conveyors.

2. Description of the Related Art Conventionally, it has been impossible for a conveyor equipment of a belt conveyor using a flat belt to bend and convey the sheet in a flat direction. A conveyor in which the belt itself is wrapped in a cylindrical shape can be bent in the horizontal direction, but the wrapped belt pipe requires a bending curve of 300 times or more the diameter. There are many restrictions on the amount of conveyance, with a pipe diameter filling rate of 70% or less. Belt pipe conveyors cannot be installed with a flat radius angle of 40 degrees or more.

Since the conventional conveyor cannot be bent and conveyed in the horizontal direction, it is necessary to connect with several conveyors, and a head chute and a skirt are required. There was a drawback of spilling. This invention is one conveyor that requires several or many conveyors to prevent cargo spillage, and can be freely leveled on top of it without cargo spillage and can be bent left or right at any number of 90 degrees. Noted that the curve is also transported.
Also, I thought that it would be possible to convey a small radius on a horizontal curve.

[Means for Solving the Problems] What the inventor thought and thought up in order to solve the above problems. 2 pieces of paper from the middle
Notice that it is possible to fold it and bend it. The belt is bent long, the lower part of the belt has a semi-circular rounded shape, and the upper part of the belt has an outward spread. By holding the side of the belt at the end, the upper end of the belt was prevented from trying to fold inside. The inventor prototyped a 1200-width belt with a captain of 150 rice and a left curve of 150 US and a right curve of 100 US are, and succeeded in trial operation.

BEST MODE FOR CARRYING OUT THE INVENTION The belt has a deep U shape. Have a spread at the top of the belt. The lower part of the belt supports the belt with several carrier rollers, and the upper ends of the belt support the belt with side holding rollers. Like the luggage transport side, both the luggage transport side belt and the return side belt hold the U-shaped belt so that even a small radius in the horizontal direction does not cause the load to spill, and the belt meanders slightly and rubs up ( Rolling phenomenon) was prevented.

Embodiments of the present invention will be described with reference to FIGS. 1 and 4. 15, belt 11 is a carrier roller for supporting the belt, and 13 is a belt for supporting the upper side of the belt. The belt is advanced by the holding roller in the direction of the arrow, and the head pulley of 16 is moved to the rear side in the tail direction.

[Effects of the Invention] By making the belt into a deep U-shape (V) and folding the belt on both the transport side and the return side, the horizontal small rounded portion does not spill and the trough section is large. It has the effect of carrying a large amount of luggage. The baggage transport side belt and the return side belt are the same as the transport side.
By holding the U-shaped (V) belt, even a small radius in the horizontal direction does not cause the load to spill, and the meandering of the belt is small, so that the belt is prevented from rubbing (rolling phenomenon). One of several conveyors is now possible. Can also bend flat surfaces. In addition, the transport amount is also large. The horizontal bending angle can be 90 degrees or more. There are many luggage loading cross-sections, and a lot of bulk and transportation charges.

FIG. 5 is a cross-sectional view of a belt 2, a return roller 3, and an end surface roller conveyor. The upper surface indicates the transport side and the lower surface indicates the return side of the belt. The belt 1 is held on the upper surface of the slanted flat roller 2 in an oblique state, and since tension is applied to the belt, the end surface 3 holds down the movement of climbing to the upper surface. The movement of the belt descending to the lower surface is supported by 3 and suddenly supported. You can bend the inner curved belt.
