DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steeply inclined vertical conveyor for transporting loose articles between double belts, and more particularly to reducing the running resistance of the double belt and extending the life of the belt. It relates to a steep and vertical conveyor that can be used.

[0002]

2. Description of the Related Art In general, in a conveyor for transporting loose articles, a steeply inclined / vertical conveyor for steeply transporting or vertically transporting loose articles between double belts in order to save space is known. FIG. 4 shows a vertical conveyor which is folded in a substantially Z-shape from a horizontal direction to a vertical direction for vertical conveyance.

[0003] As shown in the figure, the conveyor 1 is composed of a belt 4 running between pulleys 2 and 3 and a belt 7 running between pulleys 5 and 6. The belts 4 and 7 constitute a double belt that transports the loose material A therebetween. Each of the belts 4 and 7 is folded in the horizontal and vertical directions via intermediate pulleys 8 and 9.

[0004] The conveyor 1 is provided with a vertical transport section 11 for vertically transporting the bulk material A. As shown in FIGS. 4 and 5, the vertical transport section 11 has the belt 4 and the belt 7 at both ends in the width direction. 5 and 6, the end rollers 12 are staggered in the conveying direction with both belts 4 and 7 interposed therebetween, as shown in FIGS. The belts 4 and 7 are arranged at equal pitches to guide the running of the belts 4 and 7. In this manner, both ends of the belts 4 and 7 in the width direction are overlapped and sealed, so that the loose material A sandwiched between the belts 4 and 7 can be conveyed.

[0005]

As shown in FIG. 6, the holding force for holding the loose material A is obtained by the end rollers 12 overlapping and sealing both ends of the belts 4 and 7 in the width direction. Since the belts 4 and 7 are held only by the rigidity, there is a disadvantage in the related art that the holding force of the loose material A at the central portion sandwiched between the belts 4 and 7 is weakened.

Further, each end roller 12 provided along both belts 4 and 7 is fixedly supported by a roller mount 13, and both ends in the width direction of both belts 4 and 7 are overlapped and sealed. In addition, to guide the running of the belts 4 and 7, the end rollers 12 are arranged at a short pitch. For this reason, the arrangement of the end rollers 12 is increased, and the running resistance of the belts 4 and 7 is increased.
, The number of repeated bending increases, and the life of the belts 4 and 7 is shortened.

The present invention has been made to effectively solve the above problems.
