Abstract

Provided are: a transport conveyor that makes it possible to reduce the maintenance frequency thereof; and a V-shaped transport mechanism including the transport conveyor. The transport conveyor includes: a first pulley that rotates about a first rotating shaft; a second pulley that rotates about a second rotating shaft; a pair of frames that support the first rotating shaft and the second rotating shaft; and a conveyor belt wound around, and extending between, the first pulley and the second pulley. At least one frame of the pair of frames is configured as an offset frame including offset supports, the offset supports supporting the first rotating shaft and the second rotating shaft at respective positions that are located inward of both ends of the conveyor belt in a width direction thereof.

First claim

The invention claimed is:

1 . A transport conveyor comprising:
a first pulley that rotates about a first rotating shaft; a second pulley that rotates about a second rotating shaft; a pair of frames that support the first rotating shaft and the second rotating shaft; and a conveyor belt wound around, and extending between, the first pulley and the second pulley, wherein at least one frame of the pair of frames is configured as an offset frame including offset supports, the offset supports supporting the first rotating shaft and the second rotating shaft at respective positions that are located inward of both ends of the conveyor belt in a width direction thereof, the pair of frames include:
a pair of frame bodies including respective outer surfaces that are orthogonal to the first rotating shaft and the second rotating shaft; and
a pair of tension adjusters that are connected to the pair of frame bodies and that adjust tension of the conveyor belt by adjusting a distance between the first pulley and the second pulley,
the pair of tension adjusters are provided outward of the respective outer surfaces of the pair of frame bodies in the width direction of the conveyor belt, and of the pair of tension adjusters, the tension adjuster provided on the offset frame side is positioned between one of the offset supports and an end of the offset frame side of the conveyor belt in the width direction thereof.

2 . The transport conveyor according to claim 1 , wherein
each of the first pulley and the second pulley includes:
a main pulley that is disposed between the pair of frame bodies; and
an auxiliary pulley that is, in the width direction of the conveyor belt, disposed outward of one of the offset supports of the offset frame.

3 . A V-shaped transport mechanism in which two transport conveyors are arranged such that, as seen in a transporting direction, transport surfaces of the respective two transport conveyors are in a V shape, wherein
one transport conveyor of the two transport conveyors is the transport conveyor according to claim 1 , and in the one transport conveyor, the first rotating shaft and the second rotating shaft are arranged in an inclined manner, such that the offset frame is positioned at a lower elevation than the other frame.

4 . The V-shaped transport mechanism according to claim 3 , wherein
the one transport conveyor is arranged such that an end of the offset frame side of the one transport conveyor in the width direction of the conveyor belt is positioned over the conveyor belt of the other transport conveyor of the two transport conveyors.

5 . A V-shaped transport mechanism in which two transport conveyors are arranged such that, as seen in a transporting direction, transport surfaces of the respective two transport conveyors are in a V shape, wherein
one transport conveyor of the two transport conveyors is the transport conveyor according to claim 2 , and in the one transport conveyor, the first rotating shaft and the second rotating shaft are arranged in an inclined manner, such that the offset frame is positioned at a lower elevation than the other frame.

6 . The V-shaped transport mechanism according to claim 5 , wherein
the one transport conveyor is arranged such that an end of the offset frame side of the one transport conveyor in the width direction of the conveyor belt is positioned over the conveyor belt of the other transport conveyor of the two transport conveyors.
