Abstract
A conveying roller, a conveyor device, and an inclined conveyor for objects. A conveying roller comes into contact with an object and moves the object, the conveying roller including: a core member and a plurality of blade-shaped pieces, the blade-shaped piece being elastically deformable and being provided around the core member.
Claims8
A conveying roller that is rotated with power, thereby applying force to an object on the conveying roller to move the object, the conveying roller comprising:
- a large-diameter portion and a small-diameter portion,
- the large-diameter portion comprising:
- a core member;
- and
- a deformation unit elastically deformable and provided around the core member,
- the deformation unit comprising:
- a cavity;
- and
- an annular part that comes into contact with the object,
- the cavity being provided between the annular part and the core member to allow the annular part to be elastically deformable.
A conveyor device comprising conveying rollers arranged in parallel, the conveyor device rotating the conveying rollers with power, thereby applying force to an object on the conveying rollers to move the object,
- wherein the conveying rollers include:
- a first conveying roller;
- and a second conveying roller adjacent to the first conveying roller,
- wherein the first conveying roller includes:
- a first large-diameter portion;
- and a first small-diameter portion, and the second conveying roller includes:
- a second large-diameter portion;
- and a second small-diameter portion,
- the first large-diameter portion being located at a position corresponding to the second small-diameter portion,
- the first small-diameter portion being located at a position corresponding to the second large-diameter portion, and
- wherein an inter-shaft distance between the first and the second conveying rollers is shorter than a diameter of the first large-diameter portion and that of the second large-diameter portion,
- the first and second large-diameter portions each comprising:
- a core member;
- and
- a deformation unit provided around the core member,
- the deformation unit comprising:
- a cavity;
- and
- an annular part that comes into contact with the object,
- the cavity being provided between the annular part and the core member to allow the deformation unit to be elastically deformable.
