Abstract
A weighing conveyor having an increased weighing accuracy. This conveyor includes a conveyor apparatus 3 for transporting an article X to be weighed, a load detector 5 for detecting the weight of the article X to be weighed, and a housing 7 for accommodating the load detector 5, in which a fixed end 5b of the load detector is connected with the housing 7 and a free end 5c thereof is connected with a support member 120 for supporting the conveyor apparatus 3, and the support member 120 protrudes outwardly of the housing 7 from a bottom surface thereof.
Claims26
A weighing conveyor, which comprises a conveyor apparatus for successively transporting articles to be weighed, a load detector for detecting a weight of the articles to be weighed that are successively transported by the conveyor apparatus, and a housing for accommodating the load detector, wherein a fixed end of the load detector is connected with the housing and a free end thereof is connected with a support member for supporting the conveyor apparatus, said support member protruding outwardly from a bottom surface of the housing.
A conveyor apparatus, wherein when a frame structure is bent, an endless transport belt can be mounted on or removed from at least one pair of rollers supported by the frame structure, wherein a bending fulcrum of the frame structure lies at a location on one side of a line of extension, connecting respective axes of rotation of the rollers together when the frame structure is not bent, adjacent one of runs of the transport belt, and wherein there is provided a stop member for inhibiting the frame structure from being bent towards the other of the runs of the transport belt.
A conveyor apparatus of a type wherein when a frame structure is bent, an endless transport belt can be mounted on or removed from at least one pair of rollers supported by the frame structure, said conveyor apparatus comprising a drive source for driving one of the rollers;
- a pulley mounted on a drive shaft of the drive source;
- a pulley mounted coaxial with one of the rollers;
- an endless drive transmitting belt trained between and around the pulleys, wherein a bending fulcrum of the frame structure lies at a location on one side of a line of extension of respective axes of rotation of the pulleys, when the frame structure is not bent, adjacent one of runs of the drive transmitting belt;
- and a stop member for inhibiting the frame structure from being bent towards the other of the runs of the drive transmitting belt.
A weighing conveyor for weighing a weight of an article to be weighed while the article to be weighed is transported, said weighing conveyor comprising a conveyor apparatus for transporting the article to be weighed and having a transport surface laid horizontally;
- a drive source for driving the conveyor apparatus, and a load detector for supporting the conveyor apparatus and the drive source and for detecting the weight of the article to be weighed that is supported and transported by the conveyor apparatus, in terms of up and down displacement thereof, an axis of rotation of the drive source being arranged parallel to a direction of such displacement.
