Abstract

A conveying and sorting apparatus has tilting motors which switch tilting conveyor units which are supported so as to be able to swing about a support shaft that is parallel with the conveying direction, between a horizontal conveying orientation and a tilted orientation; and a conveyor driving motor which drives the conveying conveyors and that are provided to the tilting conveyor units. The support shaft has a single interlocking transmission shaft having a length which covers the entire area of the plurality of tilting conveyor units. The conveying conveyors of each tilting conveyor unit are interconnected by the interlocking transmission shaft. One conveyor driving motor is provided for the plurality of tilting conveyor units supported by the interlocking transmission shaft. This single conveyor driving motor drives the conveying conveyors via the interlocking transmission shaft.

First claim

What is claimed is:

1. A conveying and sorting apparatus comprising:
a plurality of tilting conveyor units arranged in a row in a conveying direction, each of the tilting conveyor units supported so as to be swingable about a support shaft parallel to a conveying direction of a conveyed object between a horizontal conveying orientation and a tilted orientation for discharging the conveyed object laterally with respect to the conveying direction of the conveyed object by gravity, a conveyor driving motor arranged to drive conveying conveyors for the conveyed object provided to each of the tilting conveyor units, and a tilting motor arranged to switch each of the tilting conveyor units between the horizontal conveying orientation and the tilted orientation;
the support shaft is formed of a single interlocking transmission shaft having a length covering an entire area including the plurality of tilting conveyor units; and
the conveying conveyors of all of the tilting conveyor units in the area are interlockingly coupled to the interlocking transmission shaft, and the one conveyor driving motor is installed for the area, and the one conveyor driving motor drives the conveying conveyors of all of the tilting conveyor units in the area via the interlocking transmission shaft.

2. The conveying and sorting apparatus according to claim 1 , wherein;
a single drive shaft interlockingly coupled to the conveying conveyors is provided to each of the tilting conveyor units so as to be arranged above the interlocking transmission shaft in an orientation parallel to the conveying direction of the conveyed object, and the single drive shaft and the interlocking transmission shaft are interlockingly coupled by a winding transmission means;
bearings for supporting the tilting conveyor unit so as to be swingable about the interlocking transmission shaft are attached to each of the tilting conveyor units, and a passive rotating body relatively rotatably fitted to the interlocking transmission shaft at a position adjacent to each bearing is fixed to each bearing; and
a rotational force of an output shaft of the tilting motor arranged corresponding to each of the tilting conveyor units is transmitted to the tilting conveyor unit via a winding transmission tool stretched between a transmission rotating body attached to the output shaft and the passive rotating body.

3. The conveying and sorting apparatus according to claim 2 , wherein;
the plurality of tilting conveyor units is divided into a plurality of assemblies with two adjacent tilting conveyor units as one assembly, and one support shaft whose both end portions are supported via bearings supports the two tilting conveyor units in each of the assemblies, and the support shafts are interlockingly coupled to each other by a joint between two adjacent assemblies to form the interlocking transmission shaft; and
the one conveyor driving motor is arranged outside the assembly located at one end, and two of the tilting motors driving the two tilting conveyor units in each of the assemblies are installed such that the transmission rotating bodies are reverse to each other in a front-rear direction at both left and right sides of the interlocking transmission shaft in plan view.
