An article diverging sorting apparatus includes a multiplicity of spherical sorting rollers arranged in plural rows both in a conveyance direction aligned with an article conveyance path or line and in a crosswise direction transverse to the conveyance direction over a plurality of consecutive conveyance areas along the article conveyance line. The spherical sorting rollers contained in every conveyance area are simultaneously turned about respective vertical axes to move between a first position aligned with the conveyance direction and a second position aligned with a sorting direction deflected at an acute angle from the first position such that the angle of deflection of the spherical sorting rollers becomes greater in a downstream one of the conveyance areas than in an upstream one of the conveyance areas. An article is gradually turned or deflected toward the sorting direction as it is conveyed by the spherical sorting rollers. The article is delivered from the downstream conveyance area onto a diverging belt conveyor during which time the orientation of this article is corrected by an orientation correcting member until the article assumes a position aligned with a conveyance direction of the diverging belt conveyor. With this construction, the diverging sorting apparatus can orient articles toward the sorting direction even when the articles are fed at relatively small intervals.
Disclosed are conveyors and methods for making the conveyors. In one embodiment, a conveyor comprises a modular conveyor belt that includes a plurality of mat-top chains having a plurality of cavities and a plurality of first rollers disposed in the cavities of the mat-top chains. The conveyor further includes at least one second roller that operatively couples to the first rollers such that the first rollers rotate as the conveyor belt travels along the second roller. The invention can also be construed as providing the method for conveying objects. The method can comprise the steps of driving a modular conveyor belt in a direction of belt travel; rotating a plurality of first rollers disposed into the modular conveyor belt in a manner in which slippage of the first rollers is reduced; and conveying objects on the modular conveyor belt using the rotating first rollers.
A switch conveyor including a modular conveyor belt or mat divided into longitudinal lanes of rollers. All the rollers in a lane are arranged to rotate about axes oriented in a common direction. The rollers in an adjacent lane are arranged to rotate about axes oriented in a different direction. A switch mechanism underlying the conveyor belt along a carryway selectably contacts the bottom side of the belt or mat with bearing surfaces that rotate the rollers in selected lanes along the carryway to propel conveyed articles in one direction or another.
A singulating conveyor for aligning a mass of conveyed articles into a single file. The conveyor includes a first centering conveying zone in which one or more roller-top conveyor mats direct conveyed articles sidewise toward a side or the center of the zone. The rollers on which the articles ride rotate about axes oblique to the conveying direction to provide a sidewise component of motion to the articles. The articles are received downstream in a second separation zone, in which the articles are sped up in the conveying direction to separate them into a single file. The conveyor mats can be realized as endless conveyor belts in motion or as stationary mats overlying a moving belt contacting and rotating the rollers.
A deviation device for a conveyor which defines a conveying plane (22), e.g. a driving roller path (23), for deviating conveyed goods, e.g. containers, comprising a row of rollers (7) arranged on a separate carrier (5) common to them, the carrier being arranged in a frame (3) so as to be adjustable in height therein, the rollers having an associated driving roller (4) in common, characterized in that the frame (3) accommodating the carrier (5) is a separate module frame of a deviation module element (1; 1') in which the driving roller (4) is mounted below the carrier (5) with the rollers (7), and in which, preferably, furthermore a basic carrier (3B) is fixed between the roller carrier (5) and the driving roller (2), which basic carrier carries a lifting drive (2) for the roller carrier (5).
In one embodiment, a conveyor system includes a conveyor belt having a plurality of conveyor belt rollers configured to divert objects on the conveyor belt, and a drive mechanism that engages the conveyor belt rollers, the drive mechanism being configured to drive the conveyor belt rollers, the drive mechanism being adjustable such that the conveyor belt rollers can be selectively driven in a first angular direction and a second, opposite angular direction so that objects can be selectively diverted to either side of the conveyor belt at a desired diverting angle.
