Accumulation conveyor

The invention concerns a conveyor for packages, especially a conveyor for flexible packages such as newspapers, textiles or sacks. The conveyor includes a plurality of sequential, parallel and spaced rollers, which form a conveying surface and are perpendicular to a direction of conveyance. Along their length, the rollers have alternating cylindrical sections and narrowing sections. The narrowing sections narrow to both sides of a highest point along the length of the roller toward the cylindrical sections. A plurality of continuous belts are guided around groups of sequential rollers and run in the direction of conveyance to bridge gaps between the spaced rollers. The belts are positioned around the narrowing sections at the maximum diameter thereof. In order to create a conveyor for packages that is less prone to disturbances, it is preferred that the diameters and the widths of the narrowing sections and the cylindrical sections of the rollers be selected in relation to a width and/or thickness of the belts, such that when a belt is deflected by a package from the highest point of the narrowing section toward the cylindrical section, the belt will lose contact with the package as the package remains on the neighboring belts or the highest point of the roller. The belt thus can independently return to the highest point of the narrowing section, as the belt is driven by its continuing contact with the narrowing section, before the belt is deflected to the neighboring narrowing section and after the package is transported further by the conveyor.

Conveyor for articles with wave-shaped rollers

This invention relates to a conveyor apparatus or roller train with a series of conveyor stations, the support rollers of which can be optionally driven or shut off. To create an economical and reliable roller train with a separation and storage function, each conveyor station of the roller train has its own drive motor with a switchgear unit and the several switchgear units are connected together for control purposes into a cascade so that only the first switchgear unit of the cascade is connected to a higher-voltage switch cabinet.

Conveyor apparatus

A principal or main conveyer cooperates with branch conveyers in that diverting wheels are provided for pivoting to the left or right as well as for lowering and raising, for obtaining selectivity of diverting.
