Abstract: The invention relates to a sorting method for sorting objects, characterised by at least the following sorting steps: a) first sort run, in which objects are input onto parking sections of a first block of parking sections; b) second sort run, in which objects are transferred from the first block of parking sections to a second block of parking sections; and c) third sort run, in which objects are transferred from the second block of parking sections back to the first block of parking sections. The invention also relates to two alternative types of sorting installations which are suitable for carrying out the above sorting method, and to a sorting system which combines a plurality of these sorting installations.

Abstract: A suspension conveyor installation having rollers (4) which are selectively linked to a drive chain (16) by driver elements (13). The driver elements (13) are arranged as link plates on the pins (15) of the drive chain (16) so as to be pivotable with respect to each other about vertical axes perpendicular to the drive chain (16), thereby allowing the driver elements (13) to flex when rounding sharp turns in the suspension conveyor installation. The bottom edge of each driver elements (13) has an oblique lifting ramp 18 at its leading edge, a glider surface (19) adjoining the lifting ramp (18), and a driver recess (20) adjoining the glider surface (19).

Abstract: A suspension conveyor system with a multiplicity of rollers traveling on a rail network. A load attachment device with a hook designed to carry the hook of a clothes hanger is pivotally mounted on each roller in order to permit loading and unloading of the hook. The load attachment device also has an inclined slide ramp thereon opposite the opening of the hook which engages a leading ramp on a rail parallel to the path of conveyance at a loading/unloading station to pivot the load attachment device into a raised position in which the hook of the clothes hanger to drop through an opening between the slide ramp and onto the rail. When the slide ramp contacts one of a row of clothes hanger already deposited on the rail the load attachment device will pivot upward slightly to lift the end of the hook from the rail thereby releasing the hook of the clothes hanger.

Abstract: A suspension conveyor and sorting installation for the sequential sorting of individually conveyed objects. The installation includes two parallel conveyor paths arranged side by side and driven in opposite directions. Independent roller devices carry objects to be sorted and are conveyed by getting coupled to pushing members. Stop members stop the roller devices on associated conveyor paths, so that the roller devices can be uncoupled from the pushing members. A transfer apparatus is provided between the conveyor paths at a distance from their respective ends, for transferring the objects conveyed along the conveyor paths, from one conveyor path to the other conveyor path. Finally, a sorting controller, connected to the transfer mechanism and the stop members, controls the sorting of the conveyed objects such that the objects are sorted while remaining on the conveyor paths.

Abstract: A suspension conveyor comprises two conveyor circuits which circulate in opposite directions. The circuits are arranged on opposite sides of an additional conveyor path, where the conveying directions of the path and circuits are the same at their point of coincidence. Roller devices for carrying objects (a, b, . . . , n), are entrained by a pushing or pulling mechanism of the conveyor circuits. A controllable switch arranged between the conveyor circuits, for transferring the objects individually from one of the conveyor circuits to the other, is adapted to transfer the objects selectively from the conveyor path to either of the conveyor circuits and vice versa. The switch is also adapted to selectively allow the objects to travel past the switch without leaving the respective conveyor circuit in which the objects are present. The suspension conveyor is additionally a sorting installation for sorting numerous different individually conveyed objects (a,b, . . . n).

Abstract: A suspension conveyor system includes a rail network and a roller apparatus adapted to travel along it. The rails comprise at least two sectional running girders each with upper and lower running surfaces and at least one sectional support girder. The running girders extend side by side and are interconnected through strips spaced from each other so as to form a guide slit. The roller apparatus has a carriage comprising two bearing rollers and which is supported by the upper surfaces of the girders. The lower end of the roller apparatus is equipped with a load carrier, arranged below the guide slit. Below the bearing rollers, at least two stabilizing rollers are arranged on either side of the travelling axis of the bearing rollers. The roller apparatus further includes two lateral guide rollers spaced from each other in the travelling direction of the apparatus.

Abstract: A suspension conveyor system (1) comprising a conveyor device (3) rolling along a track rail (2) with straight track sections, curves and/or switches. The conveyor device includes a bearing member (11), which is provided with a support member (17) for the articles to be conveyed, and at least two casters (12a, 12b) arranged on the bearing member (11) symmetrically with respect to each other with regard to a plane of symmetry (13). The track rail (2) has at least one running track (7) along which one of the casters (12a, 12b) rolls.

Abstract: There is described a method of sorting a plurality of individually conveyed articles in a suspension-type conveyor apparatus, wherein the articles circulate along a first conveyor circuit in unsorted fashion and are transferred from there individually and automatically to at least a second conveyor path and arranged in groups. To make such a method more simple and less troublesome, it is suggested that the second conveyor path be designed as a second conveyor circuit along which the articles circulate and that an automatically switchable shunt be provided between the first and second conveyor circuits. Both, the first conveyor circuit and the second conveyor circuit, are closed loop and reversibly driven.

Abstract: A conveying unit for a suspension conveying system having an elevated rail which unit includes two roller supports for rolling on a rail and a supporting element connected to the roller supports, on which the object to be conveyed are to be disposed. A coupling is provided in order to be able to couple the conveying unit to other conveying unit. In order to be able to better adapt the conveying unit to special operating conditions the coupling is arranged directly on the roller support.
