An apparatus for placing in order the servicing sequence of storey calls of an elevator system, comprising storage elements for storing the storey calls, storage transmitter means for controlling the storage elements, a scanner for scanning the storage elements, and a respective further storage element operatively associated with each storey being serviced. Each such further storage element has a first input connected with the related storage element serving to store a storey call and its output is connected by means of a logic circuit with a blocking device blocking infed and stored storey calls during a servicing period corresponding to at least one revolution of the scanner. A second input of each such further storage element is connected with the output of a release device freeing the blocked storey calls after completion of a servicing period in order to accomplish storey servicing during the following servicing period. A first input of the release device is connected with an output of the scanner delivering information at the start of a scanner revolution and its second input with the output of the blocking device and with a switching device controlling the scanner drive. Release of the stored storey calls and thus initiation of a new servicing period first is accomplished when there appears at the output of the blocking device information signaling the completion of the storey calls released during the preceding servicing period.

Apparatus for placing in order the servicing sequence of storey calls of

An apparatus for selecting an elevator cabin at a transportation installation, especially an elevator system, for direct travel of an elevator group, controlled by means of a group control, possesses additional storey call transmitters and storey call storages. The storey call storages are connected with a call blocking device having infed thereto a first signal train or sequence produced during scanning of the storey call storages. The call blocking device possesses further inputs, to which there is infed information blocking already allocated calls, so that at its output there appears a second signal train or sequence no longer containing the allocated calls. This output is connected with a respective input of call allocation devices operatively associated with the elevators. The call allocation devices are operatively interconnected with one another by means of a switching circuit. Upon the occurrence of a coincidence signal of an elevator which is ready to service a storey call, the related call allocation device is prepared for the call allocation. Upon subsequent occurrence of a storey call there appears at the output of the call allocation device a control signal which triggers the direct travel.

Apparatus for selecting an elevator cabin

An apparatus for selecting a storey call at a transportation installation, especially an elevator system, which contains storey call storages and a scanning device which continuously scans the storey call storages and produces a signal sequence containing the stored storey calls, as well as possessing a selector which signals the location of the elevator cabin. Upon coincidence of the elevator cabin location and the scanner position there is produced a coincidence signal which, in conjunction with an information signal signalling the operating state of the elevator cabin, is delivered to a selector circuit. Both signals act by means of a first NOR-gate and a storage upon a second NOR-gate of the selector circuit. Storey call signals which have been selected from the signal sequence produced by the scanner device and ordered in accordance with the time sequence of their input are delivered to a further input of the second NOR-gate. If there simultaneously appear the information signal signalling the travel readiness of the elevator cabin and the coincidence signal, then at the output of the second NOR-gate there appears a control signal which, in the direction of travel of the scanner device, corresponds to the storey call situated closest to the coincidence signal.
