A method and apparatus for operating a filling machine having a stationary part, and movable part provided with filling elements, whereby each filling element has associated therewith at least one electrically actuatable valve and a signal emitter which is actuated by the filling material rising in a filling vessel or container briefly pressed into engagement on the filling element for filling thereof. For the filling elements the operating data are stored in a common electronic control unit connected with the terminals of the signal emitter as well as with the actuating device of the valves of the filling element; during a cycle phase of a timing cycle encompassing all filling elements and running for a predetermined period of time, by means of this electronic control unit, with the filling elements switched ready for operation, the operating conditions of the signal emitter or emitters and of the valve or valves of each filling element are scanned, whereby the predetermined time period amounts to a fraction of the time necessary for the completion of a filling process; and that each time a timing cycle is finished, there begins a new timing cycle, and the data of the operating conditions obtained by the cyclic scanning are stored in the electronic control unit and are compared with the preset operating data, and a possibly necessary signal is emitted to the valve or valves.

An arrangement for controlling a bottle filling machine having a stationary part, a rotating part provided with filling elements, each filling element having operatively associated therewith at least one valve and one signal emitter, the latter being actuated by the filling material rising in a container which is briefly pressed onto the respective filling element for filling purposes, comprising: a registering and storage device which is synchronously connected step-for-step with the circulation path of said rotating part of said filling machine in the manner of a shift register, and which has a number of register locations and storage means which are at least adjustable to the number of filling elements in circulation; a sensing device arranged on said rotating part of said filling machine and provided with feeler elements which respond to breakage of a container to be filled, and enter an appropriate marking in said registering and storage device; a discharge element for discharging containers from said filling machine; an ejection device located in the region of said discharge element which, when actuated, ejects a container from a row of containers leaving said filling machine; a counting chain of relays with that number of counting locations having storage elements which corresponds to an integral multiple of the number of filling elements in circulation, increased by the necessary advancing steps between the arrangement of said sensing device and said ejection device, said counting chain of relays being connected to said registering and storage device for taking over information; and a switching device, said counting chain of relays being connected to said switching device for emitting switching pulses in the advancing step spacing between said sensing and ejection devices, said switching device serving to actuate said ejection device.
