<p>The control device serves to increase the efficiency of a machine, which is subdivided into individual sections, for producing objects from glass. Each section has a shaping device (14). Each shaping device is assigned a section computer (13) which produces control signals for the shaping device (14) every working cycle of the machine as a function of a control program stored in a storage device (16) and of time switching values. The relative position of each working step within the working cycle is defined by a switch-on time and a switch-off time. These switching time values are stored in the section computer (13). The difference between the switch-on time value and switch-off time value is the dwell time available for carrying out the respective work step. This dwell time can be changed with the aid of a control console (21) by manual displacement of one or of both switching time values. The section computer (13) is programmed in such a way that it automatically prevents a change in the dwell time if a negative dwell time which is in practice not possible were to be produced by this change. <IMAGE></p> |
