  • the suction head on the feeder A corresponding printing press and the deflection via sensor means have detecting control element, through which this device of an operator in an intuitively simple way to the desired sheet format or can adjust the necessary height.
  • the invention is applicable for those to be set to the sheet format Stops or bow brakes.
  • the element to be adjusted can be handled by the operator Control element as a handle, as a to be moved in the direction of movement Ring, designed as a lever to be pivoted, as a button to be pressed his.
  • the sensor system assigned to the control element, that of the sensor system downstream evaluation device and those generated by the evaluation device Control commands for driving the element are in the for a simple Usability trained way. As above several times indicated it can be force sensors through which the The strength of the deflection, for example of a handle, can be detected as an operating element and via which the evaluation unit connected downstream of the sensors then Control commands for a faster / slower procedure of the Element or for moving the element at a constant speed however with additional drive power (overcoming resistances or the weight of the element) can be generated. This can be provided be the breakaway torque of the element to be adjusted by the drive generate so that the operator then only a minimal force to move of the element
  • the motor-driven element is formed as a vertically movable slide protection 1, which is not in front of a further illustrated danger point, for example a printing unit Printing machine is arranged.
  • This known slide protection 1 can vertical by an operator in the manner explained below be moved, i.e. from, for example, a lower one that safeguards the danger point Position in an upper and in particular also selectable position be moved.
  • the sliding protection 1 as the motor-driven element has on its lower End of a handle 2 that can be handled by the operator, which has a Swivel joint is connected to the slide protection 1.
  • the direction of movement of the Slip protection 1 is by the double arrow, the pivotable movement of the Handle 2 marked relative to the slide protection 1 by the curved double arrow.
  • the slide protection 1 can be moved by a motor via an associated drive 3, the transmission elements to be provided between the drive 3 and the sliding protection 1 for example in the form of traction means, chains or the like. Not shown are.
  • the drive 3 can be, for example, an electric motor act that moves the slide protection 1 via traction means (chains), it can but also act as a pneumatic cylinder that can be operated with compressed air which the sliding protection in by appropriate pressure medium is movable in a predetermined manner.
  • a control S is arranged upstream of the drive 3, via which the corresponding signal and / or pressure medium application of the drive 3 for moving the sliding protection 1 in a predetermined manner.
  • the pivotally mounted with respect to the slide protection 1 handle 2 is a Assigned to sensor 4, by means of which one is caused by an operator Operation of the handle 2 is detectable.
  • sensor 4 it can are preferably a force sensor through which the strength the deflection of the handle 2 relative to the slide protection 1 can be determined.
  • the handle 2 over the above Swivel joint is pivotally mounted with respect to the slide protection 1 and the handle 2 spring means are assigned such that the handle 2 in actuation-free state a basic position - for example at right angles to Slip protection 1 - occupies.
  • the sensor 4 is then preferably used as a distance measuring system formed by which the deflection of the handle 2nd Corresponding signals can be generated relative to the basic position.
