Abstract

The method involves monitoring dangerous zones with a sensor (40), which is suitable for identification of objects penetrating into the zones. The sensor is suitable to differentiate between human body part and articles, where the sensor is three-dimensional camera. The object is affected by the condition of the zone based on the operating condition of a printing machine and the identification of the object. An independent claim is also included for a device for implementing a method for securing a dangerous zone in a printing machine.

Description

technical field

[0001] The invention relates to a method and a device for securing a danger zone in a machine, wherein the danger zone is monitored with at least one sensor which is suitable for detecting objects entering the danger zone and for establishing a connection with a machine control. Background technique

[0002] Methods and protective devices are already known by means of which machine safety can be ensured, wherein a distinction can be made as to which objects are allowed to enter and which are not. Such a device is known from US 2003 / 0164447 A1 and secures the hazardous area of ​​a metal processing machine. The open part of the danger zone of the metalworking machine is here mainly secured by means of a light barrier device, which is able to distinguish between permissible workpieces and impermissible body parts of the operator. The discrimination takes place in that when the workpiece passes through the light grid, only one beam is blocked due to its small th...
