Embodiment Construction

[0019] figure 1 A printing press 10 is shown, which consists of a sheet feeder 11 , two printing units 12 and a sheet delivery 1 . In the sheet feeder 11 , the sheets 17 are sucked and separated from the sheet feed stack 14 by means of a suction head 18 and then transported via a suction table 19 to the printing unit 12 . The sheets 17 are conveyed by the printing unit 12 by means of the transfer cylinder 16 and are conveyed in the printed state to the delivery 1 . In this case, the sheet transport from the last printing unit 12 up to the delivery pile 13 in the delivery 1 is carried out by a delivery chain 15 which grabs the sheet 17 on at least one side and It is deposited into the delivery pile 13 . The printing press 10 is controlled during operation by an electronic machine control 5 , which converts the input of the operator.

[0020] Both the sheet feeder 11 and the delivery 1 are a great source of danger, since there is a great risk of injury to the operating person...

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...
