[0035] FIG. 2 is a schematic representation of an operating unit and of a display unit according to an exemplary embodiment of the present invention.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0036] The same or similar components in different figures are given the same reference signs. The representations in the figures are schematic.

[0037] FIG. 1 shows a control system 100 for a functional section I, II, III of a paper processing device 140. The control system 100 has at least one safety-monitoring camera 110, 120, 130, which is disposed in the functional section I, II, III, such that a functional region of the functional section I, II, III can be captured by means of the safety-monitoring camera 110, 120, 130. An operating unit 101 of the system 100 is designed to operate the functional section I, II, III. The image data of the at least one safety-monitoring camera 110, 120, 130 can be selected with the operating unit 101. A display unit 103 is configured to display the selected image data, such that a user allows or blocks the operation of the functional section I, II, III on the basis of the displayed image data.

[0038] Moreover, a safety device 102 can be provided, which is coupled to the safety-monitoring camera 110, 120, 130 and the operating unit 101, wherein the safety device 102 receives image data of the safety-monitoring camera 110, 120, 130. The safety device 102 is configured, such that the safety device 102 allows the operation of the functional section I, II, III by means of the operating unit 101 or blocks the operation of the functional section I, II, III by means of the operating unit 101 on the basis of the received image data of the safety-monitoring camera 110, 120, 130.

[0039] The paper processing device 140 is configured to process paper, more particularly cardboard layers and cardboard packaging. Along the processing process of the paper processing device 140, for example, cardboard packaging can be produced in multiple layers, cut to size and/or printed. The paper processing device 140 has more particularly multiple functional sections I, II, III, wherein each functional section I, II, III defines one processing step in a functional region in each case. A functional section I, II, III comprises, for example, a stacking device (for stacking flat cardboard packaging elements or for taking individual cardboard packaging elements from a stack), a laminating device (for bonding multiple layers of paper or cardboard layers), a paper feed device and/or a drying device.

[0040] The operating device 101 is configured to run and operate the functional section I, II, III and accordingly the paper processing device 140. In this connection, the operating device 101 is installed at a distance spatially from the functional section I, II, III and for example the paper processing device 140. The operating device 101 can for example transfer control data by wire or wirelessly to the paper processing device 140, in order to transmit control commands or to receive status data or control data from the paper processing device 140. The operating unit 140 has an input element, for example, a keyboard.

[0041] The safety-monitoring camera 110, 120, 130 or multiple safety-monitoring cameras 110, 120, 130 of a group are assigned to a functional section I, II, III. The safety-monitoring camera 110, 120, 130 captures particular safety-related regions into the functional section I, II, III. For example, the safety-related regions may represent maintenance regions, maintenance installations or other movable machine elements in the functional section, which must be handled or maintained by an operator during maintenance or repair. The safety-monitoring cameras 110, 120, 130 monitor the safety-related regions of the functional section I, II, III and capture image data (single images or film sequences or live streams) and transmit the image data to the operating unit 101 and/or the safety device 102.

[0042] The user analyzes and evaluates the captured image data. Moreover the safety device 102 can analyze and appraise the captured image data. On the basis of the captured image data, the user blocks the operation of the functional sections I, II, III by means of the operating unit 101. Alternatively or additionally, the safety device 102 can block the operating unit 101 or give it clearance.

[0043] On the basis of the image data, if the safety device 102 for example identifies a person in the functional section I, II, III, the safety device 102 blocks the operating unit 101. This means that for example any activation of the processing process in the functional section I, II, III by the operating unit 101 is impossible. If the operating unit 101 is located at a distance from the functional section I, II, III, any remote control of the functional section I, II, III is thereby prevented. Alternatively, on the basis of the image data, the safety device 102 can identify, whether the safety-monitoring cameras 110, 120, 130 are working correctly. If the safety device 102 detects that the safety-monitoring cameras 110, 120, 130 are not working correctly, the safety device 102 blocks the operating unit 101 likewise, in order to prevent overhasty and unnecessary termination of the process in the functional section I, II, III.

[0044] The control system has at least one process camera 112, 122, 132, which is disposed in the functional section I, II, III, such that a work process 111, 121, 131 in the functional section I, II, III can be captured by means of the process camera 112, 122, 132. The process camera 112, 122, 132 is coupled to the display unit 103 or the operating unit 101, such that, based on the captured work process 111, 121, 131, this can be terminated by the user by means of the operating unit 101. Moreover the process camera 112, 122, 132 can be coupled to the safety device 102, such that, based on the captured work process 111, 121, 131, this can be terminated by means of the safety device 102.

[0045] The process camera 112, 122, 132 captures more particularly process-related images of the work process 111, 121, 131. For example the position of a paper web or the unrolling behavior of the paper web from the roll can be captured with the process camera 112, 122, 132. If, on the basis of the captured image data of the work process 111, 121, 131, the safety device 102 detects that, for example, the path of a paper web is not running correctly, the safety device 102 can terminate the work process 111, 121, 131 by itself.

[0046] While the process camera 112, 122, 132 captures images of a work process 111, 121, 131, in comparison with this, the safety-monitoring camera 110, 120, 130 captures the working space in the functional region, which can be accessed by a person. In this connection, it is entirely possible that a process camera 112, 122, 132 functions as safety-monitoring camera 110, 120, 130 and vice versa.

[0047] The image data of the at least one safety-monitoring camera 110, 120, 130 can be selected with the operating unit 101, wherein a display unit 103 is configured to display the selected image data. The display unit 103 and the operating unit 101 are configured e.g. integrally as touch-screen.

[0048] FIG. 2 shows an exemplary representation of the operating unit 101 and of the display unit 103. A desired functional section I is selected by means of the operating unit 101. The display unit 103 displays the functional section I of the paper processing device 140. Based on the selected functional section I, the operating unit 101 is configured to display on the display unit 103 the functional region of the functional section I captured by means of the safety-monitoring camera 110 using camera shots A to F of the safety-monitoring cameras 110 from the functional section I. Thus the paper processing device 140 and accordingly its functional sections I, II, III can be depicted on the display unit 103 (e.g. a touch-screen). By means of finger pressure on the operating unit 101 (e.g. a display region of a corresponding functional section on the touch-screen) a user can select the same. Then the images A to F of the safety-monitoring cameras 110 and/or of the process camera 112 on the display unit are depicted on the display unit 103. Moreover the operating state of the work process 111, 121, 131 from the functional section I can be depicted on the display unit 103. Furthermore, it can be displayed to the user, whether the safety-monitoring camera 110 is supplying image data, which allow operation of the operating unit 101 or not.

[0049] In addition it should be pointed out that, comprising does not exclude any other elements or steps and one or a does not exclude a plurality. Moreover it should be pointed out that features or steps described with reference to one of the above exemplary embodiments can also be used in combination with other features or steps of other afore-described exemplary embodiments. Reference signs in the claims are not to be viewed as a restriction.
