Abstract
A separating device (10) for separating a tubular flat material (1) having an actual tube width (1.1), comprising at least one longitudinal separating unit (20) for removing a first edge region (2) and a second edge region (3) of the flat material (1) is provided. In addition, a separating method (100) for separating a tubular flat material and to a system (70) having a separating device (10) is provided.
Claims17
A separating device for separating a tubular flat material having an actual tube width, comprising:
- at least one longitudinal separation device for separating or severing a first edge region and a second edge region of the flat material,
- wherein
- an auxiliary separation device is provided which can be brought from an auxiliary rest state into an auxiliary separation state, the auxiliary separation device being deactivated in the auxiliary rest state and being activated in the auxiliary separation state, wherein the auxiliary separation device has at least two auxiliary separation components which are configured to separate a first auxiliary edge region, which includes the first edge region, and a second auxiliary edge region, which includes the second edge region, from a center region of the flat material in the auxiliary separation state, the center region being arranged between the first edge region and the second edge region of the flat material,
- wherein a sensor device is provided being configured to generate signals depending on a deviation of the actual tube width from a target tube width of the flat material,
- wherein a first drive device is provided which is configured to bring the auxiliary separation components from the auxiliary rest state into the auxiliary separation state at least if the actual tube width is smaller than the target tube width or if the separation of the edge regions is interrupted, and
- wherein a control device is provided and in communication connection with the sensor device and the first drive device, the control device being configured to control the first drive device to automatically and laterally move the auxiliary separation components from a position out of the flat material into the flat material on the basis of the signals from the sensor device received over the communication connection, in order to change the state of the auxiliary separation components from the auxiliary rest state to the auxiliary separation state,
- wherein the auxiliary separation device is arranged downstream of the sensor device with respect to a transport direction of the flat material.
A system with a separating device for separating a tubular flat material having an actual tube width, with at least one longitudinal separation device for separating or severing a first edge region and a second edge region of the flat material, wherein an auxiliary separation device is provided which can be brought from an auxiliary rest state into an auxiliary separation state, the auxiliary separation device being deactivated in the auxiliary rest state and being activated in the auxiliary separation state, wherein the auxiliary separation device has at least two auxiliary separation components which are configured to separate a first auxiliary edge region, which includes the first edge region, and a second auxiliary edge region, which includes the second edge region, from a center region of the flat material in the auxiliary separation state, the center region being arranged between the first edge region and the second edge region of the flat material, for separating a tubular flat material into at least two flat webs, at least a first winding device and a second winding device being arranged downstream of the separating device in a transport direction of the flat material, so that at least one of the flat webs can be wound on a winding coil, which can be mounted on a winding holder of the winding devices,
- wherein a sensor device is provided being configured to generate signals depending on a deviation of the actual tube width from a target tube width of the flat material,
- wherein a first drive device is provided which is configured to bring the auxiliary separation components from the auxiliary rest state into the auxiliary separation state at least if the actual tube width is smaller than the target tube width or if the separation of the edge regions is interrupted, and
- wherein a control device is provided and in communication connection with the sensor device and the first drive device, the control device being configured to control the first drive device to automatically and laterally move the auxiliary separation components from a position out of the flat material into the flat material on the basis of the signals from the sensor device received over the communication connection, in order to change the state of the auxiliary separation components from the auxiliary rest state to the auxiliary separation state,
- wherein the auxiliary separation device is arranged downstream of the sensor device with respect to a transport direction of the flat material.
