- Non-contact protective mechanisms for the field of automatic roll placement provided on a reel changer which ensures a permanent protection of the secured area even with different roll diameters and the removal of residual sleeve containers.
- Due to the "outward widening" of the security area a wide variety of roll sizes can be handled without the need for restrictions due to safety clearances due to physically limited passage widths (eg adjacent units, building walls or columns, etc.)
- a width of access to the security area may be significantly increased in order to be able to comply with distance measurements to fixed edges in any case, but in this context, a particularly high-performance protection device at the access boundaries, ie in the access area, is of particular advantage.
- a sensor subsystem allows recognition of permissible passages, rollers and / or means of transport, and accordingly inhibits a reaction
- a second sensor subsystem is permanently "armed" and is directed at the passage of, for example, people
- the reaction of the protective device may be such as to initiate countermeasures, such as, for example, stopping
- a camera or camera-like device can be provided as a sensor system, by means of which a detection result obtained via an evaluation device is checked for admissibility.
- the protective device in addition to a protective function, also has an integrated muting function, which saves the expense of setting up an additional device for the muting function.
- This muting function of the sensor system itself can be achieved by distinguishing objects permitted and prohibited by the pattern of passage through the plurality of light beams, in particular by means of a suitable circuit and / or implemented
- Evaluation routine For example, it may be provided as a rule that - at least in a height section to be considered - only a contiguous area of superposed light beams may be interrupted simultaneously.
- the muting function thus allows a time-limited deactivation of parts of the
- Protective device or the entire protective device Preferably, the penetration of objects is allowed without the safety device to operate.
- the light beams are evenly spaced from each other and are inclined to the horizontal, wherein the light beams in other embodiments, also horizontally extending and a surface of the light grid can be arranged inclined to the vertical.
- a plane formed by light rays of the light grid can be inclined in an advantageous embodiment to a vertical, z. B. parallel to be hedged border of the access level.
- An incoming object in the transport direction with a vertical leading edge interrupts in this way the light beams one after the other in a continuous sequence.
- Slight variations in vertical alignment such as may be caused by winding faults, are caused by skew
- the “resolution” or the “tolerance” can be optimized here by the distance of the light beams and / or the strength of the inclination.
- Circumstances can be adjusted.
- steps of other methods can be carried out in between and it is possible, depending on spatial conditions and just free storage locations to proceed flexibly, for example, to perform linear movements before or after pivotal movements or linear
