| 摘要 |
The invention relates to a device (100) for laterally positioning a plate element (20, 20') in a machine for processing plate elements, comprising a detection lever (130) that is hinged about a horizontal axis and is capable of carrying out a downward movement from a high position to a low position. A first end (132) of the detection lever (130) is arranged so as to come into contact, in the low position, with an upper surface of the plate element (20, 20'). A second end (133) of the detection lever (130) is provided with a target (135) that interacts with a position detector (140) in order to generate a signal dependant on the thickness of the plate element (20, 20') and on the number of plate elements (20, 20') present in the region of the first end (132) of the detection lever (130). |
