20130248716 | DEVICE FOR CAPTURING AND DETECTING OF OBJECTS - Systems and methods are disclosed for the detection and identification of objects, wherein an illumination device emits polychromatic light in the infrared range, creating a light curtain, or an essentially two-dimensional area of light in the X and Z axis. The light from the light curtain and light reflected or transmitted by an object in the light curtain is imaged, via aperture-imaging optics, onto an aperture that is in the optical path and behind the aperture-imaging optics. The aperture is an elongated opening extending along the Z axis. A wavelength-dispersive device, such as a grating, diffracts light admitted by the aperture wavelength-dispersively in a diffraction direction along the Y axis. An image sensor detects the diffraction image and generates image signals which are analyzed to identify the materials comprising the object. An output signal may be generated in response to the material identified. | 09-26-2013 |

20100308151 | Winding Machine and Method for Controlling a Winding Machine - The invention relates to a method for controlling a winding machine for winding a continuously fed winding material on bobbin tubes to wound packages. The winding machine comprises two driven spindles. A traversing device holds a traversing guide. The traversing guide is driven for a traversing movement, whereas the traversing device is driven for a changing movement in a changing direction transverse to the traversing movement. A control device controls both the traversing movement and the changing movement. The movement of said traversing device and said traversing guide is controlled for guiding the winding material from a package wound at a first spindle via a fixed transfer device to the second spindle. The winding material is caught by a catching device associated with the second spindle. The winding material is cut by a cutting device wherein the cutting movement is caused by a rotation of the second spindle. | 12-09-2010 |
20130313354 | WINDING MACHINE - The invention relates to a winding machine, on which, in alternation, a wound package is wound in a winding position of a spindle, while at the same time a completely wound package is removed from another spindle. With winding machines according to the prior art, the completely wound package must be removed quickly before the other wound package has reached a critical diameter to avoid a collision of their lateral faces. According to the invention, a shifting device shifts the completely wound package before or during the winding process of the wound package such that the axial extensions of the wound packages have no overlap. The collision of the wound packages can thus be prevented as the diameter of the wound package increases, whereby a more compact design with a smaller spacing of the spindles is made possible and an operator has more time to remove the completely wound spool. | 11-28-2013 |
