the end plate 401 provides access to the respective lighting aisle sections and image passage sections that run within the dial, the here respective plane, plane-parallel optical plate 401 in front of the deflection prism 400, see FIG. 2 , that is, the illumination passage section and the imaging passage section in the respective peripheral section 200a, b, c terminates.
the orientation and arrangement of the optical components is carried out such that the line-shaped illumination section on the blade 41 extends with respect to its longitudinal extent substantially radially to the dial.
this illumination section runs centrally to the optical plate 401 and extends in the radial direction substantially over its entire optically effective extent.
the illumination section extends perpendicularly in the radial direction, i. tangential only over a fraction of the extension of the optical disk.
FIG. 3b shows the operating situation in which the coding, which is formed in the described embodiment as a data matrix code with a surface of 6.5 x 6.5 mm 2 , just within the optical disk 401. At the same time, the sheet 41 is sucked through the suction holes within the sections 211, 212. In the in FIG.
the 2D encoding 45 is located substantially completely inside the optical disk, even in this situation, only in the area of the center of the optical disk 401 is the area of the coding 45 imaged on the sensor surface 490, so that in the course of scanning the encoding the respective sections are imaged into different areas of the sensor surface, as the imaging gear section in the dial moves relative to the imaging section in the base device.
Figure 3c shows one in relation to the situation according to FIG. 3b a shortly after operating situation in which the edge 42 of the blade 41 is located just before the leading tip 201 of the section 200b.
the air intake holes in the section 212 act, so that the sheet is sucked in this area in the groove 205, so that the edge 42 in the direction of the Figure 3c is below the leading tip 201, so that it is received by this and further slides on the tip for covering the scholarlochbohrept 204, see FIG. 1b
the educalochbohronne are subjected to the vacuum as the suction holes, wherein a clocking of the sheet through the cover retaining negative pressure can be detected in the base device and processed as a count signal from a control device.
the coupling of the negative pressure i. the Saugluftzu arrangement
the base device rotating Zählefficiency 20 and the coupling of the illumination light in the respective illumination passage portion of the Zählusion and the image capture in or on the base means in that are provided on the respectively associated end faces of the base means and the counting disc areas for example Suction holes and imaging sections or lighting sections of the counting disc 20 with those of the base device 10 at predetermined times and intermittently to couple.
This coupling is accomplished by overlapping the respective areas such as holes by the relative rotation of the dial to the base at predetermined times, in the described embodiment the dial rotating at a uniform speed throughout the detection of the sheets of the stack.
FIG. 4 shows a with respect to the sheet stack 40 and the dial 20 for Figure 1c identical situation, with the base device removed. As a result, the provided on the upper end face of the dial 20 designs are visible.
FIG. 4 illustrated situation a situation is shown in which the top sheet 41 of the stack 40 has been picked up by the tip 201 of the peripheral portion 200b and at the top over the scholarlochbohrept 204 slides away, the underlying sheet first on the suction holes of the section 210th (please refer FIG. 3a ) and subsequently sucked by the suction holes of the section 211.
These suction holes are continued inside the counting disc 20 and end at its end face to the base device 10 in the suction holes 220 for the portion 210 and the suction holes 225 for the section 211.
both linear polarizers are on the respective optical insert 213, see Fig. 3a , fixed, which is arranged in a corresponding recess in the counting disc 20.
the peripheral portion indicated by reference numeral 245 includes a plurality of vacuum exhaust holes, which are effective particularly in the region of the groove 205 after the sheet is caught by the tip 201 of the peripheral portion 200c. Rotates the dial 200 from the position according to FIG. 4 Further, the tip 201 of the peripheral portion 200c detects the sheet, which then sweeps across the test hole bores 204 of the peripheral portion 200c to generate a count pulse.
the test bores 204 are fed in the described embodiment by the radially outer scholarlocheingang 250, which is arranged on the same radial circumferential line as the suction holes 225. Since the count generated by the cover of the striglochbohrungen 204 count is detected in the region of the base device by means of a pressure sensor, not shown , The counting disc also has a test hole output 255 on the end face to the base device.
each of the three peripheral portions 200a, b, c, the described connections on its front side to the base device, so counted at each peripheral portion of the leaves and on the preceding in the direction of rotation peripheral portion of the mounted on the respective sheet encoding is detected.
the counting disc in the described embodiment two trigger markers 260, 261, which with on, the Counter disk facing end face of the base device mounted photocells cooperate.
FIG. 5 now shows that of the dial according to FIG. 4 facing front side of the base device in a perspective view, so that with the reference to FIG. 4 described configurations corresponding configurations are recognizable.
the suction bore 105 corresponds insofar as a function of the rotational position of the hub with the suction holes 225 and the fürlocheingang 250.
the suction holes 106 correspond to the suction holes 220 and 240, the scholarlochausgang 255 corresponding to the educalocheingang 110. Also visible are the front ends of the lighting gear section or ., its end plate 370 and the imaging gear section or its end plate 450th
the base device 10 also has an in FIG. 5 unspecified optical insert on.
the sleeve comprises a support to which the optical components of the illumination passage section and the imaging passage section of the base device are fastened, wherein the support is inserted into a provided recess of the base device.
FIG. 5 the two with the trigger markers 260, 261 on the front side of the dial according to FIG. 4 cooperating photocells 125, 126, whose outputs are used to control the image sensor 490.
trigger markings are not arranged on the counting disc, but on another component which is moved by the drive shaft.
the counting disc facing end side of the base device has a Running surface for the counting disc from a soft to this material, the optical end plates are deposited on the adjacent end faces of the base device and counting disc respectively to the tread inside, so as not to soil the optical window or even damage.
the scanning of the coding of the sheets of the stack is not realized on the underside of the counting disk, but on the upper side of the counting disk, ie at the in the FIGS. 1a-c visible end face of the counting disc.
counting disk as used in this application is to be interpreted generally as meaning a disk (turntable) which rotates relative to the base device and which is designed to differentiate or separate sheets adjacent to one another on the sheet stack, so that on or in the sheets of the sheet Stack codings or features provided optically detected and can be made available for further processing.
