Definitions

  • a method for operating a high-speed mail processing machine for processing mixed mail with different thicknesses and different dimensions is known, see EP 0 503 502 B1.
  • the method includes the steps of moving each piece of mail to a weighing station, weighing it, and then printing the value stamp. These steps are activated and controlled by a drive control in accordance with several sensors.
  • the sensors are distributed across the machine, some of which are optical sensors.
  • the method also causes a special sensor processor to access the sensors and to inform the drive controller of their state after they have been activated beforehand.
  • the access step includes periodically executing a master cycle so as to access each sensor in a first group during each cycle and access each sensor in a second group only for some, but not all, cycles.
  • the sensor data are written into a RAM which the control can access.
  • An arrangement for pre-separating print carriers is also known, see DE 196 05 017 A1, in which letters are placed one behind the other as a stack of letters standing on one edge and the letters are fed laterally away from the stack of letters to a separating device.
  • the letters are arranged between a spring-loaded pressure bracket and at least one drive roller and a guide plate inclined slightly backwards.
  • the base for the letters and the guide plate are mutually orthogonal.
  • a device for separating printing media in particular letters, according to DE 198 36 235.8 and FIGS. 1 to 4 was found.
  • the letters A are also stacked one behind the other in the separating device B with an edge on a lower guide plate 2 between a spring-loaded pressure bracket 21 and drive roller combinations 3, 4 and a guide plate 1 which is inclined slightly backwards.
  • the drive rollers with their cylindrical enveloping surfaces protrude through openings in the guide plate 1 and the letters A are individually transported away laterally by the former.
  • the separating device B is divided into a pre-separating area I with two drive roller combinations 3, 4 in the start-stop mode and into a separating area II with elements 6, 7, 77 for separating with continuous passage.
  • a sensor 10 for printing medium detection and ejection means 9 in the form of a pair of ejection rollers 91, 92.
  • the elements 6, 7, 77 for singulation consist of a drive belt combination 6, a driven counter-roller combination 7 adapted to this and an upstream sliding lever combination 77 also adapted.
  • the sensor 10b is arranged in the area of the counter roller combination 7 and is electrically connected to a drive 5 for the two drive roller combinations 3, 4 in such a way that the drive 5 is switched on in each case when the end of the print carrier is detected.
  • the ejector roller pair 91, 92 consists of a driven ejector roller 91 and an driven ejector roller 92.
  • the driven ejector roller 91 is fastened on a rotatable axis 911 behind the guide plate 1 and partially protrudes through an adapted opening thereof.
  • the driven ejection roller 92 is fastened on a likewise rotatable axis 921 in front of the guide plate 1, see in particular FIGS. 2 and 3.
  • the axis 921 is rotatably supported on a rotatably spring-mounted support lever 93.
  • a common drive 8 is provided for the drive belt combination 6, the counter roller combination 7 together with the slide lever combination 77 and the ejection roller pair 91, 92.
  • the purpose of the invention is to improve the performance properties.
  • the invention has for its object the letter throughput in a Separating device of the type described above to the Throughput of the successor devices, in particular a subsequent one Postage meter to adapt.
  • the invention is based on the consideration that in the franking machine a minimum distance from the leading edge of the letter to the leading edge of the letter following letters must exist, the longest franking imprint plus print head width plus a security measure. So that is at least the distance given for small short letters. For larger or longer letters, the distance is from front edge to front edge inevitably greater than this minimum distance. In this case, it depends on the distance between the long letter and the following letter as small as possible maintain or achieve the greatest possible throughput.
  • This problem is solved by the invention by controlling the transport speed in the individual passage areas of the letters in the separating device. Depending on the transport speed of the successor device, the transfer speed is adapted to this. This prevents congestion in the downstream device from this side.
  • the transport speed is set higher in the separation area than the transfer speed until a letter has reached the ejection area. This corresponds to the accelerated transport in the separation area. This serves to increase the throughput in general and to reduce the distance between successive letters in particular.
  • the transport speed in the separating area is set to less than or equal to the transfer speed as long as a letter is in the ejection area. This corresponds to normal transport in the separation area. This prevents the formation of jams in front of the discharge area.
  • the transport speed in the pre-separation area is set greater than the transfer speed and greater than the increased transport speed in the separation area, as long as there is no letter in the entrance area of the separation area. This corresponds to the accelerated transport in the pre-separation area. This also serves to increase the throughput in general and to reduce the distance between successive letters in particular.
  • the transport speed in the pre-separation area is set to less than or equal to the normal transport speed in the separation area when a letter has reached the entrance area of the separation area and there is no further letter in front of the ejection area. This corresponds to normal transport in the pre-separation area. This prevents the formation of jams in the entrance area of the separation area.
  • the transport speed is set to zero in the pre-separation area as long as there is a letter in the entrance area and in the other areas of the separation area. This corresponds to the stop or idle operation in the pre-separation area. This prevents jamming or multiple deductions.
  • the transfer speed to the successor device that is the transport speed that is generated with the ejection roller pair, is continuously monitored. It is always kept lower than or equal to the transport speed set in the downstream device, but somewhat higher - approximately 10% - than the transport speed in the initial area of the separation area, that is the transport speed generated with the elements for separation.
  • the transport speed which is generated with the drive rollers during accelerated transport, is set correspondingly higher - approximately 30% - than the transfer speed in the separation area.
  • the letter is scanned in the entrance area of the singling area and immediately after the singling in order to derive corresponding control signals for the drive in the pre-singling area and in the singling area in connection with further scanning results.
  • the letter is scanned in the ejection area of the separating device in order to derive control signals for the pre-separating area, the separating area and the subsequent device.
  • the sensor 10a is expediently used as a reflex sensor executed. This sensor 10a determines whether the letter A in this area has entered or is still in this area Area.
  • an optical sensor 10b is arranged in a correspondingly adapted opening of the rear guide plate 1 immediately after the drive belt combination 6 or counter roller combination 7.
  • the sensor 10b is also expediently designed as a reflex sensor. This sensor 10b is used to determine whether a letter A is present in this area.
  • the ejection roller pair 91, 92 is arranged at such a distance after the counter-roller combination 7 that even the shortest possible letter A is already detected by the former before it has left the latter.
  • a sensor 13 for measuring the transport speed of the letter A is arranged on the rotatable axis 921 for the driven ejection roller 92 at this point.
  • the sensor 13 is designed as an encoder, the output signal of which is compared by means of the evaluation circuit 15 with a signal corresponding to the transport speed in the downstream device 16, and a signal for controlling the common drive 8 in the separation area II and the drive 5 in the pre-separation area I is derived therefrom, see also Fig. 4 and 5.
  • a letter A which passes the ejection roller pair 91, 92, is linearly moved by the driven ejection roller 91 by frictional engagement and also transmits its movement synchronously by frictional engagement to the resiliently adjustable driven ejection roller 92 as a rotary movement.
  • the driven ejection roller is firmly seated on the axis 921.
  • a sensor 14 is also provided, which is arranged in the ejection area for the letters A immediately before or after the line of contact between the ejection rollers 91, 92 in the guide plate 1.
  • the sensor 14 is advantageously also designed as a reflex sensor. With the help of this sensor 14, it is recognized whether a letter A has reached or left the ejection area and, in addition, the current transport speed in the subsequent device 16 is queried via the evaluation circuit 15.
