Definitions
- the invention relates to a method and an arrangement for recognizing overlapped flat mail items in a transport path for mail items transported upright in succession.
- a problem that occurs with separating devices consists in so-called double deduction errors which result from the fact that in addition to the consignment to be deducted from a stack, another consignment is also deducted.
- the undetected double deductions are of particular importance, since they increase the misdistribution rate due to reading errors of the automatic address recognition, but can also result in a consignment jam with consignment destruction.
- movable mail items are temporarily deflected perpendicular to the conveyor.
- the presence of overlapped mail items is then detected by evaluating the quick-response behavior of the mail items (EP 0 650 911 B1). Since there may be a different offset of the overlapped mail items, the deflection must take place both on the front side of the mail item and on the back side of the mail item, which results in increased effort.
- Another disadvantage is the mechanical stress on the mail items during the deflection.
- Another deficiency of this solution is that the offset of the rear edges must not be less than a minimum value (approx. 10 mm).
- DE 12 10 601 A describes a method and an arrangement for recognizing mail overlaps, with edges on both sides of the transport path being determined by means of measuring devices for edge detection.
- US Pat. No. 5,505,440 A shows a method and an arrangement for recognizing consignment overlaps, the total length of a consignment or overlapping consignment being measured, subsequently overlapping consignments being shifted towards one another and the total length being then measured again.
- a solution has also become known (DE 101 42 331 Cl), in which after the detection of edges on both sides of the transport path and the determination of the distances of the detected edges from the leading front edge measured in each case with a light barrier on the long sides of the mail items, is affected at different transport speeds without falling below the minimum gaps. Then the distances of the edges from the leading front edge are measured again. If the distance changes, a double deduction is detected.
- an overlap is determined by means of edge detection. From WO 01/89 724 AI and JP 09-020 438 AA it is known to determine overlapped mail items within a transport stage by means of a speed sensor arranged on one side of the transport path. Transport paths are known from DE 102 12 024 A1, in which the nominal speed of successive transport stages increases in the transport direction.
- the object of the invention is to detect overlapped narrow mail items in a transport path for mail items transported upright one after the other as early and reliably as possible.
- At least two transport stages are arranged one after the other in the transport path, the nominal speed of the subsequent transport stage in the transport direction being higher than the nominal speed of the upstream transport stage.
- the speed of the transported items is measured by scanning in front of a subsequent transport stage up to a maximum distance smaller than the shortest agreed length of the item by means of two sensors arranged on both sides of the transport path, and the measurement results are evaluated if a sensor measures a speed that is different from the nominal speed of the subsequent transport level only deviates by a specified low value.
- a sensor measures a speed that is different from the nominal speed of the subsequent transport level only deviates by a specified low value.
- an overlap is detected when the speeds of the two sensors measured at the same time are different, the lower measured speed deviating from the higher speed by a fixed value.
- the overlapped mail items are determined very early and reliably by measuring the mail item speed.
- the evaluation of the measurement results only begins after a defined delay time after the speed jump measured by a sensor to a speed that deviates from the nominal speed of the subsequent transport stage only by a specified small value.
- FIG. 1 shows a schematic plan view of two transport stages and two speed sensors arranged between them
- FIG. 2 shows a schematic plan view of two transport stages, two larger pressure rollers being located at the beginning of the second transport stage
- each sensor 3, 4 is realized here by means of a roller running on the surface of the mail item and driving a tachometer generator. The output signal of the tachometer generator corresponding to the speed is transmitted as a measurement signal to an evaluation device.
- the speeds of the sensors 3, 4 are monitored. If the difference between the highest measured speed value and the speed of the subsequent transport stage 2 is smaller than a defined small limit value, it is assumed that the shipment 3 is transported by the transport stage 2 with almost no slip. From this point in time, the two sensors 3, 4 are monitored. If the difference between the lowest measured speed and the speed of the subsequent transport stage 2 is greater than a defined limit value, an overlap is detected which pulls apart at the transition between the two transport stages 1, 2 due to the speed differences. Monitoring remains active until the last trailing edge has left sensors 3, 4. 2 shows the transition area between the transport stage 2 and the transfer rollers 7, 8 of the subsequent transport route (both form a third transport stage).
- the flat mail items 5, 6 are held in a slip-free manner in the transport route designed as a shroud system and are transported on at a higher speed than transport level 2. Since the relatively large takeover rollers 7, 8 for the secure takeover of the mail items 5, 6 are arranged as close as possible to the transport stage 2, there is not enough space to provide the sensors 9, 10 in between. For this reason, the sensors 9, 10 are located in the area of the transport stage 2 at a distance d smaller than the shortest mail items 5, 6 to be processed from the nip points of the transfer rollers 7, 8.
- a consignment 5 enters the nip point of the takeover rollers 7, 8, e.g. From this point in time, sensors 9, 10 are monitored using a light barrier. If the difference between the lowest measured speed and the transport speed of the takeover rollers 7,8 is greater than a defined limit value, then an overlap is also detected.
- the monitoring remains active until the rear edge has left the sensors 9, 10.
- the overlap monitoring can be briefly delayed with the aid of a timer.
