Definitions
- the invention relates to a method and a device for correcting the gaps between programs according to the preambles of claims 1 and 3.
- the mail items often go through several processing machines, in particular sorting machines, which are connected to one another by means of transport. It often happens that the upstream machines have a higher throughput than the following ones.
- an upstream device for address reading has a higher throughput with 4m / s processing speed with an average mailing length of 200 mm and an average gap of 106 mm than a subsequent fine distribution mechanism with a processing speed of 3.2 m / s with a necessary gap of 70 mm, the gap had to be corrected for the fine distribution machine, since after the speed jump there are only gaps of 45 mm on average. So there is an average of 25 mm missing per gap. In order to create the necessary gaps, the items have to be moved backwards. In existing correction devices, this is done by braking and speeding up the mail items by means of controlled driven roller pairs.
- the first shipment In order to achieve a gap of 70 mm, the first shipment must be moved back by 25 mm. A gap of only 20 mm has been created behind this broadcast. The second shipment must then be moved 50 mm to the rear. If there is another gap, the second would be pushed onto the third program. In order to avoid this, there should be a large gap in all 3 items, ie a missing item in the item stream. However, this would greatly reduce throughput.
- the invention is therefore based on the object of increasing gaps in a mail flow that are too small so that as few mail items as possible have to be removed from the supplied mail stream.
- FIG. 1 shows a schematic representation of the correction device
- FIG. 2 shows schematically the sequence of the gap enlargement from a stream of mail items that have been removed
- the means of transport 3, 4 which feed the mail gap correction units 5, 6 and transport them away from them are designed as cover band systems (FIG. 1). Such one
- the shroud system consists of two belts running in parallel, which are guided over transport and drive rollers. The shipments are clamped and transported between the belts. The mail items arriving via a supplying cover band system 1 are divided over a switch 2 with a controlled, movable distribution element onto the two gap correction units 5, 6.
- the two partial mail streams transported via the transport means 3, 4 are combined in a combining device 7. Subsequently, the mail items are transported onwards by a discharging cover belt system 8.
- the gap correction units 5, 6 each have a controlled, driven cover band system in which the mail items are braked and accelerated again. The ejection of individual mail items necessary for the process takes place in an upstream stage and not shown in FIG. 1.
- the gap correction units 5, 6 and the switches for branching 2 and discharging the mail items are controlled by a control device (not shown), the position of the mail items using sensors, e.g. Photoelectric barriers are determined at any time with a known transport speed.
- the mail flow is divided into two partial mail streams by alternately feeding the mail items to the two gap correction units 5, 6, i.e. the mailings with the numbers 1, 3, 5 (ie the sixth, the fourth and the second mailing before the ejected mail No. 7 m letter run) arrive at a gap correction unit 5 and the mailings No. 2, 4 and 6 (ie the fifth , the third and the first mail before the ejected mail No. 7 in letter direction) to the other 6.
- the length of the arrows indicates the length of the necessary postponement of the respective mail.
- the foremost broadcast No. 1 is not shifted in its relative position.
- the program No. 2 in the other path is postponed by the difference between the minimum and actual luck. In the path of broadcast 1 is broadcast No.
- the division of the mail flow and thus the large gaps between the mail items prevent them from being pushed over one another.
- the mail stream After the partial mail streams have been merged, the mail stream has the same minimum gaps between the mail items.
