Abstract

Sorting systems for the automatic sorting of mail items according to the delivery route sequence in which the number of end points is greater than the total number of sorting systems, characterized in that - the distribution to the available end points is determined by the delivery route and is made up of the delivery person's partial route sequences - the mail pieces are exchanged between the sorting systems and the partial aisle sequences of the deliverers are finished sorting from one end point of the first sorting run before the next end point is finished sorting, - the finished sorting and the delivery of the partial aisle sequences take place at least partially in parallel.

Description

The present invention relates to existing sorting systems in which the sequence of delivery of the deliverer can be automatically provided in the postal delivery by another sorting run.

State of the art

The sorting centers are spread over the country and are to enable a customer-oriented and economic distribution of postal goods to the delivery points (also transition points). Due to different quantity distributions of, for example, standard letters and large letters and different throughputs of the sorting systems, the equipment of the sorting centers is different.

Since the mail volumes are also subject to fluctuations over the year and can double, for example at Christmas time, this must be taken into account when sizing the sorting capacity.

In the past, large letters were sorted by sorting them at sorting centers, transporting them between the sorting centers and sorting them to the delivery offices. There, the large letters were sorted by the deliverers by hand on the gear sequence.

For standard letters, the sequence was produced by special sequencers through several internal runs. These were in delivery offices and were only a few hours a day in use.

With large letters, it makes sense to carry out the sequence of gears already in the sorting center by appropriate dimensioning of the sorting system in order to relieve the deliverers, who can then serve a larger number of transition points. Another aspect is the operating time of the sorting system.

In the past, the mission was limited mainly to the evening time and night time. It is advantageous if the sorting plants can be used more hours of operation per day and these hours of operation can occur in the evening and morning time.

By increasing the number of operating hours per day, the need for sorting systems or their equipment with input points that influence the throughput per hour can be optimized.

Object of the invention

• 1. Minimierung der Sortierläufe
• 2 Die Einsatzzeit der Sortieranlagen von der Nachtzeit weitgehend in die Vormittagszeit verlegt werden kann und damit die Einsatzzeit pro Tag erhöht wird.
• 3. Die zeitliche Abhängigkeit der Eingabestellen voneinander beim letzten Sortierlauf aufzuheben und dadurch gleiche Leistungswerte wie in den vorhergehenden Sortierläufen zu erreichen.
• 4. Die Durchnummerierung der Behälter je Zusteller gangfolgerichtig zu ermöglichen

Sorting systems for automatic sequence sorting with

• 1. Minimization of sorting runs
• 2 The operating time of the sorting systems can be largely shifted from the nighttime into the morning time and thus the operating time per day is increased.
• 3. The temporal dependency of the input points on each other during the last sorting run and thereby to achieve the same performance values as in the previous sorting runs.
• 4. To enable the numbering of the containers per deliverer according to the sequence

description

For example, if there are one hundred sorting machines with three hundred terminals each, an average of three terminals for each sorting system can be reserved for further processing in the first sorting run.

The distribution of the mail pieces on the terminals is not arbitrary but is determined by the sequence. For the allocation to the reserved terminals, the course sequences of the deliverers are divided into partial sequence sequences. The sequence success points obtained from a combination of postal code and street name must also be used for the house numbers in the event that several partial sequence sequences are required for a street.

Thus, the first part of the Teilgangfolgen the deliverer for the sorting system are stored in the first terminal. The same procedure is followed at the following terminals. All terminals reserved for a sorting plant give the sequence of the sorting system.

If a parallel operation is also to be possible, from sorting to sequence sequence points and delivery of the mailpieces by the deliverer, subcontracting sequences of the deliverers must be stored in the terminal stations, which are then also available for delivery with a time delay. For this purpose it is necessary that the finished sorting (eg the second and third sorting pass) of the first terminus of a sorting system from the first sorting pass is completed before the next terminus is processed ( 4 ).

Since not all sorting systems are evenly loaded with delivery points nationwide, a less busy sorting system can relinquish terminals to more heavily used installations ( 1a to 1c ).

By the terminals is specified in which sorting center on which sorting system Subsequences are processed in a temporal sequence.

A special case of the postal items is the Infopost. These are mail pieces with the same content, where the label is created by software and glued or printed directly. The software makes it possible to label the labels and to produce partial stacks whose address range matches the partial sequences of the sorting systems.

The thus prepared Infopost can be supplied with the sorting result from the first sorting run, before the second sorting pass. If the chronological processing of Infopost is not possible, Infopost must also go through a first sorting run.

Another special case are major customers. If unnecessary endpoints are available during the second sorting run, these endpoints can be reserved for customers who receive mail in several containers. Their sorting is completed after the second sorting run.

The second sorting pass, after nationwide exchange of the mailpieces, sorts the mail pieces into containers according to the order of entry for the intended entry point.

Since the sorting systems now have several input points and all input points have access to all sequence sequence points, incorrect sorting can occur during container changes. This dependence of the input points can lead to a reduction in throughput to half.

This can be remedied by dividing the sequence areas, whereby each input location is responsible for one area only. With this principle, the same throughput values are achieved as with the first sorting run. Better staffing and shorter machine running time is the result.

However, the independent operation of the entry points reduces the number of transition points ( 2a to 2c ). By sorting in the first sorting pass through several terminals, this disadvantage can be eliminated.

For the deliverer, it is helpful if its containers are provided with a sequential number according to the sequence. Only when changing the container can the container number be assigned. In order to achieve a clear sequence, parts of a feed sequence of a deliverer may not be processed simultaneously to several terminals. Taking into account this condition, however, several terminals lead to partially filled containers ( 3 ).

It is also useful to provide reserves for the sequence areas of the entry points which facilitate the subsequent insertion of transition points.

1a to 1d show the maximum size of the possible travel sequence points as a function of the number of terminals in the first sorting pass and the number of sorting stations in the sorting center. It should be noted that in the last sorting run for multiple entries and when changing to the next terminal from the penultimate sorting run, all mail pieces of the last terminal are processed.

2 to 2c show the maximum of the possible travel points depending on the number of entry points to which an independent area in the sequence area is assigned.

3 shows a part of a sequence area in the last sorting pass and how the mail pieces of the individual deliverer are stored in the partial sequence. Several subsequences result in the sequence of a deliverer. The illustrated uninterrupted storage in successive containers can be achieved by removing the voids such. B in DE 10 2004 035 365 A1 described by Deutsche Post.

4 shows a possible timing such as sequence sorting and mail distribution by deliverers can be done partially simultaneously and sorting time can be moved from the night to the morning time.
