Mail center (Deutsche Post AG)

from Wikipedia, the free encyclopedia
Map of the mail centers of the Deutsche Post AG

A letter center (BZ) is a distribution center for letters set up by Deutsche Post AG . It is primarily used to streamline mail delivery. The distribution system processes 65 million letters from 140,000 letter boxes throughout Germany every day .

history

Up until the 1990s there were 1,000 letter processing stations in Germany.

As part of the “Letter 2000” concept, five-digit postcodes were introduced on July 1, 1993 , letter sizes standardized and letter centers set up. The first was put into operation on August 29, 1994 in Straubing (letter center 94), the last on December 4, 1998 in Regensburg (letter center 93). All 83 mail centers had been set up. Today there are 82 mail centers operated by Deutsche Post AG.

On November 28, 2003, the letter center in Wuppertal (letter center 42) was closed after internal disputes between the BZ management and the works council. Since then there are only 82 mail centers left.

Sizing

The letter centers are divided into sizes according to the processing of their daily letters:

  • S with 450,000–750,000 letters
  • M with 750,000–1,500,000 letters
  • L with 1,500,000–2,250,000 letters
  • XL with 2,250,000–3,000,000 letters
  • XXL with 3,000,000–4,500,000 letters
  • IPZ with 3,000,000–5,000,000 letters (International Post Center)

List of mail centers

The following list shows the size when the letter centers were introduced. The largest is in Frankfurt am Main .

Since the 2010s, capacities have been increased with newer distribution machines. For example, the BZ Kempten (Allgäu) rose from S to M.

Technical Equipment

General

  • Partially automated mail folder (TaBo) for manual format separation and manual stamping of large and maxi letters (GMBf) as well as for the automatic separation and alignment of postcards, standard and compact letters (SKBf).
  • Set-up and stamping machines (AM) for recognizing the postage (including checking the authenticity of the stamps), aligning the letters in a uniform position and stamping them with the day stamp .
  • Standard letter sorting system (SSA), for the automatic sorting of SKBf. This system consists of several address reading machines (ALM), video coding machines (VCM), integrated reading and video coding machines (ILVM) and fine sorting machines (FSM).
  • Aisle sequence sorting machines (GFSM) for sorting SKBf into aisle sequence .
  • Large letter sorting system (GSA) for the automatic sorting of large letters.
  • Image Management Module (IMM) is a computer system for additional processing of the images generated by ALM, VCM, ILVM and GSA. On the one hand, this system increases the reading rate, in that the addresses not read by the machine's own reading computers ( OCR ) are fed to further reading computers (secondary readers). If these secondary readers also do not achieve a result, the images are displayed on monitors at the so-called video coding stations and the postcode is entered manually. This system is also used to determine further information such as the recognition of letters to be forwarded and the checking of special types of postage such as the Internet stamp .

The following is also available in large mail centers:

  • Conveyor and distribution system with unloading device (EV), conveyor system (Föa) and order picking system (KoA) for transporting the letter containers from the hall gates to the individual processing areas and back.
  • Maxi letter sorting system (MSA).

Technical modernization

  • After extensive tests in BZ 04 Leipzig, the replacement of the previous SSA machines ALM, VCM, ILVM and FSM with a new generation of ILVM, which is characterized by higher throughput, higher reading rate and less mechanical stress on the letters, began in 2009. The machine has 128 sorting compartments (“old” ILVM a maximum of 24 compartments), a subsequent mechanical fine sorting (FSM) is therefore no longer necessary. Aisle sequence sorting is also possible with this machine .
  • At the end of 2009, the replacement of the large letter sorting systems began with a new generation of machines that can sort larger mailing formats and enable delivery route sorting.

Exemplary equipment of the BZ Erfurt

The BZ Erfurt was put into operation in October 1996. The supply area of ​​routing region 99 is around 6,400 square kilometers with around 507,000 households. The maximum number of letters per day is 2.2 million. The following technical equipment is available:

  • two integrated reading and video coding machines (ILVM) with four video coding stations
  • three fine sorting machines (FSM)
  • two large letter sorting systems (GSA)
  • two erecting and stamping machines (AM)
  • eight aisle sequencing machines (GFSM)

After the above-mentioned modernization, the equipment in BZ 99 Erfurt looks as follows:

  • a partially automated mail folder (TABO)
  • three integrated reading and video coding machines (IRVneu)
  • a residual hand sorting roller conveyor (RHS)
  • a large letter sorting system (GSAnew)
  • a set-up and stamping machine (AM)
  • eight aisle sequencing machines (GFSM)

Shift work

  • Late shift - mail center dispatch processing (BZA): Monday to Friday in the afternoon to evening hours (in some mail centers -  Sunday BZ  - also on Sunday afternoon), the letters posted within the routing region (from mailbox emptying, post offices and agencies as well as from major customers ) sorted into routing regions.
  • Night shift - letter center inbound processing (BZE): Mondays to Saturdays in the night to early morning hours, the letters that are delivered by the other letter centers or that come from the own BZ for their own routing region are allocated to delivery district groups (= postcodes) Delivery districts or even sorted in order of delivery.
  • Day shift: Mondays to Saturdays during the day, items with a longer delivery time (books and merchandise items, press mail, dialogue mail) are sorted in a similar way to BZE.

The letter centers are therefore in operation almost around the clock.

Oddities

  • The Wiesbaden mail center (65) is located in the Mainz-Kastel district . Mainz-Kastel (zip code 55252) is supplied by mail via the Mainz letter center 55 in Mainz-Hechtsheim , so the mail for Mainz-Kastel is not sorted in its “own” BZ. In order not to have to take a detour to receive the mail sent to BZ 65, BZ 65 has its own (key account) zip code with 65212.
  • The situation is similar with BZ 10 ( Berlin -Zentrum), which is located in a part of Berlin that belongs to routing region 12.
