Definitions

  • the invention relates to a consignment sorting system with at least three modules for processing consignments to be sorted and a transport line for transporting the consignments in a first transport path from the first, the second and the third module.
  • a consignment sorting system of the type mentioned above which according to the invention has a bypass for transporting items to be sorted in a second transport path from the first to the third module, bypassing the second module.
  • a bypass for transporting items to be sorted in a second transport path from the first to the third module, bypassing the second module.
  • the invention is based on the further idea that different sorting processes can be carried out in separate runs on a consignment sorting system. For example, a facility will be used to read addresses and encode the mailings in a first pass for reading, encoding and presorting into collection bins, and in a second pass will use them as a fine sorting machine which re-sorts the coded and presorted mailings into bins , but according to finer criteria.
  • the modules for reading and coding can be bypassed in the second pass through the bypass, whereby the programs are spared.
  • the consignment sorting installation can be a mail sorting installation, in particular a letter sorting installation.
  • a module can be understood to mean a means of modifying the shipment, for example in its position-apart from a pure, targeted transport-or in its components, e.g. by imprinting.
  • a module may include means for positive or negative acceleration, sorting, aligning, inverting, printing, pasting, delaying - e.g. a waiting line, singulating, collecting or the like, and may be, in particular, a means that takes up more of the shipments than a spatially targeted transport.
  • the transport line includes the bypass, which bypasses a transport sub-strand of the transport strand.
  • the bypass itself comprises a transport sub-string, which is expediently shorter than the bypassed by the bypass conveyor section.
  • the bypass is advantageously free of a module which is the same as the second module or analogous thereto.
  • the consignment sorting system is also understood to mean processing the consignments in the form of sorting preparation, for example by applying a sorting code, such as an identity code, a destination code or the like.
  • a sorting code such as an identity code, a destination code or the like.
  • a division of the shipments in at least two containers is understood as sorting.
  • the consignment sorting system comprises a control unit for activating the bypass and steering the consignments through the bypass. In this way, a decision as to whether a shipment stream should run through the bypass, automated and in particular linked with backup functions.
  • the consignment sorting system comprises a control unit which allows a line of a transmission stream from a plurality of directly successively arranged programs in the bypass and a line of only individual broadcasts from the transmission stream in the bypass - wherein other broadcasts of the transmission current at the bypass passed by - locks. In this way, a collision of shipments behind the bypass can be easily avoided.
  • the consignment sorting system includes a control unit for controlling various plant operating modes and activating the bypass depending on the plant operating mode.
  • the consignment sorting system is easy to operate without shipments flowing past the bypass as well as past it. The consignments can therefore not collide behind the bypass.
  • Shipments may be routed past the bypass by the control unit in one plant operating mode and bypassed in the other plant operating mode.
  • a change between the operating modes is expediently only controlled if both the bypass and the bypassed by him transport sub-string is free of shipments, especially only when resting the transport strand or before or after a transport of shipments through the transport strand.
  • the consignment sorting system comprises a control unit for setting a distance between the items in the transport line in response to activation of the bypass.
  • a distance between the programs can be set small when the bypass is activated and thus a high shipment throughput can be achieved by the consignment sorting system.
  • This refinement is based on the idea that, due to the avoidance of the second module and the lower load which can be achieved during transport, a smaller displacement of the transmissions occurs relative to one another. Due to the smaller displacement, the distances of the items to each other, e.g. when feeding into the transport line, be reduced. The distance is thus smaller when the bypass is activated than when the bypass is deactivated. By reducing the distances an increase in throughput of shipments through the consignment sorting system can be achieved at the same transport speed. The adjustment of the distance is expediently in a the shipments singulating feeder the consignment sorting system.
  • the consignment sorting system comprises a control unit for deactivating a bypassed by bypass bypass section in response to activation of the bypass.
  • the wear of the disconnected transport sub-string can be kept low and an emission of noise can be reduced.
  • the consignment sorting system requires less energy when the transport sub-line is deactivated.
  • a simple deactivation of the transport sub-string can be achieved if the consignment sorting system comprises two independently operable drives for driving the transport strand, wherein the control unit is provided for deactivating the bypassed by the bypass conveyor sub-strand by deactivating one of the drives.
  • bypassed by the bypass second module can be turned off when activated bypass, whereby wear and energy consumption of the second module can be reduced.
  • the modules of the consignment sorting system can have different functions.
  • the first module may be a feeder for separating the mailpieces and feeding them to the transport line
  • the second module a printer for printing an identity code or destination code on the mailings
  • the third module a partitioning device for dividing the mailings into different collecting containers.
  • the maximum speed with which the items can be transported through the system can be determined by the second module, for example the printer, which determines the speed limit of the transport by its printing speed. If the second module bypasses the bypass, it may happen that this upper speed limit is no longer relevant, but another module sets a higher speed limit so that the speed of the shipments can be increased by the system.
  • the item sorting system advantageously comprises a control unit for setting a transport speed of the items in the transport line as a function of an activation of the bypass.
  • a maximum transport speed can be set automatically and an optimum throughput of the system can be achieved.
  • Illustrations of handwritten addresses are usually issued online to an employee who reads the address and enters it into a computer so that the appropriate mail can be encoded according to the input.
  • a small amount of time is required in which the item is transported in a transport path for generating a time delay between the reading module and the coding module.
  • Such a transport route may have a length of 40 m and more and a plurality of curves.
  • the second module is a transport path for generating a time delay, by bypassing this module, a considerable protection of the shipments can be achieved.
  • the editing function of the module the time delay and expediently not primarily a transport to a destination, since the transport route is particularly longer than a technically meaningful transport path between modules that it connects.
  • the transport path can be one or more parts, so be interrupted by other modules.
  • a second module which has an alignment means for aligning the items in a common orientation, can advantageously be bypassed by the bypass.
  • the second module has a labeling means for labeling the programs.
  • This module can be conveniently bypassed in a second pass where no coding needs to be done.
  • the labeling means may include a token cancellation or an identification printer, e.g. a barcode printer, its.
  • the second module has recording means for recording an image of the programs, then this can advantageously be bypassed by the bypass in a second pass in which addresses are already present in machine-readable form.
  • the consignment sorting system advantageously comprises a control unit for controlling at least two different sorting methods and for activating the bypass as a function of the sorting method to be carried out.
  • the sorting method for example, first the sorting method of reading the addresses and coding and then the sorting method of a fine sorting, one or more bypasses can be simple, in particular automatically, be activated and the shipments are thus spared.
  • the consignment sorting advantageously comprises a control unit that blocks switching from the first to the second transport when there are shipments in a bypassed by the bypass section of transport. For example, switching between the transport routes may only be permitted at the beginning of a sorting process, or switching may only take place after a waiting time that is so long that all shipments have been transported out of the transport sub-line to be bypassed during this time.
  • the FIGURE shows a schematic representation of a consignment sorting system 2 with a number of modules 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 for processing consignments 24 to be sorted on a transport line 26 for transporting the consignments 24
  • the module 4 is a pre-sorting device into which the mailings 24 are inserted in a sacked manner and which sifts out oversized, too small, too thick or inflexible mailings 24 and allows only standard letters to pass. These are brought to the module 6, which includes a separating device, also called Feeder, which separates the items 26 and sets a predetermined distance from a control unit 28 between them.
  • the control unit 28 is connected to all modules 4, 6, 8, 10, 12, 14, 16, 18, 20, 22 and other components of the consignment sorting system 2 control technology.
  • the individualized items are clamped by the transport line 26 between two elastic bands and the module 10th transported, which is designed as alignment and aligns the items 24 in passing at its lower edge. Without interruption, the mail items 24 are then guided by the transport line 26 past a reading device 30, for example a bar code reader and address reading device, which reads an optionally present on programs 24 barcode or on the mailings 24 printed address. Since the programs coming from the module 6 24 usually carry no barcode and some programs 24 have handwritten addresses that can not be detected by the reader 30, the programs 24 are guided by the transport line 26 to an image pickup device 32, from both sides of the Programs 24 recordings in a bitmap format and the control unit 28 feeds.
  • a reading device 30 for example a bar code reader and address reading device, which reads an optionally present on programs 24 barcode or on the mailings 24 printed address. Since the programs coming from the module 6 24 usually carry no barcode and some programs 24 have handwritten addresses that can not be detected by the reader 30, the programs 24 are guided by the transport line 26 to an image pickup device 32
  • the control unit 28 sends images of those broadcasts 24 whose address is not machine-readable online to an unillustrated reading center in which the images are displayed on screens and read by personnel who input at least parts of the address via a keyboard. This data is passed on to the control unit 28 online.
  • the mail items 24 are fed to the module 12 which is designed as an alignment means, which brings the mail items 24 into a uniform orientation, for example such that the address of all the mail items 24 is upside down and the stamp is aligned in the transport direction.
  • the authenticity of the stamp is then checked and the stamp is canceled.
  • the mail items 24 are conveyed from the transport line 26 to the module 22, which is a divider, and roughly distributes the mail items 24 into a plurality of containers according to their address, for example, 100 postal codes per container.
  • Conceivable as a module 22 for processing the consignments 24 is also a distribution device in only two collection points or a shipment collection means for feeding to a further sorting.
  • It consignment sorting system 2 also includes with the module 8, a second feeder for separating consignments 24, which are already prepared by companies delivered. These items are already aligned uniformly and provided with a promotion fee stamp, so that they no longer require editing by the modules 12 and 14.
  • the mail sorting system 2 can be fed by the module 8, in which the control unit 28 activates a corresponding switch 34, which leads the mailings 24 into a bypass 36 and thus past the modules 12 and 14.
  • the bypass 36 comprises a transport sub-strand 38, which is driven by its own drive 40, so that the control unit 28 can set the transport sub-strand 38 in an activation of the bypass 36 in motion and bring in a deactivation of the bypass 36 to rest.
  • a transport sub-strand 42 which supplies the modules 12, 14, associated with its own drive 44, which - depending on the state of the bypass 36 - can be turned on or off.
  • the activation of the bypass 36 may be effected by the control unit 28 when the consignment sorting system 2 is not fed by the module 6, but solely by the module 8 with corresponding uniformly oriented and depreciated consignments 24.
  • the plant operating mode becomes switched over and the modules 12, 14 and the drive 44 are turned off by the control unit 28.
  • the module 8 automatically loads the mail sorting plant 2 when the module 6 has large loading gaps, for example when the presorting device has run empty.
  • the control unit 28 waits until no more shipments are in the transport sub-strand 42 and then activates the new plant operating mode and thus the module 8 and the bypass 36.
  • the mail sorting system 2 can be used for fine sorting in a further plant operating mode, eg for fine sorting of the mailings 24 pre-sorted in the first pass as described above.
  • the containers filled with mail items 24 are then removed from the module 22 and the consignments 24 contained therein are fed into the feeder of the module 8, which again separates the consignments 24 and feeds them to the transport line 26.
  • These shipments 24 are all uniformly oriented, canceled and provided with a machine-readable address or identity code, which are read by the reader 30.
  • the modules 12, 14, 16, 18 and 20 are not required.
  • a switch 46 is switched by the control unit 28 so that a second bypass 48 is activated, which comprises a transport sub-strand 50. This is driven by a separate drive 52 and can therefore be driven or shut down independently of the other parts of the transport line 26. If the items are guided over the bypass 48 in the transport path at a second pass, the modules 12, 14, 16, 18, 20, the drives 40, 44 and a further drive 54 are switched off, so that the corresponding part of the consignment sorting plant 2 rests and the consignment sorting plant 2 runs quietly and with little wear.
  • a distance between the transmissions 24 in the feeder of the module 8 is set, which is smaller than a distance between transmissions 24, which pass through the modules 16, 18 and 20.
  • the maximum transport speed is determined by the printer of the module 20 during complete operation of the mail sorting system 2. If the modules 18, 20 deactivated with active bypass 48, the control unit 28, the transport speed of the shipments 24 according to other conditions faster, whereby the throughput of the consignment sorting system 2 can be further increased.
