Control for conveyor systems

To control the flow of traffic in conveyor systems, i.e. for Control of the conveying containers from one transmitting station to one Receiving station, basically three different possibilities are known.

The first of these possibilities is so-called target tags to be attached to the conveying containers, through which adjusting devices located in the course of conveying routes accordingly the desired destination can be influenced so that the conveying containers are discharged at the desired receiving point. at It is known, for example, for pneumatic tube systems to have identification marks distributed over the circumference of the pneumatic tube carriers for the purpose of identifying the target to be provided which influence the scanning devices arranged on the actuating devices in such a way that the switching position the adjusting devices in the direction of the desired target station is established or optionally remains.

The license plates can take on a wide variety of forms or * are based on various physical criteria; So there are, for example, contact rings for actuation from contact sensors, but also magnetically, optically or inductively or capacitively acting characteristics are known, all of which are scanned without contact.

A fundamental disadvantage of this described target identification is that »using the target setting devices of license plates or license plate rings, on the one hand, is structurally relatively complicated due to their adjustability and on the other hand due to the mostly in conveyor systems

existing relatively large number of different goals are relatively expensive to build. Because of, this relatively complicated and expensive structure can cause malfunctions due to wear and tear or damage to the target, adjusting devices cannot always be avoided. As special interfering with the possibility of controlling a conveyor system by means of target identification elements arranged on the conveyor containers proves the fact that the conveying containers, which are in a Conveyor system represent the most stressed components, at the same time the most vulnerable elements of the entire system, namely, borrowed the aiming adjusters, wear. Besides, it's considered more economical Nacht.eil to see that in conveyor systems a relatively large number of conveying containers which, due to the target setting devices attached to them, are relatively are expensive, is needed, as possible at each transmitter station conveying tanks must always be available to avoid any To be able to carry out conveying tasks immediately without requesting conveying containers from other stations. In every conveyor system So there are a lot of conveying containers that are not constantly, but only during relatively short intervals within a day.

The second basic system for controlling a conveyor system works with neutral conveyor containers, i.e. with containers without Identification elements, in order to avoid the described main parts that occur when attaching identification elements to the conveying containers, to avoid. ·

With this type of control, the target identifier communicated to a system control when the conveying container is given up to When the conveying container arrives at the destination station, this must remain precisely assigned, essentially to the circuitry Keep effort within limits, set up conveyor systems in which only a single conveyor container can move "

But there is also already a pneumatic tube system known that under Providing a correspondingly greater circuit complexity monitors and controls individual conveyor line branches in such a way that the Sequence of several pneumatic tube carriers moving in them the sequence of the destinations stored in a central switching device corresponds to the same. This monitoring is made easier with this pneumatic tube system because it is a pneumatic tube system with a central multiple switch acts, which - as known in such a way is operated that the receiving stations and transmitting stations of the system are connected to separate transmitting and receiving lines and that all transmission lines on the one hand and receiving lines on the other hand via the central multiple switch with each other are connectable. All pneumatic tube carriers must therefore on their way from a sending station to any receiving station pass through the central multiple switch. Monitoring and control the transmission lines are therefore carried out in principle in such a way that the sequence of the pneumatic tube carriers arriving at the central multiple switch in the order in which they are stored in the central switching device Objectives of the pneumatic tube carriers.

These control and monitoring functions are carried out by a so-called Executed departure regulation, which prevents a rifle from being smuggled into a transmission line at a transmitting station is when this transmitting station is between a straight in the driving tube located pneumatic tube and the central multiple switch is located. The departure regulation is essentially implemented by that each transmission path is divided into several zones, and that those within these zones are connected to the transmission lines Transmitting stations are controlled in such a way that the cans only then go off into the transmission line if there is no further bushing on their way to the central multiple switch within the corresponding zone is promoted. For this purpose, the switching device assigned to the central multiple switch contains a so-called switch Retrieval circuit that - controlled by the individual Zone contacts delimiting zones - the individual bushes cyclically from their transmitting stations.

VPA 9/420/5388 -4-

109852/0787

It is obvious that the departure regulation is essential for the fault-free functioning of the entire system is, there is a restriction in the traffic performance of the entire system. The 'well-known' one who works with neutral pneumatic tube The system enables an increasing traffic flow of the system with ever finer division of the transmission lines into zones at the same time, however, a constantly growing amount of circuitry, so that the zone division cannot be arbitrarily small, i.e. certain restrictions on the traffic performance of the plant can be accepted must be taken.

Overall, it can be stated that the known systems, when using identification elements on the conveyor containers, have the disadvantage that the most heavily stressed elements of the system have the most sensitive mechanical structure when expensive stocks are kept ₉ only relatively eeliXeetit & usg @ & u $ stsn <, Förd @ rb @ faältam ' ₉ and ■ that this disadvantage © öu ^ öh eil® "btkiimtea Aäiagaa, _{9 use} di @ neutral cans ^ swar Yeraieiss w @ s?

Identify the identity code and the central switching devices influence in such a way that these after interrogation of the memory address corresponding to a scanned identity identifier control the corresponding points and receiving devices using the destination information stored there.

The advantages of this conveyor system can be seen in the fact that any traffic restriction within the transmission lines is avoided, that the monitoring of the transmission lines by means of a departure control is no longer necessary and that the conveying containers are still with simply constructed, non-adjustable oak elements can be provided so that no malfunctions due to damage or wear and tear occur to a large extent can. ·

It goes without saying that a conveying container which bears such fixed identity marks is more expensive to manufacture than a completely neutral conveying container, ie a conveying container without any identification, but the additional costs are higher than the additional costs of iron conveying containers with adjustable aim indicator is not -allzu gT-e.Ti & rend and w @ rdsn .zusätzlich by the non mehr.notwendige monitoring ä @ r Soadestränge means Abfahzfceregelung compensated ·

So from ezncv control for conveyor systems with control devices that are located in the course of conveyor lines and that act on conveyor containers.

The term control devices is used in this context in to be understood in the most general form; under the term of the control devices can switch devices, station devices, Register or storage devices as well as drive and monitoring devices fall.

The object of the invention is to provide a To create a control concept that can be used for all plant structures and all basic control systems and that thus enables an essentially modular structure of the control. This object is achieved according to the invention resolved that the actuating devices were strictly limited to them, individual peripheral tax rates · are assigned to the one hand linked with control elements that are hierarchically subordinate inside, preferably integrated into the control devices and, on the other hand, in this way via control lines standardized with regard to the incentive and target criteria of the actuating devices are connected to a program control unit that is hierarchically superior to them with regard to the extent of logical links, that the incentive and target criteria caused by the control elements on the control devices on the part of the corresponding peripheral tax rates of the program control unit for calculation the branches of the conveying route to be provided for the conveying containers between the sending location determined from an incentive criterion and the receiving location determined from a target criterion and to check the traffic status of the conveyor system, in particular within the calculated branches of the conveyor route, and the The switching and control criteria obtained from this calculation and testing of the peripheral tax rates, which in the course of this Conveyor route branches are assigned to lying control devices, are transmitted.

The individual peripheral tax rates therefore contain the Control for the individual functions to be carried out by the actuating device assigned to them; so every tax rate contains the decentralized control logic for solving a limited problem. Examples of such limited problems are for example Pneumatic tube stations5 which can be used as send, receive or through stations and their respective position of the target-j switching and control criteria within depends on the system »

The setting elements connected to the individual peripheral control sets are to be understood as meaning those devices which can be directly influenced either by the conveying containers, by conveying means or by operators. Examples of such actuating elements are therefore tube contacts, flow contacts or mechanical ¥ älileinriclitungen ₀

All actuator individual peripheral control sets are connected via a view to target Anreis- _9, switching and control criteria normalized control lines to the program control unit. In this case, these normalized control lines are to be subdivided into two main groups, the, transmitted one as the active, which is to be considered other than the passive group \ be the first group while incentives messages via the switching state and target information of the corresponding actuating devices to the program control unit, while the second group essentially transmits start signals which, within the control logic of the peripheral control sets, lead to the switching or reversal of corresponding control elements of the control devices assigned to them »

The main advantage of this principle is the individual control unit peripheral tax rates and normalized control lines is that certain types of peripheral Tax rates always contain the same logical outputs; such groups are, for example, station facilities,

VPA 9 / 61Ö / O1O3

VPA 9/420/5388 -9-

109852/0757

Switch devices or drive devices assigned. Each structural unit comprising a peripheral control set can be designed in such a way that it is suitable for solving the logical problems of the most extensive control device in each case. Peripheral tax records of this group, which have a simpler structure, then only contain fewer logical outputs; there are therefore fewer logical outputs. As an example of this, pneumatic tube stations may serve, which on the one hand work with a keyboard for the transmission of destination identifiers and on the other hand without the keyboard. for processing pneumatic tube carriers with target identification. In the case of the latter peripheral tax rates, the standardized control lines required for the transmission of the target information are then omitted.

The same individual items of information or groups of information are always present on the standardized control lines, see above that the structure of the central program control unit is independent of the design of the system, in the case of a pneumatic tube system e.g. regardless of the nominal diameter of the pneumatic tube or the type of discharge of the pneumatic tube cans at receiving stations, is.

On the other hand, with regard to the peripheral tax rates, it is completely irrelevant whether the actuating devices assigned to them within branched systems, from systems with central ones Distribution devices or used by ring-shaped systems are, so that the structure of the transport network is only for the Program control unit is of influence.

According to an advantageous development of the invention, each peripheral tax rate is above the incentive criterion of the relevant Control device leading standardized line connected to an interrogation device, which in the presence of an incentive criterion polls the peripheral tax rates cyclically. The interrogator, which is preferably constructed as a chain circuit

integrated directly into the program control unit. The peripheral Tax rates can be structured to have different ranks with respect to the interrogator's access to the. have respective incentive lines. For example, a higher rank is -justified for conveyor systems with a central distribution device, in which, in general, it is precisely this central distribution device that has a certain bottleneck within the overall system Requirements on the part of these central distribution facilities are therefore preferred. However, it is also possible that a peripheral tax rate, which is an incentive criterion to the program control unit to indicate that, for example, at a transmitting station, a conveying container in the Conveyor system is to be introduced, due to the occupancy of at least part of the conveyor path to the receiving station no switching criterion that triggers the smuggling of the conveying container receives, but the rank of its incentive line is initially increased to this incentive not only again after a whole. Pass through the interrogator, rather if necessary, to be cleared in between after the occupied conveyor line is clear.

A further advantageous development of the invention provides that the peripheral tax rates have individual connection devices ₉ which, after receiving an acknowledgment code from the interrogation device, connect the respective peripheral tax rate to the standardized control lines. The standardized control lines "do not need to be assigned to each peripheral control record in large numbers, but can be routed into the program control unit in the form of a bundle of wires, with the inputs and outputs of the corresponding peripheral control records being connected to the standardized control lines via a coupling network.

The incentive line therefore decreases as a result of its direct connection to the program control unit or to the

VPA 9/610/0103

VPA 9/420/5388 10985270757 " ^1X "

he.it integrated interrogation device a special position within of the standardized lines. It is particularly expedient to use the incentive lines after transmission of the incentive criteria to the interrogator from the interrogator or the outgoing reverse signal is transmitted to the program control unit in the form of an acknowledgment identifier, which is used to connect the corresponding peripheral control rate to the standardized control lines leading into the program control unit.

According to an advantageous embodiment of the invention, the program control unit contains, as the actual core piece, a traffic program memory which is based on the system-specific traffic structure the conveyor system is coordinated. This traffic program memory can be viewed as a circuit analogue, for example to the actual conveyor system. In the case of a branched system, this would mean, for example, that the individual Route branches are assigned corresponding lines and that the branch points are simulated by contact devices are. However, the traffic program memory can also be implemented, for example, by means of a switching matrix, the intermediate paths in the switching matrix being selected so that only those in the system occurring connection paths within the switching matrix occur in terms of circuitry. For checking the idle or busy status the entire system or partial sections of the system are then possible processes as they are in telephone technology are common in centrally controlled switching systems. As a particularly advantageous form of implementation of such However, the traffic program memory proves to be a digitally encrypted form of the system display, since in this way the testing, querying and control, as well as the input and output of route-defining information is simplified.

The use of a circuit analog of a conveyor system to control the same is already known, however

VPA 9 / 61O / O1Ü5

VPA 9/420/5388 _ ₁₂ -

109852/0757

these analogs, which are also referred to as commands pe icher ■, not with the within the scope of the control according to the invention _; used 'traffic program memory are compared. _,

The known command memory is namely a device in which when a conveying container is introduced into the conveying system, the corresponding target information is sent to a the location of the command memory assigned to the task location and then changes its storage location with the movement of the conveying container within the command memory. In a command memory of this type, the traffic structure of a conveyor system is not directly represented by a corresponding one analog or digitally encrypted circuit implementation shown, but only the sequence of is shown by constant cyclical switching of the target information Retain the conveying containers or their destinations unchanged.

Corresponding to this circuit implementation of the command memory and its mode of operation, it is only known so far, such analogs for the control of circulation-operated Use conveyor systems, as such in branched systems Control method is not readily applicable.

It is also already known to control circuit-operated Systems practically provide a reversal of the principle just described, which manifests itself in the fact that the specific Targets assigned to conveying containers on a fixed storage location, which is the input location or the destination of the conveying container corresponds to, are stored and that then information relating to the ring-shaped arrangement of several output points correspond one after the other, passed by the conveying container-specific identification information or with this be compared. This system can, for example, be controlled in such a way that at each memory location the identifier of a target station of a conveying container, all identifiers of the receiving stations of the conveying system are moved past and at

Correspondence between the stored identifier and the one compared with it Identification of the destination an output command is given. This principle of the structure of a command memory is also completely different from that in the control according to the invention used traffic program memory, since the latter for Calculation of a free path between a transmitting station and a receiving station or to output corresponding route data to a setting device, while with the known, Command storage the path of the conveying container within the conveying systems is predetermined by the ring-shaped structure of the same. .

The traffic program memory used in the controller according to the invention can advantageously be connected to an intermediate memory which stores all route data determined in the traffic program memory for a conveying route between the actuating device causing an incentive criterion and the second predetermined by the system structure or the target information Receives adjusting device. In the case of a pneumatic tube system with a central multiple port, the buffer would accordingly the route data for the route between a transmitting station and the one generally upstream of a central multiple woe Storage line.

An advantageous embodiment of the program control unit is that it is assigned a testing and setting device which is the peripheral tax rates of the conveyor route determined by means of the traffic program memory lying control devices with regard to their switching and occupied status checks and adjusts according to the determined route data, unless this is due to a pumping process currently in progress, which at least partially contains the same conveying path is prevented. Appropriately, this test and setting via the standardized control lines of the peripheral Tax rates made by the testing and adjustment facility

the corresponding peripheral tax rates using the "■" controls the questioning device individually. Within conveyor systems that receive funds with the target indicator "contain," ■■ the determination of the route data follows expediently so that the traffic program memory on the one hand via the interrogation device an identifier signal representing the location of the peripheral tax rate providing a sending incentive, and on the other hand via the connection of the corresponding peripheral tax rate to the standardized Control lines the target information is passed '. In cases in which the traffic program memory is designed as a switching network, these two pieces of information can be transferred to the two levels of the switching matrix are fed, after which by a simple known from telephone switching technology ■ - route search a Way is determined.

In systems with a central distribution device, in particular in pneumatic tube systems with a central multiple switch, a An incentive on the part of a peripheral tax rate assigned to a transmitting station does not necessarily lead to destination information being transmitted to the traffic program memory, because in this type of system the conveying container - in particular the pneumatic tube carrier - is inevitably at a defined point must arrive before the central distribution facility, where then the destination information of the conveying containers sent by them for all the transmission stations located along the same transmission line can be determined »With this technology, the sequence of the conveying containers arriving at the central distribution device is also important irrelevant, since the goal belonging to each promoter is older is fixed to the conveyor tank itself "

In the case of conveying systems designed for conveying containers with fixed identity marks, when a conveying container at a transmitting station the significance of this identifier

This is advantageous here License plate memory designed as an associative memory; i.e. the storage locations are arranged according to words, which consist of the identity code and the associated target information » If a conveying container, its destination information under the corresponding Identity marking is set in the associative identifier memory to the place of its dispatch When the closest reading device arrives, the peripheral tax rate of this reading device sends an incentive criterion to the interrogation device from which then the standardized control lines of the reading device to one of the associative license plate memory assigned comparator device emits, the other hand the words stored in the memory locations of the associative identifier memory are supplied one after the other, and which, if the identity codes match, the target information transfers the corresponding word to the traffic program memory.

The traffic program memory is in turn received - as with conveyor systems with target label-affixed conveying containers - both information about the location of the stimulus on the part of a conveying container as well as the target information belonging to this conveying container.

In the event that the control of the invention within a Conveyor system that allows transport to be carried out without any destination and identity plates Conveyor container is used, and in'der the

Destination information about dialing devices arranged at transmitting stations the program control unit is used, it also contains an associative identifier memory, however, its storage locations are preferably based on the identifiers of the actuating devices that emit the incentives are ordered.

According to a development of the invention, the program control unit in addition, a counter, its status when entered an identifier in the program control unit is incremented by one counting unit. In this way it is achieved that the order of conveying containers that are posted at the same sending station or the sequence of conveying containers that in storage or register facilities in the course of the driving tube route are located, can be checked, so that an exchange the destinations assigned to the corresponding conveying containers are not possible with each other.

A similar counter is already used in a material flow control for a multi-branched, from several route sections existing conveyor with contactless switches at the beginning and at the end of each route section and with the Section memories assigned to route sections have been used. With this material flow control, the to Control information belonging to the individual conveyed goods in the order of their entry into the route section in corresponding section memory is stored and in the same order when the respective conveyed goods run out the route section is stored again and, if necessary, on the section memory of the next route section transfer.

The target information is also used in this material flow control moved cyclically through a command memory. Included

sets the counter, its individual memory locations each one contact the switch that delimits a section of the route are assigned by a "with each switch actuation by M ' increased significance the addresses of the control information contained in the respective section memory.

While with this material flow control the target information according to addresses that are given by the respective counter reading, is stored in the controller according to the invention proceed for a conveyor system in such a way that the words written into the memory locations of the associative identifier memory sorted by the ID of the sending location and by the respective Counter reading and the one assigned to the transport container Target information can be added. The resulting benefits will be explained later in the explanation of a corresponding one Exemplary embodiment are shown.

The program control unit expediently contains in turn a matching device, which on the one hand on the part of the interrogation device in the presence of an incentive criterion one of the incentive lines that of the corresponding peripheral Tax rate is supplied and on the other hand all im Associative identifier memory stored words are offered cyclically one after the other. The comparator then searches for the memory word that has the lowest count for the identifier being searched for and admits it this identifier and belonging to this lowest counter reading Destination information to the traffic program memory.

For the communication between the comparator device and the associative license plate memory, it has proven to be advantageous to assign a buffer to the comparator device, into which the first one taken from the associative identifier memory Word with the searched identifier is entered and from which this

Pur den Pail, that the word in the cache is " has the higher count, it is deleted and the word just removed from the associative identifier memory is deleted in written into the buffer.

Constructively arise for the implementation of the invention Control several ways. An advantageous possibility is to be seen, for example, that the peripheral Tax rates can be combined individually or in groups in one unit and integrated into a central frame are then expediently at the same time the recording of the program control unit serves. Ea is also possible, however, the peripheral tax rates at the location of the actuating devices assigned to them to attach.

Another advantageous possibility in the constructive implementation of the control according to the invention is to use in to provide a patch panel on the central rack frame, on which the connection of the peripheral control sets with the program control unit he follows. This connection can be done in the simplest form in that the patch panel has sockets, which then according to the structure of the program control unit via plug cords are connectable to each other.

With such a centralized structure of the control system, you can use it prefabricated kits, for example the peripheral ones Tax rates, the traffic program memory, the comparator and the interrogation device can be easily interconnected with one another, whereby due to the clear assignment of the individual kits to each other results in a simple form of wiring.

The number of cans to be stored in the storage sections SSi is determined generally according to what is required of the overall system Traffic performance.

As can be seen from FIG. 1, both fans are G1 and G2, as well as the transmitting and receiving stations S1 to S4 and E1 to E3 in addition to the storage path SS1 and the central one To accept multiple switch ZM as control devices in the sense of the registration. Each of these actuating devices is accordingly linked to a peripheral Steueraatz, the drawn Connections from the actuating devices to the assigned peripheral tax rates, the supply lines of actual actuators, Represent zontakten, dialing devices, etc. Each of the The connections drawn between the actuators and the peripheral tax rates are therefore generally in the form of a bundle of lines to accept.

The peripheral tax rates are related to the system shown to be divided into four groups. The first group is made up of the two tax rates PSg1, assigned to blowers G1 and G2, PSg2 formed, which have practically no logical links, but in principle only contain switching functions. The second group of peripheral tax records is assigned by the sending stations S1 to S4 or the receiving stations Et. To E3 peripheral tax rates PSsI to PSs4. or. PSeI to PSe3 formed, which are essentially the punctures of the mechanical

Control actuators within the stations. For the sake of the fact that the system shown is used to transport pneumatic tube carriers without a destination identifier, the group of peripheral tax records PSs1 to PSs4 could also be a different group than the peripheral tax records PSeI assigned to the receiving stations E1 to E3 due to the target links within the peripheral tax records PSsI to Pss4 belong to PSe3. The third group of peripheral tax records is formed by the peripheral tax records PSssi and PSzm assigned to the storage section SS1 and the central multiple switch ZM.

The standardized control lines assigned to the individual groups, namely NSgI, NSg2 ;. NSsI to NSs4 or NSe1 to NSe ?; NSs s, NSzm, are linked to the program control unit PSE, with the Connections between the program control unit PSE and the peripheral tax records are to be assumed as a trunk group.

ZSP memory which, iev; - :: il.i, receives the route data for a determined route, linked with the Pr ^: li ~ and one sub-device PEE.

The function of the 3t ~ ί ^ ΛΤΗ ¹ : for a conveyor system in which the conveying containers with Zielir-n: -,:: ^ hGn operate, will be explained ^{in the following on the basis of a typical Fo-4uan 1} :

It is assumed that ■ d * -S äor peripheral tax rate PS1 is assigned to a transmitting station L., and due to the presence of a dispatch request, an arrival i ^ v ^; \; l on his incentive line AU leads » As a result, <ii ': A M'r a ^ e facility AE searches for this incentive and identifies the'pi:> ip ^ ersn tax rate PS1.

Setting device PSE passes. The testing and setting device PEE then checks the in the course of the detection signal of the peripheral tax rate PS1 and through the standardized

3teuerleitunken i; Sl determined target information transmitted Conveyor track lying adjusting devices with respect to their Frei- bsw. Busy.

Pur the further processing of the pre-paring within the program control unit there are two cases to be distinguished. In the case, that at least part of the way between the place of sending and the Location of the closest reader for the target number is occupied, the eligibility, i.e. the rank or degree, of the peripheral tax rate PS1 increased, so that the incentive on the incentive line AU is preferred over other incentives is treated.

In the second case that the conveying path described is free, the testing and setting device PEE sets all setting devices on this path in the sense of the target information and transfers the corresponding peripheral tax records Signals that identify the conveying path leading past the assigned actuating devices as occupied. Afterward is a PEE on the part of the testing and setting device Send command passed on to the peripheral control set PS1, which is used to send the conveying container that triggered the incentive or to loosen the infeed of the conveying container "to leads to preventive lock. Then the information in the intermediate storage ZSP and in the testing and setting device PSE deleted so that the program control unit further requirements "is available.

In the figure 3, a program control unit is shown which serves to control a conveyor system in the conveyor container deal with identity tags. If this conveyor system has the same structure as the conveyor system according to FIG it is assumed that the number and location of the peripheral Tax rates PSt to PSn are usually almost the same, single

borrowed the sound reinforcement of the logical outputs of the peripheral tax rates PS1 to PSn differ in the places where information about the identity or the destination of the conveying container are processed.

The structure of the actual program control unit is related to the interrogation device AE and the testing and setting device PEE as well as their correspondence with each other and via the incentive lines AU to AIn on the one hand and the standardized control lines NS1 on the other hand with the peripheral tax records PS1 to PSn the same as for the program control unit according to FIG. 2.

In contrast to the structure of the program control unit according to the figure, however, the traffic program memory VPS does not receive any destination information via the standardized control lines NS 1, _. on the other hand, this continues through the identification of a stimulating peripheral Tax rate obtained identification signal. The target information are therefore not entered into the traffic program memory VPS, but go through the input memory ES, the serves for buffer purposes, in the associative identifier memory AES, in which it is in words, the identity identifier and contain the destination information of each conveying container, are stored sorted by identity code.

The traffic program memory VPS receives the information for each transport container The target information belonging to it is therefore not directly via the standardized control lines NS1, but rather via the comparator device VE, on the one hand via the output memory AS, which, like the input memory ES, is used for buffering purposes, with the associative license plate memory AKS and on the other hand is connected directly to the standardized control lines NSl.

At every setting device where information about the

Identity identifier of the one located at this control device. Conveyor container is present, so this ■ identity identifier is supplied to the comparator device VE via the standardized control lines NS1. At the same time or afterwards the Comparator VE offered all the words stored in the associative identifier memory AKS until the word is present with the identity feature that matches the identity identifier offered via the standardized control lines NS1. The target information belonging to this identifier is thus taken from the associative identifier memory AKS read out and stored in the traffic program memory VPS entered, which thereupon - as already described with regard to the program control unit shown in FIG - Calculates the route data and transfers them to the buffer ZSP, whereupon the latter causes the testing and setting device PBE to contact the on the one hand by the identification signal and on the other hand by the from the associative license plate memory AKS to connect target information obtained to the given route or to the actuating devices located in the course of this route.

The individual control processes within the program control unit should be explained in the following using an example:

It is assumed again that a conveying container on the control device assigned to the peripheral tax rate PS1, so that this peripheral tax rate PSt via the incentive line AU emits an incentive, which then - as already described by the interrogation device AE identified and with a backward indicator is acknowledged via the incentive line AU, whereupon the peripheral tax rate PS1 is sent to the standardized control lines NSl turns on.

A distinction must be made between two cases in the following. In the case, that on the standardized control lines, on which "target information can be present, no signal potential is recognized, takes over first only the comparator device VS via others. the standardized control lines KSl the Identitilts'-iennzeichen of the conveying tank. For the second case that the stimulating control device is an control device with Delivery of target information is, however, at the same time via the corresponding standardized control lines in the input memory ES and in the next step with it also the target information "'itinte" in the associative license plate memory AKS. '. '

In both cases it applies that after the identification code has been accepted by the comparator VE '.', 'Locate the associative identifier memory AKS or from the output memory AS are taken over until the equality of the both the comparator VS offered identity ■ license plate is present. In this case, the comparator device VE transfers the destination information to the traffic program memory VPS, which at this moment, or already before, the identification signal of the peripheral tax rate PS1 received from the interrogator AE. From this identification signal and the destination information the traffic program memory VPS in turn determines the route data, which is then transmitted via the intermediate memory ZSP the testing and setting device ΡΞΕ are handed over to the then checks the route determined by the V. 'data, i.e. to the control devices located in the course of this conveying path or to the peripheral tax rates assigned to these actuating devices.

Again, two different cases are possible. In the event that some of the control devices located in the course of the determined route are occupied , the authorization

i.e. the ranking of the stimulus lines AU of the peripheral PS1 tax rate increased, then it is examined whether it is "In the case of the peripheral tax rate PS1, one with Atgate is about target information, and accordingly, if so is recognized as correct, the target information written in the associative license plate memory AKS is deleted; by doing Case that there is no target information at the peripheral control record PS1 is present, the program control unit triggers and goes to processing a next request within the conveyor system uter.

For the second ^{T; i} all, that is, that the tested conveying path is considered free. is recognized, the testing and setting device PSE sets the setting devices located in the course of this v / eges according to the target information and transmits signals to the corresponding peripheral control records which identify them as occupied. Subsequently, the sending or triggering command for the conveying container pending there is transferred to the peripheral control set PS1 or the actuating device assigned to it.

In the event that the recipient is at the end of the conveying path the destination information is no longer needed, this information becomes in the associative identifier memory AKS, while the destination information is deleted in the event that the recipient receives it for the further control of the conveying container by the conveying system still required, in the associative number plate memory AKS remain, where they turn to the comparator device in the event of a later query VE can be offered. Then the program control unit triggers, i.e. the one in the testing and setting device PSE and the data in the ZSP buffer are deleted again.

Containers, i.e. conveying containers both without a destination label and without an identity label, operate. The individual peripheral Tax rates PS1 to PSn are in turn connected to the interrogation device via the incentive lines AU to A13 AE and linked to the testing and setting device PEE via the standardized control lines NS1. The assignment of the Traffic program memory VPS via the intermediate memory ZSP with the testing and setting device PEE and their linkage with the interrogation device AE corresponds to the corresponding connections or links in the program control unit according to FIG. 3.

In contrast to the program control unit of FIG the traffic program memory VPS is not connected directly to the interrogation device AE for receiving identifiers, but rather receives all the required information, in particular the identifier of a peripheral tax rate that emits an incentive and the target information belonging to this incentive from the comparator VE. The comparison device VE is in turn connected to the interrogation device AE and the associative license plate memory AKS or the output memory AS and is also connected to a counter Z, which is used when a conveying container is discharged from an actuating device is advanced by one unit.

The associative identifier memory AKS, like the associative identifier memory of the program control unit according to FIG. 3, is arranged word by word, but the = ¹ individual words contain three pieces of information, namely the identifier of the setting device, the associated target information and the resulting counter reading.

If there is an incentive from one of the peripheral tax rates PS1 to PSn will be used after the identification of this

stimulus's offered by the interrogation device AE the corresponding identifier of the comparator VE. Be one after the other hun from the associative code memory AKS via the Output memory AS all words of the comparator VE cyclically offered one after the other. The Vergieichereinrichtüng VE transfers when the first word occurs with the Interrogation device AE given identifier corresponding identifier the entire word including the target information and the Counter reading to the comparison buffer ZSV. With everyone If another word with the same identifier occurs, a check is now made in the comparator device to determine whether the count of the word is correct in the comparison buffer ZSV is less than the counter reading of the just from the associative number plate memory AKS selected word. If this is the case, the latter word is stored in the comparison buffer ZSV instead of the former enrolled. After cycling through all the words of the associative license plate memory AKS is the word with the lowest in the comparison buffer ZSV Meter reading; this means that in the course of the delivery process from the control device with the examined identifier first abandoned conveyors are also treated first, as the the target belonging to it is present in the comparison buffer ZSV.

The term '' lowest meter reading "is to be understood as that not only the counter value contained in the queried word, but also the current status of the counter Z is taken into account. Since the counter Z must have a limited number of digits, a reset to the smallest counter reading, with this then opposite - in itself Higher value - counter values of others still in the associative Kehhzäicheü memory AKS of standing words not as a lower counter element is to be viewed *

The Eörmungsinformation available in the comparison buffer ZSV and target information is thereupon - as already with regard to of Figures 2 and 3 described - the traffic program memory VPS transfer the route data to örmittöi-6 and this is stored in the intermediate memory ZSP. The testing and setting device PEE then checks the peripheral again Tax rates, which are assigned to the actuating devices located in the course of the determined route, to their occupied status and then, if there is no busy case, the setting of the "perIph6ren tax rates" corresponds to the target information by.

will be described below using an example of funding.

It is initially assumed again that a conveying container is to be introduced into the conveying system at the actuating device assigned to the peripheral tax rate PSV. This request to listen in generates an incentive on the stimulus line AU, which is searched for by the interrogation device AE and identified as the identifier assigned to the peripheral control record PS1. An acknowledgment signal is then emitted via the stimulus line AU, which in turn leads to the connection of the peripheral control set PS1 to the standardized control lines NS1. When the acknowledgment code is output, the interrogation device AE causes the test and setting device PEE to connect to the standardized control lines NS1 and to check whether the setting device assigned to the peripheral control record PS1 is a setting device with target information. In the event that corresponding signals are present on the standardized control lines carrying the target information, that is, the peripheral control rate PSIaIg is recognized as a control rate which delivers target information, the counter reading of the counter Z is increased by one unit by the testing and setting device PEE, while the input memory ES is at the same time the identifier of the peripheral control record PS1, the target information and the ^{counter reading increased by 1} I 'takes over. The comparison device VE then takes over the identifier of the peripheral tax rate PS1 from the interrogation device AE; If the peripheral tax rate PS1 had not contained any target information, this transfer of the identifier of the peripheral tax rate PSt would take place directly after the connection of the peripheral tax rate PS1 to the standardized control lines NS1. After the identifier has been accepted by the comparator VE, all the words of the associative identifier memory AKS are offered to it cyclically via the output memory AS.

The Vergieichereinriehtung VS speaks on the first word the sender identification - which is already available via the interrogation device AE - and writes the corresponding V.'ort including the Target information and the counter status in the comparison buffer ZSV. All subsequent places with the same identifier are stored with the one stored in the comparison buffer ZSV "." place then compared whether their counter reading is lower than that of the latter word. At the end of such a cycle, the memory word is in the comparison buffer ZSV with the lowest count. ·

The comparison buffer ZSV then transfers the ID of the peripheral tax rate PS1 and the aaaoala « tive license plate memory AKS taken target information from the traffic program memory VPS, which is the two pieces of information forwards determined route data via the intermediate memory ZSP to the testing and setting device PEE.

In the event that the testing and setting device PEE recognizes a peripheral tax rate lying in the course of the path determined in this way as occupied, the ranking of the peripheral tax rate PS1 is increased, whereupon the program control unit PSE goes over to processing further requests.

If, on the other hand, the testing and setting device PEE recognizes the determined path as free, then the Adjustment of the corresponding setting devices by means of the ■ these associated peripheral tax records and then the signal transfer to these peripheral tax records that have the same as busy. Finally, a trigger signal is then sent to the peripheral control set PS1.

In addition, the target information is stored in the associative license plate memory AKS is deleted and the value of the counter is increased by H 'j these "two gates are set by the testing and metering device PEE controlled,

For the Pail that the next recipient, for example an adjusting device with a reading device, the target information of the conveying container is still required, the testing and setting device PEE gives the identifier of this setting device corresponding peripheral tax rate 'to the input memory, This identifier - through the counter reading and either the VE comparator or the output memory AS removed target information supplemented - writes into the associative license plate memory AKS; then the program control unit releases the control process.
