Description

2 AT 501 626 B1

The invention relates to an electrically controllable conveying device for piece-like conveyed goods, as described in claim 1, as well as a composite of several conveyors conveyor system, as set forth in claim 15. From CH 678 715 A5 a conveyor system with a plurality of conveying devices and an electronic control device is known. This conveyor system has a plurality of conveyor units, each with at least one conveyor. Each of the conveying devices has at least one movable, electrically controllable conveying member and at least predominantly at least one detector in order to determine the presence of an article to be conveyed or its position and / or the position of a conveying member in a sensory manner. For each conveyor unit one of these associated control unit is present with a digital subscriber computer. Each control unit is electrically connected to each controllable motor, each controllable actuator and each detector of the respective conveyor unit. At least a portion of the subscriber computers is networked and programmed with one another via a bus line, in order to control the conveyor devices at least in part because of the information exchanged between the networked subscriber computers. Furthermore, the subscriber computers are connected via this bus line with a hierarchically higher-level control computer, which in turn can be connected to a hierarchically superior central computer. By dividing the control functions on several interconnected control units 20, the manufacturing costs and the susceptibility to failure are to be reduced and also subsequent changes in the conveyor systems should be facilitated. However, the described control structure with several decentralized control units does not meet all the requirements for a modular, simple control for conveyors. 25 US 2004/0195078 A1 describes various types of conveyor modules for forming a comprehensive conveyor system. The individual conveyor modules in this case have a plurality of sensors and actuators, which are connected to a local control device on each conveyor module. In this case, the control device comprises a first interface type in order to provide a cost-effective, standardized fieldbus system, such as, for example, PROFIbus, build and 30 to connect a plurality of engine control devices. In particular, a control device is formed on at least one of the conveyor modules, which can be coupled via this cost-effective, standardized, first fieldbus system with a plurality of motor control devices of a plurality of conveyor devices. In addition, the control device of the conveyor module via a further interface of another type, for example an Ethernet interface or a PROFInet interface, with a higher-level section control controller or with a so-called material flow computer, e.g. in the manner of a PC, connected. The control device further has a same type, second interface, in particular a second Ethernet interface or PROFInet interface to the control device of the conveyor module also with a further control device of another conveyor module 40 data-technically coupled. The disadvantage here is that when building a contiguous network network occasionally additional network components are required to build a coherent data network between the individual conveyor modules and the parent material flow computer to. DE 91 06 384 U1 describes a generic system for transporting objects along a transport path subdivided into individual path sections, wherein at least one drive is provided per path section. Furthermore, an independent controller is provided for each path section, these signals being received by the control units of the immediately adjacent path sections. The control units successive so path sections are connected in series, a communication takes place only between adjacent control units. In the case of a supplement to the transport system, the control of the newly added or inserted drive with the control unit of the upstream drive and / or the control unit of the subsequent drive is connected. All control units have a connection for detecting the position of the control unit within the sequence of control units. Necessary for this automatic detection is a sequential 3 AT 501 626 B1

Series connection of the control units of the individual path sections. The sensors present per conveyor section report to the control unit the occupancy of the associated conveyor. The arrival of a conveyed goods, or the availability of a conveyed at the end of the conveyor is reported to the control unit, which then initiates a corresponding action. 5 The communication between the individual control units takes place between control units directly adjacent path sections, wherein adjacent control devices are connected via connectors in series with each other, thus resulting in a sequential communication connection. io too. DE 42 36 536 A1 describes a transport system for transporting objects along a predetermined path. The individual control units are combined to control strands, wherein the individual control units of a control string are interconnected only with the adjacent control or drive unit; the terminal control unit on one side of the Steuerstrahgs is connected to the control center. The control 15 software is stored in a programmable read-only memory (EPROM), therefore, the software module of the associated control unit must be replaced if the controller is to be used with another drive control. In an extension of the control device further control units are connected to the terminal switching group. Information and data signals are forwarded sequentially within a control string from the 20 control units and finally transferred from the terminal control unit to the control center. The communication between control units of different control strands takes place via the control center.

Also US 6,244,421 B1 describes a control system for a conveyor for transporting 25 individual goods along a conveying path. The conveying path is divided into individual zones, each zone containing its own control module.

At the end of each individual zone seen in the transport direction, a sensor is mounted. This signalizes to the control module whether the goods 30 transported by the respective zone are already at the end of the zone. A control system, which is connected to the subsequent and upstream conveyor, allows a different transport speed for two transported goods in the subsequent or upstream zone in the case of a different coefficient of friction between the first and second conveyed and the subsequent or upstream conveyor. 35

US 2004/0084284 A1 describes a system for decentralized control and voltage. Supplying a conveyor divided into four sections, each zone being subdivided into four zones. For each conveyor, a controller is provided, therefore controls a controller a total of sixteen adjacent zones. The individual control units of the entire conveyor system are interconnected and connected to a central controller. A bus master card in the central controller (usually a personal computer) can manage up to 64 nodes, resulting in a maximum of 1024 manageable zones. A powerful personal computer as a central controller, can manage a maximum of seven bus master cards. The maximum number of manageable zones is therefore given as 7 * 1024 45. The individual control devices are connected to each other via a respective data interface and to the central controller.

US 6,701,214 B1 describes a control system of a modular conveyor system which can be networked with other such systems to form together a conveyor system. Each control system includes a communication port for connection to a network for exchanging addressed messages. The network for address-based data exchange allows a simple configuration; a change in the configuration of the conveyor system is easily possible from a central location. If, owing to the requirements of the conveying path, the need for division 55 of the conveying path arises, the sequential connection of the individual control systems 4 A 501 626 B1 must be interrupted and a splitting of the network into two branches must be carried out by means of a network bridge.

The present invention has for its object to provide an electrically controllable conveyor device for forming a continuous, branched conveyor system, which allows a simple construction of a comprehensive data network between the individual conveyors. In addition or nonetheless, an increased availability or reliability of a conveyor system formed from a plurality of conveying devices is to be achieved.

Regardless of this, a further object is to provide a conveying device or a conveying system which has the highest possible transport rate for conveyed goods and nevertheless achieves reliable transport of the conveyed goods.

The first object of the invention is achieved by a conveying device according to the features in claim 1. An advantage of the conveyor device according to the invention is that complex or extensive conveyor systems can be constructed without the necessary control system becomes unmanageable or uneconomical. In particular, due to the simple data linkability of the control device of a first conveying device with the control device of a further conveying device, a continuous data network incorporating either all or most of the conveying devices can be easily built up. Of particular advantage is further that minimum cable lengths are executable to network the conveying devices of a modular composite conveyor system control technology. The relatively short cable lengths between the communication interfaces of two control devices thus result in a reduction in the construction costs. Of particular advantage is that the technical clarity of the system or the control network is hardly affected even with complex conveyor systems due to the relatively short cable lengths and the reduced number of cables. An advantage of the assignment of a control device to a modular conveyor device is also that subsequent changes, extensions or other interventions are relatively easy to perform in the control system. In addition, the performance or computing performance of the overall control system is always increased or at least partially tracked in a subsequent extension of a conveyor system with additional conveying devices.

Another significant advantage of the conveyor device according to the invention is that a composite conveyor system consists of a plurality of uniform or identical control devices, so that a high efficiency in the construction of a large conveyor system can be achieved. A particular advantage of the multiple trained, same type communication or data interfaces on the control device of the conveyor is also that branched conveyor paths can be realized in a particularly simple manner, without additional, the conveyor system more expensive network components, such. so-called switches or hubs are required. In addition, further conveying devices with communication-compatible control devices can be incorporated into the communication network in a simple manner at originally free communication interfaces. In addition, initially free or unoccupied communication interfaces can be used at any time to connect service or observation devices, as required, for example. mobile terminals. After such operating and / or observation devices can be integrated into the control system or into the data network at any point of a complex conveyor system as needed, the user can select a locally most suitable coupling position as far as possible. For example, this also makes it possible to carry out in a particularly simple manner with a mobile terminal certain commissioning or adjustment work on that location of a conveyor system, where a particularly good visibility is given to the technical process or to the respective conveyor. 5 AT 501 626 B1

It is also advantageous if in the multiply arranged, functionally or communication physically identically executed communication interfaces for establishing a communication connection with at least one conveyor are designed randomly assignable, as a subsequent extension or modification of an originally present 5 structure without special knowledge of the control technology can be made in a simple manner.

Of particular advantage is also a development according to claim 2, since in an assembled from several conveyors conveyor system increased Fehlertole-io rancidity or increased reliability is achieved. In particular, resulting from the annular closed communication path between the control devices of multiple conveyors redundant communication paths, which can ensure a maintenance of the operation or the function of the conveyor system even if one of the communication channels, for example, by a cable break or other disturbances in un-predictable Way was interrupted. Moreover, by deliberately forming annular data networks between a plurality of control devices of the conveyor system, the transmission time of data packets of a first subscriber to another subscriber can be reduced, since this data transmission can take place via a communication path in which comparatively fewer control devices are integrated or in which a 20 comparatively low network load is present.

The advantage of the embodiment according to claim 3 lies in the fact that a multiple arrangement of a standardized Ethernet communication interface is carried out, whereby a reliable and cost-effective construction of a data network between adjacent or to each 25 stringed conveyors is possible.

Another advantage is the embodiment of claim 4, as a result, a routing function is quasi integrated into the control device and thus structurally independent, costly routers are unnecessary. In addition, a compact control structure is made possible, since preferably no external network router or switches are required in order to achieve an orderly data exchange or a correct data transmission in the data network. Namely, the address-based data transfer is advantageously managed by the control devices of the conveyors themselves. The embodiment according to claim 5 guarantees a fast transfer of information or data within the data network between the conveying devices.

The further development according to claim 6 ensures that priority is given to processing those data packets or information which are of increased importance for a proper or scheduled transportation of goods.

The embodiment according to claim 7 ensures that particularly important information is processed or processed with priority and that no time-increasing blocking of data with increased priority can occur. 45

Another advantage is the embodiment according to claim 8, as a new or reprogramming and / or observation of the control processes at that point of a complex conveyor system can be made, at which given a good visibility on the technical process or the respective control processes is. The localized so connectability of the operating and / or monitoring device also reduces the risk of erroneous operations or programming a particular conveyor within a complex conveyor system.

It is also advantageous embodiment according to claim 9, since all or at least 55 several types of conveyor modules are provided with one and the same control device, so that a modular compilation is simplified to a comprehensive conveyor system. Of particular advantage is further that the multiply formed communication interfaces are also formed on conveying devices with at least one conveying path branching. Especially in so-called node modules or crossing modules no additional network components are required for a data link with three or more subsequent conveyors, which would have to be integrated with additional effort in the data network between the various conveyors.

By using additional measures according to claim 10, the basis for an io dynamic maintenance detection and remote maintenance capability is created, with such a load-oriented or event-oriented maintenance being economically implementable, above all by a distributed control intelligence with a plurality of controllers.

But the development according to claim 11 is economically implementable when using a control device with 15 decentralized control modules or control devices. It is advantageous that it is possible by a detection or measurement of noise, vibration and the like, relatively reliable and yet uncomplicated to early detect any unwanted changes within the technical system and initiate preventive measures in a timely manner. As a result, a high system availability or increased reliability of the delivery device 20 is achieved.

By the measures according to claim 12, the elicitation of errors or unfavorable processes is simplified. In addition, system optimization can be carried out without problems after the relevant data has also been logged in the memory proto-25 for past periods and can be subsequently evaluated at any time via the head station or the material flow computer.

In the embodiment of claim 13 is advantageous that the performance of the conveyor or a composite conveyor system can be continuously optimized. Also, this improvement of the conveyor device is particularly economically feasible only by the formation of decentralized control devices in the conveyor system.

The development according to claim 14, an at least partially automated generation of operating software for the conveyor is possible. In particular, it is advantageous that the conveying device or its control device can be equipped at an early stage with a uniform control software, which is identical for all control devices, so that the required basic functions can be fulfilled. Any additional or special functions can be implemented at any time in a simple manner by additional software modules. In particular, automated software generation for the programming of the electromechanical conveyor modules can be carried out at least partially using appropriate software tools. Optionally, depending on the layout of a composite conveyor system, an assignment of the particular logistic function, e.g. due to the neighborhood relationship of the respective conveyor, at least semi-automatically done. Such software generation for various Fördervorrich- 45 tions may be accompanied by query dialogues or run fully automatically based on the system layout. After a preferably performed plausibility check, a completely generated software module or control program can be loaded directly or via the data network into the control device of the corresponding conveyor device. The invention also includes a conveyor system as described in claim 15. An advantage of such a conveyor system is that there is a modular or modular system that extends from the mechanical conveyor modules to the modular control components. A significant advantage here is that almost arbitrarily complex conveyor systems can be set up without the need for external network components or network distributors, in order, for example, to use e.g. in the case of conveyor branches, the data network can be continued or continued. This reduces the cost of the conveyor system, which provides significant benefits for the producer as well as for the operator of the conveyor system. In addition, such a continuous modular conveyor system is relatively easy changeable or expandable, since on the one hand, the mechanical conveyor modules and on the other hand, the electrical control technology modules can be relatively easily put together in functional operative connection.

The invention will be explained in more detail below with reference to the exemplary embodiments illustrated in the drawings.

In the introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals and the same component names, wherein the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as above, below, 35 laterally, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions. 40

In Fig. 1, a modular conveyor system 1 for piece goods 2 is exemplified. The chunky conveyed material 2 may be formed, for example, by packages, containers, workpiece carriers, workpieces or trays, pallets, etc., which within the constructed conveyor system 1 by means of several modular composite conveyors 3, 45 4, 5 to different, respectively desired or required positions can be spent. The individual processes in the conveyor system 1 shown by way of example run at least partially automatically, for which purpose an electrical control system 6 is embodied, which comprises a plurality of electrical or electronic control devices 7. In particular, each of the conveying devices 3, 4, 5, or at least most of the structurally autonomously designed, modular conveying devices 3, 4, 5 has its own control device 7 at least for the automated control of the functional sequences of the respective conveying device 3, 4, 5. The control devices 7 are connected to one another via a standardized data bus 8 known from the prior art, so that the individual control devices 7 are connected to each other via a data network 9 in a data-technical connection. 55 By the control devices 7 connected to the data network 9 is between the 8 AT 501 626 B1

Control devices 7 of the various conveyor devices 3, 4, 5 an orderly data or information exchange or rapid data transmission allows without a large number of information or data lines is required. By means of the control technology coupled to each other control devices 7 so a basis for a plangemäßen control 5 erungsablauf within the composite conveyor system 1 is created. In particular, an automated, scheduled operation of the conveyor system 1 is ensured by functional interaction of the local, in each case control technology intelligence having control devices 7 to the individual conveyor devices 3, 4, 5. Via the data bus 8, inter alia, also control-related or process-relevant information is transferred between the conveyor devices 3, 4, 5 which follow one another in the direction of conveyance 2, or between their control devices 7.

The complete control system 6 for the conveyor system 1, for example, also includes a control computer 7 superordinate control computer or a so-called material flow computer 10. This material flow computer 10 can also be integrated via a data bus 8 in the data network 9 with the individual control devices 7. The material flow computer 10 may be formed by any programmable logic controller or by an industrial personal computer or by other, processing control programs, computing unit. The material flow computer 10 in turn 20 can be coupled according to an extended embodiment with a central, resource-managing host computer 11, the processes or functionalities of the conveyor system 1 depending on the resources or requirements within a technical system, for example, within a goods or Warehouse or a baggage handling system, determined or managed. Likewise, the host computer 11 may be connected directly to a control device 7 or to a plurality of control devices 7.

The host computer 11 counts in particular to the highest level of plant control and can be part of a so-called ERP system (Enterprise Resource Program System). Rather, the material flow computer 10 can be understood as a structurally independent master control to which the individual, decentralized control devices 7 are connected in the manner of intelligent slave controllers.

The individual control devices 7 are successively connected to one another via the data bus 8 and coupled to the material flow computer 10 via this data bus 8. The control architecture between the individual control devices 7 and the material flow computer 10 thus comprises decentralized, control-technically intelligent or at least partially autonomous control devices 7. The network architecture described below offers considerable advantages over the conventional architecture which requires star-shaped or tree-shaped cabling 40, as will be explained in more detail below.

As best seen in Figs. 2, 3, the generally self-contained, i.e. actively conveying, modularly constructed conveying devices 3, 4, 5 within a complex, composite conveyor system 1 at least occasionally an electro-niche or sensory detection device 12 and / or at least occasionally a drive device 13 for the implementation or execution of movements. The respective sensory detection devices 12 on the respective conveying devices 3, 4 are connected to the local control device 7 of the respective conveying device 3, 4, in particular to the corresponding inputs of the control device 7. In addition, each of the existing drive devices 13 or each actuator, which is mounted or arranged on a single conveyor device 3, 4, 5 for implementing motion functions, is connected to the corresponding outputs of the control device 7. On the basis of control or sequence programs, which are to be processed by the various control devices 7 or by logical links of the sensory detected conditions or on the basis of other, control-relevant conditions, if necessary, by incorporating information from 9 AT 501 626 B1

Material flow computer 10 and / or information from neighboring, i. of upstream and downstream conveyors 3, 4, 5 and their control devices 7 of the respectively desired or required, initial state produced by the corresponding actuator or the corresponding drive device 13 is activated or deactivated. A program-5 technical linkage of inputs of the control device 7 and an automated state change to the corresponding outputs of the control device 7 is well known to those skilled in the art and can be found for this most diverse versions of the prior art, which is not closer to the control or programmtechnischen Functions is received. In any case, each of the local control devices 7 on each of the self-functioning, modular conveyor devices 3, 4, 5 at least for controlling the associated conveyor device 3, 4, 5, wherein on the basis of data or control commands, which are transmitted via the data network 9, and optionally based on information or states which were determined via the local detection device 12, the corresponding output states or target states of the conveyor device 3, 4, 5 or of the total 15 carried out conveyor system 1 are manufactured or implemented automatically.

In order to be able to receive information relevant to the operation of neighboring, in particular of upstream or downstream conveying devices 3, 4, 5 or to transmit such operationally relevant data or information and to incorporate this information into the control processes or to process it programmatically or via logical To connect functions according to the Boolean algebra, each of the control devices 7 preferably wired or line-bound communication interfaces 14 for data communication with the control device 7 from or to at least one of the adjacent or adjacent conveyor devices 3, 4, 5. In particular, the control devices 7 of the various conveyor devices 3, 4, 5 are coupled to one another via the communication interfaces 14, which are respectively formed on the individual control devices 7, in terms of data or control technology. Preferably, a serial connection between the control devices 7 of the individual conveying devices 3, 4, 5 is formed. That is to say that the data bus 8 is routed in a chain-like manner from one control device 7 to the next control device 7, so that the individual control devices 7 of the various conveying devices 3, 4 are lined up in a serial or chain-like manner and form the common data network 9 via the common data bus 8 , in which preferably also the material flow computer 10 (FIG. 1) is integrated. Preferably, the control devices 7 of the immediately adjacent conveying devices 3, 4, 5 are connected to one another via the data bus 8 in order to achieve the shortest possible cable lengths. In principle, however, it is also possible for the control devices 7 to be relatively data conveyers 3, 4, 5 via comparatively widely spaced conveying devices 3 via the data bus 8. to couple control technology. 40

It is essential that each control device 7 at each electrically controllable conveying device 3, 4, 5 of the conveyor system 1 at least three, preferably four uniformly or identically executed communication interfaces 14 for data connection to communication-compatible control devices 7 immediately adjacent or the conveyor line continuing 45 conveyors 3, 4, 5. These per control device 7 or per modular conveyor device 3, 4, 5 multiply, in particular at least three times, preferably four-way arranged communication interfaces 14 are functionally or structurally similar and designed to match their type or genus. Preferably, these multiply, in particular at least three times, but for example also five or six times built on the control devices 7, indiscriminate or same type formed communication interfaces 4 to build the data network 9 between the individual conveyor modules or conveyor devices 3, 4, 5 indiscriminately or executed as required. That in that the at least triple, preferably fourfold, communications interfaces 14 on each of the control devices 7 can be used to establish a communications link between the control devices 7 without a fixed ranking or without a specific assignment order, for information purposes -respectively. Build data network 9 between the individual control devices 7. In the case of linear or rectilinear conveying devices 3, 4, which are lined up substantially without gaps to achieve the required conveying path or conveying length and are connected to each other via the data bus 8, at least one communication interface 14 thus remains unchecked per control device 7 if three similar communication interfaces 14 are activated the control device 7 are executed.

Preferably, individual, the data bus 8 forming cable connections, which each have electrical plug devices or connectors at the two cable ends, from a control device 7 to the next or subsequent control device 7. In particular, between two adjacent conveyor devices 3, 4 arranged conveying device 5 bzw. their control device 7 by means of two separate cable connections, in particular by means of two so-called patch cables, connected via a first cable connection to the conveyor section, upstream conveyor device 3 and a second cable connection with the related to the conveyor section, downstream conveyor device 4, as the Representation of FIG. 1 is easy to see.

As a result of the above-described multiple arrangement of communication interfaces 14 on the control devices 7, at least one communication interface 14 usually remains unoccupied at the various control devices 7, these being connected at any time or, if required, for connecting a mobile operating and / or monitoring device, e.g. in the manner of a handheld terminal, and / or for connecting the material flow computer 10 can be used. Independently of this, a remote maintenance system or a so-called remote control system can be integrated via the data bus 8 and an unoccupied communication interface 14 of the control devices 7.

After a plurality of such communication interfaces 14 usually remain unoccupied in a conveyor system 1 consisting of a plurality of conveyor devices 3, 4, 5, a locally ideal selection or connection of a still free communication interface 14 is made possible by the operator or user. In addition, a particularly flexible extension of the control system 6 can be made after a plurality of locally distributed positions within the conveyor system 1 for extensions or additional connections are available.

The specified multiple arrangement of the functional or communication-physically identical communication interfaces 14 on at least one conveying device 3, 4, 5 of a complex conveyor system 1 offers a number of advantages already described above. An advantageous conveyor device 3, 4, 5 with at least three, preferably four uniformly executed communication interfaces 14 can of course also be coupled to a conveyor module, which has less than three, for example, only two, uniformly executed, communication-compatible communication interfaces.

The above-described sensory detection devices 12 on the various conveyor devices 3, 4, 5 can be formed by any known from the prior art sensors, encoders or switches. In particular, sensors can be used in accordance with any physical principle of action to detect or detect operationally relevant states and to be able to evaluate them in terms of electrical engineering or control technology. Preferably, at least one opto-electric light barrier is arranged as the detection device 12 in order to be able to automatically determine the presence and / or the position of a conveyed material 2 to be conveyed. However, the sensory detection device 12 may also include sensors or encoders or switches which are provided for determining positions or operating states of the conveying elements of the conveying device 3, 4, 5. 1 1 AT 501 626 B1

The drive devices 13 described above are understood to be any drives or actuators known from the prior art. Under the umbrella term "drive device 13" fall in particular electrical, pneumatic, hydraulic or other drive motors. Under drive devices 13 but also actuators or switching valves 5 are to be understood, which can activate or deactivate movement drives. In particular, solenoid valves are to be understood as a drive device 13 or as a control-engineering actuator.

The modular conveying devices 3, 4, 5 of the conveyor system 1 have at least occasionally an io controlled movable conveying member 15. In the illustrated embodiment, the conveyor devices 3, 4, 5 rotatably mounted or displaceable in active rotational movement conveyor rollers 16 for the transported material to be transported 2. The conveyor devices 3, 4, 5 shown in FIGS. So are formed by so-called roller conveyor. Alternatively or in combination with such roller conveyors can be designed as a conveyor device 3, 4, 5 but also belt conveyor 15 rer, belt conveyors, lifting or lowering platforms, curved conveyor and the like to form a coherent conveyor system 1 in combination. Each module-like conveying device 3, 4, 5 comprises at least one associated control device 7, which is designed for the control technology implementation of the basic functions of the respective conveyor device 3, 4, 5. 20

In the illustrated embodiment, a plurality of conveyor rollers 16 of a conveyor 3, 4, 5 via suitable coupling mechanisms, such as. Belt or gear connections, motion coupled and by means of a drive motor at least unidirectional, preferably bidirectional, driven. 25

4, an exemplary structure of a conveyor system 1, consisting of a plurality of individual conveyor devices 3, 4, 5 schematically illustrated. At least some of the individual conveying devices 3, 4, 5 have the control device 7 at least for controlling the sequences or functions of the respectively associated conveying device 3, 4, 5. Preferably, a control device 7 is formed per separate conveyor module. The conveyor system 1 thus has a control system 6, which comprises a plurality of distributed control devices 7, so that a predominantly decentralized or distributed control architecture is present. As already described above, the individual control devices 7 are connected in series to a data network 9 by means of a data bus 8, which enables regulated information or data exchange between the control devices 7 within the data network 9. As has already been described above, the data network 9 between the distributed control devices 7 is also connected to a control-material superordinated material flow computer 10. The material flow computer 10 is preferably integrated via the same or matching data bus 8, preferably via a so-called Ethernet connection, into the data network 9 between the control devices 7 or between the individual conveying devices 3, 4, 5. For this purpose, the material flow computer 10 is preferably at any point of the conveyor system 1 via a standardized cable connection for the data bus 8, in particular via a so-called patch cable to a free communication interface 14 of the Fördervorrichtun-45 conditions 3, 4, 5 connected.

According to an advantageous embodiment, the material flow computer 10 is connected via at least one further cable connection, in particular via a second data connection 17 at another point of the conveyor system 1 or via a further conveyor device 3, 4, 5 in the data network 50 factory 9 with the control devices 7 , The additional data connection 17 between the material flow computer 10 and the data network 9 is preferably identical in terms of its type to the data bus 8 or identical to the type of the data network 9. Preferably, the data connection 17 is therefore formed by a further Ethernet connection, via which the material flow computer 10 at a further layout position of the Fördersys-55 tems 1, in particular via a per se, free or unoccupied communication interface 14 1 2 AT 501 626 B1 another control device 7, data technology integrated into the data network 9.

As previously described, the material flow computer 10 may communicate over a local, standardized network connection 18, such as a network. a standard Ethernet connection (LAN), to be connected to a higher-level host computer 11. This host computer 11 can, as shown schematically, be formed by a single arithmetic unit or else be realized by a plurality of arithmetic units. The host computer 11 or the group of several networked data management systems can take over functions for a computer-aided warehouse management and / or a goods management or for an organizational management of a company or a company.

The control system 6 for the conveyor system 1 may also comprise at least one mobile operating and / or monitoring device 19. This operating and / or observation device 19 is preferably formed by a portable terminal 20, which allows a reprogramming and / or observation or verification of the control-technical processes of the control system 6. For this purpose, the mobile operating and / or observation device 19 at any point of the conveyor system 1 in the data network 9, which is constructed between the control devices 7 of the individual conveyor devices 3, 4, 5, integrated or integrated data technology. In particular, the mobile operating and / or observation device 19 can be connected via a data cable 21 to a free or unoccupied communication interface 14 of any control device 7. Preferably, each of the control devices 7 in the data network 9 to a unique address or distinctive identifier, as is well known in the prior art. In the illustrated embodiment, the operating and / or monitoring device 19 has been connected to a free communication interface 14 of the control device 7 with the address or identifier 22. In an advantageous manner can be made by the multiple arrangement of the communication interfaces 14, the connection of the mobile operating and / or observation device 19 in the vicinity or close range of those conveyor 3, 4, 5, in which programming or observation activities by an authorized operator or Administrator are necessary. The optional attachability of the mobile operating and / or monitoring device 19 at a plurality of possible locations within the conveyor system 1, a good visibility of the respective processes is guaranteed, so that the likelihood of possible operating errors or incorrect programming of the respective conveyor 3, 4, 5 essential can be reduced.

Alternatively or in combination with a wired integration of a mobile operating and / or monitoring device 19 in the data network 9, this data or control technology connection can also be made via a wireless or contactless data interface 22. This wireless data interface 22 of the mobile operating and / or monitoring device 19 is provided for a contactless data exchange within a radio network 23 (WLAN). The material flow computer 10 preferably forms an access component 24, in particular a so-called "access point" for the radio network 23, or an access component 24 for a standardized radio network 23 is connected to the material flow computer 10. Alternatively, it is also possible to assign the access component 24 for a radio network 23 to a head end 37 (FIG. 5).

According to a conceivable alternative, at least a part number or all the control devices 7 of the conveying devices 3, 4, 5 can be in data communication with one another via a radio network 23, for example a standardized WLAN data network, and the required information, data or commands can be wireless or contactless change. The communication interfaces 14 on the control devices 7 are formed for the alternative case of the formation of a radio network 23 by transmitting and / or receiving antennas for electromagnetic waves.

4, the control devices 7 on the various conveyor devices 3, 4, 5 are designed to set up at least one annularly closed communication path 25 between the control devices 7 of a plurality of conveying devices 3, 4, 5 , That is, the data network 9 between the control devices 7 may comprise a circular closed communication path 25 or a plurality of annularly closed communication paths 25 between individual groups of control devices 7. In particular, at least one subset of the control devices 7 is interconnected in a circular fashion via the data bus 9 or is networked together in a ring shape. In particular, a structurally endless communication path 25 is established between a plurality of control devices 7 or between a plurality of conveying devices 3, 4, 5. 10

In the illustrated embodiment, a first control device 7, e.g. with the address or identifier 4 with further control devices 7 with the identifiers 5, 11, 15, 14, 13, 10, 3 connected in series. In addition, the last control device 7 is connected to the address 3 in the chain-like networked control devices 7 via a ring closure connection 26 with the 15 quasi first or initial control device 7 with the identifier 4. This ring connection 26 is formed in a simple manner by a data cable which is identical to the data cables or connecting cables between the other control devices 7 of the data network 9 is executed. Such a ring closure connection 26 between a plurality of control devices 7 and the formation of at least one annular communication path 25 increases the availability of the conveyor system 1 substantially. In particular, multiple or redundant communication paths between the control devices 7 are created by the construction of the annular communication path 25 between a plurality of control devices 7 or due to the ring closure connection 26. For example, e.g. when, between the control device 7 with the identifier 4 and, for example, the material flow computer 25 or the head station 37 a uni- or bidirectional data exchange is to take place, this usually via the shortest serial data connection between the control devices 7 with the identifiers 5, 11, 15, 19, 21 realized. However, if there is an interruption of the shortest, usual communication path between the control device 7 with the identifier 4 and the material flow computer 10 or the head end 37 - as described e.g. can occur at a 30 cable break or other defect - so can the corresponding information about the control devices 7 with the identifiers 3, 10, 13, 14, 15, 19, due to the annular communication path 25 and due to the ring closure 26 in the data network 9 21 are transmitted to the material flow computer 10. Of course, an information or data transmission, for example, starting from the material flow computer 35 10 or starting from the head station 37 via this alternative, redundant Oatenübertra- supply path to the control device 7 with the identifier 4 is possible. By targeted construction of annular closed communication paths 25 between a plurality of control devices 7 so a communication redundancy is created, which nevertheless allows a 40 maintenance of the operation of the conveyor system 1 in case of failure of individual data connections between the control devices 7 in an advantageous manner. The plant availability is thus increased, so that a significant benefit or advantage for the user of the conveyor system 1 can be set, after the reliability is increased accordingly.

A particular advantage of this communication redundancy via the at least ring closure connection 25 or via the at least one annular communication path 25 is also that an emergency stop or emergency stop with increased reliability or safety can be initiated. In particular, such a stop command for the conveyor system 1 or for at least one conveying device 3, 4, 5 can also be implemented if the actually provided signal path is not available for unforeseeable reasons or if the basically responsible signal path has been interrupted. In addition, by forming a ring closure connection 26 between a plurality of control devices 7, the reaction time to general control commands or to a quick stop command (emergency stop) can be minimized. This is especially true if such, possibly time-critical shutdown or stop commands are to be transmitted between one of the control devices 7 and the material flow computer 10 and / or the host computer 11. However, a transmission of such stop commands may also be necessary starting from the material flow computer 10 and / or host computer 11 to one of the control devices 7 or conveying devices 3, 4, 5 in the conveyor system 1 reliably and within the shortest possible time.

After the control devices 7 have at least three, preferably four uniformly executed, preferably contact-type or electrical communication interfaces 14 for forming the data network 9, an annularly closed communication path 25 can be built up, without additional components, such as e.g. Switches, hubs or the like., To integrate into the data network 9. An advantage of this multi-port solution to the control devices 7 of the conveyors 3, 4, 5 is therefore also that no more expensive, additional network components must be integrated into the data network 9 and still an advantageous communication redundancy can be created in a simple manner by a communication or signal-technical ring closure connection 26 between the first control device 7 and the last control device 7 within a group of a plurality of conveying devices 3,4, 5 can be constructed.

The conveying devices 5 with the addresses or identifiers 3, 5, 8, 23 and 15 shown schematically in FIG. 4 each have at least one conveying path branch 27, 28 or allow these conveying devices 5 branches or branching of conveying links. In particular, these conveying devices 5 are formed by so-called node modules or crossing modules. Especially with such conveying devices 5 with at least one possible conveying path branch 27, 28, it is of particular advantage that their control devices 7 at least three or four with respect to their type uniformly or identically executed communication interfaces 14 for data connection to communication-compatible control devices 7 immediately adjacent or immediately following, the conveyor line weiteretzender conveyor devices 3, 4 have. In particular, continuations of the data network 9 can be created and / or annular communication paths 25 can be established without additional network components having to be integrated into the data network 9. As a result, on the one hand, a compact, manageable structure of the data network 9 is maintained and, on the other hand, expensive additional or distribution components in the data network 9 between the control devices 7 are unnecessary.

The formation of a ring closure connection 26 or a closed communication path 25 between control devices 7 of a plurality of conveyors 3, 4, 5 is basically not limited to conveyors 3, 4, 5, which are installed in a ring. In particular, even with a linear or tree-like constructed conveyor system 1 between individual control devices 7 or between individual groups of arbitrarily arranged conveying devices 3, 4, 5 ring closure connections 26 may be executed.

FIG. 5 illustrates a block diagram relating to a possible structure of the control system 6 for a complex conveyor system 1 (FIG. 4). This block diagram also depicts the hierarchy of the various components within the control system 6.

Starting from a control device 7 for a modular conveying device 3, 4, 5 (FIG. 4), a wide variety of subcomponents or peripheral devices are connected to the control device 7 of the respective ones via standardized bus systems, in particular via fieldbus systems 29 such as CAN, PROFIbus, DeviceNet and the like Conveying device 3, 4, 5 connectable. Peripheral components are barcode scanners or RFID (radio frequency identification j-readers 30, label printers and / or weighing devices 31 for transported goods and / or controls for building components, such as gate controls 32 for high-speed room dividers, such as shutters or blinds, to understand.

According to an advantageous embodiment, an image acquisition device 33, in particular a network-capable video camera or a so-called "webcam", is connected to the control device 7. Via this image acquisition device 33, it is possible to record the surroundings around the corresponding conveying device 3, 4, 5 in a video-like manner and to record the captured image or image. Transfer audio data over the data network 9 to widely remote locations, especially to globally distant locations. By means of this image capturing device 33 on at least one of the decentralized control devices 7, a remote maintenance or assistance in troubleshooting can be carried out in a simple manner, starting from widely spaced or globally remote locations in a simple manner.

The previously described, mobile operating and / or monitoring device 19 can either also be connected via a fieldbus system 29 to the control device 7 or be integrated via a blank communication interface 14 in the data network 9 between a plurality of control devices 7.

Furthermore, a plurality of input and output modules 34 for the control device 7 can be connected via the local control bus or field bus of the control device 7. These input and output modules 34 on the control device 7 allow the connection of any actuators or sensors. In particular, optionally required coding circuits, solenoid valves, heaters, temperature sensors, power drives, contactor circuits, engine starting devices, frequency converters and the like can be connected via the input and output interfaces of the input and output modules. Furthermore, a detection device 12 in the manner of a data light barrier for object detection can be integrated into the control system 6 via such an input and output module 34.

It is advantageous if the control device 7 also has an input and / or output module 35 with increased functional reliability or increased control priority. This highly secure input and / or output module 35 is preferably used to integrate at least one emergency stop switching device 36 into the control system 6.

The control devices 7 integrated in the data network 9 are also connected to the material flow computer 10 via this data network 9. Between the material flow computer 10 and the network of the control devices 7 and at least one optionally required control technology head station 37 may be arranged, which can take over central administration services or which may be required for the connection of the control devices 7 to the material flow computer 10 and which at least in part can take over the functionalities described for the previously described material flow computer 10.

At least one security-relevant or security-based control device 38 can also be embedded in the data network 9. This safety-based control device 38 is used to achieve or ensure a particularly person ^ and / or functionally reliable operation of the conveyor system. 1

In the data network 9 but also at least one stationary operating and / or observation device 19 (HMI: human-machine interface) can be integrated, as was exemplified in Fig. 5.

The material flow computer 10 for superordinate management of the material or transport flows can be coupled to an additional warehouse management computer 39 and / or to an electronic goods management system 40 and / or to a resource management system 41 (ERP). Optionally, the warehouse management computer 39 and / or the goods management system 40 and / or the resource management system 41 can also be integrated into the material flow computer 10 or form a subset of the material flow computer 10.

According to an advantageous embodiment, a remote connection computer 42, in particular a so-called remote PC, can also be integrated into the control system 6 for the conveyor system 1. This remote connection computer 42 is, on the one hand, technically coupled to the material flow computer 10 1 6 AT 501 626 B1 and / or to the data network 9 and, on the other hand, via a communication device 43, such as, for example, a modem or network router into a global communications network, e.g. the Internet 44, einbindbar. By means of this remote connection computer 42, it is possible to carry out certain remote maintenance activities, troubleshooting or administrative activities in the control system 6 for the conveyor system 1, starting from almost any location.

FIG. 6 illustrates an exemplary structure of the control device 7 for a conveyor device 3, 4, 5. The electronic control device 7 itself is preferably likewise of modular construction and comprises a program-controlled central unit 45 with at least one microprocessor for forming a programmable program-controlled automatic control. The at least three, preferably four, identical or uniformly executed communication interfaces 14 for on-demand connection to the control devices 7 of further conveying devices 3, 4, 5 (FIG. 1) are formed on this central unit 45.

To this central unit 45 a plurality of input and output modules 34 can be coupled. These input and output modules 34 have a plurality of inputs and outputs for the electrical connection of the various sensors and actuators of the corresponding conveyor device 3, 4 or 5 (FIGS. 2, 3). As is well known, the input and output modules 34 may also be a plurality of display devices 46, such as those shown in FIG. LED's, for visualization of the respective states of the inputs and / or outputs. At least one optical and / or acoustic display device 46 may also be embodied on the central unit 45. Optionally, the central processing unit 45 or the control unit 7 may also comprise an input device, such as an input device. Button, switch or the like., Have.

Depending on the application, the individual input and output modules 34 can correspond to a higher-valued or lower-grade protection class or insulation class (IP class). The individual input and output modules 34 are signal-coupled via a local communication bus 47 with the central unit 45. An advantage of the modular control device 7 for the various conveying devices 3, 4, 5 (FIG. 1) is that the functionality of the control device 7 can be easily removed in accordance with the respective requirements.

The control device 7, in particular its central unit 45, comprises at least one microcontroller 48. This microcontroller 48 is connected to the communication interfaces 14 of the control device 7. Among other things, the microcontroller 48 is programmed or implemented to implement an address-based routing function for data packets arriving at the communication interfaces 14. In particular, in the control unit 7 or in the microcontroller 48, a functionality similar to a so-called router is included. This advantageously makes it possible to use separate network components, e.g. Switches, unnecessary. Among other things, an increased compactness of the overall control system 6 (FIG. 1) is thereby achieved and, in addition, the susceptibility of the control system 6 to interference is reduced.

The microcontroller 48 is thus inter alia for the evaluation of the data packets or its addresses, which are received at the multiply, in particular at least three or four times arranged communication interfaces 14, is provided. Furthermore, this microcontroller 48 of the control unit 7 is provided for forwarding or transferring a received data packet to one of the further communication interfaces 14. The forwarding or transfer to the corresponding communication interface 14 takes place taking into account the destination address or taking into account the most direct possible communication path to the intended control device 7 within the data network. 9

In accordance with an advantageous embodiment, the at least one microcontroller 48 in the control unit is AT 501 626 B1

Device 7 of a conveyor device 3, 4, 5 (Fig. 1) for receiving and evaluating data packets with priority labels trained or programmed. In addition, the microcontroller 48 of each control device 7 within the conveyor system 1 (FIG. 1) is designed or programmed for generating and sending data packets with priority identifications, and for prioritizing the individual data packets. This ensures that important or safety-relevant information with increased priority is processed or evaluated by the control system 6 (FIG. 1).

It is expedient if the microcontroller 48 is designed or programmed in order to form a priority order for processing or processing the data packets upon receipt of a plurality of data packets with different priority labels. The system availability or the responsiveness of the controller to various events is thereby considerably improved.

Due to the decentralized placement of several control devices 7 within the conveyor system 1 (FIG. 1), it is either only possible or comparatively cost-effective to implement various sensor systems in the control system 6 or in the control sequences of the conveyor system 1. In particular, it may be expedient if at least one control device 7 has a delivery counter 49 and / or an operating hours counter. As a result, the utilization or operating time of the corresponding conveyor device 3, 4, 5 (FIG. 1) can be detected, whereupon utilization-dependent maintenance or service messages can be generated automatically. Such a conveyor counter 49 is preferably realized by software, but can also be implemented by an additional sensory counter component.

Alternatively or in combination, at least one control device 7 may be connected to at least one vibration sensor 50 arranged on the conveyor members 15 (FIG. 2) and / or on the support frame. As a result, any faults or defects in the mechanical components of the conveyor device 3, 4, 5 can be detected automatically and generate corresponding errors or warning messages. Such service or warning messages can be signaled locally to the control device 7 and / or transmitted via the data network 9 to the material flow computer 10 or the host computer 11 (FIG. 4) or to a globally remote service control center.

The decentralized or distributed control devices 7 within a conveyor system 1 (FIG. 1) also allow a simple integration of noise-sensitive sensors or of at least one acoustic detection device 12, in particular of at least one microphone 51. This acoustic detection device 12 or the at least one Microphone 51 is preferably connected to an input of the control device 7, in particular to an input of the input and output modules 34 or to an input of the central unit 45 and to detect noises in the environment of the respective conveyor device 3, 4, 5 (FIG. 4) , This allows early detection of any damage caused by excessive stress or wear and tear. These sensory states can be evaluated automatically and used for the timely deposition of automatic service or status information.

It may be expedient if the control device 7 comprises at least one digital memory device 52, in particular a fault memory for the storage and logging of operationally hazardous or operationally disturbing states. This functionality enables efficient fault localization or troubleshooting.

The control device 7 of at least one conveyor device 3, 4, 5 (FIG. 1) can also be designed to determine the conveyor-related utilization or conveying load of the conveyor devices 3, 4, 5. The determined data can be logged and / or forwarded by the control device 7. In particular, such data can be sent to the material flow computer 10 and / or the host computer 11 and / or to globally distanced service centers.

It can be expedient if the control device 7 is connected to a storage device 5 52 for depositing a basic software package that is common to all conveyors 3, 4, 5 and to the storage of type-specific or function-specific additional software. As a result, a certain basic configuration of the conveying devices 3, 4, 5 (FIG. 4) is already possible at the factory and system-specific or application-specific adaptations or additions to the basic software are made possible at any time without problems. By a certain basic equipment with operating software, the effort to install a complex conveyor system 1 (Fig. 4) can be reduced in an advantageous manner.

The sensors or actuators described above, wherein the actuator is also an engine start unit or a frequency converter for drive motors, can be connected to the central unit 45 via a field bus system and / or to the input and output modules 34 be connected to the central unit 45:

The embodiments show possible embodiments of the conveyor system 1 and the electrically controllable conveyor device 3, 4, 5, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather also various combinations of the individual embodiments with each other are possible and this possibility of variation due to the doctrine of technical action by objective invention in the skill of those working in this technical field is the expert. 25
