    The invention relates to a method of bundling flow rates on a conveyor with a plurality of incoming conveyor segments, at least one coupling to an outgoing conveyor segment to which the incoming conveyor segments are brought together, and a plurality of stopping means for stopping a flow of feed on the incoming conveyor segments. Furthermore, the invention relates to a conveying element for bundling conveying streams, which comprises a plurality of incoming conveying segments, at least one coupling for an outgoing conveying segment, to which the incoming conveying segments are brought together, and a plurality of stopping devices for stopping a conveying flow on the incoming conveyor segments. Finally, the invention also relates to a conveyor with several such Fördertechni¬kelementen, wherein at least one coupling is connected directly or indirectly for an outgoing Förderseg¬ment of a conveyor component with an incoming conveyor segmenteines another conveyor component.
    A method, a conveyor element and a conveyor system of the type mentioned are basically known. In this case, a plurality of conveying streams arriving at a conveyor are, if necessary, stopped and forwarded to one or more output conveying streams in order to direct conveyor objects to one or more destinations in a targeted manner. As a rule, a higher-level control manages a series of picking orders and controls the elements of the conveyor system in such a way that the conveyor objects assigned to a destination (eg a picking workstation) are removed from a warehouse and transported to the named destination, in particular a predetermined order or sequence. To this end, sensors are arranged along the conveying path, which detect the nassiprpnrnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnncnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn In particular, in the case of many destinations to be served and a large variety of objects to be transported, this results in a complex control-technical task, which enlightens the operation and in particular the commissioning of a conveyor system.
    In a simple embodiment of such a control, a conveying object which passes through such a sensor can trigger the release of the conveying flow arriving at a conveying device ("triggering"). However, this simplified method results in only moderate throughput through the conveyor system and therefore only a small number of executed orders per unit time.
    It is therefore an object of the invention to specify an improved method and a improved conveyor element for bundling flow rates. In particular, the complexity of a control for a conveyor system should be reduced or the throughput should be increased by the same.
    The object of the invention is achieved by a method of the type mentioned above, in which a plurality of triggering devices or a conveyor object located downstream of the said incoming conveyor segments and logically linked with an OR link are used for releasing a stopping device or a conveyor object and carrying a stopping device a delivery object waiting for it is released when a waiting conveyed object in a sorting order passes preceding conveyance objects of the associated triggering devices or there is no preceding conveyance object.
    The object of the invention is also achieved with a conveying element of the type mentioned at the outset, comprising a plurality of triggering devices located downstream of said incoming conveying segments and a controller which has a plurality of inputs logically linked with an OR link and the input side with said tripping device and the output side is connected to said stopping means, wherein the controller is adapted to release a stopping device or conveying object waiting thereon if a conveying object preceding the said conveying object in a sorting order passes one of said triggering means or there is no preceding conveying object.
    Finally, the object of the invention is also achieved by a conveying system with several conveying elements of the type mentioned above, wherein at least one coupling for an outgoing conveying segment of one conveying element is directly or indirectly connected to an incoming conveying segment of another conveying element.
    The proposed measures a very simple rule forLeiting objects to be realized, but nevertheless enables high throughput. More specifically, a plurality of triggering devices downstream downstream of said conveying element are OR-linked and used for the release of a stopping device or a conveyed object.
    That is, a conveyance object waiting at the stopping means is forwarded when another expected conveyed object passes one of the OR-linked triggering devices or when there is no preceding conveyance object at all. The latter applies, for example, in principle to the first conveyed object of a sorting order.
    Under a " promotion item " In the context of the invention, it should be understood to mean any device for conveying and / or manipulating conveyed objects, which combines conveying streams and continues them via an outgoing conveyor segment or several such segments. In particular, the mentioned conveying technology element can also be regarded as a node via which delivery flows are conducted. Concrete examples of such conveyor elements are all types of sluices, junctions of secondary conveyor tracks into a main conveyor track, turntables, but also robots for retrieving conveyor objects from storages such as stacker cranes and autonomous conveyor vehicles ("shutters") and vertical conveyors such as Lifts and paternoster. All of these elements can concentrate delivery streams from multiple incoming conveyor segments to one node. In the case of lifts and paternoster flow rates from several levels on a few flow rates (usually lower Ebe¬nen) concentrated. A storage and retrieval unit can be regarded as a conveyor technology element that concentrates flow rates from many storage spaces to (usually) one output flow rate.
    The " promotion segments " In general, they can also be seen as logical conveyor segments and are not necessarily purely physical. For example, a stacker crane may be considered a v-to-w multiplexer, where v indicates the number of storage bins reached by the stacker crane and w indicates the number of objects transported simultaneously by the stacker crane. Although physically only a single storage and retrieval unit is present, it can still be regarded as a logical node, which has incoming conveyor segments and waving conveyor segments.
    Under a " stopping device " In the context of the invention, all elements for stopping a delivery flow are to be understood. Barrier means, for example, can be inserted or pivoted into the delivery stream. However, a stopping device can also be understood to mean conveyor belts, conveyor chains, conveyor rollers and the like which can be stopped (ie not only stored loosely). These funds are usually both for conveying and for stopping of conveyed objects.
    In the context of the invention, it is conceivable that each stopping conveyor segment is assigned a stopping device as well as that only one part of the incoming conveying segments of a conveying device element is assigned one stop device each. In particular, it can be provided that all in one conveying segments is assigned with the exception of one stop device each.
    Under a " trigger " For the purposes of the invention, all sensors and reading devices are to be understood which make it possible to identify a conveyed object. For example, these are barcode readers, RFID readers (Radio Frequency
    Identification) as well as video cameras. However, sensors for measuring a physical property of a conveyed object, such as for example length, weight and the like, can basically serve as a triggering device, in particular if several physical properties are measured which are suitable for identifying a conveyed object. For example, this may be the combination of a specific range of values of an object length, a specific value range of an object weight, and a specific value range of an object color.
    The term " OR link " It is to be understood broadly in the light of the invention and is not limited to physical OR gates nor to the concrete use of ORER programming commands. On the contrary, those implementations which achieve an effect according to an OR operation also fall under this concept, even if this is achieved without the use of physical OR gates or OR programming commands.
    Blurring in the order can be deliberately granted in favor of high throughput. For example, a delivery object n can be released if one of the preceding delivery objects n-1, n-2, n-3 or a further delivery object passes one of the OR-linked trigger devices. As a result, although a permutation within the formed actual sequence and, consequently, a deviation from the desired order sequence is possible, this also reduces the probability of blockages in the conveyor system, and the throughput increases. If necessary, the conveying objects can still pass through a sorting stage before reaching the destination in order to achieve an exact actual sequence. By presorting, however, this sorting stage can be kept small and therefore requires only little installation space.
    Advantageous embodiments and developments of the invention will become apparent in the following from the dependent claims and from the description in conjunction with the figures. It is expedient if the stopping device or the conveying object waiting for it is released when a conveying object which immediately precedes the conveying object in a sorting order passes through one of the linked triggering devices. This makes it possible to form an exact actual sorting order, since a conveyed object n is only released when the directly or directly preceding conveyed object n-1 passes through the OR-linked triggering device. It is also favorable if a stopping device or a delivery object waiting for it is released when all conveying objects preceding the waiting conveying object in a sorting sequence have passed one of the linked triggering devices. This makes it even better possible to form a close actual sorting order. An additional sorting is then no longer necessary. For example, a list can be guided on the conveyor element, in which all the conveyor objects are listed, which are to be promoted to predetermined destinations. Those conveyor objects that have passed one of the OR-linked triggering devices are marked accordingly in the list. For example, a flag can be set for this purpose. In this way, it can be checked if a stopping device is to be released or not.
    In general, conveyor elements with different release strategies can also be used within a conveyor system. For example, at the same time conveyor technology elements can be used, which release a conveyor object when one of the preceding conveyor objects n-1 or n-2 passes the triggering devices, when the conveyor object n-1 passes the triggering devices or when all preceding conveyor objects have passed the triggering devices. In this way, critical points of a conveyor system can be defused in that there the sorting criteria are loosened with regard to an improved throughput. Optionally, the default for releasing a conveyor object during operation can also be adapted dynamically, for example, by a higher-level controller.
    It is particularly favorable if the signal of a triggering device arranged directly in an outgoing conveyor segment is also used for the release of the stopping device or of the conveyor object waiting for it. In this way, a conveyed object is conveyed as quickly as possible via the conveying element. As a result, the throughput on the conveyor system is further increased overall.
    In a further advantageous variant of the method, a plurality of conveyed objects have the same ordinal number in the sorting order. In this way, it is possible to form a plurality of groups of conveying objects arranged in a sorting order within which the conveying objects can however be arranged in an unordered manner. That is, the conveyed objects have a not necessarily unique order number. For example, the sort order may include a plurality of order items numbered 3. These Förderobjek¬te be arranged by the presented method after the group 2 but before the group 4. Within the group 3, however, the arrangement of the conveyed objects is arbitrary.
    In a further advantageous variant of the method for forming a sorting order for a destination to be supplied or several such orders for a plurality of destinations to be served in a conveyor system with a plurality of conveyor technology of the type mentioned, the at least one coupling for an offgoing conveyor segment of the one conveyor element are directly or indirectly connected to an incoming conveying segment of another conveying element, and several of the triggering devices logically linked with an OR linkage are in each case downstream of another downstream conveying device element of the type mentioned. In this way, a plurality of release devices are used for different nodes of a plurality of networked or chained conveyor technology elements for the release of a conveyed object. As a result, the throughput on the conveyor system can be increased even further. &Quot; direct " means in the above context that the Ankopp¬lung is connected for an outgoing conveyor segment of a conveyor technology without the interposition of other elements with an incoming conveyor segment ei¬εe another conveyor element, "indirectly". the contrary. In particular, among the other intermediate elements are manipulators which divide or fan out the flow, for example branches and the like.
    It is particularly advantageous if the process steps associated with the conveying elements are carried out independently of the method steps of the other conveying elements with respect to the control of the stopping devices-up to the message of a conveying object passing a triggering device. As a result, the communication and therefore the expenditure for communication lines between conveyor elements can be kept low.
    It is also particularly advantageous if a program logic is constructed identically in terms of the control of the stop devices in all conveyor elements, or if the method steps with regard to the control of the stop devices in all conveyor elements are carried out identically. In this way, the effort for the production or programming of the control for a conveyor system can be kept low overall, since it is composed of several identical modules. The effort for a possible troubleshooting can be kept small thereby. In addition, a method for operating a conveyor system of the type mentioned above with an upstream warehouse with storage spaces for conveyor objects is also advantageous, the conveyor element being designed as an outlier robot for the warehouse. As already mentioned, such robots, which are designed, for example, as a control panel, autonomous conveyor vehicles ("shuttle"), lift or paternoster, can concentrate delivery streams from several incoming conveyor segments onto one node. For example, a shelf control unit can be considered as a v-to-w multiplexer, where v indicates the number of storage bins provided by the storage rack and w the number of objects transported simultaneously by the storage and retrieval unit.
    Also advantageous is a method for operating a conveyor system of the type mentioned above with an upstream warehouse with storage areas for conveyor objects, in which conveyor objects are sorted out in terms of the destinations and in terms of a sort order for a destination to be served. This means that first conveyor objects for the destination with the lowest position are stored in an order, then the conveyor objects with the second lowest position, etc. In addition, the conveyor objects for a specific destination are also outsourced in an orderly manner. If, in the warehouse from which the material is removed by means of a conveyor element, for example the conveyor objects 3 and 5 of the destination A and the conveyor objects 1 and 7 of the destination B, the conveyor objects are stored in the order A3, A5, B1, B7 , In this example, it is assumed that the conveyor-missing objects in the order (i.e., A1, A2, A4, B2, B3, etc.) are located in other warehouses that are out-sourced from other conveyor devices. In this way, on the whole, a high degree of order of the conveying streams present on the conveyor system can be achieved.
    However, it is also advantageous if conveyed objects are sorted out in terms of a sorting sequence for a destination to be supplied, but are cha¬cated out of the store in a chaotic or not necessarily ordered manner with regard to the goals. Based on the example mentioned above, this means that the conveying objects can also be stored in the sequence B1, A3, A5, B7 or, for example, also in the order B1, A3, B7, A5 Throughput can be increased during the removal, for example, if during transport outsourcing transport paths are minimized. It is also favorable if at least two conveyor elements are directly or indirectly annularly connected to each other, or if at least one partial flow is annular over the said conveyor elements. In other words, feedback is provided in the network of connected conveyor technology elements. For this purpose, at least one outgoing conveyor segment of at least one conveyor element is connected to at least one incoming conveyor segment of at least one other upstream conveyor element. In this way, the degree of order of the conveyed conveyed objects can be increased in several passes, or, respectively, gaps can be filled in the order step by step.
    At this point, it is noted that the terms " downstream " and " upstream " can be used synonymously with respect to an annular partial flow. However, the release devices ORed in a conveyor mechanism for releasing a stop means do not necessarily include release means disposed in the ring only, but may also comprise trigger means located outside the ring and thus clearly downstream. In addition, it is favorable if the delivery flow is fanned out again after the coupling for the outgoing conveyor segment. In this way, the outgoing flow can be directed in different areas of a conveyor system or to different destinations. It is also conceivable that the outgoing delivery flow is fed back to a plurality of incoming delivery segments of upstream delivery elements. For example, the conveyed objects can be fed back in a predetermined sequence or chaotically to several incoming conveyor segments of upstream conveyor modules so as to gradually increase the degree of order within the conveyor flow or also to fill in gaps in the sequence.
    In a further advantageous variant of the method, the releases per unit time are monitored by a higher-level control, and the stopping device is enabled on which the delivery object with the lowest order number waits if the thresholds for the releases per unit time are exceeded. This avoids that there is a long-term blockade on the conveyor by unfavorable arrangement of the objects to be conveyed. Instead of releasing the delivery object with the lowest order number, a release can also be chaotic or random. Advantageously, this variant of the method with an annular feedback in the Flow combined to successively increase the degree of order of conveyed objects transported on the conveyor. It is also advantageous if the threshold value is adapted according to the number of objects located on the conveyor system. This means that the threshold value is increased as the number of transported objects increases and vice versa. This avoids that a sinking number of clearances, which is due to a small number of transported objects conveyed, is misinterpreted as a blockade. For example, such a state can occur when a picking order is started or, for example, even if it is almost finished. In both cases, there are comparatively few objects on the conveyor system because they are still in the warehouse for the majority or are already loaded in shipping containers. It is also advantageous if a pausing of the removal of the conveyor objects at a destination is taken into account. Especially with manual picking, there are inevitable interruptions to the workflow, for example, when a worker takes his break or goes to the bathroom. In this case, there may also be a decrease in releases per unit time, which is not due to a blockade.
    It should be noted at this point that the variants disclosed for the method according to the invention and the advantages resulting therefrom relate mutatis mutandis to the conveying element according to the invention or the conveyor system according to the invention and vice versa.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description apply mutatis mutandis to the same parts with the same reference numerals. same component names can be transferred. Also, the location information chosen in the description, such as up, down, laterally, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis in a position change. Furthermore, individual features or combinations of features from the illustrated and described different exemplary embodiments may also represent separate, inventive or inventive solutions.
    Fig. 1 shows a first example of a conveying element Ka for bundling conveying streams. The conveyor element Ka comprises two incoming conveyor segments 1a, 1b, a coupling 2 for an outgoing conveyor segment 3, to which the incoming conveyor segments 1a, 1b are brought together, and several stop devices 4a, 4b for stopping a conveyor flow to the ingoing conveyor Conveyor segments 1a, 1b. Because of the mentioned combination, the conveying element Ka can also be regarded as a node. In addition, the conveyor element Ka comprises a controller 5 which has a plurality of inputs 6 logically linked to an ORER link and which is connected on the output side to the said stop devices 4a, 4b. On the input side, the controller 5 is connected or connected to a plurality of (in this case three) triggering devices A downstream of the mentioned conveying segments 1a, 1b. These are shown in dashed lines in FIG. 1, since they are usually located on a conveyor (not shown in FIG. 1). The controller 5 is set up to release a stop device 4a, 4b or a conveyor object waiting for it when a conveyed object advancing in a sorting order passes one of the said triggering device A or there is no preceding conveyed object.
    In the example shown in FIG. 1, only two incoming Förderseg¬mente 1a, 1b are provided. Of course, it is also conceivable that more than two incoming conveying segments 1a, 1b are provided. Likewise, it is conceivable that deviating from the representation of FIG. 1, more than one coupling 2 and more than one outgoing conveyor segment 3 are provided. Also conceivable is one of three different numbers of inputs 6 or tripping devices A.
    It is also noted at this point that FIG. 1 is a purely symbolic representation of the conveyor element Ka. For example, the stopping devices 4a, 4b are shown as valves. Of course, this is not to be understood as limiting, but as stopping means 4a, 4b, all elements for stopping a flow can be used. By way of example, these can be understood to mean barriers or barriers which can be inserted or pivoted into the delivery stream. However, a stopping device 4a, 4b can also be understood to mean conveyor belts, conveyor chains, conveyor rollers and the like which can be stopped. Since these conveying means generally serve to convey as well as to stop conveying objects, in this case a sharp distinction between the stopping means 4a, 4b and the incoming conveying segments 1a, 1b is difficult or impossible. The incoming conveyor segment 1a, 1b therefore fulfills a double function in this case.
    It is also conceivable that - notwithstanding the representation in FIG. 1 - not all incoming conveyor segments 1 a, 1 b are each assigned a stopping device 4 a, 4 b. For example, the stopping device 4b can be omitted, so that a conveying object arriving on the conveying segment 1b is always forwarded or prioritized.
    Finally, it is also noted that the OR operation does not necessarily have to be implemented as a dedicated logic gate, but can also be embodied, for example, in the form of a software algorithm that is executed in a processor.
    Fig. 2 now shows a further embodiment of a conveyor element Kb, which is very similar to the conveyor element Ka shown in Fig. 1. In contrast to this, however, each stopping device 4a, 4b is assigned its own OR link. In this way, it is possible in principle to implement the activation of the stopping devices 4a, 4b by means of two parallel (and possibly also independently of each other) running algorithms. It would also be conceivable to use different triggering devices A for controlling the stopping devices 4a, 4b.
    FIG. 3 shows a further example of a conveyor element Kc, which should in particular clarify that the controller 5 is not limited to the OR link, but can also assume other tasks. In FIG. 3, the controller 5 is connected to sensors and / or reading devices 7a, 7b, by means of which the conveyor objects arriving at the conveyor segments 1a, 1b can be identified and their rank or position determined in a sorting sequence , In addition, it is indicated with the output line 8 that the aforementioned detection of an incoming conveyor object can also be reported to upstream conveyor elements Kc or else to a higher-level control. That is, a reading device 7a, 7b can also function as a triggering device A for upstream conveying technology elements Kc.
    FIGS. 4 to 6 are intended to illustrate, by means of a simple example, how the release of a stopping device 4a, 4b or of a waiting conveyor object can take place. For this purpose, a list is kept in the conveyor element Ka..Kc, in which all conveyor objects are listed, which are to be conveyed to predetermined Zie¬ len. For the sake of simplicity, a sorting sequence of six conveyor objects is assumed, which should arrive in ascending order at a single destination.
    According to the algorithm running in the conveying element Ka..Kc, in this example a stopping device 4a, 4b or the conveying object waiting for it should be released when a conveying object immediately preceding the conveying object in a sorting sequence passes one of the linked triggering devices A. , That is, a conveyed object n is released only when the immediately preceding conveyed object n-1 passes one of the OR-linked triggering device A, whereby it is basically possible to form an accurate actual sorting order at the target.
    In Fig. 4, a first time or state is shown, to or at the first stop means 4a, the delivery object number 2 and the second stop means 4b the delivery object number 6 waits. None of the other conveyor objects number 1,3, 4 or 5 has yet passed one of the OR-linked trigger devices A. These are therefore marked with an "x" in the table.
    At a second point in time, which is shown in FIG. 5, the conveying object number 1 has passed one of the OR-linked triggering devices A and is marked with a check in the table. Therefore, the immediately following conveying object number 2, which is at the stopping device 4a waiting, released.
    Accordingly, another time point is shown in FIG. 6, in which the conveying object number 2 has left the area of the conveying element Ka..Kc and the conveying object number 4 has advanced. The conveyor element number 2 is accordingly marked as expected in the list as at the downstream tripping devices A, that is with an "x". Of course, this can also be marked from the beginning in the list with an "x".
    A further release would take place in the example shown by the conveying object number 3 (namely for the conveying object number 4) or by the conveying object number 5 (namely for the conveying object number 6).
    As can be seen from Figs. 4 to 6, a method of bundling conveying streams is carried out on a conveying element Ka..Kc, in which a plurality of triggering devices A downstream of the incoming conveying segments 1a, 1b and logically linked with an ORing device 4 are released 4b or of a conveyor object, wherein a stopping device 4a, 4b or a conveyor object waiting for it is released when a conveying object preceding the waiting conveyor object in a sorting sequence passes one of the linked triggering devices A or there is no preceding conveying object. The latter would, for example, apply to the subsidized object number 1. The proposed measures implement a very simple rule for guiding conveyed objects while still allowing high throughput.
    In the above-mentioned example, a conveyed object n is released only when the immediately preceding conveyed object n-1 passes one of the OR-linked triggering devices A. But this is by no means the only conceivable possibility. Rather, it is also conceivable that a certain blurring in favor of a high throughput is deliberately allowed in the sorting order. For example, a conveyed object n can be released if one of the preceding conveyed objects n-1, n-2, n-3 or an even further preceding conveyed object passes one of the OR-linked triggering devices A. For example, it may be allowed that the delivery object number 6 is also released by the transport objects number 3 and 4. As a result, although a vertau¬schung within the formed actual order and concomitantly a deviation from the desired order is possible, but also decreases the probability of blockages in a conveyor system and it increases the Durch¬satz.
    It is also conceivable for a stopping device 4a, 4b or a waiting conveying object to be released when all conveying objects preceding the waiting conveying object have passed one of the linked triggering devices A in a sorting order. This makes it even better possible to form an exact actual sorting order. An additional sorting is then no longer necessary. In the above example, this means that the delivery object number 6 is only released when all other delivery objects number 1 to 5 have passed one of the OR-linked release devices A.
    A further measure for increasing the throughput is also the use of the signal of a release device A releasing device 4a, 4b arranged directly in an outgoing conveyor segment 3, as shown in the example shown in FIG. If the delivery objects number 3 and 5 were waiting at the stopping devices 4a, 4b, then the release of the delivery object number 2 would entail the immediate release of the subsidized object number3. In this way, a conveyed object is conveyed as quickly as possible via the conveyor element and the throughput on the conveyor system is increased.
    Notwithstanding the example shown in FIGS. 4 to 6, it is also possible for a plurality of conveyed objects to have the same ordinal number in the sorting sequence. That is, it would be possible for there to be several # 3 convey objects. In this way it is possible to form a plurality of groups of conveying objects arranged in a sorting order within which the conveying objects can however be arranged in an unordered manner. The conveyor objects number 3 become by the presented method after the conveyed object
    Number 2 but arranged in front of the subsidized object number 4. However, the concrete ranking of the objects number 3 is indefinite. Such a procedure is useful, for example, if the objects to be pumped are the same as those of item 3 (for example, three identical drinks bottles). However, this loosening of the sorting, which does not affect the final result, can contribute to reducing the risk of blockages on a conveyor system and to increasing the throughput.
    Generally, under a " promotion item " Each device for conveying and / or manipulating conveyed objects is understood, which combines conveying streams and continues them via an outgoing conveyor segment or several such segments. For example, for Einschleuser, junctions of Nebenförderbahnen in a main conveyor track, turntables this basie¬rend on the figures 1 to 3 directly. Conveyor elements, which merge För¬ currents, but may for example also be formed by robots for the removal of conveyed objects from a warehouse.
    7 shows an exemplary arrangement with a bearing 9 with several storage spaces L and a storage and retrieval unit 10, which has a run on rails 11 carriage 12 with a vertically movable on a mast 13 Hubplatt¬ form 14. The function of a storage and retrieval device 10 is known per se and therefore need not be explained in detail at this point.
    FIG. 8 shows a schematic front view of the bearing 9, from which a possible numbering of the storage spaces L1... LV follows.
    FIG. 9 now shows a logical or symbolic representation of the storage and retrieval device 10 shown in FIG. 7. From FIG. 9 it can be seen that a number of incoming conveyor segments 2 corresponding to the number v of the storage spaces L1 .. Lv is concentrated on an outgoing conveyor segment 3. The concentration of the delivery flow is thereby formed by the lifting platform 14, which in this example can receive only one delivery object in each case. The shelf control device 10 can therefore be considered as a v-to-1 multiplexer.
    It is also conceivable that the lifting platform 14 can accommodate several objects simultaneously. A logical representation of a storage and retrieval unit 10 with a lifting platform 14 accommodating two conveyor objects is shown in FIG. 10. Each of the parking spaces forms a logical node K1, K2. In the concrete example, it is assumed that the conveyed objects are transported to the right. This means that the object located at the node K1 can only be transported away when the object transported via the node K2 has left the lifting platform 14. For this reason, the output of the node K1 is passed as an input to the node K2. Of course, other arrangements are conceivable in which the conveyor objects can leave the Hubplatt¬ form 14 at the same time and the nodes K1, K2 are therefore not linked in the manner shown darge. In general, a storage and retrieval unit can be regarded as a v-to-w multiplexer, where v indicates the number of storage spaces L1.Lv reached by the storage and retrieval unit 10 and w the number of objects simultaneously transported by the storage and retrieval unit 10 or the storage spaces present on the lifting platform14. In particular, FIGS. 9 and 10 also show that the conveyor segments can generally also be seen as logical conveyor segments and are not necessarily to be considered purely physically. In the case of a v-to-1 storage and retrieval unit, there is always only one incoming delivery segment 1a, 1b at a time.
    FIG. 11 shows a further exemplary arrangement, comprising a bearing 9, a lift 15 arranged just above the bearing 9, and a plurality of autonomous conveying vehicles 16 ("shuttles") operating on the individual bearing planes. Such a shutter 16 removes a conveyor object 17 from a storage space L and transports it to the elevator 15. This takes over the object 17 and transports it to a further conveying path (not shown).
    The logical structure resulting from FIG. 12 is shown in FIG. 13. In this case, each shuttle 16 forms a node K1... K4, on each of which the storage spaces L1. .L8 of a storage row are guided. The conveyor segments 3 departing from the nodes K1... K4 are in turn routed to the node K5, which represents the lift 15.
    Fig. 13 shows another arrangement with a bearing 9 and shuttles 16, which is very similar to the arrangement shown in Fig. 11. In contrast, but instead of the lift 15, a paternoster 18 is provided.
    Fig. 14 again shows a logical representation of the arrangement shown in Fig. 13. Assuming that the paternoster 18 can transport the conveyed objects 17 in a circle, this is shown in FIG. 14 as a loop, wherein the nodes K5..K8 the transfer points in the individual levels of the Lagergers 9 and the nodes K9 and K10 form two withdrawal paths which (physically) can be arranged side by side or even one above the other, for example.
    Finally, FIG. 15 shows a somewhat more complex example of a conveyor system. As already in FIGS. 9, 10, 12 and 14, several conveyor elements Ka..Kc are coupled to one another such that at least one coupling 2 for an outgoing conveyor segment 3 of the one Conveying element Ka..Kc is directly or indirectly connected to an incoming conveyor segment 1a, 1b of another conveyor element Ka..Kc. In this case, several of the triggering devices A, which are logically linked with an OR linkage, are in each case stored downstream of a downstream conveying device Ka..Kc of the type mentioned. As in FIGS. 9, 10, 12 and 14, the conveying technology elements or nodes K1... K34 are only shown in simplified form. &Quot; direct " means in the above context that the coupling 2 is connected for an ab¬hendes conveyor segment 3 of a conveyor component Ka..Kc without Zwi¬schenschaltung other elements with an incoming conveyor segment 1a, 1beines other conveyor component Ka..Kc. For example, in Fig. 15, nodes K5 and K16 are concerned. &Quot; Indirect " means that other elements are interposed, in particular branches and the like. For example, the connection of the nodes K16 and K24 is indirect, since K19 and K22 are interposed and act as fanning.
    Concretely, the arrangement shown in FIG. 15 comprises a bearing 9, a plurality of autonomously operating shuttles 16 and lifts 15 connected to the bearings 9. In this example, the bearing 9 three rows of shelves or Re¬ galgassen, each shelf row 32 Lagerbetätzte L, which are arranged in four Ebe¬nen to eight places. Accordingly, in the first row of shelves, the shuttles 16 represented by the nodes K1, K4, the shuttles 16 represented by the nodes K6..K9 in the second row of shelves, and the shuttles 16 represented by the nodes K11..K14 in the third row of shelves are represented by the nodes K5, K10 and K15.
    The lifts 15 are followed by a horizontal loop 19, in which the nodes K16..K21 are arranged. The arrow indicates the direction of conveyance. Via the nodes K19 and K20, conveyor objects are transferred from the loop 19 into a network 20 which has several nodes K22..K34 which are networked with one another. The network 20 is adjoined by an optional sorting area 21 and to this a commis sion area 22. In the picking area 22 there are three destinations 23a..23c to be supplied, for example workstations where conveyor objects 17 are loaded automatically or manually into shipping containers or on pallets.
    In the example shown in FIG. 15, only one target 23a is preceded by a sorting stage 24. It would also be conceivable, however, for all targets 23a, 23c to be preceded by one sorting stage 24 or else none. Finally, in the example shown in FIG. 15, a plurality of tripping devices A1..A22 are provided. For example, each shuttle 16 is assigned a triggering device A1..A4, A6..A9 andA11 ..14 on the receiving platform. Each lift 15 is assigned a triggering device A5, A10 and A15 on the lifting platform.
    It is expressly pointed out that the arrangement of the tripping devices A1..A22 is merely exemplary in order to illustrate the mode of operation of the conveyor system illustrated in FIG. 15 and, of course, can also be done differently. In particular, it is pointed out that in the network 20 of the better Darstellbar- sake half no triggering devices are shown. Of course, in a real system 20 triggering devices can also be provided in the network at any point. It should also be pointed out that the networking of nodes K1... K34 with triggering devices A1... A34 in FIG. 15 is also not shown explicitly in a real implementation of the conveyor system is self-evident.
    For example, the tripping devices A5 and A16 can be connected to the inputs 6 of the conveyor element K1. For example, the triggering device K24 can be connected to the triggering device K21. The conveying element K24 can be connected to tripping devices, not shown, in the network 20 and so on. Physically, the connection of the tripping devices A1 ..A22 with the nodes K1 ..K34 can be wired or wireless. For example, the tripping devices A1 ..A22 can be connected to the nodes K1 ..K34 via a bus system. The connection of a tripping device A1 ..A22 with a node K1 ..K34 then takes place, for example, by storing or marking in a memory of the node K1 ..K34 the address of the tripping device A1 the OR link is to be used. In the same Wei¬se the connection can be made in a wireless network.
    In the example shown in FIG. 15, a plurality of conveying elements / nodes K1... K34 are connected directly or indirectly in an annular manner. Accordingly, at least one partial flow is conducted in an annular manner over the said conveyor technology elements / nodes K1... K34. In other words, feedback is provided. For example, node K21 is connected to node K18, node K32 to node K22, node K34 to node K23, and node K33 to node K21. In this way, the degree of order of the conveyed conveyed objects 17 can be increased in several passes, or gaps in the sequence can be filled step by step. The terms " downstream " and " upstream " may be used synonymously with respect to such an annular sub-stream. Of course, the feedbacks shown in FIG. 15 are purely exemplary and serve to better illustrate the possibilities. Of course, other annular connections are equally conceivable.
    FIG. 15 also shows some fanning out of the delivery flow, for example at nodes K22..K31. In general, fanning out can serve to direct an outgoing delivery flow into different regions of a delivery system or to different destinations 23a, 23c. It can be a
    Node K22..K31 with several outgoing conveyor segments 3 mentally also in a node K22..K31 with only one outgoing conveyor segment 3 and nach¬gelagerten node with several outgoing conveyor segments 3 be divided. It is favorable if the method steps associated with the conveyor elements K1... K34 are independent of each conveyor element K1... K34 with regard to the control of the stop devices 4a, 4b, up to the message of a conveyor object 17 passing a trigger device A1.. be carried out by the Verfahrensschrit¬ten the other conveyor elements K1..K34. As a result, the communication and thus the outlay for communication lines between the conveyor elements K1..K34 can be kept low.
    In this context, it is also advantageous if a program logic with regard to the control of the stopping devices 4a, 4b in all conveying elements K1 ..K34 is constructed identically, or if the procedural steps with regard to the control of the stopping devices 4a, 4b in all conveying elements K1..K34 are carried out identically. In this way, the expense for the production or programming of the control for a conveyor system can be kept low overall, since this is made up of several identical modules. The effort for aneventuellen troubleshooting can be kept small.
    In general, conveyor elements K1 ..K34 with different release strategy can also be used within a conveyor system. For example, the conveyor elements K1..K15 can be set up to release a conveyor object n if one of the preceding conveyor objects n-1 or -2 passes one of the OR-linked triggering devices A1 ..A22, whereas the other conveyor elements K16..K34 can be set up, for example, to release a conveyed object n only when the preceding conveyed object n-1 passes one of the OR-linked triggering devices A1 ..A22. In this way, critical points of a conveyor system can be mitigated when the sorting criteria for improved throughput are relaxed. Optionally, the specifications for releasing a conveyed object 17 during operation can also be adapted dynamically, for example, by a superordinate control.
    In order to form a predetermined sorting order, it is also advantageous if conveyed objects 17 are sorted out in an ordered manner with respect to the targets 23a, 23c and with respect to a sorting order for a destination 23a, 23c to be supplied. This means that firstly conveyed objects 17 for the target 23a..23c with the lowest position in an order, then the conveyor objects 17 with the second lowest position, etc. In addition, the conveyor objects for a specific destination 23a..23c are also sorted out. Are in the Re¬galreihe the bearing 9, from which is ausa¬gert with the conveyor elements K1, .K4, for example, the conveyor objects number 3 and 5 of the target 23a and the conveyor objects 1 and 7 of the target 23b, then the funding objects in the order a3, a5, b1, b7 outsourced. In this example, it is assumed that the delivery objects 17 missing in the order (eg, a1, a2, a4, b2, b3, etc.) are located in other rows of shelves that are different from other conveyor elements K6..K9, K11. K14 be outsourced. In this way, overall a high degree of order of the conveying streams present on the conveyor system can be achieved.
    Alternatively, it would also be conceivable for the conveyed objects 17 to be arranged with respect to a sorting order for a destination 23a, 23c to be supplied, but to be relocated from the store 9 in a chaotic or disordered manner with respect to the targets 23a, 23c. In relation to the above-mentioned example, this means that the conveyed objects 17 can also be removed, for example, in the order b1, a3, a5, b7 or, for example, also in the order b1, a3, b7, a5. Due to the unordered removal at the destination level, the throughput in the case of outsourcing can be increased, for example if, during the removal, transport paths of the conveyor elements K1... K15 are minimized.
    Optionally, the conveyor objects 17 may pass through a sorting stage 24 before reaching a destination 23a, 23c in order to achieve an exact actual sequence, as is provided in FIG. 15 for the destination 23a. By Vorsor¬ tion, however, this sorting stage 24 can be kept small and therefore requires only little space.
    In order to detect blockages on the conveyor system or to remedy them, it can also be provided in an advantageous embodiment that the releases of the nodes K1 ..K34 are monitored by a higher-level control unit per unit of time, and those stoppers 4a, 4b are released, which the Delivery object 17 with the lowest order number waits if the releases per unit time fall below a threshold value.
    For example, if the value of the shares per unit time decreases from a relatively constant value (e.g., 50 shares per minute) to a very low value, o, even zero, it can be assumed that there is a blockage on the conveyor. Through higher level intervention, this blockage can be resolved again. Instead of releasing the delivery object 17 with the lowest order number, a release can also take place accidentally, for example.
    It is also advantageous if the threshold value is adapted in accordance with the number of objects 17 located on the conveyor system. That is, the threshold value is increased as the number of transported objects 17 increases and vice versa. This avoids that a decreasing number of releases, which is due to a small number of transported objects 17 transported, is misinterpreted as a blockage.
    For example, such a state may occur when a picking order is started or, for example, even when it is almost finished. In both cases, there are comparatively few objects 17 on the conveyor because they are still in the majority still in the warehouse 9 or already loaded in shipping containers. It is also advantageous if a pause in the removal of the conveyed objects 17 at a destination 23a, 23c is taken into account. In particular, during manual picking, there are inevitable interruptions of the work process, for example, when a worker takes his break or searches the toilet. In this case, there may also be a decrease in releases per unit time, which is not due to a blockade.
    In this context, it is also expedient if the outsourcing of conveying objects 17 from the bearing 9 is adjusted in accordance with the removal of the conveying objects 17 at the target 23 a, 23 c. This means that the number of conveyed objects 17 removed from the storage 9 per unit of time is reduced when the number of conveyed objects 17 removed per unit of time at the destination 23a, .23c drops and vice versa.
