    Proverbs 1 and 9.
    In addition to the processing of workpieces in industrial production systems using automated production machines and their operation by industrial robots, it is also common practice to provide parts for the workpieces and to remove them using so-called driverless transport systems (AGVs). These are internal, floor-bound conveyor systems with automatically controlled vehicles whose primary task is to transport materials. Such an AGV includes one or more driverless transport vehicles (AGV), a control system, devices for location determination and storage detection, for data transmission as well as infrastructure and peripheral devices. As driverless transport vehicles, floor-bound conveyors with a drive, which are automatically controlled and guided without contact, are provided. With such AGVs, material can be transported by pulling or carrying conveyed goods with active or passive load handling equipment. The driverless transport vehicles can be designed, for example, similar to a fork lift truck or a forklift. To ensure the safety of the workforce, the AGVs must also be equipped with person recognition systems. On the other hand, the production cells of such production systems are secured by protective barriers, for example by a protective fence. Such a protective partition which limits the production
    cell, prevents people in the vicinity from
    N2018 / 30600-AT-00
    System are disturbed.
    The object of the invention is therefore to create a manufacturing device by means of which personal safety can be ensured with greater reliability and in the event of disruptions in the manufacturing process running in the manufacturing cell, which could be caused by the automated delivery of workpieces or their removal, avoided if possible
    can be.
    This object is achieved by a manufacturing device with a manufacturing cell for processing workpieces, with a laterally circumferential protective partition forming a boundary of the manufacturing cell, a lock being formed in the protective partition for carrying out a loading process of the workpieces. In this case, a first light barrier arrangement with a first transmitter and with a first receiver assigned to the first transmitter is formed at an opening of the lock, and a driverless conveyor with a load-handling device is provided for conveying the workpieces. To carry out the loading process, a second light barrier arrangement and a third light barrier arrangement are formed between the conveying means and the lock, so that the load handling means and the workpieces from the
    second light barrier arrangement and from the third light barrier arrangement
    N2018 / 30600-AT-00
    usable safety device is possible.
    It is also advantageous that while the loading process is being carried out, an area connected to a parking zone of the lock for the workpieces is laterally limited by the conveying means, the second light barrier arrangement and the third light barrier arrangement, since this results in the transfer of workpieces into the production cell during the process into or out of the protection zone of the production cell and the protection zone of the conveyor are connected to a single, coherent protection zone and monitored
    can be.
    According to a further development it is provided that the conveying means comprises a control device, the control device being designed to activate and deactivate the second light barrier arrangement and / or the third light barrier arrangement as required, under program control. This has the advantage that components of the lock that are required to carry out a loading process can remain inactive until a conveyor is at the
    Lock arrives and a loading process starts.
    The lock advantageously comprises a control device, the control device being designed to position the first light barrier arrangement in front of the
    Lock to be activated and deactivated as required, program-controlled.
    The further development of the production device, according to which the control device of the conveyor and the control device of the lock are designed to jointly monitor the second light barrier arrangement and the third light barrier arrangement in a program-controlled manner, has the advantage that the loading process is carried out locally, i.e. independently of the higher-level control device of the production cell and also independently of the central control device
    the entire manufacturing device, organized and carried out.
    N2018 / 30600-AT-00
    is consolidated, includes.
    In a further development, the manufacturing device is designed in such a way that the second light barrier arrangement is designed to transmit a message from the control device of the conveyor to the control device of the lock, and that the third light barrier arrangement is designed to transmit a message from the control device of the lock to the control device of the conveyor is. This has the advantage that direct communication between the conveyor and the lock of the production cell is possible without the need to exchange messages with the higher-level control device of the production cell or with the central control device of the entire production cell.
    must take place.
    The design of the manufacturing device is also advantageous, according to which the conveying means comprises a detector for forming a monitoring area, the monitoring area protruding laterally beyond a common spatial extent of the load-bearing means and the workpieces. This means that collisions between the conveying means while it is in motion on the operating
    land and during the loading process can be avoided.
    The object of the invention is also achieved independently by a method for loading workpieces with a driverless conveyor and a manufacturing cell for processing the workpieces, a lock being formed in a laterally circumferential protective partition of the manufacturing cell, and an opening of the lock by a first light barrier arrangement is secured against unauthorized access with a first transmitter and with a first receiver assigned to the first transmitter, and wherein the driverless conveyor is a
    Includes load handling means and is controlled by a control device. At
    N2018 / 30600-AT-00
    Lock can be done in an automated manner.
    In an advantageous further development of the method, it is provided that when the control device of the conveying means registers an interruption of the second light barrier arrangement or the third light barrier arrangement, the conveying means is stopped. This can lead to collisions and damage to parts, but above all to injuries to operators.
    in the vicinity can be prevented.
    It is also advantageous that if the control device of the conveying means registers an interruption of the second light barrier arrangement or the third light barrier arrangement, a detector of the conveying means is activated, with the detector providing a monitoring area that shows a common spatial extension of the load handling device and the workpieces in the lateral direction Direction dominates, is formed. This allows an automated control of the monitoring area with regard to the presence of an obstructing object or a person and thus also an automatic continuation of an interrupted loading process when the obstacle is removed again
    has been.
    N2018 / 30600-AT-00
    penetrates.
    In the method of the control device of the conveying means and of the control device of the lock, the second light barrier arrangement and / or the third light barrier arrangement are advantageously used for the direct transmission of messages between the conveying means and the lock. Thus, the entire communication or the entire data and information exchange between a conveyor and the lock can be independent
    be done by the higher-level control devices.
    For a better understanding of the invention, it will be based on the following

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference symbols or the same component designations, whereby the disclosures contained in the entire description can be transferred accordingly to the same parts with the same reference symbols or the same component names. The location details chosen in the description, such as above, below, to the side, etc., refer to the figure immediately described and shown and these position
    in the event of a change in position, information must be transferred to the new position accordingly.
    Fig. 1 shows a manufacturing device 1 with a manufacturing cell 2 and a
    Funding 3.
    The manufacturing device 1 is shown in FIG. 1 in a plan view from above. A so-called floor-bound driverless transport vehicle (AGV), which has its own drive (not shown) and can thus be automatically controlled and guided without contact, is provided as the conveying means 3. The conveying means 3 is designed with a load receiving means 4 for the transport of material. According to this exemplary embodiment, the load-bearing means 4 is designed in the form of a fork lift truck with two prongs or forks 5. With the aid of the forks 5, the load handling device 4 can pick up and transport pallets 7 loaded with workpieces 6. The production cell 2 has a protective partition 8 in the form of a laterally circumferential boundary. According to this exemplary embodiment, the protective partition 8 is formed by a protective fence. In the
    N2018 / 30600-AT-00
    be formed for example by a bending press.
    In the laterally circumferential protective partition 8, a door 12 provided with a safety device 11 is provided. This ensures that only authorized and authorized operators can enter the production cell 2. On the other hand, the protective partition 8 of the production cell 2 has a door or a lock 13 which is used to transfer the workpiece into and out of the production cell 2. The lock 13 also has a safety device with which unauthorized access to the production cell 2 is to be prevented. According to this exemplary embodiment, a light barrier arrangement 14 is provided as the safety device of the lock 13. The light barrier arrangement 14 of the lock 13 is in turn connected to a control device 15 by means of which its operating states can be monitored and controlled. The control device 15 of the lock 13 is also connected to a control device 16 of the production cell 2. In the event that a person or any object intrudes into the monitored area of the light barrier arrangement 14 or crosses it, this is detected by the control device 15 of the lock 13 and communicated to the control device 16 of the production cell 2. The control device 16 of the production cell 2 can then interrupt the operation of the processing device 9 and the handling device 10.
    or, if necessary, initiate other safety measures.
    The conveyor 3 also has an independent control device 17 which enables the program-controlled, automatic operation of the conveyor 3. This includes the control of the travel movements, the lifting and setting down of the pallets 7 with the workpieces 6, the determination of the location and navigation on the company premises as well as the communication with a central one
    Control device 18 of production device 1. It can therefore be exchanged
    N2018 / 30600-AT-00
    directly monitor the journey on the company premises.
    FIG. 2 shows a detail of the manufacturing device 1 according to FIG. 1. As can be seen better from the arrangement of parts of the manufacturing device 1 shown enlarged in FIG. 2, the conveying means 3 has a protective field or a monitoring area 19. This monitoring area 19 is implemented by a detector 20 belonging to the conveying means 3. The detector 20 can be implemented, for example, by what is known as a laser scanner, with the aid of which objects can be detected in the protective field. The detector 20 of the conveying means 3 is arranged in such a way that its monitoring area 19 protrudes laterally beyond the spatial extent of the forks 5 and the pallet 7 with the workpieces 6. The monitoring area 19 remains unchanged in its relative arrangement with respect to the conveying means 3, as is the case with the detector 20 which determines it. If the conveyor 3 comes too close to an obstructive object during its journey and this object is recognized by the detector 20 as being in the monitoring area 19, the control device 17 of the conveyor 3 can stop the conveyor 3 or cause an evasive maneuver of the conveyor 3 so that a collision with the obstructing object or with a person can be prevented. Consequently, with it
    property damage or personal injury can also be avoided.
    The scanner or detector 20 for generating the monitoring area 19 moving with the conveying means 3 can additionally also be changeable in its spatial extent. For example, the monitoring area 19 can be used if a higher travel speed of the conveying means is selected
    3 can be enlarged in order to ensure a greater safety distance.
    3 to 7 show different sections or further phases of the method for the delivery of workpieces 6 to the production cell 2 with the aid of the conveyor 3. The situation shown in FIG. 2 or the corresponding operating
    The state of the manufacturing device 1 corresponds to the arrival of the conveyor 3
    N2018 / 30600-AT-00
    at the lock 13 of the production cell 2. The control device 17 of the conveyor 3 - prior to the situation shown - received a transport order for the delivery of workpieces 6 to the production cell 2 from the control device 18 of the production device 1. In the situation shown, access to the lock 13 is still through the light barrier arrangement.
    14 blocked.
    This light barrier arrangement 14 in front of the lock 13 comprises, in a manner known per se, a first transmitter 21 and a first receiver 22. These are each arranged on opposite sides of the door or the lock 13. The transmitter 21 and the receiver 22 of the light barrier arrangement 14 are also aligned with one another in such a way that a light beam generated by the transmitter 21 can be built up or maintained between the transmitter 21 and the receiver 22. In which the transmitter 21 and the receiver 22 are connected to the control device 15 of the lock 13, the
    Control device 15 an interruption of the light barrier 14 can be recognized.
    According to the invention, the manufacturing device 1 or the lock 13 is the
    Production cell 2 and the conveying means 3 with further transmitters 23, 24 or receivers 25, 26 for the temporary construction of light barrier arrangements 27, 28
    formed (Fig. 4).
    In FIG. 3, the conveyor 3 is shown in a starting position for the loading process of the pallet 7 with the workpieces 6 into a parking zone 29 of the lock 13. In this case, an entry direction 30 of the load suspension means 4 is aligned with one another in a direction of passage 31 of the lock 13. Accordingly, the transmitter 23 and the receiver 25 of the second light barrier arrangement 27 on the one hand and the transmitter 24 and the receiver 26 of the third light barrier arrangement 28 on the other hand are positioned or arranged on the conveyor 3 or in the lock 13. That is to say, the two transmitters 23, 24 of the conveying means 3 are arranged on the latter laterally with respect to the entry direction 30 of the load-bearing means 4. On the other hand, the two recipients are also
    25, 26 of the lock 13 arranged laterally with respect to the passage direction 31,
    N2018 / 30600-AT-00
    so that when the two light barrier arrangements 27, 28 are switched on or activated, they laterally limit the load handling device 4 with the workpieces 6 or with the pallet 7. It is preferably provided that the two light barrier arrangements 27, 28 are essentially parallel to one another
    are aligned.
    In an activated state of the two light barrier arrangements 27, 28, a U-shaped lateral boundary is formed by them together with the conveyor 3. As a result, a coherent spatial area, in the interior of which both the parking zone 29 of the lock 13 and the load handling device 4 of the conveyor 3 are located, is secured or enclosed on the side (FIGS. 4, 5, 6). The two side light barrier arrangements 27,
    28 thus serve as a temporarily deployable safety device.
    After the conveyor 3 has assumed its starting position in front of the lock 13 of the production cell 2 (according to FIG. 3) to carry out the loading process, which can be determined by an integrated device for determining the location of the control device 17 of the conveyor 3, the control device 17 will both Light barrier arrangements 27, 28 activated. For this purpose, the two transmitters 23, 24 are switched on so that light beams fall on the respective receivers 25, 26 and are detected by them. The activation of the two light barrier arrangements 27, 28 can consequently be registered by the control device 15 of the lock 13, whereupon the first light barrier arrangement 14 in front of the lock 13 can be switched off by the control device 15 of the lock 13 (FIGS. 3, 4). This corresponds to a transfer or a change in the security function from the first light barrier arrangement 14 in front of the lock 13 to the two lateral light barrier assemblies 27, 28. This means at the same time an expansion of the spatial area to be protected towards the common area of the parking zone 29 of the lock 13 and Load handling means 4 of the conveying means 3. In the further course of the loading process the lateral light barrier arrangements 27, 28 then serve to monitor or to secure the expanded, common loading
    Reichs (load handling device 4 and parking zone 29).
    N2018 / 30600-AT-00
    The subsequent phase of the loading process - after activation of the light barrier arrangement 27, 28 - now consists in the conveying means 3 entering the lock 13 with its load handling means 4 (FIG. 5). By lowering the forks 5 of the load suspension means 4, the conveying means 3 can then set the pallet 7 with the workpieces 6 in the parking zone 29 and then
    move out of the lock 13 again (Fig. 6).
    As soon as the conveyor 3 has reached its original starting position in front of the lock 13 again, the control device 17 of the conveyor 3 deactivates or switches off the two light barrier arrangements 27, 28 (FIGS. 6, 7). This can be registered by the control device 15 of the lock 13 on the basis of the absence of signals from the two receivers 25, 26 of the lock 13, whereupon the control device 15 detects the first photoelectric barrier.
    rdnung 14 switches on again in front of the lock 13.
    For the described loading process, it is also provided that when the conveyor 3 has reached its starting position in front of the lock 13 and has stopped there, the scanner or the detector 20 for the monitoring area 19 of the conveyor 3 is deactivated (FIGS. 3, 4 ). On the other hand, after completion of the loading process, before the conveyor 3 leaves the starting position in front of the lock 13 again (FIG. 6), the detector 20 is switched on again
    and the monitoring area 19 is activated again (FIG. 7).
    During the period in which the safety function is exercised by the two lateral light barrier arrangements 27, 28 (FIGS. 4, 5, 6), the two control devices 15, 17 of the lock 13 and the conveying means 3 interrupt the light beams of the two light barrier arrangements 27, 28 interpreted as the penetration or exceeding of the corresponding limits by an object or person and appropriate security measures are initiated. This includes, for example, that the conveyor 3 is automatically stopped by the control device 17. On the other hand, in such a case, the control device 15 of the lock 13 can control the first light barrier arrangement 14 in front of the lock 13 (by switching on the first transmitter 21
    and the first receiver 22) are activated again.
    N2018 / 30600-AT-00
    For such a case where an object or a person penetrates the area monitored by the two light barrier arrangements 27, 28, it is preferably also provided that after such an interruption of one of the light barrier arrangements 27, 28 is detected, the monitoring area 19 of the conveyor 3 is switched on by switching on the detector 20 is activated again. The interrupted loading process can then only be continued again by the control device 15 of the production cell 2 when it can be determined from the signals or data received from the detector 20 of the monitoring area 19 of the conveyor 3 that the monitoring area 19 is free of obstacles again. The measures required for this can be carried out in an automatic manner, with the cooperation of the control device 17 of the conveying means 3
    and the control device 15 of the lock 13.
    8 shows the situation of an interruption of a loading process of the conveying means 3 at the lock 13 of the production cell 2. According to the illustration, the lateral light barrier arrangement 28 is interrupted by a person 32 in that his body covers the light beam emitted by the transmitter 24. As a result, the receiver 26 of the light barrier arrangements 28 cannot detect the light beam, which is what the control device 15 of the lock 13
    can be registered as the occurrence of a fault.
    The control device 15 of the lock 13 can then generate a message or message that is transmitted via the control device 16 of the production cell 2 to the central control device 18 of the production device. From the central control device 18 of the manufacturing device 1, the control device 17 of the conveyor 3 then receives the notification of the interruption of the lateral light barrier arrangement 28 and the conveyor 3 is stopped in response to this. As a further reaction to the notification of the interruption of the light barrier arrangement 28, the detector 20 for the monitoring area 19 of the conveying means 3 is switched on. The travel movement of the conveying means 3 is only then continued again by its control device 17.
    set when the monitoring of the monitoring area 19 by the detector
    N2018 / 30600-AT-00
    gate 20 has shown that person 32 is no longer in the monitoring
    rich 19 of the funding 3 stops. The resumption of the travel movement of the conveyor 3 also requires that the receivers 25, 26 of the lock 13 receive the corresponding light beams from the transmitters 23, 24 of the conveyor 3 again (corresponds to the situation as shown in FIG. 4).
    9 shows a detail of an alternative embodiment of the manufacturing device 1. Again, the same reference numerals or component designations are used for the same parts as in the preceding FIGS. 1 to 8. To avoid unnecessary repetition, please refer to the detailed description in the
    previous figure. Reference is made or referred.
    In the production device 1 according to this exemplary embodiment, the two lateral light barrier arrangements 27, 28 formed between the conveying means 3 and the production cell 2 are provided by an alternative arrangement of FIG
    Senders and receivers realized.
    The left light barrier arrangement 27 (left when looking from the conveyor 3 to the lock 13 of the production cell 2) is, as in the embodiment according to FIGS. 2 to 8, by the transmitter 23 on the conveyor 3 and the receiver 25 on the lock 13 formed. To form the right light barrier arrangement 28, a transmitter 33 is provided on the lock 13 and a receiver 34 is provided on the conveyor 3. The conveying means 3 now has the transmitter 23 on the left and the receiver 34 on the right. While the control device 15 of the lock 13 with the left-hand
    th receiver 25 and the transmitter 33 located on the right is connected.
    In addition, it is provided in the manufacturing device 1 according to this embodiment that the two lateral light barrier arrangements 27, 28 can also be used for the direct transmission of messages between the conveying means 3 and the lock 13. For this purpose, the control device 17 of the conveying means 3 or the transmitter 23 are designed to allow the light
    beam of the left light barrier arrangement 27 modulates a coded signal
    N2018 / 30600-AT-00
    can be, which on the other hand can be received and decoded by the receiver 25 or the control device 15 of the lock 13. In a manner analogous to this, the control device 15 of the lock 13 with the transmitter 33 is also designed to transmit a message to the receiver 34 or the control device 17 of the conveying means 3 via the light beam of the right light beam arrangement 28. In this way, direct communication between the conveyor 3 and the lock 13 of the production cell 2 is possible without the need to exchange messages with the higher-level control device 16 of the production cell 2 or with the central control device 18 of the entire production cell.
    transmission device 1 must take place.
    The method for delivering workpieces 6 to the production cell 2 with the aid of the conveyor 3 according to this embodiment variant allows operating conditions to be checked using additional criteria, this being possible in direct communication between the conveyor 3 and the lock 13 of the production cell 2. In its basic state, the control device 15 of the lock 13 will keep its light barrier arrangement 14 activated and thus monitor the access to the lock 13. In addition, the control device 15 only needs to monitor the state of the receiver 25, so that in the event of the arrival of a conveying means 3 between it and the lock 13 of the production cell 2
    communication can take place.
    A conveyor 3 arriving at the lock 13 of the production cell 2 for the delivery of workpieces 6 will initially assume a starting position for the loading process in front of the lock 13, in which the entry direction 30 of the load handling device 4 or the conveyor 3 is aligned with the passage direction 31 of the lock 13 is aligned. As soon as the conveyor 3 has assumed this starting position for the loading process, the control device 17 of the conveyor 3 will switch it on by activating the transmitter 23 on the left side of the side light barrier arrangement 27 and thus - and by detecting the light beam from the receiver 25 - a connection to the lock 13 or produce their control device 15. In response, the control device may
    Device 15 of the lock 13, the right light beam arrangement 28 by activating
    N2018 / 30600-AT-00
    of the transmitter 33, with which in turn a light beam is directed onto the receiver 34 on the conveyor 3. The detection of the light beam at the receiver 34 of the conveying means 3 finally gives its control device 17 the information that the charging process can now actually be carried out. This mutual determination of readiness for the loading process is also a prerequisite for the light barrier arrangement 14 to be deactivated by the control device 15 of the lock 13 and, on the other hand, the detector 20 for the monitoring area 19 by the control device 17 of the conveyor 3. Finally, the control device 17, the conveyor 3 for
    Entrance into the lock 13 set in motion.
    During the further course of the loading process, the two lateral light barrier assemblies 27, 28 monitor an extended, coherent spatial area that includes both the load handling device 4 with the fork 5 and the pallet 7 with the workpieces 6 and the parking zone 29 in the lock 13 . An interruption of one of the two light beams of the lateral light barrier arrangements 27, 28 is recognized by the control devices 15, 17 of the conveying means 3 and the lock 13 as the occurrence of a malfunction and can be detected directly by the two control devices 15, 17.
    When communicating with each other, emergency measures are initiated
    10 shows a situation of a disruption or interruption of the loading process of the conveyor 3 at the lock 13 of the production cell 2. In the situation shown, the body of a person 32 has come so close to the extended monitoring area that the light beam of the right-hand light beam arrangement 28, between the transmitter 33 of the lock 13 and the receiver 34 of the conveyor 3, is interrupted. The control device 17 of the conveyor 3 thus registers a lack of a signal from the receiver 34 and the conveyor 3 is stopped. At the same time, the control device 17 can generate a corresponding message that is transmitted to the control device 15 of the lock 13 via the left light barrier arrangement 27. In addition to stopping the conveyor 3, the control device 15 of the lock 13 as
    further protective measure switching on the light barrier arrangement again
    N2018 / 30600-AT-00
    14 in front of the lock 13 and from the control device 17 of the conveyor 3, the switching on of the detector 20 to activate the monitoring area 19.
    be taken.
    Otherwise, the resumption or continuation of the loading process after such an incident can also take place in an automated manner. If the control device 17 of the conveying means 3 determines that the person 32 or some other interfering object is no longer in the monitoring area 19, this fact can also be communicated to the control device 15 of the lock 13. As a further consequence - after deactivation of the detector 20 of the conveying means 3 and switching off the light barrier arrangement 14 in front of the lock 13 again - the conveying means 3 can start up again
    set and the loading process continued.
    As a particularly strict security measure, it is provided in particular that during the entire duration, i.e. From the occurrence of the disturbance until it is established that there is no more disturbing object or person, the monitoring area 19 is monitored by the detector 20 and the access to the lock 13 is monitored by the light barrier arrangement 14. Only then may an automatically generated
    controlled restart of the loading process can be carried out.
