Definitions
- the present invention relates to a labeling machine for labeling containers and a method for establishing a network connection for transmitting security-relevant data between a labeling machine and a labeling unit according to claim 8.
- Labeling machines for containers are known from the prior art which have a number of docking points or docking stations to which labeling units can be connected. Places that are not required are usually provided with a cover so that no opening is left open, into which an operator could accidentally reach. This enables flexible modification and adaptation of labeling machines and spaces that are not required can remain free.
- IP address can be assigned to a labeling unit in order to transmit data to the specific labeling unit.
- this assignment is not completely reliable, so that a transmission of data relevant for the occupational safety of operators or of time-critical data to the labeling units concerned cannot always be ensured.
- the task to be solved is to provide a label animal machine and a method for establishing a network connection with which the safety of an operator can be guaranteed as reliably as possible.
- the labeling machine according to the invention for labeling containers comprises at least one docking station for a labeling unit and a machine control, the docking station comprising at least one network access for establishing a network connection between the machine control and a docked labeling unit, the network connection for transmitting security-relevant data and / or time-critical data is formed, and wherein the network access is connected to a manageable Ethernet network switch of the machine control with a DHCP server, the DHCP server being configured, a labeling unit connected to the network access has a preset IP defined by the DHCP server -Assign address.
- the safety-relevant data are understood here to mean data that are relevant to the safety of an operator and in particular include emergency stop functions for emergencies.
- This also includes data or information that is transferred from the labeling unit or the docking station to the machine control. For example, this includes information or data as to whether certain circuit breakers or protective walls on the labeling unit and / or the docking station and / or the labeling machine are closed. Data or information about whether certain safety devices have been switched on, connections between the labeling unit and the docking station (in particular locking devices that prevent the labeling unit from detaching from the docking station) or grounding of the unit can be understood as this.
- Safety-relevant data can also include information or data on the actuation of release switches, the actuation of which, for example, the operator can confirm that he no longer manually intervenes in potentially dangerous components of the machine (for example between rotating cylinders for transferring and accepting labels).
- the safety-relevant data can in principle also be understood to mean data and / or information which must be obtained before the labeling machine is started up and in particular before the start of operation in production mode. It can also be data or information that must be / must be confirmed before the labeling machine is released for normal production (by the machine controller).
- Safety-relevant data are usually not data that are only relevant for the operation of the labeling unit (amount of labels to be applied, timing of the label supply and the like).
- time-critical data should be understood as data that are relevant for the chronological sequence of processes during the operation of the machine. This includes, for example, timing signals that establish a reference time machine-wide, or control commands that can only ensure correct operation of the machine at a specific time if they are received at the labeling unit.
- it can be understood as (confirmation) signals of the labeling unit or units, which must be sent out by the unit at a specific time and received in the machine control or other device in order to ensure the operation of the machine.
- the DHCP server and the Ethernet network switch can be provided as separate components.
- the DHCP server is integrated in the Ethernet network switch, in particular is arranged in the housing of the Ethernet network switch, or is designed as a hardware component of the Ethernet network switch.
- there is a connection between the DHCP server and the Ethernet network switch whereby the DHCP server can also be part of or integrated in the Ethernet network switch.
- the connection between DHCP server and Ethernet network switch is mentioned below, all embodiments in which the DHCP server is designed as part of the network switch or as integrated therein are also included.
- This labeling machine can ensure that the labeling unit is recognized or assigned to the correct docking station and that safety-relevant data and / or time-critical data can therefore also be correctly transmitted between the machine controller and the labeling unit docked at the specific docking station.
- the labeling machine comprises at least two docking stations and the IP address assigned by the DHCP server to the different docking stations are different from one another.
- the Ethernet network switch can include at least two slots for docking stations.
- the central administration of the network connection for the security-relevant data and / or time-critical data is thus given, which reduces the susceptibility to errors by confusing slots.
- each slot is assigned a unique identifier which uniquely identifies the associated docking station and is different from other identifiers.
- Each slot can have a physical marking, wherein a connection to a connecting line for connecting the slot to a network access of a docking station is only possible if the connecting line has a complementary marking.
- a further physical barrier is hereby realized, through which the confusion of connections for the individual docking stations can be avoided.
- each slot can be assigned an auxiliary pin for transmitting an auxiliary signal, the machine control being designed to determine whether a network connection to a docked labeling unit has been established correctly based on receiving a signal via the first slot and via the auxiliary pin.
- Determining whether a docked labeling unit has correctly established a network connection includes, for example, determining whether the safety-relevant data and / or the time-critical data and non-security-relevant data are transmitted to the same labeling unit, in particular to the intended docking station.
- This embodiment also ensures that a deviating assignment of safety-relevant data and / or time-critical data and non-safety-relevant data and / or non-time-critical data to labeling units is not inadvertently made.
- each network access comprises a further network connection to the machine controller, which is designed to transmit data relevant to the operation of the labeling unit, the machine controller being designed, from a comparison of data that is sent via the first network connection with data that about the second network connection are sent to determine whether the network connection with the manageable Ethernet network switch has been established correctly.
- a comparison as to whether the safety-relevant data and the non-safety-relevant data and / or non-time-critical data are transmitted to the same labeling unit is possible, which can further increase the safety for operators.
- the labeling machine comprising at least one docking station for the labeling unit and a machine control, the docking station comprising at least one network access
- the network connection is designed to transmit the safety-relevant data and / or time-critical data
- the network access with a manageable Ethernet network switch of the machine control with one DHCP server is connected, the DHCP server assigning a labeling unit connected to the network access a preset IP address determined by the DHCP server.
- This method ensures the most reliable establishment of a network connection.
- the labeling machine comprises at least two docking stations and the IP address assigned to the different docking stations by the DHCP server are different from one another.
- IP addresses An accidental, ambiguous assignment of IP addresses can be avoided, which also enables the unique identification of docking stations and labeling units.
- the Ethernet network switch can comprise at least two slots for docking stations and each slot can be assigned a unique identifier, which uniquely identifies the associated docking station and is different from other identifiers.
- Each slot can have a physical marker, and a connection to a connecting line for connecting the slot to a docking station network access is only possible if the connecting line has a complementary marker.
- the physical marking prevents the connections and docking stations from being mixed up, thus ensuring that docking stations and labeling units are clearly assigned.
- an auxiliary pin for transmitting an auxiliary signal can be assigned to each slot, the machine controller determining whether a network connection to a docked labeling unit has been correctly established based on receiving a signal via the first slot and via the auxiliary pin.
- each network access comprises a further network connection with the machine control, via which data relevant for the operation of the labeling unit are transmitted, the machine control being based on a comparison of data sent via the first network connection with data transmitted via the second Network connection is sent, determines whether the network connection with the manageable Ethernet network switch has been established correctly.
- This embodiment ensures that the correct labeling unit is addressed with the security-relevant data and / or time-critical data by checking whether the security-relevant data and / or time-critical data for the specific labeling device and the non-security-relevant data and / or not time-critical data for the specific labeling unit are transmitted to the same addressee, that is to the same labeling unit.
- Figure 1 shows a schematic representation of a labeling machine with a number of
- FIG. 2 shows a schematic representation of the connection of a docking station with the manageable network switch and the machine control.
- FIG. 1 shows a labeling machine 100 in accordance with an embodiment that is compatible with the invention.
- the labeling machine 100 comprises a carousel 101, on which a row of container carriers (not shown here) can be arranged, each of which can accommodate at least one container 130 and can be transported along the periphery of the carousel 101.
- the containers can be fed to the labeling machine via suitable transport devices (not shown here) and removed from the labeling machine (after labeling) by other suitable transport devices.
- suitable transport devices include in particular star conveyors, such as infeed stars and outflow stars for transporting the containers in and out. Devices with grippers for individual or several bottles or conveyor belts or combinations thereof are also conceivable.
- the Transportein directions to and from the labeling machine are shown only schematically in Fig. 1 with 190. Any other conceivable and known embodiment for transporting containers to or from a labeling machine is conceivable and can be used together with the invention. Any known variant of the transport of the container through the labeling machine can also be used.
- the containers can be transported in the container carriers, for example on turntables or in centering devices or in neck handling.
- the labeling units can each be designed as a modular unit and have all the devices needed to hold labels and apply them to containers. These include, in particular, cutting devices and, if necessary, gluing units to cut labels and apply glue. Transfer devices, such as a vacuum cylinder, can also be arranged on the labeling unit in order to apply the cut and / or glued labels to the containers. However, it can alternatively also be provided that one or more devices which are necessary for applying the labels to the containers 130 are not provided on the labeling unit, but rather on or at the docking station.
- a transfer cylinder for transferring the labels to the container for each docking station can be arranged on the labeling machine and thus does not have to be additionally provided on the labeling unit.
- the labeling machine can also be designed as a linear machine.
- the container transport extends over a straight transport path, on which labeling units are also provided via corresponding docking stations, as described in relation to FIG. 1, in order to accommodate labeling units
- not every docking station has to be permanently equipped with a labeling unit.
- a labeling unit for example, when labeling containers of a first type, only a single label may be necessary.
- only one labeling unit 121 is arranged on the periphery.
- two labeling units for example, the labeling animal units 121, 131
- one or more labeling units are provided as a reserve if one or more labeling units fail or no longer have any labels, so that the reserve labeling units can take over the application of labels to the containers until the Stock of labels on the remaining label animal aggregates is replenished.
- the labeling units are modular and can be connected to the labeling machine and in particular the docking stations via suitable connections, in particular data lines 122, 132 and 142. Data relevant to the operation of the labeling units, for example, is transmitted via these data lines.
- labeling units must be assigned to emergency switches.
- electronic connections between the labeling units and the labeling machine or the machine control of the labeling machine in this context it must be ensured that the corresponding safety-relevant functions and / or time-critical functions are also assigned to the respective labeling unit. For example, it must be ensured that when an emergency switch on a labeling unit is actuated, this labeling unit is also deactivated. It must also be ensured that security doors or openings or access areas are protected from operator access before the labeling unit can start operating.
- FIG. 2 shows an example of the connection of the docking stations 102 and 103 to a managed Ethernet network switch 220, which in turn is connected to the machine control 210 (the element 210 represents the accesses for the machine control).
- the machine control can, for example, be integrated into the labeling machine shown in FIG. 1. However, it can also be arranged outside the labeling machine.
- the machine control can be designed as a computer or other suitable device for controlling the labeling machine.
- the manageable Ethernet network switch 220 comprises an access element 221 (with a series of slots or accesses 222, 223), via which at least one network connection between a docking station 102 or 103 and the machine controller 210 can be established , security-relevant data and / or time-critical data can be transmitted via this network connection.
- the access element 221 is shown here separately from the switch 220. However, this only serves to illustrate.
- the access element and the Ethernet network switch can be designed as completely separate components, embodiments are also conceivable in which the access element is integrated in the Ethernet network switch, in particular is arranged in its housing.
- the machine controller can also be connected to the respective docking stations via suitable additional connecting lines 251 and 252.
- This connection can also be realized via a network switch integrated in the machine control and therefore not shown separately here. However, only non-time-critical and non-safety-relevant data is exchanged between the docking station / labeling unit and machine control via this connection.
- the accesses 222 and 223 are correspondingly connected to the manageable Ethernet network switch 220, for example by internal wiring.
- the network accesses are connected to a DHCP server within the Ethernet network switch or to a DHCP server assigned to it.
- the DHCP server assigns a unique IP address to each of the network access points, so that the corresponding access at the docking station 102 or 103 is assigned a defined, preset IP address by the DHCP server.
- This IP address is in turn used for the communication of safety-related data and / or time-critical data with a labeling unit which may be connected to the docking station, so that it is ensured by the machine control and in particular by the Ethernet network switch and the associated DHCP server will that a labeling unit for the transmission of security-relevant data and / or time-critical data can be assigned a known and unique IP address.
- DHCP server it is preferred if only one DHCP server is provided for all docking stations of a labeling machine in the Ethernet network switch 220. This ensures that only this DHCP server manages the IP addresses for the respective docking stations, which can prevent incorrect or unintentional assignment of identical IP addresses to different docking stations for the transmission of security-relevant data and / or time-critical data .
- each access 222 and 223 has an at least optical identifier 242 or 243, which allows the respective access to be assigned to the network access of the docking station of the labeling machine.
- the docking stations are numbered consecutively (from 1, 2, 3, etc.).
- Each access can then, for example, pass on the information to the operator by means of a visual marking that this access is intended for a specific docking station, for example the docking station with the number 1, so that when assembling the labeling machine and in particular when establishing the connection between the network access the docking station with the access to the network switch does not make an unintentional error.
- the connecting line (261 or 262) which enables a connection between the network access and the respective slot, can then have a complementary physical marking, so that only the connecting line, which has a corresponding complementary physical marking (271 or 272), with the respective slot on the Ethernet network switch can be connected.
- the physical marking 281 or 282 on the Ethernet network switch or on the respective access can consist of a specific arrangement of notches or grooves or holes. Only if the connecting line 261 or 262 has corresponding complementary arrangements (such as, for example, a pin shaped according to the hole) on the element which is connected to the slot, can the connection between the slot and the connecting line be established, so that a clear Assignment of the connecting cable from the docking station to the slot of the network switch is guaranteed. This ensures, when assembling the labeling machine, with greater certainty that accidental swapping of slots is avoided.
- electronic means can also be used to ensure the correct connection of the slot with the respective network access of the docking station. It can be provided that, on the one hand, the respective docking station is connected to a slot of the network switch (via lines 261 and 262, for example). On the other hand, a connection of the respective docking station to the actual machine control 210 via another connecting line 251 or 252 (Ethernet connection or the like) can be provided. This line can also require the docking station to be assigned to the machine control as clearly as possible. By comparing the IP addresses or by comparing the received data, the machine controls can then determine whether the connection of the docking station to the machine control and a connection of a docking station to the network switch define the same docking station.
- the machine control can confirm that the connection of the docking station and Network switch and machine control is correct. This can be done, for example, by comparing IP addresses. Alternatively, this can also be done by comparing responses to certain data signals that are output by the machine control and / or the Ethernet network switch.
- the machine controls can stop the operation of the labeling machine and / or issue a warning which warns the operator of the possible faulty connection of the docking station and / or a labeling unit to the labeling machine.
- This information or warning can also contain information about which docking stations or labeling units are possibly incorrectly connected. This makes it much easier for an operator to correct the error.
- an additional pin is assigned to each slot, which pin is connected to the docking station via the access element 221 and also has a unique identifier for the respective slot. If a signal returned via this pin matches the docking station provided for the slot, the machine control system can determine that the connection of the docking station to the slot of the network switch has been made correctly and the operation of the labeling machine can be enabled.
- any labeling unit at a designated docking station and a correct connection of a docking station with the DHCP server for transmitting security-relevant data and / or time-critical data is established.
- all labeling units are assigned the same security number, for example.
- the safety network number of the fieldbus stations of the respective labeling units, via which a connection to the docking station is established can be preset identically. Since this number does not necessarily have to represent a unique identification, it can be set to a constant value for all labeling units during programming.
- the internal circuit and the hardware components used for the respective labeling units are all identical, so that no different identification of the labeling units can be generated here either, which is disadvantageous for the identification of the respective docking station or the information transmitted via it Data could impact.
