Definitions
- the present invention relates to a method of operating a gluing system for gluing blanks for the manufacture and / or packaging of cigarettes or other smokable articles, in which the blanks are conveyed along glueing lines of the gluing system.
- the invention further relates to a corresponding gluing system that can be operated with this method.
- DE 10 2008 027 259 proposes to regulate the glue valves depending on different operating parameters in such a way that the sizes of the glue portions produced by the glue valves on the blanks can be kept at a constant value during the entire operation.
- gluing systems can not or only to a limited extent be used to implement such a method.
- a central control device takes over the control of all glue valves.
- unidirectional signal lines to each glue valve extend from the central control device according to the number of valves to be controlled. Return lines from the valves to the controller are not provided.
- Such controls are static, relatively slow and inflexible.
- a superordinate master controller for controlling and / or regulating the glue valves of the gluing system, the individual, the glue valves associated, the master controller downstream controllers - which are each connected to the parent master controller via a suitable data connection - respectively values of at least one control and / or control parameters transmitted, by means of which the respective downstream controller controls and / or regulates the glue valve assigned to it.
- control and / or regulation tasks on the one hand at least one higher-order master controller and on the other hand downstream controllers, which are assigned to the individual glue valves.
- the respective subordinate controller takes over, in particular, time-critical control and / or regulation tasks as well as possibly amplifier functions for amplifying control signals.
- the parameters by means of which he performs control tasks are managed by the master controller and, if appropriate, calculated using suitable algorithms or selected from a database which can be accessed by the master controller.
- each subordinate controller controls and / or regulates only one glue valve of the gluing system.
- the appropriate number of downstream controllers can be used.
- the control devices have individual Control cards, each with outputs for multiple valves. If fewer or more valves have to be actuated than there are outputs, certain outputs of the control cards accordingly disadvantageously remain unused.
- sensors can be connected to the downstream controllers, detect the measured values of at least one measured variable, that the downstream controller transmit these measurements to the master controller and that the master controller for the relevant, connected to the respective controller Leimventil dependent on these measured values calculates the control and / or control parameters and / or selects from a database associated with the master controller. Subsequently, the calculated and / or selected parameter is transmitted to the respective downstream controller.
- the temperature of the glue supplied to the respective glue valve or of the glue present in the respective glue valve can be detected.
- the pressure can be measured downstream of a feed pump, under which the glue is supplied to the respective glue valve.
- parameters can be detected which characterize the movements of a closure member moving within the respective glue valve in the glue.
- the one or more corresponding sensors of the glue valves each measure these at least one measured variable.
- the respective downstream controllers then transmit the measured values to the higher-level master controller via their named data connections. This manages the measured values and evaluates them.
- the master controller can then transmit new, adapted values of the at least one control and / or regulating parameter to the glue valves, for example.
- the evaluation can also reveal that the value of the at least one control and / or control parameter, on the basis of which the respective downstream controller controls the glue valve connected to it controls and / or regulates, does not need to be adjusted. In this case, the corresponding value of the control and / or control parameter that the downstream controller can access is naturally not changed.
- a control and / or regulating parameter by means of which the downstream controllers control / regulate the respectively connected glue valve can be, for example, the intensity and / or duration of the electrical current applied to an electromagnet of the respective glue valve, through which the glue valve is opened a closure member of the respective glue valve is moved during operation of the gluing system.
- Glue valves with such solenoid for moving closure members are, for example irr ⁇ DE 10 2008 027 259, the contents of which is hereby fully incorporated.
- the gluing system has a modular structure. More specifically, the downstream controllers are each designed as individual modules which can be connected to the master controller and / or to at least one further downstream controller via suitable contact connection means, in particular via contact plugs and / or contact tongues.
- the contact connection means are respectively arranged at the ends of signal lines for transmitting electrical (or possibly electromagnetic) signals which run on or in the individual controllers.
- the contact connection means interconnect these signal lines of the individual controllers.
- the signal lines are lines of a suitable data bus system, such as a CAN bus system.
- the housing of a first downstream controller in the state connecting the signal lines at least partially applied to the housing of the master controller.
- the housing of a second downstream controller in the connected state at least partially applied to the housing of the first downstream controller, the housing of a third subordinate controller to the housing of the second, etc.
- the glueing system can be correspondingly expanded by a further downstream controller for controlling / regulating the glue valve that has been added.
- This modular design allows in a simple manner to supplement the system by more glue valves or vice versa to remove one or more glue valves from the system.
- 1 is a schematic representation of the glue system according to the invention for the gluing of blanks in the production / packaging of cigarettes
- Fig. 3 is a current-time diagram, the current flows through the electromagnet different, integrable in the Beleimungssystem

- a gluing system 10 in particular with the aid of glue valves 11 of the gluing system 10, areas or sections of blanks from which the corresponding packing is formed are provided with glue portions selectively emerging from the glue valves 11.
- the blanks below the glue valves 11, namely below lockable glue valve openings 12 are conveyed past these. Details on this are described in DE 10 2008 027 259, to which reference has already been made above.
- the gluing system 10 must be operated in such a way that the individual glue portions are positioned on the blank at desired times, in desired quantities and / or in desired patterns.
- the latter has a master controller 13, to which individual downstream controllers 15 are connected by means of suitable signal or data lines 14.
- the data lines 14 are each part of a bus system, in the present case a so-called CAN bus system. This bus system allows bidirectional data communication between the master controller 13 and the individual downstream controllers 15.
- the downstream controllers 15 are connected to a power supply 16 via suitable power lines 17.
- an electromagnet with corresponding coil drive 19 is located inside the glue valve 11 and serves to move a closing member which is at least partially surrounded by the electromagnet or coil of the electromagnet. By a restoring force, the closure member is held in the currentless state of the electromagnet in a conventional manner within a valve seat.
- a sensor for detecting a relevant for the proper operation of the glue valves 11 measured value is arranged in each case via a control line 18b.
- a temperature sensor 20 extending into the valve interior. With this, the temperature of the glue located in operation within the glue valve 11 can be detected as a measured variable.
- controller 15 ends in each case one of a line controller 21 outgoing control line 22nd
- the distance control 21 are transmitted to one of its inputs signals of a rotary encoder 23.
- the rotary encoder 21 detects rotations of the central machine axis of a packaging machine, not shown, known per se for packaging cigarettes.
- the rotary encoder 23 is connected by means of a signal line 24 to the track controller 21.
- Both the master controller 13 and the track controller 21 are connected via corresponding signal or data lines 25, 26 to the central machine control 27 of the packaging machine.
- the line 25, which connects the master controller 13 to the machine controller 27, formed as Ethemet- connection can be exchanged over the bidirectional data.
- the signal line 26 between the path controller 21 and the machine controller 27 is also bidirectional in the present case.
- the control of the gluing system 10 is carried out as follows:
- the path controller 21 accesses the data transmission line 26 to a database associated with the machine control 27.
- glue dot patterns are deposited.
- the path controller 21 sends corresponding control signals to the downstream controller 15.
- downstream controllers 15 are each notified or specify times at which the glue valves 11 have to be opened.
- the opening itself takes place by applying the appropriate electromagnets with suitable electrical currents.
- each subordinate controller 15 has an amplifier unit which sufficiently amplifies the small control signal currents originating from the line controller 21 in order to be able to effect suitable opening movements of the closure members of the glue valves with the aid of the electromagnets.
- the magnitude of the current that flows through the electromagnet during an opening cycle is controlled by the downstream controllers 15 based on control parameters stored in the controllers 15 or in their associated memories or databases. In operation, these parameters can each be adapted as a function of the glue temperature measured by the sensors 20 in each case.
- the viscosity of glue is temperature-dependent.
- the glue in a particular glue valve 11 may have such a low viscosity at a particularly high temperature deviating from predetermined setpoints that a readjustment of the glue valve 11 becomes necessary.
- first of all the temperature values which the respective temperature sensor 20 measures are transmitted from the respective controller 15 to the master controller 13.
- the master controller 13 evaluates for each Glue valve 11, the measured temperatures based on predetermined setpoints or other criteria.
- the respective glue valve 11 must remain open for a correspondingly shorter time than is the case at a lower glue temperature in order to be able to guarantee a predetermined glue serving size in spite of the high temperature.
- the master controller 13 sends a suitably adapted control parameter, which represents the opening time of the glue valve to be adapted, to the respective downstream controller 15.
- the previously stored value for the opening duration in the controller 15 is overwritten.
- the downstream controller 15 accordingly adjusts the opening time of the same in the control of the glue valve 11.
- the strength of the so-called opening current flowing through the electromagnet can be adjusted and / or the strength of the so-called holding current.
- the values for the opening current or the holding current are also each stored as parameters in the downstream controllers 15 and dynamically adaptable in the manner described above by the master controller 13 as a function of the measured glue temperature.
- the parameters required for the production of a particular type of packaging or for gluing the blanks of this type of packaging become Production start over the Ethernet connection 25 from the central machine controller 27 to the master controller 13 transmitted.
- the corresponding parameters are stored in suitable databases of the machine control.
- the glue dot patterns are stored there, which can be accessed by the pattern controller 21.
- the master controller 13 can either calculate the new values of the control parameters to be transmitted to the downstream controllers 15 using suitable algorithms and / or select from databases in which, for example, the relevant control and / or or control parameters are stored.
- each glue valve 11 can be individually controlled independently of the other glue valves 11.
- the glue valves 11, namely the electromagnets installed therein, have characteristic current flow curves 28a-28c.
- the current flowing through the coil of the electromagnet in operation current is detected according to the invention as a parameter.
- the current curve 28b shows a curve deviating from the current curve 28a of a valve whose specifications do not match the gluing system 10.
- a non-matching glue valve e.g. an electromagnet with mismatched specifications be installed.
- the master controller 13 now compares the actual current values or curves of the respective glue valves with stored desired current curves. Upon detection of Deviations of the master controller 13 detects that a non-matching glue valve of other specification is installed.
- the current curve 28c represents the current profile of a matching but defective glue valve. This, too, is recognized by the master controller 13 by appropriate comparison with desired profiles.
- the detected current profiles can also be evaluated on the basis of other predetermined criteria in order to detect any errors or deviating specifications.
- the master controller 13 initiates a signal representing a glue valve error and / or a signal representing the absence of a predetermined feature of the analyzed glue valve.
- a signal representing a glue valve error and / or a signal representing the absence of a predetermined feature of the analyzed glue valve As a result, an operator can be informed of this via an acoustic, optical or other signal.
- the master controller 13 depending on the analysis of the current waveforms, selects a specific control / regulation parameter set from a database and transmits it to the dependent controllers 15.
- downstream controllers 15a-e are implemented as individual modules which are each connected to the master controller 13 and / or to at least one further downstream controller 15a-e via contact connection means, namely electrically conductive contact tongues 29.
- the master controller 13 and each downstream controller 15a-e have for this purpose on their front and / or rear sides of their respective housing in each case a corresponding contact tongue 29.
- the contact tongues 29 are each attached, relative to the individual controllers 13, 15a-e, to ends of corresponding signal lines or data lines which run inside the housing of the controllers 13, 15a-e.
- a first subordinate controller 15a is first connected to the master controller 13.
- the master controller 13 and the first subordinate controller 15a are first placed against each other and locked together by not shown locking means in a mutually aligned position.
- the second integrated into the system 10 controller 15b is located with the front of his case again on the back of the already on the
- the lines in the controllers 13, 15a-e are configured and interconnected in such a way that they form a total of a bus system, namely a so-called CAN bus.
- Each controller 15a-e controls precisely one glue valve 11.
