Definitions
- the present invention relates to a device for applying a flowable medium to a substrate, in particular hotmelt adhesive, with an application valve which has a closure element which, in an open position, releases a metering opening of the application valve, so that the flowable medium can flow through the metering opening in the direction of the substrate can flow, with the closure element being movable by an electromagnet of the application valve from a closed position, in which it closes the metering opening, into the open position, and with a main control unit connected to the application valve, in particular a PLC (programmable logic controller), which is used for the controlled voltage supply of the electromagnet, in particular periodically, provides electrical output voltage signals that move the closure member into the open position and hold it there.
- PLC programmable logic controller
- Application devices with electromagnetically operated application valves are widely known and are used, for example, in the tobacco industry in order to apply portions of hotmelt adhesive to pack parts of cigarette packs or the like that are to be glued together, such as folding flaps of pack blanks.
- the electromagnets of the application valves are each periodically transmitted a voltage signal with a constant amplitude over the signal duration, which entails a constant current consumption in the electromagnets and correspondingly a constant force with which the closing element first moves into the open position and then there is held.
- the so-called holding current which is required for holding the closure member that is already in the open position, could be smaller than the opening current previously required, which causes the actual opening movement.
- these (simple) controls therefore accept a higher current consumption of the electromagnets than is actually necessary.
- the application device mentioned at the outset is characterized according to the invention in that a modification unit is arranged between the main control unit and the application valve (in particular arranged between the main control unit and the application valve in an electrical series arrangement of main control unit, modification unit and application valve), which is designed in such a way that it Receives output voltage signals from the main control unit, modifies them and forwards them in a modified form to the electromagnet.
- a modification unit is arranged between the main control unit and the application valve (in particular arranged between the main control unit and the application valve in an electrical series arrangement of main control unit, modification unit and application valve), which is designed in such a way that it Receives output voltage signals from the main control unit, modifies them and forwards them in a modified form to the electromagnet.
- a power cable from the main control unit is connected to it, to which the modification unit is routed, and that in order to transmit the modified output voltage signals to the electromagnet of the application valve a power cable is routed from the modification unit to the application valve to which it is or will be connected. It can of course be provided that the cable routed to the application valve is connected directly to the electromagnet or indirectly via corresponding electrical connecting power lines or connecting power cables assigned to the application valve.
- the modification unit can in this way be easily arranged outside of it at a distance from it.
- the modification unit either only new cables would have to be laid from the main control to the modification unit or to the application valve, or alternatively the existing cable between the main control and application valve would have to be cut and the modification unit integrated into it .
- the modification unit away from the main controller, in particular outside of a housing or the housing of the main controller.
- the main control unit can be designed in such a way that for each movement of the closure member from the closed position to the open position, it generates an output voltage signal with an in particular constant voltage amplitude with an amount greater than zero, which is sufficient to move the closure member from the closed position to the to move the open position.
- the modification unit can also be such be designed such that it modifies each of these output voltage signals during a modification period, namely either during the entire signal duration of the respective output voltage signal or during a partial period of the signal duration of the respective output voltage signal, in such a way that the mean value of the voltage amplitude of the respective output voltage signal related to the modification period is smaller than this would be the case if the respective output voltage signal were not modified. This can be achieved, for example, by suitable clocking of the respective output voltage signal during the modification period.
- the modification unit can also be designed in such a way that the voltage amplitude of the respective output voltage signal has a constant value over the entire signal duration without modification of the modification unit, and that the clocking of the respective output voltage signal in the modification period reduces the effective value of the voltage amplitude in this modification period than 50% of the value of the aforesaid constant voltage amplitude of the output voltage signal.
- the modification unit can be designed in such a way that the voltage amplitude of the respective output voltage signal has a constant value of 24 V over the entire signal duration without modification of the modification unit, and that the respective output voltage signal is modified during the modification period in such a way that the effective value of the voltage amplitude in the Modification period is less than 12 V, preferably less than 10 V.
- the respective modification period As far as the respective modification period is concerned, during which the respective output voltage signal is modified, it can in each case follow a period in which no modification of the respective output voltage signal takes place and in which the voltage amplitude of the output voltage signal forwarded to the electromagnet corresponds to the voltage amplitude of the respective unmodified, corresponds to the output voltage signal generated by the main controller.
- the respective output voltage signal can cause an opening current in the electromagnet in the aforementioned period in which no modification takes place, as a result of which the closure element is transferred from the closed position to the open position, and in the subsequent modification period a holding current that is smaller than the opening current.
- the modification unit can expediently have an electronic circuit for carrying out the modification of the output voltage signals, in particular a driver.
- the modification unit can have an analysis device, designed in particular as a microcontroller, for analyzing the respective output voltage signals and/or a device for detecting operating states of the application valve, in particular the electromagnet of the application valve, or errors, such as a breakage, in the connection from the modification unit to the application valve routed power cable.
- an analysis device designed in particular as a microcontroller, for analyzing the respective output voltage signals and/or a device for detecting operating states of the application valve, in particular the electromagnet of the application valve, or errors, such as a breakage, in the connection from the modification unit to the application valve routed power cable.
- the modification unit can also have a display for displaying information and/or a transmission unit for transmitting information, in particular wirelessly, to a remote receiving unit, in particular information about the operating states of the application valve or about faults in the cable.
- the modification unit can have a preferably electronic memory in which information can be stored, preferably by the microcontroller and/or from which information can be read, preferably by the microcontroller, particularly preferably information generated or provided by the microcontroller about operating states of the application valve or about faults in the power cable routed from the main control unit to the modification unit or in the power cable routed from the modification unit to the application valve power cord.
- the main control unit As far as the main control unit is concerned, it can be designed in such a way that it applies an additional extra-low voltage to the output voltage signals in order to supply the modification unit with energy.
- FIG. 1 an oblique view (principle representation) of an application device according to the invention with an electromagnetically operated application valve for applying portions of liquid medium to a substrate, with a main controller for generating output voltage signals for the application valve and with a modification unit for modifying the output voltage signals,
- FIG. 2 shows a side view of a section of the device from FIG. 1 ,
- Fig. 3 shows a diagram modified with the modification unit
- FIG. 4 is a time-associated diagram showing the time course of the electric current I (ordinate) which is set in an electromagnet of the application valve of the application device from FIG. 1 when the output voltage signals from FIG. 3 are applied to it,
- FIG. 5 is a plan view of a portion of the substrate shown in FIG. 1 with media portions different from that shown in FIG output voltage signals controlled application valve from Fig. 1 were applied,
- Fig. 6 is a schematic diagram showing the modification unit shown in Fig. 1 and its placement between the application valve and the main controller.
- the application device 10 shown in Fig. 1 is used in the present example to apply spaced (elongated) portions 11 of flowable medium, in this case hotmelt adhesive, to a substrate 12, in this case a material web 12 (in this case a material web, in particular made of paper).
- a material web 12 in this case a material web, in particular made of paper.
- the web of material shown is just one example of a substrate 12 onto which an application device 10 according to the invention can apply flowable medium. It goes without saying that the invention is not limited to this type of substrate.
- the application device 10 in the present case comprises as a core component an application valve 13 known per se, which in a likewise known manner has a closing element (not shown) which can be moved by means of an electromagnet (not shown) from a closed position in which there is a (lower) Metering opening 14 of the application valve 13 closes, can be moved into an (upper) open position.
- such a closure element In the closed position, such a closure element is generally held by a closure element that applies a closing force, for example a spring that exerts a restoring force, or by permanent magnets that repel one another and in this way apply the restoring force.
- a closing force for example a spring that exerts a restoring force, or by permanent magnets that repel one another and in this way apply the restoring force.
- the closure member forms the armature of the electromagnet and is accordingly made of metal at least in sections, so that the magnetic field generated by the electromagnet can move the closure member into the open position.
- the liquid medium or, in this case, the liquid hot-melt adhesive is supplied to the application valve 13 from a corresponding medium source 34, in this case one Melting device, provided by means of a medium line 15 heated by a heater or a medium hose.
- the electromagnet of the application valve 13 is suitably controlled.
- the application device 10 includes a main control unit 17, in this case a PLC (programmable logic controller), which periodically generates individual, time-spaced output voltage signals 18 (see FIG. 3) and makes them available to the electromagnet of the application valve 13.
- PLC programmable logic controller
- a modification unit 19 which is arranged between the application valve 13 and the main controller 17, in such a way that it receives the output voltage signals of the main control unit 17, then modifies them and finally in a changed form as modified output voltage signals 18 to the application valve 13 or the electromagnet of the application valve 13 forwards.
- the main controller 17, the modification unit 19 and the application valve 13 or the electromagnet of the same are electrically (sequentially) connected in series or arranged in series.
- the modification unit 19 is electrically conductively connected to the main control unit 17 in the manner of a series circuit on the one hand via a first power cable 20a and on the other hand it is electrically conductively connected to the application valve 13 or the electromagnet via a second power cable 20b.
- the main control unit 17 generates the individual periodic, i.e. time-spaced (electrical) output voltage signals with a constant voltage amplitude or constant voltage value of 24 V in each case over the entire signal duration.
- the diagram in FIG. 3 shows two successive output voltage signals 18 that have already been modified by the modification unit 19 .
- a time interval 21 between the two modified output voltage signals 18 can be seen. This also corresponds to the time interval between the unmodified output voltage signals, as received by the modification unit 19 .
- the modification unit 19 ensures that each output voltage signal it receives is modified within a modification period 22 which is shorter than the total signal duration of the respective received output voltage signal or forms a partial period of the total signal duration. In contrast, in an earlier time period 25 or during the remainder of the signal duration, the respective received output signal is not modified, so that the modified output voltage signal 18 forwarded by the modification unit 19 corresponds there to the received or unmodified output signal.
- the modification in the modification period 22 takes place in such a way that a weaker current is set in the electromagnet of the application valve 13 (see FIG. 4) than would be the case without this modification.
- each output voltage signal 18 is clocked for this purpose in the modification period 22, so that the modified output voltage signals 18 (only) in this modification period 22 contain a periodic sequence of individual, in the present case rectangular, signal pulses 23 instead of the constant voltage amplitude over time of the respectively received unmodified output voltage signal .
- each signal pulse 23 is exactly the same as the voltage amplitude of the unmodified output voltage signal.
- Each two consecutive signal pulses 23 are separated from each other by a signal pause 24 or by short periods of time 24 without voltage or with a voltage amplitude of zero.
- the voltage pulses 23 could theoretically also be separated by voltage pulses each having a magnitude greater than zero, but smaller than the voltage amplitude of the unmodified output voltage signals.
- the output voltage signals 18 according to the invention lead in the electromagnet of the application valve 13 to the course of the current I flowing through this shown in FIG.
- the dashed line in FIG. 4 shows the following course of the current curve I, as it would occur without modification of the output voltage signal 18 or without such a modification unit 19 .
- the current I would remain at the value I peak until the end of the unmodified output voltage signal.
- clocking is carried out in such a way that, as a result, the mean value of the voltage amplitude in the modification period is smaller than the voltage amplitude of the unmodified voltage signal, in this case smaller than 50% of the same.
- the effective value of the voltage amplitude is less than 12 volts, preferably less than 10 volts, in the modification period 22 .
- the modification of the output voltage signal 18 is selected such that during the modification period 22 in the electromagnet a holding current I ho id is set which is sufficient to hold the closure element in the application valve 13 in its holding position.
- the electromagnet applies a magnetic force that is lower and can be lower than the opening force that is required in order to be able to move the closure member into this open position during the opening movement.
- this current reduction also means that the electromagnet heats up less during operation than would be the case if it were operated with the (higher) opening current for the entire signal duration. In this way, among other things, undesired influences of the corresponding waste heat from the electromagnet on the flowable medium can be reduced.
- Dashed lines indicate in FIG. 5 how the shape of the corresponding medium portion 11 can disadvantageously adjust when the application valve 13 heats up too much, namely can expand compared to the optimal shape.
- the modification unit 19 has a (protective) housing 26, among other things.
- a driver 27 Inside the housing 26 there is, among other components, a driver 27, namely a suitable electronic circuit which is responsible for the actual modification of the incoming, unmodified output voltage signal.
- a microcontroller 28 is also arranged therein, which is able to analyze the incoming output voltage signal, cf. reference number 29. It can be provided that the microcontroller 28 recognizes operating states of the application valve 13, in particular the electromagnet of the application valve 13 , or faults detected, such as a breakage of one of the power cables 20a or 20b.
- the modification unit 19 can have a preferably electronic memory (not shown). In this, the microcontroller 28 can then store the above-mentioned information about the operating states of the application valve 13 or about errors in the power cables 20a, 20b. This information can be read out or retrieved later if required.
- the modification unit 19 also has an energy supply unit 30, in particular for the driver 27 and the microcontroller 28.
- main control unit 17 it is also conceivable for the main control unit 17 to apply an additional extra-low voltage to the individual output voltage signals, which is then converted by the energy supply unit 30 into usable energy for the corresponding energy-requiring components or units of the modification unit.
- the modification unit 19 has a radio module 31, which makes the determined operating states or other information available via radio to a corresponding (remote) receiver, for example a smartphone 32, in particular after they have been read from the above-mentioned memory or alternatively, a display 33 can also be provided for displaying such information.
