Definitions

  • the invention relates to an application liquid which is applied by means of an application head in the form of a linear liquid application to a substrate, in particular a paper web entering a folder, and according to further inventive ideas relates to a method and a device for producing a liquid application on a Substrate.
  • the application liquid used contains pigments which are invisible under normal light and which are visible when exposed to associated visualization agents.
  • the pigments are invisible under normal light, there is advantageously no need to fear a deterioration in the quality of the substrate treated with the liquid according to the invention.
  • the pigments in the visualized state enable simple measurement of the position of the line-shaped liquid application and simple function control of the application device. As a result, high product quality can therefore advantageously be maintained even over long operating times.
  • the procedure can simply be such that the liquid application is made visible and that the distance of the line formed by the application liquid is measured from the desired position and, in the event of a deviation, the assigned application head is adjusted.
  • an application head for applying a linear liquid application, in particular a glue application, to a substrate one can simply proceed in such a way that the pigments of the liquid according to the invention, which afterglow when excited, are excited and observed in the normally moving area and that depending on whether afterglow is recorded or not, the application head is replaced.
  • the functional check can expediently be carried out in such a way that the coating liquid containing afterglowing pigments is exposed to visualization agents prior to their application to the substrate and when observed the application head is replaced at the same location during the full afterglow period.
  • a simple device for setting an application head which is accommodated on a holder which can be adjusted by means of a preferably remote-controlled actuating device, can consist in that a measuring table provided with a measuring scale is provided, on which a folded product can be placed and which is provided with visualization means, and that the actuating device assigned to the application head can be activated during operation and that a display device indicating the actuating path is provided.
  • This device advantageously enables manual control, in which a single folded product is removed from a shingled stream leaving the folder, placed on the measuring table and measured there, and by adjusting the application head depending on the measurement result, the associated measuring scale being used in conjunction with the display device showing the travel path ensures high accuracy and short readjustment times.
  • an expedient device for checking the function of an application head can contain at least one visualization agent source assigned to a moving pigment carrier, preferably in the form of a flash device, and at least one sensor matched thereto, by means of which the afterglow of the afterglow pigments can be measured and by means of which an alarm device can be activated.
  • the longitudinal folding device on which FIG. 1 is based consists of a funnel folding device 2 which is arranged over two folding rollers 1 and over which a printed paper web 3 is drawn in order to achieve a longitudinal fold.
  • the web is divided into sections by means of a cross cutting device which can be subjected to a further folding process.
  • a folding auxiliary liquid is applied to the paper web 3 along a line 4, which coincides with the folding line produced by the gap between the folding rollers 1 and the former nose of the former folding device 2 during the folding process.
  • the folding aid liquid is intended to soften the paper material along the folding line, so that an exact, sharp-edged fold can be achieved.
  • the folding aid liquid can be applied contactlessly by means of a hollow needle or, as here, by means of a nozzle 5.
  • the nozzle 5 is received on an applicator head 6, which is mounted by means of an associated holder 7 on a crossbar 8, which is fastened to the frame side walls 9 of the folder superstructure or the printing machine arranged upstream of the folder.
  • the application head 6, which is provided with switching elements for opening and closing the nozzle 5, is supplied with a folding aid liquid through a feed line 10.
  • the switching elements of the application head 6 can be remotely operated by means of a control line 11 from a control panel 12.
  • the position of the nozzle 5 is by accordingly moving the holder 7 along the crossbar 8 above Width of the web 3 adjustable. In simple cases, this setting can be made manually.
  • an actuating device 13 which can be remotely controlled from the control panel 12 is provided for this purpose and can be controlled via a control line 14.
  • Heated tap water can be used as a crimping aid.
  • absorbent paper such as newsprint, etc.
  • heating to about 30 ° C. is sufficient. You can work at a higher temperature for problem papers. In particularly stubborn cases, chemicals can be added to the water.
  • the folding aid liquid used here also contains pigments that are not visible in normal light and that can be made visible using a suitable visualization agent. Color pigments that are visible under UV light can be used for this purpose. Therefore, only a UV lamp is required to make it visible. This makes it possible to check whether the line 4 generated by the folding aid liquid coincides with the folding line or not by making the line 4 visible. The fold line is visible anyway. A possible distance can thus be measured.
  • a measuring table 15 is provided in the illustrated embodiment, to which a visualization means, here in the form of a UV lamp 16 that can be switched on and off, is assigned.
  • the measuring table 15 is arranged here directly next to the control panel 12.
  • a length scale 17 is provided, by means of which a possibly existing distance a between the visible folding line 18 and the folding aid liquid line 4 made visible by means of the switched-on UV lamp 16 of a folding product 19 placed on the measuring table 15, here unfolded, can be made visible.
  • a folded product 19 is removed from a shingled stream leaving the folding apparatus and, as is indicated by a dash-dotted line 20, brought onto the measuring table 15.
  • the length scale 17 can, as here, be installed permanently or arranged loosely.
  • the UV lamp 16 can be provided with a switch button 21 for switching on and off.
  • the application head 6 is then actuated appropriately by the actuating device 13 from the control panel 12 provided with assigned control buttons 22 by the same amount, ie also by the distance a, adjusted.
  • a length scale 23 is also provided in the area of the control panel 12, which is assigned a pointer 24 which can be adjusted synchronously with the application head 6.
  • a digital display could of course also be provided. It would also be conceivable to assign an automatic scanning device to the length scale 17 of the measuring table 15, by means of which the control device 13 can be controlled automatically.
  • an automatic regulation of the position of the application head 6 could also be provided.
  • a measuring device integrated in the folding apparatus for the continuous monitoring of the correspondence between folding line 18 and folding aid liquid line 4 could be provided, the output of which is used to control the adjusting device 13.
  • the applicator head 6 'shown in FIG. 2 consists of two parts, namely a base part 25 fastened on a holder 7' and a plug-on part 26 which can be releasably fixed thereon .
  • the base part 25 is attached to the holder 7 'and serves as a receptacle for the end of a supply line 29 on the application head side which contains all the supply lines, here in the form of a folding aid liquid supply line 30 and a glue supply line 31 and any electrical lines that are still required and are not specified in any more detail.
  • the supply lines ending in the base part 25 can be coupled by plug-in couplings with corresponding extensions in the plug-on part 26.
  • the glue supply line 31 has a transparent section 32 provided in the area of the stationary base part 25.
  • the flash device is activated intermittently.
  • the sensor 34 arranged on the same optical axis as the flash device 33 can be continuously active or can be activated with the flash device 33.
  • the nozzle 27 or the like is blocked no movement, so that the pigments excited in this case remain in place. If there is no glue flow in the glue feed line 31, that is to say there is a blockage in the nozzle 27, for example, after the flash device 33 has been activated, the sensor 34 is subjected to afterglow light during the entire afterglow period of the afterglow pigments when activated. In this case, the sensor 34 generates an output signal, which is led via a signal line 35 to a control device 36, by means of which a corresponding alarm device 37 can be activated with appropriate control.
  • the sensor 34 aligned with the flash device 33 will not during a flash emitted by the flash device 33 as a result of the movement of the glue acting here as pigment carrier and accordingly the further movement of the pigments of the entire afterglow period with afterglow light.
  • the output of the sensor 34 remains inactive in this case, so that the control device 36 is not activated and the alarm device 37 is not triggered.
  • a sensor 38 is assigned to the sensor 34, which only activates the output via a comparison circuit that can be activated with the flash device 33 if afterglow light is received over a predetermined period of time.
  • the timing of the flash device 33 and the aforementioned comparison circuit can be accomplished by the control device 36, which is indicated by signal lines 39.
  • the plug-on part 26 containing the wearing parts can simply be replaced. This is possible within a short time and with little operating effort.
  • the required material is also low, since the plug-on part 26 contains only the wearing parts and the base part 25 is retained, in which the monitoring device is also integrated here.
  • the integration of the monitoring device in the form of the flash device 33 and the sensor 34 with an associated time measuring element 38 into the stationary base part 25 of the application head 6 ensures reliable protection of the monitoring device against external influences and nevertheless ensures that the monitoring device does not change every time the plug-on part 26 is changed must be changed.
  • afterglow or non-afterglow pigments can be used.
  • the web 3, which functions here as a pigment carrier, is acted upon in the area of the line-shaped glue application by means of a light source, in the case of afterglow pigments, by means of a flash device and in the case of non-afterglow pigments which only appear when exposed, by means of an exposure device, such as a UV lamp scanned by means of an associated sensor.
  • the sensor is so oriented that it picks up the reflection during the exposure in the case of non-afterglow pigments and, in the case of expediently used, afterglow pigments, the afterglow light of which picks up In any case, the lack of light reception by the sensor means a malfunction.
  • the circuit of the sensor is therefore such that an output signal is generated if the sensor does not receive a light signal after activation of the visualization source.
