Definitions

  • the invention relates to a method and a device for cleaning an at least one fluid outlet opening comprising applicator for applying a fluid medium, in particular traces of an adhesive, on a relative to the fluid outlet opening moved Good, especially on a tab of a corrugated board, also called "Laschenbeleimung”.
  • the plate gluing is a process step in the production of corrugated boxes, which takes place for example in plants, which are also called “Inliner (Flexofoldergluer)".
  • This manufacturing process in the corrugated board industry is increasingly automated, so that the plants must work as far as possible without intervention of the operating personnel.
  • the invention has found its starting point in gluing devices for this plate gluing, so that it will be described below using the example of the same.
  • the field of application of the invention is not limited to gluing devices. It is also possible to realize the invention in connection with other applicators for applying a fluid medium.
  • the glue application nozzles which each have at least one glue outlet opening, mainly work in contact with the corrugated cardboard blank.
  • the glue application nozzles or their glue application openings are not automatically cleaned or sealed against drying.
  • the glue is applied, depending on the direction of folding of the system and type of corrugated box (inner flap or outer flap) from above or below, on the operating or drive side of the system.
  • the glue application nozzles become dirty during production due to cardboard abrasion and adhesive residues. This causes an irregular or intermittent glue application and thus insufficiently or incorrectly glued corrugated boxes due to deflection, delay or shutting off a leaking from the glue outlet opening of the glue application nozzle glue application. Therefore, the glue application nozzles must be cleaned at regular intervals by the operator of the system. For this purpose, the entire system must be stopped, as access via safety devices is only permitted when the system is down.
  • the invention is therefore based on the object to provide a device in which the risk of clogging fluid outlet openings, in particular a glue outlet opening of a glue application nozzle is reduced.
  • the application device - in particular the glue application device - is moved from a working to a cleaning position. Subsequently, the fluid outlet opening - in particular the glue outlet opening - an application nozzle is acted upon with liquid.
  • the inventive method is thus characterized by the significant advantage that in production interruptions not only a closure of the outlet openings takes place, but these actively cleaned and liquid by a drying of the medium located in the application nozzles - in particular the glue - is prevented.
  • the fluid outlet opening is exposed to liquid by immersing the fluid outlet opening in a liquid volume.
  • the application device comprises an application nozzle, this is introduced over a part of its length into the liquid volume.
  • the fluid outlet opening can be charged with liquid by sweeping the fluid outlet opening with a cleaning device charged with liquid.
  • the cleaning device may comprise a roller device.
  • liquid is used in the process according to the invention which contains a solvent of the fluid agent.
  • the fluid agent is, for example, a dispersion adhesive, which is used in particular for the adhesion of latches because of its environmental compatibility, then the fluid comprises, for example, water.
  • the sequence of the method steps of the method according to the invention is preferably controlled or regulated by the control device of an application system.
  • a device according to the invention for applying a fluid medium, in particular a glue with an application device, in particular a glue applicator, which has at least one outlet opening for the fluid medium, on a moving relative to the outlet opening Good, in particular on a corrugated cardboard cut, according to the invention the applicator between a work and a rest position relocatable. Furthermore, the device has a cleaning device, by means of which the outlet opening in the rest position of the application device can be cleaned under the action of liquid.
  • the device according to the invention is thus characterized in that during production pauses the outlet openings can be actively cleaned, so that clogging thereof is reliably prevented by drying of the discharged medium or by contamination.
  • the cleaning device comprises a liquid volume, in which the outlet opening of the applicator can be introduced. Due to this measure not only soiling is removed during the rest periods of the device, but the outlet opening is closed by the surrounding liquid from the ambient air, so that a drying of fluid residues in the outlet opening is prevented.
  • the at least one outlet opening is formed by at least one application nozzle.
  • the volume of liquid may then in particular be received by a container comprising a lid provided in the position of the application nozzle with a passage equipped with a sealing seal which automatically releases the passage upon introduction of the application nozzle and automatically after removal of the application nozzle closes. Due to this measure, the liquid volume is permanently in a closed container, so that evaporation of the liquid and the ingress of contaminants are reliably prevented.
  • the cleaning device of the device according to the invention may comprise a liquid-wettable device with which the discharge opening can be painted over.
  • This device may for example be designed as a roller device comprising at least one rotatable cleaning roller, which is displaceable under contact with the outlet opening relative to this. The roller is then moved in rotation past the applicator device at the exit opening. Due to the rotation of the roller, the outlet opening is also cleaned mechanically particularly effectively.
  • the cleaning roller can be brought into a stationary position which closes the outlet opening. Due to this measure, the cleaning roller not only cleans, but also acts as a closure, so that even with prolonged plant downtime drying is still in the applicator fluid medium is prevented.
  • the supply of the liquid to the roller device can basically be done in any way. However, it is particularly preferred if the roller device comprises a liquid bath in which the cleaning roller is immersed with a part of its circumference. By the rotation of the cleaning roller during the cleaning process, this always entrains a certain amount of liquid, with excess liquid flows back into the liquid bath.
  • the roller device may comprise a transfer roller arranged in the fluid bath which cooperates with the cleaning roller and by means of which liquid is supplied to the cleaning roller.
  • the adhesive supply 100 sucks the adhesive out of a container 110 and delivers it under pressure via a pump 120 and a pressure regulator 130 to the gluing device.
  • the glue pressure is in each case controlled in accordance with the product speed during the gluing process in such a way that uniform amounts of glue are emitted from glue application nozzles 230 (see, for example, FIG.
  • the gluing device 200 comprises a blank guide 220, the glue application nozzles 230 and a cleaning device 240.
  • a corrugated cardboard blank 10 passes through the blank guide 220 and is held in position by it in such a way that a nearly uniform, vertical distance from one to be glued tab 11 of the blank 10 is adhered to the glue application nozzles 230.
  • the glue application nozzles 230 are vertically attached at a distance from the surface of the glue flap 11 of the corrugated cardboard blank 10 and apply the glue in glue tracks 12 to the continuous glue flap 11.
  • the glue application nozzles 230 can be moved horizontally via a transfer device 244.
  • the cleaning device 240 is vertically movable via a transfer device 243.
  • the gluing station is in the working position, i. the glue application nozzles 230 are located above the glue tab 11 and the cleaning device 240 in the lower position ( Figure 2).
  • the gluing device In production interruptions, the gluing device is transferred to the rest position.
  • the glue application nozzles 230 are moved away horizontally transversely to the advancing direction of the glue flap 11 by means of the transfer unit 244, and subsequently the cleaning device 240 with the transfer unit 243 is moved vertically upwards.
  • the glue application nozzles are cleaned and hermetically sealed in order to prevent the glue from drying out (FIG. 3).
  • the gluing device Before the start of production, the gluing device is returned to working position.
  • the cleaning device 240 is moved vertically downwards with the transfer unit 243 and subsequently the glue application nozzle 230 is moved over the glue tab 11 by means of the transfer unit 244.
  • a liquid bath 241 is provided.
  • the liquid bath 241 comprises a container which is filled with a liquid which dissolves the adhesive (in the case of dispersion glue, for example, with water), so that the glue application nozzles 230 submerge in the rest position.
  • the liquid prevents the glue application nozzles from drying through air-tight sealing and dissolves adhesive residues.
  • the container is closed with a lid provided in the position of the glue application nozzles 230 with passages equipped with elastic closure seals 242.
  • the closure gaskets 242 clean the glue application nozzles 230 when immersed in and exiting the liquid bath. Furthermore, the entry of paper abrasion in the liquid bath is significantly reduced.
  • a further advantageous embodiment which is shown in FIG. 4, comprises a liquid wetted roller device 245, which achieves a further improvement of the cleaning effect by a relative movement to the glue application nozzles 230.
  • the rolling device comprises a liquid tank 246, a cleaning roller 247, the surface of which is formed of an elastic material, and a roller drive 249, which sets the cleaning roller 247 in a rotating movement.
  • the cleaning roller 247 is in a position that its outer periphery sweeps over the glue application nozzles.
  • the glue application nozzles dip into the cleaning roller.
  • the glue outlet openings are thus effectively closed by the cleaning roller.
  • the cleaning roller is rotated for cleaning until the dirt adhering to the nozzles is removed. Dirt will be in the passage of the Scope of the cleaning roller detached by the liquid bath.
  • the glue application nozzles 230 are sealed airtight by the moist roller and protected against drying.
  • the cleaning device additionally comprises a transfer roller 248 which is disposed within the liquid bath and the liquid transfer to the cleaning roller 247 accomplished.
  • the glue application nozzles 200 are opened and closed as a function of the predetermined glue pattern and the current position of the corrugated cardboard blank 10 via a positioning and metering control 300 (see FIG. Further, with the positioning and dosing control 300, the glue pressure generated by the adhesive supply 100 is regulated and the drive for the transfer of the gluing device from the rest position to the working position and back is actuated. The triggering of the transition is carried out by signal input from the control of the system or time-controlled depending on the contamination behavior of the glue application nozzles.
  • the positioning and dosing control 300 reports the operational readiness of the gluing device, when it is in working position, to the control of the system and thus gives or prevents the start of production when the gluing device is at rest.
  • the data exchange can be established via hardware signals or via a fieldbus connection.
  • the data exchange can be uni- or bidirectional.
