Definitions

  • the digital printing technique has made it possible to print and collect the sheets and / or sheets in such a way that they each contain the contents of an entire book or printed product. These loose sheets or sheets are not very well suited to being dropped or slipped inside, transported or stacked.
  • This Hilfsverleimung can be done in a variety of ways.
  • a proven technique is that cold glue drops are applied to the outer surfaces of the sheets and / or sheets in the section area of the printed product. With these cold glue drops, the individual sheets and / or sheets, which lie on top of one another, are glued together and thus form a fairly stable book block, which is easy to handle for the further production processes of a bound book.
  • a nozzle unit for processing flowable substances, in particular glue disclosed.
  • a liquid in particular water
  • glue is flushed out of an end portion facing a nozzle orifice.
  • a water column remains in the nozzle channel and seals it to the outside.
  • the closure is moved away and the water column is ejected by the promotion of glue.
  • Adhesive residues accumulate at the outlet opening, harden and then deflect the emerging adhesive jet, which further fouling of the nozzle and thus leads to clogging of the nozzle after a short time.
  • a safe glue outlet can only be guaranteed if the adhesive residues are removed periodically. The period between cleaning intervals may be very small, depending on the adhesive used and the prevailing environmental conditions.
  • a device for applying fluent substances, in particular glue is published on a substrate which contains a fixed support arm and a metering valve connected thereto.
  • the metering valve is arranged pivotably on an axis on the support arm. During the pivoting movement from the working position to the rest position The outlet opening of the nozzle of the metering valve sweeps over the cleaning section of a rubber element and is thereby freed of adhering glue residues. In the rest position, the outlet opening is closed by the smooth sealing portion of the rubber element.
  • the rubber element is preferably arranged on a spring-elastic holder.
  • This device prevents clogging of the nozzle orifice during service stoppages because the orifice is closed and thereby the residual adhesive in the exit bore does not dry and harden.
  • adhesive residues By running over the nozzle outlet opening with the cleaning section of the rubber element hardened or dried adhesive residues are scraped off the nozzle.
  • a disadvantage of the device is that the nozzle for the stripping of the adhesive residues, must be pivoted from the working position to the rest position and back. During this process, the nozzle can not be used to apply glue to the substrate. Furthermore, it has been shown that the adhesive residues relatively quickly pollute the rubber element and this must be cleaned frequently.
  • a similar device is used in the EP 2 006 030 A2 described.
  • the metering valve with the outlet opening for the adhesive, paints or varnishes fixed.
  • a pivotable outer closure is movable between a rest position and a working position adjustable, wherein in the rest position of the outer closure closes the outlet opening of the metering valve.
  • This device has the same disadvantages as the device according to DE 1 99 36 670 C1 ,
  • a liquid dispenser having a water vapor generating source for creating a humid environment at the dye dispenser nozzle, thereby preventing drying of the colorant at the nozzle between uses.
  • US 2008/023034 A1 discloses a nozzle cleaning apparatus and nozzle cleaning method capable of effectively cleaning the nozzle for discharging a processing liquid onto a substrate.
  • the nozzle itself is equipped in a cleaning tank with a funnel-shaped section.
  • a solvent provided as a cleaning liquid becomes along an inner surface supplied to the funnel-shaped portion.
  • the solvent forms a vortex flow around the nozzle. This allows the nozzle to be cleaned.
  • EP 2 248 598 A1 For example, an apparatus and method for dispensing a moisture-curing adhesive has become known.
  • the device has a plurality of nozzle openings which are operable in two operating modes. In an operating mode, not all the nozzle openings are in operation, so that precautions must be taken so that the unused nozzle openings do not stick together.
  • the residual adhesive at the exit opening of the nozzle comes into contact with the outside air, in which moisture is in contact, and thereby hardens.
  • the curing of the adhesive is by a flow chamber in the region of the nozzle opening prevented by a gas is introduced into this flow chamber, which flows around the outlet opening of the nozzle with the adhesive residues and thus the moisture from the air can not come into contact with the adhesive.
  • This device is designed and proven for moisture-curing adhesives such as PUR and the like. However, the device is not suitable for cold glue adhesives that cure by drying. It has been shown in experiments that the flushing of the outlet opening of a nozzle operable with cold glue with dry air or a gas that does not prevent fouling of the nozzle by adhesive residues, but rather promotes.
  • the invention aims to remedy this situation.
  • the task is based, with an order of a flowable material, in particular a glue, in particular a cold glue to prevent the contamination or clogging of nozzle valves, so that a high and guaranteed availability of the system Applying the glue can be ensured without having to resort to manual or mechanical cleaning operations of the nozzles during production or in the course of production interruptions.
  • the proposal according to the invention is based on the findings that a nozzle clogging can be set up, in particular, but not only, easily during an operational downtime of the nozzle valve. If no adhesive is expelled over a longer period of time, the adhesive remaining in the nozzle outlet opening can dry out and form a plug, which then stubbornly closes the nozzle outlet opening. In order to keep the outlet opening of the nozzle better free, needle valves could be used per se, through which the nozzle outlet opening can be closed with a pen if necessary. However, it has been shown that even equipped with such an infrastructure nozzle outlet openings be easily closed by such lumpy adhesive residues and can lead to inoperability.
  • the latter can be done, for example, when the air is treated by means of a mist generator or a water-fed ultrasonic atomizer.
  • Condensation also known as condensation
  • condensation is a wet, misty deposit on objects, with condensate always forming when moist, warm air hits a cold or colder surface.
  • Warm air can bind much more water than cold air. When warm air cools down, the excess amount of water in the air settles in the form of condensation.
  • At least one zone of the nozzle end is subjected to cooling and acted upon by a moist and / or moderately moderated air, such that forms by the Impact between the supplied moist and / or temperature-moderated air and the cooled zone of the nozzle end, a condensate amount
  • This condensation is responsible for the fact that it is continuously counteracted drying or sticking of the flowable substance at the nozzle outlet opening of the nozzle end.
  • the solution according to the invention makes it possible that manual or other cleaning of the nozzles during production or on the occasion of production interruptions activated for cleaning purposes is completely eliminated, as a result of which high productivity can be maintained.
  • the nozzle valve is part of a comprehensive nozzle assembly, which includes other functional elements, such as Klebstoffzu réelle Gustav, moist air generator, dry air supply, water supply, drainage device, etc. (Reference is made to the description of the figures).
  • the contamination is usually caused by adhesive residues, which accumulate in the area of the nozzle outlet opening and dry, and can also mix with dust particles from the ambient air.
  • adhesive residues which accumulate in the area of the nozzle outlet opening and dry, and can also mix with dust particles from the ambient air.
  • Such pasty mixture is predestined to dry out easily, so that over time, clumps may form, which hang on the opening of the nozzle outlet opening, and thus completely prevent the glue feed from the nozzle outlet opening or significantly distracting, which leads to erroneous operations in the specific application of the adhesive.
  • the condensation water which originates in the region of the nozzle end and the nozzle outlet opening then flows off, thereby entraining dirt particles and possible glue residue particularly up to the nozzle outlet opening in such a way that continuous cleaning on the one hand of the nozzle end and on the other hand of the nozzle outlet opening takes place.
  • the condensate is contaminated with a certain amount of dirt particles, a corresponding discharge of condensed water must be provided by acting continuously or intermittently with a lateral jet of air on the nozzle outlet opening, which blows away there accumulating condensation, which condensate then arranged in a laterally Collection collected and then derived.
  • the air jet can intermittently and additionally be used with a higher pressure pulse, but in any case it should not adversely affect the consistency of the glue jet flowing out of the nozzle outlet opening.
  • a protective effluent device is provided, which is oriented exclusively on the discharge of such a charged condensed water. This drain device must be able to shield the end nozzle outlet from the dripping or draining condensation, so that the glue to be applied does not come into contact with this condensation.
  • a corresponding embodiment variant of this drainage device according to the invention consists in that it closes the immediate nozzle outlet opening in the shape of a contour, so that the condensation water can flow off integrally on the circumference of the nozzle end via the drainage device.
  • a metered subset of the moist and / or temperature-moderated air is passed through preferably specially attached and designed flow openings in the interior of the drain device, said air flow is preferably directed directly to the nozzle outlet opening, which undergoes a continuous lubricating effect by the moist air.
  • the flow openings within the drainage device may further be formed so that the air flow through these flow openings a undergoes certain acceleration, which in turn maximizes the lubricating effect in the region of the nozzle outlet opening, whereby then the risk of a closure of the nozzle outlet opening by glue lumps finally tends to zero.
  • the supplied air has a high degree of purity, and this is achieved, for example, that this air is enriched with a corresponding amount of distilled water. In any case, this air should not come in contact with dirt contaminated condensate before acting on the nozzle outlet opening. It is also advantageous if the air / water mixture is designed so that the conditions for a high-fogging air flow are met, with which then an unimpeded flow of the glue stream is ensured.
  • the discharge device with tangentially applied air holes through which the air flows into the interior of the discharge device, and there, preferably in the region of the nozzle outlet opening, forms a swirl flow, which together with the lubricating effect against the nozzle outlet opening also a consolidation of the flowing in the center of this swirl flow glue jet due to the forming there cyclone effect guaranteed.
  • This air-swirling flow is then discharged either axially or tangentially with respect to the axis of the nozzle outlet opening, but without being detrimental to the compactness of the glue jet.
  • this air swirling flow can also entrain and dissipate any condensate drops forming on the inner wall of the outflow device.
  • Such a constellation occurs when the nozzle exit opening is not fully contoured completed by the drainage device, or can be completed, but when operated between the two parts with a contoured gap through which smallest condensed water drops can pass into the interior space of the drainage device.
  • this gap should preferably be dimensioned such that any condensation water droplets forming on the inner wall of the drainage device and adhering there due to their surface tension can easily be entrained by the injected air swirling flow.
  • the final purpose of the invention based on the one hand to cool the nozzle end with the nozzle exit opening for the glue supply by a coolant or a cooling device.
  • the cooled nozzle end is then blown or circulated through moist and / or temperature moderated air.
  • this air flow has a higher temperature than the prevailing temperature at the nozzle end.
  • the condensate forming by this impact fogs the outer surface of the nozzle end and thereby prevents the glue from drying out and also the formation of glue lumps in the area of the nozzle outlet opening.
  • the provisions for the discharge of contaminated with dirt particles condensate in the context of a drain device must be designed and aligned so that the aforementioned condensation is safely routed to a bottom collecting tray and collected there, and then from time to time to be sucked with a suction device, wherein the drip pan can also be covered with sponge-like mats, which can be replaced at full load with dirt particles or the dirt particles can be sucked through a drying process.
  • FIG. 1 For the sake of general explanation, the application of a nozzle valve 1 for applying dots of glue to printed products is shown, which is then used for the formation of an auxiliary glued book block.

  • FIG. 5 shows a further sectional view of the nozzle assembly, at right angles to the representation in FIG. 4 in the area of the moist air generator.
  • the water supply is controlled by a water supply regulator 19, which preferably increases the supply of the amount of water at elevated temperature in the humid air generator 3 via a control.
  • the dry air is heated by the heat generated from the Peltier element 10 and enriched in the humid air generator 3 with water.
  • the warm, moist air then passes via a line 11 in a distribution plate 7, and from there the water enriched air is conveyed through arranged in the distribution plate channels 12 into a nozzle chamber 13.
