Definitions
- the invention relates to a gluing station for applying glue to product elements guided in a product stream. It also relates to a method for operating such a gluing station.
- glue When producing flat paper products such as envelopes, mailers and similar products or when producing single or multi-layer fiber or tissue products such as hygiene products, handkerchiefs, toilet paper or the like, it may be necessary to apply glue to the products be.
- the glue for later gluing the envelope flap is applied to this.
- the glue is re-moistened by the moisture in a sponge or in the saliva and thus activated.
- the application of the glue to the products usually takes place in that the product elements are led past a gluing station in a product stream, for example an imbricated stream.
- the glue can also be applied selectively or in block form to staggered or individual products.
- the gluing station usually comprises a glue application roller to which the glue is applied from a glue bath or a glue pan by means of an upstream scoop roller and an interposed transfer roller.
- the glue application roller for its part, rolls on the product / product flow and transfers the glue on its surface to the product elements.
- the glue application roller is thus continuously glued by the glue unit, and it then gives this glue to the z. B. carried out in the product stream product elements, especially the paper, immediately.
- the glue application roller is swiveled away from the medium and the glue unit and the glue application roller are also separated.
- the glue unit is usually kept in motion by a motor that continues to run and continuously supplied with fresh glue, while the glue application roller is not moved.
- the glue on the application roller begins to dry gradually. This means that when the production process is restarted and the
- the invention is therefore based on the object of specifying a gluing station of the type mentioned above, with which the production process and the gluing of the product elements can be continued in a particularly simple and reliable manner even after a temporary machine stop or production standstill. Furthermore, a method for operating such a gluing station is to be given.
- this object is achieved according to the invention in that a moistening system is assigned to the glue application roller.
- the invention is based on the consideration that the difficulty in continuing the production process after a machine standstill, which is regarded as disadvantageous, is particularly due to the drying out of the glue which begins during the standstill of the gluing station. This is made even more difficult by the fact that the glue, in the comparatively moist state in which it is usually processed in the gluing station, usually has a lower adhesive strength, especially with the rewettable glue that is preferred for the production of envelopes. or adhesive strength than with increasing mender drying. The drying out of the glue not only makes handling more difficult, but also increases the risk of a disadvantageous impairment of the subsequent process steps due to increasing sticking.
- the glue application roller is assigned a moistening system in the sense that the (residual) glue on the surface of the application roller can be kept moist while the system is idle, i.e. H. that the surface of the application roller can be supplied with moisture in an amount that is at least sufficient for this.
- the glue application roller is preferably designed as a rubber roller.
- the moistening system is advantageously designed for moistening the glue with water as a moistening agent.
- a particularly effective and efficient humidification can be achieved by supplying the water to the roller surface in the form of a water mist or a moist air stream.
- the humidification system therefore particularly preferably comprises a water nebuliser
- the moist air flow is close to the surface, that is to say preferably in such a way that particularly efficient application of the roller surface is made possible, to the glue application roller.
- the water nebulizer is advantageously designed as an ultrasonic nebulizer, in particular with a fan, or includes one.
- the guidance of the moist air is designed for a particularly efficient, uniform and precise wetting of the surface of the glue application roller.
- the water nebulizer is advantageously combined with an outlet nozzle for the water mist or moist air flow, via which the water mist can be fed to the surface of the glue application roller in a laminar flow, preferably at a suitable angle of attack. This ensures that the supplied water mist can largely cling to the roll surface after it has flowed out of the outlet nozzle, so that particularly effective wetting with precipitation of the water mist on the roll surface is made possible.
- a particularly good transfer of the water mist generated to the roller surface can be achieved in that the water mist device advantageously has a collection chamber for excess water mist in the mist exit area.
- the excess moistening agent collected in the process can thus be returned directly to the roller surface, and an intrinsically undesirable introduction of the moistening agent into other parts of the system can be minimized or possibly completely avoided.
- the above-mentioned object is achieved by swiveling the glue application roller away from the product flow for the duration of the standstill in the case of a particularly temporarily stopped product flow and keeping the surface rotating the glue application roller is moistened.
- intermittent moistening of the glue application roller or intermittent or piece-wise rotation of the glue application roller can also be provided.
- a water-based dextrin glue (re-moistenable) is preferably used and in an embodiment that is regarded as independently inventive in a gluing station of the type mentioned above.
- a glue in particular already has a comparatively strong adhesive effect at the onset of drying, which in particular can significantly exceed the adhesive effect in the moist state.
- the provided glue moistening during the standstill phases can particularly favor the subsequent, preferably approximately interruption-free continuation of the production process, since the glue remains limited in its adhesive effect due to the moisture retention and an undesirably strong sticking or sticking of the product parts after resumption the process can be kept limited.
- the advantages achieved with the invention are, in particular, that through the moistening system assigned to the glue application roller, effective continuous moistening of the glue on the surface of the glue application roller can be achieved, so that its further processing is particularly reliable and even after temporary standstill phases of the production process is made possible in a particularly simple and cost-saving manner.
- FIG. 1 shows a production plant for the production of envelopes
- FIG. 2 a gluing station of the production plant according to FIG. 1.
- FIG. 1 is intended for the production of envelopes, Briefumschlä conditions 2 and / or mailers, each provided with a closure flap with adhesive zones.
- the production plant 1 comprises several stations in a conventional design, of which in FIG. 1 only parts of a bottom flap folding station 4 and a side flap folding station 6 are shown schematically. From the side flap folding station 6, the envelopes 2 (and the like) pass into a stacking station 8 with a relay wheel 10.
- a glue or adhesive 22 is applied to the inside of the closing flaps of the envelopes 2 or shipping bags. After that, products are pulled apart a little so that the glue doesn't stick the products together.
- the adhesive 22 forming an adhesive zone is then dried in the drying section for further processing.
- the gluing station 20 is shown in FIG. 2 shown enlarged. It comprises a glue pan 28 in which the glue or adhesive 22 is held ready for processing.
- a scoop roller 30 is partially immersed in the glue 22 held in the glue tank 28, so that when the scoop roller 30 rotates about its longitudinal axis, a portion of the glue 22 adheres to the surface and is thus conveyed out of the glue tank 28.
- Rolling on the surface of the scoop roller 30, a transfer roller 32 is arranged to which the glue 22 adhering to the surface of the scoop roller 30 is transferred.
- a glue application roller 34 in the form of a rubber roller can be pivoted onto the transfer roller 32 and, in the pivoted-in state, also rolls on the product flow 12 formed by the product elements, in the exemplary embodiment the envelopes 2.
- the product flow 12 is guided past the gluing station 20 in the transport direction indicated by the arrow 36 so that the glue 22 located on the surface of the glue application roller 34 is transferred to the desired positions of the product elements or envelopes 2.
- a process disruption or from Ma In the event of a machine or production stop in which the further transport of the product flow 12 in the transport direction is temporarily interrupted, for example as a result of a production error, a process disruption or from Ma
- the glue application roller 34 is temporarily out of the position shown in FIG. 2 swiveled out working position and separated from the transfer roller.
- the so-called glue unit i.e. the ensemble of scoop roller 30 and transfer roller 32, is based on demand or kept in motion unchanged by an ongoing motor (not shown in detail) and continuously supplied with fresh glue 22, so that the glue 22 dries on due to the continuous pulp exchange is prevented.
- the gluing station 20 is now specifically designed so that in such a state of the temporary production stop, the drying of the glue 22 on the surface of the glue application roller 34 is avoided in a particularly simple and reliable manner, so that after the temporary production stop has ended a particularly efficient and simple continuation or resumption of the production process can take place.
- a moistening system 38 assigned to the glue application roller 34.
- the moistening system 38 is very preferably designed for a needs-based supply of a moistening agent, in the exemplary embodiment water, to the surface of the glue application roller 34.
- this feed is to take place as a water mist in order to ensure a resource-saving and yet very efficient use of the humidifying agent.
- the humidification system 38 comprises a water mist generator 40.
- the water mist device 40 with its outlet nozzle 44 is suitable for the intended mode of operation and positioned close to the surface of the glue application roller 34 so that the water mist generated can be efficiently fed to the glue application roller 34.
- the water nebulizer 40 comprises an ultrasonic nebulizer 42 as the actual nebulization element.
- the humidification system 38 is also provided or combined with a suitably selected and dimensioned outlet nozzle 44 for the water mist.
- the water mist generated by the ultrasonic atomizer 42 is transported to the outlet nozzle 44 by a fan 48 and a suitably selected hose 50.
- a collection chamber 46 for excess water mist is also arranged. At the outlet of the nozzle 44, the water mist that may bounce off the surface of the glue application roller 34 does not escape directly into the machine environment, but rather lets it remain on the glue application roller 34 or on the glue 22 as far as possible.
- the glue application roller 34 In operation of the production plant 1 or the gluing station 20, in the event of a stopped product stream 12, the glue application roller 34 is pivoted from the product stream 12 and from the transfer roller 32 and kept rotating, the surface of the glue Application roller 34 is moistened. When the production system 1 starts up again, the glue application roller 34 is preferably first coated with glue a few turns before it is swiveled towards the transport path. This is to ensure an optimal glue consistency
- a water-based, rewettable dextrin glue is used as glue 22.
- glue 22 When drying begins, this shows a clearly viscous deterioration compared to the still liquid state. increased adhesive effect. It can also be reactivated when drying begins by adding water or washed off non-absorbent surfaces. Its viscosity is preferably around 4450 mPA * s, its solids content around 67% and its density around 1.16 g / ml.
