Control unit is designed to control according to the switching of paper roll the coated technique of adhesives.Described switching can be reeled by so-called full width coiling or so-called wide paper injection bar and be carried out, and the paper injection bar here has preset width, is generally 400-600mm, and obtains by the front end that cuts idler pulley 5 paper web before.When wide paper injection bar was reeled, those nozzles 36 that are positioned at beyond the paper injection bar were disconnected.
When paper machine was in the operation, when paper web 1 was wound onto on the spool 6, nozzle 36 was positioned at the dead position of its underpart, and this nozzle has adhesive passage 38, and this passage is towards the bottom vertical orientation of collection cups 53.In this order, air blows via over cap 46 so that preventing dust infiltrates in the nozzle 36, and air blows via air by-pass passage 42 so that keep the exit to avoid dust simultaneously.When for example when coiling full width paper web 1 switches paper roll on empty reel spool 6, spool is reduced to winding position downwards, and nozzle member 14 upwards is switched to the coating position, and wherein the adhesive passage 38 of nozzle 36 is perpendicular to paper web 1 or almost perpendicular to paper web 1 orientation.When empty reel spool 6 contact idler pulleies 5, when the secondary balladeur train (not shown) of backrush device moves forward a bit of distance and is braked by the short time, breather pipe 58 is switched on, form slack 59 (see figure 2)s like this in the interval of paper web 1 between idler pulley 5 and finished product paper roll 7, air from breather pipe 58 acts on this slack 59, and this slack is elevated when forming so-called balloon like this.Thereafter, the source of the gas that leads to the air by-pass passage 42 of nozzle 36 increases, and the source of the gas that leads to over cap 46 is closed.When balloon blowing (balloon-blowing) has begun or after the beginning several seconds, adhesives begin to begin to discharge with the time gap of 0-60 for example second.The discharge of adhesives can at least 1 second, usually carry out in 10 seconds time at the most.Adhesives is applied in the surf zone of paper web 1, and this surf zone crosses whole paper web 1 and extends, and also promptly extends from edge to the edge perpendicular to machine direction.By adhesives, paper web 1 adheres on the new spool 6, so that afterwards it was torn, this is at finished product paper roll 7 and has occurred the result of tension force in now by the paper web 1 between the new spool 6 of reeling paper web 1 around the spool follow-up like this.The blower 58 that is used for the balloon blowing disconnects after the coating of finishing adhesives immediately, and nozzle member 14 is switched to its vertical dead position downwards.The air of air by-pass passage 42 of nozzle 36 of flowing through reduces and source of the gas enters over cap 46 once more.Like this, nozzle 36 remains on a kind of like this state, that is, nozzle has been ready to carry out the up-to-date coating of adhesives, and this adhesives up-to-date for example carried out with preset time after being coated in and reeling in 20 minutes.
In the above-described embodiment, therefore nozzle 36 is configured to take a kind of dead position and a kind of coating position, adhesive passage 38 is vertical orientation when dead position, nozzle 36 is at coating pivot that make progress of the rotation by S. A. 15 during the position, and adhesive passage 38 and paper web 1 basically form the right angle like this.When dead position, adhesives remains in the channel part 40 via the capillary force effect.Because the grit that the air that flows out brings is prevented from sticking to around the outlet of air by-pass passage 42 and outlet is inboard, air is with the relative low velocity air by-pass passage 42 of flowing through, and this speed is enough to make this air by-pass passage 42 to stay open.But the air of outflow must not have a kind of like this speed, that is, thereby the adhesivess that this speed influences in the prepass portion 40 unfriendly are sucked out adhesives, dry then, and the adhesives that has been solidified of export department blocks as a result.Around nozzle 36 and through exporting the air of 50 over caps 46 of flowing through that flow out, should have the speed that is enough to through outlet 50,10m/s for example, thus prevent that grit from infiltrating in the over cap 46.By such layout and these measures, guarantee that nozzle 36 is in operation order until next coating opportunity, carry out the relative long period after coating opportunity formerly on this next coating opportunity.For some reason; if shut down in the paper-making process; nozzle just can not be used so; the planned time point that is used for applying afterwards will exceed; open at regular intervals by the short time in described stopping process for needle-valve 41; a spot of like this adhesives is discharged and is caught by cup-like containers 53 from each nozzle 36, and new adhesive will always be presented in the exit.Like this, the operator perforniance of nozzle between the lay-off period of this common fitfull, prolongation or the quiescent period also be guaranteed.
In the coating position of nozzle 36; the source of the gas that leads to over cap 46 is closed; the air of air by-pass passage 42 of flowing through simultaneously increases to predetermined speed; advantageously influence the rope strand shape adhesives jet 60 of adhesives like this from the airstream 45 of air by-pass passage 42, this adhesives is forced out adhesive passage 38 simultaneously.Because airstream 45 is directed and turn forward on circumference away from elongation center's line 44 of adhesive passage 38, they will influences adhesives jet 60, and the adhesives jet is transformed into the helix in the increase of width on the direction of paper web 1 like this.In addition, 45 pairs of adhesives jets 60 of airstream apply tractive force, help adhesives jet 60 sucking-off channel parts 40.And airstream 45 will produce gas curtain around screw-shaped adhesives jet 60, and the adhesives jet is also transported forward by airstream 45 supportings like this, and keeps together with its helix.
In the above-described embodiment, nozzle need be removable between its dead position and coating position, the ground running because paper web 1 tilts to rise when the position of coating, and also, paper web 1 constitutes acute angle with horizontal surface.Applying under the situation of position level running when paper web, the device of applying adhesive of the present invention has static jet, and this static jet also promptly all has the passage that is used for the vertical orientation adhesives in quiescence and coating state all the time.Therefore in this embodiment (not shown) with static jet, collect the cup-like containers of adhesives and arrange in a movable manner, thereby but make its cross travel, provide play motion so that just in time arrive the adhesives of paper web.For this purpose, their shared cramp bar can be arranged to make its parallel displacement between the primary importance and the second place, described cup-like containers is located immediately at below the static jet when this primary importance, and cup-like containers is positioned at nozzle next door and does not hinder the coating of adhesives when this second place.In the above-described embodiment, use is defined as heating so that the adhesives that can apply.Certainly, can use other adhesives, these adhesivess need not heat and at room temperature be clamminess yet, and perhaps have adhesive effect in the coating occasion at least when paper web contacts with spool.One of them example of the adhesives of the above-mentioned type is a water.
According to another kind of embodiment (not shown), under some occasion, can omit over cap 46 and can make pressurized air through may keep clean to guarantee nozzle by other passage in passage 42 and the nozzle or on every side.
Replace to spray the nozzle of continuous rope strand shape adhesives jet, certainly use the nozzle of spraying form jet or the nozzle of liquid droplets form jet selectively.Figure 11 shows the similar applying device with described first embodiment, except changing into, nozzle member has this nozzle, the i.e. jet 61 of this nozzle ejection Sprayable, Figure 12 and 13 is with the same way as of first embodiment shown in Fig. 9 and 10, schematically show the nozzle that is in dead position and coating position respectively.The nozzle 36 of Figure 11 has over cap 46, and this over cap is with mentioned above similar and operate identical.Nozzle 36 has the centre gangway 62 of the homogeneous mixture that is used to provide adhesives and air, and comprises back channel part 63 and prepass portion 64.Prepass portion 64 is relatively short and narrow.Middle needle 65 is arranged for closes and opens prepass portion 64, and this needle penetrates this prepass portion 64 at least in part so, thereby it is dangerous not have sizable obstruction.In Figure 12, nozzle 36 is in dead position during air supply, and this air is evenly distributed on around the nozzle, so as with after the outlet 50 of over cap 46 flow out, as mentioned above.In other embodiment (not shown), be arranged on fixed position and vertical or be basically perpendicular to paper web with the nozzle 36 of Sprayable applying adhesive.Vertical or when being basically perpendicular to the running of coating plane when paper web, can be easily collection cups or analogue be placed the nozzle below so that collect the adhesives that may drip down from nozzle, special after the coating of finishing adhesives.When paper web level running or when constituting acute angle with horizontal surface, collection cups has hindered the adhesives and the air discharging jet of Sprayable under coating state, collection cups is provided with in a movable manner so that cross travel, thereby makes jet clean catch cup.
When paper web breaks, it also is favourable adopting applying adhesive device of the present invention, and the paper injection bar that wherein provides adhesives is adhered to by coiling on the paper roll that has started.And described applying adhesive device useful binders is adhered to the end of finished product paper roll.
Even it also is rewinding machine or reel packing machine in all types of paper machines and the paper sheet processor that the continuous webs of paper when the present invention has described paper roll (reels) in the backrush device that switches paper machine, this paper web can be used for certainly.
