Description
Technical field
The present invention relates to a kind of have the feature of the preamble of claim 1 for offset printing trace (Leimspur) being coated to the device on the parcel band of the bar form articles of tobacco.
Background technology
Parcel band is generally used for and carries out shape to bar form articles and fix, and this bar form articles can be such as prefabrication, as filter stick or tobacco, or also can be the product made, such as cigarette, cigarlet, has and does not have filter tip.
First wrapping strips band turns to and is applied on the conveyer belt of ring-type in continuous print manufacture process.Next by the fibroplastic filter-tip material of loose filter-tip material, filter tip section or also the bar (Strang) of loose baccy fiber be laid into and wrap up on band.Parcel band utilizes the bar laid to be guided by shaping section subsequently, and in this shaping section, parcel band is rolled-up and be furnished with thin offset printing trace in side, an edge at the sidepiece of bar.The following band that will wrap up continues around bar crimping, until the overlapping edges of parcel band.Afterwards, parcel band side, edge by apply very little pressing force and/or heat energy mutually bonding via glue-line (Leimnaht), thus bar next on cross section by wrap up band fixed by shape.Alternatively, offset printing trace also can utilize with the form of glue point (Leimpunkten) the spacing coating determined, such as, be this situation when filter tip section is adhered to by gummed.Glue point and the strand material center in this case on parcel band is coated away from the position before wrapping strips band crimping one, and for filter tip section being fixed in advance parcel band.But the use of principle gluing point is a kind of special circumstances, usually not only also use offset printing trace when many filter tips (section) when single-filtering mouth (tow).
In order to coating adhesive impression, the nozzle that has the circular open cross section of such as 1.6mm diameter is set, such as utilizes gear pump to be applied by its volume given in advance continuously in glue via this nozzle.Coated colloid amasss and can such as control to control by the rotating speed of gear pump in this case.The glue-spread of roughly (3-8g)/600m bar length of the parcel band for being fixedly used for fixing tobacco and the glue-spread of roughly 10 to the 30g/600m bar length for the parcel band of fixing filter rod is drawn thus according to the volume produced by gear pump, wherein, bar speed (Stranggeschwindigkeit) is roughly 200 to more than 600m/min.But also achieving under special circumstances and have more than 600m/min, the equipment of the bar speed of such as 700m/min or larger, and do not get rid of, also continuing in principle to improve bar speed to reduce manufacturing cost.
The shortcoming of above-described solution is, glue due to the friction on the inwall of nozzle on cross section skewness from nozzle out.Thus and based on the laminar flow produced, plastic emitting speed to be obviously greater than at the center of nozzle opening in the edge section at nozzle opening and to have the parabola shaped trend on cross section.Due in order to produce the offset printing trace having and determine width, must the minimum glue amount determined be coated on the whole width of offset printing trace, and plastic emitting speed is at the center of nozzle opening, and due to above-described problem, forcibly higher than in marginal zone, glue is coated with too high amount compared to the glue amount of each unit are needed for reality at the center of nozzle opening.In addition, wrap up band and to be significantly less than through the time period experienced of edge section that direction of transfer points to of being parallel to of nozzle opening the time period that parcel band experiences through the central section of exit opening due to the toroidal of the exit opening of nozzle.In two kinds of situations, result causes, and is coated with than more glue obvious in edge section at the center of offset printing trace.But it is desirable for offset printing trace in order to have large bonding force in principle and coating adhesive as far as possible equably, wherein, should lower than minimum glue amount given in advance.
Because plastic emitting speed is too high and therefore too high in the glue amount at the center of the exit opening of nozzle, glue mostly penetrates the parcel band of porous at the center of exit opening, is helpless to the bonding of the edge wrapping up band.This effect is also referred to as glue penetration (Leimdurchschlag).Glue penetration is relevant and increase along with it to the porosity of parcel band.Except the undesirable possible changing odor of product, glue penetration also causes undesirable pollution of whole device or equipment and product subsequently.Except reducing except bonding force due to different distributions, further reduce bonding force by glue penetration.
In addition because filter-tip material is compressed consumingly when bar manufactures and carry out drying and be just crosslinked contoured by applying acetate and stablize, therefore filter-tip material also applies higher reset force at bonding time point.For this reason, on parcel band, coating has the hot glue seam of the high bonding force worked immediately.But because hot glue is not age inhibiting, and filter tip is not under any circumstance all around by continuation processing, therefore edge bonding also can alternatively by second, be also referred to as the cold glue seam being parallel to hot glue seam trend supporting seam and stablize.In cigarette machine, wrap up band utilizes pressing force little as far as possible through overheated dividing plate (Heizsteg) in order to the cold glue that hardens stitches, and is hardened by cold baffle (K ü hlsteg) during usually only having hot glue to be sewn on production process in filter tip machine.The optional cold glue seam arranged in filter tip machine is contrary with cigarette manufacture, is hardened when not having heat energy to input.Sizing material superfluous in principle not only adversely can affect the guiding that hardening process also adversely can affect parcel band.
Cold glue impression and hot glue impression are laid in the edge section narrow especially of filter-tip parcel band abreast.Due to edge strip narrow especially, offset printing trace must to apply with the form variations little as far as possible and width given in advance of trend given in advance.
Therefore, filter rod is expensive especially in addition via the problem in the very large design of the bonding existence of two parallel-oriented offset printing traces.
In order to improve bonding force, known from EP1002468A2, offset printing trace applies with the form of foam, and foam is formed in the following way, and namely liquid glue utilizes bubble, especially utilizes inertia bubble or air bubble to carry out displacement.
Summary of the invention
Within this context, task of the present invention is, proposes this type of device a kind of, realizes having the offset printing trace of bonding force large as far as possible when utilizing this device to wrap up the little as far as possible pollution of band and device or surrounding environment at the same time.
In order to solve this task, advise a kind of device with the feature of claim 1.Other preferred improvement project of the present invention is see the description of dependent claims, accompanying drawing and correspondence.
According to basic thought of the present invention, suggestion, the roller of one rotary actuation is set between parcel band and the exit opening of nozzle, from exit opening, glue is out applied on this roller, and glue is directly coated on parcel band by this roller, wherein, the rotation direction of roller is so pointed to, make roller in the face of process coated band side on motion with parcel band motion point on the contrary.
The advantage of the solution advised is, from exit opening glue out on roller first with the thickness of approximately constant by obliterating (verrieben) on constant width.Directly be coated on parcel band by roller after offset printing trace, or directly transported from roller by parcel band.On roller, produce a glue ring at this, and glue is followed continuously via exit opening.This roller with the motion of parcel band reverse direction at coating adhesive impression time be significant especially because offset printing trace thus in fact on parcel band by obliterating.The offset printing trace thus with constant width can realize wrapping up band until the bar speed of 600m/min.By the obliterating of glue on parcel band, can also realize the connection greatly improved formed by fiber and glue, next its result causes the obviously larger bonding force of glue-line.In an experiment bonding force can bring up to thus until bonding force up to now more than 300%.This owing to, glue obviously more efficiently for two layers of bonding parcel band, and produces the superfluous glue of less share thus.Also can be similar to the effect avoiding occurring glue projection (Leimnasen) completely in glue spreading apparatus thus, thus make device less contaminated.But roller is owing to again being wiped clean in the direction of the rotational motion of lifting in residing periphery section from parcel band at roller, thus make device in fact automatically cleaning.
In addition propose, the rotating speed of roller is variable.Pass through advised improvement project, propose a kind of new parameter, the width of offset printing trace can be changed by means of this parameter.Thus can in order to manufacture the product with other size and offset printing trace width easily be matched with new product especially after carrying out specification replacing to equipment, and need not renewal part for this reason.
When this has the diameter of 2 to 12mm when roller and drive with the rotating speed of 1000U/min to 12000U/min, particularly preferred result can be realized, obtain the circumferential speed of 50 to 150m/min thus.
In addition, when the spacing between roller and the exit opening of nozzle is roughly 0.05mm to 0.15mm, uniform especially gluing and high bonding force can be realized.
In addition, can arrange at least two exit openings arranged successively along the axial direction of roller, glue is applied to roller from exit opening.Offset printing trace is widened when can distribute especially uniformly at the same time thus.In addition also two parallel offset printing traces can be applied on parcel band thus.
When roller is by being formed by the axle of electrical motor driven, the present invention can be realized by abnormal cost cheaply.In addition, the device with simple especially project organization has been drawn thus.Because roller need only have the free section for coating adhesive, a unique designing requirement is, axle must can be freely close in a bit of.
In addition advantageously, glue to be coated on roller residing region and glue from roller coat be layed onto region residing wrapping strips band opposite be arranged on roller.Glue is distributed on roller after being coated on roller in the periphery section of roughly 180 degree thus, just applies on parcel band afterwards and transports from parcel band.In fact roller is between parcel band and nozzle.
At this, when glue has the viscosity of at least 180mPas, can be implemented in the improvement aspect particularly preferred result of bonding force relative to the glue-line used in the prior art of glue-line.Full-bodied glue utilizes the higher viscosity more than 180mPas to be no problem with the coating of constant width when direct coating adhesive impression in principle.On parcel band, full-bodied glue is applied via roller by utilizing the solution of advising, obviously can realize the constant width of offset printing trace more simply, although because its high viscosity of glue is still by be coated on the width that first roller is distributed to and determines and to be just applied to afterwards on parcel band.
Can realize the glue-line with sufficiently high bonding force at this, mode is, for the glue amount of the parcel band coating 5g to 40g of every 500m length.
In addition, when the transfer rate of wrapping up band is between 100m/min and 700m/min, the glue-line with particularly preferred bonding force can be realized by solution according to the present invention.
In addition advise, the exit opening that roller is eccentric in nozzle is arranged.Between the exit opening and roller of nozzle, produce larger free chamber in the side of roller wittingly by the arranged off-centre of roller, in this free chamber, first glue be out gathered in glue storage appts, and it is just transported by the rotational motion of roller afterwards.By glue storage appts by glue to the in fact homogenising of the coating on roller, improve the quality of glue-line thus further.According to the difference of the viscosity of glue and the geometry of glue-line, glue storage appts can design greater or lesser by the measurement of the rotating speed of eccentricity, gap width, the glue amount become a mandarin and roller.
At this, roller preferably staggers prejudicially towards the edge of the exit opening of nozzle, and this edge is arranged in downstream about the rotation direction of roller.Glue is applied on roller by the narrow gap between roller and the edge of exit opening from glue reservoir thus, thus the thickness of the offset printing trace be coated on roller is limited to maximum.
In addition, the edge side that rotation direction about roller is arranged in the exit opening in downstream is saliently shaped facing to roller, the gap width be applied on roller at sizing material on residing side between roller and nozzle can be reduced thus further, the quality of the offset printing trace on roller can be improved again thus and therefore also can improve the quality of the glue-line on parcel band.

Referring to preferred embodiment explaining the present invention by accompanying drawing.Wherein:
Fig. 1: show have nozzle and parcel band according to device of the present invention, and

Detailed description of the invention
Visible one according to device of the present invention in FIG, has a nozzle 2 kept regularly relative to machine, and this nozzle has the roller 4 that an exit opening 3 and is arranged in the rotary actuation at this exit opening 3 place.This roller 4 is the end of the axle of drawing from electro-motor 5 in this case, and is driven in rotation along direction of arrow A.Electro-motor 5 keeps regularly relative to machine and the axle therefore can drawn with roller 4(as nozzle 2) together be regarded as fixing.In addition a visible unlimited parcel band 1, its by means of unshowned conveyer along direction of arrow B to be transmitted from 100m/min to 700m/min, preferably with the transfer rate of 600m/min.Roller 4 is arranged between parcel band 1 and the exit opening 3 of nozzle 2, namely arranges oppositely with the following periphery section of roller 4, abuts on parcel band 1 at this periphery section central roll 4.At this, roller 4 or nozzle 2 is also comprised regularly at term, they can utilize pivot center to implement relative to parcel band 1 or very little motion relative to each other during gluing or before gluing, and roller 4 and nozzle 2 are relative to each other and can change tinily relative to the orientation of parcel band 1 and regulate in other words thus.Important being only under the explanation of term " regularly ", offset printing trace moves through the parcel motion of band 1 through roller 4 to the coating on parcel band 1 or the motion relative to nozzle 2 is carried out.Offset printing trace is actual to be transported by the motion of roller 4 by parcel band 1, wherein, and roller 4 or nozzle 2 insignificant for the coating campaign regulating orientation and/or the very little motion during coating adhesive impression to be regarded as offset printing trace.
Roller 4 is driven along direction of arrow A in the drawings clockwise, thus roller 4 is in the section opposite with parcel band 1, or in the region that it abuts on parcel band 1, be in reverse to the direction of transfer motion of parcel band 1.Transported from roller 4 clockwise thus from exit opening 3 glue out of nozzle 2 and utilize with the form of offset printing trace 6 constant width to be applied to parcel band 1.At this, the parcel band 1 for every 500m length applies the glue amount of 5g to 40g.After being coated to by offset printing trace 6 on parcel band 1, roller 4 is again cleaned in the motion wound off from parcel band 1, and this is also by such as under type is visible, because the thickness being in the glue on roller 4 is obviously thinner in this section.Can avoid thus so-called " glue is protruding " that occur on nozzle 2 up to now.
In addition, by the obliterating on parcel band 1, make glue in the width and thickness of offset printing trace Billy with the offset printing trace that uses up to now via the direct coating of nozzle 2 solution achieved by obviously more uniformly coated, thus after the layer of parcel band 1 is bonding, there is the obvious more firmly glue-line with larger bonding force subsequently.Larger bonding force realizes in the following way, namely glue completely for wrap up band 1 fiber between for bonding articulamentum.Create when layer is subsequently bonding thus parcel band 1 mutually bonding layer and between the uniform as far as possible articulamentum of glue composition of embedding.This uniform articulamentum result in the bonding force of raising, because no longer there is the layer only formed by glue with experiential very little bonding force.Use less glue to result in higher bonding force in this case and result in the less pollution of machine.In addition, for following situation, glue-line formed by the cold glue with the layer only formed by glue, and cold glue is hardened through overheated dividing plate subsequently, exists following dangerous, evaporation and form little cavity thus in sizing material when the water in sizing material hardens on hot dividing plate.Afterwards, cavity forms the interruption of glue-line respectively and reduces bonding force, and mode is, glue-line is split under a load in a line that splits extended by cavity.Due to solution according to the present invention, glue-line is controllably applied by special and can avoid the layer only formed by sizing material in glue-line thus, and result can improve bonding force by solution according to the present invention.
Especially can pass through according to solution of the present invention, even if also can realize the uniform especially glue-line of the thickness with substantial constant and the high bonding force remained unchanged when extra high bar speed.This is because, glue-line by be coated on roller 4 before being coated on parcel band 1 first on larger width with constant thickness obliterating, and to be just coated on parcel band 1 by roller 4 afterwards.
The amplification with the roller 4 be arranged in before exit opening 3 of visible nozzle 2 is blocked in fig. 2.Parcel band 1 is turned to tinily in the opposite side of roller 4 and is abutted on roller 4 with very little pretightning force thus.
Nozzle 2 is so shaped on the edge limiting exit opening 3, makes saliently to construct towards roller 4 in the side, edge 7 of its bottom in the drawings.Meanwhile, roller 4 is arranged prejudicially, and that is, the pivot center of roller 4 is arranged in the below of the center M of exit opening 3 with size E.By roller 4 and the arranged off-centre of side, edge 7 of projection being arranged in downstream about the rotation direction A of roller 4, between roller 4 and side, edge 7, form the gap S that has the gap width of 0.05 to 0.15mm.Above the S of gap, form the free chamber of an increase thus, in this free chamber, glue was aggregated in a glue storage appts before being coated on roller 4.Glue is transported by the gap of offset printing trace 10 from glue storage appts by the rotational motion of roller 4 afterwards.The thickness of the offset printing trace 10 that roller 4 applies and/or amount depend on the gap width S in gap at this, this gap width is constant and should is preferentially 0.05 to 0.15mm.
During the rotational motion of the continuation of roller 4, on roller 4, the offset printing trace 10 of coating is applied on the parcel band 1 that moves along contrary direction to form glue-line 6.At this, offset printing trace 10 on parcel band 1, greatly can be improved the quality of glue-line 6 in the width that will maintain and thickness of coating on parcel band 1 by obliterating on one's own initiative thus under the condition applying very little pressure.In the ideal case, the offset printing trace 10 that roller 4 is applied by gap is applied on parcel band 1 completely, thus roller 4 has exposed, glue-free surface after winding off from parcel band 1.At this, the thickness of the offset printing trace 10 that roller applies also is changed by the rotating speed of roller 4, thus offset printing trace 10 and the glue-line 6 be coated on parcel band 1 can come match with the transfer rate of parcel band 1 simply by the change of the rotating speed of roller 4 on thickness and width.
Certifiedly be, under the bar speed of the coated weight of 20g/min and the parcel band 1 of 600m/min, by the direct coating out from nozzle of the offset printing trace when not using roller, the glue-line 6 with 1mm width can be applied, and when identical glue amount, nozzle and bar speed, the glue-line 6 with 2.5mm width can be applied by using roller 4.In addition, obviously wider glue-line 6 has the obviously more constant thickness on width, thus reduces glue penetration and can improve bonding force by utilizing better bonding agent.
The different geometry of visible roller 4 in figure 3.On its shell face, being provided with what arrange regularly at upper graph central roll 4 take circumferential rib as the depression of form, can hold sizing material in these depressions.
There is at the left diagram central roll 4 of bottom rib and the layout depression between the ribs of multiple circumferentially direction trend, thus offset printing trace 10 is transported by nozzle 2 in the thickness distribution given in advance by the shape of roller 4.Based on the thickness distribution of offset printing trace 10, glue-line 6 is coated on parcel band 1 with the district I with less glue thickness of the longitudinal direction trend along parcel band 1 and the district II with larger glue thickness again.Same effect can be realized in the following way, namely offset printing trace 10 is by the corresponding shape of exit opening 3, nozzle 2 compared with Small Distance and/or by selecting to be coated on roller 4 with thickness distribution different on cross section, as visible in the diagram of bottom right from exit opening 3 gel quantity out.
Roller 4 also can be the axle releasably clamped in chuck, thus can by changing with expense little especially the roller 4 that axle uses different size and different geometries.
According to nozzle 2 with the difference of which pitch arrangement, the size of glue storage appts 9 and the gap width between roller 4 and nozzle 2 can be regulated.Except the spacing of nozzle, the rotating speed of roller 4 also can be used as regulating parameter, wherein, glue-line 6 especially regulates by the rotating speed of spacing and roller in the selection of the porosity of viscosity, the transfer rate of wrapping up band 1 and parcel band 1.
Do not avoiding providing advantage in so-called glue projection by the type of glue-line 6 and the impact of use according to solution of the present invention, thus visible reduction spot and the required expense for cleaning equipment.Even if this is also like this especially at the seam of cigarette, the seam of the bonding parcel band 1 with surrounding baccy fiber is bonding.In addition, the glue seepage of glue-line 6 on the parcel band 1 of the more high porosity of filter-tip material can at least be reduced by the present invention.In addition, when glue-line 6 is formed by the cold glue seam hardened on hot dividing plate, the bonding force of glue-line 6 can be improved.
