Description
The present invention relates to the machine in a tobacco industry, particularly the glue spreading apparatus on a cigarette packer provides the device of fluid glue, this device has the extraction vessel that a glue storage container, is used to prepare a certain amount of glue, and an extraction roller that immerses in the extraction vessel, a feed pipe is with the filling in extraction vessel of the glue in the glue storage container.
Packing machine in the tobacco industry is with some, and for example 20 one group cigarette package becomes parcel or box, perhaps a plurality of parcels is packaged into bigger packing, for example bar or case., fold around packed article (cigarette group, inner wrapping array etc.) for this reason, and linkage section is bondd with a packaging material blank.The required glue that bonds is coated on the packaging material blank by means of an automatic double surface gluer that combines with machine, this automatic double surface gluer have one on blank the coating unit and of glue coated provide the device of glue to this coating unit.
This automatic double surface gluer of one prior art has been shown among Fig. 1.It has a gum box, and the inside has a certain amount of glue deposit.When the glue plane in the groove was lower than a predetermined height, a valve was connected the glue supply from a container that is connected, and glue plane one when reaching predetermined maximum value valve close again at once.One extracts roller immerses gum box, and its periphery dips in last layer glue in groove, and with this layer glue or directly be coated on a blank to be coated or the strip of wrapping material, perhaps transfers on another roller of a coating unit.In to the description of accompanying drawing, also to thoroughly discuss in more detail this device.In FP0492950A1, also point out a kind of similar automatic double surface gluer, do not carry glue but describe there in the gum box that is soaked with an extraction roller.
The shortcoming of this known coating system is when smearing PVA glue by rotation extraction roller coat at least, can form foam after the blink of having operated.This makes the surface of the deposit glue in the gum box increase, thus deposit glue can with air generation strong reaction.Consequently on the glue surface, form one deck epidermis.This has caused illusion for the measured value of the control loading height sensor that glue is carried in groove.Firm glue epidermis makes sensor detect a false loading height.Actual glue plane in the below the epidermis may be well below the height of measuring.Glue supply to the gluing article is hindered, even interrupt fully.Another shortcoming is to carry to gum box on the required valve of glue and can harden on the formation surface.This can cause stopping up valve, thereby and causes operating trouble.What therefore, this device constantly needed to detect and keep in repair expends.Moreover, extract the constantly mobile disperse that also impair glue of roller in groove, so that glue is very fast rotten in the groove, reduced cohesive force.
The basis of task of the present invention is another to be set start described the sort of device.
This task is by according to of the present invention, the described the sort of device of beginning, and applies to solve in conjunction with following retouching: extraction vessel has an overfall, so that discharge superfluous glue from extraction vessel; One overfall is set in extraction vessel, just can on packaging material, smears the glue of being taken away more than extracting roller to the glue that extraction vessel is supplied with.By this means, a part of glue always from extraction vessel the upper surface of glue deposit flow away, particularly, the foam that may form also flows away by overfall.
Device modification of the present invention and favourable expansion have been described in the characteristic of dependent claims.A particularly advantageous development of the present invention is, overfall connects a return duct, and return duct connects a delivery pump, and this pump aspirates in overfall, so that the glue of surplus is taken away from extraction vessel.Because from extraction vessel, take superfluous glue on one's own initiative away, eliminated formed foam on the glue deposit upper surface especially effectively through overfall.This device can be moved very reliably, and need not frequent maintenance.A kind of particularly advantageous modification has been described in another development of the present invention, and the arrival end of return duct is essentially U-shaped structure, as the arrival end of overfall from top immersion extraction vessel.Like this, the overfall structure need not to be installed on the extraction vessel, in addition, can also realize very simply regulating of extraction vessel glue plane, and need not the additional motion sealing.A kind of embodiment of device of the present invention, overfall is configured to an arm, and the base plate by extraction vessel is from following introducing.Like this, overfall just can with the extraction vessel secure bond.Of the present invention another develops into, and from the throughput direction that extracts roller, overfall is arranged on the place ahead of roller in the extraction vessel.Herein, owing to extract the direction of rotation of roller, curling is provided with the foam that has guaranteed herein like this and takes away, thereby guaranteed do not have foam in the glue deposit reliably in this.Be used for the pump that the foam of the glue of surplus and formation aspirates away being preferably a membrane pump from extraction vessel, particularly a kind of membrane pump that has a plurality of chambers, conveying on it and/or return duct are connecting a plurality of glue containers.The advantage of She Zhiing is like this, just can take a plurality of extraction vessels simultaneously into account with a pump.The application of device of the present invention in the tobacco industry packing machine is to provide PVA-glue (polyvinyl acetate glue water) to extraction vessel.
Advantage of the present invention is the formation that has prevented the foam in the glue container of automatic double surface gluer effectively.One overfall is set in extraction vessel, allows when in extraction vessel, carrying glue surplus to occur, so just can between storage container and extraction vessel, realize constant glue circulation.Because foam is removed, the epidermis on the glue can't form, so just gluing on the blank of packaging material reliably.And, can in extraction vessel, keep the glue height consistently, thereby for providing the constant condition that continues by extracting roller extraction glue in simple mode by overfall.To the blank gluing time, but produce extraordinary duplication of production effect.Need not to be provided with feed valve according to device of the present invention, this feed valve is because the surface sclerosis of glue can cause operational failure, so the present invention has also improved the operating reliability of device.Because the glue in the glue storage container is carried by surplus and exchanged at least in part,, therefore eliminated the rotten of glue, i.e. the decline of cohesive force so the constant motion of glue roller also can not destroy the disperse of glue.In addition, glue is carried to extraction vessel from the glue storage, improved delivery reliability by means of a pump.
Explain the present invention now in conjunction with the accompanying drawings.
Fig. 1 is the sketch according to a device of prior art.
Fig. 2 is the sketch according to a device of the present invention.
Figure 1 illustrates a glue spreading apparatus on a tobacco industry packing machine and carry the device of fluid glue.This packing machine is that prior art is known.This device has the extraction vessel 1 of a gum box form, and the glue 2 of deposit is housed in it.The one extraction roller 4 that rotates along arrow 3 directions immerses in the glue 2 of deposit, and dips in the glue 2 of getting one deck deposit on its circumference, and it is directly transferred to this layer glue on the gluing thing, perhaps transfers on another transmission parts of a not shown glue spreading apparatus.In order to set up the constant condition of from deposit, extracting glue, a loading height sensor 6 is set, it acts on a valve 7, by this valve, is controlled from the glue of storage container 8 by the loading height of glue in the extraction vessel 1 and to carry.Like this, the loading height in the extraction vessel 1 keeps constant substantially.When the glue plane in the extraction vessel did not reach a predetermined altitude, valve 7 was opened, and carried out glue and carried, and detected and work as loading height sensor 6, when a upper glue plane that mixes up has in advance reached, then stopped glue and carried.
For this known coating system, when particularly using PVA glue (PVA=polyvinyl acetate copolymer), because the extraction roller 4 that rotates will soon form foam.These foams have strengthened the upper surface of glue, thereby make glue and air kickback.Therefore on the glue upper surface, form one deck epidermis.In this case, loading height sensor 6 also can detect this layer epidermis as the glue upper surface, though the glue horizontal plane has been lower than this epidermis in tank.This glue that may interrupt extracting roller 4 extracts, thereby and gluing product inferior occurs.In addition, because the glue caking also may make storage container 8 stop the glue supply, this can cause the bigger fault of automatic double surface gluer.Like this, automatic double surface gluer just needs constantly monitoring and maintenance.Because in this known device, carrying from the glue of glue storage container 8 is to realize that by gravity glue storage container 8 must be arranged on very eminence of extraction vessel 1 top, flows so that realize enough glue.This fills glue storage 8 again for manpower and has caused difficulty.In addition, extract motion constantly in roller 4 (therefore a spot of) glue in being contained in extraction vessel 1, make the very fast variation of glue, disperse and then the cohesive force of therefore having destroyed glue descend.
In conjunction with Fig. 2 the present invention is described now.The glue spreading apparatus on the packing machine of a tobacco industry shown in the figure provides the device of fluid glue, and is similar with device illustrated in fig. 1, has a glue extraction vessel 1, and the glue 2 of scheduled volume wherein is housed.One goes in glue along the extraction roller 4 of arrow 3 directions rotations.Different with the prior art shown in Fig. 1 is that glue pours into extraction vessel by a pump 9 from glue storage container 11.Glue quantity in the storage container 11 only by a buoyancy switch 12 monitoring shown in the letter among the figure, replenishes with known method if necessary.Pump 9 is carried glue from storage container 11 to extraction vessel 1 by a feed pipe 13.And, make the glue quantity of carrying to extraction vessel 1 from storage container 11 by pump 9 bigger than the glue quantity of from extraction vessel, taking away by extraction roller 4.Therefore pump 9 superfluously is carried glue to extraction vessel 1.But, in order still to keep the glue plane in the extraction vessel 1 constant, being provided with an overfall 14, superfluous glue flows away by this overfall.The U-shaped elongated end 16 of a return duct 17 that is connected with the aspiration end of pump 9 is as overfall.The U-shaped end 16 of return duct and is provided with like this from top immersion extraction vessel 1, makes the loading height of determining glue 2 in the extraction vessel as the opening bend pipe of the U-shaped pipe 16 of overfall 14.Can change filled with water plane in the extraction vessel by moving up or down U-shaped pipe 16.Return duct 17 is connected in the suction side of pump 9, in overfall the foam that produces in superfluous glue and the extraction vessel 1 is aspirated.Because overfall 14 is arranged on the place ahead of the throughput direction top roll that extracts roller 4, the foam that is produced is concentrated especially there, so reliably the glue of foamed is got rid of from extraction vessel by suction, therefore can not hinder the gluing to packaging material.Return duct 17 turns back to the storage container 11 from the pressure end of pump 9.Cleared up in storage container with the glue that superfluous glue aspirates out from extraction vessel 1.
Because by feed pipe 13, glue is carried to extraction vessel 1 in the mode of surplus constantly, produces glue circulation through overfall 14, and this is particularly conducive to the disperse of glue.Upgrade because glue is circulating in extraction vessel, although the glue roller is keeping constantly motion, always the glue in the extraction vessel is in the disperse shape, so the maintenance of the cohesive force of glue is constant, and glue undergoes no deterioration.This also is specially adapted to the packing machine of use PVA glue noted earlier (PVA=polyvinyl acetate).Obviously, for this glue,, can avoid the formation of foam, and therefore the foam that forms can not influence the quality for the treatment of gluing article gluing yet owing on one's own initiative superfluous glue and foam are removed together by pump 9 yet.Owing to when extraction vessel 1 is carried glue, do not need valve, can provide glue to fault-free to extraction vessel according to device of the present invention.
According to the present invention, the pump 9 preferred multi-cavity membrane pumps that adopt, it had both connected feed pipe 13 and had also connected return duct 17.In addition, this glue pump also can connect another automatic double surface gluer.The extraction vessel 18 of a this additional automatic double surface gluer has been shown among Fig. 2.This extraction vessel equally also provides glue by feed pipe 13.In this case, the overfall 14 that is used to accept the superfluous glue that need see off is made of an arm 19.This arm inserts the bottom of extraction vessel 18, and through a return duct 21 and pump 9, then is connected with storage container 11.The superfluous glue that pump 9 will flow away and the foam pump of generation are got back in the storage container.In extraction vessel 18, immerse another and extract roller 22.
At this, for example preferably adopting, the model of Almatec machine manufacturing limited company is the compressed air membrane pump of AD15EEE.
