Description

The device that on the paper of transmission, mark is alignd with terminated line

The present invention relates on paper, mark be alignd with terminated line.This terminated line can be perforation line or a striping, and it finishes first paper and begins second paper, and this paper is usually expressed as web-like.Mark is visual, as the ink marks or the embossing of printing, perhaps can be functional, as gluing.

Home-use paper is being known in the art.People often wish to decorate these paper by methods such as printings.Printing gives paper with aesthetic feeling.As selection, this paper can also be given the pattern of its aesthetic feeling and can pass through tactile discrimination by embossing.

This paper is normally with continuous form manufacturing, and then is cut into the section length of hope.Being cut into section length can carry out in use, as a slice of being torn from the limit, end at the terminated line place by the user.For this purpose, terminated line generally includes a virtual connection line, as perforation line.As selection, continuous paper can just be cut into section length before using.This scheme often occurs on individual the napkin paper, and it is cut in process of production, is individual napkin paper when the consumer buys.

In the prior art, when this paper transmitted aborning in a continuous manner, it was relatively easy to apply mark in the direction of crossing equipment.But it is just relatively more difficult to apply mark in device orientation, and it is just more difficult particularly mark to be alignd with terminated line.

A method that solves above-mentioned difficulties is to keep between applying the yardage of gauge point with continuous form stroke between the point that applies the virtual connection line on the relative paper of lacking.But this method does not provide possibility in process of production, and it requires undersized equipment, when apply the virtual connection line or apply grid that the necessary template of mark comprises itself big enough cause error interval between mark and the virtual connection line time just can't realize.

Another trial that solves this difficulty is to keep subsequently mark and terminated line to apply or be applied to the relative weak point of haul distance between the point that is cut off into the segmentation paper when point on the continuous form is produced with continuous form respectively.This method is shorter relatively at the segmentation paper that expectation obtains, and is very effective when for example being individual napkin paper.

But what this method obtained in expectation is long relatively paper, during as web-like products such as toilet paper or paper handkerchiefs, just can't use.Its difficulty be since exist on the whole length occur in continuous form between the gauge point that applies and be applied to accumulated error between the perforation line on the paper.For example, if 0.001 inch the error that applies takes place, 1 inch the error that applies will take place when producing the 1000th unit on first unit of continuous form.

Referring to Fig. 1, for example the accumulated error of individual napkin paper of each 12 inches device orientation length is 0.125 inch.On the contrary, prior art is about 0.5 inch in the accumulated error that surpasses on 700 inches the continuous form (as the approximate length of common paper towel roll).This huge accumulated error makes and adopts the paper handkerchief of prior art manufacturing such as web-like is impossible.

When parent roll is used up, when a new parent roll begins, a bigger problem can take place in the prior art.Parent roll be by will be here disclosed equipment and method be transformed into the product of the big volume of a plurality of independently paper.Different parent rolls has different characteristics, and this characteristic can influence paper transmission and passes equipment.For example, when the stretching paper passed equipment, the amount of tension between the different parent rolls often altered a great deal.Because the variation of this specific character, the mark that applies with terminated line also changes.This variation must be considered in process of production.

One of each vertex representation of two figures cuts off line among Fig. 1, and the paper of paper and back cuts off herein becomes independent segmented paper unit.The length of paper handkerchief is long more, and the accumulated error on paper is also big more accordingly.

" unit " used herein is defined as the part of the paper that separates that is supplied to the consumer, for example, and the paper handkerchief of individual napkin paper or monovolume or toilet paper.Obviously, the length of paper handkerchief and toilet paper is more a lot of greatly than the length of individual napkin paper.Certainly, the accumulated error on paper handkerchief and toilet paper will be bigger also, and be one with length different and different proportional amount.

So, when handling short relatively paper unit adoptable method be not enough to handle on long relatively paper, take place apply the mark difficulty.Yardage is defined as and finally represents length to consumer's product in device orientation.For example, the length of individual napkin paper or pad is a napkin paper or the pad length in device orientation.The length of one winding perforation line paper handkerchief is the length at the whole volume of device orientation, promptly from the adhesive spots of nuclear core to the length of end seal.

Therefore, an object of the present invention is to provide the mechanism of the problem of misregistration between the mark that can solve the sheet paper products with longer length cell and the terminated line, is to twine the paper product that shows the consumer with web-like around the nuclear core more specifically.A further object of the invention is when paper is transmitted aborning, to carry out the adjusting of this spacing.

Paper 14 can pass equipment 10 by means of any suitable device transmission.Usually paper 14 is to pull out from equipment 10 under pulling force.Pulling force can impose on paper 14 by reeling around rotating spool.Rotating spool can be columniform and drive with predetermined angle speed motor rotating by one.Exporting about 30 horsepowers direct current synchronous motor when 3000rpm is exactly a suitable motor.Specific preferred motor can obtain from the Reliance electric corporation of Ohio Cleveland.

Also put on the ending limit 18 of mark 30 and paper 14, and roughly be oriented in a second direction, and second direction is also roughly vertical with first direction on the plane of paper 14.Mark 30 and the terminated line 20 spacing relations that form thus between them arranged spaced apart.This spacing relation is also can regulating aborning of being scheduled to.Mark 30 can be artistic pattern and be printed as monochrome or colour.As selection, mark 30 also can be embossing.

Mark 30 preferably is applied on the paper 14 when equipment 10 is passed in paper transmission as described below.Mark 30 can be applied on the paper 14 by the suitable any device that applies mark 30 with predetermined recurrence interval in this field.In a preferred embodiment, mark 30 is printed onto on the paper 14 from the cylinder of a rotation.Rotating cylinder rotates with predetermined angle speed around a central shaft.Suitable printing process well known in the art comprises intaglio printing and flexographic printing.It is open in the patent of announcing on May 25th, 1993 of authorizing the Leopardi II 5,213,037 that mark 30 is applied to suprabasil suitable device 10, and the content of this patent disclosure also at this as a reference.

Printing cylinder 34 or other any being used for can drive the device that mark 30 is applied on the paper 14 by suitable device such as motor.Suitable motor can be direct current synchronous motor, at predetermined angular speed about 25-125 horsepower of output during for 1700-1800rpm.

If wish compacting mark 30 on paper 14, any embossing technology so known in the art all is suitable.Suitable embossing technology comprises the patent US3 that authorizes Wells that those were announced in December 3 nineteen sixty-eight, in 414,459; Open in the patent of announcing with on March 15th, 1994 in the patent of announcing on January 19th, 1971 of authorizing Nystrand 3,556,907 of authorizing McNeil 5,294,475, the content of these patent disclosures also at this as a reference.

In an alternative, mark 30 is applied with functional characteristic can for paper 14, and is not only the characteristic of visible or aesthetic feeling.In such embodiments, mark 30 can comprise glue, and for example it can be used for two-layer paper sticked together and form the paper 14 of a bilayer thickness.As selection, functional mark 30 can be used on the part of paper 14 changing characteristic with respect to another part of paper 14.For example, be used for that bonding nuclear core twines the afterbody of product and the glue around the product can be used on the paper 14, be used for bonding paper 14 the glue that plays the nuclear core that initial line and paper 14 twine too.

As selection, known increase flexibility, wet strength, temporary wet strength, hydrophobicity/hydrophily, or the additives of function that influences any other characteristic of paper 14 can append on it.The patent US5 that authorizes Givens that a kind of device that can manipulate and be suitable for to apply functional mark 30 (as glue) off and on paper 14 was announced on September 1st, 1992, open in 143,776, the content of this patent disclosure also at this as a reference.

Usually the device that applies mark 30 only need have at first direction and applies mark 30 with the spacing relation and apply the ability of mark 30 with the frequency that predetermined recurrence interval produces mark 30.Mark 30 can apply by any suitable system.A suitable system comprises a rotatable drum that drives around central axis.

Except spaced apart and keep the mark 30 that the spacings relation applies with terminated line 20 with preset space length at first direction, mark 30 can also and be put with one or two longitudinal edge 28.All have juxtaposed mark 30 if each plays initial line, ending limit and longitudinal edge 28, just on paper 14, form a frame.The appearance or the function of paper can be determined and strengthen to this frame.

Referring to Fig. 3, terminated line 20 can apply by any device that is suitable for applying terminated line 20 on paper 14.Suitable device also must apply terminated line 20 with the frequency that predetermined recurrence interval produces.Resemble mentioned abovely, terminated line 20 can fully separately become segmenting unit to continuous paper, or the virtual connection line is provided, as perforation line 21.The suitable device that applies terminated line 20 comprises the first direction that is approximately perpendicular to transmission paper 14 and is being approximately perpendicular to the blade that applies terminated line 20 on this direction that it determines an initial line and the ending limit of the paper 14 of back.

The appropriate device that applies terminated line comprises a rotatable blade 36 that rotates around a central shaft with predetermined angle speed on the perforator roller.Certainly, one or more rotatable blades 36 can be driven by common axis, and this is being known in the art.The patent US5 that authorizes people such as Ogg that the rotatable blade 36 that is suitable for applying perforation line 21 on paper 14 was announced on May 9th, 1992, open in 114,771, the content of this patent disclosure also at this as a reference.

If terminated line is to cut off line, it can pass through two juxtaposed rotatable rollers, and a cut-out roller and a bedding roller 48 realize that this also is known in this area.Certainly, even terminated line of the present invention 20 is a perforation line 21, equipment 10 can comprise that still a cut-out roller 46 and a bedding roller 48 cut off adjacent paper, and each paper all has one group of perforation line 21.The preferred embodiment of specific cut-out roller and bedding roller 48 is open in the patent of announcing April 24 nineteen ninety of authorizing people such as McNeil 4,919,351, and the content of this patent disclosure also at this as a reference.

Rotatable blade or other are used for applying terminated line 20 on paper device also can be by any suitable device, as if equally being driven by motor of above describing.If perforation line blade and cut off blade and all be used in the equipment 10, they can be by motor-driven independently separately, or by same motor-driven.

In current equipment 10, adopt two types motor usually.Describe hereinbefore for first type.This type comprises one or more tractions or drive motors, and they give the one or more rotating element angular speed on the equipment 10.The motor of the motor of this first kind than second type is stronger also more coarse on regulating.The motor of the first kind is connected with rotating element by a differential mechanism 50.Usually, because the rotating element of equipment 10 imposes on the relation of the angular speed of paper 14, traction or drive motors also pass equipment 10 to paper 14 transmission.

Differential mechanism 50 comprises that has the driving mechanism of ability of regulating the angular speed of output shaft 52 with at least 0.001% resolution of the reference angle speed of output shaft 52.This resolution preferably remain on output shaft 52 reference angle speed ± 4% scope in.Usually, the angular speed of output shaft 52 is 200-1500rpm.The angular speed that differential mechanism 50 provides is regulated less than 1rpm.

Differential mechanism 50 comprises an output shaft 52 that connects with pivo table member.Output shaft 52 rotates with respect to the shell 54 of differential mechanism 50, and shell 54 seals output shafts 52 and is rotatably mounted output shaft 52.The phase differential gear 50 that is suitable for is the turnover unit of SA30 for the model that the Andantex company of the Wanamassa of New Jersey provides.

Second type motor is a correcting motor, is generally servomotor.The shell 54 of second type motor-driven differential mechanism 50, the angular speed of the angular speed of shell 54 and power shaft 51 stack like this.This be superimposed upon on the output shaft 52 produces one very accurately and angular speed that can fine control.Correcting motor is generally 2-4hp.

Correcting motor can be independent of the angular speed of traction or drive motors and accurately and accurately be adjusted to a specific angular speed.In addition, if the tension variation of paper, or the spacing of any other characteristic changing terminated line 20 and mark 30 relation are when the angular velocity varies of traction or drive motors, correcting motor can compensate when paper 14 is transmitted the equipment of passing 10, and does not interrupt the transmission of paper.Compensation also can be carried out when paper 14 is transmitted the equipment 10 of passing and not interrupt the transmission of paper.

Terminated line 20 and mark 30 can any hope order apply respectively or be applied on the paper.But the terminated line 20 and the latter in the mark 30 that apply or be applied on the paper 14 continue to be concerned by the spacing that the operation that equipment 10 is controlled keeps requiring between them.

For example, mark 30 is applied on the paper.Terminated line 20 is applied on the paper then.If paper 14 existing perforation lines 21 also have the cut-out line, perforation line 21 applies earlier than cutting off line usually.In the above-mentioned system that applies mark 30 earlier, the terminated line 20 that can obtain to require is with respect to the spacing of mark 30, and keeps this spacing by the position of adjusting terminated line 20, rather than by adjusting the position of mark 30.

Equipment 10 can comprise a yardage correcting motor 45.The angular speed of yardage correcting motor 45 control punch device rollers, cut-out roller 46 and bedding roller 48.As fruit product is to twine product as the nuclear core to provide, and as toilet paper or paper handkerchief, yardage correcting motor 45 can also be controlled the angular speed of transposition hexagonal turret and the nuclear core installation function of this capstan head.This capstan head is wound into product on the nuclear core and carries out auxiliary other functions that are wound into the nuclear core, as is assembled on the mandrel, at nuclear core coating glue, cuts off paper, at the end coating end seal glue of paper etc.

Optimum decision system with yardage correcting motor 45 is open in the patent of announcing on August 18th, 1987 of authorizing McNeil 4,687,153, and the content of this patent disclosure also at this as a reference.Differential mechanism 50 is arranged in yardage correcting motor 45 and between the device that applies terminated line 20 on the paper.

Equipment 10 comprises that is also determined a device that is used for applying the device of terminated line 20 or applies the setting position of mark 30 on paper 14, no matter which kind of situation occurs in manufacture process subsequently.The device that is used for determining the position normally one with rotatable blade 36 or other elements, as the position analyzer 38 that printing cylinder 34 connects, this device is controlled according to error signal.

Suitable position analyzer 38 can be determined the position, angle at least 0.1 degree scope.Preferred positions analyzer 38 has 4,096 pulses in revolution.Suitable position analyzer 38 can obtain from the Reliance electric corporation of Ohioan Cleveland, and model is M/N57C360, and usually by driving the motor-driven of pivo table member, signal obtains from this pivo table member.Analyzer can use with analyzer input module (as being M/N57C411 from the model of Reliance electric corporation acquisition).If desired, can replace position analyzer 38 with an encoder, it adopts suitable control logic circuit, and this is being known in the art.

Equipment 10 also comprises the device of the position of the mark 30 of a detection on paper.Preferably determine by the contrast between certification mark 30 and the paper.

Two this devices of detection position 40 should be provided.Preferably two devices are positioned at the opposite side of paper and in the position consistency of the direction of crossing equipment.Each this device is determined the position at the mark 30 of a corresponding side of paper.Relatively oblique distortions is determined in the position of mark 30, corrects the distortion of the direction of the equipment that crosses when needing, and can use device well known in the art, as holds up roller (cocking rolls) or other influence the device of haul distance.For the purpose of the spacing relation that keeps hope discussed above, averaging in two positions of the mark 30 that detects at the opposite side of paper 14, produces error signal and form a position signalling.

Certainly, mark 30 can not provide enough references of relative paper.In this case, alignment mark 31 can be applied on the paper 14 alignedly with mark 30.If an alignment mark 3l is applied on the paper, preferably be applied to the edge of paper.The edge is meant the part of paper 14 at outer ledge, and it removes from the paper 14 that represents to the consumer subsequently.Because this edge does not represent to the consumer, so alignment mark 31 can be to be applicable to the virtually any size and the shape of indicating its position to checkout gear.Alignment mark 31 preferably is printed onto on the paper 14 by being used for the same galley of typographic(al) mark 30.By this way, the mark 31 that applies all is as can be known with respect to the distance of mark 30 or any other part.Therefore, mark 30 is as can be known with respect to the distance of the hope of terminated line 20 equally.The distance of wishing can be 0, and the mark 31 that aligns thus (or part of the detected mark 30 of checkout gear) is consistent with terminated line 20.As selection, alignment mark 31 (or part of the detected mark 30 of checkout gear) can be offset to all directions from terminated line 20.

Equipment 10 can also comprise a signal comparator 44.Signal comparator 44 can subtract each other two input signals and produces an error signal.First input signal of giving signal comparator 44 is the distance between mark 30 (or alignment mark 31) and the terminated line 20.Input signal can provide based on the speed that the paper 14 of equipment 10 is passed in distance between mark 30 and the terminated line 20 and transmission.The appropriate signal comparator is the electric automatic processor module of Reliance (ElectricAuto Processor Module), comprises that analyzer takes the photograph mutually eye and analyzer input card.

Second input signal that offers signal comparator 44 is the position that applies the device of terminated line 20 on paper 14.Signal comparator 44 subtracts each other two input signals and produces an error signal.When error signal surpassed a preset value, equipment 10 was revised.Preset value is the spacing of the expectation between mark 30 (or alignment mark 31) and the terminated line 20.The suitable preset value that runs through whole paper 14 length used in this invention is ± 0.125 inch (gamut is 0.25 inch), and preferred value is ± 0.063 inch (gamut is 0.125 inch).

In order to revise, equipment 10 starts suitable motor, as yardage correcting motor 45.This suitable motor is adjusted the position of terminated line 20 on paper, makes terminated line 20 nearer or farther from mark 30, changes the spacing relation between them thus.This correction takes place when paper 14 passes equipment 10 and does not interrupt transmission.Because this suitable motor is adjustable when rotating with predetermined angular speed, so the correction in this moving is possible.

In an alternative, the device that changes the spacing relation between mark 30 and the terminated line 20 can be to change any device that applies the device of mark 30 and apply the haul distance of the paper 14 between the device of terminated line 20.The haul distance of paper 14 can change by using an idler roller 60, and this roller is as shown in arrow 61 to be moved having a direction perpendicular to the element of device orientation, and preferably at the ad-hoc location of idler roller 60 stroke perpendicular to paper 14.Suitable idler roller 60 can obtain in known tracking system, and can obtain from Fife company and Mount Hope company.As selection, the paper haul distance can be by changing with air injection or other non-contact devices skew knitmesh 11.

Another method that changes the paper haul distance is the length that changes paper 14 in stroke.Make in this way, the pulling force (as passing through traction electric machine) that is applied on the paper 14 changes when paper 14 is applying the device of terminated line 20 and apply between the device of mark 30 transmission.Paper pull can change in whole this part of equipment 10, as known in the art, use driven voller by the position between this device, or realize by the pulling force (for example by the use traction electric machine) that the paper 14 of equipment 10 is passed in continuous increase.

The method of other change mark 30 and the spacing between the terminated line 20 relation comprises that also the angular speed that changes one of device of applying terminated line 20 devices or applying mark 30 gradually or two change.Under the situation of the instant value that provides the error signal of above discussing, this can realize by the phase place of regulating this device as required discontinuously.

Those of ordinary skill in the art will recognize that method that in above-mentioned three kinds of methods any one changes the spacing relation between mark 30 and the terminated line 20 can be taken into account and comes together to change the phase place of terminated line 20 with respect to mark 30 that vice versa.The change of this phase place applies the device of terminated line 20 by change or one or two the phase place that applies in the device of mark 30 realizes.

During operation, paper 14 moves with respect to equipment 10, and preferably equipment 10 keeps static, and pulling paper 14 passes equipment 10 in device orientation.Paper 14 can pass equipment 10 by motor-driven any suitable roller pulling, and this roller is when paper passes equipment 10 and paper 14 friction engagement.For this purpose, traction electric machine is united use with the traction correcting motor usually.

The first step that equipment 10 is carried out preferably applies mark 30 on paper.Mark 30 applies by a rotating printing cylinder 34 with predetermined angle speed, as what use in flexographic printing or intaglio printing.Rotatable printing cylinder 34 preferably be used for transmitting traction electric machine and the traction correcting motor that paper 14 passes equipment 10 and separate drive.Mark 30 can comprise subsequently the alignment mark 31 (registration mark) that removes from the edge of paper.Alignment mark 31 or represent to a bit can discover on consumer's the mark 30 with vision.

Second step that equipment 10 is carried out is certification mark 30 (or alignment mark 31).Detection is based on that the difference of the contrast of mark 30 and background finishes by a photoelectric tube 41.For accurately, photoelectric tube 41 preferably just is arranged in the front of rotatable blade 36.

The 3rd step that equipment 10 is carried out is to apply terminated line 20 on paper.Terminated line 20 is arranged on the paper 14 with the certain spacing relation with mark 30.Spacing first or device orientation on.Terminated line 20 is perforation line 21 preferably, but also can be to cut off line 22.Terminated line 20 preferably is oriented in the direction of the equipment of crossing.

The 4th step that equipment 10 is carried out is the position of determining perforation line 21, or the position of other terminated lines.It is determined by the position of understanding the rotatable blade 36 that applies perforation line 21 on paper 14.The position of rotatable blade 36 provides by the analyzer 38 of determining rotatable blade 36 positions, therefore determines the perforation line 21 that rotatable blade 36 applies out.

Alternate position spike between mark 30 and the perforation line 21 is determined by a signal comparator 44.This difference constitutes an error signal.If difference surpasses a default limit in any direction, just revise.

Correction can be finished by the angular speed of regulating traction correcting motor, yardage correcting motor 45, rotatable blade 36 or rotatable printing cylinder 34.Preferably finish correction by the angular speed of regulating yardage correcting motor 45.45 controls of yardage correcting motor apply the angular speed of the rotatable blade 36 of perforation line 21, and also the angular speed of roller 46 and bedding roller 48 is cut off in control, and the functor in the downstream of equipment 10.

Specifically, correction is preferably finished with respect to the angular speed of the speed of paper by regulating rotatable blade 36.This angular speed increases as required or reduces, and drops within the pre-set limit up to error signal.

In a preferred embodiment, paper 14 according to the present invention represents to the consumer with nuclear core product that twine or web-like.This product is suitable as paper handkerchief, pad etc.
