Description

In a machine, transmit the method and the mechanism of a card band

The present invention relates to a development in the field of machine, and especially relate to automation and adhere to a kind of method and the mechanism that card is used, these cards are preferably by flexibility, scraps of paper shape material manufacture, for example make by paper or press board, by a machine, adhere to a paper web, this paper web moves through (rotation) printing equipment, and printing equipment is produced a kind of final products thus, for example a kind of printing, the information products of publication.

Such machine is known, and for example referring to following patent document: US-A 4,351,517 (" Neal "), US-A 5,968,307 (" Siler "), EP-A 0 949 178 (" Siler ") and GB-B 990,140 (BARR).For this purpose, one piece of tape comprises a large amount of cards, these cards are orientated a back at another in the vertical as, be supplied to such machine, and in this machine, these cards are before every web length that is fixed to a repetition that then produces, they are sequentially separated by band one by one, the web length of this repetition forms a page and by (rotation) printing equipment or similar devices (for example advances, the intaglio press of coiled material, offset press, hot glue printing machine or cold glue printing machine), partly as a result of special high operation speed (90000 cards/per hour or higher), these cards in the card band be by a lacerable perforation or other reduction straight line the card band transversely by being connected to each other, thereby make these cards can be easy, rapidly with separated from one another by tearing each other in machine reliably.

After coiled material has advanced by the one or more printing elements in the printing equipment, card is to use machine to be attached on the coiled material, in this printing element, a kind of image, clause or other analogue are for example to use printing-ink to print, and are to be separated into the independent page or leaf that final products use/print before opening at coiled material.

Identical information, image and analogue can be printed on the web length of repetition, but this point is not a kind of requirement.In above clause, term " web length of repetition " is interpreted as that the expression coiled material prepares to be divided into independent sheet/open/page or leaf wittingly subsequently.

A feature is the web length that common card only is fixed to repetition, crosses the sub-fraction of their skin area, usually less than 50%, or even less than 25%, or wittingly less than they skin area about 10%.A kind of hot-melt adhesive, it is to use a kind of installation quantitative nozzle within it to be coated on the card in machine, normally applies before card is separated from one another, this lining cement is generally used for fixedly card to coiled material.Usually, card is to use an adhesive tapes to fix, and this adhesive tapes moves in the vertical, and the time can easily be eliminated by final products afterwards thereby make them.Yet, also might make card in different vertical or horizontal stationkeeping to coiled material, thereby it is smooth reliably that card is remained on the coiled material.

Card is rectangle normally, and is rectangular and less than A4 or A5 specification (for example about 14cm is long).Quality is usually 80 and 500g/m ²Between.The card fixedly quality of the paper web of usefulness is usually less than 150g/m ²

As known, machine has a so-called register drum on its supply limit, by its guide card band (preferably basically without any sliding), so that the card band transmits.The velocity of rotation of register drum is by a control mechanism control of machine, so that can make web length that card passes through the forward movement of machine and repetition by the time speed of advance synchronous, thereby make each card adhere to position substantially the same on the web length of repetition.Should be clear and definite, the control unit of machine is regulated the circumferential velocity of this register drum usually, therefore and the card band speed that is supplied to machine should be markedly inferior to the speed of advance of the web length of the repetition of passing through, because the length of card is considerably shorter than the web length of repetition usually.In addition, between the web length of card band and repetition synchronously and/or the details of the maintenance of a phase relation can be referring to following patent document: EP-A 0 949 178 (Fig. 7 and 8 especially, and relevant explanation), or referring to following handbook: manual dated 4 May 1992for the Electrocard card-sticking machine, model 763, marketed byHurletron, Inc.of Danville, Illinois, United States of America.

According to patent document US-A 4,351,517 (" Neal ") or GB-B 990 140 (" BARR "), for example, register drum can be designed as and has blunt pin, by the radial surface ground of drum barrel projection, and suitably in the register hole mutual action that on the card band, forms in advance.These register holes are circular, and having a diameter is that 3.2mm (1/8inch) and a pitch are 12.7mm (1/2inch), is equivalent to world standard, is used for " tractor feed ".According to patent application US-A 5,968,307 (" Siler "), for example, register drum can be designed as and do not write down pin, does not therefore need here to form register hole in advance on the card band.

An object of the present invention is to provide the load mode of a kind of replacement of card band in machine, use a driven register drum, have pin, these pins are by the radial surface ground projection of register drum.

According to the present invention, reach this purpose and be by, for example the shape of pin designs in such a way, makes them be suitable for making register hole on the card band, preferably have a size significantly less than the register hole of the world standard specification of using so far, preferably narrow in or be shorter than its 1/10.In a remodeling, these pins can be suitable for the card band in the register hole mutual action, these register holes are significantly less than the register hole of the world standard specification of using so far, preferably narrow in or be shorter than its 1/10.Continue in the development at one, these record pins can be suitable for making the register hole of register hole or processing on the card band, the register hole of these processing is arranged on the card band in such a way, a lacerable perforation or other reduction straight line is formed on the card band, preferably vertical upwardly extending at the card band.

Those register holes less than the world standard specification of using so far are construed as expression except above-mentioned points significantly, the comparable shape of a kind of and lacerable perforation, for example (about 1.5mm is long for the perforation in toilet paper or the 80g paper, 0.1mm it is wide, have a pitch 3.0mm), so as to have one can be bursting perforated outward appearance.Should be clear and definite, use has the register hole that is equivalent to tearable through crack hole gauge lattice, and the width of register hole (Here it is material perpendicular to the size in the plane of card working direction in machine) is than 1/10 littler (about 0.1mm is than 3.2mm) of the width of the register hole of world standard specification.

What register hole had is shaped as, for example little slit or otch, and Here it is, and its width is narrow in significantly its length, and for example, its width is preferably less than 5% of its length less than 10% of its length.In a preferred embodiment, the length of register hole is less than about 2mm, and preferably less than about 1mm, and the width of register hole is less than about 0.5mm, preferably less than about 0.2mm.These slits, otch or analogue do not need to extend through the whole thickness of card.

Therefore, the present invention reaches one or more except above-mentioned points following purposes: a kind of more attracting outward appearance that is fixed on the card on the print product; The simpler production of card band does not form register hole in advance because do not need on the card band; Card can more easily be removed by print product; The more failure-free work of machine.

The record pin preferably has ability with cutting, perforation or punching press card band, and for this purpose, these pins can be tip, toothed or blade shape, for example, are rectangular and/or to be observed by the side be leg-of-mutton by top observation.These pins can have one or more cutting edges.In a preferred embodiment, the record pin is to form a wheel, and it is coaxial and have cutting teeth on its radial periphery with register drum, for example, as present use, so that the lacerable perforation of manufacturing on coiled material.This wheel can be made integral body with register drum.Provide these information, the person skilled in the art can easily be developed the record pin of hope, and other details that does not need to provide any this respect subsequently.

Find that surprisingly such pin and register drum synchronously move, a card band can advance in the way you want reliably by machine, separate subsequently, and the position that is attached to the hope on the final products.Can also find that the propulsive effort that such record pin is enough to transmit needs individually is to the card band, and subsequently need be here in the frictional engagement between card band and the register drum, as defined in patent document US-A 5,968,307.

Preferably use a pressure applicator spare to be positioned at the opposite of register drum, thereby the card band is moved in two gaps between the parts, above-mentioned pressure applicator spare is suitable for keeping the card band to be pressed on the record pin.Pressure applicator spare preferably acts on the less level of of width of card band, for example, and less than 25% or 15% of above-mentioned width.Best above-mentioned pressure applicator spare be by a fixed pressure apply the surface form, apply the boots plate such as a pressure, the card band slides along it, and if suitably can have a Frictional Slipping surface, for example comprise polytetrafluoroethylene Teflon .Preferably slidingsurface is the elastic buckling design, for example uses a kind of material that is easy to elastic compression to coat.In a preferred embodiment, thus pressure to apply the surface be brush shapes or ring shape.The function that pressure applicator spare also has is to tear starter and prevent overbalance when tearing as one.This pressure applicator spare not needs higher tensile force so that along can bursting perforated separation card in the card band.Pressure applicator spare preferably acts in the zone of record pin.

The present invention illustrates in greater detail according to an existing preferred exemplary embodiments below, and this embodiment is shown in the following accompanying drawing, and should be clear and definite it does not limit the scope of the invention wittingly, in these accompanying drawings:

Fig. 1 illustrates a lateral plan of the most important parts of a machine;

Fig. 2 illustrates one section top view of a card band;

Fig. 3 illustrates the detail view of Fig. 1.

In each figure, the common direction that the arrow indication is moved.As Fig. 1, shown in 2 and 3, a machine 1 is integrated with in the rotary printing press (not shown; For example, intaglio press, offset press or cold glue printing machine), be used for print newspapers, magazine etc., its position is, make by a storage rotating shaft uncoiling with by the paper web 2 that printing equipment (for example disposing printing cylinder) printed and advance by machine 1 at its route of direction upper edge shown in dotted line and the arrow, cutting to the downstream, bonding and surface treatment station and other station, when arriving machine 1, paper web predetermined patterns of 2 usefulness (impression) always print on a predetermined repeat length, and this repeat length is equivalent to the integral multiple of one page or one page of final products.Printing cards 3 also is supplied to machine 1 with the form of the card 3 of a single file in advance, and the card 3 of this single file has formed a continuous card band 4 (especially referring to Fig. 2), and it advances along the direction shown in the arrow.In band 4, these cards 3 are by horizontal can bursting perforated 10 being connected to each other of trend.In machine 1, after lining cement had been coated to card 3, the preceding guide card 3 in the band 4 was always along can bursting perforated 10 drawing back.And above-mentioned card adheres on the coiled material 2 subsequently.This adhesion is carried out in such a way, makes each repeat length of coiled material 2 adhere to substantially the same position (for example referring to Fig. 2, EP-A 0 949 178) at least.

Band 4 is (not shown)s of being supplied with by a thesaurus, and register hole is not set, band 4 advances by the guide rolls 5,6 of freely rotating and moves into the driven actuating device of a rotation subsequently or the fixing gap between the sliding shoe 8 of register drum 7 and.Register drum 7 has the record pin 9 that is arranged on the radial periphery direction, by the radial surface ground of drum barrel projection and keep a spacing (especially referring to Fig. 3) between them, and these pins sequentially penetrate by band 4 when drum barrel 7 rotates, thereby formation register hole, band 4 is pulled out by warehouse by pin 4, and sliding shoe 8 keep bands 4 to be pressed on the pin 9.Record pin 9 is positioned on the periphery of a square position or wheel, and they and drum barrel 7 are made single-piece.A quantitative nozzle 11 applies lining cement subsequently to the band 4 that carries with driving drum barrel 7.A kind of optional quantitative nozzle 11 of discontinuous lining cement band 13 uses is coated in the zone between longitudinal edge 21 and the tear line 20, and tear line 20 is made by record pin 9, and is parallel to longitudinal edge 21 and a maintenance and an one short distance.

Sliding shoe 8 is at a position and card band 4 mutual actions, if observed by the updrift side of band 4,7 about 80 ° of drum barrels are left with respect to band 4 in this position.This angle A can be bigger or less, and preferably be at least 20 ° or 40 °.Yet boots plate 8 also can cover the whole basically distance that card band 4 contacts with drum barrel 7 and/or record pin 9.

The triangular toothed shape of pin 9, and can in Fig. 3, find out by the side that cutting edge forms.Fig. 3 illustrates card band 4 and is in and leaves the certain distance of register drum 7.In fact card band 4 is to contact in the subregion of circular arc portion A at least with the periphery surface of drum barrel 7.

Card band 4 moves through stacked directing plate 14 mutually subsequently, gap between 15 and advancing subsequently enters a gap of rotating between driven adjusting drum barrel 16 and the belt conveyor 22, belt conveyor 22 moves with card band 4, and (for example compress preceding guide cards 3 in the band 4 cross drum barrel 16 on drum barrel 16 a radial periphery part, at least 10 °), thereby frictionally being locked to, card band 4 discharges drum barrel 16.The speed that discharges the periphery surface of drum barrel 16 is higher than the periphery surface speed that drives drum barrel 7 being adjusted in such cases, and its guarantees there is not or in fact do not have band 4 here and drive drum barrel 7 or regulate slip between the drum barrel 16 (for one or two drum barrel 7, the slip of 16 maximums is 0.1mm, wish to be to the maximum 0.02mm, more wish to be to the maximum 0.01mm), thereby a strong tension is applied on the band at drum barrel 7, in the segmentation between 16, make band provide a paths in bursting perforated place like this, consequently the preceding guide card 3 in band 4 is at drum barrel 7, separate in zone between 16.Must be clear that in this article the drift of the band 4 between drum barrel 7,16 is the twice of card length to the maximum.

Sliding shoe 8 also be used in can bursting perforated 10 in the zone between drum barrel 7 and 16 the tearing of control.Consider by sliding shoe 8 to be applied to pressure on the card band 4, can bursting perforatedly will begin to tear in the positions of band 4 interior low tensile forces.Fig. 2 indicates this position on the Width with respect to the sliding shoe 8 of band 4, thus can be clear and definite, boots plate 8 be positioned at be right after record pin 9 above.

The periphery surface of drum barrel 7 is smooth and hard, and the driving of band 4 is cut little ice.

Move synchronously in order to make advancing of card 3 and coiled material 2, like this card 3 often is fixed to the web length of a repetition, a correct position, machine 1 is included in drum barrel 7, a detector 17 between 16, this detector has an optical sensor 17a and a light-beam generator 17b, and the card 3 that the light beam from light-beam generator 17b is moved through cuts off, and this card 3 is by sensor 17a record.In addition, make the position that to determine the preceding limb of first card 3 of band 4 between drum barrel 7,16 in this way reliably.Detector 1 go back the number of calculating card 3 and control from nozzle 11 quantitatively.

When advancing on the neighboring that the card 3 that separates is driven at it by drum barrel 16, the side that has applied the card 3 of lining cement enters and the contacting of coiled material 2, coiled material 2 advances and applies gap between the roller 24 by drum barrel 16 and pressure that freely rotates, thereby make card 3 adhere to coiled material 2 securely, and the coiled material part of reservation machine 1 and repetition together.

Machine 1 is controlled in such a way, and the periphery surface of drum barrel 16 is moved with identical speed with coiled material 2.For this purpose, the control unit reception is from the information of relevant coiled material 2 speed of printer and speed and its coupling that makes drum barrel 16.The periphery surface speed of drum barrel 7 is controlled by control unit, as a function of the position that is detected the card 3 that device 17 surveys, with the tram that guarantees that card 3 arrives on the coiled materials 2.Should be clear and definite, with the average velociity comparison of drum barrel 7, less for the rapid change of synchronous drum barrel 7, for example, total is 20% of average velociity to the maximum.

In a not shown remodeling, drum barrel 7 is provided with two or more groups record pin 9, these pins are orientated as an axial distance each other, and card band 4 has the register hole 20 of one or more straight-line patterns, and these register holes are arranged in parallel with each other and keep a distance, and are corresponding with each sets of register pins 9, and make, for example, two groups of such pins be positioned at card band 4 longitudinal edge near, the functional reliability of machine 1 is improved.Find that also boots plate 8 or equivalence element only need use at a sets of register pins 9 places.Card band 4 is introduced machine and is also obtained to simplify.

Should be clear and definite, according to above content of separating, perhaps respond above disclosed content, those of ordinary skills can easily provide further change, these changes are according to these knowledge and form a part of the present invention, for example, its acquisition is by deleting and/or replacing above-described or combine with one or more features of one first embodiment by one or more features of its embodiment who extends and/or with one or more features of one second embodiment with equivalent feature.
