Description

The rotating printing unit that is used for the tobacco industry machine

Technical field

The present invention relates to typographic(al) mark is coated to the goods of carrying along direction of transfer with predetermined transporting velocity of the tobacco industry and especially pack bar and the method and apparatus on cigarette paper slip or the bar-shaped tobacco product preferably by folder.In addition, the invention still further relates to the machine of the tobacco industry, especially cigarette set frame or filter tip spicing machine.

Background technology

Disclose in the prior art the tobacco industry be used for typographic(al) mark is coated in the printing equipment of packing on the bar.For example, on the cigarette paper slip of cigarette set frame, utilize print roller will print printed words and be imprinted on the cigarette paper slip.In the cigarette set frame, utilize the slivering method to make rod-shaped products such as cigarette, cigarlet, cigar or filter stick etc.By the packing bar, in the cigarette set frame, tobacco rods is rolled, wherein used packing bar has typographic(al) mark or print pattern, and it for example can be cigarette trade mark, trade name or other prompting.

Tobacco product on meaning of the present invention is meant and has or not filter-tipped cigarette and all other bar-shaped tobacco products that their packing bar is through printing, and wherein, trade mark mainly represented in the printing printed words that manifest on goods.The such printing printed words or the marking be the noticeable quality mark of this based article and should cause it is made paying special attention to of required composition and working condition by the packing bar, as the type of used printing ink and state and the conveying of passing through a plurality of rollers before inking thereof, the situation of transmission.

The printing equipment that is installed in the cigarette set frame according to prior art comprises a roller arrangement, wherein, waits to print width of cloth material and guides mobile between roller.For application to printed mark or print pattern, be provided with a so-called print roller, this print roller is synchronous with the width of cloth material that moves continuously.Usually, print roller contacts with a roller platen under these circumstances, and here, the packing bar leads between print roller and roller platen and moves.

But this printing equipment has these defectives, that is, because print roller is rotated when high speed conveying and packaging bar, so printing printed words quality reduces or may not be accepted, as a result, when equipment runs up, on the packing bar, there is the manufacturing of the cigarette bar of printing printed words just seriously to be restricted.

Summary of the invention

Therefore, from prior art, the objective of the invention is to, carrying under the situation of goods at a high speed, print pattern printed to tobacco products and especially pack on bar or the bar form articles, at this, can be under the situation of carrying goods at a high speed application to printed mark perfectly.

This purpose is to realize like this, promptly providing a kind of is coated to the goods of carrying along direction of transfer with predetermined transporting velocity of the tobacco industry with typographic(al) mark and especially packs bar and the method on cigarette paper slip or the clavate tobacco product preferably by folder, wherein, in printing process, reduce relative velocity between folder and goods along direction of transfer.In the process that typographic(al) mark is coated on the goods, produce folder (together) motion on the direction of transfer of carrying goods of print pattern, thus typographic(al) mark under in the together motion process of this folder and goods, printing by folder reliably.Unlike the prior art, material strips to be printed is no longer rolled down on print roller, but this folder is carried on the throughput direction of material strips equally.

The reliable like this printing that is implemented on the goods, promptly folder moves to be close to identical or identical speed with the product transporting velocity along direction of transfer.

Especially like this realized even printing, promptly folder and/or goods are transverse to direction of transfer ground and vertically mobile especially with it, and wherein, folder moves up identical sender with goods.As a result, these two directions of motion are promptly laterally overlapped along throughput direction and its.If folder for example moves perpendicular to direction of transfer ground guiding, then folder is carried out elevating movement simultaneously.

Particularly, folder and/or goods are transverse to direction of transfer ground and vertically implement especially with it to seesaw.Therefore, folder for example returned its original position before printing beginning, thereby made folder after after a while or equally spaced one or more print patterns are coated on the goods.

For implementing this method in the narrow or limited space in machine as far as possible, these goods turn to especially being loop overlapping shape in printing process, thereby make the structure of printing equipment become compact.Being turning to of loop overlapping shape causes through bigger conveying distance.

Especially advantageously, goods are transferred on a rotary body in printing process because goods with the one side promptly not printing surface be attached on the rotary body and allow another side printing.

In addition, folder leads on a rotary body and moves, and therefore, when goods are transferred, has reduced the relative velocity between folder and goods on its rotary body.

Preferably by folder a plurality of typographic(al) marks are printed on the goods, thereby except that brand name, also for example product ID is printed on the packing bar surface, product ID is for example covered by the mounting cardboard on the filter tip spicing machine in gluing process subsequently.In addition, can in the seam region of cigarette, will print printed words and be coated on this surface, so that can determine the authenticity of product.

Also advantageously, folder can be programmed according to the printed data that is used for typographic(al) mark, thereby can be apace changes specification and need not change folder on printing equipment.Therefore, when the specification of cigarette set frame changed, the corresponding data group that is used for new spec must be fed to folder, made the new printing printed words of cigarette specification and was coated onto the packing bar thereby be used for new waiting.

In an improvement project of the present invention, folder is changed after using up its consumptive material, thus the print cartridge that for example can change empty apace.

Also advantageously, regulate folder, thereby allow the corresponding requirement that easily is adapted to printed patterns and paper or other printing operation condition of folder according to printing process.

In addition, this purpose realizes by such device, promptly this device utilizes folder that typographic(al) mark is coated at least one goods of carrying along direction of transfer with predetermined transporting velocity of the tobacco industry and preferably packs bar and especially on cigarette paper slip or the bar-shaped tobacco product, the improvement of this device is, can make folder mobile like this along the goods direction of transfer in printing process, promptly reduce the relative velocity between folder and the goods.

Stipulated that for this reason folder can move to be close to identical or identical speed with the goods transporting velocity along direction of transfer.

Particularly, folder and/or goods can be transverse to the direction of transfer ground and are especially vertically moved with direction of transfer.

In order to carry out elevating movement in the process of application to printed figure, folder and/or goods can and especially vertically seesaw with it transverse to direction of transfer ground.

Cigarette set frame shown in Figure 1 is only made a cigarette bar, thereby what relate at this is the single current machine of the tobacco industry.In this case, only a width of cloth cigarette paper slip is printed by printing equipment 23 of the present invention correspondingly.

In the printing equipment shown in Fig. 2 a-2c 230, for two bar machines, typographic(al) mark under seal on the two web materials bars 210.1,210.2.Certainly also can only print a material strips.

Fig. 2 a-2c shows the different perspective views of printing equipment 230.

Two material strips 210.1,210.2 are parallel and lead by two

guide rollers

50,51 side by side, thus make material strips 210.1,210.2 be attached to swing roller body 60 around and clad ratio very the highland on barrel 60.Guide roller 51 is disposed on the support arm 52, thereby material strips 210.1,210.2 is by tensionings well and be not attached on the outer surface of barrel 60 with not playing pleat.

Around barrel 60, print head 70 is arranged on the rotary body 71 with constant spacing.Rotary body 71 rotates on the direction identical with barrel 60.In the rotary course of barrel 60 and rotary body 71, print head 70 moves perpendicular to direction of rotation, thereby in the elevating movement of print head 70 typographic(al) mark is printed on the material strips 210.1,210.2.Rotate in the process of a whole circle at rotary body 71, print head 70 has been finished whole elevating movement with seesawing.In the process of seesawing, typographic(al) mark is printed on the material strips 210.1,210.2 fully.

For example can be with ink jet-print head as print head, wherein, used ink especially meets national standard or tobacco regulations.Flow well in order to ensure ink, special pressure through overregulating is applied on the ink in the print cartridge container, and this pressure resists the centrifugal force relevant with rotating speed.For this reason, between atmosphere and ink, there is film.

The present invention has stipulated, the rotary speed of print head 70 on rotary body 71 and material strips 210.1,210.2 or the rotary speed of transporting velocity and barrel 60 are identical, like this, between material strips 210.1,210.2 and corresponding print head 70, just there is not relative velocity.For this reason, also can guarantee carry at a high speed material strips printed reliably in 210.1,210.2 o'clock under typographic(al) mark.

The elevating movement of print head 70 causes the transfer path overtaking each other of material strips 210.1,210.2 and print head 70, because print head 70 is below its reversal point process material strips 210.1,210.2.

After material strips 210.1,210.2 was completed for printing, two material strips 210.1,210.2 were flowed to flow of tobacco on double-current cigarette set frame respectively by guide roller 53.

Utilize the horizontal line of expression in accordance with regulations on the material strips 210.1,210.2 to represent the length of Dan Zhichang cigarette rod.

Typographic(al) mark is applied to after a while on the mouth side end of material strips 210.1,210.2 of the Dan Zhichang tobacco rods that forms.For this reason, mirror-inverted ground is printed on the typographic(al) mark that adjoins each other on the cut-out point subsequently of two long tobacco rods.Print head 70 have for this reason two side by side ink dot.

In Fig. 3 a, 3b, schematically illustrate the front view and the side view of the printing equipment 23 that is used for single width material strips 21.With the embodiment of Fig. 2 a-2c similarly, material strips 21 by

guide roller

50,51 and 53 big wrap angle ground on the outer surface of barrel 60.Printing process carries out transverse to direction of transfer, wherein, owing to use a plurality of print heads 70 simultaneously, print pattern has been coated to the time lengthening on corresponding a plurality of plume.

Within the scope of the invention, also the inside of printhead arrangement at barrel 60 so just can be coated onto typographic(al) mark on the material strips internally.In this case, just short by the stroke that print head is finished, because this moment only need cover printing zone and paper is looped around on the outer surface of barrel 60 outside.

In Fig. 3 a, show the different operating zone of the print head in its rotation and elevating movement process when circle is put in order in rotation one with Roman number.In area I, print head moves in the nearby guiding of material strips 21, thereby does not print in this zone.In area I I, travel forward perpendicular to shown in plane earth carry out and print head 70 in the other guiding process of material strips side.Then, in area I II, keep vertically from shown under the situation of the direction of motion of coming out the plane, material strips 21 is printed.From area I II during to area I V transition, print head arrives terminal point and the turning point (referring to Fig. 3 b) of its total kilometres H.In area I V, print head retreats then, wherein, equally cigarette paper 21 is printed in area I V.In regional V, print head returns.

Fig. 4 a, 4b there is shown another printing equipment 23 of the present invention at front view and side-looking, and wherein,

roller

51,52 is implemented turning to of cigarette paper slip 21 by a bearing 54.In printing equipment 23, print head 70 has five operating position I-V.

Except applying also colored print pattern, other the information or the anti-counterfeiting information of relevant product authenticity under can also printing.

Fig. 5 schematically illustrates a part of cigarette paper slip 21, and its length is identical with the length of two tobacco rod.In the territory, mouth lateral areas of the tobacco rod that forms after a while, represent printable area with hacures.Dotted line 121 has provided the position on the cut-out limit subsequently of tobacco rod once more.

Because print head 70 has printing width DB, so can print to whole dashed region.Especially to the overlapping region of mounting cardboard and tobacco rod be illustrated.This zone is by reference marker 122 expressions.Because mounting cardboard is around tie point, the printing information of relevant cigarette or manufacturing type etc. be can't see.The information of other relevant authenticity or quality assurance can by print head 70 be imprinted on the tobacco rod seam near.This zone is by reference marker 123 expressions.
