The specific embodiment
As shown in fig. 1, cylinders of printing press 1 according to the present invention is preferably used as an impression cylinder, it with the blanket cylinder that is associated 2 collaborative works in a printing element 4 of a sheet-feed rotary printing machine.Comprise a basic cylindrical shell 8 in this cylinder 1, in a most preferred embodiment according to the present invention, basic cylindrical shell 8 castings are made, and have cavity 6 and rib 10 on it, and manufactured materials can be a casting pig etc.As shown in Figure 1, cylinders of printing press 1 of the present invention is preferably applied in the printing element 4, and this printing element 4 is positioned at the upstream of a tumbler.This tumbler is briefly with rotating cylinder 14 expressions of inhaling a pawl (not giving label) and a band paper feeding pawl in Fig. 1.Yet, in the same way, also cylinders of printing press of the present invention can be placed between two printing elements of a rotary press as a paper feed roller, the paper 16 that had just printed in previous printing element is being directed transmission by blowing and can not be being besmirched on the peripheral surface 18 of cylinder, as needs, for example in continued operation, this paper 16 can be by air-breathing and picked and cover smoothly on the peripheral surface 18.
As shown in Figure 2, in the cross-sectional view that the basic cylindrical shell 8 of cylinders of printing press 1 of the present invention has amplified, can see having a groove 20 to begin to dig in the basic cylindrical shell 8 from peripheral surface 18, processing method can be, for example, after basic cylindrical shell cast form and roughing, mill out this groove.Groove 20 or sub-air chamber 26 also can be shaped when basic cylindrical shell 8 cast forms together, as needs, carry out machined again and get final product.Groove 20 is used to hold of the present invention blowing/inhale element 22, and a large amount of air flue 24 that has been shaped in this element 22, these air flues 24 lead to the sub-air chamber 26 of the periphery that is positioned at cylinder 1 from the upper surface that blows/inhale element 22.
In the embodiments of the invention shown in Fig. 2, sub-air chamber 26 is that the bottom surface from groove 20 begins the groove that directly inwardly digs out, and its processing method is for example, to mill out in the machining process of basic cylindrical shell 8.
An air blowing or air-breathing source of the gas (not drawing specially) can be led to by a supply air line 28 in sub-air chamber 26, between air blowing or air-breathing source of the gas and sub-air chamber 26 one or more air valves 30 (briefly drawing with the form of a unit in Fig. 1) and a control device 32 can be installed, air valve can adopt existing revolution transfer valve or revolving valve.
As shown in Figure 3, in another embodiment of the present invention, the bottom that element 22 can directly blown/inhale in sub-air chamber 26 is dug a groove and is formed.The structure of sub-air chamber 26 can be, for example, and several millimeters (as 2 millimeters) height, and on the peripheral direction of cylinders of printing press 1, exceed more than 28 millimeters of supply air lines.Possible in addition is, drum shaft to, the below by one or several element 22 can be stretched by sub-air chamber 26, or even by whole cylinder width.In addition, if 26 of sub-air chamber are positioned at a bottom of blowing/inhaling element 22, and this blows/inhale element 22 and be other versions, for example, a kind of loop configuration, then sub-air chamber 26 also can be made other form (as a kind of form of annular groove), like this, each sub-air chamber all can blow or inspiratory airflow by supply air line separately 28 supplies in one group of annular sub-air chamber 26.
In most preferred embodiment of the present invention, the diameter of air flue 24 that is positioned at sub-air chamber 26 tops is more much smaller than the Outside Dimensions of sub-air chamber 26, and for example, this diameter can be in the scope between 0.5 millimeter to 1.5 millimeters.
As shown in Figure 4, the air flue 24 that blows/inhale in the element 22 can also be widened towards the direction of sub-air chamber 26 in its cross section, and for example, at sub-air chamber 26 places, above-mentioned air flue diameter can maximum reach 3 millimeters or be several times as much as the diameter of the other end of air flue 24.When printing cylinder 1 of the present invention was blown operation, this structure can significantly reduce the sensitivity to the fault that causes because of obstruction, and the obstruction of air flue 24 may be that for example, the dust on the paper or other particles enter air flue 24 and cause.
Of the present invention blowing/inhale element 22 preferred employings to make with basic cylindrical shell 8 identical materials, for example adopt casting pig, but also can adopt other pressure-resistant materials, for example aluminium, steel or fiber reinforced plastic etc., and adopt processing method of the present invention and basic cylindrical shell 8 separate machined.Like this, can adopt suitable instrument, as drill bit group, suitable laser processing tool etc., process high-precision air flue 24 in element 22, from making angle, this method has significant advantage.At this on the one hand, can also adopt withstand voltage, thick pore material directly to make, in the manufacture process of material, can process air flue by the method for shaping processing, etch or sintering.Because element 22 is separate machined, therefore when machine component 22, drill bit was fractureed when boring air flue 24, can not damage expensive more basic cylindrical shell 8 yet; And prior art can directly be holed on the outer surface of basic cylindrical shell when processing printed machine cylinder, damages basic cylindrical shell 8 sometimes.In addition, processing method of the present invention can separate machined element 22, therefore can process a set of pieces 22 simultaneously, can save process time greatly like this.
With said method with element 22 and basic cylindrical shell 8 separate machined intact after, said elements 22 is inserted in the groove 20 on the basic cylindrical shell 8, then, basic cylindrical shell 8 can be processed outer surface by suitable surface mill or surperficial turner tool once more with prior art.For element 22 is fixed in the groove 20 of basic cylindrical shell 8, can adopt screw (not shown), bonding or pressing.Because element 22 carries out fine finishining with basic cylindrical shell 8 together, so the upper surface of element 22 can be accurately identical with the outer surface of basic cylindrical shell 8, thereby can not appear at element 22 situations such as outer surface that regional circularity is too poor or element 22 stretches out basic cylindrical shell 8.Therefore, can not be damaged the printing video situation.
At last, will cover one deck film of fabric on the outer surface 18 of basic cylindrical shell 8, this film can adopt forms such as beading cloth, texture chrome coating as shown in EP 0 165 477.Above-mentioned film has covered the zone of each air flue top at least, has a large amount of pore 36 on the film, by these holes, air blowing or inspiratory airflow will be passed through, and this depends on the mode of operation of cylinder 1 of the present invention, as shown in Figure 6.The cross-sectional diameter in hole 36 is more much smaller than air flue 24.Film 34 can be strained on the outer surface 18 that covers basic cylindrical shell 8, or be bonded on the outer surface 18, like this, when cylinder 1 of the present invention is used as impression cylinder in the pressure roller, film 34 can apply uniform thrust on air flue 24 zones of each unit 22, thereby has prevented that air flue 24 from producing impression on the printing video.As shown in Figure 6, film 34 can have a surface texture 38, and in a most preferred embodiment of the present invention, this surface texture 38 comprises the pit that is connected with each other, thus make blow or inspiratory airflow be evenly distributed on the paper 16 that is positioned on the film 34 below.In addition, film 34 preferably is coated with last layer coating to repel printing ink.
As shown in Figure 5, blow/inhale element 22 and preferably be arranged on the outer surface 18 of cylinder 1 with array format, this array can all be covered with at the axial and circumferencial direction of outer surface 18.But also can make array 40 V-shaped distribution or be radial on the outer surface 18 of cylinder 1.For this reason, can be on the axial distribution of array 40, direction of rotation 42 width along cylinder 1 successively decrease, can adopt different width at the specification of the paper that will handle like this, for example for small-sized paper 16a, have only near the center of outer surface 18 of cylinder 1 be positioned at Paper tractor limit 44a to blow/inhale element 22 air-breathing to pick up this paper.On the other hand, for large-scale paper 16b, because it is usually heavier and can be subjected to bigger action of centrifugal force, all blowing on the therefore preferred outer surface 18/inhales element 22 all to start is with to the enough power of blowing or the suction of paper generation.Therefore, paper 16b also is attracted on the outer surface 18 in other zone except its traction limit 44b.
As shown in Figure 5, each air valve in the air valve unit 30 is preferably supplied in element 22 or their the branch gas locellus 26 with mode the blowing/inhaling in each axial row 40 of group and is blown/inspiratory flow, like this, can carry out the air feed operation according to the specification of paper mold that will be processed, make to have only and blow/inhale element 22 by air feed below the paper 16 that is transmitted by cylinder.In this embodiment of the invention, preferably all elements 22 or their sub-air chamber 26 all connect by valve cell 30 and air-breathing or air blowing source of the gas, and valve cell 30 then adopts the control of existing revolution transfer valve and controlled device 32.
Can also use similar mode, pressure roller just by the back or in by the preceding a bit of time, begin to supply gradually along the roll circumference direction to each axial row 40 by control device 32 air-breathing, thereby make the paper of conveying be attracted on the outer surface of cylinder 1 gradually and flatten.Equally, also can on each axial row 40 of blowing/inhaling element 22, blow, thereby paper 16 is separated from outer surface 18 since a predetermined anglec of rotation by the part supply.
Particularly when printing cylinder 1 of the present invention is used as impression cylinder and be positioned at the upstream of a tumbler in a printing element, now know, can supply air-breathing to the element 22 that is positioned at pressure roller and lead on the axial row 40 in the zone between the paper supply center line 46 (Fig. 1) of downstream rotating cylinder 14, and at the traction limit of paper 44a, 44b just be rotated the gripping device of tube on 14 catch before or after in a flash, immediately to being positioned at traction limit 44a, axial row 40 supplies below the 44b are blown, thereby the paper 16 of absorption on the outer surface 18 is separated, and this method has lot of advantages.
