Definitions
- the invention relates to a retaining device for a in a web-fed rotary printing press running web according to the preamble of claim 1.
- Such a restraint is used to secure the clamps of a web, for example in an emergency to prevent worse from happening.
- FIG. 1 A conventional retention device for a rotary printing press is shown in FIG. 1.
- Two substrate webs (B 1 and B 2) are passed through a pair of draw rollers (15) below the former after they have passed through the former.
- One of the two substrate sub-webs is deflected around a register roller (16) and a diversion roller (17) and brought together with the other substrate sub-web.
- the two merged partial substrate webs then pass through a pair of pull rollers (18), which are followed by a retaining device (19) and a capping device (20).
- a further pair of traction rollers (21) is connected to the cutting device (20), after the passage of which the printing material web is guided over a collecting cylinder (23) with an associated knife cylinder (22), cut and transferred to a folding jaw cylinder (24) and, after folding, onto a paddle wheel (25) is given.
- the printing material web can be cut in the cutting device (20). So that the cut end of the tensioned web cannot snap back, the web is held in a clamped manner by the retaining device (19) at the same time as the cutting.
- the roller designated 19a is permanently driven in accordance with the speed of the folder. With 19b pressure rollers are designated, which are rotatably mounted on the stop pneumatic cylinder (19c).
- the pressure rollers (19b) are set off from the printing material web (B) or from the roller (19a).
- the pressure rollers (19b) are simultaneously positioned by the cylinder (19c) on the printing material web (B) or against the driven roller (19a), so that the printing material web (B) is clamped and simultaneously pulled out of the folder .
- the arrangement formed from the pair of pull rollers (18) and the downstream restraint device (19) takes up considerable installation space and is structurally very complex and therefore expensive.
- EP-0391 246 A2 is a pair of catch rollers with a rotating roller, which in the case of a Web break is movable against another rotating roller, known.
- the runs in normal operation Non-contact web between both rollers.
- At least one of the two rollers has a jacket made of several jacket segments, each on an adjusting device rest so that the jacket segments with error-free web processing by the adjustment device are stable in a retracted inner radial position and if the web breaks to capture the web in each case by an attacking on the adjusting device with the Roller rotating actuating device is moved radially outwards via the adjusting device become.
- a cylinder for a printing press is known from DE-U-91 15 526, in which the lateral surface, for the purpose of assigning different functions, zone by zone in the radial direction can be changed.
- the restraint device which was previously designed as a separate assembly viewed in the web running direction arranged in front of the retaining device pair of drawing rollers moved back.
- pulling and restraining functions are performed by a single person Roll pair met with a first and a second roller running against it.
- the first and the second roller face one another Circumferential surfaces.
- at least one of the two rollers has one or more Circumferential areas facing the or the run-off surfaces of the roller concerned are withdrawn, and therefore to the counter roller and the continuous material web in Normal operation, d. H. in train operation, forms or form a free gap.
- at least one clamping device is the following is also referred to as a restraint, arranged such that it can be clamped the web can be pressed towards the other roller, but in normal operation also does not touch the continuous path.
- first and second peripheral regions of which the first peripheral regions through drainage surfaces and the second circumferential areas through recessed ones Areas are formed within which an influence on the material web in the Normal operation does not take place.
- the clamping device is in this or localize this withdrawn scope report (s) and trigger it if necessary.
- the clamping means can also be used in normal operation be hired, and no time-consuming hiring process is required.
- the recessed peripheral region is preferably in the form of a simple one shallow groove formed by two pull rings, the outer circumferential surfaces of which form the drainage surfaces, is limited.
- these draw rings are spaced so that all common substrate web widths can be promoted and clamped if necessary.
- the retention means in the withdrawn Circumferential area of at least one of the two pull rollers is arranged - this roller is preferably by the Restraint means radially in the withdrawn peripheral area expanded so that the material web is clamped by the expansion will - especially short response times achieved.
- the pull and restraint function is located in the same place the circumferential area in which the restraining means is arranged, only slightly compared to the or Drain surfaces of the roller in question are withdrawn, that is, the free gap to the material web is very desired narrow. A slight radial expansion of the roller is therefore sufficient in the withdrawn circumferential area for safe clamping. The smaller the expansion required, the shorter it is ultimately also the response time if necessary.
- the retaining means is preferably elastically deformable and preferably it is made of an elastically deformable material manufactured.
- the restraining means is advantageously pressed on against its elastic restoring forces, so that an additional return mechanism after expansion is not necessary is. The invention would be feasible, albeit more complex however, even if the restraining device is used again after expansion would have to be returned to its normal position instead of to strive back to the normal position.
- the expansion within a ring strip of the withdrawn Circumferential area is preferably carried out within at least two ring strips spaced apart in the longitudinal direction of the roller.
- the clamping engagement is particularly well defined. Path distortions can be avoided, which makes restarting easier becomes.
- the expansion is due to Applying a pressure fluid causes, so need only small volumes to be printed, which is the brevity of the Response time continues to benefit.
- the expansion becomes mechanical causes, because of this limitation according to the invention the areas to be expanded only moved small masses become.
- the retracted reception area formed at least one recess in which the retaining means or an actuating means for the restraint means is or which is covered by the restraint.
- the retaining means or an actuating means for the restraint means is or which is covered by the restraint.
- the recess or the depressions are covered by a tubular retaining means just spanned and there is a pressurized fluid in the Pressed in depressions so that the tubular retention means locally in the area of the wells, it being preferably annular recesses, expanded becomes.
- the Invention is in or are in the annular recesses Hoses made of an elastomeric material and guided.
- the hoses can be filled with a pressure fluid.
- the outer peripheral surface is such Tubing in or under the outer peripheral surface of the withdrawn Circumferential area of the roller. Will the hose filled, it stretches over the outer peripheral surface of the withdrawn circumferential area.
- the The hose itself forms the restraint.
- the security against leaks or the elastic increases the restoring force one more over this hose or over these hoses tubular casing, as in the first embodiment, curious; excited. In the latter variant, it will Restraining means spanning the annular gap-shaped depressions Tube formed while in the wells arranged hoses the or the actuating means for the represent retention means formed in this way.
- the actuation takes place of the restraining device mechanically.
- an actuating means for the Restraint means added radially displaceable.
- the actuator is preferably an expansion ring, but can basically also be a suitably shaped slider that is moved outwards in the radial direction.
- the actuating means itself can form the restraining means. However, it can be via the or via the actuating means again be a tubular restraint that is locally expanded by the actuating means.
- Each actuator is in turn with a linkage in Connection which is mounted axially displaceably in the roller. A surface of the actuating means facing the roller axis is beveled. The linkage slides on this sloping surface along its actuation and thereby displaces the actuating means in the radial direction. The when using Risks of contamination and pressure fluids Corrosion is avoided with the mechanical solution.
- a particularly preferred fourth embodiment of the invention is an O-ring-shaped restraint made of elastic deformable, preferably full in cross section, material arranged in the recess.
- a pressurized fluid can be injected.
- the O-ring seals the recess from.
- the depression is at its outer peripheral edges advantageously narrowed.
- this makes the O-ring retained safely during printing, the sealing is improved, and it also becomes a stronger swelling of the O-ring achieved in the radial direction.
- the fourth influencing variable is of course the Pressure of the pressure fluid with.
- the restraint is like a tire on a rim the withdrawn peripheral area of the roller.
- several of these become more tire-shaped Retaining means spaced apart along the longitudinal axis of the roller arranged.
- FIG. 2 is a pulling and restraining device according to the invention 26.1, 26.2. 1 in the direction of web travel seen behind the pair of pull rollers 18 and separated from this arranged restraint device 19 is that shown in FIG. 2 Arrangement in the two opposing and the material web B between rollers 26.1 conveying through it and 26.2 integrated.
- Fig. 3 shows in longitudinal section the pull roller 26.2 with integrated Restraint means 9.
- the two outer pull rings serve as traction means 3 with bordering, the two outer edges of the roller body to mark.
- the two pull rings point on the circumference 3 two adjacent ring strip areas 3.1 and 3.2 on.
- the two seen in the longitudinal direction of the roller outer strip areas 3.1 are knurled and form the Drain surfaces with which the roller 26.2 against corresponding Discharge surfaces of the counter roller 26.1 for conveying between them running through both rollers.
- the inner ones Strip areas 3.2 of each pull ring 3 are opposite the outer ones Strip areas 3.1 withdrawn, so that in these areas the web is not touched.
- the two pull rings 3 are seated each firmly on a roll neck of a roll body 2 the Roller 26.2.
- each of the ends Ring grooves 28 a cross feed 14 for a pressure fluid.
- each of the ring grooves 28 is made of a covering 9 sealed with an elastically deformable material.
- the rubber hose 9 can on the roller body 2 shrunk or glued on, so that it is Ring grooves 28 seals.
- the outer peripheral surface of the rubber hose In its normal position, i.e. im not printed state of the annular grooves 28, the outer peripheral surface of the rubber hose at the same height as the withdrawn ones Circumferential surfaces 3.2 of the two outer pull rings 3.
- a recessed, smooth peripheral region 27 is thus created, in which the between the drain surfaces 3.1 of the two Rolls of printing material passing through rollers 26.1 and 26.2 are not touched becomes.
- a pressure fluid preferably air or a hydraulic fluid, feedable.
- the pressure fluid passes through a central, in the longitudinal direction of the bore 13 and of which radially branching cross bores 14 into the through the Ring grooves 28 and the rubber tube 9 formed cavities. Due to the pressure built up, the tube 9 bulges in the area the ring grooves 28 to the outside. In its radial radial widened areas, the hose 9 presses the web against a corresponding counter surface of the counter roller 26.1, whereby the web between the two rollers 26.1. and 26.2 clamped becomes.
- the counter roller 26.1 can be designed in exactly the same way as the roller shown in Fig. 3 26.2. However, it can also be a simply smooth draw roller can be used, preferably one likewise withdrawn circumferential region 27 in the in FIG. 3 has the shape shown.
- a is also activated Pressurized fluid in the formed from the annular grooves 28 and the hose 9 Cavities initiated.
- the hose 9 begins to close stretch and fill the gap between the two rollers 26.1 and 26.2 in places.
- the web is therefore not exclusive between the drain surfaces 3.1 of the two pull rings 3, but also clamped at the contact points with the hose 9.
- the number of contact points can be selected depending on the web width.
- Several pull rings can also be used with the roller 26.2 Drainage areas 3.1 may be provided, with several withdrawn Circumferential areas 27 between two such drainage surfaces 3.1 would be arranged. If the machine has come to a standstill, the pressure is reduced and the hose 9 is drawn up its initial size back. The train will then only be used by the two run-off surfaces 3.1 of the pull ring pair 3 and the Pulling and retaining device is for a new start of the Machine ready.
- each of the tubes is 12 to expand the roller 26.2 via the axial feed 13 and a branch feeder 14 branching from it or else via several star-shaped cross feeds 14 with the Pressure fluid can be filled.
- the cross-sectional shape of the tubes 12 and the internal pressure of these hoses preselected for normal operation 12 are chosen so that the tubes 12 are leading them Fill in the annular groove 28 straight, i.e. they lie with their side walls in normal operation already on the side walls 28.1 and 28.2 of the ring grooves 28, they also lie on the groove bottom in the area of their filling opening and protrude with their outer Circumferential surface up to or close to the outer peripheral surface of the Roller body 2.
- the roller body 2 is again, as in the embodiment 3, spanned by an envelope 9.
- the other constructive details of the exemplary embodiment 4 correspond to those of the embodiment 3.
- Fig. 4 shows the roller 26.2 both in normal operation with a planner outer peripheral surface in the recessed peripheral region 27, namely in the upper part of the longitudinal section shown, as also in the expanded state, in which the 28 embedded tubes 12 have been printed; the latter is indicated in the lower half of the longitudinal section of FIG. 4.
- the envelope 9 as in the exemplary embodiment according to Fig. 3, is applied to the roller body 2 so that the Ring grooves 28 are sealed by them, so is by the double arrangement a double of casing 9 and tubes 12 Security against leaks that can never be completely ruled out.
- the embodiment variant shown in FIG. 4 is suitable is therefore particularly suitable for the hydraulically effected expansion a roller because the hydraulic solution despite many advantages more problematic in terms of leakage than a pneumatic one Solution is.
- FIG. 5 shows a derivative of the exemplary embodiment according to FIG. in contrast, however, a simplified embodiment variant presented the invention.
- embedded hoses open to the outside and are not of a covering 9 covered.
- the embodiment shown in Fig. 6 differs differ from those of FIGS. 3 and 4 by the type of actuation of the restraint, which in turn by a the roller body 2 covering 9 is formed.
- the ring area shaped Widening of the hose 9 is in this embodiment mechanically effected.
- a linkage 11.1 and 11.2 mounted axially displaceably in the roller body 2.
- the Linkage is by a extending in the longitudinal direction of the roller Rod 11.1 and rigidly connected and off the rod 11.1 radially projecting arms 11.2 are formed.

- each of the ring grooves 28 is a radially expandable expansion ring 10 arranged.
- the Ring grooves 28 also slidably mounted corresponding sliders be.
- a surface 10a of each facing the roll longitudinal axis Spreading ring is beveled, i.e. it runs under one Angle to the longitudinal axis of the roller.
- the expansion rings 10 are in the normal position and below the longitudinal axis in the extended position shown.
- the rod 11.1 is cut longitudinally for this purpose, and the two pieces are shown staggered.
- FIG. 3 With regard to the further details of the design variant 6 can refer to the explanations for FIG. 3 insofar as they are not actuating the restraint affect.
- FIG. 7 A further embodiment of the invention is shown in FIG. 7.
- the circumferential depressions 28 are seated here with O-rings 6 an elastically deformable material with a full cross-section.
- the a central bag feed 13 is connected and through the a pressure fluid can be introduced into the recess 28.
- 7.1 and 7.2 show the arrangement of an O-ring 6 in a recess 28 in detail.
- the O-ring 6 in Fig. 7.1 in its normal position and in Fig. 7.2 in the expanded state, i.e. when printing on through the recess 28 and the O-ring 6 formed cavity, shown.
- the O-ring 6 has an elongated, rounded cross-sectional shape on. In the normal position (Fig. 7.1) it fills the Depression 28 as far as possible, i.e. it lies on the side walls 28.1 and 28.2 of the depression 28 and preferably touches still the deepening reason or is even under slight Preload on it.
- the recess 28 is again as essential simply rectangular ring groove. Along its circumferential, mutually facing outer edges is the Well 28 narrows.
- the side walls run outside 28.1 and 28.2 in inclined surfaces 28.5 and 28.6 under training from mutually protruding lip lips 28.3 and 28.4.
- the o-ring 6 is also due to the inclined surfaces 28.5 and 28.6 both lip lips.
- the O-ring 6 In the normal position, the O-ring 6 projects up to at most the outer peripheral surface of the withdrawn peripheral area 27. Preferably it keeps a small distance from this outer peripheral surface, so that touching the continuous web in normal operation is safely prevented.
- the O-ring 6 In the printed state (Fig. 7.2), the O-ring 6 widens elastically on. It swells in its outer area through the two Edge lips 28.3 and 28.4 through to the outside and forms thereby a pear-shaped cross section, the bulbous Part of the recess 28 largely fills. With increasing Pressure in the cavity is the O-ring 6 in its waist area increasingly firm against the sloping surfaces 28.5 and 28.6 pressed. The formation of lip lips 28.3 and 28.4 thus reducing the width of the overflowing O-ring 6 and this increases the radial expansion and it becomes simultaneous one improved with increasing pressure of the pressure fluid Sealing of the printed cavity is achieved.
