Abstract

The cylinder comprises a body with tools round it coupled to a control device and a cam plate tracked by the control device of each tool, and a cover disk (08). The cam plate with peripheral section controlling working movement in cooperation with control device. The cover disk has several sectors (e.g. 12, 13) of different radii.

Description

The invention relates to a cylinder for the processing of flat material according to the preamble of claim 1.

By the DE 38 28 372 A1 It is known to provide on the cover plate in the radial direction adjustable cam. By means of these cams can be formed on the cover plate sections that lock a scanning movement of the tool during scanning by the control lever. By appropriate distribution of the sections on the cover plate, the cover plate can be adapted to the respective production method. Further, cover plates are known which comprise a plurality of partial cover plates and which are rotated relative to each other for switching between production ways by means of motors. In both cases, however, the construction of the cover disc and cylinder is very complex and includes many individual parts. In addition, the changeover between the production methods is complex and time-consuming.

The US 4 094 499 A discloses a cylinder for processing flat material, with a cylinder body rotatable about a cylinder axis, on which controllable tools are arranged. These tools are driven by a cam and a cover disc, these discs have sectors with different radii.

The US 5,305,993 A. discloses a cylinder for processing flat material, comprising a cylinder body rotatable about a cylinder axis, at least one group of a plurality of tools evenly distributed around the circumference of the cylinder body, arranged to perform a working movement with respect to the cylinder body and respectively to a control means for driving the working movement coupled, a stationary cam scanned by the control means of each tool; and a cover plate rotatable coupled to the rotation of the cylinder body and scanned by the control means of each tool, the cylinder having a triple-picking mode of operation.

The invention has for its object to provide a cylinder for the processing of flat material, with a simple conversion of production.

The object is achieved by the features of claim 1.

The advantages achieved by the invention are in particular that the same cover plate without conversion measures or other structural modifications for different ways of producing the cylinder can be used. Different ways of production may be, for example, those in which the cylinder collects one or more but not more than n-1 workpieces from the sheet, preferably paper signatures. Each mode of production of the cylinder is associated with a sector group of the cover disk, the order of sectors, e.g. B. circular sectors, with the first and second radius within the group for the associated mode of production is specific, ie, the working movements according to the mode of production permits or suppressed. When the cylinder is operated in a particular mode of production, the control means passes simultaneously with the working movement controlling portion only sectors of the cover disc of a single selected sector group. If, for example, all sectors have the first radius in one of the sector groups, the same working movement of the tools occurs during operation of the cylinder in the mode of operation of the cylinder determined by this sector group with each revolution of the cylinder.

Since the cover plate is rotatably coupled to the rotation of the cylinder body can be easily switched between two production modes by adjusting a phase between the cover plate and the cylinder body, so that now sectors of the desired production mode associated sector group, the interaction of control device and section to Allow or block taxes on the work movement.

In addition, a wear of the control device is reduced in the cylinder, since the relative speed between the rotating cylinder body and the cover plate is reduced. Namely, by including a plurality of sector groups in the shroud, the number of sectors of the shroud is increased over conventional constructions, and the difference in rotational speeds of the cylinder body and the shroud required for controlling the tool movement with the desired periodicity is significantly reduced. The acceleration, the one the cover disk senses scannable role of the controller at each Inkontaktkommen with the cover plate is thereby reduced. Since the fretting on the roller of the ceiling disc increases disproportionately with the acceleration occurring, the life of the roller is considerably extended.

The pulley for scanning the shroud can be easily mounted to a common control lever with a pulley for sensing the cam. However, then the role of the cam ever loses contact with the cam when the cover disc blocks the working movement. It slows down and needs to be accelerated again. To avoid this, two control levers, one for each roller, may be provided which allow the roller of the cams to remain in contact with the cam even when the cover disc blocks the working movement.

The cover plate can be coupled via a differential gear, such as a planetary gear or a harmonic drive gearbox, to the cylinder body. This gearbox can serve as a drive for the cover plate on the one hand with the balance shaft held. On the other hand, the same transmission can also enable switching between the production modes by turning the balance shaft.

An embodiment of the invention is illustrated in the drawings and will be described in more detail below.

Fig. 1 shows an end portion of a cylinder body 01 with three folding blades 02 (in Fig. 1 two visible). The cylinder body 01 is shown here for the sake of simplicity as a cylinder 01 in a narrow, geometric sense, but it is understood that can deviate from the geometric cylindrical shape in practice, provided that promoted signatures on the lateral surface of the cylinder 01 on a circular or circular sector-shaped path become. In particular, the lateral surface may be constructed from a plurality of mutually adjustable segments. The tools 02, z. B. folding blade 02 are each arranged at a distance of 120 ° to the lateral surface of the cylinder body 01 slots extendable to cross-feed supplied signatures at a (not shown) transfer gap and thereby pass to a cylinder, also not shown. After the transfer, a subsequent signature to be able to load on the cylinder body 01, the folding blades 02 must withdraw into the interior of the cylinder 01. For this purpose, the folding blades 02 are each about in the Fig. 1 from the shell of the cylinder body 01 hidden arms with a shaft 03 fixedly connected, which is in each case pivotally mounted in the two opposite face plates 04 of the cylinder body 01. Spigot 06 connected to the end plates 04 are rotatably mounted in a side frame, not shown. Coaxial with the axle journal 06 shown in the figure, a cam 07 and a cover plate 08 are provided. The cam 07 has substantially the shape of a concentric with the axis of rotation of the cylinder body 01 circular disk, in the section 09, z. B. peripheral surface 09 a peripheral portion 11, z. B. a recess 11 is formed. The cover plate 08 can as from sector 12; 13, z. B. circular sectors 12; 13 be construed.

Each of the three shafts 03 of the cylinder body 01 carries two control levers 16; 17, which together each form a control device for controlling the movement of one of the folding blades 02. For the sake of clarity, the control levers 16; 17 in Fig. 1 only shown on one of the shafts 03. The first control lever 16 carries at its free end a roller 18 which rolls on the peripheral surface 09 of the cam 07. In an analogous manner, the second control lever 17 carries a roller 19, which rolls on the peripheral surface of the cover plate 08. The second control lever 17 is fixedly connected to the shaft 03, while the first control lever 16 is rotatable about the shaft 03.

The two control levers 16; 17 carry on each of the other control lever 16; 17 facing side edge a projection 21 and 22, as in the exploded detail view of the control device of Fig. 2 you can see. Between the two projections 21; 22 is a compression spring 23, which the two projections 21; 22 apart. On the second control lever 17 acts on the shaft 03, a torque of a not shown, for. B. housed in the cylinder body 01 spring, which drives the roller 19 against the peripheral surface of the cover plate 08. In the in Fig. 1 shown position rolls the Roller 18 in the recess 11 and the roller 19 on a first sector 12. When the roller 18 rolls on the peripheral surface 09 while the roller 19 is opposite to a first sector 12, the roller 19 does not touch the cover plate 08, since a contact between the Protrusions 21; 22 and at the same time rolling on the peripheral surface 09 roller 18 of the first control lever 16 prevent this. The roller 18 is during the entire revolution of the cylinder body 01 in contact with the cam plate 07 and is thus rotationally driven evenly. However, when the roller 18 penetrates into the recess 11, this only leads to a movement of the folding blade 02, when at the same time the roller 19 a sector 12 with a small radius of the cover plate 08 is opposite, as in Fig. 1 shown. If this is not the case, the roller 19 loses contact with the cover plate 08 and slows down until it again comes into contact with a sector 13 with a large radius.

Fig. 3 shows in a perspective view analogous to Fig. 2 a simplified control device, in which a single attached to the shaft 03 control lever 17 'two rollers 18'; 19 'for rolling on the cam 07 and the cover plate 08 carries. The control lever 17 'only pivots radially inward when both rollers 18'; 19 'happen at the same time the recess 11 and a sector 12 with a small radius.

Instead of the three folding blades 02 or puncture strips with puncturing needles, grippers or jaws, the cylinder 01 can also be five or seven sections, d. H. have five or seven tools 02, in particular folding blade 02 or puncture strips with puncture needles, grippers or jaws.

Fig. 4 shows a front view of the cover plate 08. This is indeed made in one piece, but as below with reference to the following Fig. 6 is shown, it is divided in terms of their function in first circular sectors 12 with a small radius and second circular sectors 13 with a large radius, which are highlighted in the figures to illustrate the facts. In the cover plate 08 includes each Sector group each twelve individual sectors 12; 13th

Each sector 12; 13 belongs to one of three groups; the group membership is indicated by a symbol "<", "<<" or "<<<" with which each sector 12; 13 in the Fig. 4 is provided. The sectors 12; 13 of the individual sector groups "<";"<<";"<<<" alternate cyclically in the circumferential direction of the cover plate 08, ie between each two sectors 12; 13 of the same sector group "<";"<<";"<<<" is in each case a sector 12; 13 of every other sector group "<";"<<";"<<<" arranged.

All twelve sectors of the group "<" are sectors 12 of small radius. This group "<" is for controlling non-collection operation. If the control device 16, 17 or 17 'coincides with a sector 12 of this group "<" at each pass through the recess 11, it follows the contour of the recess 11, and the folding blades 02 perform the working movement, d. H. They exit at each passing of the transfer gap, not shown, and then retract into the cylinder body 01.

The cam 07 comprises one in cooperation with the control device 16, 17; 17 ', the work movement controlling peripheral portion 11, which, if n is an integer equal to or greater than 2, at most 1 / n of the total circumference of the cam 07 accounts, and a working movement not controlling portion, which makes up the remainder of the total circumference ,

Fig. 6a ) and b) are to illustrate the operation of the cover plate 08 when not collecting the mode of production of the cylinder 01. The rollers 18; 19 revolve curves and cover plate 07; 08 counterclockwise. While the cam plate 07 is fixed, the cover plate 08 rotates coupled to the cylinder body 01 in the same direction with this, however, according to the number 12 of the sectors of each group, by 1/12 slower. In the in Fig. 6a ) shown situation, the roller 18 is about to pass the recess 11. The phase of the cover plate 08 and cam 07 to each other is chosen so that the roller 19 has just entered the angular range of a first sector 12 'of the sector group "<". Therefore, in the further course of the rotation of the cylinder body 01, the roller 18 enters the recess 11, and the associated folding blade 02 extends. During the time in which the roller 18 passes through the recess 11, the roller 19 rolls exclusively on the first sector 12 'from. When the roller 18 reaches the end of the recess 11, the folding blade 02 is retracted again. Immediately after passing through the indentation 11 through the roller 18, the roller 19 has left the first sector 12 'behind, as in FIG Fig. 6b ) you can see. During further rotation of the cylinder body 01, in which the roller 18 rolls on the peripheral surface 09 of the cam 07, the folding blade 02 retracts. If, after a complete revolution of the cylinder 01, the roller 18 again reaches the beginning of the recess 11, the cover disk 08 has rotated so far that the roller 19 is in the angular range of the next sector 12 "of the same sector group" Traversing the indentation 11 therefore rolls off the roller 19 on the first sector 12 ", and the folding blade 02 retracts when the roller 18 plunges into the indentation 11 and again when the roller 18 emerges from the indentation 11. One revolution later, it is the first sector 12 "'within the group"<"subsequent to the first sector 12"' on which the roller 19 rolls when passing the indentation 11 through the roller 18. In each subsequent revolution, it is always one of the sectors marked with "<" in whose angular range the roller 19 is located when the roller 18 passes through the recess 11. Since the sectors indicated by "<" are only first sectors 12 of small radius, the folding blade 02 is extended with each revolution of the cylinder body 01; the cylinder 01 works in the non-collecting mode of production.

In comparison, the show Fig. 6c ) and d) the operation of the cover plate 08 with simply collecting the production mode of the cylinder 01. To get from the non-accumulating production mode to simply collecting production mode, the rotation phase of the cover plate 08 relative to the cam is set so that the in Fig. 6c ) shows situation in which the roller 18 is at the beginning of the recess 11. The roller 19 is now at the height of a second sector 13 'of large radius belonging to the sector group <<<< of the simple-collecting mode of production. On this roll rolls off 19, until the situation of the Fig. 6d ). During the time in which the roller 19 rolls on the second sector 13 ', the roller 18 passes through the recess 11. Because of the large radius of the second sector 13' but the roller 18 can not penetrate into the recess 11, the roller 18 touched the cam 07 in the time of unwinding of the roller 19 on the second sector 13 'not. Thus, the lever for the folding blade 02 is not actuated and this does not go out. One revolution of the cylinder body 01 later rolls off the roller 19 as described above on the sector 12 "following the second sector 13 'within the sector group"<<", but since this is a first sector 12" of small radius, this time, the folding blade 02 extends as described above, when the roller 18 passes through the recess 11. Because the first sector 12 "within the sector group"<<"succeeding sector 13"'has a large radius, the folding blade 02 will not be extended one revolution later, based on the alternating arrangement of first sectors 12 and second sectors 13 within the one can be seen that the folding blade 02 with each revolution of the cylinder body 01 extends alternately once and once does not extend.

From the preceding explanations is now the operation of the cover plate 08 in two-collecting production manner, as shown in the Fig. 6e ) and f) is readily apparent. In Fig. 6e ) is analogous to the above situation just before sweeping the recess 11 through the roller 18 and in Fig. 6f ) immediately after painting over. Between these times, the roller 19 rolls on a second sector 13; ie the folding blade does not stop. Within the sector group "<<<", which corresponds to the double-accumulating mode of production, each first sector 12 is followed by two second sectors 13 in each case. After an extension of the folding blade 02 therefore follow two revolutions of the cylinder body 01, in which the folding blade 02 is not extended; the cylinder 01 operates in the double-accumulating mode of production.

Of course, the cover plate 08 could over the shown sector groups "<";"<<";"<<<<" even more have, z. As a sector group <<<<<<", which has a sector 12 on three sectors 13 to control triple collection operation, etc. Such a cover plate 14 for a folding blade cylinder with four different sector groups"<","<<","<<<"and"<<<<"shows the Fig. 5 , Also with the cover plate 14, the number of sectors of each group is 12.

In the above embodiments, only folding blades 02 were considered as examples of the cylinder body 01 mounted and periodically driven tools. It is understood, however, that the invention in the same way as described above, also on other periodically moving tools such as folding blade, puncture strips with puncturing needles, grippers, jaws, etc. is applicable.

Fig. 7 shows as an example of a cover plate 53 for controlling the working movements of tools other than folding blades 02 a cover plate 53 for controlling grippers of a gripper cylinder. The cover disk has four different sector groups with sectors 12; 13 on. As explained above, the sectors 12 belonging to a same sector group are; 13 is marked with "<", "<<", "<<<" or "<<<<", where the symbols are simultaneously identified by the respective sector group "<", "<<", "<<<" or "<<<<" realized production methods. These grippers move once each time the cylinder 01 rotates to pick up a newly delivered signature, and they move once per one or more revolutions, depending on the production mode selected, to release the signatures. During the release movement, the roller 19 moves over in each case one of the sectors 12 or 13 of the group corresponding to the respectively set production mode. The recording movement is controlled by the roller 19 on one of between each four of the sectors 12; 13 lying lying areas 24, which are added to none of the sector groups and have a small radius as the sectors 12. A cooperating with the cover plate 53 cam has therefore usually next to the recess 11, is controlled by the depending on the mode of production, the release of the signatures, a further indentation, which controls together with the areas 24 recording the signatures.

In Fig. 8 is a transmission for a cylinder 01 of a folder, as it is usually arranged downstream of a web-fed rotary printing machine to see. As tools 02, the cylinder 01 has a plurality of evenly distributed around the circumference of its cylinder body 01 folding blade 02 and beyond groups of several evenly around the circumference of the cylinder body 01 distributed grippers. The cylinder 01 is as in the above DE 38 28 372 A1 described from two in cross-section star-shaped, uniformly driven mutually adjustable segments in the form of a laterally mounted Falzmesserteils with the folding blades and a gripper part with the grippers. The folding blade part has an axle journal 26 and the gripper part has an axle journal 27. The axle journal 27 is hollow and is pierced by the axle journal 26, so that both axle journals 26; 27 are mounted coaxially in a frame 28. On the axle journal 26 is a drive wheel 29 for driving the Falzmesserteils and on the axle journal 27, a drive wheel 31 is fixed for driving the gripper part. The drive wheels are 29; 30 are coaxially arranged side by side and have the same diameter.

A provided for controlling the folding blade cover plate 32 is on a coaxial with the axle journal 26; 27 and fixed to this rotatably mounted in the frame 28 hollow cylinder 37 and is thereby also coaxial with the journal 26; 27 arranged and rotatable about this. One of the cover plate 32 adjacent cam 34 is fixedly connected to the frame 28. By means of the cover plate 32 and the cam 34 and unillustrated control lever, the folding blades are controlled as described above. On one of the cover plate 32 opposite end of the hollow cylinder 37 has a sprocket 38. The sprocket 38 is in engagement with a gear 39 of a differential gear 41, z. As a planetary gear or a harmonic drive gear 41, which is connected via a further gear 42 with the drive wheel 29 of the Falzmesserteils engaged. By means of a balancer shaft 43 of the harmonic drive gear 41, an arbitrary phase position can be set between the ring gear 38 and the drive wheel 29 and thus between the cover disk 32 and the folding blade part.

In the same way as the cover plate 32, a cover plate 33 for controlling the gripper is attached to one end of a hollow cylinder 44, which surrounds the hollow cylinder 37 and is rotatably mounted about this. The cover plate 33 is thus also coaxial with the axle journals 26, 27 and rotatably mounted about them. One of the cover plate 33 adjacent cam 36 is fixedly connected to the frame 28 and serves in the manner described above together with the cover plate 33 for controlling the gripper, wherein the representation of the associated control lever has been omitted. Also, the hollow cylinder 44 has on a cover plate 33 opposite end via a sprocket 46. The sprocket 46 is connected to a gear 47 of a differential gear 48, z. B. a planetary gear or a harmonic drive gear 48 is engaged, which via a gear 49 with the drive wheel 29 is engaged. Via a balance shaft 51 of the harmonic drive transmission 48, an arbitrary phase position between the cover plate 33 and the gripper part is adjustable.

sorgen, wobei s die Zahl der Sektoren 12; 13 pro Sektorengruppe "<"; "<<"; "<<<"; "<<<<" ist, drehen sich die Deckscheiben 32; 33 derart, dass wie oben beschrieben stets nur Sektoren 12; 13 derselben Sektorengruppe "<"; "<<"; "<<<"; "<<<<" zusammen mit den Rollen 18; 19; 18'; 19' der Steuerhebel 16; 17; 17' die Einbuchtungen der Kurvenscheiben 34; 36 passieren.This in Fig. 8 shown gear provides a coupling of the cover plates 32; 33 to a rotation of the folding blade part and the gripper part. These are on the drive wheels 29; 31 driven. Since the harmonic drive gear 41; 48 with the drive wheel 29 of the folding blade part and with the corresponding sprockets 38; 46 are engaged, drives the drive wheel 29 and the cover plates 32; 33 on. Unless the Harmonic Drive gearbox 41; 48 for a gear ratio of $$1:\frac{1-s}{s}\mathrm{or}1:\frac{1+s}{s}$$

By going over the balance shafts 43; 51 and the harmonic drive gears 41; 48, the cover plates 32; 33 is rotated relative to the folding blade part and the gripper part, can be a phase between the cover plates 32; 33 and the respective folding blade part or the gripper part such that only sectors of such a sector group "<"; "<<"; "<<<"; "<<<<" together with the rollers 18; 19; 18 '; 19 ', the control lever 16; 17; 17 ', the indentations of the cams 34; 36, which belongs to the desired mode of production.

An alternative embodiment of the transmission shows Fig. 9 , Unlike in Fig. 8 shown gear in the present case, a further drive wheel 52 is attached to the axle journal 26. With this drive wheel 52 are the harmonic drive gear 41; 48 in engagement, so that the cover plates 32; 33 so to speak indirectly via the drive wheel 52 instead of as in Fig. 8 directly via the drive wheel 29, via which a power flow into the transmission takes place, are operated.

The cylinder body 01 and the cover plate 08 rotate counterclockwise, for example. The control device 16, 17; 17 'is formed, for example, leading.
