Description

The invention relates to a folding apparatus in a web-fed rotary printing press according to the preamble of claim 1.

In web-fed rotary printing presses, the webs of material to be printed are removed from a paper roll and fed to a folding apparatus after printing in one or more printing units, in which the webs are cut by a cutting device into individual signatures and subsequently folded in the transverse direction by means of a folding blade arranged on a folding blade cylinder ,

In this case, there is a need that the signatures during the cutting process and the subsequent transport to and / or on the folding blade, or a transfer cylinder of the folder, always controlled to ensure that the leading corners of the signatures do not turn over and the folding breaks are arranged exactly at the intended positions.

From the US Pat. No. 5,484,379 It is known in this context to arrange a first cutting cylinder in front of a folding blade cylinder, which has a segmented, spaced cutting knife, which provides the printing material with a plurality of first partial cuts, which are arranged at a distance to each other. The signatures are guided here during the cutting process and the subsequent transport to and on the folding blade by endless circulating conveyor belts, which are passed through the interstices, and which partially wrap around the downstream folding blade. In a second cutting operation, second sub-cuts are introduced into the web by a further cutting cylinder, which carries a correspondingly provided with further interstices cutting blade, which complement the first sections to a continuous cut. The signatures are in this case performed in a corresponding manner by a plurality of further conveyor belts, which are passed through the other intermediate spaces in the second cutting blade, wherein the folding blade as Support element or anvil element for the second cutting blade is used. As a result of the first and second partial cuts introduced successively into the printing material web, there is the problem, apart from the large number of structural components, that the cut edges of the signatures do not run continuously smoothly even after minor deflections of the signatures after the first cutting operation and therefore generally require reworking ,

The document DE19949223 discloses a device for cutting a moving web of material, wherein the device comprises a cutter disposed on a cutting cylinder and a cooperating with these rotary anvil cylinder, wherein a conveyor belt between the cutting cylinder and the anvil element is guided and acts in the cutting operation of the signatures as a counter element for the cutting blade.

Accordingly, it is an object of the present invention to provide a folder in a web-fed rotary printing press which, with a reduced number of components, ensures always controlled guidance of the signatures during the cutting operation as well as during transport through the folder.

This object is achieved by the features of claim 1.

Further features of the invention will become apparent from the dependent claims.

According to the invention, a folding apparatus for folding signatures, which are separated by a cutting device from a current printing material web printed in a web-fed rotary printing machine, comprises a cylinder, in particular folding blade cylinder or transfer cylinder or collecting cylinder, on the peripheral surface thereof - hereinafter referred to as signature transport surface - the signatures Help be promoted by at least one revolving band-shaped transport element. In this case, the cutting device has, in accordance with the invention, a cutting blade arranged on the folding blade cylinder, which cooperates with a rotating or circumferential anvil element, preferably in the form of a cutting blade cylinder. The revolving band-shaped transport element is guided around the rotating anvil element in such a way that the former acts as a support element or counter-pressure element for the cutting blade during the cutting operation of the signatures.

The circulating band-shaped transport element can in this case e.g. be guided around the rotating anvil element directly adjacent to the peripheral surface of the rotating anvil element.

In the same way, however, it is possible for the circulating band-shaped transport element to be guided wholly or partly around the periphery of the anvil element and additionally via deflecting rollers. Particularly advantageous it has been found in this context, when the pulleys are mounted so that - with respect to the center of the folding blade - the revolving band-shaped transport element over an angular range of about 5 ° to 40 ° before the point of interaction of the cutting blade and anvil element is guided fitting the circumference of the folding blade, and the printing material web between the peripheral surface of the folding blade and the transport element over this area is held so to speak sandwich before the cutting process. This results in a strong reduction of caused by the cutting process web vibrations.

In the same way, however, it can be provided if the printing material web runs in substantially tangentially between anvil element and folding blade cylinder,

The invention provides the advantage that the signatures are securely guided even at very high speeds, without the leading corners of the signatures after the cutting process as a result of the resulting wind in a disadvantageous way turn and lead to a paper jam or even damage to the folder. Furthermore, the device according to the invention has the advantage that the cutting edges of the signatures by the use of a cutting device with a over the entire width of the printing material extending cutting blade are inherently straight and smooth, and not - as in the devices of the prior art in which a first and a second partial section are performed sequentially - have stages that arise, for example, the fact that the signatures are not precisely guided by the conveyor belts, for example due to vibrations.

In the preferred embodiment of the invention, the band-shaped transport element is formed as a belt, which is preferably guided in a groove formed on the rotating anvil element, wherein the depth of the groove is slightly smaller than the thickness of the belt. Although in this case preferably not only a single belt, but a plurality of juxtaposed in a known manner juxtaposed belts are used, the invention will be described below for simplicity using the example of a single belt.

According to a first embodiment of the invention, the belt is designed as a toothed belt which, in the regions in which the cutting blade interacts with it during the cutting process, has reinforced sections or inserts, e.g. made of metal or Kevlar, on which the cutting blade is pressed during the cutting process to cut the web therebetween. This results in the advantage that the inner structure, in particular the longitudinal strands for absorbing the tensile forces within the belt, can be maintained if the sections are arranged only on the smooth-surfaced upper side of the toothed belt, and thereby a cost-effective conventional toothed belt can be used, which requires only comparatively minor constructive modifications.

The reinforced portions are preferably each arranged at a distance from one another, which corresponds to the respective section length of the signature, and which increases in the case of a slip between the toothed belt and the peripheral surface of the folding blade by a value corresponding to the width of the resulting gap, the in the course of the rotation of the folding cylinder by the slip between the leading edge of the printing substrate, or a subsequent signature and the trailing edge of a leading signature results.

The reinforced portions are provided in the preferred embodiment of the invention advantageously each with a cutting groove into which the associated cutting blade of the cutting blade cylinder dips during the cutting process. By introducing an additional groove in the reinforced portions of the toothed belt results the advantage that the cut edges of the signatures are formed very precisely and smoothly even with multi-layered signatures.

The toothed belt is further guided with its toothed side about the rotating, preferably designed as a cylinder anvil element and with its flat back around the folding blade, the drive of the toothed belt is preferably carried out by a formed on the rotating anvil element toothing on the anvil element, in which the toothed side the toothed belt engages. This results in the advantage that the toothed belt is moved with a high phase constancy to the anvil element, whereby a very high accuracy in the maintenance of the cut register can be achieved.

In the preferred embodiment of the invention, the toothed belt, or generally the circulating transport element, is moved with a reduced speed with respect to the signature transport surface of the folding blade cylinder. The speed is in this case such that between the cutting blade and the leading edge of the printing material after the cutting process with progressive rotation of the folding blade cylinder, a gap caused by the slip between the signature transport surface of the folding blade and at a slower speed through the timing belt or the circulating transport element moved separated signature results.

By resulting in this way with progressive rotation of the folding blade gap between the cutting element, or the trailing edge of a previous signature and the leading around the periphery leading end of the printing substrate before separating the subsequent signature has the advantage that the leading edge of the circulating transport element held on the peripheral surface of the folding blade cylinder printing material web can be taken before separation of the signature by a leading edge gripper device, which engages through the gap, the leading edge of the printing material. The leading edge gripping device may in this case be a known gripper device, which the front edge or the leading edge of the printing material in an advantageous manner against an inwardly extending gripper support surface presses and clamps. The closing of the gripper takes place here preferably simultaneously or a very short time after the separation of the signature from the printing substrate by the cutting device. As a result, the signature is brought immediately after the closing of the gripper device to the peripheral speed of the folding blade and held in the subsequent known folding in a known manner by the gripper device when the folding blade abuts the signature in the associated jaws of a downstream jaw cylinder.

Only by the inventive slip between signature and peripheral surface of the folding blade results in the device according to the invention, the possibility that the gripper devices find sufficient space to move out of the peripheral surface of the folding blade and to take the leading edge of the printing material in a reliable manner.

The ratio of the speeds of the transport surface of the folding blade and the speed of the circulating band-shaped transport element in the preferred embodiment of the invention corresponds to the quotient of two natural numbers to ensure that the cutting elements on the folding blade cylinder after a complete rotation of the same again coincide with a reinforced portion of the toothed belt. In a corresponding manner, the same applies to the respective length of the transport surface or peripheral surface of the folding blade to the length of the circulating transport element. In this case, the number n associated with the length of the transport surface may, for example, be in the range between 1 and 5 length units and is preferably 3 length units, whereas the number m assigned to the length of the circulating transport element is, for example, in the range between 1 and 3 length units, preferably at 1 unit length. If we are talking about units of length, this means in particular the length of the maximum processable signature format. However, the numbers, as well as the length units can also have other values.

The cutting element may, for example, be arranged fixedly on the folding blade cylinder and be protected by a protective and clamping device made of rubber-elastic material, for example of polyurethane, provided on both sides of the cutting element and projecting radially beyond the tip of the cutting element. This offers the advantage that the protective and clamping device automatically presses the printing substrate during the cutting process against the anvil cylinder, or against the corresponding reinforced portions of the revolving transport element and fixed there.

According to another, underlying the principle of the invention, the cutting element or cutting blade is not fixedly arranged on the folding blade, but moved back in its periphery. This can be done, for example, by a used to drive the folding blade in a known manner control cam and a cam follower, wherein the control cam is arranged fixed to the frame, and the cam follower is coupled to the cutting element, so that it is actuated by the rotation of the folding blade.

According to a further embodiment of the invention, the circulating band-shaped transport element in the direction of rotation of the folding blade is considered another circulating belt-shaped transport element downstream, which advantageously when using a movable back into the periphery of the folding blade cutting element by a conventional, known by folders ago conveyor belt, or a Variety of known in a parallel manner at a distance from each other extending conveyor belts is formed. This results in the advantage that the further circulating transport element can be designed very cost-effectively as a standard component used for a long time in folding apparatus, whereas in this embodiment of the invention the transport element guided around the anvil element is cut through a smooth-walled endless belt over the entire length of cut-resistant material , For example, made of Kevlar or metal or other cut-resistant, but elastic material which is relatively expensive to manufacture. Another advantage that results from this is to see that the length of the first circumferential smooth-walled belt formed from cut-resistant material can be selected comparatively short, whereas the other, formed by a conventional conveyor belt or a plurality of conventional conveyor belts circulating transport element may have a comparatively long length, without the costs thereby in be enlarged accordingly.

The choice of a comparatively short circumferential transport element made of cut-resistant material also has the advantage that it can rotate at a variable lower speed or at a higher speed than the circumferential surface of the folding blade cylinder in order to reduce the size of the gap between the cutting device, or the gap formed by the speed difference To increase or decrease the trailing edge of a leading signature and the leading edge of the substrate web at will. In this embodiment of the invention, the entire circumferential surface of the anvil member is advantageously formed as a cylindrical surface provided with corresponding grooves for the circumferential or cut-resistant belts, which with an advantageously also rubber-elastic material, such. As polyurethane coated, which serves over the entire peripheral surface of the anvil member away as a cutting surface, which cooperates with the cutting element in the areas where the cut-resistant belt of the peripheral edge-shaped transport element do not run.

As shown in FIG. 1, a folding device 1 according to the invention for folding signatures 2, which are separated by a cutting device 4 from a moving printing material web 6, comprises a folding blade cylinder 8, which has a signature transporting surface 10 on which the signatures 2 are based are guided by a circumferential band-shaped transport element 12.

The cutting device 4 hereby comprises a folding blade 14 arranged on the folding blade cylinder 8, and a cooperating with this rotating anvil element 16, preferably in the form of a cylinder shown in Fig. 1, around which the band-shaped transport element is guided in such a way that the band-shaped transport element during the cutting process of the signatures 2 acts as a counter-pressure element or support element for the cutting blade 14, which in turn is supported at the corresponding point of the rotating anvil element 16. The support on the rotating anvil element 16 can in this case be effected, for example, by a groove strip or a cutting rubber 18 received on the anvil element, as shown in FIG. 4.

According to the illustration of FIGS. 3 and 4, at least one groove 20 is formed in the rotating anvil element 16, in which the circulating band-shaped transport element 12 is guided, wherein the depth of the groove 20 is slightly smaller than the thickness of the band-shaped transport element 12. If, according to the preferred embodiment of the invention, a plurality of parallel adjacent belt-shaped transport elements 12 are used, a corresponding number of grooves 20 are arranged at the corresponding distance from each other across the width of the rotating anvil element 16.

The circulating transport element can be formed according to the embodiment of Fig. 2a, 2b and 4 by a toothed belt 22, which is guided with its toothed side around the rotating anvil element 16 and with its flat side around the folding blade 8, and via a toothing 24th is driven in the peripheral surface of the rotating anvil member 16.

As shown in Fig. 5, the toothed belt 22 is provided with reinforced portions or inserts 26 having a cutting groove 27 into which the cutting blade 14 is inserted during the cutting operation. The reinforced portions 26 are arranged at a distance D to each other, which substantially corresponds to the length of the signatures 2 plus the width B of a gap 28 formed between the leading edge 30 of the printing substrate 6 and the cutting blade 14 of the cutting device 4, that the folding blade cylinder 8 moves at a higher peripheral speed than the toothed belt 22.

As can be seen in FIG. 2a, in a first cylinder position, in which the signature 2 is separated from the web, a leading edge gripper 32 is actuated, which passes through the gap 28 and the leading edge 30 of the printing substrate 6, or just emerging or a very short time previously incurred signature 2 takes. The held at the front edge 30 by the leading edge gripper 32 signature is then pushed in a known manner by a folding blade, not shown, in also not shown jaws of a downstream jaw cylinder.

The speeds of folding blade cylinder 8 and belt-shaped transport element 12, or toothed belt 22 are in this case for example selected so that z. B. after a quarter-turn of the cylinder 8, a gap 28 with a size between z. B. 1 cm and 5 cm is formed.

As further shown in FIG. 6, instead of a toothed belt 22, another band-shaped transport element 36 provided with engagement openings 34 may be used, which may be formed, for example, as a metal band or Kevlar band with a cutting groove 27 preferably formed therein, and which does not have corresponding ones shown pin-shaped engaging elements on the rotating anvil element 16 is driven, which engage in the engagement forms 34.

According to another embodiment of the invention shown in Fig. 7, the band-shaped circulating transport element is designed as a made of cut resistant material, preferably smooth-walled belt 38, which is followed by another circulating belt-shaped transport element 40 in the direction of rotation of the folding blade 8. The belt 38 is in this case guided around the rotating anvil element 16 via guide rollers, which are not designated in more detail, with respect to the center of rotation of the folding blade cylinder 8, the circulating belt-shaped transport element 38 over an angular range of about 40 ° before the point of interaction of cutting blade 14 and anvil element 18 on the circumference of the folding blade 8 is guided fitting, and the printing material 6 between the peripheral surface of the folding blade 8th and the transport element 38 is held over this area before the cutting operation.

The imaginary tangential inlet direction of the web is indicated in dashed lines.

The belt 38 in this case runs in the same way as the other circulating transport element 40 preferably with respect to the speed of the signature transport surface 10 of the folding blade 8 reduced speed, thereby in the same manner as in the embodiment of Fig. 2a and 2b, a gap 28 between the leading edge 30 of the material web 6 and the cutting blade 14 is formed, through which a leading edge gripper 32, the leading edge 30 upon further rotation of the cylinder 8 as shown in FIGS. 8a and 8b takes and thereby the signature 2 after the cutting process with the speed of Signature transport surface 10 of the cylinder leads.

In the same way as the toothed belt 22 and the belt 38 is made of cut-resistant material in an associated groove 20 which is formed on the circumference of the rotating anvil member 16.

As can be seen from the illustration of FIG. 11, when a plurality of adjacent belts of cut-resistant material 38 and a plurality of further downstream circulating transport elements are used, these are each arranged offset relative to one another, the leading edge gripping devices 32 advantageously being centered between the downstream further transport elements 40 are arranged at the locations which are in the amount of the belt 38.

Finally, Fig. 9 shows a preferred embodiment of the cutting blade 14, which is laterally provided with a protective and clamping device 42 which consists of rubber-elastic material, for example polyurethane. The protective and clamping device 42 serves as a protection against injury by the cutting blade 14, which preferably fixed to the periphery of the folding blade 8th is attached, and on the other hand ensures that the leading emerging cut edge of the web 6 is urged during the cutting process against the rotating anvil element 16 and against acting as a counter-pressure element or support element circulating band-shaped transport element 12.
