Definitions

  • the invention relates to a device and a method for the further processing of successive, sequentially printed printed sheets.
  • the device has a conveyor for transporting the printed sheets in a conveying direction, a folding table arranged in a downstream area of the conveyor for receiving the printed sheets, a folding blade arranged vertically at a distance from the folding table, a pair of folding rollers arranged on a side of the folding blade opposite the folding blade with a pair of folding rollers formed in between Folding roller gap, at least one hold-down device arranged above the folding table and in its upstream area for pressing down a rear edge of a printing sheet to be positioned on the folding table in the direction of the folding table, with a leading edge of a subsequent printing sheet being fed in at a higher level than the rear edge of the printing sheet positioned on the folding table, and a machine control that is operatively connected to the folding blade and the at least one hold-down device.
  • the successive, sequentially printed printed sheets are transported from the conveyor in the conveying direction to the folding table arranged in the downstream area of the conveyor and picked up there by the latter, with the folding blade vertically spaced from the folding table and the folding blade arranged on a side of the folding table opposite the folding blade.
  • Pair of rollers interact with the folding roller gap formed in between for folding the printed sheets and wherein the rear edge of a leading sheet to be positioned on the folding table is pressed in the direction of the folding table by means of the at least one hold-down device and the leading edge of the subsequent printing sheet is positioned opposite the rear edge of the leading sheet on the folding table Printing sheet is fed increased and the hold-down device and the folding blade are controlled by a machine control.
  • the sequentially printed printed sheets can be unfolded and / or folded printed sheets which are fed inline, that is to say directly or indirectly following a digital printing machine.
  • the supply is also possible offline, i.e. starting from an intermediately stored, sequentially printed material web, from which printed sheets are then separated and then possibly folded, or from an intermediate store with unfolded and / or folded printed sheets.
  • the print image is transferred directly from a computer to the printing machine without the use of static printing forms.
  • the material web can be printed in the specified order of the finished printed product, i.e. sequentially, depending on the intended folding scheme. In this way, relatively small numbers up to a single printed product can be realized.
  • conventional printing processes such as offset printing, there are very often successive printed sheets with different properties, such as the imprint itself, the number of printed pages per printed sheet and its respective format.
  • the transport speed of the material web, which has meanwhile been separated from the material web, or that in the digital printing machine individually printed sheets can be reduced by folding one or more times with known longitudinal and / or transverse folding devices.
  • the folding facilitates the careful further processing of the printed sheets, but each folding process potentially leads to an undesirable, larger number of blank pages. This can be avoided by using previously unfolded printed sheets.
  • this increases the transport speed, which, depending on the further processing devices used, results in a high number of cycles and in turn makes gentle further processing more difficult and can lead to quality problems.
  • a device and a method for inline further processing of a paper web sequentially printed by a digital printing machine are known.
  • the printed paper web first passes through a perforating and cutting station.
  • the printed sheets separated there are individually folded once or several times with cross and longitudinal folding devices. After folding, the printed sheets, which later form a common book block, are brought together like scales in a collating device before they are stacked and glued to form a book block in an adjoining stacking device.
  • the book blocks are then transported for further processing.
  • the EP2502862 A1 discloses an apparatus and a method for processing printed sheets with different formats, which were also previously disclosed by have been severed from a web of material printed in a digital printing machine.
  • the device has at least two collecting drums arranged one above the other for successive printed sheets with different formats.
  • downstream of the collecting drums for example by merging two printed sheets of different formats with a third printed sheet, a partial stack of three printed sheets is created, which can then be connected to another partial stack to form a printed product.
  • the partial stacks can first be longitudinally and / or transversely folded downstream of their formation.
  • the transport speed of the partial stacks can advantageously be reduced in this solution in the downstream area of the print processing device.
  • this requires a relatively complex drive of the two collecting cylinders, for example with a coupling gear or two separate drives that are to be coordinated with one another. A reduction in the number of blank pages is not disclosed.
  • the device has a compressed air device connected to a compressed air source and a control unit with a plurality of outlet openings for compressed air.
  • the leading printed sheet In order to avoid a collision between the trailing edge of a leading printed sheet and the leading edge of a trailing printed sheet during longitudinal folding, the leading printed sheet must always be conveyed out of the folding rollers or below the level of the folding table before the trailing printed sheet can be fed in. Even with these solutions, however, only successive individual printed sheets can be folded.
  • a folding machine with a knife folding station for folding successive, individual printed sheets with at least one lowerable and liftable folding blade and a pair of folding rollers arranged below the folding blade are known.
  • the folding sword has a mechanical sword blade and a pneumatic sword blade arranged immediately upstream and in extension thereof, the latter having at least one nozzle for generating blown air.
  • a downstream mechanical stop for braking the front edge of the printed sheet introduced into the knife folding station, an upstream pneumatic hold-down device for the rear edge of this printed sheet and a further upstream guide element for lifting a subsequent printed sheet when it enters the knife folding station are arranged in the folding machine.
  • the printed sheets lie on rotating conveyor belts and are transported with them through the folding machine.
  • the knife folding station When the folding machine is in operation, the knife folding station is fed one after the other according to the pending production orders, and through the interaction of the folding blade with the folding rollers, they are each individually longitudinally folded. The printed sheets folded in this way are finally conveyed downwards for further processing. Due to the two-part folding blade with the pneumatic sword blade arranged in the upstream area, a subsequent printed sheet can be fed to the knife folding station without the risk of colliding with the folding blade when the previous printed sheet is being folded and is still partially on the conveyor belts. This means that either a higher folding performance can be achieved with the same transport speed or the transport speed can be reduced with the same folding performance.
  • a hold-down force is applied to the trailing edge of the preceding printed sheet by means of the pneumatic hold-down device.
  • the leading edge of the following printed sheet is raised by means of the guide element. The combination of holding down and lifting can prevent these two printed sheets from colliding.
  • the air pulse of the pneumatic hold-down in combination with conveyor belt air on both sides and above the folding table, with pneumatic hold-down elements or in combination with corresponding mechanical hold-down elements, ensures that the printed sheet is pressed against the conveyor belts by means of friction, recording their speed and thus being transported to the stop in a defined manner.
  • this folding machine is only intended for relatively low transport speeds. Further increases in performance are therefore hardly possible.
  • the stop is only suitable for low transport speeds because the printed sheet hitting it could be damaged and / or jump back from the stop at a high transport speed.
  • this folding machine is only suitable for folding successive, individual printed sheets.
  • the EP3002240 A1 and the EP3002241 A1 each relate to a device for braking and positioning a printed sheet, for example, printed by means of a digital printing machine, in a processing machine and a method for operating such a device.
  • a mechanical folding knife is used here, to which each printed sheet is fed in the same plane in which it is positioned before the folding process.
  • the previous print sheet In order to be able to position a subsequent print sheet on the folding table, the previous print sheet must be withdrawn from the folding table so far that its trailing ends are below the feed level of the subsequent print sheet.
  • the object of the invention was therefore to provide a simple and inexpensive device and a corresponding method for further processing of printed sheets sequentially printed by means of a digital printing machine, wherein the transport speed of the printed sheets can be reduced and yet improved performance can be achieved.
  • careful further processing of the printed sheets should be made possible, thus avoiding quality problems and achieving a potential reduction in the number of blank pages in the finished printed product.
  • the at least one hold-down device of the device according to the invention has at least one mechanical braking element for this printed sheet which acts on the upper side of the rear edge of the printed sheet to be positioned on the folding table.
  • the folding blade is designed to be stationary and has a compressed air device connected to a first compressed air source with at least one outlet opening directed towards the folding roller gap for initiating the folding of the printed sheets.
  • the folding table forms a collecting device for at least two consecutive printed sheets.
  • at least one sensor which is operatively connected to the machine control, is arranged for detecting the printed sheets transported by the conveyor.
  • At least two successive printed sheets are collected on the collecting device of the folding table to form a common stack and the stack is closed together folded a printed product.
  • a leading printed sheet to be placed on the folding table is braked in the area of its rear edge on its upper side by contact with the mechanical braking element.
  • the folding of the stack is triggered by the action of compressed air supplied from the first compressed air source from the at least one outlet opening of the fixed folding blade onto the stack.
  • a printed sheet transported by the conveyor is detected with the at least one sensor that is operatively connected to the machine control and the machine control uses information received from the at least one sensor to calculate corresponding control signals for pressing down the trailing edge of the leading printed sheet, for braking it and for actuating the folding blade, and finally releases it pressing down, braking and folding.
  • a stop for the front edges of the printed sheets to be collected on the folding table is arranged in the area of the folding table. Accordingly, in one embodiment of the method according to the invention, the front edges of the printed sheets to be collected on the folding table are conveyed against a stop arranged in the area of the folding table. In this way, an improved alignment of the printed sheets of the stack and thus an improved folding quality can be achieved.
  • the stop is designed to be displaceable in and against the conveying direction of the printed sheets.
  • the stop is shifted in or against the conveying direction of the printed sheets.
  • the at least one hold-down device is connected to the first compressed air source or to a second compressed air source and has at least one outlet opening for compressed air directed towards the top of the printed sheet to be positioned on the folding table in the area of its rear edge.
  • the at least one mechanical braking element is arranged between the at least one first outlet opening of the hold-down device and the folding table.
  • the at least a hold-down device is supplied with compressed air from the first compressed air source or from a second compressed air source and the compressed air is directed through at least one outlet opening of the hold-down device onto the top of the printed sheet to be positioned on the folding table in the region of its rear edge.
  • the compressed air emerging from the at least one first outlet opening of the hold-down device is directed to the at least one mechanical braking element, deflecting it in the direction of the folding table and bringing it into contact with the printed sheet to be positioned on the folding table or fed to the stack.
  • the device has at least two separate hold-down devices which are each arranged transversely to the conveying direction of the printed sheets at a lateral distance from an upstream end of the compressed air device of the folding blade.
  • the compressed air is applied via the at least two separate hold-down devices. In this way, the printed sheets can advantageously be held down and braked evenly and without the risk of twisting.
  • the lateral distance between the at least two separate hold-down devices is adjustable.
  • the lateral distance between the at least two separate hold-down devices is correspondingly reduced or increased in a subsequent work order with a smaller or larger format of printed sheets to be processed.
  • the hold-down devices can be adjusted according to the format of the printed sheets to be collected on the folding table. The entire rear edge of the respective printed sheet can thus be pressed down in the direction of the folding table, so that no areas of this printed sheet can collide with a trailing printed sheet.
  • the Folding blade on a number of segments arranged one behind the other in the conveying direction.
  • the compressed air supplied by the first compressed air source is introduced into the segments of the folding blade, with compressed air only being applied to the segments arranged in the region of the stack by means of the machine control. Due to the formation of separate segments, these can be activated separately and pressurized with compressed air in a targeted manner in accordance with the format of the stack lying on the folding table. In addition, turbulence of compressed air in the free space between the folding blade and the stack to be folded can be prevented and thus impairment of the correct alignment of the uppermost printed sheet of the stack can be avoided.
  • the conveyor has a lower belt and an upper belt cooperating with this for transporting the printed sheets.
  • the printed sheets are transported to the folding table in a conveyor gap formed between the lower belt and the upper belt of the conveyor. As a result, the printed sheets are clamped in the conveyor gap during their transport and can thus be accelerated or decelerated without slipping.
  • both the lower belt and the upper belt extend into the area of the folding table.
  • the printed sheets with the lower belt and the upper belt of the conveyor are transported into the area of the folding table.
  • the lower belt can transport the lowermost printed sheet of the stack to be formed against the stop and position it correctly there, while the upper belt can guide or guide the printed sheets on the folding table.
  • only one drive is advantageously required for the upper belt and lower belt.
  • the lower belt and / or the upper belt converge towards one another in the area of the folding table educated.
  • the guidance of the printed sheets in the area of the folding table is additionally supported by the converging formation of the lower belt and / or the upper belt.
  • At least two sensors which are operatively connected to the machine control system, are arranged in the area of the conveyor for detecting the printed sheets transported by the conveyor, spaced transversely to the conveying direction.
  • the printed sheets in the area of the conveyor are detected by means of the at least two sensors. In this way, any inclined position of a transported printed sheet can be identified and corrected, for example, by appropriately applying compressed air to the segments of the air sword or the hold-down device.
  • the pair of folding rollers and the folding blade are arranged longitudinally or transversely to the conveying direction.
  • the stack can advantageously be folded both longitudinally and transversely to the conveying direction of the printed sheets transported by the conveyor. If the pair of folding rollers and the folding blade are arranged transversely to the conveying direction, the hold-down devices are arranged parallel thereto.
  • the folding roller gap has a gap width which is designed to be adjustable.
  • the gap width is adjusted accordingly in a subsequent work order with a different thickness of the stack to be folded.
  • the folding roller gap can advantageously be adapted to work orders with different stack thicknesses. This is done by a corresponding relative movement of the bearing points of the folding rollers.
  • the folding rollers can also only be designed to be sprung and thereby compensate for different thicknesses of the stack to be folded within certain tolerance ranges.
