Definitions

  • the present invention relates to a device for producing printed products according to the preamble of claim 1 and a method for producing printed products according to the features of claim.
  • EP 1 816 007 A1 It is known to produce different printed products one after the other in small runs using a digital printing machine. All pages of a book block are printed in a digital printing machine, the printed pages are then stacked to form a loose book block and then bound with a binding device connected downstream. Individual sheets can be printed that have previously been pulled off a roll and already cut to size, or the printed paper is cut into individual pages after printing, or the pages are printed in printed sheets and the folded printed sheets are stacked to form loose book blocks, depending on how folded or cut is done.
  • the loose book blocks are further processed in a further processing device in the form of a binding device. For this purpose, two or more envelopes are provided so that production can be carried out without interruption.
  • the printed products and the envelopes are each brought together in separate ways to connect them in the back area in the further processing device.
  • a method for producing printed products by means of a system which has a control device, at least one printing machine for producing book blocks, at least one transport device for transporting the book blocks and at least one further processing device, in which each book block is provided with a cover.
  • a digital printing machine is used as the printing machine, as this technology can be used to print a single printed product completely in one sequence.
  • the individual production steps of book production are carried out immediately one after the other in an inline process in which the individual machines the control device are networked with each other. It is assumed that, in particular, softcover covers or hardcovers for the printed products generally have to be pre-produced and stored in a storage facility.
  • the order to a printing press to produce a book block is only triggered by the control device when an envelope is fed into the memory.
  • the individual machines for printing and further processing are networked via the control device in order to be able to produce, if possible, quickly and efficiently at high cycle rates in an edition size of 1, without having to accept inferior quality .
  • This requires a consistent production workflow with coordinated interfaces through real-time status information.
  • the books to be produced can vary from book to book in terms of their content, cover, format and thickness.
  • the output of book blocks depends on the format and thickness. The larger the format and/or the thickness of a book, the lower the output.
  • the book covers are usually printed as sheets.
  • the invention is based on the object of creating a device and a method of the types mentioned, which make it possible to produce printed products in very small runs down to a single printed product more economically. It should be possible to produce the covers efficiently, if possible automatically and without manual intervention, and to connect them to a book block.
  • the task is solved for a generic device with the characterizing features of claim 1.
  • the task is solved for a method with the features of the claim.
  • the temporary connection is usually removed again in one of the subsequent processing machines as soon as the book blocks have been held by a clamping or gripping device or have been permanently connected to one another.
  • the digital printing machine with its associated peripherals for printing on an envelope can be provided with appropriate feeding and connecting technology for the laminate material and/or a powerful varnishing technology for applying a layer of varnish to the respective envelopes.
  • the book blocks in an adhesive binder are not provided with a cover, but with a folding strip that covers the spine glue.
  • the book blocks for hardcover books can be fed automatically or manually to a hanging machine after a cutting machine in which the book blocks are cut to the desired format on up to three edges.
  • the corresponding book blocks are provided with a preferably digitally printed hardcover cover. Both the hanging machine and a machine for producing hardcover envelopes can be part of the generic device or connected to it.
  • the book blocks can be transported in a suitable manner in a first transport device.
  • they can be transported lying down, for example on conveyor belts or tables, on trays - a shell-shaped transport element for one book block each - or in a conveyor channel, or hanging, for example in a gripper or in a bag.
  • Cutting devices, folding devices or collecting devices can be integrated into the first transport device and form part of the first transport device.
  • the digitally printed and optionally laminated and/or varnished envelopes are transported further to the digital printing machine and fed to an adhesive binder.
  • the book blocks and envelopes produced by the digital printing machines can each be fed to a specific perfect binder.
  • the two material streams with the book blocks and the covers can therefore be directed via the switches to one of several perfect binders. This can be the perfect binder that appears to be most suitable for connecting these components into a book at the time of production.
  • the switches make it possible to control the flow of the book blocks and envelopes through the device in such a way that each book block and each envelope is fed exactly to the perfect binder in which these components are to be assembled.
  • the switches make it possible to implement optimization criteria according to which the allocation of the perfect binders with further processing jobs is planned, through an appropriate material flow.
  • the special digital printing machines with their associated process-optimized machine peripherals for the production of book blocks and covers with the optimized feed of these components via the switches to the perfect binder, which is rated as particularly suitable for the production of the respective printed product, it is possible to exploit the optimization potential from both to combine specialized printing as well as the allocation of the perfect binders with further processing jobs according to optimization criteria.
  • the feed times of book blocks and envelopes to the perfect binders can be varied to a greater extent than by simply changing the conveying speeds of the conveyor systems used on the conveyor routes.
  • the product storage in the transport routes for both the book blocks and the covers creates the possibility of selecting the right book block from the book to eject the corresponding transport route if the production of the associated cover is delayed due to a malfunction or error, or to eject the appropriate envelope from the corresponding transport route if an error occurs in the production of the associated book block. It is also possible to set the clock rate of the digital printing machine used to produce the book blocks higher than the processing capacity of the adhesive binder used in order to build up a material buffer that can be processed again later in the event of malfunctions or maintenance work on the digital printing machine.
  • the book blocks and envelopes introduced into the respective product storage can be reintroduced from the product storage into the material flow of the transport device as soon as the pairing of a book block with the associated cover is available and a free work cycle is available in the perfect binder in which the corresponding book block with the corresponding envelope should be further processed.
  • a storage wheel for example, can be used to store the envelopes.
  • the storage capacity of the product storage should be sensibly chosen so that: Storage volume covers the usual operating requirements.
  • the product stores can be designed in such a way that they make it possible to eject stored products only in the order in which they are ejected, in the opposite order in which they are ejected, or in an individual order determined by the control device.
  • control device By integrating the control of the function of the switches and the product storage into a control device, it is possible to include the operation of these components in the control of the digital printing machines, the transport devices and the perfect binders.
  • the function of the individual machines is networked with one another via the control device and corresponding interfaces in the control device and the machines controlled with it, which allows optimized operation of the entire system.
  • the control device can be used to plan and dynamically execute the workflow for each individual print product.
  • the production workflow for the book blocks and covers can be controlled so that it can be dynamically adjusted and changed during production, eliminating manual Interventions are minimized and there is an improved utilization of the adhesive binders with a high product quality of all printed products produced with the device.
  • the control device In order to be able to control the device with the control device, it is necessary that the control device continuously receives status information about the status of the individual machines and the products passing through the device.
  • the control device therefore knows at all times where every book block, every cover, every glued or cut book is located.
  • the status information about the machines controlled by the control device can be exchanged via the interfaces in the control device and the machines.
  • the machines are equipped with sensors that collect and provide the data required for status information.
  • the status information required by the control device for planning and production control of the book blocks and covers can be provided via additional sensors such as barcode or QR code readers, cameras, light barriers and the like, which transmit their sensor data directly or indirectly to the control device.
  • the respective status information can be transmitted to the control device in real time.
  • the covers can be used to produce a softcover book.
  • the device and the method can also be used to provide book blocks for hardcover books in an adhesive binder with a fold instead of with an envelope. It is then not necessary to print a separate cover for further processing of book blocks for hardcover books.
  • the machines of the device can then be controlled accordingly by the control device.
  • the control device has a computer program which, for each order for the production of a printed product, creates an evaluation in a program routine as to which of the adhesive binders present in the device is most suitable for the book block to be produced for this printed product and for this printed product Envelope to be made together connect.

  • All or at least some of the above aspects can be taken into account in the computer program by appropriate programming when deciding which printed product is further processed on which adhesive binder.
  • the computer program in the control device can therefore be used to determine which of the adhesive binders present in the device appears most suitable for joining the book block and the cover of a printed product.
  • the computer program After the program-supported evaluation, the computer program also generates the control signals with which the first and second transport devices, the switches present in the transport devices and the product storage are controlled so that the corresponding book blocks and envelopes are also fed to the selected perfect binder at the same time.
  • book blocks and covers are buffered according to defined group criteria.
  • the removal of book blocks and envelopes is not limited to a single printed product; it is also possible to form groups of products in the product memory.
  • the products removed in groups can later be further processed individually or as a group of products.
  • thinner book blocks can be temporarily stored in the product storage in order to then feed them to the respective perfect binders when the digital printing machine for printing the book blocks is busy printing one or more thicker book blocks, the production of which naturally takes a little longer than an average thick book block.
  • An empty work cycle in the perfect binder which is caused by the printing of a thicker book block and the resulting longer conveying interval until the thicker book block is fed into the perfect binder, can then occur with the feeding and adhesive binding of a thinner book block from the product storage.
  • the group formation in the product stores can also be logistically driven, in that the components for those printed products that are to be sent later or in a different shipping package are first introduced into the product store in order to process them later.
  • At least one cutting machine is arranged downstream of the perfect binders in the material flow, with the device for transporting the book blocks further processed in the perfect binders or the printed products to the at least one cutting machine being designed as a third transport device serving as a cooling section.
  • the cutting machine can be used to cut the book blocks or printed products that are perfect bound in the perfect binders and have covers or folds to the desired size.
  • the third transport route is used to allow the glue applied to a book block in the perfect binder to cool and dry.
  • the perfect binders can also be followed by several cutting machines on which the glued book blocks or printed products are trimmed. The throughput of the cutting machines should match the throughput of the existing perfect binders.

  • the at least one cutting machine, the fourth transport device, the first discharge switch and/or the second discharge switch are controlled by the control device.
  • the material flow in the device can be further optimized beyond controlling the material flow for merging the book blocks with the covers.
  • the control device can feed the at least one cutting machine, control the sorting and distribution of the glued book blocks and/or remove faulty components. The functions of these machines can be integrated into the overall optimization of the operation of the device.
  • the control device uses the programming of the computer software to assign print jobs to the digital printing machine for printing the book blocks as a master production line, and the assignment of print jobs to the digital printing machine for printing the envelopes is subordinate to the print jobs for the master production line.
  • the digital printing machines for envelopes are often sheet-fed printing machines, which are often only operated in stop-and-go mode due to the lower resource requirements for envelope printing.
  • the prioritized assignment of the digital printing machine for printing the book blocks enables the operation of this printing machine to be optimized and thus an increase in the performance of the device as a whole, in that the sequence of these print jobs can be sorted taking into account optimization criteria without taking the print jobs for the digital printing machine for the envelopes into account .
  • the computer software of the control device is designed to control the sequence of print jobs for the digital printing machines, the supply of book blocks and envelopes to perfect binders, the insertion and removal of book blocks and envelopes into and out of the product stores, the supply of perfect-bound or with a book block provided with a fold to a cutting machine, to change the material flow in the fourth transport device and / or the discharge of products in the discharge switches, taking into account current operating parameters of the device.
  • the operation of the device can be adapted to changing operating conditions. For example, if a perfect binder fails due to a malfunction or change in equipment, the transport of the book blocks and covers planned for further processing on this perfect binder can be redirected to another perfect binder that is still producing or to the product storage.
  • the computer software of the control device is designed to move book blocks and envelopes in the associated pair of a printed product into or out of the product memory present in the first and second transport devices and/or into those present in the first and second transport devices to control exit routes.
  • the advantage of the paired control of the material flow of the book block belonging to a printed product and the cover is that it prevents a perfect binder from being fed only a book block without the associated cover or an envelope without the associated book block.
  • a product storage in the second transport device such as a storage wheel, can also be used to adapt the order in which already printed envelopes are transported in the second transport device to the order of book blocks that are transported in the first transport device.
  • the first transport device is set up to transport at least two book blocks in a stack, at least in sections.
  • the conveying capacity of the first transport device is increased or the speed at which the book blocks are transported is reduced.

  • the computer software of the control device can be designed so that it triggers the print job for printing an envelope in its program flow without waiting for a separate sensor signal.
  • the pressure can then be triggered by the software program, for example in a purely time-controlled manner.
  • a barcode or a QR code can be printed on one side of the book block, which is read by a corresponding scanner as a sensor unit.
  • the signal read by the scanner can be transmitted as a sensor signal to the control device and/or the digital printing machine for printing the envelope, thereby triggering the printing of the envelope.
  • the device has at least two digital printing machines for printing envelopes.
  • the multiple digital printing machines for printing envelopes make it possible to specialize the digital printing machines and their associated peripherals. For example, a first digital printing machine can only be intended to print envelopes that are then matt laminated or matt varnished and conveyed away by the second transport device, while a second digital printing machine is intended to only print envelopes that are then glossy laminated or glossy varnished and then transported away using the second transport device.
  • the plurality of digital printing machines for printing envelopes may be connected to and controlled by the control device.
  • At least one digital printing machine for printing an envelope has a sensor unit connected to the control device for checking at least one quality feature of a printed envelope downstream in the conveying direction of the envelopes.
  • the control device generates at least one control signal to a transport device, at least one switch, a product storage or a rejection switch when an error in an envelope is detected by the sensor unit. Errors that can be detected by a sensor unit include, for example, skewed printing, faulty lamination or uneven painting.
  • the faulty envelope can be removed from the second transport device by the control device using appropriate control commands via an ejection switch.
  • the printing of a new envelope can be triggered.
  • control device can use appropriate control commands to remove the book block belonging to the envelope recognized as defective from the first transport device, transfer it to a product storage or park the book block in front of the perfect binder or lead it into a loop until a new and error-free envelope is available.
  • a sensor unit can be arranged downstream of the digital printing machine for printing a book block, which checks the quality characteristics of the compiled book block and transmits errors to the control device. The control device then generates corresponding control commands and transmits them to a transport device, at least one switch, a product storage or a discharge switch.
  • control commands do not have to be limited to machines that are on the planned conveying path of the defective product, but can in particular also be transmitted to machines that are on the conveying path of the associated book block or envelope in order to avoid that a perfect binder only has one Book block or just an envelope is conveyed and the complementary product for binding the printed product is missing.
  • the device has at least three adhesive binders to which the book blocks are distributed via the first transport device.
  • a single first transport device can be sufficient to distribute them to at least three perfect binders to distribute.
  • the first transport device can then have the components described above in order to optimize the material flow over it and the control device.
