Definitions

  • the invention relates to an apparatus and method for producing documents composed of single sheets with the aid of an electrographic printing device printing on tape-like recording media.
  • Documents such as brochures, insurance policies, etc., which are created with the aid of electrographic, magnetographic or other non-impact printing devices, are preferably composed of single sheets of differently colored or differently pre-printed papers or of different grammages (e.g. paper weights).
  • Single sheet printers with different (e.g. 4) input bins are used for these applications.
  • the documents can therefore be printed in the correct sequence by appropriately selecting the input compartments.
  • Single sheet printers require increased technical effort for paper handling and printing. The transport of single sheets is also prone to failure. Only paper weights and formats in a narrow range can still be used.
  • the aim of the invention is to provide a printing device and a method of the type mentioned at the outset, with which documents can be produced from single sheets in a simple and inexpensive manner with high print quality and at high printing speed.
  • This object of the invention is achieved according to the features of claims 1 and 16.
  • Advantageous developments of the invention are characterized in the subclaims.
  • the invention combines the technical advantages of an electrographic printing device working with continuous paper, for example with regard to processing speed, print quality and economy, with the advantages of a single sheet machine.
  • the document printing device uses an electrographic individual printing device which is suitable for printing on single and double sides (simplex duplex). Due to the friction drive for the record carrier, the printing device can process roll and folded paper (leporelio paper) with and without edge perforation and with separation perforation.
  • the change of paper type is limited to a few processes, e.g. B. depending on the number of paper types. For example, in the case of a short run of a brochure in print types assigned to paper types (paper configuration), all sheets of the same paper type are printed. The cover sheets to be inserted into the brochure are first stored electronically and, after the "normal" or actual information sheets have been printed, are printed by changing the paper type once.
  • the merging of the normal sheets with the cover sheets for the brochure takes place in the printer output station, which can then also be bound or stapled as required.
  • the process flow is monitored by adding up the individual sheets and processing them in the buffer, thus guaranteeing their safe execution.
  • externally generated single sheets for example advertising brochures, can also be fed into this collating function via an external input.
  • the paper feeder can have externally arranged paper supply rolls of different sizes and paper quality. The change can be made manually or automatically via the printer control.

  • the document printing device shown in FIG. 1 combines the performance of a continuous printing device with the performance of a single sheet printing device. It essentially consists of a paper feed device PZ with two input areas E1 and E2. In the illustrated embodiment, roll paper is used in both input areas, but roll paper and pre-folded continuous paper can also be used in accordance with the embodiment of FIG. 2.
  • the input part E1 contains a large roll of paper, typically made of white paper, that is to say a recording medium from which the majority of the printed pages are made.
  • the input media E2 contains the recording media rolled up on two rolls, eg for cover sheets, ie from a type of paper that is used less.
  • rollers can also be arranged in the input compartment E2 if, for example, a recording medium is used which has a recording medium width corresponding to the examples in FIGS. 3, 4 and 5.
  • a total of four rolls can be arranged in the input compartment E2, two at the top and two at the bottom.
  • Downstream of the paper feed device PZ is an electrographic printing unit DRA, which can be designed in accordance with the exemplary embodiments of FIGS. 3 to 9, in which the continuous paper A can be printed on one side or on both sides within the unit.
  • a paper postprocessing device is coupled on the output side to the printing unit DA, which separates the printed continuous paper and assembles a document from the individual sheets.
  • the paper post-processing device contains a printed page separating device V in the form of a cutting device with associated waste disposal in the form of, for example, a container which receives the cut-off parts of the recording medium A.
  • the paper machine processing device contains an intermediate memory ZS for the job-related recording of the individual printed pages, which are stored in the form of containers designed partial memories T1 to TN.
  • the buffer store ZS contains a single sheet stacking device ES, which is operated when only one type of paper is being printed on a large scale.
  • the buffer store ZS is coupled to a job finishing device JF for document-associated assembly of printed pages removed from the buffer store.
  • the job finishing device can also contain a binding or stapling device for stapling or binding the document assembled via the job finishing device.
  • the document bound in this way is output via an output device (exit).
  • the document printing device is controlled by a job organization control unit JS, which can be microprocessor-controlled. It includes input means, for example in the form of a panel P for inputting the document structure. This entry can be made manually, but it can also be controlled via a data connection to a PC or a desk-top publishing facility.
  • the job organization control unit JS furthermore contains, for example, a microprocessor-controlled selection control unit AS, in order to print on the tape-shaped recording medium A in the printing unit DRA as a function of the document structure entered via the input unit P, to separate it and to store it in the buffer ZS job-assigned and to store the individual jobs in the job finishing device JF according to the desired document structure to merge into one document.
  • the job organization control unit JS can be coupled via interfaces to an EDP system and operated online (SCH1) or it is connected to an internal, eg desk-top publishing unit and is operated offline (SCH2). Furthermore, the job organization control unit JS is assigned a monitoring arrangement in the form of a job sequence control.
  • the counters C1 and C2 With the counters C1 and C2, the printed pages processed in the printing unit DRA are counted and compared with the individual sheets stored in the intermediate storage ZS. Depending on this comparison process, an evaluation signal is triggered by the comparison device VG. If the number is different, an error signal is generated (error). If the number of printed pages is identical, no printed page has been lost and an OK signal is generated.
  • the buffer store is also equipped with an external loading device EB via the individual sub-stores T1 to TN, e.g. externally pre-printed individual sheets in the form of advertising brochures or the like can be supplied.
  • an external loading device EB via the individual sub-stores T1 to TN, e.g. externally pre-printed individual sheets in the form of advertising brochures or the like can be supplied.
  • the entire printing facility works as follows:
  • the document structure is entered via the panels P of the organization control unit.
  • the entry can also be made from a host or from disk storage or online via the SH1 interface from a coupled computer system come.
  • the job organization control unit JS sorts the print information in a storage unit, the frequently occurring print pages being assigned to one type of paper to a storage area and the less frequent to another type of paper (eg cover sheets) to another storage area. Then everything is printed in one job by one paper type and then by the other paper type in another job.
  • continuous paper is first drawn off from the large paper roll of the input device E1 and this is printed with the frequently occurring single-sheet print data, and then this job with the printed pages is stored, for example, in the partial container T1 of the intermediate store ZS.
  • the cover sheet is then printed in a further job by pulling the paper type assigned to the cover sheet from the input tray E2, this job then being stored in the sub-tray T2.
  • the portion of the job that corresponds to one type of paper is practically always done and then transferred to the portion of the job of the other type of paper.
  • the format cut and the separation before being stored in the intermediate storage ZS takes place in the format cut device V.
  • the job finishing device JF controlled by the job organization control unit JS the document is compiled, namely by collating the jobs in the desired order by removing them from the sub-compartments T1 to TN of the buffer store ZS.
  • continuous paper of the desired type is fed automatically or by hand, depending on the requirement.
  • the continuous paper is printed, separated and a document is compiled from the separated continuous paper of various types of paper.
  • the single sheet stacker ES is used e.g. when printing brochures with a large number of printed pages from the same paper, stacking these printed pages from the same paper and then adding a cover sheet from a different paper type to the stack, for example from 50 pages of the same paper, which was then printed in a different job.
  • the printing unit DRA can process continuous paper with and without edge perforations. For this purpose, it contains a friction drive, which is described in more detail in connection with FIG. 2.
  • the job organization control unit JS essentially has a memory organization function. Depending on an index, it saves which Paper is used or what information must be printed on which paper. Depending on the job and the weight of the job, this information is saved so that it can be called up again. This information must be programmed by the operator or user via online or offline in the manner described. If, for example, an insurance policy is composed, for example, of a job of three, ie an invoice, a personal cover letter and an insurance policy, with all three individual sheets consisting of a different paper, the present document printing device, for example, first of all uses the insurance policy on one separate paper type is printed in very large numbers and stored in the partial memory T1 of the intermediate store ZS.
  • the job organization control unit JS stores the printed job but does not yet acknowledge it.
  • the invoice is printed on another paper, for example drawn from the smaller rolls, in a correspondingly large number and in the storage T2 of the intermediate storage ZS, and this job is stored and also not yet acknowledged.
  • the personal letter is then printed out, for example, this job then being stored in the partial memory T3 of the intermediate memory ZS.
  • the personalized letters are then merged as individual documents via the job finishing device JF and, for example, inserted and sent in a corresponding inserting device. If advertising brochures are now to be added to these personalized letters, these advertising brochures can be supplied via the external loading device EB.

  • the tape-shaped record carrier A is fed via a paper feed device PZ in the following manner.
  • a paper input device 1 the continuous paper, which is made up as pre-folded leporello paper, but has no lateral transport holes, is first deflected or braked via two fixed axes 2 (paper divider) without substantial web tension.
  • the fixed axles 2 work both as a light brake and as a paper divider, e.g. to separated web layers from one another, in a web pre-centering 3 the paper web is deflected (approx.
  • the tension in paper web A is increased by a web brake. It is important that the paper web A is braked only in the transport direction and not at an angle or asymmetrically. This can be done, for example, by means of a vacuum brake 6 with an associated vacuum pump 7. Due to the tension, the paper web A aligns itself in the drive 8 and looks for a central position.
  • the drive of the paper guide 8 is designed as a friction drive with as little slip as possible or a constant coefficient of friction for the service life, for this purpose it contains two friction rollers 13, between which the record carrier is passed. The higher the tension, the less the lateral pendulum movements of web A and vice versa. This relationship also applies to the flatness of paper web A.
  • Deflection rollers 9 arranged behind the vacuum brake 6 form a stabilization zone in which the paper path of the paper web A is stabilized. Drift-side drift influences on the paper web or on the contact of the paper web with the web delimitation 5 in the web pre-centering device 3 are thereby greatly reduced.
  • the effect of the stabilizing rollers 9 is particularly effective with the largest possible wrap (large contact surfaces) and with friction linings on the rollers.
  • a mechanical belt store in the form of a loop puller 10 is arranged in the stabilization zone, with two fixed rollers and one oscillating roller which is moved against a spring.
  • the eyestrainer keeps the paper web A under tension during start-stop backward transport. It prevents the recording medium from tearing.
  • the tension in the paper web A for this case is somewhat below the usual tension and is almost constant over the entire working range of the loop puller up to the stop. After passing through the loop puller, the paper web A is fed to the friction drive 8 of the printing unit DA.
  • the printing device is operated with roll paper which is pulled off a roll 11, it is favorable to separately drive or brake the roll 11 as shown.
  • the drive of the roller 11 or its brake is controlled so that a defined loop 12 is formed between the roller 11 and the paper 1, which serves as a mechanical paper storage.
  • the feed into the web pre-centering 3 thus takes place under similar conditions as when operating end staple paper stacks of the paper input 1.
  • the continuous paper guide can be functionally subdivided into the following steps: paper input via roll or stack with the following web pre-centering by lateral paper installation in a web pre-centering device.
