Method of preparing an item to be mailed and system for carrying out that method

Abstract: The invention relates to a method of preparing an item to be mailed using a printer in which a main document is printed and a line of mail preparation stations comprising an inserter station, responsive to an output, comprising instructions for controlling the printer and the mail preparation stations, said instructions for controlling the mail preparation stations being detected and fed to those mail preparation stations. According to the invention the main document is fed directly from the printer to the mail preparation stations and the supply of the instructions for controlling the mail preparation stations is carried out in accordance with the printing of the main document. Further, an apparatus according to the invention is set forth, to be used for carrying out the method according to the invention.

Description: Method of preparing an item to be mailed and system for carrying out that method. The invention relates to a method according to the introductory part of claim 1. Such a method is known from GB-A-2,202,660. In the method known from that publication the detected instructions for printing markings for controlling the mail preparation stations are removed and replaced by instructions for printing identification markings. The control signals are stored in association with an identification code which corresponds with the printed identification code. The instructions for controlling the mail preparation stations may comprise instructions for controlling a burster, an insert feed station, an address printer and a postage meter. When, for instance in the mail room, the main documents are fed to the mail preparation line, they are passed along a scanner which periodically reads the identification code provided on them. Depending on which identification code is read, periodically the associated, stored control signals are fed to the mail preparation stations. Although markings which form an identification code may be smaller than markings which themselves comprise the instructions for controlling the mail preparation stations, the presence of such markings nevertheless constitutes a disturbing element on the main document, because they are not relevant for the user of the main document and because the space where the markings are provided cannot be used for any other printing. A further drawback of using markings is that the mail preparation line requires a scanner for reading the markings. A method in which the user will find the presence of markings less disturbing is set forth in EP-A-0,265,192, where the identification markings are so designed, dimensioned and positioned that they will not be noticed by the user. It is an object of the invention to provide a method of preparing items to be mailed with which the above described drawbacks can be avoided. A further object of the invention is to change as little as possible the methods known and used heretofore, such as described above, so as to allow those methods and the apparatus used in them to be adapted through a minimum of steps, in such a way that the problems described hereinabove will be avoided This is accomplished by carrying out the method of the above described type in accordance with the characterizing part of claim 1. This makes it possible for the mail preparation stations to be controlled independently of the printing and subsequent reading of markings, the drawbacks discussed hereinabove thus being avoided. The mail preparation stations are controlled more directly in that the output is directly converted into control signals for the corresponding mail preparation stations, without the detour via printing and reading. Surprisingly, therefore, it has turned out to be possible to avoid the drawbacks discussed by choosing a shorter route in the existing methods, which also brings with it the advantage that those known methods can be adapted without any major changes. Furthermore, the use of this inventive, shorter route eliminates a source of possible disturbances, since it rules out disturbances owing to the incorrect or incomplete printing and/or reading of any printed markings. An additional advantage of the invention is that a considerably smaller number of sets of instructions each belonging to a main document need to be stored at the same time. Preferably, periodically a next main document is printed after the preceding main document has been fed to the intended mail preparation station, so that at most the instructions belonging to one main document need to be stored. The detected instructions, which are converted into control signals, may be removed from the output fed to the printer. The removed instructions are then replaced with printing instructions, for instance to leave at least one line or a part thereof blank, the initial addition of the instructions to the output may advantageously be accomplished in the space of the first line of a document, since this line is usually blank. Instead of removing the instructions for printing processing instructions, it is also possible to process the detected instructions in such a way that they are not recognized by the printer as printing instructions. In virtue of the fact that in principle it is possible to maintain the original output method where the instructions for controlling at least one mail preparation station are fed in the form of printing instructions for printing the markings comprising coded information for controlling a mail preparation station, it is advantageously possible, and in accordance with a further embodiment of the method according to the invention, for the detected printing instructions for printing the markings to be partly removed or processed into instructions which effect no printing and to be partly passed on to the printer in unmodified form for printing one or more markings. This procedure is particularly advantageous when the main documents are to be removed from the mail preparation line temporarily, for instance for a special check, or to be signed or the like. As noted, preferably the basic system of the existing mail preparation lines is changed as little as possible. In this connection it is preferable, and in accordance with a further embodiment of the invention, for the output from the data processor to be fed to an interface, which from the output received generates separate information streams to the printer and the various mail preparation stations. Further control is possible when, in accordance with a further elaboration of the invention, it is arranged for the interface to be further fed with signals coming from the printer and the mail preparation stations, which permits the control of the printer and the stations mentioned and the output from the data processor to be regulated depending on the course of the processes in one or more stations. The process can be further automated and controlled when signals are fed to the interface which come from further apparatus, such as means for monitoring technical failure, completeness or packet thickness, which influence the progress of the process in the mail preparation line. A further advantage of the use of an interface is that at the interface additional information can be added, which can be coupled to the output. Thus at the interface further preparation instructions can be added to the output coming from the data processor. The invention can also be embodied in a system according to claim 8. Preferably the interface is provided with further input means for instructions. It will be clear that the interface may be accommodated in the housing of the printer or in the same housing as the data processor and that the printer may be accommodated in the mail preparation line. The mail preparation method and system according to the invention will now be further explained and illustrated with reference to the drawings, schematically showing some embodiments, in which: Fig. 1 shows a first embodiment of a mail preparation system according to the invention; and Fig. 2 shows a second embodiment. In Fig. 1 the block designated by reference numeral 1 represents a data processor in which the information for preparing and assembling a plurality of documents is stored. The arrows between the blocks each represent a line for passing on information. Linked to the data processor 1 is an interface 2 which is arranged upstream of a mail preparation line 3 comprising, in the present embodiment of the invention, a printer 4, a burster 5, a collecting station 6, an insert feed station 7, a folding station 8, an inserter station 9 and a postage meter 10. It is stressed that the type, the number, and the sequence of the apparatuses constituting the mail preparation line are exclusively referred to by way of example and can in many ways be varied and adapted to particular uses. Arrow 11 indicates the direction in which sheets, envelopes, and enclosures are processed into items to be mailed proceeds. It is observed that the use of a burster 5 in principle implies printing on continuous forms. Naturally it is also possible to use a printer that works with loose sheets, such as most laser printers. In that case the burster 5 may be omitted. The information about the documents to be produced is generated by the data processor 1 in the form of printing instructions for the printer 4. A part of the printing instructions is directed to the printing of markings which can be read before or in the collecting station 6 and subsequently could be converted into control instructions for the various mail preparation stations. The output coming from the data processor 1 is fed to the interface 2 which detects the instructions for controlling the mail preparation stations from this output and converts them into control signals which are passed on to the stations in question. The detected and converted instructions are removed from the output or replaced with instructions for printing a blank space or line or a text, such as a standard headline. As noted above, the instructions for controlling the mail preparation stations which are converted into control signals, are passed on to the stations 5 - 10. These control signals are to lead to the desired treatment the moment the documents or a set of documents belonging together have reached the station which the instructions relate to. When a number of documents or sets of documents which are to be kept separate are simultaneously present in the mail preparation line, the moment at which the treatment in question is to be carried out can be determined extremely reliably by means of the interface 2 and feedback signals returned to it from the stations or using synchronisation signals generated by the interface 2 itself. In the latter case the feedback of signals from the stations 5-10 to the interface 2 may optionally be omitted. It is recommendable, however, at least to provide for technical failure to be monitored and reported to the interface 2 to permit the mail preparation line 3 to be stopped automatically in the case of technical failure. In some cases it is desired that the printed documents are first removed from the mail preparation line 3 for them to be further processed manually, for instance to be signed. It may also happen that the printed sheets are to be processed in a mail preparation line elsewhere. In such cases it may be preferable to print the instructions for controlling certain mail preparation stations anyway, i.e., to provide certain optically visible and readable markings on the documents. To this end the instructions in question can be added to the output. This can be done by adding those instructions to the output in the data processor 1. This may also be done at the interface 2, to which end it may be provided with a separate input. It is preferable to provide such an input not just for this purpose, but also for optionally coupling additional processing instructions to the output, for instance standard instructions relating to the preparation of a batch of items to be mailed. Fig. 2 shows one of the possible variants of the apparatus according to Fig. 1, like parts being designated by like reference numerals in both Figures. Accordingly, a data processor 1 is provided in which information for preparing a plurality of documents is stored, which information partly consists of printing instructions and partly of instructions for the assembly of sets of documents. The instructions referred to are passed on to an interface 2, which in turn is capable of separating from the output at least a part of the instructions for assembling sets of documents or for controlling one or a plurality of the mail preparation stations 5 - 10. As in the case of the embodiment according to Fig. 1, the printing instructions are passed on from the interface 2 to the printing apparatus 4. The separated instructions for controlling the mail preparation stations are passed on by the interface 2 to a control unit 12 which feeds the instructions to the mail preparation stations concerned. Such an embodiment of the apparatus may for instance be advantageous when a known apparatus is to be adapted in which the control unit 12 originally received its instructions from a reading apparatus which detected the markings provided on the documents by the printer. To obtain a set of documents, as shown in Figs. 1 and 2, a collecting station 6 may be arranged in the mail preparation line 3 directly after the printer 4 or, in the case of continuous paper, after the burster 5. Thus the assembly of a set of documents can be accomplished without printing the corresponding markings on the separate documents by converting the corresponding instructions directly into control signals in accordance with the present invention. When the set comprises a letter to be signed, for instance, it may to that end be removed from the mail preparation line by a corresponding control action in the collecting station or any other successive mail preparation station. When afterwards the set is to re-enter the mail preparation line or another mail preparation line, it is preferable to have the printer referred to above print further preparation instructions on the documents in the form of markings. In that case, therefore, a part of the instructions is directly converted into control signals and another part into markings. When in such a case an apparatus according to Fig. 2 is used, a control unit 12 may be provided which can be fed with information by the interface 2 and by a reading apparatus (not shown). Then all the desired treatments can be carried out with a minimum of markings being printed on the documents. It will be clear that many modifications and variants will readily occur to a person skilled in the art without departure from the invention. As already noted, the mail preparation line may comprise any desired number of parts of any desired type arranged in any desired sequence. Further, each of the arrows designating the flow of information between the various parts of the apparatus is provided with arrowheads, at its two ends, to indicate that feedback signals can be generated so as to obtain optimum control of the apparatus. Such feedback signals may comprise all kinds of information, such as the completion of a certain process step, the passage of a document or set of documents, the report of technical failure, etc. Further, in the drawings the interface is invariably represented as a separate unit. It will be clear that the interface can also be accommodated in the housing of the printer or in the same housing as the data processor or the control unit which in turn may be accommodated in another housing, such as that of the printer. In other words, the block units shown in the drawings need not be seen as material units. In fact, all units can in principle be accommodated in one single housing.
