Description

  The present invention relates to a method and apparatus for feeding a sheet of security critical documents to a processing station. According to the present invention, a paper sheet stack to be a document later is transported to a processing station by a transport device capable of tact control.

  Passports, passbooks, and other security-critical paper documents are made by joining individual paper sheets together with a staple. Yarn binding is performed after the paper sheets with serial numbers are aligned and stacked, but the format is not limited to one document and a format including two or three documents at the same time is usually selected. To this end, the passport thread binding line is equipped with up to three thread binding machines. These yarn stitchers operate in a single row. In this case, since the yarn binding process essentially defines the tact time of the equipment, the total throughput of the production line for manufacturing the passport also depends on the yarn binding process.

  It is an object of the present invention to provide a method and apparatus for paralleling any number of machining stations operating simultaneously so that they can continue to operate continuously if one or more processing stations fail. That is.

  This object is achieved according to the invention by a method having the features set forth in claim 1 and an apparatus having the features set forth in claim 4. Advantageous embodiments of the invention are described in the dependent claims.

  In this arrangement, the supply unit transports documents in individual tacts and passes them to the distribution device. The dispensing device takes the supplied passport and dispenses the document to the active processing station with a freely selectable intermediate tact. After the combining process, the document is again passed to the distribution unit, and the discharge unit picks up the document.

  The arrangement according to the invention makes it possible for the entire installation to be operated continuously with individual tacts when more than one processing station is included. Any number of processing stations operating in parallel can be arranged, in which case, for example, if an individual processing station fails, it can operate continuously on individual tacts without interrupting the entire installation. That is, regardless of the arrangement configuration, one or a plurality of machines can be stopped without having to interrupt the work process of the entire facility.

  Hereinafter, embodiments of the present invention will be described in detail. The present embodiment relates to a passport thread binding.

  At the position shown in FIG. 1, the passport sheets to be joined are placed on the supply unit 3 in the form of a paper stack 5. The supply unit 3 moves the document paper laminate 5 to be processed by individual tact and passes it to the distribution device 2.

  As shown in FIG. 2, the paper sheet stack 5 is distributed on the distribution device 2 in accordance with the number and spacing of the working processing stations 1.1 to 1.4. This distribution is performed by a controlled number of empty tacts which are performed before the supply device 3 passes to the distribution device 2.

  FIG. 3 shows the start of the processing phase when the document paper stack 5.1-5.4 has reached the target position. This is a state in which the document paper laminates 5.1 to 5.4 face the inlets 1E of the corresponding processing stations 1.1 to 1.4. In this position, the paper sheet stacks 5.1 to 5.4 are fed by the dispensing device 2 to the inlets 1.1E to 1.4E, so that the working processing stations 1.1 to 1.4 (books) are activated. In the embodiment, it is handed over to a passport thread binding machine). In FIG. 3, all four passport yarn binding machines are operating.

  FIG. 4 shows the state in which the document paper stacks 5.1 to 5.4 are in the four processing stations 1.1 to 1.4 in operation. During the processing of these laminates, further rows of document paper laminates 5.1 to 5.4 are transferred from the supply device 3 to the distribution device 2. This transfer is performed in the same manner as described above.

  At the position reached in the stage shown in FIG. 5, the document paper laminates 5.1 to 5.4 can be newly delivered to the distribution device 2.

  FIG. 6 shows that a completed document (passport bound in this embodiment) is taken out from the outlets 1.1A to 1.4A of the processing stations 1.1 to 1.4 in the same tact process and is placed on the distribution device 2. The mounted state is shown. Document paper laminates constituting these documents are supplied to the processing stations 1.1 to 1.4 in the preceding work process.

  FIG. 7 shows the next tact process. Here, the processed paper sheet laminates 5.1 to 5.4 are transferred from the distribution device 2 to the discharge device 4. In the example shown, both document paper laminates 5.1 and 5.2 have already been delivered. At this time, since the discharge device 4 performs empty tact between the respective work tacts, the paper sheet stacks 5 are closely arranged here, whereas the inlet and the outlet of the processing station 1 on the distribution unit 2. Are juxtaposed, so they are twice as long. At the same time, a new paper sheet laminate 5.5 or less that has not yet been processed by the supply device 3 is supplied to the distribution device 2.

  In the procedure shown in FIGS. 8 to 10, only the processing stations 1.2 to 1.4 are operating and the processing station 1.1 is not operating. In this case, the distribution device 2 advances the tact stroke twice, and the supply device 3 performs the empty tact during that time.

  In the position shown in FIG. 8, the distribution device 2 is loaded with three document paper laminates 5.5 to 5.7 and delivered to the processing stations 1.2, 1.3 and 1.4, respectively. .

  In the position shown in FIG. 9, the paper stacks 5.9, 5.10 and 5.11 are inside the processing stations 1.2, 1.3 and 1.4 and the processing is complete. 5.5 to 5.8 are placed on the dispensing device 2. Processing station 1.1 remains empty.

  At the position reached at the stage shown in FIG. 10, three processed passports corresponding to the paper stacks 5.9, 5.10 and 5.11 are again delivered to the distribution device 2.

  FIGS. 11 and 12 contain a schematic listing for the workflow of a facility having four processing stations 1.1-1.4.

  FIG. 11 schematically shows a workflow for an arrangement having processing stations 1.1-1.4 that operate all four. In this case, the processing stage for the unprocessed document paper stack 5 is shown in black, and the stage where the processing of the document is completed is subjected to horizontal hatching. The machining process is indicated by diagonal hatching.

  In the workflow shown in FIG. 12, the processing station 1.2 is not operating.
