Definitions

  • the singling-out of piled articles plays an important role in mechanizing and automatizing the handling of documents.
  • special care has to be taken that the documents are individually fed to a conveying system with a constant minimum spacing, before being fed to the processing positions or machines. If, due to a double pull-off, two documents are conveyed simultaneously, itis likely they will be recognized by the processing machine as one single document, so that one of these documents will be completely skipped in processing. Such an error, if detected, would call for a checking of all of the already processed documents, thus making it very doubtful whether the whole system is economical. For this reason arrangements have to be provided for reliably preventing such a double or multiple pull-olf.
  • One of the features of this invention is the use of opposing forces of suction of unequal force to effect a separation of piled up articles.
  • This invention relates to an arrangement adapted to reliably avoid a double or multiple pull-off in a preferably pneumatic type of system serving the separation (pullolf) of piled flat and thin articles such as documents made of thin paper, wherein the pulled-off articles are conveyed by an apertured belt which is led over the openings of a source of suction air.
  • the invention consists in that in the conveying direction, beyond the pull-oil?
  • sucking-off airducts of both groups of outlets are assembled in one common pipe and are throttled sharply Patented July 13, 1965 ice in such a way that an undcrpressure can only build itself up with the pipe system when the large-diameter outlets on the side of the conveyor belt are throttled by the articles to be conveyed.
  • FIG. 1 is a perspective view of an arrangement in accordance with my invention
  • FIG. 2 is a schematic view of the arrangement shown in FIGURE 1.
  • a pile of equisized checks or other documents are contained in a receiving device 1. With a constant pressure this pile of articles is pressed by the action of a not shown device, against the conveying plane, so that the front article will come to lie against the belt 6.
  • This conveyor belt 6, in turn, is led over a surface on which there are arranged the outlets 2 and 3 of a source of suction air. Suction is elfected at 2 and 3 via tubes 2a and 3a. Valve V controls the suction to outlets 3.
  • the outlets 3 are arranged in the central portion of the surface, and have a high suction force.
  • the outlets 2 have a smaller suction force, and are arranged at the margins of the surface.
  • the belt 6 is provided with perforations 6a, being in agreement with the outlets 3, for performing the suckingon of one of the documents and for taking it along.
  • the belt 6 covers only the central portion of the surface occupied by the outlets 3, so that the outlets 2 remain uncovered.
  • the side of the receiving device 1 lying in the conveying direction may be formed either by a limit stop, a roller, or a retaining device 5 extending so far to the conveyor belt, that there will only remain a small gap for pulling off the conveyed articles.
  • Reference numeral 4 indicates the blowing nozzles, the purpose of which will be explained hereinafter in connection with describing the mode of operation of the system. a
  • a source of compressed air To the short pipe pieces 2a and 3a there are connected the sources of suction air, and to the short pipe piece 4a which supplies 4 with air there is connected a source of compressed air.
  • This arrangement 7 likewise consists of a surface over which the perforated conveyor belt is led, which is provided with suction-air nozzles, and furthermore of another arrangement of suction-air nozzles which, together with the aforementioned surface, forms the second opposite side of a conveying channel, and likewise contains suction-air nozzles.
  • a throttle valve B In the common airduct of both nozzles there is arranged a throttle valve B which is shown in FIG. 2.
  • the singling-out device is operated by the article to be conveyed with the aid of photocells.
  • the article to be conveyed there may be provided four light barriers 1t), 11, 12 and 13, of which the sources of light are arranged on the one side, and the receivers on the other side of the conveying channel.
  • Further suctionair nozzles 8 and 9 are disposed behind the arrangement 7 on a surface, over which the conveyor belt 6 is moved. When a document has passed through 7 the valve V is closed causing suction to go through tubes 8a and 9a to outlets 8 and 9 for conveying the document further along the system.
  • the conveyor belt is of a width which does not cover- .up the suction-air nozzles 2 or 3 respectively, and therefore need only be bent slightly or not at all.
  • the suction effect of the nozzles 3 must be substantially stronger than that of the nozzles 2.
  • the nozzles 8, on one hand, and 3, '7, 9, on the other hand, are alternately applied to a source of suction air via a quick-acting valve V By reversing this valve the system may be randomly switched to cause either the transporting or the stopping.
  • the arrangement shown in the drawings operates as follows: First of all the receiving device 1 is provided with a pile of aligned documents resting on one hand, on the base plate of the supporting device and, on the other hand, against the limit stop or retaining plate 5.
  • the front piece of the piling device (stacking device) is applied with its central portion to the bolt 6 moving in the conveying direction, whereas its two marginal-strip portions are loosened by.
  • a vacuum is applied to the nozzles 3, so that the When an article is supposed to be conveyed article is sucked so strongly against the belt 6 that it, in
  • the light barrier 12 is darkened.
  • the light barrier 12 is arranged at a point where the conveying article is taken over by a further group of suction-air nozzles 9.
  • the article itself shuts off the nozzles of the device 7 for interrupting the supply int his way.
  • the device 7 is switched-on to become effective again. In this way, between the individual articles to be conveyed, there is established a spacing corresponding to the spac- In addition ner.
  • the vacuum is switchedoif from the conveying nozzles 3, 7 and 9 by the main valve V and is applied to the retaining nozzles 3. In this way it is possible to perform a random stopping vand re-starting of the conveying operation.
