Definitions

  • the present invention relates to counting apparatus for counting articles travelling along a transfer path and which is particularly adapted to count products, for example journals, delivered in imbricated manner from a rotary press, by means of a counting pulse emitter having a feeler which projects into the path of movement of the products and is operatively connected with a counter.
  • the counting pulse emitter of known counting apparatus is arranged in fixed position a certain distance above the transfer path, the feeler projecting by an adjustable amount into the path of travel of the products to be counted. With differences in the respective levels of the products, which differences often occur with articles delivered in imbricated manner from the rotary press, according to the speed thereof, or in dependence on other factors, the counting pulse emitter then fails to operate, since the feeler which is adjusted to an ideal height is deflected too much or not at all.
  • these results are obtained by counting apparatus of the above type in which a counting pulse emitter having a feeler projecting into the path of movement of the articles is operatively connected with a counting device and is restrained from movement in the transfer direction of the articles, but is mounted to freely float in a vertical plane and is adapted to be directly supported by the articles travelling along the transfer path.
  • FIGURE 1 is a view in elevation of the counting pulse emitter partly shown in section and FIGURE 2 shows a plan view of the counting pulse emitter.
  • the transfer path is formed by a conveyer belt 1 on which travel the articles 2 to 'be transferred which, in this example, are assumed to be journals delivered in imbricated manner from a rotary press.
  • a fixed bearing bracket 3 is arranged above the belt 1 and serves for the pivotal suspension of a link 4 extending in the transfer direction T.
  • the free end of link 4 is forked at 5 and carries a journal pin 6 for pivotal connection of a housing 7 of a pulse emitter 8 and for rotatably mounting a supporting wheel 9.
  • the housing 7 of the counting pulse emitter 8 is supported directly upon the conveyor belt 1 or upon the printed products travelling on the conveyer belt by means of the supporting wheel 9 as well as by supporting rollers 10 disposed at the opposite end of the housing 7.
  • Several times folded, thick printed products, for example newspapers, and also lighter printed matters can pass underneath the counting pulse emitter in this arrangement without upsetting the imbricated position of the printed products.
  • a two-armed lever 11 is mounted pivotally about an axis 12 in the housing 7 of the counting pulse emitter, one arm 11 of the lever 11 extending downwardly from the housing 7 acts as a feeler while the other arm 11", under the influence of a spring 13, abuts against the end of an adjustable stop screw 14.
  • the arrangement is such that the extremity of the feeler 11' will be positioned slightly above a line forming a tangent to the supporting wheel 9 and to the forward roller 10. It will be understood that this particular positioning of the feeler 11' mainly is a matter of adjustment which may be varied according to the particular conditions.
  • the lever arm 11" is provided with a wing 15 having a hole 16 through which passes a light beam of a light source 17 of a photoelectric pulse exciter 18 when the lever 11 is in the illustrated position abutting against the abutting screw 14.
  • the light 'beam 19 strikes a photoelectric cell 20.
  • the use of a photoelectric pulse emitter contributes somewhat to the accuracy of the result of the count, and owing to the absence of mechanical contacts also improves the reliability of the apparatus.
  • a similar advantage results from the use of the supporting wheel 9, since this wheel on the one hand depresses the forward edge of the printed products, and on the other hand assists in retaining the feeler 11 in the correct position.
  • the supporting wheel could also be omitted.
  • the counting pulse emitter could also be supported for example by means of skids or otherwise in suitable manner. Generally it can be stated that any manner of supporting the counting pulse emitter upon the products will be suitable to obtain the absolutely correct counting result which actually has been attained with the described example of construction.
  • a counting device for counting flat articles conveyed along a transfer path in partially overlapping, imbricated arrangement, said device comprising: an impulse transmitter, first means piv'otally supporting the transmitter and resting at one location on the articles, said first means restraining movement of the impulse transmitter in the direction of the transfer path, and second means coupled to the impulse transmitter and resting upon the articles at a second location disposed in spaced relation with said one location, said transmitter includ- 7 ing a feeler projecting into the path of the articles between said two locations for sensing the passage of the articles for feeding a pulse counter which is operatively associated with said transmitter to count the number of pulses which are generated as a result of the feeler sensing the passage of the articles.
  • a counting device in which the feeler is arranged above a line connecting the said two locations.
  • a counting device according to claim 2 wherein said first means includes a link having one end hingeably supported from a fixed support and an opposite end hingeably connected to the impulse transmitter and defining a pivotal axis therefor.
  • a counting device according'to claim 3 wherein said first and second means respectively comprise a wheel rotatably supported at said locations, one of said wheels being supported for rotation about the pivotal axis for the impulse transmitter.
  • a counting device in which the impulse transmitter includes a photoelectric pulse transmitter comprising a photoelectric cell and a light source facing said cell.
  • a counting device includes a pivotally supported lever and a wing on said lever having an opening through which a light beam from said source passes to the photoelectric cell, said lever being pivotally moved by the passage of an article to cause the light beam to be interrupted by the wing,
  • a counting device for counting flat articles conveyed along a transfer path in partially overlapping imbricated arrangement, said device comprising: means pivotally supported for movement about a fixed axis located above the transfer path, an impulse transmitter, housing means supporting the impulse transmitter from the first said means for pivotal movement about an axis remote from said fixed axis, and means for supporting the housing means and the impulse transmitter therewith on the article being conveyed at spaced locations, said impulse transmitter including feeler means pivotally supported from the housing means to project between the spaced locations into the path of the articles for contacting the passing articles to be pivotally moved thereby,
  • said impulse transmitter being adapted for connectionwith a pulse counter which counts the number of pulses which are generated as a result of the feeler means sensing the passage of the articles.
