Definitions

  • a device for detecting the presence of an article on which it is desired to carry out an operation by means of a further device or machine comprising a pivotally mounted vane and at least one nozzle arranged to be connected to a supply of pressurised fluid, the article being arranged to pass between the nozzle and the vane so that the absence of an article between the nozzle and the vane will result in a stream of pressurised fluid impinging on the vane to move it to a first position, whereas the pressure of an article between the nozzle and the vane will interrupt the stream of pressurised fluid to enable the vane to move to a second position in which the vane or a part movable therewith actuates means for initiating operation of said further machine or device.
  • This invention relates to an article detecting device.
  • a device may be used for example where it is required to carry out an operation of some kind on a series of articles which are advanced in succession to a station where the operation is to be carried out.
  • the operation itself may be performed automatically but obviously it is desirable to ensure that an article is actually positioned in the operating station before the machine or other means carrying out the operation is actuated.
  • Devices for detecting the presence or absence of an article are known but many of these devices are electrically actuated and suffer from disadvantages such as fire hazard or (particularly when the devices are operating in wet conditions) the possibility of malfunctioning.
  • the object of the present invention is to provide an article detecting device which is simple and inexpensive to construct and yet reliable and eflicient in operation.
  • An article detecting device in accordance with the invention comprises a pivotally mounted vane, at least one nozzle adapted to be connected to a supply of pressurised fluid whereby in use at least one stream of such fluid can be directed towards said vane, the vane and the nozzle being arranged so that articles to be detected will pass between the vane and the nozzle, the vane being pivotable between a first position to which it is deflected by the stream of pressurised fluid impinging on it in the absence of an article between the vane and the nozzle and a second position which it assumes when said stream of pressurised fluid is interrupted by the presence of an article between the vane and the nozzle, there being provided means actuable by the vane when the latter is in said second position for initiating operation of a further machine or device at a pre-determined interval after the vane has moved into its second position.
  • said means actuable by the vane includes a rotatable table which carries at spaced intervals around its periphery a plurality of actuator elements which are each mounted so as to be pivotable relative to the table about an axis which is parallel to the axis of rotation of the table.
  • the table would be rotated in use at a speed which corresponds to the speed of advance of articles (e.g.
  • a vane 10 which is mounted at or adjacent to the lower end of a rod or arm 11 which is pivotally mounted at its upper end on a support 12 so as to be pivotable about a horizontal or generally horizontal axis.
  • the vane is conveniently of part-cylindrical configuration with the axis of curvature extending in a vertical direction and facing the concave side of the vane is one end of a tube 13, the other end of said tube being aligned with at least one nozzle 14 which is adapted to be connected in use to a supply of pressurised fluid such as compressed air.
  • the tube 13 can be dispensed with and the stream of air issuing from the nozzle will, in the absence of an article between the nozzle and the vane, impinge directly on the vane.
  • one nozzle is used but two nozzles may be used so that both air jets have to be interrupted before the vane can assume its second position. This arrangement is required when an empty work holder itself interrupts the air jet from a single nozzle-the use of two nozzles requiring that both air jets must be interrupted (by an article) before the vane will move to its second position.
  • a table 17 which is rotatable about a vertical axis and which carries at spaced intervals around its periphery a plurality of actuator elements 18 (three of said elements being shown) which are each mounted so as to be pivotable relative to the table about an axis 18a which is parallel to the axis of rotation of the table.
  • the actuator elements can alternatively be carried by a belt or chain but in this instance each element conveniently extends through the table and on one side of the table there is provided a bar 19 which projects from opposite sides of a short spindle 20 which forms part of the actuator element and on which the element pivots.
  • each bar can move between a pair of short pegs 21 which act as stops to limit the angular movement of said spindle whilst the outer end of the bar 19 projects outwardly beyond the periphery of the table so as to be engageable by an arm 22.
  • Said arm is resiliently mounted or (as shown) is itself resilient so as to be biased towards an inoperative position (indicated in dotted lines by reference numeral 22a) in which it will not engage the outer end of the bar 19 of an actuator element as the table 17 rotates; 0n the other hand, when an article 15 is present between the nozzle and the vane, the latter will move to its second position.
  • the articles 15 would be delivered in succession by a conveyor 26.
  • the rotatable table 17 would also be driven (by any conventional means) at a speed corresponding to the speed of advance of said conveyor.
  • the table and the conveyor may be mechanically interconnected as shown in the drawing by a driving shaft 27.
  • the aforementioned further machine or device may comprise an automatically actuated paint spraying apparatus (not shown) of conventional form which will emit a spray of paint at the appropriate moment when the article is aligned with the apparatus, the apparatus being actuated as above-described by the means 24.
  • the paint spraying apparatus will be disposed ahead of the nozzle 14 by a distance such that the conveyor will traverse said distance in a time which corresponds to the time taken by an actuator element to pass between the arm 22 and the means 24.
  • an article detecting device for detecting the presence or absence of articles travelling along the conveyor, said device comprising a pivotally mounted vane, at least one nozzle adapted to be connected to a supply of pressurised fluid whereby in use at least one stream of such fluid can be directed towards said vane, the member and the nozzle being arranged so that articles to be detected will pass between the member and the nozzle, the vane being movable between a first position to which it is deflected by the stream of pressurised fluid impinging on it in the absence of an article between the vane and the nozzle and a second position which it assumes when said stream of pressurised fluid is interrupted by the presence of an article between the vane and the nozzle, there being provided a support drivingly connected to said conveyor so as to be rotatable thereby, and a plurality of actuator elements carried by said support so as to be movable in a closed path and in a spaced relationship at a speed having a predetermined relationship to the speed of the conveyor, each actuator
  • An article detecting device as claimed in claim 1 wherein there is provided an arm which is movable, by movement of the vane to its second position, into engagement with an actuator element so as to displace the latter into its operative position, said movable arm being resilient or resiliently mounted so as to be biased towards an imperative position in which it is not adapted to engage an actuator element.
  • An article detecting device as claimed in claim 1 wherein means are provided for re-setting to its inoperative position each actuator element which has been moved to an operative position after it has engaged said means for carrying out an operation on an article advanced along said conveyor.
  • An article detecting device as claimed in claim 1 wherein there is provided a tube which is disposed between said nozzle and said vane, one end of said tube being arranged to receive a stream of pressurised fluid from the nozzle when an article is not present between the nozzle and said end of the tube and the other end of the tube being arranged to direct such a stream of pressurised fluid onto the vane.
