Definitions

  • the present invention relates to an apparatus for non- destructive inspection of cylindrical containers for liquid products. More particularly, the invention concerns an apparatus for X- ray inspection of cylindrical containers, such as glass bottles and vessels for liquid foodstuffs such as wines and other drinks.
  • Such apparatuses comprise suitable X-ray generators/ detectors and the relevant control circuitry. Inspection of foodstuffs containers is intended to detect the presence of possible contaminants within the container. Indeed, it is possible that during processing and bottling a particle or fragment of an alien substance, generally of higher specific weight than the liquid in which by chance it is present, becomes introduced inside the container.
  • cylindrical containers such as glass bottles for drinks often have an inward curved bottom defining an annular zone with closely spaced side walls, difficult to be inspected by X-ray units. Any glass fragment or other object with higher specific weight than the liquid will become deposited by gravity onto said annulus at the bottle bottom.
  • Different solutions to the problem of how to detect the presence of said fragments in a container with an inward curved bottom have been proposed in the past.
  • an X-ray inspection apparatus comprises a vertically developing device for transferring the containers or bottles, which device is arranged to upset the containers about an axis perpendicular to the advance direction, on a plane parallel to the advance direction.
  • the above device is provided with two half-circular curved sections separated by a rectilinear section along which the X-ray unit is located.
  • the first curved section of the device performs the bottle rotation by 180°, so as to present them in upset condition through the X-ray unit, whereas the second curved section brings again the bottles to the upright position.
  • a drawback of the device of the above patent is that the bottle is to be upset in order to be inspected, and this is time consuming. In other prior art devices, the bottles are shaken so that contaminants deposited on the bottom become suspended and their presence can be detected.
  • the apparatus comprises means for transferring the containers through the X-ray unit and arranged to bring the containers to an inclined position about the advance direction when said containers are being conveyed through said X- ray unit, while keeping a substantially rectilinear and horizontal advance direction.
  • the containers are inclined about the advance direction by an angle which is a function of the shape of their curved bottom and of the difference of specific weight between contaminants and the liquid being contained, so as to achieve a quick displacement of the contaminants towards a region more readily accessible by the X-ray unit, with a minimum inclination of the containers.
  • the known chain conveyors can be used as means for transferring the containers in inclined position through the X-ray unit.
  • chain conveyor An example of chain conveyor is disclosed in PCT patent application WO 99/ 15443 by FLEXLINK SYSTEMS AB.
  • the chain conveyor according to the teaching of said PCT application comprises a chain of articulately interconnected plane link members running on suitable guides.

  • inspection apparatus 1 comprises a plurality of supports 2 on which there is mounted a linear conveyor 10 consisting of two facing chain conveyors 11 , 12 with vertical plane. Thanks to the two chain conveyors, cylindrical containers 13 are conveyed in a rectilinear direction, parallel to ground. Said cylindrical containers 13 may be for instance, glass bottles having a bottom 13' curved towards the bottle inside and defining an annular region 13" where contaminants, if any, present within bottle 13 become deposited.
  • four supports 2 are provided, two of which support the end portions of conveyor 10 while the other two support the central portion of conveyor 10. If however the conveyor length makes it necessary, the conveyor can be supported by a greater number of supports.
  • Each of the two chain conveyors 1 1, 12 comprises a chain 14, consisting of a plurality of articulately interconnected plane links, made of a material suitable for laterally holding glass bottles 13 during conveyance.
  • Each chain conveyor 11, 12 is driven by a driving unit 16 including a motor reducer.
  • chain conveyors 1 1 , 12 are each arranged with vertical plane so as to take and release bottles 13 in upright position.
  • central portion 10' is provided where chain conveyors 11, 12 follow a twisted path so as to take an inclined position while remaining parallel with each other, the conveyors resuming the vertical position while following the inverse path.
  • central supports 2 are so constructed as to allow supporting chain conveyors 11 , 12 located at different heights.
  • bottles 13 pass from the upright position to the inclined position.
  • the X-ray unit comprising at least one emitter 18 and at least one detector 19 for inspection of the contents of bottles 13, is located in correspondence with the twisted conveyor portion in order to inspect the bottles while in inclined position.

  • bottle 13 is inclined for inspection by an angle ⁇ of about 80°.
  • the inclination to be given to the bottle will be in the range 90° ⁇ 10°; yet, by exploiting the same inventive principle, conveyor capable of conferring an inclination by an angle in the range 0° to 180° can be provided.
  • the twisted paths of chain conveyors 1 1 , 12 will entail upsetting the running plane thereof by an angle of 180° and, consequently, the exchange of the mutual positions of chain conveyors 11, 12.
  • the inclination to be given to bottles 13 is predetermined depending on the shape of bottom 13' thereof and the specific weight difference between the contaminant and the liquid in the bottle, so as to obtain a quick displacement of contaminants from annular region 13" to region A by giving the bottles an inclination as small as possible.
  • emitter 18 and detector 19 could be modified depending on the inclination given to the bottles, so as to inspect a bottle region, other than region A, where contaminants, if any, will become deposited depending on the inclination.

Abstract

L'invention concerne un appareil de contrôle non destructif aux rayons X pour contenants (13) cylindriques de produits liquides. Cet appareil comprend des moyens (10) destinés à acheminer lesdits contenants cylindriques dans une direction sensiblement rectiligne. Selon l'invention, ces moyens font prendre aux contenants (13) une position inclinée par rapport au sens de l'avancement lorsqu'ils traversent l'appareil à rayons X.
