Definitions

  • the present invention relates generally to the mass transport of articles, such as can-shaped containers from a first location at a vertical orientation to a second location at a horizontal orientation.
  • This invention can be most advantageously employed in removing ferrous, can- shaped objects from the surface of an air conveyor while feeding the objects to an air single filer. Can damage is minimized while the device provides for the metering for can-shaped objects in a positive controlled fashion.
  • the can bodies are caused to engage a number of work areas, including washing, decorating and necking stations.
  • the can bodies either travel in a moving belt, or more advantageously, upon an air conveyor consisting of a plenum having openings for the directional supply of air from the upper deck surface.
  • Devices of this nature are described in U.S. Patent 4,456,406, the disclosure of which is incorporated herein by reference.
  • Air single filers euphemistically known as doubling boxes, are exceedingly well known in can processing operations.
  • one such device is disclosed in U.S. Patent 4,182,586, the disclosure of which is hereby incorporated by reference.
  • the input or upstream end of the air single filer would be fed by a waterfall which, as the name implies, simply consists of a curved slide which transcribes a circular drum across which cans travel while rotating 90° to achieve horizontal orientation at which point they fall into the upstream end of the single filer.
  • a curved top guide surface prevents the cans from tumbling due to the small clearance between the guide and the top of the can.
  • Fig. 1 is a perspective view of the drum device of the present invention
  • Fig. 2 is a cross-sectional side view of the '• present invention.
  • Fig. 3 is a partial cross-sectional side view taken at an angle of 90° to the view of Fig. 2.
  • the present invention deals with a drum device and its method of operation.
  • the device provides for the rotation of ferrous, can-shaped objects over a curved surface from a first to a second location.
  • the device comprises a hollow, rotatable, cylindrical member, capable of rotation about a substantially horizontal, longitudinal axis.
  • a magnet assembly is located within the hollow, rotatable, cylindrical member, said magnet assembly being of a size and placement to adhere the ferrous, can-shaped objects to the surface of the hollow, rotatable, cylindrical member only from first to a second location. Means are then provided for rotating the hollow, rotatable, cylindrical member about the substantially horizontal, longitudinal axis.
  • Fig. 1 illustrates the drum device of the present invention in operation.
  • Ferrous, can-shaped objects 3 are moved along air conveyor 4 on its top surface 6 by the directional flow of air through openings 5.
  • Cans 3 thereupon engage hollow, rotatable, cylindrical member 1 at a first location and are adhered to the surface of cylindrical member l by virtue of a magnet assembly, the details of which will be discussed hereinafter.
  • Hollow, rotatable, cylindrical member 1 is caused to rotate about substantially horizontal, longitudinal axis 2 by virtue of a variable speed motor (not shown) .
  • the motor drives gear assembly 9 " which, in turn, .is coupled to a roller chain contained within roller chain housing.
  • the roller chain engages rotatable shaft 14 (Fig. 3) causing rotation of hollow, rotatable, cylindrical member 1 through bearings 13. It is an essential element of the present invention to provide a configuration whereby ferrous, can-shaped objects 3 are to be maintained by means of a magnet assembly on the surface -of rotating, cylindrical member 1 only in a specific predetermined arc of rotation, such as shown in Fig. 2.
  • the arc of rotation is approximately 90" whereby ferrous, can-shaped objects 3 are received from the surface of air conveyor 4 at a first location.
  • cans 3 are to be received from horizontal surface 6 having a substan ⁇ tially vertical axis 7.
  • the ferrous, can-shaped objects are then caused to adhere to the surface of rotating, cylindrical member 1 until the ferrous, can-shaped objects 3 reach a position whereby their collective longitudinal axes 8 are substantially horizontal.
  • an optional stripper plate 20 can be provided tangential to the surface of cylindrical member 1.
  • Magnetic assembly 11 is dimensioned along longitudinal axis 2 for a length substantially contiguous to that of hollow, rotatable, cylindrical member 1.
  • the magnetic assembly 11 is positioned along the curved interior of hollow, rotatable, cylindrical member 1 along an arc as defined by angle ⁇ to be between approximately 90° to 110°. This results in a slight "overlap" between position 1 and position 2, which enables ferrous, can-shaped objects 3 to adhere to the surface of rotating member 1 for an approximate 90° arc.
  • the drum device of the present invention can also act to regulate the flow of can-shaped objects as an alternative to gate structures of the prior art.
  • can-shaped objects 3 move from the air conveyor 4, they are captured by magnetic attraction onto the surface of rotatable, cylindrical member 1. If rotation of cylindrical member 1 stops, the flow of can-shaped objects also stops as line pressure from air conveyor 4 is not generally of sufficient strength to overdrive the drum device or to slide the can-shaped objects on the surface of rotating member 1.
  • the present invention advantageously replaces the typical prior art gate and waterfall devices. Where gates of the prior art are either open or closed, the present drum device can be adjusted from a zero to a predetermined maximum speed.

Abstract

L'invention concerne un dispositif à tambour ainsi qu'un procédé de mise en rotation d'objets (3) en forme de boîte sur une surface (4) d'un premier à un second emplacement. Ledit dispositif à tambour emploie un élément cylindrique (1) creux, rotatif orienté autour d'un axe (2) sensiblement horizontal. On a prévu un ensemble à aimant (11) à l'intérieur dudit élément cylindrique (1) creux, rotatif, se trouvant uniquement sur un segment d'orientation défini.
