DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a method and apparatus for sorting round objects, and particularly for sorting out round objects which do not meet a given minimum or maximum dimension.
SUMMARY OF THE INVENTION
The object of the invention has been to achieve a simple method and a simple apparatus for sorting out round objects which meet given dimension requirements, such as a predetermined minimum or maximum dimension. Also in accordance with the invention, it shall be especially possible to discover faults in roundness, such as ovality.
The method and apparatus according to the invention can be used for sorting out spherically shaped as well as circular-cylindrically shaped objects, and with regard to the latter, even such that have different diameters at different parts of the object, for example, stoppers for bottles and the like.
The invention will now be described in the form of an embodiment example, which is not to be regarded as restricting the invention, and with reference to the accompanying drawings, wherein
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic side view of a sorting apparatus in accordance with the present invention, for sorting cylindrical stoppers having two different diameters:
FIG. 2 is a section A--A through a part of the apparatus in FIG. 1:
FIG. 3 is a section B--B through the part illustrated in FIG. 2:
FIG. 4 illustrates a part of the inventive apparatus in a different embodiment; and
FIG. 5 is a section through the part illustrated in FIG. 4.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT (S)
In FIG. 1 there is illustrated a sorting apparatus in accordance with the present invention. The objects to be sorted are stoppers 1, and as will be seen from the Figure they have a substantially cylindrical shape, where one portion of the stopper has a larger diameter than the other portion. Such a stopper may be used for closing off bottles. Facing in the right direction these stoppers are placed on a chute 2, where they move under the action of gravity towards a first sorter 3.
This sorter includes a paddlewheel-like sorting member, provided in its outer circumferential region with fixed dogs 4. The dogs 4 are substantially radially disposed and extend a distance in towards the center of the member, as far as a centrally arranged opening 5 in it. The dogs 4 are also mutually spaced for accomodating and carrying the stoppers 1. The sorting member rotates continuously in the direction of the arrow 6, and a stopper 1 that has left the chute 2 and has come between two adjacent dogs 4 thus rotates with the sorting member. The stopper also moves by gravity towards the center of the sorting member and towards the central opening 5. The mutual spacing of the dogs is, however, such that the width of the opening towards the central opening 5 between two dogs is equal to the given minimum dimension 7 for the stoppers. The stoppers that do not comply with this dimension 7 fall down between respective adjacent dogs 5 into the central opening 5, and via a reject chute 8 are taken out from the apparatus in the direction of arrow 9. The stoppers meeting the given dimension 7 will remain between their respective dog pairs and are conveyed in the direction of the arrow 6 as the sorting member continues to rotate. A fence 10 is arranged exterior to the circumference of the sorting member 9 to prevent the stoppers from falling down at an undesired place, and they are taken instead to a transfer device 11 for being led via it to a second sorter.
The transfer device 11 can be of a simple construction, such as a simple chute, which leads the stoppers 1, after they have passed through the first sorter and have met the minimum dimension, to the second sorter 12.
The second sorter 12 includes a disc 13 carrying two mutually movable members 14 and 15, in contrast to the fixed dogs 4, as will be explained below. The gauging members 14 and 15 together form a channel 16, along which the stoppers not exceeding a given maximum dimension can move. These stoppers roll by gr
