Abstract

An apparatus is provided for separating a flow of golf balls into a first set of golf balls which meet predetermined specifications and a second set of golf balls which do not meet specifications. The apparatus includes a first elongated cylinder having a central axis positioned at an angle with respect to the horizontal. The elongated cylinder has an open lower end, an open upper end and an interior diameter to allow for the rolling of golf balls of the first set to move therethrough and out of the lower end. A large aperture is formed in an upper surface of the elongated cylinder at a central extent thereof. The interior surface of the elongated cylinder is of an increased diameter between central extent thereof and the upper end thereof. A supplemental small aperture is formed in the upper surface of the elongated cylinder offset from the uppermost extent thereof. The supplemental small aperture is formed at an angle with regard to the axis of the elongated cylinder. A short delivery cylinder is provided having a vertical axis and being formed with a lower end coupled to the large aperture and an upper end for delivering golf balls to be separated.

Claims

1. An apparatus for separating a flow of golf balls into a first set of golf balls which meet predetermined specifications and a second set of golf balls which do not meet specifications comprising:

a first elongated cylinder having a central axis positioned at an angle with respect to the horizontal, the elongated cylinder having an open lower end and an open upper end in coaxial alignment with the lower end and having an interior diameter to allow for the rolling of golf balls of the first set to move therethrough and out of the lower end, a large aperture formed in an upper surface of the elongated cylinder at a central extent thereof, the interior surface of the elongated cylinder being of an increased diameter between the central extent thereof and the upper end thereof, a supplemental small aperture formed in the upper surface of the elongated cylinder offset from the uppermost extent thereof, the supplemental small aperture being formed at an angle with regard to the axis of the elongated cylinder;

a short delivery cylinder having a vertical axis and being formed with a lower end coupled to the large aperture and an upper end for delivering golf balls to be separated; and

a source of compressed fluid coupled to the small aperture adapted to inject a stream of fluid into the elongated cylinder in a direction toward the upper end to drive a golf ball of the second set in the elongated cylinder outwardly of the elongated cylinder.

2. An apparatus for separating a flow of golf balls into a first set of golf balls which meet predetermined specifications and a second set of golf balls which do not meet specifications comprising:

a first elongated cylinder having a central axis positioned at an angle with respect to the horizontal, the elongated cylinder having an open lower end and an open upper end and having an interior diameter to allow for the rolling of golf balls of the first set to move therethrough and out of the lower end, a large aperture formed in an upper surface of the elongated cylinder at a central extent thereof, the interior surface of the elongated cylinder being of an increased diameter between the central extent thereof and the upper end thereof, a supplemental small aperture formed in the upper surface of the elongated cylinder offset from the uppermost extent thereof, the supplemental small aperture being formed at an angle with regard to the axis of the elongated cylinder;

a short delivery cylinder having a vertical axis and being formed with a lower end coupled to the large aperture and an upper end for delivering golf balls to be separated;

a source of compressed fluid coupled to the small aperture and adapted to inject a stream of fluid into the elongated cylinder in a direction toward the upper end to drive a golf ball of the second set in the elongated cylinder outwardly of the elongated cylinder; and

sensor means for sensing the flow of golf balls of the first set through the lower end of the elongated cylinder and to activate the source of compressed air in the event that a golf ball of the second set does not move through the lower end of the elongated cylinder in a timely manner to thereby drive such golf ball out of the upper end.

3. An apparatus for separating a flow of golf balls into a first set of golf balls which meet predetermined specifications including size, burrs, blisters and long gates and a second set of golf balls which do not meet specifications comprising, in combination:

a first elongated cylinder having a primary axis positioned at an angle of about 10 degrees with respect to the horizontal, the elongated cylinder having an open lower end and an open upper end and having an interior diameter of about 2.25 inches to allow for the rolling of golf balls of the first set to move therethrough and out of the lower end, a large aperture formed in an upper surface of the elongated cylinder at a central extent thereof to form a long lower region and a short upper region, the interior surface of the elongated cylinder being of an increasing diameter from the central extent thereof to the upper end thereof, a pair of supplemental small apertures formed in the upper surface of the elongated cylinder offset from the uppermost region thereof, the supplemental small apertures being formed at an angle of 30 degrees with regard to the axis of the elongated cylinder;

a short delivery cylinder having a vertical axis and having an diameter of about 2.76 inches and being formed with a lower end coupled to the large aperture of the elongated cylinder and having an upper end with a flange for coupling with a machine for delivering at a predetermined feed rate golf balls to be separated;

a ramp for the delivering of golf balls into the delivery cylinder;

a source of compressed air coupled to the small apertures adapted to inject a stream of air into the elongated cylinder in a direction toward the upper end of the elongated cylinder to drive a golf ball of the second set in the elongated cylinder outwardly of the elongated cylinder; and

a sensor adjacent to the output end of the elongated cylinder to sense the flow of golf balls of the first set through the lower end of the elongated cylinder and to activate the source of compressed air in the event that a golf ball of the second set does not move through the lower end of the elongated cylinder in a timely manner to thereby drive such golf ball out of the upper end.
