Abstract
An auto-centering apparatus and method of auto-centering and dividing a cheese loaf into equal cheese portions is disclosed wherein the cheese loaf is loaded on to a bottom conveyor that centers the cheese along the cutting harp centerline and equally divides the cheese loaf to provide substantially equally sized cheese portions.
Claims19
An apparatus for auto centering and dividing a cheese loaf having a height, a width defined by opposing side surfaces and a length, the apparatus comprising:
- a support frame;
- a bottom conveyor secured to the support frame having a continuous belt including first and second side edges and a vertical centerline positioned at the midpoint between the first and second side edges of the belt, the belt having an upper working surface configured to transport the cheese loaf from a front end to a back end thereof;
- a first positioning mechanism secured to a bottom portion of the support frame and extending a portion of the length of the upper working surface of the bottom conveyor, the first positioning mechanism comprising first and second pivotally interconnected arms coupled to a single pneumatic cylinder and extending vertically in the same plane, the arms configured in a mirror image fashion and configured to straddle opposite side edges of the belt, wherein the arms pivot about a pivot point that is substantially vertically aligned with the centerline of the continuous belt, wherein upper portions of each of the interconnected arms are configured to engage the cheese loaf, wherein each arm moves simultaneously the same distance dimension toward the centerline and away from the centerline of the belt;
- and
- a cutting harp located close adjacent to the rear end of the bottom conveyor, the cutting harp including a vertical cutting wire positioned at the centerline of the belt.

An apparatus for auto centering a cheese loaf having side surfaces and an upper surface, the apparatus comprising:
- a horizontally disposed support frame;
- a bottom conveyor system secured to the frame, the bottom conveyor system having a length dimension, a width dimension defined by opposing sides and a vertical centerline between the opposing sides;
- a top conveyor having a length dimension secured to the frame and having a substantially horizontal belt that is vertically adjustable with respect to the bottom conveyor system;
- at least one centering section secured to the frame and including a least one set of pivotally interconnected arms coupled to a single pneumatic cylinder, each arm including an upper end, a middle section and a lower end extending vertically in the same plane, wherein the middle sections of each of the arms in the at least one set of arms are pivotally secured to each other at a pivot point that is vertically aligned with the centerline of the bottom conveyor system, wherein the upper end of one arm is located on one side of the bottom conveyor system and the upper end of the other arm of the set of pivotally interconnected arms is located on the opposing, other side of the bottom conveyor system with each set of arms configured to move simultaneously;
- a first set of spaced apart and longitudinally aligned rollers secured to the upper portion of one of the arms of the at least one centering section;
- a second set of spaced apart and longitudinally aligned rollers secured to the upper portion of the other arm of the set of pivotally interconnected arms, wherein the first and second set of rollers are configured a distance away from each other, the midpoint of the distance being substantially the same location as the centerline of the belt, wherein the first and second rollers are configurable between a first position in which each set of rollers is spaced apart from the side surfaces of the cheese loaf and a second position in which each set of rollers contacts the side surfaces of the cheese loaf;
- and
- a cutting harp including at least one cutting wire secured to the frame at a rear end of the bottom conveyor system.
5 more elements
An auto-centering and cutting apparatus for use with a cheese loaf having side surfaces, the apparatus comprising:
- a horizontally disposed support frame;
- a bottom conveyor system secured to the frame and having an upwardly disposed working surface including a front end, a rear end, a length therebetween, and a vertical centerline disposed at the midpoint between first and second opposing sides of the working surface;
- a top conveyor system secured to the frame and having an downwardly disposed working surface that is space apart from and vertically adjustable with respect to the upper working surface of the bottom conveyor system;
- a first set of roller side rails including a first roller side rail positioned on the first side of the working surface of the bottom conveyor system and a second roller side rail positioned on the second side of the working surface of the bottom conveyor system, the first and second roller side rails each having a bottom portion that is pivotally interconnected at a pivot point that is substantially vertically aligned with the vertical centerline of the bottom conveyor system and coupled to a single pneumatic cylinder, wherein the bottom portion of each of the first and second roller side rails is aligned vertically in the same plane, and wherein each bottom portion move simultaneously the same distance, wherein the first set of roller side rails extends from the front end of the bottom conveyor to a distance along the length of the bottom conveyor and wherein the first and second roller side rails are configurable between a first position in which each of the first and second roller side rails is spaced apart from the side surfaces of the cheese loaf and a second position in which each set of rollers contacts the side surfaces of the cheese loaf;
- and
- a cutting harp including at least one vertical cutting wire removably secured to the frame at a position close adjacent to the rear end of the bottom conveyor system.
