Abstract

Methods and machines for cutting solid and semisolid materials, for example, food products. The machine has a dicing unit that has a feed drum, circular cutter, and cross-cutter each individually rotatably mounted to a support structure by cantilevered shafts. The machine further has a knife for producing slices of a solid or semisolid material, circular knives on the circular cutter to cut the slices into strips, and cross-cut knives on the cross-cutter to dice the strips. The machine also has a stripper plate for removing the strips from the circular cutter, and an outboard support assembly for supporting and radially centering outboard ends of the shafts of the feed drum, circular cutter, and cross-cutter and for supporting and securing the stripper plate relative thereto.

First claim

The invention claimed is:

1. A machine for dicing solid and semisolid materials, the machine comprising:
a support structure;
means interconnected with the support structure for producing slices by slicing a solid or semisolid material;
a circular cutter and a cross-cutter that are each individually rotatably mounted to the support structure by cantilevered shafts, the shafts of the circular cutter and the cross-cutter each having an outboard end;
circular knives on the circular cutter that are adapted and arranged to cut into strips the slices produced by the slice-producing means;
cross-cut knives on the cross-cutter that are adapted and arranged to dice the strips produced by the circular knives;
a stripper plate having a first edge between the circular cutter and the cross-cutter for removing the strips from the circular cutter, the stripper plate defining a second edge adapted to ensure complete dicing of the strips by the cross-cut knives of the cross-cutter;
means for adjusting the placement and proximity of the second edge relative to the cross-cut knives, said adjusting means comprises shimming means; and outboard support means
for supporting and radially centering the outboard ends of the shafts of at least the circular cutter and the cross-cutter and for supporting and securing the stripper plate relative thereto.

2. The machine of claim 1 , wherein the stripper plate comprises slots that extend to the first edge, and individual edges of the first edge between adjacent pairs of the slots remove the strips from between adjacent pairs of the circular knives.

3. The machine of claim 1 , wherein the stripper plate is secured to a support bar and the adjusting means tilts the stripper plate relative to the support bar.

4. The machine of claim 3 , wherein the adjusting means comprises at least a first removable shim between the stripper plate and the support bar.

5. The machine of claim 4 , wherein the first removable shim is disposed between the stripper plate and the support bar so as to tilt the stripper plate relative to the support bar and thereby cause the second edge of the stripper plate to move toward the cross-cutter and reduce a distance between the second edge and the cross-cut knives of the cross-cutter.

6. The machine of claim 5 , wherein the adjusting means further comprises a second removable shim the shim adapted to be disposed between the stripper plate and the support bar so as increase the tilt the stripper plate relative to the support bar.

7. The machine of claim 5 , wherein the adjusting means further comprises a recess defined by at least one of the stripper plate and the support bar and in which the first removable shim is disposed.

8. The machine of claim 1 , wherein the stripper plate is secured to a support bar, the support bar is secured and cantilevered from the support structure, and the outboard support means comprises a support plate secured to an outboard end of the support bar.

9. The machine of claim 8 , wherein the outboard support means further comprises cups mounted to the support plate, and the cups have female tapered features engaged with complementary male tapered features associated with the shafts of the circular cutter and the cross-cutter so as to support and radially center the shafts of the circular cutter and the cross-cutter.

10. The machine of claim 9 , wherein the outboard support means, the support plate thereof, and the cups mounted thereto are installed on the machine and removable from the machine as a complete unit.

11. The machine of claim 10 , wherein at least the circular cutter and the cross-cutter are mounted to the support structure such that removal of the outboard support means from the machine results in at least the circular cutter and the cross-cutter being cantilevered from the support structure.

12. The machine of claim 1 , wherein the solid or semisolid material is a food product.

13. The machine of claim 1 , wherein the solid or semisolid material is a solid frozen food product.

14. A method of using the machine of claim 1 , the method comprising installing the outboard support means on and removing the outboard support means from the machine as a complete unit and independently of the circular cutter and the cross-cutter.

15. The method of claim 14 , wherein the outboard support means comprises a support plate, the stripper plate is secured to a support bar that is secured and cantilevered from the support structure, and the step of installing the outboard support means on the machine comprises securing the support plate to an outboard end of the support bar.
