Abstract

A food slicing apparatus and components where the apparatus includes a frame and a pivotally mounted carriage. The frame mounts a height adjustable conveyor system while the carriage hosts a latch for a slice thickness adjustment cam. The carriage also supports a drive system which precisely moves a food transporting tube assembly over a base, such as pizza dough, while food is cut by a laterally moving blade mounted around two drums, one of which is adjustable to change tension in the blade. The blade is further supported by a blade guide which also guides the sliced food to the pizza dough base. The drive system includes a servomotor, a group of gears, a crank connected to the gears, a cam roller and a cam follower plate with a slot. The cam follower plate is connected by a quick connect and disconnect connector to the food tube assembly. The result is a compact, efficient slicing apparatus with a small footprint that is usable in a food processing line. The apparatus is easy to clean and the food tube assembly is easily exchanged with an assembly having a different arrangement of the food tubes.

Claims

1. A drive system for a food slicing apparatus comprising:

a precision motion creator;

gears operatively connected to said motion creator;

a link having first and second end portions, said first end portion being operatively mounted to said gears;

a cam element mounted to said second end portion of said link;

a cam follower element including a slot for receiving said cam element; and

a quick connect and disconnect connector for engaging said cam follower element and a food transporting assembly.

2. The apparatus as claimed in claim 1 wherein:

said cam follower element includes a connector opening; and

said connector includes pins for engaging said opening of said cam follower element and an opening in the food carrier assembly.

3. The apparatus as claimed in claim 2 wherein:

said cam follower element includes oppositely disposed grooves to facilitate mounting on guide rails.

4. The apparatus as claimed in claim 3 wherein:

said motion creator accelerates said cam follower element to a predetermined velocity and thereafter decelerates said cam follower element.

5. A slicing apparatus for a product processing line comprising:

a frame;

a conveyor system mounted to said frame, said conveyor system for forming a first path along which bases move;

a cutting blade mounted on structure for moving generally perpendicular to said first path;

a tube assembly connected to said frame for moving along a second path parallel to and above said first path and for moving items to be sliced passed said cutting blade;

a compact drive system connected to said tube assembly for moving said tube assembly, said drive system including a precision motion generator and a connected crank; and

a control system for cycling said drive system in a predetermined manner; and

wherein

said drive system includes a group of gears, a cam and a cam follower plate, said gears being driven by a servomotor;

said crank has first and second end portions, said first end portion being operatively mounted to said gears;

said cam being mounted to said second end portion of said crank; and

said cam follower plate having a slot for receiving said cam.

6. The apparatus as claimed in claim 5 including:

a quick connect and disconnect connector engaging said tube assembly and said drive system.

7. The apparatus as claimed in claim 5 including:

a connector having a plurality of pins; and

wherein pin receiving holes are formed in said tube assembly and in said drive system.

8. A drive system for a food slicing apparatus, where said apparatus includes a conveyor system for moving a series of bases, a pair of rails and a control system, said drive system comprising:

a precision motion creator located above said conveyor system;

gears operatively connected to said motion creator;

a link having first and second end portions, said first end portion being operatively mounted to said gears;

a cam mounted to said second end portion of said link;

a cam follower movable along said pair of rails, said cam follower including a slot for receiving said cam; and

a connector for engaging said cam follower and a food transporting assembly, said food transporting assembly also being movable along said pair of rails whereby food product transported by said food carrier assembly is deposited upon said moving bases.

9. The apparatus as claimed in claim 8 wherein:

said motion creator causes said cam follower and said food transporting assembly to move at the same velocity as the bases on said conveyor system.

10. The apparatus as claimed in claim 9 wherein:

said motion creator accelerates and decelerates said cam follower, said food transporting assembly and said connector.

11. A slicing apparatus for a product processing line comprising:

a frame;

a conveyor system mounted to said frame, said conveyor system for forming a first path along which bases move;

a cutting blade mounted to move across said first path;

a tube assembly connected to said frame to move along a second path parallel to and above said first path and to move items to be sliced passed said cutting blade;

a compact drive system connected to said tube assembly to move said tube assembly; and

a control system to cycle said drive system in a predetermined manner;

wherein said drive system includes a motor, a crank connected to the motor, and a plate having a slot with a predetermined geometry;

said crank includes first and second end portions, said first end portion being operatively connected to said motor and said second end portion being connected to a cam; and

said cam is disposed in said slot and is restrained to move in a predetermined manner wherein said tube assembly is moved above said first path in a predetermined manner.

12. A slicing apparatus for a product processing line comprising:

a frame;

a conveyor system mounted to said frame, said conveyor system for forming a first path along which bases move;

a cutting blade mounted to structure to enable said blade to move across said first path;

a tube assembly connected to said frame to move along a second path parallel to and above said first path and to move items to be sliced passed said cutting blade;

a drive system connected to said tube assembly and positioned compactly above said cutting blade to move said tube assembly along said second path; and

a control system for cycling said drive system in a predetermined manner wherein said drive system includes a motor, a crank connected to said motor, a cam connected to said crank and a plate with a slot dimensioned to received said cam, and wherein said motor, said cam, said crank and said plate are positioned above said cutting blade.

13. The apparatus as claimed in claim 12 including:

a connector positioned between said plate and said tube assembly, said connector being positioned above said cutting blade.

14. The apparatus as claimed in claim 13 wherein:

said plate includes connector openings; and

said connector includes a first group of pins for engaging said openings of said plate and a second group of pins for engaging a food carrier assembly.

15. The apparatus as claimed in claim 13 wherein:

said slot is of predetermined geometry for causing said plate to move in a predetermined manner.
