Abstract

A food processing system includes a driving pulley, a driven pulley, a motor, a belt, and an actuator. The motor is configured to rotate the driving pulley. The belt is connected with the driving pulley and the driven pulley. The driving pulley is configured to rotate the belt. The belt is configured to rotate the driven pulley. The actuator is connected with the driven pulley. The actuator is configured to move the driven pulley relative to the belt between an extended position and a retracted position.

First claim

The invention claimed is:

1. A food processing system comprising:
a driving pulley;
a driven pulley;
a motor to rotate the driving pulley;
a belt connected with the driving pulley and the driven pulley, the driving pulley to rotate the belt, the belt to rotate the driven pulley; and
an actuator connected with the driven pulley, the actuator to move the driven pulley relative to the belt between an extended position and a retracted position;
wherein the driving pulley comprises a driving pulley belt pocket, the driving pulley belt pocket comprising first, second, and third driving pulley belt pocket surfaces, the second and third driving pulley belt pocket surfaces opposed to one another and extending in a traverse orientation from separate ends of the first driving pulley belt pocket surface, the belt disposed on the first driving pulley belt pocket surface between the second and third driving pulley belt pocket surfaces, a width of the first driving pulley belt pocket surface sized larger than a width of the belt to allow relative movement between the belt and the first driving pulley belt pocket surface when the driven pulley moves between the extended and retracted positions;
wherein the driven pulley comprises a driven pulley belt pocket, the driven pulley belt pocket comprising first, second, and third driven pulley belt pocket surfaces, the second and third driven pulley belt pocket surfaces opposed to one another and extending in a traverse orientation from separate ends of the first driven pulley belt pocket surface, the belt disposed on the first driven pulley belt pocket surface between the second and third driven pulley belt pocket surfaces, a width of the first driven pulley belt pocket surface sized larger than a width of the belt to allow relative movement between the belt and the first driven pulley belt pocket surface when the driven pulley moves between the extended and retracted positions;
wherein the belt is configured to walk back and forth relative to and along the width of the first driving pulley belt pocket surface and relative to and along the width of the first driven pulley belt pocket surface when the driven pulley is moved back and forth between the extended and retracted positions;
wherein the actuator comprises at least one arm directly connected to a main housing, a spindle housing fixedly attached to the main housing, a spindle rotatably disposed within and relative to the spindle housing, the driven pulley fixedly attached to the spindle, the at least one arm configured to move the main housing, the spindle housing, and the spindle relative to the belt when the driven pulley moves between the extended and retracted positions.

2. The food processing system of claim 1 further comprising a food processing device connected with the spindle, wherein the food processing device is disposed further away from the belt when the driven pulley is in the extended position than when the driven pulley is in the retracted position.

3. The food processing system of claim 2 wherein the food processing device is a cutting member.

4. The food processing system of claim 1 wherein the width of the first driven pulley belt pocket surface is at least 1.2 times larger than the width of the belt to allow relative movement between the belt and the first driven pulley belt pocket surface when the driven pulley moves between the extended and retracted positions.

5. The food processing system of claim 1 wherein the width of the first driving pulley belt pocket surface is at least 1.3 times larger than the width of the belt to allow relative movement between the belt and the first driving pulley belt pocket surface when the driven pulley moves between the extended and retracted positions.

6. The food processing system of claim 1 wherein a first end of the at least one arm is directly connected to the main housing and a second end of the at least one arm is directly connected to the actuator.

7. The food processing system of claim 6 further comprising a housing of the food processing system, wherein the at least one arm is attached to the housing of the food processing system at a pivot point between the first and the second ends about which the at least one arm pivots as the driven pulley moves between the extended and retracted positions.

8. The food processing system of claim 1 wherein the second and third driving pulley belt pocket surfaces have respective diameters which are larger than a diameter of the first driving pulley belt pocket surface, and the second and third driven pulley belt pocket surfaces have respective diameters which are larger than a diameter of the first driven pulley belt pocket surface.

9. A food processing system comprising:
a driving pulley;
a driven pulley;
a food processing device connected with the driven pulley;
a motor to rotate the driving pulley;
a belt connected with the driving pulley and the driven pulley, the driving pulley to rotate the belt, the belt to rotate the driven pulley and the food processing device connected with the driven pulley; and
an actuator connected with the driven pulley and the food processing device, the actuator to move the driven pulley and the food processing device connected with the driven pulley relative to the belt when the driven pulley is moved between an extended position and a retracted position, wherein the food processing device is disposed further away from the belt when the driven pulley is in the extended position than when the driven pulley is in the retracted position;
wherein the driving pulley comprises a driving pulley belt pocket, the driving pulley belt pocket comprising first, second, and third driving pulley belt pocket surfaces, the second and third driving pulley belt pocket surfaces opposed to one another and extending in a traverse orientation from separate ends of the first driving pulley belt pocket surface, the belt disposed on the first driving pulley belt pocket surface between the second and third driving pulley belt pocket surfaces, a width of the first driving pulley belt pocket surface sized larger than a width of the belt to allow relative movement between the belt and the first driving pulley belt pocket surface when the driven pulley moves between the extended and retracted positions;
wherein the driven pulley comprises a driven pulley belt pocket, the driven pulley belt pocket comprising first, second, and third driven pulley belt pocket surfaces, the second and third driven pulley belt pocket surfaces opposed to one another and extending in a traverse orientation from separate ends of the first driven pulley belt pocket surface, the belt disposed on the first driven pulley belt pocket surface between the second and third driven pulley belt pocket surfaces, a width of the first driven pulley belt pocket surface sized larger than a width of the belt to allow relative movement between the belt and the first driven pulley belt pocket surface when the driven pulley moves between the extended and retracted positions;
wherein the belt is configured to walk back and forth relative to and along the width of the first driving pulley belt pocket surface and relative to and along the width of the first driven pulley belt pocket surface when the driven pulley is moved back and forth between the extended and retracted positions;
wherein the actuator comprises at least one arm directly connected to a main housing, a spindle housing fixedly attached to the main housing, a spindle rotatably disposed within and relative to the spindle housing, the driven pulley fixedly attached to the spindle, the at least one arm configured to move the main housing, the spindle housing, and the spindle relative to the belt when the driven pulley moves b
