Abstract

A loaf end trimming station for a high speed food loaf slicing machine, includes a frame, a first knife and a second knife spaced apart along the frame and oriented in positions corresponding to a lead end trimming location and a trailing end trimming location of a food loaf. The trimming station includes a loaf cutting support for receiving the loaf, and a motive mechanism to move the loaf cutting support toward the knives to trim ends off of the loaf. The trimming station includes a loaf staging support, wherein the loaf cutting support deposits the loaves on the loaf staging support after being trimmed by the knives. The loaf staging support is tiltable between a staging position to collect trimmed loaves and a loading position to deliver trimmed loaves to the high speed food loaf slicing machine.

Claims

1. An improved high speed food loaf slicing machine, comprising:

a slicing station including a knife blade and a knife blade drive driving the knife blade along a predetermined cutting path, and loaf support means for supporting a food loaf into the slicing station for repetitive slicing of said loaf by the knife blade;

a loaf feed drive for advancing the food loaf along the loaf path at a feed rate; and

a trimming station located adjacent to said slicing station and comprising a frame, a first knife and a second knife spaced apart along said frame and oriented in positions corresponding to a lead end trimming location and a trailing end trimming location of a food loaf, a loaf cutting support for receiving said loaf, and a motive mechanism to move said loaf cutting support toward said knives to trim end portions off of said loaf to provide a trimmed loaf, and a delivery mechanism for delivering said trimmed loaf to said slicing station,

wherein said loaf cutting support is pivotally mounted on said frame, and said knives are fixedly mounted to said frame, and wherein said motive mechanism comprises a pneumatic cylinder connected between said loaf cutting support and said frame, a change in length of said pneumatic cylinder pivoting said loaf cutting support to drive said knives through said loaf held thereon.

2. An improved high speed food loaf slicing machine according to claim 1, wherein said delivery mechanism comprises a loaf staging support wherein said loaf cutting support deposits the loaves on said loaf staging support after being trimmed by said knives, said loaf staging support movable between a staging position to collect trimmed loaves and a loading position to deliver trimmed loaves to said cutting path.

3. An improved high speed food loaf slicing machine according to claim 1, wherein said cutting path holds plural loaves side-by-side, and comprising plural loaf feed drives that drive said loaves independently into the cutting plane.

4. An improved high speed food loaf slicing machine according to claim 3, wherein said slicing station comprises a loaf loading tray for receiving loaves from said staging support, a loading mechanism for moving said loaf loading tray to a position adjacent to said cutting path, and a displacement mechanism for moving said loaves from said loaf loading tray to said cutting path.

5. An improved high speed food loaf slicing machine according to claim 1, wherein said knives are adjustable in position on said frame along a direction along the length of said loaf held on said loaf cutting support.

6. An improved high speed food loaf slicing machine according to claim 1, comprising an end stop on said loaf cutting support, said end stop arranged to abut an end of a loaf set on said loaf cutting support, said end stop being adjustable in position on said loaf cutting support along a direction along a length of said loaf held on said loaf cutting support.

7. An improved high speed food loaf slicing machine according to claim 1, wherein said knives are non-rotational, fixed blades.

8. An improved high speed food loaf slicing machine, comprising:

a slicing station including a knife blade and a knife blade drive driving the knife blade along a predetermined cutting path, and loaf support means for supporting a food loaf into the slicing station for repetitive slicing of said loaf by the knife blade;

a loaf feed drive for advancing the food loaf along the loaf path at a feed rate; and

a trimming station located adjacent to said slicing station and comprising a frame, a first knife and a second knife spaced apart along said frame and oriented in positions corresponding to a lead end trimming location and a trailing end trimming location of a food loaf, a loaf cutting support for receiving said loaf, and a motive mechanism to move said loaf cutting support toward said knives to trim end portions off of said loaf to provide a trimmed loaf, and a delivery mechanism for delivering said trimmed loaf to said slicing station; and

wherein said loaf cutting support is movably mounted on said frame, and said knives are mounted in a fixed position on said frame, and wherein said motive mechanism comprises a pneumatic cylinder connected between said loaf cutting support and said frame, a change in length of said pneumatic cylinder pivoting said loaf cutting support to drive said knives through said loaf held thereon; and

wherein said knives are adjustable in position on said frame along a direction along the length of said loaf held on said loaf cutting support.

9. An improved high speed food loaf slicing machine according to claim 8, comprising an end stop on said loaf cutting support, said end stop arranged to abut an end of a loaf set on said loaf cutting support, said end stop being adjustable in position on said loaf cutting support along a direction along a length of said loaf held on said loaf cutting support.

11. A trimming apparatus for food loaves, comprising:

a frame;

a first knife and a second knife spaced apart along said frame and oriented in positions corresponding to a lead end trimming location and a trailing end trimming location of a food loaf;

a loaf cutting support for receiving said loaf; and

a motive mechanism to move said loaf cutting support toward said knives to trim end portions off of said loaf; and

a loaf staging support wherein said loaf cutting support deposits the loaves on said loaf staging support after being trimmed by said knives, said loaf staging support movable between a staging position to collect trimmed loaves and a loading position to discharge loaves;

wherein said loaf cutting support is pivotally mounted on said frame, and said knives are mounted to said frame, and wherein said motive mechanism comprises a pneumatic cylinder connected between said loaf cutting support and said frame, a change in length of said pneumatic cylinder pivoting said loaf cutting support to drive said knives through said loaf held thereon;

wherein said knives are adjustable in position on said frame along a direction along the length of said loaf held on said loaf cutting support; and

comprising an end stop on said loaf cutting support, said end stop arranged to abut an end of a loaf set on said loaf cutting support, said end stop being adjustable in position on said loaf cutting support along a direction along a length of said loaf held on said loaf cutting support.

12. A trimming apparatus according to claim 11, wherein said knives are non-rotational fixed blades.

13. An improved high speed food loaf slicing machine, comprising:

a slicing station including a knife blade and a knife blade drive driving the knife blade along a predetermined cutting path, and loaf support means for supporting a food loaf into the slicing station for repetitive slicing of said loaf by the knife blade;

a loaf feed drive for advancing the food loaf along the loaf path at a feed rate; and

a trimming station located adjacent to said slicing station and comprising a frame, a first knife and a second knife spaced apart along said frame and oriented in positions corresponding to a lead end trimming location and a trailing end trimming location of a food loaf, a loaf cutting support for receiving said loaf, and a motive mechanism to move said loaf cutting support toward said knives to trim end portions off of said loaf to provide a trimmed loaf, and a delivery mechanism for delivering said trimmed loaf to said slicing station; and
