Abstract

A loaf reload mechanism for a slicing machine that includes a loaf-loading position wherein during a loading operation a loaf is placed in the loaf-loading position to be engaged by a gripper and driven into a cutting plane. The loaf reload mechanism includes a loaf-staging position located over the loaf-loading position, the loaf-staging position having a lowering mechanism to position a loaf from the loaf-staging position to the loaf-loading position. The reload mechanism also includes a loaf-ready position located laterally adjacent to the loaf-staging position, and a sweep mechanism configured to laterally move a loaf from the loaf-ready position into the loaf-staging position.

Claims

1. In a slicing machine that includes a loaf-loading support wherein during a loading operation a loaf is placed in the loaf-loading support, a gripper that moves from a home position clear of a loaf on the loaf-loading support to an engagement position wherein the gripper engages a trailing end of the loaf, wherein during a slicing operation, the gripper moves with the loaf along a longitudinal path into a slicing plane of a moving slicing blade until the loaf is effectively entirely sliced by the blade, wherein the gripper is then retracted in a reverse direction to the home position, the improvement comprising:

a loaf-staging support extended along, parallel with, and in vertical alignment with, the loaf-loading support;

a lowering mechanism configured to deliver a loaf in a vertical direction from the loaf-staging support to the loaf-loading support;

a loaf-ready support laterally adjacent to the loaf-staging support; and

a sweep mechanism configured to laterally move a loaf from the loaf-ready support into the loaf-staging support; and

wherein said lowering mechanism is arranged to deliver the loaf in said vertical direction that is at an angle to the longitudinal path.

2. The improvement according to claim 1, wherein said loaf-staging support comprises a series of loaf supports that are sequentially removed by said lowering mechanism along the longitudinal path as the gripper is retracted, to sequentially undermine the loaf to drop the loaf progressively onto the loaf-loading support as the gripper is retracted.

3. A loaf slicing machine, comprising:

a blade that moves in a slicing plane to slice a loaf;

a first loaf support for guiding a loaf for longitudinal movement in a longitudinal direction along a loaf path to the slicing plane, said first loaf support extending to a position adjacent to said slicing plane and arranged to guide a leading end of the loaf into the slicing plane to be sliced by the blade;

a second loaf support that is above, extends along, and parallel with, said first loaf support such that a loaf on said second loaf support has a lead end at a first distance to said slicing plane and a loaf on said first loaf support before slicing commences has a lead end at a second distance to said slicing plane, wherein said first and second distances are substantially equal; and

a loaf-delivery means for progressively delivering the loaf from the second loaf support onto the first loaf support, wherein an end of the loaf that is closest to the slicing plane is delivered first from the second loaf support onto the first loaf support, and an opposite end of the loaf that is farthest from the slicing plane is delivered last from the second loaf support onto the first loaf support;

wherein said loaf-delivery means is arranged to deliver the loaf in a direction that is at an angle to the longitudinal direction.

4. The loaf-slicing machine according to claim 3, wherein said second loaf support comprises a plurality of support elements that are sequentially removed from under the loaf by said loaf-delivery means.

5. The loaf-slicing machine according to claim 4, wherein said support elements each comprise a support rod, and said loaf-delivery means comprises a plurality of pneumatic cylinders, each cylinder operatively associated with one support rod, and each said cylinder acts on said one rod using pneumatic force to either extend or retract said rod, each support rod supporting a portion of a loaf when in an extended position and releasing said portion of said loaf when said rod is retracted by said cylinder.

6. The loaf-slicing machine according to claim 4, comprising a third loaf support and a displacement mechanism, said displacement mechanism configured to move a loaf from said third loaf support onto said second loaf support, said third loaf support laterally adjacent to said second loaf support.

7. A loaf slicing machine, comprising:

a blade that moves in a slicing plane to slice a loaf;

a first loaf support having a support surface arranged to guide a loaf for longitudinal movement in a longitudinal direction along a loaf path to the slicing plane, said support surface extending to a position adjacent to said slicing plane and arranged to guide a leading end of the loaf into the slicing plane to be sliced by the blade;

a loaf engagement element that engages a trailing end of the loaf and moves from a home position for the slicing plane along the loaf path with the loaf being sliced and then retracts along the loaf path to the home position after the loaf is sliced;

a second loaf support that is above, extends along, and parallel with, said first loaf support, such that a loaf on said second loaf support has a lead end at a first distance to said slicing plane and a loaf on said first loaf support before slicing commences has a lead end at a second distance to said slicing plane, wherein said first and second distances are substantially equal, said second loaf support arranged for supporting a next loaf to be subsequently loaded onto said first loaf support; and

a loaf-delivery mechanism operatively connected to said second loaf support and operable to progressively displace the next loaf from the second loaf support onto the first loaf support, wherein a leading end of the next loaf that is closest to the slicing plane is displaced first from the second loaf support onto the first loaf support, and a trailing end of the next loaf that is farthest from the slicing plane is displaced last from the second loaf support onto the first loaf support;

wherein the leading end of the next loaf reaches the first loaf support before the engagement element has completely retracted to the home position; and

wherein said loaf-delivery mechanism is arranged to deliver the loaf in a direction that is at an angle to said longitudinal direction.

8. The loaf-slicing machine according to claim 7, wherein said second loaf support comprises a plurality of support elements that are sequentially removed from under the loaf by said loaf-delivery mechanism to progressively displace the next loaf from the second loaf support down onto the first loaf support.

9. The loaf-slicing machine according to claim 8, wherein said support elements each comprise a support rod, and said loaf-delivery mechanism comprises a plurality of pneumatic cylinders, each cylinder operatively associated with one support rod, and each said cylinder acts on said one rod using pneumatic force to either extend or retract said rod, each support rod supporting a portion of a loaf when in an extended position and releasing said portion of said loaf when said rod is retracted by said cylinder.

10. The loaf-slicing machine according to claim 8, comprising a third loaf support and a displacement mechanism, said displacement mechanism configured to move a loaf from said third loaf support onto said second loaf support, said third loaf support laterally adjacent to said second loaf support.

11. A loaf slicing machine, comprising:

a blade that moves in a slicing plane to slice a loaf;

a first loaf support means for guiding a loaf for longitudinal movement in a longitudinal direction along a loaf path to the slicing plane to guide a leading end of the loaf into the slicing plane to be sliced by the blade;
