Abstract

A food slicer includes a feeder for feeding a lump of food in one direction, an end detector for detecting an end portion of the lump of food fed by the feeder, a cutter for cutting the lump of food from its leading end into slices, and slice receivers arranged for advancing to and retracting from a dropping path of the slices released from the cutter. A controller is responsive to a detection signal of the end detector for controlling the advancing and retracting movements of the slice receivers.

Claims

1. A food slicer comprising:

a feeding means for feeding a lump of food in one direction;

an end detecting means for detecting an end portion of the lump of food fed by said feeding means;

a cutting means for cutting the lump of food from a leading end thereof into slices;

first and second slice receivers driven independently by first and second drives, respectively, for movements advancing to and retracting from a dropping path of slices released from the lump of food by said cutting means; and

controller means, operably connected to said first and second drives and responsive to a detection signal from said end detecting means, for controlling said advancing and retracting movements of said first and second slice receivers and for ensuring that both said first and second slice receivers are retracted from said dropping path when slices of non-standard sizes representative of cutting of the end portion of the lump of food are delivered by said cutting means.

2. A food slicer according to claim 1, wherein said controller means is operable to move a respective said slice receiver to advance across said dropping path for receiving a stack of slices when slices of a standard size are delivered by said cutting means, and to retract from said dropping path when the slices of non-standard sizes are delivered.

3. A food slicer according to claim 2, further comprising a conveyor device mounted beneath a receiving position of said slice receivers across said dropping path for receiving a stack of slices dropped from above and conveying the stack outwardly of said dropping path, and wherein said controller means is operable to move a respective said slice receiver to and from said dropping path at a sufficiently low speed to maintain the stack of slices on said respective slice receiver when the number of the slices of the stack is smaller than a predetermined number, and to retract said respective slice receiver from said dropping path at a sufficiently high speed to prevent the stack of the slices from moving with said respective slice receiver and to drop by static inertia onto said conveyor device when the stack includes the predetermined number of the slices.

4. A food slicer according to claim 3, further comprising means for moving said slice receivers upwardly and downwardly, and said controller means is operable to lower a respective said slice receiver by a distance substantially equal to the thickness of a slice received on said respective slice receiver and when the predetermined number of slices have been received on said respective slice receiver, to further lower said respective slice receiver to a level just above and adjacent to an upper surface of said conveyor device, and then to retract said respective slice receiver from said dropping path.

5. A food slicer according to claim 4, wherein said conveyor device comprises a discharging means for discharging the slices of non-standard sizes.

6. A food slicer according to claim 3, wherein said conveyor device comprises a discharging means for discharging the slices of non-standard sizes.
