DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food slicer for diagonally cutting an object to be cut, which is an elongated food material such as burdock or green onion.

[0002]

2. Description of the Related Art As a conventional food slicer for performing oblique cutting, an elongated cut object such as burdock or green onion, which is manually or automatically fed by an appropriate amount along a guide portion provided to be inclined with respect to a horizontal plane. Is cut from the back side of the object to be cut by a nagi blade fixed to a rotating shaft, and is known.

[0003]

In a conventional food slicer, the sharp-cutting end of the object to be cut may be cut into a proper shape so that there is an escape in which the object is pushed back by the knife and then slightly retreated. Have difficulty. The phenomenon of escape is almost eliminated by adopting a structure in which the vicinity of the cut end of the cut object is supported by the base member. However, the cutting angle cannot be freely changed, or the cut object cannot be cut. There are inconveniences such as an extremely complicated automatic feed mechanism. Therefore, the present inventor studied such a problem, and invented the present invention based on the idea of a smooth cutting operation in which a cook cuts an object to be cut on a cutting board obliquely using a kitchen knife. It was completed.

An object of the present invention is to provide a food slicer which can cut a cut object, which is a food material, diagonally and smoothly, and can cut the cut object into a proper shape. Is to do.

[0005]

In order to achieve the above object, according to the present invention, a triangular arrangement is provided between the axes of the crankshafts so that the crankshafts can be freely rotated in the horizontal direction on the frame. In addition to supporting and rotating one of the crankshafts by a motor driving device, a moving plate is vertically attached to a crankpin protruding from a crank arm of each crankshaft. A blade mounting member on which the blade is mounted with its cutting edge horizontal is provided so as to be finely movable in the vertical direction, and the blade mounting member is always urged downward by a spring, so that the object to be cut has a spring elasticity. A pressing member is provided so as to approach the side of the blade, and a conveying direction of a conveyor device for intermittently feeding the object to be cut in a horizontal direction with respect to a longitudinal direction of the blade is a predetermined angle when viewed from a plane. The parallel movement having a trajectory for linearly moving the cutting edge resiliently contacting the conveying surface of the conveyor device in one direction by driving and rotating the crankshaft by the motor driving device is arranged. An object to be cut, which is applied to the blade and is intermittently stopped by being sent by the conveyor device, is pressed by a pressing member and cut obliquely by the blade.

According to a second aspect of the present invention, there is provided a food slicer according to the first aspect, wherein an intersection angle formed by a longitudinal direction of the blade and a conveying direction of a conveyor device is fixed. It is characterized in that it is provided so as to be adjustable arbitrarily within an angle range.

It is preferable that the cutting tool in the food slicer according to the first or second aspect of the present invention is provided with a through hole for preventing the cut piece from adhering to the cutting edge.

[0008]

When the crankshaft is driven and rotated by the motor driving device, the cutting edge resiliently contacted with the blade on the conveying surface of the conveyor device linearly moves in one direction (rearward), and then once. A parallel motion having a series of trajectories of ascending and linearly moving in the opposite direction (forward), and then descending and returning to the original linear movement is given. Thus, the cut object that is sent by the conveyor device and intermittently stopped is cut diagonally by the blade while being pressed by the pressing member. Then
A series of operations in which the object to be cut is fed by an appropriate amount when the blade is raised, and the object to be cut or pushed is cut by the blade to which the cutting or pushing operation is performed in a state where the object is pressed again by the pressing member. Is repeatedly performed.

The degree of oblique cutting of the object to be cut can be changed by adjusting the crossing angle of the object with the blade of the conveyor device.

Since a through hole is appropriately provided in the cutting edge portion of the cutting tool, the phenomenon that the cut piece adheres to the cutting edge portion as it is and does not separate is almost eliminated.

According to this food slicer, the object to be cut, such as burdock or green onion, can be cut smoothly and diagonally by the operation of being cut off with a kitchen knife. And the section is
There is an advantage that the cut end portion is processed into a beautifully formed acute angle shape, and the added value as a cooking material is enhanced.
