MODE FOR INVENTION

[0036] Hereinbelow, the configuration and operation of an ultrasonic bread cutter according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0037] FIG. 1 is a block diagram of the ultrasonic bread cutter according to the embodiment of the present disclosure, FIG. 2 is a front view of the ultrasonic bread cutter according to the embodiment of the present disclosure, FIG. 3 is a side view of FIG. 2, and FIG. 4 is a top plan view of FIG. 2.

[0038] In the ultrasonic bread cutter 100 according to the embodiment of the present disclosure, the electrical energy having ultrasound (high frequency) is converted into mechanical energy of vertical movement by an ultrasonic unit 130; the mechanical vibration which is the mechanical energy is transmitted to a cutting knife 140, and the cutting knife cuts through bread by using the mechanical vibration.

[0039] Ultrasound is a type of a sound wave and normally has excessive frequency of 20 KHz or more, and thus cannot be discerned by human hearing.

[0040] Ultrasound has essentially the same properties as a sound wave in an audible range, but has properties in contrast to the properties of normal audible sound wave, such as excessive vibration occurring due to a short wavelength, so ultrasound has various applications.

[0041] For example, ultrasound is applied to a sonar (sound navigation and ranging) measuring the depth of water, and to an ultrasonic flaw detector which detects damage within a structure by measuring difference in rate of the ultrasound absorbed by the structure or in propagation speed of the ultrasound in the structure.

[0042] An ultrasonic oscillator 120 is a device converting the electrical energy having the frequency of 50˜60 Hz into high-powered energy having high frequency (15˜30 KHz) and supplying the high-powered energy having high frequency to a vibrator of the ultrasonic unit.

[0043] When an OP panel 160 is manipulated, a control unit 110 adjusts the cutting condition of an ultrasonic wave and controls the oscillation time and motion of the ultrasonic wave, and the operation of X-axis, Y-axis, Z-axis transfer motors 152, 154, and 156 and of a rotating motor 158.

[0044] The vibrator 132 of the ultrasonic unit 130 converts ultrasonic electrical energy having the high frequency supplied by the ultrasonic oscillator 120 into the mechanical energy of vertical vibration.

[0045] A horn 134 of the ultrasonic unit 130 is configured to obtain amplitude required by the cutting knife 140 when the bread is cut.

[0046] The cutting knife 140 transmits the mechanical energy (vibration) generated by the vibrator 132 to the bread so as to cut the bread.

[0047] In this case, in consideration of the height of the bread, the cutting knife 140 preferably has length of 30˜60 mm, and is coupled to the rotating motor 158, and can cut the bread while rotating in direction of the blade of the cutting knife when cutting the bread.

[0048] The ultrasonic unit 130 and the cutting knife 140 can move in X-axis (left and right), Y-axis (forward and backward), and Z-axis (vertically) directions. That is, the ultrasonic unit 130 and the cutting knife 140 can be moved in each of the directions by the X-axis transfer motor 152, the Y-axis transfer motor 154, and the Z-axis transfer motor 156 operated by the control of the control unit 110.

[0049] More specifically, an X-axis unit 151 is installed at a side (at a right side in FIG. 2) of a base 102 on which bread is laid such that the X-axis unit 151 moves left and right, and is left and right moved by the X-axis transfer motor 152.

[0050] An XY-axis unit 153 is installed at the X-axis unit 151 and at an inner side of the base 102 such that the XY-axis unit 153 moves forward and backward, and is moved forward and backward by the Y-axis transfer motor 154. Accordingly, the XY-axis unit 153 can move left and right and forward and backward.

[0051] An XYZ-axis unit 155 is installed at the XY-axis unit 153 and at an inner side of the base 102 such that the XYZ-axis unit 155 moves vertically, and is vertically moved by the Z-axis transfer motor 156. Accordingly, the XYZ-axis unit 155 can move left and right, forward and backward, and vertically.

[0052] That is, the ultrasonic unit 130 and the cutting knife 140 are mounted to the XYZ-axis unit 155, and can move in the X-axis (left and right), Y-axis (forward and backward), and Z-axis (vertically) directions.

[0053] The cutting knife 140 cuts through the bread on the base 102 by the mechanical vibration with the bread dry by moving vertically while moving left and right or forward and backward.

[0054] In this case, the cutting knife 140 is connected to the rotating motor 158 and can cut the bread while rotating in the direction of the blade of the cutting knife 140.

[0055] In addition, the distance of the vertical movement of the cutting knife 140 may be adjusted to be 10˜100 mm, and as the distance of the vertical movement increases, frequency is constant and the speed of the vertical movement increases, so bread can be cut to have a smooth surface.
