[Problems to be Solved by the Invention] However, in the conventional slicer, since the cutting is performed only by pressing an object to be sliced such as bread against the blade, a large amount of bread residue of the sliced bread is generated. There is. As a result, when the cutting is repeatedly performed, the pan residue is accumulated, so that the number of times of cleaning increases and it is not preferable in hygiene.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and it is easy to cut sharply in order to prevent the generation of scraps of the sliced object, and efficient and smooth cutting can be performed. An object is to provide an ultrasonic slicer that achieves compactness.

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the ultrasonic slicer of the present invention.

In the figure, reference numeral 1 is a round blade as a circular blade body having a waved blade 1b having a wavy blade formed on the entire circumference as shown in FIG. It is desirable that the wave edge 1b should vibrate at the edge of about 10 to 200 μmp-p. Also, the resonance frequency is 10KHz to 100KH
Although about z can be considered, 10 KHz to 60 KHz is particularly desirable. The center of the round blade 1 is screwed onto the horn 2 at right angles to the vibration direction 2a of ultrasonic vibration. Therefore, the round blade 1 can be easily replaced with the corrugated blade 1b having the above amplitude. The horn 2 is connected to the vibrator 3 on the surface opposite to the surface connected to the round blade 1, and the vibrator 3 is excited by the oscillator 8 to generate ultrasonic vibration. The inner rotating case 7a in which the vibrator 3 is incorporated is rotatably supported by the case 7 via a bearing 7b, and is connected to the motor 6 via a conductive portion 5. Between the vibrator 3 and the conducting portion 5, brushes 4a and 4b are in sliding contact with ring-shaped electrodes 4c and 4d connected to the electrode 3a of the vibrator 3. This brush 4a
And 4b are supplied with the excitation power from the oscillator 8, and the oscillator 3
Is always supplied to. The motor 6 is driven by a power source (not shown) to rotate the inner rotating case 7a. Since the inner rotating case 7a and the horn 2 are connected via the flange portion 2b and the packing 2c,
The rotation of the inner rotating case 7a causes the horn 2 and the round blade 1 to rotate.
Rotates. At this time, the ultrasonic vibration generated by exciting the vibrator 3 has its vibration amplitude expanded by the horn 2 and is transmitted to the center of rotation of the round blade 1. The vibrating direction 2a of this ultrasonic vibration coincides with the rotation axis direction of the round blade 1, and the diameter of this round blade 1 is
Since the resonance length of the flexural vibration in the radial direction of the round blade 1 based on the vibration transmitted from the horn 2 is determined, the round blade 1
Performs flexural vibration in which a flexure curve 1c is drawn on the diameter, for example. Therefore, the sliced object is pressed against the rotating circular blade 1 and cut into the corrugated blade 1b, and the circular blade 1 vibrates in the rotation axis direction thereof, that is, in the direction in which the circular blade 1 separates the sliced object cut surface. As a result, sharpness is sharpened, and the amount of generation of pan residue can be reduced. In the present embodiment, the inner rotating case 7a and the horn 2 are connected to each other via the flange portion 2b and the packing 2c, but the flange portion 2b may be used alone.

The operation of this embodiment having the above configuration will be described.

First, as shown in FIG. 1, the inner rotating case 7a is rotated by the motor 6 which is a rotary drive source. The inner rotating case 7a, the horn 2 and the vibrator 3 rotate to rotate the round blade 1 having the wave blade 1b formed thereon. At the same time, the excitation power from the oscillator 8 is applied to the vibrator 3 to generate ultrasonic vibration. As a result, the circular blade 1 is vibrated about its rotation center in the rotation axis direction 2a. Since the diameter of the circular blade 1 is set to the resonance length of the flexural vibration, the flexural vibration is defined by the flexural curve 1c. As a result, in the round blade 1, antinodes of the standing wave are concentrically formed in several places including the portion of the wave blade 1b and vibrate. Therefore, the sliced object is pressed against the rotating circular blade 1 to be cut, and the circular blade 1 vibrates in the direction separating the cutting surfaces to sharpen the sharpness and suppress the generation of cutting scraps to a small amount. You can

According to the experimental example using the ultrasonic slicer according to the present embodiment, as a result of measuring the amount of chips (bread crumbs) generated by cutting the roll bread by applying ultrasonic vibration to the round blade having the wave blade formed, As a result of comparing the case of applying sonic vibration and the case of not applying sonic vibration,
It decreased to less than 40%.

[Measurement method] A slicer having a diameter of 210 mm, a thickness of 1.5 mm, a taper width of 15 mm, a material SKS2 and a corrugated blade was used.

Conditions: Ultrasonic vibration: Wave edge amplitude 20μmp-p Conveyor feed speed: 18m / min Blade rotation speed: 120rpm Resonant frequency of vibration system: 19.5KHz [Measurement result] (Comparison of bread crumb weight with or without ultrasonic vibration) By the way, as is apparent from the drawing, in the above ultrasonic slicer, the case is double inside and outside like the case 7 and the inner rotating case 7a, and the transducer 3 is further installed inside the inner rotating case 7a. . That is, the entire device is concentrically provided with a multiple structure, and the device is made compact by adopting such a configuration.

On the other hand, the horn 2 is formed with a flange portion 2b extending perpendicularly to the rotation axis direction, and the flange portion 2b is attached to the inner rotation case 7a. This flange 2b is usually
Since the horn 2 is formed at the vibration node position, the vibration system can effectively vibrate by mounting with the flange portion 2b. Therefore, damping of vibration is suppressed and cutting efficiency is improved. improves.

Further, in the ultrasonic slicer, the motor 6 serving as a rotational drive source supplies the ring-shaped electrode 4 for feeding power to the vibrator 3.
It is connected to the inner rotating case 7a via c and 4d. In other words, the vibrator 3, the ring-shaped electrodes 4c and 4d, and the motor 6 are arranged in a straight line in a row and without a reduction mechanism or the like interposed therebetween, which also contributes to downsizing of the entire apparatus. Has been planned.

Further, the corrugated blade of the round blade 1 has a symmetrical shape in the rotation direction with respect to the one wave. As a result, an orderly vibration mode can be obtained and smooth cutting can be performed, and cutting can be performed by rotation in both forward and reverse directions.

[Effects of the Invention] As described above, according to the present invention, the circular blade body having the rotating wave blade is excited in the rotation axis direction at the center of rotation, so that sharpness is sharpened. In addition, there is an effect that the amount of waste such as bread that is the sliced object is reduced.

Further, since the case of the device has a double structure of the inside and the outside and the vibrator is housed in the inside rotation case, the device can be made compact.

Further, since the horn is attached by the flange portion formed at the vibration node, vibration damping is suppressed and cutting efficiency is improved.

In addition, since the vibrator, the ring-shaped electrode, and the rotary drive source are linearly arranged in a line, the device can be made compact.

Further, since the corrugated blade of the circular blade body has a symmetrical shape in the rotational direction with respect to one wave thereof, an orderly vibration mode can be obtained and smooth cutting can be performed.
