[0011]
As shown in FIG. 3, the support base 3 that supports the support shaft 5, the rotary blade 1, and the motor 4 is supported by a guide portion 35 of the base 6 so as to be movable up and down. The guide portion 35 has a guide shaft 36 erected, a coil spring 37 is inserted therein, and a linear bush 39 is attached to the guide shaft 36 so as to be movable up and down, supported by a U-shaped bracket 38. The U-shaped bracket 38 is connected to the back surface of the support base 3 so as to move the support base 3 up and down along the guide shaft 36.
[0012]
On the base 6, the lower part of the L-shaped operation lever 7 is connected by a pin 40, and the middle of the operation lever 7 is connected by the pin 40 to the lower part of the support base 3, and the operation lever 7 is lowered. When the support base 3 is lowered and the operation lever 7 is loosened, the coil spring 37 automatically raises and returns. Further, a protruding piece 42 is connected to the upper portion of the U-shaped bracket 38, and a limit switch 43 serving as an auxiliary start switch is attached in the vicinity of the protruding piece 42.
[0013]
As shown in FIG. 2, a start switch 45, a power switch 46, and a counter 47 are attached to the operation panel 9. The internal control circuit is configured as shown in FIG.

The contact b2 is a power switch provided between the power source and the motor 4, and is connected in parallel with the contact a2.
[0015]
The operation of the fruit peeling apparatus having the above configuration will be described. As shown in FIG. 3, the straw 30 is set in the cup-shaped fruit receiving portion 8. Next, when the operation lever 7 is lowered with the right hand, the support base 3 connected to the operation lever 7 with the pin 40 is lowered along the guide shaft 36. As the support 3 is lowered, the support presser shaft 5 is lowered together with the stopped peel-off rotary blade 1, and the support blade 3 is passed through the hollow 32 of the rotary blade 1 through the support 32 and the rotary cutter 1 and the support presser shaft. In the state where the supporter 26 of 5 is lightly in contact with the heel 30, the start switch 45 of the operation panel 9 is pushed and released with the finger of the left hand.
[0016]
Further, as the support base 3 is lowered, the protruding piece 42 attached to the U-shaped bracket 38 moves away from the limit switch 43 serving as a start auxiliary switch, and the contact 43A is turned on as shown in FIG. When the start switch 45 of the panel 9 is turned on, the relay A series circuit shown in FIG. 7 is turned on, and the contacts a1, a2, and a3 are turned on. When the contact a1 is turned on, the relay A is in a self-holding state. Further, the contact a2 serving as a power switch is turned on, and the motor 4 is energized from the power source, so that the motor 4 starts rotating.
[0017]
Further, when the contact a3 is turned on, this becomes a start switch, the series circuit of the relay B becomes conductive, and the contacts b1 and b2 are turned on. When the contact b1 is turned on, the relay B is in a self-holding state. The contact b2 is also turned on, but the motor 4 remains rotated because the contact a2 is already turned on.
[0018]
When the motor 4 rotates in this way, the pulley 19B rotates as shown in FIG. 3, and the pulley 19A also rotates via the belt 20. Since the blade attachment portion 2 is connected to the pulley 19A via the rotary shaft 18, the rotary blade 1 attached here rotates.
[0019]
At this time, the bottom surface of the C-shaped blade body 11 of the rotary blade 1 rotates while pressing the side 31 of the flange 30 and peels off the cracks and the skin 33 around the side 31 with the cutting blade 13 as shown in FIG. . The peeled peel 33 rises from between the slits 12 to the back side. Since a plurality of skin removing plates 15 are attached to the back surface of the blade body 11 so as to rise in the direction opposite to the rotational direction, the peeled skin 33 is obliquely upward. It can be prevented from being blown away and clogging the mounting portion of the rotary blade 1.
[0020]
The rotary blade 1 rotates at about 3 rotations per second and peels off the skin 33 around the spatula 31. In the circuit shown in FIG. 7, if the timer 51 is set to 2 seconds, for example, an OFF signal is output to the OFF switch 50 after 2 seconds from the start of rotation of the motor 4, and the relay A is held off. Canceled. When relay A is released, all of its contacts a1, a2, a3 are also turned off. Even if the contact a2 is turned off, the circuit of the relay B is self-held, so the contact b2 remains on and the motor 4 continues to rotate.
[0021]
After this, as shown in FIG. 5, when the limit switch 23 comes into contact with the protrusion 22 provided on the pulley 19A, the contact 23B serving as a turn-off switch is turned off, and the holding of the circuit of the relay B is released. As a result, the contacts b1 and b2 are turned off, the power is cut off, and the motor 4 is stopped. Also, until the limit switch 23 is actuated and the motor 4 is stopped, the motor 4 is rotated in the reverse direction, for example, as shown in FIG. 6, with the slit 12 side provided with the cutting blade 13 positioned on the back side of the support foot 26 Can be made.
[0022]
That is, since the tip of the cutting blade 13 protrudes from the hollow portion 14, when this comes to the near side of the support 32, when the operation lever 7 is raised and the rotary blade 1 is raised, the operation lever 7 is lowered. Sometimes the branch 32 is caught and broken. For this reason, in the present invention, when the rotary blade 1 is moved up and down by stopping the cutting blade 13 in a state where it is positioned on the back side of the support presser 26, the support 32 can easily pass through the hollow portion 14, Damage to the support 32 connecting the strings can be prevented.
[0023]
During the 2 seconds during which the timer 51 is operating, the limit switch 23 comes into contact with the protrusion 22 of the pulley 19A, and the contact 23B is turned off several times. Each time the circuit of the relay B is released, the contact is made. b1 and b2 are turned off. However, since the contact a2 is held in the ON state, the motor 4 continues to rotate, and the contact a3 is also held in the ON state, so that the relay B returns to the self-holding state again. Therefore, since the timing of the release is determined by the mounting position of the protrusion 22 of the pulley 19A until the relay B is released after the relay A is released, the rotary blade 1 can be stopped at the same position.
[0024]
In the above description, the blade main body 11 is formed in a C shape. However, as shown in FIG. 8, the blade main body 11 may be formed in a keyhole shape in which a radial slit 12 is provided in the hollow portion 14. Further, by providing an air ejection nozzle in the vicinity of the rotary blade 1, the skin can be further efficiently discharged and discharged. In the above description, the case where the skin 33 of the straw 30 is peeled is shown, but the present invention can be applied to other fruits. Moreover, although the said apparatus was shown about the vertical structure, a horizontal structure may be sufficient.
[0025]
【The invention's effect】
As described above, according to the fruit peeling apparatus according to claim 1, since the rotary blade does not rotate unless the operation lever and the start switch are operated at the same time after setting the straw in the fruit receiving portion, It is extremely safe compared to conventional devices that hold and press against a rotating blade. In addition, the rotary blade has the cutting edge projecting into the hollow part of the ring-shaped blade body and a skin removal plate protruding from the back of the blade body. The fruit can be peeled smoothly and smoothly continuously.
[0026]
Further, according to the fruit peeling apparatus according to claim 2, since the rotary blade can be stopped at a predetermined position, the rotary blade is moved by operating the operation lever to contact the cocoon, When the stripping is finished and released, the branch passes smoothly through the hollow portion, so that damage to the branch can be prevented.
