The slit 4 is a hole through which the blade portion 11 of the cutting blade 10 passes with a sufficient margin in the position where the cutting blade 10 cuts the workpiece 30. The slit 4 is elongated in the direction along the rotation surface of the cutting blade 10.
[0016]
The cutting blade 10 is provided with a blade portion 11 on the side in the longitudinal direction which is the lower side during cutting, the rotation shaft 5a passes through the vicinity of the lower end portion in the reference stationary state, and the other end portion. The driven portion 12 is provided in the main body.
The turning-side plate 20 is a plate-like shape in which each side of the triangle is greatly curved, and the curved portion 21 on the side in contact with the object to be cut is a half-moon shape that is recessed toward the center. The curved portion 21 is covered with a cushion material made of a flexible material such as rubber or synthetic resin, or a cushion material is attached so as to protrude.
[0017]

[0020]
The operation of the first embodiment will be described below.
FIG. 4 is an explanatory diagram (front view) showing the progress of the root vegetable cutting operation of the embodiment shown in FIGS. 1 to 3.
FIG. 5 is an explanatory view (front view) showing a state when the cutting of root vegetables in the embodiment of FIG. 4 is completed.
[0021]
When cutting the root vegetables according to the first embodiment of the present invention, the operator first shows the object (root vegetables) 30 to be cut at an appropriate position on the upper surface of the base 2 of the base as shown in FIG. Put it like this.
Next, when a foot switch (not shown) is pressed, compressed air is sent from a compressor (not shown) to the first cylinder 23 under the control of a controller (not shown), and the movable part 23a of the first cylinder 23 is moved to FIG. As shown in FIG. Therefore, the turning side plate 20 rotates around the rotation shaft 5 a and presses the root of the object 30 at the position indicated by the two-dot chain line with the curved portion 21.
[0022]
At this time, since the cutting blade 10 also rotates together with the turning side plate 20, the blade portion 11 does not come out of the curved portion 21 of the turning side plate 20. Further, the tip of the turning side plate 20 is guided by the groove 3a having a V-shaped cross section of the guide block 3 and pushes the root of the object 30 at a precise position without swinging left and right. Since the portion 21 is made of a flexible material such as rubber, it does not damage the leaves.
[0023]
Subsequently, compressed air is sent from a compressor (not shown) to the second cylinder 25 under the control of a control unit (not shown), and the movable part 25a of the second cylinder 25 extends as shown in FIG. Therefore, the cutting blade 10 rotates relative to the turning side plate 20 around the rotation shaft 5a, and cuts and cuts off the root of the object 30 at the position indicated by the two-dot chain line with the blade portion 11. .
[0024]
Since the object to be cut 30 is held with both hands, the cutting position can be easily and reliably adjusted, and the cutting blade 10 rotates along the revolving side plate 20 so that the leaf can be cut off at the target position with certainty. it can.
Separately from this embodiment, a bundling machine (not shown) is prepared, and simultaneously with this cutting, a signal is sent from a control unit (not shown), and the portion of the cut leaf is taped in synchronization with the cutting operation of the apparatus. Also good.
[0025]
Subsequently, under the control of a control unit (not shown), compressed air is sent to the second cylinder 25 from a compressor (not shown), and the movable unit 25a of the second cylinder 25 is contracted as shown in FIG. Therefore, the cutting blade 10 rotates relative to the turning side plate 20 around the turning shaft 5a, and returns to the original position shown in FIG. 4 (a position hidden along the turning side plate 20).
[0026]
Subsequently, under the control of a control unit (not shown), compressed air is sent to the first cylinder 23 from a compressor (not shown), and the movable part 23a of the first cylinder 23 is contracted as shown in FIG. Accordingly, the turning side plate 20 rotates about the rotation shaft 5a, the curved portion 21 rises, and returns to the state before the foot switch is pressed.
Then, it waits for the foot switch to be pressed.
[0027]
(Second Embodiment)
FIG. 6 is a front view of the second embodiment of the present invention.
FIG. 7 is a plan view of the embodiment of FIG.
The second embodiment is different from the first embodiment in that the first embodiment requires a separate foot switch for starting a series of operations, whereas the second embodiment includes a pedestal 2 in the apparatus itself. A detection mechanism that detects that the workpiece is placed at the upper fixed position and sends a signal to a control unit (not shown), and a workpiece to guide the workpiece to a position where the detection mechanism is located. A guide is provided, and a series of operations are activated by a signal sent out by the detection mechanism.
[0028]
That is, in the second embodiment, as shown in FIGS. 6 and 7, the sensor 7 as the detection mechanism and the elongated guide plate 8 as the workpiece guide are vertically arranged on the base 2 on the upper surface of the base 2. These are the same as those in the first embodiment shown in FIGS.
When placing the workpiece 30 on the upper surface of the pedestal 2, firstly lightly touch the workpiece 30 to the guide plate 8 and move it down as it is, or after placing it on the upper surface of the pedestal 2 near the guide block 3 and then guide plate 8. It may be moved until it touches.
[0029]
The position of the guide plate 8 on the pedestal 2 continuously cuts the same kind of root vegetables so that any object to be cut just touches the sensor 7 even if the size and shape of the object to be cut 30 have some variation. The adjustment screw 8a may be adjusted in advance.
In the subsequent operation, the sensor 7 automatically works instead of the foot switch of the first embodiment, and operates in the same manner as in the first embodiment.
The sensor 7 uses a highly durable touch sensor having a dustproof and waterproof function as much as possible. In the present embodiment, the movable part of the microswitch is covered with a rubber film and arranged so as to slightly protrude from the upper surface of the base 2.

For example, the shape of the turning side plate 20 is not limited to that shown in FIGS. When the revolving side plate 20 and the cutting blade 10 are in the reference stationary position, any shape can be used as long as the cutting blade 10 is not visible behind the revolving side plate 20 when viewed from the revolving side plate 20 side of the apparatus.
[0031]
The air cylinders 23 and 25 are used for the first drive mechanism and the second drive mechanism that drive the turning side plate 20 and the cutting blade 10, but an electric actuator such as a motor may be used.
The base, guide block, blade / side plate support, first and second cylinder support, workpiece guide, each fitting, etc. are all shown in FIGS. Even if they are different, there is no problem as long as they are within the gist of the present invention.
[0032]
Also in the second embodiment, in addition to the above, the sensor 7 uses a microswitch in this embodiment, but may be another touch sensor or a non-contact proximity sensor. Further, in FIG. 6 to FIG. 7, the sensor 7 is disposed on the upper surface of the pedestal 2, but may be attached to the other surface of the pedestal 2, the guide plate 8, the guide block 3, or the like. In short, it is only necessary to detect that the object to be cut is in an appropriate position at the time of cutting.
