DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention comprises a cutter for cutting a captured fruit and vegetable handle, and a handle supporting member for supporting the fruit and vegetable handle. The handle support member is configured to be switchable between a state in which it is projected to support the handle of the fruit and vegetables between them and a state in which it is retracted to form a passage for introducing the fruit and vegetables between them. In order to automatically change the protruding positions of the cutter and the handle support member in accordance with the positions of the handles of the fruits and vegetables that have captured the actuators, the cutter and the handle support member are respectively operated to move in and out of the cutter and the handle support member. The present invention relates to a handle cutting device in a fruit and vegetable harvesting hand, which is interlockingly connected to the handle via a differential mechanism.

The operation of the differential mechanism (21) will be described. The output gear (42) is rotationally driven by the electric motor (19) via the input gear (41), and accordingly, the output gear (42) is rotated. (42) planetarily rotates along the circumference centered on the fixed shaft core (P) to move the position of the horizontal shaft core (Q) to
The handle supporting member (18) is pivotally supported, that is, the horizontal axis (Q), while changing the position rearward toward the lower side of the hand.
The handle support member (18) is rocked around the upper hand so that the handle supporting member (18) is rocked toward the upper hand so as to draw an elliptical orbit.

Further, since the output gear (42) is pivotally supported by the pivot member (17c) extending to the end of the cutter (17), the output gear (42) with respect to the input gear (41). As the planet rotates, the pivot member (17c) moves downward around the fixed shaft core (P), so that the cutter (17) moves the handle support member (18). At the same time as swinging upward, it is swung downward.

However, when the cutter (17) comes into contact with the fruit handle first, it is prevented from rotating around the fixed shaft core (P).
Although the swing of the cutter (17) is stopped, the output gear (42) is driven through the input gear (41), so that the handle support member (18) causes the cutter (17) to move. 17)
The swing operation is continued around the horizontal axis (Q) at the position where the swing is stopped.

On the other hand, when the handle support member (18) comes into contact with the handle of the fruit first, the handle support member ((7) that comes into contact with the handle as the planetary rotation of the output gear (42) with respect to the input gear (41) rotates. The tip end of 18) serves as a fulcrum, and the end side of the handle support member (18) is swung toward the rear side of the hand along a circumference around the fixed shaft core (P) and at the same time, The pivot member (17c) on the cutter (17) side is swung toward the rear side of the hand along the circumference centered on the fixed shaft core (P), and as a result, the handle support member (18). The cutter (17) is continuously swung downward while maintaining the state in which the upward swing of the cutter is stopped.

However, at the time of the cutting operation of the movable blade body (17b), an operation force toward the retreat side is applied to the cutter (17) by the pinion (30), but the differential mechanism (21)
Is composed of an input gear (41) rotatably driven around the fixed shaft core (P) and an output gear (42) having the same gear ratio and planet-rotating with respect to the input gear (41), and Since the input gear (41) is linked to the electric motor (19) via the worm gear (36), the input gear (41) is locked when the electric motor (19) is stopped. Becomes Therefore, if the cutting resistance is large due to the handle being thick or hard, the movable blade body (17b) slides as the pinion (30) is rotationally driven for cutting the handle. Instead, the pinion (30) generates an operating force that swings the fixed blade body (17a) and the movable blade body (17b) to the retracted side, but the output gear (42) is Since the input blade (41) is provided so as to rotate in a planetary manner, the handle supporting member is moved by a movement amount that is twice the movement amount of the fixed blade body (17a) as it is moved to the retracted side. The cutter (17) acts so as to swing toward the protruding side, and the cutter (17) is brought into contact with the handle support member (18) or the handle is sandwiched between them to allow the cutter (17) to move. The swinging of the handle and the handle support member (18) is prevented.

Completion of the standing operation in which the cutter (17) and the handle support member (18) support the handle of the fruit between them is completed by changing the swing positions of the cutter (17) and the handle support member (18). It is detected by a potentiometer (S4) as a protrusion amount detecting means for detecting the sum of those protrusion amounts. The potentiometer (S4) directly detects the swing position of the handle support member (18), but the cutter (17) and the handle support member (18) use a differential mechanism (21). Since they are interlocked with each other, the swing position of the cutter (17) can be detected by detecting the swing position of the handle support member (18) that supports the handle.
