In this type of robot hand, it is necessary to provide a cutter with a blade member for cutting the tenon of the fruit after capturing the fruit, but the structure of the drive mechanism of the blade member and its arrangement position etc. When designing the hand, there were various requirements such as not increasing the size or weight of the hand as a whole, and being able to cut the tenon of the fruit reliably and well, so the design was extremely difficult. Have difficulty.

本発明の目的は、このような要求を満たすことのできる

In order to achieve the above object, the cutter according to the present invention has a pair of blades in which a blade part is formed on the inner circumferential side of a semicircular or semicircular member and a gear part is provided on one end side of the member. The member is slid by one rack and pinion that engages with each of the gear parts at the same time between a substantially circular arrangement state in which the respective blade parts face each other and a cross state in which the respective outer peripheral parts face each other. It has the feature that it is structured as follows.

Due to this characteristic configuration, the following effects are exhibited. In other words, when driving the two blade members so as to cross each other, one gear is provided at each end of the blade member, and one rack and pinion is provided that engages these two gears at the same time. A simple configuration was adopted. By doing so, it is possible to make the cutter itself, and even the entire device equipped with the cutter, such as a robot hand for fruit harvesting, more compact and lightweight. In order to drive them simultaneously by rack and pinion, the timing and synchronization of their w1 movements are adjusted. Although there is no need for any special cutter mechanism, the two semicircular blade members can be made to intersect accurately at the center of the circle. Therefore, this cutter can be applied to a robot hand for fruit harvesting equipment. In addition, in this case, no matter where the fruit is introduced into the hand, the tenon is pulled to the approximate center of the catching part by the two blade members. It can be cut really well.

以下、本発明の実施例を図面に基いて説明する。Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 1, the fruit harvesting device has a movable main body (
(not shown) is attached with a bendable arm (2),
A fruit-catching hand (3) is attached to the tip of the fruit-catching hand (3) via a joint (1) so as to be able to freely change direction. In this fruit catching handle (3), one I-14 outlet of the hollow cylindrical catching part (4) is formed in the fruit introduction port (5), and one fruit is stored in the opening of the fruit inlet (5). A chute (6) for conveying the fruit to a storage section (not shown) is connected to the chute (6).The hand (3) has a fruit introduction port (5) of the hand (3) through which the hand F (3) introduces the fruit. A contact sensor (131...) is provided to control the fruit so that it enters the mouth (5), and a cutter (7) is provided to cut the tenon of the fruit introduced into the trap (4). . This cutter (7) has a capture a (4)
The device operates when a sensor (not shown) provided inside the trap detects that the fruit has been correctly introduced into the trap, and cuts the tenon of the fruit.
