Therefore, since a linkage mechanism is provided that links the opening and closing of the cover with the movement of the vacuum pad, an actuator or the like for opening and closing the cover is not required, and the configuration of the hand can be simplified. When the vacuum pad is in the capturing position, the cover automatically covers the circumference of the cutter, and the cover does not interfere with the vacuum pad's ability to capture fruits and vegetables to be harvested. In addition to preventing the cutter from getting caught on or damaging fruits and vegetables ready for harvesting or their branches and leaves, the cover also prevents the cutter from interfering with the operation of the cutter when the vacuum pad is positioned at the handle cutting position. It automatically becomes open.

b and rotates forward to project the push/pull member 30 forward, automatically opening the cover 28. Therefore, the cover 28 is automatically opened and closed in conjunction with the operation of the air cylinder 20 that constitutes the drive mechanism B that moves the vacuum pad 13 in and out. A linkage mechanism C that links the
has been configured. The cam surface 11b is formed so that the cover 28 is completely opened at the initial stage of the retraction operation when the vacuum pad 13 changes from the protruding state to the retracted state, and the vacuum pad 13 is at the handle cutting position. Immediately after starting the retraction operation, the cover 28 is opened, and when the fruit adsorbed by the vacuum pad 13 is brought into the handle cutting position, that is, the operating range of the cutter 21, the cover 28 will not catch the fruit, or the cover 28 will open. The opening/closing operation range of the cover 28 and the extension/retraction operation range of the vacuum pad 13 are shifted so that the fruit is not damaged by the cover 28.

In other words, the video camera So captures an image of the range in which the fruit F to be harvested is located, and performs image processing to remove the background such as branches and leaves to extract image information corresponding only to the target fruit. Calculate the direction in which the extracted fruit is located.

After the suction operation of the vacuum pad 13, the harvesting hand H is moved forward to the target fruit side by a set distance (for example, 30 to 50 mm), and the target fruit is suctioned based on the detection information of the negative pressure sensor S1 . If it is adsorbed as desired,
The air cylinder 20 for driving the vacuum pad in and out is operated to retract the vacuum pad 13, and the cover members 28a and 28b are opened outward, and at the same time, the harvesting hand H is moved along the direction in which the vacuum pad 13 moves in and out. The fruits to be harvested are brought into the operating range of the cutter 21 by moving forward. However, if the negative pressure sensor S1 does not operate, the vacuum pad 13 is projected, the cover 28 is closed, the suction operation is stopped, the harvesting operation is stopped, and the telescoping arm 9 is shortened. Then, return the harvesting hand H to the approach starting position.

After taking in the fruit to be harvested into the harvesting hand H, the cutter 21 and the stem support member are erected toward the front side, and based on the detection information of the erecting operation completion detection switch S3 , , determine whether the standing operation is completed.
When this rising operation is completed, the suction operation of the vacuum pad 13 is stopped, and
In this state, the harvesting hand H is moved back to position the cutter 21 on the base side of the fruit stem, and then
The cutter 21 is operated to cut the stem. Immediately after cutting, the suction operation of the vacuum pad 13 is started to suck the cut fruit again, and then the cutter 21 and the stem support member 22 are operated to fall until the retirement operation completion detection switch S4 is activated. Then, the telescopic arm 9 is shortened, the harvesting hand H is returned to the approach start position, the vacuum pad 13 is protruded, and its suction operation is stopped, and the harvested fruit is supplied to the conveyance device 4. , ends the harvesting operation for one fruit.
However, if the stand-up operation completion detection switch S3 does not operate and the stand-up operation is not completed, it is determined that a problem has occurred in which another object such as a branch has become caught.
The cutter 21 and the stem support member 22 are operated to fall down until the switch S4 for detecting the completion of the retirement operation is operated, and the telescopic arm 9 is shortened in the same manner as when the suction of the vacuum pad 13 is stopped, and the harvesting hand H
Return to the approach start position and stop the harvesting operation.

In addition, as mentioned above, when calculating the position direction of the fruit to be harvested, if a plurality of fruits are extracted based on one imaging information, for example, the fruits are harvested in order from the lower fruit to the upper side. Alternatively, the work may be continued in order, such as picking the largest fruit, that is, the fruit closest to the harvesting hand H.
