Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves setting bags of fruit collected from fruit trees on a fruit receiving seat provided on a conveyor, conveying the fruit, and cutting the fruit using a paper bag cutting device provided on the underside of the conveyor. The opening of the paper bag that covers the outer surface of the fruit protruding from the fruit receiving seat to the lower surface of the conveyor is cut off, and then the paper bag is blown away from the lower surface of the conveyor by pressure air or suction installed on the upper surface of the conveyor. The present invention relates to an improvement in a paper bag cutting device disposed on the lower surface side of the conveyor in a fruit bag removing device in which the fruit is removed from the outer surface by a device or a clamp.

The paper bag cutting device in the above-mentioned fruit bag removing device cuts the opening of the paper bag, which is tied to the peripheral surface of the fruit stalk, when the paper bag covering the outer surface of the fruit is peeled off from the peripheral surface of the fruit. The paper bag is cut off in advance to leave it open so that the paper bag can be removed from the outer surface of the fruit, and the paper bag can be removed from the outside of the fruit using a chuck provided on the underside of the conveyor that conveys the fruit with the bag attached. , the opening of the paper bag protruding from the fruit receiving seat of the conveyor to the lower side of the conveyor is held, and the paper bag is moved in the conveying direction of the conveyor to act on the paper bag cutter disposed on the lower side of the conveyor. Then, the opening part that is held in the zipper is cut off from the main body side of the paper bag, and the opening part that is cut off from the main body side of the paper bag is carried to a predetermined position by the zipper while being held in the zipper. , the chuck is released from the chuck by opening the clamping portion at the predetermined position.

By the way, the paper bag cutting device in this fruit bag removing device has a mechanism that opens when the opening part, which is cut off from the paper packaging body and carried out by the chuck, is released from the chuck by opening the gripping part of the chuck. (In many cases, the paper bag becomes attached to the gripping surface of one of the pair of gripping parts, so the chuck that performed the ejection operation moves again to the position where it grips the opening of the paper bag that covers the fruit, and the new paper bag is removed.) When the mouth part of the paper is being held, the part of the mouth part that was previously cut off from the main body of the paper packaging adhering to the clamping surface of the clamping part obstructs the clamping operation and prevents the mouth part from being held in the correct state. There is a problem that makes it impossible to do so.

An object of the present invention is to solve this problem, and in order to solve this problem, when the chuck opens its clamping part and releases the mouth part of the paper bag that has been carried out, is held in a state aQ in which the clamping portion is held so as not to move in the opening movement direction,
