CONSTITUTION:The neck part of the paper bag 3 covering the fruit 2 placed on the transfer plate 12 is cut off with the paper bag cutting device during transportation, and the fruit stem is cut off with the stem cutting device. Air is blasted upward through the hole of the supporting bed 13 to effect the preliminary release of the paper bag 3 from the fruit, and the fruit is sent to the bag-removing device. The holding members 82, 82 are closed to clamp the bag 3 by the action of the clamp (e) placed at the upper part of the device. At the same time, air is blasted by the blower (d) upward into the bag 3 to send the paper bag between a pair of holding members 82, 82, and the bag is held with the paper bag stopper (g), clamped surely with the holding members 82, 82 and pulled up with the clamp (e) which is circulated along an orbit separating gradually from the conveyor. Even a paper bag wet with water and adhering closely to the fruit can be surely removed, and the clinging of the paper bag to the clamp can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for removing the outer surface of the fruit by grasping the bag that covers the outer periphery of the fruit with a clamp disposed on the upper side of a conveyor that conveys the fruit with the bag and pulling it out from the fruit. This invention relates to an improvement in a fruit removing bag that removes the bag from the fruit.

In the above-mentioned fruit unbagging device, a clamp disposed on the upper surface of the conveyor removes the outer surface of the fruit from the outer surface of the fruit with the bag placed on the upper surface of the conveyor. When it acts like grabbing a paper bag and pulling it up,
If the paper bag is wet or damp and is in close contact with the outer surface of the fruit, there is a problem in that it becomes difficult to grasp the paper bag. This problem was solved by installing an air blower on the bottom side of the conveyor, which corresponds to the position where the clamp performs the action of holding the paper bag, and blows pressure air against the bag that covers the fruit being conveyed by the conveyor. (This problem can be solved by blowing up the paper bag with this air blower when the clamp tries to grab the paper bag. The paper bag in
If the paper bag is blown high from the fruit so as to pass through the gripping part of the clamp, problems may arise in which the paper bag may be incorrectly held by the clamp or the paper bag may become entangled with the clamp, resulting in a druffle.

The present invention solves these problems and ensures that the paper bag is removed from the outer surface of the fruit by the clamp. When the paper bag is blown up at a certain height using the blower installed on the bottom of the container, the paper bag is blown up at a certain height and then the paper bag is clamped or grabbed. For this purpose, the fruit conveyed by the conveyor is placed on the downward side of the conveyor conveying the fruit in the bag.
