Description

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

In the above-described fruit unbagging device, the clamps disposed on the top side of the conveyor remove the bag from the outside of the bagged fruit placed on the top of the conveyor and transported.
When trying to grab the paper bag that covers the outside of the fruit and pull it up, if the paper bag is wet or wet and clings to the outside of the fruit, it will be difficult to grab the paper bag. There's a problem. This problem can be 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 clamping the paper bag, and blows pressure air against the bag that covers the fruit being conveyed by the conveyor. This can be solved by keeping the paper bag in place and blowing it up with this air blower when the clamp tries to grab the paper bag. The paper bag blows up high from the fruit, passing through the grip of the clamp.
Problems may arise in which errors may occur when the paper bag is held by the clamp, or the paper bag may become entangled with the clamp, causing trouble.

The present invention aims to eliminate these problems and ensure that the paper bag can be removed from the outside of the fruit by the clamp. When the air blower installed on the underside of the conveyor blows up the air, the air is blown up to a certain height, and the paper bags that are blown up to that certain height are grabbed by a clamp. For this purpose, a blower device is provided on the bottom side of the conveyor that conveys the fruit with bags, and blows pressure air against the bag that covers the fruit being conveyed by the conveyor, and on the top side of the conveyor, the A paper bag stopper is provided to hold the paper bag blown up from the outer surface of the fruit by the air blower to a predetermined height position relative to the fruit, and a clamp for gripping the paper bag that covers the fruit is moved upward relative to the top surface of the conveyor. It is characterized in that it is supported by a rotating support body that rotates in the conveying direction of the conveyor while being separated from the conveyor.
