Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a harvested fruit with a bag and a stalk is placed in a fruit receiver of a conveyor, and the stalk of the fruit protrudes downward through a hole in the fruit receiver. In a fruit unbagging and stem cutting device that cuts the fruit stem short and removes the bag during the conveyance process, the fruit is transported while being placed on the fruit. The present invention relates to an improvement in the bag cutting device R, which cuts the opening of the bag in order to open the bag that is closed with a stopper.

[-J
The process of cutting and removing the opening of the bag to open the bag is a process that involves cutting and removing the opening of the bag, which is carried out on the fruit tray of the conveyor. A stalk gripping device placed facing the moving trajectory grips the stalk and pulls it out while a cutter is applied to remove the whole stalk or just the mouth of the bag with the stalk left behind. This is done by cutting out the

From this, the cutter that cuts the opening of the bag is pulled downward by the stalk gripping device, and the cutter is pulled downward. There shouldn't be any problems such as interference with the wire (wire) or uneven length of the stems that are cut together with the opening of the bag, but in the past, such problems have occurred. .

In order to solve this problem, the present invention has conducted various studies and found that the pulling out action of the fruit stem by the fruit stem gripping device is based on the fact that the holding part of the fruit stem gripping device pinches the fruit stem. This is due to the operation of moving downwards with respect to the fruit receiver while moving in synchronization with the conveyance direction of the conveyor, and although the amount of downward movement of the gripper is constant, the fruit does not reach the fruit receiver. Due to the state in which the fruit is placed and the shape of the fruit, the root part of the fruit stem is in a position floating above the fruit receiving part, so that the gripping part of the holding part relative to the fruit stem is in the position 1 of the fruit stem. It was found that the protruding direction of the fruit stem changed in the protruding direction, and that this change made the fruit stem part insufficiently pulled out and caused the above-mentioned problem. When doing so, the fruit placed on the fruit holder is pressed against the first side of the fruit holder, and the gripping position of the holding part relative to the fruit stem is kept constant. That is [1 point].

The apparatus of the present invention to achieve this object is such that, in the bag mouth cutting device in the above-mentioned fruit bag removal and fruit stalk cutting device, the fruit stalk portion is gripped on the upper surface side of the conveyance path of the conveyor. A pusher for pressing the fruit to be placed on the fruit receiver against the upper surface of the fruit receiver is disposed directly above the position where the clamping portion of the device clamps the fruit stalk. Next, an example of implementation will be described with reference to the drawings.
