Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides harvested fruit with a bag and stem,
The fruit is placed on the fruit receiving section of the conveyor with the fruit stem protruding downward through the hole in the fruit receiving section, and the fruit is conveyed, and during the conveyance process, the fruit stem is cut into short pieces. In a fruit unbagging and fruit stem cutting device that removes the bag at the same time, as a pretreatment for removing the bag placed on the fruit, the mouth of the bag is opened to open the bag that is closed with a stopper. This invention relates to an improvement in a device for cutting the opening of a bag.

In the above-mentioned fruit unbagging/culp cutting device, as a pretreatment for removing the bag placed over the fruit from the fruit, the work of cutting and removing the opening of the bag to open the bag is performed. , is a fruit stem gripping device that is placed so as to face the movement trajectory of the fruit placed on the fruit receiver of the conveyor and conveyed by the operation of the conveyor. This is done by using a cutter while holding and pulling out the fruit stalk, and cutting off the entire fruit stalk or just the opening of the bag, leaving the fruit stalk intact.

From this, the cutter that cuts the opening of the bag is pulled downward by the stem gripping device, and the clip (the wire made of soft metal that binds the opening of the bag) is pulled downward. Although there should be no problem of interference or uneven length of the remaining stalks that are cut together with the opening of the bag, such problems have occurred in the past.

The present invention solves this problem by:
After conducting various studies, we found that the action of pulling out the fruit stem by the fruit stem gripping device is such that the holding part of the fruit stem gripping device moves synchronously with the conveying direction of the conveyor while holding the fruit stem. The amount of downward movement of the gripping part is constant, but it depends on the state in which the fruit is placed on the fruit receiving part and the shape of the fruit. ,
Since the root part of the fruit stem is in a state floating above the upper surface of the fruit receiving part, the clamping position of the clamping part with respect to the fruit stem changes in the protruding direction of the fruit stem, and this change It was discovered that the fruit stem gripping device was not pulling out the fruit sufficiently, causing the above-mentioned problem. The purpose of this is to maintain a constant clamping position of the clamping part relative to the fruit stem when the clamping part is pressed against the upper surface of the receiving part.

In order to achieve this object, the device of the present invention is provided with a device for grasping the fruit stem portion on the upper side of the conveyance path of the conveyor in the bag opening cutting device in the above-mentioned fruit unbagging and fruit stem cutting device. The holding part is characterized in that a pressing body is disposed directly above the position where the fruit stem part is held, for pressing the fruit to be placed on the fruit receiving part against the upper surface of the fruit receiving part. be.
