Abstract

PURPOSE:To provide the titled apparatus capable of clamping the paper bag surely, without damaging the fruit, by using a pair of clamping arms forced to be closed with a spring, and supporting the clamps in a manner to be separated upward gradually from the state wrapping the fruit. CONSTITUTION:The clamp (e) for clamping the paper bag is attached to the rotary holder 75 placed closely to the upper surface of the conveyor for transferring the fruit and circulating in a manner to be separated from the upper surface of the conveyor upward while moving along the transfer direction of the conveyor. A pair of clamping arms 85a of the clamp (e) are forced to close with each other by the spring 84 exerting a constant load and constant torque. The paper bag 3 covering the outer surface of the fruit 2 can be surely pulled off from the fruit by the clamp (e).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves placing bags of fruit harvested from fruit trees on a conveyor and transporting the fruits, and using a paper bag holding clamp disposed on the upper side of the conveyor to remove the outer surface of the fruit. By holding the paper bag that covers the fruit and pulling it out of the fruit,
This invention relates to improvements in a fruit bag removal device that removes paper bags from the outer periphery of bagged fruits.

In the above-mentioned fruit bag removal device, a clamp placed on the top side of the conveyor separates the paper bag from the outside surface of the fruit with a bag, which is placed on the top surface of the conveyor and is conveyed, and covers the outside surface of the fruit. In order to ensure the action of gripping the top of the
A blower device is installed on the underside of the con hair that blows pressure air toward the paper bag that covers the outside of the fruit, and the blower blows the paper bag that covers the outside of the fruit before the clamp grips it. When the paper bag is removed, it is raised from the outer surface of the fruit, and the clamp grasps the floating paper bag.

However, even with this method, if the paper bag that covers the outer surface of the fruit is wet or damp and is in close contact with the surface of the fruit, the paper bag may be removed from the outer surface of the fruit by the pressure air blown from the blower. There are cases where the paper bag does not float up, causing a problem where errors occur when the clamp is used to grab the paper bag.

The purpose of the present invention is to solve this problem, not only in the case of paper bags floating when a blower device for blowing up paper bags is also used, but also in cases where a blower device for blowing up paper bags is not used together. The object of the present invention is to enable a clamp to securely hold a paper bag covering the outer surface of a fruit without damaging the fruit. A clamp for holding the filter paper bag, which is a pair of clamping bodies that open and close to the left and right with respect to the conveying direction of the conveyor, is moved in the conveying direction of the conveyor from a position close to the top surface of the conveyor. At the starting end of the moving stroke, a pair of clamping members of the clamp or a side face of the fruit conveyed by the conveyor is attached to a rotary support body that rotates in a circular manner and has a moving stroke that moves upwardly away from the conveyor. In addition to supporting and installing it in a state where it looks like a lamp,
The clamp is characterized by being equipped with an opening/closing mechanism that closes the pair of holding bodies of the clamp together with a constant spring load during the movement stroke.

Next, an example of the implementation of the present invention will be described in detail with reference to the drawings, in which an air blower for blowing up a paper bag is combined with a fruit stem cutting device for cutting fruit stems to create a fruit stem cutting and bag removing device. Describe.
