Abstract

PURPOSE:To enable the sure removal of a covering paper bag from a fruit even if the bag is wet and attached closely to the surface of the fruit, by holding the paper bag with a clamp, and swinging the bag. CONSTITUTION:The mouth of the paper bag 3 covering the fruit 2 placed on the transfer plate 12 is cut off, compressed air is blown through the nozzle (d) upward toward the fruit-supporting plate 13 of the plate 12 to release the paper bag 3 from the outer surface of the fruit 2, the fruit 2 is transferred under the rotary holder (f) extended between the rotary shafts 70-72, and the roller 82 at the base end of the clamping arm 80 of the clamp (e) supported by the chain 74 is pressed with the guide rail 83. The clamping parts 85 at the far end of the clamping arm 80 are closed and the paper bag 3 is clamped by this action. The inner surface of the chain 74 is made to contact with the contacting part 90 of the swinging device (g) attached to the rail 83, and the clamp (e) is swung by the link plate 74a to remove the fruit 2 from the paper bag 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention removes a bag placed over the outer circumference of a fruit by grasping it with a clamp provided on the top side of a conveyor that transports the fruit with the bag and pulling it out from the fruit. This invention relates to an improvement in a fruit bag removal device.

To remove the bag from the fruit using the above-mentioned fruit bag removing device, the clamp of the bag removing device disposed on the top side of the conveyor's transport path is placed on the fruit with the bag and transported on the conveyor. This is done by grasping the paper bag on the outside of the fruit and rotating it away from the fruit. If the fruit is stuck tightly to the paper bag and difficult to separate, the fruit may be lifted up together with the paper bag, causing damage to the fruit or carrying the fruit to the discharge side of the paper bag.

The purpose of the present invention is to propose a new means for solving this problem.

The means of the present invention for achieving this object includes a clamp for grasping a paper bag that covers the fruit, which is placed on the top side of a conveyor that conveys fruit with bags, while moving upwardly away from the top surface of the conveyor. The present invention is characterized in that it is disposed so as to be supported by a rotary support that rotates in the conveyance direction of a conveyor, and is provided with a vibration device that vibrates the clamp, thereby forming a fruit bag removal apparatus.

Next, an embodiment of the present invention will be described in detail with reference to the drawings, in which an embodiment of the present invention is combined with a fruit stem cutting device for cutting fruit stems to form a fruit stem cutting and bag removing device.
