Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vegetable sorting conveyor, and can be used in long vegetable sorting machines, processing machines, etc.

Problems to be Solved by the Prior Art and the Invention For example, the thickness, length, etc. of long vegetables such as burdock are detected while being transported laterally, and the detected values are used to sort the vegetables into size classes. When taking out long vegetables, it is necessary to align the root, etc. with a reference position in order to detect the thickness, length, etc. of long vegetables. A horizontally long vegetable receiving rack with multiple vegetable receivers.
When a worker grasps the thick end of long vegetables and places them one by one from above on each receiver, when placing the vegetables in a hurry to increase efficiency, the worker should hold one end of the vegetable at the reference position on the receiving rack. Even when placed, the foot side may be placed on the front or rear receiving rack in the transport direction, resulting in incorrect sorting.

In addition, instead of grasping and placing books on the receiver, you can push multiple books onto the receiver with one hand and place them on the receiver, aligning the end of each book with the reference position with the other hand. From the standpoint of improving work efficiency, it was desirable to have something that could be placed correctly on the right and left sides of the receiver.

Means for Solving the Problems The present invention provides a system in which each receptacle (3) of a sorting conveyor (8) is arranged to transport long vegetables (4) in a horizontal position, while falling down and sorting them. , this sorting conveyor (8)
The supply table (5) is moved upward so as to approach the supply edge (A) of the supply table (5) to which the long vegetables (4) are supplied, and the supply edge (A) of this supply table (5) is A terminal end portion of the test receiving portion (6) which is provided to receive and move the long vegetables (4) that are engaged and transferred by the receptor (3) from the portion (a) to an appropriate position in the forward direction of transfer (b).
