The individual rollers of the group are arranged so as to be retractable from the level of the upper surface of the belt, and when an article to be sorted arrives, the roller group is driven to project from the level of the upper surface of the belt to drive the article in the driving direction of the belt. In one direction at a right angle for sorting, and then the roller group is sunk from the level of the upper surface of the belt in preparation for the arrival of the next article.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the former article transporting apparatus, in order to change the transporting direction of the article 2, the distribution conveyor 3 connected to the transfer belt conveyor 1 for transporting the article 2 must be moved up and down. In addition, as the conveying direction of the article 2, it is not possible to simultaneously carry out the distribution and transfer of the one that moves straight and the one that changes the direction at a right angle. In the latter separating device, when the roller group projects from the level of the upper surface of the belt and sends out the article in one direction at right angles to the driving direction of the belt, the next article hits the tip of the projected roller group. Since the movement is hindered, the roller group must be temporarily sunk from the level of the belt upper surface in preparation for the arrival of the next article, which is good for sorting and sorting the individual articles, but changing the article conveyance route. It was not suitable for continuous transport.

An object of the present invention is to continuously convey articles on the same plane in a straight or right-angled direction by arbitrarily changing the conveyance route, and at the same time to continuously distribute the articles in the straight-ahead and right-angled directions. An object of the present invention is to provide an article transporting device.

Means for Solving the Problems The present invention is an article transporting device in which a transporting conveyor and a separating device are arranged in the order of the transporting direction of an article, and then the transporting conveyors are respectively arranged corresponding to the separating and transporting direction of the article.
