0-pur is the second separation conveyor that forms the core of the present invention,
It consists of a slat conveyor whose slope changes continuously from horizontal to steep. This slat conveyor is powered by a motor (+4
) A conveyor plate θ8) made of an elongated rectangular steel plate is brought close to the chain αη which is circulated between the driving chain wheel 0υ and the driven chain wheel OO driven by the chain αη and parallel to each other in a direction perpendicular to the chain αη. They are arranged and fixed in an endless manner without any breaks, and the inclination is almost horizontal at the starting end 09, gradually increasing the inclination, and becomes a steep inclination close to vertical near the terminal end (A). The conveying plate a barrel of this slat conveyor is provided with anti-slip protrusions 121) at regular intervals. The anti-slip protrusion Cυ is rod-shaped with a substantially rectangular cross section, and is fixed to the surface of the conveying plate α8) parallel to its longitudinal direction. The height of the anti-slip protrusion η is preferably slightly lower than the thickness of the cut product (a). Installation interval of anti-slip protrusions d
is determined as appropriate depending on the size of the cut product to be processed. The anti-slip protrusion 01) may be provided over the entire width of the conveyor plate 08) to which it is fixed, or may be provided only on a portion thereof.

[Operation J] Next, the operation of the apparatus for separating and supplying plate-shaped objects of the present invention will be explained.

The cut products obtained by cutting steel plates with a gas cutting machine are stored in a bucket container (4) in a disorderly manner and are transported by a forklift or the like, and the bucket container (4) is placed on a rotating table (3). and fixed hydraulic cylinder (5),
(5)', it is fixed to the rotating table (3). When the rotating hydraulic cylinder (7) is operated to rotate the rotating table (3) and the bucket container (4) together as shown by the chain line around the fulcrum (2), the inside of the bucket container (4) is rotated. The cut products fall onto the guide plate 00 and are piled up at the starting end of the first separation conveyor 00. The bucket container (4) is not overturned all at once, but is divided into several times, gradually increasing the overturning angle, and the cut products on the bucket container are transferred to the first separation conveyor in several times. Good.

When the first separation conveyor moves slowly and continuously or intermittently by a certain distance, the cut products are transferred to the second separation conveyor α1.
The particles fall little by little at the starting end θO and pile up.

The first separation conveyor α■ is operated continuously and moves once with the cut products on it, and as the slope of its conveyor plate (b) gradually increases, the stacked cut products (i.e. )
The items on the bottom layer are carried to the end of the steep slope (E) as the transport plate α8) of the slat conveyor moves without being caught on the anti-slip projections, but the cut items stacked above In (a), when the slope becomes large, it slides toward the starting end.

As a result, the cut products are transported one by one while being locked to the anti-slip protrusions Cυ provided at regular intervals on the conveyor plate (G) of the slat conveyor, and the cut products are transported one by one at regular time intervals. Cut products that slide from the terminal end (1) of the slat conveyor over the top, slide on the guide plate (a), and fall onto the carry-in conveyor (c) are transported by the carry-in conveyor (c) to the processing equipment.
