According to a first aspect of the present invention, there is provided a tray for carrying a large number of objects having a bottom surface thereon. When air having a predetermined pressure is sent from below to above through a large number of through holes on the entire surface of the mounting plate, the transferred object floats. When the tray is tilted in the inclined direction in this state, the transferred object slides down. The two conveyed objects are prevented from being displaced in the carrying-in direction by the two partition plates that are parallel to the inclined direction and open upward. Two holding plates connected to the partition plate and having outer surfaces that are parallel to and perpendicular to the tilt direction,
When a large number of book trays are continuously conveyed by the carry-in conveyor, overlapping of the book trays is prevented.

The second invention is an apparatus for taking out the object to be transported from the tray. A plurality of book trays are transported in the loading direction by the loading conveyor, and the trays are successively transported to the take-out device. The main tray, which has been carried into the take-out position by the tray tilting mechanism, is fixed and tilted in the tilting direction. Air of a predetermined pressure is supplied from below the mounting plate of the tray through a through hole by an air pressure supply device. The conveyed object floats up by the tray tilting mechanism and the pneumatic supply device and loses direct contact with the main tray, and is taken out without being damaged or broken. The transferred object is transferred to the receiving conveyor. The empty tray returned horizontally by the empty tray return mechanism at the removal position is carried out from the removal position.

According to a third aspect of the present invention, as shown in FIG. 7, the carry-in conveyor has two or more take-out positions, and each of the take-out positions has a tray tilting mechanism, an air pressure supply device, a receiving conveyor, and an empty tray returning mechanism. It is. If the ability to take out this conveyed object at each take-out position is the same, as long as the carry-in conveyor is sufficient to carry in this tray,
The ability of this apparatus to remove the object is the capacity of the apparatus according to the second invention multiplied by the number of removal positions.

According to a fourth aspect, as described in the second and third aspects, the transported object is taken out of the tray, and
Further, the empty tray with dirt and clogging carried out by the empty tray return mechanism is cleaned by the mechanism for cleaning the added main tray.

In the fifth invention, two endless belts are used.
This is because the separation stopper and the air blow tank pass over the upper surface of the carry-in conveyor. The reason why the leading end stopper and the separation stopper are required for the carry-in conveyor is that the main tray is fixed at the take-out position and that the main tray at the take-out position does not rub against the next tray when tilted.

The reason why the air blow tank is used in the sixth invention is to buffer the supplied air pressure to a constant pressure. The reason that the lower portion of the mounting plate and the open surface of the main tank are in close contact with each other is to eliminate waste caused by leakage of supplied air. The reason why the spindle in the main tank is located at the center of gravity of the surface parallel to the tilt direction of the main tank is to eliminate waste of rotation of the main tank in the tilt direction. The holding bar was used to fix the lower portion of the mounting plate and the open surface of the main tank so that the main tray would not slide down when the main tray was tilted.

In the seventh invention, the main tray is carried out at the height of the empty tray return because the main tray is not removed from the take-out position and the obstacle at the reference height of the take-out position disappears, and the next tray is removed. This is because the tray can be started to be carried into the take-out position. As a result, the interval for taking out the object to be conveyed from each book tray at the take-out position is shortened, and the take-out capacity is increased accordingly.

The eighth invention has the function of combining the functions of the fifth to seventh inventions in the apparatus of the second invention and the third invention.

The ninth aspect of the present invention has a strong effect when the object to be conveyed causes clogging of the through hole of the tray. Brush the empty book tray with a vertical rotating brush to float the debris, dust, and slag of the conveyed object, and then suction them with a vertical suction cleaner. It has the same function and effect as when using this tray.
