DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sequentially transporting tiles, which have been aligned and transported in one direction, by turning a certain number of tiles in the direction at right angles in the middle and sequentially.

[0002]

2. Description of the Related Art A conventional right-angle turning transfer device of this type is provided at a terminal portion of a belt conveyor which circulates and runs two narrow endless belts arranged in parallel at a predetermined interval.
The start end of the roller conveyor, in which the direction of conveyance is perpendicular to the belt conveyor in which a plurality of rotationally driven rollers are arranged at intervals, is connected so that the endless belt enters the gap between the rollers, and the end of the belt conveyor Part of the endless belt can be moved up and down on the upper and lower surfaces of the roller conveyor, and the tiles are conveyed in one direction by the belt conveyor. When a certain number has accumulated on the upper part, the vertically moving part is lowered to the lower surface of the conveying surface, and the tile on the vertically moving part is transferred onto the conveying surface of the roller conveyor, and the belt is moved by the roller conveyor. 2. Description of the Related Art There is known a structure in which a conveyor is continuously conveyed in a direction perpendicular to a conveying direction of a conveyor.

[0003]

However, in the conventional apparatus, after the vertical moving portion of the endless belt of the belt conveyor falls on the lower surface of the conveying surface of the roller conveyor, the tile is transferred onto the starting end of the roller conveyor. If the next tile is continuously transported on the belt conveyor until the tile is transported a fixed distance on the roller conveyor and the vertical moving part of the endless belt rises again to the upper surface of the transport surface, the first tile will be rolled. Projection on the conveyor may cause collision with tiles on the roller conveyor.

[0004] In order to avoid such collisions, the tiles on the belt conveyer are used until the vertically moving portion of the endless belt is lowered from the lower surface of the convey surface of the roller conveyor to the upper surface of the convey surface again. Therefore, it was necessary to take measures such as stopping the transportation, and the efficiency of transportation was poor.

[0005]

SUMMARY OF THE INVENTION A right-angle turning and conveying apparatus for tiles according to the present invention has been completed in order to solve the above-mentioned problems, and has left and right side edges of a tile at the end of a belt conveyor. A long and narrow stock member that can be supported and placed on the belt conveyor along the transport direction has been conveyed by the belt conveyor when the vertical moving part of the endless belt falls below the lower surface of the transport surface of the roller conveyor. Support the left and right side edges of the tile, and, along the transport direction of the belt conveyor, at a height that allows the tile to be transferred onto the vertical movement part when the vertical movement part is placed on the upper surface of the transport surface. The apparatus is configured to be able to advance and retreat at a certain timing above the conveying surface of the roller conveyor.

[0006]

When a certain number of tiles conveyed by the belt conveyor accumulate on the vertical moving part of the endless belt, the vertical moving part falls on the lower surface of the conveying surface of the roller conveyor and the tiles on the vertical moving part are removed. It is transferred on a roller conveyor and transported at right angles by the roller conveyor, but as the vertical moving part goes down, the tiles that have been subsequently transported by the belt conveyor are supported on the left and right side edges. The stock member is placed on the stock member side, and the stock member gradually advances above the roller conveyor in synchronization with the running of the belt conveyor until the vertical moving portion rises again to the upper surface of the conveying surface of the roller conveyor. The transported tiles are stocked on the stock member.

[0007] When the tiles transferred on the roller conveyor are conveyed at a right angle at a fixed distance and the vertical moving part of the endless belt rises to the upper surface of the conveying surface of the roller conveyor, the tiles stocked on the stock member are removed. The stock member is moved upward while being lifted from below by the raised vertical moving portion, and the empty stock member is retreated to the original position.

[0008] The tiles subsequently conveyed follow the tiles transferred from the stock member, advance on the vertically moving portion of the endless belt, and are conveyed sequentially, and the above-described operation is repeated.
