<p>PROBLEM TO BE SOLVED: To solve the problem that a roof tile base loses a market value as its surface is easy to be marred and damaged at the time when it is derricked by a derrick mechanism and at the time when it is conveyed by a receiving conveyor by coming into contact with the derrick mechanism and the receiving conveyor as the surface of the roof tile base faces against the derrick mechanism. SOLUTION: This conveying line system of the roof tile base carries the derricked roof tile base W in a horizontal state by the receiving conveyor 20 by hanging the roof tile base W by a hanger 24 of a hanger conveyor 12 for glazing application so that a head H of the roof tile base W is directed downward, revolving the roof tile base W in the horizontal direction so that a back surface N of the roof tile base W is directed in the conveying direction, removing the revolved roof tile base W from the hanger 24 and derricking the roof tile base W on the receiving conveyor 4 by receiving it so that a surface P of the roof tile base W is directed upward.</p> |
