Abstract
A loading device for a horizontal continuous furnace for the heating of glass plates comprises a roller conveyer (6) as part of a continuous conveying system. Support strips (12-15, 32-35) can be lowered and are arranged between conveying rollers (7) of the roller conveyer at a feed station (A). The glass plates (2, 3, 4, 5) are placed on the raised support strips (12-15, 32-35) and are lowered onto the conveying rollers at a preset time by simultaneous lowering of all support strips. Each support strip (12-15, 32-35) is supported independently of the other support strips on separate lifting devices (16-19, 36-39). These lifting devices (16-19, 36-39) are controlled by reflecting photoelectric barriers (22-25, 42-45) respectively dedicated to each support strip such that each support strip (12-15, 32-35) is individually raised to an upper position as soon as a glass plate transferred to the conveying rollers (7) has left the area of that support strip. Glass plates (4, 5) coming from another feed station (B), located upstream, pass below the raised support strips (14, 15) while, simultaneously, the next glass plates can be placed on these same support strips (14, 15).
