Полезная модель относится к производству оборудования для стекольно-ситалловой промышленности, а именно к устройствам и транспортерам, предназначенным для разгрузки стеклотары из печей отжига и последующей ее передачи для прохождения технологического процесса. Основной частью этих устройств является каркас секции транспортера разгрузки стеклотары, примыкающий непосредственно к транспортеру печи отжига перегружающего отожженную стеклотару. Известные конструкции, как правило, выполнены с транспортирующими многорядными пластинчатыми цепями. Перегрузка на них стеклотары с транспортера печи отжига производится ее перемещением напором задних слоев на впередистоящие через передающие столики и сопровождается наличием стеклобоя, образующегося как в печи отжига, так и при перемещении стеклотары, что снижает надежность выполнения технологического процесса разгрузки. Технический результат от полезной модели получен в результате совершенствования конструкции каркаса секции транспортера разгрузки стеклотары, обеспечивающей повышение надежности выполнения технологического процесса разгрузки стеклотары с транспортера печи отжига стеклотарного предприятия. 1 з.п. ф-лы, 6 ил.

A cleaving apparatus holds at least one surface (effective surface) of a band-like glass film in a non-contact state to suppress a situation that wavy portions reach a region in which the band-like glass film is to be cleaved. The cleaving apparatus cleaves the band-like glass film, which is being conveyed in a longitudinal direction thereof, along a conveyance direction thereof using a thermal stress generated through localized heating and cooling of a heated region. The localized heating and the cooling is performed on a preset cleaving line extending along the conveyance direction of the band-like glass film. The cleaving apparatus includes an air knife for supplying air to a front surface of the band-like glass film to retain the film on a conveyor at a position on an upstream side of a cleaving region in the conveyance direction.
