AUTOMATIC PILING DEVICE FOR SINGLE-FACED CORRUGATED BOARD

摘要

PURPOSE:To improve the working speed and quickly conform with a dimensional change of a sheet by regulating the position of a lifting belt at the time of superposing a plurality of single-faced corrugated board sheets advanced and supplied in parallel to each other in a reasonable form to form a trough form. CONSTITUTION:Of two processed sheets A, A' advanced in parallel to each other, the part closer to the center line of the left sheet A is lifted by a traveling belt 17. Their outside edges are guided by guide plates 16, 16 and gathered to the center side to gradually increase the superposing degree by induction roll pairs 31, 31', 31'' and a pressing roll 32, and the sheets are superposed to each other in the width dimension of the sheet A by a width gathering guide belt. The sheets are reversed so that the flute side is turned down, and the lower surface is supported on its center line by a belt 64, the upper side is pressed by a belt, and both the sides are lifted to the degree as being advanced by side lifting belts and curved into a trough form. Even if the sheet A is narrow and long, the contact position with the sheet A lower surface of the lifting belt is laid closer to the center line side, whereby the sheet can be piled up on a stacker 50 without hindrance.
