PURPOSE:To prevent a board-like body from being unevenly piled by providing a detector which detects the end part position of said board-like body being conveyed and varying the delivery speed of a board-like member delivery part in accordance with the timing for the following process, based on the output of said detector. CONSTITUTION:When the captioned device is applied to a sendout conveyor 10 for a corrugated box making machine, a sheet of corrugated board 11 is punched by a rotary die cutter 6 and conveyed in a longitudinally divided condition as in (1) (2), (3) (4), (5) (6). In this case, the rotation speed V3 of sandwitch rolls 34 is obtained by detecting the timing at which the end part position of a punched sheet 11'' passes through by means of a photo tube 32, to variably control the rotation speed of the rolls 34. That is, while a sheet (1) is passing through the photo tube 32 part, the roll 34 is driven at V3=V2, and, after the sheet (1) has passed through, the gap DELTAl between the sheets (1) and (2) is detected and, when the top end of the sheet (2) has intercepted the light for the photo tube 32, the rotation speed is decelerated to V3=V1, i.e., (2l/L)XV2. |
