る。When producing a small cardboard box with a length (l) and a box depth (h), one sheet with a length of 2 sheets (2l) is transferred from the paper feed section (1) to the flexographic printing section. Transfer to (2) for printing, then transfer to creaser slot (4) for groove processing, contour processing, crease processing, etc., then transfer to die cutter section (3) for groove processing, contour processing In addition to drilling, etc., cut along the cutting line (a) and divide one sheet with a length of 2 (2 l) into a sheet (A) and a sheet (B). Then, the sheet is conveyed to the sheet separating / conveying device (7). At this time, in the sheet separating and conveying device (7), among the vertical feed rolls (7a) (7b) (7c), the vertical feed roll (7a) on the upstream side in the transport direction and the vertical feed rolls ( 7b) and rotate at the same speed,
The vertical feed rolls (7c) on the downstream side in the conveying direction are rotated at a speed faster than the vertical feed rolls (7a), (7b) by the speed change mechanism, and the preceding sheet (A) is followed by the succeeding sheet (B). The sheets (A) and (B) are separated from each other, and a space is formed between the sheets (A) and (B), and the sheets (A) and (B) are delivered in that state to the folder gluer section (5) on the downstream side in the transport direction. At this time, the vertical feed rolls (7b) in the central portion are slid around the drive shaft (7b ') by the one-way clutch (7b ″), and the peripheral speed of the vertical feed rolls (7b) in the central portion is increased. Becomes the same as each vertical feed roll (7c) on the downstream side in the transport direction.

ときの生産性を向上できる。(Effects of the Invention) As described above, the sheet separating / conveying device of the box making machine of the present invention separates a sheet separating / conveying device when a preceding sheet and a succeeding sheet are conveyed to the sheet separating / conveying device in a beading state.
In the transporting device, among the vertical feed rolls, the vertical rolls on the upstream side in the transport direction and the vertical feed rolls in the central portion are rotated at a constant speed, while the vertical feed rolls on the downstream side in the transport direction are changed by the speed change mechanism. It rotates at a speed faster than the vertical feed roll, separates the preceding sheet from the following sheet, forms a gap between each sheet, and keeps each sheet as it is in the folder direction on the downstream side in the transport direction. Send to. At this time, each vertical feed roll in the central portion slips around the drive shaft by the one-way clutch, and the peripheral speed of each vertical feed roll in the central portion becomes the same as that of each vertical feed roll on the downstream side in the transport direction. Therefore, at the low speed operation of the box making machine, which does not cut the sheets, the length of 2 sheets (2l) is 1
1 + 1 for the die cutter to feed a single sheet
Even if the preceding sheet and the subsequent sheet are cut into a single sheet and sent to the separating / conveying device in a pile-up state, the preceding sheet and the subsequent sheet are fed and printed in the folder gluer section and the counter section. Number of sheets fed per set / Double the number of sheets / min /
Therefore, the productivity can be improved when a small cardboard box is produced.
