Abstract

A slotter apparatus (30), comprising: a slotter knife (36) provided so as to rotate in the same direction as a conveyance direction (TD) of a sheet (10) that is conveyed on a conveyance path, the slotter knife (36) being such that a cutting edge for forming a notch groove (12) in the sheet (10) is provided to the outer periphery of the slotter knife (36); a protruding part (38) provided so as to protrude outward from the cutting edge at one end of the slotter knife (36), the protruding part cutting an end part (14) of the notch groove (12) by piercing the sheet (10); a drive device (60) that drives the slotter knife (36) so as to rotate; and a control device (70) that, at least when the protruding part (38) passes through from the upper surface of the sheet (10), controls the relative relationship between the circumferential velocity of the slotter knife (36) and the conveyance velocity (Vs) of the sheet so that the protruding part (38) does not interfere with the end part (14) of the notch groove (12).

Description

technical field [0001] The invention relates to a slotting device and a box making machine for forming notches on corrugated cardboard in a corrugated paper box making machine. Background technique [0002] In a conventional box-making machine, the paper feeding section conveys corrugated cardboard (hereinafter referred to as "cardboard") one by one to the printing section, and the printing section performs specified printing on the cardboard, and then, the paper discharge section and the punching section perform crimping on the cardboard , slotting, pasting processing, opening holes, etc., to be processed into cardboard for box making. Then, while moving the cardboard, the folding unit applies paste to the pasted place, folds along the ruled lines, and joins the pasted place. Thereby, the corrugated cardboard box in the folded state is completed, and is transported to the counting and discharging unit. The corrugated cardboard boxes in the folded state are stacked at the ...
