[0079] Below, refer to Figure 4 A third embodiment of the present invention is explained. Figure 4 shown corresponding to figure 1 , the box manufacturing line of the present embodiment. exist Figure 4 Among them, a pair of transfer rollers 81a and 81b are arranged to be inserted into the conveying line PL of the corrugated board sheet on the immediately downstream side of the upper and lower cutting rollers and transfer the cut small corrugated board along the transfer direction a of the corrugated board sheet Slices 1 and S 2. The transfer roller 81a is connected to the output shaft of the servo motor 82 and is rotated by the servo motor. The transfer roller 81b is a driven roller and guides the small corrugated sheet S passing the transfer rollers 81a and 81b in the transfer direction a 1 and S 2 .

Abstract

Disclosed is a method for producing a cardboard box by performing a box-making process of a corrugated cardboard sheet which is formed to have dimensions of a plurality of cardboard boxes wherein the yield of the cardboard sheet and the production efficiency are enhanced and a countermeasure can be taken against paper powder. A method for making a box of a corrugated cardboard sheet by performinga box-making process of a cardboard sheet (S) which is formed to have dimensions of a plurality of cardboard boxes and then cutting the cardboard sheet (S) into dimensions of one cardboard box comprises a step (I) for cutting the cardboard sheet (S) into dimensions of one cardboard box by a cut line (k) in the direction intersecting the conveyance direction (a) along a box making line (PL) after a ruling and grooving step (C) and before a pasting and folding step (E), and a speed increase step (J) for spacing the cardboard sheets (S1) and (S2) thus cut by a set dimension following to the cutting step (I) by increasing the speed of the cardboard sheets (S1) and (S2) while conveying toward a subsequent step.

Description

technical field [0001] In an apparatus for producing boxes of corrugated board, the present invention relates to a method and an apparatus for producing boxes of corrugated board, wherein by performing a box production process of a board formed in a plurality of corrugated board box sizes And cutting the sheet into individual pieces each having the size of one corrugated board box enhances box production accuracy and processing efficiency. Background technique [0002] Corrugated sheet made by a corrugator mill is processed on a conveyor line of a box production machine to be printed, crimped and grooved, and then formed into a square tube in a gluing step and a folding step in which, The glued edges of one side panel of the four-panel box are overlapped and glued to the other side panel to form a body having the shape of a square tube, and flaps extending from each panel form the bottom and top portions of the box. [0003] Figure 5 Shows the general structure of the box ...
