Abstract:
An automatic inspection device for a corrugated paperboard machine includes comprises a position setting section for setting movable members to positions within moving ranges; a control section for driving each of the drive motors at a given rotational speed so as to allow a respective one of the movable members to be moved within a corresponding one of the moving ranges; a current detection section for detecting a drive current being supplied to each of the drive motors when the drive motor is driven at the given rotational speed; and a current determination section for determining whether the drive current of each of the drive motors exceeds a given threshold. The automatic inspection device is configured to, when the current determination section determines that the drive current of a specific one of the plurality of drive motors exceeds the given threshold, detecting that a defect occurs in the movable member.
Abstract:
Disclosed are a corrugated paperboard cutting control apparatus and a corrugated paperboard cutting control method. Under control of a cutter control device (110), a camera (CA) images a flute arrangement state in a cut section LE of a corrugated paperboard after being cut. A lower-level management device (100) acquires a result of the imaging from the camera. Then, the lower-level management device performs: a phase determining processing of, based on the acquired imaging result, determining a flute arrangement phase located at an actual cut position within one flute pitch; a directive sheet length setting processing of adjusting a preset order-specified sheet length (L) in such a manner as to allow the flute arrangement phase determined through the phase determining processing to come closer to a preset reference flute arrangement phase, to thereby set a directive sheet length (Ln) having a value equal to an integral multiple of the flute pitch; and an instructing processing of giving an instruction to designate the directive sheet length set through the directive sheet length setting processing, to a cutting apparatus.
Abstract:
A corrugated paperboard sheet manufacturing apparatus (1) comprises a single facer (8) for preparing a single-faced corrugated paperboard sheet (6), a double facer (12) for preparing a double-faced corrugated paperboard sheet (12), a slitter-scorer (17) for performing a scoring and a slitting of the double-faced corrugated paperboard sheet (10), a cutter (20) for cutting the double-faced corrugated paperboard sheet (10) after the scoring and slitting, and a printer (18) for printing individual identification information on the double-faced corrugated paperboard sheet, in a non-contact state. The printer (18) is disposed on a conveyance line of the corrugated paperboard sheet manufacturing apparatus (1) at a position on a downstream side of the double facer (12).
