Abstract
Official abstract text for this publication.
In a device for detecting a paper splice part of a cardboard sheet and a device for producing a cardboard sheet, the device for detecting a paper splice part of a cardboard sheet, which detects a sheet paper splice part of a cardboard sheet that has a first sheet, a corrugated second sheet, and a third sheet bonded together, comprises: a sheet paper splice detection unit that detects the sheet paper splice part on the basis of the shape of the sheet and that is placed between a position at which sheets are spliced and a position at which the sheets are bonded in a sheet carrying direction; a marking device that marks the sheet paper splice part on the downstream side of the sheet paper splice detection unit in the sheet carrying direction; and a mark detection device that detects the mark on the downstream side of the marking device in the sheet carrying direction.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A paper splice part detection device of a cardboard sheet, which detects a sheet paper splice part in a cardboard sheet in which a first sheet, a corrugated second sheet, and a third sheet are bonded, the device comprising: a sheet paper splice detection unit disposed between a sheet paper splicing position and a sheet bonding position in a sheet transfer direction and detecting the sheet paper splice part, based on a shape of the sheet; a marking device that includes a crushing roller and is configured to assign a mark using the crushing roller to the sheet paper splice part on a downstream side in the sheet transfer direction from the sheet paper splice detection unit; and a mark detection device that detects the mark formed by the marking device on the cardboard sheet on the downstream side in the sheet transfer direction from the marking device, wherein the sheet paper splice detection unit is disposed between a dancer roll of a sheet paper splicing device and a preheater located upstream of a sheet bonding device forming a single-faced cardboard sheet laminates sheet. 2 . The paper splice part detection device of a cardboard sheet according to claim 1 , wherein the sheet paper splice detection unit detects the sheet paper splice part, based on a sheet thickness. 3 . The paper splice part detection device of a cardboard sheet according to claim 1 , wherein the marking device is disposed between a preheater of a sheet bonding device forming a single-faced cardboard sheet and a corrugating roll. 4 . The paper splice part detection device of a cardboard sheet according to claim 1 , wherein the marking device is disposed on the downstream side in the sheet transfer direction from a sheet bonding device forming a single-faced cardboard sheet. 5 . The paper splice part detection device of a cardboard sheet according to claim 1 , wherein the mark detection device is disposed on the downstream side in the transfer direction from a bridge in which the single-faced cardboard sheet stagnates.
