DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a device for measuring the height of a line depressed in a carton.
BACKGROUND ART
If the bending torque of a carton's folding line (depressed line) is abnormal, then when the carton is loaded on a box manufacturing machine, a boxing machine or the like it may be unsatisfactorily opened or folded, or may be cracked. Accordingly, in order to eliminate such difficulties, it is necessary to measure the bending torque in advance, thereby to determine whether or not the bending characteristic is acceptable. However, the measurement of the bending torque takes a considerably long period of time. Therefore, a simple method has been employed in which the height of a depressed line which is in correlation with the bending torque is measured with a dial gauge or the like. More specifically, a specimen is inserted between the surface table and the measuring element, a zero reference is determined from a flat part of the specimen where no depressed line is formed, and thereafter the height of a depressed line is measured. And, in order to measure the height of the next depressed line, it is necessary to determine the zero reference again.
As is apparent from the above description, the method is disadvantageous in that as it is necessary to determine the zero reference for every depressed line, it still takes much time.
In view of the foregoing, this utility model is intended to provide a device which can automatically convey a specimen and automatically carry out the determination of a zero reference for every depressed line, the measurement of a depressed line height and the displaying and recording of the value of the height thus measured.
DISCLOSURE OF INVENTION
The foregoing object of the invention is achieved by the provision of a carton's depressed line height measuring device which has a function of automatically measuring the height of a depressed line from a sheet surface near the depressed line even if the sheet thickness of a specimen is varied, and a function of displaying the height of each depressed line.

BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of this utility model will be described with reference to the drawings.
As shown in FIG. 1, a roller 1 is provided to convey a specimen. The conveying roller 1 is coupled through a belt 3 to a drive motor 2. The roller 1 is rotated at a constant speed when a power button 4 is turned on.
Two sheet retaining rollers 5 are provided so that the measurement can be carried out even if the specimen is somewhat bent (FIG. 3). The rollers 5 are abutted against the conveying roller 1 by means of springs 6, respectively (FIG. 5). The part of the conveying roller 1, abutted against the sheet retaining rollers 5, is knurled to prevent the slip of the specimen. Instead of the method of knurling the part, a method may be employed in which the part of the conveying roller 1 is covered with a rubber lining.
A measuring section shown in FIG. 4 scans the specimen with a roller 7, and transmits the movement of the roller through a lever 8 to the core 10 of a diffe
