の局部的変形、圧痕、誤検出の原因となる。By the way, the inner peripheral edge of a metal strip coil such as a steel strip may hang down due to its own weight or curling. Especially, when the metal strip becomes thin, the inner peripheral edge of the coil may hang down. It will be quite large. FIG. 5 exemplifies the manner in which the inner peripheral edge of the metal strip coil hangs down.
In the figure (A), when the tip of the inner peripheral end 1-1 of the metal strip coil 1 hangs down, but is in contact with the coil inner peripheral wall, the figure (B) shows the space where the inner peripheral end 1-1 is the inner peripheral coil. This is the case when it hangs on the part. When detecting the step of the inner circumference of the metal strip coil in which the inner circumference end of the coil hangs down and a gap is generated between the coils as described above, an excessive load is applied to the step detection device and the step is detected. Not only cannot be carried out smoothly, but it also causes local deformation of the coil, indentation, and erroneous detection.

An object of the present invention is to provide a device capable of detecting a step difference on the inner circumference of a metal strip coil so as to prevent the occurrence of the above.

出を行う。The automatic inner circumference wrapping device for a metal strip coil has a plurality of divided segments, an expansion / contraction drum provided with a mechanism for expanding / contracting each segment in the radial direction, and a wrapping paper having a predetermined size supplied to the expansion / contraction drum. It is composed of a wrapping paper feeder that is wound around the outer circumference of the drum, and a drum moving machine that inserts the expansion / contraction drum into the inner circumference of the metal strip coil.
First, the expansion / contraction drum is reduced in diameter, and the wrapping paper is temporarily wound around the expansion / reduction drum, and the expansion / contraction drum is made to stand by near the entrance of the inner circumference of the metal strip coil, and the step of the inner circumference of the coil is detected by the device of the present invention.

る。There are the contact type sensor (vibrometer) and the gap type sensor as the step detecting device on the inner circumference of the coil, but in the case of the gap type sensor, the measurement accuracy is poor when the measurement distance (gap) is large, If the sensor is brought closer to the inner circumferential surface of the coil so that the gap becomes smaller in order to improve the measurement accuracy, there is a possibility that the sensor may hit the drooping steel strip and be damaged, and the accuracy is lowered. On the other hand, in the case of the contact type sensor, since the step is detected while guiding with a roller, it is resistant to the shake of the main body of the device, and the measurement gap can be made small by suppressing the sagging of the inner circumference, enabling highly accurate measurement. It has the characteristic of being For this reason, the present invention employs the contact type sensor in the step detecting device on the inner circumference of the coil.

圧シリンダーを用いている。In the apparatus of the present invention, a coil inner peripheral sag correcting jig is rotatably attached to the shaft end of the expansion / contraction drum shaft, and a plurality of divided pressing members are radially arranged at predetermined positions. The inner diameter of the coil is pushed up and fixed to the inner wall of the coil by increasing the diameter. A fluid pressure cylinder is used for the expansion / contraction mechanism of the split pressing member and the expansion / contraction mechanism of the step detection sensor.

に対して移動することがない。When the sagging of the inner circumferential end of the coil is corrected by the expansion of the split pressing member, the expansion drum shaft is rotated and the step detecting device integrally attached to the expansion drum shaft detects the step on the inner circumference of the coil. To do. At this time, since the coil inner circumference sag correcting jig is rotatably attached to the expansion / contraction drum shaft, it does not move with respect to the metal strip coil even if the step detecting device rotates.

押付けることができる。Since each of the divided pressing members of the coil inner circumference sag correction jig has a mechanism for expanding and contracting independently, even if the metal strip coil core and the expanding and contracting drum shaft are misaligned with each other, the dividing pressing members are separated from each other. Thus, the inner peripheral edge of the coil can be pressed uniformly against the inner peripheral wall of the coil.

内周面に傷が発生することもない。According to the apparatus of the present invention, the inner peripheral end of the coil can be pressed against the inner peripheral wall of the coil to detect a step without a gap, so that the pressing force of the roller of the step detecting device can be reduced. Therefore, the metal strip coil is not locally deformed and no indentation is left, and the metal band coil can be accurately detected. Further, each divided pressing member of the coil inner peripheral sag correction jig does not slide on the coil inner peripheral wall, and scratches do not occur on the coil inner peripheral surface by selecting the material.

ルの段差を精度よく検出することができる。When detecting the step of the metal strip coil 1 by the step detecting device having the above structure, the expansion / contraction drum 20 is made to stand by near the inner circumferential inlet of the metal strip coil 1, and at this position, the shaft end of the expansion / contraction drum shaft 2 is first. The air cylinder 3-3 of the coil inner peripheral sag correction jig 3 mounted on the coil is operated to expand the diameter of the split pressing member 3-4 to press and fix the inner peripheral end of the coil to the inner peripheral wall of the coil. Then, the air cylinder 4-2 of the contact type step detecting jig 4 is operated to press the roller 4-6 against the inner peripheral surface of the coil to rotate the expansion / contraction drum shaft 2. At this time, since the coil inner circumference sag correction jig 3 is rotatably supported by the expansion / contraction drum shaft 2, only the contact type step detection jig 4 rotates together with the expansion / reduction drum shaft 2 to correct the coil inner circumference sag correction. The tool 3 is held in a stationary state. Therefore, since the step detection on the inner circumference of the metal strip coil is performed in a state where there is no gap in the coil, the metal strip coil is not locally deformed by the pressing force of the roller and no indentation remains on the coil. Can be accurately detected.
