Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is applied to metal coil wrapping operations, in which the outer periphery of the coil and the folded end of the wrapping paper on the end face are inserted into the inner circumferential hole of the coil and fixed. The present invention relates to a circumferential tape application device.

(Prior Art) Packaging of metal coils is indispensable for transportation and rust prevention, and automation of devices is being attempted to further save labor. For metal coils, packaging for the outer periphery of the coil and wrapping for the inner periphery of the coil are performed separately in the process. For wrapping the inner circumference of the coil, insert a cylindrical wrapping paper (inner circumferential paper) with the same diameter as the inner diameter of the coil into the coil hole, but for wrapping the outer circumference and end face, add extra allowance for the end face of the coil from the inside of the coil. Wrap a wide wrapping paper around the outer circumference of the coil, fold the protruding parts of both end faces of the coil to form pleats on the end faces of the coil, and insert the folded ends into the holes on the inner circumference of the coil to fix them. is normal.

As a fixing method, there is a method of pasting tape in the circumferential direction on the inner circumferential surface of the coil at nine parts where the inner circumferential paper and the folded end overlap, but conventionally this method had to be done mainly by manual labor. Further, Japanese Patent Application Laid-Open No. 59-124236 proposes a cylindrical hole edge folding and tape pasting device that is compatible with several types of hole diameters, which will be explained below with reference to FIG. 6.

In the figure, a small-diameter tube 2, a medium-diameter tube 6, and a large-diameter fold tube 4 prepared in advance are selected and inserted into the coil hole of the cylinder.

A pivot shaft 10 is provided, and the pivot shaft is fully rotated to cause the pasting call 16 to slightly protrude from a specific window. Tape supply source 5
The leading end of the tape supplied from the tape is pasted on the inner peripheral surface of the coil through the entire hollow support shaft 1 to the overlapped portion of the inner peripheral paper, the outer periphery, and the folded end of the end wrapping paper.

Incidentally, in recent years, as the unit weight of coils has increased and the width of coils has increased, automation of coil packing operations has been desired.

(Problems to be Solved by the Invention) The present invention provides adhesive tape in the circumferential direction of the inner periphery of the coil at the overlapping portion of the inner periphery paper for wrapping and the folded end of the wrapping paper on the outer periphery and end face. The present invention provides a compact inner circumferential surface tape application device for fixing the folded end of the wrapping paper to the inner circumference of the coil by pasting the folded end of the wrapping paper.

(Means for Solving the Problems) The present invention comprises a large gear 8 directly connected to a fluid pressure cylinder serving as a rotational drive source for selecting the inner diameter of a metal coil, a plurality of small floats 9 meshing with the large gear 8, and a small gear 8. A rack 10 that meshes with another small gear 9 coaxial with 9 and a hydraulic cylinder 12 that gives a stroke to the rack 10 are provided.

The present invention has been described above mainly with respect to an example in which the present invention is applied to the device main body, but of course the present invention is not limited to this, and can be broadly applied to a pleat forming device for coil wrapping paper, and as long as it does not deviate from its purpose. It is within the scope of the present invention.

(Effects of the Invention) In the present invention, the coil inner surface pressing mechanism 50 and the tape pasting mechanism 70 are integrated, and are selectively adapted to the inner diameter of the coil by the cylinders 5 and 22. Since the paper finishing plate 7 has a short stroke due to the cylinder 5, there is great flexibility with respect to slight variations in the inner diameter of the coil, types of wrapping paper, etc.

The wrinkles of the wrapping paper on the end face of the coil can be removed by setting the outer part of the lining plate to be thicker than the inner diameter of the coil and pushing it into the coil hole. Furthermore, the equipment is relatively compact and reliable.
