From step 8, adhesive 37 is sprayed onto the upper surface of the tip of the thin iron plate 36 over its entire width.

Once the adhesive 37 has been sprayed over the entire width of the upper surface of the tip of the thin iron plate 36, the moving cart 8 is moved until the adhesive spraying means 17 is located directly above the rear end of the thin iron plate 36, which is being conveyed. The moving cart is moved backward and moved forward again in the same manner as described above, and the adhesive spraying means 17 is activated.
As shown in FIG. 4, adhesive 37 is sprayed over the entire width of the upper surface of the rear end of the thin iron plate 36.

In this state, by moving the moving cart 8 in the conveying direction, the vicinity of the tip of the thin iron plate 36 that has been attracted by the suction means 13 is transferred from the end of the conveying device 5 to the coil supporting device 1 as shown in FIG. It can be conveyed to the outer drive roller 3b via between the pair of front and rear drive rollers 3a and 3b.

The movable cart 8 returns to its original home position in a state in which each electromagnet 15 of the thin iron plate adsorption means 13 is demagnetized and the adsorption means 13 is raised and returned together with the adhesive spraying means 17 by the cylinder/piston unit 16. Move the ends.

Once the above preparatory work is completed, the coil 2 is transferred onto the pair of drive rollers 3a, 3b in the coil support device 1 by an appropriate transfer means as shown in FIG. The tip of the thin iron plate 36 on which the agent 37 has been sprayed is sandwiched between the drive roller 3b and the coil 2, and the tip is adhered to the outer peripheral surface of the coil 2 by the adhesive 37. In such a state, the drive roller 3
a, 3b are rotated by the driving means 4, and the coil 2
The direction in which the thin iron plate 36 is wound (in the direction of the arrow in Fig. 6)
By rotating the thin iron plate 36 on its own axis, the thin iron plate 36 whose tip end is bonded to the coil 2 is wound by the coil 2 and wound on the outer peripheral surface of the coil 2. When the rear end of the thin iron plate 36 passes over the driving roller 3a, the rear end of the thin iron plate 36 is attached to the tip of the thin iron plate 36 on the coil 2 by the adhesive 37 sprayed on the upper surface. (end of the winding start).

The electromagnet 23 of the movement resistance adding means 21 for the thin iron plate is energized when the tip of the thin iron plate 36 is stretched between the pair of drive rollers 3a and 3b as shown in FIG. By adsorbing the iron plate 36 with an appropriate force, when the coil 2 winds up the thin iron plate 36, an appropriate tension is applied to the thin iron plate 36, and the thin iron plate 3 is attached to the surface of the coil 2.
6 can be wound up in close contact.

The order in which the adhesive is sprayed onto the top surface of both longitudinal ends of the thin iron plate 36 is not limited to the above embodiment. Further, the centering guide 9 and the movement resistance adding means 21 are not essential and can be omitted.

The device for wrapping thin plates, etc. around a cylindrical body of the present invention can be implemented as described above, and in a packaging line for rolled iron plate coils, a protective thin iron plate is wound around the outer peripheral surface of the coil. The cylindrical body support device is equipped with at least a pair of driving rollers that rotatably support the cylindrical body using its outer peripheral surface; It consists of a conveying device that conveys a wrapping material such as a thin plate onto a cylindrical body support device, and the conveying device is provided with a movable cart that can move in the conveying direction, and this moving truck has a A means for moving transversely above the wrapping material to apply an adhesive or the like to a predetermined location on the upper surface of the wrapping material (not limited to the adhesive spraying means 17 of the embodiment; for example, a means for applying double-sided adhesive tape) )
and a winding material holding means (not limited to the suction means 13 of the embodiment) that can be raised and lowered for transporting the leading end of the winding material from the end of the conveyance path to a position beyond the pair of drive rollers (not limited to the suction means 13 of the embodiment, for example, Depending on the material of the attachment material, vacuum suction means etc. can also be used).

According to the winding device of the present invention, simply by placing a cylindrical body between a pair of driving rollers and rotating the cylindrical body on its own axis by the driving rollers, the material can be securely wrapped around the cylindrical body. It can be wrapped around and fixed with adhesive or the like. Therefore, it is not only possible to easily wrap the wrapping material even on a cylindrical body that does not have a central hole that can be used for rotatably clamping and lifting, but also because the cylindrical body is heavy. Even if this happens, it only needs to be supported and rotated between a pair of drive rollers, so the device does not have to be as large as in the past, and it can be implemented at a relatively low cost. . Furthermore, even if the outer diameter of the cylindrical body changes slightly, as long as it can be rotatably supported between a pair of drive rollers, the desired winding can be achieved without changing the supply position of the winding material. The attaching action can be performed reliably.
