The second transfer device 30 moves between the storage box 6 and the end mark preventing material inserting device 10, and absorbs and lifts up the end mark preventing material 5 contained in the loading box 6, and ends in the state. By moving to the mark prevention material insertion apparatus 10, the end mark prevention material 5 can be seated on the end mark prevention material insertion plate 11.

More specifically, the second transfer device 30 may include third adsorption means 32a and 32b and lifting means 34.

The third adsorption means 32a and 32b are for adsorption-fixing one surface of the end mark preventing material 5, and the third adsorption means 32a and 32b are also similar to the first adsorption means 12, the front end portion. It can be provided with a flexible material, such as rubber | gum, and a vacuum tube.

The lifting means 34 is coupled to the third adsorption means 32a, 32b at one end, and is fixed to the end mark prevention material 5 through the third adsorption means 32a, 32b by using a pneumatic or hydraulic cylinder. ) To lift or lower.

Thus, when using the said 3rd adsorption means 32a and 32b and the lifting means 34, the end mark prevention material 5 contained in the loading box 6 is moved to the end mark prevention material insertion apparatus 10, a control part Through the lifting means 34 can be controlled to repeatedly lift movement.

When raising, it is preferable that the lifting means 34 shakes the end mark prevention material 5 by repeating lifting movement at least 1 time or more.

As shown in FIG. 2, when a plurality of end mark preventing materials 5 having at least one magnet pad 5b on one surface are stacked in the stacking box 6, different end mark preventing materials 5 may be formed. The attractive force is generated by the magnetic force of the magnet pad 5b, and they stick together. Accordingly, in order to prevent the two or more end mark preventing materials 5 from being seated on the end mark preventing material inserting plate 11, the lifting means 34 repeatedly moves up and down, whereby the third suction means 32a is used. , It is preferable to drop the end mark preventing material 5 which is not directly adsorbed to 32b).

At this time, the second transfer device 30 is provided with at least two or more third adsorption means (32a, 32b), each preferably disposed in a position symmetrical with each other. That is, if the plurality of third adsorption means 32a, 32b provides adsorption force at a position symmetrical with respect to the center of the adsorbed end mark prevention material 5, the adsorption force is solidified and the end mark prevention material ( 5) will be level and stable.

Moreover, it is preferable to further provide the cylinder 33a, 33b which couple | bonded the 3rd adsorption means 32a, 32b to one end.

And, if it controls the individual lifting movement with respect to the third adsorption means (32a, 32b) through the control unit, when a large number of end mark prevention material (5) having a magnetic pad (5b) is loaded, by only one side lifting movement The rotors can be more effective, allowing them to fall apart easily.

As an example, when the third adsorption means 32a, 32b are lifted up by the adsorption fixation to transfer the end mark prevention material 5 to the end mark prevention material insertion device 10, it is directly by the magnetic pad 5a. Adjacent end mark preventing materials 5 which are not suction fixed may be caught up by the attraction force. In order to effectively shake it, if only one cylinder 33a moves up and down, as shown in FIG. 2, the end mark preventing material 5 provided with a plurality of magnet pads 5b is separated from one side, and the end mark The self weight of the barrier material 5 makes it easier to separate it from the other end mark barrier material 5.

At this time, if only a part of the cylinder 33a moves up and down, it is preferable that the part is a cylinder combined with the 3rd adsorption means close to the sponge part 5a of the end mark prevention material 5. As shown in FIG. This is because the end mark preventing material 5 is heavier in its direction by the sponge portion 5a.

On the other hand, the control unit (not shown) is a means for controlling the overall operation of the end mark preventing material inserting apparatus 100 of the coil according to the present invention, the end mark preventing material 5 loaded in the stacking box 6 to prevent the end mark It transfers to the reinsertion apparatus 10, and controls to insert the steel plate strip front-end | tip part in the end mark prevention material 5.

On the other hand, the stacking box 6 is a container for loading the end mark preventing material (5), may be one, but preferably includes two or more.

That is, since the steel sheet strip 1 may have different widths, such as 1000 mm, 1200 mm, 1400 mm, and 1600 mm, according to the specification, an end mark prevention material (e.g., corresponding to each time the width of the steel sheet strip 1 to be wound) changes ( If you change the loading tray containing 5), it can be cumbersome for the worker.

Therefore, at least two or more loading boxes 6 for storing and storing the end mark preventing material 5, each preferably formed in different lengths to meet various specifications of the steel sheet strip 1, the control unit is It is preferable that the second mark device 30 transfers the end mark prevention material 5 contained therein to the end mark prevention material inserting device 10 with respect to one stacking box 5 selected according to the external input.

More specifically, the end mark prevention material automatic insertion device 100 of the coil according to the present invention further includes a rotary motor 41 and a rotary arm 42, so that any of a number of stacks 6 of various sizes 6 You can choose one.
