Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a device for winding a strip material and an intervening paper on an empty reel in an overlapping manner. The present invention relates to the structure of a device for winding around.

(b) Background of the technology Protection of strips wound around reels to facilitate storage and transportation, for example, surface protection of strips (hoop materials) made of soft metal, and processing of large numbers of strips using press processing means. As a product protection method for a strip in which a series of products are formed, it is generally practiced to wrap the strip to be protected on a reel by overlapping it with an interleaving paper. In such layered winding, especially when layered on a reel that is not provided with a locking means at the starting end of the winding, first wind the interleaving paper around the reel frame for about 2 to 3 turns, and then unwind the strip. It is necessary to wrap the strip by inserting an appropriate length between the intervening sheets from the starting end of the winding, and to prevent the intervening sheets from coming off during subsequent windings.

(c) Prior art and problems Conventionally, in the above-mentioned lap winding, after the winding start end is wound up, the winding is performed automatically according to the feed speed of the strip material, but the winding at the winding start end is carried out manually. Therefore, there was a strong desire for labor saving.

(d) Object of the invention The object of the invention is to provide mechanical means for eliminating the above-mentioned problems.

(e) Structure of the Invention The above object is to provide a rotatable loading platform on which a reel having a flange on one side of the reel is coaxially mounted, one end of which is mounted on a shaft that can move up and down, and can rotate coaxially with the loading platform. A clamp is attached to the other end of the arm to which the paper is fixed and can be opened and closed. A strip material and an intervening paper are configured such that, after being wound around a winding frame of a reel, an appropriate amount of the strip material is wound around the winding frame together with the intervening paper from the winding start end of the strip material. This is achieved by means of a winding device on a reel.

In the apparatus configured as described above, the arm 6 before the apparatus is driven is located at the position shown by the dashed line 6a in FIG. 1, that is, on the side of the stage 4. Therefore, the reel 1 is placed on the stage 4, and the clamp 3
2 and 33 clamp the vicinity of the winding ends of the interleaving paper 28 and the strip material 29, the air cylinder 16 is extended, the motor 22 is rotated by an appropriate angle in a predetermined direction, and the air cylinder 16 is contracted. As shown in the drawings and FIG. 2, the jaws 14 and 15 of the clamp 13 to be opened face each other with one circumferential wall of the winding frame 2 of the reel 1 interposed therebetween, and thereafter perform sequentially controlled operations as described below.

(a) The clamp 32 clamps the vicinity of the winding end of the interleaving paper 28 and moves forward. As a result, the winding end is inserted between the winding frame 2 and the jaw 14.

(b) The clamp 13 is closed, and the jaws 14 and 15 clamp the winding end and one peripheral wall of the winding frame 2.

(c) Clamp 32 opens and retreats.

(d) Rotate the motor 38 by an appropriate amount in a predetermined direction to move the carrier 34 to the vicinity of the metal fitting 37. As a result, the insert paper 28 pulled out from the reel 31 is wound around the reel 2 in a direction that intersects the extension line of the strip 29 at a certain inclination angle, as shown by a dashed line 28a in FIG. It becomes like this.

(g) After the shaft 47 is raised to the side of the insert paper 28a, it is reciprocated by an appropriate amount toward the insert paper 28a. As a result, the reciprocating motion causes the reel 31 to
The insert paper 28a pulled out from the frame 2 becomes slack, and the insert paper 28 wound around the winding frame 2 and the jaw 14 also becomes loose, causing the clamp 1 to loosen.
3 can be opened and removed.

(H) After opening the clamp 13, operate the air cylinder 16 to lift the tip side of the arm 6 to which the motor 6 is attached. As a result, clamp 1

(v) The air cylinder 16 is operated in the reverse direction, and the clamp 13 is lowered to the position of the winding frame 2. As a result, the jaws 14 of the clamp 13 are located outside the insert paper 28a, and the jaws 15 are located inside the winding frame 2.

(l) The clamp 33 clamps the vicinity of the wrapped end of the strip 29 and moves forward. As a result, the wound end of the strip is inserted into the wedge-shaped gap between the already wound interleaving paper 28 and the inclined intervening paper 28a.

(w) The clamp 13 is closed and clamps the wrapped end of the strip to the intervening paper. At this time, one peripheral wall of the winding frame 2 is also clamped together.

(W) Rotate the motor 7 by an appropriate angle in the same direction as the above-mentioned rotation and stop it, for example, when the arm 12
is rotated 180 degrees and stopped.
As a result, the strip 29 is wrapped around the winding frame 2 along with the interleaving paper 28 by an appropriate length from the winding end,
It will no longer come off due to the tension that accompanies automatic winding.

(f) Clamp 13 opens and air cylinder 16
