Description

[Detailed explanation of the idea] The present invention relates to a waste winding device for a winder.

For example, when winding a wire rod that has undergone continuous annealing or continuous plating onto a winding bobbin, after the operation has started, the wire rod that will not be used as a manufactured product is wound separately during the time when the characteristics are stabilized. A winding bobbin with winding reels arranged side by side is used.

FIG. 1 shows such a winding bobbin 1, in which a traverser 2 is a waste winding reel 1 in a housing in which the wire rod 3 is a predetermined non-defective product.
The wire rod 3 is guided to the reel 1b, and when the wire rod 3 is found to be good, the wire rod 3 starts moving in the direction of arrow X according to a command and is guided onto the main reel 1b.

However, in this type of waste winding device, even if the traverser 2 moves onto the main reel 1b, the wire 3 is blocked by the intermediate 7 langes 1c and does not immediately move onto the main reel 1b.

For this reason, the wire 3 has a considerable angle at the intermediate 7 flange 1c.
and the main reel 1b, but this part 3
When the traverser 2 returns, the wire a is pressed by the upper wire and breaks, making it impossible to take out the wire.

Further, if the wire does not break, there is a problem that the wire cannot be wound at the middle 7 langes 1C of the main reel 1b, resulting in poor winding conditions.

In order to solve these difficulties, in addition to the traverser,
A waste winding device for a winder has been proposed that uses a guide roller equipped with a wire detachment mechanism that guides the wire to a waste winding reel.

FIG. 2 shows an example in which a combination roll consisting of a fixed roll 4a and a movable roll 4b is used as the guide roll 4.

Note that in the drawings from FIG. 2 onwards, parts common to those in FIG. 1 are designated by the same reference numerals.

In this waste winding device, at the time of starting, the traverser 2 is fixed to the intermediate flanone 1c, and the guide roll 4 moves the waste winding reel of the take-up bobbin 1 with the national roll 4a and the movable roll 4b abutting their end surfaces. 1a.

Wire rods that do not become products at the beginning of production are Traverser 2,
The waste winding reel 1a of the winding bobbin 1 passes through the guide roll 4
is wound around.

Next, when the wire rod 3 is in a good condition to become a product, the movable roll 4b moves in the direction of arrow A, and then the traverser 2 starts moving in the direction of arrow B, and the wire rod 3 is wound onto the main winding drum 1b. Ru.

According to the above-mentioned waste winding device, since the wire 3 is guided astride the intermediate flange 1c from the beginning, the wire 3 that has left the guide roll 4 is immediately mounted on the intermediate flange 1C, and the wire rod 3 is guided from the side of the intermediate flange 1C. It will be wound onto the reel 1b.

However, since this waste winding device uses a two-split combination roll as the guide roll 4, when winding a fine wire, there is a drawback that the fine wire gets pinched at the butt part of the rolls and often breaks. Ta.

The present invention was made to eliminate such conventional drawbacks, and includes a single-flange guide roll that guides the wire running through the guide of the traverser to the waste winding reel, and a single-flange guide roll that separates the wire from the single-flange guide roll. It is an object of the present invention to provide a waste winding device for a winder that does not have the above-mentioned drawbacks and is equipped with a wire rod detachment mechanism.

The details of the embodiment shown in FIGS. 3 and 4 will be explained below.

The waste winding device of the present invention includes a take-up bobbin 1 on which waste winding reels 1a are arranged side by side, a traverser 2 whose moving direction is parallel to the rotation axis of the take-up bobbin 1, a driver, and a guide for the traverser 2. This device is similar to the conventional waste winding device shown in FIG. 2 in that it includes a guide roll and a wire detachment mechanism for guiding the wire 3 traveling through the waste winding reel 1a.

However, the present invention is characterized in that a single-flange guide roll 5 is used as the guide roll.

The guide roll 5 with one flange is arranged with the flange 5a side facing the main roll 1b, and the peripheral edge of the guide cylinder 5b on the side without the flange 5a is such that the wire can be easily detached and the wire rod can be easily detached. A curved surface R is formed to prevent the wire from being damaged.

As shown in FIGS. 5 and 6, this one-sided guide roll 5 has a rotating shaft 6 supported by a support 7 perpendicular thereto, and the base of the support 7 is provided to protrude from a support member 8. It is fixed to a cylindrical bearing 10 which is rotatably fitted onto a rotary shaft 9.

An arm 11 protruding from the outer periphery of the cylindrical bearing 10 is perpendicular to the column 7, and this arm 11 is connected to an operating rod 12a of an air cylinder 12 whose base is pivotally connected to the support member 8.
It is pivotally connected via b.

In the above-described configuration, the guide roll 5 with a single flange faces the winding bobbin 1 with the flange 5a facing the main reel 1b when the operating rod 12a of the air cylinder 12 is contracted.
When the operating rod 12a is extended, it rotates about the rotating shaft 9 such that the side without the collar 5a faces the take-up bobbin 1.

The waste winding device having the above configuration is used as follows.

1. When winding the wire rod, the traverser 2 is fixed (supported) near the intermediate flange of the main reel 1b, and the operating rod 12a of the air cylinder 12 is contracted to move the guide roll 5 on one side of the flange. With the end face perpendicular to the rotational axis of the winding bobbin 1, the wire rod 3 is passed to the traverser 2, the one-flange guide roll 5 button, and the waste winding rule 1a as shown in FIGS. 3 and 4. .

When the winding bobbin 1 is rotated in this state, the wire rod 3 that is not the original product is wound onto the waste winding reel 1a.

When the wire 3 is found to be of good quality, when the operating rod 12a of the air cylinder 12 is extended, the guide roll 5 with one flange rotates around the rotating shaft 9 and faces the side without the flange.

Here, since the winding tension is acting on the wire rod 3, it separates from the guide cylinder 5b of the guide roll 5, and the wire rod 3 straddles the intermediate flange 1c and is wound around the intermediate flange of the main reel 1b. It turns out.

Next, when the traverser 2 is reciprocated within the width of the main reel 1b, the wire rod 3 is sequentially wound onto the main reel 1b.

As described above, according to the present invention, it is possible to wind the wire from the middle 7 lunges of one knot of the main winding, and in addition, the wire is guided to the waste winding reel by a guide roll with one flange. Because of this, there is no risk of the wire being pinched and breaking unlike in combination rolls.

In addition, in the above embodiment, an example was explained in which a mechanism for rotating the guide roll of one flange was used as a mechanism for separating the wire from the guide roll of one flange, but the present invention is limited to such an embodiment. Instead, for example, a lever or the like may be used to push the wire passed over the guide roll with one flange to the side without the flange.
