Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a doffing device for a swing arm type winder.

[0002]

2. Description of the Related Art In recent years, in a method of producing synthetic fiber, a direct drawing and winding method of forming a product in one step from spinning has been widely adopted and widely used. There are many ways to make it into a product.

[0003] In particular, among the unwinding yarn winding machines, a swing arm type winding machine is dominant and many facilities are still in operation at present.

FIG. 6 is a side view of a conventionally known winding machine for winding an undrawn yarn that has been melt-spun. To doff the undrawn yarn wound in the drum shape by the swing arm type winder, as shown in FIG.
Is wound around a roll (not shown), or the running yarn is sucked by the suction gun 17 to cut off the supply of the yarn to the winding machine, and as shown in FIG. ,
The take-up drum 4 is released from the drive roll 3, the brake lever is operated to stop the rotating take-up drum 4 ', and the holder holding the take-up drum 4' is released by operating the detachment lever. Then, pull the drum out of the holder by hand, insert it into the peg (not shown) of the drum truck on which the drum product is loaded, and then insert and fix the empty drum into the holder to wind the undrawn yarn. A series of operations is completed by setting the arm to the side 3 and bringing the empty drum into contact with the drive roll 3 and restarting the threading.

During the doffing operation, the drum at the doff position A is located at a low position of 30 cm to 40 cm from the floor, and the operator takes a posture in which the waist is greatly bent. Depending on the scale per machine, if there are many, this series of operations is performed about 20 to 30 times.

In recent years, as shown in FIG. 7, large packages have been promoted for winding undrawn yarns, and winding machines have been modified. In the past, a single wound drum weighed about 5 to 6 kilograms.
Therefore, it becomes heavy from 9 kg to 12 kg, and the burden on the operator is large to repeat the doffing work manually while bending the waist greatly. In addition, the distance E between the take-up drum surface and the floor surface may be as small as about 5 cm due to the fact that the take-up drum surface is close to the floor surface. . In addition, as shown in FIG. 8, the winding machine 7 of the adjacent weight is in proximity, and the removed winding drum is often applied to the winding stand 7 of the adjacent weight, thereby generating a large amount of dust from the winding drum. Became. Further, in extreme cases, the drum may be hit against the drum being wound by the adjacent weight, which requires careful work and delays the promotion of large packaging.

[0007]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the problem of the conventional doffing operation, that is, to provide a doffing device for safely extracting a take-up drum near a floor. It is assumed that.

[0008]

In order to solve this problem, a doffing apparatus according to the present invention mainly has the following configuration. That is, a rail provided on the floor surface in parallel with the take-up shaft of the winder, a bearing slidably mounted on the rail, and a bearing whose tip is inclined away from the winder via a pin joint. A doffing device for a swing arm type winder, comprising: a support leg having a support mounted on the vehicle and a wheel movable in parallel with the rail, and supporting the support, and a peg provided on the support so as to be able to move up and down. It is.

Further, in the doffing device of the present invention, (1) pegs are provided on both right and left sides of the column, (2)
It is a preferable embodiment that the above-mentioned columns are attached to the rail via a bearing and a pin joint.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A doffing device in a swing arm type winder according to the present invention will be described below with reference to FIGS.

FIG. 1 shows a doffing device for a swing arm type winder according to the present invention, which includes a peg 8 (a peg 21 is present on the back side) for receiving a drum 5 wound and wound into a large package, and a lifting device 9. It is a side view showing the whole of an example of a device.

FIG. 2 shows the doffing device 14 with the rail 1 next to the large packaged drum 5 to be doffed.
FIG. 4 is a front view showing a state in which the robot moves on the second and waits.

As shown in FIG. 3, the yarn running on the drum to be doffed via the roll 23 is absorbed by a suction gun 17 and the running direction of the yarn 16 is changed.
The arm 2 shown in FIG. 2 is lowered to the front, the brake lever 18 is operated to stop the winding drum, and the doffing device 14 is inserted into the bobbin 19 of the drum 5 as shown in FIG. Holder (not shown)
Is released and the drum is handed over to the peg 21 attached to the doffing device 14 by hand. Thereafter, the select switch 20 shown in FIG. 4 is operated, and the peg 21 (the peg 8 is present on the back side) is raised to the upper limit position 21 ′ (the peg 8 ′ is present on the back side) by the lifting cylinder 9 and stopped. FIG.
Is preferably slightly lower than the waist when the worker is standing, and is 75 cm in this embodiment. The drum raised to the height C is manually extracted from the peg 21 '(or peg 8') and loaded on a drum car.

In this manner, the doffing device 14 is sequentially moved to the side of the drum to be doffed. In the conventional winding machine, as shown in FIG. 2, the winding drums 5, 5 'are arranged so as to face each other. Therefore, the doffing device 14 is also provided on both sides of the pegs 8 and 21 and the column 10 as shown in FIG. When doffing the left drum 5 shown in FIG. 2, the doffing device is moved to the right side of the drum, and when the right drum 5 'is doffed, the doffing device is moved to the left side of the drum to perform the doffing operation.

[0015]

As shown in FIG. 1, at the time of doffing, the distance B between the take-up shaft of the take-up drum attached to the swing arm 2 '(indicated by a dotted line) and the rail 12 which has been tilted forward and the rail 12 is set for all the drums. The rails are installed at the same height so that they are at the same distance. Therefore, even if the level of the floor 6 is different, the support 1 supported by the wheels 11
0 is peg 8 at almost the same level as the drum doff position,
21 can be arranged, and the doff work can be performed without any trouble.

The base of the support 10 of the doffing device is supported by a bearing 22 and a rail 12 via a pin joint 13, and the floor 11 has a slope F by wheels 11 supporting the support 10, and the pegs 8, It is preferable to secure a distance D between the take-up drum 5 ′ of the adjacent weight and the doffed drum 5 when the ascent is raised. In the embodiment, this distance D is a short distance of about 5 cm. In this way, when the take-up drum is doffed, it is possible to effectively prevent the take-up drum 5 'of the adjacent weight from contacting or hitting.

[0017]

According to the present invention, the drum to be doffed can be kept away from the floor, the adjacent frame, and the drum being wound, and the drum can be raised to a working height where the worker can easily apply power. Work that could not be accepted can be safely provided.
