Abstract

PROBLEM TO BE SOLVED: To prevent the drop of a winding package on a floor surface by providing a deceleration means which decelerates the winding package which runs on a package tray of an automatic winder. SOLUTION: When a winding package 4 which winds a predetermined amount of thread in a winding part 5 drops on a bucket 3 in a horizontal condition, a detector detects its drop and transmits a signal to a bucket drive device. Since the bucket drive device tilts the bucket 3 downward toward a take-out part 7, the winding package 4 slides and runs on a bucket 4. Then, the winding package 4 which runs along an inclined face collides against a deceleration plate 2 earlier than the time when the bucket 3 reaches the maximum inclination angle and stops temporarily. After that, the bucket 3 is tilted further, and the winding package 4 continues to run at a low speed in a condition in which an upper section comes into contact with the deceleration plate 2 and drops on a package tray 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an automatic winder which is used in a rewinding process of sewing machine threads and the like and which winds a thread from a yarn supplying package to a winding package.

[0002]

2. Description of the Related Art Conventionally, an automatic winder for winding a yarn from a yarn supplying package to a winding package has been used in the rewinding process of sewing machine yarn and the like. FIG. 2 is a perspective view showing a general automatic winder. As shown in FIG. 2, the automatic winder has an inlet portion (9) and a winding portion (5) along the traveling path of the yarn (6). And the outlet portion (1) are sequentially arranged.

The inlet portion (9) is provided with a stand pipe (1
0) Supply creel (1) fixed with an arm
1), a balloon prevention guide (12) and a yarn guide (13), wherein the yarn supplying package (14) is mounted on the supply creel (11) and wound around the yarn supplying package (14). The wound yarn (6) is supplied to the winding section (5) on the downstream side.

The winding section (5) comprises a bobbin magazine section (15) shown in FIG. 2, a pair of winding shafts (16), a traverse yarn guide (17) and a bobbin (18) shown in FIG. An empty bobbin (18) supplied to the winding position (19) from the bobbin magazine section (15) is grasped from both ends by a pair of winding shafts (16) and rotated. The yarn (6) supplied from the inlet (9) is wound on the bobbin (18).

The outlet section (1) comprises a bucket (3) and a package tray (8) having a take-out section (7) on the front side of the machine base, and is wound in an upstream winding section (5). Take-up package taken up (4)
Are integrated. Here, the bucket (3) is provided below the winding position (19), and has one end rotatably supported so as to incline downward from the horizontal state toward the take-out portion (7). . The package tray (8) is composed of several pipes, and is fixedly installed below the bucket (3) in a state of being inclined downward toward the take-out portion (7), and the winding package (4).
Is to form a traveling path of.

The above is the configuration of the apparatus. Next, the operation will be described. The yarn (6) unwound from the yarn supplying package (14) mounted on the supply creel (11) shown in FIG. First, after the yarn (6) formed by the balloon prevention guide (12) and the yarn guide (13) is supplied to the winding section (5) along the traveling path, the traverse yarn guide (17) shown in FIG. It passes through the thread communication hole (20) provided in the. At this time, the traverse yarn guide (17) is connected to a cam (not shown) that rotates in conjunction with the winding shaft (16), and the cam causes the traverse yarn guide (17) to rotate along the axis of the winding shaft (16). The yarn (6) is wound around the bobbin (18) along the outer periphery of the bobbin (18) in a frustoconical shape as a winding package (4) according to the movement of the traverse yarn guide (17). To be

Next, a predetermined amount of thread (6) is threaded onto the bobbin (1).
When wound on 8), the winding shaft (16) releases the bobbin (18) so that the winding package (4) falls onto the bucket (3) and further the bucket (3). ) Is inclined downward toward the take-out portion (7), so that the winding package (4) falls on the package tray (8). After that, the winding package (4) travels on the package tray (8) and is accumulated in the take-out section (7), and the accumulated winding package (4) is manually taken out from the take-out section (7). Will be transferred to the downstream process.

[0008]

However, in the case of the above-mentioned automatic winder, the winding package runs vigorously on the package tray and in some cases falls onto the floor surface, so that the winding package becomes dirty. Had a problem. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an automatic winder capable of preventing the winding package from falling onto the floor surface.

[0009]

The above object is to wind a yarn from a yarn supplying package to a winding package by sequentially arranging an inlet portion, a winding portion and an outlet portion along a traveling path of the yarn. In the automatic winder, in which the take-up package travels on the inclined package tray and is taken out at the exit portion, the automatic winder is provided with deceleration means for decelerating the take-up package traveling on the package tray. It In the present invention, since the speed reducing means is provided at the outlet portion, the speed reducing means comes into contact with the traveling winding package to decelerate the winding package, and the winding package is prevented from falling from the outlet portion to the floor surface. Can be prevented.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of an embodiment of the present invention will be described.
Description will be given based on the attached drawings. FIG. 1 is an explanatory view of a cross section as seen from the side of an outlet portion (1) of an automatic winder according to an embodiment of the present invention. As shown in the figure, this automatic winder is the above-mentioned conventional automatic winder with a reduction plate (2) added, and the other configurations are the same as those of the conventional automatic winder. The same reference numerals are given and detailed description thereof is omitted.

The speed reduction plate (2) is made of a stainless steel flat plate, and at the outlet portion (1) shown in FIG. 1, the upper portion of the winding package (4) running on the slope of the bucket (3) while the bucket (3) is tilting. It is provided at a position where the upper part of the winding package (4) comes into non-contact with each other when the bucket (3) comes into contact with the steepest gradient.

Next, the operation of the outlet part (1) of the automatic winder will be described. A winding package (4) in which a predetermined amount of yarn (6) is wound in the winding part (5).
When it falls on the bucket (3) kept in a horizontal state, a detection device (not shown) detects the fall and transmits this as a detection signal to a bucket drive device (not shown). Upon receipt of this detection signal, the bucket drive device is a bucket (3)
To incline downward toward the take-out part (7),
The winding package (4) is allowed to slide on the bucket (3).

Then, the winding package (4) running along the inclined surface is made to collide with the reduction plate (2) and stop once before the bucket (3) reaches the maximum inclination angle. Become. After that, the bucket (3) further tilts, and at the same time, the winding package (4) continues to run at a low speed with the upper part in contact with the reduction plate (2), and falls onto the package tray (8). At this time, the winding package (4) is sufficiently decelerated by the reduction plate (2), so that it does not fall from the package tray (8) to the floor surface.

In the above embodiment, the speed reducer is made of a flat plate of stainless steel, but the form and material are not limited as long as the traveling winding package can be decelerated.

[0015]

As described above, according to the automatic winder of the present invention, the speed of the winding package traveling on the package tray can be suppressed by the speed reducing means, and it is possible to prevent the winding package from dropping from the package tray. The dust on the surface does not adhere, and the effect of improving the quality is achieved. Further, the present invention has an effect that it can be realized at low cost because of its simple structure.
