Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-cup winder for winding a plurality of continuously running yarns on a plurality of bobbins in a synthetic fiber production process.

[0002]

2. Description of the Related Art In recent years, in a synthetic fiber manufacturing process, a multi-cup winder in which a plurality of yarns are wound by a single winding machine has been widely used in order to improve productivity. In such a conventional multi-cup winder, a plurality of rolled-up packages are collectively pushed to a doffing position and then doffed all at once in an automatic doffing device, or one by one by manual work. It was fried.

However, in order to improve the productivity, the winding package has been made into a large package, the weight of the package has increased, reliance on manual work has become a problem from the viewpoint of occupational safety, and the labor cost has also risen. . From such a background, an automatic doffing device has come to be adopted when doffing a package rolled up.

As described above, in a package wound with a multi-cup winder, the weight of the package to be stored becomes very heavy due to the influence of the large package and the multi-cup. For this reason, it is necessary to increase the rigidity of the bobbin holder of the automatic doffing device, and since the bobbin holder has a high rigidity, special consideration needs to be given to the material and design of the bobbin holder, and the equipment cost increases.

Further, since the packages to be doffed are arranged in series, if the packages are to be accommodated in the automatic doffing device at once, the machine stand length of the automatic doffing device becomes long in the doffing direction. . If you try to shorten the machine length of this automatic doffing device that has become longer in the doffing direction, you can transfer the doffed package to another loading device in preparation for doffing the next package. The mechanism becomes complicated and large.

Further, when the equipment layout is such that the winder groups face each other, the distance between the winders facing each other is predetermined, and therefore the machine stand size of the automatic doffing device is also subject to this restriction. To be This constraint is most severe when two doffing machines need to rub against each other when simultaneously doffing these opposing winder groups. Further, in order to effectively use the installation space of the equipment even when there is a margin in the layout, it is not a good idea to lengthen the machine stand size of the automatic doffing device.

Therefore, it is necessary to design and manufacture an automatic doffing device so that the machine size in the doffing direction of the automatic doffing device does not necessarily become long.
This is a very complicated mechanism, which reduces the reliability of the device and makes maintenance complicated. Also, of course, the cost of manufacturing an automatic doffing device is high.

[0008]

[Problems to be Solved by the Invention] As described above,
The present invention is intended to solve the following problems by providing a winder having a mechanism that is not present in conventional multi-cup winders.

That is, it is necessary to eliminate manual work in the doffing work of a multi-cup winder, and to prevent the machine size in the doffing direction from becoming large and complicated in the case of doffing by an automatic doffing device.

[0010]

[Means for Solving the Problems] As means for solving such problems, a pusher for pushing a wound package to a doffing position of the package is provided, and the package pushed by the pusher is prevented from falling. In a multi-cup winder having a supporting means that moves in conjunction with the pusher while supporting the formed bobbin, at the stage when doffing of the extruded package is completed, the next package that has not been doffed yet In order to be able to push the doffing position to the doffing position, the lowering means for lowering the supporting means that does not need to support the bobbin forming the package, and the supporting means for the package after the doffing have been lowered, Equipped with push-out means for sequentially pushing packages that have not yet been fried to the doffing position Multi cup winder is provided, characterized in that.

[0011]

By using the above means, the problems of the present invention can be solved as follows. That is, the most important point of the present invention is to perform the doffing operation in multiple stages. The advantage of performing the doffing of this package in multiple stages is that it is not necessary to arrange all the packages that have been wound up in series, and the number of packages arranged in series at one time can be divided. Therefore, the length of the doffing package in the doffing direction can be shortened, and when performing doffing work using the automatic doffing device,
The doffing direction dimension of the automatic doffing device can be shortened.

Here, in order to give the winder the function described above, the present invention employs the following means.
That is, since the doffing is divided into multiple stages, it is necessary to have a means for pushing the packages to the doffing position at each doffing stage. This is to push the packages that have not been fried to the doffing position one by one. It becomes possible by the pushing means.

The following means are required as conditions for enabling the sequential extrusion of the package to the doffing position. In other words, when the doffing of the extruded package is completed, the next package that has not been doffed can be pushed to the doffing position. It is to install the descending means. In this way, the supporting means for the package after the doffing is completed and the supporting means for the package that is pushed out to the doffing position of the package next can move without interfering with each other. .

Further, it is preferable that a supporting plate for pressing the package against the end of the package and pushing the package out of the bobbin holder of the winder is provided in the supporting means of the package.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings.

FIG. 1 is an explanatory view showing an embodiment of a doffing operation by a multi-cup winder. 2 and 3 show one embodiment of the bobbin supporting means according to the present invention, and are a structural view and an operation explanatory view of the bobbin supporting means, respectively.
FIG. 4 is an operation explanatory view of the conventional multi-cup winder.

In FIG. 1, (1) is an automatic winder which has two bobbin holders (3) and uses the two bobbin holders by switching between them. (2) is an automatic doffing device, and the bobbin (5-
1, 5-2) Package (6-1, 6) wound on
-2) The package (6-
1 ', 6-2') is shown waiting on the doffing side. (7-1, 7-2) is a bobbin supporting means, and in conjunction with the movement of the pusher (4),
While supporting the bobbins (5-1, 5-2) so that the packages (6-1, 6-2) do not drop, they move to the doffing position.

Further, in FIG. 2, (12) is a sliding member, one end of which is fixed by an actuator (13) fixed to a machine base (not shown) of the multi-cup winder (1),
The bobbin holder (3) can be slidably moved in the axial direction. Further, the sliding member (12) includes an engaging member group (20,
21 and 22) are attached to the actuator (1
3) Engage with the doffing side tip of the shaft side spline (8) and the actuator (11).

A bobbin (5-2) having a package (6-2) formed on the shaft side spline (8).
The hole side spline (19) provided with the supporting means (7-2) for supporting the is fitted. The engaging member (23) attached to the sliding shaft (24) of the actuator (14) fixed to the sliding member (12) is slidable on the outer peripheral surface of the hole side spline (19). Hold on. Further, an actuator (9) is engaged with the engaging member (23), and a hole side spline (19) is attached to the actuator (9).
Engage. Therefore, the hole-side spline (19) is slidably slidable in the axial direction of the bobbin holder (3) by the actuator (14), and the center of the axial-side spline (8) is driven by driving the actuator (9). It can be rotated around its axis.

Further, an arm (10) having hole side splines at both ends is fitted to the shaft side spline (8), and a bobbin (package 6-1) having a package (6-1) is formed on the arm (10). Supporting means (7-1) for supporting 5-1) is attached. In this bobbin supporting means (7-1), the supporting means located closest to the doffing side is provided with an empty bobbin holding plate (26). Further, the arm (10) is provided with an actuator (11) that moves in association with the sliding member (12), and the actuator (1)
By the operation of 1), the arm (10) can be rotated around the central axis of the shaft side spline (8).

According to the apparatus configuration described above, the actuation of the actuator (9, 11) causes the shaft side spline (8).
The hole side spline (19) and the arm (10) rotate around the center axis of the. And the package (6-
The supporting means (7-2, 7-1) of the bobbin (5-2, 5-1) forming the (2, 6-1) is the bobbin (5-2, 5-).
1) Ascend to a position where it can support (state in FIG. 2). Then, the actuator (13) is activated to push the package (6-2, 6-1) to the doffing position.

Here, the doffing position may be such that all the bobbins (5-1, 5-2) are removed from the bobbin holder (3) as shown in FIG. The partial bobbin may be at a position still remaining in the bobbin holder (3). In short, bobbins (6-
If 1 ') is removed from the bobbin holder (3), add something.

Further, the bobbin formed with the wound yarn package may be pushed out by the pusher (4) described in FIG. 1, but the bobbin supporting means (7-2, 7-2,
The winder can be operated in conjunction with the bobbin supporting means (7-2, 7-1) by the contact plate (25) for pushing out the packages (6-2, 6-1) attached to 7-1). This is preferable because the pushing mechanism can be simplified.

The subsequent operation of the bobbin supporting means will be described with reference to FIG.

As described above, the winding package is pushed out to the doffing position (FIG. 3- (A)). And the packages (6-2 ', 6-1') extruded to the doffing position
Is first fried from the doffing side package (6-1 ') by an automatic doffing device (not shown in FIG. 3) (FIG. 3- (B)).

Next, as shown in FIG. 3- (D), the doffing side package (6-1 ') is doffed, and the bobbin supporting means (7-1') emptied is automatically fried. An empty bobbin (5-1 ') is supplied from the device. Here, the supply of the empty bobbin does not necessarily have to be performed at this stage, and may be performed at the next stage (FIG. 3- (E)).

After this, the bobbin supporting means (7-1 ') shown in FIG. 3- (C) is moved to the position shown in FIG.
-It is lowered to the position (7-1 '') shown in (D). Here, the descending means performs the following operations. That is, in FIG. 2, the actuator (11) operates to rotate the arm (10), and as a result, the arm (1) is rotated.
The bobbin supporting means (7-1 ″) attached to the position 0) is rotated and lowered.

Further, at the doffing position after the bobbin supporting means (7-1 ') is lowered, the yarn package (6-
The bobbin supporting means (7-2 '') forming 2 '') is pushed out by the contact plate (25) (Fig. 3- (E)).
This operation will be described again with reference to FIG.
4) operates to slide the hole side spline (19) fitted to the shaft side spline in the axial direction. As a result, the bobbin supporting means (7) attached to the hole side spline (19).
-2) moves to the doffing side together with the contact plate (25) provided on the supporting means (7-2), and the end face is pressed by the corresponding plate (25) (6-2 ') )
Are pushed to the doffing position.

Then, the yarn package (6-2 ″)
Is fried by an automatic doffing device (not shown) (FIG. 3- (F)), and the supporting means (7-
2 '') from an automatic doffing device to an empty bobbin (5-2 ')
Is supplied (FIG. 3- (G)). Here, it is needless to say that the supply of the empty bobbin does not necessarily have to be performed at this stage and may be performed at the next stage (FIG. 3- (H)).

After this, as shown in FIG. 3- (H), the bobbin supporting means (7-2 '') is retracted while supporting the newly supplied empty bobbin (5-2 ''). In the apparatus of FIG. 2, this movement is caused by the actuation of the actuator (14) to support the bobbin (5-2 '') by the supporting means (7-).
This is realized by retracting the hole side spline (19) provided with 2 ″).

Finally, the support means (7-1 ") of the bobbin (5-1") is raised to support the first doffing position (bobbins 5-2 'and 5-1', respectively). The means is 7-2 '
And position 7-1 '). At this position, the actuator (13) shown in FIG. 2 operates to retract the sliding member (12), thereby supporting means (7-2 ', 7-2', 7) of the bobbin attached to the sliding member (12). -1 ') also retreats at the same time. At this time, the supporting means for the bobbin closest to the doffing side is provided with a grip plate (26) for supporting the empty bobbin, and the empty bobbin is gripped by the grip plate (26). Bobbin support means (7-2 ', 7-1')
Winder bobbin holder automatically by retreating (3)
The empty bobbins (5-1, 5-2) are mounted on.

By the way, in the embodiment described here, the doffing of the yarn package of 2 cups is described.
The same operation procedure may be performed for doffing 3 cups or more. At this time, in FIG. 3- (G), the bobbin (5
-1 ") and the bobbin support means (7-1") need to be moved to the positions of (5-1 "" and (7-1 ""), respectively. Therefore, the "lowering means" referred to in the present invention is defined to include such an operation when doffing is performed in three or more stages.

Further, although the number of doffing yarn packages at one time is one package per doffing operation in this embodiment, it is not always necessary to doffing one package at a time. It is also possible to dodge at the same time.

Further, in the present embodiment, the descending means is realized by the combination of the actuator and the spline, but it goes without saying that it can be realized by using a known mechanism, for example, a link mechanism. Further, as the winder to which the present invention can be applied, not only the automatic winder described as the embodiment having two bobbin holders and automatically switching the wound bobbin and the empty bobbin alternately,
It goes without saying that it can also be applied to other manual multi-cup winders.

The apparatus described above was applied to an automatic winder for two cups of thick denier yarn made of polyamide. At this time, roll up the wound yarn package to the doffing pitch 2
In 2 minutes, doffing was performed using two automatic doffing devices. That is, doffing is done using two doffing devices.
It was divided into stages. First, the first automatic doffling device doffed the yarn packages on the doffing device side, and then the other automatic doffling device doffed the remaining yarn packages. As a result, the machine length of the doffing device in the doffing direction can be reduced to about half that of the conventional one. For this reason, the doffing work could be performed without trouble even with the equipment layout in which the winder groups were provided facing each other.

[0036]

That is, according to the present invention, by performing the doffing operation in multiple stages, it is not necessary to arrange all the wound-up packages in series, and the number of packages arranged in series at one time is eliminated. Can be divided. Therefore, the length of the doffing package in the doffing direction can be shortened, and when performing the doffing work using the automatic doffing device, the machine stand in the doffing direction of the automatic doffing device can be used. Since the size can be shortened and the mechanism of the automatic doffing device can be simplified, it is possible to provide a device having high reliability and low manufacturing cost.

Further, even in an equipment layout in which winder groups are provided so as to face each other, it becomes possible for the automatic doffing devices that run in opposition to rub against each other.
