Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic winder package manufacturing apparatus for manufacturing a cone package using a grooved traverse drum.

[0002]

2. Description of the Related Art Generally, a nominal 6-inch traverse width (varies slightly depending on each manufacturer, for example, 140 to 1
Weft unwinding speed of 2,000 / min in an automatic winder producing corn packages (varies in the range of 60 mm)
In order to manufacture a cone package having a short traverse width such as a traverse width of 3 inches or 4 inches as a weft package for an ultra high speed air jet loom of 0 to 2,800 m, a grooved traverse drum of a package manufacturing apparatus,
Modifications were required to replace parts such as the winding bobbin, bobbin holder, drum cover, end face drop prevention cover, and suction mouse.

[0003]

However, there has been a problem in that the replacement parts required for the above-mentioned modification and the cost of modification such as replacement work are expensive.

In the present invention, a device for producing a cone package having a nominal 6-inch traverse width can be converted into a device capable of producing a cone package having a short traverse width such as a nominal 3-inch or 4-inch by replacing as few parts as possible. The purpose is to reduce the cost of remodeling.

[0005]

In order to achieve the above-mentioned object, the present invention provides a spiral groove, which is replaceably mounted on a drive shaft and which reciprocally traverses a yarn in a predetermined width in the axial direction of the drive shaft. A grooved traverse drum formed on a surface and a winding bobbin holder are rotatably supported, and rotate in contact with the drum to reciprocally traverse on the drum to wind up a yarn to produce a cone package. In a package manufacturing apparatus for an automatic winder, which has a taper-shaped winding bobbin, a drum cover and an end face drop prevention cover installed on the front side of the drum, and a suction mouth that sucks out the yarn end of the package at the time of yarn breakage, Attach the winding bobbin, bobbin holder, drum cover, end face drop prevention cover and suction mouth to a cone pad with a nominal 6-inch traverse width. A cage-sized one is used in common, and the drum has the same turn portion of the groove on the small diameter side of the cone package, and only the groove traverse width has a nominal 3 inch traverse width to 6 inch traverse width. , A cone package having a nominal 3-inch traverse width to a 6-inch traverse width is manufactured by selecting from other shapes having the same size.

[0006]

With the automatic winder package manufacturing apparatus having the above-described structure, it is not necessary to replace parts such as the winding bobbin, the bobbin holder, the drum cover, the end face drop prevention cover, and the suction mouse. Cone packages from 3 "to 6" traverse width can be manufactured with the same equipment. The reason is that the drum has the same turn portion of the groove on the small diameter side of the cone package, the traverse width of the groove is the nominal 3 inch traverse width to 6 inch traverse width, and the other shape dimensions are the same. By selecting and using from the inside. That is, when manufacturing a cone package having a short traverse width such as a nominal 3 inch or 4 inch with a device for a nominal 6-inch traverse width, the conventional idea is to set the traverse center of the yarn by the drum at the same position. I'm thinking that this is not only for the drum, but for the winding bobbin, bobbin holder, drum cover,
Unless the parts such as the end face drop prevention cover and the suction mouth are also replaced, it is impossible to manufacture a corn package with the shapes of both ends neat, and if it is used as a weft yarn for an air jet loom, it may cause unwinding of the yarn. Problems such as yarn breakage occur frequently, and the production efficiency of the air jet loom decreases.

According to the present invention, one end of the traverse width of the yarn by the drum, in particular, the position of the turn portion of the groove on the small diameter end side of the cone package is all the same for each size drum, and only the traverse width is different, By using a drum that has the same shape, all the small diameter end side where roll collapse is likely to occur, the end face drop prevention cover and the drum cover are used to accurately guide and regulate so that a cone package with no roll collapse can be manufactured. It is the one.

Since the large-diameter end side of the cone package originally has a shape in which winding collapse is unlikely to occur, even if the parts other than the drum are left for 6 inches, even if the drum has a corresponding size, It has been confirmed that when a cone package having a short traverse width such as 3 inches or 4 inches is manufactured by using it, the guide groove of the yarn on the large diameter end side is sufficient only by the groove of the drum.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view of a drum of an automatic winder package manufacturing apparatus to which the present invention is applied.
Is a drum, (2) is a groove formed in a spiral shape on the peripheral surface of the drum (1), (2a) is a turn portion of a groove forming the large-diameter side end surface of the cone package (3), (2b) () Shows the turn part of the groove | channel which forms the small diameter side end surface of a cone package (3), (L) shows the traverse width of a groove | channel (2).

FIG. 2 is a schematic side view of an automatic winder package manufacturing apparatus to which the present invention is applied. (4) shows an end face drop prevention cover, (5) shows a drum cover,
(6) shows a suction mouth that sucks out the yarn end of the cone package (3) at the time of yarn breakage, (7) shows a winding bobbin, and (8) shows a winding bobbin holder.

The drum (1) is replaceably mounted on a drive shaft (10) which is rotatably driven on the machine frame (9), and the yarn is threaded in a predetermined width (axial direction) of the drive shaft (10). L), a spiral groove (2) for reciprocating traverse is formed on the outer peripheral surface.

In the present invention, the traverse width (L) of the drum (1) for a nominal 6-inch size varies depending on the manufacturer (for example, if there are variations in the range of 140 to 160 mm, the manufacturer). The dimensions should conform to the specifications. Further, the drum (1) used when manufacturing the cone package (3) having a traverse width shorter than 6 inches nominally includes the turn portion (of the groove (2) forming the end surface on the small diameter side of each cone package (3) ( 2b) are all in the same position, and only the traverse width (L) of the groove (2) is made to match those dimensions. Ie, nominal 3
For inches and 4 inches, match only the traverse width (L) of the groove (2) with those dimensions,
However, the turn portion (2b) of the groove (2), in particular, the turn portion (2b) of the groove (2) forming the small-diameter side end surface of the cone package (3) is replaced by the drum (1) of each traverse width (L). All are the same. When a drum (1) having a traverse width (L) of 6 inches or less is produced, a preferable traverse width (L) range is 70 to 120 mm.

The reason is that when the length is 70 mm or less, the yarn is not folded back at the turn portion (2a) of the groove (2) forming the large diameter side end surface of the cone package (3). Further, since the cone package (3) manufactured from the drum (1) having a traverse width (L) of 120 mm or more has a long traverse width (L), unwinding property is poor when unwinding at a high speed in a subsequent process, Not suitable as a weft package for high speed air jet loom.

The end drop prevention cover (4), the drum cover (5), the suction mouth (6), the winding bobbin (7) and the winding bobbin holder (8) used in the present invention have a nominal 6 inch traverse width. The case of manufacturing the cone package (3) is used as it is when manufacturing the cone package (3) of each traverse width. The drum cover (5) is mounted on the drive shaft (10) so as not to hinder the traverse movement of the yarn (1).
It is attached to the machine frame (9). The end face drop prevention cover (4) controls the traverse range of the yarn by the turn portions (2a) (2b) at both ends of the groove (2) of the drum (1), and is arranged on the front side of the drum (1). , Mounted on the machine frame (9).
When the yarn is broken, the suction mouth (6) sucks out the yarn end of the cone package (3) and guides it to a knotter (not shown). The suction mouth (6) is supported by a machine frame (9) and is attached to a pneumatic device (not shown). It is connected. The winding bobbin (7) has a taper shape, and both axial ends thereof are rotatably supported by the winding bobbin holder (8), and rotation is imparted by contacting the drum (1), whereby the winding bobbin (7) is rotated. The yarn which is reciprocally traversed in the groove (2) of the drum (1) is wound up to manufacture a cone package (3). The take-up bobbin holder (8) has a structure in which the take-up bobbin (7) can be attached / detached, and can also move upward as the winding diameter of the cone package (3) increases. 9) Supported above.

The drum (1) of the present invention has the same outer diameter, axial length and structural shape of the mounting portion to the drive shaft (10) for each traverse width, and the cone package (3) has a small diameter. The turn portion (2) of the groove (2) forming the side end surface
The axial formation position from the drum end surface of b) is set to be the same for all the drums (1) of each traverse width, and only the individual traverse width (L) is changed.

With the above structure, 70-120 m
In the longitudinal central axis direction of the drum (1) of the turn portion (2b) of the groove (2) forming the end surface on the small diameter side of the cone package (3) manufactured by the drum (1) of the present invention having a traverse width of m. Position is a 6 inch traverse drum (1)
Since it is in the same position as above, it is not necessary to replace the end face drop prevention cover (4) on the small diameter side end face of the cone package (3) formed by the nominal 6-inch traverse drum (1).

The shape of the drum (1) having a traverse width of 70 to 120 mm according to the present invention is the drum (1) for producing a cone package (3) having a nominal 6-inch traverse.
The drum cover (5) and the suction mouth (6) do not need to be replaced because of the same size as the shape of the.

Furthermore, the shape of the winding bobbin (7) of the cone package (3) manufactured by the drum (1) having the traverse width of 70 to 120 mm according to the present invention is such that the cone package (3) has a nominal 6-inch traverse. Since the winding bobbin (7) has the same shape as the winding bobbin (7) used in manufacturing, it is not necessary to replace the winding bobbin holder (8) and the weft package holder of the air jet loom in the subsequent step.

In the above-mentioned embodiment, one type of drum and package manufacturing apparatus of a large number of automatic winder package manufacturing apparatuses are shown and described, but the present invention is not limited to this and any type of package manufacturing apparatus can be used. It is applicable to automatic winder drum and package manufacturing equipment.

Further, the position where the turn portion (2b) of the groove (2) forming the end surface on the small diameter side of the cone package (3) is formed in the axial direction from the drum end surface is the drum (1) of each traverse width.
It is most preferable that the end face drop prevention cover (4) is adjustable in the longitudinal center axis direction of the drum (1) at the turn portion (2b) position of the end face drop prevention cover (4). The effect does not change by adjusting the end face drop prevention cover (4) even if it varies in the longitudinal center axis direction of the end face fall prevention cover (4) of the turn portion (2b). The variation within the adjustment range of directions falls within the range of the same position.

The groove (2) of the drum (1) of the present invention may be the same or different in the number of turns in the forward path and the backward path, and the pitch may be equal pitch or unequal pitch. But it's okay. However, it is preferable that the number of turns of the groove (2) is larger in the outward path (the direction in which the yarn is traversed from the small-diameter side end to the large-diameter side end of the cone package). ) Is good, and the pitch of the grooves (2) is preferably a unequal pitch for the cone, so that the shape of the manufactured cone package (3), in particular, the shape of the end surface on the small diameter side becomes good.

[0022]

According to the present invention, a drum for converting an automatic winder manufacturing apparatus for manufacturing a nominal 6 inch traverse cone package into an apparatus for manufacturing a nominal 3 inch or 4 inch traverse cone package is used. It is possible to remodel by exchanging only one, and there is an advantage that the remodeling cost is significantly reduced.
