Description

[Detailed description of the invention] [Field of industrial application] The present invention is an improvement of a creel stand for a yarn feeder in progress, which is used for a large yarn feeder for rough warping of warp knitting or fabrics, etc. This invention relates to a creel stand for loading a yarn supplying body, which is improved so that more large yarn supplying bodies can be set in a creel stand of a certain size in which installation space is limited.

[Conventional technology and technical issues to be solved]

As is well known, the creel stand for the yarn feeder is provided with a plurality of pegs of the same length arranged in the vertical and horizontal directions of the main body in a bracket shape, and each peg is filled with bread, cheese, corn, etc. The yarn feeder is inserted and hung, and the raw yarn from each yarn feeder is supplied to the warping machine via a tension compensator (yarn tension adjustment device) installed in the axial direction of each peg. .

Incidentally, in recent years, with the rationalization of yarn production by yarn manufacturers, the diameter of yarn feeders for rough warping of warp knitting or fabrics has become larger than conventional yarn feeders. Therefore, the reality is that in conventional creel stands, the intervals between the pegs are narrow, making it impossible to set the yarn in a large yarn feeder.

Therefore, it may be possible to create a creel stand that can accommodate a large yarn feeder by making the interval between each PETSU wider than the previous one, but this would inevitably result in an increase in the size of the creel stand and the use of other yarn feeders with different yarn diameters. In order to avoid such problems, even if we create a creel stand that can install a large yarn feeder in the existing space in the factory. However, as the number of pegs decreases, the total number of large yarn feeders also decreases, resulting in a disadvantage that the efficiency of supplying yarn to the warp yarns deteriorates.

The present invention has been developed in view of the above-mentioned difficulties in conventional creel stands, and allows more large yarn feeders to be installed in a creel stand of a certain size with limited installation space. It is a technical problem to provide a practical creel stand for a yarn feeder that can uniformize the yarn tension of the yarn regardless of the placement position of the yarn feeder and efficiently supply the yarn to the warping machine. do.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above problem will be explained below with reference to the accompanying drawings.

That is, the creel stand of the present invention includes a short peg row 1 in which a plurality of short pegs 11, 12, . A long peg row 2 in which a plurality of long pegs 21, 22, on which the yarn feeder Y is set on the front side of the short peg row 1, are arranged in a bracket shape in a staggered manner with each peg in the row direction of the short pegs. and a means of increasing the number of yarn supplying bodies set by alternately providing the yarn supplying bodies Y set in each of the short pegs 11, 12, etc.; A yarn guide 3 is disposed in front of each of the short pegs 11, 12 in the axial direction so as to be the same as the yarn pull-out angle B from the yarn supplying body Y set on each of the long pegs 21, 22. The above technique is achieved by employing a combination of the following: making the yarn tension of the yarn supplying body Y set on the short peg row 1 uniform with the yarn tension of the yarn supplying body Y set on the long peg row 2; The problem was solved.

〔Example〕

Hereinafter, the present invention will be described in more detail based on embodiments shown in the accompanying drawings. In addition, FIG. 1 is a schematic side view showing a process train for supplying yarn from a creel stand to a warping machine via a front roller tension adjustment device according to the present invention, and FIG. 2 shows an example of the same process. FIG. 3 is a partially enlarged plan view showing essential parts of the creel stand according to the present invention, and FIG. 4 is a partially enlarged plan view showing a modification of the creel stand.

In the drawings, what is designated by the symbol R is the mount body of the stand of this embodiment in which the pegs for the yarn feeder device are aligned and arranged, and although a columnar shape is normally used, in the embodiment, a flat plate shape is used. It has been made. Short peg rows 1 and long peg rows 2 are alternately provided on the pedestal main body R at equal intervals in the lateral direction of the gantry main body R, and each of the peg rows 1 and 2, which will be described later, A known tension compensator 4 is provided at the front in the axial direction to automatically adjust the thread tension within a predetermined range (see FIGS. 1 to 4).

The short peg row 1 consists of a plurality of short pegs 11, 12, etc. arranged in a bracket shape on the gantry main body R, and the peg rows 1, 1, 12, .
Each of the pegs 11, 11, 12, 12... of 1, and each of the upper and lower pegs 11, 12... of the gantry body R in the vertical direction.
are equally spaced from each other and each peg 11, 12
The large yarn supplying bodies Y to be set on... are arranged in alignment so that they do not come into contact with each other.

In front of the short peg row 1, a thin plate-like thread guide 3 extending in the longitudinal direction of the gantry main body R is provided (see FIGS. 2 and 3). The yarn guide 3 is provided at a position where the yarn pull-out angle A of the yarn feeder Y attached to each peg 11, 12... is the same as the yarn pull-out angle B from the long pegs, which will be described later. A through hole 3a for guiding the progress of the yarn is bored at a location facing the axis of each peg 11, 12, . . . . As a result, the raw yarn of the yarn supplying body Y is transferred to the yarn guide 3.
The respective pegs 11, 12, . . .
is introduced into the corresponding compensator 4.

On the other hand, the long peg row 2 has short pegs 11,1
2. Long pegs 21, 22 formed longer than...
... in the row direction of the short pegs, each peg 11,
12... are arranged in a staggered manner on the frame body R in a bracket shape. Then, each peg 21, 21, 22, 22 in the lateral direction of the gantry main body R
The arrangement of... and the arrangement of each peg 11, 12... in the vertical direction of the frame main body R are the same arrangement relationship as in the case of the short peg row 1, that is, each peg 2
The large yarn feeders Y set at 1, 22, etc. are aligned so that they do not come into contact with each other. The raw yarn of the yarn feeder Y set on each of these pegs 21, 22... is directly introduced into the compensator 4 corresponding to each of the pegs 21, 22... with a predetermined drawing angle B.

Therefore, when a large yarn feeder Y for rough warping of warp knitting or woven fabric is set on the stand of this embodiment, the yarn feeder Y set on the short pegs 11, 12, etc.
The yarn feeder Y set on the long pegs 21, 22... are set on one side of the gantry body R in a zigzag superimposed state where they partially overlap, compared to a conventional creel stand using pegs of the same length. Thus, it becomes possible to set up about twice the number of yarn supplying bodies Y.

In addition, the yarn feeder Y installed in the short peg row 1 is
The yarn is introduced into the compensator 4 via the yarn guide 3 so that the yarn pull-out angle A is the same as the yarn pull-out angle B in the long peg row 2. The yarn tension of Y is the same as the yarn tension of the yarn supplying body Y pulled out from the long pegs 21, 22, . . . , and the yarn tension becomes uniform regardless of the setting position of the yarn supplying body Y.

The creel stand for the yarn feeder in this embodiment is generally constructed as described above, but the present invention is by no means limited to the above-mentioned embodiment, and within the scope of the "Claims for Utility Model Registration". Various design changes and configuration additions are possible. For example, as shown in FIG. 4 in the above embodiment, the thread guide 3
is formed into a cylindrical shape and removably attached to the compensator 4 in a cantilever shape, and the raw yarn of the yarn feeder Y set in the short peg row 1 is led out to the compensator 4 through the through hole 3a. , or, as shown in FIG. 3, short pegs 51, 52... are provided in a bracket shape at the long peg attachment portion of the gantry body R, and each of the short pegs 51, 52...
The long pegs 21, 22... may be removably inserted and fixed, or the long pegs 21, 22... may be removably inserted and fixed.
22... from the short pegs 51, 52... and remove the thread guide 3, and remove the long pegs 21, 22...
It is of course planned in the present invention to add a configuration in which relatively small-diameter yarn feeders such as pirns or cones are attached to each of the short pegs 51, 52... from which the short pegs have been removed, and each of the short pegs 11, 12... of the short peg row 1. By the way, this configuration has the advantage that it can be used in combination with thread supply bodies having different diameters.

[Effect of idea]

As explained above with reference to the embodiments, according to the creel stand for setting yarn feeders of the present invention, the yarn feeders set in the long peg row partially overlap in front of the yarn feeders set in the short pegs. Since the threads are stacked in a staggered manner, the number of yarn feeding devices for the main body of a creel stand of a certain size with limited setting space is increased, and the yarn pull-out angle of the yarn feeding body set on the short pegs is also increased. The yarn guide makes the yarn pull-out angle the same as that in the long peg, so
The yarn tension of the raw yarn is made uniform regardless of the position of the yarn feeder relative to the gantry body, and the raw yarn can be efficiently supplied to the warping machine without increasing the size of the creel stand.
