39,765 (US-^-4,549,393) and FI? This paper relates to an improvement of a twisting spindle device using the direct spindle method described in No. 2,565,261.

[Prior Art] FIG. 1 shows an outline of the twisting spindle device disclosed in the above-mentioned documents, particularly PR-A-2,539.765. The twisting spindle device shown in FIG. 1 has a double twisting spindle shaft (indicated by the symbol D This is Surushino. In this spindle device, one of the yarn feeding wheel bins is installed on an extension line of the other yarn feeding bobbin. The piled yarn l supplied from the yarn supplying bobbin 3 is supplied to the rotary plate 5 in such a manner that it passes around the yarn supplying bobbin 4 that supplies the yarn 2 so as to form an arc 6.

Twisting of the threads 1 and 2 is performed at a fulcrum 7.

Furthermore, French patents 1,208,273 and 2,562,2
In the device described in No. 61, a dual head is used here. The twisted yarn 8 spun at the fulcrum 7 will remain the same whether or not further spindles are added afterwards.
It is wound up by a conventional means such as a winder 9. Reference numeral 10S 11 is a member provided in the spindle path so that the threads 1 and 2 are always supplied with a constant tension.

Since this spindle device requires a large area, various spindle devices have been proposed to date for the purpose of downsizing the spindle device and improving its operability. In these spindle devices, the spindle DT and the winder 9, which perform overlapping and twisting of the yarn, are installed on a support frame so that one is below the other, and the winding shaft rack and , the strand l is supplied to the yarn feeding bobbin 3 from any other arbitrary location,
A yarn feeding bobbin 3 is attached to a support frame below the spindle portion DT. Most of the spindle devices currently on the market have spindle portions of the same shape at symmetrical positions on both sides of a central support frame.

[Problem to be solved by the invention] Although the above-mentioned device is satisfactory in terms of miniaturization and operability, it requires a large number of members and the overall length of the device becomes extremely long. However, it is not possible to easily install and remove each bobbin (including the twisted yarn bobbin wound with the spun twisted yarn 8 and the yarn feeding bobbins 3 and 4 wound with the plain yarns 1 and 2), and complete automation is not possible. The problem was that it was difficult.

This invention has been made in order to solve the above-mentioned problems, and the present invention has been made in such a way that the spindle is capable of automatically attaching the yarn feeding bobbins 3 and 4 and removing the bobbin of the yarn winding machine 9 that has wound the twisted yarn 8. The device was improved.

Further, according to the device of the present invention, it is possible to reduce the size of the device and improve operability.

[Means for Solving the Problems] The twisting spindle device of the present invention enables continuous spindle operation, and has a pair of spindle shafts for spinning two threads supplied from two sources. The spindle parts are arranged side by side on a support frame, and there is a mechanism for winding up the spun twisted yarn.It has the following characteristics.

By providing a fixed supply at the final end of the spindle path,
a transfer belt that removes a bobbin that has wound the spun twisted yarn between two spindle parts placed on a support frame;
The support frame can be designed to contain part of two transport units, each consisting of a transfer belt on which a supply bobbin wound with yarn is attached, and two bobbins supplying the yarn are attached to the lower part of the support frame. placed facing each other.

[Example 7] This invention will be described below with reference to the drawings, but the invention is not limited to this example. Note that the same members described in FIG. 1 are denoted by the same reference numerals, and their explanations will be omitted.

As shown in the side view in FIG. 2, the device of the present invention has two spindles of the same shape placed on both sides of the device with the center 1l in between. The device is divided into two identical spindles DSC as shown in FIGS. 2, 4 and 5. The side surface of the spindle D side shown on the right side in FIG. 2 is shown in FIG. 3.

These two spindle parts D and G have double-twist spindle shafts for integrating and twisting the threads 1 and 2 supplied from supply sources 3 and 4, respectively. The yarn l supplied from the yarn feeding bobbin 3 is fed to a rotary plate 5 constituted by a double spindle shaft cylinder located inside the position of the yarn feeding bobbin 4 of the yarn 2. The twisting of two threads 1 and 2 is
This is done at the fulcrum 7, similar to the conventional spindle device. Furthermore, before the yarns 1 and 2 are twisted together at the fulcrum 7, the yarn 1
, 2 is provided with a tension adjustment member for adjusting the tension of the parts. Since the tension adjusting member of this device is used in a normal spindle device, a description thereof will be omitted. As shown, plain thread! , 2 are twisted together, a conventional double spindle shaft is used, each powered by an independent motor l2. The dual spindle shafts can also be operated simultaneously by an endless belt connected to a single motor. This kind of double spindle axis is
Since it is well known in the textile industry, a detailed explanation will be omitted here.

In this invention, in order to downsize and automate the apparatus, two spinning sections of the apparatus, denoted by symbols D and G, are spaced apart from each other at regular intervals. Spin jli to position! ! A support frame is designed to support the shaft. As shown in FIG. 2, the support frame is roughly composed of a bottom frame l3 and vertical frames l4 and l5. The vertical frames l4, l5 and the connection frame connecting them are both firmly assembled. It goes without saying that the frame shape is not limited to that shown in FIGS. 2 and 3, but may be any shape equivalent to this.

Each member constituting the spindle portion is installed outside the frame assembled as described above. FIG. 3 is a front view of this spindle. In order to improve the productivity of the device, a plurality of spindles of this type may be provided.

A winding mechanism connected to each spindle section and indicated by reference numeral l6 is a conventional winding mechanism for winding the thread onto the bobbin. The bobbin 9 of the winding mechanism 16 is shown in FIG. 1, and the bobbin 9 on which the twisted yarn is wound is shown in FIG.

In the gap 11 between the vertically erected vertical frames l4 and 15, vertically stacked transport units 17 and 1B each having a transport belt are installed.

Then, one transport unit I8 removes the pobbin 9 on which the spun twisted yarn is wound, and the other transport unit l
Reference numeral 7 is used to attach a yarn supply bobbin 3 for supplying yarn.

FIG. 4 shows how the used yarn feeding bobbin is removed, and FIG. 5 shows how the yarn feeding wheel bin 3 is attached.

The manufacturing apparatus of the present invention is characterized in that two yarn feeding bobbins 3 and 4 wound with yarns 1 and 2 are mounted on both sides of the support frame so as to face each other on the bottom l3 of the support frame. .

Furthermore, as is clear from FIGS. 4 and 5, the two spindle portions D1G provided back to back may be interchanged with each other.

By doing as described above, complete automation of the device becomes possible.

The bobbin 9 with the twisted yarn wound thereon is removed and placed on the transport belt 18 by means of a clamp mounted on the support rack. After the bobbin is removed, the empty tube is returned from the removal position to the yarn winding position, as shown in FIG.

When considering attachment and detachment of the yarn supply bobbins, it is necessary to take into consideration the spare bobbin 3' prepared for each yarn supply bobbin 3. When the yarns 1 and 2 wound around the yarn feeding bobbins 3 and 4 are used up, the yarn feeding bobbins 3 and 4 are removed by the transport belt l7, and new yarn feeding bobbins 3 and 4 are also transported by the transport belt 17. Supplied. Further, when the newly supplied yarn feeding bobbins 3 and 4 are used up, the next yarn feeding bobbin is sequentially supplied.

[Effects of the Invention] According to the device of the present invention, not only is it possible to automate each member, but also means for installing various members and removing a used bobbin are all provided at the final end of the spindle path. This allows for easy loading and unloading of the bobbin.

This type of device also solves the problem of miniaturization of the device.
