Jan. 1, 1963 RYOHEI TSUZUKI SPINNING FRAMES 2 Sheets-Sheet 2 Filed Jan. 14, 1960 R YOHEI Buzz/W ATTORNEYS United States Patent 3,070,948 SPINNING FRAMES Ryohei Tsuzuki, Yamazaki-cho, Handa-shi, Japan Filed Jan. 14, 1960, Ser. No. 2,418 3 Claims. (Cl. 57-36) This invention relates to a spinning frame of a spinning machine in which a roving or sliver creel part of the spinning frame is arranged upstairs so as to constitute a roving or sliver chamber insulated from the downstairs and rovings or slivers delivered from creels or cans in said roving or sliver chamber are fed to a drafting part of said spinning machine installed downstairs just under said roving or sliver chamber.
A spinning frame of the conventional spinning machine is so constituted that a part for feeding rovings or slivers to the spinning machine proper is combined with other parts in one unit, and accordingly it is necessary to adjust temperature, humidity as well as air condition in a spacious room in which the spinning machine is accommodated, and it becomes difiicult to locally maintain the air surrounding the most important parts at a temperature and humidity suitable for spinning.
Moreover the above air conditioning to be effected throughout the large space requires not only a massive installation but also much expenses and it is very inefiicient. Particularly, it is difiicult to locally maintain water content of rovings or slivers, which gives the important influence to the effect of spinning, at a most suitable condition, and it is at the same time diflicult to feed such rovings or slivers directly to a drafting part of the spinning machine. Moreover the rovings or slivers are supported vertically at the upper part of the spinning machine in accordance with the heretofore used type so that the operation of converting them becomes inconvenient and also it results in deterioration of the yarn due to adherence of flying and dust to the fiber.
An object of this invention is to remove the above mentioned disadvantages and to spin an improved yarn in an extremely economical manner.
Other advantages are accomplished with this invention as explained hereinafter and illustrated in the accompanying drawings, in which:
FIG. 1 is a vertical longitudinal section of an embodiment of spinning frames in accordance with the present invention;
FIG. 2 is a front view of a creel supporting a bobbin;
FIG. 3 is a side view of the creel as shown in FIG. 2;
FIG. 4 is a vertical longitudinal section of another embodiment of the present invention;
FIG. 5 is an enlarged vertical section of the central portion of FIG. 4; and
FIG. 6 is its front view of FIG. 5.
Referring now to FIG. 1 of the accompanying drawings, there is a body 11 of a spinning machine which is of conventional but of which the roving or sliver feeding parts are taken out, and a ceiling 18 is provided on a top of a machine chamber 13, in which these spinning machines are accommodated, with such a height that it does not interfere with the actual spinning (about 7 feet above the floor), and a group of creels 12 for supporting bobbins 15 detached from the body 11 of the machine are arranged within a roving or sliver chamber 14 upstairs which is partitioned off from the above mentioned machine chamber 13. It is preferable in this case to make this roving or sliver chamber 14 small, in so far that the operation is not impeded.
The upstair roving or sliver chamber 14 is so constituted that air conditioning within said chamber may be effected independently from the downstair machine chamber 13, and air having high humidity delivered from a temperature and humidity adjusting chamber A is fed into the upstair roving or sliver chamber 14 through a duct B and a number of jet holes F provided at the upper part of the roving or sliver chamber 14. In this way about 10 percent of water content is given to the rovings or slivers within said roving or sliver chamber 14.
The bobbins 15 within said roving or sliver chamber 14 are supported horizontally on the creel 12, and rovings or slivers S delivered therefrom are fed to a drafting part 20 of the body 11 of the spinning machine through guide holes 19 which penetrate through parts of the ceiling 18 right above the drafting part 20.
Both ends of a bobbin holding shaft 15 of bobbins 15 are supported by V-shaped knife edges 22 made on the arms of the creel 12 as shown in FIGS. 2 and 3. By virtue of the arrangement of supporting the bobbins 15 horizontally in such a Way, rotation thereof becomes quite light, resistance caused in case of pulling out the slivers from the bobbins decreases remarkably and uneven drafting can be prevented, comparing with the conventional case Where bobbins are supported vertically on the creel.
Moreover it becomes possible to adopt an extremely large package or a double roving system in the present invention and also times of loading slivers may be decreased, since the device is not restricted by the shape and size of the creel.
Thus, according to the present invention, it is possible to give a relatively high water content to the rovings or slivers in the roving or sliver chamber 14 while completely separating the said downstair machine chamber therefrom so that production of flying and dust and their adherence to slivers become none at all and yarn having strong and fine quality can be obtained.
Furthermore, adjustment of temperature and humidity in accordance with the present invention can be done so effectively that the cost of providing such adjusting apparatus can be diminished remarkably. .Flufis are made few and cutting of yarns is decreased too, thus rendering much improvements in maintenance and management of the machine and economizing cost of labour.
In FIGS. 4, 5 and 6, a roving or sliver S delivered from the bobbins 15 is inserted into one of the guiding tubes 16 instead of directly supplying to the drafting part of the frame arranged downstairs. The sliver S is passed through the guiding tube 16 from its aperture 17. In case of double roving as shown in the drawings, a pair of slivers S is fed together with each other through the guiding tubes 16 to the drafting part 20 of the spining frame 11 installed at the downstairs. As above mentioned, the sliver S is fed to the drafting part 20 by means of the guiding tube 16. Instead of the bobbins 15 cans may be used in such a manner that the rovings or slivers are delivered from the cans and directed to the drafting part 20 through the guiding tube 16.
As is apparent from the foregoing description, in case the guiding tube is used the rovings or slivers S given with comparatively high water content in the sliver chamber 14 are passed through a thin guiding tube 16 and fed to the drafting part 20 so that the rovings or slivers S are intercepted more completely from the influence of the outside temperature and humidity, if compared with the device as shown in FIG. 1 and the slivers are drafted in the most favourable condition for spinning.
What I claim is:
1. An arrangement for spinning under controlled atmospheric conditions comprising a pair of superimposed chambers having a common partition therebetween with an opening therein, a spinning frame of a spinning machine positioned in the lowermost of said chambers, the uppermost of said chambers being completely closed except for said partition opening, a roving supply positioned within the uppermost of said chambers and having said roving fed through said partition opening to said spinning frame in a vertical downward direction and means for controlling the temperature and humidity in said uppermost chamber.
2. An arrangement for spinning under controlled atmospheric conditions as claimed in claim 1, wherein at least one guiding tube extends vertically through said partition opening and said roving extends from said ro ing supply through said tube to said spinning frame.
3. An arrangement for spinning under controlled atmospheric conditions as claimed in claim 1, wherein said roving supply includes creels and bobbins horizontally supported on said creels.
