Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is directed to the field of spinning machines. More particularly, the present invention relates to the fine cleaning of textile fibers and to a method and a device for performing the method.
2. Description of the Related Art
Textile fibers, particularly cotton fibers, are subjected to coarse cleaning after the fiber bales have been opened, during which the coarse contaminants are removed. The fibers are then subjected to a fine cleaning. With the fine cleaning, all the particles of dirt remaining in the fibers after the coarse cleaning should be removed as much as possible. After the fine cleaning, the fibers are then transported to the next preparation step of the spinning process, for example, to a carding machine.
In the fine cleaning machine, the fibers, in the form of a fiber bat, are conveyed over a toothed, central opening roller through various cleaning steps. During the rotation of the opening roller, the bat is continuously subjected to centrifugal force and, thereby, the contamination particles are concentrated in the outer layers of the bat. In one of the cleaning steps, the centrifuged bat is guided under separating blades in such a way that the uppermost layer with the concentration of particles is separated from the remainder of the bat.
Typically, a guide element is provided which projects into the bat in front of a separating blade, that is, against the transport direction of the fibers. On this guide element the bat is deflected inwardly, i.e., against the centrifugal force, whereby the concentration of the contamination particles is increased. The succession of separating blades and guide elements are repeated at least twice within the same cleaning step.
So that a cleaning step of this type, with separating blades and guide elements, can operate optimally for every fiber origin and for every blend of fiber origin, it must be appropriately adjustable so that all the contamination particles and, as much as possible, only the contamination particles are separated from the fibers.
The fine cleaning machines at the present stage of technology are manually adjustable in such a way, that through adjusting screws or other means, the position of the separating blades and guide elements are adjustable and such that guide elements of different sizes can be fitted. Since every adjustment and setting requires manual intervention with the machine, such adjustments and settings tend to be inconvenient and costly. Further, it is only possible to reset the positions of the separating blades and guide elements for different fiber origins or blends of origins during a machine stoppage.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a device for the fine cleaning of textile fibers with which the fiber bat, rotating on an opening roller, is guided past separating blades and guide elements for the purpose of cleaning of the fiber bat. The device is to be remotely controlled and finely optimized and set for a fiber origin or a blend of fiber origins without manual intervention. Further, the device is to be capable of adjusting the settings of the separating blades and guide elements during the cleaning process cycle. The number of parameters with can be set, and the range of adjustment, are to be of such a type that the optimal fine cleaning can be carried out for a broad spectrum of fiber origins. The settings for all the pairs of separating blades and guide elements comprising the same cleaning steps are to be possible with the same setting mechanism.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 shows the device according to the invention with all of its component parts. Shown therein is an exemplary embodiment with two separating blades and three guide elements. Other numbers of separating blades and guide elements could alternatively be provided within the scope of the invention.
On the extreme outside of the periphery of a toothed opening roller 1, the so-called "beater circle" S, the fiber bat is moved to be cleaned by the device according to the invention in the direction of the heavy arrows. In the transport direction, the bat, which is previously subjected to the centrifugal force before the particular cleaning device according to the invention, and through which the contamination particles have concentrated in the outside zone, is first passed under a guide element 10.1. The guide element projects into the transport path of the fiber bat and deflects the bat inwardly, that is, against the centrifugal force, which thereby further intensifies the radial separation into contaminants and fibers.
A separating blade 9.1 follows the guide element in the transport direction of the fibers. The bat is passed beneath separating blade 9.1 and, by means of this arrangement, is separated into a fiber portion and a contamination portion. A second guide element 10.2, a second separating blade 9.2, and a third guide element 10.3 follow the separating blade 9.1.
So that the device according to the invention can be set for fibers from different origins or blends from different origins, the following dimensions can be set:
the space 1 between the separating blades 9.1 and 9.2 and the beater circle S;
the space 1 between the guide elements 10.1, 10.2, and 10.3 and the beater circle S; and
the space 1: between each guide element 10.1 and 10.2 and a respective separating blade 9.1 or 9.2.
In FIG. 1, three levers 2, 4, and 6 are also shown, with the help of which the aforementioned three spaces 1.sub.1, 1.sub.2, 1.sub.3, can be remotely set through a motorized drive. For example, it is contemplated that each of the levers could be operatively connected with a respective fluid-actuated jack which is selectively controllably positionable by means of a controller. Upon a determination that a fiber bat of a particular origin, or blend of origins, is to be cleaned, the appropriate control signal(s) would be sent to the controller(s) for the respective jacks for appropriately positioning any number or all of the levers 2, 4, and 6, based upon the fiber origin, the blend of fiber origins, or other known characteristic of the fiber or the fiber bat. It is also contemplated that the respective levers 2, 4, and 6 could be remotely manually operated to appropriately set the aforementioned spaces 1.sub.1, 1.sub.2, 1.sub.3.
With more specific reference to the motion of the lever unit, when the lever 2 moves about axis B, as shown with dash-dotted lines in FIG. 1, then the entire device moves away from the beater circle, that is, 1.sub.1 and 1.sub.2 become greater to the same extent. The respective positions of the lever 2 and the separating blades 9.1 and 9.2 shown in FIG. 1 represent their nearest positions to the beater circle during operation of the cleaning device of the invention.
When the lever 4 is moved about axis C, as shown in FIG. 1 with dash-dotted lines, then the guide elements 10.1, 10.2, and 10.3 move away from the beater circle, while the separating blades 9.1 and 9.2 retain their positions, that is, 1.sub.2 becomes greater while 1.sub.1 remains the same. The respective positions of the lever 4 and the guide elements 10.1, 10.2, and 10.3 shown in FIG. 1 represent the nearest positions to the beater circle with relation to the separating blades.
When the lever 6 is moved about axis G, as shown in FIG. 1 with dash-dotted lines, then all of the guide elements 10.1, 10.2, and 10.3 move in the transport direction of the bat, without alteration of their own radial positions or that of the separating blades 9.1 and 9.2 relative to the beater circle S. In other words, each of the guide elements 10.1, 10.2 move against a respective one of the separating blades 9.1, 9.2 and, thereby , distance 1.sub.3 becomes smaller. In the position of the lever 6, the guide elements 10.1, 10.2, 10.3, and the separating blades 9.1, 9.2, distance 1.sub.3 has the greatest possible value.
Variations of the embodiment of the invention shown in FIG. 1 are contemplated. For example:
the first element 10.1 can be omitted;
a third separating blade can follow behind the third guide element 10.3, i.e., the separating device can consist of three pairs, each comprising one guide element and one separating blade; and
the entire cleaning step can comprise more than three pairs, each comprising one separating blade and one guide element.
FIG. 2 shows the device according to the invention from a direction which is perpendicular to the axis of the opening roller 1. From this, it can be seen how the device according to the invention is arranged on the front face of the opening roller.
The face of the opening roller is covered by a housing 11. The lever unit for the operation of the setting of the guide elements and the separating blades, which is explained in greater detail below in conjunction with the remaining figures, is fitted on the side of the housing 11, which faces away from the opening roller. The separating blades 9.1 and 9.2, as well as the guide elements 10.1, 10.2, and 10.3 extend parallel to the axis of the opening roller 1 over their entire length. Neither the separating blades nor the guide elements can be seen in FIG. 2. However, the three pairs of pins L1/M1, L2/M2 and L3/M3 can be seen, which make the connection between the lever unit and the guide elements 10.1, 10.2 and 10.3. Likewise, the two pairs of pins J1/K1 and J2/K2 which connect the lever unit with the separating blades 9.1 and 9.2 are also shown.
The pins L1/M1, L2/M2, L3/M3, and J1/K1, J2/K2, as well as B, C, G, I, H, and E are generally represented in FIG. 2 with dashed lines.
A lever unit on the opposite face of the opening roller is contemplated, which would be formed as a mirror image of the lever unit shown in FIG. 2. In this case, this lever unit could be operatively connected in parallel with the aforementioned motorized drive, although both lever units could be activated by a common controller.
The lever unit consists of three devices, each for the setting of a respective cleaning parameter 1.sub.1, 1.sub.2, 1.sub.3. Thereby, the lever 2 and the plate 3 comprise a first device for the radial setting of the entire device (i.e., controlling 1.sub.1 and 1.sub.2 together) on which all the other parts of the device are fitted.
In addition to the lever 4, an intermediate lever 5 and a transverse lever 8 comprise a second device for the setting of the radial position of the guide elements 10.1, 10.2, and 10.3 (i.e., controlling only parameter 1.sub.2).
In addition to the lever 6, a transverse lever 7 comprises a third device for setting the spacing between the guide elements and the separating blades (i.e., controlling parameter 1.sub.3).
FIG. 3 illustrates the device for setting the spacing between the entire device and the beater circle S (for setting the parameters 1.sub.1 and 1.sub.2). The pair of pins J1/K1 and J2/K2 which rigidly connect the plate 3 with the separating blades 9.1 and 9.2, extend parallel in the housing 11 in guides Z, (see also FIGS. 1 and 2), which run parallel to the radius of the opening roller 1 through the middle of the plate 3. Pin C is pivoted on the plate 3 and connects the plate with the lever 2. When the lever 2 swivels on the pin B on the housing 11, the plate 3 moves in guides Z mentioned above. The slippage resulting from such a movement of the pin C moves this along the appropriate slot in the lever 2. The two separating blades 9.1 and 9.2 and the guide elements 10.1, 10.2, and 10.3 move in the radial direction of the opening roller 1.
FIG. 4 illustrates the device for setting the spacing between the guide elements 10.1, 10.2, and 10.3 and the beater circle S (setting of parameter 1.sub.2). This spacing is primarily determined through the position of the plate 3 in relation to the beater circle S, but it can, however, still be increased independently of the position of the plate 3. The guide elements 10.1, 10.2, and 10.3 are connected to the transverse lever 8 through the pairs of pins L1/M1, L2/M2, L3/M3. In turn, the transverse lever 8 is connected with the intermediate lever 5 through the pin I. The intermediate lever 5 is pivoted on the lever 4 through the pin G. When the lever 4 is swivelled on the pin C pivoted on the plate 3, the pin G, which has an appropriate guide on the plate 3 (visible in FIG. 3) moves and draws the intermediate lever 5 with it, whereby the pin E, which is rigidly connected with the intermediate lever 5, is guided in a radially running guide (seen in FIG. 3) in the plate 3 and the pin I carries the transverse lever 8 with it. Since the transverse lever 8 is connected to the pairs of pins L1/M1, L2/M2, and L3/M3, these pins move with the guide elements 10.1, 10.2, and 10.3, neglecting the swivel motion of the intermediate lever 5, parallel to the radius of the opening roller 1 running through the middle of the plate 3.
FIG. 5 shows the device for the setting of the clearance between each guide element 10.1, 10.2 and a respective separating blade 9.1, 9.2 (setting of parameter 1.sub.3). The pairs of pins L1/M1, L2/M2 (and also L3/M3) also connect the guide elements 10.1, 10.2 (and also 10.3) with the transverse lever 7. The transverse lever 7 however does not join in the movement actuated by the lever 4 (see FIG. 4), since the pins L1, M1, L2, M2, L3, and M3 slide in corresponding radial slots U.M1, U.L1, U.M2, U.M3,, and U.L3 in the transverse lever 7. The transverse lever 7 is connected through the pin I with the lever 6 which pivots on the pin G. If the lever 6 is swivelled on the pin G, then the pin I moves in its guide V on the intermediate lever 5 in a concentric circle to the beater circle S. Thereby, the pins G and E slide in appropriate slots of the plate 3 (shown in FIG. 3). The transverse lever 7 joins in this movement and is thereby guided through the pin H in the appropriate slot T in the plate 3. The guide elements 10.1, 10.2 (and 10.3) are thereby displaced on a circle concentric to the axis of the opening roller 1, in the direction towards the appropriate separating blades 9.1 and 9.2. Thereby, their radial position relative to the opening roller and relative to the separating blades 9.1, 9.2 is not altered.
No further functions are described with reference to FIGS. 6, 7, and 8, although these figures provide an instruction for the assembly of the lever unit of the invention.
FIG. 6 shows the plate 3, the lever 2 with the pin B, and the intermediate lever 5, as well as the pairs of pins L1/M1, L2/M2, and L3/M3, which project through the plate 3 and the housing 11, the points where the pairs of pins J1/K1 and J2/K2 which are fastened on the side of the plate 3 facing away from the lever unit, the pin C, which is pivoted in the plate 3, the pins G, E, and H, which are guided in the appropriate guides in the plate 3, and the pin I, which is pivoted in the intermediate lever 5.
FIG. 7 shows the lever 6 and the transverse lever 7, additionally to the parts of the lever unit which have already been explained in connection with FIG. 6.
FIG. 8 shows the transverse lever 8 and the lever 4, additionally to the parts of the lever unit which have already been explained in connection with FIGS. 6 and 7.
Finally, although the invention has been described with reference of particular means, materials and embodiments, it is to be understood that the invention is not limited to the particulars disclosed and extends to all equivalents within the scope of the claims.
