Definitions

  • the present invention relates to a pivoting system for turbine housings of open-end spinning machines in which the turbine housing with the spinning turbine mounted therein is pivotable about a horizontal pivot axis extending parallel to the machine front from its substantially vertical position of operation, in which the turbine housing is in upward direction adjacent to the housing for the opening-up roller, and in which the opening-up roller which is coaxially arranged with regard to the spinning turbine extends from above into the spinning turbine.
  • the turbine housing is pivotable about a pivot axis in downward and rearward direction which pivot axis is located behind the spinning turbine at the level of the openingup roller.
  • the pivot angle is limited to 30 because the turbine housing would otherwise hit the withdrawaldelivery system which, in view of the fact that the overall height of the open-end spinning machine is to be held low, follows the spinning turbine at a slight distance relative thereto.
  • the heretofore known pivot system is simple inasmuch as the'removal of the spinning turbine from the opening-up roller extending thereinto is effected during the first phase of the pivot movement.
  • the pivot angle is merely sufficient to clean the opening-up roller or to exchange the same.
  • the necessary accessibility for a quick cleaning of the spinning turbine itself and for a fast exchange of the spinning turbine together with the bearing means therefor is lacking with this pivot system. If it is desired to exchange the spinning turbine or quickly to clean the same, the entire turbine housing has to be removed from the machine which requires considerable time and work. This drawback is also inherent in various other attempts of solving the problem involved.
  • an object of the present invention to provide a pivot system for turbine housings of open-end spinning machines which will make it possible in a simple manner quickly to clean the spinning turbine and to exchange the spinning turbine with the bearing means whenever necessary.
  • FIG. 1 illustrates in side view and partly in section a turbine housing of an open-end spinning machine with a pivot system according to the invention
  • FlGsl showing the turbine housing in its position of operation.
  • FIG 2 is a simplified rear view of FIG. 1 as seen in the direction of the arrow II, but on a considerably larger scale than that of FIG. 1.
  • FIG. 3 is a side view similar to that of 'FIG. 1 with the turbine housing likewise seen in side view and dis placed axially downwardly into a position from which it is subsequently pivoted into the dot-dash position.
  • the pivot system according to the present invention is characterized primarily in that the turbine housing which is pivotable out of the plane of the machine front through the intervention of a connecting element which serves as connecting rod and has one end in spaced relationship to the pivot axis linked to the actuating lever and has its other end linked to the turbine housing, the lever forming with the turbine housing a rigid pivotable unit during the pivoting movements of the turbine housing.
  • the pivot system according to the present invention has various advantages.
  • the housing will be pivoted substantially in a direction transverse to the direction of the axis of thespinning turbine.
  • the spinning turbine will be freely accessible for a quick cleaning and for a quick exchange together with its bearing means.
  • This way of exposing and making accessible of the spinning turbine is effected in a simple manner inasmuch as by means of one actuating lever the turbine housing is first with drawn out of the range of the opening-up roller by a straight line movement and isthen pivoted out of the plane of the machine front.
  • the outward pivoting and the return pivoting of the tur bine housing can be further simplified by pressing the turbine housing in its position of operation by one or more spring means resting against the pivot axis and forming with the turbine housing a pivot unit against the housing of the opening-up roller, while the actuating lever with its crank-forming part and the connecting element linked to the actuating lever and the turbine housing and serving as connecting rod will,following the straigh line adjustment of the turbine housing, be located below the guiding means on the side of the outward pivot movement and will then be located in the region of the outer dead center point of the crank drive.
  • the spring means arrestthe turbine housing in its position of operation on the housing of the opening-up roller. No special manual operation is necessary for the actuation of the arresting system. Theunlocking and arresting is taken care of by the pivoting of the actuating lever.
  • the spinning turbine 3 is by the bearing means 3a received from above and is arrested in the turbine housing by means of a clamping device 4 (not shown in detail).
  • a clamping device 4 (not shown in detail).
  • the turbine housing which is open at the top is arranged adjacent the housing 7 for the opening-up roller 13, while the opening-up roller 13 which is coaxially arranged with regard to the spinning turbine extends into the latter from above.
  • the turbine housing has associated therewith a new pivoting system which in a simple manner permits to expose and make the turbine housing easily accessible so that .a quick cleaning and quick exchange of the spinning turbine with its bearing means will be assured.
  • the turbine housing 3 is pivotable about a pivot shaft 2 which is located within the region below the position of operation of the spinning turbine and is pivotable toward the front out of the plane of the machine front M.
  • a straight line or rectilinear adjustability of the turbine housing with regard to the pivot axis in the direction of the axis of the spinning turbine 3 is provided.
  • l-bolts 5 are rotatably arranged on the pivot shaft 2.
  • the turbine housing 1 is by means of sleeves 5a rectilinearly guided in the direction of the turbine axis on the I-bolts 5.
  • compression springs 6 which press the turbine housing ,1, when the latter occupies its position of operation shown in FIG. ll, against the housing 7 of the opening-up roller l3 and arrests the turbine housing 1.
  • the outward and the return pivoting of the turbine housing 1 including the unlocking and locking on the housing 7 of the opening-up roller 13 is effected solely by pivoting the actuating lever 9 about the pivot shaft 2.
  • the lever is associated with the turbine housing 1 in such away that it is able to effect the straight line adjustment of the turbine housing through the intervention of a crank drive and for purposes of pivoting the turbine housing is arrestable on the crank drive.
  • the crank disc 15 is rotatablyarranged on the pivot shaft 2.
  • a hook serving as connecting rod has one end thereof linked at T6 to the crank disc 15, whereas its other end is linked at 17 to the turbine housing ii.
  • the actuating lever 9 is with regard to the pivot shaft 2 nonrotatably connected to the crank disc 15. At the same time, however, it is pivotable in the direction of the pivot shaft 2.
  • the actuating lever 9 has one end rotatably arranged on a plug sleeve 18 which in its turn is in tangential direction firmly connected to the crank disc 35 by a spacer member 19.
  • the actuating lever 9 is continuously urged to turn relative to the plug sleeve 18 in the direction toward the turbine housing il by means of a tension spring 11 which is located between the actuating lever 9 and the crank disc and which has been omitted in FIGS. 1 and 3 in order not unnecessarily to overload these figures.
  • This arrangement is such that the actuating lever 9 during its pivoting movement from the position shown in FIG. I in counterclockwise direction latches automatically into the recess I2 of the housing.
  • the actuating lever 9 will with regard to the pivot shaft 2 be nonrotatably connected to the turbine housing 1.
  • the actuating lever 9 is pivoted in counterclockwise direction.
  • the turbine housing is rectilinearly adjusted in downward direction along the guiding cams 8 by means of the above mentioned crank drive in the direction of the arrow 2i.
  • the guiding cams 8 act counter to a pivoting moment which acts in the direction of the outward pivoting direction and is caused by the springs 6. This pivoting moment decreases as a result of the movement of the joint point 16 toward the outer dead center point of the crank drive and at the instant when the turbine housing leaves the guiding cams 8 equals zero for all practical purposes.
  • lever 9 During the return pivoting of the turbine housing the actuating lever 9 remains locked in recess 12 until the turbine housing engages a rear abutment which in the specific embodiment shown is formed by the suction head 20. Thereupon, lever 9 is against the force of spring 11 pivoted out of the recess 12 and is pivoted in clockwise direction. Inasmuch as the crank drive first operates in the region of the outer dead center point, spring 6 will during the movement of the turbine housing onto the guiding cams 8 practically not exert a pivoting moment in the outward pivoting direction.
  • an especially advantageous design of the invention consists in adjustably mounting the turbine housing 3 for adjustment in the direction of the axis of the spinning turbine 3.
  • This way of mounting the turbine housing 1 is effected through the intervention of a pivot arm 24 which is cranked around the delivery system 23.
  • the pivot axis is within the region below the delivery system 23 offset with regard to the direction of the axis of the spinning turbine, when the latter is in its position of operation, toward that side which is remote from the plane of the machine front 14.
  • the hook 10 serving as connecting rod is linked to that part 24a of the cranked pivot arm which faces toward the pivot shaft 2.
  • the region below the spinning turbine or spinning turbine housing remains completely freely accessible.
  • a further advantage of the arrangement according to the present invention consists in that with the lateral pivoting the turbine housing is displaced simultaneously in downward direction whereby the turbine housing reaches a level which is even more easily accessible for servicing.
  • Another advantageous design of the invention consists in that the guiding surfaces 8a of the guiding cams 8 arranged on the outward pivoting side (arrow 22) extend parallel to the axis of the spinning turbine 3 when the latter is in its position of operation and parallel to the longitudinal axes of the I-bolts 5.
  • the engaging surface 2a of the suction head 20 for the turbineho'using l is inclined downwardly away from the axis of the spinning turbine 3 when the latter is in its position of operation.
  • the turbine housing l is guided by means of the guiding cams 8 which are arranged on the outward pivoting side.
  • An openend spinning machine which includes: a turbine housing open at its upper end, a spinning turbine journalled in said turbine housing, a housing means for an opening-up roller, said housing means being'arranged above and closing up said turbine housing when said turbine housing is in its position of operation, a'pivot shaft extending in the longitudinal direction of said machine at a level lower than said turbine housing, said turbine housing being movable relative to said pivot shaft from a first position in which said turbine housing is in engagement with said housing means successively along a straight first path in the axial direction of said turbine housing and along a curved second path around said shaft and vice versa, guiding means projecting from said housing means and extending in axial direction of said turbine housing while slidingly engaging a portion of said turbine housing for guiding the same along said straight first path, crank drive means connected to said turbine housing, control lever means connected to said crank drive means and operable to cause said crank drive means to move said turbine housing away from said housing means along said first path and to disengage said turbine housing from said guiding means, and means responsive to
  • a machine according to claim 2 whichincludes spring means supported by said pivot shaft and operable in the position of operation of said turbine housing to press said turbine housing against said housing means, said spring means forming; a pivotal unit with said turbine housing.
  • a machine which includes a suction head arranged adjacent to and having an engaging surface thereof in engagement with said turbine housing when the latter is in its position of operation, and in which at that side of the machine toward which the turbine housing is pivotable said guiding means includes a guiding element having its guiding surface extending substantially parallel to the axis of said turbine housing when the latter is in its position of operation, whereas said suction head surface which engages said turbine housing when the latter is in its position of operation is inclined in a direction away from the axis of said turbine housing when the latter is in its position of operation.
