Definitions

  • ABSTRACT Fore'gn Apphcatlon Pmmty Data A treating apparatus for continuously traveling webs, Aug. 7, 1971 Gennany P 21 39 651.0 such as textile webs washed has a drum about which the web is partially wrapped while immersed in U-S. Cl. a and is radially oscillated through an cc- Cl.
  • This invention relates to a traveling web treating ap- Iparatus having a horizontal drum which rotates in a liquid bath container containing liquid at a level above the axis of the drum, the web being partly wrapped around the drum for immersion in the liquid, and the drum being rotative while being radially oscillated at a frequency sufficiently high to exert an agitating or substantially vibrating effect on the web.
  • the drum In the case of certain delicate textile fabrics, and per haps in all instances when textile webs are being treated by the apparatus, it is desirable to have a means for rotating the drum by the use of rotary power other than that effected by relying on the frictional drive the web exerts on the drum. If the drum is rotated by power other than that exerted by the traveling web, the drive should preferably .be variable as to the rotative speed given the drum to avoid overdriving or underdriving the web, and any shaft which must pass through the containers walls should rotate concentrically about its axis to avoid shaft sealing difficulties.
  • the object of the present invention is to provide a simplified apparatus which avoids such sealing problems, and which will permit the drum to be driven rotatively as required for its periphcry to be synchronized with the speed of the traveling web.
  • a liquid bath container having an end wall in which an opening is formed below the level of the bath, a rotative drive shaft extending through this opening from the outside of the container to the inside, with bearing means on the outside of the container for radially rigidly mounting this drive shaft for concentric rotation and, of course, means on the outside of the container for rotatively driving this shaft but without radial oscillation motion. Since the shaft rotates simply concentrically, sealing means are easily provided for sealing the shaft fluid-tightly with respect to the opening in the container end wall.
  • the drum On the inside of the container the drum has the tubular axle which is parallel to the shaft, the latter and the axle having longitudinally opposed ends.
  • the drum s axle is held parallel to the shaft by a coupling means inside of the container which eccentrically connects the two opposed ends in a manner that is substantially rigid in a radial direction so that relative rotation of the shaft produces the radial oscillation of the axle and drum, but in a rotative direction the coupling operates in the manner of a plain sliding journal and bearing assembly, as contrasted to the prior art concept of reducing friction to a minimum by the use of antifriction bearings.
  • These bearing assemblies may be tightened and loosened as to their relatively sliding surfaces so that the degree of rotative force imparted to the drums axle may be varied. The action is somewhat like that of a slipping clutch having its slippage controllable so that varying degrees of rotative force may be applied to the axle.
  • shafts at opposite ends of the container are synchronized and timed relative to each other so that the axis of the drums axle always remains parallel to these shafts.
  • FIG. 1 is a perspective view of a textile web washing apparatus embodying the features of the present invention
  • FIG. 2 is a longitudinal vertical section, a part of the shaft being in elevation, showing the shaft and its journal's and the coupling between this shaft and the drums axle;
  • FIG. 3 in a very schematic manner illustrates how the action of the frictional drive may be made automatically responsive to the tension on the web whereby to eliminate manual adjustment of the frictional drive;
  • FIG. 4 shows the parts of FIG. 3 rotated enough to illustrate the eccentricity involved.
  • FIG. 2 illustrates only the elements at the left-hand end of FIG. 1, there being a duplicate (not shown) at the right-hand end.
  • FIG. 1 shows a liquid bath container 1 having an end wall 2 in which an opening 3 is formed below the level of this bath, the latter being indicated at 4 as being near the open top of the container 1.
  • a rotative shaft 5 extends through the opening 3 from the outside of the container 1 to its inside.
  • the bearing means on the outside of the container which radially rigidly mounts the shaft 5 for concentric rotation comprise interspaced antifriction bearings 6 and 7, these hearings being mounted by the inter.-
  • the forarninous or liquid pervious drum 11 has its end wall 13 mounted by the drums tubular axle 14 which is on the inside of the container.
  • the tubular axle 14 contains a conical female part 15 that is nonrotative and concentric relative to the axle 14.
  • This end of the axle 14' is opposed to the end of the shaft 5 and the latter mounts a conical male part 16 which fits the female part 15 in a rotatively sliding manner, this male part 16 being non-rotative and eccentric relative to the shaft 5.
  • the part 16 is non-rotatively connected to a stub shaft 5a which may be an integral part of the shaft itself.
  • the stub shaft 5a is externally cylindrical but is eccentric with respect to the balance of the shaft 5 and the conical male part 16 is axially slidable on this stub shaft 5a, a pin 17 locking the part 16 nonrotatively with respect to the stub shaft 5a, but in an axially slidable manner.
  • the shaft 5, including its stub shaft 5a, has an axially extending bore 18 which is concentric with respect to the axis of the shaft 5 and a push rod 19 extends through this bore with an inner end bearing against an end plate 16a of the conical male part 16, its outer end receiving variable pressure or position adjustment by a screw 20 threaded through a hole in an outer end cap 21 connected to the outer one of the walls 8.
  • An antifriction thrust bearing 22 is interposed between the inner end of the screw 20 and the outer end of the push rod 19 since the screw 20 is non-rotative excepting when being adjusted,
  • the conical parts 16 serve to mount the axle 14 and that in a radial direction these parts are substantially rigid so that rotation of the shaft 5 can impart the desired radial oscillation or vibration to the axle 14 and thus to the drum 11, but that rotatively the parts 15 and 16 form what is in effect a plain sliding rotary bearing. Actuation of the screw to release the pressure on the two parts 15 and 16 can provide for substantially free rotation of the axle 14 relative to the shaft 5 when desired, in which case the apparatus would function more or less in the manner of the German Patent No.
  • the drum rotation can be peripherally synchronized with the traveling speed of the web.
  • a bearing liner 23 in the form of a conical cap fitting the conical part 16 is provided.
  • the conical parts would normally be made of metal, and this bearing liner 23 when made of fiberglass reinforced plastic, particularly polytetrafluorethylene as the plastic, provides a smooth sliding action avoiding possible jerkiness or roughness on the part of the rotative force imparted to the axle 14 when the screw 20 is tightened as required to apply the proper rotative force to this axle l4 demanded by the fabric being washed or otherwise treated.
  • the bearing parts are, of course, immersed in the liquid bath. As shown by FIG. 1, the fabric web W is wrapped partially downwardly and around and upwardly and from the drum 11 by guiding rollers 24.
  • the entry and exit of this web W is smooth with the web traveling continuously although it is agitated by the radial component of the drum 11 while the web is traveling through the bath 4.
  • the bearing liner 23 assists appreciably in promoting the smooth rotation of the drum and, therefore, the travel of the web W without the latter necessarily driving the drum 1 1 rotatively, although it may if desired.
  • the web W receives tension or a continuous pull in the direction of the arrow 25 to keep it traveling, in the normal use of an apparatus of the present type.
  • the seal assembly 10 may be designed simply because the shaft 5 rotates concentrically, and it is retained by a housing 2a fixed to the drum 2, this being done by compression of the housing 20 through the medium of compression bands 24 which when loosened permit the sealing assembly to be moved to the left in FIG. 2.
  • the bearings 7 are retained in position by one or more set screws 7a, for example, and the end cap 21 is fastened to the outer one of the walls 8 by screws 21a. Therefore, release of the bands 24, of the set screw or screws 7a, and the screws 21a, permit the shaft 5 to be moved to the left far enough for the conical part 16 to move outwardly through the hole 3 and permit the complete separation of the two conical parts. This permits the drum 11 to be removed from the container 1 so that the bearing liner 23 may be serviced or replaced.
  • the two shafts 5 at the opposite ends of the apparatus are synchronized by an interconnecting drive shaft DS which extends transversely from one side of the machine to the other and interconnects the shafts 5 for synchronized and properly timed rotation through chain drives 26.
  • This shaft DS is driven by a suitable motor (not shown) located on the outside of the bath container or tank 1.
  • the screw 20 is replaced by a reciprocative plunger 20a to which pressure is applied by an electric solenoid 27 powered by a suitable source 28 of electric current and a circuit under the control of a rheostat 29.
  • This rheostat is shown as having its movable element actuated by a roller 30 working on a span of the web W leaving the exiting one of the rollers 24 with its other span end formed by another guide roller 24a, the roller 30 being pressed into this span by a spring 31.
  • the roller 30 rises and the resistence of the rheostat 29 is reduced so that the solenoid 27 through the part 20a applies greater pressure to the push rod 19, loosening of the span producing the opposite effect. In this way the frictional drive between the conical bearing parts previously described may be made automatically responsive to the tension on the web pulled from the apparatus of FIG. 1.
  • FIG. 3 is entirely schematic and is intended only to show the principal of operation involved in providing the push rod with a remote control made automatically responsive to the tension of the web to assure that the proper driving force is frictionally applied to the drum 11 at all times.
  • An apparatus including a web treatment drum in a fluid bath container having an end wall in which an opening is formed below the level of this bath, a rotative shaft extending through said opening from the outside of said container to its inside, bearing means on the outside of said container for radially rigidly mounting said shaft for concentric rotation, means on the outside of said container for rotatively driving said shaft, seal ing means for sealing said shaft fluid-tightly with respect to said opening, an axle mounting said drum and extending parallel to said shaft on the inside of said container, said shaft and axle having mutually opposed ends, and coupling means inside of said container for eccentrically interconnecting said ends substantially rigidly in a radial direction and frictionally in a rotative direction.
  • said coupling means includes a plain sliding journal and bearing assembly formed by conical male and female parts respectively connected non-rotatively to said opposed ends with the part on one of said ends eccentric with respect thereto and the part on the other of said ends substantially concentric with the latter.
