Definitions

  • the invention relates to a treatment device of the type corresponding to the preamble of claim 1.
  • Such a treatment device is known from DE-PS 690 530.
  • a plate is resiliently arranged above the level of the treatment liquid, on which a vibrator with circumferential eccentric is arranged and from which bearing plates extend downward, on which the drum is mounted in the treatment liquid.
  • This embodiment cannot be used in practice because the vibrations generated by the vibrator on the spring-loaded plate are not well defined and it cannot be prevented that the drum oscillates back and forth in the container in an undesirable manner.
  • the invention has for its object to develop a generic device so that no sealing problems occur and a defined vibration of the drum is guaranteed.
  • the eccentric bearing therefore no longer acts on the shaft of the drum, but on the bearing plate above the liquid level. It is therefore no longer necessary to seal the eccentric shaft because it is not in the liquid.
  • the torque arm helps against uncontrolled vibrations of the drum and the end shields, so that the end shields are guided desmodro isch.
  • the container therefore nestles as close as possible to the drum or the spatial area circumscribed by it during its oscillating movement.
  • At least three support rollers are provided on the end shields on bearing journals firmly connected to them, which therefore e.g. form a three-point bearing for the drum.
  • Such a roller chain can have the support rollers between double-sided link chains.
  • a preferred embodiment is, however, given in claim 6.
  • the outer rollers serve only to support the support surface
  • the inner rollers only serve to support the drum.
  • the drum is freely rotatable and is carried along by the web moving forward. In special cases it can be useful to drive the drum.
  • the drum can also be mounted on ring bearings provided at each end on the end shields (claim 10).
  • Rolling bearings are meant whose radial extension is small in relation to their diameter (so-called thin ring bearings).
  • Both end shields are mounted on an eccentric.
  • the configuration according to claim 11 is recommended.
  • the torque arm can be Say 12 reproduced way to be realized constructively.
  • the abutment forms a fixed point to a certain extent, which prevents the rotation of the bearing plate around the eccentric, but still permits the displacement of the bearing plate caused by the eccentric movement.
  • the feature of claim 13 results in the greatest distance of the torque arm from the eccentric and thus the lowest forces on the torque arm.
  • the drum should support the web as completely as possible, but should not hinder the flow through the web. In an embodiment that comes into consideration for this purpose, it can be designed according to claim 16.
  • Fig. 1 shows schematically the principle of the invention seen in a first embodiment as a vertical section perpendicular to the drum axis against a bearing plate;
  • FIG. 6 shows a side view of a concrete embodiment of the treatment device
  • FIG. 7 shows a partial view according to FIG. 6 from above
  • FIG. 9 shows the area framed by dash-dotted lines in FIG. 8 on an enlarged scale, cut in the vertical central plane.
  • the treatment device 100 indicated in FIG. 1 is used for wet treatment of a textile fabric web 1 in a treatment liquid 4 located in a container 2 up to a level 3.
  • the container 2 is held in a machine stand (not shown) in which a rotating driven eccentric shaft 5 is also stored above level 3 of the treatment liquid is.
  • eccentrics 6 are arranged at both ends of the container 2, on each of which a bearing plate 10 is mounted, which is sealed within the end face of the container 2 parallel to the plane of the drawing in FIG. 1, that is to say in the treatment liquid 4 is arranged.
  • the bearing plate 10 has the outline shown in FIG. 1 and is suspended in the embodiment of FIG. 1. When the eccentric shaft 5 rotates, the eccentric 6 causes the bearing plate 10 to oscillate back and forth.
  • an abutment 7 in the form of a roller 7 'or a corresponding sliding block on the bearing is at the lower end thereof shield 10 are mounted, which are guided between two mutually parallel guide surfaces 8 fastened in the interior of the container 2 on its end faces.
  • the abutment 7 and the guide surfaces 8 together form a torque support 9, which leads to the fact that the bearing plate 10 is completely positively guided during the movement of the eccentric 6.
  • Two end shields 10 are arranged opposite one another in close proximity on the inside of the two end faces of the container 2.
  • the drum has rings 21, on which the support rollers 11, 12, 13 rest and roll from the outside and which are connected to one another by axially parallel rods 22 which are arranged close together in the circumferential direction on a pitch circle and which form the drum circumference and consist of pipes.
  • the drum 20 is thus mounted on the support rollers 11, 12, 13 on the end plate 10 in the middle.
  • the bearing plate 10 has a circular opening 14, through which a tubular closed displacement body 15 extends, which is tightly connected at its end faces to the end faces of the container 2. There is no treatment liquid 4 in the interior of the displacer body 15. Rather, there remains only the cross section of the container 2 located outside, the outer circumference of which is designed such that the wall of the container perpendicular to the plane of the drawing in FIG. 1 faces the bearing shield 10 nestles as close as possible without the bearing plate 10 abutting in its movement caused by the eccentric 6. From this point of view, the diameter of the opening 14 is chosen to be a certain amount larger than the outer diameter of the displacer body 15, which is otherwise as large as possible, so that it just barely bumps into the eccentric drum 20 fits.
  • deflecting rollers 16, 17, which are parallel to the drum axis, are fixedly mounted on the end faces 2 'of the container 2, over which the web 1 is guided in the manner shown in FIG. 1, so that it wraps around the drum 20 almost entirely .
  • the drum 20 performs a defined displacement perpendicular to its axis, which is communicated to the web 1 wrapped around the drum 20 and ensures a strong relative movement between the web 1 and the treatment liquid 4.
  • the deflection rollers 16, 17 do not follow the eccentric movement of the drum 20.
  • the material web 1 is thus moved with the drum 20, held on the deflection rollers 16, 17. In between, the web runs a short distance. This results in a forced movement of the web 1 through the treatment liquid 4 in the transition areas and an increase in the washing effect. Trials have shown that good to extraordinary results are obtained in shrinking processes. Insofar as elements corresponding to the elements of FIG. 1 are present in the other figures, the same reference numbers are used.
  • the arrangement of the eccentric 6, the drum 20 ′′ and the torque support 9 is the same as in the treatment device 100 of FIG.
  • the circumference of the drum is surrounded at most of its circumference at a constant radial distance by a circular support surface 24 which is formed by a correspondingly shaped guide rail and which is fastened to the bearing plate 10 ′′ and at the top one Interruption 26 has.
  • the drum 20 ′′ is mounted on the end shield 10 ′′ via a roller chain 25, which replaces the individual support rollers 11, 12, 13 of the preceding embodiments and whose rollers 30 are on the one hand on the circular support surface 24 and on the other on the outer circumference of the drum 20 ′.

  • the circular support surface 24 has the upper interruption 26 in an angular range of approximately 30 ° to 60 °, in the exemplary embodiment 40 °, through which the roller chain
  • Bearing plate 10 '' driven chain sprocket 27 can loop around. In this way, the drum 20 ′′ can not only be supported by the chain 25, but also driven, while the drums 20 and 20 ′ of FIGS. 1 and 2 can be freely rotated and are carried along by the web 1.
  • FIG. 4 shows a first embodiment of a roller chain 25, which consists of a conventional duplex link chain 28, which carries rollers 30 on both sides on elongated pins 29, the diameter of which is greater than the height of the links Link chain 28 is and which will generally consist of plastic.
  • the rear rollers 30 in FIG. 4 roll on the circular guide surface 24, the front rollers 30 on the circumference of the drum 20 ′′.
  • FIG. 5 shows an alternative roller chain 25 ', in which a duplex link chain 28 is again present, but in which the rollers 30 are arranged between the two link strands.
  • the end of the drum 20 ′′ must extend axially as far as the area of the circular guide surface 24.
  • a treatment device 100 corresponding to FIG. 1 is shown in more detail in FIGS. 6 to 9.
  • the treatment device 100 comprises a machine frame screwed together from profiled beams, which comprises at each end an essentially flat frame 41 with two upright supports 42 which are juxtaposed with a transverse spacing and which are connected at the top by a cross member 43 and at the bottom by a cross member 44.
  • the frames 41 present at the front ends of the treatment device 100 are in turn connected to one another by intermediate carriers 45 to form a spatial structure.
  • the drum axis runs perpendicular to the planes of the frame 41.
