Definitions

  • the invention relates to a continuous washing machine according to the preamble of claim 1 and a washing method using such a continuous washing machine according to the preamble of claim 16
  • Continuous washing machines work according to the pivoting or rotating washing principle.
  • the laundry is carried on the drum shell or through the middle of the drum.
  • a continuous washing machine is for example from the DE 199 41 073 A1 known.
  • adjacent washing areas are formed as wash chambers, which are defined by disc-shaped partitions, which are arranged in the drum perpendicular to the longitudinal axis of the drum and are welded with their outer edges to the drum.
  • central circular openings are provided in the partitions, preceded by a respective scoop-like installation is, which also includes a separating plate.
  • the laundry items When rotating the drum in the washing operation, the laundry items are raised at each drum rotation by means of a Mit Psycho- or separating plate and then dropped from above into the treatment liquid in this prior art. If the direction of rotation of the drum is reversed for the purpose of conveying the laundry items to the next washing chamber, the laundry and at least a portion of the treatment liquid are fed by means of the blade-like installation to the opening in the dividing wall and from here to the washing chamber adjacent in the conveying direction.
  • a disadvantage of this known continuous washing machine is that the material, in particular the many meters long drum is subject to a high mechanical load, with the existing straight, flat partitions lead to any increase in the strength of the drum.
  • the high mechanical load further requires a comparatively large material thickness of the drum, which leads to an increased production costs and on the other hand to an increased energy expenditure in the drive of the drum.
  • Another disadvantage of the known continuous washing machine is that during transport of the laundry items from one chamber to the adjacent chamber through the opening or the transport channel in the corresponding partition wall through the risk of clogging of the opening occurs.
  • This clogging hazard is significant given that the drum typically has a plurality of wash chambers one behind the other in the longitudinal direction of the drum, and therefore the laundry items must be passed through a plurality of apertures in a single pass through the system.
  • the drum and spiral are rotated by 360 °, whereby the laundry items lying in the treatment liquid, together with the treatment liquid, are transported further in the conveying direction by a distance corresponding to the width of a washing chamber, in accordance with the known mode of operation of a screw conveyor.
  • the drum and coil is intermittently in one direction and in the other direction, ie moved back and forth and thereby generates the required washing mechanism.
  • the drum is structurally particularly stiffened so that lower material thicknesses are sufficient to obtain the required strength.
  • the invention has for its object to provide a continuous washing machine, which is particularly stable mechanically, are largely avoided in the blockages during the conveyance of laundry and still can wash rotating. Also, a washing method suitable for this washing machine should be created.
  • the basic structure a screw conveyor or an Archimedean helix provided, on the other hand, however, when the system operates in the washing mode, a further transporting the laundry items in the axial direction is suppressed by the entrainment, so that during a washing cycle always washed in the same washing area, although the drum and spiral continuously turns.
  • the continuous washing machine according to the invention is distinguished by great stability, having basically been constructed on the principle of a screw tube conveyor in which the screw or coil arranged in the drum and connected to the drum mechanically stabilizes the overall construction, so that due to a relative lightweight construction yet the required mechanical stability can be achieved and in operation a comparatively low drive energy is sufficient.
  • the risk of clogging due to the transport of the laundry items in the conveying direction from chamber to chamber can be virtually eliminated after the laundry items no longer have to be transported through openings in the chamber walls (the transport channel), but rather along the aisle Worm or helix be transported over a shovel.
  • the laundry items and the liquor are lifted during the washing operation of the blade-like entrainment and dropped from above back into the same wash chamber.
  • the fabric of the laundry is flowed through by the processing liquid, since this the Fabric leads and the laundry then falls into the processing liquid.
  • the fibers of the fabric are stretched and compressed, which promotes the passage of the tissue.
  • the continuous washing machine according to the invention can advantageously be operated in the washing mode, either rotating or reciprocating.
  • the laundry is conveyed on the one hand by means of the coil in the conveying direction and on the other hand first raised by means of the entrainment device and then dropped on further rotation of the drum of the entrainment device down.
  • the treatment liquid can basically take the same route.
  • washing operation As far as in the foregoing and hereinafter of "washing operation”, “washing area”, “wash chamber”, etc. is mentioned, this includes other in a washing machine of the type in question here usually occurring treatments to subsume, so in particular also the rinsing and, if necessary also the equipping, so that in particular also a “rinsing operation”, “rinsing area”, “rinsing chamber” etc. should be included.
  • An otherwise not shown continuous washing machine comprises a cylindrical drum 2 or inner drum 2, which is driven about its longitudinal axis 4 by means of known per se and therefore not shown drive means either in one of the two possible directions of drive.
  • a screw 6 or coil 6 is arranged, for. B. may consist of folded sheet metal and connected to its outer spiral outer edge 8 with the inner wall of the drum 2, in particular welded.
  • the coil 6 has not shown here, extending in the radial direction Wendelabkantepteptept or reinforcing ribs.
  • the arrangement of rotatably mounted drum 2 together with arranged therein and with the drum 2 rotatably connected helix 6 corresponds to that of a screw tube conveyor.
  • the laundry items to be treated are in the drum 2 in a manner not shown in the illustration according to Fig. 1 entered from the left, for example by means of an input funnel and the treated laundry items are in also not shown manner in the illustration according to Fig. 1 transported to the right, for example by means of a discharge chute from the continuous washing machine and then fed, for example, a dewatering device, such as a dewatering press.
  • a dewatering device such as a dewatering press.
  • each washing chamber 12 a driver 14 is arranged in the form of a driver plate 14, which among other things serves to take the laundry items in rotation of drum 2 and coil 6 in the washing operation, ie lift, etc., see. further down.
  • Each driver plate 14 is laterally fluid-tightly connected to the adjacent coil sections 10, in particular welded, and extends from an approximately central position between the longitudinal axis 4 and inner wall of the drum 2 to the outside to the inner wall of the drum 2, with which it also fluid-tight manner, in particular is welded.
  • Each driver plate 14 is helically curved about the longitudinal axis 4, as in particular from Fig. 2 becomes clear, wherein the radius of curvature increases with respect to the longitudinal axis 4 from the inside to the outside. All driver plates 14 are preferably aligned within the drum 2 in each case in the same orientation.
  • the laundry possibly together with the treatment liquid, is conveyed in the longitudinal direction 4 of the drum from one washing chamber 12 to the adjacent washing chamber 12 , as corresponds to the usual operation of a screw tube conveyor.
  • the laundry items are additionally increased by means of the driver plate 14 during rotation in addition to an increasing extent and finally fall over the free edge of the driver plate 14 down to the bottom of that wash chamber 12 which is adjacent to the previous original wash chamber 12.
  • the drum 2 is driven continuously in the direction of rotation C. It started from the situation according to Fig. 3a ,
  • the treatment liquid 20 has in the chamber 12 at the bottom of the Drum 2 collected, the laundry items 22 are or float in the treatment liquid 20.
  • the driver plate 14 is disposed substantially above the treatment liquid 20 and the laundry items 22.
  • the drum 2 In conveying mode according to Fig. 4a to 4e the drum 2 is rotated a single time by 360 ° in the direction of rotation B. It can be assumed, for example, of the in Fig. 4a shown angular position of the drum 2, the one according to Fig. 3a or Fig. 3e equivalent. In this position, the treatment liquid 20 has collected in the chamber 12 at the bottom of the drum 2, the laundry items 22 are or float in the treatment liquid 20 and the driver plate 14 is disposed substantially above the treatment liquid 20 and the laundry items 22.
  • a delivery cycle is hereby completed, the laundry items 22 together with associated treatment liquid 20 have been promoted in the conveying direction A by a washing chamber 12 in the adjacent washing chamber 12 and a new wash cycle can begin.
  • a pivoting washing operation as in the case of the prior art described above is possible, in which therefore the drum during the washing operation is pivotally moved back and forth, wherein the pivot angle during the washing operation may be about 180 °, preferably 180 ° +/- 45 °, more preferably 180 ° +/- 30 °, in particular 180 ° +/- 15 °; particularly preferred is an angle of 180 ° +/- 5 °.
  • the free treatment liquid 20 may also be drained through a perforated drum shell area over a double drum and the items of laundry 22 then "dry", i. be transported without treatment liquid 20 in the next washing chamber or washing area.
  • the continuous washing machine according to the invention thus also makes it possible to transport the laundry items 22 through the drum 2 without treatment liquid.
  • the helix 6 can expediently possibly also be perforated so that a countercurrent can be passed through the helix 6, in particular rinsing in countercurrent can take place.
  • Fig. 5 It becomes clear how the design and operation of the system can be further optimized by providing various ribs. It is understood that the number of ribs to be provided and their exact positioning in Fig. 5 is shown for example only and can be deviated from.
  • a rib 18 (per washing chamber 12) formed on the driving plate 14 which extends substantially in the longitudinal direction 4 of the drum 2
  • the at least one rib 18 on the driver plate 14 is arranged in the region of the space 16 (see. Fig. 3a ) to allow the laundry 22 to slide more slowly from the driver plate 14 and to pull apart more, thus ensuring an increased degree of stretching and compression of the laundry during the washing process, thereby further increasing the washing quality.
  • the rib 18 may be placed on the driver plate 14, for example, be welded thereto or be folded into the driver plate 14.
  • the preferably a plurality of ribs 24 on the inner wall of the drum 2 are provided in particular for the purpose of producing even more washing mechanics, in particular also in the case of pivoting washing, ie in the case in which the drum 2 of the continuous washing machine in the washing operation back and forth going pivotal movement performs.
  • the ribs 24 may be welded to the inner wall of the drum 2, for example.
