Definitions

  • the invention relates to a lot washing machine with the features in the preamble of the main claim.
  • a lot washing machine with a double-shell washing drum is known, in which the inner cylinder is suspended in several chains and driven in rotation.
  • the lot washing machine is designed as a walk-through washing machine, in which several wash compartments are defined in the inner cylinder by bulkheads, which are filled with different lye and through which the laundry was carried out step by step. is exercised.
  • helical conveyor ribs are arranged in the inner cylinder, which move the laundry over the bulkheads when the cylinder is rotated accordingly.
  • the inner, moving cylinder is surrounded by an outer, standing cylinder, or a half-shell, which form a space between them, which is divided into sections according to the washing compartments and in which the various washing liquors are located.
  • the inner cylinder is perforated at least in its lower area, so that the wash liquor also reaches its interior.
  • Lot washing machines with two-shell washing drum have the best washing effect, but pose problems with the bearing of the rotating inner cylinder.
  • the chain has to be led through the area of the wash liquor, which impairs chain lubrication and leads to a considerably shorter service life of the chain.
  • DE-OS 25 27 502 solves this problem with a special seal, which, however, is insufficient in practical operation Shows results.
  • the invention is therefore based on the object to show a possibility for a simpler and more reliable storage and drive option for the rotating cylinder.
  • the invention solves this problem with the features in the characterizing part of the main claim.
  • the solution according to the invention can be used for all types of batch washing machines, irrespective of whether the washing drum has one or two shells.
  • This exclusively end-side storage with a directly adjacent drive has the advantage that the concentricity of the driven and appropriately stiffened cylinder is ensured at the points where it is ultimately needed.
  • feed and removal devices for the laundry reach into the interior of the cylinder, against which the cylinder is now in perfect alignment.
  • the bearings and drive act directly on the outside of the rotating cylinder.
  • the inner cylinder protrudes a bit beyond the outer fixed cylinder and is supported and driven on it by rollers.
  • the Drive can be made in any way according to the invention in both cases.
  • a gear drive, a friction wheel drive or the like is also possible.
  • the chain only has drive tasks, which increases the operational safety and service life of the chain drive.
  • the invention also enables an inexpensive construction, since the ring flange according to the invention combines the guideway and drive track.
  • a sealing arrangement according to the invention which has an independent character and can also be used in other washing machines. After the two cylinders in the washing area are no longer supported against one another, the sealing arrangement according to the invention can also be used there for the absolutely clean separation of the washing liquors. This is particularly important for the implementation of washing processes in which there is a risk of color spreading due to the mixing of the liquor, which will lead to undesired dyeing of the laundry.
  • the elasticity of the sealing arrangement is advantageous, which compensates for any offset of the inner cylinder with respect to the outer one.
  • a fresh water counterflow can be directed into the free space between the two cylinders via the flood chamber, which ensures that no solid particles (sand, needles etc.) come to the sealing lip.
  • the sealing arrangement according to the invention has the particular advantage for the lot washing machine according to the invention that the two cylinders are also in their End areas do not need to have gradations for sealing purposes, but can just go through. This has advantages for the mechanical stability of the machine and allows the construction of inexpensive cylinders.
  • Fig. (2) is an end view of the
  • Fig. (3) is an end view of the
  • Fig. (4) shows a cross section through a seal arrangement at the cylinder end.
  • Fig. (1) shows a lot washing machine (1) with an inner rotating cylinder (2) and an outer, in a frame (14) fixed cylinder (3).
  • the interior of the two cylinders (2, 3) is formed in the washing area in a manner known per se, by forming washing compartments in the inner cylinder (2) by Schott, in which different washing liquors are located.
  • the inner cylinder (2) is moved back and forth for the washing process.
  • the inner cylinder (2) rotates through a larger angle, as a result of which the helical conveyor ribs arranged on the inside come into operation and convey the laundry via the bulkheads into the next wash compartment.
  • the next wash cycle then starts with a reversing cylinder movement.
  • the details described are in the Drawings not shown.
  • the inner cylinder (2) is designed as a self-supporting tube and is only supported at the two ends (4, 5). Intermediate storage does not need to take place even with longer cylinders (2) if the tube is suitably rigid.
  • the inner cylinder (2) protrudes a little above the outer cylinder (3) (see Fig. (4)).
  • the bearing and drive act on this protrusion (23).
  • funnels or similar means for filling and ejecting the laundry are arranged in a manner known per se.
  • the inner cylinder (2) is driven only at one end (4).
  • the drive can also be provided at the other end (5) or as a double drive at both ends (4, 5).
  • a stepped ring flange (10) is attached to the end (4) of the inner cylinder (2), which rotates with the cylinder (2).
  • the ring flange (10) has an annular groove (11) and next to it a higher gear rim (12).
  • Bearing rollers (6, 7) engage in the annular groove (11) and are arranged at the ends (4 and 5) on supports (15) in the frame (14).
  • the rollers (6, 7) only support the inner cylinder (2) from below in the exemplary embodiment shown (compare FIGS. (2 and 3). In other embodiments, a larger number of bearing rollers can be provided, which also surround the inner cylinder
  • the annular groove (11) is designed as a radial and axial guide for the engagement of the bearing rollers (6, 7).
  • the ring flange (10) at the other end (5) is thus designed as a simple bearing ring without a ring gear (12) and without an axially leading annular groove (11).
  • a chain drive (8) is provided for driving the inner cylinder (2), which chain has an endless chain (9) which engages with the ring gear (12) in the upper cylinder region.
  • Four motors (13) are provided for the chain drive, which are designed as electrical plug-in motors and are mounted at the foot of the frame (14). It is driven by two chain sprockets (16), each of which drives two of the small-sized motors (13).
  • the chain sprockets (16) are arranged such that the chain (9) is guided straight over the sprocket (12) at a 180 wrap angle and between the chain sprockets (16).
  • the cylinders (2, 3) are designed as straight, aligned tubes. At the overhang (23), this means that the free space (21) between the two cylinders (2, 3) filled with wash liquor is sealed axially.
  • the inner cylinder (2) is perforated only in the washing area up to this sealing arrangement, but not in the area of the protrusion (23). Sealing takes place via an axial, ring-shaped disk seal (18) which is flanged to the outer cylinder (3).
  • the disc seal (18) is designed as a rigid part that resists the water pressure and leaves a small gap to the inner cylinder (2).
  • the disc seal (18) works together with an elastic lip seal (17), which above all has a radial sealing effect.
  • the lip seal (17) is designed as an end sealing tape and releasably arranged on the lying leg (26) of an annular, on the protrusion (23) fixed angle flange (25).
  • the lip seal (17) rotates with the cylinder (2).
  • the lip seal (17) presses against an S-shaped chamber flange (22) which is attached to the stationary outer cylinder (3).
  • a flood chamber (19) is formed between the two services (17, 18), the overhang (23) and the chamber flange (22).
  • the chamber flange (22) has a water connection (20) in the form of a nozzle through which fresh water can be fed from the outside into the flood chamber (19), which through the gap to the cylinder (2) via the screen seal (18) into the free space (21) can flow and by this counterflow prevents coarse contaminants from reaching the sealing lips.
  • wash liquor emerging in small quantities via the window seal (18) and the small gap can also be collected in the flood chamber (19) and discharged through the stationary connection piece (20).
  • a further collection chamber can be formed behind the lip seal (17) through the chamber flange (22), from which, if the lip seal (17) fails, any escaping lye can be collected in a controlled manner via a drain (24).
  • the chamber flange (22) thus acts at its end together with an annular web (28) which is welded as a radial web into the jacket of the metallic cylinder (2).
  • the angle flange (25) and the ring flange (10) are screwed together, which must not have a snug fit on the cylinder (2).
  • the sealing arrangement of the disk seal (18), flood chamber (19) and lip seal (17) can also be arranged in the interior between the two cylinders (2, 3) at the level of the bulkhead separating the washing parts. As a result, the free space (21) is sealed so that the wash liquor can no longer get from one compartment to the other.
  • the washer seal (18) is in turn flanged with a small gap to the cylinder (2) on the outer cylinder (3).
  • the sole use of the disc seal (18) can be sufficient.
  • the lip seal (17) is detachably attached to the cylinder (2) at a distance from the disk seal (18), which is preferably achieved by a taped sealing tape.
  • the lip seal (17) can press directly against the wall of the outer cylinder (3) or against an annular flange attached there.
  • the lip seal (17) is preferably applied radially, so that in the embodiment of FIG. (4) the lip seal (17) experiences an additional contact pressure due to the liquid pressure that may occur in the flood chamber (19) due to its curved shape.
