DE2308259A1 - Washing machine unloading process - with press to extract water before laundry is dried and ironed - Google Patents

Abstract

The washing machine discharges the laundry continuously or intermittently into the unloading unit which, synchronised by the action of the press, pivots to pass the wet clothing into the press. The max. vol. of residual water is extracted before the laundry passes to drying and further processing to reduce the water vapour generate in tumble drying so that the laundry has a consistent humidity level.

Description

Unloading device for continuously or discontinuously operating washing machines and dishwashers for washing textile fabrics, eg washing " The invention relates to washing machines and dishwashers which operate continuously or discontinuously for washing and rinsing textile sheets, such as ash, which are hereinafter referred to as washing tubes for short. These washing tubes are components of so-called ash lines, on which ash is washed, bleached, rinsed, dehydrated and pre-dried in a way that is insufficient or ready for press. The known ash tubes are loaded continuously or discontinuously. This is followed by washing, bleaching and rinsing.

The discharge of the treated laundry also happens more or less continuous or discontinuous. Above an unloading or output belt the treated laundry is fed into a continuously operating continuous drainage press, hereinafter referred to as squeezing for short, and then one continuously for pre-drying or discontinuously operating shakers or tumblers.

This method of operation has the consequence that the one treated in the washing tube ash is not always optimally dehydrated mechanically0 For this reason, considerable Additional amounts of water can be evaporated in the tumbler.

If the evaporation of the oo g occurs. Amounts of water in continuously working Tumblers, so-called continuous dryers, then the distribution of the Do not always wash the residual moisture evenly after pre-drying However, uneven distribution of the residual moisture causes considerable work disruptions in the finishing departments, e.g. Bo in the fishing room.

If the evaporation takes place in batch-wise tumblers, then the distribution of the residual moisture remaining in the laundry is better, but the shower, which is not always optimally drained mechanically, turns into a sloping one Noticeable tumbler performance, This is where the idea of the invention comes in. The aim of the invention is to provide continuously or discontinuously operating ash lines - ;, iJaschmaschinen, so-called Wash pipes, to enable optimal mechanical drainage of the bag treated in the washing tube, punch presses or cyclic dewatering presses operate in batches to be able to use0 The object of the invention is achieved in the place of the known Unloading or output belts an unloading device is created. This unloader is both the performance of the washing tube and the performance and shape of the batch working punch or cycle dewatering press adapted.

The unloading device takes the cycle time of the batch working punch or cycle n-dewatering press incurred or transported out sia amounts of the vva tube, but also has an overflow at the same time in the discharge device to reuse the water washed in with the wash to be able to.

The unloading device is batch-wise according to the cycle time working ram or cycle dewatering press, for a short time either for unloading lifted mechanically, pneumatically or hydraulically and so the laundry washes away with it water in the ram or cycle drainage press. Then the unloading device goes back to their starting position until the beginning of the following work cycle.

The invention achieves that with continuous or discontinuous working wash tubes through the use of batch-wise working punches or Cycle dewatering presses provide optimal mechanical dewatering of the washed and rinsed washing can be done. Due to the previous optimal mechanical Dewatering in a punch or cycle dewatering press is then the technology used in the washing process favorable pre-drying for the finishing departments in closed frontal or other Tumbling possible.

The invention is presented as follows: Fig. 1: Scheme of the known Execution of a continuous or discontinuous ash line 'existing from the washing pipe, continuously operating through-flow dewatering press (squeezes) and continuously working through dryer.

The staschröhre (1) discharges continuously or discontinuously Put the laundry and water into the unloading device (2); excess drainage flows through an overflow (5) into a collecting container (6) and can thus in the 'wt'ia tube (1) can be reused. After the cycle time of the batch-wise working The unloading device (2) is used for unloading with a punch or cycle drainage press briefly mechanically, pneumatically or hydraulically by means of a device (3) the pivot point (4) is raised and the laundry is # together with the flood water into the container (8) of the batch-wise punch or cycle dewatering press washed in. The unloading device (2) then returns to its starting position back to the beginning of the next labor market.

Claims (3)

Patent claims: tE unloading device (2) for continuous or discontinuous working washing machines and dishwashers for washing and rinsing textile fabrics, e.g. Bo laundry, as part of so-called washing lines, consisting of a so-called Wash pipe, a dewatering press for mechanical dewatering of the washed and rinsed laundry and a dryer or shaker to pre-dry the mechanically dehydrated laundry for the finishing departments, characterized in that the unloading device (2) the punch or cycle dewatering press operating in batches during a cycle time picks up laundry transported out of the washing tube (1). 2. Unloading device according to claim 1, characterized in that the excess water flows through an overflow (5) into a collecting container (6) and thereby can be reused in the ash tube (1) 3. Unloader according to claim 1, characterized in that after a cycle time of the batch working punch or cycle dewatering press (7) the unloading device (2) for short-term unloading mechanically, pneumatically or hydraulically through a device (3) is lifted above the pivot point (4) and thereby the laundry and floodwater into the container (8) of the batch-wise punch or cycle dewatering press (7) is washed in. The unloading device (2) then returns to its starting position back to the beginning of the following work cycle, etc.,
