Abstract
Used laundry items are delivered unsorted to laundries. It has previously been usual to initially sort the laundry items after delivery and treat the sorted laundry items, at least by washing, drying, mangling and folding. The preliminary sorting is labor-intensive and time-consuming. The invention proposes to treat unsorted at least those laundry items which must be mangled. Only before folding are the still unsorted laundry items identified and folded in targeted fashion accordingly. After folding, the identified laundry items are sorted according to their identified criteria, in that folded laundry items with the same criteria are stacked on a respective stack of similarly treated and folded laundry items. This reduces the complexity of sorting laundry items.
Claims16
A method for treating laundry items (10), wherein the laundry items (10) are at least washed, dried, mangled, folded and stacked, comprising at least washing, drying, mangling, and folding the laundry items (10) unsorted,
- wherein before mangling and/or folding, a contactless identification is made of the individual laundry items (10),
- wherein the laundry items (10) are identified by contactless determination of at least the type, size, color, pattern and/or weave style of each individual laundry item (10) by means of at least one imaging device (28, 31),
- wherein, before folding, the laundry items (10) are identified at least with respect to folding and stacking criteria, each laundry item is folded according to individual folding criteria, and then the laundry items (10) with the same stacking criteria are sorted and stacked on at least one stack for the laundry items (10) with the same stacking criteria, and
- wherein all of the laundry items (10) are mangled at unchanged mangling temperature, wherein the mangling temperature is selected such that it does not exceed a mangling temperature of the laundry items (10) having the lowest permitted mangling temperature and a flattening path is selected such that the laundry items (10) having the lowest permitted mangling temperature are finally dried during mangling.
