LAUNDRY FOLDING APPLIANCE AND AUTOMATED METHODS OF OPERATING THE SAME
20220298721 · 2022-09-22 ·

A laundry folding appliance includes one or more folding panels mechanically coupled to a cabinet and at least partially defining a folding surface for receiving articles of clothing. An actuating assembly selectively pivots the folding panels to fold the articles of clothing and a camera assembly is positioned in view of the folding surface. A controller obtains one or more images using the camera assembly, identifies the laundry articles positioned on the folding surface by analyzing the one or more images using a laundry identification model, determines a folding protocol for folding the laundry article, and operates the actuating assembly to fold the laundry article in accordance with the folding protocol.

METHOD FOR TREATING LAUNDRY ITEMS

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.

Robotic laundry devices and methods of use

Devices, systems, and methods for repositioning a deformable laundry article are described. For example, a robotic device includes a conveyor configured to transfer the deformable laundry article outside of a work volume, two or more lifters including grippers individually anchored about the perimeter of the work volume, two or more sensors disposed at fixed locations about the work volume, and a memory storing data indicative of repositioned deformable laundry articles. A controller is in operative communication with the memory, the two or more sensors, and the two or more lifters. The controller is configured to receive a signal from the sensors, identify grip points on the deformable laundry article suspended above the conveyor, instruct a lifter to grip and lift an identified grip point to the suspension height, determine whether the deformable laundry article is repositioned, and instruct the lifters to lower the repositioned deformable laundry article onto the conveyor.

20210262135 · 2021-08-26 ·

An apparatus and method for pre-shrinking a wet fabric prior to drying. The apparatus includes, among other components, a balloon extractor station and a hydro-sizer compression station. The balloon extractor station removes some water from the wet fabric. The hydro-sizer compression station is operatively connected to, and disposed downstream of, the balloon extractor station, and compresses the wet fabric in a lengthwise direction, and in so doing, pre-shrinks the wet fabric prior to drying. The method includes, among other steps, extracting some water from the wet fabric so as to form a hydro-extracted and wet fabric, compressing lengthwise the hydro-extracted and wet fabric so as to form a compacted and wet fabric that is now pre-shrunk prior to drying, and drying the compacted and wet fabric so as to form a compacted and dry fabric.
