Product Overview For laundries that desire automatic post-sorting ability, AIR CHICAGO QUATTRO is a newly designed high speed towel and gown folder combines the precision processing standards of the original with a specialized four lane exit conveyor configuration, giving it the potential to sort three or four unique items in a single program, depending on finished package size. This unprecedented level of flexibility enables an operator to randomly feed up to four different size towels, gowns and other tumble dried items all at the same time. The automatically determines the size of the item being processed and chooses and performs the desired fold pattern. A newly designed crossfold section uses reversing conveyors to perform folds for accurate, dependable jam-free operations. Folded items are directed to one of four internal conveyor drop areas for stacking with similar items.

Sep 17, 1996 - A folder for laundry pieces such as towels is provided which employs opposed air discharges for forming precise French folds. The sequence and timing of air discharge through opposed air bars is. Download PDF 5556360 PDF help. And guiding action of blocks 39 provided by guide rods 24 will effect. Chicago Air Small Piece Folder. Call for price. Category: Towel Folders. Description; Description. Chicago Air Small Piece Folder Excellent Condition.

For larger folded packages, the system links a pair of adjacent delivery conveyors to accommodate the larger size. This allows the Air Chicago Quattro the versatility to sort in 2 large stacks, 1 large and 2 small stacks, or 3 or 4 small stacks.

Folded stacks are then discharged to the delivery conveyor, which may be set up in the field to deliver stacks back to the front feed operator, or to the rear for further conveyance or handling. Industries • • • • • • • • • •.

BACKGROUND OF THE INVENTION 1. Field of this Invention This invention relates to a high-production folder adapted to form French folds in foldable laundry items by means of air discharge. More particularly, a laundry folder is provided with controlled air discharge and conveyor movement which increase the speed and efficiency of the folding operations carried out. Description of the Related Art The prior art discloses the use of opposed air blasts in forming folds in sheet material, as in Cran U.S. However, this patent does not suggest the air discharge control resulting in optimum speed and efficiency present in the apparatus of this application.

Introduction to robotics oussama khatib pdf to word document. Landgraf et al. 4,060,227 discloses opposed air discharge tubes which form French folds in small laundry pieces. This patent does not suggest, however, the folding control and flexibility of folding operation present in the apparatus of this application. Sherrill U.S. 3,423,083 discloses the use of opposed alternating air discharges for forming folds in a continuous length of fabric with the assistance of hold-down bars.

However, there is no suggestion of the high speed folder of laundry items of the type hereinafter disclosed. Sjostrom U.S. 2,754,113 discloses a sheet folding machine which may employ reciprocating plates or air pipes for forming longitudinal folds in sequence in sheet material. This patent does not suggest the high speed efficiency possible with coordinated air discharges and the conveyor movement of this invention. The folder of this invention employs oppositely disposed air bars which discharge air in sequence for folding opposed panel portions of conveyed articles, and, in particular, towels, into a French fold. The air bars are responsive to an article measuring device and controller which regulate the air discharge sequence and the panel folding sequence. As a result, closely spaced articles such as towels may be folded without danger of an air discharge tending to unfold an adjacent, already folded towel.

The folder also provides hesitation of the folding air discharges as well as conveyor hesitation for minimum time periods in effecting maximum production as will hereinafter be explained in greater detail. It is thus an object of this invention to provide a high speed folder for foldable laundry articles, particularly towels, which employs oppositely disposed, sequentially operable air discharge means whereby conveyed articles are efficiently folded in closely spaced relationship. It is another object of this invention to provide a laundry folder and process for forming French folds in which the particular sequence of air discharge by opposed air bars is responsive to an article measuring means in conjunction with a controller while the articles folded are conveyed by a folder conveyor. It is a further object of this invention to provide a folder for laundry articles which is able to effect French folding of large foldable articles in the stationary position in a minimum amount of time. The minimum folder conveyor stoppage enables the folder to attain desired maximum production.
