Laundry Conveyors
Commercial laundries typically process over 500,000 items of loose linen per week and, to do this efficiently, automation is essential. Conveyors form the backbone of automated transport systems within laundries, moving separate items of linen between dirty linen receiving areas, through the laundry cleaning processes and on to packing and final dispatch back to the user.
Typical conveyor applications within laundries include:
- Dirty linen sorting
- Indexing step conveyors to load CBW washers with 50–100 kg loads
- Cake conveyors
- Linen sorting belts and platforms
- Dryer loading shuttle cars and takeaway conveyors
- Shrink wrapper infeed and outfeed belts
Many laundries operate on mature sites with legacy equipment already in place, and a challenge for automation is finding sufficient space to install conveyors. All Amber conveyors are designed and built for the individual application and can therefore be tailored to suit site requirements by altering the length, width and height of the belt.
- Powder-coated mild steel beds with stainless steel or powder-coated valances
- Smooth internal surfaces
- Gap-free internal surfaces
- Hemmed edges around valances
- Continuous belts
- Robust finger nip guards located on the crown of the roller
- Horizontal conveyors preferred immediately before drop transfer positions
- Increased conveyor speed when transferring from one belt to another
- No loading above the sides of valances
- Drop heights between conveyors to be no less than the height of the feed conveyor valance
Frequently Asked Questions About Laundry Conveyors
Laundry conveyors automate the movement of linen through commercial laundry operations. They can transport linen from dirty linen receiving and sorting areas, through washing, drying, ironing and folding processes, and finally to packing and dispatch.
Typical applications include dirty linen sorting, indexing step conveyors for loading Continuous Batch Washers (CBW), cake conveyors, linen sorting belts and platforms, dryer loading shuttle cars and takeaway conveyors, and shrink wrapper infeed and outfeed belts.
Yes. Many commercial laundries operate on established sites where space is restricted by existing equipment. Amber designs and builds its laundry conveyors for the individual application, allowing dimensions such as belt length, width and height to be tailored to the site.
Belt conveyors can move dirty linen from delivery vehicles to sorting or washing areas. After washing, pressed linen or “cakes” can be conveyed to sorting areas or directly to dryers, while further conveyors can transfer dried linen towards ironing and folding operations.
Amber identifies snagging as a major consideration when conveying loose linen. Internal conveyor surfaces should therefore be smooth, continuous and wherever possible gap-free, with particular attention paid to avoiding narrowing gaps where linen could become trapped or wedged.
Where one conveyor transfers linen onto another, Amber recommends that the takeaway conveyor operates faster than the feed conveyor. This speed differential helps reduce the possibility of linen becoming trapped at the transfer point and is particularly important when transferring from a declined conveyor to a horizontal conveyor.
Small-diameter rollers, such as the 60 mm diameter rollers referenced by Amber, can be used at the head and tail of conveyors to reduce the V-shaped gap between adjoining rollers. This reduces the distance linen must travel when transferring between conveyors and helps reduce trapping.
Tuck-under occurs when linen sticks to the conveyor belt and begins following the return belt underneath the conveyor. Amber advises reducing belt friction where possible so that linen releases more easily. Where this is not possible, a sensor beneath the head roller can be linked to the conveyor emergency-stop system to detect the problem and stop the conveyor.
Depending on the conveyor arrangement and height, protection can include nip guards, full-panel underguards and local roller covers. Amber notes that guarding should provide appropriate protection while taking account of linen snagging, cleaning access, maintenance and the likelihood of operators coming into contact with moving parts.
Yes. Amber provides conveyor systems for moving linen through multiple stages of commercial laundry operations, and complementary materials-handling equipment such as lifts, hoists and shuttle cars can also be incorporated to improve the efficiency of linen movement around the laundry.
