LandSco® Surface Inspection Lights
Improve quality control by detecting and preventing scrap from surface defects with LandSco® surface inspection lights and lighted inspection tables.
Doyle Systems has developed products specifically for this purpose. Among products available to the paper manufacturing market are several models of the Doyle “LandSco Light. ”Several generations of this light have been used on six continents to aid in online and offline inspection and detection of defects during the manufacturing process. Doyle’s new High Intensity series takes it to a higher level.
// How it works:
- The LandSco Light produces a beam of light that is very wide from side to side and very narrow from top to bottom. This focused light beam shines parallel to the surface. The surface is highlighted brilliantly on the side facing the light, and casts a deep shadow on the opposite side.
- Dips, picks, scratches, pockmarks, etc., cast deep shadows within their depths with the side opposite the light catching the light and being highlighted. The lighting also shows surface debris such as dirt, dust, felt hairs, and paper fiber as well.
This combination of highlight and shadow gives the impression of magnification, allowing the viewer to see quickly and all potential defects. Decisions can then be made to correct the causes while they are still too small or too few to produce scrap. This proactive quality control tool can save paper mills tens of thousands of dollars per year in rejected paper.
// Models
Model G / GA
- Used for on-machine inspection or mounted on an inspection table for off-machine inspection.
- Size of the surface to be inspected can be from 42″-48″ wide by 200″ deep.
- Controls for dimming and on/off operation are located on the back of the cabinet.
- Model GA includes a remote control with a 12′ cable for dimming and on/off operation
Model Mini
- Compact, portable version of the Model G.
- Can be placed on the same surface as the sample to be inspected or even on the sample itself.
- Useful for examining roll ends, skid load edges and sheet pulls where it is easier to take the light to the sample rather than take the sample to the light.
Model MS
The Model MS is basically a Model GA acting as the main control unit for any number of additional units attached electronically so that all units operate simultaneously. The additional units operate just like the main control unit except that they cannot operate independently. The unit was designed for continuous on-line inspection for very wide running webs or for off-line inspection of exceedingly large samples such as 4′ x 16′ panels. It offers all the advantages of the Model GA plus the advantage of being able to illuminate much larger surfaces.
