…during material movement, permanently highly precise – in transmitted light
Do you still measure piece lengths by hand in samples? Incoming and outgoing material edges ensure increased wear and measured value deviations when using tactile measuring equipment. Driving against mechanical stops costs processing time. Optical stops must be readjusted depending on their length. Therefore, often there is only a manual measurement in the running-in process. If length errors occur in the current production, the production is declared as a reject. … The solution is non-contact longitudinal light grids. ELOVIS offers the worldwide unique SLM light grid technology for the remeasurement of piece goods up to 5 m in length. This works with an accuracy range of 1/10 mm/m. The non-contact remeasurement of the piece lengths takes place in the SLM system during the material passage in longitudinal direction. The measurement serves the production optimization as well as the good/bad sorting and documentation of the delivery condition of pieces. SLM systems are used to measure the length of cut profiles, tubes, hoses, plates, sheets, blanks, bolts, bars, beams and hubs made of a wide variety of materials. The use of the ELOVIS systems SLM-2 or μSPEED is suited to measure longer part lengths.
Typical piece goods to be inspected:
- plastic and extrusion (profiles, hoses, pipes …)
- metal (profiles, tubes, bolts, rods, bars, sleeves, …)
- Plastic sheets and foil formats
- Metal (sheets, blanks,…)
- Construction and insulation materials (plasterboard and fiberboard, …)
- wood (firewood, KVH, beams, …)
- Chipboards (MDF boards, HDF boards, OSB boards)
- Furniture panels (MFB melamine coated panels, printed panels, lacquered furniture panels, …)
- Paper and cardboard hubs
Typical piece goods production machines with measurement problems:
- guillotine
- Sheeter
- Cross divider
- cutting machine
- saw line, flying saw
- Throughfeed
- punch
- Parting line
- trimming line
