Glue Sensing Device/Sensor

Maybe a barcode reader could be adapted to this? (Just an idea for detecting stripes.)

Hi,

This should be easy, as your box is brown and your glue is while, simple colour sensor with small PLC to count the strips will solve the problem.

In Malaysia we have Keyence (www.keyence.com). They for sure have solution, but expensive

You also can look for Autonics. they also have sensors, heck all automation supply company should have a light/colour sensor which can detect this. Light sensor can be used too, since the glue is white you get most reflection and the box will not, comparing this can give count.

P.S - we existed automation business in 2005, but I am still rather active in it, unable to solve your problem, only able to help and guide.

A jet of air might be enough to blow the un-glued box off the line while leaving the glued ones on it.

This company does that...

If the bead of glue has height. A sensor to measure the change in surface height.

Speed is the potential problem here. Getting a sensor that will determine if a box has glue is just the first part where speed can make things difficult. Once a box has been identified as having insufficient glue, you will have to find a way to sort the rejected box out of the production line.

I think it is possible by using laser sensors check for http://www.timetechusa.net/Laser%20Sensor.htm this type of sensor may be suitable

Another possibility is capacitive sensors. They have been used for this exact application and do not require any changes in the chemistry of the glue.

Here is a barcode reader .

It is built entirely in Visual C#, and it supports Microsoft .NET 2.0, 3.0, 3.5 and above versions. This control is very easy to install into your .NET, ASP.NET, Visual C# and VB.NET applications.

Hope it helps!
