Our quality inspection components help improve and stabilize the quality of products through advanced electronic measuring systems. WH Leary has a wide variety of detection solutions that use different types of detection sensors and bar code scanners.
Glue Detection Sensors
W. H. Leary offers over 70 detection solutions. Below are only a few of the most selected options. For an inspection station not listed here, send us samples to help you decide which solution best fits your needs.
(ITac sensor head and remote amplifier)
Non-UV Glue Detection
Leary’s own iTac™ sensor is the most advanced Glue Detector on the market today. Its design, using optical triangulation, detects glue absence, presence and volume at line speeds in excess of 2000 FPM. It is compatible with our LS-4 or LS-9.16 controllers.
Used in conjunction with our line of controllers, this scanner meets and exceeds the demands of your customers. A bright light spot, small profile and remote amplifier make the iTac™ detector extremely versatile.
The UV30 scanner operates in conjunction with our full line of controllers. This luminescence sensor has a digital reference display for simplicity in programming and set-up. A user friendly two-button programmable keypad sets the threshold, light intensity and hysteresis (lag in response due to carton flutter) allowing for scanning conditions which have very little contrast.
The UV30's patented technology makes it the preferred sensor for UV detection of glue, labels, varnish and much more.
The M06 scanner was developed specifically for monitoring glue defects that occur when using a glue pot. Its moving shuttle design allows you to learn the background before the glue line is learned and challenge the sensor to ensure it is functioning properly. This is a distinct advantage when running at high speeds.
The M06 Microwave Sensor works in conjunction with our complete line of controllers. This side seam detection solution is immune to color variation in the board. With the M06, you will accurately detect skip glue, low glue volume and dry glue. You can use any pot glue with this sensor.
Leary’s infrared hot melt detection scanner will work in conjunction with our controllers. After the glue has been applied, this sensor detects absence, presence and placement of the glue (+/- 1mm at 300m/min) by seeing its heat signature. The controller then receives a signal noting the placement of the glue and can either pass the product or reject it.
The LS-4 and LS-9 controller can be configured to activate your existing hot melt valves. This will allow all settings to be set through one controller, saving set up and maintenance time.
MIXED COPY DETECTION
Barcode Detection
By adding a code reader to your inspection system, you will be able to scan for mixes at 2,000 scans per second. This can be accomplished with a single line code reader or a raster scanner with 5 lines scanning each code. By providing multiple looks at each printed code, you increase the ability to scan at high speeds.
The code reader works in conjunction with our range of controllers to provide accurate reading of all standard ANSI bar codes. The bar code reader accurately verifies Good Read, No Read, Match, and No Match conditions. Each bar code scan is visually verified by an infrared color display and provides real time status for each specific read. This is very useful as a set-up tool for verifying optimal scanner alignment. All codes, whether scanned in the single or raster mode, are read several times guaranteeing reliability and accurate detection.
Leary’s Pharmacode reader will protect against mixing copy, check the absence and presence of color, measure print-to-cut registration and check the cut length or cross length of each carton. The expanded Pharmacode reader will scan at 2000 FPM with cross and cut length accuracy at +/- .1mm (.004").
The color bar sequence and print-to-cut values may be learned by pushing a button or they may be manually entered. When integrated with our LS-4 or LS-9.16 controllers, you can see a real-time display of scanned codes.
Occasionally you will have a carton that is sitting on top of another to form a true doubled carton that may jam your machine. Our double carton detector is simple and easy to use. By learning the width or caliper of a single carton, any increase in size is detected and the machine is programmed to reject the carton or to shut down the gluer.
OTHER DETECTION OPTIONS
Jam Detection
The Leary LS-4 and LS-9.16 controllers are capable of operating 8 and 12 station triggers respectively and one rejection trigger. Each of the 12 station triggers can independently be chosen by the operator to act as a jam station by selecting “overlap” as the “trigger option” for that station. If an overlap is detected at one of these stations, the system sends a shutdown signal. The reject trigger is always a jam station.
Skew Detection
This three sensor configuration ensures that cartons are delivered through the machine from the feed section of the gluer in a parallel position to the flow of the cartons. This detection station is especially useful for scanning on older folder gluers that have a tendency to feed cartons improperly.
Glue Pot Level Control
The model 1000 controller accurately maintains the adhesive level of any glue pot. The system monitors whether the glue pot is low or high. It also monitors if you have a filling or non-filling condition. Simply mount the photo eyes above the glue pot, and the controller does the rest. The controller also features an LED indication of the glue pot's condition. Low and high level states are audibly and visually indicated through the alarm outputs of the controller.
Maintenance of the sensing element is minimal since the photo eyes never make contact with the glue. The controller was designed to automatically maintain constant glue pot levels, while your gluer continues to run without filling interruptions.
