Automatic Load Height Sensor

What is ALHS?

Automatic Load Height Sensor, also known as ALHS has many benefits when installed to your Eagle series stretch wrapper. One is to identify the top of the pallet load that our Eagle series stretch wrappers are equipped with.  And two, it will determine when a load has been placed on the your machine. There are several types of load height sensors. For example we have listed two of our common sensors below.

Diffused Light Sensors

Diffused Light Sensor

A diffused light sensor is commonly called as proximity mode. When light strikes the target from various angels it becomes diffused. After light returns directly to the receiver the target has been detected. Factors such as color, size and finish determine the target. The actual sensing range for each model is based upon a “white card test”. The white card has a 90% reflectivity factor and is considered a “standard target”. Targets with darker colored or a matte finish provides less reflectivity. In other words, increase the sensitivity or position the sensor closer to the target.

Operational modes:

  • Diffused with background suppression
    • Sensors with background suppression have a defined sensing range for any object regardless of color, reflectivity or finish. These sensors are easy to install and adjust. As well as detect dark objects placed on shiny backgrounds.
  • Diffused with foreground suppression
    • Sensors with foreground suppression define a “dead-band” from the sensor’s optical window. Objects that fall inside this minimum sensing distance are ignored.
  • Diffused with background evaluation
    • Sensors with background evaluation only evaluate the light reflected by the background (i.e. the floor). If the sensor is not able to see the background, the output will change state. This is useful in applications with odd shapes where direct light at the target cannot be reflected back to the sensors.

Digital laser load height sensor

A laser load height sensor enables long distance detection. This is useful for difficult applications where there must be a focused, visible beam spot. TOF (Time of Flight) is the method used to measure distance using a laser.

The TOF method of detection measures distance by calculating the time it takes for a pulse-emitted beam to leave the sensor, hit the target, and then return to the sensor. Therefore this provides stability of the detected work piece.

Pallet Load Profile?

What is a pallet load profile?

What you should know

A pallet load profile is a way of categorizing the load composition of a pallet. To begin with, you can load pallet in an infinite number of ways. This will often vary from load to load. Next, when positioning the items on your pallet the vertical and/or horizontal profile will change. Incidentally depending on the horizontal and vertical edge profiles, you may be required to use a different stretch film or machine operation.

In conclusion, knowing the load profile of your pallets to be wrapped makes it easier to determine which stretch wrapping machine and stretch film will work best for the given application.

Pallet load profile 'A'
Pallet Load Profile 'A'

Profile 'A'

Type 'A' loads have uniform horizontal and vertical edge profiles. The load footprint is nearly the same size as the pallet deck. Each item contained within the load to be wrapped fits together to form a uniform shape. There are few edges that can puncture the stretch wrap as it is being applied. Due to the uniform lines and lack of snag points, these are the easiest loads to wrap.

 

Pallet load profile 'B'
Pallet Load Profile 'B'

Profile 'B'

Type 'B' loads do not have the same uniform vertical and horizontal edge profiles as loads rated as profile 'A'. The load pattern results in irregular vertical and/or horizontal profiles and may not be the same size as the pallet deck. It is possible that edges may exist on these types of loads that can cause punctures or failure of stretch wrap film.

Pallet load profile 'C'
Pallet Load Profile 'C'

Profile 'C'

Type "C" loads vary from pallet to pallet. No two 'C' loads will have the same vertical or horizontal edge profiles. Sharp edges will require additional stretch wrap management and a higher quality stretch film is recommended to handle this type of difficult load.
