After leaving the crate washer and before reaching the packer, it is necessary to check if the crate is really empty and ready for packing. Jammed bottles or foreign objects in the crate disturb the packer and causes down time.
The new BBULL LK-U BBULL TECHNOLOGY offers new ultrasound technology for empty crate
inspection after the crate washer. The empty crates are scanned three dimensionally while passing
the sensor bridge by high-frequency ultrasound with a scan rate of 450 Hz. The empty crate
inspection system is designed to detect jammed bottles as well as foreign substances in the crate.
All sources of error are recognized before reaching the packer and this
reduces down time. Consequently faulty crates can be detected and
removed from the production process. Depending on the empty crate
inspection system, the possibilities are simple rejection of the faulty
crate to a buffer or the activation of an acoustic, or an optical alarm.
The outstanding feature of the BBULL LK-U is its simple operation.
It offers optimal comfort and high performance, but with an extremely low
space requirement. The profiles of the current types of crates are stored in
memory with a TEACH IN mode, (It`s possible to store up to 16 different
types of crates). Changing the crate type can be done at the touch of a
button without mechanical modifications.

The empty crate inspection system consists of a sensor bridge and the control unit BBULL PC-400. The sensor bridge is adjustable in height through a spindle. (Used for installation only).
The sensor bridge is equipped with a line of 30 high-frequency (400 kHz) ultrasound sensor.
While being transported under the sensor bridge, the crate is scanned with a scan rate of 450 times/s. The high frequency ultrasound in combination with the extremely high scan rate allows a resolution down to 1 mm.
The evaluation of the sensor signal as well as the control to the rejection or distribution unit is carried out by the control unit.
To guarantee trouble-free-operation, we recommend a transport through the sensor bridge over a rubber belt and a crate separation of 100 - 150 mm.
