    • PURPOSE:To eliminate change in mechanical setting caused by change in the specification of a light-weight article to be carried by applying AC power of controlled frequency to a blower in order to give airflow driving force corresponding to the size and weight of the specification of the light-weight article to be carried, to the light-weight article. CONSTITUTION:The frequency of AC power to be applied to a blower 60 is controlled by an inverter in order to give the airflow driving force corresponding to the size and weight of the specification of a PET bottle 10 to be carried, from the blower 60 to the PET bottle 10. It is preliminarily examined through actual operation that AC power of what frequency is applicable to the blower 60 in order to give appropriate airflow driving force, to the PET bottle 10 for each specification, for the PET bottle 10 to be properly carried, and the result is memorized. When the specification of the PET bottle 10 to be carried is changed, the inverter can be simply set to the preliminarily examined frequency. The fine adjustment of the airflow driving force is carried out by using a three-step damper 7.
