<p>PURPOSE:To effectively employ a settlement space for the captioned system by detecting the complement of working of an article handling machine moved by instructing its stop position, and thereby starting conveyance in the captioned system with use of intermittent compressed air supply. CONSTITUTION:Sensors 27, 28 are provided on an warehousing port 12 and a delivery port 15 of a bay 24a, which sensors are each adapted to output a low level signal at ordinary time while output a high level when a fork lift, etc., approach thereto. Initiation and completion of warehousing and delivery work are judged based on the change in outputs from those sensors 27, 28. Namely, a solenoid valve serving to control compressed air is opened and closed via a control circuit based on the changes to the H or L level after the approach and separation of the fork lift, whereby the compressed air is supplied and discharged. With such arrangement, delivery work can be facilitated to effectively employ a settlement space for the captioned system.</p> |
