<p>PURPOSE:To obtain the small-scale captioned device having high usability by detecting the weight of the accommodated article by an accommodated article weight detecting means installed on the bottom surface of an accommodation shelf and displaying the number of left articles when the detection value reduces below a prescribed value, in an article shelf in a factory, etc. CONSTITUTION:A pump 1 is operated to send the previously calculated prescribed hydraulic pressure into a bellows 10 through a check valve 12 and a stop valve 14. The pressure is set to the force corresponding to the total weight of the weight of an accommodation container 8 and the weight of the left articles. Then, the stop valve 14 is closed. With such constitution, if the article having the prescribed weight is accommodated into the accommodating container 8, the bellows 10 pushes up the accommodating container 8 and suppresses the shift. When the number of accommodated articles reduces, ad the pressure of the bellows 10 overwhelms the weight, the accommodation container 8 is pushed up, and separated from a shelf surface 4, and a pressure switch 15 is operated, and a limit switch 22 operates to display the weight on a display device 7. With such constitution the quantity to be left can be set freely, and inventory control can be made simple.</p> |
