ARTICLE STORAGE Russian patent published in 2002 - IPC

FIELD: storage pf articles with subsequent issuing item by item. SUBSTANCE: device has frame with base provided with sockets for articles, spring-loaded fixing strips installed in longitudinal and cross rows over base for axial displacement and selectively opening closures of socket inlet holes accommodating compression springs. Each springs. Each strip has axial displacement drive mounted on frame coaxially with strip, connected with one of strip ends and coupled with corresponding control unit. Each control unit has digital indicator, memory register and drive control circuit including decoder connected with control input of thyristor switch whose power input is coupled with current source. It has common distributing valve mounted of frame whose normally closed input is connected with compressed air source, normally open input is connected with atmosphere, output is connected with each drive made in form of normally closed cutoff valve and single-acting pneumatic cylinder whose spring- loaded rod is fastened on strip and inlet channel is connected to output of distributing valve through cutoff valve. Pneumatic cylinder has signal hole and additional inlet channel made in end face of pneumatic cylinder and connected with outlet of distributing valve. Sealing is secured on piston coaxially with additional inlet channel for closing channel by piston in initial position. Signal hole is located in wall of pneumatic cylinder to form pneumatic coupling with inlet channels at end of piston stroke. Each compression spring inside socket is installed on rod with head made for adjustable axial displacement. Each control unit is furnished with pneumoelectric converter whose pneumatic unit is connected to signal hole. Digital indicator and memory register are connected to current source through normally open contacts of electric unit of pneumoelectric converter. Output of thyristor switch placed in drive control circuit is connected to control element of cutoff valve. Each shutoff is formed by two wings, first one being secured on longitudinal strip, and second one, on cross strip in one plane with base surface for displacement on wings from inlet holes of sockets at axial displacement of strips for selective opening of shutoff. Strips of cross rows are installed in slots made in frame base. EFFECT: improved convenience in operation. 2 cl, 7 dwg
