Abstract

A linear magazine for storing and automatically dispensing objects (10) disposed in stacks or in lines within juxtaposed bins (1) includes an extractor cartridge (20) associated with each bin and co-operating with a cog belt (50) which is common to all of the bins. The invention is applicable to dispensing cassettes, books, cigarettes, spare parts, etc.

Claims

1. A magazine for storing and automatically dispensing packaged objects, the magazine comprising a plurality of juxtaposed bins constituting a linear structure which is generally rectangular in shape, each bin having a horizontal surface and being intended to store a plurality of objects, each bin having an evacuation opening in a front face suitable for passing out a single packaged object, each bin including an ejector cartridge in said horizontal surface thereof, said cartridge serving to eject one packaged object at a time from the bin, said cartridge comprising firstly a chain of links situated substantially in a horizontal plane, at least one of said links including at least one means suitable for ejecting said object through said evacuation opening when said chain is set in motion, and secondly ejection control means for meshing said chain with a cog belt situated parallel to the front face of said linear structure level with the ejector cartridges and operatively coupled with means for constantly driving said cog belt in translation, and wherein said cog belt solely provides the movement of the chain once engagement of the linked chain with said cog belt is effected by said ejection control means, and a conveyor positioned parallel to said structure for removing said ejected object.

2. A magazine according to claim 1, wherein each bin is suitable for containing a vertical stack of boxes and has two side faces, said bin front face opening for passing out the object is situated at the bottom of the stack, said bin further comprising, a rear face, said horizontal surface is a bottom surface with a slot running between the bin front face and rear face, said bin being provided beneath its bottom surface with said ejector cartridge including a closed guide, said chain links sliding around said closed guide and having two rectilinear portions, one of which is lower than the other, said rectilinear portions being interconnected by two semicircular portions forming a closed loop therewith, each link having a meshing tooth on its outer side face except for two diametrically opposite links, which are provided with respective ejector pegs positioned for passing along said slot and constituting said ejection means, and said ejection control means being provided near said rear face for causing a peg-carrying link to advance by one notch.

3. A magazine according to claim 1, wherein said objects are boxes, each bin is suitable for containing a vertical stack of said boxes and has two side faces, said bin front face opening for passing out the box is situated at the bottom of the stack, said bin further including a rear face, and said horizontal surface being a bottom surface with a slot running between the bin front face and rear face, said bin being provided beneath said bottom surface with said ejector cartridge, said ejector cartridge chain of links being rotatable about a shaft parallel to said cog belt between a chain rest position and a chain working position, said ejection control means comprising an electromagnet for controlling said positions, said chain contained in said cartridge including two links having side meshing teeth truncated so as to avoid engaging said cog belt when said cartridge is in its rest position, but having adjacent links which engage with said constantly driven cog belt when the chain is in its working position.

4. A magazine according to claim 1, wherein said bin horizontal surface is a ceiling, each bin has a rear face intended to contain a row of packages hanging from a rod fixed to the rear face of the bin, with each bin ejector cartridge being contained in said ceiling, said cartridge chain of links having respective side meshing teeth, and a plurality of toothless links, with one toothless link per package, said toothless links carrying respective ejector pegs, and said ejection control means being provided in the vicinity of said bin rear face to advance a peg-carrying link by one notch.

5. A magazine according to claim 1, wherein said conveyor includes drive means for driving said conveyor;

said drive means including means for coupling drive means of a conveyor of an analogous magazine juxtaposed thereto.

6. A magazine according to claim 1, wherein said cog belt is made of a flexible substance which is sufficiently flexible that each of its teeth is elastically crushed by a meshing tooth of one of the links.

7. A magazine according to claim 1, wherein said links engage one another by a ball-and-socket type connection.
