Cartridge for a feeding device

Abstract

A cartridge (1) in the form of a cylindrical container with eternal fixing ribs, a releasing unit (3) of the rear cartridge in the rear window (4) of the cartridge and a mechanism pressing the shell against the inner surface of the cartridge through the front window (5) of the cartridge (1). The front window (5) of the cartridge (1), together with the pressure plate unit (6), are placed inside the cartridge (1) within the cylindrical part of the shell loaded into this cartridge (1). At least two transverse rods (8) are affixed to the pressure plate (6), the ends of which are moving within slots (14) of side guides (12) affixed onto the cartridge (1), on both sides of the front window (5), wherein the pair of ends (11) of each transverse rod (8) is moving within the pair of slots (14) of side guides (12). Each of the side guides (12) is located near the side edge of the front window (5) of the cartridge (1) and is placed on linear moving guide (13) provided with a return spring (18). Each of the slots (14) in the side guide (12) has a section running at an angle against the surface of cartridge (1), connected to a section parallel to the surface of that cartridge (1).

1 . Cartridge of a feeding device in the form of a cylindrical container with internal diameter corresponding to the external shell diameter, provided with external fixing ribs, a unit releasing the rear flange of a shell through the rear window of the cartridge and a mechanism pressing the shell against the internal surface of the cartridge through the front window of the cartridge, wherein the pressing mechanism has a pressure plate within the front window of the cartridge, the working surface of which is adapted to the shape of the shell surface, wherein the mechanism locking the rear shell flange and the pressure mechanism acting on the front part of the shell are concerted and controlled by an actuator, while rotation axis of the drive element levers are parallel and pass through planes orthogonal to the symmetry axis of the cartridge, wherein the front window of the cartridge together with the pressure plate unit are placed in the cartridge in the cylindrical part of the shell loaded into this cartridge, wherein at least two transverse rods are installed on the pressure plate, the ends of which are sliding in slots of side guides affixed on the cartridge, on both sides of the front window of this cartridge, wherein the pair of ends of every transverse rod is sliding in the pair of slots of side guides, wherein each side guide is located near the side edge of the front edge of the cartridge and is placed on a movable linear guide equipped with a return spring . 
     
     
         2 . A cartridge according to  claim 1 , wherein each of the slots of the side guide has a section running at an angle against the surface of cartridge, connected to a section parallel to the surface of that cartridge. 
     
     
         3 . A cartridge according to  claim 1 , wherein the ends of transverse rods, placed in slots of side guides, are eccentric to these transverse rods. 
     
     
         4 . A cartridge according to  claim 1 , wherein the pressure plate unit is affixed on the outer surface of the cartridge case using fixing swing arms. 
     
     
         5 . A cartridge according to  claim 1 , wherein the releasing unit of the rear shell flange contains the central, swing lever of the releasing unit with a releasing wheel on one side and with drive arms of the drive of the right and left slipper and lever units. 
     
     
         6 . A cartridge according to  claim 5 , wherein the releasing wheel is fixed on and can rotate around the swing lever of the lock. 
     
     
         7 . A cartridge according to  claim 5 , wherein the rotation axis of the lock lever inside the releasing unit is parallel to the transverse rods within the pressure plate unit, wherein the swing arm of the lock within the releasing unit contains rotating axes controlling the slipper and lever units controlling the movement of side guides of the pressure plate unit. 
     
     
         8 . A cartridge according to  claim 1 , wherein the holes in ribs connecting individual cartridges contain brass bushings. 
     
     
         9 . A cartridge according to  claim 2 , wherein the pressure plate unit is affixed on the outer surface of the cartridge case using fixing swing arms.
