Resumen
A machine for dispensing publications one by one having (a) housing defining an enclosed interior; (b) having an exit opening for dispensing the publications; (c) a platform for receiving a stack of the publications, the platform being supported within the housing for vertical movement between a plurality of positions; (d) a slider which, in an operating mode of the machine, is horizontally movable between fore and aft positions; the slider being disposed within the housing for contacting a topmost publication of the stack with the platform in one of the plurality of positions and for feeding the contacted publication to the exit opening when the slider is moved horizontally; (e) a coin operated mechanism for placing the machine into the operating mode, and (f) a mechanism disposed within the housing for automatically imparting a motion to the slider that pushes the slider against a rear edge of the topmost publication so as to move the topmost publication from the stack to the exit opening when the machine is placed into the operating mode. The mechanism for automatically imparting the motion to the slider includes a motor, a crank and a connecting rod operatively connected to each other and to the slider such that, in the operating mode, the motor rotates the crank which in turn drives the connecting rod to cause horizontal movement of the slider.
Reivindicaciones
1. A dispensing machine for booklets, brochures or the like, of the type operated by introducing coins, which includes a usual mechanism of introduction, acceptance, rejection and return of coins, characterized in that it is made up of a structure that has a horizontal upper panel (6) and a horizontal lower panel (7); a supporting and raising platform (10) for a stack of booklets, which supporting and raising platform (10) may move in a vertical direction guided between several vertical rails or bars (9) the ends of which are fixed to the upper (6) and lower (7) panels; two counter-weights (14) situated one at each side of the said raising platform (10) and joined by means of flexible cables or the like to each side of the supporting and raising platform, the said cables passing through respective pulleys (17) arranged on the upper panel (6) in such a way that the said supporting and raising platform (10) is made to rise by the said lateral counter-weights (14), which are guided by pairs of vertical rails (8) connected between the upper and lower panels; a slider (20) that slides horizontally forward and backward and is situated directly above the stack of booklets arranged upon the supporting and raising platform (10) and held between two lateral guides (19); and a connecting rod (21) jointed by its front end to the front part of the slider (20) to cause the movement of the same, and by its rear end to an operating crank (22) which, in turn, is made to turn by a gearmotor (43) fixed appropriately to the machine's structure, the lower side of the slider (20) having a step (39) facing forward, by means of which it applies, in its rearmost or retracted position, to the rear edge of a booklet situated immediately below, to move it toward the exit opening when the machine is operated. 2. A machine as claimed in claim 1, characterized in that the supporting and raising platform (10) for booklets has on the underside a handle (26) to lower it manually, when empty, toward the lower part of the machine, overcoming the action of the lateral counter-weights (14), to place upon it a new stack of booklets, the machine's structure having lateral profiles (44) below for holding the said platform in a lower position, by means of the introduction of a transverse bar, above the handle, in the appropriate openings of the said lateral profiles (44). 3. A machine as claimed in claim 1, characterized in that the slider (20) that pushes the booklets has on its upper side a large longitudinal recess (40) which interrupts, on its front side, a transverse drill hole (41) parallel to the same, in which an articulation axis of the connecting rod's head is introduced, the rear end of the connecting rod (21) being jointed to a pivot (42) that projects axially from the proximity of the peripheral edge of the crank (22) in the shape of a disc, the centre of which is joined to the output shaft of the operating gearmotor (43). 4. A machine as claimed in the foregoing claims, characterized in that the counter-weights (14) are made up of blocks that have two vertical perforations (33) which are slightly widened at the ends to receive sliding guide collars (15) on the pairs of vertical rails (8). 5. A machine as claimed in the foregoing claims, characterized in that it comprises several dispensing mechanisms aligned side by side, corresponding to the different types of booklets that may be selected by purchasers who operate the corresponding buttons (30) situated on the upper part of the machine, and which dispensing mechanisms are actuated by a common device for introducing and accepting coins.
