IMPROVED APPARATUS FOR AUTOMATICALLY DISPENSING CONES AND THE LIKE, DESTINED TO CONTAIN ICE CREAM

Abstract: An apparatus for automatically dispensing cones (19) and the like, contained in piled-up condition and in upside-down position inside a plurality of container tubes, comprises a carrousel (13) revolving stepwise over a plane (12) above which the cones (19) rest and slide, and a pair of stationary circular guides (17) positioned between the carrousel (13) and the resting/sliding plane (12), between which guides (17) the first cone (19) of each cone stack is fed and made advance. The pair of guides (17) are provided, at their cone (19) inlet end, with respective inclined planes (18) acting on the peripheral edges of the second cone (19a) of each cone stack in such a way as to separate the first cone (19) from the overhanging cone stack, which cone stack comes hence to be supported by the same guides (17), whilst the first cone (19) rests on the undelying plane (12) while sliding along said plane, until it falls by gravity into a dispensing station (23).

Description: The present invention relates to an improved apparatus capable of automatically dispensing cones and the like, destined to contain ice cream and/or whipped cream, which cones are drawn, e.g., from a coin- or token-operated dispenser with which the cone dispenser in question is associated. As those skilled in the art are very well aware of, the technical problems to be solved in the design of the automatic cone dispensers, are connected with the often irregular shape which the same cones show after being baked, owing to breakages caused by their subsequent handling, and to the fact that they tend to get jammed inside each other, when they are piled up, so that removing them from the cone stack without causing undesired breakages may become difficult. For that purpose, automatic dispensers have been proposed in the past, which however display a very complex, hence expensive, structure, and which are badly integrated, also from an aesthetical viewpoint, with the ice cream machine; in addition to the above, they, precisely owing to their complexity, are difficult to clean, whilst a cleaning thereof should be carried out often, due to self-explanatory hygienic reasons. The general purpose of the present invention is of overcoming the above set forth problems, by providing an automatic dispenser which is very simple from a structural viewpoint, is relatively not very expensive to be manufactured, is reliable in operation, is extremely simply and rapidly cleaned and serviced, and which is finally suitable for being easily integrated, also from an aesthetical viewpoint, with the ice cream machine with which the same dispenser is associated. The above purpose is achieved, according to the present invention, by an improved apparatus for automatically dispensing cones and the like, of the type comprising: a plurality of tubes, with each one of said tubes containing a plurality of said cones, in upside-down position and stuck inside each other, motor means for sequentially moving said tubes in correspondence of a dispenser station which dispenses one cone at a time, and gripping means capable of separating the first cone only, i.e., the cone to be dispensed, from the overhanging cone stack, characterized in that said motor means comprise a carrousel revolving stepwise over a plane on which said cone stacks rest and slide, and that said gripping means comprise a pair of stationary circular guides positioned between said carrousel and said plane, between which guides the first cone of each one of said cone stacks is fed and made advance, with said pair of guides being provided, at their cone inlet end i.e., their end at which the entry of the cone takes place, with respective inclined planes acting on the peripheral edge of the second cone of each cone stack in such a way as to separate said first cone from said overhanging cone stack, which cone stack comes hence to be supported by the same guides, whilst the first cone rests on the underlying plane which supports it until it falls by gravity into said dispensing station which is positioned under said plane. The structural and functional characteristics of the invention, as well as its advantages over the prior art will be better understood from the following disclosure, referred to the hereto attached schematic drawings, which show an exemplifying form of apparatus embodying the principles of the present invention. In the drawings: Figure 1 shows a vertical, sectional view illustrating the apparatus according to the present invention, taken according to the section plane represented by the path I-I of Figure 2; Figure 2 shows a sectional view taken according to the section plane represented by the path II-II of Figure 1; and Figure 3 shows a sectional view of a detail showing the region of cone falling and drawing. Referring to the drawings, the apparatus according to the preferred embodiment of the present invention is generally indicated by the reference numeral 10 and is structurally formed by a box-like base 11 with a top plane 12 on which a carrousel 13 is installed with possibility of stepwise rotation and at a suitable distance from said top plane; along its circumference, said carrousel 13 is provided with cylindrical housings 14 used in order to keep the cones 19 duly trued. The stepwise rotation of the carrousel 13 is driven by a ratiomotor 15 which is housed inside the base 11, and is equipped with an output shaft 16 on which the same carrousel 13 is keyed. Between the plane 12 and the carrousel 13 a pair of mutually parallel, circular guides 17 are installed, which are provided with inclined planes 18 at their inlet end, i.e., their end at which the entry takes place of the first cone 19 of the cone stacks 20, and with horizontal, flat surfaces 21 by which said cone stacks 20 are supported, and on which said cone stacks slide. The stacks 20 of the cones 19 stuck inside each other are housed inside container tubes 22 of traditional type, which are slid on the cone-trueing cylindrical housings 14, with said container tubes coming to rest on said carrousel 13. Inside the base 11 (see Figure 3), a cone 19 dispensing station is organized, which comprises a housing 23 into which the cones 19 fall by gravity through an opening 24 provided through the top plane 12. The cones, brought to a horizontal position by means of positioning pins 25, are drawn by the user through a front door 26 hinged in 27. A removable, external shell 28, e.g., made from polycarbonate, provided with an opening (not shown in the figures) by means of which the tubes 22 are charged to the apparatus, seals the same apparatus by resting onto the base 11, which can be constituted by the same coin- or token-operated unit used in order to control the dispenser. Of course, also an outer shell consisting of one single piece can be provided. The operating way of the cone dispenser provided by the present invention is evident from the above disclosure made by referring to the hereto attached drawings and, briefly, is as follows. The tubes 22 filled with cones 19 are charged to the machine by moving each trueing housing 14 in correspondence of the inlet opening provided through the shell 28, by causing the carrousel 13 to advance stepwise (in the herein depicted example, by 1/8-th of a revolution at a time) by means of a suitable control acting on the ratiomotor 15. When the eight container tubes 22 are all charged, the dispenser is ready to operate in automatic mode. From now on, at each single-step rotation of the carrousel 13, the falling will take place of one cone 19 into the dispensing station 23, by gravity through the opening 24. In fact, as one can clearly see from the drawings, the first cone 19 of each cone stack 20 is delicately separated, and under gradual extraction conditions, from the overhanging cone stack 20 due to the action of the inclined planes 18 of the guides 17, which enter the region between the first cone 19 and the peripheral edge of the second cone 19a. As a consequence, when the carrousel 13 is caused to rotate, the first cone 19 will slide along the resting/sliding plane 12, whilst the second cone 19a and the whole cone stack above it will slide along the surfaces 21 of the guides 17. In such a way, when it will find the opening 24, the cone 19 will freely fall down into the interior of the underlying dispensing station 23. Of course, the operation of the apparatus according to the preferred embodiment of the present invention shall be governed by a purposely provided electrical system (as, e.g., energized by means of a pushbutton control means or a coin- or token-operated unit, which can also govern the operation of the ice cream machine), not depicted in the figures, in that it is within the reach of anyone skilled in the art. It is enough to say herein that by means of said electrical system first sensor means suitable for controlling the stepwise rotation of the carrousel 13, and second sensor means suitable for detecting the presence of the cones 19 can cooperate. Said first sensor means can be constituted by a magnetic sensor 29 installed on the plane 12, which magnetic sensor 29 cooperates with permanent magnets 30 provided on the carrousel 13, and said second sensor means can be constituted by a photo-cell 31. By means of the foregoing, the purpose is achieved which is specified in the preamble to the disclosure, aiming at providing a cone dispenser of very simple and cheap general structure, which is easy to be cleaned and serviced, and which is also aesthetically valid, when is coupled with an ice cream machine.
