DETAILED DESCRIPTION OF THE INVENTION

[0034] As described in the preceding sections, the present invention relates to a system for the production of compacted ice from crushed ice. A detailed description of the invention in reference to a preferred embodiment thereof shown in FIGS. 1 to 8 is described below.

[0035] As shown in said figures, the system for compacting ice of the present invention, in said preferred embodiment, generally comprises a plurality of sub-systems which define the main functions thereof: a receiving sub-system (1) (FIG. 2) configured with means for feeding crushed ice the system; one or more moulding rotary platforms (2) (FIG. 3), the function of which is to serve as a compaction mould for the crushed ice, in addition to conveying the crushed ice and the compacted ice throughout the production process; a sub-system (3) for compacting (FIGS. 4, 5 and 6) the crushed ice, comprising, in its preferred embodiment, at least a press module (4) (FIG. 4), which is preferably fixed and rigid, against which the crushed ice will be compacted, and a compression module (5) (FIG. 5) capable of generating compression forces by means of the movement of one or more press rollers (6); an actuation sub-system (7) (FIG. 7) which generates the movement for the compaction sub-system (3); and, optionally, a bed sub-system (8) (FIG. 8) structurally supporting the assembly of the system. Each of the identified sub-systems is described below.

[0036] The receiving sub-system (1) (FIG. 2) comprises, in its preferred embodiment, an upper receiving hopper (9). The function of said upper hopper (9) is to feed crushed ice for the moulding rotary platforms (2) through at least one opening in the lower region of the upper hopper (9). To restock the crushed ice of said upper hopper (9) manual or automatic feeding means can be used in various embodiments of the invention. Likewise, another function of the upper hopper (9) is to act as a limiting surface for the crushed ice that is located on the moulding rotary platforms (2) at the beginning of the production process. Preferably, the upper hopper (9) will not completely cover the upper part of the assembly so as to leave free space for the press module (4), as well as for removing the compacted ice from the system as it is formed as part of the production process.

[0037] FIG. 3 shows, in a preferred embodiment of the invention, a moulding rotary platform (2) the function of which is to serve as a mould for crushed ice, in addition to being used as a conveying surface for the crushed ice and compacted ice throughout the production process. Said moulding rotary platform (2) preferably comprises a plurality of interchangeable templates (10) provided with one or more moulding openings (11). The functions of said templates (10) are, primarily, to be readily replaceable in the event of malfunction or maintenance, and to offer the capacity to accommodate different technical specifications for the moulds of the compacted ice, both in size and in shape, which are determined in a corresponding manner by size and shape of the moulding openings (11), which can adopt a cylindrical design, prismatic design, etc. The mentioned interchangeable templates (10) are integrated in their respective moulding rotary platforms (2), forming the mould of the compacted ice itself. The crushed ice that is located on the moulding rotary platform (2) will thus fall into said moulding openings (11), and as its passes through the press module (4), it will be compacted by the pressure exerted by the press rollers (6) until it is compacted to the desired shape.

[0038] FIGS. 5 and 6 show the elements of the compression module (5) in addition to the moulding rotary platform (2) in a preferred embodiment. In a preferred embodiment of the invention, said compression module (5) comprises: a plurality of wheels (12, 13), distributed preferably as a group of outer wheels (12) and a group of inner wheels (13), guided by the corresponding guiding tracks (14, 15) (FIG. 6) which together generate the linear movements necessary for compressing the crushed ice; an assembly of lower pistons (16) and press rollers (6), and an assembly of lower wheel-carrying arms (17) and upper pushing arms (18), which accompany the linear movement of the outer wheel (12) and inner wheel (13) and exert compression of the crushed ice against the press module (4). Furthermore, said compression module (5) comprises at least one divisional rotary platform (19), the function of which is to isolate against water the lower part of the compaction sub-system (3) that is located between the inner wheel (13) and outer wheel (12) and the moulding rotary platform (2). In a preferred embodiment, there is a series substantially vertical structural arms (20) which integrally attach the elements of said compression module (5) between said divisional rotary platform (19) and the moulding rotary platform (2).

[0039] In said preferred embodiment, the moulding rotary platform (2) is connected by means of one or more connecting rollers (21) located on the outer diameter and/or on the inner diameter of the interchangeable templates (10). Said connecting rollers (21) thereby serve as an attachment element for the elements of the compression module (5).

[0040] Preferably, the connecting rollers (21) are connected to the upper pushing arms (18). More preferably, said arms (18) are located radially with respect to the divisional rotary platforms (19), in the free space between the lower part of the moulding rotary platform (2) and the upper part of the divisional rotary platform (19). Said divisional platform (19) consists of openings for housing and serving as a guide for both the vertical structural arms (20) and for the lower pistons (16). In turn, in addition to serving as a guide and as reinforcement for the vertical structural arms (20), the upper pushing arms (18) are for carrying and exerting pressure on the press rollers (6), as the latter are pushed linearly by the upper pushing arms (18), obtaining as a result compaction against the press module (4) of the crushed ice, located inside the moulding openings (11). Likewise, the upper pushing arms (18) will be raised by the lower pistons (16), each of them being supported at its lower end on the lower wheel-carrying arms (17) which will move linearly, guided by the movement of the outer wheels (12) and inner wheels (13), when sliding over the guiding tracks of the outer wheels (14) and inner wheels (15) having a variable section.

[0041] Additionally, the lower wheel-carrying arms (17) have a dual function. On one hand, in a preferred embodiment each arm carries an outer wheel (12) and another inner wheel (13), guiding the assembly of the compression module (5). On the other hand, they act as a support for the lower pistons (16). Said lower wheel-carrying arms (17) are distributed radially in the space between the divisional rotary platform (19) and the inner guiding track (15) and outer guiding track (14).

[0042] FIG. 6 shows a preferred embodiment in which there can be observed the inner guiding track (15) and outer guiding track (14), having a circular path of travel and with different heights on which both the outer wheels (12) and the inner wheels (13) slide. When travelling across the space projected by the press module (4) on the guiding tracks (14, 15), they generate an upward movement in the outer wheels (12) and inner wheels (13), therefore raising the position of the entire assembly formed by the outer wheels (12) and inner wheels (13), lower wheel-carrying arms (17), lower pistons (16), upper pushing arms (18), and press rollers (6), with the latter exerting pressure and compacting against the press module (4) the crushed ice which will be located inside the moulding openings (11).

[0043] FIG. 7 shows the actuation sub-system (7) of the invention, the main function of which is to generate the main rotational movement of the system, as described above. To that end, the actuation sub-system (7) comprises in a preferred embodiment a ring gear (22) fixed integrally to outer diameter of the moulding rotary platforms (2), engaged with a pinion (23) and a motor (24) capable of rotating the assembly. Optionally, in said preferred embodiment, the invention has one or more secondary motors (25) capable of providing movement to respective impellers (26) located on the moulding rotary platform (2) the purpose of which is to aid in the crushed ice not being compacted before beginning the actual mechanical compaction process of the invention.

[0044] FIG. 8 shows, in a preferred embodiment, the bed sub-system (8) configured for supporting the assembly of the system. Said bed sub-system (8) preferably comprises a platform (27) and a bed base (28) with a plurality of supporting legs (29) for being supported on the ground or any other bearing surface. Additionally, the sub-system (8) may optionally comprise an inspection window (30), which facilitates repairs and changing of parts in the event of a possible malfunction, from the lower part of the system.

[0045] In this manner and as described, the invention provides a system for compacting crushed ice capable of forming compacted ice by means of a continuous process, thereby improving the limitations of the state of the art.
