Description

DESCRIPTION

Grinder

TECHNICAL SECTOR

The present invention relates to a grinder for grinding spices of the type that includes a static part on which an actuator linked to a trim rotates.

The object of the invention is to provide a mounting system for the grinder actuator-trim assembly that considerably facilitates the assembly maneuvers, by having a geometry that allows automatic positioning by gravity when one part is placed on top of the other in the assembly maneuvers. . Thus, the configuration of the present invention avoids having to face an exact assembly position in said assembly maneuvers, thus simplifying the assembly process, with the consequent saving of time and costs that this entails. Additionally, the device allows the spices to be stirred and pushed, understanding spices as aromatic vegetable substances or herbs, preferably long-leaved ones that move from the interior of the jar or container of the grinder to the outside, without being dosed in a clumped form, as occurs in grinders. conventional.

BACKGROUND OF THE INVENTION

Spice grinders for larger capacity containers (which normally have a container storage capacity equal to or greater than 200 ml) are known as “XXL grinders”. A static, essentially annular piece participates in them, with an internal perimeter toothing, concentric to which an actuator element rotates in which a group of teeth or two groups of coarse and fine grinding teeth are established, respectively, a piece that is linked to a trim by means of four radial wings intended to fit into cross-shaped recesses established on an internal perimeter flange of the trim.

Thus, to assemble these two pieces, it is necessary to face both elements in an exact relative position, which complicates the assembly maneuvers, since the The actuator must be inserted inside the trim manually or by means of a robot arm, and its external body makes accessibility and visibility difficult due to the need for a possible angular readjustment between pieces so that they fit perfectly together.

Additionally, the problem with this type of device is that when the spices materialize into herbs, they tend to clump together inside the container, which has a very negative effect on the dispensing and grinding process.

EXPLANATION OF THE INVENTION

The grinder that is recommended solves in a fully satisfactory way the previously exposed problem, based on a simple but effective solution, which allows to offer some means that allow the automatic positioning in its fall by gravity of the actuator on the trim, in a way that facilitates the assembly of the parts and greatly reduce the operating times of said assembly. Additionally, the configuration of the grinder of the present invention avoids caking of the spices when they are long-leaved, contributing to their efficient grinding.

To do this, we start from the previously described conventional structuring, in which a static annular part with an internal perimeter toothing participates in the grinder in which an actuator provided with complementary teeth plays concentrically and angularly movable within it, counting the element actuator with short radial wings emerging from its base finished in coupling means to the arms of an internal crosshead provided within the trim.

Optionally, the coupling means of the radial wings of the actuator take the form of emerging lugs that can be coupled in complementary holes provided in the arms of the internal crosshead of the trim, so that the aforementioned lugs of the radial wings of the actuator are insertable by gravity in the holes of the arms of the internal crosshead of the trim.

Thus, in the central area of the internal crosshead of the trim, some radial ribs are defined, oriented in the same direction as the arms of the crosshead and in which they define two opposing and inclined longitudinal facets that are complementary to respective projections established on the base of the actuator.

Thus, the actuator has a truncated-conical central recess so that in correspondence with at least three of its equiangularly distributed generatrices, the aforementioned complementary projections are established, in which an end edge is defined with two facets inclined in opposite directions. In this way, regardless of the relative angular position between the trim and the actuator when the latter is inserted and allowed to fall by gravity inside the trim, the edges of the actuator bosses will come into contact with the facets of the crosshead bosses of the trim, sliding along said inclined surface. This configuration causes an automatic rotation and reorientation of one part with respect to another until the arms of the actuator are perfectly opposite the arms of the crosshead of the trim, so that both parts are coupled by simple gravity without the need to carry make any kind of angular adjustment between them.

This, as is obvious, significantly simplifies the assembly operations, reducing operating times.

As detailed above, the stationary part includes a series of internal teeth. These internal teeth collaborate with the complementary teeth of the actuator constituting the grinding means of the device, and define a grinding zone. Well, it has been envisaged that the static piece has a plurality of radial arms internally and in correspondence with the area immediately prior to the grinding area that rest on a concentric ring, so that the radial arms allow the spices to be conveyed with a flow rate considerable towards the area where the cutting or grinding of the spices takes place, avoiding caking. It should be noted that we must understand spices to those vegetable substances or aromatic herbs, preferably long-leaved.

Thus, when reversing the position of the container of the grinder for the dosage of spices by grinding, the matted herbs hit in the first instance against those radial arms, which remove the spices prior to their grinding, causing them to they separate or loosen, facilitating their flow to the grinding mechanism or media.

Optionally, it has been provided that, in the confluence area of the radial arms with the internal wall of the fixed or static part, wedge-shaped partitions are established that reduce the space or clearance defined between the complementary teeth of the actuator and the teeth interiors of the static piece, that is, between the elements or grinding media, which favors the cutting of herbs to a smaller size.

These partitions would act directly in conjunction with the complementary teeth of the actuator in the herb chopping, as an additional and complementary element of the internal teeth arranged on the internal face of the static piece, which protrude a smaller width but participate in a greater number

Finally, it only remains to point out that the use of two parts in this mobile assembly (actuator/trim) allows the use of different materials for one and the other part (of greater hardness for the actuator, and less cost for the trim), with the consequent cost savings that this entails.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the grinder for grinding spices of the invention is constituted, as is conventional, from three parts, a static part (1), an actuator (2) and a trim ( 3).

The static part (1) has an annular configuration, with internal teeth (4), a part on which the actuator (2) is concentrically movable. Thus, the actuator (2) is provided with complementary teeth (6) that are responsible for grinding the spice by operating with the internal teeth (4) of the static part (1). Thus, the complementary teeth (6) of the actuator (2) with the collaboration of the internal teeth (4) of the static part (1) constitute the grinding means, defining a grinding zone. Optionally, the actuator (2) is provided with blades (5) that emerge from its base and are responsible for forcing or dragging the spice so that it is ground between all the internal teeth (4) of the static part (1) and the complementary teeth (6) of the actuator (2).

In any case, according to the preferred embodiment illustrated in the figures outlined, the actuator (2), as is also conventional, includes four radial wings (7) emerging from its base, ending in emerging lugs (8) that are intended to be coupled in holes (9) provided in the arms of an internal crosspiece (10) of the trim (3), crosspiece (10) that defines windows (11) for the passage of spices once ground by means of the set of teeth, namely: the inner teeth (4) and the complementary teeth (6).

Well, in accordance with the essence of the invention, it has been planned that radial ribs (12) are established in the central area of the crosshead (10), oriented in the same direction as the arms of the crosshead (10). and in which two opposing and inclined longitudinal facets (13) are defined that are complementary to respective projections (14) established on the actuator (2).

The actuator (2), as shown in figure 2, has a truncated-conical recess (16) on which four projections (14) are preferably established, and more specifically arranged in correspondence with four of its generatrices, being equiangularly distributed. in diametrically opposite arrangements two by two.

In these projections (14) inclined facets (13') are also defined in opposite directions, said projections (14) defining an internal hollow in correspondence with the base of the truncated-conical recess (16). Thus, the internal hollow defined by the projections (14) is formally suitable to receive within it the radial ribs (12) provided in the crosshead (10) of the trim (3), without angular clearances. In this way, the facets (13) of the radial ribs (12) of the crosshead (10) determine automatic and self-oriented positioning means for the insertion of the actuator (2) inside the trim (3).

Thus, and as previously mentioned, when the actuator element (2) is inserted inside the trim (3), although the crosshead (10) is not perfectly aligned with the radial wings (7) of the actuator (2), this will not be a problem, as shown in figure 4, since in this position of angular offset, the edges that define the pairs of inclined facets (13) or (13'), will come into contact with the facet of the complementary piece , so that when dealing with inclined surfaces and smooth, will force the relative displacement of one piece and the other according to the direction of angular reorientation of these facets, causing the relative angular position between one piece and another to self-adjust until the lugs (8) of the radial wings ( 7) of the actuator (2) with the holes (9) of the arms of the crosshead (10) of the trim (3), so that the actuator (2) and trim (3) are perfectly joined in their exact relative position, all This through a simple and fast maneuver.

Additionally, the static piece (1) includes internally and in correspondence with the zone immediately before the grinding zone a plurality of radial arms (18) that rest on a concentric ring (17), the grinding zone being defined by the zone in which the internal teeth (4) of the static part (1) coincide with the complementary teeth (6) of the actuator (2). The radial arms (18) determine in the overturning of the container some prominent elements on which the spices hit, preferably long-leaved herbs, if they are caked, before reaching the grinding area, thus producing their loosening. or separation, and causing a more fluid and adequate flow of said herbs towards the grinding zone.

As can be seen in the figures outlined, in a preferred embodiment of the invention it has been provided that, in the confluence area of two or more of the radial arms (18) with the internal wall of the static part (1), establish some wedge-shaped partitions (19) that reduce the space or clearance defined between the complementary teeth (6) and the inner teeth (4), which favors the cutting of long-leaved grasses to a smaller size, determining a additional cutting or grinding element for this static piece (1) together with the inner teeth (4).

As previously mentioned, since the mobile element of the grinder is made up of two parts, such as the actuator (2) and the trim (3), this allows the use of different materials for one part and the other, so that the actuator (2) is made of a very hard material, while less hard and consequently cheaper materials can be used for the trim (3) without negatively affecting the functionality of the grinder.
