BACKGROUND OF THE INVENTION

Different machines that protect stuffing machines are known in the state of the art.

Traditionally there are two types of machines, those that use a piston and those that use other mechanisms because they are smaller machines. The piston is commonly used for machines with large volumes of product to be stuffed. The antecedents refer to this second group.

Thus, Spanish Patent 0538595 (ES8606983) "IMPROVEMENTS INTRODUCED IN THE DOSING MACHINES OF MEAT PRODUCTS" belongs to the state of the art, from 1984, in the name of Mr. Tomás MATARÓ SANS, which refers to modifications in stuffing machines -meat product dosing machines consisting in that: the rotor adopts a slightly eccentric position in relation to the wall of the chamber, and is arranged above the blades, preventing their axial displacement; Said blades have at their lower internal angle a projecting appendix that remains inserted inside a groove or groove defined in a fixed, removable part, which acts as a cover for the bottom of the cavity; The race describes an eccentric path in relation to the wall of the chamber, so that said link causes, when the rotor rotates, a sliding movement of the blades, forward or backward, according to a pre-established program. The Spanish Utility Model is also known, nor ES0289679 “Dough stuffing machine for pork butcher, PERFECTED”, in the name of D ^a Isabel ARNER BITRIAN, from 1985, which refers to a perfected dough stuffing machine for pork meat, of the type Continuous filler from a bladed rotor, which rotates inside a chamber provided with a mass admission port and a port; of expulsion, the chamber being assisted by air intake ducts for compacting the mass, essentially characterized in that the chamber has a sector prior to the intake port and a sector after said port which is concentric to the rotor and determines a section of mass to mass exhaust manifold.

Finally, it is worth highlighting the Spanish Patent or ES0283393 “CONTINUOUS VACUUM PLASTER”, in the name of Mr. Miguel SUBILS BENEYTO, from 1962, which refers to a continuous vacuum stuffer, which essentially consists of a central body, occupied by a Dosing drum, according to claim two, fed by the product housed in the upper container through a loading hopper, in which an Archimedean thread is arranged, according to claim three, to facilitate the descent of the product, and supported by a lower cabinet-bench, inside which the doser drive motor is housed, the vacuum pump in charge of maintaining a depression in said doser, in order to improve the resting conditions and advance of the product and the other accessories, being arranged in its upper lateral external part the controls of the various organs and control instruments, while in its front part, under the discharge nozzle of the produ cto of the dispenser, a lever is arranged so that the operator can, with his knees, connect or disconnect the dispenser. In Figure 1 you can see a vertical rotor inside the machine. BRIEF DESCRIPTION OF THE INVENTION

The present invention is framed within the sector of stuffing machines for meat products, those that do not use a piston to move the meat.

The closest document is Spanish Patent n ° ES0283393 "CONTINUOUS VACUUM STUFFER".

Said patent shows a rotor arranged in such a way that solves the problem of getting the meat to move in a more direct way, acting by gravity.

On the other hand, it has the disadvantage that in the outlet part it can cause either jams or excessive compaction of the meat due to the eccentric that moves it, which prevents on the one hand not having a uniform quantity of product in the cells that are formed by the action of the blades, since the cells are of different sizes, nor is the outlet wide enough to allow the compacted product to come out because the eccentric itself prevents the outlet. This is mainly due to the difficulties in controlling the eccentrics together with the mass of the product and the action of the force of gravity.

These previous problems do not exist in the machines that have flat rotors, because gravity does not influence, but, on the contrary, these machines by forcing the product to change direction, it is mistreated, causing the white meat to come out, which which leads buyers to reject it, thinking it may be fat.

The present invention solves the aforementioned problems by means of a vertical rotor that has blades that, by means of a guiding mechanism, create cells to transport the meat and then said blades. They move by the action of the cylindrical cartridge, guiding the meat towards the exit, hiding as they approach a guide claw and redirected the meat by the guide claw that prevents it from rising upwards.

An object of the present invention is a continuous meat stuffing machine, of the type that comprises a chassis, a hopper with an agitator shaft where the product to be stuffed is arranged, which is attached to a rotor that comprises an inlet connected to the hopper and an outlet, and because it comprises means for driving the rotor and means for driving the agitator shaft, characterized in that the rotor is arranged vertically, outside the chassis and comprises: a cylinder, which defines a first base next to the chassis and a second removable base, comprising the inlet and outlet, wherein the first base comprises a hole for the passage of the rotor drive means into its interior, a guide channel, which forms a closed circuit, for positioning of some vanes with a guide that slide through the guide channel, a cylindrical cartridge that is located inside the cylinder through the opening that remains when the second base is removed, which is connected to the means of a operation of the rotor inside the cylindrical cartridge and comprising grooves, arranged radially, through which the blades move, said cylindrical cartridge defining a loading space between the inner walls of the cylinder and the outer walls of the cylindrical cartridge, a diverter pawl located above the outlet that blocks the loading space by diverting the product to the outlet, and because the rotor drive means rotates the cylindrical cartridge in the direction from the entrance to the diverter pawl previously passing through the outlet, and because the guide channel: is parallel to the interior walls from the entrance, the pallets occupying their maximum extension, separating the cargo space into cells, pushing the product, and is no longer parallel to the interior walls when approaching the exit, changing its direction and approaches the hole, the vanes also initiating a movement towards the interior of the grooves, leaving the blades hidden inside the grooves at the moment when the diverter pawl blocks the loading space next to the outlet and the pallets extend again once the diverter pawl has been passed and as They approach the entrance again, and because the referred blades that slide inside the guide channel by means of their guides, perform a double movement, one of rotation with respect to the cylindrical cartridge and another of translation with respect to the guide channel.

CONCRETE EMBODIMENT OF THE PRESENT INVENTION

Thus in figure 1 a chassis 1, a hopper 2, a rotor 3, an inlet 4, an outlet 5 and a second base 24 are illustrated. Figure 2 shows the hopper 2, an agitator shaft 7, a stirrer shaft drive means 8, a pump 22, the inlet 4, a rotor drive means 6, the outlet 5, a cylindrical cartridge 9 , a cylinder 1 1, an opening 17, a deflector claw 18 and a suction means 21.

Figure 3 shows the inlet 4, the outlet 5, the cylindrical cartridge 9 with its grooves 10, the cylinder 1 1, a first base 13, some vanes 15, the diverter claw 18, the suction means 21 and some cells 2. 3.

In figure 4 the inlet 4, the outlet 5, the rotor drive means 6, the cylinder 1 1 with its hole 12, a guide channel 14, the vanes 15, the diverter pawl 18, a space of load 19, interior walls 20 and cells 23.

Figure 5 shows the inlet 4, the outlet 5, the rotor drive means 6, the agitator shaft drive means 8, the cylinder 1 1, the first base 13, the guide channel 14, the paddles 15 with its guides 16, the deflector claw 18 and the inner walls 20.

Finally, in Figure 6 the cylindrical cartridge 9, the grooves 10 and a housing 25 are illustrated.

Thus, the continuous meat stuffing machine of the present invention consists of a chassis 1 that covers the important elements of the machine, a hopper 2 with an agitator shaft 7 where the product to be stuffed is arranged.

The agitator shaft 7 can incorporate the most necessary accessory (not illustrated) such as an auger or a paddle, or a rotating rod, etc. driven by the drive means of the stirrer shaft 8, in this embodiment a gear motor. The rotor 3 comprises an inlet 4 connected to the hopper 2 and an outlet 5 through which the product to be stuffed exits by means of an accessory that is not claimed.

The interior of the rotor 3 rotates thanks to means of driving the rotor 6, in this case for example a gearmotor.

The rotor 3 is arranged vertically, in this way it facilitates that the meat is not mistreated, does not appear with white marks and is more tasty.

Likewise, the rotor 3 is located on the outside of the chassis 1, in this way it is much easier to access it for maintenance, than in the rotors that have been shown in the state of the art, which are inside and implies that the hopper 2 has to be raised to access its interior and, for example, clean it, something that does not happen in the present case, in which the second base 24 can be removed and access to the interior to clean or perform tasks of maintenance.

The cylinder 1 1 defines the first base 13 together with the chassis 1 and the second removable base 24, which allows the latter access to the interior of the rotor 3, as explained above.

The first base 13 comprises a hole 12 for the passage of the drive means of the rotor 6 to its interior, in this embodiment it is a shaft that is connected to the gear motor 6

The first base 13 also comprises the guide channel 14, which forms a closed circuit, for the positioning of blades 15. The blades 15 have a guide 16 that is located in the lower part and that slides through the guide channel 14. The cylindrical cartridge 9 is located inside the cylinder 1 1 through the opening 17 that is formed when the second base 24 is removed from the cylinder 1 1.

Said cylindrical cartridge 9 is connected to the driving means of the rotor 6 inside the cylindrical cartridge 9 (Fig. 6).

Said cylindrical cartridge 9 also comprises the grooves 10 through which the blades 15 move.

The cylindrical cartridge 9 also defines a loading space 19 between the inner walls 20 of the cylinder 1 1 and the outer walls of the cylindrical cartridge 9, that is, a space where the meat accumulates from the inlet 4.

The diverter claw 18 is located inside the cylinder 1 1, next to the interior walls 20, located above the outlet 5, blocking the loading space 19 and therefore diverting the product that arrives by the push of the pallets 15 to the exit 5.

The rotor drive means 6 rotate in the direction that goes from the inlet 4 to the diverter pawl 18, previously passing through the outlet 5, that is, it goes from the inlet 4 to the outlet 5 and continues to the diverter pawl 18 and from there at entrance 4 again.

The guide channel 14 is parallel to the interior walls 20 from the entrance 4, where the pallets 15 occupy their maximum extension within the cargo space 19, further separating the cargo space 19 into cells 23.

The pallets 15 also push the product towards the outlet 5 and when approaching the outlet 5, the pallets 15 change their direction and approach the hole 12, the pallets 15 then being hidden inside the grooves 10, just at the moment when the deviator nail 18 it blocks the loading space 19, preventing the pallets 15 from colliding with the diverter pawl 18.

This happens because the blades 15 have guides 16 that slide inside the guide channel 14, performing a double movement, one of rotation with respect to the cylindrical cartridge 9 and another of translation with respect to the guide channel 14, that is that is to say, while the blades 15 rotate, they move thanks to their guides 16 with respect to the route marked by the guide channel 14.

Subsequently, once the blades 15 pass the diverter claw 18, they are extended again as they approach the entrance 4 again, due to the route marked by the guide channel 14.

Optionally, the inner walls 20 of the cylinder 1 1 and the outer walls of the cylindrical cartridge 9 are parallel to each other, something that constructively facilitates the assembly of the machine and the stability of the rotational movements.

To facilitate machine cleaning tasks, the blades 15 are removable. Unlike the background of the invention, in the present invention the hopper 2 must not move to access the interior of the rotor 3, nor access the interior of the chassis 2, only by releasing the second base 24 and removing the cylindrical cartridge 9 can remove the blades 15.

Optionally, to remove moisture, suction means 21 connected to a pump 22 are provided that suck inside the rotor 3.

To prevent the meat from being abused, the arc of circumference between inlet 4 and outlet has been thought to be greater than 180 ° and less than 270 °, forming an angle of approximately 90 ° if inlet 4 and outlet 5 were extended inside rotor 3.

In a specific embodiment, the stuffing machine would be put into operation, with the two gear motors 6,8 and the pump 22 operating.

Next, the operator would introduce the meat inside the hopper 2 and the agitator shaft 7 with the most convenient accessory depending on the meat, would begin to rotate and press the meat so that it is directed to the entrance 4 and there inside the rotor 3.

Once the meat enters the interior of the cylinder 1 1, it is delimited by the inner walls 20 of the cylinder, by the cylindrical cartridge 9, by the first base 13, the second base 24 and by the paddles 15.

The gear motor 6 rotates the cylindrical cartridge 9 which drives the blades 15 that are inside the grooves 10. The blades also move according to their guide 16 which is located in the guide channel 14.

As the cylindrical cartridge 9 advances, it displaces the meat and enables a new cell 23 to be filled by inlet 4.

When the blade 15 reaches approximately perpendicular with respect to the outlet 5, the guide channel changes its path, approaching the hole 12 in the center, through which the axis of the gear motor 6 passes, forcing the guide 16 to approach the hole 12 and consequently moving the vane 15 towards the hole 12 initiating the maneuver of hiding the same inside its respective groove 10.

This also avoids that when the paddle 15 passes the level of the diverter pawl 19, the paddle 15 is completely hidden within the groove 10 and does not hit the diverter pawl 18. Once the diverter claw 18 has been passed, the guide channel 14 varies its path until it reaches the path started at the entrance 4, leaving a closed circuit, and the respective pallet 15 is deployed again inside the cylinder 11.

On the other hand, when the paddle 15 reaches the vicinity of the exit 5, which is when it is hiding inside the groove 10, the inertia that carries the meat pushes it towards the exit, guided by the diverting claw 18 that directs it towards exit 5 and prevents it from continuing inside the cargo space 19.

The present invention describes a new continuous meat stuffing machine. The examples mentioned here are not limiting of the present invention, therefore it may have different applications and / or adaptations, all of them within the scope of the following claims.
