DESCRIPTION

Packaging closing machine.

Object of the invention

The present invention relates to a container closing machine, generally of glass, by implanting the corresponding lid.

The object of the invention is to provide a machine that, in addition to allowing to automate the process of closing the containers, has a simpler, more versatile and efficient structure.

The invention is in the field of food product packaging.

Background of the invention

In the field of practical application of the invention, container sealing machines are known which, although they allow to automate the process of implanting the corresponding caps in the containers filled with the food product in question, present a wide and varied problem, among which The following aspects should be highlighted:

• These are extremely complex machines, in which multiple engines participate, which means extremely high acquisition and maintenance costs

• Lack of versatility when adapting to boats of different sizes both horizontally and vertically

Description of the invention

The packaging closing machine that is recommended solves in a completely satisfactory way the problems previously exposed, based on a simple but effective solution.

For this, the machine of the invention is constituted from a Lower frame in which a longitudinal conveyor belt is established, through which the containers to be closed are accessed, so that along said conveyor belt different ones are established mechanisms so that the closure of the containers is carried out jointly with the application of steam in order to optimize the preservation of the food contained in the container, when a vacuum in the same is caused when it is cooled so that in said displacement of the package three operative phases are established assisted by the corresponding mechanisms, a first phase in which the lid is deposited on the mouth of the container obliquely thereto, a second phase of "pre-closure", in which the lid is Screw slightly under the action of a side pre-closure rubber, and a final stage in which the machine applies the appropriate pair of closure on said covers.

More specifically, an upper frame is arranged on the Lower frame, in which a receiving hopper of the covers is arranged, which are supplied to a distributor mechanism through a broth ramp, being assisted by a mechanism of conventional feeding.

Thus, the distributor mechanism located at the exit of the ramp through which the covers are supplied, will present means of horizontal and vertical regulation to adjust to different widths and height of covers, including guiding means that stop the lid in a way that this is inclined and facing the mouth of the jars, so that these in their movement on the conveyor belt "steal" the covers, when the leading edge of its mouth comes into contact with them, being deposited on said mouths.

Together with this mechanism, the steam supply equipment is established which, as previously stated, will allow steam to be applied at a certain temperature in the mouth of the container to generate a vacuum effect once the lid has been placed and the assembly cooled.

After this system, the pre-closure assembly is established in which a rubber side shoe participates, on which the jar lid comes into contact in its automatic movement on the conveyor belt, a shoe that is retractable against the tension of a spring, and which will cause tangential contact with the cover with its rotation and consequent pre-closure, said mechanism being assisted with a tread pin intended to push said cover internally in the turning maneuvers thereof ensuring the closure Of the same.

Obviously, with this mechanism, an adequate closing torque is not achieved, therefore, following this, a closing unit is established in which a second vertical thrust pin is engaged, against the tension of a spring provided with means of regulation both in height and in pressure, and a mechanism for actuating a closing band, which acts tangentially on the cover, said mechanism being associated with a transmission by means of which the appropriate closing torque is applied to the cover, also counting this mechanism with height adjustment means to adapt to different types of jars.

Analogously, it is provided that the mechanism that supports the slide and the end rollers on which the closing band is circulated is assisted by a cam or articulated arm, assisted by a second spring, intended to absorb the thrust forces on the closure set.

Parallel to this structure, it is provided that the lower frame incorporates lateral belts arranged at the sides of the conveyor belt and at a certain height, which ensure the correct lateral stabilization of the containers during their movement along the conveyor belt, accompanying them in such displacement.

These elements include both horizontal and vertical adjustment means to adapt to different sizes of packages and ensure that the jars tangentially access the final closing mechanism intended to give it the appropriate tightening torque.

According to another of the characteristics of the invention, the conveyor belt, the side belts, as well as the closing mechanism will be assisted by a single motor, by means of the corresponding transmission / synchronization systems, thus simplifying the structure of the machine.

Preferred realization of the invention

In view of the figures summarized, it can be seen how the machine of the invention is constituted from a lower frame (1), which includes a single motor (2) for driving the different main mechanisms of the machine, lower frame (1) on which a conveyor belt (3) is arranged longitudinally, driven through the corresponding transmission (4) associated with the engine (2), on which the containers or jars to be closed are deposited.

Parallel to this structure, it is provided that the lower frame incorporates lateral belts (5-5 ') arranged on the sides of the conveyor belt (3), including height adjustment means (6), one of them being fixed in With respect to the side elevation, while the other (5 ') also incorporates horizontal regulation means (7), in order to allow adjusting the horizontal distance between the two straps to adjust to the width of the containers to be closed, ensuring the Correct lateral stabilization of the containers during their movement along the conveyor belt (3), accompanying them in said displacement.

The conveyor belt (3) crosses an upper housing (8) as a tunnel or upper frame on which a container container (9) of the covers is established associated with a feeder mechanism (10) that supplies them through a ramp (11), towards a distributor element (12), shown in detail in Figure 5.

This distributor element (12) includes a pair of parallel glues (13-13 '), whose width is adjusted to the diameter of the covers to be supplied, with a regulation screw (14) through which said width is adjusted this mechanism being locked by means of the fixing screws (15) In the same way, these glues (13-13 ') are displaced vertically with respect to the main body (16) of the distributor (12) by means of regulation screws (17).

In this way, the glues (13-13 ') have the covers fed from the tank (9) inclined to the mouth of the containers that advance through the conveyor belt (3), so that the displacement of the container causes the lid to be pulled by the leading edge of the mouth of said container and that it falls by simple gravity on it including said distributor mechanism then a pre-closing mechanism (18).

The pre-closing mechanism (18) consists of a rubber shoe (19), movable against the tension of a spring (20) and acting tangentially on the lid, so that the displacement of the container-lid assembly itself when they come into contact with this element, they cause the lid to be screwed on and consequently the "pre-closing" phase.

To ensure that the rotation caused by the tangential friction of the shoe (19) causes the correct helical closing movement, the mechanism is complemented by a tread plate (21) associated with two pairs of connecting rods (22) with respect to the body main (16) of the distributor, this mechanism being also assisted by a spring (23), equipped with means for regulating its hardness (24).

At this point, the containers are closed, but not to the proper closing torque, so that following this mechanism a closing mechanism (25) is established, the one shown in detail in Figure 6, in which a second participates vertical thrust pin (26), against the tension of a spring (27), provided with adjustment means (28) both in height and in pressure, and a mechanism of actuation of a closing band (29), which It acts tangentially on the lid, said mechanism being associated with a transmission (30) whereby the appropriate closing torque is applied to the lid, this mechanism also having height adjustment means (31) to adapt to different types of jars .

The mechanism that supports the slide (26) and the end rollers (32) on which the closing band (29) is circulated are assisted by a cam or articulated arm (33), assisted by a second spring (34) intended to absorb the thrust forces on the closure assembly.

The process of closing the containers is expected to be done in a steamy environment, in order to cause a vacuum effect after cooling the containers once closed.

To do this, steam is injected into the upper casing (8) through steam supply equipment (35) of any conventional type.

As stated previously, the conveyor belt (3), the side belts (5), as! as the closing mechanism (25) will be assisted by a single motor (2), by means of the corresponding transmission / synchronization systems thus simplifying! The structure of the machine.

Finally, say that the machine will present a user-friendly interface (36), with a start button (37), a stop button (38) and an emergency mushroom (39).
