TECHNICAL FIELD DB IA INVENTION

The present invention relates to the technical field of mechanics, since it provides a mechanism to position and place threaded caps continuously.

BACKGROUND OF XA INVENTION

The history of packaging materials goes back eight thousand years ago, when man began to store his food and objects in clay pots, although they had no thermal process, they could already be used to contain, protect and store. The man begins the development of glass as a packaging material, probably with a novel application of high temperature cooked ceramics. Subsequently, a flourishing glass packaging industry for beverages and perfumes begins in Egypt, from where these products were exported to all the countries of the Mediterranean basin. About seven thousand years passed until the invention of printing and paper and with it the first bases of packaging engineering. When labeling begins, the improvement in the use of glass containers, as protective and selling elements, begins. In 1700, the champagne industry started in glass bottles with cork stoppers, capable of withstanding high pressures. A century later, the canned sector packages jams in wide-mouth glass containers. For the year of 1890 the first bottles for milk packaging are introduced (thanks to Luis Pasteur), the first brands of whiskey packed in glass and the first carbonated drinks are also introduced in glass containers. During the 20th century, mayonnaise packaging begins, perfumes use very creative packaging, baby food is They sell in glass, the machinery for the production of packaging is greatly improved. In the 20th century, a new packaging material, plastic, was also born. For this reason, machines that carry out the packaging process, applied to the food and beverage industry, the cosmetics industry and the pharmaceutical industry have been invented over time.

The containers applied to all industries worldwide, have the most varied sizes and shapes, and consequently their caps are presented with the same variety. The cappers allow you to safely apply all the usual types of caps from the screw caps of plastic, aluminum, crown caps, twist-off, ring-pull, to natural corks. There are also cappers that are used for very special cap models that fit exactly those requirements. At the beginning of the 21st century, all areas of knowledge and arts congregate in the proper design of packaging. New materials and techniques are developed every day, which creates a technological competence in search of perfect material for the benefit of a better standard of living and the optimization of the production and marketing processes in the world industry, for example, mechanisms that place the lids on containers, such as taparrosca cappers.

A technical search was carried out on a mechanism to position and place screw caps continuously and the patent application number EP2170757 (A2) was published, published on April 7, 2010, which is entitled "A PLUG MACHINE", this application describes a capping machine comprising: a shaft that rotates on a fixed base frame around an axis of rotation in an upright position; It contains several plugging units arranged radially and coupled to rotate together with the shaft around said axis of rotation, a cylindrical cam intercalated between the shaft and the plugging units, whereby each of the units they approach and move away from the fixed base frame, characterized by the fact that it is moved by a support element that is attached to the base frame, housed inside the rotating shaft and connected to the cam, whereby said cam is held in a fixed position default with respect to the base frame.

On the other hand, the German patent application was found under the number DE2802312 (Al), published on July 26, 1979, which describes a laminated tool that acts against the lateral presses of the bushing, which in turn hold the neck Of the bottle. A sleeve fits around a push rod that rotates with the spindle, and slides at a right angle to the push shaft, secured by fixing screws on the push rod. The rolled tool is mounted on the lower end of the sleeve and in the resting thrust position, the sleeve is coaxial, when the pushrod which is eccentric thereto is lowered.

Another document found is patent application number ES2243653 (Al) entitled "PLUG MACHINE WITH A PLUG HEAD" and which was published on January 8, 2003, said patent application describes a capping machine with a capping head that is intended to be placed caps in containers, in particular bottles or the like, and which is removably attached by means of a hollow sleeve, coupled to said machine through fastening means comprising at least a first element, mechanically attached to said sleeve, and to the less a second element mechanically connected to the upper part of said head, being able to be movably coupled together by means of quick adjustment gears. Said machine comprises drive means capable of rotating around a central axis of the head, to fix a cap on the top of a container, retaining it therein by means of a threaded connection, and characterized by said drive means forming a thread in said plug, which It compresses the lateral surface thereof against a finish of the mouth of the containers and for being coaxially arranged push-rod-shaped means within the same head and said hollow sleeve and are actuated to press the cap against the mouth of the container.

Finally, the patent application with number EP1905728 (Al) was found; which describes a closing head for an automatic encapsulator, which includes a movable support in vertical position for raising and lowering, a rotating shaft transported by said support, movable together with the latter vertically and with rotation with respect to the vertical axis and a The capsule gripping member transported to the lower end of said rotating shaft is characterized in that it includes a fixed sleeve in relation to said support and coaxial with respect to said rotating shaft which forms around a chamber containing a sanitation liquid.

As can be seen in the documents described above, the devices have multiple parts and do not have the possibility of using only two removable parts that are installed in a machine to put the screw cap on a bottle; nor do they describe the ease of being able to be easily removed from the machine, to reduce the preparation time to be able to adapt to the sizes of the screw caps that will be placed in the bottles which gives it the flexibility of being able to place different screw caps size, also do not describe that the process of placing screw caps is simplified one in a single mechanism, which allows it to be continuous and the path of the bottle does not have to be interrupted to place the screw cap and then screw up considerably reducing operating times , nor do they allow the process to be more agile, and with ease of machine maintenance. OBJECT OF XA INVENTION

DETAILED DESCRIPTION OF THE INVENTION

For a better understanding of the invention, the parts that make up the mechanism to position and place screw caps continuously are listed below:

1. Stem

2. Plunger

3. Non-skid

4. Given

5. Slot

6. Means of detention

7. Hole

With reference to figures 1, 2, 3 and 7, the mechanism for positioning and placing screw caps continuously consists of a rod (1), which at one of its ends is connected with a plunger (2) that has at the end a layer of non-skid material (3), said non-skid material is configured with a hole (7) in its center, which allows to place flat and / or conical threaded caps, as illustrated in Figure 8. A die (4) configured to receive inside the plunger

(3), said die (4) is which preferably cylindrical, and has a groove (5), through which the screw caps that will be placed in the bottles are introduced, thanks to a channel (not shown) placed in the position of the groove (5).

To prevent the screw cap from leaving before the bottle is in the receiving position, the die (4) has at least two stopping means (6) inside, as illustrated in figures 4, 5, 6 and 7, said stopping means consist of a spring (not illustrated) that drives a ball, which prevents the threaded cap from continuing its travel through the die

(4), and also prevents, that the screw cap has movement inside the die (4), allowing it to fall directly and perpendicularly to the neck or crown of the bottle where it will be placed, thereby reducing the defects of a bad thread.

PREFERRED REALIZATION OF THE IHVENSIOM

The following example illustrates a preferred way of how to carry out the embodiment of the present invention, and therefore should not be considered as limiting it.

Example 1: Illustrate how a screw cap is placed in a bottle thanks to the mechanism for positioning and positioning caps continuously

The mechanism for positioning and placing screw caps continuously, as shown in the figures, is mounted by means of the rod (1), on the opposite side of the piston (2) in a machine with a hexagonal arrow with motor, which allows adjustments in the axes x, yy / or z.

A channel (not illustrated) that contains the screw caps that will be placed in the necks or crowns of the bottles, is installed in the groove (5), allowing a threaded cap to enter inside, and stop thanks to the stopping means (6), waiting for the bottle that will receive the threaded cap to be under the die (4) at a separation thereof equivalent to half the size of the screw cap to be placed.

Once the bottle is in position, the rod (1) is driven by the engine, causing it to turn and lower at a programmed speed, allowing the plunger (2) to enter the die (4) until it makes contact with the screw cap and release it from the stopping means (6), and thanks to the non-skid material (3) it makes the screw cap rotate continuously until it reaches the neck or crown of the bottle and close the bottle.

Subsequently, the rod (1) rises to the initial position, causing the piston (2) to exit the die (4), allowing one more screw cap to be inserted through the groove, until it is stopped by the stopping means (6 ) and the process described above is repeated.

This process is done in less time than those already known.
