Description

Improvements introduced in the object of the patent No. P 200001338 by: "Improved jet cutting equipment Water".

The present Additional Patent application It consists as indicated in its statement on improvements introduced in the object of patent No. 200001338 for "Improved equipment of water jet cutting ", whose new characteristics of construction, conformation and design fulfill the mission for which It has been specifically projected, with safety and efficacy maximum.

In the main patent a team was described perfected water jet cutting with a means of suction by suction of waste material mainly comprising an air suction duct located at the bottom of each work table (the preparation table and the cutting one), connected to a water collecting duct and waste material, and finally a central suction duct of air equipped with an exhaust fan at its end whose function is to vacuum waste materials and avoid clogging of waste material.

Both the water and material collecting duct  of waste as the central suction duct run in its mostly horizontally down the bottom of the tables work and below the two air suction ducts, to properly drag waste materials from the operation of cut.

In particular, the invention relates to some changes introduced to the central air intake system of the cutting equipment, which in the main patent nº 200001338 the same owner was available as mentioned previously by the bottom of the team, while in the This version is located at the top of the team.

This version of the central vacuum system of the air has the great advantage that, fulfilling the same function of sucking the leftover materials from the cutting operation: the air, water and waste material than the main patent, also allows the water vapor generated during the water jet cutting operation, which is very difficult to evacuate

Another of the functionalities of this invention is to improve the grip of the piece to be cut against the negative of the same, which is achieved thanks to the location of the central air intake system at the top, of so that the direction and direction of the suction flow is vertical. Therefore, by increasing the grip of the part the operation of Cut improves substantially.

To achieve these functions, a suction system of the cut material on a cutting table arranged inside a cabin by air suction, with the particularity that the cutting and preparation tables are arranged in an inclined position with respect to the horizontal plane, thanks to the forecast of some pistons in collaboration with some arms articulated, and the air suction ducts are arranged from the water and scrap collection trays of each of the tables facing up until both ducts meet in a water collecting duct that runs vertically upwards. A central air intake duct with a fan extractor at its end end connects to the mentioned duct water collector to exert suction and also runs through the top and upright.

The cutting and preparation tables of the equipment They are adjustable in inclination thanks to the action of some cylinders that articulate an arm attached to each of the tables and the degree of inclination can range between values 0 and 90º degrees relative to the horizontal.

The inclination of these tables favors the suction of waste materials and water, since the direction of the suction flow until reaching the vertical direction it has a lower curvature than if they were in position horizontal and therefore lower load losses.

The trays of each of the tables of the team  They have a funnel shape and are arranged in the same address as the tables and have the function of collecting and properly channel water and waste material to air suction ducts.

The recommended cutting equipment is projected Especially for use in jet cutting equipment high pressure water of small thickness sheets of various materials; however, it can also be used in other similar applications for the same purpose without altering the essence of the invention, such as laser cutting, in which there are also waste materials that must be suctioned out.

Other details and features will go away showing in the course of the description that given below, in which reference is made to the drawings that this memory is accompanied in which the different parts of the recommended equipment, for illustrative purposes but not limiting the invention.

In one of the preferred embodiments of what  it is the object of the present improvements, and as can be seen in Figure 1, conceptually speaking the cutting team retains its specific nature, for understanding two tables of work (3 and 7) located inside a cutting cabin (4) that are interchangeable by means of a turning system and are provided of an air suction system formed by two ducts (10-11) connected by means of gates to a water collector duct and waste material (12), being said collecting duct (12) connected to a central duct of suction (13) provided in turn with a Extractor fan.

As it is a solution known by the patent of  origin, the two air suction ducts, the central duct suction and the collecting duct are located at the bottom of the work tables, so that the direction and sense of air flow is in the first section substantially vertical towards down to the ground level and in the second section totally horizontal

The previous solution without being considered Technologically deficient, it has been replaced by another type of disposal of the suction system in which the ducts of air suction (10-11), the central duct of suction (13) and the collecting duct (12) are located above of the height of the work tables, so that the direction and direction of airflow is vertical upwards, instead of horizontal.

As can be seen in figures no. 1-3, the cutting equipment is composed of a cabin (4) within which a robot (2) is placed attached to a support (26) and provided with a nozzle (1), which projects a water jet or laser directed to cut a piece (6) arranged  on top of a cutting table (3). Two tables of work, one of cut (3) and another of preparation (7), to minimize to the maximum the time invested in evacuating the finished piece and provision the next part (8), exchanging the position of the mentioned tables (3 and 7) just by turning the structure (5) around its axis (9) thanks to the motor driving action (19).

Referring to figure 2, each table (3 and 7) provide a tray at the bottom (24-25) of collection of waste material and water from the cutting operation as a funnel that communicates with the respective conduit of air suction (10-11). Both suction ducts of air (10-11) are arranged upwards with any possible arrangement and connected to a collector selector (33), which according to the table you are working opens a conduit and close the other by means of some gates.

These work tables (3 and 7) are located slightly inclined with respect to the horizontal plane, preferably about 45º, to optimize the air flow up and avoid abrupt changes in flow direction that would affect negatively to the efficiency of the suction system. For that end a piston (16) is incorporated per table joined by one of its ends to the table (3 or 7) by means of an articulated arm (17) and by the another to the structure (5).

The chosen solution of aspiration of the material cut comprises two sections of air suction (10-11) arranged from the respective trays (24-25) in the vertical direction until it converges on the selector manifold (33), selecting the working duct by opening and closing some gates (20-21) provided in the selector manifold (33). In Figure 3 shows the two gates (20-21) actuated by the respective cylinders (22-23). Following the mentioned conduit selector (33) there is a vertical section of water collecting duct and waste (12) that will preferably be poured into a tank, not shown in the figures, with the help of an extraction pump. The suction of these materials is done through a conduit central vacuum (13) also arranged in vertical direction up and connected to the conduit (12), extending horizontally in a section (27) that flows through a access opening (28) to an extractor fan (14).

Said system of ventilation-extraction of the air is formed by a fan body (29) of substantially cylindrical configuration within which a grid (30) is arranged for filtering the particles and at the top an outlet duct (31) that communicates with the extractor (32), as seen in the Figures 1 and 3.

Referring to figure 5, the circuit of air of the suction system object of the present invention runs from a position perpendicular to the table (3 or 7), towards up, to a fully vertical position in the direction ascending, and in a second section in horizontal position until the fan-extractor (14), as represented by air flow of the cutting table (34) and the preparation table (35).

Figure 4 shows the direction and direction of air flow over the entire surface of the table cut (34) to the selector manifold (33).

This particular circulation of suction air in an upward direction allows the steam to be sucked from water generated during the cutting operation and also improve the grip the piece to be cut against the negative of the piece.

Described sufficiently what is the Present Additional Patent in correspondence with the drawings Attached, it is understood that they may be introduced therein any modification of detail deemed convenient, as long as the recommended variations do not alter the essence of the patent that is summarized in the following claims.
