Description

Refinements in the object of the patent 200102539 for `` Installation for manufacturing concrete parts armed''.

Main Patent 200102539 refers to a installation intended to manufacture reinforced concrete parts, comprising a succession of transports on which they are carried the pieces in continuous route from a formation stage to a stage of discharge already fully formed.

The first transport of the installation consists of on a metal conveyor belt, on which they are determined the molds of formation of the pieces to obtain, going in the part initial of the molding area a concrete discharge head necessary and a concrete adapter head in the molds.

The formation of the molds is determined with the metal conveyor belt as a base, the closure being established of retention in the lateral ones by means of bands that move of way synchronized with the metal tape, which bands sides are arranged, according to a solution, in relation to respective chains of magnets that maintain the union of said bands relative to the metal tape in the molding path of the pieces, with separation at the end of said route to return independently.

The second transport of the installation is a travel route of the pieces already demolished, during a expected time for drying them, taking them to the unloading area where the pieces are tilted up to a almost vertical position for removal by means of elevation.

In relation to all this, according to the This invention proposes improvements that improve the behavior and characteristics of the installation in the function Application practice.

According to these improvements object of the invention, the discharge head and the adapter head of the concrete in the molds of formation of the pieces, are arranged incorporated in a transverse displacement assembly with respect to of molding transport, in relation to respective cabins of washing said heads located on one side.

A provision is thus obtained in which the mentioned discharge and adaptation heads of concrete in the molds may be smaller than the transport of the molding, covering the width of this by displacement transverse, which determines that the surface to be clean of such heads is smaller.

Thanks to that smaller surface to clean of the heads, a dry cleaner is available in relation to them by scraper, which allows installation work without have to move the heads to the corresponding ones washing booths nothing more than every quite a while, so achieves a remarkable saving of water, reducing the amount of contaminated water resulting from washing.

The metal tape rests on the path of the molding transport on a lift chain that allows duly support the weight of molded parts in formation, returning the tape and the support chain independently by the bottom, resting on respective roller assemblies  sustainers, while the determining bands of side of the molds return in turn independently, staying attached to the respective magnet chains when They have them.

In that independent return provision of the moving elements, the metal tape is free of withholdings and charges, establishing in relation to it a driving guidance that corrects the lateral deviations that I can have the same.

The second transport of the installation, as well as  The exit zone for unloading parts are determined by means of a succession of support rollers in transport of the concrete parts, resulting in a strong support that allows to support with a very simple assembly arrangement weight of application parts.

In the area of exit of the pieces for the discharge, a frame is arranged whose structure is interspersed with respect to the support rollers of the pieces, independently of said rollers, said frame going in articulated assembly of tilting on one side, with drive means for said tilting; whereby the tilting of the pieces up the withdrawal position by lifting means, is performed by means of the accessory frame, the rollers of displacement of the pieces in that area, resulting in much more simple installation of the installation, since the means of tilt and means of moving parts are independent.

Between the second transport of the installation and the exit zone for the unloading of the pieces, a Supply of heat shrinkable plastic sheet, transversely with respect to the travel path of the pieces, so that when passing the pieces towards the exit zone they are wrapped by the heat shrinkable plastic sheet, which favors the conditions for the total setting of the concreting of the pieces in a short time during storage.

According to a particularity, the installation will also provides a water recirculation system that is used in the washing of concrete parts, as well as the water that is used for cleaning concrete elements, supplying these wastewater to the process of preparing the concrete to form the application parts, thereby it reduces the water consumption in the installation, at the same time as Eliminates the discharge of contaminated water.

The present invention relates to some improvements in the installation object of the Patent 200102539, intended for the manufacture of concrete parts armed, comprising a conveyor stage in which it is carried out the molded formation of concrete parts, one stage drying conveyor and a final stage of exit for the download of the pieces.

The molded formation stage of the pieces of concrete is formed by a conveyor belt (1) constituted by a metal sheet that extends in a closed path, running along a superior path that rests on a lift chain (2), which accompanies the belt (1) in its movement, returning both independently by the part bottom, supported on respective supporting rollers (3 and 4), as seen in figure 2.

On the metal tape (1) the forming molds for concrete parts (5), settling said molds with the metal tape itself (1) as background, while that in the vertical contour are defined by separators (6) that are placed by setting the front and rear limits, with containment closure on the sides by side bands (7).

The mentioned side bands (7) form their once a closed tour, in motion synchronized with the tape (1), with independent return with respect to it, as well as with respect to the support chain (2).

Said side bands (7) can recirculate in return from the outer side, as shown in figure 1, or well in return recirculation from the bottom, being planned its association with respect to respective magnet chains (8), for fixing on the metal tape (1) in the path of the molding transport, returning all the bands (7) and its magnet chains (8) in support of respective sets of supporting rollers (9), regardless of the belt (1) and of the chain (2), as seen in figure 8.

With that arrangement the metal tape (1) is in its lower part of return totally independent and free of charges, establishing in relation to it in that part a guided driver that corrects the lateral deviations of the same. Said guided driver is established by means of bearing bearings on the side edges of the belt (1) and by means of an optical cursor, by laser or any other means conventional, following a straight line of reference, which determines an automatic correction of deviations transverse, by thrust with bearing support on sides.

In the initial part of the molding transport of the pieces (5) goes a set of concreting, formed by a discharge head (10) of the necessary concrete and a head (11) adapter of the concrete in the molds, establishing said heads (10 and 11) arranged in a sliding assembly transversal with respect to molding transport, available for transfer to respective washing booths (12 and 13) located on one side, as seen in figure 1.

With that arrangement the heads (10 and 11) they can be of a width smaller than the molds formed on the metallic tape (1), since for the realization of concreting said heads (10 and 11) cover the width of the molds by its transverse displacement, which makes it possible to arrange some heads (10 and 11) of a very small operating surface.

That small dimension of the operating surface of the heads (10 and 11), makes them clean easily, providing a cleaner in relation to them dry by scraper, which allows thorough cleaning of those heads (10 and 11), by washing, in the respective cabins (12 and 13), just have to be done every quite time, thus achieving a remarkable water saving, at the same time as wastewater production is greatly reduced contaminated

The second transport of the installation, intended for drying concrete parts (5), as well as the exit zone for the discharge, are constituted, according to a form particular embodiment, as shown in Figure 3, by a succession of rollers (14), determining a rolling transport, on which the pieces (5) rest on their movement towards the discharge zone, with some of the rollers (14) with motorized drive, while the others they go in free spin assembly; the rollers (14) being motorized those that carry out the dragging of the pieces (5) for displacement, while others only support rolling.

In the exit area for the download, you have a frame (15), whose structure is interspersed between rollers (14) supporting the movement of parts (5), without interfere with said rollers (14), as shown in Figure 7, in where only two rollers (14) have been represented, but it is perfectly observed that the crossbars of the structure of the frame (15) are sandwiched between the positions of the assembly of the rollers (14) that will go in that part of the installation.

As seen in figures 5 and 6, the frame  (15) is articulated with respect to a rotating clamp (16) on one side, with actuator cylinders (17) which allow to activate a tilting of said frame (15) between a horizontal position, like the one in figure 5, and a position almost vertical, like the one in figure 6.

In the horizontal position (figure 5) the frame (15) is tucked into the upper plane of the rollers (14), so that the concrete parts (5) support said rollers and can move on them without any inconvenient to reach the discharge position.

When the pieces (5) reach the position of discharge, actuate the cylinders (17) by tilting the frame (15), which raises the part (5) that is in that area (figure 6), thus positioning the part (5) in a almost vertical situation, for the withdrawal of the same in subjection on one side with a crane-like lifting means, achieving said positioning of the piece (5) without the rollers of transport (14) move from position.

In the passage area from the drying transport at the discharge outlet, a laminar band supply is provided (18) heat shrinkable plastic, fed from a coil upper (19) and a lower coil (20), as shown in the figure 4, the laminar band (18) remaining transversely with respect to the travel path of the pieces (5), so that at pass said parts (5) to the discharge outlet wrapped by the aforementioned laminar band (18). With that wrap conditions that favor the total setting of the concreting of the pieces (5), in a short time, during the storage of them.

In the transition of the passage from the transport of dried to the discharge outlet, a water projector (21), to wash the underside of the pieces (5) when the finishing of these requires it; being planned in the installation a recirculation of the residual water of said washing of the parts (5), as well as the residual water of the washing of the heads (10 and 11) in the cabins (12 and 13), for sending said wastewater to the concrete manufacturing process necessary to form the pieces (5), which reduces the water consumption in the installation, eliminating both spills of contaminated wastewater, since the wastewater from the washes are used in the production of concrete formation of the pieces (5) to be carried out.
