Description

Machine for mass production of parts plaster and related materials.

Object of the invention

The present invention patent application Its purpose is to register a machine for manufacturing in series of plaster parts and related materials such as cornices, moldings, partitions, shelves, hoops, florists, curtains, friezes, etc., which incorporates notable innovations and advantages compared to the current machines or devices used for same end.

More specifically, the machine of the present invention makes the pieces, forged, come out longitudinally with respect to the advance of the band that houses the molds, being collected and subsequently stored.

Background of the invention

Currently the industry specialized in Manufacturing field of plaster parts or materials similar, they use machinery for molding them in Serie.

Said molding consists of the pouring of the plaster or similar material, in a liquid state, inside the molds that houses the conveyor belt; after a while prudential for the setting of the pieces, we proceed to unmold them, either manually or automatically, the latter being high cost.

The arrangement of the molds in the band carrier of them, it is in such a way that the pieces come out in transverse position to the advance of the band, therefore presenting a great inconvenience, because a fairly high percentage of these pieces break when unmolding and reach the exit where they are collected or deposited, usually on tables or surfaces of pick up These ruptures are due to the space between the carrier band and pickup element. For that space the piece makes a slight jump that when falling generates cracks and ruptures in the pieces, either slide or hook through this space, causing all this economic losses.

Description of the invention

The machine for mass production of parts of plaster and related materials object of this register, eliminates the aforementioned problem, since the pieces obtained do not suffer breakage or deterioration when leaving the conveyor belt.

The machine of the present invention is characterized by being a series of modules chain couplings such as a drive module, a tension module and a certain number of intermediate band guide modules and chain, according to manufacturing needs.

In turn, the machine features a band conveyor, arranged longitudinally, circulating between a Drive drum and tensioner drum.

On the outer face of said band are coupled flexible rubber or rubber molds, parts conveyors of plaster or related material. These molds are arranged longitudinally with respect to the advance of the band conveyor

The modules mentioned above are the module motor in which the motor drum is located, which is driven by an electric gear motor, which drags the conveyor belt; the tension module, opposite the anterior, which comprises a belt tensioning drum, being mounted on bearings with their corresponding screws adjustment and regulation; and the intermediate modules that determine the greater or lesser length of the machine, depending on the time necessary that must pass for the setting of the pieces.

The demoulding of the pieces and their corresponding Conveyor belt output is performed on the drive module. The band returns through the bottom of the structure, following the contour of the driving drum, so the molds are arched separating from the pieces, and these are collected by a table, generally of glass, or element related to said function as rollers, ribbons or sheets.

Specifically the use of the glass table, which it is mounted on an armor, it facilitates the sliding of the pieces to prevent deterioration.

Finally, the band, on its return by the party bottom of the structure, find some support rollers both at its exit from the driving drum as at the entrance to the drum tensioner, to facilitate said operation.

Thanks to the longitudinal positioning of the molds of the pieces in the band, which allow the output of pointed pieces and their collection table, you get reduce and eliminate the deterioration or breakage of the pieces, since These are collected gradually to their demoulding.

To complete the description that follows will perform and in order to help a better understanding of their characteristics, is accompanied by the present specification, of a set of planes in whose figures, illustratively and not limiting, the most significant details of the invention.

Description of a preferred embodiment

In view of the commented figures and agree with the numbering adopted, you can see in them a preferred but not limited embodiment of the invention, the which consists of a machine for mass production of parts of plaster and related materials which is constituted by a series of attachable modules in chain such as a drive module (2), a tension module (3) and a certain number of modules intermediate (1) band and chain guide.

In turn, the machine features a band conveyor (9), arranged longitudinally, circulating between a driving drum (4) and a tension drum (6).

On the outer face of said band (9) are coupled with flexible rubber or rubber molds (10), conveyors of plaster pieces (11) or related material. Sayings molds (10) are arranged longitudinally with respect to the advance of the conveyor belt (9).

In the drive module (2) is the drum motor (4), which is driven by an electric motor reducer (5); the tensioner module (3), in opposite position to the previous one, it comprises a tension drum (6) of the band (9), and is mounted on some bearings (7) with their corresponding screws adjustment and regulation; and the intermediate modules (1) that determine the greater or lesser length of the machine.

On the other hand, a table (12) mounted on a armor (13) collects the pieces (11) demould, being this arranged in the area near the drive module (2).

Finally, the band (9), on its return, find some support rollers (8) both at its drum outlet motor (4) as at the entrance in the tension drum (3).
