Description

DOUBLE SQUARE EQUIPMENT AND PROCEDURE FOR SIDE MACHINING OF STACKED RIGID MATERIALS

Technical sector

The invention that is protected in this Utility Model, consists of a squaring equipment and procedure to form right angles on all its faces according to the required shapes (rectangles, squares, hexagons, etc.) on machinable rigid materials (wood, plastics , corks, etc.), finding all the pieces to be treated in a stacked or block assembly. These machining are common in the manufacturing processes of wood, plastic and resin boards, cork and aluminum to achieve pieces for the furniture, packaging, or construction sector, among many others.

Prior art

At present, squaring machines and procedures are already known and used, but all of them present both operational and functional problems, especially due to the volume of waste generated that entails the loss of parts (chips or surplus material); whereby the use of the means already developed always have certain limitations against the invention presented. Thus, they are of conventional use the squared by drag of piece to piece through belts or chains that pass between two circular saws that cut the material. For this, it is usually customary to pass both piece by piece, and at the same time proceed to more than one squad pass of the materials worked. Examples of squad system inventions used are the German patent DE 10237206 ZERFASS HEINZ (2004) on an "L" shaped device that works piece by piece as common techniques, or European patent EP 1815954 BIESSE (2007) on a square bench bracket also piece by piece of board or square material.

This results in functional and operational limitations, and therefore far from the device of the invention, especially due to the use of materials and the simplification of technical means.

Technical problem

Current squaring techniques by way of dragging or moving the tool over the material, has the following characteristics:

- Lower productivity because the square is made piece by piece against the stacking or block proposed. In addition, inaccuracies in the squad may result.

- Less operability because the piece by piece squared must be stacked after the effects of stockage and storage

- Need for secondary procedures as there are also chips that must be used for crushing processes.

- Requirement of an auxiliary cleaning process on the machinery when generating loose and uncontrolled chips.

Greater requirement of operators in their manipulation to square and stack for storage, because they are manual feeding processes. Technical solution In front of a simple drag by squaring horizontally by conveyor belt, or vertically with a vacuum block where the squaring tool is moved (saw or tupi profiler) and where the piece is locked and stopped, a piece is raised squaring means where there is a continuous movement of the piece that despite being locked rotates on its own axis in the squad maneuvers.

Thus, through a conveyor belt, the piece (blocks) is moved to a rotating table where first, locking stops center the piece vertically and horizontally, and secondly, they direct that table with the block of pieces towards one or more sets of parallel and opposing milling machines - double squaring aspect -, making one or more turns depending on the number of milling machines or the faces to square in the form of the desired pieces (rectangle, octagon, hexagon, etc.) since the turntable allows movement 360 ⁰ sexagesimal radio.

Advantageous effects

Its main advantage lies in its productivity and its energy efficiency due to the work of stacked and block parts that maximize its operability and work capacity.

It is also an automated system that exempts from direct manual intervention in the squaring process itself, thus reducing the number of operators. There is an economy of scale when working in block and not for loose and isolated pieces. Consequently, there is greater production in a shorter working time. And this, in pieces of minimum thickness up to a maximum of 2 meters high. While in width, it is able to work according to the standard market measures for boards or materials.

With respect to the final treatments of the squaring, the suppression of the stacking of the squared pieces will be achieved by being all machined in block at once. Not requiring such subsequent function. And in addition, this favors and facilitates its arrangement for packaging with contoured elastic plastic. And likewise, the production of splinters by cutting circular saw is eliminated by being squared by means of cylindrical tools arranged vertically with simultaneous effect of cutting and crushing of their waste.

How to carry out the invention

Stacked pieces of rigid materials to work up to a height of two meters are deposited on a block entrance bench (3), whose conveyor belt - chains, belts or belt - moves the block to a rotating-rotating table (4) , which pressed by a vertical immobilizer stop (10) moves it to the centering stops (6) where it is perfectly centered around the imaginary axis of the rotary-rotating block table (4). It is the so-called first block centering movement. Then, the block-rotating table of blocks (4), once centered and immobilized next to its block by the horizontal immobilizer stops (7) together with the vertical immobilizer stop (10) - which is the second movement called the movement of block immobilization - it carries out a translational movement on a sliding table sliding bench (1) by means of prismatic guides and linear skates to recirculating ball bearings driven through a servo motor with reducer - by belt, chain transmission, or rack and pinion -, which directs it towards a set of vertical milling heads (2) containing a cylindrical tool (9) and its motor (8) each, arranged in parallel and equidistant between the bed of sliding table slide (1). In the first set of vertical milling head (2) or primary milling machine, two lateral faces of the blocks carried by the rotary-rotating table of blocks (4) are outlined, and which, once exceeded and maintaining the continuous movement of translation, will perform a rotating movement of 90 ⁰ radius before entering the second set of vertical milling head (2) or secondary milling machine to have the four sides of the block worked. Through there it is subsequently directed towards the block exit bench (5), for final packaging and storage. For example, to carve a rectangle or square figure of the faces of the block.

Although, depending on the geometric shape to be obtained from the blocks and required by the user, it is possible to obtain larger block figures such as circular, triangular, hexagonal, octagonal, etc. based on the controlled rotation assigned to said table on a rotation of the translation-rotating table of blocks (4) between 0 - 360 ° radius. Logically, in a 360 ° assigned rotation a completely circular figure of the block would be achieved.

In addition, sets of vertical milling heads (2), block centering stops (6), and horizontal block immobilizer stops (7), are movable in width in order, according to user requirements, power control in a controlled way shapes and geometric configurations as well as free forms of the lateral faces of the blocks, such as for example sinuous figures. In this case, the advance and rotation of the translation-rotating table of blocks (4) can be interpolated with the opening and closing of the vertical milling heads (2). It is possible another embodiment of the invention that is presented with the same technical functions, but with a simplification of technical means using a single and single set of vertical milling head (2), and not double, performing how many movements of table translation of translation-rotating blocks (4) are necessary in advances and setbacks on the sliding table sliding bench (1) and the aforementioned head set, based on the desired figures and shapes.

Finally, on the contrary, and according to work needs, more than two sets of vertical milling head (2) can be added, as well as more than one block entry bench (3), and more than one block exit bench (5) expanding the capacity of the team.
