Definitions

  • the present invention relates to a method for cutting square or rectangular windows in so-called "master key” frames, intended for artistic framing, of the kind consisting in making on a cardboard blank two first perpendicular cuts corresponding to two adjacent sides of the window, then to make on the blank two other perpendicular cuts also corresponding to two adjacent sides of the window.
  • the invention also relates to a mechanized device specially designed for the implementation of this cutting process.
  • the cutting of the window (2) has so far been carried out using an apparatus making only one cut at each operation, as described for example in document US-A-3,779,119.
  • This device the principle of which is recalled in FIG. 1 of the appended drawing, has a blade holder sliding manually on a rail, for the displacement of a single blade (3).
  • the apparatus further includes a presser, an adjustable stop rule (4) for changing the margin width, and blade displacement stops (3).
  • the blank (1) is again released, and stored in the semi-worked state of two parallel cuts (ab and cd), with all the other blanks of the same series which must be cut to the same dimensions.
  • the same process is repeated to make two parallel cuts (ad then cb ).
  • the cardboard quadrilateral (abcd) delimited by the four cut lines made can then be removed, thus clearing the window (2).
  • the total cutting of the window therefore requires two manual phases, with two generally distinct adjustments and for each of the phases a reversal of the cardboard blank (1). To these operations are added the manipulations necessary for the storage and destocking of semi-finished products, between the two manufacturing phases.
  • the cutting means which make two perpendicular cuts simultaneously, can be moved here on the two branches of a movable square, placed in a first position to make the first two cuts, then moved to a second position rotated 180 ° by compared to the previous one, before making the other two cuts, which requires handling with disassembly and reassembly, and takes time.
  • document US-A-4,098,160 provides for a system for locating and positioning relative to a central point, which is not very rational and requires accessory devices.
  • the invention aims to eliminate all these drawbacks, by providing a method and a mechanized apparatus for cutting square or rectangular windows, for obtaining "master keys from solid cardboard blanks, which simplify and accelerate the cutting of windows while minimizing the intermediate manipulations, and which thus make this cutting more rational and more economical, in particular for the implementation of large series.
  • the cardboard blank being initially positioned on a flat work surface characterized in that the top of an angle of the future window is made to coincide with a fixed reference point, the first two perpendicular cuts are then made, and the blank is then turned over on the working surface to perform a similar positioning, in which the apex of the window angle opposite to the previous one coincides with the same fixed reference point, after which the last two cuts are made.
  • the window is thus completely cut out without intermediate storage, nor resumption of adjustments, nor additional manipulations. Marking and positioning are carried out with respect to a fixed reference point which coincides with an angle of the window to be cut and which is also used as the origin of the adjustment of the margins in the two perpendicular directions of the frame, and as the origin of the adjustment of the stroke of the cutting means along the length and width (possibly equal) of the window.
  • the mechanized apparatus for cutting window frames intended for implementing the method defined above, comprises in known manner, above a table constituting a flat working surface, two cutting means, the respective supports are movable in translation in two perpendicular directions.
  • the respective supports of the two cutting means are movable in translation along respective guides arranged in a fixed position on the table and defining for the two cutting means perpendicular trajectories which compete at a fixed reference point, and the apparatus further comprises means for positioning the blanks to be cut on the table with respect to the fixed reference point.
  • the respective supports of the two cutting means are moved alternately in perpendicular directions, along the respective guides, by means of translation jacks, for example pneumatic.
  • the apparatus includes a margin adjustment stop positioned relative to the fixed reference point and formed by a movable bracket, one branch of which is slidably mounted on the table, and the other branch of which is slidably mounted on the first , the two branches of the bracket being respectively parallel to the directions of the translation guides of the supports of the cutting means.
  • the control of the two jacks must of course be synchronized in such a way that the second cutting means arrives at the end of the travel at the fixed reference point while the first cutting means, previously arrived at the same fixed point, is already brought back from this point.
  • the translation guides carry movable tabs constituting the adjustable stops at the end of the travel of the two aforementioned jacks, therefore of the two cutting means.
  • the cutting means are blades
  • the device is also equipped with a square-shaped presser, actuated by a jack capable of bringing it closer or away from the work surface, the two branches of this presser being parallel respectively to the directions of the guides. for translating the supports of the cutting means.
  • FIG. 2 of the appended schematic drawing representing, in perspective, an embodiment of this device.
  • the mechanized apparatus according to the invention for cutting window frames includes a table (5) provided with legs (6) and offering a flat working surface.
  • Two supports (7, 8) fixed to the ends of the table (5) maintain above this table sliding guides longitu-. dinals. (9). Between these guides (9) and a lateral support (10) are also fixed, also above the table (5), transverse sliding guides (11).
  • a first pneumatic translation cylinder (12) has its rod fixed to the support (10), while its body is mobile and slides along the transverse guides (11) at its ends.
  • the bottom of the jack (12) constitutes a support (13) for a first cutting blade (14).
  • the blade (14) is mounted on its sliding support (13) by means of a jack (15) ensuring its penetration into the carton.
  • On one of the guides (11) is mounted, in an adjustable position, a cleat (16) constituting an end-of-travel stop for the translation cylinder (12).
  • a second pneumatic translation cylinder (17) has its rod fixed to the support (7), while its body is mobile and slides along the longitudinal guides (9) at its ends.
  • the bottom of the jack (17) constitutes a support (18) for a second cutting blade (19).
  • the blade (19) is also mounted on its sliding support (18) by means of a jack ensuring its penetration into the carton, this latter jack not being visible in FIG. 2 but being similar to the jack (15) .
  • On one of the guides (9) is also mounted, in an adjustable position, a cleat (20) constituting an end-of-travel stop for the translation cylinder (17).
  • the device is equipped with a bracket (21) for adjusting the margins, formed by two movable branches (22, 23).
  • the first branch (22) extends longitudinally, in a direction parallel to that of the first sliding guides (9).
  • This first branch (22) is slidably mounted in a transverse direction, by its ends which move along grooves (24) hollowed out - at the ends of the table (5), locking means (25) making it possible to immobilize it in the desired position.
  • the second branch (23) of the bracket (21) extends, perpendicular to the first branch (22), in a direction parallel to that of the transverse sliding guides (11); this second branch (23) is slidably mounted on the first branch (22), and it comprises a locking means (26) making it possible to immobilize it in the chosen position.
  • the apparatus further comprises a pressing device (29), comprising a bracket whose two branches (30, 31) are respectively parallel to the directions of the translation guides (9, 11).
  • This bracket allowing the cardboard blank (1) to be maintained during the cutting operation, is actuated by a jack, not shown, acting on a vertical rod (32) integral with said bracket, this jack being fixed at the intersection of the bars.
  • a jack not shown, acting on a vertical rod (32) integral with said bracket, this jack being fixed at the intersection of the bars.
  • horizontal of two brackets (33, 34) - fixed to the table (5).
  • the electro-pneumatic equipment used for feeding and controlling the various jacks can be supported by the base of the table (5), in order to clear the entire working surface.
  • a cardboard blank (1) is brought onto the table (5) and positioned by applying two of its sides against the two branches (22, 23) of the bracket (21).
  • the presser (29) is lowered to maintain the blank (1) in this position, then the two blades (14,19) are actuated by the jacks (12, 15, 17), so as to make the first two cuts along adjacent sides of the future window (2), namely a width (EO) and a length (FO).
  • EO width
  • FO length
  • a suitable offset in the actuation of the jacks allows the second blade (19), for example, to arrive at the reference point (O) while the first blade (14) is already back.
  • the blank (1) already comprising two cutouts is turned over and again positioned on the table (5) against the bracket (21), so as to coincide with the fixed reference point ( O) the point (O ') which corresponds to the top of the future window opposite the angle already cut.
  • the presser (29.) is put back in place and the two blades (14, 19) are put back into action as before, to cut the second width (FO ') and the second length (EO'). The total cutting of the window (2) is thus obtained.
  • the respective supports (13, 18) of the two cutting blades (14, 19) include the possibility of bevel cuts as of cuts orthogonal to the plane of the blank (1).
