Definitions

  • This invention refers to an improved flanging machine, designed in particular to process the opposite edges of panels or the like, holding two separate tooling assemblies capable of performing the milling and/or rounding of the panel's front and rear edges during its forward motion.
  • the milling assemblies move along with the panel, but are sliding on an inclined plane and subject to the action of a linkage that controls the rotation of the milling assembly along a path corresponding to a profile to be realized on the edge of the panel.
  • the characteristics of the flanging machine allow achieving a more precise motion of the tool, as well as controlling its sliding speed, so that the latter moves faster at the beginning and at the end of the processing operation.
  • the panels manufactured for instance from enhanced hardboard or the like are usually finished by applying heavy wooden edges, which are then rounded off based on profiles varied from time to time, so as to achieve for instance a semicircular edge, or a flat edge with rounded corners.
  • the Italian patent no. 1.295.377 of the same applicant describes a flanging machine equipped with a profiling device comprising some means capable of engaging a milling tool with the panel edge, other means for controlling the forward sliding of this tool along with the panel, and additional means to impart to the latter a trajectory befitting the profile to be generated on the panel.
  • this known flanging machine includes a tooling assembly installed on a support which is in turn mounted on a trolley sliding along a rail set up in a direction parallel to the forward motion of the panels and equipped with a motorized chain attached to said support, that engages a toothed element firmly attached to the same support so as to simultaneously control both its rotation and forward motion on said trolley.
  • This invention now enters the same branch. It proposes an improved flanging machine comprising two separate tooling assemblies designed to process a panel's front and rear edge, respectively, and to move along a plane inclined with respect to the forward motion of the panel, under the action of a linkage which controls the rotation so as to force the tool, with extreme precision, to follow a path befitting the profile to be achieved on the panel.
  • the flanging machine comprises two milling assemblies, identified by the reference numbers 1 and 2, respectively, the first being designed to process the front edge and the second to work the rear edge of a panel illustrated in a simplified form and marked by the number 3, while advancing in the direction of the arrow F.
  • each milling assembly is assembled twice, first in its starting position and then in its final processing position.
  • Each assembly comprises a tool indicated by the number 4 in Figure 2, actuated by a motor 5 and mounted on a support 6 sliding along a guide on recirculating rollers 7, which is mounted on the inclined plane 8.
  • the shifting motions of the support 6 along the guide 7 are controlled by an electric motor 9, preferably a brushless motor actuating a screw on recirculating rollers 10, on which a nut screw 11 solidly attached to the support 6 is allowed to slide.
  • an electric motor 9 preferably a brushless motor actuating a screw on recirculating rollers 10, on which a nut screw 11 solidly attached to the support 6 is allowed to slide.
  • the nut screw is also illustrated twice in the Figures 4 and 5, in the tool's initial and final positions, respectively.
  • the support 6 ( Figure 3) is solidly attached to a crank 12, hinged to a connecting rod 13 which is in turn hinged on its opposite side to a fixed arm 14, attached to the inclined support 8.
  • the lever connected to the milling assembly is arranged so as to control the rotation of its relative support in one direction, in this figure for example in a counterclockwise sense, while the lever 13 connected to the assembly 4 (refer to Figure 4) is positioned so as to control its rotation in an opposite direction, in this figure in a clockwise sense.
  • the crank 12 is firmly attached to a ring gear 20, connected by a chain 21 to a another ring gear 22 which is in turn firmly attached to the support 6.
  • the ratio between the ring gears 20 and 22 is such that the ring gear 22 completes a larger rotation with respect to that of the ring gear 20, at a ratio of 1:1.3, for example.
  • the result is to achieve a rotation of 180° of the milling assembly, while rotating the connecting rod and crank system by about 36°.
  • the panel is carried along on a conveyor belt or similar carrying device of a known type and brought up to the processing area, where its presence is detected by a sensor of a known type not shown in the figure but connected to the support of the milling assembly.
  • the milling group moves up to contact the upper surface of the same, and the tool is rotated.
  • this also actuates the motor 9, which causes the milling group, with the aid of the recirculating roller screw 10, to slide along the guide 7 arranged on the inclined plane 8, and therefore to move forward along with the panel.
  • the tools run along a curve corresponding to the profile to be imparted to the edge, thus performing the milling process.
  • the latter works in a manner similar to the former, by using a sensor to prime the starting motion of the tool, which slides along the guide 7 by moving forward along with the panel while being simultaneously rotated, by the lever 13, in a direction opposite to that of the milling assembly 3, thus achieving a processing effect similar to that performed on the front edge.
  • the flanging machine produced in this manner allows achieving a better precision in following the desired profile while also allowing an optimization of the tool's shifting speed with respect to the panel.
