Definitions

  • the present invention patent refers to a machine for the transport and precision positioning of pieces of fabric, tapes and the like.
  • bonnets, fins and other body elements in composite materials in the automobile industry.
  • the head descends, engaging in the vertical guides until the porous fabric is flat in contact with the table. Then the fan sucks and the fabric is glued to the porous fabric of the head.
  • the head rises, always with the fan running, and when it has been separated from the table, it moves horizontally to the position provided on the deposit table, then descending, thus Crazy the web at the intended site. It then inverts the flow, blowing on the fabric (this is not necessary if it is not adherent) and rises leaving it in the mold, after which the fan stops and the cycle is restarted with another fabric.
  • Figures 7, 8 and 9 represent the positioning table, seen in elevation and in plan.
  • Figures 10, 11 and 12 represent the head viewed laterally and with a detail of its structure.
  • Figures 13 and 14 are elevation views of the deposit table according to figures 1 and 2, 3 and 4.
  • the positioning table -1- is a perforated table, the material of which -6- depends on the fabric at hand
  • the fabric is positioned with the required precision, either by a robot with vision, or manually using optical projection of the shape.
  • the table also supports vertical guides -9- that ensure the relative positioning of the head -2- with the required precision.
  • the head -2- represented in figures 10, 11 and 12 consists of a frame, -10- a bell - -11- with fan -12-, in its upper part, supporting a piece of porous fabric -13 - with a ⁇ tre -14- and accessories -15- and -16-. or.
  • the frame -10- presents in plan a normally rectangular shape and of adequate dimensions to the type of work to be carried out. It constitutes the supporting structure of lifting anchors, elements - positioning and guidance, support for the hood and
  • the hood -11- consists of a nozzle supported on the frame and supports on its upper part a fan -12- driven by a variable speed electric motor, adjusted to the application and reversed
  • porous fabric -13- teflon if there is a need to avoid adhesion, is sewn laterally - to two plates that are fixed to the frame -10- and is - equipped with an arrow sufficient to adapt to the

  • the ballast can be simply made up of balls -18- deposited on the fabric or threaded into threads attached to the frame -10-.
  • elements -15-and-16- of adjusting the arrow of the porous fabric and the ballast and heating of the air for blowing the fan towards the porous fabric may be considered.
  • the transmission device -3- is constituted by a porch -19- with a carriage -20- that transports the head -2- from the position table -1- to that of the tank -4- equipped with a - motor for its ascent and descent, another for its displacement, horizontal positioning and position sensors for its detention at the appropriate points.
  • the transmission can be simplified without the car and its horizontal displacement.
  • the transmission is limited to raising and lowering, the positioning table is, in this case, mobile and positions the fabric behind the head, withdrawing when the head has picked up the fabric so that it can be deposited in the table, of deposit that is permanently in a level inferior to the one of displacement of the table of position.
  • the deposit table -4- represented in figures 13 and 14, is formed by two stringers 22 and 22 that support sets of stems or vertical guides 23 and 24, similar to the stems -9- of the positioning table - 1-, in as many positions as necessary.

Abstract

La machine comprend une table de positionnement, une poupée, un dispositif de transmission pour la poupée, une table de dépôt et un tableau de commandes. La table de dépôt possède un revêtement avec des perforations et un impulseur pneumatique inférieur, ainsi que des moyens de centrage pour la poupée, cette dernière ayant la forme d'une cloche avec un ventilateur supérieur et une pièce de tissu poreux, adaptable à la table de positionnement et à la table de dépôt, le dispositif de transmission ayant un mécanisme d'actionnement de la poupée. Application au déplacement et à l'orientation de pièces de matériaux flexibles dans des processus automatisés de fabrication.
