Definitions

  • the invented device applied on the painting machines of the electronic boards of new production or as an accessory onto the already in work machines, permits to remove in continuous and automatic way the paint that, during the painting phases of the electronic boards, settles onto the lateral walls acting to protect the mechanical parts which move the electronic boards wherein the necessary painting work is being implementing. This permits to have cleaning the lateral walls having not to replace said lateral walls in very short times having to stop the painting work.
  • the invented device to be applied on the painting machines of the electronic boards of new production or as an accessory onto the already in work machines, consists of a metallic boxing frame having an inside seat wherein is housed in under position a new paper roll mounted onto an idle roller and in upper position, separated by a V-shaped body, the roll collecting the paper dirty of paint mounted onto a motorized roller.
  • Said V-shaped body shields the clean paper roll and further presses onto the paper turned from the roll so to keep constant the pressure of the paper in unrolling and to permit the control, by a photocell, of when the new paper roll is ended.
  • the new paper roll ended this is stated to the PLC so to proceed at the changing of the same.
  • the invented device is connected to a PLC of the machine that states, by the indications of the operator, every how many steps of spraying rewind the paper and how much rewind.
  • the motorized roller is unlocked and is removed to eliminate the paper dirty of paint, then a new roll is inserted and, placed again in position the motorized roller, the painting machine is started again.
  • Figure 1 is exploded view of the invented device to point out the different parts that, mounted, permit the working of the same.
  • Figure 2 is lateral view to point out the paper roll and the roller for collecting the paper dirty of paint.
  • Figure 3 is perspective view form a side to point out the fixed motorized roller.
  • Figure 4 is view of the boxing frame from the side opposite to the mounted parts.
  • Figure 5 is section view of the device with the motorized roller not mounted.
  • Figure 6 is section view with the motorized roller inserted and blocked in position.
  • Figure 7 is cutaway view of part of the painting machine into which the invented device is applied.
  • the invented device to be mounted into the painting machines of new production and also as an accessory, for those already in production, consists of a metallic boxing frame 1 having an inside seat 1 A delimited by back 1 B front 1C and side 1 D and 1 E walls.
  • seat 1A In the seat 1A is housed a new paper roll 2 then the ending part 2A of the paper is rolled out making it passes before onto the idler rubber 9 then onto the fixed roller 12 and finally onto the outside part of the support part 3 (see figure 2)
  • Upper to the new paper roll 2, always inside the seat 1 A is housed the support body 3 with V-shaped walls 3A and 3B those form an angle less than 90°, with this support body 3 supports with their attachment means 3C at the upper border of the back wall 1 B of the boxing frame 1.
  • the ending part 2A of the new paper roll is foldable to V and insertable in eyelet 4C of the tubular winding 4.
  • the way of the tubular winding 4 must be such that the driving grooves 4B are returned to the fixed motor cone 5 placed laterally of the wall 1 E of the boxing frame 1.
  • the same tubular winding 4 is was inserted before in the fixed motor cone 5, making coincide the driving grooves 4B with the driving pins, and then into the mobile cone 6 placed laterally of the wall 1 D and in backward position.
  • the operator acts onto the knob 7 till that the shutter 8 snaps down blocking the tubular winding 4 and kept it in blocking position. Ending these mounting steps, the invented device is ready to work and to act the cleaning of the painting residuals.
  • the paper that passes pressed to the support body 3 against the idle rubber roller 9, determines the rotation of the same idle rubber roller 9 and of the perforated disk 11 blocked onto it.
  • the photocell 10 detects the rotation of the perforated disk 11 and reports to the PLC the correct winding of the paper during the working of the device.
  • the stop of the idle rubber roller 9 is determined and the PLC reports the situation to the operator.

Abstract

Le dispositif est constitué d'un cadre de boxe métallique (1) ayant un siège intérieur (1A) dans lequel le nouveau rouleau de papier (2) est logé avec la partie terminale (2A) du papier insérée d'abord sur un rouleau en caoutchouc au repos (9), puis sur un rouleau fixe (12) et à l'extrémité sur la partie extérieure du corps de support (3). Supérieur au nouveau rouleau de papier (2), toujours à l'intérieur du siège (1A), un corps de support (3) est logé avec des moyens de fixation (3C) sur le cadre de boxe (1). Une fois que le corps de support (3) est monté et que la partie terminale (2A) du nouveau papier est insérée dans l'œillet (4C) d'un enroulement tubulaire (4), ledit enroulement tubulaire (4) est inséré d'abord dans le cône de moteur fixe (5) puis dans le cône mobile (6). À ce stade, l'appareil est apte à fonctionner et à effectuer le nettoyage des résidus de peinture.
