Definitions

  • This invention concerns apparatus for feeding sheet materials particularly, though by no means exclusively, of corrugated board or card as used in the box and carton making industries.
  • stacked sheets are placed on a feed table against a gate which allows only the lowermost sheet to pass therebeneath under the action of a reciprocating vacuum suction cup, feed rollers or a kicker mechanism, to be taken into the nip of take-up rolls.
  • a reciprocating vacuum suction cup, feed rollers or a kicker mechanism to be taken into the nip of take-up rolls.
  • Such feeding arrangements must be controlled with great precision and even then misfeeds are a not uncommon experience.
  • apparatus for feeding sheet material comprising a feed table having a gate and upon which the sheets may be stacked against the gate which allows only the lowermost sheet to pass therebeneath, a bed of rollers within the surface of the table which may be rotatably driven to advance the lowermost sheet beneath the gate into the nip of take-up rolls and means to allow the rollers to free-wheel once the lowermost sheet is being advanced by said take-up rolls.
  • the rollers may be fitted with sprag clutches and may advance the sheet being fed at a slower speed than that of the take-up rolls.
  • Vacuum suction may be applied from beneath the rollers to pull the lowermost sheet downwardly thereagainst.
  • the rollers may be spaced such that the lowermost sheet can drape to give substantial area contact between the sheet and the rollers.
  • the apparatus comprises a feed table 10 upon which a stack of sheets S may be placed against a gate 11 beneath which only the lowermost sheet in the stack may pass.
  • rollers are mounted within a chamber 15 to which vacuum suction is applied to pull the lowermost sheet downwardly thereagainst.
  • the spacing between the rollers 14 allows the sheet to drape between them to enhance the area of contact.
  • rollers advance the lowermost sheet by being rotatably driven as indicated by the arrows X at a speed less than the speed of the take-up rolls 12. Once the sheet is advanced by the rolls 12 the rollers 14 free-wheel, the rollers 14 having sprag clutches between their inner peripheries and their drive shafts 16.
  • rollers 14 are rotatably interconnected by drive belts 17 and one roller 14 is driven by a belt 18 itself driven from a toothed belt 19 reciprocated by an arm 20 operating in time with line speed (typically that previously used for a kicker mechanism, facilitating easy retro-fitting).
  • line speed typically that previously used for a kicker mechanism, facilitating easy retro-fitting.
  • the rollers 14 are not driven in reverse direction since they are then in their freewheeling mode.
  • the rollers 14 may be driven intermittently or continuously by an electric motor, though this is not preferred since, in the case of a continuous drive, there will be some slippage between the rearward rollers and the next sheet to be fed until the previous sheet has cleared the gate 11.

Claims (9)

  1. Dispositif d'alimentation en matériau sous forme de feuilles comprenant un plateau d'alimentation (10) doté d'un portillon (11) et sur lequel les feuilles (5) sont empilées contre le portillon qui ne permet qu'à la feuille la plus basse de passer sous lui, un banc (13) de rouleaux (14) dans la surface du plateau, caractérisé en ce que ces rouleaux sont entraínés mobiles en rotation de façon à faire avancer la feuille la plus basse sous le portillon dans la zone de pincement de cylindres récepteurs (12) et en ce qu'il comprend des moyens destinés à permettre aux rouleaux de tourner en roue libre une fois que la feuille la plus basse est avancée par lesdits cylindres récepteurs.
  2. Dispositif selon la revendication 1, dans lequel les rouleaux sont équipés d'embrayages à roue libre et font avancer la feuille qui est amenée à une vitesse plus lente que celle des cylindres récepteurs.
  3. Dispositif selon la revendication 1 ou la revendication 2, dans lequel une aspiration est appliquée depuis le dessous des rouleaux de façon à tirer vers le bas contre eux la feuille la plus basse.
  4. Dispositif selon l'une quelconque des revendications 1 à 3, dans lequel les rouleaux sont espacés de sorte que la feuille la plus basse peut s'étendre sous forme de drapé afin de créer une superficie de contact sensible entre la feuille et les rouleaux.
  5. Dispositif selon l'une quelconque des revendications précédentes, dans lequel les rouleaux sont interconnectés de façon mobile en rotation par des courroies d'entraínement (17), et l'un d'entre eux est entraíné par une autre courroie d'entraínement (19) déplacée avec un mouvement de va-et-vient par un bras (20) fonctionnant en cadence avec la vitesse de la ligne.
  6. Dispositif selon la revendication 5, dans lequel ladite autre courroie d'entraínement est dentée.
  7. Dispositif selon l'une quelconque des revendications 1 à 4, dans lequel les rouleaux sont entraínés par un moteur électrique.
  8. Dispositif selon la revendication 7, dans lequel les rouleaux sont entraínés de façon intermittente.
  9. Dispositif selon la revendication 7, dans lequel les rouleaux sont entraínés en continu.
