Definitions

  • the invention refers to a friction device needed in rail motor unit carriages to maintain the drive effect when slopes would cause the drive wheel to slip on the guide rail.
  • Rail motor unit carriages used in interior conveyor systems have difficulties in going up slopes in the guide rail. This problem is currently solved by placing an auxiliary guide rail parallel, above the main guide rail, and furnishing the rail motor unit carriage with at least one auxiliary wheel assembled on swivel arms, so that it is positioned sideways above the drive wheel.
  • the auxiliary guide rail causes the auxiliary wheel to descend and press on the drive wheel, so that the friction between this wheel and the main guide rail increases and the drive wheel does not slip on the main guide rail -which would eliminate the movement of the carriage- but continues its drive operation.
  • the auxiliary wheel is mounted on the central part of a swivel arm with one end mounted on a axis fixed to the carriage chassis. This arm tends to fold on the drive wheel by means of a spring which operates on the opposite end of the aforementioned lever.
  • the auxiliary wheel is mounted on a set of articulated levers which are held in the axis itself of the drive wheel and maintains contact between the auxiliary wheel and the drive wheel by means of a spring operating on the free end of the set of levers.
  • auxiliary wheel or wheels To solve the aforementioned problem, it is planned for the auxiliary wheel or wheels to be mounted completely independent from the drive wheel. They are assembled on one of the ends of the hinged arm connected to the rail motor carriage by means of a transversal axis.
  • the support arm To achieve the necessary pressure of the auxiliary wheel or wheels on the drive wheel on slopes, it is planned for the support arm to have elastic devices in its intermediary part which tend to move the wheel lengthways with respect to the arm, keeping it away from the arm's spin axis.
  • auxiliary wheel can move lengthways towards the rear area of the arm when the auxiliary guide operates on it, thereby maintaining the required pressure on the drive wheel.
  • the main advantage of the invention is that the arm and the auxiliary wheel form a unit which can be separated from the carriage quickly and simply without the need to dismount the drive wheel nor any other component of the carriage, therefore saving a considerable amount of time.
  • the carriage consists of a chassis (1) furnished with a drive wheel (2) which stands on the main rail (3) to cause the latter to go forward.
  • auxiliary wheels (4) stand on the drive wheel (2), mounted on the corresponding swivel arm.
  • the purpose of these auxiliary wheels is to press on the drive wheel when they move towards the lower area by means of an auxiliary rail (3a) parallel to the main rail (3) and located on slopes of the run.
  • the swivel arm consists of two cylindrical parts (5 and 6) mounted telescopically and which tend to stay in the extended position by the action of a helicoidal spring (7).
  • the rear part (5) has two side nipples (5a) which form the spin axis of the arm and which are assembled on supports (8) which are inserted in the chassis (1) through the open round-ended holes (1a); fixing the supports (8) to the chassis by means of bolts (8a).
  • This assembly of the arm means that it can be released from the chassis by simply removing the bolts (8a).
  • the front part (6) of the arm has a fork (6a) on which the axis (4a) of the auxiliary wheel (4) is assembled, and above, a non-rotation guide rail (6b) provided with a round-ended hole (6c) in which a bolt (5b) is loosely placed and fixed to the rear part (5) of the arm.

Claims (7)

  1. Dispositif de friction pour l'actionnement de chariots transporteurs continus, semblable à celui qui est utilisé pour les chariots motorisés suspendus à rail, employés dans le transport continu de pièces et qui sont équipés d'au moins un bras à charnière avec une roue auxiliaire (4) qui entre en contact avec la roue motrice (2) du chariot motorisé suspendu à rail lorsqu'un rail auxiliaire (3a) fait marcher le précédent, et qui est placé parallèlement au rail principal (3) en inclinaisons du parcours, caractérisé par le fait que les roues auxiliaires sont montées sur les extrémités précédentes des bras de longueur variable, équipés de dispositifs élastiques qui tendent à maintenir ces bras en position tendue, et par le fait que ces bras sont giratoires et désaccouplables, et sont montés sur le châssis du chariot motorisé suspendu à rail grâce à un axe giratoire, permettant de retirer tout le dispositif en lâchant cet axe.
  2. Dispositif, selon la revendication précédente, caractérisé par le fait que le bras est composé de deux pièces (5 et 6) dont le montage est télescopique.
  3. Dispositif, selon les revendications précédentes, caractérisé par le fait que les dispositifs élastiques incorporés sur le bras sont composés d'un ressort hélicoïdal (7) situé longitudinalement entre les pièces (5 et 6) qui composent le bras.
  4. Dispositif, selon les revendications précédentes, caractérisé par le fait que l'axe giratoire du bras est composé de deux buses alignées (5a) qui sortent latéralement de la partie postérieure (5).
  5. Dispositif, selon les revendications précédentes, caractérisé par le fait que les buses qui forment l'axe sont montées sur des pièces d'appui (8) introduites dans des orifices ouverts arrondis (1a) définis sur le châssis (1) fixés au moyen de boulons (8a).
  6. Dispositif, selon les revendications précédentes, caractérisé par le fait que la partie antérieure (6) du bras a une fourche frontale (6a) sur laquelle est monté l'axe (4a) de la roue auxiliaire (4).
  7. Dispositif de friction, selon las revendications précédentes, caractérisé par le fait que la partie antérieure (6) du bras est équipé d'un rail supérieur non giratoire (6b) muni d'un orifice arrondi (6c) dans lequel est facilement introduit un boulon (5b) qui est fixé sur la partie postérieure (5) du bras.
