Definitions

  • the invention relates to an assembly line with at least one rotary conveyor, which transports workpieces, and at least one processing station, which has a plurality of processing positions arranged one behind the other in the conveying direction.
  • workpiece carriers which are usually designed as pallets, are transported by a conveyor. There are workpieces on the workpiece carriers that are processed at the processing stations, for example by adding components.
  • the invention has for its object to provide an assembly line in which the changing times of the workpieces are shortened, so that the degree of utilization of the processing machines is improved.
  • the workpiece carriers are then transferred to the processing station to an intermittently operating auxiliary conveyor which transports the workpiece carriers from one processing position to the next within the processing station.
  • a controlled holding element is provided at each machining position, which acts on the workpiece carrier after completion of a feed step of the auxiliary conveyor and thereby positions the workpiece carrier in the correct position.
  • an intermittently operating auxiliary conveyor is provided which is operated independently of the circulating conveyor.
  • the circulating conveyor is usually a continuous conveyor.
  • the auxiliary conveyor effects the transfer of the workpiece Carrier within a processing station from one processing position to the next.
  • a holding element is provided which is fixed at the machining position and which not only holds the workpiece holder in place, but also positions (indexes) it in the correct position in order to bring the workpiece into a defined position required for machining.
  • the auxiliary conveyor preferably extends from a transfer position over at least two processing positions, so that it takes over a workpiece carrier at the transfer position and moves at least two further workpiece carriers away from processing positions.
  • the auxiliary conveyor has a bar which extends over at least two machining positions and is driven in the longitudinal direction and which has at least one controlled driving element which engages on the workpiece carrier.
  • the driving element brings about an exact fixation of the workpiece carrier on the auxiliary conveyor. It is controlled in a suitable timing with the holding member in such a way that the driving member engages during the feed step, while after the workpiece carrier has been transferred to the machining position, the driving member disengages and engages the holding member.
  • the workpiece carrier is thus, so to speak, transferred directly from the driving element of the auxiliary conveyor to the fixed holding element of the processing position.
  • the workpiece carriers can have rollers which engage prism rails in the processing station in order to carry the workpiece carrier. This ensures a low-friction and high-precision carrying function.
  • Fig. 1 is a plan view of a. Assembly line
  • FIG. 4 shows a schematic side view of a processing station with the time control of the holding members and receiving members
  • Fig. 5 is a schematic side view of another embodiment of a processing station.
  • FIG. 2 shows a processing station BS with a transfer position UP and four processing positions BP1-BP4.
  • a circulation conveyor 12 made of two parallel conveyor belts 13, 14 runs through the processing station BS and is guided around deflection and drive rollers 15.
  • the horizontal bar 19 is intermittently reciprocated in the longitudinal direction by a motor 20.
  • FIG. 3 shows a vertical section through the transfer position UP or one of the processing positions.
  • the prism rails 17, 18 are fastened on vertical stands 22 and each have a V-shaped (prismatic) edge 23.
  • rollers 24 with a vertical axis are rotatably mounted on the top of the workpiece carrier WT. These rollers each have a V-groove into which the edge 23 of the prism rail penetrates. In this way, the workpiece carrier is centered in the horizontal plane as well as in the vertical direction by the prism rails.
  • the circulation conveyor is fastened between the stands 22.
  • the circulation conveyor has two parallel profile beams 25 which carry the endless belts and deflection rollers.
  • the prism rails 17, 18 are of such a height that the workpiece carrier WT lifts slightly from the conveyor belts 13, 14 of the circulating conveyor 12, so that the circulating conveyor is no longer effective in the further course of the processing station BS.
  • Driving elements 26 are fastened to this beam, which can each penetrate from below with a driving bolt 27 into a fitting hole 28 of the workpiece carrier WT and thereby additionally position the workpiece carrier in the longitudinal direction.
  • the driving pin 27 is connected via a rod 29 to a piston 30 which is movable in a compressed air cylinder 31. By controlling the compressed air cylinder, the driving element 26 can be actuated by moving the driving pin 27 into the workpiece carrier WT.
  • the fitting hole 28 is at the front right end of the workpiece carrier WT, while the fitting hole 37 is at the rear left end.
  • the pass holes are on a diagonal. Accordingly, the driving member 26 and the holding member 35 are offset from one another in the longitudinal direction of the conveyor.
  • Fig. 4 shows a. the bar 19 shortly before the driving elements 26 engage in the fitting holes 28 of the workpiece carriers WT.
  • those places are marked by arrows at which there are stationary holding members 35 and along the line 51 those places are marked by arrows at which there are entrainment members 26 of the auxiliary conveyor 16.
  • the motor 20 of the auxiliary conveyor 16 drives a rack 53 of the bar 19 via a gear wheel 52, as a result of which the bar 19 is moved back and forth in its longitudinal direction.
  • the stop 21 is raised so that it blocks the workpiece carrier WT in the transfer position UP.
  • the first entrainment member 26 is in the transfer position UP in this phase. All other entrainment members 26 are in the waiting position, while the stationary holding members 35 engage in the workpiece carrier WT.
  • the stop 21 is lowered from FIG. 4, the holding members 35 have released the workpiece carriers WT and the entrainment members 26 engage the workpiece carriers.
  • the movement of the bar 19 to the right begins.
  • the rollers 24 engage on the prism rails 17, 18, which lift the workpiece carrier from the conveyor belts 13, 14 and support it during further transport.
  • the end of this movement is in section c. shown by Fig. 4.
  • the movement of the bar 19 is sinusoidal, that is to say initially at a very low speed, which then increases and finally decreases again to zero. This keeps the maximum accelerations that occur.
  • the workpiece carriers are carried exclusively by the drive elements 26.
  • section d. 4 the workpiece carriers WT have reached the respective target position.
  • the stop 21 is raised so that the next workpiece carrier strikes it.
  • the driving elements 26 of the beam 19 are lowered and at the same time the holding elements 35 are raised. In this. Situation, workpiece machining can take place immediately.
  • the bar 19 can still during the workpiece machining in the starting position according to section e. retract from Fig. 4.
  • the processing positions BP are at mutual distances, so that the workpiece carriers have to be separated so that they take up corresponding distances in the processing station.
  • 5 shows another using a further example another possibility of separating the workpiece carriers WT.
  • the bar 19 is in turn linearly driven by a gear 52 which engages in a toothing 53 of the bar.
  • the bar 19 is connected via a gear 55 to a further bar 56, which is thereby driven at half the speed of the bar 19.
  • the gear 55 has a fixed toothing 57 which is in engagement with a gear wheel 58 mounted on the bar 56. This gear is also in engagement with a rack 59 which is fixedly connected to the beam 19.
  • the beam 56 has a controlled entrainment member 26a which engages the workpiece carrier WT in the transfer position UP and then pulls it into the first processing position BP1. This stroke is called the feed stroke. It is half the size of the subsequent working strokes.
  • a further bar 60 is provided, which is fixed to the bar 56 via a rod 61.
  • This bar 60 has a driving element 26b. It causes an ejection stroke of the workpiece carriers from the last machining position BP4 to the discharge position AP, which is half the size of a working stroke. In this way, the workpiece carriers are placed closer together again at the end of delivery.

Abstract

L'invention concerne une chaîne de montage comprenant un transporteur continu (12) sur lequel sont transportés des supports de pièce (WT). Lesdits supports de pièce (WT) sont isolés au niveau d'un poste d'usinage comportant plusieurs positions d'usinage (BP1-BP4). Le poste d'usinage comprend un transporteur auxiliaire (16) qui saisit les supports de pièce à l'aide d'organes d'accrochage (26) afin de transporter lesdits supports d'une position d'usinage à la suivante. Lors de cette opération, le transporteur continu (12) n'est pas employé. Lorsque la position d'usinage est atteinte, l'organe d'accrochage (26) libère le support de pièce (WT), puis un organe de retenue (35) fixe saisit ledit support et le maintient en place pendant l'usinage de la pièce. Lors de cette opération d'usinage, le transporteur auxiliaire (16) peut déjà revenir à sa position de départ. Le transfert des supports de pièce d'une position d'usinage à la suivante est ainsi raccourci.
