Definitions

  • the invention relates to a device for depositing successive curved workpieces after the last processing step carried out in a press tool for their further transport in receiving devices according to the preamble of claim 1, being published by a state of the art according to the article "Manufacturing medium-sized body parts on a large press” in: Princeton und strig, 111 (1978) 3, page 215.
  • the workpiece sequence takes place at the end of the processing in the press or after an intermediate stage via slides and conveyor belts.
  • the workpieces can be derived in open-plan platforms or placed manually in stacking racks. Two stacking racks are provided for each discharge point, and there is no interruption during the stacking process, since the second stacking rack can be filled while changing from a full stacking rack to an empty one.
  • Surface damage to the body elements and, in particular, damage which - viewed in the backlight - can be recognized as a shadow on the surface of the finished part after the application painting are unavoidable.
  • DE-A-19 43 125 describes a device for erecting, stacking and conveying flat individual parts.
  • the individual parts or also stacked individual parts are fed to a turnstile by a conveyor belt via a slide plate and pivoted through this into a high position. After the transfer of the individual parts or stacks to another conveyor belt, the individual parts or stacks are strung together and temporarily stored.
  • the packages compiled in this way are picked up by means of a horizontally and vertically movable gripper device and placed on a storage disk belt. Furthermore, it is provided that the packages are alternately placed on two transversely projecting storage belts in the extension of the conveyor belt or by means of tandem-like transfer grippers.
  • a translation gripper has been described in US-A-3 178 041.
  • the flat individual parts which are brought into the movement range of the transfer gripper on a roller conveyor are optionally gripped by one of two gripping devices and placed in one of two transport frames assigned to the respective gripping device.
  • the picking up of the individual parts from the roller conveyor and placing them in the transport frame can, as in the case of the above-mentioned device, take place in such a way that only one transport frame is initially loaded or that alternately the storage of an individual part by a gripping device in one transport frame and the subsequent item is carried out by the other gripper device in the second transport frame.
  • the individual parts touch in individual areas and also over a large area, so that influences on the surfaces and also damage in edge and surface areas cannot be avoided.
  • These parts such as doors, hoods and the like car body parts, should be available after the last processing operation in a press for further processing steps or directly for surface treatments.
  • the z. B. corresponds to the treatment situation in the surface preservation and embellishment.
  • the workpieces can be fed directly to the cleaning, preserving and painting baths without having to turn them over again.
  • a cross slide part is provided which can be controlled to deposit the workpieces in time with the press, with the advantages of a continuous automatic depositing.
  • the surface treatment is not carried out in the press area.
  • transport frames are provided for hanging transport which, like the chain conveyors, are advantageously displaceable step by step parallel to the workpiece dispensing from the press.
  • the storage in the transport position can be done by a horizontal as well as a vertical movement.
  • the output area of the workpieces 17, which are led out of the work area 2 of the press 1, is formed by a drive 5 for a transfer device 6.
  • the workpieces removed from the press arrive at a feed conveyor 8, which is formed from a roller conveyor with rollers driven by the motor 22 or corresponding conveyor tracks, via a finished part conveyor 7, which is driven by means of a motor-gear unit 21 or by the ram drive of the press and the workpieces transported into the swivel area of the swivel device 10.
  • the swiveling device essentially consists of a frame, in the upper area of which swivel arms 11 are pivotably or rotatably mounted about a pivot point for erecting the incoming workpieces.
  • the swivel arms are driven clockwise in the observer's view via the drive motor 23, which is controlled by a signal.
  • the drive motor 23 which is controlled by a signal.
  • passages are left free for the movement of the swivel arms.
  • the workpieces pivoted into the vertical are removed from the swivel arms by gripping elements 12, for example by suction elements working with controlled negative pressure.
  • the gripping elements are located on a carriage which can be moved perpendicularly to the previous conveying direction by a motor-gear unit 24 and which is essentially formed from a cross slide 16 and, if appropriate, components to be described later and can be designed differently according to its different tasks.
  • the cross slide is slidably mounted on a cross member 15, which is part of a portal 9, which consists of stands 13 and 14 upper chords.
  • the queue slide carries suction elements at its two end areas, so that when the cross slide stops moving, one end area with a workpiece is located in a storage area, while the other end area is in the area of the pivoting device for gripping a subsequent workpiece. After it has been grasped and the workpiece conveyed into the storage area has been deposited, this is guided into a second storage area as a result of the opposite movement of the cross slide and is deposited here, while another workpiece is gripped by the gripping elements of the end region of the cross slide mentioned above.
  • the storage areas are located on both sides and in parallel alignment to the first workpiece conveying direction and are each formed from a chain conveyor 31, which has chain links 32, not shown but known, with chain hangers 32 and conveys the detected workpieces via conveyor and deflection rollers 33, e.g. to the first surface treatment station or by containers 18 placed on a ramp 19 and above them running container conveyors 20 in the manner of transport frames with receiving strips 26 for spaced storage of the workpieces.
  • the chain conveyor is driven step by step via the motor 34, and the container conveyor is driven step by step via the drive unit 25.
  • the containers 18 are already at the height of the workpiece 17 pivoted into the vertical by the swivel device 10. This is gripped by the gripping elements 12 of the cross slide 16 for movement in the direction perpendicular to the plane of the drawing. 1 shows the curvature of the vertically arranged workpieces on the cross slide and in the container which is kept open on the side.
  • Position 3 refers to gripper rails for transporting the workpieces between the press stages and, if necessary, for dispensing the workpieces.
  • Fig. 3 shows the vertical arrangement of two workpieces 17, one of which is for storage in the container 18, another is still in the pivoting device 10.
  • Fig. 4 refers to a further embodiment shown in this and in Figs. 5 and 6 with floor-level container conveyors 20 and for inserting the workpieces from above into the container vertically displaceable cross slide 16.
  • the workpieces 17 are in one position pivoted above the container 18 and guided.
  • the workpieces 17 are conveyed in the direction of travel, this expression relating to the installation position on the vehicle.
  • the workpieces are inserted into the container 18 from above.
  • the workpieces stored in these indicate the curvature and thus their storage position.
  • the cross slide 16 is motor-driven in the longitudinal extent of the cross member 15.
  • a left and a right lowering spar 29, 30 are assigned to the end regions of the cross slide, and their height can be adjusted in height via the drive unit shown in FIG. 4 for inserting the workpieces into the containers from above.
  • the gripping elements 12 on the cross slide 16 or on the lowering bars 29, 30 grip the workpieces 17 on the swiveling device 10 from the side, so that there is no obstruction by the gripping and moving elements when they are put down.
  • FIG. 7 shows a turner 3.5 that can be rotated by the motor 36 for swapping the workpieces 17 on the side before being accessed by the pivoting arms 11.
