Definitions

  • the invention relates to a device for storing of workpieces after the last in a pressing M ool performed processing step for their further transport, in particular for non-contact deposition of curved workpieces, such as body components in receiving devices, with a device for withdrawing the work pieces from the press.
  • the workpieces can thus be fed to further processing and / or treatment stages, for example surface treatment for the purpose of corrosion protection, surface beautification and the like. serve.
  • the size of the parts has so far been used e.g. 4 people employed. This enabled uninterrupted stacking and the parts were placed undamaged on their surface; however, the labor costs incurred were high.
  • the workpiece sequence takes place at the end of processing in the press or after an intermediate stage using 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 a full stacking rack for an empty one. Surface damage to the body elements, and in particular such, cannot be avoided Damage that - when viewed against the light - can be seen as a shadow on the surface of the finished part after the application has been painted.
  • coated sheets are passed through a drying oven by means of a chain conveyor having a holding finger to avoid surface damage and are deposited from the vertical position into the horizontal position on a conveyor belt and from there by deflecting an intermediate deflecting conveyor belt optionally into one of two containers placed on movable pedestals.
  • the last phase of the deposit takes place under the force of gravity and is only controlled by wall parts of the container after the board to be put down has been placed with an edge on the last set board.
  • the US-PS 2 685 359 shows a turning device for flat workpieces within a conveyor line with turning spokes, which are arranged parallel to a part of the conveyor line forming conveyor belts and are guided through gaps between them when the turner rotates.
  • These parts such as doors, hoods and the like car body parts, should be available for further processing steps in a press after the last processing operation or directly for surface treatments.
  • the object is achieved by means of a device which pivots the workpieces from the production position into a vertical (transport) position, which, if appropriate with the interposition of a finished part conveyor for bridging the distance, is guided into the effective range of the workpiece removal device, by a cross slide part for taking over workpieces from the pivoting device, which grips the workpieces by means of gripping elements and leads essentially perpendicular to the conveying direction of the finished part conveyor out of the swiveling area into storage areas, and by means of transport frames arranged interchangeably in the storage areas, with the use of rescue conveyors, corresponding suspensions for vertical storage of the workpieces.
  • the workpieces are advantageously brought into a transport position directly after the last processing stage, which e.g. the treatment layer serves for surface preservation and beautification.
  • 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 is controllable 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, according to claim 3, are advantageously displaceable step by step parallel to the workpiece dispensing from the press.
  • the output area of the work pieces 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 motor 22 or corresponding conveyor belts, via a finished part conveyor 7, which is driven by means of a motor-gear unit 21 or by ram drive of the press and the workpieces transported into the swivel range 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 necessary, 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 uprights 13 and upper chords 14.
  • the cross 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 as a result of the opposite movement of the cross slide into a second storage area 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 not shown but known chain links 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 19 placed on a ramp 19 and above them running container conveyors 20 in the manner of transport frames with pick-up 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 level 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.
  • F ig. 2 shows, inter alia, the storage devices extending parallel on both sides to the conveyors 7 and 8, such as containers 18 and chain conveyors 31 for storing, receiving, hanging and the like.
  • the workpieces are oriented in such a way as to come from the press tool that they are transported with the door uprights upwards, i.e. in the position of use, after being erected.
  • 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 containers Conveyors 20 and for inserting the workpieces from above into the container cross slide 16.
  • the workpieces 17 are pivoted into a position above the container 18 and quenched.
  • 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 being put down.
  • FIG. 7 shows a turner 35 that can be rotated by the motor 36 in order to swap the workpieces 17 lying on the side before being accessed by the pivoting arms 11.
