Definitions

  • the invention relates to a clipboard for essentially large-area workpieces in the area of an empty stage in the workpiece passage of a transfer press caused by a transport device with at least two storage templates per workpiece of different shape with a support adapted to the lower surface of the workpiece in the support area.
  • the length of the unsetting movement of the workpieces is set via the drive of the transport device.
  • the distance between e.g. the third stage and the fourth stage in a multi-column press is larger due to the empty stage between two press columns, e.g. twice as large as the distance between the work stages which are acted upon by a single plunger and adjacent.
  • a deposit is to be provided, in which workpieces can be removed from the transport device in the meantime and can be detected again.
  • the object of the invention is to provide a clipboard in the area of empty stages in presses of the types specified above, which does not have the disadvantages mentioned, can also be used in presses with a lock case and can be moved in height to the piston stop in order to achieve the desired position of the storage templates.
  • Claim 2 contains an advantageous development of the inventive concept.
  • the further claims contain four preferred embodiments of the invention.
  • Advantages of the invention result from the fact that starting, lifting and lowering of the storage templates is fully automated when changing tools, and there is no need for replacement and readjustment work.
  • the control effort is reduced to a positioning of the storage templates to be lifted and the lifting process against the stop.
  • the clipboard is located between two stands 1 of a press.
  • the transport direction of the workpieces in Figures 1, 3 and 6 is perpendicular to the plane of the drawing; 2, 4 and 5, the transport direction, which characterizes the direction of the workpiece passage, is indicated by the arrow 2.
  • the over the transport device, of which the gripper-carrying rails 3 are shown, possibly into the press, through the press and possibly out of this workpieces 4 are to be put down in the area between the two stands 1, which face each other transversely to the transport direction 2.
  • support templates 6 are used for support, the support surfaces 7 of which, which can also be of divided design, correspond to the shape in the support area of the underside of the workpiece 4 to be supported.
  • the storage templates can run in their longitudinal extent in the transport direction 2, FIGS. 1 to 4, and also transversely to the transport direction 2, FIGS. 5 and 6.
  • the embodiments show favorable positions of the storage templates 6.
  • the invention is not tied to the indicated lock case 8, its presence and its position.
  • the storage templates 6 are adjustable in height and divided into two groups for supporting the workpieces 4 at a distance from one another.
  • 1 to 4 show storage templates 6, which have pivot bearings 11 on their underside in the end regions 9 (FIGS. 2 and 4), of which a pivot bearing is movable in a horizontally extending elongated hole 12.
  • a bearing block 13 is articulated, which in guide rails 14 in slide guides 16 one in 1 and 2 frame-mounted bearing rail 17 is guided.
  • the bearing rail 17 can be made in one piece for each bearing side 18, 19 and extends essentially over the entire width / length of the support area / the empty step.
  • the storage sides 18, 19 each mark the left and right support sides of the storage templates 6 and their lifting means in FIGS. 2, 4 and 6 or the rear and front support sides in FIGS. 1, 3 and 5. Positions 18 , 19 are only shown in FIG. 2, since the same means are used for both support sides within the respective embodiment.
  • On each bearing block 13 there is also a counter bearing surface 21 which interacts with the piston 22 of a working cylinder-piston unit 23 or a corresponding actuating means for lifting. Each working cylinder-piston unit 23, hereinafter referred to as lifting means, is fastened in FIGS.
  • a lifting device 23 is assigned to each end region 9 of each group of storage templates 6.
  • Motor 28, spindles 27 and slide rails 26 are fastened to the bearing rail 17 via bearing brackets 29.
  • a toothed belt drive composed of toothed belts 31 and toothed wheels 32, 33 is used for synchronous running of the slides 24 on the opposite side of the storage templates 6, or two motors 28, each acting on a spindle 27, are required.
  • the carriages 24 can only be moved if query means assigned to the bearing blocks 13, e.g. Proximity switch 34, the lowered position of all or the position of the two last storage templates 6 has been determined.
  • query means assigned to the bearing blocks 13, e.g. Proximity switch 34 the lowered position of all or the position of the two last storage templates 6 has been determined.
  • the lifting means 23 are adjusted via the motor-spindle-slide drive, and each piston 22 of the lifting means 23 comes under the counter surface 21 of the storage template 6 to be lifted.
  • the height of the counter surface 21 on the storage templates 6 can be different, so that the lifting means in different Empty paths are to be traversed until they come into contact with the counter surfaces.
  • the height of the bearing surface 7 can be adjusted via the overall height of the storage templates 6 and the path of the piston 22 of the lifting means 23 which is still to be moved.
  • FIGS. 1 and 2 show the same components as FIGS. 1 and 2 with the difference that the lifting means 23 are arranged fixed to the frame in all (differently shaped) workpieces common support area.
  • Each group of storage templates 6 can be moved horizontally via a spindle drive in order to place the pair of storage templates 6 to be lifted above the lifting means 23.
  • Each group of storage templates 6 is arranged on a common, movable carriage 36, each storage template 6 being mounted for vertical movement in the manner described above.
  • a spindle 30 driven by the motor 28, which is supported in the center in a bearing block 37 serves the opposite movement.
  • Storage templates 6 and their drive and bearing means are supported on the frame side by means of pedestals 38.
  • FIG. 5 and 6 a further simplified embodiment of an intermediate storage is shown, which is supported on bearing rails 39 and support plates 41 on e.g. the lock box 8 is attached.
  • slide guides 42 are provided for the storage templates 6 to be lifted.
  • a counter-surface 21 is arranged on the underside of each storage template 6 with respect to each end region 9.
  • a frame construction consisting of two side supports 43, which are connected to one another via two guide rods 44, is arranged below the storage templates 6. The frame can be lifted and lowered (vertically) by one or more lifting devices 47 fixed to the frame in the area of the side supports 43 in the region of the side supports 43.
  • a spindle 48 which can be driven by the motor 28 is mounted centrally and extending in the longitudinal extent of the intermediate storage.
  • an intermediate member 49 is arranged which can be moved in the longitudinal direction of the frame construction and which interacts with the counter surfaces 21 on the selected storage template 6 when the lifting means 47 is actuated in the manner of lifting the storage template 6.
  • the intermediate member 49 is additionally shown rotated by 90 ° in FIG. 5.
  • Motor 28 and angle encoder 50 can be attached to the overall frame structure to be lifted in accordance with FIGS. 5 and 6 and thus be lifted when lifting a pair of storage templates 6.
  • Motor 28 and angle encoder 50 can, as shown in more detail in FIGS. 5 and 6, be mounted fixed to the frame.
  • sliding blocks 51 are to be provided in the intermediate members 49 as nuts for the spindle 48.
