Definitions

  • the invention relates to a flexible transfer device for presses, in particular large presses for processing sheet metal parts, with the features of the preamble of patent claim 1.
  • presses preferably in press lines (DE 27 47 237 A1), which are equipped with transfer or feeder systems for entering and removing and for transporting the sheet metal parts between the presses.
  • press lines DE 27 47 237 A1
  • transfer or feeder systems for entering and removing and for transporting the sheet metal parts between the presses.
  • the last or further presses of this press line can be equipped with several tool sets and an additional transfer device when not in use as a line machine and can be used as a separate transfer press for processing smaller sheet metal parts in several work stages.
  • transfer devices are already known, in which four separate drive units are arranged in the tool room of the press for easier adaptability to the respective sheet metal range, on which support rails provided with gripper elements, suction cups or the like. Are held movably in several axes by means of separate drive motors.
  • a known three-dimensional drive unit for input and removal devices on presses and transport devices between presses, in particular for transfer devices in presses (DE-A-38 02 481), in which a controllable motor is provided for each direction of movement, contains a housing in which a slide for Generation of a first axis of movement is slidably mounted in guide rails.
  • a further slide for generating a second movement axis is mounted on or on this slide, on which in turn a mounting rail is mounted so as to be displaceable in or against the parts transport direction.
  • the parts are always transported in the direction of the longitudinal axis of the mounting rails.
  • the invention has for its object to provide a flexible transfer device for presses that when using the press for processing large sheet metal parts in a press line for feeding or removing the sheet metal parts in the direction of the longitudinal axis of the press line and if necessary when using the press as a transfer press for processing smaller sheet metal parts can be used in several stages for transporting the sheet metal parts between the individual stages transversely to the longitudinal axis of the press line. Furthermore, combinations of the two types of use should be simple, z. B. by appropriate programming of the control for the drives.
  • the gripper or suction bars 21 or the suction bars 26 are turned on manually or automatically provided support supports 25, which are arranged on the movable sliding tables 22, deposited.
  • the secondary beams 16 are moved into a "parking position" (Fig. 4) to the tool room for special needs, such. B. Set up to make it freely accessible.
  • the lifting carriages 5 are additionally guided on two parallel guide columns 6 each.
  • a carrier 7 with parallel guides 8 for the closing movement (y-axis) is fastened on each lifting slide 5, on which the locking slide 9 is guided.
  • the drive for this is a servo drive 10, which is also provided with a connecting gear 11, preferably a toothed belt gear, for synchronously driving a second closing slide 9 belonging to the same secondary beam 16.
  • drive shafts 12 are also used here for transmitting a torque with simultaneous axial displaceability of the bearing for adaptation to the stroke movement (z-axis). So that a deflection gear 13, z. B. a bevel gear can be driven to move the locking slide.
  • a toothed belt transmission is used to double the stroke of the guide bracket 14, in order to achieve the greatest possible transport stroke in the longitudinal axis of the press line, particularly when space is restricted.
  • the entire drives for the closing and lifting movement (y-, z-axis) are each carried by a frame 23.
  • the frames 23 are fixed accordingly on the sliding table.
  • the design of the secondary beams 16 with the servo drives 20 integrated therein for the transport of parts in the x-axis is identical to the first exemplary embodiment.
  • the outermost position in the y-axis can serve as the parking position in order to create a corresponding free space for setting up tools. It is also possible to move the entire transfer device with the sliding table 22 out of the tool space of the press and to carry out a motion simulation outside the press.
  • the primary beams 17 contain gripper elements, which are arranged on gripper slides 24 and can be displaced thereon transversely to the longitudinal axis of the press line. While the primary bar 17 executes a transport stroke in accordance with the tool center distance, the movement of the gripper slides is superimposed on the primary bar movement. The gripper slide retracted in the transport direction executes a superimposed movement that runs counter to the transport movement. In the same way, the last gripper slide extended in the transport direction also executes a movement opposite to the transport movement.
  • the distance between the blank transfer station and the first tool level and the distance between the last tool level and the workpiece transfer station is only a fraction of the tool center distance.
  • optimal use of the tool clamping surface is possible with tools designed at the same time, in particular if the narrow bars 16 of the press prevent the secondary beams 16 from protruding.
  • the modular expansion of the closing slide 9 with a guide bracket 14 driven by a doubling of the stroke, according to the exemplary embodiments described above, is not necessary.
  • the secondary beam 16 can then be articulated directly on the closing slide 9.
  • the use of the separate guide block 14 mounted on the locking slide 9 is also advantageous if an overload protection device in the form of a fluid-loaded cylinder, which is arranged between the locking slide 9 and the guide block 14 and is not shown in the exemplary embodiment, is used in order to avoid a program control independently of the program control Accident to be able to open the grippers quickly.
  • an overload protection device in the form of a fluid-loaded cylinder, which is arranged between the locking slide 9 and the guide block 14 and is not shown in the exemplary embodiment, is used in order to avoid a program control independently of the program control Accident to be able to open the grippers quickly.
