Definitions

  • the invention relates to a transfer press or press line after Preamble of claim 1.
  • a transfer press is in EP-A-0 383 168 described by the applicant.
  • a step press according to the preamble of claim 1 is known, the one Device for storing and / or changing the position of Workpieces in an intermediate stage, which also as Orientation station is called. This can Workpiece both in its height and in its position to be changed.
  • EP-A-0 383 168 improves such a storage device in an intermediate stage in that at a Large part step press a variable position of the workpieces in the individual tool levels is made possible, whereby especially the requirements for cramped spaces Space between the individual tool levels due to the storage device or Clipboard is taken into account. It sees this known large-section press before that for one large individual parts such as side parts, roofs or Floor panels of a motor vehicle in an orientation station or Storage device with adapted to the workpiece contour Filing templates can be edited (see Fig. 8 the EP 0 383 168). Provided by the variable large part step press smaller parts such as side doors or the like To be processed, this happens in the intermediate stage for example with two arranged in parallel Storage devices (see Fig. 7 of EP 0 383 168).
  • the known large part step press according to EP 0 383 168 has consequently the advantage that in the Clipboard stations between the tool levels both Large parts as well as smaller workpieces can be stored can, with any degree of freedom to change the position To be available.
  • the high apparatus is disadvantageous Effort in the clipboard level and its conversion process from large-area to smaller double workpieces corresponding workpiece change in the press.
  • the invention is therefore based on the object To propose transfer press or also large part step press, which can be used flexibly both for large parts as well as for smaller parts with corresponding variable Single or multiple arrangement of tools in the Processing stages, being a universally applicable Storage device or orientation station between the Tool levels are created that are suitable for both large parts can also be used for several small parts.
  • the present invention is based on the main idea that only a universally usable storage device for large workpieces as well as for small workpieces Workpieces is used and that during the conversion process of large areas on smaller workpieces or vice versa the storage device has to be changed as little as possible, where it is ultimately only due to the mandatory change of the on the Arranged workpiece templates arrive.
  • stencils must be flexible to the workpiece size be adaptable, depending on the number of workpieces on the Storage device a flexible change of position of all Storage templates are made.
  • the basic idea of the invention therefore lies in the storage device or Orientation station universal and flexible to accommodate one or more workpieces, each with its own Lay out templates that are independent and separate can change the workpiece position from one another. This has the advantage that with several Workpieces do not have several storage devices, e.g. two adjacent storage devices in the Intermediate must result, resulting in a leads to significant simplification and cost reduction.
  • the workpieces on the clipboard can be in one to five Degrees of freedom can be changed. There are corresponding ones Drives and facilities to implement this Change of location provided.
  • Adjustment means which change the position in perform any degree of freedom. These are for example one in the transport direction of the workpiece longitudinal movement, a lifting movement and a corresponding swiveling movement in and against the Direction of transport of the workpiece. These movements will be advantageously for both large and smaller workpieces with a common drive associated drive means executed.
  • Will the Storage device or orientation station e.g. with a large workpiece operated, so a common large or two stacked workpiece pallets with appropriate templates are used, the at Large parts usually only in and against Transport direction must be pivoted so that a Transverse movement is usually unnecessary. Of course, such can also be transverse Pivotal movement can still be provided.
  • the invention further provides that the for Most of the intended workpiece storage supports or Stencil carriers can be divided into, for example two template support sections, each of which then Serve a workpiece.
  • everyone Template support section is opposite to that Workpiece transport direction can be moved across the press stored and, if necessary, an additional Swiveling movement in the transverse direction Carry out workpiece transport direction.
  • the invention further provides that the Workpiece holder or template holder in your assembled form of the filing device or Orientation station can be removed to them For example, to provide new workpiece templates.
  • the workpiece holder with the templates can then be used move the sliding tables out of the press to be converted to become.
  • Transfer press 1 consists of several processing stages 2, 3 with processing tools, not shown, which as Individual tools for a single workpiece or from several side-by-side tools for several workpieces can be formed in a press stage.
  • FIG. 1 shows the Storage device in the direction of workpiece transport the heat press. This direction is 6 in FIGS. 1 and 3 specified.
  • the storage device or orientation station 5 points in accordance with 1 and 3, a plurality of drives to change the position of a workpiece placed on it or several workpieces.
  • the peculiarity lies here in that with one and the same storage device either a very large workpiece, e.g. a side part, a Roof, a floor panel or the like of a motor vehicle can be manipulated or with the same Storage device according to the changed representation in Fig. 2 several smaller parts as double parts or Quadruple parts such as Doors of a motor vehicle, etc., the come from corresponding multiple tool levels.
  • Fig. 1 The arrangement in Fig. 1 is used to store a large area Item, which is not shown in detail.
  • the storage device according to FIG. 1 is largely constructed symmetrically to the longitudinal center plane 7 and has one stationary base frame 8 on which there is a sled 9 for a movement of the storage device in and against the Transport direction moved.
  • An associated drive motor 10 serves this movement process via a corresponding one Deflection gear with spindle 11.
  • the lifting and lowering movement within the storage device 5 takes place via a lifting drive 12 with a cardan shaft 13, Deflection gear 14 and a vertically aligned spindle 15, with a lifting column 16 in associated vertical guides 17 is performed.
  • a supporting frame 18 is arranged on such a base, which in turn carries a pivot frame 19.
  • Guide carriages 20 with guides 20 ′ are arranged on the swivel frame 19 and are oriented transversely to the transport direction of the workpieces.
  • On this slide 20 there are two swivel drives 21, 22 at a distance l 1 from the longitudinal center plane 7, which can be moved in the transverse direction in the guides 20 'on the slide 20.
  • Drive motor 23 with spindle 24 and a corresponding spindle nut 25 are used for this purpose.
  • the two swivel drives 21, 22 have an in Direction of transport of the work pieces lying drive shaft 26 on, at the two shaft ends 27, 28 one each Docking device 29 for one workpiece storage support 30 each or also template carrier 30 is provided.
  • the Workpiece template 31 is shown schematically in FIGS. 3, 3a and 5.
  • the drive shaft 26 can be driven by the drive motor 32 be twisted (arrow 33), but only for the Embodiment according to FIG. 2 is decisive.
  • the Workpiece storage support 30 consisting of two support sections 36, 37, via a staking device 38 in the area of The longitudinal center plane 7 can be connected to one another.
  • This Stakeout or coupling 38 is used to plug together the carrier sections 36, 37 when changing tools and in the Trap where only a continuous stencil holder is required if only a large part is to be deposited. In this case the pivotal movement around the drive shafts 26 overridden.
  • the two carrier sections 36, 37 can move apart in the transverse direction by means of the drives 23 to 25 (position l 2 ), as shown in FIG. 2 is shown.
  • the pivoting movement (arrow 33) can then be activated, so that the carrier sections 36, 37 can each be pivoted independently of one another in the transverse direction to the workpiece transport direction, as shown in broken lines in FIG. 2.
  • the swiveling movement according to arrow 33 takes place by a rotational movement of the shaft ends 26 in operative connection with that of the swivel drives 32.
  • the setting out device 38 can be made from a bolt 39 on Carrier section 37 consist of a corresponding Bore or groove 40 can be locked in the carrier section 36 intervenes (Fig. 1). In this case, the carrier sections 36, 37 combined to form a carrier section 30 (FIG. 1).
  • FIGS. 1 and 2 By the alternative positions of the invention according to FIGS. 1 and 2 can therefore large workpieces with a common template carrier or with a shared assembled template carrier 30 according to FIG. 1 or smaller parts than double parts or quadruple parts with one divided stencil carrier with carrier sections 36, 37 according 2 and 3 in the clipboard on the Storage device 5 or orientation station manipulated become.
  • the press is converted to produce other workpieces in the processing stations 2, 3, in addition to the Tool changes on sliding tables 41 in general also Replacement of the workpiece holder or template holder 30 with templates 31 to adapt to a changed Workpiece geometry.
  • the Template carrier 30 removed from the orientation station 5 become what is generally by staking out on corresponding staking devices on the sliding tables he follows.
  • the pivot arms 48, 49 consequently pivoted into the clipboard 4, like this is shown in dashed lines in Fig. 5.
  • the entire storage device 5 in and against the workpiece transport direction according to arrow 6 be moved to stake out the template carrier to support the gripper arms 46, 47 if necessary.
