  • a transport device known from EP-A-693334.
  • DE 44 08 447 A1 describes a transport device for transport of workpieces, where the transverse transport of a Transport carriage on a side member as well The workpiece is moved on a column. to Carrying out these movements are two belt systems required a rigid in their movement Generate motion profile. The stroke and longitudinal movement of the Workpiece is fixed due to the arrangement of the belt drive specified. A comparable arrangement is in DE 32 33 428 C2 shown. Finally, the publication also shows: IBM Techn. Disclosure Bulletin, Vol. 14, No. 8, Jan 1972, pages 2375-2378, Drive variants with endless rope drives. By shift The movement of a positioning table is triggered by axes. The application was for data processing to control Data output devices, such as. B. X-Y pen plotter.
  • the object of the invention is to create a transport device which is as simple as possible in terms of construction and which is universally suitable for transporting workpieces, preferably in or on shaping devices of all kinds, it being possible to work at high transport speeds, in particular with low drive power and small transport masses.
  • This object is achieved on the basis of a transport device according to the preamble of claim 1, by the characterizing features of claim 1.
  • Advantageous and expedient developments of the transport device specified in the main claim are specified in the subclaims.

  • the movement of the boom is influenced by two motors, their direction of rotation and their speed of rotation to each other influence the movement of the boom.
  • the movement of the boom in a vertical plane can be controlled arbitrarily, d. H. any movement profile in a vertical plane in both horizontal and in vertical direction is controllable.
  • Using a highly dynamic Control of the two motors allows all motion profiles cope with only one drive train.
  • the drive train is in its independent drives Sequence of movements, speed and direction of movement influenced, whereby the desired driving curve is achieved.
  • the transport device can be used for a Press automation for a wide variety of transport tasks for press lines as well as for large section presses take over such.
  • FIGs 1 to 3 two individual presses 1, 2 are one Press line, in Fig. 4 a transfer or large part step press 3 shown.
  • the presses 1, 2, 3 include one Head piece 4 and side stands 5, 6, one intermediate press ram 7 with upper tool 8, one opposite lower tool 9 on a sliding table 10.
  • the respective processing stage is identified by reference numerals 11 and 12 in Figures 1 to 3 or 11 to 14 in Fig. 4.
  • a filing stage 15 are located between the individual processing stages 11 and 12 to accommodate replaceable suction spiders or cross beams with suction spiders.
  • the transport device 16 is located between the individual processing or forming stages 11 to 14, as shown in Figures 1 to 4.
  • there 1 shows the transport device 16 in one Removal position of the workpiece from the first processing stage 11, while the representation according to FIG. 2 is a medium one Parking position of the transport device 16 between the Shows processing stages.
  • 3 shows the Transport device 16 in its movement sequence for storing the Workpiece 17 in the right processing stage 12. If the Workpiece transport by means of suction bars or by means of Suction spiders 18 equipped cross members 19 are two opposite transport devices 16 each between the individual processing stages provided together each a sucker bar or crossbar 19 wear.
  • FIG. 1a shows an enlarged view of the Transport device 16 in a position analogous to FIG. 1.
  • the transport device 16 is fixed on a stationary Mounting plate 20.
  • Two lifting columns 21, 22 are in vertical bearings 23, 24 stored.
  • the lower area of the lifting columns 21, 22 is with a horizontal cross member 25, the upper region of the Lifting columns 21, 22 are connected by means of a transverse yoke 26.
  • the mounting plate 20 is a kind of stationary drive block 27 formed with a first drive motor 28 and a second drive motor 29.
  • a pair of deflection rollers 31, 32 are provided in the horizontal cross member 25 .
  • the upper cross yoke 26 includes another pair of idlers 33, 34.
  • a Deflection pulley pair 35, 36 provided in the drive block 27.
  • the entire transport system is basically symmetrical constructed and reflected on the vertical plane of symmetry 38.
  • the traction device arrangement 30 initially serves to drive one Cantilever or support arm 39, which by means of bearings 40 on the stationary horizontal cross member 25 is longitudinally slidably attached. Only a single drive train 41 is provided for this.
  • the first end 42 of the drive train 41 is as shown in FIG 1a, 2a at the left end of the boom 39 at point 44 attached.
  • the second, other end 43 of the drive train 41 is at the opposite end (point 45) of the boom 39 attached.
  • the one-piece drive train 41 is now from point 44 on left end of the boom 39 on the pulley 31 in horizontal cross member 25 to the first drive motor 28 and from from there to the associated deflection roller 35 in the drive block 27 guided.
  • the drive train 41 becomes from this deflection roller 35 further led to the upper deflection roller 33 in the transverse yoke 26.
  • the drive train becomes a symmetrical arrangement of the device 41 'then returned from the upper deflection roller 34 in the transverse yoke 26 to the deflection roller 36 in the drive block 27 and over the second Drive motor 29 to the lower deflection roller 32 in the horizontal Cross member 25.
  • the drive train 41 'then ends in the right end of the boom 39 at point 45.
  • the arrangement of the respective Motors 28, 29 with the associated deflection roller 35, 36 can be exchanged.
  • the boom 39 can be a further boom 54 may be assigned so that the two booms 39, 54 form a so-called telescopic arm 55.
  • the Movement of the boom 54 is carried out in a known manner by means of a Belt drive 56 completed, the drive belt 57 over a drive motor 58 driven with two deflection rollers 59, 60 becomes.
  • this drive works with the corresponding Swivel device for the workpiece 17 is on the EP 0 693 334 A1 in particular Fig. 10 with associated Description referred.
  • By using the invention can also perform random movements of the workpiece transport with respect to a pivoting process of the workpiece as in FIG. 3 shown, done.
  • Fig. 4 also shows the problem-free application of the invention Transfer or bulk stage presses where the Transport device between the individual forming stations 11 can be arranged to 14.
  • the example here is Transport device shown with a single transport arm. Reference is made to the corresponding statements in EP 0 672 480 directed.
  • An alternative embodiment of the drives and pulleys compared to the representation of Fig. 1a, 2a can by a changed arrangement of the deflection rollers 35, 36 and 33, 34 be made or by changing the number of these Pulleys.
  • drive train Drive means are used, such as. B. timing belt or Chains.
