Definitions

  • the invention relates to a press line or large-part step press with a transport device to transport of workpieces according to the generic term of Claim 1.
  • press line or large-part step press are transfer devices for the transport of workpieces in the processing stages provided.
  • Earlier transportation systems saw longitudinal and controlled by cam drive Lifting movements, as well as possible transverse movements of the Transport devices from the main drive of a press were derived and thus synchronized to Ram movement (EP 0 210 745, Fig. 4).
  • Ram movement EP 0 210 745, Fig. 4
  • With newer ones Systems according to EP 0 672 480 B1 or EP 0 693 334 A1 the transport process takes place between individuals Processing stations individually by individual Transport devices, in particular a universal Movability of the workpiece transport between individual Enable processing stages.
  • From Central drive of the press completely independent drive or Can transport the workpiece with any degree of freedom the transport process of the workpieces, especially in larger ones Press lines can be optimized.
  • the Comments in EP 0 672 480 or EP 0 693 334 referred.
  • a transport device is known from DE 4 309 661 A1 become, in which in the longitudinal extension over the entire Press length, above the parts transport level, in height-adjustable slide mounted mounting rails are provided. These mounting rails are used for storage and as a carriageway for transport vehicles, each with its own independent drive systems.
  • the respective trolleys can be separated into several Degrees of freedom.
  • Brackets for cross members are integrated in the trolleys.
  • the crossbeams are with holding elements such as suction cups, pliers or magnets Workpiece pick-up and transport provided.
  • the crossbeams are each from two lateral Transport car stopped and moved. So it becomes a Transport system revealed at the horizontal on common arranged carrier rails self-propelled trolleys can be moved independently of one another.
  • the ones to be moved Masses are relatively large because the drives are not stationary are, but ride along.
  • the unpublished DE 199 11 759 shows a Transfer system for parts transport consisting of a Number of transport systems in a vertical arrangement arranged between the forming stages on the press stands are. Each of these transport systems has its own Drive system.
  • the invention is based on the idea in DE 199 11 769 drive system described so that horizontal mounting is also possible.
  • This horizontal cultivation is e.g. B. required if the Transport step because of the geometry of the workpieces is great that a vertical transport system Requires an increase in the press height.
  • On The fixed attachment of 2 drives ensures substantial reduction in the masses involved in the transport.
  • These drives are independent of each other in speed and Adjustable direction of rotation. In active connection with Movement transmission means overlap the movements and any programmable driving curve in one plane can be carried out.
  • Movement transmission means can preferably Pinions and racks can be used.
  • the drive systems are perpendicular to Part transport direction arranged offset to each other.
  • a major advantage of the proposed transport system is the simple adaptation to the required transport or Stride lengths even with the most varied Bulk presses. Only by changing the length of The guide rails and movement transmission means can Adaptation to the required transport step. Consequently is this by reducing the design effort a modular, low-cost system.
  • Each Transport unit can depend on the particular Ram or interfering edge position are optimally operated in terms of time, to achieve high cycle rates with short transport times.
  • Another advantage is that each system has its own Can walk stride lengths and speeds, i.e. the Acceleration values are dependent on the particular Selectable workpiece rigidity.
  • the stationary mounting of the drive motors is also favorable, this reduction of the moving masses enables a very dynamic transport system with low energy consumption.
  • the fact that the energy supply is stationary also has a favorable effect is arranged, what the absence of moving lines Functional reliability increased.
  • processing or forming stages are one Large part step press 1 shown.
  • the invention Transfer system 2 extends over the entire length of the press seen in the direction of transport. Drive and guides are in horizontal arrangement with attachment points Press stands 3 mounted. There is also one here Adjustment device 4 for central or groupwise move the transfer system 2 in the vertical direction. This Function may be required for tool change Avoiding a collision between the tool 5 and the Transfer system 2. It is therefore a pure one Setup axis. A height adjustment is another setup function transfer system 2 possible. Different Transport positions can be seen in the illustration. While in the forming stage 6.1 a workpiece is removed Transfer system 2.1 takes place next to the forming stage 6.2 the transfer system 2.2 in park position.
  • the Transfer system 2.3 is in a forming stage 6.3 in one Transport function with swiveled parts holder. Good The different position of the plungers 7 can also be seen, i.e. due to the flexibility of the transfer systems 2.1 - 2.3 the press can be operated with staggered rams become. The max. Pressing load on the forming forces is thus significantly reduced and thus the torque the drive shaft.
  • FIG. 2 shows that Drive concept of a transport system.
  • Actuators A1, A2 set gears 8, 9 in rotary motion or keep them in Resting position. These gears 8, 9 act on racks 10, 11 and thus influence their horizontal position.
  • the racks 10, 11 are operatively connected with the gear 12.
  • Rack 13 is by gear 12 driven and executes a vertical movement.
  • At the Articulation point 14 of the rack 13 are the actual ones Pick-up and holding device for workpiece transport attached, as described in more detail in the following figures. In the proposed arrangement can thus by regulating the Drives A1, A2 the pivot point 14 any point in reach an X-Y coordinate system with its driving curve.
  • Table 15 shows the movement options for the same Speeds of A1 and A2 and one each at standstill Drive. The representation does not include the multitude of Variants that are additionally different Speeds of A1 and A2 can be achieved.
  • X and Y are the Axes of a plane coordinate system and the arrows indicate the direction of movement depending on A1 and A2.
  • Table 15 shows an example at the same speed and same direction of rotation of the drives A1 / A2 a purely vertical (Y-) movement of the articulation point 14 and thus a lifting or Lowering movement of the transport system.
  • a motion overlay takes place through different speeds from A1 / A2 to to the extreme case that a drive does not perform a rotary movement, as can be seen from the last 4 diagrams.
  • Gears and racks are shown, but also meet other drive components, such as separately driven Toothed belt with toothed belt pulleys, the task.
  • the stationary drives 16, 17 generate the movement of Transfer system 2.1.
  • Drive 16 is connected to gear 18, which acts on the horizontally movable rack 19.
  • Drive 17 causes the horizontal movement via gear 20 the rack 21.
  • the racks 19, 21 are in Active connection with gear 22, 23 which the rack 24th drives.
  • Structure and function of the rack 24 is comparable to a lifting column.
  • the transfer system is in the plane of movement comparable to a cross slide built up, i.e. movably supported in 2 levels. Through this Structure are those described in more detail in Figure 2 Movements can be realized.
  • To hold the workpieces serves the cross mounted to the transport device with Traverse 25 provided with part holding means
  • the transfer system can accommodate and drive the traverse 25 2.1 mirror image additionally on the opposite Press side to be grown.
  • FIG. 3 A top view of Figure 3 shows Figure 4, in the rack 19 is not shown.
  • an essential constructive Characteristic is the spatial offset of the respective Drive elements of the transfer systems 2.1 and 2.2 can be seen. This arrangement ensures a collision-free Sequence of movements.
  • the gear 20 connected to the drive 17 therefore has a longer hub than the analog gear 20.1.
  • the gear 20 drives the rack 21, which thereby Gear 22 drives.
  • the rotation of gear 22 will over the common shaft 38 from the gear 23 on the Transfer rack 24.
  • FIG. 5 shows the adjustment and lifting device 4 and one Detail of the transport system 2 in a sectional view.
  • the Adjustment and lifting device 4 has the function that Transport system 2 to one, based on the tool, regulate the optimal transport height and on the other hand that Transport system 2 to avoid interference edges in the To move the tool change vertically upwards. This function can optionally be done for the entire transport system 2 or only for individual transport systems 2.1 - 2.n.
  • Drive 31 drives as an example Spindle nut system 32 and this leads to a Change in position of the mounting angle 33 in the vertical direction. In a horizontal arrangement this is on the angle 33 Transport system 2 stored, which is vertical for the entire Height adjustment required linear guide 34 attached.
