Definitions
- the invention relates to a transfer device.
- Such transfer devices are, for example, three-axis transfer devices, Insertion or removal feeder.
- E.g. from DE 33 29 900 C2 is a three-axis transfer device known, the two parallel to each other at a distance has arranged transfer rails. These are arranged along the part transport direction so that it the individual between each other using press tools include defined workstations.
- the transfer bars perform a transfer movement that is a lifting and Lowering component and one in the longitudinal direction of the transfer bar contains directed transport component.
- the transfer beams are used to hold the workpiece and Workpiece storage laterally towards or from each other moved away. Electrical are used to move the transfer bars Drives.
- the transfer bars are used to hold workpieces laterally adjusted so that corresponding gripper or Receiving means engage with the workpieces and record this. To do this, the transfer bar must be on the side into the open tool. After filing the Workpieces in the next open tool the transfer bars have to be moved out of the side of the tool before it closes again.
- the transfer device has mechanical transfer agent, the at least one Workstation supplied with workpieces and workpieces removed from this workstation and with that in mind the workstation is linked.
- the transfer agent is of several, at least two drive devices driven, coordinated, preferably work synchronously.
- the drive devices are through a coupling device connected to a selected one Has work area in which the power or torque transmission is low or zero.
- This work area is a passive area in which a mutual Influencing the drives is slight or excluded. If this is left, the coupling device transmits so much power or torque between the drive devices, that the movement of the transfer agent in the set time window and a collision between the means of transfer and facilities of the work station be avoided.
- the coupling device enables the independent Operation of the drive equipment so that it is not too Interference or interference between the two drive devices comes when operated properly become.
- a drive device does not work the passive area of the coupling device leave. This will make it the remaining one properly working drive means that Function of the drive device no longer working properly to take over. For example, a drive device falls off, the drive concerned remains no longer stand, but is via the coupling device from the properly operating drive device dragged along, at least until moving from the collision area.
- the means of transfer are preferably by two arranged parallel to each other Transfer bar formed, which is along a transport direction extend.
- the transfer bars span preferably several workstations and effect the Workpiece transport from station to station. To record of workpieces, the transfer bars move towards each other emotional. To release, they move from each other away from. These movements are from the two drive devices causes.
- Each pair of drives includes two drive devices, one below the other are coupled.
- the coupling agent is preferably a mechanical one Coupling means, for example a rotary coupling or a translatory Clutch.
- the coupling device has one Work area with low torque or power transmission on. This can be a play area. At a Swivel coupling, this is a rotating game. With a translational Clutch this is a translational game. In this play area can be the power or torque transmission be small. In any case, it falls below one Limit that is dimensioned so that the duly working drives practically unconnected are. This enables the drive devices in arrange control loops working independently of each other, each of which is given individually Adjust the setpoint, which can change over time. Control vibrations, control deviations also temporarily Nature does not cause the drive equipment to malfunction among themselves.
- the characteristic curve of the coupling means is therefore in the Ideally, a kink characteristic for a limit falling angle or path differences between no torque or power transmission with either drive having.
- the characteristic curve is axially parallel to one Angle or path axis in a torque (force) angle (path) -Diagram. Outside of this work area ideally, no increase in the angle or path difference more approved.
- the characteristic curve is parallel to here the torque (force) axis in the diagram above.
- the coupling device can also be used here have some compliance to the clutch engagement not too hard to shape.
- the angle of rotation or path difference can also a differential speed or differential movement speed as a criterion for engaging and disengaging the coupling device to be used.
- spring or damping devices to be ordered at the Coupling device. The invention enables in addition to Extend the transfer rails and gripper means the tool area an additional temporary Manufacturing operation, with then, if necessary, reduced Number of strokes (working speed)
- the coupling device self-controlled. However, it can also be controlled externally be and for example from an (electrical) Error signal can be coupled, which is one of the drives delivers.
- the coupling device can be procured in this way be that the existing workspace with low torque transmission to a smaller value or is limited to zero once it is exceeded has been.
- Such a coupling device can be used for operation with a possibly reduced number of strokes additional clutch included, the friction or positive snaps into place.
- filler pieces in the Coupling device can be used, the game decrease or make zero.
- the coupling device with sensor means connected that signal whether and when the selected specified work area is exceeded has been.
- These signals can serve as an error criterion serve for a higher-level control.
- the concept presented can be used for opening and Closing transfer bars by means of independent electrical Drives are used. It is also on drives applicable, the lifting and lowering or the drive effect in the direction of transport. In addition, a corresponding coupling device for non-electrical Find drives application. Both drives different transfer bars as well as one and the same Transfer bar coupled together in this way become.

- Via a ball bearing 39 is additionally mounted, which on a carrier 41 the base frame 27 of the lock case 18 is supported.
- a further drive 42 which each has an electric motor 43 and which is lifting and lowering the transfer bar 12, 14 causes.
- the Drive 42 With the Drive 42 becomes a corresponding one on two guides vertically slidably mounted slide 44 vertically moved up and down. The sledge movement is by corresponding push rods 45 on the intermediate carrier 32 transferred from the lock box in the lateral direction is driven.
- the arranged between the lock boxes 17, 18 Coupling device 37 is illustrated separately in FIG. 3.
- the core of the coupling device 37 is one Claw coupling 51, the coupling halves 52, 53 e.g. wear axial extensions 54, 55 with an angular play mesh between 45 and 175 degrees.
- the drives of the two lock boxes 17, 18 are so set the wings or claws 54, 55 of the coupling halves 52, 53 each in the middle of the gap between the claws of the other half of the coupling, without touching it.
- For centering is on the coupling half 52 an axial pin 56 by a bolt formed in an axial socket of the coupling half 53 takes hold. This makes the coaxial alignment of both Coupling halves 52, 53 also ensured when the Coupling halves do not transmit torque, i. H. in the Play area are set.
- the coupling half 52 is with a damper element 61 screwed. This has end plates 62, 63 with. Screws or bolts 64 on the coupling half 52 or a steel disc 65 are connected. This is about one Clamping coupling 66 with non-positive or positive locking connected to the shaft 38.
- the coupling half 53 is similar via a rotary damper 61 'and a corresponding clamping coupling 66' connected to the shaft 39.
- the electric motors 21, 22 are of a control and Control device 71 controlled, which is illustrated in Figure 4 is.
- Each motor 21, 22 works via its transmission 21 ', 22' to the respective threaded spindle 24.

These signals become a control loop 76, 77 fed.
- Each control loop 76, 77 points to this a summer 78, 79, which the sensor 74, 75 emitted position signal (actual signal) with a target signal compares. This is done by a control device 81 two control loops 76, 77 predefined equally. The signals are converted so that a default signal the control device 81 each the distance of the Output 31 determined by the longitudinal median plane 19.
- Both control loops 76, 77 operate independently from each other and both represent one another such state in which the actual signal is the target signal comes as close as possible.
- the corresponding serve Controller R which is designed as a P, as a PI or as a PID controller could be.
- the coupling device 37 is characterized, for example, by the characteristic curve shown in solid lines in FIG.
- the characteristic curve is understood as a torque-angle characteristic curve.
- the angle of rotation ⁇ is the rotation between the coupling halves 52, 53 or between the shafts 38, 39.
- No transmission takes place for a selected working area 91 which is arranged symmetrically to the zero point of the diagram.
- the working area 91 limits all the characteristic curves possible here to the transmission of a negligible torque, a so-called zero torque M N or -M N. This means that for all angle differences that are smaller than the difference rotation angle ⁇ 1, ⁇ -1 , no torque transmission is possible that is greater than this negligible torque M N , -M N.
- These zero torque values are so low that the control loops 76, 77 working independently of one another cannot interfere with one another.
- the characteristic curve section 82, 83 runs much steeper than in the area 91. It is preferably almost parallel to the M axis.
- the permissible range 93, 94 in which the characteristic curve section 82 can lie is delimited with dashed lines.
- the characteristic curve sections 82, 83 can also run somewhat flatter than shown. This is illustrated by dash-dotted curve sections 82, 83. It is essential that a torque is transmitted which is sufficient to rotate a failed drive, so that the transfer bars 12, 14 are opened quickly enough.
- both control loops 76, 77 the transfer bar position specified by the control device 81 independently.
- the control loops 76, 77 work practically independently of each other, however, in sync with each other. That’s where they come from Coupling halves 52, 53 are not engaged. In statistical The teeth of the coupling halves 52, 53 are in the middle exactly on gap. Occurring deviations and a Overshoot of individual control loops is normal Operation no greater than the clearance between the coupling halves 52, 53, so no power transmission over the coupling device 37 takes place.
- the motor 22 can thus be driven by simultaneous driving both threaded spindles 24 without the aid of the motor 21 move the transfer bars 12, 14 out of the tool area.
- the control loop 76 balances the higher load of the motor 21 by a correspondingly more powerful control the same.
- the motor 22 is dimensioned so that the higher burden at least for one Work stroke is survived without damage. Can if necessary the motor 22 can also be dimensioned so that with reduced Speed if necessary using a for Elimination of the game to be used in the coupling device Fitting or a lock-up clutch can be continued. So the entire press system e.g. finish at least one lot, before the failed drive is serviced.
- both threaded spindles 24 can also be used Wear right-hand thread.
- 14 is then on one A transmission 40a is arranged on the side of the coupling device 37. This has the gear ratio of 1: 1 and reverses the direction of rotation.
- Such an embodiment is illustrated in Figure 7.
- the shafts 38, 39 can be aligned with each other. If they like from 7 and 8 emerges, offset from one another are arranged, the connection between the shafts 38, 39 and the coupling device on one side of the Coupling device 37 or on both sides of the same via a transmission 40a, 40b. This allows according to Figure 6 in the same direction or rotating in opposite directions according to Figure 7 Shafts 38 39 are coupled.
- a coupling of two drives can also be done by coupling of linear movements to each other.
- Embodiments for this are shown schematically in Figures 8 and 9 illustrates.
- E.g. is after in the embodiment Figure 8 shows the translational movement of a rod 38a by a coupling device 37a to a deflection gear transferring lever 40c transferred.
- the coupling device 37a is replaced by one at one end of the provided in the middle of the pivoted lever, For example, a pin 52a formed in an elongated Opening 53a of rod 38a sits.
- the lever 40c is articulated with respect to the rod 38a connected in opposite directions rod 39a.
- the coupling devices 37, 37a described above are characterized by an existing play. You control the engagement and disengagement yourself based on the existing angle or path difference. However, it is also possible to externally control the coupling device 37. This is illustrated schematically in FIG. 10.
- the coupling device 37b which is used to couple two shafts 38, 39 as required, is normally in the disengaged state.
- a spring means 101 which is locked in the pretensioned state, is used for engaging. The arrangement is such that it can be released, its spring force then frictionally engaging the plates of the multi-plate clutch 37b, so that the shafts 38, 39 are coupled in a rotationally fixed manner.
- a mechanical control device 102 which has a control input 103, is used to trigger the spring means 101.
- the control input can be a mechanical or electrical, a pneumatic or hydraulic signal input. In the present example, it responds to an electrical signal that is derived, for example, from motors 21, 22 or controllers 76, 77.
- the characteristic curve of such a coupling device is illustrated in FIG. 5a. If a maximum path difference ⁇ x max is exceeded in the positive or negative direction, the control device 102 releases the spring means 101 forming a spring accumulator and the multi-plate clutch 37b engages.
- the multi-plate clutch 37b by a positive coupling, for example a claw coupling, replaced or be supplemented. It is possible that To provide claws with sloping surfaces when engaging a certain rotation of the shafts 38, 39 against each other bring about and thus a fixed position of the Bring waves 38, 39 in relation to each other.
- the spring means can also be any other energy store or drive may be provided.
- a transfer device 1 has at least one Transfer means 12, 14 on that with several of each other independent drives 17, 18 in the direction of at least one Axis C, O is driven. In the event of a drive failure 17, 18 an immediate stop of parts of the The drives 17, 18 are to prevent transfer means via an externally or internally controlled translatory or rotary coupling device 37 coupled together. This has a low torque transmission working range on who normally ingested and only is then left when one of the drives 17, 18 none sufficient drive power delivers more.
- drives of two-axis or three-axis transfer devices as well as drives can at e.g. Insert feeder or removal feeder devices be designed, with which the invention is not limited to one certain drive axis of a triple-acting transfer device is restricted.
- the clutch can thus be used in any drive train 6, 7 or 9 to illustrate.
