专利说明:

The present invention relates to a handling device for handling objects with the features of the preamble of claim 1, an arrangement of such a handling device and a machine cooperating with the handling device, a method for controlling or regulating a handling device with the features of the preamble of
Claim 19 and a computer program product.
Handling devices known from the prior art for handling objects have an end effector. This end effector is designed to receive the object to be handled, with the most diverse design variants of end effectors being known, such as
for example hand-like grippers or vacuum grippers.
End effectors of a handling device generally have a drive train by means of which they can be controlled or regulated with respect to a base of the handling device. The control or regulation
of the drive train takes place via a control or regulation unit.
In most cases, these drive trains are formed by electrical drive units or also by pneumatic drive units, with the articulation points of a kinematic chain that connects the end effector to the base of the
Handling device connects, are movable.
The control or regulation of the drive train of a handling device takes place via a control or regulation of the individual drive units, which are mostly designed to vary a joint alignment of the handling device. This open-loop or closed-loop control of the individual drive units can be calculated using known computational methods by using the backward transformation (or also called inverse kinematics) on the basis of the handling device through a desired receiving, transferring, depositing or other position to be achieved by the end effector
is calculated back.
Handling device used as a reference.
The connection between the end effector and the base of the handling device is also known as a kinematic chain. To calculate this, the end effector, the individual joints and the base are assigned a coordinate system, the individual coordinate systems being defined in relation to one another by an orientation, a translation vector and a rotation matrix (mostly summarized in a 4 x 4 transformation matrix). However, the positioning of the end effector can also be done in this way
can be calculated against any reference to be selected.
Depending on the place of use, the base of the handling device is usually connected to a machine that cooperates with the handling device or is also attached to another surface. However, it is important that the base of the handling device is firmly and rigidly fastened at the place of use so that the base occupies a precisely defined point in relation to the environment so that the end effector can be controlled or regulated on the basis of the defined base in relation to the environment (to control defined recording or storage positions)
as precisely as possible.
In the example of a molding machine which is designed as an injection molding machine, the base of the handling device is often mounted on a fixed platen or is formed by this. In this context, molding machines can be understood to mean injection molding machines, transfer presses, presses or the like, a first example of the problem being presented below using an injection molding machine, although this generally applies to molding machines or with the handling device
cooperating machines can be turned over.
The coupling at the base of the handling device opposite the
Injection molding is usually done by adding the base of the machine
Handling device on the injection molding machine.
In the usual case, when used in injection molding machines, the handling device is mounted on a fixed platen, but it is also fundamentally conceivable for the handling device to be mounted on a moving one
The platen is mounted.
However, due to the build-up of the clamping force or during a closing movement (or an opening movement), the mold clamping plates tilt. This tilting results from the high clamping forces and / or, in the case of other movements, from the inertia of the moving components which, due to the forces acting, lead to deformation of components of the injection molding machine (for example the mold mounting plates or guides). The deformations lead to tilting of the mold mounting plates, which of course affects them
Affected base of the handling device.
This tilting movement or deformation due to the closing force or a dynamic movement during the injection process of the injection molding machine is transferred to the base of the handling device, this base being tilted and / or shifted by the deformation or tilting
whole handling device leads.
As a result of the movement of the base, the position of the end effector changes in relation to the storage or receiving position to be reached. This change is not only dependent on the clamping force or the magnitude of the acceleration,
but also from the axis positions of the handling device.
The same effect occurs, for example, if there are several
Handling devices share a base. In this case, the
Position of the other handling device.
With the movements and load changes described, reaction forces are to be expected in the base of the handling device, these reaction forces leading to deformations in the base or in elements of the handling device itself. These deformations of the base or of elements of the handling device itself have an effect on the other handling device. More precisely, the deformations have a direct effect
on the position of the end effector of the other handling device.
Generally speaking, handling devices are exposed to the dynamics of a manufacturing environment with their base. For example, if the handling device is arranged in front of, on or in the vicinity of a production machine, it can be assumed that the handling device is in its base through vibrations which are released into the environment by the production machine due to production
Positioning accuracy and its repeatability is impaired.
In more general terms, the handling device is generally exposed to the ambient conditions, with deviations in position of an end effector due to dynamic influences of the base of the handling device in the case of even minimal changes in orientation. It can be assumed that the kinematic chain that connects the end effector with the base is at least minimal in certain positions
The change in orientation of the base intensifies, which can be seen in the end effector. It is therefore known from the prior art to use mechanically sophisticated systems as the basis of a handling device
To attach degrees of freedom to cooperating machines.
This emerges, for example, from EP 0 995 575 B1, which a
Guide frame describes with which a handling device on a
Act on the basis of the handling device to compensate.
The disadvantage here, however, is that there is a certain amount of play between the handling device and the injection molding machine due to the additional bearing points, with increased inaccuracy for the end effector during positioning, since the position of the base of the
Handling device has an increased tolerance to the injection molding machine.
Another known possibility of the prior art is to train the handling device to the ambient conditions. For example, when used in injection molding machines, the handling devices are taught-in with a built-up clamping force, whereby the end positions - more precisely: the end effector coordinate system - is determined in such a way that it reflects the deformed, tilted or moved position of the base
the handling device compensated.
However, this approach also has some disadvantages. When the clamping force changes, the pick-up or deposit positions of the handling device must be taught (learned) anew each time, since these are from the
specific clamping force are dependent.
It can also happen in complex systems that the handling device is used for other tasks in the meantime due to waiting times, whereby these cannot be carried out exactly, since no deformation may have to be taken into account during handling in these interim times. In injection molding machines in particular, where clamping forces that vary from shot to shot can arise, such a procedure to compensate for deformations can only be carried out with a great deal of work (and even then only partially).
Regulation of the end effector possible.
This object is achieved by a handling device with the features of claim 1, with an arrangement with the features of claim 7, with a method with the features of claim 19 and with a
Computer program product having the features of claim 20 solved.
According to the invention it is provided that the at least one control or regulating unit of the handling device is designed to receive at least one signal characteristic of a movement - preferably tilting and / or displacement - of the base of the handling device and to receive the characteristic signal when controlling or regulating the Drive train too
consider.
The invention makes it possible to change the orientation of the base of the handling device when controlling or regulating the end effector by a
Control or regulation of the drive train to be taken into account.
The characteristic signal for a movement of the handling device can, for example, be a control signal of a machine cooperating with the handling device or of another handling device which has the same basis, whereby the control signals and the known geometric dimensions already have an impact on accelerations, deformations or other effects closed on the base of the handling device
can be. This knowledge can already be used when controlling or regulating the
Drivetrain a compensating movement can be carried out so that the
End effector independent of a movement of the base or a tilt

Path accuracy can be moved.
The effects of the acceleration and the inertial forces of the handling device itself can also be taken into account in the control or regulation. A movement or acceleration of the handling device also leads to a movement or tilting of the base, since a support or an area to which or to which the base is attached also has a certain elasticity, which means that when a force is introduced through the base, deformation ( and thus tilting
or movement of the base).
For example, it can be provided that the characteristic signal provides information about a subsequent oscillation or oscillation of the handling device itself, which is caused by an acceleration or movement of the handling device, this also being done via the controller or
Control of the drive train can be compensated.
The drive train can be provided to move a kinematic chain connecting the end effector to the base. The drive train can have several drive units. Drive units can, for example
be formed by electric motors or pneumatic drive units.

It can be provided that a further machine cooperating with the handling device is designed to compensate or compensate for a movement of the end effector of the handling device caused by a movement of the base of the handling device.

It can advantageously be provided that the control or regulating unit is designed to take the characteristic signal into account with the aid of inverse kinematics. The inverse kinematics is also known to the person skilled in the art by the expressions
"Backward transformation" or "inverse kinematics" are common.
The regulation or control of a handling device is usually carried out on the basis of a defined reference point or a defined reference coordinate system (hereinafter referred to as “reference” for short), the end effector having a certain orientation and distance to this reference. In the same way, based on this reference,
the displacement or tilt of the base can be determined.
For example, the base of the handling device can be used as such a reference. However, the reference can be freely selected, provided that at least one controllable or regulatable axis is provided between the reference and the end effector, the reference can be shifted or tilted
be balanced, compensated or used compared to the end effector.
The area of the handling device that connects the handling device with the environment, the place of use or a cooperating machine is referred to as the base of the handling device. The
The base can for example be designed as a flange for screwing.

different programs is trained.
It is preferably provided that the characteristic signal is a process variable and / or a process state of the machine cooperating with the handling device.

A calibration of the computational relationship or the setting of the look-up table can take place, for example, by means of a measurement. This is natural

1 shows a first exemplary embodiment of a handling device 13 for handling objects 10, an object 10 being able to be picked up, transported and deposited by an end effector 9 (provided as a gripper in this exemplary embodiment). In this exemplary embodiment, the handling device 13 is attached with its base 4 to a fixed platen 1 of a molding machine 15. In this embodiment, as
Reference the base 4 of the handling device 13 has been chosen.
The end effector 9 is connected to the base 4 of the handling device 13 via a kinematic chain, which in this exemplary embodiment is formed by two arms 5 and a hand axis 6. The drive train of the
Handling device 13 consequently has at least three drive units,
by which the first degree of freedom qx of the first arm 5, the second degree of freedom qy of the second arm 5 and the third degree of freedom q of the hand axis 6 are controlled
and / or can be regulated.
To control or regulate the handling device 13, a control or regulating unit 17 is provided which is connected to the individual components of the handling device 13 in a signal-conducting manner (shown by the dashed line). Furthermore, a sensor 8 is provided on the handling device 13, which can determine a movement and / or a force acting on the handling device 13. These sensors 8 are usually as
Accelerometers formed.
The molding machine 15 of this exemplary embodiment has a fixed platen 1 and a movable platen 2 movable relative thereto (each relative to a machine frame 12). The movable mold mounting plate 2 can execute the closing movement qm (or in the same way an opposite opening movement), which is carried out via the closing unit 3
can.
The clamping unit 3 of the molding machine 15 is connected to the fixed platen 1 via the machine frame 12. In order to be able to determine forces acting on the components of the molding machine 15, force measuring sensors / are provided. One of these force measuring sensors 7 is also arranged on the handling device 13. It is also entirely conceivable that the sensors provided as force measuring sensors 7 in this exemplary embodiment are used as gyro sensors, position sensors, acceleration sensors or the like
are trained.
In order to control or regulate the molding machine 15, it is connected to a control or regulating unit 16. The signal-conducting connection between the shaping machine 15 and the control or regulating unit 16 is in this
Exemplary embodiment shown by the dashed line. The tax-
or control units 16, 17 can interconnect by a signal-conducting
Communication connection (shown by the dashed line).
In Fig. 2, the embodiment of Fig. 1 is shown under the application of a clamping force, whereby the movable platen 2 was brought to the fixed platen 1 by the clamping unit 3 and a pressure force was built up between these platen 1, 2, which as a clamping force Fs
is indicated.
The closing force Fs leads to a (exaggerated) tilting of the fixed
Platen 1 and the movable platen 2 at an angle
Ik-
This tilting by the angle qx leads directly to a tilting of the handling device 13, whereby - as can be clearly seen - the end effector 9 is moved from its desired position by the tilting by the angle qx. In order to better illustrate this, the handling device 13 is shown in dashed lines
Target position (without tilting by the angle qx) shown.
With a closing force F3 that is variable over time, precise positioning of the end effector 9 is very difficult because the deviation of the end effector 9 from a target position - as can be clearly seen here - from the magnitude of the closing force Fs
and the resulting tilt qkx is dependent.
However, as can be seen in FIG. 3, it is now possible through the control or regulation unit to determine the correction factors q, (t), qy (t) and ga (t) as a function of the time-variable closing force Fs (t).
The number of correction factors is of course dependent on the number of controllable or regulatable kinematic axes of the handling device. For example, a correction factor for each drive unit can be
kinematic axis of the handling device can be determined.
The control or regulating unit 16 of the shaping machine 15 can transmit a characteristic signal to the control or regulating unit 17 of the handling device 13 via the signal-conducting connection, which signal provides information about the temporally variable closing force F; (t).
The control or regulating unit 17 of the handling device 13 can determine the correction factors qx (t), qy (t) and ga (t) based on this transmitted characteristic signal by means of a stored relationship, a lookup table or a calculation, and an adaptation via the drive train of the handling device 13. Thus, despite the tilting of the base 4 of the handling device 13 due to the time-variable closing force F; (t), the end effector 9 of the handling device 13 can have a target position and a
Assume target alignment with respect to the environment (as shown by Fig. 3).
This relationship of the correction factors q, x (t), qy (t) and ga (t) to a time-variable closing force F; (t) can be established, for example, by a formula or a graphical relationship in the control or regulation unit 17 of
Handling device 13 be deposited.
Such a graphically represented relationship is shown, for example, by FIG. 4. It can thus be stored how large the correction factor q, (t) is to be selected for a target position P1 on the basis of a prevailing, time-variable closing force Fs (t). This graphical relationship can either be defined by an (exact) higher-order function (shown by the dashed line) or given by a linear function (shown by the solid line), the calculation of the correction factors being simplified by a linear function
and the computing power is reduced. 4 only shows the graphic representation of the correction factor q, (t). Such a relationship would also be for the correction factors qy (t) and qA (t) for a
Design as shown by FIGS. 1 to 3 to choose.
However, a translational and a
rotational movement (static and dynamic) of the shaping machine 15 and
the handling device 13 are calculated against a static model and the correction factors q, (t), qy (t) and qga (t)
be calculated.
Such an (elastic) model of the elements of the shaping machine 15 relevant for the build-up of the clamping force can be used to infer a tilting by the angle qx, with the aid of which the correction factors q, (t), qy (t) and
qa (t) can be determined.
Alternatively, measurement of the tilt by the angle qx is also conceivable. An externally attached measuring system could of course be used for this. So that this external equipment does not have to be constantly on site, it is necessary to save
Tilting as a function of the closing force F; (t) is conceivable in a table.
Such a measurement of a tilt by the angle qx is shown, for example, by FIG. A measuring sensor 11 is arranged in order to determine a position of the end effector 9. Examples of such measuring sensors are acceleration sensors, position sensors or optical sensors. To measure the deviation, the closing force Fs is now built up, as a result of which tilting occurs by the angle qx and the end effector 9 moves in its position, which
can be determined by the measuring sensor 11.
The geometrical relationships, which are known, can now be used to infer the angle qx and this can be clearly assigned to a closing force Fs. With such a measurement, the closing force F3 can run through a force profile and each closing force Fs (t) can be tilted by one
Angle qx are assigned.
If the tilt (as a function of the closing force) is known, the displacement of the end effector 9 caused by the tilt and a rotation of the end effector 9 with the aid of the inverse kinematics, taking into account the tilt by the angle qx of the base 4, can be performed by the control unit 17 of the handling device 13 are compensated, whereby the
Correction factors q, x (t), qy (t) and qa (t) depending on a closing force F; (t) result.
In a similar way, it is also conceivable to use the method described to assign a variable (dependent on the closing force Fs (t)) storage / receiving position
compensate.
If no measuring sensor 11 is available, the handling device 13 with its end effector 9 could also be moved into a desired storage / receiving position when the molding machine applies a first clamping force F; executes. This position could then be saved. The closing force Fs could then be changed by the shooting unit 3 and the end effector 9 of the handling device 13 could in turn be moved into this desired storage / receiving position, this position also being in turn
could be saved.
By interpolating these two positions as a function of the two associated closing forces Fs, a relationship between the correction factors could thus be established
qx (t), qy (t) and qu (t) and the closing force Fs (t) can be established.
However, an embodiment is also entirely conceivable in which the end effector 9 is “held” in a defined position and via a force measuring sensor system
Closing force build-up, a force acting on the end effector 9 is measured.
Correction factors q, x (t), qy (t) and gA (t) as a function of the closing force F; (t) could also be determined from this measured force.
However, deformations that affect the base 4 of the handling device 13 are not only to be expected when the clamping force is built up. This means that vibrations can also occur due to dynamic stimuli and elasticities in the system (plate deflection, frame deflection, ...). The effect of movements, accelerations and decelerations on the end effector 9 of the handling device 13 could also be corrected with a model of this elasticity
will.
If several handling devices 13, 14 are fastened together on a base 4, a movement, acceleration or load change of one handling device also influences that of the other. Depending on position, speed or
A change in load results in an elastic deformation of the common base 4.
Such an exemplary embodiment with several handling devices 13, 14 is shown by FIG. 6. Each handling device 13, 14 has a second arm 5, which has an end effector 9, with which an object 10
is movable.
The handling devices 13, 14 are via a common control
or control unit 17 controllable or regulatable.
If one of the handling devices 13, 14 now exerts an acceleration or picks up an object 10, the ubiquitous elasticity of components leads to a deformation of the base 4, which also changes the position of the other handling device 13, 14, as shown in FIG.
7 is clarified.
To compensate for this undesired change in position of the end effector 9, it can now be provided that the control or regulating unit 17 automatically moves the one handling device 13, 14 into the other
Handling device 14, 13 controls or regulates accordingly.
For this purpose, a corresponding computer program product can be stored in the control or regulating unit 17, which correction factor qx (t), qy (t) was calculated by signals from the sensors 8, 7 and to compensate for a deformation
the base 4 executes (as can be seen by Fig. 8).
