Definitions
- the invention relates to a device for weight compensation of the arms of a robot according to the preamble of claim 1.
- the object is to propose a device for weight compensation which makes it possible to balance the weight of the arms of a robot and the weight carried by the second or third arm.
- CONFIRMATION OPY Figure 1 is a side view of a first embodiment of the device.
- FIG. 2 shows a side view of a second embodiment of the device
- FIG. 3 shows a side view of a third embodiment of the device
- Fig. 4 is a side view of a fourth embodiment of the device.
- the robot shown has a bogie 1.
- a first arm 3 is pivoted about a horizontal axis of rotation 4 via a first shaft 2.
- This first arm 3 supports a second arm 6 rotatably about a horizontal axis of rotation via a second shaft 5.
- the arms 3, 6 are pivotable about their horizontal axes of rotation by swivel drives, not shown.
- a sprocket 7 is rigidly connected to the shaft 5.
- the first arm 3 rotatably supports a second sprocket 8.
- the two sprockets 7, 8 are connected to one another via a chain 9 in a non-positive and rotational manner.
- the axis of rotation 10 of the sprocket 8 is in Figure 1 in the extension of the connecting line of the shafts 2, 5 at a distance from the axis of rotation 4 of the shaft 2.
- a lever arm 11 is rotatably connected.
- a cylinder-piston unit 12 is articulated, the articulation point 13 of which is also an extension of the connecting line between the axes of the shafts 2, 5, but is at a greater distance from the axis 4 than the axis of rotation 10.
- This articulation point 13 moves on a Circular path when the arms 3, 6 are pivoted.
- the cylinder-piston unit 12 is articulated on the frame 1 below the axis of rotation 4.
- the articulation point 13 or 13 A can be displaced via a spindle along the lever arm 11 or 11 A in order to compensate for the weight detected and carried by the second arm 6.
- the greater this weight the further the articulation point 13 according to FIG. 1 is shifted to the left or the articulation point 13 A according to FIG. 2 to the right.
- the current consumption of the drive motor pivoting the second arm 6 is measured and the spindle drive is actuated as a function of this current consumption.
- the following description relates to the weight compensation of a third arm 19 which is pivotably articulated on the second arm 6 via a horizontal third shaft 15.
- a third wheel 16 is rigidly connected to this third shaft 15.
- the second shaft 5 rotatably supports a fourth sprocket 17.
- a chain 20 runs between the third sprocket 16 and the fourth sprocket 17.
- a fifth sprocket 18 is arranged on the lever arm 11 in a freely rotatable manner coaxially with the axis of rotation 10.
- a chain 21 runs between the sprockets 17, 18.
- the lever arm 11 rotatably supports a sixth sprocket 23, a further chain 22 running between the sprockets 18 and 23.
- the axis of rotation of the sprocket 23 is at a greater distance from the axis of rotation 4 of the shaft 2 than the axis of rotation 10 of the sprockets 8, 18.
- the third arm 19 is crescent-shaped.
- the articulation point 13 is displaceable over a spindle along the lever arm 11 in order to compensate for the weight which is gripped and carried by the third arm 19. The greater this weight, the further the articulation point 13 is shifted to the left according to FIG. 1 and to the right according to FIG.
- the current consumption of the drive motor pivoting the third arm 19 is measured and the spindle drive is actuated as a function of this current consumption.
