The PPU-P Pick and place unit.
The unit is fastened from below ...
... with screws and pins.
Therefore, the two threads are used, ...
...and the intermediate locating holes.
The PPU-P can be fastened and fixed from below...
... with a base plate.
With the optionally available base plate ...
... fastening can be simplified.
The pick and place unit is placed upside down first.
The two supplied locating pins are inserted ...
... into the pin holes between the two threads.
Now the base plate is put on top and connected with screws.
Then the PPU-P can be easily connected from above ...
... with a carrier plate with screws and pins.
Attachment of loads to the cantilever arm ...
... is done from the front or from below.
For centering purposes, please use ...
... the supplied centering sleeves.
Thereby consider the admissible range ...
... of the load's center of gravity.
For details see our operating manual ...
... which can be downloaded from our web site.
For further operation remove the front panel.
Loosen the screws pointed out with the green Allen-key.
Dp not loosen this screw!
The individual screw fastens a special key ...
... which otherwise might be lost.
Draw out the sensor cables from the housing ...
... for having enough work space.
At the indicated screw connections ...
... the air hoses are connected later.
The air hoses are just inserted.
When the PPU-P is shipped, ... 00:03:22,00:03:26 ... the connection of the 3 throttles is closed.
Slightly open them for further operation.
By adjusting the two curved plates ...
... the horizontal front and rear end position are adjusted.
Unscrew the 3 fastening screws per curved plate ...
... on the back of the PPU-P. 00:04:35.00:04:40 Put the cantilever arm into the lower front end position.
Now this position is adjusted.
Then we put the PPU-P into the rear end position, ...
... and adjust it correspondingly.
Then tighten the locating screws on the back again.
Therefore we need the special key ...
... for adjusting both vertical end positions.
For adjusting the vertical position of the rear end position, ...
... the cantilever arm is put into the correct position, ...
... then it is tightly pressed into this position. 00:05;34.00:05:38 The stop sleeve is unscrewed with an Allen key, ...
... and can be adjusted with the special tool. 00:05:59:00:06:03 After adjustment of the vertical end position, ...
... the stop sleeve has to be clamped again.
The front end position is adjusted in the same way.
For monitoring and controlling the pick and place process, ...
... the sensors have to be adjusted.
Therefore a sensor tester is used.
The SCHUNK SST for example.
1.) The sensor has to be adjusted for the lower rear end position.
The two sensors have to be moved upwards within the groove ...
...for reaching the rear position.
2.) We connect the sensor ...
... to the sensor tester.
The PPU-P is put into the lower rear end position, ...
... push it down, loosen the fixation, ...
... move the sensor from bottom to top until it lights up, ...
...move it another half millimeter and fix it again.
Then the sensor is adjusted for the lower front end position.
Connect the sensor tester with the sensor ...
... move the PPU into the lower front end position ...
... and push it down.
Move this sensor from bottom to top ...
... until it lights up, move it another half millimeter, ...
... and fix it again.
Now the sensor is adjusted for the change-over-point ...
... of the horizontal drive.
Now adjust a caliper to 15 mm.
Fix the sensor with an outside dimension of 15 mm ...
... in relation to the higher attached sensor.
Adjust the PPU cantilever at the highest position ...
... of the cycle motion, and then move this sensor ...
... until it lights up. Then move it another half millimeter, and fix it.
In this groove the horizontal position ...
... can be interrogated via magnetic switches.
Via the throttles, the speed of the motion is adjusted.
See also the specifications of our operating manual.
For further optimization of the motion, ...
... the stoke of the shock absorber can be reduced.
Therefore, loosen the lock nut with the special tool.
The sensor is loosened with a pair of tongs ...
... from the sleeve, ...
... and then it is fixed again with the nut.
A sufficient path for the shock absorber ...
... is needed for a bounce-free return to the end position.
With the 4 lubricating nipples ...
... the PPU can be quickly lubricated ...
... in case of a later maintenance work.
Now the cover of the housing with the attached ...
... special tool is fastened again.
