FIG. 5 is a block diagram for the electronic position
sensing and control of the bale opener according to the
invention.
Turning now to the block diagram of FIG. 5, there is
illustrated therein a control device 29 such as a stored
program control connected with an inputting device 18.
A travel-position determining device 19, such as an
incremental rotary transmitter or the like is arranged at
the motor 20 for determining the longitudinal (X)
coordinates and a position determining device 21 such
as an incremental rotary transmitter arranged at the
motor 22 for determining the height (Y) coordinates.

Furthermore, the control device 29 is connected
with the intermediary of an amplifier 23 with the
drive motor 20 and with the intermediary of an
amplifier 24 with the lifting motor 22.
Also, the following additional components are
connected to the control device 29: a motor 25
which moves the detaching assembly 7 about a
horizontal axis to execute pivotal motions as
indicated by the by the arrows D, D' with the
intermediary of an amplifier 26, a device 27 for
determining the angular displacement of the
detaching assembly 7, a memory 28 as well as the
optical barriers 12, 13 ,14.

16. the apparatus for opening and
mixing staple cotton according to the
present invention comprises at least
two adjoining vertical chambers 1 and
1' which are alternately supplied, by the
conveyor 2 and counter-rotating
cylinders 3, with staple cotton material
conveyed through the duct 4 by a
negative pressure.
As the cotton being supplied arrives
at the level of a sensor 6, for example a
photocell, an actuator device will cause
the baffle or baffle pair to rotate so as to
discharge the staple cotton into the
other chamber.
This chamber should also comprise
a suitable sensor adapted for driving
the mentioned actuator device to cause
said baffles to return to their starting
position.
