FIG. 5 is a block diagram for the electronic position sensing and control of the bale opener according to the invention.
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.

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.
