A travel-position determining device 19, such as an incremental rotary transmitter or the like is arranged at the motor 20for 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.CONTROL OF VERTCAL CHAMBERS OF OPENNG AN MXNG UNT 1 and 1-vertical chambers2-conveyor3-counter-rotating cylinders 4-duct5-bafe (bafe pair)6-photocell sensor7-gripping cylinder8-opening cylinder9-cleaning blades10-stationary plate11-vertical manifold12-vacuum ductthe 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 arrivesat the level of a sensor 6, for example a photocell, an actuator device will cause the bafe or bafe 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 bafes to return to their starting position.CLOSED LOOP SYSTEM OF CONTROLLNG OPENNG AND MXNG UNT N SPNNNG MLLOPEN LOOP SYSTEM OF CONTROL OF BALE OPENER
