Detailed Description

The present invention will be described in detail with reference to the following embodiments.

A mineral separation bagged medicament conveying control system comprises a plurality of roller conveyor sets 1 and an electric control module 4, wherein each roller conveyor set 1 is provided with an independent forward and reverse rotation driving motor 6, part of the roller conveyor sets 1 are provided with steering motors 5, an infrared sensor 2 is arranged at the head and tail position of each roller conveyor set 1, and an infrared sensor reflecting plate 3 matched with the infrared sensor is arranged at the opposite position of each roller conveyor set; the electric control module 4 comprises a frequency converter and a PLC (programmable logic controller), the PLC can read data of the infrared sensor 2 and realize control of the plurality of roller conveyor sets 1, and the frequency converter is matched with the forward and reverse rotation driving motor 6 to adjust the conveying speed and forward and reverse rotation of the roller conveyor sets; the PLC can read the working times of any infrared sensor 2 and count the passing medicine bags 7 to realize the quantitative dosing function; the roller conveyor assembly 1 with the steering motor 5 is capable of 90 degree steering.

As shown in figures 1-2, the invention uses an electric control module 4, which comprises an electric module such as a frequency converter and a PLC to control a plurality of roller conveyor sets 1 to stop, rotate forwards, rotate backwards, turn 90 degrees and the like to finish various conveying requirements of bagged medicines, an infrared sensor 2 is matched with an infrared reflection plate 3 to judge the position of a medicine bag, and the head end and the tail end of each roller conveyor are provided with infrared sensors to realize the judgment of the position of the medicine bag under different conditions of the forward rotation and the reverse rotation of a conveying system. The forward and reverse rotation driving motor 6 can adjust the speed and forward and reverse rotation under the control of a frequency converter in the electric control module to meet different requirements of a roller conveyor unit for conveying medicine bags to a medicine stirring tank or a stacker crane, and the steering motor 5 is only arranged on the steering roller conveyor unit and can drive the roller conveyor unit to steer 90 degrees to realize 90-degree steering of the conveying device.

When the bag feeding device is used, as shown in fig. 2, when outsourcing bags 7 are conveyed from south to north, the driving motors 6 of each group of roller conveyor units run, the speed can be adjusted through the frequency converters, if the external unloading speed is low, the rotating speed of the motors is adjusted by the frequency converters to be slower, if the unloading speed is higher, the adjusting speed of the frequency converters is accelerated, and the stable operation of a conveying system is ensured. The infrared sensors 2 are installed at the head end and the tail end of each group of roller conveyor units, as shown in the example, when the conveying system runs from south to north, the sensor at the north end is in effect, for example, if a medicine bag is arranged on each group of roller conveyor units, the infrared sensors 2 cannot receive the signal reflected by the reflector 3, and the roller conveyor from south to north stops running temporarily through the PL controller.

Assuming that the extreme end of the south-north direction roller conveyor is provided, the infrared sensor 2 can not receive the reflection signal after the medicine bag blocks the infrared sensor, the sensor is in the off state, the PLC receives the signal and judges that the medicine bag reaches the end, the signal is output to the electric control system through program control, the group of driving motors 6 is temporarily stopped to operate, the PLC sends a rotation instruction to the steering motor 5 when the south-north direction end motor stops operating, when the steering motor turns 90 degrees, the conveying system sends an operation instruction to the south-north direction end motor to convey the medicine bag to the steering roller conveyor unit, when the infrared sensor on the steering roller conveyor is blocked, the system judges that the medicine bag is on the steering roller conveyor, the system sends an instruction again to turn the steering conveyor to rotate 90 degrees reversely, and after the steering roller conveyor turns to the position, the driving device of the steering conveyor conveys the medicine bag to the lower group of east-west direction roller conveyor, when the medicine bag is conveyed away, the infrared sensor normally operates, the rotary drum conveyor rotates back again, and according to the principle, the bagged medicines are respectively conveyed to the western-direction stirring tank or the east-direction stacking area.

When the conveying system conveys from west to east and from south to north, the PLC system only judges whether the infrared sensors at the east end and the north end of each group of roller conveyors are in effect, and when the conveying system operates from east to west and from north to south, the PLC system only judges whether the infrared sensors at the west end and the south end of the roller conveyors work or not.

The PLC controller can read the working times of any infrared sensor, and counts the passing medicine bags, thereby realizing the quantitative dosing function.

Whether a medicine bag exists on the roller conveyor unit is judged by an infrared sensor arranged at the rear end in the operation direction, when the roller conveyor has the medicine bag and does not go to the next step, the roller conveyor at the section automatically stops, the system judges whether the medicine bag exists on the previous roller conveyor, if so, the conveyor at the section stops operating, and the like. If no medicine bag is arranged on the rotary drum conveyor, the rotary drum conveyor can be turned to receive the medicine bag at the previous stage, and then the rotary drum conveyor is turned again after receiving the medicine bag and then conveyed to the conveyors in different directions to carry out next circulation. The PLC program is programmed to ensure that the medicine bags are not stacked and collided, the program logic is strict, and the whole system is reliably interlocked

The invention has the advantages of strict conception, close matching of various used devices, stable work and high reliability, and is very suitable for various ore dressing medicine bag conveying systems.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention. It should be noted that other equivalent modifications can be made by those skilled in the art in light of the teachings of the present invention, and all such modifications can be made as are within the scope of the present invention.
