The invention also discloses a control method of the control device for the number of the medicine plates in the buffer area punched by the bubble cap machine, which comprises the following steps:
S01, placing the swing rod 51 at a free position, starting a rear main motor of the blanking and discharging station, and positively conveying the medicine plates 4 in the blanking buffer area 6;
S02, after the medicine plate 4 of the blanking buffer area 6 is positively conveyed and is contacted with the swing rod 51, the swing rod 51 is driven to swing forwards;
and S03, when the detection piece detects that the swing rod 51 swings to the preset position, the control unit judges that the number of the medicine plates 4 in the blanking buffer area 6 is within the preset range.
In this embodiment, in step S03, after the number of the medicine plates 4 in the blanking buffer 6 is determined to be within the preset range, the forward transmission of the medicine plates 4 is stopped (i.e., the rear main motor is stopped), and after step S03, the swing link 51 is swung to the initial position to be separated from the medicine plates 4 in the blanking buffer 6, and then the front main motor of the film sealing station and the rear main motor of the blanking discharging station are started, so that the whole machine enters into normal operation.
when the equipment starts to operate, the telescopic rod of the air cylinder rises to enable the swing rod 51 to swing downwards, after the swing rod 51 descends to a proper position, the exhaust valve 55 is opened, compressed air in the air cylinder is released, the air cylinder cannot control the swing rod 51, the swing rod 51 has no driving force, and the swing rod 51 stays below under the action of gravity, namely, a free position. After the exhaust valve 55 is opened, the control unit (PLC controller) reads the current value D0 of the encoder 54 for storage, the current value is D10, then the PLC controller starts the main motor to run at a low speed to drive the buffer zone medicine plates 4 to enter the subsequent blanking station of the device, and the number of the buffer zone medicine plates 4 is continuously reduced. When the number of the buffer area medicine plates 4 is less than a certain number, the buffer area medicine plates 4 drive the swing rod 51 to lift upwards, and the current value D0 of the encoder 54 at the end of the rotating shaft 56 of the swing rod 51 changes continuously. When the difference between the current value D0 of the encoder 54 and the read stored value D10 is larger than a set value, namely the swing rod 51 is located at a preset position, the PLC sends a signal to stop the operation of the main motor, the exhaust valve 55 is closed, the air cylinder is reset to enable the swing rod 51 to ascend to the initial height, the PLC sends a state that the quantity of the medicine plates 4 in the buffer area is adjusted, at the moment, the quantity control and adjustment of the medicine plates 4 in the single buffer area are completed, and the operation of the whole machine can be activated.
the above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may be made by those skilled in the art without departing from the principle of the invention.
