[0045] Please refer to Figure 2 and Figure 3 , the intelligent medicine dispensing and sorting line includes an intelligent medicine dispenser 100 and an intelligent sorting line 200;

[0046] The intelligent sorting line 200 is composed of an artificial review subsystem 201 and a medicine bag sorting subsystem 202; the artificial review subsystem 201 includes a ramp conveyor belt 2011, an artificial sorting conveyor belt 2012, a pusher assembly 2013 and a medicine feeding and distributing assembly. Three groups of artificial workstations 203 are symmetrically arranged on the left and right sides of the artificial sorting conveyor belt 2012, and the three groups of artificial workstations 203 are arranged in sequence from front to back; each group of artificial workstations includes two artificial workstations arranged left and right, and a pusher assembly 2013 is arranged on each artificial workstation. In this way, the number of pusher assemblies 2013 is six; three medicine feeding and distributing assemblies are arranged in sequence from front to back on the artificial sorting conveyor belt 2012, and each medicine feeding and distributing assembly corresponds to a group of artificial workstations.

[0047] The medicine bag sorting subsystem 202 includes a medicine bag conveyor belt 2021 and a medicine discharging and distributing assembly 2022. The ramp conveyor belt 2011, the artificial sorting conveyor belt 2012 and the medicine bag conveyor belt 2021 are connected in sequence to form a medicine bag conveying line. Twelve groups of medicine discharging channels 204 are symmetrically arranged on the left and right sides of the medicine bag conveyor belt 2021, and a medicine discharging and distributing assembly 2022 is arranged between each group of medicine discharging channels 204. The number of medicine discharging and distributing assemblies 2022 is twelve;

[0048] The ramp conveyor belt 2011 is connected to the corresponding intelligent medicine dispenser 100.

[0049] A climbing belt conveyor motor 91 is arranged on the ramp conveyor belt 2011; an artificial sorting belt conveyor motor 92 is arranged on the artificial sorting conveyor belt 2012; a pusher rodless cylinder 94 is arranged on the pusher assembly 2013; a lifting cylinder 95 and a medicine distributing brushless motor 96 are arranged on the medicine feeding and distributing assembly; a sorting servo motor 97 is arranged on each medicine discharging and distributing assembly 2022.

[0050] A light curtain sensor 81 and a photoelectric sensor 82 for detecting the presence or absence of medicine bags are arranged on each pusher assembly 2013; three photoelectric sensors for detecting the position of the artificial sorting belt are respectively arranged on the artificial sorting conveyor belt 2012; three photoelectric sensors for detecting the position of the medicine bag conveyor belt are respectively arranged on the medicine bag conveyor belt 2021; twenty-four photoelectric sensors 86 for detecting the full position of medicine bags are arranged in the turnover boxes corresponding to the twelve groups of medicine discharging channels respectively; a photoelectric sensor for detecting the servo position of medicine bags is arranged on the medicine discharging and distributing assembly 2022.

[0051] The function of the pusher component is to push the sealed and packaged medicine bags onto the medicine bag conveyor line. The function of the medicine feeding and distributing component is to distribute the medicine boxes conveyed by the manual sorting belt conveyor to the designated manual workstations, and it has a lifting function. The medicine discharging and distributing component realizes the function of sorting medicine bags, moving the medicine bags from the medicine bag conveyor belt onto the designated medicine discharging channels, and the channel direction is perpendicular to the medicine bag conveying direction. The medicine discharging and distributing component has the ability of two-way sorting.

[0052] For the control system of the intelligent medicine dispensing and sorting line of the present invention, the main controller 3 is connected to the intelligent medicine dispensing machine control system 1 in an Ethernet manner through the switch 2, forming a master-slave working mode. The intelligent medicine dispensing machine control system 1 serves as the master control end, sending commands, and the main controller 3 serves as the slave end, executing the commands of the master control end and feeding back the system status information.

[0053] The main controller 3 is equipped with an input port 5 and an output port to realize the acquisition of system input quantities and the control of output quantities. According to the system functions, the input information includes: 1) The position detection photoelectric sensor 83 of the medicine box on the manual sorting belt conveyor, which provides an action trigger for the medicine feeding and distributing component, with a quantity of 3; 2) The photoelectric sensor 82 for detecting the presence or absence of medicine bags, which is used to detect whether the medicine bags are correctly placed on the tray of the pusher component. Combining with the light curtain sensor and the status of the medicine bags on the medicine bag conveyor line, it provides an action trigger for the pusher cylinder in the pusher component. Among them, the number of photoelectric sensors for detecting the presence or absence is 6, and the number of light curtain sensors 81 is 6; 3) The position detection photoelectric sensor 84 of the medicine bag on the medicine bag conveyor line, which provides the position information of the medicine bag on the conveyor belt for the main controller 3, with a quantity of 3; 4) Since the number and size of the medicine boxes in different electronic prescription forms are different, which will lead to differences in the size of the finally sealed medicine bags, the laser sensor (LV-N11P + LV-S62) of Keyence is used as the photoelectric sensor 85 for servo position detection of medicine bags to measure the starting position of the medicine bags and provide accurate position information for the subsequent medicine discharging and distributing unit, with a quantity of 1; 5) The dial plate of the medicine discharging and distributing component dials the medicine bags into the designated medicine discharging channels, and the medicine bags fall into the turnover boxes. When the turnover boxes are already full of medicine bags, the photoelectric sensor 86 for detecting the full position of the medicine bags will send a full signal to remind the operator to handle it manually through voice, with a quantity of 24.

[0054] The power sources in the system include motors and cylinders, and different control methods are adopted according to different control objects. 6 pusher rodless cylinders are used in the pusher component of the intelligent sorting line, and 3 double-acting cylinders are used in the medicine feeding and distributing component. All the cylinders adopt single-acting two-position five-way valve control valves and are controlled through the output points of the output module. For the detailed content, please refer to the pneumatic schematic diagram and the electrical schematic diagram.

[0055] There are three conveyor belt machines in the system, namely the climbing conveyor belt machine, the manual sorting conveyor belt machine, and the medicine bag conveyor belt machine. Among them, the climbing conveyor belt machine and the manual sorting conveyor belt machine are used to convey medicine boxes, and they are driven by the method of frequency converter + asynchronous AC motor, and the start and stop of the conveyor belt machine are controlled through the output port 6 of the main controller 3. The medicine bag conveyor belt machine is used to convey medicine bags. Because it is necessary to accurately obtain the position of the medicine bags on the conveyor line to facilitate the sorting of the medicine dispensing components, the driving method of Panasonic servo driver + Panasonic servo motor is adopted. The control method of the servo driver is pulse + direction, and the pulse and direction signals are provided by the output port 6 of the main controller 3.

[0056] In the medicine feeding and distributing component, a brushless DC reduction motor + synchronous pulley driving method is used to divide the medicine boxes left and right. The brushless DC motor is equipped with its own driver, and only the start and direction signals need to be provided by the output port 6 of the main controller 3.

[0057] The medicine dispensing component not only has a large number, but also has relatively precise requirements for the driving distance of the dial plate. Therefore, it is finally determined to adopt the driving method of servo motor + planetary reducer, and the servo motor and driver of Wuhan Maixin Company are selected, model: EP3E-GL1A8-B0S0PN / 60MSL00630BNA. This product supports PROFINET communication, and the control method adopts PROFINET bus control.

[0058] In summary, the control system of the intelligent medicine dispensing and sorting line of the present invention can respond to the instructions of the intelligent medicine dispenser, collect various sensor information, quickly and accurately drive the power source of the equipment to achieve the predetermined actions, and meet the various functions of the intelligent medicine dispensing and sorting line.
