Description

Technical Field

[0001] This invention relates to the field of diamond-related technologies, and more specifically, to an automated production system and control method for a diamond sorting machine. Background Technology

[0002] The development of the global economy has driven the prosperity of diamond-related industries, especially with the increasing market demand for diamonds driven by emerging industries such as photovoltaics and electronics. At the same time, various application fields have increasingly stringent requirements for the quality of diamonds. Not only are basic properties such as high hardness and high thermal conductivity required, but also higher standards are set for the uniformity and regularity of their particle size and shape, as well as the content of internal defects and impurities. In order to meet market demands, diamond manufacturers need to continuously improve production efficiency, which places higher demands on the performance and automation level of diamond shaping machines.

[0003] Currently, most diamond processing companies in China use traditional shaping machines that are operated manually on a single machine. This results in problems such as excessive manual intervention, insufficient production efficiency, and high costs, making it difficult to meet market demands. Summary of the Invention

[0004] The purpose of this invention is to provide an automated production system and control method for a selection machine that allows for flexible adjustments to system settings and meets the different selection requirements of enterprises and the production needs of different production lines through the setting of control modules. The same production task only needs to be set once, and the control system operates stably according to the settings, resulting in high production efficiency and low cost.

[0005] The technical solution disclosed in this invention is: An automated production system for a shape sorting machine includes a feeding system, a shape sorting machine, and a receiving system; The discharge port of the feeding system is equipped with a discharge valve controlled by a PLC system; The hopper of the sorting machine is equipped with a bottom material shortage inductive proximity sensor and a top material full inductive proximity sensor controlled by a PLC system, which transmit material shortage signals and material full signals to the PLC system; the discharge port is equipped with a sorting machine collection box discharge valve controlled by a PLC system and a sorting machine collection box full inductive proximity sensor. The material receiving system of the aforementioned material receiving system is equipped with a full-material inductive proximity sensor in the material collection box of the shape sorter, which is controlled by the PLC system. When the material collection box of the shape sorter is full, a full-material signal is sent out, and the discharge valve of the material collection box of the shape sorter is controlled by the PLC system to close or open.

[0006] As a preferred embodiment, at least two shape sorting machines are arranged side by side; the feeding system is installed on the feeding travel track and is controlled by the PLC system to run to the corresponding shape sorting machine; the receiving system is installed on the receiving travel track and is controlled by the PLC system to run to the corresponding shape sorting machine collection box.

[0007] As a preferred embodiment, there are at least four shape sorting machines, two of which are arranged side by side and the other two are respectively arranged at both ends of the feeding system; the feeding system is installed on the feeding travel track and is controlled by the PLC system to run the feeding system to the corresponding shape sorting machine; the receiving system is installed on the receiving travel track and is controlled by the PLC system to run the receiving system to the corresponding shape sorting machine collection box.

[0008] A control method for controlling an automated production system of a shape sorting machine includes: (1) Automatic feeding steps: The bottom material shortage inductive proximity sensor and the top material full inductive proximity sensor collect signals in the hopper of the shape sorter. When there is a material shortage in the hopper, the bottom material shortage inductive proximity sensor triggers low-position sensing and sends an electrical signal to the sub-PLC. The sub-PLC transmits the signal to the main PLC through the network. The main PLC sends a pulse signal to the servo motor of the feeding system. After receiving the pulse signal, the servo motor starts to move the feeding system according to the set number of pulses. After reaching the position, it will internally transmit a pulse completion signal to the main PLC. After receiving the internal completion signal, the main PLC will send an electrical signal to the discharge valve of the feeding system, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material in the hopper of the feeding system flows to the hopper of the shape sorter through the pipe and valve, realizing the feeding function. During the feeding process, the material height in the hopper of the shape sorter gradually rises. When the material height reaches the full material sensing position of the top full material inductive proximity sensor, a full material signal is triggered and an electrical signal is sent to the main PLC. The main PLC sends an electrical signal to the discharge valve of the feeding system, causing the electric push rod of the discharge valve of the feeding system to close the valve, thus completing one feeding cycle. After the entire process is completed, the main PLC counts the material feeding once. When the material receiving count reaches the set parameter, the main PLC alarms and prompts the user to add material to the hopper of the feeding system. (2) Automatic material clearing steps: The signal of the full material inductive proximity sensor is collected and the full material signal is transmitted to the main PLC via the sub-PLC. The sub-PLC transmits the signal to the main PLC of the central control console via the network. The main PLC sends a pulse signal to the servo motor of the material receiving system. After receiving the pulse signal, the servo motor starts to move the material receiving system according to the set number of pulses. After moving to the position, it will internally transmit a pulse completion signal to the sub-PLC. After receiving the internal completion signal, the sub-PLC will send an electrical signal to the discharge valve of the collection box, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material inside the material collection box and the transmission pipeline of the sorting machine will be discharged, realizing the material clearing function. During the cleaning process, the material height in the collection box gradually decreases. When the material is lower than the high-level sensor, the full material signal is eliminated. At this time, the sub-PLC starts timing. When the timing ends, the sub-PLC sends an electrical signal to the discharge valve of the collection box, causing the electric push rod of the discharge valve to close the valve, completing one cleaning cycle. After the entire process is completed, the main PLC counts the material received once. When the material received count reaches the set parameter, the main PLC alarms, prompting the user to clean the material box of the receiving system.

[0009] As a preferred option, an automatic feeding fault control step is also included in the automatic feeding process: if the feeding system malfunctions due to a sensor or system failure, resulting in the inability to stop feeding in time and causing overflow, a timer program is added to the main program: when the discharge valve of the forming machine feeding system opens, the main PLC starts timing. After the timing ends, the main PLC alarm is triggered, and at the same time, the main PLC sends an electrical signal to the discharge valve of the feeding system to close the valve, forcibly ending the feeding. Feeding resumes after the user troubleshoots the fault and manually clears the alarm. When setting this timing, the timing time is slightly longer than the time of one complete feeding process of the main program.

[0010] As a preferred option, an automatic material collection failure control step is also included in the automatic material clearing process: if the material collection system malfunctions due to mechanical or system failure, resulting in the inability to clear the material inside the sorting machine's collection box in time and causing overflow, a timer program is added to the main program: when the high-position sensing of the inductive proximity sensor of the sorting machine's collection box is triggered, the sub-PLC starts timing. After the timing ends, the sub-PLC alarm is triggered, and at the same time, the sub-PLC shuts down the power supply of the sorting machine feeder through Modbus communication, forcibly interrupting the sorting process. Production resumes after the user troubleshoots the fault and manually clears the alarm. When setting this timer, it is slightly longer than the time of one complete material collection process in the main program.

[0011] As a preferred option, after the entire automatic feeding process is completed, the main PLC counts the feeding once. When the count reaches the set parameter, the main PLC alarms and prompts the user to add material to hopper 1 of the feeding system.

[0012] As a preferred solution, the automatic feeding process is configured such that after the feeding system's discharge valve opens and the set time has elapsed, if the main PLC has not received a signal from the full-material inductive proximity sensor at the top of the hopper of the shape selector, an alarm is triggered to prompt the user to check for abnormalities and to add material to the hopper of the feeding system.

[0013] The beneficial effects of this invention are: 1. The system settings are flexible and can be adjusted to meet the different selection requirements of enterprises and the production needs of different production lines through the settings of the control module. The same production task only needs to be set once, and the control system will operate stably according to the settings. 2. The robot's operation mainly relies on robotic arms, solenoid valves, and a control system, with a streamlined operating system. It also moves flexibly through aisles, does not occupy production space, and has strong site adaptability. 3. The automation control module and the production module are independent of each other. If the automatic control system malfunctions and cannot be resolved in time, other robots can be arranged to replace it or manual operation can be carried out without affecting the normal production of the mother machine. 4. The control system uses advanced algorithms and logic to coordinate the operation of various intelligent feeding and receiving devices, monitors the production status in real time, and ensures efficient, continuous and stable production, enabling unmanned production.

[0020] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 , Figure 2 and Figure 3 The production system of the present invention includes a feeding system A, a shaping machine B, and a receiving system C; The discharge port of the feeding system 1 is equipped with a feeding system discharge valve 2 controlled by a PLC system; The hopper 4 of the sorting machine B is equipped with a bottom material shortage inductive proximity sensor 10 and a top material full inductive proximity sensor 11 controlled by a PLC system, which transmit material shortage signals and material full signals to the PLC system; the discharge port is equipped with a sorting machine collection box discharge valve 6 and a sorting machine collection box full inductive proximity sensor 12 controlled by a PLC system. The material receiving system C is equipped with a full material inductive proximity sensor 12 in the material receiving box 7 of the shape sorting machine, which is controlled by the PLC system. When the material receiving box 5 of the shape sorting machine is full, a full material signal is sent out, and the discharge valve 6 of the material receiving box of the shape sorting machine is closed by the PLC system.

[0021] At least two shape sorting machines B are arranged side by side; the feeding system A is installed on the feeding travel track and is controlled by the PLC system to run to the corresponding shape sorting machine B; the receiving system C is installed on the receiving travel track and is controlled by the PLC system to run to the corresponding shape sorting machine collection box 5.

[0022] There are at least four shape sorting machines B, two of which are arranged side by side and the other two are respectively arranged at both ends of the feeding system A; the feeding system A is installed on the feeding travel track and is controlled by the PLC system to run to the corresponding shape sorting machine B; the receiving system C is installed on the receiving travel track and is controlled by the PLC system to run to the corresponding shape sorting machine collection box 5.

[0023] The shape selector of the present invention can be arranged side by side or in two rows at both ends of the feeding system A, depending on the application scenario.

[0024] Figure 1 The embodiment shown uses two shape selectors B arranged at both ends of the feeding system A.

[0025] Figure 2 and Figure 3 The embodiment shown uses a structure with five shape selectors B arranged side by side.

[0026] right Figure 1 , Figure 2 , Figure 3 The methods for controlling the structure shown include: (1) Automatic feeding steps: Please refer to Figure 4 The bottom material shortage inductive proximity sensor 10 and the top material full inductive proximity sensor 11 in the hopper 4 of the sorting machine collect signals. When there is a material shortage in the hopper, the bottom material shortage inductive proximity sensor 10 triggers low-level sensing and sends an electrical signal to the sub-PLC. The sub-PLC transmits the signal to the main PLC via the network. The main PLC sends a pulse signal to the servo motor 3 of the feeding system. After receiving the pulse signal, the servo motor starts to move the feeding system according to the set number of pulses. After reaching the position, it internally transmits a pulse completion signal to the main PLC. After receiving the internal completion signal, the main PLC sends an electrical signal to the discharge valve 2 of the feeding system, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material in the hopper 1 of the feeding system flows to the hopper of the sorting machine through the pipe and valve, realizing the feeding function. During the feeding process, the material height in the hopper 4 of the shape sorter gradually rises. When the material height reaches the full material sensing position of the top full material inductive proximity sensor 11, a full material signal is triggered and an electrical signal is sent to the main PLC. The main PLC sends an electrical signal to the discharge valve 2 of the feeding system, causing the electric push rod of the discharge valve of the feeding system to close the valve, thus completing one feeding cycle. After the entire process is completed, the main PLC counts the material feeding once. When the material receiving count reaches the set parameter, the main PLC alarms, prompting the user to add material to hopper 1 of the feeding system. In the automatic feeding step, it is set that if the main PLC has not received the signal from the inductive proximity sensor 11 at the top of the hopper 4 of the shape selector after the feeding system discharge valve 2 has been opened and the set parameter has been reached, the main PLC will also trigger an alarm, prompting the user to check for abnormalities and add material to hopper 1 of the feeding system.

[0027] (2) Automatic material cleaning steps: Please refer to Figure 5 The system collects the signal from the full-material inductive proximity sensor 12, transmits the full-material signal to the main PLC via the sub-PLC, and then transmits it to the main PLC of the central control console via the network. The main PLC sends a pulse signal to the servo motor 8 of the receiving system. After receiving the pulse signal, the servo motor starts to move the receiving system according to the set number of pulses. After reaching the position, it internally transmits a pulse completion signal to the sub-PLC. After receiving the internal completion signal, the sub-PLC sends an electrical signal to the discharge valve 6 of the collection box, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material inside the material collection box and the transmission pipeline of the sorting machine begins to be discharged, realizing the cleaning function. During the material clearing process, the material height in the material box gradually decreases. When the material is lower than the high-level sensor, the full material signal is eliminated. At this time, the sub-PLC starts timing. When the timing ends, the sub-PLC sends an electrical signal to the material collection box discharge valve 6, causing the electric push rod of the discharge valve to close the valve, completing one clearing cycle. After the entire process is completed, the main PLC counts the material collection once. When the material collection count reaches the set parameter, the main PLC alarms, prompting the user to clean the material collection system's material box 7.

[0028] The automatic feeding process also includes an automatic control step for feeding failures: if a feeding system malfunctions due to a sensor or system failure, resulting in the inability to stop feeding in time and causing overflow, a timer program is added to the main program: when the discharge valve 2 of the forming machine feeding system opens, the main PLC starts timing. After the timing ends, the main PLC alarm is triggered, and at the same time, the main PLC sends an electrical signal to the discharge valve 2 of the feeding system to close the valve, forcibly ending the feeding. Feeding resumes after the user troubleshoots the fault and manually clears the alarm. When setting this timing, the timing time is slightly longer than the time of one complete feeding process of the main program.

[0029] In the automatic material clearing step, an automatic control step for material collection failure is also set up: if the material collection system fails due to mechanical or system failure, resulting in the inability to clear the material inside the material collection box of the sorting machine in time and causing overflow, a timer program is added to the main program: when the high-position sensing of the inductive proximity sensor 12 of the material collection box 5 of the sorting machine is triggered, the sub-PLC starts timing. After the timing ends, the sub-PLC alarm is triggered. At the same time, the sub-PLC shuts down the power of the feeder 9 of the sorting machine through Modbus communication, forcibly interrupting the sorting. Production resumes after the user troubleshoots the fault and manually clears the alarm. When setting it, this timing time is slightly longer than the time of one complete material collection process of the main program.

[0030] The following is a working process of this embodiment: When the power is turned on, the feeding system A, the shape sorter B, and the receiving system C start working. The material enters the shape sorter hopper 4 from the discharge valve 2 of the feeding system. The material after shape sorting enters the different shape sorter collection boxes 5 according to the degree of sphericity.

[0031] The bottom and top of the sorting machine hopper 4 are respectively equipped with a material shortage inductive proximity sensor 10 and a full material inductive proximity sensor 11. When there is a material shortage in the hopper (the material position is lower than the bottom sensor), the low-position sensing is triggered, and an electrical signal is sent to the sub-PLC inside the sorting machine. The sub-PLC transmits the signal to the main PLC of the central control console via the network. The main PLC sends a pulse signal to the servo motor 3 of the feeding system. After receiving the pulse signal, the servo motor starts to move the feeding system A according to the set number of pulses. After reaching the position, it internally transmits a pulse completion signal to the main PLC. After receiving the internal completion signal, the main PLC sends an electrical signal to the discharge valve 2 of the feeding system, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material in the feeding system hopper 1 flows to the sorting machine hopper through the pipe and valve, realizing the feeding function.

[0032] During the feeding process, the material height in the hopper 4 of the shape sorter gradually rises. When the material height reaches the full material sensing position, a full material signal is triggered and an electrical signal is sent to the main PLC. The main PLC sends an electrical signal to the discharge valve 2 of the feeding system, causing the electric push rod of the discharge valve of the feeding system to close the valve, thus completing one feeding cycle.

[0033] After the entire process is completed, the main PLC counts the material feeding once. When the material receiving count reaches the set parameter, the main PLC alarms and prompts the user to add material to hopper 1 of the feeding system.

[0034] To prevent overflow caused by feeding system malfunctions due to sensor failures or system faults, a timer program has been added to the main program: when the discharge valve 2 of the forming machine's feeding system opens, the main PLC starts a timer. After the timer expires, an alarm is triggered on the main PLC, and simultaneously, the main PLC sends an electrical signal to the discharge valve 2 of the feeding system to close the valve, forcibly ending the feeding. Feeding resumes after the user manually clears the alarm after troubleshooting. This timer is set to be slightly longer than the time of one complete feeding cycle in the main program.

[0035] A full-material inductive proximity sensor 12 is installed on the top of the material collection box 5 of the sorting machine. When the material collection box is full, it triggers a high-level sensor, which sends an electrical signal to the sub-PLC inside the sorting machine. The sub-PLC transmits the signal to the main PLC on the central control console via the network. The main PLC sends a pulse signal to the servo motor 8 of the receiving system. After receiving the pulse signal, the servo motor starts moving the receiving system according to the set number of pulses. After reaching the position, it internally transmits a pulse completion signal to the sub-PLC. After receiving the internal completion signal, the sub-PLC sends an electrical signal to the discharge valve 6 of the material collection box, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material inside the material collection box and the transmission pipeline of the sorting machine begins to be discharged, realizing the cleaning function.

[0036] During the cleaning process, the material height in the collection box gradually decreases. When the material is lower than the high position sensor, the full material signal is eliminated. At this time, the sub-PLC starts timing. When the timing ends, the sub-PLC sends an electrical signal to the discharge valve 6 of the collection box, causing the electric push rod of the discharge valve to close the valve, thus completing one cleaning cycle.

[0037] After the entire process is completed, the main PLC counts the material receiving once. When the material receiving count reaches the set parameter, the main PLC alarms, prompting the user to clean the material receiving system's material box 7.

[0038] To prevent material overflow from the sorting machine's collection box due to mechanical or system malfunctions causing the material receiving system to fail and thus overflow, a timer program has been added to the main program: when the full material sensor 12 of the sorting machine's collection box 5 is triggered, the sub-PLC starts timing. After the timer expires, the sub-PLC alarms and simultaneously shuts off the power to the sorting machine's feeder 9 via Modbus communication, forcibly interrupting the sorting process. Production resumes after the user manually clears the alarm after troubleshooting. When setting this timer, it is set to be slightly longer than the time of one complete material receiving cycle in the main program.

[0039] In this embodiment, a sorting machine is equipped with five sorting machine collection boxes (in actual applications, each sorting machine can be equipped with 1-15 collection boxes, which can be designed according to the user's production needs). The position of the discharge valve of each sorting machine collection box is set with a predetermined pulse signal. When any sorting machine collection box is full, a high-level sensor is triggered, and the signal is transmitted to the sub-PLC inside the sorting machine. The sub-PLC transmits the signal to the main PLC of the central control console via the network. The main PLC sends a pulse signal to the servo motor 3 of the feeding system. After receiving the pulse signal, the servo motor starts to move the feeding system A according to the set number of pulses. After reaching the position, it internally transmits a pulse completion signal to the sub-PLC. After receiving the internal completion signal, the sub-PLC sends an electrical signal to the discharge valve 6 of the collection box, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material inside the sorting machine collection box and the transmission pipeline begins to be discharged, realizing the cleaning function.

[0040] Similarly, in Figure 2 , 3In the structure shown, a set pulse signal is set for the position of each hopper 4 of the sorting machine. When any hopper 4 of the sorting machine is short of material, a set pulse signal is sent to the sub-PLC. The sub-PLC transmits the signal to the main PLC via the network. The main PLC sends a pulse signal to the servo motor 3 of the feeding system. After receiving the pulse signal, the servo motor starts to move the feeding system according to the set number of pulses until it reaches the position. After reaching the position, it internally transmits a pulse completion signal to the main PLC. After receiving the internal completion signal, the main PLC sends an electrical signal to the discharge valve 2 of the feeding system, causing the electric push rod of the discharge valve to open the valve. Under the action of gravity, the material in the hopper 1 of the feeding system flows to the hopper of the sorting machine through the pipe and valve, realizing the feeding function.

[0041] In practical applications, the shape sorting machine can adopt... Figure 2 , Figure 3 The structure shown, with a single row distributed on one side of the feeding system A, can also be adopted. Figure 1 The structure shown is a double-row distribution at both ends of the feeding system A.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
