Description

Technical Field

[0001] This invention relates to the field of electrical control technology, and in particular to an electromagnetic vibrating feeder system and control method for glass factories. Background Technology

[0002] Electromagnetic vibrating feeders are a type of glass raw material feeding equipment used to uniformly or quantitatively supply materials from storage silos or other storage equipment to the furnace feed tank, thereby achieving preheating and melting. They are essential equipment for automated production lines. Electromagnetic vibrating feeders are generally used for loose materials, have a simple structure, are easy to operate, require no lubrication, and consume little power; they can uniformly adjust the feed rate and have been widely used.

[0003] Currently, electromagnetic vibrating feeder manufacturers generally include a control box to perform functions such as "starting, stopping, speed adjustment, and protection" of the electromagnetic vibrating feeder; this eliminates the need for owners to design additional control circuits, making procurement and construction more convenient, worry-free, and labor-saving.

[0004] However, in the existing technology, if the built-in control box is damaged, the operator will lose control of the electromagnetic vibrating feeder, affecting normal feeding. Equipment failure will affect the production of the entire glass factory. Even when the control box is operating normally, the operator can only manually control the electromagnetic vibrating feeder on-site and cannot remotely control it from the central control room. The manufacturer's built-in control box cannot inform the DCS (Distributed Control System) of the feeder's operating status, and there are no high or low material level alarms, which is not conducive to real-time monitoring of the feeder.

[0091] In a preferred embodiment, the first connection point of the changeover switch SA1 is connected to the output terminal of the second circuit breaker QL2, and the third connection point of the changeover switch SA1 is connected to the output terminal of the second circuit breaker QL2.

[0092] The first remote button SF1 is connected to the second connection point of the changeover switch SA1;

[0098] The normally open contact DCS_DO of DO is connected to the fourth connection point of the changeover switch SA1.

[0099] The first normally open contact KA11 of the first relay is connected to the second terminal of the normally open contact DCS_DO of the first relay, and the second terminal of the normally open contact KA11 of the first relay is connected to the second terminal of the second remote button SS1.

[0100] The first relay coil KA1 has its first end connected to the first end of the normally open contact DCS_DO, and its second end connected to the external power supply PS.

[0101] Specifically, the second terminal of the first contactor coil KM1 is connected to the neutral line N of the external power supply PS; the second terminal of the first relay coil KA1 is also connected to the neutral line N of the external power supply PS. By controlling the changeover switch SA1, multiple control modes can be switched arbitrarily, including remote or local, manual or DCS control. High and low material level alarm functions have been added, improving the reliability and safety of the feeder operation, and increasing the number of control options to meet production requirements under various changing working conditions.

[0102] More specifically, by operating the remote and local buttons, the on / off states of the first contactor coil KM1 and the first relay coil KA1 can be controlled, thereby controlling the on / off states of the first normally open contact KM12 of the first contactor and the first normally open contact KA11 of the first relay, and ultimately controlling the on / off state of the normally open contact DCS_DO. This enables remote switching control of the second circuit breaker QL2, improving the flexibility and convenience of the circuit.

[0103] In a preferred embodiment, the level monitoring unit (LMC) includes,

[0104] The second normally open contact KM13 of the first contactor is connected to the output terminal of the second circuit breaker QL2.

[0105] The first operating indicator light HG1 is connected to the second terminal of the second normally open contact KM13 of the first contactor, and the second terminal of the first operating indicator light HG1 is connected to the external power supply PS.

[0106] The second operation indicator light HG1a has its first end connected to the first end of the first operation indicator light HG1, and its second end connected to the external power supply unit PS.

[0107] The normally open contact KA21 of the second relay is connected to the output terminal of the second circuit breaker QL2.

[0108] The first high material level indicator HY1 is connected to the second terminal of the normally open contact KA21 of the second relay, and the second terminal of the first high material level indicator HY1 is connected to the external power supply PS.

[0109] The second high material level indicator HY1a has its first end connected to the first end of the first high material level indicator HY1, and its second end connected to the external power supply PS.

[0112] The second low material level indicator HY2a has its first end connected to the first end of the first low material level indicator HY2, and its second end connected to the external power supply PS.

[0113] Specifically, the second end of the first operating indicator light HG1 is connected to the neutral line N of the external power supply unit PS; the second end of the second operating indicator light HG1a is connected to the neutral line N of the external power supply unit PS; the second end of the first high level indicator light HY1 is connected to the neutral line N of the external power supply unit PS; the second end of the second high level indicator light HY1a is connected to the neutral line N of the external power supply unit PS; the second end of the first low level indicator light HY2 is connected to the neutral line N of the external power supply unit PS; and the second end of the second low level indicator light HY2a is connected to the neutral line N of the external power supply unit PS.

[0114] More specifically, it can monitor material levels in real time, promptly detect and handle abnormal material levels, and ensure the smooth operation of the production process.

[0115] More specifically, by connecting various indicator lights and relays, the material level status can be displayed intuitively, improving operators' understanding and control of the material level situation and reducing production accidents and losses caused by material level issues.

[0116] To be more specific, connecting to an external power supply ensures a stable power supply for the monitoring system, guaranteeing its normal operation.

[0117] In a preferred embodiment, the external power supply unit PS includes a first phase line L1, a second phase line L2, and a third phase line L3 of a three-phase power supply.

[0118] Specifically, the external power supply department (PS) can use the UPS (Uninterruptible Power Supply) cabinet from the automation department as the power supply for the electromagnetic vibrating feeder M1. This is because the electromagnetic vibrating feeder M1 is a crucial electrical device in the glass factory, requiring a highly reliable and stable power supply. The UPS cabinet from the automation department has at least two independent power supplies, equipped with double-switch switches. If any one circuit fails, the power can be switched to the other circuit via the double-switch switch to continue supplying power.

[0119] If both independent power sources fail, the built-in UPS battery can still provide power for more than 30 minutes.

[0120] Specifically, this ensures a stable power supply to the electromagnetic vibrating feeder M1, preventing equipment downtime and production interruptions caused by power fluctuations or outages. This not only improves production efficiency but also reduces losses due to maintenance and downtime.

[0121] More specifically, the UPS's double-switch and the backup power of the battery ensure that power can continue to be supplied in the event of a power failure, increasing the reliability and stability of the equipment and guaranteeing the normal operation of the production line.

[0122] In a preferred embodiment, the first local button SE1a, the second local button SF1a, the second running indicator HG1a, the second high material level indicator HY1a, and the second low material level indicator HY2a are all located on the button box BX1 at the operation site.

[0123] The first end of the first local button SE1a is connected to the second end of the second remote button SS1, and the second end of the first local button SE1a is connected to the first end of the first contactor coil KM1; the first end of the second local button SF1a is connected to the first end of the first remote button SF1, and the second end of the second local button SF1a is connected to the second end of the first remote button SF1.

[0124] Specifically, it allows operators to perform operations and monitoring more conveniently and quickly at the work site. At the same time, concentrating relevant buttons and indicator lights in one location helps reduce operator confusion and the possibility of errors, improving operational accuracy and efficiency.

[0125] In a preferred embodiment, the first remote button SF1 and the second remote button SS1 are located on an external control box ACF1 that is far from the electromagnetic vibrating feeder system.

[0126] Specifically, the electromagnetic vibrating feeder system can be remotely controlled, thereby improving operational convenience and safety. Through these two buttons, operators can control the vibrating equipment from a distance, reducing the risk of contact with the equipment and increasing operational flexibility and ease. It also reduces operator workload and improves work efficiency.

[0127] A control method for an electromagnetic vibrating feeder system used in a glass factory, referring to... Figure 6 Electromagnetic vibrating feeder systems for glass factories include,

[0128] Step S1: The external power supply unit PS provides power to the feeder operation unit FOS;

[0129] Step S2: The feeder control unit FCS remotely monitors the production status of the feeder operation unit FOS and switches the control mode of the electromagnetic vibrating feeder M1 of the feeder operation unit FOS.

[0130] Step S3: The electromagnetic vibrating feeder M1 feeds materials according to the feeding speed.

[0131] Specifically, the present invention also provides a control method for an electromagnetic vibrating feeder system used in a glass factory. Through remote monitoring and control, the production status of the feeder operating unit (FOS) can be understood in real time, and the control mode can be adjusted in a timely manner to improve production efficiency. Feeding can be carried out according to the feeding speed, and the feeding amount can be precisely controlled to ensure a stable and efficient production process.

[0132] The electromagnetic vibrating feeder control method for glass plants provided by this invention improves the reliability and safety of feeder operation by adding high and low material level alarm functions. It also increases the selection of control methods, which not only meets the requirements of glass enterprises for remote control and status monitoring of electromagnetic vibrating feeder M1, but also improves the reliability of feeder operation.

[0133] In a preferred embodiment, referencing Figure 7 Step S2 includes,

[0134] Step S21: Remotely monitor the production status of the feeder operation unit FOS through the material level monitoring unit LMC;

[0135] Step S22: The changeover switch SA1 switches the control mode of the electromagnetic vibrating feeder M1 according to production needs.

[0136] Specifically, it enables remote monitoring and control of the feeder, allowing for timely understanding of production status and adjustment of control modes based on production needs. This improves production efficiency, reduces manual intervention, lowers production costs, and ensures the stability and reliability of the production process. Simultaneously, remote monitoring and control also reduces the risks associated with on-site operation, improving workplace safety.

[0137] In the first embodiment, the operator first closes the circuit breakers QL1 and QL2, so that the feeder operation unit FOS and the feeder control unit FCS are connected to a reliable power supply.

[0138] Secondly, when selecting "manual remote" control, the operator should operate the selector switch SA1, turn the knob to "①--②", and operate the button SF1 / SS1 on the external control box ACF1 located in the central control room to control the start and stop of the feeder.

[0139] Specifically, the first connection point of the changeover switch SA1 is connected to the output terminal of the second circuit breaker QL2, the second connection point of the changeover switch SA1 is connected to the first terminal of the first remote button SF1, the third connection point of the changeover switch SA1 is connected to the output terminal of the second circuit breaker QL2, and the fourth connection point of the changeover switch SA1 is connected to the first terminal of the normally open contact DCS_DO.

[0140] When the first remote button SF1 is pressed, the first contactor coil KM1 is energized, and the first normally open contact KM12 of the first contactor closes, completing the "self-locking". At the same time, the main contact KM11 of the first contactor closes, so the feeder control box ACM1 of the electromagnetic vibrating feeder M1 is energized, and the feeder starts to work.

[0141] When the first contactor coil KM1 is energized, the second normally open contact KM13 of the first contactor closes, the HG1 / HG1a indicator light illuminates, and the first normally open contact KM12 of the first contactor closes, transmitting the signal to the DI board to inform the DCS system that the main circuit has been energized.

[0142] When the second remote button SS1 is pressed, the first contactor coil KM1 is de-energized, the first normally open contact KM12 of the first contactor opens, and the "self-locking circuit" is de-energized. Simultaneously, the main contact KM11 of the first contactor opens, so the feeder control box ACM1 is de-energized, and the feeder stops feeding. When the first contactor coil KM1 is energized, the first normally open contact KM12 of the first contactor closes, and the HG1 / HG1a indicator light goes out.

[0143] Secondly, when "manual local" control is selected, the operator should operate the changeover switch SA1, turn the knob to "①--②", and operate the button SF1a / SE1a on the button box BX1 located on site to control the start and stop of the feeder.

[0144] When the first local button SF1a is pressed, the first contactor coil KM1 is energized, and the first normally open contact KM12 of the first contactor closes, completing the "circuit self-locking".

[0145] At the same time, the main contactor KM11 of the first contactor closes, so the feeder control box ACM1 is energized and the feeder starts to work.

[0146] When the first contactor coil KM1 is energized, the second normally open contact KM13 of the first contactor closes, the HG1 / HG1a indicator light illuminates, and the first normally open contact KM12 of the first contactor closes, transmitting the signal to the DI board to inform the DCS system that the main circuit has been energized.

[0147] When the feeder malfunctions, the emergency stop button, namely the first local button SE1a (pressed but not reset), can be pressed. At this time, the first contactor coil KM1 is de-energized, the first normally open contact KM12 of the first contactor is opened, and the "self-locking circuit" is de-energized.

[0148] At the same time, the main contactor KM11 of the first contactor opens, so the feeder control box ACM1 is de-energized, and the feeder stops feeding. When the coil KM1 of the first contactor is energized, the first normally open contact KM12 of the first contactor closes, and the HG1 / HG1a indicator light goes out.

[0149] Then, when using "DCS remote" control, the operator should operate the selector switch SA1 and turn the knob to "③-④". At this time, the first relay coil KA1 is energized, the normally open contact KA11 of the first relay closes, and the signal is transmitted to the DI board, informing the computer that the feeder can be remotely controlled.

[0150] Then, when the normally open contact DCS_DO closes, the first contactor coil KM1 is energized, and then the main contact KM11 of the first contactor closes, so the feeder control box ACM1 is energized and the feeder starts to work.

[0151] When the first contactor coil KM1 is energized, the second normally open contact KM13 of the first contactor closes, the HG1 / HG1a indicator light illuminates, and the first normally open contact KM12 of the first contactor closes, transmitting the signal to the DI board to inform the DCS system that the main circuit has been energized.

[0152] Specifically, by controlling the on / off states of the first contactor coil KM1 and the first relay coil KA1, the on / off states of the first normally open contact KM12 of the first contactor and the first normally open contact KA11 of the first relay are controlled, ultimately controlling the on / off state of the normally open contact DCS_DO. This enables remote switching control of the second circuit breaker QL2, improving the flexibility and convenience of the circuit.

[0153] Remote monitoring and operation enhance the reliability and safety of the circuit. It also facilitates circuit management and maintenance by maintenance personnel. The combined operation of remote and local buttons allows for flexible control of the circuit, ensuring its normal operation and safety.

[0154] When the normally open contact DCS_DO returns to its normally open state, the circuit is disconnected, the feeder control box ACM1 is de-energized, and the feeder stops feeding; at the same time, the HG1 / HG1a indicator lights go out.

[0155] When the normally open contact of the high-level switch LSH closes, the second relay coil KA2 is energized, and then the normally open contact KA21 of the second relay closes. The signal is transmitted to the DCS system in the central control room for alarm, and the first high-level indicator light HY1 in the central control room lights up, reminding the on-duty personnel in the central control room that the feeder hopper is too full at this time.

[0156] When the normally open contact KA21 of the second relay closes, the second high material level indicator HY1a also lights up, simultaneously alerting on-site personnel that the feeder is full. At this time, the operator can operate the feeder control box ACM1 provided by the manufacturer, which has a "speed adjustment button" on the box to appropriately increase the feeder's feeding speed.

[0157] Finally, when the normally open contact of the low material level switch LSL closes, the coil KA3 of the third relay is energized, and then the normally open contact KA31 of the third relay closes. The signal is transmitted to the DCS system in the central control room for alarm, and the first low material level indicator HY2 in the central control room lights up, reminding the on-duty personnel in the central control room that the material in the feeder hopper is insufficient at this time.

[0158] When the normally open contact KA31 of the third relay closes, the second low material level indicator HY2a also lights up, simultaneously alerting on-site personnel that the material in the feeder's hopper is low. At this time, the operator can operate the feeder control box ACM1 provided by the manufacturer, which has a "speed adjustment button" on the box, to appropriately reduce the feeder's feeding speed. At the same time, the operator should contact the on-duty personnel in the raw material workshop, requesting them to expedite the material delivery to the feeder's hopper.

[0159] Reference Figure 5 The third circuit breaker QL0 and KM1 on the external control box ACF1 are connected to the external feeder control box ACM1, electromagnetic vibrating feeder M1, high level switch LSH, low level switch LSL, push button box BX1, DO board, and DI board to realize remote control of the operation of electromagnetic vibrating feeder M1.

[0160] Specifically, the third circuit breaker QL0 is used to control the power supply of the electromagnetic vibrating feeder M1, KM1 is used to control the start and stop of the electromagnetic vibrating feeder M1, the feeder control box ACM1 is used to monitor and adjust the operating status of the electromagnetic vibrating feeder M1, the high level switch LSH and the low level switch LSL are used to detect the material level in the feeder, the push-button box BX1 is used to manually operate the electromagnetic vibrating feeder M1, the DO board is used for digital output control, and the DI board is used for digital input detection.

[0161] More specifically, through these connections, operators can remotely control the operation of the electromagnetic vibratory feeder M1, enabling monitoring and adjustment of the feeder to ensure its normal operation.

[0162] Specifically, this invention provides an electromagnetic vibrating feeder system for glass factories, which improves the original operation method in three aspects:

[0163] First, add an external control circuit to realize the switching function of "remote / local, manual / DCS control";

[0164] Second, add a "run" and "stop" indicator function to the control circuit for the vibrating feeder motor, display the signal locally, and transmit it to the DCS room remotely;

[0165] Third, the control circuit has been enhanced with a "high and low material level over-limit alarm" function, which displays the signal locally and transmits it to the DCS room.

[0166] More specifically, it meets different production requirements and facilitates production management. It enables real-time remote monitoring of the feeder from the central control room, and the addition of local indication functions allows on-site inspectors to promptly grasp the production status, greatly improving the reliability and flexibility of operation and production.

[0167] In summary, this application provides an electromagnetic vibrating feeder system and control method for glass factories. By adding high and low material level alarm functions, the reliability and safety of the feeder operation are improved. It also increases the selection of control methods, which not only meets the requirements of glass enterprises for remote control and status monitoring of the electromagnetic vibrating feeder M1, but also improves the reliability of the feeder operation.

Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
