Description

Technical Field

[0001] The present disclosure relates to the field of glass production, and in particular to an emergency disposal system for ultra-thin glass production and molding. Background Art

[0002] When producing ultra-thin glass, the forming process is the process of converting the glass from a flowing liquid to a solid glass ribbon. According to the production sequence from high temperature to low temperature, the required equipment is a high temperature furnace, a medium temperature furnace, a low temperature furnace, and a traction device. In order to reduce the influence of glass gravity on the glass ribbon, each device is arranged vertically. In the high temperature furnace, the thickness of the glass ribbon is slightly adjusted. In the medium temperature furnace, the consistency of the thickness of the glass ribbon is further optimized, and then the shape is fixed by extreme cold, which is referred to as the finalization stage. In the low temperature furnace, the glass ribbon continues to cool down, and according to the characteristics of the glass, the internal stress of the glass is removed, that is, the annealing stage. The traction equipment is composed of a pair of traction rollers with a certain hardness. Through the lever action, the rollers provide the clamping force of the glass ribbon, and the servo motor drives to ensure that the speed of the paired traction rollers is consistent. Since the glass flows by its own gravity, the thickness does not meet the ultra-thin glass standard. Therefore, it is necessary to increase the linear speed of the traction equipment rollers to be greater than the glass's own gravity flow speed, and pull the glass ribbon to the required target thickness while the glass shape changes in the medium temperature furnace. The power adjustment and speed adjustment of the equipment are all realized through the DCS system in the control room. In the molding process, many abnormal situations may occur. If not handled in time, it will cause the liquid glass to flow poorly or not flow, causing serious damage to the production equipment.

[0003] Due to the transformation process of glass form and the high-speed traction of the traction equipment, the glass ribbon is too thin, so the process control deviation or other conditions will cause the glass ribbon to break above the traction equipment, which is called a broken plate. When the plate breaks, due to the disappearance of the high-speed traction of the traction equipment, the flow speed of the glass ribbon itself is too low, and the surface tension of the glass will cause the glass liquid to change into a spherical shape, which will be blocked at the outlet of the high-temperature furnace and the upper part of the medium-temperature furnace, causing the glass in the high-temperature furnace to be unable to flow down, thereby damaging the equipment.

[0004] Related technology CN 204883315 U discloses an ultra-thin glass break monitoring device, including an infrared thermometer group, which is connected to a PLC controller arranged in a control room through a circuit, and the PLC controller is connected to an alarm arranged in a monitoring room; the infrared thermometer group is divided into three groups, which are arranged above the tin bath outlet area, above the main drive roller area, and above the annealing area. By assembling three electrical devices, an infrared thermometer, a PLC controller, and an alarm, timely and effective monitoring of the glass plate can be achieved; the PLC controller is connected to a servo motor, and when a glass break is detected, the rotation speed of the edge drawing wheel and the main drive roller controlled by the servo motor is reduced accordingly, thereby providing sufficient time for the staff to handle it in time. However, the staff is required to handle the broken glass, and the fully automatic processing of the broken plate cannot be achieved, which poses certain personnel safety hazards.

[0005] Based on this, there is room for improvement in the monitoring of broken panels and emergency operations in the ultra-thin glass forming process. Utility Model Content

[0035] Compared with the molding process equipment in the ultra-thin glass production in the prior art, the ultra-thin glass production molding emergency disposal system disclosed in the present invention detects the glass ribbon 6 through the sensor 7 on the traction device 4 and the first camera 501 on the medium temperature furnace 2 and the second camera 502 on the low temperature furnace 3, and determines whether there is a broken plate through the DCS system. In the case of a broken plate, the temperature of the glass ribbon 6 is adjusted by controlling the temperature of the high temperature furnace 1, the medium temperature furnace 2, and the low temperature furnace 3 through the DCS system, and the opening or clamping of the traction roller 41 of the traction device 4 is controlled through the DCS system, so as to promptly handle the broken plate situation and resume production.

[0036] In some embodiments, the high temperature furnace 1 includes a high temperature furnace shell 101, a high temperature furnace heater 102 and a high temperature furnace observation window 103. The high temperature furnace heater 102 is arranged on the high temperature furnace shell 101. The high temperature furnace observation window 103 is symmetrically arranged on two opposite sides of the high temperature furnace shell 101 that are perpendicular to the length direction of the first opening. The high temperature furnace heater 102 is connected to the DCS system for communication and is controlled by the DCS system. This design ensures that the heating of the high temperature furnace 1 can be controlled by the DCS system and the glass ribbon 6 in the high temperature furnace 1 can be observed through the high temperature furnace observation window 103.

[0037] In some embodiments, the medium temperature furnace 2 includes a medium temperature furnace shell 201, a medium temperature furnace heater 202 and a medium temperature furnace observation window 203. The medium temperature furnace heater 202 is arranged on the medium temperature furnace shell 201. The medium temperature furnace observation window 203 is symmetrically arranged on two opposite sides of the medium temperature furnace shell 201 that are perpendicular to the length direction of the second opening. The medium temperature furnace heater 202 is connected to the DCS system for communication and is controlled by the DCS system. This design ensures that the heating of the medium temperature furnace 2 can be controlled by the DCS system and the glass ribbon 6 in the medium temperature furnace 2 can be observed through the medium temperature furnace observation window 203.

[0038] In some embodiments, a first camera 501 is disposed outside the medium temperature furnace observation window 203. The first camera 501 is used to detect the glass ribbon 6 in the medium temperature furnace 2. The first camera 501 is connected to the DCS system for communication and transmits the detection signal of the glass ribbon 6 to the DCS system. This design ensures that the DCS system obtains the detection signal of the first camera 501 in real time and determines whether there is a glass ribbon 6 passing through the medium temperature furnace 2.

[0039] In some embodiments, the low temperature furnace 3 includes a low temperature furnace shell 301, a low temperature furnace heater 302 and a low temperature furnace observation window 303. The low temperature furnace heater 302 is arranged on the low temperature furnace shell 301. The low temperature furnace observation window 303 is symmetrically arranged on two opposite sides of the low temperature furnace shell 301 that are perpendicular to the length direction of the third opening. The low temperature furnace heater 302 is connected to the DCS system for communication and is controlled by the DCS system. This design ensures that the heating of the low temperature furnace 3 can be controlled by the DCS system and the glass ribbon 6 in the low temperature furnace 3 can be observed through the low temperature furnace observation window 303.

[0040] In some embodiments, a second camera 502 is disposed outside the low-temperature furnace observation window 303. The second camera 502 is used to detect the glass ribbon 6 in the low-temperature furnace 3. The second camera 502 is connected to the DCS system for communication and transmits the detection signal of the glass ribbon 6 to the DCS system. This design ensures that the DCS system obtains the detection signal of the second camera 502 in real time and determines whether there is a glass ribbon 6 passing through the low-temperature furnace 3.

[0041] In some embodiments, the traction roller 41 includes a traction roller wheel 401, a traction roller shaft 402, and a driving device 403. The traction roller wheel 401 is arranged on the traction roller shaft 402 and is used to contact and pull the glass ribbon 6. One end of the traction roller shaft 402 is connected to the driving device 403. The driving device 403 drives the traction roller shaft 402 to rotate, and then the traction roller shaft 402 drives the traction roller wheel 401 to rotate. The driving device 403 is connected to the DCS system and is controlled by the DCS system. This design ensures that the traction device 4 can thin the glass ribbon 6.

[0042] In some embodiments, the sensor 7 is disposed above the traction roller 401, the sensor 7 faces the glass ribbon 6, and the sensor 7 is used to detect the glass ribbon 6 passing through the traction roller 401. The sensor 7 is connected to the DCS system for communication and transmits the detection signal of the glass ribbon 6 to the DCS system. This design ensures that the DCS system obtains the detection signal of the sensor 7 in real time and determines whether the glass ribbon 6 passes through the traction roller 401.

[0043] In some embodiments, when the first camera 501, the second camera 502 and the sensor 7 detect the glass ribbon 6, if the glass ribbon 6 is not detected for more than a set time, the first camera 501, the second camera 502 and the sensor 7 transmit the detection signal to the DCS system for judgment. For example, the set time may be 5 seconds. This design ensures effective transmission of the detection signal and avoids misjudgment.

[0044] In some embodiments, the emergency disposal system for ultra-thin glass production and molding includes an alarm device (not shown), and the sensor 7 is connected to the alarm device. The alarm device can perform sound and light alarms. This design ensures that the staff on duty can be warned.

[0045] In some embodiments, two traction rollers 401 are disposed on the traction roller shaft 402, and the two traction rollers 401 are fixed on the traction roller shaft 402 corresponding to the two sides of the glass ribbon 6, so that the two sides of the glass ribbon 6 are evenly acted upon by the traction rollers 401. This design ensures that the traction roller shaft 402 drives the two traction rollers 401 to generate the same force on the glass ribbon 6 at the same time.

[0046] In some embodiments, the paired traction rollers 41 are located on both sides of the glass ribbon 6 and the planes where the axes of the respective traction roller shafts 402 of the paired traction rollers 41 are located are perpendicular to the glass ribbon 6. When the traction device 4 works normally, the two traction roller shafts 402 of the paired traction rollers 41 are at equal distances from the glass ribbon 6. This design ensures that the traction roller wheels 401 on the traction roller shafts 402 of the paired traction rollers 41 exert a clamping force on the glass ribbon 6 through a lever action, and that the glass ribbon 6 passes vertically through the paired traction rollers 41.

[0047] In some embodiments, the traction device 4 includes three pairs of traction rollers 41, which are arranged in sequence from top to bottom in the vertical direction. The two traction roller shafts 402 of the three pairs of traction rollers 41 are respectively arranged on both sides of the glass ribbon 6, and the planes where the axes of the two traction roller shafts 402 are located are perpendicular to the glass ribbon 6. When the traction device 4 works normally, the distances between the two traction roller shafts 402 of the three pairs of traction rollers 41 and the glass ribbon 6 are equal. The first sensor 701, the second sensor 702, and the third sensor 703 are respectively arranged above the traction roller shafts 402 of the three pairs of traction rollers 41 on the same side of the glass ribbon 6. This design ensures that the traction roller wheels 401 on the traction roller shafts 402 of the three pairs of traction rollers 41 clamp the glass ribbon 6 through the lever action, and that the glass ribbon 6 passes vertically through the three pairs of traction rollers 41.

[0048] In some embodiments, the driving device 403 of the traction roller 41 includes a servo motor, the shaft of the servo motor is fixedly connected to the traction roller shaft 402, and the servo motor is in communication connection with the DCS system, so that the servo motor is controlled by the DCS system to drive the traction roller shaft 402 to drive the traction roller 401 to rotate. This design ensures that the linear speed of the traction roller 401 controlled by the DCS system is greater than the gravity flow speed of the glass itself.

[0049] In some embodiments, the respective traction roller shafts 402 of the pair of traction rollers 41 rotate around their respective axes in opposite directions but at the same speed, so the respective traction roller wheels 401 of the pair of traction rollers 41 rotate in opposite directions and pull the glass ribbon 6 downward. This design ensures that the glass ribbon 6 passes through the traction device 4 at a uniform speed.

[0050] In some embodiments, the traction device 4 includes a cylinder (not shown), which is connected to a support seat (not shown) of the traction roller shaft 402, and the cylinder is connected to the DCS system for communication and is controlled by the DCS system. The cylinder is used to drive the support seat to move in a direction perpendicular to the glass ribbon 6, thereby driving the traction roller shaft 402 to move close to or away from the glass ribbon 6. This design ensures the opening or clamping of the two traction rollers 41 of the pair of traction rollers 41, that is, the two traction rollers 41 of the pair of traction rollers 41 are ensured to be in an open position and a clamping position. When the two traction rollers 41 of the pair of traction rollers 41 are in the open position, the respective traction roller shafts 402 of the two traction rollers 41 are in a position away from the glass ribbon 6, and when the two traction rollers 41 of the pair of traction rollers 41 are in the clamping position, the respective traction roller shafts 402 of the two traction rollers 41 are close to the glass ribbon 6 and clamp the glass ribbon 6, thereby achieving the release of the glass ribbon 6 between the respective traction roller wheels 401 of the pair of traction rollers 41 and the clamping of the glass ribbon 6 between the respective traction roller wheels 401 of the pair of traction rollers 41.

[0051] In some embodiments, the DCS system is configured to control the cylinder through a solenoid valve (not shown) so that the cylinder drives the traction roller shaft 402 to move away from or close to the glass ribbon 6, thereby opening or clamping the two traction rollers 41 of the pair of traction rollers 41.

[0052] In some embodiments, the DCS system is configured to receive the detection signals transmitted by the first camera 501, the second camera 502 and the sensor 7 respectively and determine whether there is a glass ribbon 6. The DCS system is also configured to control the heating of the high temperature furnace 1, the medium temperature furnace 2 and the low temperature furnace 3 and control the opening or clamping of the pair of traction rollers 41 of the traction device 4. This design ensures that the emergency disposal system for ultra-thin glass production and molding can automatically detect the glass ribbon 6, automatically adjust the temperature of the glass ribbon 6 and automatically handle broken glass.

[0053] like Figure 3 As shown, the emergency treatment of the emergency disposal system for ultra-thin glass production and molding includes: when the sensor 7 detects that there is no glass ribbon 6 at the paired traction rollers 41, the detection signal is transmitted to the DCS system and the alarm device, the DCS system starts the power adjustment of the high temperature furnace heater 102, the medium temperature furnace heater 202, and the low temperature furnace heater 302 and opens the paired traction rollers 41, and the alarm device turns on the sound and light alarm at the same time, and the staff on duty handles it on site. After the processing is completed, the alarm is lifted and production is resumed.

[0054] In some embodiments, when the board is broken, the power adjustment of the medium temperature furnace 2 and the low temperature furnace 3 includes a slope adjustment method and an immediate adjustment method. The slope adjustment method is to set the target power and the time to reach the target power, and reach the target power according to a certain power increase rate. The immediate adjustment method is to reach the target power immediately, and the time required in the middle is the shortest time required for the heating element power to increase or decrease. In the case of a broken board, the immediate adjustment method is usually adopted, that is, the power is first increased to the set value. This design reduces the time for heat generation and transfer.

[0055] After the glass ribbon 6 breaks, it is necessary to open the paired traction rollers 41 of the traction device 4 and increase the heating power of the medium temperature furnace 2 and the low temperature furnace 3. The purpose is to increase the temperature of the glass ribbon 6, reduce the viscosity of the glass ribbon 6, increase the flow rate, and realize the automatic downflow of the glass ribbon 6 as soon as possible. When the glass ribbon 6 reaches the position of the traction device 4, the paired traction rollers 41 clamp the glass ribbon 6, and gradually increase the linear speed of the traction roller 401 to gradually thin the glass ribbon 6 in the medium temperature furnace 2 to the target thickness.

[0056] like Figure 1 and 2As shown, the emergency disposal system for ultra-thin glass production and molding disclosed in the present invention comprises a high-temperature furnace 1, a medium-temperature furnace 2, a low-temperature furnace 3, a traction device 4, a DCS system, two first cameras 501, two second cameras 502 and three sensors 7. The high-temperature furnace 1, the medium-temperature furnace 2, the low-temperature furnace 3 and the three pairs of traction rollers 41 of the traction device 4 are arranged in sequence from top to bottom in the vertical direction, and the first opening of the high-temperature furnace 1, the second opening of the medium-temperature furnace 2 and the third opening of the low-temperature furnace 3 are aligned with the respective gaps of the three pairs of traction rollers 41 of the traction device 4, so that the glass ribbon 6 moves in the vertical direction. The high-temperature furnace heater 102 of the high-temperature furnace 1, the medium-temperature furnace heater 202 of the medium-temperature furnace 2, the low-temperature furnace heater 302 of the low-temperature furnace 3, the driving device 403 of the traction roller 41 and the cylinder of the traction device 4 are respectively connected to the DCS system for communication and controlled by the DCS system. The two first cameras 501 are respectively arranged on the outside of the medium temperature furnace observation window 203 on both sides of the medium temperature furnace 2, the two second cameras 502 are respectively arranged on the outside of the low temperature furnace observation window 303 on both sides of the low temperature furnace 3, the two traction roller shafts 402 of the three pairs of traction rollers 41 are respectively arranged on both sides of the glass ribbon 6, and the plane where the axes of the two traction roller shafts 402 are located is perpendicular to the glass ribbon 6, and two traction roller wheels 401 are arranged on each traction roller shaft 402, the first sensor 701, the second sensor 702, and the third sensor 703 are respectively arranged above the traction roller shafts 402 of the three pairs of traction rollers 41 on the same side of the glass ribbon 6 from top to bottom in the vertical direction, the two first cameras 501, the two second cameras 502 and the first sensor 701, the second sensor 702, and the third sensor 703 are respectively connected to the DCS system for communication and transmit the detection signals to the DCS system respectively, and the first sensor 701, the second sensor 702, and the third sensor 703 are respectively connected to the alarm device for communication and can send signals to the alarm device to start the alarm device to alarm.

[0057] When the emergency disposal system for ultra-thin glass production and molding disclosed in the present invention is used, the thickness of the glass ribbon 6 is slightly adjusted in the high-temperature furnace 1; the glass ribbon 6 is shaped in the medium-temperature furnace 2, and the first camera 501 detects the glass ribbon 6 in the medium-temperature furnace 2 and transmits the detection signal to the DCS system; the glass ribbon 6 is annealed and stress-relieved in the low-temperature furnace 3, and the second camera 502 detects the glass ribbon 6 in the low-temperature furnace 3 and transmits the detection signal to the DCS system; the glass ribbon 6 passes between the respective traction rollers 401 of the three pairs of traction rollers 41 of the traction equipment 4 in sequence, and the rotation speeds of the respective traction rollers 401 of the three pairs of traction rollers 41 are controlled to be the same through the servo motor connected to the traction roller shaft 402, and the traction rollers 401 of the traction rollers 41 on the same side of the glass ribbon 6 have the same rotation direction and the traction rollers 401 of the traction rollers 41 on both sides of the glass ribbon 6 have opposite rotation directions, and the traction rollers 401 of each pair of traction rollers 41 have the same clamping force on the glass ribbon 6. The first camera 501, the second camera 502, the first sensor 701, the second sensor 702, and the third sensor 703 detect whether the glass ribbon 6 exists and transmit the detection signal to the DCS system. When the first camera 501, the second camera 502, the first sensor 701, the second sensor 702, and the third sensor 703 do not detect the glass ribbon 6 for more than 5 seconds, they are fed back to the DCS system for judgment.

[0058] The DCS system makes judgments and takes measures based on the detection signals of the first camera 501, the second camera 502, the first sensor 701, the second sensor 702, and the third sensor 703, including the following situations:

[0059] 1. The third sensor 703 does not detect the glass strip 6, but the second sensor 702 detects the glass strip 6, which means it is a broken piece and no adjustment is made;

[0060] 2. The first sensor 701 does not detect the glass ribbon 6, but the second camera 502 detects the glass ribbon 6, which is the first broken board situation. The DCS system only starts the power increase of the medium temperature furnace heater 202 and the low temperature furnace heater 302, so that the glass can flow to the traction roller 41 by itself, and the DCS system opens three pairs of traction rollers 41. When the first sensor 701 detects the glass ribbon 6, the DCS system prepares the paired traction rollers 41 to clamp. When the second sensor 702 detects the glass ribbon 6, the paired traction rollers 41 under the first sensor 701 clamp. When the third sensor 703 detects the glass ribbon 6, the paired traction rollers 41 under the second sensor 702 clamp.

[0061] 3. When the first camera 501 does not detect the glass ribbon 6, it is the second broken board situation. The DCS system starts the power increase of the high temperature furnace heater 102, the medium temperature furnace heater 202, and the low temperature furnace heater 302, and opens the three pairs of traction rollers 41. Different from the sound and light alarm situation of the first broken board situation, the staff on duty needs to go to the site to check whether the glass can flow to the paired traction rollers 41 by itself. If not, manual adjustment and processing are performed.

[0062] After the processing is completed, the alarm is lifted and production is resumed.

[0063] The disclosed emergency disposal system for ultra-thin glass production and molding, when a broken plate occurs, the DCS system automatically opens the paired traction rollers 41 of the traction device 4 to make the broken glass fall, and the DCS system controls to increase the power of the high temperature furnace heater 102 at the bottom of the high temperature furnace 1, the medium temperature furnace heater 202 of the medium temperature furnace 2, and the low temperature furnace heater 302 of the low temperature furnace 3, so that the temperature of the glass ribbon 6 in the lower part of the high temperature furnace 1, the medium temperature furnace 2, and the low temperature furnace 3 increases, and the viscosity decreases, and the glass ribbon 6 falls to the traction device 4 by the self-weight of the glass. At the same time, the staff on duty is warned to check the glass status and equipment status.

[0064] The disclosed emergency disposal system for ultra-thin glass production and molding combines the emergency operation mode when a plate breakage occurs into one system, and realizes the functions of automatic detection, alarm and automatic temperature adjustment.
