Abstract
Description
Technical Field

[0002] The development prospects of photovoltaic double-glass modules are broad. The deep processing technology of photovoltaic glass is edging / drilling → coating / silk screen printing → tempering → packaging. Each process is connected by a connecting roller to form an assembly line.
[0003] Currently, when a section of the photovoltaic glass deep processing roller conveyor fails or becomes blocked, manual intervention is required to adjust the glass density on the roller conveyor.

[0058] Please refer to Figures 1 to 5 As shown, in order to achieve the above-mentioned purpose, the present invention proposes a glass production line, which includes a tempering furnace, at least one transmission device and a control device. The tempering furnace is used to temper glass. Each transmission device includes at least two conveying mechanisms and at least one spacing mechanism 100. The spacing mechanism 100 is located between two adjacent conveying mechanisms. The conveying mechanism is provided with a first channel, and the spacing mechanism 100 is provided with a second channel 12. The first channel and the second channel 12 cooperate to form a transmission channel. The transmission channel is used to convey glass. One end of the transmission channel is connected to the entrance of the tempering furnace. The control device is electrically connected to the spacing mechanism 100, and the control device is used to control the spacing of the glass located in the second channel 12.
[0059] In this embodiment, if Figure 1As shown, the glass production line includes but is not limited to the production of photovoltaic glass and ordinary glass, and photovoltaic glass includes but is not limited to ultra-thin photovoltaic glass, ultra-white photovoltaic glass and surface-coated photovoltaic glass, and the glass can be formed by rolling, float glass and other methods, which are not limited here. The tempering furnace is a production equipment in the glass production line. The tempering furnace is used to perform high-temperature rapid cooling and tempering of the glass to change the internal structure of the glass and improve the strength and impact resistance of the glass. The glass production line also includes but is not limited to a melting furnace and a curing furnace, wherein the melting furnace is used to melt the glass raw materials to make the glass molten and formed into a flat structure, and the curing furnace is used to cure the coating on the surface of the glass, such as by light curing. At the same time, the glass production equipment also includes a stretching machine, an edge grinding and cleaning machine, a return inspection and washing system, a defect detection and subsequent packaging and palletizing mechanisms, and a transmission device is provided between the melting furnace and the curing furnace, and between the curing furnace and the tempering furnace. The above-mentioned stretching machine, edge grinding and cleaning machine, return inspection and washing system, etc. are all provided on the transmission channel or side of the transmission device to perform relevant process treatment on the glass.
[0060] In this embodiment, the transmission device is a mechanism for transmitting glass. It can realize the transmission of glass by rotating multiple parallel and spaced nitrile rubber rollers 2, or it can realize the transmission and transportation of glass by a double-speed chain or chain plate. It is not limited here. At the same time, the transmission device is also provided with a driving member 3 to drive the roller 2 or chain to rotate. The driving member 3 can be a servo motor, etc. The transmission device forms a transmission channel, which is located between the two vertical frames, and the transmission channel is a planar structure to carry and transport the glass.
[0061] In this embodiment, each transmission device includes at least two conveying mechanisms and at least one spacing mechanism 100. The conveying mechanism and the spacing mechanism 100 have similar structures. They can be a plurality of parallel and spaced nitrile rubber rollers 2 or chains or chain plates arranged between two vertical frames to realize the transportation of glass. At least one spacing mechanism 100 is located between two adjacent conveying mechanisms. The conveying mechanism forms a first channel for conveying glass, and the spacing mechanism 100 forms a second channel 12 for conveying glass and adjusting the spacing between glasses, so that a second channel 12 is located between the two first channels and is interconnected to form a transmission channel.
[0062] It can be understood that the spacing mechanism 100 is electrically connected to the control device, and the control device can control the moving speed of at least two adjacent glasses on the spacing mechanism 100, that is, when a glass moves in the front, the speed of the adjacent and rear glass is automatically adjusted to ensure that the spacing between the two glasses on the second channel 12 is within a suitable range. The spacing mechanism 100 can accurately adjust the speed of the second channel 12 in a zoned and timed manner. Specifically, infrared sensors can be set at the outlet end 122 and the inlet end 121 of the second channel 12. The infrared sensors are electrically connected to the control device. When the front and rear glasses pass through the inlet end, the infrared sensors are electrically connected to the control device. 121, the timer provided in the control device can be used to time the distance between the two glasses, and when the two glasses are in different areas of the second channel 12, the speed of the two glasses can be adjusted respectively to change the distance between the two glasses. When the distance between the two glasses is large when entering the second channel 12, and the rear glass enters one of the areas of the second channel 12, the rear glass can be accelerated to reduce the distance between the front and rear glasses. When the distance between the two glasses is small when entering the second channel 12, the distance between the front and rear glasses can be increased by reducing the transmission speed of a certain area of the second channel 12.
[0063] At the same time, the second channel 12 is provided with at least two areas for adjusting the speed of the glass to change the speed of the moving glass simultaneously or in a time-sharing manner. The spacing mechanism 100 can be provided with at least two driving members 3, each driving member 3 is independently driven and connected to multiple rollers 2, so that each driving member 3 independently controls an adjustment area, and independently controls the operation of at least two driving members 3 through the control device to adjust the glass located in the second channel 12. The present application can automatically adjust the spacing between glasses by setting up a spacing mechanism 100. On the one hand, it avoids the shutdown and pressure of the furnace caused by untimely intervention in the production line rhythm. On the other hand, it reduces manual intervention in the production line rhythm in traditional production, thereby reducing the risk of collision and stacking caused by manual intervention. At the same time, the automatically adjusted glass spacing can also ensure that the tempering furnace has a stable furnace temperature, avoid large temperature changes inside the tempering furnace, effectively improve the tempering effect, and increase production capacity.
[0064] In one embodiment, the spacing mechanism 100 includes a mounting frame 1, multiple rollers 2 and multiple driving members 3. The mounting frame 1 forms a mounting gap 11, and the multiple rollers 2 are rotatably arranged in the mounting gap 11. The multiple rollers 2 are arranged in parallel and spaced apart to form a second channel 12. The multiple driving members 3 are arranged on the mounting frame 1, each driving member 3 is electrically connected to the control device, and the output end of each driving member 3 is transmission-connected to part of the rollers 2.
[0065] In this embodiment, if Figure 1As shown, the spacing mechanism 100 is provided with a mounting frame 1, which is a structural support component of the spacing mechanism 100 and is used to mount and support the rollers 2 and the driving members 3. The mounting frame 1 can be a structure such as a frame, a base or a transmission frame, which is not limited here. In the field of glass production, the mounting frame 1 is usually composed of two vertical frames arranged relative to each other, and a mounting gap 11 is formed between the two vertical frames. A plurality of rollers 2 are rotatably connected to the two vertical frames and arranged in the mounting gap 11. The plurality of rollers 2 are arranged in parallel and spaced apart in a direction perpendicular to the axis direction of the rollers 2 to form a second channel 12. At the same time, the spacing mechanism 100 also includes a plurality of driving members 3. The plurality of driving members 3 are arranged in one of the two vertical frames, and the output end of each driving member 3 is transmission-connected to a portion of the rollers 2. Each driving member 3 is electrically connected to the control device.
[0066] It can be understood that multiple driving members 3 are transmission connected to the rollers 2 that constitute the second channel 12, and each driving member 3 is transmission connected to part of them, so that the second channel 12 forms multiple adjustment areas according to the number of driving members 3, and there are multiple rollers 2 in each adjustment area. The operation of each driving member 3 is controlled simultaneously or in a time-sharing manner by the control device, so that each driving member 3 can control the multiple rollers 2 to which it is transmission connected, so as to synchronously adjust the rotation speed of the multiple rollers 2, thereby adjusting the moving speed of the glass located in the adjustment area.
[0067] In this embodiment, the spacing mechanism 100 includes three driving members 3, each of which is connected to a plurality of rollers 2 in a transmission manner, and the three driving members 3 are connected to all the rollers 2 constituting the second channel 12 in a transmission manner. At this time, the second channel 12 forms three adjustment areas: front, middle and rear. The three adjustment areas can accurately and independently adjust the speed of the glass located in their respective areas, thereby adjusting the spacing between adjacent glasses to achieve automatic and precise adjustment of the glass spacing.
[0068] In one embodiment, the second channel 12 includes an outlet end 122 and an inlet end 121, and the outlet end 122 and the inlet end 121 are connected to the first channel; wherein, one of the multiple driving members 3 is located at the inlet end 121 and is transmission-connected to the multiple rollers 2 located at the inlet end 121; another one of the multiple driving members 3 is located at the outlet end 122 and is transmission-connected to the multiple rollers 2 located at the outlet end 122.
[0069] In this embodiment, if Figure 1 As shown, the second channel 12 includes an inlet end 121 and an outlet end 122. The inlet end 121 and the outlet end 122 can be connected to the first channel formed by the transmission mechanism, or can be connected to production storage equipment such as a sheet storage machine, a stretching machine, etc., which is not limited here. One of the multiple driving members 3 is located at the inlet end 121, and another one of the multiple driving members 3 is located at the outlet end 122.
[0070] It can be understood that an intermediate section 123 is formed between the inlet end 121 and the outlet end 122. The inlet end 121 is the front adjustment area mentioned above, the outlet end 122 is the rear adjustment area mentioned above, and the intermediate section 123 is the middle adjustment area mentioned above. The driving member 3 located at the inlet end 121 is transmission-connected to the multiple rollers 2 located at the inlet end 121 of the second channel 12, the driving member 3 located at the outlet end 122 is transmission-connected to the multiple rollers 2 located at the outlet end 122 of the second channel 12, and the driving member 3 located at the intermediate section 123 is transmission-connected to the multiple rollers 2 between the inlet end 121 and the outlet end 122, thereby forming three independent adjustment areas on the second channel 12. At the same time, at least one driving member 3 is also provided between the inlet end 121 and the outlet end 122 to form at least one adjustment area between the inlet end 121 and the outlet end 122, thereby forming at least three adjustment areas in the second channel 12.
[0071] Furthermore, the adjustment area at the inlet end 121 can adjust the speed of the glass entering the second channel 12. At the same time, the adjustment area at the outlet end 122 can adjust the speed of the glass leaving the second channel 12, thereby adjusting the distance between the glasses.
[0072] In one embodiment, the plurality of driving members 3 include a first driving member 31, a second driving member 32 and a third driving member 33. The first driving member 31 is arranged at the outlet end 122, and the first driving member 31 is transmission-connected to at least two rollers 2 located at the outlet end 122. The second driving member 32 is arranged at the inlet end 121, and the second driving member 32 is transmission-connected to at least four rollers 2 located at the inlet end 121. The third driving member 33 is arranged between the first driving member 31 and the second driving member 32, and the third driving member 33 is transmission-connected to at least three rollers 2 located between the inlet end 121 and the outlet end 122.
[0073] In this embodiment, if Figure 1 As shown, the spacing mechanism 100 includes a first driving member 31, a second driving member 32 and a third driving member 33, and the first driving member 31, the second driving member 32 and the third driving member 33 are arranged on one of the two stands, and the first driving member 31, the second driving member 32 and the third driving member 33 are all electrically connected to the control device, wherein the first driving member 31 is connected to at least two rollers 2 located at the outlet end 122, the second driving member 32 is connected to at least four rollers 2 located at the inlet end 121, and the third driving member 33 is connected to the remaining rollers 2 located on the second channel 12.
[0074] It can be understood that the first driving member 31, the second driving member 32 and the third driving member 33 are transmission-connected to all the rollers 2 located on the second channel 12 to divide the second channel 12 into three adjustment areas, namely the inlet end 121, the middle section 123 and the outlet end 122. The number of rollers 2 in the three areas is different, among which the number of rollers 2 located at the inlet end 121 is the largest, the number of rollers 2 located at the outlet end 122 is the least, and the number of rollers 2 in the middle section 123 is between the number of rollers 2 at the inlet end 121 and the outlet end 122, so that the adjustment lengths of the front, middle and rear areas form a stepped arrangement, effectively improving the adjustment accuracy and efficiency of the rollers 2, and can gradually accelerate or decelerate to improve the smoothness and continuity of the glass speed adjustment.
[0075] Specifically, when the first piece of glass enters the adjustment area at the outlet end 122, the infrared sensor detects the head of the first piece of glass, and at this time continuously transmits the detection signal to the control device, which controls the first driving member 31, the second driving member 32 and the third driving member 33 to decelerate so that the speed at the outlet end 122 is the same as the speed of the glass transmitted by the transmission device. When the tail of the first piece of glass leaves the infrared sensor, the second piece of glass enters the inlet end 121, and the control device controls the second driving member 32 and the third driving member 33 to accelerate to increase the speed of the glass at the inlet end 121. Enter the second channel 12 as quickly as possible and maintain a suitable distance from the previous piece of glass. When the second piece of glass enters the middle section 123 driven by the third driving member 33, keep the speed of the second driving member 32 and the third driving member 33 consistent, and decelerate the first driving member 31. At this time, the speeds of the first driving member 31, the second driving member 32 and the third driving member 33 are consistent. The first piece of glass leaves the second channel 12, and the second piece of glass also quickly enters the exit end 122 while maintaining a suitable distance from the previous piece of glass, and is consistent with the transmission speed of the transmission device, thereby realizing the adjustment of the glass spacing.
[0076] Among them, the multiple rollers 2 located at the inlet end 121 need to first adjust the speed of the glass entering the second channel 12, so the number of rollers 2 at the inlet end 121 is relatively large, and the rollers 2 located at the outlet end 122 are mainly used to keep the speed of the glass consistent with the transmission speed of the transmission structure, so the number of rollers 2 at the outlet end 122 is relatively small. At the same time, the number of rollers 2 in the middle section 123 is set to be greater than the number of rollers 2 at the outlet end 122, and less than the number of rollers 2 at the inlet end 121, so as to ensure smooth and continuous adjustment of the glass speed in the front, middle and rear areas, thereby stably and quickly adjusting the spacing between the glasses.
[0077] In one embodiment, the spacing mechanism 100 further includes a plurality of chains, each roller shaft 2 is provided with a driven sprocket along its axis; each driving member 3 is provided with a driving sprocket, and each chain is meshedly connected with a driving chain and a plurality of driven sprockets.
[0078] In this embodiment, a driven sprocket is provided on each roller shaft 2 in the second channel 12, and one end of the driven sprockets of the multiple roller shafts 2 is located on one side of the second channel 12, so that the multiple driving members 3 located on this side can be connected to the driven sprocket. Specifically, a driving sprocket is provided at the output end of each driving member 3, and the driving sprocket and the multiple driven sprockets are meshed and connected by a chain to drive the multiple roller shafts 2 to rotate.
[0079] It can be understood that by adjusting the number of chain links, the number of rollers 2 connected to a drive member 3 can be accurately adjusted. For example, the first drive member 31 mentioned above can be connected to at least two rollers 2, so that the size of the area adjusted by each drive member 3 on the second channel 12 can be adjusted, thereby improving the versatility and adaptability of the spacing mechanism 100 and the spacing device.
[0080] In one embodiment, the spacing mechanism 100 further includes a plurality of detection members 4, which are disposed on the mounting frame 1 and electrically connected to the control device; wherein some of the detection members 4 are located at the outlet end 122 and the inlet end 121, and another portion of the detection members 4 are located between the outlet end 122 and the inlet end 121.
[0081] It is understandable that if Figure 1 As shown, the detection member 4 can be a photoelectric sensor or an infrared sensor. The detection member 4 is electrically connected to the control device. The detection member 4 is used to detect the position of the glass in the second channel 12, so that the position of the glass in the second channel 12 can be transmitted to the control device, and the control device is used to control the operation of multiple driving members 3, so as to be able to adjust the speed of the glass in multiple adjustment areas in the second channel 12 in a zoned and time-divided manner, so as to accurately and quickly adjust the distance between adjacent glasses.
[0082] In one embodiment, the plurality of detection members 4 include a first detection member 4, a second detection member 4 and a third detection member 4, the first detection member 4 is located at the outlet end 122, the second detection member 4 is located at the inlet end 121, and the third detection member 4 is located between the first detection member 4 and the second detection member 4; wherein the distance between the first detection member 4 and the third detection member 4 is less than the length of the glass along its transmission direction.
[0083] In this embodiment, the first detection member 4, the second detection member 4 and the third detection member 4 are all electrically connected to the control device, and the first detection member 4, the second detection member 4 and the third detection member 4 are arranged at intervals along the transmission direction of the second channel 12, and when the glass enters the second channel 12, it passes through the second detection member 4, the third detection member 4 and the first detection member 4 in sequence, wherein the third detection member 4 is located between the first detection member 4 and the second detection member 4, and the distance between the first detection member 4 and the third detection member 4 is less than the length of the glass along its transmission direction.
[0084] It can be understood that when the first piece of glass enters the second channel 12, the second detection member 4 located at the inlet end 121 detects the first piece of glass and transmits the detection result to the control device. The control device controls the second drive member 32 and the third drive member 33 to accelerate to control the acceleration of multiple rollers 2 at the inlet end 121 and the middle section 123, thereby quickly transferring the first piece of glass from the inlet end 121 to the outlet end 122. When the first piece of glass enters the outlet end 122, the first detection member 4 located at the outlet end 122 detects the head of the first piece of glass. At this time, the first detection member 4 transmits the detection result to the control device. The control device controls the first drive member 31, the second drive member 32 and the third drive member 33 to decelerate at the same time, so that the speed of the first piece of glass is consistent with the speed of the glass transmitted by the transmission device.
[0085] Furthermore, when the tail of the first piece of glass leaves the third detection member 4, the first piece of glass leaves the middle section 123 and enters the outlet end 122, and the second detection member 4 detects that the second piece of glass has entered the second channel 12 at the inlet end 121 of the second channel 12. At this time, the second detection member 4 and the third detection member 4 transmit the detection results to the control device, and the control device controls the second driving member 32 and the third driving member 33 to speed up, so as to transmit the second piece of glass to the second channel 12 as soon as possible to ensure that the distance between the second piece of glass and the first piece of glass is appropriate; finally, when the head of the second piece of glass passes through the third detection member 4, the second piece of glass enters the middle section 123. At this time, the control device controls the speed of the first driving member 31, the second driving member 32 and the third driving member 33 to remain consistent to complete the adjustment of the distance between the two adjacent glasses.
[0086] It can be understood that the present application sets multiple adjustment areas in the second channel 12, and controls the transmission speed of two adjacent glasses in the second channel 12 in different areas and at different times, thereby achieving the adjustment of the distance between two adjacent glasses, effectively reducing manual intervention in the production line, reducing the risk of glass collision and overlap, and making the transmission speed of the glass consistent with the transmission speed of the adjacent transmission device, thereby ensuring the smoothness and continuity of the glass transmission.
[0087] In one embodiment, the glass production line also includes a melting furnace and a curing furnace, and the curing furnace is located between the melting furnace and the tempering furnace; the glass production line includes two transmission devices, one transmission device is arranged between the melting furnace and the curing furnace, and is connected to the outlet of the melting furnace and the inlet of the curing furnace; the other transmission device is located between the curing furnace and the tempering furnace, and is connected to the outlet of the curing furnace and the inlet of the tempering furnace.
[0088] It can be understood that the melting furnace is used to melt the glass raw materials so that the glass becomes molten and is formed into a flat structure. The curing furnace is used to solidify the coating on the surface of the glass, such as through light curing. One of the two transmission devices is arranged between the melting furnace and the curing furnace to transmit the glass from the melting furnace to the curing furnace and adjust the spacing of the glass before entering the curing furnace. The other transmission device is located between the curing furnace and the tempering furnace to transmit the glass from the curing furnace to the tempering furnace and adjust the spacing of the glass before entering the tempering furnace.
[0089] In one embodiment, the transmission device includes a front chip storage machine and a rear chip storage machine, and the front chip storage machine and the rear chip storage machine are arranged at an interval; the spacing device includes two spacing mechanisms 100, one spacing mechanism 100 is located between the front chip storage machine and the rear chip storage machine, and the other spacing mechanism 100 is located on the side of the rear chip storage machine away from the front chip storage machine.
[0090] In this embodiment, the front sheet storage machine and the rear sheet storage machine are usually arranged on the transmission channel of the transmission device, and the front sheet storage machine is located upstream of the rear sheet storage machine. Process equipment such as a curing furnace is usually arranged between the front sheet storage machine and the rear sheet storage machine. When the number of glasses on the transmission channel is large, the front sheet storage machine and the rear sheet storage machine are used to store the glasses on the transmission channel, or when the number of glasses on the transmission channel is small, the glasses on the front sheet storage machine and the rear sheet storage machine can also be released to the transmission channel to realize the adjustment of the number and spacing of glasses on the transmission channel.
[0091] It can be understood that the front and rear storage machines are used to temporarily store glass and store or release the glass at the appropriate time. The spacing device includes two spacing mechanisms 100, so that after the front and rear storage machines release the glass, they can quickly adjust the spacing between two adjacent glasses through the spacing mechanism 100 to ensure that the glass can enter process equipment such as curing furnaces, tempering furnaces, etc. at a suitable spacing, thereby improving the continuity and stability of glass production and processing and improving production efficiency.
[0092] The present invention further provides a spacing method, which is applied to the glass production line as described above. The spacing method comprises the following steps:
[0093] S10, detecting whether there is an empty line or no glass area in the glass production line;
[0094] S20a, if yes, obtain the duration of the no-slice area in the empty line;
[0095] S30, controlling the spacing mechanism 100 to adjust the spacing according to the duration to adjust the spacing between the glass panes;
[0096] S20b: If no, keep the glass production line running normally.
[0097] In this embodiment, if Figure 2 As shown, the spacing method is applied to the above-mentioned glass production line and is implemented by the spacing mechanism 100. First, a visual detection method or a manual detection method is used to detect whether there are empty lines and no glass areas in the glass production line. Empty lines and no glass means that no glass flows through all or part of the areas in the glass production line for a period of time. Specifically, the glass production line is usually equipped with multiple operating lines, including a main line and multiple sub-lines. Among them, affected by upstream production equipment such as furnaces, multiple sub-lines may be temporarily empty, thereby reducing the amount of glass in the entire glass production line.
[0098] Furthermore, if it is detected that there is an empty line and no-piece area on the glass production line, the timing is started to obtain the duration of the empty line in the empty line and no-piece area, that is, during the duration, all or part of the area of the glass production line is in a glass-free state. At this time, it is necessary to control the spacing mechanism 100 to adjust the spacing according to the duration of the empty line, and adjust the spacing between the glasses so that the glasses enter the tempering furnace at the same interval, reducing the large temperature variation in the tempering furnace caused by the different number of glasses entering the tempering furnace per unit time, ensuring the temperature stability in the tempering furnace, improving the tempering effect of the glass, and improving production efficiency.
[0099] In one embodiment, the step of controlling the spacing mechanism 100 to adjust the spacing according to the duration to adjust the spacing between the glass panes includes:
[0100] S301, determine whether the duration is greater than 30 seconds;
[0101] S301a, if yes, control the spacing mechanism 100 to increase the spacing between the glass panes;
[0102] S301b, if not, control the spacing mechanism 100 to shrink to reduce the distance between the glass.
[0103] In this embodiment, if Figure 3As shown, the duration can be determined according to the actual production rhythm. If the production rhythm is fast, such as when the production rhythm is above 15 pieces per minute, it indicates that a large number of glasses enter the glass production line per unit time. At this time, the detection threshold of the duration can be appropriately lowered, such as setting it to less than 30 seconds, such as 20 seconds or 15 seconds, so that when an empty line or no-piece area appears, the distance between the glasses can be quickly adjusted to reduce the pressure and accumulation of the glass. If the production rhythm is slow, such as when the production rhythm is below 12 pieces per minute, the detection threshold of the duration can be appropriately increased, such as setting it to more than 30 seconds. On the basis of the normal operation of the glass production line, the spacing method can be used to adjust the glass distance.
[0104] It is understandable that it is usually calculated based on the production rhythm of 11 pieces per minute to determine whether the duration is greater than 30 seconds. If it is greater than 30 seconds, there is an imbalance in the glass in the glass production line, with some areas having more and some areas having less, which will make the spacing of the glass entering the tempering furnace uneven. The spacing mechanism 100 can be controlled to perform a spacing process on the glass entering the second channel 12 to increase the spacing between two adjacent glasses on the entire glass production line, thereby filling the local gaps caused by the empty line and no-piece area, so that all the glasses on the glass production line have appropriate and approximately the same spacing, and enter the tempering furnace stably and continuously, thereby ensuring the temperature stability of the tempering furnace and improving the tempering effect.
[0105] Furthermore, if it is less than 30 seconds, it indicates that there is still a large amount of glass on the glass production line. The spacing mechanism 100 can be used to shorten the spacing of the glass on the glass production line to reduce the distance between two adjacent glasses, thereby ensuring that within a unit time, as many glasses as possible on the glass production line enter the tempering furnace with the same spacing, thereby effectively improving production efficiency.
[0106] In one embodiment, the step of controlling the spacing mechanism 100 to adjust the spacing according to the duration to adjust the spacing between the glass panes further includes:
[0107] S302, controlling the distance between the first to fifth glass sheets to increase by 400 mm or decrease by 300 mm;
[0108] S303, controlling the distance between the 6th to 10th glass sheets to increase or decrease by 100 mm;
[0109] S304, controlling the distance between the 11th to 15th glass sheets to increase or decrease by 100 mm;
[0110] S305: Control the spacing between more than 16 pieces of glass to increase by 300 mm or decrease by 400 mm.
[0111] It is understandable that if Figure 4As shown, the adjustment of the glass spacing is carried out in sequence according to the number and position of the glasses, that is, the distance is increased or decreased in a step-by-step manner. From the 1st to the 5th glass, since they are in an earlier position, the glass spacing needs to be quickly adjusted in a short time. Therefore, the distance can be increased to 400mm when pulled, and can be decreased by 300mm when decreased. When it is from the 6th to the 15th glass, the distance between two adjacent glasses can be controlled to increase by 100mm or decrease by 100mm to achieve distance adjustment. Furthermore, when there are more than 16 glasses, in order to retain more adjustment margin, the adjustment value is increased again, increasing by 300mm when pulled and decreasing by 400mm when decreased, which effectively improves the stability and continuity of the glass spacing adjustment.
[0112] In one embodiment, each glass production line includes a front sheet storage machine and a rear sheet storage machine. After the spacing mechanism 100 is controlled to adjust the spacing according to the duration to adjust the spacing between the glasses, the spacing method further includes:
[0113] S401, obtaining the number of warning glass pieces according to the temperature of the tempering furnace;
[0114] S402, obtaining the real-time number of glass sheets in the rear glass storage machine;
[0115] S403, determining whether the real-time number of glass pieces is greater than the warning number of glass pieces;
[0116] S403a: If yes, control the front and rear wafer storage machines to release wafers simultaneously;
[0117] S403b: If not, control the front wafer storage machine to continuously put wafers.
[0118] In this embodiment, if Figure 5 As shown, the front and rear glass accumulators are used to store glass to increase the impact resistance of the glass production line, improve the continuity of glass production, and stabilize production. However, the front and rear glass accumulators on a production line are far apart. When the rear glass accumulator stores 12-17 pieces, the rear glass accumulator triggers an alarm mechanism, indicating that it is out of glass. At this time, the front glass accumulator releases the glass, but it takes 4-8 minutes for the glass to travel from the front glass accumulator to the rear glass accumulator. In many cases, the rear glass accumulator is out of glass before it reaches the rear glass accumulator, resulting in glass breakage and failure to ensure glass continuity.
[0119] It can be understood that the spacing method also includes a linkage method for releasing the sheets of the front sheet storage machine and the rear sheet storage machine. First, the real-time temperature of the tempering furnace needs to be obtained, and the minimum warning number of glass sheets of the rear sheet storage machine is determined according to the real-time temperature of the tempering furnace. Specifically, when the temperature of the tempering furnace is high, in order to ensure the tempering effect of the glass, more glass needs to be input into the tempering furnace per unit time to reduce the impact of high temperature on a single glass. Then, the real-time number of glass sheets of the rear sheet storage machine is obtained, that is, the number of glass sheets stored in the rear sheet storage machine at this time, and whether the real-time number of glass sheets is greater than the warning number of glass sheets is determined. If the real-time number of glass sheets is greater than the warning number of glass sheets, The number of warning glass pieces indicates that there are more glasses in the rear glass storage machine at this time, and it is sufficient to ensure that the front glass storage machine and the rear glass storage machine release the glasses at the same time. If the real-time number of glass pieces is less than the number of warning glass pieces, it indicates that there are fewer glasses in the rear glass storage machine at this time. At this time, the front glass storage machine is controlled to release the glasses continuously, so as to transfer more glasses to the rear glass storage machine in a short time, so as to ensure the stability of the number of glasses stored in the rear glass storage machine, thereby ensuring the stability of the number of glasses entering the tempering furnace. In conjunction with the row spacing mechanism 100, the transmission speed of the glass is synchronously adjusted, which effectively improves the glass adjustment efficiency of the glass production line and improves the processing efficiency of the glass production line.
