Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic glass transmission, and in particular to an all-in-one pre-furnace connection film arrangement system, a film arrangement method and a device. Background Art

[0002] In the production and transmission process of photovoltaic glass, every link is crucial, especially the quality of the glass substrate is directly related to the performance and qualified rate of the final product. The normal arrangement of the glass in front of the tempering furnace is an indispensable production link. The stability of the glass spacing is an important link to ensure stable quality. When there are more glasses, it is very important to let them enter the furnace normally at the same spacing. Only when the glass spacing is stable can the temperature in the furnace be stable. The process of the furnace can be simply summarized as heating the glass to a certain temperature and then cooling it rapidly to increase the mechanical properties and thermal stability of the glass. Therefore, the process control of the furnace is actually the control of the heating process and the cooling process. In this process, whether it is heating or cooling, it is related to the control of temperature. Therefore, in the tempering process of glass, accurate temperature control is crucial to the quality of tempered glass. The temperature control of tempered glass is closely related to the arrangement of the glass in front of the furnace.

[0003] In actual production, if the films cannot be arranged normally, the tempering furnace will often give an alarm of glass being too long, or the glass gap being too small and the furnace will stop feeding. It is also possible that broken glass will enter the tempering furnace, causing major faults such as furnace blockage. It is also possible to give an alarm of delayed film delivery, causing the wind grille to automatically lift up and the glass cannot be cooled, thus becoming a defective product and interrupting production. The failure rate of the equipment is relatively high, affecting the normal production rhythm. Equipment failures such as film collision and tempering furnace alarm shutdown often occur, causing production interruptions and affecting output and equipment utilization rate.

[0004] The patent application with the publication number CN118791219A discloses a method for controlling the spacing of continuous tempered glass. Specifically, it is a method for controlling the spacing of continuous tempered glass, comprising a multi-segment tempering furnace, a glass loading end, a sheet feeding mechanism and a furnace discharge air grille section, wherein the sheet feeding mechanism is used to transport glass to the inner side of the multi-segment tempering furnace, and the feeding end of the multi-segment tempering furnace is provided with a glass feeding waiting spacing control component and a distance adjustment end segmented isolation component, and the glass loading end is installed on the outer side of the multi-segment tempering furnace; the distance adjustment end segmented isolation component applies an auxiliary driving force to the front section glass as the reserved gap control component is released, so that the front section glass enters the interior of the multi-segment tempering furnace faster than the rear section glass, until the glass feeding waiting spacing control component senses that the front and rear end glass have completed passing, and then sends the next loading measurement signal to the glass loading end, thereby completing the spacing adjustment before the glass loading is sent to the furnace. The device has a complex sheet arrangement structure and limitations, and is only used for models of two sizes at present, and it has not been combined with it in the actual production line to meet the production requirements. Summary of the invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide an all-in-one pre-furnace connection film arrangement system, a film arrangement method and a device, which cooperate with the transmission speed in the tempering furnace, the transmission speed of each roller of the cold working main line and the cold working branch line, the furnace entry spacing time and the optical fiber switch, and can be directly set through a visual human-computer interaction interface to select a suitable tempering furnace entrance signal. It has the characteristics of flexible operation and can be set at any time for different sizes, simple structure, and reduces the accidents of film collision and furnace shutdown.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] An all-in-one pre-furnace connection and arrangement system comprises a cold working main line 2 which can be arranged at the entrance of a tempering furnace 1. The cold working main line 2 is connected to a plurality of cold working branch lines 3. The cold working main line 2 and the cold working branch lines 3 are both a plurality of roller conveyors connected end to end. The cold working main line 2 is connected to each cold working branch line 3 via an overpass roller conveyor 5. An optical fiber switch 4 is arranged at the entrance of the tempering furnace 1, each roller conveyor and the overpass roller conveyor 5.

[0008] The cold working main line 2 is provided with a clamping device 6 for positioning the glass on the roller conveyor between the last overpass roller conveyor 5 in front of the tempering furnace 1 and the tempering furnace 1. The clamping device 6 is electrically connected to a clamping solenoid valve 7 for controlling the clamping of the clamping device 6.

[0009] A cylinder 9 for raising and lowering the overpass roller 5 is arranged below the overpass roller 5 , an upper limit magnetic switch 10 and a lower limit magnetic switch 11 are arranged inside the cylinder 9 , and the upper limit magnetic switch 10 and the lower limit magnetic switch 11 are electrically connected to an overpass raising and lowering solenoid valve 12 for controlling the cylinder 9 .

[0010] The servo motors for providing power in the tempering furnace 1, the cold working main line 2, the cold working branch line 3, as well as the optical fiber switch 4, the clamping solenoid valve 7, and the lifting solenoid valve 12 are all connected to the PLC control system by electrical signals.

[0011] A film arrangement method of an all-in-one furnace front connection film arrangement system comprises the following steps:

[0012] Step 1, the PLC control system obtains the conveying speed v1 in the tempering furnace 1, and sets the conveying speed of each roller table constituting the cold working main line 2 and the cold working branch line 3 to v2, and sets the furnace entry interval time to s;

[0013] Step 2, the PLC control system obtains the amount of glass in the tempering furnace 1 through the optical fiber switch 4 set at the entrance of the tempering furnace 1, so as to determine whether the tempering furnace 1 allows the entry of the glass. When the tempering furnace 1 allows the entry of the glass, the PLC control system controls the servo motor to normally operate and transport the glass at the speed v1 obtained in step 1 and the set speed v2. When the PLC control system determines that the tempering furnace 1 does not allow the entry of the glass, the optical fiber switch 4 at the entrance of the nth roller of the cold processing main line 2 detects whether glass has arrived. If no glass has arrived, no operation is taken, otherwise the transmission speed v2 of the nth roller is set to zero, that is, the glass is stopped from being transported. When the transmission speed v2 of the nth roller is zero, the optical fiber switch 4 at the entrance of the n-1th roller detects whether glass has arrived. If no glass has arrived, no operation is taken, otherwise the transmission speed v2 of the n-1th roller is set to zero, until the transmission speed v2 of the 1st roller is set to zero, wherein the nth roller is closest to the tempering furnace 1 and the 1st roller is farthest from the tempering furnace 1;

[0014] Step 3, when the PLC control system determines that the tempering furnace 1 allows the glass to be fed again, the conveying speed v2 of the nth roller after the step 2 is reset to zero is restored to the conveying speed set in step 1, that is, the glass is started to be conveyed, and at the same time, the optical fiber switch 4 at the entrance of the nth roller is used to detect whether glass has arrived. If glass has arrived, no operation is taken, otherwise the conveying speed v2 of the n-1th roller after the step 2 is reset to zero is restored to the conveying speed set in step 1, until the conveying speeds v2 of all rollers after the step 2 are reset to zero are restored to the conveying speed set in step 1;

[0015] Step 4, when the conveying speed v2 of the nth roller in steps 2 to 3 is the conveying speed set in step 1 to convey glass, and the optical fiber switch 4 at the entrance of the nth roller detects that the glass has completely left the nth roller, the PLC control system sets the conveying speed v2 of the nth roller to zero. When the conveying speed v2 of the nth roller is zero, the PLC control system detects whether there is glass arriving through the optical fiber switch 4 at the entrance of the n-1th roller. If no glass arrives, no action is taken. Otherwise, the conveying speed v2 of the n-1th roller is set to zero. Zero, until the conveying speed v2 of the first roller is reset to zero, and start timing, recorded as s1. When s1≥s, the PLC control system restores the conveying speed v2 of the nth roller after being reset to zero to the conveying speed set in step 1, and at the same time detects whether there is any glass arriving through the optical fiber switch 4 at the entrance of the nth roller. If glass arrives, no action is taken, otherwise the conveying speed v2 of the n-1th roller after being reset to zero is restored to the conveying speed set in step 1, until the conveying speed v2 of all rollers after being reset to zero are restored to the conveying speed set in step 1.

[0016] On the basis of steps 1 to 4, if the mth roller of the cold processing main line 2 is connected to the overpass roller 5, and when the optical fiber switch 4 at the entrance of the overpass roller 5 detects that glass has arrived, the PLC control system determines whether there is glass on the mth roller through the optical fiber switch 4 set at the entrance of the mth roller. If there is glass, no operation is taken. If there is no glass, the PLC control system controls the cylinder 9 to descend to the lower limit magnetic switch 11 through the overpass lifting solenoid valve 12 to transfer the glass to the mth roller. When the optical fiber switch 4 set at the entrance of the mth track detects that the glass has completely left the mth roller, the PLC control system controls the cylinder 9 to rise to the upper limit magnetic switch 11 through the overpass lifting solenoid valve 12, wherein n>m>0.

[0017] The roller conveyor of the cold working branch line 3 connected to the overpass roller conveyor 5 operates according to steps 2 to 4.

[0018] During the execution of steps 1 to 4, when the optical fiber switch 4 arranged at the roller entrance of the cold working main line 2 where the clamping device 6 is located detects the presence of glass, the PLC control system controls the clamping device 6 through the solenoid valve 7 to clamp and straighten the glass so that the glass can enter the tempering furnace smoothly.

[0019] An all-in-one furnace front connection and arrangement device, the device comprising a visual human-computer interaction interface, realizing information interaction with a PLC control system, and being used for setting the transmission speed v2 and the furnace entry spacing time s as described in claim 5.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The present invention adopts an optical fiber switch 4 with high sensitivity and short detection distance, which improves the detection sensitivity, improves the system accuracy, reduces the failure rate, and improves the production efficiency.

[0022] 2. The present invention designs an all-in-one pre-furnace sheet arrangement system and method, so that one tempering furnace 1 can correspond to multiple cold processing lines, thereby improving the utilization rate of the tempering furnace 1.

[0023] 3. The present invention cooperates with each other through the signal collection of the optical fiber switch 4 and the setting of the roller speed, and controls the glass spacing through the PLC control system, which not only improves the working efficiency of the tempering furnace 1 and the roller, but also stabilizes the temperature in the tempering furnace 1 and ensures product quality.

[0037] The lower limit magnetic switch 11 is CMSG-020 of AirTac

[0038] The flyover lifting solenoid valve 12 adopts 4V310-10.

[0040] like Figure 3 As shown, the servo motors for providing power in the tempering furnace 1, the cold working main line 2, the cold working branch line 3, as well as the optical fiber switch 4, the clamping solenoid valve 7, and the lifting solenoid valve 12 are all connected to the PLC control system by electrical signals.

[0041] The PLC control system S7-1500 automation system, it has extremely fast response time, efficient engineering configuration, and powerful communication functions.

[0042] A film arrangement method based on an all-in-one furnace front connection film arrangement system includes the following steps:

[0043] Step 1, the PLC control system obtains the conveying speed in the tempering furnace 1 as v1=38 m / min, and sets the conveying speed of each roller of the rollers constituting the cold working main line 2 and the two cold working branch lines 3 to v2=55 m / min, and sets the furnace entry time to s=450 ms;

[0044] Step 2, the PLC control system obtains the amount of glass in the tempering furnace 1 through the optical fiber switch 4 set at the entrance of the tempering furnace 1, so as to determine whether the tempering furnace 1 allows the entry of the glass. When the tempering furnace 1 allows the entry of the glass, the PLC control system controls the servo motor to normally operate and transport the glass at the speed v1 obtained in step 1 and the set speed v2. When the PLC control system determines that the tempering furnace 1 does not allow the entry of the glass, the optical fiber switch 4 at the entrance of the eleventh roller of the cold processing main line 2 is used to detect whether glass has arrived. If no glass has arrived, no operation is performed, otherwise the conveying speed v2 of the eleventh roller is set to zero, that is, the conveying of the glass is stopped. When the conveying speed v2 of the tenth roller is zero, the optical fiber switch 4 at the entrance of the tenth roller is used to detect whether glass has arrived. If no glass has arrived, no operation is performed, otherwise the conveying speed v2 of the ninth roller is set to zero, and so on, until the conveying speed v2 of the first roller is set to zero, wherein the tenth roller is closest to the tempering furnace 1 and the first roller is farthest from the tempering furnace 1;

[0045] Step 3, when the PLC control system determines that the tempering furnace 1 allows the glass to be fed again, the conveying speed v2 of the tenth roller after the step 2 is reset to zero is restored to 38 m / min set in step 1, that is, the glass starts to be conveyed, and at the same time, the optical fiber switch 4 at the entrance of the tenth roller is used to detect whether glass has arrived. If glass has arrived, no operation is taken, otherwise the conveying speed v2 of the ninth roller after the step 2 is reset to zero is restored to 38 m / min set in step 1, until the conveying speeds v2 of all rollers after the step 2 is reset to zero are restored to 38 m / min set in step 1;

[0046] Step 4, when the conveying speed v2 of the tenth roller in steps 2 to 3 is the conveying speed set in step 1 to convey glass, and the optical fiber switch 4 at the entrance of the tenth roller detects that the glass has completely left the tenth roller, the PLC control system sets the conveying speed v2 of the tenth roller to zero. When the conveying speed v2 of the tenth roller is zero, the PLC control system detects whether there is glass arriving through the optical fiber switch 4 at the entrance of the ninth roller. If no glass arrives, no action is taken, otherwise the conveying speed v2 of the ninth roller is set to zero until the tenth roller is delivered. The conveying speed v2 of one roller is reset to zero, and the timing is started, recorded as s1. When s1≥450ms, the PLC control system restores the conveying speed v2 of the ninth roller after being reset to zero to 38 m / min set in step 1. At the same time, the optical fiber switch 4 at the entrance of the ninth roller detects whether any glass has arrived. If glass has arrived, no action is taken. Otherwise, the conveying speed v2 of the eighth roller after being reset to zero is restored to the conveying speed set in step 1, until the conveying speed v2 of all rollers after being reset to zero is restored to 38 m / min set in step 1.

[0047] On the basis of steps 1 to 4, if the fifth and seventh rollers of the cold processing main line 2 are connected to the overpass roller 5, and when the optical fiber switch 4 at the entrance of the overpass roller 5 detects that glass has arrived, the PLC control system determines whether there is glass on the fifth or seventh roller through the optical fiber switch 4 set at the entrance of the mth roller. If there is glass, no operation is taken. If there is no glass, the PLC control system controls the cylinder 9 to descend to the lower limit magnetic switch 11 through the overpass lifting solenoid valve 12 to transfer the glass to the fifth or seventh roller. When the optical fiber switch 4 set at the entrance of the fifth or seventh track detects that the glass has completely left the fifth or seventh roller, the PLC control system controls the cylinder 9 to rise to the upper limit magnetic switch 12 through the overpass lifting solenoid valve 12.

[0048] The roller tables of the two cold working branch lines 3 are operated according to steps 2 to 4.

[0049] During the execution of steps 1 to 4, when the optical fiber switch 4 at the entrance of the eighth roller of the cold working main line 2 where the clamping device 6 is located detects the presence of glass, the PLC control system controls the clamping device 6 through the solenoid valve 7 to clamp and straighten the glass so that the glass can enter the tempering furnace smoothly.
