Description

Technical Field

[0001] The invention belongs to the technical field of glass production equipment, and in particular relates to a glass production line linkage patch control system and method. Background Art

[0002] Conventional glass tempering often uses a multi-line integration method, that is, multiple glass branches are merged into a main line after passing through the process equipment and before tempering to discharge the glass to the tempering furnace, thereby improving the production efficiency of the entire production line.

[0003] Tempering furnaces require a stable and uninterrupted row of glass sheets to enter, but because the loading and stacking of glass sheets requires a certain interval or a problem occurs in a process equipment in a single branch line, resulting in insufficient glass on the line, there will be a problem of insufficient glass collected in front of the tempering furnace. Therefore, the tempering furnace needs to be frequently stopped to collect glass sheets on the main line, and then the glass sheets are put in after the required number of sheets is reached, which reduces production efficiency. Therefore, an efficient glass filling system is urgently needed to maintain the uninterrupted operation of the tempering furnace and improve production efficiency.

[0004] For example, a Chinese invention patent discloses a device and method for patching a glass production line [application number: CN202310670677.5]. The invention discloses a device and method for automatically collecting and patching photovoltaic glass transmission, wherein a transmission device, a lifting device, a transmission position detection device and a lifting position detection device are all installed on a frame, the lifting product support rod is horizontal and lower than the transmission device, the lifting product support rod is installed on the lifting device, the transmission drive motor in the transmission device, the lifting drive motor in the lifting device, the transmission position detection device and the lifting position detection device are all connected to the automatic control system signal; the transmission position detection device is used to detect the position of the photovoltaic glass and transmit it to the automatic control system in real time; the lifting position detection device is used to detect the position of the lifting product support rod and transmit it to the automatic control system in real time; the automatic control system is used to determine whether it is necessary to collect or patch the photovoltaic glass according to the detection result of the transmission position detection device, and control the start and stop of the transmission device and the lifting device.

[0005] Although the invention provides a device that can collect patches on a glass production line and a corresponding method of use, the device is mainly used to collect patches to cope with emergencies on the production line. If it is used to continuously add patches to the production line, it is necessary not only to set parameters for each patch device on each line individually for management, but also to pre-store and continuously replenish glass sheets. The production efficiency is relatively low and the labor cost is high, which is particularly insufficient in the multi-production line mode. Summary of the invention

[0006] The object of the present invention is to provide a fully automated glass production line linkage patch control system that can efficiently manage patches on the production line in order to solve the above problems.

[0007] Another object of the present invention is to provide a method for operating the above system in view of the above problem.

[0008] In order to achieve the above-mentioned purpose, the glass production line linkage patch control system of the present invention adopts the following technical solutions:

[0009] The system involved in the method includes a sensor module, a glass supply merging system for merging glass sheets from each branch line to the main line, a user control device, a patch branch line, an operation control component and a PLC control module. The glass supply merging system and the patch branch line use a roller mode to transport glass sheets; the patch branch line includes a transition roller 1 arranged in front of the overpass roller for temporarily storing glass sheets, and the transition roller 1 can sense the glass sheets; the operation control component includes a frequency converter controlled by the PLC control module that can adjust the drive motors of each roller and a solenoid valve that controls the action of the overpass roller; the PLC control module can control the sensor module and receive its signal; the user control device is connected to the PLC control module and can transmit the patch signal. The glass sheet branch line merging system comprises a main line segment after the glass branch lines are merged, and the patch branch line and the main line segment have an intersection where an overpass roller that can be controlled to move up and down by the operation control component is arranged; a sensor module is also arranged in the intersection, and the sensor module comprises a plurality of photoelectric sensors connected to the PLC control module, and the photoelectric sensors comprise a first sensor and a second sensor arranged before and after the main line segment at the intersection for detecting the passing of glass sheets, and a third sensor and a fourth sensor respectively arranged before and after the patch branch line at the intersection; the method for controlling the system comprises the following steps:

[0010] S1: Power on and initialize the glass supply and merging system, and power on the user control device, sensor module, and PLC control module;

[0011] S2: The user controls the device to set the mode to the automatic patching state, sets the patching parameters, and generates a patching condition mathematical model based on the patching parameters. At this time, the control components and the patching branch line are powered on, and the patching branch line starts to transport glass sheets;

[0012] S3: In the automatic state, the first sensor array composed of the first sensor and the second sensor sends a signal according to the change of light intensity to determine the passing of glass pieces, and feeds back to the PLC control module to calculate the sum of the number of glass pieces that have passed the current main line segment, store the data and interact with the patch parameters in real time to determine whether the patch conditions are met;

[0013] S4: After the patching conditions are met, the PLC control module commands the operation control component to control the overpass roller to perform the patching action and complete the patching; the sensor module sends a signal, and the number of glass sheets that have passed the corresponding main line segment stored in the PLC control module is reset to zero; S4 specifically includes the following steps:

[0014] S41: confirming, based on the signal of the first lifting sensor, that the overpass roller is in the initial mode of normal operation of the upper and lower rollers;

[0015] S42: The third sensor and the fourth sensor form a second sensor array. After the patch requirement is met, it is confirmed that there is no glass sheet at the intersection of the main line segment according to the signal of the first sensor array, and it is confirmed that there is a glass sheet at the intersection of the patch branch line according to the signal of the second sensor array. The PLC control module uses the frequency converter to at least stop the operation of the roller and the transition roller of the patch branch line at the intersection, and at the same time stops the operation of the main line segment roller or keeps the main line segment roller running, but according to the signal sent by the first sensor array, it is determined to ensure that the glass sheet in front of the entrance of the main line segment along the direction of the roller at the intersection maintains a safe distance from the intersection;

[0016] S43: The PLC control module controls the roller section of the patch branch line at the intersection through the solenoid valve to carry the glass sheet up or down and integrate it into the main line section roller line, and starts to transport the glass sheet to the main line section roller line;

[0017] S44: The roller section of the patch branch line at the intersection is restored to the initial state; after the PLC control module receives the specific signal from the second lifting sensor, it indicates that the overpass roller has been lifted or lowered to perform the patching action, and the number of glass sheets that have passed through the corresponding main line segment stored in the PLC control module is cleared;

[0018] S45: The PLC control module restores the overpass roller to its initial state through the solenoid valve, confirms that it has been restored to its original position according to the signal of the first lifting sensor, and waits for the next round of patching;

[0019] S5: Start a new round of patch counting and judgment.

[0020] Preferably, the patch parameters in S2 include a patch ratio or a fixed time passing a minimum glass sheet threshold.

[0021] Preferably, in order to adapt to the multi-main line segment mode, there is also a transition roller 2 for connecting different overpass rollers, one end of the transition roller 2 is connected to the transition roller 1, and the other end is connected to the overpass roller, and the transition roller 2 can also sense the glass sheet.

[0022] Preferably, when there is more than one glass supply merging system, the corresponding patching parameters also include main line segment selection parameters for patching.

[0023] Preferably, if multiple main line segment patch modes are selected at the same time, and there are more than two main line segments to be supplemented and there is no glass sheet between any two main line segments to be supplemented, the main line segment patch priority increases in the order in which the patch branch line roller passes in the direction of travel.

[0024] Preferably, if multiple main line segment patching modes are selected at the same time, step S44 is performed immediately after S43; if there is only one main line segment, step S44 is performed again when the next patching condition is met after S43 is executed.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] 1. By setting up a patch branch line and intersecting it with the production line after the glass branch lines are combined, the patch branch line is used as a patch reserve to provide a steady supply of glass pieces to each production line, overcoming the problem that the existing patch collection device can only be assembled one-to-one on a single production line when realizing the patch function alone, and requires pre-storage and continuous manual patching.

[0027] By setting up an overpass roller at the intersection, patching can be carried out from the patch branch line to the production line without affecting the normal transmission of the production line. At the same time, setting up a transition roller in front of the overpass roller can reduce the impact of the patching action on the transmission of glass sheets on the patch branch line, thereby improving the transmission efficiency.

[0028] The PLC control module is used for unified intelligent management, and intelligent priority analysis and patching are performed in scenarios where multiple production lines need patching, which significantly improves patching efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Embodiment 1: This embodiment provides a glass production line linkage patch control method, such as Figure 1 As shown, it includes a sensor module 1, a glass supply merging system 2 for collecting and connecting glass sheets of each branch line to the main line, a user control device 3, a patch branch line 4, an operation control component 5 and a PLC control module 6. The PLC control module 6 can control the sensor module 1 and receive its signals; the user control device 3 is connected to the PLC control module 6 and can transmit patch-related parameters; the operation control component 5 controls the operation status of specific equipment under the command of the PLC control module 6; the main line segment 2a after the glass supply merging system 2 is collected has an intersection a with the patch branch line 4, At the intersection a, an overpass roller a1 which can be controlled by the operation control component 5 is provided. The sensor module 1 is installed at the intersection a and is composed of various photoelectric sensors. It can adopt the rising edge trigger mode to transmit signals to the PLC control module 6 when the light signal changes. The PLC control module 6 uses the signal of the sensor module 1 to comprehensively judge whether the main line segment 2a meets the patching conditions set by the user control device 3, and controls the operation control component 5 to complete the action of patching the main line segment 2a from the patch branch line 4 using the overpass roller a1 when the patching conditions are met. The glass supply merging system 2 and the patch branch line 4 both adopt the roller mode transportation commonly used in the industry. Figure 1 As shown, the operation control component 5 includes a frequency converter 5a, which is connected to the transport drive motor on each roller track to control the start and stop of each roller track; the operation control component 5 also includes a solenoid valve 5b for controlling the action of the overpass roller track a1, which controls the cylinder to adjust the rise and fall of the roller track section at the intersection a on the patch branch line 4. All the actions that the PLC control module 6 needs to implement are completed by controlling the operation control component 5.

[0039] like Figure 2As shown, there is a transition roller 41 in front of the patch branch line 4 of the overpass roller a1, which is used to buffer the impact of the interruption of the transportation of the patch branch line 4 caused by the change of the overpass roller a1; the overpass roller a1 adopts the electric drive lifting method of the roller section at the intersection a to switch the transportation line of the roller section at the intersection. In the original state, the main line section 2a and the patch branch line 4 are independent upper and lower rollers, and both are normally transporting glass sheets; when patching, the roller section of the patch branch line 4 at least stops running at the roller section at the intersection a and the transition roller 1, and its roller section at the intersection a is combined into the roller section of the main line section 2a by lifting or lowering, the patch branch line 4 is disconnected, and the patch branch line transition roller 41 is used to buffer the glass sheets; as shown Figure 4 As shown, the overpass roller a1 is provided with a first lifting sensor 1a and a second lifting sensor 1b for detecting the lifting position of the roller section on the side close to the patch branch line 4 and the side close to the main line segment 2a, respectively, to judge the state of the overpass roller a1 during patching. A signal from the first lifting sensor 1a represents that the overpass roller a1 is in the initial state, at which time the upper and lower rollers can operate normally and independently for transmission. When the second lifting sensor 1b has a signal, it indicates that the roller section of the patch branch line 4 at the intersection a has been merged into the roller section of the main line segment 2a, and the transmission of the patch branch line 4 is interrupted.

[0040] like Figure 5 As shown, the specific operation implementation method of the above glass production line linkage patch control system is as follows:

[0041] S1: Power on and initialize the glass supply and merging system 2, and power on the user control device 3, the sensor module 1, and the PLC control module 6;

[0042] S2: The user controls the device 3 to set the mode to the automatic patching state, sets the patching parameters, and generates a patching condition mathematical model according to the patching parameters. At this time, the control component 5 and the patching branch line 4 are powered on and the patching branch line 4 starts to transport the glass sheets.

[0043] S2: The patch parameters include the patch ratio or the fixed time passing the minimum glass slice threshold to determine the patch timing;

[0044] S3: In the automatic state, the first sensor array 12a composed of the first sensor 12a1 and the second sensor 12a2 sends a signal according to the change of light intensity to determine the passing of glass sheets, and feeds it back to the PLC control module 6 to calculate the sum of the number of glass sheets that have passed the current main line segment 2a, store the data and interact with the patch parameters in real time to determine whether the patch conditions are met;

[0045] S4: After the patching condition is met, the PLC control module 6 instructs the operation control component 5 to control the overpass roller a1 to perform the patching action and complete the patching; the sensor module 1 sends a signal, and the number of glass pieces that have passed the corresponding main line segment 2a stored in the PLC control module 6 is reset to zero;

[0046] S5: Start a new round of patch counting and judgment.

[0047] Further, such as Figure 6 As shown, the more specific implementation steps of S4 are:

[0048] S41: confirming, based on the signal of the first lifting sensor 1a, that the flyover roller a1 is in the initial mode of normal operation of the upper and lower rollers;

[0049] S42: The third sensor 141 and the fourth sensor 142 form the second sensor array 14. After the patch requirement is met, it is confirmed that there is no glass sheet at the intersection a of the main line segment 2a according to the signal of the first sensor array 12a, and it is confirmed that there is a glass sheet at the intersection a of the patch branch line 4 according to the signal of the second sensor array 14. The PLC control module 6 uses the inverter 5a to at least stop the operation of the roller and the transition roller 41 of the patch branch line 4 at the intersection a, and at the same time stops the operation of the roller of the main line segment 2a or keeps the roller of the main line segment 2a running, but according to the signal sent by the first sensor array 12a, it is determined to ensure that the glass sheet of the main line segment 2a in front of the entrance of the intersection a along the direction of the roller travel is kept at a safe distance from the intersection a;

[0050] S43: The PLC control module 6 controls the patch branch line 4 through the solenoid valve 5b to carry the glass sheet up or down at the roller section of the intersection a and integrate it into the roller line of the main line section 2a, and starts to transport the glass sheet to the roller line of the main line section 2a;

[0051] S44: The roller section of the patch branch line 4 at the intersection a returns to the initial state; after the PLC control module 6 receives the specific signal from the second lifting sensor 1b, it indicates that the overpass roller a1 has been lifted or lowered to perform the patching action, and the number of glass sheets that have passed the corresponding main line segment 2a stored in the PLC control module 6 is cleared;

[0052] S45: The PLC control module restores the overpass roller a1 to its initial state through the solenoid valve 5b, and confirms that it has been restored to its original state according to the signal of the first lifting sensor 1a. The patch branch line 4 starts to operate normally and waits for the next round of patching.

[0053] After the above S44 is executed, when the next patching condition is met, step S45 is executed again. At this time, when the above patching condition is met, the patch branch line 4 only stops the roller at the intersection a and the transition roller 41 before it, and the remaining roller sections of the patch branch line 4 continue to reduce the speed for a certain period of time, so as to store an appropriate amount of patches on the above transition roller 41 to facilitate more timely patching next time.

[0054] The first sensor array 12a may be: a first sensor 12a1 and a second sensor 12a2 respectively arranged before and after the intersection a of the main line segment 2a, which can determine whether the glass sheet is in a designated area and the position of the glass sheet by detecting changes in light intensity; the second sensor array 14 includes a third sensor 141 and a fourth sensor 142 respectively arranged before and after the intersection a of the patch branch line 4.

[0055] Embodiment 2: The difference from Embodiment 1 is that the present invention is applied to the situation where multiple main line segments 2a need to be patched at the same time.

[0056] like Figure 2-3 As shown, when the number of main line segments 2a is greater than one, that is, there are multiple glass sheet branch lines after the production line is assembled, the patch branch line 4 will have multiple intersections a with the main line segment 2a, and the above patch parameters also include the main line segment 2a selection parameters that need to be patched, that is, confirm the specific main line segment 2a to be patched. At this time, the patch branch line 4 is also provided with a transition roller 42 for connecting different interchange rollers a1. One side of the transition roller 42 is connected to the transition roller 1 41 before the next interchange roller a1 in the running direction of the patch branch line 4, and the other side is connected to the interchange roller a1 before it. The transition roller 1 41 and the transition roller 2 42 can sense the glass sheets respectively to judge the distribution of the glass sheets on the patch branch line 4.

[0057] like Figure 7 As shown, when the PLC control module 6 determines that a main line segment 2a meets the patch requirement, it will determine whether there is a main line segment 2a that needs to be patched at the same time along the transmission direction of the patch branch line 4. If there is, the patch will be given priority to the main line segment 2a behind it to reduce the impact of the patch action interrupting the transmission of the patch branch line 4. Unless the PLC control module 6 determines that there are other glass sheets that can be patched through the sensors on the transition roller 1 41 and the transition roller 2 42 on the patch branch line 4 between the two, the patches can be patched at the same time. In order to prevent the subsequent main line segment 2a patching from being affected by the interruption of the patch branch line 4 transmission due to the action of the overpass roller a1, step S45 is performed immediately after S44 in the multi-line patching mode.

[0058] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0059] Although this article uses more terms such as sensor module 1, glass supply and merging system 2, user control device 3, patch branch line 4, operation control component 5, PLC control module 6, transition roller 1 41, transition roller 2 42, intersection a, first lifting sensor 1a, second lifting sensor 1b, main line section 2a, overpass roller a1, frequency converter 5a, solenoid valve 5b, first sensor array 12a, first sensor 12a1, second sensor 12a2, second sensor array 14, third sensor 141, fourth sensor 142, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
