Technical Field

[0001] The invention relates to the technical field of glass deep processing, and in particular to a method and device for real-time monitoring and slag removal of broken glass. Background Art

[0002] Secondary glass products are deep-processed glass. They use flat glass (float glass, ordinary drawn flat glass, flat-drawn glass, rolled glass) formed once as the basic raw material. According to the use requirements, different processing techniques are used to make glass products with specific functions. During the deep processing of glass, equipment such as tempering furnaces, homogenizing furnaces or wind grids may be used. When these equipment are used for processing, the glass may break and then fall through the gap at the bottom of the equipment. The broken glass needs to be cleaned up in time. The length of large-scale glass production lines can reach tens of meters, which requires high-frequency manual inspections. The workload is large. If broken glass is missed or not found in time, the accumulated glass debris may also cause subsequent glass breakage and damage to the transmission mechanism. However, the industry lacks equipment for cleaning glass debris for long production lines. Summary of the invention

[0005] As a preferred solution, each time the glass conveying machine starts and stops, the horizontal moving distance of any point on its bearing surface is greater than the entire length of the glass conveying machine.

[0006] As a preferred solution, each position of the glass deep processing production line is covered by at least two sound sensors; when the glass is broken, at least two sound sensors detect the sound of the broken glass.

[0007] As a preferred solution, the actual weight of a single piece of glass is detected on the glass deep processing production line, and the actual temperature of a single piece of glass in each section of the glass deep processing production line is detected; If the actual weight of a single piece of glass is greater than a preset weight and / or the actual temperature is greater than a preset temperature, lowering the minimum detection threshold of the sound sensor and / or increasing the acquisition frequency of the sound sensor; If the actual weight of a single piece of glass is less than the preset weight and / or the actual temperature is less than the preset temperature, the minimum detection threshold of the sound sensor is increased and / or the acquisition frequency of the sound sensor is reduced.

[0008] As a preferred solution, glass slag storage bins are provided at both ends of the glass conveying machine; After receiving any trigger signal, the control module determines the position of the broken glass and the distance between the broken glass and the two broken glass storage bins, and controls the glass conveying machinery to drive the broken glass to move horizontally toward the broken glass storage bin with a smaller distance.

[0010] As a preferred solution, glass slag storage bins are provided at both ends of the glass conveying machinery.

[0011] As a preferred solution, it also includes a mounting bracket for mounting the sound sensor and adjusting its position.

[0018] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0019] It should be noted that: unless otherwise defined, the technical terms or scientific terms used in this document shall have the usual meanings understood by people with ordinary skills in the field to which the invention belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express quantity restrictions, but indicate the existence of at least one; the words "first", "second" and "third" used in this document shall not be regarded as restrictions on the order of components, but are only used to distinguish different components; words such as "include" or "comprise" and the like indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0020] In order to more clearly describe the method and device for real-time monitoring and slag removal of broken glass, Figure 1-5 Describe this embodiment: like Figure 1 , Figure 2 and Figure 4 As shown, a method for real-time monitoring and cleaning of broken glass is provided, wherein a plurality of sound sensors 4 are arranged along the glass conveying direction of the glass deep processing production line 1 to form a continuous detection sound range 400 covering the glass deep processing production line 1; The sound sensor 4 detects the glass deep processing production line 1 in the detection sound range 400, and when at least one sound sensor 4 detects the sound of glass breaking, a trigger signal is fed back to the control module 5; The control module 5 receives any trigger signal and starts the glass conveying machine 2 located below the glass deep processing production line 1 once after an interval t, wherein t is the preset time from the glass breaking to the glass conveying machine 2 falling to the glass conveying machine 2; The running distance of the glass conveying machine 2 after one start-up is such that the broken glass carried on the upper part can move horizontally and fall into the broken glass storage bin 3 .

[0021] In the above embodiment, since what is detected is the sound of glass breaking, a time t is set to wait for the broken glass to fall onto the glass conveying machine 2. The t value is preset according to the actual situation, and t≥0. If the glass breaks faster or the temperature is higher, the t value can be adjusted to a smaller value. If the glass breaks slower or the temperature is lower, the t value can be adjusted to a smaller value.

[0022] In the above embodiment, each time the glass conveying machine 2 starts and stops, the horizontal movement distance of any point on its bearing surface is greater than the overall length of the glass conveying machine 2. The glass conveying machine 2 can be a belt conveyor that can transmit in both directions. Each time the glass conveying machine 2 is started, it is ensured that the broken glass 7 at any position on its upper bearing surface can be moved to the glass slag storage bin 3.

[0023] Detection range 400 Figure 2 As shown, the entire glass deep processing production line 1 is completely covered, and the position arrangement of the sound sensor 4 is relatively flexible, and it only needs to not affect the falling of broken glass; the sound sensor 4 can directly capture the environmental decibel value when in use, and if the decibel value exceeds the threshold, it is directly fed back to the PLC digital quantity, or the sound signal is transmitted to the host computer through the PLC, and the host computer performs filtering, and the data is analyzed to determine whether there is glass breakage, and then the action of the glass conveying machine 2 is controlled by the PLC; In order to facilitate the determination of the location of glass breakage, each location of the deep processing production line 1 is covered by at least two sound sensors 4. When the glass breaks, at least two sound sensors 4 are used to detect the sound of glass breakage. Each sound sensor 4 is set according to a certain rule or sequence and is numbered. When a single sound sensor 4 is triggered, the location of glass breakage can be determined accordingly; when two sound sensors 4 are triggered at the same time, a more accurate location can also be calculated through the binaural effect.

[0024] See also Figure 5 , when inspecting the glass deep processing production line 1, the size of a single glass can be detected by a scanner 8, a light eye and other equipment and its actual weight can be calculated, and / or the actual temperature of a single glass in each section (a1, a2, a3...) of the glass deep processing production line 1 can be detected by a temperature probe 9 and other equipment. The position attribute of the sound sensor is adjusted according to the weight and temperature of the glass, and the power consumption and response speed are balanced. When the glass weight is large and the temperature is high, the burden on the glass conveying machine 2 is large, and a quick response is required to timely deliver the broken glass 7 into the broken glass storage bin 3. The specific control method is as follows: If at least one of the two situations occurs that the actual weight of a single piece of glass is greater than the preset weight and the actual temperature is greater than the preset temperature, the measures that can be taken are: lowering the minimum detection threshold of the sound sensor 4, increasing the acquisition frequency of the sound sensor 4, at least one of the two methods, or taking both simultaneously; wherein the detection threshold at least includes the minimum detection threshold, and the lower the minimum detection threshold, the higher the sensitivity of the sound sensor 4 being triggered; If at least one of the two situations occurs, that is, the actual weight of a single piece of glass is less than the preset weight and the actual temperature is less than the preset temperature, the measures that can be taken are: increasing the minimum detection threshold of the sound sensor 4, reducing the acquisition frequency of the sound sensor 4, at least one of the two methods, or both methods are taken simultaneously.

[0025] See also Figure 4In order to ensure that the high-temperature broken glass 7 can escape from the glass conveying machine 2 along the shortest path, broken glass storage bins 3 are set at both ends of the glass conveying machine 2. After receiving any trigger signal, the control module 5 determines the position of the broken glass and the distance between the broken glass and the two broken glass storage bins 3, and controls the glass conveying machine 2 to drive the broken glass to move horizontally toward the broken glass storage bin 3 with a smaller distance. The serial number of the triggered sound sensor 4 and the length of the deep processing production line 1 are known, and the distances SL and SR from the falling position of the broken glass (or the triggered sensor) to the two broken glass storage bins 3 can be calculated. In the case shown in the figure, SL < SR, so the glass conveying machine 2 is controlled to run counterclockwise to make the broken glass move horizontally toward the broken glass storage bin 3 on the left, ensuring that the broken glass is collected as soon as possible.

[0026] A device for real-time monitoring and cleaning of broken glass: A glass conveying machine 2 is provided below the glass deep processing production line 1 for receiving broken glass dropped from the glass deep processing production line 1 and driving the broken glass to be transferred horizontally; A glass slag storage bin 3 for collecting broken glass dropped from the glass conveying machine 2 is provided below the end of the glass conveying machine 2; two glass slag storage bins 3 can be provided, one at each end of the glass conveying machine 2; Multiple sound sensors 4 are arranged at intervals along the glass conveying direction. The multiple sound sensors 4 form a continuous detection sound range that covers the glass deep processing production line 1. The coverage areas of two adjacent sound sensors 4 overlap by at least half, and are used to detect and judge the sound of glass breaking and output a trigger signal. It also includes a control module 5 located outside the glass deep processing production line 1, which is used to control the glass conveying machine 2 to start after receiving a trigger signal, and to horizontally move the broken glass dropped on the glass conveying machine 2 to the glass broken slag storage bin 3 and then close the glass conveying machine 2. The control module may specifically include a PLC and a host computer, and the PLC is used to receive analog or digital signals of sound and control the start and stop of the glass conveying machine 2, and the host computer is used to receive signals from the PLC, filter and perform data analysis on the signals, and feed back control signals to the PLC.

[0027] It also includes a mounting bracket for mounting the sound sensor 4 and adjusting its position.

[0028] A scanner 8 is arranged on the outside of the glass deep processing production line 1 for detecting the size of a single piece of glass, so as to calculate the actual weight of the glass based on the size information. Temperature probes 9 distributed at intervals are also arranged on the glass deep processing production line 1 for detecting the actual temperature of the glass on the glass deep processing production line 1.
