Description

Technical Field

[0001] The present invention belongs to the technical field of glass manufacturing, and particularly relates to a post-treatment device for glass substrates. Background Art

[0002] The production process of glass substrates mainly includes two post-treatment stages: the front treatment stage mainly includes raw material preparation, melting and forming, and cutting and edging; the post-treatment stage mainly includes polishing and cleaning. Polishing is mainly to finely process the surface of the glass substrate to make the surface of the glass substrate reach a high smoothness to ensure the optical properties and appearance quality of subsequent glass products, etc. After the glass substrate is polished, cleaning is an essential step. Cleaning is to remove various pollutants remaining on the surface of the glass substrate during the production process, such as polishing agents, oil stains, and dust, etc. After the cleaning is completed, it is generally also necessary to dry the glass substrate to remove the water stains remaining on the surface of the glass substrate after cleaning, so as to be packed and shipped or to further process the glass substrate, such as coating and printing, etc.

[0003] The device for post-treating glass substrates generally consists of a conveyor and post-treatment equipment such as polishing and cleaning equipment arranged on the conveying path of the conveyor. For example, the glass sheet high-efficiency cleaning and drying device disclosed in Chinese Patent CN210253462U, and a glass cleaning machine disclosed in Chinese Patent CN203044457U. Under the existing treatment environment and conditions, some glass substrates will be broken and damaged during the polishing and cleaning processes. Currently, during the post-treatment of glass substrates, it is mostly manual to pick up and place the glass substrates beside the conveyor and count the quantity, so as to orderly process the glass substrates and count the breakage rate and achievement rate of the post-treatment of the glass substrates. This not only has a large labor intensity, low efficiency, but also is prone to errors in manual counting. Although there are also cleaning and drying equipment that can automatically count at present, it can only detect and count the number of passing items, and cannot separately count the number of intact glass substrates before and after treatment. Part of the counting work still needs to be completed manually, and there is a lack of centralized recycling and treatment of broken glass. Therefore, aiming at the current situation of large labor intensity and easy errors in manual counting during the post-treatment of glass substrates, it is necessary to design a post-treatment device for glass substrates that can automatically count, so as to reduce the manual labor intensity and improve the counting accuracy. Summary of the Invention

[0012] Further, the material - distributing conveying section adopts roller conveying, and transfers the broken glass formed by the breakage of the glass sheet on the conveyor downward through the gaps between adjacent rollers.

[0013] Further, a receiving trough is arranged directly opposite below the material - distributing conveying section to collect the broken glass falling from the material - distributing conveying section.

[0014] Further, the conveyor has one or more material - distributing conveying sections. The gaps between adjacent rollers on the same material - distributing conveying section are equal, and the gaps between adjacent rollers on each material - distributing conveying section increase sequentially from front to back. Receiving troughs are respectively arranged directly opposite below each material - distributing conveying section to respectively collect broken glass of various sizes.

[0015] Furthermore, the conveyor has two material-dividing and conveying sections, and receiving troughs are respectively provided below the two material-dividing and conveying sections for collecting granular broken glass and block broken glass respectively. The bottom surface of the receiving trough at the front is lower than the bottom surface of the receiving trough at the rear, so as to regularize the granular broken glass and maintain the integrity of the block broken glass.

[0016] Furthermore, the post-processing equipment includes a polishing machine, a cleaning machine and a drying machine which are arranged in sequence from front to back on the conveyor.

Detailed implementation manners

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Embodiment: Please refer to Figure 1 and Figure 5 A glass sheet post-treatment device includes a conveyor 1 and a post-treatment device 2 arranged on the conveying path of the conveyor 1. The post-treatment device 2 includes a polishing machine 17, a cleaning machine 18, and a drying machine 19 arranged in sequence from front to back on the conveyor 1. On the conveying path of the conveyor 1, induction counting devices 3 are respectively arranged on the front side and the rear side of the post-treatment device 2 to respectively detect and count the number of glass sheets entering and leaving the post-treatment device 2. The conveyor 1 has a material distribution and conveying section between the induction counting device 3 on the rear side and the post-treatment device 2, so as to transfer the broken glass formed by the breakage of the glass sheet on the conveying path through manual, mechanical equipment, or the structure of the material distribution and conveying section.

[0023] In the glass sheet post-treatment device of the present invention, by respectively arranging induction counting devices 3 on the front and rear sides of the post-treatment device 2 to respectively detect and count the number of glass sheets entering and leaving the post-treatment device 2, using the induction counting device 3 to detect and count instead of manual counting is beneficial to reducing the labor intensity and counting difficulty and improving the counting accuracy; by arranging a material distribution and conveying section between the post-treatment device 2 and the induction counting device 3 on the rear side, so as to transfer the broken glass formed by the breakage of the glass sheet during post-treatment before reaching the induction counting device 3 on the rear side, thereby avoiding interference with the detection and counting of the induction counting device 3 on the rear side and ensuring the accuracy of the induction counting device 3 in detecting and counting the number of glass sheets, so as to calculate the breakage rate and achievement rate of post-treatment according to the number of front and rear glass sheets; therefore, the glass sheet post-treatment device of the present invention can effectively solve the problems of difficult counting and easy error during the current post-treatment of glass sheets, which is beneficial to reducing the manual labor intensity and improving the counting accuracy.

[0024] During implementation, the induction counting device 3 can use ultrasonic sensors, laser sensors, vision sensors or optoelectronic switches 6 to detect the raw glass sheets, and cooperate with components or devices with counting functions (such as computers, single-chip microcontrollers and PLCs, etc.) to complete the counting of the raw glass sheets; please refer to Figure 1 and Figure 2 , in this embodiment, the induction counting device 3 includes an optoelectronic switch 6 and a counter 7. The sensing end of the optoelectronic switch 6 is set facing the conveyor 1 and can be triggered by the raw glass sheets on the conveyor 1. The counter 7 is electrically connected to the optoelectronic switch 6 and counts the number of trigger times of the optoelectronic switch 6 to realize the detection and counting of the number of raw glass sheets entering and leaving the post-treatment device 2; the present invention uses a combination of an optoelectronic switch 6 and a counter 7 to form the induction counting device 3. The optoelectronic switch 6 is relatively cheaper compared to ultrasonic sensors, laser sensors and vision sensors, which is beneficial to reducing the cost of the raw glass sheet post-treatment device and improving the practicability.

[0025] During implementation, the optoelectronic switch 6 can be a laser optoelectronic switch 6, an ultraviolet optoelectronic switch 6 or an infrared optoelectronic switch 6. Considering that laser optoelectronic switches 6 and ultraviolet optoelectronic switches 6 are not only relatively expensive, but also laser optoelectronic switches 6 are easy to cause harm to the human eye. When staff take and place raw glass sheets and perform related operations beside, protective measures such as wearing goggles are also required; therefore, the present invention selects an infrared optoelectronic switch 6 to detect the raw glass sheets. The infrared optoelectronic switch 6 is not only relatively cheap, but also not easily affected by environmental light, which is beneficial to reducing the cost of the raw glass sheet post-treatment device, improving the environmental adaptability and the accuracy of counting.

[0026] In actual production, to improve production efficiency and rationally utilize production resources, generally, according to the width of the conveyor 1 and the size of the raw glass sheets, multiple raw glass sheets are placed side by side on the conveyor 1 for post-treatment at the same time. In this embodiment, when the conveyor 1 is running, four raw glass sheets are placed side by side for post-treatment at the same time. Therefore, to ensure the accuracy and effectiveness of counting, please refer to Figure 1 、 Figure 2 and Figure 4, in this embodiment, it is selected that on the conveying path of the conveyor 1, four induction counting devices 3 are respectively arranged on the front side and the rear side of the post-treatment device 2. The photoelectric switches 6 on the same side of the post-treatment device 2 are vertically arranged and distributed along the width direction of the conveyor 1. And in the width direction of the conveyor 1, the photoelectric switches 6 of the four induction counting devices 3 correspond one by one to the positions of the four glass substrates arranged side by side on the conveyor 1. In this way, a beam of light signal is emitted by the photoelectric switch 6. After the light signal is reflected and folded back by the glass substrate directly opposite to the photoelectric switch 6, it is received by the photoelectric switch 6 again. The photoelectric switch 6 sends a signal to the counter 7 to complete the counting. Since the glass substrate has a certain size and weight, and the acting force between the glass substrate and the post-treatment device 2 and the conveyor 1 is mainly in the length direction of the conveyor 1, the glass substrates still remain arranged side by side after post-treatment. Thus, the four induction counting devices 3 on the same side can respectively count the glass substrates undergoing post-treatment in four columns on the conveyor 1 at the same time, and the counting of the four induction counting devices 3 does not interfere with each other. During implementation, the counting result on the counter 7 can be read and statistically calculated manually, and the breakage rate and achievement rate of the post-treatment can be calculated according to the total number of glass substrates before post-treatment and the total number of glass substrates after post-treatment. Or the counters 7 can be directly electrically connected to a computer, so that the counters 7 transmit the counting result to the computer, and the computer program calculates the breakage rate and achievement rate of the post-treatment according to the total number of glass substrates before post-treatment and the total number of glass substrates after post-treatment.

[0027] Please refer to Figure 1 and Figure 4 , on the conveying path of the conveyor 1, mounting rods 8 extending along the width direction of the conveyor 1 are respectively fixedly arranged on the front side and the rear side of the post-treatment device 2. The photoelectric switches 6 on the corresponding side are detachably arranged on the corresponding mounting rods 8 through L-shaped brackets 9. Specifically, the front mounting rod 8 is connected below the frame 20 of the conveyor 1, and the rear mounting rod 8 is located above the frame 20 and its two ends are bent and extended towards the conveyor 1 and fixedly connected to the frame 20. The photoelectric switch 6 passes through the mounting hole on the L-shaped bracket 9 and is clamped and fixed up and down by nuts, which is simple for installation and replacement.

[0028] Please refer to Figure 2 and Figure 4 , the counter 7 has a display screen 10 for displaying the number of times the triggered photoelectric switch 6 is counted. In this way, the counter 7 displays the counted value through the display screen 10, so as to facilitate the staff to statistically calculate and master the operating condition of the glass substrate post-treatment device in real time.

[0029] Please refer to Figure 2 and Figure 4On the conveying path of the conveyor 1, support rods 11 are fixedly provided on the front and rear sides of the post-processing device 2, respectively, and the counter 7 is arranged on the support rods 11. In this embodiment, the display screen 10 of the counter 7 is arranged in a direction away from the post-processing device 2; in this way, it is convenient for the staff at the front and rear ends of the conveyor 1 to view the count value. Specifically, the support rod 11 is L-shaped and one end extends vertically and is fixedly connected to the frame 20 of the conveyor 1. The counter 7 is arranged on the transverse rod section of the support rod 11, and the display screen 10 of the counter 7 is arranged in a direction away from the post-processing device 2.

[0030] During implementation, the broken glass on the conveyor 1 can be transferred in advance in the material distribution section by manual operation, but this is not only labor-intensive, but also may be missed, which easily affects the accuracy of counting. Alternatively, the broken glass on the conveyor 1 can be transferred in advance in the material distribution section by mechanical grippers in combination with a visual recognition system, but this is not only costly, but also difficult to ensure reliability. Therefore, please refer to Figure 1 and Figure 5 In this embodiment, the material distribution and conveying section adopts rollers 12 for conveying, and transfers the broken glass formed by the broken glass original piece on the conveyor 1 downward through the gaps between adjacent rollers 12; thus, the material distribution and conveying section designed by the present invention adopts rollers 12 for conveying and transfers the broken glass downward through the gaps between adjacent rollers 12, which reduces the labor intensity and cost and has good reliability; specifically, the rollers 12 on the material distribution and conveying section are distributed at equal intervals. In order to enable the material distribution and conveying section to smoothly convey the glass original piece, the sum of the center distances between any roller 12 on the material distribution and conveying section and the adjacent rollers 12 on both sides should be set to be smaller than the size of the glass original piece in the length direction of the material distribution and conveying section. In order to ensure that all broken glass can fall from the material distribution and conveying section, the sum of the center distances between at least one roller 12 on the material distribution and conveying section and the adjacent rollers 12 on both sides should be set to be close to the size of the glass original piece in the length direction of the material distribution and conveying section.

[0031] See also Figure 1 and Figure 3 , a receiving trough is provided directly below the material distribution conveying section to collect the broken glass falling from the material distribution conveying section; in this way, a receiving trough is provided below the material distribution conveying section to receive the broken glass that falls, so as to uniformly collect the broken glass and transfer the broken glass for recycling and reuse; in addition, since the broken glass is generated during the post-processing process, in order to prevent the broken glass from falling before the receiving trough, a conveying section of the conveyor 1 that is transported by a belt 13 should be provided to pass through the post-processing equipment 2 and connect with the material distribution conveying section; in this embodiment, a support plate 16 fixedly connected to the frame 20 of the conveyor 1 is provided horizontally below the material distribution conveying section, and the receiving trough can be slidably arranged on the support plate 16, and the receiving trough can be slidably pulled out along the width direction of the conveyor 1 to facilitate the transfer of the broken glass.

[0032] During implementation, one or more material-dividing conveying sections may be provided on the conveyor 1, and the gaps between adjacent rollers 12 on the same material-dividing conveying section are equal, and the gaps between adjacent rollers 12 on each material-dividing conveying section increase from the front to the back in sequence, and a receiving trough is provided directly opposite to each material-dividing conveying section below, so as to collect broken glass of various sizes respectively; in this way, broken glass of different sizes falls into different receiving troughs from the material-dividing conveying sections with different gaps between the rollers 12, so as to adopt different recycling methods according to the size difference of broken glass, which is conducive to improving the recycling effect of broken glass; in view of the fact that there are currently two main methods for recycling broken glass, one is to crush and remelt broken glass of smaller size, and the other is to cut off the broken corners and broken edges of broken glass of larger size and higher integrity for other purposes, for this purpose, please refer to Figure 5 In this embodiment, two material distribution and conveying sections are provided, which are the first material distribution and conveying section 4 and the second material distribution and conveying section 5 from front to back, and the first material receiving trough 14 and the second material receiving trough 15 are provided at the bottom. It is used to collect granular broken glass and block broken glass respectively. The bottom surface of the receiving trough at the front is lower than the bottom surface of the receiving trough at the rear. In this way, when the granular broken glass falls from the first material distribution and conveying section 4 into the first material receiving trough 14, the larger height difference can be used to further break up some broken glass with larger particle sizes, so as to regularize the granular broken glass, make the particle size more uniform and meet the remelting requirements. When the block broken glass falls from the second material distribution and conveying section 5 into the second material receiving trough 15, due to the smaller height difference, the integrity of the block broken glass can be better maintained for further cutting and utilization.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
