Description

Technical Field

[0001] The invention belongs to the field of glass processing, and in particular relates to a glass production line and a production method. Background Art

[0002] With the rapid development of the economy and the improvement of living standards, the quantity and quality requirements for processing optical thick glass will continue to increase. Glass cutting and breaking is one of the most important links in the glass processing process, which has been restricting the development of the glass industry for many years. In the past, glass was broken after manual cutting and marking. The manual cutting was uneven and the cross-sectional gradient could not be controlled. As a result, many workers had to use backward tools such as axes and hammers to knock off excess corners, which was not only inefficient but also had poor quality. In addition, the broken glass slag and sharp corners harmed the workers, which greatly reduced efficiency. Especially for thick glass, when using manual cutting and breaking, there are difficulties such as large gradient of cutting and breaking cross-sectional, high glass loss, and low efficiency of manual weighing and stacking. In addition, traditional operations of cutting, labeling, and stacking are messy single-station operations, which are equivalent to "stall" operations, with long logistics routes, which greatly affects production efficiency.

[0003] Overall, the existing glass processing companies in China have backward production technology and equipment, most of them are small-scale, and their production efficiency and quality are not guaranteed. They are in urgent need of using advanced technology and equipment to build intelligent production lines of a reasonable scale, improve production efficiency, ensure production quality, and achieve the goal of advanced technology and equipment and large-scale production. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology and provide an intelligent production line and a method for cutting and stacking of glass automatically with high production efficiency and guaranteed product quality.

[0005] In order to solve the above technical problems, the technical solution proposed by the present invention is:

[0006] An intelligent production line for automatic cutting and palletizing of glass includes a roller conveyor line, a cutting device, a breaking device, a weighing device, a labeling device and a palletizing device, wherein the cutting device, the breaking device, the weighing device, the labeling device and the palletizing device are arranged in sequence from upstream to downstream along the material flow direction of the roller conveyor line. Each mechanism uses a positioning pin or a positioning groove to ensure the relative position, which well ensures the accuracy.

[0007] The material flow direction can be a spiral flow direction, or an overlapping flow direction with staggered levels. Specifically, it can be a spiral square, a spiral circle, a spiral cone, etc. Compared with the unidirectional flow direction that is spread out in sequence, the roller conveyor line, the cutting device, the breaking device, the weighing device, the labeling device and the stacking device disclosed in the present invention are arranged in a compact spiral shape, so that the material flow direction is a spiral square or spiral circle flow direction, so that the glass production line is compressed and integrated in a smaller space, and compared with the unidirectional linear arrangement, it saves more cutting space for the automated glass line.

[0008] With staggered overlapping flow directions, the roller conveyor line, cutting device, breaking device, weighing device, labeling device and palletizing device are arranged in a circuitous manner. Compared with the one-way linear arrangement, it saves more cutting space for the automated glass line.

[0009] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, the cutting device includes a support seat, a tool, a first driving mechanism for driving the tool to move along the X-axis, Y-axis, and Z-axis, and a lower pressure wheel assembly for pressing down on the glass surface when the tool cuts the glass. The support seat is mounted on the upper end of the roller conveyor line, and the tool is arranged on the first driving mechanism. The lower pressure wheel assembly includes a pressure wheel and a second driving mechanism for driving the pressure wheel to move up and down. The above-mentioned first driving mechanism can adopt a guide rail structure (high-precision servo three-axis module) arranged along the X-axis, Y-axis, and Z-axis, which can realize the precise adjustment of the tool moving track. The above-mentioned second driving mechanism can adopt a cylinder to drive the pressure wheel to move up and down. When cutting is required, the proximity switch at the blocker detects that the glass is in place, and the lower pressure group assembly moves downward to press the glass. The tool is driven by the first driving mechanism to cut scratches at a specified position on the glass surface, which is convenient for subsequent breaking. After cutting, the tool and the pressure wheel return to their positions driven by the first driving mechanism and the second driving mechanism respectively.

[0010] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, a pair of lower pressure wheel assemblies are provided, which are respectively located on both sides of the support seat, and the first driving mechanism is arranged between the pair of lower pressure wheel assemblies. A pair of lower pressure wheel assemblies are provided, which are respectively located on both sides of the first driving mechanism, that is, on both sides of the tool, so that the glass is pressed tightly at the front and rear ends of the tool, and the glass will not move when the tool is cutting, which is conducive to the accurate cutting of the tool. The above-mentioned pair of lower pressure wheel assemblies are respectively arranged above the roller conveyor line, and are arranged upstream and downstream.

[0011] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, an air-blowing slag removal device is also installed at the tool, and the air-blowing slag removal device includes a compressed air blowing outlet, and the compressed air blowing outlet is aimed at the cutting position of the cutting device. During cutting, a lot of fine glass slag will remain on the diamond tool, which will affect the cutting effect over time. The present invention uses an air-blowing slag removal device to spray compressed air to remove the fine glass slag. At the same time, the compressed air can blow out gas for cooling the tool.

[0012] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, the breaking device includes a push rod, a mounting seat, a buffer guide rod and a third driving mechanism for driving the push rod to move up and down, the mounting seat is arranged below the roller conveyor line, the push rod is movably arranged on the mounting seat through the buffer guide rod, and the third driving mechanism is connected to the push rod. When it is necessary to break the glass, the push rod moves upward and lifts, and at this time the push rod moves upward to above the roller conveyor line. When it is not necessary to break the glass, the push rod returns to its position, and at this time the push rod is located below the roller conveyor line. The above-mentioned third driving mechanism can use an adjustable stroke cylinder to drive the push rod to move up and down. The above-mentioned buffer guide rod may include a guide rod and a spring, which plays a buffering role to avoid damaging the glass. When it is necessary to break, the proximity switch at the blocker detects that the glass is in place, the lower pressure wheel assembly is pressed down to prevent the glass from running, and the adjustable stroke cylinder drives the push rod upward to realize the lifting action, and the glass is broken into fixed-size glass pieces along the cutting seam.

[0013] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, a pair of pressure wheels in the lower pressure wheel assembly close to the breaking device are provided, which are arranged in sequence forward and backward along the material flow of the roller conveyor line, and the push rod is arranged between the pair of pressure wheels. In addition to cooperating with the cutting device, the above-mentioned lower pressure wheel assembly can also cooperate with the breaking device to achieve the breaking of glass. At this time, the push rod is located below the pair of pressure wheels. When the glass needs to be broken, the pair of pressure wheels moves downward to press the glass, and the push rod moves upward to break the glass. This method is equivalent to providing pressure wheels on the front and rear sides of the push rod, which is conducive to improving the breaking stability.

[0014] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, the weighing device includes an adsorption plate, a support plate, a weighing sensor and a fourth driving mechanism for driving the adsorption plate to move up and down, the adsorption plate is arranged on the fourth driving mechanism, the fourth driving mechanism is arranged on the support plate, the support plate is arranged on the weighing sensor, and the width of the adsorption plate is smaller than the spacing between adjacent rollers in the roller conveyor line. When it is necessary to weigh the glass, the adsorption plate moves upward and lifts up, at which time the adsorption plate moves upward to above the roller conveyor line, and when it is not necessary to weigh the glass, the adsorption plate returns to its position, at which time the adsorption plate is located below the roller conveyor line. The above-mentioned fourth driving mechanism can be a cylinder. When weighing is required, the proximity switch at the blocker detects that the glass is in place, and the cylinder drives the adsorption plate to separate the glass block and the roller line for weighing, thereby realizing online weighing.

[0015] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, the labeling device is a cylinder push-pull labeling device. The labeling adopts a cylinder push-pull labeling device, which is suitable for labeling the front, side and back of the product, and is widely used for labeling of products in static and moving states. There are differences between the front and back of the glass. In order not to affect the subsequent processing technology, the present invention adopts an automatic labeling method for the back.

[0016] In the above-mentioned intelligent production line for automatic cutting and stacking of glass, preferably, the stacking device includes a gantry truss manipulator, a paper pad device and a storage mobile cart. The gantry truss manipulator includes three axes, X, Y, and Z, which are used to absorb a single piece of corrugated paper in the paper pad device and place it on the glass surface and for the transportation and stacking of glass to the storage mobile cart. In order to prevent physical damage to the glass, a layer of buffer corrugated paper needs to be placed between the glasses. The gantry truss manipulator includes three axes, X, Y, and Z, which can realize the stacking and transportation of glass blocks. The first and third pieces of glass are taken out every even hours and grabbed to the random inspection safety window. A tray is set on the storage mobile cart, and a one-standby-one-use mode can be adopted. The storage mobile cart is positioned by a positioning mechanism on the ground. The gantry rack manipulator stacks the glass blocks neatly as required. When stacking, the gantry rack manipulator must absorb the buffer corrugated paper and place it between adjacent glasses.

[0017] The above-mentioned intelligent production line for automatic cutting and stacking of glass preferably also includes components such as fences and sampling windows, and the sampling window can be provided with a roller conveyor line.

[0018] As a general technical concept, the present invention also provides a method for cutting and stacking glass using the above-mentioned intelligent production line for automatic cutting and stacking of glass, comprising the following steps:

[0019] S1: The glass is discharged from the annealing furnace and sent to the roller conveyor line;

[0020] S2: When the glass is delivered to the cutting device by the roller conveyor line, the cutting device cuts and scratches the surface of the glass to facilitate subsequent breaking by the breaking device;

[0021] S3: When the glass is delivered to the breaking device by the roller conveyor line, the breaking device breaks the glass at the cutting mark;

[0022] S4: The broken glass is sent to the weighing device by the roller conveyor line to weigh the glass;

[0023] S5: The qualified glass is sent to the labeling device by the roller conveyor line for labeling;

[0024] S6: The labeled glass is collected by the palletizing device and stacked into stacks, thus completing the automatic cutting and palletizing of the glass.

[0025] In the above method, preferably, a blocker and a mirror-reflecting photoelectric switch are installed on the roller conveyor line, and an encoder is installed on the cutting device. The blocker and the encoder are combined with the speed and time of the roller conveyor line to automatically calculate the length of the glass, and cut scratches on the glass surface according to the length data. In the present invention, the encoder and the wheel are connected to the same transmission shaft, and the distance from the center of the pressure wheel to the blocker is manually measured to facilitate error elimination. The glass is limited by the blocker, and the signal is converted from the rotary motion to the straight line length by the encoder, and the PLC intelligently calculates and determines the length of the cut glass. For the encoder, its accuracy is much higher than that of the proximity switch, and the encoder has a lot of pulses in one circle, such as 2000, so the resolution is 0.005mm per pulse. Then, the next task is to collect the number of pulses of the encoder × resolution, which is the moving distance. Through the cooperation of the encoder and the sensor according to the belt conveying speed and time, the cutting length can be intelligently calculated, which can well solve the problem of non-stop follow-up cutting of the glass belt coming out of the front-end annealing kiln, ensuring that the product processing meets the standards.

[0026] The intelligent production line for automatic glass cutting and stacking of the present invention includes a cutting device, a breaking device, a weighing device, a labeling device, a stacking device, a protective fence and other components. These devices cooperate with each other and are connected in series to form an automated production line equipment. It adopts a controllable and programmable PLC program for automatic control to achieve automatic cutting and breaking with neat cross-sections, online weighing, online labeling, gantry truss manipulators cooperating with storage mobile carts for automatic stacking and other intelligent production. The production process is as follows: glass cutting, glass breaking, glass weighing, reverse labeling, paper padding stacking, and finished product caching. It has obvious advantages such as simple operation, reliable operation, high processing quality and intelligent production capacity statistics, which greatly improves processing efficiency and product quality. The workflow of the above-mentioned production line, the specific working principles of each component and the effect analysis are as follows:

[0027] The glass ribbon is fed in strip form from the front glass forming line (annealing furnace) and enters the roller conveyor line. Since the glass forming state is not always square, sometimes there will be obvious bumps on the surface, or defects such as horizontal and vertical cracks (horizontal and vertical cracks in the broken section of the glass), which are removed by manual intervention.

[0028] When the glass is delivered to the cutting device by the roller conveyor line, the equipment can continue to follow the operation without stopping. The blocker and encoder automatically calculate the length of the glass (the blocker senses that the glass belt is in place, and the lower pressure wheel assembly is pressed down and compacted. Through the cooperation of the encoder and the blocker, the cutting length can be intelligently calculated according to the roller conveying speed and time). This can well solve the problem of non-stop follow-up cutting of the glass belt coming out of the front-end annealing furnace, ensuring that the product processing meets the standards. The tool installed at the end of the high-precision servo three-axis module tracks the upper surface of the glass belt according to the real-time position feedback from the encoder, and performs fixed-length and fixed-depth cutting. The diamond cutter wheel cuts scratches on the glass to facilitate subsequent breaking. The scratch depth is determined according to the thickness of the glass (the production line comes with a data analysis library, which determines the scratch depth of a certain type of glass according to the thickness of the glass to ensure that the glass block does not break or explode to produce cross-sectional defects). The diamond cutter wheel will be worn out after a period of use, and the distance the diamond cutter wheel descends needs to be adjusted. After the wear is too serious, it needs to be replaced regularly. The diamond cutter wheel of the cutting device of the present invention is very convenient to replace and adjust, and it is convenient to compensate for the wear of the diamond cutter wheel. The cutting device of the present invention repeatedly considers the compensation adjustment and replacement of the consumables (adjusting parameters according to the wear of the tool, the cutting depth of the cutting tool, that is, the moving distance of the tool Z axis).

[0029] After the cutter has carved a mark on the glass belt, when the glass is sent to the breaking device by the roller conveyor line, the pressure wheel presses the glass on the roller conveyor line from above, and the push rod automatically rises to realize the lifting action. When subjected to the upward breaking force, due to the stress concentration, a large stress will be generated at the crack tip and break, and the length of the glass block will automatically break (the upper pressure wheel presses the glass down on the roller conveyor line, and the cylinder of the breaking device rises to break the glass, and the stress is about 80MPa). The breaking device is equipped with a spring buffer to avoid damaging the glass block. The adjustable stroke cylinder adjusts the breaking stroke according to the different glass thicknesses to meet the production needs of various thicknesses of glass. The unique floating design of the breaking device (there is a buffer spring on the breaking device, which has a certain up and down floating function) intelligently judges the breaking force according to the thickness, while ensuring the processing efficiency and processing effect, ensuring that the cross-sectional gradient is small and flat to meet the requirements, and ensuring the quality of glass unloading.

[0030] When the broken glass is sent to the weighing device by the roller conveyor line, the glass will be weighed. The weighing device is weighed by a 0-24mA current sensor, with a repeatability of ≤±0.025%FS (repeatability: ±0.2%FS, "repeatability" refers to the consistency between the measurement results when the instrument measures the same object multiple times under the same measurement conditions. Here, "±0.2%FS" means that the maximum deviation between the measurement results of the instrument will not exceed 0.2% of the full scale (FS, the abbreviation of Full Scale), and the full scale refers to the maximum value that the instrument can measure). The weighing accuracy is high. Due to the use of online weighing, the accuracy must be guaranteed by separating the glass piece from the roller conveyor line. The cylinder with tooling uses vacuum to absorb the glass. The cylinder lifts the glass block to a certain height, completely separating it from the roller conveyor line, and then automatically weighs it, which greatly improves the weighing accuracy (if the glass is weighed without separating it from the roller conveyor line, the accuracy will be disturbed. The lifting separation line body is a single body and will not have any impact).

[0031] The qualified glass is sent to the labeling device by the roller conveyor line for labeling. The labeling device adopts cylinder push-pull labeling, which is suitable for labeling the front, side and back of the product and is widely used for labeling of static and moving products. There are differences between the front and back of the glass. In order not to affect the subsequent processing technology, the present invention can adopt the automatic labeling method of the back. The operator conducts regular sampling, and the unqualified products are automatically released and conveyed to the NG roller line for buffer screening.

[0032] The labeled glass is collected by the palletizing device and stacked into stacks. During the palletizing process, a layer of buffer corrugated paper is placed between the glass to prevent physical damage to the glass. The corrugated paper stack is manually unloaded, and the gantry truss robot automatically places a single piece of corrugated paper on the glass surface. The paper pad device uses a servo feeding device to automatically feed, which greatly improves production efficiency. The gantry truss robot consists of three axes, X, Y, and Z, which can realize the palletizing and transportation of glass blocks. Every even hour, the first and third pieces of glass are taken out and grabbed to the safety window for manual sampling. The storage mobile cart adopts a one-standby-one mode (one set is used for the machine and one set is used on standby to reduce logistics turnover time). The storage mobile cart is positioned by the positioning mechanism on the ground, and the gantry rack robot stacks the glass blocks neatly as required.

[0033] The present invention perfectly combines the equipment with the carrier for storage and transportation. The design not only meets the storage requirements, but also facilitates the rapid positioning and separation of the storage mobile cart. The production line adopts a linear layout, and the truss manipulator loads and unloads materials. There is also manual intervention and incoming material screening. The glass is rotated and conveyed by the roller conveyor line to move forward, passing through multiple stations in sequence. The diamond cutter wheel scratches the glass, the breaking device cooperates with the double-row pressure rollers to break the glass, the high-precision weighing sensor of the weighing device weighs online, the labeling device labels by its own weight, and the stacking device automatically collects and stacks. This method has a simple, stable and low-cost structure, and the glass processing efficiency is very high, achieving the effect of high-quality, efficient and stable production of glass unloading.

[0034] In the cutting and stacking method of the present invention, the front-end equipment for glass cutting is an annealing furnace, which can eliminate stress and cracks inside the glass and improve the strength and stability of glass products. The annealing furnace cannot stop running. Once it stops, the glass products will cool down rapidly in a short period of time, causing cracking or bursting of the glass products. The blocker senses that the glass belt is in place, and the pressure wheel presses down to tighten it. The cutting length is intelligently calculated by the encoder and the blocker, which can well solve the problem of cutting the glass belt coming out of the front-end annealing furnace, and also ensure that the product processing meets the standards. The glass belt is continuously input into the equipment from the annealing furnace, and the equipment can continue to follow the cutting and breaking operations without stopping.

[0035] The intelligent production line for automatic cutting and stacking of glass of the present invention is particularly suitable for the production of thick optical glass. In the manufacture of spectrometers and microscopes, thick optical glass is used to make key components such as lenses and prisms. These components need to withstand greater optical and mechanical stresses, so thicker glass is required to ensure their stability and durability. The present invention can accurately control each link of glass production, ensure good processing accuracy and quality, fill the pain points of edge collapse, cracks, and low efficiency in thick glass processing, and fill the gap in the industry.
