A float glass production online red plate glass adjustable transmission method and adjustment device

Abstract

The present invention discloses an adjustable transmission method for red plate glass in float glass production line. The glass is broken by a breaking roller and then transported to a transport roller. During the process, it is detected whether the glass is red plate glass. If it is red plate glass, the timing starts when the red plate glass passes through the first photoelectric switch sensor 2. If the red plate glass leaves the photoelectric switch sensor 2 within a certain period of time, it is determined that the red plate glass cannot cross and contact multiple transport rollers at the same time. At this time, the cylinder works to lift the red plate glass, and the rotating motor works to drive the cylinder to rotate through the rotating base, thereby driving the red plate glass to rotate. When two photoelectric switch sensors detect the red plate glass at the same time, the rotation stops, and the cylinder resets to make the red plate glass fall on the transport roller again for transportation. The present invention can automatically detect the red plate glass and automatically adjust the placement angle of the red plate glass, effectively improving the yield rate, output and production efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of glass processing, in particular to an adjustable transmission method and an adjusting device of an online red plate glass for float glass production. Background Art

[0002] The calcination of float glass is done in a very high-temperature large furnace, which does not stop all year round, and the output line does not stop. In the float glass production line, the glass needs to be cut and broken at the output end, thereby producing positive plate glass that meets the specifications of the finished product, and defective products and scraps that do not meet the specifications. These defective products and scraps are collectively referred to as red plate glass, which generally need to be broken by a crusher for recycling. Due to the high operating cost of the float glass calcining furnace, the spacing between the conveyor rollers cannot be modified, and generally there is no interruption after the start of work. The produced glass is continuously conveyed by the conveyor rollers. Even if glass falls in the middle, it will not be paused, but conveyed continuously. The accumulation of dropped glass during this period may cause collisions and scratches on the subsequently conveyed glass, resulting in a decrease in the yield rate, and even damage to the conveyor line, affecting the production of the entire kiln.

[0003] In the glass production line, the output end of the kiln is shaped at high temperature and does not stop for many years. The minimum length of the red plate glass after cutting at the existing output end is 500mm. Through other auxiliary adjustments and improvements, it can only be reduced to 380mm. The maximum cutting distance of the production line cutting system is 300mm. However, since the spacing between the rollers of the conveying rollers is generally 250mm, the angle of the cut red plate glass may deviate when it is transferred to the conveying rollers, causing the red plate glass to be placed obliquely and unable to contact and convey with multiple rollers at the same time. As a result, the red plate glass below 380mm may fall from the gap between adjacent rollers and fall off the production line, blocking the production line and crashing the equipment, while the size of the positive plate glass after cutting is still large enough to be conveyed across multiple rollers and will not fall. Therefore, it is necessary to provide an adjustable transmission method and adjustment device for red plate glass in the float glass production line, which can automatically detect whether it is a certain size of red plate glass, and automatically adjust the red plate glass that is not large enough to contact and convey across multiple conveying rollers. Summary of the invention

[0004] The present invention provides an adjustable transmission method and an adjusting device for red plate glass in float glass production line to solve the problems raised in the above background technology.

[0005] To solve the above problems, the technical solution adopted by the present invention is:

[0006] A float glass production online red plate glass adjustable transmission method, comprising the following steps:

[0007] S1. After the glass is fired in the float glass calcining furnace, it is cut and processed. After cutting, the glass is broken by a breaking roller and then conveyed to a conveying roller. During this period, a photoelectric switch sensor 1 is provided under the breaking roller. The photoelectric switch sensor detects the passing time of the glass to determine whether the glass is red plate glass;

[0008] S2, two photoelectric switch sensors 2 are arranged above the conveying rollers. If it is red plate glass, the timing starts when the red plate glass passes the first photoelectric switch sensor 2. If the red plate glass can still sense the two photoelectric switch sensors 2 arranged at this interval at a certain time, it is determined that the placement angle of the red plate glass can cross and contact multiple conveying rollers at the same time, and it is determined to be a positive red plate glass. Otherwise, the red plate glass cannot cross and contact multiple conveying rollers at the same time, and it is determined to be a small piece of red plate glass, so it may fall;

[0009] S3. A lifting and rotating device consisting of a cylinder and a rotating base is arranged below the conveying roller between the two photoelectric switch sensors 2. When a small piece of red plate glass is determined, the cylinder works to lift the red plate glass, and the rotating motor works to drive the cylinder to rotate through the rotating base, thereby driving the red plate glass to rotate;

[0010] S4, when the two photoelectric switch sensors detect the red plate glass at the same time during the rotation in step S, the rotation is stopped immediately, the cylinder is reset so that the red plate glass falls back on the conveying roller for conveying, the rotating motor is reset, and the above steps are repeated to realize the automatic detection and automatic angle adjustment of the online small piece of red plate glass for processing;

[0011] The above steps are completed by using an adjustment device with conveying, detecting and adjusting structures.

[0012] Preferably, an adjustment device for the adjustable transmission method of red plate glass in the float glass production line as mentioned above, the adjustment device includes a frame and a breaking roller and a conveying roller installed on the frame, a photoelectric switch sensor 1 is installed on the frame below the breaking roller, and two photoelectric switch sensors 2 are installed on the frame above one end of the conveying roller near the breaking roller, and the spacing between the two photoelectric switch sensors 2 is 00mm, and a lifting and rotating device for adjusting the placement angle of the red plate glass is provided below the conveying roller, the lifting and rotating device, the photoelectric switch sensor 1, and each of the photoelectric switch sensors 2 are respectively connected to a controller to form a detection structure for automatically detecting the glass on the breaking roller and an adjustment structure for automatically adjusting the glass placement angle.

[0013] Preferably, the lifting and rotating device includes a cylinder, the movable end of the cylinder faces upward and is telescopically movable in the gap between two adjacent rollers, the lateral position of the cylinder is located between the two photoelectric switch sensors, and the cylinder is connected to a battery valve.

[0014] Preferably, an anti-skid pad is provided on the top of the movable end of the cylinder to increase the friction between the movable end of the cylinder and the glass to prevent the glass from falling during rotation.

[0015] Preferably, a rotating base is installed at the bottom of the cylinder, the bottom of the rotating base is connected to the output shaft of a rotating motor, and the rotating motor and the battery valve are respectively connected to the controller.

[0016] Preferably, a support roller is installed on the frame between the breaking roller and the adjacent roller wheel to help the glass to transition from the breaking roller to the conveying roller wheel.

[0017] Preferably, the conveying roller includes a plurality of roller shafts, each of the roller shafts is provided with a gear 1 at the same end, each of the gear 1s is meshedly connected through the same chain, a driving motor is installed on the frame, and the output shaft of the driving motor is provided with a gear 2, and the gear 2 is meshedly connected with one end of the chain.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention installs a pair of photoelectric switch sensors on a frame to detect whether the glass is red plate glass, and two photoelectric switch sensors detect whether the placement angle of the red plate glass is correct. After the red plate glass passes through the photoelectric switch sensor one, the two photoelectric switch sensors detect the red plate glass at the same time, which means that the glass can be transported across multiple conveying rollers and will not fall. If the two photoelectric switch sensors cannot detect the red plate glass at the same time, the glass cannot be transported across multiple conveying rollers and may fall between the two conveying rollers. At this time, the lifting and rotating device is used to adjust the placement angle of the red plate glass, so as to realize the effect of automatically detecting the red plate glass and automatically adjusting the placement angle of the red plate glass, thereby preventing the 300mm-380mm red plate glass from falling from the gap between adjacent rollers, and completely realizing the transportation of small plates less than 380mm, effectively improving the yield rate, and improving the output and production efficiency.

[0020] Photoelectric switch sensor 1 and photoelectric switch sensor 2 are used together for detection to automatically identify whether the glass on the production line is red plate glass. The lifting and rotating device is used to detect and adjust the red plate glass in real time during the glass cutting and conveying process, realizing the integrated detection and processing of conveying, detection and adjustment, greatly reducing the possibility of red plate glass falling and preventing production line blockage.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 3 Embodiment 1: A float glass production online red plate glass adjustable transmission method, comprising the following steps:

[0027] S1. After the glass is fired in the float glass calcining furnace, it is cut and processed. After cutting, the glass is broken by the breaking roller 3 and then conveyed to the conveying roller 4. During this period, a photoelectric switch sensor 21 is provided under the breaking roller 3. The photoelectric switch sensor 21 detects the passing time of the glass to determine whether the glass is red plate glass;

[0028] S2, two spaced photoelectric switch sensors 22 are arranged above the conveying roller 4. If it is red plate glass, the timing starts when the red plate glass passes the first photoelectric switch sensor 22. If the red plate glass can still sense the two photoelectric switch sensors 22 at the interval at a certain time, it is determined that the placement angle of the red plate glass can cross and contact multiple conveying rollers 4 at the same time, and it is determined to be a positive red plate glass. Otherwise, the red plate glass cannot cross and contact multiple conveying rollers 4 at the same time, and it is determined to be a small piece of red plate glass, so it may fall off;

[0029] S3. A lifting and rotating device 5 consisting of a cylinder 51 and a rotating base 53 is arranged below the conveying roller 4 between the two photoelectric switch sensors 22. When a small piece of red plate glass is determined, the cylinder 51 works to lift the red plate glass, and the rotating motor 54 works to drive the cylinder 51 to rotate through the rotating base 53, thereby driving the red plate glass to rotate;

[0030] S4, when the two photoelectric switch sensors simultaneously detect the red plate glass during the rotation in step S3, the rotation is stopped immediately, the cylinder 51 is reset so that the red plate glass falls back on the conveying roller 4 for conveying, the rotary motor 54 is reset, and the above steps are repeated to realize the automatic detection and automatic angle adjustment of the online small piece of red plate glass for processing;

[0031] The above steps are completed by using an adjustment device with conveying, detecting and adjusting structures.

[0032] An adjustment device for the adjustable transmission method of red plate glass in the float glass production line as mentioned above, the adjustment device comprises a frame 1 and a breaking roller 3 and a conveying roller 4 installed on the frame 1, a photoelectric switch sensor 1 21 is installed on the frame 1 below the breaking roller 3, two photoelectric switch sensors 22 are installed on the frame 1 above one end of the conveying roller 4 close to the breaking roller 3, and the spacing between the two photoelectric switch sensors 22 is 300mm, and a lifting and rotating device 5 for adjusting the placement angle of the red plate glass is provided below the conveying roller 4, the lifting and rotating device 5, the photoelectric switch sensor 1 21, and each of the photoelectric switch sensors 22 are respectively connected to a controller to form a detection structure for automatically detecting the glass on the breaking roller 3 and an adjustment structure for automatically adjusting the glass placement angle.

[0033] The lifting and rotating device 5 includes a cylinder 51 , the movable end of which faces upward and is telescopically movable in the gap between two adjacent rollers 4 . The lateral position of the cylinder 51 is located between the two photoelectric switch sensors. The cylinder 51 is connected to a battery valve 52 .

[0034] The top of the movable end of the cylinder 51 is provided with an anti-skid pad to increase the friction between the movable end of the cylinder 51 and the glass to prevent the glass from falling during rotation.

[0035] A rotating base 53 is installed at the bottom of the cylinder 51 . The bottom of the rotating base 53 is connected to the output shaft of a rotating motor 54 . The rotating motor 54 and the battery valve 52 are respectively connected to a controller.

[0036] A support roller 6 is installed on the frame 1 between the breaking roller 3 and the adjacent roller wheel 4 to help the glass transition from the breaking roller 3 to the conveying roller wheel 4.

[0037] The conveying roller 4 includes a plurality of roller shafts 42, each of which is provided with a gear 1 43 at the same end, and each of the gear 1 43 is meshedly connected through the same chain 45. A driving motor 41 is installed on the frame 1, and a gear 2 44 is installed on the output shaft of the driving motor 41, and the gear 2 44 is meshedly connected with one end of the chain 45.

[0038] When the present invention is used, the glass is transported to the conveying roller 4 with the assistance of the supporting roller 6 after being broken by the breaking roller 3. During this period, the photoelectric switch sensor detects the glass and transmits the detection data to the controller to detect whether it is red plate glass. If it is, the photoelectric switch sensor 22 close to the breaking roller 3 works to detect the time when the red plate glass passes through the photoelectric switch sensor 22. If it leaves the sensing range of the photoelectric switch sensor within the specified time, it is a red plate glass with a position deviation. The controller controls the battery valve 52 to work with the cylinder 51 to lift the red plate glass, and then the rotating motor 54 works to drive the red plate glass to rotate until both photoelectric switch sensors can detect the red plate glass, that is, the angle adjustment is completed. Then the cylinder 51 is reset to make the red plate glass fall back on the conveying roller 4 for transportation, and the rotating motor 54 is reset. Repeat the above steps to realize automatic detection and automatic angle adjustment of the red plate glass for processing.

[0039] Embodiment 2, based on embodiment 1, the rotation angle of the rotating motor 54 of the present invention does not exceed 40°. When adjusting the red plate glass, it is first rotated 10° to 30° in a clockwise direction. If the two photoelectric switch sensors 22 cannot detect the red plate glass at the same time, the rotating motor 54 is reset and then rotated 10° to 30° in a counterclockwise direction to adjust the red plate glass to a state where the two photoelectric switch sensors 22 can detect it at the same time, so as to meet the requirement of contacting and conveying across multiple conveying rollers 4 at the same time. During this period, since the glass in production needs to be cut and the conveying rollers 4 in the float glass production line are generally slow, the lifting and rotating device 5 has enough time to adjust the red plate glass.

[0040] The present invention can automatically detect the red plate glass and automatically adjust the placement angle of the red plate glass, effectively improving the yield, output and production efficiency.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
