Description

Technical Field

[0001] The present application relates to the technical field of glass plate production, and in particular to a glass conveying device. Background Art

[0002] In the field of glass production such as cover glass, for example, in the field of high-end cover glass produced by float technology, after the glass is taken out of the annealing furnace, it will enter the cold end process of the production line, which includes eight areas: emergency drop plate area, defect inspection area, cutting horizontal breaking area and edge cleaning vertical breaking area. The glass temperature of the cold end process is still residual, the quality is soft and it is easy to produce waste chips. The main glass defects in its processing are scratches and soft abrasions caused by the transportation process.

[0003] Scratch defects are the main inspection defects of mid- and low-end glass. They can be detected under point light sources. They are caused by glass fragments mixed on the rubber rollers or the metal structure of the rollers during the movement of the glass. The usual process countermeasures are to check and clean the rollers according to the scratch location, and the problem can be solved. Soft scratch defects are the main inspection defects of high-end glass. They are more hidden and difficult to find. They are usually only about 1mm in length. They are caused by dust adhering to the rollers and the speed difference between adjacent rollers. They can only be inspected by irradiating with a strong flashlight. The inspection cost and repair cost are higher, which seriously affects the product yield of high-end glass cover plates.

[0004] In the existing glass transportation devices, due to cost considerations, usually only one conveying production line is used to transport glass strips of different specifications, and the conveying method is mostly a single conveying structure of conveyor rollers.

The glass is conveyed by conveyor rollers, and a blowing mechanism is set at both ends of the conveyor rollers for blowing to reduce the probability of glass scratches. However, the actual effect of this solution is very limited in the glass processing plant filled with waste debris.

[0035] Figures 1 to 6 An embodiment of the glass conveying equipment of the present application is schematically shown.

[0036] like Figures 1 to 6 As shown, the present application discloses a glass conveying device, including: a first glass conveying mechanism 1, including a plurality of conveying rollers 11 arranged at intervals, and a driving mechanism for driving the conveying rollers 11 to rotate. A second glass conveying mechanism 2, including a plurality of liftable top wheels 21 and a plurality of liftable pressure wheels 22, the material hardness of the top wheels 21 being higher than that of the conveying rollers 11. The top wheels 21 are arranged in the gap between the conveying rollers 11 and are located below the middle effective area of ​​the glass, and can lift the middle effective area of ​​the glass to separate from the conveying rollers 11, and rotate with the movement of the glass. The pressure wheels 22 are arranged above the edge invalid area of ​​the glass, and can press down the edge invalid area of ​​the glass to make it close to the conveying rollers 11. Among them, the middle effective area of ​​the glass refers to the middle area of ​​the glass ribbon, which may be retained to support the cost part such as the glass cover plate later; the edge invalid area of ​​the glass refers to the part of the glass that will be cut or discarded later.

[0037] Through the above structural design, the present application has two sets of glass conveying mechanisms at the same time: the first glass conveying mechanism 1 uses a low-hardness conveying roller 11 to actively convey ordinary glass; the second glass conveying mechanism 2 uses a high-hardness top wheel 21 to passively convey high-end glass. The high-hardness top wheel 21 can reduce the adhesion of environmental dust and glass waste, and transports the glass in a passive rotation manner without speed difference as the glass rotates, thereby avoiding the problem of soft scratches caused by dust and speed difference. At the same time, the present application is arranged with a pressure wheel 22 together with the top wheel 21. The pressure wheel 22 can press the invalid area of ​​the glass edge to overcome the loss of traction after the middle of the glass is lifted up, and ensure the reliability of glass transmission.

[0038] In some embodiments of the present application, the conveying roller 11 is made of nitrile rubber, EPDM or fluororubber, with a hardness of 50-70A. The top wheel 21 is made of PU material, with a hardness of more than 90A. The above material combination is adopted because the applicant has found in actual production that the cold end conveying rollers of the float production line that are currently used internationally to save costs are all made of soft rubber materials. Under this roller production method, soft scratches are almost all over the glass. Through experiments, it is found that the main cause is: in the two areas of the emergency drop plate area and the defect inspection area, since the glass has just been taken out of the furnace, the temperature is still relatively high (about 80℃~70℃), and the roller of soft rubber material will adhere to a large amount of tiny environmental dust and glass waste, thus causing imperceptible soft scratches on the tin surface of the glass. For most ordinary users, the soft scratches of this soft rubber roller are not obvious, and the surface quality of the produced glass can meet the requirements. Therefore, the industry tends to use soft rubber rollers for production, while for some users with higher requirements for glass quality, such soft scratches are not allowed for high-end glass. Therefore, the present application adopts a design scheme of a double transmission mechanism. On the one hand, the traditional soft rubber roller is retained unchanged, and the transmission roller is made of soft rubber materials such as nitrile rubber, EPDM or fluororubber. The hardness of the transmission roller 11 is controlled to be 50-70A, preferably 60A, to ensure that most ordinary glass production is completed efficiently while controlling costs; on the other hand, the present application adds a top wheel 21 structure, and positions its material as PU material, and sets the hardness to be above 90A, thereby reducing the probability of the top wheel 21 adhering to environmental dust and glass waste by increasing the hardness. After the top wheel 21 is used to lift the glass off the transmission roller 11, the probability of soft scratches on the glass is greatly reduced. At the same time, since the top wheel 21 is a liftable structure, it can be flexibly lifted and lowered between the production of ordinary glass and the production of high-end glass to switch the working mode, the service life can be extended, and the production cost can be controlled. In addition, during actual use, the glass plate 3, such as ultra-thin glass, has a certain degree of bendability, and the top wheel 21 can lift it up and away from the conveying roller by about 2 mm, so that the edge invalid area of ​​the glass plate 3 can still stay on the conveying roller 11 and be driven by the rotation of the conveying roller 11. Moreover, the pressing wheel 22 of the present application will also descend as the top wheel 21 rises, further pressing the edge invalid area of ​​the glass plate 3, minimizing the loss of traction of the glass plate 3 as much as possible, so as to ensure the smooth transmission of the glass plate 3.

[0039] In some embodiments of the present application, Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the second glass conveying mechanism 2 also includes a top wheel beam 211. The top wheel beam 211 is arranged parallel to the conveying roller 11, and its two ends are respectively connected to synchronous lifting cylinders 212. A plurality of top wheel frames 213 are evenly distributed on the top wheel beam 211, and each top wheel frame 213 is provided with a top wheel 21. Therefore, the present application arranges the top wheels 21 in groups through the top wheel beam 211, and each group of top wheels 21 can be raised and lowered synchronously to improve the stability of the contact and transportation glass plate 3. In the embodiment of the present application, 8 top wheels 21 are evenly distributed on each top wheel beam 211. Of course, the specific number of top wheels can be flexibly set according to actual conditions. In some preferred embodiments of the present application, the top wheel beam 211 is made of aluminum alloy, which is light in weight and high in strength, and a reinforcing connecting plate can be added below it to further improve the strength and reliability.

[0040] In some embodiments of the present application, reference Figure 5 and Figure 6 As shown, one end of the top wheel beam 211 is connected to the synchronous lifting cylinder 212 by a round hole 2142 and a pin, and the other end of the top wheel beam 211 is connected to the synchronous lifting cylinder 212 by a waist-shaped hole 2143 and a pin. This connection method of a round hole at one end and a waist-shaped hole at the other end can, on the one hand, limit the position of the top wheel beam 211 through the round hole 2142 so that it will not have a large front-to-back displacement change, and on the other hand, it can provide a small amount of front-to-back movement space through the waist-shaped hole 2143 to avoid jamming when there is a difference in the movement of the synchronous lifting cylinder 212, thereby ensuring the position stability and lifting reliability of the top wheel beam 211. In the embodiment of the present application, the cylinder head of the synchronous lifting cylinder 212 is connected to the shaft pin through a Y-shaped joint, and then connected to the top wheel beam 211. The round hole 2142 and the waist-shaped hole 2143 are both arranged on the connecting hanger and connected to the top wheel beam 211.

[0041] In some embodiments of the present application, reference Figure 1 , Figure 4 and Figure 5 As shown, the conveying roller 11 is provided with a roller support 12, and the roller support 12 is provided with a driving gear 13 and a passive gear 14. The driving gear 13 is driven by a variable frequency motor and is made of high-quality carbon steel. The passive gear 14 is made of nylon. The meshing of the gears of the two materials can reduce vibration, reduce noise, and improve the operation quality of the equipment. A gap of 110 mm is designed between adjacent conveying rollers 11 to ensure a safe distance, and reserve space for installing the top wheel 21.

[0042] In some embodiments of the present application, reference Figure 1 , Figure 4 and Figure 5As shown, the second glass conveying mechanism 2 further includes a top wheel suspension seat 214, which is arranged on the roller support 12, so as to reasonably utilize the structural space and make the device compact. A synchronous lifting cylinder 212 is installed on the top wheel suspension seat 214, and a U-shaped limiting groove 2141 is arranged below the top wheel suspension seat 214. The top wheel cross beam 211 is connected to the synchronous lifting cylinder 212 and is inserted into the U-shaped limiting groove 2141, and moves up and down along the U-shaped limiting groove 2141. The U-shaped limiting groove 2141 can prevent the top wheel cross beam 211 from tilting and swinging under force during operation, thereby improving the working stability of the top wheel cross beam 211 and the top wheel 21 thereon.

[0043] In some embodiments of the present application, a cleaning mechanism is provided on the top wheel frame 213 of the present application corresponding to the top wheel 21. The cleaning mechanism is in contact with the top wheel 21 and automatically cleans the surface of the top wheel 21 as the top wheel 21 rotates, thereby further reducing the possibility of the top wheel 21 adhering to environmental dust and glass waste.

[0044] refer to Figure 3 and Figure 4 As shown, in the illustrated embodiment of the present application, the cleaning mechanism includes a cleaning felt 215 and a felt seat 216. The felt seat 216 is fixedly arranged below the top wheel 21, and a groove is arranged on the top thereof to place the cleaning felt 215. There are two cleaning felts 215, which are arranged on both sides of the bottom of the top wheel 21 and contact the top wheel 21. Moreover, there is a dust discharge gap between the two cleaning felts 215. For example, the dust discharge gap is set to 5 mm to facilitate the discharge of dust.

[0045] In some embodiments of the present application, Figure 3 As shown, an adjustment seat 217 is provided below the top wheel frame 213, and an adjustment wire 218 is provided on the adjustment seat 217. The adjustment wire 218 can be rotated to adjust the installation height of the top wheel frame 213, so that the initial working height of the top wheel 21 can be adjusted according to actual conditions to meet the transmission requirements of different glass plates 3.

[0046] In some embodiments of the present application, Figure 1 As shown, the second glass conveying mechanism 2 further includes a pressure wheel fixing frame 221, which can be directly erected on the ground on both sides of the conveying roller 11 to press the glass plate from the upper side downward. A guide rod cylinder 222 is provided on the pressure wheel fixing frame 221, and a pressure wheel seat 223 is provided at the lower movable end of the guide rod cylinder 222, and the pressure wheel 22 is installed in the pressure wheel seat 223. The guide rod cylinder 222 moves synchronously with the synchronous lifting cylinder 212 or moves before the synchronous lifting cylinder 212, so that when the lifting wheel 21 lifts the middle effective area of ​​the glass plate 3, the edge invalid area of ​​the glass plate 3 is pressed against the conveying roller 11, thereby reducing the traction damage of the glass plate 3.

[0047] In some embodiments of the present application, the glass conveying device also includes a controller, and a broken plate detection mechanism that may also need to be installed. The controller is electrically connected to the second glass conveying mechanism 2, and can switch the operation mode of the second glass conveying mechanism 2 at any time, that is: when producing ordinary glass, the top wheel 21 is controlled to descend and the pressure wheel 22 is controlled to ascend, so that the glass conveying device of the present application works in the ordinary mode, and ordinary glass is produced in a low-cost manner; when producing high-end glass with higher requirements, the top wheel 21 is controlled to ascend and the pressure wheel 22 is controlled to descend, so that the glass conveying device of the present application works in the high-end mode, and the glass plate 3 is lifted up to avoid soft scratch defects and improve the production yield of high-end glass plates 3. The broken plate detection mechanism is electrically connected to the controller, and can detect the broken fault of the glass plate 3 of the production line, and send the broken plate detection information to the controller before the broken glass plate 3 enters the device, so that the controller can timely control the top wheel 21 to descend and the pressure wheel 22 to ascend, so as to achieve timely avoidance.

[0048] Combination Figures 1 to 6 As shown, it explains the working principle of this application:

[0049] When producing high-end glass with higher requirements, the top wheel 21 rises and the pressure wheel 22 falls. The top wheel 21 makes the middle effective area of ​​the glass plate 3 separate from the conveying roller 11, thereby avoiding the problem that the conveying roller 11 is soft and easy to adhere to environmental dust and glass waste, which easily causes soft scratches on the glass plate 3. At the same time, since the glass plate 3 is still in a hot state and has a relatively soft texture at this time, the invalid areas on both sides of the edge of the glass plate 3 that are not lifted up still droop and contact the conveying roller 11, receiving the conveying friction of the conveying roller 11, and the descending pressure of the pressure wheel 22 of the present application can also press the invalid area of ​​the edge of the glass plate 3 on the conveying roller 11, thereby compensating for the traction loss of the middle of the glass plate 3 being lifted up, so that the glass plate 3 can still continue to be smoothly conveyed under the rotation of the conveying roller 11. On this basis, since the top wheel 21 rotates in a non-powered manner following the movement of the glass plate 3, the top wheel 21 and the glass plate 3 maintain synchronous motion without speed difference, which further avoids the problem of soft scratches caused by relative friction. In the embodiment of the present application, 8 top wheels 21 are installed on each top wheel crossbeam 211 in the middle effective area of ​​the glass plate 3, and the spacing is uniform. When producing high-end cover glass with relatively high requirements for soft scratches, the synchronous lifting cylinder 212 is lifted, driving the corresponding top wheel crossbeam 211 to rise, so that the top wheel 21 rises, supporting the effective area of ​​the glass plate 3 from the conveying roller 11, avoiding the glass plate 3 and the conveying roller 11 from contacting and rubbing to produce soft scratches, and the top wheel 21 is in contact with the tin surface (i.e., the bottom surface) of the glass plate 3, rotating with the movement of the glass plate 3, and thus having zero speed difference with the glass plate 3, which can further avoid the problem of relative sliding friction scratching the glass plate 3. When continuous production encounters a cracked plate in the annealing kiln, under the automatic detection of the broken plate detection mechanism, or under the active discovery of manual monitoring, before the broken glass reaches the top wheel 21, the top wheel 21 is controlled by the controller to immediately descend and switch to the conveying mode of the conveying roller 11, which can avoid the broken glass from hitting the top wheel 21 and protect the safety of the equipment. When producing glass products that do not require soft scratches, the top wheel 21 descends and the pressure wheel 22 rises, switching the glass conveying equipment of the present application to a common roller conveying mode to reduce production costs and extend the service life of the top wheel 21.

[0050] In summary, the glass conveying equipment of the present application includes: a first glass conveying mechanism and a second glass conveying mechanism, the first glass conveying mechanism includes a plurality of conveying rollers arranged at intervals and a driving mechanism for driving the conveying rollers to rotate; the second glass conveying mechanism includes a plurality of liftable top wheels and a plurality of liftable pressure wheels, the material hardness of the top wheels is higher than that of the conveying rollers; the top wheels are arranged in the gaps between the conveying rollers and are located below the middle effective area of ​​the glass, and can lift the middle effective area of ​​the glass to separate from the conveying rollers and rotate with the movement of the glass; the pressure wheels are arranged above the edge invalid area of ​​the glass, and can press down the edge invalid area of ​​the glass to make it close to the conveying rollers. The present application also has two sets of glass conveying mechanisms. The first glass conveying mechanism uses a low-hardness conveying roller to actively convey ordinary glass, and the second glass conveying mechanism uses a high-hardness top wheel to passively convey high-end glass. The high-hardness top wheel can reduce the adhesion of environmental dust, and uses a passive rotation method to transport the glass without speed difference, thereby avoiding soft scratches caused by dust and speed difference. At the same time, the present application is arranged with a pressure wheel together with the top wheel. The pressure wheel can press the invalid area of ​​the glass edge, overcome the loss of drag force after the glass is lifted, and ensure the reliability of glass transmission.
