Description
Technical Field
[0001] The present invention relates to the technical field of intelligent conveying, and more specifically, it relates to a conveying device and method for tempered glass production. Background Art
[0002] Tempered glass is glass with compressive stress on its surface, also known as strengthened glass, which is enhanced by the tempering method. It originated in France in 1874. Tempered glass is divided into physical tempered glass and chemical tempered glass according to different tempering methods, into flat tempered glass and curved tempered glass according to the shape of the tempered glass, into ordinary tempered glass, semi-tempered glass and ultra-strong tempered glass according to different tempering degrees, and into ordinary tempered glass, coated tempered glass and laminated tempered glass according to service performance, etc.
[0003] In the process of conveying tempered glass, the traditional conveying method is to place the tempered glass on a conveying rack with rubber rollers through a suction cup for transmission. For relatively long tempered glass, since there is a lot of dust in the glass production workshop, the surface of the relatively long tempered glass will be covered with dust and powder after being conveyed to the next process point. Since the subsequent process requires a clean glass surface, the conveyed tempered glass needs to be wiped additionally, which reduces the production efficiency and aesthetic degree of the tempered glass. Moreover, during the conveying process of relatively long tempered glass, foreign objects in the workshop falling onto the surface of the tempered glass will cause damage to the tempered glass. At the same time, during the conveying process of the tempered glass, due to different frictions of different rubber rollers on the surface of the tempered glass, the tempered glass will be inclined during the conveying process. If the inclination degree is too large, the corner of the tempered glass is easily stuck by the surface of the conveying rack, affecting the normal conveying of the tempered glass and having potential safety hazards.
[0004] Therefore, in order to solve the above technical problems, the present application proposes a conveying device and method for tempered glass production. Summary of the Invention

At the same time, the tempered glass will not shift during continuous conveying, ensuring the normal conveying of the tempered glass, reducing the potential safety hazards during the conveying process of the tempered glass, and solving the technical problem of inclination of the tempered glass during conveying mentioned in the background art.
[0006] To achieve the above object, the present invention provides the following technical solution: A tempered glass production conveying device, including a conveying frame, on which a number of rubber rollers are arrayed and a driving motor for driving the rubber rollers to rotate, further including: Protective covers movably arranged on both sides of the conveying frame, the protective covers are used to automatically start the protective action during the glass conveying process, a transmission device is provided on the conveying frame, and the transmission device is used to drive the protective covers to complete the rotation action through the self-weight transmission of the glass; A guiding device provided on the protective cover, the guiding device is used to automatically correct the glass moving on the conveying rollers, including a bearing block arranged on the end face of the protective cover, a moving rod is elastically arranged inside the bearing block, and a guiding disk is rotatably installed on the moving rod, and the guiding disk is used for guiding the glass.
[0007] Preferably, the transmission device includes transmission shafts symmetrically arranged on the wall of the rotating frame, a rotating block is arranged between the two transmission shafts, one ends of the two transmission shafts far away from the rotating block extend outside the conveying frame and active gears are arranged at the ends, and a torsion spring is arranged at the contact end of the transmission shaft and the conveying frame, fixing plates are fixedly installed on both sides of the conveying frame, a driven shaft is arranged on the fixing plate, and a driven gear is arranged at the end of the driven shaft.
[0008] Preferably, the driven gear meshes with the corresponding active gear, a rotating bearing is arranged on the fixing plate, and the driven shaft is rotatably installed on the fixing plate through the rotating bearing.
[0009] Preferably, the protective covers are symmetrically arranged on both sides of the conveying frame, and two symmetric protective covers are a group, and a number of groups are arranged according to the conveying length of the conveying frame, and the transmission device is correspondingly arranged with the protective cover.
[0010] Preferably, the protective cover is coupled to the driven shaft, and the rotation of the driven shaft drives the protective cover to complete the rotation action.
[0011] Preferably, the guiding devices are arranged in an array along the length direction of the protective cover, and a glass buffer space is left for the guiding devices at the end of the protective cover close to the glass.
[0012] Preferably, the guiding device includes a bearing block fixedly arranged on the inner wall of the protective cover, a telescopic groove is opened on the bearing block, a telescopic rod movable inside the bearing block is arranged in the telescopic groove, a moving rod is installed on the telescopic rod, and a guiding disk is rotatably installed on the moving rod.
[0013] Preferably, a telescopic spring is arranged on the telescopic rod, one end of the telescopic spring is fixedly connected to the moving rod at the end of the telescopic rod, and the other end is fixedly connected to the wall of the telescopic groove.
[0014] Preferably, the upper and lower end faces of the rotating block are arc-shaped, the connection end of the rotating block and the transmission shaft is located below the parallel plane of the upper end face of the rubber roller, and the protective cover is an L-shaped plate.
[0015] A method for using a conveying device for tempered glass production, comprising the following steps: S1. The glass enters the conveying rack and is conveyed by the rubber roller; S2. The front end of the glass contacts the front end face of the rotating block. Due to the self-weight of the tempered glass, when the rubber roller conveys forward, it will squeeze the front end face of the rotating block to make the rotating block rotate; S3. When the rotating block rotates, it drives the two transmission shafts connected to it to rotate synchronously, thereby driving the driving gear to rotate; S4. The driving gear drives the driven gear engaged with it to rotate, and then drives the protective cover coupled to the driven shaft to start rotating to activate the protection mode. The protective covers on both sides of the front end of the glass rotate above the glass for protection; S5. The glass continues to be conveyed forward. At this time, the guiding device rotates onto the conveying rack synchronously with the protective cover. Since there is a reserved space between the guiding device and the tempered glass, the tempered glass will continue to be conveyed forward for a certain distance before contacting the surface of the guiding disc in the guiding device; S6. When the guiding disc contacts the tempered glass, the inclined glass will squeeze the guiding disc, and the guiding disc moves in the direction of the inclination of the tempered glass under the action of the telescopic rod and the telescopic spring; S7. However, during the continuous conveying of the tempered glass, the elastic force of the telescopic spring will cause the guiding disc to reset, so the guiding disc will squeeze the tempered glass towards the middle of the conveying rack. Finally, the path of the inclined tempered glass is corrected by the guiding device during the conveying movement until it is conveyed to the next process.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a driving motor drives a rubber roller to rotate so as to convey tempered glass. During the movement of the tempered glass, the front end of the glass contacts the positive end face of the rotating block. Due to the self-weight of the tempered glass and the fact that the rotation fulcrum of the rotating block is below the conveying plane of the tempered glass, when the rubber roller conveys forward, it will squeeze the positive end face of the rotating block to make the rotating block rotate. When the rotating block rotates, it drives the two transmission shafts connected thereto to rotate synchronously, thereby driving the driving gear to rotate. The driving gear drives the driven gear engaged therewith to rotate, and further drives the protective cover coupled with the driven shaft to start rotating to activate the protection mode. One end of the L-shaped protective covers on both sides of the front end of the glass rotates above the glass for protection, covering the upper part of the tempered glass to block the dust and powder falling on the upper surface of the tempered glass, and at the same time preventing foreign objects above the tempered glass from falling and damaging the surface of the tempered glass. By utilizing the self-weight of the tempered glass and the inertia during the conveying process to drive the self-rotation of the rotating block and the protective cover, the technical problems of floating dust on the surface of the tempered glass and damage caused by foreign objects falling in the background art are solved.
[0017] 2. In the present invention, during the conveying process of the tempered glass, the rotating side of the guiding disk contacts the tempered glass. The inclined glass will squeeze the guiding disk. Since the rubber roller continuously rotates on the lower surface of the tempered glass, the inclined tempered glass will cause the guiding disk to move in the inclined direction of the tempered glass under the action of the telescopic rod and the telescopic spring. At the same time, during the continuous conveying of the tempered glass, the elastic force of the telescopic spring will drive the guiding disk to reset. Thus, the guiding disk will squeeze the tempered glass towards the middle of the conveying rack. Finally, the path of the inclined tempered glass is corrected by the guiding device during the conveying movement until it is conveyed to the next process, so that the tempered glass will not deviate during the continuous conveying process, ensuring the normal conveying of the tempered glass, reducing the safety hazards during the conveying process of the tempered glass, and solving the technical problem of the inclination of the tempered glass during conveying mentioned in the background art.

[0020] Embodiment 1
[0021] As Figures 1-7 shown, the present invention provides a conveying device for tempered glass production, including a conveyor frame 1, on which a number of rubber rollers 2 are arrayed and a driving motor 3 for driving the rotation of the rubber rollers 2, and further including: Protective covers 5 movably arranged on both sides of the conveyor frame 1, the protective covers 5 are L-shaped plates, and the protective covers 5 are used to start the protection action automatically during the glass conveying process. A transmission device 4 is provided on the conveyor frame 1, the protective covers 5 are symmetrically arranged on both sides of the conveyor frame 1, and two symmetric protective covers 5 are a group. According to the conveying length of the conveyor frame 1, several groups are set. The transmission device 4 is correspondingly arranged with the protective covers 5, and the transmission device 4 is used to drive the rotation of the protective covers 5 through the self-weight of the glass; As Figure 1 , Figure 2 and Figure 7 shown, it should be noted that for the tempered glass being conveyed, the length of the protective cover 5 is approximately the same as the length of the tempered glass conveyed on the conveyor frame 1. At the same time, the tempered glass has a certain weight and inertia during the conveying process. When the tempered glass contacts the rotating block 402, it will press the rotating block 402 downward to drive the rotation of the rotating block 402. When the end of a piece of tempered glass completely passes through the rotating block 402, the head of this piece of tempered glass will start to squeeze the next rotating block 402, so that the arrayed protective covers 5 can continue to protect the tempered glass still in the conveying process, and when the rotating block 402 rotates, it will drive the synchronous rotation of the protective covers 5 on both sides of the conveyor frame 1; The transmission device 4 includes a transmission shaft 401 symmetrically arranged on the wall of the rotating frame. A rotating block 402 is provided between the two transmission shafts 401. The upper and lower end faces of the rotating block 402 are arc-shaped. The connection end of the rotating block 402 and the transmission shaft 401 is located below the parallel plane of the upper end face of the rubber roller 2. One end of the two transmission shafts 401 away from the rotating block 402 extends outside the conveying frame 1 and a driving gear 404 is provided at each end. And a torsion spring 403 is provided at the contact end of the transmission shaft 401 and the conveying frame 1. Fixed plates 407 are fixedly installed on both sides of the conveying frame 1. A driven shaft 406 is provided on the fixed plate 407. A driven gear 405 is provided at the end of the driven shaft 406. The driven gear 405 meshes with the driving gear 404 on the corresponding side. A rotating bearing 408 is provided on the fixed plate 407. The driven shaft 406 is rotatably installed on the fixed plate 407 through the rotating bearing 408. The protective cover 5 is coupled to the driven shaft 406. The rotation of the driven shaft 406 drives the protective cover 5 to complete the rotation action.
[0022] The driving motor 3 drives the rubber roller 2 to rotate to convey the tempered glass. During the movement of the tempered glass, the front end of the glass contacts the front end face of the rotating block 402. Due to the self-weight of the tempered glass and the rotation fulcrum of the rotating block 402 being below the conveying plane of the tempered glass, when the rubber roller 2 conveys forward, it will squeeze the front end face of the rotating block 402 to make the rotating block 402 rotate. When the rotating block 402 rotates, it drives the two transmission shafts 401 connected to it to rotate synchronously, thereby driving the driving gear 404 to rotate. The driving gear 404 drives the driven gear 405 meshing with it to rotate, and then drives the protective cover 5 coupled to the driven shaft 406 to start rotating to activate the protection mode. One end of the L-shaped protective cover 5 on both sides of the front end of the glass rotates above the glass for protection, covering the upper part of the tempered glass to block the dust and powder falling on the upper surface of the tempered glass. At the same time, it can prevent foreign objects from falling above the tempered glass from damaging the surface of the tempered glass. Utilizing the self-weight of the tempered glass and the inertia during the conveying process to drive the self-rotation of the rotating block 402 and the protective cover 5 solves the technical problems of floating dust on the surface of the tempered glass and damage caused by foreign objects falling in the background art.
[0023] The guiding device 6 provided on the protective cover 5 is used to automatically correct the glass moving on the conveying roller, including a bearing block 601 provided on the end face of the protective cover 5. A moving rod 604 is elastically provided inside the bearing block 601. A guiding disc 605 is rotatably installed on the moving rod 604. The guiding disc 605 is used for guiding the glass. It should be noted that when the protective cover 5 drops, the end of the moving rod 604 is located above the conveying plane of the tempered glass. At the same time, since the guiding disc 605 is installed on the moving rod 604 through a bearing, the rotating side of the guiding disc 605 can contact the side of the tempered glass being conveyed. The guiding devices 6 are arranged in an array along the length direction of the protective cover 5, and a glass buffer space is left by the guiding device 6 at one end of the protective cover 5 close to the glass. The guiding device 6 includes a bearing block 601 fixedly arranged on the inner wall of the protective cover 5. A telescopic groove 602 is formed in the bearing block 601. A telescopic rod 603 that moves inside the bearing block 601 is arranged in the telescopic groove 602. A moving rod 604 is installed on the telescopic rod 603. A guiding disc 605 is rotatably installed on the moving rod 604. A telescopic spring 606 is arranged on the telescopic rod 603. One end of the telescopic spring 606 is fixedly connected to the moving rod 604 at the end of the telescopic rod 603, and the other end is fixedly connected to the wall of the telescopic groove 602. During the transportation of the tempered glass, the rotating side of the guiding disc 605 contacts the tempered glass. The inclined glass will squeeze the guiding disc 605. Since the rubber roller 2 continuously rotates on the lower surface of the tempered glass, the inclined tempered glass will cause the guiding disc 605 to move in the direction of the inclination of the tempered glass under the action of the telescopic rod 603 and the telescopic spring 606. At the same time, during the continuous transportation of the tempered glass, the elastic force of the telescopic spring 606 will drive the guiding disc 605 to reset. As a result, the guiding disc 605 will squeeze the tempered glass towards the middle of the conveying rack 1. Eventually, the path of the inclined tempered glass is corrected by the guiding device 6 during the transportation process until it is conveyed to the next process, ensuring that the tempered glass does not shift during continuous transportation, ensuring the normal transportation of the tempered glass, reducing the safety hazards during the transportation of the tempered glass, and solving the technical problem of the inclination of the tempered glass during transportation mentioned in the background technology.
[0024] The driving motor 3 drives the rubber roller 2 to rotate to convey the tempered glass. During the movement of the tempered glass, the front end of the glass contacts the front end face of the rotating block 402. Due to the self-weight of the tempered glass and the fact that the rotation fulcrum of the rotating block 402 is below the conveying plane of the tempered glass, when the rubber roller 2 conveys forward, it will squeeze the front end face of the rotating block 402 to make the rotating block 402 rotate. When the rotating block 402 rotates, it drives the two transmission shafts 401 connected to it to rotate synchronously, thereby driving the driving gear 404 to rotate. The driving gear 404 drives the driven gear 405 meshing with it to rotate, and then drives the protective cover 5 coupled to the driven shaft 406 to start rotating to activate the protection mode. The L-shaped ends of the protective covers 5 on both sides of the front end of the glass rotate above the glass for protection, covering the upper part of the tempered glass. At this time, the rotating side of the guiding disc 605 contacts the tempered glass, and the inclined glass will squeeze the guiding disc 605. Since the rubber roller 2 continuously rotates on the lower surface of the tempered glass, the inclined tempered glass will cause the guiding disc 605 to move in the inclined direction of the tempered glass under the action of the telescopic rod 603 and the telescopic spring 606. At the same time, during the continuous conveying of the tempered glass, the elastic force of the telescopic spring 606 will drive the guiding disc 605 to reset. As a result, the guiding disc 605 will squeeze the tempered glass towards the middle of the conveying rack 1. Finally, the path of the inclined tempered glass is corrected by the guiding device 6 during the conveying and moving process until it is conveyed to the next process.
[0025] Embodiment 2
[0026] As Figures 1-7 shown, the present invention provides a method for using a conveying device for producing tempered glass, including the following steps: S1. The glass enters the conveying rack 1 and is conveyed through the rubber roller 2; S2. The front end of the glass contacts the front end face of the rotating block 402. Due to the self-weight of the tempered glass, when the rubber roller 2 conveys forward, it will squeeze the front end face of the rotating block 402 to make the rotating block 402 rotate; S3. When the rotating block 402 rotates, it drives the two transmission shafts 401 connected thereto to rotate synchronously, thereby driving the driving gear 404 to rotate; S4. The driving gear 404 drives the driven gear 405 meshing therewith to rotate, and further drives the protective cover 5 coupled to the driven shaft 406 to start rotating to activate the protection mode. The protective covers 5 on both sides of the front end of the glass rotate above the glass for protection; S5. The glass continues to be conveyed forward. At this time, the guiding device 6 rotates synchronously with the protective cover 5 onto the conveying rack 1. Since there is a reserved space between the guiding device 6 and the tempered glass, the tempered glass will contact the surface of the guiding disc 605 in the guiding device 6 after continuing to be conveyed forward for a certain distance; S6. When the guiding disc 605 contacts the tempered glass, the inclined glass will squeeze the guiding disc 605, and the guiding disc 605 moves in the inclined direction of the tempered glass under the action of the telescopic rod 603 and the telescopic spring 606; S7. However, during the continuous conveying of the tempered glass, the elastic force of the telescopic spring 606 will drive the guiding disc 605 to reset. As a result, the guiding disc 605 will squeeze the tempered glass towards the middle of the conveying rack 1. Finally, the path of the inclined tempered glass is corrected by the guiding device 6 during the conveying and moving process until it is conveyed to the next process.
