Description

Technical Field

[0001] The invention relates to the technical field of automatic feeding, in particular to an automatic feeding device for a glass tempering furnace. Background Art

[0002] A tempering furnace is a device that produces tempered glass by physical or chemical methods. When the glass is tempered, ordinary glass needs to be placed on a conveying mechanism, and the conveying mechanism is used to move the ordinary glass into the tempering furnace for tempering. A Chinese patent with announcement number "CN1173208A" provides an automatic loading system for a glass tempering furnace. The application sets supports on both sides of a main frame, and sets adsorption components and flip components on the supports. The flip component will drive the adsorption component to adsorb the glass, thereby transporting the glass to the roller conveyor component of the main frame for transportation, so that the glass can be transported regularly and efficiently, reducing labor input costs and labor safety hazards. However, each time the glass is transported to the conveying component, the distance between the next piece of glass and the flip component will increase, and the adsorption component will find it difficult to adsorb the subsequent glass. In addition, when processing small glass, the distance between the glass and the adsorption component is large, the contact between the adsorption component and the glass is small, and the adsorption strength is low. Summary of the invention

[0003] The object of the present invention is to provide an automatic glass loading device for a glass tempering furnace to solve the problems raised in the above background technology.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] See also Figures 1 to 7 The present invention provides an automatic glass tempering furnace loading device, comprising a support frame 1, on which an array of conveying rollers 2 are rotatably connected, one side of the support frame 1 is rotatably connected to a rotating rod 3, a support rod 4 is fixedly connected to the rotating rod 3 at a position between two adjacent conveying rollers 2, each of the support rods 4 is fixedly connected to an adsorption mechanism 5, one side of the support frame 1 is fixedly connected to a transmission motor 6 for driving the rotating rod 3 to rotate, a moving mechanism 7 is fixedly connected to the lower side of the support frame 1, and the support frame 1 is equipped with a follower mechanism 8 for driving the glass to move toward the support frame 1.

[0031] The movable mechanism 7 is provided to drive the storage rack with the glass to move, the transmission motor 6 drives the rotating rod 3 to rotate, the rotating rod 3 rotates to drive the supporting rod 4 to rotate, the supporting rod 4 rotates to drive the adsorption mechanism 5 to move to the glass, adsorb the glass, increase the contact area between the adsorption mechanism 5 and the glass, and improve the adsorption strength. When the rotating rod 3 is turned over, the follower mechanism 8 is driven to move, and the storage rack is driven to move toward the supporting frame 1, so that each glass on the storage rack can keep the same distance with the supporting frame 1 after the rotating rod 3 drives the previous glass to be loaded, so that the rotating rod 3 drives the adsorption mechanism 5 to accurately adsorb glasses of different specifications, and avoids a large difference in the distance between the glass and the adsorption mechanism 5, which makes it difficult for the adsorption mechanism 5 to adsorb and load the glass.

[0032] See also Figure 6 and Figure 7 The adsorption mechanism 5 includes a suction cup 9 fixedly connected to the support rod 4, a fixed tube 10 is arranged on the outer shell of the suction cup 9, a first mounting groove 11 is provided on the fixed tube 10, an annular sleeve 12 is slidably connected in the first mounting groove 11, an air outlet 13 is provided at one end of the annular sleeve 12 away from the fixed tube 10, a separator ring 14 is fixedly connected to one end of the suction cup 9 away from the support rod 4, the separator ring 14 is slidably connected to the inner wall of the annular sleeve 12, and a first spring 43 is fixedly connected between the annular sleeve 12 and the first mounting groove 11.

[0033] In the initial state, under the action of the first spring, the same side of the fixed cylinder 10 and the annular sleeve 12 are away from each other. When the support rod 4 rotates, the suction cup 9 and the fixed cylinder 10 will be driven to rotate. When the fixed cylinder 10 rotates, the annular sleeve 12 will be driven to rotate. The annular sleeve 12 will first contact the glass, and the annular sleeve 12 will no longer rotate. At this time, the support rod 4 will continue to drive the suction cup 9 and the fixed cylinder 10 to rotate, and the suction cup 9 drives the separating ring 14 to rotate. The rotation of the separating ring 14 will compress the air between the annular sleeve 12, so that the air is discharged from the air outlet 13, thereby cleaning the glass. Subsequently, the suction cup 9 contacts the glass and adsorbs the glass to prevent the suction cup 9 from contacting with impurities. There is a gap between the suction cup 9 and the external environment, which makes the suction cup 9 more stable when adsorbing the glass, preventing impurities on the surface of the glass when entering the tempering furnace, and avoiding defects in the processed tempered glass.

[0036] See also Figure 5 The limiting assembly 37 includes a mounting seat 38 fixedly connected to the fixing plate 26, and a third mounting groove 39 is opened on the mounting seat 38. A push rod 40 is slidably connected in the third mounting groove 39, and one end of the push rod 40 extends through the mounting seat 38. One end of the push rod 40 located in the third mounting groove 39 is hinged with a moving rod 41 through a connecting rod, and one end of the moving rod 41 away from the push rod 40 is in contact with the rack 36, and a third spring 42 is fixedly connected between the push rod 40 and the third mounting groove 39.

[0037] The storage rack is placed on the mounting plate 29, and the driving source drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the sliding block to move. The movement of the sliding block drives the fixed plate 26 to move. The movement of the fixed plate 26 drives the mounting plate 29 to move. When the mounting plate 29 moves, the pushing block 31 contacts the bottom end of the storage rack. When the mounting plate 29 moves, the storage rack will drive the pushing block 31 to move into the mounting plate 29. The movement of the pushing block 31 drives the connecting rod 33 to rotate around the fixing seat 32. The rotation of the connecting rod 33 drives the clamping plate 34 to rotate. 34 clamps the rack so that the mounting plate 29 can drive the rack to move upward more stably, avoid the rack from shaking, and prevent the glass on the rack from falling. The rack moves close to the rotating rod 3, which is convenient for the suction cup 9 to adsorb the glass on the rack. When the rotating rod 3 drives the support rod 4 to rotate toward the glass, the rotating rod 3 rotates to drive the pawl 18 to rotate. The pawl 18 will slide on the surface of the ratchet 17, and the pawl 18 will not drive the ratchet 17 to rotate.

The glass moves toward the support frame 1. When the shelf moves to a fixed position, the glass will touch the push rod 40. The movement of the push rod 40 drives the moving rod 41 to move. The movement of the moving rod 41 drives the rack 36 to move. The rack 36 moves and will be separated from the gear 21. The glass on the shelf will be at this position. When the rotating rod 3 drives the suction cup 9 to rotate, the distance between the suction cup 9 and the glass is fixed each time, which is convenient for the suction cup 9 to adsorb the glass, so that the device can load glass of different specifications and improve the scope of use of the device.

[0038] See also Figure 1 One end of the push rod 40 located outside the mounting seat 38 contacts the glass placed on the shelf. When the push rod 40 contacts the glass, the gear 21 and the rack 36 can be disengaged through the above-mentioned transmission process, so that the glass is in a fixed position each time the material is loaded.

[0039] See also Figure 3 One end of the connecting rod 33 away from the clamping plate 34 is hinged to the side wall of the pushing block 31. The pushing block 31 moves under the action of the storage rack, thereby driving the connecting rod 33 to rotate, so that the clamping plate 34 clamps the storage rack.

[0040] See also Figure 2The upper surface of the rack 36 is lower than the upper surface of the mounting plate 29 to prevent the glass on the shelf from touching the rack 36 and causing damage to the glass.
