Description

Technical Field

[0001] This utility model relates to the field of refractory brick stacking technology, and in particular to an automatic refractory brick stacking device. Background Technology

[0002] Finished refractory brick stacking refers to the standardized operation of orderly stacking finished refractory bricks that have passed firing, cooling, and inspection, according to their specifications, physical properties, and storage and transportation requirements, on pallets, the ground, or special support structures. During the operation, the stacking pattern must be planned first. Staggered stacking is typically used to reduce gaps and enhance stability, or aligned stacking is suitable for regular, straight bricks, ensuring that each layer of bricks is tightly arranged and evenly stressed. During stacking, the height of the stack must be strictly controlled to prevent collapse due to an excessively high center of gravity, and the overall stack shape must be square and neat to facilitate subsequent transfer using forklifts and other equipment. It also facilitates counting, inventory, and protection in warehouse management, ultimately achieving safe protection and efficient space utilization of finished refractory bricks during storage and turnover.

[0003] Refractory checker bricks are a type of porous, unique brick that is stacked vertically in alignment. Existing checker bricks are mostly hexagonal in structure, with multiple vertical holes in the center and multiple vertical grooves on the outer side. They also have grooves or protrusions on the top and bottom surfaces, usually three on the same side. Due to the hexagonal shape, while the lateral orientation of the checker bricks can be restricted during transport on a conveyor line, the state and angle of the protrusions or grooves on the checker bricks cannot be controlled. This makes it difficult to accurately and seamlessly align and stack the checker bricks vertically. Utility Model Content

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Specific embodiments of the automatic refractory brick stacking equipment provided by this utility model: Please see Figures 1-7 The automatic palletizing equipment for refractory bricks includes a palletizing robot 1, with a three-jaw chuck 4 connected to the end of the palletizing robot 1.

[0024] Specifically, the palletizing robot 1 has a rotating assembly 2 installed at its end, which drives horizontal rotation. The rotating assembly 2 is connected to a housing 3, which is connected to the output end of the rotating assembly 2 via a flange. The rotating assembly 2 drives the housing 3 to rotate.

[0025] The lower side of the housing 3 is connected to the three-jaw chuck 4. The outer shell of the three-jaw chuck 4 is connected to the housing 3 through a flange. Both the lower end of the housing 3 and the upper end of the outer shell of the three-jaw chuck 4 are provided with flange rings, and the flange rings of the two are connected by bolts. The three-jaw chuck 4 rotates with the rotation of the housing 3.

[0026] The three-jaw chuck 4 includes three radially sliding and telescopic jaws 5. The bottom of the three-jaw chuck 4 is provided with a slide groove 15 for the three jaws 5 to slide radially synchronously. The three-jaw chuck 4 is provided with a threaded disk 12 that drives the jaws 5 to move radially. The lower side of the threaded disk 12 is provided with a planar thread, and the upper side of each jaw 5 is provided with a thread that meshes with the planar thread. The three jaws 5 are evenly distributed along the circumference of the threaded disk 12.

[0027] When the threaded disc 12 rotates, the threaded jaws 5 can be radially extended and retracted through the planar thread. The three jaws 5 extend and retract synchronously, providing power for clamping and releasing the refractory bricks.

[0028] The upper side of the three-jaw chuck 4 is provided with a disc 13 that is clamped between the flanges. The disc 13 is independent of the outer shell of the three-jaw chuck 4. The edge of the disc 13 is provided with through holes corresponding to the upper flange ring of the three-jaw chuck 4 and the bottom flange ring of the shell 3. While the three-jaw chuck 4 and the shell 3 are connected by bolts, the flange ring clamps and fixes the disc 13 between the flange rings.

[0029] A motor 14 that drives the threaded disc 12 to rotate is installed on the disc 13. The motor 14 is installed on the upper side of the disc 13 and extends into the lower part of the housing 3. The output shaft of the motor 14 passes through the center of the disc 13 and is connected to the threaded disc 12 by bolts at its lower end. The disc 13 supports the rotation of the output shaft of the motor 14. When the motor 14 rotates, it drives the threaded disc 12 to rotate, thereby realizing the radial synchronous extension and retraction of the chuck 5.

[0030] Each claw 5 has a vertical clamping post 6 connected to its lower side to hold the refractory brick. Specifically, the claw 5 has a pad 10 on its lower side, and the clamping post 6 is connected to the pad 10 by threads. The pad 10 has a vertical threaded hole on its lower side near the center end, and the clamping post 6 has an external thread on its upper end, thus realizing the threaded connection with the pad 10.

[0031] The clamping post 6 has a cylindrical structure, and flat surfaces 11 are provided on both sides of the lower part of the clamping post 6. By setting the flat surfaces 11, the clamping post 6 can be stably clamped by a wrench. When the wrench clamps the clamping post 6, the clamping post 6 can be easily rotated to realize the installation and removal of the clamping post 6 on the underside of the pad block 10. When the clamping post 6 is damaged, it can be replaced.

[0032] There are three clamping posts 6, which correspond one-to-one with three clamping claws 5. The three clamping posts 6 extend and retract radially in sync with the three clamping claws 5. When the clamping posts 6 are inserted into the vertical holes of the refractory bricks, the three clamping posts 6 move radially to clamp the refractory bricks, thereby driving the refractory bricks to move and transfer them from the conveying station to the stacking station.

[0033] A lifting plate 7 is located below the three-jaw chuck 4. Three vertical driving components 8 are located on the side of the lifting plate 7, evenly distributed around the outer circumference of the three-jaw chuck 4 housing. In this embodiment, the driving component 8 is a cylinder, with its extension and retraction ends connected to the lifting plate 7, driving the lifting plate 7 to move vertically.

[0034] In this embodiment, the lifting plate 7 is a triangular plate structure, passing through the center position between adjacent locking posts 6. The lifting plate 7 includes three radial portions, with an angle of 120 degrees between adjacent radial portions. The three ends of the lifting plate 7 correspond to the positions of the cylinders, and the extension and retraction ends of the cylinders are connected to the ends of the lifting plate 7 to drive the lifting plate 7 to rise and fall.

[0035] A distance sensor 9 is provided on the lower side of the three-jaw chuck 4 to detect the lifting position of the lifting plate 7. The distance sensor 9 corresponds to the lifting plate 7 and can detect the lifting distance of the lifting plate 7 relative to the three-jaw chuck 4. The state of the refractory bricks can be determined by the position of the lifting plate 7 relative to the three-jaw chuck 4. In some other embodiments, the position detection of the lifting plate 7 is also achieved by using a sensor built into the cylinder to detect the extension length of the cylinder telescopic rod instead of the distance sensor 9.

[0036] The stacking process: The conveyor line transports the qualified refractory bricks to the stacking station, where the stacking station limits the movement of the refractory bricks on the side. The palletizing robot 1 lowers the three-jaw chuck 4 to a certain height above the refractory brick, and the three clamping pins 6 extend into the three vertical holes of the refractory brick; Driven component 8 lowers lifting plate 7, such as Figure 4 As shown, the lifting plate 7 corresponds to the protrusion on the upper side of the refractory brick; as Figure 3 As shown, the lifting plate 7 does not correspond to the protrusion; the two situations cause the lifting plate 7 to descend to different heights; the distance sensor 9 detects the descent height of the lifting plate 7 to determine the above two states of the refractory brick; The palletizing effect to be achieved in this embodiment is as follows: Figure 7 As shown, the upper and lower refractory brick protrusions do not correspond to each other in order to achieve seamless vertical stacking; After inspection, the lifting plate 7 rises, and the clamping column 6 moves radially to clamp and transfer the refractory bricks; when the condition of the refractory bricks does not meet the requirements for stacking effect, the rotating assembly 2 rotates the three-jaw chuck 4 and the clamped refractory bricks by 60 degrees before placing them.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
