Description

Technical Field

[0001] The invention relates to the technical field of tile production, in particular to a steering device and a steering control method for fired bricks. Background Art

[0002] The tile production process involves first pressing powder into a shaped brick, then decorating the surface of the brick through a glaze line before firing it in a kiln. Existing tile production, when producing tiles of varying sizes, is limited by kiln width and requires different kiln loading methods for large and small tiles. This results in the need for multiple kilns to separate production processes. One kiln is dedicated to firing the arranged small tiles, while another is dedicated to firing the large tiles. This results in high investment and maintenance costs for the kiln equipment, and the production lines of the different kilns occupy a large area, severely hindering companies from increasing efficiency and reducing costs.

[0003] In the existing technology, for a production line that needs to produce products of different specifications, in order to stably support large-size products, a steering machine is mainly configured on the glaze line to meet the steering needs of tiles of different specifications. However, because the speed of the steering machine will affect the speed of the glaze line, the speed of the glaze line is limited, affecting the production capacity, and failing to meet production needs, the uneven force applied to the tiles by the middle jacking or middle drive rotation of the steering machine will also affect the quality of the tiles, causing the tiles to easily crack, crack or warp. Summary of the Invention

[0004] In response to the above defects, the purpose of the present invention is to propose a steering device for fired bricks to solve the problem that the current steering machine applies uneven force to the bricks, affecting the quality of the tiles, and the glaze line speed is affected by the steering machine, limiting production capacity.

[0005] Another object of the present invention is to propose a steering control method to ensure that bricks of different specifications can be smoothly steered using a steering device and fed into the kiln in the desired manner, thereby reducing tile quality issues and increasing production capacity.

The brick-discharging conveying component is liftably arranged on the frame and is arranged to avoid and penetrate the waiting conveying component. The conveying direction of the brick-discharging conveying component is perpendicular to the conveying direction of the waiting conveying component.

[0011] The frame is provided with a plurality of displacement detectors, which are used to detect the movement of bricks into position and send detection signals to the control device.

[0012] Preferably, the feed end of the first transport mechanism is aligned with the feed end of the second transport mechanism, and the discharge end of the first transport mechanism is aligned with the discharge end of the second transport mechanism;

[0013] The first transport mechanism and the second transport mechanism are respectively arranged horizontally on the frame.

[0014] Preferably, the integral lifting mechanism includes a base, a lifting drive motor, a transmission chain and a plurality of lifting components. The frame is movably arranged above the base through the plurality of lifting components. The lifting drive motor is connected to the transmission chain in a transmission manner, and the transmission chain is connected to the plurality of lifting components in a transmission manner.

[0015] Preferably, the brick feeding conveying assembly and the waiting conveying assembly each include a plurality of conveying rollers, and the plurality of conveying rollers are arranged at intervals;

[0016] The brick-discharging conveying assembly includes a plurality of conveying belts, and the plurality of conveying belts are arranged in parallel between the conveying rollers of the waiting conveying assembly. The plurality of conveying belts can be raised and lowered on the frame so that the conveying end surfaces of the conveying belts are higher or lower than the conveying end surfaces of the waiting conveying assembly.

[0017] Furthermore, a second lifting drive motor is provided at each of the four corner bottoms of the brick-discharging and conveying assembly, and an output end of the second lifting drive motor is connected to the bottom of the brick-discharging and conveying assembly.

[0018] Furthermore, the brick feeding conveying assembly is driven by a first driving motor to rotate the conveying roller, and the waiting conveying assembly is driven by a second driving motor to rotate the conveying roller;

[0019] The displacement detector includes a photoelectric detection switch, which is arranged above the brick feeding conveying component and the waiting conveying component. The photoelectric detection switch is used to detect the movement of the bricks.

[0023] The guide wheel is arranged on the inner side of the conveyor belt.

[0024] A method for controlling the steering of a fired brick, applied to the above-mentioned steering device for firing bricks, comprises the following steps:

[0028] Wherein: S21, when the brick enters the first transport mechanism, the first transport mechanism transports the brick, so that the moving direction of the brick changes and the forward end remains unchanged, and the brick enters the kiln horizontally;

[0029] S22, when the bricks enter the second transport mechanism, the brick-in conveying assembly and the waiting conveying assembly start to operate. After the bricks have reached the transport end face of the waiting conveying assembly, the waiting conveying assembly stops operating, the brick-out conveying assembly rises, and after the bricks leave the turning device, the brick-out conveying assembly descends.

[0030] During this period, when the end of the next brick reaches the junction of the brick-in conveying assembly and the waiting conveying assembly and the brick-out conveying assembly has not descended, the brick-in conveying assembly stops running until the transport end surface of the brick-out conveying assembly drops below the transport end surface of the waiting conveying assembly. The brick-in conveying assembly restarts and repeats the above step S22 to change the moving direction and forward end of the brick.

[0031] The technical solution provided by the present invention can have the following beneficial effects:

At the same time, the second transport mechanism is equipped with a brick feeding conveying component, a waiting conveying component and a brick discharging conveying component to change the moving direction and forward end of small-sized bricks, making it convenient for them to subsequently enter the kiln vertically in two pieces, thereby increasing production capacity. At the same time, the first transport mechanism and the second transport mechanism are distributed one above and one below, and can be lifted and lowered as a whole, effectively ensuring the overall stability, making the various parts of the bricks evenly stressed, and improving the quality of the tiles.

[0042] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0043] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] The present invention provides a diverting device for firing bricks, comprising an integral lifting mechanism 4 and a frame 1, wherein the frame 1 is mounted on the lifting end of the integral lifting mechanism 4, and the integral lifting mechanism 4 is used to lift the frame 1 in the vertical direction;

[0045] The frame 1 is equipped with a first transport mechanism 2 and a second transport mechanism 3, and the first transport mechanism 2 and the second transport mechanism 3 are distributed on the frame 1 one above and one below;

[0046] The first transport mechanism 2 has a 90° curved turning transport channel, and the first transport mechanism 2 is used for transporting bricks in a 90° turning manner;

[0047] The second transport mechanism 3 includes a brick-feeding conveying assembly 31, a waiting conveying assembly 32, and a brick-discharging conveying assembly 33. The brick-feeding conveying assembly 31 and the waiting conveying assembly 32 are arranged side by side, and the conveying direction of the brick-feeding conveying assembly 31 is consistent with the conveying direction of the waiting conveying assembly 32. The brick-discharging conveying assembly 33 is arbitrarily arranged on the frame 1 and is arranged to avoid and penetrate the waiting conveying assembly 32. The conveying direction of the brick-discharging conveying assembly 33 is perpendicular to the conveying direction of the waiting conveying assembly 32.

[0048] The frame 1 is provided with a plurality of displacement detectors, which are used to detect the movement of bricks into position and send detection signals to the control device.

[0049] In order to solve the problems existing in the prior art, the present invention proposes a diverting device for bricks to be fired. When the bricks to be transported into the kiln for firing are changed from large specifications to small specifications, specifically, from 750×1500mm to 600×1200mm bricks, the device can be used to turn the bricks into small sizes. Figure 6 As shown in the figure, two small-sized bricks are vertically fed into the kiln, and the entire frame 1 is driven to rise by the integral lifting mechanism 4, so that the bricks can enter the second transport mechanism 3, realizing the change of the moving direction of the bricks and the forward end of the bricks; when changing from small size to large size, as shown in the figure, Figure 5 As shown, the method of selecting horizontally feeding large-sized bricks into the kiln is used, and the entire frame 1 is driven down by the integral lifting mechanism 4 so that the bricks can enter the first transport mechanism 2, realizing the change of the moving direction of the bricks without changing the forward end of the bricks. Among them, the lifting end of the integral lifting mechanism 4 is installed with the frame 1, and the integral lifting mechanism 4 is used to lift the frame 1 in the vertical direction to realize the switching of the first transport mechanism 2 and the second transport mechanism 3. Through the overall lifting of the frame 1, the first transport mechanism 2 or the second transport mechanism 3 can be switched to be level with the entire glaze line, smoothly changing the moving direction of the bricks and changing or maintaining the forward end of the bricks, ensuring that the bricks enter the kiln in the required manner, reducing the waste of space inside the kiln, and reducing the impact of uneven force on the bricks themselves, ensuring the qualified rate of the obtained products. Therefore, the integral lifting mechanism 4 drives the first transport mechanism 2 and the second transport mechanism 3 to move up and down as a whole, ensuring that the bricks remain balanced during the turning process on the glaze line, solving the current problem that the glaze line speed is affected by the steering machine, production capacity is limited, and the bricks are unevenly stressed during turning.

[0050] At the same time, the second transport mechanism 3 includes a brick-feeding conveying component 31, a waiting conveying component 32 and a brick-discharging conveying component 33. The bricks pass through the brick-feeding conveying component 31 and enter the waiting conveying component 32. The brick-discharging conveying component 33, which is arranged to avoid the waiting conveying component 32, rises. Because the conveying direction of the brick-discharging conveying component 33 is perpendicular to the conveying direction of the waiting conveying component 32, the brick-discharging conveying component 33 changes the forward end of the brick. The operation of the second transport mechanism 3 ensures that the small-sized bricks can change their forward end as required after entering the steering device, which is convenient for subsequent parallel arrangement and vertical entry into the kiln.

[0051] In addition, the moving distance of the frame 1 can be determined by specific measurement to determine the lifting distance. During operation, the overall lifting mechanism 4 controls the frame 1 to rise or fall to a corresponding height, so that the first transport mechanism 2 or the second transport mechanism 3 is level with the entire glaze line, ensuring the smooth operation of the bricks.

[0052] It is worth noting that the input front end of the steering device is the input line 51, and the output rear end of the steering device is the output line 52. The control device is used to control the operation of the first transport mechanism 2, the second transport mechanism 3 and the overall lifting mechanism 4. When large-size bricks need to be produced, the control device controls the overall lifting mechanism 4 to rise and fall so that the first transport mechanism 2 is level with the entire glaze line, so that the bricks can enter the first transport mechanism 2 from the input line 51, change the moving direction of the bricks and keep the forward end of the bricks, and then leave the steering device through the output line 52 and enter the kiln in a horizontal manner; when small-size bricks need to be produced, the control device controls the overall lifting mechanism 4 to rise and fall so that the second transport mechanism 3 is level with the entire glaze line, and according to the detected brick movement position, when the brick enters the waiting conveying component 32, the waiting conveying component 32 is paused, and the brick-out conveying component 33 is controlled to rise and run, driving the bricks into the output line 52, so that the bricks can enter the kiln in a vertical manner.

[0053] Preferably, the feed end of the first transport mechanism 2 is aligned with the feed end of the second transport mechanism 3 , and the discharge end of the first transport mechanism 2 is aligned with the discharge end of the second transport mechanism 3 ;

[0054] The first transport mechanism 2 and the second transport mechanism 3 are respectively horizontally arranged on the frame 1 .

[0055] Specifically, each feed end is aligned with the discharge end to ensure that during the lifting process of the integral lifting mechanism 4, the first transport mechanism 2 and the second transport mechanism 3 can cooperate with the input line 51 and the output line 52 to prevent the steering device from colliding with the input line 51 and the output line 52 during the lifting process. In addition, the steering device is set on the glaze line to maintain the horizontal setting of the first transport mechanism 2 and the second transport mechanism 3, effectively keeping the bricks level during transportation, ensuring the qualified rate of the pattern on the brick surface, and reducing the occurrence of blurred patterns due to tilted bricks.

[0056] Preferably, the integral lifting mechanism 4 includes a base 41, a lifting drive motor 42, a transmission chain 43 and several lifting components. The frame 1 is movably arranged above the base 41 through several lifting components. The lifting drive motor 42 is connected to the transmission chain 43, and the transmission chain 43 is connected to the several lifting components.

[0057] Specifically, if Figure 1 and Figure 2As shown, the overall lifting mechanism 4 includes a lifting drive motor 42, a transmission chain 43 and a lifting assembly. The lifting drive motor 42 is connected to the lifting assembly through the transmission chain 43, that is, several lifting assemblies are operated synchronously without changing the horizontal state of the steering device, ensuring that the bricks on the steering device can remain horizontal, so that each part of the brick is evenly stressed, effectively ensuring the pass rate and quality of the tiles.

[0058] Wherein, the lifting assembly is arranged at each outer corner of the bottom of the frame 1, effectively dispersing stress to ensure subsequent adjustment of the lifting of the frame 1, the lifting assembly includes a screw rod 44 and a chain plate 45, the output end of the lifting drive motor 42 is connected to a sprocket, the lifting drive motor 42 is connected to the transmission chain 43 through the sprocket, the transmission chain 43 is connected to the screw rod 44 through the chain plate 45, the screw rod 44 is provided with a matching nut, the nut is fixedly connected to the frame 1, specifically, the lifting drive motor 42 drives the sprocket to rotate, and the sprocket is connected to the The transmission chain 43 is connected in a transmission manner. The rotation of the sprocket drives the transmission chain 43 and then drives the chain disc 45 of each lifting component to rotate. The rotation of the chain disc 45 drives the screw rod 44 to rotate, and then drives the nut to move in the vertical direction, that is, drives the frame 1 to rise and fall. At the same time, the screw rod 44 can convert the rotational motion into linear motion, accurately control the linear displacement, that is, can accurately control the horizontality of the entire device. Several screw rods 44 are driven by the same transmission chain 43 and rotate synchronously. The lifting height of each point is completely consistent, so that the first transport mechanism 2 and the second transport mechanism 3 can maintain horizontal up and down movement. Compared with using a chain to drive up and down movement at each point, using the transmission chain 43 to drive the frame 1 to rise and fall effectively reduces the elastic deformation, pitch error and tension difference of the chain itself, and better ensures the horizontality of the transport surface of the first transport mechanism 2 and the second transport mechanism 3.

[0059] Additionally, the steering device can be initially leveled using a laser level.

[0060] Preferably, the brick feeding conveying assembly 31 and the waiting conveying assembly 32 each include a plurality of conveying rollers, and the plurality of conveying rollers are arranged at intervals;

[0061] The brick-discharging conveying assembly 33 includes a plurality of conveying belts 331, and the plurality of conveying belts 331 are arranged in parallel between the conveying rollers of the waiting conveying assembly 32. The plurality of conveying belts 331 can be raised and lowered on the frame 1 so that the conveying end surface of the conveying belt 331 is higher or lower than the conveying end surface of the waiting conveying assembly 32.

[0062] Specifically, if Figure 3As shown, when the bricks completely enter the waiting conveying component 32, the brick-discharging conveying component 33 rises, and the transport end surface of the brick-discharging conveying component 33 is higher than the transport end surface of the waiting conveying component 32. The bricks are supported by the brick-discharging conveying component 33 and move into the output line 52 and then into the kiln, controlling the moving direction and forward end of the bricks.

[0063] The brick feeding conveying assembly 31, the waiting conveying assembly 32 and the brick discharging conveying assembly 33 respectively include corresponding drive connection structures, which can be used to drive a number of conveying rollers to rotate, or to drive a number of conveying belts 331 to rotate. The drive connection structure is existing technology and will not be described here.

[0064] Furthermore, a second lifting drive motor 341 is provided at each of the four corner bottoms of the brick-discharging conveying assembly 33 , and an output end of the second lifting drive motor 341 is connected to the bottom of the brick-discharging conveying assembly 33 .

[0065] The four second lifting drive motors 341 operate synchronously to drive the brick delivery conveying assembly 33 to rise and fall horizontally as a whole, thereby making the conveying belt 331 higher or lower than the transport end surface of the waiting conveying assembly 32, ensuring that the bricks can be transported horizontally to the output line 52, while effectively dispersing stress to ensure smooth transportation of bricks.

[0066] Furthermore, the brick feeding conveying assembly 31 is driven by a first driving motor 311 to rotate the conveying rollers, and the waiting conveying assembly 32 is driven by a second driving motor 321 to rotate the conveying rollers;

[0067] The displacement detector includes a photoelectric detection switch, which is arranged above the brick feeding conveying component 31 and the waiting conveying component 32. The photoelectric detection switch is used to detect the movement of the bricks.

[0068] Specifically, when the first brick enters the brick-feeding conveying assembly 31 and reaches the waiting conveying assembly 32 as a whole, under the control of the photoelectric detection switch, the second drive motor 321 stops driving, and the waiting conveying assembly 32 stops running. After the brick-discharging conveying assembly 33 conveys the brick to the output line 52 and descends to a level lower than the transport end surface of the waiting conveying assembly 32, the second drive motor 321 drives the waiting conveying assembly 32 to restart running. In the above process, when the end of the second brick reaches the junction of the brick-feeding conveying assembly 31 and the waiting conveying assembly 32 and the brick-discharging conveying assembly 33 has not descended, the first drive motor 311 stops driving, and the brick-feeding conveying assembly 31 stops running. After the brick-discharging conveying assembly 33 descends to a level lower than the transport end surface of the waiting conveying assembly 32, the first drive motor 311 drives the brick-feeding conveying assembly 31 to restart running. Subsequently, the brick-feeding conveying assembly 31 and the waiting conveying assembly 32 jointly convey the second brick to the waiting conveying assembly 32 as a whole. The above process is repeated to achieve the change of the moving direction and forward end of the brick.

[0069] Furthermore, the control device includes a controller, and the controller is electrically connected to the first drive motor 311, the second drive motor 321, the second lifting drive motor 341 and the photoelectric detection switch.

[0070] Specifically, under the control of the controller and in coordination with the photoelectric detection switch, the operating states of the first drive motor 311, the second drive motor 321 and the second lifting drive motor 341 are changed to ensure the horizontal and stable transportation of the second transport mechanism 3 and realize the automatic steering of small-sized bricks.

[0071] Preferably, the first transport mechanism 2 includes an inner pulley group 23, a conveyor belt 21 and an outer pulley group 24, and several conveyor belts 21 are arranged in a 90° arc array, and the conveyor belts 21 are respectively installed on the pulleys of the inner pulley group 23 and the pulleys of the outer pulley group 24.

[0072] Specifically, if Figure 4 As shown, several conveyor belts 21 are arranged in a 90° arc array, so that the bricks change their moving direction under the drive of the conveyor belts 21 and maintain the forward end. It is worth noting that the rotation speed of the inner pulley set 23 is lower than the rotation speed of the outer pulley set 24. The rotation speeds of the inner pulley set 23 and the outer pulley set 24 are different. The inner pulley set 23 is located on the inner side of the arc structure. The lateral force generated by the speed difference allows the bricks to turn smoothly along the arc path, effectively avoiding deformation and surface damage of the bricks.

[0073] Furthermore, the first transport mechanism 2 further includes a circular arc bracket 22 and a plurality of guide wheels 25, and the inner pulley set 23 and the outer pulley set 24 are rotatably connected to the ends of the circular arc bracket 22;

[0074] The guide wheel 25 is disposed on the inner side of the conveyor belt 21 .

[0075] Specifically, the inner pulley set 23 and the outer pulley set 24 are rotatably connected to the end of the arc bracket 22, driving the conveyor belt 21 to rotate, and then driving the bricks to turn smoothly, thereby achieving the purpose of changing the moving direction of the bricks while ensuring transmission stability.

[0076] Among them, the arc bracket 22 is adapted to the right-angle structure of the second transport mechanism 3, and the two ends of the arc bracket 22 are aligned with the feed end and the discharge end of the second transport mechanism 3 to ensure that the bricks can smoothly enter the steering device and prevent the steering device from being damaged by collision with other structures during the lifting process.

[0077] In addition, the guide wheel 25 is arranged on the inner side of the transmission belt, that is, the inner side of the arc structure. The guide wheel 25 ensures that the transmission belt runs along the required turning radius and plays a certain guiding role to prevent the direction of the conveyor belt 21 from deviating, ensuring that the bricks thereon can move in the required direction.

[0078] The present invention also provides a steering control method for fired bricks, which is applied to any of the above-mentioned steering devices for fired bricks, and comprises the following steps:

[0079] S1, the overall lifting mechanism drives the frame to move in the vertical direction;

[0080] Among them, when the product size changes from large to small, the overall lifting mechanism drives the frame to rise as a whole, so that the bricks enter the second transport mechanism; when the product size changes from large to small, the overall lifting mechanism drives the frame to fall as a whole, so that the bricks enter the first transport mechanism;

[0081] S2, the first transport mechanism or the second transport mechanism operates to change the moving direction of the brick and controls the forward end of the brick as required;

[0082] Wherein: S21, when the brick enters the first transport mechanism, the first transport mechanism transports the brick, so that the moving direction of the brick changes and the forward end remains unchanged, and the brick enters the kiln horizontally;

[0083] S22, when the bricks enter the second transport mechanism, the brick-in conveying assembly and the waiting conveying assembly start to operate. After the bricks have reached the transport end face of the waiting conveying assembly, the waiting conveying assembly stops operating, the brick-out conveying assembly rises, and after the bricks leave the turning device, the brick-out conveying assembly descends.

[0084] During this period, when the end of the next brick reaches the junction of the brick-in conveying assembly and the waiting conveying assembly and the brick-out conveying assembly has not descended, the brick-in conveying assembly stops running until the transport end surface of the brick-out conveying assembly drops below the transport end surface of the waiting conveying assembly. The brick-in conveying assembly restarts and repeats the above step S22 to change the moving direction and forward end of the brick.

[0085] The whole process is as follows: large-sized bricks are pressed, specifically 750×1500; small-sized bricks, specifically 600×1200, are transported through the glaze line and enter the diverter. When the product to be produced changes from large to small specifications, the brick feeding method is changed from horizontal to vertical, and the frame 1 rises. Figure 6 As shown, the second transport mechanism 3 rises until it reaches the corresponding position, and the bricks move toward the second transport mechanism 3, so that two bricks are vertically fed into the large kiln; when the product to be produced changes from small specifications to large specifications, the bricks are fed into the kiln horizontally instead of vertically, and the frame 1 descends, as shown. Figure 5 As shown, the lower transport mechanism is lowered to a corresponding position and connected to the input line 51, and the bricks are then fed into the kiln horizontally.

[0086] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily conceive of other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
