Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic ceramic tile production, and in particular to a ceramic tile delivery system. BACKGROUND

[0002] As one of the basic materials in the construction industry, the production and processing of ceramic tiles have an increasing demand for automation technology. With the rapid development of the construction industry, the production efficiency and quality control of ceramic tiles have become key factors in industry competition. The application of automatic production technology makes the production process of ceramic tiles more efficient, reduces labor costs, and improves product consistency and quality. In the automatic production technology of ceramic tiles, the delivery system of ceramic tiles is an important part connecting various production links, and its performance directly affects the smoothness and stability of the entire production line.

[0003] In existing ceramic tile production lines, the right-angle lifting and turning device for delivering ceramic tiles is a key equipment for transferring ceramic tiles between different conveying platforms. This device is usually composed of a lifting frame and a tile pushing cylinder, and its working principle is to convey the ceramic tiles to the lifting frame, and then turn and convey the ceramic tiles to the side conveying line frame through the lifting of the lifting frame and the pushing of the tile pushing cylinder. This design achieves automatic turning and delivery of ceramic tiles to some extent, but also has some technical limitations.

[0004] The right-angle lifting and turning device of the prior art has some defects in actual application. First, the device needs to use two cylinders to complete the turning and delivery of ceramic tiles, which not only increases the complexity of the system, but also increases the difficulty of maintenance and repair. The frequent action of the cylinder can cause wear and tear and failure, thereby affecting the stability and reliability of the entire production line. Second, the frequent action of the cylinder can also produce a lot of noise and energy consumption, which is a problem that cannot be ignored for modern industrial production that pursues environmental protection and energy saving; third, the ceramic tiles in the conventional production line need to stop before turning and delivering, which affects the continuity and efficiency of the production line.

[0005] In addition to the high failure rate of the cylinder, the control accuracy of the ceramic tile delivery system of the prior art during the turning of the ceramic tiles also needs to be improved. Since the ceramic tiles need to go through the lifting and pushing steps during the turning process, it may cause the ceramic tiles to deviate or be unstable during the turning process, affecting the quality and production efficiency of the ceramic tiles. In addition, the existing device may not be able to achieve flexible adjustment when handling ceramic tiles of different sizes and weights, limiting the adaptability and flexibility of the production line.

[0006] In summary, the delivery system in the existing automated tile production technology has multiple problems, including but not limited to high cylinder failure rate, high energy consumption and noise, insufficient control precision, incoherent delivery, and poor adaptability. These problems not only affect the production efficiency and quality of tiles, but also increase the production cost and maintenance difficulty. Therefore, the existing technology needs to be improved to improve the overall performance and reliability of automated tile production. Utility model content

[0024] In an optional embodiment, the roller mechanism further comprises a support;

[0025] One end of the support is connected with the roller shaft, and the other end is connected with the upper surface of the lifting frame.

[0026] In an optional embodiment, based on the height of the support, when the lifting frame is lifted in the lifting space by the lifting cylinder towards the conveying belt at the upper end, the height of the upper cutting surface of the rubber wheel can be higher than the upper end surface of the conveying belt, and the bottom surface of the target ceramic tile delivered by the first conveying platform can contact the rubber wheel and be conveyed to the second conveying platform by inertia;

[0042] Some embodiments of the present application will be described in detail with reference to the drawings. The following embodiments and features of the embodiments can be combined with each other without conflict.

[0043] Embodiment 1

[0044] Reference Figure 1 In this embodiment, a ceramic tile delivery system 100 is provided, comprising a first conveying platform 1 and a second conveying platform 2 arranged in conveying direction, and a lifting device 3 and a direction-changing conveying platform 4 arranged between the first conveying platform 1 and the second conveying platform 2; wherein the conveying direction of the direction-changing conveying platform 4 is different from the conveying direction of the first conveying platform 1 and the second conveying platform 2.

[0045] The lifting device 3 can control the target ceramic tile delivered by the first conveying platform 1 to be conveyed in a straight line direction on the surface of the second conveying platform 2, or to be conveyed in a non-straight line direction on the direction-changing conveying platform 4, by adjusting the height.

[0046] The ceramic tile delivery system 100 described above realizes efficient transfer of ceramic tiles in different conveying directions through the first conveying platform 1, the second conveying platform 2, the lifting device 3 and the direction-changing conveying platform 4. Each component of the system has a clear function and improvement process in structure to solve the deficiencies in the prior art.

[0047] The target ceramic tile refers to a specific ceramic tile that is delivered by the first conveying platform 1 to the lifting device 3 and then conveyed in different directions in the automated production process. These ceramic tiles will be conveyed to the second conveying platform 2 or the direction-changing conveying platform according to the control of the system to realize straight line or non-straight line conveying.

[0048] The first conveying platform 1 and the second conveying platform 2 are arranged in conveying direction, forming a straight line conveying path for ceramic tiles from production to packaging. This arrangement simplifies the conveying process of ceramic tiles and reduces the complexity of the conveying process. The introduction of the direction-changing conveying platform 4, whose conveying direction is different from that of the first and second conveying platforms 2, provides a non-straight line conveying option for ceramic tiles and increases the flexibility of the production line.

[0049] As mentioned above, the conveying direction of the first conveying platform 1 and the second conveying platform 2 can be the same, forming a straight line conveying direction for the target ceramic tile.

[0050] The variable direction conveying platform 4 has a conveying direction different from the straight conveying direction, and the conveying direction can intersect with the straight conveying direction to form a conveying direction with a certain angle for the ceramic tiles. For example, in an embodiment, the conveying direction of the variable direction conveying platform 4 forms a 90° angle with the conveying direction of the first conveying platform 1 and the second conveying platform 2, thereby forming a right-angle non-straight conveying direction. In addition, the angle can also be 120°, 150°, etc.

[0051] Therefore, the ceramic tile delivery system 100 in the embodiment can form at least two directions of delivery for the target ceramic tile: (1) a straight conveying direction: conveying from the first conveying platform 1 to the second conveying platform 2; and (2) a non-straight conveying direction: conveying from the first conveying platform 1 to the variable direction conveying platform 4.

[0052] It can be seen that the target ceramic tile is output by the first conveying platform 1, and further can be transferred to the second conveying platform 2 by the lifting device 3 for straight conveying direction conveying or to the variable direction conveying platform 4 for non-straight conveying direction conveying according to production requirements.

[0053] The lifting device 3 described above is the core of the system, which controls the conveying direction of the ceramic tile by adjusting the height. This design replaces the traditional right-angle lifting and turning device which needs two cylinders to push, reduces the frequency of cylinder action, and thus reduces the failure rate. The precise control ability of the lifting device 3 reduces the position deviation of the ceramic tile during turning, improves the conveying accuracy of the ceramic tile, and thus improves the product quality.

[0054] In terms of connection relationship, the lifting device 3 is connected with the first conveying platform 1 and the variable direction conveying platform 4, and realizes the transfer of the ceramic tile between different platforms through lifting action. This connection mode constitutes an efficient ceramic tile delivery system 100, which can solve the problems of high cylinder failure rate, high energy consumption, and high noise in the prior art. At the same time, the structure of the lifting device 3 is relatively simple, which is convenient for inspection and maintenance, simplifies the maintenance work, and reduces the maintenance cost.

[0055] It should be noted that in the conventional production line, the ceramic tile conveying line is usually narrow and does not have the condition of long-distance buffer transportation, and the width of the conveying platform is also relatively limited, basically matching the size of the ceramic tile. In this background, the ceramic tile delivery system 100 provided in this embodiment can overcome the defects in the conventional technology and achieve rapid and effective redirection of the ceramic tile under the condition of limited conveying platform width. Compared with the conventional technology, the delivery speed is slow, or additional improvement of the production line and widening of the conveying table are needed, while the system does not need to widen the conveying table for modification, and can achieve the purpose of rapid redirection, significantly improving the conveying efficiency and space utilization. This innovative design not only saves space, but also improves the flexibility and economy of operation, providing a more efficient and compact solution for logistics transportation in narrow spaces. In addition, the design of the system also considers the stability, adaptability and continuity of the ceramic tile during transportation. Through the precise control of the lifting device 3, the transfer of the ceramic tile between different conveying platforms is more stable, reducing the risk of damage to the ceramic tile, and the delivery process is more smooth, avoiding the impact of stop on production efficiency. At the same time, the system can adapt to ceramic tiles of different sizes and weights, improving the adaptability and flexibility of the production line.

[0056] It should be noted that the system provided in this embodiment can sort and / or separate ceramic tiles according to production needs in addition to conveying, delivering and transferring ceramic tiles to designated locations.

[0057] In summary, the ceramic tile delivery system 100 provides a more efficient, reliable and environmentally friendly automatic production solution for ceramic tiles through its structural design and connection relationship, effectively solving many problems in the prior art.

[0058] Embodiment 2

[0059] Reference Figure 2 In this embodiment, based on the above-mentioned embodiment 1, a ceramic tile delivery system 100 is provided, the vertical height of the conveying surface of the second conveying platform 2 is higher than the vertical height of the conveying surface of the first conveying platform 1. The vertical height of the conveying surface of the redirection conveying platform 4 is not higher than the vertical height of the conveying surface of the first conveying platform 1. The top view structure of the ceramic tile delivery system 100 is shown in Figure 3 .

[0060] As mentioned above, the vertical height of the conveying surface of the second conveying platform 2 is higher than the conveying surface of the first conveying platform 1. Such a setting allows the ceramic tile to transition more smoothly to the second conveying platform 2 by using gravity when delivered from the first conveying platform 1 to the second conveying platform 2, reducing the impact force of the ceramic tile during transfer and reducing the risk of damage.

[0061] The conveying direction of the change direction conveying platform 4 is different from the first and second conveying platforms 2, providing a non-linear conveying option for the ceramic tiles. The conveying surface of the change direction conveying platform 4 is not higher than the first conveying platform 1 in the vertical direction, which helps the ceramic tiles to be effectively transferred to the change direction conveying platform 4 for non-linear conveying without increasing additional height, maintaining the compactness of the production line and reducing space occupation.

[0062] As the core component of the system, the lifting device 3 controls the conveying direction of the ceramic tiles by adjusting the height. When the ceramic tiles need to be conveyed to the second conveying platform 2, the lifting device 3 lifts the ceramic tiles to a sufficient height to form a slope, enabling a smooth transition to the higher second conveying platform 2. When the ceramic tiles need to be conveyed to the change direction conveying platform 4, the lifting device 3 can be lowered to a lower height, enabling the ceramic tiles to be smoothly transferred to the change direction conveying platform 4 with a different conveying direction.

[0063] The advantage of this design is to improve the flexibility and efficiency of ceramic tile delivery. By precisely controlling the conveying height of the ceramic tiles, the system can adapt to different production needs, whether it is linear conveying or non-linear change direction conveying. At the same time, this design also helps to reduce the breakage of ceramic tiles during conveying, improving the overall performance of the production line.

[0064] Solves the stability and breakage problems that may be encountered when transferring ceramic tiles between conveying platforms of different heights in the prior art. By optimizing the height difference of the conveying platforms, the system can more effectively handle the transfer of ceramic tiles, especially when the conveying direction needs to be changed, reducing the impact and breakage of ceramic tiles due to height changes.

[0065] In summary, the ceramic tile delivery system 100 provides a more stable and efficient ceramic tile conveying solution through the height difference and control of the lifting device 3, which helps to improve the operating efficiency and product quality of the ceramic tile production line.

[0066] Further, with reference to Figure 4 and Figure 5 , the lifting device 3 includes a roller mechanism 31, a lifting frame 32 and a lifting cylinder 33 arranged from top to bottom; the roller mechanism 31 includes a roller shaft 311 arranged on the lifting frame 32 and a rubber roller 312 arranged on the roller shaft 311; the lifting cylinder 33 is connected with the lifting frame 32 and can control the lifting frame 32 to lift or lower the upper end roller mechanism 31.

[0067] The aforementioned roller mechanism 31 includes a roller shaft 311 arranged on the lifting frame 32 and a rubber roller 312 arranged on the roller shaft 311. This design allows the ceramic tile to smoothly transition during lifting by the rolling of the rubber roller 312, reducing friction between the ceramic tile and the conveying platform and lowering the risk of breakage.

[0068] The lifting frame 32 is the main load-bearing structure of the lifting device 3, which is controlled by the lifting cylinder 33 to achieve lifting or lowering. The design of the lifting frame 32 allows the ceramic tile to adjust the height between different conveying platforms to adapt to different conveying needs.

[0069] In the ceramic tile delivery system 100, the rubber roller 312 is a key component of the lifting device 3, and its material and friction characteristics are crucial to the performance of the entire system. The material of the rubber roller 312 is usually selected to have good wear resistance, chemical corrosion resistance, high strength, high elasticity, low pressure resistance, strong shock absorption, and tear resistance to ensure its stability and durability during ceramic tile conveying. For example, the material of the rubber roller 312 can be polyurethane (PU), which has high strength and wear resistance, and is relatively light in weight, easy to process, and is the preferred rubber material in many industrial equipment.

[0070] In terms of friction, the friction coefficient of the rubber roller 312 is an important parameter for evaluating its friction behavior, which directly affects the friction performance and service life of the rubber roller 312. The friction coefficient is affected by many factors, including material properties, wheel and ground material, lubricant, environmental temperature, and load. In the ceramic tile delivery system 100, the friction of the rubber roller 312 needs to be large enough to prevent the ceramic tile from slipping during conveying and to generate a certain amount of friction when the target ceramic tile contacts the surface of the rubber roller 312, while not being too large to cause unnecessary energy consumption and wear.

[0071] It should be noted that the target ceramic tile has certain requirements for friction when conveying in different directions. The rubber roller 312 in this embodiment can be a passive wheel, i.e., it does not generate active rotational power. When conveying in a straight line, the target ceramic tile is conveyed from the first conveying platform 1 through the rubber roller 312 on the lifting frame 32 to the second conveying platform 2; when conveying in a non-straight line, the target ceramic tile is conveyed from the first conveying platform 1 to the rubber roller 312 on the lifting frame 32 and reaches the turning conveying platform 4, achieving non-straight line conveying. At this time, the ceramic tile is affected by two friction forces, resulting in a decrease in the speed of straight line conveying to 0, while it can be conveyed in a non-straight line driven by the belt of the turning conveying platform 4. The two friction forces are: the friction between the bottom surface of the ceramic tile and the rubber roller 312, and the friction between the bottom surface of the ceramic tile and the surface of the turning conveying platform 4.

[0072] To meet the needs of the tile delivery system 100, the design of the rubber wheel 312 needs to consider the friction coefficient between its contact surface and the tile to ensure that the tile can smoothly transition between different conveying platforms. By reasonably selecting materials, using lubricants, controlling environmental temperature, etc., the friction coefficient of the wheel can be changed to improve the motion efficiency and service life of the tile delivery system 100. For example, by selecting a polyurethane material with appropriate hardness and surface roughness, the friction coefficient of the rubber wheel 312 can be adjusted to adapt to different working environments and tile characteristics.

[0073] As mentioned above, the lifting frame 32 is the main load-bearing structure of the lifting device 3, which is raised or lowered by the control of the lifting cylinder 33. The design of the lifting frame 32 allows the tile to adjust the height between different conveying platforms to adapt to different conveying needs and switch flexibly according to instructions.

[0074] The lifting device 3 improves the stability and conveying efficiency of the tile during the conveying process through the design of the roller mechanism 31. The introduction of the roller mechanism 31 reduces the friction and impact of the tile during the conveying process, thereby reducing the possibility of tile breakage. Through the combination of the roller mechanism 31, the lifting frame 32 and the lifting cylinder 33, a lifting device 3 is formed that can smoothly transition the tile between different height conveying platforms. This structure not only improves the conveying efficiency of the tile, but also enhances the stability and reliability of the system.

[0075] The advantage of this structure is that it can reduce the breakage of the tile during the conveying process, improve the conveying efficiency, reduce the energy consumption, and simplify the maintenance work of the system by reducing the use of the cylinder.

[0076] The lifting device 3 solves the stability and breakage problems that may occur when the tile is transferred between different height conveying platforms in traditional technology. By optimizing the structure of the lifting device 3, the system can more effectively handle the transfer of the tile, especially when the conveying direction needs to be changed, which can reduce the impact and breakage of the tile due to height changes.

[0077] Furthermore, the lifting cylinder 33 can be controlled automatically. For example, in the tile delivery system 100 of this example, the control device of the lifting cylinder 33 is a key component, consisting of a cylinder control valve, a position sensor, a control system (such as a PLC or microcontroller), a human-machine interface (HMI), and a safety mechanism. The cylinder control valve is responsible for controlling the inflation and deflation of the lifting cylinder 33, achieving the lifting and lowering of the lifting frame 32. The position sensor is installed on the lifting frame 32, which is used to monitor and feedback the current position of the lifting frame 32 in real time, ensuring that the lifting frame 32 can accurately reach the predetermined height. The control system acts as the brain of the entire device, controlling the opening and closing of the cylinder control valve according to the feedback of the position sensor and the instructions input by the operator through the HMI, to achieve precise control of the lifting frame 32. The HMI allows the operator to set parameters such as the target height of the lifting frame 32, and start, stop and monitor the lifting process. The safety mechanism includes an emergency stop button, overload protection and limit switches to prevent the lifting frame 32 from exceeding the safe working range or automatically stopping in case of failure.

[0078] The control principle includes initializing the system, receiving the operator's instructions, determining the height that the lifting frame 32 needs to reach, controlling the cylinder to rise, receiving position information through the position sensor, stopping the rise when the target height is reached, controlling the cylinder to descend if a change in direction is required, until the rubber wheel 312 contacts the change direction conveying platform 4, and returning to the initial position after the conveying is completed. Throughout the process, the safety mechanism continuously monitors to ensure safe operation. Through this design, the control device of the lifting cylinder 33 can accurately control the transfer of tiles between different conveying platforms, improving the automation level and efficiency of the tile delivery system 100.

[0079] Further, the rolling direction of the rubber wheel 312 in the roller mechanism 31 is consistent with the advancing direction of the target tile delivered by the first conveying platform 1.

[0080] As mentioned above, the rolling direction of the rubber wheel 312 is consistent with the advancing direction of the target tile delivered by the first conveying platform 1. This design improvement ensures the stability of the tiles during conveying, while reducing friction and wear caused by inconsistent directions when the target tile is conveyed in a straight line by inertia, improving conveying efficiency and tile safety.

[0081] This structure has the advantages of reducing tile breakage during conveying, improving conveying efficiency, reducing energy consumption, and simplifying maintenance work by reducing the use of cylinders. At the same time, the rolling direction of the rubber wheel 312 is consistent with the advancing direction of the tiles, which helps to reduce the resistance of the tiles during the change of direction, making the change of direction smoother and improving the accuracy and efficiency of the change of direction of the tiles.

[0082] Example 3

[0083] In this embodiment, based on the above embodiment 2, a ceramic tile delivery system 100 is provided, the variable direction conveying platform 4 is provided with a fixed table 5 below; the lifting device 3 further comprises a swing shaft 34; the lifting frame 32 is movably connected with the swing shaft 34, and is hinged with the fixed table 5 below the variable direction conveying platform 4 through the swing shaft 34.

[0084] As mentioned above, the fixed table 5 is arranged below the variable direction conveying platform 4, serving as a stable base for the lifting device 3. It provides a fixed connection point for the lifting frame 32, which helps to reduce the vibration and deviation that may occur during the conveying of ceramic tiles.

[0085] The lifting device 3 comprises a roller mechanism 31, a lifting frame 32 and a lifting cylinder 33. The roller mechanism 31 is composed of a roller shaft 311 and a rubber wheel 312, and the rolling direction of the rubber wheel 312 is consistent with the advancing direction of the ceramic tiles, which helps to ensure smooth transition of the ceramic tiles during conveying.

[0086] The lifting frame 32 is movably connected with the swing shaft 34, and is hinged with the variable direction fixed table 5 through the swing shaft 34. This design allows the lifting frame 32 to swing within a certain angle range, so as to adapt to the height difference and direction change of the ceramic tiles between different conveying platforms.

[0087] Through the introduction of the swing shaft 34, the lifting frame 32 can swing around the swing shaft 34, so as to not only vertically lift the lifting frame 32 itself and the rubber wheel 312 at its upper end, but also horizontally fine-tune, which increases the flexibility and adaptability of the ceramic tile delivery. This structure constitutes a lifting device 3 that can realize smooth transition of ceramic tiles between different height and direction conveying platforms, while maintaining the stability of the system, reducing the damage of ceramic tiles during conveying, improving the conveying efficiency, reducing the energy consumption, and simplifying the maintenance work of the system by reducing the use of cylinders.

[0088] In this embodiment, the stability and damage problems that may occur when ceramic tiles are transferred between different height conveying platforms in the prior art are solved. By optimizing the structure of the lifting device 3, the system can more effectively handle the transfer of ceramic tiles, especially when the conveying direction needs to be changed, the impact and damage of ceramic tiles due to height change can be reduced.

[0089] For example, when the ceramic tiles need to be conveyed from the first conveying platform 1 to the second conveying platform 2, the lifting cylinder 33 controls the lifting frame 32 to rise, so that the rubber wheel 312 smoothly lifts the ceramic tiles to the height of the second conveying platform 2. When the ceramic tiles need to be transferred to the variable direction conveying platform 4, the lifting frame 32 swings through the swing shaft 34, so that the rubber wheel 312 contacts the conveying surface of the variable direction conveying platform 4, thereby realizing the transfer of the ceramic tiles.

[0090] In summary, the ceramic tile delivery system 100 provides a more stable and efficient ceramic tile conveying solution through the design of its lifting device 3, which helps to improve the operating efficiency and product quality of the ceramic tile production line.

[0091] Further, the direction-changing conveying platform 4 includes at least one set of conveying assemblies 41; each conveying assembly 41 includes two rotating wheels 411 and a conveying belt 412; at least one of the rotating wheels 411 is a driving wheel; the conveying belt 412 forms a closed loop around the two rotating wheels 411 and can move synchronously under the drive of the rotating wheels 411.

[0092] The direction-changing conveying platform 4 described above is a key component in the system responsible for realizing the non-linear direction conveying of ceramic tiles, including at least one set of conveying assemblies 41, which work together to realize the turning conveying of ceramic tiles. Each set of conveying assemblies 41 is composed of two rotating wheels 411 and a conveying belt 412. The rotating wheels 411 are the core of the conveying assemblies 41, at least one of which is a driving wheel responsible for driving the movement of the conveying belt 412.

[0093] For example, two sets of conveying assemblies 41 can be symmetrically and side-by-side arranged, and the target ceramic tile can be more stably conveyed on the conveying belts 412 of the two sets of conveying assemblies 41.

[0094] The conveying belt 412 forms a closed loop around the two rotating wheels 411 and can move synchronously under the drive of the rotating wheels 411. This design ensures the stable conveying of ceramic tiles on the direction-changing conveying platform 4.

[0095] The rubber wheels 312 and the lifting frame 32 in the lifting device 3 do not contact the conveying belt 412 and the rotating wheels 411, and their lifting does not affect the movement of the conveying belt 412 and the rotating wheels 411.

[0096] In this embodiment, the design of the conveying assemblies 41 is introduced to improve the structure of the direction-changing conveying platform 4. This design makes the ceramic tile more stable during turning, reducing the possibility of sliding or tilting during turning. This structure constitutes a direction-changing conveying platform 4 that can realize the stable conveying of ceramic tiles in different directions, improving the flexibility and efficiency of ceramic tile delivery. It can improve the stability of ceramic tiles during turning and conveying, reduce the risk of ceramic tile breakage, improve conveying efficiency, and ensure the continuity and uniformity of ceramic tile conveying through the closed-loop design of the conveying belt 412.

[0097] Further, in the conveying assembly 41, two rotating wheels 411 and conveying belts 412 on the upper and lower sides form a lifting space 413; the lifting frame 32 is arranged in the lifting space 413 and can move between the two conveying belts 412 in the lifting space 413 under the action of the lifting cylinder 33.

[0098] The conveying assembly 41 is composed of two rotating wheels 411 and a conveying belt 412, at least one of which is a driving wheel responsible for driving the movement of the conveying belt 412. This design allows the tiles to be diverted on the diverting conveying platform 4.

[0099] The lifting space 413 is formed by the two rotating wheels 411 and the conveying belts 412 on both sides, providing a passageway for the lifting frame 32. The lifting frame 32 is arranged in the lifting space 413 and can move within the space without affecting the movement of the conveying assembly 41. This space design allows the lifting frame 32 to move between the two conveying belts 412 under the action of the lifting cylinder 33.

[0100] In this embodiment, the concept of lifting space 413 is introduced to improve the conveying method of tiles on the diverting conveying platform 4. The lifting frame 32 can move within the lifting space 413, making the diversion of tiles more flexible and efficient. This structure constitutes a diverting conveying platform 4 that can stably convey tiles at different heights and directions, while maintaining the compactness and stability of the system. It can improve the stability of tiles during the diversion process, reduce the risk of tile breakage, improve the conveying efficiency, and ensure the continuity and uniformity of tile conveying through the design of the lifting space 413.

[0101] The problem of insufficient stability and low conveying efficiency of tiles during diversion in conventional technology is solved. By optimizing the design of the conveying assembly 41 and the lifting space 413, the system can more effectively handle the diversion of tiles, especially when the conveying direction needs to be changed, reducing the impact and damage of tiles due to diversion.

[0102] Further, referring to Figure 6 , the lifting frame 32 is provided with multiple sets of roller mechanisms 31; the roller mechanisms 31 are arranged at corresponding positions of the lifting frame 32 that are different from the conveying belts 412, so that the rubber wheels 312 in the roller mechanisms 31 can contact the bottom surface of the target tile through the space at both ends of the conveying belt 412 (the space parallel to the length direction of the conveying belt 412) when moving upward. The side view and top view are shown in Figures 7-9 .

[0103] As mentioned above, the lifting frame 32 can be provided with multiple sets of roller mechanisms 31, which are distributed at different positions of the lifting frame 32 and at corresponding positions different from the conveying belts 412. This design allows the lifting frame 32 to adjust the height within the lifting space 413, while the roller mechanisms 31 assist in the diversion of tiles by contacting the bottom surface of the tiles.

[0104] The position of the rubber wheels 312 on the lifting frame 32 is designed such that the rubber wheels 312 can contact the bottom surface of the tiles through the space between the two ends of the conveying belt 412 when the lifting frame 32 moves upward. This arrangement helps to provide additional support and guidance during the tile turning process, ensuring smooth transition of the tiles from the first conveying platform 1 to the turning conveying platform 4.

[0105] By increasing the number of roller mechanisms 31 and optimizing their layout, the tile turning process on the turning conveying platform 4 is improved. This design reduces friction and wear during turning, improves the stability and efficiency of turning.

[0106] For example, the first conveying platform 1 and the second conveying platform 2 are arranged in a straight line, and in the turning conveying platform 4, there are two groups of conveying assemblies 41, namely the first assembly and the second assembly, which are symmetrically and parallelly arranged, with their length direction perpendicular to the straight line where the first conveying platform 1 and the second conveying platform 2 are located, i.e. forming a 90° angle. The roller mechanisms 31 on the lifting frame 32 include three groups, namely group A, group B and group C, which are arranged in the corresponding positions between and outside the conveying belts 412 of the first assembly and the second assembly in the middle of the lifting frame 32 from the top view, i.e. arranged in the space positions of the conveying belts 412 in the order of group A, the belt of the first assembly, group B, the belt of the second assembly, and group C.

[0107] This structure constitutes a turning conveying platform 4 that can realize stable tile turning at different heights and directions, while maintaining the compactness and stability of the system. It can improve the stability of the tiles during the turning conveying process, reduce the risk of tile breakage, improve the conveying efficiency, and ensure the accuracy and efficiency of tile turning through the assistance of the roller mechanisms 31.

[0108] Further, the roller mechanism 31 further comprises a support 313; one end of the support 313 is connected with the roller shaft 311, and the other end is connected with the upper surface of the lifting frame 32.

[0109] As mentioned above, one end of the support 313 is connected with the roller shaft 311, and the other end is connected with the upper surface of the lifting frame 32. This design provides additional support to ensure that the rubber wheels 312 have a certain height in space and the stability of the roller mechanisms 31 during lifting.

[0110] Further, based on the height of the support 313, when the lifting frame 32 is lifted upwards towards the direction of the conveying belt 412 in the lifting space 413 by the lifting cylinder 33, the upper cutting surface of the rubber wheel 312 can be higher than the upper end surface of the conveying belt 412, and the bottom surface of the target ceramic tile delivered by the first conveying platform 1 can contact the rubber wheel 312 and be conveyed onto the second conveying platform 2 by inertia. When the lifting frame 32 is lowered downwards towards the direction of the conveying belt 412 in the lifting space 413 by the lifting cylinder 33, the upper cutting surface of the rubber wheel 312 can be lower than the upper end surface of the conveying belt 412, and the bottom surface of the target ceramic tile delivered by the first conveying platform 1 can contact the upper surface of the conveying belt 412 of the turning conveying platform 4 and be conveyed by the conveying belt 412 of the turning conveying platform 4.

[0111] The support 313 is connected to the roller shaft 311 at one end and to the upper surface of the lifting frame 32 at the other end. The design of the support 313 is to improve the stability of the roller mechanism 31 and ensure that the rubber wheel 312 can stably contact the bottom surface of the ceramic tile during lifting.

[0112] The lifting cylinder 33 controls the lifting frame 32 to move up and down in the lifting space 413. When the lifting frame 32 is lifted, the upper cutting surface of the rubber wheel 312 is higher than the upper end surface of the conveying belt 412, allowing the ceramic tile to be conveyed by inertia to the second conveying platform 2. When the lifting frame 32 is lowered, the upper cutting surface of the rubber wheel 312 is lower than the upper end surface of the conveying belt 412, allowing the ceramic tile to contact the upper surface of the conveying belt 412 of the turning conveying platform 4 and start moving on the turning conveying platform 4.

[0113] In this embodiment, by limiting the height of the support 313 and the movement mode of the lifting frame 32, the transition process of the ceramic tile between different conveying platforms is improved. This design ensures the stability and accuracy of the ceramic tile during turning conveying. This structure allows the ceramic tile to be driven by the lifting frame 32 to adjust the height of the lifting space 413, to smoothly turn on the turning conveying platform 4, to improve the stability of the ceramic tile during turning conveying, to reduce the risk of ceramic tile damage, to improve conveying efficiency, and to ensure the accuracy and efficiency of ceramic tile turning through the assistance of the support 313.

[0114] Embodiment 4

[0115] Reference Figure 10 In this embodiment, based on the above embodiments, a control method for a ceramic tile delivery system 100 is provided, comprising:

[0116] Step S100, obtaining the delivery instruction corresponding to the target ceramic tile on the first conveying platform 1; the delivery instruction includes a direction-changing delivery instruction and a non-direction-changing instruction.

[0117] In this embodiment, the system needs to obtain the delivery instruction of the ceramic tile on the first conveying platform 1 from the control center or the operator. Through the input device or the automatic detection system, the system identifies and records the delivery requirement of each ceramic tile. The system obtains the specific instruction of the ceramic tile delivery, including the direction-changing delivery instruction and the non-direction-changing instruction. By obtaining the instruction, the accuracy and efficiency of the ceramic tile delivery are improved, and the possibility of error delivery is reduced. The delivery instruction can be obtained by operator input or automatic identification system (such as bar code scanner, RFID reader).

[0118] Specifically, it can be realized by programming logic, for example, using sensors to detect the position of the ceramic tile and automatically generating the delivery instruction.

[0119] Step S200, determining whether the delivery instruction is a direction-changing delivery instruction.

[0120] As described above, the system needs to determine whether the obtained delivery instruction requires the ceramic tile to change direction during delivery. By logically judging or algorithmically analyzing the content of the delivery instruction, it is determined whether the ceramic tile needs to be delivered in a direction-changing manner. In this embodiment, the delivery path can be adjusted according to different delivery requirements, improving the flexibility of the system.

[0121] Specifically, the conditional judgment logic can be realized by programming, for example, using if-else statements to determine whether direction-changing is needed.

[0122] Step S300, if not, determining whether the position of the rubber wheel 312 is at a preset position; wherein the preset position is that the height of the upper cutting surface of the rubber wheel 312 is higher than the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4.

[0123] As described above, if the ceramic tile does not need to be delivered in a direction-changing manner, the system needs to check whether the rubber wheel 312 is at the preset position. The system can detect the position of the rubber wheel 312 through sensors or encoders. The system determines whether the rubber wheel 312 is at the correct position for straight-line delivery. This ensures the continuity and accuracy of the delivery process and avoids delivery failure due to position errors.

[0124] Specifically, a position sensor or an encoder can be used to detect the position of the rubber wheel 312.

[0125] For example, the preset position is that the lifting frame 32 is at the correct position, so that the height of the upper cutting surface of the rubber wheel 312 is higher than the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4, achieving the state of ceramic tile transportation and delivery.

[0126] For example, the straight line formed by the upper cutting surface of the plurality of rubber wheels 312 can intersect the first conveying platform and the second conveying platform, and the target tile can smoothly contact the rubber wheels 312 after being separated from the first conveying platform and continue to move forward by inertia to smoothly reach the second conveying platform.

[0127] In step S400, if the position of the rubber wheels 312 is in the preset position, it is determined that the lifting device 3 reaches the conveying state.

[0128] If the position of the rubber wheels 312 is correct, the system determines that the lifting device 3 is ready for delivery. The system confirms the state of the lifting device 3 and prepares for the delivery operation. The lifting device 3 is ready to start delivering tiles. The reliability of delivery is improved, and the smooth progress of the delivery process is ensured. The state of the lifting device 3 can be displayed to the operator through the status indicator light or the display screen.

[0129] In step S500, if the position of the rubber wheels 312 is not in the preset position, it is determined that the lifting device 3 does not reach the conveying state, and the lifting cylinder 33 in the lifting device 3 is controlled to act upward to make the lifting frame 32 rise in the lifting space 413 toward the upper end of the conveying belt 412 of the conveying platform 4, so that the height of the upper cutting surface of the rubber wheels 312 is higher than the upper end surface of the conveying belt 412 of the conveying platform 4, and reaches the preset position.

[0130] If the position of the rubber wheels 312 is incorrect, the system determines that the lifting device 3 is not ready for delivery. The system can send a control signal to adjust the position of the lifting device 3. The lifting device 3 is adjusted to the correct position and is ready for delivery. The accuracy and efficiency of the delivery process can be ensured by automatic adjustment, and the position of the lifting frame 32 is adjusted by controlling the action of the lifting cylinder 33 through PLC (Programmable Logic Controller).

[0131] During the adjustment, the system controls the lifting cylinder 33 to lift the lifting frame 32 so that the height of the rubber wheels 312 is higher than the conveying belt 412 of the conveying platform 4. The system sends a control signal to the lifting cylinder 33 to move the lifting frame 32 upward. The lifting frame 32 rises, and the rubber wheels 312 reach the correct height, ready to deliver tiles, thereby ensuring that the tiles can be smoothly delivered from the first conveying platform 1 to the second conveying platform 2.

[0132] The precise positioning of the lifting frame 32 can be achieved by precisely controlling the stroke of the lifting cylinder 33, so that in this step, the bottom surface of the target tile delivered by the first conveying platform 1 can contact the rubber wheels 312 and be conveyed to the second conveying platform 2 by inertia.

[0133] After the adjustment, the height of the rubber wheel 312 is ensured to be higher than the conveying belt 412, reaching the preset position, so that the tile can smoothly contact the rubber wheel 312. The system achieves this condition by adjusting the height of the lifting frame 32. The bottom surface of the tile can contact the rubber wheel 312 and be conveyed to the second conveying platform 2 by inertia through the rubber wheel 312.

[0134] After the tile contacts the rubber wheel 312, it is conveyed to the second conveying platform 2 by inertia. The system controls the speed and position of the rubber wheel 312 to ensure that the tile can smoothly reach the second conveying platform 2. The tile is conveyed to the second conveying platform 2 in a straight line, thereby simplifying the delivery process and reducing complexity and possible errors in the delivery process.

[0135] The straight-line conveying of the tile can be achieved by precisely controlling the speed and position of the rubber wheel 312.

[0136] Further, after determining whether the delivery instruction is a direction-changing delivery instruction, the system further comprises:

[0137] Step S600: If yes, determine whether the position of the rubber wheel 312 is at the preset position.

[0138] If the delivery instruction requires direction-changing delivery, the system needs to check whether the rubber wheel 312 is at the preset position required for direction-changing delivery. The current position of the rubber wheel 312 is detected by a sensor and compared with the preset position. It is determined whether the rubber wheel 312 is already at the position required for direction-changing delivery. Thus, the accuracy and timeliness of direction-changing delivery are ensured, and delivery failure due to position error is avoided.

[0139] The position of the rubber wheel 312 can be detected by a position sensor or an encoder.

[0140] Step S700: If the position of the rubber wheel 312 is at the preset position, determine that the lifting device 3 reaches the conveying state.

[0141] If the rubber wheel 312 is already at the preset position, the system determines that the lifting device 3 is ready for direction-changing delivery. The system confirms the state of the lifting device 3 and prepares for direction-changing delivery operation. The lifting device 3 is ready and can start direction-changing delivery of the tile.

[0142] Step S800, when the target tile is transported by the first conveying platform 1 above the lifting frame 32 and contacts the rubber wheel 312, the system controls the lifting cylinder 33 to act downward to make the lifting frame 32 descend in the lifting space 413 to the height of the upper cutting surface of the rubber wheel 312 below the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4, the bottom surface of the target tile contacts the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4 via the rubber wheel 312, the speed of the target tile in the straight conveying direction is reduced to 0 m / s, and the target tile is conveyed in a non-straight direction by the conveying belt 412 of the direction-changing conveying platform 4.

[0143] When the tile reaches above the lifting frame 32 and contacts the rubber wheel 312, the system controls the lifting cylinder 33 to lower the lifting frame 32. The system sends a control signal to the lifting cylinder 33 to move the lifting frame 32 downward. The lifting frame 32 descends, and the height of the upper cutting surface of the rubber wheel 312 is below the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4. Thus, it is ensured that the tile can be smoothly transferred from the rubber wheel 312 to the direction-changing conveying platform 4.

[0144] The bottom surface of the tile contacts the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4 via the rubber wheel 312. The system controls the descending speed and position of the lifting frame 32 to ensure smooth transfer of the tile. The tile is successfully transferred to the direction-changing conveying platform 4 and starts to be conveyed in a non-straight direction.

[0145] The system needs to reduce the speed of the tile in the straight conveying direction to zero to ensure safe transfer to the direction-changing conveying platform 4. The system controls the speed of the lifting cylinder 33 and the conveying platform to make the tile have a speed of zero when transferring. The tile is completely stopped before changing direction, avoiding the occurrence of deviation from the conveying belt 412, falling, damage or delivery failure due to speed mismatch, thereby ensuring the safety and accuracy of the tile during the transfer process.

[0146] Specifically, the precise stopping of the tile can be achieved by controlling the speed of the conveying platform and the lifting cylinder 33.

[0147] Finally, the tile starts to be conveyed in a non-straight direction on the direction-changing conveying platform 4. The system controls the conveying belt 412 of the direction-changing conveying platform 4 to start the non-straight conveying operation. The tile is conveyed to the destination according to the predetermined non-straight path.

[0148] Step S900, if the position of the rubber wheel 312 is not at the preset position, it is determined that the lifting device 3 has not reached the conveying state, and the lifting cylinder 33 in the lifting device 3 is controlled to act upward to make the lifting frame 32 in the lifting space 413 rise towards the upper end of the conveying belt 412, so that the height of the upper cutting surface of the rubber wheel 312 is higher than the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4, the preset position is reached, and the step S600 of judging whether the position of the rubber wheel 312 is at the preset position is returned to be executed.

[0149] Embodiment 5

[0150] In this embodiment, based on the above embodiments, a control method of a ceramic tile conveying system 100 is provided. The step S800, when the target ceramic tile is conveyed by the first conveying platform 1 to above the lifting frame 32 and contacts the rubber wheel 312, the lifting cylinder 33 is controlled to act downward to make the lifting frame 32 in the lifting space 413 descend to the height of the upper cutting surface of the rubber wheel 312 is lower than the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4, the bottom surface of the target ceramic tile contacts the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4 through the rubber wheel 312, the speed of the target ceramic tile in the straight line conveying direction is reduced to 0 m / s, and the target ceramic tile is conveyed in a non-straight line direction by the conveying belt 412 of the direction-changing conveying platform 4, comprising:

[0151] Step S810, obtaining the initial speed of the first conveying platform 1 conveying the target ceramic tile in the straight line direction, and calculating the trigger position of the lifting frame 32 starting the lowering action corresponding to the target ceramic tile based on the initial speed.

[0152] The system needs to measure or calculate the initial speed of the ceramic tile on the first conveying platform 1. The moving speed of the ceramic tile can be monitored in real time by a speed sensor or an encoder. The system obtains the initial speed data of the ceramic tile on the first conveying platform 1, which can accurately control the conveying speed of the ceramic tile and provide necessary parameters for subsequent direction-changing conveying.

[0153] According to the initial speed of the ceramic tile, the specific position at which the lifting frame 32 needs to start the lowering action is calculated. The trigger position can be calculated by a control algorithm combined with the speed and conveying distance of the ceramic tile. The accurate position at which the lifting frame 32 starts to lower is determined to ensure that the ceramic tile can be smoothly transferred to the direction-changing conveying platform 4. Thus, the accuracy and reliability of the ceramic tile transfer are improved, and the error in the transfer process is reduced.

[0154] The preset segmented control function model can be realized by programming to calculate the trigger position according to the speed and distance.

[0155] Step S820, obtain the current position of the target tile, based on the trigger position, control the state of the lifting frame 32 through the preset segmented control function model, so that when the target tile contacts the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4, the initial speed of the target tile in the straight line direction conveying is reduced to 0 m / s.

[0156] The system needs to monitor the current position of the tile in real time during conveying. The position of the tile can be tracked in real time by a position sensor or encoder. The actions of the conveying and lifting frame 32 can be adjusted in real time to ensure that the tile is accurately transferred to the direction-changing conveying platform 4.

[0157] According to the information of the tile reaching the trigger position, the system adjusts the state of the lifting frame 32 through the preset control model. Specifically, the system can adjust the action of the lifting cylinder 33 according to the preset control logic, so that the lifting frame 32 is lowered, and the lifting frame 32 starts to lower when the tile reaches the predetermined position, preparing for the direction-changing conveying of the tile. Precise timing control is achieved, ensuring that the tile is transferred to the direction-changing conveying platform 4 at the correct time and position. The preset segmented control function model can be realized through PLC (Programmable Logic Controller).

[0158] When the tile contacts the upper end surface of the conveying belt 412 of the direction-changing conveying platform 4, its speed is reduced to zero. By precisely controlling the lowering action of the lifting frame 32 and the speed of the conveying platform, the tile is smoothly stopped. The tile is completely stopped before direction-changing conveying, avoiding deviation, disengagement from the conveying belt, falling, damage or delivery failure due to speed mismatch. The safety and accuracy of the tile during the transfer process are ensured. Precise stopping of the tile can be achieved by controlling the speed of the conveying platform and the lifting cylinder 33.

[0159] Thus, through the above steps, the tile starts to be conveyed in a non-straight line direction on the direction-changing conveying platform 4. The system controls the conveying belt 412 of the direction-changing conveying platform 4 to start the non-straight line conveying operation.

[0160] Further, in step S810, the trigger position for the lifting frame 32 to start lowering action corresponding to the target tile calculated based on the initial speed includes:

[0161] Step S811, calculate the total deceleration of the target tile; the calculation expression [formula 1] of the total deceleration is: a=(μ1+μ2)×g; where a represents the total deceleration; μ1 represents the friction coefficient between the target tile and the rubber wheel 312; μ2 represents the friction coefficient between the target tile and the conveying belt 412; g represents the acceleration of gravity.

[0162] As mentioned above, in this step, the total deceleration of the ceramic tile during the change direction conveying process needs to be calculated. The total deceleration is calculated using formula 1, where μ1 is the friction coefficient between the ceramic tile and the rubber wheel 312, μ2 is the friction coefficient between the ceramic tile and the conveying belt 412, and g is the acceleration of gravity. Thus, the total deceleration a of the ceramic tile during the change direction conveying process is obtained.

[0163] The parameters required for the deceleration of the ceramic tile can be accurately calculated by formula 1, providing a basis for subsequent deceleration distance calculation. The friction coefficients can be determined by experiment, and the standard value of the acceleration of gravity is used for calculation.

[0164] As mentioned above, the friction coefficient μ1 between the target ceramic tile and the rubber wheel 312 and the friction coefficient μ2 between the target ceramic tile and the conveying belt 412 can be pre-measured constant values; g represents the acceleration of gravity, which can be approximately 9.8 m / s 2 .

[0165] Step S812, the deceleration distance of the target ceramic tile is calculated according to the total deceleration; the calculation expression [formula 2] of the deceleration distance is: where d represents the deceleration distance of the target ceramic tile in the straight line direction, so that the initial speed is reduced to 0; V h represents the initial speed of the target ceramic tile.

[0166] As mentioned above, in this step, the deceleration distance of the ceramic tile from the initial speed to 0 needs to be calculated. The deceleration distance is calculated using formula 2, where V h is the initial speed of the ceramic tile, and d is the distance required for the ceramic tile to decelerate to stop. It ensures that the ceramic tile can safely and smoothly decelerate to stop before reaching the change direction conveying platform 4, avoiding impact and damage.

[0167] Step S813, based on the deceleration distance, the trigger position of the lifting frame 32 starting the lowering action is calculated; the calculation expression [formula 3] of the trigger position is: x start =D-d; where x start represents the trigger position; D represents the total distance of the target ceramic tile reaching the conveying belt 412 of the change direction conveying platform 4.

[0168] In this step, the system needs to determine the specific position of the lifting frame 32 starting the lowering action to ensure that the ceramic tile can be smoothly decelerated and transferred to the change direction conveying platform 4. The trigger position is calculated using formula 3, where D is the total distance of the ceramic tile reaching the change direction conveying platform 4. The trigger position x start of the lifting frame 32 starting the lowering action is obtained. Precise timing control is achieved, ensuring that the ceramic tile is transferred to the change direction conveying platform 4 at the correct time and position.

[0169] Further, in step S820, the expression of the preset piecewise control function model is [formula 4]: Wherein, H(x) represents the height of the lifting frame 32 at position x; H lifted represents the height of the lifting frame 32 when it is raised; H lowered represents the height of the lifting frame 32 after it is lowered.

[0170] In this embodiment, a piecewise control function model H(x) is defined to control the height of the lifting frame 32, which adjusts the height of the lifting frame 32 according to the current position x of the tile. The piecewise function H(x) contains three parts, corresponding to different position intervals of the tile.

[0171] The height of the lifting frame 32 is dynamically adjusted according to the position of the tile. The purpose of precisely controlling the height of the lifting frame 32 is achieved, ensuring that the tile can be smoothly transferred to the direction-changing conveying platform 4. This piecewise function can be realized by programming, using conditional statements to adjust the height of the lifting frame 32 according to different position intervals.

[0172] In step S820, the state of the lifting frame 32 is controlled by the preset piecewise control function model, which includes:

[0173] Step S821, when the current position x of the target tile reaches x start , the lifting frame 32 starts to descend.

[0174] The system monitors the position of the tile, and when the tile reaches the trigger position x start , the lifting frame 32 starts to descend.

[0175] The system monitors the position of the tile through the position sensor, and sends a signal to the lifting cylinder 33 when it reaches x start , so that it starts to descend. Thus, the lifting frame 32 starts to descend when the tile reaches the correct position. This ensures that the tile starts to transfer to the direction-changing conveying platform 4 at the correct time, improving the response speed and accuracy of the system.

[0176] The position monitoring and lifting frame 32 control can be realized by PLC (Programmable Logic Controller).

[0177] Step S822, during the process of controlling the target tile from x start to D, the height of the lifting frame 32 is linearly lowered, so that when x=d, the lifting frame 32 is completely lowered, and when the target tile contacts the upper surface of the conveying belt 412, the speed in the straight conveying direction can be reduced to 0 m / s.

[0178] In the above steps, when the tile is from x startDuring the process of moving to D, the system needs to linearly reduce the height of the lifting frame 32. The system linearly adjusts the height of the lifting frame 32 according to the position of the tile and the preset piecewise control function model.

[0179] The height of the lifting frame 32 is linearly reduced as the tile position moves. Linearly reducing the lifting frame 32 can ensure that the tile smoothly contacts the conveying belt 412, reducing the risk of impact and damage.

[0180] The linear adjustment of the height of the lifting frame 32 can be achieved by a proportional-integral-derivative (PID) controller or other control algorithm.

[0181] When the tile reaches the deceleration distance d, the lifting frame 32 needs to be fully lowered, and the speed of the tile needs to be reduced to zero. The system controls the lifting cylinder 33 so that the lifting frame 32 is fully lowered when the tile reaches d, and the speed of the tile is reduced to zero by friction. At this time, the tile is smoothly transferred to the turning conveying platform 4 with zero speed, avoiding impact on the conveying belt 412. Through the method provided in this step, the safety of tile transfer and the stability of the system are improved, and the maintenance cost is reduced.

[0188] (3) Determine control trigger point: Calculate the trigger position x start of the control action, which is D-d. When the position of the target tile reaches D-d during movement, the control action (i.e., lowering the lifting frame 32) is started to ensure that the horizontal speed of the target tile is just zero when it reaches and contacts the conveying belt 412 of the direction-changing conveying platform 4.

[0189] (4) Implement lifting frame 32 control:

[0190] When the current position x start of the target tile reaches x start , start lowering the lifting frame 32; during the process of the target tile from x start to D, linearly lower the height of the lifting frame 32 to ensure that the lifting frame 32 is completely lowered when x=D.

[0191] (5) Ensure smooth transition: Through the above control function model, ensure that the original initial speed V h of the tile is just zero when it contacts the conveying belt 412 of the direction-changing conveying platform 4, completing smooth direction-changing conveying (such as right-angle direction conveying).

[0192] 3. Model verification:

[0193] In order to verify the accuracy of the model and ensure that the horizontal speed can be reduced to 0 when x=D, the following derivation is carried out:

[0194] (1) Deceleration time t:

[0195] (2) Displacement verification during deceleration:

[0196] When the target tile starts to decelerate from x h start=D-d, and reaches x=D: V h (D)=V h -a×t=0;

[0197] The above derivation verifies the correctness of the model, i.e., the horizontal speed of the target tile can be reduced to zero within a distance d.

[0198] 4. Summary:

[0199] The above function model realizes smooth direction-changing conveying of the target tile through the following steps:

[0200] (1) Calculate total deceleration and deceleration distance: Based on the friction coefficient and gravitational acceleration, calculate the total deceleration a of the tile and the required deceleration distance d.

[0201] (2) Determine the control trigger point: Start lowering the lifting frame 32 at a distance d before the target tile reaches the conveyor belt 412.

[0202] (3) Control the height of the lifting frame 32: Use a piecewise function model to linearly lower the height of the lifting frame 32, ensuring that the initial speed is reduced to zero when the target tile reaches the conveyor belt 412.

[0203] (4) Achieve smooth transition: By precisely controlling the height change of the lifting frame 32, achieve smooth deceleration of the initial speed of the target tile in the straight conveying direction, avoid deviation, falling, and separation from the belt, and ensure the stability of the tile turning conveying.
