Description

Technical Field

[0001] The utility model relates to the technical field of object turnover, in particular to a transfer device for laminated plates during transfer. Background Art

[0002] In the fields of architectural decoration, construction and manufacturing, the product characteristics impose extremely strict technological requirements on the flatness of plates. After being processed by a shot blasting machine, the plates often undergo random deformation due to stress release or processing deformation, which significantly reduces the surface flatness of the plates and thus cannot meet the requirements of subsequent processing or installation. Therefore, it is necessary to perform straightening treatment on the plates through a leveling process to restore their flatness and ensure product quality. Currently, a leveling machine is the mainstream equipment for plate leveling. Its working principle is to apply pressure to the plates to gradually eliminate the deformation of the plates, thereby achieving the purpose of leveling. However, the leveling effect of a roller leveling machine highly depends on the input direction of the plates. Only when the convex surface of the plate faces upward can the best straightening effect be achieved. However, in the actual production process, when the plates after the shot blasting process are output by a conveyor belt, their deformation direction is that the convex surface faces downward, which poses a great challenge to the subsequent leveling process. In order to ensure the leveling effect, it is necessary to add a turning adjustment link between the shot blasting and leveling processes to achieve the optimal leveling effect.

[0003] There are mainly two existing methods for turning and direction adjustment. One is to use a 6-axis industrial robot to grab and turn the plates, but this method requires an additional transfer table, resulting in high equipment costs; moreover, the actions of the robot are complex and the cycle time is long, making it difficult to match the production rhythm of a high-efficiency production line and unable to meet the production requirements of large-scale and high-efficiency production. The other is manual turning. Although manual operation has a certain degree of flexibility, the labor intensity is high, and the operators are prone to fatigue, resulting in a decrease in work efficiency. At the same time, manual turning also has safety hazards. In the process of large-scale production, it is difficult to ensure the stability and safety of production and cannot meet the requirements of large-scale production.

[0004] Therefore, in view of this, the inventor proposes a transfer device for laminated plates during transfer to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a transfer device for laminated plates during transfer to solve the problem that the existing plates are not convenient for turning operations, resulting in the inconvenience of automatic connection between the shot blasting process and the leveling process.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] A transfer device for laminated plates, which is used to be installed between a shot blasting machine and a leveling machine, includes two conveying mechanisms and a flipping mechanism. The flipping mechanism is arranged between the two conveying mechanisms, and both ends of the flipping mechanism are respectively connected to the two conveying mechanisms;

[0008] The flipping mechanism includes two support platforms, two connecting columns, a first driving member and a flipping assembly. Each connecting column is rotatably installed on the corresponding support platform. Both ends of the flipping assembly are respectively connected to the two connecting columns. The first driving member is arranged on one of the support platforms and is used to drive the connecting column to rotate;

[0009] A plurality of clamping mechanisms are arranged on the flipping mechanism, and the clamping mechanisms are used to limit the position of the plate.

[0010] According to the above technical solution, first, the plate processed by the shot blasting machine is conveyed to the flipping mechanism. The flipping mechanism is located between the two conveying mechanisms between the shot blasting machine and the leveling machine and is connected to the two conveying mechanisms. When the plate enters the flipping mechanism, the first driving member is started to drive the connecting column to rotate, thereby driving the flipping assembly to start working. Both ends of the flipping assembly are respectively connected to the two connecting columns. As the connecting column rotates, the flipping assembly flips the plate 180 degrees. During the flipping process, a plurality of clamping mechanisms arranged on the flipping mechanism limit the position of the plate to ensure that the plate is stable during the flipping process and will not slide or fall. After the flipping is completed, the plate is conveyed to the conveying mechanism on the other side and then conveyed to the leveling machine for leveling treatment. The entire flipping process realizes the automatic flipping of the plate between the shot blasting machine and the leveling machine, improves the production efficiency, reduces the labor intensity, and ensures the safety and stability of production.

[0011] Further, the connecting column includes a connecting block and a rotating shaft. The connecting block is detachably connected to the flipping mechanism. The connecting block is coaxially connected to the rotating shaft, and the rotating shaft is rotatably installed on the support platform.

[0012] Further, the first driving member includes a first motor fixed on one of the support platforms. The first motor is connected with a worm. A worm gear is coaxially and fixedly connected to one of the rotating shafts, and the worm gear meshes with the worm.

[0013] Further, the flipping assembly includes a flipping frame, two second driving members and two flipping units symmetrically arranged on the flipping frame. A passage for the plate to pass through is arranged between the two flipping units. When the plate is located in the passage between the two flipping units, the clamping mechanism can limit the position of the plate.

[0014] Further, the flipping unit includes a first bracket and a second bracket which are symmetrically arranged. The second bracket is perpendicular to and fixed to the first bracket. Two first pulleys are rotatably connected to both ends of the second bracket, and a second pulley is rotatably connected to the top of the second bracket. A belt is tensioned between the first pulley and the second pulley.

[0015] Further, the second driving member includes a second motor fixedly arranged on one of the second brackets, and the output shaft of the second motor is coaxially connected to one of the second pulleys.

[0016] A synchronizing shaft is arranged between the second pulleys.

[0017] Further, the clamping mechanism is a clamping member. The number of the clamping members is multiple, and each clamping member is correspondingly installed on the first bracket. The clamping member has a first state and a second state, and the first state and the second state can be mutually converted. The second state is used for clamping and limiting the board in the channel.

[0018] Further, the clamping member includes a claw, a pin shaft and a cylinder. The pin shaft penetrates through the middle position of the claw to rotatably install the claw on the first bracket. The cylinder is movably installed on the first bracket, and the piston end of the cylinder is hinged to one end of the claw.

[0019] Further, the clamping mechanism is a suction cup. The number of the suction cups is multiple, and each suction cup is communicated with a pneumatic pump. The suction cups are installed on the first bracket and can adsorb or release the board.

[0020] Further, the conveying mechanism includes a base and two side plates fixedly arranged above the base. A plurality of rotating rollers are arranged between the two side plates. Two driven sprockets are arranged at one end of the rotating roller, and a first chain is arranged between two adjacent driven sprockets.

[0021] A third motor is arranged on the base, and a driving sprocket is connected to the output shaft of the third motor. A second chain is arranged between the driving sprocket and one of the driven sprockets.

[0022] The beneficial effects of the present utility model:

[0023] The plate of the present utility model is conveyed to the flipping mechanism after being processed by a shot blasting machine. The flipping mechanism is located between two conveying mechanisms between the shot blasting machine and the leveling machine and is connected to the two conveying mechanisms. When the plate enters the flipping mechanism, the clamping mechanism positions the plate to ensure its stability during flipping and prevent it from sliding or falling. Then, the first driving member is activated to drive the connecting column to rotate, thereby driving the flipping assembly to start working. The two ends of the flipping assembly are respectively connected to the two connecting columns. As the connecting column rotates, the flipping assembly flips the plate by 180 degrees. After flipping is completed, the plate is conveyed to the conveying mechanism on the other side and then transferred to the leveling machine for leveling treatment. The entire flipping process realizes the automatic flipping of the plate between the shot blasting machine and the leveling machine, improving production efficiency, reducing labor intensity, and ensuring the safety and stability of production.

Detailed implementation manners

[0034] The following will describe the implementation manners of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention, rather than for limiting the protection scope of the present invention.

[0035] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in its actual implementation can be arbitrarily changed, and the layout type of its components may also be more complex.

[0036] This embodiment proposes a laminated board transfer and conveying device, which is used to be installed between the shot blasting machine 5 and the leveling machine 6, as Figures 1 to 8 shown, including two conveying mechanisms 1 and a flipping mechanism 2. The flipping mechanism 2 is arranged between the two conveying mechanisms 1, and the left and right ends of the flipping mechanism 2 are respectively connected to the two conveying mechanisms 1.

[0037] As Figure 3 , Figure 4 and Figure 5As shown in the figure, the flipping mechanism 2 includes two support platforms 21, two connecting columns 22, a first driving member 23 and a flipping assembly 24. The connecting columns 22 are rotatably installed on the corresponding support platforms 21. Both ends of the flipping assembly 24 are respectively connected to the two connecting columns 22. The first driving member 23 is arranged on one of the support platforms 21 and is used to drive the connecting column 22 to rotate. A plurality of clamping mechanisms are arranged on the flipping mechanism 2, and the clamping mechanisms are used to limit the position of the plate 4.

[0038] As a preferred embodiment, as Figure 4 shown, the connecting column 22 includes a connecting block 222 and a rotating shaft 221. The connecting block 222 is connected to the flipping mechanism 2 in a form of bolt connection. The connecting block 222 is coaxially connected to the rotating shaft 221, and the rotating shaft 221 is rotatably installed on the support platform 21.

[0039] As a preferred embodiment, as Figure 3 and Figure 4 shown, the first driving member 23 includes a first motor 231 fixed on the right support platform 21. The first motor 231 is connected with a worm 232. A worm gear 233 is coaxially and fixedly connected to one of the rotating shafts 221 (the right rotating shaft 221). The worm gear 233 meshes with the worm 232. When the first motor 231 is started, it drives the worm 232 to start rotating. The worm 232 drives the worm gear 233 to rotate, thereby driving the rotating shaft 221 to rotate. Since the connecting block 222 is coaxially connected to the rotating shaft 221, the rotation of the rotating shaft 221 will drive the connecting block 222 to rotate, and further drive the flipping assembly 24 to rotate, realizing the flipping of the plate 4.

[0040] As a preferred embodiment, as Figure 4 and Figure 5 shown, the flipping assembly 24 includes a flipping frame 241, two second driving members 242 and two flipping units 243 symmetrically arranged on the flipping frame 241. A channel 244 for the plate 4 to pass through is arranged between the two flipping units 243. The channel 244 is flush with the upper surface of the conveying mechanism 1. When the plate 4 is conveyed to the channel 244 between the two flipping units 243, the clamping mechanism can limit and fix the position of the plate 4.

[0041] As a preferred embodiment, as Figure 7 and Figure 8 shown, the conveying mechanism 1 includes a base 11 and two side plates 12 fixedly arranged above the base 11. A plurality of rotating rollers 13 are arranged between the two side plates 12. Two driven sprockets 131 are arranged at one end of the rotating roller 13. A first chain 132 is arranged between two adjacent driven sprockets 131; A third motor 14 is arranged on the base 11. A driving sprocket 141 is connected to the output shaft of the third motor 14. A second chain (not shown) is arranged between the driving sprocket 141 and one of the driven sprockets 131.

[0042] In this embodiment, the conveying mechanism 1 is an important part of the sheet turning device, mainly responsible for the conveying task of the sheet 4. The rotating roller 13 can support the sheet 4 and drive the sheet 4 to move. A driving sprocket 141 is connected to the output shaft of the third motor 14, and the driving sprocket 141 is connected to one of the driven sprockets 131 through a second chain. When the third motor 14 is started, the third motor 14 drives the driving sprocket 141 to rotate, and the driving sprocket 141 drives the driven sprocket 131 to rotate through the second chain. The rotation of the driven sprocket 131 drives other rotating rollers 13 to rotate together through the first chain 132. In this way, the rotating rollers 13 on the entire conveying mechanism 1 can work together, and the friction generated by the rotation drives the sheet 4 to move smoothly on the conveying mechanism 1, thereby realizing the conveying operation of the sheet 4.

[0043] As Figure 6 shown, the flipping unit 243 includes symmetrically arranged first brackets 2431 and second brackets 2432. The second bracket 2432 is perpendicular to the first bracket 2431 and fixed to the first bracket 2431. The two ends of the second bracket 2432 are rotatably connected with first pulleys 2433, and the top of the second bracket 2432 is rotatably connected with a second pulley 2434. A belt 2435 is tensioned between the two first pulleys 2433 and the second pulley 2434. The second driving member 242 includes a second motor 2421 fixedly arranged on one of the second brackets 2432. The output shaft of the second motor 2421 is coaxially connected with one of the second pulleys 2434, and a synchronizing shaft 2422 is arranged between the second pulleys 2434.

[0044] In this embodiment, when the second motor 2421 is started, it drives the second pulley 2434 to rotate. At the same time, a synchronizing shaft 2422 is arranged between the two second pulleys 2434, and the synchronizing shaft 2422 synchronizes the rotational movements of the two second pulleys 2434 to ensure that the two second pulleys 2434 rotate at the same speed and in the same direction. In this way, when the sheet 4 enters the channel 244 between the two flipping units 243, the belt 2435 contacts the sheet 4, and the belt 2435 can drive the sheet 4 to move between the channels 244. When the sheet 4 moves to a certain position (such as when the sheet 4 moves to the middle position of the first bracket 2431), the clamping mechanism is started to limit the sheet 4 to ensure that the sheet 4 does not slide or fall during the flipping process.

[0045] As a preferred embodiment, as Figure 6As shown, the clamping mechanism is the engaging part 25. The number of engaging parts 25 is four or eight, which are respectively installed on the first bracket 2431. In this embodiment, the number of engaging parts 25 is four. When the plate 4 enters the channel 244, the engaging parts 25 are symmetrically arranged in pairs on the left and right sides of the plate 4 respectively; the engaging part 25 has a first state and a second state, and the first state and the second state can be converted into each other. The second state is used to clamp and limit the plate 4 in the channel 244. The engaging part 25 includes a claw 251, a pin shaft 252 and a cylinder 253. The pin shaft 252 passes through the middle position of the claw 251 to rotatably install the claw 251 on the first bracket 2431. The end of the cylinder 253 is hinged and installed on the first bracket 2431, and the piston end of the cylinder 253 is hinged to one end of the claw 251.

[0046] In this embodiment, when it is necessary to clamp the plate 4, the cylinder 253 is started, the piston end extends, and pushes the claw 251 to rotate around the pin shaft 252, so that the other end of the claw 251 approaches the plate 4 until it contacts the plate 4 and generates a clamping force (at this time, it is in the second state), restricting the plate 4 in the channel 244 to prevent it from sliding or falling during the flipping process. When it is necessary to release the plate 4, the piston end of the cylinder 253 retracts, pulling the claw 251 to rotate reversely around the pin shaft 252, so that the other end of the claw 251 moves away from the plate 4, releasing the clamping state (at this time, it is in the first state, that is Figure 6 the state of the engaging part 25 in). Driven by the belt 2435, the plate 4 can move in the channel 244, and the plate 4 is conveyed to the conveying mechanism 1 on the other side. During the whole process, the engaging part 25 and the cylinder 253 work together to ensure the stability and reliability of the plate 4 during the flipping process.

[0047] In a possible implementation manner, the clamping mechanism is a suction cup. The number of suction cups is multiple, and each suction cup is connected to a pneumatic pump. The suction cups are installed on the first bracket 2431 for adsorbing or releasing the plate 4. In this embodiment, the clamping mechanism adopts the suction cup design to achieve stable control of the plate 4. Multiple suction cups are installed on the first bracket 2431 of the flipping unit 243, and each suction cup is connected to the pneumatic pump. When it is necessary to fix the plate 4, the pneumatic pump starts to work, providing negative pressure for the suction cups, so that the suction cups tightly adsorb on the surface of the plate 4, thereby firmly restricting the plate 4 in the channel 244 to ensure that it will not slide or fall during the flipping process. When it is necessary to release the plate 4, the pneumatic pump stops working, the negative pressure in the suction cups disappears, and the adsorption force between the suction cups and the plate 4 disappears. This suction cup type clamping mechanism realizes flexible adsorption and release of the plate 4 through the control of the pneumatic pump, providing a stable and reliable guarantee for the flipping process of the plate 4.

[0048] In this embodiment, the sheet 4 processed by the shot blasting machine 5 is conveyed to the flipping mechanism 2. The flipping mechanism 2 is located between two conveying mechanisms 1 between the shot blasting machine 5 and the leveling machine 6 and is connected to the two conveying mechanisms 1. When the sheet 4 enters the flipping mechanism 2, the clamping mechanism positions the sheet 4 to ensure that the sheet 4 is stable during flipping and will not slide or fall. Then, the first driving member 23 is activated to drive the connecting column 22 to rotate, thereby driving the flipping assembly 24 to start working. Both ends of the flipping assembly 24 are respectively connected to the two connecting columns 22. As the connecting column 22 rotates, the flipping assembly 24 flips the sheet 4 by 180 degrees. After flipping is completed, the sheet 4 is conveyed to the conveying mechanism 1 on the other side and then transferred to the leveling machine for leveling treatment. The entire flipping process realizes the automatic flipping of the sheet 4 between the shot blasting machine 5 and the leveling machine 6, improves production efficiency, reduces labor intensity, and ensures the safety and stability of production.

Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
