Description

Technical Field

[0001] This invention relates to the field of ceramic tile packaging equipment technology, and in particular to a high-speed packaging machine with synchronous paper feeding. Background Technology

[0002] A tile packaging machine is an automatic tile packaging equipment that replaces manual operation. Automated production can greatly improve the processing efficiency of tile packaging. Existing tile packaging machines generally include a centering mechanism, a brick feeding mechanism, a paper feeding mechanism, a conveying mechanism, a corner wrapping mechanism, and a paper folding mechanism, all mounted on the frame. Above the centering mechanism and the paper feeding mechanism, there is a brick conveying mechanism. On one side of the paper feeding mechanism, there is a paper storage mechanism. The centering mechanism first centers the conveyed brick package, and the paper feeding mechanism conveys the paper from the paper storage mechanism to the conveying mechanism. Then, the brick conveying mechanism picks up the centered brick package and moves it onto the paper on the conveying mechanism. Subsequently, the conveying mechanism drives the brick package and paper to pass through the corner wrapping mechanism and the paper folding mechanism in sequence. The corner wrapping mechanism performs corner wrapping on the brick package, and the paper folding mechanism folds the paper and wraps the brick package, thus replacing manual tile packaging. In traditional tile packaging machines, the cardboard storage mechanism is located on one side of the paper feeding mechanism, while the brick conveying mechanism is situated above both the centering mechanism and the paper feeding mechanism. The brick conveying mechanism needs to lift the brick bundles, pass them over the paper feeding mechanism, and then place them onto the cardboard. This significantly increases the travel distance of the brick conveying mechanism. Furthermore, because the travel distance of the brick bundles is greater than that of the paper feeding mechanism, and the cardboard needs to be stacked with the brick bundles before being sent away together, the cardboard, which arrives faster, has to wait for the brick bundles to arrive, thus affecting subsequent paper feeding. Additionally, the centering mechanism is separate from other mechanisms; the tiles and cardboard are aligned before the corner wrapping process. This not only increases the time for conveying the tiles and cardboard but also increases the overall length and height of the equipment. Therefore, traditional tile packaging machines occupy a large space and have a long overall processing time, resulting in lower tile packaging efficiency. According to the authorized announcement number CN217706478U, an automatic ceramic tile packaging machine includes a paper conveying device and a ceramic tile conveying device located on the same side of the packaging station. The paper conveying device is located below the ceramic tile conveying device, and the conveying direction of the paper conveying device and the ceramic tile conveying device is the same. The paper conveying device is a paper output belt. It also includes a rotatable idler roller installed on the packaging station. The idler roller is located on the side of the packaging station close to the ceramic tile conveying device. It also includes a paper picking device located above the paper conveying device. The paper picking device includes a suction device, a lifting device, and a paper pulling device. The suction device is located on one side of the input end of the paper conveying device. The lifting device is connected to the suction device. The paper pulling device is located between the suction device and the paper conveying device. The paper pulling device includes a paper pulling translation device and a paper clamp. The paper pulling translation device is connected to the paper clamp. The paper pulling synchronous belt drives the slide to move towards the paper, so that the side of the paper enters between the two clamping plates. The clamping claw cylinder is activated and the two clamping plates cooperate to clamp the paper. The paper-pulling synchronous belt drives the slide block to move towards the paper output belt until the paper is located above the input end of the paper output belt. At this time, the gripper cylinder drives the two clamping plates to move and release the paper. The ejector cylinder drives the top plate to move and push the paper away from between the two clamping plates, so that the paper falls onto the input end of the paper output belt. Existing tile packaging machines place the paper conveying device below the tile conveying device and can simultaneously convey tiles and paper. In existing tile packaging machines, paper is conveyed by the back-and-forth movement of the gripper cylinder. During the process of the gripper cylinder gripping the paper from the suction cup and conveying it, the lifting cylinder and the suction cup cooperate to remove the paper again. In this way, the lifting cylinder and the suction cup need to wait for the gripper cylinder to release the paper and reset before conveying the next paper, thus slowing down the paper removal and conveying speed. In addition, the tile conveying and paper conveying work need to be carried out synchronously, which also slows down the tile conveying speed and reduces the overall processing efficiency of the packaging machine. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a high-speed packaging machine with a synchronous paper feeding mechanism positioned below the brick feeding mechanism, allowing the paperboard to be conveyed synchronously with the ceramic tiles. This shortens the time required to convey the ceramic tiles and paperboard, resulting in a more compact and integrated overall structure that reduces the horizontal and vertical space occupied. Furthermore, the conveying rollers and guide clamps of the paper feeder work together to convey the paperboard. After the paperboard removed by the lifting paper picker is conveyed out by the paper feeder, the lifting paper picker can resume its paper picking operation, saving the time spent waiting for the gripper cylinder to reset. This improves the speed of paperboard removal and conveying, thereby shortening the overall processing time and increasing the efficiency of ceramic tile packaging.

[0004] A high-speed packaging machine with synchronized paper feeding includes a centering and feeding mechanism, an upper corner centering mechanism, and a folding mechanism, all sequentially mounted on a frame along the tile conveying direction, as well as a paper feeding mechanism disposed below the centering and feeding mechanism.

[0009] Preferably, the upper corner centering mechanism further includes a corner clamping chamber, a base, a fifth telescopic member, and a sixth telescopic member. The base is located at the discharge port of the corner clamping chamber.

One end of the sixth telescopic member is hinged to the top surface of the base, and the output end of the sixth telescopic member is hinged to the fifth telescopic member.

The frame is provided with a paper guide seat and a guide frame in front of the mounting frame, and the frame is hinged to a folding frame between the two mounting frames along the tile conveying direction. The eighth telescopic member is hinged to the folding frame, and the output end of the eighth telescopic member is hinged to the folding frame.

[0012] Preferably, the centering and feeding mechanism includes a second lifting device, a twelfth telescopic device, a thirteenth telescopic device, and a fourteenth telescopic device.

[0013] The beneficial effects of this invention are as follows: The synchronous paper feeding high-speed packaging machine, through the coordinated operation of the centering brick feeding mechanism, the upper corner centering mechanism, the folding mechanism, and the paper feeding mechanism, positions the paper feeding mechanism below the brick feeding mechanism. This creates a height difference between the paper taking mechanism, the brick feeding mechanism, and the first conveyor, allowing for synchronous conveying of ceramic tiles and cardboard. The tile conveying and cardboard conveying operations do not interfere with each other. Furthermore, the cardboard conveyor on the paper bin rack can hold two stacks of cardboard. After the lifting paper taker finishes conveying one stack, the cardboard conveyor can immediately move the other stack to the position of the lifting paper taker for conveying, eliminating the need to stop the machine and wait for staff to replenish the cardboard, thus improving the cardboard conveying speed. Additionally, the ceramic tiles from the brick feeding mechanism can be directly conveyed along the first conveyor to the second conveyor, eliminating the step of lifting the ceramic tiles, providing straight-line conveying of the tiles, and shortening the brick feeding stroke. By increasing the conveying speed of the tiles, the tiles can reach the cardboard position and be pressed onto the cardboard more quickly, improving the synchronization of the conveying work of the tiles and cardboard. This prevents the long conveying stroke of the tiles from affecting the subsequent conveying of the cardboard. In addition, the conveying rollers and guide clamps of the paper feeder work together to convey the cardboard. After the cardboard picked up by the lifting paper picker is sent out by the paper feeder, the lifting paper picker can pick up paper again, saving the time waiting for the clamp cylinder to reset. This also allows the paper feeder to continuously convey the cardboard, thereby increasing the conveying speed of both the brick package and the cardboard. This not only reduces the conveying time of the tiles and cardboard, but also reduces the overall length and width of the equipment. Therefore, the overall structure of this synchronous paper feeding high-speed packaging machine is more compact and integrated, reducing the overall horizontal and vertical space occupied, thereby shortening the overall processing time and improving the efficiency of tile packaging.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0017] like Figures 1 to 7As shown, a high-speed packaging machine with synchronous paper feeding includes a centering and feeding mechanism 2, an upper corner centering mechanism 3, and a folding mechanism 4, which are sequentially installed on a frame 1 along the tile conveying direction, and a paper feeding mechanism 5 disposed below the centering and feeding mechanism. The frame 1 has a first conveyor 6 and a second conveyor 7 sequentially arranged along the tile conveying direction. The first conveyor 6 conveys the tile centered by the centering and feeding mechanism 2 to the second conveyor 7. The paper feeding mechanism 5 includes a paper bin frame 8, a paper conveyor 9, a lifting paper picker 10, a paper feeder 11, and a paper feeding frame 12. The paper conveyor 9 is disposed within the paper bin frame 8 and conveys paper to the lifting paper picker 10. The lifting paper picker 10, the paper feeder 11, and the paper feeding frame 12 are sequentially arranged on the frame 1 along the paper conveying direction, with the paper feeding frame 12 facing the second conveyor. 7. Inclined upwards, the lifting paper take-up device 10 takes out the paper from the paper conveyor 9 and conveys it to the paper feeder 11. The paper feeder 11 includes a second lifting device 22, a conveying roller 23, a pressure roller 24, and a guide clamp 25. The conveying roller 23 is arranged adjacent to the lifting paper take-up device 10 and the paper feeder 12, and the guide clamp 25 is arranged between two adjacent conveying rollers 23. The output end of the second lifting device 22 is connected to the pressure roller 24 and drives the pressure roller 24 to cooperate with the conveying roller 23 to convey the paper. The paper is conveyed along the paper feeder 11 and the paper feeder 12 to the second conveyor 7 so that the tile conveyed to the second conveyor 7 is pressed on the paper. After the upper corner centering mechanism 3 centers the tile and the paper and wraps the upper corner of the tile, the second conveyor 7 conveys the tile and the paper to the folding mechanism 4.

[0018] The working principle of the synchronous paper feeding high-speed packaging machine described in this invention is achieved through the cooperation of the centering and feeding mechanism 2, the upper corner centering mechanism 3, the folding mechanism 4, and the paper feeding mechanism 5. Figures 1 to 7As shown, the paper feeding mechanism 5 is located below the brick feeding mechanism, creating a height difference between the brick conveying and paperboard conveying operations. This allows the brick conveying and paperboard conveying operations to proceed synchronously. The operator sequentially places two stacks of paperboard into the paperboard conveyor 9 within the paper tray rack 8. The paperboard conveyor 9 moves one stack of paperboard below the lifting paper picker 10, while the other stack is placed on the paperboard conveyor 9 as a backup. There is no need to stop the machine and wait for the operator to replenish the paperboard. The lifting paper picker 10 conveys the paperboard to the paper feeder 11. One side of the paperboard first reaches the position between the conveying roller 23 and the pressure roller 24 in front of the guide clamp 25. Subsequently, the corresponding second lifter 22 drives the pressure roller 24 downwards and... The conveyor roller 23 presses down on the paper, and then the conveyor roller 23 rotates and works with the pressure roller 24 to convey the paper towards the guide clamp 25. Two pressure rollers 24 can be provided on the second lifter 22 to improve the stability of the paper conveying process between the conveyor roller 23 and the pressure roller 24. The paper moves through the guide clamp 25 to between the conveyor roller 23 and the pressure roller 24 behind the guide clamp 25. Similarly, the corresponding second lifter 22 drives the pressure roller 24 downwards and works with the conveyor roller 23 to press down on the paper. The conveyor roller 23 rotates and works with the pressure roller 24 to move the paper towards the paper feeder 12. The second lifter 22 can be a telescopic cylinder. The paper feeder 12 is tilted upwards towards the second conveyor 7 to form an upward tilting conveying mechanism for the paper. The conveyor channel moves the cardboard along the paper feeder 12 to the position of the second conveyor 7, so that the tiles conveyed to the second conveyor 7 are simultaneously pressed onto the cardboard. Finally, the second lifter 22 drives the pressure roller 24 to reset and circulate the cardboard in this way, so that the cardboard is conveyed along the paper feeder 11 and the paper feeder 12 to the second conveyor 7. The tiles are centered by the tile feeding mechanism and then directly conveyed along the first conveyor 6 to the second conveyor 7, so that the tiles and cardboard meet at the second conveyor 7. This eliminates the tile lifting step, conveys the tiles in a straight line and shortens the tile feeding stroke, further improving the tile conveying speed. The tiles can reach the position of the cardboard and press onto the cardboard more quickly, improving the conveying efficiency of both tiles and cardboard. To ensure synchronization and prevent the long travel distance of the ceramic tile from affecting the subsequent paperboard feeding, the ceramic tile and paperboard are then processed at the upper corner centering mechanism 3 for upper corner wrapping and centering. Finally, the ceramic tile and paperboard move along the second conveyor 7 to the folding mechanism 4 for folding, thus completing the ceramic tile packaging process. Compared with traditional ceramic tile packaging machines, this synchronous paper feeding high-speed packaging machine has a more compact and integrated overall structure, reducing the overall horizontal and vertical space occupied. Moreover, the lifting paper picker can pick up paper again after the paperboard is fed out by the paper feeder, saving the time waiting for the gripper cylinder to reset, increasing the paperboard feeding speed, shortening the overall processing time, and improving the ceramic tile packaging efficiency.

[0019] Specifically, the paper tray frame 8 is provided with an opening 13 for replenishing paperboard. Paperboard limiting telescopic devices 14 and baffles 15 are provided on the left and right sides of the paperboard conveying direction along the paperboard. A limiting plate 16 is provided at the output end of the paperboard limiting telescopic device 14. The lifting paper feeder 10 includes a first lifting device 17, a first telescopic device 18, a paper feeder 19, a crossbar 20, and a suction cup 21. The paper feeder 19 is slidably connected to the frame 1 and is connected to the output end of the first lifting device 17. The suction cup 21 is disposed on the crossbar 20. The first telescopic device 18 is disposed on the paper feeder 19, and its output end is connected to the crossbar 20. Figures 1 to 7As shown, the worker first places a stack of cardboard onto the cardboard conveyor 9 through opening 13. The cardboard conveyor 9 then transports the cardboard from opening 13 to below the suction cup 21 of the lifting paper feeder 10. The cardboard conveyor 9 can employ a conventional conveying structure using a conveyor wheel and conveyor belt. A motor driving the conveyor wheel can be installed on the paper tray 8. Next, the worker pre-places a stack of cardboard through opening 13 to replenish the cardboard for later use. When replenishing cardboard to the paper tray 8, the machine does not need to be stopped. The cardboard conveyor 9 can move the spare cardboard to the position of the lifting paper feeder 10, allowing the lifting paper feeder 10 to transport the spare cardboard and increasing the cardboard conveying speed. During cardboard conveying, the cardboard limiting telescopic device 14 and the baffle 15 are connected to the top of the paper tray 8, and the cardboard is limited. The telescopic device 14 and the baffle 15 are spaced apart from the paper conveyor 9 to avoid affecting its normal operation. The paper limiting telescopic device 14 first extends the limiting plate 16 to limit the front side of the paper below the suction cup 21. The first lifting device 17 of the lifting paper take-up device 10 moves the suction cup 21 downward and picks up the paper. After the suction cup 21 picks up the paper, the first lifting device 17 moves the suction cup 21 back to its original position and removes the paper. The limiting plate 16 and the baffle 15 cooperate to limit the paper to prevent the paper from adhering to each other when the suction cup 21 picks up the paper and causing other paper to fall off. The paper limiting telescopic device 14 also moves the limiting plate 16 back to its original position when paper needs to be replenished. Then, the first telescopic device 18 moves the paper picked up by the suction cup 21 towards the paper feeder 11 and the paper is output from the paper bin by the paper feeder 11. The paper tray frame 8 is equipped with a first telescopic device 18 that drives the suction cup 21 to reset and cyclically remove paper. The first lifting device 17 can adopt a lifting structure with a sprocket and chain. A motor that drives the sprocket can be installed on the paper tray frame 8. The paper limit telescopic device 14 and the first telescopic device 18 can be telescopic cylinders. Rollers for conveying paper can be installed on both the conveying roller 23 and the pressure roller 24. A motor that drives the conveying roller 23 can be installed on the frame 1. The guide clamp 25 is located between the two conveying rollers 23. The side of the paper adsorbed by the suction cup 21 first reaches the position between the conveying roller 23 and the pressure roller 24 on the front side of the guide clamp 25. Then, the corresponding second lifting device 22 drives the pressure roller 24 to move downward and cooperate with the conveying roller 23 to press the paper. Immediately afterwards, the suction cup 21 releases the paper, and the conveying roller 23 rotates and cooperates with the pressure roller 24 to press the paper. The pressure roller 24 conveys the cardboard to the guide clamp 25. Two pressure rollers 24 can be installed on the second lifter 22 to improve the stability of the cardboard conveying process between the conveyor roller 23 and the pressure roller 24. The cardboard moves through the guide clamp 25 to the space between the conveyor roller 23 and the pressure roller 24 behind the guide clamp 25. Similarly, the corresponding second lifter 22 drives the pressure roller 24 downwards and, in conjunction with the conveyor roller 23, presses down on the cardboard. The conveyor roller 23 rotates and, in conjunction with the pressure roller 24, moves the cardboard towards the paper feeder 12. The second lifter 22 can be a telescopic cylinder. The paper feeder 12 is inclined upwards towards the second conveyor 7, forming an upwardly inclined conveying channel for the cardboard, and moves the cardboard along the paper feeder 12 to the position of the second conveyor 7 so that the tiles conveyed to the second conveyor 7 are simultaneously pressed onto the cardboard.Finally, the second lifting device 22 drives the pressure roller 24 to reset and thus continuously transports the cardboard.

[0020] Further, the upper corner alignment mechanism 3 includes a first lifting device 26, a third lifting device 27, and a second telescopic device 28. The first lifting device 26 is located below the second conveyor 7, and its output end is provided with a first lifting plate 29 extending from the second conveyor 7. The output end of the third lifting device 27 is connected to the second telescopic device 28, and the output end of the second telescopic device 28 is provided with a clamping plate 30. The upper corner alignment mechanism 3 also includes a fourth lifting device 31, a third telescopic device 32, and a fourth telescopic device 33. The fourth lifting device 31 is located on both the front and rear sides of the first lifting device 26, and its output end is connected to the third telescopic device 32. The fourth telescopic device 33 is located below the third lifting device 27, and both the output ends of the third and fourth telescopic devices are... The upper corner-wrapping centering mechanism 3 is equipped with a cardboard centering plate 34. It further includes a corner-wrapping compartment 35, a base 36, a fifth telescopic member 37, and a sixth telescopic member 38. The base 36 is located at the outlet of the corner-wrapping compartment 35. The fifth telescopic member 37 is rotatably connected to the top surface of the base 36, and its output end has a downwardly extending corner-grabbing device 39. One end of the sixth telescopic member 38 is hinged to the top surface of the base 36, and its output end is hinged to the fifth telescopic member 37. The upper corner-wrapping centering mechanism 3 also includes a bracket 40, a seventh telescopic member 41, and a centering rod 42. The bracket 40 is adjacent to the corner-wrapping compartment 35. The seventh telescopic member 41 and the centering rod 42 are respectively hinged to the bracket 40, and the output end of the seventh telescopic member 41 is hinged to one end of the centering rod 42. Figures 1 to 7As shown, the second conveyor 7 can adopt a conventional conveying structure with a conveyor wheel and a conveyor belt. A motor to drive the conveyor wheel can be installed on the frame 1. The first lifting device 26, the third lifting device 27, the fourth lifting device 31, the second telescopic device 28, the third telescopic device 32, the fourth telescopic device 33, the fifth telescopic device 37, the sixth telescopic device 38, and the seventh telescopic device 41 can all be telescopic cylinders. The tiles and cardboard are conveyed along the second conveyor 7 to the position of the first lifting device 26. The first lifting device 26 drives the first lifting plate 29 to lift the tiles and cardboard. Subsequently, the second telescopic device 28 drives the clamping plate 30 to clamp the tiles, and then the... A lifting device 26 drives the first lifting plate 29 and cardboard to reset and separate the cardboard from the tile. Immediately afterwards, the seventh telescopic device 41 drives the centering rod 42 to flip downwards and center the tile. Simultaneously, the fourth lifting device 31 drives the third telescopic device 32 to move upwards, causing the cardboard centering plate 34 of the third telescopic device 32 to extend from the second conveyor 7. The third telescopic device 32 and the fourth telescopic device 33 respectively drive their corresponding cardboard centering plates 34 to center the cardboard on the second conveyor 7, re-centering the tile and cardboard that have shifted in relative position to avoid affecting the packaging quality of the tile. The cardboard and tile are then separated. After the centering process is completed, the seventh telescopic device 41, the fourth lifting device 31, the third telescopic device 32, and the fourth telescopic device 33 reset. The third lifting device 27 moves the tile held by the clamping plate 30 downward. The second telescopic device 28 moves the clamping plate 30 back to its original position and places the tile back on the cardboard. The fifth telescopic device 37 moves the corner remover 39 from the corner remover compartment 35. The corner remover 39 can be a vacuum suction cup to pick up the corner. The sixth telescopic device 38 moves the fifth telescopic device 37 to swing towards the centered cardboard. The fifth telescopic device 37 moves the corner remover 39 towards the cardboard and makes it... The corner protector rests on the corner of the tile in the height direction. The corner protector 39 releases the corner protector and the fifth telescopic device 37 and the sixth telescopic device 38 reset. Since the gap between the separated tile and the cardboard is small, the corner protector is positioned between the tile and the cardboard after the corner protector 39 releases the corner protector, and the falling tile presses down on the corner protector, thus completing the upper corner protector work. After the tile and cardboard are covered with the upper corner protector, they continue to be conveyed to the folding mechanism 4 along the second conveyor 7. The tile centering and cardboard centering mechanisms are integrated into the upper corner protector mechanism, which can further reduce the overall length of the equipment, thereby making the overall structure more compact and integrated and reducing the overall space occupied.

[0021] Further, the origami mechanism 4 includes an eighth telescopic member 43, a ninth telescopic member 44, a tenth telescopic member 45, an eleventh telescopic member 46, and a mounting frame 47. The frame 1 is provided with a paper guide seat 48 and a guide frame 471 in front of the mounting frame 47. The frame 1 is hinged with an origami frame 49 between the two mounting frames 47 along the tile conveying direction. The eighth telescopic member 43 is hinged to the origami frame 49, and the output end of the eighth telescopic member 43 is hinged to the origami frame 49. A receiving device is provided on one side of the two mounting frames 47 facing each other. The housing 50 and the ninth telescopic device 44 are slidably connected. The housing 50 is connected to the mounting frame 47, and the output end of the ninth telescopic device 44 is connected to the housing 50. A tenth telescopic device 45 is provided inside the housing 50.

During the movement of the cardboard along the second conveyor 7, the guide frame 471 limits the cardboard. The cardboard is conveyed along the guide frame 471 to the paper guide seat 48, and the paper guide seat 48 first lifts the side components of the cardboard. When the cardboard reaches between the two receiving boxes 50, the ninth telescopic device 44 drives the receiving box 50 to extend and abuts the side of the lifted cardboard against the side wall of the brick package, making the side of the cardboard completely upright. Then, the tenth telescopic device 45 drives the folding plate 51 to extend. The folding plate 51 folds the folding plate on the upright side of the cardboard inward and inward. The folded ear rests against the corner of the wrapper. Then, the eighth telescopic device 43 drives the origami frame 49 to flip upward. The origami frame 49 may be equipped with a pressure roller. During the flipping process of the origami frame 49, the side of the paper without the folded ear will stand upright. When the origami frame 49 is flipped to a vertical position, the pressure roller on the origami frame 49 will continue to fold the upright side of the paper down and press it against the top surface of the brick wrapper. Finally, the eleventh telescopic device 46 drives the pressure frame 52 to flip downward. The pressure frame 52 folds the upright paper down and presses it against the top surface of the tile.
