Description

Technical Field

[0001] This utility model relates to the field of ceramic tile wrapping technology, and in particular to a paper feeding device for ceramic tile wrapping. Background Technology

[0002] In the field of building ceramics production, cardboard wrapping is commonly used for the transportation and protection of tile stacks. The traditional method requires laying a sheet of cardboard, larger than the bottom of the tile stack, on the conveyor line. The stacked tiles are then placed in the center of the cardboard and transported to the folding station, where a folding mechanism folds and wraps the cardboard around the four sides, achieving complete sealing protection for the bottom and sides of the stack. While this process effectively protects the edges and corners of the tiles, the entire sheet of cardboard must completely cover the bottom of the stack (typically occupying more than 60% of the total cardboard area), resulting in high packaging material costs. Especially for large-scale tile manufacturers, cardboard consumption has become a core component of packaging costs. To reduce material costs, the industry urgently needs a new wrapping solution.

Therefore, they should not be construed as limitations on this utility model.

[0039] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0040] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The following is in conjunction with the appendix Figures 1 to 8 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0042] A paper feeding device for wrapping ceramic tiles includes a frame 1, a conveying mechanism 2, a side paper feeding mechanism 3, two end paper feeding mechanisms 4, and a paper suction and transfer mechanism 5. The conveying mechanism 2, the side paper feeding mechanism 3, the end paper feeding mechanism 4, and the paper suction and transfer mechanism 5 are respectively installed on the frame 1.

[0043] The conveying mechanism 2 extends in the front-to-back direction, and the top surface of the conveying mechanism 2 forms a conveying surface;

[0044] The side paper feeding mechanism 3 is used to feed two side papers to the conveying surface. The two side papers are placed symmetrically from left to right and extend in the front-back direction.

[0045] The two end paper feeding mechanisms 4 are arranged opposite each other and are located on the same side of the conveying mechanism 2. The end paper feeding mechanism 4 is used to output end paper to the conveying mechanism 2, and the end paper extends in the left-right direction.

[0046] The paper suction and transfer mechanism 5 is located above the conveying mechanism 2, and the paper suction and transfer mechanism 5 is used to transfer the end paper to the conveying surface.

[0047] The conveying mechanism 2 provides a reference platform for the splicing of side and end papers, and its forward and backward extension characteristics match the direction of tile transport. The side paper feeding mechanism 3 uses a symmetrical arrangement to form a long, strip-shaped support structure that wraps around the left and right sides of the tile, replacing the traditional left and right coverage area of ​​a single sheet of cardboard. Two end paper feeding mechanisms 4 are positioned opposite each other on the same side of the conveying mechanism 2, and, in conjunction with the air transfer capability of the suction and transfer mechanism 5, allow the end papers to accurately cross the conveying mechanism 2 and vertically connect to both ends of the side papers. Through the orthogonal combination of the forward and backward extension of the side papers and the left and right extension of the end papers, a rectangular frame structure covering only the four sides of the tile is formed, naturally creating a hollow space in the middle. Compared to the traditional laying of a single sheet of cardboard, this reduces the paper area used by more than 60%. The suction and transfer mechanism 5, as a key execution unit, achieves non-destructive transfer of the end papers through vacuum adsorption, ensuring precise positioning of the paper after crossing the conveying mechanism, and creating an effective overlapping and bonding area between the end papers and side papers, thus ensuring the overall strength of the wrapping structure.

[0048] Through the above technical solution, this utility model effectively solves the problem of material waste in packaging ceramic tiles with whole pieces of cardboard. The frame structure of the side paper and end paper eliminates redundant areas in the middle while ensuring wrapping strength, achieving precise control of paper usage. The separate paper feeding mechanisms of the side paper feeding mechanism 3 and the end paper feeding mechanism 4, together with the paper suction and transfer mechanism 5, ensure the precise positioning and reliable splicing of the cardboard (side paper and end paper) during the conveying process. This device not only reduces packaging material costs but also improves the automation level of the wrapping operation, adapting to the production needs of ceramic tiles of different sizes.

[0049] Furthermore, the side paper feeding mechanism 3 includes a transverse track 31, a left paper bin 321, a right paper bin 322, a left paper picking component 331, a right paper picking component 332, and two first driving components;

[0050] The left paper compartment 321 and the right paper compartment 322 are used to store a plurality of the side papers. The left paper compartment 321 and the right paper compartment 322 are installed on the frame 1 and extend in the front-back direction. The left paper compartment 321 is located on the left outer side of the conveying mechanism 2, and the right paper compartment 322 is located on the right outer side of the conveying mechanism 2.

[0051] The transverse track 31 extends in the left-right direction and is located below the conveying mechanism 2. One of the first driving members is used to drive the left paper-picking member 331 to slide along the transverse track 31. The left paper-picking member 331 is used to pick up the side paper from the left paper bin 321 and to place the side paper to the left side of the conveying surface. The other first driving member is used to drive the right paper-picking member 332 to slide along the transverse track 31. The right paper-picking member 332 is used to pick up the side paper from the right paper bin 322 and to place the side paper to the right side of the conveying surface.

[0052] The transverse track 31 refers to a sliding track extending in the left-right direction, which can be implemented using a linear guide or a chute structure. It is positioned below the conveying mechanism 2 to save space. The left paper bin 321 and right paper bin 322 refer to paper storage containers placed on the left and right sides of the conveying mechanism 2, respectively. They can be implemented using a stacked paper storage rack structure, with a front-to-back extension layout so that the paper storage direction is consistent with the (tile) conveying direction. The first driving component refers to the power source that drives the side paper picking components (left paper picking component 331 and right paper picking component 332) to move laterally. It can be implemented using a servo motor with a gear and rack structure or a cylinder push rod structure. Independently driving the side paper picking components can achieve bidirectional synchronous paper picking action. The left paper picking component 331 and right paper picking component 332 refer to the paper picking execution mechanisms corresponding to the left paper bin 321 and right paper bin 322, respectively. They can be implemented using a vacuum suction cup assembly with a lifting device, which transfers the side paper from the paper bin to a predetermined position on the conveying surface through lateral movement.

[0053] By setting up a separate paper bin structure with corresponding side paper-picking components, precise separate conveying of the side paper in the ceramic tile wrapping process is achieved. The vertical spatial layout of the transverse track 31 and the conveying mechanism 2 allows the left paper-picking component 331 and the right paper-picking component 332 to operate independently on the same horizontal plane. The layout design of the left paper bin 321 and the right paper bin 322 placed on both sides of the conveying mechanism 2 creates a spatial correspondence between the storage position and the final laying position of the side paper. The independent control of the left paper-picking component 331 and the right paper-picking component 332 by the two first drive components ensures synchronous or asynchronous conveying of the paper picking actions on both sides, as well as positional accuracy. The sliding trajectory design of the left paper-picking component 331 and the right paper-picking component 332 on the transverse track 31 allows the side paper to be directly moved to the predetermined position on the conveying surface along the shortest path after being taken out of the paper bin. This separate paper feeding mechanism avoids the use of whole sheets of paperboard. By independently controlling the conveying process of the left and right side paper, it ensures both the symmetry of paper laying and precise control of material usage.

[0054] Furthermore, the left paper compartment 321 and the right paper compartment 322 are paper compartments 320 with the same structure. The top of the paper compartment 320 is provided with a paper inlet, and the bottom of the paper compartment 320 is provided with a paper outlet.

[0055] The left paper-taking component 331 and the right paper-taking component 332 are structurally identical side paper-taking components 330. The side paper-taking component 330 includes a first mounting base 3301, a first lifting drive component 3302, and a first paper-suction assembly 3303. The bottom of the first mounting base 3301 is slidably connected to the transverse track 31. The first lifting drive component 3302 is disposed on the top surface of the first mounting base 3301. The first paper-suction assembly 3303 is disposed at the driving end of the first lifting drive component 3302. The first lifting drive component 3302 is used to drive the first paper-suction assembly 3303 to rise and fall. The first paper-suction assembly 3303 is used to suck up the side paper from the paper outlet.

[0056] The paper inlet refers to the opening structure located at the top of the paper tray 320 for replenishing paper stacks. It can be implemented using a rectangular through-slot structure, the width of which can be adapted to standard cardboard sizes. The paper outlet refers to the opening structure located at the bottom of the paper tray 320 for retrieving single sheets of side paper. It can be implemented using a through-hole coaxial with the paper inlet but slightly smaller in size. Specifically, the left paper tray 321 and the right paper tray 322 adopt the same structural design, eliminating the spare parts management difficulties caused by the traditional differences between left and right side structures. Simultaneously, the vertical through-slot design of the top paper inlet and the bottom paper outlet ensures stable stacking and orderly output of paper stacks. When side paper needs to be replenished, the operator vertically stacks the side paper through the paper inlet at the top of the paper tray 320, and the paper stack sinks to the bottom paper outlet due to its own weight. Furthermore, the size of the paper tray 320 is adjustable to accommodate side paper of different sizes.

[0057] Regarding the side-mounted paper-picking component 330, precise lateral positioning is achieved through the sliding connection between the first mounting base 3301 and the transverse track 31. This, combined with the vertical movement control of the first paper-suction assembly 3303 by the first lifting drive 3302, forms a three-dimensional precise positioning system. Furthermore, the first paper-suction assembly 3303 can be a negative pressure adsorption device composed of a vacuum generator and suction cups. Specifically, it can employ a multi-hole suction cup array with pressure sensors. For example, each suction cup unit can independently control the adsorption force. This assembly achieves the separation of single-sheet side paper through vacuum adsorption. Specifically, the side-mounted paper-picking component 330 moves along the transverse track 31 under the drive of the first drive to directly below the target paper tray 320. The first lifting drive 3302 then raises the first paper-suction assembly 3303 to the paper outlet position. After the suction cup array contacts the bottom cardboard, negative pressure adsorption is activated. At this time, the upper cardboard remains stationary due to its own weight, achieving single-sheet paper picking. After the cardboard has been adsorbed, it moves downward with the first paper suction assembly 3303 and leaves the paper outlet. Then, the transverse track 31 transports the side paper picking component 330 to the outside (left or right) of the conveying mechanism 2. The first lifting drive 3302 then drives the first paper suction assembly 3303, which has adsorbed the cardboard, to rise to the designated position on the conveying surface. After the negative pressure is released, the cardboard is accurately placed in the set area. The specially designed first paper suction assembly 3303 acts directly on the paper outlet of the paper bin 320, using negative pressure adsorption to achieve single-sheet paper picking, avoiding paper wrinkles or displacement that may be caused by mechanical grippers.

[0058] Furthermore, the end paper feeding mechanism 4 includes an end paper bin 41, an end paper picking component 42, and an end paper conveying component 43;

[0059] The end paper tray 41 is installed on the frame 1. The end paper tray 41 extends in the left and right direction. The top of the end paper tray 41 is provided with a paper inlet and the bottom of the end paper tray 41 is provided with a paper outlet.

[0060] The end paper conveying component 43 extends in the left and right direction. One end of the end paper conveying component 43 is located below the end paper bin 41 to form an inlet end, and the other end of the end paper conveying component 43 extends horizontally to the top of the conveying mechanism 2 to form an outlet end.

[0061] The end paper picking component 42 is located below the end paper compartment 41. The end paper picking component 42 picks up the end paper from the paper outlet of the end paper compartment 41 and releases the end paper to the paper inlet end of the end paper conveying component 43.

[0062] The end paper compartment 41 refers to a container structure for vertically stacking and storing the end paper extending to the left and right. Specifically, it can be implemented as a rectangular compartment with a bottom paper outlet. Its left and right extension layout keeps the paper in a preset posture perpendicular to the conveying direction.

[0063] The end-sheet picking component 42 is an extraction device that separates individual sheets of paper. It is located below the end-sheet compartment 41. After picking up a single sheet of end-sheet paper from the bottom outlet of the end-sheet compartment 41, the end-sheet paper falls into the inlet end of the end-sheet conveying component 43. Since the end-sheet conveying component 43 adopts a left-right extension layout, with its outlet end extending above the conveying mechanism 2, the single sheet of end-sheet paper taken out from the end-sheet compartment 41 always maintains a left-right extension state consistent with the final laying direction. It is conveyed from the inlet end to the outlet end, providing a directionally compatible connection position for the subsequent paper suction and transfer mechanism 5. Through the three-stage structure of compartment storage, bottom paper picking, and lateral conveying, the end-sheet paper is ensured to maintain a preset direction during the transfer process, achieving precise overlap and positioning with the side paper.

[0064] Furthermore, the paper conveying component 43 includes a paper feeding trough 431 and a conveying assembly 432. The paper feeding trough 431 is vertically connected, and the conveying assembly 432 is disposed on one side of the paper feeding trough 431. The conveying assembly 432 is used to convey the material located in the paper feeding trough 431.

[0065] The paper feeding component 42 includes a second lifting drive 421 and a second paper suction assembly 422. The second paper suction assembly 422 is located at the driving end of the second lifting drive 421. The second lifting drive 421 is used to drive the second paper suction assembly 422 to move up and down in the paper feed trough 431.

[0066] The vertically continuous design of the paper feed trough 431 allows the end paper to be vertically picked up by the second paper suction assembly 422, preventing paper misalignment caused by horizontal movement. The conveying assembly 432, located on one side of the paper feed trough 431, uses a unidirectional conveyor belt or roller structure to directionally push the material, ensuring the end paper is stably conveyed along a predetermined path to the output end. The linkage design between the second lifting drive 421 and the second paper suction assembly 422 enables precise paper retrieval from the bottom of the end paper bin 41, followed by vertical descent to the paper inlet end of the paper feed trough 431, and then horizontal transfer via the conveying assembly 432. This process minimizes manual intervention and prevents multiple sheets of paper from sticking together or tilting.

[0067] Specifically, the second paper suction assembly 422, driven by the second lifting drive 421, rises vertically to the bottom of the end paper compartment 41, suctions a single sheet of end paper, and then descends to the paper inlet end of the paper feed trough 431. At this time, the conveying assembly 432 starts, pushing the end paper along the paper feed trough 431 to the paper outlet end through the unidirectional movement of the conveyor belt 4322. The through structure of the paper feed trough 431 provides the second paper suction assembly 422 with uninterrupted lifting space, while the single-sided conveying assembly 432, while maintaining the integrity of the trough structure, controls the paper's trajectory through unidirectional thrust. When the end paper reaches the end of the paper feed trough 431, the paper suction and transfer mechanism performs a transfer action, accurately placing it at a predetermined position on the conveying surface.

[0068] Furthermore, the conveying assembly 432 includes a second driving member, a driving wheel 4321, a driven wheel, and a conveyor belt 4322. The driving wheel 4321 is located at one end of the paper feeding trough 431, and the driven wheel is located at the other end of the paper feeding trough 431. The conveyor belt 4322 is wrapped around the outside of the driving wheel 4321 and the driven wheel. The second driving member is used to drive the driving wheel 4321 to rotate.

[0069] The driving wheel 4321 and the driven wheel are positioned at both ends of the paper feed trough 431 to form a rigid support, ensuring the stable tension of the conveyor belt 4322. The design of the conveyor belt 4322 being wound around the outside of the two wheels ensures that the running trajectory of the conveyor belt 4322 perfectly matches the length direction of the paper feed trough 431.

[0070] The driving wheel 4321 and the driven wheel are positioned at the beginning and end of the paper feeding trough 431 respectively, forming a stable support structure. Continuous cyclic transmission is achieved through the closed loop of the conveyor belt 4322. When the second driving member drives the driving wheel 4321 to rotate, the conveyor belt 4322 moves at a uniform speed along the length of the paper feeding trough 431. When the end paper is placed in the paper feeding trough 431, the bottom surface of the end paper contacts the conveyor belt 4322 and moves synchronously with the conveyor belt 4322 under the action of friction.

[0071] Furthermore, the paper suction and transfer mechanism 5 includes a mounting frame 51, a longitudinal track 52, two paper suction and transfer components 53, and two third drive components;

[0072] The mounting frame 51 is mounted on the frame 1, and the longitudinal track 52 is mounted on the mounting frame 51. The longitudinal track 52 extends in the front-to-back direction. One of the third driving members is used to drive one of the paper suction and transfer members 53 to slide along the longitudinal track 52, and another third driving member is used to drive another paper suction and transfer member 53 to slide along the longitudinal track 52. The two paper suction and transfer members 53 are arranged opposite each other, and the two paper suction and transfer members 53 respectively transfer the end paper output by the two end paper feeding mechanisms 4 to the conveying surface.

[0073] The longitudinal track 52 refers to a straight track structure extending along the conveying direction. The third driving component refers to the power device that controls the movement of the paper suction and transfer component 53. For example, a combination of a stepper motor and a lead screw can be used, where the motor rotation drives the lead screw to achieve high-precision displacement control. The paper suction and transfer component 53 refers to an execution unit that includes a suction function. After suctioning the end paper with a vacuum suction cup, it moves along the longitudinal track 52 to a predetermined position and is released.

[0074] Specifically, the extension direction of the longitudinal track 52 corresponds spatially to the front and rear extension layout of the conveying mechanism 2, enabling the paper-absorbing transfer member 53 to move horizontally along the tile conveying direction. Two independently controlled third drive units drive the front and rear paper-absorbing transfer members 53 respectively. When the end paper feeding mechanism 4 completes the end paper output, the front paper-absorbing transfer member 53 moves along the longitudinal track 52 to the front end paper for adsorption, and the rear paper-absorbing transfer member 53 moves synchronously or delayed to the rear end paper position to complete adsorption. After the adsorption action is completed, the two paper-absorbing transfer members carry the end paper and move along the longitudinal track 52 to the predetermined position on the conveying surface. The front paper-absorbing transfer member 53 places the end paper in front of the side paper to form a cross overlap, and the rear paper-absorbing transfer member 53 places another end paper in the back of the side paper to form a corresponding overlap, thereby realizing the cross overlap structure of two side papers and two end papers.

[0075] Furthermore, the paper-absorbing and transferring component 53 includes a second mounting base 531, a third lifting component 532, and a third paper-absorbing assembly 533. The second mounting base 531 is slidably connected to the longitudinal track 52. The third lifting component 532 is mounted on the second mounting base 531. The third paper-absorbing assembly 533 is located at the driving end of the third lifting component 532. The third lifting component 532 is used to drive the third paper-absorbing assembly 533 to move up and down.

[0076] By configuring a second mounting base 531 with longitudinal sliding capability and a third paper suction assembly 533 with lifting drive, precise spatial positioning and transfer of the end paper is achieved. The sliding connection between the second mounting base 531 and the longitudinal track 52 allows the paper suction transfer component 53 to be adjusted in position along the conveying direction. The vertical movement of the third lifting component 532 controls the height change of the third paper suction assembly 533, ensuring that the end paper can accurately detach from the conveying mechanism 2 and descend to the predetermined laying position during the transfer process.

[0077] Specifically, the third lifting component 532 drives the third paper suction assembly 533 to descend to the paper output end of the end paper conveying component 43, and lifts it after adsorbing the end paper. Then, the second mounting base 531 moves along the longitudinal track 52 to the target position on the conveying surface, and the third lifting component 532 drives the third paper suction assembly 533 to descend again and accurately place the end paper at both ends of the side paper.

[0078] Furthermore, the third suction paper assembly 533 includes a third suction cup mounting base and a plurality of suction cups, the third suction cup mounting base extending in the left-right direction, and the plurality of suction cups being spaced apart on the third suction cup mounting base.

[0079] The suction cup mounting bases, extending in the left-right direction, ensure that the coverage area of ​​the third paper suction assembly 533 matches the lateral dimension of the end paper, guaranteeing full coverage of the end paper during suction operations. The spaced-apart suction cups, through a discrete suction point layout, avoid paper deformation that might occur with continuous suction, and create a multi-point balanced suction force during end paper transfer, effectively preventing paper shifting or falling off.

[0080] A paper feeding method, used in the aforementioned paper feeding device, includes the following steps:

[0081] Step 1: The side paper feeding mechanism 3 feeds two side papers to the conveying surface, with the two side papers placed symmetrically on the left and right sides. The side paper feeding mechanism 3 precisely positions the two side papers, which extend forward and backward, on the left and right sides of the conveying surface, forming the side support frame of the bottom of the tile.

[0082] Step 2: The two end paper feeding mechanisms 4 respectively transport the left and right extended end paper to the position to be transferred;

[0083] Step 3: The paper suction and transfer mechanism 5 transfers a piece of end paper from the output end of the end paper feeding mechanism 4 to the conveying surface and places it in front of two side papers, with the left and right ends of the end paper overlapping the side papers at both ends.

[0084] The paper suction and transfer mechanism 5 transfers another end paper from the output end of the other end paper feeding mechanism 4 to the conveying surface and places it behind the two side papers, with the left and right ends of the end paper overlapping the side papers at both ends.

[0085] Two side sheets and two end sheets are combined to form a rectangular cardboard with a hollowed-out center.

[0086] The paper-collecting and transferring mechanism 5 picks up the end paper from both the front and rear directions and precisely places it in the predetermined overlapping area of ​​the side paper through a lifting and translating motion. The left and right edges of the front end paper cover the front sections of the left and right side papers, respectively, and the left and right edges of the rear end paper cover the rear sections of the left and right side papers, respectively. The overlapping area of ​​the four papers forms a closed rectangular frame, and the hollowed-out area in the middle corresponds to the center area of ​​the bottom surface of the tile. Material savings are achieved by reducing the paper coverage in this area.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
