Description

Technical Field

[0001] The present invention relates to the technical field of automatic packaging equipment for ceramic tiles, and particularly to a ceramic tile wrapping equipment and a ceramic tile wrapping method. Background Art

[0002] In the building ceramic industry, after the finished ceramic tiles are palletized, they need to be transported and protected by a wrapping machine. There are mainly two major technical defects in the traditional wrapping process:

[0003] First, the utilization rate of packaging materials is low. The current process requires the use of a whole piece of packaging paper with a single area larger than the bottom surface of the ceramic tile stack (usually the coverage area of the bottom surface of the paper accounts for more than 60%), and the whole package is achieved by folding the four sides. This "whole surface coverage" method causes the central area of the paper to be completely pressed under the stack bottom, and only the edge part participates in the three-dimensional wrapping, resulting in serious waste of packaging materials and significantly increasing production costs.

[0004] Second, the installation accuracy of the corner guards is limited. The existing equipment needs to first lay the packaging paper flat on the conveyor line, then stack the ceramic tile stack, and finally the transfer system moves the combination to the corner guard installation station for corner guard installation. In this process, the edge of the pre-laid paper is very likely to have spatial interference with the corner guard insertion mechanism: on the one hand, the warping or displacement of the paper will hinder the positioning of the corner guard; on the other hand, the manipulator needs to avoid the paper folding area when placing the corner guard, resulting in the corner guard not fitting tightly with the corner of the ceramic tile stack. This technological defect directly affects the integrity of the packaging and is likely to cause the corner guard to fall off or the edges and corners to be damaged during transportation.

[0005] Although the industry generally uses automatic wrapping equipment at present, the problems of the above material costs and technological defects have not been fundamentally solved for a long time. Therefore, it is urgent to develop a new wrapping technology that can significantly reduce the amount of packaging materials used and at the same time optimize the corner guard installation process to meet the dual requirements of the building ceramic industry for cost reduction, efficiency improvement and transportation safety.

[0061] The following will Figures 1 to 13 further illustrate the technical solution of the present invention in conjunction with the attached

[0062] A tile wrapping device includes a frame 1, a conveying device 2, a leveling device 3, a corner protector inserting device 4, a brick sucking and transferring device 5, a paper placing device 6, and a folding device 7. The conveying device 2, the leveling device 3, the corner protector inserting device 4, the brick sucking and transferring device 5, the paper placing device 6, and the folding device 7 are installed on the frame 1;

[0063] The conveying device 2 includes two conveying mechanisms 21. The two conveying mechanisms 21 are symmetrically arranged left and right. The two conveying mechanisms 21 form a conveying surface extending forward and backward. The conveying surface is successively provided with a leveling station, a corner protector inserting station, a paper placing station, and a folding station from back to front;

[0064] The leveling device 3 is used to level the four sides of the brick stack at the leveling station;

[0065] The corner protector inserting device 4 is used to insert corner protectors at the four corners of the brick stack at the corner protector inserting station;

[0066] The paper placing device 6 is used to place two side papers and two end papers at the paper placing station. The two side papers are symmetrically arranged left and right, and the two end papers are symmetrically arranged front and back. The two side papers and the two end papers form a packaging paper group;

[0067] The folding device 7 is used to fold and package the packaging paper group of the brick stack at the folding station;

[0068] The brick sucking and transferring device 5 is arranged above the conveying device 2. The brick sucking and transferring device 5 is used to transfer the brick stack with corner protectors inserted at the corner protector inserting station to the paper placing station.

[0069] Among them, the conveying mechanism 21 is symmetrically arranged to form a conveying surface, which can be an adjustable-width conveying channel constructed by two parallel conveyor belts to meet the transmission requirements of brick stacks of different sizes. The aligning device 3 positions the four sides of the brick stack, which can be a multi-directional platen mechanism to mechanically correct the sides and ends of the brick stack. The corner guard inserting device 4 completes the installation of corner guards at an independent station, which can use a rotating picking and placing component to accurately insert corner guard paper into the four corners of the brick stack. The brick sucking and transferring device 5 transfers the brick stack across stations, which can use a vacuum chuck component to cooperate with a linear guide rail to achieve lifting and translation movements. The paper placing device 6 separately lays the side paper and the end paper, which can use different paper picking and placing mechanisms to arrange the side paper (extending front and back) and the end paper (extending left and right) that have been restricted in position respectively. The folding device 7 sequentially folds different parts of the paper skin group to achieve three-dimensional wrapping of the brick stack.

[0070] Specifically, the brick stack is conveyed by the symmetric conveying mechanism 21 to the aligning station to complete the positioning of the front, back, left, and right sides. The corrected brick stack is conveyed into the corner guard inserting station by the conveying device 2, and the corner guards at the four corners are accurately inserted by an independent mechanism. The brick sucking and transferring device 5 lifts and transfers the brick stack with corner guards to avoid interference with the subsequent paper laying process. The paper placing device 6 separately lays the left and right side papers and the front and back end papers at the vacated paper placing station to form a packaging paper skin group that only covers the edges of the brick stack. After the brick sucking and transferring device 5 places the brick stack on the packaging paper skin group, the conveying device 2 conveys the packaging paper skin group and the brick stack to the folding station together. The folding device 7 sequentially folds the end paper, the corner, and the side paper to complete the three-dimensional wrapping of the brick stack. Each process is sequentially completed at an independent station, eliminating the spatial interference between the paper skin and the insertion of the corner guards, and the split paper structure reduces the material coverage in the central area.

[0071] Compared with the prior art, the traditional process uses a whole paper skin to be pre-laid, and then the corner guards are inserted into the brick stack placed on the paper skin. This method causes material waste on the one hand, and on the other hand, the installation process of the corner guards is also prone to interference with the pre-laid paper skin. The wrapping equipment of the present invention realizes the installation of corner guards first and then the laying of paper through process reconstruction, and the corner guards directly contact the corners of the brick stack to ensure the fitting accuracy. The split packaging paper skin group replaces the whole paper skin coverage, effectively reducing the paper consumption in the unnecessary wrapping area. The independent station setting avoids mechanical movement interference, and the folding mechanism's step-by-step action improves the quality of the wrapped shape.

[0072] Through the above technical solutions, the present application significantly reduces the consumption of the packaging paper skin, and the split structure only covers the effective wrapping area. The pre-positioning of the corner guard installation process ensures direct contact with the corners of the brick stack, eliminating the positioning deviation caused by paper skin interference. Each device operates sequentially at an independent station, improving the operation stability of the equipment and the consistency of the packaging shape.

[0073] Further, the paper placing device 6 includes a side paper placing mechanism 61, two end paper placing mechanisms 62, and a paper sucking and transferring mechanism 63;

[0074] The side paper feeding mechanism 61 is configured to convey the side paper to the paper feeding station;

[0075] Two end paper feeding mechanisms 62 are arranged opposite to each other front and back, and the two end paper feeding mechanisms 62 are disposed on the same side of the conveying device 2. The end paper feeding mechanism 62 is configured to output the end paper;

[0076] The paper suction and transfer mechanism 63 is disposed above the conveying device 2, and the paper suction and transfer mechanism 63 is configured to transfer the end paper to the paper feeding station.

[0077] The conveying surface formed by the conveying device 2 provides a reference platform for the splicing of the side paper and the end paper. The side paper feeding mechanism 61 adopts a left-right symmetric side paper arrangement method to form a strip-shaped support structure that wraps around the left and right sides of the brick stack, replacing the left and right covering areas of the traditional whole cardboard. The layout of the two end paper feeding mechanisms 62 arranged opposite to each other front and back on the same side of the conveying device 2, combined with the aerial transfer ability of the paper suction and transfer mechanism 63, enables the end paper to accurately span the conveying device 2 and vertically connect the two ends of the side paper precisely. Through the orthogonal combination of the front-back extension layout of the side paper and the left-right extension layout of the end paper, a rectangular frame structure that only covers the four sides of the brick stack is formed, and a hollow area is naturally formed in the middle area. Compared with the laying of the traditional whole cardboard, the paper consumption area can be reduced by more than 60%. As a key execution unit, the paper suction and transfer mechanism 63 realizes the lossless transfer of the end paper through the vacuum adsorption method, ensures the precise positioning of the front and rear ends of the paper at the paper feeding station, enables the end paper and the side paper to form an effective overlapping and bonding area, and guarantees the overall strength of the wrapping structure.

[0078] Through the above technical solutions, the present invention effectively solves the problem of waste materials existing in the packaging of brick stacks with whole cardboard. The frame structure of the side paper and the end paper eliminates the redundant area in the middle on the premise of ensuring the wrapping strength, and realizes the precise control of the paper consumption. The split paper feeding mechanisms of the side paper feeding mechanism 61 and the end paper feeding mechanism 62 cooperate with the paper suction and transfer mechanism 63 to ensure the precise positioning and reliable splicing of the paper skins (side paper and end paper) in the conveying process. The paper feeding device 6 not only reduces the packaging material cost, but also improves the automation degree of the wrapping operation, and adapts to the production requirements of brick stacks of different sizes.

[0079] Further, the side paper feeding mechanism 61 includes a transverse rail 611, a left paper bin 6121, a right paper bin 6122, a left paper picking member 6131, a right paper picking member 6132, and two first driving members; the left paper bin 6121 and the right paper bin 6122 extend in the front-rear direction, the left paper bin 6121 and the right paper bin 6122 are installed on the frame 1 and are respectively located on the left and right sides of the conveying device 2; the transverse rail 611 extends in the left-right direction, the transverse rail 611 is disposed below the conveying device 2, and one of the first driving members is used to drive the left paper picking member 6131 to slide along the transverse rail 611, the left paper picking member 6131 is used to obtain the side paper from the left paper bin 6121, and the left paper picking member 6131 is used to place the side paper on the left side of the paper placing station; the other first driving member is used to drive the right paper picking member 6132 to slide along the transverse rail 611, the right paper picking member 6132 is used to obtain the side paper from the right paper bin 6122, and the right paper picking member 6132 is used to place the side paper on the right side of the paper placing station;

[0080] The end paper feeding mechanism 62 includes an end paper bin 621, an end paper picking member 622, and an end paper conveying member 623; the end paper bin 621 is installed on the frame 1, and the end paper bin 621 extends in the left-right direction; the end paper conveying member 623 extends in the left-right direction, one end of the end paper conveying member 623 is located below the end paper bin 621 to form a paper inlet end, and the other end of the end paper conveying member 623 horizontally extends above the paper placing station to form a paper outlet end; the end paper picking member 622 is disposed below the end paper bin 621, the end paper picking member 622 obtains the end paper from the bottom paper outlet of the end paper bin 621, and releases the end paper to the paper inlet end of the end paper conveying member 623;

[0081] The paper suction and transfer mechanism 63 includes a paper suction and transfer mounting frame 631, a longitudinal rail 632, two paper suction and transfer members 633, and two second driving members; the paper suction and transfer mounting frame 631 is installed on the frame 1, the longitudinal rail 632 is installed on the paper suction and transfer mounting frame 631, the longitudinal rail 632 extends in the front-rear direction, one of the second driving members is used to drive one of the paper suction and transfer members 633 to slide along the longitudinal rail 632, the other second driving member is used to drive the other paper suction and transfer member 633 to slide along the longitudinal rail 632, the two paper suction and transfer members 633 are arranged opposite to each other in the front-rear direction, and the two paper suction and transfer members 633 respectively transfer the end papers output by the two end paper feeding mechanisms 62 to the paper placing station.

[0082] The horizontal track 611 is arranged below the conveying device 2. The left paper picking member 6131 and the right paper picking member 6132 move independently along the horizontal track 611. After picking up the side papers from the two side paper bins, they are directly horizontally translated to the corresponding sides of the paper placing station, avoiding the mechanical interference caused by the horizontal crossing of the conveyor belt in traditional equipment. The end paper bin adopts a layout extending left and right. The end paper conveying member 623 receives the end papers from the bottom of the end paper bin 621 and conveys them horizontally to above the paper placing station. Through the longitudinal movement of the paper suction and transfer member 633, the end of the end paper conveying member 623 is transferred to the front and rear ends of the paper placing station. During this process, the end papers are always kept on the same horizontal plane. The two paper suction and transfer members 633 are independently controlled on the longitudinal track 632. The paper suction and transfer member 633 at the front transfers the end papers at the end of the front end paper conveying member 623 to a predetermined position at the front end of the paper placing station, and the paper suction and transfer member 633 at the rear synchronously transfers the end papers at the end of the rear end paper conveying member 623 to a predetermined position at the rear end of the paper placing station. By forming a spatial vertical relationship between the longitudinal movement path and the horizontal movement path of the side papers, the risk of track crossing is eliminated.

[0083] Further, the paper suction and transfer member 633 includes a mounting seat 6331, a lifting member 6332, and a paper suction assembly 6333. The mounting seat 6331 is slidably connected to the longitudinal track 632. The lifting member 6332 is installed on the mounting seat 6331. The paper suction assembly 6333 is arranged at the driving end of the lifting member 6332. The lifting member 6332 is used to drive the paper suction assembly 6333 to move up and down. Specifically, the lifting member 6332 drives the paper suction assembly 6333 to descend to the paper outlet end of the end paper placing mechanism 62, adsorbs the end papers and then lifts. Subsequently, the mounting seat 6331 moves along the longitudinal track 632 to the target position on the conveying surface, and the lifting member 6332 drives the paper suction assembly 6333 to descend again and accurately place the end papers at the front and rear ends of the side papers.

[0084] Compared with the prior art, traditional equipment lays the side papers in a way that the single-side paper bin horizontally crosses the conveyor belt. The paper picking mechanism is prone to collide with the conveying device during the movement, and two sets of independent track systems need to be set for the symmetrical paper picking of the double paper bins. This solution realizes the collaborative operation of the bilateral paper picking members (the left paper picking member 6131 and the right paper picking member 6132) by sharing the horizontal track 611. The horizontal track 611 is arranged below the conveying device 2, which not only saves space but also avoids mechanical interference. For the transfer of the end papers, the prior art mostly adopts a direct vertical lifting method, and the paper skin is prone to sag due to gravity, resulting in positioning deviation. However, in this solution, through the combined movement of the end paper conveying member 623 extending left and right and the paper suction and transfer mechanism 63 with longitudinal transfer and vertical lifting, accurate positioning is achieved while maintaining the flatness of the paper surface.

[0085] Further, the hemming device 7 includes two end-edge hemming mechanisms 71, two side-edge hemming mechanisms 72, and four corner-folding mechanisms 73;

[0086] The two end-edge hemming mechanisms 71 are arranged at the front and rear ends of the hemming station, the two side-edge hemming mechanisms 72 are arranged on the left and right sides of the hemming station, and the four corner-folding mechanisms 73 are respectively arranged at the four diagonals of the hemming station; the two end-edge hemming mechanisms 71 are used for the first folding of the end papers at the front and rear ends, the corner-folding mechanisms 73 are used for folding the left and right sides of the end papers after the first folding, and the two side-edge hemming mechanisms 72 are used for the second folding of the side papers on the left and right sides.

[0087] The two end-edge hemming mechanisms 71 are located at the front and rear ends of the paper-folding station, and the first folding of the end papers at the front and rear ends is synchronously performed to form a preliminary wrapping at the front and rear ends of the brick stack; subsequently, the four corner-folding mechanisms 73 perform corner-folding on the end papers protruding from the left and right sides of the brick stack after the first folding at the four corners of the paper-folding station, eliminating the suspension and wrinkling phenomena during corner folding of the traditional paper-folding device; finally, the two side-edge hemming mechanisms 72 perform the second folding on the side papers located on the left and right sides of the brick stack on the left and right sides. The process of the second folding covers the corner-folding parts completed by the corner-folding mechanisms 73 before, forms a press fit on the corner-folding parts, and simultaneously completes the overall wrapping of the brick stack. The entire process establishes a basic wrapping form through the first folding, precisely processes the folding of the corners by the corner-folding mechanisms, completes the overall packaging of the brick stack through the second folding, and strengthens the wrapping stability of the corner-folding parts through the second folding, ensuring that the packaging paper group forms a tightly fitting and flat folding structure on the four sides and four corners of the brick stack, avoiding the subsequent unstable stacking problem caused by loose corner wrapping.

[0088] Furthermore, the end-edge hemming mechanism 71 includes an end-edge hemming seat 711, an end-edge hemming driving member 712, an end-edge hemming shaft 713, and a plurality of end-edge hemming members 714; the end-edge hemming shaft 713 is rotatably arranged on the top of the end-edge hemming seat 711, the end-edge hemming shaft 713 extends in the left-right direction, the plurality of end-edge hemming members 714 are arranged at intervals on the end-edge hemming shaft 713, the end-edge hemming driving member 712 is installed on the end-edge hemming seat 711, and the end-edge hemming driving member 712 is used for driving the end-edge hemming shaft 713 to rotate, so that the end-edge hemming members 714 perform the first folding on the end papers;

[0089] The corner-folding mechanism 73 includes a corner-folding driving member 731 and a corner-folding assembly 732, and the corner-folding driving member 731 is used for driving the corner-folding assembly 732 to move in the front-rear direction, so that the side part of the end paper after the first folding fits with the side part of the brick stack to form a corner;

[0090] The side flanging mechanism 72 includes a side flanging base 721, a side lifting assembly 722, and a side folding assembly 723. The second folding includes an upward folding and an inward folding. The side lifting assembly 722 is used to perform the upward folding on the side paper, and the side folding assembly 723 is used to perform the inward folding on the side paper after the upward folding is completed.

[0091] First of all, the end flanging base 711 serves as the basic support platform of the end flanging mechanism 71. A transverse rotation axis is formed by an end flanging shaft 713 extending in the left-right direction at the top. The left-right extension layout of the end flanging shaft 713 enables a plurality of spaced-apart end flanging members 714 mounted thereon to cover the entire front and rear end edges of the brick stack. The transmission system composed of the end flanging driving member 712 and the end flanging shaft 713 drives the rotation of the shaft body to drive all the end flanging members 714 to act synchronously, ensuring that the end paper is evenly stressed and the actions are synchronous during the folding process at the front and rear ends. The plurality of spaced-apart end flanging members 714 form continuously distributed force application points when the end flanging shaft 713 rotates, which can not only avoid the situation of partial non-folding but also prevent the cardboard from being damaged due to excessive pressure. This axially driven structural design is particularly suitable for long-strip folding operations. Through mechanical linkage, the cooperative operation of multiple contact points is realized, providing a flat and reliable folding foundation for the subsequent corner folding process.

[0092] After that, through the cooperation of the corner folding driving member 731 with linear driving ability and the corner folding assembly 732, the precise folding of the corner paper of the brick stack is realized. The driving characteristics of the corner folding driving member 731 enable it to accurately control the displacement of the corner folding assembly 732 in the front-rear direction, ensuring that when the corner folding assembly 732 reaches the predetermined working position, the side of the end paper that has completed the first folding is accurately pushed to be completely attached to the side surface (left side / right side) of the brick stack. The structural design of the corner folding assembly 732 enables it to gradually guide the free edge of the end paper to the side wall of the brick stack during the movement and form a corner that conforms to the geometric shape of the brick stack corner through mechanical limiting. This straight-line propulsion method in the front-rear direction avoids the problems of paper misalignment or wrinkles caused by traditional rotary folding. Especially for the wrapping of the right-angle part of the brick stack, this technical means can make the paper form a gapless and tightly wrapped corner part at the corner, thereby improving the flatness and structural stability of the corner after packaging.

[0093] Finally, the side jacking assembly 722 performs an upward movement in the vertical direction. First, it jacks up the side paper of the brick stack from the horizontal state to the vertical state. This operation not only forms a preliminary wrapping of the side of the brick stack but also enables the side paper to cover the previously formed folded corner. The side folding assembly 723 performs an inward folding in the horizontal direction on the outside of the jacked-up vertical side paper. By pushing the side paper towards the center of the brick stack, it realizes the wrapping of the (left and right) sides of the brick stack. The spatial cooperation design of the side jacking assembly 722 and the side folding assembly 723 enables the side paper of the brick stack to first form a support surface perpendicular to the side of the brick stack and then form a wrapping shape that closely fits the top surface of the brick stack through horizontal pushing. By implementing two folding actions in different directions step by step, the wrapping of the sides of the brick stack is achieved.

[0094] Through the above three steps, the overall origami wrapping of the brick stack is achieved.

[0095] Furthermore, the aligning device 3 includes two groups of aligning mechanisms, and the two groups of aligning mechanisms are respectively installed on the two conveying mechanisms 21, and the two groups of aligning mechanisms are arranged oppositely;

[0096] The aligning mechanism includes a side aligning driving member 311, a side aligning assembly 312, a rear end aligning driving member 321, a rear end aligning assembly 322, a front end aligning driving member 331, and a front end aligning assembly 332; the side aligning driving member 311 is installed on the outside of the conveying mechanism 21, and the side aligning driving member 311 is used to drive the side aligning assembly 312 to move to the side of the brick stack and align the side of the brick stack; the rear end aligning driving member 321 is installed on the outside of the conveying mechanism 21, and the rear end aligning driving member 321 is used to drive the rear end aligning assembly 322 to move to the rear end of the brick stack and align the rear end of the brick stack; the front end aligning driving member 331 is installed at the lower part inside the conveying mechanism 21, and the front end aligning driving member 331 is used to drive the front end aligning assembly 332 to rise to the front end of the brick stack and align the front end of the brick stack.

[0097] Specifically, when the brick stack enters the aligning station, two groups of aligning mechanisms are started synchronously. The side aligning driving member 311 pushes the side aligning assembly 312 towards the side of the brick stack, and the side aligning assemblies 312 on both sides clamp the side of the brick stack symmetrically, aligning the two sides of the multiple tiles stacked layer by layer respectively. The rear end aligning driving member 321 drives the rear end aligning assembly 322 towards the rear end of the brick stack, and the front end aligning driving member 331 drives the front end aligning assembly 332 towards the front end of the brick stack. The aligning structures at the front and rear ends act on the front and rear ends of the brick stack together to jointly perform the aligning operation at the front and rear ends. The three groups of driving members are distributed in the vertical direction of space. The side and rear end driving mechanisms move along different axes in the horizontal plane, and the front end driving mechanism moves in the vertical direction, forming a three-dimensional positioning system.

[0098] Furthermore, the brick sucking and transferring device 5 includes a brick sucking and conveying mechanism 51, a brick sucking and transferring seat 52, a brick sucking and lifting mechanism 53, and a brick sucking and transferring assembly 54;

[0099] The brick sucking and conveying mechanism 51 is installed on the rack 1. The brick sucking and conveying mechanism 51 extends in the front-rear direction above the inserting corner guard station and the paper placing station. The brick sucking and transferring seat 52 is installed at the movable end of the brick sucking and conveying mechanism 51. The brick sucking and conveying mechanism 51 is used to drive the brick sucking and transferring seat 52 to move in the front-rear direction. The brick sucking and lifting mechanism 53 is installed on the brick sucking and transferring seat 52, and the brick sucking and transferring assembly 54 is installed at the driving end of the brick sucking and lifting mechanism 53. The brick sucking and lifting mechanism 53 is used to drive the brick sucking and transferring assembly 54 to move up and down, and the brick sucking and transferring assembly 54 is used to adsorb the brick stack.

[0100] The brick sucking and conveying mechanism 51 refers to a horizontal moving device arranged above the inserting corner guard station and the paper placing station, which can be realized by a synchronous belt drive system or a linear slide rail mechanism. By limiting the transfer direction of the brick stack to a single front-rear axis, this mechanism avoids the misalignment of the packaging paper group and the position of the brick stack caused by lateral offset. The brick sucking and transferring seat 52 refers to a bearing structure slidably connected to the brick sucking and conveying mechanism 51. The brick sucking and lifting mechanism 53 refers to a power unit that drives the brick sucking and transferring assembly 54 to move vertically, which can be realized by a cylinder or a servo electric cylinder (but not limited to the above specific driving devices). The brick sucking and lifting mechanism 53 lifts the brick stack to a safe height above the conveying surface during the transfer process. The brick sucking and transferring assembly 54 refers to an execution component that adsorbs the brick stack, which can be realized by a vacuum chuck array or an electromagnetic chuck. This component acts directly on the surface of the brick stack.

[0101] Specifically, after the corner guards are installed at the corner guard inserting station for the brick stack, the brick sucking and transferring assembly 54 descends to the surface of the brick stack under the drive of the brick sucking lifting mechanism 53 and sucks the brick stack through negative pressure. Subsequently, the brick sucking lifting mechanism raises the brick stack to a safe height above the conveying surface, and the brick sucking conveying mechanism 51 drives the brick sucking transfer seat 52 to translate in the front-rear direction to above the paper placing station. At this time, the paper placing device 6 has laid the side paper and the end paper to form a packaging paper skin group, and the brick sucking lifting mechanism 53 controls the brick stack to be precisely lowered to the central area of the paper skin group. During the transfer process, the brick stack is always in a suspended state, avoiding contact with the conveying surface or the paper skin, thereby eliminating the risk of displacement of the packaging material caused by friction.

[0102] Further, the conveying mechanism 21 is movably installed on the frame 1 in the left-right direction.

[0103] By means of the adjustable conveying mechanism 21, a conveying channel with an adjustable width is constructed to adapt to the transmission requirements of brick stacks of different sizes.

[0104] Further, the corner guard inserting device 4 includes four corner guard inserting mechanisms, and the four corner guard inserting mechanisms are respectively arranged at the four diagonals of the corner guard inserting station;

[0105] The corner guard inserting mechanism includes a corner guard mounting plate 41, a corner guard paper bin 42 and a corner guard inserting member 43. The corner guard paper bin 42 and the corner guard inserting member 43 are mounted on the corner guard mounting plate 41; the corner guard paper bin 42 is used for storing corner guard paper materials; the corner guard inserting member 43 includes a picking and placing assembly 431 and a rotation driving unit 432. The rotation driving unit 432 is used to drive the picking and placing assembly 431 to move between the corner guard paper bin 42 and the corner of the brick stack, and the picking and placing assembly 431 is used for picking and placing a single corner guard paper material.

[0106] The four corner guard inserting mechanisms are independently arranged corresponding to the four corner spaces of the brick stack, and each corner guard paper bin 42 continuously supplies corner guard paper materials to the picking and placing assembly 431. The rotation driving unit 432 drives the picking and placing assembly 431 to complete three-dimensional motion: during the corner inserting process, the rotation driving unit 432 first drives the picking and placing assembly 431 to rotate, so that the picking part of the picking and placing assembly 431 is aligned with the discharge port of the corner guard paper bin 42 to realize the material picking action from the corner guard paper bin 42. Then the rotation driving unit 432 drives the picking and placing assembly 431 to rotate again, so that the picking and placing assembly 431 with the obtained corner guard paper is aligned with the corner of the brick stack and inserts the corner guard paper into the corner of the brick stack. This path planning enables the corner guard paper transfer and insertion / installation process to be completely before the paper placing process, avoiding the risk of interference with the paper skin during the insertion of the corner guard paper, resulting in wrinkles or tearing of the paper skin.

[0107] A method for wrapping ceramic tiles, which is used in the above-mentioned ceramic tile wrapping equipment, includes the following steps:

[0108] The brick stack is conveyed to the aligning station by the conveying device 2, and the four sides of the brick stack are aligned by the aligning device 3;

[0109] After the brick stack is aligned, it is conveyed to the corner guard inserting station by the conveying device 2, and corner guards are inserted at the four corners of the brick stack by the corner guard inserting device 4; The corner guard installation process is carried out prior to the paper laying, so that the corner guard inserting device does not need to consider the position deviation of the edge of the wrapping paper, and the corner guard paper material can be directly attached to the exposed corners of the brick stack.

[0110] The brick stack lifting and transferring device 5 sucks up the brick stack after the corner guards are inserted from above the corner guard inserting station, and transfers the brick stack above the paper laying station to wait for the paper laying device to complete the paper laying; After the corner guards are inserted, the brick stack lifting and transferring device lifts the brick stack above the paper laying station and hovers. After the side papers on both sides and the end papers at both ends are laid, the brick stack is accurately lowered to the center position of the paper skin group.

[0111] The paper laying device 6 lays two symmetric side papers and two symmetric end papers at the paper laying station and forms a wrapping paper skin group; The split paper skin group is composed of independently laid side papers and end papers. The side papers are symmetrically arranged along the left and right sides of the brick stack, and the end papers are symmetrically arranged in the front and back directions. The four papers form a discontinuous covering area at the bottom of the brick stack.

[0112] The brick stack lifting and transferring device 5 places the brick stack on the wrapping paper skin group;

[0113] The brick stack and the wrapping paper skin group are conveyed to this side station by the conveying device 2, and the folding device 7 folds the wrapping paper skin group of the brick stack for packaging to realize the wrapping of the brick stack. The folding process is carried out by a staged folding operation. First, the end paper is longitudinally folded to form a fold angle, and then the side paper is transversely folded to realize a three-dimensional wrapping.

[0114] The wrapped brick stack is sent out of the equipment by the conveying mechanism and enters the next link (such as bundling or labeling).

[0115] Compared with the prior art, the traditional process uses the method of pre-laying the whole paper skin, which causes the need to adjust the movement trajectory of the robotic arm to avoid colliding with the edge of the paper skin during the insertion of the corner guards. However, in this method, the corner guard installation and the paper laying are separated by inverting the process sequence, directly eliminating the problem of spatial interference. In addition, in the prior art, the central area of the whole paper skin is completely covered by the brick stack and cannot be reused, while the split paper skin group in this method only covers the edge area of the brick stack, reducing the ineffective covering area by more than 60%.

[0116] The technical principles of the present invention have been described above in connection with specific embodiments. These descriptions are only for explaining the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present invention without creative efforts, and these embodiments will fall within the scope of protection of the present invention.
