Technical Field

[0001] The present invention relates to the technical field of the production and profiling process of colored stone metal tiles, and particularly relates to a method for profiling metal tiles and its production line. Background Art

[0002] Colored stone metal tiles are a new type of high-grade roofing material with a galvanized aluminum-zinc steel plate with excellent anti-corrosion performance as the substrate, an acrylic resin with extremely strong weather resistance as the adhesive, and colored natural gravel as the surface layer. Because of its beauty, lightness, durability, and environmental protection, it has become a building material for high-grade buildings in recent years. The production and profiling process of colored stone metal tiles is an important link in the production line of colored stone metal tiles. The entire profiling process consists of three processes: feeding and slitting, trimming the lace, and profiling. At present, the production and profiling process of colored stone metal tiles are all produced by manual tile pressing, with low efficiency and high rejection rate.

The decoiler is responsible for providing the steel coil, the cutting device completes the laser cutting work, the cut sheet is profiled by the press, and finally output through the finished tile conveyor. Its degree of mechanization is high and its flexibility is good, greatly reducing the labor intensity of workers. However, there are many deficiencies in the cooperation between the above automatic tile pressing production lines, especially the cooperation between feeding, cutting, feeding, and profiling is not smooth enough, resulting in insufficient automation.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] This embodiment discloses a metal tile forming method, such as Figures 1 to 7 As shown, the following steps are included:

[0040] S1, conveying the steel coil material to the sheet processing area, and stopping the conveying when the preset length is reached;

[0041] S2, trimming and cutting the steel coil material in the sheet processing area to form a sheet 35, and conveying the sheet 35 to the base tile pressing area;

[0042] S3. During the transportation process:

[0043] When the material sheet 35 completely passes through the feeding sensing area, steps S1 and S2 are repeated, and the material sheet 35 is continuously fed;

[0044] When the sheet 35 reaches the feeding protection area, if the profiling mechanism of the base tile profiling area is above the lowest profiling cycle position at this time, the sheet 35 will continue to be conveyed. If the profiling mechanism is below the lowest profiling cycle position at this time, the conveying of the sheet 35 will be suspended first, and the profiling mechanism will be started. When the profiling mechanism moves upward and exceeds the lowest profiling cycle position, the profiling mechanism will be suspended and the sheet 35 will continue to be conveyed.

[0045] After the sheet 35 completely passes through the profiling induction area, start the profiling mechanism to profile the sheet 35 to form a basic tile;

[0046] S4. When the profiling mechanism after profiling reaches the highest profiling cycle position, convey the basic tile outwards and pause the profiling mechanism;

[0047] S5. Repeat steps S3 and S4 until the preset number of basic tiles is completed.

[0048] Furthermore, in this embodiment, as Figures 1 to 7 shown, it further includes the following steps: In step S3, before the sheet 35 reaches the profiling induction area and after passing through the sheet gripping induction area, grip the sheet 35 into the basic tile profiling area, and the gripping method can make the sheet 35 in place accurately.

[0049] Furthermore, in this embodiment, as Figures 1 to 7 shown, between step S1, it further includes step S0. In step S0, a steel coil material for conveying to the sheet processing area is pre-stored in the temporary storage area; in step S1, when there is no steel coil material in the temporary storage area, repeat step S0.

[0050] Embodiment 2

[0051] This embodiment discloses a metal tile profiling production line, which is mainly applied to the metal tile profiling method in Embodiment 1. As Figures 1 to 7 shown, it includes an unwinder 1, a lengthwise feeder 2, a sheet cutter 3, a sheet conveying device, a basic tile profiler 6, and a basic tile outfeed device arranged in sequence. Along the steel coil conveying direction on the sheet conveying device, there are a feeding photoelectric sensor 11 and a protection photoelectric sensor 12 arranged in sequence. The feeding photoelectric sensor 11 is signal-connected to the lengthwise feeder 2, and the protection photoelectric sensor 12 is signal-connected to the sheet conveying device. At the feeding end of the basic tile profiler 6, there is a profiling photoelectric sensor 14, and on the basic tile profiler 6, there are also an upper proximity switch 15, a middle proximity switch 16, and a lower proximity switch 17 arranged from top to bottom. Among them, the sheet cutter 3 has a sheet processing area. The unwinder 1 and the lengthwise feeder 2 cooperate to convey the steel coil material to the sheet cutter 3 with a sheet processing area at a preset length; the basic tile profiler 6 is provided with a basic tile profiling area, and the sheet 35 processed in the sheet processing area is conveyed to the basic tile profiler 6 through the sheet conveying device; the feeding photoelectric sensor 11 and the protection photoelectric sensor 12 respectively form a feeding induction area and a feeding protection area on the sheet conveying device, the profiling photoelectric sensor 14 forms a profiling induction area, and the upper proximity switch 15 and the lower proximity switch 17 respectively form the lowest profiling cycle position and the highest profiling cycle position on the basic tile profiler 6.

[0052] Specific working process:

[0053] First, start the uncoiler 1. After releasing a certain length of steel coil, it stops working. Then, start the fixed-length feeder 2. After conveying a preset length of steel coil to the sheet cutter 3 according to the designed size of the workpiece, it stops working and sends a shearing signal to the sheet cutter 3;

[0054] Then, the sheet cutter 3 trims the edges and makes cross-cuts to cut the steel coil into sheets 35 with lace, and at the same time conveys the sheets 35 to the corrugated tile press 6 through the sheet conveying device;

[0055] Then, during the conveying process:

[0056] When the sheet 35 completely passes through the feeding photoelectric sensor 11, the signal is transmitted to the fixed-length feeder 2. The fixed-length feeder 2 starts to convey the steel coil again. When the set length is reached, the fixed-length feeder 2 stops running again and sends a shearing signal to the sheet cutter 3 to enter the next working cycle; With the conveying of the sheet conveying device, the sheet 35 after passing through the feeding photoelectric sensor 11 will first block the protection photoelectric sensor 12. If the corrugating mechanism of the corrugated tile press 6 is below (including the position of the lower proximity switch 17) the lower proximity switch 17 at this time, under the signal transmission of the protection photoelectric sensor 12 and the lower proximity switch 17, the sheet conveying device will be controlled to stop conveying and start the protection function. And if the sheet 35 blocks the protection photoelectric sensor 12 and the corrugating mechanism of the corrugated tile press 6 is above the lower proximity switch 17 at this time (such as between the lower proximity switch 17 and the middle proximity switch 16, or between the upper proximity switch 15 and the middle proximity switch 16, or exactly at the upper proximity switch 15 and the middle proximity switch 16), then the sheet 35 is normally conveyed into the corrugated tile press 6;

[0057] Then, when the sheet 35 completely passes through the corrugating photoelectric sensor 14, the corrugating photoelectric sensor 14 transmits a signal to the corrugated tile press 6, and the corrugated tile press 6 starts to work. The corrugating mechanism on the corrugated tile press 6 corrugates the sheet 35;

[0058] Finally, when the corrugating mechanism after corrugating passes through the lower proximity switch 17 and the middle proximity switch 16 in sequence and returns to the upper proximity switch 15, the basic tiles are conveyed outwards and the corrugating mechanism is paused;

[0059] In this embodiment, as Figures 1 to 7As shown in the figure, a material sheet conveying device is provided with a material grabbing photoelectric sensor 13, which is located between the protective photoelectric sensor 12 and the profiling photoelectric sensor 14. The material grabbing photoelectric sensor 13 forms a material grabbing induction area on the material sheet conveying device. A servo material grabbing mechanism 18 is provided on the corrugated tile profiling machine 6 and is signal-connected to the material grabbing photoelectric sensor 13. Through the servo material grabbing mechanism 18, the material sheet 35 conveyed by the material sheet conveying device to the working position of the corrugated tile profiling machine 6 can be grabbed to the designated profiling position of the corrugated tile profiling machine 6, so as to perform profiling more precisely. The servo material grabbing mechanism 18 is driven by a servo motor, and electromagnetic structures are arranged side by side at the head of the servo material grabbing mechanism 18. The steel material sheet 35 can be grabbed and released through the electromagnetic structures. A positioning stop block is also provided in the mold of the corrugated tile profiling machine 6 to prevent the material sheet 35 from flying out. At the same time, a magnetic stop block is provided on the side of the corrugated tile profiling machine 6 to keep the material sheet 35 in the correct position at all times.

[0060] Further, in this embodiment, as Figures 1 to 7 shown, the corrugated tile profiling machine 6 is equipped with a hydraulic system 22 with a built-in cooling system 23. The hydraulic system 22 is used to drive the corrugated tile profiling machine 6 to work, and the cooling system 23 can ensure the stable operation of the hydraulic system 22 in high-temperature climates.

[0061] In this embodiment, as Figures 1 to 7 shown, the material sheet conveying device includes a first magnetic adsorption conveyor 4 and a second magnetic adsorption conveyor 5. The first magnetic adsorption conveyor 4 and the second magnetic adsorption conveyor 5 are sequentially arranged between the material sheet cutting machine 3 and the corrugated tile profiling machine 6. The feeding photoelectric sensor 11 is located on the first magnetic adsorption conveyor 4, and the protective photoelectric sensor 12 and the material grabbing photoelectric sensor 13 are arranged on the second magnetic adsorption conveyor 5. The material sheet conveying device adopts magnetic adsorption conveyors. The material sheet 35 can be flatly attached to the first magnetic adsorption conveyor 4 and the second magnetic adsorption conveyor 5 under magnetic adsorption, so as to ensure the flatness of the material sheet 35.

[0062] In this embodiment, as Figures 1 to 7 shown, the corrugated tile external conveying device includes a servo tile taking mechanism 19 and a discharging track 20 provided with a stacking trailer 21. The servo tile taking mechanism 19 is signal-connected to the corrugated tile profiling machine 6. The servo tile taking mechanism 19 is used to take out the basic tiles on the corrugated tile profiling machine 6 and send them to the stacking trailer 21. The servo tile taking mechanism 19 is composed of a support frame and a movable part. An electromagnetic tile taking structure is provided on the movable part, and different electromagnetic tile taking structures can be equipped according to different tile types. When the corrugated tile profiling machine 6 finishes profiling, it will transmit a signal to the servo tile taking mechanism 19. The servo motor controls the movable part of the servo tile taking mechanism 19, and the electromagnetic tile taking structure arranged on the movable part takes out the corrugated tiles and then places them on the stacking trailer 21. The stacking trailer 21 is conveyed out along the discharging track 20. Preferably, a plurality of stacking trailers 21 are provided on the discharging track 20.

[0063] Furthermore, in this embodiment, as Figures 1 to 7 shown, the servo tile taking mechanism 19 is provided with a counting photoelectric sensor 36. When the base tile disengages from the servo tile taking mechanism 19, the base tile falls onto the stacking trailer 21 through free fall. At the same time, the counting photoelectric sensor 36 detects whether the sheet 35 is pulled out of the base tile press 6 and completes the counting simultaneously. When the number of sheets 35 reaches the programmed count, the entire production line automatically pauses.

[0064] In this embodiment, as Figures 1 to 7 shown, the sheet cutting machine 3 is a trimming and cross-cutting integrated machine. The trimming and cross-cutting integrated machine can simultaneously cut the lace and cut the steel coil, directly forming the sheet 35 with lace. The trimming and cross-cutting integrated machine includes a frame 24. A cutting mechanism is provided on the frame 24. The cutting mechanism includes an upper tool holder 25, a lower tool holder 26, and a lifting mechanism. The upper tool holder 25 can be driven to lift by the lifting mechanism. An inlet space (the inlet space is the sheet processing area) can be formed between the upper tool holder 25 and the lower tool holder 26 during the rising process of the upper tool holder 25. A supporting roller 34 for supporting the sheet 35 is provided in the inlet space to ensure the flatness of the sheet 35. Preferably, the supporting roller 34 is provided on the lower tool holder 26. An upper lace cutter 27 is provided on the upper tool holder 25. A lower lace cutter 28 corresponding to the upper lace cutter 27 is provided on the lower tool holder 26. The upper lace cutter 27 and the lower lace cutter 28 cooperate with each other to cut the lace for the sheet 35 in the inlet space. An upper cross-cutting knife 29 is further provided on the upper tool holder 25. A lower cross-cutting knife 30 corresponding to the upper cross-cutting knife 29 is provided on the lower tool holder 26. The upper cross-cutting knife 29 and the lower cross-cutting knife 30 cooperate with each other to cut the sheet 35 transversely, cutting out the sheet 35 to be pressed with lace. The upper cross-cutting knife 29 and the lower cross-cutting knife 30 are located at the discharge end of the inlet space. Since both the upper lace cutter 27 and the upper cross-cutting knife 29 are provided on the upper tool holder 25, and both the lower lace cutter 28 and the lower cross-cutting knife 30 are provided on the lower tool holder 26, when the upper tool holder 25 and the lower tool holder 26 cooperate to cut the sheet 35, the sheet 35 can be trimmed and cut simultaneously, directly cutting out the sheet 35 with lace and meeting the pressing size. Using this trimming and cross-cutting integrated machine, one device can achieve the functions of a cross-cutting machine and a trimming machine, thereby reducing the floor area of the equipment, saving costs, and the trimming and cross-cutting methods are simple and easy to cooperate.

[0065] Furthermore, in this embodiment, as Figures 1 to 7 shown, the lower cross-cutting knife 30 and the upper cross-cutting knife 29 are arranged in a staggered manner along the conveying direction of the sheet 35, that is, the upper cross-cutting knife 29 is located behind the lower cross-cutting knife 30, and the upper cross-cutting knife 29 is closer to the discharge end of the inlet space. The staggered setting can prevent the upper cross-cutting knife 29 and the lower cross-cutting knife 30 from being damaged.

[0066] In this embodiment, as Figures 1 to 7As shown in the figure, a positioning baffle 32 is provided in the feeding space. The positioning baffle 32 is located on the opposite side of the lace knife. By relying on the positioning baffle 32, it can ensure the precise conveyance of the sheet 35 without swaying left and right, so as to precisely cut the lace without skewing. Preferably, the positioning baffle 32 is arranged on the side of the lower knife holder 26, and the lower lace knife 28 is arranged on the other side of the lower knife holder 26, that is, the positioning baffle 32 is arranged on the opposite side of the lower lace knife 28. When the sheet 35 enters between the upper knife holder 25 and the lower knife holder 26, one side of the sheet 35 will adhere to the plate surface of the positioning baffle 32, and then the other side is used to be cut by the upper lace knife 27 and the lower lace knife 28.

[0067] Further, in this embodiment, as Figures 1 to 7 shown, the upper lace knife 27 on the upper knife holder 25 and the lower lace knife 28 on the lower knife holder 26 are arranged in a staggered manner along the direction away from the positioning baffle 32. That is, the upper lace knife 27 is farther away from the positioning baffle 32. The lace of the lower lace knife 28 and the upper lace knife 27 also needs to be arranged in a staggered manner, so as to be able to cooperate to cut out the lace. As Figure 4 shown, the concave arc of the upper lace knife 27 faces the convex arc of the lower lace knife 28.

[0068] Further, in this embodiment, as Figures 1 to 7 shown, the end of the lower cross-cutting knife 30 is fixed on the blade body of the lower lace knife 28 and forms an L-shaped structure. Correspondingly, the end of the upper lace knife 27 is fixed on the blade body of the upper cross-cutting knife 29 and also forms an L-shaped structure.

[0069] In this embodiment, as Figures 1 to 7 shown, several guiding columns 31 are fixed on the lower knife holder 26, and the upper knife holder 25 is slidably connected to the guiding columns 31. The guiding columns 31 can guide the upper knife holder 25 to accurately lift and lower and cooperate with the lower knife holder 26, so as to avoid swaying during the lifting process and resulting in poor cutting.

[0070] Further, in this embodiment, as Figures 1 to 7 shown, the lifting mechanism includes a telescopic cylinder 33 fixed on the frame 24, and the telescopic rod of the telescopic cylinder 33 is fixedly connected to the upper knife holder 25. The telescopic cylinder 33 can drive the lifting of the upper knife holder 25.

[0071] In this embodiment, as Figures 1 to 7As shown in the figure, a temporary storage platform 8 is provided on the side of the unwinder 1 facing away from the fixed-length feeder 2. A temporary storage area is provided on the temporary storage platform 8. A feeding photoelectric sensor 10 is provided in the temporary storage area. The feeding photoelectric sensor 10 is signal-connected to the unwinder 1. A bridging roller 9 is provided between the feeding photoelectric sensor 10 and the unwinder 1. The steel coil on the unwinder 1 is temporarily stored on the temporary storage platform 8 through the bridging roller 9. When the feeding photoelectric sensor 10 detects that there is no steel coil on the temporary storage platform 8, the unwinder 1 will release the steel coil. The temporary storage platform 8 is arranged on the side of the unwinder 1 facing away from the fixed-length feeder 2. Compared with the temporary storage platform 8 being placed between the unwinder 1 and the fixed-length feeder 2, it will not cause the tension of the steel coil, thus affecting the feeding accuracy of the fixed-length feeder 2. Preferably, the unwinder 1 adopts a hydraulic unwinder, whose main power is controlled by a variable-frequency motor, and whether it feeds or not is controlled by the feeding photoelectric sensor 10. When the feeding photoelectric sensor 10 fails to sense the material, the PLC is used to control the variable-frequency motor to run at a certain linear speed, and the variable-frequency motor stops running after releasing a certain length of steel coil.

[0072] Further, in this embodiment, as Figures 1 to 7 shown, the distance between the fixed-length feeder 2 and the unwinder 1 is 3m to 5m. It not only saves the layout space but also takes into account the material buffer, enabling the production line to operate stably.

[0073] Further, in this embodiment, as Figures 1 to 7 shown, a hydraulic loading device 7 for lifting the steel coil is provided on one side of the core shaft of the unwinder 1. During loading, first, the steel coil is placed on the hydraulic loading device 7 by a crane, and then the hydraulic loading device 7 rises under the thrust of its hydraulic cylinder until the steel coil is lifted to the same height as the core shaft of the unwinder 1. Subsequently, the hydraulic loading device 7 holds the steel coil and travels to one side of the core shaft of the unwinder 1 driven by a reduction motor. After aligning the center of the steel coil with the core shaft of the unwinder 1, the core shaft of the unwinder 1 is inserted into the inner hole of the steel coil to receive the steel coil.

[0074] In this embodiment, a central control system for controlling the unwinder 1, the fixed-length feeder 2, the sheet cutter 3, the sheet conveying equipment, the corrugated tile press 6, and the corrugated tile external conveying equipment is included. The feeding photoelectric sensor 10, the feeding photoelectric sensor 11, the protection photoelectric sensor 12, the material grabbing photoelectric sensor 13, the pressing photoelectric sensor 14, and the counting photoelectric sensor 36 are all connected to the central control system. An optoelectronic alarm system can also be set on the central control system.

[0075] Specific examples are used in the invention to elaborate on the principle and implementation manner of the invention. The description of the above embodiments is only used to help understand the method and its core idea of the invention; at the same time, for those of ordinary skill in the art, according to the idea of the invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the invention.
