TECHNICAL FIELD

[0001] The present application relates to the technical field of plate processing, in particular to a turnover machine of a plate processing assembly line and a board turnover process. BACKGROUND

[0002] As a basic material in the field of building decoration and structure, plates are various, including wooden plates, metal plates, composite plates and ceramic plates. Among them, foamed ceramic plate, as a new type of green building material, has excellent performance such as light weight, fireproof, heat insulation and durability, and is widely used in the field of building decoration. In the process of processing foamed ceramic plate into decorative lines, it is often necessary to turn over the cut rectangular board to change its state from lying to standing, so as to carry out subsequent processing such as beveling and polishing. The traditional board turnover is mostly completed by manual or simple machine, which has the following problems: 1. The board is easy to be damaged: the corners of the board are easy to be bumped and broken in the turnover process, resulting in material waste and low yield; 2. Poor positioning accuracy: manual turnover cannot guarantee the consistency of the board posture, affecting the alignment and accuracy of subsequent processing; 3. Low automation level: the traditional turnover method cannot realize automatic connection with the previous and subsequent processes, which restricts the overall efficiency and integration level of the production line.

[0004] To achieve the above purpose, the present application realizes the following technical scheme: a turnover machine of a plate processing assembly line, comprising: a multi-section conveying assembly, comprising at least three spaced conveying belts, and a gap is formed between adjacent conveying belts; a turnover assembly, comprising at least two rotating rods, one end of each rotating rod respectively extends into the gap, and the other end is fixedly connected with a rotating shaft, and the rotating shaft is driven by a forward and reverse motor; a transfer assembly, provided at the output end of the multi-section conveying assembly, comprising a transfer frame and a plurality of transfer rollers arranged side by side, for receiving the board turned over by the turnover assembly.

[0005] Further, the multi-section conveying assembly comprises a conveying frame, a driving shaft, a first driven shaft, a second driven shaft and a third driven shaft; the driving shaft is driven by a driving motor and connected with the first driven shaft, the second driven shaft and the third driven shaft through the first conveying belt, the second conveying belt and the third conveying belt respectively; a first gap is formed between the first conveying belt and the second conveying belt, and a second gap is formed between the second conveying belt and the third conveying belt.

[0006] Further, the turnover assembly comprises a first rotating rod and a second rotating rod; the first end of the first rotating rod extends into the first gap, and the first end of the second rotating rod extends into the second gap; the second ends of the first rotating rod and the second rotating rod are fixed on the same rotating shaft and synchronously rotate under the driving of the forward-reverse rotating motor.

[0007] Further, the top surface of the first rotating rod and the second rotating rod is not higher than the conveying surface of the conveying belt in the non-working state.

[0008] Further, the side of the first rotating rod away from the second rotating rod is provided with a first abutting component, and the side of the second rotating rod away from the first rotating rod is provided with a second abutting component.

[0009] Further, the first abutting component comprises a first fine adjustment screw rod, a first screw rod seat for mounting the first fine adjustment screw rod, and a first lifting motor for driving the first screw rod seat to lift, and the second abutting component comprises a second fine adjustment screw rod, a second screw rod seat for mounting the second fine adjustment screw rod, and a second lifting motor for driving the second screw rod seat to lift.

[0010] Further, the transfer frame comprises a first frame body and a second frame body arranged side by side, one end of the transfer roller away from the turnover assembly is mounted on the top of the first frame body through a first bearing member and on the top of the second frame body through a second bearing member, the transfer roller is fixed with a sprocket between the first bearing member and the second bearing member, and the sprockets of a plurality of transfer rollers are connected together through a chain to synchronously rotate.

[0011] Further, the transfer frame roller is a polyurethane roller.

[0012] On the other hand, the turnover process of the turnover machine for the board strip comprises the following steps: S1: conveying the board strip to a preset position through the multi-section conveying assembly; S2: controlling the rotating rod of the turnover assembly to rise from the gap of the conveying belt and hold the board strip; S3: driving the rotating rod to rotate by 90° under the driving of the forward-reverse rotating motor, turning over the board strip and placing it on the transfer assembly; S4: conveying the turned-over board strip to the next process by the transfer assembly.

[0013] Further, the board strip is a rectangular board strip of foamed material, and the long edge of the end surface thereof is turned from horizontal to vertical after being turned over.

[0014] The turnover machine for the board processing flow line and the turnover process of the board strip of the present application have the following beneficial effects: 1. The flipping machine integrates flipping and transfer operations into one unit. It not only completes the crucial posture transformation of rectangular strips from "lying flat" (long side horizontal) to "standing upright" (long side vertical), significantly increasing the effective height for subsequent processing, but also removes the flipped rectangular strips from the current workstation and transports them to the next process, greatly simplifying the process and improving space utilization and production efficiency. The multi-segment conveying assembly forms the physical space (first gap, second gap) for the flipping mechanism (rotating rod). It can stably convey the blank / strip during cutting and provide execution space for the subsequent flipping process. It is a key transitional device connecting the longitudinal cutting and flipping processes, achieving seamless connection between processes. The flipping assembly utilizes the two gaps formed by the multi-segment conveying assembly, allowing the rotating rod to be hidden under the conveying surface when not in operation; during operation, it rises, using the bottom of the strip as a fulcrum, and achieves a smooth 90° flip using two-point support. The structure is simple, the action is precise, and the impact on the rectangular strips is minimal. The transfer assembly forms a transition platform that receives the flipped rectangular strips and continues to transport them forward. Its structure is simple and reliable. Through multiple synchronously rotating transfer rollers, it can not only smoothly receive the rectangular strips, but also transport them to the slant cutting machine in the correct direction, ensuring the smooth connection of the processes.

[0015] 2. The slat flipping process uses a multi-segment conveying component, flipping component, and transfer component to achieve automatic 90° flipping and transfer of slats, replacing manual operation and greatly improving flipping efficiency and safety; the flipping process is stable and precise, effectively avoiding damage to the edges and corners of rectangular slats and improving the yield; the overall structure is seamlessly connected with the preceding and following processes, supports continuous and automated production, and is suitable for reliable flipping of slats of different specifications.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] Please refer to the drawings in the specification of the present application Figure 1 , which shows a state change diagram of processing a slab into a board strip. The size of the slab 101 is 240cm*120cm*12cm, and after longitudinal cutting, a rectangular board strip 102 with a size of 16cm*120cm*12cm is obtained. After oblique cutting, a triangular board strip 103 with a cross section of three edges of 16cm*12cm*20cm is obtained. Finally, the oblique edge of 20cm is polished to process a board strip 104 with a specific shape. Preferably, in the present application, the slab 101 is a foamed ceramic slab 101. Embodiment 1

[0041] As shown in the drawings Figures 6-10 , the present embodiment provides a turnover machine 4 of a plate processing flow line, which comprises a multi-section conveying assembly 9, a turnover assembly 41 for turning over the rectangular board strip 102 by 90° so that the end face long edge of the rectangular board strip 102 faces upward, and a transfer assembly 42 for receiving and transferring the board strip. The multi-section conveying assembly 9 is arranged below the longitudinal cutting machine 3 and comprises at least three conveying belts arranged at intervals, and gaps are formed between adjacent conveying belts. The turnover assembly 41 comprises at least two rotating rods, one end of each rotating rod respectively extends into the gap, and the other end is fixedly connected with a rotating main shaft, and the rotating main shaft is driven by a forward and reverse rotating motor. The transfer assembly 42 is arranged at the output end of the multi-section conveying assembly 9 and comprises a transfer frame 421 and a plurality of transfer rollers 422 arranged side by side, which are used to receive the rectangular board strip 102 turned over by the turnover assembly 41. The turnover machine 4 integrates the two actions of turnover and transfer, not only completes the key posture conversion of changing the rectangular board strip 102 from “lying flat” (long edge horizontal) to “standing straight” (long edge vertical), thereby significantly increasing the effective height during subsequent processing, but also is responsible for moving the turned-over rectangular board strip 102 out of the current station and conveying it to the next process, greatly simplifying the process, improving the space utilization and production efficiency.

[0042] As attached Figure 7 As shown, the multi-segment conveying assembly 9 includes a conveyor frame 91, a drive shaft 92, a first driven shaft 93, a second driven shaft 94, and a third driven shaft 95. The drive shaft 92 is located at the front end of the conveyor frame 91 and is driven by a drive motor. The first driven shaft 93, the second driven shaft 94, and the third driven shaft 95 are located at the rear end of the conveyor frame 91. The drive motor and the drive shaft 92 are mounted on the conveyor frame 91. The first driven shaft 93 is connected to the drive shaft 92 via a first conveyor belt, the second driven shaft 94 is connected to the drive shaft 92 via a second conveyor belt, and the third driven shaft 95 is connected to the drive shaft 92 via a third conveyor belt. The first conveyor belt, the second conveyor belt, and the third conveyor belt are spaced apart to form a first gap 96 between the first driven shaft 93 and the second driven shaft 94, and a second gap 97 between the third driven shaft 95 and the second driven shaft 94. The core design of the multi-segment conveyor assembly 9 lies in the physical space (first gap 96, second gap 97) formed for the interleaving and flipping mechanism (rotating rod). It not only stably conveys the slab / strip during cutting but also provides execution space for the subsequent flipping process. It is a crucial transitional device connecting the longitudinal cutting and flipping processes, achieving seamless integration between them. The conveyor frame 91, drive shaft 92, three driven shafts, and three conveyor belts constitute three independent narrow-width conveyor belt structures, jointly supporting and conveying the slab. The first gap 96 and second gap 97 reserve space, allowing the flipping assembly 41 (rotating rod) of the flipping machine 4 to rise from below, lifting and flipping the slab, which is a key structure for coordinated operation.

[0043] As attached Figure 8As shown, the turnover assembly 41 includes a first rotating rod 411, a second rotating rod 412, a rotating shaft 413, and a forward-reverse rotating motor 414. The first rotating rod 411 and the second rotating rod 412 serve as the execution arm, and the rotating shaft 413 and the forward-reverse rotating motor 414 provide synchronous and fixed-angle (90° forward rotation or reverse rotation back to position) rotation power for the two rotating rods. The first end of the first rotating rod 411 extends into the first gap 96, and the first end of the second rotating rod 412 extends into the second gap 97. The second ends of the first rotating rod 411 and the second rotating rod 412 are fixed to the same rotating shaft 413 and are driven to rotate synchronously by the forward-reverse rotating motor 414. The top surfaces of the first rotating rod 411 and the second rotating rod 412 are not higher than the conveying surface of the conveying belt in the non-working state, which can avoid interfering with the conveying of the rectangular slats 102. The turnover assembly 41 is a clever, reliable, and non-interfering normal conveying turnover structure. The two gaps formed by the multi-section conveying assembly 9 enable the rotating rods to hide under the conveying surface in the non-working state. When working, the rotating rods are lifted up, and the bottom of the slat serves as a fulcrum to achieve stable 90° turnover by two-point lifting. The structure is simple, the action is accurate, and the impact on the rectangular slats 102 is small. In order to avoid cutting the conveying belt, a connection part with a thickness of less than 0.5 mm will be reserved between the cut rectangular slats 102 and the bottom of the rectangular slats 102. Due to the material properties of the foamed ceramic, this extremely small thickness of the connection part will be torn off during turnover.

[0044] As shown in the accompanying drawings, Figures 8-9 The side of the first rotating rod 411 away from the second rotating rod 412 is provided with a first abutting component 43 for abutting against the slat during cutting, and the side of the second rotating rod 412 away from the first rotating rod 411 is provided with a second abutting component 44 for abutting against the slat during cutting. The first abutting component 43 includes a first fine adjustment screw 431, a first screw seat 432 mounting the first fine adjustment screw 431, and a first lifting motor 433 driving the first screw seat 432 to lift. The second abutting component 44 includes a second fine adjustment screw, a second screw seat mounting the second fine adjustment screw, and a second lifting motor driving the second screw seat to lift. The first abutting component 43 and the second abutting component 44 play a positioning role in the longitudinal cutting process. Before cutting, the fine adjustment screw is lifted to abut against the front end of the slab, which is in opposition to the conveying power at the rear end, ensuring the absolute stillness of the slab at the moment of cutting, thereby ensuring the accuracy of the cutting size and the quality of the cut. The fine adjustment design of the fine adjustment screw can adapt to the positioning needs of rectangular slats 102 of different specifications. The lifting motor drives the screw seat and the fine adjustment screw to make vertical motion, realizing the action of abutting against and loosening.

[0045] As shown in the accompanying drawings, Figure 10As shown, the transfer assembly 42 includes a transfer frame 421 and a plurality of transfer rollers 422 arranged side by side; one end of the transfer rollers 422 is mounted on the transfer frame 421, and the other end is arranged towards the turnover assembly 41. The transfer frame 421 includes a first frame body 4211 and a second frame body 4212 arranged side by side, and the end of the transfer rollers 422 away from the turnover assembly 41 is mounted on the top of the first frame body 4211 through a first bearing 423 and on the top of the second frame body 4212 through a second bearing 424. A sprocket is fixed between the first bearing 423 and the second bearing 424 of the transfer roller 422, and the sprockets of the plurality of transfer rollers 422 are connected together by a chain and can be synchronously rotated by a motor drive. The transfer assembly 42 constitutes a transition platform for receiving the rectangular slats 102 after turnover and continuing to transport forward, which has a simple and reliable structure. Through the plurality of synchronously rotating transfer rollers 422, the rectangular slats 102 can be smoothly received and transported in the correct direction to the bevel cutting machine 5, ensuring the smoothness of process connection. The second frame body 4212 is provided with a baffle 45 to prevent the rectangular slats 102 from falling. Preferably, the transfer roller 422 is a polyurethane roller, which is relatively soft and can effectively avoid scratching the surface of the rectangular slat 102.

[0046] The slat turnover process of the turnover machine 4 of the present embodiment includes the following steps: S1: conveying the slats to a predetermined position through the multi-section conveying assembly 9; S2: controlling the rotation rod of the turnover assembly 41 to rise from the gap between the conveying belts and lift the slats; S3: driving the rotation rod to rotate 90° by the forward and reverse rotation motor 414, turning over the slats and placing them on the transfer assembly 42; after turnover, the end face long side of the slats changes from horizontal to vertical; S4: conveying the turned over slats to the next process by the transfer assembly 42.

[0047] The slat turnover process realizes 90° automatic turnover and transfer of the slats through the cooperation of the multi-section conveying assembly 9, the turnover assembly 41 and the transfer assembly 42, replaces manual operation, greatly improves turnover efficiency and safety; the turnover process is stable and accurate, effectively avoids damage to the corners of the rectangular slats 102, and improves the yield; the overall structure seamlessly connects with the previous and subsequent processes, supports continuous and automated production, and is suitable for reliable turnover of slats of different specifications.

The design of the outward expansion plate 54 reduces the difficulty of the strip entering the guide rail 53, and improves the smoothness of the feeding. Figure 12As shown, the shunting conveyor 6 sequentially comprises a first shunting mechanism 61 separating two triangular slats 103 and a second shunting mechanism 62 conveying the two triangular slats 103 apart. The shunting conveyor 6 provides an efficient and gradual triangular slat 103 separation scheme. The closely fitted triangular slats 103 are initially separated by air force (the first shunting mechanism 61), and then smoothly guided to different conveying paths or subsequent equipment by the gradually changing mechanical guide (the second shunting mechanism 62), avoiding rigid scraping or hard pulling throughout the process, effectively protecting the corners and cutting surfaces of the brittle ceramic slats. The first shunting mechanism 61 comprises a first shunting conveying assembly 611 and a blower 612 arranged above the first shunting conveying assembly 611; the first shunting conveying assembly 611 comprises a shunting support 6111, a plurality of rotating rollers 6112 arranged side by side on the shunting support 6111, and a plurality of buffer rods 6113 arranged on both sides of the shunting support 6111, the buffer rods 6113 being arranged obliquely downward from the side edges of the shunting support 6111 to the middle part of the shunting support 6111, and the ends of the buffer rods 6113 being provided with elastic buffer heads 6114. The blower 612 of the first shunting mechanism 61 uses air flow to penetrate from the fitting seam, generating a separation force to achieve the initial flexible separation of the two triangular slats 103. The buffer rods 6113 and the elastic buffer heads 6114 can prevent the triangular slats 103 from deviating excessively or colliding with the support during conveying, serving as protection and limiting. The second shunting mechanism 62 comprises a second shunting conveying assembly 621 and a plurality of guide plate assemblies 622 sequentially arranged on the second shunting conveying assembly 621; the second shunting conveying assembly 621 is a belt type conveying assembly, and the guide plate assembly 622 comprises a first vertical rod 6221, a horizontal rod 6222, and a second vertical rod 6223; the first vertical rod 6221 and the second vertical rod 6223 are arranged on both sides of the second shunting conveying assembly 621, respectively, the horizontal rod 6222 is connected to the first vertical rod 6221 and the second vertical rod 6223 at both ends, respectively, the middle part of the horizontal rod 6222 is provided with a hanging piece 6224, and the bottom end of the hanging piece 6224 is provided with two guide plates 6225 arranged in an eight-shaped manner; the guide plates 6225 of a plurality of guide plate assemblies 622 are arranged in a horn shape in sequence from front to back. The second shunting mechanism 62 gradually and smoothly guides the two triangular slats 103 to both sides through the horn-shaped channel formed by a series of eight-shaped guide plates 6225, completing the complete shunting in space.

[0056] As shown in the accompanying drawings, Figure 2 The line grinder 7 is a four-head double-sided line grinder 7, which can simultaneously grind the bevel edges of two triangular slats 103, and a plurality of grinding heads perform different processes such as rough grinding and fine grinding, improving the grinding efficiency and processing precision of the modeling surface of the triangular slat 103, and ensuring the appearance quality of the final product.

[0057] The working principle of the slat processing assembly line 200 in this embodiment is as follows: The upper plate machine 2 first sucks the plate blank 101 to the roller conveying assembly 8, the roller conveying assembly 8 conveys the plate blank 101 to the multi-section conveying assembly 9; the fine adjustment screw of the first and second top pressing assemblies 43 and 44 rises to press against the front end of the plate blank 101; the cutting unit 33 of the longitudinal cutting machine 3 descends and cuts the plate blank 101 into rectangular slats 102 along the width direction, at this time, the two long edges (L1 and L2) of the end face of the rectangular slat 102 are distributed up and down, and the two short edges (S1 and S2) are distributed left and right; the fine adjustment screw of the first and second top pressing assemblies 43 and 44 descends, the forward and reverse rotation motor 414 of the turnover assembly 41 controls the two rotating rods to rotate forward, and the two rotating rods lift the rectangular slat 102 from the bottom to turn it by 90° to the transfer roller 422 of the transfer assembly 42, at this time, the two long edges (L1 and L2) of the end face of the rectangular slat 102 are distributed left and right, and the two short edges (S1 and S2) are distributed up and down; the transfer assembly 42 sends the rectangular slat 102 to the bevel cutting conveying assembly 51, the bevel cutting assembly 52 cuts the rectangular slat 102 into two triangular slats 103 with triangular end faces along the length direction of the rectangular slat 102; the bevel cutting conveying assembly 51 conveys the two triangular slats 103 still in the up-and-down adhering state to the first shunt conveying assembly 611 of the first shunt mechanism 61, and controls the air blower 612 to blow downward to separate the two triangular slats 103; the two triangular slats 103 continue to move forward to the second shunt conveying assembly 621 of the second shunt mechanism 62, the guide plate assembly 622 separates and sends the two triangular slats 103 into the line slat grinder 7; the line slat grinder 7 grinds the triangular slat 103 into a finished slat 104 of a required shape.

[0058] The slat processing line 200 of the embodiment realizes the full-process automatic and continuous production of the slat 104 through the cooperation of the plate feeder 1, the upper plate machine 2, the longitudinal cutting machine 3, the turnover machine 4, the bevel cutting machine 5, the shunt conveying machine 6 and the line slat grinder 7. The overall technical effect is remarkable: it realizes the production of large-height products from small-thickness plate blanks, reduces the requirement for the thickness of the original plate blank through the unique turnover design of the turnover machine 4, makes the production easier to carry out; it replaces manual work with automation, seamlessly connects each process, eliminates the waiting and handling time in the traditional mode, can realize 24-hour continuous operation, and further greatly improves the production efficiency and capacity; and through mechanical positioning, synchronous conveying, accurate cutting and grinding, the size precision and quality of the finished product are ensured.
