[0042] A roller coating device, comprising a machine 100, a loading device 200, a conveying device 300, a roller coating transfer device 400, a roller coating feeding device 500, and a discharge device 600, wherein the loading device 200 loads the product; the conveying device 300 conveys the product; the roller coating transfer device 400 receives the product conveyed by the conveying device 300; the roller coating feeding device 500 supplies ink of a predetermined thickness to the product in the roller coating transfer device 400; the discharge device 600 discharges the coated product; wherein a first transfer position 700 is provided between the loading device 200 and the conveying device 300, and the discharge device 600 A second transfer position 800 is provided between the device 600 and the transporting device 300, the transporting device 300 is located between the unloading position of the loading device 200 and the loading position of the unloading device 600, the rolling coating transfer device 400 is located at the transporting path of the transporting device 300, the transporting device 300 transports the uncoated products from the loading device 200 to the rolling coating transfer device 400, the rolling coating transfer device 400 drives the products to move to the rolling coating feeding device 500 for rolling coating, and the transporting device 300 transports the products that have been rolled on the rolling coating feeding device 500 to the loading position of the unloading device 600 for unloading.

[0043] See also Figures 1 to 3 As shown, the present application transports the product from the loading device 200 to the position of the roller coating feeding device 500 through the linkage of the transport device 300 and the roller coating transfer device 400, and as the roller coating transfer device 400 drives the product to move to the position of the roller coating feeding device 500, the ink is rolled on the product. After the rolling is completed, the coated product is transported to the loading position of the unloading device 600 again through the linkage of the transport device 300 and the roller coating transfer device 400, and the coated product is unloaded through the unloading device 600.

[0044] Specifically, the loading device 200 transports the product to the first intermediate transfer position 700, and then the transport device 300 transports the product at the first intermediate transfer position 700 to the loading position of the roller coating transfer device 400, and then the roller coating transfer device 400 drives the product to move to the roller coating feeding device 500, and the ink is applied to the product by the movement of the roller coating transfer device 400 and the roller coating feeding device 500, and then the transport device 300 transports the coated product on the roller coating transfer device 400 to the second intermediate transfer position 800, and then the unloading device 600 transports and unloads the product on the second intermediate transfer position 800. The above is the entire process of loading and unloading and rolling coating of the product. The specific detailed steps are explained in detail below and will not be repeated here.

[0045] Continue reading Figures 1 to 3As shown, in this embodiment, the structure of the loading device 200 is the same as that of the unloading device 600, but their functions are different. Specifically, the loading device 200 loads uncoated products, and the unloading device 600 unloads coated products, which is explained in detail below.

[0046] The loading device 200 includes a first conveying and handling structure 210 for loading products on a loading tray, and a second conveying and handling structure 220 for unloading empty trays. A first pallet handling mechanism 230 is provided between the first conveying and handling structure 210 and the second conveying and handling structure 220 to transport the empty pallet on the first conveying and handling structure 210 to the second conveying and handling structure 220. A loading and handling structure 240 for transporting products on the pallet is provided at the unloading end of the first conveying and handling structure 210. First tray separation structures 250 are provided on both sides of the first conveying and handling structure 210 and both sides of the second conveying and handling structure 220.

[0047] The unloading device 600 includes a third conveying and handling structure 610 for loading empty unloading pallets, and also includes a fourth conveying and handling structure 620 for unloading pallets loaded with rolled-coated products. A second pallet handling mechanism 630 is arranged between the third conveying and handling structure 610 and the fourth conveying and handling structure 620 to transport the empty pallets from the third conveying and handling structure 610 to the fourth conveying and handling structure 620. A unloading and handling structure 640 is arranged at the loading position of the fourth conveying and handling structure 620, and second pallet separation structures 650 are arranged on both sides of the third conveying and handling structure 610 and both sides of the fourth conveying and handling structure 620.

[0048] In the loading device 200, in the initial state, the products to be coated with ink are loaded in a tray, and multiple trays are stacked together and placed in the first conveying and handling structure 210. After the products in the tray are transported, the first tray handling mechanism 230 transports the empty tray to the second conveying and handling structure 220. The second conveying and handling structure 220 needs to stack and unload the empty trays remaining after the products are transported. In the unloading device 600, contrary to the loading device 200, the coated products need to be transported to the empty trays for stacking and unloading. Specifically, the third conveying and handling structure 610 loads the empty trays, and then the second tray handling mechanism 630 transports the empty trays from the third conveying and handling structure 610 to the fourth conveying and handling structure 620. Then the products are transported to the empty trays in the fourth conveying and handling structure 620, and the stacking and unloading of the coated products is gradually realized.

[0049] See also Figures 1 to 3As shown, in the present embodiment, the first conveying and handling structure 210, the second conveying and handling structure 220, the third conveying and handling structure 610 and the fourth conveying and handling structure 620 have the same structure and all play the role of conveying, lifting and handling. Specifically, the first conveying and handling structure 210 transfers the pallet loaded with stacked products to the loading position of the loading and handling structure 240. After the loading and handling structure 240 transports the products away, the top empty pallet is transported to the second conveying and handling structure 220 by the first pallet handling mechanism 230. The empty pallets are lifted and stacked by the second conveying and handling structure 220 to realize the unloading of the empty pallets. The transportation and loading of the products are completed through the above operations. Specifically, in order to prevent the lower pallet from being lifted up during the transportation of the empty pallet, the top pallet and the lower pallet are separated by the first tray separation structure 250.

[0050] Continue reading Figures 1 to 3 As shown, the third conveying and handling structure 610 transports the empty pallet to the loading position of the second pallet handling mechanism 630, and the empty pallet is transported to the fourth conveying and handling structure 620 through the second pallet handling mechanism 630. The unloading and handling structure 640 transports the coated product at the second transfer position 800 to the empty pallet at the fourth conveying and handling structure 620. The pallets with coated products are stacked and unloaded in this way, and the pallets are stacked and unloaded after a certain number of pallets are stacked.

[0051] Since the loading device 200 and the unloading device 600 have the same structure, the loading device 200 will be specifically described in the following description, and those skilled in the art can accurately obtain the detailed working principle and function of the unloading device 600 based on the specific structure and working process of the loading device 200.

[0052] The conveyor line 211 includes a conveyor line 211, a lifting module 212 is provided at the end of the conveyor line 211, a tooth fork 213 is fixedly installed at the lifting end of the lifting module 212, guide drive cylinders 215 are fixedly installed on both sides of the conveyor line 211, and the telescopic direction of each guide drive cylinder 215 is perpendicular to the conveying direction of the conveyor line 211, and a guide plate 214 is fixedly installed at the telescopic end of each guide drive cylinder 215.

[0053] See also Figures 4 to 6As shown, in the initial state, in order for the tooth fork 213 to lift and lower the pallet, the tooth fork 213 is located below the conveying plane of the conveyor line 211. First, the pallet loaded with products in the stacked state is transported to the position of the tooth fork 213 through the conveyor line 211, and the lifting module 212 drives the tooth fork 213 to lift, so that the pallet in the stacked state is supported by the tooth fork 213. As the lifting module 212 drives the tooth fork 213 to rise, the top product is lifted to the loading position of the loading and handling structure 240, and the loading and handling structure 240 lifts the top product After the products are moved away, the top empty pallet is transported to the second conveying and handling structure 220 by the first pallet handling mechanism 230 for stacking preparation, and then the lifting module 212 drives the tooth fork 213 to raise the height of a pallet, thereby providing new products for the loading position of the loading and handling structure 240. The above steps are repeated in a cycle until the products in the stacked pallets are completely transported away. After all the transportation is completed, the pallets with products in the new stacked state can be manually transported to the conveyor line 211 to provide new products for the loading and handling structure 240.

[0054] During the conveying process of the conveyor line 211, the guide plates 214 on both sides of the conveyor line 211 are used to guide and center the pallet, so that the pallet can be transported in the center. In order to adapt to the transportation of pallets or products of different widths, the guide plate 214 can be moved by the guide drive cylinder 215 to change the distance between the two guide plates 214, so that it can guide pallets of different widths.

[0055] Furthermore, the guide plate 214 is inclined and bent along the side of the conveying direction of the conveying line 211, so as to further realize the guiding function.

[0056] In this embodiment, the lifting module 212 can use a motor screw linear module, a linear motor module, a synchronous belt linear module or other structures that can achieve linear movement, and the specific structure and model are not limited here.

[0057] The first pallet transport mechanism 230 includes a first two-axis moving module 231 , a moving plate 232 is fixedly mounted on the moving end of the first two-axis moving module 231 , and clamping structures 233 for clamping are disposed at both ends of the moving plate 232 .

[0058] See also Figure 7 As shown, in order to realize the transportation of the empty pallet, the movable plate 232 is moved to the empty pallet position by the first two-axis movable module 231, and the empty pallet position is placed between the two clamping structures 233, and then the clamping structures 233 on both sides are started at the same time to clamp the empty pallet located therebetween. After clamping, the first two-axis movable module 231 transports the clamped empty pallet to the second conveying and handling structure 220, thereby completing the transportation of the empty pallet.

[0059] It should be noted here that the first two-axis movable module 231 can realize movement in both horizontal and vertical directions. Specifically, it can be composed of two motor screw modules, or two linear modules, or two synchronous belt modules, or a combination of the above two modules. The specific model is not limited here.

[0060] The clamping structure 233 includes a clamping cylinder 2331 fixedly mounted on the moving plate 232 , a transmission plate 2332 is mounted on the telescopic end of the clamping cylinder 2331 , and a clamping plate 2333 is also fixedly mounted on the transmission plate 2332 .

[0061] See also Figure 8 As shown, when clamping is required, the two clamping cylinders 2331 are started at the same time to drive the two clamping plates 2333 to move towards the pallet, thereby contacting the empty pallet to complete the clamping. In order to prevent the empty pallet from falling during the movement, a support plate (not marked in the figure) facing the direction of the empty pallet can be set on the bottom surface of the clamping plate 2333, and the empty pallet located above it can be supported by the support plate.

[0062] A scale 234 is disposed on the upper surface of the movable plate 232 along the clamping direction of the movable plate 232 .

[0063] See also Figure 8 As shown, in order to be able to clamp pallets of different widths, the positions of the two clamping structures 233 on the movable plate 232 can be adjusted. In order to accurately know the adjusted distance of the clamping structure 233, the ruler 234 can be used as a reference, that is, the adjusted distance can be intuitively observed through the scale on the ruler 234.

[0064] The loading and handling structure 240 includes a manipulator 241 , a lifting cylinder 242 is fixedly mounted on the moving end of the manipulator 241 , a fixing plate 243 is fixedly mounted on the telescopic end of the lifting cylinder 242 , and a plurality of first suction cups 244 are fixedly mounted on the fixing plate 243 .

[0065] See also Fig. 9 As shown, first, the first suction cup 244 is moved to the position of the first conveying and handling structure 210 by the robot 241, and the lifting cylinder 242 is started to drive the first suction cup 244 located on the fixed plate 243 to contact the product in the tray and adsorb the product. Next, the robot 241 and the lifting cylinder 242 work together to drive the product adsorbed by the first suction cup 244 to be transported to the first transfer position 700, so that the product is placed on the first transfer position 700 to complete the transportation.

[0066] The first disk dividing structure 250 includes a mounting frame 251 , on which a disk dividing cylinder 252 is fixedly mounted, and a disk dividing plate 253 is fixedly mounted at the telescopic end of the disk dividing cylinder 252 .

[0067] See also Fig.15 As shown, the bottom surface of the tray has a convex edge, so when two trays are stacked, there will be a certain gap between the two trays. The gap is the space formed by the convex edge and the upper surface of the tray. For details, see Fig.15 shown.

[0068] See also Fig.10 As shown, when the first pallet transporting mechanism 230 is carrying the top pallet, in order to prevent the top pallet from lifting the pallet below it, the first tray separating structure 250 is required to press the tray below to separate the two. Specifically, the tray separating plate 253 can be driven by the tray separating cylinder 252 to move to the gap between the top pallet and the tray below it, so that the top pallet can lift the tray below it; further, an inclined surface can be set on the end face of the tray separating plate 253 to make it easier to penetrate into the gap between the two pallets.

[0069] The transport device 300 includes a gantry 310, on which a second two-axis mobile module 320 for loading and a third two-axis mobile module 330 for unloading and transporting are respectively installed, and a plurality of second suction cups 340 are installed on the connecting plates of the mobile ends of the second two-axis mobile module 320 and the third two-axis mobile module 330.

[0070] See also Fig.11 As shown, when the product located on the first transfer position 700 needs to be transported to the roller-coating transfer device 400, the second suction cup 340 is first driven by the second two-axis movable module 320 to move to the first transfer position 700, and the second suction cup 340 adsorbs the product located on the first transfer position 700. After the adsorption is completed, the product adsorbed by the second suction cup 340 is transported to the roller-coating transfer device 400 through the second two-axis movable module 320, thereby completing the transportation of the uncoated product.

[0071] When the product is coated, the roller-coating transfer device 400 transports the coated product to the unloading position, and then the third two-axis movable module 330 drives the second suction cup 340 connected thereto to move to the unloading position of the roller-coating transfer device 400, and the second suction cup 340 adsorbs the coated product on the roller-coating transfer device 400, and the transport device 300 drives the second suction cup 340 to transport the coated product to the second transfer position 800, waiting for the unloading device 600 to transport and unload the coated product at the second transfer position 800.

[0072] In this embodiment, the second two-axis moving module 320 and the third two-axis moving module 330 can select a motor screw module, a synchronous belt module, a linear motor module, etc., and the specific type and model are not limited here.

[0073] It should be noted here that the loading position and the unloading position of the roller coating transfer device 400 are at the same position.

[0074] Specifically, in this embodiment, the second two-axis mobile module 320 and the third two-axis mobile module 330 can both realize lateral and vertical movement. Specifically, a motor screw module, a synchronous belt module, a linear motor module, a cylinder, etc. can be combined to realize two-axis movement. The specific combination types will not be elaborated in detail here.

[0075] The roller coating transfer device 400 includes a fourth two-axis movable module 410, a first rotating drive member 420 is installed at the movable end of the fourth two-axis movable module 410, a second rotating drive member 430 for horizontal rotation is fixedly installed at the rotating end of the first rotating drive member 420, and an adsorption carrier 440 is fixedly installed at the rotating end of the second rotating drive member 430.

[0076] See also Fig.12 As shown, when the roller coating transfer device 400 transports the uncoated product from the transport device 300, the first rotating drive member 420 first drives the second rotating drive member 430 to rotate so that the roller coating transfer device 400 is horizontal, and then the fourth two-axis movable module 410 moves the adsorption carrier 440 to the unloading position of the second two-axis movable module 320. At this time, the adsorption carrier 440 can be driven to rotate by the second rotating drive member 430 to adapt to the position of the product adsorbed by the second suction cup 340 on the second two-axis movable module 320. With the linkage between the second two-axis movable module 320 and the fourth two-axis movable module 410, the uncoated product is transported to the adsorption carrier 440. Next, the linkage of the fourth two-axis movable module 410, the first rotating drive member 420 and the second rotating drive member 430 transfers the product on the adsorption carrier 440 to the position of the roller coating feeding device 500, thereby cooperating with the roller coating feeding device 500 to realize rolling coating of the product on the adsorption carrier 440.

[0077] It should be noted here that the first rotating drive member 420 can drive the adsorption carrier 440 to rotate in the vertical direction, and the linkage between the first rotating drive member 420 and the second rotating drive member 430 can drive the product on the adsorption carrier 440 to different angles. In the present embodiment, the side of the product is mainly coated, that is, the product on the adsorption carrier 440 is moved toward the coating position of the roller coating feeding device 500 through the linkage between the first rotating drive member 420 and the second rotating drive member 430.

[0078] The fourth two-axis moving module 410 can realize movement in both horizontal and vertical directions, and can be composed of a combination of components that can realize linear motion, such as a motor screw linear module, a motor synchronous belt linear module, a linear motor module, and a cylinder, that is, it can realize two-axis movement.

[0079] In this embodiment, the first rotation driving member 420 is a motor, and the second rotation driving member 430 is a DD motor.

[0080] The roller coating feeding device 500 includes a mounting plate 510, on which a roller 511 is rotatably mounted, and a rotating drive motor 512 is fixedly mounted on the mounting plate 510 for driving the roller 511 to rotate, an ink cartridge 513 is mounted on the mounting plate 510, the ink cartridge 513 is located below the roller 511, and the roller 511 is at least partially located in the ink cartridge 513, a scraper 514 is arranged on one side of the roller 511, and an adjusting slide 515 is also mounted on the mounting plate 510 for driving the scraper 514 to move toward or away from the roller 511.

[0081] See also Fig.13 and Fig.14 As shown, in order to enable the ink coated on the product to reach a predetermined thickness, the thickness can be controlled by adjusting the distance between the slide 515 and the scraper 514 to approach or move away from the roller 511. Specifically, the ink cartridge 513 stores ink. Since part of the roller 511 is located in the ink cartridge 513, the outer surface of the roller 511 will have ink. The rotary drive motor 512 drives the roller 511 to rotate, so that the entire outer surface of the roller 511 can be filled with ink. As the roller 511 rotates, the scraper 514 scrapes off excess ink on the outer surface of the roller 511, so that the thickness of the ink on the roller 511 is a predetermined thickness, which facilitates the rolling transfer of the ink to the product on the adsorption carrier 440.

[0082] The roller coating feeding device 500 also includes a linear module 516, and the linear module 516, the moving end of which is fixedly installed with a moving frame 517, the mounting plate 510 is rotatably installed on the moving frame 517, a tension spring 518 is hung between the mounting plate 510 and the moving frame 517, the tension spring 518 and the roller 511 are respectively located on both sides of the rotating axis of the mounting plate 510, a tension sensor 519 is also arranged between the tension spring 518 and the moving frame 517, a counterweight block 520 is installed on the end of the mounting plate 510 away from the roller 511, and a positioning camera 521 is also arranged on one side of the linear module 516.

[0083] See also Fig.13 and Fig.14As shown, since the mounting plate 510 is rotatably mounted on the mobile frame 517, in order to prevent the end of the roller 511 from falling, a counterweight block 520 and a downward pulling spring 518 can be set at the end away from the roller 511, that is, the gravity of the counterweight block 520, the tension of the tension spring 518 and the end where the roller 511 is located are balanced, and further, it can also prevent the product on the roller transfer device 400 from having a hard collision with the roller 511 when rolling, thereby achieving the effect of protecting the product; in order to be able to accurately control the product As for the force in contact with the roller 511, a tension sensor 519 is provided between the tension spring 518 and the movable frame 517. When the product on the roller coating transfer device 400 presses down the roller 511 for roller coating transfer, the tension spring 518 at the other end will rise and will also pull the tension spring 518, so as to detect the amount of force acting on the roller 511 at this time, so as to keep the force acting on the roller 511 within a certain range, so as to prevent the product from being damaged due to excessive force or the ink from being unable to be rolled and transferred due to insufficient force.

[0084] During the rolling process, in order to make the rolling process more accurate, in this embodiment, the product position is photographed and positioned in combination with the positioning camera 521. The photographing and positioning part is a prior art and is not limited here.
