Description

Technical Field

[0001] This application relates to the technical field of transport rack cleaning, and particularly to a transport rack cleaning system and a cleaning method. Background Art

[0002] In the production process of fiberglass products, transport racks are often used as transport tools for fiberglass products. The transport racks carry fiberglass products and are transported between various processes in the production factory and downstream factories. The transport racks are made of iron, generally including lower legs and upper legs. The four lower legs are on the ground, facilitating forklift handling, and the four upper legs can be rotated and folded for storage, facilitating storage.

[0003] In order not to contaminate the transported fiberglass products, it is necessary to regularly clean the transport racks to keep them clean. Currently, the transport racks are cleaned by manual handling. However, the weight of the transport racks often exceeds 50 Kg. When manually cleaning, it is necessary to frequently move and unfold the folded transport iron racks. The labor intensity of the operators is high, the cleaning process is inefficient, and there are safety hazards. Summary of the Invention

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0050] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0051] The present application provides a transport rack cleaning system and a cleaning method. The transport rack cleaning system is used to clean the transport rack for transporting fiberglass products. The transport rack cleaning system sequentially includes, in the transport direction of the transport rack to be cleaned: an on-line tooling pallet lifting mechanism, a feeding mechanism, a disassembly and extraction mechanism, a unfolding mechanism, and a cleaning mechanism. The on-line tooling pallet lifting mechanism is configured to lift the tooling pallet to a first preset height and convey it above the feeding mechanism. The feeding mechanism is configured to place the stacked transport racks to be cleaned on the tooling pallet when the tooling pallet is above the feeding mechanism, and convey the transport racks to the disassembly and extraction mechanism. The disassembly and extraction mechanism is configured to lift the second-layer stacked transport rack to be cleaned from bottom to top, so that there is one remaining transport rack to be cleaned on the tooling pallet, convey the remaining transport racks to be cleaned to the unfolding mechanism, and when waiting for the next tooling pallet to be conveyed to the disassembly and extraction mechanism, place the lifted transport rack to be cleaned on the next tooling pallet. The unfolding mechanism is configured to unfold the remaining one transport rack to be cleaned. The cleaning mechanism is configured to clean the unfolded transport rack to be cleaned.

[0052] The transport rack cleaning system of the present application realizes the full automation of the feeding, multi-layer disassembly and extraction, unfolding, and cleaning of the transport rack by setting corresponding mechanisms, reduces the labor intensity of operators, improves the cleaning efficiency, and avoids potential safety hazards.

[0053] As Figure 3 shown, during the production process of fiberglass products, the transport rack 990 shown in the figure is often used as a transport tooling for fiberglass products. The transport rack 990 carries fiberglass products and is transported between various processes of the manufacturer and downstream factories. The transport rack 990 includes: four upper legs 991, four lower legs 992, longitudinal beams 993, and cross beams 994. Among them, the upper legs 991 can be rotated and folded to a horizontal state to form the folded transport rack 990, and the lower legs 992 adopt a hollow tubular structure. The transport forklift forks the transport rack 990 by inserting into the longitudinal beam 993 or the cross beam 994 around the transport rack 990.

[0054] According to an exemplary embodiment, as Figures 1 - 2 shown, in the first aspect of the present application, a transport rack cleaning system is provided. The transport rack cleaning system is used to clean the transport rack 990 for transporting fiberglass products. The transport rack cleaning system sequentially includes, in the transport direction of the transport rack 990 to be cleaned: an on-line tooling pallet lifting mechanism 100, a feeding mechanism 200, a disassembly and extraction mechanism 300, a unfolding mechanism 400, a cleaning mechanism 500, a folding mechanism 600, a stacking mechanism 700, a off-line mechanism 800, and an off-line tooling pallet lifting mechanism 900.

[0055] In this embodiment, the loading mechanism 200, the removing and picking mechanism 300, the unfolding mechanism 400, the cleaning mechanism 500, the folding mechanism 600, the stacking mechanism 700, and the offline mechanism 800 all have a double-layer conveying unit 190. By setting the double-layer conveying unit 190, after the tooling pallet 980 completes the transportation of the transport rack 990 from the upper-layer conveying unit, it can return to the initial mechanism of the system by the lower-layer conveying unit, facilitating the next transportation and solving the problem of the online recycling and circulation of the tooling pallet 980. The upper layer of the double-layer conveying unit 190 is responsible for the movement and transportation of the tooling pallet 980 and the transport rack 990 carried thereon between various mechanisms, and the lower layer of the double-layer conveying unit 190 is responsible for returning the empty tooling pallet 980. Both the upper and lower layers of the double-layer conveying unit 190 adopt a chain conveying method, which can reduce the wear on the tooling pallet 980 and avoid the problem that the roller method is prone to winding long fibers. The upper and lower layer conveying units respectively have drive motors and start-stop functions, which are convenient for separate control.

[0056] As Figure 1 shown, the online tooling pallet lifting mechanism 100 is a single-layer conveying unit. The online tooling pallet lifting mechanism 100 includes an online lifting component 110. The single-layer conveying unit realizes lifting under the drive of the online lifting component 110. The single-layer conveying unit of the online tooling pallet lifting mechanism 100 raises the received empty tooling pallet 980 to the first preset height, that is, the upper layer position, and conveys the tooling pallet 980 above the loading mechanism 200.

[0057] As Figure 1 shown, in the loading mechanism 200, the loading mechanism 200 receives the stacked transport racks 990 to be cleaned transported by a forklift. When the tooling pallet 980 is above the loading mechanism 200, the loading mechanism 200 places the stacked transport racks 990 to be cleaned on the tooling pallet 980. The loading mechanism 200 can be provided with a guiding device to facilitate the forklift to smoothly place the transport rack 990 on the tooling pallet 980, and at the same time, a limit protection railing can be provided to prevent the forklift from hitting.

[0058] As Figure 4 shown, the tooling pallet 980 includes a pallet frame 981 and a positioning pin 982. The frame 981 adopts a square tube frame structure, and its flat bottom surface is convenient for moving between various mechanisms. The positioning pin 982 is fixedly connected to the pallet frame 981. The positioning pin 982 is used for plugging and connecting with the lower leg 992 of the transport rack 990 so that the transport rack 990 is placed on the tooling pallet 980, and under the movement of the tooling pallet 980, the transport rack 990 is conveyed. By setting the tooling pallet 980 as the conveying carrier of the transport rack 990 and forming a stable structure with the transport rack 990, the stable conveying of the transport rack 990 in the system is realized.

[0059] As Figure 1As shown, the tooling tray 980 transports the transport rack 990 to the disassembling and removing mechanism 300. The upper conveying unit of the disassembling and removing mechanism 300 starts and stops conveying. The disassembling and removing mechanism 300 lifts the second-layer stacked transport racks 990 to be cleaned from bottom to top, so that only one transport rack 990 to be cleaned remains on the tooling tray 980. Then the upper conveying unit starts conveying and transports the transport rack 990 to be cleaned to the unfolding mechanism 400. When waiting for the next tooling tray 980 to be transported to the disassembling and removing mechanism 300, all the lifted transport racks 990 to be cleaned are placed on the tooling tray 980, and then the disassembling and removing mechanism 300 leaves the transport rack 990 and resets.

[0060] As Figure 5 shown, the disassembling and removing mechanism 300 includes a disassembling and lifting frame 310 and a disassembling and removing component 320. The disassembling and lifting frame 310 is arranged on both sides of the disassembling and removing mechanism 300, and the disassembling and removing component 320 is slidably arranged on the disassembling and lifting frame 310. The disassembling and removing component 320 is used to insert between two adjacent transport racks 990 to be cleaned. As the disassembling and removing component 320 slides up and down on the disassembling and lifting frame 310, the transport racks 990 to be cleaned on the disassembling and removing component 320 move up and down in the vertical direction, so as to realize the process of lifting or placing down multiple transport racks 990.

[0061] The function of the unfolding mechanism 400 is to unfold the transport rack 990 to be cleaned. As Figure 6 shown, the unfolding mechanism 400 includes an unfolding component 410 and an unfolding driving component 420. The unfolding component 410 and the unfolding driving component 420 are fixedly connected. The unfolding component 410 includes a leg lever 411. The leg lever 411 is inserted into the folded upper leg 991 of a single transport rack 990 to be cleaned, specifically located between the upper leg 991 and the upper surface of the longitudinal beam 993. Driven by the unfolding driving component 420, the leg lever 411 rotates to drive the folded upper leg 991 of the transport rack 990 to unfold to an upright state, so as to unfold the transport rack 990 to be cleaned, and then the unfolding component 410 resets. There are two rotating levers on both sides of the upper conveying unit of the unfolding component 410, which can unfold the four upper legs 991 simultaneously.

[0062] The function of the cleaning mechanism 500 is to clean the unfolded transport rack 990 to be cleaned. As Figure 1 shown, the cleaning mechanism 500 includes an adsorption station 520, a cleaning station 530 and a dust suction station 540. The adsorption station 520, the cleaning station 530 and the dust suction station 540 are arranged in sequence according to the transmission direction of the transport rack 990 to be cleaned.

[0063] Among them, as Figure 1As shown, the adsorption station 520 includes an adsorption lifting frame 521 and a suction cup assembly 522. The adsorption lifting frame 521 is arranged on both sides of the adsorption station 520, and the suction cup assembly 522 is slidably arranged on the adsorption lifting frame 521. The suction cup assembly 522 includes a plurality of suction cups. The suction cup assembly 522 can achieve vertical lifting and horizontal movement on the adsorption lifting frame 521. A barrier paper is usually placed on the transport rack 990 to isolate the transport rack 990 from the fiberglass products. Some recycled papers are often used as the barrier paper to reduce costs. The plurality of suction cups of the suction cup assembly 522 are used to adsorb the barrier paper on the unfolded transport rack 990 to be cleaned and place the barrier paper at a fixed position outside the system.

[0064] As Figure 1 shown, the cleaning station 530 includes a cleaning robotic arm 531. The cleaning robotic arm 531 is provided with a brush 532, and the brush 532 is used to clean the unfolded transport rack 990 to be cleaned. The cleaning robotic arm 531 drives the brush 532 to rotate at a high speed and clean all surfaces of the transport rack 990 and the inner and outer sides of the upper leg 991. The material of the brush 532 is selected to be a material with moderate hardness and good elasticity, such as nylon filaments, to protect the surface of the transport rack 990 from being worn during the cleaning process, and the nylon filament material brush 532 will not deform and shrink after long-term use. The roller of the brush 532 has a larger diameter to adapt to the surface shape of the transport rack 990 to ensure that the concave parts of the transport rack 990 are cleaned in place. The roller of the brush 532 also has a certain length to increase the coverage area of the brush 532 and improve the cleaning efficiency. The cleaning station 530 is also provided with a dust-proof air duct 533, and the dust-proof air duct 533 is equipped with a dust suction fan to suck the cleaned dust. The outside of the cleaning station 530 can be separated by a guardrail or transparent glass to protect the working environment outside the cleaning station 530 from being clean, and at the same time isolate the cleaning robotic arm 531 from the external environment to prevent the cleaning robotic arm 531 from accidentally injuring operators during operation.

[0065] As Figure 1 shown, the dust suction station 540 includes a dust suction robotic arm 541. The dust suction robotic arm 541 is provided with a dust suction air outlet 542, and the dust suction air outlet 542 is used to suck the dust swept off the unfolded transport rack 990. The dust suction air outlet 542 can be a duckbill-shaped air duct component, and its opening has a smaller width and a larger length to effectively suck the dust that has been loosened by the brush 532 on the surface of the transport rack 990. The outside of the dust suction station 540 can also be separated by a guardrail or transparent glass.

[0066] The cleaning process of the traditional transport rack for glass fiber products often uses water washing. Even if the transport rack is dried after water washing, rust will flake off and contaminate the glass fiber products, and the contamination of iron filings is more serious than that of ordinary dust. In this application, dry cleaning is used to avoid the pollution caused by the transport rack rusting after water washing, and a cleaning robotic arm and a dust suction robotic arm are used to clean the transport rack, with high precision and good stability.

[0067] In some embodiments, as Figure 2 shown, the cleaning mechanism 500 further includes a manual cleaning station 510, and the manual cleaning station 510 is arranged between the unfolding mechanism 400 and the adsorption station 520. The manual cleaning station 510 includes a manual cleaning conveying component 511 and a rotating table component 512. The manual cleaning conveying component 511 is used to convey the unfolded transport rack 990 to the rotating table component 512, and the rotating table component 512 is used for the operator to manually rotate and clean the unfolded transport rack 990 to be cleaned. When there are stubborn stains on the transport rack 990 to be cleaned that need to be manually washed with water, or when the subsequent automatic cleaning mechanism fails, the chain perpendicular to the conveying direction on the manual cleaning conveying component 511 conveys the transport rack 990 to the rotating table component 512, and the rotating table component 512 can rotate 360°, facilitating the operator to clean the transport rack 990 at any position on the side of the rotating table component 512. The setting of the manual cleaning station 510 enriches the cleaning method of the transport rack 990, further improves the cleaning quality of the transport rack 990, and solves the problem that cleaning cannot continue when the system automatic cleaning fails.

[0068] The folding mechanism 600 is used to fold the unfolded transport rack 990 after cleaning and convey the folded transport rack 990 to the stacking mechanism 700. As Figure 7 shown, the folding mechanism 600 includes a folding component 610 and a folding driving component 620. The folding component 610 is arranged on both sides of the upper conveying unit. The folding component 610 and the folding driving component 620 are fixedly connected. The folding component 610 abuts against the upper leg 991 of the unfolded transport rack 990 after cleaning. Driven by the folding driving component 620, the folding component 610 folds the upper leg 991 of the unfolded transport rack 990 after cleaning to form the folded transport rack 990. Specifically, the folding component 610 can be a rotating lever. Four rotating levers are arranged on both sides of the upper conveying unit to correspondingly fold the four upper legs 991 of the transport rack 990.

[0069] The stacking mechanism 700 stacks the folded transport racks 990 according to a preset rule and conveys the stacked transport racks 990 to the offline mechanism 800. As Figure 8As shown, the stacking mechanism 700 includes a stacking lifting frame 710 and a stacking component 720. The stacking lifting frame 710 is disposed on both sides of the stacking mechanism 700. The stacking component 720 is slidably disposed on the stacking lifting frame 710. The stacking component 720 is used to be inserted between the folded transport rack 990 and the tooling pallet 980, specifically below the longitudinal beam 993 of the transport rack 990. As the stacking component 720 slides up and down on the stacking lifting frame 710, the folded transport rack 990 on the stacking component 720 moves up and down in the vertical direction. The stacking component 720 lifts all the transport racks 990, causing the empty tooling pallet 980 to move forward and leave. Then, the upper conveying unit continues to operate, and a new tooling pallet 980 with a new transport rack 990 arrives. The upper conveying unit stops operating. The stacking component 720 stacks all the previous transport racks 990 on top of the newly arrived transport rack 990. Finally, the stacking component 720 resets. The height of the stacked transport racks 990 by the stacking mechanism 700 should be less than and close to the height of a single unfolded transport rack 990, so that the height of conveying a stack of transport racks 990 is close to the height of a full transport rack 990 loaded with fiberglass products. The same height is conducive to the use and transfer of subsequent processes.

[0070] As Figure 1 shown, the offline mechanism 800 lifts the stacked transport rack 990 off the tooling pallet 980 and conveys it to a preset position outside the system to complete the offline of the transport rack 990. At the same time, the empty tooling pallet 980 is conveyed to the offline tooling pallet lifting mechanism 900.

[0071] As Figure 1 shown, the offline tooling pallet lifting mechanism 900 is a single-layer conveying unit. The offline tooling pallet lifting mechanism 900 includes an offline lifting component 910. The single-layer conveying unit realizes lifting under the drive of the offline lifting component 910. The single-layer conveying unit of the offline tooling pallet lifting mechanism 900 lowers the empty tooling pallet 980 to a second preset height, that is, the lower layer position, and conveys the empty tooling pallet 980 to the online tooling pallet lifting mechanism 100 through the lower conveying units of each mechanism to form the recycling and reuse of the tooling pallet 980.

[0072] In some embodiments, as Figures 1 - 2As shown in the figure, a first transition mechanism 205 is provided between the loading mechanism 200 and the removing and picking mechanism 300, a second transition mechanism 305 is provided between the removing and picking mechanism 300 and the unfolding mechanism 400, a third transition mechanism 405 is provided between the unfolding mechanism 400 and the manual cleaning station 510, a fourth transition mechanism 505 is provided between the manual cleaning station 510 and the adsorption station 520, a fifth transition mechanism 605 is provided between the folding mechanism 600 and the stacking mechanism 700, and a sixth transition mechanism 705 is provided between the stacking mechanism 700 and the offline mechanism 800. The first transition mechanism 205, the second transition mechanism 305, the third transition mechanism 405, the fourth transition mechanism 505, the fifth transition mechanism 605 and the sixth transition mechanism 705 all include a double-layer conveying unit 190. By providing the above transition mechanisms, caching is performed on each working mechanism, further increasing the smoothness of system transportation and preventing forklifts from colliding with adjacent working mechanisms.

[0073] In summary, the transport rack cleaning system of the present application realizes the full-process automatic operations of multi-layer removing and picking, unfolding, sucking off barrier paper, cleaning, dust suction, folding, and multi-layer stacking of the transport rack, improving the cleaning efficiency, reducing the labor intensity of operators, and stabilizing the cleaning effect.
