Description

Technical Field

[0001] This invention relates to the field of washing technology, and in particular to a washing system. Background Technology

[0002] Currently, intelligent industrial washing systems are undergoing rapid technological updates and iterations within the rapidly developing industry. For example, patent 201810322448.3 discloses an automatic washing system comprising: a conveyor distribution line with a first conveyor channel for conveying linens; a washing device for washing linens; and a loading assembly for transporting linens from the first conveyor channel into the washing device. The technical problem this patent solves is that large industrial washing machines handle large volumes of laundry, and manually transporting linens is difficult and inefficient, affecting the overall washing efficiency. The beneficial effect is that a conveyor belt-type distribution line automatically transports soiled linens into the washing device (integrated washing-rinsing-dehydration), which then proceeds to the subsequent drying process. This patent addresses the efficiency issue of transitioning from manual to automatic feeding. However, considering current washing standards that require separation, the washing equipment in this patent uses an integrated washing-rinsing-spinning machine. This means that both dirty and clean linens enter and exit through the same washing door, making effective separation between the two types of linens impossible. Therefore, it cannot meet the new washing standards. Automated feeding structures using conveyor belts also have their own drawbacks.

[0003] Therefore, there is an urgent need for a new intelligent industrial washing system. Summary of the Invention

[0004] To overcome the above-mentioned technical problems, this application provides a washing system that can effectively separate dirty linens from clean linens, and the conveying device in the washing system can also effectively avoid the drawbacks of conveyor belts.

[0009] Optionally, the conveying device includes a hollow hopper, a moving mechanism, a pressing mechanism, and a switching mechanism. The hollow hopper is used to hold linens. The moving mechanism for moving the conveying device is located on one side of the hopper. The pressing mechanism is located inside the hopper and presses the linens in the conveying device against the outlet of the hopper. The switching mechanism is located at the bottom of the hopper and is used to open or close the outlet of the conveying device.

[0010] Optionally, the pressing mechanism includes a lower pressing structure, and there are one or more sets of lower pressing structures arranged in parallel with gaps between them. Adjacent sets of lower pressing structures are fixedly connected by connecting rods. The lower pressing structure includes a lower pressing cylinder, a pressing head, and a lower assembly. The pressing head is located at the bottom of the lower assembly, and the lower pressing cylinder is located inside the lower assembly. One end of the lower pressing cylinder penetrates the lower assembly and is fixedly installed at the top opening of the hopper.

[0023] The present application will be further described in detail below with reference to all the accompanying drawings.

[0024] like Figures 1 to 5As shown, a washing system includes a platform 1, washing machines 2, and a conveying device 3 for transporting linens. The platform 1 is constructed above multiple washing machines 2 arranged side-by-side. A linen inlet is located vertically above each washing machine 2, and a linen outlet is located on the side of each washing machine 2. The conveying device 3 has an inlet at its top and an outlet at its bottom. Multiple slots 6 are formed on the platform 1, each slot 6 corresponding to a linen inlet of one washing machine 2. The conveying device 3 moves horizontally and vertically on the platform 1 to automatically feed linens into the washing machine 2. By adding the steel structure platform 1 and the corresponding washing machines 2, dirty and clean linens can be effectively separated. The specially structured conveying device 3 in the washing system also effectively avoids the drawbacks of conveyor belts, achieving more flexible linen transport and relatively improved feeding efficiency. Furthermore, the automated feeding and conveying device 3 of this application is applicable to industrial washing machines 2 with the feed inlet at the top vertically, such as CN 105780403 B, an industrial washing and dewatering machine. The side door of the washing machine 2 is used for discharging linens, and the opening at the top vertically is specifically for feeding linens into the washing machine 2. In the overall technical solution of this application, a washing machine 2 integrating washing, rinsing, and dewatering is still used. This ensures the overall efficiency of the process (washing-rinsing-dewatering) while reducing unnecessary conveying processes. Some technologies in the industry separate washing and dewatering into different functional devices to meet the area separation requirements of washing standards. However, such separation reduces the overall efficiency of washing-rinsing-dewatering and increases the cost of additional conveying equipment. By adding a steel structure platform 1, the washing space can be divided into areas. The washing machine 2, water treatment equipment, water-saving equipment, etc., can all be installed under the platform 1, saving space costs. The area above platform 1 serves as the receiving, sorting, and loading area for soiled linens, i.e., the soiled area, where fabric sorting can also be performed. Below platform 1, the area is further divided into a general area and a clean area. Soiled linens are transported directly to the area above platform 1 and a certain quantity is placed into the conveyor device 3. The horizontal movement of the conveyor device 3 transports the soiled linens to the corresponding washing machine 2. The vertical movement of the conveyor device 3 causes the outlet to pass through the trough 6 and sink into the linen inlet of the washing machine 2, where linens are placed vertically above the washing machine 2. After placement, the conveyor device 3 moves vertically upwards. The washing machine 2 then enters the washing process. After completion, the clean linens are removed from the linen outlet on the horizontal side of the washing machine 2. Soiled linens above platform 1 and clean linens below platform 1 are stored in separate areas, effectively isolating them. The limitation of the washing machine 2 in this application also helps to isolate soiled and clean linens to a certain extent. Dirty linens can be piled up at various locations on platform 1, especially near each slot 6. By moving the conveyor 3 horizontally, dirty linens at any location on platform 1 can be transported to any washing machine 2.When the conveyor 3 is not in operation, i.e., during maintenance or shutdown, linens can also be manually added to the washing machine through the slot 6.

[0025] A partition wall 4 is provided at the end of the platform 1 near the linen outlet of the washing machine 2. Furthermore, the partition wall 4 is approximately flush with the front panel of the washing machine 2 (the side where the linen outlet is located). The partition wall 4 is vertically connected to the platform 1 and is higher than the horizontal plane of the platform 1. The position and height of the partition wall 4 effectively separate the soiled and clean areas.

[0026] A guide rail 5 is provided on the platform 1 near the slot 6, or a horizontal guide rail 5 is provided on the partition wall 4. The conveying device 3 moves horizontally on the platform 1 via the guide rail 5. The specific installation position of the guide rail 5 can be determined according to the actual washing plant site. The guide rail 5 is connected to the first sliding mechanism 81 in the conveying device 3, realizing the horizontal movement of the conveying device 3 on the platform 1.

[0027] The conveying device 3 includes a hollow hopper 7, a moving mechanism 8, a pressing mechanism 9, and a switching mechanism 10. The hollow hopper 7 is used to hold linens. The moving mechanism 8, used for moving the conveying device 3, is located on one side of the hopper 7. The pressing mechanism 9 is located inside the hopper 7 and presses the linens in the conveying device 3 against the outlet of the hopper 7. The switching mechanism 10 is located at the bottom of the hopper 7 and is used to open or close the outlet of the conveying device 3. The feeding and discharging of the conveying device 3 is vertical, not horizontal like a conveyor belt. The top and bottom of the hopper 7 are open, forming the feed inlet and discharge outlet of the hopper 7, respectively. Linens enter the hopper 7 through the feed inlet and are discharged through the discharge outlet. The hopper 7 consists of a hopper plate and a hopper frame. Figure 2 The upper chamber is shown after removing three chamber plates to better demonstrate its internal structure. The funnel-shaped chamber 7 can extend below the horizontal plane of the washing machine's linen inlet during vertical movement. The pressing mechanism 9 allows the washing machine 2 to reach the rated filler volume quickly, overcoming the difficulty of achieving the rated filler volume when relying on gravity filling.

[0028] The pressing mechanism 9 includes a lower pressing structure, which has one or more sets. These sets of lower pressing structures are arranged in parallel with gaps between them, and are fixedly connected to adjacent sets of lower pressing structures via connecting rods 91. The number of lower pressing structures refers to the number installed on one side of the hopper 7. Those skilled in the art can easily combine these designs to extend the lower pressing structures to two or three sides of the hopper 7. The lower pressing structure includes a pressing cylinder 92, a pressing head 93, and a lower assembly 94. The pressing head 93 is located at the bottom of the lower assembly 94, and the pressing cylinder 92 is located inside the lower assembly 94. One end of the pressing cylinder 92 penetrates the lower assembly 94 and is fixedly installed to the top opening of the hopper 7. The other end of the pressing cylinder 92 penetrates the lower assembly 94 and is fixedly installed to the pressing head 93. One side of the lower assembly 94 is slidably connected to the inner side of the hopper 7. The parallel arrangement of multiple sets of lower pressing structures is for better synchronized pressing. The lower pressing structure is slidably connected to the inside of the hopper 7 via one side of the lower assembly 94. Under the action of connecting rod 91, multiple sets of pressing structures form a whole, making the sliding connection with the hopper body 7 simpler and the sliding more synchronized. The purpose of the sliding connection is to prevent torsion during cylinder extension and retraction.

[0029] There are two pressing cylinders 92, arranged in parallel, with their telescopic rods facing each other. One pressing cylinder's telescopic rod is fixedly installed to the top opening of the chamber 7, while the other pressing cylinder's telescopic rod is fixedly installed to the pressing head 93. This technology shortens the installation space while maximizing the telescopic process, thus improving the pressing effect and efficiency.

[0030] The pressing mechanism 9 also includes an upper pressing structure, which is used to press the top of the linens inside the bin 7 and to open and close the inlet of the bin 7. The upper pressing structure includes a fixed plate 95, a pressing plate 96, and an upper pressing cylinder 97. One end of the fixed plate 95 is fixedly installed to the lower pressing structure, and the other end of the fixed plate 95 is hinged to one end of the pressing plate 96. One end of the upper pressing cylinder 97 is fixedly installed on the fixed plate 95 through a first connecting piece 98, and the other end of the upper pressing cylinder 97 is connected to the pressing plate 96 through a second connecting piece 99. The extension and retraction of the upper pressing cylinder 97 controls the flipping of the pressing plate 96. The pressing plate 96 can both open and close the inlet of the bin 7 and press the linens as the lower pressing structure moves downward, specifically pressing the top of the linens inside the bin 7. When the upper pressing cylinder 97 is extended, it can firmly press the pressing plate 96 onto the linens, which is the pressing process. When the upper pressure cylinder 97 retracts, the pressure plate 96 flips, fully exposing the feed inlet of the hopper 7, at which point the hopper 7 is in the feeding process. The flipping of the pressure plate 96 is powered by the upper pressure cylinder 97, and the hinge between the pressure plate 96 and the fixed plate 95 provides a support point for the flipping of the pressure plate 96. The bottom of the fixed plate 95 is fixedly connected to the side of the lower assembly 94 in the two sets of lower pressing structures. The downward movement of the lower pressing structure drives the fixed plate 95 downward, which in turn drives the entire upper pressing structure downward.

[0031] The switching mechanism 10 is located on the outside of the bin body 7. The switching mechanism 10 includes a power component 17, a follower component 11, a transmission mechanism, and a material gate. One end of the power component 17 is fixed to the top opening of the bin body 7, and the other end of the power component 17 is connected to one end of the transmission mechanism. The other end of the transmission mechanism is hinged to the material gate, which is located at the outlet of the bin body 7. The opening and closing of the material gate controls the opening and closing of the outlet of the bin body 7. A follower component 11 is located at each end of the material gate along its length. The follower component 11 is mounted on the inner side of the bin body 7 by a fixing component, with the end of the follower component 11 closest to the outlet of the bin body 7. The switching mechanism 10 serves three purposes: first, it can flip the material gate to open the outlet of the bin body 7 when feeding material; second, it can lock the outlet of the bin body 7 during horizontal movement; and third, it can limit the feeding process of the outlet of the bin body 7 by adjusting the material gate in conjunction with the follower component 11. The follower 11 can be integral or separate. The material of the follower 11 can be flexible or rigid. The follower 11 can be any of the existing technologies, such as a folded structure or a multi-layered stacked structure. The illustration shows a folded follower 11.

[0032] There are two sets of the power component 17 and the transmission mechanism, with one set of power component 17 used in conjunction with one set of transmission mechanism. One set of power component 17 and one set of transmission mechanism are respectively installed on two opposite sides of the hopper body 7. The transmission mechanism includes a first hinge rod 13, a second hinge rod 14, a sector member 15, and a transmission block 16. The transmission block 16 has three connecting slots. One horizontally positioned upper connecting slot connects to the power component 17. The other two horizontally positioned lower and spaced apart connecting slots are respectively hinged to one end of the first hinge rod 13 and one end of the second hinge rod 14. The other end of the first hinge rod 13 is hinged to the sector edge of one sector member 15, and the other end of the second hinge rod 14 is hinged to the sector edge of another sector member 15. The two sector members 15 connected to the first hinge rod 13 and the second hinge rod 14 are arranged parallel to each other. One straight edge of a single sector member 15 is fixedly connected to one end of the material gate. The power component 17 can be a cylinder or other similar component. A power unit 17 and a transmission mechanism are respectively installed at both ends of the material gate, which improves the stability of opening and closing the material gate and better meets the control requirements of linens. The cylinder rod of the power unit 17 extends to drive the transmission block 16 downward, which in turn drives the first hinge rod 13 and the second hinge rod 14, and with the assistance of the sector member 15, flips the material gate.

[0033] The moving mechanism 8 includes a first sliding mechanism 81 and a second sliding mechanism 82. One side of the first sliding mechanism 81 is connected to one side of the second sliding mechanism 82 via a frame member 83, and the other side of the second sliding mechanism 82 is connected to the chamber 7. The chamber 7 moves back and forth between multiple washing machines 2 via the first sliding mechanism 81 and moves back and forth vertically via the second sliding mechanism 82. The discharge port of the chamber 7 extends below the slot 6 and connects with the linen inlet of the washing machine 2. The first sliding mechanism 81 is connected to the guide rail 5 and slides with the help of the guide rail 5. The first sliding mechanism 81 and the second sliding mechanism 82 can adopt any kind of moving form in the industry, such as a guide rail type moving mechanism 8, etc. The function of the first sliding mechanism 81 and the second sliding mechanism 82 is to assist the horizontal and vertical movement of the chamber 7. To achieve the movement, those skilled in the art can use any kind of moving structure in the prior art. The guide rail type moving structure is preferred in the illustration of this application. The second sliding mechanism 82 is mainly for a single washing machine 2, and the horizontal movement is for the movement between multiple washing machines 2. The horizontal movement is reciprocating, and the feeding is flexible. The first sliding mechanism 81 specifically refers to the slider that is slidably connected to the guide rail 5. The second sliding mechanism 82, specifically disclosed in the accompanying drawings of this application, includes a structure of a vertical slider, a vertical guide rail, a cylinder, a moving plate, etc. The cylinder extends and retracts, causing the moving plate to move, which in turn causes the chamber 7 to move relative to the vertical guide rail.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
