[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] like Figure 1 As shown, a commercial cleaning device, a conveyor 1, is installed on the ground and is used to transport tableware that needs to be cleaned. A trash can 2 is installed on one side of the conveyor 1; after the customer finishes the meal, he first places the chopsticks and spoons at a unified recycling area, then pours the remaining food into the trash can 2, and then puts the tableware on the conveyor 1. The track on the conveyor 1 will transport the tableware to the specified direction.

[0037] The grinder 3 is used to grind food that has not been dumped into the trash can 2. A drainage trough 31 is installed between the grinder 3 and the conveyor 1. If the customer does not dump the remaining food cleanly, the staff can pour the remaining food into the drainage trough 31, so that the remaining food enters the grinder 3 along the drainage trough 31 for grinding.

[0038] The classification box 4 is used to separate plates and bowls. The classification box 4 is connected to the conveyor 1 through an inclined guide plate 41, and a separation mechanism is installed in the classification box 4. This equipment utilizes the different appearance characteristics of plates and bowls, and cooperates with the separation mechanism in the classification box 4 to automatically classify the plates and bowls, which is convenient for subsequent recycling.

[0039] The dishwasher 5 is used for washing tableware. The dishwasher 5 is connected to the classification box 4 through a first conveyor belt 51 and a second conveyor belt 52. A baffle 53 is provided between the first conveyor belt 51 and the second conveyor belt. The dishwasher 5 of the present invention adopts a long dragon-type commercial dishwasher 5, which is divided into a main washing area, a rinsing area and a drying and disinfection area in sequence along the conveying direction. The first conveyor belt 51 and the second conveyor belt 52 are respectively used for separately conveying plates and bowls, and a baffle 53 is provided in the middle to prevent the plates and bowls from being mixed up and causing inconvenience in classification and storage.

[0040] like Fig. 9 , Fig.10 As shown, the stacker 6 is used for stacking and storing plates. A cavity 61 is provided on the stacker 6. A support plate 62 is fixedly connected in the cavity 61. One end of the support plate 62 is in contact with the first conveyor belt 51. The first conveyor belt 51 can push the plates into the cavity 61. There is a height difference between the support plate 62 and the first conveyor belt 51. A transition slope 621 is formed at one end of the support plate 62 close to the first conveyor belt 51. The plates entering the stacker 6 through the first conveyor belt 51 will be lifted along the transition slope 621 under the guidance of the transition slope 621. At this time, there is also a height difference between the next plate and the previous plate that has entered the stacker 6. The next plate can lift up the previous plate above it in the height direction under the push of the first conveyor belt 51, and then be inserted under the previous plate, and so on, to achieve the purpose of automatic stacking.

[0041] like Fig.11 , Fig.12 As shown, the collecting box 7 is used to store bowls. The collecting box 7 is installed at the end of the second conveyor belt 52. A carrying plate 71 is slidably installed in the collecting box 7. An elastic member 74 is installed between the carrying plate 71 and the collecting box 7. Due to the presence of the elastic member 74, the carrying plate 71 is closer to the second conveyor belt 52 when it is unloaded, so as to prevent the bowls from falling from the second conveyor belt 52 into the collecting box 7 and causing damage. When the bowls are continuously accumulated, the carrying plate 71 will move downward and squeeze the elastic member 74 to prevent the bowls from falling out of the collecting box 7, thereby achieving the effect of automatically recovering the bowls.

[0042] like Figure 2 , Figure 3 and Figure 4As shown, the separation mechanism includes a reversing component, which includes a partition 42, a pushing roller 43, an abutting roller 44 and a third conveyor belt 45. There is a gap between the partition 42 and the guide plate 41 that only allows plates to pass through. The pushing roller 43 is rotatably set on the partition 42 and driven by a motor. The abutting roller 44 is rotatably connected to the classification box 4 and driven by a motor. A number of soft paddle pieces 431 are fixedly connected to the pushing roller 43, and a number of hard paddle pieces 441 are fixedly connected to the abutting roller 44. The third conveyor belt 45 is inclined and installed between the partition 42 and the first conveyor belt 51. When a plate with a bowl placed on it falls along the inclined guide plate 41, one side of the plate will abut against the partition 42. At this time, under the action of inertia, the bowl in the plate will continue to move forward, thereby separating from the plate, and there is a gap between the partition 42 and the guide plate 41 that only allows the plate to pass through, so the plate will move along The gap between the partition 42 and the guide plate 41 falls, and the plate that was originally opening upward now opens in the direction of the partition 42. Because the push roller 43 is rotatably set on the partition 42 and driven by a motor, when the plate contacts the push roller 43, it will be pushed by the push roller 43 and move along the extension direction of the partition 42 to prevent the plate from staying on the partition 42. When the plate moves to the end of the partition 42, because the abutment roller 44 is rotatably connected to the classification box 4 and driven by a motor, the abutment roller 44 will knock the plate that moves to the end of the partition 42, thereby making the plate tilt up and fall onto the inclined third conveyor belt 45. At this time, the opening of the plate becomes upward again, and under the transmission of the third conveyor belt 45, the plate enters the first conveyor belt 51 with the opening facing upward, and is then transported to the dishwasher 5 for cleaning via the first conveyor belt 51. The separation mechanism of this product also includes a fourth conveyor belt 46. There is a height difference between the fourth conveyor belt 46 and the second conveyor belt 52, and one end of the fourth conveyor belt 46 is in contact with the partition 42. In the above process, the bowl is thrown out due to inertia when the plate abuts against the partition 42, and thus falls into the fourth conveyor belt 46 along the arc chamfer on the partition 42. Since there is a height difference between the fourth conveyor belt 46 and the second conveyor belt 52, the fourth conveyor belt 46 can continuously make the bowls above it fall onto the second conveyor belt 52, thereby reaching the dishwasher 5 via the second conveyor belt 52.

[0043] For example Figure 4 As shown, the partition 42 is "L"-shaped, and a plurality of auxiliary rods 47 are rotatably provided on the partition 42. By providing the rotatable auxiliary rods 47, when the plate contacts the auxiliary rods 47, the auxiliary rods 47 will rotate accordingly, thereby reducing the friction between the plate and the partition 42, making the transfer process smoother.

[0044] like Figure 5 , Figure 6 and Figure 7As shown, a plurality of hooking members 511 are fixedly provided on the first conveyor belt 51 along the transmission direction, and the hooking members 511 are inclinedly arranged. By arranging the hooking members 511 on the first conveyor belt 51, when the plate falls onto the first conveyor belt 51, it will be abutted by the hooking members 511 and climb up, so that the transfer process of the plate is more stable. A plurality of protrusions 521 are fixedly provided on the second conveyor belt 52 along the transmission direction. When a bowl falls onto the second conveyor belt 52, since the bowl is generally round in shape, the protrusions 521 are arranged. When the bowl adjusts its posture on the second conveyor belt 52 to abut against the protrusions 521, it will be carried by the protrusions 521 to the dishwasher 5, so as to prevent the bowl from rolling off the conveyor belt.

[0045] like Figure 8 and Fig.13 As shown, a plurality of hooking members 511 are arranged at intervals along the width direction of the first conveyor belt 51, and an avoidance groove 622 for allowing the hooking member 511 to pass through is opened on the support plate 62. After the plate is transported by the first conveyor belt 51 and is cleaned and disinfected through the dishwasher 5, it continues to move along the conveying direction of the first conveyor belt 51, and the plate will be transported to the stacker 6. When the plate approaches the stacker 6, it is pushed by the hooking member 511, and the plate will be lifted along the slope direction of the transition slope 621 and enter the stacker 6. The hooking member 511 After passing through the avoidance groove 622 and moving to the bottom of the first conveyor belt 51, when the next plate is pushed by the hook member 511 to approach the stacking machine 6, the next plate can be lifted along the transition slope 621 and lift up the previous plate and then inserted under the previous plate. Due to the existence of the hook member 511, the next plate is pushed by the first conveyor belt 51 and the hook member 511 when being inserted, which is equivalent to the movement of the next plate having a power source, so it is sufficient to resist the gravity of the upper plate and be inserted into the bottom layer, thereby completing the effect of automatically stacking and storing plates.

[0046] For example Fig. 9 , Fig.10As shown, cavities 61 are symmetrically provided on both sides of the stacker 6, and support plates 62 are fixedly provided in the cavities 61 on both sides. An AGV chassis 8 is installed at the bottom of the stacker 6, and the AGV chassis 8 is also called an intelligent transport trolley. The AGV chassis 8 can change the direction of the stacker 6. A trigger button 611 is installed on the top of the cavity 61, and the trigger button 611 is electrically connected to the AGV chassis 8. A matching first position sensor 81 is installed on the AGV chassis 8 and the dishwasher 5. When the cavity 61 on one side of the stacker 6 is stacked with a high enough plate, the plate at the top will touch the trigger button 611. After the trigger button 611 is triggered, the transportation of the first conveyor belt 51 will be suspended first, and then an instruction will be sent to the AGV chassis 8. At this time, the AGV chassis 8 will start to move and change the direction of the stacker 6, so that the cavity 61 on the other side where no plates are stacked will face the first conveyor belt 51, and will be displaced to the original matching position through the first position sensor 81, and then the operation of the first conveyor belt 51 will be restored to enable it to continue to transport the plates to the cavity 61 for stacking and storage.

[0047] For example Fig.11 , Fig.12 As shown, there are multiple collection boxes 7, and an AGV chassis 8 is installed at the bottom of the collection boxes 7. A weight sensor 72 is installed on the load-bearing plate 71. The weight sensor 72 is electrically connected to the AGV chassis 8. The AGV chassis 8 on the collection box 7 and the dishwasher 5 are equipped with a matching second position sensor 82. When bowls continue to fall into the collection box 7, the weight sensor 72 will receive the total weight of these bowls. When this weight reaches a certain value, it means that a corresponding number of bowls have been received. At this time, the weight sensor 72 will issue an instruction to temporarily pause the operation of the second conveyor belt 52, and then send an instruction to the AGV chassis 8 to move the collection box 7, and then send an instruction to prompt another AGV chassis 8 to drive another collection box 7 to move, and use the second position sensor 82 for positioning, so that the other empty collection box 7 moves to the end of the second conveyor belt 52 to continue collecting bowls.

[0048] like Fig.12 As shown, a limiting block 711 is fixedly connected to the supporting plate 71, and a limiting groove 73 is provided on the collecting box 7. The limiting block 711 can extend into the limiting groove 73 and slide along the limiting groove 73. This design can enable the supporting plate 71 to slide along the direction specified by the limiting groove 73 to avoid one side from tilting.

[0049] Finally, if Fig. 9 and Fig.13As shown, a slide groove 63 is provided on the stacking machine 6, and a blocking member 64 is slidably arranged in the slide groove 63. A portion of the blocking member 64 extends into the slide groove 63, and the other portion of the blocking member 64 can form a blockage for the opening of the cavity 61. The cross-sections of the slide groove 63 and the portion of the blocking member 64 extending into the slide groove 63 are both "T"-shaped. By setting the blocking member 64, after the plates in the stacking machine 6 are stacked to a certain height, if they are accidentally tilted toward the opening direction of the cavity 61, the blocking member 64 can form an abutment limit to prevent them from tipping over and falling. Since the blocking member 64 is slidably arranged in the slide groove 63, when the stacking and storage is completed, the operator can slide the blocking member 64 to both sides when he needs to take the plate so that it no longer forms a blockage for the cavity 61 and the plate can be taken out of the cavity 61.

[0050] Working principle: After the consumers finish their meals, they place small items such as chopsticks and spoons at the recycling area, which is set up by the canteen itself and will not be elaborated here. Then, the remaining food in the plates and bowls is dumped into the trash can 2, and then the plates and bowls are placed on the conveyor 1. The plates and bowls move along the conveying direction of the conveyor 1. A staff member is arranged between the conveyor 1 and the grinder 3. If the customer does not dump the remaining food in the plates and bowls clean, the staff member needs to perform a secondary cleaning and pour the remaining food into the drainage trough 31, so that the remaining food enters the grinder 3 along the drainage trough 31 for crushing. The plates and bowls without residual food enter the classification box 4 along the conveying direction of the conveyor 1. The classification box 4 separates the plates and bowls, and sends them to the dishwasher 5 via the first conveyor belt 51 and the second conveyor belt 52 for cleaning, drying and disinfection, and the plates and bowls are respectively stored in the stacker 6 and the collection box 7. The whole process has a high degree of automation and requires a small amount of manpower.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
