Description

Technical Field

[0001] The present invention relates to the field of lunch box cleaning equipment, and in particular to an intelligent production line for lunch boxes. Background Art

[0002] In the prior art, centralized meal delivery typically uses separate tableware with a box body and a lid to prevent contamination during transportation. The separate tableware includes a box body and a lid, with an open top and a lower bottom. The inner edge of the lower end of the lid is matingly connected to the outer edge of the upper end of the box body. In a central kitchen, the lid is placed on the box body containing the meal, and the lid and the box body are snap-fitted together for centralized transportation to the user. After the meal is finished, the lunch box and the lid are snap-fitted together and transported to a centralized cleaning workshop by a dedicated vehicle. Before cleaning, a large amount of manpower is required to disassemble the lid and the box body of each separate tableware, and manually dump the uneaten food in the lunch box into a trash can. After dumping the remaining food, the tableware needs to be pre-washed before cleaning, including pre-rinsing or soaking to remove residue on the tableware. After the main residue is removed, the tableware is then put into a dishwashing and box washing machine for cleaning. This consumes a lot of manpower and has low work efficiency. Therefore, the present invention designs an intelligent lunch box cleaning production line. Summary of the Invention

[0034] The beneficial effects of the present invention are:

[0035] 1. When the lunch box is horizontally transported to the initial position of the cover guide rail by the first conveying component, the second conveying component drives the upper push block to rotate. The upper push block presses against the upper cover of the lunch box, so that the upper cover moves upward along the cover guide rail. The lower push block continues to move horizontally under the action of the first conveying component, realizing the separation of the lunch box cover, replacing the traditional manual operation and improving work efficiency.

[0036] 2. When the upper push block and the lower push block are molded together, the lower end of the upper push block matches the rectangular groove of the lower push block. At this time, the upper push block and the lower push block are between the two lunch boxes. The width of the lower push block is greater than the width of the rectangular groove, which keeps a certain distance between the lunch box and the upper push block in the vertical state, preventing the upper push block from pressing the upper cover under the action of the rotating wheel;

[0037] 3. When the lunch box is transported to the initial position of the cover guide rail, the inner rib is at the lower end surface of the upper cover. Under the action of the upper push block, the upper cover moves upward along the cover guide rail, and the inner rib provides an upward force, thereby separating the tightly combined upper cover and box body.

[0038] 4. The present invention provides a system for automatic lid opening and conveying of split tableware, automatic dumping of remaining food, automatic pre-washing and de-slag removal, and upper and lower double-layer cleaning of boxes and lids. The system has a simple structure, high efficiency, and is easy to manufacture and assemble. The recovered tableware is placed on the conveyor belt of the conveying device manually or by a robot. The tableware is separated from the box body and the lid during the transportation. After the box body is separated, the remaining food in the box body is automatically dumped into the residue recovery conveyor. The box body and the lid are respectively conveyed to the corresponding upper and lower conveyor belts in the pre-washing and de-slag machine. In the pre-washing and de-slag system, the lunch box and the lunch lid are pre-rinsed with high-temperature washing water, and the remaining residue on the box and the lid is washed into the deslag discharge mesh belt, and the remaining solid residue is conveyed to the residue collection box outside the equipment; the pre-washed tableware enters the cleaning system along the upper and lower conveyor belts for cleaning, which saves labor costs, improves work efficiency, and further improves the automation and intelligence level of commercial kitchens, filling the product gap of automatic lid opening, de-slag removal, pre-washing and de-slag removal, and cleaning of lunch boxes at home and abroad. DETAILED DESCRIPTION

[0039] The following is a clear and complete description of the concept, specific structure and technical effects of the present invention in conjunction with the embodiments and drawings, so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other in the absence of conflict. It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to another feature, or it can be indirectly fixed or connected to another feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the various components of the present invention in the drawings.

[0040] like Figure 1 and 2As shown, an intelligent lunch box cleaning production line includes a lid-lifting and slag-discharging device 1, which is used to complete the separation and slag discharge of the cover and the box body; a pre-cleaning slag remover 2, which is arranged at the end of the lid-lifting and slag-discharging device 1, and is used to pre-clean the cover and box body after separation; a cleaning machine 3, which is arranged at the end of the pre-cleaning slag remover 2, and is used to clean the pre-cleaned box body and lid separately; wherein, the lid-lifting and slag-discharging device 1 includes a platform 5, a first conveying component 6, a second conveying component 7, a lid-separating component 8 and a flipping and slag-discharging device 9; the first conveying component 6 is arranged at the end of the platform 5, and transports the lunch box on the platform 5 forward along the transport direction; the second conveying component 7 is obliquely arranged above the first conveying component 6, and transports the box body forward along the transport direction; the lid-separating component 8 is arranged between the first conveying component 6 and the second conveying component 7, and separates the box and the lid of the lunch box on the first conveying component 6; the flipping and slag-discharging device 9 is arranged at the end of the second conveying component 7, and the flipping and slag-discharging device 9 flips the box body. The worker places the lunch box on the platform 5, and the first conveying component 6 starts to transport the lunch box forward. When it is transported to the lid separation component 8, the upper cover and the box body are separated by the action of the lid separation component 8. The box body is moved horizontally by the first conveying component 6, and the upper cover is moved upward along the lid guide rail 81 by the second conveying component 7. The overturning and slag discharge device overturns the box body onto the lower component of the pre-cleaning slag remover 2. The cover body is directly moved to the upper component of the pre-cleaning slag remover 2. The cover body 10 and box body 11 move forward, and the water column at the bottom sprays upward to pre-clean the cover body 10 and box body 11. After pre-cleaning, the box body 10 and cover body 11 are conveyed to the cleaning machine for rinsing.

[0041] Furthermore, the first conveying component 6 includes a first main rotating wheel 61, a first secondary rotating wheel 62, a first rotating motor, and a first synchronous belt 63. The first main rotating wheel 61 and the first secondary rotating wheel 62 are arranged along the direction of transporting the lunch box. The first synchronous belt 63 is tensioned between the first main rotating wheel 61 and the first secondary rotating wheel 62. The first rotating motor is arranged on one side of the first synchronous belt 63 and drives the first main rotating wheel 61. When the first rotating motor is started, it drives the first synchronous belt 63 to rotate. A plurality of upper pushing blocks 82 are equidistantly distributed on the first synchronous belt 63. The upper pushing blocks 82 can push the upper cover to move upward along the cover guide rail 81.

[0042] Furthermore, the second conveying component 7 includes a second main rotating wheel 71, a second secondary rotating wheel 72, a second rotating motor, and a second synchronous belt 73. The second main rotating wheel 71 and the second secondary rotating wheel 72 are arranged along the transport direction of the lunch box lid. The second synchronous belt 73 is tensioned between the second main rotating wheel 71 and the second secondary rotating wheel 72. The second rotating motor is arranged on one side of the second synchronous belt 73 and drives the second main rotating wheel 71. The second rotating motor drives the second synchronous belt 73 to rotate. A plurality of downward pushing blocks 83 are equidistantly distributed on the second synchronous belt 73. The downward pushing blocks 83 cause the box body to move forward in the horizontal direction.

[0043] Please refer to Figures 3 to 7 The lid-splitting component 8 includes a lid guide rail 81, an upper push block 82, and a lower push block 83. The lid guide rail 81 is tilted and arranged between the first conveying component 6 and the second conveying component 7. The upper push block 82 is synchronized with the second conveying component 7, and the lower push block 83 is synchronized with the first conveying component 6. When the lunch box is horizontally transported to the initial position of the lid guide rail 81 by the first conveying component 6, the second conveying component 7 drives the upper push block 82 to rotate. The upper push block 82 presses against the upper lid of the lunch box, causing the upper lid to move upward along the lid guide rail 81. The lower push block 83 continues to move horizontally under the action of the first conveying component 6.

[0044] The upper push block 82 is a cube structure with a rectangular groove 821 on its end surface; the lower push block 83 is a cube structure with its end matched in the rectangular groove 821. When the lid-separating component 8 separates the upper lid and the box body, the upper push block 82 and the lower push block 83 are used to move the upper lid and the box body in two different directions, thereby achieving separation of the upper lid and the box body. When the upper push block 82 and the lower push block 83 are molded together, the lower end of the upper push block 82 matches the rectangular groove 821 of the lower push block 83. At this time, the upper push block 82 and the lower push block 83 are located between the two lunch boxes. The width of the lower push block 83 is greater than the width of the rectangular groove 821, maintaining a certain distance between the lunch boxes and the upper push block 82 in the vertical state, preventing the upper push block 82 from pressing the upper lid under the action of the rotating wheel.

[0045] When the upper cover and the box body of the lunch box are tightly combined, external force is generally required to separate the upper cover and the box body. At this time, an inner rib 811 is required to be provided on the cover guide rail 81 along the length direction. When the lunch box is transported to the initial position of the cover guide rail 81, the inner rib 811 is at the lower end surface of the upper cover. When the upper cover moves upward along the cover guide rail 81 under the action of the upper pushing block 82, the inner rib 811 provides an upward force, thereby separating the tightly combined cover body 10 and box body 11, ensuring the separation of the tightly combined cover body 10 and box body 11.

[0046] The technical solution of the present invention also includes a photoelectric detection system, which includes an ultra-high detection photoelectric sensor and a lid non-separation sensor. The ultra-high detection photoelectric sensor is arranged at the initial position of the first conveying system. When the lunch box passes through the ultra-high detection photoelectric sensor, the photoelectric switch triggers a signal, and the lid conveying motor system suspends operation; the lid non-separation sensor is arranged on one side of the lid guide rail. Unseparated lunch boxes and non-standard lunch boxes will trigger the lid non-separation sensor, and the lid conveying motor system suspends operation.

[0047] The technical solution of the present invention also includes a control system, which controls the cover-lifting and slag-discharging device, the pre-cleaning slag remover and the cleaning machine, thereby realizing the automation of the device of the present invention.

[0048] Please refer to Figures 3, 8 and 9. The turning and dumping device 9 includes a flap 91 and a hopper 92. The flap 91 is rotatably arranged at the end of the second conveying member 7, and the hopper 92 is arranged below the flap 91. After the lid and box body are separated, the box body moves onto the flap 91 and is turned over by the flap 91. The residue in the box body is poured into the feed hopper 92. After the box body is turned over, it is turned over to the pre-cleaning and de-slag machine for pre-cleaning.

[0049] The pre-washing and slag removal machine 2 includes an upper pre-washing conveyor mesh belt 21, a lower pre-washing conveyor mesh belt 22, and a pre-washing water column 23; the upper pre-washing conveyor mesh belt 21 is arranged above the lower pre-washing conveyor mesh belt 22, and the pre-washing water column 23 is arranged below the lower pre-washing conveyor mesh belt 22. The lid is conveyed onto the upper pre-washing conveyor mesh belt 21, and the box body is flipped and conveyed onto the lower pre-washing conveyor mesh belt 22. The pre-washing water column 23 pre-cleans the box body and lid body.

[0050] The cleaning machine 3 includes an upper cleaning conveyor mesh belt 31, a lower cleaning conveyor mesh belt 32, and a cleaning water column 33. The upper cleaning conveyor mesh belt 31 is arranged above the lower cleaning conveyor mesh belt 32, and the cleaning water column 33 is arranged below the lower cleaning conveyor mesh belt 32. After pre-cleaning, the lid and box body enter the upper cleaning conveyor mesh belt 31 and the lower cleaning conveyor mesh belt 32, respectively, and the cleaning water column 33 cleans the lid and box body again.

[0051] The working principle of the device of the present invention:

[0052] The lunch box collection box filled with lunch boxes that need to be uncovered and emptied of residues is sent to the end position of this equipment by an automatic conveyor line or manually, and the lunch boxes that need to be uncovered and emptied of residues are taken out from the lunch box collection box manually and placed one by one on the conveying track of the lunch box conveying device (this equipment has a total of four rows of conveying tracks. According to the production capacity requirements of the equipment, two people are required to take out the lunch boxes that need to be uncovered and emptied of residues from the lunch box collection box at the same time, and then place them on the conveying track of the lunch box conveying device); the motor drives the conveying chain to perform intermittent motion (that is, it is cycled between operation and stop), and during the stop period, the lunch boxes that need to be uncovered and emptied of residues are manually placed on the conveying track of the lunch box conveying device; during its operation, the lower pushing block fixed on the conveying chain pushes the lunch boxes that need to be uncovered and emptied of residues on the conveying track to the uncovering and emptying device; the uncovering and emptying device separates the lunch box lid and the lunch box body of the lunch box that needs to be uncovered and emptied of residues, and enters different conveying tracks, and the lunch box lid moves along the lunch box lid conveying device The lunch box body moves forward along the conveying track (the forward power is pushed by the upward pushing block fixed on the lunch box cover conveying chain) and automatically enters the upper layer of the double-layer pre-washing machine for washing and the next step; the lunch box body continues to move forward along the conveying track of the lunch box conveying device until it automatically enters the overturning and slag discharge device; the overturning and slag discharge device automatically overturns the lunch box body to pour out the food residue inside. The poured food residue is collected by a special automatic conveying line and automatically transported to the slag collection area for collection. At the same time, the lunch box that has been emptied of its residue automatically enters the lower layer of the double-layer pre-washer for washing and the next step. During the above-mentioned conveying, lid opening, and residue emptying processes (before automatic residue emptying), the fallen food residue automatically falls into the collection tray at the bottom of the equipment. If there is any food residue adhering to the conveyor track, it will be manually rinsed with water before the end of the work. The water flow and food residue will automatically flow into the collection tray at the bottom of the equipment, and the cleaning water will be discharged centrally. The residue in the collection tray is manually removed. After the pre-washing is completed, the lid and box body enter the washing machine again for cleaning to obtain a clean lid and box body.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
