Description

Technical Field

[0001] The utility model relates to the technical field of meal tray recycling, in particular to a device for self-cleaning vegetable residues and recycling a meal tray in a dining hall and a circuit thereof. Background Art

[0002] Garbage classification has been carried out for many years. In all places of life, we must comply with the requirements of garbage classification and discard various types of garbage separately. For example, after finishing our meals in the school cafeteria, we need to dump the food residues separately into the trash can for wet garbage, and then sort and discard other garbage. In the process of dumping food, vegetable juice and residues can easily splash on ourselves and dirty our clothes. The stains left by soy sauce, chili oil, etc. in the vegetable juice are also difficult to clean, and it is easy to leave marks on clothes and affect the appearance of clothes. In addition to being easy to splash on clothes, soup and residues are also easy to splash on the ground. The soup on the ground will be repeatedly stepped on, dirtying the floor and increasing the workload of cleaning staff. Moreover, when pouring the residue, in order to get rid of some easily adhered residues, the plate will be knocked many times, which can easily damage the plate, so new plates have to be replaced, increasing expenses. In addition, disposing of kitchen waste depends on personal awareness. The food residue on some plates is not cleaned up properly, so the cleaning staff have to clean it twice and dump the residue again, which increases the burden on the cleaning staff. During peak hours, there will be a pile of plates and people queuing up.

[0003] In order to make the plate recycling more automated and efficient, many canteens now have some plate recycling systems. This recycling system allows the plates to be directly transported from the plate recycling area to the back kitchen cleaning area via a conveyor belt, eliminating the trouble of manually carrying the plates. However, most of the widely used plate recycling systems currently only use conveyor belts to transport plates, without other cleaning functions. When recycling, diners still need to dump the vegetable residues themselves and then place the plates on the conveyor belt. Therefore, the above-mentioned situation of dirtying clothes and floors will still occur, and during peak meal times, some people are slow to pour, which easily leads to crowding. Some canteens do not need to dump the vegetable residues themselves, but only need to place the plates on the conveyor belt, and the cleaning staff will dump the vegetable residues at the end of the conveyor belt. Although this method avoids dirtying the diners' clothes and the canteen floor, during peak meal times, there are too many plates and the cleaning staff will not have time to clean them up, so there will be a large number of plates piled up, which is very inconvenient and will increase the burden of cleaning. Moreover, during peak hours, there is a shortage of manpower and the dumping sites are unattended, so the trash cans may be full but not replaced in time, which may also lead to the above-mentioned problems.

[0004] In summary, after finishing a meal in the canteen, food residues need to be separated from other garbage and dumped separately. During the dumping process, splashes of juice can easily stain clothes and the canteen environment. The existing plate recycling system in most canteens can only perform a simple plate delivery function. Plates still need to be cleaned manually. During peak hours, plates are prone to pile up and people queue up, which will cause adverse effects.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the utility model, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0030] See also Figures 1 to 8. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantial changes in the technical content.

[0031] See also Figures 1 to 4 The utility model provides an integrated device for self-cleaning vegetable residues and recovering dinner plates for a canteen, comprising a box-type frame 1, a connecting bridge 2 and a bracket 22, wherein a placement opening 101 and a side opening 102 are respectively provided on the top surface and the side surface of the box-type frame 1; the connecting bridge 2 is rotatably mounted on the box-type frame 1, and a first motor 20 is mounted on the rotating connection end of the connecting bridge 2 and the box-type frame 1, and a first push rod 21 is mounted on the connecting bridge 2, and a placement plate 210 is mounted on the first push rod 21, and the placement plate 210 moves between the placement opening 101 and the inside of the box-type frame 1 through the first push rod 21; the bracket 22 is mounted on the connecting bridge 2 and is located on one side of the first push rod 21, and a second push rod 220 is also mounted on the bracket 22, and a clamping claw 221 is mounted on the second push rod 220, and the clamping claw 221 moves to the placement plate 210 through the second push rod 220.

[0032] Specifically, the entire device body is a box-type frame 1 structure, the overall structure is relatively large, its frame can be made of aluminum profiles, the shell can be made of acrylic plates, small general parts can be purchased from outside, and small non-standard parts can be made of 3D printed parts. A plate placement opening 101 is set on the top of the device, and a large opening is set on the front to put in and take out the plate and the collection bucket for vegetable residues.

[0033] Furthermore, a connecting bridge 2 is provided inside the device, i.e., in the middle of the box-type frame 1. One end of the connecting bridge 2 is connected to the first motor 20 (the first motor 20 may be a turbine motor), and the other end of the connecting bridge 2 is connected to the supporting position on the box-type frame 1. Square brackets 22 may be provided at both sides of the connecting bridge 2 to install the second push rod 220 and the clamping claw 221. Similarly, a bayonet may be provided in the middle of the connecting bridge 2 to install the first push rod 21, and the other end of the first push rod 21 may be connected to the disc, and a placement plate 210 may be provided on the disc to support the meal plate placed from the placement port 101.

[0034] Thus, in order to realize automatic cleaning of the food residue on the dinner plate, the dinner plate needs to be fixed first. Considering that the edges of the dinner plate are thin and easy to clamp, the clamping claws 221 are installed on both sides of the placement plate 210 to fix the dinner plate with the clamping claws 221. Similarly, in order to make it easier for the food residue on the dinner plate to fall into the trash can located under the box-type frame 1, the dinner plate can be tilted at a certain angle. Therefore, the first motor 20 is used to drive the clamping claws 221 to rotate, so that the dinner plate is rotated at a certain angle.

[0035] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 In one embodiment, it also includes a brush plate mechanism 3, which includes a bracket 30, a fixed plate 31 and a brush 32. The bracket 30 is mounted on the box frame 1, and a third push rod 301 is mounted on the bracket 30; the fixed plate 31 is mounted on the third push rod 301 and moves toward the connecting bridge 2 through the third push rod 301; the brush 32 is mounted on the fixed plate 31 and is transmission-connected to the second motor 310 mounted on the fixed plate 31.

[0036] Specifically, a plurality of brushes 32 for cleaning plate residues can be arranged on the side of the fixed plate 31 facing the connecting bridge 2, and the brush 32 is connected to the second motor 310 and installed on the fixed plate 31, and the fixed plate 31 is connected to the third push rod 301, and the fixed plate 31 installed with the brush 32 is installed on the box-type frame 1 through the bracket 30, and the connecting hole designed on the bracket 30 is used to install the third push rod 301, so that the rear end of the third push rod 301 is fixed on the bracket 30, and the front end is connected to the fixed plate 31 of the brush 32, so that the brush 32 is driven by the third push rod 301 to move toward the plate clamped by the clamp 221 to achieve the cleaning of the plate residue.

[0037] In this way, in order to clean the food residue on the plate, the brush 32 is rotated to clean the food residue. After cleaning, the first motor 20 drives the clamping claw 221 to deflect and rotate the plate to the other side of the brush 32, and then falls into the plate collection bucket.

[0038] See also Figure 2 , Figure 3 and Figure 5 In one embodiment, it also includes a circuit box 4, which is mounted on the box frame 1 on one side of the brush plate mechanism 3. A circuit box 4 is provided next to the brush 32 bracket 22 to install the connecting wires of the control motherboard and other components of the device.

[0039] See also Figures 2 to 5In one embodiment, two brackets 22 are respectively installed at two ends of the connecting bridge 2, and the second push rods 220 and the clamping claws 221 respectively installed on the two brackets 22 move synchronously.

[0040] Furthermore, the two brackets 22 and the connecting bridge 2 are an integrated structure and are U-shaped and located inside the box-type frame 1 , and the first push rod 21 is installed on the connecting bridge 2 at a middle position between the two brackets 22 .

[0041] Specifically, the square brackets 22 installed at the two sides of the connecting bridge 2 can be installed on one side or on both sides. By installing two clamping claws 221 on both sides, the dinner plate can be clamped more stably. Similarly, according to the two clamping claws 221 installed on both sides, the second push rods 220 and the clamping claws 221 on both sides of the connecting bridge 2 move synchronously, so that the edges of the dinner plate on the tray lifted by the first push rod 21 in the middle part of the connecting bridge 2 can be clamped synchronously, and the dinner plate can be fixed, so that the dinner plate can be thrown into the collection bucket after the dinner plate residue is processed.

[0042] See also Figures 2 to 5 In one embodiment, the connecting bridge 2 is provided with a photoelectric switch 11 below the placement plate 210 . The photoelectric switch 11 and the brush plate mechanism 3 are respectively located on both sides of the connecting bridge 2 . The placement plate 210 is provided with a notch 211 at a position corresponding to the photoelectric switch 11 .

[0043] Specifically, a sub-frame for mounting the photoelectric switch 11 is installed at the lower end of the connecting bridge 2, and the signal of the photoelectric switch 11 passes through the notch 211 through the notch 211 provided on the placement tray, thereby using the photoelectric switch 11 to detect whether a meal tray is placed on the placement tray. When the meal tray is placed, the signal of the photoelectric switch 11 changes due to the shielding of the notch 211 by the placed meal tray, and then the second push rod 220 drives the clamping claw 221 to extend to clamp the meal tray for subsequent processing steps.

[0044] Furthermore, the photoelectric switch 11 can also be used to detect whether there are obstacles in front of the set distance. When an obstacle appears within the set distance, the light emitted by the photoelectric switch 11 will be reflected back. When the reflected light is received, the signal of the photoelectric switch 11 will change, thereby realizing the obstacle determination. Using this principle, the photoelectric switch 11 can also be used to monitor the collection bucket for collecting dinner plates and vegetable residues. The set detection distance of the photoelectric switch 11 is the warning value of the amount of dinner plates and vegetable residues. When the warning value is reached, an obstacle appears within the set distance of the photoelectric switch 11, and the detected signal changes. This signal change is transmitted to the control mainboard, and the control mainboard issues a reminder by controlling the audio module and the speaker, so that the staff can replace the vegetable residue collection bucket and the dinner plate collection bucket in time.

[0045] See also Figure 3, Figure 4 and Figure 7 In one embodiment, the box-type frame 1 is provided with a proximity switch 12 on the side surface of one end of the connecting bridge 2, and the proximity switch 12 is located outside the bracket 22 on the connecting bridge 2 and is arranged around the outside of the rotating shaft of the connecting bridge 2 connecting the box-type frame 1. The proximity switch 12 and the first motor 20 are respectively located at both ends of the connecting bridge 2.

[0046] Specifically, the proximity switch 12 sensor is used to detect whether the dinner plate has been rotated to a specified angle. When the first motor 20, i.e., the turbine motor, pulls the connecting bridge 2 to rotate, the brackets 22 on both sides of the connecting bridge 2 also rotate accordingly, so the proximity switch 12 can be arranged within the rotation range of the bracket 22. When the bracket 22 rotates to the position of the proximity switch 12, the signal of the proximity switch 12 changes. In this way, the proximity switch 12 is arranged at the angle position of the bracket 22 when the dinner plate needs to be rotated, thereby realizing the monitoring of whether the dinner plate has been rotated to a specified angle.

[0047] Further, the entire working process of the device is as shown in the attached Figure 7 As shown. First, place the meal plate on the placement plate of the placement opening 101 of the box-type frame 1. At this time, the photoelectric switch 11 sensor recognizes that the meal plate has been placed, the first push rod 21 of the placement plate 210 will shrink, and the second push rod 220 of the control clamp 221 will extend, and the servo of the clamp 221 controls the clamp 221 to close and clamp the meal plate; then the turbine motor of the first motor 20 starts to work, driving the connecting bridge 2 and the meal plate clamped thereon to rotate, and the metal limit switch determines whether the meal plate has rotated to the specified angle by monitoring the metal bracket 22 at the end of the connecting bridge 2. After rotating to the specified angle, the turbine motor stops working and the meal plate is fixed at the specified angle; then the third push rod 301 at the rear end of the brush 32 will extend, so that the fixed plate 31 equipped with the brush 32 extends toward The plate is moved to the other side, and the metal limiter detects whether the plate has reached a specified angle. After the plate is rotated to the specified angle, the turbine motor stops working, and the servo motor of the clamping jaw 221 works to release the clamping jaw 221, and the plate falls into the plate collection bucket. Then the turbine motor continues to work and rotates back to the initial position, and the push rod at the plate placement position extends, the push rod of the clamping jaw 221 retracts, and the servo motor of the clamping jaw 221 works to open the clamping jaw 221 and re-grip the next plate.

[0048] More specifically, in the embodiment of the utility model, the installation steps of the integrated device for self-cleaning of vegetable residues and recycling of dining plates are as follows: first, assemble the aluminum profiles according to the designed structural model, build the box-type frame 1 structure of the device, then fix a part of the acrylic plate to the box-type frame 1 structure to form a partial shell, and then fix the bracket 30 of the brush 32 to the skeleton at the corresponding position of the box-type frame 1. Then assemble the connecting bridge 2 to the box-type frame 1 and glue it with acrylic glue. Then connect the clamping claw 221 with the second push rod 220 and install it on the bracket 22 on both sides of the connecting bridge 2, connect the supporting disc and the placing plate 210 of the dining plate with the first push rod 21 and install it on the bayonet in the middle part of the connecting bridge 2, and then connect the connecting bridge 2 to the first motor 20 and the turbine motor installed on the box-type frame 1 structure, and fix them with screws. Then, the second motor 310, i.e., the reduction motor, is connected to the fixing plate 31 of the brush 32, and the brush 32 is connected to the main shaft of the second motor 310 through a coupling, and then the fixing plate 31 of the brush 32 is connected to the third push rod 301 on the bracket 30, and the third push rod 301 is fixed to the bracket 30 by screws. Then, the photoelectric switch 11 is installed on the sub-frame of the connecting bridge 2, and the metal proximity switch 12 is installed to the corresponding position of the box-type frame 1 structure, and can be fixed with hot melt adhesive. Then, the connecting wires of the components installed on the box-type frame 1 structure are connected to the circuit of the control main board, and the control main board and other components are installed in the circuit box 4. Finally, the remaining acrylic plate is installed on the structure of the box-type frame 1 and fixed with tape, leaving only space for the placement port 101 and the side opening 102, and fixed with screws and hot melt adhesive after the device test is completed.

[0051] Specifically, in the embodiment of the utility model, the electronic components in the integrated device for self-cleaning vegetable residues and recycling plate are classified into three categories: input, control and output. The input components are used to receive information, the main controller is used to control the operation of the entire device, and the output components are responsible for performing various tasks. The control mainboard in the device can select the nano mainboard as the main controller, and the input components include the photoelectric switch 11 sensor, the metal limit switch, and the button switch. The photoelectric switch 11 sensor is used to detect whether the dinner plate is placed and whether the collection bucket for the dinner plate and vegetable residue is almost full. The metal limit switch is used to detect whether the dinner plate is rotated to a specified angle; the output components include the screen, the first push rod 21, the second push rod 220, the third push rod 301, the first motor 20, i.e., the turbine motor, the second motor 310, i.e., the reduction motor, the servo of the clamp 221, and the audio module such as MP3 and a speaker. The screen displays information about the dinner plate and kitchen waste. Each push rod is used to control the extension and retraction of the placement plate, the clamp 221, and the brush 32. The turbine motor is used to drive the dinner plate to rotate, the reduction motor is used to drive the brush 32 to rotate, the servo is used to control the opening and closing of the clamp 221, and the MP3 and speaker of the audio module are used to play reminders.

[0052] Furthermore, a circuit diagram is drawn according to the function of the device and the working principle of each component used, as shown in the attached figure. Figure 8 As shown, the entire circuit is powered by an external power supply, 5 push rods (a first push rod 21, two second push rods 220 and two third push rods 301) are connected to the digital pins D7, D8, D9, D10, D11, and D12 of the mainboard through relays, the first motor 20, i.e., the turbine motor, is connected to the digital pins D3 and D4 through the motor drive module, the three metal limit switches are respectively connected to the digital pins D0, D1, and D2, the screen is connected to the IIC interface, the second motor 310, i.e., the DC reduction motor, is connected to the analog pin A5 through a relay, the servos of the two grippers 221 are connected to the analog pin A4, the speaker is connected to the audio module MP3, the audio module is connected to the analog pins A2 and A3, and the photoelectric switch 11 is respectively connected to the analog pins A0 and A1.

[0053] In this way, various components are connected in circuit according to the drawn circuit diagram. Then the relevant function programs are set, including the initial program, clamping the plate, rotational movement, rotational cleaning, throwing the plate and restoring the original position. Specifically, the initial program: the first push rod 21 in the middle rises, the third push rod 301 at the brush 32 shrinks, the second push rod 220 of the clamp 221 shrinks, the clamp 221 opens, and all parts remain in the initial state. Clamping the plate: the first push rod 21 in the middle descends, the second push rod 220 of the clamp 221 extends, the servo of the clamp 221 rotates, and the clamp 221 closes to clamp the plate.

The dining plates are driven to the brushing mechanism by the clamping claws to automatically clean the vegetable residues on the dining plates. The dining plates are also carried by the clamping claws to collect the vegetable residues and dining plates separately at different positions. When the collection bucket for collecting dining plates or food residues is full, a reminder can be issued so that the staff can replace the collection bucket with a new one in time. This can prevent diners from soiling their clothes, the dining room floor, etc. when dumping vegetable residues, and also saves the cleaning staff the trouble of cleaning the dining plates, which is conducive to improving the efficiency of plate recycling and keeping the dining environment in the canteen clean and tidy.
