Description

Technical Field

[0001] This invention relates to the field of sanitation vehicles, and more specifically, to a tipping and loading mechanism, method, and garbage truck. Background Technology

[0002] Garbage trucks in related technologies are typically equipped with a tipping and loading mechanism. This mechanism hooks onto the garbage bin at the loading position and lifts it to tip it over for loading (pouring the garbage from the bin into the truck's container). After loading, the garbage bin is lowered back to the loading position. Different garbage collection sites may require different numbers of garbage bins to be handled; therefore, the tipping and loading mechanism is usually configured with different operating modes, such as single-bin mode or double-bin mode.

[0003] In existing technologies, the working mode of the tipping and loading mechanism usually needs to be selected by manually operating the knob in the control box, which means that the garbage truck needs to frequently switch the working mode manually during the tipping and loading operation at different garbage stations. Summary of the Invention

[0004] The present invention aims to provide a tipping bucket loading mechanism, a tipping bucket loading method, and a garbage truck, which can achieve automatic switching of working modes without manual operation.

[0005] The embodiments of the present invention can be implemented as follows: In a first aspect, the present invention provides a tipping drum feeding mechanism, comprising: A bucket-tipping frame, wherein three bucket-pushing sensor modules are spaced apart along the left and right directions, and at least two bucket-hanging sensor modules are provided on the bucket-tipping frame, wherein at least one of the bucket-hanging sensor modules is located between two adjacent bucket-pushing sensor modules; A drive assembly, which is connected to the tipping frame and is used to drive the tipping frame to lift and lower; The controller is communicatively connected to three of the bucket-pushing sensor modules, at least two of the bucket-hanging sensor modules, and the drive assembly, and is used to control the drive assembly to perform different working modes according to the sensing status of the three bucket-pushing sensor modules. The working modes include single-bucket mode and dual-bucket mode.

[0006] In an optional implementation, the number of the hanging bin sensing modules is three, and each of the three pushing bin sensing modules corresponds one-to-one. Each hanging bin sensing module and the corresponding pushing bin sensing module are used to sense the same trash can.

[0007] In an optional embodiment, at least one of the push-bin sensing module and the hang-bin sensing module includes a sensing box and a limit switch. The sensing box is disposed on the bin-tipping frame, and the limit switch is disposed inside the sensing box, with the trigger portion of the limit switch extending out of the sensing box for contact sensing with the trash can.

[0008] In an optional embodiment, the limit switch is a swing-arm type limit switch, with the swing arm of the limit switch extending out of the sensing box, and a roller for contacting the trash can is provided at one end of the swing arm extending out of the sensing box.

[0009] Secondly, the present invention provides a drum-turning feeding method, based on the drum-turning feeding mechanism described in any of the foregoing embodiments, comprising: Obtain the sensing status of the three push-bucket sensing modules; The drive assembly is controlled to perform different operating modes based on the sensing status of the three bucket-pushing sensing modules; wherein the operating modes include single-bucket mode and double-bucket mode.

[0010] In an optional implementation, the step of "controlling the drive assembly to execute different operating modes based on the sensing status of the three push-barrel sensing modules" specifically includes: If the middle push-bucket sensor module senses the trash can, and the push-bucket sensor module on either side does not sense the trash can, the drive component is controlled to execute single-bucket mode. When the push-bin sensor module on either side detects a trash can, it controls the drive assembly to execute the dual-bin mode.

[0011] In an optional implementation, the step of "controlling the driving component to execute single-bucket mode" specifically includes: After the push-bin sensor module in the middle senses the trash can, it drives the tipping frame to rise and hang the trash can. If the edge of the trash can is sensed by the hanging bin sensing module, the bin tipping frame will be driven to continue to rise with the trash can to tip it over for loading. If the edge of the trash can is not detected by the hanging bin sensing module, the bin tipping frame will be driven to descend and reset.

[0012] In an optional implementation, the step of "controlling the drive component to execute the dual-bucket mode" specifically includes: Keep the tipping frame stationary until both sides of the tipping sensor module detect the trash can, then drive the tipping frame to rise and hang the trash can. If the rims of both trash cans are fully detected by the hanging bin sensing module, the bin tipping frame will be driven to continue rising with the two trash cans for tipping and loading. If the edges of both trash cans are not fully detected by the hanging bin sensing module, the bin tipping frame will be driven to descend and reset.

[0013] In an optional implementation, the step of "controlling the drive assembly to execute different operating modes based on the sensing status of the three push-barrel sensing modules" specifically includes: If the middle push-bucket sensor module senses the trash can, and the push-bucket sensor module on either side does not sense the trash can, the drive component is controlled to execute single-bucket mode. When the push-bin sensor module on one of the two sides senses a trash can, it controls the drive assembly to execute the dual-bin mode.

[0014] When the push-bin sensor module on the other side of the two sides senses a trash can, it controls the drive component to execute the three-bin mode.

[0015] Thirdly, the present invention provides a garbage truck, including the tipping and loading mechanism described in any of the foregoing embodiments.

[0016] The beneficial effects of the tipping bucket feeding mechanism, tipping bucket feeding method, and garbage truck provided in the embodiments of the present invention include: This tipping bucket loading mechanism and corresponding tipping bucket loading method uses three bucket-pushing sensor modules arranged in the left and right directions on the tipping bucket frame. Different working modes are selected and executed according to the sensing status of the three bucket-pushing sensor modules, eliminating the need for manual operation to switch modes. This can effectively reduce the burden on garbage truck operators, optimize the user experience, reduce safety accidents caused by misoperation, and ensure the operating efficiency of garbage trucks.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0026] Garbage trucks are one of the most common sanitation vehicles. They are usually equipped with a tipping mechanism to hook and lift the garbage bins at the loading position for tipping and loading.

[0027] The tipping mechanism typically includes a push-to-position sensor and a hook-to-position sensor. The push-to-position sensor detects whether the trash can has been pushed to the feeding position, while the hook-to-position sensor detects whether the trash can in the feeding position is hooked. When the push-to-position sensor detects that the trash can has reached the feeding position, the tipping mechanism starts working. The tipping frame rises a preset distance. If the hook-to-position sensor detects that the rim of the trash can is hooked, it means the hooking is successful, and the tipping frame continues to rise with the trash can for tipping and feeding. If the hook-to-position sensor does not detect that the rim of the trash can is hooked, it means the hooking has failed, and the tipping frame descends to reset.

[0028] Meanwhile, because different waste collection sites require different numbers of waste bins, the bin-tipping and loading mechanisms are typically configured with different operating modes. Currently, these mechanisms generally operate in single-bin and double-bin modes. However, existing operating modes are usually selected and executed manually by operating a knob on the control box. Before each bin-tipping and loading operation, the garbage truck operator must operate the knob according to the actual needs to select the corresponding operating mode. If a single waste bin needs to be operated, the single-bin mode is selected; if two waste bins need to be operated, the double-bin mode is selected.

[0029] This method of switching work modes relies on manual operation, has a low degree of automation, is time-consuming and labor-intensive, and places a heavy burden on the operators. Furthermore, operators may make mistakes, potentially causing safety accidents or severely impacting the efficiency of the garbage trucks.

[0030] For example, if only a single trash can needs to be operated, but the operator mistakenly selects the dual-can mode, the tipping mechanism won't move when the operator pushes one trash can to one of the loading positions and it's detected by the corresponding push-position sensor. Instead, it will wait for the next trash can to be pushed to the other loading position before it starts rising. Only when the tipping mechanism doesn't move will the operator realize the incorrect mode selection. At this point, they need to pull the trash can away from the loading position, operate the knob to select the new mode, and then push the trash can back to the loading position. This entire process wastes a lot of time and affects the garbage truck's operational efficiency.

[0031] For example, if two trash cans need to be operated, but the operator mistakenly selects the single-can mode, and the operator pushes one trash can to one of the feeding positions and it is detected by the corresponding push-can positioning sensor, the tipping frame will immediately rise. At this time, the operator, assuming that the tipping frame will not rise immediately, will be caught off guard and may be injured by the rising tipping frame, which poses a safety hazard.

[0032] To address the above issues, this invention provides a tipping and loading mechanism. This mechanism has three push-bucket positioning sensors spaced at intervals along the left and right sides of the tipping frame. Based on the sensing status of the three push-bucket sensing modules, different working modes are selected and executed, eliminating the need for manual switching. This effectively reduces the burden on garbage truck operators, minimizes safety accidents caused by misoperation, and ensures the operational efficiency of the garbage truck.

[0033] The following section will describe in detail the overall structure, working principle, and technical effects of this tipping drum feeding mechanism, with reference to the accompanying drawings.

[0034] First embodiment: Please refer to Figure 1-4 ( Figure 1 (The LR direction is the left-right direction). This embodiment of the invention provides a tipping and loading mechanism, which can be installed on a garbage truck (such as a compressed garbage truck) to hook up the garbage bin 500 in the loading position and lift it for tipping and loading.

[0035] This drum tipping and feeding mechanism includes a drum tipping frame 100, a drive assembly 400, and a controller (not shown in the figure). Three drum pushing sensor modules 200 are spaced apart along the left-right direction on the drum tipping frame 100. The drive assembly 400 is connected to the drum tipping frame 100 and is used to drive the drum tipping frame 100 to rise and fall.

[0036] The controller is simultaneously connected (e.g., electrically) to three push-bucket sensor modules 200 and drive assembly 400, and is used to control drive assembly 400 to perform different working modes according to the sensing status of the three push-bucket sensor modules 200; among which, the working modes include single-bucket mode and dual-bucket mode.

[0037] Furthermore, the bucket-flipping rack 100 is provided with multiple hook teeth and at least two bucket-hanging sensor modules 300, both of which are communicatively connected (e.g., electrically connected) to the controller. At least one bucket-hanging sensor module 300 is positioned between two adjacent bucket-pushing sensor modules 200. Specifically, in this embodiment, there are two bucket-hanging sensor modules 300: one positioned between the left-side bucket-pushing sensor module 200 and the middle bucket-pushing sensor module 200, and the other positioned on the right-side bucket-pushing sensor module 200, away from the middle bucket-pushing sensor module 200.

[0038] Furthermore, in this embodiment, the three push-bucket sensing modules 200 and the two hook-bucket sensing modules 300 are respectively disposed on the five hook teeth. That is, in this embodiment, each sensing module is attached to or supported by a hook tooth, thereby improving the compactness of the bucket tilting frame 100 structure. In other embodiments, the sensing modules may also be disposed independently of the hook teeth, for example, disposed on one side of the hook teeth or between the hook teeth.

[0039] Furthermore, in this embodiment, there are nine hanging teeth, which are respectively the first hanging tooth 111, the second hanging tooth 112, the third hanging tooth 113, the fourth hanging tooth 114, and the hanging teeth where three bucket push sensing modules 200 and two bucket hanging sensing modules 300 are located. The first hanging tooth 111, the left-side bucket push sensing module 200, the first bucket hanging sensing module 300, the second hanging tooth 112, the middle bucket push sensing module 200, the third hanging tooth 113, the right-side bucket push sensing module 200, the second bucket hanging sensing module 300, and the fourth hanging tooth 114 are arranged from left to right.

[0040] The first hook tooth 111, the left-side push-bin sensing module 200, the first hook-bin sensing module 300, and the second hook tooth 112 together correspond to the first feeding position and are used to hook the trash can 500 that has been pushed to the first feeding position. The first hook-bin sensing module 300, the second hook tooth 112, the middle push-bin sensing module 200, and the third hook tooth 113 together correspond to the second feeding position and are used to hook the trash can 500 that has been pushed to the second feeding position (that is, the trash cans sensed by the left-side push-bin sensing module 200 and the middle push-bin sensing module 200 share the first hook-bin sensing module 300, which can reduce the number of parts, improve the structural compactness of the tipping feeding mechanism, and reduce its manufacturing cost). The third hook tooth 113, the right-side push-bin sensing module 200, the second hook-bin sensing module 300, and the fourth hook tooth 114 together correspond to the third feeding position and are used to hook the trash can 500 that has been pushed to the third feeding position.

[0041] Please refer to Figure 2 and Figure 3 At least one of the push-bin sensing module 200 and the hanging-bin sensing module 300 includes a sensing box 210 and a limit switch 220. The sensing box 210 is disposed on the corresponding hanging tooth and located below the tooth 230 (i.e., the top of the hanging tooth). The limit switch 220 is disposed inside the sensing box 210, and the trigger part of the limit switch 220 extends out of the sensing box 210 for contact sensing with the trash can 500.

[0042] Furthermore, the sensing box 210 includes a box body 212 and a cover plate 214, the box body 212 and the cover plate 214 together form an installation cavity 2122, and a clearance groove 2124 is provided on the box body 212 or the cover plate 214. Limit switch 220 is disposed within mounting cavity 2122. Specifically, limit switch 220 is mounted within mounting cavity 2122 using fasteners such as screws. Specifically, limit switch 220 can adopt different structures as needed. In this embodiment, limit switch 220 is a swing arm type limit switch (the trigger part is a swing arm 222). The swing arm 222 of limit switch 220 extends out of sensing box 210 through clearance groove 2124, which is configured to allow the swing arm 222 to swing within a preset angle range.

[0043] Furthermore, to reduce damage caused by contact between the trash can 500 and the swing arm 222, in this embodiment, a roller 224 is provided at the end of the swing arm 222 extending out of the sensor box 210 for contacting the trash can 500. The roller 224 converts the sliding friction between the swing arm 222 and the trash can 500 into rolling friction, thereby effectively reducing the damage caused by friction between the two and extending the service life of the limit switch 220 and the trash can 500.

[0044] It should be noted that in other embodiments, the limit switch 220 can also be a push-button limit switch 220 (the trigger part is a button), and the button of the limit switch 220 extends out of the sensing box 210 through the recess 2124.

[0045] The sensing module uses a limit switch 220 for sensing. Since the limit switch 220 is a contact-type inductive switch, it can sense the garbage can 500 through contact, making the sensing more accurate and reducing the probability of false sensing compared to non-contact proximity switches. Furthermore, the sensing module adopts a closed structure, with the main body of the limit switch 220 located inside the sensing box 210, and only its swing arm 222 partially exposed. The sensing box 210 effectively protects the limit switch 220 from sewage, garbage, and other contaminants, further reducing the probability of false sensing and improving sensing accuracy. This ensures the normal operation of the module, thereby guaranteeing the normal operation of the garbage truck, improving work efficiency, and reducing safety accidents.

[0046] Furthermore, in this embodiment, both the push-bin sensing module 200 and the hang-bin sensing module 300 adopt the above-described structure to ensure the accuracy of the sensing. The difference between the two is that the swing arm 222 of the push-bin sensing module 200 extends out of the sensing box 210 towards the side of the trash can 500 (i.e., the side adjacent to the feeding position) to sense whether the trash can 500 has been pushed to the feeding position. The swing arm 222 of the hang-bin sensing module 300 extends out of the sensing box 210 towards the side away from the trash can 500 (i.e., the side away from the feeding position) to sense whether the rim of the trash can 500 is caught.

[0047] The tipping and feeding mechanism also includes a positioning plate for assisting in hanging the bin. Its main function is to use the positioning plate as a reference when the relevant operator pushes the garbage bin 500 to a certain feeding position, so as to ensure that the edge of the garbage bin 500 can be successfully hung, thereby improving the success rate of hanging the bin.

[0048] Further, please refer to Figure 4 In this embodiment, the drive assembly 400 includes a rocker arm 410 and a pull rod 420 connected to the tipping bucket frame 100, and a hydraulic cylinder 430 connected to the rocker arm 410. Its specific structure and working process are existing technologies and will not be described in detail here.

[0049] This invention also provides a tipping drum feeding method, which can be used in the controller of the aforementioned tipping drum feeding mechanism to control the operation of the drive component 400.

[0050] Please refer to Figure 5 This tipping drum feeding method specifically includes: Step S100: Obtain the sensing status of the three bin-pushing sensing modules 200. The three bin-pushing sensing modules 200 sense whether a trash can 500 has been pushed to the corresponding feeding position and which feeding position the trash can 500 has been pushed to, and send the sensing status to the controller.

[0051] Step S200: Based on the sensing status of the three bucket-pushing sensor modules 200, the controller controls the drive assembly 400 to execute different working modes; wherein, the working modes include single-bucket mode and double-bucket mode. After receiving the sensing status from the three bucket-pushing sensor modules 200, the controller controls the drive assembly 400 to execute the corresponding actions, thereby driving the bucket-tipping frame 100 to perform the corresponding actions to execute different working modes.

[0052] For details, please refer to Figure 6 In this embodiment, step S200 specifically includes: If the middle push-bucket sensor module 200 senses the trash can 500, and neither of the push-bucket sensor modules 200 on either side senses the trash can 500, then step S210 is executed: control the drive component 400 to execute single-bucket mode.

[0053] Further, please refer to Figure 7 Step S210 specifically includes: Step S212: After the central push-bin sensor module 200 senses the trash can 500 (see...) Figure 8 ), drive the bucket tilting frame 100 to start rising to hang the bucket (see Figure 9 When trash can 500 is pushed to the second feeding position and is sensed by the middle push-can sensor module 200 (see...) Figure 10The controller will select to execute the single bin mode. At this time, the controller controls the drive component 400 to drive the bin tipping frame 100 to rise to a preset height, and then determines whether the trash can 500 is hooked based on whether the first bin-hanging sensor module 300 is triggered.

[0054] If the first hanging bin sensor module 300 is triggered, it means that the edge of the trash can 500 has been detected by the first hanging bin sensor module 300 (i.e., the bin has been successfully hung, and the corresponding hook teeth have engaged with the edge of the trash can 500). At this time, step S214 is executed: the tipping frame 100 is driven to continue rising with the trash can 500 to tip and load the bin. After tipping and loading is completed, the tipping frame 100 is driven to descend with the trash can 500 to the second loading position so that the relevant operators can pull it away.

[0055] If the first bin-hanging sensor module 300 is not triggered, it means that the edge of the trash can 500 has not been detected by the first bin-hanging sensor module 300 (i.e., bin hanging failed, and the corresponding hook teeth did not engage with the edge of the trash can 500). In this case, the tipping frame 100 will continue to rise but will not be able to lift the trash can 500, or the trash can 500 may fall during the lifting process. Therefore, step S216 is executed: drive the tipping frame 100 to descend and reset. If the trash can 500 is not hooked, relevant operators need to intervene.

[0056] When the push-bin sensor module 200 on either side (i.e., the left or right side) senses the trash can 500, step S220 is executed: the drive component 400 is controlled to execute the dual-bin mode.

[0057] Further, please refer to Figure 11 Step S220 specifically includes: Step S222: Keep the tipping frame 100 stationary until both sides (left and right) of the bin-pushing sensor module 200 sense the trash can 500, then drive the tipping frame 100 to rise and hang the trash can. When the trash can 500 is pushed to the first feeding position and sensed by the left-side bin-pushing sensor module 200, or pushed to the third feeding position and sensed by the right-side bin-pushing sensor module 200, the controller will select to execute the dual-bin mode. At this time, the controller controls the drive component 400 to remain stationary, and the tipping frame 100 will not rise until trash cans 500 arrive at both the first and third feeding positions (see...). Figure 12 The controller will only control the drive component 400 to move when both the left and right push-bin sensor modules 200 are triggered, thereby driving the tipping bin rack 100 to rise to a preset height, and determining whether both trash cans 500 are hooked based on whether the two hanging bin sensor modules 300 are triggered at the same time.

[0058] If both bin-hanging sensor modules 300 are triggered, it means that the edges of both bins 500 have been detected by the bin-hanging sensor modules (i.e., the bins are successfully hung). At this time, step S224 is executed: the bin-tipping frame 100 is driven to continue rising with the two bins 500 for bin-tipping and loading. After bin-tipping and loading is completed, the bin-tipping frame 100 is driven to descend with the two bins 500 and return to the first loading position and the third loading position respectively, so that the relevant operators can pull them away.

[0059] If one or both of the two bin-hanging sensor modules 300 are not triggered, it indicates that not all two trash cans 500 have been detected by the bin-hanging sensor module (i.e., bin hanging has failed). In this case, step S216 is executed: the bin-tipping frame 100 is driven to descend and reset. If any trash can 500 is not hooked, relevant personnel need to intervene.

[0060] In summary, this tipping and loading mechanism and its corresponding tipping and loading method select and execute different working modes based on the sensing status of the three tipping sensor modules 200. No manual switching is required, effectively reducing the burden on garbage truck operators, minimizing safety accidents caused by misoperation, and ensuring the operational efficiency of the garbage truck. Furthermore, when the middle tipping sensor module 200 senses the garbage bin 500, it selects and executes the single-bin mode. In this case, the garbage bin 500 is hung in a relatively central position on the tipping frame 100, without excessive left or right deviation. This allows the garbage in the garbage bin 500 to be poured relatively evenly into the garbage truck's bin, resulting in a relatively even weight distribution in the bin's left and right directions. This effectively prevents uneven loading of the compression mechanism on the bin, extending its service life. The even weight distribution of the garbage in the bin's left and right directions also avoids affecting the actual loading capacity of the bin, ensuring the efficient operation of the garbage truck.

[0061] Second embodiment: Please refer to Figure 13 and Figure 14 The tipping and feeding mechanism provided in this embodiment of the invention is basically the same as the tipping and feeding mechanism provided in the first embodiment in terms of overall structure, working principle, and technical effects. The difference is that in this embodiment, the number of hanging bin sensing modules 300 is three, and each corresponds one-to-one with the three pushing bin sensing modules 200. Each hanging bin sensing module 300 and its corresponding pushing bin sensing module 200 are used to sense the same trash can 500. That is, this embodiment adds one hanging bin sensing module 300 and one hanging tooth to support the hanging bin sensing module 300 compared to the first embodiment.

[0062] In detail, in this embodiment, the first hanging tooth 111, the left-side bucket push sensing module 200, the first hanging bucket sensing module 300, the second hanging tooth 112, the middle bucket push sensing module 200, the second hanging bucket sensing module 300 (i.e., the hanging bucket sensing module 300 added relative to the first embodiment), the third hanging tooth 113, the right-side bucket push sensing module 200, the third hanging bucket sensing module 300, and the fourth hanging tooth 114 are arranged sequentially from left to right.

[0063] Furthermore, the first hook tooth 111, the left-side push-bucket sensor module 200, the first hook-bucket sensor module 300, and the second hook tooth 112 together correspond to the first feeding position and are used to hook the trash can 500 that has been pushed to the first feeding position. The second hook tooth 112, the middle push-bucket sensor module 200, the second hook-bucket sensor module 300, and the third hook tooth 113 together correspond to the second feeding position and are used to hook the trash can 500 that has been pushed to the second feeding position. The third hook tooth 113, the right-side push-bucket sensor module 200, the third hook-bucket sensor module 300, and the fourth hook tooth 114 together correspond to the third feeding position and are used to hook the trash can 500 that has been pushed to the third feeding position.

[0064] The tipping and feeding method corresponding to the tipping and feeding mechanism provided in this embodiment is basically the same as that in the first embodiment. The difference is that in the tipping and feeding method provided in this embodiment, whether the trash can 500 at the second feeding position (i.e., the trash can 500 in single-bin mode) is caught is sensed by the newly added second hook-and-sense module 300, while in the tipping and feeding method provided in the first embodiment, whether the trash can 500 at the second feeding position is caught is sensed by the first hook-and-sense module 300, and its first feeding position... Whether the trash can 500 is caught is also sensed by the first hanging bin sensing module 300. That is, in the first embodiment, the trash cans 500 at the first feeding position and the second feeding position share one hanging bin sensing module 300. However, in this embodiment, the trash cans 500 at the first feeding position and the second feeding position are sensed by two separate hanging bin sensing modules 300 (the trash can 500 at the first feeding position is sensed by the first hanging bin sensing module 300, and the trash can 500 at the second feeding position is sensed by the second hanging bin sensing module 300).

[0065] Third embodiment: Please refer to Figure 15 , Figure 16 and Figure 17The tipping and feeding mechanism provided in this embodiment of the invention is basically the same as the tipping and feeding mechanism provided in the first embodiment in terms of overall structure, working principle, and technical effects. The difference is that in this embodiment, there are three hanging bin sensing modules 300, which correspond one-to-one with three pushing bin sensing modules 200. Each hanging bin sensing module 300 and its corresponding pushing bin sensing module 200 are used to sense the same trash can 500. That is, this embodiment adds one hanging bin sensing module 300 and a hanging tooth that carries the hanging bin sensing module 300 compared to the first embodiment. Furthermore, this embodiment adds a fifth hanging tooth 115 and a sixth hanging tooth 116 on the basis of the first embodiment, that is, this embodiment adds three hanging teeth.

[0066] In detail, in this embodiment, the first hanging tooth 111, the left-side bucket push sensing module 200, the first hanging bucket sensing module 300, the second hanging tooth 112, the fifth hanging tooth 115, the middle bucket push sensing module 200, the second hanging bucket sensing module 300, the sixth hanging tooth 116, the third hanging tooth 113, the right-side bucket push sensing module 200, the third hanging bucket sensing module 300, and the fourth hanging tooth 114 are arranged from left to right.

[0067] Furthermore, the first hook tooth 111, the left-side push-bucket sensor module 200, the first hook-bucket sensor module 300, and the second hook tooth 112 all correspond to the first feeding position and are used to hook the trash can 500 that has been pushed to the first feeding position. The fifth hook tooth 115, the middle push-bucket sensor module 200, the second hook-bucket sensor module 300, and the sixth hook tooth 116 all correspond to the second feeding position and are used to hook the trash can 500 that has been pushed to the second feeding position. The third hook tooth 113, the right-side push-bucket sensor module 200, the third hook-bucket sensor module 300, and the fourth hook tooth 114 all correspond to the third feeding position and are used to hook the trash can 500 that has been pushed to the third feeding position.

[0068] The tipping feeding mechanism provided in this embodiment has a tipping feeding method that is basically the same as the tipping feeding method in the first embodiment. The difference is that, in addition to the single-barrel mode and the double-barrel mode, the tipping feeding method provided in this embodiment also has a three-barrel mode.

[0069] Accordingly, please refer to Figure 15 In this embodiment, step S200 specifically includes: If the middle push-bucket sensor module 200 senses the trash can 500, and neither of the push-bucket sensor modules 200 on either side senses the trash can 500, then step S230 is executed: control the drive component 400 to execute single-bucket mode.

[0070] Furthermore, step S230 is similar to step S210 in the first embodiment, and specifically includes: Step S232: After the central push-bin sensor module 200 senses the trash can 500, it drives the tilting frame 100 to rise and hang the trash can. When the trash can 500 is pushed to the second feeding position and sensed by the central push-bin sensor module 200, the controller will select to execute the single-bin mode (see...). Figure 16 At this time, the controller controls the drive component 400 to drive the tipping frame 100 to rise to a preset height, and then determines whether the trash can 500 is caught based on whether the second hanging bin sensor module 300 is triggered.

[0071] If the second hanging bin sensor module 300 is triggered, it means that the edge of the trash can 500 has been detected by the second hanging bin sensor module 300. At this time, step S234 is executed: the tipping frame 100 is driven to continue to rise with the trash can 500 to tip and load the trash can. After tipping and loading is completed, the tipping frame 100 then lowers the trash can 500 to the second loading position so that the relevant operators can pull it away.

[0072] If the second bin-hanging sensor module 300 is not triggered, it means that the edge of the trash can 500 is not detected by the second bin-hanging sensor module 300. In this case, step S236 is executed: the bin-tipping frame 100 is driven to descend and reset. If the trash can 500 is not hooked, it means that the bin-hanging operation has failed. At this time, relevant operators need to intervene, and it may be necessary to repeat the bin-pushing operation.

[0073] When the push-bin sensor module 200 on one of the two sides (left or right) senses the trash can 500, step S240 is executed: the drive component 400 is controlled to execute the dual-bin mode.

[0074] Furthermore, step S240 is similar to step S220 in the first embodiment, and specifically includes: Step S242: Keep the tipping frame 100 stationary until both sides (left and right) of the tipping sensor module 200 detect the trash can 500, then drive the tipping frame 100 to rise and hang the trash can. When the trash can 500 is pushed to the first feeding position and detected by the left tipping sensor module 200, or pushed to the third feeding position and detected by the right tipping sensor module 200, the controller will select to execute the dual-bucket mode. At this time, the controller controls the drive component 400 to remain stationary, and the tipping frame 100 will not rise until trash cans 500 arrive at both the first and third feeding positions (see...). Figure 17 That is, the controller will control the drive component 400 to move only when both the left and right push-bin sensor modules 200 are triggered, thereby driving the tipping bin rack 100 to rise to a preset height, and determining whether both trash cans 500 are hooked based on whether the first and third hanging bin sensor modules 300 are triggered at the same time.

[0075] If both the first and third bin-hanging sensor modules 300 are triggered, it means that the edges of both bins 500 have been detected by the bin-hanging sensor modules 300. At this time, step S244 is executed: the bin-tipping frame 100 is driven to continue rising with the two bins 500 for bin-tipping and loading. After bin-tipping and loading is completed, the bin-tipping frame 100 lowers with the two bins 500 and returns to the first loading position and the third loading position respectively, so that the relevant operators can pull them away.

[0076] If one or both of the first and third bin-hanging sensor modules 300 are not triggered, it means that the edges of both trash cans 500 are not fully detected by the bin-hanging sensor modules 300. In this case, step S216 is executed: the bin-tipping frame 100 is driven to descend and reset. If any trash can 500 is not hooked, it indicates that the bin-hanging operation has failed, and relevant personnel need to intervene. It may be necessary to repeat the bin-pushing operation.

[0077] If the push-bin sensor module 200 on the other side (left or right) senses the trash can 500, step S250 is executed: the drive assembly 400 is controlled to execute the three-bin mode. It should be noted that whether the push-bin sensor module 200 on the left or right senses the trash can 500 and executes the three-bin mode depends on the two-bin mode. If the push-bin sensor module 200 on the left senses the trash can 500 and executes the two-bin mode, then the push-bin sensor module 200 on the right senses the trash can 500 and executes the three-bin mode, and vice versa.

[0078] Further, please refer to Figure 18 Step S250 specifically includes: Step S252: Keep the tipping frame 100 stationary until all three (left, middle, and right) push-bin sensor modules 200 detect the trash can 500, then drive the tipping frame 100 to rise and hook the trash can. When the trash can 500 is pushed to the first feeding position and detected by the left push-bin sensor module 200, or pushed to the third feeding position and detected by the right push-bin sensor module 200, the controller will select to execute the three-bin mode. At this time, the controller controls the drive component 400 to remain stationary, and the tipping frame 100 will not rise until trash cans 500 have arrived at all three feeding positions (see...). Figure 19 The controller will only control the drive component 400 to move when the push-bin sensor modules 200 on the left, middle and right sides are all triggered, thereby driving the tipping bin rack 100 to rise to a preset height, and determining whether the three trash cans 500 are all hooked based on whether the three hanging bin sensor modules 300 are triggered at the same time.

[0079] If all three bin-hanging sensor modules 300 are triggered, it means that the edges of all three trash cans 500 have been detected by the bin-hanging sensor modules 300. At this time, step S254 is executed: the bin-tipping frame 100 is driven to continue rising with the three trash cans 500 for bin-tipping and loading. After bin-tipping and loading is completed, the bin-tipping frame 100 returns with the three trash cans 500 to their respective loading positions so that the relevant operators can remove them.

[0080] If more than one of the three bin-hanging sensor modules 300 is not triggered (including one not triggered, two not triggered, and all three not triggered), it means that the edges of all three trash cans 500 have not been detected by the bin-hanging sensor module 300. In this case, step S216 is executed: drive the bin-tipping frame 100 to descend and reset. If any trash can 500 is not hooked, it means that the bin-hanging operation has failed. In this case, relevant personnel need to intervene, and it may be necessary to repeat the bin-pushing operation.
