Description

Technical Field

[0001] This invention relates to a method, device, and system for dispensing mats, and particularly to a dispensing device and automatic cleaning system for use in the field of vehicle mat cleaning. Background Technology

[0002] In the applicant's previous invention patent application (202221528146.X), a method was described for distributing short vehicle seat cushions, particularly those for the front seats, individually into a dispensing device. These cushions were then automatically cleaned in a washing line. Each receiving unit of the dispensing device was straight, and the channels within each unit were short and narrow. For some pickup trucks and SUVs (off-road vehicles), where the rear seats have long cushions for two, three, or more seats connected together, this method... Figure 7 As shown, some mats have a protrusion in the center, making the dispensing device in the previous patent unsuitable for dispensing such long mats, indicating room for improvement. Furthermore, the cleaning system also needs improvement; the mats must be completely cleaned before air drying or foam cleaning is not possible during water rinsing, resulting in long cleaning times and requiring a longer conveyor line. Therefore, there is an urgent need to develop an improved dispensing device and cleaning system.

[0003] In the applicant's previous invention patent application (202210677128.6), short mats were sequentially distributed from valves in each receiving unit of a dispensing device according to the order in which they were placed by the user, and then transported to a cleaning system via a conveyor belt for cleaning. However, this application did not address the dispensing order and detection method for long vehicle mats. In the dispensing and cleaning of both short and long vehicle mats, issues regarding the dispensing order, detection order, and potential false detections need to be addressed. Furthermore, vehicle mats are generally thin, making it difficult for sensors mounted on the conveyor belt to detect them when they fall from the dispensing device. Additionally, changes in the diameter of the shafts or the spacing between shafts on the conveyor belt can lead to false detections by the sensors. Summary of the Invention

[0004] This invention is an improvement upon the applicant's previous distribution system and automatic cleaning system. The invention addresses the aforementioned challenges by providing a device for distributing different types of mats on vehicles. When different types of mats are placed into the device, it distributes them via valves to the cleaning system for a series of cleaning processes. This results in short cleaning times, a shorter required transport line, high cleaning efficiency, and the ability to simultaneously clean different types of mats.

[0005] To achieve the above objectives, the present invention provides a detection method for pad conveying, characterized in that: a sensor assembly installed on a dispensing device communicates with a control unit, and when the sensor assembly detects a pad on the conveyor line, it sends a signal wave Pwm1 with a first duty cycle of H1 to the control unit;

[0006] When there is no pad on the production line, the sensor assembly sends the detected signal wave Pwm2 with a second duty cycle of H2 to the control unit. Let the diameter of each shaft on the production line be D mm, the transmission speed of the production line be V mm / s, and the spacing between each shaft be L mm. Then, the high-level duty cycle of the signal wave Pwm2 with the second duty cycle is: The control unit compares the high-level duty cycle H1 of the signal wave Pwm1 with the high-level duty cycle H2 of the signal wave with the second duty cycle. When H1 ≥ H2, the control unit determines that the sensor assembly has detected the presence of the pad on the production line.

[0007] In this invention, the diameter of each shaft in the production line is Dmm, the transmission speed of the production line is Vmm / s, and the spacing between each shaft is Lmm. Regardless of the transmission speed of the production line, when the diameter of each shaft and the spacing between each shaft are constant, the high-level duty cycle H2 of the signal wave with the second duty cycle is constant. This is determined by the spacing between each shaft and the diameter of each shaft in the production line. When there is a pad on the production line, the sensor assembly detects that a pad is placed on the production line. The sensor assembly sends the detected signal wave Pwm1 with a first duty cycle of H1 to the control unit. To avoid the influence of the diameter and spacing of each shaft on the sensor's false detection of pads, the control unit only determines whether there is a first type of pad or a second type of pad in the production line area below the distribution device when H1 ≥ H2. This allows for accurate detection of whether a pad is placed in the production line area below the distribution device. It can solve the problem of photoelectric false detection caused by inconsistent diameters or spacings of shafts in production lines produced by different manufacturers or different batches of the same manufacturer.

[0008] In this invention, preferably, when the pad is conveyed from the assembly line in the area below the dispensing device, if sensor nine and / or sensor ten in the nonlinear channel receiving unit with a predetermined curvature of the dispensing device detects the presence of the second type of pad and the sensor assembly on the dispensing device does not detect the presence of the pad on the assembly line in the area below, then the control unit controls the opening of the second sub-valve system.

[0009] In this invention, when arranged in this way, the second type of pad allocation priority of the non-linear channel receiving unit with a predetermined curvature of the dispensing device is second only to the conveying priority when there is a first type of pad or a second type of pad on the conveyor line below the dispensing device. This avoids the situation where both the non-linear channel receiving unit with a predetermined curvature of the dispensing device has a second type of pad and there is a pad on the conveyor line below the dispensing device, resulting in confusion during simultaneous conveying, confusion during pad cleaning, and overlap of pads affecting cleaning.

[0010] In this invention, preferably, when the pad is conveyed from the assembly line in the area below the dispensing device, if sensor nine and / or sensor ten in the nonlinear channel receiving unit with a predetermined curvature of the dispensing device detects that no second type pad is present and the sensor assembly on the dispensing device does not detect that the pad is present on the assembly line in the area below the dispensing device, then if one of at least two sensors in the receiving unit with a linear channel of the dispensing device detects that the corresponding receiving unit with a linear channel has a first type pad, then the corresponding first sub-valve is opened.

[0011] In this invention, when arranged in this way, when a pad is placed in the receiving unit with the linear channel, the first type of pad placed in the receiving unit of the linear channel is allocated and conveyed with a first priority only if no pad is placed in the flow line area below the dispensing device and no second type of pad is placed in the receiving unit of the non-linear channel with a predetermined curvature. The allocation and conveying priority of the first type of pad placed in the receiving unit of the linear channel is the lowest. Setting the conveying priority of the first type of pad in the receiving unit of the linear channel to the lowest level avoids affecting the conveying of pads in the flow line area below the dispensing device and the conveying of the second type of pad in the receiving unit of the non-linear channel with a predetermined curvature. The priority setting can also prevent the pad conveying from becoming chaotic.

[0012] In this invention, preferably, once the sensor assembly detects the presence of the pad on the production line below the dispensing device, the control unit controls the opening and closing of the first sub-valve system and / or the second sub-valve system until the production line delivers the pad to the first cleaning module.

[0013] In this invention, when the device is configured in this way, the conveying priority of the pad is the highest when there is a pad on the conveyor line in the area below the dispensing device. This is because if the pad is not conveyed at the highest priority when there is a pad on the conveyor line in the area below the dispensing device, the pads will overlap and become disordered during operation. This configuration is designed to prevent this from happening.

[0014] In this invention, the sensor assembly preferably consists of two spaced-apart sensors, a sixteenth and a seventeenth, and the mat includes a first type of mat and a second type of mat. The distance between the sensor sixteenth and the sensor seventeenth is greater than the longest length of the first type of mat and less than the shortest length of the second type of mat.

[0015] In this invention, when configured in such a way, it is ensured that one of the sensors, sixteen and seventeen, can detect a signal that a first type of pad or a second type of pad is placed on the production line area below the dispensing device and send it to the control unit, thereby ensuring that the control unit can determine that a pad is placed on the production line area below the dispensing device.

[0016] This invention also relates to a dispensing device, comprising a container and a valve system. The container has a receiving space, which is provided with at least two receiving units with linear channels and at least one receiving unit with a nonlinear channel having a predetermined curvature. The type of pad dispensed by the receiving units with linear channels is different from the type of pad dispensed by the receiving unit with the predetermined curvature. A sensor assembly is installed below the container, with a sensor installed in each receiving unit with linear channels and a sensor nine and / or sensor ten installed in the nonlinear channel receiving unit with the predetermined curvature.

[0017] In this invention, a receiving unit with a linear channel is used to distribute a first type of mat from the vehicle through the valve system, while a non-linear channel receiving unit with a predetermined curvature is used to distribute a second type of mat from the vehicle through the valve system. The first and second types of mats have different shapes and sizes, thus allowing a single dispensing device to distribute different types of mats from the same vehicle or different types of mats from different vehicles. This provides strong compatibility and a wider range of applications. Different types of mats are placed into the receiving units with linear channels and the non-linear channel receiving units with predetermined curvature, respectively, and the distribution is completed through the valve system, making it simple and practical. A sensor assembly is installed below the container to detect the different types of mats placed there. Each receiving unit with a linear channel is equipped with a sensor to detect whether a first type of mat is present in the linear channel receiving unit. The non-linear channel receiving unit with predetermined curvature is equipped with sensors nine and ten, which must detect simultaneously. The simultaneous detection of both sensors ensures that the second type of mat can be detected when it is placed in the non-linear channel receiving unit with predetermined curvature, because the length of the second type of mat is greater than that of the first type of mat. When a first type of mat is placed there, sensor nine will not detect it. This allows for the detection of different types of mats and the delivery of them via a dispensing device, making it highly applicable and versatile. Alternatively, a single sensor can be placed in the center of a non-linear channel receiving unit with a predetermined curvature to achieve the same function.

[0018] In this invention, it is preferable that the receiving unit with the linear channel has an open space below it.

[0019] In this invention, when the first type of mat is contained in the receiving unit with a linear channel, the first type of mat can slide off from the first sub-valve system and fall from the open space below the receiving unit with the linear channel onto the conveyor line for conveying and cleaning. This arrangement is simple in structure and facilitates sliding, eliminating the possibility of blockage when the first type of mat slides off.

[0020] In this invention, preferably, the linear channel of the receiving unit with the linear channel extends through the nonlinear channel of the nonlinear channel receiving unit with the predetermined curvature.

[0021] In this invention, the first type of pad in the receiving unit with a linear channel can slide directly through the nonlinear channel of the nonlinear channel receiving unit with a predetermined curvature via a valve system onto the assembly line. This makes the pad slide more smoothly and prevents jamming because the pad slides almost vertically.

[0022] In this invention, preferably, a guiding and lifting device is also provided at the junction of the nonlinear channel and the linear channel.

[0023] In this invention, when the second type of mat is placed into the nonlinear channel receiving unit with a predetermined curvature, the mat will be slightly lifted during its descent due to the action of the guide lifting device, and then gradually move forward. In this way, the second type of mat can be completely placed into the valve system. The mat will not slide down from the through-channel of the linear and nonlinear channels and get stuck, so that the mat cannot be completely placed into the nonlinear channel receiving unit with the predetermined curvature.

[0024] This invention also relates to a cleaning system, including the aforementioned distribution device, and further including a production line and a cleaning chamber, wherein a first cleaning module, a foam water cleaning module and a second cleaning module are installed in the cleaning chamber.

[0025] In this invention, the dispensing device is used in the cleaning system to neatly and individually or alternately dispense different types of vehicle mats into the cleaning system. After being rinsed with clean water by the first cleaning module in the cleaning chamber on the assembly line, deeply cleaned by the foam water cleaning module, and then cleaned again by the second cleaning module spraying clean water to remove foam and dirt, the mats are automatically cleaned and become more tidy. The cleaning efficiency is high, and water does not splash outside. Attached Figure Description

[0050] The embodiments described herein are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Rather, the embodiments selected for description are chosen to enable those skilled in the art to practice the invention. Although this disclosure is described in conjunction with mats used in vehicles, it should be understood that other types of mats, such as carpets, may be used. The mats present on the assembly line below the dispensing device in this application refer to either the first type 1 mat or the second type 2 mat mentioned below, and the sensor assembly mounted on the dispensing device refers to a single sensor or two sensors spaced apart, or a sensor array.

[0051] See Figure 1 and Figure 2 The assembly line 100 is specifically a mesh chain shaft assembly line, including wire mesh 102 and shafts 101. Let the diameter of each shaft of the assembly line 100 be D mm, the transmission speed of the assembly line 100 be V mm / s, the interval between each shaft 101 be L mm, the diameter of the wire mesh be d mm, the shafts 101 be arranged at equal intervals, and the wire mesh 102 be wound around the shafts 101.

[0052] See Figure 6 and Figure 7 The image shows a vehicle mat of type 1 and type 2. Type 1 mat is shorter in length and width, while type 2 mat is longer in length and width. The length of type 1 mat is l, and the length of type 2 mat is L. The maximum length of type 1 mat is lmax, and the minimum length of type 2 mat is Lmin. Typically, the length L of type 2 mat is between 1 and 1.5 m, while the length l of type 1 mat is between 0.5 and 1 m, with L > l. Type 2 mat 2 has a protrusion 201 in the center, and its cross-section is usually rectangular or trapezoidal. It is generally used for installation on the rear seats of vehicles.

[0053] The first type of mat 1 or the second type of mat 2 can be placed on the production line 100, with the dispensing device mounted above the production line 1. Alternatively, the first type of mat 1 or the second type of mat 2 can be placed on the production line 100 below the dispensing device. See [link / reference]. Figure 2 This shows that the first type of mat 2 is placed on production line 1.

[0054] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 12 and Figure 24 The sensor assembly installed on the dispensing device communicates with the control unit. The sensor assembly is preferably sensor sixteen B16 and sensor seventeen B17. When either sensor sixteen B16 or sensor seventeen B17 detects a first type of pad 1 or a second type of pad 2 on the production line 100, it sends a signal wave Pwm1 with a first duty cycle of H1 to the control unit. When neither the first type of pad 1 nor the second type of pad 2 is present on the production line 100, sensor sixteen B16 or sensor seventeen B17 sends a detected signal wave Pwm2 with a second duty cycle of H2 to the control unit. The production line 100... The diameter of each shaft is Dmm, the transmission speed of the assembly line 100 is Vmm / s, and the spacing between each shaft is Lmm. Then, the high-level duty cycle of the signal wave with the second duty cycle is: The control unit compares the high-level duty cycle H1 of the signal wave Pwm1 with the high-level duty cycle H2 of the signal wave with the second duty cycle. When the control unit detects that H1 > H2, the control unit determines that the sensor sixteen B16 or the sensor seventeen B17 has detected that the assembly line has the first type of pad 1 or the second type of pad 2. When H1 = H2, it can also be detected, but this situation rarely occurs.

[0055] Regardless of whether the transmission speed of the assembly line is fast or slow, the high-level duty cycle of the signal wave with a second duty cycle H2 is constant, which is determined by the spacing between each shaft rod and the diameter of each shaft rod. When there is a mat on the assembly line 100, one of the sensor sixteen B16 and the sensor seventeen B17 detects that a mat is placed on the assembly line 100, and the sensor sixteen B16 or the sensor seventeen B17 sends the detected signal wave Pwm1 with a first duty cycle H1 to the control unit. In order to avoid the influence of the diameter of each shaft rod and the spacing between each shaft rod on the sensor's false detection of the mat, only when the control unit determines that H1 > H2, the control unit finally determines that there is a mat on the assembly line area below the distribution device, which can accurately detect that a mat is placed on the area of the assembly line 100 below the distribution device. Of course, the use of one sensor can also detect that a mat is placed on the assembly line area below the distribution device, and can also achieve the same function. This can also solve the problem of false photoelectric detection caused by inconsistent diameters of shaft rods or inconsistent spacing between shaft rods of assembly lines produced by different manufacturers or different batches of the same manufacturer.

[0056] The sensor sixteen B16 and the sensor seventeen B17 are installed on the bottom housing of the distribution device, preferably installed in the middle area of the bottom housing, and fixedly installed on the protruding part of the bottom housing with screws or bolts. The straight-line distance between the sensor sixteen B16 and the sensor seventeen B17 is K, lmax < K < Lmin, and the connecting line between them is parallel to the assembly line 100. This can ensure that one of the sensor sixteen B16 and the sensor seventeen B17 can detect the signal of the first type mat 1 or the second type mat 2 placed on the area of the assembly line 100 below the distribution device and send it to the control unit, and finally ensure that the control unit can determine that the first type mat 1 or the second type mat 2 is placed on the assembly line area below the distribution device. The sensor sixteen B16 and the sensor seventeen B17 preferably adopt scattering photoelectric sensors, which emit light with a certain scattering gap and then return to the receiver. Compared with a point-shaped vertical linear photoelectric sensor, when the shortest mat appears, any one of the sensor sixteen B16 and the sensor seventeen B17 can also detect it. Preferably, the scattering gap between the scattering photoelectric sensors is greater than the diameter d mm of the wire mesh, so that when no mat is placed on the area of the assembly line 100 below the distribution device, the influence of the wire mesh on the detection of the sensor sixteen B16 and the sensor seventeen B17 can be filtered out, and then the sensor sixteen B16 and the sensor seventeen B17 are only affected by each shaft rod of the assembly line. Alternatively, a sensor array formed by a plurality of sensors can be used.

[0057] See Figure 3 , 45. When there is no pad placed on the conveyor line 100 area below the distribution device, the high-level pulse in the level pulse diagram detected by sensor sixteen B16 and sensor seventeen B17 is shorter when the conveying speed of the conveyor line 100 is slow. When the conveying speed of the conveyor line 100 is slow, the high-level pulse in the level pulse diagram is even shorter, but the duty cycle of the high-level pulse in one cycle will not change. When a pad is placed on the assembly line 100 area below the distribution device, the output is basically a straight line of high-level pulses. This is because the pad basically blocks the photoelectric sensor. The sensor detects a high-level signal, and the duty cycle per unit time is 100%. Since L is several times or tens of times larger than D, this ensures that the signal wave Pwm1 of the first duty cycle is greater than the signal wave Pwm2 of the second duty cycle, i.e., H1 > H2. The control unit determines that a pad is present, thus avoiding the influence of the diameter and spacing of the shafts 101 of the assembly line 100 on the detection of the pad.

[0058] Continue reading Figure 10 , 16 17, 20, 21, and 22, when the pads begin to be conveyed from the assembly line 100 in the area below the dispensing device, if sensors 9B9 and 10B10 in the non-linear channel receiving unit 32 with a predetermined curvature of the dispensing device detect the presence of a second type of pad 2, while sensors 16B16 and 17B17 on the dispensing device do not detect any pads on the assembly line 100 in the area below, the control unit controls the opening of the second sub-valve system 42. In this configuration, the second type of pad 2 in the non-linear channel receiving unit 32 with a predetermined curvature of the dispensing device has a dispensing priority level second only to the conveying priority of the pads 2 on the assembly line 100 below the dispensing device. This avoids the situation where both the non-linear channel receiving unit 32 with a predetermined curvature and the assembly line 100 below the dispensing device have pads, leading to confusion during simultaneous conveying, pad cleaning chaos, and pad overlap affecting cleaning. Of course, it is also possible to detect the second type of pad 2 placed in the nonlinear channel receiving unit 32 with a predetermined curvature by using a sensor. In this case, the sensor should preferably be placed in the middle of the nonlinear channel receiving unit 32 with a predetermined curvature, so that the same function can be achieved.

[0059] When the pads begin to be conveyed from the flow line 100 in the area below the dispensing device, if neither sensor 9B9 nor sensor 10B10 in the nonlinear channel receiving unit 32 with a predetermined curvature of the dispensing device detects the second type of pad 2, and neither sensor 16B16 nor sensor 17B17 on the dispensing device detects that a pad is placed on the flow line 100 in the area below, then if at least two sensors in the receiving unit with a linear channel of the dispensing device detect that the corresponding receiving unit 31 with a linear channel has the first type of pad, then the first sub-valve 4101 in the corresponding first sub-valve system 41 is opened. When a pad is placed in the linear channel receiving unit 31, the pad placed in the linear channel receiving unit 31 will be distributed and conveyed only if neither the first type of pad 1 nor the second type of pad 2 is placed in the area of ​​the flow line 100 below the dispensing device, nor if neither the second type of pad 2 is placed in the non-linear channel receiving unit 32 with a predetermined curvature. The distribution and conveying level of the pad placed in the linear channel receiving unit 31 is the lowest. Setting the pad conveying level to the lowest level avoids affecting the conveying of the pads placed in the area of ​​the flow line 100 below the dispensing device and the conveying of the second type of pad in the non-linear channel receiving unit 32 with a predetermined curvature. The priority setting can also prevent conveying chaos from occurring.

[0060] Once one of the sensors, 16B16 and / or 17B17, detects a pad placed on the conveyor line 100 below the dispensing device, the control unit will not control the opening and closing of the first sub-valve system 41 and the second sub-valve system 42 until the conveyor line 100 delivers either the first type of pad 1 or the second type of pad 2 to the first cleaning module 908. When a pad is present on the conveyor line 100 in the area below the dispensing device, the conveying priority of that pad is the highest. This is because if the conveying priority of a pad is not the highest when it is present on the conveyor line in the area below the dispensing device, then when the conveyor line 100 delivers the first type of pad in the linear channel receiving unit 31 or the second type of pad in the nonlinear channel receiving unit 32 with a predetermined curvature, there is a high probability of pad overlap and disorder. This setting is to prevent this from happening. This also has another advantage: regardless of the speed of the conveyor line 100, pad overlap and disorder will not occur.

[0061] Furthermore, when the conveyor line 100 begins conveying either type 1 or type 2 mats from the distribution device, the control unit can control the opening and closing of the first sub-valve system 41 and the second sub-valve system 42. This saves conveying time and improves cleaning efficiency; the saved time is the conveying time of the mats being transported to the cleaning module. When the conveyor line 100 in the cleaning system 1000 has a faster conveying speed, the control unit can control the interval between the next mat and the previous mat, setting the interval to be shorter. Conversely, when the conveyor line speed in the cleaning system is slower, the control unit can control the interval between the next mat and the previous mat, setting the interval to be longer. This adapts to different conveying speeds in the cleaning system's conveyor line under different conditions. The interval time can also be adjusted via the control unit's backend settings, ranging from 0.1 seconds to 100 seconds.

[0062] Sensor 9 B9 is installed in the upper part of the channel of the nonlinear channel receiving unit 32 with a predetermined curvature, and sensor 10 B10 is installed in the lower part. Since the second type of pad 2 is longer, and the channel of the nonlinear channel receiving unit 32 is also long, simultaneous detection by both sensors ensures that the second type of pad 2 is placed correctly and detected. This is because with only one sensor, for example, if the sensor is only installed in the upper or lower part of the channel of the nonlinear channel receiving unit 32, although the second type of pad 2 may be placed, it may not be in the correct position, or it may be in the correct position but not detected. The vertical arrangement of the two sensors avoids this problem. Alternatively, only one sensor can be used, placed in the middle of the nonlinear channel of the nonlinear channel receiving unit 32 with a predetermined curvature, achieving the same function.

[0063] See Figure 16 , Figure 17 and Figure 18In this embodiment, the dispensing device has one nonlinear channel receiving unit 32 with a predetermined curvature and eight linear channel receiving units 31. Sensors B1, B2, B3, B4, B5, B6, B7, and B8 are installed from right to left in the eight linear channel receiving units 31. Eight indicator lights are installed next to the entrances of the eight linear channel receiving units 31, from right to left: Indicator Light D1, Indicator Light D2, Indicator Light D3, Indicator Light D4, Indicator Light D5, Indicator Light D6, Indicator Light D7, Indicator Light D8, Indicator Light D9, Indicator Light D1, Indicator Light D2, Indicator Light D1, Indicator Light D2, Indicator Light D3 ...4, Indicator Light D1, Indicator Light D2, Indicator Light D3, Indicator Light D4, Indicator Light D1, Indicator Light D2, Indicator Light D3, Indicator Light D4, Indicator Light D1, Indicator Light D2, Indicator Light D3, Indicator Light D4, Indicator Light D1, Indicator Light D2, Indicator Light D3, Indicator Light D4, Indicator Light D1, Indicator Light D2, Indicator Light D3 3. Indicator lights D4, D5, D6, D7, and D8 are installed next to the entrance of the nonlinear channel receiving unit 32 with a predetermined curvature. Indicator light D9 is installed next to the entrance of the nonlinear channel receiving unit 32 with a predetermined curvature. Below the receiving unit 31 with eight linear channels, there are eight valves from right to left, namely the first sub-valve A1, the second sub-valve A2, the third sub-valve A3, the fourth sub-valve A4, the fifth sub-valve A5, the sixth sub-valve A6, the seventh sub-valve A7, and the eighth sub-valve A8. The second sub-valve A9 is also installed below the nonlinear channel receiving unit 32 with a predetermined curvature.

[0064] See Figure 13 , 14 And 15, the first sub-valve A1, the second sub-valve A2, the third sub-valve A3, the fourth sub-valve A4, the fifth sub-valve A5, the sixth sub-valve A6, the seventh sub-valve A7, the eighth sub-valve A8, and the second sub-valve A9 of the nine valves are respectively connected to nine pneumatic drive devices 5 through motion mechanism 40. See again Figure 17 and Figure 18 Nine pneumatic power drive devices 5 are connected to nine electrically operated valves via pipelines. From right to left, they are electrically operated valve 9 C9, electrically operated valve 1 C1, electrically operated valve 2 C2, electrically operated valve 3 C3, electrically operated valve 4 C4, electrically operated valve 5 C5, electrically operated valve 6 C6, electrically operated valve 7 C7, and electrically operated valve 8 C8.

[0065] See Figure 8 , Figure 9 and Figure 24The control unit also includes a memory that stores a correspondence table between sensors, first sub-valves, second sub-valves, electrically operated valves, and indicator lights. Specifically, it stores a one-to-one correspondence table between first sub-valve A1, sensor B1, electrically operated valve C1, and indicator light D1; second sub-valve A2, sensor B2, electrically operated valve C2, and indicator light D2; ..., second sub-valve A9, sensor B9, and sensor B10, electrically operated valve C9, and indicator light D9. Nine detectors are connected to the control unit via nine signal lines. When the user places the second type of mat 2 into the non-linear channel receiving unit 32 with a predetermined curvature in the dispensing device (e.g., receiving unit B1), and the detectors in the receiving unit detect the mat being placed, sensors B9 and B10 detect the presence of the second type of mat 2. The control unit then controls indicator light D9 to illuminate, indicating that the second type of mat 2 is ready for cleaning, i.e., the second sub-valve A9 is ready to open. The control unit then sends a queuing signal to the receiving unit 32. Information is sent to the storage unit; when the user places the first type of mat 1 into the receiving unit 31 with a linear channel in the dispensing device, such as the receiving unit corresponding to the second sub-valve A2, and then the sensor B2 in the receiving unit detects that the first type of mat 1 has been placed and is in place, the control unit receives the instruction that the first type of mat 1 is waiting to be cleaned, and sends the queuing information of the first type of mat 1 in the corresponding channel of the receiving unit 31 to the storage unit, and at the same time the corresponding indicator light D2 lights up; in this way, after all the mats have been placed, the storage unit stores the queuing information of all the mats. The control unit, according to the correspondence between the sensor-first sub-valve-second sub-valve-electrically operated valve-indicator light stored in the memory, and then according to the set conveying priority level of the first type of mat 1 or the second type of mat 2 in the area of ​​the conveyor line 100 below the dispensing device as first, the conveying priority level of the second type of mat 2 placed in the non-linear channel receiving unit 32 with a predetermined curvature as second, and the conveying priority level of the first type of mat 1 placed in the receiving unit 31 with a linear channel as third. After the user has placed all the mats, press the start button. Then, according to the sequence and time of the commands sent by the sensors one to eight in the linear channel receiving unit to the control unit, the corresponding electric operating valves are controlled to open in sequence according to the correspondence between the light-receiving unit-valve-electrically operated valve-detector stored in the storage unit.

[0066] Because the control unit's memory stores at least the correspondence information of valves, sensors, and electrically operated valves, the control unit can execute the instruction to allocate the mats in sequence based on the received instruction to queue the mats for cleaning. Cleaning the mats involves allocating them, which requires opening the corresponding valves. Opening the corresponding valves requires closing the corresponding electrically operated valves. The electrically operated valves themselves do not indicate that they correspond to specific valves; only when the control unit's memory stores the correspondence information of valves, detectors, electrically operated valves, receiving units, and indicator lights can the control unit open the corresponding valves sequentially according to the order in which the mats are placed. By storing the correspondence information, the control unit can easily identify the correct order, making control more accurate and convenient. For the specific allocation of the first type of mat 1 in the linear channel receiving unit, please refer to the inventor's previous invention patent application 202210677128.6, the entire contents of which are incorporated herein by reference.

[0067] This invention application also relates to a dispensing device, including a container 3 and a valve system 4. The container 3 has a receiving space, which is provided with at least two receiving units 31 with linear channels 3101 and at least one nonlinear channel receiving unit 32 with a predetermined curvature. The type of pad dispensed by the receiving unit 31 with linear channels 3101 is different from the type of pad dispensed by the nonlinear channel receiving unit 32 with the predetermined curvature. Sensors sixteen B16 and seventeen B17 are installed below the container 3. Each receiving unit 31 with linear channels 3101 is equipped with a sensor, and the nonlinear channel receiving unit 32 with the predetermined curvature is equipped with sensors nine B9 and ten B10. The receiving unit 31 with a linear channel 3101 is used to distribute the first type of mat 1 of the vehicle through the valve system 4, and the non-linear channel receiving unit 32 with a predetermined curvature is used to distribute the second type of mat 2 of the vehicle through the valve system 4. The first type of mat 1 and the second type of mat 2 have different shapes and sizes, so that different types of mats in the same vehicle or different types of mats in different vehicles can be distributed with one dispensing device. It has strong compatibility and a wider range of applications. Different types of mats are placed into the receiving unit 31 with a linear channel and the receiving unit 32 with a predetermined curvature respectively, and the distribution can be completed through the valve system 4. It is simple and practical. Sensors 16B16 and 17B17 are installed below the container 3 to detect whether the conveyor below contains either the first type of pad or the second type 2. Sensors installed in each linear channel receiving unit 31 can detect whether a pad is present in the linear channel receiving unit. Sensors 9B9 and 10B10, installed in the non-linear channel receiving unit with a predetermined curvature, must detect simultaneously. Simultaneous detection by both sensors ensures that the second type of pad 2 can be detected when placed in the non-linear channel receiving unit 32 with the predetermined curvature, because the length of the second type of pad 2 is greater than the length of the first type of pad 1. If the first type of pad 1 is placed, it will not be detected. This allows for the detection of different types of pads and the completion of conveying via a distribution device, offering strong applicability and wide versatility.

[0068] The first type of pad 1 can be dispensed from the first sub-valve system 41, and the second type of pad 2 can be dispensed from the second sub-valve system 42. This allows for the second sub-valve system 42 to be opened first to dispense the second type of pad 2 from the non-linear channel receiving unit 32 with a predetermined curvature, followed by the first sub-valve system 41 to be opened to dispense the first type of pad 1 from the receiving unit with the linear channel 3101. This convenient control avoids overlap or blockage caused by the simultaneous dispensing of two different types of pads, preventing subsequent cleaning chaos. The first sub-valve system 41 is mounted on the support frame 4103, allowing for quick and easy installation. The support frame 4103 can be directly installed below the container 3 to secure the first sub-valve system. See also... Figure 3 The dispensing device for dispensing mats is supported on the support frame 20. The dispensing device 3 can be placed above the production line via the support frame 20. The base of the support frame can also be equipped with casters, which can be used to push the dispensing device forward and place it above the production line with minimal effort.

[0069] The receiving unit 31 with linear channel 3101 has an open space 11 below it. When the first type of pad 1 is received in the receiving unit 31 with linear channel 3101, the first type of pad 1 can slide out from the first sub-valve system 31 and then slide down from the open space 11 below the receiving unit 31 with linear channel to fall onto the conveyor line 100 for cleaning. This arrangement is simple in structure, facilitates sliding, and eliminates the possibility of blockage when the first type of pad 1 slides down.

[0070] See Figures 12 to 14At least one first sub-valve 4101 also includes a guide 4104, which is integrally formed with the first sub-valve 4101. When the first sub-valve 4101 swings open from top to bottom, it can restrict the lateral movement of the pads sliding off the first sub-valve 4101. The first sub-valve 4101 itself can also be limited vertically. The first sub-valve 4101 and the guide 4104, whether modified or not, together form a slide-like structure. When the first type of pad 1 (short pad) slides off the first sub-valve 4101 and falls into the cleaning system 1000, the first type of pad 1 (short pad) can be arranged neatly without disorder. The container 3 is provided with multiple (more than two) receiving units 31 with linear channels 3101. The multiple receiving units 31 with linear channels 3101 are matched with the first sub-valve 4101, and the number of multiple receiving units 31 with linear channels 3101 is equal to the number of the first sub-valve 4101. The first type of vehicle mat 1 can be placed in each receiving unit 3 with a linear channel 3101 in the container 3. Each receiving unit 31 with a linear channel 3101 holds one first type of vehicle mat 1. The sliding of each mat can be controlled individually by controlling the first sub-valve 4101. Each receiving unit 3 with a linear channel 3101 in the container 3 not only serves to contain and support the mat, but also guides and assists in the sliding of the vehicle mat. Each receiving unit 3 with a linear channel 3101 is formed between partition walls, and the angle between the partition walls and the horizontal plane is between 5-15°, preferably 10°. In this way, the partition walls support the vehicle mat 12, and when the first sub-valve 4101 is opened, the vehicle mat can also slide down along the partition walls.

[0071] See Figure 17 This shows that the electrically operated valve of the gas delivery device of the pneumatic drive unit 5 is open, while the first sub-valve system 41 and the second sub-valve system 42 are closed. (See also...) Figure 18The diagram shows the pneumatic drive unit 5 with its gas delivery device electrically operated valve closed, each first sub-valve 4101 of the first sub-valve system 41 swung downwards in an open state, and at least one second sub-valve 4204 of the second sub-valve system 42 moved downwards. The gas delivery device includes multiple electrically operated valves, a gas distribution unit 50, and a gas generating device. The gas generating device is connected to the gas distribution unit via a delivery pipe. The gas distribution unit distributes the gas into multiple streams, which are then connected to the gas pipes of the pneumatic drive unit 5 via multiple pipelines. In this embodiment, the gas generating device 50 can specifically be an air pump or a gas compressor, and the gas distribution unit is preferably a multi-way valve. The gas generated by the gas generating device 50 is distributed by the gas distribution unit and transported through multiple pipelines to the gas pipes of multiple first sub-valves 4101 and second sub-valves 4204 in the first sub-valve system 41 and the second sub-valve system 42. There are 9 electrically operated valves, which is equal to the total number of multiple first sub-valves 4101 and second sub-valves 4204, including electrically operated valve one C1, electrically operated valve two C2, electrically operated valve three C3, electrically operated valve four C4, electrically operated valve five C5, electrically operated valve six C6, electrically operated valve seven C7, electrically operated valve eight C8 and electrically operated valve nine C9. The number of pipelines is equal to the number of electrically operated valves and the total number of valves. In this embodiment, 9 pipelines are used. Figure 10 This is a top view of the distribution device. Vehicle mats are placed from top to bottom into the receiving units through placement inlet 14. There are eight receiving units 31 with linear channels 3101 and one non-linear channel receiving unit 32 with a predetermined curvature, the number of which is equal to the total number of valves. (See reference...) Figure 24 The gas generating device, gas distribution unit, and electrically operated valve are electrically connected to and communicate with the control unit. The control unit controls whether the gas device is pneumatic. Gas is distributed by the control unit and passes through the electrically operated valve, which in turn drives the valve to open or close via the pneumatic power drive device 5. The specific function of the pneumatic power drive device 5 will not be elaborated here; please refer to the technical solution in the inventor's previous utility model patent application 202221528146.X for details.

[0072] This invention also relates to a cleaning system 1000, including a dispensing device, a production line 100, and a cleaning chamber 9. The cleaning chamber 9 is equipped with a first cleaning module 908, a foam water cleaning module 909, and a second cleaning module 910. Using the dispensing device in the cleaning system allows for the orderly, individual, or alternating dispensing of different types of vehicle mats into the system. After being rinsed with clean water by the first cleaning module 908 in the cleaning chamber 9 on the production line 100, deeply cleaned by the foam water cleaning module 909, and further cleaned by the second cleaning module 910 spraying clean water to remove foam and dirt, the mats are automatically cleaned and tidier. The cleaning efficiency is high. The production line 100 specifically adopts a mesh chain shaft production line. The first type of mat 1 and the second type of mat 2, distributed from the distribution device, are conveyed by the conveyor line 100 and sequentially pass through the first cleaning module 908, where the surface of the mat is moistened by spraying clean water or simply rinsed to remove sand. Then, they pass through the foam water cleaning module 909 for a thorough deep cleaning, removing dirt, lint, and hair. Next, they pass through the second cleaning module 910, where clean water is sprayed to rinse away the foam. Finally, the mats pass through the air drying module, where hot air is blown out to dry them. The distance L1 between the first cleaning module 908 and the foam water cleaning module 909 is less than the minimum length L2 of the first type of mat 1. In this way, when the mat is conveyed between the first cleaning module 908 and the foam water cleaning module 909 at a certain speed, part of the mat being rinsed with clean water can enter the foam water cleaning module 909 for deep cleaning while the other part is still being rinsed. This can shorten the cleaning time. The distance between other modules can also be set in this way to further shorten the cleaning time and the cleaning production line. The time saved by this cleaning method is at least half of the time between when the first cleaning module 908 finishes cleaning and when the mat enters the next module. The length of the production line is reduced from the original 3-4 meters to 1.5 meters.

[0073] The cleaning chamber 9 can also include an aromatherapy module. After the mats are dried by hot air, they undergo sterilization and disinfection by the sterilization module and deodorization by the aromatherapy module. The mats placed in the car have a pleasant fragrance, providing a comfortable experience. The mats are thoroughly sterilized, preventing bacterial growth and ensuring fresh air inside the car, promoting relaxation. It is conceivable that the first cleaning module 908, the foam water cleaning module 909, and the second cleaning module 910 can be installed outside the cleaning chamber, while the blower drying module 911, the sterilization and disinfection module 912, and the aromatherapy module can be integrated inside the cleaning chamber 9. Preferably, the conveyor line 100 is slightly angled to the ground, within 1-5°. This allows water to flow slowly backward as the mats are conveyed and cleaned on the line, preventing it from flowing into the cleaning chamber 9 and causing excessive moisture that could affect the blower drying effect. The cleaning nozzles have a certain angle of inclination with the mats, preferably 45°, but can be within 30°-75°, spraying water in a cone-shaped area, reducing the number of nozzles and avoiding splashing. The first cleaning module 908, the foam water cleaning module 909, the second cleaning module 910, and the air drying module 911 can all be integrated and installed inside the cleaning chamber 9. When arranged in this way, a fog-proof curtain 906 is installed on the second cleaning module 910 and the air drying module 911. The fog-proof curtain 906 prevents the water mist generated during cleaning in the first cleaning module 908, the foam water cleaning module 909, and the second cleaning module 910 from entering the air drying module 911 and affecting the air drying effect. A dehumidifier can also be installed inside the cleaning chamber 9 to remove moisture and mist, further improving the air drying effect. The cleaning chamber 9 also includes a top cover 905, a clearance space 903, and a door 904. The top cover 905 and door 904 are hinged to the chamber frame 901. The door 904 can be opened to observe the cleaning and drying process inside. When closed, the door can be made transparent, allowing for continued observation. The top cover 905 and door 904 can be opened simultaneously, facilitating repair and replacement of any damaged modules. The air-drying module 911, sterilization module 912, first cleaning module 908, foam water cleaning module 909, and second cleaning module 910 can also be integrated into the cleaning chamber 9. The cleaning chamber 9 can also have a tilt angle of approximately 1-10°, specifically 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, or 10°, to facilitate wastewater flow to one side of the cleaning chamber 9 during the cleaning process, making wastewater collection easier. A tilt towards the feed side is preferred to prevent wet water from entering the drying chamber and improve drying efficiency.

[0074] Prioritized, sensor 11B11 is installed on the first cleaning module 908, sensor 12B12 is installed on the foam water cleaning module 909, and sensor 13B13 is installed on the second cleaning module 910. The former is correct, but the following modules and sensors do not correspond to the images and need to be modified. The system is missing module 911 and sensor B16. Module 911 (equipped with sensor 14 B14), module 912 (equipped with sensor 15 B15), and module 913 (equipped with sensor 18 B18) are also missing. (Module 913 and sensor 16 B18 are not shown in the diagram.) When mat 1 (type 1) or mat 2 (type 2) passes sequentially through module 908 (first cleaning), module 909 (foam water cleaning), module 910 (second cleaning), module 911 (drying), module 912 (sterilization), and module 913 (aromatherapy), the corresponding sensors 11 B11, 12 B12, 13 B13, 14 B14, 15 B15, and 18 B18 on each module detect mat 1 or mat 2. The controller then sequentially activates the corresponding modules for intelligent detection and control. The control logic of the cleaning system 1000 will not be elaborated further; please refer to the previous patent application 202221528146.X for details.

[0075] As another alternative embodiment of the container 3 in the dispensing device, see Figure 23 The linear channel 3101 of the receiving unit 31 with linear channel 3101 passes through the nonlinear channel 3201 of the nonlinear channel receiving unit 32 with a predetermined curvature. The first type of pad 1 in the receiving unit 31 with linear channel 3101 can slide directly through the nonlinear channel 3201 of the nonlinear channel receiving unit 32 with a predetermined curvature and fall onto the assembly line via the valve system 4. This makes the pad slide more smoothly and prevents jamming because the pad slides almost vertically. A guide lifting device 13 is also provided at the junction of the nonlinear channel 3201 and the linear channel 3101. The guide lifting device 13 is arranged on the nonlinear channel 3201 and has a guide section 1301 and a transition section 1302. Through the guiding and lifting action of the guide section 1301 and the transition section 1302, when the second type of pad 2 is placed into the nonlinear channel receiving unit 32 with a predetermined curvature, the pad will be slightly lifted due to the action of the guide lifting device. Although the pad 14 is flexible, a very short section of the pad 14 is still tough. The pad gradually moves forward, so that the second type of pad 2 can be completely placed into the valve system 4. The pad will not slide down from the through channel 12 of the linear channel 31 and the nonlinear channel 32 and get stuck, so that the pad cannot be completely placed into the nonlinear channel receiving unit 32 with a predetermined curvature.

[0076] In alternative implementations, in the first and second embodiments, the openings of the receiving unit 31 with a linear channel 3101 and the nonlinear channel receiving unit 32 with a predetermined curvature of the container 3 can be located at the front. Unlike the aforementioned embodiment where the mat is placed from top to bottom, the vehicle mat can be placed from the front to the back. This allows shorter individuals to easily place the mat 12 into the receiving unit of the container without using steps. The angle of the receiving unit can be slightly tilted backward, making it easier for the mat to fit into the receiving unit 31 with the linear channel 3101 and the nonlinear channel receiving unit 32 with the predetermined curvature. However, this does not negate the inconvenience of the aforementioned method of placing the mat, because in the aforementioned container, when the mat is placed from top to bottom, the height of the top of the container from the ground will not exceed 1500mm, making it easy for most people to place the mat. The vehicle mat can also be placed from the left side. Both of these methods are alternative implementations designed for convenient mat placement, and the valve system 4 is also oriented differently. To facilitate the easy sliding of the mat from the receiving unit, ball bearings, molded ball bearings, or transfer rollers can be integrally formed on the partition wall of the receiving unit to reduce the friction between the vehicle mat and the partition wall, allowing it to slide smoothly without jamming. For those skilled in the art, it is also possible to insert the vehicle mat from the back of the receiver, depending on the specific circumstances. The mat is not limited to vehicle interior mats, doormats in residential areas, or bathroom door carpets; all can be dispensed and cleaned. This application only describes the dispensing and cleaning of vehicle mats as a preferred embodiment. The nonlinear channel receiving unit 32 with a predetermined curvature refers to a segment, several segments, all, part, or interval of the nonlinear channel 3201 having a certain curvature; any segment with curvature is within the scope of protection of this application. For those skilled in the art, it is also possible to insert the vehicle mat 12 from the back of the receiver, depending on the specific circumstances. The mats are not limited to those inside vehicles, doormats in residential areas, or carpets at bathroom entrances; they can all be distributed and cleaned. This application only describes the distribution and cleaning of vehicle mats as a preferred embodiment.
