[0003] This disclosure relates in its entirety to surface maintenance machines. More specifically, this disclosure relates to surface maintenance machines having visual markings corresponding to maintenance intervals. Background Technology
[0004] Surface maintenance machines can be used to perform one or more surface maintenance tasks, such as brushing, cleaning, polishing, and peeling. To perform these tasks, surface maintenance machines require regular maintenance to ensure proper operation.
[0005] After a machine has been operated, one or more maintenance tasks may need to be performed. Some maintenance tasks may be daily, while others may be weekly or monthly. However, machine operators may not always be aware of what types of maintenance tasks need to be performed or when they need to be performed. Furthermore, several operators may use the same machine for surface maintenance tasks, or there may be high staff turnover, so each operator may not know whether or when a maintenance task has been performed. This can lead to machine damage, resulting in repair needs and / or machine downtime. What is desirable is a maintenance plan that is clearly visible to operators, highlighting necessary maintenance tasks and indicating the frequency at which they should be performed. Summary of the Invention
[0006] Generally, this disclosure relates to surface maintenance machines having visual markings corresponding to maintenance intervals. In one example, a method of maintaining a surface maintenance machine may include: identifying a first mark on the surface maintenance machine bearing a first visual mark, the first mark corresponding to a first service component of the surface maintenance machine, the first visual mark being consistent with a first maintenance frequency; identifying a second mark on the surface maintenance machine bearing a second visual mark, the second visual mark being visually different from the first visual mark, the second mark corresponding to a second service component of the surface maintenance machine, the second visual mark being consistent with a second maintenance frequency different from the first maintenance frequency. The method may further include: determining whether a first time period corresponding to the first maintenance frequency has elapsed since one or more maintenance tasks were recently performed on the first service component, and if so, performing the one or more maintenance tasks on the first service component; and determining whether a second time period corresponding to the second maintenance frequency has elapsed since one or more maintenance tasks were recently performed on the second service component, and if so, performing the one or more maintenance tasks on the second service component.
[0007] In another example, a method for creating a surface maintenance machine with indicators of a maintenance schedule may include: providing the surface maintenance machine. The maintenance machine may include: a mobile body; a solution tank for containing a quantity of cleaning fluid; wheels for supporting and transporting the mobile body; one or more surface maintenance tools supported by the mobile body; a first set of service components; and a second set of service components. The method may further include: installing a first mark on the surface maintenance machine with a first visual identifier corresponding to a first service component of the surface maintenance machine, the first visual identifier being consistent with a first maintenance frequency, and the first mark being set as part of or adjacent to the first service component; and installing a second mark on the surface maintenance machine with a second visual identifier visually different from the first visual identifier, the second mark corresponding to a second service component of the surface maintenance machine, the second visual identifier being consistent with a second maintenance frequency different from the first maintenance frequency, and the second mark being set as part of or adjacent to the second service component.
[0008] In another example, a surface maintenance machine with an indicator of a maintenance schedule may include: a mobile body; a solution tank for containing a certain amount of cleaning fluid; wheels for supporting and transporting the mobile body; one or more surface maintenance tools supported by the mobile body; a first set of service components; and a second set of service components. The surface maintenance machine may also include: a first mark on the surface maintenance machine bearing a first visual sign, the first mark corresponding to a first service component of the surface maintenance machine, the first visual sign being consistent with a first maintenance frequency, and the first mark being set as part of or adjacent to the first service component; and a second mark on the surface maintenance machine bearing a second visual sign, the second visual sign being visually different from the first visual sign, the second mark corresponding to a second service component of the surface maintenance machine, the second visual sign being consistent with a second maintenance frequency different from the first maintenance frequency, and the second mark being set as part of or adjacent to the second service component.

[0020] Exemplary embodiments of this disclosure may be included at and performed at a surface maintenance machine 100. Such a surface maintenance machine 100 requires the performance of one or more maintenance tasks to ensure the proper operation and lifespan of the machine 100. In some cases, one or more maintenance tasks may need to be performed on the machine. Some maintenance tasks may be tasks that need to be performed daily, while others may be tasks that need to be performed weekly or monthly. However, the machine operator may not always know what type of maintenance task needs to be performed or when said task needs to be performed on the machine. Furthermore, several operators may use the same machine to perform surface maintenance tasks, or there may be high staff turnover, so each operator may not know whether or when a maintenance task has been performed on the machine. This can lead to damage to the machine, resulting in repair needs and / or machine downtime. Therefore, it may be advantageous for the machine 100 to provide a first marking on the surface maintenance machine 100 indicating a maintenance schedule and a second marking on the surface maintenance machine.
[0021] Figure 1 This is a perspective view of the front and right side of an exemplary surface maintenance machine 100, and Figure 2This is a perspective view of the rear and right side of a surface maintenance machine 100. In the illustrated embodiment, machine 100 is a push-type surface maintenance machine (e.g., for performing one or more surface maintenance tasks on hard surfaces). In other embodiments, the machine may alternatively be a ride-on machine or a self-propelled machine. Embodiments of machine 100 include one or more surface maintenance tools, a first set of service components, and a second set of service components supported on a mobile body 110. The mobile body 110 includes: a frame supported on wheels 120 for travel on the surface to be treated; and peripheral protection 130. Figure 2 As shown, the mobile body 110 includes a grip handle 128, a lifting ring 129, and operator controls (including a manual / autonomous mode user input mechanism 126). The user input mechanism 126 may include a user interface 127, which may include an interactive touchscreen, allowing the user to interact with the touchscreen to control the machine 100. The machine 100 may be powered by an onboard power source, such as one or more batteries.
[0022] Machine 100 typically includes: a base 102 comprising a frame; and a cover 104 attached to the side of the base 102 by a hinge, such that the cover 104 is pivotable upwards to provide access to the interior of the base 102. The interior of the base 102 may also include a battery power source and other electronic components of the machine 100. The interior of the base may also include a fluid source tank and a fluid recovery tank. The fluid source tank contains fluid sources, such as cleaning agents or disinfectant fluids that can be applied to the ground surface during processing operations. The fluid recovery tank contains recovered fluid sources that have been applied to the ground and become soiled.
[0023] The base 102 also includes a fluid recovery device comprising a first scraper 124A and a second scraper 124B. The first scraper 124A and the second scraper 124B are in vacuum communication with a fluid recovery tank. In operation, the first scraper 124A and the second scraper 124B recover dirty fluid from the floor surface and help transport it to the recovery tank. The base 102 also includes a third scraper 125, which is locating on the underside of the base 102. Although the third scraper 125 is shown positioned on the lower right side of the base 102, it is conceivable that a fourth scraper may also be positioned on the lower left side of the base 102 (although not explicitly shown). The base 102 carries a cleaning head assembly 150. The cleaning head assembly 150 is attachable to the base 102 such that the cleaning head assembly 150 can be lowered to a cleaning position and raised to a traveling position. The cleaning head assembly 150 engages with existing machines using any known mechanisms, such as suspension and lifting mechanisms. The cleaning head assembly 150 may include one or more rotatable brushes, such as disc or cylindrical scrubbing brushes. Alternatively, the cleaning head assembly 150 may include other cleaning tools, such as sweeping brushes or polishing pads, abrasive pads, or buffing pads. The brush or pad is held by a driver (e.g., a brush driver or pad driver, respectively), which is detachable from the hub of the cleaning head assembly 150 along with the brush or pad. In some embodiments, the cleaning head assembly 150 includes a magnetic coupling system that allows non-contact attachment and alignment between the pad driver or brush driver and the hub.
[0024] When machine 100 is operated in manual drive mode, the grip handle 128 and lifting ring 129 can be configured to move machine 100 along a surface where a surface maintenance task is desired. To initiate movement of machine 100, a user can grasp the grip handle 128 and actuate the lifting ring 129 to apply a prime mover to machine 100. For example, the lifting ring 129 can be configured to be actuated by the user applying a pulling force to the lifting ring 129 (e.g., to move the lifting ring 129 toward the grip handle 128). A first actuation of the lifting ring 129 (e.g., the user applying a pulling force to the lifting ring 129) initiates the application of a prime mover to machine 100, and a second actuation of the lifting ring 129 (e.g., the user releasing the lifting ring 129, thus terminating the pulling force at the lifting ring) terminates the application of a prime mover to machine 100. The grip handle 128 provides a surface that the user of machine 100 can grasp during manual operation and apply desired user-originating forces. For example, in manual drive mode, the grip handle 128 can be grasped and used by the user to apply user force to the machine 100 in different directions, so that the machine 100 moves forward, backward and rotates in various directions.
[0025] In some cases, machine 100 may include a controller (not explicitly shown). The controller may be, for example, a programmable processor configured to execute non-transitory computer-readable instructions stored in a non-transitory memory component (e.g., located at the controller). As an example, the controller may include instructions from Roboteq. ™ The controller, serial number SBLM2360T. Execution of non-transitory computer-readable instructions at the controller causes machine 100 to perform one or more of the various features disclosed herein.
[0026] The lifting ring 129 can be coupled to the controller via a wired or wireless protocol. As indicated, the lifting ring 129 is configured to be actuated to move the machine 100 along a surface where a surface maintenance task is desired to be performed. When actuated, the lifting ring 129 can be configured to send a corresponding lifting ring input signal to the controller. The controller can receive the lifting ring 129 input signal and, in response, output control signals to one or more components at the machine 100 (e.g., one or two independently controlled motors) to cause such components to perform corresponding actions.
[0027] The manual / autonomous mode user input mechanism 126 can be coupled to the controller via a wired or wireless protocol. The manual / autonomous mode user input mechanism 126 can receive one or more inputs from a user of machine 100 and thus send one or more corresponding input signals to the controller. For example, the manual / autonomous mode user input mechanism 126 can be configured to send a mode control signal to the controller, corresponding to either a manual mode command or an autonomous mode command, when actuated. For example, a first actuation of the manual / autonomous mode user input mechanism 126 may cause it to send a manual mode control signal to the controller, and a second actuation of the manual / autonomous mode user input mechanism 126 may cause it to send an autonomous mode control signal to the controller. As an illustrative example, a first actuation of the manual / autonomous mode user input mechanism 126 may be a user providing a manual mode selection at the manual / autonomous mode user input mechanism 126 (e.g., via a manual mode button at the manual / autonomous mode user input mechanism 126), and a second actuation of the manual / autonomous mode user input mechanism 126 may be a user providing an autonomous mode selection at the manual / autonomous mode user input mechanism 126 (e.g., via an autonomous mode button at the manual / autonomous mode user input mechanism 126).
[0028] When the controller receives a manual mode command from the manual / autonomous mode user input mechanism 126, in response, the controller may execute non-transitory computer-readable instructions to configure the machine 100 to operate in manual drive mode. Similarly, when the controller receives a manual mode command from the manual / autonomous mode user input mechanism 126, in response, the controller may execute non-transitory computer-readable instructions to configure the machine 100 to operate in autonomous drive mode.
[0029] When the surface maintenance machine 100 is configured to operate in manual drive mode (e.g., in response to the controller receiving a mode control signal corresponding to a manual mode command), the torque assist user mechanism can be activated to send a torque assist control signal to the controller.
[0030] The surface maintenance machine 100 may also include a power source, a first wheel motor, a first driven wheel 220, a second wheel motor, and a second driven wheel. The power source may be, for example, one or more rechargeable batteries. The machine 100 may include a charging cable 145 operatively coupled to the power source (e.g., one or more rechargeable batteries). The charging cable 145 may be stored on the machine 100 using a power cable holder 147. The power source may be configured to provide operating power to various (e.g., all) electrically driven components at the machine 100.
[0031] As noted, machine 100 can switch between a manual drive mode and an autonomous drive mode (e.g., via actuation of the manual / autonomous mode user input mechanism 126). To facilitate operation of machine 100 in autonomous drive mode, machine 100 may include one or more onboard vision sensors 139. Vision sensors 139 may be coupled to a controller via wired or wireless protocols. Vision sensors 139 may be configured to scan and detect features in the environment surrounding machine 100. In some embodiments, vision sensors 139 may include one or more of visible light and / or thermal (infrared) vision cameras, LIDAR sensors, laser beacons, ultrasonic sensors, etc., to detect features of the environment (such as physical boundaries, etc.). In some embodiments, vision sensors 139 may be positioned at various spaced locations on machine 100 (e.g., front, side, rear, etc.) to acquire data corresponding to areas at different locations around machine 100 over a relatively wide field of view. In some specific embodiments, the field of view of the vision sensor 139 may correspond to an angle between approximately 200 degrees and approximately 300 degrees and a radius between approximately 50 feet and 150 feet. In a more specific embodiment, the field of view of the vision sensor 139 may be approximately 240 degrees and a radius of approximately 90 feet.
[0032] In some embodiments, also to facilitate operation of the surface maintenance machine 100 in autonomous driving mode, the machine 100 may include a front camera 140, a front lower sensor 143, a rear lower sensor 141, and a side camera 142. While the machine 100 is shown to include a single front lower sensor 143, a single rear lower sensor 141, and a single side camera 142, it should be understood that the machine 100 may include additional rear lower sensors, front lower sensors, and side cameras. For example, since the front lower sensor 143 is shown located on the front lower right side of the machine 100, it should be understood that an additional front lower sensor is included on the front lower left side. The front lower sensor 143, rear lower sensor 141, and side camera 142 may be coupled to a controller, and each of the front lower sensor 143, rear lower sensor 141, and side camera 142 may each include a wireless transceiver configured to output and receive wireless signals. The front lower sensor 143, rear lower sensor 141, and side-mounted camera 142 allow for the determination of the machine 100's location, such as before, during, or after mapping the location where the machine 100 will operate autonomously. In some embodiments, one or more of the front lower sensor 143, rear lower sensor 141, and front vision sensor 139 may include a Global Positioning System (“GPS”) sensor. Alternatively or additionally, one or more of the front lower sensor 143, rear lower sensor 141, and front vision sensor 139 may include an inertial measurement unit (e.g., a compass, accelerometer, gyroscope, magnetometer, etc.). Furthermore, additional components such as wireless communication beacons (e.g., WiFi or Bluetooth) may be provided at one or more of the front lower sensor 143, rear lower sensor 141, and front vision sensor 139 to improve positioning accuracy.
[0033] To further assist the surface maintenance machine 100 in operating autonomously, the machine 100 may include a mapping system. The mapping system may be executed, for example, at a controller, with executable instructions such as those via a mapping processor and a mapping computer at the controller. The mapping processor may have one or more integrated circuits that can electrically communicate with an onboard or remote non-transitory memory component. The memory component may store mapping instructions in the form of a mapping software program that can be executed by the mapping processor to generate a map used by the machine 100 to navigate positions in autonomously driven mode. The mapping processor may be coupled (e.g., via the controller) to one or more vision sensors 139 and / or a front lower sensor 143, a rear lower sensor 141, and a side camera 142. For example, the graphics processor may (e.g., via circuitry disposed on machine 100) be coupled to vision sensor 139 and / or lower front sensor 143, lower rear sensor 141, and side camera 142, such that data collected by vision sensor 139 and / or lower front sensor 143, lower rear sensor 141, and side camera 142 (e.g., electrical signals representing the data) can be transmitted to the graphics processor via circuitry. The graphics processor may also send control signals to initiate data collection at vision sensor 139 and / or lower front sensor 143, lower rear sensor 141, and side camera 142.
[0034] In some examples, the graphics system may also include a visualization processor. This visualization processor may be configured as part of a controller at the surface maintenance machine 100 (e.g., a GPGPU component at the controller). The visualization processor may have one or more integrated circuits that can electrically communicate with the graphics processor. Additionally, the visualization processor may electrically communicate with onboard and / or remote memory components. The memory may store computer-readable visualization instructions in the form of a visualization software program that can be executed by the visualization processor to generate a map of the locations where the machine 100 will operate autonomously. The controller can then execute the generated map to provide control signals to the motors.
[0035] When in autonomous drive mode, the surface maintenance machine 100 can be configured to operate in rate control mode (sometimes referred to as speed control mode) to apply motive force to driven wheels (e.g., wheel 120) via independently controlled motors. For example, the controller can execute a rate control mode program stored in a non-transitory memory component at the machine 100 in the form of computer-readable instructions executable by the controller, so that the controller controls the movement of the machine 100 via rate control mode.
[0036] After machine 100 has been operated, one or more maintenance tasks may be performed on machine 100 to ensure the proper operation of machine 100 and its lifespan. These one or more maintenance tasks may include one or more maintenance periods corresponding to a first maintenance frequency and / or a second maintenance period corresponding to a second maintenance frequency. In some cases, the first period may correspond to a number of days ranging from about one day to about seven days. For example, the first period may correspond to one day. In some cases, the first period may correspond to the amount of time that surface maintenance machine 100 has been used. For example, the first period may correspond to the amount of time ranging from about 50 hours to about 1,250 hours. In such examples, the first maintenance frequency may be once a day. For example, the first maintenance frequency may be once a day, and the first period may be one day. In other words, the one or more maintenance tasks may be performed once a day. In another example, the first maintenance frequency may be once every 200 hours of machine use, and the first period may be 200 hours of machine 100 use. In other words, the one or more maintenance tasks may be performed once after every 200 hours of machine 100 use.
[0037] In some cases, the second time period may correspond to a number of days ranging from approximately two to approximately seven days. For example, the second time period may correspond to seven days. In such examples, the second maintenance frequency may be once every seven days. For example, the second maintenance frequency may be once, and the second time period may be seven days (e.g., once a week).
[0038] Surface maintenance machine 100 may include a first mark with a first visual identifier and a second mark with a second visual identifier, wherein the second visual identifier is visually different from the first visual identifier. The first visual identifier may correspond to a first service component of machine 100, and the second visual identifier may correspond to a second service component of machine 100. The first and second marks may be placed on machine 100 to highlight a first maintenance frequency and a second maintenance frequency for the one or more maintenance tasks, which helps the operator of machine 100 know which tasks need to be performed. For example, one or more maintenance tasks may need to be performed daily, while another maintenance task among the one or more maintenance tasks may only need to be performed weekly.
[0039] In some cases, a first mark bearing a first visual identifier may be affixed to, positioned adjacent to, or set as part of the first service component. For example, the first mark may be positioned on an actuator used when performing one or more maintenance tasks on the first service component. In another example, the first mark may include a portion of the first service component bearing the first visual identifier. In some cases, the first visual identifier may include a first color. In some cases, the first color is yellow. In other cases, the first color may be turquoise, purple, blue, or any other suitable color. In some cases, the first visual identifier may include a decal containing the first color, which may be positioned adjacent to the first service component on machine 100.
[0040] In some cases, the first visual sign may include a first color and / or a decal including Braille instructions. These are merely examples. In some examples, the first and second visual signs may include patterns, color combinations, images, symbols (e.g., letters, words, characters, graphics), etc. In one aspect, the first or second visual sign may be a calendar to indicate that the first or second frequency corresponds to once a month. The difference between the first and second visual signs may be obvious to the user in order to distinguish service parts that are maintained at the first frequency from those that are maintained at the second frequency. The use of first and second visual signs is only one example and can be extended to additional visual signs. In some examples, there are third, fourth, fifth, and possibly more different visual signs, each with a distinct difference, each corresponding to a specific maintenance frequency, and each visual sign is marked on, adjacent to, or as part of a specific service part.
[0041] As described above, the first visual marker may correspond to the first service component of machine 100. In some cases, the first service component may include a cleaning head assembly 150 (e.g., one or more rotating brushes, cleaning brushes, or polishing pads, abrasive pads, or buffing pads), a first scraper 124A, a second scraper 124B, and a third scraper 125, a filter basket, the power cable / power supply of machine 100, a recycling bin, a solution tank, one or more visual sensors 139 and / or a front lower sensor 143, a rear lower sensor 141, and a side-mounted camera 142. These are merely examples.
[0042] In some cases, a second mark with a second visual identifier may be affixed to, positioned adjacent to, and / or part of the second service component. For example, the second mark may be positioned on an actuator used when performing one or more maintenance tasks on the second service component. In another example, the second mark may include a portion of the second service component with the second visual identifier. In some cases, the second visual identifier may include a second color. In some cases, the second color is blue. In other cases, the second color may be turquoise, purple, yellow, or any other suitable color. In some cases, the second visual identifier may include a decal containing the second color, which may be positioned adjacent to the second service component on machine 100. In some cases, the second visual identifier may include a decal with the second color and / or Braille instructions. These are merely examples.
[0043] As described above, the second visual sign may correspond to a second service component of machine 100. In some cases, the second service component may include a battery or other power source (such as charging cable 145) and a peripheral protective element 130. These are merely examples.
[0044] Figure 3 This is a lower right side view of a surface maintenance machine 100, showing an enlarged view of the cleaning head assembly 150, the first scraper 124A, the second scraper 124B, and the third scraper 125. Figure 3 In the diagram, a first scraper 124A and a second scraper 124B are shown attached to a scraper frame 162. The scraper frame 162 may be attached directly or indirectly to the underside of the base 102 of the machine 100. In some cases, the first scraper 124A and the second scraper 124B may be releasably connected to the scraper frame 162. For example, as... Figure 3 As shown, the scraper frame 162 may include a release actuator, such as a release lever 160. The release lever 160 can be used to assist in separating or disconnecting the first scraper 124A and the second scraper 124B from the scraper frame 162. Although the release actuator shown is the release lever 160, it is conceivable that other release actuators, such as release buttons or screw handles connected to threaded bolts or threaded nuts that can form a connector, may be used in addition to or alternatively.
[0045] The cleaning head assembly 150 may include one or more rotatable brushes, such as disc or cylindrical scrubbing brushes. Alternatively, the cleaning head assembly 150 may include other cleaning tools, such as sweeping brushes or polishing pads, abrasive pads, or buffing pads. The brush or pad is held by a driver (e.g., a brush driver or pad driver, respectively), which is detachable from the hub of the cleaning head assembly 150 along with the brush or pad. In some embodiments, the cleaning head assembly 150 includes a magnetic coupling system that allows non-contact attachment and alignment between the pad driver or brush driver and the hub.
[0046] As previously discussed, the cleaning head assembly 150, the first scraper 124A, the second scraper 124B, and the third scraper 125 can be considered as part of the first service component of the machine 100. Figure 3 As shown, a first mark may be positioned on a release lever 160 (e.g., an actuator) used when performing one or more maintenance tasks on the first scraper 124A and the second scraper 124B. In such an example, the release lever 160 has a first visual mark corresponding to the first scraper 124A and the second scraper 124B. In this case, the first visual mark is a first color (e.g., yellow). Additionally, a decal 166 is positioned adjacent to the release lever 160 on the machine 100, which also has the first visual mark, and the scraper frame 162 also has the first visual mark, such as the first color. In another example, the first mark may include the first scraper 124A and the second scraper 124B with the first visual mark, such as the first scraper 124A and / or the second scraper 124B having a first color. The first visual sign reminds the operator of machine 100 to check the first scraper 124A and the second scraper 124B to determine whether the first scraper 124A and the second scraper 124B need to be cleaned, flipped and / or replaced, and if so, to clean, flip and / or replace the first scraper 124A and / or the second scraper 124B respectively.
[0047] like Figure 3 As shown, the cleaning head assembly 150 includes a first marking corresponding to the cleaning head assembly 150 (e.g., a scrubbing brush). In this case, the cleaning head assembly 150 has a first visual marking including a first color. The first marking on the cleaning head assembly 150 corresponds to one or more maintenance tasks to be performed on the cleaning head assembly 150 and alerts the operator of the machine 100 to check whether the cleaning head assembly 150 is damaged, needs cleaning, flipping, or replacement, and if so, to clean, flip, and / or replace the cleaning head assembly 150. In other examples, a portion of the cleaning head assembly 150 (such as some or all of the bristles on the scrubbing brush of the cleaning head assembly 150) may have a first visual marking, such as having a first color.
[0048] Figure 4 This is a rear view of the surface maintenance machine 100, showing an enlarged view of a charging cable 145 wound on a cable tray 147.
