[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily implement the invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0033] Figure 1 is a perspective view of the packaging box cleaning machine 1 of the present invention.

[0034] Referring to Figure 1, the alarm system for the packaging box cleaning machine may include the packaging box cleaning machine 1. The packaging box cleaning machine 1 may include an input unit 10, a cleaning unit 20, and a discharge unit 30.

[0035] The feeding unit 10 can be configured to feed the cold-insulating packaging box P in a flattened state. The cold-insulating packaging box P is a recyclable box and can be repeatedly converted into an unfolded flattened state or an assembled box state. The cold-insulating packaging box P can be fed in an unfolded flattened state and cleaned while moving along the moving path A guided by the packaging box washing machine 1.

[0036] The cleaning unit 20 can be configured to clean the inserted cold packaging box P while it moves along a first direction (e.g., the X-axis direction). Here, the first direction (X-axis direction) can refer to the direction in which the inserted cold packaging box P moves. Therefore, the aforementioned movement path A can refer to the movement path A of the cold packaging box P moving along the first direction (X-axis direction).

[0037] The cleaning unit 20 can be roughly divided into a cleaning area 20a and a driving area 20b. The cleaning area 20a may be located at the top, and the driving area 20b may be located at the bottom. The cleaning area 20a refers to the area where the cold storage box P is cleaned, and the driving area 20b refers to the area where the equipment used to drive the cleaning area 20a is located.

[0038] The cleaning area 20a may be equipped with a cleaning device 100 configured to clean the cold packaging box P, and a transport unit 200 configured to move the cold packaging box P. The drive area 20b may be equipped with a plurality of motors for driving the cleaning device 100 and the transport unit 200.

[0039] The packaging box cleaning machine 1 may further include a cover 24 that covers the cleaning section 20. For example, the cover 24 may cover the cleaning area 20a located at the top of the packaging box cleaning machine 1 and the drive area 20b located at the bottom. The cover 24 is configured to prevent the various components of the packaging box cleaning machine 1 from being exposed to external foreign objects, cold air, etc. The cover 24 is made of a transparent material so that operators can visually inspect the interior of the cleaning section 20 from the outside. Furthermore, at least one side of the cover 24 may have at least one door 25, 26 that can be opened and closed. Operators can open the doors 25, 26 to address or maintain the various components of the cleaning section 20.

[0040] The discharge section 30 is configured to discharge the cleaned insulated packaging box P. The discharge section 30 can be located at the end of the movement path A, and the insulated packaging box P, after being cleaned by the cleaning section 20, is discharged to an external area. Operators can retrieve the insulated packaging box P discharged by the discharge section 30.

[0041] Figure 2 is a top view of the cleaning area 20a of the packaging box cleaning machine 1 of the present invention, and Figure 3 is a side view of the packaging box cleaning machine 1 of the present invention.

[0042] Referring to Figures 2 and 3, the cleaning unit 20 may include at least one cleaning towel 130. The cleaning towel 130 is configured to wipe the surface of the cooler box P. The cleaning towel 130 may be located on the movement path A of the cooler box P and rotate during the movement of the cooler box P along a first direction (X-axis direction). The cleaning towel 130 may be configured to rotate around an axis parallel to a second direction (e.g., Z-axis direction) perpendicular to the first direction (X-axis direction). For example, the second direction may be the height direction of the cleaning unit 20. However, the second direction is not necessarily limited to a direction perpendicular to the first direction, but may be a direction tilted at a specific angle from the direction perpendicular to the first direction. As the cooler box P moves and passes the cleaning towel 130, the cleaning towel 130 may rotate and wipe the surface of the cooler box P.

[0043] The cleaning towel 130 has a disc-shaped structure centered on a rotation axis R, and a cleaning surface 1301 can be formed on one or the other side of the disc. That is, the cleaning towel 130 can be driven to rotate around a rotation axis R perpendicular to the cleaning surface 1301 while cleaning the cold storage box P.

[0044] The cleaning towel 130 rotates around a rotation axis parallel to the second direction (Z-axis direction). During this time, the cooler box P moves and passes over the cleaning towel 130, which can rotate and wipe the surface of the cooler box P using its cleaning surface 1301. Therefore, since the cleaning towel 130 of this invention rotates with its axis perpendicular to the movement path A, it occupies less space and is more efficient compared to the case where the cleaning towel 130 rotates with its axis parallel to the movement path A. Furthermore, there is less slippage between the moving cooler box P and the cleaning towel 130, ensuring sufficient friction and cleaning time, thereby ensuring better cleaning power.

[0045] The washing unit 20 may include at least one washing device 100. The washing device 100 may be a device for washing towels 130. The washing device 100 may include a top washing device 110 and a bottom washing device 120. The top washing device 110 may be located above the movement path A, and the bottom washing device 120 may be located below the movement path A.

[0046] Multiple top cleaning devices 110 and bottom cleaning devices 120 may be configured. For example, top cleaning device 110 may include a first top cleaning device 110a and a second top cleaning device 110b, and bottom cleaning device 120 may include a first bottom cleaning device 120a and a second bottom cleaning device 120b. The first top cleaning device 110a and the second top cleaning device 110b are used to distinguish positions, and their structures may be identical or similar. Similarly, the structures of the first bottom cleaning device 120a and the second bottom cleaning device 120b may also be identical or similar. However, the first top cleaning device 110a and the second top cleaning device 110b, or the first bottom cleaning device 120a and the second bottom cleaning device 120b, may be arranged symmetrically according to their positions. For example, the first bottom cleaning device 120a and the second bottom cleaning device 120b may be symmetrical about their midpoints.

[0047] In one embodiment, the first top cleaning device 110a, the first bottom cleaning device 120a, the second bottom cleaning device 120b, and the second top cleaning device 110b of the packaging box cleaning machine 1 can be sequentially arranged along the moving path A of the cold packaging box P. In this case, the cold packaging box P can be cleaned in the order of top, bottom, bottom, top. However, this arrangement order can be appropriately changed and is not necessarily limited to this; it can also be arranged in the order of top, top, bottom, bottom.

[0048] The cleaning unit 20 may include a transport unit 200. The transport unit 200 may be configured to move the insulated packaging box P along a movement path A. For example, the transport unit 200 may include a conveyor belt for transporting the insulated packaging box P. The conveyor belt rotates, and the insulated packaging box P in contact with the conveyor belt can move along the first direction (X-axis direction) with the conveyor belt while in contact with the conveyor belt.

[0049] The transport unit 200 may include a top transport unit 210 and a bottom transport unit 220. The top transport unit 210 may be located above the travel path A, and the bottom transport unit 220 may be located below the travel path A. Multiple top transport units 210 and bottom transport units 220 may be configured. For example, the top transport unit 210 may include a first top transport unit 210a and a second top transport unit 210b. The bottom transport unit 220 may include a first bottom transport unit 220a and a second bottom transport unit 220b.

[0050] In one embodiment, the top transport section 210 may be arranged opposite to the bottom cleaning device 120, and the bottom transport section 220 may be arranged opposite to the top cleaning device 110. For example, when the cleaning device 100 is arranged in the order of the first top cleaning device 110a, the first bottom cleaning device 120a, the second bottom cleaning device 120b, and the second top cleaning device 110b, the transport section 200 may be arranged in the order of the first bottom transport section 220a, the first top transport section 210a, the second top transport section 210b, and the second bottom transport section 220b. Therefore, while the cold pack box P moves along the moving path A with one side in contact with the transport section 200, the other side of the cold pack box P may come into contact with the cleaning device 100 and be cleaned.

[0051] The cleaning unit 20 may include a drain section 80. The drain section 80 may be configured to discharge water or cleaning water used for cleaning the cold storage box P. For example, the drain section 80 may be located below the cleaning device 100 and the transport unit 200, and may include a surface that slopes to one side. A drain pipe 81 may be provided at the end of the sloped surface to discharge the used water or cleaning water to the outside.

[0052] The packaging box washing machine 1 may further include a wastewater tank 90. ​​Wastewater may refer to the aforementioned used water or washing water. The wastewater tank 90 may be configured to hold wastewater. The wastewater tank 90 may be configured in a movable manner and to hold wastewater discharged from the drain pipe 81.

[0053] The packaging box cleaning machine 1 may further include a heater section 28. The heater section 28 may be configured to adjust the temperature inside the cover section 24. For example, the heater section 28 may be a hot air blower. One heater section 28 may be provided in the cleaning area 20a and the drive area 20b respectively. The heater section 28 can dissipate hot air to prevent the structure of the cleaning section 20 from freezing and cracking.

[0054] The input unit 10 may include an input transport unit 11 and an input transport motor 12. The input transport unit 11 may be configured to transport the insulated packaging box P in the direction toward the cleaning unit 20. For example, the input transport unit 11 may be a conveyor belt. The input transport motor 12 may be configured to drive the input transport unit 11.

[0055] Figure 4 is a side view showing the repair mode of the packaging box cleaning machine 1 of the present invention.

[0056] Referring to Figures 4 and 3, the packaging box cleaning machine 1 can be configured to switch between cleaning mode and repair mode.

[0057] The cleaning mode is used to clean the cold storage box P. In this mode, the cleaning towel 130 can be adjacent to the movement path A.

[0058] The repair mode is used for maintaining the packaging box washing machine 1. In this mode, the washing towel 130 can be moved relatively away from the movement path A. Since the washing towel 130 is moved away from the movement path A in repair mode, sufficient working space is ensured for the operator to inspect the washing device 100.

[0059] Figure 3 shows the cleaning mode status, and Figure 4 shows the repair mode status.

[0060] Specifically, the top cleaning device 110 can be configured to switch between cleaning mode and repair mode. One side of the top cleaning device 110 is connected to the buffer device 21 (shock absorber), and the other end of the buffer device 21 can be connected to the frame 23 of the packaging box cleaning machine 1. The buffer device 21 is adjustable in length and allows the cleaning device 100 to rotate.

[0061] At this time, the top cleaning device 110 can be connected to the frame 23 of the packaging box cleaning machine 1 via the bearing part 22, and the top cleaning device 110 can rotate with the bearing part 22 as a reference. For example, referring to Figures 3 and 4 together, the top cleaning device 110 can rotate upward with the bearing part 22 as the center to switch to repair mode, and conversely, it can rotate downward with the bearing part 22 as the center to switch to cleaning mode.

[0062] The top transport section 210 can also be configured to switch between a cleaning mode and a repair mode. In the cleaning mode, one side of the top transport section 210 can be adjacent to the movement path A; in the repair mode, one side of the top transport section 210 can be relatively away from the movement path A. In the cleaning mode, the top transport section 210 can move the cold packaging box P along the first direction (X-axis direction) while in contact with one side of the cold packaging box P.

[0063] One side of the top transport section 210 can be connected to the buffer device 21, and the other end of the buffer device 21 can be connected to the frame 23 of the packaging box washing machine 1. The other end of the transport section 200 can be connected to the frame 23 of the packaging box washing machine 1 via the bearing section 22. As the length of the buffer device 21 changes, the top transport section 210 can rotate with the bearing section 22 as a reference. The top transport section 210 can enter the repair mode when rotating upward and the cleaning mode when rotating downward.

[0064] Figure 5 is a top view of the drive area 20b of the packaging box cleaning machine 1 of the present invention.

[0065] Referring together with Figures 5 and 2 to 4, the cleaning unit 20 may include at least one motor. The motor can provide driving force to the transport unit 200 and the cleaning device 100.

[0066] For example, the motor may include at least one of the following: a first bottom transport motor 310a configured to drive the first bottom transport section 220a; a second bottom transport motor 310b configured to drive the second bottom transport section 220b; a top transport motor 320 configured to drive the top transport section 210; a first bottom cleaning motor 330a and a second bottom cleaning motor 330b configured to drive the first bottom cleaning device 120a and the second bottom cleaning device 120b; a first top cleaning motor 340a configured to drive the first top cleaning device 110a; and a second top cleaning motor 340b configured to drive the second top cleaning device 110b.

[0067] In one embodiment, the first bottom transport motor 310a can be connected to the first bottom transport section 220a via the first drive transmission member 360. The first drive transmission member 360 can transmit the driving force of the first bottom transport motor 310a to the first bottom transport section 220a. For example, the first drive transmission member 360 can be configured as a V-shaped rubber belt. By using a V-shaped rubber belt, the noise generated by driving the first bottom transport section 220a can be reduced, and the driving force can be stably transmitted to the first bottom transport section 220a. However, in addition to the above-mentioned V-shaped rubber belt, the first drive transmission member 360 can also be configured in various shapes and types.

[0068] In one embodiment, the second bottom transport motor 310b can be connected to the second bottom transport section 220b via the first drive transmission member 360, thereby transmitting driving force to the second bottom transport section 220b. The first drive transmission member 360 connected to the second bottom transport motor 310b can be configured, for example, as a V-belt.

[0069] In one embodiment, the top transport motor 320 can be connected to the top transport section 210 via a first drive transmission member 360, thereby transmitting driving force to the top transport section 210. The first drive transmission member 360 connected to the top transport motor 320 can be configured, for example, as a V-belt. The top transport section 210 includes a first top transport section 210a and a second top transport section 210b, and the top transport motor 320 can be connected to both the first top transport section 210a and the second top transport section 210b via a first drive transmission member 360. By driving both transport sections 200 with a single motor and the first drive transmission member 360, space efficiency can be provided.

[0070] The first bottom cleaning motor 330a and the second bottom cleaning motor 330b can be connected to the first bottom cleaning device 120a and the second bottom cleaning device 120b via the second drive transmission member 370. For example, the second drive transmission member 370 can be configured as a chain belt. Since the second drive transmission member 370 connected to the cleaning motor is composed of a chain belt, which has superior mechanical rigidity, fastness, and drive transmission force compared to a rubber belt, the cleaning towel 130 can be rotated stably at a faster speed. However, in addition to the aforementioned chain belt, the second drive transmission member 370 can also be configured in various shapes and types.

[0071] The second drive transmission member 370 can be connected to the washing shaft 140 of each washing towel 130. The first bottom washing device 120a and the second bottom washing device 120b can each have a plurality of washing towels 130. For example, the first bottom washing device 120a and the second bottom washing device 120b can each have four washing towels 130. The plurality of washing towels 130 can be arranged in a direction perpendicular to the first direction (X-axis direction) and perpendicular to the second direction (Z-axis direction). Therefore, two washing towels 130 can be arranged on each side with the center of the moving path A as a reference. The bottom washing device 120 can include a washing shaft 140. One end of the washing shaft 140 can be configured with a sprocket structure that can be connected to the second drive transmission member 370. The bottom washing motors 330a and 330b and the washing shaft 140 can be connected to the second drive transmission member 370.

[0072] The second drive transmission member 370 of the first bottom cleaning motor 330a can be connected to a portion of the cleaning shaft 140a of the first bottom cleaning device 120a and a portion of the cleaning shaft 140b of the second bottom cleaning device 120b. Similarly, the second drive transmission member 370 of the second bottom cleaning motor 330b can be connected to a portion of the cleaning shaft 140a of the first bottom cleaning device 120a and a portion of the cleaning shaft 140b of the second bottom cleaning device 120b. Specifically, each of the bottom cleaning motors 330a and 330b can be connected along the direction of movement to the two cleaning shafts 140a of the first bottom cleaning device 120a and the two cleaning shafts 140b of the second bottom cleaning device 120b. The motor shafts 350a and 350b of the bottom cleaning motors 330a and 330b can be connected to the second drive transmission member 370 from between the two cleaning shafts 140a of the first bottom cleaning device 120a or between the two cleaning shafts 140b of the second bottom cleaning device 120b. This arrangement maintains appropriate tension on the second drive transmission member 370 and reduces the risk of separation of the second drive transmission member 370.

[0073] However, the connection relationships described above are merely examples and do not exclude other connection relationships.

[0074] Figure 6 is a front view of the cleaning water tank 400 of the packaging box cleaning machine 1 of the present invention.

[0075] Referring to Figures 6 and 2 to 5, the cleaning unit 20 may further include a cleaning water tank 400.

[0076] The cleaning water tank 400 can be configured to store water or cleaning water. The cleaning water tank 400 may include a first cleaning water tank 400a and a second cleaning water tank 400b. The first cleaning water tank 400a and the second cleaning water tank 400b can store water or cleaning water, respectively. For example, the first cleaning water tank 400a can store water, and the second cleaning water tank 400b can store cleaning water. Here, cleaning water can refer to a liquid obtained by mixing water and a cleaning agent.

[0077] The cleaning water tank 400 may include a transparent window 410 located at the top. Operators can visually monitor the volume of water or cleaning water stored in the cleaning water tank 400 through the transparent window 410.

[0078] The cleaning water tank 400 may include a water level sensor 420. The water level sensor 420 may be configured to measure the height of the water or cleaning water stored in the cleaning water tank 400.

[0079] The cleaning water tank 400 may include an inlet 430 for injecting water or cleaning water. The inlet 430 may include a mesh 440 configured to filter foreign matter from the injected water or cleaning water.

[0080] The cleaning unit 20 may further include a booster pump 500. The booster pump 500 can be connected to the cleaning water pipes 450a and 450b of the cleaning water tank 400, and the booster pump 500 is configured to move the water stored in the cleaning water tank 400 or the cleaning water to the nozzle 600. The booster pump 500 can move the stored water or the cleaning water by means of pressure.

[0081] The booster pump 500 may include a first booster pump 500a and a second booster pump 500b. The first booster pump 500a may be connected to a first cleaning water tank 400a, and the second booster pump 500b may be connected to a second cleaning water tank 400b.

[0082] The first booster pump 500a can be connected to the first nozzle section 600a, and the second booster pump 500b can be connected to the second nozzle section 600b. When water is stored in the first cleaning water tank 400a and cleaning water is stored in the second cleaning water tank 400b, the first nozzle section 600a can spray water, and the second nozzle section 600b can spray cleaning water. Since the order of storing or spraying water and cleaning water can be appropriately adjusted, it is not necessarily limited to the above example.

[0083] The nozzle portion 600 can be disposed between the cleaning device 100 and the transport portion 200. That is, the nozzle portion 600 can be disposed in the gap between the cleaning device 100 and the transport portion 200. Therefore, even if the nozzle portion 600 sprays water or cleaning water, the transport portion 200 or the cleaning device 100 will not be obstructed.

[0084] The booster pump 500 can be connected to the pressure gauge 27. Referring to Figure 1, the pressure gauge 27 can be installed on one side of the cover portion 24. The pressure gauge 27 can be configured to display the pressure of the booster pump 500. The operator can visually confirm the pressure of the pressure gauge 27 and adjust the pressure of the booster pump 500. The operator can adjust the pressure of the booster pump 500, thereby adjusting the hourly volume or spray force of the water or cleaning water sprayed through the nozzle portion 600.

[0085] Figure 7 is a schematic diagram showing the connection relationship of the operation unit 60 of the packaging box cleaning machine 1 of the present invention.

[0086] Referring together with Figures 7 and 1 to 6, the alarm system of the packaging box cleaning machine 1 may include an operation unit 60.

[0087] The operation unit 60 can be configured to determine whether a preset alarm condition has occurred in the packaging box washing machine 1. The preset alarm condition referred to here may refer to a problem or cessation of operation of the packaging box washing machine 1. The operation unit 60 can be programmed to connect to multiple components of the packaging box washing machine 1 and determine the alarm condition based on signals transmitted from each component. The alarm condition may include various situations, which will be described below.

[0088] The alarm system of the packaging box washing machine 1 may include an alarm device 61. The alarm device 61 can be connected to the operation unit 60. The connection between the alarm device 61 and the operation unit 60 can refer to a connection through the exchange of electrical signals or communication. The position and shape of the alarm device 61 are not limited; the forms shown in Figures 1 and 3 are merely examples. Therefore, the alarm device 61 can be installed on the cover 24 of the packaging box washing machine 1 or on the operation unit 60.

[0089] The alarm device 61 can be configured to issue an alarm when an alarm condition is detected. For example, when the operation unit 60 determines that an alarm condition is detected, the operation unit 60 can send an electrical signal to the alarm device 61 to issue an alarm. Upon receiving the electrical signal, the alarm device 61 can issue an alarm. At this time, the alarm can be issued in at least one of sound or light. For example, the alarm device 61 can be configured to issue both light and sound simultaneously.

[0090] In case of an alarm, operators can see or hear the alarm from alarm device 61 and promptly detect any problems with the packaging box washing machine 1. Therefore, the alarm system of the packaging box washing machine 1 of the present invention facilitates the maintenance of the packaging box washing machine 1 and reduces the discharge of cold-insulated packaging boxes P that are not in good cleaning condition.

[0091] The operation unit 60 can be configured to stop the operation of the packaging box washing machine 1 in the event of an alarm. The operation unit 60 can be configured to interrupt the drive zone 20b of the packaging box washing machine 1 in the event of an alarm. Therefore, the various motors included in the drive zone 20b can stop operating, thereby stopping the transport section 200 or the washing device 100. Furthermore, the operation unit 60 can be configured to switch the top transport section 210 or the top washing device 110 to a repair mode in the event of an alarm. Therefore, operators can immediately perform repairs in the event of an alarm without having to separately switch the top transport section 210 or the top washing device 110 to a repair mode. However, the above example is only one example; the operation unit 60 can be configured to continue operating the packaging box washing machine 1 even in the event of an alarm, and can be configured such that even if the packaging box washing machine 1 is stopped, the top transport section 210 or the top washing device 110 still maintains the washing mode. The above matters can be changed by appropriately programming the operation unit 60.

[0092] The packaging box washing machine 1 may include at least one emergency stop button 70. The emergency stop button 70 may be a button configured to stop the operation of the packaging box washing machine 1. The emergency stop button 70 may be located on the exterior of the packaging box washing machine 1. The location of the emergency stop button 70 is not limited and may be located in a position that is easily and promptly pressed by the operator.

[0093] Alarm situations may include a first alarm situation. The first alarm situation may be when an operator presses the emergency stop button 70. The operator referred to here does not necessarily refer to the person operating the packaging box washing machine 1, but may also include personnel who, although not operating the packaging box washing machine 1, determine it is necessary to stop its operation. When an operator presses the emergency stop button 70, the operation unit 60 may determine that an alarm situation is in effect and send a signal to the alarm device 61 to cause the alarm device 61 to sound an alarm. Simultaneously, the packaging box washing machine 1 may stop operating. The packaging box washing machine 1 may be configured to stop operating directly via the emergency stop button 70, or it may be configured to stop operating via the operation unit 60.

[0094] In the event of alarm 1, the operator can initialize emergency stop button 70 to restart the packaging box washing machine 1. The operator can release emergency stop button 70 to clear alarm 1. For example, the operator can turn emergency stop button 70 to the right and then release it to clear emergency stop button 70.

[0095] The packaging box washing machine 1 includes at least one motor, and each motor may have an inverter. The inverter is configured to control the motor and transmit motor information to the operation unit 60. The operation unit 60 can be connected to each inverter for mutual communication.

[0096] The motor may include at least one of the following: a first bottom transport motor 310a, which is configured to drive the first bottom transport section 220a; a second bottom transport motor 310b, which is configured to drive the second bottom transport section 220b; a top transport motor 320, which is configured to drive the top transport section 210; a first bottom cleaning motor 330a and a second bottom cleaning motor 330b, which are configured to drive the first bottom cleaning device 120a and the second bottom cleaning device 120b; a first top cleaning motor 340a, which is configured to drive the first top cleaning device 110a; and a second top cleaning motor 340b, which is configured to drive the second top cleaning device 110b.

[0097] Each motor may include a separate inverter. For example, the first bottom transport motor 310a may include a first inverter 381, the second bottom transport motor 310b may include a second inverter 382, ​​the top transport motor 320 may include a third inverter 383, the first bottom cleaning motor 330a may include a fourth inverter 384, the second bottom cleaning motor 330b may include a fifth inverter 385, the first top cleaning motor 340a may include a sixth inverter 386, and the second top cleaning motor 340b may include a seventh inverter 387.

[0098] Alarm conditions may include a second alarm condition. The second alarm condition may be a situation where the communication connection between the inverter and the operation unit 60 is poor. For example, the operation unit 60 and the inverter can be connected to each other via a communication cable to communicate with each other. The second alarm condition may include a situation where communication cannot be transmitted smoothly due to physical damage to the communication cable or damage to the inverter.

[0099] In the event of alarm 2, the operator can check the communication cable connecting the inverter and the control unit 60 to ensure there is no poor contact or connection. Once the inspection is complete, the operator can deactivate alarm 2.

[0100] Alarm conditions may include a third alarm condition. The operation unit 60 can be configured to receive information from each motor from the inverter to determine if any motor is malfunctioning. The third alarm condition may be a situation where a motor malfunction has occurred. An error may refer to at least one of the motor's speed, capacitance, or temperature deviating from a preset speed range, capacitance range, or temperature range. In other words, an error may indicate a risk of motor damage. For example, this could be due to: the motor speed being too high, the capacitance being too high and potentially causing motor damage, or the temperature being too high and predicting motor overheating.

[0101] Each of the aforementioned error types has a corresponding designated error code, which can be displayed on the display 62 of the operation unit 60 described below. In the case of the third alarm, the operator can resolve the error in each motor after confirming the error code. Furthermore, the operator can resolve the error in each motor by disconnecting and connecting the power supply to each motor.

[0102] The motor may further include an input transport motor 12. The input transport motor 12 can be configured to drive the input transport section 11. The input transport section 11 can be formed in the input section 10 and configured to transport the insulated packaging box P. The input transport section 11 can be in the form of a conveyor belt. The operator can place the insulated packaging box P in an unfolded state on the conveyor belt, and the insulated packaging box P can move with the conveyor belt.

[0103] The input of the transport motor 12 may include an eighth inverter 388, which can be connected to the operation unit 60 for mutual communication. A poor communication status between the input of the transport motor 12 and the operation unit 60 is equivalent to a second alarm condition, and an error in the input of the transport motor 12 is equivalent to a third alarm condition.

[0104] The packaging box cleaning machine 1 may include doors 25 and 26. Doors 25 and 26 allow operators to enter the interior of the packaging box cleaning machine 1 and are configured to be openable and closable. Operators can open doors 25 and 26 to enter the interior of the packaging box cleaning machine 1 and inspect it.

[0105] The alarm situation may include a fourth alarm situation. The fourth alarm situation may be when doors 25 and 26 are open. When doors 25 and 26 are open, workers may be exposed to the drive mechanism of the cleaning device 100 or transport unit 200, which consists of rotating parts, and may face the risk of being trapped by the rotating parts. Therefore, an alarm is triggered when doors 25 and 26 are open so that workers can be aware of the alarm situation in a timely manner.

[0106] Doors 25 and 26 may include a door sensor 29. The door sensor 29 may be configured to detect whether doors 25 and 26 are open. The operation unit 60 may be connected to the door sensor 29 for mutual communication. The operation unit 60 may determine whether doors 25 and 26 are open based on the signal from the door sensor 29. When doors 25 and 26 are open, the door sensor 29 may transmit an electrical signal indicating that doors 25 and 26 are open to the operation unit 60.

[0107] In the event of alarm number 4, the operator can close doors 25 and 26 to deactivate alarm number 4.

[0108] The cleaning water tank 400 may include a water level sensor 420 configured to measure the height of the stored water or cleaning water, and the water level sensor 420 may be connected to the operation unit 60 for mutual communication.

[0109] Alarm conditions may include a fifth alarm condition. The fifth alarm condition is when the level of stored water or cleaning water, as measured by the water level sensor 420, is below a preset level. When the level of stored water or cleaning water in the cleaning tank 400 is below the preset level, the stored water or cleaning water may be insufficient, and the nozzle 600 may not be able to spray water or cleaning water properly, thus potentially preventing the successful cleaning of the cold-insulated packaging box P. Therefore, the operation unit 60 may be configured to issue an alarm to notify the operator that water or cleaning water needs to be replenished when the stored water or cleaning water is insufficient.

[0110] In the event of alarm number 5, the operator can add water or cleaning water to the cleaning water tank 400 to deactivate alarm number 5.

[0111] The motor speed, capacitance, temperature, and the level of stored water or cleaning water mentioned above can be adjusted by appropriate programming.

[0112] The operation unit 60 can be configured to restart the packaging box washing machine 1 when the alarm has been cleared. Operators can take appropriate measures to clear the alarm in cases 1 through 5, and the operation unit 60 can recognize these measures. Alternatively, operators can directly operate the operation unit 60 to clear the alarm.

[0113] The operator can operate the control unit 60 to restart the packaging box washing machine 1, which has been stopped. Alternatively, the operator can operate the control unit 60 to restart the packaging box washing machine 1.

[0114] Figure 8 is an illustrative representation of the display 62 included in the packaging box cleaning machine 1 of the present invention.

[0115] Referring to Figure 8, the display 62 can be configured to show the history of each alarm status.

[0116] The operation unit 60 may include a display 62. The display 62 may display details of alarm conditions, i.e., the alarm history, in a configuration manner. For example, the display 62 may display alarm conditions 1 to 5, along with the aforementioned error codes. The alarm history may display the occurrence time and content of each alarm condition, along with whether the alarm condition has been cleared.

[0117] Furthermore, operators can configure themselves to select alarm history displayed on monitor 62 for deletion. For example, operators can delete any one alarm history record, or they can delete all alarm history records.

[0118] Referring again to Figure 1, the packaging box cleaning device 100 may further include a barcode reader 40. The barcode reader 40 is configured to sense the barcode recorded on the insulated packaging box P. The barcode reader 40 may be installed in the input section 10. The insulated packaging box P may have a barcode recorded on it for tracking and observation. The barcode reader 40 can identify the barcode and count the number of times the insulated packaging box P has been used.

[0119] The barcode reader 40 can be configured to communicate with the operation unit 60. The display 62 of the operation unit 60 can be configured to display the number of times the insulated packaging box P has been used or cleaned, as identified by the barcode reader 40. The operation unit 60 can be configured to issue an alarm when the number of times the insulated packaging box P has been used or cleaned exceeds a preset number. For example, the operation unit 60 can identify the inherent information of the insulated packaging box P through the barcode reader 40 and transmit it to the storage device inside the packaging box cleaning machine 1 or an external server, thereby recording the number of times the insulated packaging box P has been repeatedly used and cleaned. In this way, management can be carried out in such a way that the number of times the insulated packaging box P has been used and cleaned can be monitored in real time, and the insulated packaging box P can only be reused within the preset number of times it has been used.

[0120] The packaging box cleaning apparatus 100 may further include a sensing unit 50. The sensing unit 50 may be provided in at least one of the input section 10 or the discharge section 30. The sensing unit 50 is configured to sense whether a chilled packaging box P is present in the input section 10 or the discharge section 30. The sensing unit 50 can detect whether the chilled packaging box P is being input or discharged. If the sensing unit 50 does not detect a chilled packaging box P, it can be considered that the chilled packaging box P has not been input into the packaging box cleaning machine 1. At this time, the sensing unit 50 is connected to the booster pump 500, and the sensing unit 50 can stop the booster pump 500 from operating. Alternatively, the operation unit 60 may be connected to the sensing unit 50 to communicate with the booster pump 500. When the sensing unit 50 does not detect a chilled packaging box P, the operation unit 60 can stop the booster pump 500 from operating. Therefore, the nozzle can stop spraying water or cleaning water to reduce waste.

[0121] The present invention has been illustrated and described above with reference to preferred embodiments used to illustrate the principles of the invention. However, the present invention is not limited to the structure and application described above. Rather, those skilled in the art will understand that various changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
