Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and more specifically, to a pallet cleaning device and conveying equipment. Background Technology

[0002] Conveying equipment includes a frame and a conveyor belt rotatably mounted on the frame. Items to be conveyed are placed on the conveyor belt, which moves to transport them. Pallets are commonly used in manufacturing to transfer goods. A pallet includes a pallet plate and at least two support bars positioned beneath the pallet. The pallet plate supports the items. The support bars support the pallet, allowing for spacing between the pallet and the ground or conveyor belt, so that the pallet can be lifted and moved by forklifts, pallet trucks, or other handling equipment.

[0003] In industries such as dairy powder, pharmaceuticals, and food, pallets serve as crucial tools for product storage and transportation, and their cleanliness directly impacts product quality and safety. The support bars and their connections to the pallet, in particular, are key areas for cleaning due to their low profile and frequent contact with the ground. Currently, manual cleaning is commonly used for pallet cleaning. However, on production lines, where pallets are used frequently, manual cleaning is insufficient to meet the demands of high-speed operation, reducing overall production efficiency. Furthermore, the failure to promptly and effectively remove dust, particulate matter, or insects from the pallets increases the risk to product quality.

[0004] Therefore, the use of manual methods to clean pallets in related technologies reduces overall production efficiency. Utility Model Content

[0005] The main objective of this invention is to provide a pallet cleaning device and conveying equipment to solve the problem that manual pallet cleaning reduces overall production efficiency in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a pallet cleaning device is provided, which is installed on the frame of a conveyor.

[0007] Furthermore, the first spraying component includes a drive unit, a connecting rod, and an air knife. The drive unit is mounted on the frame, the connecting rod is connected to the rotating shaft of the drive unit, and the air knife is mounted on the connecting rod.

[0008] Furthermore, the air knife includes a first plate and a second plate disposed opposite to each other, and a transition plate connected between the first plate and the second plate. The first plate, the second plate, and the transition plate form a first spray nozzle, and an air inlet is provided on the first plate.

[0009] Furthermore, the distance between the first plate and the second plate gradually decreases along the direction closer to the first spray nozzle; and / or, both the first plate and the second plate are triangular, and the first plate and the second plate are arranged correspondingly, with the vertices of the triangles being arranged opposite to the first spray nozzle.

[0010] Furthermore, the pallet cleaning device also includes a counting detection element mounted on the frame, which is connected to the controller signal.

[0011] Furthermore, the pallet cleaning device also includes a third detection element installed on the frame. The third detection element is located upstream of the first detection element and is signal-connected to the controller to control the first spraying element to switch to the spraying position.

[0012] Furthermore, the pallet cleaning device also includes a cleaning roller brush rotatably mounted on the frame, positioned above the conveyor belt.

[0013] Furthermore, the cleaning roller brush includes a spindle rotatably mounted on a frame, connectors connected to the spindle, and brushes mounted on the connectors. Multiple connectors and brushes are arranged in a one-to-one correspondence, with the multiple connectors spaced apart circumferentially along the spindle. The brush includes a handle and bristles. The connectors include a first connecting piece, a second connecting piece, a third connecting piece, a first flange, and a second flange. The first connecting piece is connected to the spindle, the second connecting piece is opposite to the first connecting piece, and the third connecting piece is connected between the first and second connecting pieces. The first flange is mounted on the first connecting piece and extends toward the second connecting piece, and the second flange is mounted on the second connecting piece and extends toward the first connecting piece. The first and second flanges can cooperate with a stop on the brush handle, and the bristles pass between the first and second flanges.

[0014] Furthermore, the pallet cleaning device also includes a second spraying component mounted on the frame, the second spraying nozzle of the second spraying component being lower than the upper surface of the conveyor belt; and / or, the pallet cleaning device also includes a third spraying component mounted on the frame, the third spraying nozzle of the third spraying component being higher than the upper surface of the conveyor belt, and the third spraying component being located on one side of the conveyor belt.

[0015] According to another aspect of the present invention, a conveying device is provided, including a frame, a conveyor belt rotatably mounted on the frame, and a pallet cleaning device mounted on the frame. The pallet cleaning device is the pallet cleaning device described above. The conveyor belt consists of two belts spaced apart, and a first spraying component is oscillatingly mounted between the two conveyor belts.

[0016] Applying the technical solution of this utility model, a pallet cleaning device is installed on the frame of a conveyor. The pallet cleaning device includes: a first spraying component, a controller, a first detection component, and a second detection component. The first spraying component is swayably installed on the frame to have a spraying position and a clearance position. When the first spraying component is in the spraying position, the first spray nozzle of the first spraying component is higher than the upper surface of the conveyor belt of the conveyor. When the first spraying component is in the clearance position, the first spray nozzle of the first spraying component is lower than the upper surface of the conveyor belt. The controller is connected to the first spraying component. The first detection component is installed on the frame and located upstream of the first spraying component. The first detection component is signal-connected to the controller to control the first spraying component to switch to the clearance position. The second detection component is installed on the frame and located downstream of the first spraying component. The second detection component is signal-connected to the controller to control the first spraying component to switch to the spraying position. In this way, the first spraying component can spray and clean the pallet, especially the pallet support bars and the connection between the support bars and the pallet plate. When the first spraying component is in the spraying position, the first spray nozzle is higher than the conveyor belt of the conveyor equipment. This allows the first spray nozzle to effectively spray compressed air or other cleaning media onto the pallet as it passes, cleaning it. Simultaneously, when the first spraying component switches to the avoidance position, the first spray nozzle is lower than the conveyor belt, preventing collisions between the first spraying component and the pallet and ensuring smooth movement of the pallet during the cleaning process. The first and second detection components allow the pallet support bar to pass over the first spraying component. When the pallet support bar passes the first detection component upstream of the first spraying component, the first detection component detects that the support bar is approaching and controls the first spraying component to switch to the avoidance position, allowing the support bar to pass over it. When the pallet support bar passes the second detection component downstream of the first spraying component, the second detection component detects that the support bar has passed the first spraying component and controls the first spraying component to switch back to the spraying position, allowing it to continue spraying the pallet until the support bar of the next pallet passes the first detection component. By implementing the above-mentioned setup, not only is pallet cleaning efficiency significantly improved and manual intervention reduced, but the continuity of the production line is also enhanced, and downtime for maintenance is minimized, thereby increasing production efficiency. Therefore, the technical solution of this application effectively solves the problem in related technologies where manual pallet cleaning reduces overall production efficiency.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] In this embodiment, as Figure 1 and Figure 4As shown, a pallet cleaning device is mounted on the frame 51 of the conveyor equipment. The pallet cleaning device includes: a first spraying component 10, a controller, a first detection component 21, and a second detection component 22. The first spraying component 10 is pivotally mounted on the frame 51 to have a spraying position and a clearance position. When the first spraying component 10 is in the spraying position, the first spraying nozzle 134 of the first spraying component 10 is higher than the upper surface of the conveyor belt 52 of the conveyor equipment. When the first spraying component 10 is in the clearance position, the first spraying nozzle 134 of the first spraying component 10 is lower than the upper surface of the conveyor belt 52. The controller is connected to the first spraying component 10. The first detection component 21 is mounted on the frame 51 and located upstream of the first spraying component 10. The first detection component 21 is signal-connected to the controller to control the first spraying component 10 to switch to the clearance position. The second detection component 22 is mounted on the frame 51 and located downstream of the first spraying component 10. The second detection component 22 is signal-connected to the controller to control the first spraying component 10 to switch to the spraying position.

[0033] In this way, the first spraying component 10 can spray and clean the pallet, especially the support strips 62 and the connection between the support strips 62 and the pallet plate 61. When the first spraying component 10 is in the spraying position, the first spray nozzle 134 is higher than the conveyor belt 52 of the conveying equipment. This allows the first spray nozzle 134 to effectively spray compressed air or other cleaning media onto the pallet as it passes, cleaning it. Simultaneously, when the first spraying component 10 switches to the avoidance position, the first spray nozzle 134 is lower than the conveyor belt 52, preventing collisions between the first spraying component 10 and the pallet and ensuring smooth movement of the pallet during the cleaning process. By configuring the first detection element 21 and the second detection element 22, when the pallet support bar 62 passes the first detection element 21 located upstream of the first spraying element 10, the first detection element 21 can detect that the pallet support bar 62 is about to approach the first spraying element 10, and control the first spraying element 10 to switch to a clearance position so that the pallet support bar 62 can pass over the first spraying element 10. When the pallet support bar 62 passes the second detection element 22 located downstream of the first spraying element 10, the second detection element 22 can detect that the pallet support bar 62 has passed the first spraying element 10, and control the first spraying element 10 to switch to a spraying position so that the first spraying element 10 can continue to spray the pallet until the next pallet support bar 62 passes the first detection element 21. Through the above configuration, not only is the pallet cleaning efficiency significantly improved and manual intervention reduced, but the continuity of the production line is also improved, and downtime for maintenance is reduced, thereby improving production efficiency. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where manual cleaning of pallets reduces overall production efficiency.

[0034] In this embodiment, when the first spraying component 10 is in the spraying position, the first spraying nozzle 134 of the first spraying component 10 is higher than the upper surface of the conveyor belt 52 of the conveying equipment, and the height of the first spraying component 10 is lower than the lower surface of the pallet 61. Thus, when the first spraying component 10 is in the spraying position, the first spraying nozzle 134 is located below the pallet 61, and the first spraying nozzle 134 cleans the lower surface of the pallet 61, the support strip 62 of the pallet, and the connection between the support strip 62 and the pallet 61.

[0035] In this embodiment, the first spraying element 10 can output compressed air or other cleaning media to perform dry or wet cleaning on the tray. There are two first spraying elements 10 arranged at intervals.

[0036] like Figure 1 As shown, the first spraying component 10 includes a drive component 11, a connecting rod 12, and an air knife 13. The drive component 11 is mounted on the frame 51, the connecting rod 12 is connected to the rotating shaft of the drive component 11, and the air knife 13 is mounted on the connecting rod 12. In this way, the drive component 11 can provide power to the connecting rod 12. The rotation of the driving component 11's rotating shaft drives the connecting rod 12 to rotate, thereby causing the air knife 13 to swing, ensuring the stability of the air knife 13 during the swinging process. This optimized design makes the switching between the spraying position and the avoidance position of the first spraying component 10 more precise and efficient.

[0037] In this embodiment, the air knife 13 uses high-speed airflow generated by compressed air or a blower to form a uniform air curtain for blowing and cleaning the tray. When the first spraying component 10 is in the spraying position, the connecting rod 12 is perpendicular to the ground.

[0038] like Figure 3 As shown, the air knife 13 includes a first plate 131 and a second plate 132 arranged opposite to each other, and a transition plate 133 connecting the first plate 131 and the second plate 132. The first plate 131, the second plate 132, and the transition plate 133 form a first spray nozzle 134. An air inlet 135 is provided on the first plate 131. The structural design of the air knife 13 further enhances the cleaning effect. The first spray nozzle 134 formed by the first plate 131, the second plate 132, and the transition plate 133 not only optimizes the direction of airflow but also improves the concentration of airflow. By placing the air inlet 135 on the first plate 131, the airflow entering through the air inlet 135 can first impact the first plate 131 before being delivered to the first spray nozzle 134, making the airflow from the first spray nozzle 134 more uniform and the cleaning of the tray more thorough.

[0039] like Figure 3As shown, the distance between the first plate 131 and the second plate 132 gradually decreases along the direction approaching the first spray nozzle 134. This optimized design of the air knife 13, especially the gradual decrease in the distance between the first plate 131 and the second plate 132, allows the first spray nozzle 134 to generate stronger airflow pressure, effectively removing impurities from the tray surface, including inconspicuous dust, tiny particles, and potentially hidden insects, thereby ensuring high product quality and safety. Both the first plate 131 and the second plate 132 are triangular, and are arranged correspondingly, with the vertices of the triangles facing the first spray nozzle 134. Through the optimized shape of the first plate 131 and the second plate 132, the air knife 13 can blow out a more concentrated, efficient, and uniform airflow, which not only improves the efficiency of tray cleaning but also reduces energy waste during the cleaning process. The triangular arrangement of the first plate 131 and the second plate 132 increases the blowing area of ​​the first spray nozzle 134.

[0040] In other embodiments, the distance between the first plate 131 and the second plate 132 gradually decreases along the direction close to the first spray nozzle 134. Alternatively, both the first plate 131 and the second plate 132 are triangular, and the first plate 131 and the second plate 132 are arranged correspondingly, with the vertices of the triangles being arranged opposite to the first spray nozzle 134.

[0041] like Figure 4 As shown, the pallet cleaning device also includes a counting detector 24 mounted on the frame 51, which is connected to the controller. The counting detector 24 automatically identifies the number of support bars 62 on the passing pallet. When a pallet contains N support bars 62, the counting detector 24 detects the number of passing support bars 62 and accumulates N signals to determine that a pallet has completely passed. It then sends a signal to the controller, which in turn stops the pallet cleaning device to complete the cleaning of one pallet. This technology allows the pallet cleaning device to intelligently start or stop the cleaning process based on the number of pallet support bars 62, avoiding unnecessary continuous cleaning and resource waste.

[0042] In this embodiment, the counting detection element 24 includes a photoelectric switch and a PLC counter.

[0043] like Figure 4As shown, the pallet cleaning device also includes a third detection element 23 mounted on the frame 51. The third detection element 23 is located upstream of the first detection element 21 and is signal-connected to the controller to control the first spraying / sweeping element 10 to switch to the spraying / sweeping position. Positioning the third detection element 23 upstream of the first detection element 21 provides an additional rapid response mechanism. By setting the third detection element 23, the system can detect the arrival of the pallet before it enters the cleaning area and quickly initiate the cleaning program. Thus, when the pallet passes the third detection element 23, the third detection element 23 can detect the pallet's approach and activate the first spraying / sweeping element 10 to clean the pallet.

[0044] like Figure 1 As shown, the pallet cleaning device also includes a cleaning roller brush 30 rotatably mounted on the frame 51, positioned above the conveyor belt 52. The introduction of the cleaning roller brush 30 increases the cleaning capability of the pallet's upper surface, facilitating deep cleaning. The rotation of the cleaning roller brush 30 and its close contact with the pallet surface effectively removes dust, impurities, and microorganisms from the upper surface of the pallet's tray 61, improving not only the cleanliness of the pallet but also enhancing the product's hygiene standards.

[0045] like Figure 1 and Figure 2As shown, the cleaning roller brush 30 includes a spindle 31 rotatably mounted on a frame 51, a connector 32 connected to the spindle 31, and brushes 33 mounted on the connector 32. Multiple connectors 32 and brushes 33 are arranged in a one-to-one correspondence, with the multiple connectors 32 spaced apart circumferentially along the spindle 31. Each brush 33 includes a brush handle 331 and brush bristles 332. The connector 32 includes a first connecting piece 321, a second connecting piece 322, a third connecting piece 323, a first flange 324, and a second flange. The first connecting piece 321 is connected to the spindle 31, the second connecting piece 322 is disposed opposite to the first connecting piece 321, the third connecting piece 323 is connected between the first connecting piece 321 and the second connecting piece 322, the first flange 324 is disposed on the first connecting piece 321 and extends toward the second connecting piece 322, and the second flange is disposed on the second connecting piece 322 and extends toward the first connecting piece 321. The first flange 324 and the second flange can cooperate with the stop of the brush handle 331, and the bristles 332 pass through the space between the first flange 324 and the second flange. The design of the connector 32 and the brush 33 not only improves cleaning efficiency but also ensures easy assembly and disassembly of the brush 33 and the connector 32, facilitating the replacement and maintenance of the brush 33. The arrangement of the first connecting piece 321, the second connecting piece 322, the third connecting piece 323, the first flange 324, and the second flange allows the brush handle 331 to be positioned between the first connecting piece 321 and the second connecting piece 322. The first flange 324 and the second flange prevent the brush handle 331 from falling out from between the first connecting piece 321 and the second connecting piece 322, while also allowing the bristles 332 to pass through the space between the first flange 324 and the second flange, facilitating the cleaning of the tray. When the brush 33 needs to be replaced, the brush handle 331 can be easily removed from one side of the connector 32. The detachable design of connector 32 and brush 33 means that when brush 33 wears out or needs replacement, it can be easily replaced without stopping the machine or disassembling the entire cleaning unit. This design not only extends the service life of the cleaning unit and reduces maintenance costs, but also improves the adaptability and flexibility of the cleaning unit, enabling it to cope with changes in different cleaning needs.

[0046] In this embodiment, the spindle 31 is driven by a chain conveyor and a 24V DC motor, and is additionally equipped with a speed controller to adjust the rotational speed of the spindle 31 according to actual conditions. The two ends of the spindle 31 are fixed by bearing seats and brackets, and the bristles 332 contact and intersect with the upper surface of the tray. The cleaning roller brush 30 has a diameter of 16 cm and a length of 1.5 m. There are six connectors 32 and six brushes 33, evenly distributed on the spindle 31. The spindle 31 is a 5 cm diameter round steel bar, and the connectors 32 are detachably connected to the spindle 31 by fasteners.

[0047] like Figure 1As shown, the pallet cleaning device also includes a second spraying component 41 mounted on the frame 51. The second spraying nozzle of the second spraying component 41 is lower than the upper surface of the conveyor belt 52. Located below the conveyor belt 52, the second spraying component 41 effectively cleans the bottom of the pallet, removing any potentially hidden impurities. Furthermore, because the second spraying nozzle of the second spraying component 41 is lower than the upper surface of the conveyor belt 52, it can avoid pallet movement. The pallet cleaning device also includes a third spraying component 42 mounted on the frame 51. The third spraying nozzle of the third spraying component 42 is higher than the upper surface of the conveyor belt 52, and the third spraying component 42 is located on one side of the conveyor belt 52. Located on one side of the conveyor belt 52, the third spraying component 42 cleans the sides of the pallet, ensuring that every side of the pallet is thoroughly cleaned. The arrangement of the second and third spraying components 41 and 42 achieves comprehensive cleaning of the lower surface and sides of the pallet, ensuring a thorough cleaning strategy without blind spots. This not only improves the comprehensiveness and depth of cleaning but also reduces the risk of product quality being affected by the pallet's cleanliness, thus improving product safety.

[0048] In other embodiments, the pallet cleaning device further includes a second spraying member 41 disposed on the frame 51, the second spraying nozzle of the second spraying member 41 being lower than the upper surface of the conveyor belt 52. Alternatively, the pallet cleaning device further includes a third spraying member 42 disposed on the frame 51, the third spraying nozzle of the third spraying member 42 being higher than the upper surface of the conveyor belt 52, and the third spraying member 42 being located on one side of the conveyor belt 52.

[0049] In this embodiment, the second and third spray elements 41 and 42 have the same structure as the first spray element 10. The second and third spray elements 41 and 42 operate alternately in a pulse-triggered manner to reduce energy consumption and the overall air pressure. When the second spray element 41 is shut off, the blowing force of the third spray element 42 is increased. There are three second spray elements 41 spaced apart, and two third spray elements 42, with the two third spray elements 42 respectively located on both sides of the conveyor belt 52.

[0050] like Figure 1 As shown, this application also provides a conveying device, which includes a frame 51, a conveyor belt 52 rotatably mounted on the frame 51, and a pallet cleaning device mounted on the frame 51. The pallet cleaning device is the pallet cleaning device described above. Two conveyor belts 52 are spaced apart, and a first spraying member 10 is oscillatingly mounted between the two conveyor belts 52. Since the aforementioned pallet cleaning device can solve the problem of reduced overall production efficiency caused by manual pallet cleaning in related technologies, the conveying device with this pallet cleaning device can solve the same technical problem.

[0051] In this embodiment, the pallet cleaning device is integrated into the conveying equipment. Cleaning is performed by a first spraying element 10 between two spaced conveyor belts 52. This design not only automates pallet cleaning but also ensures the continuity and efficiency of the production line. The integrated cleaning and conveying system reduces the risk of production line interruptions, simplifies the operation process, reduces reliance on manual labor, and increases the automation level of the production line. This innovative design not only improves cleaning efficiency but also ensures stable production line operation, reduces maintenance and labor costs, and enhances overall production efficiency.

[0052] In some embodiments, the conveying device further includes a collector and a dust removal fan disposed below the pallet cleaning device. The collector is used to collect dust particles that fall during sweeping, and the dust removal fan is able to collect the dust particles collected by the collector. Alternatively, the conveying device further includes a water tray and a drain pipe disposed below the pallet cleaning device. The water tray is used to collect the falling cleaning medium, and the drain pipe is able to discharge the cleaning medium collected in the water tray.
