[0038] In the following description, the conveying direction referred to corresponds to Figure 2 The direction indicated by arrow A in the figure; the direction perpendicular to the conveying direction corresponds to the direction indicated by arrow B.

[0039] The embodiment of the present disclosure provides a transport system for conveying a pallet 10. The top surface of the pallet 10 includes a plurality of strip-shaped supporting surfaces 10a and a plurality of strip-shaped grooves 101 alternately arranged with the plurality of strip-shaped supporting surfaces 10a.

[0040] The transport system includes: a transport device and a cleaning device. The transport device is configured to transport the tray 10 along a transport direction, and during the transport of the tray 10, the extending directions of the plurality of strip-shaped supporting surfaces 10a and the plurality of strip-shaped grooves 101 are consistent with the transport direction.

[0041] The cleaning device is used to clean the tray 10 transported by the conveying device, and includes a brush head 1 arranged above the conveying device. The brush head 1 includes a bristle portion, and the bristle portion includes a plurality of short-hair portions 1B and a plurality of long-hair portions 1A arranged alternately with the plurality of short-hair portions 1B. The bristle length of the long-hair portion 1A is greater than the bristle length of the short-hair portion 1B, wherein the plurality of short-hair portions 1B are configured to be arranged in a one-to-one correspondence with the plurality of strip-shaped supporting surfaces 10a. The plurality of long-hair portions 1A are configured to be arranged in a one-to-one correspondence with the plurality of strip-shaped grooves 101, so that in the process of the conveying device transporting the tray 10, the short-hair portion 1B is opposite to the corresponding strip-shaped supporting surface 10a and moves relative to each other in the conveying direction to clean the corresponding strip-shaped supporting surface 10a, and the long-hair portion 1A is opposite to the corresponding strip-shaped groove 101 and moves relative to each other in the conveying direction to clean the corresponding strip-shaped groove 101.

[0042] A cleaning device is provided to clean the pallet 10 transported by the conveying device. The cleaning device includes a brush head 1 provided above the conveying device. The brush head 1 is provided with a plurality of long-hair portions 1A and short-hair portions 1B arranged alternately. In the process of the conveying device transporting the pallet 10 along the conveying direction, the long-hair portion 1A is made to form a relative movement relative to the strip groove 101, and the short-hair portion 1B is made to form a relative movement relative to the strip supporting surface 10a, so that the long-hair portion 1A cleans the corresponding strip groove 101, and the short-hair portion 1B cleans the corresponding strip supporting surface 10a. This arrangement is conducive to targeted cleaning of the surface of each position of the pallet 10, improving the cleaning force and cleaning range, and thus is conducive to efficient removal of the residual cigarette dust on the surface of the pallet 10. In addition, the cleaning process is carried out synchronously with the conveying process, and there is no need to stop the machine for cleaning, which is conducive to improving the transportation efficiency of the transportation system.

[0043] In some embodiments, along the conveying direction, the dimension of the upstream end of the long-haired portion 1A perpendicular to the conveying direction is smaller than the dimension of the downstream end perpendicular to the conveying direction. The direction from the upstream end of the long-haired portion 1A to the downstream end of the long-haired portion 1A is consistent with the conveying direction. The upstream end of the long-haired portion 1A is the end that first contacts the pallet 10 during the process of the conveying device conveying the pallet 10, and the downstream end of the long-haired portion 1A is the end that contacts the pallet 10 later during the process of the conveying device conveying the pallet 10.

[0044] The dimension of the upstream end of the long-hair portion 1A perpendicular to the conveying direction is made smaller than the dimension of the downstream end perpendicular to the conveying direction. During the conveying process, the tray 10 first passes through the upstream end of the long-hair portion 1A with a smaller dimension, and then passes through the downstream end with a larger dimension, which is conducive to the upstream end of the long-hair portion 1A smoothly entering the strip groove 101 and can guide the long-hair portion 1A, thereby facilitating the cleaning device to better clean the strip groove 101.

[0045] In some embodiments, along the conveying direction, the dimension of the upstream end of the long hair portion 1A perpendicular to the conveying direction is configured to be less than or equal to the width of the strip groove 101. Along the conveying direction, the dimension of the downstream end of the long hair portion 1A perpendicular to the conveying direction is configured to be greater than or equal to the width of the strip groove 101.

[0046] The upstream end of the long hair portion 1A is set to have a dimension perpendicular to the conveying direction that is smaller than or equal to the width of the groove 101, which is conducive to the upstream end of the long hair portion 1A smoothly entering the strip groove 101 and can guide the long hair portion 1A. The downstream end of the long hair portion 1A is set to have a dimension perpendicular to the conveying direction that is larger than or equal to the width of the strip groove 101, which is conducive to increasing the force of the bristles on the side wall of the strip groove 101, thereby facilitating the effective removal of soot attached to the side wall of the groove 101.

[0047] In some embodiments, the free ends of the bristles of the short-hair portion 1B are configured relative to the conveying device so that the free ends of the bristles of the short-hair portion 1B can contact the corresponding strip-shaped supporting surface 10a during the conveying device conveying the tray 10. The free ends of the bristles of the long-hair portion 1A are configured relative to the conveying device so that the free ends of the bristles of the long-hair portion 1A can contact the bottom surface 101a of the corresponding strip-shaped groove 101 during the conveying device conveying the tray 10.

[0048] This arrangement is beneficial to increasing the fit between the bristles and the strip supporting surface of the tray 10 and the bottom surface of the strip groove 101 during the process of the conveying device conveying the tray 10, thereby helping to strengthen the cleaning force of the cleaning device on the tray 10, thereby increasing the cleaning efficiency.

[0049] In some embodiments, the bristle portion is arranged in a direction perpendicular to the conveying direction. Figure 2 As shown, the plurality of long-hair portions 1A and the plurality of short-hair portions 1B are alternately arranged in a direction perpendicular to the conveying direction (ie, the direction indicated by arrow B), and the plurality of long-hair portions 1A and the plurality of short-hair portions 1B are aligned end to end in the conveying direction.

[0050] This arrangement helps the long-hair portion 1A and the short-hair portion 1B to clean the tray 10 synchronously, thereby helping to speed up the cleaning speed. In addition, this arrangement helps to reduce the size of the brush head 1, is easy to assemble and disassemble, and is also conducive to reducing costs.

[0051] In some embodiments, the cleaning device further comprises an adjustment bracket 5. The brush head 1 is mounted on the adjustment bracket 5. The adjustment bracket 5 is configured to adjust the position of the brush head 1 relative to the conveying device.

[0052] This arrangement is beneficial for enabling the adjustment bracket 5 to adaptively adjust the position of the brush head 1 according to the position of the tray 10 during the process of the conveying device conveying the tray 10 .

[0053] In some embodiments, the adjustment bracket 5 is configured to make the height of the brush head 1 relative to the conveying device adjustable, and / or make the position of the brush head 1 relative to the conveying device in a direction perpendicular to the conveying direction adjustable.

[0054] Making the height of the brush head 1 relative to the conveying device adjustable is helpful to adjust the relative position of the free end of the bristle portion and the top surface of the tray 10, maintaining the free end of the bristle portion always in contact with the surface of the tray 10 during the process of the conveying device conveying the tray 10, avoiding the existence of a gap between the bristle portion and the tray 10, so as to improve the cleaning effectiveness and efficiency.

[0055] For example, Figure 1 As shown, the adjustment bracket 5 may include an adjustment nut 53, a column 51 and a crossbeam 52. The column 51 is provided with a narrow slot (or a long hole) extending in the vertical direction. The crossbeam 52 extends into the narrow slot (or the long hole) and can move up and down along the narrow slot (or the long hole). The crossbeam 52 is fastened to the column 51 by adjusting the nut 53, so that the vertical position of the crossbeam 52 and the brush head 1 arranged on the crossbeam 52 relative to the column 51 can be adjusted, thereby changing the relative position of the brush head 1 and the conveying device. For another example, the column 51 of the adjustment bracket 5 can be configured to be retractable, and the crossbeam 52 and the brush head 1 thereon are driven to move up and down by the telescopic movement of the column 51, thereby changing the relative position of the brush head 1 and the conveying device.

[0056] Making the position of the brush head 1 relative to the conveying device in a direction perpendicular to the conveying direction adjustable is beneficial to maintaining the contact area between the free ends of the bristles of the brush portion and the surface of the tray 10. In the process of the conveying device conveying the tray 10, it is beneficial to avoid the problem that the long-hair portion 1A cannot be aligned with the strip groove 101 or the short-hair portion 1B cannot be aligned with the strip supporting surface 10a in the direction perpendicular to the conveying direction. This can avoid the brush head 1 from being misaligned with the tray 10 in the direction perpendicular to the conveying direction, thereby avoiding the brush head 1 from not cleaning the tray 10 properly, which is beneficial to improving the cleaning efficiency of the cleaning device.

[0057] For example, the adjustment bracket 5 may include Figure 1The column 51 and the beam 52 shown, the beam 52 includes a narrow groove extending in a direction perpendicular to the conveying direction, and the brush head 1 may include a protrusion that slidably cooperates with the narrow groove, so that the brush head 1 moves in a direction perpendicular to the conveying direction so that the short-hair portion 1B is opposite to the corresponding strip supporting surface 10a, and the long-hair portion 1A is opposite to the corresponding strip groove 101.

[0058] In some embodiments, the cleaning device further comprises a detection device. The detection device is configured to detect the relative position of the bristle portion and the conveying device. The adjustment bracket 5 is configured to adjust the position of the brush head 1 relative to the conveying device according to the detection information of the detection device.

[0059] This arrangement is beneficial for timely detecting the relative position between the free end of the bristle portion and the tray 10 during the process of the conveying device conveying the tray 10, for example, detecting whether there is a gap between the free end of the bristle portion and the tray 10 or whether the bristle portion and the tray 10 are aligned in a direction perpendicular to the conveying direction, so that the position of the brush head 1 can be adjusted in time by adjusting the bracket 5 to maintain the bristle portion to effectively clean the surface of the tray 10.

[0060] In some embodiments, the adjustment bracket 5 includes a driving device for driving the brush head 1 to move relative to the conveying device, and the detection device includes at least one of a first detection part, a second detection part and a third detection part.

[0061] The first detection part is configured to detect the relative position of the short hair part 1B and the strip supporting surface 10a during the process of the conveying device conveying the tray 10. The driving device is connected to the first detection part signal, and is configured to change the height of the brush head 1 relative to the conveying device according to the detection information of the first detection part so that the free end of the bristle of the short hair part 1B can contact the corresponding strip supporting surface 10a.

[0062] The second detection part is configured to detect the relative position of the long hair part 1A and the bottom surface 101a of the strip groove 101 during the process of the conveying device conveying the tray 10. The driving device is connected to the second detection part by signal, and is configured to change the height of the brush head 1 relative to the conveying device according to the detection information of the second detection part, so that the free ends of the bristles of the long hair part 1A can contact the bottom surface 101a of the corresponding strip groove 101.

[0063] The third detection part is configured to detect the position of the bristle part relative to the conveying device in a direction perpendicular to the conveying direction. The driving device is connected to the third detection part by signal and is configured to adjust the position of the brush head 1 relative to the conveying device in a direction perpendicular to the conveying direction according to the detection information of the third detection part, so that the short-hair part 1B is opposite to the corresponding strip-shaped supporting surface 10a, and the long-hair part 1A is opposite to the corresponding strip-shaped groove 101.

[0064] The first detection unit, the second detection unit or the third detection unit may include a distance sensor, a proximity switch, a photoelectric sensor, a laser sensor, etc. Among them, taking the first detection unit as an example:

[0065] For example, a controller may be provided, the first detection part may include a distance sensor, and the controller is configured to be connected to the distance sensor and the adjustment bracket 5 by signal, respectively. The distance sensor detects the distance between the short hair part 1B and the strip-shaped supporting surface 10a (hereinafter referred to as the first distance). If the distance detector detects that the first distance is greater than zero, the controller receives the signal sent by the distance detector, and controls the adjustment bracket 5 to drive the brush head 1 to move downward until the distance detector detects that the first distance is equal to zero.

[0066] For another example, the first detection unit may include a proximity switch. When the first distance is zero, the proximity switch is turned on, and the adjustment bracket 5 does not need to change the position of the brush head 1; when the first distance is greater than zero, the proximity switch is closed, the circuit is connected, and the adjustment bracket 5 drives the brush head 1 to move downward until the first distance is zero.

[0067] In some embodiments, the adjustment bracket 5 includes: a column 51 and a crossbeam 52. The column 51 is fixed relative to the conveying device. The crossbeam 52 is installed on the column 51 in a changeable position relative to the column 51, and the brush head 1 is installed on the crossbeam 52.

[0068] The column 51 can be configured to be retractable, in which case the aforementioned driving device can include a driving cylinder or a motor for driving the column 51 to be retracted. A kinematic pair can be provided between the crossbeam 52 and the brush head 1 to enable the two to move relative to each other in a direction perpendicular to the conveying direction, in which case the aforementioned driving device can include a driving cylinder or a motor for driving the kinematic pair to move relative to each other.

[0069] The adjustment bracket 5 is configured to include a column 51 and a crossbeam 52, and has a simple structure, which facilitates the adjustment bracket 5 to stably adjust the brush head 1 to move up and down, or move in a direction perpendicular to the conveying direction. In addition, this configuration is also conducive to maintaining the brush head 1 from tilting or shaking during movement, thereby maintaining the height of the free ends of the bristles of the bristle part to be consistent, thereby facilitating the avoidance of uneven cleaning.

[0070] The following combination Figures 1 to 3 The transportation system of the embodiment of the present disclosure is described in detail. For simplicity of description, direction A (i.e. Figure 2 The direction indicated by the arrow A in the middle refers to the conveying direction of the conveying device conveying the tray 10, and the direction B (i.e. Figure 2 The direction indicated by the arrow B in the figure represents the direction perpendicular to the conveying direction.

[0071] like Figure 1As shown, the transport system includes a conveying device, a cleaning device and a detection device. The conveying device includes a roller conveyor 20, and the roller conveyor 20 conveys the pallet 10 along the direction A to move the pallet 10 close to the cleaning device. The cleaning device includes a brush head 1 and an adjustment bracket 5, and the brush head 1 is installed on the adjustment bracket 5 to adjust the position of the brush head 1 by adjusting the bracket 5, so as to maintain the effectiveness of the brush head 1 in cleaning the pallet 20. The detection device includes a first detection part and a second detection part, the first detection part detects the distance between the short-hair part 1B and the strip-shaped supporting surface 10a, and the second detection part detects the distance between the long-hair part 1A and the bottom surface 101a of the strip-shaped groove 10. The detection device is provided to monitor the position of the brush head 1 relative to the pallet 10 in real time, so as to change the position of the brush head 1 in time when the bristle part does not effectively clean the pallet 10, so as to improve the cleaning efficiency of the pallet 10.

[0072] The two columns 51 of the adjustment bracket 5 are respectively arranged on both sides of one end of the roller conveyor 20 along the direction A along the direction B, and the distance between the two columns 51 and the roller conveyor 20 along the direction B is equal. The two ends of the crossbeam 52 of the adjustment bracket 5 are installed between the two columns 51 through the adjustment nut 53. The column 51 includes a narrow slot extending up and down, and the crossbeam 52 is inserted into the narrow slot and can adjust the height. The adjustment nut 53 is used to fix the crossbeam 52 in the narrow slot. Loosen the adjustment nut 53, and the adjustment nut 53 can slide in the narrow slot; tighten the adjustment nut 53, and the adjustment nut 53 is fixedly connected to the column 51.

[0073] The brush head 1 includes a bristle portion and a base 12. Figure 1 and Figure 2 As shown, the base 12 is a rectangular parallelepiped, the upper surface of the base 12 is fixedly connected to the crossbeam 52 of the adjustment bracket 5, and the base 12 is located below the middle of the crossbeam 52. The upper ends of the bristles of the bristle part are fixedly connected to the lower surface of the base 12. The lower end of the bristle part is a free end, and the bristles of the bristle part are all arranged vertically.

[0074] In this embodiment, the pallet 10 conveyed by the roller conveyor 20 includes 5 strip-shaped supporting surfaces 10a and 4 strip-shaped grooves 101, so that the bristle portion includes 5 short-hair portions 1B and 4 long-hair portions 1A. Along direction B, the short-hair portions 1B and the long-hair portions 1A are arranged alternately in sequence, and the bristle length of the short-hair portion 1B is two-thirds of the bristle length of the long-hair portion 1A. In other embodiments not shown in the figure, the bristles of the short-hair portion 1B and the long-hair portion 1A can also be set to other lengths to adapt to different models of pallets 10.

[0075] The pallet 10 is located in the middle of the conveying surface of the roller conveyor 20 along direction B, so that when the conveying device conveys the pallet 10, each short-hair portion 1B corresponds to a strip-shaped supporting surface 10a, and each long-hair portion 1A corresponds to a strip-shaped groove 101. In direction A, when the roller conveyor 20 conveys the pallet 10, it is possible to achieve: the short-hair portion 1B and the corresponding strip-shaped supporting surface 10a move relative to each other to clean the corresponding strip-shaped supporting surface 10a; the long-hair portion 1A and the corresponding strip-shaped groove 101 move relative to each other to clean the corresponding strip-shaped groove 101.

[0076] like Figure 3 As shown, both the short-hair portion 1B and the long-hair portion 1A include 5 rows of bristles. Among them, along direction A, the long-hair portion 1A includes a guide section 1A-1 and a main section 1A-2. The guide section 1A-1 is three rows of bristles at the upstream end of the long-hair portion 1A, and its width is less than the width of the strip groove 101. The main section 1A-2 is two rows of bristles at the downstream end of the long-hair portion 1A, and its width is greater than the width of the strip groove 101. In the process of the roller conveyor 20 conveying the pallet 10 along direction A, each guide section 1A-1 first enters the corresponding strip groove 101, thereby playing a guiding role. Subsequently, the main section 1A-2 also enters the strip groove 101, and at the same time cleans the bottom surface 101a and the side wall of the strip groove 101, which is beneficial to improve the cleaning effect.

[0077] The crossbeam 52 of the adjustment bracket 5 moves up and down in the vertical direction on the two columns 51 through the adjustment nut 53. If there is a gap between the short-hair portion 1B and the strip-shaped supporting surface 10a, loosen the adjustment nuts 53 on both sides of the crossbeam 52 so that the crossbeam 52 drives the brush head 1 to move downward until the free ends of the bristles of the short-hair portion 1B can contact the corresponding strip-shaped supporting surface 10a. Alternatively, if there is a gap between the long-hair portion 1A and the bottom surface 101a of the strip-shaped groove 101, loosen the adjustment nuts 53 on both sides of the crossbeam 52 so that the crossbeam 52 drives the brush head 1 to move downward until the free ends of the bristles of the long-hair portion 1A can contact the bottom surface 101a of the corresponding strip-shaped groove 101. This arrangement is conducive to the cleaning device to effectively clean the top surface of the tray 10.

[0078] According to the following Figure 1 and Figure 2 Detailed description of the process of transporting pallets by the transport system:

[0079] First, loosen the adjusting nut 53, adjust the crossbeam 52 to the preset position, and then tighten the adjusting nut. At the preset position, the distance from the free end of the short bristle portion of the brush head 1 to the conveying surface of the roller conveyor 20 is equal to or greater than the distance from the strip supporting surface of the tray 10 placed on the conveying surface to the conveying surface.

[0080] Subsequently, the tray 10 is placed at a middle position along the direction B on the conveying surface of the roller conveyor 20 , and the tray 10 is moved to below the brush head 1 of the cleaning device by the roller conveyor 20 .

[0081] When the roller conveyor 20 conveys the tray 10 close to the brush head 1, the upstream end of the long-hair portion 1A first enters the corresponding strip groove 101 and cleans the bottom surface 101a of the strip groove 101. At the same time, the upstream end of the short-hair portion 1B cleans the corresponding strip supporting surface 10a.

[0082] The roller conveyor 20 continues to convey the tray 20 so that the downstream end of the long-hair portion 1A also enters the corresponding strip groove 101 and cleans the bottom surface 101a and the side wall of the strip groove 101 at the same time. At the same time, the downstream end of the short-hair portion 1B also starts to clean the corresponding strip supporting surface 10a.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution for protection requested by the present disclosure.
