Description

Technical Field

[0001] The present disclosure relates to the technical field of tobacco production, and particularly to a tray tobacco dust cleaning device and control method, and a tobacco production line. Background Art

[0002] At present, the high-bay warehouse for cut tobacco uses stackers for picking and placing, shuttle cars for transferring, and roller conveyors for transporting to complete the inbound and outbound operations of tobacco bales. The entire operation process is clear, with a high degree of automation and stable equipment operation. However, there are the following problems in actual production:

[0003] 1. During the inbound and outbound operations of tobacco bales, the tobacco dust on the bales will fall onto the surface of the empty trays. After long-term adhesion and accumulation, there will be a large amount of tobacco dust remaining on the surface.

[0004] 2. A large amount of tobacco dust remains on the trays for a long time, which is likely to breed tobacco insects and cause mildew on the trays, seriously affecting the quality of tobacco leaves.

[0005] 3. During the conveying process of tobacco bales in and out of the warehouse, the tobacco leaves and tobacco dust remaining on the trays often fall onto the equipment and facilities along the way, affecting the photoelectric detection function of the equipment, causing the equipment to stop, and in severe cases, even causing failures.

[0006] 4. The original manual blowing operation cannot effectively collect the garbage after blowing, and the centralized treatment is difficult, with extremely high labor costs.

[0007] 5. Since the tobacco leaves are packaged in two ways, namely gunny bags and cartons, the amount of tobacco dust falling from the tobacco leaves packed in gunny bags onto the trays is more than twice that of the tobacco leaves packed in cartons. Therefore, more air is needed for blowing to clean the tobacco dust.

[0008] The above situations will cause problems such as material loss in the cut tobacco warehouse, equipment stoppage, shutdown, and wear, and will also increase labor costs, etc. Summary of the Invention

[0079] The present disclosure will be described in detail below. In the following paragraphs, different aspects of the embodiments are defined in more detail. Each aspect so defined can be combined with any other one or more aspects, unless explicitly stated that they cannot be combined. In particular, any feature considered to be preferred or advantageous can be combined with one or more other features considered to be preferred or advantageous.

[0080] The terms "first", "second", etc. used in the present disclosure are only for convenience of description to distinguish different components with the same name, and do not indicate a sequence or primary-secondary relationship.

[0081] In the description of the present disclosure, the orientation or positional relationships indicated by "upper", "lower", "left", "right", "front", "rear", "inner" and "outer" are defined based on the orientation of the operator sitting in the cab. This is only for the convenience of describing the present disclosure, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the protection scope of the present disclosure.

[0082] As Figures 1 to 11 , the present disclosure provides a tray tobacco dust cleaning device for cleaning the tobacco dust or dust remaining on the tray during use. In some embodiments, the tray tobacco dust cleaning device includes: a first bracket 20 and a purging component. As Figure 1 and Figure 5 shown, the first bracket 20 straddles the conveyor 10 for conveying the tray 100, and a passage for the tray 100 to pass through is formed between the first bracket 20 and the conveyor 10. For example, the conveyor can be a roller conveyor. The purging component includes an air guide pipe group and a plurality of air blowing nozzles 27. The air guide pipe group is configured to supply air to the plurality of air blowing nozzles 27. The plurality of air blowing nozzles 27 are installed on the first bracket 20 and are arranged above the conveyor 10 in the width direction of the conveyor 10. The air blowing nozzles 27 are configured to blow air towards the tray 100 when the tray 100 passes by. When the purging component is installed on the conveyor, the position of the air blowing nozzles 27 should be at an appropriate linear distance from the inner bottom surface of the tray 100, and the control spacing is between x centimeters.

[0083] As Figure 2 shown, the air blowing nozzle 27 includes an air guiding part 271 and a nozzle part 272. One end of the air guiding part 271 is communicated with the air guide pipe group, and the other end is connected to the nozzle part 272. A plurality of air blowing ports 273 are provided at the end of the nozzle part 272 away from the air guiding part 271 to blow out gas outward.

[0084] Preferably, the first bracket 20 can be designed as a structure with adjustable height, and the first bracket 20 is movably arranged along the length direction of the conveyor 10 in the installation plane. In this way, by adjusting the position of the first bracket 20, the distance between the air blowing nozzles 27 and the tray 100 can be x centimeters, and the blowing angle is α°.

[0085] This embodiment can automatically purge the tray. By blowing air, it can effectively and centrally remove sundries such as tobacco dust and dirt in the tray, preventing a large amount of tobacco dust from remaining in the tray, so as to avoid the growth of tobacco insects in the tray and the mildew of the tray, which may affect the quality of tobacco leaves. Moreover, it can also prevent the tobacco leaves and tobacco dust remaining on the tray from falling onto the equipment or facilities along the way during the inbound and outbound process of the tobacco bales, affecting the photoelectric detection function and preventing equipment stagnation or failure. In addition, it can improve the automation degree of tray cleaning and reduce labor costs. Therefore, this embodiment can effectively solve the problems of ensuring the quality of tobacco leaf production, reducing equipment failures, reducing material losses, and reducing labor costs.

[0086] As Figure 1 、 5 and shown in 6, the air guiding pipe group includes a first main air pipe 21, a second main air pipe 23, a plurality of first branch air pipes 22 and a plurality of second branch air pipes 24. The plurality of first branch air pipes 22 are all connected to the first main air pipe 21. For example, the plurality of first branch air pipes 22 are all connected to one end of the first main air pipe 21, and the other end of the first main air pipe 21 is used for air intake. The plurality of second branch air pipes 24 are all connected to the second main air pipe 23. For example, the plurality of second branch air pipes 24 are all connected to one end of the second main air pipe 23, and the other end of the second main air pipe 23 is used for air intake.

[0087] The plurality of air blowing nozzles 27 include a first nozzle group and a second nozzle group. The plurality of air blowing nozzles 27 in the first nozzle group are respectively connected to the ends of the plurality of first branch air pipes 22 far from the first main air pipe 21, and the plurality of air blowing nozzles 27 in the second nozzle group are respectively connected to the ends of the plurality of second branch air pipes 24 far from the second main air pipe 23.

[0088] Preferably, the first main air pipe 21 can be arranged above the second main air pipe 23 with a spacing, which is more beneficial for pipeline layout. The numbers of the plurality of air blowing nozzles 27 in the first nozzle group can be 1, 3, 5, 7,... 2n - 1, 2n + 1, and the numbers of the plurality of air blowing nozzles 27 in the second nozzle group can be 2, 4, 6,... 2n - 2, 2n, 2n + 2.

[0089] This embodiment sets two groups of air blowing nozzles 27 and sets independent air pipes for each group of air blowing nozzles 27. On the one hand, it can reduce the requirements for the air supply volume of the air source, and on the other hand, it is also conducive to realizing the independent air supply of the two groups of air blowing nozzles 27, providing conditions for changing the air supply volume.

[0090] In some embodiments, such as Figure 1 、 5As shown in FIGS. 5 and 6, the purging component further includes two regulating valves 25 which are respectively arranged on the first main air pipe 21 and the second main air pipe 23 and are configured to respectively regulate the gas flow rates passing through the first main air pipe 21 and the second main air pipe 23.

[0091] This embodiment can adjust the gas flow rate according to the amount or difficulty of the tobacco dust to be purged in the tray to ensure the tray cleaning effect, with flexible use and strong applicability. Moreover, in the case of insufficient blowing or incomplete purging of the tray 100, the regulating valve 25 on the main air pipe that needs to work in the first main air pipe 21 and the second main air pipe 23 is adjusted to regulate the blowing volume.

[0092] In some embodiments, as Figure 1 、 5 As shown in FIGS. 5 and 6, the purging component further includes two on-off valves 26 which are respectively arranged on the first main air pipe 21 and the second main air pipe 23 and are configured to respectively regulate the on-off of the gas passing through the first main air pipe 21 and the second main air pipe 23. For example, the on-off valve 26 can be an electromagnetic valve.

[0093] This embodiment can independently control the two on-off valves 26 according to the purging requirements to realize the independent air supply of the two groups of blowing nozzles 27 and can change the blowing volume. For example, if the tray 100 to be purged is used to carry tobacco leaves in gunny bags, the amount of tobacco dust remaining on the tray 100 is large and a large blowing volume is required, then both on-off valves 26 are in the on state. If the tray 100 to be purged is used to carry tobacco leaves in cardboard boxes, the amount of tobacco dust remaining on the tray 100 is small and a small blowing volume is required, and one of the two on-off valves 26 is in the on state and the other is in the off state. At this time, only half of the blowing nozzles 27 blow air, which can prevent gas waste. Thus, the states of the two on-off valves 26 can be determined according to the type of the tray 100.

[0094] In some embodiments, as Figure 1 and Figure 7As shown in the figure, the tray tobacco dust cleaning device further includes: a first position detection component 60, located on the tray inlet side of the first bracket 20, configured to detect the position of the tray 100. For example, an optoelectronic detection sensor, a laser sensor, etc. can be used; a barcode reader 50 is located on the tray inlet side of the first bracket 20, configured to read the barcode 100' on the tray 100; and a controller, electrically connected to the first position detection component 60 and the barcode reader 50, configured to cause the barcode reader 50 to read the barcode 100' when the first position detection component 60 detects the tray 100. For example, the barcode 100' can be read by radio frequency, and the blowing air volume requirement of the tray 100 is determined through the barcode 100', so as to control the on-off state of the two on-off valves 26 according to the blowing air volume requirement. It can be determined whether the tray 100 is used to carry tobacco leaves in gunny bags or tobacco leaves in cartons through the read barcode information. The controller can be integrated into the main controller of the conveyor 10 or can be set separately.

[0095] In some embodiments, as Figure 1 and Figure 7 shown, the tray tobacco dust cleaning device further includes: a second position detection component 70, for example, an optoelectronic detection sensor, a laser sensor, etc. The second position detection component 70 is located on the tray inlet side of the first bracket 20 and on the side of the first position detection component 60 close to the first bracket 20, configured to detect the position of the tray 100; wherein, the controller is electrically connected to the second position detection component 70, configured to cause the two on-off valves 26 to switch to the on state as needed when the second position detection component 70 detects the tray 100, so as to turn on the blowing component.

[0096] In this embodiment, when the tray 100 is transmitted to the position of the first position detection component 60 close to the purging component, the information of the barcode 100' can be read by the barcode reader 50 first to determine the working state of the two on-off valves 26; then when the tray 100 continues to be transmitted to the position where the second position detection component 70 is located, the on-off valve 26 that needs to be opened is switched to the on state to turn on the blowing component for purging. Thus, this embodiment can accurately determine the opening timing of the blowing component when the tray 100 is about to arrive, so as to effectively purge the tray.

[0097] In some embodiments, as Figure 1 and Figure 7 shown, the tray tobacco dust cleaning device further includes: a second position detection component 70, located on the tray inlet side of the first bracket 20, configured to detect the position of the tray 100; and a controller, electrically connected to the second position detection component 70, configured to turn on the purging component when the second position detection component 70 detects the tray 100. This embodiment can accurately determine the opening timing of the blowing component when the tray 100 is about to arrive, so as to effectively purge the tray.

[0098] In some embodiments, as Figure 1 and Figure 8 shown, the tray tobacco dust cleaning device further includes: a third position detection component 70', such as a photoelectric detection sensor, a laser sensor, etc., the third position detection component 70' is located on the tray removal side of the first bracket 20, and is configured to detect the position of the tray 100; and a controller, electrically connected to the third position detection component 70', and is configured to close the purging component to stop purging when the third position detection component 70' detects the tray 100. This embodiment can timely close the purging component after the tray purging is completed to save air supply.

[0099] In some embodiments, as Figure 1 and Figure 6 shown, the first bracket 20 includes: two columns 20', respectively located on both sides of the conveyor 10 in the width direction, and can be fixed to the floor, for example; and a mounting back plate, the mounting back plate extends along the width direction of the conveyor 10, as Figure 9 shown, the mounting back plate includes a first plate segment 83 and a second plate segment 81, the first plate segment 83 is fixed between the two columns 20', in the vertical plane where the length direction of the conveyor 10 is located, the second plate segment 81 is swingably connected to the first plate segment 83 through a rotating shaft 82, and a plurality of air blowing nozzles 27 are installed at intervals along the width direction on the second plate segment 81. The tray tobacco dust cleaning device further includes a driving component, which is configured to drive the second plate segment 81 to freely swing relative to the first plate segment 83 during the purging process to change the air blowing direction of the air blowing nozzles 27. For example, the driving component and the air blowing nozzles 27 are arranged on different sides of the mounting back plate.

[0100] This embodiment can drive the second plate segment 81 to swing through the driving component to realize the synchronous swing of the plurality of air blowing nozzles 27, and can synchronously change the air blowing direction of the plurality of air blowing nozzles 27. It can not only timely adjust the air blowing direction along with the conveyance of the tray 100 to effectively purge different parts of the tray, but also repeatedly purge the tray from different angles through the swing of the air blowing nozzles 27, which can improve the cleaning effect of the tray 100.

[0101] In some embodiments, as Figure 9 shown, the driving component includes: a swinging component 90, which is swingably arranged around its own axis, the swinging component 90 includes: a rotating main body 91 and a plurality of protruding parts 92 connected to the side wall of the rotating main body 91 at intervals along the circumferential direction, the outer wall of the protruding part 92 is arc-shaped, such as circular arc-shaped, the outer wall of one of the protruding parts 92 is in tangential contact with the second plate segment 81, and a recessed part 93 is formed between adjacent protruding parts 92, and the recessed part 93 can also be arc-shaped, such as circular arc-shaped; and a power component 80, which is configured to provide power for the swing of the swinging component 90, and the power component can be a motor or a motor, etc., for example. As Figure 9As shown, there are four more protruding parts 92 on the side wall of the rotating body 91.

[0102] As Figure 10 shown, when the second plate segment 81 and the swinging member 90 are in the first state A, it is represented by a dotted line. When the second plate segment 81 and the swinging member 90 are in the second state B, it is represented by a solid line. In the first state A and the second state B, the angular positions of the second plate segment 81 are different so that the plurality of air blowing nozzles 27 obtain different air blowing angles.

[0103] This embodiment can make the second plate segment 81 lean against one of the protruding parts 92 obliquely. When the power component 80 drives the swinging member 90 to rotate, the position change of the protruding part 92 can push the second plate segment 81 to swing, driving the plurality of air blowing nozzles 27 to blow at different angles. This embodiment has a simple structure, can provide a stable and smooth driving force for the second plate segment 81, and can make the movement of the second plate segment 81 more continuous, thereby smoothly changing the air blowing direction to improve the purging effect of the tray 100.

[0104] In some embodiments, as Figure 1 、 4 and shown in 5, the tray tobacco dust cleaning device further includes: a second bracket 30 provided at the bottom of the conveyor 10; and a collection tray 40 placed on the second bracket 30 and located between the second bracket 30 and the conveyor 10, configured to collect the tobacco dust purged by the purging component. For example, the collection tray 40 includes a tray body 41 and a handle 42. The tray body 41 is used to hold the tobacco dust, and the handle 42 is provided on the outer side wall of the tray body 41, which is easy to pull out the collection tray 40 to pour out the internal tobacco dust or perform subsequent processing. The collection tray 40 should be as close as possible to the conveyor 10 so that the collection tray 40 can more effectively collect the purged debris.

[0105] This embodiment can centrally collect the tobacco dust purged from the tray through the collection tray 40, which is easy for subsequent processing, and can also prevent the blown tobacco dust from falling on the ground and polluting the production environment, or preventing the tobacco dust from falling into the equipment and affecting the normal operation of the equipment.

[0106] Secondly, as Figure 1 shown, the present disclosure provides a tobacco production line, including: a conveyor 10 configured to convey the tray 100; and the tray tobacco dust cleaning device of the above embodiment; wherein, the first bracket 20 spans across the conveyor 10 and forms a passage for the tray 100 to pass through between the first bracket 20 and the conveyor 10.

[0107] This embodiment can automatically purge the pallets transported on the conveyor 10, and effectively remove the tobacco dust, dust and other debris in the pallets by blowing, so as to prevent a lot of tobacco dust from remaining in the pallets, so as to prevent the pallets from breeding tobacco insects and causing the pallets to mold and affect the quality of tobacco leaves; it can also prevent the tobacco leaves and tobacco dust remaining on the pallets during the process of cigarette packs entering and leaving the warehouse from falling onto the equipment or facilities along the way to affect the photoelectric detection function, and prevent equipment from stagnating or malfunctioning; in addition, it can also improve the automation of pallet cleaning and reduce labor costs. This tobacco production line can purge the pallets regularly or when needed during non-production periods, and can also purge the pallets during the transportation process after they are used during the production process, so as to keep the pallets clean.

[0108] Combine the following Figures 1 to 11 To illustrate the cleaning method of the tray in the present disclosure.

[0109] When the conveyor 10 conveys an empty pallet and triggers the first position detection component 60, the first position detection component 60 is used to trigger the barcode reader 50 to start reading the barcode 100' of the pallet 100, and to determine whether the pallet 100 is carrying tobacco leaves in sacks or in cartons by reading the barcode 100', and to select whether to open both solenoid valves 26 or only one of the solenoid valves 26 when blowing air with the purge component. If the pallet 100 is a tobacco leaf in a carton, when the pallet 100 continues to be transported forward and triggers the second position detection component 70, only one of the solenoid valves 26 is opened to purge the tobacco leaves; if the pallet 100 is a tobacco leaf in a sack, when the pallet 100 continues to be transported forward and triggers the second position detection component 70, both solenoid valves 26 are opened at the same time for purge.

[0110] During the purging process, the power component 80 is controlled to work to drive the swing component 90 to rotate, thereby forcing the second plate segment 81 to swing, and then driving the multiple air blowing nozzles 27 to swing to purge the cigarette dust on the tray 100 from different angles, and the purged cigarette dust falls into the collection tray 40. The purging component stops blowing until the tray 100 leaves the third position detection component 70'.

[0111] If the air is insufficient or not purged thoroughly during the purging process, the air volume can be adjusted by adjusting the regulating valve 25 .

[0112] Finally, the present disclosure also provides a control method for the tray cigarette dust cleaning device of the above embodiment, further comprising:

[0113] Step 110, detecting the position of the tray 100 by the second position detecting component 70, the second position being located at the tray moving-in side of the first bracket 20;

[0114] Step 120: When the second position detecting member 70 detects the tray 100 through the controller, the purging member is turned on.

[0115] This embodiment can accurately determine the timing when the tray 100 is about to reach the purging member, and turn on the purging member to blow air, realizing the automatic purging of the tray 100 and ensuring the purging effect.

[0116] In some embodiments, the air guiding pipe group includes independent first main air pipe 21 and second main air pipe 23, and the plurality of air blowing nozzles 27 include a first nozzle group and a second nozzle group. The first main air pipe 21 is configured to supply air to the first nozzle group, and the second main air pipe 23 is configured to supply air to the second nozzle group. The purging member further includes two on-off valves 26 respectively arranged on the first main air pipe 21 and the second main air pipe 23; the control method further includes:

[0117] Step 102: Detect the position of the tray 100 through the first position detecting member 60. The first position detecting member 60 is located on the tray moving-in side of the first bracket 20 and on the side of the second position detecting member 70 away from the first bracket 20;

[0118] Step 104: When the first position detecting member 60 detects the tray 100, read the bar code 100' on the tray 100 through the bar code reader 50. The bar code 100' can be arranged on the outer side wall of the tray 100;

[0119] Step 106: Determine the air blowing volume requirement of the tray 100 through the bar code 100', so as to control the on-off states of the two on-off valves 26 according to the air blowing volume requirement.

[0120] Among them, steps 102-104 are executed in sequence. Steps 102 and 110 can be detected in real time during the purging process to detect whether there is a tray 100 passing through; steps 104 and 106 can be executed before step 120.

[0121] This embodiment can, when the tray 100 is transferred to the position of the first position detecting member 60 close to the purging member, first read the information of the bar code 100' through the bar code reader 50 to determine the working states of the two on-off valves 26; then when the tray 100 continues to be transferred to the position of the second position detecting member 70, switch the on-off valve 26 to be turned on to turn on the air blowing member for purging. Thus, this embodiment can accurately determine the opening timing of the air blowing member when the tray 100 is about to arrive, thereby effectively purging the tray.

[0122] In some embodiments, step 106 determining the air blowing volume requirement of the tray 100 through the bar code 100' to control the on-off states of the two on-off valves 26 includes:

[0123] Determine the object carried by the tray 100 to be purged. If the tray 100 to be purged is used to carry tobacco leaves in sacks, since the amount of leaked tobacco dust is large and a large amount of blowing air is required, both on-off valves 26 are turned on. If the tray 100 to be purged is used to carry tobacco leaves in cartons, since the amount of leaked tobacco dust is small and a small amount of blowing air is required, one of the two on-off valves 26 is turned on and the other is turned off.

[0124] This embodiment can determine the amount of blowing air required according to the object carried by the tray 100, so that both groups of blowing nozzles 27 are turned on, or only one group of blowing nozzles 27 is selected to be turned on, so as to meet the cleaning requirements of the tray 100 and improve the tray cleaning effect.

[0125] In some embodiments, the air guiding pipe group includes an independent first main air pipe 21 and a second main air pipe 23.

The purging component further includes two regulating valves 25 respectively arranged on the first main air pipe 21 and the second main air pipe 23; the control method further includes:

[0126] In the case of insufficient blowing or the tray 100 not being purged cleanly, adjust the regulating valve 25 on the main air pipe that needs to work in the first main air pipe 21 and the second main air pipe 23 to adjust the amount of blowing air.

[0127] This embodiment can flexibly adjust the amount of blowing air according to the cleaning requirements to obtain a better cleaning effect.

[0128] In some embodiments, the control method further includes:

[0129] Step 130: Detect the position of the tray 100 through the third position detection component 70', and the third position detection component 70' is located on the tray removal side of the first bracket 20;

[0130] Step 140: When the third position detection component 70' detects the tray 100, turn off the purging component to stop purging.

[0131] Among them, step 130 can detect in real time during the purging process whether there is a tray that has been purged, and step 140 can be executed after step 120. This embodiment can accurately judge the actual situation where the tray 100 has completed purging. If the purging is completed, the purging component is timely turned off to save the air supply.

[0132] In some embodiments, the first bracket 20 includes: a mounting backplate extending along the width direction of the conveyor 10, the mounting backplate including a first plate segment 83 and a second plate segment 81, the first plate segment 83 being fixedly arranged, and the second plate segment 81 being swingably connected to the first plate segment 83 in the plane where the length direction of the conveyor 10 is located, and a plurality of air blowing nozzles 27 are mounted on the second plate segment 81; the tray tobacco dust cleaning device further includes a driving component; the control method further includes:

[0133] Step 150, after the second position detecting component 70 detects the tray 100, turn on the driving component to drive the second plate segment 81 to swing relative to the first plate segment 83 during the purging process, so as to change the air blowing direction of the air blowing nozzles 27.

[0134] Among them, step 150 can be executed during the execution of step 120.

[0135] This embodiment can drive the second plate segment 81 to swing through the driving component to realize the synchronous swing of the plurality of air blowing nozzles 27, and can synchronously change the air blowing directions of the plurality of air blowing nozzles 27. It can not only timely adjust the air blowing direction with the conveyance of the tray 100 to effectively purge different parts of the tray, but also repeatedly purge the tray from different angles through the swing of the air blowing nozzles 27, which can improve the cleaning effect of the tray 100.
