It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] Example

[0040] For details, please refer to Figure 1 and Figure 2 A device for detecting protruding cigarettes on a conveyor belt between a packaging machine and a cigarette machine includes a support 1, a cigarette rejection component 3, a cigarette photographing component 4, and an industrial control computer. One end of the support 1 is connected to one side wall of a cigarette conveyor 2. The inlet end of the cigarette conveyor 2 is connected to the outlet end of the cigarette machine, and the outlet end of the cigarette conveyor 2 is connected to the inlet end of the packaging machine. The cigarette rejection component 3 is adjustablely connected to the support 1. The blowing end of the cigarette rejection component 3 faces the conveying area of ​​the cigarette conveyor 2. The cigarette photographing component 4 is located diagonally above the cigarette rejection component 3 and is close to the direction from which the cigarettes are being conveyed by the cigarette conveyor 2. The cigarette photographing component 4 is adjustablely connected to the support 1, and the photographing end of the cigarette photographing component 4 is located above the conveying area of ​​the cigarette conveyor 2. The industrial control computer is electrically connected to the cigarette photographing component 4 and is used to identify cigarettes with incorrect orientation in the photograph taken by the cigarette photographing component 4. The industrial control computer is electrically connected to the cigarette rejection component 3 through a PLC controller.

[0041] In practical applications, when detecting and removing protruding cigarettes on the surface of the cigarette layer inside the cigarette conveyor 2, the cigarette conveyor 2 transports the layered cigarettes to the cigarette photographing unit 4. The cigarette photographing unit 4 then takes a picture of the cigarette layer, and the picture is transmitted to the router on the industrial control computer via a communication line connected to the cigarette photographing unit 4. The router and the industrial control computer then view each picture of the cigarette layer taken by the cigarette photographing unit 4 in real time using their built-in software. The detection frame on the software simultaneously detects whether there are protruding cigarettes on the surface of the cigarette layer. If a protruding cigarette is detected, the industrial control computer controls the cigarette rejection unit 3 to remain inactive via the PLC controller. If a protruding cigarette is detected, the industrial control computer controls the cigarette rejection unit 3 to blow the protruding cigarette out of the cigarette layer surface via the PLC controller. In this way, cigarettes on the surface of the cigarette layer can be removed in a timely manner, solving the problem of not being able to detect and remove protruding cigarettes on the surface of the cigarette layer in a timely manner.

[0042] It should be noted that the industrial control computer is based on existing technology of the tobacco factory, and its built-in software and detection frame are not improved or redesigned. Therefore, its structure will not be described in detail.

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 To facilitate the detection of the cigarette layer conveyed in the cigarette conveyor 2, a protruding cigarette detection device on the conveyor channel between the packaging machine and the cigarette machine also includes a cigarette arrival detection component 5. The cigarette arrival detection component 5 is located upstream of the cigarette photographing component 4 and is connected to the cigarette photographing component 4. The detection end of the cigarette arrival detection component 5 is located above the conveying area of ​​the cigarette conveyor 2, and the cigarette arrival detection component 5 is electrically connected to the cigarette photographing component 4 through a PLC controller.

[0044] In practical application, when the cigarette layer conveyed in the cigarette conveyor 2 is detected by the cigarette arrival detection component 5, the cigarette arrival detection component 5 will control the cigarette photographing component 4 to take a picture of the cigarette layer in the cigarette conveyor 2 through the PLC controller.

[0045] Please see Figure 1 and Figure 2 The cigarette arrival detection component 5, used to detect the cigarette layer conveyed by the cigarette conveyor 2, includes an adjustment head 6, a proximity switch 7, and a guide rod 8. The adjustment head 6 is used to adjustably connect to the guide rod 8 so that the adjustment head 6 can slide and adjust along the guide rod 8. The adjustment head 6 also serves as the base for mounting the proximity switch 7. The proximity switch 7 is used to detect whether the cigarette layer in the cigarette conveyor 3 has been conveyed to the correct position. The guide rod 8 is used for axial sliding adjustment of the adjustment head 6.

[0046] Specifically, the detection end of the proximity switch 7 is located above the conveying area of ​​the cigarette conveyor 2. The proximity switch 7 is electrically connected to the cigarette photographing device 4 through the PLC controller. The top of the proximity switch 7 is connected to the bottom of the adjusting head 6. The adjusting head 6 is tunably connected to one end of the guide rod 8. The other end of the guide rod 8 is connected to the cigarette photographing device 4.

[0047] In practical applications, before the cigarette conveyor 2 conveys the cigarette layer, the adjusting head 6 can be adjusted to the corresponding position along the guide rod 8 and locked according to the required adjustment distance between the proximity switch 7 and the industrial camera 9. At the same time, the industrial camera 9 is also indirectly moved to the corresponding position and locked. In this way, the distance between the cigarette photographing device 4 and the proximity switch 7 is adjusted to the corresponding distance. After the above adjustments are completed, when the cigarette layer in the cigarette conveyor 2 is conveyed to the proximity switch 7 and detected by the proximity switch 7, the proximity switch 7 will control the cigarette photographing device 4 through the PLC controller to take a picture of the surface of the cigarette layer in the cigarette conveyor 2.

[0048] Please see Figure 3 and Figure 4The cigarette photographing device 4, used to photograph the surface of the cigarette layer inside the cigarette conveyor 2, includes an industrial camera 9, an adjustment head 2 10, a guide rod 2 11, and an adjustment head 3 12. The industrial camera 9 is used to photograph the cigarette layer conveyed on the cigarette conveyor 2. The adjustment head 2 10 is connected to the industrial camera 9 on one hand and is also adjustablely connected to the guide rod 2 11 on the other hand, so that the adjustment head 2 10 is adjustable along the axial direction of the guide rod 2 11. The adjustment head 3 12 is connected to the guide rod 2 11 on one hand and is also adjustablely connected to the guide rod 3 13 on the other hand, so that the adjustment head 12 is adjustable in the vertical direction.

[0049] Specifically, the other end of guide rod 18 is connected to one side wall of adjustment head 2 10, the bottom of adjustment head 2 10 is connected to the top of industrial camera 9, adjustment head 2 10 is tunably connected to one end of guide rod 2 11, the other end of guide rod 2 11 is connected to one side wall of adjustment head 3 12, and adjustment head 3 12 is tunably connected to support member 1.

[0050] In practical applications, before the industrial camera 9 takes pictures of the cigarette layer inside the cigarette conveyor 2, the position of the adjusting head 2 10 on the guide rod 2 11 can be adjusted according to the distance between the industrial camera 9 and the proximity switch 7 and the conveying area of ​​the cigarette conveyor 2. This will move the industrial camera 9 and the proximity switch 7 to the corresponding position of the conveying area of ​​the cigarette conveyor 2. After the above adjustments are completed and the proximity switch 7 detects the cigarette layer being conveyed, the proximity switch 7 will control the industrial camera 9 through the PLC controller to take pictures of the cigarette layer inside the cigarette conveyor 2.

[0051] It should be noted that the industrial camera 9 is located downstream of the proximity switch 7, and the shooting end of the industrial camera 9 is located above the conveying area of ​​the cigarette conveyor 2. The industrial camera 9 is electrically connected to the industrial control machine. The industrial camera 9 and the proximity switch 7 are common equipment in cigarette factories. The industrial camera 9 and the proximity switch 7 are existing technologies, and no improvements or designs have been made to them. Therefore, their structures will not be described in detail.

[0052] Please see Figure 11 , Figure 4 , Figure 6 and Figure 7 The first adjusting head 6, which is slidably and adjustablely connected to the guide rod 8, and the second adjusting head 10, which is slidably and adjustablely connected to the guide rod 11, are both first adjusting heads with the same structure. The first adjusting head includes an adjusting head 32 and a locking bolt 33. The adjusting head 32 is provided with a sleeve through hole 34, which communicates with the groove 35 opened on the adjusting head 32. The internal threaded holes on the groove arms 36 on both sides of the groove 35 are connected by the locking bolt 33.

[0053] In practical applications, when adjusting the lateral distance between the industrial camera 9 and the proximity switch 7 and the cigarette conveyor 2, the adjusting head 10 can be adjusted to the corresponding position along the guide rod 11 and locked according to the required adjustment distance between the industrial camera 9 and the cigarette conveyor 2. At the same time, the industrial camera 9 and the proximity switch 7 are also indirectly moved to the required adjustment distance from the cigarette conveyor 2, thereby improving the practicality of the equipment.

[0054] It should be noted that one internal threaded hole on the groove arm 36 is completely penetrated, while the other internal threaded hole on the groove arm 36 is not completely penetrated.

[0055] Please see Figure 5 and Figure 6 The support member 1, which is adjustablely connected to the cigarette photographing device 4, includes a guide rod 3 13, a guide rod 4 14, an adjusting head 4 15, and a connecting plate 16; wherein, the guide rod 3 13 is used as a support rod for mounting the cigarette photographing device 4; the adjusting head 4 15 is used to connect to the guide rod 3 13 on one hand, and to be adjustablely connected to the guide rod 4 14 on the other hand; the connecting plate 16 is used to connect to the side wall of the cigarette conveyor 2.

[0056] Specifically, one end of the adjusting head 3 12 is adjustablely connected to the guide rod 3 13, the other end of the guide rod 3 13 is connected to one side wall of the adjusting head 4 15, one end of the adjusting head 4 15 is adjustablely connected to the guide rod 4 14, the other end of the guide rod 4 14 is connected to the side wall of the connecting plate 16, and the connecting plate 16 is connected to the channel 17 on the side wall of the cigarette conveyor 2.

[0057] In practical application, when mounting the cigarette photographing device 4 onto the support 1, first connect the connecting plate 16 to the channel 17 on the side wall of the cigarette conveyor 2, then connect one end of the guide rod 14 to the connecting plate 16, and the other end of the guide rod 14 to the adjusting head 15 in an adjustable manner. Then connect one end of the guide rod 13 to one side wall of the adjusting head 15. In this way, the support 1 is mounted on the cigarette conveyor 2. Then, the adjusting head 12 in the cigarette photographing device 4 is adjusted to one end of the guide rod 13 to complete the process of mounting the cigarette photographing device 4 onto the support 1.

[0058] Please see Figure 11 , Figure 4 , Figure 6 and Figure 7 The first adjusting head is of the same structure as the adjusting head four 15 that is slidably adjustable with the guide rod three 13. The first adjusting head includes an adjusting head 32 and a locking bolt 33. The adjusting head 32 is provided with a sleeve through hole 34, which communicates with the groove 35 opened on the adjusting head 32. The internal threaded holes on the groove arms 36 on both sides of the groove 35 are connected by the locking bolt 33.

[0059] In practical applications, when coarsely adjusting the position of the cigarette rejection component 3, industrial camera 9, and proximity switch 7 relative to the conveying area of ​​the cigarette conveyor 2, the position of the adjusting head 4 15 on the guide rod 4 14 can be adjusted according to the required adjustment position between the cigarette rejection component 3, industrial camera 9, and proximity switch 7 and the conveying area of ​​the cigarette conveyor 2. This indirectly adjusts the required adjustment position between the cigarette rejection component 3, industrial camera 9, and proximity switch 7 and the conveying area of ​​the cigarette conveyor 2, thereby improving the applicability of the equipment.

[0060] It should be noted that one internal threaded hole on the groove arm 36 is completely penetrated, while the other internal threaded hole on the groove arm 36 is not completely penetrated.

[0061] Please see Figure 5 , Figure 3 and Figure 10 A cigarette rejection component 3, used to remove protruding cigarettes from the surface of the cigarette layer inside the cigarette conveyor 2, is adjustablely connected to a guide rod 3 13 between an adjustment head 4 15 and an adjustment head 3 12. The cigarette rejection component 3 includes an adjustment head 5 18, a guide rod 5 19, a guide rod 6 20, a guide rod 7 21, an adjustment head 7 23, an adjustment head 6 28, and a valved nozzle 22. Among them, the adjustment head 5 18 is used to indirectly coarsely adjust the vertical distance between the nozzle 22 and the conveying area of ​​the cigarette conveyor 2; the adjustment head 7 23 is used to indirectly finely adjust the vertical distance between the nozzle 22 and the conveying area of ​​the cigarette conveyor 2; and the adjustment head 6 28 is used to indirectly adjust the corresponding position of the nozzle 22 and the notch on the cigarette conveyor 2.

[0062] Specifically, adjustment head 5 18 is located on guide rod 3 13 between adjustment head 4 15 and adjustment head 3 12. Adjustment head 5 18 is tunably connected to guide rod 3 13. One sidewall of adjustment head 5 18 is connected to one end of guide rod 5 19. The other end of guide rod 5 19 is tunably connected to adjustment head 6 28. One sidewall of adjustment head 6 28 is connected to one end of guide rod 6 20. The other end of guide rod 6 20 is tunably connected to adjustment head 7 23. One sidewall of adjustment head 7 23 is connected to one end of guide rod 7 21. Guide rod 7 21 is tunably connected to adjustment head 8 29. A valve-equipped nozzle 22 is inserted into the connecting plate 30 connected to one sidewall of adjustment head 8 29. The nozzle 22 is inclined, with its outlet facing the cigarette conveyor 2's conveying area.

[0063] The valve on the air nozzle 22 is electrically connected to the industrial control computer via a PLC controller, and the air nozzle 22 is connected to an air pump or an air compressor via an air pipe.

[0064] In practical application, before the air nozzle 22 blows air onto the protruding cigarettes on the surface of the cigarette layer inside the cigarette conveyor 2 to remove them, the position of the adjusting head 8 29 on the guide rod 7 21 can be adjusted according to the lateral distance between the air nozzle 22 and the conveying area inside the cigarette conveyor 22, so that the air nozzle 22 is moved to a position corresponding to the conveying area inside the cigarette conveyor 22. Then, according to the vertical distance between the air nozzle 22 and the conveying area inside the cigarette conveyor 22, the position of the adjusting head 5 18 along the guide rod 3 13 can be coarsely adjusted to move the air nozzle 22 to a rough position corresponding to the conveying area inside the cigarette conveyor 22. Finally, the adjusting head 7 18 can be finely adjusted. 23. At the position of guide rod six 20, move the air nozzle 22 to the position corresponding to the conveying area inside the cigarette conveyor 22. Then, according to the position of the air nozzle 22 and the corresponding notch 31 on the side wall of the conveying area of ​​the cigarette conveyor 2, adjust the position of the adjusting head eight on guide rod five 19 so that the position of the air nozzle 22 and the corresponding notch 31 on the side wall of the conveying area of ​​the cigarette conveyor 2 is adjusted. After the above adjustments are completed, the industrial control computer controls the valve on the air nozzle 22 to open through the PLC controller. The air discharged from the air nozzle 22 blows the protruding cigarettes on the surface of the cigarette layer inside the cigarette conveyor 22 away from the cigarette air conveyor 2.

[0065] It should be noted that industrial control computers, air pumps, and air compressors are common equipment in tobacco factories. These are existing technologies, and no improvements or designs have been made to them. Therefore, their structures will not be described in detail.

[0066] Please see Figure 11 , Figure 4 , Figure 6 and Figure 7 The adjusting head 18, which is adjustable along the guide rod 19, the adjusting head 28, the adjusting head 23, which is adjustable along the guide rod 20, and the adjusting head 29, which is adjustable along the guide rod 21, are all first adjusting heads of the same structure. The first adjusting head includes an adjusting head 32 and a locking bolt 33. The adjusting head 32 has a sleeve through hole 34, which communicates with the groove 35 on the adjusting head 32. The internal threaded through holes on the groove arms 36 on both sides of the groove 35 are connected by the locking bolt 33.

[0067] In practical applications, when adjusting the lateral straight-line distance between the air nozzle 22 and the cigarette conveyor 2 conveying area, the locking bolt 33 on the adjusting head 32 can be turned first to make the adjusting head 32 and the guide rod 7 21 in a movable state. Then, the adjusting head 32 is pushed axially along the guide rod 7 21 to a suitable position and stopped. Finally, the locking bolt 33 is turned to lock the adjusting head 32 and the guide rod 7 21 to a suitable position, thereby indirectly locking the air nozzle 22 at a suitable straight-line distance from the cigarette conveyor 2 conveying area, thus improving the applicability of the equipment.

[0068] When coarsely adjusting the vertical straight-line distance between the air nozzle 22 and the cigarette conveyor 2 conveying area, the required adjustment distance between the air nozzle 22 and the cigarette conveyor 2 conveying area can be determined by first turning the locking bolt 33 on the adjusting head 32 to make the adjusting head 32 and the guide rod 313 in a movable state, then pushing the adjusting head 32 along the axial direction of the guide rod 313 to a suitable position and stopping, and finally turning the locking bolt 33 to lock the adjusting head 32 and the guide rod 313 to a suitable position, thereby indirectly locking the air nozzle 22 at a suitable straight-line distance from the cigarette conveyor 2 conveying area, thus improving the applicability of the equipment.

[0069] When fine-tuning the vertical straight-line distance between the air nozzle 22 and the cigarette conveyor 2 conveying area, the required adjustment distance between the air nozzle 22 and the cigarette conveyor 2 conveying area can be achieved by first turning the locking bolt 33 on the adjusting head 32 to make the adjusting head 32 and the guide rod 6 20 in a movable state, then pushing the adjusting head 32 along the axial direction of the guide rod 6 20 to a suitable position and stopping, and finally turning the locking bolt 33 to lock the adjusting head 32 and the guide rod 6 20 to a suitable position, thereby indirectly locking the air nozzle 22 at a suitable straight-line distance from the cigarette conveyor 2 conveying area, thus improving the applicability of the equipment.

[0070] When adjusting the air nozzle 22 to the position corresponding to the notch 31 on the side wall of the cigarette conveyor 2, first tighten the locking bolt 33 on the adjusting head 32 to make the adjusting head 32 and the guide rod 19 in a movable state. Then push the adjusting head 32 along the axial direction of the guide rod 19 to the appropriate position and stop. Finally, tighten the locking bolt 33 to lock the adjusting head 32 and the guide rod 19 to the appropriate position, thereby indirectly locking the air nozzle 22 to the position corresponding to the notch 31 on the side wall of the cigarette conveyor 2. This allows the air nozzle 22 to remove the cigarette from the notch 31 of the cigarette conveyor 2, thus improving the applicability of the equipment.

[0071] It should be noted that one internal threaded hole on the groove arm 36 is completely penetrated, while the other internal threaded hole on the groove arm 36 is not completely penetrated.

[0072] Please see Figure 8 To facilitate the collection of cigarettes rejected by the nozzle 22, a protruding cigarette detection device on the conveyor between the packaging machine and the cigarette machine also includes a cigarette rejection and collection component 24. The cigarette rejection and collection component 24 is configured to collect cigarettes blown by the nozzle 22. The nozzle 22 and the cigarette rejection and collection component 24 are arranged in a corresponding manner. The cigarette rejection and collection component 24 is set on the other side wall of the cigarette conveyor 2, and the feeding end of the cigarette rejection and collection component 24 is connected to the notch 31 on the other side wall of the cigarette conveyor 2.

[0073] In practical application, when the air nozzle 22 blows the protruding cigarettes on the surface of the cigarette layer inside the cigarette conveyor 2 to the collection box, the cigarettes blown by the air nozzle 22 will first roll along the surface of the cigarette layer inside the conveyor 2 to the notch 31 on the cigarette conveyor 2, and then enter the cigarette rejection and collection component 24 through the notch 31 on the cigarette conveyor 2 and the feeding end of the cigarette rejection and collection component 24, so that they can be recycled by workers later.

[0074] It should be noted that the cigarette conveyor 2 is existing equipment in the cigarette factory, and the technology used is current; no improvements or designs have been made to it, therefore its structure will not be described in detail. The cigarette conveyor 2 can be a belt conveyor.

[0075] Please see Figure 8 and Figure 9 The cigarette rejection and storage component 24, used for storing rejected cigarettes, includes a storage box 25, a detection grating 26, and an audible and visual alarm 27. The storage box 25 is used to hold cigarettes rejected from the cigarette conveyor 2. The detection grating 26 is used to detect whether rejected cigarettes have entered the storage box 25. The audible and visual alarm 27 is used to remind staff that rejected cigarettes have not entered the storage box 25.

[0076] Specifically, the storage box 25 is a rectangular cavity structure with one side wall and the top open. The open end of the side wall of the storage box 25 is connected to the notch 31 on the side wall of the cigarette conveyor 2. A detection grating 26 is provided on the inner side wall of the storage box 25 near the feeding end of the storage box 25 (the detection grating 26 is provided on the inner side wall of the storage box 25 near the open end of the top of the storage box 25). The detection grating 26 is electrically connected to the audible and visual alarm 27 through the PLC controller. The audible and visual alarm 27 is set at or installed at the bottom of the cigarette conveyor 2.

[0077] In practical application, during the process of the nozzle 22 blowing the protruding cigarettes on the surface of the cigarette layer inside the cigarette conveyor 2 into the storage box, since a detection grating 26 is installed on the inner side wall of the storage box 25, if the rejected cigarettes do not fall into the storage box 25, the detection grating 26 will control the audible and visual alarm 27 through the PLC controller to remind the staff that the cigarettes have not been rejected from the cigarette conveyor 2 or that the rejected cigarettes have not fallen into the storage box 15 smoothly; if the rejected cigarettes fall into the storage box 25, the detection grating 16 will not control the audible and visual alarm 27 through the controller.

[0078] It should be noted that (1) the detection grating 26 and the audible and visual alarm 27 are commonly used equipment in tobacco factories. The detection grating 26 and the audible and visual alarm 27 are existing technologies, and no improvements or designs have been made to them. Therefore, their structures are not described in detail.

[0079] (2) To prevent the nozzle 22 from blowing the cigarette across the storage box 25, a protruding baffle is provided or connected to the top of the side wall of the storage box 25 away from the cigarette conveyor 2. When the cigarette is blown to the protruding baffle, it will fall into the storage box due to the resistance of the baffle. The side wall of the baffle is provided with several through holes at intervals so that the air blown by the nozzle 22 can be discharged through the through holes.

[0080] (3) The lowest point of the opening on the side wall of the cigarette conveyor 2 is flush with the top of the cigarette layer inside the cigarette conveyor 2. This means that when the nozzle 22 blows air onto the surface of the cigarette layer, the cigarettes in the neatly arranged cigarette layer inside the cigarette conveyor 2 will not be blown into the storage box 25, but only the cigarettes protruding from the surface of the cigarette layer will be blown into the storage box 25. The cigarette layer consists of cigarettes stacked sequentially from the bottom to the top inside the cigarette conveyor.

[0081] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
