[0002] In the prior art, various treatments need to be performed on cigarette rods and the treatment effects need to be detected. For example, a cigarette rod online laser drilling device is used to complete the drilling of a part of the filter tip of a filter-tipped cigarette rod to accurately control the ventilation rate of the cigarette rod filter tip. During production, due to reasons such as the soiling of the lens and cigarette rod on the laser optical path, or the fouling of the laser drum and the cigarette rod pusher wheel, problems such as aperture deviation or fewer holes occur in laser drilling, resulting in the exceeding of the filter tip ventilation rate data and causing fluctuations in the suction taste. Therefore, it is necessary to detect the drilling effect. The inventor designed a cigarette rod detection device to clamp and detect cigarette rods. The bearing seat in the prior art is only used to simply install the bearing and support the rotating shaft, and its function is relatively single. In the cigarette rod detection device designed by the inventor, the used bearing seat assembly has more functions, enabling the cigarette rod detection device to better exert the cigarette rod detection effect.

[0073] As shown in the figure, the bearing seat assembly of the cigarette rod detection device of this embodiment includes a bearing seat and a bearing disposed within the bearing seat. The bearing is used to mount the drive cylinder within the bearing seat. An installation hole is further provided on the bearing seat, and a position detection sensor installed within the installation hole is used to detect the position of the push rod within the drive cylinder.

[0074] As shown in the figure, the cigarette rod detection device of this embodiment includes a drive cylinder 3, a drive assembly, a push assembly, a clamping assembly, a fitting 2, and a fixing member 17.

[0075] The drive cylinder 3 includes a first cylinder body 31, a cylinder cavity 32 disposed within the first cylinder body 31, a first transmission portion 33 disposed on the first cylinder body 31, and a first connection portion 34 disposed at one end of the first cylinder body 31.

[0076] The drive assembly is drivingly connected to the drive cylinder 3 and is used to drive the drive cylinder 3 to rotate. In the embodiment shown in the figure, the drive assembly includes a motor 11, a first transmission wheel 12, a second transmission wheel 14, and a belt connecting the first transmission wheel 12 and the second transmission wheel 14. The motor is installed on the mounting seat 7. The motor drives the first transmission wheel 12 to rotate. The belt transmits power to the second transmission wheel 14, and the second transmission wheel 14 drives the drive cylinder 3 to rotate. In the embodiment shown in the figure, a keyway is provided on the drive cylinder, and a transmission key that mates with the keyway on the drive cylinder 3 is provided on the second transmission wheel. The second transmission wheel drives the drive cylinder to rotate through the cooperation of the transmission key and the keyway.

[0077] The pushing component includes a second transmission part, a pushing rod 6 disposed in the cylinder cavity 32, a third transmission part 63 disposed on the pushing rod 6, and a first thread part 61 disposed on the pushing rod 6, the axis of the thread being parallel to the axis of the transmission cylinder. The first transmission part 33 and the second transmission part are slidably engaged along the axis direction of the transmission cylinder, and when the transmission cylinder 3 rotates, the pushing rod 6 is driven to rotate coaxially with the transmission cylinder 3 through the cooperation of the first transmission part 33 and the second transmission part. Torque can be transmitted between the first transmission part 33 and the second transmission part and they can slide relative to each other. In some embodiments, one of the first transmission part and the second transmission part includes a chute, and the other includes a sliding block that cooperates with the chute. In the embodiment shown in the figure, the first transmission part includes a chute extending axially along the first cylinder body 31, the second transmission part includes an annular ring 91, a sliding column 92 fixedly connected to the annular ring 91, and a connection hole fixedly connected to the sliding column 92 and disposed on the pushing rod 6. In the embodiment shown in the figure, it includes a plurality of sliding columns 92 distributed circumferentially along the pushing rod and a plurality of connection holes distributed circumferentially on the pushing rod. One connection hole is fixedly connected to one sliding column 92 by means of threaded connection or the like. During operation, the transmission cylinder transmits torque to the sliding column through the chute, and the sliding column transmits the torque to the connection hole on the pushing rod to rotate the pushing rod. At the same time, the sliding column can also move axially relative to the chute along the axis of the transmission cylinder.

[0078] The clamping assembly includes a clamping seat 4 and a clamping member 5 mounted on the clamping seat 4. The clamping seat 4 includes a second connecting portion 41 detachably connected to the first connecting portion 34 and a fourth transmission portion 42 provided on the clamping seat 4. The third transmission portion 63 and the fourth transmission portion 42 are slidably engaged along the axial direction of the transmission cylinder. When the push rod 6 rotates, the clamping seat 4 is driven to rotate coaxially with the push rod 6 through the cooperation of the third transmission portion 63 and the fourth transmission portion 42. The cooperation between the third transmission portion 63 and the fourth transmission portion 42 is similar to the cooperation between the first transmission portion and the second transmission portion. One of them includes a chute, and the other includes a sliding block that cooperates with the chute. In the illustrated embodiment, the third transmission portion includes a chute provided on the push rod, and the fourth transmission portion 42 includes a transmission hole provided on the clamping seat 4 and a transmission pin inserted into the transmission hole and into the chute of the fourth transmission portion. The transmission pin can slidably cooperate with the chute of the fourth transmission portion. The fourth transmission portion transmits the torque to the transmission hole through the cooperation of the chute and the transmission pin, and then drives the clamping seat 4 to rotate. In this embodiment, the clamping seat 45 is detachably connected to the first connecting portion 34 through the second connecting portion 41, which can realize the convenient installation of the clamping seat 45 on the transmission cylinder and the convenient installation or separation of the clamping member from the clamping seat 45 after the clamping seat 45 is disassembled. After the clamping seat is installed on the transmission cylinder, since the push rod can reliably transmit the torque to the clamping seat 45, there is no need for the connection between the clamping seat 45 and the transmission cylinder to have the requirement of reliably transmitting the torque. Therefore, the detachable connection between the clamping seat 45 and the transmission cylinder can be set as a simple threaded connection, for example, which reduces the connection requirement and enables the convenient and simple disassembly between the clamping seat 45 and the transmission cylinder.

[0079] The clamping member 5 has a state of loading cigarettes in which the clamping cavity opens to load cigarettes and a state of clamping cigarettes in which the clamping cavity shrinks to clamp cigarettes. The clamping member 5 is used to be mounted on the clamping seat and to clamp cigarettes. The clamping member 5 has a clamping cavity for clamping cigarettes. In the illustrated embodiment, the clamping member 5 includes a plurality of clamping blocks, and the plurality of clamping blocks surround to form a clamping cavity for clamping cigarettes. The push rod 6 drives the clamping member 5 to switch between the state of loading cigarettes and the state of clamping cigarettes by moving in the positive direction and the reverse direction along the axial direction of the transmission cylinder 3. If the movement of the push rod 6 in one direction along its axial direction is the positive direction movement, then the movement in the opposite direction along its axial direction is the reverse direction movement opposite to the positive direction. In the illustrated embodiment, the movement of the push rod towards the direction of the clamped cigarette is the positive direction movement, and the movement away from the cigarette is the reverse direction movement. When the push rod moves in the positive direction, it drives the clamping cavity of the clamping member 5 to open, so that cigarettes can be loaded or taken out. When the push rod moves in the reverse direction, it can drive the clamping cavity of the clamping member 5 to become smaller, so that the loaded cigarettes can be clamped.

[0080] The fitting 2 is rotatably arranged in the cylinder cavity 32 relative to the transmission cylinder 3 and includes a second thread portion 21 that is in threaded engagement with the first thread portion 61. The fixing member 17 is used to cooperate with the fitting 2. The fixing member 17 has a first state that restricts the fitting 2 from rotating about the axis of the thread of the first thread portion 61 and a second state that enables the fitting 2 to rotate about the axis of the thread of the first thread portion 61. In the illustrated embodiment, the fixing member includes an electromagnetic clutch 17. The electromagnetic clutch includes a first part and a second part that are relatively rotatable. The first part is mounted on the mounting seat 7 through the mounting bracket 16 and the mounting block 15. The second part is fixedly connected to the fitting 2. By connecting and separating the first part and the second part, the fixing member 17 can be switched between the first state and the second state.

[0081] When the fixing member 17 is switched to the first state and the fitting 2 is restricted from rotating, when the push rod 6 is driven to rotate by the transmission cylinder, the push rod can produce a motion effect similar to that of a screw-nut mechanism through the threaded engagement between the first thread portion 61 and the second thread portion of the fitting 2, causing the push rod to move along its axial direction. When the drive assembly drives the transmission cylinder to rotate in different directions, the drive cylinder also drives the push rod to rotate in different directions. Then, the push rod will move in the positive or negative direction under the action of the second thread portion of the fitting 2 that is restricted from rotating, so as to be able to drive the clamping member to switch between the state of loading cigarettes and the state of clamping cigarettes. When the fixing member 17 is switched to the second state, the fitting 2 is not restricted from rotating. The fitting 2 can rotate about the axis of the thread of the first thread portion 61, that is, it can rotate relative to the transmission cylinder. Thus, when the push rod 6 is driven to rotate by the transmission cylinder, the fitting 2 can rotate following the push rod, the push rod does not move, and the push rod drives the clamping seat, the clamping member, and the cigarette to rotate, so that the outer peripheral surface of the cigarette can be comprehensively detected by the detection component of the cigarette detection device, such as the camera detection device 18 shown in the figure.

[0082] In the illustrated embodiment, the bearing includes a first bearing 93 and a second bearing 94. The bearing seat is provided with a first bearing cavity 831 and a second bearing cavity 832. The first bearing 93 and the second bearing 94 are respectively installed in the first bearing cavity 831 and the second bearing cavity 832. Both ends of the transmission cylinder 3 are installed on the bearing seat through the first bearing 93 and the second bearing 94. The cigarette detection device further includes a controller. The bearing seat is also provided with a position detection sensor that is signal-connected to the controller. The position detection sensor is used to detect the position of the push rod 6. By providing the position detection sensor in the bearing seat assembly of this embodiment, the position of the push rod 6 along the axial direction of the transmission cylinder can be detected, so as to judge whether the push rod plays a pushing role on the clamping member at this time, judge the state of the clamping member, and also adjust the size of the clamping cavity of the clamping member and control the magnitude of the clamping force for clamping the cigarette by detecting and controlling the position of the push rod 6 along the axial direction in some embodiments.

[0083] For the bearing seat assembly of the cigarette rod detection device in this embodiment, by designing the mounting holes and installing the position detection device in the mounting holes, in addition to being able to bear the load of shaft parts, it can also detect the positions of the parts related to the shaft parts being carried. It has diverse functions, high integration, and a compact structure.

[0084] For the cigarette rod detection device in this embodiment, by switching the fixing member 17 between the first state and the second state, and by driving the transmission cylinder to rotate in different directions, the clamping member 5 can be switched between the cigarette loading state and the cigarette clamping state. Thus, the operations of loading the cigarette rod 100 and clamping the cigarette rod 100 can be conveniently carried out, and after the cigarette rod is clamped, it can be automatically rotated so that different parts of the cigarette rod can be conveniently detected by the detection components. At the same time, the clamping seat 4 can be conveniently detachably connected to the transmission cylinder 3, so that the installation and disassembly of the clamping member 5 can be facilitated. After the clamping seat 4 is connected to the transmission cylinder 3, the clamping seat 4 can reliably drive the clamping member 5 and the cigarette rod to rotate coaxially with the transmission cylinder 3. The cigarette rod clamping assembly applying the bearing seat assembly

[0085] In some embodiments, the mounting holes are provided on the radial outer side of the bearing, and the position detection sensors include a first position detection sensor and a second position detection sensor arranged along the axial direction of the bearing in the mounting holes. Since the mounting holes are provided on the radial outer side of the bearing, the arrangement of the position detection sensors can be more flexible, and the detection of the position detection sensors is less affected by the interference of the bearing and shaft parts such as the transmission cylinder carried by the bearing, and the detection is more accurate. By providing the first position detection sensor and the second position detection sensor arranged along the axial direction of the bearing, the positions of the parts to be detected along the axial direction of the bearing can be detected. The detection can be directly carried out, or by setting a detection part fixedly connected to the parts to be detected to reflect the positions of the parts to be detected, so as to realize the flexible detection of the parts.

[0086] In some embodiments, as shown in the figure, the bearing includes a first bearing 93 and a second bearing 94. The bearing seat is provided with a first bearing cavity 831 and a second bearing cavity 832. The first bearing 93 and the second bearing 94 are respectively installed in the first bearing cavity 831 and the second bearing cavity 832, and the mounting holes are provided between the first bearing cavity 831 and the second bearing cavity 832. The setting of the mounting holes in this embodiment enables the mounting holes to have more space for setting, and also enables the position detection device to have a larger space for detecting the positions of the parts.

[0087] In some embodiments, the cigarette detection device further includes a limiting component for restricting the movement of the fitting 2 relative to the transmission cylinder along the axial direction of the transmission cylinder 3. In the embodiment shown in the figure, the limiting component includes a first annular groove 22 with a U-shaped cross-section of the groove body provided on the fitting 2, an annular retaining ring 23 installed on the first annular groove 22, and a second annular groove 35 with a U-shaped cross-section of the groove body provided at one end of the transmission cylinder 3. The annular retaining ring 23 is inserted into the groove body of the second annular groove 35 at the same time. The second annular groove 35 is jointly formed by the end groove 351 of the transmission cylinder 3 and the gasket 352 installed at the end of the transmission cylinder 3. When the cigarette to be clamped rotates so that all parts of its outer peripheral surface are comprehensively detected by the detection component, the fixing member 17 switches to the second state, the fitting 2 is not restricted from rotating, the fitting 2 can rotate relative to the transmission cylinder, the push rod 6 is driven to rotate by the transmission cylinder, and the fitting 2 rotates following the push rod. If the fitting is not restricted from moving by the limiting component, the fitting 2 and the push rod may move axially, which may affect the clamping member. For example, it may cause the clamping member to switch to the state of loading cigarettes, resulting in loose cigarettes. In this embodiment, the limiting component is provided to restrict the movement of the fitting 2 relative to the transmission cylinder along the axial direction of the transmission cylinder 3, which can restrict the axial movement of the fitting and the push rod when the cigarette is rotated and detected, and avoid interference of the push rod and the fitting on the clamping member.

[0088] In some embodiments, the first connecting portion 34 and the second connecting portion 41 are detachably connected by screw fit.

[0089] In some embodiments, as shown in the figure, the clamping seat 4 includes a plurality of guiding holes 43 extending radially. The clamping member 5 includes a plurality of clamping blocks 51. The clamping block 51 includes a moving portion 511 extending into the clamping seat 4 and mating with the guiding holes 43 one by one, and a clamping portion extending out of the clamping seat 4 for clamping a cigarette. The guiding holes 43 extend along the radial direction of the clamping seat 4. In the embodiment shown in the figure, the guiding holes 43 penetrate the clamping seat 4 radially. In some embodiments not shown in the figure, the guiding holes 43 may not penetrate the clamping seat 4 and only extend along the radial direction of the clamping seat 4 to the middle of the wall of the clamping seat 4 and then stop extending. The moving portion 511 of each clamping block 51 mates with one guiding hole 43 and can move relative to the guiding hole 43 along the radial direction of the clamping seat. When the push rod 6 moves in the direction close to the clamping portion, it simultaneously pushes the moving portions 511 of the plurality of clamping blocks 51 to move along the guiding holes 43 that the moving portions 511 mate with in the radial outer direction of the clamping seat 4 so that the clamping member 5 switches to the cigarette loading state. The clamping assembly further includes an elastic member mating with the moving portions 511 of the plurality of clamping blocks 51. The elastic force of the elastic member causes the moving portions 511 of the plurality of clamping blocks 51 to tend to move in the radial inner direction of the clamping seat 4. The elastic member includes, for example, an elastic ring. In the embodiment where the guiding hole 43 penetrates the clamping seat 4 radially as shown in the figure, a first installation groove 513 is further provided on the moving portion of the clamping block. A circular second installation groove 44 is provided on the clamping seat. After the clamping block is installed on the clamping seat, the circular elastic ring is installed on the second installation groove and at the same time installed on the first installation groove 513, and the elastic force of this elastic ring seems to point to the radial inner side of the elastic ring. After a cigarette is loaded into the clamping cavity, after the push rod leaves the clamping block, the elastic force of the elastic ring causes the clamping block to move in the radial inner direction of the clamping seat, so that the clamping block clamps the cigarette. When the push rod moves in the direction close to the clamping block, the push rod pushes the clamping block to overcome the elastic force of the elastic ring, so that the clamping block moves in the radial outer direction of the clamping seat, and the clamping member switches to the cigarette loading state.

[0090] In some embodiments, the clamping seat 4 includes a second cylinder 451 and an annular disc 452 located at the end face of the cylinder. The guiding hole 43 includes a strip-shaped through hole provided on the second cylinder 451, that is, a strip-shaped through hole penetrating the second cylinder 451 along the radial direction of the clamping seat. The moving portion 511 is inserted into the strip-shaped through hole, and the protruding portion 512 protrudes from the through hole in the middle of the annular disc out of the clamping seat 4. The moving portion 511 and the protruding portion 512 are connected by a stepped surface. In the embodiment shown in the figure, the stepped surface extends into the guiding hole 43. The guiding hole 43 guides the movement of the moving portion in the guiding hole through contact with the stepped surface, so that the clamping seat can stably switch between the cigarette loading state and the cigarette clamping state.

[0091] In some embodiments, as shown in the figure, at least one of the surface of the push rod 6 that cooperates with the moving part 511 and the surface of the moving part 511 that cooperates with the push rod is a wedge-shaped surface. In the embodiment shown in the figure, both the surface of the push rod 6 and the surface of the moving part 511 are wedge-shaped surfaces at the mating position. As shown in the figure, the end of the push rod is a tapered part, and the outer surface of the tapered part is an inclined surface. The movement of the push rod can reliably push the moving part 511 to move radially along the clamping seat through the action of the wedge-shaped surface.

[0092] In some embodiments, the first transmission part 33 includes a strip-shaped hole provided on the first cylinder 31. The second transmission part includes an annular ring 91 arranged around the transmission cylinder 3 and a sliding column 92 that is slidably matched with the strip-shaped hole and fixedly connected to the push rod 6 and the annular ring. The position detection sensor is used to detect the position of the annular ring 91. In the embodiment shown in the figure, the sliding column 92 is provided with a screw hole, and the annular ring is provided with a countersunk hole. The annular ring and the sliding column 92 can be connected by screwing a screw through the countersunk hole of the annular ring and the screw hole of the sliding column 92. Since the annular ring 91 is fixedly connected to the push rod through a sliding block, detecting the axial position of the annular ring can reflect the axial position of the push rod.

[0093] In some embodiments, the bearing seat includes a mounting hole 82 located radially outside the annular ring 91. The position detection sensor includes a first photoelectric detection switch 811 and a second photoelectric detection switch 812 provided in the mounting hole 82. Along the axis direction of the transmission cylinder 3, the annular ring 91 is located between the first photoelectric detection switch 811 and the second photoelectric detection switch 812. The first photoelectric detection switch 811 and the second photoelectric detection switch 812 can be axially arranged at corresponding positions of the axial limit position of the push rod. When the push rod moves in the positive or negative axial direction and is detected by the first photoelectric detection switch 811 or the second photoelectric detection switch 812, it means that the push rod has reached the restricted movement position along the axis. Thus, the controller can stop the rotation of the transmission cylinder and make the push rod stop moving. The positions of the first photoelectric detection switch 811 and the second photoelectric detection switch 812 along the axis of the transmission cylinder can be adjusted, so that the restricted movement position of the push rod along the axis can be adjusted.

[0094] In some embodiments, as shown in the figure, the cigarette detection device further includes a dust-proof sleeve 95. The dust-proof sleeve is threadedly engaged with the bearing seat and surrounds the clamping assembly. The dust-proof sleeve 95 surrounds the clamping assembly, which can play a role in protecting the cigarette detection device from dust entering, and helps to ensure the long-term reliable operation of the cigarette detection device.

[0095] In some embodiments, the controller described above may be a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any suitable combination thereof for performing the functions described in the present invention.
