Technical Field

[0001] The present invention relates to the technical field of cigarette appearance detection, and particularly relates to a cigarette appearance detection device. Background Art

[0002] Defects in the appearance of cigarettes not only affect the appearance of cigarettes, but even affect the sensory quality, reduce consumers' support for the brand, affect the economic benefits and brand image of the enterprise, and are not conducive to the long-term and healthy development of the brand. Therefore, it is necessary to detect the appearance of cigarettes to strengthen the control of cigarette appearance defects.

[0003] Currently, sampling inspection is mainly carried out through comprehensive cigarette detection devices such as comprehensive test benches. In Chinese Patent Application CN111972703A, a modular cigarette appearance detection device is disclosed. It places cigarettes vertically, uses a chuck assembly to hold the cigarettes, and then obtains images of the held cigarettes through an imaging device to achieve cigarette detection. However, this device has the following problems:

[0004] (1) The vertical falling distance of the cigarette is too far, and there is a lack of a cigarette guiding channel, making it difficult for the cigarette to accurately fall into the detection point;

[0005] (2) The method of clamping with two clamping pieces is likely to damage the cigarette;

[0006] (3) It cannot classify unqualified products and qualified products. Summary of the Invention

[0007] The present invention provides a cigarette appearance detection device, which uses a cigarette separating mechanism to convey cigarettes, and then uses an openable and closable cigarette clamping mechanism to hold and drive the cigarette to rotate, so that the imaging mechanism can obtain a complete circumferential image of the cigarette held by the cigarette clamping mechanism, and can realize the automatic conveying, clamping, detection and sorting of cigarettes, effectively reducing the manual intensity.

[0008] Specifically, the present invention is implemented as follows:

[0009] A cigarette appearance detection device includes:

[0010] A magazine for holding cigarettes;

[0011] A cigarette separating mechanism disposed below the magazine and communicating with the magazine, for separating the cigarettes from the magazine into single cigarettes and then conveying them downward;

[0012] A cigarette clamping mechanism disposed below the outlet of the cigarette separating mechanism, for clamping the cigarettes from the cigarette separating mechanism and driving the cigarettes to rotate;

[0013] An imaging mechanism disposed on one side of the cigarette clamping mechanism, for obtaining a circumferential image of the cigarette held by the cigarette clamping mechanism;

[0014] A recycling mechanism, which is arranged below the cigarette clamping mechanism and is used for recycling the cigarettes that have been detected;

[0015] The cigarette clamping mechanism includes:

[0016] A clamping component, configured as an openable and closable structure. When closed, it clamps the filter tip of the cigarette. When opened, it releases the filter tip of the cigarette;

[0017] A cigarette receiving groove, which is located in the middle of the clamping component, and the cigarette receiving groove is configured to rotate around its axis;

[0018] The clamping component includes: a plurality of clamping members. Each clamping member is configured as a rotating structure. When clamping the filter tip of the cigarette, the clamping member drives the cigarette to rotate, so as to enable the imaging mechanism to obtain a complete circumferential image of the cigarette.

[0019] Further, the cigarette clamping mechanism further includes:

[0020] A clamping driving member, which is in transmission connection with the clamping member and is used to drive the clamping member to open and close;

[0021] A clamping member rotation driving member, which is in transmission connection with the clamping member and is used to drive the clamping member to rotate;

[0022] A cigarette receiving groove rotation driving member, which is connected to the cigarette receiving groove and is used to drive the cigarette receiving groove to rotate.

[0023] Further, there are three clamping members, and they are distributed in a "pin" shape.

[0024] Further, the three clamping members are installed on a mounting disc. There are three arc-shaped grooves on the mounting disc, and the three clamping members are respectively slidably connected in the three arc-shaped grooves; the clamping driving member is in transmission connection with the mounting disc and is used to drive the mounting disc to rotate;

[0025] A fixed disc is provided on one side of the mounting disc close to the cigarette receiving groove. There are three waist-shaped grooves on the fixed disc, and the three clamping members respectively pass through the three waist-shaped grooves and extend towards the cigarette receiving groove; when the mounting disc rotates, it drives the clamping members to slide along the arc-shaped grooves and the waist-shaped grooves.

[0026] Further, an external gear and a mounting disc bearing are sleeved on the mounting disc. The clamping driving member is connected to the external gear, the mounting disc is fixedly connected to the external gear, and the clamping driving member is used to drive the mounting disc to rotate in the mounting disc bearing;

[0027] A sub-gear is provided at one end of the clamping member far from the cigarette receiving groove. The clamping member rotation driving member is located at the central position of the three clamping members, and a main gear is provided thereon. When the three clamping members are closed, the main gear meshes with the three sub-gears respectively.

[0028] Furthermore, the recycling mechanism comprises a qualified cigarette receiving box and a defective cigarette receiving box, and the qualified cigarette receiving box and the defective cigarette receiving box are respectively located on both sides of the cigarette receiving slot;

[0029] The cigarette receiving trough rotating drive member is located on the opposite side of the clamping member rotating drive member. When the imaging mechanism detects a qualified cigarette, the cigarette receiving trough rotates toward the qualified cigarette receiving box to send the cigarette into the qualified cigarette receiving box. Otherwise, the cigarette receiving trough rotates toward the defective cigarette receiving box to send the cigarette into the defective cigarette receiving box.

[0030] Furthermore, a cigarette sensor is provided on the cigarette receiving slot for detecting whether there is a cigarette in the cigarette receiving slot.

[0031] Furthermore, one end of the clamping member close to the cigarette receiving slot is an anti-slip roller sleeve.

[0032] Furthermore, the smoke separation mechanism comprises:

[0033] The smoke-distributing wheel is located at the lower exit of the silo, and has a number of smoke-distributing grooves evenly distributed on its surface, and a lower smoke port is provided at its bottom, and the cigarette clamping mechanism is located below the lower smoke port;

[0034] The cigarette removing roller is arranged above the cigarette separating wheel and is used for removing the excess cigarettes on the cigarette separating groove to ensure that there is only one cigarette in each cigarette separating groove.

[0035] Furthermore, the smoke separation mechanism also includes:

[0036] A cigarette separating wheel driving member, which is in driving connection with the cigarette separating wheel and is used to drive the cigarette separating wheel to rotate so as to convey cigarettes;

[0037] The cigarette removing roller driving member is drivingly connected to the cigarette removing roller and is used to drive the cigarette removing roller to remove excess cigarettes from the cigarette separating groove.

[0038] Working principle of the present invention:

[0039] When conducting appearance inspection of cigarettes, the cigarettes are placed in the hopper, and under the action of the cigarette sorting mechanism, the cigarettes are sent one by one into the cigarette clamping mechanism. When the cigarette falls from the outlet of the cigarette sorting mechanism onto the cigarette receiving trough (the cigarette sensor detects that there is a cigarette on the cigarette receiving trough), the clamping drive drives the three clamping members to close and clamp the filter tip of the cigarette. Then the clamping member rotation drive drives the clamping member to rotate, thereby driving the cigarette to rotate on the cigarette receiving trough. During the rotation process, the imaging mechanism obtains the image of the outer circumference of the cigarette in real time. After obtaining the complete image of the cigarette, the three clamping members open. If the cigarette is detected to be qualified, the cigarette receiving trough rotation drive drives the cigarette receiving trough to rotate toward the side of the qualified cigarette receiving box, and the cigarette is sent into the qualified cigarette receiving box; otherwise, the cigarette receiving trough rotates toward the side of the defective cigarette receiving box, and the cigarette is sent into the defective cigarette receiving box, completing the inspection of a cigarette.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The cigarette appearance inspection device provided by the present invention realizes the automatic transmission, clamping, inspection and sorting of cigarettes, effectively reduces the manual labor intensity, and greatly improves the efficiency of cigarette appearance inspection.

[0042] (2) The method of opening and closing clamping + roller-type toggling cigarette rotation can realize 360° rotation of the cigarette, so as to obtain a complete image of the cigarette appearance. This structure does not damage the appearance of the cigarette, the lower cigarette port is close to the cigarette receiving slot, and the probability of the cigarette falling out of the detection point is low.

[0043] (3) The cigarette sensor can detect whether there is a cigarette in the cigarette receiving slot, which can effectively prevent the next cigarette from entering the cigarette receiving slot before all cigarettes are detected, and prevent empty detection from occurring, thereby improving the reliability of the device.

Detailed implementation mode

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation modes.

[0057] Embodiment 1

[0058] As Figure 1 shown, this embodiment provides a cigarette appearance detection device, including: a silo 1, a smoke distributing mechanism 2, a cigarette clamping mechanism, an imaging mechanism (camera 5) and a recovery mechanism. Among them, the silo 1 is in a hopper - like structure, and its lower opening is docked with the smoke distributing mechanism 2. As Figures 2-3 shown, the smoke distributing mechanism 2 includes: a smoke distributing wheel 23 and a smoke pushing roller 25. The smoke distributing wheel 23 is driven by a smoke distributing wheel motor 21, and a number of smoke distributing grooves 24 are evenly distributed on its circumference. The smoke distributing grooves 24 are adapted to the cigarettes 8. A baffle 7 is arranged on one side of the smoke distributing wheel 23 close to the smoke distributing wheel motor 21, and the baffle 7 is used to protect the transmission parts of the smoke wheel motor 21 and the smoke pushing roller motor 22. The smoke pushing roller 25 is located in the smoke sending direction of the smoke distributing wheel 23, and it includes a smoke pushing shaft 251 and a number of anti - slip knurling 252 arranged on the smoke pushing shaft 251. The anti - slip knurling 252 is close to the wheel surface of the smoke distributing wheel 23. When the smoke distributing wheel 23 rotates, the smoke pushing shaft 251 rotates in the reverse direction, pushing the cigarettes 8 on the smoke distributing wheel 23 in the opposite direction, so as to ensure that there is only one cigarette 8 in the smoke distributing groove 24, that is, to ensure that only one cigarette 8 is detected each time later (only one cigarette 8 enters the receiving chute 42).

[0059] A smoke baffle 26 is arranged above the smoke pushing roller 25, and a protruding part is arranged on the smoke baffle 26, and the protruding part is located in the gap between two adjacent anti - slip knurling 252 to prevent the cigarette 8 from entering the gap between the smoke pushing roller 25 and the equipment housing.

[0060] Further, as Figures 4-7As shown in the figure, the cigarette clamping mechanism consists of a clamping part and a cigarette receiving part. Among them, the clamping part includes: a clamping motor 31, a clamping piece rotating motor 32, a fixed disk 33, a mounting disk 34 and three clamping pieces 35. Among them, the clamping motor 31 and the clamping piece rotating motor 32 are installed on the outer shell of the equipment. An external gear 341 and a mounting disk bearing 343 are sleeved on the outer circumference of the mounting disk 34, and three arc-shaped grooves 342 evenly distributed around the center are provided thereon. The mounting disk 34 is fixed to the external gear 341 through a front end cover 344 and a rear end cover 345. The front end cover 344 is located on the side close to the fixed disk 33, and the rear end cover 345 is located on the side of the external gear 341 and covers the external gear 341. Pins are provided on both the front end cover 344 and the rear end cover 345. The pin on the front end cover 344 passes through the mounting disk 34 and is fixed to the rear end cover 345, and the pin on the rear end cover 345 is fixed to the external gear 341. So that when the external gear 341 rotates, it can drive the mounting disk 34 to rotate in the mounting disk bearing 343, and then drive the clamping piece 35 to slide in the arc-shaped groove 342.

[0061] The fixed disk 33 is fixed to the bottom of the baffle 7, and three waist-shaped grooves 331 evenly distributed around the center are provided thereon. The three clamping pieces 35 respectively pass through the three waist-shaped grooves 331 and extend towards the cigarette receiving part. When the mounting disk 34 rotates, it drives the clamping pieces 35 to slide in the arc-shaped grooves 342 and the waist-shaped grooves 331, so that the three clamping pieces 35 open or close.

[0062] Furthermore, the three clamping pieces 35 are integrally distributed in a "pin" shape. Each clamping piece 35 includes: a clamping shaft 351, an anti-slip roller sleeve 352, a clamping shaft bearing 353 and a sub-gear 354. The clamping shaft 351 passes through the waist-shaped groove 331 and the arc-shaped groove 342. The anti-slip roller sleeve 352 (made of rubber) is detachably sleeved on one end thereof close to the cigarette receiving part. By replacing the anti-slip roller sleeves 352 with different diameters, the clamping pieces 35 can adapt to cigarettes with different diameters and specifications, avoiding the problems of damaging the cigarette due to too tight clamping or the cigarette falling due to too loose clamping. The sub-gear 354 is arranged at one end thereof passing through the arc-shaped groove 342. (When the three clamping pieces 35 are closed, the main gear 321 meshes with the three sub-gears 354 respectively). The sub-gear 354 is connected to the clamping piece rotating motor 32 through the main gear 321. The three clamping shafts 351 can be driven to rotate through the clamping piece rotating motor 32, and the cigarette 8 can be driven to rotate through the three anti-slip roller sleeves 352, so that the camera 5 can obtain a complete external image of the cigarette 8.

[0063] The cigarette receiving part includes: a cigarette receiving groove rotating motor 41, a cigarette receiving groove 42, and a cigarette sensor 43. The cigarette receiving groove rotating motor 41 is located on the opposite side of the clamping part rotating motor 32 and is fixed to the cigarette receiving groove 42 to drive the cigarette receiving groove 42 to rotate. The cigarette receiving groove 42 is integrally in the shape of an arc-shaped groove. One end of it close to the clamping part 35 is an opening, and a cigarette sensor 43 is arranged at the other end. The cigarette sensor 43 is used to detect whether there is a cigarette 8 in the cigarette receiving groove 42, which can effectively prevent the next cigarette 8 from entering the cigarette receiving groove 42 before the appearance of the previous cigarette 8 is completely detected, and prevent the situation of empty detection, thus improving the reliability of the device.

[0064] The camera 5 is installed on either side of the cigarette receiving groove 42 through a bracket. When the cigarette 8 falls into the cigarette receiving groove 42 and is clamped by the clamping part 35, it starts to acquire the appearance image of the cigarette 8 to be measured. After the cigarette 8 rotates 360°, a complete appearance image of the cigarette can be obtained.

[0065] Furthermore, the recycling mechanism includes a qualified cigarette receiving box 61 and a defective cigarette receiving box 62. The qualified cigarette receiving box 61 is located on one side of the cigarette receiving groove 42, and the defective cigarette receiving box 62 is located on the other side of the cigarette receiving groove 42. After the detection is completed, the clamping part 35 opens. According to the detection result, the cigarette receiving groove rotating motor 41 can drive the cigarette receiving groove 42 to rotate to sort the cigarette 8, that is: when the detected cigarette 8 is a qualified cigarette, the cigarette receiving groove 42 rotates to one side to pour the qualified cigarette 8 into the qualified cigarette receiving box 61; if it is a defective cigarette, the cigarette receiving groove 42 rotates to the other side to pour the defective cigarette 8 into the defective cigarette receiving box 62.

[0066] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention pertains, based on the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
