Description

Technical Field

[0001] The utility model relates to the technical field of cigarette rod packaging and sorting, and more specifically, to a cigarette rod conveying system. Background Art

[0002] During the production process of cigarette equipment, in the cigarette rod packaging part, each shift and each unit will have cigarette rods with defects in appearance, and a few machines will have missing packs. All cigarette rods will pass through the uniform speed cigarette rod conveying channel to the carton sealing machine. If such defective cigarette rods flow into the carton sealing process, they will most likely flow directly into the market, which will affect consumers' perception or cause consumers to withdraw from the market, and will also affect the company's brand. In order to prevent such defective cigarette rods from flowing into the carton sealing process, cigarette rods with appearance defects currently use a cigarette rod appearance detector installed at the end of the packaging machine, but other appearance defects caused by transportation at the S lifting point have not been eliminated. Cigarette rods with missing packs currently use a photon missing pack detector installed at the S lifting point, but when the missing pack detector detects that the cigarette rod is missing a pack, it will send a stop signal to cause the packaging machine to stop. Production can only be resumed when the cigarette rods at the S lifting point are manually removed and the reset button is pressed. This method is time-consuming and labor-intensive, and it cannot ensure that the defective cigarette rods generated at the S lifting point can be completely eliminated, and it also reduces production efficiency.

[0041] Furthermore, the cigarette rod appearance detector 3 is installed above the cigarette rod conveying path 7 and in front of the cigarette rod rejection mechanism 1 through threaded fasteners. The image comparison principle is used to determine whether there are defects in the appearance of the cigarette rod, and the cigarette rod with appearance defects can be accurately identified. Five QR code recognition cameras 4 are installed at the front end of the cigarette rod appearance detector 3. Each QR code recognition camera 4 is responsible for an operation channel. The QR code recognition camera 4 can receive the information of the missing package QR code emitted by the photon missing package detector 2. The QR code will be re-marked and can also be associated with the cigarette rod passing through the cigarette rod appearance detector 3 by scanning. If the cigarette rod has appearance defects, the QR code will also be marked. The QR code information of all marked cigarette rods will be synchronized to the cigarette rod rejection mechanism 1.

In this embodiment, the photon package-missing detector 2 is installed on the S lifting channel through a U-shaped rod 22 and a cover plate 21. When the cigarette rod passes through the detection device, the photon emitting part sweeps and emits photons to penetrate the cigarette rod, and the photon receiving part receives the photons. Then the information processing part determines whether the cigarette rod is missing a package based on the received photons, and the missing cigarette rod can be accurately identified. A two-dimensional code recognition camera 4 is installed at the front end of the photon package-missing detector 2. The cigarette rod passing through the photon package-missing detector 2 will be scanned and associated by the two-dimensional code recognition camera 4.

[0044] When the cigarette rod conveying system is used:

[0045] When the cigarette rod passes through the photon missing pack detector 2 along the S lifting channel 8, it will automatically identify whether the cigarette rod is missing a pack. If it is missing a pack, the QR code of the missing cigarette rod will be marked by the QR code recognition camera 4. When the missing cigarette rod passes through the cigarette rod appearance detector 3 installed at the front end of the cigarette rod appearance detector 3 again, it will be recognized again by the QR code recognition camera 4 installed at the front end of the cigarette rod appearance detector 3. At this time, the cigarette rod rejection mechanism 1 enters the preparatory state; if the cigarette rod is not missing a pack, the appearance of the cigarette rod is detected to see if it is defective. When the cigarette rod passes through the cigarette rod appearance detector 3, the QR code of the cigarette rod is associated with the QR code recognition camera 4. If the appearance of the cigarette rod is defective, the cigarette rod is marked. At this time, the cigarette rod rejection mechanism 1 enters the preparatory state; the distance between the cigarette rod rejection mechanism 1 and the cigarette rod appearance mechanism is long enough. When the QR code recognition camera 4 installed in front of the pneumatic clamp 15 detects the marked cigarette rod QR code again, the double-rod pneumatic telescopic cylinder 14 moves quickly to the specified position. At this time, the pneumatic clamp 15 is just above the cigarette rod. The pneumatic clamp 15 quickly closes and retracts the double-rod pneumatic telescopic cylinder 14 to reach the highest distance, and quickly moves to the top of the S-shaped sliding track, dropping the defective cigarette rod into the V-shaped groove of the S-shaped sliding track, and the cigarette rod slides smoothly to the processing area.

[0046] The speed of the cigarette rods running uniformly on the cigarette rod conveying path 7 is set to v, and the lateral feed speed and longitudinal feed speed of the lateral feed guide rail 12 and the longitudinal feed guide rail 13 are greater than v. When the cigarette rods are rejected, if multiple defective cigarette rods need to be rejected at the same time, the first rejection time is T and the pneumatic clamp 15 of the cigarette rod rejection mechanism 1 is located at the front end position of the longitudinal feed guide rail 13, then the second preparatory state position of the pneumatic clamp 15 of the cigarette rod rejection mechanism 1 is the distance vt moved by the cigarette rod on the cigarette rod conveying path 7, that is, the preparatory rejection is carried out at the position where the longitudinal feed guide rail 13 moves backward a distance vt, and so on; the position where the rejection mechanism enters the first preparatory state is the limit position allowed by the longitudinal feed guide rail 13.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
