Description

Technical Field

[0001] The utility model relates to the technical field of cigarette detection, in particular to a cigarette strip rejecting and conveying device. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] During the cigarette production and packaging process, there is a certain probability that there will be insufficient cigarette packs in the cigarette cartons. This may be due to blockage in the cigarette pack conveying channel, loss during flipping and pushing, etc., which may lead to missing packs in the carton. Cigarette cartons with missing packs are not allowed to enter the market, but such defects cannot be completely eliminated during the production process.

[0004] The prior art arranges a missing box detection device on the outside of the carton conveying channel of the packaging machine. When a missing box of cigarette cartons is detected, the device sends out an alarm signal, but the missing box of cigarette cartons cannot be removed, and the machine operator can only stop the machine for processing. Since the missing box detection device is relatively high, the missing box of cigarette cartons can only be retrieved manually with a ladder. The processing is time-consuming, labor-intensive, and there is a risk of missing or wrong cigarette cartons, which affects product quality.

[0005] To solve the above problem, the prior art sets a collection box above the missing box detection device to remove the problematic cigarette cartons and collect them into the collection box. Since the collection box is set above the missing box detection device, although the number of retrieval times is reduced, manual climbing is still required to retrieve them, resulting in low work efficiency.

[0035] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0036] As introduced in the background technology, in the prior art, when the packaging machine performs box shortage detection, the device can only send out an alarm signal and cannot remove the missing box cigarette cartons, or manual labor is required to climb up to retrieve the missing box cigarette cartons, which is time-consuming and labor-intensive. In order to solve the above technical problems, the utility model proposes a cigarette cartons removal and conveying device.

[0037] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0038] A cigarette strip rejecting and conveying device comprises: a cigarette strip conveying channel 1, a box-missing detection device 2, a rejecting device 3, a box-missing cigarette strip conveying device 4 and a frame 5, wherein the cigarette strip conveying channel 1, the box-missing detection device 2, the rejecting device 3 and the box-missing cigarette strip conveying device 4 are all fixed on the frame 5.

[0039] A conveyor belt 11 is arranged in the cigarette conveying passage 1 for conveying cigarettes. A box-missing detection device 2 is fixed on the cigarette conveying passage 1 for detecting whether a cigarette passing through is missing a box. A rejection device 3 is arranged above the box-missing detection device 2. The rejection device 3 and the box-missing cigarette conveying device 4 are arranged on both sides of the cigarette conveying passage 1. The box-missing cigarette conveying device 4 comprises a slide rail 42 and a long arm 43. The long arm 43 is slidably connected to the slide rail 42. The long arm 43 slides up and down relative to the slide rail 42 to convey the box-missing cigarette from a high place to a low place.

[0040] When the rejecting device 3 pushes the missing cigarette cartons into the missing cigarette cartons conveying device 4, the missing cigarette cartons conveying device 4 drives the missing cigarette cartons to move downward, thereby moving the missing cigarette cartons from a high place to a low place for easy taking.

[0041] Optionally, the cigarette conveying channel 1, the missing box detection device 2 and the rejection device 3 are fixed to the frame 5 by brackets and screws, or other reasonable structures can be used for fixing, which is the prior art here.

[0042] Optionally, the missing box detection device 2 is configured as a photon missing box detection device 2, which includes a photon emitter and a photon receiver, which are respectively arranged on both sides of the cigarette transport channel 1, and the photon emitter and the photon receiver are fixed on the skeleton 5 through a bracket. The photon emitter transmits a light signal to the photon receiver, and when the cigarette 6 passes through, the light signal changes. The photon detection device determines whether there is a missing package in the box body by the change of the light signal, which belongs to the prior art and will not be elaborated here.

[0043] Optionally, the rejection device 3 includes a propulsion cylinder 31, which is fixed to the skeleton 5 via a propulsion cylinder fixing frame 32. The propulsion cylinder fixing frame 32 is a bracket for fixing the propulsion cylinder 31 to fix the propulsion cylinder 31 to the skeleton. The propulsion cylinder 31 includes a piston rod extending toward the conveyor belt 11, and the piston rod is arranged parallel to the conveyor belt 11, that is, the distance between the two ends of the piston rod is equal to the distance between the conveyor belt 11, and the distance between the piston rod and the conveyor belt 11 is less than the height of the cigarette box. When the piston rod is extended, the missing cigarette box is pushed out of the cigarette conveying channel 1 to the cigarette receiving rack 44.

[0044] Optionally, a fixed structure is provided at the top of the slide rail 42 of the missing box cigarette conveying device 4, the rotating shaft 41 is perpendicular to the side of the frame 5, and the fixed structure is rotatably connected to the frame 5 via the rotating shaft 41. The missing box cigarette conveying device 4 also includes a transverse cylinder 46, which is fixed to the frame 5 and arranged on one side of the slide rail 42. The free end of the piston rod of the transverse cylinder 46 contacts one side of the slide rail 42. The piston rod of the transverse cylinder 46 extends to push the slide rail 42 to rotate along the rotating shaft 41. The piston rod is retracted to restore the slide rail 42 to its original position after losing the thrust, and the piston rod is extended to realize the swing of the slide rail 42 around the rotating shaft 41.

[0045] Optionally, the missing-box cigarette conveying device 4 includes a sliding cylinder 45 , which is fixed on the slide rail 42 through the above-mentioned fixing structure. The sliding cylinder 45 is arranged at the upper end of the slide rail 42 and fixedly connected to the upper end of the long arm 43 .

[0046] When the pushing mechanism pushes the cigarettes to the cigarette receiving rack 44, the piston rod of the transverse cylinder 46 extends to push the slide rail 42 to rotate around the rotating shaft 41 for a certain angle, and the sliding cylinder 45 pushes the long arm 43 to move downward along the slide rail 42, so that the cigarette receiving rack 44 moves downward.

[0047] Optionally, a cigarette receiving rack 44 is fixedly provided at the lower end of the long arm 43 , and the cigarette receiving rack 44 is used to accommodate cigarette cartons with missing boxes, and is arranged opposite to the propulsion cylinder 31 when the cigarette cartons with missing boxes conveying device 4 is in a standby state.

[0048] Optionally, the cigarette receiving rack 44 is a cage-shaped or box-shaped structure, and an opening is provided on one side close to the cigarette conveying channel 1, which is the cigarette receiving rack opening 47, which is the prior art.

[0049] Optionally, the relative positions of the cigarette receiving rack 44 and the propulsion cylinder 31 are such that gaps 12 are provided on both sides of the cigarette transport device, so as to facilitate the propulsion cylinder 31 to push the missing cigarette cartons into the cigarette receiving rack 44 .

[0050] Optionally, a controller is also included. The missing box detection device 2 detects whether the cigarette carton is missing a box and uploads a signal to the controller. The controller is used to receive the uploaded signal and send a signal to the rejection device 3 and the missing box cigarette carton conveying device 4. The rejection device 3 is used to receive the signal sent by the controller and push the missing box cigarette carton to the cigarette receiving rack 44. The missing box cigarette carton conveying device 4 is used to receive the signal sent by the controller and move the missing box cigarette carton to a lower place.

[0051] During operation, driven by the conveyor belt 11, the cigarette carton 6 moves upward along the cigarette carton conveying channel 1. When the cigarette carton passes through the photon box-missing detection device 2, the box-missing detection device 2 detects whether the cigarette carton is missing a box. When the cigarette carton is missing a box, the telescopic rod of the propulsion cylinder 31 of the rejection device 3 extends to push the cigarette carton without a box to the cigarette receiving rack 44. At this time, the piston rod of the transverse cylinder 46 of the box-missing cigarette carton conveying device 4 extends to push the slide rail 42 to rotate a certain angle until the extension line of the slide rail 42 does not pass through the box-missing detection device 2. At this time, the sliding cylinder 45 pushes the long arm 43 to move downward along the slide rail 42, so that the cigarette receiving rack 44 moves downward, thereby moving the cigarette carton without a box to a lower place.

[0052] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
