Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging machine technology, and in particular to a cigarette rejection device. Background Technology

[0002] The tobacco industry has begun to fully adopt "box-carton-package" linkage technology to improve the tracking and verification capabilities of cigarettes. When consumers purchase cigarettes, they can scan the QR codes on the box, carton, and package to monitor the entire production process in real time, including raw material procurement, manufacturing, transportation, storage, and finally, the product reaches the consumer.

[0003] When an error occurs in the barcode detection station of cigarette cartons, the entire carton of cigarettes needs to be rejected in real time at the rejection station to avoid affecting the operation of the entire production line. Existing rejection devices typically use pneumatic push rods to achieve this function. However, due to the limited response speed of push rod structures, rejection may be delayed or incorrect when operating on high-speed production lines. Furthermore, to adapt to high-speed production lines, the pneumatic push rods require high driving air pressure, and the push rod structure can sometimes damage the cigarette cartons. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a smoke rejection device to solve the problem that the response speed of push rod-type structures in the prior art is limited, and that there is untimely rejection or misrejection when facing high-speed production lines.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a cigarette rejection device, which is set at the rear end of the barcode detection station of the cigarette conveyor line, includes a throwing wheel mechanism, a roller conveyor mechanism and a control module for triggering the rejection action of the throwing wheel mechanism in the cigarette conveyor line;

[0006] The throwing wheel mechanism includes a lifting platform and a roller rotatably mounted on the lifting platform. The roller is provided with multiple friction belts around its circumference, and the initial height of the roller is equal to the material conveying surface of the cigarette conveying line.

[0007] The roller conveyor mechanism includes a conveying channel perpendicular to the cigarette conveying line. The conveying channel is inclined downward in a direction away from the cigarette conveying line and is used to receive cigarettes rejected by the throwing wheel mechanism.

[0008] Optionally, the lifting platform is driven by a cylinder, and the roller is driven by a motor.

[0009] Optionally, the conveying channel consists of several parallel, freely rotatable rollers. This reduces sliding friction to rolling friction, allowing the initial throwing velocity of the rollers to be set lower.

[0010] Optionally, guide rails are provided on both sides of the conveying channel. These are used to guide and block the smoke from leaving the conveying channel.

[0011] Optionally, a baffle plate is provided at the end of the conveying channel.

[0012] Optionally, the control module includes a sensor for controlling the start and stop of the throwing wheel mechanism, a barcode reader and a controller installed at the barcode detection station of the cigarette pack conveyor line, with the sensor and the roller conveyor mechanism respectively installed on both sides of the cigarette pack conveyor line; the sensor and the cigarette pack barcode reader are both electrically connected to the controller, and the control module is connected to the control cabinet of the cigarette pack conveyor line.

[0013] The beneficial effects of this utility model are:

[0014] This invention achieves automatic rejection of cigarettes with abnormal barcode information by using a throwing wheel mechanism, a roller conveyor mechanism, and a control module for triggering the rejection action of the throwing wheel mechanism, all installed within the cigarette pack conveyor line. During the rejection process, the throwing wheel mechanism lifts the cigarette pack and, through the rollers, quickly provides it with an initial horizontal velocity and height for throwing into the conveyor channel. The conveyor channel consists of freely rotating rollers and has a downward slope, allowing the cigarette pack to smoothly slide to the center of the conveyor channel for rejection.

[0022] like Figures 1-4 As shown, this utility model discloses a cigarette rejection device, which is located at the rear end of the barcode detection station of the cigarette conveyor line 1. It includes a throwing wheel mechanism 2, a roller conveyor mechanism 3, and a control module for triggering the rejection action of the throwing wheel mechanism 2, all housed within the cigarette conveyor line 1. The cigarette conveyor line 1 is used to transport cigarettes. In this embodiment, it consists of a conventional symmetrically spaced belt or chain conveyor. The throwing wheel mechanism 2 is located in the gap in the middle of the conveyor and is used to lift and throw out erroneous cigarettes to the roller conveyor mechanism 3.

[0023] In this embodiment, the throwing wheel mechanism 2 includes a lifting platform 21 and a roller 22 rotatably mounted on the lifting platform 21. The roller 22 has multiple friction belts 23 circumferentially arranged. The friction belts 23 can be made of rubber or other materials that combine elasticity and friction to prevent the roller 22 from slipping and to avoid damage to the surface of the cigarette packs. The initial height of the roller 22 is slightly lower than the material conveying surface of the cigarette pack conveying line 1. The lifting platform 21 is driven by a cylinder, which is controlled to start and stop by a solenoid valve. The roller 22 is driven by a motor, such as a variable frequency motor. Driving and controlling the platform's lifting and lowering through cylinders and solenoid valves, and controlling and driving the roller's rotation through transmission structures such as motors, reducers, and pulleys, are all conventional existing technologies and will not be described in detail here.

[0024] In this embodiment, the roller conveyor mechanism 3 includes a conveying channel 31 perpendicular to the cigarette conveying line 1. The conveying channel 31 is inclined downwards in a direction away from the cigarette conveying line 1 and is used to receive cigarettes rejected by the throwing wheel mechanism 2. Specifically, the conveying channel 31 is composed of several parallel, freely rotatable rollers. Guide rails 32 are provided on both sides of the conveying channel 31. A baffle plate 33 is provided at the end of the conveying channel 31, and an elastic buffer block is provided on the baffle plate 33. The cigarettes are lifted by the throwing wheel mechanism 2 and thrown onto the conveying channel 31 composed of freely rotatable rollers. The initial velocity of the cigarettes and the slope of the conveying channel 31 allow the cigarettes to slide smoothly to the end of the conveying channel 31 and be stopped by the baffle plate 33.

[0025] In this embodiment, the control module includes a sensor 41 for controlling the start and stop of the throwing wheel mechanism 2, a barcode reader and a controller installed at the barcode detection station of the cigarette pack conveyor line 1. The sensor 41 and the roller conveyor mechanism 3 are respectively installed on both sides of the cigarette pack conveyor line 1. The sensor 41 and the cigarette pack barcode reader are both electrically connected to the controller, and the control module is connected to the control cabinet of the cigarette pack conveyor line 1, making full use of the existing production line and saving costs. The sensor 41 can be a common photoelectric sensor.

[0026] In this embodiment, when the cigarette barcode reader reads abnormal barcode information, it sends the abnormal barcode information to the controller. When the cigarette identified as having abnormal barcode information passes through the sensor 41, the sensor 41 sends an in-place signal to the controller, and the controller triggers the rejection action of the throwing wheel mechanism 2. When the cigarette identified as having abnormal barcode information is rejected and leaves the detection range of the sensor 41, the sensor 41 sends a departure signal to the controller, and the controller controls the throwing wheel mechanism 2 to reset.

[0027] The working principle of this utility model is as follows:

[0028] In use, the cigarette pack rejection device of this utility model is as follows: cigarette packs are conveyed on the cigarette pack conveyor line 1, and the barcode information affixed to the cigarette packs is identified by the barcode reader at the barcode detection station. When the cigarette pack barcode reader reads abnormal barcode information, it sends the abnormal barcode information to the controller. When the cigarette pack with abnormal barcode information passes through the sensor 41, the sensor 41 sends an in-place signal to the controller, and the controller triggers the rejection action of the throwing wheel mechanism 2. After the cigarette pack with abnormal barcode information is rejected and moves out of the detection range of the sensor 41, the sensor 41 sends a release signal to the controller, and the controller controls the throwing wheel mechanism 2 to reset.

[0029] During the rejection process, the roller 22 lifts the cigarette pack as the lifting platform 21 rises, causing the cigarette pack to detach from the conveying surface of the cigarette pack conveying line 1. At the same time, the roller 22 rotates rapidly, giving the cigarette pack a horizontal initial velocity and initial height for throwing it into the conveying channel 31. The conveying channel 31 is composed of freely rotating rollers and has a downward slope, allowing the cigarette pack to slide smoothly to the end of the conveying channel 31 and be stopped by the blocking plate 33.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
