Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically to a device for testing the quality of cigarette carton packaging. Background Technology

[0002] During the production of cigarette packs, products with quality defects such as missing, damaged, or wrinkled transparent paper on the surface are often found to be flowing into the next process. If these defects are not detected in time, they will enter the market and damage the brand image. Therefore, it is necessary to inspect the appearance quality of the packaging boxes.

[0003] A review of utility model publication CN 213324066 U reveals a device for detecting loose cigarette pack transparent paper. This device includes a cigarette pack and transparent paper packaging channel, and a pair of fiber optic detection heads located at the front and rear ends of the transparent paper packaging channel. The pair of fiber optic detection heads face the ends and top folded corners of the transparent paper in the cigarette pack. This utility model can save materials and manpower, greatly improving product quality. However, it has the following drawbacks: it can only detect the ends of cigarette packs, limiting the detection range; furthermore, it requires manual removal of defective items, making the process cumbersome. Therefore, this utility model provides a cigarette pack packaging quality detection device to overcome the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a quality inspection device for cigarette carton packaging, in order to overcome the problems described in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cigarette carton packaging quality inspection device includes a conveying device and a housing. The housing has an inlet and an outlet on its front and rear sides, respectively. The conveying device passes through the inlet and its end is close to the outlet. A detection component for inspecting the appearance quality of the packaging box is installed in the housing. A partition is installed in the housing, and the partition and the inner wall of the housing form a defective cigarette carton cavity. A first cylinder is installed inside the housing. A guide plate is installed at the extension end of the first cylinder. The guide plate is inclined in the outlet and is located above the defective cigarette carton cavity. In the initial state, the upper end of the guide plate is tangent to the end of the conveying device.

[0007] Furthermore, baffles are provided on both sides of the feed hole, the baffles are located on both sides of the conveying device, and gratings are provided on the baffles.

[0008] Furthermore, a second cylinder, a controller, and an alarm device are provided on the top of the housing. The ejection end of the second cylinder is connected to a smoke baffle, which is located above the conveying device inside the housing. The second cylinder, the first cylinder, and the alarm device are electrically connected to the controller.

[0009] Furthermore, the detection component includes an optical fiber probe and a high-definition camera. The optical fiber probe is disposed on both sides of the housing, and the high-definition camera is disposed on the top inside the housing. A light source is also disposed on the top inside the housing. The optical fiber probe and the high-definition camera are electrically connected to the controller.

[0010] Furthermore, a wiping roller is rotatably disposed within the housing, and a sponge layer is disposed on the circumference of the wiping roller. A motor is disposed on the outside of the housing, and the motor is connected to one end of the wiping roller.

[0011] Furthermore, the outer wall of the housing is provided with a display screen and a defective discharge hole, the defective discharge hole is located on one side of the defective cigarette bar cavity and a door panel is hinged to the defective discharge hole.

[0012] Furthermore, the controller includes an optical fiber amplifier, a Beckhoff digital input module, a central processing unit, a Beckhoff controller, and a Beckhoff digital output module, which are electrically connected in sequence. The optical fiber probe is connected to the optical fiber amplifier, the high-definition camera is connected to the central processing unit, and the motor, the second cylinder, the first cylinder, and the alarm device are respectively connected to the Beckhoff digital output module.

[0013] Compared with the prior art, the present invention can achieve at least the following beneficial effects:

[0014] 1. This utility model sets the detection components inside the housing to avoid direct exposure to the outside, which would make them susceptible to light pollution and thus cause inaccurate detection. A second cylinder and a partition are set on the top of the housing. When the grating detects the arrival of the smoke strip, the partition temporarily blocks the delivery of the smoke strip to allow time for the fiber optic probe and high-definition camera to detect it and prevent the occurrence of ghosting.

[0015] 2. In this utility model, fiber optic probes are used to detect both ends of the cigarette bar, and high-definition cameras are used to capture images of the upper surface of the cigarette bar and transmit them to the backend for detection. Compared with existing methods that only use fiber optics for detection, this method improves the detection range.

[0016] 3. A guide plate is inclinedly installed at the discharge hole of the shell. The guide plate is pushed by the first cylinder and is tangent to the conveying device in the initial state, so that qualified parts can be discharged to the next station along the guide plate. When there are unqualified parts, the first cylinder pushes the guide plate upward, so that the unqualified parts fall into the unqualified cigarette bar cavity, thereby realizing the automatic rejection of unqualified parts.

[0017] 4. A wiping roller is provided at the feed hole of the housing to facilitate wiping the surface of the tobacco sticks entering the housing. Attached Figure Description

The optical fiber probe 5 is connected to the optical fiber amplifier 11a and is used to convert the detection signal of the optical fiber probe 5 into an electrical signal. The Beckhoff digital input module 11b is used to receive the electrical signal from the optical fiber amplifier 11a. A corresponding Beckhoff PLC control program is written in the Twincat software of the host computer. The high-definition camera 16 is connected to the central processing unit 11c. The central processing unit 11c has a built-in recognition model for identifying various defects in the appearance quality of the packaging box. The motor 4, the second cylinder 9, the first cylinder 13, and the alarm device are respectively connected to the Beckhoff digital output module 11e.

[0034] The working process of this utility model is as follows: the cigarette stick is conveyed on the conveying device 3 and the arrival of the cigarette stick is detected by the grating 18, thereby briefly opening the second cylinder for 2-3 seconds. The smoke baffle 19 moves downward to block the cigarette stick. At this time, the cigarette stick is detected by the fiber optic probe 5 and the image is acquired by the high-definition camera 16 and processed by the controller 11.
