Description

Technical Field

[0001] The present disclosure belongs to the technical field of cigarette packagings, and particularly relates to a device for detecting the cutting effect of patterned inner lining paper. Background Art

[0002] The fixed-length and positioning cutting technology of the patterned inner lining paper applied to the ZB48 type packaging machine (which uses the direct wrapping technology of the inner lining paper) is based on the positioning color mark of the patterned inner lining paper, and uses the deviation rectifying roller component to control the position of the patterned inner lining paper to ensure the identity of the cutting position of the patterned inner lining paper. However, sometimes the deviation rectifying roller component does not control the position of the patterned inner lining paper accurately enough, and the inaccurate cutting position will cause the appearance of the lid end of the patterned inner lining paper not to meet the standard after the cigarette is wrapped into a box. Currently, there is no triggering device that enables the packaging unit control system to reject the cigarette packs with non-compliant patterned inner lining paper stacked on them, and prevent the cigarette packs with non-compliant patterned inner lining paper from flowing into the market. Summary of the Invention

[0003] The present disclosure proposes a device for detecting the cutting effect of patterned inner lining paper to solve the above technical problems.

[0004] A device for detecting the cutting effect of patterned inner lining paper includes: a camera fixed to the inner lining paper forming component for photographing the patterned inner lining paper after being cut; a controller for judging whether the distance between the top of the character on the patterned inner lining paper image and the cut edge of the patterned inner lining paper is within the qualified range based on the image of the patterned inner lining paper photographed by the camera.

[0005] In some embodiments, the inner lining paper forming component includes a cover plate; the device for detecting the cutting effect of the patterned inner lining paper further includes a detection device housing, which is in a cuboid shape and includes a rear side plate, a front transparent plate, a left side plate, a right side plate, a bottom plate, and a top plate. The camera is fixedly installed on the inner side of the rear side plate through a camera bracket, and the left side plate and the right side plate are respectively fixed on the cover plate of the inner lining paper forming component through corresponding connecting blocks.

[0006] In some embodiments, the bottom plate is provided with an avoidance hole, and a hemispherical light source for irradiating the patterned inner lining paper after being cut is arranged above the avoidance hole, and the camera photographs the patterned inner lining paper after being cut through the avoidance hole.

[0007] In some embodiments, a first bolt mating hole is formed at the rear end of the connecting block, and a second bolt mating hole is formed on the cover plate. The bolt mates with the first bolt mating hole and the second bolt mating hole to fix the rear end of the connecting block to the cover plate; a third bolt mating hole and a fourth bolt mating hole are respectively formed in the middle and the front end of the connecting block, and a fifth bolt mating hole and a sixth bolt mating hole are formed at the bottom of the right side plate. The bolt mates with the third bolt mating hole and the fifth bolt mating hole, and the bolt mates with the fourth bolt mating hole and the sixth bolt mating hole to fix the right side plate to the connecting block, so as to fix the right side plate to the cover plate of the inner liner paper forming part through the connecting block.

[0008] In some embodiments, the number of the cameras is two.

[0009] In some embodiments, the front transparent plate is made of quartz glass.

[0010] Advantages of the present disclosure: The camera photographs the patterned inner liner paper after being cut. The controller captures the topmost point of the pattern of the patterned inner liner paper and the cut edge of the patterned inner liner paper, calculates the vertical distance between the topmost point of the pattern and the cut edge, and determines whether the vertical distance is within the qualified range. If it is qualified, the packaging unit control system is not awakened. If it is unqualified, the packaging unit control system is awakened, and the cigarette packs with unqualified patterned inner liner paper stacked are removed. Among them, the reason for removal is that the cigarette packs are stacked with unqualified patterned inner liner paper after being cut. As a triggering device, on the one hand, this detection device can trigger the packaging unit control system to remove unqualified cigarette packs. On the other hand, when three cigarette packs (not specifically limited) are continuously removed, the packaging unit control system will control the packaging unit to stop for maintenance of the packaging unit.

[0015] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure.

[0016] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present disclosure, its application or use.

[0017] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the specification.

[0018] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0019] As Figure 1 and Figure 2 shown, a pattern inner liner paper cutting effect detection device includes a camera fixed on an inner liner paper forming member 6 for photographing the patterned inner liner paper 7 after being cut; a controller for determining whether the distance between the top of the character on the patterned inner liner paper image and the cut edge of the patterned inner liner paper is within a qualified range based on the image of the patterned inner liner paper photographed by the camera.

[0020] In some embodiments, the inner liner paper forming member includes a cover plate 1; the pattern inner liner paper cutting effect detection device further includes a detection device housing, the detection device housing is in a cuboid shape and includes a rear side plate, a front side transparent plate, a left side plate, a right side plate, a bottom plate, and a top plate. The camera is fixedly installed on the inner side of the rear side plate through a camera bracket, and the left side plate and the right side plate are respectively fixed on the cover plate of the inner liner paper forming member through corresponding connecting blocks.

[0021] In some embodiments, the bottom plate is provided with an avoidance hole, and a hemispherical light source for irradiating the patterned inner liner paper after being cut is arranged above the avoidance hole, and the camera photographs the patterned inner liner paper after being cut through the avoidance hole.

[0022] In some embodiments, a first bolt mating hole is formed at the rear end of the connecting block, and a second bolt mating hole is formed on the cover plate. A bolt is engaged with the first bolt mating hole and the second bolt mating hole to fix the rear end of the connecting block to the cover plate. Third and fourth bolt mating holes are respectively formed in the middle and front end portions of the connecting block, and fifth and sixth bolt mating holes are formed at the bottom of the right side plate. A bolt is engaged with the third bolt mating hole and the fifth bolt mating hole, and a bolt is engaged with the fourth bolt mating hole and the sixth bolt mating hole to fix the right side plate to the connecting block, so as to fix the right side plate to the cover plate of the inner liner paper forming member through the connecting block.

[0023] In some embodiments, the number of the cameras is two.

[0024] In some embodiments, the front transparent plate is made of quartz glass.

[0025] As a triggering device, the present disclosure wakes up the control system of the packaging unit and sends a rejection signal to the control system of the packaging unit when it detects that the distance from the topmost point of the pattern to the cut edge is not within the qualified range. The control system of the packaging unit rejects the unqualified cigarette packets to prevent the unqualified cigarette packets from entering the market. If three cigarette packets are continuously rejected, a stop signal is sent to the control system of the packaging unit, and the packaging unit stops.

[0026] After the camera finishes photographing the patterned inner liner paper after cutting, the obtained image is converted from a color image to a gray image by an image processing tool for subsequent detection.

[0027] The controller first uses an edge search tool to find the cut edge of the patterned inner liner paper, then uses a template search tool to locate the character features, and establishes the origin coordinates for calculating the distance at the topmost position of the character, and calculates the vertical distance from the origin to the cut edge to determine whether the patterned inner liner paper after cutting is qualified.

[0028] Such as Figure 2As shown, the controller first uses a search tool to find the trimmed edge of the patterned inner lining paper, and then uses the "template search" tool in the vision software to locate the characters (patterns or LOGOs). The template search tool slides the template and the original image by one pixel each time within the given search area for matching. After each movement, the similarity is calculated, and the best match is found based on algorithm parameters such as the lowest search score, the lowest passing score, and the number of searches. When the topmost position of the character is found, the origin coordinates for calculating the distance are established. Further, the distance d between the character (or pattern) and the trimmed edge is calculated. Based on the distance d, the controller determines whether the distance d is within the qualified range. If it is not qualified, an ejection signal is sent to the packaging unit control system. If three unqualified cigarette packs (not limited) are continuously ejected, then when the third ejection signal is sent, a stop signal is sent simultaneously, and the packaging unit is controlled to stop by means of the packaging unit control system.
