Description

Technical Field

[0001] This utility model belongs to the field of cigarette packaging production technology, specifically relating to a device for detecting the aluminum foil strip pull of small boxes. Background Technology

[0002] See Figure 1 During the cigarette pack production process, packs often deform at the junction of the second and third rolling mills, requiring the rejection of defective packs. Based on the existing equipment's principle, the second rolling mill is equipped with an inner lining paper detection system, primarily using a photoelectric detector to check for lining misalignment and the presence of packs with missing linings. The third rolling mill inlet is equipped with a pull tab detection system, using a photoelectric detector to check for missing pull tabs on the packs. Figure 2 The location of the pull tab is shown. Packets with either of these two quality defects will be rejected at the third pull wheel.

[0003] However, existing equipment does not have a design to detect deformation of the inner lining paper or wrinkles and missing corners of the cigarette pack in the second and third wheel sections. When the inner lining of the cigarette pack is intact but the inner lining paper and pull tab have the above-mentioned problems, it cannot be effectively detected. If cigarette packs that do not meet the quality requirements continue to be conveyed forward, it will cause a product quality accident. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the pull tabs of small aluminum foil sheets, in order to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model provides a device for detecting the pull tabs of aluminum foil in small boxes, comprising:

[0006] Outer guide plates and inner guides are located on both sides of the tobacco pack conveying channel;

[0007] An external inspection component, mounted on the outer guide plate, is used to detect defects on the outer end face of the cigarette pack;

[0008] The internal inspection component, installed on the inner guide plate, is used to detect defects on the inner end face of the cigarette pack.

[0009] In one embodiment of this application, the external detection component includes:

[0010] Two phototubes positioned at an angle of 30-60 degrees cover the outer surface of the cigarette pack in their detection range.

[0011] Fiber optic sensors are used to detect key defects in sheet pulling; among which...

[0012] Both the first phototube and the fiber optic sensor are connected to the control module, and the fiber optic sensor is also used to trigger the first phototube detection.

[0013] In one embodiment of this application, the two first phototubes are at a 45-degree angle.

[0014] In one embodiment of this application, the internal detection component includes two second phototubes at an angle of 30-60 degrees, the detection range of which covers the inner end face of the cigarette pack.

[0015] In one embodiment of this application, the two second phototubes are at a 45-degree angle.

[0016] In one embodiment of this application, the external detection component further includes a first housing, and the first phototube and the fiber optic sensor are disposed within the first housing;

An internal detection component on the inner guide plate can detect defects in the packaging paper on the outer end face of the cigarette pack, thus improving the comprehensiveness of cigarette pack inspection. The optimized layout using high-precision photocells arranged at an angle reduces the installation volume while increasing the detection coverage area, reducing missed and false detections and ensuring product quality.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] In existing equipment, the photoelectric detector is directly mounted on the outer guide plate. When the tobacco pack is propelled by the second wheel to the third wheel, the pack follows a linear trajectory. The photoelectric detector is located at the pull tab position, and its detection range is limited to the installation position of the photoelectric sensor. This limits the detection range and accuracy. Missing pull tabs can only be detected at the linear position sensed by the photoelectric detector. Wrinkles, folds, and missing corners on the pull tabs cannot be detected.

[0042] See Figure 3 and Figure 4 In one embodiment of this application, the device for detecting the aluminum foil pull tab of the small box includes: an outer guide plate 11 and an inner guide plate 12 located on both sides of the cigarette pack conveying channel 1; an outer detection component 2, installed on the outer guide plate 11, for detecting defects on the outer end face of the cigarette pack; and an inner detection component 3, installed on the inner guide plate 12, for detecting defects on the inner end face of the cigarette pack.

[0043] In this embodiment, by setting an external detection component 2 on the outer guide plate 11, it can be used to detect the presence or absence of the pull tab and the defects of the pull tab on the outer end face of the cigarette pack (i.e. the end face where the pull tab is located). By setting an internal detection component 3 on the inner guide plate 12, it can be used to detect defects in the packaging paper on the outer end face of the cigarette pack, thereby improving the comprehensiveness of the cigarette pack detection.

[0044] For details, see Figure 5 The external detection component 2 includes: two first phototubes 21 with an angle of 30-60 degrees, whose detection range covers the outer end face of the cigarette pack; and an optical fiber sensor 22 for detecting key defects in the cigarette pack; wherein the first phototubes 21 and the optical fiber sensor 22 are both connected to the control module, and the optical fiber sensor 22 is also used to trigger the first phototubes 21 to detect.

[0045] In this embodiment, by installing the two first phototubes 21 at a certain angle, their detection surfaces cover the end face of the cigarette pack pull tab, thus expanding the detection range and making the detection surface wider. This allows for the detection of missing or wrinkled pull tabs in the cigarette pack. The fiber optic sensor 22 can be installed at a specific location for the presence or absence of the pull tab. It can serve as both a trigger detection basis and a measure to detect the presence or absence of the pull tab, providing an extra layer of detection protection for areas prone to defective products.

[0046] Preferably, the two first phototubes 21 can be at a 45-degree angle.

[0047] See Figure 6 Furthermore, the internal detection component 3 includes two second phototubes 31 arranged at an angle of 30-60 degrees, whose detection range covers the inner end face of the cigarette pack.

[0048] In this embodiment, the inner detection component 3 is a newly added detection component on the original equipment. It includes two second phototubes 31 with an angle of 30-60 degrees, and the layout of the detection surface covers the inner end face of the cigarette pack, which expands the detection range, ensures product quality, and forms an overall detection system with the outer detection component 2, which can comprehensively detect defects in the cigarette pack packaging paper.

[0049] Preferably, the two second phototubes 31 are at a 45-degree angle.

[0050] See Figure 4 and Figure 5 Optionally, the external detection component 2 further includes a first housing 23, in which the first phototube 21 and the fiber optic sensor 22 are disposed; the outer guide plate 11 is provided with a first mounting hole 111 for accommodating the first housing 23.

[0051] Optionally, the internal detection component 3 further includes a second housing 32, and the second phototube 31 is disposed inside the second housing 32; the inner guide plate 12 is provided with a second mounting hole 121 for accommodating the second housing 32.

[0052] In this embodiment, the detection components of the outer detection component 2 are housed within the first housing 23, exhibiting high integration and modularly mounted on the outer guide plate 11; similarly, the inner detection component 3 can be modularly mounted on the inner guide plate 12.

[0053] In this embodiment, see Figure 5 , Figure 7 , Figure 8 , Figure 9 The fiber optic sensor 22 is installed in the adjusting mounting sleeve 24 with a self-aligning structure, which facilitates the adjustment of the detection position of the fiber optic sensor 22.

[0054] Specifically, the first housing 23 is provided with an adjustment sleeve mounting hole 231, into which the adjustment sleeve 24 can pass; the side wall of the first housing 23 is provided with a fastening hole 232 communicating with the adjustment sleeve mounting hole 231, for fasteners 233 to pass through and abut against the adjustment sleeve 24; the adjustment sleeve 24 is provided with an eccentrically arranged fiber optic sensor receiving hole 241, and the tail end of the adjustment sleeve 24 is provided with a rotation groove 242.

[0055] In this embodiment, the fiber optic sensor 22 can be fixed in the fiber optic sensor receiving hole 241. During adjustment, the adjusting mounting sleeve 24 can be rotated by inserting a tool into the groove 242. Since the fiber optic sensor 22 is eccentrically mounted, its detection height can change accordingly. After rotating to the preset detection height, the adjusting mounting sleeve 24 can be tightened by the fastener 233 to fix the position of the adjusting mounting sleeve 24.

[0056] In this embodiment, optionally, the inner surfaces of the outer guide plate 11 and the inner guide plate 12 facing the direction of the cigarette pack feeding are provided with guide slopes 13.

[0057] In summary, the device for detecting small aluminum foil sheet pull tabs of this utility model adopts an optimized layout of high-precision phototubes arranged at an angle, which reduces the installation volume and increases the detection coverage area, thereby reducing missed and false detections and ensuring product quality. The integrated fiber optic installation and adjustment structure reduces modifications to the original device, and the photoelectric detection waveform allows for faster evaluation of the detection results, reducing the detection and evaluation time and broadening its adaptability.
