Description

Technical Field

[0001] The utility model relates to the field of cigarette manufacturing, in particular to a device for inspecting and packaging the appearance of small packages of medium-sized cigarettes. Background Art

[0002] During the cigarette packaging production process, in order to improve product quality and prevent defective cigarette packs from flowing into the next process, after the cigarettes are packaged in small boxes, visual inspection devices are generally used to inspect the appearance of the cigarette packs, so as to detect products with defects in the appearance of the cigarette packs and remove them to prevent defective products from flowing into the next process.

[0003] Existing small-pack appearance inspection devices are installed on the conveyor channel at the packaging machine's exit. To avoid interference, they ensure that only a single cigarette pack is present during each photo inspection. Therefore, a pack separation device is typically installed at the inspection entrance to separate adjacent cigarette packs that are unevenly spaced on the conveyor channel. This ensures that the distance between cigarette packs is consistent after entering the visual inspection process, thereby ensuring the reliability of visual inspection.

[0004] Existing small-packaging devices usually use two upright belts to clamp the cigarette packs, and the packs are divided by the friction between the cigarette packs and the left and right packing belts.

[0005] However, it has been found through practical application that the existing technical solutions have at least the following disadvantages:

[0006] (1) The tension of the left and right subcontracting belts needs to be adjusted separately, and it is difficult to ensure the consistency of the tension on the left and right sides, which makes the installation and debugging of the subcontracting device inconvenient.

[0007] (2) The transmission method that relies on belts to clamp cigarette packs and realize sub-packaging will cause the cigarette packs located in the middle of the belts to be squeezed and deformed due to the close distance between the two belts. If the distance between the two belts is too far, the friction will be reduced, making it difficult to effectively sub-pack.

[0008] (3) In addition, the existing belt-clamped cigarette packing method is only applicable to the vertical packing method of cigarette packs, and the existing packing method cannot be expanded for the horizontal packing method of cigarette packs. Utility Model Content

[0027] Figure 2 This is a partial schematic diagram from another angle of the device for appearance inspection and packaging of medium-sized cigarette packets provided by an embodiment of the utility model. DETAILED DESCRIPTION

[0028] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] The utility model proposes an embodiment of a device for detecting and packaging small packages of medium-sized cigarettes. Specifically, Figure 1 and Figure 2 As shown, it includes: a servo motor 1, a transmission pulley 2, a tensioning mechanism, a left subpackaging mechanism, a right subpackaging mechanism, a toothed belt 9 and an adjusting screw 15; wherein the transmission pulley 2, the tensioning mechanism, the left subpackaging mechanism and the right subpackaging mechanism are connected through the toothed belt 9.

[0030] In practice, four M5 screw holes are provided at the four corners of the servo motor 1, allowing the motor to be secured to the mainframe using four M5 hexagon socket screws. The drive pulley 2 is secured to the servo motor 1's main shaft via an M3 hexagon socket flat-head screw, allowing it to rotate synchronously with the motor's main shaft. To accommodate different installation scenarios, a coupling with a 12mm inner diameter can be used when the inner diameter of the drive pulley 2 does not match the motor shaft.

[0031] The tensioning mechanism includes a tensioning pulley 3 and a tensioning shaft 4. The tensioning shaft 4 is fixed to the main machine base through an M5 hexagon socket countersunk screw. The tensioning pulley 3 can be fixed to the tensioning shaft 4 through an M3 hexagon socket flat head screw and rotates around the shaft.

[0032] The left sub-packaging pulley 5, the left sub-packaging shaft 6, the left sub-packaging connecting block 7 and the left sub-packaging rubber wheel 8 together constitute the left sub-packaging mechanism, and the left sub-packaging pulley 5 and the left sub-packaging rubber wheel 8 are axially connected through the left sub-packaging connecting block 7 by the left sub-packaging shaft 6; the right sub-packaging pulley 10, the right sub-packaging shaft 11, the right sub-packaging connecting block 12 and the right sub-packaging rubber wheel 13 together constitute the right sub-packaging mechanism, and the right sub-packaging pulley 10 and the right sub-packaging rubber wheel 13 are axially connected through the right sub-packaging connecting block 12 by the right sub-packaging shaft 11; in some preferred embodiments, the left sub-packaging connecting block 7 and the right sub-packaging connecting block 12 are fixed to the mounting bracket (not shown in the figure) on the corresponding side through a sliding guide rail (not shown in the figure).

[0033] Continuing from the above, the adjusting screw 15 is arranged between the left subpackaging mechanism and the right subpackaging mechanism. Specifically, a left-handed thread is provided inside the left subpackaging connecting block 7, and a right-handed thread is provided inside the right subpackaging connecting block 12. When the adjusting screw 15 rotates clockwise, the left subpackaging mechanism (5, 6, 7, 8) and the right subpackaging mechanism (10, 11, 12, 13) can be driven to move toward the middle along the axis of the adjusting screw 15, that is, the distance between the left subpackaging rubber wheel 8 and the right subpackaging rubber wheel 13 is reduced; conversely, when the adjusting screw 15 rotates counterclockwise, the distance between the left subpackaging rubber wheel 8 and the right subpackaging rubber wheel 13 increases, so that the gap between the subpackaging rubber wheel and the cigarette pack can be adjusted. By adjusting the spacing through the thread, the distance between the subpackaging rubber wheel and the cigarette pack can be accurately adjusted. In order to make the adjustment operation more reliable, the locking nut 16 (a hexagonal nut with a diameter of 13 mm) can be used to lock the adjusting screw 15 when the sub-packaging device is adjusted to a suitable position to prevent the adjusting screw 15 from rotating and changing the gap between the left and right sub-packaging rubber wheels and the cigarette packs.

[0034] In other preferred embodiments of the present invention, it also includes: a subpackaging guide shaft 14 and a subpackaging pressure wheel 17; the two ends of the subpackaging guide shaft 14 are arranged between the left subpackaging mechanism and the right subpackaging mechanism, specifically, can pass through the left subpackaging connecting block 7 and the right subpackaging connecting block 12; and the subpackaging pressure wheel 17 is installed on the subpackaging guide shaft 14 and contacts one side of the cigarette package, so that the subpackaging pressure wheel 17 can rotate axially, and can rotate with the cigarette package when the cigarette package passes through the subpackaging device. On the one hand, it plays a guiding role, and on the other hand, it can prevent the cigarette package from being bulged and deformed in the middle of the cigarette package due to the subpackaging operation during the friction between the structures on both sides.

[0035] Finally, in combination with the above embodiments, the working method of the present invention is schematically introduced here: when the appearance inspection of small packages is in progress, the conveyor belt transports cigarette packages from left to right in the figure, and the packaging device starts to work. The servo motor 1 drives the transmission pulley 2 to rotate clockwise, and the toothed belt 9 also rotates clockwise under the drive of the transmission pulley 2, thereby driving the tensioning mechanism (3, 4), the right packaging mechanism (10, 11, 12, 13) to rotate clockwise, and the left packaging mechanism (5, 6, 7, 8) to rotate counterclockwise; the rotation of the left and right packaging rubber wheels transports the cigarette packages forward at a uniform speed. The speed of the servo motor can be pre-set so that the rotation speed of the packaging rubber wheels is less than the speed of the cigarette package conveyor belt. After the cigarette packages pass through the packaging device, the cigarette packages will be staggered by a certain distance. Of course, those skilled in the art will understand that the minimum distance can be determined by the speed difference between the servo motor and the conveyor belt. Therefore, it can be set according to actual needs, thereby effectively achieving packaging and avoiding two or more consecutive cigarette packages being too close to each other on the belt, which will affect the subsequent appearance inspection effect.

[0036] In summary, the main design concept of the present invention is that it includes a servo motor, a transmission pulley fixed on the main shaft of the servo motor, a tensioning mechanism, a left sub-packaging mechanism, a right sub-packaging mechanism, a toothed belt and an adjusting screw; wherein the transmission pulley, the tensioning mechanism, the left sub-packaging mechanism and the right sub-packaging mechanism are connected by a toothed belt transmission; the left sub-packaging mechanism and the right sub-packaging mechanism are respectively arranged on both sides of the appearance inspection conveyor belt, for frictionally contacting the left and right sides of the passing cigarette packs; the adjusting screw is passed between the left sub-packaging mechanism and the right sub-packaging mechanism, for adjusting the distance between the left sub-packaging mechanism and the right sub-packaging mechanism. The present invention does not affect the operation of the original equipment mechanism, nor does it require changes to the original parts, and can effectively sub-pack the flat-packed cigarette packs, and can also make the distance between adjacent cigarette packs equal, while reducing the risk of damage to the cigarette packs, ensuring that the cigarette pack images collected each time are clear and interference-free, thereby providing a stable condition basis for subsequent appearance imaging detection and defect removal.
