Description

Technical Field

[0001] The present invention relates to a device for detecting cigarette pack inversion during a cigarette production process using mechanical equipment, and more particularly, to a device for detecting special-shaped cigarette pack inversion. Background Art

[0002] During the cigarette pack production process, manual labor is inevitably involved in picking, removing, and adding cigarette packs on the conveyor line. This creates the possibility of cigarette packs being placed upside down, leading to quality defects in downstream packaging. Therefore, it is necessary to detect and promptly correct this inversion. Currently, known methods for detecting cigarette pack inversion generally use visual inspection systems or optical color difference detectors. The former uses a high-speed camera to capture an image and then compares it with system settings to detect pack anomalies. The latter uses color differences on specific surfaces of the pack to determine pack anomalies. The former is expensive, while the latter is more widely used. On current, common cigarette packaging equipment, when a product is at a fixed phase, the color difference detector's base surface is always in a fixed position. Therefore, under this characteristic, products with significant surface differences are easily identified by the inspection system.

[0003] However, the emergence of innovative flavor- and moisture-preserving products has challenged traditional cigarette pack inspection methods. These products typically have pure white inner packaging with an open top and a U-shaped notch on the front that reveals the filter surface. Since these products come in multiple series, each series has a different color of filter tipping paper. Consequently, using traditional visual inspection systems or optical color difference detectors would require system configuration and adjustment with each product change. This can also lead to false detection or failure if the filter tipping paper color is similar or identical to the packaging paper. Summary of the Invention

[0004] The present invention overcomes the shortcomings of the prior art and provides an implementation method of a device for detecting the inversion of irregular-shaped cigarette packages, in the hope of solving the quality risk of innovative cigarette packages being easily inverted in the input channel of an RC transparent paper / aluminum-plastic paper packaging machine.

A plexiglass plate is provided above the conveying channel and a conveyor belt is provided below the conveying channel. A device mounting hole is provided on the plexiglass plate. The device mounting hole is connected to the base plate by bolts. A device detection window is provided at the lower end of the plexiglass plate where the device is installed. The device detection window can be larger than the detection opening.

[0011] The position of the bracket adjustment rod mounting hole is lower than the horizontal line of the bracket guide rod mounting hole.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 1 、 Figure 2 、 Figure 3As shown, the irregular cigarette package inversion detection device comprises a top plate 1, a bottom plate 2, an outer plate 3, and an inner plate 4. The top plate 1 and bottom plate 2 are made of plexiglass, while the outer plate 3 and inner plate 4 are made of aluminum. The top plate 1 and bottom plate 2 are connected by the outer and inner plates on either side. Optionally, the irregular cigarette package inversion detection device is 90 mm long, 65 mm wide, and 103 mm high, forming a single mounting cavity within the entire device. Two height adjustment rod mounting holes are horizontally provided on the top plate 1, and the two height adjustment rod mounting holes are long holes; the left height adjustment rod 5 and the right height adjustment rod 6 are respectively installed in the two height adjustment rod mounting holes, and the two height adjustment rods are made of 45# steel. The diameter of the two height adjustment rods is smaller than the diameter of the height adjustment rod mounting hole. The upper end of the height adjustment rod is set at the upper end of the top plate, and the lower end is set in the mounting cavity. The rocker arm support frame 8 is adjusted by adjusting the height of the height adjustment rod; the two height adjustment rods are screws, and the upper ends are respectively provided with limit nuts 7, and the limit nuts 7 are made of 45# steel; the limit nuts 7 are set at the upper end of the top plate to limit the downward movement of the height adjustment rod. A rocker support frame 8 is provided in the installation cavity. The rocker support frame 8 is made of 45# steel. The lower ends of the left height adjustment rod 5 and the right height adjustment rod 6 are threadedly connected to the rocker support frame 8. The left height adjustment rod 5 and the right height adjustment rod 6 in the installation cavity are respectively sleeved with an adjusting rod spring 9 (tension spring), and the adjusting rod spring 9 is an ordinary soft spring; two bracket guide rod mounting holes that pass through the rocker support frame 8 are provided on the same horizontal line of the side wall of the rocker support frame 8, and a bracket adjustment rod mounting hole that passes through the rocker support frame 8 is provided between the two bracket guide rod mounting holes, and the position of the bracket adjustment rod mounting hole is lower than the horizontal line of the bracket guide rod mounting hole; mounting holes are provided on the outer plate 3 and the inner plate 4 respectively corresponding to the bracket guide rod mounting hole and the bracket adjustment rod mounting hole, and the mounting holes provided on the outer plate and the inner plate The holes are vertically arranged elongated holes. A support guide rod 10 is mounted in each of the two support guide rod mounting holes. The ends of the support guide rod 10 extend through corresponding mounting holes on the outer and inner plates, respectively. A support guide rod spring 22 is mounted on the support guide rod 10. The support guide rod spring 22 is a common soft spring (compression spring) that ensures flexible movement of the detection rod 14. The support guide rod spring 22 is mounted in the support guide rod mounting hole. A support adjustment rod 12 is mounted in the support adjustment rod mounting hole. The ends of the support adjustment rod 12 extend through corresponding mounting holes on the outer and inner plates, respectively. The ends of the support guide rod 10 and support adjustment rod 12 are threaded rods. Adjustment nuts 13 are mounted on the protruding ends of the support guide rod 10 and support adjustment rod 12 on the outer and inner plates, respectively. Under the action of the support guide rod 10 and adjustment rod spring 9, the rocker arm support frame 8 can move up and down. Under the action of the support adjustment rod 12 and support guide rod spring 22, the rocker arm support frame 8 can flexibly swing along the axis of the support adjustment rod.

[0025] A swing arm 23 is movably mounted on the bracket adjustment rod 12. The swing arm 23 is disposed between the swing arm support frame 8 and the inner plate 4. The swing arm 23 is able to rotate freely on the bracket adjustment rod 12. A swing light baffle 16 is fixedly mounted on the upper end of the swing arm 23 via screws. A detection rod 14 is disposed at the lower end of the swing arm 23. The swing light baffle 16 swings with the swing of the detection rod 14. The swing light baffle 16 is hardened to prevent deformation, and the detection rod 14 is also hardened to prevent deformation. A detection opening 15 is provided on the base plate 2 at a position corresponding to the detection rod 14. The detection opening 15 is rectangular or square to ensure that the detection rod 14 is usable.

[0026] The outer plate 3 and the inner plate 4 are respectively provided with optical fiber head mounting holes, and the two optical fiber head mounting holes are horizontally arranged long strip holes. Optical fiber heads 17 are respectively installed in the two optical fiber head mounting holes, and the optical fiber heads 17 are connected to optical fiber signals; a swinging light baffle 16 is arranged between the two optical fiber heads 17. During use, the detection rod 14 drives the swinging light baffle 16 to move left and right to cut off and connect the optical fiber signal of the optical fiber head 17; when the detection rod 14 is above the cigarette of the U-shaped notch cigarette pack 11, the swinging light baffle 16 is in the state of blocking the optical fiber signal of the optical fiber head 17, and the optical fiber signal is in a cut-off state. When the detection rod 14 contacts other surface positions of the cigarette pack, the swinging light baffle 16 tilts in the direction of the limit plate 19 to connect the optical fiber head signal, and compares the length values ​​of the connected and cut optical fiber signals through the set reference value. When the optical fiber signal is inconsistent with the reference value, it can be analyzed that the transported cigarette pack is inverted, and then the specific position of the cigarette pack is located by the speed ratio of the conveying channel, and the inverted cigarette pack can be corrected.

[0027] A limit plate 19 is fixedly mounted on the lower end of a tension strut 18 on one side of the swinging light baffle 16. This limit plate 19 is made of 45# steel and is screwed to the top plate 1 at its upper end. The limit plate 19 is positioned on the side corresponding to the direction of motion of the swinging light baffle 16 and limits its maximum range of motion. This means that the swinging light baffle 16 comes into contact with the limit plate during its swinging motion. The limit plate is made of a flexible sheet material and has a slotted horizontal portion at its lower end, which secures it to the lower end of the tension strut. This slot allows the position of the limit plate to be adjusted, thereby adjusting the maximum swing amplitude of the swinging light baffle.

[0028] like Figure 4As shown, the base plate of the irregular cigarette pack inversion detection device has two parallel elongated holes, through which it is mounted on a plexiglass plate 20. The mounting position of the device can be adjusted. The plexiglass plate 20 is mounted above a conveyor belt 21, forming a conveying channel between the plexiglass plate 20 and the conveyor belt 21. This channel ensures the proper transport of the U-shaped notched cigarette packs 11. The plexiglass plate 20 has mounting holes for the device, which are bolted to the base plate. A detection window is defined at the lower end of the plexiglass plate 20, where the device is mounted. The detection window is larger than the detection opening 15.

[0029] like Figures 5 to 7 As shown, when in use, this device is fixed above the plexiglass plate on the conveyor belt. The device is adjusted to optimal operation using the stop and adjustment nuts. The detection rod ensures that it can contact the cigarette pack through the detection window. The top of the cigarette pack is open, with a "U"-shaped notch on the front to reveal the filter surface. The conveyor belt drives the cigarette pack within the conveyor channel. When the cigarette pack moves to the lower end of the detection rod through the conveyor belt, the "U"-shaped notch of the cigarette pack and the detection rod do not rub against each other, the swinging light baffle on the detection rod does not move, and the swinging light baffle blocks the optical fiber signal of the optical fiber head; when the "U"-shaped notch on the cigarette pack has completed its movement from the lower end of the detection rod, the surface of the cigarette pack and the detection rod rub against each other, driving the detection rod to deviate along the movement direction of the cigarette pack, and the detection rod drives the rocker arm to deviate along the bracket adjustment rod, and the rocker arm drives the swinging light baffle to deviate in the opposite direction of the cigarette pack, and after the swinging light baffle deviates, the optical fiber heads on the inner and outer plates are connected to the optical fiber signal, and the limit plate collides with the swinging light baffle, and the limit plate gives a reaction force to the swinging light baffle, and the swinging light baffle gives a reaction force to the detection rod, and the detection rod continues to rub against the cigarette pack until the entire cigarette pack is detected. When the next cigarette pack is inspected, the U-shaped notch in the pack does not rub against the probe rod. Gravity forces the probe rod to swing and deflect along the bracket's adjustment rod, which then drives the swinging light shield to move in response to the probe rod's deflection. The swinging light shield blocks the fiber optic heads on the inner and outer panels, cutting off the signal until the pack reaches the surface of the cigarette pack, where it continues to rub against the probe. Because the length of the cigarette pack is fixed, and the length of the U-shaped notch is also fixed, after collecting the fiber optic signal from the fiber optic head, data analysis is used to determine whether the cigarette pack is correctly oriented. When the fiber optic signal value collected when the cigarette pack is inverted differs from the reference value, comparison can be used to determine that the pack is inverted in the channel, allowing appropriate action to be taken.
