Description

Technical Field

[0001] This application relates to the technical field of cigarette hard box packaging equipment, and in particular to a device for detecting misalignment of the stamped part of the small box for the FOCKE350 packaging machine. Background Technology

[0002] The FOCKE350S unit is currently a mainstream medium-speed cigarette hard pack packaging equipment. The unit consists of four parts: a small pack packaging machine, an automatic cigarette storage cabinet, a small package transparent paper packaging machine, and a carton transparent paper packaging machine. In the FOCKE350 small pack packaging process, the label paper is the outer packaging carrier of the small pack, while the steel stamp is a permanent mark pressed onto the label paper by a steel stamping roller, containing production information.

[0003] The working principle of the label paper conveying and printing is as follows: the small box label paper is picked up by the pick-up drum of the crank slider mechanism and conveyed to the conveyor roller. It is then conveyed down to the space between the steel stamp and the steel stamp pad roller to complete the steel stamp printing of the small box label paper. Then it continues to be conveyed down to the glue conveyor roller until the glue application and pre-folding processes of the small box label paper are completed.

[0004] During the printing process, technicians discovered that the label paper on the small boxes was misaligned. The traditional method to address this issue is to manually inspect the position of the embossed logo on the bottom of the cigarette pack. Only if it meets the relevant requirements will the pack proceed to the next packaging stage. However, manual inspection relies on experience and is prone to omissions, resulting in defective products being released. Utility Model Content

[0005] This application provides a device for detecting misalignment of stamped steel marks on small boxes for the FOCKE350 packaging machine, which aims to solve the problem that manual detection of stamp misalignment can easily lead to the outflow of unqualified products.

[0006] In one embodiment, a device for detecting misalignment of stamped labels on small boxes is provided for a FOCKE350 packaging machine. This device includes an encoder, a small box label, a conveyor roller, a stamping roller, a stamping pad roller, and a guide plate. It also includes:

[0007] A detection plate positioned above the label on the small box;

[0008] A mounting groove is formed along the length of the detection plate;

[0009] The mounting groove has a first sensor at the end closest to the stamping roller, and three second sensors arranged along its length at the end furthest from the stamping roller.

[0010] In one embodiment, the detection plate is fixed to the mounting plate of the FOCKE350 by bolts, and the first sensor and the second sensor are installed in the mounting groove by fastening bolts.

[0011] In one embodiment, the detection plate is fixed to the mounting plate of the FOCKE350 via an adjustment mechanism, the adjustment mechanism comprising:

[0012] A rectangular base is provided at the lower end of the mounting plate. A ball groove is provided in the middle of the rectangular base. A ball is rotatably connected in the ball groove. A connecting rod is inserted into the ball. The end of the connecting rod away from the ball is connected to the detection plate.

[0013] In one embodiment, the sphere is provided with a limiting sleeve around its circumference, a first connecting plate is provided on one radial side of the limiting sleeve, hinge plates are provided on both radial sides of the first connecting plate, a rotating shaft is passed through the hinge plate, and the rotating shaft is connected to the first connecting plate.

[0014] In one embodiment, a second connecting plate is provided on the other radial side of the limiting sleeve. The second connecting plate and the rectangular seat are respectively provided with screw holes along their respective height directions, and bolts are threaded into the screw holes.

[0015] In one embodiment, a telescopic rod is provided between the rectangular base and the mounting plate. The movable end of the telescopic rod is connected to the end of the rectangular base away from the detection plate, and the other end is fixed to the end of the mounting plate near the rectangular base.

[0016] In one embodiment, the telescopic rods are provided in two and distributed along the diagonal of the rectangular base.

[0017] The beneficial effects of this application are as follows: The detection device, consisting of a detection plate, a mounting groove, a first sensor, and a second sensor, automatically detects the position of the label paper on the small box, thereby facilitating the timely removal of misaligned label paper. By replacing manual experience-based judgment with an objective and quantified signal combination, the detection accuracy is improved, thus avoiding the problem of missed detections and defective products being released due to reliance on experience in manual detection.

[0032] This application proposes improvements and innovations, and presents the following embodiments.

[0033] Example 1:

[0034] See Figure 1 and Figure 2 In one embodiment, a device for detecting misalignment of stamped labels on small boxes for a FOCKE350 packaging machine is provided, comprising an encoder, a small box label 1, a conveyor roller 2, a stamping roller 3, a stamping pad roller 4, and a guide plate 5, and further comprising:

[0035] The detection plate 6 is located above the label paper 1 of the small box;

[0036] A mounting groove 7 is formed along the length of the detection plate 6;

[0037] The mounting groove 7 is provided with a first sensor 8 at one end near the steel printing roller 3, and three second sensors 9 are arranged along its length at the other end of the mounting groove 7 away from the steel printing roller 3.

[0038] Specifically, the encoder, small box label 1, conveyor roller 2, stamping roller 3, stamping pad roller 4, and guide plate 5 are all components of the FOCK E350S packaging machine. The small box label 1 is placed on the guide plate 5 and conveyed by the conveyor roller 2 to the stamping roller 3 and stamping pad roller 4 for stamping. Both the first sensor 8 and the second sensor 9 are fiber optic sensors. The fiber optic sensors are connected to the controller via amplifiers. The controller reads the encoder signal of the FOCK E350S packaging machine. When the stamping pad roller 4 and stamping roller 3 are directly facing the label, the controller performs logical judgment on the signals from the four amplifiers:

[0039] When the signal from the first sensor 8 near the stamping roller 3 is high, if the signals from the three second sensors 9 are all high or all low, the position of the small box label 1 is severely misaligned. The controller counts based on the encoder signal, and when the cigarette pack is about to enter the rejection port of the FOCKE350S packaging machine, it sends a rejection valve signal to reject it. When the signal near the stamping roller 3 is low, and more than one of the three signals is high, it indicates that the conveyor channel is blocked by the small box label 1. This signal is merged into the conveyor channel blockage signal cutoff, thereby triggering the shutdown procedure. Through the above operations, the misaligned small box label 1 is rejected, preventing it from flowing out.

[0040] In this application, a detection device consisting of a detection plate 6, a mounting groove 7, a first sensor 8, and a second sensor 9 automatically detects the position of the small box label paper 1, thereby facilitating the timely removal of small box label papers 1 that are out of position. By replacing manual experience judgment with an objective and quantitative signal combination, the detection accuracy is improved, thereby avoiding the problem that manual detection relies on experience and is prone to missed detection, resulting in the outflow of unqualified products.

[0041] It should be noted that the first sensor 8 was not in Figure 2 As shown in the image.

[0042] Example 2:

[0043] See Figure 1 and Figure 2 Based on Embodiment 1, in one scheme, the detection plate 6 is fixed to the mounting plate 21 of the FOCKE350 by bolts 19 (not shown in the figure), and the first sensor 8 and the second sensor 9 are installed in the mounting groove 7 by fastening bolts 19.

[0044] Specifically, the detection plate 6 is fixed to the mounting plate 21 by bolts 19, which achieves rigid positioning of the detection plate 6 and prevents it from shifting due to vibration during machine operation. This ensures that the relative positions of the mounting groove 7 and the sensors within the groove with components such as the small box label paper 1 and the steel stamping roller 3 always conform to the preset detection angle. The first sensor 8 and the second sensor 9 are installed in the mounting groove 7 by fastening bolts 19. On the one hand, the groove provides initial limiting guidance for the sensors, ensuring their accurate arrangement along the length of the groove. On the other hand, the bolts 19 eliminate gaps, preventing the sensors from loosening or shifting due to equipment vibration during detection. This ensures that each sensor can stably align with the preset detection area of ​​the small box label paper 1, thereby ensuring the consistency and reliability of the output signal. This provides accurate raw data for the controller's logical judgment (such as the signal combination recognition of whether the label paper is misaligned), ultimately achieving accurate detection and rejection of misaligned label paper. In addition, the bolt 19 connection method also facilitates the disassembly and replacement of the connecting components.

[0045] Example 3:

[0046] See Figures 3 to 5 Based on the above embodiments, in one solution, the detection plate 6 is fixed to the mounting plate 21 of the FOCKE350 by an adjustment mechanism, the adjustment mechanism comprising:

[0047] A rectangular base 10 is provided at the lower end of the mounting plate 21. A ball groove 11 is provided in the middle of the rectangular base 10. A ball 12 is rotatably connected in the ball groove 11. A connecting rod 13 is inserted into the ball 12. The end of the connecting rod 13 away from the ball 12 is connected to the detection plate 6.

[0048] Specifically, part of the sphere 12 is nested within and rotatably connected to the sphere groove 11, enabling the sphere 12 to rotate at multiple angles. A connecting rod 13 is inserted, threaded, or fixedly connected to the sphere 12. The end of the connecting rod 13 away from the sphere 12 is connected to the detection plate 6. In this way, the rotation of the sphere 12 can drive the detection plate 6 to rotate synchronously, allowing the first sensor 8 and the second sensor 9 installed in the mounting groove 7 to be flexibly adjusted at multiple angles. This ensures that the sensors are always aligned with the preset detection area of ​​the label paper, compensating for the impact of installation errors or minor positional shifts during equipment operation on detection accuracy.

[0049] In one embodiment, the sphere 12 is circumferentially fitted with a limiting sleeve 14. A first connecting plate 15 is provided on one radial side of the limiting sleeve 14, and hinge plates 16 are provided on both radial sides of the first connecting plate 15. A rotating shaft 17 passes through the hinge plate 16 and is connected to the first connecting plate 15. A second connecting plate 18 is provided on the other radial side of the limiting sleeve 14. The second connecting plate 18 and the rectangular base 10 are respectively provided with threaded holes along their respective height directions, and bolts 19 are threaded into these holes.

[0050] Specifically, the first connecting plate 15 of the sphere 12 is hinged to the hinge plate 16 of the rectangular seat 10 via a rotating shaft 17. The second connecting plate 18 of the sphere 12 is fastened to the rectangular seat 10 via bolts 19. The axial force of the bolts 19 pulls the second connecting plate 18 towards the rectangular seat 10. Since the first connecting plate 15 is hinged to the hinge plate 16 of the rectangular seat 10 via the rotating shaft 17, the entire limiting sleeve 14 will rotate around the rotating shaft 17 towards the sphere 12, applying a radial clamping force to the sphere 12. This radial force eliminates the gap between the limiting sleeve 14 and the sphere 12, forming an interference fit, thereby restricting the rotation of the sphere 12 within the ball groove 11, thus fixing the orientation of the connecting rod 13. When adjusting the orientation of the connecting rod 13, the rotatable bolt 19 can be rotated to loosen the fastening of the second connecting plate 18 to the rectangular seat 10, and then the orientation of the connecting rod 13 can be adjusted to the set position and the bolt 19 tightened, thereby fixing the orientation of the connecting rod 13 again. In this way, the angle adjustment of the first sensor 8 and the second sensor 9 is achieved.

[0051] In one embodiment, a telescopic rod 20 is provided between the rectangular base 10 and the mounting plate 21. The movable end of the telescopic rod 20 is connected to the end of the rectangular base 10 away from the detection plate 6, and the other end is fixed to the end of the mounting plate 21 near the rectangular base 10.

[0052] Specifically, the detection distance of fiber optic sensors typically needs to be controlled between 5-20mm. When the detection distance is less than 5mm, the object is too close, resulting in excessively high reflected light intensity, exceeding the linear response range of the sensor's receiver. At this distance, the rate of change in light intensity is extremely low, making it impossible to accurately distinguish minute object displacements based on intensity differences, leading to decreased detection accuracy. When the detection distance is greater than 20mm, the light beam attenuates due to diffusion and air scattering during propagation, causing a sharp decrease in reflected light intensity. If the light intensity is below the sensor's sensitivity threshold, missed detections may occur; simultaneously, minute fluctuations in light intensity with distance are amplified, resulting in poor signal stability.

[0053] In this embodiment, the distance between the rectangular base 10 and the mounting plate 21 can be finely adjusted by the telescopic characteristics of the telescopic rod 20. Combined with the angle adjustment achieved by the rotation of the ball 12, a multi-dimensional adjustment mechanism of angle and distance is formed. This ensures that the sensor on the detection plate 6 and the small box label 1 maintain the optimal detection distance, avoiding signal sensitivity issues caused by excessively close or far distances. Optionally, the telescopic rod 20 can be a small or micro electric telescopic rod 20.

[0054] In one embodiment, the telescopic rods 20 are provided in two and distributed along the diagonal of the rectangular base 10.

[0055] Specifically, the telescopic rods 20 are provided in two and distributed along the diagonal of the rectangular base 10 to form a diagonal support structure. Compared with parallel distribution, this can more evenly distribute the self-weight and vibration load of the rectangular base 10 and avoid deformation caused by force concentration during adjustment. At the same time, the two telescopic rods 20 set diagonally can also avoid the problems of easy instability of a single telescopic rod 20 and increased control difficulty and decreased control accuracy caused by multiple telescopic rods 20.

[0056] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model.
