Description

Technical Field

[0001] This utility model relates to the field of cosmetic filling equipment technology, and in particular to an empty bottle detection alarm device suitable for cosmetic filling. Background Technology

[0002] In automated cosmetic production lines, filling is a crucial step. To ensure filling quality and efficiency, detection devices are typically installed before the filling station to determine whether the bottles on the conveyor belt are empty, thus preventing refilling of bottles already filled with liquid or the loss of empty bottles.

[0003] The aforementioned detection functions are typically achieved using optical sensors such as reflective fiber optic sensors, which need to be precisely fixed to the production line using brackets. However, the cosmetics industry experiences rapid product line changes, with a wide variety of bottle shapes and sizes, as well as differences in bottle materials and transparency.

[0004] When changing to cosmetic bottles of different sizes, the sensor's beam often needs to be fine-tuned to ensure it accurately illuminates the optimal detection location on the bottle (e.g., the neck or bottom). Existing sensor holders typically use bolts for angle adjustment. Operators must first loosen the bolts using a wrench or screwdriver, then rely on feel and experience to rotate the holder to the approximate position before tightening the bolts again.

[0005] This adjustment method has significant drawbacks. First, the adjustment process relies on tools, which is not only cumbersome but also inefficient in production environments with frequent line changes, increasing downtime for equipment debugging. Second, manual support results in poor angle positioning accuracy, is prone to displacement during locking, and makes it difficult to achieve precise angle reversal. Improper adjustment can lead to unstable detection signals, affecting the accuracy and reliability of empty bottle detection.

[0006] Therefore, this utility model proposes an empty bottle detection alarm device suitable for cosmetic filling to overcome the shortcomings of the prior art. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 4 This utility model provides an empty bottle detection alarm device suitable for cosmetic filling, which aims to solve the problems of inconvenient angle adjustment and unreliable positioning of existing sensor brackets.

[0026] The empty bottle detection alarm device for cosmetic filling includes a mounting frame 1 and an adjustment mechanism 6 for adjusting and locking the angle of the mounting frame 1. The mounting frame 1 is used to mount a reflective fiber optic sensor 2 and a liquid detection sensor 3. The adjustment mechanism 6 serves as the basic frame of the entire device and includes a mounting plate 601 as a base. A limit rod 603 is vertically fixed on the mounting plate 601, and the mounting frame 1 is movably mounted on the adjustment mechanism 6 by being rotatably and axially slidingly sleeved on the outer periphery of the limit rod 603. To limit the axial position of the mounting frame 1, a limit block 604 is fixedly connected to the upper end of the limit rod 603, and a third spring 605 is sleeved on the limit rod 603 and located between the limit block 604 and the bottom of the mounting frame 1. The mounting bracket 1 is held upwards. To lock the angle of the mounting bracket 1, the adjustment mechanism 6 also includes a grooved ring 602 fixed on the mounting plate 601 and coaxially surrounding the mounting bracket 1, and a positioning rod 606 fixed on the outer wall of the mounting bracket 1. In its natural state, the rebound force of the third spring 605 allows the positioning rod 606 to be plugged into the groove on the grooved ring 602. When the angle needs to be adjusted, the mounting bracket 1 is lifted by applying an external force, which compresses the third spring 605 and causes the positioning rod 606 to disengage from the groove. At this time, the mounting bracket 1 can be rotated. After being rotated to the predetermined angle, it is released, the third spring 605 rebounds and resets, pushing the positioning rod 606 into the corresponding groove, thereby fixing the angle of the mounting bracket 1.

[0027] The mounting bracket 1 has multiple positioning holes 506. The positioning mechanism 5 includes a second connecting shell 501 slidably mounted on the mounting bracket 1. A pin 502 is provided on the inner side of the second connecting shell 501. The pin 502 is pluggably engaged with the positioning holes 506 on the mounting bracket 1. By selectively inserting the pin 502 into different positioning holes 506, the height position of the second connecting shell 501 on the mounting bracket 1 can be fixed. To drive the pin 502 to perform insertion and removal movements, the positioning mechanism 5 also includes a U-shaped rod 503, a second spring 504, and a limit cap 505. The U-shaped rod 503 and the second connecting shell 501 are integrally set, so that they can be used to drive the pin 502 to move synchronously. The limit cap 505 is fixed to one end of the U-shaped rod 503. When the height needs to be adjusted, pulling the U-shaped rod 503 will drive the pin 502 to disengage from the positioning hole 506. At this time, the second connecting shell 501 can slide on the mounting bracket 1. After adjusting to a suitable height, the U-shaped rod 503 is released. Under the elastic force of the second spring 504, the pin 502 will automatically reset and insert into the new positioning hole 506. This structure ensures the convenience of height adjustment and the reliability of positioning.

[0028] The quick-installation mechanism 4 includes a first connecting shell 401 that abuts against the second connecting shell 501, and a U-shaped rod 503 that passes through the first connecting shell 401. The two ends of the second spring 504 abut against the limit cap 505 and the inner wall of the first connecting shell 401, respectively. With this arrangement, the quick-installation mechanism 4 and the positioning mechanism 5 are integrated into one unit. To achieve the clamping function, the quick-release mechanism 4 includes a first locking block 402 integrated with the first connecting shell 401, a screw 405 and a second locking block 404. The screw 405 passes through the first locking block 402, and the second locking block 404 passes through the outside of the screw 405, forming a fixed first locking block 402 and a movable second locking block 404. To drive the second locking block 404 to move, the quick-release mechanism 4 further includes a cam handle 406 rotatably disposed at one end of the screw 405, and a first spring 403 disposed between the first connecting shell 401 and the second locking block 404. When the cam handle 406 is turned, it will abut against the second locking block 404 and squeeze the first spring 403 to push the second locking block 404 toward the first locking block 402. Preferably, a nut 407 is screwed onto the other end of the screw 405 to fasten the axial components of the entire quick-release mechanism 4. Finally, the reflective fiber optic sensor 2 and the liquid detection sensor 3 are clamped between the first card block 402 and the second card block 404.

[0029] Working principle: When the detection angle of the sensor needs to be adjusted, the operator pulls the mounting bracket 1 upward. The mounting bracket 1 will slide along the axial direction of the limiting rod 603 and compress the third spring 605 located between the limiting block 604 and the bottom of the mounting bracket 1. At the same time as the mounting bracket 1 moves upward, the positioning rod 606 fixed on the outer wall of the mounting bracket 1 will disengage from the groove of the groove ring 602. At this time, the mounting bracket 1 can be rotated to the new target angle. When the mounting bracket 1 is released, the elastic energy stored in the third spring 605 is released, pushing the mounting bracket 1 to reset and causing the positioning rod 606 to automatically engage in the groove corresponding to the new position, thus completing the rapid adjustment and reliable locking of the angle. When the installation height of the sensor needs to be adjusted, the operator pulls the U-shaped rod 503. Since the U-shaped rod 503 is integrated with the second connecting shell 501 and is used to drive the pin 502 to move, the pin 502 will be pulled out from the positioning hole 506 on the mounting bracket 1. At this time, the second connecting shell 501 and the quick-release mechanism 4 fixedly connected to the second connecting shell 501 can slide freely on the mounting bracket 1. After adjusting to the appropriate height, the U-shaped rod 503 is released. Under the elastic force of the second spring 504, the pin 502 will automatically insert into the nearest positioning hole 506 to complete the height setting. When it is necessary to install or replace the sensor, the operator turns the cam handle 406. The cam surface of the cam handle 406 will abut against the second locking block 404 and compress the first spring 403 located between the first connecting shell 401 and the second locking block 404, thereby pushing the second locking block 404 toward the first locking block 402, clamping the reflective fiber optic sensor 2 and the liquid detection sensor 3 between the first locking block 402 and the second locking block 404. Turning the cam handle 406 in the opposite direction will release the clamping under the rebound force of the first spring 403, realizing quick installation and removal. The nut 407 screwed on the other end of the screw 405 provides a stable preload force for the entire quick installation mechanism 4.
