Description

Technical Field

[0001] This utility model relates to the field of packaging bottle production, and in particular to a device for detecting misaligned bottles. Background Technology

[0002] In the modern packaging industry, packaging bottles are widely used, covering many fields such as food, beverages, cosmetics, and pharmaceuticals. Packaging bottles must not only ensure the sealing and stability of the product, but also maintain a standardized appearance. With the diversification of market demands, the variety of packaging bottles is increasing, with different bottle shapes, sizes, and materials being widely used. For example, in the beverage industry, plastic bottles and glass bottles are common, with shapes including round, square, and irregular shapes. In the cosmetics and pharmaceutical industries, packaging bottles made of special materials and designs are also used. This diversity presents significant challenges to packaging production equipment, especially in the bottle conveying and inspection stages.

[0003] Currently, on wet filling machine production lines, PAA (Patent Acid) plus process water is typically used to sterilize the inside and outside of bottles to ensure product hygiene and safety. However, these machines often use an air conveyor belt for bottle feeding. Because the equipment needs to produce various bottle types, some bottles may become skewed during clamping in the feeding area. This skewness may be due to vibration or collision during the conveying process.

[0004] Traditional packaging bottle inspection technologies have many shortcomings; some simple inspection methods rely solely on manual visual observation, which is not only inefficient but also prone to missed detections and misjudgments, failing to meet the needs of large-scale production; while some automated inspection equipment can only inspect specific bottle types and has poor adaptability to multiple bottle types; when some bottles are tilted in the inlet area, traditional inspection technologies struggle to identify them in a timely and accurate manner.

[0005] Tilted bottles entering subsequent transfer processes can cause a series of problems. For example, during transfer, tilted bottles may collide with other components, causing damage and affecting product quality and production efficiency. In addition, tilted bottles may also affect subsequent filling and labeling processes, leading to inaccurate filling, uneven labeling, and other problems, increasing production costs and defect rates. Utility Model Content

[0006] To address the problem of bottles easily becoming misaligned during the clamping and sterilization process in existing technologies, this utility model provides a misaligned bottle detection device.

[0007] The present invention provides a device for detecting misaligned bottles, which adopts the following technical solution:

[0008] A bottle tilting detection device includes a transfer clamp, a rotating star wheel, and a central shaft. The rotating star wheel is fixedly connected to the top of the central shaft. Several transfer clamps for transferring and fixing bottles are fixed to the outer wall of the rotating star wheel by bolts. A base plate is mounted on the outer wall of the central shaft by a fixing device. A base is bolted to the top of the base plate. A fixed bracket is rotatably connected to the base plate. A baffle is bolted to the inside of the fixed bracket. The top of the baffle has a detection groove that allows bottles in a vertical position to pass through. A sensor bracket is bolted to the top of the base plate. A sensor for detecting the rotation state of the baffle is installed inside the sensor bracket.

[0009] Furthermore, the base has a "U" shaped structure; the bottom of the fixed bracket is integrally formed with a rotating part that is rotatably connected to the base; the fixed bracket is integrally formed with an L-shaped detection part on the side near the sensor. When the detection part is removed from the recognition range of the sensor due to the rotation of the baffle, the currently detected bottle is in a tilted state.

[0010] Furthermore, the outer side wall of the fixed bracket is integrally formed with a limiting part; the top of the base is integrally formed with a positioning part; a tension spring is fixed between the fixed bracket and the base plate by bolts, and the tension spring is used to pull the fixed bracket so that the limiting part contacts the positioning part, at which time the baffle is in a vertical state.

[0011] Furthermore, the transfer clamps are evenly distributed along the circumference of the rotating star wheel, and the spacing between adjacent transfer clamps is equal.

[0012] Furthermore, the shape of the detection groove is adapted to the outer diameter of the bottle in a vertical position, and the width of the detection groove is 1-10 mm greater than the outer diameter of the bottle.

[0013] Furthermore, the sensor is a proximity sensor or a photoelectric sensor.

[0014] Furthermore, the fixing device is a clamp, which is tightly fixed to the outer side wall of the central shaft, and the base plate is fixedly connected to the outside of the clamp.

[0015] Furthermore, the baffle is made of polyurethane or metal, and the edge of the detection groove has a rounded transition.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] This invention achieves stable bottle transfer through a rotating star wheel and a transfer clamp. Utilizing a baffle with a detection groove and a sensor, it can accurately detect skewed bottles. Regardless of the bottle's shape, if a bottle is skewed, it will interfere with the baffle, causing the baffle to rotate. Once the sensor detects the change in the baffle's rotation, it can determine that the bottle is skewed. This detection method is not limited by bottle type, has high versatility and accuracy, effectively prevents skewed bottles from entering subsequent processes, reduces equipment failures, and improves production efficiency and product quality.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail below:

[0025] This utility model discloses a device for detecting misaligned bottles, such as... Figure 1-5As shown, a bottle tilting detection device includes a transfer clamp 1, a rotating star wheel 6, and a central shaft 7. The rotating star wheel 6 is fixedly connected to the top of the central shaft 7. Several transfer clamps 1 for transferring and fixing bottles 2 are fixed to the outer wall of the rotating star wheel 6 by bolts. A base plate 11 is installed on the outer wall of the central shaft 7 by a fixing device 8. A base 10 is installed on the top of the base plate 11 by bolts. A fixed bracket 9 is rotatably connected inside the base 10. A baffle 3 is installed inside the fixed bracket 9 by bolts. The top of the baffle 3 has a detection groove 31 that allows bottles 2 in a vertical state to pass through. A sensor bracket 4 is installed on the top of the base plate 11 by bolts. A sensor 5 for detecting the rotation state of the baffle 3 is installed inside the sensor bracket 4. In this embodiment, the detection groove 31 on the baffle 3 is used to allow the vertically positioned bottle 2 to pass through. When the bottle 2 is tilted, it will interfere with the baffle 3, causing the baffle 3 to rotate. The sensor 5 is used to detect the rotation state of the baffle 3 to determine whether the bottle 2 is tilted. The rotating star wheel 6 drives the transfer clamp 1 to rotate, and the transfer clamp 1 holds the bottle 2 and moves it towards the baffle 3. The bottle 2 enters the detection groove 31 of the baffle 3. If the bottle 2 is vertical, it will pass through the detection groove 31 smoothly, and the baffle 3 remains stationary. If the bottle 2 is tilted, it will collide with the edge of the detection groove 31, pushing the baffle 3 to rotate. The sensor 5 detects the change in the rotation state of the baffle 3 and sends a corresponding signal. The transfer of the bottle 2 is achieved by rotating the star wheel 6 and transferring the clamp 1. By using the cooperation of the baffle 3 and the sensor 5, tilted bottles 2 can be effectively detected, preventing tilted bottles 2 from entering subsequent processes and reducing equipment failures.

[0026] like Figure 1-5 As shown, the base 10 has a U-shaped structure; the bottom of the fixed bracket 9 is integrally formed with a rotating part 93 that is rotatably connected to the base 10; the side of the fixed bracket 9 closest to the sensor 5 is integrally formed with an L-shaped detection part 91. When the detection part 91 moves out of the recognition range of the sensor 5 due to the rotation of the baffle 3, the currently detected bottle 2 is in a tilted state. In this embodiment, under normal circumstances, the detection part 91 is within the recognition range of the sensor 5, and the sensor 5 maintains a stable state; when the tilted bottle 2 collides with the baffle 3, the baffle 3 drives the fixed bracket 9 to rotate, and the detection part 91 moves out of the recognition range of the sensor 5 as the fixed bracket 9 rotates; the sensor 5 detects the change in the position of the detection part 91 and outputs a corresponding signal, indicating that the currently detected bottle 2 is tilted; the design of the U-shaped base 10 and the rotating part 93 ensures the stability and flexibility of the rotation of the fixed bracket 9, and the cooperation of the L-shaped detection part 91 and the sensor 5 can accurately detect the rotation state of the baffle 3, thereby achieving accurate detection of tilted bottles.

[0027] like Figure 1-5As shown, the outer side wall of the fixed bracket 9 is integrally formed with a limiting part 92; the top of the base 10 is integrally formed with a positioning part 101; a tension spring 12 is fixed between the fixed bracket 9 and the base plate 11 by bolts. The tension spring 12 is used to pull the fixed bracket 9 so that the limiting part 92 contacts the positioning part 101, at which time the baffle 3 is in a vertical state. In this embodiment, in the initial state, the tension spring 12 pulls the fixed bracket 9, causing the limiting part 92 to contact the positioning part 101, and the baffle 3 is in a vertical state. When the tilted bottle 2 collides with the baffle 3, the force of the bottle 2 on the baffle 3 overcomes the tension of the tension spring 12, causing the fixed bracket 9 to rotate, and the limiting part 92 to separate from the positioning part 101. After the bottle 2 passes through, the tension of the tension spring 12 will cause the fixed bracket 9 to return to the initial position, the limiting part 92 to contact the positioning part 101 again, and the baffle 3 returns to a vertical state. The cooperation of the limiting part 92, the positioning part 101, and the tension spring 12 ensures the vertical state of the baffle 3 under normal conditions, and can automatically return to the initial position after the bottle 2 passes through, preparing for the next detection, thus improving the stability and reliability of the detection device.

[0028] like Figure 1-5 As shown, the transfer clamps 1 are evenly distributed along the circumference of the rotating star wheel 6, and the spacing between adjacent transfer clamps 1 is equal. In this embodiment, when the rotating star wheel 6 rotates, the transfer clamps 1 rotate together with the rotating star wheel 6, and each transfer clamp 1 sequentially reaches the bottle inlet position and clamps the bottle 2; after being clamped by the transfer clamps 1, the bottle 2 moves towards the baffle 3 as the rotating star wheel 6 rotates; the bottle 2 enters the detection groove 31 of the baffle 3. If the bottle 2 is in a vertical state, it will pass smoothly through the detection groove 31, and the baffle 3 remains stationary; if the bottle 2 is in a tilted state, the bottle 2 will collide with the edge of the detection groove 31, pushing the baffle 3 to rotate; the sensor 5 detects the change in the rotation state of the baffle 3 and sends out a corresponding signal.

[0029] like Figure 1-5 As shown, the shape of the detection groove 31 is adapted to the outer diameter of the bottle 2 in a vertical state, and the width of the detection groove 31 is 1-10 mm greater than the outer diameter of the bottle 2. In this embodiment, when the vertical bottle 2 enters the detection groove 31, the bottle 2 can pass through easily without interfering with the edge of the detection groove 31 because the width of the detection groove 31 is appropriate; when the tilted bottle 2 enters the detection groove 31, the tilted part of the bottle 2 will contact the edge of the detection groove 31, generating a lateral force that pushes the baffle 3 to rotate; the appropriate shape and width design of the detection groove 31 can accurately distinguish between vertical bottles 2 and tilted bottles 2, improving the accuracy of tilted bottle detection.

[0030] like Figure 1-5As shown, sensor 5 is a proximity sensor or a photoelectric sensor. In this embodiment, both the proximity sensor and the photoelectric sensor have the characteristics of non-contact detection, which can quickly and accurately detect changes in the position of an object. In this device, sensor 5 is used to detect changes in the position of the detection part 91 on the fixed bracket 9. When the detection part 91 enters or leaves the detection range of sensor 5, sensor 5 will output a corresponding electrical signal to determine whether the baffle 3 is rotating, and thus determine whether the bottle 2 is tilted.

[0031] like Figure 1-5 As shown, the fixing device 8 is a clamp, which is tightly fixed to the outer wall of the central shaft 7, and the base plate 11 is fixedly connected to the outer side of the clamp. In this embodiment, the clamp is fitted onto the central shaft 7, and the clamp is tightened by tightening the bolts of the clamp to make the clamp hold the central shaft 7 tightly; the base plate 11 is fixed to the outer side of the clamp, completing the installation of the base plate 11; during the operation of the equipment, the clamp and the base plate 11 remain relatively stationary together with the central shaft 7, providing a stable mounting base for the detection components; the use of the clamp facilitates the installation and removal of the base plate 11, and can provide a reliable fixing effect, ensuring the stability and reliability of the entire detection device.

[0032] like Figure 1-5 As shown, the baffle 3 is made of polyurethane or metal, and the edge of the detection groove 31 has a rounded transition. In this embodiment, the polyurethane or metal baffle 3 has high wear resistance and strength, and can withstand the collision and friction between the bottle 2 and the baffle 3, extending the service life of the baffle 3. The rounded transition design of the edge of the detection groove 31 can prevent the bottle 2 from being scratched by the sharp edge when passing through the detection groove 31, and at the same time make the collision between the bottle 2 and the baffle 3 smoother, reducing damage to the bottle 2 and the baffle 3. The wear-resistant material of the baffle 3 and the rounded transition design improve the service life of the baffle 3, reduce damage to the bottle 2, and ensure the long-term stable operation of the detection device.
