Description

Technical Field

[0001] This utility model belongs to the field of labeling machine or sorting machine application technology, specifically relating to a gate-type sensing device suitable for infusion bags. Background Technology

[0002] Currently, the detection of transparent soft bags or stand-up pouches is generally carried out through photoelectric sensors or visual image detection.

[0003] Because transparent soft bags or stand-up pouches are irregularly shaped, contain transparent liquid, and are prone to movement, photoelectric sensors are susceptible to unstable detection times and failure to detect them. As for visual image detection solutions, the material and smoothness of transparent soft bags and stand-up pouches cause varying degrees of light reflection and transmission, making image recognition more challenging. Illumination angle and uniformity are crucial considerations. To ensure the camera captures clearer and more complete images, the required space is generally larger, resulting in higher overall costs. Furthermore, the influence of airborne impurities and large particles must also be taken into account.

[0004] In summary, current methods for detecting transparent soft bags or stand-up pouches either produce unstable test results or occupy a large amount of space, resulting in high actual costs and difficulties in application.

[0005] To address the aforementioned problems, this invention provides a gate-type sensing device suitable for infusion bags. Utility Model Content

[0029] In addition, the gate-type sensing device preferably applicable to infusion bags also includes a bulletproof plate 5 disposed on one side surface of the swing plate 4, and a set of bulletproof plate shaft holes 5 disposed on one end face of the bulletproof plate 5; wherein, the bulletproof plate 5 is mounted on the swing plate fixing plate 2 by means of a pin 9 through a set of bulletproof plate shaft holes 50.

[0032] The working principle or structural principle of the gate-type sensing device suitable for infusion bags in this structure is as follows:

[0033] The detection device is used on production lines or belt conveyors for transparent soft bags and stand-up pouches, enabling precise detection of the position of transparent soft bags and stand-up pouches.

[0034] The detection device can be placed above the conveyor belt through which transparent soft bags or stand-up pouches pass. When the transparent soft bag or stand-up pouch reaches the detection position, it contacts the swing plate 4, lifting the swing plate 4. After the swing plate 4 is raised to a certain angle, the upper sensing protrusion 41 triggers the grooved photoelectric sensor 8. The photoelectric signal is transmitted to the remote control system (not shown in the figure, but it does not affect the disclosure of the technical solution of this application) to confirm that the transparent soft bag or stand-up pouch has reached the inspection position. The transparent soft bag or stand-up pouch continues to move forward, and the grooved photoelectric sensor 8 is continuously triggered and the signal is continuously output. When the transparent soft bag or stand-up pouch has completely passed the detection position, the swing plate 4 begins to return to the anti-collision plate 6, the signal of the grooved photoelectric sensor 8 is disconnected, the bulletproof plate 5 is raised, and the swing plate 4 no longer bounces under the tension of the upper tension spring 10 and the action of the bulletproof plate 5. The single detection ends, and the device waits for the next product to be detected.
