Description

Technical Field

[0001] This utility model relates to the field of automated filling, specifically to an automated filling nozzle with a sensing function for hose installation. Background Technology

[0002] An automated filling line involves conveying several empty barrels on a production line, then filling them with liquid using nozzles, ultimately filling each empty barrel with liquid and achieving automated filling.

[0003] Within a certain timeframe, the specifications of the empty containers used in filling operations are generally consistent, so the length and diameter of the corresponding nozzles are also usually constant. After one batch of filling operations, the next batch of empty containers may have different dimensions, and the length and diameter of the corresponding nozzles may need to be replaced accordingly. In this case, the main body of the nozzle does not need to be replaced; only the type of tubing inserted into the empty container needs to be replaced. However, when manually replacing the tubing, there is a possibility that it may not be installed correctly or may be misaligned. If it is not installed correctly or with inaccurate precision, subsequent filling operations may be at risk. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an automated filling nozzle with sensing function for hose installation.

[0005] To solve the above problems, this utility model provides an automated filling nozzle with a sensing function for hose installation. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows:

[0006] An automated filling nozzle with a sensing function for hose installation includes: a linear drive cylinder that drives an output rod to move, the end of which is fitted with a plug; a three-way flange; a two-way pipe with its two ends communicating with each other; a hose detachably assembled with the two-way pipe; and a sensing mechanism including two sensors fixed to the outer wall of the two-way pipe, the sensors oriented radially inward, and the two sensors being oriented at an angle to each other; wherein the linear drive cylinder, the three-way flange, the two-way pipe, and the hose are arranged axially in sequence, and the sensors sense whether one end of the hose is properly assembled with one end of the two-way pipe.

[0007] As a further improvement of this utility model, a metal retaining ring is fixed to the outer wall of one end of the hose.

[0008] As a further improvement of this utility model, the sensor is a proximity switch, and the orientation of the sensor does not intersect with the two-way tube.

[0009] As a further improvement of this utility model, the outer wall of the two-way tube is assembled with the sensor by a fixing plate. The fixing plate has an oblong hole for assembling the sensor, and the length direction of the oblong hole is parallel to the axis of the two-way tube.

[0010] As a further improvement of this utility model, the sensor is connected to the linear drive cylinder via a signal. Only when both sensors are triggered will a trigger signal be sent to the linear drive cylinder to control the linear drive cylinder to perform a movement or stop action.

[0011] As a further improvement of this utility model, the outer wall of the two-way pipe is provided with an integral fixing seat, and the plane of the fixing seat is parallel to the axis of the two-way pipe.

[0012] As a further improvement of this utility model, the axial end of the hose away from the two-way tube has an end opening, the hose has a side opening connecting its inner wall and outer wall, the hose has an integrally radially extending branch tube, and the axial distance from the side opening to the end opening is shorter than the axial distance from the branch tube to the end opening.

[0013] As a further improvement of this utility model, the metal retaining ring is an aluminum open-type retaining ring, and the cross-sectional profile of the metal retaining ring at any point is rectangular.

[0014] As a further improvement of this utility model, the orientations of the two sensors are perpendicular to each other.

[0015] The beneficial technical effects of using the automated filling nozzle with hose installation sensing technology described in this application are:

[0016] By installing two sensors arranged radially inward at an angle on the outer wall of the two-way tube, the assembly status of the hose and the two-way tube can be accurately detected, effectively solving problems such as improper installation and skewed angles that easily occur when manually replacing the hose. This fundamentally eliminates potential hazards in subsequent filling operations caused by insufficient assembly precision, ensuring the assembly reliability of key components of the equipment before filling.

[0017] Because the skewed angle means there is a slight angle with the main axis, it means that after the hose is assembled, its shaft end is not horizontally aligned. There will be a situation where part is forward and part is backward. The part that is backward will be detected by the sensor, while the part that is forward will not be detected by the sensor.

[0018] If there is only a single sensor, and the plane formed by the skew direction of the hose and the main axis is perpendicular to the sensor's orientation, then even if the hose is skewed, the area directly illuminated by the sensor might appear to be perfectly aligned, which is not precise enough. Two sensors at an angle to each other, however, allow for accurate sensing of whether the hose is properly installed from different angles, facilitating mutual error correction and avoiding the limitations of sensing only one direction.

[0019] The structural design, in which the linear drive cylinder, three-way flange, two-way pipe, and hose are arranged axially, meets the fluid transport path requirements of automated filling. Replacing different hoses facilitates adaptation to different glue containers, such as hoses of different lengths. Attached Figure Description

The linear drive cylinder 1, three-way flange 2, two-way pipe 3, and hose 4 are arranged axially in sequence, and the sensors 6 sense whether one end of the hose 4 is properly assembled with one end of the two-way pipe 3.

[0031] The plug 9 can open or close one end of the tubing 4.

[0032] Additionally, since the length of hose 4 is variable, in order to facilitate the display of other components, Figure 1 , Figure 2 , Figure 4 The rubber tube 4 in the picture uses the natural fracture method.

[0033] The beneficial effects of adopting the above technical solution are as follows: setting two sensors 6 with their orientations at an angle to each other on the outer wall of the two-way pipe 3 can accurately detect the assembly status of the hose 4 from different angles, effectively solving the problem of improper installation or skewness that is easy to occur when replacing manually. At the same time, the axial arrangement of the linear drive cylinder 1, the three-way flange 2, the two-way pipe 3 and the hose 4 optimizes the fluid path, making it easy to quickly replace the hose 4 to adapt to different hose bucket specifications.

[0034] like Figure 3 As shown, in some other embodiments of this utility model, a metal retaining ring 5 is fixed to the outer wall of one end of the tubing 4.

[0035] The beneficial effects of adopting the above technical solution are: fixing a metal retaining ring 5 to the outer wall of one end of the tubing 4 provides a clear sensing reference for the sensor 6, enhances the stability and accuracy of the detection, and ensures the consistency of the assembly position of the tubing 4.

[0051] like Figure 3 As shown, the C-shaped metal retaining ring 5 forms a gap 501. The metal retaining ring 5 is threaded with a fastener 502. Tightening the fastener 502 can widen or narrow the gap 501.

[0052] The inner diameter of the metal retaining ring 5 is 70mm, the outer diameter is 115mm, and the wall thickness is 22mm.

[0053] The beneficial effects of adopting the above technical solution are: the rectangular cross-section provides a uniform sensing surface, which improves the consistency of detection.
