Abstract

A quality detection sensor for a beverage bottle cap (3) can prevent the missing detection of beverage bottles having screw-slipping caps which are caused by a screw thread quality problem. Said detection sensor comprises a sensor support (1), an end face (11) of the sensor support (1) is provided with three or more photoelectric sensor probes (2) arranged in an annular array, and the photoelectric sensor probes (2) are provided in radial tracks (12). The distance between the end face of the cap (3) and the end face of the detection sensor support (1) is detected simultaneously by means of a plurality of photoelectric sensor probes (2), and the cap (3) is considered to be flat and non-defective only when detection data of the plurality of photoelectric sensor probes (2) are equal in a certain error range, and moreover, if the cap (3) is inclined in a capping process due to a screw thread quality problem, distances between a plurality of points distributed on the end face of the cap (3) in an annular array manner and the end face (11) of the detection sensor support (1) are not equal, such that data of the plurality of photoelectric sensor probes (2) are different, and therefore the inclination situation of the cap (3) can be detected by means of said sensor.

Description

Beverage bottle cap quality detecting sensor

Technical field

The invention relates to the technical field of food processing machinery and equipment, in particular to a beverage bottle cover quality detecting sensor.

Background technique

In the process of sealing the beverage bottle cap, after the beverage bottle is capped, it is necessary to use a photoelectric sensor to detect the capping condition, and then sort out the bottle of the defective capping product. The existing beverage bottle cap quality sensor usually uses a photoelectric sensor to detect the distance between the photosensor probe and the cap. If the distance is not within the set parameter, the cap is considered not to be packaged, and the photoelectric sensor sends an alarm signal. Workers who are at the photoelectric sensor inspection station remove the poorly capped beverage bottles from the conveyor belt. However, the beverage bottle cap sensor of this structure can only cope with the case where the capping error is large or there is no capping, and in actual use, the tilting of the cap of the plastic cap due to the quality of the screw can not be dealt with. This results in the condition that the quality-checked beverage bottle still has a sliding cover, which also causes the finished product of the sliding-capped beverage to reach the consumer directly, which has an impact on the reputation of the manufacturer's product quality.

Summary of the invention

The object of the present invention is to provide a beverage bottle cap quality detecting sensor, which can more accurately detect the quality of the cap and prevent the slippery capping beverage bottle caused by the quality problem of the screw.

A beverage bottle closure quality detecting sensor according to the present invention, comprising a sensor holder, the end surface of the sensor holder being provided with three or more photoelectric sensor probes arranged in an annular array, the photoelectric sensor probe being disposed in a radial orbit in.

The beverage bottle cap quality detecting sensor of the invention simultaneously detects the distance between the end face of the cap and the end face of the detecting sensor bracket through a plurality of photosensor probes, and only the detecting data of the plurality of photosensor probes are equal within a certain error range It is considered that the cover is flat and good, and if the cover is tilted during the capping process due to the quality of the screw, the end face of the cover is arranged in an annular array and the end face of the detecting sensor bracket The distances are not equal, so there will be different data of the photoelectric sensor probes, so the sensor can detect the tilting of the cover, avoiding the leakage detection of the sliding capping beverage bottle caused by the quality problem of the screw, and ensuring the product quality; When the production line is replaced with a different type of cover, the position of the detection point can be adjusted by adjusting the photosensor in a radial direction.

Further, the photosensor probes have three and are arranged in a shape of a character. In practical applications, only three points are required to ensure that the tilt of the cover is detected. Therefore, only three photoelectric sensor probes arranged in a shape of a letter can be used, which simplifies the circuit structure and saves costs.

Detailed ways

The specific embodiments of the present invention, such as the shape and structure of the components involved, the mutual position and connection relationship between the parts, the functions and working principles of the parts, etc., are further described below with reference to the accompanying drawings. Detailed description.

As shown in Fig. 1, the beverage bottle cap quality detecting sensor of the present invention comprises a sensor holder 1, and an end face 11 of the sensor holder 1 is provided with a photosensor probe 2 arranged in an annular array, and the photosensor probe 2 is disposed in the radial track 12.

The beverage bottle cap quality detecting sensor of the present invention simultaneously detects the distance between the end surface 31 of the cap 3 and the end surface 11 of the detecting sensor holder 1 through the plurality of photosensor probes 2, and only the detection data of the plurality of photosensor probes 2 are If the certain error range is equal, the cover is considered to be flat and good, and if the cover 3 is tilted during the capping process due to the quality of the screw, the end face 31 of the cover 3 is arranged in an annular array. The distance between the multiple points and the end surface 11 of the detecting sensor holder 1 is not equal, so that the data of the plurality of photoelectric sensor probes 2 are different, so that the sensor can detect the tilting of the cover 3, thereby avoiding the missed detection due to the quality of the thread. The slippery capping beverage bottle caused by the problem ensures the quality of the product; when the production line is replaced with a different type of cap, the position of the detecting point can be adjusted by adjusting the photosensor 2 along the radial track 12.

As a preferred embodiment, the photosensor probe 2 has three and is arranged in a shape of a character. In practical applications, only three points are required to ensure that the tilt of the cover 3 is detected. Therefore, only three photoelectric sensor probes 2 arranged in a shape of a shape are needed, which simplifies the circuit structure and saves cost.

Example 1:

As shown in FIG. 2 and FIG. 3, the cover 3 in the figure is a commonly used flat top beverage bottle cover, and the distance between the point A, the point B, and the point C of the photosensor probe 2 to the end surface 11 of the sensor holder 1 can be detected. Cover 3 quality inspection.

Example 2:

As shown in Fig. 4 and Fig. 5, the cover of the cover 3 is usually used for the concave top beverage bottle cover. If the center of the concave top cover is not flat, the photosensor probe 2 can be used to detect the cover edge annular flange 32. The distance between the point A', the point B', and the point C' to the end face 11 of the sensor holder 1 achieves the quality detection of the cover 3.
