A filling device for automatically identifying and rejecting preforms

Abstract

The utility model relates to a filling automatic identification and rejection device for bottle preforms, which comprises a PLC controller, an optical fiber sensor, a mounting bracket, a rejection cylinder, a station coding sensor, and an electromagnetic valve. When the rejection device is in use, the optical fiber sensor detects products on a conveyor belt, thereby distinguishing the bottle preforms from the bottle bodies of the products. If the product is a bottle preform, the PLC controller controls the electromagnetic valve to open, and the corresponding rejection cylinder is actuated to reject the bottle preform. In addition, the optical fiber sensor is arranged on the mounting bracket, and the mounting bracket comprises a base, a slider arranged on the base, and a universal adjustment seat mounted on the top of the slider. The optical fiber sensor is mounted on the universal adjustment seat. When the slider moves on the base, the mounting position of the optical fiber sensor can be adjusted. When the universal adjustment seat rotates, the mounting angle of the optical fiber sensor can be adjusted. The sensing accuracy of the optical fiber sensor is relatively high.

Description

Technical Field

[0001] The utility model relates to the field of bottle preform rejection equipment, in particular to a device for automatically identifying and rejecting bottle preforms during filling. Background Art

[0002] At present, the conveying mode of the bottle washing mechanism is: the product enters the connecting finger → enters the bottle body inspection → rejects the unqualified bottles. When there are too many preforms, they cannot be completely rejected, causing the preforms to flow into the filling, resulting in equipment downtime, welding cover cold welding and other quality risks. Therefore, the process of rejecting unqualified bottles requires higher precision. When the current rejection device is used, there is a problem that the unqualified bottles cannot be detected in place. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A filling and automatic identification and rejection device for bottle embryos, comprising a PLC controller, an optical fiber sensor, a mounting bracket, a rejection cylinder, a station coding sensor, and a solenoid valve;

[0006] PLC controller is suitable for controlling program logic;

[0007] Fiber optic sensors are suitable for distinguishing between preforms and bottles;

[0008] The mounting bracket is suitable for adjusting the installation position and angle of the optical fiber sensor;

[0009] The reject cylinder is suitable for rejecting preforms;

[0010] The position coding sensor is suitable for sensing the workstation, which is convenient for the PLC controller to perform position coding;

[0011] The solenoid valve is connected to the reject cylinder.

[0012] Furthermore, the optical fiber sensor is arranged below the conveyor belt.
