Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to an on-line detection equipment for the integrity of glass bottle labels. Background Art

[0002] In modern packaging industry, glass bottles (especially glass bottles in the fields of pharmaceuticals, cosmetics, food, etc.) are important packaging containers, and the integrity detection of their labels has become an indispensable part of quality control and production processes. With the increasing requirements of consumers for product safety and compliance, and the gradual improvement of relevant laws and regulations, the integrity detection of glass bottle labels has become particularly important.

[0003] Since the 1980s, significant progress has been made in the field of packaging defect detection in various countries. For example, companies such as Haifu in Germany have launched advanced on-line defect detection systems, which can conduct quality inspections on empty and full bottles, including the identification of bottle body and bottle mouth defects, as well as the inspection of items such as capping, liquid level, and labels. The development of these technologies provides strong technical support for the integrity detection of glass bottle labels. As the main carrier of product information, the integrity of glass bottle labels is directly related to product compliance and market access.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Referring to Figure 1 , an on-line detection device for the integrity of glass bottle labels includes a cabinet 1. A universal wheel 2 is fixedly connected to the bottom of the cabinet 1.

A glass bottle 7 is arranged outside the chain conveyor 3. An electrical component 11 is arranged on one side inside the cabinet 1. The electrical component 11 includes an inverter 15, a switching power supply 18, a contactor 19 and low-voltage components 20 inside. The inverter 15, the switching power supply 18, the contactor 19 and the low-voltage components 20 are all installed inside the cabinet 1. A control component 12 is arranged on the other side inside the cabinet 1. The control component 12 includes a PLC module 14 and an I / O module 17 inside. The PLC module 14 and the I / O module 17 are all installed inside the cabinet 1. An HMI central control interface 13 is installed at one end outside the cabinet 1. An emergency stop switch 16 is installed at the other end outside the cabinet 1;

[0034] Multiple universal wheels 2 are installed at the bottom of the cabinet 1, improving the portability of equipment transfer. The conveying device 5 is controlled by four inverters 15 and adopts the principle of rotary step-by-step acceleration to realize the uniform separation and conveying of glass bottles 7 in a smaller space. The control component 12 and the electrical component 11 are connected through a low-voltage control power signal to the actuator of the electrical component 11 for executing the arithmetic commands of the HMI central control interface 13 and the PLC module 14 in real time. The electrical component 11 and the conveying device 5 are connected through a power supply to execute the output actions of the internal components of the electrical component 11, realizing the operation, separation and conveying of the conveyor belt in different directions and at different speeds for the glass bottle 7. The control component 12 processes the information collected by the detection component 26 through signal transmission, and sends the result to the electrical component 11 for execution after calculation, ensuring that the entire process of component operation is unattended.

[0035] As Figure 1As shown in the figure, a detection component 26 is provided outside the upper end of the cabinet 1 and located on the outer side of the chain conveyor 3. The inside of the detection component 26 includes a detection box 27, a bottle-in confirmation photoelectric sensor 21 (using Keyence laser diffuse reflection sensor PR-FB30P3), a 45° photoelectric detection sensor receiving end 22 (using Keyence transmissive photoelectric sensor PR-F51N3), a 45° photoelectric detection sensor transmitting end 23 (using Keyence transmissive photoelectric sensor PR-F51N3), a 135° photoelectric detection sensor receiving end 24 (using Keyence transmissive photoelectric sensor PR-F51N3), and a 135° photoelectric detection sensor transmitting end 25 (using Keyence transmissive photoelectric sensor PR-F51N3). The detection box 27 is fixedly connected to the cabinet 1. The bottle-in confirmation photoelectric sensor 21, the 45° photoelectric detection sensor receiving end 22, and the 135° photoelectric detection sensor receiving end 24 are fixedly installed on one side inside the detection box 27, and the 45° photoelectric detection sensor transmitting end 23 and the 135° photoelectric detection sensor transmitting end 25 are fixedly installed on the other side inside the detection box 27;

[0036] The detection component 26 is connected to the control component 12 through a signal line for detecting the transmission of the bottle label integrity information of the glass bottle 7, receiving the inspections of each photoelectric sensor, judging the data of the glass bottle 7 label integrity, and finally the control component 12 outputs the integrity detection result of the glass bottle 7 label after calculation, realizes the effective rejection of unqualified products, ensures 100% qualification of the online products. The detection component 26 is sequentially connected in series with the bottle-in confirmation photoelectric sensor 21, the 45° photoelectric detection sensor transmitting end 23 and the 45° photoelectric detection sensor receiving end 22, the 135° photoelectric detection sensor transmitting end 25 and the 135° photoelectric detection sensor receiving end 24, and through angle cross calculation, realizes the detection function of whether there is a label within a 45° range, and is used to meet the requirements of regulations for the conformity confirmation of online products.

[0037] As Figure 1 As shown in the figure, the detection component 26 is connected to the PLC module 14 and the I / O module 17 through signal lines. The control component 12 is connected to the HMI central control interface 13 bidirectionally through Ethernet. The control component 12 and the electrical component 11 are connected to the electrical component actuator through a low-voltage control power signal. The electrical component 11 is connected to the conveying device 5 and the chain conveyor 3 through a power supply. The detection component 26 is connected to the control component 12 through a signal line;

[0038] The HMI central control interface 13 is used for the operation of human-machine information exchange. The interface is designed with a setting window for the control parameters of the frequency converter 15, the counting function of the total number of bottles in and the number of qualified and unqualified products, to ensure material balance, and the design of the alarm indicator 6 and the emergency stop switch 16, which is convenient for reminding the operator of the production line operation status and handling emergencies.

[0039] The implementation principle of this embodiment is as follows: During the actual use of the detection device, the device directly replaces a section of the conveyor belt in the production line. Through the switch on the central control interface, various parameters are set during the online product conveying and label detection processes. The HMI central control interface 13 integrates the material balance counting function, which can monitor and accurately count the quantity change and status information of the materials on the conveying device 5 in real time;

[0040] The conveying device 5 is installed outside the cabinet 1 and is responsible for smoothly, efficiently and safely conveying the materials from the previous process step to the next work station. The frequency converter 15 is used to control the rotation to gradually accelerate, and through a special separation and conveying mechanism, it ensures that the glass bottles 7 maintain a uniform spacing during the conveying process.

[0041] The detection component 26 realizes the individual detection of the labels of the glass bottles 7 evenly conveyed on the conveyor belt. It adopts the technology of angular cross calculation. Through the collaborative work and accurate calculation of multiple high-performance photoelectric sensors, it can accurately capture the information of whether there is a label on the entire circumference of the glass bottle 7 and transmit this information to the control component 12 in real time for processing and analysis.

[0042] The control component 12 sets parameters for the HMI central control interface 13 and collects data from the detection component 26 to achieve precise control and coordinated operation of the device, and jointly undertakes the key tasks of the automatic operation and efficient electrical connection of the device with the electrical component 11.
