Description

Technical Field

[0001] The utility model relates to the technical field of tire production and manufacturing, and more specifically to an automatic counting device for ultrasonic cutters used in all-steel truck and passenger tire building machines. The device is easy to operate and has accurate counting capabilities, and can effectively measure the number of times an ultrasonic cutter is operated on a tire building machine, thereby providing an accurate basis for processes such as loading, starting and stopping the machine during the production process, and improving product production efficiency. Background Art

[0002] As is well known, the ultrasonic cutters used in all-steel truck tire building machines within tire companies' factories are currently manually counted and recorded according to the number of qualified products produced during the shift. This presents the following issues: 1. Manually recording and counting each shift is based on the production volume of that shift. Waste is inevitably generated during the production process. While the ultrasonic cutter performs cutting when waste is generated, this is not reflected in the records of qualified products during the shift, leading to inevitable numerical errors. 2. The personnel responsible for counting and calculating the ultrasonic cutter numbers inevitably make mistakes, omissions, or errors during the recording and accounting process, resulting in inaccurate information and a heavy workload, increasing the company's labor costs. 3. Manually recording and counting each shift has a long cycle, and information sharing is not timely, making it difficult to effectively monitor the process. This greatly complicates verification, impacting product traceability and quality.

[0003] With the rapid development of the economy and the increasing degree of equipment automation, it is becoming more and more urgent to improve production efficiency and reduce unnecessary waste of manufacturing costs. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the utility model proposes an automatic ultrasonic cutter counting device for an all-steel truck and passenger tire building machine that utilizes an RFID mechanism for automatic reading and verification, realizes automatic counting, alarming, real-time monitoring, and precise management of ultrasonic cutters, which is beneficial to improving production efficiency and product quality, reducing costs and risks, and reducing unnecessary waste.

[0005] The utility model is achieved through the following measures:

[0006] An automatic counting device for ultrasonic cutters used in all-steel truck and passenger tire building machines is characterized by being provided with a host computer, an RFID reader / writer component, an RFID tag, and a position detection circuit. The host computer is connected to the RFID reader / writer component and the position detection circuit respectively. The RFID reader / writer component is provided with an RFID reader / writer and a radio frequency antenna connected to the RFID reader / writer. The position detection circuit is provided with a photoelectric switch for detecting a signal indicating that the ultrasonic cutter is in position. The host computer is connected to the RFID reader / writer in the RFID reader / writer component via a serial communication circuit. The RFID tag is attached to the ultrasonic cutter.

[0007] The photoelectric switch of the utility model is installed on the side of the ultrasonic cutter working position, and the RFID reading and writing component is installed on the side of the ultrasonic cutter working position. In order to improve the detection reliability, two photoelectric switches respectively connected to the host computer can be provided at the cutting working position of the ultrasonic cutter.

[0008] The upper computer of the utility model is provided with a PLC controller and a multi-color indicator light, a buzzer and a display screen connected with the PLC controller, which are used for displaying and outputting counting information of the ultrasonic cutting knife.

[0009] When the utility model is working, the ultrasonic cutter enters the cutting station from the initial position to perform the cutting operation. At this time, the photoelectric switch in the position detection circuit located on the side of the cutting station detects that the cutter has entered the cutting work area, and outputs a trigger signal to the PLC controller. The PLC controller controls the RFID reader to use the radio frequency antenna to read the RFID tag on the ultrasonic cutter. The RFID reader uploads the read tag information to the host computer via the serial communication circuit. The host computer completes storage and counting, and outputs the counting information through the display screen. After the ultrasonic cutter completes the cutting operation, it exits the cutting work area and prepares for the next cutting. Cut, and then the cycle repeats. The photoelectric switch performs the position monitoring process, and the RFID read-write component performs the RFID tag reading operation and feeds back data to the upper computer. By automatically counting the entire cutting process, the shortcomings of traditional manual counting can be effectively avoided. The utility model adopts RFID tag counting instead of traditional photoelectric switch counting. If the ultrasonic cutter is removed and put aside halfway, the use status of the cutter can be obtained by scanning the information of the RFID tag. The label rules are universal and convenient for replacement and maintenance. Only the photoelectric switch sensor can complete the position detection, and the working status of the ultrasonic cutter can only be recorded manually, which is time-consuming and labor-intensive.

[0010] Compared with the prior art, the utility model has the remarkable advantages of reasonable structure, simple operation, convenient maintenance and replacement, accurate recording, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Example:

[0015] This example provides a device capable of automatically counting the cutting work of an ultrasonic cutter used in an all-steel truck and passenger tire building machine. The device comprises a host computer, an RFID reader / writer assembly, an RFID tag 1, and a position detection circuit 3. The host computer is connected to the RFID reader / writer assembly and the position detection circuit 3, respectively. The RFID reader / writer assembly is provided with an RFID reader / writer 4 and a radio frequency antenna 5 connected to the RFID reader / writer 4. The position detection circuit 3 is provided with a photoelectric switch for detecting a position signal of the ultrasonic cutter 2. The host computer is connected to the RFID reader / writer 4 in the RFID reader / writer assembly via a serial communication circuit. The RFID tag 1 is attached to the ultrasonic cutter 2.

[0016] In this example, the host computer is equipped with a PLC controller 6, a three-color alarm light 7, and a display screen 8;

[0017] In this example, when the ultrasonic cutter 2 equipped with an RFID tag 1 cuts the material, it triggers the photoelectric sensor, and the RFID reader 4 automatically reads the RFID tag information on the ultrasonic cutter and sends it to the PLC controller. The PLC controller 6 displays and re-enters the read information respectively. The display is reflected by the numbers on the display screen 8 and the flashing colors of the three-color alarm light 7. The information to be re-entered is sent to the RFID reader / writer component, and the RFID reader / writer component writes the information to be re-entered into the RFID tag. 1 is used to realize the cumulative counting function, wherein when the device is in offline mode: the ultrasonic cutter counting function in the warehouse or under maintenance can be realized by scanning the RFID tag 1 on the ultrasonic cutter with an RFID handheld;

[0018] The PLC controller 6 in the host computer can display the value in the RFID tag information on the display screen, showing the number of times the ultrasonic cutter has been used. It also sends a warning light instruction. A solid green light indicates that the ultrasonic cutter is in normal use, a solid yellow light indicates that the ultrasonic cutter has one use remaining, and a flashing red light indicates that the ultrasonic cutter has been used up and needs to be repaired or replaced. The host computer recalculates the value in the RFID tag information and sends it to the RFID reader / writer. The RFID reader / writer rewrites the new value into the RFID tag on the ultrasonic cutter, realizing the cumulative counting function.
