Description

Technical Field

[0001] This invention relates to a method for diagnosing and handling cable jamming faults in a packaging machine, belonging to the technical field of packaging machine fault diagnosis methods. Background Technology

[0002] Nowadays, a large number of mechanical structures are used in industrial production processes, among which the packing machine is one.

[0003] Packing machines frequently experience malfunctions during use, some of which can severely impact their operation. Among these malfunctions, cable jamming is one such issue. In practice, when cable jamming is detected, if the cable end is found to be long, the usual approach is to adjust the S2 signal on-site. If this doesn't work, the S2 mechanism is replaced. However, this method is sometimes ineffective. On average, each attempt to resolve cable jamming takes 30 minutes, which is time-consuming and labor-intensive, significantly reducing the efficiency of troubleshooting. Furthermore, replacing the S2 mechanism leads to resource waste, necessitating improvements. Summary of the Invention

It has good performance, and is safe, environmentally friendly, and efficient, effectively solving the aforementioned problems in the background technology.

[0005] The technical solution of the present invention is: a method for diagnosing and handling cable jamming faults in a packaging machine, comprising the following steps: (1) When a packing machine jams, record the time on site; (2) Retrieve the PDA for preliminary inspection; (3) If the feed line slows down first and then the S2 signal goes out, it means that the S2 signal feedback adjustment is not appropriate. (4) If the S2 signal goes out first and the speed decreases after the wire is sent, it indicates that the loss of rotation or loss of data has caused the wire to be stuck due to unstable wire threading. (5) After diagnosing the cable jamming fault of the packaging machine, record the information data; (6) Select a specific time period and record the number of times the packing machine experiences wire jamming failures and the causes of the failures; (7) Classify and process the data information; (8) Provide manufacturers with production recommendations based on the processed information.

The adjustment can be completed on the packaging machine operating table without stopping the machine. The adjustment can be done while packaging.

[0007] In step (4), if the S2 signal goes out first and the speed decreases after the wire is sent, it indicates that the loss of rotation or number of turns has caused the wire to be stuck due to unstable wire threading. The length of the stuck wire end is uncertain.

[0008] In step (4), if the S2 signal goes out first and the speed decreases after the wire is sent, it indicates that the loss of rotation or number of turns has caused the wire to be stuck due to unstable wire threading. Specifically, the steps are as follows: (401) Observe whether the wire feeding wheel or wire pressing wheel is worn; (402) Observe whether the packing line is uniform and whether the thickness is appropriate, and use calipers to measure the data; (403) The code disk shaft slipped, causing it to lose rotation. Disassemble and inspect.

[0011] In step (403), the code disk shaft slips, causing it to lose rotation. It is then disassembled for inspection, a process that takes 5-10 minutes.

[0012] In step (5), after determining the fault of the packing machine cable jam, the information data is recorded and entered into the database.

[0013] In step (6), a time period of 1-2 years is selected to record the number of times the packaging machine experiences wire jamming failures and the causes of the failures.

[0014] In step (7), the causes and frequency of the corresponding packing machine jamming are integrated, and the packing machine failure rate data within the time period is obtained, while the frequency of the cause of failure is also obtained; in step (8), production suggestions are given to the manufacturer based on the processed information, including production improvement suggestions for frequently failing structures and suggestions for improving the packing line.

[0033] In Examples 1-2, a time period of one year was selected, and the number of cable jam failures was found to be 32. The profit per ton of steel produced is 170 yuan, with 500 tons produced per shift and a shift lasting 8 hours. The time saved can generate a profit of 32 * (30 - 10) * (500 / 8 / 60 * 170) = 113,000; The time-saving benefit is (30-10)*55*32=35,000 yuan; The total time saved and the resulting economic benefits = 11.3 + 3.5 = 14.8 million yuan.

[0034] Using this judgment and processing method based on the calculated surface can greatly improve economic efficiency.
