Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, and more specifically to a device for monitoring the running state of a material feeding roller of a tobacco storage cabinet. Background Art

[0002] In the silk production process, storage cabinets are widely used. Storage cabinets are important equipment for storing materials in the silk workshop of cigarette factories. When the storage cabinet is unloading, the bottom belt and the feed roller cooperate to evenly transport the materials in the storage cabinet to the next level of equipment. At present, due to the long service life of our factory's storage cabinet equipment, there are problems of aging and wear. During the operation of the storage cabinet feed roller, there are problems such as chain disconnection, feed roller shaft breakage, and bearing jamming. The operation status detection function of our equipment only performs dynamic monitoring on electrical components, and the operation status of mechanical components cannot be monitored. This results in that when a fault occurs, the maintenance personnel conduct a large-scale investigation and cannot directly determine the equipment fault point in the first time, which brings unnecessary trouble to maintenance and production.

The wincc screen is connected to the PLC system for communication.

[0037] Specific working principle:

[0038] 1. The first sensing sheet 5 is driven to rotate by the first material-moving roller shaft 4. Every time the first material-moving roller shaft 4 rotates one circle, the first sensing sheet 5 also rotates one circle, and senses the first proximity switch 7 once at a fixed position.

[0039] 2. The second sensing sheet 12 is driven to rotate by the second material-moving roller shaft 11. Every time the second material-moving roller shaft 11 rotates one circle, the second sensing sheet 12 also rotates one circle, and senses the second proximity switch 14 once at a fixed position.

[0040] 3. The third sensing sheet 19 is driven to rotate by the third material-shifting roller shaft 18. Every time the third material-shifting roller shaft 18 rotates one circle, the third sensing sheet 19 also rotates one circle, and senses the third proximity switch 21 once at a fixed position.

[0041] Alarm settings:

[0042] The alarm system will automatically enable this function only when it is in automatic operation and the storage cabinet is selected for discharging. The material-discharging roller rotates once every 8 seconds under the drive of the motor reducer. We set the alarm monitoring time to 10 seconds. When the material-discharging roller operates normally, the sensor sheet will definitely sense the proximity switch once within 10 seconds.

[0043] 1. Under the operating conditions of the first material-dispensing roller 4: (1) Within 10 seconds, if the first sensor sheet 5 senses the first proximity switch 7 once, the first proximity switch 7 will send a signal to the PLC system. The system believes that the first material-dispensing roller 4 is operating normally and no alarm will be given. At the same time, when the first sensor sheet 5 senses the first proximity switch 7, the alarm timing will be reset and the timing will be restarted from 0. (2) If the first proximity switch 7 does not receive a sensing signal within 10 seconds, the system believes that the first material-dispensing roller 4 is operating abnormally, and the wincc screen will pop up an alarm box "The first material-dispensing roller 4 is operating abnormally". The system monitoring personnel will call the maintenance personnel in time to perform maintenance as soon as possible until the first material-dispensing roller 4 resumes normal operation. After the first proximity switch 7 receives the sensing signal again, the alarm box on the wincc screen will automatically disappear, and the system will continue to monitor the operating status of the first material-dispensing roller 4 until the storage cabinet finishes discharging and the cabinet selection signal is cancelled. The system will automatically stop monitoring the operation of the first material-dispensing roller 4.

[0044] 2. Under the operating conditions of the second material-dispensing roller 11: (1) Within 10 seconds, if the second sensor sheet 12 senses the second proximity switch 14 once, the second proximity switch 14 will send a signal to the PLC system. The system believes that the second material-dispensing roller 11 is operating normally and no alarm prompt will appear. At the same time, when the second sensor sheet 12 senses the second proximity switch 14, the alarm timing will be reset and the timing will be restarted from 0. (2) If the second proximity switch 14 does not receive a sensing signal within 10 seconds, the system believes that the second material-dispensing roller 11 is operating abnormally, and the wincc screen will pop up an alarm box "The second material-dispensing roller 11 is operating abnormally". The system monitoring personnel will call the maintenance personnel in time to perform maintenance as soon as possible until the second material-dispensing roller 11 resumes normal operation. After the second proximity switch 14 receives the sensing signal again, the alarm box on the wincc screen will automatically disappear, and the system will continue to monitor the operating status of the second material-dispensing roller 11 until the storage cabinet finishes discharging and the cabinet selection signal is cancelled. The system automatically stops the operation monitoring function of the second material-dispensing roller 11.

[0045] 3. Under the operating conditions of the third material-dispensing roller 18: (1) Within 10 seconds, if the third sensor sheet 19 senses the third proximity switch 21 once, the third proximity switch 21 will send a signal to the PLC system. The system believes that the third material-dispensing roller 18 is operating normally and no alarm will be given. At the same time, when the third sensor sheet 19 senses the third proximity switch 21, the alarm timing will be reset and the timing will be restarted from 0. (2) If the third proximity switch 21 does not receive a sensing signal within 10 seconds, the system believes that the third material-dispensing roller 18 is operating abnormally. The wincc screen will pop up an alarm box "The third material-dispensing roller 18 is operating abnormally". The system monitoring personnel will call the maintenance personnel in time to perform maintenance as soon as possible until the third material-dispensing roller 18 resumes normal operation. After the third proximity switch 21 receives the sensing signal again, the alarm box on the wincc screen will automatically disappear. The system will continue to monitor the operating status of the third material-dispensing roller 18 until the storage cabinet is discharged and the cabinet selection signal is cancelled. The system will automatically stop the monitoring function of the operation of the third material-dispensing roller 18.

[0046] The three feed roller monitoring abnormal alarm boxes can appear individually or simultaneously, independently of each other.

[0047] In summary, the technical content disclosed by the utility model is to install metal sensing sheets on the end faces of the three feed roller shafts and to install proximity switches on the nearest guard plates. The rotation of the feed roller drives the sensing sheets to rotate, so that the sensing sheets should sense the proximity switches at specific positions and times as conditions to judge the running status of the feed rollers. When a feed roller fails, the specific fault point can also be judged by the states of the three proximity switch detection signals, thus realizing the status monitoring and fault alarm functions of mechanical components, improving the equipment running status monitoring function, improving the accuracy of equipment fault status judgment, and improving the intelligence level of the equipment.
