The preferred embodiments of the present application will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein only to illustrate and explain the present application and not to limit the present application.
Fig. 1 is a flowchart illustrating a method for safely starting an adhesive tape machine according to an embodiment of the present application, and as shown in fig. 1, the method may be implemented as the following steps S101 to S106:
in step S101, when a triggering operation of starting the adhesive tape machine is received, acquiring preset parameter information of the adhesive tape machine;
in step S102, determining whether the tape machine has a fault according to the preset parameter information;
in step S103, when the tape machine has a fault, the tape machine is turned off, and the fault type of the tape machine is determined;
in step S104, determining whether the tape machine fault is repairable or not according to the fault type of the tape machine;
in step S105, when the failure of the tape machine can be repaired, the failure of the tape machine is repaired;
in step S106, when the fault repairing of the tape machine is successful, the tape machine is restarted.
The execution main body of the application can be a safe starting system of the adhesive tape machine, wherein the safe starting system of the adhesive tape machine can acquire various kinds of operation parameter information of the adhesive tape machine, judge whether the adhesive tape machine has faults or not based on the operation parameter information, judge the fault type of the adhesive tape machine, judge whether the fault of the adhesive tape machine can be repaired or not based on the fault type of the adhesive tape machine, and start the adhesive tape machine when the fault of the adhesive tape machine is successfully repaired.
In this embodiment, when a triggering operation of starting the tape machine is received, preset parameter information of the tape machine is obtained, and the tape machine safety starting system may determine whether the tape machine has a fault based on the preset parameter information, for example, the preset parameter of the tape machine may be a parameter output by a tape machine control system, and determine whether the tape machine has a fault by determining whether a fault code is included in the parameter output by the tape machine; for another example, the preset parameters of the adhesive tape machine may also be a belt tension received by a travelling trolley in the belt bin, a tension of the adhesive tape machine, a torque of the main transmission roller, a torque of the auxiliary transmission roller, a pressure value of a hydraulic system of the adhesive tape machine, and the like.
Judging whether the adhesive tape machine has a fault according to the preset parameter information; when the belt conveyor is not in fault, the starting state of the belt conveyor is continuously maintained;
when the belt conveyor has a fault, closing the belt conveyor, and determining the fault type of the belt conveyor;
specifically, for example, when a fault code is output in a belt conveyor control system, it is determined that a belt conveyor has a fault, and for example, when a belt tension received by a travelling trolley in a belt bin is smaller than a first threshold, when an absolute value of a difference value between a main driving roller torque and a secondary driving roller torque of the belt conveyor reaches a second threshold, when a tension value of the belt conveyor exceeds a preset interval, and when a pressure value of a belt conveyor hydraulic system is smaller than a third threshold, the belt conveyor is considered to have a fault.
Wherein, when the adhesive tape machine control system outputs a fault code, the fault type of the adhesive tape machine is determined to be the electric fault of a frequency converter, specifically, the frequency converter of the adhesive tape machine mainly comprises a driving frequency converter and a tensioning frequency converter, the adhesive tape machine control system can be connected with the driving frequency converter and the tensioning frequency converter, further detecting the driving frequency converter and the tensioning frequency converter, further automatically judging whether the driving frequency converter and the tensioning frequency converter have faults or not, when a fault exists, a fault code corresponding to the electric fault of the driving frequency converter or the electric fault of the tensioning frequency converter is output, it needs to be noted that the fault codes of the electric fault of the driving frequency converter and the electric fault of the tensioning frequency converter are different, and a worker can further judge whether the electric fault of the frequency converter is the electric fault of the driving frequency converter or the electric fault of the tensioning frequency converter by looking up the fault code output by the adhesive tape machine control system.
Secondly, determining the fault type of the adhesive tape machine further comprises:
when the belt tension received by a travelling trolley in a belt bin is smaller than a first threshold value, determining that the fault type of the belt conveyor is that the driving acceleration is overlarge; fig. 4 is a schematic structural diagram of an adhesive tape machine, as shown in fig. 4, since a belt of the adhesive tape machine is too long, after the belt conveyor is started, the belt near the driving device starts to move first, and since the belt has a large elasticity, a pulling force of the driving device is gradually transmitted to the entire belt from near to far, so that after the adhesive tape machine is started, the belt of the adhesive tape machine rotates in the adhesive tape machine driving device 402, an amount of the belt in the belt bin increases, and in case of the increased amount of the belt in the belt bin, the controller 403 pulls the traveling trolley 4011 to move away from the driving device 402, so that the belt in the belt bin is kept in a tensioned state. If the driving acceleration is set to be too large, the pulling speed of the moving trolley 4011 cannot keep up with the increasing amount of the belt, at the moment, the tension of the belt received by the moving trolley 4011 is small, the belt can incline and fall off, and the like, so that the driving acceleration is not too small. In view of the above, there is a need to find a scheme capable of determining an appropriate driving acceleration, specifically, obtaining the number of protection blocking points along the line of the tape machine according to a sensor, determining the acceleration time of the driving according to the number of protection blocking points along the line and a preset relation table, and controlling the driving acceleration according to the acceleration time. The preset relation table stores the corresponding relation among the number of the locking points, the length of the belt conveyor and the acceleration time. And the control scheme for the driving acceleration may be a fuzzy control scheme based on an acceleration time. The preset relationship table is shown in table 1 below:
TABLE 1
| Length m | Acceleration time s | Length judgment (number of locking points) |
| 0-3000 | 120 | 0-30 |
| 3000-4000 | 150 | 30-40 |
| 4000-5000 | 180 | 40-50 |
| 5000-6000 | 210 | 50-60 |
When the absolute value of the difference value of the torque of the main transmission roller and the torque of the auxiliary transmission roller of the belt conveyor reaches a second threshold value, determining that the fault type of the belt conveyor is power imbalance; specifically, because the rollers are sprayed with water or stressed unevenly, the problem of inconsistent output torque among multiple driving rollers, namely power imbalance, is easily caused in the starting stage of the adhesive tape machine. The judgment can be carried out through the output torque value of the motor, and if the power imbalance occurs, the judgment method comprises the following steps: if the absolute value of the torque difference N1-N2 between the main driving roller and the auxiliary driving roller is 10% or more and is more than or equal to | the torque difference | is more than or equal to 5% (namely a second threshold), and the torque difference lasts for more than 3s, the slip is considered to be the power imbalance, the main controller of the adhesive tape machine sends an instruction to the driving controller, the speed value of the auxiliary driving roller is adjusted by fine adjustment, if N1-N2 is positive, the speed of the auxiliary driving roller is increased, the torque is increased, if N1-N2 is negative, the speed of the auxiliary driving roller is reduced, the torque is reduced, the speed adjustment amplitude is not more than 1%, and the power imbalance problem is corrected.
When the tension value of the belt conveyor exceeds a preset interval, determining that the fault type of the belt conveyor is a tension fault;
specifically, the tension force is judged, and the adaptive tension force of the adhesive tape machine can be known according to an Euler formula. The known maximum tension points are: smaxThe maximum tension can be calculated according to the motor torque value and the reduction ratio output by the belt conveyor controller and the diameter of the roller, so that the value is known, and the actual requirement of the tension of the belt conveyor is further calculated. Checking and calculating system tension S according to slip conditionmin≥Smax/(eμα-1), wherein a is the wrapping angle radian of the belt surface of the adhesive tape machine and the roller; mu is the friction coefficient between the belt surface of the belt conveyor and the drum skin. Combined with field use, by fuzzy estimation, Smax≈3.66·SminThe tension can be controlled at Smax10 to SmaxWithin the interval of/9 (i.e., the preset interval). And the on-site main controller checks the tension feedback value in real time, and if the tension feedback value is not in the preset interval, the on-site main controller sends an instruction to adjust the tension variable frequency controller, so that tension self-repairing can be performed on tension control.
When the pressure value of the hydraulic system of the adhesive tape machine is smaller than the third threshold value, the fault type of the adhesive tape machine is determined to be a pressure fault, specifically, the adhesive tape machine is divided into a foundation type and a foundation-free type, the foundation-free adhesive tape machine needs to be supported and fixed by the hydraulic system, the pressure value needs to be detected by the control system in real time, a safety threshold value (namely the third threshold value) of the pressure can be set, and when the pressure value of the hydraulic system of the adhesive tape machine is smaller than the safety threshold value, the adhesive tape machine is determined to have the pressure fault.
Judging whether the failure of the adhesive tape machine can be repaired or not according to the failure type of the adhesive tape machine; specifically, when the fault type of the belt conveyor is an electrical fault of a frequency converter, it is determined that the fault of the belt conveyor cannot be repaired. Determining that the belt machine fault is repairable when the fault type of the belt machine is at least one of the following fault types: excessive drive acceleration, power imbalance, tension failure, and pressure failure.
When the fault of the adhesive tape machine can be repaired, the fault of the adhesive tape machine is repaired; specifically, the method comprises the following steps: when the fault type of the belt conveyor is that the driving acceleration is overlarge, adjusting the acceleration time of the driving controller according to the actual length of the belt conveyor so as to reduce the driving acceleration; when the fault type of the belt conveyor is power unbalance, adjusting the speed of the auxiliary transmission roller to reduce the absolute value of the difference value of the main transmission roller torque and the auxiliary transmission roller torque to be smaller than a second threshold value; when the fault type of the belt conveyor is a tension fault, adjusting the tension of the belt conveyor through a tension variable frequency controller so that the tension of the belt conveyor falls into the preset interval; when the fault type of the belt conveyor is a pressure fault, pressure supplementing is carried out through a hydraulic controller, so that the pressure of the hydraulic system is increased to be larger than or equal to the third threshold value.
And when the fault of the adhesive tape machine is successfully repaired, the adhesive tape machine is restarted.
And when the fault of the adhesive tape machine can not be repaired, sending out the prompt message of the fault of the adhesive tape machine.
The beneficial effect of this application lies in: before the sealing-tape machine starts, whether the sealing-tape machine has a fault can be automatically judged according to preset parameter information, the fault of the sealing-tape machine can be repaired when the fault of the sealing-tape machine can be repaired, manual detection is not needed, the labor cost is saved, the repairable fault can be repaired without manual repair, and the labor cost is further saved.
In one embodiment, the method may also be implemented as the steps of:
and when the fault of the adhesive tape machine can not be repaired, sending out the prompt message of the fault of the adhesive tape machine.
The beneficial effect of this embodiment lies in: when the fault of the adhesive tape machine cannot be repaired, the prompt message of the fault of the adhesive tape machine is sent, the further expansion of the fault caused by the starting of the adhesive tape machine under the condition of the fault is avoided, and the safety of the adhesive tape machine is improved.
In one embodiment, the method may also be implemented as the steps of:
when the belt conveyor has no fault, the starting state of the belt conveyor is continuously maintained.
The beneficial effect of this embodiment lies in: the sealing-tape machine is started only after the sealing-tape machine is cleared of faults, and the safety of the sealing-tape machine is improved.

In the embodiment, when the belt tension received by the travelling trolley in the belt bin is smaller than a first threshold value, the fault type of the belt conveyor is determined to be that the driving acceleration is overlarge; fig. 4 is a schematic structural diagram of an adhesive tape machine, as shown in fig. 4, since a belt of the adhesive tape machine is too long, after the belt conveyor is started, the belt near the driving device starts to move first, and since the belt has a large elasticity, a pulling force of the driving device is gradually transmitted to the entire belt from near to far, so that after the adhesive tape machine is started, the belt of the adhesive tape machine rotates in the adhesive tape machine driving device 402, an amount of the belt in the belt bin 401 increases, and in case that an amount of the belt in the belt bin 401 increases, the controller 403 pulls the traveling trolley 4011 to move away from the driving device 402, so that the belt in the belt bin maintains a tensioned state. If the driving acceleration is set to be too large, the pulling speed of the moving trolley 4011 cannot keep up with the increasing amount of the belt, at the moment, the tension of the belt received by the moving trolley 4011 is small, the belt can incline and fall off, and the like, so that the driving acceleration is not too small. In view of the above, there is a need to find a scheme capable of determining an appropriate driving acceleration, specifically, obtaining the number of protection blocking points along the line of the tape machine according to a sensor, determining the acceleration time of the driving according to the number of protection blocking points along the line and a preset relation table, and controlling the driving acceleration according to the acceleration time. The preset relation table stores the corresponding relation among the number of the locking points, the length of the belt conveyor and the acceleration time. And the control scheme for the driving acceleration may be a fuzzy control scheme based on an acceleration time. The preset relationship table is shown in table 1 below:
TABLE 1
| Length m | Acceleration time s | Length judgment (number of locking points) |
| 0-3000 | 120 | 0-30 |
| 3000-4000 | 150 | 30-40 |
| 4000-5000 | 180 | 40-50 |
| 5000-6000 | 210 | 50-60 |
When the absolute value of the difference value of the torque of the main transmission roller and the torque of the auxiliary transmission roller of the belt conveyor reaches a second threshold value, determining that the fault type of the belt conveyor is power imbalance; specifically, because the rollers are sprayed with water or stressed unevenly, the problem of inconsistent output torque among multiple driving rollers, namely power imbalance, is easily caused in the starting stage of the adhesive tape machine. The judgment can be carried out through the output torque value of the motor, and if the power imbalance occurs, the judgment method comprises the following steps: if the absolute value of the torque difference N1-N2 between the main driving roller and the auxiliary driving roller is 10% or more and is more than or equal to | the torque difference | is more than or equal to 5% (namely a second threshold), and the torque difference lasts for more than 3s, the slip is considered to be the power imbalance, the main controller of the adhesive tape machine sends an instruction to the driving controller, the speed value of the auxiliary driving roller is adjusted by fine adjustment, if N1-N2 is positive, the speed of the auxiliary driving roller is increased, the torque is increased, if N1-N2 is negative, the speed of the auxiliary driving roller is reduced, the torque is reduced, the speed adjustment amplitude is not more than 1%, and the power imbalance problem is corrected.
When the tension value of the belt conveyor exceeds a preset interval, determining that the fault type of the belt conveyor is a tension fault;
specifically, the tension force is judged, and the adaptive tension force of the adhesive tape machine can be known according to an Euler formula. The known maximum tension points are: smaxThe maximum tension can be calculated according to the motor torque value and the reduction ratio output by the belt conveyor controller and the diameter of the roller, so that the value is known, and the actual requirement of the tension of the belt conveyor is further calculated. Checking and calculating system tension S according to slip conditionmin≥Smax/(eμα-1), wherein a is the wrapping angle radian of the belt surface of the adhesive tape machine and the roller; mu is the friction coefficient between the belt surface of the belt conveyor and the drum skin. Combined with field use, by fuzzy estimation, Smax≈3.66·SminThe tension can be controlled at Smax10 to SmaxWithin the interval of/9 (i.e., the preset interval). And the on-site main controller checks the tension feedback value in real time, and if the tension feedback value is not in the preset interval, the on-site main controller sends an instruction to adjust the tension variable frequency controller, so that tension self-repairing can be performed on tension control.
When the pressure value of the hydraulic system of the adhesive tape machine is smaller than the third threshold value, the fault type of the adhesive tape machine is determined to be a pressure fault, specifically, the adhesive tape machine is divided into a foundation type and a foundation-free type, the foundation-free adhesive tape machine needs to be supported and fixed by the hydraulic system, the pressure value needs to be detected by the control system in real time, a safety threshold value (namely the third threshold value) of the pressure can be set, and when the pressure value of the hydraulic system of the adhesive tape machine is smaller than the safety threshold value, the adhesive tape machine is determined to have the pressure fault.
In one embodiment, the step S104 can be implemented as the following steps:
and when the fault type of the belt conveyor is the electrical fault of the frequency converter, determining that the fault of the belt conveyor cannot be repaired.
In one embodiment, the step S104 can be implemented as the following steps:
determining that the belt machine fault is repairable when the fault type of the belt machine is at least one of the following fault types:
excessive drive acceleration, power imbalance, tension failure, and pressure failure.
In one embodiment, as shown in FIG. 3, the above step S105 can be implemented as the following steps S301-S304:
in step S301, when the failure type of the tape machine is that the driving acceleration is too large, adjusting the acceleration time of the driving controller according to the actual length of the tape machine to reduce the driving acceleration;
in step S302, when the failure type of the tape machine is power imbalance, adjusting the speed of the secondary driving roller to reduce the absolute value of the difference between the main driving roller torque and the secondary driving roller torque to be less than a second threshold;
in step S303, when the failure type of the adhesive tape machine is a tension failure, adjusting a tension of the adhesive tape machine by a tension variable frequency controller so that the tension of the adhesive tape machine falls into the preset interval;
in step S304, when the type of the failure of the tape machine is a pressure failure, performing pressure compensation by a hydraulic controller to increase the pressure of the hydraulic system to be greater than or equal to the third threshold value.
