The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The invention mainly combines a plurality of weight limit value settings and alarm settings through an automatic control system to ensure that the weight and the thickness of the product meet the requirements and finally realize the stable quality of the product.

Example 1

In an exemplary embodiment, as shown in FIG. 1, a method for controlling thickness and weight of an asphalt web product is provided, the method comprising:

setting the rated weight of a target asphalt coiled material product; respectively setting two upper limit values and two lower limit values according to the rated weight, wherein the two upper limit values comprise an allowable deviation upper limit value and a limit deviation upper limit value, and the lower limit value comprises an allowable deviation lower limit value and a limit deviation lower limit value;

measuring the weight of a target asphalt coiled material product in real time to obtain measurement data, and comparing the measurement data with two upper limit values and two lower limit values;

when the measurement data are located between the upper limit value of the allowable deviation and the upper limit value of the limit deviation or between the lower limit value of the allowable deviation and the lower limit value of the limit deviation, performing thickness adjustment alarm; and when the maximum measured value exceeds the upper limit value of the limit deviation or is lower than the lower limit value of the limit deviation, a shutdown alarm is carried out.

Specifically, the greater the thickness of the bitumen coil product, the greater the weight, the smaller the thickness, the smaller the weight, the product thickness being proportional to the product weight. The method comprises the steps of rolling, weighing and heat sealing, wherein the weighing stage needs to monitor the weight of the product, and two upper limit values and two lower limit values are respectively set according to the rated weight, wherein the two upper limit values comprise an allowable deviation upper limit value and a limit deviation upper limit value, and the lower limit value comprises an allowable deviation lower limit value and a limit deviation lower limit value.

Further, if the production line is still in normal operation when the alarm of thickness adjustment occurs, the thickness of the product is adjusted by using the production line, and the weight of the product can be adjusted by adjusting the thickness, so that waste and defective products of the product are avoided; if the machine is stopped and the alarm is given, whether the compression roller of the production line is abnormal or not needs to be checked, the adjustment is carried out in time, the generation of waste and defective products is reduced, the weight and the thickness of the product are ensured to meet the requirements, and the stable quality of the product is finally realized.

Further, the weight of each roll of web material is theoretically kept constant after the thickness is determined, which is a method of reflecting the thickness of the product by weight rather than directly detecting the thickness of the product. Setting 2 limit values, namely early warning and direct shutdown, wherein the early warning indicates that the product belongs to a controllable stage and can be directly adjusted; the shutdown indicates that the product is not controllable and needs to be checked for production.

Further, this application just weighs the coiled material after the rolling, and online thickness measurement is very inaccurate problem when avoiding the rolling, and the reason is that the coiled material is in the motion state before the rolling always, and unable accurate thickness measurement under the motion state, secondly, this application does not use optical device thickness measurement, because optical device can't ensure completely measuring angle, in case there is the deviation will cause the data distortion, the coiled material surface can cause the measured data deviation big if a small amount of unevenness positions appear equally.

Example 2

Based on embodiment 1, a method for controlling thickness and weight of an asphalt coiled material product is provided, wherein the thickness adjustment alarm comprises an upper limit alarm and a lower limit alarm, the thickness of the target asphalt coiled material product is adjusted downwards when the upper limit alarm occurs, and the thickness of the target asphalt coiled material product is adjusted upwards when the lower limit alarm occurs.

Specifically, if the weight of the product is within the standard deviation range, no alarm is given, and the production is normally operated; if the alarm occurs and the production line still runs, the upper limit alarm or the lower limit alarm is firstly confirmed, the upper limit alarm indicates that the product is thicker and needs to be timely adjusted downwards, the cost is saved, the lower limit alarm needs to be timely adjusted upwards, the product thickness index is ensured to be qualified, and waste and defective products of the product are avoided.

Further, when the shutdown alarm occurs, the production line is stopped and abnormal problems of the production line are detected.

Further, the method for controlling the thickness and the weight of the asphalt coiled material product is characterized in that the maximum value of the measurement data is compared with two upper limit values and two lower limit values. Specifically, when the asphalt coiled material product enters the weighing stage after being rolled, the process is a motion process, the display value of the weighing equipment is a fluctuation value, when the coiled material is not completely positioned on the weighing device in the motion process, the weighed weight can be greatly reduced, the maximum value measured when the coiled material is completely positioned on the weighing device is the weight of the coiled material, and the maximum value is taken to ensure the accuracy of the measuring result.

the controller 5 is further configured to compare the measurement data with two upper limit values and two lower limit values;

the alarm device 6 is connected with the controller 5 and is used for carrying out thickness adjustment alarm when the measurement data is positioned between the upper limit value of the allowable deviation and the upper limit value of the limit deviation or between the lower limit value of the allowable deviation and the lower limit value of the limit deviation; when the measured data exceeds the upper limit value of the limit deviation or is lower than the lower limit value of the limit deviation, the alarm device 6 carries out shutdown alarm.

and the winding device 1 is used for adjusting the thickness of the target asphalt coiled material product up/down when the thickness adjustment alarm is generated. Reference numeral 2 denotes a transport device for the weighing stage and reference numeral 3 denotes a device for the sealing stage.

Further, in the asphalt coiled material product thickness and weight control system, the weighing device 4 sends the maximum value of the measured data to the controller 5. When the target asphalt coiled material product enters a weighing stage after being rolled, the display value of the weighing device 4 is a fluctuation value due to the motion process, and when the jump value reaches the maximum value, the weight information is input into the controller 5 for judgment, so that the accuracy of measurement is ensured.

Further, the alarm device 6 is an audible and visual alarm or other types of alarm devices. The alarm device 6 is a conventional alarm on the market.

Further, the production line control device 7 comprises a PLC control room and adopts MCGS configuration software.
