In order to achieve the purpose, the invention adopts the following technical scheme:
a method for automatically adjusting the weight of an adhesive tape by a rubber tape cutting mechanism comprises the following steps:
collecting the weight m of the cut adhesive tape after the mechanism is started1And length L1；
The weight m of the rubber strip1Comparing with a first preset value m of the system;
when the result of the comparison is the weight m of the adhesive tape1When the length L is not equal to the first preset value m of the system, the mechanism adjusts the length L to be cut of the next adhesive tape2To enter a weight adjustment operation of the adhesive tape, wherein the length adjustment of the adhesive tape satisfies the following formula: l is2＝m/m1×L1. Because the rubber material that needs the slitting can be regarded as the level, slice material that density is even, through weighing system, can obtain the weight of each material, handles the weight information of this material through the procedure to carry out proportional adjustment to feeding system's pay-off distance, the effectual weight adjustment who realizes the adhesive tape has increased work efficiency and has adjusted the precision, has reduced artificial intervention, conveniently has controlled the quality control of stripDo this.
Further, after the weight adjustment operation, the weight m of n adhesive tapes is provided1Satisfies the weight m-d1≤m1≤m+d2When n is more than or equal to 1, the mechanism is suspended for operation, m>d1≥0，m>d2≥0；
Or when the mechanism does not stop, the first preset value of the system is changed from m to m2When and after the weight adjustment operation there are n glue strips of weight m1Satisfy the weight m2-d3≤m1≤m2+d4When n is more than or equal to 1, the mechanism is suspended for operation, m2>d3≥0，m2>d4≥0；
Or n after the weight adjustment operation1Weight m of the strip1Satisfies the weight m-d1≤m1≤m+d2When n is greater than n1≥1， m>d1≥0，m>d2Not less than 0, the mechanism changes the first preset value of the system from m to m without stopping2When the weight adjustment operation is followed by n2Weight m of the strip1Satisfy the weight m2-d3≤m1≤m2+d4When n is greater than n2Not less than 1, the mechanism is suspended for operation, m2>d3≥0，m2>d4≥0；
Wherein d is1Is a second preset value of the system, d2Is a third preset value of the system, d3Is the fourth preset value of the system, d2The fifth preset value is the system. When in whole production process, when the adhesive tape of multiunit different weight need be cut, in order to guarantee that the adjustment of every adhesive tape reaches the standard, need guarantee that the actual weight of slitting equals in the interval of default or default, when adhesive tape quantity satisfies the quantity that needs produce simultaneously, the mechanism could pause the operation, has realized on automatic slitter setting and has surely got the function of the material of different target weight. Of course, a certain tolerance can be allowed for the strip, so that the system can set a preset value, or certainly not, a preset value, i.e. d1Is 0, d2Is 0, d3Is 0, d4Is 0; of courseThe user can also selectively set the numerical value according to the actual situation and requirements, wherein, d1、d2、d3、d4The value of (b) may be 0 to (m/50X2) g.
Further, when the mechanism does not stop, the first preset value of the system is changed from m to m2When the adhesive tape is cut, the mechanism adjusts the length L of the adhesive tape to be cut next time3To enter a weight adjustment operation of the adhesive tape, wherein the length adjustment of the adhesive tape satisfies the following formula: l is3＝m2/m1×L1；
Or when m-d5≤m1≤m+d6When the mechanism is not stopped, the first preset value of the system is changed from m to m2When the adhesive tape is cut, the mechanism adjusts the length L of the adhesive tape to be cut next time3The weight adjustment operation of the adhesive tape is started, and the length adjustment of the adhesive tape meets the following formula: l is3＝m2/m1×L1Wherein d is5As a sixth preset value of the system, d6Is a seventh preset value of the system, m>d5≥0，m>d6Is more than or equal to 0. When a plurality of groups of adhesive tapes with different weights need to be cut in the whole production process, the first preset value of the system needs to be changed for many times, at the moment, the next group of adhesive tapes can be adjusted by taking the adhesive tapes of the previous group as references, and certainly, the preset value of the system does not need to be set, namely d5Is 0, d6Is 0. Of course, the user can also selectively set the numerical value according to the actual situation and the requirement, wherein d5、d6The value of (b) may be 0 to (m/50X2) g.
Further, when the weight of the adhesive tape is m-d7≤m1≤m+d7When the weight of the next adhesive tape is not adjusted by the mechanism, the adhesive tape is cut according to the length of the previous adhesive tape, wherein d7Is an eighth preset value of the system, m>d7Is more than or equal to 0. Due to the characteristics of the materials, the overall thickness of the materials has a slight difference, the influence of the difference on the weight of the materials is within an acceptable range, an acceptable error range of a target value can be set in a program, and a system does not need a preset value, namely d7Is 0. Generally used sensors and systems have certain errors, so that the result has errors with theoretical values, in order to eliminate unnecessary actions caused by the errors, reasonable adjustment needs to be carried out on data, of course, a user can also selectively set numerical values according to actual conditions and requirements, wherein d7The value of (d) is generally the value required for counteracting the measurement error of the sensor, wherein the value of 0.1g can be selected, of course, the user can also selectively set the value according to the actual situation and requirement, preferably, d7≤d1And d is7≤d2。
Further, when the weight of the adhesive tape is m-d7≤m1≤m+d7When the rubber strip is used, the ratio of the length to the weight of the rubber strip is recorded as a coefficient z, namely z is L1/m1When the first preset value is not changed, the adhesive tape cut next time is made to be L1(ii) a When the first preset value m of the system is changed into m2When the adhesive tape is cut next time is L2＝m2Xz; when the weight of the rubber strips cut n times in succession meets m2-d7≤m1≤m2+d7When z is recorded as a standard factor, where n.gtoreq.1.

Wherein the upper limit of the weight of the qualified rubber strip cannot be higher than m + 30% m, and the lower limit cannot be lower than m-30% m.
Further, when the system has a standard factor z, and when the weight of the strip is m + 30% m<m1When is, or m1<m-30% m, the system calculates the length of the next strip, i.e. L, using a standard factor z2When the weight of the continuous n rubber strips meets m +30 percent m<m1When is, or m1<When m is 30 percent of m, deleting the standard coefficient z, giving an alarm by the system, or directly initializing, and carrying out the operation again from the first step, wherein n is more than or equal to 2; when the system has no standard factor z and when the weight of the strip is m + 30% m<m1When is, or m1<When m is 30 percent m, the system alarms, or is directly initialized and is operated again from the first step;
when the weight of the rubber strip is m + d7≤m1When m is less than or equal to m + 30%, or m is less than or equal to m-30%1≤m-d7The mechanism then performs a weight adjustment operation. When the error range of the target value is too large, the system judges that the strip cutting is unqualified, and the system does not establish a coefficient, the system alarms or directly initializes, and the operation is carried out again from the first step; wherein the upper limit of the weight of the qualified rubber strip cannot be higher than m + 30% m, and the lower limit cannot be lower than m-30% m. When the weight of the cut strip does not meet the standard but is not much different, the weight of the cut strip can be adjusted in an adjusting mode, so that the next cut strip meets the standard.
Further, when the weight of the rubber strip satisfies m + 30% m<m1When is, or m1<m-30% m, before the system is initialized, if the weight of the continuous n adhesive tapes does not meet m + 30% m<m1When is, or m1<And when m-30% m is reached, the mechanism does not perform weight adjustment operation, and performs slitting according to the length of the previous strip, wherein n is more than or equal to 2, otherwise, the system is initialized and re-operated from the first step. Before the system is initialized, when the cutting is detected to be unqualified, whether a plurality of continuous cutting strips meet the standard are qualified cutting strips or not is checked before the cutting is unqualified, when the cutting strips are detected to be qualified, system identification is possibly wrong, the actual cutting strips meet the standard, in order to not influence the production efficiency, a mechanism does not carry out adjustment operation, the cutting strips are carried out according to the length of the previous cutting strip, otherwise, the system identification is not wrong, the system needs to be initialized, and the first step is operated again.
Further, when the mechanism is started again after being suspended, the mechanism calls a time compensation function to adjust the length L to be cut of the adhesive tape at the next time4To enter a weight adjustment operation of the strip, wherein the time compensation function is L4＝L1+ kt, t being the mechanism pause time, k being the coefficient, t taking the value 0<t≤t1，t1The time required for the mechanism to pause until the adhesive tape does not shrink any more, when the pause time of the mechanism is longer than the time required for the mechanism to pause until the adhesive tape does not shrink any more, the value of t is t1The coefficient k is calculated by testing, k is (m)1-m3)×L1/(m3×t)，m3The weight of the rubber strip cut by the mechanism when the mechanism is restarted after being suspended in the testing process. When the mechanism is halted and then is cut again, materials such as rubber have the characteristic of contractibility, the material shrinkage can cause the blank to be inaccurate, a method of a time compensation value can be set, the distance compensation is carried out on the materials waiting for different times, a time compensation function can be obtained according to the rule in the actual production process, the feeding distance is not required to be adjusted again manually by applying the time compensation function, the material waste is avoided, the working efficiency and the adjusting precision are increased, the manual intervention is reduced, the operation is convenient, and the quantity of bad materials cut again after the machine is stopped is reduced.
