In order to achieve the purpose, the invention adopts the following technical scheme:

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.

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.

When the mechanism is restarted after being suspended, the mechanism calls a time compensation function to adjust the length L to be cut by 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. Cutting again after the mechanism is suspended, because the materials such as rubber have the characteristic of contractibilityThe material shrinkage can cause the blank inaccurate, can set up the method of time compensation value, carry out the distance compensation to waiting the material of different times, and the time compensation function can obtain according to the law in the actual production process, and the pay-off distance need not artifical readjustment again of using the time compensation function, avoids causing the material extravagant, increases work efficiency and regulation precision, reduces the convenient operation of manual intervention, and the bad material quantity of the material cutting again after shutting down reduces.

In this embodiment, through weighing system, can obtain the weight of each material, handle the weight information of this material through the procedure to carry out proportion 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 manual intervention and has conveniently operated.
