Abstract
The invention relates to a method and a system for fixed-length shearing of unidirectional sheets. The method comprises the following steps: 1 a rolling wheel of a pulse encoder presses the unidirectional sheets and rolls with the forward-delivered unidirectional sheets, and the pulse encoder produces pulses; 2 a counter connected with the pulse encoder records the number of the pulses produced by the pulse encoder in an accumulating mode; 3 the counter compares the recorded pulse number with a set pulse number value, and the step 2 is re-performed if the recorded pulse number is smaller than the set pulse number value. A count value of the counter is reset and then the step 1 is re-performed if the recorded pulse number is equal to the set pulse number value, a control signal is sent to a plate shearing machine while the count value of the counter is reset, and the plate shearing machine shears the unidirectional sheets and stops working after finishing the action. By means of the method, the shearing length of the unidirectional sheets can be accurately controlled, and material waste is decreased.
Description
Technical field
The present invention relates to a kind of unidirectional sheet material cut-to-length method and system.
Background technology
Thermo-plastic planking's pre-preg carrying device is by opening up fibre, passing through PP plastic solution die head again, finally through supercooling rolling or shearing and obtain by glass fibre.Existing plate shearing machine is all generally that sheet material is put in plate shearing machine and sheared, if carried out like this in thermo-plastic planking's laminating apparatus, because sheet material is in running forward, if plate shearing machine does not move forward, can stop the operation of sheet material, make sheet material stress deformation, if out of service, shear again, can delay production again.And above-mentioned shearing be owing to cannot carrying out accurate Calculation and control to the size of sheet material, cause sheet material loss and artificial waste.
Summary of the invention
For above-mentioned technical problem, the object of this invention is to provide a kind of unidirectional sheet material cut-to-length method and system that can accurately control sheared length.
The technical scheme that realizes the object of the invention is as follows:
Unidirectional sheet material cut-to-length method, comprises the following steps:
Further, the length of the unidirectional sheet material that needs shearing is set on counter, this length gauge formula is:
The corresponding length of L=individual pulse * needed pulse number.
A system, comprises pulse coder, counter and plate shearing machine, and described pulse coder is provided with the roller contacting with unidirectional sheet material, and the output of pulse coder is connected with the input of counter, and the input of counter is electrically connected to plate shearing machine.
Further, described counter is the counter with amplifier, and amplifier is connected in the output of counter.
Adopted such scheme, the course of work of the present invention is: the roller of pulse coder is pressed on unidirectional sheet material along with going ahead of unidirectional sheet material rolled, be connected to the number of the pulse of the counter records generation on encoder, owing to being provided with the length (length computation is according to the needed pulse number of the corresponding length * of individual pulse) of the unidirectional sheet material that needs shearing on counter, after detecting the pulse that pulse coder sends, counter starts to count, until detect with the consistent output of value of final counting, be used for the signal of shearing, plate shearing machine is started working after receiving shear signal, unidirectional sheet material is sheared, unison counter zero clearing.When encoder next pulse comes, counter counts 1, repetitive cycling.The present invention is owing to having stipulated the sheet material length (being that length computation is according to the needed pulse number of the corresponding length * of individual pulse) of required shearing, like this, the accuracy of required length has obtained raising, after shearing, can not cause the waste of material, and because whole process is the process of automatically controlling, therefore, reduced artificial operation, be conducive to save production cost.
