Abstract
The invention discloses a non-contact on-line bar length measuring device and method. The device includes conveying rollers, a detection element I, a detection element II, and a PLC module, the detection element I and the detection element II are respectively arranged at the two sides of the conveying rollers, and the PLC module is connected with the detection element I and the detection element II. The running speed of a bar on the rollers is obtained by calculating the time of the head or tail part of the bar passing through the two detection elements and the distance between the two detection elements, and the time of the head part and the tail part of the bar passing through the detection element I or the detection element II and the speed obtained through the calculation are multiplied to obtain the length of the bar. The device can realize the on-line length measurement of bars, the method is simple, the operation is easy, the measurement accuracy is high, and the manufacturing cost is low.
Description
Technical field
The invention belongs to field of metallurgical mechanical equipment, is a kind of device of non-contact type on-line measurement web length.
Background technology
Usually need to measure its length when producing web.And existing length-measuring appliance is generally web axial advancement on rollgang, circumference is motionless, is measured by the number of turns that contact measurement wheel rotates with it, and for skew table, the existing axially-movable of the roundwood transported has circumferential movement again, cannot use contact type measurement wheel measurement length.
Summary of the invention
The object of this invention is to provide a kind of device and method of non-contact type on-line measurement web length, realize carrying out accurate linear measure longimetry online to web.
For achieving the above object, the technical solution used in the present invention is:
A kind of device of non-contact type on-line measurement web length, at least comprise rollgang, detecting element I, detecting element II and PLC module, described detecting element I and detecting element II is separately positioned on the both sides of several delivery tracks, described PLC module is connected with detecting element I and detecting element II respectively, and described rollgang is straight roller-way or cross roll road.
A method for non-contact type on-line measurement web length, utilizes said apparatus to measure, comprises the steps:
1) when web head makes to start timing during detecting element I sender; When web head makes detecting element II sender, timing terminates, and now records the time that web head moves to detecting element II from detecting element I to be designated as t1; Distance between detecting element I and detecting element II is designated as S, calculates web head translational speed V1=S/t1;
2) web afterbody translational speed V2=S/t2 is in like manner calculated according to said method;
3) data drawn according to above-mentioned steps calculate web translational speed V=(V1+V2)/2;
4) detecting element I from sender be designated as t3 to afterbody total length through the time that detecting element I is used from head to stopping time of sender to be web;
5) according to step 4) in like manner can record web total length and be designated as t4 through the time that detecting element II is used;
6) the run duration t=(t3+t4)/2 of web total length, can calculate web total length L=Vt.
The invention has the beneficial effects as follows: utilize this device can realize carrying out linear measure longimetry online to web, and do not need to contact measured object, cost of manufacture is low; Measuring method is simple, easy to operate and measuring accuracy is high.
Accompanying drawing illustrates:
Fig. 1 is a kind of exemplary construction schematic diagram of the present invention.
In figure: 1, rollgang, 2, detecting element I, 3, detecting element II, 4, PLC module, 5, web.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As shown in Figure 1, a kind of device of non-contact type on-line measurement web length, at least comprise rollgang 1, detecting element I2, detecting element II3 and PLC module 4, described detecting element I2 and detecting element II3 is separately positioned on the both sides of several delivery tracks 1, described PLC module 4 is connected with detecting element I2 and detecting element II3 respectively, and described rollgang 1 is straight roller-way or cross roll road.
A method for non-contact type on-line measurement web length, utilizes said apparatus to measure, comprises the steps:
1) when web 5 head makes to start timing during detecting element I2 sender; When web head makes detecting element II3 sender, timing terminates, and now records the time that web 5 head moves to detecting element II3 from detecting element I2 to be designated as t1; Distance between detecting element I2 and detecting element II3 is designated as S, calculates web head translational speed V1=S/t1;
2) web 5 afterbody translational speed V2=S/t2 is in like manner calculated according to said method;
3) data drawn according to above-mentioned steps calculate web 5 translational speed V=(V1+V2)/2;
4) detecting element I2 from sender be designated as t3 to afterbody total length through the time that detecting element I2 is used from head to stopping time of sender to be web 5;
5) according to step 4) in like manner can record web total length and be designated as t4 through the time that detecting element II3 is used;
6) the run duration t=(t3+t4)/2 of web total length, can calculate web total length L=Vt.
Obviously, embodiment described above is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
