Abstract
The invention provides a device and method for measuring the thicknesses of high-speed motion polyurethane foam strip sheets. A thickness measurement instrument is not available in an existing production process of soft polyurethane foam strip sheets, timely measurement and processing cannot be conducted when the thicknesses are not uniform, and sub-quality products are massively generated when the thickness problem is found in finished products. The device comprises a support (5), a high-accuracy sensor and a signal converter (3), the high-accuracy sensor (2) and a high-point defining device (1) are installed on the support, the high-point defining device makes contact with the surface of one running strip sheet, the signal converter is connected with a PLC control interface (4), and the high-accuracy sensor is connected with the high-point defining device. The device and method are used for measuring the thicknesses of the soft polyurethane foam strip sheets.
Description
technical field:
the present invention relates to a kind of soft sheet material measurer for thickness and measuring method, be specifically related to the rectangular sheet material measurer for thickness of high-speed motion isocyanurate foam and measuring method.
background technology:
existing thickness measuring instrument has two kinds in the market: a kind of is static measurement instrument, i.e. the static placement of measured object, then uses apparatus measures, has contact and contactless two kinds of measuring methods.Another kind is kinetic measurement instrument, i.e., during rectangular sheet material tangential movement, by the variation in thickness of sheet material each point in apparatus measures direction of motion, be all contactless substantially.But its measured sheet material is all the material with regular smooth surface.As thin metal plate, plastic foil etc.And the surface of the rectangular sheet material of flexible polyurethane foams is such: the rectangular sheet surface of so-called flexible polyurethane foams is comprised of the tiny abscess skeleton hair stubble much cutting off, its surface is all the depression pitting of different depth, and traditional thickness measuring instrument can not carry out Measurement accuracy.Sum up traditional kinetic measurement instrument and have following some deficiency to measuring the rectangular sheet material of flexible polyurethane foams:
1, the surface that does not have instrument to be comprised of the tiny abscess skeleton hair stubble much cutting off the surface of the rectangular sheet material of flexible polyurethane foams is measured, and this surface is can not measure actual thickness numerical value with existing kinetic measurement instrument;
2, the rectangular sheet material thickness deviation of the flexible polyurethane foams standard of formulating for some high standard industries, traditional sensor accuracy is low, can not effectively reflect and control;
3, traditional measuring method can not comprehensively be measured the vertical and horizontal of rectangular sheet material, can not get real thickness.
, traditional surveying instrument easily produces fluctuation and vibration under product high-speed motion, can cause data deviation and foam infringement.
, traditional surveying instrument can not long-term follow record and report to the police and stop, the loss percentage of sheet material is high.
, traditional thickness measuring instrument complex structure, be not easy to operation, maintenance and repair cost is high.
summary of the invention:
the object of this invention is to provide a kind of soft sheet material measurer for thickness and measuring method, the rectangular sheet material measurer for thickness of high-speed motion isocyanurate foam and measuring method are specifically provided.
above-mentioned object realizes by following technical scheme:
the rectangular sheet material measurer for thickness of a kind of high-speed motion isocyanurate foam, its composition comprises: support, described support is provided with one group of high-precision sensor, one group high point defines device, described height point defines device and is arranged on operating rectangular sheet material surface, described high-precision sensor is connected with signal converter, described signal converter is connected with PLC, and described high-precision sensor defines device with high point and is connected.
the rectangular sheet material method for measuring thickness of high-speed motion isocyanurate foam, the method comprises the steps:
(1) high-precision sensor described in and described height point define device and are placed on the active section support between rectangular sheet material cutting and package, described high-precision sensor and described signal converter and described PLC connect, and start the described rectangular sheet material measurer for thickness of high-speed motion isocyanurate foam;
(2) start after the described rectangular sheet material measurer for thickness of high-speed motion isocyanurate foam, described height point defines device described high-precision sensor is measured and fed back to the height on the tiny abscess cut-out of the rectangular sheet material of isocyanurate foam back skeleton hair stubble top;
(3) described high-precision sensor defines the signal converter described in sending to together with device feedback data measurement data and high point, described signal converter is changed and is sent to described PLC the signal receiving and controls in interface internal controller, described PLC controls interface the variable signal of travelling speed and line duration is processed and record, and draws change curve;
(4), while finding that there is the situation over KB limit in measuring, the rectangular sheet material measurer for thickness of described high-speed motion isocyanurate foam can quit work by automatic alarm, just can continue production after staff fixes a breakdown.
beneficial effect of the present invention:
1, the height point of developing in the present invention defines device and exactly the position data on skeleton hair stubble (surface of the rectangular sheet material of flexible polyurethane foams is actual is the tiny skeleton hair stubble after foam bubble pore structure is cut off by cutter) top is gathered and feed back to high-precision sensor, and it is not subject to the impact of those intensive numerous depression pittings in actual foam sheet surface at all.Therefore it can guarantee to reflect steadily in the long term the real surface situation of sheet material, and failure rate is reduced to zero.
, sensor accuracy of the present invention is very high, for existing those high-level sheet material demand industries, as automobile, the industries such as electronics, the sheet thickness tolerance standard that they are formulated, this sensor all covers, therefore can effectively reflect and control.
, height point that the present invention developed and adopted defines device and sensor is uniformly distributed on the transversal of rectangular sheet material direction of motion, can measure the thickness on the vertical and horizontal of rectangular sheet material comprehensively, can obtain the actual thickness situation of whole rectangular sheet material.
, thickness measuring instrument of the present invention can carry out static measurement, also can when rectangular sheet material carries out the motion of friction speed, measure, especially, when high-speed motion, also can guarantee Measurement accuracy, can not produce any fluctuation and vibration, can not cause damage to foam sheet yet.
, data processing of the present invention and on-line monitoring system complete, can long-term follow record, again can be when the value that transfinites occurs, and alarm stops, and corrects a mistake, handling failure, drops to minimum by loss.
, thickness measuring instrument sound construction of the present invention is simple and direct, convenient operation, maintenance and repair cost is extremely low, little power consumption, expense is low, safe and reliable.If improved a little, can use by spread.As at nonwoven fabrics, fluffy cotton, textile, carpet, netted rectangular sheet material, that the rectangular sheet material of glass fibre and the rectangular sheet material of asbestos etc. have is irregular, the online thickness measure of the product on unsmooth surface and control enterprising enforcement and use.
