Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but does not form any restriction of the present utility model.
As shown in Figure 1, for achieving the above object, the technical solution of the utility model is: the online length measuring system of a kind of contactless sheet material, mainly comprise detection flip flop equipment, image collecting device, image processing apparatus, described detection flip flop equipment is connected with image collecting device, described image collecting device is connected with image processing apparatus, described detection flip flop equipment mainly comprises two pairs of laser-correlation sensors 1, 2, two proximity switches 3, 4, scm managing system 5, described scm managing system 5 and laser-correlation sensor 1, 2, proximity switch 3, 4 are connected, gather laser-correlation sensor 1, 2 and proximity switch 3, the state of 4, described laser-correlation sensor 1, 2 adopt measurement light thinner, export the sensor for positive-negative-positive, additional cooling, dust cover, distance between two laser-correlation sensors is set to 5.6m, laser-correlation sensor 1 is as far as possible near fixed size scissors, distance is 0.5m.As shown in Figure 2, the light making laser-correlation sensor emission go out during installation passes between two rollers, and the oblique angle between light and sheet material is less than 90 degree, laser-correlation sensor is in ability that the dust-proof and high temperature-proof of system can be improved in sheet material both sides; Proximity switch 3,4 is contained in starting point and the terminal of on-the-spot shear action, to detect the shear action in production run; Industrial camera 6 adopts has the technical grade web camera that I/O triggers candid photograph function, additional heat insulation, dust cover, adjusts camera view in the place from more than fixed size scissors 6m during installation.
Described image collecting device forms primarily of the web camera 6 with I/O triggering candid photograph function demarcated, described web camera 6 captures the starting point coordinate of sheet material terminal image and sheet material according to the change of laser-correlation sensor 1,2 state, and be sent to image processing apparatus by RS485 bus, described image processing apparatus forms primarily of computing machine 7, described computing machine 7 pairs of sheet material terminal images carry out rim detection, determine the actual coordinate of sheet material terminal, deduct corresponding starting point coordinate, calculate panel length and carry out voice broadcast.
As shown in Figure 3, according to the quality of panel length, produced on-site mode and sheet material, the state of laser-correlation sensor can be classified as following 6 types in process of production, take fixed size scissors as true origin.(short slab ﹤ 6.1m, long slab >=6.1m)
A: an independent block length plate
Laser-correlation sensor (1,2) is all trigger industrial camera when shear signal being detected after high level to capture, and sends starting point coordinate S1; Trigger industrial camera when not having shear signal the falling edge of laser-correlation sensor (1) to be detected to capture, and send starting point coordinate S2.
B: independent one piece of short slab
Laser-correlation sensor (1) is high level, laser-correlation sensor (2) for cutoff signal or laser-correlation sensor (1) detected after low level falling edge after, wait for that the falling edge of laser-correlation sensor (2) triggers industrial camera when arriving and captures and send starting point coordinate S3.
C: last block length plate does not also carry out again one piece of short slab by laser-correlation sensor (2)
Laser-correlation sensor (1,2) is all detect after high level that the falling edge of laser-correlation sensor (1) or shear signal then wait for that second negative edge of laser-correlation sensor (2) triggers candid photograph when arriving, and sends starting point coordinate S3.
