Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2: in order to realize the effective detection to forme length, improve the yields of forme, reduce production costs, the utility model comprises the first conveying belt 5, the second conveying belt 8 and the 3rd conveying belt 12; The below that top between the first conveying belt 5 and the second conveying belt 8 arranges between the first blanking door 7, the first conveying belt 5 and the second conveying belt 8 is provided with ash can 9; The below that top between the second conveying belt 8 and the 3rd conveying belt 12 is provided with between the second blanking door 11, the second conveying belt 8 and the 3rd conveying belt 12 is provided with blanking table 13; Be provided with laser sensor 3 in described the first conveying belt 5 correspondences away from one end of the second conveying belt 8, the top of the first conveying belt 5 is provided with length coding device 4, described length coding device 4 is between laser sensor 3 and the first blanking door 7, laser sensor 3 and length coding device 4 are all connected with measurement processor 14, and measurement processor 14 is connected with the first blanking door 7 and the second blanking door 11.
Particularly, the outside, one end that described the first conveying belt 5 correspondences arrange laser sensor 3 is provided with cutting knife 2, and the outside of described cutting knife 2 is provided with conveying roller 1, and described cutting knife 2 is between conveying roller 1 and the first conveying belt 5.
Described length coding device 4 is connected with measurement processor 14 by high speed counting module 15.Described measurement processor 14 adopts PLC.The below of described the first conveying belt 5 is connected with ash can 9 by scrap web 6, and the below of the second conveying belt 8 is connected with blanking table 13 by blanking conveying belt 10.
In the utility model embodiment, length coding device 4, for resolution is the scrambler of 5000 pulses, can adopt the incremental encoder of Schneider XCC1912PS50KN.Consider vibration problems, correctness with data, not on the position that is arranged on belt drives wheel of length coding device 4, and be mounted in the top of the first conveying belt 5, the top of the first conveying belt 5 is platforms, be contained on platform and should not skid, also do not have the impact of the vibrations of belt drives wheel.
High speed counting module 15 is for the counting to length coding device 4, the corresponding umber of pulse of length coding device 4 feeds back to high speed counting module 15, high-speed counter module 15 obtains the length of forme according to umber of pulse, then send measurement processor 14 to, determined by measurement processor 14, whether meet dimensional requirement, just enter blanking table 13 if met, just enter ash can 9 if do not met.
The sensor that laser sensor 3 utilizes laser technology to measure.Laser sensor 3 is made up of laser instrument, laser detector and metering circuit.The advantage of laser sensor 4 is to realize contactless telemeasurement, and speed is fast, and precision is high, range is large, anti-light, electrical interference ability is strong etc. and when laser sensor 4 is worked, first by the pulse of Laser emission diode pair standard target Emission Lasers, after target reflection, laser is to all directions scattering.Part scattered light turns back to sensor receiver, after being received, is imaged onto on avalanche photodide by optical system.Avalanche photodide is the optical sensor that a kind of inside has enlarging function, and therefore it can detect extremely faint light signal, and is translated into corresponding electric signal.Laser sensor 3 can adopt existing conventional structure.
