Embodiment
As shown in Figure 1, the present invention includes pick-up unit 1 and control device 2; Wherein pick-up unit 1 is arranged on rope making machine, be provided with semiconductor laser, generate vertical with primacord fuse rope bar 3 and orthogonal XGuang road 5 and the Y light path 6 of intersecting, pick-up unit 1 is provided with for making the U-shaped that tested primacord fuse rope bar 3 passes detect groove, and primacord fuse rope bar 3 is positioned at the point of crossing of X-ray road 5 and Y light path 6; Control device 2 is provided with detected value signal input line 10 and connects the seal insert 7 being arranged on pick-up unit 1, and control device 2 is also provided with control signal output line 11; Described semiconductor laser detects tested primacord fuse rope bar 3 bar footpaths, photoelectric switching circuit electromotive force is changed, generating the data that store in detected value signal and control device compares, generate comparison data, start or stop thereby generate control signal control rope making machine, and control sound, the warning of light panalarm.
Rope making machine of the present invention is arranged between antiknock indoor, described control device and is arranged between antiknock outdoor.X-ray of the present invention road 5 is respectively equipped with the light path window 4 vertical with primacord fuse rope bar 3 with Y light path 6, and this light path window 4 is rectangle plane window.Light path window 4 of the present invention is provided with flat glass.Control device 2 of the present invention is provided with detected value for showing X-ray road 5 and Y light path 6 and the display window 8 of setup control value.Control device 2 of the present invention is provided with computer data interface 9.Control device 2 of the present invention is provided with power-supply device provides power supply to pick-up unit.
Design concept of the present invention:
The present invention provides 12V direct supply by control device to pick-up unit, the semiconductor laser of pick-up unit converts the parallel sweep laser beam of field scan to, in two light path windows of CongXGuang road and Y light path, penetrate, detected primacord fuse bar is positioned on the point of crossing of two light paths, due to the explosive load difference of primacord fuse, diameter is also different, the laser beam area blocking also just changes, the laser beam being blocked changes into after electric signal in receive window, transfer in control device outdoor between primacord fuse rope processed, compare with the average control value of setting after treatment, output control signal, the operation of this signal controlling rope making machine and stopping, simultaneously can control sound, light panalarm, realize the explosive load control of primacord fuse production run.Light path window is rectangle, and the length direction of rectangular window and the axis direction of tested primacord fuse are perpendicular, and window covers and do dustproof and waterproof processing with flat glass.
The present invention adopts laser variable-focus scan mode, the light flux variations of blocking light path that measurement causes through the variation of the primacord fuse bar overall diameter of detection light path.Due to external diameter and the explosive load relation in direct ratio of primacord fuse, the photoelectric switching circuit electromotive force receiving changes, by the corresponding relation of the comparison external diameter of primacord fuse and the primacord fuse explosive load of setting, thereby generation control signal, signal is controlled starting or stoping of rope making machine after amplifying, or sends sound and light signal.Via controller information after treatment can be downloaded printed report with computer, is convenient to follow the tracks of process.Double light path laser external diameter detection device of the present invention is arranged on explosive leading cable producing machine, the semi-manufacture rope bar of primacord fuse detects groove and passes from the U-shaped of pick-up unit, can not cause interference to the production operation process of primacord fuse rope processed, can not cause damage to detected primacord fuse.The control sampling spot spacing detecting is not more than 5mm, and measurable primacord fuse diameter is 0.1～20mm, can realize explosive load and detect continuity, there will not be undetected situation, and explosive load control accuracy reaches in 0.2g/m.Control device is arranged between the antiknock of primacord fuse outdoor, and operating personnel are in the outdoor setting that just can control parameter, and control device has carried out dustproof processing, meets the requirement of " industrial explosive material engineering design safety standard " GB50089-2007 standard.
Principle of work of the present invention:
The axis direction of primacord fuse, with to detect light path perpendicular, detects the overall diameter that the length of light path exceedes primacord fuse, and namely primacord fuse bar is completely in the sensing range in light path.In normal production run, because the dose of primacord fuse is stable, external diameter there will not be large variation, within the scope of the controlling value of measured value in prior setting, can not trigger control gear action.In the time there is explosive load variation, the overall diameter of primacord fuse just there will be corresponding change, the amount that primacord fuse pole spacing is lived light will change, the luminous flux that detects light arrival receive window also just changes, the electromotive force producing in the photoelectric commutator receiving changes (in the luminous flux interval range detecting, electromotive force and luminous flux relation in direct ratio that photoelectric tube produces), formation control signal after numerical value is processed, this signal intensity and predefined controlling value (mean value of the detected value of mutually perpendicular X and Y-direction) compare, judge that its value is whether in range of control, if in range of control, prove that the explosive load of primacord fuse is in normal eligible state, if exceeded control upper, lower limit, illustrate that primacord fuse explosive load is out of control, this timed unit is activated, start autoalarm and stop motion mechanism, stop producing, avoid produce primacord fuse because of explosive load cause defective.
After parking, complete through artificial treatment, output after qualified primacord fuse product rope section, then by this device be switched to detect state of a control both can enter normal production.
While it should be noted that the primacord fuse kind of producing different explosive loads, due to explosive load difference, the external diameter of primacord fuse is also different, need to set different controlling values to different product, to realize the control of explosive load.
Embodiment of the present invention is only the description that the preferred embodiment of the present invention is carried out; not design of the present invention and scope are limited; do not departing under the prerequisite of design philosophy of the present invention; various modification and improvement that in this area, engineering technical personnel make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents of request protection of the present invention, has all been documented in claims.
