Abstract
The invention discloses a penetrating type annular sensor. The penetrating type annular sensor comprises a plastic sleeve. A through cavity is formed in the plastic sleeve. An annular groove is formed in the outer wall of the front portion of the plastic sleeve. Multiple circles of varnished wires, insulated rubber tape and wave suction bands are wound in the annular groove. An external cable is connected to a detection plate. Taps of the multiple circles of varnished wires are connected to the detection plate. The penetrating type annular sensor can complete shortage gap detection for cigarettes in a cigarette packet in cooperation with a probe.
Description
Technical field
The present invention relates to probe device for detecting distance of travel field, be specially a kind of through type loop sensor.
Background technology
In automated production process, need to carry out quality testing to product, as outward appearance, weight, quantity etc.Aspect tobacco package, often use mechanical type probe in detecting device to detect a bear that lacks for tobacco bale.The loop sensor of detecting device inside is mainly for detection of the stroke of metal probe.To the technical requirement of loop sensor: when the stroke that penetrates loop sensor when probe is greater than 2mm, sensor just can sense that probe exists; When the stroke that penetrates sensor when probe is less than 1.5mm, sensor can not sense that probe exists, and accuracy of detection reaches 0.5mm.For existing loop sensor, when pressing close to sensor, probe just can sense the existence of probe, cannot accomplish that probe penetrates sensor and just can sense that probe exists, so cannot detector probe stroke.
Summary of the invention
The object of this invention is to provide a kind of through type loop sensor, to solve the problem that prior art loop sensor cannot detector probe stroke deficiency.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of through type loop sensor, it is characterized in that: comprise plastic casing, in plastic casing, be provided with straight-tube shape cavity, on the anterior outer tube wall of plastic casing, be provided with annular groove, in annular groove, be wound with multi-turn enameled wire, and multi-turn enameled wire has tap to draw from annular groove after being wrapped in annular groove, in annular groove, be also provided with the insulating tape being wrapped in outside multi-turn enameled wire, and be wrapped in the suction wavestrip of being made by absorbing material outside insulating tape, also include check-out console, on described check-out console, have access to external cable, on described tap access check-out console.
Described a kind of through type loop sensor, is characterized in that: the anterior outer tube wall of plastic casing is shaped to wide diameter portion, and described annular groove is arranged on wide diameter portion.
Beneficial effect of the present invention:
Through type loop sensor of the present invention can coordinate probe to complete the bear's detection that lacks to tobacco bale cigarette.Compared with existing loop sensor detection mode, in the present invention, when probe penetrates after the certain stroke of plastic casing cavity, sensor just can sense the existence of probe, thereby can measure probe stroke.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1.A kind of through type loop sensor, comprise plastic casing 1, in plastic casing 1, be provided with straight-tube shape cavity, on the anterior outer tube wall of plastic casing 1, be provided with annular groove, in annular groove, be wound with multi-turn enameled wire 2, and multi-turn enameled wire 2 has tap 7 to draw from annular groove after being wrapped in annular groove, in annular groove, be also provided with the insulating tape 3 being wrapped in outside multi-turn enameled wire 2, and be wrapped in the suction wavestrip 4 of being made by absorbing material outside insulating tape 3, also include check-out console 5, on check-out console 5, have access to external cable 6, tap 7 accesses on check-out console 5.The anterior outer tube wall of plastic casing 1 is shaped to wide diameter portion, and annular groove is arranged on wide diameter portion.
Check-out console be by the LC oscillator signal that affected by metal probe after amplification treatment circuit is processed, output low and high level judges that signal sends into upper computer control system.
Check-out console is comprised of LC oscillatory circuit and amplification treatment circuit two parts.The multi-turn enameled wire being wound around in plastic casing annular groove forms LC oscillatory circuit jointly as capacitor C on inductance L and check-out console, and two taps of multi-turn enameled wire are welded on capacitor C two ends.Amplification treatment circuit is comprised of potentiometer R and metal detection special chip.
Detection principle is as follows: when in metal probe penetrates plastic casing, straight-tube shape cavity enters the electromagnetic field of LC oscillatory circuit generation, electromagnetic field can be at the inner eddy current that produces of metal probe.This eddy current reacts on LC oscillatory circuit, causes the amplitude attenuation of LC oscillator signal, and the power of amplitude attenuation is relevant with the stroke that metal probe enters cavity.The stroke intensity that more amplitude is decayed is larger, otherwise less.LC oscillatory extinction signal is sent into amplification treatment circuit, and when LC oscillator signal amplitude is less than the threshold value of metal detection special chip, metal detection special chip output high level signal, detects metal probe and exist; When LC oscillator signal amplitude is greater than the threshold value of metal detection special chip, metal detection special chip output low level signal, surveys and exists less than metal probe.Low and high level signal is sent into upper computer control system by external cable on check-out console.By the resistance of regulator potentiometer R, can adjust the threshold value of metal detection special chip.The resistance of potentiometer R is larger, and threshold value is higher.
In the present invention, sticking plaster material is processed into plastic casing 1.Enameled wire 2 is wound around a fixing turn in plastic casing 1 wire casing, winds two taps 7 of rear output.Wind after enameled wire 2, coil is wound around with insulating tape 3, and the suction wavestrip 4 made from absorbing material is wound around insulating tape 3.Two taps 7 are welded on check-out console 5.By two in 6 three cables of external cable, power to check-out console 5, the 3rd cable judges that by the low and high level of check-out console 5 signal is transported to upper computer control system, by regulating potentiometer resistance size on check-out console 5, while guaranteeing that stroke that probe 8 gos deep into sensor is greater than 2mm, sensor just can sense the existence of probe 8; While being less than 1.5mm, sensor sensing is less than the existence of probe 8.
