Description
Affiliated technical field
The present invention relates to a kind of watch-dog, particularly a kind of two-way detects split type roller running monitor.
Background technology
At present, known watch-dog adopts photoelectric sensor mostly.
Yet, existing optoelectronic switch complex structure, volume is too large, can't be installed on the roller of the extremely narrow Computerized flat knitting machine in space at all, this up to the present namely, though both at home and abroad the electrostatic interaction because of balata belt is easy to be wrapped with the braiding material on the roller transmission balata belt of all Computerized flat knitting machines, the basic reason that can't detect with existing optoelectronic switch.
Summary of the invention
Can't use at the roller of Computerized flat knitting machine the shortcoming and defect of existing optoelectronic switch technology in order to overcome existing watch-dog, be easy to be wrapped with the problem of braiding material on the roller transmission balata belt of domestic and international all Computerized flat knitting machines of solution because of the electrostatic interaction of balata belt, the invention provides a kind of two-way and detect split type roller running monitor.
The technical solution adopted for the present invention to solve the technical problems is: comprise luminescent device, sensitive device, signal amplification circuit, pulse signal radiating circuit, signal transformation circuit and signal output apparatus, and the transmitting probe of the two-way that is formed by above-mentioned parts, receiving transducer and the signal processing unit of two-way, the transmitting probe of described two-way, the receiving transducer of two-way link to each other with signal processing unit with electric wire.Its basic comprising adopts two schemes:
Scheme 1 described transmitting probe contains luminescent device, and described receiving transducer contains sensitive device, signal amplification circuit, and described signal processing unit contains pulse signal radiating circuit, signal transformation circuit and signal output apparatus.
Scheme 2 described transmitting probes contain luminescent device, pulse signal radiating circuit, and described receiving transducer contains sensitive device, signal amplification circuit, and described signal processing unit contains signal transformation circuit and signal output apparatus.
Described receiving transducer adopts metallic shield to process, and suppresses the external interference signal.
The invention has the beneficial effects as follows: energy effective monitoring roller emerged in operation: winding production material etc. occurs on the traction belts distortion perk on the roller, the aging fracture of belt, the belt; when the various improper phenomenon more than the appearance; the timely output electrical signals of watch-dog energy is to machine control unit; make and shut down and send warning on the mechanical horse; allow the workman in time fix a breakdown, resume production rapidly.
Description of drawings
Lower picture further specifies the present invention in conjunction with the accompanying drawings and embodiments.
[Fig. 1] is frame principle figure one of the present invention.
[Fig. 2] is frame principle figure two of the present invention.
[Fig. 3] is circuit theory diagrams of the present invention.
The specific embodiment
(mode 1 of enforcement)
Below, two-way of the present invention is detected split type roller running monitor illustrate with reference to drawing.Fig. 1 is the frame principle figure one of mode 1 of the invention process, and Fig. 3 is circuit theory diagrams of the present invention.
The present invention adopts optoelectronic switch to detect Computerized flat knitting machine top roller transmission balata belt and whether is wrapped with the braiding material, is not to be existing optoelectronic switch migrating on Application Areas, but a kind of application of brand new technical.The present invention divides emission probe, receiving transducer and signal processing unit three parts in shape, and wherein transmitting probe, receiving transducer have two to (also can be a pair of, concrete quantity can be decided according to actual conditions).Luminescent device is installed on the transmitting probe, sensitive device and signal amplification circuit are housed on the receiving transducer, transmitting probe, receiving transducer link to each other with signal processing unit by lead-in wire, there are pulse signal generator, signal transformation circuit and signal output apparatus in signal processing unit inside, because the signal processing unit internal circuit is more, more complicated, the assembling volume is larger, (be installed in the unrestricted space of machine location) so put behind, link to each other with transmitting probe, receiving transducer with electric wire.And the probe segment circuit seldom, and the assembling small volume can be installed in the little place of locational space, so just solved well the problem of installing by split type mechanism scheme.
Identical A, B two-way are in parallel to be consisted of because the present invention has, and the operation principle of its two-way is identical, so we only analyze one the tunnel and get final product, and another road is omitted and narrated.
Transmitting probe only contains luminescent device.The pulse signal radiating circuit that its source that transmits is signal processing unit inside (seeing accompanying drawing 3): produce pulse signal by R6a, IC1Da, D2a, R7a, C4a, consist of signal transmission circuit by R8a, D3a, T4a, R9a, R10a, C5a.Wherein pulse signal is by the output output high-low level pulse square wave signal of IC1Da, go T4a conducting and the cut-off of control signal radiating circuit, by rational R6a, the R7a value changes dutycycle, R8a, C5a consists of energy-storage function, D3a just can obtain larger emission current of moment like this, cycle and dutycycle by the appropriate design pulse signal, make luminescent device in the course of the work, launch time is extremely short, and the time of stopping paying out is longer, this just so that luminescent device in the little situation of average operating current, the operating current of T-time can be larger, so just can effectively improve transmitting range, allow the watch-dog be that roller in the 2M scope carries out the effective scanning monitoring to length.
At receiving unit, consist of signal amplification circuit by D1a, T1a, R1a, C1a, R2a, R3a, T2a, because signal amplification factor is large, be easy to be subject to the external interference effect of signals, for avoiding this bad phenomenon, should adopt the method for metallic shield or shielding line bonding to sensitive device, signal amplification circuit, suppress the external interference signal.
Amplifying signal is sent to signal shaping again and processes, and signal transformation circuit is made of C2a, R4a, T3a, R5a, C3a, IC1Aa, and the purpose of signal transformation circuit is that the noise signal that receiving unit is sent here is transformed into stable high-low level.Give again at last signal output apparatus, remove the control utmost point of power ratio control switching tube by the high-low level signal, thereby the conducting of power ratio control switching tube and closing reaches the control purpose.
(mode 2 of enforcement)
Below, two-way of the present invention being detected split type roller running monitor illustrate with reference to drawing, Fig. 2 is frame principle figure two of the invention process, Fig. 3 is circuit theory diagrams of the present invention.
Its principle is with embodiment 1, and just the transmitting probe of embodiment 1 contains luminescent device, and the pulse signal radiating circuit is placed on the signal processing unit the inside.And the transmitting probe of embodiment 2 contains luminescent device and pulse signal radiating circuit, and the signal processing unit of embodiment 2 is compared with the signal processing unit of embodiment 1, has saved the pulse signal radiating circuit.
