The specific embodiment
Fig. 1～Fig. 4 represents the mechanical structure of the creel device 1 of V font.In Fig. 1～Fig. 4, in order to support a plurality of yarn bodies 2 that supply, creel device 1 has the frame 3 with plane finding V font, and the yarn body framework 3b that supplies that is installed on these frames 3 possesses a plurality of support component 3a that laterally are set up in parallel that longitudinally reach.According to illustrated embodiment, support component 3a become whenever classify 10 layers longitudinally as, along transversely arranged N row, total can support 10 * N confession yarn body 2.Being configured in respect to adding up to 10 * N the position that support component 3a is suitable of the required quantity of warping for yarn body 2.At this moment, add up to whole supports of 10 * N support component 3a for yarn body 2.
, merged through after each yarn break sensor 9 of corresponding setting with each support component 3a from the many warp thread 4 of all drawing for yarn body 2, become the sheet of a regulation fabric width by reed 5.The warp thread 4 of this sheet is wound onto the volume of coiler device on axle through a plurality of guide rollers 6.
And the Yarn break checkout gear 10 of creel device 1 also possesses a plurality of controllers 11 and central processing unit 12 except having a plurality of yarn break sensors 9.Yarn break sensor 9 is provided with corresponding to each support component 3a, when from be supported on each support component 3a for warp thread 4 broken yarns of yarn body 2 time, produce the broken yarn signal.Controller 11 is provided with N for each row corresponding to support component 3a, and accepts the signal from 10 yarn break sensors 9 of each row.In addition, central processing unit 12 is connected with N controller 11 and monitors broken yarn in creel device 1 integral body.
Below, Fig. 5 represents the annexation that yarn break sensor 9, a N controller 11 and central processing unit 12 are mutual.In Fig. 5, #1, #2 ..., each controller 11 of #N comprises input port 15, output port 18, control part 16 and storage part 17.
In addition, central processing unit 12 and each controller 11 utilize second conveyer line 14 to be connected by bus, with second conveyer line 14 as the shared signal drive access, the signal of central processing unit 12 be input to side by side # 1, #2 ..., #N controller 11 input port 15.
Like this, except passing through first conveyer line 13 from the signal of central processing unit 12 or upstream side controller 11 and the signal from second conveyer line 14, input port 15 can also be imported the signal from 10 yarn break sensors 9 of each row side by side.In addition, the output port 18 of each controller 11 also can be connected with central processing unit 12 buses with the other conveyer line 19 that is different from first conveyer line 13, second conveyer line 14.This other conveyer line 19 is to be used for transmitting the signal of information of the stop signal that for example is accompanied by broken yarn or expression break point of thread and the conveyer line that is provided with to central processing unit 12.
The control part 16 of each controller 11 have judgement by the signal output state of the central processing unit 12 of second conveyer line 14 whether presentation address set the function of pattern.And according to comprising corresponding to by the signal of first conveyer line 13 from the information of self address of 11 pairs of input ports of controller 15 output of central processing unit 12 or upstream side, control part 16 can be confirmed the address, simultaneously can be according to the information of the signal of this input, obtain signal message according to the computation rule of setting corresponding to the address of the controller 11 that continues in the downstream.Set-up and calculated rule in control part 16 for this reason.In addition, in this example, from the controller 11 of upstream side set successively address 1,2,3 ..., N.Therefore, with regard to the computation rule on being set at control part 16, be set at 1, set rule (computation rule=+ 1) simultaneously its addition as calculated value.The address setting pattern is that the setting action of address predetermined timing such as when the power connection of device is carried out.
In addition, it is not position with respect to central processing unit 12 that above-mentioned what is called " upstream " reaches " downstream ", the just upstream on the direction of transfer of the signal of first conveyer line, 13 outputs, the meaning in downstream of employing.In addition, about each control part 16, above-mentioned " controller 11 of central processing unit 12 or upstream side ", mean according to comprising corresponding to from the information signal of self address of the central processing unit 12 that becomes upstream side and identification address for #1 controller 11, for #2 ..., each controller 11 of #N mean according to comprise corresponding to from #1, the #2 of a upstream side ..., self address information signal of #N-1 controller 11 and identification address.Therefore, can be described as the signal output unit (central processing unit 12 and controller 11) of a upstream side,
Can be the spike train signal that has corresponding to the umber of pulse of the address of the controller 11 of object output above-mentioned in addition " comprising the signal corresponding to the information of address ".That is, will be from central processing unit 12 to the signal of first conveyer line 13 output as the spike train signal, the included umber of pulse of this spike train signal can be the umber of pulse corresponding to the address that should set.And this moment, utilize the included umber of pulse of control part 16 these spike train signals of counting, the address of each controller 11 identification self.Therefore, each controller 11 (control part 16) has not shown counter.
The sequence of movement of Fig. 6 presentation address automatic setting.In Fig. 6, when the power supply of engaging means, the action (START) of central processing unit 12 start address automatic settings at first in step 1, is judged the output state (address setting pattern) of the signal of second conveyer line 14.Specifically, this judged result for example is the signal output state of second conveyer line 14 when being ON, enters next procedure 2, and each controller 11 is set at ON with the setting pattern, and controller 11 is set to other patterns when for OFF.
About address setting, when the output state of the signal of second conveyer line 14 is OFF, enter step 10, each controller 11 is set at OFF with the setting pattern, and pattern (END) is set in the end address.The signal output state ONOFF of certain second conveyer line 14 also can be with above-mentioned opposite.And in illustrated example, second conveyer line 14 that is connected with input port 15 buses of each controller 11 is one, but also can be two, utilizes the combination of the signal output state (ON or OFF) of these two second conveyer lines 14 can set a plurality of patterns.
In step 2, when address setting pattern is set to ON, in next procedure 3, address stored (counter) till each controller 11 is reset at this moment, Counter Value is made as 0, and the output of wait from the signal of the controller 11 of central processing unit 12 that transmits by first conveyer line 13 or upstream side is prepared in standby.
After this, #1 controller 11 outputs of central processing unit 12 by the upstream side of 13 pairs of first conveyer lines comprise the information signal corresponding to its address, promptly corresponding to the spike train signal of the address of #1 controller 11.In addition, in this example, the spike train signal by 13 outputs of this first conveyer line comprises the pulse with the consistent quantity in address of the controller 11 of its object output.In addition, in this example, as mentioned above with #1, #2 ..., each controller 11 of #N the address from upstream side be made as in order # 1, #2 ..., #N.Therefore, the signal from 11 outputs of 12 pairs of #1 controllers of central processing unit is the spike train signal of umber of pulse 1.
In following step 4, the input that #1 controller 11 is judged from the spike train signal of central processing unit 12.That is, for the detection of whether having carried out the rising of pulse, in the occasion (during NO) of not confirming the detection that pulse is risen, continuous alert status prepares to wait for the spike train signal from central processing unit 12.In addition, the occasion (during YES) having confirmed the detection that pulse is risen moves on to next procedure 5, in step 5, on the count value 0 of the interior counter that is contained in control part 16+1.
Then, in step 6, confirm to be included in the action of the umber of pulse in the output spike train signal.Specifically, judge from the moment of the rising that detects pulse whether passed through official hour,,, enter step 7 in order whether to detect the affirmation of the rising of pulse once more at the occasion of not passing through the stipulated time (during NO).
In addition, the above-mentioned stipulated time is the time of reasonable time value of setting for according to the pulse period of spike train signal, and is configured to the time longer than the pulse period of spike train signal.Specifically, when for example the pulse period of spike train signal was 10msec, the afore mentioned rules time can be made as 20msec etc.Therefore, be 2 or above occasion in the included umber of pulse of spike train signal, through before the stipulated time, in step 7, reaffirm the rising of pulse, and return step 5 once more.
But, for #1 controller 11, owing to being 1, so even also can not detect the rising of next pulse through the stipulated time from the included umber of pulse of the spike train signal of central processing unit 12.Therefore, in step 6, be judged as and passed through the stipulated time (YES).The control part 16 of #1 controller is judged the end of output of handling 12 spike train signals from central authorities thus, enters step 8 simultaneously, and Counter Value 1 is hereto exported to storage part 17, and the address with #1 controller 11 in storage part 17 keeps as 1.
Then, in step 9, the control part 16 of #1 controller 11 is that umber of pulse is 1 and the aforementioned calculation rule according to the address information of the relevant signal of importing, obtain information (2), will comprise that by output port 18 the spike train signal of this information is that umber of pulse is input port 15 outputs to #2 controller 11 of 2 spike train signal corresponding to the address of the #2 controller 11 in downstream.In the moment of this end of output, #1 controller 11 judges that the address setting of self finishes, and ends address setting pattern, address setting release in step 10.
After this, each controller 11 and the above-mentioned #1 controller 11 in downstream are same, utilize the spike train signal of input to discern the address of oneself and store this address, then, obtain information according to the computation rule of setting, and controller 11 outputs of side downstream comprise the spike train signal of this information corresponding to the address of the subsequent control device 11 in downstream.So, can from upstream side downstream side automatically set the address of each controller 11 successively.
In addition, according to above-mentioned processing action, the #N controller 11 in downstream is by first conveyer line 13, to the spike train signal of central processing unit 12 output umber of pulse N+1.At this moment, central processing unit 12 can have the function of the spike train signal that judgement returns from #N controller 11, from the initial spike train signal of exporting to #1 controller 11 at the appointed time, can judge the spike train signal of whether having imported above-mentioned umber of pulse N+1 from #N controller 11 constantly.
If, any one controller 11 occurs unusual, or when in the processing of relevant above-mentioned address setting, having produced miscount or mistake in computation, following situation can appear, promptly, in the above-mentioned stipulated time not to central processing unit 12 input signals, even or imported signal at the appointed time, this umber of pulse is also few.At this moment, central processing unit 12 is the action of executive address setting once more, or makes the operator learn this order with alarm or warning demonstration.When being simple processing mistake can carry out the possibility that normal address is set owing to have by carrying out once more, so also once more executive address set action, however when becoming equal state, also can export alarm.
The present invention is not limited to the foregoing description, also can modification implements the content of the foregoing description.In the above-described embodiments, be will be corresponding to the information of the included address of signal umber of pulse as the spike train signal, but the present invention is not limited to this, for example, also can be impulse amplitude (rising to the time of decline from pulse) or pulse period (rising to the time that second pulse risen) from the initial pulse of continuous two pulses.For example, can be set to: impulse amplitude (pulse spacing) is if 1/1000～9/1000msec address then: 1,10/1000～19/1000msec address then: 2 ... Deng.At this moment, the aforementioned calculation rule is set to relevant with the time, for example, for+10msec etc.In addition, be not limited to above-mentioned arbitrary occasion, as long as can also can be any type of signal with simple mode presentation address.
