Abstract
This invention is about a reciprocating motion control method for printing equipment. The non-printing time composed of a retreat time of a hammer bank when many lines are fed and a restart time of the reciprocating motion mechanism is measured. If the non-printing time is longer than a paper feed time, say by 10%, a correction feedback control is performed on the retreat time. That is, the retreat time is reduced during the next feeding of many lines. On the other hand, if the non-printing time is shorter than the paper feed time, the printing is conserved during a half of the period for feeding many lines and resumed during the second half of the period after paper feed. The printing quality defect and printing speed slowdown can be prevented when many lines are fed with this control.
Description
The present invention relates to a kind of printing equipment that is provided with the reciprocating mechanism of tubular linear motor driven, more particularly, be the method for controlling reciprocation of the reciprocating mechanism portion of linear motor.
A kind of reciprocating mechanism that is provided with tubular linear motor driven, the typing apparatus that the have a plurality of typewriting elements tup group (hammer-bank) of (point type typewriting hammer etc.) is moved back and forth by this reciprocating mechanism are known.Fig. 1 is an example of the linear motor reciprocating mechanism of this typing apparatus of expression.
In typing apparatus shown in Figure 1, the tup group 10 of adorning a plurality of typewriting elements is bearing on the Direct Action Type bearing 12 reciprocating action on the axis of guide 11.Linear motor portion 20 as the power source of reciprocating action is made of coil 21 and magnet 24 at least, and coil 21 has counter-rotating coil 22 and constant speed coil 23.Tup group 10 is connected with synchronous belt 31 with coil 21.Constitute reversing device portion 30 by synchronous belt 31 and 1 pair of timing belt pulley 32, the power of useable linear motor part 20 outputs moves back and forth tup group 10.
The counter-rotating reciprocating action of tup group 10 and coil 21 is controlled according to predetermined reciprocating rate curve.In order to carry out such control, installation site detecting sensor 50 on the position on the way that tup group 10 moves.Signal according to position-detection sensor 50 outputs is obtained the position of tup group 10 and the reciprocating motion speed of tup group 10.In order to control the counter-rotating reciprocating action of tup group 10 and coil 21, be provided with and move back and forth control circuit 60 and reciprocating motion drive circuit 70, the former changes the current value by coil 21, and the latter makes electric current pass through coil 21.
Typing paper is to load onto facing to tup group 10, is carried by the paper advance mechanism that does not have expression among the figure.Then in tup group 10 reciprocating action processes, drive towards typing paper, typewrite thus by inked ribbon, the element of will typewriting.
Below, the velocity wave form of open-wire line motor reciprocating mechanism with reference to Fig. 2.
Among Fig. 2, the reciprocating motion of tup group 10 is moved shown in velocity wave form, is divided between the reversal zone and the constant speed interval.Between the reversal zone, electric current flows through counter-rotating coil 22, slow down control and acceleration control; In the constant speed interval, electric current flows through constant speed coil 23, carries out the constant speed control of moving with certain speed.
In above-mentioned control, between the reversal zone, carry out paper feeding, carry out the control of reversing time, so that can finish synchronously to begin next time printing, can print with the highest efficient thus with paper feeding.At this moment, generally be the paper feeding of carrying out 1 line feed between the reversal zone.
When the printing that comprises 2 line feed above (below be called " changing multirow ") enters a new line, in order to improve print speed, the control that typing apparatus possessed of developing can be in the paper feeding of carrying out multirow, make tup group 10 in arbitrary region, wait to keep away, and can when paper feeding finishes, begin to print the process that moves back and forth of recovering common like that (above-mentioned a series of control be called as change the multirow Synchronization Control).
Fig. 3 represents to have the velocity wave form of the linear motor reciprocating mechanism that changes the multirow Synchronization Control.
Change under the occasion of multirow implementing, after constant speed control, to change into and change the multirow Synchronization Control, in changing multirow Synchronization Control interval, to carry out the paper feeding of multirow, can when paper feeding finishes, begin to print to restart like that and move back and forth.At this moment, under the occasion that many, the paper feeding time of line feed number is grown, as shown in Figure 3, the reciprocating motion of tup group 10 is restarted after in a single day stopping, and returns to the common process that moves back and forth.Under the occasion few at the line feed number, that paper feeding time is short, be not stop to move back and forth action just to return to the common process that moves back and forth sometimes.
Fig. 4 shows the appearance of this a succession of reciprocating motion action.
Begin to change the multirow Synchronization Control from changing multirow printing end position a before.Changing after the multirow Synchronization Control begins,, returning to the common process that moves back and forth afterwards, reciprocating mechanism being started once more through the required time of predetermined every kind of paper feeding amount (below be called " time to be kept away ").Represent to make it to return to the starting position of the control of the common process that moves back and forth with b, promptly restart the position.When restarting, arrive next printing initiating position C, reciprocating mechanism begins to print.At this moment call the time of restarting from restarting the time of position b till next printing initiating position C.The paper feeding of changing multirow be the time to be kept away add the time of restarting during this period of time in, promptly carry out in the time outside printing.
Though Fig. 4 has represented near carry out paper feeding reciprocating amplitude right-hand member example, also is same when carrying out paper feeding near the amplitude left end or at two ends.Though and Fig. 4 represented that tup group 10 avoids inboard and example that carry out standby from end between print zone, avoids from end between print zone in the tup group and also carries out same control when standby is carried out in the outside or end position is avoided standby between print zone.
In changing the multirow Synchronization Control, the time to be kept away of the predefined every kind of amount of changing one's profession is to deduct the time of restarting and try to achieve from paper feeding time.This be based on tup group 10 from restart position b, through arriving the supposition of printing initiating position C after stipulated time (restarting the time).Promptly, former changing be based in the multirow Synchronization Control and wait that the time of keeping away is predetermined fixed value according to every kind of paper feeding amount, usually is this certain prerequisite and control and move back and forth action from restarting time that position b arrives printing initiating position c.Therefore,, before paper feeding finishes, begin printing sometimes, cause that print quality is bad by variations in temperature or be added to the load change in the reciprocating mechanism portion and the time of restarting is produced under the occasion of change.
And be provided with the counter-rotating boosting mechanism in the structure of reciprocating device portion, and it applies converse rotating force to moving back and forth of tup group 10, and the deviation of this counter-rotating active force also can make the time of restarting produce change sometimes, causes that above-mentioned print quality is bad.
In addition, if become very long,, so just have the problem that reduces print speed even, still can before paper feeding finishes, not begin to print so that the time of restarting produces change waiting to keep away time set.
Therefore, the objective of the invention is in changing the multirow Synchronization Control, to prevent simultaneously the bad and print speed reduction of print quality.
In order to achieve the above object, the object of the invention printing equipment is provided with the tup group of adorning a plurality of typewriting elements; At least have magnet and pitch of the laps, by the reciprocating mechanism of the tubular linear motor driven that above-mentioned tup group is moved back and forth; Carry the paper advance mechanism of typing paper; During above-mentioned paper advance mechanism carries out the above paper feeding of ormal weight, make above-mentioned tup group keep away any zone to carry out standby, and when paper feeding finishes, reciprocating mechanism is restarted, make above-mentioned tup group return to the common process that moves back and forth, wherein, during above-mentioned paper advance mechanism carries out paper feeding more than the ormal weight, monitor printing the outer time, the outer time of this printing waits that by above-mentioned tup group the time of restarting of time of keeping away and reciprocating mechanism forms; According to its deviation, the time difference of outer time of promptly above-mentioned printing and above-mentioned paper feeding time, the time to be kept away of every kind of predefined tup group of paper feeding amount is carried out the revisal FEEDBACK CONTROL with respect to the paper feeding time of paper advance mechanism.
Specifically, under the short occasion of the paper feeding time of printing the outer above-mentioned paper advance mechanism of time ratio, the printing action that the tup group is moved back and forth in the initial half period after the recovering at least in the process keeps, and treats to begin printing after the next half period.Print quality in the time of preventing to change multirow thus is bad.
And, when keep printing, tup group time to be kept away of predefined every kind of paper feeding amount is prolonged revisal.
Above-mentioned reciprocating motion control method preferably is applicable to have multiple typewriter mode, is provided with the printing equipment of the reciprocating velocity mode of multiple above-mentioned tup group that adapts with these typewriter mode.And the printing equipment that the present invention is suitable for also can be provided with the counter-rotating boosting mechanism near the two ends of the reciprocating amplitude of above-mentioned tup group, realizes the counter-rotating that above-mentioned tup group moves back and forth.
Fig. 1 is the summary side elevation that uses an embodiment of reciprocating mechanism portion of linear motor before the expression,
Fig. 2 is the velocity wave form and the coil drive current oscillogram of tup group,
Fig. 3 is velocity wave form figure and the coil drive oscillogram that comprises the tup group of changing multirow Synchronization Control interval,
Fig. 4 is that expression moves back and forth action diagram,
Fig. 5 is the flow chart that expression tup group of the present invention drives.
Because the structure of reciprocating mechanism portion is same as the prior art, thereby has omitted the explanation to it.Printing equipment of the present invention is similarly can typewrite with a plurality of printing models with former printing equipment, corresponding different typewriter mode, and the reciprocating velocity mode of tup group 10 is also just different.
Fig. 5 is the flow chart that changes the multirow Synchronization Control of the expression embodiment of the invention.
In printing continuously, when not having in by figure the rearmounted computer of expression to accept not change the instruction of multirow, detect the printing end position (S1) that changes before the multirow.Si (i=1,2,3 ...) the expression number of steps.When detecting the printing end position (Si: be), begin to change multirow Synchronization Control (S2), time started instrumentation (S3).Printing the outer time when the last time is changed multirow exceeds the paper feeding time permissible range in addition the time (S4: be), the revisal time to be kept away (S5).Then, since the time instrumentation after wait to keep away effluxion, restart reciprocating mechanism (S6).After recurrence, judge whether tup group 10 arrives printing initiating position (S7).If tup group 10 arrives printing initiating position (S7: be), then concluding time instrumentation (S8) reads in the instrumentation time (S9).The instrumentation time of reading in is to finish to play time till the printing of changing after the multirow begins from changing printing before the multirow, promptly, be the printing time outward when changing multirow.
With predefined paper feeding time with print outer time ratio than (S10).Time begins to print (S, 11) above (S10: be) under the occasion of paper feeding time outside printing.Under this occasion, because the beginning printing changing multirow after is finished paper feeding in during this period of time, thereby the bad accident of print quality that caused by paper feeding can not take place.
Then, judge to print the outer time whether in the paper feeding time allowed band (S12), exceeding (S12: be) under the occasion of allowed band, the revisal time to be kept away (S13) when next time changing multirow.
Wherein, allowed band is decided to be the value that can not influence print quality and print speed.When paper feeding time is taken as Tf, when allowed band is taken as Tp, the value of anti-Tp is set for and can be satisfied following relationship, for example, Tf * 101%≤Tp≤Tf * 110%.
In lower limit, promptly at change reciprocating motion operating state, make under the occasion of the difference of printing outer time and paper feeding time quite little (for example being discontented with 1%), the possibility that does not satisfy paper feeding time when changing multirow owing to the time outside printing next time is higher, thereby when multirow is changed in next time, to wait to keep away the revisal of time lengthening, prevent to print the accident that the outer time do not satisfy paper feeding time.
On the other hand, in higher limit, promptly at change reciprocating motion operating state, make and print the outer time significantly (such as 10%) above under the occasion of paper feeding time, when changing multirow, to wait the revisal that the time of keeping away shortens next time, prevent from paper feeding finish to begin to print to the prolongation of dead time, prevent that print speed from reducing.
Promptly, outside printing the time with respect to paper feeding time than the short occasion of allowed band under, when changing multirow, wait to keep away the revisal of time lengthening next time; Print the outer time with respect to paper feeding time than the long occasion of allowed band under, when changing multirow, wait to keep away the revisal of time shortening next time.
And the time does not satisfy under the occasion of paper feeding time outside printing, and half period (d among Fig. 4) printing (S14) during this period of time behind the multirow is changed in reservation, begins to print from next half period (e of Fig. 4).That is, paper feeding also and does not finish when the printing starting position after changing multirow (c of Fig. 4) upper ram group 10 arrived, if therefore continue such printing then can print quality to take place bad.Thereby keep to print, treat that paper feeding finishes, begin to print (S16) from next half period.In addition, under the occasion of keep printing, meanwhile next time change the multirow counter-rotating time wait to keep away the revisal (S15) of time lengthening.
From above-mentioned explanation as seen, reciprocating mechanism portion at tubular linear motor driven can carry out same reciprocating motion control, the structure of wherein above-mentioned reciprocating mechanism portion is that a counter-rotating boosting mechanism is set, and this mechanism applies power to the counter-rotating that moves back and forth of this tup group near the reciprocating amplitude two ends of tup group 10.
