Description

The record paper loading method of printer
Technical field
The present invention relates to be printed at certain intervals along its length typewriting on the strip chart of black designation and carry out the stowage of the record-paper on the printer etc. of bill distribution as the bill of certain-length etc.
Background technology
In the middle of bill printer etc., as record-paper, when using the cylinder paper that the strip chart that is printed on black designation is rolled into tubular and constitutes, can control the transmission of record-paper and print action according to black designation, and with certain-length issued notes one by one.
This printer, the path that in general arrives the off-position of hand papercutter behind approach feeding-in roll and the print position is transmitted by cylinder paper and is extracted banded record-paper out, in the anterior position of feeding-in roll, detects the black designation of printing on record-paper.In case measure black designation, constantly just send record-paper from that by predefined sendout, become the record-paper front end is positioned at state on the hand papercutter off-position.From this state, in case record-paper is just in time sent a bill length (interval of black designation), just the next off-position with record-paper is positioned on the off-position of hand papercutter.Cut off record-paper with this state, just can obtain a bill.
When loading cylinder paper, need from the cylinder paper that is contained in printer cylinder paper filling department, extract record-paper out along the transfer path guiding, and form the state that its front end is positioned at the hand papercutter off-position.After still unspent cylinder paper in will using takes out from cylinder paper filling department, the loading that also must be correlated with when loading once more.
Here, when the roll web of carrier tape black designation, with hand the holding paper portion that record-paper inserts feeding-in roll is driven this feeding-in roll afterwards, begin to send the action of record-paper, after detecting black designation, if just in time send the record-paper of predefined sendout, just can form the record-paper front edge is positioned at loading condition on the hand papercutter off-position.
Yet, if when cutting off the black designation upstream side measure, and the interval from the subsidiary off-position of record-paper to black designation than from the record-paper off-position of printer to measuring under the also long situation of path till the black designation position, the record-paper front edge will surpass the off-position of hand papercutter before measuring black designation.In this case, for the record-paper front edge is positioned on the hand papercutter off-position, before measuring the next black designation of record-paper, just need further send record-paper, and the next off-position of record-paper is positioned on the hand papercutter off-position, and last record-paper partly torn it down throws away.This method is when loading cylinder paper or when loading once more, the often waste of occurrence record paper.
For fear of the waste record-paper, make the feeding-in roll counter-rotating, record-paper is sent back to, as long as be positioned on the hand papercutter off-position front edge just passable., in case reverse transfer sheet, record-paper is a relaxed state on from cylinder paper filling department to the transfer path of feeding-in roll, just may be absorbed in the paperboard state on this transfer path, so inadvisable.
Summary of the invention
In view of this point, problem of the present invention is to propose the printer record paper stowage that a kind of waste that can not cause record-paper and paperboard ground load with the strip chart of black designation.
In order to solve above-mentioned problem, the record paper loading method of printer of the present invention, it is characterized in that: measure passing through of the strip chart front end that inserts this feeding-in roll holding paper portion in the position, front of feeding-in roll, in case measure the conveying action of passing through just to begin to be undertaken record-paper of record-paper front end by above-mentioned feeding-in roll, on the position, front of above-mentioned feeding-in roll, measure passing through of the black designation of printing on the record-paper, when the record-paper sendout (L) of passing through and being undertaken of not measuring above-mentioned black designation by above-mentioned feeding-in roll in case reach first sendout (L1) of the distance of corresponding holding paper portion from this feeding-in roll till the record-paper off-position, the record-paper that just stops to be undertaken by this feeding-in roll is carried action, if when reaching above-mentioned first sendout (L1) before in above-mentioned sendout (L), in case measure passing through of above-mentioned black designation, just measure from this and constantly above-mentioned record-paper is just in time sent predefined standard sendout (L0), the record-paper that finishes then to be undertaken by above-mentioned feeding-in roll is carried action.
When the interval of the subsidiary off-position of record-paper and black designation cuts off the record-paper position to measuring the black designation position when long than the hand papercutter from printer, owing to do not measure passing through of black designation when record-paper loads, so control the sendout of record-paper according to measuring of black designation, just front edge can not be positioned on the off-position at record-paper.Yet method of the present invention is to preestablish first sendout (L1) of corresponding holding paper portion from feeding-in roll to the distance of record-paper off-position, when not measuring black designation, just just in time sends the action of first sendout (L1) record-paper.Thereby, even do not measuring under the situation of black designation, also can form the record-paper front edge is positioned at state on the record-paper off-position.Therefore, the method according to this invention when loading record-paper, can not wasted record-paper, in addition owing to not needing reverse transfer sheet, so can not be absorbed in the state of paperboard.
Here, method of the present invention is characterized in that: regulation time delay was set between the zero hour of measuring the moment that above-mentioned record-paper passes through and the action of being sent record-paper by above-mentioned feeding-in roll.Because the holding paper portion from the position of measuring record-paper to feeding-in roll separates, so when with hand insertion record-paper, record-paper can produce the delay about 0.1~1 second from measuring the holding paper portion of reality insertion feeding-in roll.By under the prerequisite of considering this delay, driving feeding-in roll, can prevent the idling conditions of feeding-in roll, thereby can correctly carry out sending of record-paper.
In addition, method of the present invention in the conveying action of above-mentioned record-paper just in time being sent above-mentioned first sendout (L1), is set at the rotation amount of described feeding-in roll more than the rotation amount corresponding with this first sendout.After record-paper was inserted the holding paper portion of feeding-in roll, record-paper can be involved in by feeding-in roll immediately, can produce a bit to postpone before being involved in.Consider that this postpones, and by strengthening the rotation amount of feeding-in roll in advance, just can correctly send the record-paper of first sendout (L1).
Then, method of the present invention, it is characterized in that: at the same position of record-paper direction of transfer, utilize first and second optical sensor of the reflection-type of configuration at certain intervals, carry out to the detection of passing through of the front end of described record-paper with to the detection of passing through of described black designation.
Promptly, above-mentioned first optical sensor measured the pass through position of area configurations in above-mentioned black designation, above-mentioned second optical sensor measured area configurations in the position of passing through of departing from black designation, when the light income of two optical sensors is that setting is when following, just being judged as does not have record-paper, in the light income of two optical sensors, when surpassing setting, at least one side just has been judged as record-paper, when the light income of above-mentioned first optical sensor is below the setting, and when the light income of above-mentioned second optical sensor surpasses setting, just be judged as and measured above-mentioned black designation.
Like this according to the output of two sensors, can measure having or not and simply judging whether to measure black designation of record-paper simply.
Then, printer of the present invention is characterized in that: have: the filling department that is rolled into the strip chart of tubular; Be used to transmit feeding-in roll from the described record-paper of described filling department extraction; The printhead that prints at described record-paper; Cut off the hand papercutter of described record-paper at width; Be used to detect the test section that is printed on the black designation on this record-paper along the length direction of described record-paper at certain intervals, direction of transfer along described record-paper, described test section, described feeding-in roll, the off-position of described printhead and described hand papercutter, arrange in proper order by this, if be installed in the holding paper portion that the interior record-paper front end of described filling department is inserted into described feeding-in roll, then utilize the record paper loading method of any described printer in the claim 1 to 5, carry out described record-paper front edge is positioned the loading action of the described off-position of described hand papercutter.
According to printer record paper stowage of the present invention, when loading record-paper,, also can form the record-paper front edge is positioned at loading condition on the hand papercutter off-position even can not survey black designation.Therefore, just need till the next hand papercutter off-position that arrives the record-paper off-position, not send record-paper, assign to the record-paper front edge has been positioned on the off-position by cutting off its fore head.In addition, do not need the reverse record-paper of sending yet, and the record-paper front edge has been positioned on the off-position.Thereby, the method according to this invention, waste and paperboard that can occurrence record paper just can be loaded.

The specific embodiment
Below, with reference to accompanying drawing, the embodiment that is applicable to cylinder paper printer of the present invention is described.
Fig. 1 is the stereoscopic figure of cylinder paper printer, and Fig. 2 is the stereogram of the cylinder paper printer under the state of uncap.In addition, Fig. 3 is the part amplification profile of the III-III line section part of presentation graphs 2, and Fig. 4 is the summary pie graph of expression control system.
As shown in Figure 1, 2, the cylinder paper printer 1 that this is routine is equipped with the rectangle printer cabinet 2 of lengthwise as a whole, and this printer cabinet 2 is equipped with the casing 3 and the switch cover 4 (chassis lid) of rectangular frame shapes.Switch cover 4, its back portion is the center with the rotation that extends to the printer width, is installed on the casing 3 with rotatable state, can be rotated to fully open position 4B shown in Figure 2 from closed position 4A shown in Figure 1.
In the inside of printer cabinet 2, the Machinery Ministry 5 of printer is installed in its first half, in latter half, form cylinder paper filling department 6.Open switch cover 4, just expose cylinder paper filling department 6, can load cylinder paper 10 from upside.
The cylinder paper 10 that this is routine, as shown in Figure 4, strip chart 10a constitutes to be rolled into tubular, on the printing surface 10b of record-paper 10a, prints rectangular black designation 10c along its length at certain intervals in a lateral edge portions.By black designation 10c, can control the transmission action of record-paper 10a and print action.In addition, as described later,, can control cylinder paper 10 is seated in the record-paper loading action of being carried out when cylinder paper filling department 6 is adorned by black designation 10c.
Printer Machinery Ministry 5 is forming recording paper transportation path footpath 7 shown in some chain lines among Fig. 3.Via recording paper transportation path footpath 7, the strip chart 10a that extracts out from the cylinder paper 10 of cylinder paper filling department 6 fillings is directed into the record-paper outlet 9 that is formed by switch cover 4 via print position 8, again from discharging upward here.
Print position 8 determines that by the surface portion of pressboard 11 women's head-ornaments from printer front side printhead 12 stand facing each other with certain interval here.This routine printhead 12 is impact heads.Printhead 12 is installed on the printing head support part 13, and printing head support part 13 can come and go mobile on the width of printer along the leading axle 14 that sets up.Front side at printing head support part 13 forms ribbon cartridge installation portion 15.Open switch cover 4, expose this ribbon cartridge installation portion 15, just can with removable state inked ribbon box 16 be installed from upside.
Than the print position 8 in recording paper transportation path footpath 7 more by sender's upstream position configuration feeding-in roll 17 and be pressed in letterweight roller 18 on this feeding-in roll 17.At the position of more leaning on the direction of transfer upstream side than the holding paper portion 19 of these rollers 17,18, first and second optical sensor 21,22 of configuration reflection-type.By these optical sensors 21,22, that can carry out that record-paper has or not measures and the measuring of black designation.
The optical sensor 21 of one side will be printed on the lateral edge portions of black designation 10c as measuring the zone on the record-paper 10a printing surface 10b.Another optical sensor 22, with the opposite side marginal portion of record-paper 10a printing surface 10b as measuring the zone.In addition, these optical sensors 21,22 measure the zone, on the record-paper direction of transfer, be in same position.Under the state that does not have record-paper 10a, because the light income of two optical sensors 21,22 all is below the threshold value, can measure does not thus have record-paper 10a.Under the state that record-paper 10a is arranged, there is the light income of two optical sensors 21,22 all to surpass threshold value and have only the light income of optical sensor 22 to surpass two kinds of situations of threshold value.In the latter case, black designation 10c is the state of measuring the zone that is positioned at optical sensor 21.Therefore, surpass under the state of threshold value at the light income of optical sensor 22, when the light income of optical sensor 21 is threshold value when following, just can be judged to be is the moment of black designation process.
Then, manual hand papercutter 23 is installed near the position record-paper outlet 9 in recording paper transportation path footpath 7.The fore-end of the record-paper that record-paper outlet 9 can be discharged downcuts to the blade (off-position) 24 that the printer width extends along manual hand papercutter 23.
As shown in Figure 4, the control system of the cylinder paper printer 1 that this is routine is general device, and being equipped with the computer is the driving control device 30 that the center constitutes, and by this driving control device 30, drives control printhead 12 between driver 31.In addition, drive paper feeding motor 33, carry out the paper of feeding-in roll 17 and carry action between motor driver 32.In case supply with print command and print data from said apparatus 34, driving control device 30 just with transfer sheet 10a driven in synchronism printhead 12, carries out the printing of a bill in the zone of defined by the black designation 10c on the printing surface 10b.After print finishing, the position of a bill rear end promptly forms off-position is positioned at state on manual hand papercutter 23 off-positions 24.The operator arrests the fore-end of record-paper 10a, downcuts the fore-end of this record-paper 10a along the off-position 24 of manual hand papercutter 23, just can issue a bill to client.
Here when cylinder paper 10 is loaded into cylinder paper filling department 6, record-paper 10a is pulled out along recording paper transportation path footpath 7, make its front edge 10d be positioned at the loading action of the off-position 24 of manual hand papercutter 23.If using the cylinder paper of half, filling also carries out identical action.This routine printer 1 is according to the result that measures of a pair of optical sensor 21,22, as the following loading that carries out record-paper.
Fig. 5 is that the record-paper of expression cylinder paper printer 1 loads the general flowchart of action.Load action with reference to this figure declare record paper.Open switch cover 4 with the cylinder paper 10 cylinder paper filling department 6 of packing into.Then, the operator pulls out record-paper 10a from cylinder paper 10, and its fore-end is inserted the holding paper portion 19 of feeding-in roll 17.
In case the operator inserts feeding-in roll 17 with the fore-end of record-paper 10a, just measures the record-paper 10a (step ST1) of insertion by a pair of optical sensor 21,22 that is configured in position, feeding-in roll 17 front.After measuring record-paper 10a, in fact the holding paper portion 19 of record-paper front edge 10d arrival feeding-in roll 17 needs some time.Therefore, this example from measure insert record-paper 10a the moment after the time delay of regulation, beginning is carried action (step ST2,3) by the paper that feeding-in roll 17 carries out.Time delay, for example just passable about 0.1~1 second.
Beginning is undertaken by feeding-in roll 17 according to the output of a pair of optical sensor 21,22, measuring the moment (step ST4) of black designation 10c by this position after the record-paper 10a transmission.
Here, the distance from the holding paper portion 19 of feeding-in roll 17 to the off-position 24 of manual hand papercutter 23 is known, and the first sendout L1 that should distance is set in advance in the driving control device 30.When the sendout L of record-paper 10a reaches when not measuring black designation 10c before the first sendout L1, just reached for first moment of sending ML1 at sendout L, stop feeding-in roll 17, finish paper and carry and move (step ST4,5,6).Its result just forms the state on the off-position 24 that front edge 10d with record-paper 10a is positioned at manual hand papercutter 23.
This sendout L as record-paper 10a is reached when measuring black designation 10c before the first sendout L1, just carry out the common control of sending according to black designation.That is,, just in time send after the record-paper 10a of predefined standard sendout L0, finish the conveying action (step ST4,7,6) of this record-paper 10a from measuring the moment of black designation 10c.Its result just forms the state on the off-position 24 that front edge 10d with record-paper 10a is positioned at manual hand papercutter 23.
, record-paper 10a is just in time sent the rotation amount of the feeding-in roll 17 of the first sendout L1 here, bigger slightly than the sendout that is equivalent to from holding paper portion 10 to off-position 24 distance.That is,, postpone though in fact before the front edge 10d of record-paper 10a is involved in holding paper portion 19 and begins to transmit, seldom also still can produce a bit even insert at the front edge 10d of record-paper 10a under the state of holding paper portion 19 of feeding-in roll 17.Consider that this postpones (idling conditions of feeding-in roll), sets the rotation amount of feeding-in roll 17.Its result can be positioned at record-paper front edge 10d on the off-position 24 accurately.For example, in advance with the rotation amount of feeding-in roll 17, be set at that to many rotation amount of 0.5mm~3mm left and right sides sendout than the first sendout L1 just passable.
Cylinder paper printer 1 as described above, that this is routine when being contained in cylinder paper 10, being not limited to and whether measuring black designation 10c, record-paper front edge 10d can also be positioned on the off-position 24 of manual hand papercutter 23.Therefore, do not need to waste a bill, do not need reverse transfer sheet in addition yet.
Moreover this example was measured under the situation of black designation before the sendout L of record-paper 10a reaches the first sendout L1 when loading record-paper 10a, just carried out common paper according to black designation and sent.Replace in this, be not limited to and whether measure black designation, also can when loading record-paper, often just in time send the record-paper 10a of the first sendout L1.
In addition, this printer particularly in order to improve the correctness of not measuring bill under the black designation situation, also carries out following control.
Sendout L reach first send SL1 after, print to record-paper 10a, the in-process of paper feeding repeatedly measures black designation.Its black designation measure the position for desirable position, carry out if in permissible range, just be judged as " normally " in the same old way, if departed from the position of permissible range, just be judged as " unusually " and cease operation, with the black designation of measuring is that standard is carried out paper and sent control, the discarded thing of printing so far and printing again.
According to above-mentioned formation, for example, can prevent under the situation of the record-paper that insert to cut off from front, or spend till transmit under the situation above the time more than the permissible range, depart from the distribution of the bad paper of print position when the front edge 10d of record-paper 10a is involved in holding paper portion 19.
