The specific embodiment
With reference to the accompanying drawings, the embodiment (first embodiment) to the overlapping detecting device of the present invention describes.
Figure 1 shows that printer 1 with overlapping detecting device 2 in the present embodiment.This printer 1 comprises: Printing Department 3 and delivery section 4, and Printing Department 3 is used to print; Delivery section 4 is used for the conveying single paper one by one to Printing Department 3.Delivery section 4 comprises: defeated cardboard 5, and the sheet-fed P that is used for the bay-lift that is not shown by figure is sent successively is placed on it, and side is carried downstream; Before rule 6, the front end that is used for the sheet-fed P that carries with defeated cardboard 5 joins, and adjusts the position of sheet-fed P; Swing (swing) pawl 8 is used to clamp the leading section of the sheet-fed P that has adjusted the position, and gives paper roll 7 paper feedings with sheet-fed P to Printing Department 3.
Under the normal condition, the sheet-fed P that bay-lift is sent is carried on defeated cardboard 5 under the sheet-fed P to the throughput direction upstream side staggers the overlapping state of specified amount continuously.In other words, under the normal feed status, the sheet-fed P that goes ahead of the rest is placed on the defeated cardboard 5 and carries under the overlapping state of specified amount that follow-up sheet-fed P is staggered along throughput direction.Here, specified amount is called as stream spacing (streampitch), is used to represent the distance between the front end of the front end of sheet-fed P and follow-up sheet-fed P, as being set to about 180mm in advance.
Then, sheet-fed P that goes ahead of the rest and preceding rule 6 are joined and are adjusted the position, clamp its leading section by rocking jaw 8, with than delivery speed faster speed downstream layback go out, and to supplying with for paper roll 7 one by one.
The overlapping detecting device 2 that is arranged on printer 1 comprises: sheet-fed detecting sensor 9, and whether the sheet-fed P that is used to detect by assigned position is 1; Amplifier 10 as signal output portion is used for the testing result according to sheet-fed detecting sensor 9, the output overlapped signal; Judging part 11, be used between the reference region of comparison overlapped signal and regulation, the situation of regulation judges to sheet-fed P is normally carried the sheet-fed P to the throughput direction upstream side staggers the overlapping state of specified amount along throughput direction under, is not transferred under normal condition otherwise be judged as.
The structure of sheet-fed detecting sensor 9 is: a pair of up and down end of downstream side that is arranged at defeated cardboard 5 specifically is between defeated cardboard 5 and preceding rule 6, has the sheet-fed P that carries in the way to pass through therebetween.In addition, sheet-fed detecting sensor 9, can adopt sensors known such as electro-optical pickoff, ultrasonic sensor, wherein electro-optical pickoff light shines sheet-fed P, and by its overlap condition through difference detection sheet-fed P of light, ultrasonic sensor arrives sheet-fed P with ultrasonic irradiation, according to having or not air layer (when the sheet-fed P more than 2 is overlapping, producing air layer between the sheet-fed P) to detect the overlap condition of sheet-fed P.
Here, as mentioned above, under normal feed status, the sheet-fed P that goes ahead of the rest is carried under the overlapping state of specified amount that follow-up sheet-fed P is staggered continuously, so not interruptedly continuously by up and down between the sheet-fed detecting sensor 9.That is, under normal overlap condition during conveying single paper P, the state that sheet-fed P is overlapping and 1 's state is passing through with the fixing cycle between the sheet-fed detecting sensor 9 up and down alternately.Therefore, the testing result during normal feed status is: shows 2 intervals that sheet-fed P is overlapping, and show that sheet-fed P is 1 interval, occur alternately with the cycle of fixing.
Here, situation about further sheet-fed P being transferred under normal overlap condition describes.When sheet-fed P was transported on the defeated cardboard 5, the front end of the sheet-fed P of front joined with preceding rule 6 by between the sheet-fed detecting sensor 9, and the mobile of throughput direction of the sheet-fed P of front stops.At this moment, between the sheet-fed detecting sensor 9 be 1 state.Here, the sheet-fed P of front adjusts its position by preceding rule 6.
Afterwards, though the sheet-fed P of front, held in the month its leading section by the grippers of rocking jaw 8 (gripper) 81, during till being held in the month by grippers 81 to the leading section of front sheet-fed P after but the transmission of the throughput direction of the sheet-fed P that follow-up sheet-fed P is in advance stops, also continue to carry, and the leading section of the 2nd sheet-fed P is by between the sheet-fed detecting sensor 9 by defeated cardboard 5.From this moment, become 2 state between the sheet-fed detecting sensor 9.Promptly, after the leading section of the 2nd sheet-fed P arrives up and down between the sheet-fed detecting sensor 9 to the rearward end of the sheet-fed P of front by during till up and down between the sheet-fed detecting sensor 9, sheet-fed P is becoming 2 state between the sheet-fed detecting sensor 9 up and down.
Afterwards, the sheet-fed P of front holds its leading section in the month by grippers 81, to be pulled out than delivery speed faster speed and to be sent to paper roll 7.At this moment, if the rearward end of the sheet-fed P of front by between the sheet-fed detecting sensor 9, then finishes 2 state constantly at this, and becomes 1 state once more between the sheet-fed detecting sensor 9.
Afterwards, the 2nd sheet-fed P becomes the sheet-fed P of above-mentioned front, and according to step as mentioned above, carry successively, paper feeding.
As mentioned above, when sheet-fed P is transferred under normal overlap condition, since the sheet-fed P that goes ahead of the rest with respect to follow-up sheet-fed P stagger specified amount (for example: the stream spacing) overlapping, so between sheet-fed detecting sensor 9, with mutual 1 state and 2 the state of occurring of fixed cycle.That is, by sheet-fed detecting sensor 9, sheet-fed P is detected as the temporal length of 1 state, is respectively fixing length with the temporal length that is detected as 2 state.Therefore, the testing result during normal feed status is: occur showing that sheet-fed P is many overlapping intervals (fabric width) and 1 interval (fabric width) alternately with the fixing cycle.
Here, normally the testing result under the feed status is: show that sheet-fed P is 2 overlapping intervals and show that sheet-fed P is 1 interval with the mutual appearance of fixing cycle, therefore the overlapped signal of amplifier 10 outputs is, first state and second state are with the signal of mutual continuous waveform of fixing cycle.In other words consequently, the overlapped signal under normal feed status is: the interval of first state (fabric width) occurs by the fixing cycle alternately with the interval (fabric width) of second state.In addition, though in the present embodiment, amplifier 10 has constituted CPU jointly with judging part 11 described later and storage part 12, and external situation perhaps is built in situation in the sheet-fed detecting sensor 9 etc. and also is fine.
Judging part 11 is in the interval of first state of the overlapped signal that is transmitted by amplifier 10, with between the reference region of regulation when identical, being judged as sheet-fed P is normally carried the sheet-fed P to the throughput direction upstream side staggers the overlapping state of specified amount along throughput direction under, and not simultaneously, being judged as not to be transferred under normal condition between the reference region of regulation.
Here, between the reference region of regulation, being used to represent the overlapping situation of the sheet-fed P when sheet-fed P is normally carried, is the interval of interval or second state of first state of the overlapped signal when carrying under normal overlap condition.Specifically, between the reference region of regulation can be, the sheet-fed P of throughput direction upstream side is staggered the sheet-fed P that is transferred under the overlapping state of specified amount (amount of stream spacing) during by assigned position (up and down between the sheet-fed detecting sensor 9), detect to sheet-fed P is the length of 1 time by sheet-fed detecting sensor 9, perhaps be detected as the length of 2 overlapping times.Perhaps, the amount that also can be sheet-fed P stagger with respect to the sheet-fed P of throughput direction upstream side promptly flows spacing.Between the reference region of described regulation, by such as: operator input or with the 1st, 2 of fronts by the time the interval mode such as store as benchmark, be stored in the storage part 12 that constitutes CPU.
In addition, under normal condition, be not transferred and be not meant: the sheet-fed P that goes ahead of the rest, with the state of specified amount that follow-up sheet-fed P is not staggered overlapping situation about being transferred, such as, stagger be greater than or less than specified amount overlapping the state that is transferred.
In addition, overlapping detecting device 2 comprises: as defeated cardboard shutdown feature fly reach stop solenoid (solenoid) SOL, be used for being judged as when not being normal feed status by judging part 11, receive from the danger signal of judging part 11 and stop defeated cardboard 5; As the notice lamp of notifying device, be used for being judged as when not being normal feed status by judging part 11, receive notification signal and bright lamp or flicker from judging part 11.In addition, the notice lamp can adopt as LED etc., except bright lamp, flicker, also can notify by turn colors on its structure.
Below, with reference to diagram of circuit shown in Figure 2, the control method of the overlapping detecting device 2 in the present embodiment is described.
At first, start printer 1 printing sheet-fed P.Like this, rocking jaw 8 each several parts such as grade and the revolution run-in synchronism of giving paper roll 7, and sheet-fed P sends and is carried by defeated cardboard 5 from bay-lift.When sheet-fed P was transferred on defeated cardboard 5, whether sheet-fed detecting sensor 9 detects by the overlap condition of the sheet-fed P between the sheet-fed detecting sensor 9 up and down was 1, and its testing result is sent to amplifier 10 (step S1).
Judging part 11 is received overlapped signal, read between the reference region of storing in the storage part 12 and (in the present embodiment be: under the normal overlap condition, be detected as many overlapping time spans by the sheet-fed P between the sheet-fed detecting sensor 9 up and down, promptly, the burst length of first state of overlapped signal under the normal feed status), and relatively between the interval and reference region of first state of overlapped signal (step S3).In addition, what adopt when between reference region is, under the normal overlap condition when the sheet-fed P between the sheet-fed detecting sensor 9 is detected as 1 time span up and down, promptly, under the normal feed status during burst length of second state of overlapped signal, judging part 11 is relatively between the interval and reference region of second state of overlapped signals.
Here, when both sides interval identical, judging part 11 is judged as under normal condition and carries, and continues between the interval and reference region of first state of overlapped signal relatively.On the other hand, when both sides' interval not simultaneously, judging part 11 is judged as and is transferred (step S4) under normal condition.
Be judged as when under normal condition, not being transferred (when the interval of first state of overlapped signal is longer than or is shorter than between reference region), judging part 11 output danger signal and notification signals (step S5, step S6), receive danger signal fly reach stop solenoid SOL and stop the conveying (step S7) that defeated cardboard 5 stops sheet-fed P, the notice lamp of notified signal is by the bright lamp or the notification operator (step S8) of glimmering.
Like this, by relatively between the interval and reference region of first state of overlapped signals, judging that whether the sheet-fed P that is transferred is transferred, and can check out the paper feeding fault thus under normal overlap condition by judging part 11.
Then, other embodiments (second embodiment) to the overlapping detecting device 2 of the present invention describe.In the present embodiment,, use prosign, and omit explanation for the structure identical with first embodiment.Overlapping detecting device 2 in the present embodiment comprises: sheet-fed detecting sensor 9, amplifier 10, judging part 11, the storage part 12 of Memory Reference time (timing), fly to reach stop solenoid SOL and the notice lamp, further comprise coder 13, be used for output revolution signal, this revolution signal is as the printing benchmark of printer 1.
Judging part 11, at printing benchmark at printer 1, the time (timing) that first state of overlapped signal and second state switch, when identical with the fiducial time of regulation, be judged as sheet-fed P at sheet-fed P to the throughput direction upstream side, under throughput direction staggers the overlapping state of specified amount, normally carried, with fiducial time of regulation not simultaneously, be judged as and under normal condition, be not transferred.
Here, the time (timing) that first state and second state switch is meant: with the revolution to paper roll 7 is benchmark, at first state of this benchmark overlapped signal and the moment of second state switching.Specifically be meant, when since the H state of revolution signal of own coding device 13 when being benchmark, overlapped signal from first state to the moment that second state switches, perhaps, from second state to moment that first state switches.
On the other hand, as mentioned above, when sheet-fed P is transferred under normal overlap condition, the sheet-fed P that goes ahead of the rest with respect to follow-up sheet-fed P stagger specified amount (such as: the stream spacing) overlapping, so between the sheet-fed detecting sensor 9,1 state and 2 s' state occurred alternately with the fixed cycle.And generally speaking, the action of rocking jaw 8 is synchronous with the revolution of giving paper roll 7, so the paper feeding one by one of sheet-fed P carries out synchronously with the revolution of giving paper roll 7.Therefore, when sheet-fed P is transferred under normal overlap condition, by the sheet-fed P between the sheet-fed detecting sensor 9, switch to the time of 2 state from 1 state, perhaps, switch to time of 1 state, synchronously switch with the revolution of giving paper roll 7 from 2 states.
Here, be meant the fiducial time of regulation: under the situation with this normal overlap condition conveying, be benchmark, at first state of this benchmark overlapped signal and the moment of second state switching with the revolution of giving paper roll 7.Specifically, be meant the fiducial time of regulation: under the situation of carrying with normal overlap condition, since the H state of revolution signal of own coding device 13 when being benchmark, overlapped signal from first state to moment that second state switches, or, from the moment of second state to the switching of first state.Accordingly, the fiducial time of described regulation, by such as: operator input or with the 1st, 2 of fronts by the time time mode such as store as benchmark, be stored in the storage part 12.
Below, with reference to diagram of circuit shown in Figure 4, the control method of the overlapping detecting device 2 in the present embodiment is described.
At first, running press printing sheet-fed P then gives paper roll 7 revolutions, and according to its turning interval, the various piece run-in synchronism of rocking jaw 8, defeated cardboard 5 etc.For example, sheet-fed P paper feeding was 1 during the revolution run-in synchronism of each several part and paper roll 7 can make paper feeding cylinder 7 turn round 1 time.So, sheet-fed P is transferred on defeated cardboard 5 at each position and under the synchronous operated state of revolution of paper roll 7.Then, whether sheet-fed detecting sensor 9 detects by the overlap condition of the sheet-fed P between the sheet-fed detecting sensor 9 up and down is 1, and its testing result is sent to amplifier 10 (step S11).
After amplifier 10 is received testing result, according to this testing result, output becomes first state (H state), becomes the overlapped signal of second state (L state) in the underlapped interval of sheet-fed P in the overlapping interval of sheet-fed P, and is sent to judging part 11 (step S12).
On the other hand, coder 13 will be sent to judging part 11 (step S12) based on the revolution signal of the revolution benchmark of giving paper roll 7.
Judging part 11 is received the overlapped signal of amplifier 10 transmission and the revolution signal that coder 13 transmits, and instrumentation is at first state of the overlapped signal of revolution signal and the time (step S13) of second state switching.Then, read the fiducial time (in the present embodiment being :) of storage part 12 storage, relatively the time and the fiducial time (step S14) of instrumentation at first state of the overlapped signal of normal feed status turning down signal and the time that second state switches.In addition, what adopted fiducial time is, during time of switching at second state and first state of the overlapped signal of normal feed status turning down signal, the time that judging part 11 instrumentations switch at second state of overlapped signal and first state of revolution signal, and itself and fiducial time compared.
Here, when both sides' time equated, judging part 11 was judged as under normal condition and is transferred, and continued the relatively time and the fiducial time of instrumentation.On the other hand, when both sides' asynchronism(-nization), judging part 11 is judged as and is transferred (step S15) under normal condition.
Be judged as when under normal condition, not being transferred when being later than fiducial time (time of instrumentation early than or), judging part 11 output danger signal and notification signals (step S16, step S17), receive danger signal fly reach stop solenoid SOL and stop the conveying (step S18) that defeated cardboard 5 stops sheet-fed P; The notice lamp of notified signal is by bright lamp or flicker notification operator (step S19).
So, by relatively at first state of the overlapped signal of the revolution benchmark of giving paper roll 7 and time and the fiducial time that second state switches, can judge that whether the sheet-fed P that is transferred is transferred, and can check out the paper feeding fault thus under normal overlap condition.
In addition, in first embodiment and second embodiment, the situation that structurally can export the overlapped signal that becomes first state (H state) and two states of second state (L state) as the amplifier 10 of signal output portion is illustrated, but be not limited thereto, structurally also can export the overlapped signal that becomes three states.Specifically, amplifier 10 structurally can be exported following overlapped signal, that is: become many of normal conditions (M state), sheet-fed P when up and down the sheet-fed P between the sheet-fed detecting sensor 9 is 0 and become first state (H state), sheet-fed P become second state (L state) when being 1 overlapped signal when overlapping.In view of the above, can detect by the sheet-fed P between the sheet-fed detecting sensor 9 up and down is 0 state, and can promptly find out the content of paper feeding fault.
The above is preferred embodiment of the present invention only, is not in order to limit the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
