Description

[Detailed description of the invention] The non-invention relates to I1 body inhalation.

Special &: Jl 1 It is applied to the medium suction part which sucks the medium to supply the medium, such as a sheet, of the body g collecting device.

When there was a feed error of the medium, I took the medium for 2 seconds and tried to sleep by inhaling it.

For example, the characters written on the @-based media are read by an optical character-retrieval unit, and forms are processed based on this reading. in this case.

The medium extracting device for capturing the appearance of characters such as kanji characters is equipped with a medium suction section as shown in FIG. In this media suction section,
As shown in the diagram, the decimal @vote, α, and so on in the hopper part 1,
These forms are accumulated horizontally, gs, ilm-
... is the feeder 1 which is energized by the spring 2 from the back.
It is pressed against the pickup roller 4 at 413.

When the pickup roller 4 rotates in the direction of the arrow shown in the figure, the form a1 is supplied to the suction separator 5 by the pickup roller 4. The @form gm that is touching this form set is transferred to the first system @l. It is dragged a little and moved towards the suction separator 5. Since the suction separator 5 is empty enough to pass one document, only the document 111 passes through the suction separator, and the machine operation is stopped here. As a result - vote #-1 is sent towards roller 6.6' (0 feed) roller 6.6'
tt Since it rotates in the direction of the arrow shown in the figure, the @ entertainment 61 is sucked in, and is sent downward from this feed row 26.6' and detected by the medium detection sensor (hereinafter referred to as sensor) 7. The form 61 is further supplied to a character reading section or a marking section (not shown), where characters or marks are removed. on the other hand.

When Queen Senna 7 detects this lI#ii vote withdrawal, the pickup roller 4 is stopped by a detection signal generated.

It is necessary to maintain a constant distance between the form @t and the subsequent form S-, so that the alIiL entry of @114m5 and subsequent inquiries can be made smoothly. The bales, whose constant spacing was controlled by the earthenware #il (not shown), are now separated from each other by the rotation of the pick-up roller 4 and the paper-feeding roller 6. "After being inhaled and detected by sensor 7, WL is filled.

This is also the place where documents such as inquiries are processed.
The pickup row 94 is stopped by the detection signal.

Similarly, @vote 111. #4... is maintained at a constant interval and is sequentially supplied to the feed rollers 6 and 6s.

Each vote is processed.

However, Nao Tsuki et al.'s jiilW! Due to the environment of A, the difference in the paper quality of the forms, the setting conditions of the forms, etc., even if the pickup roller 4 rotates, the forms are not sucked into the feed rollers 6, 6'' and are not detected by the sensor 7, which may cause a feed error. The cause of this feed error is that if the friction between the pickup roller 4 and the form is smaller than the 4 friction between the form and the following @ken, a foreign object may enter between the pickup roller and the form. If the jlls force is reduced, the J$lsgkwL between the pickup roller 4 and the form may become smaller, such as when the force is reduced due to the force of the spring.1
'Ta. @ Due to the twisting of the vote or the loop thread of ff1d being shifted, the air of the suction sebaret/S may be roared. In this way, l! When an IJI feed error occurs, the sensor 7 does not generate a detection signal, so the pickup roller does not stop. If this detection g1t does not occur for a certain period of time, #@ will be generated in the warehouse.

When the operator learned that there had been a feed error, he took measures to disseminate the information, such as manually feeding the form himself. However, such manual operation has an ineffective rate, and when such a feed error occurs, it is necessary to automatically correct it in the warehouse.

Therefore, misfire 11IF! , as mentioned above, conventional medium a
In the ys device, there is a media feed (wealth,
In order to improve the failure rate due to manual correction to ensure smooth supply of forms, the system shocked the aS body when the s-body detection signal was not generated.
This provides a medium suction system that automatically supplies documents smoothly. For that purpose, the medium inhalation method of the present invention is! In a medium reading device in which an R-layered medium is sent out by an inhalation command by a 7-year-old 7ytsuj-2 and is engraved into the device, the medium is not inhaled by the pickup roller 42. Detection means for detecting tweedons, such feed misses are avoided.
A retry control means that has a retry control hand that performs a retry due to a dispute that has been issued is the above-mentioned (
The WIL accumulated above before the operation of Tsukuarakara starts.
It is characterized by a fist configured to burn and impact the medium it picks up.

Next, before explaining one embodiment of the present invention in detail, 112
The uninvented raw salt will be explained in detail based on the diagram.

Figure 112(c) is a partial side view of a medium reading device using an embodiment of the present invention; the same figure is a front view thereof; The same reference numerals as in Fig. 1 indicate the same constituent parts. Here, as shown in Figure 2 (see Figure 2)

For example, if there is a feed error in the form 61, first swing the swing cams 8-0, 8-1, 8-2, and 8-3 to apply an m-impact to the rock #&sharp, and then the pickup roller 4,4'? By making one rotation, an attempt is made to make the feed rollers 6, 6' normally suck in the document set. In this way, if a trial is performed in which the bitter up roller 4.4' is rotated after applying a 1 m long impact to the @ slip 61, the above-mentioned interpolation point can be improved. That is, #4sα1
is instantaneously separated from Form 3 following 4, the resistance of Teso is reduced, the Agj between Pickup Lotz and @114 group is eliminated, and the elasticity of the spring of the feeder is corrected. , -4a*I4big-a-prots4.
It rubs against 4's and makes it easier to drive normally.

As a result, the twist of @vote a1 is corrected, and the position of the subsequent mock vote that is blocking the passage of @vote-weight is also corrected.
@@ gt makes it easier to pass through the suction separator 5 ◎ In this way, correction of the feed error in Form-1 is attempted, but
If this trial is repeated, the correction of feed errors in the book 4411 will become more reliable.

An embodiment of the present invention will now be described in detail based on FIGS. 1112 and 113 with reference to the principles of the present invention described above.

5aWJ is a circuit configuration diagram of this example. 9 is a retry control section, 10 is an OR circuit, and 41 is a bit-up roller control section (hereinafter referred to as roller control section).

12 is a feed error detection unit t13tt and both damage and force control units;
Ml is a pickup rotor (hereinafter referred to as a roller motor), and MI is a distributing cam plate.

*a* The cam 8 has a shape in which a part of the circular arc portion of a disc is cut out, as shown in #I2 diagram C→. The swing cam 8 is made of a material 2, such as stainless steel, that does not easily damage the form. The oscillating force 58-0 has plowing cams 8 arranged as shown in Fig. 2-).

The notch 86 of the rocker arm 8 rotates about 45 degrees, and its tip slightly protrudes toward the form, making a reciprocating angular movement so as to apply the above-mentioned light impact to the form. 4 intestinal power 58-1, 8-2
, 8-3 are also used to apply an impact 41- to the form in the same way as the swing cam 8-0.

This is also configured in the same way as the 411111 power^.

The retry control unit 9 controls the swing cam so that when there is a feed error in the @ vote, re-inhalation of the bird 411m can be attempted.
1131 and the roller control section 11. This retry control unit 9 uses @number counter 9
-0 is built in, and even if the re-inhalation is attempted twice, if there is still a feed error, a feed error signal is generated. In addition, during the trial of the upvote, the first swing cam control section 13
By operating the 1I4IIlb cam motor positive, the swing cam 8-O, Lu-h-168-2゜8-3 is moved to the reverse angle mΔ.
After that, the OR circuit 1O operates the roller control #@11 to operate the pickup roller 5 by the roller motor M1. Queen Rez IIl! 1
When either one of the control spears in Part II is suitable,
1" is output.

The four-ra control l111 operates the roller motor Ml when rlJ is output from the OR circuit lO.

The feed error detection unit 12 detects a feed error in the weft yarn, and internally controls the timer 12-0, and activates the timer 12-0 when rlJ is transmitted from the or@ro lO. He said that the detection signal from Senna-7 that detected the @ system was delayed within the time set by timer 12-0.
Alternatively, if the detection signal is transmitted from the sensor 7 within the set time of the timer 12-0, the a=90% control section 11 is controlled to stop the roller motor M. At this time, when the detection signal is transmitted, if the detection signal is not suitable, the tie size -12-0 is set. Further, the feed error detection section 12.

Tie ff-12-00 If the above detection signal is transmitted within the set time, a lock operation end signal will be generated, and if the detection signal is not transmitted within this set time, it will be a non-detection signal indicating an old or unwary output. 2 part is sent to 9.

Oscillating force ^ control 1 [13 is for controlling 11 m force 50 angular movement, and the oscillating cams 8-0, 8-1, 8-2, 8- are controlled by the retry system aSS. 3 to 1
The oscillating cam motor M1 is operated so as to shift the reciprocating angle.

Next, the operation of the broom gwI and the present embodiment shown in FIG. 3 will be explained.

(Ge) It is written that the form has been successfully aspirated.

First 11211! Turn on the power switch (not shown) of the medium removal device shown in I (a), move the feed roller 6, 6' in the direction of the arrow shown in the figure, and set the sensor 7 to the full state. Then, the suction condensation is transmitted from a part not shown in the figure to the OR circuit IO, and from this OR circuit IO, "1" is transmitted.

t travels towards the suction separator 5. When the feed is running normally and IIIJlax passes through the gap in the suction separator 5 and is sucked into the feed rollers 6゜6', and is further detected by the sensor 7, this detection signal is sent to the feed miss detection section 12. and is transmitted to tie ff-12-0. As a result, the feed error detection unit 12&'f,
An instruction is given to both roller parts 11 to stop the roller motor M1.

The timer 12-0 is reset and an S operation end signal is generated. In this case, book! This means that Sαl was inhaled normally. The main control section receives this operation charge r and outputs the next inhalation command. In this way @Entertainment 81 @IBm-・

Even if the suction command is applied and the roller motor storage rotates normally as described above, what happens? 1. For example, the book Jlla- is the feed roller 6. If you don't want to inhale normally, then tie it! -12-
Feed access detection unit 1 from 7th t-7 within the set time of 0
Since the detection signal is not applied to 2, the feed miss detection unit 12 transmits the tl non-detection signal to the retry mwi unit 9, and controls the roller tllJ 11 unit 11 to stop the roller motor M1. As a result, the number counter 9-0 counts 1, and the retry illJm unit 9 gives an instruction to the swing roller control gla to operate the swing motor, thereby *Il cam 8-0°8-1, 8-2, 8-3 round trip round trip! l
Make IJ and give horizontal asC@vs@ attack. After this, the retry system #@9 controls the low 2 system city section 11 via the OR circuit 10 to operate the ■-Lameau M1, thereby attempting to normalize the intake for the book Jllam.

As a result, @votohiki is directed to run to the intake Severe JSIIil. On the other hand, feed miss detection [12
The timer 12-0 is activated by the output rlJ of the OR time @10. Then, when the above-mentioned form pull is sucked into positive g in the above trial, a detection signal is transmitted from the sensor 7 to the feed error detection section 12, so this feed error detection section 12 controls the roller control section 11. loaf motor M
Stop the control and reset timer 12-0. Then, for the retry control part, 1gI number of commenters 9

I believe that normal inhalation of the form was not achieved even by re-inhalation.

If the form 13 is not suctioned normally even after a successful attempt in -) above, the feed error detection s12
The non-detection signal is sent to the 'J try control section 9 again, and the roller motor M1 is stopped in the same manner as above.

In the retry control section 9, the 2 times counter 9-0 counts 2 stitches. In this case, the retry control unit 9H is used in the same manner as in the above l&first trial.

First, the swing cams 8-0, 8=1, 8-2, and 8-3 are moved in the swing angle, and the pickup rollers 4 and 4' are operated to perform a second normalization trial. On the other hand, the feed access detection unit 12 detects a tie as in #P) above. -12-〇 operates, and if the detection signal is transmitted from sensor 7 to tie blue -12-0 of c, the form is drawn normally, and if the line detection signal is not decelerated, the non-detection signal is retried.

A trial to normalize 2@ was carried out, and at the end of the trial, all the paperwork was done! I @ will be given a good balance. This fruit.

The report is above! As explained in I Haraba, it is induced to be inhaled normally.

That’s all! As explained, in the end, according to the present invention, when there is a feed error of one person such as @ vote by setting up a distribution mode, this distribution mode is used to give 11r to the medium. Even if there is a feed error in which the S body is not sucked into the feed roller, this feed error is automatically corrected and the medium is sucked into the feed loaf. Therefore, if there is a feed error, the need for correction by one person can be extremely reduced.
