Abstract

PURPOSE:To prevent double-feed and multi-feed of paper to be processed by providing a shutter, which is pressed by a sheet to be processed, which is transported to a process portion to close a sheet admission passage at a position behind the leading end portion of the sheet to be processed. CONSTITUTION:In a sticking device for sticking a laminate film on photographic paper 38 as a paper to be processed, when a sheet of photographic paper 38 is manually inserted from an insert opening, the photographic paper 38 is transported to the right by driving and driven paper feed rollers 12, 13 rotated in a designated direction. At this time, the printing paper 38 pushes up the forward end portion 23a of the lever portion 23, so that a shutter portion 22 integral with the lever portion 23 is lowered again the tensile force of a spring 24 to clamp the printing paper 38 between the lower end edge of the shutter portion 22 and a transfer guide plate 17. In such a condition, the succeeding photographic paper 38R is checked from being advanced by the shutter portion 22 to prevent double-feed of the photographic paper 38.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a novel manual paper feeding mechanism. Specifically, it is a device such as a printer or a laminator that manually feeds paper to be processed one sheet at a time. Even if a processed paper is inserted, the subsequent processed paper is not transferred directly toward the processing section, so the timing of inserting the processed paper is not restricted, improving usability and improving the ease of use. It is an object of the present invention to provide a novel manual paper feeding mechanism that can improve the efficiency of processing paper in a uniform manner and achieve such effects at low cost.

BACKGROUND OF THE INVENTION Many printers, laminators, and the like that process single-sheet paper employ a manual paper feeding mechanism.

FIG. 6 shows an example a of a conventional manual paper feeding mechanism.

In the figure, b is a driving paper feed roller, C is a driven paper feed roller, and both rollers b and c are in pressure contact with each other. d is a pressure roller, e is a heater, and both d and e are in pressure contact with each other. f is a guide board.

Thus, the driving paper feed roller b and the driven paper feed roller C are rotated in the direction shown by the arrow. Therefore, the paper to be treated (
Here, when photographic paper (g) is inserted between the driving paper feed roller b and the driven paper feed roller C, the photographic paper g is placed on the guide plate f.
The material is guided by the pressure roller d and the heater e (see FIG. 6(A)).

Problem to be Solved by the Invention However, before the processing of the previously inserted photographic paper g1 is completed, the trailing edge of the photographic paper g1 is still stuck between the driving paper feed roller b and the driven paper feed roller C. When the next photographic paper g2 is inserted while it is still on the entrance side, as shown in No. 6 (B), the leading edge of the photographic paper g2 inserted later becomes the rear end of the photographic paper g1 inserted earlier. There is a problem in that both the photographic papers g1 and g2 are transferred to the pressure roller d and the heater e in this state, and the photographic papers g1 and g2 are processed while being partially overlapped with each other.

In order to prevent this kind of double insertion, it is conceivable to turn on a lamp to let you know when it is time to insert the next paper to be processed, but it is not necessary to check that the lamp is on when inserting the next paper to be processed. Inserting paper is a hassle;
It is not easy to use and has no effect on careless operators.

In addition, in order to completely prevent the insertion of the next paper during processing, a shutter may be provided at the paper insertion slot, or a feeder consisting of a driving paper feed roller and a driven paper feed roller may be used. Part of the paper roller is set in two stages, and the part of the paper feed roller on the side of the paper insertion slot to be processed is sufficiently separated, so that during processing of the previous paper, the rear end of the paper to be processed is aligned with the paper feed roller. Although it is possible to prevent it from protruding from the part to the insertion port side, there are problems such as the mechanism becomes complicated and special circuits have to be added, which increases costs. be.

OBJECT OF THE INVENTION The present invention has been made in view of the above-mentioned problems with the conventional manual paper feeding mechanism.
A device such as a laminator that manually feeds paper to be processed one sheet at a time, and inserts the next paper while the previously inserted paper is halfway between the paper feed section and the processing section. However, the timing of inserting the paper to be processed is not restricted, which improves usability and makes it possible to handle a large amount of paper to be processed. It is an object of the present invention to provide a novel manual paper feeding mechanism that can improve processing efficiency and realize such effects at low cost.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the paper feed mechanism of the present invention is configured to feed the paper to be processed at a position behind the leading end of the paper by being pressed by the paper being transferred toward the processing section. A feature is that a shutter is provided to close the paper entrance path.

Operation Therefore, according to the inventive paper feed mechanism, 1 and Ti are first fed.
1'r? +4+u12m111 牸bu【、+＜m11f(
The paper to be processed presses the shutter and closes the paper entry path at a position behind the leading edge of the paper to be processed. The conveyance of the paper to be processed is stopped by the shutter until the previous paper to be processed stops being suppressed by the shutter, that is, until it passes the position where the shutter is pressed.
It is possible to prevent the occurrence of a situation in which two or more sheets of paper to be processed are transported toward the processing section in an overlapping state.

Moreover, since the shutter is closed by the paper to be processed that is transported toward the processing section, no special mechanism or circuit is required, and the cost does not become too high.

37 is a laminated tape wound into a roll paper. The laminate tape 37 is made of a material having a certain degree of heat resistance, and a laminate film (not shown), which is a transparent film and has a heat-activated adhesive layer formed thereon, is attached to one surface thereof. The laminate films are sized according to the shape of the photographic paper 38 (see FIG. 2), and are placed on one surface of the laminate tape 37 at a predetermined distance from each other.

Reference numeral 39 denotes a supply reel rotatably disposed at a position near the front side of the upper part of the machine frame 2;
The laminate tape 37 described above is wound around 9.

Further, reference numeral 40 denotes a take-up side reel disposed at a position closer to the rear side in the upper part of the machine frame 2, and the above-mentioned supply side reel 39
The laminate tape 37 pulled out from the laminate tape 37 is wound on the take-up reel 40 after being passed through a predetermined travel path which will be described later. Reference numeral 41 denotes a reel drive shaft with which the take-up side reel 40 is engaged so as to rotate integrally, and both ends of the reel drive shaft are connected to the side chassis 6, (6'l).
It is rotatably supported by a bearing member (not shown) provided in the.

Reference numerals 42, 42, and 42 are tape guide rollers that regulate the travel path of the laminated tape 27, and are rotatably arranged at predetermined positions.

Thus, the laminate tape 37 pulled out from the supply reel 39 is made to travel along a running path as shown by the two-dot chain line in FIG. That is, after being pulled out from the supply reel 39, it is once passed between the approximately intermediate pressure roller 7 between the drive/feed roller 12 and the pressure roller 7 and the heat generating part 19 of the heater 18, and then Paper ejection roller 28
The paper is guided toward the side, and before reaching the drive paper discharge roller 28, it is guided upward and wound onto the first winding reel 40.

When the photographic paper 38 is inserted from the photographic paper insertion slot 3, the photographic paper 38 is transferred to the pressure roller 7 side by the driving paper feed roller 12 and the driven paper feed roller 13.

During this process, the photographic paper 38 is attached to the lever part 2 of the shank 20.
3, the tip portion 23a is pressed upward, so that the shutter part 22 descends downward against the tensile force of the coil spring 24, and the gap between the lower edge of the shutter @ 22 and the transfer guide plate 17 is It will be in a state where the photographic paper is sandwiched for 3 days (
Of course, this pinched state is not strong enough to prevent the transfer of the photographic paper 38 (see FIG. 5(A)), so the rear end of the third day of the photographic paper is at the tip of the lever part 23a. Before passing the position, the next photographic paper 38R collides with the insert part 22 (see Fig. 5 CB), and as a result,
Even if the rollers 12 and 13 are sandwiched between the driving paper feed roller 12 and the driven paper feed roller 13, slipping occurs between the rollers 12 and 13 (the front (While the trailing edge of the photographic paper 38 is still present, a slip occurs between the driven paper feed roller 13 and the photographic paper 38.) It does not advance any further. When the previous photographic paper 38 passes the position of the tip 23a of the lever part 23, the force that was pressing the tip 23a upward disappears, and the tensile force of the coil spring 24 causes the shutter to close. Part 22 rises as shown in Figure 5 (
(see C)), there is no obstacle to transporting the next photographic paper 38H, so when the drive paper feed roller 12 is rotated, the photographic paper 38R is transported toward the pressure roller 7.

The photographic paper 38 transferred toward the pressure roller 7 is brought into pressure contact with the laminate tape 37 by the pressure roller 7 and the heat generating portion 19 of the heater 18, and is then transferred toward the driving paper discharge roller 28 side. Note that when the pressure roller 7 is rotated, the take-up reel 40 is rotated by a predetermined amount in synchronization with the rotation of the pressure roller 7, whereby the laminated tape 37
Since the laminate tape 37 is moved at a predetermined pitch, the laminate tape 37 is moved integrally with the photographic paper 38. As a result, the laminate film attached to the laminate tape 37 is heated by the heat generating section 19 of the heater 18, thereby activating its adhesive layer, and the photographic paper 3
8, so that it is peeled off from the laminate film 37 and adhered to the photographic paper 38.

However, the photographic paper 38 to which the laminating film was attached
The photographic paper 38 is transferred onto the paper ejection guide plate 36 by the driving paper ejection roller 28 and the driven paper ejection roller 31, and the leading edge of the photographic paper 38 transferred onto the paper ejection guide plate 36 is on the paper ejection guide. Stopper 36 formed at the rear end of the plate 36
a, it is curved as shown by the two-dot chain line in FIG.
When the paper is sent out from the exit side of the part where the paper and the driven paper discharge roller 31 come into contact with each other, ! Due to the repulsive force accumulated by the bending, the rear end comes into contact with the circumferential surface of the drive paper feed roller 28, and as the drive paper feed roller 28 rotates, it automatically connects with the drive paper ejection roller 28. It is inserted into the inlet side of the portion where the delivery roller 32 contacts each other. The photographic paper 38 is then transferred to the paper ejection port 5 side by the driving paper ejection roller 28 and the driven paper delivery roller 32, and is transferred from the paper ejection port 5 to the machine frame. being sent outside.

Note that the pressure roller 7, drive paper feed roller 12, drive paper discharge roller 28, and reel drive shaft 41 are configured to rotate in a predetermined rotation direction at a predetermined timing, and these will be explained in detail later. do.

Next, the above-described pressure roller 7 and drive paper feed roller 12 are

Reference numeral 49 denotes a sticking side gear provided at a position near the bearing member 9 in a portion of the roller heel 8 of the pressure roller 7 that protrudes from the bearing member 9 to the left side.
It is combined with No. 8. This pasting side gear 49 is meshed with the first output gear 44.

Reference numeral 51 denotes a υF paper side pulley provided on a portion of the roller shaft 29 of the driving paper ejection roller 28 that protrudes to the left from the n11 paper ejection side roller 47) liA paper ejection side pulley 51 is a fourth one-way clutch It is connected to the roller shaft 29 via 52.

Reference numeral 53 denotes a paper feeding side transmission gear, and the paper feeding side transmission gear 53 is meshed with the paper feeding side gear 45 indicated by 11i'I.
A small gear 54 integrally formed with this is the output gear 44.
It is meshed with. Thus, the rotational force of the motor 43 is transmitted to the paper feed side gear 45 via the output gear 44, the small gear 54, and the paper feed side transmission gear 53.

Reference numeral 55 denotes a paper discharge side transmission gear, and a small gear 56 is integrally formed therein. Further, 57 is an intermediate gear on the paper discharge side. The paper ejection side transmission gear 55 is meshed with the paper ejection side intermediate gear 57, and its small gear 56 is meshed with the above-mentioned clearing side gear 49, and the paper ejection side intermediate gear f57 is connected to the paper side It is meshed with gear 47. However, motor 43
The rotational force is the output gear 44 - the adhesive gear 49 - the small gear 56
It is transmitted to the paper discharge side gear 47 through a transmission path such as - discharge side transmission gear 55 - paper discharge side intermediate gear 57.

58 is a drive pulley fixed to a portion of the roller 1 drawer 8 of the pressure roller 7 that protrudes to the left from the sticking side gear 49, and 59 is a torque limiter (not shown) at the left end of the reel drive f+41. This is a reel-side pulley connected through the reel. And drive pulley 58. The reel side pulley 59 and the belt i+l'i of the paper discharge side pulley 51 are provided with gear tooth-shaped 1-gold teeth, and an endless timing belt 60 is passed around these pulleys 58, 59 and 43. ing.

Thus, the rotational force of the motor 43 is transmitted to the sticking side gear 49 via the output gear 44, and when the roller shaft 8 of the pressure roller 7 is rotated, the rotational force is transmitted to the driving pulley 58 and the timing. It is transmitted to the reel-side pulley 59 and the paper discharge-side pulley 51 via the belt 60.

By the way, in the above-mentioned Ml to fourth one-way clutches 46, 48, 50 and 52, when the motor 43 is rotated in the following rotational direction, the two clutch surfaces are integrally coupled ( Hereinafter, this state will be referred to as the "locked state".
That's what it means. ) (see Figure 4). Furthermore, the fourth
In the figure, the direction indicated by the solid line arrow indicates the direction of rotation of each gear and the pulley when the motor 43 is rotated in the normal rotation direction, and the direction indicated by the broken line arrow is the rotation direction of the motor 43 when the motor 43 is rotated in the direction of the passing force. This shows the rotation direction of each gear and pulley at the time. In addition, in the same figure, the direction indicated by the wide arrow indicates the gears 45, 47, 4 when each one-way clutch, 46, 48, 50, and 52 are in the shape of a mouth.
9 and the rotation direction of the pulley 51.

First, the first one-way clutch 46 is connected to the motor 43
When it is rotated in the normal direction, it is in a locked state. That is, the motor 43 is rotated normally and clockwise, and at this time, the first one-way clutch 46 is locked.

Therefore, when the motor 43 rotates in the forward rotation direction, the driving paper feed roller 12 is rotated counterclockwise because the rotational force is stopped.

Incidentally, when the drive paper feed roller L2 is rotated counterclockwise, the driven paper feed roller 13 in contact with it is rotated clockwise, so that both the a front rollers 12 and I3 is inserted into the inlet side of the portion that contacts TI- and I, and is transferred to the I: stamp paper 38 or river stone roller 7 side.

Next, the second one-way clutch 48 is also configured to become a long clutch when the motor 43 is rotated in the normal direction. That is, when the motor 43 is rotated in the normal direction, the paper discharge side gear 47 is rotated counterclockwise as shown by the solid line arrow, and at this time, the second one-way clutch 48 is rotated in the forward direction. .

It is said that Therefore, when the motor 43 is rotated in the forward rotation direction, the driving paper ejection roller 28 is rotated to the second detour.
It will now be able to rotate in the circular direction. Note that when the driving sheet discharge roller 28 is rotated counterclockwise, the driven roller 31 and the driven feed roller 32 that are in contact therewith are rotated in the -11 clockwise direction. As a result, the photographic paper 38 inserted into the entrance side of the drive ejection I (the part where the roller 28 and the driven paper ejection roller 31 contact each other) is transferred to the paper ejection guide plate 36 side. Imperial paper ejection roller 28 and driven delivery roller 3
2 or i that touch each other? The photographic paper 38 inserted into the R-port entrance is now transferred to the paper discharge port 5 side.

Further, the third one-way clutch 50 is connected to the motor 43.
It is designed to be in a locked state when it is rotated in the reverse direction. That is, when the motor 43 is reversed, the sticking side gear 49 is rotated counterclockwise as shown by the broken line arrow, and at this time, the third one-way clutch 50
is locked. Therefore, when the motor 43 is rotated in the reverse direction, the pressure roller 7 is rotated counterclockwise by the rotational force transmitted thereto. Furthermore, as mentioned in +iii, the heat generating part 19 of the heater 18 is in pressure contact with the pressure A roller 7.
When the pressure roller 7 is rotated, it and the heat generating part 19 of the heater 18 come into contact with each other! On the entrance side of the L-matching part (Φ), the mark III 38 is moved toward the driving paper ejection roller 28 side in synchronization with the running of the laminated tape 37.

And, the fourth one-way clutch 52 is also closed when the motor 43 is reversed.

That is, as mentioned above, when the motor 43 is reversed, the third one-way crank 50
Since the drive pulley 58 associated with the roller wheel 8 of the pressure C' roller 7 is rotated in the counterclockwise direction. As a result, the timing belt 60
is run, the reel-side pulley 59 is rotated in the winding direction, and the discharge-side pulley 51 is rotated counterclockwise as shown by the broken line arrow, and at this time, the fourth one-way clutch is rotated. 52 is in the long state. Therefore, when the motor 43 rotates in the reverse direction, the drive paper discharge roller 28 is rotated counterclockwise by the rotational force transmitted through the fourth one-way clutch 52. That is, when the motor 43 is rotated in either the forward or reverse direction, the drive paper ejection roller 28 rotates in the same direction as r, even if the transmission path is different.
It is designed to be rotated to Q+.

Therefore, the motor 43 is rotated in the IF rotation direction.

and the driven delivery roller 32 are rotated in a predetermined rotational direction, thereby feeding the photographic paper 38 to the pressure roller 7 ( ) 111, transporting it to the paper discharge guide plate 36 side, and unpacking it to the outside. Each feeding operation is performed.Furthermore, when the motor 43 is rotated in the reverse force direction, the pressure roller 7, the take-up side roll 40, the drive paper discharge roller 28, and the driven paper are rotated in the paper roll direction. As a result, the operations of adhering the laminate film to the photographic paper 38, transferring it to the paper discharge guide plate 36, and sending it out of the apparatus are performed.

61.61' is a photographic paper insertion sensor, and this photographic paper insertion sensor 61.61' detects that the photographic paper 38 has been inserted to a predetermined insertion position, and the motor 43 rotates in the normal direction according to this detection signal. It is designed to be driven.

Reference numeral 62.62' indicates a paper feed completion sensor 62.62', which detects when the photographic paper 38 is at a predetermined paper feeding position, that is, when the leading edge of the photographic paper 38 is placed between the pressure roller 7 and the plate heater 18. It is detected that the heat generating part 19 has been moved to the position where it is inserted into the inlet side of the part where they come in contact with each other, and in accordance with this detection, the forward rotation of the motor 43 is stopped and a predetermined rotation is performed. The motor 43 is made to rotate in reverse depending on the timing.

The laminate film attached to the laminate tape 29 by the film sensor 63, 63' is set to a predetermined I.
','(!You can see that it has come to the i+ position, and this detection i,
According to No. 1, the motor 43 is reversely rotated or stopped, and the motor 43 is again driven in the forward rotation.

64, 64' is a photographic paper ejection sensor, and when it is detected by this device that there is no photographic paper 38 on the paper ejection guide plate 36, the motor 43 is activated until the next photographic paper 38 is inserted. Forced to stop.

In addition, these sensors 61.61', 62.6263.6
3' and 64 and 64', for example, a so-called photo sensor consisting of a light emitter and a photoreceiver that receives the light projected from the light emitter and generates a predetermined electrical signal is used. The position of the photographic paper 38 is detected based on the presence or absence of light received by photons.

Moreover, 65 is a static elimination brush, and the laminated tape 37
This is to remove static electricity that has accumulated on the surface.

And each of the above sensors 61.61', 62.62',
63.63' and 64.64 Rotation control of the motor 43, which is performed based on detection signals from the caps, is performed by a system controller (not shown).

The operation until the print *(3s) inserted from the insertion slot 3 is sent out from the paper discharge slot 5 is performed as follows.

That is, when the photographic paper 38 is inserted from the insertion slot 3 and its leading end reaches between the photographic paper insertion sensors 61 and 61', the motor 43 is rotated in the normal rotation direction, and the driving paper feed roller 12 and the driven paper feed roller 12 are rotated in the normal rotation direction. Paper roller 13, driven paper ejection roller 28, and driven paper ejection roller 31. The driven delivery rollers 32 are each rotated in the predetermined direction. and,
In this state, the pressure roller 7 and the take-up side roll 40 are not rotated. When the photographic paper 38 is inserted into the front end of the section where the driving paper feed roller 12 and the driven roller 13 contact each other, the photographic paper 38 is pushed toward the pressure roller 7 by the rollers 12 and 13. will be transported towards.

At this time, if the previously pasted photographic paper remains on the transport path from the pressure roller 7 to the follower delivery roller 32, - at the same time as the paper is being fed as described above, The remaining photographic paper is also sent out of the apparatus.

Then, the tip of the photographic paper 38 is detected by a paper feeding completion sensor 62.
Up to 62′? When the time reaches 1, the system controller counts a certain period of time, and when the count ends, the rotation of the motor 43 is stopped. As a result, the leading end of the photographic paper 38 is inserted into the entrance side of the portion where the pressure roller 7 and the heat generating part 19 of the heater 18 come into contact with the shingle, and the driving paper feed roller 12, the driven paper feed roller 13. The rotation of the drive paper discharge roller 28, the driven paper discharge roller 31, and the driven delivery roller 32 is stopped.

When the motor 43 or the above-mentioned temperature detection sensor detects that the heat generating part 19 of the heater 18 has reached a temperature that allows the predetermined application 71,
The motor 43 is rotated. Pressure with this! 10-roller 7 and the take-up reel 40 are rotated in a predetermined direction, and the driving paper ejection roller 28, the driven paper ejection roller 31.
The rotation of the driven delivery roller 32 is resumed.

Then, the photographic paper 38 and the laminate film attached to the laminate tape 37 are rolled together and transferred to the paper discharge port 5 side at the same time for printing, and during this time, as described above, Then, the laminated film is placed on photographic paper 3.
Paste it on 8! It will be done.

Then, when the laminate tape 37 reaches approximately the midpoint between the pressure roller 7 and the drive paper discharge roller 28, the direction is changed upward at an acute angle by the tape guide roller 42, so that the laminate tape 37 and the laminate film are separated. shunted.

When the film sensor 63, 63' detects the rear end of the used photographic paper 38 and also detects that the scuminate film has aged to a predetermined level of 11°'l, the motor 43 is reversed. motor 5 is stopped, then motor 4
3 is rotated forward. As a result, the rotation of the pressure roller 7 and the take-up reel 40 is increased to +'>: I, and
The drive paper discharge roller 28, the driven paper discharge roller 31, and the driven delivery roller 32 continue to rotate, and the rotation of the drive paper feed roller 12 and the driven paper feed roller 13 is restarted. Therefore, the photographic paper 38 to which the laminated film has been pasted is transferred to the driving paper ejection roller 28 and the driven paper ejection roller 31.
The paper is guided onto the paper discharge guide plate 36, where the direction of transport is automatically reversed as described above, and the drive paper discharge roller 28 and the driven paper delivery roller 32 guide the paper from the paper discharge port 5 to the device. 1 to be sent outside.

When the motor 43 is rotated normally again, for example, as described above, as shown in FIG. 5(C), the photographic paper 38R in which the next photographic paper 38R is waiting is transferred to the pressure roller 7 side. That will happen.

Effects of the Invention As is clear from the above description, the manual paper feeding mechanism of the present invention is capable of feeding paper at a position behind the leading edge of the paper being pressed by the paper being transported toward the processing section. It is characterized by providing a shutter that closes the processing paper entrance path.

Therefore, according to the manual paper feeding mechanism of the present invention, when the paper to be processed that has been inserted first is transported toward the processing section, the paper to be processed presses the shank and the AI; Close the paper entrance path at a position behind the leading end. Therefore, the conveyance of the paper to be processed that is inserted later is stopped by the shutter until the previous paper to be processed increases the pressure of the shunter, that is, until it passes the position where the shutter is pressed. It is possible to prevent the occurrence of a situation in which two or more sheets of paper to be processed are transported toward the processing section in an overlapping state.

Moreover, since the shutter is closed by the paper to be processed that is transported toward the processing section, no special mechanism or circuit is required, and the cost is not too high.

In the above embodiment, the manual paper feeding mechanism of the present invention is
11 for distributing simulating film to R company
Techniques for ancient 27 devices 1. Although the present invention has been shown to be applied as a paper feeding mechanism, it can also be widely applied as a manual paper feeding mechanism in devices such as printers that process single-sheet paper, films, sheets, etc.
