Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sorting device for sorting a series of sheets such as recording paper discharged from an image forming apparatus.

"Prior Art" Conventionally, in an image forming apparatus such as a facsimile IJ, a large number of image recording sheets received from a destination are stacked without being allocated for each communication. Therefore, the operator has to carry out sorting operations, and if the recording paper is missorted, there is a problem in obtaining necessary information. On the other hand, there is a method to automatically sort the recording paper by moving the tray and changing the stacking position of the recording paper for each communication. There is an image forming apparatus configured to eject recording paper for different sizes in different directions and perform the sorting by this (Japanese Patent Laid-Open No. 1-92174).
Publication No.).

[Problems to be Solved by the Invention] However, with the above-mentioned method of moving the tray and changing the stacking position of the recording paper for each communication, the device becomes large and expensive, and the installation space is required due to the movement of the tray. There was a problem of having to consider margin.

On the other hand, in an image forming apparatus that uses partition paper of a different size than normal recording paper, it is necessary to separately prepare paper that is larger than the paper for image formation, and the paper supply for this paper must be prepared separately. mechanism is required, so overall a paper feed mechanism for at least two types of paper is required. However, the most popular facsimile at present is a roll paper facsimile that uses heat-sensitive roll paper to feed paper, and most of them can only load one size of roll paper, making it difficult to adopt this structure. be. Furthermore, in this image forming apparatus, the paper set as a recording paper is directly ejected as a partition paper, so the paper is wasted.

The present invention was made in view of these problems, and its purpose is to be able to sort paper with a simple structure, and to eject paper and partition paper using a single paper feed mechanism, thereby reducing waste of paper. The aim is to provide a compact and inexpensive paper sorting device that can be reduced.

``Means for Solving the Problems'' The paper sorting device of the present invention includes a carry-in section into which paper or partition paper is carried in, a discharge section which discharges the paper and partition paper carried in from the carry-in section, and the carry-in section. a partition paper transport mechanism provided between the partition paper and the ejecting section, and configured to transport the partition paper by changing its transport direction so that the ejecting position at the ejecting section is at a different position from the paper when the partition paper is carried in; and the ejecting section and a storage section that stacks and stores the sheets and partition paper discharged from the printer.

In addition, the paper sorting apparatus of the present invention uses roll paper as a supply source of paper or partition paper, and is provided with a roll paper cutting mechanism between the carry-in section and the partition paper transport mechanism, and cuts the roll paper to cut the paper. It is configured to form a partition paper together with the paper.

With this configuration, in the paper sorting apparatus of the present invention, the partition paper is fed diagonally by the partition paper conveyance mechanism,
Since the paper is ejected at a different position from the paper, the paper can be sorted with a simple configuration. In particular, when roll paper is used as a paper supply source and a roll paper cutting mechanism is installed downstream of the input section, it is possible to sort paper using one paper supply source, and also to cut the paper into lengths shorter than the paper. By using it as a partition paper, paper waste can be reduced.

"Example" Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the structure of a paper sorting apparatus according to an embodiment of the present invention, and FIG. 2 schematically shows its cross-sectional structure. This paper sorting device is provided, for example, in a recording paper ejection section of a facsimile machine that uses roll paper as a paper supply source.

In the figure, numeral 11 denotes a sheet of paper before image recording, and this sheet 11 is fed between a pressure roller 12 and a thermal head 13 for image formation, which constitute a sheet carrying section. The pressure roller 12 is rotated counterclockwise in FIG. 2 by a motor (not shown). A roll paper cutting mechanism 14 is disposed downstream of the pressure roller 12 and the thermal head 13. On the downstream side of the roll paper cutting mechanism 14, discharging rollers 15 and 16 constituting a discharging section are disposed, and on the downstream side of these discharging rollers 15 and 16, a tray 17 for storing the recording paper 11a# and the partition paper 11b is disposed. is installed. The roll paper cutting mechanism 14 cuts the paper 11 on which an image has been formed by the thermal head 13 when its leading edge reaches the nip position between the discharge rollers 15 and 16, and discharges the paper as a recording paper 11a. paper 11a
When it is necessary to sort the paper 11, for example when a series of receptions has been completed, the paper 11 is cut into lengths shorter than the distance between the roll paper cutting mechanism 14 and the nip position of the ejection rollers 15 and 16, and the paper is divided into partitions. 11b.

A transport roller 18 for transporting partition paper is disposed between the roll paper cutting mechanism 14 and the discharge rollers 15, 16.

This conveyance roller 18 is arranged obliquely by a predetermined angle α with respect to the width direction of the paper 11. Pulleys 19 and 20 are attached to the shaft 18a of the conveyance roller 18 and the shaft 12a of the pressure roller 12, respectively.
．． A belt 21 is stretched between the belts 20 in parallel. That is, the rotational force of the pressure roller 120 is transmitted to the conveying roller 18 via this winding mechanism, thereby causing the conveying roller 18 to rotate counterclockwise in FIG. 2. A pinch roller 22 is disposed below this conveyance roller 18 and parallel to this conveyance roller 18 . This pinch roller 22 is rotatably supported by one end of an L-shaped lever 24 that constitutes a link mechanism 23. The lever 24 is rotatably supported by a shaft 25 at its central bent portion. One end of a spring 26 is connected to the other end of the lever 24 . The other end of this spring 26 is fixed to the side wall of the device main body 27,
This urges the lever 24 rightward in the figure. A cut groove 28 is formed at the other end of the lever 24, and a bottle 29 is engaged with the cut groove 28.

The pin 29 protrudes from the tip of the drive end 30a of the solenoid 30. The solenoid 30 is turned off when conveying the recording paper 11a, and in this state, the lever 24 is at the position shown by the solid line in FIG. 2 due to the elastic force of the spring 26. On the other hand, when conveying the partition paper 11b, the solenoid 30 is turned on, and in this state, the lever 24 is
5 in the clockwise direction, the pinch roller 22 moves to the position shown by the broken line in FIG. 2, and rotates simultaneously with the rotation of the conveyance roller 18.

With this configuration, in the recording paper sorting apparatus of this embodiment, when the facsimile main body detects received information, the paper 11 is conveyed for a required length after the information is recorded by the pressure roller 12 and the thermal head 13. That is, when the leading end reaches the nip position between the transport rollers 15 and 16, the roll paper cutting mechanism 14 cuts the roll paper into a predetermined length and transports it as the recording paper 11a. After passing under the transport roller 18, the recording paper 11a is discharged by discharge rollers 15, 16 and stacked on the tray 17. When several sheets of recording paper 11a are stacked and the last sheet is ejected in response to a received signal, simultaneously the paper 11a
After being conveyed by a length shorter than the distance between the roll paper cutting mechanism 14 and the nip position of the discharge rollers 15 and 16, the paper roll is cut by the roll paper cutting mechanism 14, thereby forming the partition paper 11b. On the other hand, the roll paper cutting mechanism 14 outputs a cutting signal, and the solenoid 30 is turned on in synchronization with or slightly delayed from this cutting signal. When the solenoid 30 is turned on, the lever 24 rotates clockwise around the shaft 25 against the elastic force of the spring 260, and the pinch roller 22 moves upward as shown by the broken line, and the conveyor roller 18. In this state, the pressure roller 12 rotates, and this rotational force is
J19.20 and the conveyor roller 18 via the belt 21
and rotates together with the pinch roller 22. The partition paper 1 is
The conveyance direction of the recording paper 1b is switched diagonally with respect to the conveyance direction of the recording paper 11a, and in this state, the recording paper 1b is fed to the discharge rollers 15 and 16.

Thereafter, the partition paper 11b is ejected to the tray 17 by ejection rollers 15, 16 at a position shifted by δ from the ejection position of the recording paper 11a. In addition, this partition paper 11
The amount of positional deviation δ with respect to the recording paper 11a of the recording paper 11a is determined according to the magnitude of the inclination angle α of the conveyance roller 18 and the pinch roller 22 with respect to the width direction of the paper 11. The solenoid 30 is turned off when the partition paper 11b is fed to a position where it is sufficiently pinched by the ejection rollers 15, 16, and the pinch roller 22 returns to the position shown by the solid line in FIG.

Furthermore, when the ejection of the partition paper 11b is completed, the paper 11
returns to its initial position and waits.

In this way, in the paper sorting of this embodiment, in electrical manufacturing, the roll paper cutting mechanism 14 cuts the paper 11 into a predetermined length to form the recording paper 11a, and this paper 11 is cut into shorter lengths than the recording paper 11a. Since the partition paper 11b is used as the partition paper 11b, waste of paper can be prevented, especially when roll paper is used as the supply source of the paper 11. In addition, since there is no need to separately provide a paper feeding mechanism for the partition paper 11b,
The structure of the entire device is simplified. Furthermore, since the structure is such that the contact and separation operations between the transport roller 18 for transporting the partition paper and the pinch roller 22 are performed by the link mechanism 23, the recording paper 11a
It is possible to switch between conveyance of the partition paper 11b and conveyance of the partition paper 11b with a simple configuration.

In this embodiment, the conveyance roller 18 and the pressure roller 12 are
As a means for transmitting the rotational force, a mechanism is used for the winding of the belt by the two members, but as shown in FIG. 3, friction wheels 31 and 32 may be used to transmit the rotational force.

In the embodiment shown in FIG. 1, the recording paper 11a and the partition paper 1
As a feeding mechanism that shifts the ejection position from the recording paper 1b, the conveyance roller 18 and the pinch roller 22 are arranged at an angle with respect to the width direction of the recording paper 11a, as shown in FIG. 4, for example. It is also possible to have a configuration like this.

In FIG. 4, the pinch roller 41 and the recording paper 1
A discharge roller 42 for conveying the paper 1a or the partition paper 11b is moved back and forth in the width direction of the recording paper 11a. That is, the shaft 4 of the discharge roller 42
2a is supported on both sides by a U-shaped member 44 via bearing members 43, and a link member 46 constituting a link mechanism 45 is attached to the back side of the U-shaped member 44. One end of a link member 47 is rotatably connected to one end of this link member 46,
A gear 48 is attached to the other end of the link member 47. Although the shaft 48a of the gear 48 is not shown, for example, the movement of the bearing in the horizontal direction is restricted by a member or the like. A gear 49 attached to a drive shaft 50a of a motor 50 meshes with the gear 48. That is, the rotational force of the motor 50 in the forward and reverse directions is transmitted to the gear 48 via the gear 49, thereby causing the link member 47 to rotate against the shaft 4.
It is designed to swing around 8a. Ko no u member 4
4 has a pin 51 erected, and this pin 51 and the frame 5
2 is connected by a spring 53, which urges the ejection roller 42 together with the outer member 44 to the right in FIG. In addition, the shaft 4 of the discharge roller 42
2a has a pipe shape, and a drive shaft 54 is connected to one end of this shaft 42a. A drive gear 55 is attached to the drive shaft 54 so that rotational force from a motor (not shown) is transmitted to the drive shaft 54 via the drive gear 55 and then to the discharge roller 42 . A long groove 56 is formed along the longitudinal direction of the shaft 42a, and a stopper pin 57 fixed to a frame (not shown) projects into the long groove 56. In other words, the discharge roller 4
2 is capable of reciprocating left and right by the length of the long groove 56. The structure of the carry-in section and the roll paper cutting mechanism 14 is the same as that of the sorting apparatus shown in FIG. 1, so a description thereof will be omitted.

In the paper sorting apparatus of this embodiment, when ejecting the recording paper 11a, the ejection roller 4 is used as shown in FIG.
2 is located at the right end along with the U member 44 due to the elastic force of the spring 530.

When the conveyance of the recording paper 11a is completed and the partition paper 11b is finally discharged, the motor 50 rotates in the clockwise direction in the figure. This rotational force is transmitted to the link member 47 via the gears 49, 48, and the link member 47 swings counterclockwise around the shaft 48a.

As a result, the conveying roller 42 and the U member 44 resist the elastic force of the spring 53, and the pin 57 moves into the guide groove 5.
Move to the position where it engages the right end of 6. After that, the partition paper 11b is discharged by the discharge roller 42 at this position,
Sorting is done. FIG. 5 shows how the recording sheets 11a are sorted by the partition paper 11b.

The paper sorting device of this embodiment has a simple structure,
Similar to the embodiment shown in FIG. 1, the recording paper 11a can be sorted.

Note that in both the embodiments shown on the right in FIG. 1 and in FIG. On the other hand, if a weaving mark is printed or a different color from the recording paper 11a is used, the sorting can be performed more effectively. Also,
Although the size of the partition paper 11b is smaller than the recording paper 11a, it may be the same size as the recording paper 11a, or the size of the recording paper 1
Of course, it may be larger than 1a. Further, in the embodiment described above, a roll paper cutting mechanism 14 is provided downstream of the pressure roller 12 and the thermal head 13, and cuts the paper 11 into the recording paper 11a and the partition paper 11.
This is especially suitable when roll paper is used as the paper supply source, but the present invention is not limited to this, and the invention is particularly suitable for cutting cut paper without providing the roll paper cutting mechanism 14. It may also be applied to sorting.

Further, in the above embodiment, the recording paper 11a is used as paper.
As described above, the target of sorting is not limited to the recording paper 11a, but may also be paper on which no images are recorded, and in the case of the recording paper 11a, the recorded content may be sorted by numbers, etc. Of course, it is possible.

"Effects of the Invention" As explained above, according to the paper sorting apparatus according to claim 1, the partition paper is fed diagonally by the partition paper conveyance mechanism,
Since the paper is ejected at a position shifted from the paper, the paper can be sorted with a simple structure, and a small and inexpensive paper sorting device can be provided.

Further, according to the paper sorting apparatus according to claim 2, roll paper is used as a paper supply source, and a roll paper cutting mechanism is provided on the downstream side of the carry-in section, and sheets and partition paper are formed by cutting the roll paper. By doing so, the number of paper supply sources can be reduced to one, thereby making it possible to downsize the entire apparatus. Further, especially by forming the partition paper to have a length shorter than the paper, waste of paper can be reduced.
