2. Description of the Related Art Conventionally, EP 0407795B1 is known as a technique relating to a paper sheet stacking apparatus for stacking conveyed paper sheets, which touches the structure of a member for stopping the paper sheets. . In this paper sheet stacking device according to the prior art, there is shown a structure in which a member that stops upon collision of paper sheets is provided with an inclined member that travels to the side where the paper sheets are stacked. With this inclination member, the paper sheets are pressed against a member having the same inclination, which is attached to the frame on the back side, and the paper sheets are inclined and aligned and accumulated.

[0003]

SUMMARY OF THE INVENTION The above-mentioned paper sheet stacking device stacks paper sheets while tilting them with respect to the transport direction, and takes out the stacked paper sheets obliquely with respect to the transport direction. With the one described in this prior art, there is not much problem because there is a margin in the transport direction of each sorting shelf, but when reducing each sorting shelf to reduce the size of the entire device, the paper sheets on the opposite side of the sheet transporting direction are Since the wall is tilted with respect to the stacked paper sheets and the collision plate is tilted toward the inside of the sorting shelf, the thickness of the tilting member greatly affects the ease of taking out the stacked paper sheets. However, there was a problem that the frontage became narrow and it was difficult to take out.

It is an object of the present invention to provide a paper sheet processing apparatus which is not difficult to take out even if each sorting shelf is downsized.

[0005]

[Means for Solving the Problems] The above-mentioned object is to convey a sheet to convey a sheet, introducing means to selectively introduce the sheet conveyed by the conveying means, and the introduced sheet. In the paper sheet stacking device, which is provided with a stacking container having a wall surface in the traveling direction having a function of colliding and accumulating the tips of the leaves and a wall surface on the side opposite to the take-out side of the wall surface, the introduced paper sheet. This is achieved by providing a convex portion on the wall surface in the traveling direction such that the paper sheet take-out side collides with the center of the leading edge of the leaf.

[0006] Further, the purpose is to convey a sheet, a reading unit for reading the sorting information of the sheet, a stacking unit for stacking the sheets, and one side of the sheet. In a paper sheet processing apparatus provided with a aligning unit that adjusts the posture by conveying along an aligning reference plane made of a belt or a plate, the aligning reference plane is provided on the upstream side of the reading unit. A first alignment unit that is parallel to the transport direction of the transport unit, and is provided between the reading unit and the stacking unit, and the alignment reference plane is the alignment reference plane with respect to the transport direction of the transport unit. It can also be achieved by providing a second aligning means that is inclined on the upstream side of the stacking means so as to travel to the paper sheet take-out side of the collecting means.

[0007]

1 is a schematic view of a letter sorter which is an embodiment of a paper sheet processing apparatus of the present invention. The paper sheets handled by the apparatus of this embodiment are regular postal letters such as postcards and envelopes.

The letter sorter 50 shown in FIG. 1 reads not only the postal code written on the letter but also the address, and prints the information as a bar code on the letter to process the letter. Therefore, the separator 1 for separating the letters one by one, the detection unit 2 for detecting the double feeding and the thickness of the letters, and the alignment unit 3 for correcting the skew and shift of the letters.
Besides, a reading unit 4 for reading a postal code and an address,
A printer 5 for printing a barcode and barcode reading units 6 and 12 for reading the barcode are provided. As the printer 5 that prints barcodes, an ink jet printer is used to print letters in various thicknesses and materials.

There are two types of sorting machines, an offline type and an online type, for recognizing a postal code or an address and printing a bar code. In the sorting machine of FIG. 1, a letter whose address cannot be read is temporarily used. This is an off-line type in which an ID code is added to eliminate the ID code, and another device is used to perform classification again. Of course, the present invention is not limited to the off-line type letter sorter.

Next, the flow of letters in the letter sorter shown in FIG. 1 will be described. The letters 8 set in the hopper 7 of the letter sorting machine are separated by the separator 1 one by one. The letters separated one by one are double-fed by the detector 2 in order to prevent misclassification of letters and obstacles during transportation in advance, and bending rigidity of letters.
(Hardness) and the thickness of the letter are detected. A letter having a large bending rigidity (hardness) or a letter having a thickness larger than a predetermined value is detected by the detection gate 2 at the conveyance gate 9 on the downstream side of the detection portion 2. It is switched and loaded into the reject box 10.

A letter which is not considered to be abnormal by the detection unit 2 is conveyed to the alignment unit 3 to correct skew and shift.
In order to normally read the address reading unit 4 and the bar code reading unit 6 on the downstream side of the alignment unit 3,
It is provided so that the posture of the letter is corrected and the printing position of the barcode matches the position of the reading sensor.

The letter 8 that has passed through the alignment unit 3 is read by the address reading unit 4 first of the zip code and the address, and then by the bar code reading unit 6 provided on the downstream side of the letter 8 by the sender or another station. The barcode attached to is scanned.

With respect to the letter to which the barcode is not attached, the barcode is printed at the position of the letter determined by the ink jet printer 5 based on the information read by the address reading unit 4.

The letter on which the barcode is printed is read by the barcode reading section 12 on the downstream side of the printer 5. The bar code information switches the gate 14 or a partition gate (not shown) provided above the partition shelf 13 so that the letters are collected on a predetermined partition shelf 13. The letter whose address could not be read is provided with an ID code and is conveyed to the reject section 13A.

In the sorting machine of FIG. 1, the bar code reading unit 1
On the downstream side of 2, there is provided a letter-shaped overlapping conveyance path 15 including two long and short conveyance routes. This improves the reliability of stacking by stacking two subsequent letters on the preceding letter and stacking two letters on the partition shelf when two letters are stacked on the same partition shelf. It is for. That is, normally, the letter is conveyed on the longer conveyance path 15A of the letter overlapped conveyance path, but when the letters are overlapped, the succeeding letter is conveyed on the shorter conveyance path 15B and the preceding letter is conveyed. On top of. By stacking letters in this manner, when letters are successively accumulated on the same section shelf, a jam caused by a subsequent letter colliding with a preceding letter is prevented.

A transport path 16 for transporting a letter to the partition shelf is provided at the upper part of each stage of the partition shelf 13. The conveying means is endless belts 17A and 17B which are opposed and contact with each other to pinch and convey the letter. These transport belts 17 are rotated by a driving force transmitted from a transport belt drive motor (not shown). Also, the frame 18
Is erected so that its upper part is inclined so as to be separated from the operating side. The section shelf 13 and the transport path 16 are the frame 1
8 is fixed.

The detailed structure of the side surface of the dividing shelf 13 is shown in FIG. In the figure, for clarity, the letter 8 that is being introduced and the plurality of accumulated letters 58 that have already been accumulated are also shown. The partition shelf 13 is a frame body 10 that constitutes a part of a stacking container that stacks the letters 8 in a substantially horizontal state.
1 and a sorting gate 102 that is provided in the vicinity of the transportation path 16 and switches the transportation direction of the letter 8 that has been transported, and is provided downstream of the sorting gate 102 in the transportation direction and provided near the sorting gate 102. The section guide 103 swings around the fulcrum S.

The frame 101 includes a downstream side plate 101a, which is a plate member provided substantially downstream from the sorting guide 103 in the transport direction, and a downstream side plate 101a upstream from the sorting guide 103 in the transport direction. The upstream side plate 101b, which is a plate member provided in parallel, and the bottom plate 101c provided substantially parallel to the transport path 16 between the downstream side plate 101a and the upstream side plate 101b. It is fixed at 18. The frame 101 and a part of the frame 18 that is in contact with the inside of the frame 101 form an integrated container. The surface of the stacking container facing the frame 18, that is, the surface on the front side is open for taking out the stacking letters 58. Hereinafter, this is called an opening.
Note that the sorting gate 102 and the sorting guide 103 are letters 8
And an introducing means for introducing into the collecting container.

FIG. 2 shows a detailed structure near the downstream side plate 101a.
3 is a top view of the partition shelf 13 as seen from the arrow B in FIG.
This will be described with reference to FIG. The transport path 16 is not shown in order to clarify the structure. The side A of the letter 8 on the frame 18 side is conveyed by the conveyance path 16 along the reference conveyance surface L. The downstream side plate 101a serves as a stop member that stops the letter 8 that has been introduced (loaded) into the frame body 101. A biasing plate 105 for aligning and stacking the letters 8 in the sorting shelf 13 is provided on the upstream side of the downstream side plate 101a in the transport direction.

The shape and position of the urging plate 105 will be described.
In the present embodiment, the urging plate 105 has a plate-like rectangular parallelepiped shape having a width W, a height H, and a thickness T. The position where the urging plate 105 is attached is the distance D from the urging plate 105 to the intersection C between the downstream side plate 101a and the conveyance reference plane L, and D is the range from the center of the side of the leading edge of the letter to the takeout side. It is in. The angle θ is the downstream side plate 101a and the tangent line N connecting the corner E and the intersection C on the frame 18 side on the upstream side in the transport direction.
It is an angle formed by. Further, a distance P is separated between the transport reference plane L and the frame 18.

Next, the action and effect of the biasing plate 105 will be described with reference to FIG.
It will be described with reference to FIGS. 4 to 6 are top views of the dividing shelf 13 shown in FIG. 2 as seen from the arrow B. In order to explain the operation of the urging plate 105, a letter when the urging plate 105 is not installed is shown. 8 shows the behavior when 8 collides with the downstream side plate 101a. 8a shows the state immediately before the letters collide, 8b shows the state after the letters collide, and G shows the center of gravity of the letter 8. In the state 8a of FIG. 4, the corner J of the leading edge of the letter 8 on the frame 18 side
The state (a side opposite to the opening of the letter 8) collides first and the state 8a in FIG.
In the state 8a of FIG. 6, the edge K of the edge of the leading edge of the letter 8 (the opening side of the letter 8) first strikes the edge of the letter 8 that is substantially parallel to the downstream side plate 101a. It shows the case of collision. Here, the angle between the letter 8 and the downstream side plate 101a in the state 8a is ψ, and the counterclockwise direction is positive in the top view seen from the arrow B in FIG. That is, the state shown in FIG. 4 is positive, and the state shown in FIG. 6 is negative.

When the corner J on the frame 18 side first collides as shown in FIG. 4, the reaction force from the downstream side plate 101a acts on the frame 18 side from the center of gravity G of the letter 8.
A clockwise rotational force M is generated on the letter 8. as a result,
The letter 8 has the rear end protruding toward the opening as in the state 8b. Further, as shown in FIG. 5, the letter 8 is in the state 8a.
When the edge side and the downstream side plate 101a collide with each other in a substantially parallel manner as described above, the reaction force from the downstream side plate 101a acts in the vicinity of the center of gravity G of the letter 8, and thus the letter 8 is in the reverse direction of the conveyance direction. Bounce back to. As a result, the tip is separated from the upstream side plate 101a as in the state 8b. Further, as shown in FIG. 6, when the corner K on the opening side first collides, the downstream side plate 1
Since the reaction force from 01a acts on the opening side from the center of gravity G of the letter 8, a counterclockwise rotational force M ′ is generated in the letter 8.
Therefore, the letter 8 is pressed against the frame 18 as in the state 8b and stops along the frame 18 while the speed is attenuated by friction. The above phenomenon will be described from the measurement result of the speed change of the letter before and after the collision.

In FIG. 7, the speed V1 in the transport direction before the letter 8 collides with the downstream side plate 101a and the speed V2 in the transport direction after the letter 8 are measured, and the speed ratio R is R = V2 / V1. It is the graph obtained by arranging the collision angle ψ as the abscissa and the speed ratio R as the ordinate, and drawing an approximated curve. Also, ψ1 <0 °. In the state shown in FIG. 5, the region β is a region where the leading edge of the letter 8 collides with the downstream side plate 101a substantially in parallel, and the rebounded letter 8 does not rotate much and bounces in the direction opposite to the transport direction. Therefore, the speed ratio R shows the largest value. In the area γ shown in FIG. 4, the area J on the frame 18 side collides first,
In the state shown in FIG. 6, the area α is an area where the corner K on the opening side first collides. Since the rotational force M is generated in the region γ, the speed ratio R is smaller than in the region β, but R is larger than in the region α because there is no friction between the frame 18 and the letter 8.

In the area α, the speed ratio R becomes smaller than a predetermined value, and the leading end of the letter 8 stops near the downstream side plate 101a. Further, the letter 8 is pressed against the frame 18 and thus stops along the frame 18. As a result, if the letter 8 collides with the downstream side plate 101a under the condition of the region α, it is considered that the two sides of the letter can be accumulated (deposited) in a state where the two sides of the letter are substantially aligned with the downstream side plate 101a and the frame 18.

Therefore, the edge of the letter 8 is the side plate 1 on the downstream side.
Even if it is introduced in a state parallel to 01a, it is sufficient to incline the downstream side plate 101a in advance so that the collision occurs under the condition of the region α. As an example thereof, the urging plate 105 is attached to the downstream side plate 101a so as to collide in the range of the angle ψ <ψ1.
And the angle θ> | ψ1 | in FIG. 3 is considered.

On the other hand, the side of the leading edge of the letter 8 is the downstream side plate 10.
It may be introduced with an inclination with respect to 1a.

The cause of this is that, for example, when it is sequentially supplied from the separating unit 1, it is sent out at an inclination, or it cannot be completely corrected by the aligning unit 3. The range of inclination of this letter 8 is set to ± σ. The range ± σ includes those that have a particularly large inclination for some reason, for example, those that are inclined due to extreme uneven distribution of the contents of the letter, inclusion of foreign matter, catching on the transport path, etc. Instead, the variation range of the predetermined inclination obtained by the separation unit 1 and the alignment unit 3 is set.

Here, the urging plate 105 with the angle θ = | ψ1 |
Then, as indicated by the range A in FIG. 7, ψ1-σ <ψ <ψ1
The letter 8 collides with + σ. Therefore, collision may occur in the area β, and the way of aligning the letters deteriorates. Therefore, the angle θ =
If | ψ1-σ | is set so that the variation in the inclination of the carry-in of the letters is ψ1-2σ <ψ <ψ1 in the range B, all the letters 8 can collide with the downstream side plate 101a in the region α.

By this, the letters 8 can be aligned and collected. Further, it can be seen from FIG. 7 that the angle θ is determined by the value on the + side of the range ± σ. The physical meaning of the + side of this range ± σ is the inclination of the side of the leading edge of the letter 8 in the direction in which the frame side travels (see FIG. 4), and the angle K on the opening side of the letter 8 collides first. Therefore, it is necessary to increase the angle θ as the + side inclination + σ increases. Therefore, in the present embodiment shown in FIG. 3, the angle θ = | ψ1-σ |
A biasing plate 105 for realizing the above is provided.

By the way, in recent years, there has been a demand for miniaturization of the mail sorting device, and for that purpose, it is necessary to make the opening small. In the former case of the above-mentioned prior art, since the opening is comparatively wide, it did not cause a problem, but when the opening becomes smaller due to the downsizing of the sorting apparatus, the tilting member 106 in this prior art becomes closer to the opening side. Since the thickness T ′ becomes large, the width is gradually narrowed when the bundle of letters is taken out, and the letters are scratched, and it becomes difficult to take out the letters. Furthermore, this reduces the margin for the passage area required to pull out the paper sheets, and may be significantly difficult to take out if the thickness T ′ of the inclined member is large.

Therefore, the structure of the urging plate 105 which has the effect of reducing the thickness T and facilitating the stacking of the letters 8 in order to make it easier to take out the stacked letters 58, will be described below. First, the position of the corner E in FIG. 3 is on the tangent line N of the angle θ = | ψ1-σ | in FIG. 3 in order to fit the variation range of the letter in the area α in FIG. 7. Then, the distance D is set in a range from half of the maximum width of the letter 8 to the minimum width of the letter 8 so that the corner E is closer to the opening than the center of gravity of the letter 8. A biasing plate 105 constituted by a surface substantially parallel to the downstream side plate 101a was provided from there to the opening side.

The effect that the letters 8 are gathered together by the biasing plate 105 having this shape will be described with reference to FIG.
The letter 8 collides with the downstream side plate 101a provided with the urging plate 105 and bounces off. In state 8a, corner E
Is in the range closer to the take-out side than the center of the side of the leading edge of the letter 8, and is therefore closer to the opening than the center of gravity G of the letter 8 handled by this apparatus. Therefore, the reaction force from the angle E causes the letter 8 to generate a counterclockwise rotational force M ′. And in the state 8b,
The letter 8 is pressed against the frame 18 and the speed is reduced,
And it stops along the frame 18. On the other hand, the bias plate 10
5, the angle θ = | ψ1-σ | is realized, so that even if the inclination of the letter 8 to be introduced varies in the range ± σ, the letter collides with the downstream side plate 101a in the range of the area α shown in FIG. Therefore, the letters 8 can be aligned and collected.

Further, in the above embodiment, the urging plate 105 is used.
Although a rectangular parallelepiped is used, as shown in FIG.
1a, a biasing plate 10 including a surface 105'a substantially parallel to the surface 1a and an inclined surface 105'b connecting the downstream side plate 101a and the corner E.
If it is set to 5 ', even if the tip of the letter 8 has a shape such that it is easily torn, the tip is less likely to be caught in the corner E, and can be easily taken out. Further, the angle τ formed by the inclined surface of the urging plate 105 ′ and the downstream side plate 101a is preferably τ = θ because the smoother the angle E is, the more the prevention of catching.

Since the letter 8 collides with the urging plate 105, noise is likely to be generated. Therefore, noise can be reduced by using a material having a large damping coefficient such as a liquid crystal polymer or polyacetal so as to absorb vibration due to collision. Further, when the structure is filled in the interior, the noise is eliminated and the noise can be further reduced.

In the above embodiment, the letters are aligned by using the urging plate 105. Next, the urging plate 10 is particularly used.
A description will be given of an embodiment in which 5 are not provided on each of the divided shelves 105, but they are arranged. In the conventional paper sheet aligning device for aligning the variation of the transport angle of the letters to be transported, as described in JP-A-62-180844, the transporting means approaches the frame as it becomes downstream in the transport direction. It has a structure. It is described that the conveyance means is arranged so as to gradually approach the frame serving as the reference surface, and the conveyed paper sheets come into contact with the frame to adjust the posture of the paper sheets. As shown in the top view of FIG. 10, the aligning section 3 includes the inclined transport means 216 and the aligning frame 21.
8 and. The alignment frame 218 is a plate material parallel to the frame 18, and has the same surface as the transport reference plane L shown in FIG. Therefore, the alignment frame 21
8 is located at a position where a business trip was made from the downstream frame 18b to the conveyance path side by an interval P. Further, the inclined conveyance means 216 is configured such that the downstream side is closer to the alignment frame 218 than the upstream side. The letter 8 is a transport path 16 on the upstream side of the alignment section 3.
It is supplied from a and discharged to the downstream transport path 16b.
It is desirable that the letter 8a conveyed through the conveying path 16a on the upstream side is conveyed in such a manner that the side of the letter 8 adjacent to the frame 18 is parallel to the conveying direction. Therefore, it may be conveyed in an inclined state with respect to the conveying direction. In the inclined conveyance means 216, the letter 8a is pressed against the alignment frame 218 while being brought close to it so that the side of the letter 8a close to the frame 18 is substantially parallel to the frame 18. Then, the transport path 18
By sending out to b, the carrying direction is parallel to the frame 18 along the reference carrying surface L.

Here, as described with reference to FIG. 7, it has been found that the letters 8 are collected together when the corner K of the letter 8 on the opening side collides first. Therefore, the division shelf 13
On the upstream side, the angle K on the side of the opening of the letter 8 may be inclined in advance so that it collides first.

Therefore, an example of the second embodiment is shown in FIG.
As shown in FIG. 1, the frame 18a on the upstream side and the frame 18b on the downstream side of the aligning unit 3 remain parallel to each other, and the aligning frame 218 is angled to the transport path 16 side on the upstream side in the transport direction.
Tilt by | ψ1-σ |. And the upstream frame 1
8a is located on the letter extraction side from the upstream side of the alignment frame 218, and the frame 18b is spaced from the downstream side of the alignment frame 218 on the opposite side to the letter extraction side. Further, the inclined conveying means 216 is configured such that the downstream side is closer to the alignment frame 218 than the upstream side. It should be noted that the force with which the inclined conveying means 216 holds a letter is set to be smaller than the force with which the downstream conveying path 16b holds a letter.

In the aligning section 3 having such a configuration, the letter 8a is pressed against the aligning frame 218 and follows the aligning frame 218, so that the letter 8a passes through the inclined conveying means 216 at an angle θ with respect to the frame 18b. Then, the transport path 16
The sheet is sent to the section b and is introduced to the sorting shelf 13 in a state of being inclined at an angle θ with respect to the conveying direction. By this, division shelf 1
Even if the downstream side plate 101a of No. 3 is provided substantially perpendicular to the frame 18 and the urging plate 105 is not provided, the angle K first collides with the downstream side plate 101a, so that the stack of the integrated letters 58 can be easily taken out without being caught. Become.

Further, in the second embodiment, the alignment frame 218 is made of a plate material. However, in the letter, the rigidity is low, and the corner portion may be broken by the frictional force which comes into contact with the plate material. Therefore, as shown in FIG. 12, it is preferable that the surface with which the letter 8 comes into contact is the alignment belt 219 and the surface with which the letter 8 comes into contact is moved in the transport direction.

When the reading unit 4 reads the section information of the letter 8, the letter 8 may not be read unless the side of the letter 8 on the frame 18 side is substantially parallel to the transport direction. In this case, as shown in FIG.
And 3'can be provided. The alignment unit 3 has a configuration in which the alignment frame 218 and the frame 18 as shown in FIG. 10 are substantially parallel to each other, and when the letter 8 arrives at the reading unit, the side of the letter 8 on the frame 18 side corresponds to the conveyance direction. Make them approximately parallel. on the other hand,
The orienting unit 3'is an orienting frame 218 as shown in FIG.
And the frame 18 form an angle of θ. As a result, the downstream side plate 101a of the dividing shelf 13 is attached to the frame 1
Since the corner K first collides with the downstream side plate 101a without providing the biasing plate 105, the stack of the integrated letters 58 can be easily taken out.
