Abstract

PROBLEM TO BE SOLVED: To provide a paper sheet accumulating device capable of supporting paper sheets even if a quantity of accumulating paper sheets increases. SOLUTION: A plate 21 arranged on the back face side of a guide plate 5 rotates, and a blade of the plate 21 overhangs to the surface side from a window 8. The height of the blade overhanging from the window 8 changes according to rotation. Inputted mail reaches up to a side surface plate 3 by rotation of the plate 21. A bottom surface plate 2 inclines so that a position for arranging the guide plate 5 becomes higher than the opposite side edge 53. A support plate 4 receives gravity of the accumulated paper sheets by this inclination. A wire 16 is kept in a state of being stretched between a holding sliding part 7 and a wire installing part 17, and when the support plate 4 moves by the gravity of the paper sheets, springs 14 and 15 are extended. The spring 14 stops the extension when a running block 12b strikes on a stopper 18, and only spring 15 extends thereafter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet stacking apparatus, and more particularly to a paper sheet stacking apparatus for stacking paper sheets in a standing state.

[0002]

2. Description of the Related Art At a post office or the like, a paper sheet stacking device for stacking mail items is used. Fig. 7 shows the actual Kaihei 1-
FIG. 13 is a perspective view showing an example of a paper sheet stacking device described in Japanese Patent No. 132643. The paper sheet 180 includes the belts 181 and 1
The belts 181 and 182 are sandwiched by 82, and are conveyed between the support plate 104 and the stacking roller 105 as the belts 181 and 182 circulate. As the number of paper sheets 190 accumulated between the supporting plate 104 and the accumulating roller 105 increases, the supporting plate 104
Moves away from the collecting roller 105.
Hereinafter, the paper sheets accumulated in the paper sheet accumulating device will be referred to as accumulated paper sheets.

A constant force is applied to the support plate 104 in the direction of the accumulating roller 105. The support plate 104 sandwiches the stack of paper sheets 190 between the support plate 104 and the stacking roller 105 when a force is applied in the direction of the stacking roller 105, and supports the stack of paper sheets 190 from falling. On the other hand, stack paper 1
90 leans against the support plate 104 and accumulates while standing. As the amount of the accumulated paper sheets 190 increases, the holding sliding portion 107 moves along the guide rod 106. As means for applying a constant force to the support plate 104, for example, a constant force is applied to the support plate 104 by pulling the holding sliding portion 107 with a weight or a constant weight spring (not shown in FIG. 7). . It should be noted that the constant weight spring is a spring that has a constant force for returning to the original length regardless of the expansion of the spring.

Further, the paper sheet 180 conveyed between the stacking roller 105 and the support plate 104 moves until the leading end 180a reaches the side plate 103 by the rotation of the stacking roller 105. Therefore, the accumulated paper sheets 190
Are accumulated with the tips 190a aligned on the side surface plate 103.

When the sheet 180 is conveyed between the stacking roller 105 and the support plate 104, it is preferable that the leading end 180a does not hit the end 190b of the stacked sheet 190. Therefore, there is a case where a belt (not shown in FIG. 7) is provided on the bottom plate 102 and the belt is circulated to press the accumulated paper sheets 190 against the support plate 104. FIG. 8 is an explanatory diagram showing a state in which the accumulated paper sheets 190 are pressed against the support plate 104 by the belt. The belt 191 is attached so as to take in the bottom plate, and on the bottom plate 102, the accumulation roller 105 to the support plate 10 are provided.
Go around in the direction of 4. The accumulated paper sheets 190 accumulated while standing on the belt 191 are pressed against the support plate 104 by the belt 191. As a result, the leading end 180a of the conveyed paper sheet 180 is less likely to hit the end 190b of the accumulated paper sheet 190 and is smoothly accumulated.

[0006]

A belt 191 is attached to the bottom plate 102, and the accumulated paper sheets 1 are attached by the belt 191.
When the 90 is pressed against the support plate 104, the belt 19
A motor or the like for driving 1 is required. In order to simplify the configuration of the paper sheet stacking device, the belt 191 and the belt 1
It is preferable not to use a motor or the like for driving 91.

The support plate 104 is a stacking roller 105.
The accumulated paper sheets 190 are supported by applying a constant force in the direction of. Since the force applied to the support plate 104 in the direction of the stacking roller 105 is constant, the support plate 104 supports the stack paper sheets 190 with a constant force even if the stack paper sheets 190 increase. On the other hand, the stack of paper sheets 190 is the support plate 1.
The force of leaning toward 04 becomes larger as the number of accumulated paper sheets 190 increases. Therefore, stack paper 1
When the force by which 90 leans toward the support plate 104 becomes larger than the force by which the support plate 104 tries to support the stack of paper sheets 190, the support plate 104 cannot support the stack of paper sheets 190 and thus the stack of paper sheets 190. Class 190 falls down.

Further, the paper sheets 180 stop moving when the leading end 180a reaches the side plate 103, and the accumulated paper sheets 1
Although accumulated as 90, the accumulation roller 105 continues to rotate. For this reason, the paper sheet that has stopped moving is in contact with the rotating stacking roller 105 until the next paper sheet is conveyed. However, it is preferable that the contact time with the collecting roller 105 is short.

It is an object of the present invention to provide a paper sheet stacking device capable of stacking paper sheets while standing with a simple structure. Another object of the present invention is to provide a paper sheet stacking device capable of supporting the stacked paper sheets in a standing state even if the number of stacked paper sheets increases. Another object of the present invention is to provide a paper sheet stacking device capable of shortening the time during which a rotating member makes contact with the stack of paper sheets.

[0010]

A paper sheet stacking apparatus according to the present invention is a paper sheet stacking apparatus for stacking paper sheets in a standing state, and stacking paper sheets to be loaded in a standing state. By rotating the bottom plate and the side plate that stops the movement of the paper sheets that are loaded on the bottom plate, the rotation of the side plate intermittently contacts the paper sheets that are loaded, and the side plates Of the plate, a support member that faces the plate and prevents the paper sheets that are loaded in a standing state from falling on the bottom plate, and the distance between the support member and the plate is changed. A guide rod for moving the support member to
A spring member for pulling the support member toward the plate is provided, and the bottom plate is inclined so that paper sheets inserted in a standing state are inclined toward the support member.

The spring member is a spring member in which the force for restoring the original length increases as the elongation increases.
According to such a configuration, even if the amount of accumulated paper sheets increases, it is possible to prevent the supporting member from supporting the accumulated paper sheets and tilting the accumulated paper sheets.

Further, it is preferable that the supporting member is pulled toward the plate by a plurality of spring members having different strengths. With such a configuration, even if one spring member cannot support the stacked paper sheets, the other spring members can support the stacked paper sheets, and thus the stacked paper sheets are collapsed. Can be prevented.

The paper sheet stacking device includes, for example, a wire having one end attached to the support member and the other end fixed in a fixed position, and a movable pulley on which the wire is hooked, and the spring member is the movable pulley. Is pulled to pull the support member toward the plate. Further, it is preferable that a plurality of spring members having different strengths are provided, the wire is hung on the plurality of moving pulleys, and each spring member is configured to pull the supporting member toward the plate by pulling each moving pulley. Further, it is preferable to provide a stopper portion that limits the moving distance of the moving pulley that is pulled by the wire and moves. With such a configuration, the moving distance of the movable pulley is limited, and the other spring members support the accumulated paper sheets, so that the accumulated paper sheets can be prevented from falling down.

The plate has, for example, one or a plurality of blades, and each blade comes into contact with the paper sheets. The tip of the blade provided in the plate may be bent in an L shape.

A guide plate is provided between the rotary shaft of the plate and the support member to prevent the fed paper sheets from advancing in the direction of the rotary shaft of the plate. It is preferable to provide a window portion that overhangs. With such a configuration, the paper sheets do not advance in the direction of the rotation axis of the plate, and the paper sheets can be smoothly accumulated.

It is preferable that the bottom plate is inclined so that the side on which the paper sheets are put is higher than the side on which the side plate is provided. With such a configuration, it is possible to reliably pull in the inserted paper sheets to the side plate by the plate.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. Here, a case will be described as an example where postal items are conveyed as sheets and accumulated in a sheet accumulating device. FIG. 1 is a perspective view showing a mail stacking device which is an example of a paper stacking device according to the present invention. The mail collecting device includes a bottom plate 2 for collecting mail, a side plate 3 for supporting the mail from falling from the bottom plate 2, and a supporting plate for supporting the mail accumulated in a standing state so as not to fall. 4 and a guide plate 5 for guiding the conveyed mail items to the inside of the mail collecting device.
With. The guide plate 5 and the support plate 4 are provided so as to face each other, and the guide plate 5, the support plate 4, and the side plate 3 surround the space on the bottom plate 2 from three directions. The side plate 3, the support plate 4, and the guide plate 5 stand upright with respect to the bottom plate 2.
The postal matter 80 is put on the bottom plate 2 from the side opposite to the side plate 3, and is accumulated in the space surrounded by the guide plate 5, the support plate 4, and the side plate 3. The postal matter 80 is put in in a standing state and accumulated in a standing state. Hereinafter, the accumulated mail items will be referred to as accumulated mail items. Also, the guide plate 5
The side of the side plate 3 facing the space for accumulating mail is referred to as the surface. Also, the surface opposite to the space for accumulating mail is referred to as the back surface. FIG. 2 is a perspective view showing an example of the back surface side of the side plate 3.

The postal matter 80 is held in a standing state by being sandwiched between two belts 81 and 82 as shown in FIG. Then, the belts 81 and 82 rotate around the postal matter 80 so that the postal matter 80 is conveyed.

In the bottom plate 2, the apex 60 is apex 61.
It is placed higher than. Similarly, the apex 63 is arranged at a position higher than the apex 62. By arranging in this way, the bottom plate 2 is inclined such that the side 50 on the side where the mail is put is higher than the side 51 on the side where the side plate 3 is provided. Further, the apex 62 is arranged at a position higher than the apex 61. Similarly, the vertex 63 is the vertex 60
It is placed higher than. By arranging in this way, the bottom plate 2 is inclined so that the side 52 on which the guide plate 5 is provided is higher than the side 53 on the opposite side.

The guide plate 5 is a bent flat plate. The guide plate 5 is arranged between the rotation shaft of the plate 21 and the support plate 4. Further, the guide plate 5 includes a window 8, and a part of the rotating plate 21 projects from the window 8. Figure 3
From the guide plate 5 attached to the bottom plate 2 to the plate 2
It is explanatory drawing which shows the example of the situation in which 1 is overhanging. As shown in FIG. 3, the rotary shaft 22 of the plate 21 is located on the back surface of the guide plate 5. Further, the rotation speed of the plate 21 is constant. The bent portion 5a of the guide plate 5 is provided on the side where the postal matter 80 is input, and is bent to the side opposite to the space where the postal matter 80 is accumulated. The bent portion 5a prevents the input postal matter 80 from advancing toward the rotation axis 22 of the plate 21.

The plate 21 has a shape provided with one or a plurality of blades. FIG. 3 shows an example in which the plate 21 has two blades 23a and 23b. By rotating the plate 21, the blades 23a, 23b
Alternately project from the window 8. Further, the plate 21 is
The blades 23a and 23b protruding from the window 8 rotate so as to move from the side 50 side to the side 51 side. For example, in the example shown in the drawing, the plate 21 rotates so that the rotation direction when viewed from above the mail collecting device is clockwise. The blades 23 in which the inserted postal matter 80 alternately protrudes from the window 8
When contacting a and 23b, the portion protruding from the window 8 moves from the side 50 side to the side 51 side, so that the postal matter 80 is also carried in the direction of the side plate 3. The side plate 3 stops the movement of the postal matter 80 when the tip 80a of the postal matter 80 reaches the side plate 3. The plate 21 is made of a material such as rubber, plastic, silicon, or iron.
However, the material of the plate 21 is not limited to these, and may be made of other materials.

The side plate 3 is installed so as to be perpendicular to the bottom plate 2. The bottom plate 2 is inclined so that the side 50 is higher than the side 51. Therefore, as shown in FIG. 1, the side plate 3 forms an inclination angle 41 with respect to the surface on which the mail collecting device is installed. In addition, the side plate 3 is a guide rod 6
Equipped with. The guide rod 6 is passed through the holding sliding portion 7. The holding sliding portion 7 is movable along the guide rod 6. The support plate 4 is provided on the holding slide portion 7, and the distance between the support plate 4 and the plate 21 changes as the holding slide portion 7 moves along the guide rod 6. The side plate 3 is also provided with stoppers 3a and 3b that stop the movement of the holding slide portion 7. The support plate 4 faces the plate 21 and the guide plate 5. In this example, the support member is composed of the support plate 4 and the holding sliding portion 7.

The length of the holding sliding portion 7 in the guide rod direction is larger than the thickness of the support plate 4. Holding sliding part 7 is stopper 3
The support plate 4 is provided on the holding slide portion 7 so that a gap is formed between the support plate 4 and the guide plate 5 when the support plate 4 contacts the a. The width of the gap formed when the holding sliding portion 7 comes into contact with the stopper 3a is adjusted to the height at which the blades 23a and 23b of the plate 21 project most from the window 8. That is,
When the holding sliding portion 7 is in contact with the stopper 3a, when the blades 23a and 23b project most from the window 8, the blade 2
The tips of 3a and 23b contact the support plate 4.

The mail collecting device is provided with fixed pulleys 11a to 11d near the side plate 3. The fixed pulleys 11a to 11d are
It is attached to a bracket (not shown in the drawing), and this bracket is attached to the side plate 3. The side plate 3 also includes a spring mounting portion 13 that supports the plurality of springs 14 and 15. The springs 14 and 15 are not constant weight springs, but are springs whose force to restore the original length increases as the elongation increases. The springs 14 and 15 have different spring strengths. Here, the spring 15 is the spring 14
The strength of the spring is stronger than that. Each spring 14,15
The movable pulleys 12b and 12a are attached to the tips of the respective pulleys.

One end of the wire 16 is attached to the holding sliding portion 7. The other end of the wire 16 is connected to the side plate 3
It is fixed to the wire attachment portion 17 provided on the. Wire 1
6 is a fixed pulley 11a, a moving pulley 12a, a constant pulley 11b, a moving pulley 12b, a constant pulley 11c, from the wire attachment part 17 side.
It is hung on the fixed pulley 11d and attached to the holding sliding portion 7. The force of the springs 14 and 15 pulling the movable pulleys 12a and 12b causes the wire 16 to be stretched between the wire mounting portion 17 and the holding sliding portion 7.

The bottom plate 2 is tilted so that the position of the side 52 is higher than that of the side 53. Therefore, mail 8
When 0 is accumulated, the support plate 4 receives the gravity of the postal matter 80. The support plate 4 receives the gravity of the accumulated mail,
It is pushed down along the guide rod 6. At this time, since the wire 16 attached to the holding sliding portion 7 is pulled by the gravity of the mail piece, the spring 14 extends and the moving pulley 12b moves toward the guide plate 5. The support plate 4 moves to a position where the gravity of the postal matter and the support plate 4 and the force of the spring are balanced. Since the spring strength of the spring 14 is weaker than that of the spring 15, the spring 14 extends earlier than the spring 15. The back plate 3 also includes a stopper 18 that limits the moving distance of the moving pulley that is moved by being pulled by the wire 16. Back plate 3
Comprises at least a stopper 18 which limits the travel distance of the moving pulley corresponding to the spring of each spring whose strength is not maximum. The stopper 18 shown in FIG. 2 limits the moving distance of the moving pulley 12b corresponding to the spring 14 having a non-maximum strength. The weaker spring 14 is stretched by being pulled by the wire 16, and when the stretch exceeds a certain length, the force of the wire 16 trying to pull the spring 14 and the force of the spring 14 restoring the original length. Will be out of balance. The stopper 18 is provided at a position to stop the movement of the moving pulley 12b when the extension of the spring 14 reaches this length. As the stack of mail increases, the wire 16 is pulled and the spring 14 stretches. When the movable pulley 12b hits the stopper 18, the movable pulley 12b stops at that position. Then, the spring 15 stronger than the spring 14 extends while supporting the support plate 4, and the moving pulley 12 a also moves toward the guide plate 5. The spring 15 begins to extend before the moving pulley 12a hits the stopper 18.

Next, the operation will be described. When the postal matter is not accumulated, the holding sliding portion 7 is pulled by the wire 16 and comes into contact with the stopper 3a. At this time, the support plate 4
When the blades 23a and 23b of the plate 21 project most from the window 8, the tips of the blades 23a and 23b come into contact with the support plate 4 when a gap is generated between the guide plate 5 and the guide plate 5. Plate 2
Since 1 is rotating, the tips of the blades 23a and 23b appear alternately and the plate 21 intermittently contacts the support plate 4 in a state in which mail pieces are not accumulated.

The postal matter 80 is sandwiched between the belts 81 and 82 and conveyed while standing. Orbiting belt 8
The postal matter 80 conveyed by 1, 82 is put into the gap between the support plate 4 and the guide plate 5. The bent portion 5a of the guide plate 5 prevents the input postal matter 80 from advancing in the direction of the rotary shaft 22, and the guide plate 5 keeps the postal matter in the gap between the support plate 4 and the guide plate 5. Lead.

Since the bottom plate 2 is inclined so that the side 50 is higher than the side 51, the mail 80 inserted is
The plate 21 protruding from the window 8 is reached. Plate 21
Is rotating, the contacted postal matter 80 should be fed to the tip 80a.
Move until side plate 3 is reached. The height of the blades 23a and 23b protruding from the window 8 changes with rotation.
Therefore, the postal matter 80 reaching the side plate 3 is not always in contact with the plate 21, but is in contact with the blades 23a and 23b protruding from the window 8 when the height of the blades 23a and 23b is high. Do not touch when the height becomes low. Thus, the plate 21 intermittently contacts the mail piece 80.

Further, since the bottom plate 2 is inclined so that the side 52 is higher than the side 53, the postal matter 80 is inclined toward the support plate 4 side. Further, the postal matter 80 is struck by the blades 23a and 23b, so that the postal matter 80 is pressed against the support plate 4. Therefore, the mail 80 is pressed against the support plate 4,
It is supported by the support plate 4. 80 postal items transported
Are accumulated as an accumulated mail piece 90.

FIG. 4 is an explanatory view showing the back surface of the side plate 3 when mail items are accumulated. The apex 62 is arranged at a position higher than the apex 61. Therefore, as shown in FIG. 4, the bottom plate 2 forms an inclination angle 42 with respect to the horizontal plane.
Since the support plate 4 supports the accumulated mail piece 90, it receives the gravity of the accumulated mail piece 90. Due to this gravity, the holding sliding portion 7 receives a force toward the stopper 3b, and the holding sliding portion 7 and the support plate 4 move toward the stopper 3b.
Further, the wire 16 is pulled by the holding sliding portion 7, and the moving pulley moves. At this time, the spring 1 with the weaker spring strength
The moving pulley 12b attached to No. 4 starts to move first. The spring 14 is stretched when the moving pulley 12b is pulled by the wire 16.

The postal items to be subsequently conveyed are similarly accumulated. That is, the postal matter is moved by the rotating plate 21 until the tip reaches the side plate 3. Further, since the bottom plate 2 is inclined so that the side 52 is higher than the side 53, the postal matter is inclined toward the support plate 4 side. Then, when the plate 21 is hit, it is pressed against the support plate 4. In addition, by increasing the number of accumulated mail items 90,
The holding sliding portion 7 and the support plate 4 move in the direction of the stopper 3b.

FIG. 5 is an explanatory diagram showing a situation in which a new mail piece 80 is conveyed while the accumulated mail piece 90 is present. As shown in FIG. 5 (a), the accumulated postal matter 90
If a gap continues to exist between the two, the front end 80a of the newly conveyed postal matter 80 becomes the end 90 of the accumulated postal matter 90.
Hitting b, it becomes difficult to smoothly accumulate. However, each of the accumulated mail pieces 90 tilts toward the support plate 4 side and the plate 21
Since it is hit by, it accumulates without a gap as shown in FIG. Therefore, the newly transported mail 80
The tip 80a of the sheet does not hit the end 90b of the accumulated mail piece 90 and can be smoothly accumulated.

As the accumulated mail piece 90 increases and the gravity of the accumulated mail piece 90 applied to the support plate 4 increases, not only the spring 14 but also the spring 15 expands. That is, by the movement of the support plate 4, not only the moving pulley 12b but also the moving pulley 12a is pulled and moved by the wire 16. Spring 14,
Reference numeral 15 is not a constant weight spring, and if the extension increases, the force for restoring the original length also increases. Also, spring 1
When the length of 4 exceeds a certain length, the wire 16 moves to the spring 14
The force for pulling the spring 14 and the force for restoring the spring 14 to the original length cannot be balanced. However, when the extension of the spring 14 reaches this length, the movement of the moving pulley 12b pulled by the wire 16 is stopped by the stopper 18. Therefore, the balance of forces is not balanced and the support plate 4
The distance between the guide plate 5 and the guide plate 5 does not suddenly increase. After the movement of the movable pulley 12b is stopped by the stopper 18, the wire 16 moves the movable pulley 12a to pull the spring 15. When the force of pulling the springs 14 and 15 by the wire 16 increases due to the accumulated postal matter increased after the movement of the movable pulley 12b is stopped by the stopper 18, the increased force is applied only to the spring 15. Therefore, the spring 14,
15 can pull the holding sliding portion 7 via the wire 16 even if the number of accumulated mail pieces 90 increases. as a result,
Even if the number of the accumulated mail pieces 90 is increased, the support plate 4 has the accumulated mail pieces 9
Can support 0.

In the present invention, the bottom plate 2 is tilted so that the postal matter 80 thrown in is tilted toward the support plate 4 side, and the plate 21
The piled mail pieces are hit by the wings 23a and 23b of the blades and pressed against the support plate 4. Therefore, since it is not necessary to provide a belt on the bottom plate, the configuration of the paper sheet stacking device can be simplified. Further, in the present invention, the springs 1 having different strengths are used.
Even if the wire 16 is pulled by a force greater than the force that the spring 14 tries to restore the original length, the spring 15 stronger than the spring 14 works. Therefore, the accumulated mail can be supported even if the accumulated mail increases. Further, by using a plurality of springs, the amount of mail that can be collected can be increased. Further, the accumulated mail piece contacts the plate 21 when the height of the blades 23a and 23b protruding from the window 8 becomes high. Therefore, the plate 21
It is possible to shorten the contact time between the accumulated mail and the mail.

In the above example, the case where two springs are used has been shown, but the wire may be pulled by three or more springs.

In the above example, the plate 21 has the blades 23a and 23b.
The number of blades provided in the unit may be one, or 3
It may be more than one. Furthermore, the tip of the blade may be bent in an L shape. FIG. 6 shows four blades 23c-23.
An example of a plate having f and the tip of each blade being bent in an L shape is shown. Such a plate is used as a guide plate 5
It may be provided on the back surface of.
