Used in machines.

In this type of paper sheet conveying and accumulating device, generally, the impeller is forcibly rotated at a speed slower than the paper sheet feeding speed.

(Problems to be solved by the invention) However, in the above-described paper sheet conveying and accumulating device, the leading edge of the paper sheet to be fed and the blade of the impeller intersect linearly from time to time, and as a result, the paper sheet If the paper is popping out, or if the paper is thick (cards), the tip of the blade may pierce,
Thin paper sheets often break and damage the paper sheets.

In view of this, the present invention smoothly guides the paper sheet between the blades and conveys the paper sheet to the stacking point even when the tip of the paper sheet and the blade cross linearly, and the paper sheet jumps out. The present invention has been made for the purpose of providing a paper sheet conveying and accumulating device that does not cause damage.

[Constitution of device]

(Means for Solving Problems) In order to solve the problems of the above-described conventional technology, the present invention confronts a transport path for transporting paper sheets one by one and a paper sheet delivery section of this transport path. An impeller that receives and transfers the rotated and delivered paper sheets between the blades, and a member that locks the paper sheets that are received and transferred between the blades of the impeller and takes out the paper sheets from between the blades. And a stopper member, which comes into contact with the tip of the blade at the sheet feeding section of the transport path and is elastically deformed by the rotational movement of the blade, and the tip of the sheet fed from the sheet feeding section is moved to the blade. It is characterized in that a flexible guide part for guiding between is provided.

(Operation) With the above-described configuration, since the flexible guiding part is rotated by the tip of the blade of the impeller to rotate, the tip of the paper sheet sent through the conveying path is not attached to the tip of the blade when entering between the blades. The collision is avoided by the presence of the flexible guiding piece, and the leading edge of the blade and the paper sheet does not linearly collide with each other by being guided along the guiding piece between the blades.

(Embodiment) Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings.

FIG. 1 is a plan view of an embodiment of a paper sheet conveying and accumulating device according to the present invention, and FIG. 2 is a right side view of FIG.

The transport path 1 for transporting the paper sheets P one by one is provided with shafts 3 and 4 which are axially supported by the machine base 2 in an upright state, rollers 5 and 6 fixed to the shafts 3 and 4, and other not shown. The belts 7 and 8 are respectively wound around the rollers on the shaft of, and one surface of each of the belts 7 and 8 is elastically pressed. Then, it is rotated at a predetermined conveying speed by a driving mechanism (not shown), and the paper sheet P is nipped and conveyed between the belts 7 and 8 in an upright posture, and the sensors S ₁ and S ₂ detect the number of passing sheets. It has become. In this case, the upper surface of the machine base 2 guides the lower edge of the paper sheet P being conveyed.

The impeller 9 is provided so as to face the paper sheet delivery section 1A of the transport path 1, and is impeller body 11 rotatably supported by a shaft 10 that is axially supported by the machine base 2 in series. When,
The main body 11 is composed of blades 12, 12 ... Which are planted at a peripheral edge of the main body 11 at a predetermined pitch and extend outward in a spiral shape. The blades 12, 12 ... Are formed of highly elastic leaf springs or resin. There is.

A drive belt 13 is pressed against the outer peripheral edges of the blades 12, 12, ... Of the impeller 9. This drive belt 13 has a shaft 1
It is wound around rollers 16 and 17 fixed to Nos. 4 and 15, and is rotated in the direction of the arrow by driving the drive shaft 16.

The peripheral speed of the peripheral edge of the impeller 9 is set to 1/2 to 1/5 of the peripheral speed of the belts 7 and 8 of the conveyance path 1.

The locking member 18 faces the upper and lower positions of the blades 12, 12, ... of the impeller 9 in a fork shape, and the lower end of the locking member 18 is fixed to the front side surface of the machine base 2 (lower side in FIG. 1). The rear portion (left side portion in FIG. 1) of the locking member 18 constitutes the side wall 19 of the paper sheet accumulating chamber, and the left side in the drawing increases as the accumulation amount of the paper sheets P increases. Also serves as a guide for the leading edge of the paper sheet that is moved to.

In the drawing, reference numeral 20 denotes a pressing piece that is pressed and urged toward the peripheral edge of the impeller 9, and is for pressing the stacked paper sheets P against the peripheral edges of the blades 12, 12 ... With the increase in the number of accumulated sheets, a guide mechanism (not shown) resists the force of the biasing spring and moves the sheet to the left in FIG. Further, reference numeral 21 prevents the paper sheets P taken out from between the blades 12 and 12 from popping out due to rebound when locked by the locking member 18, and the length of the paper sheets in the conveying direction (see FIG. 1). Is a side wall of the stacking chamber that guides the trailing edge of the stack of paper sheets when the paper sheet is stacked vertically. The side wall 19, 21, the pressing piece 20 and the upper surface of the machine base 2 form an accumulation chamber 22.
Are formed.

In the present invention, a flexible guiding piece 23 is provided on the paper sheet feeding portion 1A of the conveying path 1.

This flexible guiding piece 23 is attached to a mounting plate 24 fixed on the machine base 2 in the vicinity of the roller 5 in the delivery section 1A of the transport path 1. The mounting plate 24 has a vertical portion 24B that rises upward from the horizontal mounting portion 24A. The left side surface of the vertical portion 24B in FIG. 1 transfers the paper sheet P to the blades 12, 12, ... It is a guide surface 25 to guide,
The base portion of the flexible guiding piece 23 is attached to the opposite surface of the vertical portion 24B.

The constitutional requirements of the flexible guide piece 23 are the strength of the waist that has sufficient resilience after being deformed by being pushed away by the rotation of the blade, and the flexibility that allows deformation by paper sheet collision,
It has durability to withstand repeated contact with the blade.

A nylon sheet, a vinyl sheet, a Teflon sheet, or the like is used as the material for the configuration that satisfies the above requirements.
When a nylon sheet is selected, two 0.016 mm thick sheets are combined. As a means for attaching the two nylon sheets to the attachment plate 24, as shown in FIG. 3, a part of the sheets 23A and 23B is fixed by thermal adhesion,
The fixed portion 23C is fixed to the mounting plate 24. By doing so, the leading ends of the sheets 23A and 23B can move independently. The reason why two sheets are used together is that, for example, when two sheets of the above-mentioned sheets 23A and 23B, that is, one nylon sheet having a thickness of 0.032 mm is used as one sheet, local deformation due to contact with the blades 12 is caused. Becomes large and durability deteriorates. Also thickness 0.016
When a single mm nylon sheet is used, it is too thin, resulting in poor waist strength and durability. Therefore, when a nylon sheet is used, the sheets 23A and 23 having the above-mentioned dimensions are used.
It is desirable to use two sheets of B together.

Next, the operation of the above embodiment will be described with reference to FIGS. 4 to 6.

4A to 4C show a case where the flexible guiding piece 23 does not directly act and the paper sheet P enters between the blades 12, 12, ... (D) shows the blade 12 in which the paper sheet P is at the paper sheet entry position due to the action of the flexible guiding piece 23.
6A shows the case of entering the left side, and FIGS. 6A to 6D show the case of entering the right side.

In the case of FIG. 4, just before the tip of the flexible guiding piece 23 is pushed away by the tip of the blade 12, the tip of the paper sheet P is positioned against the guide surface 25 (FIG. 4 (A)). Immediately after the tip of the blade 12 has passed through the tip of the flexible guiding portion 23, the tip of the paper sheet P is guided between the blades 12 and 12 while being guided by the guide surface 25 (Fig. 4 (B)-
(C)). Therefore, in this case, the leading end of the paper sheet P does not interfere with the flexible guiding piece 23, and serves only as a guide for guiding between the blades 12, 12.

In the case of FIG. 5, the tip of the paper sheet P reaches the position of the flexible guiding piece 23 along the guide surface 25 while the flexible guiding piece 23 is being pushed away by the tip of the blade 12. (FIG. 5 (A)), and in this case, the tip of the paper sheet P slides from the guide surface 25 along the surface of the flexible guiding piece 23 (FIG. 5 (B)), and is allowed to move between them. The bending guide piece 23 is a blade 1.
It goes off from the tip of No. 2 (Fig. 5 (C)), and then enters the left side of the blade 12 (Fig. 5 (D)).

In the case of FIG. 6, the tip of the paper sheet P reaches the position of the movable guide portion 23 immediately after the flexible guide portion 23 starts to be displaced by the tip of the blade 12. A)),
The movable guiding part 23 is pushed and bent by the tip of the paper sheet P (FIG. 6 (B)), and the tip of the paper sheet P is just the flexible guiding part 23.
Contact at a substantially right angle. Mafe 1 in this state
2 moves away from the flexible guiding part 23 (FIG. 6 (C)), and at the moment the tip of the blade 12 separates from the flexible guiding part 23, the paper sheet P enters the right side of the blade 12 ( FIG. 6 (D)).

In this way, regardless of the relationship in which the paper sheet P enters the blade 12, the tip of the paper sheet P linearly intersects the tip of the blade 12 due to the presence of the flexible guiding piece 23. Therefore, the blade can be smoothly guided to the left or right side of the blade and can be stored between the blades.

The paper sheet P that has entered between the blades 12 and 12 is squeezed by the locking member 18 and aligned behind the locking member 18 in the same manner as in the conventional device, and is placed between the blade 12 and the pressing piece 20. They are held in an aligned state and accumulated.

In the illustrated embodiment, the case where the paper sheet P is conveyed in the standing posture has been described, but the paper sheet P is fed in the horizontal posture and is passed through the impeller 9 as schematically shown in FIG. The same can be applied to the case of stacking in a standing posture, and two impellers 9 may be provided coaxially to support near both ends of the paper sheet P. In this case, the flexible guide piece 23 may be provided for each impeller.

[Effect of device]

As described above, according to the present invention, in the case of stacking paper sheets by means of an impeller, the tip of the blade is brought into contact with the paper sheet feeding portion of the transport path for transporting the paper sheets one by one, and the blade is rotationally moved. By providing a flexible guide part that is elastically deformed by and that guides the tip of the paper sheet sent from the paper sheet feeding section between the blades, the tip of the paper sheet fed between the blades is the tip of the blade. When the paper is fed at a timing that linearly intersects with the blade, there is always a flexible guide part at the tip of the blade, so the tip of the paper sheet does not directly hit the tip of the blade and the flexible guide is It is possible to prevent the leading edge of the paper sheet from being damaged or broken by hitting one piece, and the paper sheet can be smoothly fed between the blades without being damaged.
