DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a banknote counter, and more particularly to a banknote counter capable of preventing misalignment of banknotes.

“Conventional technology” Conventionally, as a bill counting machine that counts while bills loaded in a holder are attracted to a suction shaft and flipped one by one,
The banknote counting machine that the applicant previously applied for
No. 4979) is known. Then, in this bill counting machine, a light projector that irradiates the surface of the bill with a light beam, and a light receiver that detects the light beam reflected on the surface of the bill that is attracted to the suction shaft and linearly reads the surface pattern of the bill By having the and, it has a function of checking whether or not bills of different denominations are mixed in the bills being counted.

[Problems to be solved by the invention] By the way, in the above-mentioned conventional banknote counter, since the pattern on the banknote surface is read by one line having a predetermined height, the banknote is read when the position of the banknote shifts up and down. Becomes inaccurate, making it difficult to make a correct determination. Therefore, it is necessary to prevent the banknotes from being displaced so that the banknotes can be reliably read at a predetermined position.

The present invention has been made in view of the above circumstances, and an object thereof is to reliably prevent the position of a bill from being vertically displaced when reading a pattern on the bill surface,
An object of the present invention is to provide a bill counting machine capable of smoothly reading a pattern at a predetermined position on the surface of a bill.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a rotary cylinder that rotates about an axis and a rotary cylinder that is provided at a position radially separated from the axis in parallel with the axis. With the suction shaft for rotating while revolving around the center and for sucking and separating the bills on the bundle held by the holder one by one by the internal vacuum pressure, the bills are discriminated by optical means. In a bill counting machine configured to detect the mixing of different types of bills, a stop outside the revolving locus of the suction shaft on the rotary cylinder, where the counted bills collected by the suction shaft on the rotary cylinder are collected Below the position, the upper guide surface is
A guide rail that is set slightly lower than the lower edge position of the bill held in the holder and supports the lower edge of the counted bills is arranged.

"Operation" In the bill counting machine of the present invention, by the guide surface of the guide rail arranged below the stop position when the bills are counted,
By guiding and supporting the banknotes, the vertical displacement of the counted banknotes is prevented, and thus the uncounted banknotes among the bundled banknotes are moved along with the vertical movement of the counted banknotes. Suppress.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In these drawings, reference numeral 1 is a counting unit base plate, and a peripheral wall 2 is provided on the counting unit base plate 1 so as to surround the counting unit. A rotary cylinder 3 is rotatably provided around the shaft 4 on the counting unit base plate 1.
A plurality of (five in FIG. 1) suction shafts 5 are rotatably provided at regular intervals at positions distant from the shaft 4 in the rotary cylinder 3. The suction shaft 5 sucks and separates the bundled banknotes held by a holder 6 provided adjacent to the rotary cylinder 3 one by one, and rotates along with the rotation (revolution) of the rotary cylinder 3. It is like this. In addition, each suction shaft 5 is provided with a position regulation plate 7 that regulates the position of the bill.

In the holder 6, a vertical plate 10 is erected on one side of a mounting plate 9 that is rotatably provided around a shaft 8, and a support plate 11 is opposed to the vertical plate 10 and a support plate 11 is provided on the shaft 12. The vertical plate 10 and the support plate 11 are rotatably provided around the
A bundle of banknotes is held between and.

Further, a paper contact member 13 is provided on the free end side of the placing plate 9 described above. In this paper-contact member 13, a mounting table 14 that matches the height of the mounting plate 9 is arranged so as to face the suction shaft 5 at a predetermined position (banknote suction position) A on the rotary cylinder 3, and this mounting table A front plate 15 having an arcuate curved surface is erected on the vertical plate 14 along the rotation path of the vertical plate 10. On the back side of the front plate 15, an upper pressing leaf spring 16 for supporting the upper portion of the bill held in the holder 6 is provided in a state of being screwed to the peripheral wall 2, and the upper pressing leaf spring 16 is provided. The front end of is formed in an arc shape, is bent at a substantially right angle, and is disposed so as to face between the suction shaft 5 at the bill suction position A and the mounting table 14. further,
A lower pressing leaf spring 17 for supporting the lower portion of the bill held by the holder 6 is provided on the lower surface of the placing table 14 in a state of being supported from below by a sponge 18 and screwed. The tip of the pressing leaf spring 17 is formed in an arc shape, is bent at a substantially right angle, and is arranged so as to face between the suction shaft 5 and the mounting table 14. The pressing leaf springs 16 and 17 support the upper and lower portions of the bill at their tip portions, and when the bill is adsorbed by the suction shaft 5, the holding plate springs 16 and 17 are laterally and downwardly moved from the passage of the bill. It is supposed to be evacuated to.

Between the mounting table 14 and the rotary cylinder 3, an exhaust nozzle 19 for separating the bundled banknotes one by one is installed upward, and the rotary cylinder 3 is disposed from the position of the exhaust nozzle 19.
A predetermined position (stop position of counting bills) B along the rotation direction of the
An arc-shaped guide rail 20 is arranged between the two. The guide surface 21 of the guide rail 20 is set to be slightly lower than the height of the mounting plate 9 or the mounting table 14 described above.

Further, a separator 22 is provided near the rotary cylinder 3. The separator 22 is supported by a shaft 23 so as to be horizontally rotatable, is urged counterclockwise in FIG. 1 by a spring 24, and is rotated clockwise in FIG. 1 by a batch solenoid 25. When different types of bills are detected, they are inserted between the bills that have already been flipped and the bills that have not been flipped, so that they are separated.

Further, in FIG. 1, reference numerals 26 and 27 are a light transmitter and a light receiver for double feed detection, respectively. Both the light projector 26 and the light receiver 27 are provided toward the rotary cylinder 3 side, and the light beam emitted from the light projector 26 is irradiated from the direction intersecting the flipped banknote, The double feed is determined by detecting the amount of light transmitted through the bill with the light receiver 27.

Further, reference numeral 28 in FIG. 1 denotes a pattern discriminating mechanism. The pattern discriminating mechanism 28 has a light projector and a light receiver arranged vertically, and detects the pattern on the surface of the bill to discriminate the denomination and front / back of the bill. It is something to do.

When counting a bundle of banknotes using the banknote counter configured as described above, the bundle of banknotes is first placed on the mounting plate 9 of the holder 6 as in the conventional case, and The banknotes of 1 are brought close to the direction of the rotary cylinder 3, and the banknotes in the state of being sandwiched between the vertical plate 10 and the support plate 11 are separated and adsorbed one by one onto the suction shaft 5 of the rotary cylinder 3. In this case, since the banknotes facing the suction shaft 5 among the banknotes in the bundle are supported by the pair of upper and lower pressing leaf springs 16 and 17, there is no problem that the upper part of the banknotes falls down. , Is attracted to the suction shaft 5 in the correct posture. Next, when the bills attracted to the suction shaft 5 move together with the suction shaft 5 to release the engagement state with the both pressing plate springs 16 and 17, the next bill is the above pressing plate springs 16. It is ensured that two or more banknotes are sent at the same time because the air, which is locked to the tips of the banknotes 17 and 17, and is discharged upward through the exhaust nozzle 19, judges the bundle of banknotes. To be prevented.

The bills attracted to the suction shaft 5 are curved at the tip of the support plate 11 by rotating the suction shaft 5 clockwise while revolving the rotary cylinder 3 in the counterclockwise direction in FIG. It is sent to the stop position B on the guide rail 20 at the time of counting. In this case, the surface pattern of the banknote is first detected by the pattern determining mechanism 28 in the vicinity of the suction position A between the suction position A and the stop position B, and based on this detection pattern,
Whether or not the bills are different types is determined, the suction shaft 5 is released from the suction on the bill, and the position regulating plates 7 of the front and rear suction shafts 5 are released.
Projector 2 for double feed detection at position C sandwiched between
6 and the light receiver 27 detect whether or not the double feed is performed. Here, when the pattern discriminating mechanism 28 detects the surface pattern of the banknote, since both the pressing leaf springs 16 and 17 support the edge portion of the banknote, the upper part of the banknote is prevented from falling and detected. The pattern is stable and does not adversely affect the discrimination. If the pattern discrimination mechanism 28 discriminates a different type of sheet, the batch solenoid 25 causes the separator 22 to move the elasticity of the spring 24 around the shaft 23. By rotating in a clockwise direction in FIG. 1 against the force and interrupting the bills that have already been flipped over and the bills that have not been flipped over, the two are separated, so that different types of bills can be easily eliminated. .

In this way, the bills held on the holder 6 are sequentially adsorbed to the respective suction shafts 5 of the rotating (revolving) rotating cylinder 3, and the respective suction shafts 5 are rotated to perform a counting process. And is sent to the stop position B. In this case, from the suction position A to the stop position B, the lower edge of the bill is
Guide rail 20 slightly lower than the mounting plate 9 and the mounting table 14.
It smoothly moves to the guide surface 21 and is securely supported and guided by the guide surface 21. Particularly, at the stop position B,
Since the lower edge of the banknote is stationary while being held on the guide surface 21 of the guide rail 20, the uncounted banknotes do not move vertically, and the number of uncounted banknotes decreases. However, the counting process is performed smoothly and does not affect the pattern detection. In this respect, in the case of the conventional device in which the guide rail 20 is not provided, the number of bills at the stop position B at the time of counting increases as the flipping operation progresses, and the suction shaft 5 that is flipped is When passing, the tip of the bill is vibrated. And the suction shaft 5
Since the position regulation 7 provided in the section gives an irregular vibration, the tip of the banknote bundle becomes downward. As a result, when the number of uncounted banknotes is reduced, the leading edge of the uncounted banknotes is lowered at the suction position (pattern detection position) A along with the downward movement of the counted banknotes. While the detection may be adversely affected, the present invention has solved the above-mentioned inconvenience.

[Advantages of the Invention] As described above, the present invention is located on the outside of the revolving locus of the suction shaft of the rotary cylinder provided with the suction shaft that sucks and separates the bundled banknotes one by one. Below the stop position where the counted bills collected by the suction shaft of are collected, the guide surface which is the upper surface thereof is set slightly lower than the lower edge position of the bill held by the holder, Since the guide rail for supporting the lower edge of the bill is arranged, by guiding and supporting the bill by the guide surface of this guide rail, the vertical displacement of the counted bills is prevented, thereby, It is possible to prevent the uncounted banknotes of the bundled banknotes from moving along with the vertical movement of the counted banknotes, and it is possible to reliably read the surface pattern of the banknotes at a predetermined position. Therefore, there is an excellent effect that the bill counting process can be performed smoothly and the reliability can be improved.
