Abstract

PROBLEM TO BE SOLVED: To discharge the paper chips of paper sheets outside even in the case where the paper chips adheres to a shaft and intrudes into a bearing hole by forming a paper chip eliminating groove in a turning bearing hole of a lever for detecting passing of paper sheets. SOLUTION: A bill M is carried in a carrying route 4, and a tip M1 of the bill M abuts on a tip 91 of a detecting lever 9. The whole of the lever 9 is turned around a fitting shaft 10, and a sensor 14 is operated by the lever 9, and the bill M abuts on the lever tip 91 , and while passes through. The lever confirms the passing of the bill M, and thereafter, the lever 9 is reset to the original position, in which the lever 9 abuts on a stopper 16. When this process is repeated, fine powder chips generated from the bill M is scattered, and adhered to the fitting shaft 10, and intrudes into the bearing hole 11. The intruded paper chips are stayed in an escape groove of the bearing hole, without staying in the inner surface of the bearing hole. The paper chips inside of the escape groove 12 is discharged outside for elimination in a downward slope of a taper of the escape groove 12 by repeat of the turning operation of the lever 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bearing mechanism of a detection lever in a paper sheet conveying path, which is an apparatus for automatically processing bills and other paper sheets, that is, an automatic clearing machine, an automatic vending machine, etc. At the time of operation of the detection lever that confirms whether or not the paper sheets used while being stored in the storage box have passed to the storage side, the paper dust of the paper sheets adheres and the rotation is disturbed. The purpose is to eliminate the cause of.

[0002]

2. Description of the Related Art Conventionally, this type of automatic money changer, automatic clearing machine,
In a vending machine or the like, a lever having a bearing hole is attached to the mounting shaft so that the lever can be rotated in order to detect and pass the paper sheet in the conveying path of the paper sheet from the identification machine. The lever causes the tip of the lever to project into the conveying path, and when the conveyed sheet comes into contact with the sheet, the lever is rotated by the pressing force of the sheet so that the tip is retracted from the path and passed.

[0003]

However, in the above-mentioned lever, the bearing hole is rotatably fitted and connected to the mounting shaft, but since there is no escape portion in the bearing hole, the paper sheets are As the paper was repeatedly hitting and passing through the lever, the paper dust was scattered and adhered to the shaft, causing the paper powder to enter these bearing holes and hinder the rotation of the lever. Also,
As a countermeasure against the paper dust clogging, it is conceivable to form a large bearing hole for the lever in advance with respect to the shaft so that the lever can be rotated even when the paper dust enters. Although it is a plan to infiltrate the paper dust, it is not preferable because the bearing hole with respect to the shaft lacks in accuracy and leads to a decrease in accuracy of the entire apparatus.

[0004]

Therefore, according to the present invention, even if paper dust of paper sheets adheres to the shaft and enters the bearing hole,
While the lever is repeatedly rotated, the lever can be discharged and removed to the outside so that the lever can be rotated. A first aspect of the present invention is a bearing mechanism for a detection lever in a paper sheet conveyance path, in which paper dust is removed in a rotation bearing hole of a lever for detecting passage of the paper sheet in a conveyance path through which the paper sheet passes. A relief groove is formed. A second aspect of the present invention is that, in the bearing mechanism of the detection lever in the paper sheet transporting path according to the first aspect of the invention, the clearance for removing paper dust in the bearing hole of the lever is formed in a spiral shape. According to a third aspect of the present invention, in the bearing mechanism of the detection lever in the paper sheet transporting path according to the first aspect of the invention, the escape groove for removing paper dust in the bearing hole of the lever is tapered from the central portion toward both ends. Par
(= Inclined). According to a fourth aspect of the present invention, in the bearing mechanism of the detection lever in the paper sheet conveying path according to the first aspect of the invention, the clearance for removing paper dust in the bearing hole of the lever extends from one end to the other end. It is formed in a par.

[0005]

[Operation] The operation based on the above means is as follows.
That is, the paper sheet being conveyed on the conveying path is detected by the detection lever.
When the lever hits, the tip of the lever rotated and pushed down operates as a sensor, and the paper sheet passes while contacting the tip of the lever. While this process is repeated, fine paper powder generated from the paper sheets due to friction or the like scatters and adheres to the mounting shaft and also enters the bearing hole. The paper dust that has entered is collected in the escape groove of the bearing hole, but does not adhere to the bearing hole surface. Further, the paper dust in the taper-shaped escape groove is discharged and removed to the outside along the taper by repeating the rotation operation of the lever.

[0007]

[Specific Example of Process] A specific example of the process based on the above-mentioned implementation is as follows. First, among the paper sheets, banknotes M are sent by the sheet feeding belt 5 and the sheet feeding roller 6 of the identifying device 2 in FIG. 1, and the banknotes M that have passed therethrough are conveyed by the conveying belt 7 and the conveying roller. It continues to convey the conveyance path 4 by -8 in a position before the bill housing box 3, when the leading end M ₁ of the bill M hits the tip 9 ₁ of the detection lever -9 (Figure 2), the lever - downward At the same time when the lever is pressed, the entire lever rotates about the mounting shaft 10, and the detection lever 9 causes the sensor 14 to rotate.
Activated (Figure 3), a bill M is lever - to pass while in contact with the tip 9 _1. The detection lever 9 that has confirmed the passage of the bill M returns to the original position where it hits the stopper 16 (FIG. 4).
Then, while repeating this step, fine paper powder generated from the bill M is scattered and adhered to the mounting shaft 10 and also penetrates into the bearing hole 11. The paper dust that has entered does not collect on the inner surface of the bearing hole but collects on the escape groove 12 of the bearing hole. Further, the paper dust in the escape groove 12 is discharged and removed to the outside when the taper of the escape groove 12 descends toward the end surface by repeating the rotation operation of the detection lever 9.

EFFECTS OF THE INVENTION The present invention has the above-described structure, and therefore, a detection lever for contacting a large amount of paper sheets conveyed along a conveyance path, such as a paper sheet identification machine or a banknote storage box. -In a mechanism for bearing, even if fine paper dust generated from a large amount of paper sheets that pass through in contact with the lever enters the bearing hole of the lever supported by the shaft, it collects in the escape groove. Since it does not collect on the inner surface of the hole, it does not interfere with the rotation of the lever. Also, the relief groove of the bearing hole is formed in a spiral shape in the axial direction, or a taper is formed from the center of the bearing hole toward both ends.
It is a taper or a taper from one end of the bearing hole to the other end, both of which are formed in an inclined shape. Therefore, the paper dust that has entered the escape groove has the effect of promoting the discharge exclusion to the outside of the bearing hole when the taper is lowered by the turning operation of the lever. As described above, according to the present invention, even if the bearing hole of the lever is not formed so large as to rattling with respect to the mounting shaft, the paper dust of the paper sheet enters the bearing hole to rotate the lever. Obstacles that hinder the
It is useful as a bearing mechanism for the detection lever in the transport path of this type of sheet identifying machine.
