Abstract

PURPOSE:To improve the paper separating function as well as the accuracy in counting by taking in some sheets of paper by means of a draw-out roller and a take-in roller which have frictional and non-frictional surfaces respectively, sending them into a separating roller, and stopping the rotation of said separating roller as the paper enters said separating roller. CONSTITUTION:As a draw-out roller 3 rotates in the (b) direction, a take-in roller 7 which is frictionally brought in contact with the draw-out roller 3 rotates in the (c) direction. And, a separating roller 4 which is interlocked by means of gears 8, 9, rotates in the (d) direction. Thereby, some sheets of paper which are kicked out, are sent through each roller 2, 3, 7, and their ends are brought in contact with the separating roller 4. Thus, when some sheets of paper 1 enter the separating roller 4, a one-way clutch, not indicated in figure, operates and the rotation of both the separating roller 4 and the take-in roller 7, which is interlocked with the roller 4 through gears 8, 9, are stopped, separating the sheets of paper which are sent in piles. Thus, the separation of sheets of paper can be securely carried out improving the reliability.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter sheet feeding device in a sheet counting machine.

Conventionally, in a paper sheet counting machine that performs processing such as discrimination and counting while dispensing sheets one by one from below the dispensing section that accommodates the stacked stacks of paper sheets, the lower part of the dispensing side of the stacked paper stacks is before the separating section. Then, instead of being tilted uniformly, every few sheets become step-like, the upper side comes out forward, and the sheets are fed out in a chain, or two sheets are fed out at the same time, resulting in separation. There was a defect that made it defective.

The present invention solves this drawback, and provides a high-performance counting machine that can reliably separate and feed sheets one by one and that does not cause errors.

Next, we will explain the embodiment shown in the drawings. 1. FIG. ) A kick-out roller (2) that can come into contact with the lowest sheet of paper (1) placed on the loading plate (a) is mounted on a shaft below the loading plate (a). A feeding roller (3) that can come into contact with the lower surface of (1) is rotatably mounted on a shaft so as to be driven by a motor, and the outer peripheral surface of the feeding roller (3) has a friction surface (3a) made of uneven rubber. A smooth, non-friction surface (consisting of three ridges).

Paper sheets (1
) Both large-diameter separation rollers (
4) Fit and fix (4) to the shaft (5), and attach both separation rollers (4) (One end side of the holding arm (6) between 41 is loosely fitted to the shaft (5), and the holding arm (6) On the other end side, both small-diameter take-in rollers (7) that can approach the feeding section (4) side in front of the separation roller (4) and contact the upper side of the feeding roller (3) are coaxially rotated. A gear (9) that is freely mounted on the shaft and is integrally formed on the side of both intake rollers (7) and a gear (10) that is integrally formed on the side of both separation rollers (4) are meshed with each other. Configure.

Further, the shaft (5) is mounted on the brackets (11) αυ on both sides, and the separation roller (4) is located between the shaft (5) and the bracket α1) in the same manner as the feeding roller (3). A one-sided clutch (1o) is interposed to allow rotation in one direction but stop in the opposite direction.

Therefore, the kicking roller (2) and the feeding roller
(3) The take-in roller (7) rotates as shown by the ti arrow (control) and comes into frictional contact with the feed-out roller (3).
) rotates as shown by the arrow (c), the gear (9)
Due to the engagement of r8), the separating roller (4) rotates in the same direction as the feeding roller (3) as shown by the arrow (b).

When a sheet of paper is fed out, the lowest sheet of paper (1) is kicked out by the kicker roller (2), and the friction surface (3a) of the feeding roller (3) comes into contact with the sheet to feed it. When the paper sheet (1) reaches the separating roller (4), the taking roller j (7) rotates and the separating roller (4) rotates. (7) will promote the uptake, and the tip of the paper sheet (1) will be separated by the separation row, y - (4).
When the separation roller (4) comes into contact with the paper sheets (11) to be fed out, the rotation of the separation roller (4) is stopped, and at the same time the separation roller (4) is moved upward along with the intake port 3-r (7) which stops its rotation. This means that the paper sheet (1) to be fed out can be separated from the paper sheet above.

Additionally, when a larger number of sheets than normal try to rush into the separation roller (4), the holding arm (6) rotates upward and the take-in roller (7) rotates in a double line, causing separation. The roller (4) rotates slightly in the direction of the arrow (b) to improve the separation function.

When the flow of paper leaves is interrupted, the take-up roller (7) rotates again to promote the take-up, and the paper sheets can be continuously fed out.

In this way, in a paper sheet counting machine that performs processing such as discriminating and counting while feeding out sheets one by one from below a feeding section that accommodates piled up groups of paper sheets, the present inventor has developed a paper sheet counting machine that performs processes such as discrimination and counting while feeding out sheets one by one from below a feeding section that accommodates piled up groups of paper sheets. A feed-out roller that can contact the lower surface of the lowermost paper sheet and has a friction surface and a non-friction surface on the curved surface is mounted on a shaft so as to be driven by a motor, and a take-in roller is mounted forward on the feed-out side of the feed roller. A separation roller is provided behind the separation roller so as to be able to contact with each other, and a gap is provided behind it so that only one paper sheet can pass through, and the carcass separation roller and the intake roller are interlocked with gears, Paper I
Since the system is equipped with a one-sided clutch that prevents the separation roller from rotating in the paper sheet feeding direction when a type I enters the separation roller, separation of the paper sheet feeding is performed by the operation of the take-in roller and the separation roller. To provide a high-performance counting machine that can reliably perform the above-mentioned operations without causing any errors due to the rotation of the feeding roller and the rotation and stopping of the separation roller, and can perform good feeding without causing the above-mentioned drawbacks as in the past. It has the feature of being able to
