Description

[Detailed Description of the Invention] The present invention relates to a paper sheet feeding device for a paper sheet counting machine that feeds out paper products such as banknotes one by one while counting them one by one.

FIG. 1 shows the structure of this type of device, which includes a storage box 2 that stores paper sheets 1, a drawer mechanism 3 that pulls out paper sheets 1 from the storage box 2, and a drawer mechanism 3 that pulls out paper sheets 1 from the storage box 2. A blade 5a of a vehicle 5 that collects paper sheets 1.

A clamping plate 6 is provided in the storage box 2 in a state where it is always pulled toward the drawing mechanism 3 by a spring 7.

In addition, the pull-out mechanism 3 is provided with a suction member 9 having a through hole 8 connected to a vacuum pump (not shown) between the sheet 1 and the group of feed rollers 4. The paper sheets 1 are attracted one by one by the fan-shaped movement in the direction of the arrow 9 and the vacuum action, and are fed to the group of feed rollers 4.

The group of feed rollers 4 includes a pair of upper and lower rollers 4a.
, 4b are provided, and guide rails 10 for guiding the paper sheets 1 are provided.

When sending out the paper sheets 1, the paper sheets 1 stored in the storage box 2 are pulled out one by one by the drawer mechanism 3, and inserted between the blades 5a of the stacking wheel 50 by a group of rollers 4.
The saucer 11 is rotated as shown by the arrow in FIG.
At the same time, the number of paper sheets 1 was counted while being sent.

By the way, among the paper sheets 1 stored in the storage box 2, there are paper sheets 1 that are considerably damaged and have curls, etc., and such paper sheets 1 When the material travels through the passage with a group of feed rollers rotating 40 times and is delivered to the collection vehicle 5, there is a risk that the product may not be delivered to the collection vehicle 5 reliably due to the centrifugal force of the rollers, such as jumping over the collection vehicle 5 or being caught in the rollers. was there.

In order to solve these problems, it is thought to be effective to warp the paper sheet 1 between the roller groups 40 to give it apparent rigidity, and the applicant has proposed the method shown in FIG. There are two upper rollers 4a spaced apart on both sides of the paper sheet 1 in the feeding direction.
, 4a and lower rollers 4b and 4b having grooves 4c into which the outer peripheries of the upper rollers 4a and 4a are fitted are provided to sandwich the paper sheet 1 on both sides and curl it to improve its appearance. We proposed a method to provide stiffness.

However, in this method, the cut in the paper sheet 1 is between the left and right rollers, and the convex upper roller 4a,
Since two sets are provided so that the concave lower rollers 4b fit together, the paper sheet 1 is moved between the two sets of upper and lower rollers 4a,
When the 4b position is reached, if the fitting force of the uneven roller is strong, the bending force of the arrow 41 and the tension of the arrow 41 to ~ will work, as shown in Fig. Department (
There is a possibility that tensile force will be applied to the part (between the two sets of rollers) and it will be separated from the cut.On the other hand, if the fitting force of the uneven roller is weak, the part between the two sets of rollers will be separated when folded. 4 As shown in Figure 4, the center part of the paper sheet 1 bulges upward in an arc as shown by the arrow 19 due to the bending force of the arrow 19, and the paper sheet 1 is placed between the blades 5a of the collection wheel 5. There was a possibility that the roller could not be fed and could jump over the edge, causing trouble.There were also issues that required improvement, such as the need to accurately match the mating force of the rollers.

The present invention was devised in order to eliminate the above-mentioned drawbacks, and is a paper sheet counting machine that provides apparent rigidity to both sides of the paper sheets so that they can be reliably transferred from a group of feed rollers to a stacking vehicle. The purpose of the present invention is to provide a filter paper sheet feeding device for use in the United States.

An embodiment of the present invention will be described below based on the drawings.

In the present invention, the paper sheets 1 stored in the storage box 2 in FIG. In a paper sheet counting machine configured to collect paper sheets in a receiving tray 11, a pair of upper rollers 4a, 4a are installed at a position immediately in front of the stacking wheel 5 and are spaced apart from each other in the transverse direction with respect to the transport direction of the paper sheets 1. and the upper roller 4 of these sets
a.

A set of lower rollers 4b for feeding the paper sheets 1 vertically and diagonally between them and the stacking vehicle 5.
, 4b are provided to constitute a part of the feed roller group 4.

That is, among these two sets, the rollers of one set, for example, the lower rollers 4b, 4b in FIG. 3, are slightly shifted to the outside of the rollers of the other set, for example, the upper rollers 4a4a in FIG. One set of rollers, for example the lower rollers 4b4b in FIG.
a small diameter portion that holds the paper sheet 1 vertically between the outer peripheral portion of a;
The other set of rollers 4a is located outside this small diameter portion.

It has a large diameter part which sandwiches the paper sheet 1 obliquely between the outside near the outer periphery of 4a, and this large diameter part is constituted by a flange 4b' having a tapered inner surface.

With this configuration, when the paper sheet 1 is not sandwiched between the upper and lower rollers 4a and 4b in front of the stacking vehicle 5, the paper sheet 1 is placed on the inner surface of the 7 langes 4b' of the lower roller 4b. The rollers 4a are in contact with each other, but when the paper sheet 1 is sent between the upper and lower rollers 4a and 4b by another roller, the paper sheet 1 is sandwiched between the upper and lower rollers 4a and 4b. Paper industry 1 is upper roller-4
The contact portion with the outer peripheral edge of the flange 4b' and the contact portion with the outer peripheral edge of the flange 4b' are bent as shown by arrows C and C in FIG. A slight tension is applied as shown by , and the sagging is corrected, resulting in the shape shown in FIG. 4C.

In addition, when folding the paper products 1 in this way, the fourth
The tension indicated by the arrows N and R in Figure C is generated by the contact between the paper sheet 1 and the outer periphery of the left and right upper rollers 4a.
This is suppressed by supplying the paper sheet 1 with both sides free along the inner surface of b', so it can be pressed smaller than, for example, the state shown in FIG. 4a. .

In addition, it is easy to send the tensioned central part of the paper sheet 1 that has been bent and stiffened to the vane 5a of the stacking vehicle 50, and the paper sheet 1 as a whole does not curve. This eliminates the risk of the inconvenience of the feed rollers jumping over the accumulating car or getting caught up in the rollers when being transferred from the feeder to the accumulating car, and not being reliably delivered to the accumulating car.

Moreover, since it has a simple structure in which the upper and lower rollers 4a and 4b are slightly shifted, the manufacturing cost does not increase.
