Abstract

PURPOSE:To secure certain capability of detecting both vertical and lateral displacements of a paper sheet and miniaturize the handling unit rotated thereto, by arranging two pairs of detector consisting of two sheets of lever making differential rotation in parallel with each other, on a paper sheets parting board. CONSTITUTION:A sensor 37 for detecting the remainder on separators 23a, 23b is so arranged as the tips of levers 64, 65 touch the separator 23 on input paper money 51 placed thereon. The separator 23 is provided with a hole at one position into while the lever 65 plunges when there is no input paper money 51 and if tips of levers 64, 65 stay in the same level, partial areas of levers 64, 65 shield the optical axis 100 of an optical sensor 66 and the shield on the optical axis is cleared when the lever 65 plunges into the hole of the separator 23. In addition, the lever 65 is very slightly longer than the lever 64, and this fact contributes to maintain 1a constant phase difference of the lever 65 in relation to the lever 64 even when the vertical position of the separator 23 is changed, so that presence/absence of input paper money 51 can be discriminated in a steady state. Thus, thickness of the separator 23 can be only several mm, duly realizing compact dimensions for the whole unit.

The structure is such that the sheets are fed one by one to a conveying section (not shown in the drawings) located further ahead.

Next, with reference to Fig. 1 and Figs. 3 to 8,
Regarding the paper stacking and retrieval operations of this device.

I will explain. First, when accumulating deposit paper, as shown in Fig. 1, the pick-up roller 42 is retracted to 'Y' upwards, and at the same time, the shutter 10 is set to the lowered position to block the progress of the deposit paper. .At this time, the third
As shown in the figure, by moving the drive bin 27 to an appropriate position near the upper center of the carrier 24,
The separators 23a and '23b are placed on the press plate 22 and pressed against the press spring 21.

The pressure and spring constant of the spring 21, which is biased and raised to the stack roller 6.7, are set appropriately.

By doing so, it is transported by the transport belt 1.2f.

The tip of the deposited deposit paper stops when it hits the shutter 10, and is sequentially accumulated on the separators 23a and 23b. When storing the accumulated deposit papers 51 in this manner, the pusher 30 is lowered to lower the deposit papers 51 and the push plate 22, and at the same time the drive bin 27 is moved.

Raise the carrier 24Y. As a result, as shown in FIG.

The operation is as shown in Figure 7, using the pickup ruler.

42 is lowered and the deposit paper 51 is stacked on the stack roller 6.

Push it down to a position far enough away from 7. Upper moth.

The ID plate 31 is simultaneously lowered below the stack roller 6.7 by a link mechanism not shown, so that the deposit paper 51 does not touch the stack roller 6.7.

Then, the shutter 10 shown in FIG.
is the feed roller 43. 211 is raised to a position where it is not prevented from being sent between the gate rulers 44. The drive bin 27 is located above the long center of the carrier 24, so that the carrier 24 can rise freely upward, and the carrier 24 is attached to a Funston spring 48 (the length of the spring can be changed), although it was not mentioned above. It is supported by a spring whose load remains constant even when the pressure is on, and its own weight is canceled out, so that the pressure of the pressing spring 21 is picked up.
La 42 can be added as is. I was twitchy after this.

Rotate the up ruler 42 and feed ruler 43,
Take out the deposit paper 51 one by one and remove the remaining paper 51.
7m, 37bK, it is detected that the deposit paper 51 is exhausted and the take-out operation is completed.

To take out the storage paper 52, as in the case of taking out the deposit paper 51, after lowering the pickup roller 42 and raising the shutter, the drive bin 27 is raised as shown in FIG. Raise the carrier 24 until it touches the guide plate 51, and then lift it.

After big up roller 42. The feed roller 43 is rotated to take out the stored paper sheet 52, and the operation continues until the optical sensor 35 detects that the stored sheet sheet 52 is exhausted.

During the above operation, the third
The details will be explained using FIGS. FIG. 9 is a side view of the residual sensor 37, and FIG. 10 is a front view. Support shaft 3
6, via bearings 62a, 62b, 65,
The levers 64 and 65 are mounted parallel to each other so as to be rotatable, and the tips of the levers 64 and 65 are arranged so as to touch the top of the separator 23 or the deposit paper 511C on the separator 23, and one hole is provided in the separator 23. If there is no deposit paper 51, the lever 65 falls into this hole.The lever 64 has a light emitting element 66A and a light receiving element 6.
When the optical sensor '66 with 6B and 6B are fixed together and the tips of the levers 64 and 65 are on the same plane,
Part of 5 is the optical sensor.

The optical axis 100 of the separator 23 is freely spaced, and when the lever 65 falls into the hole of the separator 23, this optical axis is released.

It is configured. Lever 65 is lower than lever 64.

The object to be detected, that is, the separator 2, is very long.
Even if the vertical position of the deposit paper 51 changes, the phase difference with respect to the lever 64 when the lever 65 falls into the case separator is kept almost constant, so that the presence or absence of the deposit paper 51 can be stably detected. are doing. In this embodiment, the lever 64
．． Even if the lengths of the separators 65 were set to 35 mm and 56 H, the thickness of the separator 23 was 21111 mm, and the positional change was about 1011 mm, the phase difference could always be kept at about 4.5 degrees. The residual sensor 37 configured in this way is
As shown in FIG. 1, a pair of deposit paper sheets 51 are arranged symmetrically, so that even if the deposit paper sheets 51 are brought in unevenly, one of them can always be detected.

According to Honji Mar, even if the separator 23 is lifted by the amount of bulge caused by the distribution rate and number of paper sheets 52 stored under the separator 23, and its vertical position changes or tilts, the L It is possible to reliably detect the presence or absence of the deposit paper 51 accumulated on the separator 23 as distinguished from the storage paper 52, and the thickness of the separator 23 can be made several Im.

〔Effect of the invention〕

According to the present invention, the accumulated paper sheets are sorted.

A paper sheet detector that has a partition plate and consists of two levers that differentially rotate in parallel on the partition plate.

Since two pairs of structures are arranged, the partition plate is only slightly thick.

However, the paper sheets on the partition plate, which are the objects to be detected, can be moved to one side regardless of vertical positional fluctuations.

Since it can reliably detect even when paper sheets are accumulated, it can distinguish and reliably take out paper sheets despite its compact configuration, especially for paper handling equipment such as banks.

This has a useful effect on the return process in the case of cancellation of a transaction.
