Description

A sheet medium separation device

technical field

The utility model relates to a sheet medium processing technology, in particular to a sheet medium separating device which is used in financial self-service terminals to reliably separate stacked sheet media one by one.

Background technique

At present, self-service teller machine (ATM) equipment at home and abroad has been very popular. As the core of ATM teller machine, the banknote processing core has always been the research and development focus of major manufacturers at home and abroad. When the banknote processing movement serves the outside world, the interaction with general customers mainly occurs at the banknote depositing and withdrawing ports of the movement, so the design of the depositing and withdrawing must be robust to adapt to the usage habits of different customers . For the stacked deposit movement, the function of the banknote opening is mainly to separate the stack of media placed by the customer one by one, and transmit them to the inside of the movement, so as to realize the identification of the media and subsequent transactions. In this process, due to the randomness of the customer’s banknote release, the media stack often deviates from the design in the process of separating one by one. For example, the media is inserted in consecutive sheets or double sheets, resulting in an increase in the rejection rate of the movement. . Therefore, how to ensure the reliable separation of the movement banknotes from the medium is one of the research and development priorities of the R&D centers of various manufacturers at present, even when customers randomly deposit banknotes.

Generally speaking, after the stack of media is put into the banknote opening of the movement, the movement will separate them one by one through the medium separation component. However, due to the randomness of the customer’s banknote depositing operation, the stacking of the media stack will present five states (full alignment, positive triangle at the front, inverted triangle at the front, "ㄑ" shape at the front, misalignment at the front), as shown in Figure 1 It shows that under different conditions, the separation effect of the medium separation component on the medium stack is different. Specifically, when the media stack is in the state of an inverted triangle at the front end, a "ㄑ" shape at the front end, and misalignment at the front end, the media separation component has a poor effect on separating them one by one, which is likely to cause failures such as continuous sheeting and double sheeting.

For the movements used in China, the media stack is mainly embodied as a stack of banknotes. Since domestic users are accustomed to placing banknotes horizontally (that is, the direction of movement of banknotes in the movement is along the short side of the banknote), so for the above problems, the domestic movement places the banknotes vertically (the medium separation mechanism is located in the banknote pile) bottom), use the gravity of banknotes to automatically align to the lower separation door gap during the separation process, so as to achieve the purpose of sorting the shape of the front end of the banknote pile before banknote separation.

For the movement used abroad, the medium stack contains banknotes, checks and other valuable documents. Foreign customers are used to placing banknotes vertically (that is, the direction of movement of the banknotes in the movement is along the long side of the banknote). Generally, the design of placing the banknote opening close to the horizontal direction is adopted. Under this design, some mechanisms must be introduced in the banknote slot to correct the "bad" state of the media stack (such as: the front end is inverted triangle, the front end is in the shape of "ㄑ", the front end is not aligned, etc.).

For vertical banknotes, there are two commonly used solutions at present: one is to shape the front end of the media stack by external force before the media stack enters the separation door gap, so that the front end of the media stack becomes fully aligned for easy banknote separation shape or triangle shape. As shown in Figure 2 below, a baffle 013 is set in front of the separation door gap as a reference alignment wall. Before banknotes are separated, the front end of the media stack is pressed against the baffle by external force, so that the front end of the media stack is aligned. However, this method is not reliable in actual implementation because it needs the assistance of external force.

The above scheme adopts the idea of setting up a mechanism to correct the shape of the front end of the media stack before the separation door gap. For the media that has entered the separation door gap, if it has entered in an inverted triangle state, the result of double-stretching and separation will still occur. In order to completely solve the problem of multiple banknotes and continuous banknotes caused by different shapes of the front ends of banknotes, how to improve the reliable handling ability of banknote processing cores for the above situations has always been a technical problem that technicians in the industry need to study.

Referring to FIG. 6 and FIG. 7 , the separation gear train assembly in the media separation mechanism 1 includes a separation wheel 11 , a damping wheel 13 , a separation wheel shaft 111 , a damping wheel bearing 131 , and an isolation washer 14 . Specifically, 2 separation wheels 11, 2 damping wheels 13, and 3 acceleration pulleys 31 are sequentially coaxially and separately symmetrically installed on the separation wheel shaft 111, wherein: the separation wheel 11 is fixedly connected with the separation wheel shaft 111 to realize the same speed rotation The damping wheel 13 is installed on the separation wheel shaft 111 through a damping wheel bearing 131, and when the separation wheel shaft 111 rotates at a high speed, the damping wheel 13 rotates at a slow speed in the opposite direction; each acceleration pulley 31 passes through two acceleration pulley bearings 311 respectively Installed on the separation wheel shaft 111, when the separation wheel shaft 111 rotates at a high speed, the acceleration pulley 31 can rotate in the same direction at a higher speed. In order to ensure that the separation wheel 11, the damping wheel 13, and the acceleration pulley 31 rotate simultaneously on the separation wheel shaft 111 at different speeds, the inner hub of the separation wheel 11 has a boss in contact with the inner ring of the damping wheel bearing 131, thereby ensuring that the separation wheel 11 is in contact with the inner ring of the damping wheel bearing 131.

Therefore, under the effect of the reverse wheel one-way bearing 122, the reverse wheel 12 can only rotate in one direction.

Referring specifically to Fig. 3 and Fig. 9, the power system of the sheet medium separation device will be further described. Firstly, the stop wheel mechanism 5 and the first reverse swing link mechanism 61 linked with the separation wheel 11 are controlled, specifically including the stop wheel swing link 611. , stop wheel fork cam 612, stop wheel fork one-way bearing 613, wherein, one end of stop wheel fork 611 is installed on the end of stop wheel axle 52 by stop wheel fork one-way bearing 613, and the other end and stop wheel The outer circle of the swing lever cam 612 is in contact with each other, and the inner hole of the stop wheel swing lever cam 612 is fixedly connected with the separation wheel shaft 111 . When the separation wheel shaft 111 rotates, the stop wheel swing bar 611 swings back and forth around the stop wheel shaft 52 along with the rotation of the stop wheel swing bar cam 612. Due to the existence of the stop wheel swing bar one-way bearing 613, the stop wheel 51 forms a low-speed reverse to turn. In addition, the working principle of the second reverse swing lever mechanism 62 is similar to that of the first reverse swing lever mechanism 61. Specifically, it includes a reverse wheel swing lever 621, a reverse wheel swing lever cam 622, a reverse wheel swing lever one-way Bearing 623, wherein, one end of the reverse wheel fork 621 is installed on the end of the reverse wheel shaft 121 through the one-way bearing 623 of the reverse wheel fork 623, and the other end is in contact with the outer circle of the reverse wheel fork cam 622.

Under the action of the stop wheel tension spring 55, the stop wheel 51 is elastically pressed against the damper wheel 11. The inner ring of the stop wheel one-way bearing 53 links to each other with the shaft end of the stop wheel 51, and the outer ring is installed on the stop wheel one-way bearing mounting seat 54, and the stop wheel one-way bearing mounting seat 54 is connected with the side plate by screws, so in the stop Under the effect of moving wheel one-way bearing 53, stop wheel 51 can only unidirectionally rotate.

As shown in Figures 10 to 12 below, the main difference between the sheet medium separation device provided by this embodiment and the traditional technology in medium separation is further described. In the traditional solution, as shown in Figure 10, the separation wheel and the reverse The wheel occlusion forms a separation door gap. During the normal separation process, for the medium 1 located at the bottom, the separation wheel below the medium 1 provides power for banknote separation (F _separation ), and the medium 2 above it produces frictional resistance (F _f ), the reverse wheel produces resistance to it (F _reverse ), the combined action of these three forces is F _separation > F _reverse + F _f , so that medium 1 passes through the separation gap; for medium 2, the above The reverse wheel provides resistance (F _reverse ), and the medium 1 below generates frictional force (F _f ) on it. Under the action of these two forces (F _reverse >F _f ), medium 2 is blocked at the separation door gap .

If the front ends of the stacked media are not aligned, as shown in Figure 11, the medium 2 first enters the separation door gap. At this time, since the reverse wheel has been completely blocked by the medium 2, the medium 1 is only affected by the medium 2. The action of friction (F _f ), and under the action of F _f , together with the medium 2, pass through the separation door gap, forming a double tension fault.

For the above-mentioned situation, the sheet medium separating device provided by the present embodiment adds a group of damping wheels coaxial with the banknote separation wheel at the separation door gap. 1 Provide an additional resistance (F _damping ), because F _damping >F _f , so the medium 1 is blocked at the separation door gap under the action of F _f and F _damping , so as to ensure that the media stack with non-aligned front ends can still be normal Realize sheet-by-sheet separation.

The layout relation of damping wheel, separation wheel and reverse wheel can be flexibly adjusted according to needs, as shown in Fig. The wheel is located in the center of the two banknote wheels, placed coaxially, and there is no bite intersection between the damping wheel and the reverse wheel.

When it is necessary to change the separation resistance of the damping wheel, it can be arranged as shown in Figure 13. The main difference between it and Embodiment 1 is that the damping wheel and the reverse wheel are unilaterally engaged, so this arrangement can provide greater separation resistance. . It can also be arranged as shown in Figure 14. The main difference from Embodiment 1 is that the damping wheel is located in the center of the separation wheel, so it is engaged with the reverse wheel on both sides. This arrangement can provide greater separation than the above two resistance.

What is disclosed above is only a preferred embodiment of the utility model, and of course the scope of rights of the utility model cannot be limited by this. Therefore, equivalent changes made according to the patent scope of the utility model are still covered by the utility model range.
