Description

The present invention claims the priority of a Chinese patent application filed on October 22, 2012, filed by the Chinese Patent Office, Application No. 201210405536.2, entitled "A Paper Media Separating Device", the entire contents of which are The citations are incorporated herein by reference. Technical field

The present invention relates to a sheet-like medium processing technique, and more particularly to a sheet-like medium separating device by sheet.

Background technique

The financial instruments processed on the financial instruments need to be installed to identify the processed financial instruments for the identification process. For example, to realize the one-by-one identification processing of the stacked financial notes to be processed, it is necessary to separate them one by one, for example, the current automatic depositing and dispensing machine, in order to realize the identification processing of the stacked banknotes to be processed one by one, Then, it is necessary to sort and stack the plurality of banknotes one by one and perform identification processing. In the sorting process of the banknotes, the medium separating device is required to separate the banknotes one by one from the banknote stack, so that the banknotes are carried out in the subsequent devices. Detection, classification. In the process of sorting, the banknotes pass through the billiard gate gap one by one under the action of the bill-carrying wheel, the dividing roller and the reversing wheel, achieving the purpose of separating one by one. However, due to the randomness of the stack of banknotes, it is easy to affect the sorting effect due to the different stacking shapes of the banknote stack. Specifically, when the stacking shape of the front end of the banknote stack (ie, toward the direction of the billiard gate gap) is a shape such as "inverted triangle", "" shape, and front end edge misalignment shown in FIG. 1, it is easy in the sorting process. Causes two or more banknotes to be in contact with the banknote wheel at the same time, and because of the presence of the banknotes above, the banknotes below are blocked from contacting the reversing wheel, so that the two banknotes are simultaneously dispensed by the conveying force of the banknote roller The door gap is taken away by the follow-up mechanism, causing heavy or continuous banknotes.

In order to solve the above problem, the existing paper-based medium separating device adopts a baffle 013 which is inclined toward the billiard gate gap as a reference wall for the front end of the banknote stack, as shown in FIG. 2, when the user goes to the banknote When the banknote stack is placed in the mouth, it is necessary to artificially push the stack of banknotes toward the baffle so that the front ends of the banknote stacks are aligned to form a "positive triangle" shape that is easily sorted by the separation mechanism. However, this method is not reliable in the actual implementation process because it requires the assistance of the user.

Summary of the invention

An object of the present invention is to provide a paper-based medium separating device for correcting stacking shapes of stacked sheets of paper to be separated, so that the separating end of the paper-based medium to be separated forms a "positive triangle" shape which facilitates separation by sheet. .

This paper type media separation device includes the following mechanisms:

a medium separating mechanism, comprising: a dividing roller assembly that supplies friction to the separating mechanism to the medium conveying mechanism; and a reverse wheel assembly opposite to the dividing roller assembly and rotating in the opposite direction, the dividing roller assembly and the reverse wheel Forming a bill gate gap between the components;

a media conveying mechanism comprising a rear pressure roller set, a conveyor belt pulley and a conveyor belt thereon that receive the paper successfully separated by the media separation mechanism and transported downward;

a medium aligning mechanism for aligning the front end of the banknote stack into a "positive triangle" shape for facilitating banknote dispensing, the medium aligning mechanism having a damper wheel set including a rubber wheel and at least one side of the friction A sheet and a damper spring and a spring flap, the rubber wheel being in resilient contact with the bill wheel and located between the bill gate and the stack of sheet media.

Preferably, the resistance of the rubber wheel to the paper is less than the dividing force of the dividing wheel set, but at the same time greater than the maximum friction between the banknotes.

Preferably, the damper wheel set is disposed on the movable end of the cantilever pivoted at one end by a rotating shaft, and the damper wheel is pressed against the bill wheel assembly by an elastic member.

detailed description

In order to further illustrate the present invention, a preferred embodiment of a paper-based media separation device for use in a financial self-service device of the present invention will be described below in conjunction with the illustration, which separates the stacked banknotes one by one and delivers them to subsequent mechanisms for processing.

Referring to Figures 3 through 8, the paper type media (hereinafter referred to as banknote) separating device includes the following mechanisms:

a medium separating mechanism 016, comprising a dividing roller assembly 001 for providing a frictional force to the medium conveying mechanism 018 for separating the banknotes, and a reversing wheel assembly 002 opposite to the dividing roller assembly 001 and rotating in the opposite direction, the dividing roller assembly A billing gate gap G is formed between the 001 and the reversing wheel assembly 002; for separating the banknote stacks one by one.

The media pickup mechanism 017 includes a banknote wheel set 006 that is placed in contact with the entire stack of banknotes and that is responsible for pushing the contacted banknotes into the media separation mechanism 016.

The medium conveying mechanism 018 includes a rear pressing wheel set 004 that receives a single banknote successfully separated by the medium separating mechanism 016 and is conveyed downward, a conveying pulley 005 and a conveying belt 020 thereon. When the banknote is separated from the medium separating mechanism 016, the rear pressure roller group 004 presses the banknote against the conveyor belt, so that the banknote is quickly transported away by the high speed moving conveyor belt 020.

And a medium alignment mechanism 019 having a damper wheel assembly 003 including a rubber wheel 007, friction plates 010 and a damper spring 011 stacked on both sides, and a spring stop 012, wherein the friction plate 010 is at the damper spring 011 It is pressed against the rubber wheel 007 to provide resistance to the rubber wheel 007. The rubber wheel 007 is in resilient contact with the dispensing wheel set 001 and is located between the dispensing door gap G and the stack of paper-like media. The damper wheel assembly 003 is disposed on the movable end of the support frame 009 which is pivoted at one end by a rotating shaft 0091, and the rubber wheel 007 is pressed against the dividing wheel set 001 by a torsion spring 015. In the case of media sorting, the banknotes passing through the media aligning mechanism 019 are all subjected to the resistance of the damper wheel assembly 003 to form a "positive triangle" shape which facilitates the subsequent media separation mechanism 016 for banknote sorting.

Referring to Figure 9, the specific working process of the medium alignment mechanism 019 of the device will be further described. When the stack of banknotes whose front ends are not aligned is pushed by the aforementioned medium conveying mechanism 018 to the medium aligning mechanism 019, since the medium aligning mechanism 019 is pressed against the dividing roller assembly 001, the banknote stack will now stay at the medium aligning mechanism 019. Damping wheel 003 front. At this time, the dividing roller assembly 001 is rotated, thereby driving the lowermost banknote a in the banknote stack to be transported forward. Since the friction of the banknote roller assembly 001 to the banknote a is greater than the friction between the banknotes a and b, the banknote a is smoothly transferred to the banknote gap G. For the banknote b above the banknote a, it has a tendency to move forward by the frictional force of the banknote a. However, since the damper wheel assembly 003 has resistance to the banknote b, there are the following cases: (1) When a and b are When the friction is small, the banknote b is blocked by the damper wheel and cannot advance; (2) When the friction between a and b is large, the banknote b moves relatively slowly with respect to a due to the resistance of the damper wheel, and thus is slower than a. Reach the bill gate gap G. In both cases, both of the a and b are prevented from being pushed to the bill gate in an "inverted triangle" state.

For the banknotes stacked in an arbitrary posture, when the above actions are repeated, the banknotes are gradually formed in the process of passing through the medium alignment mechanism 019 to enter the banknote gap G in a "positive triangle" shape, thereby preventing heavy banknotes and banknotes. occur.

Referring to Figure 7, when the banknote stack reaches the front of the banknote gap G in a "positive triangle" shape At this time, the banknote roller assembly 001 is in contact with the lowermost banknote of the banknote stack stacked in a "positive triangle" shape. When the dispensing roller assembly 001 rotates, the rubber 021 thereon drives the lowermost banknote to advance, because the frictional force of the dispensing roller assembly rubber 021 acts on the banknote, which is greater than the frictional resistance of the reverse wheel assembly 002 acting on the banknote. The balance of the remaining banknotes against the frictional resistance of the banknotes, therefore, the banknotes are forwarded and passed through the banknote gate G, while the remaining banknotes in the banknote stack are blocked by the counter wheel assembly 002 outside the banknote gap G. When the banknotes sent by the dispensing wheel assembly 001 are in contact with the rear pressing wheel set 004, the rear pressing wheel set 004 is pressed against the conveying belt 020 to be quickly taken away, thereby completing a banknote from the banknote stack. Separation.

The above is only a preferred embodiment of the present invention. It should be noted that the above preferred embodiments are not to be construed as limiting the present invention. The technical solution claimed in the present invention is not only applicable to the processing of banknotes in the financial field, but also to processing such as checks. Or other stacks of paper-like media that require a single sheet separation, and thus, those skilled in the art can make several improvements and refinements without departing from the spirit and scope of the invention. It should be considered as the scope of protection of the present invention.
