In general, businesses and financial institutions that deal with a lot of bills, due to the recent increase in counterfeit crime has been increasing the task of identifying whether the bill forgery, and the task of classifying various types of bills by each type.

In addition, due to the rapid industrial development, office automation has become commonplace, and banknote exchangers and cash dispensers have been widely installed in various places in the streets as well as financial institutions. In order to promote the proper operation and operation of financial automation devices such as paper money exchangers and cash dispensers, banknotes that are clean and rated must be supplied to the financial service automation equipment. It is too inefficient to make a manual work by hand, so a bill recognition counter is used to improve this.

Hereinafter, a conventional banknote counter will be described in detail with reference to the accompanying drawings.

1 is a side cross-sectional view showing a banknote transfer path of a conventional banknote counter.

As shown in FIG. 1, a conventional banknote counter includes a body 100 into which bills are inserted and transported, various rollers for transporting bills, various sensing means for detecting whether bills are normal bills, and bills. Stack wheel 400 for stacking one by one, and the main motor 510 and the wheel motor 520 for bill transfer and stack wheel 400 rotation is configured.

In the body 100, a banknote inlet 102 into which bills are inserted, a conveying line 110 to which the inserted bills are transported, and a loading part 104 and a transporting part 106 into which the transported bills are loaded and taken out It is provided. In addition, the transfer line 110 is curved to be divided into the first half and the second half. Accordingly, the feed roller is also classified into a first half feed roller 262 mounted at the first half of the transfer line 110 and a second half feed roller 264 mounted at the second half of the transfer line 110. The first half feed roller 262 and the second half feed roller 264 are fixed to the respective shafts 261a, 261b, 261c, 261d, and 261e.

Each of the feed rollers is rotated by receiving the power of the main motor 510 through the motor belt 512.

Looking at the operation of the conventional bill counter is configured as follows.

When a plurality of bills are inserted into the bill insertion slot 102, the bills located at the bottom of the plurality of bills loaded by the pickup roller 210 are fed to the feed roller 220, and other bills not fed are not fed. Feeding is prevented by the gate roller 230. At this time, the front of the gate roller 230 is provided with a pressure roller 240 for close contact with the feed roller 220, the bill is fed, the back of the gate roller 230 is a bill passing the pressure roller 240 An alignment roller 250 for aligning is provided.

Therefore, the paper money fed is aligned by the alignment roller 250 without being twisted or bent and transferred to the first half feed roller 262. The first half of the transfer line 110 is equipped with a bill detection sensor 310 and the image information input sensor 320 for detecting the authenticity and damage of the bill and accepting the image information of the bill, the transfer line 110 Banknotes passing through the first half of the) pass through the latter half of the transfer line 110 after being determined by the banknote detection sensor 310 and the image information input sensor 320.

Banknotes past the second half of the transfer line 110 are sorted by the switching guide feather 120 and loaded into the loading unit 104 or the carrying out unit 106. At this time, banknotes normally counted are stacked in the stacking unit 104, and bills determined as abnormal banknotes are stacked in the carrying out unit 106. In addition, the banknotes stacked on the stacking unit 104 are stacked one by one by the stack wheel 400 which is rotated by the wheel motor 520 and are stacked on the stacking unit 104.

At this time, the feed rollers are shafts 261a, 261b, 261c, 261d, and 261e are inserted and coupled to the center of rotation, and pulleys are coupled to both ends of the shafts 261a, 261b, 261c, 261d, and 261e, respectively. Each pulley coupled to the shafts 261a, 261b, 261c, 261d, and 261e is configured to be wound by one pulley swivel belt and rotate or stop at the same time. It rotates at the same speed and the bills are transferred at the same speed from loading to discharge. In addition, the interval between the leading banknote and the trailing banknote is set to the minimum distance that can distinguish the banknotes so that the bills can be counted more quickly.

However, as mentioned above, if the gap between the leading and trailing banks is not sufficiently secured, there is a problem that the leading and trailing banks may interfere with each other when the bills are sorted by the switching guide blade 120. That is, if the interval between the leading and trailing banks is set too wide, the speed of counting the bills becomes too slow, and if the interval between the leading and trailing banks is set too narrow, interference between the leading and trailing banks may occur. Will occur.

The present invention has been proposed in order to solve the above problems, by increasing the transfer speed of the bill in the section in which the preliminary bill and the trailing bill is classified, the banknote by the switching guide feather 120 while maintaining the counting speed of the bill as it is It is an object of the present invention to provide a bill discharge accelerator configured so that interference between the leading and trailing bills is not generated in the section in which the is classified.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of a banknote discharge accelerator according to the present invention. The same reference numerals are given to the same parts as in the conventional structure, and detailed description thereof refers to FIG. 1.

Figure 2 is a side view of a first embodiment of a banknote discharge accelerator according to the present invention, Figure 3 is a side view of a second embodiment of a banknote discharge accelerator according to the present invention.

Banknote discharge accelerator according to the present invention, two or more transfer rollers (262, 264) (see Fig. 1) arranged in the conveying direction of the banknotes for conveying the banknotes, and the sensing means for detecting the banknotes being conveyed (310, 320) (See FIG. 1), shafts 261a, 261b, 261c, 261d, and 261e mounted through the respective feed rollers 262 and 264, and the shafts 261a, 261b, 261c, 261d, and 261e. A pulley 610 and 620 coupled to one or both ends of the pulley 610 and a pulley rotating belt 700 surrounding the pulleys 610 and 620 such that the pulleys 610 and 620 rotate integrally. .

In addition, the section in which the banknotes are transferred, the sensing section (a) that the banknotes are transferred while detecting the information of the banknotes conveyed by the sensing means (310, 320) and whether or not the authenticity of the banknotes using the detected banknote information During the discrimination is divided into a discrimination section (b) for transferring the bills, a separation section (c) for distinguishing between normal and abnormal bills, and a discharge section (d) for discharging the bills to the outside. That is, the banknotes introduced from the outside, the normality is determined while passing through the detection section (a) and the discrimination section (b) sequentially, and separated from the separation section (c) so that the normal and abnormal banks can be loaded separately. The separated bill is discharged to the outside through the discharge section (d).

As such, the feed rollers and the pulleys 610 and 620 are provided at the ends and ends of the shafts 261a, 261b, 261c, 261d, and 261e, respectively, and the pulleys 610 and 620 have one pulley rotating belt 700. By rotating by all the transport rollers are rotated at the same time is a structure that is commonly used in the conventional bill counter, detailed description thereof will be omitted.

At this time, the biggest feature of the present invention is that not all pulleys are formed in the same size, but some of the pulleys located on the side where the banknotes are discharged are formed small. That is, as shown in FIG. 2, a first pulley 610 having a relatively large diameter is mounted on the shafts 261a, 261b, and 261c mounted in the detection section a, the determination section b, and the separation section c. The second pulley 620 having a diameter smaller than that of the first pulley 610 is mounted to the shafts 261d and 261e mounted in the discharge section d.

As such, the feed roller connected to the second pulley 620 having a small diameter and one shaft 261d and 261e rotates faster than the feed roller connected to the first pulley 610. In the discharge section d, the sensing section ( Banknotes are transferred faster than a), the discrimination section (b), and the separation section (c). The rapid transfer of the bill means that the interval between the preceding banknote and the following banknote is increased, so that the time required for the switching guide feather 120 shown in FIG. 1 to rotate can be sufficiently secured. There is an advantage that the risk of interference between the following currencies is very low.

In addition, in the detection section (a) for detecting various information of the bill, it is difficult to accurately judge the various information of the bill when the conveyance speed of the bill is too fast. In the remaining sections after), increasing the conveyance speed of the bill does not cause a big problem. Rather, in the remaining sections past the sensing section (a), it may be advantageous to increase the transfer speed of the bill to increase the interval between the leading and trailing bills to prevent jams and jams.

Therefore, the bill discharge accelerator according to the present invention, as shown in Figure 3, the pulley coupled to the shaft (261c, 261d, 261e) mounted on the discharge section (d), the discrimination section (b) and the separation section (c) It can be applied to the pulley having a small diameter, that is, the second pulley 620.

In addition, when it takes a while to determine the authenticity of the bill, only the pulley coupled to the shaft (261c, 261d, 261e) mounted on the discharge section (d) and the separation section (c) second pulley (620) The pulley coupled to the shaft mounted in the determination section (b) may be applied to the first pulley 610 having a larger diameter than the second pulley 620.

Figure 4 is a perspective view showing a feed roller 220 and its peripheral configuration included in the bill discharge accelerator according to the present invention, Figure 5 and Figure 6 is a plan view showing a use example of the bill discharge accelerator according to the present invention. 7 is a front view showing the mounting positions of the clutch and the brake.

In general, the bill counter is provided with a banknote contact portion 226 on a portion of the outer circumferential surface of the feed roller 220 for supplying the loaded bills to the feed roller one by one, and is coupled through the rotation axis of the feed roller 220 A feed roll shaft 810 and a feed roll pulley 812 coupled to one or both sides of the feed roll shaft 810 are wound around the pulley rotating belt 700.

As shown in FIG. 5, the banknote P supplied to the feed roller 220 has a front end contacting the tip side (upper side in FIG. 5) of the banknote contacting part 226 to the frictional force with the banknote contacting part 226. By the feed roller side. However, when the banknote P introduced into the feed roller slips, a phenomenon in which the tip of the banknote P comes in contact with the rear end side (upper side in FIG. 6) of the banknote contact unit 226 also occurs. In this case, since the interval between the trailing banknote is narrowed by the distance in which the banknote P slips, there is a problem in that a jam and a jam phenomenon occur.

Therefore, the banknote discharge accelerator according to the present invention, in order to secure a wide interval between the leading banknote and the following banknotes, the feed roll wheel 820 is formed with a slit 822 is coupled to the feed roll shaft 810, and Another feature is that it further comprises an optical sensor 830 for detecting the position of the slit 822 to detect the position on the bill contact portion 226. In this case, since the feed roll wheel 820 is mounted to be integrally rotated with the feed roller 220, the optical sensor 830 detects the position of the slit 822 formed on the feed roll wheel 820 to contact the banknote. (226) The above position can be determined. In this embodiment, only the structure for detecting the rotation angle of the feed roll wheel 820 by detecting the position of the slit 822 by mounting the optical sensor 830 on the rotation path of the slit 822, but the optical In addition to the sensor 830, a method using a magnetic sensor or an ultrasonic sensor may also be applied.

Therefore, the bill discharge accelerator according to the present invention, as shown in Figure 6, when the point that the banknotes supplied by the feed roller 220 in contact with the bill contact portion 226 is out of the normal section, the feed roll It is configured to interrupt power transmission between the pulley 812 and the feed roll shaft 810 to idle the feed roll pulley 812 by a predetermined angle. In this way, when the feed roll pulley 812 is idling by a preset angle, the trailing bank is introduced late by the idling angle so that a sufficient distance from the leading bank is secured.

As a means for idling the feed roll pulley 812, various methods may be applied. For example, as illustrated in FIG. 7, the feed roll pulley 812 may be idling using a clutch that connects or releases power transmission between the feed roll shaft 810 and the feed roll pulley 812. .

The clutch is provided with an electromagnet therein, and normally, the contact disk 850 coupled to the feed roll shaft 810 is brought into contact with the feed roll pulley 812. When the operation signal is applied, the contact disk 850 is applied. ) Is spaced apart from the feed roll pulley 812 for a while. As such, when the contact disk 850 is spaced apart from the feed roll pulley 812, the feed roll shaft 810 does not receive the rotational force even when the feed roll pulley 812 rotates, the feed roller 220. ) Will not rotate for a while.

At this time, even if the power transmission between the feed roll shaft 810 and the feed roll pulley 812 is released, the feed roller 220 and the feed roll shaft 810 can be rotated by the rotational inertia, The bill discharge accelerator according to the present invention may further include a brake 860 that blocks inertia rotation of the feed roll shaft 810 when power transmission between the feed roll shaft 810 and the feed roll pulley 812 is released. have. That is, the brake 860 is fixedly coupled to the fixing member, the feed roll shaft 810 when the power transmission between the feed roll shaft 810 and the feed roll pulley 812 by the operation of the clutch is released. The feed roller 220 and the feed roll shaft 810 are momentarily stopped by grabbing.

As such, the clutch for implementing the rotational force transmission and blocking to the rotary shaft and the brake 860 for preventing the inertia rotation of the rotary shaft are commercially available, and a detailed description thereof will be omitted.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment, Comprising: It should be interpreted by the attached Claim.
