The present invention relates to a separator roller spacing device of a bill counter.

With the increase of the population and the development of the industry, the amount of currency gradually increases, especially as the ratio of paper money in the currency increases, banknote counters are indispensably used in various financial institutions and other places where money is handled. The bill counter can count a large amount of bills very quickly and accurately, as well as find a counterfeit bill by installing various sensing devices therein depending on the type.

For accurate counting in such a bill counter, it is important to sense the thickness of bills to be counted so that the bills are transferred one by one in the counter. In this way, the separator roller allows the bills to be conveyed one by one.

The separator roller is paired with the feeding roller and passes the banknote between the feeding rollers. The separator roller does not rotate depending on the type and rotates in the same direction as the feeding roller.

In any case, the bill to be counted passes between the separator roller and the feeding roller, so the distance between the outer peripheral surface of the feeding roller and the outer peripheral surface of the separator roller should be equal to the thickness of the banknote to be passed. If the interval is narrower than the thickness of one bill, the counter will not pass because the bill will not pass. If it is wider than two bills, two bills will pass at a time, so the correct count cannot be expected. .

As such, the precision of the spacing of the separator roller with respect to the feeding roller is a very important factor, so all the bill counters are provided with a separator roller spacing device.

1 is a view illustrating a separator roller spacing adjusting device installed in a conventional bill counter.

As shown, the conventional banknote counter 11 has a case 13 having an entry and exit 39 and 41 for entering and exiting a banknote and providing an internal space, and located in front of the inlet of the case 13 and counting. A kick roller 15 for supplying bills one by one to the inlet 39, a feed roller 17 and a separator roller 21 for receiving the bills supplied from the kick roller 15 and passing them therebetween; Detects a plurality of feed rollers 49 passing the banknotes passing through the feeding roller 17 along a predetermined path to the exit 41 side, a motor 43 for driving the respective rollers, and the banknotes being conveyed. And various sensors (not shown) and a controller 45. Reference numeral 19 denotes a feeding roller shaft 19 to which the feeding roller 17 is fitted.

In addition, the interval adjusting device 29 for adjusting the interval of the separator roller 21 with respect to the feeding roller 17 is also provided.

The gap adjusting device 29 is supported by the support shaft 27 and the shaft fixing part 25a, both ends of which are rotatably supported in the casing 13 and parallel to the feeding roller shaft 19. A holding roller 25 fixed to the shaft 27 and rotatable in an arrow a direction according to the axial rotation of the support shaft 27, and a separator roller fixed to the holding bracket 25 via a separator roller shaft 23. 21). As a result of the rotation of the separator roller 21 relative to the feeding roller 17, the gap between the holding bracket 25 and the a direction of arrow a is widened.

In addition, a rotating arm 31 is fixed to the support shaft 27 separately from the holding bracket 25. The rotating arm 31 is a block in which the lower end is obliquely extended upward with the lower end fixed to the support shaft 27, and a pressing surface 31a is provided at one side thereof. Since the lower end of the rotating arm 31 is fixed to the support shaft 27, the separator roller 21 moves forward with respect to the feeding roller 17 when the rotating arm 31 is rotated.

On the side of the rotating arm 31, a fixed block 33 fixed to the case 13, and a adjusting screw through the fixed block 33 horizontally so that the end portion of the thread portion is in contact with the pressing surface (31a) (35) and the leaf spring (37) to elastically press the bottom surface of the head portion of the adjustment screw 35 in a fixed state to the fixing block 33 so that the adjustment screw 35 does not rotate by vibration or other forces. ) Is provided.

In addition, the rubber plate 35a is fixed to the bottom surface of the head of the adjustment screw 35 so as to enlarge the frictional force with the leaf spring 37. In addition, the pivot arm 31 is connected to the fixed block 33 by a tension spring (47).

Accordingly, when the adjusting screw 35 is rotated by hand to rotate the screw back, the rotating arm 31 rotates in the direction of the arrow b by the tension force of the tension spring 47, and thus the holding bracket 25 also arrow. The separator roller 21 is opened from the feeding roller 17 by turning in the a direction.

When the adjusting screw 35 is rotated in the opposite direction, the threaded portion of the adjusting screw 35 presses the pressing surface 31a of the rotating arm 31 to rotate in the opposite direction to the arrow b direction, and the separator roller 21 feeds accordingly. The gap is narrowed by moving toward the roller 17 side.

However, the conventional gap adjusting device 29 has a problem that it is not easy to adjust the gap of the separator roller 21 with respect to the feeding roller 17. That is, because the length of the retracted distance of the threaded portion corresponding to the rotation angle of the adjustment screw 35 head cannot be estimated, turn the adjustment screw to some extent by mobilizing the empirical sensation, pass the banknote through the banknote, and adjust the adjustment screw if the banknote does not pass. Loosen (35) to open the gap, and when two banknotes pass through, it is necessary to make troublesome setting work such as tightening the adjusting screw to close the gap.

In addition, even if the leaf spring maintains the position of the adjustment screw, there is a problem that the adjustment screw may be returned to the direction of loosening due to the use of the old or the vibration applied to the counter when the counter moves.

The present invention has been made to solve the above problems, and a plurality of irregularities are formed on the outer circumferential surface of the head of the adjustment screw for supporting the separator roller toward the feeding roller side, and even if the irregularities are applied by pressing the irregularities with the pressure ball, various vibrations from the outside are applied. Since there is no fear of adjusting screw return, the gap between the separator roller and the feeding roller is always constant, and the gap between the unevenness is constant. It is an object of the present invention to provide a separator roller gap adjusting device for a banknote counter with accurate gap adjustment since the screw feeding distance can be calculated.

In order to achieve the above object, the present invention provides a bill counter including a case having a cash inlet and outlet, and a feeding roller and a separator roller installed in the case and passing bills entered therethrough one by one. As installed to adjust the distance of the separator roller relative to the feeding roller,

The shaft fixing part 25a of the holding bracket 25 is fixed to the center portion of the support shaft 27. A separator roller shaft 23 is provided on the holding bracket 25, and a separator roller 21 is fixed to the separator roller shaft 23. The separator roller 21 is fixed relative to the holding bracket 25.

On the other hand, the rotating arm 31 is fixed to one end of the support shaft 27, and the fixed block 55 is located on the rotating path of the rotating arm 31. The fixing block 55 is fixed to the frame 69 as described above.

Figure 4 is an exploded perspective view for explaining a separator roller spacing device according to an embodiment of the present invention.

As shown, the pivot arm 31 is fixed to one end of the support shaft 27, and the stationary block 55 is located at a position corresponding to the pressing surface 31a of the pivot arm 31. As shown in FIG. .

In addition, the fixing block 55 is fitted with an adjustment screw 57. The adjustment screw 57 is a state in which the threaded portion penetrates the fixing block 55 and is connected to the pressing surface 31a.

The ball support plate 71 is closely coupled to the side of the fixed block 55. The ball supporting plate 71 is a rectangular plate having a predetermined thickness, a part of which is located close to the outer circumferential surface of the head 57a of the adjusting screw. Further, a ball receiving hole 71a is formed at one side of the ball supporting plate 71.
