Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a switching mechanism for dispensing and collecting banknotes in a cash dispenser or the like.

(Prior Art) In a device such as a cash dispenser that counts and dispenses the required number of banknotes in response to a user's request, a temporary storage section for banknotes is used to prevent over- or under-dispensing due to incorrect counting of banknotes. It is common practice to set up a counter and pay out the banknotes all at once after confirming that the required number of banknotes have been deposited in the unit, and in the unlikely event that the number of banknotes is excessive or insufficient, the banknotes are collected into the device and the banknotes are counted again. It is.

At this time, a gate is required to switch the banknote conveyance path from the temporary storage section to the payout port and the banknote transfer path to the collection section, and its configuration is such that the banknotes are sandwiched and conveyed between the pair of conveyor belts 1 and 2 as shown in Figure 2. The banknotes 3 are stopped and stacked at a stopper 4 in the middle of the conveyance path, and using the curves 5 and 6 of the inner and outer surfaces of the stopper 4, the accumulated banknotes are transferred to the collecting section 7 or via the banknote delivery and conveyance path 8 to the payout port. It was common to pay out to 9.

However, when adopting such a configuration, there is a problem in that jams occur frequently because it is necessary to transfer the stack of banknotes between separated conveyance paths and the conveyance path needs to be curved, and this tendency is particularly problematic. This flaw was especially noticeable when handling small numbers of curled banknotes.

(Object of the Invention) The present invention has been made in order to eliminate the above-mentioned defects in the bill dispensing/recovery switching gate of the conventional cash dispenser. It is an object of the present invention to provide a bill dispensing/recovery switching mechanism that prevents jamming of bills by not transferring or bending the bills.

(Summary of the Invention) In order to achieve the above-mentioned object, the present invention is configured such that the entire temporary storage section for banknotes is swung toward the banknote dispensing port or the collection section in response to banknote dispensing or collection, respectively. do.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

FIGS. 1a and 1b are a link configuration diagram and a detailed plan view thereof, respectively, showing an embodiment of the banknote dispensing/recovery switching mechanism according to the present invention.

In this figure, reference numerals 10 and 10 denote a fixed conveyance path for banknotes, and the banknotes conveyed through this path while being counted one by one are placed in front of the banknote temporary storage section 11 located at a somewhat lower level. It is made to fall onto the belt conveying device 12. The end pulley shaft 13 of the fixed conveyance path 10 and the end pulley shaft 14 of the lower belt conveyance device 12 are connected by a link 15,
15 and the lower belt conveying device 12 itself is urged upwardly with respect to the link 15 by a spring, and the link 15
This is kept horizontal by regulating it with pins 16. Further, an upper belt conveying device 17, which is paired with the lower belt conveying device 12, and the shaft 13 are connected by a link 18, which is also biased upward by a spring force, and is erected on the side wall of the link 18. The pin 19 is configured to keep the upper belt conveyor 17 substantially parallel to and spaced apart from the lower belt conveyor 12.

FIG. 2B is a plan view showing an embodiment of a mechanism for arranging each component connected by links to the above-mentioned posture, and shows the pulley shaft 13 of the fixed bill conveyance path 10. The shaft 13 is supported as a triple shaft through bearings at appropriate positions on the machine frame, and a belt pulley 21 for driving the fixed banknote transport path 10 by a timing belt 20 is attached to the shaft 13, and the banknote temporary storage section 11
Upper and lower belt conveying devices 17 and 1 constituting 1, respectively
A two-stage pulley 22 for driving 2 is fixed.

Further, an intermediate shaft 23 is disposed inside the shaft 13 via a bearing, and the links 15, 15 are fixed to both ends of the shaft 23 to connect it to the pulley shaft 14 of the lower belt conveying device 12. Also, the link 1
A belt pulley 25 for rotating the intermediate shaft 23 by a required angle by a timing belt 24 is fixed to the outside of one of the shafts 5 and 15, and is driven by a motor (not shown).

Furthermore, a torsion shaft 26 using a torsion bar is installed inside the intermediate shaft 23 via a sliding bearing.
The ends of the shaft are fixed to appropriate positions on the frame, and the links 18, 18 supporting the upper belt conveying device 17 are rotated by a predetermined angle about the pulley shaft 13 from the position shown in FIG. 1a. If it is fixed to the torsion shaft 26 in a clockwise rotated position and the links 18, 18 are rotated to the illustrated position, the torsion shaft 26 will be twisted and a spring force in the counterclockwise direction will be generated. Belt pulleys 28, 28 are fixed to the torsion shaft 26 for rotating the torsion shaft 26 by means of timing belts 27, 27 against the spring force.

On the other hand, the link 15 fixed to the intermediate shaft 23,
15 is the pulley shaft 1 of the lower belt conveying device 12
4, arms 29, 29 supporting the entire lower belt conveying device 12 and a coil spring 3;
0 and 30, and the two are engaged by latches 31 and 31, so that the angle between them is kept at a desired value, and the lower belt conveying device 12 is held horizontally. Further, in order to drive this lower belt conveying device 12, a pulley 33 for winding a wire 32 is fixed to the pulley shaft 14 and one of the two-stage pulleys 22 fixed to the shaft 13. 13 and 14 are rotated in the same direction.

Similarly, a pulley 35 for driving this belt conveying device is fixed to the pulley shaft 34 of the upper belt conveying device 17 connected to the link 18, and a wire 36 is connected crosswise between this pulley 35 and the other of the two-stage pulley 22. Winding the upper and lower belt conveying devices 17 and 12
The running direction of the belt contact surfaces is made to coincide with each other.

Incidentally, the bar projecting above the lower belt conveying device 12 is a bill stopper 37 for temporarily storing banknotes, and is disposed in a gap between the belt rows to stop the banknotes temporarily when the banknote temporary storage section 2, which will be described later, swings. It is fixed at a position to avoid interference with the members that make up the storage section.

The banknote payout/collection switching mechanism of the present invention constructed as described above operates as follows.

First, if the machine is in the bill dispensing standby state, the third
As shown in FIG. 1A, the conveying belt surface of the lower belt conveying device 12 is located at a position slightly lower than that of the fixed conveying path 10 and separated from the upper belt conveying device 17.

Now, when a required number of banknotes are fed one by one through the fixed conveyance path 10 and into the lower belt conveying device 12 according to a user's request, this conveying device is transferred to the wires 32 and 36 together with the upper belt conveying device 17. The banknote is then rotated to move the banknote until its tip reaches the stopper 37. When the banknote stacking is completed, the banknote transport system stops in the state shown in Fig. 3b, and it is finally determined whether or not the number of banknotes stacked is the desired value, and if there is an excess or deficiency in the number of banknotes, The timing belts 27, 2 are activated by a command from a machine controller (not shown).
7 and rotates clockwise in the figure against a torsion bar 26 that connects the link 18 thereto.

As a result, the upper belt conveying device 17 rotates while pressing the lower belt conveying device 12, as shown in FIG.
6, the entire banknote temporary storage section 11 swings toward the banknote collection container 7.

If the banknote transport systems 10, 12, and 17 are driven at the same time as the swinging of the banknote temporary storage section 11 is completed, the banknotes are discharged into the collection container 7 and the collection is completed.

On the other hand, if it is determined that the banknote count is normal and the user can pay out the banknotes as is, the timing belt 24 is driven to rotate the link 15 counterclockwise in the figure as shown in FIG. 3d. .

By doing so, the lower belt conveying device 12 is pressed by the upper belt conveying device 17 while the banknotes are stacked thereon, and the banknote temporary storage section 11 swings so that the entire banknote temporary storage section 11 is oriented toward the banknote dispensing port. At the same time as the above-mentioned rotation ends, the bill conveying systems 10, 12
Needless to say, by driving the banknotes 17 and 17, the banknotes are discharged to the payout port 9 and delivered to the user's hands. In this case, the banknote transport speed should be reduced to prevent the banknotes from jumping over the payout port 9.

Incidentally, in any of the operations shown in FIGS. 3c and 3d, as is clear from the explanation of the configuration in FIGS. It has a degree of rotational freedom within a certain range, and the lower belt conveying device 12 also has a degree of freedom of rotation in the clockwise direction in the figure with respect to the link 15, and is biased by the spring 30, so that it does not carry banknotes. It is possible to reliably hold the material between the two conveyor belts regardless of the amount of accumulated material, and therefore there is almost no possibility of mis-feeding occurring.

(Effects of the Invention) Since the present invention is configured and operates as described above, there is virtually no transfer or direction change in the banknote conveyance path, thus minimizing the frequency of occurrence of jams and improving the payout of banknotes. In addition, since it is possible to almost eliminate feed errors during collection, if it is applied to a cache dispenser etc. that requires absolute accuracy, it will be extremely effective in reducing service intervals and achieving user satisfaction.
