2. Description of the Related Art Conventionally, a coin pumping device used in a coin processing machine is used to dispense coins dispensed from a coin-type storage unit or the like at the time of withdrawal or collectively from a temporary holding unit at the time of deposit return. It is used to pump returned coins and other coins from the lower part of the fuselage to the upper part.

In this coin feeding apparatus, generally, a belt having a plurality of protrusions for locking coins on its surface is obliquely arranged with respect to the vertical direction, and the coins are locked to the protrusions by this belt. A coin pumping device for pumping is used. However, in this coin hoisting device, since the belt is arranged obliquely with respect to the vertical direction, it may take up a large installation space and it may be difficult to cope with downsizing of the coin processing machine.

Further, for example, as described in Japanese Patent Laid-Open No. 6-103439 or Japanese Patent Laid-Open No. 5-131061, there is a coin lifting device for vertically lifting coins. With this coin lifting device, coins are received one by one in a standing posture in which the coins are vertically erected between the lifting guides provided in the vertical direction or in the lifting passage, and the coins are distributed to the side portions of the lifting guide and the lifting passage. By the rotation of the installed spiral body, the spiral body pushes up coins one by one while maintaining the standing posture between coins in the lifting guide and in the lifting passage.

Since the coins in the passage are pushed up and lifted while keeping the standing posture, it is necessary to feed the coins in a line in a standing posture in which the coins stand vertically.

Therefore, as described above, in the coin processing machine, withdrawal coins that are ejected in parallel from the coin-type accommodating portion or the like at the time of withdrawal, or return coins that are collectively ejected from the temporary withdrawal portion when the deposit is returned. When pumping multiple unaligned coins from the lower part of the machine to the upper part, it cannot be sent to the coin lifting device as it is,
It requires the use of a special alignment mechanism to align the rows, which is a problem of complexity and size.

Further, since the coins received one by one between the lifting guides and in the lifting passage are pushed up and lifted by the spiral while maintaining the standing posture, coins that can be lifted per unit time There is a problem that the number of coins is small and it takes time to pump multiple coins.

The present invention has been made in view of the above points, and does not require a mechanism for aligning the coins to be pumped, can be simplified and downsized, and can efficiently pump coins. The purpose is to provide.

In FIG. 5, at the time of deposit processing, the deposited coins that have been inserted into the coin receiving portion are received by the coin feeding portion 2 and fed out one by one from the coin feeding portion 2 into the coin passage 3 and then by the identifying portion 4. It is identified, sorted by denomination by the sorting unit 5, and temporarily held by denomination by the temporary holding unit 6.
Overflow coins of denominations that cannot be stored because the temporary holding unit 6 and the denomination stacker unit 7 are full pass through the sorting unit 5 and are temporarily held in the overflow coin temporary holding unit 9. At the time of deposit approval, the temporary holding coins of the temporary holding unit 6 are stored in the denomination-based stacker unit 7, and the temporary holding coins of the overflow coin temporary holding unit 9 are stored in an overflow box or the like. When the deposit is returned, the temporary holding coins of the temporary holding unit 6 and the overflow coins of the overflow coin temporary holding unit 9 are discharged onto the conveyor belt 10 through a chute (not shown), and the coins are conveyed through the conveyor belt 10 and the coin lifting device 21. Returned to the receiving department.

At the time of withdrawal processing, withdrawal coins ejected one by one from the coin type stacker section 7 by the ejecting section 8 based on the deposit command are ejected onto the conveyor belt 10 through a chute (not shown), and the conveyor belt is conveyed. The coins are withdrawn to the coin receiving portion through the 10 and the coin lifting device 21.

Next, the operation of the coin hoisting device 21 will be described.

The coin C conveyed to the coin lifting device 21 by the conveyor belt 10 is discharged to the entrance chute 40, slides down the entrance chute 40, and becomes a sideways state. That is, the spiral space of the spiral rotor 23
It enters the inside of 36 and movably moves on the spiral surface 37 of the spiral surface portion 35.

The spiral rotator 23 is rotated in the lifting direction in which the spiral surface 37 of the spiral surface portion 35 is apparently moved upward by the driving of the motor M, and is transferred from the coin inlet portion 27 onto the spiral surface portion 35. The coin C moves along with the spiral surface portion 35, and as shown in FIG. 4 (a), the coin C is attached to the inner peripheral surface of the guide body 22, for example, the inner peripheral surface of the cylindrical portion 24 by the action of the centrifugal force due to the rotation. Abut. Coin C abutting on the inner peripheral surface of the guide body 22
The frictional force is generated between the guide body 22 and the inner peripheral surface of the guide body 22 to generate a drag force in the rotation direction of the spiral rotating body 23.
It stagnates for the rotation of 23, slip occurs on the spiral surface portion 35,
Pushed upward by the action of the spiral of the spiral surface portion 35,
Be pumped.

As shown in FIGS. 4 (b) and 4 (c), the coin C, which is in contact with the inner peripheral surface of the guide member 22 and rotates while sliding, has a hollow portion.
The opening 26 of the cylindrical portion 24 that enters the recess 29 and forms the recess 29.
By hooking on the corner of the edge of the spiral rotor 23
Of the spiral rotating body 23
Is more stagnant with respect to the rotation, the sliding on the spiral surface portion 35 is increased, and the spiral of the spiral surface portion 35 efficiently pushes it upward and efficiently pumps it. At this time, coin C
The peripheral edge portion of the contact portion abuts on the corner portion of the edge portion of the opening portion 26 of the cylindrical portion 24 forming the recess portion 29. However, since the point contact causes a small frictional force in the vertical direction, the drag force against the upward movement of the coin C is small,
The coin C is easily lifted. When the coin C stays, the centrifugal force stops working, and the coin C cannot stay in the recess 29 and is dragged by the spiral surface 37 to orbit.

Then, the coin C is fed while the series of states shown in FIGS. 4 (a) (b) (c) is repeated as the spiral rotor 23 rotates.

Coins C to be pumped by the spiral rotator 23
When the coin reaches the coin outlet 28, it is discharged to the outside of the guide body 22 through the coin outlet 28 by the action of the centrifugal force due to the rotation, is received by the outlet chute 41, and is guided to the coin receiving portion.

Further, in the coin inlet 27, the number of coins C received from the inlet chute 40 is not limited to one by one, and even if a plurality of coins C are received at one time, the coins are not jammed, and the coins are reliably processed. it can. Normally, when the spiral surface 37 of the spiral surface portion 35 facing the inlet chute 40 is at a lower rotational position than the bottom surface of the inlet chute 40,
The coin C in the horizontal state on 40 enters the spiral space 36 of the spiral surface portion 35 and moves on the spiral surface 37. If a large part of the coin C is placed on the spiral surface portion 35, the coin C becomes the coin inlet portion.
Even if it comes into contact with the side edge portion of 27, it is drawn into the inside of the guide body 22 by the spiral surface portion 35 that rotates, and is lifted.

As shown in FIG. 6, when only part of the coin C is placed on the spiral surface portion 35, the coin C rises up and is returned to the entrance chute 40 side as the spiral surface portion 35 rotates.

As shown in FIG. 7, when the coin C lifted on the spiral surface portion 35 does not completely enter the inside of the guide body 22 and comes into contact with the upper cover 25 of the coin inlet portion 27, the coin C
Is converted into a standing posture in the space 30 between the spiral surface portion 35 and the cover 25, and falls from the spiral surface portion 35 through the space portion 30 to prevent the coin entrance portion 27 from being caught.

As shown in FIG. 8, a plurality of coins C are piled up.
When the coins enter the coin inlet 27 at a time, the spiral rotor 23
Only the number of coins C allowed to enter the spiral space 36 of the other coins enter, and the other coins C are returned to the entrance chute 40 side.

When the optical sensor PS21 detects that a large amount of coins are fed from the conveyor belt 10 to the entrance chute 40 and a predetermined amount or more of coins C are accumulated on the entrance chute 40, the conveyor belt 10 is temporarily stopped. Then, the feeding of the coin C is temporarily stopped. If it is no longer detected by the optical sensor PS21,
The driving of the conveyor belt 10 is restarted, and the feeding of the coin C is restarted.

Further, based on the outputs of the optical sensors PS1 to PS4, the presence / absence of the coin C in the guide body 22 is detected. Optical sensors PS11 to PS14 on the conveyor belt 10, the magnetic sensor MG of the entrance chute 40, and the optical sensor PS in the guide body 22.
If no coin is detected in each of 1 to PS4, it is determined that the coin C has been completely transported, and the driving is stopped.

As described above, the coin C received in the guide body 22 is movably placed on the spiral surface 37 of the spiral rotator 23 in which the width of the spiral surface 37 is larger than the diameter of the coin having the maximum diameter to be processed. The coin C on the spiral surface portion 35 is brought into contact with the guide body 22 by the centrifugal force generated by the rotation of the spiral rotor 23, so that the coin C contacting the guide body 22 produces a reaction force in the rotating direction of the spiral rotor 23. Then, the coin C can be fed while being slid on the spiral surface portion 35. Therefore, the number of coins C received from the entrance chute 40 is not limited to one by one, and even if a plurality of coins C are received at a time, the coins can be reliably pumped without being jammed, and can be pumped. A mechanism for aligning the coins C is not required, which can be simplified and downsized, and the coins C can be efficiently pumped.

Further, since the pitch of the spiral surface portion 35 of the spiral rotary member 23 is set to be smaller than the diameter of the minimum diameter coin for processing, the coin C does not stand on the spiral surface portion 35, and the spiral surface portion 35 and the guide body 22 are It is possible to prevent bites between them. in this case,
The spiral surface portion 35 may have a pitch that allows only one coin C to enter, or a pitch that allows a plurality of coins C to overlap. By constructing the pitch such that a plurality of coins C that are overlapped can enter, the lifting capacity can be improved.

The drag generating means 33 generates a drag force on the coin C abutting against the guide body 22 by the rotation of the spiral rotator 23 in the rotating direction of the spiral rotator 23, so that the coin C
Since the coins slide on the spiral surface portion 35, the coin C can be efficiently pumped. Since the reaction force generating means 33 has a recess 29 provided in the inner surface of the guide body 22 along the up-down direction, the reaction force with respect to the coin C engaging with the recess 29 with respect to the rotation direction of the spiral rotating body 23. Can be reliably generated. Furthermore, since the opening 26 is provided in the guide body 22 along the vertical direction and the cover 25 that covers the opening 26 is provided on the outer peripheral side of the guide body 22, the recess 29 can be easily formed.

Further, on the upper side of the coin inlet portion 27 of the guide body 22, in order to provide the space portion 30 between the guide body 22 and the spiral surface portion 35 of the spiral rotator 23, the coin C can pass in the standing posture. ,
Even if the coin C lifted by the spiral surface portion 35 does not completely enter the inside of the guide body 22 at the coin inlet 27 and comes into contact with the upper side of the coin inlet 27, the coin C is converted to the standing posture and the space portion is formed. 30
It is possible to prevent the coin C from being caught in the coin inlet portion 27 by falling through the spiral surface portion 35.

Moreover, since the space 30 and the recess 29 are provided in common, the simplification can be achieved.

The coin hoisting device 21 can be used not only for conveying the coin C upward, but also for conveying the coin C downward. In this case, the coin C can slide down on the spiral surface portion 35. By rotating the spiral rotator 23 in correspondence with the downward conveying direction, the coin C can be reliably conveyed downward.
