Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a coin stacking section for stacking a predetermined number of coins in a coin packaging machine.

(Prior art) Conventional coin packaging machines of this type include, for example, the
- As disclosed in Publication No. 34048, etc., a coin supply section having a coin feeding means, a counting means, etc., and a coin accumulation section that aligns and stacks a predetermined number of coins sent from the coin supply section; It is equipped with a coin wrapping section located below the stacking section for wrapping the stacked coins with a packaging sheet, and drive and control means for these, so that coins are automatically stacked and wrapped.

The coin stacking section of this coin packaging machine is configured to stack coins therein using a cylindrical member (coin aligning tube) having a diameter corresponding to the coins.
In the structure shown in the above publication, in order to be applied to coins of multiple denominations of different sizes, the coin aligning tube is composed of a large number of divided pieces that partially overlap each other, and these divided pieces are interlocked. By providing a mechanism that operates inward and outward in the radial direction, a mechanism that drives this in response to denomination setting operations, etc., the coin alignment tube can be expanded and contracted.

Further, in such a coin stacking section, it is required to prevent the coins from standing up in the coin alignment cylinder so that the coins can be correctly stacked in an inverted state. As a structure for this purpose, for example, as shown in Japanese Patent Publication No. 42-902, the coin aligning tube is supported so as to be able to swing upward, downward, leftward, rightward, etc., and the above-mentioned coin aligning tube is supported in accordance with the rotation of a cam driven by a drive device. A device equipped with an actuation mechanism that swings the cylinder is known.

However, according to this structure, in addition to the members constituting the coin alignment tube, a mechanism for swingably supporting the coin alignment tube and an operating mechanism are required, and the structure of these mechanisms becomes complicated. Furthermore, if the coin aligning tube is made expandable and retractable with the structure described above, the structure of the coin aligning tube itself will be complicated, so if this is combined with the mechanism that adds the above-mentioned rocking motion, the entire coin stacking section will become very large. However, the structure becomes complicated, leading to problems such as deterioration of manufacturability and reliability, and increase in costs.

(Object of the Invention) In view of the above-mentioned circumstances, the present invention provides a stacking section structure of a coin packaging machine that can satisfactorily exhibit its function as a coin stacking section despite having a relatively simple structure.

(Structure of the Invention) The present invention provides a coin wrapping machine that stacks a predetermined number of coins and wraps the stacked coins with a packaging sheet, which is hung between a pair of main rollers and a guide roller that are arranged in parallel at a predetermined interval. A coin storage device comprising a belt having a predetermined vertical width, the belt being bent concavely from between the pair of main rollers, and a predetermined number of coins sent from a coin supplying means being stacked and stored by the concave portion of the belt. A back-up roller is arranged on the back side of the belt in the area where the coin storage chamber is formed, so as to maintain the shape of the belt in this area into a substantially true cylindrical shape with a partially cut out part. The belt is equipped with a drive device that rotates the main roller and drives the belt when the main roller is fed.

According to this configuration, when coins are stacked, the coin storage chamber made of the concave curved portion of the belt is maintained in a substantially true cylindrical shape with a partially cut out portion by the back-up roller, and the belt constituting the peripheral wall portion is By inserting coins while being driven, the coins are accumulated in the coin storage chamber, and rotational force is applied to the coins to prevent the coins from standing up.

Furthermore, if the positions of at least one of the guide roller and the backup roller are adjustable by a position adjustment mechanism, the coin storage chamber formed by the belt can be expanded and contracted by adjusting the positions thereof, and the coin storage chamber made of the belt can be expanded and contracted. The diameter of the coin storage chamber can be easily adjusted according to the denomination of the coin.

(Example) FIG. 1 shows a schematic structure of the entire internal mechanism of a coin packaging machine equipped with an integrated packaging device of the present invention. In this figure, a hopper 1 is provided at the top of the coin wrapping machine, and the coins put into the hopper 1 are sent to a rotary disk 3 via a belt conveyor 2.
Due to the centrifugal force of the rotary disk 3, the coins are sent out from a predetermined location on the periphery of the rotary disk 3 to the coin passage 4. Then, the coins are sent out one by one through the coin passage 4 to a chute 6 by a delivery belt 5 provided opposite to the coin passage 4, and by a counting mechanism (not shown) provided for the coin passage 4. When a predetermined number of coins have been counted, the feeding of coins is interrupted. The coins sent out from the coin passage 4 are supplied to a coin accumulating section 7 having a structure to be described in detail later through the chute 6. In this way, a coin supply section is configured.

A coin wrapping section 8 is arranged below the coin stacking section 7. This coin packaging section 8 wraps the stacked coins processed from the coin stacking section 7 using a coin support mechanism that can be raised and lowered, with a packaging sheet 9 supplied from a packaging sheet supply section. Although illustration of the specific structure is omitted, for example, as is conventionally known, three rollers that rotate synchronously are used, and while the packaging sheet 9 is introduced with the accumulated coins positioned between them, the rollers are By rotating the packaging sheet 9, the packaging sheet 9 is wrapped around the accumulated coins, and the upper and lower sides of the packaging sheet are further caulked with caulking claws. Further, the wrapped coins are sent out to the wrapped coin outlet via a lead-out passage (not shown).

FIG. 6 shows a position adjustment mechanism for the guide roller 13, and FIGS. 7 and 8 show a position adjustment mechanism for the backup roller 20. As shown in these figures, the guide roller 13 and the backup roller 20 are movable in conjunction with the rotation of an operating rod 40, and the operating rod 40 has a denomination setting dial (not shown). The dial is connected to and rotates as the dial is operated according to the denomination of the coin. A guide roller 13 and a back-up roller 2 are connected to the rotation of the operating rod 40.
0, the coin storage chamber 16 made up of the concave portion of the belt expands and contracts. In other words, the diameter of the coin storage chamber 16 is adjusted according to the diameter of the coin, which varies depending on the denomination.

To specifically explain these position adjustment mechanisms,
The position adjustment mechanism for the guide roller 13 shown in FIG.
One end side roll portion 44a is biased by a spring 43.
The lever 44 is in contact with the cam 41, and the tip roll portion 47a is pivotable about the fulcrum shaft 45, and is biased by a spring 46 so that the tip roll portion 47a is in contact with the lever 44.
a movable block 47 that abuts the other end 44b;
A guide roller support bracket 48 is attached to the movable block 47, and the guide roller 13 is rotatably attached to this bracket 48. When the cam 41 is rotated by the denomination setting operation, the lever 44 and movable block 47 swing, and the guide roller 13 moves in an arcuate direction about the fulcrum shaft 45. Accordingly, the coin storage chamber 16 expands and contracts to obtain a diameter that corresponds to the denomination of the coin.

The position adjustment mechanism of the backup roller 20 shown in FIGS. 7 and 8 includes a movable frame 52 whose one end is rotatably attached to the upper and lower support frames 17 and 18 via a shaft 51, and The movable frame 52 is attached to the end 47b of the movable block 47.

8 and a shaft 55 attached to the movable frame 52; ing.
Then, the back-up roller 20 moves in conjunction with the movement of the guide roller 13 by the swinging of the movable block 47 in response to the denomination setting operation, that is, the rotation of the movable frame 52 in conjunction with the movable block 47. As each of the links 56 to 58 is displaced in accordance with this, each of the backup rollers 20 is moved in response to the expansion and contraction of the coin storage chamber 16 during the denomination setting operation.

As shown in FIG. 9, the shutter 21 constituting the bottom of the coin storage chamber 16 includes a pair of shutter plates 21a, 21b that are attached to shutter receiving plates 61a, 61b and interlock with each other via a link 62.
It is biased toward the closed state by a spring 63, and is opened at a predetermined time by a shutter drive solenoid 64 via a link 65 and an arm 66.

The operation of the apparatus of this embodiment as described above will be explained next.

When a predetermined number of coins are sent from the coin supply section to the coin storage chamber 16 of the coin accumulation section 7 and accumulated, first, the clutch 34 in the drive device 30 is turned on, and the coins are loaded into the coin storage chamber 16. On the other hand, by driving the main roller 12 located on the rear side in the belt movement direction, the concave portion of the belt between the two main rollers 11 and 12 is pressed against the back up roller 20, and the coin storage chamber 16 is opened to a predetermined gap. A cylindrical state is ensured. Then, the clutch 33 is also turned on, and both main rollers 11 and 12 are driven to rotate synchronously at a constant speed. In this case, the guide roller 13
By adjusting the position of the back-up roller 20, the coin storage chamber 16 has a diameter that allows a certain minute gap between its inner surface and the coins to be processed.

In this way, as shown in FIGS. 10 and 11, the belt 15 forming the peripheral wall of the coin storage chamber 16 is
A predetermined number of coins 100 are sequentially thrown into the coin storage chamber 16 from above while being driven to rotate (arrow b) as the main rollers 11 and 12 rotate (arrow a). At this time, 10 coins were inserted.
When the coin 100 stands up and leans against the belt 15 on the peripheral wall of the coin storage chamber 16, a rotational force is applied from the belt 15 to the coin 100, and this rotational force causes the coin to fall down. Therefore, the coins 100 are reliably prevented from standing up, and the coins 100 are properly laid down and stacked in an aligned state, and a good coin accumulation effect can be obtained despite the relatively simple structure.

When this accumulation operation is finished, the main rollers 11 and 12
After the drive of the shutter 21 is stopped, the shutter 21 is opened, and the accumulated coins are supported by a support mechanism (not shown) that can be raised and lowered, and transferred to the packaging section 8, where a packaging operation is performed.

Furthermore, in the stacking section structure of the present invention, the numbers of the guide rollers 13 and 14 and the backup rollers 20 may be changed as appropriate. The driving device and the like are not limited to the above embodiments, and may be modified in design without departing from the gist of the present invention.

(Effects of the Invention) As described above, in the stacking section structure of the coin packaging machine of the present invention, the belt that is stretched around a pair of main rollers and a guide roller is concavely bent between the two main rollers, and this concave portion allows coins to be collected. A back-up roller is arranged on the back side of the coin storage chamber for accumulating coins, and a back-up roller is arranged on the back side of the chamber so as to maintain the shape of this part of the belt into a substantially true cylindrical shape with a partial cutout. Since a drive device is provided that rotates the main roller and drives the belt when the coins are fed in, the rotational force applied by driving the belt prevents the coins from standing up and places a predetermined number of coins in the correct lying position. The coins are stacked on top of each other and function well as a coin accumulator. Furthermore, the belt forms the peripheral wall of the coin storage chamber for stacking, and also serves as part of the operating mechanism that applies rotational force to the coins to prevent them from standing up, so the structure of the stacking section is simplified. be converted into

In addition, since the peripheral wall of the coin storage chamber is made of a flexible belt, it is possible to easily expand and contract the coin storage chamber, and a mechanism for adjusting the diameter of the coin storage chamber according to the coin is incorporated. In this case, the structure can also be simplified.
