Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a coin stacking device that is applied to a coin wrapping machine that wraps stacked coins into a bar shape.

``Prior art'' As a conventional example of the above-mentioned coin accumulating device,
-There is one described in Publication No. 208329. This device rotates synchronously a pair of stacking drums each having a spiral protrusion (support shelf) formed on the outer periphery, and a coin support portion (the outer periphery of a coin is placed on a part of the spiral protrusion) on the protrusion. A predetermined number of coins are stacked between the stacking drums while moving the coins downward.

FIG. 3 shows the structure of the stacking drum section in the above-mentioned prior art.

Reference numeral 1 denotes a coin conveyance path, 2 a conveyor belt running along the coin conveyance path 1, and the coins C conveyed by these are transferred by guide rollers 3 between a regulation plate 4 and an accumulation guide plate 5. A predetermined number of coins are stacked with the peripheral edge supported by a support shelf 7 on the outer periphery of the stacking drum. Further, a shutter 8 is provided below the coin accumulation section 6 so as to be retractable.
A predetermined number of coins stacked are supported at a lower position of the stacking section 6 instead of the support shelf 7, and are sent out to a coin wrapping section (not shown) below by retreating from the illustrated position. There is.

"Problem to be Solved by the Invention" By the way, the width dimension of the above-mentioned stacking section 6, that is, the distance _D1 between the regulating plate 4 and the stacking guide plate 5, is the same as the width of the coins placed horizontally on the shutter 8. Since it is set to be slightly larger than the diameter of C,
In the case of an oblique posture supported by the spiral support shelf 7, it is inevitable that a gap will be created between the coin C and the regulation plate 4 or the accumulation guide plate 5. In addition, especially in the initial stage of accumulation with a small number of sheets, the support shelf 7
The attitude of the coin C, which is supported in almost point contact by the support shelf 7, is extremely unstable, and as shown in the coin near the top of Fig. 3, the inclination is smaller than that of the support shelf 7, and the attitude is almost horizontal. There are cases.

If the coin is in a nearly horizontal position, that is, the rear end along the coin feeding direction is at a height close to the front end, the front end of the subsequently fed coin will collide with the coin, resulting in coin jams. This may cause problems.

This idea was proposed in view of the above circumstances.
The purpose of this is to maintain a constant posture of the stacked coins and prevent coin jams from occurring.

"Means for Solving the Problem" In order to achieve the above object, the present invention provides a coin transport path that transports coins one by one along the surface direction and sends them out in a horizontal state, and a coin transport path on both sides of the tip of the coin transport path. a pair of accumulating drums that are provided in the stacking drum and rotate synchronously in opposite directions; and a support shelf that is provided around the accumulating drum in a spiral shape with equal pitches and opposite winding directions to respectively support the peripheral edges of the coins. a regulating plate provided parallel to the stacking drum on the front side in the coin conveying direction and guiding the side of the stacked coins; and a regulating plate provided parallel to the stacking drum at a position opposite to the regulating plate to guide the side of the stacked coins. In the coin stacking device, the regulation plate has a distance from the stacking guide plate that is approximately equal to the outer diameter of the coins, and a height dimension that is large enough to accommodate a predetermined number of coins to be stacked. A lower part set slightly larger than the height dimension is continuously formed in the upper part of the lower part, and the interval between the collecting guide plate and the collecting drum is horizontal to the coins supported in an inclined manner on the support shelf of the collecting drum. a wide part that is approximately equal to the length of the direction component and whose height direction is set to a position above the coin transport path; The bending portion is formed so as to guide the rear end of the coin to be lowered by contacting the leading end of the coin sent out from the coin conveyance path.

"Operation" With the above configuration, when the tip of the coin sent out from the coin conveyance path comes into contact with the bending part, the bending part is bent toward the upstream side of the coin conveyance path, so that when the tip of the coin is sent out from the coin conveyance path, The side of the coin contacts the bent portion first to restrict its movement, and in this state, the lower side of the tip of the coin moves toward the bent portion, thereby lowering the rear end of the coin. Therefore, the rear end of the coin will not collide with the leading end of the next coin to be sent out.

In addition, since the distance between the wide portion having the bent portion at the top and the accumulation guide plate is approximately equal to the length of the horizontal component of the coins tiltedly supported on the support shelves of the accumulation drum, the wide portion Coins stacked between the stacking guide plate and the stacking guide plate do not shift in the radial direction.

"Embodiment" Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the figure, parts common to the conventional example are given the same reference numerals to simplify the explanation.

Reference numerals 20A and 20B denote stacking drums, each of which has a spiral support shelf 7 formed on its outer periphery. These support shelves 7 have the same amount of radially outward protrusion of the stacking drums 20A, 20B and the same helical pitch, and the helical directions are set to be opposite to each other. The stacking drums 20A and 20B are rotatably supported around shafts 21A and 21B, respectively, and are rotated at a constant speed in opposite directions by a driving mechanism (not shown) such as a stepping motor. and is supported by arms 23A, 23B which are swingable about shafts 22A, 22B. Further, the arms 23A and 23B are connected via a link 24 and pins 25A and 25B so that they can operate in conjunction with each other. Further, one arm 9 is provided with a cam follower 26, and by pressing the cam follower 26 against a denomination setting cam (not shown), the arms 23A, 23B swing in opposite directions to each other, and the accumulated drum 20A, 20
The mutual spacing between B and the like is adjusted according to the denomination (coin diameter). Reference numeral 27 denotes gears that rotate together with the collecting drums 20A, 20B, and mesh with each other to rotate both the collecting drums 20A, 20B in opposite directions.

Furthermore, regulation plates 4A and 4B are attached to the tips of the arms 23A and 23B, respectively.
These regulating plates 4A, 4B are designed to form a storage space for the accumulated coins between the accumulation guide plates 5, as in the case of the example shown in FIG. The regulation plates 4A, 4
B is a plate material having a dogleg-shaped cross section as shown in FIG. 1, and its base end is connected to the arm 2.
It is fixed to the tips of 3A and 23B by bolts 28, and the tips thereof are located between the stacking drums 20A and 20B in FIG. Further, the regulation plates 4A, 4B are
As shown in the figure, by setting the width dimension of the upper part to be large and the width dimension of the lower part to be small, the distance between the stacking guide plate 5 and the lower part is large (as in the example in Fig. 3, it is slightly smaller than the coin diameter). The upper part has _a smaller size ( _D2 ) which can accommodate coins C inclined at an angle θ approximately equal to that of the accumulation shelf 7,
If the above D ₁ is approximately equal to the outer diameter of the coin, then D ₂ =
D ₁ cos θ), and the height dimension of the lower part where the interval is larger is set to be slightly larger than the height (thickness) dimension of the coins when the predetermined number of coins to be stacked is stacked by the stacking device. . The wide portion 4a at the top of the regulating plates 4A, 4B extends to a position above the lower surface of the conveyor belt 2 (the upper surface of the coins to be conveyed), and forms a part of the cylindrical surface on the upstream side of the coin conveying path 1. A bent portion 4b is formed that is curved toward. Note that the accumulation drums 20A, 20B and the regulating plates 4A, 4B are both connected to the arm 23.
Since it is supported by A and 23B, it can be moved by operating the cam follower 26 with a denomination setting cam (not shown) and set in a positional relationship corresponding to the coin diameter of each denomination. ing.

The operation of the integrated device configured as above will be explained.

First, operate the denomination setting cam (not shown) to set the stacking drums 20A, 20B and the regulating plates 4A, 4B.
is moved to a predetermined positional relationship according to the denomination. Next, the coin conveying path 1 and the conveying belt 2 are operated (note that the coin sorting means such as a rotating disk provided further upstream of these also operates as a matter of course).
When the coin C is moved to the left in FIG.
It comes into contact with the bent portions 4b of A and 4B. Then, since the bent portion 4b is bent toward the upstream side of the coin conveyance path 1, the upper side of the tip of the coin C comes into contact with the bent portion 4b first, and movement is restricted, and in this state, the coin C is The lower side of the tip moves toward the bent portion 4b, and thereby the rear end of the coin C lowers. In addition, the coin peripheral portion is stored in the accumulating drum 20.
It is supported on the support shelves 7 of A and 20B. Further, the coins C supported on the support shelf 7 are in an inclined state along the inclination of the support shelf 7, but the distance _D2 between the regulating plates 4A, 4B and the accumulation guide plate 5 is approximately equal to this inclined state. Since the coins match the horizontal length of the coins, they are neatly stacked in the coin stacking section 6 between the regulating plates 4A, 4B and the stacking guide plate 5 in an inclined state. As the coins C are fed out one after another, the stacking drums 20A and 20B are rotated so that the spiral of the support shelf 7 advances by a dimension corresponding to the thickness of the coins C, thereby raising the top surface of the uppermost coin to a certain height. A predetermined number of coins are accumulated while maintaining the height (slightly lower than the coins sent out). The coins C thus accumulated move downward as the spiral progresses, and are accumulated on the shutter 8 in a horizontal position. At a position below the wide portion 4a, the width dimension _D1 of the stacking section 6 is made approximately equal to the coin diameter, so the coins C are stacked in a horizontal position. Further, the predetermined number of coins that have been stacked are sent to a packaging device (not shown) located below the stacking device, and packaged by this packaging device.

Note that although the bent portion in the above embodiment has a cylindrical curved shape, it can also be configured with a plurality of discontinuous inclined surfaces and the tip of the coin can be brought into contact with the bent portion in the same way. The rear end of the coin can be lowered.

"Effects of the Invention" As is clear from the above explanation, according to the present invention, the bent part bent toward the upstream side of the coin conveyance path is provided at the upper part of the wide part of the regulating plate, so that the coin When the tip of the coin sent out from the conveyance path comes into contact with the bending part, the upper side of the coin tip first contacts the bending part and movement is restricted, and in this state, the lower side of the coin tip moves toward the bending part. , which causes the rear end of the coin to drop. Therefore, it is possible to prevent the rear end of the coin from colliding with the leading end of the next coin to be sent out.

In addition, since the distance between the wide part and the accumulating guide plate is approximately equal to the length of the horizontal component of the coins supported in an inclined manner on the support shelf of the accumulating drum, the distance between the wide part and the accumulating guide plate The coins accumulated in the area will not shift in the radial direction. Therefore, the coins accumulated at the top, that is, the coins that tend to be in an unstable posture because there are few coins accumulated above themselves, are held within a gap that is approximately equal to the dimension in the inclined posture. It has the effect of being able to be stabilized and accumulated in an orderly manner.
