Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stacked coin delivery device for a coin wrapping machine.

[Prior art] In recent years, as a coin wrapping machine,
Coin wrapping machines such as those described in Publication No. 208329 are widely used. This method does not use a stacking cylinder, but instead stacks coins while supporting them vertically using a spiral protrusion provided on the outer periphery of a pair of stacking drums, and by rotating the pair of stacking drums. Then, the position of the stacked coins is gradually lowered until a desired number of coins are stacked. The stacked coins are delivered to and wrapped by a wrapping mechanism, which is constructed around three wrapping rollers and arranged below the stacking drum.

In this case, the stacked coins are gradually lowered and stacked by the thickness of one coin, and after stacking the number of coins to be packaged, the stacking drum is continuously rotated to be placed below the stacking drum. It was lowered to the top of the shutter. This position serves as a delivery position where the product is delivered to the packaging mechanism below.

On the other hand, the packaging mechanism includes a coin receiver that receives the accumulated coins at the delivery position. An example of this coin receiver is described in Utility Model Publication No. 56-51444. This system uses a lever consisting of a top lever (front part on the driven side) and a shift arm (rear part on the driving side) to raise and lower a conveyor arm (transport rod) with a coin receiver (support rod) at its tip to collect coins. It is for handing over and receiving.

In this case, the top lever and the shift arm are connected at their ends so as to be bent into a dogleg shape, and are pulled in the direction of the straight line by the spring, and pressed in the direction of bending by the adjustment screw. has been done. Then, in the packaging position, the coin receiver is adjusted using the adjustment screw so that it is in the correct position. On the other hand, when the coin receiver is in the coin delivery position, the conveyor arm rises and is stopped by the upper regulating member, and at this time, the top lever bends against the biasing force of the spring. I was getting used to it. In this state, the coin receiver was accurately positioned at the coin delivery position, minimizing shock when the accumulated coins fell.

[Problems to be Solved by the Invention] According to the conventional coin wrapping machine described above, even if there are dimensional variations in members such as the conveyor arm, top lever, shift arm, etc., it is difficult to accept coins at the coin delivery position and the packaging position. It is possible to accurately position the

However, when the coin receiver is in the delivery position, the top lever is always bent and tensioned by a spring. Then,
When the shift arm moves downward toward the packaging position, the bent lever returns to its original straight state. In this case, since the accumulated coins were placed on the coin receiver and were in an unstable state with no other support, the accumulated coins sometimes collapsed during the process of returning the lever. Especially when it comes to small diameter coins, the stack of coins tends to collapse.

Furthermore, the time it takes for the stacked coins to descend from the delivery position to the packaging position is about 0.2 seconds, and the coin receiver drops instantly, which delays the return of the top lever and prevents higher speeds. This drawback could not be improved even if the force of the spring was strengthened.

This invention was made against this background, and it is possible to accurately adjust the position of the coin receiver, and to prevent the collected coins from collapsing even during high-speed processing. An object of the present invention is to provide a stacked coin delivery device in a coin wrapping machine.

[Means for Solving the Problems] In order to solve the above problems, the present invention includes: a shutter in which a predetermined number of coins are accumulated; and a plurality of shutters arranged around the accumulated coin packaging position below the shutter, a wrapping roller that wraps a wrapping paper around the accumulated coins guided to the position; a wrapping roller that is supported vertically and movably between the accumulated coin delivery position directly below the shutter and the accumulated coin packaging position; a coin receiver that receives the accumulated coins when the shutter opens and vertically descends to the accumulated coin packaging position; a conveyor arm provided with a bearing section that is guided so as to be movable in the vertical direction; a shift arm which has a horizontal shaft at a horizontal position, extends substantially in a straight line from the shaft toward the base end of the conveyor arm, and is supported by a cam so as to be swingable in the vertical direction about the shaft; , extends in a substantially straight line from a horizontal axis provided at the swinging tip of the shift arm toward the base end of the conveyor arm, and extends in a substantially straight line integrally with the shift arm, and extends vertically about the axis. It further includes a top lever that is swingably supported and can adjust a swing angle with respect to the shift arm, and by connecting the base end of the conveyor arm and the top lever, the coin receiver can be moved vertically. The coin wrapping machine is configured to move up and down in a vertical direction, and the top lever is supported to be swingable in a vertical plane about a horizontal rotation shaft provided at the swinging tip of the top lever, and is connected to the top lever. The adjustment plate has an adjustment plate that can adjust the swing angle, and the adjustment plate has a position approximately vertically above the rotation axis that is the center of swing of the adjustment plate when the shift arm swings upward in the vertical direction. The conveyor arm is characterized in that a roller that is engaged with and connected to the base end of the conveyor arm is supported at the position.

[Function] According to the above configuration, in order to adjust the accumulated coin delivery position, that is, the position of the coin receiver, first, by swinging the shift arm to the uppermost side, the coin receiver is moved via the top lever, adjustment plate, and roller. move it upwards. At this time, the top lever, which is integrated with the rotating lever, is rotated vertically to move the coin receiver to an appropriate position directly below the shutter.

The vertical adjustment movement amount of the coin receiver in adjusting the stacked coin delivery position is mainly determined by the vertical swing amount (adjustment of the adjustment angle Δθ) of the top lever that is integrated with the rotation lever. , the vertical height is adjustable.

On the other hand, the adjustment plate is temporarily fixed to the top lever in advance so that the roller is positioned substantially perpendicularly above the rotation axis. In this state, as described above, when the swing angle of the top lever with respect to the shift arm is adjusted, the adjustment plate also rotates through the adjustment angle Δθ, but the amount of movement is such that it has no effect on the vertical direction at all. .

Here, the distance between the rotation axis and the roller is R2, and the rotation angle of the roller from the vertical line is equal to the adjustment angle Δθ, so the vertical movement amount ΔD of the roller
is ΔD=R2 (1-cosΔθ), and if R2=30mm and Δθ=±2°, then ΔD=0.02mm, which is the amount of movement that can be said to have no effect at all.

Therefore, adjustment of the vertical height position of the coin receiver at the stacked coin delivery position is mainly done by:
It is determined by the vertical swing amount (adjustment angle based on the adjustment angle Δθ) of the top lever, which is integrated with a rotary lever supported by a shaft so as to be swingable in the vertical direction.

Next, in order to adjust the stacked coin packaging position,
Swing the shift arm to the lowest position. First, the height position of the coin receiver in the vertical direction is appropriate when the shift arm is rotated to the stacked coin wrapping position before adjusting the rotation of the top lever at the stacked coin delivery position. Assume that

In this case, as a result of the adjustment at the stacked coin delivery position, when the shift arm swings to the stacked coin wrapping position, the vertical height position of the roller changes from its initial appropriate position. That is, when the top lever is lowered, the height position of the roller becomes lower than the initial height position, and in the opposite case, it becomes higher. Therefore, the height position of the roller is
It would be better to adjust in the opposite direction.

In this accumulated coin wrapping position, the swing angle of the shift arm appears to be equal to the intersection angle of the straight line connecting the rotation axis of the adjustment plate and the roller with the vertical line, so The height position can be changed significantly by swinging the adjustment plate relative to the top lever, and the amount of displacement due to rotational adjustment of the top lever at the stacked coin delivery position is It is absorbed by the amount of displacement due to the rotational adjustment of the adjustment plate at the position.

As can be seen from the above, the positions of the delivery position and the packaging position of the accumulated coins can be adjusted independently, and therefore, the adjustment can be made easily.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the overall structure of a coin wrapping machine 1. FIG. In the figure, coins accumulated in a hopper 11 are sent to a rotary disk 13 by a supply conveyor 12, passed through a sorting passage 14, and are accumulated one by one between accumulation drums 15 and 16. That is,
Coins are stacked in stacking drums 15 and 16 and a regulating body (not shown)
They are accumulated one by one in the space formed by. Spiral projections 15a, 16a are formed on the outer peripheries of the collecting drums 15, 16, and coins are supported by these projections 15a, 16a. In this case, the accumulating drums 15, 16
rotates slightly each time a coin is stacked, lowering the coin by the thickness of the stacked coin. That is, the topmost coin is always located at the exit of the sorting passage 14.

The accumulated coins C gradually descend as the accumulating drums 15 and 16 rotate, and as shown in FIG.
It is transferred down to the position of the shutter 18 located at the bottom of the collecting drums 15, 16 (FIG. 6c).

In this way, when the accumulated coins C reach the top of the shutter 18, the shutter 18 is opened (FIG. 6d),
The coins are delivered to the coin receiver 31a that has risen from the packaging mechanism section.

In FIG. 1, reference numeral 19 is a denomination setting dial, which is a means for changing the width of the sorting passage 14 and the interval between the collecting drums 15 and 16 according to the denomination.

The packaging mechanism section is constructed around three packaging rollers 21 , 22 , 23 located below the stacking drums 15 , 16 . The accumulated coins are wrapped by The wrapped coins are discharged from the roll chute 27.

Next, FIGS. 2 and 3 are diagrams showing mechanisms related to the conveyor arm, with FIG. 2 being a side view and FIG. 3 being a plan view taken along the line - in FIG. 2. In these figures, a coin receiver 31a provided at the tip of a conveyor arm 31 is retractably arranged in the middle of the three packaging rollers 21, 22, 23.

The conveyor arm 31 is attached to a shaft 33 so as to be movable up and down by a pair of upper and lower bearings 32 attached to its base end. This bearing part 32
consists of three bearings 34a, 34b, and 34c arranged at equal intervals around the shaft 33.
3, the conveyor arm 31 is raised and lowered. The conveyor arm 31 also includes:
A mounting plate 35 is fixed, and this mounting plate 35 has
A pair of bearings 36a and 36b are attached to sandwich the shaft 37. Therefore, the horizontal movement of the conveyor arm 31 is regulated by the shaft 37, and it rotates about the shaft 33 as the shaft 37 moves.

The upper and lower ends of this shaft 33 are fixed to an upper connecting member 41 and a lower connecting member 42, respectively, and these connecting members 41 and 42 are rotatably supported by the shaft 33. Further, a roller 43 is attached to the end of the lower connecting member 41, and this roller 43
is driven in the horizontal direction by an arm (not shown), so that the conveyor arm 31 rotates around the shaft 33, and the coin receiver 31a provided at the tip of the conveyor arm 31 moves toward the packaging rollers 21, 2.
It has started to appear between February 2 and 23.

At the base end of the conveyor arm 31, a notch 45 is provided between the pair of bearings 32, 32, and a roller 84 on the top lever 81 side, which will be described later, is fitted into the notch 45. Note that this roller 84 is fixed to an adjustment plate 83 fixed to the tip of the top lever 81.

4 and 5 are diagrams showing the configuration of the shift arm 50 and top lever 81 for raising and lowering the conveyor arm 31, with FIG. 4 being a side view and FIG. 5 being a plan view.

A horizontal shaft 51 is provided at the base end of the shift arm 50.
However, a cam roller 52 is attached to the center portion, and as a cam 53 that contacts the cam roller 52 rotates, the shift arm 50 rotates in the vertical direction. This cam 53 is connected to the cam shaft 54
The camshaft 54 is rotated by a motor shaft 57 via a driven gear 55 and a driving gear 56.
a and is rotationally driven by a camshaft drive motor. Note that the shift arm 50 is urged downward by a spring (not shown) so as to be in constant contact with the cam 53.

A pulley 58 is also fixed to the motor shaft 57a and connected to an electromagnetic brake 60 via a belt 59. This electromagnetic brake 60 is for applying braking to the motor shaft 57a to hold the coin receiver 31a at that position when the coin receiver 31a comes to the accumulated coin delivery position.

A disk (not shown) is fixed to the camshaft 54. This disk has one slit in its circumferential direction. Therefore, by detecting this slit with a sensor, the rotation of the cam and its initial position can be detected.

Next, a pair of support levers 71 and 72 are attached to the shift arm 50 so as to sandwich it therebetween. That is, an L-shaped support lever 71 is attached to the lower part of FIG. 5 (front of FIG. 4), and the fifth
A longer T-shaped support lever 72 is fixed to the upper side of the figure (rear side in Figure 4). A shaft 73 is attached to the downwardly protruding portion of these support levers 71, 72, and a rotating lever 74 that rotates around this shaft 73 is attached to the support levers 71, 72.
It is attached in such a way that it is sandwiched between.

The rotating lever 74 is biased clockwise (upward) in FIG. 4 by springs 75 and 76 stretched between it and the shift arm 50, and an adjustment bolt fixed to the support lever 72 77 restricts upward movement.

The above-mentioned top lever 81 is fixed to this rotating lever 74. A shaft 82 is fixed to the tip of the top lever 81, and a triangular adjustment plate 83 is rotatably attached to the shaft 82. A roller 84 that engages with the notch 45 of the conveyor arm 31 is attached to the adjustment plate 83 . Further, a long hole 85 is formed in the adjustment plate 83, and a screw 86 fitted into the long hole 85 allows the adjustment plate 83 to be tightened to the top puller 81. Thereby, the position of the coin receiver 31a at the delivery position and the packaging position can be finely adjusted.

FIG. 7 is a side view for explaining position adjustment of the coin receiver at the stacked coin delivery position and the packaging position.

First, in order to adjust the stacked coin delivery position, the shift arm 50 is swung to the uppermost side (the upper position shown by the two-dot chain line in FIG. 7).

After this, the shift arm 50, the top lever 81 integrated with the rotation lever 74, and the top lever 81
When the coin receiver 31a, which has been moved vertically upward by the adjustment plate 83 temporarily fixed to the adjustment plate 83 and the roller 84 of the adjustment plate 83, comes into contact with the lower surface of the shutter 18, the adjustment bolt 77 is removed. The top lever 81, which is integrated with the rotating lever 74, is rotated vertically downward while the coin receiver 31a is rotated in the pushing direction.
If there is a large gap between
The top lever 81 integrated with the rotating lever 74 is rotated vertically upward and adjusted so that the coin receiver 31a is located directly below the shutter 18.

At this time, the amount of adjustment movement of the coin receiver 31a in the vertical direction is mainly determined by the amount of vertical swinging of the top lever 81, which is integrated with the rotating lever 74, which is supported by the shaft 73 so as to be swingable in the vertical direction.

That is, the distance between the shaft 73, which is the center of swing of the top lever 81 that is integrated with the rotary lever 74, and the rotation shaft 82 at the tip of the swing is R1, and the distance from the shaft 73 to the rotation shaft 8 is R1.
If the initial elevation angle when viewing 2 is θ1, and the adjustment angle from the elevation angle θ1 is Δθ, then the vertical movement amount D1 of the rotation shaft 82
becomes D1=R1(sinθ1−sin(θ1−Δθ)).

Here, if R1=94mm, θ1=20°, and Δθ=±1° or ±2°, when Δθ=+2°, D1=+3.1mm (vertically downward) When Δθ=+1°, D1 = +1.5mm (vertically downward) When Δθ = -1°, D1 = -1.5mm (vertically upward) When Δθ = -2°, D1 = -3.1mm (vertically upward), and there is a slight oscillation. The height can be adjusted vertically by moving.

On the other hand, the adjustment plate 83 has a roller 84 that is connected to the rotation shaft 82.
The top lever 81 is temporarily fixed in advance to the top lever 81 by a fixing screw 86 at a substantially central position of the elongated hole 85 so as to be located substantially vertically above the elongated hole 85 .

In this state, as mentioned above, the top lever 8
When the swing angle for the first shift arm 50 is adjusted, the adjustment plate 83 also rotates by the adjustment angle Δ.

Here, the distance between the rotating shaft 82 and the roller 84 is
R2, the rotation angle of the roller 84 from the vertical line is equal to the adjustment angle Δθ, so the vertical movement amount ΔD of the roller 84 is ΔD=R2 (1−cosΔθ), and R2=30 mm, If Δθ=±2°, ΔD=0.02mm, which is a movement amount that can be said to have no effect at all.

If the rotation angle θ2 of the roller 84 from the vertical line is maximized, that is, the adjustment plate 83 is
The vertical movement amount D2 of the roller 84 when it rotates from the center position of the hole 85 to both ends of the elongated hole 85 is D2 = R2 (1-cos θ2), and if θ2 = ±8°, then D2 = 0.3 mm. , this is an amount of movement that can be said to have no effect.

Therefore, adjustment of the vertical height position of the coin receiver 31a at the stacked coin delivery position is mainly performed by adjusting the vertical swing amount of the top lever 81, which is integrated with the rotary lever 74, which is supported by the shaft 73 so as to be swingable in the vertical direction. It can be understood that it is determined by

Next, in order to adjust the stacked coin packaging position,
Swing the shift arm 50 to the lowermost side (seventh
(lower position shown in solid line in the figure).

First, before adjusting the rotation of the top lever 81 in the stacked coin delivery position, the vertical height position of the coin receiver 31a when the shift arm 50 is rotated to the stacked coin packaging position is not appropriate. Assume that it is hot.

In this case, as a result of the adjustment at the stacked coin delivery position, when the shift arm 50 swings to the stacked coin packaging position, the vertical height position of the roller 84 will vary from its initial appropriate position.

That is, when the top lever 81 is lowered, the height position of the roller 84 becomes lower than the initial height position, and in the opposite case, it becomes higher.

Therefore, it is sufficient to adjust the height position of the roller 84 in the opposite direction.

By the way, in this accumulated coin packaging position,
The swing angle of the shift arm 50 appears to be equal to the intersection angle θ3 between the straight line connecting the rotation shaft 82 of the adjustment plate 83 and the roller 84 and a vertical line.

Therefore, the height position of the roller 84 at this time is changed as follows by swinging the adjustment plate 83 with respect to the top lever 81.

That is, the amount of change d1 in the height position of the roller 84 when the adjustment plate 83 is fixed to the top lever 81 at one end of the elongated hole 85 (A side in FIG. 7), B side in the diagram) to top lever 8
If the amount of change in the height position of the roller 84 is d2 when it is fixed at 1, then d1=R2(cosθ3−cos(θ3−θ2)) d2=R2(cosθ3−cos(θ3+θ2)).

Here, if R2 = 30mm, θ3 = 40°, θ2 = 8°, d1 = -2.5mm (vertically upward) d2 = +2.9mm (vertically downward), and the top lever at the above-mentioned stacked coin delivery position It will be understood that the amount of displacement due to the rotational adjustment of the adjustment plate 81 can be absorbed by the amount of displacement due to the rotational adjustment of the adjustment plate 83 at this stacked coin packaging position.

Therefore, the adjustment bolt 7 at the coin delivery position
After adjusting the position with 7, adjust the adjustment plate 8 at the packaging position.
By rotating 3 to adjust the height, both positions can be adjusted almost independently. Moreover, Topp Lever 81
does not return from the bent position,
There is no risk that the accumulated coins will collapse due to the return operation.

After such position adjustment, the actual coin wrapping operation can be performed.

FIG. 6 illustrates the coin delivery process in this embodiment.

In Figure a, the shutter 18 is located directly below the stacking drums 15 and 16 and is in a closed state. Further, the accumulated coins C are at a considerably high position, and the coin receiver 31a is at the initial position.

FIG. 1B shows a state in which the coin receiver 31a has risen to the delivery position and is on standby. At this time, the electromagnetic brake 60 is on.

In the figure c, the accumulating drums 15 and 16 rotate once,
The accumulated coins are shown falling onto the shutter 18. As a result, preparations for transferring the accumulated coins are completed, and at this point, the electromagnetic brake 60 is turned off.

Figure d shows a state in which the coin receiver 31a supports the accumulated coins C and lowers them to the packaging position. Packaging processing is executed in this state.

According to this embodiment, in such a stacked coin delivery process, the coin receiver 31a can be accurately positioned at the stacked coin delivery position and the packaging position.

[Effects of the Invention] As explained above, the present invention eliminates the return operation of the lever and allows the position of the coin receiver to be adjusted almost independently and accurately at the stacked coin delivery position and the packaging position. You can get the following effects.

(1) Since the positioning accuracy of the coin receiver at both of the above positions is high, the coin delivery process can be performed smoothly.

(2) Since there is no return action of the lever, there is no need to destroy the accumulated coins. This is particularly effective for small diameter coins.

(3) Since the time required for the return operation of the lever is eliminated, it is possible to speed up the processing of transferring accumulated coins.
