DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transferring coins in a coin wrapping machine for transferring coins accumulated in an accumulation section to a packaging section.

[0002]

2. Description of the Related Art Conventionally, as a coin wrapping machine, there is one disclosed, for example, in Japanese Patent Laid-Open No. 2-72013. This means that the coins fed from the turntable are accumulated on an accumulation drum, a predetermined number of accumulated coins are transported to a delivery position, and a coin receiver arranged at a packaging position is moved to the delivery position. The coins are to be delivered at. Further, the coin receiver that has received the stacked coins is moved to a wrapping position in that state, and at this position, after the wrapping roller supports the circumferential surface of the stacked coin, the wrapping paper is wound around the circumferential surface of the stacked coin. To be packaged.

The coin receiver is supported by a supporting mechanism so as to be able to move up and down, and a coin receiving cam provided at a position in contact with the supporting mechanism is driven at a predetermined speed to rotate. . In other words, the coin receiving cam that comes into contact has a shape such that the coin receiver moves in the range from the packaging position to the delivery position, and at the delivery position located above, the radius dimension of the coin receiving cam is large, Conversely, at the packaging position, the radius dimension is reduced.

[0004]

By the way, in the conventional coin wrapping machine described above, in order to move the support mechanism for supporting the coin receiver at a set speed, a coin receiving cam which comes into contact with the mechanism is set. It is necessary to rotate at the specified speed. For this reason, the coin receiving cam is rotated at a stable set rotation speed by using a plurality of gears for the drive mechanism for driving the coin receiving cam.

On the other hand, in order to rotate the meshing gear, it is necessary to provide a slight gap (backlash) between the meshing tooth of one gear and the meshing tooth of the other gear. In the conventional transfer device, when moving up to the coin receiving position to receive the coins accumulated on the accumulation drum, the coin receiving cam contacting the support member has a shape in which the radial dimension gradually increases. The gears of the drive mechanism for rotating and driving the coin receiving cam transmit the drive by rotating the gear teeth of the driven gear in the direction of rotation of the driven gear against the counter-rotation surface of the driven gear teeth. Has become.

Further, when the coin receiver supporting the stacked coins at the upper coin transfer position is lowered to the lower wrapping position, the shape of the coin receiver cam is such that its radial dimension is gradually reduced. Therefore, the coin receiving cam which comes into contact with the support mechanism is subjected to a load in the rotation direction by the support mechanism, and the rotation direction surface of the teeth of the driven gear of the drive mechanism portion is opposed to the teeth of the drive gear. Vibration at this time is transmitted from the drive mechanism to the coin receiver via the coin receiver cam and the support mechanism, and the coins above the stacked coins placed on the coin receiver dance. However, there is a fear that the state of accumulation of the accumulated coins may be destroyed.

Next, with reference to FIG. 2, FIG. 3, FIG. 5, and FIG. 6, the operation of moving the coin stack according to one embodiment of the present invention will be described in detail. First, the positions of the coin receiving cam 35 and the caulking cam 36 shown in FIG. 2, FIG. 3, and FIG. 5 (1) are the driving start positions. At this driving start position, the coin receiver 19 is at the standby position. Note that this drive start position is X. FIG.
(1) From the drive start position X shown in FIG.
When the coin receiving cam 35 is rotated counterclockwise in FIG. 5, the coin receiving cam 35 is supported by the roller 27 contacting the coin receiving cam 35 until the point A shown in FIG. The member 24 is rotated clockwise in FIG. 2, the coin receiver 19 is raised along the bar 21, and the coin receiver 19 reaches the stacking coin transfer position.

Here, the driving motor 3
When the gear 1 is driven, at a position where the gears of the drive mechanism 37 mesh with each other, the rotation direction surface of the teeth of the drive gear comes into contact with the surface opposite to the rotation direction of the driven gear teeth.
The drive is transmitted to the coin receiving cam 35, and the coin receiving cam 35 is rotated counterclockwise.

The caulking claws 52 and 53 at the point A are
Since the roller 38 does not move in the radial direction, as shown in FIG. 6, the cam curve of the caulking cam 36 indicates a line in a standby state, and the caulking claws 52 and 53 are not driven. As shown in FIG. 6, when the rotation of the coin receiving cam 35 passes through the point A, the coin receiver 19 enters a standby state at the transfer position,
When the shutter 8 is opened at the point C, the coin receiver 19 receives the accumulated coins. Further, the rotation of the coin receiving cam 35 is D
After passing the point, the coin receiver 19 supporting the accumulated coins,
It is lowered from the delivery position.

Here, according to the present embodiment, during the standby state of the coin receiver 19 until the rotation of the coin receiving cam 35 passes through the point A and the shutter 8 is opened at the point C,
The caulking cam 36 is a descending cam portion whose radial dimension at the contact position of the roller 38 is gradually reduced. Therefore, the caulking cam 36 urges the arms 48 and 49 in directions approaching each other. A load for rotating in the same direction (counterclockwise in FIG. 5) as the direction of rotation by the drive motor 31 is applied by the biasing force of the spring, and the load applied to the caulking cam 36 is transmitted to the camshaft 29.

That is, the coin receiver 19 is moved to the coin receiving cam 35.
Is moved up from the standby position by the up cam
Coin receiving until it is lowered to the packaging position by the descending cam part
Stay at the transfer position due to the top dead center area of the cam 35
After being moved to the delivery position
By the time the coin is received, the cam
The same direction as the rotation direction by the drive motor 31 on the shaft 29
As a result, the driven gear 30 fixed to the camshaft 29 is rotated by the amount of backlash with the drive gear 34, and the rotation direction surface of the driven gear 30 is rotated counter to the anti-rotation of the teeth of the drive gear 34. It comes into contact with the directional surface.

That is, conventionally, when the coin receiver 19 that has received the accumulated coins passes the point D and starts descending, the weight of the accumulated coins is increased via the coin receiver 19, the support member 24, and the coin receiving cam 35. Since it is transmitted to the camshaft 29 and acts as a load for rotating the camshaft 29 counterclockwise in FIG. 2, the camshaft 29 is counterclockwise in FIG. 2 by the backlash between the driven gear 30 and the driving gear 34. After being rotated around at once, the rotation direction surfaces of the teeth of the driven gear 30 and the anti-rotation direction surfaces of the teeth of the drive gear 34 contact each other, and the impact generated at this time causes the accumulated coins delivered to the coin receiver 19 to move. Although there is a possibility that the accumulated state of the accumulated coins may be disrupted due to vibrations generated above, in the present embodiment, as described above, the coin receiver 19 attaches the camshaft 29 to the camshaft 29 before the point C where the accumulated coins are received, as described above. By applying a load in a counterclockwise direction, the rotational direction surface of the teeth of the driven gear 30 and the anti-rotational surface of the teeth of the drive gear 34 are brought into contact in advance, thereby avoiding the conventional vibrations on the accumulated coins. can do.

When the rotation of the coin receiving cam 35 has passed the point D, the coin receiver 19 drops to the point E, that is, the wrapping position while supporting the stacked coins, and the wrapping rollers 10, 1
Reference numerals 1 and 12 indicate 3 by a packaging roller moving cam (not shown).
The stacking coins are sandwiched from the direction, and the wrapping paper 13 is wrapped around the stacking coins (in FIG. 6, the cam diagram after the point E is omitted).

As described above, according to the stacked coin transfer device in the coin wrapping machine of the present embodiment, the load is applied to the camshaft 29 in the counterclockwise direction in FIG. By contacting the rotational direction surface of the tooth of the driven gear 30 with the anti-rotational surface of the tooth of the driving gear 34, the driven gear 30 is backed up when the coin receiver 19 receives the accumulated coin, as in the related art. The rotation of the driven gear 30 at a stroke by the amount of the rush and the prevention of the vibration of the coin receiver 19 caused by the contact of the rotating surface of the driven gear 30 with the anti-rotating surface of the driving gear 34 are reliably prevented. It is possible to prevent the accumulated coins transferred to the coin receiver 19 from jumping due to vibration, and to transfer the accumulated coins to the packaging position while maintaining a good accumulation state.

In this embodiment, the coin receiver 1 starts at point A.
During the time point C where the coin 9 receives the coins, the camshaft 29
The caulking cam 36 is used as a means for applying a load in the same direction as the rotation direction by the drive motor 31. However, the present invention is not limited to this, and other cams that enter the standby state at points A to C described above. May be used.

[0043]

As described above, according to the integrated coin transfer device in the coin wrapping machine of the present invention, the following effects can be obtained. According to the first aspect, before the coin receiver receives the accumulated coins, a load is applied to the camshaft by the control cam in the same direction as the rotation direction by the drive motor to drive the camshaft in advance in the rotational direction surface of the teeth of the driven gear. By keeping the gear teeth in contact with the anti-rotational surfaces, as in the conventional case, when the coin receiver receives the accumulated coins, the driven gear rotates at a stroke by the amount of the backlash, and the teeth of the driven gear are rotated. The rotation direction surface of the drive gear contacts the anti-rotation direction surface of the teeth of the drive gear to reliably prevent the vibration of the coin receiver, which prevents the accumulated coins transferred to the coin receiver from jumping. Then, it is possible to transfer the accumulated coins while maintaining a good accumulation state.

According to the second aspect of the present invention, there is provided a caulking claw.
