Description

[Detailed description of the invention] This invention is based on a coin packaging machine that can perform the work of counting and taking out coins and the work of wrapping a predetermined number of coins in paper rolls. It is related to the device.

In conventional coin packaging machines of this kind, the operation of dials for setting the coin count and the number of packages to be wrapped and the operation of chute switching were performed separately, and therefore confusion often occurred due to erroneous operation.

Normally, when counting coins, they are counted in units of 500 to 50 coins, and the counted coins are packed in bags, but since the coins are wrapped in paper, they are counted in units of 20 to 5@. It is counted.

Generally, in this type of coin wrapping machine, the outlet for taking out the coins counted for bagging and the place for collecting the counted coins for packaging are different, but the counting is done in a common part.

Therefore, even though the dial is set to count 500 to 500 coins, if the switching chute, which is operated separately, is connected to the coin collecting cylinder for packaging, it will happen immediately after activation. Coins that are counted and supplied at extremely high speed overflow from the coin stacking tube, which can only hold 20 to 50 coins, and the situation becomes uncontrollable.

Also, if you count in units of 500 to 5,000 coins and when you try to take out the coins, if you accidentally set the dial to the packaging number setting area, the situation like the overflow of coins as described above will not occur. For example, if only two enemy coins were placed in a bag that could hold 5,000 coins, the machine would stop.

In order to eliminate this inconvenience, regardless of the dial setting, when bagging and unloading, when a bag is placed on the coin bagging nozzle, a switch installed near the coin bagging nozzle will automatically operate. A coin ejection path device has been developed in which the chute can be switched in the direction of the coin bagging nozzle, but the structure is complicated and smooth operation cannot be achieved unless it is assembled with a high degree of precision. There are some drawbacks.

Based on the above-mentioned viewpoints, this invention aims to provide a chute switching device for a coin wrapping machine that has an extremely simple mechanism and completely eliminates the above-mentioned difficulties. The feature is that the chute is switched in conjunction with the dial.

Next, an embodiment of this invention will be described with reference to the drawings.

Fig. 1 is a partially cutaway plan view of the device of this invention, Fig. 2 is a plan view of the dials for setting the coin count and number of packages, and Fig. 3 is a perspective view of the main parts of the chute. Shown in the figure.

FIG. 4 shows a longitudinal sectional side view of the coin accumulating tube in a state where the chute is connected to the coin accumulating tube, and FIG. 5 shows a front view of the state shown in FIG. 4.

Coins 2 flowing out from a hopper (not shown) are fed horizontally in series by an endless belt 3 into the coin passage indicated by reference numeral 1 in FIG.

Coins traveling through the coin path 1 come into contact with a star wheel 4 at the end of the coin path and are counted.

The star wheel 4 counts the passage of five coins per revolution in this embodiment.

Furthermore, this star wheel 4 forms part of a control mechanism that stops the pulley 6 that moves the endless belt 3 when the number set by the dial 5 is counted.

The dial 5 is used to set the coin count for bagging and packaging, and the value for bagging is 500.100012000.25, as shown in the side entry in Figure 2.
There is a scale 7 that sets 00.4000.500 degrees, and a scale 8 that sets 20.25.4oX5m as numerical values for packaging.

The dial 5 has a scale 7 or 8 on the device frame 9.
The number of rotations of the star wheel 4 until the pulley 6 stops is determined by matching with an index 10 provided on the side, and has an electrical signal extraction mechanism (not shown).

On the other hand, a cam 12 is fixed to the rotating shaft 11 of the dial 5.

The cam 12 has two cam surfaces 12A and 12B, and when the scale 7 is in the indicated range by the index 10, the cam surface 12A is attached to a lever 14 having a cam follower 13, and a shaft 15 serving as a fulcrum.
Allow horizontal rotation in the counterclockwise direction around (the position shown in the imaginary line in Figure 1).

Further, the cam surface 12B has a lever 14 having a cam follower 13.
is allowed to horizontally rotate in a clockwise direction, and is placed in the state shown by the solid line in FIG.

A long hole 14a is provided at the tip of the lever 14, and a pin 17 on the chute 16 side is fitted into this long hole.

The chute 16 is the coin bagging chute 1 shown in FIG.
6A and the coin wrapping shoe 16B are integrally connected by a member 19 through which a horizontal shaft 18 is inserted.

The shaft 18 is horizontally orthogonal to the coin passage 1 immediately below the tip of the coin passage 1, as shown in FIGS.
It is supported by the frame 9 so as to be able to freely slide in the axial direction.

A roller 20 is attached to the back surface of the member 19.

This roller 20 is connected to a guide groove 21 fixed to the frame 9 side.
It rolls inside and guides the chute 16.

The guide groove 21 is formed by a downward surface of the frame 9 and a bracket 22 fixed thereto.

The member 19 is stopped from the shaft 18 by stoppers 23 attached to both ends of the shaft 18.

The chute 16, which is displaced left and right by the horizontal swing of the lever 14 as described above, is in a state where the cam follower 13 is in contact with the cam surface 12B of the cam 12, that is, the scale 8 is at the index 1.
0, the shoe 16B located on the left side (the position indicated by the solid line in FIG. 1) communicates with the coin accumulating tube 24.

Further, when the cam follower 13 is in contact with the cam surface 12A of the cam 12, that is, when the scale 7 is in the indicated area of the index 10, it is on the right (the position indicated by the imaginary line in FIG. 1),
The chute 16A communicates with a fixed chute 26 that communicates with the coin bagging nozzle 25.

In the figure, 27 is a bag holding link fitted to the outer periphery of the cap 25, and 28 is an openable bottom plate that closes the lower end of the coin accumulating tube 24.

This device has the above-mentioned configuration, and when you want to count and bag coins, you operate the dial 5.
When the scale 7 for counting from 00 to 5000 is aligned with the index 10, the cam surface 12A of the cam 12 faces the cam follower 13, the chute 16 is switched, and the chute 16A
communicates with the fixed chute 26, allowing coins to flow into the coin bagging nozzle 25.

Also, when the scale 8 is aligned with the index, the cam surface 12B faces the cam follower 13, and the chute 16 is switched to the chute 16.
B communicates with the coin accumulating tube 24, and all coins from the coin passage 1 flow into the coin accumulating tube 24.

Therefore, in the device of this invention, when the dial is rotated for counting and the scale is aligned with the indicated area of the index,
Since the chute is automatically switched, there is no risk of erroneous operation, and the coin counting setting, packaging number setting state, and chute switching can be confirmed at the same time by the indicator and the scale of the dial.

In addition, since the chute is mechanically switched by rotating the dial, the structure is simple, and durability and operability can be improved.
