Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a coin counting and packaging machine that sorts, counts, and wraps coins.

"Conventional technology" Conventionally, as a coin counting and packaging machine, for example,
Like the device described in Publication No. 53-86289, the device performs a wrapping operation in which a certain number of sorted and counted coins are stacked and packaged in a bar shape, and a counting operation in which the sorted and counted coins are stored in a coin bag in pieces. There is something to do, and in order to perform both of these actions,
A mechanism is used to switch the destination of the sorted coins.

FIG. 1 shows an example of a conventional device in which the chute switching operation in the above device is performed by a motor, in which a predetermined coin 3 is pressed and slid on a sorting course 2 by a conveyor belt 1.
In the case of a wrapping operation, a packaging chute 4 is arranged at the exit of the sorting course 2, and the coins 3 are fed into a wrapping mechanism (not shown) through this packaging chute 4 and wrapped, and in the case of a counting operation, A counting chute 5 is arranged at the exit of the sorting course 2, and the coins 3 are stored in a coin bag 6 attached to the tip of the counting chute 5 in a loose state. and,
These packaging chute 4 and counting chute 5 are integrally formed and are reciprocated by rotating a motor 9 connected via cams 7A, 7B and a link 8, and are selected at the exit section of the sorting course 2. It has come to be centrally located.

``Problems to be solved by the invention'' However, the work of positioning the packaging chute 4 or the counting chute 5 at the exit of the sorting course 2 is carried out as appropriate at the operator's discretion. If the machine is accidentally started with the counting chute 5 located at the exit of the course 2 and the coin bag 6 not attached to the counting chute 5, coins may be scattered on the floor or the like.

Furthermore, in the coin dispensing machine shown in Utility Model Application Publication No. 55-19263, a technology is disclosed that determines whether or not a tray is placed at the discharge port for stored coins, and prohibits the discharge of coins if there is no tray. Although it has been done,
Even if the conditions for determining whether or not coins can be ejected in this device are directly applied to the coin sorting and packaging machine, the above problem cannot be solved. That is, due to the difference in the objects to which coins are fed (receptacle and coin bag), it has not been possible to apply the technology related to coin ejection machines to coin sorting and packaging machines.

This invention was proposed in consideration of the above-mentioned circumstances, and its purpose is to prevent accidents when the coin bag is forgotten to be attached when coins should be sent into the coin bag.

``Means for Solving the Problems'' In order to achieve the above object, the present invention provides a counting chute to which a coin bag is attached at the exit of a sorting course where coins are sorted and counted, or a coin wrapping mechanism. In a coin counting and packaging machine in which a guiding packaging chute is selectively arranged and the coins are fed into one of them, the chute is attached to an end of the counting chute and is formed of a conductive material such as metal. A coin bag placed over the chute cap is sandwiched between the chute cap and a ring made of a conductive material such as metal, and a signal for determining whether or not the chute cap and ring are electrically connected is provided. an interface circuit for outputting an output; a chute determination means for outputting a determination signal indicating whether or not the counting chute is disposed at an exit portion of a sorting course; and a control circuit that outputs a signal to instruct the coin counter to start operation on the condition that the chute discriminating means determines the presence of a counting chute at the exit portion of the sorting course, is formed into a cylindrical shape and divided into a plurality of parts electrically insulated from each other in the circumferential direction at the contact portion with the ring, and further supplies a detection signal to the interface circuit at the divided part of the chute cap. The lead wires for each are connected to each other.

"Function" Since the chute cap and the ring become non-conductive when a coin bag is attached, it is possible to determine whether or not the coin bag is attached by the interface circuit, and the discrimination signal of this interface circuit and the It becomes possible to regulate the start of the apparatus according to the input state of the discrimination signal of the shoot discrimination means.

Also, since the lead wires leading to the interface circuit are both connected to the chute cap,
When the ring is moved to attach the coin bag to the chute cap, the lead wire does not interfere with the movement of the ring.

"Example" Hereinafter, an example of this invention will be described based on the drawings. In the figure, parts common to those of the conventional example are given the same reference numerals to simplify the explanation.

2 to 4 show examples of this invention. First, in FIG. 2, what is indicated by the reference numeral 10 is a chute cap. This shoot cap 1
0 is formed of a conductive material such as metal at the tip of the counting chute 5 into a cylindrical shape with its opening facing downward and widening toward the opening. In addition, this chute cap 10 includes
Coin bag 1 made of insulating material such as cloth or vinyl
The coin bag 11 is further held between the chute cap 10 and a ring 12 fitted on the outside of the chute cap 10. This ring 12 is made of a conductive material such as metal.

FIG. 3 shows in detail the structure of the vicinity of the chute base 10 according to this invention, in which the chute base 10 is connected to at least one lead 12 by an insulator 14.
The contact portions are electrically insulated from each other and divided into two parts, terminals 15, 15 are formed on each part, and lead wires 13, 13 are connected to these terminals 15, 15, respectively. This terminal 1
5 and 15 are rings 12 directly attached to the chute cap 10.
When they are in contact, that is, when the coin bag 11 is not attached to the chute cap 10, conduction occurs, and when the coin bag 11 is attached to the chute cap 10, they are insulated and non-conductive. The presence or absence of the coin bag 11 is detected by this.

Further, the lead wires 13, 13 are both connected to the coin bag 1.
These lead wires 1 are connected to the chute base 10 side, which does not move when installing
Trouble such as disconnection of wires 3 and 13 does not occur.

Also, cams 7A, 7 connected to a motor 9 that reciprocates the packaging chute 4 and the counting chute 5.
Switches SW1 and SW2 are provided close to B, and these switches SW1 and SW2 are operated by cams 7A and 7B, respectively, and are used for sorting course 2.
If counting chute 5 is placed at the exit of SW
1 is "open", SW2 is "closed", and when the sorting chute 4 is placed at the exit of the sorting course 2,
They are connected so that SW1 is "closed" and SW2 is "open". And these switches SW1, SW
By opening and closing the chute 2, it is determined whether the packaging chute 4 or the counting chute 5 is disposed at the exit of the sorting course 2.

In this way, the presence or absence of the coin bag 11 is detected and it is determined which of the counting chute 5 and the packaging chute 4 is placed at the exit of the sorting course 2,
The control circuit shown in FIG. 4 is operated by the output signals from these, and the operation of the coin counter is enabled only under certain conditions.

This control circuit will be explained based on a specific example of its operation. In FIG. 4, A represents an inverter, A represents a NAND gate, and the suffix indicates its number.Furthermore, the suffix ``a'' or ``b'' represents the upper and lower input terminals of each NAND gate, respectively. Furthermore, the part surrounded by a broken line in the figure is an interface circuit INT that connects the detection device and the control circuit.

First, a description will be given of the case that occurs most frequently, that is, the case where the coin bag is removed after the counting operation and the wrapping operation is performed while the counting chute 5 is placed at the exit of the sorting course 2. At this time, it is assumed that SW1 is in the "open" state, SW2 is in the "closed" state, and the terminals 15, 15 are electrically connected through the ring 12.

When the operator closes the setting switch SW3 and selects the wrapping operation, a low signal (hereinafter referred to as L) is output from SW3, and an L signal is output from SW2, which is input to the inverters ₁ , ₂ , and _3, respectively. The output H of the interface circuit INT, which is generated when the outputs of these inverters ₁ , ₂ , and ₃ and the terminals 15, 15 are electrically connected, is the input terminal _A1a to _A3 of each NAND gate _A1 to _A3 . a and A ₁ b to _{A 3} b, each input signal is H for A ₁ a, H for A ₁ b, L for A ₂ a, H for A ₂ b, and L for A ₃ a. Due to the input of , L is output from A ₁ and input to A ₄ a, and H is output from A ₂ and A ₃ and input to A ₆ . Furthermore, one output L of A ₆ is input to A ₄ b, and the H output from A ₄ is input to I ₅
is inverted, and the set completion signal SER becomes L.
This SER indicates whether the counting chute 5 or the packaging chute 4 is in the correct position in response to the operation of the setting switch SW3.In this case, the counting chute 5 is in the sorting course with no coin bag 11 attached. Since it is located at the exit of No. 2, L indicating that the setting is not completed will be output.

On the other hand, the output L of A ₆ is inverted by I ₄ and H is input to A ₅ a, and when the H signal of the clear signal QCZ due to the operator's starting operation is input to A ₅ b, L is output from A ₅ . and further inverted at _I6 to output the shoot switching signal.
The WCE H signal is output.

That is, SER becomes L, indicating that the set is not completed, thereby disabling the starting operation of the machine, and at the same time, WCE becomes H, the motor 9 starts, and the packaging chute 4 starts the sorting course 2. It is disposed at the exit portion, and is accordingly operated by the cams 7A and 7B to close SW1 and open SW2. Then, L is output from SW1, H is output from SW2, and L is output from SW3 as before, and to each NAND gate, A ₁ a is H, A ₁ b is L,
A ₂ b is H, A ₂ b is H, A ₃ a is L, A ₃ b is L, A ₄ a is H, A ₆ a is L, A ₆ b is H, and A ₆ is input. Output H is input to _A4b and L is output from _A4 . Then, the output L of _A4 is inverted by _I5 , and the H output of SER indicates the completion of setting, and the output H of _A6 is inverted by _I4 and input as L to _A5a , so it is cleared. Regardless of the state of the signal QCZ, H is output from _A5 , and this signal is further inverted at _I6 , and the shoot switching signal WCE becomes L.
At this time, since WCE is L, the motor 9 stops with the packaging chute 4 placed at the exit of the sorting course 2, and SER becomes H, indicating that the setting is complete and the machine is ready to start. It's summery. When the machine is started in this state, the coins are sent to the lower packaging mechanism (not shown) through the packaging chute 4 and packaged, so that they are not scattered on the floor or the like. Furthermore, if the coin bag 11 is attached to the counting chute 5 in this state, L will be output from the interface circuit, but due to the characteristics of the NAND gate _A1 , even if the input of _A1a is L, it will not be H. too
As long as the input of A ₁ b is L, its output will be H and will not affect the control circuit.

Next, a case will be described in which a counting operation is to be performed without attaching the coin bag 11 to a machine that has been left with the packaging gate 4 positioned at the exit of the sorting course 2 after performing the wrapping operation. At this time, since the packaging gate 4 is located at the exit of the sorting course 2, SW1 is closed and SW2 is opened.
Coin bag 11 is a chute cap 10 with a counting chute 5
It is assumed that the terminals 15, 15 are in a conductive state because they are not attached to the terminals.

First, when the operator opens the setting switch SW3 and instructs the counting operation, H is output from SW3, L from SW1, and H from SW2, and I ₁ , I ₂ ,
I ₃ and these signals and terminal 1
The H signal of the interface circuit INT, which is generated when the gates 5 and 15 are made conductive, is input to the NAND gates _A1 to _A3 . At this time, A ₁ a is H,
A ₁ b is L, A ₂ a is H, A ₂ b is L, A ₃ a is L, A ₃ b is H, and A ₁ outputs H, A ₂ outputs H, and A ₃ outputs H. As a result, _A6 becomes L, and this L and the output H of _A1 make the output of _A4 H, and this output H is further inverted by _I5 , and the reset completion signal SER becomes H, indicating that the reset is not yet completed. This signals completion and disables the machine starting operation.

On the other hand, when the output L of A ₆ is inverted and H is input to A ₅ a, and the H of the clear signal QCZ is input to A ₅ b, L is output from A ₆ and inverted by I ₆ to switch the shoot. Signal WCE of H is output.

That is, SER goes low to indicate that the set is not completed, which disables starting the machine.
At the same time, the motor 9 is started by H of WCE, and the counting chute 5 is placed at the exit of the sorting course 2.
SW1 is opened and SW2 is closed. Then, H is output from SW1, L is output from SW2,
These are inverted by inverters ₁ , ₂ , _{and 3} ,
The interface circuit INT generated by connecting these outputs to terminals 15 and 15
The H signal is input to the NAND gates _A1 to _A3 .
At this time, A ₁ a is H, A ₁ b is H, A ₂ a is L, A ₂ b is L, A ₃ is H, A ₃ b is H, A ₁ to L, A ₂ to H, A ₃ L is output from each, and this causes A ₆ to become H, and by this H and L of A ₁ ,
H is continuously output from _A4 , and is further inverted at _I5 , so that the reset completion signal SER becomes L, indicating that the reset is not completed. Also, when the H of _A6 is inverted by _I4 and L is input to _A5a , H is output from _A5 , which is further inverted by _I6 , and the shoot switching signal WCE is output.
The L signal is output, and the motor 9 does not operate and the counter chute 5 remains set.

Therefore, in this state, the set completion signal
Since SER is L, the machine cannot be started, and for example, the machine is prevented from being started before the coin bag 11 is attached. and,
When the operator attaches the coin bag 11 to the chute cap 10, the ring 12 cannot directly contact the chute cap 10, so the terminals 15, 15 are not electrically connected, and the output of the interface circuit becomes L.
L is input to A ₁ a, and the output of A ₁ becomes H,
H is input to A ₄ a, H is input to A ₄ b, and the output of A ₄ becomes L. Furthermore, this L is inverted by I ₅ and becomes H, and the set completion signal SER becomes H, and the machine starts. It is possible to start.

Each operation described above will be summarized and explained. first,
If the counting chute 5 is located at the exit of the sorting course 2 and the coin bag 11 is not attached to the counting chute 5 and the wrapping operation is to be performed, the machine will first be unable to start; The motor 9 is then rotated to position the packaging chute 4 at the exit of the sorting track 2, after which the machine can be started. Also, packaging chute 4 is in sorting course 2.
If a counting operation is to be performed while the machine is placed at the exit of the sorting course 2, first the machine will not be able to start, then the motor 9 will rotate and the counting chute 5 will be placed at the exit of the sorting course 2. coin bag 1
1 is not attached to the chute cap 10, the machine can only be started after it is attached.

In addition, in Fig. 4, the ground connected to the power supply voltage +24V via a resistor and the chute cap 1
0 and the ground connected via the lead wire 13 are both frame grounds, and the other grounds are signal grounds, and both are in an insulated state.

Therefore, when the coin bag is not attached,
The potential of the input terminal BD of the interface circuit is supplied with +24V of the frame ground, and the output terminal of the interface circuit has a potential of +5V (H), which is approximately equal to the power supply voltage of the control circuit. When the coin bag is attached, the frame ground +24V is not supplied to the input terminal BD of the interface circuit, and the same potential as the signal ground, that is, OV.
(L).

Further, the setting completion signal SER may be used to operate the power source for starting the coin counting and packaging machine, thereby automatically starting operation of the machine after the setting is completed.

``Effects of the invention'' As is clear from the above explanation, this invention consists of a chute cap attached to the end of the counting chute and a ring that clamps the coin bag between the chute cap and the chute cap, which are made of a conductive material. The interface circuit determines whether or not these chute caps and rings are electrically connected, and the chute determining means determines whether or not the counting chute is disposed at the exit of the sorting course. The signal obtained from the circuit and the chute discriminating means restricts the start of operation of the coin counter, so that when the device is in the counting mode and the coin bag is not attached to the chute mouthpiece of the counting chute, This has the effect of preventing accidents caused by erroneous operation, such as ejecting coins from the counting chute and causing coins to be scattered on the floor or the like and lost.

Also, since the lead wires leading to the interface circuit are both connected to the chute base,
When the ring is moved to attach the coin bag to the chute cap, the lead wire does not obstruct the movement of the ring, thereby preventing breakage of the lead wire. You can get the effect that you can.
