Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing device for handling accumulated coins in a coin packaging machine.

In a coin wrapping machine, coins are continuously fed into a cartridge while being sorted and counted one by one, and when the number of coins reaches the packaging unit, the supply is temporarily stopped, and at the same time, the stacked coin collection is wrapped. The package is sent to a mechanical unit and automatically wrapped.

However, when the coins are stacked in the cartridge, several coins often become oblique or upright in the cartridge, resulting in so-called misalignment.
If such irregularities occur, the coins cannot be packaged. Therefore, in conventional devices, the unevenness is corrected by applying vibration to the cartridge for a predetermined period of time, and if the unevenness is not corrected even at a predetermined timing, the detection device detects the misalignment, and the signal indicates that the unevenness has already been detected. The camshaft that drives the packaging mechanism, which had started rotating, is switched to reverse operation, and the irregularity detection operation continues until the camshaft returns to its initial position (one rotation stop position) before the start of packaging operation. Once the misalignment is corrected, the camshaft is returned to normal rotation and the wrapping operation is continued.

Furthermore, if the misalignment is not corrected and the camshaft returns to the one rotation stop position, the entire machine is stopped and the misaligned coins are removed. However, depending on the degree of misalignment, even after returning to the one-rotation stop position, if the coins are not removed and vibrated by the vibration device for a while, the stacked state may be restored to normal.

In the case of conventional machines, even if the machine seems to recover normally, once it returns to the stop position for one rotation, it is immediately rejected as an irregular coin and the entire machine is stopped, so after stopping, the machine must be restarted manually. Moreover, the efficiency was poor. The present invention aims to eliminate the above-mentioned drawbacks,
If the misalignment is resolved during the reverse operation or within a certain period of time after returning to the one-rotation stop position before starting the wrapping operation, the wrapping operation will start again and counting and packaging will be completed without stopping the entire machine. It is an attempt to continue.

Therefore, only if the misalignment is not resolved even after a certain period of time has passed after returning to the stop position for one rotation, the entire machine is stopped.
This eliminates irregular coins. However, this ratio is relatively small, and a considerable improvement in efficiency can be expected compared to the conventional method. Embodiments of the present invention will be described below with reference to the accompanying drawings.

Referring now to FIGS. 1-6, a coin accumulation wrapping mechanism of a coin wrapping machine is illustrated.

FIG. 1 is a perspective view of the exploded parts arrangement of the coin wrapping machine, FIG. 2 is a top view of the coin counting section, FIG. 3 is a side view of the coin stacking section and the wrapping section, and FIG. FIG. 4 is a cross-sectional view of the accumulating cartridge showing the coin misalignment state, FIG. 5 is a top view of the coin wrapping section, and FIG. 6 is an enlarged view of the setting cam switch group. Coins sent through the sorting passage 12 by the transfer belt 10 are sent through the sorting passage 12.
The star gear 14a of the counter 14 placed on the side of the counter is rotated by a predetermined angle to advance the counter by one.

Thereafter, the coins fall into a cylindrical cartridge 16 placed below the end of the sorting channel 12. The cartridge 1
6 are formed with through holes 18 and 20 located in a straight line in the transverse direction, a light projector 22 is disposed in one of the through holes 18, and a light receiver 24 is disposed in the other through hole 20.

These light emitter 22 and light receiver 24 are connected to the cartridge 16.
It constitutes a photoelectric misalignment detection device that detects whether the coins are correctly aligned and stacked inside. That is, when a predetermined number of coins are accumulated in the cartridge 16, if there is an irregularity as shown in a and b in FIG. Obstruction,
As a result, the photoreceiver 24 generates an irregular signal. An electromagnetic shutter 26 having two double-opening plates is attached to the lower part of the cartridge 16.

A coin wrapping mechanism is arranged below the shutter 26. This coin wrapping mechanism has a coin receiver 28 located below the shutter 126, and the coin receiver 28 is moved up and down along a guide shaft 30 so as to move up and down while maintaining a coaxial relationship with the cartridge 16. It is designed to be able to move. Three wrapping rollers 32, 34, and 36 are arranged equiangularly around the coin receiver 28. The wrapping rollers are actuated toward and away from the axis of the cartridge 16 by a lower linkage and rotated by a gear set 38. When a predetermined number of coins are fed into the cartridge 16 and stacked without causing any misalignment, the shutter 26 opens and the coins 2 in FIG.
A stack of coins is dropped into the coin receiver 28 located at the position indicated by the dotted chain line.

The coin receiver 28 then descends along the guide shaft 30 to position the stacked coins between the three wrapping rollers. Then, the wrapping roller wraps the wrapping paper 40 around the stacked coins while rotating the coins, and the crimping claws 42 swage both ends of the wrapping paper to complete the wrapping. The above configuration and operation have already been described in Japanese Patent Application No. 52-96417 (Japanese Patent Application Laid-open No. 54-31
Since it is disclosed in detail in Japanese Patent Publication No. 382), further detailed explanation will be omitted here.

The series of operations described above are controlled by the one-rotation camshaft 46.

This camshaft 46 is driven by a motor 50 (FIG. 6) via an electromagnetic latch 48 (FIG. 6). Detection of misalignment, opening of the shutter 26, etc. are performed by a micro switch group 5 operated by a cam group 52 attached to the cam shaft 46.
4. Fig. 6 shows a part of it. The cam 56 is a cam that stops one rotation, the cam 58 is a cam that normally opens the shutter 26, and the cam 60 is a timing cam for detecting misalignment, and each has recesses 56a, 58a, and 60a. Micro switches MSl, MS2, and MS3 are attached to these cams 56, 58, and 60 so as to be operated by the protrusions of the cams. The microswitches MS1 and MS2 are connected to the control circuit 62, and the microswitch MS3 is connected to the control circuit 62 via the misalignment detection circuit 64. Control circuit 62 then controls clutch 48 and motor 50. The conventional control circuit 62 performs control as follows.

That is, when the counting end signal is generated in the counting section, the electromagnetic clutch 48 is excited by the control circuit, the rotation of the motor 50 is transmitted to the camshaft 46, and the cam group 56, 58 fixed to the camshaft 46 is activated. and 60 rotate counterclockwise in the drawing. If the stack of coins is detected as normal during the irregularity detection period defined by the cam 60, the shutter 26 is opened by the cam 58, the stacked coins are transferred to the coin receiver 28, and wrapped by the wrapping roller. , cam 56
As a result, the electromagnetic clutch 48 is deenergized and the camshaft 46 is stopped at the one rotation stop position. If misalignment is detected at the time of misalignment detection, the control circuit reverses the motor 50 and rotates the camshaft 46 clockwise.

Then, the camshaft is thinned out until it returns to its initial position, that is, the one-rotation stop position, and then a misalignment detection operation is performed. If the misalignment is corrected during that time, the control circuit corrects the motor and reverses the camshaft, correcting the camshaft. Then, the wrapping operation described above is carried out.
If the camshaft returns to the one rotation stop position without correcting the misalignment, the entire packaging machine is stopped and the misaligned coins are removed. In contrast to the conventional control circuit as described above, the present invention achieves the object of the present invention by using a control circuit as shown in FIG.

In FIG. 7, the start button signal and stop button signal are signals from the start button and stop button for starting and stopping the counting and packaging operation.

When the start button is pressed, a high level start button signal is supplied to the set input S of the flip-flop FFl, and when the stop button is pressed, a high level stop button signal is supplied to the set input R through the 0R gate 0R1. . Assuming that the camshaft 46 is at the one-rotation stop position, both the NC contact (normally closed contact) of MS3 and the NO contact (normally open contact) of MS1 are open. FFl by start button signal
The Q output of becomes high level, which is a start signal and is output to a counter or the like. The next counting signal is a signal such as paper cut detection when normal accumulated coins are sent to the wrapping section and wrapped, and is a signal to start the next counting by confirming the start of wrapping. The shutter open signal is a signal that detects that the shutters are opened, regardless of whether the shutters are not aligned properly or not. The photo jam signal is a signal when an irregularity is occurring, and in this embodiment, it is a signal from the light receiver 24 of the photoelectric detection device, and is a signal that becomes high level when an irregularity occurs. Note that any misalignment detection device can be used in the present invention as long as it is capable of constantly detecting misalignment. M.S.
3, one end is grounded, and the other end is connected to the voltage signal generation circuit 72.
is connected to the inverter NVl via the inverter NVl.

Therefore, when MS3 is closed, the output of INV1 is high level, and when MS3 is open, the output of NV1 is low level. The output of INVl is sent to one input of the AND gate ANDl via the inverter INV2, and the output of ANDl
The other power of is connected to the Q output of FFl. The output of ANDl is the pipe rotation motor 1 drive signal. This pipe rotation motor 1 drive signal is a drive signal for a conventionally known vibration generator that vibrates the cartridge in order to reduce the occurrence of misalignment of accumulated coins. Further, when the misalignment defined by the cam 60 is detected, the pipe alignment is stopped. N.V.
The output of l is further passed through a CR circuit 74 to an AND gate A.
Connected to one side of ND2.

A photo jam signal is applied to the other input of this AND2. The output of AND2 is sent to the flip-flop FF via the inverter NV3 and the noise removal filter circuit 76.
It is connected to the set input S of 3. The Q output of this FF3 is an irregularity signal, and this irregularity signal indicates that the FF3 is irregular when the NC contact of MS3 is closed by the cam 60.
3, the misalignment is eliminated, and F
The photo jam signal, which is also sent to the reset input R of the F3, becomes low level and is held until the FF3 is reset. The counter 14, which starts counting coins upon receiving the start signal or the next counting signal, outputs a counting end signal to the set input of the flip-flop FF2 to set the flip-flop FF2 when a predetermined count is reached.

A shutter open signal is sent to the FF2 set input. The Q output of FF2 is connected to one input of an AND gate AND3, and the other input of AND3 is connected to the
Connected to the Q output of F3. The output of AND3 is 0
It is connected to one input of an AND gate AND4 via an R gate 0R2. The other input of AND4 is
AND4 outputs an electromagnetic clutch signal that energizes electromagnetic clutch 48.
One end of the one-rotation stop microswitch MSl is grounded, and the other end is connected to the inverter INV4 via the voltage signal generation circuit 78.

Therefore, when MSl is closed, the output of NV4 is high level, and when MSl is open, the output of INV4 is low level. The output of INV4 is connected to the input of 0R2 and to one input of an AND gate AND5. The other input of this AND5 is FF
The output is directly connected to one input of each of a NOR gate NORl and an AND gate AND7, and is connected to the other input via a delay circuit D1. The output of NOR1 is a packaging motor forward rotation signal, and the output of AND7 is a packaging motor reverse rotation signal when the items are not aligned. The output of INV4 is further connected to the inverter INV
5 to A to one of the D gates AND8.

The other input of AND8 is connected to the Q output of FF3. The output of AND8 is connected to monostable multivibrator MM via delay circuit D2 and inverter INV6.
The output of MMl is connected to the inverter INV7. The output of this INV7 is
This is a shutter signal that opens the shutter 26 for a certain period of time when the shutters are not aligned, and is an FF that holds the start signal.
This signal is sent to the glue set input R via 0R1 to stop the entire packaging machine. Next, the operation of the control circuit according to the present invention shown in FIG. 7 will be explained. When the boot button is pressed, the start button signal is input to the S input of FFl, the Q output of FFl becomes high level, and the high level start signal is output to the counter 14 to start counting.

At this time, the NC contact of MS3 is open, so INVl,
A high level signal, that is, an H signal, is applied to the other input of A-NDl via NV2, and the ANDl output becomes an H signal, the pipe ration device is activated, and the cartridge 4 begins to vibrate. Further, the start signal opens the gate of AND4. At this time, the NO contact of MSl is open, the INV4 output is a low level signal, that is, an L signal, and the counting end signal α from the counter has not yet been output, and FF2 is in the resetting state, so AND3 The output of 0R2 becomes an L signal, so the output of 0R2 also becomes an L signal, and the electromagnetic clutch 48 is not operating. Also. [Due to the L signal output of NV4, the AND5 output becomes an L signal, and therefore NO
The Rl output becomes an H signal, the AND7 output becomes an L signal, and the packaging motor 50 is in a normal rotation state. Furthermore, since the misalignment signal is an L signal, the misalignment shutter signal remains an L signal. When counting is completed, the counter outputs a counting end signal α,
Set FF2.

Regardless of whether it is misaligned or not, at this moment, the NC of MS3 is still open, so the Q output of FF3 is an H signal, and the A
The ND3 output becomes an H signal, and the AND4 outputs an H signal via 0R2, energizing the electromagnetic clutch 48 and rotating the camshaft 46. Then, the NO contact of MSl is grounded, the NV4 output becomes an H signal, and the AND4 output becomes an H signal until it returns to the one rotation stop position (the NO contact of MSl is in an open state) regardless of the AND3 output. When the camshaft 46 rotates and the mital switch MS3 of the timing cam 60 engages with its recess to ground the NC contact of MS3, the output of NVl becomes an H signal, and the H signal turns INV2. At the same time, the CR circuit 74 is manually operated to open the gate of AND2 for a certain period of time, and the photo jam signal is output to N.
It passes through to V3 to detect irregularities.

At this time, if it has already been accumulated normally, the photo jam signal is an L signal, so FF3 will not be set, and therefore, an uneven signal will not be output, and a normal rotation signal will continue to be output to the packaging motor. . Thus, the camshaft rotates further,
The shutter 26 is opened by the signal from the micro switch MS2 of the normally open cam 58, and the accumulated coins are moved to the coin receptacle 28, which has been waiting just below the shutter 1, by that time.
It then descends to the packaging mechanism and is wrapped. In response to the shutter open signal, FF2 is reset, and a next count signal is issued during packaging, and the counter restarts counting. When the camshaft further rotates once, the NO contact of MSl is opened, the NV4 output becomes an L signal, and the FF2
Since the Q output of is an L signal, the 0R2 output (is an L signal).
A signal is generated, and the transmission of driving force to the camshaft 46 by the electromagnetic clutch 48 is interrupted, and the rotation of the camshaft 46 is stopped at the one-rotation stop position. Now, due to the counting end signal α, the camshaft 46
rotates, the NC contact of MS3 is grounded, and it remains 0 for a certain period of time.
If the misalignment has not been resolved when the gate of D2 is opened, AND2, INV3, and the noise removal filter circuit 7
FF3 is set via 6 and outputs a high level mismatch signal.

Due to this high level uneven signal, the AND5 output becomes an H signal, NORl becomes an L signal, and the AND7 output becomes an H signal with a slight delay due to the delay circuit D1.
Reverse the packaging motor. This delay circuit D1 is provided for driving design conditions that take into consideration packaging motor inertia and the like. Also, although it is input to the irregular signal AND8,
Since it is not at the one-rotation stop position, the AN])8 output is in the L signal state. When the misalignment is resolved in the reverse process, the photo jam signal becomes an L signal, FF3 is immediately reset, the AND5 output becomes an L signal, and after first making the AND7 output an L signal, the capacitor of the delay circuit D1 is After discharging, an H signal (normal rotation signal ●) is output by AND6, and the wrapping operation changes.

When the misalignment is not resolved even during the reverse rotation and the rotation returns to the stop position, the packaging motor is switched to a normal rotation signal by opening the NO contact of MSl, and the inputs of AND8 both become H signals.

Furthermore, during the reverse rotation, the NC contact of MS3 is opened, and a pipe rotation and drive signal is output, causing the cartridge 16 to vibrate again. Also, the 1NV4 output is an L signal, and due to the misalignment, the Q output of FF3 is an L signal, so the electromagnetic clutch is de-energized and stops at the one-rotation stop position. AND
The output of 8 is input to the delay circuit D2, and the delay time is set to 1, for example.
If it is set to ~1.5 seconds, and the misalignment is not resolved even after the set time, the L signal is output from INV6, and the monostable multipipe radar MMl outputs a pulse from a certain period of time (arbitrary). The output pulse opens the shutter 26 to remove the uneven coins and resets FF2.Furthermore, the uneven coin shutter signal is sent to the R of FFl via 0R1.
input, resets the start hold signal, and resets the packaging machine. However, if the misalignment is resolved by pipe placement within 1 to 1.5 seconds after returning to the stop position for one rotation, FF3 is reset and the AND8 output is set to L.
The signal is switched to disable the monostable multivibrator MMl, and since the Q output of FF2 is the H signal, the electromagnetic clutch is re-energized and the wrapping operation is started. Switch to . According to the present invention, as described above, when the occurrence of misalignment is detected, the operation switches to reverse rotation, but since the misalignment continues to be detected, the misalignment occurs not only during the reverse operation but also within a certain period of time after returning to the one-rotation stop position. Once the alignment is resolved, the process shifts to the wrapping operation again, so
The rate of coin rejection and machine stoppage due to misalignment is drastically reduced, and overall efficiency can be improved.
