Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention involves feeding counted coins one by one into a stacking space between packaging rollers, stacking the coins one by one, and placing the stacked coins in the stacking space. The present invention relates to a control device used in a coin packaging machine.

[Technical background of the invention and its problems]

Conventional coin packaging machines, especially coin packaging machines that sequentially feed counted coins one by one into a space between wrapping rollers and stack them, and then wrap the stacked coins in the space. While stacking a number of coins, the stopped camshaft rotates once, and the time of one rotation changes the time for one cycle of wrapping a predetermined number of stacked coins and the operation timing of the wrapping roller, winding needle, etc. determined.

In the case of this type of packaging machine, at least the bottom of the space is closed during the period from coin stacking to the middle of folding the end face of the wrapping paper wound around the stacked hardened peripheral surface, and this support member is closed. The timing of movement from the position to the open position and the timing of movement to the closed position are also determined by the camshaft. Therefore, with this type of packaging machine, coin counting and stacking operations cannot be performed during one packaging cycle, and the unit time required for forming wrapped coins from the start of coin stacking to the completion of coin packaging. Since this takes a long time, there is a tendency to increase the rotational speed of the camshaft in order to shorten the required unit time. By the way, the weight of the wrapped coins that are sent out and dropped after the wrapping roller is released has a different weight depending on the packaging denomination or the number of stacked coins, and lightweight wrapped coins, poorly wrapped coins, etc. will fall in an unstable position. It is sent out while contacting the packaging roller,
It gets stuck between the packaging rollers and the falling time is irregular. Under such circumstances, if the camshaft rotates until the end of one rotation and the supporting member closes the bottom of the space at a certain time near the end of one packaging cycle, the product will not be delivered from the space between the packaging rollers. The wrapped coin ends up being caught between the wrapping roller and the supporting member. The support member also cannot completely close the bottom of the space, and one packaging cycle ends in this state, and the next predetermined number of coins are fed one by one into this space, and the wrapped coins and The next coin to be wrapped gets stuck between the wrapping rollers, the wrapping needle,
This will damage and deform the supporting member and the coin. [
Purpose of the Invention The present invention has been made in view of the above-mentioned drawbacks, and provides a coin wrapping machine that can reliably stack, wrap, and deliver coins, and that can contribute to speeding up the unit time required for forming wrapped coins. The purpose is to provide a control device.

[Summary of the invention]

The control device for a coin packaging machine according to the present invention is provided with a wrapped coin delivery detection unit on the packaged coin delivery passage for detecting delivery of the packaged coins from the space, and detects stacked coins based on a detection signal from the detection unit. The bottom support member for opening and closing the bottom of the space is returned from the open position to the closed position, and a blockage detection unit is provided to detect blockage of the bottom support member, and based on the blockage detection, the coin transfer unit and the coin counting unit detect coins. The transfer counting operation is restarted, and the transfer, counting, and stacking operations of the next coin are restarted on the condition that the coins are reliably stacked, wrapped, and sent out. .

, is movable from a closed position where the lower end of the space 22 formed by the packaging rollers 26, 26, 26 is closed to an open position where the lower end of the space is opened by swinging in a horizontal plane; When it is, the stacked coin 2
It has a lower support plate 27 as a lower support member that temporarily supports 3 and is swung by a swinging member (not shown). This rocking of the lower support plate 27 is caused by the lower support plate cam 29 attached to the camshaft 28 being caused by the cam follower 3 of the lower support plate 27.
0, centering around the axis 31.

This cam shaft 28 is attached to the machine frame of the packaging machine H and rotates, and in addition to the supporting plate cam 29, it also controls the amount of swing of the packaging roller to contact the stacked coins. A cam that controls the feeding amount of the wrapping paper, a cam that controls the folding needle that folds the end face of the wrapping paper, etc. (all not shown) are fixedly attached.

Further, a fixed position cam 32 that keeps the camshaft at a fixed position is provided at the top of the camshaft 28Q. is starting to stop.

This rotation of the camshaft 28 is performed using the motor M2 as a driving source.

That is, the gear 36 fixed to the rotating shaft 35 of the motor M2
The rotation of the drive shaft 38 is transmitted to the drive shaft 38 via the gear 37, and the rotation of the drive shaft 38 is transmitted to the clutch plate 39, and then to the pulley 40 loosely fitted to the drive shaft 38, and the rotation of the drive shaft 38 is transmitted to the pulley 40 loosely fitted to the drive shaft 38.
and a pulley 42. On the other hand, this drive shaft 38 has the packaging rollers 26, 26, 26
A pulley 43 for rotating is attached, and this pulley 43 is always rotating. Therefore, in the clutch plate 39, when the solenoid SDl is deenergized, the operating rod 43a moves around the fulcrum 44, the clutch is engaged, and the pulley 40 is rotated. Avoid details. Further, the lower region of the coin packaging mechanism C includes an opening/closing mechanism E for the lower support plate 27 that opens the packaged coin delivery passage 45 and a packaged coin delivery detection section D.

First, as shown in FIGS. 1 and 2, this opening/closing mechanism E has an arm 47 that is fixed to the lower end of the shaft 31 to which a support plate 27 is attached and is biased clockwise by a spring 46. , a roller 48 attached to the tip of this arm 47 is biased counterclockwise by a spring 49.
It is always in contact with the shaped stopper 50. This stopper 5
0 is rotatably attached to a shaft 51, and its bent portion 52
The lower support plate 27 is attached to the packaging rollers 26, 26, 26.
A notch 53 is formed to maintain the open position, which is evacuated from the closed position where the lower end of the space 22 is closed. Further, a roller 55 is attached to the tip of the bent short piece 54 of the stopper 50, and one end of a connecting piece 57 extending from the solenoid SD2 is connected to the back side of the long piece 56.

On the other hand, an operating lever 60 having a long arm 58 and a short arm 59 extending in a bifurcated manner is rotatably attached to a shaft 61 on the stopper 50, and the tip of the long arm 58 is connected to a roller 47 attached to an arm 47. , the long arm 58 and the short arm 59
A roller 55 attached to the short piece 54 of the stopper 50 is located in the branching gap between the two ends.

The packaged coin delivery detection unit D includes an inclined plate 62 facing the coin delivery passage 45, as shown in FIG. A switch MSW 4 is tiltably supported by a piece 63 and has an operating piece 64 abutting the inclined plate 62 on the support piece 63.

Therefore, the switch MSW4 is operated by the packaged coin 23 itself that has fallen down the delivery passageway 45, and the detection section D detects the delivery of the packaged coin from the space 22.

Next, the operation of this embodiment will be explained.

First, when wrapping coins, the support plate 27 is positioned below the wrapping rollers 26, 26, 26, so that coins can be stacked in the cylindrical space 22 between the rollers.

That is, the actuating lever 60 of the opening/closing mechanism E is operated to disengage the notch 53 of the stopper 50 and the roller 48, and position the support plate 27 around the shaft 31 in the lower area of the cylindrical space 22 of the packaging roller 26. let

Due to this closing operation of the lower support plate 27, the lower support plate detection switch MSW3 becomes 3-1 connected.

(See Figure 4) Next, after inserting coins into hopper 1, press mode selection switch S to select between wrapping mode and counting mode.
Insert Wl into the packaging mode side w.

In conjunction with this, the switches 65 and 66 are also set to the packaging mode side w. In this case, if the camshaft 28 is in the normal position, the switch MSW2 for the camshaft normal position is connected to 1-2, so if you press the start button SW2 in this state, the switch MSWl of the stop plate 13 will be connected to 12. , motors M1 and M2 start rotating.

As the motor M1 rotates, the coins pass through the coin transfer section A and the coin counting section B, pass through the guide path 21, and are stacked on the support plate 27.

However, when the counting unit B counts a predetermined number of coins,
A cam (not shown) on the camshaft 28, which operates synchronously with this, connects the stop plate 13 through a link (not shown).
is fitted into the hole 11 of the holed gear 12, and the supply of coins c is stopped.

Due to this operation of the stop plate 13, the switch MSW1 is connected to the power switch D, and the counting motor M1 is stopped.

However, this 1-3 connection of the switch MSWl deenergizes the solenoid SDl for the clutch, so that the actuating rod 43a of the clutch is lowered and the clutch plate 39 and the pulley 40 are brought into engagement.

Therefore, the pulley 40 is rotated by the drive shaft 38, and the camshaft 28 is rotated once from its fixed position through the belt 41 and the pulley 42, and the various cams on this shaft perform the wrapping operation. It is done.

One rotation of this camshaft 28 corresponds to one packaging cycle. When packaging is completed in the middle of one packaging cycle, the lower support plate 27 is released from the cylindrical space 22 by the cam 29 of the camshaft 28.

In other words, this lower support plate detection switch MSW3 is 2-C.
It becomes a connection. Due to the relief of the support plate 27, the wrapped coins 23 fall through the delivery passage 45.

Due to this fall, the packaged coin detection switch MSW4 becomes 1-3 connection at H time, the lower support plate solenoid SD2 is energized, the stop plate 50 is released, and the lower support plate 27 is not obstructed by this stop plate 50. In other words, the roller 48 can operate without coming into contact with the stop plate 50. The lower support plate 27 is returned to the closed position of the cylindrical space 22 by the elastic force of the spring 46, and the lower support plate switch MSW3 serving as a blockage detection section is connected in 3-1.

On the other hand, just before this wrapping operation is completed, that is, just before the camshaft 28 makes one revolution, the stop plate 13 locks the gear with a hole 12 by a link (not shown) connected to the cam of the camshaft 28. solve.

Due to this release, the stop plate detection switch MSWl becomes 1.
-2 connections.

When the camshaft 28 completes one regular rotation in this state, the camshaft fixed position switch MSW2, which had been switched to 1-3 contacts while the camshaft 28 was rotating, becomes connected to 12, and the solenoid SDl is energized. The engagement between the clutch plate 39 and the pulley 40 is released, the camshaft 28 is stopped at the regular position, and one packaging cycle is completed.

At the same time, the counting motor M1 is started again, and the same coin transfer, counting, and piling operations as described above are started. By the way, the above-mentioned one wrapping cycle is an example in which the wrapped coin detection switch MSW4 is operated with a wrapped coin. However, the timing at which the wrapped coin detection switch MSW4 is activated with a wrapped coin varies depending on the wrapped coin denomination, the number of wrapped coins, and the falling posture of each wrapped coin. Switch MSW4 may also be operated. In this case, the stop plate detection switch MSWl is connected to the monopole D, and the camshaft fixed position switch M
When SW2 is in the 1-2 connection state, the wrapped coin detection switch MSW4 is activated by a falling wrapped coin and temporarily becomes connected to 1Hα, and the lower support plate solenoid SD2 is energized to move the lower support plate 27 to the closed position. Then, the switch MSW3 for the support plate becomes 13 connected and the counting motor M
1 starts again.

However, if the coin does not fall (for example, the cylindrical space 22
(If a coin jams in the bottom support plate 27, the bottom support plate 27 malfunctions, etc.) The switch MSW4 continues the 1-2 connection, and the bottom support plate solenoid SD2 is not energized. Therefore, the lower support plate 27 once released cannot close the cylindrical space 22.

In other words, the support plate 27 does not exist in the normal position when packaging is performed. Therefore, the lower support plate detection switch MSW3 is connected to the 2nd (self) connection, so the motor M1 does not rotate and the coins are not fed into the wrapping mechanism C.

In addition, when counting coins, press the mode changeover switch SW.
Insert l into C side.

By turning on this switch SWl, switch 6 of synchronous operation
5 and 66 also fall on the C side.

Therefore, the packaging motor M2 does not rotate, and only the counting motor M1 can rotate. That is, first, the operator swings the operating lever 60 clockwise to release the lower support plate 2.
7 in the open position and press the start switch SW2 in this state, the stop plate 13 releases the locking of the holed gear 12 by the operating rod 18 of this switch, and the stop plate detection switch MSWl is set to 1? Use D connection.

On the other hand, if the camshaft 28 is also in the normal position, the camshaft fixed position switch MSW2 is in the 1H2 connection.

Furthermore, the lower support plate detection switch MSW3 has a 2→D connection because the lower support plate 27 is missing.

In this way, a drive circuit for the counting motor M1 is formed, and the motor M1 rotates.

The rotation of the motor M1 rotates the rotary disk 4 and the belt 6, and the coins c rotate the star wheel 7, and the counter 8 counts the number of coins.

This counted coin is on taxiway 21. The coins are stored in the coin storage body 67 through the cylindrical space 22. As described above, according to the present invention, a packaged coin delivery detection section is provided on the packaged coin delivery path for detecting delivery of the packaged coin from the space between the packaging rollers, and based on the detection signal of this detection section, the packaged coin delivery detection section is provided on the packaged coin delivery path. The lower support member for opening and closing the lower surface is returned from the open position to the closed position, and furthermore, a blockage detection section is provided to detect blockage of the lower support member, and the coin transfer counting operation is restarted based on the blockage detection. Therefore, coins can be stacked, wrapped, and sent out reliably, and the unit time required for forming wrapped coins can be speeded up.
