Abstract

PURPOSE:To improve the work efficiency at the time of delivering coins by constituting the title device so that when accumulated coins on a shelf part reach the number of piece to be packed, the shelf part concerned is allowed to descend at a high speed, and when this shelf part reaches a decelerating position, it is allowed to descend at a low speed, and also, when the shelf part reaches a fixed position, it is stopped. CONSTITUTION:When coins in an accumulating part reach the number of piece to be packed, an accelerating signal (i) is outputted to an accumulating motor 14 from an acceleration/ deceleration time pulse output part 26, and the accumulating motor 14 is driven at high speed. When a decelerating position detecting sensor 17 is turned on, a decelerating signal (m) is outputted to the accumulating motor 14 from the acceleration/deceleration time pulse output part 26, and the accumulating motor 14 is driven to be decelerated. Also, whether a fixed position signal (k) for showing a fact that a fixed position detecting sensor 18 is turned on is outputted to the acceleration/deceleration time pulse output part 26 or not is decided, and in the case of YES, the output of the decelerating signal (m) outputted to the accumulating motor 14 from the acceleration/deceleration time pulse output part 26 is stopped, and the accumulating motor 14 is stopped. In such a way, the accumulating workability of coins can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a coin stacking device that can transfer stacked coins from a stacking section to a packaging mechanism in a short time.

"Prior Art" Conventionally, as a coin stacking device for arranging coins in a stacked state, for example, the one shown in Japanese Patent Application Laid-Open No. 62-208329 or the one shown in Japanese Patent Application Laid-Open No. 58-171318 is known. ing.

This type of coin stacking device lowers a pair of shelves, which are spaced apart from each other according to the size of the coin diameter, intermittently while maintaining the same height. Yes, the coins are stacked one by one on the upper part of the stacking part, and further, when the number of coins reaching the number of wrapped coins is stacked on the shelf part, the supply of coins to the shelf part is stopped, Moreover, by continuously lowering the accumulated coins on the shelf part by a certain distance, the accumulated coins on the shelf part are delivered to the shutter located below.

The coins delivered onto the shutter fall when the shutter is opened, and are delivered to a support member that has been waiting to rise beforehand, and after this, the support member descends. This allows it to be guided into the wrapping mechanism below.

``Problems to be Solved by the Invention'' By the way, in the above-mentioned coin stacking device, a series of operations such as raising, waiting, and lowering the supporting member are performed by a cam mechanism. There is a certain limit to the waiting time of the supporting member, so it is necessary to shorten as much as possible the time from when coin accumulation is completed until the coins are delivered to the shutter below.

However, depending on the number of packaging sheets, which is the number of sheets accumulated,
A lot of time is required for the delivery.

That is, in the above-mentioned coin stacking device, the coins are stacked on the shelf part with the top end of the stacked coins aligned with the top end of the stacking part where the coins are stacked, and further,
When this stacking operation is completed (in other words, the number of coins has reached the packaging number), the shelf is lowered continuously and the stacked coins are transferred from the stacking position to the shutter. The smaller the number of coins accumulated, the longer the distance from the coin accumulation position to the delivery of the coins to the shutter.
Therefore, a lot of time is required for the delivery.

For example, it is better to collect 40 coins such as the American 25 cent coin, or 20 coins called a half-lap, than the usual 50 coins for Japanese intermittent loans. , a long transfer distance and time required for transferring the coins from the accumulation position to the shutter are required.

In order to deal with this problem, control is provided in which the accumulating motor (as shown) that lowers the shelf is driven at high speed, and the accumulating motor is abruptly stopped when the coins are delivered to the shutter. It is good to do this, but on the other hand,
If such an integrated motor is driven at high speed and stopped suddenly, the integrated motor will lose synchronization and the shelf will pass the normal position where it should stop. When attempting to accumulate coins on the shelf, it is necessary to vertically align the shelf again, resulting in poor work efficiency.

This invention was made in view of the above circumstances, and
The purpose of the present invention is to provide a method and mechanism for driving an accumulating motor in a coin accumulating device, which can transfer coins from a coin accumulating position to a shutter at high speed without causing the accumulating motor to step out, and improve work efficiency during coin transfer. shall be.

"Means for Solving the Problem" In order to achieve the above object, in the first invention, a pair of shelves whose mutual interval is set to the size of the coin diameter are intermittently placed at the same height. While lowering the coins, the coins are stacked one by one on the shelf, and when the number of coins that have reached the number of wrapped coins is stacked on the shelf, the coins are placed on the shelf. A method for driving an accumulating motor in a coin accumulating device in which the supply of coins is stopped and the shelf is continuously lowered to transfer the coins on the shelf onto a shutter located below, A first method for detecting that the number of coins accumulated on the shelf reaches the number of coins to be wrapped.
a second step of lowering the shelf on which the number of accumulated coins in the package is placed; and a second step of lowering the shelf on which the number of accumulated coins is placed, and that the shelf descending at high speed reaches a deceleration position near the upper part of the shutter. a third step of detecting, a fourth step of lowering the shelf that has reached the deceleration position at a low speed, and a step of lowering the shelf at a low speed,
A fifth step of detecting that the accumulated coins have reached a fixed position where they can be placed on the shutter and stopping the descent of the shelf that has reached the fixed position drives the accumulating motor in the coin accumulating device. I have to.

In the second invention, there is provided a number comparison unit for detecting that the number of coins accumulated on the shelf has reached a packaging number, and a rotating body that is provided in conjunction with the lowering of the shelf and has one detection point. ,
a deceleration position detection sensor that detects a detection point on the rotating body and detects that the shelf has reached a deceleration position near the upper side of the shutter; a fixed position detection sensor for detecting that the accumulated coins have reached a fixed position where they can be placed on the shutter; and a fixed position detection sensor for driving the accumulating motor at high speed according to the detection by the number comparison section; In response, the accumulating motor that was being driven at high speed is switched to low-speed driving, and further, in response to the detection by the fixed position detection sensor, the accumulating motor that was being driven at low speed is stopped. A driving mechanism for the integrated motor is configured.

According to the third aspect of the present invention, the number comparing unit detects that the number of coins accumulated on the shelf has reached the packaging number, and the number comparing unit is provided so as to be interlocked with the lowering of the shelf. A rotating body having two detection points, and detecting the first detection point to detect that the shelf has reached a deceleration position near the shutter, and detecting the second detection point. A detection sensor detects that the accumulated coins on the shelf have reached a fixed position where they can be placed on the shutter, and a accumulating motor is driven at high speed in accordance with the detection by the number comparison section. In response to the detection of the first detection point, the integrated motor that was being driven at high speed is switched to low speed drive, and further,
A driving mechanism for the accumulating motor in the coin accumulating device is constituted by a control device that stops driving the accumulating motor that has been driven at a low speed in response to the detection of the second detection point by the detection sensor.

"Function" According to the first invention, when the number of coins accumulated on the shelf reaches the number of wrapped coins, the shelf is lowered at high speed, and then, when the shelf reaches the deceleration position I, the shelf is lowered at high speed. Since the shelf is lowered at a low speed and the shelf is stopped from descending when it reaches a fixed position, the stacking motor is prevented from stepping out and the number of packaging sheets is lowered. This prevents the accumulated coins accumulated numerically from passing over a fixed position where they can be placed on the shutter.

According to the second and third inventions, the rotating body that operates in conjunction with the lowering of the shelf and the detection point of this rotating body are detected to indicate that the shelf has reached a deceleration position or has reached a home position. Detection sensors such as a deceleration position detection sensor and a fixed position detection sensor are provided to indicate that the deceleration position has been reached, and the integrated motor is accelerated or decelerated in accordance with the output of the detection sensor, so that the integrated motor may similarly step out. This prevents the accumulated coins accumulated to the number of wrapped coins from passing past the fixed position where they can all be placed on the shutter.

“Example” A first example of the coin accumulating device according to the present invention is shown in FIGS. 1 to 5.
This will be explained with reference to the figure (corresponding to MJ requirements 1 and 2).

First, the schematic structure of the coin stacking device will be explained with reference to FIGS. 1 to 3. What is indicated by the symbol l in these figures is a coin passage through which coins supplied from a rotating disk (when shown) are sent out one by one along the surface direction of the disk.

The coin passage 1 is composed of a slide plate IA on which coins slide, and a conveyor belt IB provided above and close to the slide plate IA. By sandwiching the coins between the slide plate IA and driving the conveyor belt IB, the coins are transferred to the stacking section between the stacking drums 2, 2 (described later) and the vertically provided coin guides 3, 3. 4 then 1
It is possible to send one sheet at a time.

Further, the front position of the coin passage 1 is provided so that the coins sent by the coin passage 1 are prevented from going straight and jumping out to the outside, and the upper ends of the accumulated coins accumulated in the accumulation part 4 are placed in the accumulation part 4. A regulating plate 5 is provided in the middle of the coin passage 1 to detect and count coins sent through the coin passage l. A counting sensor 6 (described later) and a stopper (as shown) that interrupts the feeding of coins to the stacking section 4 based on the counting result of the counting sensor 6 are provided.

The stacking drums 2, 2 forming the stacking section 4 are moved intermittently in synchronization with the coin feeding cycle and in mutually opposite directions (arrow entry direction, arrow entry direction, Around these stacking drums 2, 2, there are spiral shelf portions 7, 7 which are opposite to each other and have the same phase. each formed.

These shelf sections 7 receive the coins sent through the coin passage 1 from below, and stack the coins in the llJ# state while contacting the coin guides 3 located on the front and rear sides. The support positions 7A and 7A of the stacked coins are set at the same height when the top end of the stacked coins is aligned with the top end of the stacking section 4 (according to the detection result of the regulation plate 5). It seems to be descending intermittently.

In this state, the counting result of the counting sensor 6 indicates that, for example, 50 coins, 40 coins, 20 coins, etc. corresponding to the number of wrapped coins are accumulated on the shelves 7. If the judgment is made based on this, the supply of coins from the coin passage 1 to the shelves 7, 7 is stopped, and the shelves 7, 7 are continuously lowered by a certain distance, and the accumulated coins are further lowered. It is designed to be delivered onto a shutter 10 (described later) located thereon.

Note that the lowering of the shelves 7, 7 as the stacking drums 2, 2 rotate is performed by a drive mechanism 8, which will be described later.

On the other hand, below the stacking drums 2, 2, the stacking section 3
A shutter 10 in which a certain number of coins are placed.
is provided.

This shutter 10 consists of shutter plates 11 and 12 respectively provided around shafts 11A and 12A, and a solenoid that rotates these shutter plates 11 and 12 in the direction of arrow mark and the direction of arrow E through link arms 13A' and 13B, respectively. SS, and the lower end of the stacking section 4 is opened by rotating the shirt shirt plates 11 and 12 in the direction of the arrow DE.

When the lower end of this stacking section 4 is opened, the coins accumulated on the shirt top plates 11 and 12 fall, and the supporting member ( (as shown). This support member is configured to move up and down at a constant cycle by a cam mechanism (not shown), and receives the accumulated coins on the shirt shirt plates 11 and 12 at the raised position, and receives the coins accumulated on the shirt shirt plates 11 and 12 at the lowered position. The received stack of coins is placed in a wrapping mechanism (as shown) and wrapped with wrapping paper.

Next, the drive mechanism 8 for driving the stacking drums 2 will be explained. This drive mechanism 8 includes an integrated motor 14 that is a stepping motor, and a plurality of gears 15A to 15E that are provided between the output shaft of this integrated motor 14 and the integrated drums 2, 2. The power output from the output shaft of 14 is transmitted to multiple gears 15A-15E.
It is configured to be transmitted to the collecting drums 2 through 2.

Further, the output shaft of the integrated motor 14 is provided with a rotating plate 16 (rotating body) having one slit (as shown in the figure) as a detection point on its peripheral edge, and near the periphery of this rotating plate 16, A deceleration position detection sensor 17 and a fixed position detection sensor 18 are respectively provided to detect that the slit has passed.

The deceleration position detection sensor 17 and the fixed position detection sensor 18 detect when the accumulated coins have reached the deceleration position and the fixed position when the predetermined number of coins stacked at the upper position of the stacking section 4 are continuously lowered. are detected, and the speed of the integrated motor 14 can be adjusted based on these detection results.

Note that the fixed position detected by the fixed position detection sensor 18 is a position where the shelf 7φ7 on which the accumulated coins are placed transfers the accumulated coins to the shutter 10, and This is a position where new coins can be accumulated relative to the upper position of No. 7 (indicated by symbols 7B and 7B). Ma I;,
The deceleration position detected by the deceleration position detection sensor 17 is between the position of the shelves 7, 7 when coin accumulation is completed and the normal position, and is near above the normal position. .

Control of the integrated motor 14 based on the daily outputs of the deceleration position detection sensor 17 and the fixed position detection sensor will be described later with reference to FIGS. 4 and 5.

Although not shown in FIGS. 1 to 3, the stacking drums 2, 2 are provided with a spacing adjustment mechanism for adjusting the spacing between the stacking drums 2, 2.

This interval adjustment mechanism supports the stacking drums 2, 2,
In addition, the shafts 15b and 15b are the rotation centers of the gears 15B and 15D.
15c, and a moving mechanism (as shown) that moves the frame so that the stacking drums 2 and 2 are moved closer to each other. By spacing the drums 2 and 2 close to each other, coins of a plurality of denominations having different diameters can be stacked in the stacking section 4.

Next, a control device for controlling the accumulating motor 14 of the coin accumulating device shown in FIGS. 1 to 3 will be described with reference to the block diagram of FIG. 4.

This block diagram, as shown in FIG. It is composed of a pulse output section 26, a packaging machine lateral control section 27, a shutter control section 28, a clear operation section 29, a shutter solenoid SS1 integrated motor 14, a deceleration position detection sensor 17, and a fixed position detection sensor 18. Various signals (a) to (1)) are output from these components.

The above components will be explained in order.

[-] The opening start/stop instruction section 0 gives instructions to start and stop the coin accumulation process in the accumulation section 4, and the start/stop instruction section 20 issues instructions to the conveyance control section 21. A start/stop signal (a) indicating the instruction content is output.

[2] The conveyance control unit 21 controls the driving of the rotating disk that supplies coins to the stacking unit 4, the driving of the conveying bell 1-IB, and the protrusion and retraction of the stopper. The coins conveyed on the passage 1 are detected by a counting sensor 6 serving as a number counting section 22 .

[3] The number counting unit 22 counts the coins each time the counting sensor 6 detects the coins, and
Number counting signals (b) and (c) indicating this counted value are outputted to the integration pulse output section 23 and the number comparing section 24, respectively.

Further, a clear signal (T) for clearing the counted value and a next count signal (T) are inputted to the sheet number counting section 22 from the clear operation section 29 and the packaging mechanism control section 27, respectively. (described later).

[4] The accumulation pulse output section 23 outputs a drive pulse signal (d) for driving the accumulation motor 14 every time the sheet count signal (b) output from the sheet number counting section 22 is input. Further, the driving speed of the integrated motor 14 is determined according to the output interval of this driving pulse signal (d).

Incidentally, since the counting of coins by the number counting section 22 is usually performed intermittently at a constant cycle, the accumulating motor 14 linked to the counting cycle is also driven intermittently at a constant cycle. There is.

In addition, if the stacking unit 4 wants to accumulate coins that have reached the number of wrapped coins (based on the output from the number comparison unit 24, which will be described later), the conveyance control unit 21 stops the conveyance of the coins. At the same time, the output of the sheet number counting signal (b) from the sheet number counting section 22 and the driving pulse signal (d) from the integration pulse output section 23 is stopped.

[5] The number comparing section 24 calculates a number of sheets counted based on the number counting signal (c) outputted from the number counting section 22 and a setting value based on the number setting signal (e) outputted from the number setting section 25. Specifically, it is compared with
It is compared to determine whether the number of coins counted by the number counting section 22 has reached the number of coins packaged by the number setting section 25 or not.

In addition, in the number setting section 25, as the packaging number of coins, in addition to 50 Japanese coins, 40 American coins, 20 American coins, etc. are set.

If the sheet number comparison section 24 determines that the sheet count value matches the packaging sheet value, the conveyance control section 21, the acceleration/deceleration pulse output section 26, and the packaging mechanism control section 27 agree. It is designed to output signals (f), (g), and (ch), respectively.

The coincidence signal (f) instructs the conveyance control unit 21 to stop driving the rotating disk and the conveyance belt IB, and to protrude a stopper for prohibiting the feeding of coins into the stacking unit 4. As a result, as mentioned above, the number of sheets count signal (b) from the sheet number counting section 22 is
, the output of the drive pulse (d) from the pulse output section 23 during integration is stopped.

The coincidence signal (g) instructs the acceleration/deceleration pulse output unit 26 to output an acceleration signal (su) (described later), and the coincidence signal (h) instructs the packaging mechanism control unit to output an acceleration signal (su) (described later). 27 to start packaging the accumulated coins (described later).

[6] The acceleration/deceleration pulse output unit 26 drives the accumulation motor 14 at high speed based on the input of the -accomplishment signal (g), and causes the shelves 7 on which the accumulated coins are supported to descend at high speed. This outputs an acceleration signal. Also,
In addition to the coincidence signal (g), a deceleration position detection signal (nu) and a fixed position detection signal (l) are input to this acceleration/deceleration pulse output section 26. In addition to the acceleration signal (su), a deceleration signal (wa) is output.

The deceleration position detection signal (nu) is generated by the deceleration position detection sensor 1.
It is output when the slit of the rotary plate 16 indicating the deceleration position is detected by 7, and the acceleration/deceleration pulse output section 26 outputs the deceleration position detection signal (nu) based on this deceleration position detection signal (nu).
A deceleration signal (wa) is output to the integrated motor 14.

The deceleration signal (wa) drives the accumulating motor 14 at low speed to lower the shelves 7 on which the accumulated coins are supported at a low speed. On the condition that (W) is input, the output of the above-mentioned acceleration signal (S) is stopped.

The fixed position detection signal (L) is output when the fixed position detection sensor 18 detects a slit in the rotary plate 16 indicating the fixed position, and is output from the acceleration/deceleration pulse output section 2.
6, the output of the deceleration signal (W) is stopped at the same time as the fixed position detection signal (L) is input, thereby stopping the lowering of the shelves 7.

[7] The packaging mechanism control unit 27 to which the coincidence signal (h) from the sheet number comparison unit 24 is input will be described.

This packaging mechanism control section 27 operates the packaging mechanism based on the coincidence signal (H), and also sends a reception timing signal (force) from this packaging mechanism control section 27 to the shutter control section 28. , the next count signal (y) are outputted, and the next count signal (event) is outputted to the sheet number counting section 22 described above.

The receiving timing signal (force) is output when the supporting member for receiving the accumulated coins on the shutter 10 is raised to a position directly below the shutter 10, and is outputted from the receiving timing signal (force). (event) is output when the shutter 10 is in the open state and the transfer of the accumulated coins to the support member is completed.In other words, there are no coins on the shutter 10 and the next coin is not available in the stacking section 4. This shows that integration processing is possible.

The next count signal (evening) is output to the sheet number counting section 22 as a clear signal for clearing the count value counted by the sheet number counting section 22.

[8] The shutter control unit 28 receives the above-mentioned reception timing signal (force) and next count signal (y), and
The fixed position detection signal output from the fixed position detection sensor 18 (
(w), a clear signal (n) output from the clear operation unit 29 (described later) is input, and this shutter control g628 also sends a signal to the shutter solenoid SS to open the shutter 10. Shutter signal (
) is now output.

The output conditions (+) and (ii) of the shutter signal (y) will be explained in order.

(i) When both the fixed position signal (wo) and the receiving timing signal (force) are input, a shutter signal (shutter signal) is used to open the shutter 10 in order to transfer the accumulated coins to the supporting member. ) is output.

(ii) If the clear signal (n) is input, the home position signal () is input after the clear signal (n) is input.
) is input, and if a reception timing signal (force) is input, the reception timing signal (force)
Since the upper surface of the shutter 10 is not used for placing the accumulated coins from when is input to when the next count signal (y) is input, the shutter 10 is not used to keep the shank 10 open. Outputs a signal. In addition, the above (■)
While the shutter 10 is in the open state as indicated by , it is preferable to allow the coins to fall downward and be removed, for example, in the event that a coin stacking error occurs in the stacking section 4 .

[9] The clear operation section 29 is for stopping the coin accumulation process in the accumulation section 4, and from this clear operation section 29, the coin counting section 22, the acceleration/deceleration pulse output section 26, and the shutter control section Clear signals (T), (N), and (N) for instructing 28 to stop the integration process are output at the same time.

The clear signal (T) is sent to the sheet number counting section 2 as described above.
This clears the count value of 2 and instructs the conveyance control section 21 to stop stacking coins in the stacking section 4 through the number comparison section 24.

The clear signal (N) sends and places the accumulated coins on the shelves 7, 7, on which coin feeding has been stopped, onto the shutter 10; the output of the acceleration signal (S) is a pulse output during acceleration/deceleration This is an instruction to the section 26.

Note that after this acceleration signal (S) is output, as described above, the deceleration position detection signal (N) and the home position detection signal (N) from the deceleration position detection sensor 17 and the home position detection sensor 18 are output.
The integrated motor 14 is continuously decelerated and stopped based on (b) and (b).

The clear signal (S) is sent to the shutter 10 as described above.
The coins accumulated on the shutter 10 are guided to the wrapping mechanism below.

Next, the main flow of each signal shown in the above block diagram will be explained with reference to chart 70 in FIG. Note that step n shown in the following description corresponds to SPn in FIG. 5.

It is determined whether a clear signal (N) has been input to
In the case of YES, the process returns to the original step 2, and in the case of YES, the process proceeds to the next step 5.

<Step 5> An acceleration signal (su) is output from the acceleration/deceleration pulse output unit 26 to the integrated motor 14.

Step 13> end.

As explained above, according to the coin stacking device shown in the first embodiment, when the number of coins accumulated on the shelves 7, 7 reaches the number of wrapped coins (step 4), the shelves 7, 7 are moved at high speed. Lower it (
Steps 5 to 6), and then, when the shelves 7 and 7 reach the deceleration position, lower the shelves at a low speed (Steps 7 to 9).
), furthermore, after this, the descent of the shelves 7 is stopped when they reach the home position (steps 10 to 12), so that the integrated motor 14 is prevented from stepping out. Therefore, the accumulated coins can be transferred onto the shutter 10 reliably and in a short time, and the upper and lower portions of the shelf sections 7, 7 can be adjusted when new coins are to be accumulated on the shelves 7, 7 in succession. It is possible to easily position the coins with respect to the coins, and it is possible to improve the workability of accumulating coins.

Next, a second embodiment of the present invention will be described with reference to FIGS. 6 and 7 (corresponding to claims 1 and 3).

Note that the deceleration position and normal position shown in this second embodiment are the same as the first
It is used in the same meaning as the deceleration position and normal position shown in the embodiment.

The coin stacking device shown in these figures differs in configuration from the drive mechanism of the stacking motor in the coin stacking device shown in the first embodiment. (not shown) is provided, a detection sensor 30 and a fixed position detection section 31 are provided for determining the driving speed of the integrated motor 14, and the outputs of these detection sensors 30 and fixed position detection section 32 are Based on this, an acceleration/deceleration pulse output section 32 for controlling the integrated motor 14 is provided.

The rotating plate, the detection sensor 30, the fixed position detecting section 31, and the acceleration/deceleration pulse output section 32 will be explained in order.The rotating plate has two slits (not shown) formed therein, unlike the rotating plate 16 of the first embodiment. A detection sensor 30 for detecting the slit is arranged around this rotary plate.

The detection sensor 30 detects the deceleration position of the integrated motor 14 driven at high speed by detecting the first slit (first detection point). When the slit is detected, a first detection signal (2) corresponding to the deceleration position detection signal (N) of the first embodiment is output to the acceleration/deceleration pulse output section 32.

The acceleration/deceleration pulse output section 32 stops outputting the acceleration signal (su) that has been outputted up to now, on the condition that the first detection signal (2) is input, and ), deceleration signals ■ and ■ for decelerating the integrated motor 14 are output to the integrated motor 14 and the fixed position detection section 31, respectively (the output condition of the acceleration signal (S) is the first Same as Example).

The fixed position detection section 31 generates a second detection signal ■ indicating that the detection sensor 30 has detected the second slit (second detection point) after a certain period of time after the deceleration signal ■ is input.
When inputted, a stop signal {circle around (2)} corresponding to the fixed position detection signals (l) and (w) of the first embodiment is output to the acceleration/deceleration pulse output section 32. This stop signal (■) is a deceleration signal (■) from the acceleration/deceleration pulse output section 32.
The output of signal (2) is stopped to improve the driving of the accumulation motor 14, and the output of this stop signal (2) causes the accumulated coins to be placed on the shutter 10 at a fixed position.

Note that the fixed position detection section 31 outputs a stop signal ■ to the acceleration/deceleration pulse output section 32 when the second detection signal ■ is input after a certain period of time has passed after the deceleration signal ■ has been input. However, if the second detection signal ■ is not input after a certain period of time, the shelves 7 and 7
It outputs a re-acceleration signal ■ assuming that it has passed the fixed position.

Specifically, before the deceleration signal ■ is input, a situation such as a jam or a power outage that prevents the accumulation process from continuing occurs.
- If the power is turned on again to continue the accumulation process after the power has been turned off (turned off), the weight of the coins may be artificially changed while the power is off. The accumulation drums 2, 2 may rotate in a direction that lowers the shelves 7, 7 due to the application of a Sometimes it happens. As a result, after the power is turned on from OFF, the first slit that should be detected next is not detected, and instead the second slit is determined to be the first slit, and the deceleration signal , ■ will be output.

However, at this point, it has already passed the fixed position,
The second slit is not detected within a certain period of time, and therefore, the second detection signal (2), which is the detection result of the second slit, is not input to the fixed position detection section 31.

On the other hand, after the deceleration signal ■ is input, in the same manner as above,
If the second slit passes through without being detected by the detection sensor 30, the second slit will naturally not be detected within a certain period of time after the power is turned on, and the second detection signal It is never entered.

If the second detection signal (■) is not input to the above-described fixed position detection unit 31 after a certain period of time has elapsed, it is assumed that the shelves 7 have passed the fixed position, and the force I7 deceleration pulse is output. The re-acceleration signal ■ is output to the output section 32, and the acceleration/deceleration pulse output section 32 outputs an acceleration signal (su) to the integrated motor 14 based on the re-acceleration signal ■.
is output, and the alignment of the shelves 7, 7 to their regular positions is performed again.

That is, the detection signal ■ output from the detection sensor 30,
Although the signal (■) itself does not distinguish between the first detection signal (■) and the second detection signal (■), the fixed position detection section 31 detects when the deceleration signal (■) is not input. The signal is determined to be the first detection signal ■, and the input of the detection signal within a certain period of time after the deceleration signal ■ is input is determined to be the input of the second detection signal ■, and the above-mentioned stop signal ■ or re-acceleration signal is determined. ■It is configured to output.

Next, the main flow of signals in the block diagram shown in FIG. 6 mentioned above will be explained with reference to the flowchart in FIG. 7.

Steps 21 to 26 are the same as steps 1 to 6 in FIG. 4, so their explanation will be omitted.

Step 27> It is determined whether the first detection signal ■ indicating that the detection sensor 30 has detected the first slit is output to the acceleration/deceleration pulse output section 26, and if NO, Return to the original step 26, and if YES, proceed to step 28.

<Step 28> to <Step 29> The acceleration/deceleration pulse output unit 26 outputs deceleration signals ■ and ■ to the integrated motor 14 and the fixed position detection unit 31, and further,
Based on the deceleration signal ■, the integrated motor 14 is driven to decelerate.

<Step 30>~Step 31> After the deceleration signal ■ shown in step 28 is input to the fixed position detection section 31, the detection sensor 30 is input to the identification position detection section 31 within a certain period of time. It is determined whether or not the second detection signal (■) indicating that the slit has been detected is input, and if NO (corresponding to YES in step 31), the process returns to step 25 and the addition from the identification position detection unit 31 is performed. A re-acceleration signal ■ for re-accelerating the integrated motor 14 is output to the deceleration pulse output unit 32, and if YES (
(corresponding to YES in step 30), the process advances to step 32, and the pulse output unit 32 outputs the acceleration/deceleration pulse from the identification position detection unit 31.
The stop signal for stopping the integrated motor 14 is
Output.

As explained above, according to the coin stacking device shown in the 942 embodiment, it is possible to obtain the same effects as the coin stacking device shown in the first embodiment, and the fixed position detection unit 31
After the deceleration signal ■ is input to the
If a situation arises in which the detection signal ■ cannot be input, the re-acceleration signal ■ is output to the acceleration/deceleration pulse output unit 32, assuming that the shelves 7 have passed the normal position, and the shelves are re-inputted. 7. Since I aligned it to the fixed position of 7,
When the power is turned on after the power is restored or after the jam is removed, it is possible to smoothly continue the coin accumulation process.

The coin stacking devices shown in the first and second embodiments are of a type in which coins are stacked by stacking drums 2, 2, but the present invention (claim 1) In addition to being applied to objects, as shown in Figure 8, a pair of belts 40, 40 are arranged at a certain distance from each other, and then a shelf 41, which is provided on these belts 40, 40, is used.
It can also be applied to a coin stacking device in which coins are stacked by lowering the coins 41 at the same height.

Specifically, by applying the present invention, the belts 40, 40
After stacking the number of coins to be packaged at the upper position of the stacking section 42 formed between them, the stacked coins are lowered at high speed to a deceleration position, and then, when the shelf sections 41 reach the deceleration position, the coins are The shelves 41, 41 are lowered at a low speed, and after this, when the shelves 41, 41 reach the home position, the shelves 41, 41 are lowered.
A configuration in which the descent of 41 is stopped is possible. However, it is assumed that a detection sensor (not shown) detects whether the shelves 41 have reached the deceleration position or the home position.

"Effects of the Invention" As explained in detail above, according to the first invention, when the accumulated coins on the edge reach the number of wrapped coins, the shelf is lowered at high speed, and then the shelf decelerates. When the shelf reaches the position, the shelf is lowered at a low speed, and furthermore, when the shelf reaches the fixed position, the shelf stops descending, so that the accumulated coins can be moved against the shelf. Not only can the coins be delivered reliably and in a short time, but also the vertical positioning of the shelf can be easily performed when new coins are continuously stacked on this shelf. It becomes possible to improve the workability of accumulation.

Further, according to the second and third inventions, the rotating body that operates in conjunction with the lowering of the shelf and the detection point of this rotating body are detected,
A detection sensor such as a deceleration position detection sensor or a fixed position detection sensor that indicates that the shelf has reached the deceleration position or the home position is provided, and the integrated motor is accelerated or decelerated according to the output of this detection sensor. This similarly prevents the accumulating motor from slipping out of synchronization, making it possible to reliably align the shelf portion to a regular position, thereby making it possible to improve the workability of accumulating coins.
