Abstract

PURPOSE: To minimize the useless drive of a pump motor by appropriately changing a rotary cylinder motor to low-speed torque at the time of judging that a suction shaft does not reach a start position or it passes through the start position and overruns. CONSTITUTION: When it is judged that the suction shaft 5 does not reach the start position or it passes through the start position and overruns, the low-speed torque of the rotary cylinder motor set in a rotary cylinder driving means 19 is appropriately changed. That is, since the low-speed torque of the rotary cylinder motor 19 is set into plural stages by a low-speed torque setting circuit 40, at the time of the movement to the start position N2 of the suction shaft 5 before starting a counting processing, when the low-speed torque of the rotary cylinder motor 19 is too large, it is set and changed smaller one stage. Also, when the low-speed torque of the rotary cylinder motor 19 is too small, it is set and changed larger one stage. Thus, the rotary cylinder motor 19 is driven by the optimum low-speed torque and the suction shaft 5 is surely moved to the start position N2 by the low-speed torque.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial illumination field" The present invention relates to a banknote counting machine that counts banknotes loaded in a holder by attracting them to a suction shaft on a rotating cylinder and flipping them one by one. It is.

"Prior art" Conventionally, this type of banknote counting machine was developed in Japanese Patent Application Laid-open No. 59-320.
1 shown in Publication No. 87 and Japanese Unexamined Patent Publication No. 1987-787
"Paper sheet counting machine" is known.

The old "paper sheet counting machine" set the suction shaft at the standby position (the position where the suction shaft is almost directly facing the paper sheets to be counted) with the holder 111, which is capable of loading paper sheets, placed in the holder 111 position. In addition, when the holder is in the closed position where paper sheets can be counted, the suction shaft is moved to the starting position (the position where the suction shaft is separated from the paper sheets to be counted in the reverse direction: the inside of the suction shaft is shut off and sealed from the outside). The suction shaft is moved from the standby position to the start position by a rotary cylinder motor.

The latter 1 paper sheet R1 @ machine - 1 paper sheet (banknote) loaded in the holder is attracted to the suction shaft - and the denomination is determined while turning over each sheet 7, and the denomination has been counted. If the denomination (Zunaitsushi) is - (equivalent to the denomination of 1) and -V (it is judged that there are two different denominations, and it is judged that it is impossible to distinguish the denomination), The turning-up operation using the suction shaft is interrupted, and during this interruption, banknotes judged to be of a different denomination or banknotes with an abnormality in identification (
Both banknotes (together referred to as abnormal banknotes) can be visually confirmed.

As a result of this confirmation, if it is determined that there is no abnormality in the operation panel, the interruption state of the flipping operation is canceled and counting of banknotes is continued.

[Problems to be Solved by the Invention] By the way, in the paper sheet counting machine shown in the previous paragraph, when aligning the suction shaft from the standby position to the start position, the rotary cylinder motor is operated at low speed (the suction shaft is rotated at low speed). On the other hand, if this low-speed torque is set strongly (tx), the suction shaft will exceed the starting position and overrun (17), or the rotation will occur. If the low-speed torque of the cylindrical motor is set to be weaker than necessary, the suction shaft will smoothly move from the standby position to the start position.1. There was a problem.

In addition, in the paper sheet counting machine described in 1-, when the suction shaft is placed on standby (position q) to the starting position (l), the pump motor for creating a vacuum pressure inside the suction shaft is simultaneously driven. However, on the other hand, if the suction shaft is not placed at the starting position due to the problem described in -1- and the inside of the suction shaft is not shut off and sealed from the outside, then the vacuum pressure will be −
Since L does not rise, the pump motor continues to be driven in vain during that time.

In addition, in the paper sheet counting machine shown in the latter type, when the sheet turning operation is interrupted and counting is continued from the 1-saw state, it is necessary to move the suction shaft to the starting position again as described above. be.

However, in this case, as shown by the symbol S in FIG. 6, if the number of paper sheets that have already been turned over and counted has increased, the bill S and the suction shaft (indicated by the symbol M) Due to the increased frictional resistance, the preset low-speed torque of the rotary cylinder motor cannot cope with the problem. I had one or two similar problems.

This invention was made in view of the above circumstances, and the torque of the rotary cylinder motor is changed depending on the situation to efficiently position the suction shaft at the starting position in a short period of time. Obtaining a counter is [1 objective].

[Means for Solving the Problem] In order to achieve this object, the present invention rotates the suction shafts evenly arranged on the concentric circles of the rotating cylinder at high speed in the normal direction.
71; In a banknote counting machine that adsorbs and counts banknotes loaded in a rudder one by one, a first
As shown in the functional block diagram in the figure, the suction shafts arranged evenly in the rotary cylinder are rotated forward or reversed with low-speed torque, and the suction shafts are placed in a standby position where they directly face the banknotes loaded in the holder. The rotary cylinder driving means (a) provided with a rotary cylinder motor that moves the banknote from the banknote to a starting position spaced from the banknote in the reverse direction, and the moeki suction shaft have moved from the standby position to the starting position. The rotating cylinder position detecting means (b) detects whether or not the rotating cylinder position detecting means (b) detects whether the rotating cylinder position detecting means (b) is A rotary cylinder position determination means (c) for determining whether the suction shaft has passed its starting position and overrun in the reverse rotation direction or forward rotation direction; and the inspection result of this rotary cylinder position determination means (c). Based on this, the rotary cylinder driving means is provided with a low-speed torque setting means (d) for appropriately changing the low-speed torque of the rotary cylinder motor set in the rotary cylinder driving means.

[Operation-1] According to the present invention, if it is determined that the suction shaft has not reached the starting position or that the suction shaft has overrun the starting position in the reverse direction or the forward direction, Based on this determination result, the low-speed torque of the rotary cylinder motor set in the rotary cylinder driving means is changed appropriately.
I'm 7.

In other words, without the rotating cylinder reaching the starting position 1q,
If it is determined that the low-speed torque of the L rotary cylinder motor is small, the rotary cylinder driving means sets the low-speed torque so that it is correct (2 corrections, and the rotary cylinder passes the starting position I7). If it is determined that the low-speed torque of the rotary cylinder motor by the rotary cylinder driving means is large due to overrun in the reverse rotation direction or forward rotation direction, the low-speed torque is reset to be small. , The suction shaft is moved to the starting position by the low speed !・lux whose setting is changed in this way.

On the other hand, if the suction shaft moves directly from the standby position to the start position due to an overrun or the like, as a result, the setting of the low-speed torque is not changed, so the rotary cylinder drive means The low-speed torque set to will be maintained as is.

[Example 1] Hereinafter, the present invention will be described based on an example not shown in FIGS. 2 to 5.

First, according to Figures 2 and 3, the banknote counting machine +
, q, this counting mechanism is constructed by placing banknotes S on holder 1 and horizontally rotating this holder 2 about shaft 2, so that it can be moved to the open position (not shown by the solid line in FIG. 2),
Alternatively, move the rotary cylinder 3 to the closed position 4 as shown by the chain line in Fig. 2, and when the holder 1 is in the closed position, rotate the rotating cylinder 3 counterclockwise in Fig. 2 about the axis 4. 3"
Rotate the second suction shaft 5 clockwise around the foot 6,
The basic structure is such that a vacuum pressure is applied to the suction shaft 5 and the banknotes S in the holder 1- are turned over one by one while counting is performed.

Note that when the holder 1 is in the open position, banknotes S can be loaded into and replaced with the holder 1.

The rotary cylinder 3 and the shaft 4.6 of the suction shaft 5 are formed in a hollow shape as shown in FIG. 3, and are connected to the suction boat 9 of the vacuum pump 8 via the suction pipe 7. The vacuum pressure of the vacuum pump 8 acts on the banknote S through the opening 10 provided on a part of the outer periphery of the suction shaft 5, so that the banknote S is attracted to the suction shaft 5. It looks like this. Further, a pressure sensor (
A pressure transducer (11) is provided, and this pressure sensor (11) detects whether the vacuum pressure in the suction pipe (7) has reached -F to an extent that can attract banknotes. .

On the other hand, an exhaust pipe line 13 is connected to the exhaust boat 12 of the vacuum pump 8.

Further, as shown in FIG. 2, a plurality of actuation pieces 17 made of magnetic material are attached to the outside/'il of the rotation n3, and these actuation pieces 17 act as magnetic sensors (rotating part position sensors) ( Depending on whether or not the rotary cylinder position detection means 18 is activated, each suction shaft 5 is set to the standby position (open [position where the first part 10 directly faces the bill and the inside of the suction shaft 5 is communicated with the vacuum pump 8: 2) or the starting position (the position immediately before the opening 10 faces the banknote,
In addition, it is detected whether or not the interior of the suction shaft 5 is at a position indicated by the symbol N in FIG.

In addition, in FIG. 3, the symbol I9 indicates the rotary cylinder 3.
A rotating cylinder motor (rotating cylinder driving means) that drives the vacuum pump 8 via the belt 20 (rotary cylinder driving means), and the one indicated by the reference numeral 21 connects the vacuum pump 8 to the belt 2? A pump motor, referenced 23, is driven via a holder motor, referenced 24, which rotates the holder l.
Reference numerals A and 24B indicate holder position detection switches that detect whether the holder 1 is in the closed position (close to the suction shaft 5) or in the open position (separated from the suction shaft 5).

Furthermore, a separator (not shown) is provided near the rotary cylinder 3. This separator is supported so that it can rotate horizontally, and it separates banknotes that have been inserted between banknotes and caused counting interruptions based on detection by an image sensor, double feed detection sensor, etc. (not shown). It is supposed to be done. In other words, based on the detection results of the image sensor,
When it is determined that the counted banknote is different from the denomination of the already counted banknote (i.e., corresponds to the -th denomination),
When it is determined that the denomination cannot be distinguished, and on the other hand, when it is determined that the suction shaft 5 has double-adsorbed banknotes based on the detection result of the double-feed detection sensor, the IFI separator operates, Separate uncounted banknotes from counted banknotes and abnormal banknotes (banknotes determined to be of a different denomination, banknotes with abnormal discrimination, and banknotes detected as double feeding are collectively referred to as abnormal banknotes), and visually check the operation name. There are some that are made to look like this.

As a result of this confirmation, if the operation panel indicates that there is no y4, the interruption of the flipping operation is canceled by operating a confirmation switch (described later), etc., and the counting of bills is continued. It is something.

Next, the counting control circuit 30 that operates the banknote counting mechanism will be explained with reference to FIG.

Of course, the counting control circuit 30 includes a counting control progera l for counting banknotes (rotating barrel motor 1 at the start of counting).

After the bill has been verified, there is a push 4-confirmation switch or the like to continue counting the bills.

On the other hand, 0;1 note! A rotating cylinder motor drive circuit (rotating cylinder driving means) 39 is connected to the boat 34 . This rotary cylinder motor drive circuit 39 drives the rotary cylinder motor 19.

After the start of counting is instructed (output of a start signal) (including a start in the middle when continuing), the rotary cylinder motor 19 is driven at low speed torque until the suction shaft 5 moves to the starting position and reaches the 4° position, and then , after the suction shaft 5 moves to the starting position,
The suction shaft 5 is driven with high-speed torque.

Note that the low-speed torque refers to the torque of the rotating cylinder motor 19 when positioning the suction shaft 5 to the starting position IN, and the high-speed torque refers to the torque of the rotating cylinder motor 19 when counting banknotes. It does not necessarily indicate the magnitude of strength.

Further, the rotary cylinder motor drive circuit 39 is connected to the rotary cylinder motor 1.
The conditions for switching the rotational torque of 9 from the low-speed torque for positioning to the high-speed torque for counting are such that the rotating part position sensor I8 detects that the suction shaft 5 has moved to the starting position, and the pressure conversion This is when the element II detects that the vacuum pressure within the suction shaft 5 has reached a predetermined value (details are shown in FIG. 5) (see section 4'' in the 1-chart below).

Further, a low speed torque setting circuit (low speed torque setting means) 40 is connected to the U 33 (CI) 07j.

This low-speed torque setting circuit 40 is connected to the rotary cylinder motor drive circuit 39, and is configured to set J and % to the output of the rotary cylinder position sensor 18, and
The low speed torque for driving 9 at low speed is applied to the motor drive circuit 39 in multiple stages! 4 is a setting thing. In other words, the low-speed torque setting circuit 40 is designed to step-by-step change the voltage at which the rotary cylinder motor 19 is driven at low speed with respect to the rotary cylinder motor drive circuit 39.

The low-speed torque, which is set in stages by the low-speed torque setting circuit 40, varies depending on the type of paper sheet (banknotes, bonds, lottery tickets, etc.) or the state of the vacuum pump 8, etc., depending on the overall level, l-, or It is possible to change the number of stages.

Next, count side m of banknotes written in ROM 31 in -

The steps will be explained with reference to the figures.

<Step 1> Rotation simple position control opening: When the counting start instructing mechanism 35 outputs a start signal instructing the counting start, the rotary cylinder motor drive circuit 39 drives the rotary cylinder motor 19 in the reverse direction 12, The suction shaft 5 placed at the standby position N1 is reversed in the direction indicated by arrow A (see Fig. 2), and the pump motor 21 is driven on the other hand to increase the vacuum pressure inside the suction shaft 5. As a result, positioning of the rotary cylinder 3 (suction shaft 5) is started.

<Step 2> Based on the output of the pressure conversion element 11, it is determined whether the vacuum pressure in the suction shaft 5 has reached a predetermined value, and if YES, proceed to step 3, and if bj #:, NO. If so, proceed to step 4.

<Step 3> When the vacuum pressure inside the suction shaft 5 reaches a predetermined value (the inside of the suction shaft 5 is cut off from the outside), the suction shaft 5 moves to the starting position N,
(If you proceed directly from step 1 to step 3), the rotary cylinder motor drive circuit 39 torques the rotary cylinder motor 19 at high speed and drives it in the forward direction.
The banknotes S are counted.

Step 4> The output of the rotary cylinder position sensor 18 is set to J, (and the suction shaft 5 (
It is determined 17 whether the rotary cylinder 3) has moved to the starting position N, and if the result is '/ES, the process returns to the original step 2, and if the result is no, the process proceeds to the next step 5.

Step 5> The rotary cylinder motor drive circuit 39 drives the rotary cylinder motor 19 in the reverse direction with low speed torque. Ru.

<Step 6> Rotating cylinder position sensor! Based on the protrusion of step 8, it is determined whether the suction shaft 5 (rotary cylinder 3) has moved to the starting position N, and if YES, proceed to step 9, and if NO, proceed to step 7. Proceed to.

<Step 7> to Step 8> Even if the rotary cylinder motor drive circuit 39 drives the rotary cylinder motor 19 at low speed torque for a certain period of time, the suction shaft 5
does not move to the starting position N, (step 6
~Step 7), the low speed torque setting circuit 40 changes the setting of the low speed torque of the rotary cylinder motor 19 to one that is one step stronger (Step 8).

Thereafter, the rotating cylinder motor drive circuit 39 drives the rotating cylinder motor 19 in the reverse direction according to the low speed torque set one step stronger by the low speed torque setting circuit 40.

<Step 9> to <Step 10> Once the suction shaft 5 has moved to the starting position N, the rotary cylinder motor drive circuit 39 stops driving the rotary cylinder motor 19 in the reverse direction (in the direction of the arrow). At the same time, the rotary cylinder motor 19 is braked for a certain period of time.

Step 11> Determine whether the suction shaft 5 has overrun past the starting position N, and if NO, return to the original step 2.
Moreover, in the case of YES, the process proceeds to the next step 12.

<Step 12> to Step 13> In order to return the overrun suction shaft 5 to the starting position Nt, the low speed torque setting circuit 40 increases the low speed l of the rotary cylinder motor 19.

If O, proceed to step 15.

<Step! 5>~〈Step 16〉 Similar to steps 7 to 8, over a certain period of time,
Even if the rotary cylinder motor drive circuit 39 drives the rotary cylinder motor 19 with a predetermined torque (for example, the torque set in step 8), if the suction shaft 5 does not move to the starting position N (step 14). -Step 15), the low-speed torque setting circuit 4O sets the low-speed torque of the rotary cylinder motor I9 to -

Step 20> In order to return the overrun suction shaft 5 to the starting position N, the low-speed torque setting circuit 40 changes the low-speed torque of the rotary cylinder motor 19 to one level weaker, and returns to the original step 5.
Return to

In the bill counting machine configured as described in 1-, the low-speed torque of the rotary cylinder motor 19 can be set in multiple stages by the low-speed torque setting circuit 40.
Before the start of the counting process (step 3), when moving the suction shaft 5 to the starting position N, if the low-speed torque of the rotary cylinder motor 19 is too strong, change the setting to a -step weaker torque. Step 12 and Step 20)
Also, if the low speed torque of the rotary cylinder motor I9 is too weak, the setting should be changed to one that is one step stronger (Step 8, Step 1G).

Therefore, in the bill counting machine described in -1-, the rotary cylinder motor 19 is driven with the optimum low-speed torque, and the suction shaft 5 is reliably moved to the starting position N by the low-speed torque. Therefore, the counting process starts (step 3
) Waiting for the vacuum pressure "-H" in the suction shaft 5 at line 0;1, it is possible to immediately shift to the counting process. In other words,
It is possible to minimize unnecessary driving of the pump motor 21.

Furthermore, since it is possible to arbitrarily change the setting of the low-speed torque of the rotary cylinder motor 19, even if counting is interrupted due to detection of different types of bills after the number of already counted bills increases as shown in FIG. The rotary cylinder 3 can be smoothly rotated in the direction of the arrow or in the direction of the arrow B, and the suction shaft 5 can be reliably moved to the starting position N. In other words, the suction shaft 5 is at the starting position N.

When moving the bill to the starting position Nt, the influence of friction caused by the sliding of the counted banknotes on the rotary tube 3 can be eliminated, and the suction shaft 5 can be reliably moved to the starting position Nt.

In the banknote counting machine described above, the low-speed torque of the rotary cylinder motor 19 is automatically changed and set by the low-speed torque setting circuit 40, but the output of the rotary cylinder position sensor 18 is not limited to this. The low-speed torque of the rotary cylinder motor 19 may be appropriately changed by the operator himself (according to the instructions from the CPU 33) by operating a knob or the like (low-speed torque setting circuit).

Furthermore, although the above bill counting machine is equipped with an image sensor, a sensor for detecting two-ton feed, etc., the installation of these sensors is optional.

[Effects of the Invention, 1. As explained in detail above, according to the present invention, the suction shaft does not reach the starting position until the suction shaft reaches the starting position, and the suction shaft does not move past the starting position to the reverse rotation direction or the forward rotation direction. If it is determined that overrun has occurred, the low-speed torque of the rotary cylinder motor set to the first stage of rotary cylinder drive is appropriately changed based on this determination result. In other words, if it is determined that the low-speed torque of the rotary cylinder motor by the rotary cylinder driving means is small without the suction shaft reaching the starting position, the low-speed torque is reset to be large; Further, if the rotary cylinder passes the starting position and overruns in the reverse rotation direction or the forward rotation direction and it is determined that the low speed torque of the suction shaft is large, the low speed l-
Change the setting to L, which is a small value.

Therefore, when using the two-leg banknote counter J5, the suction shaft is driven with the optimal low-speed torque whose settings are changed as appropriate, and the suction shaft is reliably positioned to the starting position by the low-speed torque. Therefore, H in the counting process
Waiting for the vacuum pressure within the suction shaft to rise at fl 8 direct, it is possible to immediately shift to the counting process. In other words,
It is possible to minimize unnecessary pump motor drive.

Furthermore, since it is possible to change the low-speed torque of the rotary cylinder motor set in the rotary cylinder driving means to any color, the counted banknotes do not slide against the rotary cylinder when the suction shaft is moved to the starting position. This has the effect that the suction shaft can be reliably moved to the starting position by eliminating the influence of friction caused by movement.
