  However, in the above-described conventional technology, the strength of heating of the pressing portion is a strength set in advance by an attendant, and thus the device itself cannot have a strength according to the surrounding environment. Depending on the temperature environment, there is a problem in that the adhesiveness of the tape wound around the banknote bundle varies depending on the temperature environment, for example, if the heating of the pressing portion is weak, the adhesiveness of the pressed tape becomes weak.

And a storage means for detecting a temperature rise rate of the heater section corresponding to the temperature around the heater section and a temperature required for the heat bonding of the heater section. When the heating of the heater unit is started, the temperature increase rate is calculated from the temperature detected by the detection unit, the temperature around the heater unit corresponding to the temperature increase rate is read from the storage unit, and the heater unit The temperature required for the thermal bonding corresponding to the ambient temperature is read, and the heater unit is heated until the temperature required for the read thermal bonding is reached.

A state is shown when heating by the heater 22 is performed until

The graphs 51, 52, and 53 have a relationship of 51>52> 53 when arranged in the order of the ambient temperature.
The temperature rise rate can be shown by the slopes of the respective graphs 51, 52, 53 of FIG. 5. When the ambient temperature is high as shown in FIG. 5, the temperature rise rate becomes larger from the slope shown in the graph 51, and the ambient temperature When is small, it is clear from the slope shown in the graph 53 that the rate of temperature increase is small.

Here, the operation | movement at the time of winding the tape 2 around a banknote bundle is demonstrated.

The following operations are operations executed by the control of each unit performed by the control unit 25.
6A and 6B are explanatory views showing a state in which the tape is clamped by the clamping member. FIG. 6A shows a state immediately before the tape is clamped, and FIG. 6B shows a state in which the tape is clamped.
When the tape 2 is supplied along the feed path by the supply roller unit 3, the leading end of the tape 2 is sandwiched between the guide roller unit 5 and the leading end of the tape 2 is further rotated by the rotation of the guide roller unit 5. 11 is sent.

  At this time, the tape winding unit 11 rotates only the clamping member 12 from the position where both the clamping members 12 and 13 descend downward, as shown in FIG. When the leading end of the tape 2 enters between the sandwiching members 12 and 13 while waiting in the open state, the sandwiching members 12 and 13 are shown in FIG. Then, the front end of the tape 2 is clamped.

Subsequently, while supplying the tape 2 by the supply roller unit 3, the clamping members 12 and 13 are rotated approximately half a clockwise direction (in the direction of arrow B in FIG. 2), that is, approximately 180 degrees, whereby the tape 2 is described later. The transport path when the bundle is transported is blocked.
FIG. 7 is an explanatory view showing a state when a banknote bundle has been sent, and FIG. 8 is an explanatory view showing a state when the conveyance of the banknote bundle is stopped.

When a banknote bundle is fed between the lower conveyor belt 8 and the upper conveyor belt 9 by means not shown, the upper conveyor belt 9 rotates downwardly as indicated by an arrow C around the fulcrum roller 10 as shown in FIG. By doing so, a banknote bundle is pinched between the lower conveyance belt 8.
Thereafter, the lower conveyor belt 8 and the upper conveyor belt 9 are rotated by driving a drive source (not shown), and the banknote bundle is conveyed in the direction of arrow D shown in FIG. At that time, the banknote bundle pushes in the tape 2 that blocks the conveyance path at the front end, and at this time, the tape 2 is supplied by the rotation of the rollers 3a to 3d of the supply roller unit 3, so that the tape 2 is It is pulled out to cover.

When it is detected by a position confirmation sensor (not shown) that the banknote bundle to be conveyed has reached a predetermined position, a state as shown in FIG. 8 is obtained, and the lower conveyor belt 8 and the upper conveyor belt 9 stop conveying the banknote bundle.
Subsequently, while the tape 2 is supplied by the rotation of the rollers 3a to 3c, when the tape winding part 11 is rotated so that the holding members 12 and 13 are rotated by the other half in the clockwise direction, the tape is held by the tape winding part 11. The tape 2 crosses the conveyance path on the rear end side of the banknote bundle from above the rear end of the banknote bundle and wraps around the rear end of the banknote bundle.

FIG. 9 is an explanatory view showing a state where a tape is wound around a banknote bundle.
As a result, the rear end portion of the banknote bundle is surrounded by the tape 2, and then the banknote is entered by driving the lower transport belt 8 and the upper transport belt 9 by a driving source (not shown) while feeding the tape 2 by the supply roller section 3. If it rotates so that it may convey in the opposite direction, it will be in the state which wound the tape 2 around the banknote bundle as shown in FIG. 9, and winds the tape 2 around the banknote bundle by such a method.

And the heater part 20 is raised, the glue applied to the tape 2 is melted by pressing the heater block 21 for about 1 second from below the overlapping part of the tape 2, and the tape 2 is thermally bonded.
The operation of the heater unit in the above-described configuration, particularly the operation when heating by the heater 22 is started will be described.

The controller 25 performs heating by the heater 22 before performing the process of winding the tape 2 around the banknote bundle, for example, immediately after the power is turned on to the medium binding device, so that the heater block 21 is necessary for bonding the tapes 2 to each other. The heating time until the temperature rises is measured, the temperature increase rate based on the measured heating time is calculated, and the calculated temperature increase rate is stored in the storage unit 26.
Calculation of the rate of temperature increase by the control unit 25 will be described below based on the graph 52 of FIG.

The control unit 25 measures the heating time t1 required from a certain temperature T0 to the set temperature T1 required for bonding the tapes 2 to each other, and the temperature increase rate at that time is from T0 to T1 in the graph 52 of FIG. Since the inclination is a, the inclination a is
a = (T1-T0) / t1
It can be calculated by

The control unit 25 stores the gradient a calculated as described above, that is, the temperature increase rate in the storage unit 26 and searches a table of temperature increase rates stored based on the temperature increase rate, Identify the ambient temperature corresponding to the rate of temperature rise.
Based on the specified ambient temperature, the control unit 25 uses a table indicating the relationship between the optimum temperature and the ambient temperature to melt the adhesive adhered to the tape 2 stored in the storage unit 26, and at the corresponding ambient temperature. The temperature necessary for heat bonding is read out, and the heater block 21 is heated by the heater 22 until the read temperature is reached.

As described above, in this embodiment, the ambient temperature is specified based on the rate of temperature rise of the heater block after the heating by the heater is started, and the tape paste is melted corresponding to the ambient temperature to heat Since the heater block is heated to a temperature necessary for bonding, the tape can be stably bonded so as to follow the change in the ambient temperature.
In addition, it is necessary to provide at least a temperature detection unit in the conventional configuration, and the effect of the present embodiment can be obtained with substantially the same configuration as the conventional configuration, so that it can be realized at low cost.

  In the first embodiment, the temperature increase rate is calculated from a certain temperature T0 to the set temperature T1 based on the time t1, but the temperature increase rate is calculated from a more instantaneous temperature change and the time. May be.

The medium bundling apparatus according to the present embodiment has the same configuration as that of the first embodiment, but is different in that it is an operation for specifying the ambient temperature when the heater unit 20 is controlled at a constant temperature.
Here, the control unit 25 that performs constant temperature control repeatedly heats and stops heating the heater 22 of the heater unit 20 at predetermined intervals every predetermined time (for example, 1 second), and sets the temperature at which the heater block 21 is set in advance. I try to keep it.

At this time, the control unit 25 detects the temperature of the heater block 21 by the temperature detection unit 23, and an intermediate temperature between the temperature when the heating is stopped and the temperature when the heating is started is the constant temperature control. It is assumed that the heating intensity of the heater 22 is adjusted so that the temperature is set in advance.
FIG. 10 is an explanatory diagram showing the relationship between temperature and time during constant temperature control in the second embodiment.

Graphs 61, 62, and 63 shown in FIG. 10 show changes in the temperature of the heater block 21 during constant temperature control.
The graphs 61, 62, and 63 have a relation of 61>62> 63 when arranged in order of the ambient temperature.
As shown in FIG. 10, in the constant temperature control, the vertical width of the temperature of the heater block 21 due to the heating by the heater 22 and the stop of the heating, that is, the amplitude of each of the graphs 61, 62, 63 varies depending on the ambient temperature.

Comparing the amplitude δTH of the graph 61 with the amplitude δT of the graph 62, it is clear that the amplitude δTH <the amplitude δT as shown in FIG. 10, and comparing the amplitude δT of the graph 62 with the amplitude δTL of the graph 63, As shown in FIG. 10, it is clear that amplitude δT <amplitude δTL.
Thus, it is clear that the amplitude is larger when the ambient temperature is lower than when the ambient temperature is high. Therefore, the storage unit 26 of the present embodiment stores a table indicating the relationship between the amplitude of the constant temperature control and the ambient temperature, which is configured by the amplitude of the constant temperature control for each ambient temperature in advance.

During the execution of the constant temperature control, the control unit 25 detects the maximum and minimum values of the temperature of the heater block 21 that rises and falls during the constant temperature control by the temperature detection unit 23, and the maximum and minimum values are detected. And the above-mentioned amplitude is calculated.
The control unit 25 recognizes the ambient temperature by reading the ambient temperature of the corresponding amplitude from the table indicating the relationship between the constant temperature control amplitude and the ambient temperature stored in the storage unit 26 based on the calculated amplitude. To do.

The control unit 25 recognizes the ambient temperature from the table indicating the relationship between the temperature necessary for melting and bonding the adhesive adhering to the tape 2 of Example 1 stored in the storage unit 26 and thermal bonding. The heater 22 is heated so that the optimum temperature is read and the heater block 21 reads the temperature.
As described above, in this embodiment, in addition to the effects of the first embodiment, the temperature of the heater block 21 is adjusted during the constant temperature control so that the temperature becomes the temperature required for thermal bonding with respect to the ambient temperature at that time. Since the heater is heated, the tape to be wound around the banknote bundle conveyed during the constant temperature control can be stably adhered.

The medium bundling apparatus according to the present embodiment has the same configuration as that of the first embodiment, but is different in that it is an operation for specifying the ambient temperature when the heater unit 20 is controlled at a constant temperature.
Here, the control unit 25 that performs the constant temperature control determines an upper limit temperature and a lower limit temperature that use a preset temperature of the constant temperature control of the heater block 21 as a center temperature, and heats it until the upper limit temperature is reached, When the temperature reaches the upper limit temperature, the heating is stopped, and when the temperature falls to the lower limit temperature, the process of heating to the upper limit temperature is repeated.

FIG. 11 is an explanatory diagram showing the relationship between temperature and time during constant temperature control in the third embodiment.
Graphs 71, 72, and 73 shown in FIG. 11 show changes in the temperature of the heater block 21 during constant temperature control, and graphs 71, 72, and 73 are 71>72> 73 when arranged in order of the ambient temperature. It has become a relationship.
Here, when heating of the heater 22 is started, the heating is stopped, and heating is started again as one cycle, the time for one cycle is set to one cycle in the graph 71 as shown in FIG. When this time is represented as δtH, the time taken for one cycle in the graph 72 as δt, and the time taken for one cycle in the graph 73 as δtL, δt is longer than δtH and δtL is longer than δt. 11 is clear.

Thus, it is clear that the time taken for one cycle is longer when the ambient temperature is lower than when the ambient temperature is high. Therefore, the storage unit 26 of the present embodiment stores a table indicating the relationship between the time of one cycle and the ambient temperature, which is an actual measurement value of the time taken for one cycle in the constant temperature control for each ambient temperature.
During the execution of the constant temperature control, the control unit 25 measures the time required for one cycle by a clock function (not shown), and stores the one cycle stored in the storage unit 26 based on the measured time. The current ambient temperature is recognized by reading out the corresponding ambient temperature from the table indicating the relationship between time and ambient temperature.

  The control unit 25 is optimal for the recognized ambient temperature from the table showing the relationship between the optimum temperature and the ambient temperature for melting the glue attached to the tape 2 of the first embodiment stored in the storage unit 26. The temperature is read out, the optimum temperature is set as the set temperature in the above-described constant temperature control, and the setting is changed, and the heater 22 is heated so that the heater block 21 becomes the set temperature.

  As described above, in this embodiment, in addition to the effects of the first embodiment, the temperature of the heater block 21 is adjusted during the constant temperature control so that the temperature becomes the temperature required for thermal bonding with respect to the ambient temperature at that time. Since the heater portion is heated, the tape can be stably adhered so as to follow the change in the ambient temperature. Adhesion of the tape wound around the banknote bundle conveyed at the time of constant temperature control can be performed stably.

The configuration of the present embodiment is the same as that of the third embodiment, but the third embodiment recognizes the ambient temperature based on the time required for one cycle, whereas the upper limit temperature and the lower limit temperature are set in the constant temperature control. The difference is that the ambient temperature is recognized based on the temperature change between the two.
FIG. 12 is an explanatory diagram showing the relationship between temperature and time during constant temperature control in the fourth embodiment.
The constant temperature control of the fourth embodiment is the same as the control in the third embodiment.

Here, for example, when calculating the slope of the temperature change that increases or decreases during the constant temperature control from the graph 72 of FIG. 12, if the time t2 from the time t1 reaching the upper limit temperature Tx1 to the lower limit temperature Tx2 is used, The rate of change a is
a = (Tx1-Tx2) / (t2-t1)
Can be expressed as

  Here, the part of (Tx1-Tx2) in the equation for calculating the rate of change a is a determined value because it is the difference between the upper limit temperature and the lower limit temperature as described above, but the part of (t2-t1) is The time interval between the upper limit temperature and the lower limit temperature is different depending on the ambient temperature as shown in FIG. 12. When the ambient temperature is high, the interval is short as shown in the graph 71, whereas the ambient temperature is low. In this case, the interval becomes longer as can be seen from the graph 73.

Therefore, it is clear that the rate of change in temperature increases when the ambient temperature is high, but decreases when the ambient temperature is low.
Utilizing this, the storage unit 26 of the present embodiment has a table showing the relationship between the temperature change rate and the ambient temperature, which includes the ambient temperature and the rate of temperature change in the constant temperature control according to each ambient temperature. Stored.

The control unit 25 measures the time from the detection of the upper limit temperature by the temperature detection unit 23 to the detection of the lower limit temperature during the execution of the constant temperature control, and the measured time, upper limit temperature, and lower limit. The temperature change rate is calculated and specified using the temperature.
And the control part 25 reads the applicable atmospheric temperature from the table which shows the relationship between the ratio of the temperature change memorize | stored in the memory | storage part 26 based on the calculated rate of temperature change, and atmospheric temperature, and is present. Recognize the ambient temperature.

  As described above, the present embodiment recognizes the ambient temperature based on the rate of temperature change from the upper limit temperature to the lower limit temperature during execution of the constant temperature control, and thus obtains the same effect as the third embodiment. be able to.

The configuration of this embodiment is the same as that of each of the embodiments described above, except that the time for pressing the heater unit 20 against the tape 2 is changed according to the ambient temperature.
The memory | storage part 26 of a present Example stores the table regarding the press time of the tape 2 by the heater part 20 for every atmospheric temperature.
The pressing time by this table is, for example, 1 second when the ambient temperature is 30 ° C. or lower and within the range of 25 ° C. or higher, and when the ambient temperature is lower than 25 ° C. and 10 ° C. or higher. Is determined to be 1.3 seconds or the like.

When the control unit 25 presses the tape 2 wound around the banknote bundle with the heater unit 20 as in the first embodiment, the storage unit 26 stores the pressing time according to the ambient temperature specified from the temperature increase rate at that time. The tape 2 is pressed by the heater unit 20 in accordance with the pressing time.
Moreover, the control part 25 reads the press time according to the atmospheric temperature specified by the method shown in the said Example 2, 3, 4 in the case of constant temperature control, and it is banknote while performing constant temperature control. When the bundle has been conveyed, the tape 2 is wound around the banknote bundle and the tape 2 is pressed by the heater unit 20 according to the read pressing time.

As described above, in this embodiment, when the ambient temperature is low, the time for pressing the tape with the heater portion is extended. Therefore, it is possible to more stably bond the portions where the tapes overlap each other, and the above embodiments. In addition to the effects of the above embodiments, the tape can be thermally bonded more stably.
In each of the above embodiments, when the ambient temperature is read from the storage unit, the ambient temperature is displayed on the display unit 31 of the banknote handling machine 30, so that the staff handling the banknote handling machine is notified of the ambient temperature. You may make it do.

  Moreover, you may enable it to perform input operation which changes the temperature of the heater block 21 from the input part 32 of the banknote processing machine 30, for example, after notifying an attendant of atmospheric temperature, it is arbitrary according to atmospheric temperature by the input part 32 from an attendant. When there is an input for changing the temperature of the heater block 21, it is made to follow the contents inputted by the staff.
