The coin wrapping machine 1 includes an input port 2 and a touch sensor panel 4. The input port 2 is provided at an upper position of the coin wrapping machine 1. The input port 2 receives loose coins to be packaged by an operator. The input port 2 is provided with a cover 3 that opens and closes the input port 2. The cover 3 is configured to be manually openable and closable.
The touch sensor panel 4 accepts inputs for various settings such as denomination designation information in the packaging operation, and operation inputs for starting and stopping the packaging process. Further, the touch sensor panel 4 displays guidance and setting contents for various settings such as wrapping operations and printing contents as a result of counting coins in the coin wrapping machine 1. The touch sensor panel 4 is provided near the input port 2 .

FIG. 2 is a schematic diagram showing the internal structure of the coin packaging machine according to the first embodiment.
The coin wrapping machine 1 includes a stacking section 10, a medium supply section 30, and a wrapping section 50.
The stacking unit 10 stacks up loose coins that are inserted all at once through the open slot 2 . Hereinafter, the coins accumulated in the accumulation section 10 will be referred to as accumulated coins C. The medium supply section 30 supplies the packaging medium S to the packaging section 50. The packaging section 50 wraps the accumulated coins C accumulated in the accumulation section 10 with the packaging medium S supplied from the medium supply section 30.

《Configuration of accumulation section》
The stacking section 10 includes a rotating hopper 11, a coin passage 12, a pair of stacking drums 13, and a horizontal shutter 14.

The rotary hopper 11 receives loose coins thrown in at once through the slot 2. The rotating hopper 11 feeds out coins one by one by centrifugal force generated by rotation. The coin passage 12 is a passage that conveys coins fed out from the rotating hopper 11 between a pair of collecting drums 13.
The coin passage 12 is provided with a feed belt 121 that transports coins one by one. A discriminating unit (not shown) is provided in the middle of the coin passage 12, and the authenticity, denomination, etc. of the coins conveyed in the coin passage 12 are determined as necessary. Here, the coin passage 12 is provided with an exclusion hole (not shown), and coins that are not determined to be genuine coins by the discrimination section fall through the exclusion hole. That is, the coin passage 12 transports only genuine coins between the pair of accumulating drums 13.

A pair of accumulation drums 13 accumulate coins that have passed through the coin passage 12. Each stacking drum 13 has a spiral protrusion 131, and with the height positions of the protrusions 131 matched, the stacking drums 13 are arranged opposite to each other in synchronization with the supply of coins from the coin passage 12. It is intermittently rotated in the direction. As a result, the coins supplied through the coin passage 12 are placed on the protrusions 131 of the pair of collecting drums 13 and lowered one step, and the coins supplied thereafter are stacked on top of the previous coins. 13, a plurality of coins are stacked vertically to form a stacked coin C.

The horizontal shutter 14 is provided below the pair of stacking drums 13. The horizontal shutter 14 allows a predetermined number of coins C to be stacked on the pair of stacking drums 13 to be placed thereon. That is, the horizontal shutter 14 also serves as a bottom wall on which the accumulated coins C are placed. The horizontal shutter 14 is configured to be openable and closable. When the horizontal shutter 14 opens, the accumulated coins C placed on the upper surface of the horizontal shutter 14 are delivered to the packaging section 50 below.

《Configuration of packaging department》
The packaging section 50 includes a support rod 51, three packaging rollers 52, a packaging motor 53, and a crimping section 54.
The support rod 51 supports the accumulated coins C delivered from the horizontal shutter 14 from below. That is, above the support rod 51, there is provided a generally cylindrical accumulated coin arrangement space in which the accumulated coins C are arranged. The three wrapping rollers 52 are arranged along the vertical direction so as to respectively surround the stacked coin arrangement space. The three packaging rollers 52 are configured to be able to approach and separate from each other. The packaging motor 53 rotates the packaging roller 52 around its axis.
The crimping section 54 crimps the packaging medium S wound around the stacked coins at the upper and lower ends of the stacked coins C.

The support rod 51 is fixed to the tip of a support rod arm 511 that is provided to be movable up and down, and is moved directly below the horizontal shutter 14 when the horizontal shutter 14 is released by the operation of a support rod arm cam and a support rod arm relief cam (not shown). Allotted. Thereby, the support rod 51 receives the falling stack of coins C at its upper end, and is then lowered vertically to place the stack of coins C between the three wrapping rollers 52.

The wrapping unit 50 holds the stacked coins C between the wrapping rollers 52 by bringing the wrapping rollers 52 close to each other. When the packaging medium S is supplied between the accumulated coins C and the packaging roller 52 by the medium supply unit 30, the packaging unit 50 rotates the packaging roller 52 by operating the packaging motor 53, so that the packaging medium S is accumulated. It is wound around the cylindrical surface of coin C. Here, the packaging medium S has a width dimension larger than the height of the accumulated coins C. The packaging motor 53 is an example of a roller actuator that rotates the multiple packaging rollers 52 around a rotation axis.

FIG. 3 is a perspective view showing the configuration of the caulking part according to the first embodiment.
The crimping section 54 includes an upper crimping claw 541, a lower crimping claw 542, an upper arm 543, a lower arm 544, a guide rod 545, a spring 546, a cam mechanism 547, and a cam motor 548.

The upper crimping claw 541 is hooked onto the upper end of the packaging medium S wound around the accumulated coins C, and is biased downward to swage the upper end of the packaging medium S. The upper crimping claw 541 is fixed to the upper arm 543.
The lower crimping claw 542 is hung on the lower end of the packaging medium S wound around the accumulated coins C, and is biased upward to swage the lower end of the packaging medium S. The lower crimping pawl 542 is fixed to the lower arm 544.

The upper arm 543 and the lower arm 544 are supported by a guide rod 545 so as to be slidable in the vertical direction. Accordingly, the upper arm 543 and the lower arm 544 can be moved closer to each other or separated from each other. That is, as the upper arm 543 and the lower arm 544 approach or separate from each other, the upper crimping claw 541 and the lower crimping claw 542 approach or separate from each other.
Spring 546 is attached to connect upper arm 543 and lower arm 544. The spring 546 constantly urges the upper arm 543 and the lower arm 544 toward each other.

The cam mechanism 547 transmits power to the upper arm 543 and the lower arm 544 to bring them closer to each other or to move them apart. The cam mechanism 547 includes a first cam 61 , a first cam follower 62 , a first swing arm 63 , a second cam 64 , a second cam follower 65 , and a second swing arm 66 .
The first cam 61 and the second cam 64 are rotationally driven along a vertical plane by a cam motor 548. The first cam 61 and the second cam 64 each have the same shape, and are fixed to the rotating shaft so as to be point symmetrical about the rotating shaft.
The first cam follower 62 rolls along the cam surface of the first cam 61. The first cam follower 62 is attached to the first swing arm 63. The first end of the first swing arm 63 is supported by a fixed shaft (not shown) so as to be rotatable along a vertical plane. A roller (not shown) that rolls along the lower surface of the upper arm 543 is provided at the second end of the first swing arm 63 .
The second cam follower 65 rolls along the cam surface of the second cam 64. The second cam follower 65 is attached to the first end of the second swinging arm 66. The first end of the second swing arm 66 is supported by a fixed shaft (not shown) so as to be rotatable along a vertical plane. A roller (not shown) that rolls along the upper surface of the lower arm 544 is provided at the second end of the second swing arm 66 .

Therefore, when the cam motor 548 operates with the accumulated coins C arranged in the accumulated coin arrangement space, the first cam 61 and the second cam 64 are rotationally driven. Thereby, the first cam follower 62 and the second cam follower 65 are displaced along the cam surfaces of the first cam 61 and the second cam 64. Thereby, the first swing arm 63 and the second swing arm 66 are caused to swing in a vertical plane about their respective fixed axes. The first swing arm 63 presses the lower surface of the upper arm 543 due to the swing movement, and the second swing arm 66 presses the upper surface of the lower arm 544, thereby causing the upper arm 543 and the lower arm 544 to , move vertically toward or away from each other.
When the upper arm 543 and the lower arm 544 approach each other from the separated state, the upper crimping pawl 541 and the lower crimping pawl 542 crimp the packaging medium S wound around the accumulated coins C.
In other words, the cam motor 548 is an example of a crimping actuator that moves the upper crimping claw 541 and the lower crimping claw 542, which are a pair of crimping claws, toward each other. Note that in other embodiments, the caulking actuator may be realized by a hydraulic cylinder or a linear motor.

《Configuration of medium supply section》
FIG. 4 is a top view showing the configuration of the medium supply unit according to the first embodiment.
The medium supply section 30 includes a roll support section 31 , a paper feed roller 32 , an auxiliary roller 33 , and a pair of insertion guide plates 34 .

The roll support section 31 rotatably supports the packaging medium roll S1. The packaging medium roll S1 is formed into a roll shape by winding a long sheet-like packaging medium S made of paper or resin film. The roll support section 31 includes a horizontally arranged platform 311 and a support shaft 312 extending vertically upward from the center of the platform 311 . The packaging medium roll S1 is placed on the platform 311 with the support shaft 312 inserted toward the inner circumference. The packaging medium roll S1 rotates together with the platform 311. The roll support portion 31 has a rotation resistance portion (not shown) that applies rotation resistance to the base portion 311 . Therefore, the table part 311 rotates when an external force of a predetermined value or more is applied, and stops due to the resistance of the rotation resistance part when the external force is no longer applied. A capacitive sensor 313 is provided on the upper surface of the platform 311 and extends in the radial direction of the packaging medium roll S1. The capacitance sensor 313 measures the capacitance at the top of the platform 311 . The capacitance measured by the capacitance sensor 313 changes depending on the material and quantity of the packaging medium roll S1 installed on the stand 311.
Note that the capacitance sensor 313 may be directly attached to the base 311, or may be mounted on a circuit board placed on the bottom surface of the base 311. By mounting the capacitance sensor 313 on the circuit board, it is possible to prevent the capacitance sensor 313 from being scratched by the packaging medium S set on the stand 311 and to increase the durability of the capacitance sensor 313. can.

FIG. 5 is a diagram showing the relationship between the measured value of the capacitance sensor and the amount and material of the packaging medium roll according to the first embodiment.
As shown in FIG. 5, when the thickness of the packaging medium roll S1 is the same, the capacitance value detected by the capacitance sensor 313 is different depending on whether the material is resin or paper. Specifically, the value of the capacitance when the resin packaging medium roll S1 is placed on the stand 311 is the value of the electrostatic capacitance when the resin packaging medium roll S1 is placed on the stand 311. It can be seen that the value is smaller than the capacitance value.
Here, if the thickness of the new packaging media roll S1 is the same regardless of the material, check the value of capacitance when the new packaging media roll S1 is set in the media supply unit 30. It can be seen that the material of the packaging medium S can be specified. For example, when the thickness of the new packaging medium roll S1 is 45.0 mm, it can be seen that the material of the packaging medium S is paper if the capacitance value is greater than or equal to the first threshold value. If the capacitance value is less than the second threshold value, it can be seen that the material of the packaging medium S is resin.

Returning to FIG. 4, the paper feed roller 32 and the auxiliary roller 33 are provided near the packaging section 50 between the roll support section 31 and the packaging section 50. By rotating, the paper feed roller 32 winds up the packaging medium S from the packaging medium roll S1 supported by the roll support section 31 and supplies it to the packaging section 50. The auxiliary roller 33 is provided to face the paper feed roller 32 so that the packaging medium S is held between the paper feed roller 32 and the auxiliary roller 33 .
The insertion guide plate 34 is a wall plate provided on the path of the packaging medium S from the roll support section 31 to the paper feed roller 32 and the auxiliary roller 33.

Processing for controlling the coin wrapping machine 1 is stored in the storage 75 in the form of a program. The processor 71 reads the program from the storage 75, expands it into the main memory 73, and executes processing according to the program. Further, the processor 71 reserves a predetermined storage area in the main memory 73 according to the program. Examples of the processor 71 include a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and a microprocessor.

The program may be for realizing a part of the functions to be performed by the control device 70. For example, the program may function in combination with other programs already stored in storage or in combination with other programs installed in other devices.

Examples of the storage 75 include magnetic disks, optical disks, magneto-optical disks, semiconductor memories, and the like. Storage 75 may be an internal medium directly connected to the bus of control device 70, or may be an external medium connected to control device 70 via interface 77 or a communication line. Further, when this program is distributed to the control device 70 via a communication line, the control device 70 that receives the distribution may develop the program in the main memory 73 and execute the above processing. In at least one embodiment, storage 75 is a non-transitory tangible storage medium.

Note that in other embodiments, the control device 70 may include a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device) in addition to or in place of the above configuration. Examples of PLDs include PAL (Programmable Array Logic), GAL (Generic Array Logic), CPLD (Complex Programmable Logic Device), and FPGA (Field Programmable Gate Array). In this case, part or all of the functions realized by the processor 71 may be realized by the integrated circuit. Such an integrated circuit is also included in an example of a processor.

The processor 71 includes a measurement value acquisition section 711, an installation detection section 712, a material identification section 713, an operation mode determination section 714, a signal output section 715, a remaining amount identification section 716, and a display control section 717 by executing a program. . Furthermore, the processor 71 secures storage areas for the measured value storage section 731 and the material storage section 732 in the main memory 73 when executing the program. The measured value storage unit 731 stores the measured value of capacitance by the capacitance sensor 313. The material storage section 732 stores the material of the packaging medium roll S1 set in the medium supply section 30.
In addition, the storage 75 includes a first remaining amount function 751 indicating the relationship between the remaining amount of the packaging medium roll S1 and the capacitance when the material of the packaging medium S is resin, as shown in FIG. A second remaining amount function 752 indicating the relationship between the remaining amount of the packaging medium roll S1 and the capacitance when the material of S is paper is stored. Note that the term "function" is not limited to one that represents a relationship as a mathematical formula, but also includes one that represents a relationship as a table.

The measured value acquisition unit 711 acquires the measured value from the capacitance sensor 313. The measured value acquisition unit 711 records the acquired measured value in the measured value storage unit 731.

The installation detection unit 712 detects that a new packaging medium roll S1 is installed in the medium supply unit 30 based on the measurement value acquired by the measurement value acquisition unit 711. Specifically, the installation detection unit 712 detects a state in which the measured value of capacitance is less than a third threshold value corresponding to a state in which the remaining amount of the packaging medium roll S1 is zero, and a third threshold value indicating that the packaging medium roll S1 is present. 4 or more, it is determined that a new packaging medium roll S1 has been installed in the medium supply unit 30. When replacing the packaging media roll S1, the old packaging media roll S1 is removed from the media supply unit 30, but at this time, the measured value of the capacitance is always less than the third threshold value. Therefore, the installation detection unit 712 detects that a new packaging medium roll S1 has been installed in the medium supply unit 30 by detecting that the measured value of capacitance changes from less than the third threshold value to the fourth threshold value or more. can be detected.

The material identifying unit 713 identifies the material of the packaging medium roll S1 based on the measured value acquired by the measured value acquiring unit 711 when the installation detecting unit 712 detects the installation of the packaging medium roll S1. Specifically, the material identifying unit 713 identifies that the material of the packaging medium roll S1 is paper when the measured value acquired by the measured value acquiring unit 711 is equal to or greater than the first threshold shown in FIG. On the other hand, the material identifying unit 713 identifies that the material of the packaging medium roll S1 is resin when the measured value acquired by the measured value acquiring unit 711 is less than the second threshold shown in FIG. The material specifying unit 713 records the specified material in the material storage unit 732.

The operation mode determination unit 714 determines an operation mode that defines the rotational speed of the cam motor 548 based on the material stored in the material storage unit 732. The operation modes of the coin packaging machine 1 include a first mode for crimping the packaging medium S made of paper and a second mode for crimping the packaging medium S made of resin. The first mode is a mode in which the rotational speed of the cam motor 548 is driven at the first speed. The second mode is a mode in which the rotational speed of the cam motor 548 is driven at the second speed. For example, the first speed may be set to twice the second speed.

The signal output unit 715 outputs to the packaging motor 53 a packaging instruction signal that causes the packaging motor 53 to rotate at a constant speed. Further, the signal output unit 715 outputs to the cam motor 548 a caulking instruction signal that causes the cam motor 548 to rotate at a speed related to the operation mode determined by the operation mode determination unit 714.

The remaining amount identifying unit 716 identifies the remaining amount of the packaging medium roll S1 based on the material stored in the material storage unit 732 and the measured value acquired by the measured value acquiring unit 711. Specifically, the remaining amount identifying unit 716 determines a function for calculating the remaining amount based on the material stored in the material storage unit 732. That is, when the material stored in the material storage section 732 is paper, the remaining amount specifying section 716 reads the first remaining amount function 751 from the storage 75 . On the other hand, when the material stored in the material storage section 732 is resin, the remaining amount specifying section 716 reads the second remaining amount function 752 from the storage 75 . The remaining amount specifying unit 716 specifies the remaining amount of the packaging medium roll S1 by substituting the measured value obtained by the measured value obtaining unit 711 into the read function.
The display control section 717 outputs a display signal for displaying the remaining amount of the packaging medium roll S1 specified by the remaining amount specifying section 716 to the touch sensor panel 4.

《Coin wrapping machine control method》
The coin wrapping machine executes the following monitoring process for the packaging medium roll S1 at regular control intervals. In the packaging medium roll S1 monitoring process, whether or not the packaging medium roll S1 has been replaced, the material of the packaging medium S, and the remaining amount of the packaging medium S are specified.
FIG. 7 is a flowchart showing a packaging medium roll monitoring process performed by the coin packaging machine according to the first embodiment.
First, the measured value acquisition unit 711 acquires a measured value from the capacitance sensor 313 (step S1). The installation detection unit 712 determines whether the measured value of capacitance stored in the measured value storage unit 731 is less than a third threshold (step S2). That is, the installation detection unit 712 determines whether the remaining amount of the packaging medium roll S1 was zero at the time of the previous measurement. If the measured value of capacitance stored in the measured value storage unit 731 is less than the third threshold (step S2: YES), the installation detection unit 712 determines that the measured value acquired in step S1 is greater than or equal to the fourth threshold. It is determined whether or not (step S3). That is, the installation detection unit 712 determines whether the packaging medium roll S1 is present on the platform 311 during the current measurement. If the measured value acquired in step S1 is equal to or greater than the fourth threshold (step S3: YES), the installation detection unit 712 determines that the packaging medium roll S1 has been replaced. On the other hand, if the measured value of capacitance stored in the measured value storage unit 731 is greater than or equal to the third threshold (step S2: NO), or if the measured value acquired in step S1 is less than the fourth threshold ( Step S3: NO), the installation detection unit 712 determines that the packaging medium roll S1 has not been replaced.

When the installation detection unit 712 determines that the packaging medium roll S1 has been replaced, the material identification unit 713 determines whether the measured value acquired in step S1 is greater than or equal to the first threshold (step S4). If the measured value is greater than or equal to the first threshold, the material specifying unit 713 specifies that the material of the packaging medium S is paper, and records the specified material in the material storage unit 732 (step S5).

On the other hand, if the measured value is less than the first threshold (step S4: NO), the material identification unit 713 determines whether the measured value acquired in step S1 is less than the second threshold (step S6). If the measured value is less than the second threshold, the material specifying unit 713 specifies that the material of the packaging medium S is resin, and records the specified material in the material storage unit 732 (step S7).

On the other hand, if the measured value is greater than or equal to the second threshold and less than the first threshold (step S6: NO), the display control unit 717 outputs a display signal to the touch sensor panel 4 to display a screen indicating the error. (Step S8), the process ends. Note that if the material identification unit 713 determines that the material of the packaging medium S is neither paper nor resin after the replacement of the packaging medium roll S1 is confirmed, the material identification unit 713 uses the measured value and other static materials stored in the material storage unit 732. It may be possible to compare the capacitances and notify that the packaging medium S is made of the specified material based on the capacitances that match within a predetermined error range. Further, the material identifying unit 713 may identify the material by comparing it with the capacitance stored in an external server.

If it is determined in step S2 or step S3 that the packaging medium roll S1 has not been replaced, the remaining amount identifying unit 716 determines whether the material stored in the material storage unit 732 is paper or resin. (Step S9).

When the material stored in the material storage section 732 is paper (step S9: paper), or when the material is identified as paper in step S5, the remaining amount specifying section 716 stores the number stored in the storage 75. The remaining amount of the packaging medium roll S1 is specified by substituting the measured value obtained in step S1 into the remaining amount function 751 (step S10).
On the other hand, when the material stored in the material storage section 732 is resin (step S9: resin), or when the material is identified as resin in step S7, the remaining amount identification section 716 determines whether the material stored in the storage 75 is The remaining amount of the packaging medium roll S1 is specified by substituting the measured value acquired in step S1 into the second remaining amount function 752 (step S11).

The display control unit 717 outputs a display signal for displaying the remaining amount of the packaging medium roll S1 specified in step S10 or step S11 to the touch sensor panel 4 (step S12). Examples of the display of the remaining amount of the packaging medium roll S1 include a display of the thickness of the packaging medium roll S1, a display of the remaining number of times of use, a near empty display, an empty display, and the like.
Then, the measured value acquisition unit 711 records the measured value acquired in step S1 in the measured value storage unit 731 (step S13), and ends the process.

FIG. 8 is a flowchart showing the packaging process of accumulated coins by the coin packaging machine according to the first embodiment. FIG. 9 is a time chart showing the operation of the coin packaging machine according to the first embodiment during packaging processing of accumulated coins. FIG. 9 shows a time chart showing changes over time in the speeds of the paper feed motor, packaging motor 53, and cam motor 548, which are not shown, respectively.
When a certain amount of loose coins are put into the coin packaging machine 1 and the stacked coins C are placed in the stacked coin placement space by opening the horizontal shutter 14, the operation mode determining unit 714 determines the material stored in the material storage unit 732. , it is determined whether the material is paper or resin (step S31).

When the material stored in the material storage unit 732 is paper (step S31: paper), the operation mode determining unit 714 determines the operation mode to be the first mode (step S32). On the other hand, when the material stored in the material storage section 732 is resin (step S31: resin), the operation mode determining section 714 determines the operation mode to be the second mode (step S33).

The signal output unit 715 outputs a rotation instruction signal to the cam motor 548 to rotate the cam motor at a speed corresponding to the determined operation mode (step S34). As a result, as shown in the time chart of the cam motor 548 in FIG. 9, the speed of the cam motor 548 in the second mode shown by the solid line and the speed of the cam motor 548 in the first mode shown by the broken line are different from each other.
Thereafter, the signal output unit 715 outputs a rotation instruction signal to a paper feed motor (not shown) that rotates the paper feed roller 32 at a constant speed (step S35). After rotating the paper feed motor for a certain period of time, the signal output unit 715 outputs a stop instruction signal to the paper feed motor (step S36). Next, the signal output unit 715 outputs a rotation instruction signal to cause the packaging motor 53 to rotate at a constant speed (step S37). After that, the signal output unit 715 outputs a stop instruction signal to the cam motor 548 and the packaging motor 53 (step S38). For example, in the embodiment, when the first cam 61 and the second cam 64 each rotate once when the cam motor 548 rotates once, the signal output unit 715 64) makes one revolution, outputs a stop instruction signal to the cam motor 548. As a result, as shown in the time chart of the cam motor 548 in FIG. 9, the stop timing of the cam motor 548 in the second mode shown by the solid line and the stop timing of the cam motor 548 in the first mode shown by the broken line are different from each other.
Further, the signal output unit 715 outputs a stop instruction signal to the packaging motor 53 when the packaging motor 53 rotates to a predetermined stop position. That is, in the example shown in FIG. 9, the packaging motor 53 and the cam motor 548 are stopped at different timings, but the packaging motor 53 and the cam motor 548 may be stopped at substantially the same timing.

《Action/Effect》
As described above, according to the first embodiment, the control device 70 determines the operation mode that defines the rotational speed of the cam motor 548, and outputs a control signal to the cam motor 548 based on the determined operation mode. Thereby, the coin wrapping machine 1 can change the approach speed of the upper crimping claw 541 and the lower crimping claw 542 per rotation of the packaging roller 52 to a preset operation mode according to the material of the packaging medium. It can be changed with . Therefore, by appropriately determining the operation mode according to the packaging medium, the coin wrapping machine 1 can crimp both ends of the packaging medium S in which the accumulated coins C are wrapped at an appropriate speed.

Further, according to the first embodiment, the control device 70 specifies the material of the packaging medium S based on the measured value of the capacitance sensor 313, and determines the operation mode based on the specified material. Thereby, the coin packaging machine 1 can automatically determine the material of the packaging medium S set on the stand 311 based on the measured value of the capacitance sensor 313, and can determine the material of the packaging medium S according to the material of the packaging medium S. In the determined operation mode, both ends of the packaging medium for packaging the accumulated coins C can be crimped at an appropriate speed.
Note that, although the capacitance sensor 313 according to the first embodiment is provided along the radial direction of the packaging medium roll S1 on the platform 311, other embodiments are not limited to this. For example, in other embodiments, a capacitive sensor 313 may be provided along the support shaft 312. Even if the capacitance sensor 313 is provided along the support shaft 312, the output value of the capacitance sensor 313 changes depending on the material and remaining amount of the packaging medium roll S1. The amount can be appropriately specified.

<Second embodiment>
The coin packaging machine 1 according to the first embodiment keeps the rotation speed of the packaging motor 53 constant and changes the rotation speed of the cam motor 548 according to the material of the packaging medium S. On the other hand, in the coin packaging machine 1 according to the second embodiment, the rotation speed of the cam motor 548 is kept constant, and the rotation speed of the packaging motor 53 is changed according to the material of the packaging medium S.

FIG. 10 is a flowchart showing the packaging process of accumulated coins by the coin packaging machine according to the second embodiment. FIG. 11 is a time chart showing the operation of the coin packaging machine according to the second embodiment during packaging processing of accumulated coins. FIG. 11 shows time charts showing changes over time in the speeds of the paper feed motor, wrapping motor 53, and cam motor 548, which are not shown.
When a certain amount of loose coins are put into the coin packaging machine 1 and the stacked coins C are placed in the stacked coin placement space by opening the horizontal shutter 14, the operation mode determining unit 714 determines the material stored in the material storage unit 732. , it is determined whether the material is paper or resin (step S131). When the material stored in the material storage section 732 is paper (step S131: paper), the operation mode determining section 714 determines the operation mode to be the first mode (step S132). On the other hand, if the material stored in the material storage section 732 is resin (step S131: resin), the operation mode determination section 714 determines the operation mode to be the second mode (step S133). .

Next, the signal output unit 715 outputs a rotation instruction signal to cause the cam motor to rotate at a constant speed (step S134).

In the second embodiment, the rotation speed of the cam motor is set to the rotation speed of the cam motor when the packaging medium described in the first embodiment is resin (second mode). In this case, the rotational speed of the packaging motor in the first mode is set to about twice that in the second mode. Note that the rotation speed of the cam motor may be set to the rotation speed of the cam motor when the packaging medium is paper (first mode) as described in the first embodiment, and in this case, the rotation speed of the packaging motor is The speed in the first mode is approximately 1/2 that of the second mode.

Next, the signal output unit 715 outputs a rotation instruction signal to a paper feed motor (not shown) that rotates the paper feed roller 32 at a constant speed (step S135). After rotating the paper feed motor for a certain period of time, the signal output unit 715 outputs a stop instruction signal to the paper feed motor (step S136). Next, the signal output unit 715 outputs a rotation instruction signal to the packaging motor 53 to rotate the packaging motor 53 at a speed according to the operation mode determined in step S132 or step S133 (step S137). For example, the rotation speed of the packaging motor 53 when the operation mode is the first mode may be set to 1/2 of the rotation speed of the packaging motor 53 when the operation mode is the second mode. As a result, as shown in the time chart of the packaging motor 53 in FIG. 11, the speed of the packaging motor 53 in the second mode shown by the broken line and the speed of the packaging motor 53 in the first mode shown by the solid line are different from each other.

After that, the signal output unit 715 outputs a stop instruction signal to the packaging motor 53 and the cam motor 548 (step S138).

《Action/Effect》
Thus, according to the second embodiment, the control device 70 determines the operation mode that defines the rotational speed of the packaging motor 53 and outputs a control signal to the packaging motor 53 based on the determined operation mode. Thereby, the coin wrapping machine 1 can change the number of rotations of the wrapping roller 52 per the moving speed of the upper crimping claw 541 and the lower crimping claw 542 according to the operation mode. Thereby, by determining an appropriate operation mode according to the material of the packaging medium, it is possible to appropriately package the accumulated coins C.

Note that the control device according to the first embodiment keeps the packaging motor 53 at a constant speed and changes the rotational speed of the cam motor 548 according to the operation mode, and the control device according to the second embodiment keeps the cam motor 548 at a constant speed. As the speed, the rotational speed of the packaging motor 53 is changed according to the operation mode. On the other hand, in other embodiments, controller 70 may change the rotational speed of both packaging motor 53 and cam motor 548 depending on the operating mode. In either embodiment, the operating mode defines the relative relationship between the rotational speed of the packaging motor 53 and the rotational speed of the cam motor 548.

<Third embodiment>
The control device 70 according to the first embodiment and the second embodiment specifies the material of the packaging medium S based on the measured value of the capacitance sensor 313. On the other hand, the control device 70 according to the third embodiment specifies the material of the packaging medium S using an optical sensor.

FIG. 12 is a top view showing the configuration of the medium supply unit according to the third embodiment. As shown in FIG. 12, in place of the capacitance sensor 313, a first light emitting element 341, a first light receiving element 342, a second light emitting element 343, and a second light receiving element 344 are provided.
The first light emitting element 341 and the second light emitting element 343 are provided on one of the pair of insertion guide plates 34. The first light receiving element 342 and the second light receiving element 344 are provided on the other of the pair of insertion guide plates 34. The first light receiving element 342 is provided to face the first light emitting element 341. The second light receiving element 344 is provided to face the second light emitting element 343.

The first light emitting element 341 emits light of a wavelength that passes through the resin and is absorbed or reflected by the paper. This shows that if the first light receiving element 342 cannot receive the light emitted by the first light emitting element 341, the paper packaging medium S is passing between the pair of insertion guide plates 34. That is, the first light emitting element 341 and the first light receiving element 342 function as a paper detection sensor.
The second light emitting element 343 emits light of a wavelength that is absorbed or reflected by resin and paper. This shows that if the second light receiving element 344 cannot receive the light emitted by the second light emitting element 343, the packaging medium S made of paper or resin is passing between the pair of insertion guide plates 34. That is, the second light emitting element 343 and the second light receiving element 344 function as a medium detection sensor.

The measured value acquisition unit 711 according to the third embodiment acquires the measured values of the light amounts of the first light receiving element 342 and the second light receiving element 344. Then, the material specifying unit 713 determines that the packaging medium roll S1 is not set when the amount of light received by the first light receiving element 342 and the amount of light received by the second light receiving element are both equal to or greater than the threshold value. The material identifying unit 713 determines that the material of the packaging medium S is resin when the amount of light received by the first light receiving element 342 is greater than or equal to the threshold and the amount of light received by the second light receiving element 344 is less than the threshold. The material identifying unit 713 determines that the material of the packaging medium S is paper when the amount of light received by the first light receiving element 342 and the amount of light received by the second light receiving element 344 are less than the threshold values.

In this way, the control device 70 according to the third embodiment can identify the material of the packaging medium S even using the measured values of sensors other than the capacitance sensor 313. Note that in the third embodiment, the material of the packaging medium S is specified using two types of light emitting elements, but the material of the packaging medium S is not limited to this in other embodiments. For example, in another embodiment, the light emitting element emits light of a wavelength whose absorption rate differs between resin and paper, and the control device 70 identifies the material of the packaging medium S based on the light reception level at the light receiving element. You can.
