Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coin wrapping apparatus for wrapping stacked coins, and relates to a coin wrapping apparatus capable of realizing a faster coin wrapping process.
[0002]
[Prior art]
An outline of the configuration of the coin wrapping apparatus will be described with reference to FIG. A coin wrapping apparatus 50 shown in FIG. 5 includes three wrapping rollers 51 for wrapping coins arranged around stacked coins (not shown). The stacked coins are held by an appropriate stacked coin holding unit (not shown).
[0003]
The coin wrapping apparatus 50 includes a pair of paper feed rollers 52 that supply the wrapping paper P. The paper feed roller 52 is configured to send out the wrapping paper P wound in a roll shape in a predetermined direction. The guide rail 53 guides the wrapping paper P supplied from the paper feed roller 52 between the stacked coins and the wrapping roller 51.
[0004]
Japanese Patent Publication No. 5-12205 discloses a control mode as shown in FIG. 6 regarding the relationship between the feeding speed of the wrapping paper P by the paper feeding roller 52 and the wrapping speed of the wrapping paper by the packaging roller 51.
[0005]
As shown in FIG. 6, the control form disclosed in the publication is such that, in the first half step (TA), the feeding speed by the feeding roller 52 and the wrapping speed of the wrapping paper by the packaging roller 51 are both low. It is linked to match. Then, after the wrapping paper P having a predetermined length is fed out by the paper feed roller, the paper feed roller 51 is stopped and the wrapping paper P is cut to drive the packaging roller 52 at a speed higher than the winding speed. (TB).
[0006]
In such a control mode, when the wrapping paper P is sandwiched between the wrapping roller 51 and the accumulated coins, the moving speed (paper feeding speed) of the wrapping paper P and the peripheral speed of the wrapping roller 51 are the same. Therefore, the impact during the clamping is small.
[0007]
[Problems to be solved by the invention]
However, in the control mode shown in Japanese Patent Publication No. 5-12205, since the paper is fed at a low speed until the delivery of the wrapping paper P having a predetermined length is completed, the coin wrapping process cannot be sufficiently speeded up.
[0008]
Further, since the paper feed roller 52 and the packaging roller 51 move the wrapping paper at a constant speed, when the paper feeding roller 52 slips due to the load of the wrapping paper P, the packaging roller 51 pulls and cuts the wrapping paper P. The wrapping paper P may be damaged or partially torn.
[0009]
The present invention has been made in consideration of such points, and an object of the present invention is to provide a coin wrapping apparatus that can realize a faster coin wrapping process without damaging the wrapping paper.
[0010]

[0016]
In this case, a preliminary feeding step for winding the next wrapping paper can be realized.
[0017]

[0024]
DETAILED DESCRIPTION OF THE INVENTION
Below, 1st Embodiment of the coin packaging apparatus by this invention is described based on FIG.1 and FIG.3.
[0025]
FIG. 1 is a schematic perspective view showing a configuration example of a coin wrapping apparatus according to a first embodiment of the present invention. As shown in FIG. 1, the coin wrapping apparatus 10 according to the present embodiment includes three wrapping rollers 11 for wrapping coins arranged around a stacked coin 40 (not shown in FIG. 1; see FIG. 2). It has. The stacked coin 40 is held by an appropriate stacked coin holding unit 15.
[0026]
Moreover, the coin wrapping apparatus 10 includes a pair of paper feed rollers 12 (paper feed means) for supplying the wrapping paper P. The paper feed roller 12 is configured to feed the wrapping paper P wound in a roll shape in a predetermined direction. The guide rail 13 guides the wrapping paper P supplied from the paper feed roller 12 between the stacked coins 40 and the wrapping roller 11.
[0027]
As shown in FIGS. 1 and 2, the guide rail 13 is arranged so that the wrapping paper P delivered from the paper feed roller 12 is folded back to reach the wrapping roller 11 (see the solid line in FIG. 2). The guide rail 13 is provided only outside the guide track of the wrapping paper P, and a cutting blade 17 (cutting means) capable of cutting the wrapping paper P is provided inside the guide track. Thereby, when the wrapping paper P is separated from the guide track and is pulled between the paper feed roller 12 and the wrapping roller 11 (in the state of the one-dot chain line in FIG. 2), the wrapping paper P is cut by the cutting blade 17. It has become.
[0028]
The three wrapping rollers 11 are connected to a wrapping roller motor portion 21 that rotates each wrapping roller 11 and winds the wrapping paper P around the stacked coins 40. In this case, the packaging roller motor unit 21 is configured by connecting a low-speed motor 21a and a high-speed motor 21b in parallel. Further, a one-way clutch 21 c is disposed between the low speed motor 22 a and the packaging roller 11.
[0029]
The paper feed roller 12 is connected to a paper feed roller motor unit 22 that rotates the pair of paper feed rollers 12 to feed out the wrapping paper P.
[0030]
An encoder device 32 that detects the amount of rotation of the paper feed roller 12 is provided on the rotation shaft of the paper feed roller 12. Thereby, it is possible to detect the length of the wrapping paper sent out from the paper supply roller 12.
[0031]
The packaging roller motor unit 21, the paper feed roller motor unit 22, and the encoder device 32 are connected to a control unit 30 that appropriately controls them.
[0032]
In the present embodiment, the rotation diameters of the three packaging rollers 11 and the pair of paper feed rollers 12 are all equal. That is, the rotational speed of each roller corresponds to the winding speed of the wrapping paper P and the paper feeding speed, respectively.
[0033]
In FIG. 3, the control form by the control part 30 of this Embodiment is shown. As shown in FIG. 3, the control unit 30 controls the wrapping roller 11 by the wrapping roller motor unit 21 for a predetermined first wrapping time T <b> 1 from the start of the wrapping operation of the wrapping paper P (winding operation start timing). The rotational speed Rv1 is set to a low speed. Specifically, the packaging roller 11 is connected to the low-speed motor 21 a of the packaging roller motor unit 21.
[0034]
Here, the first winding time T1 is the time until the wrapping paper P is completely sandwiched between the wrapping roller 11 and the accumulated coins 40 at the rotational speed Rv1, for example, the wrapping paper P is stacked. This is the time required to make a full circle around the coin 40. During this time, it is preferable to guide the wrapping paper P at a low speed.
[0035]
Further, the control unit 30 is configured to increase the rotation speed Rv2 of the packaging roller 11 by the packaging roller motor unit 21 for a predetermined second winding time T2 following the first winding time T1. That is, Rv1 <Rv2. Specifically, the packaging roller 11 is connected to the high-speed motor 21b of the packaging roller motor 21 part. At this time, the rotation of the one-way clutch 21c is not transmitted to the low-speed motor 21a.
[0036]
On the other hand, the control unit 30 relates to the rotation speed of the paper feed roller 12 by the paper feed roller motor unit 22 (the paper feed speed of the wrapping paper P) for a predetermined first paper feed time t1 from the start of the winding operation of the wrapping paper P. ) Fv1 is set to a medium speed. That is, Rv1 <Fv1 <Rv2.
[0037]
As a result, in the overlap time of the first winding time T1 and the first paper feed time t1, the packaging supplied excessively between the paper feed roller 11 and the packaging roller 12 due to the relationship Rv1 <Fv1. The paper P is in a slack state (broken line state in FIG. 2).
[0038]
Here, in the present embodiment, as shown in FIG. 3, the first winding time T1 and the first paper feed time t1 have substantially the same length. However, the two do not necessarily need to match.
[0039]
Further, in the present embodiment, the control unit 30 relates to the rotation speed (wrapping paper) of the paper feed roller 12 by the paper feed roller motor unit 22 for a predetermined second paper feed time t2 following the first paper feed time t1. (P feeding speed) Fv2 is set to zero, that is, feeding is stopped. At this time, naturally, Fv2 <Rv2.
[0040]
As a result, the wrapping paper P (broken line in FIG. 2) that has been loosened during the overlapping time of the first winding time T1 and the first paper feeding time t1 is changed to the second winding time T2 and the second paper feeding time t2. Are overlapped because of the relationship of Fv2 <Rv2 (the one-dot chain line state in FIG. 2). At this time, as described above, the wrapping paper P and the cutting blade 17 come into contact with each other, and the wrapping paper P is cut.
[0041]
In the present embodiment, in particular, since the paper feed speed Fv2 of the wrapping paper P at the second paper feed time t2 is zero, the supply amount of the wrapping paper P detected by the encoder device 32 and the state where the wrapping paper P is cut. From the distance between the paper feed roller 12 and the cutting blade 17 in the one-dot chain line state (FIG. 2), it is easy to accurately set the length of the wrapping paper P to be cut to a predetermined length.
[0042]
Next, the effect | action of the coin packaging apparatus 10 of such this Embodiment is demonstrated.
[0043]
At the first winding time T1, the wrapping roller 11 is rotationally driven at the rotational speed Rv1 (low speed), and the wrapping paper P is securely sandwiched between the wrapping roller 11 and the accumulated coins 40. On the other hand, at the first supply time t1, the paper feed roller 12 is rotationally driven at the rotational speed Fv1 (> Rv1), that is, the wrapping paper P is supplied exceeding the winding speed of the wrapping roller 11, and the inside of the guide rail 13 (The broken line state in FIG. 2).
[0044]
The first paper feeding time t1 at this time requires time until the supply amount (paper feed amount) of the wrapping paper reaches a predetermined length according to the coin diameter. Since the paper feed roller 12 is rotated at a medium speed faster than Rv1, the predetermined amount is reached earlier.
[0045]
After the first winding time T1, the wrapping roller 11 is driven to rotate at the rotational speed Rv2 during the second wrapping time T2, and the wrapping paper P is wound between the wrapping roller 11 and the accumulated coins 40 at a high speed. . On the other hand, at the second supply time t2, the paper feed roller 12 is stopped, and the loose wrapping paper is stretched and brought into contact with the cutting blade 17 and cut due to the relationship Fv2 = 0 <Rv2.
[0046]
In the present embodiment, first winding time T1 + second winding time T2 <first supply time t1 + second supply time t2 = one cycle of winding work.
[0047]
As described above, according to the present embodiment, the wrapping paper P is sandwiched between the wrapping roller 11 and the accumulated coins 40 because the rotation speed Rv1 of the wrapping roller 11 at the first winding time T1 is low. When the wrapping paper is wrapped around the accumulated coins, it is possible to prevent an impact from being reduced and to wrap obliquely or to cause clogging, and the feeding speed Fv1 by the paper feeding roller 12 is set to the winding speed of the packaging roller 11. Since the medium speed is higher than the speed Rv1, the delivery of the wrapping paper of a predetermined length (the required length according to the coin diameter) is completed earlier regardless of the wrapping speed Rv1 of the wrapping roller. Time t1 can be shortened. As a result, the cycle for creating one wrapping coin is shortened, and a faster coin wrapping process can be realized.
[0048]
Further, the rotation speed (feeding speed of the wrapping paper P) Fv1 of the paper feeding roller 12 in the first paper feeding time T1 is the rotational speed of the wrapping roller 11 (winding speed of the wrapping paper P) in the first winding time T1. By being larger than Rv1, it can be effectively avoided that the wrapping paper P contacts the cutting blade 17 at an undesired timing. Thereby, damage to the wrapping paper P can be effectively avoided.
[0049]
Next, a second embodiment of the present invention will be described with reference to FIG. In the control mode illustrated in FIG. 4, the control unit 30 sets the sheet feeding speed Fv3 of the wrapping paper P by the sheet feeding roller 12 to Fv3> 0 for a predetermined third sheet feeding time t3 following the second sheet feeding time t2. It is like that.
[0050]
In this case, the first winding time T1 + the second winding time T2 <the first supply time t1 + the second supply time t2 + the third paper feed time t3 <one cycle of the winding process.
[0051]
Other configurations are substantially the same as those of the first embodiment described with reference to FIGS. In the present embodiment, members similar to those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
[0052]
According to the present embodiment, it is possible to realize the preliminary feeding process for the wrapping operation of the wrapping paper P in the next cycle by using the third paper feeding time t3. Thereby, a faster coin wrapping process can be realized.
[0053]
In FIG. 4, Fv3 = Fv1, but the value of Fv3 can be changed as appropriate.
[0054]
In addition, the control content which the control part 30 implement | achieved in each above embodiment may be implement | achieved by another aspect. That is, the method of sequentially performing each process performed by the control unit 30 is also a protection target required by the present application.
[0055]
【The invention's effect】
According to the present invention, the wrapping paper is sandwiched between the wrapping roller and the accumulated coins, and the wrapping paper is wound around the accumulated coins, with the winding speed Rv1 of the wrapping roller in the first winding time being relatively low. At the same time, it is possible to prevent the impact from being reduced to prevent the winding from occurring obliquely or causing clogging, and the feeding speed Fv1 by the feeding means is higher than the winding speed Rv1 of the packaging roller. Regardless of the winding speed Rv1, the delivery of the wrapping paper of a predetermined length (required length corresponding to the coin diameter) can be completed earlier, and the first paper feeding time can be shortened. As a result, the cycle for creating one wrapping coin is shortened, and a faster coin wrapping process can be realized.
[0056]
Further, since the wrapping paper feeding speed Fv1 by the paper feeding means in the first paper feeding time is Rv1 <Fv1, breakage of the wrapping paper can be effectively avoided.
[0057]
As described above, a faster coin wrapping process can be realized without damaging the wrapping paper.
