Abstract

PROBLEM TO BE SOLVED: To detect reliably the end of wrapping paper irrespective of whether the terminal end of rolled wrapping paper is connectively attached to a core tube, by disposing a detector for detecting the presence of the wrapping paper at a position located in the vicinity of a wrapping paper path, where the detector does not interfere with the wrapping paper feed path extending in the normal direction of the rolled wrapping paper. SOLUTION: An oblong hole 16 is opened into a wrapping paper table 12, and a detecting member 18 supported in a vertically movable manner on a supporting member perpendicularly provided on the underface of the wrapping paper table 12 is so provided as to face the position of the oblong hole 16. When rolled wrapping paper S is used up and in the case where the terminal end of the rolled wrapping paper S is connectively attached to a cylindrical core tube P, the distance between the terminal end of the wrapping paper S and a guide 13 provided in a direction in which the wrapping paper S is sent out becomes the shortest as shown by a wrapping paper feed path X in the Figure, and a wrapping paper feed path Y deviates from above the detecting member 18. As a result, the detecting member 18 is projected on the wrapping paper table 12, and an end state of the wrapping paper S is informed by a sensor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a coin wrapping machine in which a wrapping paper is wound around the outer periphery of a laminated coin to form a wrapping coin.

[0002]

2. Description of the Related Art Conventionally, in a packaging machine for forming packaging coins, stable supply of wrapping paper has been desired, and in order to quickly detect the situation where supply of wrapping paper becomes impossible and supply the wrapping paper, Various creative ideas have been made to detect the end of the wrapping paper.

For example, in a coin wrapping machine, a device for detecting near end of wrapping paper for wrapping accumulated coins is as follows.
The invention of Japanese Patent Laid-Open No. 54-121897 (known example) is disclosed.

In the above-mentioned known example, a loading stand (wrapping paper stand) for loading roll-shaped wrapping paper, and a tip of the roll-shaped wrapping paper loaded on the wrapping paper stand to a position for wrapping the accumulated coins. A detection device, which has a feed roller for feeding, further detects the presence or absence of the trailing end of the wrapping paper, while the wrapping paper is being fed out, and is provided at a position having a length for one wrapping of the accumulated coins. By doing so, the wrapping paper can be used without waste while determining the near end of the wrapping paper.

DISCLOSURE OF THE INVENTION The invention of the above-mentioned known example relates to the prior application of the present applicant, and in order to improve the working efficiency of the coin wrapping machine and reduce the operation of the operator, Although it was highly useful, there were some points that improvement was still desirable.

For example, if the end portion of the wrapping paper and the tubular member serving as the core of the roll-like wrapping paper are adhered by a tape or the like, the end portion of the wrapping paper is adhered even if the remaining amount of the wrapping paper runs out. Since the feed roller cannot send out the wrapping paper any more, and the detection means for detecting the presence or absence of the wrapping paper always detects the wrapping paper, the wrapping process is not stopped and the wrapping process is not stopped. There was a risk that defects would occur.

A first problem to be solved by the present invention is that the end of the roll-shaped wrapping paper is surely attached to the end of the wrapping paper even if the end of the wrapping paper is connected to the cylindrical core. An object of the present invention is to provide a detection device capable of detecting.

A second problem to be solved by the present invention is to provide a detection device having a simple structure and less fear of failure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, each embodiment of the present invention will be described with reference to the drawings.

(Embodiment 1) Structure In the wrapping paper end detection device 1 shown in FIG. 1, the wrapping paper supply mechanism 10 is mounted on a wrapping paper base 12 by a feed roller 11 driven by a rotation driving means (not shown). The outer end of the placed roll-shaped wrapping paper (S) is guided by the guide 13 and fed onto the outer periphery of the accumulated coins (C) arranged between the wrapping rollers 14 to form a wrapping coin. .

Further, the roll-shaped wrapping paper (S) is in a form of being wound in multiple layers on the cylindrical core (P), and the cylindrical core (P) is wrapped around the wrapping paper stand. The wrapping paper supply mechanism 10 is loaded by loosely fitting a bearing 15 protruding from the upper surface of the wrapping 12.

Further, as shown in FIG. 2, the long hole 16 is formed in the wrapping paper table 12, and the arrangement position thereof will be described later.

Further, a detecting member 18 oscillatably supported by a supporting member 17 vertically provided on the lower surface of the packaging paper table 12.
The U-shaped protruding portion 181 provided on one side is made to face the position of the elongated hole 16 and is attached to the other side of the detection member 18, and in the natural state, the detection member 18 appropriately shifts its center of gravity position. 2 is automatically urged in the clockwise direction in FIG. 2, its U-shaped protrusion 181 penetrates into the elongated hole 16 and is partially higher than the top surface of the wrapping paper table 12, The locking end 182 is configured to stabilize its posture in a state of being locked to the lower surface of the packaging paper table 12.

Further, a sensor 20 composed of a light emitting / receiving element for detecting the position of the detection piece 19 is provided on the support member 17 so as to face the detection piece 19, and a protrusion 181 of the detection member 18 is provided. Is not at the same height as the wrapping paper tray 12, the detection piece 19 formed at one end of the detection member 18 is not detected, and when the projecting portion 181 of the detection member 18 is projected above the wrapping paper tray 12, It is configured to detect this.

By the way, as shown in FIG. 1, the position of the long hole 16 provided in the wrapping paper stand 12 is a wrapping paper passage which connects the tangent position of the guide 13 and the axial center of the bearing 15 with a straight line. It is provided at a position that does not interfere with (X), and as a result, the U-shaped protrusion 181 of the detection member 18 that appears and disappears in the elongated hole 16 does not interfere with the wrapping paper passage (X). Will be deployed to.

Detecting the end of the wrapping paper With the above configuration, the protruding portion 181 of the detection member 18 is wrapped around the wrapping paper when the remaining amount of the roll-shaped wrapping paper (S) set on the wrapping paper base 12 is large. The paper (S) itself is pushed down to be immersed in the long hole 16 as shown by the broken line in FIG. 2, and the detection piece 19 provided on the detection member 18 is displaced counterclockwise to move away from the sensor 20. Then, it is recognized that the remaining amount of the rolled wrapping paper (S) is sufficient, and the coin wrapping processing work can be continued without any trouble.

Even when the remaining amount of the rolled wrapping paper (S) is reduced and the outer diameter thereof is reduced, the wrapping paper passage (Y) passes over the detecting member 18 in FIG. The position of the detection member 18 does not change, and the coin packaging processing operation can be continued.

By the way, when the roll-shaped wrapping paper (S) is used up, in the case of the roll-shaped wrapping paper (S) whose end is connected to the cylindrical core (P), The wrapping paper passage (Y) is a wrapping paper (S) as shown in the wrapping paper passage (X).
Since the distance between the end of the sheet and the guide 13 provided in the direction of feeding the wrapping paper (S) becomes the shortest, the detecting member 18 is released from the protruding portion 181 of the detecting member 18 and is released. A device that can automatically turn clockwise in FIG. 2 and cause the detection piece 19 to approach the sensor 20 and notify the end state of the wrapping paper (S) as the projecting portion 181 projects onto the wrapping paper base 12. At this time, it is desirable that the driving of the feed roller 11 is stopped by a control means (not shown).

When the end of the wrapping paper (S) is not adhered to the cylindrical core (P), the wrapping paper (S) is continuously transferred by the feed roller 11 and therefore the wrapping paper (S). Needless to say, the end portion of () does not exist on the protruding portion 181 of the detection member 18 and the end state of the wrapping paper (S) can be notified in the same manner as described above.

(Embodiment 2) The wrapping paper end detecting device 100 shown in FIG. 3 corresponds to the wrapping paper end detecting device 1 shown in FIG.
The difference is that an ultrasonic sensor 110 is provided instead of the detection member 18 at the end of the wrapping paper, and the other configurations are almost the same, and the description thereof is omitted.

The function of the ultrasonic sensor 110 is to transmit an ultrasonic wave at least on the ultrasonic path (Z) and to receive a reflected wave of the ultrasonic wave thus emitted, and to detect a wrapping paper (S) which is an object. ), The distance (K) between the object and the ultrasonic sensor 110 is obtained from the time (T) from the transmission of the ultrasonic wave to the reception of the reflected wave and the speed (V) of the ultrasonic wave ( Actually, since it is a reciprocating distance, K = TV / 2), and the distance (K) calculated as described above is the packaging paper path (X) and the ultrasonic sensor 11 in FIG.
When the distance from 0 or more is reached, the end of the wrapping paper (S) can be determined.

It should be noted that it is desirable to set the distance (K) within an allowable range in consideration of the vibration amount of the wrapping paper (S).

Even if the end of the wrapping paper (S) is not adhered to the cylindrical core (P), the end of the wrapping paper (S) moves to a position retracted from the wrapping paper stand 12. Therefore, the distance calculated from the detection result of the ultrasonic waves is larger than the distance (K), and it can be determined that the end of the packaging paper has been detected.

[0030]

According to the present invention described above, the following effects can be obtained.

The roll-shaped wrapping paper end can be reliably detected regardless of whether or not the end of the roll-shaped wrapping paper is connected to the tubular core.

The structure is simple and easy to handle,
It is possible to obtain an excellent device with less risk of failure.
