Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a coin packaging mechanical device that counts coins and wraps a predetermined number of stacked coins in a rod shape with a packaging material.

(Prior Art) As a prior art, a wrapping device for a coin wrapping machine is known as disclosed in Japanese Patent Application Laid-Open No. 54-31382, which was invented by the same applicant as the present invention. In other words, "an adjustment member that is selectively positioned by a denomination setting mechanism according to the designated denomination by the coin denomination designation operation; and an actuation mechanism that engages with the adjustment member to determine the operating position; A wrapping device for a coin wrapping machine, characterized in that the release position of the wrapping mechanism operated by the operating mechanism is determined in accordance with the wrapping denomination so that it is slightly larger than the diameter of the coin to be wrapped.'' be.

(Problems to be Solved by the Invention) One of the problems that tend to occur during the operation of the above-mentioned packaging machine is that the wrapping paper is not fed properly. In that case, the wrapping paper may not be wound properly between the multiple wrapping rollers, and may become mushy or curled up in a diagonal direction, or the wrapping paper may be torn. There is a risk of In addition, if the stacked coins to be wrapped do not exist normally due to an abnormality in the processing mechanism before packaging such as the shutter lock or the stack, the abnormality detection means, especially the presence or absence of a wrapping paper cut detection signal, The occurrence of an error was determined by a detection means, and the error was notified through an alarm or indicator light, while the mechanism operation was automatically stopped. However, this automatic stop is also due to inertia, especially if the cam of the crimping mechanism rotates, the crimping arm that holds the crimping claw also tries to be introduced into the packaging mechanism and raised and lowered by both the horizontal and vertical operating levers, which prevents stacking. If a coin is hot, the crimping claws forcefully press it from above and below, which can cause the coin to scatter inside the machine, or cause the coin to come into direct contact with the surface of the packaging roller, causing damage.

In addition, if a start or clear command is given in order to recover, the continuation of the rotation of the packaging operation cam causes the crimping arm to operate and attempt to move in and out of the packaging mechanism, causing the above-mentioned failure. .

(Means for Solving the Problems) Therefore, in order to eliminate these obstacles, the present invention provides a method for distributing a weight around which a packaging material is wound by a plurality of packaging rollers including at least one movable packaging roller. A coin packaging machine equipped with a crimping arm having a crimping claw that is moved from a predetermined standby position to a crimping position and activated to crimp stacked coins, comprising: an abnormality detection means for detecting the occurrence of an abnormality; This object is achieved by comprising a means for inhibiting operation of the crimping arm to hold it in a standby position, and a control section that operates the operation inhibiting means based on a detection signal from the abnormality detecting means.

5, it detects that the paper is in a tensioned state and sends an ON signal to the control unit (not shown), then detects that the wrapping paper P has been cut by the cutter 25, and sends an OFF signal to the control unit (not shown). The controller is configured to send a signal to the controller.

The upper and lower pair of crimping arms 26, 27 are connected to the upper and lower pair of opposing crimping claws 26', 27' (26, 27, and 2).
6' and 27' overlap each other in the drawing) at their respective tips.

The respective crimping arms 26 and 27 are moved close to each other between the packaging rollers 3, 4, and 5 together with the respective crimping claws 26' and 27', and are separable from each other, and the rear ends of the crimping arms 26 and 27 are vertically attached to the packaging base 14. center axis 28
and a guide shaft 29, which will be described later, so as to be vertically movable.

Further, each of the crimping arms 26 and 27 is urged up and down by a spring (not shown) at the rear end so as to approach each other.

Further, each of the crimping arms 26 and 27, together with the crimping claws 26' and 27', is connected to the packaging roller 3,
4 and 5, the rear end of each is connected to a central axis 28, and a roller 32 is attached to one end around the central axis.
The rotary member 30 is supported rotatably in the horizontal direction about a central shaft 28 by a guide shaft 29 vertically provided at the other end of the rotary member 30 .

Note that each of the crimping arms 26 and 27 is biased by a spring 31 at the rear end so as to move forward between the packaging rollers 3, 4, and 5.

One side of the horizontal actuation lever 33 for the crimping arm comes into contact with the roller 32 of the rotating member 30 .

The horizontal actuating lever 33 for the crimping arm is rotatably supported by a shaft 34 vertically installed on the cam bracket 15 adjacent to the packaging base 14, and is rotated in a reverse direction in FIG. Since it is biased clockwise, the roller 36 at the other tip is configured to come into contact with the surface cam 35, which is made up of large diameter and small diameter parts and is fixed to the horizontal shaft 19 in the cam bracket 15. .

Accordingly, the present invention is provided with a means for preventing the crimping claws 26', 27' from coming into contact with and separating from the horizontal operating lever 33 for advancing to the crimping position. This blocking means is, for example, a stopper-in (blocking member 40), and as shown in FIG. (dot-dashed line)
provided on a rotating plate 41 that is pivotally supported by a shaft 43 of 2;
The rotating plate 41 is a plunger 47 of a solenoid 46.
It is connected with.

Normally, stacked coins are supported by a support rod provided on a conveying arm, and the wrapping paper is transferred between wrapping rollers 3, 4, and 5.
When the wrapping paper P is properly wrapped, the wrapping paper P is fed between the paper feed roller 22, the driven roller 23, and the wrapping rollers 3, 4, and 5, and is in a tensioned state, and the paper cut detection plate 38 is pressed by a spring or the like (not shown). It is rotated counterclockwise against the resistance, and the interlocking detection device (not shown) sends an ON signal to the control unit (not shown).

Furthermore, the wrapping paper P that is fed between the paper feed roller 22, the driven roller 23, and the packaging rollers 3, 4, and 5 and is in a tensioned state is promptly cut by the cutter 25, so that the paper breakage is detected again. The plate 38 is rotated clockwise by a spring or the like (not shown), and an OFF signal is transmitted from an interlocking detection device (not shown) to a control unit (not shown).

In addition, if there is a wrapping paper cut, a jam, a paper feed failure, a paper cut failure, or an abnormality occurs in the front stage of the wrapping mechanism and the piled coins are not normal, the edge cut paper cut detection plate 38 will not rotate, so it will be linked to this. A detection device (not shown) detects that the control unit (not shown) is
It is designed not to transmit ON-OFF signals.

Subsequently, by rotation of the horizontal shaft 19 in the cam bracket 15, the surface cam 35, which is fixed to the outer horizontal shaft 19 and is in contact with the roller 36 at the tip of the horizontal actuating lever 33 for the crimping arm, changes from the large diameter portion to the small diameter portion. Rotate to the end.

Therefore, the horizontal actuating lever 33 for the crimping arm is pulled by the spring 37 and rotates counterclockwise in FIG. 1 about the shaft 34 vertically disposed on the cam bracket 15.

The other side of the rotating horizontal operating lever 33 for the crimping arm is in contact with the rotating member 30, which has a roller 32 at one end, and rotates around the central axis 28. 28 and a guide shaft 29 vertically installed at the other end of the rotating member 30, the crimping arms 26, 27 are pulled by the springs 31 of the crimping arms 26, 27, Rotate clockwise.

In this way, the crimping arms 26 and 27 having the crimping claws 26' and 27' move from the standby position to the crimping position and start the crimping operation.

However, an abnormality occurs and the aforementioned detection device (not shown) is turned on normally by the control unit (not shown).
If the OFF signal is not transmitted, the control unit attracts the plunger 47 by a drive unit 46 such as a solenoid, rotates the rotating plate 41 around the shaft 43 against the spring 48, and causes the blocking member 40 to protrude. to lock the horizontal operating lever 33 in the standby position.

In other words, even when the surface cam 35, which the roller 36 at the distal end abuts on, rotates from the large-diameter portion to the small-diameter portion, the horizontal actuation lever 33 for the crimping arm has the crimping claw 26',
Together with the crimping arms 26 and 27 having 27', they are locked in the standby position by the blocking member 40.

At the same time, the control unit (not shown) notifies the abnormality via a display unit (not shown) or the like.

In this embodiment, an abnormality is detected based on the presence or absence of a signal from a detection device (not shown) linked to the paper cut detection plate 38, but it is also possible to detect the presence or condition of packaging materials, stacked coins, etc. The abnormality may be detected by a known detection means such as a shutter lock detection device (not shown), or these may be used in combination.

Further, in this embodiment, the protruding position of the blocking member 40 for locking the crimping arms 26 and 27 was on the rotation locus of the horizontal actuation lever 33 for the crimping arms. 26, 27, and may be on the rotation locus of the rotation member 30. (Not shown) Furthermore, as an embodiment, contrary to the previous embodiment, the blocking member 40 is projected in advance to a position where it locks the horizontal actuation lever 33 for the crimping arm as described above, etc. If there is no abnormality due to an ON-OFF signal etc. from a detection device (not shown) linked to the detection plate 38, a drive unit 46 such as a solenoid is activated.
Then, the blocking member 40 may be released from the retracted state.

Further, the other embodiment shown in FIGS. 3 and 4 includes a driving unit 46 having a motive power instead of the solenoid, a rotating plate 41 interlocked with the driving unit 46, and a blocking member 4, such as a roller shown in the drawing, attached to the rotating plate 41 and a lever 52 attached thereto.
