Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin wrapping machine, and more particularly to a guiding device for wrapping paper for wrapping coins.

Conventionally, a coin wrapping machine has been equipped with wrapping rollers 30, 32, and 33 that wrap wrapping paper 2 around the circumferential side of a predetermined number of stacked coins 1, as shown in the main plane in FIG. The wrapping paper 2 is placed in the coin wrapping unit 4 having a wrapping supply roller 5, 6.
The wrapping paper 2 is fed along the wrapping paper guide members 7□ and 72 which are curved by
Tension is applied by the tight contact between the stacked coins 1 and the stacked coins 1, and the coins are cut by being pressed against the cutting edge of the cutter 8 installed between the coin wrapping section 4 and the wrapping paper supply rollers 5 and 6. is generally known.

In order to ensure that the free end of the fed wrapping paper 2 in the traveling direction, that is, the tip of the wrapping paper, enters the coin wrapping section 4 smoothly, the wrapping paper is placed near the wrapping paper section 4a of the wrapping section 4. A wrapping paper guide member 9 is fixed at a distance from the paper guide member 7 □, and the leading end of the wrapping paper 2 fed by the wrapping paper supply rollers 5 and 6 is smoothly attached to the wrapping paper 4a of the coin wrapping section 4. I'm trying to get them to enter.

Generally, the wrapping paper guide member 9 has a wider passageway on the entrance side than the wrapping paper guide member 72, and the coin wrapping section 4
Although the wrapping paper guide member 9 is installed so that it is narrow on the side, the installation position of the wrapping paper guide member 9 is the first position. Due to the curl of the wrapping paper 2 being sent, the wrapping paper 2
is reversed as shown by the chain line and is no longer sent to the coin packaging section 4.

In addition, if the installation position of the wrapping paper guide member 9 is close to the wrapping paper guide member 7 □ side as shown in the B position in Fig. 1, and the inside passage on the entrance side is in a narrow position, the feeding by the curling as described above will occur. However, on the other hand, when the free end of the wrapping paper 2 is stuck between the wrapping roller 3 □ of the coin wrapping section 4 and the stacked coins 1 and tension is applied, the wrapping paper guide member The angle θ at which the wrapping paper 2 hits the cutter 8 becomes large due to the entrance edge 9a of the wrapping paper 2, and therefore, the cutting is not performed smoothly and poor cutting is likely to occur.

Therefore, if this wrapping paper guide member 9 is fixedly installed at an intermediate position between positions A and B in FIG. 1, the number of times that the wrapping paper 2 cannot be fed due to curling will be reduced compared to the position A in FIG. 1. Also, although the number of occurrences of wrapping paper cutting defects is smaller than in the position B in FIG. 1, both wrapping paper feeding failure and cutting defects occur.

Therefore, the current situation is to select an intermediate position where the number of occurrences of these defects is as small as possible, and to fix the wrapping paper guide member 9 at that position.

As described above, in the conventional coin wrapping machine, it is inevitable that the wrapping paper 2 is curled up and cannot be fed and the wrapping paper is cut incorrectly.

In view of this, the present invention has been made for the purpose of providing a wrapping paper guide device for a coin wrapping machine that eliminates the drawbacks of the above-mentioned prior art. It has a curved surface shape that bends in the same direction as the guide member, and the trailing portion toward the rear end has a guide surface shape that smoothly continues to the curved surface shape. The wrapping paper is supported on a shaft so as to be able to swing freely, and the wrapping paper guide surface is moved from the wrapping paper guide position where the tip of the wrapping paper is guided toward the wrapping paper entrance of the coin wrapping section to the wrapping paper cutting position when the wrapping paper is under tension. It is characterized in that it is formed so that it can freely retreat against the urging of the urging means.

Hereinafter, the present invention will be explained with reference to the embodiments shown in FIGS. 2 and 3, in which parts common to those in FIG. 1 are given the same reference numerals.

In the present invention, bearing members 12.12 provided at the upper and lower bases of the wrapping paper guide plate 11 are rotatably attached to the shaft 10 of the wrapping roller 3□, which is fixed in position and located in the wrapping paper portion 4a of the coin wrapping section 4. Supported.

The wrapping paper guide plate 11 and the bearing member 12.12
Thus, a wrapping paper guide member as an example of the present invention is constructed.

The wrapping paper 4a is between the fixed-position wrapping roller 3 and the stacked coins, and when the leading edge of the wrapping paper 2 enters the wrapping paper 4a, the wrapping roller 33 does not hold the stacked coins. This is while the coins are being moved towards the wrapping rollers 31.32 or immediately after the stacked coins are pinched by the wrapping rollers 31.3° and 33.

Further, a spring 14 is suspended between an arm 13 extending to one end of the shaft bearing member 12 and a fixed part of the coin wrapping machine, so that the starting end of the wrapping paper guide plate 11, that is, the leading end 11a is placed on the wrapping paper guide member 7□ side. energized.

The tip end 11a of the wrapping paper guide plate 11 is a curved surface that is curved almost parallel to the curved inner surface of the wrapping paper guide member 7, and the rear end of this guide plate 11 is connected to a wrapping roller whose position is fixed. The trailing portion located near the circumferential surface of 3□ and following the curved surface toward the rear end is a guide surface that smoothly follows this curved surface, and the area from this tip 11a to the rear end is the wrapping paper guide surface. The interval of the wrapping paper path A formed between the wrapping paper guide surface of the wrapping paper guide plate 11 and the wrapping paper guide members 7 and 72 is determined by a stopper 19 fixed to the machine body (not shown). It has become.

In this embodiment, a cam 1 is provided on the outer periphery of the bearing member 12.
5 is formed, and an actuating piece 16 of the switch S is disposed corresponding to this cam 15.

This switch S is turned on when the actuating piece 16 is pressed by the cam 15, and the switch S is turned on when the wrapping paper guide plate 11 is pressed by the tension of the wrapping paper 2, that is, when the wrapping paper guide plate 11 is pressed by the tension of the wrapping paper 2. When it is detected that the paper has been fed normally, the wrapping paper supply rollers 5 and 6 that supply the wrapping paper 2 made up of the wrapping paper roll 2' are stopped.

In the figure, 17 is a presser piece attached to the cutter 8, which is used to make the wrapping paper 2 follow the inner surface of the wrapping paper guide member 7□, and 18 is a shaft that supports the wrapping paper guide member 7 so that it can be opened and closed. Therefore, in the event that the wrapping paper 2 jams, it can be easily removed.

Next, the operation of the above embodiment will be explained.

The wrapping paper 2 pulled out from the wrapping paper roll 2' passes between wrapping paper supply rollers 5 and 6, and its tip is positioned at the cutter 8. When driven in the direction of the arrow in synchronization with the completion of supply of stacked coins 1, the leading edge of the wrapping paper 2 is fed along the inner surface of the wrapping paper guide member 7□ from the position of the cutting edge of the cutter 8, and soon the leading edge of the wrapping paper 2 passes through the wrapping paper. It passes through the wrapping paper path A formed by the paper guide members 71, 7□ and the wrapping paper guide plate 11 located at the wrapping paper guide position, and reaches the entrance 4a of the coin packaging section 4, and the wrapping paper is wrapped as shown in FIG. It is stuck between the roller 3□ and the stacked coins 1.

When the tip of the wrapping paper 2 is pinched in the coin wrapping section 4, the wrapping rollers 3□, 3□ in the coin wrapping section 4.

Due to the difference between the rotational speed of 33 and the rotational speed of the wrapping paper supply rollers 5 and 6, the tip of the wrapping paper is sent to the wrapping rollers 3i, 32, and 33 that rotate and pinch the stacked coins, as shown in the third figure. Tension is applied to the slackened trailing portion of the wrapping paper 2, and this tension causes the wrapping paper guide plate 11 to move away against the ribs 14 as shown by the dotted line in Figure 3, thereby releasing the tension in the wrapping paper 2. Allow.

When the wrapping paper guide plate 11 moves back to the wrapping paper cutting position due to this tension, the bearing member 12 at its base also rotates.
When the cam 15 presses the operating piece 16 of the switch S, the switch S is activated, the driving of the wrapping paper supply rollers 5 and 6 is stopped, and the wrapping paper 2 is pressed against the cutting edge of the cutter 8 due to the tension, and is cut to a fixed size. is cut off.

Note that the leading end of the wrapping paper on the wrapping paper roll 2' side is stopped at the position of the cutter 8.

At the same time as cutting, the trailing portion of the wrapping paper 2 is further rolled up into the coin wrapping section 4, wrapped around the circumferential surface of the stacked coins 1, and then the upper and lower ends are folded in by a winding needle (not shown) as is known in the art.

After wrapping is completed, one wrapping roller 33 retreats as shown by the arrow, and the support member supporting the stacked coins 1 moves away to release the wrapped coins.

On the other hand, at the same time as the wrapping paper 2 is cut, the pressing force of the wrapping paper guide plate 11 is released, so that the wrapping paper guide plate 11 returns to the solid line position in FIG. A wrapping paper path A is formed between the wrapping paper guide member 7 and the cam 15 of the bearing member 12 is disengaged from the operating piece 16 of the switch S to return the switch S to its original state.

Note that when the wrapping paper guide plate 1] is moved back, the coin wrapping section 4
The rear end portion of the wrapping paper 2 that has been rolled up is progressing while contacting the wrapping paper guide surface of the wrapping paper guide plate 11, and during this progress, the rear end of the wrapping paper 2 may be wrapped around due to curling. However, the return movement of the presser piece 17 and the wrapping paper guide plate 11 in the direction of the wrapping paper guide members 7□, 7□ and the formation of the wrapping paper path A after the return prevent this.

As explained above, in the present invention, the wrapping paper guide member that guides the wrapping paper toward the wrapping paper entrance of the coin wrapping section is attached to the rotating shaft of the wrapping roller, which is fixed in position, in order to be able to move forward and backward with respect to the wrapping paper guide member. Since the wrapping paper guide member is swingably supported on a shaft and positioned at the wrapping paper guide position by the urging means and the stopper, a suitable wrapping paper path is formed between the wrapping paper guide member and the wrapping paper guide member. Until the wrapping paper that is drawn out and fed by the wrapping paper supply roller reaches the coin wrapping section, the leading edge of the wrapping paper can be properly guided, and the leading edge of the wrapping paper will stick to the coin wrapping section and the wrapping paper will not stick to the coin wrapping section. When a section is under tension, it resists the force and retreats due to the tension, so it can be pressed against the cutter at an optimal angle.Therefore, when feeding wrapping paper, there is no jamming due to curling, and the wrapping paper is always fed smoothly. While cutting, the tension of the wrapping paper is not disturbed during cutting, and an excellent effect can be obtained in that the wrapping paper can be pressed against the cutter and cut well.

In this embodiment, a switch is activated when the wrapping paper guide member is pressed, and the wrapping paper supply roller is controlled by this switch. You may also do so.
