Description

[Detailed Description of the Invention] This invention relates to a wrapping paper guide device in a wrapping roller section of a coin wrapping machine.

Generally, coin wrapping machines have a type in which a predetermined number of accumulated coins that have been counted and stacked in a stacking cylinder are received by a support rod and introduced vertically between wrapping rollers, and the accumulated coins in the stacking cylinder are stacked up and down. There is a type in which the paper is held by a clamping rod, and when the stacking cylinder is opened, it is transported laterally and guided to the packaging roller section.

In any of the above types, fixed or movable wrapping paper guide plates are provided on the sides of the wrapping rollers to prevent the wrapping paper from deviating outward from between the wrapping rollers during the winding operation of the wrapping paper.

The above-mentioned movable wrapping paper guide plate is supported by the packaging roller shaft, and is configured to rotate around the shaft along the outer peripheral surface of the packaging roller, and the movable wrapping paper guide plate is configured to rotate along the outer peripheral surface of the packaging roller and the guide plate. There is some gap between them.

Therefore, depending on the state of the curl of the wrapping paper, the leading edge of the wrapping paper may get stuck in this gap while the wrapping paper is in progress, which is inconvenient.

As a solution, a method has been proposed in which the intermediate portion of the wrapping paper roller is configured to have a small diameter, and the core portion is fitted with the Ea conductor provided on the wrapping paper guide plate to eliminate this problem.

(Refer to Japanese Utility Model Publication No. 50-26676.) However, due to the construction, the wrapping paper cannot be guided over almost the entire circumference of the accumulated coins.

In addition, in the above device, when the wrapping paper is sent to the wrapping roller section, it is not possible to reliably guide the protruding V-shaped tip of the wrapping paper at the introduction section, so the wrapping paper has a tip that is connected to the wrapping roller and the accumulated coins. It is sent to the packaging roller section in an unstable floating state until it is pinched between the surrounding surface.

This invention was made in consideration of the above-mentioned circumstances, and its purpose is to ensure that the wrapping paper is stably fed into the wrapping roller section without getting into the gaps at various places in the wrapping roller section, and To provide a wrapping paper guide device having a simple configuration and capable of guiding wrapping paper over most of the circumferential surface of a coin without any trouble even if the diameter of a coin to be wrapped changes.

An embodiment of this invention will be described below with reference to the drawings.

1.2 are eleventh and second wrapping rollers which are provided in order from the paper supply side of the wrapping paper 21.

Reference numeral 3 denotes a third packaging roller, which is configured to be largely rotated around an axis γ.

This allows the coins to be moved out of the way when the accumulated coins accumulated in the stacking cylinder (not shown) are held by upper and lower clamping rods (not shown) and transported laterally toward the first and second packaging rollers. This is because when the accumulated coins move, they are rotated so as to follow the accumulated coins.

Each of these packaging rollers 1.2.3 has a respective rotation axis 4
．． 5.6, and rotates counterclockwise with power transmitted by a gear (not shown).

Further, between the first and second wrapping rollers 1 and 2, crimping claws 9° 9' are provided for crimping the accumulated coins that have been conveyed.

Furthermore, grooves 26 and 27 are formed along the outer periphery at substantially intermediate positions of each of the first and second packaging rollers 1 and 2, and are configured to have small diameter portions.

A guide plate guide 20 is fixed to the outer peripheral surface above the small diameter portion (groove 26) of the first packaging roller 1 so as to protrude in the radial direction, and is configured to guide a movable guide plate 16, which will be described later. ing.

Also, one end (fixed end) is fixed to a fixed plate 24 located on the supply side of the wrapping paper 21 with respect to the first wrapping roller 1, and the other end (free end) is connected to the eleventh second wrapping roller 1°2. A plate-shaped elastic body 25 is provided so as to be able to move in and out of the layer 26.27 facing the valley groove 26.27 of the layer 26.27.

The shape of the plate-like elastic body 25 is approximately S-shaped as shown in the figure, and its horizontal axis is smaller than the width of the grooves 26 and 27.

Furthermore, regarding the plate-shaped elastic body 25, a guide plate 22 is provided on the opposite side of the first wrapping roller 1 to guide the wrapping paper 21 so as to sandwich the plate-shaped elastic body 25.

The fixed end of this guide plate 22 is fixed by a guide block 23 as shown.

Guide plate receivers 12 and 12' are rotatably fitted onto the shaft 5 at both ends of the second packaging roller 2, and a movable guide plate 28 is attached to the guide plate receivers 12 and 12'. .

The movable guide plate 28 is supported by the spring 11 which pulls the guide plate holder 12 counterclockwise. A stopper 10, which is fixed to a machine frame (not shown) and is in contact with a guide plate holder 12, prevents the opening beyond that shown in the drawing.

The third packaging roller 3 has an arm 8.8 that rotates around the shaft 7.
' supports the rotating shaft 6, and as mentioned above, the shaft 7
It is configured to be movable to the first and second packaging rollers 1°2 side centering on the packaging rollers.

On the arm 8.8', a guide plate holder 13 and an auxiliary guide plate 14 are located outside the movable wrapping paper guide plate 28 when the third wrapping roller 3 moves to the position where the accumulated coins A are clamped. It is installed like this.

Further, guide plate holders 15 and 15' to which a movable wrapping paper guide plate 16 is attached are rotatably fitted to the rotating shaft 6.

A spring 19 is tensioned on this guide plate holder 15', and a pin 18
Rotation is restricted at the position.

A roller 17 is provided on the guide plate 16 attached to the guide plate receiver 15° 15', and the third wrapping roller 3 collects the accumulated coins A.
It is configured to move along the guide plate guide 20 when it comes to the position where it is to be clamped.

Further, 21 is a wrapping paper, and when it is fed from a paper feeding position (not shown) to the wrapping roller section, its tip 21a is sandwiched between the plate-shaped elastic body 25 and the guide plate 22, and then
Furthermore, it is fed along the plate-like elastic body 25 to the packaging roller section.

With the above structure, the accumulated coins A are held between the upper and lower holding rods (not shown) and transferred to the first and second wrapping rollers 1,
2, and by the time it reaches the position shown in FIG. It is sandwiched between the plates 22, and then the plate-shaped elastic body 25
, and reaches the position shown in Fig. 2.

In this case, since the tip end 21a of the wrapping paper 21 is guided by the plate-like elastic body 25 as described above, the gap between the eleventh and second wrapping rollers 1 and 2 is There will be no troubles that could lead to this.

Following the state shown in Fig. 2, the state shown in Fig. 3 occurs, and the accumulated coin A
is held between the three wrapping rollers 1.2.3 and the wrapping operation is started, the plate-like elastic body 25 is pushed by the accumulated coins A and deforms as shown in FIG. 3, changing the size of the coin diameter. It adapts to the outer periphery regardless of the situation, and troubles such as the wrapping paper getting caught in the gap between the second wrapping roller 2 and the movable guide plate 28 or being sent out to the outside of the wrapping roller part do not occur.

In the above embodiment, a coin packaging device is described in detail in which the accumulated coins A are held between upper and lower clamping rods and conveyed laterally to the packaging roller section, but the present invention has a system in which accumulated coins are received by a support rod. It is also applicable in exactly the same way to a type of conveyance from the vertical direction to the packaging roller section.

As explained above, the present invention uses the above-mentioned plate-shaped elastic body with one end fixed as a guide member to guide the leading end of the wrapping paper to the circumferential surface of the accumulated coins. Because it can be inserted and removed, there is no problem in wrapping even if the diameter of the coin to be wrapped changes, and the wrapping paper can be guided from the introduction part of the wrapping paper to most of the wrapping rollers, so the wrapping paper can be easily wrapped. The paper can be reliably wrapped around the outer circumference of the coin, and the structure is simple.

Furthermore, in the case of the above-mentioned type in which the coins are conveyed vertically to the wrapping roller section, it is possible to wrap the plate-like elastic body around almost the entire circumference of the coin, so that the results are even better.
