Abstract

PURPOSE:To speed up transferring collected coins without unpiling collected coins by a method wherein bending of a top lever is adjusted by an adjusting device at a transfer position and a swinging adjustment member is adjusted at a wrapping position. CONSTITUTION:At a position for transferring collected coins, an adjusting bolt 77 is swung to have a top lever 81 and a swing lever 74 pressed, and the top lever 81 is swung to a direction of bending with respect to a shaft 74 as the center of swinging so that height of a roller 84 is adjusted. As a result, the position of a conveyer arm 31 is fine-adjusted and a coin receiver 31a is adjusted so that it comes just below a shutter 84. When a screw 86 is loosened and an adjusting plate 83 is swung at this position, the roller 84 moves so that it is located approximately above a swing shaft 82 of the adjusting plate 83. On the other hand, at a position for wrapping collected coins, height of the roller 84 is adjusted by swinging the adjusting plate 83. That is, the fixing screw 86 is loosened, the adjusting plate is swung in a range regulating a long hole 85, and the coin receiver 31a at the tip of the conveyer arm 31 is fine- adjusted so that it comes to the wrapping position, before the screw 86 is retightened for positioning.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a position adjustment mechanism for a coin receiver in a coin packaging machine.

[Prior art] In recent years, as a coin wrapping machine, Japanese Patent Application Laid-Open No. 62-20832
A coin packaging machine such as that described in Publication No. 9 is widely used.This machine does not use a stacking cylinder, but supports coins vertically by a spiral protrusion provided on the outer periphery of a pair of stacking drums. By rotating the pair of accumulating drums, the position of the accumulated coins is gradually lowered to accumulate a desired number of coins.The accumulated coins are collected in three packages. The receptacles are delivered to a packaging mechanism that is structured around rollers and placed below the accumulating drum, and are packaged.

In this case, the stacked coins are gradually lowered and stacked by the thickness of one coin, and after stacking the number of coins to be packaged, the stacking drum is continuously rotated, and a shutter provided below the stacking drum is moved. is lowered to the top. This position is used as the transfer position for the receiver to be passed to the packaging mechanism below.

On the other hand, the packaging mechanism incorporates a coin receptacle for receiving the accumulated coins at the transfer position. An example of this coin receiver is described in Utility Model Publication No. 56-51444. This is a conveyor arm (conveyor rod) with a coin receptacle (support frame) at its tip that is raised and lowered by a lever consisting of a top lever (?11 moving side front part) and a shift arm (drive side rear part). Receipt of accumulated coins is for handing over.

In this case, the above top lever and shift arm are "<"
They are connected at their ends so that they are bent into a letter shape, and are pulled in the direction of a straight line by a spring and pushed in the direction of bending by an adjustment screw. Then, in the packaging position, the coin receiver is adjusted using the adjustment screw so that it is in the correct position. On the other hand, when the coin receiver is in the coin passing position, the conveyor arm rises and is stopped by the upper regulating member, and at this time, the top lever bends against the biasing force of the spring. It had become. In this state, the coin receiver was accurately positioned at the transfer position, and the yoke when the accumulated coins fell was minimized.

[Problem to be Solved by the Inventionj] According to the conventional coin wrapping machine described above, the hair arm,
Even if there are dimensional variations in members such as the top lever and shift arm, it is possible to accurately position the coin receiver in the transfer position and the packaging position.

However, when the coin receiver is in the passing position,
The top lever is always bent and pulled by a spring. Therefore, when the shift arm moves downward toward the packaging position, the bent lever returns to its straight state. In this case, the accumulated coins are placed on the coin receiver and are in an unstable state with no other support, so the accumulated coins may collapse during the process of returning the lever. Especially when it comes to small diameter coins, the stack of coins tends to collapse.

Further, the time it takes for the accumulated coins to descend from the transfer position to the packaging position is about 0.2 seconds, and the coin receiver drops instantly, which delays the return of the top lever and prevents higher speeds. This drawback could not be improved even by increasing the force of the spring.

This invention was made against this background, and it is possible to accurately adjust the position of the coin receiver, and even in the case of high-speed processing, the receiver can prevent the accumulated coins handed to it from collapsing. The purpose of the present invention is to provide a mechanism for adjusting the position of a coin receiver in a coin packaging machine.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention has a structure in which, after the coins fed out from the rotary disk are accumulated on the accumulation drum, the accumulated coin bones are lowered to the transfer position and are provided on the wrapping roller side. In a coin wrapping machine, the accumulated coin frame is raised to a passing position by driving the accumulated coin tray by a driving means, the tray passes the accumulated coins to the coin tray, and the coins are lowered to a wrapping roller side and wrapped. The driving means is characterized by having the following components.

(a) a conveyor arm that moves up and down together with the coin receiver; (b) a guide means for guiding the conveyor arm; (c)
) a support member that supports the conveyor arm from below; (d) an adjustment plate to which the support member is fixed; (e)
a rotation adjustment member that supports the adjustment plate so that it can rotate within a certain range in a vertical plane and adjusts its rotation position; (f) a lever (g) to which the rotation adjustment member is attached;
a shift arm rotatably supporting the lever in a vertical plane; (h) biasing means for biasing the lever upward; (i)
) Adjustment means for finely adjusting the rotational position of the lever while pressing the lever downward; (j) Rotation means for rotating the shift arm in a vertical plane.

[Function] According to the above configuration, when the receiver is in the passing position, the position of the coin bone can be adjusted by adjusting the degree of bending of the top lever using the adjusting means. Also,
At the packaging position, the position of the coin bone can be adjusted by adjusting the rotation adjustment member.

In this case, even if adjustment is made using the rotation adjustment member at the wrapping position, the receiver can be made to have little effect on the position of the coin bones at the handing position. In other words, the adjustment at the packaging position can be made independently of the adjustment at the receiving and transferring position. Therefore, there is an advantage that only a simple adjustment is required.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the overall structure of a coin packaging machine 1. FIG.

In the figure, the coins accumulated in the hopper 11 are fJ'
The sheets are sent to the rotary disk 13 by the feeding conveyor 12, passed through the sorting passage 14, and are stacked one by one between the stacking drums 15 and 16. That is, the coins are collected in the accumulating drum 15.16
The sheets are accumulated one by one in the space formed by the and the regulating body (the path shown in the figure). On the outer periphery of the accumulating drum 15.16,
Spiral projections 15a, 16a are formed, and the coins are supported by these projections 15a, 16a. In this case, the accumulating drum 15.16 is loaded with 1 coin.
Each time a coin is stacked, it rotates slightly, lowering the coin by the thickness of the stack. That is, the topmost coin is always located at the exit of the sorting passage 14.

The accumulated coins C gradually descend as the accumulating drums 15 and 16 rotate, and as shown in FIG.
．． 16 (FIG. 6(C)).

In this way, when the accumulated coins C reach the top of the shutter 18, the shutter 18 is opened (FIG. 6(d)), and the receiver is passed to the coin frame 31a that has risen from the packaging mechanism section.

In Fig. 1, 18 is a denomination setting dial, which adjusts the width of the sorting passage 14 and the stacking drums 15, 16 according to the denomination.
This is a means to change the interval between.

The packaging mechanism is located under the accumulating drum 15.16.
It is composed mainly of book wrapping rollers 21, 22, and 23, and the stacked coins are wrapped by a paper making 26 formed between a supply roller 24 and a driven roller 25.

The wrapped coins are discharged from the roll chute 27.

Next, Fig. 2 and Fig. 3 are diagrams showing the mechanism related to the conveyor arm, Fig. 2 is a side view, and Fig. 3 is the III of Fig. 2.
-III line arrow 61 is a plan view. In these figures,
Among the three packaging rollers 21, 22, and 23, there is a coin bone 31 provided at the tip of the conveyor arm 31.
A is arranged so that it can appear and disappear.

The conveyor arm 31 is attached to a support 33 so as to be movable up and down by a pair of upper and lower bearings 32 attached to its base end. This bearing section 32 includes three bearings 34a, 34 arranged at equal intervals around a shaft 33.
b, 34c, and is designed to move the conveyor arm 31 up and down along the middle 1!133. A mounting plate 35 is also fixed to the conveyor arm 31.
A pair of bearings 36a and 36b are attached to the mounting plate 35 so as to sandwich the shaft 37 therebetween. Therefore,
The horizontal movement of the conveyor arm 31 is regulated by the shaft 37, and it rotates about the shaft 33 as the shaft 37 moves.

This shaft 33 has its upper and lower ends fixed to an upper connecting member 41 and an unconnected member 42, respectively, and these connecting members 41.
42 is rotatably supported by the shaft 33. Further, a roller 43 is attached to the end of the lower connecting member 41, and the conveyor arm 31 rotates about the shaft 33 by being driven in the horizontal direction by the roller 43 or an arm (not shown). A coin amount 31a provided at the tip of the conveyor arm 31 is adapted to appear between the wrapping rollers 21 and 2223.

At the base end of the conveyor arm 31, a pair of bearings 32.3
2, a notch 45 is provided, and a roller 84 on the top lever 81 side, which will be described later, is fitted into this notch 45. Note that this roller 84 is connected to the top lever 8
It is fixed to an adjustment plate 83 fixed to the tip of the adjustment plate 83.

4 and 5 are diagrams showing the structure of the shift arm 50 and the side link of the top lever 81 for raising and lowering the conveyor arm 31. FIG. 4 is a side view, and FIG. 5 is a plan view.

A horizontal shaft 51 is attached to the base end of the shift arm 50, and a cam roller 52 is attached to the center thereof, so that as the cam 53 in contact with the cam roller 52 rotates, the shift arm 50 rotates in the vertical direction. It has become. The cam 53 is rotationally driven by a camshaft 54, which is connected to a motor shaft 57a via a driven gear 55 and a drive gear 56, and is rotationally driven by a camshaft drive motor. Note that the shift arm 50 is urged downward by a spring (not shown) so as to be in constant contact with the cam 53.

A pulley 58 is also fixed to the motor shaft 57a and connected to an electromagnetic brake 60 via a belt 59.

This electromagnetic brake 60 applies braking to the motor shaft 57a when the accumulated coin amount 31a reaches the transfer position.
This is for holding the coin amount 31a in that position.

A disk (not shown) is fixed to the camshaft 54. This disk has one slit in its circumferential direction. Therefore, by detecting this slit with a sensor, the rotation of the cam and its initial position can be detected.

Next, a pair of support levers 7i72 are attached to the shift arm 50 so as to sandwich it therebetween. That is, an L-shaped support lever 7 is located below in FIG. 5 (front in FIG. 4).
1 is attached, and a longer T-shaped support lever 72 is fixed above it in FIG. 5 (at the rear in FIG. 4). A shaft 73 is attached to the downwardly protruding portions of these support levers 71 and 72, and a rotating lever 74 that rotates about this shaft 73 is attached so as to be sandwiched between the support levers 7172.

The rotating lever 74 is biased clockwise (upward) in FIG. upward movement is restricted.

The above-mentioned top lever 81 is fixed to this rotary lever 74. A shaft 82 is attached to the tip of the top lever 81.
is fixed, and a triangular adjustment plate 83 is rotatably attached to this shaft 82. A roller 84 that engages with the notch 45 of the conveyor arm 31 is attached to the adjustment plate 83 . Further, a long hole 85 is formed in the adjustment plate 83, and the adjustment plate 83 is tightened to the top lever 81 by a screw 86 fitted into the long hole. Thereby, the receiver can finely adjust the position of the coin amount 31a at the transfer position and the packaging position.

FIG. 7 is a side view for explaining position adjustment of the amount of coins at the transfer position and the packaging position.

First, when the accumulated coin bones are in the passing position (the upper position in FIG. 7), turn the adjusting bolt 77.

The height of the roller 84 is adjusted by pressing the prepper 81 and the rotating lever 74 and rotating the top lever 81 in the bending direction (downward in the figure) about the shaft 74. As a result, the position of the conveyor arm 31 shown in FIG. 2 is finely adjusted, and the amount of coins 31a is adjusted to be directly below the shutter 18.

At this position, when the screw 86 is loosened and the adjustment plate 83 is rotated, the roller 84 moves within the range shown in the figure. Here, the roller 84 is positioned almost directly above the rotation shaft 82 of the adjustment plate 83. At this time, if the distance between the center of the roller 84 and the center of the shaft 82 is R, and the rotation angle of the adjustment plate 83 is 2θ, then the vertical movement amount D1 of the roller 84 is DI=R−Rcos2θ... (1) becomes.

On the other hand, at the stacked coin wrapping position (lower position in FIG. 7), the height of the roller 84 is adjusted by rotating the adjustment plate 83. That is, after loosening the fixing screw 86 of the adjustment plate 83 and rotating the adjustment plate 83 within the range regulated by the long hole 85, fine adjustment is made so that the coin amount 31a at the tip of the conhair arm 31 is at the wrapping position. , tighten the screw 86 again to perform positioning.

In this case, assuming that the angle between the roller 84 and the vertical line passing through the respective centers of the roller 84 and the shaft 82 is a, the vertical movement flD2 of the roller 84 can be determined as follows.

First, based on the case where the screw 86 is located in the center of the long hole 85, the change in the height direction d1 when adjusted to the A side in the figure,
Calculating the height change d2 when adjusting to the B side, d l = Rcos (a - e ) - Rcosad
2 = Rcos(a 10) R
It becomes cosa. Therefore, by taking these differences, the change in the height direction fit D 2 is: D 2 = R1 cos (a - θ) - cos (a +
-8)) --(2).

Here, if R=3Q mm and θ=8°a-40°, then Dl=0.3mm and D2=5.4mm. That is, it can be seen that while the change in the height of the amount of coins at the transfer position is almost negligible, it is possible to adjust the height of about 5 mm at the packaging position. Therefore, by adjusting the amount of coins using the adjusting bolt 77 at the transfer position and then adjusting the height by rotating the adjusting plate 83 at the wrapping position, the positions can be adjusted almost independently at both positions. Moreover, since the top lever 81 does not return from the bent position, there is no risk that the accumulated coins will collapse due to the return operation.

After such position adjustment, the actual coin wrapping operation can be performed.

FIG. 6 illustrates the coin transfer process in this practical example.

In FIG. 5A, the shutter 18 is located directly below the stacking drums 15 and 16 and is in a closed state.

In addition, the accumulated coins C are located at a fairly high position, and the amount of coins is 31
a is at the initial position.

The figure (b) shows a state in which the coin amount 31a has risen to the transfer position and is on standby. At this time, the electromagnetic brake 60 is on.

Figure (c) shows the state in which the stacking drums 15 and 16 have rotated once and the stacked coins have fallen onto the top of the stack 18. As a result, the preparation for receiving and transferring the accumulated coins is completed, and at this point, the electromagnetic brake 60 is turned off.

Figure Cd> shows a state in which the coin amount 31a supports the accumulated coins C and lowers them to the packaging position. Packaging processing is executed in this state.

According to the present embodiment, in the transfer process for such accumulated coin amounts, the accumulated coin amount 31a can be accurately positioned at the transfer position and the packaging position.

[Effects of the Invention] As explained above, the present invention eliminates the return operation of the lever and makes it possible to adjust the position of the accumulated coin amount almost independently and accurately at the transfer position and the packaging position. , the following effects can be obtained.

(1) Since the positioning accuracy of the amount of coins at both of the above positions is high, the coin receiving and passing process can be performed smoothly.

(2) Since there is no return action of the lever, there is no need to destroy the accumulated coins. This is particularly effective for small diameter coins.

(3) Since the time required for the (a) return operation of the lever is eliminated, the amount of accumulated coins can be increased to speed up the handing process.
