Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin packaging machine, and more particularly to an improvement in a shortage detection device capable of detecting a shortage in the number of coins to be wrapped.

A strip of wrapping paper is wrapped around a certain number of stacked coins, and the protruding parts of the wrapping paper that protrude from both ends of the stacked coins are folded in with a winding needle, and the folded edges are used to hold down both ends of the stacked coins. In a coin wrapping machine that performs wrapping, a cam moves the winding needle up and down.

By the way, the packaging position of stacked coins is such that the lower end or the center in the vertical direction is a fixed position, so if the stacking height is changed by changing the denomination or the number of coins, the height of at least one end of the stacked coins will change. position changes.

Therefore, the cam that moves the winding needle up and down has a maximum height cam surface that allows the winding needle to start at a position that is sufficiently far from the end surface of the coin so that the end of the wrapping paper of the stacked coins with the maximum stacking height can be folded. and a cam surface with a minimum height at which the winding needle can fully move at position 1 where it contacts the end surface of the coin so that the end of the wrapping paper of the stacked coin with the minimum stacking height can be folded.

Therefore, the movement of the winding needle always starts its vertical movement from the fixed starting position mentioned above, and the winding needle always starts moving up and down from the above-mentioned fixed starting position, and is at the position 1 where it contacts the end surface of the stacked coins.
Move with.

Therefore, the movement stroke of the winding needle changes depending on the height of the stacked coins.

On the other hand, there is a lack of coin quantity detection device that detects a shortage of coins due to insufficient supply, coins sticking out, coins collapsing, etc.
It was constructed with a switch installed on a horizontally swinging arm that horizontally moves the winding needle from the outside of the packaging position to the packaging position, but does not move vertically.

When this horizontal swinging arm and the winding needle attachment arm, which moves together in the horizontal direction and moves up and down independently in the vertical direction, move excessively beyond the end surface of the stacked coins, this switch is activated. It has become.

However, since the height position of the end face of the stacked coin changes depending on the height of the stacked coin, this switch was made to be able to move up and down on a horizontal swinging arm, and the switch was moved up and down according to the scale attached to the fixed position on the side of the switch. It is designed to be moved up and down and then screwed down.

However, this lack of coins detection device does not have a standard mechanism for determining the position of the switch, and therefore, at the manufacturing stage, various coins of the stacking height to be wrapped or cylinders of the same height are prepared and stacked at the wrapping position. The method of positioning a coin or cylinder, bringing the winding needle into contact with its end face, determining the position of the switch based on the position of the winding needle attachment arm at that time, and sequentially marking the scales, is the so-called spot matching method. I can't do it.

Further, when a user uses a coin wrapping machine manufactured and sold in this manner, it becomes difficult to position the switch if the scale disappears.

Furthermore, if the operator forgets to adjust the switch 11 and wraps low stacked coins with the switch 11 placed in the position for high stacked coins, the winding needle attachment arm presses the switch excessively, causing breakage of the switch.

Furthermore, even if the switch is not damaged, the switch prevents the winding needle from moving up and down, making it impossible to fold the end of the wrapping paper.

The present invention eliminates the drawbacks of the conventional ones mentioned above,
It is an object of the present invention to provide a number shortage detection device for a coin packaging machine that can easily and reliably detect a shortage in the number of hardened coins.

The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 1 schematically shows a coin packaging machine to which a shortage detection device according to the present invention is applied. It includes a coin shaking section 1 that arranges a fixed number of coins in a piled state, and a stacked coin wrapping machine that falls from the coin shaking section 1. A plurality of wrapping rollers 2 that receive coins in the center, rotate the stacked coins by sliding on the surface thereof, and wrap wrapping paper cut to a predetermined length by a cutter around the circumferential surface of the stacked coins.
. The stacked coin support device 7 receives and holds the lower end of the stacked coins received by the wrapping paper winding device 6, holds it during the wrapping period, and then leaves after wrapping is completed and discharges the stacked coins to the delivery section. The devices are driven by means such as cams and gears in the drive system with respective timings determined.

The wrapping paper winding device 6 has an upper winding arm 8 and a lower winding needle arm 9, and the bent ends of these arms 8 and 9 face toward the wrapping paper winding device 3. The above-mentioned winding needles 4 and 5, each having a U-shape, are attached to the section with their tips facing each other.

The upper and lower winding needle arms 8, 9 are pivoted at their base ends to support shafts (not shown) so that they can slide vertically.

These two support shafts (not shown) use one of them as a fulcrum to swing the reel fishing arms 8, 9 in the horizontal direction, and the reel fishing hooks 4,
5 is moved from the outer position of the wrapping rollers 2, 2, 2 toward the wrapping position for wrapping the wrapping paper around the stacked coins, and at the wrapping position, the winding needles 4, 5 approach each other to fold the edges of the wrapping paper. When the winding needles 4 and 5 move away from each other, the winding needles 4 and 5 are moved out.

Cam followers 10.11 projecting laterally are provided at the proximal ends of the upper and lower winding needle arms 8, 9, respectively.

On the other hand, the sides of the reeling fishing arms 8 and 9 are pressed against the respective cam followers 10.11 to apply a predetermined vertical stroke to the reeling fishing arms 8 and 9, and the wrapping paper is wound. Disc cams 12 and 13 for performing the closing motion are attached to a support shaft 14 in the vertical direction.

These disk cams 12.13 are formed with uneven cam surfaces 15.16 for giving the stroke, and rotate following the rotation of the support shaft 14, so that the cam surfaces 15.16 rotate.
The cam follower 10.11, which is in pressure contact with the cam follower 16, can be moved up and down.

In addition, the cam follower To, 11 is provided in a positional relationship such that it maintains contact with the disc cam 12, 13 even when the reeling fishing arm 8°9 moves horizontally to advance and retreat to the packaging position. .

Further, the upper disc cam 12 slides in the vertical direction along the support shaft 14 because the distance between the winding needles 4 and 5 at the starting position must be adjusted depending on the thickness of the coins to be wrapped. Then, the starting position is determined.

The vertical movement of the disc cam 12 is performed by a link 17 that swings in conjunction with, for example, a denomination value or a denomination button.

Therefore, on the cam surface 15 of the upper disc cam 12,
A recess 18 is formed to allow the winding needle 4 to move further down beyond the stroke until the winding needle 4 comes into contact with the top surface of the stacked coins.

This recess 18 is where the winding needle 4 finally rolls up the wrapping paper.
The cam surface 15 is formed on the trailing side of the cam surface 15, which is formed so as to be in contact with both end surfaces of the coin.

On the other hand, a limit switch 19 that moves up and down integrally following the vertical movement of the disc cam 12 faces below the arm 8 for reel fishing that supports the reel hook 4. The cam follower 10 is located in the recess 18 of the cam surface 15 of the disc cam 12.
When the reel fishing arm 8 descends beyond a predetermined stroke, it comes into contact with this switch 19 and turns on this switch 19.

This switch 19 is turned on to stop a motor (not shown) that is the prime mover for various operations for wrapping coins, to issue a coin shortage alarm, or to switch the chute for wrapped coins. This works in such a way that the coin rolls with a shortage of coins are stored in a storage box that stores only the coin rolls with a coin shortage.

With the above-mentioned configuration, a predetermined number of coins can be transferred to the coin transfer section 1 without any problems.
The operation when the material is supplied between the packaging rollers 2, 2, 2 will be explained.

Depending on the type of coin, the link 17 swings and the upper cam plate 1
2 in place.

Thereafter, with the start of the wrapping operation, the support shaft 14 rotates, causing the disc cams 12, 13 to rotate.

While the cam follower 10.11 is in contact with the cam surface that determines the starting position of the disc cam 12.13, the winding arms 8 and 9 are moved horizontally by a support shaft (not shown) and moved to the packaging position. and stop.

At this time, the cam followers 10, 11 come into contact with the cam surfaces of the disc cams 12, 13 that move the rolling arms 8, 9 up and down, and as a result, the rolling arms 8, 9 move up and down via the cam followers 10, 11. to give the winding needles 4 and 5 a predetermined stroke for winding up the wrapping paper.

At this time, when the winding needles 4 and 5 touch both end surfaces of the stacked coins at the final stage of winding up the wrapping paper, the cam follower 10 is positioned above the recess 18 in the cam surface 15 of the disc cam 12. but,
Since the number of stacked coins is a predetermined number, cam follower 1
0 does not fit into the recess 18, the winding needles 4 and 5 perform a predetermined operation for winding up the wrapping paper.

Thereafter, the cam follower 10.11 is brought into contact with the cam surface of the disc cam 12, 13 which causes the winding needles 4, 5 to retreat and is moved to the starting position.

In this state, the winding arms 8 and 9 are returned to the horizontal direction and the winding needles 4.5 are withdrawn to the outside of the packaging position.

Next, when the number of coins is insufficient, the cam follower 10 fits into the recess 18 of the cam surface 15 of the cam plate 12 during the winding operation of the wrapping paper by the winding needles 4 and 5 described above. ,
The winding arm 8 descends and comes into contact with the switch 19 located below the arm 8, turning the switch 19 on.

This makes it known that there is a coin shortage.

The above-described predetermined operation is performed, and the coin rolls with insufficient coins are not mixed with normal coin rolls.

FIG. 2 shows another embodiment of the device for detecting a shortage of coins in a coin packaging machine according to the present invention.

In this embodiment, the upper reel fishing arm 21 having the reel hook 4 swings about the first fulcrum 22 and rotates around the first fulcrum 22.
It is configured to be able to move up and down along a support shaft 24 by a first lever 23 which is rotatable with respect to 2.

A pair of links 25.2 are provided at the other end of the first lever 23.
A winding needle position setting shaft 27 is pivotally mounted via 6.
Link 26 is fixed to this shaft 27.

Therefore, due to the rotation of this shaft 27, the first lever 23 is
It rotates around a fulcrum 22 to move the winding arm 21 up and down.

On the other hand, a second lever 28 is pivotally attached to the first fulcrum 22, a cam follower 29 is provided protruding from one end of the second lever 28, and the other end is used for setting the winding needle position. It is rotatably attached to the shaft 2T.

The cam follower 29 is provided with a disc cam 30 that gives the winding needle 4 a predetermined stroke for winding the wrapping paper.

A cam surface 31 is formed on this disk cam 30, and the rotation of the disk cam 30 causes the cam follower 29 to move up and down along the cam surface 31 of the cam plate 30, thereby causing the second lever 2
3 swings around an end pivotally connected to the winding needle position setting shaft 27.

At this time, the first fulcrum 22 to which the first lever 23 and the second lever 28 are pivoted becomes movable, while the pivot point 32 of the first lever 23 and the link 25 becomes the second fulcrum. The second lever 23 is centered around the second fulcrum 32.
It swings following the lever 28.

A recess 33 similar to that shown in the previous embodiment is formed in the cam surface 31 of the disk cam 30, and when the number of coins is insufficient, the cam follower
9 fits into this recess 33, and the lever 23 descends beyond a predetermined stroke and comes into contact with a limit switch 34 disposed below this lever 23.

The action of this switch 34 is similar to the action of switch 19 in the previous embodiment.

Next, the effect will be explained.

First, rotate the winding needle position setting shaft 27 to
is swung about the first support 22, the winding arm 21 is maintained at a predetermined position suitable for the type of stacked coins, and the winding needle 4 is positioned at the starting position.

Thereafter, the disc cam 30 is rotated to give a predetermined stroke to the cam follower 29 that is in sliding contact with the cam surface 31.

Then, the second lever 28 having the cam follower 29 swings around the end pivoted to the winding needle position setting shaft 27, and following this, the second lever 23 swings around the second fulcrum 32. oscillate.

As a result, the winding needle arm 21 moves along the support shaft 24, and the winding needle 4 performs a predetermined operation for winding up the wrapping paper.

Note that the lower winding needle (not shown) is also performing a predetermined winding operation at the same time.

By the way, when there are a predetermined number of coins, even if the cam follower 29 is located above the recess 33 of the cam surface 31 of the disc cam 30, the winding needle 4 is in contact with the end surface of the coin. , the predetermined winding operation is performed without the cam follower 29 fitting into the recess 33.

On the other hand, if the number of coins is insufficient, Cam Follower 2
9 fits into the recess 33 of the cam surface 31, and the lever 23 descends beyond a predetermined stroke and comes into contact with the switch 34, causing the switch 34 to perform the above-described predetermined action.

In the case of this embodiment, the disc cam 30 can be kept at the fixed position even though the starting position of the winding needle 4 is changed, and the second lever 28 and the fulcrum 22 are not connected to the winding needle 4.
A switch 34 is provided at a fixed position to detect excessive movement of the winding needle 4 so that it maintains a constant rocking position despite changes in the starting position of the winding needle 4, and a lever whose position changes when the starting position of the winding needle 4 is changed. 23, the switch cannot be operated in the vicinity of the fulcrum 22, which always moves in a constant manner, and even when the lever 23 operates the switch 34 as in this embodiment, the switch 34 is in a fixed position. It has the advantage of being

Further, in this embodiment, the third lever 23 is the link 25
, 26, but the initial positioning of the first lever 23 may be done using a denomination knob or a denomination button. However, this may be done by selecting the denomination and number of coins to be shuffled.

Furthermore, it may be linked to a wrapping paper width detection system, or in a coin wrapping machine that loads wrapping paper for each denomination and selectively uses the wrapping paper, it can be operated using a wrapping paper selection knob or button. You can do it like this.

Furthermore, in both of the embodiments described above, switch 19.
Although it has been described that the levers 8 and 23 are in direct contact with the switch actuating lever 34, the levers 8 and 23 may be in contact with a switch operating lever and the switch is turned on by the action of this lever.

As described above, the coin wrapping machine lack detection device according to the present invention has a winding needle whose starting position in the vertical direction is changed according to the height of the stacked coins. A concavity is formed in the cam surface of the cam that gives the stroke, in which the winding needle moves toward the stacked coins for a predetermined stroke or more, and the winding needle is interposed between the cam and the winding needle and is interlocked with the cam surface of the cam. A switch is disposed near the lever that raises and lowers the winding needle, and when the lever moves excessively due to the recess in the cam, this switch is activated, making it possible to handle coins with a shortage of coins. It is possible to easily detect a shortage in the number of stacked coins by simple operations, and the detection is reliable, which is an excellent effect.

Further, the positioning of the switch when assembling the machine can be done based on the recess of the cam, and there is no need for actual alignment as in the conventional case, and the assembly is easy.
