Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of detecting an excess or deficiency in the number of wrapped coins in a coin packaging machine, and also prevents normal packaging by eliminating or preventing the release of excess or insufficiently packaged coins. The purpose is to make it possible to distinguish them from coins.

In conventional coin packaging machines, coins are counted one by one and a predetermined number of coins are stacked in a stacking tube, but up to this point, it has been devised that the number of coins stacked is strictly checked by various means. ing. If the number of coins is incorrect, the coins are rejected without being transferred to the wrapping section, but once they are determined to be normal and are transferred to the wrapping section, the coins are wrapped without checking. However, even if the exact number of coins is in the stacking cylinder, one or two coins may fall off due to machine vibration or unstable coin support while moving the coins between the three packaging rollers in the packaging section. In this case, the packaging operation is carried out as usual, so there is a drawback that it is impossible to detect fraudulent coins after packaging. The present invention is capable of detecting not only the shortage of coins actually wrapped in wrapping paper but also the rare case of a large number of coins being wrapped in the packaging section, and detecting an abnormality in the number of coins wrapped. If a coin is detected, it is distinguished from a normally packaged coin to prevent cash accidents from occurring.

Next, the present invention will be explained in detail based on the drawings shown as embodiments. Coins 1 are calculated in a certain number and transferred from a stacking tube (not shown) to the packaging area supported by a support rod 2, rotated while being held between three packaging rollers (not shown), and the outer periphery of the coins is rotated. Wrapping paper 3 is wrapped around.

Reference numerals 4 and 4' denote cotton padding claws, which are attached to arms 5 and 5', which are guided by a rod 6 and can be moved close to each other by a spring 7.

The upper arm 5 is connected to one end of a crimping lever 9 centered on a fulcrum shaft 8, and the other end of the lever 9 is in contact with a crimping cam 10. A position change lever 11 is further pivotally attached to the fulcrum shaft 8, one end of which touches a support 13 whose position can be changed up and down by a rod 12, and the other end touches a disk 14, which serves as the pivot point of the position change lever 11. becomes.

In addition, when the other end of the position conversion lever 11 is pivotally attached to the body, it is necessary to form a long hole in the length direction of the lever at the portion where the fulcrum shaft 8 is pivotally attached. A microswitch 15 is mounted on the support 13 so that its operating punch 16 can come into contact with the upper arm 5.

Reference numeral 17 denotes a shaft that moves on a denomination dial (not shown), which is one of the denomination setting means, and has a denomination setting cam 18, which is in contact with the fulcrum shaft 8 via a trochanter 19. ing.

This is a support arm that movably supports the fulcrum shaft 8 and is pivotally connected by a pin shaft 21, and the caulking cam 10 and the disc 14 are attached to a drive shaft 22. In packaging, as in the prior art, the arms 5 and 5' are positioned in accordance with the stacking height of the coins 1, which varies depending on the thickness of the coins, by means of a denomination setting cam 18 which rotates in accordance with the setting of a denomination dial.

Then, the accumulated coins 1 are supported on the support rods 2 and transferred to the wrapping section, and the wrapping paper 3 is wrapped around them. Since the position of the fulcrum shaft 8 is also changed by the denomination setting cam 18, the support body 13 is set to a position corresponding to the change by operating the position changing lever 11. In response to the rotation of the support cam 10, the support lever 9 operates around the fulcrum shaft 8, and the spring 7
With the accumulated force, both ends of the wrapping paper 3 are crimped by the crimping claws 4, 4', and the crimping operation is completed when the tip of the crimping claw 4 comes into contact with the top surface of the coin.

Therefore, if the number of accumulated coins 1 is insufficient at this time, the crimping pawl 4 will be further lowered.

Then, a part of the arm 5 comes into contact with the actuation point 16 of the microswitch 15, which has been previously positioned at an appropriate position via the fulcrum shaft 8 displaced by the denomination cam 18 and the position conversion lever 11, and the switch 15 is actuated. It will be done. Through this operation, a shortage of coins is detected and, for example, the coin wrapping machine is stopped or the wrapped coin ejecting chute 23 as shown in FIG.
The magnet 26 that closes the lid 25 of the drop opening 24 is energized, and the lid 25 is closed to distinguish the coin from a correctly packaged coin. Although not shown, the chute 23 may be made into a bifurcated shape, and a damper for switching the passage may be provided at the branching point so that both genuine and fraudulently wrapped coins can be sorted. In the above embodiment, the micro switch 1
Although it is an automatic type that changes the position of 5, there is a micro switch 1
5 is mounted on a manual support 13' as in the embodiment shown in FIG.
You may manually convert its position according to the following. This manual type allows the structure to be extremely simplified.
The above embodiment detects only when there is a shortage of accumulated coins (which is often the case), but in the embodiment shown in FIG.
It is possible to detect any cases of shortage.

That is, two microswitches 15 and 15' are provided whose positions can be changed and set depending on the denomination, and as shown in FIG. Arm 5 does not touch (Fig. 5 a)
At that time, the lid 25 shown in FIG. 3 is closed (always in the closed state), and if the number of sheets is correct, only one switch 15 is activated (see FIG. 5b) to open the lid 25.
is opened, and if there is still a shortage, both switches 15 and 15' are activated (see Fig. 5c). In this case, by wiring the magnet 26 so that the lid 25 is closed, it is easy to prevent an excess of wrapped coins. , the shortage can be detected and obtained. In this way, the present invention can quickly detect an abnormality in the number of coins actually wrapped in wrapping paper (insufficiency or excess or deficiency), and based on this detection, the work can be stopped or selected, so that it is not possible to determine excess or deficiency at first glance. To reliably distinguish difficult-to-wrappe coins, and to have a simple structure without any failure points.
