Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a coin dummy iron piece removal device in a coin sorting device.

(Prior art and its problems) As a method for checking the material of coins in a coin sorting device, the coin is rolled on a ramp across a magnetic field by a permanent magnet to give the coin a magnetic braking effect. It is common practice to select genuine coins by utilizing the phenomenon that the function of coins differs depending on the material of the coin, and in recent years, powerful permanent magnets have been used to improve the accuracy of such material checks.

However, when such a strong permanent magnet is used for the purpose of checking the material of a coin, a coin-fake iron piece removing device using a relatively weak permanent magnet is installed before the coin passes within the magnetic field of the permanent magnet for checking the material. This solves the problem of difficult removal caused by the coin pseudo iron pieces being strongly attracted to the material checking permanent magnet.

In the conventional coin pseudo iron piece removal device, a permanent magnet piece is attached to one side of two parallel coin passage side plates made of aluminum, zinc alloy, or synthetic resin material, and is made to look into the coin passage. The coin dummy iron pieces passing along the coin path are attracted and held by the permanent magnet pieces, and the coin dummy iron pieces thus attracted and held by the permanent magnet pieces on one side plate are removed from the coin passage. Therefore, a rejection plate is provided on the other coin passage side plate, and this rejection plate is placed across the coin passage on the side of one coin passage side plate, and by operating the return lever of the coin sorting device, the other side plate is removed from the one side plate. When the coin is rotated around the hinge device and opened, the removal plate separates the coin from the permanent magnet piece and causes it to fall into the return chute below.

However, in order to use the removal plate to separate the piece of iron that is attracted to the permanent magnet piece, a considerable force is applied to the removal plate even if the permanent magnet has a weak magnetic force, which not only increases the operating force of the return lever but also removes the piece of iron. There is a problem that the plate needs to have the strength to withstand the peeling force.
This becomes a problem particularly when the coin passage side plate is constructed from a synthetic resin material in order to reduce the weight and material cost of the coin sorting device.

In addition, as a prior art, the specification of Utility Model Application No. 55-190598 (Utility Model Application No. 57-114465) discloses that a magnet piece is provided on the outside of a fixed side plate on one side of the coin passage, and a return lever can be operated to remove coins from the coin passage. A structure is disclosed in which the magnet piece is attached to the return lever mechanism so that when the movable side plate is rotated about the hinge to open the coin passage, the magnet piece is moved away from the fixed side plate in a substantially perpendicular direction.

However, the coin passage side plate is generally made of non-magnetic material such as aluminum, zinc alloy, or synthetic resin material and has a considerable thickness, and the iron-based pseudo coins or iron pieces inserted from the coin slot have a considerable speed. Since the coins pass through the coin passageway, in order to attract such pieces of iron with the magnets installed on the outside of the passage side plate, it is necessary to use a strong permanent magnet for the sole purpose of removing the pieces of iron, which is costly. In addition, there is a problem in that a large operating force is required to separate the magnets that attract the iron pieces in the same axial direction.

The present invention attempts to solve the problems of the prior art mentioned above.

(Means for solving the problem) Therefore, according to the present invention, a ferromagnetic piece 5 such as an iron piece is attached to the coin passage side plate 1 made of a non-magnetic material such as a synthetic resin so as to pass through the coin passage 3. Piece 5
The permanent magnet piece 8 is in contact with the outer end of the ferromagnetic piece 5, and the coin pseudo iron piece is aligned on the axis of the ferromagnetic piece from the coin pseudo iron piece adsorption/holding position parallel to the outer surface of the side plate 1. It is characterized in that it is attached to a return lever mechanism so as to be moved outside the coin path in a direction perpendicular to the axis along the coin path.

(Function) According to the present invention, when the permanent magnet piece 8 is in the coin pseudo iron piece adsorption/holding position, the ferromagnetic piece 5 attached to the coin passage side plate 1 is magnetized and attracts the coin pseudo iron piece. Therefore, permanent magnet pieces 8 having normal magnetic force can be used.

When removing the iron piece held in the coin passage by the permanent magnet piece 8, it is extremely small compared to the case where the end face of the permanent magnet piece 8 is shifted parallel to the outer end face of the ferromagnetic piece 5 and separated at a right angle. The permanent magnet piece 8 can be moved and separated from the ferromagnetic piece 5 with a strong force, and the force required to operate the return lever can be reduced.

(Embodiment) The drawing shows one embodiment of the present invention, and in the drawing, 1 and 2 are synthetic resin coin passage side plates provided in parallel and spaced apart, one side plate 1 being a fixed side plate, and the other side plate being a fixed side plate. 2 is the movable side plate, and one side is the fixed side plate 1.
When the return lever (not shown) is operated, the side plates 1 and 2 rotate around the hinge connection.
The coin passage 3 between them is configured to be openable.

A ferromagnetic piece 5 such as a piece of iron is inserted through the through hole 4 formed in the fixed side plate 1, and the inner end 5a thereof is exposed to the coin passage 3. The pivoting lever 6 is rotatably attached to its boss portion 6a by a pivot pin 7, and the pivoting lever 6
A permanent magnet piece 8 is fixedly attached to the outer end of the ferromagnetic piece 5 on the fixed side plate 1 in a position aligned on the axis of the ferromagnetic piece 5, and a spring 9 is attached to the boss portion 6a of the swing lever 6. When installed, one end 9a of this spring is engaged with the swinging lever 6, the other end 9b is engaged with the pin 10 on the fixed side plate 1, and the permanent magnet piece 8 on the swinging lever 6 is connected to the ferromagnetic piece on the fixed side plate 1. The upper end of a push-up rod 11 operated by a return lever is engaged with one end 6b of the swing lever 6 so that the swing lever 6 is always held at a position overlapping the lever 5 by a spring force. Reference numeral 12 designates a pin for opening the movable side plate fixed to the other end 6c of the swing lever 6, which penetrates through an arcuate slot 13 provided in the fixed side plate 1 and projects its hemispherical tip 12a into the movable side plate 2. As is known to those skilled in the art, the movable side plate 2 is moved by engaging the provided ramp 14 and moving the tip 12a of the pin 12 along the ramp 14 when the swing lever 6 is rotated. It is configured to be open.

With the above-described configuration, the ferromagnetic piece 5 on the fixed side plate 1 is magnetized by the permanent magnet 8 on the swinging lever 6 located overlapping therewith, and therefore, the ferromagnetic piece 5 on the fixed side plate 1 is magnetized by the permanent magnet 8 on the swinging lever 6 located overlapping the ferromagnetic piece 5. It is possible to adsorb and hold the coin-like piece of iron that you are about to use.

The coin pseudo-iron piece thus attracted and held by the permanent magnet 8 via the ferromagnetic piece 5 is pushed up vertically by the push rod 11 by operating the return lever, and the swinging lever 6 is moved as shown by the imaginary line in FIG. By being rotated as shown, the permanent magnet piece 8 moves along the outer surface of the fixed side plate 1 from the position where it overlaps with the ferromagnetic piece 5, thereby removing the magnetic effect from the ferromagnetic piece 5. The coin pseudo-iron piece, which was held by the permanent magnet piece 8 via the ferromagnetic piece 5, falls due to its own weight and is removed from the coin passage 3.

(Effect of the invention) According to the invention, the magnetic adsorption effect of the permanent magnet piece is applied to the iron piece passing into the coin passage through the ferromagnetic piece that is attached to the side plate of the coin passage. Permanent magnets can be used,
By moving the permanent magnet parallel to the coin path side plate, the operating force required to move the permanent magnet piece to the iron piece removal position can be reduced, which can simplify the structure of the removal mechanism and reduce manufacturing costs. Effects can be obtained.
