Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coin guiding device for a vending machine.

[0002]

[Prior art]

 For example, a conventional coin guiding device for a vending machine is described in Japanese Utility Model Laid-Open No. 54-90198.

Next, description will be made with reference to FIGS. 4, 5, and 6. 1 is a main body. Reference numeral 2 is a coin inlet provided in the main body 1. 3 is a coin guide attached to the main body. The coin guide tool 3 has a guide surface lower end 3a that is inclined toward the coin inlet at the lower part thereof, and a pair of curved guide surfaces 3b that are curved toward the guide surface lower end on both sides of the guide surface lower end 3a. 4 is a downward discharge port at the boundary between the lower end 3a of the guide surface and the coin inlet.

The operation of the coin guiding device of the vending machine configured as described above will be described below.

When purchasing a content product at a vending machine, when a coin is placed on the coin guiding tool 3, the coin slides down the guiding surface 3b, and when reaching the lower end 3a of the guiding surface, the coin rolls over the discharging opening. Cross over 4 and enter coin entrance 2. When it rains, rainwater flows out from the outlet 4 and does not enter the coin inlet 2.

[0006]

[Problems to be solved by the device]

 However, with the above-mentioned conventional structure, when inserting coins one by one, there is no problem because the coins will enter the coin inlet 2 simply by placing them on the coin guide 3, but there is no problem. When the coin guiding tool 3 is placed, there is a problem that it may be jammed between the opposing guiding surfaces 3b.

In view of the above problems, the present invention provides a coin guiding device for a vending machine which automatically returns coins when a plurality of coins are jammed between the guiding surfaces.

[0008]

[Means for Solving the Problems]

 In order to solve the conventional problems, a coin guiding device of a vending machine according to the present invention is provided with a coin inlet provided in a main body, a coin slot formed in front of the coin inlet, and an inside of the coin slot. The fixed guide surface formed, the movable guide surface pivotally supported at a position facing the fixed guide surface, the lower end of the movable guide surface formed below the movable guide surface, the fixed guide surface and the movable guide surface. Drive for rotating the movable guiding surface by operating in conjunction with the detection holes formed on both sides of the surface, the detection sensors attached on both sides of the detection hole, and the electrical signals from the detection sensors. It is provided with a device, a discharge chute provided at the bottom of the coin slot, and a refund port formed in the main body.

[0009]

[Action]

 The present invention has the above-mentioned configuration and automatically detects when a plurality of coins are jammed between the fixed guide surface and the movable guide surface and returns the coins.

[0010]

【Example】

 A coin guiding device for a vending machine according to an embodiment of the present invention will be described below with reference to the drawings.

1, 2, and 3 show a coin guiding device of a vending machine according to an embodiment of the present invention, those having the same structure as the conventional example are designated by the same reference numerals. Is omitted.

In the figure, reference numeral 10 is a coin slot. Reference numeral 11 is a fixed guide surface. Reference numeral 12 is a movable guide surface pivotally supported by a support shaft 13. Reference numeral 12a denotes a lower end of the movable guide surface which is formed at the lower end of the movable guide surface 12 and has a constant width that is inclined toward the coin inlet 2. Reference numeral 14 is a detection hole provided on both the fixed guide surface 11 and the movable guide surface 12. Reference numeral 15 is a pair of detection sensors located on an extension of the detection hole 14. Reference numeral 16 is a drive device that rotates and returns the movable guiding surface 12 when an electric signal from the detection sensor 14 is received for a certain period of time or longer. The above-mentioned certain period of time is a period of time during which the drive unit 16 does not operate with an electric signal from the detection sensor 15 when a normal coin is inserted. Reference numeral 17 is a discharge shoe located below the fixed guide surface 11 and the movable guide surface 12. Reference numeral 18 is a refund port connected to the discharge chute.

The operation of the coin guiding device of the vending machine configured as described above will be described below with reference to FIGS. 1, 2, and 3.

When purchasing a merchandise item at a vending machine, when a coin is placed on the coin insertion table 10, the coin slides down on the fixed guide surface 11 or the movable guide surface 12 and the lower end of the movable guide surface. 12a falls and rolls on the lower end 12a of the movable guide surface. In that case, the coin temporarily blocks the detection hole 14, but the drive device 16 does not operate, that is, the movable guide surface 12 does not rotate, so that the coin is Enter the coin entrance 2. However, when a plurality of coins are placed on the loading table 10 and are stuck between the fixed guide surface 11 and the movable guide surface 12, the coins block the detection hole 14 for a certain period of time or longer. The drive device 16 is actuated by the signal from the detection sensor 15 and the movable guide surface 12 is rotated, and the coin drops onto the discharge chute 17 and slides down to reach the refund port 18.

[0015]

[Effect of device]

 As described above, the present invention is capable of automatically returning coins to the refund slot when a plurality of coins are jammed on the coin input table, making coin insertion easy as in the conventional example. It eliminates the drawback of coins clogged up and provides an easy-to-use vending machine.
