Description

[Detailed description of the invention] Concerning vending machines that obtain products.

2. Description of the Related Art In currently used vending machines such as soft drink vending machines and automatic ticket vending machines, it is common to insert coins one by one into a slit-shaped slot. In addition to the disadvantage that it is difficult to insert coins, this also has the disadvantage that it takes an unexpected amount of time and is inefficient when a large number of coins are inserted.

An object of the present invention is to provide a vending machine that can eliminate this drawback and that allows a plurality of coins to be inserted at the same time.

According to the present invention, there is provided an input slot large enough to accept a plurality of coins at the same time, and a passage inclined downwardly behind the input opening, and in the middle of this passage, Means are provided which act to pass the coins one by one. This means has a part projected from one side wall of the passage, and maintains a gap between the circumferential surface of the passage and the other side wall, which is slightly larger than the thickness of one coin, but smaller than the thickness of two coins. , in the form of a friction roller rotating in a direction opposite to the direction of movement of the coin.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 shows the front panel of an automatic ticket vending machine, and it is the coin slot 2 that is relevant to the present invention.

Therefore, other parts will not be discussed at all. As can be seen from the figure, the coin slot 2 has a rectangular opening, unlike a conventional slit, so that a plurality of coins can be inserted at once.

Referring to Figures 2 and 3, a passage 3 is provided behind the rectangular coin slot 2 provided on the front panel, and this passage is also wide enough to receive a plurality of coins 4. have. The passage 3 is tilted downward and communicates with a well-known coin validating section (not shown), and includes a top wall 5, a bottom wall 6, a side wall 7.
Consists of 8.

(3) A friction roller 9 is provided so as to partially protrude from one side wall 7, and this roller is mounted on an axis 0 perpendicular to the bottom wall 6 of the passage 3. The friction roller 9 is positioned so as to maintain a distance between its circumferential surface and the surface of the other side wall 8, which is slightly larger than the thickness of 401 coins but smaller than the thickness of two coins 4. .

The shaft 10 is driven by a motor 12 through a belt 13.
It acts to push back the coins rolling down the passage 3, except for one coin closest to the side wall 8. When one coin passes between the side wall 8 and the friction roller 9, the next coin moves to the passing position despite the return action of the friction roller 9, and one coin at a time, the coins are moved to the friction roller 9. pass through. The passing coins are sent one by one toward a coin validation section (not shown) by a feeding roller 14 at predetermined time intervals. This feed roller 1
4 is for sending coins at intervals according to the detection ability of the coin verification section (4), which is a well-known function in this field, so the spring 15 is used as shown in FIG. 3.
A feed roller 14 is rotatably mounted on a pivot arm 16 which is pushed toward the side wall 8 of the passage 3, and the shaft 17 of this roller is in frictional contact with the running part of the belt 13 of the motor 12. The explanation will be limited to that it is connected by a pulley 18 and a belt 19.

The passage 3 has a friction roller 9 as shown in FIGS. 41 and 4B.
It is advantageous for the non-projecting side wall 9 of the machine to be inclined with respect to the vertical plane passing through the machine.

In this case, since the inserted coins roll on the bottom wall 6 along the side wall 8, each coin can more reliably pass between the side wall 8 and the friction roller 9 one by one. Therefore, even if coins are inserted one by one as in the conventional case, the coins can reliably reach the feed roller 14 without being affected by the friction roller 9. Furthermore, since the input port 2 is large, it is easy for garbage to enter.
In order to eliminate this, the side wall 8 without the friction roller 9 is pivoted at the top (5) edge 8A so that it can rotate in the direction away from the friction roller 9, and the automatic removal mechanism 2 is attached to this side wall 8.
It is preferable to connect 0i.

The automatic evacuation mechanism 20 includes a solenoid 22 which, when energized, operates to retract its rod 21, which rod 21 is attached to the side wall 8 via a link 23.

A tension spring 24 is mounted on the side wall 8, opposite the solenoid 22 and acting in a direction opposite to the retraction direction of the rod 21.

As shown in FIG. 2.3, the solenoid 22 is connected to a detection means, such as a phototube device 25, which is installed upstream of the friction roller 9 to detect coins in the passage 3. When the solenoid 22 remains for a predetermined period of time, the solenoid 22 is actuated to retract the rod 21 against the force of the spring 24, rotating the side wall 8 and opening the passage 3. If the coin was not moved due to the dirt 26 being clogged, the dirt 26 is now removed. When a predetermined period of time has elapsed or some other action is taken, the solenoid 22 is deenergized and the rod 21 is pulled under the force of the spring 24, causing the side wall 8 to return and close the passage (6). .

The electrical circuitry of an automatic exclusion mechanism that operates in this manner will be obvious to those skilled in the art and will not be described here.
