FIG. 1 is a brief sectional view for illustrating an opening and closing structure of a bill input inlet of a conventional automatic vending machine, and
FIG. 2 is a brief sectional view including a detailed partial view for illustrating an opening and closing structure of a bill input inlet of an automatic vending machine in accordance with the present invention.
Detailed Description of the Invention
An embodiment of the present invention is described in detail with reference to the accompanying drawings. In FIG. 2, like reference numerals and symbols are used for designation of like or equivalent parts or portions in FIG. 1 for simplicity of illustration and explanation, and redundant references will be omitted.
The opening and closing structure of a bill input inlet of an automatic canned product vending machine in accordance with the present invention, comprises a bill input inlet(11) disposed at a predetermined position of a front cabinet(10), a bill discriminating apparatus(30) embedded inside of the front cabinet(10) at a same height level to the bill input inlet(11) for discriminating the authenticity of a bill induced through the bill input inlet(11) and for storing the bill and a movable bill input inlet door(200) hinged at the upper side of the bill input inlet(11) for opening and closing the bill input inlet(11), wherein the bill input inlet is constructed of an opening and closing structure where, after a bill input inlet door is lifted up to a door inducing member, the bill input inlet door is hitched and momentarily stopped by a stopping pin of door control means, and is closed by its falling weight as the stopping pin is raised in a certain time duration, thereby making it easy to conveniently insert the bill.
The door inducing member(100) comprises a door inducing inlet(110) formed in a pipe correspondingly to the curve of the bill input inlet door(200) being connected open to the front with the ends thereof fixed at the upper sides of the bill input inlet(11) and the bill discriminating apparatus(30) and a stopping pin moving hole(120) to enable the stopping pin(342) to penetrate through.
The bill input inlet door(200) comprises a plastic door plate(220) with a stopping pin accommodating portion(210) formed for causing the stopping pin(342) to be lowered and compressed under a predetermined pressure.
The door control means(300) comprises a micro-switch(310) installed behind the door input inlet(110) to be turned on as the bill input inlet door(200) is pushed in and compressed in more than a predetermined pressure, a programmable logic controller (PLC) board to get the ON signal of the micro-switch(310) and to determine a waiting time duration, rotating direction and frequency of a motor(330), a motor(330) to be rotated by the signal from the PLC board(320), a pinion(332) installed at one end of a rotating shaft(331) of the motor(330) and a door control member(340) having a vertically movable prominence part(341) to be met with the pinion(332) and a stopping pin(342) to be moved through the stopping pin moving hole(120) as it is lowered and to compress the stopping pin accommodating portion(210) in a predetermined pressure.
Next, operational effect of the present invention is described in detail. In order to get the bill(a) inserted into the bill inducing inlet(32) of the bill discriminating apparatus(30), the bill input inlet door(200) is lifted up open to the end, the rear part of the bill input inlet door(200) turns on the micro-switch(310) of the door control means(300) and the ON signal of the micro-switch(310) is sent to the PLC board(320).
The PLC board(320) sends a signal input with a waiting time duration, and rotation direction and frequency to the motor(330) which is rotated by the signal to get the door control member(340), whereby an end of the stopping pin(342) puts a predetermined pressure on the stopping accommodating portion(210)of the bill input inlet door(200).
Therefore, the door control member(340) is stopped for a time according to the data input at the PLC board(320). At this time, the bill (a) is inserted through the bill inducing inlet(32).
The door input inlet door(200) is lifted up open to the door inducing inlet(110) of the door inducing member(100) and released, the door input inlet door(200) is hitched and stopped by the stopping pin(342) of the door control means(300) for a predetermined time duration, and then the bill input inlet door(200) falls down by its weight as stopping pin(342) is raised.
There is an advantage of the present invention in that a bill input inlet of an automatic vending machine is constructed with an opening and closing structure where, after the bill input inlet door is pushed up to the door inducing member(100), a bill input inlet door is hitched and stopped by the stopping pin(342) for a predetermined time duration and then the door falls down by its weight as the stopping pin(342) is raised, thereby getting a bill conveniently inserted only by using one hand of a customer.
Even if the embodiment of the present invention is described here, the actual scope of the present invention is not limited in the presented embodiment. It is believed evident that many variations be made by those skilled in the art without departing from the spirit and scope of this invention.
