Vending machine with a vibration sensor
View Patent ↗When a coin(s) is inserted and an article selection button is further pressed, article carrying-out processing is started, and an article carrying-out device performs a carrying-out operation. An article is dropped and received in a receiving section by this carrying-out operation. When the article is received in the receiving section, the article collides with the receiving section, and vibrations are generated. The vibrations are detected by a vibration detection unit, and it is judged that the article is received in the receiving section. In the series of article carrying-out operations, when unexpected vibrations are applied to the receiving section after the article carrying-out processing is started, since a microcomputer excludes the vibrations, only vibrations at the time of receiving the article can be detected accurately.
1. A vending machine comprising:
an article carrying-out device which carries out an article;
a receiving section in which the article carried out from said article carrying-out device is received;
a vibration detection means which detects vibrations generated in said receiving section; and
a judgment means which judges that the article is received in said receiving section on the basis of the vibrations detected by said vibration detection means and excludes vibrations detected in a time slot, in which vibrations due to carrying-out of an article cannot be generated, after said article carrying-out device is started among vibrations detected by said vibration detection means.
2. A vending machine comprising:
an article carrying-out device which carries out an article;
a receiving section in which the article carried out from said article carrying-out device is received;
a vibration detection means which detects vibrations generated in said receiving section;
a judgment means which judges that the article is received in said receiving section on the basis of the vibrations detected by said vibration detection means; and
a control means which controls the article carrying-out operation of said article carrying-out device to be prohibited for a predetermined time when vibrations are detected at least once by said vibration detection means at the time of standby for carrying out the article.
3. A vending machine comprising:
an article carrying-out device which carries out an article;
a receiving section in which the article carried out from said article carrying-out device is received;
a vibration detection means which detects vibrations generated in said receiving section;
a judgment means which judges that the article is received in said receiving section on the basis of the vibrations detected by said vibration detection means and excludes vibrations detected in a time slot, in which vibrations due to carrying-out of an article cannot be generated, after said article carrying-out device is started among vibrations detected by said vibration detection means; and
a control means which controls the article carrying-out operation of said article carrying-out device to be prohibited for a predetermined time when vibrations are detected at least once by said vibration detection means at the time of standby for carrying out the article.
4. The vending machine according to claim 2 ,
wherein the vibrations detected by said vibration detection means are vibrations detected intermittently twice or more.
5. The vending machine according to claim 3 ,
wherein the vibrations detected by said vibration detection means are vibrations detected intermittently twice or more.
6. The vending machine according to claim 4 ,
wherein a time interval of the vibrations is a time interval shorter than a time in which the article carrying-out operation is completed.
7. The vending machine according to claim 5 ,
wherein a time interval of the vibrations is a time interval shorter than a time in which the article carrying-out operation is completed.
8. The vending machine according to claim 2 ,
wherein the predetermined time, in which the article carrying-out operation of said article carrying-out device is prohibited, is set substantially equal to or slightly longer than a time required for carrying out one article.
9. The vending machine according to claim 3 ,
wherein the predetermined time, in which the article carrying-out operation of said article carrying-out device is prohibited, is set substantially equal to or slightly longer than a time required for carrying out one article.
10. The vending machine according to claim 4 ,
wherein the predetermined time, in which the article carrying-out operation of said article carrying-out device is prohibited, is set substantially equal to or slightly longer than a time required for carrying out one article.
11. The vending machine according to claim 5 ,
wherein the predetermined time, in which the article carrying-out operation of said article carrying-out device is prohibited, is set substantially equal to or slightly longer than a time required for carrying out one article.
12. The vending machine according to claim 6 ,
wherein the predetermined time, in which the article carrying-out operation of said article carrying-out device is prohibited, is set substantially equal to or slightly longer than a time required for carrying out one article.
13. The vending machine according to claim 7 ,
wherein the predetermined time, in which the article carrying-out operation of said article carrying-out device is prohibited, is set substantially equal to or slightly longer than a time required for carrying out one article.
