Abstract

PURPOSE:To perform effective automatic vending operation with simple structure by guiding an article, guided from a guide member to a flank by the rotation of a cam member, to an article extrusion part, and extruding the article to an article takeout opening by the continuous rotation of the cam member. CONSTITUTION:When coins are thrown in a coil slot and a button for chewing gum is pressed, a current which rotates a driven gear 29 to the position where a switch lever pressure cam 31 and a roller 61 abut on each other flows to a motor 35. When the switch lever pressing cam 31 and roller 61 abut on each other, a switch 37 is turned on and the current flows to the motor 35. Consequently, the driven gear 29 further rotates and the gum 21 approaches an article support base 51 gradually. When the driven gear 29 furthermore rotates, the gum 21 moves onto the support base 51. When the gear 29 further rotates, an article extrusion part 55 extrudes the gum 21. This extruded gum 21 is guided to the article takeout opening. Further, when the gear 29 further rotates and the switch lever pressure cam 31 and rollers 61 leave each other, the motor 35 stops.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is provided in a vending machine, and by operating a button for a desired article, the article in the vending machine is carried out to the article outlet. This article relates to an article delivery mechanism.

[Prior Art] FIG. 6 is a schematic diagram of an article delivery mechanism provided in a conventional vending machine. On the article support stand 4 is a magazine 3a.
, 3b are located. The gum 1 is housed in the magazines 3a and 3b. The gum 1 stored in the magazine 3a and the gum 1 stored in the magazine 3b are the same type of gum. A slide angle 5 is located between the magazines 3a, 3b and the article support stand 4.

One end of the slide angle 5 and the cam 9 are connected to the link 7
connected by. The cam 9 is rotationally driven by a motor (not shown). A switch 11 is arranged near the cam 9.

When the switch 11 is turned on, electricity flows to the motor that rotates the cam 9, and when it is turned off, electricity is stopped. When the protrusion 13 of the cam 9 and the roller 12 come into contact, the switch 1
1 becomes ON. The recess 14 of the cam 9 and the roller 12 are
They are in a position where they do not touch each other. Therefore, when the recess 14 comes near the roller 12, the switch 11 is turned off.

The operation of a conventional article delivery mechanism will be briefly explained.

First, put money into the coin slot and press the gum 1 button. As a result, electricity flows to the motor that rotates the cam 9. The amount of electricity is the amount that rotates the cam 9 until the convex portion 13 and the roller 12 come into contact.

When the roller 12 and the convex portion 13 come into contact, the switch 11 is turned on, and the cam 9 further rotates. As a result, the slide angle 5 moves in the B direction. roller 12
When the cam 9 rotates to a position where it is no longer in contact with the convex portion 13, the slide angle 5 causes one of the gums 1 stored in the magazine 3b to drop downward. Since the roller 12 and the convex portion 13 are no longer in contact with each other, the slide angle 5 stops at this position. When the user inserts new money into the coin slot and presses the button on the gum 1, one of the pieces of gum 1 stored in the magazine 3a falls downward.

[Problems to be Solved by the Invention] Conventionally, the gum 1 was carried out by linearly moving the slide angle 5 back and forth. The reciprocating linear movement of the slide angle 5 was performed by the rotational movement of a motor.

Therefore, the link 7 is required, and the article delivery mechanism becomes larger.

In addition, the connection between the slide angle 5 and the link 7 or
If the connection between the link 7 and the cam 9 becomes disconnected for some reason, the rotation of the motor will no longer be transmitted to the slide angle 5, making it impossible to carry out the gum 1.

This invention was made to solve these conventional problems. An object of the present invention is to provide an article discharging mechanism that does not use links.

[Means for solving the problem] The article delivery mechanism of the vending machine carries out the articles inside the vending machine.
Carry it out to the goods removal port. The article delivery mechanism for a vending machine according to the present invention includes a base, a cam member, a drive source, a guide member, and an article extrusion section. The cam member is rotatably attached to the base.

The drive source is attached to the base and rotates the cam member.

A guide member is attached to the base and guides the article to the side of the cam member material. The article pushing part is a part of the side surface of the cam member, and pushes out the article toward the article outlet.

In the article dispensing mechanism of the vending machine according to the present invention, when the cam member rotates, the article guided to the side from the guide member is guided to the article pushing part, and when the cam member further rotates, the article is guided to the side from the guide member.
The article is pushed out toward the article outlet.

[Function] In this invention, the cam member directly carries out the article. Therefore, the size can be reduced compared to the case where links are used. Further, the connection between the link and the cam or the connection between the link and the slide angle is disconnected, and the rotational force of the motor is no longer transmitted to the slide angle, so that it is no longer impossible to carry out the article.
