Description

[Detailed description of the invention] This invention relates to the improvement of a vending machine that cooks and sells products using a heating device such as a microwave oven. Its main purpose is to reliably guide the product when the door is opened and to reduce the impact when the door is closed.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, 1 is the vending machine body with a heating device, and there is a door 2 on the front.
is installed so that it can be opened and closed.

The door 2 is equipped with product selection buttons 3, 3', etc., a coin slot 4, a change takeout port 5, a product takeout port 6, and a small door 7 for opening and closing the product takeout port 6. There is.

Reference numeral 8 denotes a guide chute for guiding the product from a product storage chamber (not shown) formed in the upper part of the main body 1, and when the product falls into the opening 9, it moves to the right as shown in FIG. A chute door 10 is provided which opens by opening.

Reference numeral 11 denotes a heating chamber formed in the lower part of the main body 1 and equipped with a heating device 12 such as a microwave oven, and a product guide door 13 that can be opened and closed and whose lower end is pivoted at the rear is attached, and the products are placed in the storage chamber. The product is guided into the heating chamber 11 through the guide chute 8 and the product guide door 13.

Further, the front of the heating chamber 11 serves as the product outlet 6, and a small door 7 is provided.

Reference numeral 14 denotes an opening/closing device for opening and closing the product guide door 13 at an acute angle at the rear end of the heating chamber 11. This opening/closing device 14 is constructed as follows.

Reference numeral 15 denotes a drive motor which rotates counterclockwise when the product is dropped.A shaft 15' is positioned above the rotating shaft support of the product guide door 13, and a circular cam plate 16 and an operating arm 17 are attached to this shaft 15'. Each is fixed.

The cam plate 16 is provided with a closing groove 18 and an opening groove 19 on its circular outer periphery.

Then, an open/close end switch 2, which will be described later, is placed in the open end groove 19.
When 0 is located, the product guide door 13 is in the maximum open state.

These grooves 18 and 19 are provided at positions where the circular cam plate 16 is offset, for example, at 120° and 240°, and the arcuate portion with a small angle is used as the opening portion A, and the arcuate portion with a large angle is used as the opening portion A. They are provided in the closing operation section B, respectively.

20 is the groove 18, 1 on the circular outer periphery of this cam plate 16.
9, both arcuate parts A, B, both grooves 18, 19
This is an opening/closing end switch equipped with an actuator 21 that slides on the top.

On the other hand, the operating arm 17 has a pin 24 at its tip that slides in a long hole 23 of a guide plate 22 provided on one side of the vertical wall of the product guide door 13.

Then, as the drive motor 15 rotates, the product guide door 13 slides in the elongated hole 23 from the shaft support side to the opposite shaft support side, thereby performing an opening operation.

To explain the operation of the opening/closing device 14 in the above structure, the drive motor 15 begins to rotate counterclockwise in response to the falling of the product.

At this time, the actuating arm 17 is positioned perpendicular to the door as shown in FIG.
located within.

As the motor 15 rotates, the cam plate 16 and the operating arm 17 rotate and push the pivot side of the door 13 and begin to open it, and the actuator 21 slides on the opening operation part A and falls into the opening end groove 19 and closes the door. 13 is completed.

At this time, the product guide door 13 stops in the maximum open state.

After that, the product is transferred from the storage room to the guide chute 8 and the chute door 1.
0. When the product is guided through the product guide door 13 into the heating chamber 11, this is detected by a detection switch (not shown), the drive motor 15 rotates again, and a closing operation is performed in the same manner as the opening operation described above. I repeat this.

Therefore, the opening operation of the guide door 13 utilizes the 120° portion of the opening portion A, and the closing operation utilizes the 240° portion of the closing portion B.
Since minutes are used, the closing operation time of the guide door 13 from the open position in the maximum open state to the closed position is longer than the opening operation time.

As a result, when receiving the product into the heating chamber 11, the guide door 13
The guide door 1 can be opened quickly to guide the guide door reliably and in a short time.
3 can be alleviated, and movement of the product within the heating chamber 11 caused by this impact can be prevented.

Furthermore, even if the closing operation of the guide door 13 starts with the product placed on the guide door 13, the product will be guided slowly into the heating chamber 11 by the guide door 13, so the product will not bounce off the product guide door. Therefore, a large impact is not applied to the product when it is stored in the heating chamber 11, and deformation of the product can be prevented.

In addition, since the product guide door 13 opens at an acute angle with respect to the heating chamber 11 in its maximum open state, compared to opening the product guide door at a right angle or more, the horizontal dimension from the heating chamber can be shortened, resulting in space savings. .

As is clear from the above embodiments, the heating chamber door opening/closing device of the vending machine of the present invention is provided at the rear of the heating chamber provided in the main body so as to be freely openable and closable, and allows products to be smoothly transported from the guide chute located above. A product guide door whose lower end is pivoted to lead the product guide into the heating chamber, an actuation arm with a pin slidably fitted into a long hole provided on one side of the vertical wall of the product guide door, and the actuation arm. While fixing the other end, position the shaft above the shaft support of the product guide door, and move the elongated pin from the shaft support side of the guide door to the opposite shaft support side to move the product guide door toward the heating chamber. a drive motor that opens at an acute angle, a circular cam plate having a closing end groove and an opening end groove on its outer periphery that operate an opening/closing end switch that is rotated by the drive motor and stops the drive motor; It consists of a small door for taking out products provided at the front of the chamber, and the small arc-shaped part formed by the grooves of the cam plate is used as the opening operation part of the product guide door, and the large-angle arc part This is a closing operation part, and when introducing the product into the heating chamber, the pivot side of the product guide door is pushed open, so it opens quickly to a predetermined angle with a small rotation angle, so the product can be reliably introduced.

In addition, when the product guide door is closed, the pin moves in the long hole to the opposite shaft support side of the product guide door and then returns, so the closing time is lengthened and the product guide door closes slowly. This prevents the product from bouncing through the product guide door and guides the product to a fixed position in the heating chamber.

Furthermore, this operation can be easily performed by using the arcuate surface of the cam plate that stops the drive motor, and the maximum open state of the product guide door is at an acute angle with respect to the heating chamber, which saves space. I can figure it out.
