Abstract

PURPOSE:To prevent commodities from being deformed by connecting locking members respectively pivoted on both the inwalls of a commodity storing column through a link so that commodity pressing parts under the locking members are extruded into the storing column at the same degree of extrusion. CONSTITUTION:At the time of sending operation of a commodity by a sending member 33, a lock control cum 15 is abuted upon a locking member 18B ar ranged on the commodity storing column 11A side so as to abut the member 18B into the storing column 11A. The other locking member 18A also is similar ly extruded into the storing column by interlocking operation and the succeeding stage commodity 35b is locked from its both sides by pressing parts 40a, 40b so as not to drop the commodity 35b. The degree of extrusion of both the pressing parts 40a, 40b is the same and the commodity 35b is locked from both sides with uniform force. Consequently, the case of the commodity can be prevented from being deformed, flawed or damaged.

Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a vending machine, and in particular a vending machine suitable for selling bowl-shaped or trapezoid-shaped products such as cup ramen and containerized yogurt. Regarding.

(B) Conventional technology Conventionally, a storage column that has an opening for filling products in the front and stacks and stores products in a row has a storage column that extends into the storage column and holds the lowest product on the side of the door. A delivery member is provided that rotates downward to drop and send out the product when the product is sent out, and a storage unit is located above the delivery member and rotates and extends into the storage column when the product is sent out to carry the next product to the opposite side. There is a known product dispensing device for a vending machine that is provided with a locking member that locks between the inside wall of the column (for example, Japanese Patent Laid-Open No. 59-30
Publication No. 188). In addition to improving the locking member shown in Publication No. 2, a regulating member is provided on the inner surface of one side wall of the storage column facing the locking member, so that products packed not only in box-shaped paper containers but also in cylindrical A product delivery device configured to reliably control the delivery of canned products and bottled products has also been proposed as shown in Japanese Patent Application Laid-Open No. 62-295198.

(c) Problems to be Solved by the Invention However, in recent years, the number of types of parts sold has increased, and as a result, containers with various shapes have appeared. Typical examples include bowl-shaped containers for cup ramen noodles, and yogurt products in trapezoidal containers. As described above, when selling products having a special shape that is neither box-like nor circular, the devices shown in the above-mentioned publications are insufficient.

In other words, in the devices shown in each publication, one locking member locks the next product by pressing it against the inner wall of the other column, so products with this kind of special shape have a stronger pressing force than one side. This is undesirable because the holding tends to become unstable and the container is likely to be damaged.

The present invention has been made in view of the above points, and is capable of evenly holding products with special shapes from both sides.
To provide a product delivery device capable of smoothly selling products without deforming the product and damaging its value.

(d) Means for Solving the Problems In order to solve the above problems, the present invention provides an opening in the storage column that has an opening for filling products in the front and a storage column that has an opening in the lower side of the storage column for stacking and storing products in a row. A delivery member is provided which extends to place and lock the lowest product, and rotates downward to send out the product by dropping it. In a vending machine that is provided with a locking member that extends and locks the next product between an inner wall of an opposing storage column, the locking member is attached to each side wall of the storage column at the upper part thereof. These locking members are rotatably supported and arranged opposite each other, and each of these locking members is provided with a product holding part bent inward from each other at the lower part of the locking member. Both locking members are connected via a link that extends to the same degree of protrusion and operates in conjunction to lock the next product from both sides.

(E) Function The present invention provides that a pair of product locking members connected by a link extend inwardly from both sides of the storage column when sending out the product.
Lock the next product from both sides. At this time, the product suppression part at the bottom of the locking member that locks the product extends into the storage column with the same degree of protrusion, so even bowl-shaped or trapezoidal products are held with equal force on both sides. To securely hold a product without causing deformation, scratches, damage, etc.

(f) Example Embodiments of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a vending machine main body, on the front of which a front door 2 is pivotally supported by upper and lower hinges 3 and 4 so as to be openable and closable. The front door 2 has an outlet 5 for taking out sold products, and a plurality of product storage sections 6 are arranged inside the vending machine main body 1. The handle 8 is used to pull out the product storage section 7 as shown in the double-dot chain Ia diagram during loading or maintenance. Reference numeral 9 denotes a product chute through which products sold from the product storage section 6 pass until they reach the outlet 5.

Next, the explanation will be continued with reference to FIG. 2 showing the internal structure of the product storage section 6, FIG. 3 showing the sales mechanism, and FIG. 4 showing the operating state thereof.

A rotary drive shaft 10 is vertically arranged in the center of the product storage section 6, and product storage columns IIA and IIB are arranged on both left and right sides of the rotary drive shaft 10. The product storage columns IIA and 11.8 stack and store bowl-shaped products such as cup ramen noodles, or products 36 containing yogurt or the like in trapezoidal containers. The rotary drive shaft 10 is rotated by a drive motor 12,
The instant motor 12 and the rotary drive shaft JO are connected via a joint 13 and a spring pin 14 thereof.

As shown in FIG. 3, an oval-shaped G-lock control cam 15 is fixed to the lower part of the rotary drive shaft 10, and a fan-shaped delivery control cam 16 is fixed to the lower end. There is.

By the way, in the left product storage column IIA, the lower portions of the side walls 17a and 17b, that is, the portions facing the locking control cam 15, are partially cut out, and the locking member 1. 8A and 18B are rotatably provided. The locking members 18A and 18B are connected to the side walls 17a and 17b on both sides of the product storage column 11A in a manner that corresponds to the locking control cam 15, and the upper ends of the locking members 18A and 18B are rotatably mounted on support shafts 19°2.
The pressing part 40a is pivoted at 0 and is bent at the lower part.

40b is provided. And both locking members 18A,
] 8B is connected with a link 21 on one side thereof, and is connected to the locking member 18A with a pin 22 on the left end below the support shaft 19, and to the locking member 18B with a pin 23 on the right end. They are connected above the support shaft 20. Here, the pins 22, 23 are provided at the same distance from the support shaft 19, 20, respectively. In this way, the locking members 18A, 18B connected by the link 21 are configured such that the locking control cam 15 rotates in contact with the back surface of one of the locking members 18B, so that both the locking members 18A, 18B can store the product. It is operated in a state in which it protrudes into the column IIA and locks and holds the cooked rice product 35b from both sides thereof, and a state in which it exits out of the opening and releases the product holding. And the locking members 18A and 1.8B on both sides
are connected by pins 22.23 located at the same distance from the supporting shaft 19.20, which is the fulcrum of the locking member 1.
When 8A and 18B operate to open the opening, the pressing part 4
0a and 40b protrude into the product storage column 11A at the same inclination angle and the same protrusion degree.

Similarly, in the product storage column on the right], ], B,
Locking members 25A and 25B connected by a link 24 are rotatably supported by a support shaft 26°27. There is also a product pressing part 41a at the bottom of these locking members 25A and 25B.
, 41b are formed. 17c and 17b are side walls of the product storage column IIB. Then, the locking members 25A, 2 are connected by pins 29.30 provided at both ends of the link 24.
It is combined with 5B. By the way, the rotational drive shaft 10
A shaft 31 placed directly above the delivery control cam 16 attached to the
．． 32 is provided with delivery members 33,34. The delivery members 33 and 34 are supported on the lower surface by the delivery control cam 16, and are arranged approximately horizontally in each of the product storage columns IIA and II.
The lowest product of the products stacked and stored in a line in the product storage columns IIA and IIB can be placed and locked, and when the support by the delivery control cam 16 is released, each product can be rotated downward. It is designed to move and send out the lowest-ranked products.

The operation of the above configuration will be explained.

FIG. 2 shows a state in which products are sold from the left product storage column IIA, and the external appearance of the same state is as shown in FIG. Now, in FIG. 3, it is assumed that the delivery control cam 16 rotates clockwise, and in a state before 1/4 rotation from the illustrated position, the delivery control cam 16 moves both the thread sending members 33, 3.
4 is horizontally locked and held on top of each storage column II.
A.The lowest grade products of IIB are listed. This situation is as shown in FIG. 2, where the delivery member 33 of product storage column IIA is indicated by a chain double-dashed line, while the delivery member 34 of product storage column IIB is shown by a solid line. Then, when the delivery control cam 16 rotates 174 times from this standby state to the state shown in FIG. 3, the delivery member 33 rotates downward and opens as shown in FIG. 2, and the product 35a is dropped. At this time, product storage column]]
The lowest product 36a on the B side is still the delivery control cam 16.
Since the delivery member 34 is prevented from rotating, it does not fall.

On the other hand, the locking control cam 15 is operated by the locking member 18 on the side of the product storage column IIA when the sending member 33 is in the delivery operation of the product.
It comes into contact with B and is pushed inward into the storage column. As a result, the other locking member 18A is similarly operated by the link 21 so as to extend into the storage column, and as shown in FIG. Lock it from both sides to prevent it from falling. At this time, the degree of protrusion of the pressing parts 40a and 40b is the same, and the product 35b is locked from both sides with equal force, so that the container will not be deformed, scratched, or damaged. After this, each cam 15, 16 rotates another 174 revolutions from the state shown in FIG. 3 and then stops. At this time, the delivery control cam 16 rotates the delivery member 33 upward, and both delivery members 33, 34 are held horizontally. On the other hand, since the locking member 18B is no longer suppressed by the locking control cam 15,
The products after the next stage product 35b fall, and the delivery member 33"
Listed in second place.

In this way, I wait at the rice vendor.

Each cam 15. ], while 6 rotates clockwise, the product storage column] IB performs the same operation as described above.
The lowest product 36a on the side is sold.

(G) Effects of the Invention According to the present invention, as described in 2., the locking members pivotally supported on the inner side walls of the product storage column are such that when the product is sent out, the product suppressing portion of the part of the locking member is inside the storage column. The links are connected so that they extend to the same degree of protrusion, so even if the product is bowl-shaped or trapezoidal, both sides of the product are locked with equal force, preventing the product from being deformed, scratched, or damaged. There's nothing to do.
