Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a product delivery device for a vending machine having a mechanism for storing cylindrical products such as bottles and cans in a horizontal state and dropping them sequentially from the bottom. Regarding.

(Prior art) Conventionally, mechanisms for storing and transporting cylindrical products horizontally are disclosed in Japanese Patent Application Laid-open No. 55-88194 and Japanese Utility Model Application No. 58-1.
The one shown in No. 3387 is known.

The former product delivery device includes a driving motor, a pair of sprockets, an endless chain wound between the sprockets, a plurality of shelves attached to the chain at predetermined intervals, a product receiving tray installed below, and It consists of a chute.

Therefore, when selling products, the chain is rotated up and down by the motor, and the product on the shelf that has moved to the lowest position is received in the tray.The tray is then rotated by the motor and falls onto the chute, and the product is placed on the tray. It is sent to the extraction port. Furthermore, when the product is on standby for sale, the above-mentioned saucer blocks the space between each product and the outlet, so that even if the user inserts his or her hand through the outlet, the product cannot be pulled out.

On the other hand, the latter product unloading device has the same chains, shelves, etc. as the above-mentioned device, and a flapper that opens only downwards is installed in the path where the product falls, and this flapper prevents the product from being removed from the outlet. Ru.

(Problem to be solved by the invention) However, since all conventional product delivery devices use a chain elevator mechanism, they require chains, sprockets, many shelf boards, etc. If the product gets caught, there is a risk that the product will not be able to be removed, and a flapper or the like is essential to prevent the product from being removed.

The present invention has been made in view of the above circumstances, and its purpose is to provide a vending machine that can reliably transport products with a simple mechanism without requiring a separate anti-theft flapper, chain, sprocket, etc. The goal is to provide equipment.

(Means for Solving the Problems) In order to achieve the above object, the product dispensing device for a vending machine according to the present invention is provided with recesses that are arranged facing each other and that cooperate in the vertical direction inside each other to sandwich the product. and a fixed shelf and a movable shelf in which convex portions are formed alternately, a guide member that supports the movable shelf in a vertically movable manner, a driving source, and a movable shelf that moves vertically within a predetermined range with the driving force from the driving source. It is comprised of a release mechanism that releases the clamping state of each product for a predetermined period of time.

(Function) With these configurations, when the vending machine is in standby mode, each product is held between the convex part of the fixed shelf and the concave part of the movable shelf, so even if you put your hand in from below. I can't remove the product.

Next, when the product is sold, a release mechanism such as a cam or a link is also operated by a drive source such as a motor, and when the release mechanism is released for an initial predetermined period of time, the movable shelf is moved along the guide member within a predetermined range, that is, the four parts thereof. and the four parts of the fixed shelf are facing each other. Since the distance between the fixed shelf and the movable shelf is now slightly larger, each product moves downward in sequence, and the product at the lowest position falls and is sent to the product outlet of the vending machine.

Furthermore, after a predetermined period of time has elapsed, the movable shelf rises and returns to its original position, so that the concave and convex parts face each other, and each product is clamped while being lowered one pitch at a time, and the motor is stopped. .

(Example) Figures 1 to 3 show a product delivery device to which the present invention is applied. Figure 1 is an internal front view, Figure 2 is an internal side view, and Figure 3 is an exploded perspective view thereof. 1, the product delivery device is composed of a fixed shelf 1, a movable shelf 2, a guide cover 3, a motor 4, and a cam plate 5.

Convex portions 6a and concave portions 6b are formed alternately in the vertical direction on the inner surface of the fixed shelf 1, and in this embodiment, a flat plate and an uneven plate are integrally combined. A hook 7 is bent and formed at the upper end of the fixed shelf 1. As shown in FIG. It is installed in the predetermined position of 8.

Like the fixed shelf 1, the movable shelf 2 has a convex portion 10a and a concave portion 10b on its inner surface, and elongated holes 11, 12 are provided on both side surfaces and the upper rear surface. Moreover, as can be seen from FIG. 1, each convex part 10a of the movable shelf 2 faces the four parts 6b of the fixed shelf 1,
The four parts 10b face the convex part 6a of the fixed shelf 1, and products A, B, C, etc. are held between the convex part 6a and the concave part 10b.

The guide cover 3 has a U-shape that covers both sides and the back of the movable shelf 2, and has a plurality of screw holes 13 on both sides and a hook 14 at the upper end. A guide pin 15 is screwed into each screw hole 13, and the tip of the guide pin 15 is fitted into the elongated hole 11 of the movable shelf 2. The hook 14 is locked to a hook receiver 16 at the inner upper end of the frame 8, thereby connecting the guide cover 3 to the frame side and allowing the movable shelf 2 to move up and down along the elongated hole 11.

The motor 4 is fixed to the upper inner surface of the guide cover 3, and a circular cam plate 5 is connected to the motor shaft 4a to release the clamping of the product. A cam pin 5a is protruded from the front side of the cam plate 5 near the periphery, and the tip of the cam pin 5a is inserted into a long hole 12 on the back side of the movable plate 2. Therefore, when the cam plate 5 is rotated by the motor 4, the movable shelf 2 is moved by the cam pin 5a.
It will move up and down.

On the other hand, at the lower end of the movable plate 2, as shown in FIGS. 3 and 4, a shutter plate 17 is installed to prevent theft and detect the removal of goods. The shirt shirt plate 17 has a rear end bent slightly downward and is rotatably attached to a support shaft 18. Of course, the rear end of the shirt top plate 7 may be straight or may be bent slightly upward, as long as it does not interfere with the dropping and carrying out of the lowest order product A. Further, the shirt flap plate 17 is urged upward by a torsion spring 19, and its rear end hits the stopper pin 27 and is stopped. Stopper bin 2
A microswitch 20 is installed above 7, and its actuator arm 20a is activated by rotation of the shutter plate 17.
is pressed and the falling product is detected.

As shown in FIG. 2, an inclined chute 21 is installed below the shirt cover plate 17, and the tip of the chute 21 communicates with a product outlet 22. The product outlet 22 is closed by a rotary flapper 23, and the upper end of the flapper 23 is attached to the lower end of the inner door 24. An outer door 25 is attached to the front of the inner door 24 so that it can be opened and closed, and a product sample,
A coin slot, product selection buttons, etc. (not shown) are arranged.

In addition, in this embodiment, a light emitting element 2 is placed above the product storage section.
6a, a light-receiving element 26b is attached to the bottom, and when the product runs out, the light-receiving element 26b detects the light from the light-emitting element 26a and issues a sold-out signal. For this reason, light transmission holes 17a and 21g are formed in corresponding positions in the shutter plate 17 and the chute 21, respectively.

FIGS. 6(a) to 6(d) are operational state diagrams of the product delivery device, and the rotational position of the cam plate 5 is shown at the top.

Therefore, in the sales standby state, each of the products A and B is held between the protrusion 6a of the fixed shelf 1 and the four parts 10b of the movable shelf 2, as shown in FIG. 6(a), and is in a stored state. It is in.

Next, when a coin is inserted into the vending machine and the product selection button is pressed, the upper motor 4 and cam 5 (FIG. 3) begin to rotate in the direction of the arrow. Therefore, the movable shelf 2 is lowered by the cam bin 5a, the products A and B are released from being held as shown in FIG. 6(b), and the cam plate 5 is lowered as shown in FIG. 6(e).
When the machine rotates half a rotation, products A and B fall one pitch at a time. When the product A at the lowest position falls, after rotating the shirt cover plate 17 downward, it passes through the chute 21 and enters the product outlet 22.
(FIG. 2), and as shown in FIG. 6(d), the product B moves between the lowermost protrusion 6a and the recess 10. At this point, the movable shelf 2 has changed from descending to ascending, so
The distance between the convex portion 6a and the concave portion 10b is narrowed, so that the product B does not continue to fall by °C.

On the other hand, the shirt flap plate 17 returns to its original position by the action of the torsion spring 19, and at this time pushes the actuator arm 20a (Fig. 4) of the microswitch 20, so that the product A
A detection signal of is sent to a predetermined controller (not shown). After confirming that the product A has been delivered using this detection signal, the controller sends a stop signal to the motor 4, and the cam plate 5
At the same time as it rotates and stops, the movable shelf 2 also returns to the position shown in FIG. 1(a).

Since both sides and the back side of the movable shelf 2 are regulated by the guide cover 3, the movable shelf 2 does not move forward, backward, left or right when moving up and down. In addition, when the vending machine is on standby, the product outlet 22
Even if you try to open the shirt top plate 17 by inserting your hand, the rear end of the shirt top plate 17 hits the product and does not move, so you cannot remove the product. In addition, it is impossible to forcefully open the shirt cover plate 17 by deforming it, or even without the shirt cover plate 17, because the product itself is held between the fixed shelf 1 and the movable shelf 2, so it is impossible to remove the product. be.

FIG. 5 shows a second embodiment of the movable shelf 2. This movable shelf 2 is formed by simply bending a single plate into an uneven shape, and the fabrication of the movable shelf 2 is easier than in the previous embodiment. becomes easier. However, in order to restrict the movement of the movable shelf 2 in the front, back, left, and right directions, it is necessary to install a guide cover 3 (see FIG. 3) around the movable shelf 2 as described above. The rest of the structure is the same as the previous embodiment, and the movable shelf 2 moves up and down by the rotation of the cam plate 5.

In the above embodiment, a cam mechanism is used to release the clamping of each product, but a crank or link mechanism may also be used. Furthermore, instead of the guide cover 3 and guide bin 15, guide rails or the like may be installed on both sides of the movable shelf 2 to allow the movable shelf 2 to move up and down. Furthermore, if a plurality of guide rollers are provided inside the fixed shelf 1 and the movable shelf 2, each product can move smoothly without getting caught.

(Effects of the Invention) As described in detail above, in the product delivery device for a vending machine according to the present invention, the fixed shelf and the movable shelf, each having a concave portion and a convex portion inside, move relative to each other to clamp and take out the product. Therefore, chains, sprockets, numerous product shelves, and even anti-theft flappers can be omitted, and products are reliably conveyed to the outlet.
