Description

[Detailed Description of the Invention] The present invention relates to a product dispensing device for a vending machine.

In a product dispensing device installed at the lower end of a product storage stocker of a vending machine, when dispensing the product, the second stopper is first projected into the stocker to support the second product from the bottom of the product group in the stocker. After that, the first product that supports the lowest product
The stopper is inserted and the product at the bottom is dispensed. 8 and 9 show a conventional product dispensing device disclosed in Japanese Patent Application Laid-Open No. 54-99770, with FIG. 8 showing the product 51 before dispensing and FIG. 9 immediately after dispensing the product.

In the internal mechanism, as shown in FIG. 8, a front lever 52 abuts against a stop shaft 53 to support the lower side of a front stopper 54. The weight of the product 51 is added to the front stopper 54,
This acts as a force that rotates it downward around the horizontal shaft 55, but at the contact point between the upper end of the front lever 52 and the front stopper 54, a straight line connecting the contact point and the center of the horizontal shaft 55 and the contact point and the horizontal shaft 56 are connected. Since the front stopper 54 is arranged so that the angle it makes with the connecting straight line is an acute angle, the pressing force of the front stopper 54 becomes a force that presses the front lever 52 against the stop shaft 53, and the front stopper 54 does not go down, and at this time, the link 57 and Movable iron core 59 of electromagnet 58
is in the forward position, the horizontal shaft 60 of the front lever 52 hits the rear end of the long hole 61 of the link 57, the front end of the oval hole 62 at the rear of the link 57 hits the horizontal shaft 64 of the lower end of the rear lever 63, and the The stopper 65 is retracted.

When the payout signal is issued, the electromagnet 58 is excited, the movable iron core 59 moves back, and the link 57 connected thereto also moves back against the spring 66. For this reason,
First, the rear lever 63 rotates rearward together with the horizontal shaft 64 in contact with the front end of the elliptical hole 62, and the rear stopper 65 integrated therewith projects to prevent the second product 51 from being dispensed. Until the rear stopper 65 protrudes, the long hole 61 at the front of the link 57 is connected to the horizontal axis 6.
Since the front lever 52 does not move because the front lever 52 only moves along the 0 axis, the front stopper 54 remains protruding and no dispensing is performed, but after the rear stopper 65 protrudes, the movable iron core 59 and the link 57 retreat further. Then, the link 57 moves backward while the horizontal shaft 60 contacts the front end of the elongated hole 61, and the front lever 52 is tilted backward. For this reason, the support of the front stopper 54 is removed, so that the product 5
The front stopper 54 is inserted by the load of 1, and the front lever 52 is further pushed rearward by the front stopper 54 and retreated as shown in FIG.

However, in such a conventional device, the structure for interlocking the stoppers 54 and 55 is that the front lever 52 and the rear lever 63 are provided with horizontal shafts 60 and 64 that engage with the elongated hole 61 and the oval hole 62 of the link 57, respectively. , is a complicated structure in which the front stopper 54 is pivotally supported to the rear stopper 65 by a horizontal shaft 55, and requires at least four horizontal shafts 55, 56, 60, and 64 to be attached during assembly. It is difficult to assemble. Furthermore, solenoids are used in relatively many places, such as product dispensing devices and coin insertion units, but conventionally, the plunger of this solenoid and the actuated body actuated by the solenoid are connected only by the actuated body. After the connecting rod is inserted into the through hole of the actuating body and the plunger head, push nuts for preventing slippage are fixed to both ends of the connecting rod. However, this conventional configuration requires two push nuts and requires annular grooves for fitting the push nuts to be formed at both ends of the connecting rod, which is time-consuming.

Therefore, the present invention provides a product dispensing device that solves these problems.

A lock pin is inserted into the through holes b and 6c so as to be movable in the directions of arrows G and H, and is biased in the direction of arrow G by a spring 50, and the tip is attached to the stocker 3.
By inserting it into a hole (not shown) formed in the side wall of the stocker 3, the product dispensing device 5 is fixed to the lower part of the stocker 3 together with the action of the notch 46 and the pin 47.

The operation of the above configuration will be explained. First, the state shown by the solid line in FIGS. 4 and 5 is a state in which the lowest product 2 is supported by the first stopper 10,
Further, the actuating plate 38 is pushed into the box 6 by the product 2 against the spring 41. In this state, insert the specified coin into the coin slot,
When the product selection button is pressed, the solenoid 30 is activated and the plunger 31 is pulled up in the direction of the arrow. As a result, the second stoppers 19 and 20 are rotated about nine rotations of the support shaft in the direction of arrow J via the connecting rod 35, and the protrusions 19a and 20a are caused to protrude into the stocker 3. At the same time, the guide rod 16 is pulled up along the cam slit 15 via the connecting plate 32, but first the first stopper 10 does not move because it is pulled up vertically along the lower vertical portion 15c. Therefore, the protrusion 1 of the first stopper 10
0c protrudes into the stocker 3, the protrusions 19a, 2 of the second stoppers 19, 20
0a protrudes into the stocker 3 (phantom line in FIG. 5). Next, when both ends of the guide rod 16 are pulled up diagonally along the inclined portion 15b, the first stopper 1
0 is rotated in the direction of arrow A by this guide rod 16, and the protrusion 10c of the first stopper 10 is recessed into the box 6. As a result, the lowest product 2 is dispensed, and the second product 2 from the bottom is supported by the second stopper 19, 20 projections 19a, 20a. Therefore, only the lowest product 2 is dispensed, and the second product 2 from the bottom and the products 2 stacked above it are not dispensed. Also, the actuating plate 38 is moved to box 6 by product 2.
Although it is pushed inward, it is not pushed in because it hits the stopper piece 45 of the lid 7, and the surface of this actuating plate 38 becomes almost flush with the surface of the lid 7, and once the product 2 is caught in the upper opening 44, it cannot be dispensed. It won't happen. Next, the solenoid 30
When the operation of the first stopper 10 is stopped, the guide rod 16 located at the imaginary line position in FIG.
c is made to protrude into the stocker 3, and at the same time the protrusions 19a, 20a of the second stoppers 19, 20
is inserted into the box 6, product 2 descends inside the stocker 3, and the second product 2 from the bottom is
is supported against the protrusion 10c of the first stopper 10, and enters the payout standby state shown by the solid line in FIGS. 4 and 5. Product 2 in Stockka 3 is the last 1
At this point, since there is no product 2 to press the actuating plate 38, the actuating plate 38 is rotated in the direction of arrow E by the spring 41 and becomes the state shown by the imaginary line in FIG.
The tip of c is the detection part 39a of the limit switch 39
, a message indicating that product 2 is sold out is displayed. Furthermore, when the product 2 in the stocker 3 becomes the last one, the product 2 is lowered and moved to the first stopper 10.
Due to the impact of hitting the protruding part 10c, the product 2 may bounce up or stand at an angle, making it impossible to dispense. This prevents it from tilting or tilting, and it lies sideways on the protrusion 10c of the first stopper 10 in a normal state.

As described above, the product dispensing device of the vending machine of the present invention has the first stopper 10 and the second stopper 1.
9, 20, a guide rod 16, a support shaft 13, a support shaft 9, a connecting plate 32, a connecting rod 35, etc., and each part is connected to three shafts in the box 6, that is, the guide rod 16 and the support shaft 9. Since it is assembled using only the rods 35, the structure is simple and the assembly workability is better than in the past. Furthermore, cam slits 15 of a predetermined shape are formed at appropriate positions on both sides of the box 6,
Since a guide rod 16 is provided whose central portion passes through a proper position of the first stopper 10 and whose both ends are inserted into the cam slits 15, the first stopper 10 that supports the group of products in the stocker 3 is inserted into the box 6. The box 6 is supported by the side walls 6b and 6c, and the back plate of the box 6 is bent into a predetermined cam shape, and the first stopper 10 is moved along the back plate of the box 6 to the stocker 3. Compared to a case where the first stopper 10 is configured to be freely retractable, there are fewer deformed parts, and the first stopper 10 can be retracted and retracted into the stocker 3 in a stable state over a long period of time. Further, the connecting rod 35 is prevented from moving along its axis by the walls of both outer connecting portions, and is restricted from moving along the direction perpendicular to the axis by the plunger, Furthermore, since the distance between the two rotating bodies is regulated by the connecting body, the connecting rod once entered into the long groove and the long hole will not come out through the communicating hole, and the connecting rod will not move out like in the past. There is no need to fix push nuts at both ends of the connecting rod to prevent it from coming off. Therefore, the number of parts is reduced by the amount of both push nuts, and there is no need to perform any processing such as annular grooves on the connecting rod.
It doesn't take much time.
