The operation of the product discharging device of the vending machine configured as described above will be described below.

First, the bucket 22 shown in FIG. 7 is indicated by a one-dot chain line during the waiting period, and the solid line is provided at the product storage shelf 2 when the product storage shelf 2 for the selected product 6 is stopped by a switch (not shown). The state where the product 6 is discharged into the bucket 22 by the horizontal delivery device is shown. Next, the product selling operation will be described. When the discharge of the product 6 from the product storage shelf 2 is completed, the motor 19 rotates in the reverse rotation (b) direction shown in FIG. 11, and the connecting plate 23 connected to the chain 17 is removed. Then, the guide lift 26, the support plate 22c, and the bucket 22 come down to the lowest stage. And the horizontal state A of the bucket 22 (Fig. 11)
Then, when the motor 19 further rotates in the reverse rotation (b) direction, the connecting plate 23 connected to the chain 17 moves downward in the column 12 while contacting the roller 24. As a result, the roller 27 attached to the holder 25 separates from the stopper 26d of the guide lift 26 connected to the bucket 22,
The bucket 22 is brought into a free state. When the connecting plate 23 is further lowered, the second roller 29 is guided to the recessed portion 30 'of the guide roller 30, and the first roller 28 is guided by the guide plate 32 and the support column 12.
With the back surfaces 12'a and 12'b of the flanges as the axes, the roller 27 reaches the position of the circular arc portion 26b of the guide lift 26, so that the bucket 22 begins to incline gently due to its own weight and is in the B state. When the connecting plate 23 further descends, the guide lift
By passing over the circular arc portion 26b of the roller 26, the roller 27 is also rapidly inclined greatly, and the C product delivery and the waiting state are set. Therefore, the products 6 in the bucket 22 pass through the chute 35 and are delivered to the product outlet 9a. At the same time, the power supply circuit is turned off by the connecting plate 23, the fixed plate 23b and the switch 34 (shown in FIG. 8) to stop the motor 19. The product take-out door 9 (shown in FIG. 5) is released (not shown) immediately before returning to the waiting state. The product delivered to the product outlet 9a can be taken out by the purchaser by opening the product takeout door 9. The operation of raising the bucket 22 from the standby state C (FIG. 11) of the bucket 22 when the product 6 is purchased is performed in the reverse order of the lowering operation.

Problems to be Solved by the Invention However, in the above configuration, when the bucket 22 carries the product 6 and descends and dispenses it in the state of inclination C, the inclination angle of the mounting plate 22a of the bucket 22 is gentle, Stops on the placing plate 22a or the chute 35, and the product outlet 9a
Sometimes it didn't come out. In order to prevent this, the inclination angle of the mounting plate 22a, that is, the inclination angle of the bucket 22 may be made steep. Then, when the goods on the lowest goods storage rack 2 are put on the bucket 22, The horizontal position state A (FIG. 11) of 22 is higher than the lowest goods storage rack 2, and the goods are not loaded on the bucket 22. Further, it is structurally unreasonable to make the inclination angle steep. Therefore, the above problem remains.

In view of the above problems, the present invention provides an automatic vending machine for multi-product sales, which can reliably convey a product to a product outlet without stopping it on a placing plate or a chute.

Means for Solving the Problems In order to solve the above-mentioned problems, the product discharge device of the vending machine of the present invention is provided with an auxiliary chute which is provided with a shaft in front of the placing plate of the bucket and extending rearward. A projecting piece extending downward at the rear part of the chute and a through hole through which the projecting piece passes on the mounting plate, and a projection provided on the lower bottom part of the bucket for coming into contact with the projecting piece when the bucket descends and leans forward. Is.

The present invention has the above-described structure, and when the bucket descends and leans forward, the projection of the auxiliary chute comes into contact with the projection provided on the lower bottom portion of the bucket, so that the auxiliary chute is centered on the front of the bucket mounting plate. With the forward tilting movement of the bucket, the rearward tilts toward the product outlet side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An article carrying-out device for an automatic vending machine according to an embodiment of the present invention will be described below with reference to FIGS. Omit it.

In the figure, 36 is a bucket of the present invention, 37 is an auxiliary chute, the front end is curled so that the shaft pin 38 penetrates, and a protruding piece 37a extending downward is welded to the rear center part. Further, the auxiliary chute 37 has flange portions 37b at the left and right ends. And the mounting plate 3 of the bucket body 39
Round holes 39a are provided in front of the flanges 39 "a on both ends of 9a,
The curling portion 37c of the chute 37 is connected to the flange portion 3
It is inserted between 9 "a and is rotatably supported by a shaft pin 38. Further, the shaft pin 38 is secured by a fixing metal fitting 40 after passing through.
Further, a through hole 39'a is provided in the rear portion of the mounting plate 39a so that the projecting piece 37a of the auxiliary chute 37 penetrates, and the projecting piece 37a normally projects downward from the through hole 39'a. 39b is a cover plate that is shorter than the placing plate that covers the upper side of the product as in the conventional case. Reference numeral 41 is a protrusion fixed to the rear of the chute 35 by a screw 42, and is mounted at a position where the bucket descends and the projection piece 37a of the auxiliary chute 37 just abuts when leaning forward.

The operation of the product discharge device of the vending machine configured as described above will be described below.

First, the bucket 36 shown in FIG. 1 is shown in a stand-by state by a one-dot chain line, and the solid line is elevated to show the product storage rack 2 with the selected product 6.
At this point, when stopped by a switch (not shown), the product is discharged onto the auxiliary chute 37 of the bucket 36 by the horizontal sending device (not shown) provided in the product storage rack 2. Then, when the discharge from the product storage rack 2 is completed, the product descends in the same manner as the conventional one and descends to the bottom. At this time, the flange portion 37b of the auxiliary chute 37 is in contact with the mounting plate 39a and is in a horizontal state. Then, when the bucket 36 rotates in the reverse rotation (b) direction from the horizontal state A in FIG. 4 and tilts forward, the projecting piece 37a of the auxiliary chute 37 comes into contact with the projection 41, and the auxiliary chute 37 accordingly. The rear starts to lift with the shaft pin 38 as the fulcrum. (State of B). Further, the motor rotates in the (B) direction, the bucket tilts forward, and the auxiliary chute 37 also tilts forward. Then, the product of C and the standby state are set. Further, the protrusion 37a has a through-hole 39'a in the mounting plate 39a even if the auxiliary chute 37 is lifted up by the curl portion 37'a of the protrusion 37a hitting the back surface of the mounting plate 39a.
There is no way out. In this way, the products 6 in the bucket 36 pass through the chute 35 and are dispensed to the product outlet 9a. Then, as in the conventional case, the product 6 delivered to the product outlet 9a can be taken out by the participant by opening the product taking-out door 9. Incidentally, the operation of raising the bucket 36 from the standby state C (FIG. 4) of the bucket 36 at the time of purchasing the product 6 is in the reverse order of the lowering operation. 37 will also be horizontal and will continue to rise.

As described above, according to this embodiment, as the bucket 36 descends and moves forward, the projection 37a of the auxiliary chute 37 abuts the projection 41 of the chute 35, and the rear of the auxiliary chute is lifted, and the tilt angle of the bucket body 39 increases. The tilt angle of the auxiliary chute that has been lifted is larger than that of the conventional one. Also, the product tends to slip due to the reaction when the auxiliary chute 37 is lifted. In this way, the inclination angle is large and the reaction can be used to ensure that the product is an auxiliary chute.
It is possible to pass through the 37 and the chute 35 to the product outlet 9a.

As described above, according to the present invention, the mounting plate of the bucket body is provided with the auxiliary chute which extends rearward about the front of the mounting plate as an axis.
At the rear of this auxiliary chute, there is a protruding piece that extends downward,
When the bucket descends and moves forward, the projecting piece comes into contact with the protrusion provided on the lower bottom of the bucket, and the auxiliary chute is lifted backward together with the bucket, so that the product tilt angle is equal to the tilt angle of the auxiliary chute. The product becomes large and the product slips easily, and the product can be reliably delivered to the product outlet.

In addition, the projecting piece of the auxiliary chute comes into contact with the projection to recoil when the auxiliary chute is lifted, so that the product easily slips.

Further, with such a structure, the inclination angle can be increased without changing the position of the lowermost product storage shelf and the structure is reasonably possible, and the product can be reliably delivered to the product outlet.
