An example of the above-described conventional article unloading device for a vending machine will be described below with reference to the drawings.

In FIGS. 6 to 8, 1 is a main body.
Reference numeral 2 is a door, and 3 is a plurality of product storage chambers provided inside the main body. Reference numeral 4 denotes a content product, which is stacked and stored in the product storage chamber 3. Reference numeral 5 denotes a carry-out mechanism for ejecting the contents product 4. Reference numeral 6 is a lower part guide passage for guiding the contents product 4 thrown out from the carry-out mechanism 5 to the front door 2 side, which is inclined forward from the rear to the front. An internal flap 7 is located in front of the lower guide passage 6 and is rotatably attached to the main body 1. The reference numeral 8 designates a take-out opening, which is located above the door 2 (at the height of the hip bone of an adult) and has a width dimension which is about the size at which the content product 4 can be taken out and is provided close to one side of the door 2. There is. Reference numeral 9 denotes an outlet flap, which is located in front of the outlet 8 and is rotatably attached to the door 2.

Reference numeral 10 denotes a bucket, both ends of which are attached to a vertical conveying device 11 which is attached to the door 2 and moves up and down in front of the inside flap 7. Reference numeral 12 is a belt, one end of which is on the side of the take-out port 8 is fixed to the lower part of the door 2 and the other end is fixed to the upper part of the door 2, bent in a crank shape and slidably engaged with the bucket 10. The dimension of the crank-shaped substantially horizontal portion of the belt 12 is smaller than the height of the take-out port 8 located at the upper portion. A pulley 13 is rotatably attached to the bucket 10 and is located at an engaging portion of the belt 12. 14 is a product holding stage, which is a bucket 1.
No. 0 belt 12 is tilted forward to the lower end fixed side (for example, 40
)), And has a dimension slightly smaller than the width dimension of the take-out port 8 and is attached at a position facing the take-out port 8 at the top. A commodity guide 15 is attached to the door 2 in front of the bucket 12.

The operation of the product unloading device of the vending machine configured as described above will be described below with reference to FIGS. 6 to 8.

The bucket 10 is located at a position facing the inside flap 7 in the standby state, and the contents 4 discharged from the product storage chamber 3 by the discharge mechanism 5 pass through the lower guide passage 6 and push the inside flap 7. Wait for it to open and dive. When the content product 4 is placed in the bucket 10, the vertical transport device 11 raises and the bucket 10 rises. When the bucket 10 rises, the belt 12 engaged with the bucket 10 becomes
The bucket 1 is moved horizontally by the amount of upward displacement of the bucket 10.
Move relative to 0. At this time, the belt 12 is bent and supported by the pulley 13, and the movement resistance is reduced.

When the bucket 10 is lifted, the inner product placed on the belt 12 is lifted and moved horizontally. When the bucket 10 is lifted by the dimension a, the inner product 4 is moved by the horizontal movement of the belt 12 to move the belt 12 to the horizontal position. Moving to the product holding stage 14 provided on the bucket 10 on the lower end holding side,
It is held by the product guide 15 and further rises as the bucket 10 rises. When the bucket 10 rises to a position facing the take-out port 8, the contents holding stage 14 is tilted to drop the contents 4 into the take-out port 8, and the take-out flap 9 is opened and taken out. After that, the vertical transport device 11 makes a downward movement, and the bucket 10 descends. The belt 12 performs an operation reverse to that when the bucket 10 descends, and the bucket 10 descends to a position facing the in-compartment flap 7, and one carrying-out operation ends.

[0009]

However, in the above-mentioned conventional configuration, the bucket 10 cannot be lifted until the content product 4 thrown out from the carry-out mechanism 5 enters the bucket 10 and the inside flap 7 is closed. The time from when the contents product 4 is thrown out to when it enters the bucket 10 is the contents product 4
The maximum waiting time is set because it depends on the type of the product and the position of the carry-out mechanism 5, but the installation state of the vending machine, the difference in product shape, and the contents 4 of the lower guide passage 6 The content product 4 is transferred to the bucket 1 within the waiting time set by the increase of sliding friction resistance due to dirt such as liquid.
When the bucket 10 operates before entering 0, and then the product inside pushes the inside flap 7 open and drops, the product inside 4
Not only is not conveyed to the take-out port 8, but when the bucket 10 descends, the contents 4 dipped in and could not stand by at a predetermined position, and the vending machine could not be put into a sale state.

The present invention is to solve the above-mentioned conventional problems. In a vending machine with a high outlet and a single outlet, even if the contents are jammed in the lower guide passage, the vending machine is not stopped. An object is to provide a product discharge device.

[0011]

In order to solve this object, a product unloading device of a vending machine according to the present invention is provided with a fall prevention plate for stopping the opening and closing of a flap in a refrigerator and a fall of contents products, and a fall prevention plate of the fall prevention plate. It has a lock release device that locks rotation, a return device that puts this fall prevention plate on standby in front of the inside flap, and an operation control unit that operates the carry-out mechanism, the lock release device, and the vertical transport device.

[0012]

With this structure, when the contents are thrown out from the carry-out mechanism, the lock release device operates by the operation control means to enable the fall prevention plate to rotate, and the inside flap is opened and closed to the bucket through the bottom guide passage. The fall prevention plate is rotated and returned to the front position of the inside flap by the return device, and after a predetermined waiting time, the operation of the lock release device is stopped by the operation control means, and the rotation of the fall prevention plate is locked again. The opening operation of the inner flap on the entire surface is hindered, and then the bucket is lifted by the drive of the vertical transport device, but the inside flap is not opened for the inside products that take time to open the inside flap for a predetermined waiting time. Therefore, even if the bucket rises, it does not fall forward from the inside flap, so it does not dive under the bucket and the vending machine does not stop selling. It is possible to transport the contents goods by.
