Description

[Detailed Description of the Invention] The present invention relates to a vending machine having an input port at the upper end, a discharge port at the lower end, and a product conveyance path for relocatably storing cylindrical products inputted from the input port. .

Traditionally, cylindrical products have been stored in this type of product transport path by placing them in a sideways position that allows them to be transferred from an input port that opens at the top of the product transport path, and then allowing them to be transferred and dropped within the transport path in this sideways position. It is configured to be stacked and stored in a row from the bottom end.

Therefore, it is necessary to load the products correctly so that the axis of the cylindrical product is perpendicular to the rolling direction.

However, if a cylindrical product is accidentally introduced with its axis parallel to the rolling direction in a state where it cannot be transferred, clogging will occur in the conveyance path.

For this reason, in order to prevent the product from falling to the back of the conveyance path and causing a blockage even if it is mistakenly loaded, cylindrical sales products can be moved freely, as disclosed in Japanese Utility Model Publication No. 54-8796. A supporting rail is sequentially meandered back and forth to form a serpentine column, and the cylindrical sales item can pass through the serpentine part at the top of the column only when it rotates normally. A known configuration is known in which stoppers are provided at intervals of , and products placed in a non-rolling position are stopped by the stoppers.

However, in this conventional technology, although the stopper prevents incorrectly inserted products that cannot be transferred from entering the back of the conveyance path, there is a drawback that each time the stopper prevents the incorrectly inserted product from entering the conveyance path, the user must insert a hand, arm, etc. from the input port to take out the incorrectly inserted product. there were.

On the other hand, among cylindrical products, when products made of easily breakable containers such as bottled beverage products are loaded into a vending machine provided with this type of product conveyance path, the products tend to break.

In other words, it is easy to load products continuously from the input port, and if products are loaded continuously, when they are transferred and dropped in the conveyance path,
This impact is caused by the repeated collision between the products that are inserted before and after each other, and by the fact that the products that are continuously introduced fall and collide with the products that have already been stored, and are piled up and stored. becomes extremely large.

Therefore, products packaged in bottles tend to crack, and products packaged in cans have the disadvantage of causing denaturation.

The present invention has been devised to eliminate such drawbacks, and provides a product storage device that prevents products from being placed in a position that cannot be transferred into the slot, and also prevents continuous feeding.
Examples will be described below with reference to the drawings.

Reference numeral 1 denotes a vending machine main body, and a door 2 is pivotally supported on the front side so that it can be opened and closed.

3. A product storage shelf provided in the main body 1, in which bendable running members 6 and 7 are arranged side by side and facing each other between side plates 4 and 5 vertically installed at a predetermined interval, and are bent in the vertical direction. An extending product conveyance path 8 is formed.

At the upper end of this product conveyance path 8, there is formed an input port 9, which is an opening for introducing the product into the conveyance path 8, and at the lower end, the product is discharged to a product takeout port 10 provided in the door 2. A discharge port 11 is formed.

This discharge port 11 is provided with a discharge device 12 that controls the discharge of one product per sales command, and 13 is an input port 9.
A control plate 14 having a semicircular cross section is rotatably attached to the running member 6 in the middle, and has a locking part 15 at the front end and an abutment part at the rear end. 16 are constructed so that they can alternately appear and disappear into the product conveyance path 8.

In normal times, the center of gravity is set so that the locking part 15 side is heavier than the abutting part 16 side around the shaft support so that the locking part 15 at the front end comes into contact with the locking part receiver 17 provided on the running member 6. are doing.

Therefore, in this normal state, the locking part 15 is positioned outside the product conveyance path 8, and the waist abutment part 16 projects into the product conveyance path 8.

When the product a is thrown into the input port 9 in a horizontal state in which it can normally roll, the rolling force pushes the product a into the contact portion 16.
The control plate 14 is forced to rotate by coming into contact with the control plate 14.

In addition, the distance between the locking part 15 and the contact part 16 is formed to be smaller than the length dimension 1 of the product a, and the locking part 15 and the contact part 16 protrude into the product conveyance path 8 at approximately the same level. At times, the distance between the distal end of the locking portion 15 and the distal end of the contact portion 16 and the opposing traveling member 7 is made smaller than the diameter of the product a, and the product a is vertically inserted through the input port 9. The structure is such that when the product a is put into the container, the product a cannot pass between the locking portion 15, the contact portion 16, and the traveling member 7 serving as a blocking member.

Reference numeral 18 indicates that the control plate 14 rotates so that the contact portion 16 is connected to the product conveyance path 8.
This is a contact portion receiver that engages with the corresponding contact portion 16 to prevent the control plate 14 from rotating more than a predetermined amount when the control plate 14 escapes to the outside.

In the above configuration, when the product a is thrown in horizontally in a rollable state from the input port 9, it comes into contact with the abutment part 16 that protrudes into the product conveyance path 8, and the product a is moved by the rolling force into the abutment part 16. 16 and press downward.

Therefore, the control plate 14 rotates around the shaft support, and the contact portion 1
6 escapes to the outside of the product conveyance path 8, and the locking portion 15 protrudes into the product conveyance path 8 to prevent the next product a from being thrown in.

Therefore, the product a passes over the contact portion 16 in a normal transferable state, rolls downward in the product conveyance path 8, and is stored, and the control plate 14 allows the product a to pass over the contact portion 16. Contact part 16
When it is released from the locking part 15, the center of gravity is on the locking part 15 side, so it rotates in the opposite direction, and the locking part 15 comes into contact with the locking part receiver 17 and returns to its original state.

In addition, when trying to put product a into the slot 9 in a vertical manner that cannot be transferred, the product a is inserted into the locking part 15 as shown in FIG.
The abutting portion 16 and the running member 7 as a blocking member create a state of locking, and the charging is prevented.

In addition, the control board 1 of the input control device 13 according to the above embodiment
No. 4 is configured so that the center of gravity is on the side of the locking portion 15 to force the return of rotation after the operation by inserting the product, but No. 7
As shown in the figure, an elastic member 19 is provided on the shaft branch of the control plate 14 in a direction that abuts the locking portion 15 and the locking portion receiver 17, so as to force the rotation to return after operation due to product insertion. may be configured.

As described above, the present invention includes a contact part that protrudes from the bottom surface of the slot into the slot and is pushed outward by products placed in a transverse position that can be transferred, and a contact part that protrudes from the bottom surface of the slot to the outside of the slot. a locking part that protrudes into the slot from the lower surface of the slot in front of the loaded product in conjunction with the movement of the product to the slot, and prevents the next product from being inserted; The distance between the upper surface of the input slot and the upper surface of the product is set to be shorter than the length of the product, and the locking part or the contact part and the blocking part in a state where the locking part and the contact part protrude approximately equally into the input slot. Since the distance between the product and the member is set to be smaller than the diameter of the product, it is possible to prevent continuous product loading and product loading in a posture that prevents transfer.

Therefore, it is possible to prevent the products from being cracked or deformed during loading, and also to prevent erroneous loading due to the posture in which transfer is not possible.
