[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a vending machine that can store a large number of products of various types.

(Prior Art) Conventionally, there has been known a vending machine in which a bucket is formed of a box with an open top, and the product inside the housing is conveyed to a product outlet by raising and lowering the container (Japanese Patent Laid-Open No. 1983-1993). −46195).

(Problem to be Solved by the Invention) However, in the vending machine, when the bucket container moves upward, the hand becomes stuck between the bucket container and the product outlet, causing serious injury to the hand. There was a fear that this would happen.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to provide a vending machine that does not cause serious injury to hands when taking out products.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an elevator with a bucket for transporting products inside the vending machine body, and uses the bucket to transport the products to the product outlet. In the vending machine, a plurality of product storage shelves are provided at predetermined intervals on both sides of the travel path of the bucket, and products are placed on each storage shelf and the products are transported to the travel path of the bucket. Each storage shelf has one end on the rear side of the vending machine main body tilted downward, and the bucket is formed into a substantially U-shaped cross section, and a conveyor is provided on both sides of the bucket. is provided with a carry-in port opposite to the carry-out side of each of the storage shelves, and a transport port to the product take-out port is provided on the front side of the bucket, and products are placed near the rear ends of the top and bottom plates of the bucket. Through-holes through which the light emitted from the optical sensor that detects whether or not the bucket is accommodated are provided vertically to face each other, and approximately the center of the bottom plate of the bucket is connected to the chain of the elevator above and below via a connecting rod. The present invention is characterized in that it is attached so as to be rotatable in the direction, and that a biasing means is provided on the connecting rod for biasing the bottom plate to be positioned horizontally.

(Function) According to the present invention, each storage shelf has one end on the rear side of the vending machine main body inclined, so products are placed on the rear of each storage shelf, and when the conveyor is driven, the bucket is used. Products are stored in the rear side of the bucket through the loading port. At this time, the emitted light from the optical sensor passing through the bucket bag passes through the rear side of the bucket bag through the through hole, and the emitted light is reliably blocked by the imported goods. Also,
A conveyance port to a product outlet is provided on the front surface of the bucket, and approximately the center of the bottom plate of the bucket in the front-rear direction is attached to the chain of the elevator via a connecting rod so as to be rotatable in the vertical direction. Since a biasing means is installed to urge the bottom plate to be positioned horizontally, when inserting your hand into the product takeout port and taking out the product in the bucket, the bucket moves upward and your hand reaches the product takeout port. Even when it is held between the bucket and the bag, the bucket can rotate in the vertical direction and the hand can be easily removed.

Through holes 52a are provided on both sides of the top and bottom plates of the bucket bag 52 in the width direction and near the rear ends, respectively, in correspondence with the upper and lower sides. Further, on both sides of the bucket bag 52, there are provided entrances facing the delivery side of each storage shelf 60, which will be described later, and on the front side of the bag bag 52, there is provided a conveyance port to the product outlet 45. Furthermore, one end of the connecting rod 53 is attached to the chain 51 so as to be in a horizontal state, and the other end is pivotally attached to approximately the center of the lower surface of the bottom plate of the bucket bag 52 in the front-rear direction so as to be freely rotatable in the vertical direction. An attached spring (not shown) urges the bottom plate of the bucket bag 52 to be horizontally supported on the connecting rod 53.

Reference numeral 60 denotes a horizontally long product storage shelf installed in multiple stages on both sides of the elevator 50. A product stopper 62 having an L-shaped cross section is attached to one end of the vending machine main body 40 on the back plate 40a side, and the one end is located at the bottom. It is installed tilted so that it is located on the side. Further, a conveyor 61 is attached to the storage shelf 60 to place the products and simultaneously move the products in the direction of the elevator 50.

Reference numeral 70 denotes a chute attached to the lower side of the storage shelf 60 at the lowest stage, and one end in the direction of the door body 41 is lowered and inclined. Also, near one end of the chute 70 is a stop switch 7 that stops the operation of the elevator 50 when the bottom plate of the bucket 52 comes into contact with it.
1 to the through hole 52a of the bucket 52 near the other end.
Insertion holes 72 are provided at positions corresponding to the respective holes.

80 is a light source that emits light; 81 is a light receiving element that receives the light; both constitute an optical sensor that detects whether a product is stored in the bucket 52; the bottom plate of the bucket 52 is connected to the connecting rod 53; The conveyor 61 is installed so that the emitted light reaches the light receiving element 81 when the conveyor 61 is in horizontal contact with the light receiving element 81, and when the emitted light is blocked, the operation of the conveyor 61 is stopped and the bucket belt 52
is set to move downward.

Reference numeral 90 is a shutter installed inside the product outlet 45, 100 is a motor that reversibly drives the endless chain 51 via the connecting chain 101, and 110 is a cam switch installed at the bottom of the endless chain 51. The stop position of the bucket 52 is detected. 120
is a stopper of the bucket 52, which is formed slightly above the other end of the chute 70 and protrudes inward.

Incidentally, 130 is a serpentine rack, and products can also be transported by the serpentine method.

Since the present invention is constructed as described above, a coin is inserted through the coin slot 43 and the product selection button 44 is pressed.
When is pressed, the motor 100 is driven, and the bucket 52 is raised to a predetermined position, for example, the position of the storage shelf 60a, and then stopped by the action of the cam switch 110. At this time, an operating switch (not shown) for the conveyor 61a is operated and the conveyor 61a is operated, so that the product D moves toward the bucket 52 and is stored in the bucket 52 through the loading port. At the same time as the product D passes through the through hole 52a, the light emitted from the light source 80 is blocked, the operation of the conveyor 61a is stopped, and the motor 100 rotates in the opposite direction to lower the bucket 52. As the bucket cart 52 descends, one end of the bottom plate of the bucket cart 52 collides with the stopper 120, and the connecting rod 53 also collides with the stopper 120.
Bucket 5 centering on the other end against the elastic force of the spring.
2 rotates counterclockwise, the bottom plate of the bucket 52 becomes inclined, and the other end comes into contact with the chute 70. As a result, the products stored in the bucket 52 are delivered to the shutter 90 side through the transport port, and the tip of the bottom plate is connected to the stop switch 7.
1, the drive of the motor 100 is also stopped. Then, the shutter 90 is opened and the product D is taken out from the product outlet 45.

In this way, the goods D can be carried out by vertically moving the bucket cart 52 attached to the elevator 50 and driving the conveyor 61a of each storage shelf 60.

Furthermore, since each storage shelf 60 is installed at an angle so that one end on the back plate 40a side of the vending machine main body 40 is located on the lower side, products are always kept by gravity on the back plate 40a of the vending machine main body 40. The product is moved to the side and held by the product stopper 62, and even if some impact is applied from the outside, it will not fall from between the door body 41 and the storage shelf 60, and spacers etc. can be installed to prevent it from falling. Not needed.

Further, as described above, since each product is placed at the rear of each storage shelf 60, the product is stored at the rear side of the bucket 52 when the conveyor 61a is driven. Therefore, the product is the baguette 52.
Whether or not it is accommodated in the interior can be accurately detected by the light emitted from the optical sensor passing toward the rear side. Furthermore, when goods are stored on the front side of the bucket 52, there is a risk that the bucket 52 will rotate counterclockwise against the elastic force of the spring and cause the goods to fall. points are also prevented.

Furthermore, a transport port to the product outlet 45 is provided on the front surface of the bucket bag 52, and the bottom plate of the bucket bag 52 is attached to the endless chain 51 of the elevator 50 via a connecting rod 53 so as to be freely rotatable in the vertical direction. In addition, since a spring is attached to the connecting rod 53 to position the bottom plate horizontally, when the hand is inserted into the product outlet 45 and the product in the bucket 52 is taken out, the bucket 52 moves upward. Then, the hand moves between the product outlet 45 and the bucket 5.
2, even if the bucket is interposed between
2 rotates in the vertical direction, allowing you to easily remove your hand, and there is no risk of causing major damage to your hand.

Incidentally, in the above embodiment, the through hole 52a of the bucket 52 is
Although a vending machine has been described in which four or more through holes 52a are provided in the bucket bag 52, at the same time, three or more light sources 80, light receiving elements 81, and insertion holes 72 are provided, and from the storage shelves 60 arranged in parallel. Storage of transported products may be detected more accurately.

(Effect of the invention) As explained above, according to the invention, each storage shelf has one end on the rear side of the vending machine main body inclined, and the light emitted from the optical sensor passes through the rear side of the bucket. The products transported to the rear of the bucket by the drive of the conveyor are reliably detected by the optical sensor, allowing the vending machine to operate properly. In addition, the bucket can be rotated about the approximate center of the bottom plate in the front and back direction, but as mentioned above, the products are carried out to the rear side of the bucket.
It is possible to prevent the product from falling due to transporting the product to the front side of the bucket. Furthermore,
A conveyance port to the product outlet is provided on the front surface of the bucket, and approximately the center of the bottom plate of the bucket in the front and back direction is attached to the chain of the elevator via a connecting rod so as to be freely rotatable in the vertical direction. Since a biasing means for urging the bottom plate to be positioned horizontally is installed, when inserting a hand into the product takeout port to take out a product in the bucket, the bucket moves upward and the hand is placed in the product takeout port. Even if you get caught between the bucket and the bucket, the bucket can rotate in the vertical direction and you can easily pull your hand out, so your hand will not be damaged and the vending machine has improved safety. It has the advantage of being able to provide
