Description

[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, a vending machine is known in which a bucket is formed of a box with an opening at the top, and the product inside the housing is conveyed to a product outlet by raising and lowering the container (Japanese Patent Application Laid-Open No. 1983-1993). −46195). In addition, in a vending machine in which storage shelves are arranged in two rows and a means for discharging product cases is provided between each storage shelf, the dispensing means is constructed of a stacker crane having a bucket with an L-shaped cross section. (Jitsukai 53-30398
issue).

(Problem to be solved by the invention) However, in the former type of vending machine, when the bucket container moves upward, the hand gets caught between the bucket container and the product outlet, causing serious injury to the hand. There was a fear that this would happen. Furthermore, the latter vending device has a problem in that it is not possible to transport a large number of products at the same time because each product case is accommodated in the bucket and transported one by one.

In view of the above-mentioned conventional problems, the purpose of the present invention is to eliminate the risk of damaging hands when taking out products, and
The purpose is to provide a vending machine that can sell a large number of products at the same time.

(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, product storage shelves are provided in a plurality of stages at predetermined intervals along the travel path of the bucket, and the storage shelves in each stage are arranged in a plurality of rows in parallel in front and behind the vending machine main body. A conveyor having a product placement surface and capable of transporting the products to the moving path side of the bucket is attached to each of the storage shelves, and the bucket is formed to have a substantially U-shaped cross section, and a side surface of the bucket is provided. A loading port corresponding to the carrying-out side of each of the storage shelves arranged in parallel is provided in the container, and a transport port to the product take-out port is provided in the front surface of the bucket, and a connecting rod is connected to the bottom plate of the bucket. The present invention is characterized in that a biasing means is attached to the chain of the elevator so as to be rotatable in the vertical direction through the connecting rod, and biasing means is provided on the connecting rod to bias the bottom plate to be positioned horizontally.

(Function) According to the present invention, the storage shelves of each stage are arranged in plural rows in parallel at the front and rear of the vending machine main body, and the bucket is formed into a substantially U-shaped cross section, and the storage shelves are arranged in parallel on the side of the bucket. Since the carrying-in port is formed opposite to the carrying-out side of each of the arranged storage shelves, it is possible to simultaneously accommodate and transport the same number of storage shelves in the bucket as there are storage shelves arranged in parallel. Furthermore, a transport port to a product outlet is provided on the front surface of the bucket, the bottom plate of the bucket is attached to the chain of the elevator via a connecting rod so as to be rotatable in the vertical direction, and the bottom plate on the connecting rod is attached to the chain of the elevator. Since a biasing means such as a spring is installed to bias the bucket so that it is positioned horizontally, when inserting your hand into the product removal port to take out the product in the bucket, the hand moves upwards into the product removal port and the hand moves toward the product removal port. Even if it is caught between the bucket and the bucket, the bucket can rotate in the vertical direction and the hand can be easily removed, without the risk of causing serious damage to the hand.

(Embodiment) FIGS. 1 to 4 show an embodiment of the present invention, in which 40 is a vertically elongated box-shaped vending machine body filled with a heat insulating material, and 41 is a door of the vending machine body 40. The product sample section 42 is located on one side of the body, and the coin slot 43 and product selection button 44 are located on the other side.
In addition, product outlet ports 45 and 46 are provided at the bottom.

50 is a back plate 40a inside the vending machine main body 40.
The elevator is installed in the vertical direction, and is composed of an endless chain 51, a bucket 52 for transporting goods having a substantially U-shaped cross section, and a connecting rod 53. Through-holes 52a are provided on both sides of the top and bottom plates of the bucket bag 52, corresponding to the top and bottom, respectively. Further, on both sides of the bucket bag 52, a loading port 54 facing the loading side of each storage shelf 60 arranged in parallel, which will be described later, is provided. are provided for each. Further, the connecting rod 53 has one end connected to the chain 51 so that its upper surface is in a horizontal state.
The other end of the bucket 52 is pivotally attached to the lower surface of the bottom plate of the bucket 52 so as to be vertically rotatable, and the bottom plate of the bucket 52 is moved onto the connecting rod 53 by a spring 56 also attached to the other end. The connecting rod 53 and the spring 56 constitute a biasing means for supporting the bucket 52 horizontally.

Reference numeral 60 denotes horizontally elongated product storage shelves that are arranged in parallel in the front and rear of the vending machine main body 40 and installed in multiple stages on both sides of the elevator 50. Products can be placed horizontally on the storage shelves 60 and products can also be loaded at the same time. A conveyor 61 that moves in the direction of the elevator 50 is attached.

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, and both are installed so that the emitted light reaches the light receiving element 81 when the bottom plate of the bucket 52 is in horizontal contact with the connecting rod 53. When the emitted light is blocked, the operation of the conveyor 61 is stopped and the bucket cart 52 is moved 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, the operation switch (not shown) of the conveyor 61a is interlocked and the conveyor 61a is operated, so the product D moves toward the bucket 52 and enters the loading port 54.
It is stored in the bucket bag 52 through the. and,
Since the product D passes over the through hole 52a at the same time as the storage, the light emitted from the light source 80 is blocked, the operation of the conveyor 61a is stopped, and the motor 10
0 rotates in the opposite direction and lowers the bucket 52. As the bucket 52 descends, one end of the bottom plate of the bucket 52 collides with the stopper 120, and the bucket 52 further rotates counterclockwise around the other end of the connecting rod 53 against the elastic force of the spring 56. As the bucket 52 rotates, the bottom plate of the bucket 52 becomes inclined and the other end abuts the chute 70. As a result, the bucket 52
The products stored in the bottom plate are delivered to the shutter 90 side through the transport port 55, and the other end of the bottom plate contacts the stop switch 71, so that the motor 10
Driving of 0 also stops. Then, the shutter 90 is opened and the product D is taken out from the product outlet 45.

Furthermore, since the storage shelves 60 are arranged in parallel in the front and back, the length of the storage shelves 60 in the width direction becomes somewhat narrow, making it difficult to place wide products on the storage shelves 60. Since a large number of products can be attached to the storage shelf 60, a wide variety of narrow products can be placed in large numbers.

Furthermore, since the loading port 54 of the bucket 52 faces each of the storage shelves 60 arranged in parallel in the front and rear, four products can be transported at the same time.

Furthermore, a transport port 55 to the product outlet 45 is provided on the front surface of the bucket bag 52, and the bottom plate of the bag bag 52 is attached to the endless chain 51 of the elevator 50 via a connecting rod 53 so as to be rotatable in the vertical direction. Since the spring 56 is attached to the connecting rod 53 to horizontally position the bottom plate, when inserting a hand into the product outlet 45 and taking out the product in the bucket bag 52, the bucket bag 52
2 moves upwards and your hand gets caught between the product removal port 45 and the bucket 52, the bucket 52 rotates in the vertical direction so that you can easily remove your hand. No major damage to the hands.

Incidentally, in the above embodiment, a vending machine was described in which storage shelves 60 were provided on both sides of the elevator 50, but the storage shelves 60 may be provided only on one side of the elevator 50. Further, in the above embodiment, the through hole 5 of the bucket 52 is
Although a vending machine has been described in which two 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 storage shelves 60 are arranged in parallel. It may also be possible to more accurately detect the storage of products transported from the storage area.

(Effect of the invention) As explained above, the present invention provides a vending machine in which an elevator is provided with a bucket for transporting products in the main body of the vending machine, and the bucket transports products to a product outlet using the bucket. A plurality of product storage shelves are provided at predetermined intervals along the travel path of the vending machine, and each of the storage shelves is provided in a plurality of rows in parallel in front and behind the vending machine main body, and each of the storage shelves is A conveyor having a product placement surface and capable of transporting the products to the moving path side of the bucket is attached, and the bucket is formed into a substantially U-shaped cross section and is arranged in parallel on the side of the bucket. A carry-in port corresponding to the carry-out side of each of the storage shelves is provided, and a transport port to the product take-out port is provided on the front surface of the bucket, and the bottom plate of the bucket is connected to the chain of the elevator in the vertical direction via a connecting rod. Since the bottom plate is rotatably attached to the connecting rod and has a biasing means for biasing the bottom plate to be positioned horizontally on the connecting rod, it is possible to simultaneously transport products as many as the number of storage shelves arranged in parallel in the front and rear. This has the advantage of improving product transport efficiency. In addition, even if the bucket moves upward and your hand gets caught between the product take-out port and the bucket when you insert your hand into the product take-out port and take out the product in the bucket, the bucket will not move upward or downward. This has the advantage that a vending machine with excellent safety can be provided, since the vending machine can be rotated in the same direction, the hand can be easily taken out, and there is no risk of causing serious damage to the hand.
