Abstract

PURPOSE:To carry a commodity within a short time by forming a receiving part for receiving a commodity on one end and forming a ladle-like rotational arm rotatably supported in a case on the other end. CONSTITUTION:The receiving part 19 for receiving a commodity sent from a commodity storage device 17 through a sending port 16 is formed on one end and the ladle-like rotational arm 20 rotatably supported in the case and a driving part 25 for rotating the rotational arm 20 are formed on the other end. When the arm 20 is rotated by the driving part 25, the receiving part 19 can move while tracing a locus passing the sending part 16 and a take-out port 4, so that the commodity received on the receiving part 19 can directly be carried from the sending port 16 to the take-out port 4 without transferring the commodity on the way of movement. Consequently, the commodity carried from the commodity storage device through the sending port can be carried to the take-out port within a short time.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a case in which a product is stored inside and a product storage device having a delivery port is provided with an outlet opening on the front side. The present invention relates to a product transport device for a vending machine that transports products sent from a product storage device to a takeout port through a delivery port each time the product is sold.

[Conventional technology]

A vending machine that sells products stored inside is equipped with a product storage device that stores the products in its case and delivers them one by one each time they are sold. The product is delivered from the product storage device through the product storage device. The delivered product is conveyed into a take-out opening formed in the front part of the case and opened at the front, and the customer puts the delivered goods into the take-out opening. Most of the product storage devices of this type of vending machine are of the so-called gravity drop type, in which the products stored inside are dropped one by one using gravity, and the products are sent out from a delivery port formed at the bottom end. The outlet is located at the bottom of the. If the product is to be further conveyed from the delivery port to take-out point 0 using gravity, the delivery port must be provided at a position further below the delivery port where the product cannot be delivered without bending down. In order to transport the products from the product storage device through the delivery port to the takeout port, which is located at a position where the products can be stored without bending down, a motorized product conveyance device is required, and this type of automatic vending Conventional examples of the machine are shown in Figures 3 and 4. Figure 3 is a front view showing the appearance of a conventional vending machine, and Figure 4 shows the internal structure of the conventional vending machine, including the product conveyance device. 9 is a perspective view seen from the front right side with the door open. 9 In FIGS. 3 and 4, 1 is a case, and one end of the door 2 that covers the front opening of this case 1 is rotatable. Supported by case 1. On the front side of the door 2, there is formed an outlet 4 which opens toward the right of the center and takes out the purchased products 3, and from the top there is an advertising exhibition room 5 where the products for sale are advertised and displayed. Select product 3 Press product selection
6. Input lower for inserting coins, return lever for returning inserted coins8. A return port 9 for returning change is provided. Further, at the lower part of the back side of the door 2, there is a belt conveyor 11 equipped with an endless belt 10 that is driven by a drive device (not shown) and runs in the horizontal direction, and a belt conveyor 11 equipped with an endless belt 10 which is driven by a drive device (not shown) and which is located on the left side when viewed from the back side of the belt conveyor 11 and has an outlet 4. A product conveying device 14 is constructed by disposing a conveyor 13 to a bucket 1 provided with a bucket 1-12 which is driven by a drive device (not shown) and travels in a vertical direction on the lower side. On the other hand, a product storage device 17 is installed in the case 1 for storing therein the product 3 inputted through an input port 15 formed at the upper end and delivered from the output port 16 formed at the lower end. The product 3 sent out from the product storage device 17 through the delivery port 16 is conveyed on the belt 10, and when it reaches the left end of the belt conveyor 11 when viewed from the back, it is transferred into the packet 12 and taken up above. It is transported to exit 4 and taken out by the customer.

[Problem to be solved by the invention]

However, since the product conveyance device of such a vending machine is a two-stage conveyor in the horizontal and vertical directions, a detection device is required to detect and confirm the presence, position, etc. of the product as the product is transferred. Moreover, there are problems in that the structure is complicated, the time required for transportation is long, and the cost is high.

SUMMARY OF THE INVENTION An object of the present invention is to provide a product conveyance device for a vending machine that is simple in structure and inexpensive, and can transport products discharged from a product storage device through a delivery port to the port in a short time.

[Means to solve the problem]

In order to solve the above problems, according to the present invention, a product storage device that has a delivery port and stores products inside is installed in a case in which a takeout port that opens at the front is formed. In a product conveyance device of a vending machine that transports the product sent out from the product storage device through the delivery port into the takeout port each time it is sold, one end is formed with a receiving portion for receiving the product, and the other end is formed in the case. The device includes a ladle-shaped rotating arm that is rotatably supported by the user, and a drive unit that rotationally drives the rotating arm.

[Effect]

This invention includes a ladle-shaped rotating arm that has one end formed with a receiving portion for receiving the product sent out from the product storage device through the delivery port, and the other end of which is rotatably supported within a case; Since it is equipped with a drive part that is dynamically driven, by rotating the rotating arm by the drive part', the receiving part can move along a trajectory passing through the delivery port and the take-out port, and the product can be moved while it is being moved. The products received in the receiving section can be directly transported from the sending port to the unloading port without having to be transferred.
