DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise unloading device for a vending machine which leads out a merchandise carried out of a merchandise storage unit provided with a merchandise payout device to a take-out port via a chute.

[0002]

2. Description of the Related Art In a conventional merchandise unloading device of a vending machine, a merchandise storing section has a large space in accordance with an increase in the number of articles. Further, in general, the product carried out of the product storage section is guided down to the take-out port by sliding down or rolling on a chute inclined between the product storage section and the take-out port. Need more head between outlets.

For these reasons, the outlet of a conventional vending machine is generally provided at a low position.
Therefore, when the product purchaser receives the product, the take-out port is located at a low position, so that it is necessary to perform operations such as bending down and bending the waist, and it has been desired to improve the product take-out property.

Further, some vending machines have a mechanism for transporting the delivered products to a take-out port provided at an arbitrary position by providing a lift-up mechanism or the like. . However, the time required for the product to be unloaded to the outlet after the product is unloaded is
It takes about three times more than a general vending machine without a lift-up mechanism, and the cost of mounting the lift-up mechanism is inevitable.

[0005] Therefore, without using these lift-up mechanisms or the like, the commodities carried out of the merchandise storage section are moved down or down on a chute inclinedly arranged between the merchandise storage section and the take-out port. As a method of moving the take-out port upward in a general vending machine product take-out device that guides to the take-out port, the inclination angle of the chute is made gentle, and the drop between the take-out port and the lower end of the product storage section is reduced. It is possible.

[0006] As a conventional product unloading device of a vending machine, there is one disclosed in Japanese Patent Application Laid-Open No. 5-28350.

Hereinafter, the above-described conventional product unloading device of a vending machine will be described with reference to the drawings.

FIG. 9 is a side sectional view of a conventional product unloading device of a vending machine. In FIG. 9, the merchandise is unloaded from the merchandise storage unit 3 between the merchandise storage unit 3 suspended on the inner ceiling of the vending machine 1 and a plurality of product storage units 3 arranged in the lateral direction and an outlet 4 provided at the lower front part of the vending machine 1. A chute 6 is provided so as to be inclined so that the placed product 5 slides down or rolls.

A motor 22 is supported on the back of the chute 6, and an eccentric plate 23 is attached to the output shaft of the motor 22. The motor 22 and the eccentric plate 2
3 forms a vibrating device that applies vibration to the chute 6, and the chute 6 vibrates due to an impact that the outer peripheral surface of the long diameter portion of the eccentric plate 23 that is rotationally driven by the motor 22 intermittently collides with the chute 6.

When the commodity 5 is dropped and carried out of the commodity storage section 3, the motor 22 is operated, whereby the eccentric plate 23 is rotated. Due to this rotation, the outer peripheral surface of the long diameter portion of the eccentric plate 23 intermittently hits the rear surface of the chute 6 to vibrate the chute 6. Since the product 5 that has fallen on the chute 6 due to this vibration is given a trigger to slide down or roll on the chute 6, the inclination angle of the chute 6 can be reduced.

[0011]

However, in the conventional vending machine product unloading device, a vibrating device must be formed, so that a space for mounting the vibrating device is secured, and the ambient temperature during the operation of the vibrating device is increased. There are disadvantages such as ensuring reliability under bad conditions such as humidity and humidity and increasing costs.

The present invention solves the conventional problem. Since the angle of inclination of the chute can be reduced without providing a special device, the outlet for taking out the product can be provided above, and the purchaser of the product can purchase the product. Bend your hips when you receive the product,
It is possible to alleviate crouching and other actions, thereby improving the product take-out property.
