Abstract

PURPOSE:To surely open a door with simple constitution by converting the moving force of a commodity placing rack which comprises part of an ejector to a commodity output port to the releasing force of the door. CONSTITUTION:When a selected commodity is raised to the commodity output port 2 by moving the commodity placing rack upward, the cam roll 3g of the commodity placing rack is abutted with a rocking lever 5 on the middle way of raising, which rocks the rocking lever 5 against the force of a spring 5a. And the posture of a tray 3d is changed as converting the fast movement of the commodity placing rack 3a to a moderate opening action, and a complete releasing state can be set at the time of slipping off a delivery commodity A. In such a way, it is possible to surely release the door, and to eliminate the staying of the commodity as in a conventional device, and also, to dispense with a specific driving device though a compulsory releasing method is used.

, or the receiver is fixed on the product shelf (3a) of the elevator device (3).

FIG. 1 specifically shows the internal structure of the front door (C1). As shown in the drawing, the horizontal conveyance device (1) is a small conveyor that conveys the delivered product (A) to the side of the elevator device (3) and passes it there. The elevator device (3) has upper and lower sprockets (
3b), (3b) Wind the chain (3C) between them,
A product shelf (3a) is attached to this chain (3c). The product (A) dispensed at the bottom of the vending machine is placed at the front door (A) so that it can be easily received by the purchaser.
The product loading shelf (3a) is lifted up by the product loading/unloading shelf (3a) into the merchandise taking out port (2) provided at the top of the C8). The product (A) is reciprocated between the product take-out ports (2) based on the arrival detection of the product (A), and the tray (3d) changes its posture at the product take-out port (2) to allow the product (A) to be carried out to slide down. . Reference numerals (3e) and (3f) in the drawings represent a spring and a locking pawl for changing the posture, and the spring (3e)
e) maintains the tray (3d) in the loading position, and the locking claw (3f) resists the force of the spring (3e) when the product shelf (3a) reaches the product outlet (2). and said tray (
3d) is changed to the payout posture.

The product outlet (2) is provided with an opening/closing door (4) to prevent cold air and warm air from flowing out of the vending machine and to prevent dust from entering the machine, and the product shelf (3a) This product loading shelf (3) is on the route to the product takeout port (2).
The following structure is provided as a mechanical interlocking means for opening the opening/closing door (4) by the contact force with a). That is, a swing lever (5) whose free end enters the movement path of the product shelf (3a) and whose base end is pivoted outside the movement path, and a pivot lever (5) of the opening/closing door (4). An opening/closing operation lever (6) fixed to one end of the support shaft (4a) is provided, and a spring (5) is provided.
