DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method in which goods stored in a rack arranged in a row in front and rear are sequentially carried forward from the front row of goods in accordance with a sales command, and sent out to a goods outlet via an elevator mechanism. The present invention relates to a structure of a bend rack applied to a vending machine.

[0002]

2. Description of the Related Art As vending machines mentioned above, bend racks for storing products arranged in a row in front and rear for each column in a cabinet of a cabinet are arranged in upper and lower rows, left and right rows, and stored in a horizontal posture. There is known a method in which a product carried out of a specified rack is transferred to a transport shelf of an elevator mechanism disposed in front of the rack, and the elevator mechanism is lowered to deliver the product to a product outlet. Also recently,
A vending machine with a transparent door and an internal door has been commercialized so that the brand of the product stored in the rack inside the machine and the product unloading operation can be seen from the front outside the machine. ing.

Further, as a bend rack mounted on such a vending machine, a pusher arranged in an upright posture on the bottom side of a drawer type rack case having a trough shape (gutter shape) is carried out using a spiral spring. And a bend mechanism that cuts out stored products one by one from the front row at the carry-out end (front end) of the rack case. Product receiving plate) and a swinging cam plate (second product receiving plate) protruding and retracting from the bottom surface of the rack case, and operating the bend mechanism by a motor drive based on a sales command to move the products one by one forward. A configuration adapted to be carried out is known, for example, from JP-A-9-62923.

[0004] In a vending machine equipped with the bend rack having the above-mentioned structure, the opening / closing gate plate (first product receiving plate) is closed during standby for sales, and the stored products arranged in a line in front and rear are pushed by a spiral spring. As a result, the products which are pressed from behind to the front opening / closing gate plate, and which are arranged in the front row, are on standby on the tilt cam plate (second product receiving plate). Here, when a sales command is given, the gate plate, which has received the front row products by the motor drive, retreats to the side from the front of the passage, and the swing cam, which has loaded the front row products, is in the forward tilted posture. Swings and protrudes into the passage. As a result, the second and subsequent products are stopped by the tilt cam and remain at the storage position, and the rear end of the front row product is lifted by the swing cam plate, and slides down the inclined surface of the cam plate while tilting forward. To be transported forward, and dropped on a transport shelf of an elevator mechanism located at a standby position therebelow to be transferred. Thereafter, the elevator mechanism descends, and discharges the product to the product outlet at the lowest point. Further, after the product is carried out, the gate plate is opened and the swing cam plate is returned to the horizontal posture. As a result, the restraint of the second and subsequent products is released, and the product is pushed by the pusher, advances by one pitch, and returns to the standby state for sale.

[0005]

The vending machine equipped with the bend rack having the above-mentioned structure has the following problems to be solved. (1) Products cut out from the rack case of the bend rack and conveyed forward slide on the tilting cam plate and fall down to the forward leaning posture, and land on the shelf of the elevator mechanism while being moved in the forward leaning posture. Will be posted. In this case, there is almost no problem if the product is short and short, and if the product is long and large, such as a plastic bottle or a large-capacity paper-packed product, the product carried out of the rack is used. Falls forward, lands on the shelf of the elevator mechanism, and is conveyed down toward the product outlet with this falling posture.

[0006] For this reason, unless a depth space equal to or greater than the length of the product is secured in the elevator descending path between the front end of the rack case and the inner door in front of the inside of the cabinet of the cabinet, the cabinet is received by the elevator mechanism. The product may lean against the inner door and be rubbed against the door surface, or in the worst case, the product may be bridged between the transport shelf of the elevator mechanism and the inner door, causing the product to be jammed. is there. In addition, with a vending machine of the internal see-through type, in which the outside door and the heat-insulating inner door are made of a transparent door so that the inside of the machine can be seen from the front, the situation where the product is sent to the product exit with the product turned over at the time of sale can be observed as it is. It gives customers a sense of discomfort and distrust.

Further, if a sufficient depth space is provided in the descending path of the elevator in order to avoid a transportation trouble due to the interference between the product and the inner door, the depth dimension of the entire vending machine increases. Or, conversely, the depth of the product storage space is limited, and the product storage efficiency decreases,
The number of goods accommodated in vending machines decreases. (2) The spiral spring, which is used as a drive spring for a pusher that pushes the products stored in the front and rear rows and stored in the rack case from the back toward the unloading end, has a large amount of bending and load stress on the spring length. Fatigue life is short,
It is difficult to stably keep the product unloading operation for a long period of time.

The present invention has been made in view of the above points, and a first object of the present invention is to maintain a product in an upright posture from a rack case to an elevator mechanism in order to increase the product accommodation efficiency of a vending machine. A second object of the present invention is to improve the bend mechanism so that the goods can be carried out, and to improve the reliability of the goods carrying-out operation by improving the spring-driven carrying mechanism for sending the goods stored in the rack to the carry-out end thereof. It is an object of the present invention to provide a bend rack which has improved handleability in terms of replenishment and the like, and which is particularly suitable for a vending machine of a see-through type inside a refrigerator in which the inside of the machine can be seen by using a front door as a see-through door.
