[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a product transfer device for a vending machine having a product outlet at the top.

[0002]

[Prior Art]

 In recent years, there has been proposed a vending machine with a product outlet on the top so that customers can easily take out the sold product in a natural posture while standing without having to bend over. ing.

In this case, the structure of the merchandise sales mechanism is such that the merchandise delivered from the merchandise storage section is placed on a laterally-moving conveyor provided in the lower part of the vending machine, as disclosed in Japanese Utility Model Publication No. 1-147481. The product is then moved laterally, and then at its transverse feed end, it is delivered to an elevator arranged vertically, which drives the elevator to raise the product and conveys it to the upper product outlet.

As described above, the conventional product transfer device has a horizontal transfer mechanism such as a belt conveyor for laterally moving the product at the lower part, and an elevator or the like for transferring the product to the upper product outlet at one end side. The transport mechanisms were arranged respectively.

[Problems to be solved by the device]

However, since such a conventional product transport device has two transport mechanisms, the mechanism is complicated, the size of the device is increased, and the cost is increased. Since the mechanism is used, when the product is transferred from the horizontal transfer mechanism to the vertical transfer mechanism, it may happen that the product is not delivered well, and the product does not come out of the outlet and the customer receives the product. There is also the problem of unreliability in sales operations, which cannot be achieved.

[0006] Furthermore, there is a drawback in that it takes a long time to sell the products because the two product transport mechanisms are operated during continuous purchase of the products.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a product transfer device for a vending machine which is mechanically simple, can shorten the transfer time of products, and is relatively inexpensive. To aim.

[0008]

[Means for Solving the Problems]

 The present invention is a vending machine in which the product from the product storage column is sent to the lower part of the front part of the main body and is then transported to the upper product outlet, in the forward / reverse drive motor and in conjunction with this motor. Between the rotating shafts arranged vertically, a pair of upper and lower interlocking sprocket fixed to this shaft, the interlocking interlocking chains stretched between the interlocking sprockets and moving vertically, and between these interlocking chains. The product is installed horizontally, contacts the product from the product outlet at the bottom of the main body, contacts the lift plate, rises diagonally as the lift plate moves up and down, and skids on the lift plate. It is provided with a lateral product transfer plate that laterally moves to the product outlet position.

[0009]

[Action]

 When a product is sent out in response to a sales command and rides on the lifting plate, the motor drives and the interlocking chain that horizontally attaches the lifting plate is rotationally driven to raise the lifting plate. Then, the elevating plate comes into contact with the product lateral transfer plate and exerts a force to move the product lateral transfer plate laterally. As a result, the product lateral transfer plate slides on the lifting plate and conveys the product to the product take-out position.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of a vending machine equipped with the product transport device of the present invention, FIG. 2 is a side sectional view thereof, and FIG. 3 is an overall perspective view of the product transport device of the present invention.

In FIGS. 1 and 2, 1 is a main body of a vending machine, 2 is a product storage room surrounded by a heat insulating wall 2 a, and a plurality of serpentine-type product storage columns 3 are arranged in the front and rear thereof. In addition, a plurality of these product storage columns 3 are arranged side by side in the left-right direction when viewed from the front direction of the main body 1. A front opening of the product storage chamber 2 is closed by a heat insulating door 4 in the storage, and a plurality of product outlets 5 corresponding to the product storage column 3 are formed side by side in the horizontal direction on the heat insulating door 4 in the storage. In addition, each product delivery port 5 is provided with a heat-insulating sales door 6 which is pivotally supported at its upper end and which is normally in a closed state, and which is opened and rotated forward by the product M which is discharged and dropped at the time of sale. ing. Below each of the product storage columns 3, a product delivery device 7 that operates based on a sales command is provided to deliver the products M one by one. The delivered product M slides down the product drop chute 8 and exits from the product discharge port 5.

Reference numeral 9 denotes a front door that is provided on the front surface of the main body 1 so as to be openable and closable, and is located outside the in-compartment heat insulating door 4. The front door 9 is provided with a product outlet 10 at the upper side thereof, and at the same time, receives the product M delivered from the product outlet 5 and lifts and ejects the product M to the product outlet 10. Is provided inside.

The merchandise carrying device 12 is provided with sprocket wheels 15, 15, 16 and 16 that rotate in an interlocking manner, respectively, and interlocking chains 17 and 18 that are arranged opposite to each other on both sides, and the interlocking chain chains. An elevating plate 19 for horizontally receiving goods, which is horizontally installed between 17 and 18, is provided in contact with the ascending / descending plate 19, and an oblique guide groove 20 is provided so that the vertical movement of the elevating plate 19 transfers the product M laterally. A horizontal product transfer plate 21 movable along (a pair on both sides), a pair of upper and lower shafts 22, 23 for mounting and fixing the sprockets 15, 15, 16, 16 and one shaft 23 are rotationally driven. It is composed of a motor 24 that can be driven in the forward and reverse directions and its power transmission belt 25.

To further explain the product transporting device 12 with reference to FIG. 3, the lifting plate 19 is horizontally mounted and supported by the supporting members 26, 26 mounted on a part of the interlocking chains 17, 18. Then, until the product M is delivered, the product M stays in a lower position as shown in the chain double-dashed line and waits for a product to be received.

On the other hand, the lateral product transfer plate 21 fits and supports guide protrusions 27 (the other rear guide protrusion is not shown) protruding to both sides in the guide groove 20. The lateral product transfer plate 21 is also normally lowered by its own weight to the lower left end of the guide groove 20 as shown in the two-dot chain diagram.

Here, when the elevating plate 19 rises, it comes into contact with the lateral product transfer plate 21. Then, the ascending force of the elevating plate 19 causes a force to move the product lateral transfer plate 21 obliquely upward along the guide groove 20. As a result, the product lateral transfer plate 21 slides up on the elevating plate 19 and ascends, pushing the product M toward the product outlet 10.

The product transfer device 12 is housed in a device storage box 28 so that the product M does not drop on the front and rear wall surfaces thereof even when the elevating plate 19 is lifted. Reference numeral 29 indicates a speed reducer. Further, 30 is a drive pulley fixed to the shaft 23, around which the power transmission belt 25 is hung.

Next, a product transport operation by the product transport device 12 configured as described above will be described.

When the product sending device 7 is actuated in response to the sales command and the product M is sent out by the product sending port 5 and gets on the lift plate 19 (FIG. 4 (a)), the motor 24 is rotated in the forward direction and the interlocked spreader is operated. By rotating the rackets 15, 15, 16 and 16, the interlocking chains 17 and 18 are rotated in the direction of arrow a in FIG. Therefore, the lift plate 19 begins to rise. Then, the lift plate 19 contacts the bottom surface of the product lateral transfer plate 21 (FIG. 4B).

As the lift plate 19 is further lifted, a lateral moving force is exerted on the product lateral transfer plate 21, and the power is moved diagonally upward along the guide groove 20 while sliding horizontally on the lift plate 19. Be gone. As a result, the product lateral transfer plate 21 transfers the product M to the right (FIG. 4 (c)). Finally, when the horizontal product transfer plate 21 reaches the upper end position of the guide groove 20, the commercial product M is laterally moved to the position of the commercial product outlet 10 and is delivered to the commercial product outlet 10. At this point, the motor 24 is stopped.

When the product M is taken out by the customer, the motor 24 rotates in the reverse direction, and as the elevator plate 19 descends, the product lateral transfer plate 21 also returns, returning to the state of FIG. 4A.

By repeating the above series of operations, the product M is lifted and discharged to the product outlet 10. In addition, it is more preferable to provide a rotatable roller or the like on the surface of the lateral product transfer plate 21 in contact with the elevating plate 19 in order to reduce frictional resistance.
