Description

[Detailed description of the invention] This invention relates to an improvement of an elevator-type product shelf of a vending machine that handles bottle or can products.

First, the outline of the elevator-type product shelf mentioned above will be briefly explained with reference to FIG.

In the figure, 1 and 2 are sprockets arranged above and below, 3 is an endless chain stretched between sprockets 1 and 2,
4 is a chain, 4 is a vertically long shelf board with a cross-sectional shape of a single character, which is hung at predetermined pitch intervals along the chain 3; A pen motor drives the sprocket in the direction of the arrow so as to move it pitch by pitch, 6 is a shelf frame housing a chain drive mechanism, 7 is a shelf board posture guide provided inside the shelf frame, 8 is a product guide, and 9 are adjacent to each other. A vertical product transport path 10 is defined between the shelf frames of the columns and opened toward the front of the product shelf, and numeral 10 indicates the products placed on each shelf board 4 in the product transport path area.

When filling the shelf with products, the product 10 is inserted into the product transport path 9 from the front of the product shelf along the vertical direction of the shelf board,
As shown in the figure, it is carried and stored on each shelf board 4 that protrudes across the product transport path.

When a sales command is given from this state, the pend motor 5
Driven by , the shelf board 4 with the product 10 placed thereon descends in an elevator-like manner by l pitches, and at the point where the shelf board 4 deviates from the posture guide γ, it swings downward and the product 10 falls as shown by arrow A. It will be carried out.

By the way, as shown in FIGS. 2a and 2b, the L-shaped shelf board 4 consists of a bottom plate part 41, a side plate part 42, and a mounting base part 43 that protrudes front and rear from the upper end of the side plate part 42, and the mounting base part 43 is arranged in the front and rear. It is suspended and supported so as to be swingable between two chains 3.

Further, in the product transport path 9 area, the shelf board 4 is supported by the posture guide 7 on its back side, and its posture is controlled such that the bottom plate portion 41 protrudes into the product transport path 9.

On the other hand, as shown in FIG. 4, the shelf frame 6 has a housing structure that combines a back plate 61 which also serves as the product guide 8 shown in FIG. 1,
A drive chain mechanism consisting of a chain 2 and a chain 3 is enclosed and housed.

Further, one side of the shelf frame body 6 facing the product conveyance path 9 is open, and the bottom plate portion 41 of the shelf board 4 projects into the product conveyance path 9 through this open area 64.

In particular, the front plate 62 and the rear plate 63 of the shelf frame 6 are bent at their ends on the product conveyance path side toward the open area 64 so as to constitute a chain guide wall for the chain 3.

With the above configuration, the shelf frame body 6 as a whole has a substantially U-shaped cross section.

Therefore, in the second rotation and in the conventional product shelf shown in FIG. It is located inward from the surface of the open area connecting the board surfaces.

For this reason, as shown in FIG. 4, during product filling work, when inserting the product 10 lying on its side from the front of the product shelf into the product conveyance path 9 along the vertical direction of the shelf board 4 as shown by arrow B, the product 10
When the pushing position of the product 10 is slightly distorted, the tip of the product 10 slides along the side plate portion 42 of the shelf board 4, and in the process, the tip touches the edge of the open area of the rear plate 63 that constitutes the shelf frame 6. 6
It may hit 3a and stop midway before being pushed into the predetermined storage position while being caught there.

Moreover, if the worker does not notice this condition and leaves the storage position unadjusted, the product 10 will not follow the movement of the shelf board 4 properly and be lowered during the sales operation, and the product transport path 9 This may cause sales troubles due to product jams caused by bridges in the middle of the process.

Alternatively, when pushing the product 10 forcefully, the edge 63a
There is also a risk that the product may be damaged due to a collision.

Furthermore, since the shelf frame body 6 requires a guiding function for the chain 3, the bent portion of the rear plate 63 described above is indispensable. It will stand out.

The present invention was developed in response to a request to solve the above-mentioned problem, and its purpose is to provide a convenient storage position without getting caught in the middle even if the insertion position is inclined with respect to the conveyance path of the product shelf when filling the product. The purpose of the present invention is to obtain a product shelf that can be smoothly pushed in, and the structure of the present invention will be described in detail based on the illustrated embodiment.

3a, b> and FIG. 5, according to the present invention, the side plate portion 42 of the L-shaped shelf board 4 has a product filling guide that bulges out toward the product conveyance path 9 along its upper edge. 44 (hatched to clearly identify the parts).

The girdle guide 44 is integrally provided, for example, by a simultaneous molding method when the shelf board 4 is molded from resin or resin.

Moreover, the bulging dimension of the guide 44 is such that its end face forms an open area 640 connecting the front plate 62 and the rear plate 63 that are attached to the shelf frame 6.
Beyond the surface, it is determined to protrude slightly toward the product conveyance path 9 by a dimension d.

According to the above configuration, as clearly shown in FIG. 5, the edge 63a of the rear plate 63 is located behind the product filling guide 44 when viewed from the front of the product shelf, that is, from the product filling direction, and the end edge 63a of the rear plate 63 is located behind the product filling guide 44. During filling, the product 10 inserted in the direction of arrow B while being guided along the guide 44 touches the edge 63a midway.
It can be pushed into the old predetermined storage position shown in the figure without causing body hair.

Moreover, the product filling guide 44 can be provided extremely easily.

Like the olfactory device, this invention eliminates the problem of product filling errors in the past by simply adding a product filling guide to the shelf board without making any changes to the overall structure of the product shelf. You can save time and improve product filling efficiency.
The real benefit is the dog.
