Description

[Detailed Description of the Invention] The present invention relates to an elevator-type product delivery device that is suitable for application to vending machines and the like.

Generally, in this type of unloading device, the shelves are transported downward in a horizontal position on the product conveyance path in the linear downward movement area of the endless chain, and at the lower end of the product conveyance path, the shelves gradually move along the periphery of the sprocket. It has a tilting structure.

Therefore, since the above-mentioned tilting operation of the shelf board is performed slowly, for example, if the top of the shelf board is damp and a product is adsorbed to the shelf board, the product may not fall or the timing may be delayed. It had drawbacks such as being biased and not falling in a predetermined falling path, resulting in clogging.

The present invention was devised in view of the shortcomings of the conventional device, and it rotates the shelf rapidly when it reaches the end of the product conveyance path, and prevents the rapid rotation of the shelf and the front edge of the shelf. The purpose is to ensure that products that have been supported and stored with bending are dropped and transported at a predetermined timing.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a front view and a side view schematically showing the lower part of the product delivery device according to the present invention, and FIG. 3 is a perspective view of one shelf board.
In these figures, reference numeral 1 denotes a sprocket rotatably attached to one end of the drive shaft 2, and such sprockets are provided at the other end of the drive shaft 2 and at both ends of the upper driven shaft (not shown). , and endless chains 3, 3 are stretched between the upper and lower sprockets, respectively.

Reference numeral 4 denotes a side plate having bearing portions 5 for the drive shaft 2 and the driven shaft at the upper and lower ends, and these side plates are provided at both ends of both shafts, respectively.

Incidentally, this side plate 4 is fixed to, for example, the main body of the vending machine by suitable fixing means.

Reference numerals 6 and 6 designate a front guide plate installed in front of the side plate 4 so as to be approximately flush with the side plate 4 near both ends of the drive shaft 2 and the driven shaft, and leave a gap between it and the side plate 4. A notch 9 is provided at the lower end of the guide surface 8 forming the guide groove 7.
has been established.

Reference numeral 10 denotes a rear guide plate installed at the rear of the side plate 4 so as to be substantially flush with the side plate 4, similar to the guide plate 6, and a guide groove 11 is formed between it and the rear edge of the side plate 4. There is.

12 is a shelf board made of a dust pan-shaped frame,
An angle 14 bridging between mounting pieces 13, 13 protruding rearward from both rear ends of the rear vertical part.
It is horizontally attached to the endless chains 3, 3 in the left and right direction, and the angle 14 is
is pivotally supported by the mounting pieces 13, 13, so that it can swing freely.

Furthermore, there are two guide rollers located above and below on the outer surfaces of both mounting pieces 13, 13, respectively, and the inner lower guide roller _R1 is connected to the angle 1 above.
4 is pivoted on the shaft on which the mounting piece R 2 is pivoted, and the upper one R ₂ is pivoted on the outer surface of the mounting piece 13 .

These guide rollers R ₁ and R ₂ are located within the guide grooves 7 and 11 while the shelf board 12 attached to the endless chains 3 and 3 passes through the linear movement range of the endless chains 3 and 3, In particular, in the region of linear downward movement of the endless chains 3, 3 (in short, the product conveyance path), it acts to maintain the shelf board 12 in a horizontal normal position.

Note that the shelf board 12 has its front half 12b connected to the rear half 12a by a hinge 15, and only in the horizontal normal posture both the sections 12a and 12b are formed on the same plane; When the robot is in a horizontally inverted position in a straight-line upward movement region, the front half 12b is suspended by the hinge 15.

Reference numeral 16 designates a base plate for fixing the lower ends of the guide plates 6 and 10, and a chute 17 for guiding the product F to the next stage is formed at the front end of the base plate.

18 is a motor that rotates the drive shaft 2.

Since the present invention is constructed as described above, when the shelf board 12 is in the linear downward movement area of the endless chains 3, 3, in other words, in the product conveyance path, the guide rollers _R1 , _R2 are in the guide groove. Since it is located within 7, it assumes a horizontal normal posture and securely supports and stores the product F.

Then, from this horizontal normal posture, the endless chains 3, 3 move and descend to reach the end of the product conveyance path, and when the guide roller R ₂ comes off from the guide groove 7 and fits into the notch 9, the shelf plate Item 12 rotates rapidly and loses its horizontal position, causing product F to be stored.
Drop and carry out.

Also, at this time, the rotation of the shelf board 12 is controlled by the guide roller.
Since _R2 hits the regulating piece 6a provided at the edge of the notch 9, it is regulated within an appropriate range and the shelf board 12 is protected. Also, the shelf board 12 that was damp
Even if a product is stuck on the top and does not come off, when the shelf board 12 comes into contact with the chute 17 area or a part of the board 16, the front half 12b of the shelf board 12 rotates inward around the hinge part 15. Because of this movement, the product can be carried out reliably, and product jams due to timing lags in product delivery are eliminated.

Since the present invention is constructed as described above, the products can be reliably removed from the shelves.
This is an excellent idea, as there is no concern that the product will not be delivered or that the timing of delivery will be uneven.
