[Detailed description of the invention] (a) Industrial application field The present invention relates to a product conveyance shelf device for a vending machine.

(b) Conventional technology Conventionally, as a product vending device for a vending machine that is less affected by the shape or size of the product to be sold, an endless conveyor chain is built horizontally within the base and installed internally. , an automatic system in which a large number of elongated product placement members are arranged in parallel on the conveyance chain, and the product is placed on the product placement member rotatably positioned above the base body and transported to the product takeout port side. A product transport shelf device for a vending machine is known, and is disclosed, for example, in Japanese Utility Model Application Publication No. 116586/1986. and,
As shown in FIG.
A, 30B are formed perpendicularly to the longitudinal direction, and both ends 30A, 30 of the product placement member 30 are formed at right angles to the longitudinal direction.
A large number of B are arranged in parallel so that they are located in a straight line in the moving direction indicated by the arrows.

(c) Problems to be solved by the invention Due to its structure, the product transport shelf device with this configuration has the following problems:
There is an advantage that products can be stored and transported without being affected by the shape or size of the products. Therefore, for this purpose, products of various shapes are stored and transported, and for example, as shown in FIGS. BACKGROUND OF THE INVENTION Recently, beverage product containers have come in an extremely wide variety of shapes.

However, a product shaped like the above-mentioned product A tends to become unstable when placed and stored on the product placement member 30, and due to vibrations etc. when the product placement member 30 is moved, as shown in FIG. Product A as shown in Figure 10
A part of the product mounting member 30 often comes off from the end 30B and comes into contact with the upper surface of the base 31. When the product placement member 30 moves while a part of the product A is in contact with the upper surface of the base 31, only the bottom A1 of the product A is moved in the direction of the arrow as shown in FIG. As a result, the product is rotated diagonally, which has a negative impact on product transportation and causes fraudulent product sales or product jams.

In view of this, the present invention provides a device that prevents a part of the product from coming off the end of the product placement member as much as possible, and also allows the product to be transported reliably even if it comes off.

(d) Means for Solving the Problems The present invention includes an endless conveyance chain built horizontally inside the base, a large number of elongated product placement members arranged in parallel on the conveyance chain, and A product conveyance shelf device for a vending machine, in which products having different thicknesses at both ends are placed sideways on the product placement member which is rotated upward and transported to the product takeout port side. In the above, the product placement member is provided with a notch cut out diagonally toward the rear at the end thereof,
A recess opening to the side is formed between the end portions of the product placement members arranged in parallel on the rear side, and the end portions of the placed products fall into the recess and the base body Even if the product comes into contact with the recess, the end of the product that has fallen into the recess is caught by the end of the product placement member on the rear side, and the product is pressed and conveyed to the front side, which is the product removal port. This is what I did.

(e) Effect The present invention having such a configuration is applicable when the end of a product placed on the product placement member in a sideways position and whose ends have different thicknesses moves to the end of the product placement member. , the end of the product will fall into the recess and come into contact with the base, but the end of the product that has fallen into the recess will come into contact with the front end of the product placement member arranged in parallel on the rear side. The product is pressed and conveyed toward the front, which is the product outlet side.

(f) Embodiment The drawing shows an embodiment of the present invention. 1 is a vending machine main body in which a large number of product conveyance shelf devices 2 are arranged vertically and horizontally, and a door (not shown) is provided in the front. It is designed so that it can be opened and closed. This door is provided with a coin slot, a product selection button, a product takeout port, etc. (not shown) necessary for a vending machine. Further, the product transport shelf device 2 is installed substantially horizontally in the left and right direction with a predetermined interval provided vertically within the main body 1, and between the product transport shelf devices 2, 2 arranged side by side on the left and right, there is a An elevator-type product conveyance device 4 is provided to move the product receiving member 3 in the vertical direction. When a product is selected by the customer, the product transport device 4 moves the product receiving member 3 in accordance with the position of the product transport shelf device 2 that stores the selected product, and moves the product receiving member 3 from the product transport shelf device 2 to the product transport shelf device 2. When a product is received, the product receiving member 3 is lowered to a position corresponding to the product outlet (not shown), so that the product can be taken out from the product outlet.

As shown in the front cross-sectional view of FIG. 1 and the perspective view of FIG. 2, the product conveyance shelf device 2 includes a shaft 10 having a pair of left and right sprockets 8, 9 at the front and rear between side plates 6, 7 as a base body 5. , 11 are rotatably installed, and one shaft 10 is connected to a drive motor 13 via a speed reduction mechanism 12. Endless conveyor chains 14 and 15 are stretched between the sprockets 8 and 8 and between the sprockets 9 and 9 of the shafts 10 and 11, respectively. This pair of conveyance chains 14,
15 are provided with a large number of pins 16 that protrude from each other, and between the pins 16 of the conveyance chain 14 and the pins 16 of the conveyance chain 15 that face each other, a long and narrow product is placed. A large number of members 17 are detachably attached and arranged side by side with slight predetermined intervals.

As shown in FIG. 3, this elongated product placement member 17 has an upper surface 17A formed in a substantially mountain-shaped cross section that is inclined downward from the center in the front-rear direction, and a lower surface 17B.
At both ends there are mounting holes 18 into which the pin 16 can be inserted and removed.
are provided for each. Then, the product placement member 1
7 is made of, for example, polypropylene to have elasticity, and by utilizing this elasticity, it can be freely attached and detached between opposing pins 16, 16, as shown in FIG. In addition, as shown in FIGS. 2 and 3, both ends of the product placement member 17 are provided with notches 19 that are diagonally cut toward the rear, and the front and rear product placement members 17 are arranged side by side. A recess 20 opening laterally in a substantially V-shape is formed between the ends of the recess 17 . Therefore, for example, the product placement member 17
When the product placement member 1 is moved, the vibration etc. may cause the product placement member 1 to
When a product A placed on the product mounting member 17 with different thicknesses at both ends moves to the end of the product placement member 17 and tries to come off from this end, the product A is As shown in the figure, a part of the head A2 is dropped into the recess 20. Therefore, the head A
2 comes into contact with the base body 5, and the frictional resistance caused by this contact suppresses outward movement due to vibration or the like. Then, the head A2 that has fallen into the recess 20 is brought into contact with the front part of the end of the product placement member 17, which is arranged parallel to the rear with its rear part, and is pressed and conveyed forward.

On the other hand, when the product placement member 17 is rotated to the upper surface of the base 5, the lower surface 17B is supported in contact with the support members 21 whose both ends are fixed to the side plates 6 and 7.
When a product is placed and stored on the product placement member 17, it is prevented from deforming due to the weight of the product. That is, the support member 21 is provided between the pair of conveyance chains 14 and 15, and comes into contact with the lower surface of the product placement member 17 that is rotatably positioned on the upper surface of the base 5 to support the product placement member 17 substantially horizontally. I'm starting to do that.

Further, guide portions 22 are provided at the upper and lower portions of the base body 5, respectively, extending from the outside to below both ends of the product placement member 17 at the upper and lower positions of the respective conveyance chains 14 and 15. That is, as shown in FIG. 1, the upper ends of the side plates 6 and 7 serving as the base body 5 are respectively bent inwardly so that the transport chains 14 and 15 and the lower end of the product placement member 17 located at the upper part thereof are connected to each other. The guide portion 22 as the upper surface of the base body 5 extending between
A guide portion 22 is provided at the lower end of the side plate 7 and is bent to extend below the end of the product placement member 17 located at the lower part. A guide section 22 is provided which is removably attached with a screw 23 so as to extend below the end of the product placement member 17, and each guide section 22 covers each conveyance chain 14, 15 from the outside, and also covers the base body. The guide portion 22 provided at the bottom of the product support member 17 supports the product placement member 17 located below. The guide section 22 removably provided at the lower end of the side plate 6 can be used to guide the product placement member 17 and its elasticity as shown in FIG. The mounting holes 18, 18 can be inserted into and removed from the opposing pins 16, 16 while being curved. Further, in this embodiment, the guide portion 22 provided at the lower end of the side plate 6 is configured to be detachable, but the same effect can be obtained even if any of the guide portions 22 is made detachable.

24 is a guide member provided on the upper part of the side plate 7;
It forms the upper surface of the base body 5 and prevents the product A from moving significantly to the side.

In the product transport shelf device 2 having such a configuration, when a product is selected by a customer and the product receiving member 3 is positioned corresponding to the product transport shelf device 2 that stores the selected product, a transport command is sent to the drive motor 13. , the drive motor 13 rotates the conveyance chains 14 and 15 to move the product placement member 17 toward the product receiving member 3, which is the product removal port side. When it is detected that the first product on the product placement member 17 has been delivered to the product receiving member 3, the drive motor 13 is stopped and the product receiving member 3 is moved by the product conveying device 4 as shown in the figure. The product is transported to a position corresponding to the product outlet where the product is not stored.

On the other hand, even if the product A on the product placement member 17 tries to come off the end of the product placement member 17 when the product placement member 17 moves, the product A will be locked in the recess 20. There is no possibility that the product A will be conveyed in a crooked manner, and that the product A will come loose and cause a jam, or that it will not be sent erroneously.

In addition, since the product placement member 17 has elasticity, each conveyance chain 14, 15 is strongly attached between the sprockets 8, 8 and between the sprockets 9, 9 before removing or attaching one guide portion. Even after tensioned assembly, the opposing pin 1
It can be attached and detached between 6 and 16 very easily.

(g) Effects of the invention As described above, the present invention is configured such that a recess opening to the side is formed between the ends of the product placement members arranged side by side, so that a part of the product is placed in the product placement member. If the product is about to come off the edge of the product, a part of the product is inserted into the recess and is locked in the recess and transported, so that the product does not rotate during transportation. This prevents product jams and mis-delivery of products.
