Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a plurality of product storage shelves connected in parallel around a chain mechanism.

[Conventional technology]

FIG. 1 shows the appearance of a vending machine, in which a front door 2 of a cabinet 1 is provided with a coin slot 3, a product selection pushbutton 4, a product takeout port 5, and the like. When the front door 2 is opened, a product shelf is housed therein, and the outline of this product shelf will be explained with reference to FIG. 2.

In the figure, reference numeral 6 denotes a product storage, and the product shelves stored in the warehouse are composed of a chain mechanism 10 and a plurality of product storage shelves 2 supported around the chain mechanism 10.
0, and a carry-out mechanism 30 for carrying out the goods is installed at the bottom of this shelf. The chain mechanism 10 is located in the center of the refrigerator and has sprockets 11 and 12 arranged above and below.
A pair of endless chains 13 stretched across the upper sprocket 11 and a chain 14
Reversible chain drive motor 1 connected via
It consists of 5. A plurality of product storage shelves are individually connected and supported to the endless chain 13 along the circumference of the endless chain 13. This product storage shelf 20 is a gutter-shaped shelf container 2 with an approximately U-shaped cross section and an open outer peripheral surface and front surface.
1 and a locking shaft 22 that fits into a support shaft protruding inward from the endless chain 13, and the locking shaft 22 is attached to the back surface of the bottom wall of the shelf container 21.

The product shelf configured in this manner must be able to be attached to and detached from the endless chain 13 in order to allow the size of the shelf containers 21 to be changed.

Here, conventionally, a structure in which a shelf is detachably attached between endless chains has been used, for example.
It is known from the publication number. In this configuration, support shafts protruding inward from the endless chain are inserted into fitting holes provided at both ends of the shelf, and between one end of the shelf and the endless chain, the shelf is directed toward the endless chain on the other side. A spring is provided for biasing and fixing. To remove the shelf, resist the biasing force of the spring, move the shelf to the spring side, remove the support shaft from the fitting hole on the other side, then move the shelf in the opposite direction and remove it from the fitting hole on the spring side. Remove the support shaft. When installing a shelf, the operation is the reverse of the operation when removing it.

[The problem that the idea aims to solve]

By the way, in the above-mentioned conventional structure for attaching and detaching shelves, the shelves are attached and detached by moving them between chains, so the length of the shelves is increased by the amount of movement, so the length of product placement is shortened, and product support is reduced. becomes unstable. Also, if the biasing force of the spring is weak, there is a risk that the shelf will come off during operation, but if the biasing force of the spring is strengthened, the gap between the endless chains will be expanded, and the chain will be pressed against the guide plate for travel guidance.
The chain tends to come off the sprocket, and when the shelf is attached or detached, the shelf must be moved against the urging force of a strong spring, making it difficult to attach or detach.

Therefore, with this invention, the shelf container can be easily attached and detached, and the shelf container can have a sufficient length to stably support the product. Another object of the present invention is to provide a product shelf for a vending machine in which the chain and shelf containers do not come off accidentally.

[Means to solve the problem]

This invention consists of a chain mechanism consisting of a pair of endless chains and a chain drive motor, each of which is stretched between upper and lower sprockets in a product storage, and a chain mechanism that is arranged around the endless chain and connected between each of the pair of endless chains. A vending machine product shelf comprising a plurality of externally open product storage shelves connected and supported across the product storage shelves, wherein the product storage shelves include a gutter-shaped shelf container having a substantially U-shaped cross section; It is composed of a support shaft that has a mounting base for the shelf container and projects inwardly from the endless chain, and a locking shaft that fits, and a horizontal elongated hole is provided at the end of the bottom wall of the shelf container. The mounting base is fastened to the back surface of the bottom wall of the shelf container from the inner surface of the shelf container with a screw passing through the elongated hole.

[Effect]

According to the product shelf of this invention constructed based on the above means, when the shelf container is removed, by loosening the screws from the inner surface of the shelf container, the mounting base fixed to the back side of the shelf container by the screw can be removed. can slide relative to the shelf container, so when the screw is moved inward along the long hole in this state, the mounting base will move together with the screw, and the locking shaft of the mounting base and the support protruding from the chain will move together with the screw. The fitting with the shaft is released, and the shelf container can be removed from the chain. This operation is reversed when installing the shelf containers. Therefore, the shelf container can be easily attached and detached, and can be securely fixed to the chain. In addition, unlike conventional mounting structures, the shelf containers are not fixed with spring bias, so
There is no need to push the gap between the chains and there is no risk of the chain coming off the sprocket. Furthermore, since the attachment base is moved without moving the shelf container, there is no problem of shortening the length of the shelf due to moving the shelf between chains as in the conventional case, and the sufficient length of the shelf container can be ensured. It becomes possible to stably support the product.

〔Example〕

3 and 4 show embodiments of this invention, and the same reference numerals as in FIG. 2 indicate one or equivalent parts.

In FIG. 3 and FIG. 4, 24 is a shelf container 21.
Two elongated holes are provided at each end of the bottom wall of the bottom wall, each opening in the direction between the pair of endless chains. 25 and 26 are screws inserted into both ends of the elongated hole 24, the screw 25 is inserted into the end of the elongated hole from the center of the shelf container in the direction between the endless chains, and the screw 26 is inserted into the elongated hole end. It is inserted into the end opposite to the slot end. Reference numeral 27 denotes a substantially U-shaped mounting base disposed at both ends of the back surface of the bottom wall of the shelf container 21, and screws are installed on the bottom wall of the mounting base in accordance with the insertion positions of the screws 25 and 26, respectively. There are 4 holes each, and 2 holes on both bends.
A locking shaft 22, which is a hollow shaft, is inserted into each hole and fixed to a mounting base 27. The screws 25 and 26 pass through the long holes 24 of the shelf container 21 and are screwed into the screw holes of the mounting base 27 to fasten the mounting base 27 to the shelf container 21. Furthermore, the locking shaft 22 of the shelf container 21 is fitted with a pin-shaped support shaft 23 that projects inward from the endless chain 13, and the shelf container 21 is fixed to the endless chain 13.

In this configuration, when removing the shelf container 21 from the endless chain 13, first loosen and remove the four screws 25 from the inner surface of the bottom wall of the shelf container 21, and then loosen the four screws 26 as appropriate.
Holding 6, make a long hole 2 in the direction between the endless chains.
4, the mounting bases 27 at both ends also move, the locking shafts 22 come out of the support shafts 23 of the endless chain 13, and the shelf container 21 is easily moved.
can be removed from the endless chain 13, and when installing it, it is easy to do the reverse operation as described above.
and can be installed reliably.

Note that the screw 25 is provided to easily restrict the sliding movement of the mount, and can be omitted if the mount 27 is sufficiently tightened to the shelf container 21 with the screw 26.

[Effect of idea]

According to this invention, a product storage shelf includes a gutter-shaped shelf container having a substantially U-shaped cross section, and a fitting that has a mounting base for the shelf container and is fitted with a support shaft that projects inwardly from the endless chain. At the same time, a horizontal elongated hole is provided at the end of the bottom wall of the shelf container, and the mounting base is attached to the back surface of the bottom wall of the shelf container with a screw passing through the elongated hole from the inner surface of the shelf container. Since this is done, the following effects are achieved.

(1) The shelf container can be removed from the endless chain with a simple operation of loosening the screws and sliding the mounting base, and the shelf container can be securely fixed by tightening the screws when installing.

(2) Since the shelf container is not fixed by spring bias as in the conventional case, the space between the chains is not pushed apart and there is no risk of the chain coming off the sprocket.

(3) Since the mounting base is moved when installing and removing shelf containers, the length of the shelf will not be shortened unlike the conventional mounting structure in which shelves are moved, and sufficient length of shelf containers can be obtained to store products. It can be stably supported.
