【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a product storage column, the front surface of which is opened and a product storage port 2 is provided. Reference numeral 3 denotes a rotary unloading member for unloading products, which is rotatably arranged in the vertical direction in the product storage column 1, and is a so-called spiral in which gaps for inserting and supporting products, which will be described later, are formed at regular intervals. ing. The rotary carry-out member 3 is attached and fixed to a rotary shaft 4 arranged in the center thereof and extending in the vertical direction via an upper support rod 5a and a lower support rod 5b. Here, the lower support lot 5b normally supports the lowermost product and is on standby for sale, and also serves as a member that loses its support and sends out the product when the rotary carry-out member 3 is rotated by a sales command. The lower end of the rotary shaft 4 is rotatably supported by the tip of a support fitting 6 provided below the product storage column 1.

Now, as shown in FIGS. 1 and 3, a product, for example, a cup-shaped product 10a, 10b, 10c, such as cup-shaped ice cream or a cup ramen, is provided between the pitches of the rotary unloading member 3 described above. , 10d are evenly arranged and filled.

Here, among the products placed on the rotary unloading member 3, the right products 10a and 10b are both in a state of being inclined toward the front side, and conversely, the two left products 10c and 10d are both. It is in a state that it is inclined to the back.

In the rotary unloading member 3 in which the four commodities 10a, 10b, 10c, and 10d are evenly arranged around the periphery in this way, one merchandise is provided for each 1/4 (90 degrees) rotation thereof. It will be sent out and dropped.

A drive unit for driving the rotary shaft 4 is provided at the upper part of the product storage column 1, and has a drive motor 13 with a deceleration gear 12 and a joy shaft 14 that is rotated by transmission through the reduction gear 12. Etc. The rotary shaft 4 and the joint shaft 14 are connected by a connecting pin 15 provided at the lower end of the joint shaft 14, and the rotational force of the drive motor 13 is transmitted to the rotary transfer member 3.

Reference numeral 16 denotes a motor mounting plate to which the drive motor 13 with the reduction gear 11 is mounted and fixed by screws 17 and 17. Magnet mounting plates 18a, 18b are mounted on the joint shaft 14 with screws 19, 19, and the four magnets 21a, 21b, 21c, 21d are mounted on the magnet mounting plates 18a, 18b, which are rectangular as shown in FIG. Are installed at the corners so that they are evenly scattered in four directions.

On the other hand, the reed switch 22 which is operated by the magnets 21a, 21b, 21c, 21d is disposed in the vicinity of the mounting plates 18a, 18b so as to be supported by the motor mounting plate 16 at one place around them. Has been done.

Therefore, the magnets 21 a to 21 d rotate as the rotary carry-out member 3 rotates, and when the magnets 21 a to 21 d approach the reed switch 22, the contacts in the reed switch 22 continue to operate. Specifically, when the customer presses the selection switch and the drive motor 13 is energized, the rotary unloading member 3 rotates, and one product on the rotary unloading member 3 falls. Then, before the next second product drops, the magnet operates the reed switch 22 to cut off the power supply to the drive motor 13 to end one sales cycle.

That is, the reed switch 22 and the four magnets 21 a to 21 d that rotate are configured as a motor rotation control unit that controls the rotation stop of the drive motor 13 in order to intermittently rotate the rotation shaft 4 by 90 degrees. .

Reference numeral 24 denotes a front door that opens and closes the product storage port 2 of the product storage column 1, and curls 25 and 25 are formed on one side. The curls 25 and 25 are formed as shown in FIG. The front door 24 is rotatably supported with the curl portions 25, 25 as a fulcrum by being inserted into the support portions 26, 26 provided at the upper and lower sides of the storage column 1 to open and close the product storage port 2.

As shown in FIG. 1, a stopper 28, which is one member of the front door closing device, is attached to the front door 24 above the rear portion of the front door 24 on the side opposite to the shaft support side. On the other hand, on the product storage column 1 side, a plate member 29, which is the other member for locking the stopper 28, is attached and fixed by a screw 30.

Therefore, when the front door 24 is opened, the stopper 28 is disengaged from the leaf spring 29 and can be opened by pulling the handle portion 24c toward you. To close it, reverse the procedure.

Next, a description will be given of a configuration in which four products 10a to 10d are evenly arranged in the product storage column 1 as shown in FIG.

All the two products 10b, 10c on the inner side of the back wall 1H of the product storage column 1 which extend vertically and project inwardly and which are mounted on the rotary carry-out member 3 move to each other. A fourth holding member 31 is separately attached so as not to touch.

On the other hand, on the back surface of the front door 24, all the two front products 10 a, 1 that extend in the up-down direction so as to be opposed to the fourth holding member 31 and project on the rotary unloading member 3 A fifth holding member 32 is attached to hold 0d separately so as not to move each other. The fourth and fifth holding members 31 and 32 are formed of a metal plate or the like having a rigidity that does not damage the products 10a to 10d.

In the right side wall 1R of the product storage column 1, a third holding member 33 is provided on the front side thereof, that is, at the edge position on the open side of the product storage port 2. The third holding member 33 is sandwiched by a mounting plate 51 and attached to a support piece 55 with a screw 52.

The third holding member 33 is made of a flexible material such as resin, and when the front door 24 is opened to fill the product, the product 10 (shown by a solid line in FIG. 4) is used. (Shown) makes it possible to fill the product by bending in the pushing direction, and when the product enters (product 10 shown by the dotted line), it is elastically returned to the original state and locked so that the product does not move to the front It is supposed to be.

That is, the product 10a entering the right front position is about to fall due to the inclination of the rotary unloading member 3. The product 10a is supported by the fifth holding member 32 of the front door 24 that is closed at the time of sale, but cannot be held when the front door 24 is opened and filled. In this case, the third holding member 33 hits the product 10a as shown in FIG. 5 to prevent the product 10a once filled from falling along the inclination of the rotary unloading member 3.

Further, a first holding member 35 made of the same flexible material is attached to the center of the inner surface of the right side wall 1R of the product storage column 1 so as to extend in the vertical direction and project inward. The first holding member 35 is positioned in a recess 58a formed in the right side wall 1R, sandwiched by a mounting plate 56, and fixed by a screw 57. The first holding member 35 also bends inward due to an external force.

Therefore, as shown in FIG. 4, when the third holding member 33 is bent and the product 10 placed in the right front side of the product storage column 1 is pushed further inward, the first holding member 35 is changed to the one shown in FIG. The product can be bent as shown to fill the right side of the product storage column 1 as a product 10b shown by a dotted line.

Then, when the product 10b (shown by the dotted line) that has once been packed into the right rear position of the product storage column 1 is about to fall due to the tilt of the rotary unloading member 3 or vibration, as shown in FIG. The first holding member 35 is prevented from easily falling. Therefore, the first holding member 35 holds the products 10a and 10b at that position so as not to move.

At the center of the inner surface of the left side wall 1L of the product storage column 1, a second holding member 36 also made of a flexible material is positioned in the recess 58b and extends vertically. It is attached with screws 59 sandwiching the mounting plate 60.

Since the second holding member 36 also easily bends rearward when the product is pushed in from the front side, if the product is put in the left front side of the product storage column 1 and further pushed in, the product 10c can be filled in that position. You can

In front of the product storage column 1 on the left side, the product rides on the rotary unloading member 3 while being inclined backward, so that the product can be filled as the product 10d by simply inserting it in this position. The product 10c and the product 10d are prevented from moving by the second holding member 36.

Reference numeral 41 denotes a product selling plate, and when the product 10c is not present, the spring 42 moves the solid line position to the alternate long and two short dashes line position (41b) as shown in FIG. With the structure that the sold-out switch operates, the presence / absence of the product 10c can be detected.

With the above configuration, the selling operation will be described below.

As shown in FIG. 2, when the magnet 21 a comes closest to the reed switch 22, the drive motor 13 is de-energized and the rotary carry-out member 3 stops.

Moving to the next selling operation, energization of the drive motor 13 is started, and the rotary carry-out member 3 rotates in the direction of the arrow to carry out the product. Then, when the magnet 21b comes closest to the reed switch 22, the drive motor 13 is de-energized and stopped.

In this way, each time the rotary carry-out member 3 rotates 90 degrees, one product 10 is dropped. However, at this time, since the rotary carry-out member 3 is inclined, for example, the product 10a is sold, and when the product at this position disappears, the product 10b in the back tries to move to the position of the product 10a. At this time, the movement is prevented by the above-mentioned first holding member 35.

The products are sold, and finally four products remain on the rotary unloading member 3. First, as shown in FIG. 8, when the product 10a shown by the dotted line is sold, the product 10a disappears, and the product 10b in the back of the product 10a is inclined. Tries to slide to the position of the product 10a, but at this time, the product 10b is locked by the first holding member 35 which bends in the product pushing direction but does not move in the opposite direction, and prevents the fall. To be done.

After that, when the product 10b is sent out, and then the product 10c is sent out, that is, if the product 10c indicated by the dotted line is sent out as shown in FIG. 9, then the product 10d is delivered to the product delivery member. 3 rolls over and tries to drop onto the product 10c. At this time, the second product holding member 36 is bent inward by a strong external force such as pushing the product, but is not deformed by the weight of the product itself. In this case as well, the second holding member 36 sufficiently prevents the product 10d from falling. To do.

In this way, at the time of selling the product, it is possible to reliably prevent the inconvenient movement of the product to another accommodation position in the column.

As a result, the product storage device has a high product storage efficiency and can be easily filled with products.

[0042]

[Effect of device]

 As described above, the product storage device of the present invention can store products in four directions around the rotary unloading member, so that the storage efficiency can be greatly improved.

The product storage structure is also a simple structure that simply has a holding member that projects inward of the product storage column so as to hold the product at the storage position, and can be provided at low cost.

Since the predetermined holding member is made of a flexible material so as not to hinder the filling of the product, the work for storing the product can be facilitated.
