The present invention relates to a so-called spiral product storage column for storing and selling boxed frozen food.

As a product storage column of this kind of vending machine, what is described, for example in Japanese Unexamined-Japanese-Patent No. 60-144178 is known.

This commodity storage column is comprised of the box body which formed the outlet part in the bottom part, the spiral member accommodated in the box body, and rotates around a vertical axis, and the electric motor provided in the upper end of the box body.

The helical member is composed of a vertical rotating shaft having an upper end connected to the motor and a spiral spiral member coaxially installed with the vertical rotating shaft.

The product is inserted and charged in two rows, left and right, along the vertical axis of rotation and spaced apart from the lowest level by the rotation of the helical member. It is supposed to pay out sequentially.

In this case, the box body is formed with a cross-sectional dimension that can accommodate the largest number of goods to be handled, while the spiral member is the smallest of the goods so that the goods do not fall to the inside (axial side) during insertion or charging. It is formed with a diameter to match the product.

For this reason, the center of gravity of the product is at the position just above or slightly axially on the plate surface of the spiral member, and the lower end of the spiral member is pulled out in the front-rear direction with respect to the product. Inclined to fall).

On the other hand, in the largest product, since the center of gravity is located on the outer side of the plate surface of the helical member, it is inclined from side to side and falls.

For this reason, there existed the unreasonable point that the fall pattern differs with the magnitude of goods, and the attitude | position of goods becomes various in the conveyance system after falling from the column.

Therefore, if the product is to be returned in a desired proper posture, a mechanism for correcting the posture of the product is required, and a problem arises that the conveying system becomes complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a product storage column of a vending machine that can deliver a product in a constant posture regardless of the size of the product.

In order to achieve the above object, the invention of claim 1 is provided with a box having a discharge outlet of the product at the bottom and a spiral member accommodated in the box and rotating around a vertical axis, and inserted and filled in the space between the spiral members. In the commodity storage column of the automatic vending machine which rotates the spiral member in a state in which the rotation is restricted by the inner surface of the box body and is discharged from the lowest one, the lower end surface portion of the spiral member extends outward in the radial direction. It is characterized by.

In addition, the invention of claim 2 is provided with a box body having a discharge outlet of the product at the bottom thereof, and a spiral member housed in the box body and rotating around a vertical axis, and inserted and filled with a space between the spiral members on the inner surface of the box body. In a commodity storage column of a vending machine which rotates a spiral member in a state in which rotation is restricted by the rotation, and dispensing it from the lowest one, the spiral members are located on the same spiral face and coaxial with each other. It has an inner spiral member and a large diameter outer spiral member.

According to the product storage column of claim 1, the lower end surface portion of the spiral member extends outward in the radial direction, so that the rotational trajectory of the tip of the lower surface portion of the spiral member is outside the center of gravity even if the maximum product is the smallest.

For this reason, the center of gravity of the product with respect to the tip of one side of the lower end face of the helical member is out of the front and rear direction.

Therefore, the product is inclined in the front and rear direction and falls.

According to the merchandise storage column of claim 2, the outer spiral member is the same as the above because the spiral members have a small diameter inner spiral member and a large diameter outer spiral member which are coaxially located and coaxially located. Of course, even the largest product is located outside of its center of gravity.

For this reason, the center of gravity of the product with respect to the lower end of the inner and outer spiral members deviates in the front-rear direction.

Therefore, the product is inclined in the front and rear direction and falls.

EXAMPLE

Next, with reference to the accompanying drawings, a description will be given of the case where the product storage column according to the first embodiment of the present invention is applied to a vending machine for selling frozen foods in box packaging.

FIG. 1 is a cutaway side view of the product storage column and FIG. 2 is a horizontal cross-sectional view.

As shown in the drawing, the commodity storage column 1 is composed of a box 2, a spiral member 3 housed in the box 2, and a drive device 4 provided at the upper end of the box 2. It is.

The box 2 is provided with a loading door (not shown) at the front and a discharge outlet 5 is formed at the bottom.

As shown in FIG. 3, the box 2 is formed with a cross sectional dimension in which the largest product A of the handling products A can be accommodated and the second product is smaller than the maximum product A. As shown in the figure, the attachment and detachment inside the box 2 can be adjusted by the attachment 6 attached freely.

This prevents the article A from rotating together with the helical member 3 with the rotation of the helical member 3.

The helical member 3 has a vertical rotating shaft 7 and a spiral rotating member 8 and a spiral rotating member 8 which are provided coaxially with the vertical rotating shaft 7 and the vertical rotating shaft 7 having the upper end connected to the drive device 4. It consists of three upper and lower support rods 9, 9, and 9 fixed to 7).

The drive device 4 is composed of a drive motor 10 and a reducer 11, and the helical member 3 is rotated at a low speed in the direction of the arrow shown in Figs. 2 and 3 by the drive motor 10. .

On the other hand, the goods A are inserted and loaded in two rows, left and right, respectively at intervals of the helical member 8 by opening the loading door and inserting the vertical rotation shaft 7 from the front.

In this case, the goods A in the right row are loaded in a downwardly descending posture as shown in FIG. 1, and the goods A in the left row are loaded in a downwardly descending posture, although not shown.

In this state, when the helical member 8 rotates, the goods A are slowly moved while being in contact with the helical member 8 by sliding movement of the front, rear, left and right sides on the inner surface of the box 2 or the attachment 6. Going down.

When the helical member 8 is rotated 180 degrees, for example, the lowermost goods A of the right row are issued. Following the sales order, the spiral member 8 is rotated 180 degrees again. ) Is dispensed.

In this way, the goods A are dispensed one by one from the lowest one sequentially.

Here, the characteristic part of this invention is demonstrated.

As shown in FIG. 1, FIG. 2, and FIG. 3, the lower end face part 8a of the spiral member 8 of this embodiment extends outward in the radial direction so as to open outward.

That is, as shown in FIG. 2, other parts of the spiral member 8 except for the lower one-sided portion 8a have the center of gravity W of the minimum product A just above or perpendicular to the plate surface of the spiral member 8. The lower one side surface portion 8a, which is formed so as to come to a position slightly approached to the rotation shaft 7 side, as shown in FIG. 3 so that the center of gravity W of the largest product A is located inside the rotation trajectory drawn by the tip thereof. Formed.

As a result, in the minimum article A, the helical member 8 starts to rotate from the state of FIG. 2 (a), and the lower end surface portion 8a becomes the state of X in FIG. 2 (b). The center of gravity W of A) deviates from the lower end surface part 8a, and the goods A incline slightly inward.

However, since the product A inclined inward touches the vertical rotational shaft 7 and is supported there, finally, the second center in which the center of gravity W of the product A deviates rearward from the lower one side portion 8a. When it is in the state Y of (b), it inclines backward and falls.

In the maximum product A, when the helical member 8 starts to rotate from the state of FIG. 3 (a), and the lower end surface portion 8a passes through X of FIG. 2 (b) and becomes Y state. The center of gravity (W) of the goods (A) is out of the lower one side portion (8a).

Therefore, also in this case, the goods A fall inclined backward.

As described above, in the present embodiment, the product A can be inclined backward and dropped regardless of the size of the handled product A.

Therefore, the fall posture of the goods A can be made constant regardless of the size, and it becomes easy to maintain the posture of the goods A suitably at the time of conveyance of the goods A afterwards.

In addition, the lower end surface part 8a of the spiral member 8 of this embodiment may extend in a straight line in the tangential direction, or may extend in an arc shape.

Moreover, in order to stably fall the goods A, you may form wide.

4 shows a second embodiment of the present invention.

In this embodiment, the threaded member is composed of a double of the inner diameter threaded member 12 having a smaller diameter and the outer diameter spiral member 13 having a larger diameter fixed to the vertical rotation shaft 7.

The inner spiral member 12 and the outer spiral member 13 are spirals of the same pitch and the lower end thereof is disposed at the same position in the circumferential direction.

In other words, the inner and outer spiral members 12 and 13 have a shape in which the middle portion in the width direction of the spiral member is widely cut.

And the inner spiral member 12 is formed such that the center of gravity (W) of the minimum product (A) is located slightly above the plate surface or toward the vertical rotation shaft (7) as in the first embodiment and the outer spiral member (13) ) Is formed such that the center of gravity W of the largest product A is located inside the plate surface.

This results in the product A being inclined to fall backward in the minimum product A as in the first embodiment, and the rotation of the internal and external spiral members 12 and 13 also proceeds 90 degrees in the maximum product A. Since the center of gravity (W) of the () is out of the inner and outer spiral members 12, 13, the product (A) falls inclined backward.

Therefore, the case of the second embodiment also exhibits the same effects as those of the first embodiment.

As described above, according to the product storage column of the present invention, the falling posture of the product can be made constant regardless of the size, and the effect of being able to return and sell the goods in the proper posture without complicating the subsequent return system of the goods.
