DETAILED DESCRIPTION OF THE INVENTION (A) Industrial application field The present invention relates to a product control device for a product storage shelf.

(B) Conventional technology Conventionally, a control member for preventing a product from being loaded due to a non-rollable posture of a product to be loaded is provided in a product loading port of a product transport path for rotatably storing a cylindrical product. Are known, for example, as disclosed in Japanese Utility Model Laid-Open No. 63-12279.

In this conventional technique, a control member is provided at the bottom of a product insertion port so as to be able to protrude and retract into a product transport path so as to be orthogonal to the rolling direction of the product, and urges the control member to protrude into the product transport path. A spring is provided, and when a product in a rollable position is pressed and loaded, the product is loaded over the control member, and a product in a non-rollable position is locked by the control member.

(C) Problems to be Solved by the Invention Such a conventional technique has a problem that it is impossible to reliably prevent the introduction of a product having a non-rollable posture.

In other words, this type of product storage shelf is formed so as to be able to store a plurality of types of cylindrical products having different sizes, so that a maximum diameter product that stores the size of the product conveyance path can be inserted. The product storage shelves have unique characteristics.

Therefore, since the vertical size of the product insertion port is formed corresponding to the product with a large diameter, the dimensional allowance is large when introducing a product with a small diameter, and even if the product is placed in a non-rollable posture, it can get over the control member. Therefore, there is a risk of entering the product transport path.

In view of the above, the present invention provides a product storage shelf input product control device that can reliably prevent entry of products that cannot be rolled, even if the products have different diameters due to a simple configuration. It is.

(D) Means for Solving the Problems The present invention relates to a product storage shelf provided with a product transport path for rotatably storing a cylindrical product to be input from a product input port, and has two side walls in the product input port. And a pair of elongated holes provided extending in the up and down direction, and both ends are inserted and locked between the elongated holes so as to be movable up and down, and to lock a product put into a non-rollable position. Equipped with a regulating shaft that prevents entry into the product transport path and moves up and down to allow entry of the product when pressed against the outer peripheral surface of the product placed in a rollable position, and is pressed by the input product The rotating regulating plate is provided to be suspended from the regulating shaft.

Further, according to the present invention, in a product storage shelf provided with a product transport path for rotatably storing a cylindrical product input from a product input port, the product storage shelf is provided on both side walls in the product input port so as to extend vertically. A pair of long holes and both ends are inserted and locked between the long holes so as to be movable up and down, and locks a product put in a non-rollable position to prevent entry into the product transport path. And a regulating shaft that moves up and down when pressed against the outer peripheral surface of the product put in the rolling-possible posture to allow entry of the product, and is provided movably on a rolling road surface facing the regulating shaft. And a regulating guide for restricting the diameter of a product that can pass through the regulating shaft.

(E) Function In the present invention having such a configuration, when a product in a rollable posture is put in, the outer peripheral surface of the product first contacts the regulating plate and rotates while rolling on the rolling road surface. Due to this rotation, the regulating plate is in a state in which the regulating shaft is lifted up with the contact point with the product as a fulcrum, and the upward movement is facilitated. Then, the input product pushes up the regulating shaft and moves upward and retreats in the elongated hole, and slips under the regulating shaft. Further, when a product in a non-rollable position is loaded, the product is locked to the regulating shaft regardless of whether the product is in contact with the rolling road surface or when the product is lifted off the rolling road surface. As a result, entry into the product transport path is prevented.

In addition, the present invention, when a product in a rollable posture is put in,
While rolling on the rolling road surface, the product retreats and moves the regulating shaft upward in the elongated hole by the outer peripheral surface, and slips under the regulating shaft. When a product in a non-rollable position is loaded, the product is locked to the regulating shaft regardless of whether the product is in contact with the rolling road surface or when the product is lifted off the rolling road surface. To prevent entry into the product transport path. In addition, when the regulating guide is positioned to face the regulating shaft, the diameter of a product that can pass between the regulating shaft and the regulating shaft is limited.

(F) Example Each figure shows an example of the present invention. Reference numeral 1 denotes a product storage shelf provided in the vending machine. Of a plurality of types of cylindrical products to be stored, the side walls 2 and 3 are suspended at a predetermined interval slightly longer than the length of the longest product. In addition, between the side walls 2 and 3, the curved traveling members 4 are arranged in opposition to each other with a predetermined interval slightly larger than the diameter of the thickest product among a plurality of types of cylindrical products to be stored. In addition, a merchandise conveying path 5 is formed which extends in the vertical direction while bending and stores the merchandise so as to be able to roll.

A product insertion port 6 is provided at an upper end of the product transport path 5 and a delivery port 7 is formed at a lower end. The delivery port 7 is provided with a delivery device 8 for controlling delivery of one product at a time for each sales command.

Reference numeral 9 denotes a pair of long holes respectively provided on both side walls 2 and 3 in the product insertion port 6, and the openings 9 extend so as to extend in a vertical direction which is substantially perpendicular to the rolling path surface 10 of the product insertion port 6. Has formed.

Reference numeral 11 denotes a regulating shaft having both ends inserted into the long holes 9, 9 on both side walls 2, 3 so that the inside of the long holes 9, 9 can be moved up and down. A regulating plate 12 curved so as to protrude in the direction of the mouth 6 is provided in a suspended state. In the normal state, a gap smaller than the diameter of the small-diameter product A is formed between the rolling road surface 10 at the lower end of the long holes 9, 9 due to the weight and the weight of the regulating plate 12, and When A and large-diameter product B are loaded in a rollable position, the product A,
The products A and B are configured to be able to be retracted and moved to an upper position where products A and B can be normally pushed by being pressed against the outer peripheral surface of B.

That is, when the regulating shout 11 is located at the lower end of the elongated holes 9, 9, the distance C between the regulating shaft 11 and the rolling road surface 10 is
The small-diameter product A is supported by the elongated holes 9 and 9 so as to form an interval smaller than the diameter D of the small-diameter product A and larger than the radius E of the large-diameter product B. Road surface 1
It is set so that it can be moved between 0 and the upper position where the large-diameter product B can pass.

When the regulating plate 12 is pressed and rotated rearward by the inserted small-diameter product A or large-diameter product B, the regulating plate 12 becomes lighter on the regulation shaft 11 side with the contact point between the regulating plate 12 and the products A and B as a fulcrum. The balance is such that the lower end side is heavier, and the regulating shaft 11 is configured to float upward.

Reference numeral 13 denotes a regulation guide provided on the rolling road surface 10, and has a rear portion provided at a position facing the regulation shaft 11 so as to be movable back and forth so as to be able to advance and retreat. When the regulating guide 13 is moved to the rear position and the rear portion advances to a position facing the regulating shaft 11, the gap F between the regulating guide 11 and the regulating shaft 11 moved to the upper position of the elongated holes 9, 9 is reduced. It is configured to be smaller than the diameter dimension of the large-diameter product B and larger than the diameter dimension of the small-diameter product A.

The regulating guide 13 is provided with support holes 14 and 15 which extend long and open in the front-rear direction on both sides thereof, and a pair of front and rear support rods 16 and 17 provided between the side walls 2 and 3 are provided. Support hole
It is supported to be able to move back and forth through 14,15. The support holes 14 and 15 are provided at the front and rear ends with locking projections 18 for locking and holding the support rods 16 and 17 in a detachable manner, respectively.
7 can be locked and held at the front end or the rear end of the support holes 14 and 15.

 Next, the operation of the above configuration will be described.

The regulating shaft 11 is supported by the lower ends of the elongated holes 9, 9 by its own weight, and the regulating plate 12 is in a state of being rotatably suspended.

Here, the loading operation of the small-diameter product A will be described first. In this case, the control guide 13 is moved rearward so that the support rods 16 and 17 pass over the locking projections 18 provided at the front portions of the support holes 14 and 15,
The front end is locked and held. This guides the regulatory guide 13
In the state in which the rear portion is in an advanced state in which the rear portion is opposed to the regulating shaft 11, the distance F between the regulating shaft 11 and the large-diameter product B is larger than the diameter of the small-diameter product A when moving to the upper position of the long holes 9,9. Is formed smaller than the diameter of

Here, when the small-diameter product A is loaded in a normal rollable posture (a posture in which the axial direction of the product is orthogonal to the product insertion direction and can be rolled to the back of the product insertion port 6), FIG. As shown in the figure, the small-diameter product A first comes into contact with the upper portion of the regulating plate 12 so that the regulating plate 12 is pressed and rotated rearward.

Due to the rotation of the regulating plate 12, the regulating plate 12 is in a balanced state in which the lower end side is heavy and the regulating shaft 11 side is light with the contact point with the product A as a fulcrum.
9,9 It is in a state where it is easy to move upward.

Therefore, the small-diameter product A is further rotated by pressing the regulating plate 12 to press and move the regulating shaft 11 upward, pass between the regulating shaft 11 and the regulating guide 13, and roll into the product transport path 5 to be stored. Is done. After passing the small diameter product A, the regulating shaft
11 moves to the lower end of the elongated holes 9, 9 by its own weight and returns, and the regulating plate 12
Rotates and returns to the suspended state.

When the small-diameter product A is loaded in a non-rollable position (a vertical position in which the axial direction of the product is parallel to the product input direction and cannot be rolled), as shown in FIG. The end surface of the small-diameter product A in the loading direction is locked by the regulating shaft 11 and is prevented from entering the product conveyance path 5 deep.

In this setting state, the large-diameter product B moves to the upper position of the long holes 9 and 9 when the regulating shaft 11 and the regulating guide 13 are moved.
Is smaller than the diameter dimension of the large-diameter product B, and is stopped by the regulating shaft 11, so that the product F is prevented from entering the product conveyance path 5 deep.

On the other hand, when a large-diameter product B is to be loaded, the control guide 13 is moved toward the front so that the support rods 16 and 17 can pass over the locking projections 18 provided at the rear portions of the support holes 14 and 15 and engage with the rear end. Into the holding state.

As a result, the regulation guide 13 is in a retreat state in which the rear portion is separated from the position facing the regulation shaft 11, and the distance F between the regulation guide 11 and the regulation shaft 11 when moved to the upper position of the elongated holes 9, is equal to the diameter of the large-diameter product B. It is formed larger than.

Accordingly, the large-diameter product B loaded in the rollable posture rolls on the rolling path surface 10 from the regulation guide 13 by the same operation as the above-described operation of loading the small-diameter product A, and rolls with the regulation shaft 11. It passes between the road surface 10 and rolls to the back of the product transport path 5 and is stored.

In addition, the small-diameter product A inserted in the non-rollable position is locked by the regulating shaft 11 and is prevented from entering the product conveyance path 5 deep.

(G) Advantages of the Invention Since the present invention has the above-described configuration, it is possible to reliably prevent entry of a product having a non-rollable posture even if the product has a large diameter and a small diameter with a simple configuration, and to perform rolling. When entering a possible posture product, even if there is a large difference in the diameter of the product within the storable range, there is an effect that the regulating shaft can be easily moved upward by the input product and can pass therethrough. .

Further, the present invention can prevent the entry of the product in the non-rollable position reliably even if the product has a large diameter and a small diameter with a simple configuration, and can operate the controllable guide in the rollable position when the small-diameter product is supported. In this case, even if the product is a large-diameter product, it is possible to prevent the introduction of the large-diameter product and to prevent the mixing of different types of products.
