In addition, the auxiliary stopper (1510, 61 is the product aisle (7)
As shown in Figure 7, the products to be stacked and stored inside the container are those that do not leave gaps between the product and the product (5) when stacked, such as box-shaped paper containers for beverage products. If there is, the locking part On is pressed against the side of the product next to the lowest product placed and locked on the main stopper 0.0)old,
It is configured so that it can be locked and held between the product storage column (1) and the side wall of the product storage column (1), and when the product (A) is stored in a stack like a cylindrical canned beverage product (not shown in FIG. 11), A
) If the product has a gap (I3) between the main stopper (
10) The locking portion (171) is made to protrude from the gap fB formed between the lowest product placed and locked on Ill and the next product so that the next product can be locked and held. It is composed of

Next, the operation of the above configuration will be explained. Delivery cam (8
) is in a position where the drive part (8b) is extended forward and the control member (9) is placed and supported on both sides of the main stoppers (10) (lυ) and extended approximately horizontally into the product passageway (7). When tightening, the product prisoners are stacked and stored on each raw stopper (10).The locking cam drive drive part (18a) is connected to the drive shaft between the auxiliary stoppers (16) on both sides. (5)
Therefore, each auxiliary stopper Q5) (
The locking part 07) of 16) is positioned directly outside the product passageway (7). This state is a sales delivery standby state and is shown in FIGS. 5 and 6.

When a predetermined amount of money is inserted and a predetermined operation related to sales is performed during this sales sending standby state, a sales sending command is sent to the electric motor (6), and the electric motor (6) drives the drive shaft (5). In FIG. 6, it rotates 180 degrees in the direction of the arrow and then stops. Due to this rotation of the drive shaft (5), the drive part (18a) for the square locking cam presses the auxiliary stoppers (15) (1, 6), respectively, and moves the locking part (lη into the product passageway (7)). The drive part (8b) of the delivery cam (8)
) moves the control member (9) in the direction of the arrow in FIG. When the end of the control member (9) reaches the vicinity of the shaft support of the king stop spring u1), the end of the delivery spring 04) (t
4a) is locked to the end of the elongated hole (9a) of the control member (9) to generate elasticity, and the end of the control member (9) is connected to the main stopper 01.
] When the support is released, the elasticity of spring 04) and the product (A, )
The main stopper 1ll) is suddenly rotated downward under the load of , and the product (A1) is sent out downward. This state is the seventh
As shown in FIG.

Then, when the drive shaft (5) rotates further, the control unit (9), which was placed and supported by extending far below the main shaft (10), is moved by the delivery cam (8) as shown in Fig. 7. Then perform a return movement 'AJJJ' in the direction of the arrow. Therefore, the main strike q
D is pressed into the product passage (7) by the control member (9), and as the control member (9) moves, it gradually extends into the product passage (force) and is supported. At the beginning of the return movement, the sending spring circle is inserted into the long hole (14a) at the end (14a).
9a) It is released from the locked state with the end portion, becomes free in the elongated hole (9a), and elastically disappears. Also, the control member (
9) The king stopper circle mounted and supported is rotated upward from the horizontal position by the elasticity of the sold-out detection knob Q21 to the rotation position '1-'.
However, when the drive shaft (5) rotates to this state, the locking cam drive part (18a) becomes auxiliary stop 0ω (I6).
Auxiliary stones"+15 to release the oppression of
1 (1+i) locking parts Q71 are respectively product passages (7)
Rotate outward to release the products (A3) and (A4). Therefore, the unlatched product (A,) falls onto the main stopper 01) under its own weight, resists the elasticity of It is rotated to a position where it is supported by and locked.

Then, the drive shaft (5) completes 180 degrees of rotation, the electric motor (6) stops, and the control member (9) is moved by the delivery cam (8) to the main stoppers (1,0) (1,1) on both sides. One sales operation is completed in a state in which they are placed and supported in the same extended position on the lower surface of the , and the sales sending standby state is entered. This state is shown in FIGS. 9 and 10.

When the next sales sending command is sent to the electric motor (6), the sending cam (8) moves the control member (9) in the direction of the arrow in FIG. The product (A2
) to send out and sell. That is, each time a sales sending command is issued, the drive shaft (5) rotates 180 degrees to perform one sales sending operation.
Product aisles (71) on both sides (71 products are delivered and sold alternately.

The electric motor (6) is configured to be capable of forward and reverse rotation, and by rotating the electric motor (6) forward or reverse in response to a sales sending command and rotating the drive shaft (5) 180 degrees forward or reverse, the left and right It is possible to store and send out and sell products of different types (different contents, or cans and paper containers sold together, etc.) or products of different prices in the product aisle (71(7)).

(f) Effects (1) Since the present invention is constructed as described above, it is possible to store a much larger number of products than the spiral method or the elevator method, and the device is simple, making assembly easy and inexpensive. You can get it.

(2) Since the present invention allows the product to be delivered to be locked with the large main stopper, even when a product that is easily deformed, such as a beverage product in a paper container, is stored and locked for a relatively long time,
There is little deformation of the lowest product due to the product load (therefore, the product can be delivered reliably, and the quality of the product's shape is not degraded, making it difficult to destroy or remove the product from the bottom of the product aisle. Such pranks are also difficult to pull off.

(3) Since the present invention has a configuration in which the linear forward and backward movement of the control member is guided by a pair of guide parts provided on the lower surface of the main stopper, reliable and smooth movement can be achieved without the need to provide a special guide member etc. In addition, an inexpensive device with a simple structure can be obtained.

(4) Since the present invention is configured such that the main stopper that controls the delivery of the product also serves as a sold-out detection member, there is no need to provide a special detection member for detecting the sold-out of the product. Therefore, there is no need to change the size, shape, etc. of the detection member depending on the shape and size of the stored product, and the product can be detected reliably regardless of its shape and size as long as it can be stopped by the main stopper. It is possible to detect the sold-out state of the product. Furthermore, since the main stopper is also used as the detection member, there is no need for the detection member to protrude near the king stopper as in the conventional case, and therefore, there is no possibility of product jamming caused by the detection member.

(5) The present invention provides a delivery spring that generates elasticity when the control member retreats when the main stopper rotates due to the retreat movement of the control member, and the main stopper is forcefully rotated by the elasticity of the spring. Since the structure is such that the product is sent out by opening the moving product passage, it is possible to quickly send out a single product and also to ensure reliable delivery of the product.

Force (force) The products (A3) (A4) are rotated outward to release the locking. Therefore, the released product (A3) falls onto the main stopper (11) under its own weight and springs. The main stopper (11) is rotated and locked by the control member (9) against the elastic force of θ until it is horizontally supported.Then, the drive shaft (
5) completes 180 degree rotation, the electric motor (6) stops, and the control member (9) is extended equally to the lower surface of the main stoppers (10) (l l) on both sides by the delivery cam (8). One sales operation is completed in the state where it is placed and supported in the protruding position, and it enters a sales sending standby state. This state is shown in Figures 9 and 10.
As shown in the figure. When the next sales sending command is sent to the electric motor (6), the sending cam (8) moves the control member (9) in the direction of the arrow in FIG. 9 to release the support of the main stopper 00),
Product (N2) by performing an action similar to the above action.
Send out and sell. In other words, every time a sales sending command occurs, the drive shaft (
5) is rotated 180 degrees to perform the one-sale sending operation.No.11
, product aisles (7) on both sides (products are sent out and sold alternately. By rotating the drive shaft (5) 180 degrees forward or reverse, you can store different products (items with different contents, or cans and paper containers sold together, etc.) in the left and right product aisles (7) (7). Or, it can be stored in products of different grades and sent out for sale.
θ3) are made into independent circuits, and the product passage (force (
7) can be individually sold out. (f) Effects (1) Since the present invention is constructed as described above, it is possible to store a much larger number of products than the spiral method or elevator method, and the device is simple, making assembly easy and inexpensive. can be obtained. (2) Since the present invention allows the product to be delivered to be stopped by the main stopper with a large surface, even when a product that is easily deformed, such as a beverage product in a paper container, is stored and locked for a relatively long time,
There is little deformation of the lowest product due to the product load, so the product can be delivered reliably and the quality of the product's shape will not be degraded (in addition, the product will not be destroyed or taken out illegally from the bottom of the product aisle). (3) Since the present invention has a configuration in which the linear forward and backward movement of the control member is guided by a pair of guide parts provided on the lower surface of the main stopper, it is not necessary to provide a special guide member, etc. It is possible to obtain a reliable and smooth operation without unnecessary operation, and to obtain an inexpensive device with a simple structure. (4) In the present invention, the main stopper that controls the delivery of the product can also be used as a sold-out detection member for the product. Since it is configured to double as a sensor, there is no need to provide a special detection member for detecting sold-out products.Therefore, the size and shape of the detection member can be changed depending on the shape and size of the stored products. The sold-out state of the product can be reliably detected regardless of the shape and size of the product as long as it can be stopped by the main stopper.The main stopper also serves as a detection member. Therefore, unlike in the past, the detection member does not protrude in the vicinity of the main stocker (therefore, there is no possibility of product jamming due to detection radiation). When the main stopper rotates due to the retracting movement, a delivery spring is provided that generates elasticity when the control member retracts, and the elasticity of the spring forcefully rotates the main stopper to open the product passage and release the product. Since the product is configured to be sent out, the product can be delivered quickly and reliably. 4.
