Abstract

PURPOSE:To make it possible to stack plural line of commodities in the depth direction of an automatic vending machine and to reduce the depth size of the automatic vending machine by preparing an endless track for driving plural extruding pieces for extruding commodities in the horizontal direction in one direction at each prescribed pitch in each detection of a discharging instruction. CONSTITUTION:At the time of detecting a commodity discharging instruction, a sprocket 19 of the endless tack 16 is rotated in the arrow D direction, the commodity 22a on the forefront line is extruded forward through the final line commodity 20a and the center line commodity 21a and dropped into a front shoot 9. Thus, one commodity can be discharged from a commodity take- out port 10 by driving the endless track 16 only by two extruding pieces 18a. Namely, the commodities are extruded in one direction by the extruding pieces 18a fixed to the endless track 16. Consequently, two lines or more of commodities 20a, 21a, 22a can be stacked and stored in the depth direction and the depth of the automatic vending machine body can be thinned as compared with a conventional machine through the number of commodities is comparatively large.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a direct stacking type product dispensing device. 2. Description of the Related Art This type of direct stacking type product dispensing device is constructed as shown in FIG. In the stocker 1, products 2 a m 2 b ”, 3 as 3 b, etc. are stored in two rows, and the bottom 4 of the stocker 1 is slidable in the arrangement direction of the stacked product rows A and H. extrusion piece 5
is provided. The push-out piece 5 is driven by a motor via a rotation/linear reciprocating conversion mechanism 6 that converts rotational motion into linear motion. When the push-out piece 5 moves from the solid line position to the imaginary line position,
The product 2a at the bottom of the product row A is pushed out by the pusher piece 5, passes through the payout port 8 of the stocker 1, and is delivered to a position 9211 facing the product takeout port IO via the front chute 9. A first limit switch I2 is provided at the front end position of the stocker 1, and when the first limit switch I2 detects the push-out piece 5, the operation of the motor is terminated. When the dispensing instruction is detected again, the operation of the motor is restarted, the pushing piece 5 slides toward the product row B, and the product 3a at the bottom of the product row B is pushed out by the pushing piece 5 and passed through the rear chute 13. Payout exit! It is paid out through 4. A second limit switch I5 is provided at the rear end position of the stocker 1, and when the second limit switch 15 detects the push-out piece 5, the operation of the motor is terminated. Problems to be Solved by the Invention In such a conventional configuration, it is necessary to provide a front chute 9 and a rear chute 13 inside the vending machine.
The depth of the vending machine becomes thicker even though the products are stacked and stocked in only two rows in the depth direction of the vending machine. Furthermore, because products can only be stacked and stocked in two rows, it is currently impossible to increase the number of products that can be accommodated. To provide a direct stacking type product dispensing device capable of stacking and stocking products in two or more rows in the depth direction and making the depth of a vending machine main body thinner than before in relation to the number of products accommodated. With the goal. Means for Solving the Problems The direct stacking type product dispensing device of the present invention is a product dispensing device that pushes out the lowest product of directly stacked products laterally with a pusher piece and sequentially dispenses the product, and it The present invention is characterized in that an endless track is provided that drives the extrusion piece in one direction at a predetermined pitch each time it is detected. Effect: According to this configuration, each time a dispensing instruction is detected, the pushing piece attached to the endless track pushes out the product in one direction. For example, if the products are stacked in three rows in the depth direction and the outward path of the endless track is driven forward, the last product in the three rows will be pushed out into one product with a push-out piece. Every time you push out the length, the product is pushed out. The pushing piece passes under the product and returns to the initial position through the return path. EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. Components having the same functions as those in FIG. 6 showing the conventional example will be described with the same reference numerals. As shown in FIG. 1, the product dispensing device of the present invention has an endless track 11i installed below a stocker 1a that stacks products in three rows in the depth direction C of the vending machine. The bottom 4 of the stocker 1a has a depth direction C as shown in FIG.
A slit I is formed in the slit I, and this slit 17 is connected to the four extruded pieces 1 attached to the endless track 16.
8a can pass through. Extruded piece 1
The length of one of the pieces 8a is (1/2) of the length of the product. Note that, as shown in FIG. 2, a plurality of stockers la, lbe, . . . are provided inside the vending machine, and an endless track IG is provided for each stocker. Since all stockers are similar, the case of stocker 1a will be described as an example. When a product dispensing instruction is detected in the state shown in FIG. 1, the sprocket 19 of the endless orbit te is driven to rotate in the direction of the arrow, passing the product 20a in the last row and the product 21a in the center row to the product 22a in the front row. is pushed forward and falls into the front chute 9 as shown in FIG. In this way, one product can be delivered to the product outlet 10 by operating the endless track IG for two push-out pieces 18a. When a dispensing instruction is detected in the state shown in FIG. 3, the endless track IG is further driven by two pushing pieces 18a, and as shown in FIG.
a is pushed out and delivered to the product outlet 10. Fourth
When a dispensing instruction is detected in the state shown in the figure, dispensing of the product is executed in the same manner as described above, and the product 20a is dispensed to the product takeout port 10. By passing the push-out piece 18a, the products 20b, 21b, and 22b of each row that are second or higher from the bottom are pushed to the bottom 4.
fall on top of. After the product 20a has been completely dispensed, the endless track 16 is operated until the pushing piece 18a returns to the initial position shown in FIG. 1 in preparation for the next dispensing instruction. In this way, the rear chute 13 seen in the conventional example shown in FIG. 6 is not required, and the depth of the vending machine can be reduced. Additionally, products can be stacked in three rows in the depth direction of the vending machine, increasing the number of products that can be accommodated relative to the depth. In the above embodiment, there are four extruded pieces 18 on the endless track IG.
a, which is an endless orbit IG as shown in Figure 5.
Waiting time can be shortened by attaching push-out pieces 111a and 18b at multiple locations. In the above embodiment, the case where the products are piled up in three rows in the front and back direction has been described as an example, but the products can also be dispensed in two or four or more rows. Effects of the Invention As described above, according to the present invention, an endless track is provided that drives a pusher piece that laterally pushes out the lowest product of direct stacked products in one direction at a predetermined pitch each time a delivery instruction is detected. Therefore, products stacked in multiple rows in the depth direction of the vending machine can be pushed out in order toward the front of the vending machine, eliminating the need for one of the two chutes seen in conventional models. , the depth dimension of the vending machine can be reduced. Further, even if products are stacked in three or more rows in the depth direction of the vending machine, the products can be dispensed in order, and the number of products stored can be greatly increased.
