[Prior Art]

 Conventionally, as shown in Japanese Utility Model Laid-Open No. 61-99274, products that are stacked and stored in a product storage rack are reciprocally rocked by a crank mechanism by a link mechanism, and products are delivered in order from the lowest one. A unloading device has been proposed.

[0003]

[Problems to be solved by the device]

 In this conventional device, only one product is dispensed by the swing of the pusher, but it is also known that one product is alternately dispensed by one reciprocating swing of the pusher. ..

However, with this alternate dispensing system, two rows of products are vertically stacked and stored in the product storage column, and product discharge outlets are provided on both sides at the bottom of the product storage column. Therefore, when one product is in the process of being dispensed, it is necessary to take preventive measures to prevent it from being pushed out diagonally from the product dispensing outlet and falling out while the other product falls to the lowest position of the next selling position. There is.

Further, when a plurality of product storage columns of this two-row product alternating delivery system are arranged side by side in the left-right direction when viewed from the front in the main body, the space between adjacent product storage columns is dispensed. It serves as a common product drop passage through which released products are released.

Therefore, from the viewpoint of increasing the number of products to be stored, it is preferable that the product storage columns are closely arranged in parallel, while the product storage column is provided with a product fall prevention mechanism, so that the storage space is secured. However, it is not preferable that the product storage column becomes large.

The present invention has been made in view of the above problems, and is equipped with a small-sized and space-saving product fall prevention mechanism, which enables a large number of product storage columns to be installed and saves space in the width direction of the main body. It is an object of the present invention to provide a product discharge device for a vending machine, which can be effectively used to improve the storage efficiency.

[0008]

[Means for Solving the Problems]

 According to the present invention, products are stacked and stored in two rows, and a product storage column having product outlets on both lower sides, a product mounting base provided below the product storage column, and the rotation of the motor are cranked. It is converted into reciprocating swinging motion via a mechanism, and automatically equipped with a lower-end pivotal product dispensing link arm that dispenses products one by one from the lowest position alternately at the tip of the product extruding section to the opposite side. In the vending machine, the product push-out section of the product delivery link arm has a U-shaped frame corresponding to the products in each row, and when one side of the product is sold, the other side of the descending next sales product is received. A pair of guards are installed to prevent accidental fall from the product outlet, these two guards are linked and linked by a link, and the guards are kept horizontal on the base during movement, and after the sale ends, along the corner surface of the base 90 Downturn Also of a is configured so as to be accommodated situation in commodity storage column to rotate the.

[0009]

[Action]

 The products to be sold are on the base, and the next products to be sold are on the product delivery link arm. On the other hand, the guard is held horizontally on the base on the side of the product for sale, and is rotated 90 degrees downward on the side of the next product for sale. When the product delivery link arm moves due to a sales order, both guards perform the opposite operations. That is, on the selling side, it rotates 90 degrees downward, and on the next selling side, it is pulled up and moves horizontally on the base. Therefore, by surrounding the next sale product that loses the support of the link arm with this horizontal guard, it is possible to prevent double sale that accidentally falls from the product outlet.

A partition wall 2 partitions the products M so that they are arranged in two rows in an orderly manner. The partition wall 2 is provided at the center of the rear wall of the product storage column 1 so as to project toward the front side by a predetermined length. The partition wall 2 also facilitates the insertion of the product M 1 when the product M 1 is inserted from the front side and replenished. The lower parts of the left and right side walls of the product storage column 1 are cut out and opened to provide product delivery outlets 3A and 3B. 4 is provided in the lower part of the product storage column 1 and is a base on which the product M is placed. The width L2 of the base 4 is shorter than the width dimension L1 of the product storage column 1 in the product delivery direction. Then, the central portion of the base is opened 4b, and the upper portion of the product dispensing link arm 5 (hereinafter abbreviated as a link arm) that functions as a pusher for pushing out the product M, that is, the product pushing-out portion 5a is projected, and the swing thereof is performed. Free movement. Therefore, as shown in FIG. 4, the product M has both front and rear end portions mounted on the base surfaces 4a, 4a.

The base 4 is in the shape of a box, and the mechanical parts of the product unloading device are incorporated therein. That is, the gear motor 6 is fixed to the side portion of the base 4, while the link arm 5 is pivotally supported at its lower end by the arm support shaft 7. Although not shown, the rotation of the gear motor 6 is controlled by a cam and a switch.

The arm support shaft 7 is attached and fixed to a pair of projecting pieces 9 provided on a substrate 8 that is assembled with the base 4 at a lower portion. Reference numeral 10 denotes an output shaft of the gear motor 6, and a crank wheel 11 is fixed to the output shaft 10. The crank wheel 11 includes a crank shaft 12. The crankshaft 12 is engaged with an elongated hole 13 formed in the intermediate portion of the link arm 5. Therefore, when the crank wheel 11 rotates in the direction of the arrow, the link arm 5 reciprocates left and right with the arm support shaft 7 as a fulcrum by one rotation operation.

As understood from FIG. 1, the product pushing-out portion 5a at the tip of the link arm 5 engages with the rear side of the product M 1 and pushes it out. Numerals 15 and 16 are guards for preventing the product M on the non-dispensing side from falling from the product payout outlets 3A and 3B during the product payout. It serves as a part that prevents products from falling.

The two guards 15 and 16 are pivotally connected to the upper part of the link arm 5. That is, the long holes 17 and 18 are provided in the upper part of the link arm 5, the shafts 19 and 20 provided at the rear end portions of the guards 15 and 16 are inserted into the long holes 17 and 18, and both guards 15 and 16 are inserted.

With this configuration, the guards 15 and 16 are guided and supported by riding on the upper surface of the base 4.

Therefore, in FIG. 1, when the delivery of the products M in the left column is completed, the left guard 15 is rotated 90 degrees downward to be housed in the product storage column 1, and the right guard 16 is installed. Are held horizontally. After that, when the link arm 5 starts to swing to the right and the product M in the right column is delivered, the product M on the right side is pushed out to the right, and the left guard 15 is driven by this. When it hits the corner portion 4R of the base 4, it is pulled up to be in a horizontal state as shown by the dotted line, and is guided and moved to the right as it is. As a result, the support by the link arm 5 is lost when the right-side product M is sold, and the left-side product M that is pushed down is prevented from being accidentally dropped from the product dispensing outlet 3A.

As shown in FIG. 5, a plurality of product storage columns 1 are arranged side by side in the left-right direction when viewed from the front, and the space between the product storage columns 1 and the product storage columns 1 has a product drop passage 2 5 are shared.

In the present invention having the above-mentioned configuration, the product unloading operation will be described next.

In the sales standby state of FIG. 1, when the crank wheel 11 is rotated by the drive of the gear motor 6 based on the sales command, the link arm 5 swings to the right and the sales operation of the product M in the right column is performed. To do. As shown in FIG. 2, during the unloading operation of the products M in the right row, the left guard 15 is guided by the corner portion 4R of the base 4 and pushed up as shown, and is supported substantially horizontally by the base surface 4a. Move to the right. At this time, since the left and right guards 15 and 16 are interlocked by the link 21, even if the shaft support structure by the elongated holes 17 and 18 can be maintained substantially horizontal.

When the link arm 5 further moves to the right, the right product M is dropped and sold, and the next right product M stops on the link arm 5. When the link arm 5 further moves to the right side, the product M on the left side falls from above the link arm 5 and stops on the base 4.

At this time, since the left-side guard 15 is maintained in a substantially horizontal position, the frame front surface 15a guards the product payout outlet 3A and prevents the product M from falling from the base 4.

FIG. 3 shows the state at the time of sale, in which the link arm 5 is moved to the right at maximum, and after the sale is finished, the right guard 16 is disengaged from the base surface 4a and rotated downward by 90 degrees. With this, the product is on standby, and the left-hand side product M will be sold for the next shipment.

As described above, since the guard is rotated downward by 90 degrees after the end of sale, when the product storage columns are arranged in parallel as shown in FIG. Since it can be used, the space in the width direction of the vending machine body can be effectively used.

From this, it is possible to increase the number of columns arranged side by side to increase the number of articles accommodated.
