The present invention relates to a product dispensing apparatus of a vending machine that extracts and sells the lowest product from a stacked product line.

As such a vending machine, the structure disclosed by Unexamined-Japanese-Patent No. 63-12266 is known, for example.

This prior art is to arrange the product storage column (column) in two rows to store the goods (superimposed) in the goods loading target, and to install the extrusion member for reciprocating the upper surface of the goods loading table below the goods storage column.

And the extrusion member is located directly under one of the goods columns, and moves from the state of supporting the lowest goods in the goods storage column to just below the other goods storage column. The lowest goods of the goods storage column are extruded from the goods extruder formed between the wall of the goods storage column and the goods loading stand by the extrusion member, and the goods in the next export order are the lowest of the other goods storage column. It is comprised so that it may be supported by an extrusion member as a commodity.

By the way, in order to sell thin and long articles, such as gum, in the vending machine of the said structure, it is common to arrange the goods which have two rows of goods storage columns superimposed inside each other so that they may mutually face in the longitudinal direction.

However, when an elongated shape product is sold, when the distance between the wall of the product storage exit side and the product column superimposed on the product storage column is large, when the extrusion member moves to eject the product from one of the product storage columns, The product of the other goods storage column supported by the product may fall to the goods loading stand in an inclined state, and the product of such a state is locked by the edge of the product extruder even when the product is subsequently extruded by the extrusion member. There is an absurd point. For this reason, conventionally, there is a problem in that a manufacturing cost is increased because a dedicated product male column has to be manufactured according to the size of each product or an auxiliary device so that a gap does not occur between the wall of the product storage column and the product row.

In addition, conventional vending machines require two spaces to be taken out in order to extrude goods alternately from opposite sides of two rows of commodity storage columns arranged side by side. There was also a problem that the number was limited.

The present invention not only can extrude a thin and long shaped product by releasing each product to the same position in front or rear from two rows of goods formed by overlapping goods in the front and rear directions, but also provides a space for carrying out the goods at least. An object of the present invention is to provide a product dispensing apparatus for a vending machine.

According to the present invention, a product storage column in which two left and right rows are stacked in an up and down direction and stored thereon is placed on the bottom of the product loading column for placing the lowest two goods in the above-described order, and the above-described lowest goods are moved from the product ejection outlet. Two extruded members provided for each product to push in the direction, an endless transfer member which rotates by fixing the extruded member at a position to extrude the lowermost goods alternately every half turn; Fixing the extruded member to the conveying member and at the same time, fixing member for protruding both terminal portions in the lateral direction, and passing both terminal portions of the protruding fixing member with the rotation of the conveying member. The guide unit is installed to guide the extrusion member in the direction of the product extrusion port.

In addition, the present invention provides a product storage having a partition plate that is attached when stacked in two rows in the left and right in the vertical direction, and detachable when storing a large product, and a product mounting table for mounting the lowest product described above A column, two extrusion members for extruding the lowermost goods in the front-rear direction from the product extruder, and an endless transfer member which fixes and rotates the goods member, wherein the goods are stacked and stored in two rows. If there is an extruded member is located at the position of alternately extruding the lowest goods every time the transfer member is rotated halfway, and the transfer member is positioned so that both extruded members are arranged side by side in a row when a large product is stored It can be attached to.

With this configuration, the lowest goods stored by stacking them in two columns in the vertical direction in the vertical storage column are rotated by rotating an endless transfer member having two extruded members fixed at positions where the product is extruded alternately every half turn. Can be extruded.

In addition, both ends of the fixing member for fixing the extrusion member to the conveying member pass through the guide portion, whereby the extrusion member can be guided in the direction of the product extrusion port.

In addition, by separating a partition plate by installing a partition plate that is detachable from the merchandise storage column, large items can be stored.

In the case of storing a large product, the large member can be attached to the transfer member at a position arranged in a line, and the large product can be extruded by a line of extruded members.

EXAMPLE

[Example 1]

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

1 is a front view of a main part of a vending machine according to an embodiment of the present invention, and FIG. 2 is a side view of the main part thereof.

1 and 2, 1 is a product dispensing apparatus, and 2 is a product storing column of the product discharging apparatus 1.

The product storage column 2 is formed by bending a metal flat plate into a shape having a long cross section. The opening part of the front surface is formed as a product inlet 3, and on both sides of the product inlet 3, the product is dropped. The flange 3a for prevention is provided, and the product extrusion port 2a is formed in the lower part.

In addition, the rear plate 4 of the product storage column 2 is provided with a rear plate 4 for product pushing which can be moved in the front and rear direction. The partition plate which protrudes to the front side by a predetermined length is provided on the rear plate 4. (5) is integrally installed.

Here, the partition plate 5 is arranged in a line with the longitudinal direction in the front-rear direction without overlapping the thin and long articles 6 and 7 such as gum stored in the product storage column 2 laterally. It is for stacking and storing.

8a and 8b are installed in the lower part of the goods storage column 2, respectively, and mount the lowest goods 6a and 7a of each row, and simultaneously provide the movement groove 9 for guiding the movement of the extrusion member mentioned later, respectively. This is a guide block, which is a pair of goods loading stand formed in the center.

And below this pair of guide blocks 8a and 8b, the goods conveying apparatus 10 driven by the selling instruction from the sale control apparatus which is not shown in figure is provided.

As shown in FIG. 3 and FIG. 4, the commodity conveying apparatus 10 has a pair of gear motors 10a provided on the side and fixed to the output shaft 10b of the gear motors 10a at predetermined intervals. A pair of driven sprockets (not shown) fixed to the drive sprocket 10c and the driven shaft 10d provided in front of the output shaft 10b so as to face the drive sprocket 10c, and these drive sprockets 10c and driven It consists of a pair of transfer chains 10e which are endless transfer members provided respectively over the sprockets, and two extruded members 11 each having an angle to the transfer chain 10e.

Here, the goods conveying apparatus 10 is driven by the selling instruction from a sales control apparatus, when the goods selling button which is not shown in figure is pressed, and rotates the conveying chain 10e.

In addition, the extrusion members 11 face each other so as to push out one of the lowest goods 6a, 7a mounted on the guide blocks 8a, 8a each time the respective transfer chains 10e are rotated halfway. It is attached to the transfer chain 10e.

As a result, when the product selling button is pressed, the pair of transfer chains 10e are rotated, respectively, and one lowermost product 6a, 7a stored in two rows in the product storage column 2 is one of the extruded members 11. Is pushed forward from the product ejection opening 2a to the front of the product storage column 2, and falls.

In addition, the extrusion member 11 pushes the goods 6a and 7a and contacts the switch (not shown), whereby the sales control device stops the driving of the goods transport device 10.

In this way, the conveying chain 10e rotates halfway each time the product selling button is pressed to alternately push out the lowermost products 6a and 7a.

By the way, the next selling product 6b, 7a, on which the lowest product 6a, 7a was mounted at the time of pushing out, was immediately extruded as the lowest product 6a, 7a was pushed out. It is mounted on (11), and after the extrusion member 11 pushes out the lowermost goods 6a, 7a, it falls to the guide blocks 8a, 8b.

However, the next selling product 6b, 7b during this drop is first extruded because its rear end is brought into contact with the upper surface of the guide block 8a, 8b and then falls on the guide block 8a, 8b. There is no rotational movement relative to the member.

Therefore, the product extrusion port 2a is not caught.

On the other hand, the feed chain 10e is formed with a pipe-shaped insertion part 12 around the whole at predetermined intervals.

In addition, four predetermined through-holes 12 of the insertion through portions 12 are inserted through the elongated pins 13, which are fixed members, and the extruded members 11 by the elongated pins 13. ) Is fixed perpendicular to the transfer chain 10e.

In addition, four insertion through holes 14 for inserting these elongated pins 13 are provided in the lower part of the extruded member 11, among which the outer two insertion through holes 14 are long holes. Formed.

As a result, even when the extruded member 11 passes through the outer circumferential portion of the drive sprocket 10c, the extruded member 11 can move up and down by sliding the inside of the long hole 14 up and down. ) Is to pass through the outer circumference of the drive screw (10c) smoothly.

Moreover, the both ends of these elongate pins 13 protrude the same length from both sides of the fixed part with the conveyance body 10e of the lower part of the extrusion member 11 at the same length.

On the other hand, the guide block (8a) (8b) on the left and right side is formed with a guide groove 15, which is a guide for guiding the elongated pin (13) at the position facing the moving groove (9).

And when the extrusion member 11 is conveyed while pushing the goods 6a and 7a on the upper side of the guide block 8a, 8b, this elongate pin 13 is made to pass through this guide groove 15. As shown in FIG.

In addition, when pushing the goods 6a and 7a, the extruder 11 exerts a force, i.e., a reaction, to move in the linear direction opposite to the direction pushed out by the goods 6a and 7a being pushed.

By the way, since the extrusion member 11 in the extrusion start state is located immediately before the bent portion in the guide groove 15, such a linear force is prevented at the bent portion.

Therefore, it is possible to push out goods by using the output of the gearmotor 10a in vain.

In addition, even when the elongated pin 13 passes through the guide groove 15 and the relaxation occurs in the transfer chain 10e, the relaxation of the transfer chain 10e is eliminated in the guide groove 15. The output of 10a) can be used in vain to push the goods out.

Next, a product discharging operation of the vending machine configured as described above will be described.

When the merchandise sales button is pressed and a sales instruction is sent from the sales control device, the gear motor 10a of the merchandise transport apparatus 10 rotates, and in conjunction with this, the pair of drive sprockets 10c rotates to drive the sprocket. 10c) and a pair of transfer chains 10e spanning the driven sprocket rotate.

Then, the extrusion member 11 attached to one of the conveying chains 10e at the standby position shown in FIG. 2 moves the conveying grooves 9 of the guide block 8a by the rotation of the conveying chains 10e. Move in the horizontal direction.

That is, for example, the lowermost commodity 6a in the right row accommodated in the commodity storage column 2 is pushed forward as shown by the arrow and falls from the commodity extrusion port 2a.

In addition, since the extrusion member 11 is located in the bent part of the guide groove 15 at the time of the compression start of the goods 6a by this extrusion member 11, it is reversed by reaction by this goods 6a. There is no movement in a straight direction.

In this way, after the conveying chain 10e is rotated and the product 6a is pushed out, the extruded member 11 abuts on the switch, whereby the sales control device stops driving the product conveying apparatus 10. Let's do it.

At this time, the extrusion member 11 attached to the other conveying chain 10e is located at the standby position for pushing the goods 7a at the lowest position in the left column, and prepares for the next sales order.

In this manner, the extruded members 11 are attached to the pair of transfer chains 10e so as to face each other, and the lowermost products of the two rows stored in the goods storage column 2 are rotated by the transfer chain 10e in accordance with the sales order. (6a) (7a) can be pushed out alternately.

In addition, since the goods 6a and 7a are pushed out in the front direction, the oil refinery space in the transverse direction of the product discharging device can be narrowed.

In addition, the space in front is increased by that much, but since the goods 6a and 7a to be taken out are small goods such as gum, the increase is almost insignificant compared to the size of the inside of the vending machine.

For example, if the distance between the terminal portion of the elongated pin 13 and the guide groove 15 is narrowed as much as possible, and the width of the transverse chain 10e and the extrusion member 11 is widened, the extrusion member ( 11, the extrusion member 11 can push out the goods 6a and 7a without rotating in the horizontal direction even if the force is applied from the transverse direction.

In addition, the transfer chain 10e and the extrusion member 11 are formed in this manner, and at the same time, they are installed to the left and right at a position in which the two extrusion members 11 are opposed to the one transfer chain 10e, thereby providing one transfer chain ( 10e) also alternately pushes out the lowermost commodities 6a and 7a in the second row.

In addition, although the extrusion direction was made forward in the description so far, you may make it push out in the same direction of back.

By the way, in the foregoing description, the product dispensing apparatus for alternately discharging the goods stored side by side in the two rows of the goods storage column has been described. However, the present invention is not limited to this, and the wide goods may be exported. .

Next, another embodiment of the present invention will be described.

[Example 2]

FIG. 5 is a front view of a product dispensing apparatus of a vending machine according to another embodiment of the present invention, and FIG. 6 is a side view.

In addition, in FIG. 5 and FIG. 6, the same code | symbol as FIG. 1 and FIG. 3 has shown the same or equivalent place.

In FIG. 5 and FIG. 6, 5a is a detachable partition plate, which is attached to the back plate 4 when storing narrow products 6 and 7 but when storing large wide products. It can be separated.

Further, the extruded members 11 of the product discharging device 16 are vertically attached to the same positions of the pair of moving chains 10e, respectively.

Here, as shown in FIG. 6, the product discharging device 16 includes a clutch shaft 16a detachably fitted to the output shaft 10b of the gear motor 10a and the clutch shaft 16a. It has the spring 16b which applies a force to the direction which pushes against 10b.

The clutch shaft 16a and the fitting portion 16c of the output shaft 10b have a spline structure.

Here, in the case of moving the extruded member 11 on the left side by side to the side of the extruded member 11 on the right side in order to push out a large commodity, the front end of the clutch shaft 16a is fitted with a spring ( 16b), and then the clutch shaft 16a is rotated in the pushing direction, thereby rotating the drive sprocket 10c and the transfer chain 10e on the left side to move the extruded member 11 on the left side. Doing.

In this manner, as shown in FIG. 5, after the two extrusion members 11 are arranged side by side, when the hands are released, the tip of the clutch shaft 16a is fitted to the fitting portion 16c again by the spring 16b.

In this state, when the product selection button is pressed and the product transport apparatus 10 is driven, the pair of transport chains 10e rotates so that the two extrusion members 11 together push the large product forward and the product extruder ( Drop from 2a).

In addition, after the conveying chain 10e is rotated and the product is pushed out in this manner, one of the extruded members 11 comes into contact with the switch so that the sales control device stops driving the product conveying apparatus 10.

In this way, by attaching the extrusion member 11 at the same position of the pair of transfer chains 10e and rotating the transfer chain 10e according to the sales instruction, it is possible to push out the large goods stored in the goods storage column 2. .

As described above, according to the present invention, it is possible to prevent the rotation of the long and thin products in the longitudinal direction by pushing each product to the same position in the front or the rear from the two rows of goods formed by overlapping the goods in the front and rear directions. Therefore, the horizontal dimension of the goods transport device can be narrowed.

As a result, the vending machine can reliably take out goods and at the same time can store a large number of goods.
