Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product unloading device used in a vending machine for selling box-shaped products such as cigarettes.

[0002]

2. Description of the Related Art First, FIG. 22 shows a conventional structure of a product unloading device mounted on the above box-shaped product vending machine. In the figure, 1 is a cabinet of a vending machine, 2 is a product outlet opening at the front thereof, 3 is a product storage box housed in the cabinet 1 and 4 is a lower surface side of the product storage box 4. Box-shaped products such as cigarettes with pusher type bend mechanism 5
Are stacked and stored on the stage of the bend mechanism 4 side by side in two rows. Here, the pusher-type bend mechanism 4 includes a base 4a and a pusher 4 protruding from the stage upper surface of the base 4a.
b, Napier screw that feeds the pusher 4a forward and backward (cylindrical cam with endless spiral groove formed on outer peripheral surface)
4c, drive motor 4d, pusher position detection switch 4e
Etc.

The product unloading operation by the pusher type bending mechanism 4 is well known, and the products 5 stacked side by side are alternately moved back and forth from the product storage box 3 by alternately moving the pushers 4b back and forth for each sales command. They are alternately carried out and taken out through the shooter 6 to the product take-out port 2. Further, the product storage box 3 is provided with a sold-out detection switch 7, and its actuator 7a projects into the product storage box to detect the presence or absence of a product, and stops the sales when a sold-out signal is issued. .

[0004]

By the way, the conventional product unloading device adopting the pusher type bending mechanism has the following problems. 1) When the products 5 are stored in the product storage box 3 in two rows in the front and rear as shown in FIG. 22, the products 5 are carried out from the front and the back by the reciprocating motion of the pusher 4b. The product storage box 3 and the pusher type bend mechanism 4 are arranged in the center, and the product discharge passage 8 via the shooter 6 on the front and rear sides thereof.
Must be secured. That is, assuming that the front-rear dimension of the product storage box 3 is A and the width of the product discharge passage is B, the cabinet 1 of the vending machine has a depth dimension C of at least A + 2B.
Is required.

For this reason, the depth dimension of the cabinet becomes large, and this makes the vending machine thin (recently, the protrusion of the vending machine on the road is a social problem).
Will be a major obstacle to progress. 2) Further, even when the products 5 are stacked and stored in the product storage box 3 in a single row, it is necessary to secure an escape space behind the bend mechanism 4 in which the pusher 4b retracts behind the product storage box 3, There are limits to the thinning of vending machines.

3) From the operating principle of the pusher type bend mechanism 4, the products 5 are stored in the product storage box in three or more rows.
It is impossible to carry it out. 4) Since the pusher 4b is projected on the stage of the bend mechanism 4, when there is little remaining product stacked and stored in the product storage box 3, the storage posture of the product 5 on the pusher as the pusher retreats moves. It may collapse and tilt, and it may slip out of the product carry-out port of the product storage box and may be erroneously carried out. For this reason, conventionally, as shown in the figure, the actuator 7a of the sold-out detection switch 7 detects the presence or absence of the product in the third stage from the lower order, and a total of four products are overlapped by two in the front and rear rows (in this state, It is difficult to cause the collapse of the product storage posture due to the movement of the pusher), but the product sold-out signal is output, but this is disadvantageous because the number of products that can be sold is reduced accordingly.

5) The pusher-type bend mechanism 4 has a complicated pusher drive mechanism and a large external dimension, which occupies a large space in the refrigerator, which lowers the product storage efficiency. The present invention has been made in view of the above points, and an object thereof is to solve the above-mentioned problems and to reduce the thickness of a vending machine cabinet and to improve the product storage efficiency. The purpose of the present invention is to provide a product discharge device for a machine.

Equipped with.

[0019]

In the above structure, when the conveyors are started by a sales command while the products stored in the product storage boxes are stacked and placed on the horizontal conveyor, the products lined up at the bottom are conveyed to the front and the product storage boxes are transferred. It passes through the opening and is discharged. Further, even when the products are stored side by side in a plurality of rows in the front and rear rows in the product storage box, the products lined up in the rear row can be conveyed to the front by the conveyor like the products in the front row and can be carried out through the product outlet. Therefore, it is not necessary to secure a product unloading passage on the back side of the product storage box, and the depth dimension of the vending machine can be reduced by that amount to achieve a thin structure.

In addition, by arranging the number of belt conveyor mechanisms individually corresponding to the commodities stored in front and rear rows in the commodity storage box in front and rear series, and individually controlling each belt conveyor mechanism in accordance with the sales order of the commodities. It is possible to carry out products from each product line in a predetermined order. In this case, if a step is set between the belt conveyor mechanisms arranged in front and rear so that the belt surface of the rear row is slightly lower than the belt surface of the front row, the products conveyed on the belt from the rear row are The product does not hit the end face of the second row of products stacked in the front row, does not stop at that position, and goes under the bottom of the product and is conveyed to the front by the belt, which prevents the product jamming problem. Can be carried out in a predetermined order while maintaining a stable posture.

On the other hand, as a horizontal conveyor mechanism, a product storage box in which products are stacked and stored in front and rear rows is formed with a high step portion and a low step portion on the peripheral surface on the lower surface side according to the pitch of the product arrangement. With a structure that employs a belt-type or chain-type conveyor mechanism, the product unloading operation is performed as follows. That is, when the conveyor mechanism is started based on the sales command, the products placed on the high steps of the conveyor mechanism are temporarily stopped by receiving the braking force from the braking flapper mechanism provided at the product outlet, The product that has been placed on the lower stage is pushed out from the back while being pushed out of the braking flapper at the product exit, and is carried forward, and if the carry-out detection switch is activated during this carry-out operation, the conveyor is at that position. The mechanism is stopped to put the products on the lower stage in the standby position. In the process of this carry-out operation, since there is a slight step between the high step portion and the low step portion, the products on the low step portion sneak under the second lined product on the high step portion and It is transported so that the products lined up at the bottom are pushed out. Therefore, there is no possibility that the products in the front and rear rows will be bridged and cannot be carried out.

At the next sale, the product placed on the lower stage of the conveyor mechanism is pushed by the higher stage of the conveyor mechanism moving from the back and is carried out forward. Similarly, the placed products in the high-stage portion and the placed products in the low-stage portion are alternately carried out for each sales operation. When the product storage box runs out of stock and the product is sold out, the sold-out detection switch detects "no product" and outputs a sold-out signal.

Here, as a concrete embodiment of the chain type conveyor mechanism, a height adjusting adapter is attached to the low-stage chain segment so as to have the function of the high-stage chain segment. Thus, when the product to be sold is changed to a product having a large size or a small size, the length distribution of the high-stage portion and the low-stage region can be freely set according to the product size by using the adapter. Further, by making the chain segments mutually have a snap-fit connection structure, the chain segments can be connected by one-touch operation to easily assemble the endless chain. And, for each chain segment, a claw portion that prevents the shaft groove and the shaft portion from being separated from each other between adjacent segments,
Also, by providing the engaging step portion, there is no possibility of unexpected separation between the segments due to the tension of the chain even during the process in which the chain goes around the sprocket. Further, by forming a rearwardly inclined surface on the upper surface of the rear part of the chain segment for the high step portion, the step difference between the high step portion and the low step portion formed in the peripheral region of the chain becomes gentle. Therefore, it becomes possible to smoothly carry out the carried-out product while maintaining the horizontal posture. In addition to this, by forming a recess in the product extruding surface of the high-stage chain segment for the high-stage portion that is lined up at the beginning of the high-stage portion formed in the chain peripheral area,
When the high stepped part of the chain that wraps the products stacked in the back row in the product storage box wraps around from behind, the rear edge of the product fits into the above-mentioned recess, so that the product can be reliably transported forward. .

Further, the braking flapper mechanism provided at the product carry-out port applies a braking force to the product placed on the upper stage of the horizontal conveyor mechanism and waiting at the selling position, and is pushed out to the product in the rear row conveyed from the rear. It works to prevent being carried out by the frictional force working with the conveyor without waiting for the regular carrying-out operation. Then, by providing another short second flapper at the rear part of the braking flapper and configuring the braking flapper mechanism by the two flappers, the product carried out from the lower stage part of the horizontal conveyor mechanism has a rear end. Department is second
It is pressed from above by the flapper and passes through the product outlet while maintaining a substantially horizontal posture. In addition, the spring force of the second flapper decreases or does not act in the latter half of the opening when it is opened to some extent, so that the products carried on the upper stage of the conveyor mechanism can be carried out stably while maintaining a substantially horizontal posture. It As a result, it is possible to avoid a transport trouble such as a product jam at the product outlet due to an extreme inclination of the product on the way out.

Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIGS. 1 and 2 show an embodiment in which the products 5 are stored in the product storage box 3 side by side in two rows, and the product 5 is provided on the lower surface side of the product storage box 3 as a product discharge device. 2 horizontal belt conveyor mechanism 9 corresponding to the length size
A and 9B are arranged in series before and after. This belt conveyor mechanism is composed of an endless belt 9a stretched between pulleys and a drive motor 9b connected to the pulleys, and products 5 are stacked and placed in front and rear two rows on the upper surface of each belt 9a. Here, the belt conveyor mechanism 9 arranged in front and rear
A step h is set between A and 9B such that the belt surface in the rear row is slightly lower than the belt surface in the front row. Also,
A product outlet 3a through which one product 5 can pass is opened at the lower end of the front surface of the product storage box 3. Here, the opening height D of the product outlet 3a is D with the thickness of one product being d.
≈1.5d, and the above-mentioned step h is set to 0.5d or less. The belt conveyor mechanisms 9A and 9B are individually operated and stopped by commands from a control unit (not shown).

Next, with the above-described structure, the operation of carrying out the product will be described with reference to FIG.
This will be described with reference to (a) to (d). It should be noted that symbols # 1 to # 6 attached in the drawing represent the delivery order of the products 5. (A) The figure shows the standby state. Next, based on the sales instruction, when the belt conveyor mechanisms 9A and 9B are synchronously started in the direction of the arrow as shown in (b), the product # 1 is conveyed by the belt conveyor mechanism 9A in the front row by the belt and the product storage box 3 carries the products. It is carried out through the exit 3a. At the same time, the belt conveyor mechanism 9 in the rear row
The product # 2 on B is the step h between the belts described above.
With the setting of, the product is transferred underneath the product # 3 stacked in the front row and is transferred to the front belt conveyor mechanism 9A following the product # 1. Then, as shown in (c), the product # 1 falls downward from the front end of the belt conveyor mechanism 9A in a forward tilted posture, and the product # 2 moved from the rear row is placed on the belt conveyor mechanism 9A. One sale operation ends. Subsequently, in the second selling operation, as shown in FIG. 7D, only the belt conveyor mechanism 9A in the front row is rotated while the belt conveyor mechanism 9B in the rear row remains stopped. As a result, the product # 2 is carried forward through the product carry-out port 3a. Thereafter, by repeating the same operation as described above, the products from # 3 onward in the front and rear rows in the product storage box 3 are alternately carried out in a predetermined order for each sales operation.

The product storage box 3 shown in FIGS.
The product carry-out detection switch 10 and the sold-out detection switch 7 are provided in the arrangement as shown in FIG. That is, in FIG. 3, the carry-out detection switch 10 is provided in the upper front part of the product carry-out port 3a of the product storage box 3, and the swing actuator 10a thereof is arranged so as to be in a horizontal position at a free position. With such a structure, when the product 5 is started to slide forward while tilting forward from the front end of the belt conveyor mechanism 9A by the product discharge operation, the rear end of the product 5 flips up the actuator 10a and carries it out. When the detection switch 10 is temporarily turned on and then the product 5 drops downward, the actuator 10a returns to the standby position again, and the switch 10 returns to off. Therefore, the carry-out detection switch 10 is turned on and off when the product 5 is carried out.
The delivery of the product 5 can be accurately confirmed from the FF operation.

Further, in FIG. 4, the sold-out detection switch 7 is the same as the carry-out detection switch 10 described above, and the product outlet 3 is shown.
The oscillating actuator 7a is installed at the open end of a and stands by in a free position in a hanging posture. After confirming that the product 5 has been carried out by the carry-out detection switch 10 shown in FIG. 3, the actuator 7a of the sold-out detection switch 7 returns to the hanging posture and the switch 7 is turned off at this time.
When the product 5 is moved forward by turning the belt conveyor mechanism 9A for a short time, the product 5 pushes the actuator 7a and the sold-out detection switch 7 is turned on. Become. On the other hand, if there is no succeeding product, that is, if the product is sold out, the switch 7 continues to remain off even if the belt conveyor mechanism 9A is rotated. In this case, it is determined that the product is sold out. To do.

Next, FIG. 5 shows the control operation of the product delivery in combination with the delivery detection switch 10 and the sold-out detection switch 7.
The time charts of (a) and (b) will be described. First,
Fig. (A) shows the sales operation when there are at least two product inventories in the product storage box.
As described above, the belt conveyor mechanisms 9A and 9B are simultaneously started, and the carry-out detection switch 10 is temporarily turned off in the process.
When it becomes N and returns to OFF again, it is determined that the product # 1 has been carried out, the belt conveyor mechanisms 9A and 9B are once stopped, and then only the belt conveyor mechanism 9A in the front row is restarted for a short time, and the subsequent products. Sold out detection switch 7 with # 2
When is turned ON, the belt conveyor mechanism 9A is stopped to enter the sales standby state. Next, when the second sales command is given, only the belt conveyor mechanism 9A in the front row is rotated to carry out the product # 2, and similar control is performed from the operation signals of the carry-out detection switch 10 and the sold-out detection switch 7.

When the product storage box becomes empty and the product is sold out, the product is judged to be sold out after the following process. That is, as shown in FIG. 7B, when the belt conveyor mechanism 9A in the front row is rotated for a certain period of time and the belt conveyor mechanism 9B in the rear row is further rotated, the sold-out detection switch 7 is kept in the OFF state. It judges that there is no product and outputs a sold-out signal. Thereby, the last one of the products 5 stored in the product storage box 3 can be sold.

Embodiment 2 FIG. 6 shows an embodiment of a single-row sale specification, in which one belt conveyor mechanism 9 is arranged below the product storage box 3, and the product is placed on this belt conveyor. 5 are stacked and stored in a single row. With such a configuration, the belt conveyor mechanism 9 is operationally controlled for each sales command, and the products 5 are unloaded in order from the lowest order. Moreover,
Since there is no need for a pusher escape space behind the product storage box 3 unlike when using the pusher type bend mechanism,
The vending machine can be made thinner by that amount.

Example 3: FIG. 7 shows the product 5 in the product storage box 3.
FIG. 3 shows an embodiment of a three-row sales specification in which three belts are arranged side by side in a front-rear direction, and three belt conveyor mechanisms 9A, 9B, 9C are arranged in series below the product storage box 3, and A step h similar to that described in the first embodiment is set between the belt conveyor mechanisms.

In such a configuration, after being combined with the product carry-out detection switch 10 and the sold-out detection switch 7, FIG.
As shown in the time chart of No. 1, by controlling the operation of the belt conveyor mechanisms 9A to 9C in response to the first, second, and third sales commands, the products 5 arranged in the front and rear rows are # 1 ,.
It is possible to carry out and sell in the order of # 2, # 3, and thereafter, by repeating the sales operation according to this pattern,
You can sell without leaving the last one.

Fourth Embodiment: FIG. 9 shows an embodiment of a system different from the above-described embodiment for a product storage box 3 in which products 5 are arranged side by side in two rows. In this embodiment, one horizontal belt conveyor mechanism 9 is arranged below the product storage box 3, and the products 5 (# 1 to # 8) are stacked on the belt in front and rear rows. It is placed. Further, the endless belt 9a of the belt conveyor mechanism 9 stretched between the front and rear pulleys has its peripheral surface aligned with the arrangement of the commodities 5 arranged in the front and rear, and the peripheral surface along the longitudinal direction of the high step portion 9H and the low step portion 9L. It is divided into four zones so that and are lined up alternately. Here, the high step portion 9H and the low step portion 9L are formed by changing the thickness of the belt 9a, and the high step portion 9H
The height difference h similar to that of the first embodiment is set between the low step portion 9L and the low step portion 9L. The division band of the high step portion 9H and the low step portion 9L is set to be slightly longer than the length size of the product 5. The belt 9a is, for example, a rubber belt, and the belt surface of the high step portion 9H has a fine pitch in the width direction so that the high step portion 9H having a large thickness can freely bend around the pulley. The slit is engraved in a half-cut shape.

On the other hand, inside the belt conveyer mechanism 9, a carry-out detection switch 10 and a sold-out detection switch 7 are incorporated side by side, and the carry-out detection switch 1 is installed here.
The actuator 10a of No. 0 has its tip protruding forward of the product outlet 3a, and the actuator 7a of the sold-out detection switch 7 is spring-biased so that its tip projects to the lower surface side of the products 5 arranged in the rear row. Further, a skirt-shaped elastic braking piece 11 made of, for example, polyester resin, rubber or the like projects from above into the product unloading passage as a braking flapper that applies a braking force to the product 5 at the product unloading port 3a of the product storage box 3. It is installed as.

Next, the operation of unloading the product according to the above configuration will be described with reference to FIG.
This will be described with reference to (a) to (d). First, Fig. (A) shows a standby state for sale, and the products 5 stored in the product storage box 3 are
Among them, products # 1, # 3, # 5, # 7 lined up in the front row are lined up in the back row on the high step portion 9H of the belt conveyor mechanism 9.
2, # 4, # 6 and # 8 are placed on the lower step portion 9L so as to be slightly depressed as compared with the products in the front row. In addition, the sold-out detection switch 7 detects that the product 7 is present when the actuator 7a is pressed by the product # 2 (switch ON), and the actuator 10a of the carry-out detection switch 10 detects the product exit port 3a.
The switch is turned off by projecting forward.

When the belt conveyor mechanism 9 is started based on the first sale command from the sale standby state, the lowest products # 1 and # 2 placed on the high-stage part 9H and the low-stage part 9L. At the same time, the belt is conveyed forward. When the front end of the product # 1 hits the braking piece 11 during this transportation process, the product # 1
The braking action is added to prevent forward movement, and the vehicle temporarily stops at that position, but the following commodity # 2 on the low step portion 9L moves while being pushed by the high step portion 9H behind it. When coming, as shown in (b), Product # lined up on Product # 1
Commodity # 2 that sneaks under 3 pushes Commodity # 1 from behind. As a result, the product # 1 passes through the product delivery port 3a while pushing the braking piece 11 open, and then drops out from the front end of the conveyor mechanism 9 and is delivered to the product delivery port via a shooter (not shown). In addition, when the product is unloaded, the actuator 10a of the carry-out detection switch 10 moves to the product #
Since the switch is temporarily turned on and off by being pressed by 1, the belt conveyor mechanism 9 is stopped based on this switch signal, and one selling operation is completed. At the end of the sale, the product # 2 placed on the low step portion 9L is lined up at the lowest selling standby position in the front row, and the lowest product # 4 in the rear row is placed on the high step portion 9H.

Next, when the belt conveyor mechanism 9 is started by the second sales command, the product # 2 placed on the low-stage portion 9L and lined up in the sales standby position has moved from behind as shown in FIG. The product # 3 in the front row is pushed out by the high-step portion 9H, passes through the product unloading port 3a, and is carried out forward.
After being placed on L, the same storage state as in FIG. Less than,
By repeating the above-described operation for each sales command, the products # 3 to # 8 are carried out in a predetermined order. Then, when the product # 7 is carried out by the seventh sales command, the last product # 8 moves from the rear row to the sales standby position in the front row as shown in (d) and the rear row of the product storage box 3 becomes empty. So
As a result, the sold-out detection switch 7 deactivates the actuator 7a, detects "no product", and outputs a sold-out signal. FIG. 10 is a time chart showing the above-described product unloading operation.

In the illustrated example, in order to make sure that the brand of the product is correct when replenishing the product, one product 5 is placed in the product storage box 3.
The sold-out detection switch 7 is installed at a position facing the product in the rear row so as to output the sold-out signal in the state where the sold-out pieces are left, but it is necessary to install the sold-out detection switch 7 so as to detect the products arranged in the front row. For example, the last one can be sold without leaving the product inventory in the product storage box 3.

Embodiment 5: In FIGS. 11A and 11B, a chain conveyor mechanism 12 is adopted as a horizontal conveyor of a product unloading device, instead of the belt conveyor mechanism 9 in the fourth embodiment. That is, the chain conveyor mechanism 12 is constructed by assembling a commodity conveying chain 14 stretched between a pair of front and rear sprockets 13 and a drive motor 16 connected to the sprockets 13 via gears 15. The same sold-out detection switch 7 and carry-out detection switch 10 as in the fourth embodiment are incorporated. In addition, an elastic braking piece 11 is provided as a braking flapper at the product outlet 3a of the product storage box 3.

Here, the chain 14 is formed by connecting a large number of chain segments made as resin molded products, and the upper surface of the chain segment is the product 5
Like the belt conveyor mechanism described in the fourth embodiment, as a mounting surface, the step h is set in the circumferential region of the chain 14 by adjusting the pitch to the length size of the products 5 stacked in front and rear rows and mounting the products. 14H and low stepped portion 14L
The division zones are alternately formed.

Next, FIG. 12 shows a concrete structure of a chain segment constituting the chain 14. That is,
The high-step portion 14H of the chain 14 is made up of a connected body of the tall high-step portion chain segments (segment height A) 14a shown in FIGS. 12 (a) and 12 (b), and the low-step portion 14L is shown in FIG.
2 (a) and (c), which is composed of a connecting body of the low chain chain segment 14b (segment height B) for the low section,
Moreover, the front and rear ends of both are connected to each other to form the endless chain 14. Here, each chain segment 14a, 14b is a pair of left and right link plates 14
c and the shaft part 14d connecting between the link plate 14c
And a chain roller portion 14e that meshes with the sprocket 13 are integrally formed, and a shaft groove 14f opened to the lower surface side is formed in a portion projecting to the rear end side of the link plate 14c. As shown in (d), the shaft groove 14f is fitted and connected to the shaft portion 14d of the adjacent chain segment by a one-touch operation in a snap fit manner from above.

The operation of the product unloading device which employs the chain conveyor mechanism 12 having such a configuration is exactly the same as the selling operation of the above-mentioned fourth embodiment, and the products 5 stacked and stored in the product storage box 3 are divided into front and rear two rows. 1 for each sales action in the given order
The products can be carried forward one by one through the product carry-out port 3a of the product storage box 3. In addition, in the low-stage chain segment 14b of FIG. 12 (c), an adapter 15 for height adjustment set to a thickness C (C = AB) is combined as necessary, and the bottom surface of the adapter 15 is attached. The provided connecting pin 15a is inserted into a pin hole 14g formed in the upper surface of the link plate 14c of the chain segment 14b to be used as a high-stage chain segment of height A. That is, the high step portion 14 originally set in the peripheral region of the chain 14
H, if the sale item 5 is changed to a short and small size item having an extremely short length while keeping the low step portion 14L, unnecessary play is generated in the area of the low step portion 14L, and the delivery operation of the item is unstable. Becomes Therefore, in this case, the above-mentioned adapter 15 is attached to the upper surface of the chain segment 14b of the low step portion 14L in accordance with the length size of the product to be sold so as to fill the above-mentioned play, so that the product carrying-out operation is stabilized. Further, by mounting the adapter 15 so as to fill the entire length of the low step portion 14L and aligning the circumferential surface of the chain 14 with the same height as the high step portion 14H, a long size product 5 can be obtained in the same manner as described in FIG. It is also possible to sell in a single row.

Next, the above-mentioned chain segment 14
FIG. 13 shows an embodiment in which the structures of a and 14b are improved. That is, in the chain segment shown in FIG. 12, the open end of the shaft groove 14f is worn during long-term use, and is likely to come off from the shaft part 14d of the adjacent chain segment. Especially in the peripheral region of the sprocket 13, the radial component of the tension applied to the chain 14 is applied to the shaft portion 14d.
And the connecting groove 14f, the connection between the two may be broken and the chain may be broken. Therefore, in order to prevent such trouble, as shown in FIG. 13A, a claw portion 14h protruding rearward from the rear end of the link plate 14c is provided, and the claw portion is provided between adjacent chain segments. An engagement step 14i is formed on the wall surface of the link plate facing 14h. The claw portion 14h and the engagement step portion 14i are similarly provided in the low-stage chain segment 14b.

As a result, as shown in FIG. 13 (b),
In the process in which the chain 14 revolves around the circumference of a sprocket (not shown), the claw portions 14h are engaged with the engaging stepped portions 14i of the adjacent chain segments 14a to move the shaft portion 14d between the chain segments 14a. A force that holds the shaft groove 14f in the groove acts to prevent the chain segments from being disconnected from each other.

Further, in FIG. 13 (a), in the high-stage chain 14a, an inclined surface 14j which is inclined backward is formed on the upper surface of the rear portion of the link plate 14c. As a result, the following effects can be obtained. That is, chain 1
When the link plate 14c having the structure in which the inclined surface 14j is not formed (see FIG. 12) is adopted as the high-stage chain segment 14a of FIG. 4, the state of the product unloading operation as shown in FIG. 4 (state corresponding to FIG. 9 (b)), the chain segment 14a arranged in the last row of the high step portion and the chain segment 14 arranged in the front row of the low step portion
Due to the steep step between the product and the item b, the product # 1 on the unloading side will be carried out with the tip of the product being lifted up. 5 may be caught and cause a bridge carry-out problem. In this regard, if the chain segment 14a with the inclined surface 14j shown in FIG. 13A is adopted, as shown in FIG.
While being guided by the rearwardly inclined surface 14j of the chain segment 14a, it moves forward while maintaining a substantially horizontal posture, and when it is disengaged from the chain 14, the tip changes downward and falls to a vertical posture. As a result, the product 5 can be smoothly carried out to the product take-out port without carrying-out trouble such as being caught in the drop-out carrying-out path. It should be noted that similar effects can be obtained even if such a rearwardly inclined surface 14j is formed at the boundary where the belt conveyor mechanism 9 shown in FIG. 9 transitions from the high step portion 9H to the low step portion 9L.

Further, FIG. 15A shows an embodiment of the chain segment with another improvement. That is, in the case where the chain conveyor mechanism 12 is configured by adopting the above-described structure for the high-stage chain segment 14a,
As shown in FIG. 5 (b), the chain segment lined up at the head of the chain high-step portion 14H that wraps around the sprocket on the lower surface of the lowest product # 2 in the rear row vertically stacked in the product storage box 3 in a backward tilted posture. 14a may slip into and slip, and this may cause a transport trouble such that the product # 2 cannot be sent forward. Therefore, as shown in FIG. 15A, with respect to the chain segment 14a lined up at the head of the high step portion 14H, a concave portion 14k is formed on the product extrusion surface on the front surface thereof.
By forming the above, the recessed portion 14 of the chain segment 14 in which the rear end of the product # 2 has come to wrap around from the rear is formed.
Since it enters k, the product # 1 in the front row can be carried out while reliably sending the product forward by the high step portion 14H. Next, another embodiment of the braking flapper mechanism installed at the product outlet 3a of the product storage box 3 different from the elastic braking piece 11 shown in FIGS. 9 and 11 will be described with reference to FIGS.

First, in the embodiment shown in FIG. 16, a plate-like flapper 17 is hung so that its upper end is pivotally supported by a gate 16 installed at a product carry-out port 3a of a product storage box 3 so as to project into a product carry-out passage. A braking flapper mechanism is constituted by a braking spring 18 (a twisting coil spring provided on a support shaft of the flapper 17) that applies a braking force by urging the flapper 17 in the closing direction. Here, the function of the flapper 17 is the same as that of the elastic braking piece 11 described in FIG. 9, and the braking force is applied to the product # 1 that is carried out on the high step portion of the conveyor mechanism 12 to apply the product # 1 in the rear row.
It functions to keep the product # 1 inside the product carry-out port until it is forcedly pushed out by 2.

FIG. 17 shows an embodiment in which the braking flapper mechanism is composed of two flappers by modifying FIG. In this embodiment, in addition to the structure of FIG. 16, a flexible elastic braking piece 11 is provided behind the flapper 17. Here, the elastic braking piece 11 is shorter and smaller than the flapper 17, and the sheet 5 is provided between the tip of the elastic braking piece 11 and the lower step portion of the conveyor mechanism 12.
It has a gap that can be worn through and works as follows. That is, when the product 5 carried on the lower stage of the conveyor mechanism 12 pushes open the flapper 17 and passes through the product carry-out port, the rear part of the product is pressed from above and held in a horizontal posture to carry out the carry-out operation. In the latter half of the second half, the product 5 in the rear row sneaks into the position where the product 5 leans forward as shown by the chain line, and serves to prevent the carry-out trouble of bridging with the gate 16. Further, with respect to the product carried out on the high step portion of the conveyor mechanism 12, the elastic braking piece 11 cooperates with the flapper 17 to apply an appropriate braking force, and the product in the rear row is forcedly pushed. Until the conveyor mechanism 1
It functions to slip on 2 and hold it in the standby position, after which it is pushed forward by the commodity 5 together with the flapper 17 and opens forward.

In the embodiment shown in FIGS. 18A and 18B, the elastic braking piece 11 in FIG. 17 is replaced with another flapper, and each gate 16 is provided with a braking spring individually. First flapper 17 and second flapper 19
And are arranged side by side so that they can work together. Here, similarly to the elastic braking piece 11 in FIG. 17, the second flapper 19 has a shorter protruding length to the product unloading passage than the first flapper 17, and the tip end thereof and the low step portion of the conveyor mechanism 12 are the same. A gap is set between them so that the product 5 can be worn through. Further, as shown in FIG. 18B, a fan-shaped cam portion 19a centering on the flapper support shaft is formed at the upper end of the second flapper 19, and a braking spring (leaf spring) 20 is formed on the cam surface. It is assembled to hit.
In order to understand the assembly structure of FIG.
9 is an exploded perspective view of the control flapper mechanism.

In the above construction, the second flapper 19 is similar to the elastic braking piece 11 described in FIG.
When the product 5 carried on the lower step of 2 passes through the product outlet, it functions to hold the rear part of the product from above and maintain a horizontal posture, and further to the second flapper 19 as follows. The spring braking force like the above is applied.
That is, when the product 5 is carried on the high step portion of the conveyor mechanism 12 (see FIG. 9B), the control spring 20 is in the initial stage where the second flapper 19 starts to open from the closed state.
Is brought into contact with the upper surface of the fan-shaped cam portion 19a to apply a braking force to the flapper 19, and in cooperation with the spring braking force applied to the first flapper 17, the product 5 waiting in the front row is conveyed by the conveyor mechanism 1
Slip to 2 and stop inside gate 16.

On the other hand, when the product 5 placed on the high step portion of the conveyor mechanism 12 and abutting against the second flapper 19 is forcedly pushed by the conveyance of the product in the rear row placed on the low step portion and is opened to a certain extent, Since the force point of the braking spring 20 on the cam portion 19a moves from the upper surface of the cam portion 19a to the circumferential surface of the fan,
The spring braking force applied to the flapper 19 sharply decreases and weakens the restraining force applied to the product 5 being conveyed. As a result, the following carry-out trouble can be prevented for the product 5 carried out from the high-stage side of the conveyor mechanism 12. That is, product 5
When the second flapper 19 keeps pressing the product 5 with a strong spring force while the product passes through the product carry-out port, the carried-out product 5 cannot freely fall forward from the front end of the conveyor mechanism 12, and the Is restrained in a forward leaning posture with the contact point of as a fulcrum, and the head of the rear row product placed on the low step portion and conveyed from behind cuts in here and the product 5 is sandwiched between the gate 16 and the bridge. However, as described above, the spring force of the second flapper 19 is suddenly reduced during the release to weaken the restraining force that holds down the product 5 in the process of being discharged. The flappers 17 and 19 can be rubbed through without receiving a large braking force, and the occurrence of the product bridge described above can be prevented. As a result, the product 5 falls freely from the front end of the conveyor mechanism 12 and can be carried out without trouble.

When the product 5 comes out of the braking flapper mechanism, the first flapper 17 returns to its original position by the spring force of the braking spring 18, and the first flapper 17 moves along this returning path.
Pushes back the second flapper 19 (the second flapper itself has no restoring force in the open state). As a result, the second flapper 19 returns to the original position together with the first flapper 17, and at the same time the braking spring 2 that acts on the second flapper 19
The force point of 0 shifts from the peripheral surface of the fan-shaped cam portion 19a to the upper surface and returns to the initial state.

That is, in this embodiment, the conveyor mechanism 1
The second flapper 19 functions to hold the carried-out product in a horizontal posture for the product carried out on the lower stepped portion of the second step, and to the product carried out on the higher stepped section, While the first flapper 17 and the second flapper 19 share the initial sufficient braking force on the product, when the flapper is pushed open by the product, the spring braking force of the second flapper 19 is reduced and the product is commercialized. The second flapper 19 can be returned to the standby position together with the first flapper by using the spring force of the braking spring 18 attached to the first flapper 17 after preventing the bridging to the carry-out port.

Next, application examples in which the structure of FIG. 18 is further improved are shown in FIGS. In this embodiment, of the two front and rear first flappers 17 and second flappers 19 provided on the gate 16, the second flapper 19 is a link 22 pivotally supported by the gate 16 via a support shaft 21. Is connected to a tip end of the second spring 19 together with a braking spring (torsion coil spring) 18 through a support shaft 23, and a stopper pin 24 is provided on the gate 16 side so as to face the front surface of the top of the second flapper 19. There is. The stopper pin 24 is loosely fitted over the elongated holes 16b formed in the left and right side walls of the gate cover 16a and laid over it.

With such a structure, in the standby state shown in FIG. 20 (a), the stopper pin 24 has its own weight so as to have the elongated hole 16b.
The link 22 connected to the second flapper 19 is restrained so as not to tilt forward.
In this state, when the product is unloaded from the high-stage side of the conveyor mechanism by the selling operation, the flapper 1 is initially loaded at the beginning of the unloading operation.
A large spring braking force by the braking spring 20 is applied to 9 to prevent the product from being pushed out due to friction with the chain.
Then, as described in FIG. 9B, when the products in the rear row placed on the lower stage of the conveyor mechanism forcibly push the products in the front row forward, as shown in FIG. At the same time, the second flapper 19 starts to open against the braking spring 20, and when the flapper 19 opens to some extent, the stopper pin 24 is pushed upward in the elongated hole 16b to release the constraint of the flapper 19. In this state, FIG. 20 (c)
As shown by, the second flapper 19 becomes free to rotate integrally with the link 22 about the support shaft 21 as a fulcrum, and at the same time, the braking spring 20 returns and the spring braking force applied to the second flapper 19 disappears. As a result, similarly to the braking flapper mechanism of FIG. 18, the function of preventing the carry-out trouble such as product jamming due to the pressing of the second flapper 19 is further ensured.
In addition, when the product 5 is unloaded, the second flapper 19 moves to the first
Together with the flapper 17, the spring force of the braking spring 18 returns to the standby position where the braking spring 18 hangs down, and at the same time, the stopper pin 24 also returns to its original position to hold the second flapper 19 and the link 22 in the standby state.

The vending machine is not limited to selling cigarettes, and can of course be applied to selling box-shaped products other than cigarettes.
