Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a combination of a conveyor type shelving mechanism for storing products and an elevator bucket, and the products dispensed from the conveyor shelving mechanism based on a sales command are passed through the buckets. The present invention relates to a vending machine equipped with a conveyor-type product shelf that is carried out to a product outlet.

[Conventional technology]

First, an outline of an automatic vending machine equipped with a conveyor type product shelf to which the present invention is applied will be described with reference to FIGS. 6 and 7. In the figure, 1 is a vending machine cabinet, 2,
Reference numeral 3 denotes a front door and an inner door provided on the front surface of the cabinet 1, and 4 denotes a product outlet opening at the bottom of the front door. The cabinet 1 has a plurality of upper and lower conveyor shelves for loading and storing various products. A bucket 5 for transporting products, which is connected to the mechanism 5, the upper and lower conveyor-type shelving units 5 and the product outlet 4, and is operated to move up and down like an elevator, is provided. A product outlet 3a communicates with a product outlet 4 opened in the inner door.

Here, the conveyor type shelving mechanism 5 is configured such that the commodity 7 is mounted on a horizontally moving type conveyor shelving mechanism which is moved and operated by the bend motor 51 in the arrow P direction. On the other hand, the bucket 6 is formed as a U-shaped box body having an open front surface as clearly shown in FIG. 7, and is of an elevator mechanism laid between upper and lower sprockets 8 along a bucket ascending / descending path indicated by an arrow Q. Pin 62 on lifter 61 connected to chain 9
It is supported so that it can be tilted forward through. Reference numeral 10 is a drive motor connected to the sprocket 8 of the elevator mechanism, 11 is a tilting posture control member of the bucket installed at the lower end of the ascending / descending path facing the bottom plate of the bucket 6, and 12 is a product unloading shooter communicating with the product outlet 4. Is.

With such a configuration, the products 7 are placed and stored on the conveyor-type shelving mechanism 5 at the upper and lower stages, and in the conventional vending machine, the bucket 6 is at the lowest standby position when waiting for sale, and the top plate thereof is provided. Seals the bucket ascending / descending path leading from the product take-out port 4 to the shelving mechanism in the warehouse to perform the anti-theft function. here,
When a sales command is given, the bucket 6 first moves up to the position of the conveyor type shelf mechanism 5 for the product designated by the product selection and stops at the side position of the shelf. Next, the products dispensed from the designated conveyor rack mechanism 5 are buckets 6.
When it is delivered to the bucket 6, the bucket 6 descends together with the chain 9 by the drive motor 10 and reaches the lowest position thereof and tilts forward as shown in FIG. Then, it is carried out to the product outlet 4 through the product outlet 3a.

By the way, as described above, in order to prevent the goods stored in the warehouse from being illegally stolen from the goods outlet 4 at the time of sale standby, the bucket 6 is made to stand by at the lowest product carrying-out position, and the conveyor designated by the sales command has the bucket. The product is lifted up to the formula rack mechanism 5 to receive the product, and then the product take-out port 4 again.
In the operation of lowering to carry out the goods, the time required for one sale including the time required for the reciprocating motion of the bucket 6 is long, and the customer's holding time is accordingly prolonged.

On the other hand, when the product stored in the conveyor rack mechanism at the bottom is unloaded, the bucket 6 slightly moves up to a horizontal position, and after receiving the product, it descends slightly to an inclined horizontal position and the product is unloaded. Therefore, the product will be sold in the shortest time. Therefore, in the configuration in which the bucket is kept in the lowest position, the product sales time fluctuates considerably depending on the height position of the conveyor shelf mechanism, which fluctuates the customers. Customers will feel even more uncomfortable as it takes longer to sell.

From this point of view, a system in which a bucket is made to stand by in the upper part of the refrigerator has been proposed by the same applicant in Japanese Patent Application No. 60-107821.

In this method, by holding the bucket at the top, when moving the goods carried out from the upper, middle, and lower conveyor rack mechanisms to the product take-out port by the bucket, the moving distance of the bucket with respect to each conveyor rack mechanism is changed. It is possible to equalize, so it becomes possible to sell each product at about the same selling time, and when selling the products stored in the conveyor rack mechanism of the highest level, compared to the one that put the bucket at the lowest standby,
The travel distance of the bucket is halved, and therefore the sales time can be cut in half.

In addition, in this method, the product outlet 4 and the conveyor shelf mechanism 5 in the warehouse can freely communicate with each other through the ascending / descending path of the bucket 6 unless the product outlet 4 is specially blocked while waiting for sale. It is possible to illegally steal products by inserting hands etc. from the outlet.

Therefore, in the above proposal, in addition to the structure in which the bucket stands by at the upper position in the warehouse, an opening / closing door that is locked by an electromagnetic solenoid is installed at the product outlet, and the door is locked at the closed position while waiting for sale. When the sale operation moves the bucket down to the unloading position and the product is unloaded, the electromagnetic solenoid lock is released by the operation signal of the product unloading switch, and the customer manually opens the door to release the product. I am able to take it out freely.

[Problems to be solved by the device]

By the way, the above-mentioned proposal has the following inconvenience because a door that is locked during standby for theft prevention is provided at the product outlet.

In other words, the anti-theft door, that is, the anti-theft door is exposed at the front of the product outlet, and the anti-theft door usually needs to be made of transparent plastic so that the product can be carried out. The rigidity cannot be increased so much.
Therefore, there is a risk that it may cause mischief and the anti-theft door may be easily destroyed. Moreover, even if it is not intentional,
Vending machines are often provided with a dustproof door that can be freely opened and closed by the customer at the product outlet, and since it is indistinguishable from the appearance of this dustproof door, the customer mistakenly thinks it can be opened at any time. However, there are times when people try to forcibly open a locked anti-theft door, which causes damage, and even if it does not cause damage, it makes customers feel uncomfortable.

Therefore, this invention provides a vending machine with a bucket at the top so that all the products can be sold at the same time without variation in sales time, and the anti-theft property is further improved and reliability is improved. The purpose is to do.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention has a plurality of upper and lower conveyor type shelving mechanisms arranged in a cabinet cabinet equipped with a front door and a double door of an inner door, and each conveyor type shelving mechanism and the front surface. Combining a product transport bucket that is linked to a product outlet that opens at the bottom of the door and that is lifted and lowered by an elevator mechanism, delivers the product dispensed from the conveyor-type shelving mechanism to the bucket in response to a sales command, and also transfers the bucket to the product. In a vending machine that descends to the carry-out position and carries out to the product outlet of the front door through the product outlet of the inner door, the standby position of the bucket when waiting for sale is set to the upper part of the warehouse and the product of the inner door An anti-theft door that opens and closes the exit is provided on the back side of the product exit, and the anti-theft door and the drive motor for bucket lifting operation are connected to each other to prevent the anti-theft door from being sold. While restrained in the closed state of the goods outlet opening with the operation of lowering the product unloading position of the bucket, and closes with the operation of increasing the standby position of the bucket shall be provided a cam-type control mechanism having a configuration.

[Action]

By setting the standby position of the bucket at the top of the warehouse,
The moving distance of the bucket becomes equal to the conveyor rack mechanism of each stage, and each product can be sold at the same time. Also, since the anti-theft door is provided on the back side of the product exit of the inner door, it cannot be seen normally from the customer's position, and since the anti-theft door is located at the back of the product exit, it is not necessary to make it transparent. Since it is possible to use a manufactured product, the inside of the refrigerator is shielded and the rigidity is increased, and as a result, it does not induce mischief and is difficult to break. Moreover, since the anti-theft door is opened and closed by the bucket lifting drive motor via the cam type control mechanism, a new drive source for opening and closing the anti-theft door is not required.

〔Example〕

1 to 5 show an embodiment of the present invention, and the same members corresponding to FIG. 7 are designated by the same reference numerals. First, in FIG. 1, the elevator mechanism for lifting and lowering the bucket 6 is moved so as to move to the back side of the product outlet of the inner door 3 and open and close the product outlet 3a at the lower end of the bucket ascending / descending path inside the refrigerator. An antitheft device 14 equipped with an antitheft door 13 that opens and closes in conjunction is installed. Here, the bucket 6 is in the standby position at the highest position in the store as shown in the drawing in the sales standby state, and the anti-theft door 13 is locked and restrained at the position where the product outlet 3a is closed as shown by the solid line in the figure. Therefore, in this state, it is not possible to insert a hand or the like into the refrigerator from the product outlet 4. On the other hand, when the bucket 6 receives the product from the conveyor type shelving mechanism 5 by the regular sale operation and then descends to the product unloading position facing the product outlet 4, the elevator mechanism, particularly the chain drive motor 1 thereof.
The lock of the anti-theft door 13 is released in conjunction with the rotation of 0, and the door automatically opens. Therefore, the product is unloaded from the bucket 6 to the product outlet 4 via the shooter 12 and the product outlet 3a, at which point the customer can freely take out the product. When the customer picks up the product from the product outlet 4, the bucket 6 is raised so that the elevator mechanism returns to the standby state upon detection of the product, and the anti-theft door 13 is rotated to the closed position again. And lock and lock in this position.

Next, the detailed structure of the anti-theft device 14 will be described with reference to FIGS. 2 and 3, the above-mentioned anti-theft door 1
3 is an assembly of left and right fan-shaped side plates 15 and arcuate wall plates 16 extending between the side plates, and is swingably supported by a frame 18 of the antitheft device via a support shaft 17. One end of a swing arm 19 is coupled to the left and right side plates of the anti-theft door 13, and the other end is pivotally supported by a support base 21 via an intermediate lever 20. A roller shaft 22 connecting the arm 19 and the lever 20 is provided with a roller 23 that comes into contact with the cam of the cam type control mechanism described below.
That is, a cam shaft 24 is installed in parallel with the roller shaft 22, and a main cam 25 and an auxiliary cam 26 are provided on the shaft so as to come into contact with the rollers 23. This cam type control mechanism also serves as a restraint means and an opening / closing means for the anti-theft door 13, and its detailed structure will be described later with reference to FIGS. 4 and 5. Further, one end of the cam shaft 24 projects laterally of the frame 18 and is conductively coupled to a small-diameter sprocket 30 attached to a drive shaft 29 of the drive motor 10 via a large-diameter sprocket 27 and a chain 28. The drive shaft 29
A chain 9 for raising and lowering the bucket is connected to a sprocket 8 attached at an intermediate position on the shaft.

Next, the detailed structure of the cam type control mechanism will be described with reference to FIGS. 4 and 5, while the main cam 25 is fixedly connected to the cam shaft 24, while the auxiliary cam 26 is connected to the cam shaft 2.
4 is loosely fitted and supported, and is conductively connected to the cam shaft 24 via a reduction gear mechanism in which gears 31 to 34 are combined.
On the other hand, in the cam shape of the main cam 25, as shown in FIG. 5, a notch portion into which the roller 23 is dropped is opened at one position on the circumference of the disk. Similarly, the auxiliary cam 26 is formed such that a cut portion wider than the cut portion of the main cam 25 is opened on the circumference of the disk. Further, the relationship between the transmission ratio between the sprocket 8 and the sprockets 27 and 30 and the reduction ratio of the reduction gear mechanism provided on the camshaft 24 is selected as follows. That is, while the bucket 6 in FIG. 1 descends from the uppermost standby position to the lowermost product unloading position, the camshaft 24, and hence the main cam 25 directly connected to the camshaft 24, makes 3.5 revolutions, during which the auxiliary cam 26 Is selected to make one rotation, and the relative positions of the main cam 25 and the auxiliary cam 26 are such that the notch openings facing the roller 23 overlap each other only when the bucket 6 reaches the lowest position. Is set. An actuator 36 of a product detection switch 35 that detects the presence or absence of a product is provided on the upper surface of the tutor 12 described above.

The operation of the anti-theft device 14 having such a structure proceeds as follows. That is, FIGS. 2 and 3 show a state in which the anti-theft door 13 is opened, and the roller 23 connected to the swing arm 19 of the anti-theft door 13 is formed in the overlapping cut opening of the main cam 25 and the auxiliary cam 26. Depressed, the anti-theft door 13 has a spindle 17
It hangs by its own weight and is opened to the position shown by the solid line in FIG. Further, in this state, although not shown, the bucket 6 (see FIG. 1) is located at the commodity carry-out position so as to enter the inside of the fan-shaped side plate 15 of the anti-theft door 13.

Drive motor 1 to return to the sales standby state from here
When 0 drives the drive shaft 29 to rotate clockwise in FIG. 2,
At the same time as the bucket 6 is raised toward the standby position via the sprocket 8 and the chain 9, the cam shaft 2
4, the main cam 25 and the auxiliary cam 26 are rotated clockwise. As a result, the roller 23 is pushed out circumferentially along the cam surface of the main cam 25 from the notch opening, and the anti-theft plate 13 is directed from the solid line to the closed position indicated by the chain line via the swing arm 19 which follows this movement. It is pushed up around the support shaft 17 and rotated, and here the product outlet 3a is closed from the inside by the arc-shaped wall plate 16. Therefore, in this closed state, it is impossible to insert a hand or the like into the inside of the machine through the product outlet 4, and it is impossible to open the anti-theft door 13 from the outside.

On the other hand, when the selling operation is started by a command from the above-mentioned sales standby state and the bucket 6 is started to descend by the drive of the drive motor 10 in this process, the main shaft 25 and the auxiliary cam 26 are interlocked with the cam shaft 24 in conjunction with this. Start rotating counterclockwise. However, as described above, the rotation ratios of the main cam 25 and the auxiliary cam 26 are different, and the notch openings of both cams coincide only when the bucket 6 reaches the lowest product unloading position, and In the middle of the downward movement of the bucket 6, the anti-theft door 13 is connected to the cam 23 by the roller 23 connected to the door.
It is held in the closed position by being restrained by the peripheral surfaces of 5, 26. Then, at the same time that the bucket 6 carrying the product descends to the lowest position, the notch openings of the main cam 25 and the auxiliary cam 26 facing the roller 23 coincide with each other, and the roller 23 falls into the notch opening. It rotates by its own weight from the position shown by the chain line in FIG. 2 to the position shown by the solid line to open the product outlet 3a. As a result, the product stored in the bucket 6 is carried out to the product take-out port 4 via the shooter 12, and at the same time, the product detection switch 35 mounted on the shooter 12 is activated by the weight of the carried product to detect the carry-out of the product. Here, when the customer takes out the carried-out product from the product outlet 4, the product detection switch 35 is restored, and the drive motor 10 is restarted based on this signal to raise the bucket 6 toward the standby position. At the same time, as described above, the anti-theft door 13 is pushed up again to the closed position and restrained at this position.

[Effect of device]

As described above, according to the present invention, the standby position of the bucket at the time of sale standby is set at the upper part of the inside of the warehouse, and the anti-theft door for opening and closing the product outlet of the inner door is provided at the back side of the product outlet. At the same time, the anti-theft door and the drive motor for lifting and lowering the bucket are connected to each other, and the anti-theft door is held in the standby state with the product outlet closed, and is opened as the bucket descends to the product carry-out position. In addition, by providing a cam type control mechanism with a configuration that closes when the bucket moves up to the standby position, it is possible to sell all the products at the same time without variation in the sales time, and to open and close the anti-theft door. It is possible to provide a highly reliable vending machine having sufficient anti-theft property without providing a new drive source.
