[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of products having a circular cross section, which are stored in a so-called slant-shelf type product passage inclined rearward in a line in the front-rear direction.
The present invention relates to a product dispensing device for an automatic vending machine, which dispenses one by one from the last item at the time of sale.

[0002]

2. Description of the Related Art As a conventional product dispensing device of this type, for example, one shown in FIG. 11 is known. This product delivery device includes a first ejector c1 for locking the last-placed product S1 (sales product) of the many products S stored in the product passage b in the product rack a, and the next-most product. Product S2
The second ejector c2 for locking (the next sale product) is provided. The front end of the first ejector c1 has a product passage b.
Is rotatably supported by a lower shaft d1, and the rear end of the second ejector c2 is rotatably supported by the shaft d2.
Both c1 and c2 are configured to be able to appear and disappear in the product passage b.

Both ejectors c1 and c2 are normally provided with a spring and an interlocking mechanism (not shown) at a position where the former c1 protrudes into the product passage b as shown by a solid line in FIG.
The latter c2 is held at a position retracted from the product passage b. When the product S is loaded from the product insertion port on the front side (not shown) at the time of loading the product S, the next sale product S1
Are received by the first ejector c1, so that a large number of products S are stored in a line in the product passage b. At the time of sale, as the drive mechanism (not shown) is actuated, the second ejector c2 projects into the product passage b and locks the next sale product S2, as shown by the chain double-dashed line in FIG. The first ejector c1 retracts from the product passage b due to the weight of S1 so that the sale product S1 is dispensed from the drop passage e. Next, the drive mechanism causes the first ejector c1 to project into the product passage b as shown by the solid line, and then the second ejector c2 is connected to the product passage b.
By evacuating from, the next sale product S2 is received by the first ejector c1 from diagonally below and becomes the next sale product.

A passage width regulating plate e is provided above the product passage b. This passage width regulating plate e is
By guiding the pins f, f of the book with a pair of guide grooves g1, g2 formed in the product rack a, they are attached so as to be movable in the vertical direction, and the width of the product passage b is shown in FIG. The setting can be switched between two steps, that is, the setting for the large-diameter product S and the setting for the small-diameter product W shown in (b). With this configuration, when the small-diameter product W is stored, the next-sales product W2 is prevented from accidentally passing over the second ejector c2. The passage width regulating plate e is linked to an operation plate (not shown) on the side of the product inlet, and the passage width regulating plate e is switched by moving the operation plate by an operator or the like.

[0005]

In the above-described conventional product dispensing device, since a large number of products S are stored in a state in which they are in contact with each other in the product passage b inclined obliquely downward, the last-placed product S1 is locked. The weight of a large number of products S is cumulatively added to the first ejector c1. On the other hand, the first ejector c1
Comes into contact with the product S1 to be sold in a state of projecting obliquely rearward into the product passage b, and thus is prone to fall backward. Therefore, even if the spring force of the spring is applied, the weight of a large number of products S or the input of products S is introduced. There is a case where the product S cannot be withstood against the dynamic load at that time and is fallen backward, so that the product S is erroneously dispensed. Further, there is a drawback that the structure becomes complicated because the passage width regulating plate e and the operation plate linked to the passage width regulating plate e are required to switch the passage width of the product passage b.

The present invention has been made in order to solve such a problem, and is an automatic vending machine having a so-called slant shelf type product passage, which has a relatively simple structure and can be used to store large and small products in a standby state. An object of the present invention is to provide a product dispensing device for a vending machine that can be surely held.

[0007]

In order to achieve this object, the present invention provides a plurality of products arranged in a front-rear direction in a product passage defined by a bottom plate and both side plates and inclined downward to the rear. A product dispenser for a vending machine that dispenses the last-order product from a product storage rack to be stored, and has a locking bar portion and a pair of legs extending from both ends thereof, and these legs are provided on both sides plate portions of the commodity storage rack, with attached rotatably to the end position of the fulcrum disposed in front of the product, from the back side to the end position of the product faces the commodity passage locking bar section Between the first ejector rotatable between the locking position where it abuts and locks it, and the release position where it retracts upward from the product passage and releases the last product, and between both side plate parts of the product storage rack. It is rotatably attached and inside the product passage A second ejector that is rotatable between a locking position that projects and locks the next-to-last item and a release position that retracts from the product path and releases the next-to-last item; An interlocking mechanism that interlocks the second ejector so that the other one is located at the release position when one of the second ejectors is located at the locking position; and a biasing means that biases the first ejector toward the locking position. at the time of sale, the first ejector,
Drive means for driving to the release position side against the urging force of the urging means.

According to this product dispensing device, when the product is on standby, the first ejector is located at the locking position by the urging of the urging means, the locking bar portion faces the product passage, and the last product is the product. By contacting (sale product) and locking this,
Hold a large number of products, including products for sale, in the product passage. The second ejector is located at the release position and retracts from the product passage by the action of the interlocking mechanism. In this case, the leg of the first ejector is rotatably supported at the fulcrum at a position on the front side of the sale product , and the locking bar portion abuts the sale product from the rear side. That is, since the sold product contacts the locking bar portion in such a positional relationship that it is sandwiched between the rotation fulcrum and the locking bar portion, the first ejector is
It is difficult for the product to rotate even if it receives the weight of the product, and thus the product can be stably held.

When the product is sold, the driving means is actuated to rotate the second ejector to the locking position, so that the second ejector projects into the product passage and locks the product next to the product to be sold (next-sales product). And the first ejector is the urging force
By pivoting upward to the release position against the urging force of the step , the product passage is retracted, the sale product is released, and the product passage is dispensed.

In this case, the product storage rack is opened at the upper edges of both side plate portions, and when the first ejector is rotated to the locking position side, the locking bar is brought into contact with the lower edges, It is preferable to have a notch for positioning the first ejector in the locking position.

According to this structure, when the first ejector is located at the locking position, the locking bar can be made to face the product passage, and the locking bar can be located at the lower edge of the notch of the product storage rack. The first ejector can be prevented from pivoting further downward from the locking position because it comes into contact with the product storage rack and is supported by the product storage rack. Therefore, it is possible to reliably prevent the first ejector from collapsing. it can.

[0012] In this case, when the first ejector is in the locking position, the locking bar portion abuts the final product below the extension of the line connecting the fulcrum and the center of the final product. It is preferable that it is configured as follows.

In this structure, the locking bar portion comes into contact with the final product below the extension of the line connecting the fulcrum and the center of the final product, so that the locking bar of the final product is contacted. The pressing force applied to the portion can act as a pressing force instead of a pressing force. As described above, this pressing force is supported by the product storage rack by the locking bar portion contacting the lower edge of the notch. Therefore, the first ejector is
It does not rotate in either the downward direction or the upward direction and is stably held in the locking position, and as a result, the product can be held more stably.

In these cases, it is preferable that a spacer having a predetermined thickness is detachably attached to the front surface of the locking bar portion of the first ejector.

If the diameter of the product to be stored in the product passage becomes smaller, the next-sale product will be stored at the rear position, so that at the time of sale, the next-sale product will overcome the second ejector and become a sale product. It is easy for two so-called products to be dispensed together, which is mistakenly paid out. According to this configuration,
When storing a product with a small diameter, simply attach a spacer to the front surface of the locking bar of the first ejector, and the product on the front side can be properly locked by the second ejector by the thickness of the spacer. Since it can be shifted to the position, it is possible to easily and surely prevent two products from being taken out.

In these cases, one of the pair of leg portions of the first ejector has a driven elongated hole arranged above the fulcrum, and is arranged rearward of the driven elongated hole and vertically with respect to the fulcrum. An arcuate guide hole extending is formed, and the driving means has a movable member that moves forward at the time of sale, and the movable member engages with the driven elongated hole of the leg portion to drive the first ejector. It is preferable to have a drive pin and a guide pin that engages with the guide hole and guides the rotation of the first ejector.

With this structure, when the product is sold, the movable member of the drive means moves forward, and the first ejector is driven by the drive pin of the movable member through the driven elongated hole, and moves upward with the fulcrum as the center. While being rotated to, the guide hole and the guide pin of the movable member allow the guide member to be smoothly guided to the release position. In this way, the driving means can be configured relatively simply by engaging the drive pin and the guide pin provided on the movable member with the driven elongated hole and the guide hole provided on the first ejector.

In this case, the guide hole of the first ejector is
It is preferable to have a lock hole portion that extends rearward from the upper end portion and that is engaged with the guide pin of the movable member when the first ejector moves to the locking position.

In this structure, when the first ejector is at the locking position, the guide pin of the movable member is engaged with the lock hole portion extending rearward from the upper end of the guide hole. For this reason, for example, when the product to be stored has a small diameter, the product to be sold slips under the first ejector,
Even if it acts so as to rotate it upward, the lower edge of the lock hole portion of the guide hole comes into contact with the guide pin of the movable member, whereby the upward rotation of the first ejector can be prevented. . As a result, even if the product has a small diameter, the product to be sold can be reliably locked, and the incorrect dispensing of the product can be reliably prevented.

In these cases, the interlocking mechanism has a drive slot formed in the one leg of the first ejector and a driven pin provided in the second ejector and engaged with the drive slot. Is preferred.

According to this structure, with the rotation of the first ejector, the second ejector is rotated by being driven through the driven pin that engages with the drive elongated hole of the first ejector. As described above, the first and second ejectors can be interlocked only by the engagement of the former driving elongated hole and the latter driven pin, and the driving elongated hole of the first ejector is Since it is provided on one leg together with the guide hole, the interlocking mechanism can be configured simply and compactly.

In this case, there is a plurality of holes with collars which can be fitted into the driven slot, the guide hole and the drive slot of one leg of the first ejector, and these collars are used as the driven slot. It is preferable to further include an adapter that is detachably attached to one leg of the first ejector in a state of being fitted in the guide hole and the drive elongated hole.

According to this structure, the drive pin and the guide pin of the movable member and the driven pin of the second ejector are inserted into the driven elongated hole, the guide hole and the driving elongated hole of the first ejector through the collar of the adapter. , Respectively. Therefore, each hole of the first ejector will not be worn by sliding of the drive pin or the like. Also, if the collar of the adapter becomes worn, only the adapter needs to be replaced with a new one, in which case the replacement can be easily performed by fitting.

In this case, the adapter is preferably made of wear-resistant plastic.

With this structure, the adapter with a collar can be easily and inexpensively manufactured by integrally molding plastic, and since the plastic has abrasion resistance, the life of the adapter can be extended.

In these cases, the drive means and the urging means are assembled as a drive unit by fitting them into each other, and the first and second ejectors and the assembled drive unit are mountable by being fitted into a product storage rack. Preferably.

According to this structure, the drive means and the urging means are assembled as a drive unit by fitting, and the drive unit including the first and second ejectors and the drive means and the urging means is fitted into the product storage rack. Since it is attached to the product, the product dispensing device can be assembled easily and efficiently without using screws or tools, and the manufacturing cost can be reduced.

The ejector main body 14a is retracted from the product passage 11 by being held in a released position which is rotated counterclockwise about 4b.

From this state, when the product S is loaded into the product passage 11 from the loading slot 9a, the product S rolls in the product passage 11 and moves backward, and the product S initially loaded.
The back surface of the first ejector 13 is brought into contact with and locked by the locking bar portion 13a of the first ejector 13 to become the sale product S1 and the second product S.
Stops in contact with the sale product S1, becomes the next sale product S2, and the subsequent products S are sequentially held in a state of being arranged in one line.

On the other hand, when the product S is sold, the solenoid 3
4 is activated, and as shown in FIG. 3 (b), the plunger 40
Is driven forward, and the slider 35 slides forward against the spring force of the coil spring 36. With this, the first
The ejector 13 has a lock hole portion 20 of the guide hole 20.
After a is disengaged from the guide pin 47, it rotates upward, and in conjunction with this, the second ejector 14 also rotates upward.
As the slider 35 slides, the first ejector 13 reaches the release position and the locking bar 13a releases the product passage 11 to lock the product S1 for sale, as shown in FIG. It is disengaged from the bar portion 13a and is discharged to the rear. Also, at this point, the second ejector 14 has reached the locking position, and the ejector body 14a is in the product passage 1
1 is projected and abuts on the next sale product S2 to lock it.

After the product S is dispensed, the solenoid 34
3 is stopped, the first ejector 13 is returned to the locking position shown in FIG. 3 (a), the second ejector 14 is returned to the release position, and the next-sale product S2 has the second ejector 14 It is disengaged from the second ejector 14 and locked by the first ejector 13 to become the next sale product S1.

As described above, according to the merchandise dispensing device 12 of the present embodiment, the merchandise for sale S1 is located between the rotation pin 49 of the first ejector 13 and the locking bar portion 13a. Since it comes into contact with the locking bar portion 13a,
The ejector 13 is hard to rotate even if the weight of the product S is received.
Ku, and therefore, it is possible to stably hold the commodity S. Further, as described above, the locking bar portion 13a is located at a position slightly below the extension line of the line connecting the fulcrum 18 and the center of the sale product S1 (point A in FIG. 3A), and the sale product S1. Therefore, even if the product for sale S1 tries to rotate the first ejector 13 by pressing the locking bar portion 13, the pressing force of the product for sale S1 acts as a pressing force instead of a lifting force. You can And this pushing down force,
Since it is supported by the rack body 8 with which the locking bar portion 13a abuts, the first ejector 13 can be stably held in the locking position without rotating the first ejector 13 in either the downward direction or the upward direction, and the product is more It can be held stably.

Further, when the first ejector 13 is in the locking position, the lock hole portion 20a of the guide hole 20 is engaged with the guide pin 47 of the slider 35, so that the pressing force of the product for sale S1 should be prevented. Even when it acts to push up the first ejector 13, the lower edge of the lock hole portion 20a contacts the guide pin 47, so that the upward rotation of the first ejector 13 can be reliably prevented.

The locking of the first ejector 13 by the lock hole 20a is particularly effective when the product S having a small diameter is stored. That is, although not shown, when the product S has a small diameter, the product S tends to slip into the lower side of the locking bar portion 13a to push up the first ejector 13, but even in such a case, By the lock by the lock hole 20a, the first ejector 13 can be prevented from rotating upward, and the sale product S1 can be reliably locked. Therefore, regardless of the size of the product S, erroneous payout of the product S can be reliably prevented.

Further, as described above, the rotary pin 49, the drive pin 46 and the guide pin 47 of the slider 35, and the driven pin 28 of the second ejector 14 are the rotary hole 17 of the first ejector 13 and the driven length. Hole 19, guide hole 20
The drive slot 21 and the drive slot 21 are engaged with each other via the collar 23a of the adapter 22. Therefore, these holes 17, 19, 20, 21 of the first ejector 13 are not worn by sliding of the rotating pin 49 or the like. Further, since the adapter 22 can be manufactured easily and inexpensively by integrally molding plastic, and is made of wear-resistant plastic, it is hard to wear,
Its life can be extended. In addition, the adapter 22
When the collar 23a is worn, only the adapter 22 needs to be replaced with a new one, and in that case, the replacement can be easily performed by fitting.

Shows a modified example of. The first ejector 13 is configured such that the spacer 53 is detachably attached to the front surface of the locking bar portion 13a. This spacer 53
Is made of a relatively soft plastic or the like having a predetermined thickness, and the pair of left and right claws 54, 54 are engaged with the engagement holes 55, 55 formed corresponding to the locking bar portion 13a. Is attached to the first ejector 13.

The spacer 53 is provided to prevent the so-called two products S from being mistakenly paid out together with the product S1 to be sold next time when the product S having a small diameter is stored. That is, although not shown, when the diameter of the product S becomes smaller, the next-sale product S2 comes to be stored in a position on the rear side of the product passage 11. Since it is easy to get over the protruding second ejector 14, two products S are likely to be dispensed. According to this modification, when the small-diameter product S is stored, the spacer 53 is simply attached to the first ejector 13 as described above, and the second-sales product S2 is sold to the second ejector 14 by the thickness of the spacer 53. Since it can be shifted to a position on the front side that can be properly locked with, it is possible to easily and reliably prevent two products S from being dispensed when they have a small diameter.

The present invention is not limited to the embodiment described above and can be implemented in various modes.
For example, although the embodiment is an example in which large and small canned beverages are stored in the product storage rack, the same effect can be obtained even when large and small bottled beverages are stored. Also, the first
With regard to the configuration of the second ejector, the drive mechanism, and the like, and the configuration in which these are connected to each other, those other than those shown in the embodiment can be appropriately adopted within the scope of the present invention. is there.
