BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product dispensing device for a vending machine, which dispenses the lowermost products one by one from a state where box-shaped products are stacked in two rows in front and rear.

[0002]

2. Description of the Related Art In some vending machines, box-shaped products are stored in front and rear rows. In this product, when the products in the bottom row were to be thrown out one by one, the products in the back row were pushed out to push out the products in the front row, and the products moved to the front row were directly pushed out. FIG. 38 shows an example. A delivery means such as a chain or a belt provided with a delivery projection 90 on the surface of the endless material 9 is arranged at the bottom of a product storage section for loading and storing the products 8 in front and rear rows, and the endless material 9 is driven to rotate. When the feeding projection 90 pushes the lowermost product 8 ₂ in the rear row forward, the lowermost product 8 _{1 in the} front row is pushed out and ejected. Then, when the feed projection 90 further pushes the product 8 ₂ that has moved to the front row, this product 8 ₂
Is also thrown out.

[0003]

In this case, when the products in the front row are pushed out and the products in the front row are pushed out, the weight of the products in the upper row is sometimes applied. I deformed the products on the back row side,
Due to this deformation, the ejection of products becomes unstable.

The present invention has been made in view of the above points, and its purpose is to deform products stacked in two rows in the front and rear from the lower side in order. There is no product dispenser for vending machines.

[0005]

According to the present invention, among the products stacked in the front and rear two rows, the product located in the lowermost row in the front row is thrown out, and then the product located in the lowermost row in the rear row is thrown out. A product dispensing device for a vending machine that dispenses a product located at the bottom of the front row and a product located at the bottom of the rear row to the front row while the product at the bottom of the front row is being dispensed. A feed-in means, a push-up means that pushes up the products in the rear row and secures an operation space for the above-mentioned feed-out means on the rear side of the product in the lowermost row of the front row, and an interlocking means that interlocks these feed-out means, the feed-in means and the push-up means. It is characterized by consisting of.

[0006]

According to the present invention, the lowermost product in the front row is not pushed and ejected by the lowermost product in the rear row, but is directly pushed by the delivery means while the lowermost product in the rear row is being pushed up. Be thrown out. As the sending-out and sending-in means here, the one formed by the rotationally driven feeding pawl can be preferably used, and the pushing-up means is a pushing-up cam rotating at a lower speed than the feeding pawl, or the feeding means and the intermittent means. A push-up cam integrally formed with the feed claw that is rotationally driven at a lower speed than the driving or feeding means can be preferably used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. In FIG. 1, reference numeral 1 is a storage portion for storing box-shaped products 8 in front and rear rows. A delivery means for delivering the article 8 located at the bottom of the front row downward,
Disposing the feeding means for feeding the products 8 located at the bottom of the rear row to the front row side, and the pushing up means for pushing up the goods 8 in the rear row and securing the operation space of the feeding means at the rear side of the goods 8 at the bottom row of the front row. is there.

The delivery means here is formed by two feed claws 31 and 32 which are lined up and down below the product 8 in the front row, and the feed-in means is formed by feed claws 33 and 34 which are lined up and down below the product 8 in the back row. The feed claws 31 to 34 are all rotationally driven at the same speed. The push-up means is formed by two push-up cams 41 and 42 which are coaxially supported by the feed pawls 33 and 34 and are rotationally driven at half the speed of the feed pawls 31 to 34. It should be noted that the feed pawls 31 to 34 and the push-up cams 41 and 42, which are located in front of and behind the feed pawls 31 to 34, have rotational loci overlapping with each other, but as shown in FIG. 13, they are arranged so as to be displaced in the rotational axis direction. They do not interfere with each other. Further, the feed claws 31 to 34 and the push-up cams 41 and 42 are connected to a single motor train wheel (not shown).
The rotation speed difference between the feed claws 31 to 34 and the push-up cams 41 and 42 is set. The train wheel constitutes the interlocking means.

Next, the operation will be described. FIG. 1 shows the first standby state, in which the products 8 ₁ , 8 ₃ , 8 _{5 in the} front row are ...
Are pushed up by the feed claws 31, and the articles 8 ₂ , 8 ₄ , 8 ₆ ... In the rear row are pushed up by the push-up cams 41, 42. When the motor rotates in this state in response to the product ejection instruction, the feed claws 31 to 34 start to rotate and the lifting cams 1 and 42 start to rotate at a half speed. As shown in Fig. 7, the products 8 ₁ , 8 ₃ , 8 ₅ in the front row descend, but the products 8 ₂ , 8 ₄ , 8 _{6 in the} rear row move up the cams 4.
1, 42 and the feed pawls 33, 34 are still pushed up, so that the operation space of the feed pawl 32 is secured on the rear side of the article 8 _{1 at} the bottom of the front row. And
As shown in FIGS. 2 and 3, the products in the back row 8 ₂ , 8 ₄ , 8
_{When 6} ... is pushed up by the back of the push-up cams 41, 42 and the feed claws 33, 34, the feed claw 32 pushes out the product 8 _{1 in} the lowermost row in the front row, and the feed claw 32 becomes a product 8 _{2 in} the rear row. If you exit from the lower position, as shown in Fig. 4,
As the products 8 _2, 8 ₄ , 8 _{6 in the} rear row descend, and the feed claws 31 start to push out the product 8 _{1 in} the lowermost row in the front row instead of the feed claws 32, as shown in FIG. 34 starts pushing out the product 8 _{2 at} the lowermost stage of the rear row, and as shown in FIG. 6, the product 8 ₂ is started by the feed claw 33 in place of the feed claw 34, and the product 8 ₁ is moved as shown in FIG. When the ejection is completed, the motor stops and enters the second standby state. At this time, the product 8 ₂ at the bottom of the rear row is in a state of sneaking under the products 8 ₃ , 8 ₅ ... In the front row.

As is clear from FIG. 4, the feed claw 3

Front row product 8₁Is pushed up and the second standby state
In the state, the product 8 to be ejected next by the feed claw 31₂Located in front of
And vending machines are tilted because they are
Even if it happens, the product 8 to be released next will fall out.
I don't care.

When the motor rotates in response to the next product ejection instruction, as shown in FIGS. 8 to 12, the feed claw 33 and the feed claw 32 are provided.
And the product 8 ₂ are sequentially delivered by the feed claws 31. During this period, since the products 8 ₄ , 8 _{6 in the} rear row are continuously pushed up by the push-up cams 41, 42, the operation space of the feed claw 32 is reduced. It is secured below the product 8 ₄ , and the feed claws 33 and 34 do not push the product 8 _4, and the state shown in FIG. 1 is restored when the dispensing of the product 8 ₂ is completed. Commodity 8 ₃ is to be subsequently ejected, and then commodities 8 ₄ , 8 ₅ , 8 ₆ ... Are ejected in this order.

14 to 25 show another embodiment. Here, as the pushing-up means, the feeding claw 3 which is a feeding means.
The push-up cams 41 and 42 formed integrally with the feeding claws 3 and 34 are used, and the rotation speed of the feeding claws 33 and 34 is set to half that of the feeding claws 31 and 32, and the feeding claws 33 and 34 feed during one rotation. A wheel train connecting the motor and these is set so that the claws 31 and 32 rotate twice. In the case of this embodiment, the operation is the same as that of the above-mentioned embodiment.
From the first standby state shown in FIG. 4 to the second standby state shown in FIG. 20 by throwing out the product 8 ₁ at the bottom of the front row and sending the product 8 _{2 at} the bottom of the rear row to the front side in the order shown in the figure. Figure 2
After the product 8 ₂ shown in FIG. 5 is thrown out, the state returns to the state shown in FIG.

Also in this case, the product does not fall out in the standby state, and when the rear row product 8 ₂ is slipped under the front row product 8 ₃ , as shown in FIG. Since the product 8 ₃ is floated by the above, the rear-row product 8 ₂ can be fed smoothly. Further, because the push-up cams 41 and 42 as push-up means are integrally formed on the feed claws 33 and 34 and the rotation speed thereof is half that of the feed claws 31 and 32, the product 8 and the feed claw 33 interfere with each other. Will occur, but
In order to prevent this, the feed claw 33 is provided with a notch 36 to prevent occurrence of interference as shown in FIG. The notch 37 provided on the feed claw 32 is also for preventing interference with the product, as shown in FIG.

26 to 37 show another embodiment. This is the same as the above-described embodiment in that the push-up cams 41 and 42 that are push-up means are integrally formed with the feed claws 33 and 34 that are feed-in means, respectively. The rotation speed of the feed claw 32 is the same as that of the feed claw 32.
The feed claws 33 and 34 are made to perform intermittent rotation in which rotation is stopped midway so that 34 rotates once. This intermittent rotation is caused by gears 55 and 56 that mesh with gears 53 and 54 provided integrally with the feed claws 33 and 34 to transmit the rotation of the motor to the feed claws 33 and 34, respectively. This is achieved by providing the toothless portions 57 and 58 that do not engage each other over a half circumference.

When the feed claws 31 and 32 start rotating from the first standby state shown in FIG. 26, the push-out of the lowermost product 8 _{1 in} the front row is performed as shown in FIGS. 27 and 28. when done in 32, feed pawl 33 which also serves as a push-up cam 41 is stopped in a state of pushing up the back row of the product _82, as shown in FIG. 29, sent on behalf of the feed pawl 32 pawl 31 There lowers the rear row of items 8 ₂ claws 33 and 34 feed the time to start the extrusion of the product ₈₁ is started to rotate, as shown in FIGS. 30 and 31, the delivery of items 8 ₁ by the feed pawl 31, feed Product 8 with nails 34, 33
₂ is carried out in parallel, and as shown in FIG.
The second standby state is entered at the time when the ejection of the product 8 ₁ is completed.

33 and FIG.
As shown in 34, the rear row by the lifting cams 41 and 42

Return to the state.

The front side of the surface on which the product 8 to be sent slides on the upper surface is made slightly higher than the rear side because the product 8 ₂ in the rear row is pushed and sent below the product 8 _{3 in} the front row. This is to prevent the front end of the product 8 _{2 from} being caught by the rear end of the second-stage product 8 ₃ in the front row. Also in this embodiment, the feed claws 31 prevent the product 8 located at the lowermost stage in the front row from falling out during both of the standby states.

The standby state shown in each of the above-mentioned embodiments is merely an example, and any time may be set as the standby state as long as it is a time until the product is completely dispensed.

[0019]

As described above, in the present invention, the lowermost product in the front row is not pushed out by pushing the lowermost product in the rear row, and the product in the lowermost row in the rear row is pushed up directly by the delivery means. Since the product is pushed and ejected, the product is less likely to be deformed, and accordingly, the ejection is not unstable. Further, since the operation space of the delivery means is secured by the pushing-up means, it is not necessary to leave a space between the products in the front row and the products in the rear row, which is also advantageous in reducing the thickness of the vending machine. It is a thing.

When a feed claw that is rotationally driven is used as the feeding and feeding means, and a push-up cam that rotates at a slower speed than the feed claw is used as the pushing-up means, each of these means is simple and compact. It is possible to further reduce the number of parts when the push-up cam is integrally formed with the feed pawl which is the feed means so as to be driven at low speed or intermittently.
