Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a product delivery device for a vending machine,
In particular, the present invention relates to a product delivery device suitable for handling rectangular and cubic products such as beverages in paper cartons.

[Conventional technology]

In this type of vending machine, a conventionally known product discharging device, for example, a spiral type is used (see, for example, Japanese Utility Model Application Publication No. 56-159884 and Japanese Utility Model Application Publication No. 57-286).

In such a spiral type product discharging device, a spiral is fixed around a rod extending in the vertical direction, and by rotating the rod to which the spiral is fixed, the spiral is moved along both sides of the rod. Products inserted into the gaps were being transported out one by one from below. Therefore, in the spiral method, since the spirals are located between vertically adjacent products, the product storage capacity is reduced and one product is placed between vertically adjacent spirals.
It is necessary to insert each product one by one, making the filling work of products complicated.

FIG. 1 shows a schematic configuration of the conventional spiral type product delivery device in a front view. In FIG. 1, reference numeral 1 denotes a box-shaped product storage section with an open front and bottom surface. The product storage section 1 consists of a top plate 1a, left and right side plates 1b and 1c whose lower portions are expanded and bulged outward in the left-right direction, and a back plate 1d. A carry-out body 5 with a spiral 3 fixed around a shaft 2 by a fixing rod 4 is arranged in the center of the product storage section 1, and a pivot support member 6 has a lower end of the shaft 2 of the carry-out body 5 fixed to a back plate 1d.
The upper end of the shaft 2 is fixed to a connecting member 8 fitted in a bearing 7 provided on the top plate 1a to constitute a product delivery device.

In the conventional spiral type product discharging device described above, the product 10 is inserted into the gap of the spiral 3 from the lower end of the spiral 3 by intermittently driving the shaft 2 by 180 degrees by a motor 9 with a speed reduction mechanism connected to the connecting member 8. are carried downward one by one.

[Problem that the invention seeks to solve]

As shown in Fig. 1, in the above product delivery device,
It will become clear that the disadvantage is that gaps are created between the products 10 in the vertical direction, reducing the amount of products 10 stored, and that a plurality of products 10 cannot be filled at once.

An object of the present invention is to provide a product delivery device for a vending machine that eliminates the drawbacks of the conventionally known product delivery devices, allows more products to be stored in a narrow space, and facilitates product filling operations. It is about providing.

Another object of the present invention is to provide a vending machine which is capable of achieving the above-mentioned objects and which has high delivery reliability, and which allows products to be taken out one by one without having to take out a plurality of products at the time of delivery. Our objective is to provide a product delivery device.

[Means for solving problems]

According to the present invention, a vertically extending rod driven by a motor is provided approximately in the center of a product storage section with an open front and bottom surface, and at least a lower portion of the rod has a starting end with a small diameter and a terminal end with a large diameter. A vending machine for carrying out products in a vending machine in which a spiral carrying-out member having one turn is provided with the starting end positioned at the top, and products are stored in a stacked state on the carrying-out member on both sides of the rod in the product storage section. In the device, the central axis of the rod is offset from the central axis of drive by the motor so as to be parallel to the central axis of drive,
When the inside of the product storage section is viewed transparently from above, the drive center axis is located in a direction directly opposite to a position slightly closer to the end of the starting end of the delivery member with respect to the center axis of the rod. A product dispensing device for a vending machine is obtained, which is characterized in that:

[Effect]

In the product delivery device for a vending machine according to the present invention, when storing products in the product storage section, the products are stacked from the open part at the front of the product storage section onto the delivery member on both sides of the bar. It will be stored. Therefore, more products can be stored in a narrow space, and a plurality of products can be filled at once when storing the products, making the product filling operation easier.

When the rod rotates when carrying out the product, the carrying-out member also rotates accordingly. In accordance with the rotation of the carry-out member, the starting end, that is, the upper end of the carry-out member pushes the lowest product outward in the radial direction of the rod and enters below the product above it. When the carry-out member rotates further, the product at the bottom is detached from the carry-out member and falls downward, and the product above it is placed on the carry-out member. At this time, by making the rod eccentric from the central axis of drive by the motor as described above, the side of the position slightly closer to the terminal end of the starting end of the carrying out member is narrowed, and the bar is placed on top of the carried out product. The next product that has been loaded is pushed slightly outward by the rod, and the next product is sandwiched between the rod and the inner wall surface of the product storage section. By this,
The next product is not carried out together with the carried out product, and the products can be carried out one by one.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 is a front view showing the general configuration of the product delivery device for a vending machine according to the present invention, in which 11 is the product delivery device, 12 is a box-shaped product storage section with an open front and bottom surface, and 13 is a product storage section. Top plates 14, 15, and 16 fixed to the upper surface of the section 12 are the left side plate, right side plate, and back plate of the product storage section 12, respectively. Reference numeral 17 denotes a rod that is slightly offset from the center of the product storage section 12 and extends in the vertical direction. Product 1 is placed in the middle and lower part of rod 17.
A carry-out member 18 for controlling the carry-out of 0 is fitted and fixed by a pin 19. Central rods 17-1 and 17-2 are attached to the side surfaces of the upper and lower ends of the rod 17, which determine the central drive axis (rotation center) of the motor 24. The center rod 17-2 has a pivot member 20 with a pivot member 17a fixed to the back plate 16.
It is rotatably supported by. Also center rod 1
7-1 is connected by a pin 23 to a connecting member 22 that is rotatably fitted into a bearing 21 formed on the top plate 13. In this way, the central axis of rod 17 is determined by central rods 17-1 and 17-2. It is shifted in a predetermined direction from the central axis of drive by the motor 24 so as to be parallel to the central axis of drive.

Referring to FIGS. 3 to 6, including FIG. 2, the carrying-out member 18 is attached to the outer periphery of a cylinder 18-1 that is fitted and attached to the rod 17. A spirally wound unloading portion 18-2 is integrally formed, and a locking portion 18a is further formed at the small diameter starting end of the unloading portion 18-2. Unloading section 18-2
The distance from the central axis of the rod 17 is gradually increased from the starting end to the ending end, and the vertical distance between the starting end and the end is the same as the product 1 to be stored and carried out.
The height dimension is set to be approximately the same as or not to exceed the height dimension of 0.

A sloped portion 18c is provided at the upper end of the cylindrical body 18-1,
This prevents the product 10 from getting caught.

In addition, in FIGS. 3 and 5, It shows. As is clear from these figures, the center axis of the rod 17 is shifted from the drive center axis X of the motor 24 so as to be parallel to the drive center axis When viewed transparently from above, the drive center axis X is located in a direction exactly opposite to the position of the starting end of the unloading section 18-2, which is slightly closer to the terminal end, with respect to the central axis of the rod 17.

Note that the connecting member 22 connects the motor 24 with a speed reduction mechanism and the center rod 17-1, and the motor 2
4 to rotate the rod 17, and a switch 25 disposed opposite to the periphery of the cam portion 22a.
The rod 17 is driven intermittently by 180 degrees.

Further, numerals 26 and 26 are spacers that are detachably provided on the left side plate 14 and the right side plate 15 in correspondence with the carrying-out member 18. These spacers 26, 26 are respectively locked into locking holes (not shown) formed in the left side plate 14 and right side plate 15 by locking pieces 26a, 26b. The above spacers 26, 26
The guide portion 26c is inclined upward and the guide portion 2 is vertical.
6d, and its vertical guide portion 26d
The lower end extends downward to almost immediately above the locking part 18a beyond the upper surface of the product 10 on the carrying out member 18,
Furthermore, when the product to be carried out at the lowest position is on the locking part 18, the upper end of the vertical guide part 26d is set at a lower position that does not exceed the upper surface of the product 10 directly above the product to be carried out at the lowest position. This allows the product 10 to move away from the rod 17, and brings the product 10 directly above the product 10 to be carried closer to the rod 17 to ensure that the product 10 is locked by the locking part 18a.

Next, the operation of transporting the product 10 will be explained. First, the product 10 to be filled is placed on the rod 17 inside the product storage section 12.
are stacked and stored on the locking portions 18a of the carry-out member 18 on the left and right sides and on the carry-out portion 18-2. At this time, at the front opening of the product storage section 12, a conventionally known product drop stopper (not shown) facing the product rows is of course used to prevent the two vertical rows of products 10 from falling.

When the motor 24 is energized by a sales signal based on the input of a predetermined hardening in a state where the products 10 are filled, the rod 17 is driven in the direction of the arrow as shown in FIGS. Rotate in the direction of the arrow to secure the product 10 on the unloading section 18-2 to the locking section 1.
8a in the direction of the arrow shown in FIGS. 4 and 5, so that the product 10 can easily fall. That is, the locking portion 18a of the carrying out member 18
Due to the difference in the vertical position of the carrying out part 18-2, the right side of the product 10 to be carried out on the carrying out part 18-2 is pushed to the left by the locking part 18a, but the central axis of the rod 17 is eccentric with respect to the drive center axis of the motor 24, so the locking portion 18a
It has the effect of pushing the side part of the product 10 and promoting the removal of the product 10. As the rotation progresses further, as shown in FIG. 6, one product 10 at the bottom of the product row is dropped and carried out. At this time, in the product row on the left side, the product 10 directly above the lowest product 10 that has been carried out is locked by the locking part 18a, and similarly, in the product row on the right side, the product 10 directly above the bottommost product 10 is locked by the locking part 18a. and is locked by the unloading section 18-2.

When the motor 24 rotates the carry-out member 18 through an angle of 180 degrees from the position shown in FIG. 2, the motor 24 is stopped at that position by being de-energized by the recess 22b of the cam portion 22a and the switch 25.

When the motor 24 is energized by the sales signal generated by inserting a predetermined coin, the unloading section is moved at the lowest position of the row of products on the right side, similar to the unloading operation of the product 10 shown in FIGS. 2 to 6. One product 10 above 18-2 is carried out.

The carrying out member 18 provided at the bottom of the rod 17 in this way
The products 10 are carried out alternately from the left and right product rows, and the carry-out member 18 provided between the rods 17 is connected to the carry-out section 1 at the longitudinally intermediate portion of the left and right product rows.
8-2 and the locking part 18a, the left and right products 1 are
0 is locked so that the product 10 at the bottom of the product row filled in the product storage section 12 does not bear the entire weight of the product row. As a result, the left and right product rows are locked by the intermediate delivery member 18, which prevents damage or deformation of the products 10 that are locked to the delivery member 18 at the lowest position. A reliable unloading operation can be performed.

Therefore, according to the present embodiment, it is possible to obtain a product dispensing device for a vending machine that is simple in structure and inexpensive, and also facilitates product filling work and increases the amount of products stored in the same space. It has the effect of ensuring that products can be transported out.

Further, in this embodiment, as described above, the rod 17
The central axis of is shifted from the central axis of the drive by the motor 24 so as to be parallel to the central axis of the drive, and when the interior of the product storage section is viewed transparently from above the product storage section, the drive The central axis is located in a direction exactly opposite to the central axis of the rod 17 from the position of the starting end of the unloading section 18-2, which is slightly closer to the terminal end. In this way, by making the rod 17 eccentric, the locking portion 18a side of the delivery member 18 is narrowed, and the product 10 locked on the locking portion 18a is securely held between it and the side spacer 26. This is how it was done. In other words, when the product is carried out, the next product 10 to be carried out that was placed directly above the lowest product to be carried out.
is pushed slightly outward by the cylindrical body 18-1 and lightly sandwiched between it and the side spacer 26, thereby allowing the product to be inserted into the gap between the cylindrical body 18-1 and the vertical guide portion 26d. This prevents it from falling out due to the slope. Furthermore, the tilt of the product prevents the product from being caught by the carry-out member 18 when the carry-out member 18 rotates.

Therefore, according to this embodiment, there is also an effect that the products are carried out one by one without having to carry out a plurality of products at the time of carrying out the products. Furthermore, as mentioned above, by making the rod 17 eccentric,
Since the carrying-out member 18 is wider on the carrying-out part 18-2 side, it is possible to prevent the product 10 from getting caught on the carrying-out part 18-2.

In the above embodiment, the unloading section 18-2 is made of a plate, but it goes without saying that it may be made of a rod.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to obtain a product discharging device for a vending machine that can store more products in a narrow space with an inexpensive and simple structure, and facilitates product filling work. .

Furthermore, if the carry-out member is detachably attached to the rod, the carry-out member suitable for the size of the product can be selectively attached, which has the effect of making it possible to handle a large number of products.

Furthermore, by making the rod eccentric, it is possible to obtain a product delivery device for a vending machine that has high delivery reliability and allows products to be delivered one by one without having to carry out multiple products during product delivery. be able to.
Furthermore, by making the rod eccentric, the carrying-out section side of the carrying-out member becomes wider, so that it is possible to prevent the product from getting caught on the carrying-out section.
