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 No. 57-286 and Japanese Utility Model Application No. 56-159884).

In such a spiral type product discharging device, a spiral is fixed around a shaft extending in the vertical direction, and by rotating the shaft to which the spiral is fixed, the spiral is moved along both sides of the shaft. 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 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.

SUMMARY OF THE INVENTION 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's about doing.

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 shaft driven by a motor and extending vertically is pivotally provided approximately in the center of a product storage section with an open front and bottom surface, and a starting end has a small diameter and a terminal end has a large diameter. A spiral-shaped delivery member with a diameter of approximately one turn is provided with the starting end positioned at the top,
Products are stored in a stacked state on both sides of the shaft in the product storage section on the carry-out member, and when the products are carried out, the shaft is rotated by the motor, so that the products are stacked on both sides of the shaft on the carry-out member. 2
A product dispensing device for a vending machine configured to drop and carry out a product at the bottom of one of the products in a row, the shaft having a shaft extending from a position slightly near the end of the starting end of the discharging member. A protrusion extending upward is provided, and the protrusion is used to sandwich the product placed on the lowermost product between it and the inner wall surface of the product storage section when the product at the bottom is carried out. A product dispensing device for a vending machine is obtained.

[Effect]

In the product delivery device for a vending machine of the present invention, when storing products in the product storage section, the products are piled up on the delivery member on both sides of the shaft from the open part at the front of the product storage section. 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 shaft rotates during product transport, the transport member also rotates accordingly. As the carry-out member rotates, the starting end, that is, the upper end of the carry-out member pushes the lowest product outward in the radial direction of the shaft 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, a protrusion provided on the shaft that extends upward from a position slightly closer to the end of the starting end of the carrying out member pushes the next product placed on top of the carried out product slightly outward. The product is sandwiched between the protrusion and the inner wall surface of the product storage section. As a result, the next product is not carried out together with the previously carried out product, and each product 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 a schematic configuration of a product delivery device for a vending machine according to the present invention, in which 11 is a 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. The top plate 14, 15, and 16 fixed to the top surface of 12 are the left side plate, right side plate, and back plate of the product storage section 12, respectively. Reference numeral 17 denotes a shaft extending vertically at the center of the product storage section 12. A carry-out member 18 for controlling the carry-out of the product 10 is fitted into the middle and lower part of the shaft 17, respectively, and is fixed by a pin 19. The shaft 17 is rotatably supported by a pivot member 20 in which a pivot member 17a formed at the lower end is fixed to the back plate 16. Further, the upper end of the shaft 17 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 shaft 17 is configured to be rotatable.

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 shaft 17, and has an approximately straight line with a small diameter at the top and a large diameter at the bottom. A spiral-shaped unloading part 18-2 is integrally formed, and a locking part 18a is formed at the small diameter starting end of the unloading part 18-2, and a locking part 18a is formed on the outer circumferential surface of the cylinder 18-1 in the vertical direction. Two rows of extended protrusions 18b are formed. The two rows of protrusions 18b are connected to the unloading section 18-
2 (see FIGS. 3 and 5). Unloading section 18-2
The distance from the central axis of the shaft 17 is gradually increased from the starting end to the ending end, and the vertical distance between the starting end and the ending end is the distance between 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.

Slanted portions 18c are provided at the upper ends of the cylindrical body 18-1 and the two rows of protrusions 18b to prevent the product 10 from getting caught.

The connecting member 22 connects the motor 24 with a speed reduction mechanism and the shaft 17, so that the motor 24 rotationally drives the shaft 17, and the cam portion 22a is connected to the shaft 17.
Concave portion 22b and cam portion 22a formed at 180° position
The shaft 17 is
is driven intermittently in 180° increments.

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 the right side 15 by locking pieces 26a, 26b. Above spacer 26,2
Reference numeral 6 forms an upwardly inclined guide portion 26c and a vertical guide portion 26d, the lower ends of which are located directly above the locking portion 18a beyond the upper surface of the product 10 on the unloading portion 18-2 of the unloading member 18. extending downward to
Further, the upper end of the vertical guide part 26d is located at the bottom when the product to be carried out is on the locking part 18a.
The product 10 to be transported is placed at a lower position that does not exceed the upper surface of the product 10 directly above it, and the product 10 to be transported is placed at the lowest position.
The product 10 directly above the product 10 to be carried out is brought closer to the shaft 17 to ensure that the product 10 is locked by the locking portion 18a.

Next, the operation of transporting the product 10 will be explained. First, the product 10 to be filled is placed on the shaft 17 in 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 in response to a sales signal based on the insertion of a predetermined coin in a state where the products 10 are filled, the shaft 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 to the left in the direction of the arrow shown in FIG. 4 so that the product 10 can easily fall. That is, due to the vertical position difference between the locking part 18a of the carrying-out member 18 and 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 moved to the left by the locking part 18a. Push it. As the rotation progresses further, as shown in FIG. 6, one product 10 at the bottom of the row of products on the left side 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 stopped from moving downward by the locking part 18a, and similarly, in the product row on the right side, the product 10 directly above the lowest position product 10 is stopped by the locking part 18a. Continuing from 18a, the downward movement is stopped 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 the next predetermined coin, the product 10 is moved to the bottom position of the product row on the right side, similar to the unloading operation of the product 10 shown in FIGS. 2 to 6. One product 10 on the carry-out section 18-2 is carried out.

The carrying out member 18 provided at the bottom of the shaft 17 in this way
The products 10 are carried out alternately from the left and right product rows, and the delivery member 18 provided in the middle of the shaft 17 is connected to the delivery 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.

In addition, in this embodiment, as described above, the cylinder 18
-1, two rows of protrusions 18b extend upward from a position slightly closer to the terminal end of the starting end of the carrying-out section 18-2.
(See Figures 3 and 5). Thereby, the paper container (commodity) 10 locked on the locking portion 18a is held by narrowing the space between the protrusion 18b and the side spacer 26. That is, when carrying out the product, the next product placed directly above the lowest product to be carried out is pushed slightly outward by the protrusion 18b and is lightly sandwiched between it and the side spacer 26. This prevents the next product from coming off due to inclination in the gap between the cylinder 18-1 and the vertical guide portion 26d, as shown as 10' in FIG. There's something I made. In addition, the above protrusion 1
8b, due to the inclination of the product 10' shown in FIG.
8 prevents the product 10' from being bitten.

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.

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. In this case, the unloading member 18 may have a structure that does not require the cylindrical body 18-1. In this case, the protrusion 18b may be provided directly on the shaft 17.

〔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 carrying-out member is detachably attached to the shaft, a carrying-out member suitable for the size of the product can be selectively attached, and a large number of products can be handled.

In addition, the shaft is provided with a protrusion that extends upward from the starting end of the unloading member, which is slightly closer to the end of the unloading member, so that when unloading the items, instead of multiple items being unloaded, the items can be unloaded one by one. It is possible to obtain a product delivery device for a vending machine with high delivery reliability.
