Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a product dispensing device for a spiral type vending machine arranged vertically.

(B) Conventional technology Conventionally, this type of product delivery device consists of a drive shaft with a spiral member wrapped inside a product storage column, which has an opening for loading products on the front and an outlet for delivering products on the bottom. It is generally known that the product is placed in the vertical direction, the product is inserted and supported from the front opening into the gap between the spiral members, and the product is moved downward by a predetermined rotation of the drive shaft and delivered from the lower end of the spiral member through the delivery port. For example,
It is shown in Publication No. 7079.

(c) Problems to be Solved by the Invention The spiral-type product delivery device having the above configuration has a structure in which the product is inserted and supported in the gap formed between the helical sides of the helical spiral member. is housed and supported in the gap between the spiral members in an inclined state so that one end is downwardly directed toward the outlet. Further, since the spiral member is formed of a wire-wrapped member and the gap interval is wider than the thickness of the product, the product can move very freely within the gap. That is,
Due to the uniqueness of the spiral member being formed in a helical shape, the gap is narrower on the drive shaft side and widens outward from the drive shaft side. Therefore, since the distance between the helical sides must be made sufficiently larger than the thickness of the product, the stored product has a large degree of freedom within the gap, and this degree of freedom tends to increase as the product to be stored becomes larger. .

If this degree of freedom is large, there is a drawback that the product stored and supported in the lowest gap is easily pulled out of the delivery port, and may fall due to vibration or the like and be delivered illegally. Therefore, it is not possible to store and sell large products using a spiral type product delivery device, and the sale of large products requires the use of a complicated and expensive chain elevator type product delivery device.

In view of the above, the present invention provides an apparatus that can reliably prevent tampering even with large products and can reliably deliver the products.

(b) Means for solving the problem: A support member fixed to the drive shaft at a lower position of the spiral member and projecting in a substantially fan shape, and a rotatable end located above the support member close to the drive shaft side and a closing plate which is supported substantially horizontally by the supporting member in contact with the lower surface to close the outlet, and which can rotate downward to open the outlet when the supporting member is separated from the lower surface. The terminal end position of the spiral member and the protruding position of the support member are arranged in vertically corresponding positions, and the support member is placed in contact with the lower surface of the closing plate during product delivery standby.

(E) Function The present invention provides a support member on the drive shaft at a lower position of the spiral member, and a closing plate that can open and close the outlet by rotation of the support member, thereby controlling the end position and support of the spiral member. The position of the member is arranged vertically to correspond to the position of the spiral member, and the product stored and supported in the gap between the spiral members is supported on a closing plate that closes the delivery port during product delivery standby, and then delivered. .

(f) Embodiment The drawing shows a product delivery device according to an embodiment of the present invention. (1) is a roughly box-shaped product storage column provided inside the vending machine main body, with an opening in the front for loading products. (2), and a delivery port (3) for dropping and delivering the product is provided on the bottom surface. This product storage column (1
) has an upper end connected to a drive motor (4) and a lower end supported by a bearing member (5) installed between the front and rear walls (1 person) (IB) of the product storage column (1). 6) are arranged in the vertical direction. A spiral member (8) formed in a helical shape is wound around this drive shaft (6) via a mounting member (7), and the spiral member (8) is formed under pressure on both sides of the drive shaft (6). A product hole inserted through the front opening (2) is accommodated and supported in the gap (9). QOI is a support member fixed to the drive shaft (6) at a position below the spiral member (8).
6) It has a fan-shaped shape that projects approximately 120 degrees from the side, and the center portion (IOA) of the support member (10) is located below the terminal end (8A) of the spiral member (8). That's what I do. aυ is an axis C whose one end close to the drive shaft (6) is installed between the front and rear walls (IA) (IB).
It is a blocking plate that is rotatably supported on I2+ and can open and close the outlet (3), and is rotated upwardly by the elasticity of spring α9 and is abutted and locked by the stopper (I4) to close the outlet. (3) is held substantially horizontally so as to close it.

This closing plate αD is rotated downward by the load of the product hole to open the outlet (3), but the support member a value is lower than the outlet (3).
3) Lower surface (11A) of the closing plate (11) extending inward
By being located corresponding to the support member a, the blocking plate αB
0 prevents downward rotation and is supported in a substantially horizontal state. In addition, the vertical distance (2) between the closing plate αυ in a substantially horizontal state and the terminal end (8A) of the spiral member (8) is determined by the product (
The spiral member (
8) to the blocking plate αυ is reduced.

(Is indicates that the product hole supported on the blocking plate αυ is
I+) is regulated so as not to lean toward the side of the shaft a3, which is supported by the shaft.
It is a regulating member that prevents products from clogging, and the front and rear walls (IA)
(IB) (16) is the drive shaft (6
As shown in FIGS. 1 to 3, the control cam is provided to rotate with the rotation of the drive shaft ( ).
6) and the lower surface of the closing plate (11) (
The control switch aη is operated at a position corresponding to IIA) to stop the drive motor (4).

Next, the operation of the above configuration will be explained. Figures 1 to 3
The figure shows the product delivery standby state, and the product (5) is stored in each gap (9) of the spiral member (8) and on the closing plate αυ. Here, the product sending command is sent to the drive motor (4)
3, the drive motor (4) rotates the drive shaft (6) in the direction of the arrow shown in FIG. Therefore, each gap (9
) are gradually transported downward. On the other hand, the support member (10) starts to separate from the lower surface (11A) of the closure plate aυ due to the rotation of the drive shaft (6).

Then, as shown in FIG. 4, the support member 00)
1) When separated from the lower surface (11A), the blocking plate (like a closing plate) is released from the support by the support member (lω) and is rotated downward by the load of the product to open the outlet (3) and release the product (5). Then, this product sending command blocking plate (11)
is immediately rotated upward by the elasticity of the spring (13) and returns to the horizontal state by contacting the stopper (I4) 1. During this time, the support member OI holds the drive shaft (6) between the drive shafts (6) and the outlet (3).
It is located on the opposite side. When the drive shaft (6) further rotates, the rotating tip of the support member αω advances to correspond to the lower surface (IIA) of the closing plate αυ which has returned to the horizontal state, and the closing plate aυ is in a state capable of being supported. Due to the rotation of the drive shaft (6) after this supportable state, the product prisoner stored in the lowest gap (9) of the spiral member (8) is moved to the terminal end (8A) of the spiral member (8). away from the occlusion plate (11
) will be dropped on top. Therefore, the closing plate 0υ rotates slightly downward, but the lower surface (IIA) is supported by the supporting member α and the closing plate 0υ is maintained in a horizontal state. When the terminal end (8 members) of the spiral member (8) leaves the blockage plate αD and reaches the state shown in FIG. 3, the control cam (161) operates the control switch (17) to turn on the drive motor (4). Stop and return to standby state.

(G) Effects of the Invention As described above, the present invention provides a support member on the drive shaft at a lower position of the spiral member, and a closing plate that can open and close the outlet by rotation of the support member, and the spiral member The end position of the spiral member and the position of the support member are aligned vertically, and the product stored and supported in the gap between the spiral members is supported on a closing plate that closes the delivery port during product delivery standby, and then delivered. Because of this structure, even in the case of large products where the degree of freedom of the product within the gap between the spiral members is large, mischief such as unauthorized removal of the product can be reliably prevented and the product can be sent out reliably. It is something that can be done.
