Description

TECHNICAL FIELD The present invention relates to a raw material storage device for a cup-type beverage vending machine having a main body in which a raw material container in which powdery granular raw material for beverage is charged and stored from an upper input port is provided. It is a thing.

2. Description of the Related Art In recent years, a cup-type beverage vending machine's raw material storage device has a rotary opening and closing type lid structure that does not require attachment and detachment of the lid that seals the inlet of the raw material container when replenishing beverage ingredients, and cleaning A simple structure with good workability is desired.

An example of the raw material storage device of the conventional cup-type beverage vending machine described above will be described below with reference to the drawings.

FIGS. 4 to 8 show the structure of a raw material storage device of a conventional cup-type beverage vending machine.

In the figure, 1 is a main body case of a beverage vending machine, 2
Is a base plate provided in the main body case 1, and 3 is a plurality of (five in this case) raw material containers placed on the base plate 2 and stored and installed side by side in the main body case 1. This raw material container 3
Each has a carry-out mechanism (not shown) at the bottom for carrying out a certain amount of raw material from the carry-out port 3a according to a sales signal.
The upper part is squeezed like a terrace and the opening 3b is opened on the upper surface. Reference numeral 4 denotes a lid provided at the inlet 3b. This lid 4
Is rotatably held by a bent portion 5a raised at both ends of a fixture 5 fixed to the back surface of the raw material container 3 via a rotary shaft 6. Reference numeral 7 denotes a spring. One end of the spring 7 is locked to a holding portion 5b raised to the lower end of the fixing member 5, and the other end is locked to one end of a rotation guide piece 8. The other end of 8 is locked to the lid 4 via a shaft 9.

The operation of the raw material storage device of the cup-type beverage vending machine configured as described above will be described below.

First, in a normal beverage sales state, the lid 4 is closed by the force of the spring 7 attached as shown in FIG. 6, and the inlet 3b of the raw material container 3 is sealed. Next, when the raw material container 3 is filled with the raw material, the lid 4 is lifted upward with the pivot shaft 6 as a fulcrum, and the spring 7 begins to gradually expand. The force acts in the opening direction. At this time, even if the rotational power applied to the lid 4 is removed, the lid 4 is kept open by the force of the spring 7. Further, at this time, the lid 4 is in contact with the top surface of the main body case 1, so that opening more than necessary is prevented. FIG. 8 shows this state.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described conventional configuration, since many components are used in the fourth rotation opening / closing mechanism, cleaning of stains caused by the beverage raw material of the rotation opening / closing mechanism and disassembly and assembly are performed. It had the drawback of requiring a great deal of time.

The present invention solves the above-mentioned conventional problems, and provides a raw material storage device for a cup-type beverage vending machine having a simple lid opening / closing mechanism that is easy to clean and disassemble and assemble.

Means for Solving the Problems To achieve this object, the raw material storage device of the cup-type beverage vending machine of the present invention has one end at the rear of the input guide port of the partition member located above the input port of each raw material container. An open bearing is provided, and the lid is rotatably supported by a fulcrum shaft having a flat portion with one end on the circumference being cut off,
Similar to the fulcrum shaft, a leaf spring material made of an elastic material having a flat portion with one end on the circumference being cut off is fitted between the bearing and the fulcrum shaft.

With the above-described structure, the present invention has the same effect as the conventional one with the simple structure of the leaf spring material fitted between the bearing provided on the partition member and the fulcrum shaft of the lid as the lid opening / closing mechanism. The lid can be easily attached / detached by matching the obtained opening with the flat portion of the fulcrum shaft at an angle that exceeds the upper limit of the normal opening angle with respect to the partition member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a raw material storage device of a cup-type beverage vending machine according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. Detailed description is omitted.

In FIG. 1, reference numeral 10 denotes a partition member extending above the input port 3b of the plurality of raw material containers 3 arranged side by side. This partition member
Reference numeral 10 denotes a loading guide port 10a provided at a position corresponding to the loading port 3b of each raw material container 3, a bearing 10b located at a rear portion of the loading guide port 10a, and an opening portion 10c in which one end of the bearing 10b is cut open. It is formed from and. Reference numeral 11 denotes a lid provided at the inlet 3b. The lid 11 is rotatably supported by the bearing 10b via a fulcrum shaft 11c having a circumferential portion 11a and a flat portion 11b with one end on the circumference missing. 12 is the bearing 1
It is a leaf spring material made of an elastic material fitted between 0b and the fulcrum shaft 11c. The leaf spring member 12 is to be fixed to the arc portion 12a, the flat portion 12b lacking one end of the arc portion 12a, and the bearing 10b of the partition member 10 in a state along the outer periphery of the fulcrum shaft 11c of the lid 11. The arcuate portion 12a is composed of locking portions 12c that are bent and formed in a substantially L shape at both ends.

The operation of the raw material storage device of the cup type beverage vending machine configured as described above will be described below. First, FIG. 1 shows a state in which the lid 11 is completely closed. The leaf spring material 12 fixed to the bearing 10b is the circumferential portion of the fulcrum shaft 11c.
Along with the outer peripheral shape including 11a and the flat portion 11b, they are in close contact with each other without receiving a force. Next, FIG. 3 shows a state in which the lid 11 is opened. The circumferential portion 11a of the fulcrum shaft 11c is a flat portion of the leaf spring material 12.
By forcibly deforming 12b along the circumferential shape, the leaf spring material 12 acts as a force for stopping the rotation of the fulcrum shaft 11c. At this time, the lid 11 is held open.

As described above, according to the present embodiment, as the rotation opening / closing mechanism of the lid 11, only the leaf spring material 12 fitted between the bearing 10b provided on the partition member 10 and the fulcrum shaft 11c of the lid 11 is simple. With such a structure, the same effect as the conventional one can be obtained. Further, the partition member 10, the lid 11 and the leaf spring material 12 are assembled and taken out to the outside of the main body case 1, and the lid 11 is normally opened with respect to the partition member 10 and again exceeds the upper limit, that is, at 90 ° in this case, bearing
The lid 11 and the leaf spring material 12 can be easily attached and detached without a tool by aligning the open portion 10c of the 10b with the flat portion 11b of the fulcrum shaft 11c.

As described above, the present invention has a bearing provided on a partition member, a lid rotatably supported on the bearing via a fulcrum shaft,
With a simple structure that utilizes the elastic force due to the deformation of the leaf spring material fitted between the bearing and the fulcrum shaft, it is possible to realize a lid opening / closing mechanism equivalent to the conventional one. Furthermore, since the lid can be easily detached from the partition member without using a tool when the upper limit of the normal opening of the lid is exceeded, the workability of assembling the rotation opening / closing mechanism can be improved.
