Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a powder raw material discharging device for a vending machine such as a coffee vending machine.

[Prior art]

In general, this type of raw material delivery device is configured to transport the powdered raw material stored in a powdered raw material storage tank 1 through a raw material discharge port 4 by rotation of a spiral body 3 driven by a motor 2, as shown in FIG. However, there is a drawback in that when the vending machine vibrates while waiting for sales, the powdered raw material falls from the raw material outlet 4.

Therefore, in order to compensate for this drawback, conventionally, as shown in FIG. Raw material export port 4 of raw material storage tank 1
By fitting the above-mentioned metal band 7 around the outer periphery of the metal band 7 and tightening it with a hand screw 6 (see Fig. 3), the prevention plate 8 prevents the raw material from spilling during vibrations, etc. .

However, in this conventional method, the raw material nozzle 5
When attaching it to the raw material outlet 4, it is necessary to tighten it with the hand screw 6 as described above, which has the drawback of very poor workability.

Furthermore, when attempting to attach a raw material chute to prevent the raw material from scattering when the raw material is discharged from the raw material outlet 4, the raw material nozzle becomes a hindrance.
It took time to install it, and rubber gaskets were required to prevent noise during vibration, which caused various problems in terms of workability and cost.

[Purpose and structure of the invention]

The present invention simplifies the attachment of the raw material nozzle to the raw material outlet, makes it easy to manufacture the raw material nozzle itself, and also allows the raw material chute to be easily and reliably attached using the raw material nozzle. A ring part that is fitted into the raw material outlet and a blocking surface part that covers approximately the lower half of the front surface of the ring part are integrally molded from a highly elastic material such as rubber, and the ring part A raw material nozzle with an engaging groove carved on the entire outer periphery of the raw material chute is provided, and this raw material nozzle is fitted into the raw material outlet using the ring portion, and is formed on the side wall surface of the raw material chute consisting of a cylindrical body with an open bottom end. The attached mounting hole is attached to the engagement groove of the ring portion.

〔Example〕

Fig. 4 is a configuration diagram showing the main parts of the powder raw material carrying out device according to the present invention, and in the figure, 11 is a powder raw material storage tank, which is equipped with a raw material carrying out port 12 at the lower part of the side wall, and at the bottom. By the rotation of the spiral body 13, the powder raw material is guided toward the raw material outlet 12 and is also discharged from the outlet 12.

Reference numeral 14 denotes a raw material nozzle integrally formed from an elastic material such as rubber, and as shown in FIGS. and a blocking surface portion 16 that covers the
Further, an engagement groove 18 is provided on the entire outer periphery of the ring portion 15.

This raw material nozzle 14 is connected to its ring portion 1.
5 is fitted onto the outer periphery of the raw material outlet 12, and in this state, the blocking surface portion 16 covers the lower half of the front surface of the outlet 12.

Reference numeral 19 designates a raw material chute consisting of a cylindrical body with an opening 20 at the lower end, and has a mounting hole 21 on its side wall surface, through which the raw material nozzle 1 can be connected.
It is designed to be attached to the ring portion 15 by being engaged with the engagement groove 18 in the ring portion 15 of No. 4.

The raw material chute 19 has an opening 20 facing a mixer 22 at the next stage.

This mixer 22 dilutes and mixes the powdered raw material from the raw material chute 19 with hot water sent through a pipe 23 from a hot water supply tank (not shown), and sends it to the next stage through a pipe 24.

Since the present invention is constructed as described above, the raw material nozzle 14 can be easily attached to the outer periphery of the raw material outlet 12 by simply fitting the ring portion 15 into the raw material outlet 12 by utilizing its elasticity. In addition, the engagement groove 18 carved on the outer periphery of the raw material nozzle 14
Since the raw material chute 19 can be attached by using the material chute, the work of attaching the raw material chute becomes extremely simple, and since the raw material nozzle 14 itself has elasticity, it acts to prevent noise during vibrations and also prevents noise from coming from the gap in the attachment part. It is possible to prevent the powder raw materials from scattering.

Further, when the spiral body 13 rotates with the raw material nozzle 14 attached, the powdered raw material is carried out from the raw material outlet 12 toward the raw material chute 19 over the blocking surface portion 16 of the raw material nozzle 14, and is transferred to the mixer 22.
On the other hand, when the spiral body 13 is stopped, the blocking surface portion 16 prevents the powder raw material from spilling out.

〔effect〕

Since the present invention is constructed as described above, it is not only easy to manufacture the raw material nozzle itself, but also the attachment of the raw material nozzle to the raw material outlet and the attachment of the raw material chute are extremely easy, resulting in extremely good workability. In addition to being inexpensive to manufacture, since the raw material chute is attached using the engagement groove carved on the outer periphery of the raw material nozzle, it not only has the effect of preventing noise during vibration, but also reduces the amount of powder raw material coming from the attachment part. This has the remarkable effect of preventing the scattering of.
