Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder dispensing device used in manufacturing porcelain products and the like.

0002

2. Description of the Related Art Conventionally, in the production of porcelain products, etc., it has sometimes become necessary to distribute powder as a porcelain material having required components and particle size into predetermined equal amounts. In such a case, a tray for distributing powder as shown in FIG. 3, that is, a powder receiving tray provided with a plurality of powder storage chambers 11 uniformly divided into squares in plan view. 10 is prepared in advance, and the powder W scooped out using a hand-held instrument 12 shaped like a so-called ladle is shaken into each powder storage chamber 11 and distributed.

Alternatively, as shown in FIG. 4, together with the powder receiving tray 10, there is also a powder supply container 13 formed in a so-called funnel shape and containing powder W, and an opening at its lowermost end (not shown). Prepare a flexible hollow tube 14 such as a rubber hose with one end connected to the
The other end of this flexible hollow tube 14 is manually applied to each of the powder storage chambers 11 of the powder receiving tray 10, and the powder W is also sprinkled therethrough.

0004

[Problems to be Solved by the Invention] However, in the above-mentioned conventional examples, not only is there a drawback that laborious manual work is required and it is difficult to achieve automation, but it is also difficult to It is difficult to evenly distribute the amount of powder W sprinkled into the body storage chamber 11, and furthermore, the powder W causes clogging in the flexible hollow tube 14, which is an inconvenience. It had become.

[0005] The present invention was devised in view of these inconveniences, and it is possible to evenly distribute powder without any troublesome effort, and moreover, it can be easily automated. The purpose of the present invention is to provide a powder dispensing device with a configuration that allows the following.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the powder dispensing device according to the present invention includes a powder supply container to which a vibration vibrator is attached, and a powder supply container disposed below the container. It is equipped with a receiving tray and a driving means for horizontally moving one of these at a constant speed,
At the lower side of the powder supply container, there is a dispensing opening that opens along the horizontal direction perpendicular to the movement direction and faces upward, while the inside of the powder receiving tray has a uniform square shape in plan view. It is characterized by having a plurality of partitioned powder storage chambers.

[0007]

[Operation] According to the above structure, a predetermined amount of powder is shaken out from the shakeout opening provided in the powder supply container by the operation of the vibration vibrator, but at this time,
Since either the powder supply container or the powder receiving tray is moved horizontally at a constant speed by the driving means, each of the powder storage chambers provided in the powder receiving tray is filled with the same amount of powder. Powder will be sprinkled in.

[0008]

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings.

FIG. 1 is a perspective view showing a schematic structure of a powder dispensing device according to this embodiment, and FIG. 2 is a sectional view showing a schematic structure of a powder supply container. It is a device. In these figures, parts and portions that are the same as or correspond to those in FIGS. 3 and 4 showing the conventional example are given the same reference numerals.

As shown in FIG. 1, this powder dispensing device 1 includes a powder supply container 2 disposed above the powder W to be distributed, and a powder supply container 2 disposed below the powder supply container 2 for storing powder W to be distributed. It includes a powder receiving tray 10 that receives powder W, and a hydraulic cylinder 3 serving as a driving means for horizontally moving the powder receiving tray 10 in one predetermined direction at a constant speed. Inside this powder receiving tray 10,
Similar to the conventional example, a plurality of powder storage chambers 11 for storing powder W are provided, which are uniformly divided into squares in plan view. By the way, as the above-mentioned driving means, it goes without saying that in addition to a pneumatic cylinder or the like, a sliding mechanism configured using a chain or the like may be adopted, and it goes without saying that the moving speed thereof can be adjusted. do not have.

A vibration vibrator 4 for vibrating the powder supply container 2 is attached via a bracket 5 to the powder supply container 2, while a powder receiving tray is provided at the lower side of the powder supply container 2. A swinging opening 6 is provided which is opened along the horizontal direction orthogonal to the moving direction of the swinging machine 10 . As shown in FIG. 2, the outlet 6 has a shape that is parallel to and spaced apart from a tongue 7 by a predetermined distance, which extends obliquely inward from the side surface of the powder supply container 2. It is made to face upward by combining with the bottom surface 8 of the powder supply container 2. Here, it is desirable that the vibration vibrator 4 and the hydraulic cylinder 3 have a configuration that can be automated so that they can operate in synchrony.

Therefore, in this powder distribution device 1, when the vibration vibrator 4 attached to the powder supply container 2 is operated to vibrate, the vibration of the vibration vibrator 4 is released from the dispensing port 6 provided in the powder supply container 2. A predetermined amount of powder W is shaken out depending on the amount. Therefore, at this time, the powder receiving tray 10 disposed below to receive the powder W shaken out is horizontally moved by the hydraulic cylinder 3 at a constant speed predetermined based on the required distribution amount of the powder W. This powder receiving tray 10
The same amount of powder is sprinkled and stored in each of the powder storage chambers 11 provided in the powder storage chambers 11.

In the above description, it is assumed that the powder receiving tray 10 is moved horizontally by the hydraulic cylinder 3, but it is also possible to configure the powder supply container 2 to be moved horizontally. Further, the powder storage chamber 11 of the powder receiving tray 10 is formed from the beginning as a separate detachable frame component, and these framework components are replaced with each other to change the bottom area of the powder storage chamber 11 in plan view. The amount of powder W to be distributed may be adjusted accordingly.

[0014]

As explained above, according to the powder dispensing device of the present invention, when the vibration vibrator and the driving means are operated together, a predetermined amount of powder can be dispensed from the dispensing port provided in the powder supply container. The body is shaken out, and the shaken out powder is received by a powder receiving tray. Therefore, the same amount of powder can be sprinkled into each of the powder storage chambers provided in this powder receiving tray without any troublesome effort. The amounts of powder stored in each are equal to each other.

Furthermore, in the present invention, since the powder supply container and the powder receiving tray are operated by using a vibration vibrator and a driving means in combination, automation of these can be easily achieved. You can also get
