Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a metering device for dispensing confectionery dough and the like.

[Conventional technology and its problems]

Conventionally, this type of fixed-quantity dispensing device has a disc-shaped rotating cylinder connected directly below the hopper so as to rotate intermittently and communicate with each other, and a large number of piston bodies arranged radially within the rotating cylinder. It is known that a piston body is reciprocated through a plate cam attached to the rotating shaft of a rotating cylinder, and a fixed amount of confectionery dough or the like is filled and discharged (Japanese Patent Application Laid-Open No. 164834/1983, Kosho 56-
(See Publication No. 21257).

Although the above-mentioned conventional example can always uniformly dispense a fixed amount of confectionery dough, etc., it has a very complicated structure because each piston body is reciprocated by a cam mechanism installed in a rotating cylinder.
Not only is it troublesome to manufacture, but the device as a whole tends to be large-sized. Furthermore, since the structure is extremely complex, it inevitably causes serious problems in terms of maintenance and management.

This idea aims to solve the conventional problems and provide a practical metered dispensing device that has an extremely simple structure, can reliably reciprocate the piston body, and can always dispense a constant amount. .

[Means for solving problems]

That is, in this invention, a rotary cylinder 5 is connected directly below the hopper 1 so as to rotate intermittently and communicate with the rotary cylinder 5, and a piston body 7 is installed in the rotary cylinder 5 to fill and discharge a fixed amount of confectionery dough or the like. In a quantitative dispensing device for confectionery dough or the like, the piston body 7 has its piston rod 8 loosely inserted perpendicularly to the rotation shaft 6 of the rotary cylinder 5, and the piston rod 8 is inserted at both ends of the piston rod 8. A piston member 9 which also serves as a stopper is attached to each of the piston members 9, and the piston body 7 is reciprocated by its own weight in conjunction with the operation of the rotary shaft 6, and is configured to perform quantitative filling and discharging.

[Effect]

While rotating the rotating cylinder 5 intermittently, the piston body 7 is automatically reciprocated by its own weight in conjunction with the operation of the rotating shaft 6. Then, due to the reciprocating action of the piston body 7, one piston member 9 also moves the confectionery dough A from the hopper 1 into the rotating cylinder 5.
etc., and the other piston member 9 is also used to discharge the confectionery dough A, thereby synchronously and continuously performing quantitative filling and discharging of the confectionery dough A, etc.

〔Example〕

An embodiment of this invention shown in the drawings will be described below.

1 and 2 show the first embodiment,
In the figure, 1 is a hopper, and 2 is a pair of extrusion rollers installed inside the lower end of the hopper 1, and the extrusion rollers 2 rotate synchronously in opposite directions. Reference numeral 3 denotes a nozzle plate horizontally disposed at the lower end of the extrusion roller 2 via a guide tube 4, and 5 a substantially disc-shaped rotating cylinder disposed at the lower end of the nozzle plate 3 so as to rotate intermittently and communicate with the nozzle plate 3. , 6 is a hollow rotating shaft inserted into the rotating cylinder 5, 7 is a piston body inserted through the rotating shaft 6 and loosely mounted in the rotating cylinder 5, and the piston body 7 is connected to the rotating shaft 6. The piston rod 8 is loosely inserted into the piston rod 8, and a pair of piston members 9 which also serve as stoppers are attached to both ends of the piston rod 8, respectively.
The piston body 7 is interlocked with the intermittent rotation of the rotary cylinder 5, and is regulated by the operation of the rotary shaft 6, and reciprocates with a required cylinder volume due to its own weight. Reference numeral 10 indicates a conveyor disposed below the rotating cylinder 5, and A indicates confectionery dough.

Next, the operation of the apparatus configured as described above will be explained.

First, the kneaded confectionery dough A is put into the hopper 1. At this time, one end hole of the rotating cylinder 5 is communicated with the lower end of the hopper 1 via the nozzle plate 3, the piston body 7 is lowered by its own weight, and the upper piston member 9 is brought into contact with the rotating shaft 6. It is positioned at bottom dead center. After that, when the extrusion roller 2 is rotated, the confectionery dough A is
is extruded downward by the extrusion roller 2, passes through the nozzle plate 3, and is filled into the rotary cylinder 5. When filling of the confectionery dough A is completed, the rotating cylinder 5 starts rotating in the direction indicated by the arrow in FIG. At this time, the confectionery dough A filled in the rotating cylinder 5 is
As the rotating cylinder 5 rotates, only the required confectionery dough A is held in the rotating cylinder 5 as it is scraped off by the hole edge of the nozzle plate 3. Then, the rotating cylinder 5 stops its rotational operation when it has rotated 180 degrees. Then, the piston member 9 located at the upper part starts to descend in conjunction with the pressing of the confectionery dough A, and as the confectionery dough A is filled into the rotary cylinder 5, the piston member 9 located at the lower part also moves down in conjunction with the confectionery dough A.
The confectionery dough A held in the rotating cylinder 5 is extruded and discharged.

Thereafter, in the same manner, the rotating cylinder 5 is intermittently rotated, and filling and holding and discharging of a predetermined amount of confectionery dough A are performed synchronously and continuously.

3 and 4 show the second embodiment,
The difference from the first embodiment is that the extrusion roller 2 in the hopper 1 has been removed, and that the rotary cylinder 5 is airtightly housed in a cylinder case 11 having communication holes 12 at the top and bottom; other parts are the same. , and the same reference numerals indicate the same parts. And such a device
Mainly, as shown in the drawings, it is suitable for discharging a fixed amount of liquid B as well as a fixed amount of lumps, granules, and the like.

In the above embodiment, the rotary cylinder 5 has a substantially disk shape, but is not limited to this shape, and may be formed in a substantially cylindrical shape. Further, in order to assist the reciprocating movement of the piston body 7, compressed air or the like may be used. Furthermore, the device according to this invention can be applied not only to confectionery dough but also to dispensing similar materials.

[Effect of idea]

Since this idea is structured as described above,
While rotating the rotary cylinder 5 intermittently, the piston body 7 is automatically reciprocated by its own weight in conjunction with the operation of the rotary shaft 6, and one piston member 9 moves the confectionery dough A from the hopper 1 into the rotary cylinder 5. It is capable of filling a fixed quantity of confectionery dough A, etc., and discharging it with the other piston member 9, so that the fixed quantity filling and discharging of confectionery dough A, etc. can be carried out synchronously and continuously. By reciprocating the piston body 7 without using it, it is possible to always ensure uniform and constant discharge. Furthermore, this invention has an extremely simple configuration, and not only can it be easily manufactured, but also allows the device itself to be made more compact.
