Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a rice cake filling device used when manufacturing packaged rice cakes.

(Prior art) Conventionally, there has been a known manufacturing method in which softened mochi is filled and packaged in a packaging film formed into a certain shape, such as Osonae mochi, and then left to harden to form a packaged mochi. There is.

In this case, the filling of mochi is carried out by extruding the mochi from a filling nozzle, and receiving the extruded mochi with a formed packaging film at the end of the nozzle. After filling is completed, the opening of the packaging film is closed with a lid plate. I tried to keep it sealed.

(Problem to be solved by the invention) In the rice cake filling operation described above, if filling is continued with the filling nozzle and the packaging film facing each other at a fixed interval, a cavity will remain in the concave part of the packaging film. There were many problems. The rice cake extruded from the filling nozzle is filled while flowing toward the bottom of the recess, but the rice cake is highly viscous and it is difficult to make it conform to the inner wall of the recess of the packaging film immediately after filling. It is for this purpose.

In order to fill the above-mentioned cavity so that it does not remain,
From the start to the end of filling, it was necessary to change the distance between the filling nozzle and the packaging film to reduce the amount of rice cake flowing.

As a means of changing the distance between the filling nozzle and the packaging film, a configuration was considered in which a lifting device was installed so as to straddle the passage area of the packaging film, and the filling nozzle was mounted on the lifting device side, but the lifting and lowering operation was not possible. At the point where the packaging film passes under the lifting device,
There were concerns about hygiene issues.

(Means for solving the problem) Therefore, this invention enables the filling nozzle to be raised and lowered using a lifting device installed outside the passage area of the packaging film, thereby making it possible to perform automatic filling without leaving any cavities.

That is, in the rice cake filling device of this invention, a plurality of rows of rice cake filling portions are formed at regular intervals in the transport direction on a packaging film that is continuously transferred by an intermittent transfer device. A mochi filling device in which a filling nozzle facing toward the top is mounted on an elevating device, the elevating device being installed outside the passage area of the packaging film, and filling nozzles corresponding to the plurality of rows of mochi filling portions. , are characterized in that they are placed one pitch apart in the direction of travel of the packaging film.

(Function) According to the rice cake filling device of this invention, the distance between the filling nozzle and the packaging film can be changed via the lifting device. As a result, the rice cake can be packaged so that no cavity remains in the rice cake filling portion formed in the packaging film. The filling nozzle lifting device is installed outside the packaging film passage area, so
Hygiene problems such as contamination of packaging films can be avoided.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a packaging film, and as shown in FIG. 2, three rows of rice cake filling parts 2, 2 each consisting of a concave part are formed at regular intervals in the longitudinal direction. This packaging film 1 is intermittently transferred in the direction of arrow 3 by an intermittent transfer device (not shown), with the interval between the rice cake filling portions 2, 2 being one pitch. There is.

A base 4 is provided outside the passage of the packaging film 1.
is installed at an angle with the passage part, and the base 4
Extruder 5 is mounted on top. The extruder 5 has a motor 6 for rotating the screw.
and a hopper 7, and a T-shaped conduit 8 is connected to the extrusion port.

The base 4 has four corners with fluid pressure cylinders 9,
9 constitutes an elevating device 21, and the fluid pressure cylinders 9, 9 are connected to a pressurized fluid supply/discharge device 10.
By driving the extruder 5 through the base 4, the extruder 5 supported on the base 4 can be moved up and down together with the T-shaped conduit 8, the motor 6, etc.

Three filling nozzles 11 are vertically installed below the horizontal conduit 8a of the T-shaped conduit 8. This filling nozzle 11 is arranged to face the rice cake filling section 2 when the intermittent transfer of the packaging film 1 is stopped. The horizontal conduit 8a is connected at right angles to the base tube 8b of the T-shaped conduit 8, and forms an angle with the packaging film 1, so that the filling nozzles 11, 11 facing the rice cake filling parts 2, 2 are They face each other with a one-pitch offset in each column.

12 in the figure is a hot water circulation pipe provided outside the hopper 7 and the T-shaped conduit 8. The hot water circulation pipe 12 is provided for the purpose of keeping the rice cakes in the hopper 7 and the T-shaped conduit 8 warm by circulating hot water in the circulator 13.

Further, numeral 14 in the figure is a mochi cutting blade that faces one side of the tips of the filling nozzles 11, 11. The mochi cutting blade 14 is made to reciprocate in the direction of the arrow 15 when the filling nozzle 11 is at its highest position, and is supported by a piston rod 17 of a fluid pressure cylinder 16 for this reciprocating movement.

In the embodiment described above, during the intermittent transfer of the packaging film 1, the filling nozzle 1 is
1 and 11 to a predetermined position, and then raise the nozzle while filling it with mochi. Since the mochi is filled sequentially from the lowest part of the mochi filling parts 2 and 2, the mochi and the inner wall of the mochi filling part are It is possible to fill the gap without creating a cavity.

That is, when the base 4 is lowered via the fluid pressure cylinders 9, 9 while the packaging film 1 is stopped, the filling nozzles 11, 11 are also lowered, and as shown in FIG. The tip portion can be inserted into the portion 2. Therefore, by driving the motor 6, the extruder 5 pushes out the rice cake in the hopper 7 toward the filling nozzles 11, 11, and the base 4
When the filling nozzles 11, 11 are moved in the direction away from the mochi filling portions 2, 2 by raising them with the fluid pressure cylinders 9, 9, the filling nozzles 11, 1
The rice cakes 18 extruded from the rice cake filling section 2 are filled sequentially from the bottom (in the figure) to the upper opening, and filling can be completed without waiting for the rice cakes 18 to flow. It is possible to avoid leaving a cavity between 18 and the inner wall of the rice cake filling part 2.
It goes without saying that the moving speed of the filling nozzle 11 and the amount of rice cake 18 extruded by the extruder 5 are set depending on the shape and size of the rice cake filling section 2. In FIG. 3, 19 is a receiving plate that supports the rice cake filling section 2 from below, and 20 is a regulating plate.

As described above, when the filling of mochi is completed and the filling nozzles 11, 11 reach the highest position, the motor 6 is stopped to interrupt extrusion by the extruder 5, and the mochi cutting blade 14 is The extruded rice cake 18 is transferred to the filling nozzle 1 by moving it back and forth twice.
It is best to cut at the tip of 1.

Thereafter, by transferring the packaging film 1 one pitch at a time and repeating the same operation as above, the mochi filling parts 2, 2 of the packaging film 1 are continuously filled with mochi without leaving any cavities. can do.

Another film is placed over the filled packaging film 1 from the opening side of the rice cake filling section 2.
Sealing is achieved by heat welding them together.

In the above embodiment, when the extruder 5 and the filling nozzle 11 are raised and lowered by the lifting device 21, even if dust or the like falls or scatters from the base 4, the lifting device 21 can be moved up and down by the packaging film. Since the packaging film 1 is installed outside the passage section of the packaging film 1, contamination of the packaging film 1 can be avoided.

Moreover, since the plurality of filling nozzles 11, 11 are shifted by one pitch with respect to the plurality of rows of rice cake filling parts 2, 2, the T-shaped conduit 8 can connect the horizontal conduit 8a and the base tube 8b at right angles. This makes it possible to smoothly flow the rice cake in the portion, and to introduce substantially uniform rice cake to each filling nozzle 11, 11. Furthermore, the filling nozzle 11,1
The surrounding space of filling nozzle 11, 11 can also be widened.
It is advantageous in that it is easy to adjust and clean, and it is easy to monitor the rice cake filling section from the front side of the device.

(Effects of the invention) As explained above, according to this invention, the filling nozzle facing the mochi filling part of the packaging film that is intermittently transferred is moved toward and away from the mochi filling part. It can be filled without leaving any cavities, and it also enables continuous automatic filling, which has the effect of significantly improving work efficiency.

Furthermore, since the lifting device for lifting and lowering the filling nozzle is installed outside the passage of the packaging film, there are sanitary effects such as ensuring cleaning of the packaging film.

Furthermore, as a result of shifting the plurality of filling nozzles one pitch to the rice cake filling section in multiple rows, the flow of the rice cake extruded from the extruder side to each filling nozzle is made smooth and even, and the rice cakes in each row are filled. In addition to being able to fill the mochi evenly into the area, the space around the filling nozzle can be widened, making it easier to adjust, clean, and clean the filling nozzle.
This has the effect of making monitoring easier.
