DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method and apparatus for filling a fluid molding material into an elastic mold according to the present invention will be described below with reference to the accompanying drawings. In addition, as the fluid filler,
As mentioned above, in order to obtain chocolate confectionery as a molded product, ice confectionery, jelly confectionery, butter, food such as cheese and daily necessities such as eraser, soap, wax, gypsum, concrete, etc., it was initially liquid Although various can be solidified into a solid by cooling, heating, etc., according to the method and the apparatus of the present invention, since any filler can be similarly filled, in this embodiment, as a typical filler,
Only the case of a fluid chocolate material for obtaining chocolate confectionery will be described as an example, and the case of other fillers will be omitted.

First, inject a fluid chocolate material
An elastic molding die 10 comprising a film-shaped product molding part 1 for obtaining a chocolate molded product having a rose flower shape by filling and a mold holding part 2 continuous with an outlet 3 at an end of the molding part 1 is provided. It is fixed to the mold mounting plate 4 of an automatic continuous chocolate molding device (not shown) so that the outlet 3 opens downward. A pressurizing / depressurizing chamber 5 is maintained above the elastic mold 10, and a tempering temperature of about 26 to 32 ° C. is maintained below the outlet 3. For example, a cacao oil or a cacao substitute oil or a fluid oil or fat. Alternatively, the container 7 containing the oil / fat, the fluid chocolate material, and the mixture 6 is put on standby (see FIG. 1A).

The elastic molding die 10 has a uniform thickness at the outer angle of the take-out port 3 of the product molding section 1, that is, the outer side where the product molding section 1 and the mold holding section 2 intersect, and is formed into a curved arm. Therefore, the product molding portion 1 has a concavo-convex pattern 1a for making rose-flower-shaped concavities and convexities in the molded product. The pressurizing / depressurizing chamber 5 is provided in a cylindrical chamber main body 5a that can move up and down, and is provided above the chamber main body 5a, and is connected to a pressurizing source (not shown) and a depressurizing source (not shown), respectively. consists of a air supply pipe 5b and the air discharge pipe 5c, the opening edge portion 5a ₁ of the chamber body 5a has rounded.

The mixing ratio of the fats and oils of the mixture 6 and the fluid chocolate material is not particularly limited as long as a thin oil film can be formed on the inner surface of the product molding portion 1 as described later,
It has been found that it is preferable that about 15% of the total amount of the chocolate material is contained in consideration of the adhesiveness with the chocolate material at the time of filling, which will be described later, but only the fat or oil may be used. Further, the oil or fat or the mixture 6 of the oil and fat and the chocolate material in the above temperature range is preferable because it easily adheres to the uneven pattern 1a on the inner surface of the product molding portion 1, but the oil or fat or the mixture of the oil and fat and the chocolate material outside the above temperature range is preferable. 6
However, the temperature of the oil or fat or the mixture 6 of the oil and fat and the chocolate material is not limited because it adheres to the uneven pattern 1a.

Next, the pressurizing / depressurizing chamber 5 is moved downward, the product molding portion 1 is surrounded by the chamber body 5a, and the die holding portion 2 can be pressed from the outer surface of the die 10 by the opening edge 5a ₁ of the chamber body 5a. (See FIG. 1B).

After that, by further moving the pressurizing / depressurizing chamber 5 downward, the inner surface of the mold 10 is pushed to a position slightly above the container 7, the mold 10 is extended, and the outlet 3 is expanded (see FIG. 2 ( See a)).

Then, the mold 10 is pressurized and expanded by the air supplied from the air supply pipe 5b to the chamber 5, and the mold 10 is expanded.
The product molding part 1 of 1 is immersed in the oil or fat or the mixture 6 of the oil and fat and the chocolate material in the container 7 (see FIG. 2B). At this time, the pressurizing / depressurizing chamber 5 repeats a slight pressurization and release thereof to give a fine vibration to the product molding portion 1 (see FIG. 2).
(See (c)). As a result, while air remaining in the uneven pattern 1a and between the fat or oil or the mixture 6 of the fat and oil and the chocolate material 6 is diffused, the fat or oil or the mixture 6 of the fat and chocolate material 6 is added to the product molding portion. It is attached to the inner surface of 1 in the form of a thin oil film. Incidentally, the viscosity of the chocolate material is generally 30,000 to 50,000 Hoise,
When only this is attached to the mold 10, air is left in the uneven pattern 1a to form blocking. Therefore, by mixing the fat and oil with the chocolate material and reducing the viscosity to 2000 to 3000 hoise, the mixture 6 forms a thin oil film in the entire uneven pattern 1a without leaving air in the uneven pattern 1a, that is, without forming blocking. Adhere to. Further, the mixture 6 attached in the form of an oil film having a low viscosity is absorbed by the chocolate material to be filled in the filling step described later, homogenized and integrated.

Next, the pressurization by the pressurizing / depressurizing chamber 5 is stopped, and the air in the chamber main body 5a is exhausted from the air exhaust pipe 5b, so that the mold 10 is sucked under reduced pressure and the pressurizing / depressurizing chamber 5 is moved upward. (See FIG. 3A).

Then, by further moving the pressurizing / depressurizing chamber 5 upward, the mold 10 is returned from the state in which the pressurizing / depressurizing chamber 5 is pressed to expand the take-out port 3 (see FIG. 3 (b)).

After turning the returned mold 10 upside down, it is moved to a position below the filling device 8 and stopped by a conveyor device (not shown) of an automatic continuous chocolate molding device (FIG. 4 (a)).
reference).

Then, the filling device 8 is lowered, the lowering of the filling nozzle 8a is stopped at a position slightly above the product forming section 1, and the fluid chocolate material 6'is filled in the product forming section 1. According to the electrostatic sensor 9 attached near the tip of 8a, a certain amount is filled (see FIG. 4B), and then the filling device 8 is moved upward (see FIG. 4C).
The electrostatic sensor 9 has an oscillating circuit that starts and stops oscillation according to a change in capacitance, and an open / close element that is turned on / off by an oscillating signal of the oscillating circuit. As shown in, the distance H ₁ (distance from the mounting position of the mold holding unit 2 to the boundary surface between the product molding unit 1 and the mold holding unit 2) and the distance H ₀ (mounting position of the mold holding unit 2 from the electrostatic sensor 9 To the lower end surface of the electrostatic sensor 9 and the set distance Ha (the distance from the lower end surface of the electrostatic sensor 9 to the boundary surface between the product molding unit 1 and the mold holding unit 2), the set distance Ha is detected. The filling device 8 is operated to fill a certain amount until the distance becomes equal to the distance Hb (distance from the lower end surface of the electrostatic sensor 9 to the filling surface).

Next, a process for obtaining a molded product from the elastic molding die filled by the method of the present invention will be briefly described as an example.

After moving the filling device 8 upward (see FIG.
(See (c)), the filled mold 10 is solidified by a solidifying device, for example, about 4
It is transferred to a cooling tunnel (not shown) kept at -7 ° C by a conveyor device (not shown) and cooled and solidified for 10 minutes.

The elastic molding die 10 is inverted from the state of FIG. 4 (c) so that the outlet 3 thereof opens downward,
The pressurizing / depressurizing chamber 5 is made to stand by in advance above the mold 10 (see FIG. 6).
(See (a)).

Next, the pressurizing / depressurizing chamber 5 is moved downward so that the chamber body 5a of the chamber 5 surrounds the product molding portion 1 and the opening edge 5a ₁ of the chamber body 5a allows the die holding portion to be held from the outer surface of the die 10. 2 is positioned so that it can be pressed (see FIG. 6B).

Thereafter, by further moving the pressurizing / depressurizing chamber 5 downward, the inner surface of the mold holding portion 2 is extruded downward, the mold 10 is extended, and the outlet 3 is expanded (FIG. 6).
(See (c)).

By supplying air to the chamber 5 from the air supply pipe 5b, the mold 10 is expanded under pressure, and the oil film of the fat or oil or the mixture 6 of the fat and the chocolate material solidified from the product molding portion 1 of the mold 10 is solidified. Is peeled off, that is, the molded product is released from the mold to manufacture a three-dimensional decorative chocolate product 11 (molded product) having a rose flower-shaped pattern (see FIG. 6D). Three-dimensional decorative chocolate product 11 (molded product)
Since the inner and outer surfaces of the mold 10 that has been released are reversed, the mold 10 is sucked again by the pressurizing / depressurizing chamber 5 and returned to the original state. Also, at the time of release, a fat or oil or a mixture of fat and a chocolate material 6
The oil film of No. 3 is cleanly released from the mold 10 made of an elastic material without adhering to and remaining on the mold 10. This means that the fat or oil or the mixture 6 of the fat and chocolate material adheres to the chocolate material 6'side. ..

[0033]

According to the method and the apparatus of the present invention, by pressing from the outer surface of the elastic molding die, the take-out port of the mold is expanded, and the expanded mold is pressure-expanded. The product molding part is immersed in advance in a fluid oil or fat or a mixture of the oil and fat and a fluid filler in the container, and this fluid oil or mixture of the oil and fat and the fluid filler is attached to the product molding part. Therefore, when filling the filling material, a fluid oil or a mixture of the oil and fluid and a filler is deposited in a thin film inside the uneven pattern of the elastic mold, and air is trapped in the uneven pattern. It can be filled with a fluid filler so that it does not remain, and therefore the surface of the molded product released from this mold is covered with an oil film consisting of fluid oil or fat or a mixture of the oil and fluid filler to give gloss. Molding with a smooth surface It is possible to obtain.

Further, the product forming part is finely divided by repeating the pressurization / pressurization while the product forming part is immersed in the fluid oil or fat in the container or the mixture of the oil and the oil and the fluid filler. If it is vibrated to the inside,
