Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mold for confectionery, particularly for encapsulating fondant, cream, caramel, jelly, mallow, or other soft confectionery in the center of chocolate. The present invention relates to a mold for confectionery formed by

(Prior art) With conventional molds, it is extremely difficult to eject a large number of molded pieces of soft confectionery from the mold without damaging the confectionery pieces. It is possible to use bottles, but this has the disadvantage that it is not suitable for discharging soft confections.

To solve this point, for example, British patent application no.
No. 0.699 describes non-starchy mold forming, i.e. blowing air through small holes in the base of the cavity of an open mold with the mold in an inverted position. A method is disclosed for ejecting a large number of confectionery bodies from a mold, the diameter of these through holes being approximately 0.020 inches (
0,508 mm).

The reason for using such fine holes is that the flow of liquid 1m substance tends to close some of the through holes and anchor the compact to be formed, so it is necessary to prevent such flow. It's about doing. However, drilling a large number of holes in the large number of molds used in ordinary confectionery factories has the disadvantage of causing an abnormally high cost.

Instead of the method of drilling a large number of micro holes, the British patent application no.
．． No. 078,155B discloses a method of forming a transparent hole in the base of a mold, a plug having a groove is connected to the hole, and a plug having a groove is connected to the hole. The grooves, holes, and side walls form micropores through which compressed air for mold removal flows.

(Problems to be Solved by the Invention) The conventional molds have drawbacks such as low viscosity liquid carbohydrates entering the micropores.

In view of the above-mentioned drawbacks of the prior art, the object of the present invention is to efficiently discharge a large number of molded bodies, especially those manufactured from soft liquid raw materials, from a mold without damaging the shape of the molded bodies.

[Means to solve the problem]

According to the present invention, an inverted mold is provided with a plurality of cavities open to the atmosphere, each cavity is divided by a cavity wall, and a base portion of each cavity wall is defined by an annular sealing means. It is possible to provide a mold for confectionery, which is provided with a passageway that is open, and is further equipped with a means for introducing compressed gas into the cavity.

The annular sealing means is formed by an outer end of a longitudinally movable plunger and a mold, from which an enlarged flange extends over the periphery of the cavity wall. It is configured to be superimposed on the Alternatively, it can be configured so as to be aligned on the same plane as this peripheral portion.

[Effect]

With the above configuration, the mold cavity can hold the injected II substance liquid until the raw carbohydrate liquid solidifies, and also facilitates the mold removal of the product at least after the mold is turned upside down. It is composed of

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, numeral 1 denotes a mold disposed in a substantially horizontal direction, and has a plurality of shapes selected according to the shape of the soft confectionery to be molded. A lateral arrangement of molding cavities 2 is provided.・When looking at cavity 2 from above, cavity 2
A two-stage flow passage, ie, a through passage 4, is formed by penetrating the cavity wall located approximately in the center of the cavity wall, and is comprised of a large-diameter hole wall 5 and a concentrically positioned small-diameter hole wall 6. The upper end of the molding cavity 2 is open to the atmosphere. As explained below, the mold 1 is turned upside down by the turning mechanism 25 shown in FIG.

The axially movable plunger 7 made of synthetic resin is movable within the cavity 5 which has a sufficient gap in the radial direction between the plunger 7 and the mold 1 over substantially the entire length of the plunger 7.

In the illustrated case, the plunger 7 is located at the center of the lower part of the cavity 2, but if more than one plunger is used, it may be set eccentrically.

The outer end of the plunger 7, that is, the part facing the cavity 2, is circular, and its outer end face 10 faces toward the cavity 2. An annular annular protrusion 11 is formed on this end surface portion 10, a cylindrical central portion 12 operates inside a small diameter hole portion defined by a hole wall 6, and a truncated conical plunger portion 13. The inner end portion including the inner end portion extends to the inner insertion portion 14 and operates within the large diameter hole defined by the mold wall 5.

The truncated conical compression spring 15 includes an annular portion 27 coaxially abutted on the surface of the stepped portion 16 formed between the mold walls 5 and 6, and an annular enlarged portion 17 at the tip of the insertion portion 14. It acts between.

This spring 15 presses the annular sealing protrusion 18 of the annular protrusion 11 towards the cavity wall 3 in point contact, thus forming an annular seal between the outer side @8 of the plunger 7 and the cavity 3. This prevents m-trade from flowing from the cavity 2 to the hole 4. A plurality of perforations 28 are formed in the disc 27 and arranged in an annular manner.

The inner surface of the annular protrusion 18 is formed at an angle of approximately 70° with respect to the vertical direction, and an annular extension space is formed between the annular protrusion 18 and the cavity wall 3 .

In order to save molding material and facilitate molding, the plunger 7 is formed with an axial hollow portion 19.

To explain the operation of this mold, a liquid carbohydrate material is injected into the open cavity 2 of the mold 1. When the material has sufficiently solidified, the mold is inverted, ie, turned upside down.

As discussed below with respect to FIG. 4, 20-50 bonds/inch (1,406-4.218 kg/cm2) of compressed air is applied to each inverted plunger 7.

The plungers 7 are each pressed against the spring 15 in accordance with the air pressure, the protrusion 18 is separated from the cavity wall 3, and an annular jet of air enters the cavity 2 through the cavity 5.6. The compressed air is passed through a truncated conical plunger part 1.
3 and enters into the narrow space below the end surface 10. The plunger 7 thus moves from the first closed position to the second open position.

The mold 1 is reversed to an inverted position by the reversing mechanism 25 shown in FIG.

Uniformly distributed annular air is blown out from between the annular protrusion 11 and the cavity wall 3. As a result, a relatively large annular release action is initially applied in a certain manner, so that a good separation of the solidified confectionery from the cavity 3 can be achieved. Even a slight protrusion of the head 8 into the mold cavity 2 can facilitate the initial demolding of the product. The diameter of this head 8 is quite large (10 mm)
This can also prevent damage to the molded confectionery.

The disk 27 abuts against the mold 1 and thus limits the axial movement of the plunger 7. By setting the diameter of the through hole 27 to an appropriate size, the air pressure acting on the plunger 7 can be made sufficiently uniform.

FIG. 2 shows another embodiment, in which the numbers of each part are indicated corresponding to those in FIG. As shown, in the retracted position of the plunger 7, its outer end surface 10 is approximately flush with the peripheral portion of the cavity wall 3, so that the annular protrusion 1
The work is an inverted circle fi leading to hole 4! inside the h-shaped recess,
This truncated conical recess is defined by a truncated conical wall 21 . The annular lower surface 22 of the annular protrusion 11 is formed into a truncated cone shape that substantially corresponds to the inclined surface 21, so that when the plunger 7 is in the retracted position, the annular protrusion 11 and the mold 1 are in contact with each other. An annular point contact seal is formed therebetween. This forms an extended annular space.

The two surfaces 21.22 are at an angle of 20° to 7
0'' and the difference angle can be approximately 2°. The optimal value is 45° for the surface 22.

Similar to the embodiment shown in FIG. 1, compressed air is supplied via a pre-pressurization chamber as the case may be, and a substantially radially outward airflow is ejected from the annular protrusion 11 into the inverted mold 1. The plunger 7 is moved against it. Compressed air is blown out along the mold wall 3 from the annular protrusion, which is now in the lower position due to the reversal, so that a continuous mold release action is generated.

As shown in FIG. 2, the external structure 10 is arranged approximately at right angles to the cavity wall 3, thereby minimizing the stress applied to the confectionery during the solidification process.

Note that other gases can be used instead of air.

The mechanism 25 shown in FIG. 3 for inverting the mold is as follows:
This method is the same as that described in British Patent Application No. 1.473,906.

This reversing mechanism 25 is moved along an endless path by an arrow 41.
A chain-type conveyor 40 is provided to continuously move the mold 1 in the direction. The mold 1 first passes below the m-quality material supply hopper 42 to fill the mold cavity, and then passes through the cooling tank 43.

After cooling, the mold 1 is conveyed in the opposite direction to the arrow 41 along the bottom row of the conveyor 40 while being overturned.

The inverted mold 1 'it passes under a movable air supply device 44, at which time air is injected into the mold cavity 2 (injected into the mold cavity 2) and the confectionery article 45 is discharged from the mold 1 onto an endless belt 46, or as shown in the figure. It is inserted into a storage tank width that is not covered.

If necessary, a movable confectionery head attachment drop 47,48 is attached. For example, it is applicable to attaching cherry 47 to confectionery 45 and filling it with 48.

4 and 5 are detailed views of the timely air supply device 44 in FIG. 3, which uses the plunger 7 of the type shown in FIG. , shows how the device 44 operates.

The air supply device 44 includes a piston-shaped sealed housing 56 that is slidable in a cup-shaped guide tube 57 fixed to a support plate 58.
Equipped with

In particular, as shown in FIG. 4, a central through hole 59 is formed in the sealing housing 56 and communicates with a lower horizontal passage 60C. The horizontal passage 60 is bored in the diameter-cup of the boss-like protrusion 64 of the housing 56. A flexible air supply tube 61 is attached to the -L end of the housing 56 by a circular clip 62.

A compression spring 63 is resiliently disposed inside the guide tube 57, thereby pushing the lower end protrusion 64 of the housing 56 onto the support plate 58.
force downward in the direction away from the

A flexible sealing ring 65 is disposed around the lower end protrusion 64.

Furthermore, the air supply device 44 is operated in a cylinder 71 with a flexible air supply pipe 72, 73 attached thereto, as shown in FIG.
Equipped with electrically operated pneumatic piston 704, piping system 72.7
3 is further connected to a compressed air source 74.

The cylinder 71 is attached to a mounting frame 75, which is supported by pivot rods 76, 77 mounted between the frame 75 and the fixed part 78. The mounting frame 75 can therefore pivot about the pinpoint centerline 79.80.81.82 as indicated by the arrows 85.86.

The support plate 58 is connected to the lower end of the rod 90 of the piston 70 via a rotation joint 91.

The mounting frame 75 has a frame drive rod 92 movable substantially horizontally by a bell crank 93 rotatable around an axis 94.
is driven in the left-right direction.

A cam abutting body 95 that abuts the outer periphery of a cam 96 rotating around an axis 97 is supported at one end of the bell crank 93 . The other end of the bell crank 93 is a pin joint 9
8, it is rotatably connected to the drive rod 92.

The cam 96 is driven by the same drive means 99 that drive the conveyor 46, for example an electric drive means.

Timing and control valves 100 . Actuation operates according to a fixed timing sequence.

To explain the operation below, the mold 1 is connected to the air supply device 44.
When passing under the cam 96 and attached members,
Within the limits defined by the pivot rods 76.77,
The support plate 58 moves in a fixed timing sequence with the mold.

At the same time, the support plate 58 moves the piston 70 at a certain timing.
The plunger 7 is moved downward until the lower surface of the lower end protrusion 64 in FIG. 4 abuts the upper end of the plunger 7, and then moved downward as shown. Next, air hose 61, vertical hole 59
Compressed air is injected into the cavity 2 at appropriate times through the horizontal path 6o. Due to the action of the spring 63, the sealing body 65 in contact with the disk 27 prevents air from escaping.

By coming into pressure contact with the mold 1, the disc 27 simultaneously limits the downward movement of the plunger 7.

After air is injected into the cavity 2, the support plate 58 is first pulled up, and then the next mold 1 arrives.

The air supply device 44 shown in FIGS. 4 and 5 preferably uses a combination of mechanical force and air pressure to move the plunger.

In other embodiments, the lower end protrusion 64 may be shortened so that it does not contact the head of the plunger 7. In this case, the plunger 7 is moved entirely by air pressure.

In still other embodiments, the plunger movement can be performed entirely mechanically without the use of the air supply hose 61 and by using the sealed housing 56.

A combination with mechanical drive or pneumatics is particularly suitable for the discharge of less soft carbohydrate products.

If necessary, a configuration in which the disk 27 is omitted is also possible.

In addition, 1. As a modification not shown in FIG. 2, an auxiliary plate and an attached mechanism can be added to the base surface of the mold 1, and a preload chamber can be added. In this case, pressurized air can be introduced into the prepressure chamber and supplied to the plurality of plungers 7 using, for example, the air supply #74 and the air supply hose shown in FIG. According to this method, when the mold 1 is inverted, the plunger 7 is pressed down only by air pressure.

Various other modifications are possible, and any of them fall within the scope of the claims of the present invention as long as they do not depart from the technical idea of the present invention.

(Effects of the Invention) With the above-described configuration of the mold of the present invention, during the injection of the m-quality stock solution, the communication hole for the compressed gas for discharging the molded body is completely sealed, and the stock solution does not enter. When the mold is turned upside down after the assimilation of carbohydrates, the sealing of the flow holes is released and the gas is ejected in an annular shape, allowing for smooth release from the mold without damaging the molded confectionery. can be done.

In addition, since there is no need to form fine holes or the like in the mold itself, there is an advantage that the mold can be easily worked.
