Description

Description Filling and molding machine

Technical field

The present invention relates to a filling molding machine, and more particularly, to an elastic filling mold having an opening bag-like filling portion, a non-solid filling material, for example, water or kneading. It is filled with food items such as chocolate, kamaboko, hammire, etc., stationery items such as eraser, or daily necessities such as stone. , Which is related to a filling molding machine for solidification molding

冃 Landscape technology

Conventionally, for foodstuffs, filled products have been produced using filled molds without any doubt as to other foodstuffs.

Such a conventional filling mold has been formed from a plurality of divided molds composed of projectiles corresponding to the shape of the filling molded article. In such a filling mold using a conventional split mold, a filling material is filled in the inside of these split molds, and the filling material is solidified inside the split mold. However, it was taken out by dividing the split type.

However, filled products manufactured using such conventional filling molds are manufactured using split molds. As a result, the commercial value of the manufactured molded products has been reduced.

In addition, in order to manufacture a molded product having a particularly complicated shape, a large number of split molds are required, and the production process has been complicated.

Furthermore, since the split-type body was formed as a single body, the manufacture of the split-type body itself was also expensive, which had a great effect on the product cost. And it was. In particular, in the case of high-mix low-volume production, the cost of split-type products occupies a large amount in the cost of the whole molded product, and it is not always possible to actually manufacture it. I was. In addition, when a conventional rigid split-type filling is used, in the case of packing that increases or decreases in volume when it is solidified, it is necessary to apply pressure or depressurization in the solidification process. In some cases, the split filling mold was damaged.

Here: *: The invention is based on the use of an elastic filling type that has an open bag-like filling type as the filling type.塡 In addition to being able to manufacture molded products, the cost of manufacturing the filling mold itself is reduced, and the damage to the filling mold is prevented. At the same time, the manufacturing process is greatly simplified. The purpose of the present invention is to provide a filling molded article manufacturing machine capable of filling a filling material into an elastic filling mold so that bubbles are not generated irrespective of the viscosity of the filling material. Target.

Disclosure of the invention

In order to solve the above-mentioned problems, the present invention is directed to an elastic filling mold having an opening bag-like filling portion, from a filling nozzle to a non-solid filling. A filling device for filling the material, a solidifying device in the elastic filling mold for the filling material, and a solidifying device from the filling portion of the elastic filling type. The filling device is formed from the extraction device that takes out the filling material. The filling device is suctioned with negative pressure from the anti-filling nozzle side, and the elastic filling mold is expanded before filling starts. It is characterized by being formed like a surreal.

First, the filling molded article manufacturing machine according to the invention of the present invention fills the elastic filling mold with the filling material by the filling device.

This elastic filling type is used for filling or solidifying a filling material by expanding or contracting the whole in a filling device or a drawing device. Elastic materials are used because they need to be removed.

The filling of the inside of the elastic filling mold is performed so that the air bubbles inside the elastic filling mold do not remain.

In this case, if the packing is low in viscosity like water, etc., or if the shape of the elastic packing is very simple, the packing is The filling can be performed directly from the nozzle into the elastic filling mold. However, when the filling material has a high viscosity, or when the shape of the elastic filling type is complicated, the filling nozzle is changed from the filling nozzle to the elastic filling type. If the inside is filled with the packing material, air bubbles are mixed.

Therefore, in the present invention, the elastic filling mold is expanded from the normal state before the filling is started, and after the filling of the predetermined amount of the filling material, the filling is gradually performed. By controlling the elastic filling mold to return to the normal size, the filling material is not completely filled inside the elastic filling mold when returning. In addition, it is possible to prevent air from being mixed into the filled material.

After filling the filling material inside the elastic filling mold as described above, the filling material inside the elastic filling mold is solidified by the solidification device. Such a solidification apparatus for a packing material includes a device for applying a heat treatment and a device for adding a freezing treatment, depending on the properties of the packing material.

Next, the solidified material inside the elastic mold is expanded from the elastic mold so that the solidified material is released from the inside of the elastic mold, and the internal material is discharged. Take sampling equipment Depending on the location, solidified molded products are taken out.

However, in this extraction device, a filled molded product in which the elastic filling mold is solidified by setting the negative side of the opening on the opposite side of the filling section of the elastic filling mold. It is possible to inflate the molded product more than that, and as a result, to remove the filled molded product, and to remove the filled product by pushing it out from the opposite opening side. You can do that too.

Therefore, the filled molded article formed in this way becomes a product with high commercial value because there are no voids inside the filled part because there is no air bubble in the filled part. It is a thing.

Best form to carry out the invention

Hereinafter, an embodiment of a machine for manufacturing a molded product using a filling device according to the present invention will be described with reference to the illustrated examples.

FIG. 1 is a block diagram showing the overall structure, and FIG. 2 is a partially omitted perspective view.

As shown in the figure, the present invention is based on a filling device 40 for filling the inside of the elastic filling type 10 with the filling material 11, and a filling device 40 for filling the filling material 11. The solidification device 60 for solidifying the filler 11 filled inside the elastically filled mold 10, and the solidification solidified inside the elastically packed mold 10

11 is formed from a withdrawing device 70 for withdrawing 1, and each of these devices is continuously provided with a transfer conveyor.

Each of the devices 40, 60, and 70 is controlled by a control device 30, while being sequentially arranged along 20.

The transfer conveyor 20 is a pulley which transmits the rotation of the motor 21 by decelerating the rotation of the motor 21 by the reduction gear 22.

Set according to control device 30 in advance according to 23 At this speed, it moves intermittently between the devices.

The transfer conveyor 20 has a large number of fixed

24 are fixed in parallel in the moving direction, and each fixed plate 24 has a size larger than the size of the filled molded product 12 as the final molded product. A fixing hole 25 is provided.

Here, the elastic filling type 10 is an open bag-shaped filling part.

13 and a fixing portion 14 formed near the opening of the filling portion 13.

The filling portion 13 is formed as a required shape of the filling molded product 12, such as a sphere, a pillar, or an animal or a specific character as appropriate. After solidification of the filling 11 filled inside 3, they will be in the shape of a sphere, a pillar, an animal or a character .

The fixing portion 14 is formed as a brim-like portion continuous with the filling portion 13, and is fixed to a number of fixing plates 24 fixed to the transfer conveyor 20. , Filled with filler 11 from the opening. Has formed.

Further, when the fixing portion 14 is inflated during the charging operation by the charging device 40 or the extracting operation by the extracting device 70-, Since only the filling portion 13 needs to be expanded, it is desirable that the filling portion 13 is formed to be slightly thicker than the filling portion 13.

This is because, when the fixing portion 14 and the filling portion 13 are formed to have the same thickness, as shown in FIG. 3, the fixing portion 14 mainly expands upon expansion as shown in FIG. As a result, the molded product 12 remains in the filling portion 13 that cannot be sufficiently expanded, and the work of extracting the molded product 12 cannot be performed. There is something.

If the fixed part 14 is formed thicker than the filling part 14, as shown in FIG. 4, the filling part 13 mainly expands as shown in FIG. As a result, the molded product 12 in the filling section 13 can be easily taken out.

FIG. 5 to FIG. 13 are drawings for explaining each of these devices individually.

5 to 9 show an embodiment of the charging device 40. This is shown.

In this case, the filling device 40 is provided with an opening of the elastic filling type 10 when the filling material 11 does not have such a large viscosity as water. The filling nozzle 41 is positioned upward, and the filling material 11 is filled directly into the filling portion 13 of the elastic filling mold 10 from the filling nozzle 41. Only the machine 42 is sufficient.

At this time, the charging nozzle 41 of the charging mechanism 42 is positioned above the elastic charging mold 10, and the filling of the elastic charging mold 10 with the filler 11 is completed. After that, the intermittent movement of the transfer conveyor 20 causes the fixed plate 24 to be formed so as to move sequentially below the filling nozzle 41 so that the filling is performed. You can do the work.

However, if the filling material 11 to be used has a high viscosity, the charging nozzle 41 of the charging mechanism 42 is positioned near the opening of the elastic filling type 10. When the filling material 11 is directly filled into the filling portion 13 of the elastic filling type 10 from the filling nozzle 41, the filling portion 13 of the elastic filling type 10 is Air has left behind and has solidified A cavity is created in the molded product 1 2.

In such a case, as shown in FIG. 5, the charging device 40 is connected to a charging device 42 and a vertical movement mechanism 43 provided above the charging device 42. It is also conceivable to form

At this time, the charging nozzle 41 of the charging mechanism 42 is firstly moved from above the transfer conveyor 20 to the elastic charging type 10 by the vertical movement mechanism 43. After lowering to the vicinity of the bottom of the head 13 and starting charging at that position, while continuing charging, the vertical movement mechanism 43 is moved according to the amount of charging. Activate and gradually charge the nozzle

4 to raise 1

Therefore, at this time, the charging speed by the charging mechanism 42 and the rising speed by the vertical movement mechanism 43 must have a certain correspondence relationship. Also, the filling speed and the vertical movement speed must be changed every time the elastic filling type 10 having a different cross-sectional shape in the height direction of the elastic filling type 10 is used. Nothing. Therefore, if the filling and the vertical movement are performed by a cam or the like, the change of the cam accompanying the change of the elastic filling type 10 is complicated. Therefore, the two variables, that is, the filling amount per unit unit and the vertical movement speed are controlled simultaneously by the program control by the controller 30. This is desirable.

In the above description, the charging mechanism 42 is moved up and down by the upper and lower mechanism 43, but the filling is performed by using the elastic filling type 10 and In order to suffice to shift the relative position with respect to the charging nozzle 41, the charging mechanism 42 is stopped and the vertical movement mechanism 4 is stopped. The elastic filling type 10 may be moved up and down according to FIG.

In addition, when the whole is placed on the line S, the elastic charging mold 10 is stopped during the charging operation by the charging device 40, and the charging operation is completed. An intermittent movement method of moving the charging device 40 later may be adopted. However, the charging device 40 is formed so as to be movable in a line, and the charging device 40 is not moved. Thus, the filling of the filler 11 may be performed.

However, when the viscosity of the packing 11 is further increased, as described above, the charging nozzle 41 is replaced with the packing nozzle 11.

New / ¾ Three

If it is only moved upward together with the filling, air bubbles such as air may be left inside the filling section 13 promptly.

In such a case, it is possible to make various efforts to pay attention to the elasticity of the elastic-filled type 10.

For example, as in the uninvented embodiment shown in FIG. 6, the charging device 40 is suctioned from the side of the anti-filling nozzle 41 with negative pressure, and the elastic charging type is used. It can also be formed such that 10 is expanded before filling begins.

More specifically, the non-filling of the elastic filling type 10 at the predetermined fixing plate 24 position and the negative pressure source on the side of the nozzle 41 are described.

5 Arrange negative pressure mechanism 52 communicating with 1

Before the filling of the packing starts, the inside of the negative pressure mechanism 52 is decompressed to expand the elastic filling mold 10.

Fill the inside of the elastically-filled mold 10 with the elastic-filled mold 10 expanded as described above.

The filling amount of this packing is the same as the appropriate filling amount when the elastic filling type 10 is a normal size. That is what you do.

Then, inside the expanded elastically charged mold 10, the packing 11 reaches only a part of the expanded elastically filled mold 10. .

After the filling of the predetermined amount of the filler 11 into the elastic charging mold 10 is completed, the pressure inside the negative pressure mechanism 52 gradually returns to the normal pressure. Adjust the negative pressure source 51 so that

Then, the size of the elastic filling mold 10 returns to the normal state, and the filling 11 fills the inside of the elastic filling mold 10 during this restoration. As a result, air bubbles can be prevented from entering the inside of the elastically-filled mold 10.

In another embodiment in which such a charging device 40 is used, the elastic charging type 10 is subjected to negative pressure by the same means as described above. In the expanded state, the filler 11 is temporarily filled with about half of the required filling amount, then the elastic filling mold 10 is returned to the normal state, and then the elastic filling mold 10 expands again. Then, fill with the filling material 11 corresponding to the remaining amount, Five

To complete the refill.

By forming in this way, it is possible to prevent air bubbles from entering the inside of the elastically filled mold 10 and to use the finer elastically filled mold 10. Can be molded

Further, for example, in a state in which the elastic filling type 10 is expanded, the primary filling device is used to once fill the filling with about half of the required filling amount, and thereafter the elastic filling type 10 is filled.

After the 10 was returned to the normal state, the inside of the elastic-filled mold 10 was slightly squeezed from both sides by a pressing device (not shown) to release the internal air. Later, it is inflated again and the secondary filling device is used to fill the remaining amount of the filling and then returned to the normal state to complete the filling. You can do that too. When using such a filling device 40, the whole unit must be intermittently moved to work sequentially with the primary filling device, pressing device, and secondary filling device. I want to

As another embodiment of the filling device 40, as shown in the embodiment shown in FIGS. 7 and 8, an elastic filling device is used. Focusing on the elasticity which is the characteristic of the mold 10, the filling unit 13 is brought into close contact with the filling nozzle 41 by the contacting device 50 in advance, and its unfolding is performed. By starting the charging of the packing 11 from this, it is possible to prevent air bubbles from being mixed.

In the embodiment shown in FIG. 7, a negative pressure mechanism 52 connected to a negative pressure source 51 is provided above the fixed member 24, and this negative pressure mechanism is operated. Thus, the charging section 13 is brought into close contact with the charging nozzle 41.

In the eighth embodiment, a high-pressure mechanism 54 arrested by a high-voltage source 53 is attached below the fixing plate 24 to operate the high-pressure mechanism. Thus, the charging section 13 is brought into close contact with the charging nozzle 41.

Regardless of which method is used, when filling 11 is started to be filled from the filling nozzle 41 into the filling section 13, the filling nozzle 4 1 At the same time, the filling part 13 with elasticity is in close contact, that is, there is no air between the filling nozzle 41 and the filling part 13 Therefore, from this state, it is necessary to start charging the packing 11 with a high pressure force higher than the pressure generated by the negative pressure source 51 or the high pressure source 53. As a result, the charging operation of the charging material 11 free of air can be performed.

Further, in the embodiment shown in FIG. 9, a flexible tube 55 is attached to the tip of the filling nozzle 41, and the flexible nozzle is attached to the filling nozzle. A pressing mechanism 56 that presses and squeezes the tubular tube 55 is provided, and at the start of filling, the elastic filling mold 10 is pressed by the pressing mechanism 56. Then, from this state, the filling material 11 is gradually expanded with the pressure slightly higher than the pressure of the pressing mechanism 56 and the elastic filling mold 10 is expanded. This is an example of the case where the replenishment is performed.

In this case, the filling material 11 is filled into the elastic filling type 10 in a state where the compressed air is almost completely eliminated. The inside of the elastic filling type 10 can be filled without bubbles.

Still further, there may be a case where it is desired to manufacture a molded article 12 using two or more kinds of materials. In such a case, for example, when a plurality of kinds of foods are piled and slaughtered in the height direction of the molded product 12, the filling device 40 as described above is used. The filler 11 composed of different materials can be manufactured by being charged a plurality of times.

However, even in the case where the molded product 12 is manufactured using two or more kinds of materials, each material is divided into an inner part and an outer peripheral surface of the molded product 12 to have a double structure. Sometimes it is not.

Specifically, for example, whiskey is filled in the inside of the chocolate, or the normal chocolate and the white chocolate are made into a double structure. This is the case.

In such a case, first, the filler 11 is attached to the inner peripheral surface of the elastic filling type 10, and the filler 11 attached to the inner peripheral surface is solidified. After forming the hollow filled molded product 12, it is further filled with another type of filler 11, and finally, the filler is placed on the fixed portion 14 side of the filled portion 13. This is to adhere and solidify 1 1. In this case, the means for adhering the packing material to the inner peripheral surface of the elastic filling mold 10 is as follows.

There are three ways

As a first means, as shown in FIG. 10, the filling nozzle 41 is formed in a rotating manner as shown in FIG. 10, and at the same time, the filling nozzle 41 is filled from the lower outer peripheral surface. Forming to blow out animals

Then, the charging nozzle 41 is inserted into the charging portion 13, and the charged material is blown out while being rotated. Ability to deposit packing on the peripheral surface

Accordingly, the solidification of the packing material after such packing of the packing material is carried out, whereby the hollow filled molded article 12 can be formed. Wear

As a second means, the filling material that has been once filled with the filling amount is filled into the inside of the elastic filling mold 10, and the mixture is solidified by the solidifying device 60.

However, since such solidification of the filler starts from the outer peripheral surface of the elastically-filled mold 10, the outer peripheral surface of the elastically-filled mold 10 is solidified before complete solidification. Become In some cases, it has not yet solidified in its center. As shown in FIG. 5, before the entire solidification is completed, and the periphery of the filling portion 13 is in a state of solidification, as shown in FIG. The suction nozzle 44 is positioned inside the part 13 to suck out the unsolidified filling material at the center of the filling device 13, and then remains on the inner peripheral surface of the elastic filling type 10. By solidifying any filler, it is possible to produce a hollow molded article 12.

Further, as a third means, the filling material, which is about half filled in the filling section 13, is blown out as shown in FIG. 12 before the filling material is solidified. The air is blown into the charging section 13 by the nozzle 45, and the packing in the charging section 13 is blown up to adhere to the inner peripheral surface of the charging section. It is a step

By solidifying in such a state, it is possible to produce a hollow molded product 12. Further, when the filling device 11 is filled with the filling material 11 as described above, the elastic filling mold 10 may be deformed depending on the filling pressure. . Moreover

11 1 Depending on the weight of the body itself, the elastically filled mold 10 may be deformed before it is solidified. In such a case, a jig (not shown) is positioned below the elastic charging mold 10 to perform a charging operation or a subsequent moving operation. Deformation can be prevented.

The embodiment shown in FIG. 13 is a bottom surface smoothing device 90.

After the filler 11 is filled in the elastic filling type 10, the smoothing device 90 is elastically charged by the air pressure from the air nozzle 91. This is for shaking 10 left and right.

By being swung right and left in this manner, the surface of the packing 11 near the opening of the elastic filling mold 10 is smoothed.

It is solidified by the solidifying device 60, and the filled molded product 12 removed by the extracting device 70 is removed. It is intended to improve the so-called "smoothness" when standing up and displaying filled molded products 12 at the time of sale.

Even when air pressure is not used, for example, a contact piece is provided to make the elastic-type filling mold 10 collide during the movement after the filling by the filling device 40, for example. It may be formed so as to swing right and left by making contact with the contact piece.

The solidifying device 60 is a device for solidifying the packing 11 inside the elastic filling mold 10.

This device is formed by a heating mechanism, a cooling mechanism, a combination of these mechanisms, or another mechanism.

The specific configuration of the solidifying device 60 is determined by the material of the packing 11.

For example, oils, fats, butters, margarines, chocolates, cheeses, and zeolites that solidify when the filler 11 is cooled. In the case of a tree, an ice cream, water, or the like, the solidifying device 60 is placed as a cooling device. Conversely, the packing 11 is a protein solution which is solidified by heating, kneaded kamaboko, gummi, eraser, etc. In this case, the solidifying device 60 is arranged as a heating device.

Further, when the filling 11 is a food, it may be necessary to solidify the filling 11 and cook it. In such a case, the solidifying device 60 can be used with a cooking device attached thereto.

Since the unfilled invention uses the elastic filling type 10 as the filling type, the volume of the filling 11 when the solidification 11 is solidified by the solidification device 60 is increased. Even if the value increases or decreases, the elastically filled mold 10 is not damaged. In the case of a packed type consisting of a projectile, for example, when water is solidified as the packing 11, the volume increases, so the internal pressure due to the increase in the volume increases. In some cases, the filled mold may burst, but if not invented, the elastic filled mold

Since 10 increases as the volume increases, no accidents such as rupture occur. FIGS. 14 and 15 show a removal device 70 for removing the solidified molded product 12 from the inside of the filled portion 13 of the elastically filled mold 10. It is a thing.

In such a removal device 70, the elastically filled mold 10 is pressed by pressing the filled molded product 12 from the opening side of the elastically filled mold 10, whereby the elastically filled mold 10 becomes elastic. Since the expansion is carried out by the method, the molded product 1 2 can be extruded.

Further, after the opening is expanded by an external force in advance, the molded product 12 can be pushed out from the side opposite to the opening.

However, whichever method is used, the opposite opening side of the filled molded product 12 may be deformed by the pushing force.

Thus, as a specific example of a method of not applying an external force to only a part of the molded product 12 as described above, there is a drawing device 70 as follows.

Such a removal device 70 is configured such that the filling portion 13 below the fixing plate 24 of the transfer conveyor 20 is turned upside down by the pulley 23 and turned upward. Position

Paper At the same time, by inflating the filling section 13, the inside filled product 12 is extracted and the removal unit 70 is removed below the removal conveyor 7 1. Is to be dropped. The removal of the filled molded product 12 can be performed when the filled portion 13 is in a horizontal state.

More specifically, the rotating shaft 72 rotated by the motor 21, the negative pressure cam 73 fixed to the rotating shaft 72, and the rotation of the negative pressure cam 73 The transmission rod 74 is oscillated by this, and the negative pressure body 75 supported at the tip of the transmission rod 74 is formed.

The rotating shaft 72 is rotated by the same motor 21 for moving the transfer conveyor 20 so as to synchronize with other devices. It is something.

The negative pressure cam 73 is formed as a front cam fixed to the rotating shaft 72.

The negative pressure body 75 is connected to a negative pressure source 76 to make the negative pressure chamber 77 inside the negative pressure body 75 a negative pressure state. The negative pressure source 76 is formed of a vacuum pump, a valve, a pressure gauge, and the like, although detailed illustration is omitted. '

The negative pressure chamber 77 is formed to have a size to cover the filling portion 13 in which the filling molded product 12 is placed, and a cushion 78 is fixed to an inner upper surface.

Such an operation of the extracting device 70 is performed after the filling material 11 filled in the filling portion 13 is solidified by the solidifying device 60, and then the pulley 23. And the simple transfer by the transfer conveyer 20 so that the filling portion 13 in which the filled product 12 is solidified is located above. I will do it.

When the negative pressure chamber 77 covers the upper part of the filling section 13 this year and the inside of the food pressure chamber 77 is set in a negative pressure state by the negative pressure source 76, the elastic body is formed. The formed elastic filling mold 10 expands so as to be in close contact with the inner wall of the negative pressure chamber 77. At this time, not only the filling portion 13 of the elastic filling type 10 but also the fixing portion 14 are deformed as closely as possible to the inner wall of the negative pressure chamber 77, so that Opening corresponding to fixing hole 25 of fixing plate 24 Is formed at the bottom.

However, in the embodiment, the fixing part 14 is filled with

Since it is formed thicker than 13, the filling part 13 expands greatly when it expands, and the fixed part 14 fills the filling part.

Since it expands so as to deform to the 13 side (see Fig. 4), it is easy to remove the filled molded product 12.

As a result, the molded product 1 2 separates from the elastic molded mold 10 and drops downward from the fixing hole 25 of the fixing plate 24 larger than the molded product 12. That will be.

The molded product 12 that has fallen down like this is placed on the unloading conveyor 71 located at the lower part of the extraction device 70. It is transferred to a predetermined position.

When a negative pressure state is formed in this way, the filling portion 13 extends in a direction in which the elastic filling mold 10 easily expands, that is, in the illustrated example, upwards. There is a possibility that the shape may be broken by abutting against the inner upper surface of 77.However, in the example shown, the cushion 78 is fixed to the upper surface of the negative pressure chamber 77. There is no need to worry about losing shape.

Further, in the illustrated example, the rotating cam 72 is also provided with the proposed cam 79.

The guide cam 79 moves up and down the guide 侓 80 for taking out the filled molded product 12 dropped from the filling section 13 and guiding it to the conveyor 71. It is to make it happen.

Although the negative pressure chamber 77 is formed in a closed cylindrical shape in the illustrated example, a filled molded product 12 released from the elastically filled mold 10 is provided inside the negative pressure chamber 77. Although it is not shown in the figure from the point of preventing it from being caught on the opening, the opening side is formed to be divergent, or a divergent tail is formed at the opening. It is desirable to attach a pad. However, the shape of the filled product 12 is complicated, or the filled product 12 is an elastic filling mold 10. FIG. 15 shows a molded product 12 which is not easily released by the extracting device 70 as described above due to the adhesive force between the molded product 12 and the molded product 12. Thus, the vertical moving device 81 and the negative pressure suction device 82 are attached to the guide body 80. In addition, it is possible to forcibly release the charged molded product 12 from the elastically charged mold 10 by the negative pressure adsorption device 82.

More specifically, first, the negative pressure suction device 82 of the guide body 80 is solidified inside the elastic filling mold 10 by the vertical movement device 81 into a filled product 12. It is made to approach and then negative pressure adsorption.

Next, the inside of the negative pressure chamber 77 is depressurized by the negative pressure source 76, and the elastic filling type 10 is expanded inside the negative pressure chamber 77.

At this time, since the molded product 12 remains adsorbed on the negative pressure adsorption device 81, the charged molded product 12 is elasticized while adsorbed on the negative pressure adsorption device 81. Sex filling type

Only 10 expands, and the filled product 12 is detached from the elastic filling mold 10 at the position where it is adsorbed by the negative pressure adsorption device 81.

If it is difficult to remove the device by such means, the negative pressure suction device 82 of the guide body 80 is moved by the vertical movement device 82 shown in FIG. Elastic filling type

1 0 Close to the internal molded product 1 2 After that, move it slightly upward.

As a result, air enters between the vicinity of the opening of the filling portion 13 of the elastic filling type 10 and the filling molded product 12. Therefore, when the elastic filling mold 10 is then expanded inside the negative pressure chamber 77, the molded article 12 and the elastic filling mold 10 are expanded from the portion where the air enters. As a result, separation from the elastically-molded mold 10 of the molded article 12 can be performed more reliably.

As a result of various experiments, when producing ice as a filled molded product 12, the filling part 13 of the elastic filling mold 10 is 0.5-0.8am, and the fixed part is 0.8-l. When formed with a rigid latex having a thickness of about lmm and a negative pressure of about 5QQnaHg, it was confirmed that the mold was completely released at 0.5 ~: Isec and dropped.

The filled product 12 manufactured in this way has a full shape determined by the filled portion 13 of the elastically filled plastic 10. By making various kinds of products, it is possible to make a filled product 12 of any shape. Also, unlike the solid body, the elastically-filled mold 10 can be mass-produced at low cost, so that the cost of the molded article 12 itself can be reduced. However, unlike the split type, since there is no split line, the finished filled product 12 becomes a natural shape in the form of S and has high commercial value. Further, since there is no need to divide in multiple directions, the manufacturing process can be simplified.

Further, since the elastic filling type 10 was used as the filling type, even if the volume of the filling 11 was changed during the solidification process by the solidification device 60, Since the elastic filling type 10 can sufficiently cope with the expansion and contraction, the elastic filling type 10 is not damaged.

Further, since the extraction device 70 is formed so as to extract using a negative pressure, the shape of the filled molded product 12 is not damaged during the extraction process.

In the above description, the elastically-filled type 10 is made of any material as long as it is stretched when it is stretched, such as soft rubber or soft plastic. It is a thing. Industrial availability

As described above, the present invention is based on the fact that the elastic filling type having the filling portion of the opening bag is used instead of the filling type. In addition to reducing the cost of manufacturing the filled mold itself and preventing damage to the filled mold, it is also possible to manufacture unfilled molded products. The packing material can be filled inside the elastic packing mold so that bubbles are not generated without being influenced by the viscosity of the packing material. There is
