Description

Detailed Description of the Invention [Industrial Application Field] The present invention is directed to a filling molded product manufacturing machine, more specifically, to an elastic filling mold having an open bag-like filling part, in which a non-solid filler such as water or The present invention relates to a filling molded product manufacturing machine for filling food products such as dough chocolate, kamaboko, rummy, etc., stationery such as erasers, etc., and solidifying and molding the filled products.

[Prior Art] Conventionally, filled molded products have been manufactured using filling molds, regardless of whether they are food products or other products.

Such conventional filling molds are formed from a plurality of divided molds made of rigid bodies according to the shape of the filled molded product.

In the conventional filling mold using split molds, fillers are filled into the split molds, the filler is solidified inside the split molds, and then taken out by dividing the split molds. Ta.

[Problems to be solved by the invention] However, since filled molded products manufactured using such conventional filling molds are manufactured using split molds, dividing lines of the split molds inevitably appear, making it difficult to manufacture. This would reduce the commercial value of the filled and molded products.

Furthermore, in order to manufacture a filled molded product with a particularly complicated shape, a large number of divided molds are required, which also complicates the manufacturing process.

Furthermore, since the split mold itself is formed of a rigid body, a large amount of cost is required to manufacture the split mold itself, which has a large impact on the product cost. Particularly in the case of manufacturing a wide variety of products in small quantities, the cost of dividing the molded product as a whole is so large that it is almost impossible to manufacture the product.

Furthermore, when using a conventional rigid split-fill mold, if the volume of the filler increases or decreases during solidification, the split-fill mold may be damaged by pressurization or depressurization during the solidification process.

Therefore, the present invention uses an elastic filling mold having an open bag-like filling part as the filling mold, thereby making it possible to manufacture a filling molded product without a dividing line, reducing the manufacturing cost of the filling mold itself, and reducing the filling cost. The purpose of the present invention is to provide a filled and molded product manufacturing machine that prevents damage to the mold, significantly streamlines the manufacturing process, and allows smooth removal of solidified filling from inside the mold. .

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a filling device for a non-solid filler in an elastic filling mold in which an open bag-like filling portion is formed, and a device for filling a non-solid filler in an elastic filling mold. It consists of a device for solidifying the filling inside the elastic filling mold, and a sampling device for taking out the solidified filling from inside the filling section of the elastic filling mold. It is characterized in that it is formed by providing a negative positive chamber in which the pressure is in a negative pressure state.

[Function] In the uninvented filling molded product manufacturing machine, first, a filling device fills an elastic filling mold with a filling material.

This elastic filling mold uses an elastic material because it is necessary to take out the solidified filling by expanding the whole in an extraction device.

After filling the inside of the elastic filling mold with the filler in this manner, the filling inside the elastic filling mold is solidified by a solidifying device. Devices for solidifying such fillers include devices that apply heat treatment, devices that apply freezing treatment, etc., depending on the properties of the filler.

Next, the elastic filling mold is expanded so that the solidified filling inside the elastic filling mold is released from the inside of the elastic filling mold, and the solidified filling is removed by an extraction device that extracts the filling inside the elastic filling mold.
It manufactures molded products.

However, regarding this extraction device, in the present invention, the elastic filling mold is inflated by creating a negative pressure state on the side opposite to the opening of the filling portion of the elastic filling mold, and as a result, the filled molded product inside is extracted.

[Example] Embodiments of the present invention will be described below according to illustrated examples.

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

As shown in the figure, the present invention includes a filling device 40 for filling the inside of the elastic filling mold 10 with the filling material 11, and a filling device 40 that fills the inside of the elastic filling mold 1 with the filling material 1.
The solidifying device 60 solidifies the filling material 11, and the extracting device 2170 uses negative pressure to remove the solidified filling material 11 inside the elastic filling mold 10. They are arranged in sequence and can be freely controlled by the control device 30.

Further, the transfer conveyor 20 controls the rotation of the motor 21 by using a reducer 2.
The pulley 23, which is transmitted at a reduced speed according to 2, moves between each device at a speed preset by the control device 30.

In addition, a large number of fixed plates 24 are fixed to the transfer conveyor 20 in parallel in the moving direction, and each fixed plate 24 of the bracket
A fixing hole 25 larger than the size of the filled molded product 12 as the final molded product is bored in the hole.

Here, the elastic filling mold 10 is formed of an open bag-shaped filling part 13 and a fixing part 14 formed near the opening of the filling part 13.

The filling part 13 is formed in the shape of a sphere, a column, an animal or a specific character, etc., and after solidifying the filling material 11 filled inside the filling part 13, the filling part 13 is shaped like a sphere, column, animal, or character. It is designed to have a - shape.

Further, the fixing part 14 is formed as a flange part of approximately the same thickness that is continuous with the filling part 13, and is fixed to a large number of fixing plates 24 fixed to the transfer conveyor 20, and allows the filling material 11 to be inside the filling part 13 from the opening. It is formed so that it can be filled freely.

FIGS. 3 to 8 are drawings for explaining each of these devices individually.

3 to 5 show the filling device 40. FIG.

Here, when the filling material 11 does not have a very high viscosity, the filling device 40 positions the filling nozzle 41 above the opening of the elastic filling mold 10, and the filling nozzle 4
1 directly into the filling part 13 of the elastic filling mold 10.
Only the filling mechanism 42 that fills the liquid is sufficient.

At this time, the filling nozzle 41 of the filling mechanism 42 is positioned above the elastic filling mold 10, and after filling the elastic filling mold 10 with the filling material 11 is completed, the movement of the transfer conveyor 20 sequentially moves the fixing plate 24 By forming the nozzle so that it moves below the filling nozzle 41, the filling operation can be performed.

As the filler 11 to be manufactured in this way, water and the like can be used as the filler 11 with low viscosity when manufacturing ice or the like of an appropriate shape.

Note that when the viscosity of the filling material 11 is high, the filling nozzle 41 of the filling mechanism 42 is positioned near the opening of the elastic filling mold 10, and the filling nozzle 41 directly supplies the elastic filling mold 10.
When the filling part 13 is filled with the filling material 11, air remains inside the filling part 13 of the elastic filling mold 10, and a cavity is created in the solidified filled molded product 12.

In such a case, as shown in FIG.
It may be formed by a filling mechanism 42 and a vertical movement mechanism 43 provided above the filling mechanism 42.

At this time, the filling nozzle 41 of the filling mechanism 42 is first lowered from above the transfer conveyor 20 to the vicinity of the bottom of the filling part 13 of the elastic filling mold 10 by the vertical movement a mechanism 43, and after filling the filling part 13 of the elastic filling mold 10 slightly at that point, the filling nozzle 41 is Vertical movement mechanism 43 according to the amount
The filling nozzle 41 is gradually raised.

Therefore, at this time, the filling speed by the filling mechanism 42 and the rising speed by the vertical movement mechanism 43 must have a certain correspondence relationship, and the elastic filling molds 10 have different cross-sectional shapes in the height direction. Each time it is used, the filling speed and vertical movement speed must be changed. Therefore, filling and vertical movement are performed by a cam etc.
Since changing the cam due to changing the elastic filling mold 10 is complicated,
It is desirable to simultaneously control the two variables, the filling amount per unit time and the vertical movement speed, by program control.

Furthermore, in the above explanation, the filling mechanism 42 is moved up and down by the vertical movement mechanism 43, but in contrast, the filling mechanism 42 is moved up and down by the vertical movement mechanism 43.
may be stopped and the elastic filling mold 10 may be moved up and down by the up and down movement mechanism 43.

In addition, if the entire filling device is placed on a line, the filling device fi
During the filling operation using the filling device 40, the elastic filling mold 10 may be stopped, but the filling device 40 itself is formed to be movable along the line, and the filling device 40 is filled with the filling material 11 while moving. You can do it as well.

Further, when the viscosity of the filler 11 is even higher, if the filling nozzle 41 is simply moved upward together with the filler 11 as described above, bubbles such as air will still remain inside the filling part 13. Sometimes.

In such a case, as shown in Figures 4 and 5,
Focusing on the elasticity of the elastic filling mold 10, the filling part 13 is brought into close contact with the filling nozzle 41 using the IE mounting neck 50 in advance, and filling of the filling material 11 is started from that state, thereby preventing air bubbles from being mixed in. can do.

In the embodiment shown in FIG. 4, a negative pressure source 5 is provided above the fixed plate 24.
A negative pressure mechanism 52 connected to the filling part 13 is attached to the filling nozzle 41 by operating this negative pressure mechanism.
It is closely connected to the

Further, in the embodiment shown in FIG. 5, a high pressure mechanism 54 connected to a high pressure source 53 is attached below the fixed plate 24, and this high pressure
By operating the mechanism, the filling portion 13 is brought into close contact with the filling nozzle 41.

No matter which means is used, when starting to fill the filling part 13 with the filling material 11 from the filling nozzle 41,
Since the filling part 13 having elasticity is in close contact with the filling nozzle 41, that is, there is no air between the filling nozzle 41 and the filling part 13, the pressure generated by the negative pressure source 51 or the high pressure source 53 is generated from this state. Filling 11 at a pressure higher than the pressure
By starting the filling of the filler 11, it is possible to perform the filling operation of the filler 11 without mixing air.

Furthermore, when filling the filling material 11 with such a filling device 40, the elastic filling mold 10 may be deformed depending on the filling pressure. In such a case, deformation can be prevented by positioning a jig (not shown) below the elastic filling mold 10 and performing the filling operation.

The solidification bag 60 is a device for solidifying the filling material 11 inside the elastic filling mold 10.

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

The specific configuration of the solidification bag 60 is determined by the material of the filling material 11.

For example, if the filler 11 is water or the like that solidifies by cooling, the solidifying device 60 is arranged as a cooling device.

Conversely, if the filling material 11 is a paste-like kamaboko, tsumire, eraser, etc. that can be solidified by heating, the solidification device 60 is used as a heating device.
! i, it is placed.

Furthermore, when the filling 11 is a food product, the filling 1
1 may need to be cooked as well as solidified. In such a case, the solidification device 60 may be used with a cooking device attached thereto.

In addition, in the present invention, since the elastic filling mold 10 is used as the filling mold, when the filling material 11 is solidified by the solidifying device 60,
Even if the volume of the filling 11 increases or decreases, the elastic filling filO will not be damaged. For example, in the case of a filling mold made of a rigid body, solidifying water as the filling 11 increases the body a. Although the filling mold may burst due to internal pressure due to volume increase, in the present invention, the elastic filling mold 10
Because it expands as the volume increases, accidents such as rupture do not occur.

6 and 7 show a filling part 13 of 1 elastic light Mi4 type IO.
This figure shows a extraction device 70 for removing the solidified filled molded product 12 from inside.

This extraction device 70 is connected to the fixed plate 24 of the transfer conveyor 20.
The filling part 13 located below is reversed by the pulley 23 and moved upward, and by inflating the filling part 13, the filled molded product 12 inside falls onto the take-out conveyor 71 below the extracting device 7o. It is something that makes you

Specifically, a rotating shaft 72 rotated by the motor 21, a negative pressure cam 73 fixed to the rotating shaft 72, a transmission rod 74 that swings due to the rotation of the negative pressure cam 73, and a tip of the transmission rod 74. The negative pressure body 75 is pivotally supported by the negative pressure body 75.

The rotating shaft 72 is rotated by the same motor 21 as the motor 21 for moving the transfer conveyor 20 in synchronization with other devices.

Further, 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 the negative pressure rA76, and brings the negative pressure chamber 77 inside the negative pressure body 75 into a negative pressure state.

Although detailed illustration is omitted, the negative pressure source 76 includes a vacuum valve,
It consists of a rupture valve, compressor, etc.

The negative pressure chamber 77 is formed in a size that covers the filling part 13 containing the filled molded product 12, and has a cushion 7 on the upper surface of the inside.
8 is fixed.

Such an operation of the extraction device 70 is such that the filling 11 filled inside the filling part 13 is solidified by the solidification device l! After being solidified by 160, the filled molded product 12 is turned over by a pulley 23 and moved by a transfer conveyor 20 so that the filling part 13, in which the filled molded product 12 is solidified inside, is positioned above.

At this time, the negative pressure chamber 77 covers the upper part of this filling part 13,
When the inside of the negative pressure chamber 77 is brought into a negative pressure state by the negative pressure source 76, the elastic filling mold 10 formed of an elastic body fills the negative pressure chamber 7.
It will come into close contact with the inner wall of No.7. At this time, not only the filling part 13 of the elastic filling mold 10 but also the fixing part 14 are brought into close contact with the inside of the negative pressure chamber 77 as much as possible, so that an opening corresponding to the fixing hole 25 of the fixing plate 24 is formed in the lower part. That will happen.

Then, the filled molded product 12 separates from the elastic filling mold 10, and the fixing hole 2 of the fixing plate 24, which is larger than the filled molded product 12, moves away from the elastic filling mold 10.
It will fall downward from 5.

Further, the vehicle load 12 that has fallen downward in this way is placed on a take-out conveyor 71 located at the bottom of the take-out device W170 and transported to a predetermined position.

When a negative pressure state is created in this way, the filling part 13 will extend in the direction in which the elastic filling mold 10 tends to expand, that is, upward in the illustrated example, and there is a risk that the filling part 13 will collide with the internal upper surface of the negative pressure chamber 77 and break its shape. However, in the illustrated example, the cushion 78 is fixed to the upper surface of the inside of the negative pressure chamber 77, so there is no fear of the mold being worn out.

Further, in the illustrated example, a guide cam 79 is also fixed to the rotating shaft 72.

The guide cam 79 is for vertically moving a guide body 80 for guiding the filled molded product 12 that has fallen from the filling section 13 to the conveyor 71.

However, regarding the filled molded product 12 that cannot be easily released from the mold by the sampling device ff170, it is also possible to forcibly release the filled molded product 12 by controlling the negative pressure of this guide body 80 as well.

Although this negative pressure chamber 77 is formed into a cylindrical shape with a lid in the illustrated example, the filled molded product 12 released from the elastic filling mold 10
Although not shown in the drawings, in order to prevent the inside of the negative pressure chamber 77 from getting caught, the whole part may be formed to widen toward the end, or
Alternatively, it is desirable to add a taper that widens toward the bottom.

As a result of various experiments, when manufacturing ice as the filled molded product 12, the elastic filling mold 10 is made of a rigid latex of 0.8 to 0.8-intestine, and the negative pressure is approximately 500 mHg.
It was confirmed that the mold was completely released and fell in 0.5 to 1 sec.

The filled molded product 12 manufactured in this way is as follows.

Since the overall shape is determined by the shape of the filling part 13 of the elastic filling mold 10, it is possible to make a filled molded product 12 of any shape by adjusting the amount of elastic filling.

In addition, unlike rigid filling molds, the elastic filling mold 10 can be mass-produced at low cost, so not only can the cost of the filling molded product itself be reduced; Unlike ffi, there is no dividing line, so the completed filled molded product 12 has an extremely natural shape and has high commercial value. Furthermore, there is no need to divide it into multiple directions.

The manufacturing process can also be simplified.

Furthermore, since the elastic filling mold 10 is used as the filling mold, even if the volume of the filling material 11 changes during the solidification process using the solidification device g160, it can be sufficiently accommodated by the expansion and contraction of the elastic filling mold 10. No damage of 10.

Furthermore, since the extracting device 70 is formed to extract using negative pressure, there is no damage to the shape of the filled molded product 12 during the extracting process.

In the above description, the elastic filling mold 10 may be made of any material as long as it stretches when pulled, such as soft rubber or soft plastic.

[Effects of the Invention] As explained above, the present invention provides the following effects as a filling type.
By using an elastic filling mold consisting of a pouch-shaped filling part and a fixing part formed near the opening of this filling part, it is possible to manufacture a filled molded product without a dividing line, and
This reduces the manufacturing cost of the filling mold itself, prevents damage to the filling mold, and at the same time greatly simplifies the manufacturing process.Furthermore, the solidified filling material can be smoothly removed from the inside of the filling mold.
