Layer A and B materials remain nearby. In addition, it is possible to prevent various problems that may occur because the A-layer material and the B-layer material remain near the end of the discharge nozzle.

In addition, by controlling the ejection mechanism portion 10a, the operations of the forming mechanism portion 10b, the film feeding mechanism 10c, or the sealing mechanism portion 10d are controlled according to the discharge condition of the multilayer object, and the sheath S is formed by the film F. The multilayer is packaged to make a multilayer product P.

"About the manufacturing method of multilayer product P"

Hereinafter, referring to the flowchart shown in FIG. 5 and the time chart shown in FIG. 6, The manufacturing method of the multilayer product P which is executed under the operation control of the control unit 10e will be described in detail.

(step 1)

In step 1, it is confirmed whether the operation signal of the multilayer product manufacturing apparatus 10 is ON. When it is confirmed that the operation signal is on, the control flow proceeds to step 2.

(Step 2)

In step 2, the operation of forming the sheath S by the thin film F is started under the control of the control unit 10e. Then, the control flow goes to step 3.

(Step 3)

In step 3, supply of the outer layer material by the outer layer material supply device 32 is started (see FIG. 6). Accordingly, the discharge nozzle 42 provided in the discharge unit 40 discharges the outer layer material downward from the gap formed between the inner layer material discharge tube 52 and the outer layer material discharge tube 54 (the outer layer material discharge start step).

(Step 4)

In step 4, it is confirmed whether or not a predetermined time t3 has elapsed since the outer layer material started to be discharged in step 3 (see FIG. 6). Here, the predetermined time t3 is based on various conditions such as the viscosity of the outer layer material and the inner layer material, the discharge speed, the shape of the discharge nozzle 42 and the thickness of the outer layer material constituting the multilayer product. According to the conditions, the outer layer material and the inner layer material can be simultaneously ejected without setting a predetermined time t3 (t3 = 0). When it is confirmed in step 4 that the predetermined time t3 has elapsed, the control flow proceeds to step 5 (inner layer material ejection start step).

(Step 5)

In step 5, while continuing to start the discharge of the outer layer material in the above step 3, the operation of discharging the inner layer material from the inner layer material discharge tube 52 of the discharge nozzle 42 to the lower side is started. That is, from the time when the predetermined time t3 has elapsed after the outer layer material started to be ejected in step 3, the outer layer material is also ejected simultaneously with the inner layer material.

(Step 6)

In step 6, it is confirmed whether or not a predetermined time t4 has elapsed since the inner layer material started to be discharged in step 5 (see FIG. 6). The predetermined time t4 is appropriately adjusted in accordance with the size (length) of the manufactured multilayer. When it is confirmed in step 6 that the predetermined time t4 has elapsed, the control flow proceeds to step 7.

(Step 7)

In step 7, the rotation direction of the rotor 102 of the inner-layer material supply device 22 is switched to a direction opposite to that when the inner-layer material is ejected within a predetermined time t5. That is, as shown in FIG. 6, the output as a control signal for the rotor 102 is inverted from that before it is confirmed that the predetermined time t4 has passed in step 6. Control signal. Thereby, the inner-layer material supply device 22 performs an operation of sucking back the inner-layer material supplied to the discharge nozzle 42 during the period up to step 6. When the prescribed time t5 has elapsed after the suction of the inner layer material is started, the control flow proceeds to step 8.

(Step 8)

In step 8, the rotation of the rotor 102 which moves toward the suction direction of the inner layer material is stopped (steps 7 to 8: step of stopping the discharge of the inner layer material). Then, the control flow goes to step 9.

(Step 9)

In step 9, it is confirmed whether or not a predetermined time t1 has elapsed after starting the discharge of the outer layer material (see FIG. 6). Here, although the ejection of the inner layer material has been completed up to step 8 described above, the ejection of the outer layer material has not yet ended but continues. Then, when it is confirmed that the predetermined time t1 has elapsed after the outer layer material is started to be discharged, the control flow proceeds to step 10.

(Step 10)

In step 10, the rotation direction of the rotor 202 provided in the outer layer material supply device 32 is switched to a direction opposite to that when the outer layer material is ejected within a predetermined time t2. That is, the outer-layer material supply device 32 performs an operation of sucking back the outer-layer material to the discharge nozzle 42 during the period up to the previous step. As shown in FIG. 6, the prescribed time t2 required for the reabsorption of the outer layer material is much shorter than the prescribed time t1. When the back suction of the outer material starts When the predetermined time t2 has elapsed, the control flow proceeds to step 11.

(Step 11)

In step 11, the supply of the outer layer material is stopped by switching the rotor 202 of the outer layer material supply device 32 to the rotation stop state (steps 10 to 11: the outer layer material discharge stop step). As a result, a series of ejection operations of the multilayer object performed from step 3 to step 11 is completed. Then, the control flow goes to step 12.

(Step 12)

In step 12, the film feed mechanism 10c is operated to carry the processing of transporting the film F (skin S) of the length required to form the seal portion 84 toward the downstream side. That is, if there is a multilayered object in the formation portion of the seal portion 84, the seal portion 84 cannot be formed smoothly, which may result in poor sealing. Therefore, the operation of conveying the film F of the length required to form the seal portion 84 toward the downstream side while stopping the discharge of the multilayered object is performed. As a result, a series of operations shown in the flowchart of FIG. 5 and the time chart of FIG. 6 ends.

As described above, according to the multilayer product manufacturing apparatus 10, the multilayer S can be covered with the sheath S, and the film F (skin S) can be sealed by the sealing mechanism portion 10d, and the envelope S is formed by the formed mechanism portion 10b. The cylindrical film F is formed. This makes it possible to provide a multilayer product P that is easy to use or store, and has good hygiene. In addition, as described above, the multiple layers ejected from the ejection mechanism section 10a are covered with the sheath S In the case of an object, even if the multi-layer object is made of a soft material, it can be easily transported without breaking its shape. Further, since it can be provided in a state where the multilayered object is covered with the sheath S, it is possible to easily perform treatment such as heating or cooling. Therefore, according to the multilayer product manufacturing apparatus 10 of this embodiment, it is possible to increase the added value of a multilayer object and diversify its use.

In addition, in the present embodiment, as the multilayer product manufacturing apparatus 10, a structure for manufacturing a multilayered structure for enclosing the outer layer of the inner layer material constituting the center with a single outer layer material is exemplified. However, the present invention is not Limited to this, the multi-layer product manufacturing apparatus 10 may also be formed into a structure for manufacturing a multi-layer object having a multi-layer structure. For example, in the case of manufacturing a multilayer product P having a three-layer structure including a center layer P4, an intermediate layer P5, and an outer layer P6 from the center side to the outside, the multilayer product manufacturing apparatus 10 is formed as follows, as shown in FIG. 7, The nozzle structure 44 (also referred to as "first nozzle structure 44") of the first discharge area 42a and the second discharge area 42b is formed by using the inner layer material discharge tube 52 and the outer layer material discharge tube 54 in the same manner as the above-mentioned discharge nozzle 42. In addition, another ejection tube (third ejection tube 56) that surrounds the outer material ejection tube 54 is provided to form a third ejection area 42c between the outer material ejection tube 54 and the third ejection tube 56. Thus, in addition to the first nozzle structure 44, a second nozzle structure 46 composed of an outer layer material discharge cylinder 54 and a third discharge cylinder 56 is formed. Thus, by forming the nozzle structure into a multilayer structure, it is possible to further multi-layer the discharged matter formed in the discharge mechanism section 10 a.

As described above, according to the multilayer product manufacturing apparatus 10, the outer layer material may be made of a material having the same viscosity as the inner layer material, or a material having a lower viscosity than the inner layer material. Therefore, according to the multi-layered product manufacturing apparatus 10, it is possible to manufacture a multi-layered product P which cannot be manufactured by a prior art stuffing product manufacturing apparatus or the like and whose outer layer material is made of a material having a lower viscosity than the inner layer material.

As described above, in the multilayer product manufacturing apparatus 10, during the manufacturing process of the multilayer product P, the following supply control is performed, that is, when the multilayer object discharged from the discharge mechanism portion 10a reaches the position where the sealing portion 84 should be formed in the cylindrical film F The supply of the inner layer material and the outer layer material was stopped at the previous moment. By performing such control, it is possible to reduce the possibility that a multi-layered object adheres to the position where the seal portion 84 should be formed on the film F, and to suppress the occurrence of a failure such that the seal portion 84 cannot be formed smoothly.

In the multilayer product manufacturing apparatus 10, the inner layer material supply device 22 and the outer layer material supply device 32 are each equipped with uniaxial eccentric screw pump mechanisms 100 and 200. Therefore, it is possible to control the supply state of the inner layer material and the outer layer material with high accuracy, so that a proper amount of the inner layer material and the outer layer material can be ejected at an appropriate time during the manufacturing process of the multilayer product. Therefore, the multilayer product manufacturing apparatus 10 can further improve the manufacturing quality of the multilayer product.

In addition, the uniaxial eccentric screw pump mechanisms 100 and 200 constituting the inner layer material supply device 22 and the outer layer material supply device 32 can appropriately switch the flow direction of the inner layer material and the outer layer material by adjusting the rotation directions of the rotors 102 and 202. . So even the inner and outer materials A low-viscosity material is used as the material, and by rotating the rotors 102 and 202 in the reverse direction when the supply of each material is stopped, unexpected dripping can also be prevented, and the quality of multilayer products can be reduced due to dripping.

In addition, the structure of the uniaxial eccentric screw pump mechanisms 100 and 200 constituting the inner layer material supply device 22 and the outer layer material supply device 32 is extremely simple. Accordingly, it is possible to suppress the manufacturing cost of the multilayer product manufacturing apparatus 10 and improve the maintenance characteristics.

In the multilayer product manufacturing apparatus 10, since the inner layer material supply device 22 and the outer layer material supply device 32 are provided with uniaxial eccentric screw pump mechanisms 100 and 200, it is possible to accurately control the start and end of the discharge of the inner layer material and the outer layer material. Therefore, as described above, when the predetermined time t3 elapses after the outer layer material supply device 32 starts to supply the outer layer material, the inner layer material supply device 22 starts to supply the inner layer material, and the outer layer material supply device 32. The supply of the inner layer material by the inner layer material supply device 22 is stopped at a predetermined time t1 before the supply of the outer layer material is stopped until the supply is stopped. In this case, a high-quality multilayer product can be stably manufactured.

In addition, as the manufacturing method of the multilayer product P of the above embodiment, the outer layer material ejection start step (step 3), the inner layer material ejection start step (step 5), and the inner layer are sequentially performed as shown in the control flow in FIG. 5 as an example. Examples of the respective steps of the layer material ejection stop step (step 7 to step 8) and the outer layer material ejection stop step (step 10 to step 11). However, other steps may be added in addition to these steps. Specifically, after the outer layer material ejection start step and the inner layer Prior to the material ejection start step, a step of sucking the outer layer material by rotating the rotor 102 of the inner layer material supply device 22 in a direction opposite to that when the inner layer material is ejected is provided.

By providing the outer layer material suction step, after the outer layer material discharge initiation step, the outer layer material discharged from the outer layer material discharge tube 54 of the discharge nozzle 42 and adhered to the front end portion thereof is attracted to the inner layer material discharge tube 52. Therefore, before the inner layer material discharge start step, the front end portion of the inner layer material discharge cylinder 52 is filled with a small amount of outer layer material. In this state, when the manufacturing step is shifted from the outer layer material suction step to the inner layer material discharge start step, the inner layer material is discharged after the outer layer material filled in the front end portion of the inner layer material discharge cylinder 52 is discharged. Therefore, the multilayer product P thus manufactured has a structure in which the lower portion of the inner layer material is reinforced by ejecting the outer layer material from the inner layer material ejection cylinder 52 immediately after the start step of the inner layer material discharge step. This can suppress manufacturing defects such as leakage of the inner layer material from the bottom side of the multilayer product P due to the influence of the weight of the inner layer material and the like, thereby contributing to improvement in yield.

The multilayer product manufacturing apparatus 10 described above can manufacture a multilayer product P that uses a sheath F formed by a film F to cover a multilayer. However, the multilayer product manufacturing apparatus 10 may be configured to perform some post-processing such as heat treatment or sterilization of the multilayer product P. . Specifically, as shown by a two-dot chain line in FIG. 1, the multilayer product manufacturing apparatus 10 may be provided with a heat treatment device 90. The heat treatment device 90 may further perform a multilayer product P that uses a sheath S to cover a multilayer object. Either or both of the heat treatment and the cooling treatment are performed. With such a structure, Performing post-treatments such as heat treatment such as heat treatment or cooling treatment on the multilayered object covered by the sheath S can further increase the added value of the multilayered product P.

Specifically, by performing a heat treatment, a product that is completed by heating a multilayered object covered with the sheath S can be produced, and effects such as a sterilization effect can also be expected. In addition, by performing the cooling treatment, the following effects can be expected: a product that is completed by cooling a multilayered object covered by the sheath S, or a multilayered product P that is suitable for storage in a refrigerated state or a frozen state Status and other effects.

The above has exemplified the structure in which one discharge nozzle 42 is provided in the discharge mechanism portion 10a of the multilayer product manufacturing apparatus 10, but the present invention is not limited to this, and the multilayer product manufacturing apparatus 10 may be configured to include a plurality of discharge nozzles 42 . In this case, the inner layer material and the outer layer material are supplied to the discharge nozzle 42 by distributing the inner layer material and the outer layer material supplied by the inner layer material supply device 22 and the outer layer material supply device 32, etc., so that a plurality of times can be discharged at a time. Multiple layers. In addition, the forming mechanism portion 10b, the film feeding mechanism 10b, and the sealing mechanism portion 10d are provided for the plurality of ejection nozzles 42, respectively, and a plurality of products can be simultaneously covered with the sheath S to form a multilayer product P. operation. With this configuration, it is possible to mass-produce multilayer products of the same quality.

In the above-mentioned embodiment, an example in which a multilayer product can be manufactured in a manner that the discharge nozzle 42 is in a fixed state and that the outer skin S is conveyed by the film feeding mechanism 10c while discharging a large number of cases is exemplified. In the form of a layer, the sheath S is formed of the film F formed by the forming mechanism portion 10b. However, the present invention is not limited to this, as long as the discharge nozzle 42 can be relatively moved with respect to the sheath S. That is, in the example shown in this embodiment, the discharge nozzle 42 can be moved up and down, and the multilayer nozzle can be discharged into the outer skin S while moving the discharge nozzle 42 upward.

In the above-mentioned embodiment, the outer skin of the multilayer product is formed by the film F by the forming mechanism portion 10b, and the outer layer is ejected from the ejection mechanism portion 10a while the outer skin is formed by the film F. However, the present invention is not limited to this . That is, instead of providing the forming mechanism portion 10b, a multilayer object may be discharged from the discharge mechanism portion 10a into a separately prepared skin.

Specifically, for example, as shown in FIG. 8 or FIG. 9, a substance made of rubber, film, or resin may be prepared as an outer skin, and a multilayer object may be ejected from the ejection nozzle 42 of the ejection mechanism portion 10 a into the outer skin, and After the ejection is completed, packaging is performed. In the case of using an elastic substance in the outer skin, as shown in FIG. 8, the outer skin is deformed like a balloon by spitting out multiple layers inside the outer skin. This makes it possible to produce a multilayer product having a shape (spherical shape in the example shown) in accordance with the deformation of the material constituting the outer skin. More specifically, in the example shown in FIG. 8, first, as shown in FIG. 8 (a), the outer layer material is discharged in a state where the discharge nozzle 42 is inserted into the outer skin S. As a result, as shown in FIG. 8 (b), the outer layer material is discharged into the outer skin S. Then, the inner layer material is discharged from the discharge nozzle 42 within a predetermined time from a predetermined time (see (c) in FIG. 8). Then, the discharge nozzle 42 is extracted from the outer skin S, and the outer skin S is sealed. It is assembled so as to form a spherical multilayer product as shown in (d) of FIG. 8.

In addition, when the outer skin is a substance that does not deform even if a multi-layered object is incorporated inside, as shown in FIG. 9, it is possible to manufacture a multi-layered product having the same shape as the outer skin. In more detail, in the example shown in FIG. 9, first, the state in which the discharge nozzle 42 is inserted into the outer skin S as shown by an arrow in FIG. 9 (a) is formed. In this state, as shown in FIG. 9 (b), the discharge nozzle 42 is moved in a direction away from the bottom side of the sheath S while the outer layer material is being discharged. As a result, as shown in FIG. 9 (b), the outer layer material is first injected into the outer skin S. Then, from the time when a predetermined amount of the outer layer material is injected into the outer skin S, the inner layer material is ejected while the outer layer material is ejected from the ejection nozzle 42 within a predetermined time (see (c) in FIG. 9). Then, when the discharge nozzle 42 is moved to the outside of the sheath S, it becomes a state where the multilayered object is contained in the sheath S as shown in (d) of FIG. 9. In this state, the outer skin S is packaged to form a multilayer product as shown in FIG. 9 (e).

More specifically, when manufacturing fish cakes or sausages containing fillings, minced meat, which is a raw material for fish cakes or sausages, is supplied as the outer layer material, and as the inner layer materials, the material is used as the filling material. In addition, we are making bread or buns At this time, raw materials for bread or buns are supplied as the outer layer material, and fillings are supplied as the inner layer material. In this way, a multilayered food containing fillings can be produced. In addition, when the heat treatment device 90 is provided as described above, the multilayered object in a state where the filling is wrapped in the minced meat or the raw material can be wrapped by the film F and directly heated in this state to prepare a food. In addition, it can be formed into a state suitable for storage by refrigerating or freezing in a state where the multilayered material containing the filling is enclosed by the film F. In addition, the food produced by the multi-layer product manufacturing apparatus 10 can be cooked in a state in which the film F is wrapped or the film F is removed before eating, which is convenient.

Alternatively, the film F may be formed using an edible material such as rice paper. With such a configuration, it is possible to provide a multilayered food that can be directly consumed without removing the film F.

[Example 2] "Examples of manufacturing apparatus and manufacturing method as industrial products"

The multilayer product manufacturing apparatus 10 described above can also be used for manufacturing industrial products other than food. Specifically, by effectively using the outer layer material, a material having the same viscosity as the inner layer material or a lower viscosity than the inner layer material can be used to make a multilayer product P. The following deodorizing products or fragrances Products or bath products are enclosed in a cylindrical film F, so that they can be provided in the form of a multilayer product P. The above-mentioned deodorant product or fragrance product contains a liquid or gel-like deodorant or fragrance as an internal component. Layer material The outer skin material is used to cover and form a spherical or beaded product. Bath products are products formed by encapsulating inner materials such as soap or bath lotion with a gel-like outer material or a water-soluble outer material. The multilayer product P thus produced can be used by the user after the film F is peeled off during use, or it can be directly performed by the user in a state of being wrapped with the film F.

[Example 3] "Examples of a device and method for manufacturing artificial eggs"

The multilayer product manufacturing apparatus 10 can manufacture artificial eggs by using artificially prepared egg white components and egg yolk components as the outer layer material and the inner layer material, respectively. The cross-sectional shape of the egg thus produced was an egg yolk located at approximately the center portion of the egg white. In addition, when the heat treatment device 90 is provided as described above, the boiled egg can be made by directly heating in a state of being wrapped with the film F.

The outer layer of the egg made as described above is formed of the thin film F, so that the trouble of cracking by a slight impact like the egg in the natural state does not occur. Therefore, the eggs artificially manufactured by the multilayer product manufacturing apparatus 10 are suitable for handling and storage. In addition, since the egg white component and the yolk component can be prepared in an arbitrary ratio, not only eggs in a natural state can be reproduced in the same ratio, but also eggs having a high ratio of the yolk component can be produced. In addition, the quality of the eggs can be made uniform by manually manufacturing the eggs.
