The control part 10e controls the operation|movement of the above-mentioned discharge mechanism part 10a, the shaping|molding mechanism part 10b, the film conveyance mechanism 10c, and the sealing mechanism part 10d. That is, the control unit 10e executes operation control of the inner layer material supply device 22 and the outer layer material supply device 32 constituting the discharge mechanism portion 10a, and performs supply control of the inner layer material and the outer layer material. In addition, under the control of the discharging mechanism unit 10a, the multilayered material is transferred to the film F by controlling the operation of the molding mechanism unit 10b, the film conveying mechanism 10c, and the sealing mechanism unit 10d according to the discharging condition of the multilayered product. It is packaged by the formed outer skin (S), and it is set as the multilayer product (P).

≪About the manufacturing method of the multilayer product (P)≫

Hereinafter, the manufacturing method of the multilayer product P performed under the operation control by the control part 10e is demonstrated in detail, referring the flowchart shown in FIG. 5 and the timing chart shown in FIG.

(Step 1)

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

(Step 2)

In step 2, under the control of the control part 10e, the operation|movement which forms the shell S with the film F is started. Then, the control flow proceeds to step 3.

(Step 3)

In step 3, supply of the outer layer material by the outer layer material supply device 32 is started (refer FIG. 6). Thereby, in the discharge nozzle 42 provided in the discharge part 40, the gap formed between the inner-layer material discharge cylinder 52 and the outer-layer material discharge cylinder 54 is discharged downward (outer layer material discharge start process). .

(Step 4)

In step 4, after the discharge of the outer layer material was started in step 3, it is checked whether or not a predetermined time t3 (refer to FIG. 6) has elapsed. Here, the predetermined time t3 is set in consideration of 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 material. It is also possible to start discharging the outer layer material and the inner layer material at the same time (t3 = 0) without setting t3. If progress of the predetermined time t3 is confirmed in step 4, the control flow advances to step 5 (inner layer material discharge start process).

(Step 5)

In step 5, the operation of discharging the inner layer material downward from the inner layer material discharge tube 52 of the discharge nozzle 42 is started while continuing the discharge of the outer layer material started in step 3 described above. That is, from the timing delayed by the predetermined time t3 from the start of discharge of the outer layer material in step 3, in addition to the discharge of the outer layer material, the discharge of the inner layer material is also started.

(Step 6)

In step 6, after starting discharging of the inner layer material in step 4, it is confirmed whether or not a predetermined time t4 (refer to FIG. 6) has elapsed. The predetermined time t4 is appropriately adjusted according to the size (length) of the multilayered product to be manufactured. When the elapse of the predetermined time t4 is confirmed in step 6, the control flow advances to step 7.

(Step 7)

In step 7, the rotation direction of the rotor 102 of the inner-layer material supply apparatus 22 is switched over the predetermined time t5 to the reverse direction to the time of the discharge of an inner-layer material. That is, as shown in FIG. 6 , in step 6, the control signal rotated in the opposite direction from that until the elapse of time t4 is confirmed is output as a signal for controlling the rotor 102 . Thereby, the inner-layer material supply apparatus 22 performs the operation|movement of returning the inner-layer material which has been supplied toward the discharge nozzle 42 in the period up to step 6. When the predetermined time t5 has elapsed after the start of the returning operation of the inner layer material, the control flow advances to step 8 .

(Step 8)

In step 8, the rotation of the rotor 102 which was operating in the direction of returning the inner layer material is stopped (steps 7 to 8: inner layer material discharge stop process). Thereafter, the control flow proceeds to step 9 .

(Step 9)

In step 9, it is checked whether or not a predetermined time t1 (refer to FIG. 6) has elapsed after the start of discharging the outer layer material. Here, the discharge of the inner layer material has been completed up to step 8 described above, but the discharge of the outer layer material has not yet been completed and is continuing. After that, when it is confirmed that the predetermined time t1 has elapsed after starting the discharging of the outer layer material, the control flow advances to step 10 .

(Step 10)

In step 10, the rotational direction of the rotor 202 provided in the outer layer material supply device 32 is switched to the opposite direction to that at the time of discharging the outer layer material over a predetermined time t2. That is, the outer layer material supply device 32 performs the operation of returning the outer layer material that has been supplied toward the discharge nozzle 42 in the period up to the previous step. As shown in Fig. 6, the predetermined time t2 required for returning the outer layer material is sufficiently short with respect to the predetermined time t1. When the predetermined time t2 has elapsed after the start of the returning operation of the outer layer material, the control flow advances to step 11 .

(Step 11)

In step 11, the supply of the outer layer material is stopped by setting the rotor 202 of the outer layer material supply device 32 to a rotation stop state (steps 10 to 11: outer layer material discharge stop process). Thereby, the discharge of a series of multilayered objects performed over Steps 3 to 11 is completed. Then, the control flow proceeds to step 12.

(Step 12)

In step 12, the process which operates the film conveying mechanism 10c and sends the film F (shell S) to the downstream by the length required in order to form the seal|sticker 84 is performed. That is, if a multi-layered material exists in the portion forming the seal 84 , the seal 84 is not easily formed and there is a possibility that the seal 84 is defective. Therefore, the operation of sending the film F to the downstream side by the length required to form the seal 84 is performed in a situation where the discharging of the multilayer material is stopped. Thereby, the series of operations shown in the flowchart of FIG. 5 and the timing chart of FIG. 6 are completed.

As described above, according to the multilayer product manufacturing apparatus 10, the multilayered product is surrounded by the outer shell S formed by the film F formed into a cylindrical shape as the molding mechanism portion 10b, and the sealing mechanism portion 10d is used to It can be sealed by sealing the film F (shell S). Thereby, handling and storage are easy, and it becomes possible to provide the multilayer product P which can handle hygienically. In addition, when the multilayered product discharged from the discharge mechanism portion 10a is surrounded by the outer shell S as described above, even if the multilayered product is manufactured using a soft material, it is easily transported without losing its shape. can do. In addition, since the multilayered material can be provided by being surrounded by the outer shell S, it is possible to easily perform heating or cooling treatment. Thus, according to the multilayer product manufacturing apparatus 10 of this embodiment, it becomes possible to aim at the improvement of the added value of a multilayered product, and diversification of a use.

In this embodiment, the multilayer product manufacturing apparatus 10 is exemplified as one for manufacturing a multilayered product having a double structure in which the outer periphery of the inner layer material constituting the core is surrounded by a single outer layer material, but the present invention is not limited to this not, but it is also possible to make them for the manufacture of multi-structured ones. For example, in the case of manufacturing a multilayer product P having a triple structure comprising a core layer P4, an intermediate layer P5, and an outer layer P6 from the core side toward the outside, as shown in FIG. , similar to the discharge nozzle 42 described above, a nozzle structure 44 in which the first discharge area 42a and the second discharge area 42b are formed by the inner layer material discharge tube 52 and the outer layer material discharge tube 54 . In addition to (also referred to as "the first nozzle structure 44"), the outer layer material discharge cylinder 54 and It is set as the structure in which the 3rd discharge area|region 42c was formed between the 3 discharge cylinders 56. As shown in FIG. Thereby, in addition to the 1st nozzle structure 44, the 2nd nozzle structure 46 comprised by the outer layer material discharge cylinder 54 and the 3rd discharge cylinder 56 is formed. By forming multiple nozzle structures in this way, it becomes possible to achieve further multilayering of the ejected material formed in the ejection mechanism portion 10a.

As described above, according to the multilayer product manufacturing apparatus 10, a material having a viscosity equal to or lower than that of the inner layer material can be used as the outer layer material. Therefore, according to the multilayer product manufacturing apparatus 10, a multilayer product P in which the outer layer material is made of a material having a lower viscosity than the inner layer material, which could not be produced in the conventional packaging bean jam product manufacturing apparatus or the like, is manufactured. thing becomes possible

As described above, in the multilayer product manufacturing apparatus 10, in the manufacturing process of the multilayer product P, the multilayer material discharged by the discharge mechanism part 10a is sealed in the tubular film F in the seal 84. ) is to be formed, and supply control to terminate the supply of the inner layer material and the outer layer material at the previous timing. By carrying out such control, the possibility that the multilayer material adheres to the location where the seal 84 is to be formed on the film F is reduced, and the occurrence of defects such that the seal 84 cannot be formed well is suppressed. can

Moreover, in the multilayer product manufacturing apparatus 10, as the inner-layer material supply apparatus 22 and the outer-layer material supply apparatus 32, what was equipped with the uniaxial eccentric screw pump mechanisms 100 and 200 is employ|adopted. Thereby, the supply state of the inner layer material and the outer layer material can be controlled with high precision, and the inner layer material and the outer layer material can be discharged in an appropriate amount and timing in manufacturing a multilayer food product. Therefore, according to the multilayer product manufacturing apparatus 10, it becomes possible to further improve the manufacturing quality of a multilayer food product.

Further, 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 are both by adjusting the rotation direction of the rotors 102 and 202, so that the inner layer material; It is possible to appropriately change the flow direction of the outer layer material. Therefore, even when a material with low viscosity is used as the inner layer material and the outer layer material, by rotating the rotors 102 and 202 reversely when the supply of each material is stopped, unexpected dripping occurs and the multilayer food accompanying the dripping quality deterioration can be prevented. 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 have a very simple device configuration. Thereby, it becomes possible to aim at suppression of the manufacturing cost of the multilayer product manufacturing apparatus 10, and the improvement of maintenance characteristic.

In the multilayer product manufacturing apparatus 10, the inner layer material supply device 22 and the outer layer material supply device 32 are provided with the uniaxial eccentric screw pump mechanisms 100 and 200, so that the inner layer material and the outer layer material are provided. It is possible to precisely control the start and end of the discharge. Therefore, as described above, after the start of supply of the outer layer material by the outer layer material supply device 32, the supply of the inner layer material by the inner layer material supply device 22 is started at a timing that has elapsed only a predetermined time t3, and the outer layer Assuming that the supply of the inner layer material by the inner layer material supply device 22 is terminated at a timing earlier than the time t1 from the start to the end of the supply of the outer layer material by the material supply device 32, a high-quality multi-layer food can be obtained It becomes possible to manufacture stably.

In addition, as shown by the control flow shown in FIG. 5, the manufacturing method of the multilayer product P of the above-mentioned embodiment is an outer layer material discharge start process (step 3), an inner layer material discharge start process (step 5), and an inner layer Although the example in which each process of the material discharge stop process (steps 7-8) and the outer layer material discharge stop process (steps 10-11) is sequentially performed is shown, it may add another process to this process. Specifically, after the outer layer material discharge start step and before the inner layer material discharge start step, the outer layer material suction step of operating the rotor 102 of the inner layer material supply device 22 in the reverse direction to the inner layer material discharge time by a predetermined amount It is possible to provide

By providing the above-described outer layer material suction step, after the outer layer material discharge start step, the outer layer material discharged from the outer layer material discharge tube 54 of the discharge nozzle 42 and adhered to the distal end is discharged from the inner layer material discharge tube 52 . is aspirated on the inside of Therefore, before the inner layer material discharge start step, the tip of the inner material discharge cylinder 52 is filled with the outer layer material to some extent. In such a state, when the manufacturing process shifts from the outer layer material suction step to the inner layer material discharge start step, the outer layer material filled in the tip of the inner layer material discharge tube 52 is discharged, and then the inner layer material is discharged. Therefore, the multilayer product P produced in this way has a structure in which the lower portion of the inner layer material is reinforced by the outer layer material discharged from the inner layer material discharge tube 52 immediately after the start of the inner layer material discharge start process. Thereby, under the influence of the weight of an inner layer material, etc., it becomes possible to suppress manufacturing defects, such as an inner layer material leaking from the bottom side of the multilayer product P, and to contribute to the improvement of a yield.

The above-described multilayer product manufacturing apparatus 10 is capable of manufacturing a multilayer product P surrounding a multilayer product with a shell S formed of the film F, but heat treatment or sterilization treatment for the multilayer product P, etc. It is also possible to make it possible to add any post-processing of Specifically, as shown by the dashed-dotted line in Fig. 1, a heat treatment apparatus capable of performing either or both heat treatment and cooling treatment on the multilayer product P surrounding the multilayer material with the outer shell S ( 90) may be installed. With such a configuration, it becomes possible to perform post-processing such as heat treatment such as heat treatment or cooling treatment on the multi-layered product wrapped by the outer skin S, further improving the added value of the multi-layered product P thing becomes possible Specifically, by performing the heat treatment, effects such as a finished product through heat to the multilayered material wrapped with the outer skin S and effects such as a sterilization effect can be expected. In addition, by performing the cooling treatment, effects such as cooling the multi-layered product wrapped with the outer shell S to complete the product, and making the multi-layered product P into a state suitable for storing in a refrigerated or frozen state, etc. can be expected. .

Although the above-described multilayer product manufacturing apparatus 10 exemplifies a configuration in which one discharge nozzle 42 is provided in the discharge mechanism portion 10a, the present invention is not limited thereto, and a configuration in which a plurality of discharge nozzles 42 are provided. can be done as In this case, by dispensing 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., by supplying the inner layer material and the outer layer material to the discharge nozzle 42 at once, It becomes possible to discharge a large number of multilayered materials. In addition, by providing a molding mechanism portion 10b, a film transfer mechanism 10c, a sealing mechanism portion 10d, etc. in each of the plurality of discharge nozzles 42 provided, the multilayered product is surrounded by the outer shell S and a multilayered product ( It becomes possible to carry out the work to be completed in the form of P) in plural and simultaneous progress. By setting it as such a structure, it is possible to mass-produce a multi-layered food product of the same quality.

In the above-described embodiment, while the discharge nozzle 42 is in a fixed state and the outer skin S formed of the film F formed by the molding mechanism portion 10b is sent by the film transfer mechanism 10c, the multilayer Although it has been exemplified that a multi-layered product can be manufactured by discharging water, the present invention is not limited thereto, and it is sufficient if it is possible to move the discharge nozzle 42 relative to the shell S. That is, in the example shown in the present embodiment, the discharge nozzle 42 may be configured to be vertically movable, and the multilayered material may be discharged into the shell S while moving the discharge nozzle 42 upward.

In the above-described embodiment, the multilayered product is discharged from the discharging mechanism portion 10a into the shell formed of the film F while forming the outer skin of the multilayer product with the film F using the forming mechanism portion 10b. However, the present invention is not limited thereto. That is, the multi-layered material may be discharged from the discharge mechanism unit 10a into a separately prepared shell without providing the molding mechanism portion 10b.

Specifically, for example, as shown in FIG. 8 or FIG. 9, a material made of rubber, film, or resin is prepared as a shell, and a multi-layered product is discharged from the nozzle 42 of the discharge mechanism part 10a in the shell. It may be discharged and sealed after discharging is completed. When an elastic material is used as the envelope, as shown in FIG. 8 , the shell is deformed like inflating a balloon by discharging a multi-layered material into the shell. Thereby, it becomes possible to manufacture the multilayered product of the shape (ball shape in the example of illustration) which forms an envelope but matches the deformation|transformation. More specifically, in the example shown in FIG. 8, as shown in FIG. 8(a), the outer layer material is discharged in the state which inserted the discharge nozzle 42 in the outer shell S first. Thereby, as shown in Fig. 8B, the outer layer material is in a state in which it is discharged into the outer shell S. Thereafter, the inner layer material is discharged from the discharge nozzle 42 over a predetermined period from a predetermined timing (see Fig. 8(c)). Thereafter, the discharge nozzle 42 is removed from the shell S, and the shell S is sealed, thereby completing a spherical multilayer product as shown in FIG. 8(d).

In addition, in the case where the outer skin does not deform even when a multi-layered material is introduced therein, as shown in FIG. 9 , it becomes possible to manufacture a multi-layered product that conforms to the shape of the pre-formed outer skin. More specifically, in the example shown in Fig. 9A, first, as indicated by an arrow in Fig. 9A, the discharge nozzle 42 is inserted into the outer shell S. In this state, as shown in Fig. 9(b) , while discharging the outer layer material, the discharge nozzle 42 is moved in a direction away from the bottom side of the shell S. As a result, as shown in Fig. 9B, first, the outer layer material is discharged into the outer shell S. Thereafter, the inner layer material is discharged while discharging the outer layer material from the discharge nozzle 42 over a predetermined period from the timing at which a predetermined amount of the outer layer material is discharged into the outer shell S (see Fig. 9(c)). After that, when the discharge nozzle 42 comes out from the shell S, the multi-layered material is accommodated in the shell S as shown in FIG. 9(d). In this state, by sealing the shell S, a spherical multilayer product is completed as shown in Fig. 9E.
