To do.

Two sets of shutter devices 6 are provided along the width direction so as to correspond to the superposition nozzle device 5. Each shutter device 6 is provided with a detachable shutter piece 62 below the main shaft 61A of the four shutter rotation shafts 61 projecting downward from the lower surface of the drive box 22, and is fixed by a nut member. The upper parts of the main shafts 61A of the rotary shafts 61 are rotatably attached to the lower box body 22B of the drive box 22 via bearings 64 and seal members such as oil seals. It arrange | positions at equal intervals on the periphery centering on the communicating hole 23. FIG. The four shutter pieces 62 surround the shutter opening 63 so that the shutter opening 63 can be opened and closed. As described above, since the superposition nozzle device 5 can be positioned and attached to the drive box 22 on which the shutter rotation shaft 61 is disposed, the center of the superposition nozzle device 5 (synonymous with the center of the discharge port) and the shutter opening 63 are arranged. It becomes possible to match the center with the same axis.

In the shutter piece 62, two identically shaped cutting blades 68 and a cutting blade 69 are provided symmetrically with respect to the rotation center axis of the main shaft 61A of the shutter rotation shaft 61. Each cutting blade 68 and cutting blade 69 have a required thickness, and when the shutter opening 63 is closed, the first food material D1 wraps the second food material by applying a surface pressure to the rod-shaped food dough D. However, a convex surface 68A and a convex surface 69A are formed as working surfaces for cutting the rod-shaped food dough D, and a concave surface 68B that enables rotation of the shutter piece 62 on the opposite side of the cutting blade 68 through the tip of the cutting blade 69, A concave surface 69B is formed. Further, the tips of the cutting blades 68 and the cutting blades 69 are configured to contact the adjacent convex surfaces 68A and 69A when the shutter piece 62 rotates. Therefore, when the shutter rotation shaft 61 is rotated once, the shutter opening 63 formed by surrounding the shutter piece 62 opens and closes twice, and the shutter device 6 performs the cutting operation twice (see FIG. 7). ).

Here, the rotation mechanism of the shutter piece 62 will be described. Each shutter rotation shaft 61 includes an eccentric shaft 61B that is eccentric with respect to the main shaft 61A. Inside the drive box 22, a plate member 66 is attached to the eccentric shaft 61B via a bearing 65 so as to be eccentrically rotatable in the horizontal direction. A control motor M4 for eccentrically rotating the plate member 66 is attached to the lower surface of the end portion (right side in FIG. 6A) of the lower box body 22B of the drive box 22.

In addition, an eccentric shaft 67B that is eccentric with respect to the main shaft 67A is provided on the upper portion of the plate rotation shaft 67. The eccentric shaft 67B has a plate member 66 attached thereto via a bearing 65 so as to be eccentrically rotatable. The eccentric amounts of the main shafts and the eccentric shafts of the shutter rotation shaft 61 and the plate rotation shaft 67 are the same. By rotating the plate member 66 supported in this manner eccentrically by the control motor M4, the respective shutter rotation shafts 61 are rotated synchronously, and the shutter pieces 62 of the respective shutter devices 6 are rotated. This plate member 66 rotates eccentrically below the plate member 57 so as not to interfere with the eccentric rotation of the plate member 57 that rotates the gear rotation shaft 54.

The shutter piece 62 of the shutter device 6 can be controlled to rotate continuously or intermittently at a required rotational speed. In the case of intermittent rotation, for example, the shutter is stopped at a position where the four shutter pieces 62 are arranged to form a substantially square shape, and the shutter opening 63 is opened to the maximum (FIG. 7A). )), Rotating at a required rotational speed set based on a command from the control device 8, the tips of the cutting blades 68 of the shutter pieces 62 are gathered at the center of the shutter opening 63 to close the shutter opening 63 (see FIG. 7 (B)), and further rotating each shutter piece 62 to widen a new shutter opening 63, each shutter piece 62 stops again at a position rotated 180 degrees from the standby position (FIG. 7C). Thus, one encapsulated food P can be divided from the rod-shaped food dough D continuously extruded from the polymerization nozzle device 5. And the shutter piece 62 divides | segments the next foodstuff P by the closing operation | movement of the cutting blade 69 by rotating 180 degree | times similarly to the said operation | movement. In this way, the shutter piece 62 continues to rotate in one direction, whereby the opening and closing of the shutter opening 63 is alternately repeated to produce a plurality of encapsulated foods P.

In the food production apparatus 1, a shutter piece 62 is disposed at a distance from the lower surface of the outer nozzle base 36 of the polymerization nozzle device 5, and the shutter piece 61 is fixed to the polymerization nozzle device 5 without moving up and down. . As described above, the standby time of the shutter piece 62 (or the ratio of the standby time in the rotation range of 180 degrees) is relatively long, and the rotation time of the shutter piece 62 (or rotation time in the rotation range of 180 degrees). The tip of the shutter piece 62 does not stop near the center of the shutter opening 63, and preferably passes through the center at the highest rotational speed of the shutter piece 62. Thus, by forming the new shutter opening 63, it is possible to divide the encapsulated food P without hindering the flow of the rod-shaped food dough D continuously extruded from the polymerization nozzle device 5.

The conveying device 7 uses a belt conveyor in which two conveying belts 71 are run in parallel, and is detachably attached to the main body frame 2 below each shutter device 6. In addition, the conveying device 7 includes a cradle 72 whose vertical position can be adjusted at a position corresponding to the lower side of the shutter device 7 inside the conveying belt 71, and the lower surface of the shutter piece 62 and the traveling surface of the conveying belt 71. The distance from the (upper surface) is settable. The transport belt 71 is continuously driven at a required transport speed by the control motor M5 or intermittently in response to the cutting operation of the shutter device 6, and the packaged food P divided by the shutter device 6 is transported downstream. Transport to.

Although the shutter device 6 according to the first embodiment has been described with the configuration in which the shutter piece 62 including the two cutting blades 68 and the cutting blade 69 is rotated in one direction, the embodiment of the present invention is limited to this. It is not a thing. For example, in the shutter device 6 according to the second embodiment of the present invention, the shutter rotation shaft 61 does not rotate in one direction, but reciprocates (synonymous with rotation) within a required angle range. . That is, a swinging shutter is used. In addition, the same code | symbol is provided to what has the structure and function similar to the structure which concerns on 1st Embodiment, and the overlapping description is abbreviate | omitted.

The shutter device 6 includes six shutter rotation shafts 61 arranged at equal intervals on a circumference centered on the communication hole 23 of the drive box 22 in a plan view, and a shutter piece on a main shaft 61A of each shutter rotation shaft 61. 81 is detachably fixed. The shutter piece 81 has a required thickness, and two action surfaces 81A and 81B for covering and cutting the rod-shaped food dough D when the shutter opening 63 is closed are symmetrically arranged via the tip of the shutter piece 81. I have. The front end of the shutter piece 81 has a structure in contact with the action surface 81A of one adjacent shutter piece 81 and the action surface 81B of the other adjacent shutter piece 81.

Further, the control motor M4 for driving the shutter device 6 is controlled by the control device 8 so that its output shaft reciprocates within a range of a required angle, and the plate member 66 reciprocates by eccentric rotation so that the shutter rotation shaft 61 is rotated. Is reciprocated. The shutter piece 81 stops at a position (referred to as one reciprocating end) where the six shutter pieces 81 are arranged so as to form a substantially hexagon, and waits with the shutter opening 63 fully opened ( (See FIG. 8 (A)), rotating at a required rotational speed set based on a command from the control device 8 (synonymous with rocking), and the tips of the shutter pieces 81 are gathered at the center of the shutter opening 63 to form a shutter. The opening 63 is closed (see FIG. 8B), and each shutter piece 81 is rotated by a required angle from the standby position while continuing to rotate each shutter piece 81 to expand a new shutter opening 63 (the other reciprocation). It stops again (referred to as an end) (see FIG. 8C). One covered food P can be divided from the rod-shaped food dough D continuously extruded from the polymerization nozzle device 5 by the shutter piece 81 swinging in the forward path. Then, after the shutter piece 81 has stopped for a required time, the shutter piece 81 rotates in the opposite direction to the above operation and swings the return path to divide the next food to be encapsulated P. One of the pieces shown in FIG. Return to the round-trip end. That is, when the shutter piece 81 reciprocates once, the shutter opening 63 opens and closes twice to divide the two food products P from the rod-shaped food dough D. In this way, the shutter piece 81 repeats reciprocating rotation, whereby the opening and closing of the shutter opening 63 is alternately repeated to produce a plurality of encapsulated foods P.

As can be understood from the above description, when the food production device 1 removes the polymerization nozzle device 5 from the drive unit 21, the communication hole 23 of the drive box 22 has no unevenness such as a step. Easy to clean. Furthermore, since the drive box 22 can have a highly airtight structure, it can be washed with high-pressure water.

In addition, the superposition nozzle device 5 and the shutter device 6 are arranged concentrically in a plan view by the positioning means, and even if the superposition nozzle device 5 and the shutter device 6 are repeatedly attached to and detached from the drive box 22, they are not displaced. It is possible to install. Moreover, the superposition | polymerization nozzle apparatus 5, the shutter apparatus 6, and the drive part 21 are provided integrally, and can simplify a structure compared with the conventional foodstuff manufacturing apparatus.

The description of the food production apparatus 1 according to the embodiment of the present invention is generally as described above. However, the present invention is not limited to this, and various modifications can be made within the scope of the claims. For example, in the above description, the case where the encapsulated food P in which the second food D2 is included inside the first food D1 is manufactured has been described. However, only one of the food feeding devices is provided, and one type of food is used from the nozzle device.
