It is desirable that the conveyor device 21 be configured to perform a lifting movement in synchronism with the lifting movement of the shutter 2 when receiving the food product WA.

Next, an embodiment of the envelope cutting method of the present invention will be described. Step (i) The four shutter pieces 5 are synchronously rotated in one direction by driving the rotary motor 14, and the cutting openings 3 are gradually closed to bring the side surfaces 9 closer to each other [FIG. 6 (a), FIG.
(A), see FIG. 8 (a)]. As a result, the projecting portions 9a of the four shutter pieces 5 are gradually gathered at the center of the cutting opening 3 to press the outer covering material W2 from the circumferential direction, and the connecting portion J constricted to the outer covering material W2. After molding (see FIGS. 7 (b) and 8 (b)), the inner wrapping material W1 is vertically separated by the outer wrapping material W2, and the inner wrapping material W1 is individually covered by the outer wrapping material W2 at the constricted joint portion J. In addition to [see FIG. 8 (b)], the food dough W can be vertically cut and separated by the protruding portion 9a in the covered portion (see FIG. 9). At this time, the sharp portions WS are formed above and below the food dough W on the substantially vertical wall surface 9b.

Step (ii) After the step (i) is completed, the four shutter pieces 5 are synchronously further rotated in one direction by driving the rotary motor 14 so that the four shutter pieces 5 have substantially vertical wall surfaces. The sharpened portion WS of the outer cover material W2 that has been cut and separated vertically by 9b is twisted in one direction to further crimp the sharpened portion WS in the covered portion of the food material W [see FIG. 10 (b)]. By moving the part WS up and down (see FIG. 11), the wrapped food WA can be taken out from the rod-shaped food dough W. Here, the sharpened portion WS is moved up and down to reduce the height of the sharpened portion WS, and the sharpened portion WS is provided at the top and bottom of the food package WA.
The action of pushing in also works [see FIG. 11 (b)].

Step (iii) After the above step (ii) is completed, the rotary motor 1 is fed under the condition where the food dough W is supplied to the cutting opening 3 from above.
The four shutter pieces 5 are synchronously further rotated in one direction by the drive of 4, and the cutting opening 3 is wide open to restore the original state (see FIG. 5). As a result, one cutting of the envelope for the rod-shaped food material W is completed.

Step (iv) After the above step (iii) is completed, the steps (i) to (iii) are sequentially repeated to obtain a rod-shaped food dough W.
It is possible to manufacture a plurality of covered food products WA by performing a plurality of covering cuttings on the above.

According to the above-described embodiment, when the shutter 2 is closed, the side surface 9 squeezes the food dough W and the outer skin material W.
The inner packaging material W1 is covered by collectively moving 2 to the center of the cutting opening and joining, and the food dough W is cut and separated up and down by the projecting portion 9a at the covering and joining portion. This protrusion 9a
Has a function of cutting food dough,
The present invention is not limited to this embodiment, and a sharp shape such as a small protrusion or a knife edge may be used. The sharpened portion (horn) WS, which is a covering joint portion formed by the upper and lower outer covering materials W2, is twisted by further rotating the shutter piece 5, and the covering material W2 is covered. The joint can be crimped to ensure reliability. That is, it is possible to improve the quality of the packaged food WA by increasing the bonding force of the cut portion of the packaged food WA and avoiding the exposure of the inner packaging material W1 from the packaged food WA.

As described above, in the present invention, it is possible to twist the outer skin material while sandwiching it by the substantially vertical wall surface 9b having the pointed portion.
Since there is no substantially vertical wall surface 9b on the side surface 9 shown in the embodiment of the present invention, particularly in the case of a food material having a strong elasticity, the joining force of the cut portion of the wrapped food cannot be sufficiently obtained, and the subsequent production Including the process, the inner packaging material may be exposed from the food to be encapsulated, which is a cause of quality deterioration.

Further, the sharp portion WS gradually disappears as the shutter piece 5 rotates, and the sharp portion WS disappears, and the dough of the sharp portion is pushed into the top and bottom portions of the foodstuff WA to be wrapped, Since no sharpness is left on the surface of the food WA, it is possible to obtain a smooth surface. Further, at this time, the conveyor device 2 for receiving the food wrapped WA
1 is moved up and down in synchronism with the up and down movement of the shutter 2, and when the sharpened portion WS is pushed into the top of the foodstuff WA, the top (upper side) of the foodstuff WA is appropriately brought into contact with the lower surface 8 of the shutter 2. By doing so, the upper surface of the wrapped food product WA is flattened by the lower surface 8 of the shutter piece, and the effect of pushing the outer cover material to the top is further improved.

Further, since the pointed portion WS is integrated with the outer skin material of the top and bottom portions of the food wrapped product WA, for example, the skin around the cut portion is poor due to the cutting of the envelope, and the top and bottom portions which are the cut portions. Even if the food material is such that the outer skin material becomes thinner than other food materials, by selecting a shutter piece that has an appropriate size for the pointed portion, the outer skin material can be coated food with a uniform thickness. Obtainable. The formation of the pointed portion WS is performed by rotational movement of a substantially vertical wall surface, and the size of the pointed portion WS or adjustment of the pressure bonding is adjusted according to the property of the material such as the height and inclination angle of the wall surface. Can be appropriately selected. The one shown in FIG. 12 is an example thereof, and the substantially vertical wall surface has a two-step shape, and the sharpened portion formed when cutting the envelope of the food material can be reliably formed and twisted.

The present invention is not limited to the above-described embodiments, but can be implemented in various ways as follows. That is, the number of the shutter pieces 5 is not limited to four, and may be five as long as it is three or more, and six pieces can be used. Further, each shutter piece 5 is provided with one edge portion, but two edge portions are provided with respect to the rotation axis of the shutter piece so that one rotation of the shutter piece can perform covering cutting twice. Good.

Further, in the present embodiment, the shape of the concave surface 10 of the shutter piece 5 is such that the edge portion 6 gathers in the cutting opening 3 by rotation in one direction as shown in FIG. Even after this, the edge portion 6 is configured to slide and rotate while maintaining the state in which the edge portion 6 is in sliding contact with the recessed surface 10, but at this position, the edge portion 6 does not need to slide in contact with the recessed surface 10. The concave surface may be omitted so as not to interfere with the edge portion 6. However, in this case, it is desirable that the upper surface 7 and the lower surface 8 of the shutter piece 5 have a basic shape such that they are in sliding contact with each other. In the rotation of the shutter piece 5, if the angular velocity of the shutter piece 5 is adjusted during the rotation, for example, the angular velocity of rotation can be reduced or momentarily stopped due to the closing action of the cutting opening, and the covering and cutting effect can be adjusted and improved. Further, although the shutter piece 5 has been described as rotating in one direction, the edge portion 6 gathers at the center of the cutting opening, cuts the food material W, and then reciprocates at a proper position to rotate in a reciprocating manner. But it doesn't matter.

[0027]

According to the present invention, the food dough is pressed from the circumferential direction to form the connecting portion constricted in the outer cover material, the inner cover material is vertically separated by the outer cover material, and the inner cover material is respectively separated by the outer cover material. The food dough is cut and separated at the covered part, and twisted in one direction while sandwiching the sharp part of the outer skin material formed by separating, and further crimping this sharp part, from the rod-shaped food dough Since the encapsulated food can be taken out, it is possible to improve the quality of the encapsulated food by increasing the bonding force of the cut portion of the encapsulated food, avoiding the exposure of the inner packaging material from the encapsulated food. . In addition, since the point of the food dough has a wall surface that is almost vertical enough to add a twist, the height of the wall surface for forming the point of the dough can be selected according to the properties of the food dough. If this is the case, optimum envelope cutting can be performed. Furthermore, since the food dough can be pressed into the wrapped food without the sharp portion, the surface shape of the wrapped food can be smoothly formed.
