Description

The present invention relates to a packaged food molding method and apparatus for molding an inner material such as bean paste and delicatessen by using an outer skin material such as bread dough and bun dough.

A molding method in which an inner material is placed on a sheet-shaped outer skin material and the peripheral edges of the outer skin material are gathered together by a shutter means and sealed so as to wrap the inner material has been put into practical use. Is stably molded.

In such a molding method, the peripheral edges gathered when sealing the peripheral edges of the outer skin material are formed into hump-shaped protrusions so as to swell at the sealed portions. Since a molded product having hump-shaped protrusions is inferior in appearance, a technique for molding into a shape without hump-shaped protrusions has been proposed.

For example, in Patent Document 1, when the peripheral edges of the outer skin material are gathered together by the shutter means, the outer skin material is sealed so as to wrap the inner material at the trailing edge portion that closes later than the leading edge portion of the side surface of the shutter piece. It is described that the outer skin material can be molded so as not to protrude above the shutter means at the time of sealing. Further, Patent Document 2 describes that the sealed portion on which the hump-shaped protrusion is formed is pressed against the lower surface of the closed shutter above, and the hump-shaped protrusion is crushed and molded so as to be immersed. ing.

In Patent Document 1, the shape of the sealing surface of the shutter piece is devised so that it does not protrude from above the shutter means, but the fabric remains in the gap of the portion where the closing shutter piece abuts. Protrusions may be formed. Further, in Patent Document 2, the hump-shaped protrusions are crushed so as to be immersed in them, and although the protrusions disappear in appearance, the thickness of the dough of the molded product becomes uneven due to the dough pushed into the inside, and the protrusions are formed in the crushed portion. It is inevitable that the appearance will deteriorate because traces will remain.

Therefore, an object of the present invention is to provide a method and an apparatus for molding a packaged food product, which can reliably mold a sealed portion into a shape without protrusions.

The method for molding a packaged food product according to the present invention includes an arrangement step of arranging the inner material on a sheet-shaped outer skin material, and the peripheral portions of the outer skin material are gathered and sealed so as to wrap the inner material by a shutter means. It includes a sealing step and a shaping step of shaping the sealed portion formed in the sealing step by the shutter means so as to be leveled. Further, in the sealing step, the peripheral edge portion of the outer skin material is sealed without closing the shutter means completely. Further, in the shaping step, the sealing portion is moved downward relative to the shutter means while the outer skin material is supported from below by the support means, and the shutter means is operated to close completely. Shape the sealed part so that it is even.

The packaged food molding apparatus according to the present invention wraps the inner material by controlling the operation in the direction of closing the shutter portion with the shutter portion having a plurality of shutter pieces and the inner material arranged on the sheet-shaped outer skin material. It is provided with a control unit for gathering and sealing the peripheral edges of the outer skin material and controlling the operation of the formed sealing portion so as to close the shutter portion so as to be leveled. Further, a support portion arranged below the shutter portion is provided, and the control unit controls the operation of the support portion so as to support the outer skin material from below when the sealed portion is leveled.

3 to 10 are explanatory views regarding a molding process of the packaged food molding apparatus 1. The explanatory view shows the operation of the discharge portion 4, the presser portion 6, the sealing portion 8, and the support portion 9 related to the molding operation. FIG. 3 shows a state in which the sheet-shaped outer skin material F is thrown onto the receiving member 82 from the carrying-in portion 7. The discharge portion 4 and the presser portion 6 are raised in advance and set to the standby position, and the upper shutter 80 and the lower shutter 81 of the sealing portion 8 are both set in the open state. Further, the support member 94 is set at a position where it can be raised to support the molded product.

In this case, the charged outer skin material F is operated in the closing direction of the upper shutter 80 to be brought into contact with the peripheral portion of the outer skin material F, and the position is adjusted with respect to the central axis of the discharge pipe 40. You may.

FIG. 4 shows a state in which the discharge portion 4 is lowered and the nozzle at the tip of the discharge pipe 40 is in contact with the outer skin material F. The pressing portion 6 also descends together with the discharging portion 4, and the pressing member 60 comes into contact with the peripheral edge portion of the outer skin material F to hold the peripheral edge portion of the outer skin material F with the receiving member 82. The opening / closing member 44 in the discharge pipe 40 is arranged at an elevated position, and is arranged above the connecting portion with the supply unit 3. Therefore, the inner material G supplied from the supply unit 3 through the supply pipe 32 is introduced into the discharge pipe 40 from the connecting portion.

FIG. 5 shows a state in which the opening / closing member 44 in the discharge pipe 40 is lowered to discharge the inner material G. When the opening / closing member 44 is lowered, the inner material G introduced into the discharge pipe 40 is discharged so as to be pushed out toward the outer skin material F. The outer skin material F has a shape in which the central portion is recessed toward the lower support member 94 while the peripheral portion is held by the pressing member 60, and the inner material G is accommodated.

FIG. 6 shows a state in which the discharge portion 4 is raised and the inner material G is arranged on the outer skin material F. The discharge unit 4 is raised to move the tip of the nozzle and the tip of the opening / closing member 44 away from the inner material G. At that time, by raising the opening / closing member 44 while swinging it around the central axis, it is possible to improve the cutting of the inner material G and prevent the inner material G from sagging or the like.

FIG. 7 shows a state in which the peripheral portions of the outer skin material F are gathered together to wrap the inner material G. By operating the upper shutter 80 in the closing direction, the peripheral edges of the outer skin material F held on the receiving member 82 are gathered toward the center.

FIG. 8 shows a state in which the peripheral edge portion of the gathered outer skin material F is sealed. By operating the lower shutter 81 in the closing direction in a state where the peripheral portions of the outer skin material F are gathered together, the gathered peripheral edges are crimped and sealed. In this case, it is preferable that the lower shutter 81 is not completely closed, and the peripheral portion is loosely sealed so that the inner material G is not exposed. FIG. 11A shows a loosely sealed sealed item h. In the sealed portion of the sealed product h, a hump-shaped protrusion t is formed in a gap formed in which the lower shutter 81 is not completely closed. When the lower shutter 81 is completely closed, it is formed as a protrusion in a thinly hanged state, but the protrusion t is formed so as to swell with substantially the same thickness as a whole.

FIG. 9 shows a state in which the position is set for shaping the sealed product h. The support member 94 is lowered by operating the lower shutter 81, which has been sealed, in the opening direction. Therefore, the sealed portion of the sealed product h placed on the support member 94 is positioned so as to move downward relative to the lower shutter 81. In this example, the support member 94 is set to be slightly lowered so as to be displaced below the sealing position of the lower shutter 81. If the amount of downward movement of the support member 94 is determined by trial with an initial value set based on the thickness of the receiving member or the like, the shaping operation can be reliably performed.

FIG. 10 shows a state in which the sealed portion is shaped. By operating the lower shutter 81 so as to close it completely with the position of the support member 94 fixed, the protrusions of the sealed portion are pushed and leveled laterally by each shutter piece. FIG. 11B shows the molded product H. Since each shutter piece is leveled so as to stroke the surface of the sealed product h, the outer skin material does not have an uneven thickness as in the case of crushing the sealed portion, and the shaped portion T has a clean surface without unevenness. Can be finished to.

Then, the shaped molded product H descends while being placed on the support member 94, is conveyed by the conveying belt 90, and is carried out to the next step.

As described above, after the peripheral edges of the outer skin material F are gathered and sealed so as to wrap the inner material G with the shutter, the protrusions formed on the sealed portion are shaped so as to be leveled by the shutter. The thickness of the outer skin material does not become uneven in the sealed portion, and a clean surface without protrusions can be finished.
