LOWER FOLDING DEVICE FOR FORMING DUMPLINGS

TECHNICAL FIELD

The present disclosure relates to a dumpling forming lower folding device, and more particularly, to a dumpling forming lower folding device that receives a noodle sheet for a dumpling skin, cuts the dumpling skin, folds the dumpling skin filled with dumpling filling, and thus forms a dumpling.

BACKGROUND ART

In general, dumplings are made by filling insides of dumpling skins made from wheat flour dough with dumpling filling. In this case, due to difficulty of work of joining the dumpling skins filled with the dumpling filling, in the related art, a person should make the dumplings one by one by hand.

Thus, a lot of time and labor are taken for making the dumplings, and mass production thereof is difficult.

In recent years, to solve this problem, some dumpling forming apparatuses that automatically produce the dumplings have been manufactured. However, a structure thereof is complex, an installation area is large, and thus production capacity is low compared as the installation area.

Further, in a dumpling forming apparatus according to the related art, poor sealing occurs in which, in a process of folding and sealing the dumpling skin filled with the dumpling filling, the dumpling skin is not correctly sealed, and thus the dumpling filling escapes from the dumpling skin.

A dumpling skin seated area “K” on which the dumpling skin cut by the dumpling skin pressing unit 220 is seated may be formed in the upper plate part 221. As illustrated in FIG. 4, a plurality of dumpling skin seated areas “K” may be provided and may be spaced apart from each other in a lengthwise direction of the upper plate part 221. When the dumpling skin folding parts SF and GF are driven, one area of the dumpling skin may be spaced apart from the upper plate part 221.

The upper plate part 221 of the present embodiment may be provided with the protrusion cutter 221a defining a circumference of the dumpling skin seated area “K”. The protrusion cutter 221a may protrude from an upper surface of the upper plate part 221 and may be formed in a circular or elliptical shape.

As illustrated in FIGS. 4 to 8, the dumpling skin folding parts SF and GF may include the support finger SF that primarily presses the dumpling skin and the gathering finger GF that secondarily presses the dumpling skin pressed by the support finger SF and gathers an edge area of the dumpling skin.

In an embodiment, two support fingers SF may be provided and arranged to face each other. The support finger SF may press the dumpling skin in a direction perpendicular to a transfer direction of the dumpling skin pressing unit 220 transferred by the folding moving unit 240.

As illustrated in FIGS. 4 to 7, the support finger SF may be rotated by a preset rotation angle for a first support finger before the gathering finger GF, may press a lower surface of the dumpling skin seated on the dumpling skin seated area “K”, may slightly lifts both sides of the dumpling skin, and then may be stopped without the rotation.

The dumpling skin cutting device 100 may press the noodle sheet for the dumpling skin with the dumpling skin pressing unit 220 of the dumpling forming lower folding device 200. The dumpling skin cut by the pressing of the dumpling skin cutting device 100 may be disposed in the dumpling skin seated area “K”.

The dumpling skin pressing unit 220 moves by the folding moving unit 240 so that the support finger rotating roller 228b and the gathering finger rotating roller 225b may come into contact with the upper surfaces of the support finger support rail part 231 and the gathering finger support rail part 232 of the folding cam rail unit 230.

In this case, as illustrated in FIG. 7B, the two support fingers SF may be rotated by a set rotation angle for the first support finger before the gathering finger GF to press a lower surface of the dumpling skin seated on the dumpling skin seated area “K” so as to slightly lift both sides of the dumpling skin.

Thereafter, as illustrated in FIG. 7C, the four gathering fingers GF may be rotated by a rotation angle for the gathering finger to secondarily press the dumpling skin pressed by the support fingers SF.

Next, as illustrated in FIG. 7D, the two support fingers SF may be rotated by a rotation angle for the first support finger having an angle greater than the rotation angle for the first support finger to strongly press the dumpling skin.

As described above, the dumpling skin may be folded by the raising of the support fingers SF and the gathering fingers GF, and the folded dumpling skin may continuously move to reach the sealing device 300.

The sealing device 300 may press, with the first sealing pad P1 and the second sealing pad P2, the dumpling having the dumpling skin folded by the dumpling forming lower folding device 200, may attach the dumpling skin to the dumpling, and thus may form the dumpling having a final shape.

In this way, the in-line dumpling forming system according to the present embodiment may include the dumpling skin cutting device 100 that forms the dumpling skin by cutting the supplied noodle sheet for the dumpling skin, the dumpling forming lower folding device 200 that is disposed in a lower area of the dumpling skin cutting device 100 and presses and folds the dumpling skin to which the dumpling filling is supplied, and the sealing device 300 that is disposed in an upper area of the dumpling forming lower folding device 200 and presses and seals the folded dumpling skin. Thus, an installation area may be reduced by positioning the dumpling skin cutting device 100 and the sealing device 300 on the upper area of the dumpling forming lower folding device 200. Accordingly, productivity is high compared to the installation area, and the dumpling may be formed into an accurate shape, and thus occurrence of defects may be reduced.

Although the present embodiment has been described in detail with reference to the accompanying drawings, the scope of rights of the present embodiment is not limited to the above-described drawings and description.

In this way, the present disclosure is not limited to the described embodiments, and it is obvious to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present disclosure. Thus, the changes or modifications should belong to the appended claims of the present disclosure.
