Definitions
- the present invention relates to a molding apparatus, a molding system, and a molding method for folding food.
- the present invention relates to a method and a system for forming a folded food by placing an inner material such as cream or jam on a flat dough piece of a viscoelastic dough such as bread dough, folding the dough piece and wrapping the inner material.
- Patent Document 1 A system for molding folded foods has been known for some time.
- the molding system described in Patent Document 1 includes a pair of plates provided with facing recesses.
- the flat bread dough is placed in the recess, and the inner material such as bean paste or cream is placed on the bread dough located above one of the plates.
- the inner material such as bean paste or cream is placed on the bread dough located above one of the plates.
- Patent Document 2 describes a caterpillar conveyor having a mechanism for lifting one end, and a mechanical finger mechanism for holding one end of a piece of bread dough, stretching it, and rotating it to cover the other end.
- the bread dough is placed so that one end in the traveling direction protrudes from the plate of the caterpillar conveyor, and the inner material is discharged onto the bread dough.
- the mechanical finger grips one end of the bread dough and turns it to superimpose it.
- Patent Document 1 requires a work of placing a dough divided into a predetermined size in advance at a predetermined position on a plate body. If the flat bread dough is placed at a position deviated from a predetermined position, the seams after molding are deviated and molding defects occur. Therefore, a step of placing the dough normally by hand is required. Further, even if the bread dough is placed in a predetermined position, the bread dough is inverted without being held during the folding molding, so that the position shift may occur and the shape and quality of the folded food may vary.
- Patent Document 2 has a problem that the gripping of bread dough by mechanical fingers is not stable. Depending on the type and condition of the dough, the amount of dough that sticks out of the plate may vary, and when the plate lifts the dough, the position of the dough may shift due to the weight of the dough. In some cases.
- the devices described in Patent Document 1 and Patent Document 2 have complicated configurations, and are devices specialized only for specific folding molding.
- the dimensions of the folded food, the folding direction, the amount of superposition, etc. can only be processed according to the predetermined mechanical conditions.
- the time required for one molding is relatively long, and it is difficult to increase the number of pieces produced per hour. For these reasons, each of the above devices is difficult to operate in today's food production lines where many varieties are required to be efficiently produced.
- the present invention is a molding device capable of moving one end of a dough piece over the other end to fold the dough piece, and by sucking and lifting one end of the dough piece from above.
- a suction tool to be held and a support tool including a support portion movable below the suction tool are included, and by bringing the suction tool and the support tool closer to each other, one end of the fabric piece is supported by the suction tool and the support portion. It is characterized in that it is gripped between the parts.
- the support portion includes a rotatable roller.
- a pressing tool for pressing the peripheral edge portion of the overlapped fabric pieces by folding the fabric pieces is included.
- a plurality of the suction tools are included, and at least two of the suction tools are arranged so as to be offset in a direction from one end to the other end of the dough piece, and more preferably at least.
- One of the suction tools is arranged above the peripheral edge of the dough piece.
- the present invention is a molding system including any of the above-mentioned molding devices and a moving mechanism for moving the molding device.
- the present invention is a method of folding and molding a dough piece, in which a lifting step of sucking and lifting one end of the dough piece from above by a suction tool and one end of the lifted dough piece are lifted by the suction tool. And the gripping step of gripping by sandwiching and gripping between the suction tool and the support portion arranged below the suction tool, and while holding one end of the dough piece by the suction tool and the support portion, toward the other end of the dough piece. It is characterized by including a superposition step of folding and superimposing the dough pieces by moving the dough pieces.
- a pressing step of pressing the peripheral edge portion of the superposed fabric pieces is further included, and more preferably, after the pressing step, further gripping is performed.
- the molding apparatus for example, when one end of a dough piece flatly placed on a conveying surface or a tray of a conveying device is moved onto the other end to fold the dough piece, the dough piece is folded. Since one end of the dough piece is sucked and lifted and one end of the dough piece is gripped between the suction tool and the support part, one end of the dough piece is firmly gripped by the molding apparatus. Therefore, during the folding molding, the fabric piece is always firmly held (held) by the molding apparatus, and the folding molding can be performed accurately and stably. In addition, it is relatively easy to change the molding conditions such as the folding direction and the amount of superposition.
- the molding apparatus according to the present invention sucks the dough pieces from above and lifts one end thereof, it is possible to continuously fold and mold even the dough pieces spread in a plurality of columns and a plurality of rows without gaps.
- the folding molding can be performed without stopping the transportation of the fabric pieces. Therefore, the number of products produced per hour can be increased.
- the present invention since the present invention has a relatively simple structure and can be molded without using a special transport device, it can be easily introduced into an existing food molding line.
