[Conventional technology]

Conventionally, as a dumpling manufacturing device, a preforming device with two forming rolls arranged side by side is arranged below an extrusion device that continuously extrudes the dough for dumplings to a predetermined width and thickness. A skewer device is installed next to the dough to pierce the dough during preforming.
The dumplings sent from the preforming device are placed below the preforming device between the finishing groove formed on the arc-shaped surface of the finishing table and the finishing groove formed on the circumferential surface of the finishing roll. A finishing device is provided which finishes the finishing roll into a spherical shape by rotating a finishing roll relative to a finishing table, and a driving device intermittently rotates two forming rolls of the preforming device in mutually opposite directions;
It is known that a skewer is operated while the forming rolls are stopped to pierce the dough being preformed with a skewer (Japanese Patent Publication No. 42247/1983).

[Problem that the invention seeks to solve]

However, as mentioned above, the conventional dumpling manufacturing apparatus is configured such that the two forming rolls of the preforming apparatus are rotated intermittently and the dough is skewered while they are stopped. The problem was that the production efficiency was low, and only about 40 pieces could be produced per minute at most.

[Means for solving problems]

In order to solve the above problems, the present invention provides an extrusion device that continuously extrudes dough for dumplings to a predetermined width and thickness, and a dough extruded from the extrusion device around a forming roll. A press roll is provided which rotates in the opposite direction to the forming roll and preliminarily forms the dough together with the forming roll. A preforming device equipped with a cutting mechanism that cuts into lumps at the final position of the preforming device, and a skewer roll disposed next to the preforming device that rotates in the same direction in synchronization with the forming rolls of the preforming device. A skewering device skewers the dough being preformed while the dough is being preformed, and a skewering device skewers the dough being preformed while skewering the dough. The skewering device includes a finishing device that is inserted between the finishing grooves and finishes the finishing roll into a spherical shape by rotating the finishing roll relative to the finishing table, and the skewering device further includes a movable shaft provided parallel to the rotation axis of the forming roll. supported at the distal end of a support member whose proximal end is supported to be swingable about and movable in the axial direction;

A fitting pin inserted into the rotation center axis is provided parallel to the rotation center axis.

[Effect]

The dough that is continuously extruded from the extrusion device to a predetermined width and thickness enters between a forming roll and a presser roll, and is preliminarily formed by these rolls. At this time, the skewering device pierces the dough being preformed with a skewer while rotating in synchronization with the forming roll in the same direction. Preformed in this way,
Further, the dough pierced with the skewer is cut into lumps by a cutting mechanism provided in the preforming device.
The dumpling block cut by the cutting mechanism falls into the finishing groove formed in the finishing table and finishing roll of the finishing device provided below the preforming device, and is finished into a spherical shape by rotation of the finishing roll with respect to the finishing table. and is discharged to the top. Further, the skewer roll of the skewering device is provided coaxially with the forming roll, and these are connected by a fitting pin at a position radially away from the rotation center axis, so that they rotate in synchronization with each other. be able to.
Further, since the skewering device can swing around the movable shaft or move in the axial direction, the skewering device can be moved in the axial direction as necessary to be placed at a position axially away from the forming roll. It can also be moved laterally by swinging around the axis. Moreover, with such movement, the interlocking state of both rolls by the fitting pin can be easily released or recombined.
