Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to a preforming process in which dumpling dough, which is continuously extruded by an extrusion device to a predetermined width and thickness, is received by a forming roll of a preforming device and preformed. When molding,
This invention relates to a skewering device that skewers dough that is being preformed.

[Conventional technology]

Conventionally, as a dumpling manufacturing machine, a preforming device with two forming rolls arranged side by side is placed below an extrusion device that continuously extrudes the dough for dumplings to a predetermined width and thickness. A skewering device for skewering the dough being preformed is installed next to the dough, and below the preforming device, the dumpling mass sent from the preforming device is placed on the skewer formed on the arcuate surface of the finishing table. A finishing device is installed between the finishing groove and the finishing groove formed on the circumferential surface of the finishing roll, and finishes the finishing roll into a spherical shape by rotating the finishing roll relative to the finishing table. There is a known method in which the rolls are intermittently rotated in opposite directions, and the push rod of the skewering device is moved by a crank mechanism toward the stopped forming roll to skewer the dough that is being preformed. (Special Publication No. 56-42247).

[Problem that the invention seeks to solve]

However, as described above, the conventional skewering device has a structure in which the forming roll of the preforming device is rotated intermittently, and the push rod is moved by a crank mechanism while the forming roll is stopped to skewer the dough. As a result, the production efficiency was low, and a maximum of about 40 pieces could be produced per minute.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a cam groove on the inner circumferential surface and holds a skewer in a cylindrical body disposed beside the forming roll with its center aligned with the center of the forming roll. A large number of retaining grooves and sliding grooves are arranged in a straight line in the circumferential direction of the outer circumferential surface, and a skewer roll that rotates in the same direction in synchronization with the forming roll is inserted concentrically with the cylindrical body. In the sliding groove, a pressing member including a push rod and a roller is configured to insert the push rod into the holding groove and insert the roller into a cam groove on the inner circumferential surface of the cylindrical body so as to be freely slidable. The cam groove is continuous in the circumferential direction of the cylindrical body, and
The structure is formed between a skewering position closest to the holding groove and a retracted position parallel to the axis of the cylindrical body and separated from the skewering position by a distance approximately equivalent to the length of the skewer. .

[Effect]

The forming roll of the preforming device receives the dough continuously extruded from the extrusion device to a predetermined width and thickness, and preliminarily forms the dough. On this occasion,
The skewer roll of the skewering device rotates synchronously and in the same direction as the forming roll. When the skewer roll rotates relative to the cylindrical body in this way, the roller moves along the cam groove, so the pressing member moves within the sliding groove, and the skewer fed into the holding structure is directed by the push rod toward the forming roll. move it and pierce it through the preforming dough. The pressing member that pierces the fabric with a skewer returns to its original state by the action of the cam groove and rollers.
Pushushurotsudo retreats. When the push rod retreats, a new skewer is fed into its holding groove,
The fabric is pierced by the next movement of the pressing member. Further, the cam groove is continuous in the circumferential direction of the cylindrical body and is between a skewering position closest to the holding groove and a retracted position separated from the skewering position by a distance approximately equivalent to the length of the skewer. Because of this, the pressing member can be moved in the longitudinal direction of the skewer at a specific timing synchronized with the rotation of the forming roll and the skewer roll.
