DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a method for cutting a lying bar-shaped food and the same apparatus, in more detail, relating to such method and apparatus that a predetermined portion of a bar-shaped food lying on a carriage conveyor can be cut with that lying position intact.
2. Prior Art
To date, the present applicant has developed such method and apparatus for continuously producing in automation a cored lump food whose inner food material of a certain kind is coated with an outer skin material of a different kind such as a pounded rice cake or bun with sweet bean paste stuffed therein and cheeseburger, and filed a patent application such as Japanese "Kokai" or Laid-open Patent Application No. 6-217675 therefor. The arrangement of such prior art is that to produce a cored lump food, a multilayered bar-shaped food which is extruded with more than two kinds of food materials concentrically overlaid on one another is introduced into a cutting area of a shutter mechanism enclosed with a plurality of cutter pieces which open and close around said area and a certain portion of the food is circumferentially squeezed and cut by simultaneously operating the respective cutter pieces so as to close said cutting area. This has greatly improved the efficiency of producing a cored lump food.
However, with such prior method and apparatus as mentioned above, it has been found inconvenient in use when a soft food material is processed because a bar-shaped food extruded from a nozzle is vertically extruded downwards and is performed cutting operation by the shutter mechanism disposed below the nozzle so that the food is elongated or torn off during the extrusion due to its self-weight, with the result that a normal cutting operation can not be performed.


SUMMARY OF THE INVENTION

Thus, the present invention is to provide a method and apparatus for cutting a lying bar-shaped food of any kinds to enable a required portion of the food to be cut without being elongated or torn off.
The present invention is also to provide such method and apparatus to enable a bar-shaped food to be efficiently cut without being elongated or torn off while the food is continuously conveyed without intermission.
Further, the present invention is to provide such method and apparatus for forming a bar-shaped food without affecting the sticky and elastic nature of bread dough and the like due to its glutinous substance and cutting a required portion of such food, which can resolve such processing troubles as mentioned above.
To solve the above issue, the present invention adopts a method for cutting a lying bar-shaped food wherein the bar-shaped food (F) is introduced into a cutting area (10) of a shutter mechanism (1) enclosed with a plurality of cutter pieces (C) which simultaneously open and close around said area and a predetermined portion of said food (F) is cut by closing said area, said method comprising the steps of transferring at least a tip end portion of said food (F) from a downstream end portion (D) of a take-in conveyor (2) to an upstream end portion (U) of a take-out conveyor (3) by delivering said food towards said cutting area (10) with said food mounted on the take-in conveyor (2) while inserting the downstream end portion (D) into the area (10) in an open position so that it approaches to said end portion (U) of the take-out conveyor (3) and retreating the downstream end portion (D) from the area (10) by retracting the downstream end portion (D) with the tip end portion of the food (F) mounted on the take-out conveyor (3), and cutting a predetermined portion of the food (F) by closing the area by means of the operation of the cutter pieces (C) so as to form a cut food (G), said cut food (G) being issued out by said take-out conveyor (3).
Moreover, to solve the above issue, the present invention adopts an apparatus for cutting a lying bar-shaped food wherein the bar-shaped food (F) is introduced into a cutting area (10) of a shutter mechanism (1) enclosed with a pluralit
