Abstract
Abstract In an apparatus for forming ring-shaped foodstuffs having annular fillings therein, a plurality of forming units are juxtaposed side by side and each comprises concentrical cylinders defining an annular space therebetween for an enclosure material and a cylindrical space inside of the inner cylinder for a filling material and operative parts for discharging the enclosure material and the filling material at predetermined relationships. The plural forming units are connected to a hopper for the enclosure material and another hopper for the filling material, and the operative parts in each of the units are simultaneously operated by a driving mechanism, in which a plate for receiving formed foodstuffs extends in the traverse direction of the units, the plate moving down after receiving the formed foodstuffs and rotating about 180 degrees to drop the foodstuffs on a fryer or a conveyer below the units.

Claim 1
Independent Claim
363 words
In an apparatus for forming ring-shaped foodstuffs having annular fillings therein, said apparatus comprising: a plurality of forming units disposed side by side, each unit comprising an outer pipe, and inner pipe concentrically disposed within said outer pipe with an annular space therebetween, the lower end of said inner pipe extending beyond the lower end of said outer pipe to define a first outlet post of an enclosure material of the foodstuffs, a cylindrical sleeve slidably mounted on the outer circumferential surface of said outer pipe to have a lowered position closing said first outlet port and an elevated position opening said first outlet port, a member urged against the lower open end of said inner pipe to normally close said open end, a piston assembly adapted for pushing a filling material in said inner pipe downwardly against the urging force of said member to form a second outlet port for said filling material between the lower end of said inner pipe and said urged member; a first hopper for storing the enclosure material of the foodstuffs; a second hopper for storing the filling material of the foodstuffs; a first pipe means for feeding said enclosure material in said first hopper into the annular space between the inner and outer pipes in each of said units; a second pipe means for feeding said filling material in said second hopper into said inner pipe in each of said units; a means for simultaneously operating all of the cylindrical sleeves in said units; a means for simultaneously operating all of the piston assemblies in said units; a product receiving plate extending in the transverse direction of the plural units; a means for moving said product receiving plate from the upper position adjacent to said second outlet port in each of said units to a lower position spaced away from the lower end of each of said units; a means for rotating said product receiving plate about 180 degrees while said plate moves down from the lower ends of said units; and means for driving said cylindrical sleeves operating means, said piston assemblies operating means, and said product receiving plate rotating means in predetermined time relationships.
Claim 2
Dependent Claim
363 words
In an apparatus for forming ring-shaped foodstuffs having annular fillings therein, said apparatus comprising: a plurality of forming units disposed side by side, each unit comprising an outer pipe, and inner pipe concentrically disposed within said outer pipe with an annular space therebetween, the lower end of said inner pipe extending beyond the lower end of said outer pipe to define a first outlet post of an enclosure material of the foodstuffs, a cylindrical sleeve slidably mounted on the outer circumferential surface of said outer pipe to have a lowered position closing said first outlet port and an elevated position opening said first outlet port, a member urged against the lower open end of said inner pipe to normally close said open end, a piston assembly adapted for pushing a filling material in said inner pipe downwardly against the urging force of said member to form a second outlet port for said filling material between the lower end of said inner pipe and said urged member; a first hopper for storing the enclosure material of the foodstuffs; a second hopper for storing the filling material of the foodstuffs; a first pipe means for feeding said enclosure material in said first hopper into the annular space between the inner and outer pipes in each of said units; a second pipe means for feeding said filling material in said second hopper into said inner pipe in each of said units; a means for simultaneously operating all of the cylindrical sleeves in said units; a means for simultaneously operating all of the piston assemblies in said units; a product receiving plate extending in the transverse direction of the plural units; a means for moving said product receiving plate from the upper position adjacent to said second outlet port in each of said units to a lower position spaced away from the lower end of each of said units; a means for rotating said product receiving plate about 180 degrees while said plate moves down from the lower ends of said units; and means for driving said cylindrical sleeves operating means, said piston assemblies operating means, and said product receiving plate rotating means in predetermined time relationships.
Claim 3
Dependent Claim
108 words
An apparatus as claimed in claim 1, further comprising: a product separating plate extending in the transverse direction of plural units and having a plurality of circular openings fitted to the lower end portions of said units; a means for spacing said product separating plate above said product receiving plate adapted to sandwich at least a part of said first outlet port and said second outlet port between said both plates while said product receiving plate is at the upper position; and a means for keeping said product separating plate at the lower ends of said units while said product receiving plate rotates by the downward movement thereof.
Claim 4
Dependent Claim
55 words
An apparatus as claimed in claim 1, wherein said member biased against the lower open end of said inner pipe is a cylindrical member having a circular blade edge at the upper circumference thereof; and said product receiving plate has a plurality of circular opening snugly and slidably fitted to each of said cylindrical member.
Claim 5
Dependent Claim
40 words
An apparatus as claimed in claim 1, wherein said means for rotating the product receiving plate comprises toothed wheels fixed to both ends of said plate and racks to be engaged with said toothed wheels when said plate moves down.
Claim 6
Dependent Claim
70 words
An apparatus as claimed in claim 2, wherein said spacing means comprises spacer plates attached to the bottom surface of said product separating plate at both ends thereof, said spacer plates contacting at their lower ends to the upper surface of said product receiving plate; and said keeping means is a plurality of stopper members against which said product separating plate collides while the latter moves down and stops lowering.
Claim 7
Dependent Claim
54 words
An apparatus as claimed in claim 3, further comprising molding cups provided in each of said circular openings in said product separating and receiving plates, said molding cups forming annular walls around a part of said first outlet ports and said second outlet ports when said product receiving plate is at the upper position.
