Method and apparatus for stuffing loaf molds

Claim 2

Apparatus for stuffing meat material into a horizontally arranged elongated tubular loaf mold open at one end and closed at the other end, which apparatus comprises: a stationary stuffing horn, a stuffing platform, a stuffing carriage for receiving the mold and movable along the stuffing platform relative the stuffing horn, means mounting the stuffing platform for vertical movement to align the mold with the stuffing horn, means for driving the carriage to position the stuffing horn within the mold at the closed end thereof, control means for connecting the stuffing horn to a pressurized source of meat material, means for actuating the control means to commence discharging meat material from the stuffing horn, the pressure of the meat material being such as to force the mold and carriage to move off the stuffing horn, means retarding the movement of the carriage to assure proper filling of the mold, and means for actuating the control means to end the discharge of meat material from the stuffing horn.

Claim 3

Apparatus as defined in claim 1, wherein said retarding means includes a fluid cylinder mounted on the platform and connected to the carriage, and a retarding circuit connected to the cylinder for controlling the return movement of the carriage.

Claim 4

Apparatus for handling a magazine of loaf molds and stuffing meat material into the molds one at a time, wherein the magazine of loaf molds includes a plurality of horizontally extending and vertically arranged in equally spaced apart relation elongated loaf molds open at one end and closed at the other end, said apparatus comprising: a horizontally extending stuffing platform, means for guidably mounting the platform for vertical movement, means for driving the platform in step-by-step fashion to index same at a plurality of vertical positions, a stuffing carriage mounted for movement along the platform along a path perpendicular to the path of platform movement, said carriage adapted to receive and have secured thereto a magazine of loaf molds, a stuffing horn mounted in superposed relation over the platform and in alignment with the vertical center axes of the loaf molds of a magazine mounted on the stuffing carriage, said stuffing horn being connectable to a source of pressurized meat material, means for driving the carriage toward the stuffing horn so that the stuffing horn enters the open end of the mold and until the stuffing horn is positioned adjacent the closed end of the mold, manually actuated means for controlling the platform drive to index a mold into direct alignment with the stuffing horn and to commence a fill cycle by causing the carriage to move a mold onto the stuffing horn and initiate flow of meat material through the stuffing horn, the pressure of the meat material being such as to drive the carriage towards its home position, and means retarding the movement of the carriage toward the home position to assure proper filling of the mold with meat material.

Claim 5

Apparatus for handling a magazine of loaf molds and stuffing meat material into the molds one at a time, wherein the magazine of loaf molds includes a plurality of horizontally extending and vertically arranged in equally spaced apart relation elongated loaf molds open at one end and closed at the other end, said apparatus comprising: a horizontally extending stuffing platform, means for guidably mounting the platform for vertical movement, means for driving the platform in step-by-step fashion to index same at a plurality of vertical positions, a stuffing carriage mounted for movement along the platform along a path perpendicular to the path of platform movement, said carriage adapted to receive and have secured thereto a magazine of loaf molds, a stuffing horn mounted in superposed relation over the platform and in alignment with the vertical center axes of the loaf molds of a magazine mounted on the stuffing carriage, said stuffing horn being connectable to a source of pressurized meat material, means for driving the carriage toward the stuffing horn so that the stuffing horn enters the open end of the mold and until the stuffing horn is positioned adjacent the closed end of the mold, manually actuated means for controlling the platform drive to index a mold into direct alignment with the stuffing horn and to commence a fill cycle by causing the carriage to move a mold onto the stuffing horn and initiate flow of meat material through the stuffing horn, the pressure of the meat material being such as to drive the carriage towards its home position, and means retarding the movement of the carriage toward the home position to assure proper filling of the mold with meat material.

Claim 6

Apparatus as defined in claim 3, which further includes means for stopping flow of meat material through the stuffing horn just prior to the stuffing carriage reaching home position.

Claim 7

Apparatus as defined in claim 4, which further includes means sensing the stuffing carriage at the home position.

Claim 8

Apparatus as defined in claim 5, wherein said means for driving the stuffing carriage in the direction to position the stuffing horn adjacent the closed end of a mold includes a hydraulic cylinder mounted on the stuffing platform having a piston rod connected to the stuffing carriage.

Claim 9

Apparatus as defined in claim 6, wherein said means for retarding return movement of the stuffing carriage toward the home position includes a hydraulic retarding circuit for said hydraulic cylinder.

Claim 10

Apparatus as defined in claim 7, wherein said means for securing a magazine to the carriage includes a manually operable locking means.

Claim 11

Apparatus as defined in claim 8, which further includes means for sensing the positions of the molds when aligned with the stuffing horn.

Claim 12

Apparatus for stuffing meat material into a magazine of horizontally extending and vertically aligned molds open at one end and closed at the other end, which apparatus comprises a stuffing horn, control means for connecting the stuffing horn to a pressurized source of meat material, support means for said magazine of molds, means mounting said stuffing horn and magazine of molds for relative movement therebetween such that the stuffing horn may be sequentially vertically aligned with each mold and move within each mold and be positioned therein at the closed end thereof, means for driving the stuffing horn and magazine support means such that the stuffing horn is at the closed end of the mold aligned therewith, means for actuating said control means to commence discharging meat material from the stuffing horn and filling the mold aligned with the horn with meat material and thereby cause the stuffing horn and magazine support means to separate until the mold is full of meat material, means retarding the separation of the stuffing horn and magazine support means during the filling of the mold, and means for actuating the control means to end the discharge of meat material from the stuffing horn.

Claim 13

Apparatus for stuffing meat material into a magazine of horizontally extending and vertically aligned molds open at one end and closed at the other end, which apparatus comprises a stuffing horn, control means for connecting the stuffing horn to a pressurized source of meat material, support means for said magazine of molds, means mounting said stuffing horn and magazine of molds for relative movement therebetween such that the stuffing horn may be sequentially vertically aligned with each mold and move within each mold and be positioned therein at the closed end thereof, means for driving the stuffing horn and magazine support means such that the stuffing horn is at the closed end of the mold aligned therewith, means for actuating said control means to commence discharging meat material from the stuffing horn and filling the mold aligned with the horn with meat material and thereby cause the stuffing horn and magazine support means to separate until the mold is full of meat material, means retarding the separation of the stuffing horn and magazine support means during the filling of the mold, and means for actuating the control means to end the discharge of meat material from the stuffing horn.
