A machine for peeling a shell from shrimp comprising a movement device, a plurality of clamp assemblies mounted on and moved by the device past a number of processing stations. In the first style of processing wherein the entire shell is removed, the operative stations include a cutting station, a deveining station, and a meat removal station. In the second style wherein the tail and the first shell section are allowed to remain on the meat, there is also an operative disjointing station wherein the joint or connection between the first and second shell sections is broken. Each clamp assembly includes a tail clamp, a shell disjointing clamp, and a main body clamp, and cam devices are provided for operating the clamps. An actuating mechanism having an active position and an inactive position is provided, this mechanism having interconnected parts at the disjointing station and at the meat removal station. When in the active position, the mechanism operates the cams at the disjointing station to disconnect the first and second shell sections, and the cams at the meat removal station to disengage the tail clamps. When in the inactive position the mechanism does not operate the disjointing clamps and the tail clamp at the meat removal station is not disengaged.
A machine for peeling shrimp and having a loading station, a cutting station, a deveining station, a meat removal station and a shell removal station, comprising moving means, a plurality of clamp assemblies mounted on and carried by said moving means, each of said clamp assemblies including a body clamp, a tail clamp and a disjointing clamp, said body and tail clamps being operable respectively to clamp the body and the tail of a shrimp when engaged and said disjointing clamp being operable when engaged to break a joint between two shell parts of a shrimp, first cam means mounted adjacent said moving means for engaging said disjointing clamp, said first cam means being movably mounted and movable between an active position where it engages said disjointing clamp and an inactive position where it disengages said disjointing clamp, a second cam means mounted adjacent said moving means adjacent said meat removal station, said second cam means having an active position where it engages said tail clamp and an inactive position where it disengages said tail clamp, and movable connecting means between said first and second cam means for simultaneously moving said first and second cam means between said active and said inactive positions.
In a shrimp cleaning machine comprising a rotatable clamp support drum, a plurality of clamp supports fastened adjacent the periphery of said drum, each of said assemblies including cam actuatable tail holding clamps and disjointing clamps, the improvement comprising a pivot shaft mounted adjacent said drum and having first cams thereon for operating said disjointing clamps, said shaft being rotatable to an active position where said first cams are engageable with said disjointing clamps and to an inactive position where said first cams are displaced from said disjointing clamps, second cam means mounted adjacent said drum for operating said tail holding clamps, said second cam means being movable to an active position where said second cams are engageable with said tail holding clamps and to an inactive position where said second cams are displaced from said tail holding clamps, moving means for moving said second cams to said active position, and connecting means between said pivot shaft and said moving means.
