Abstract
Method for extracting pin bones from a fillet wherein the pin bones are extracted by a tool having a certain speed relative to the fillet and wherein the tool is displaced at different relative speeds along a first fillet portion where the fillet has pin bones and along a second fillet portion where the fillet has no pin bones.
Claims13
A method of extracting pin bones from a fish fillet, the fillet having a first portion with pin bones and a second portion without pin bones, the method comprising:
- transporting the fillet on transport arrangement at a first displacement speed;
- moving an extraction tool at a second displacement speed that is different than the first displacement speed while extracting the pin bones by gripping and then pulling the pin bones from the first portion of the fillet, the extraction tool being coupled to at least one of a guide and hanger;
- and thereafter
- moving the tool with respect to the second portion of the fillet at a third displacement speed that is different from the second displacement speed;
- wherein the fillet is transported on the transport arrangement in a first direction at the first displacement speed and wherein the extraction tool is moved with respect to the first portion of the fillet in the first direction at the second displacement speed, wherein the second displacement speed is less than the first displacement speed.
A pin bone extractor device for extracting pin bones from a fish fillet having a first portion with pin bones and a second portion without pin bones, the device comprising:
- a transport arrangement transporting the fillet at a first displacement speed;
- an extraction tool extracting the pin bones by gripping and pulling the pin bones from the fillet, the extraction tool being coupled to at least one of a guide and hanger;
- a control device that controls the transport arrangement to transport the fillet at a first displacement speed, controls the extraction tool to move parallel to the transport arrangement and with respect to the first portion of the fillet at a second displacement speed that is different than the first displacement speed while extracting the pin bones from the fillet without cutting the pin bones, and thereafter controls the tool to move parallel to the transport arrangement and with respect to the second portion of the fillet at a third displacement speed that is different from the second displacement speed.
A pin bone extractor device for extracting pin bones from a fish fillet having a first portion with pin bones and a second portion without pin bones, the device comprising:
- a transport arrangement transporting the fillet at a first displacement speed;
- an extraction tool extracting the pin bones by gripping and pulling the pin bones from the fillet, the extraction tool being coupled to at least one of a guide and hanger;
- a control device that controls the transport arrangement to transport the fillet at a first displacement speed, controls the extraction tool to move parallel to the transport arrangement with respect to the first portion of the fillet at a second displacement speed that is less than the first displacement speed while extracting the pin bones from the fillet, and thereafter controls the tool to move parallel to the transport arrangement with respect to the second portion of the fillet at a third displacement speed that is greater than the second displacement speed;
- wherein the fillet is transported on the transport arrangement in a first direction at the first displacement speed and wherein the extraction tool is moved with respect to the first portion of the fillet in the first direction at the second displacement speed;
- wherein the tool is moved with respect to the second portion of the fillet in a second, opposite direction at the third displacement speed;
- and
- wherein the tool abuts the fillet during extraction of the pin bones from the first fillet portion and wherein the tool is separated from the fillet by a clearance distance when the tool is moved with respect to the second portion of the fillet.
