Technical Field

The invention relates to the technical field of food machinery, in particular to a poultry shank bone and meat separating device and a separating method thereof.

Background

The lower leg of the poultry generally refers to the lower leg part of the poultry such as chicken, duck, goose and the like. Generally, the meat of the lower leg of the bird is turned over so that the bone of the lower leg of the bird is exposed, thereby forming a tulip shape called "tulip" which is eaten by frying. The tulip is popular because it not only has good appearance, but also can be eaten only by holding the bone with one hand.

Generally, the bone and meat separation of the lower legs of the poultry is a manual operation, which also includes the production of tulip, and the manual bone removing work is tedious and needs a large amount of working hours. Therefore, it is required to automate the bone removal work to reduce the labor burden of the worker and to reduce the man-hours.

Preferably, in the third step, the gap between the stripping assembly and the lower leg bone part of the poultry needs to be detected, and when the gap is below a threshold value, the fourth step is carried out to cut off the meat part adhered to the large end of the lower leg of the poultry.

By adopting the technical scheme, when the gap between the stripping assemblies is increased from the threshold value to not exceed the threshold value, the second end bone block passes through the stripping assemblies, and the second cutter moves towards the bone, so that the bone is cut off from the bone; even if the length of the bone meat is different, the yield of the meat part obtained from each bone can be improved by adjusting the time for cutting each bone meat.

Preferably, in the third step, the elastic force is set to a first elastic force when a gap between the exfoliating assembly and the poultry calf bone is below a threshold value, and is set to a second elastic force when the gap between the exfoliating assembly and the poultry calf bone is above the threshold value, the first elastic force being greater than the second elastic force.

By adopting the technical scheme, the elastic force applied to the boned meat by the stripping component can be changed; during the peeling and cutting, by applying a first relatively large elastic force to the meat piece to stably support the bone meat, the peeling assembly gap becomes not more than the threshold value, and the meat portion can be firmly peeled and cut; when the gap between the stripping assemblies exceeds a threshold value due to the passing of bones between the stripping assemblies, the second elastic force is applied to support the bone and meat, the risk that the stripping assemblies damage periosteum and fragments attached to the bone parts can be eliminated, the bone fragments can not be mixed into the meat part, and the product quality of the bone-free meat is ensured.

And thirdly, the suspended poultry shanks at the second station are transposed to the third station through rotation of the turntable, the stripping assembly is inserted into the round notches of the poultry shanks under the action of the air cylinder, the elastic supporting piece 6 elastically supports the stripping assembly, the stripping driving piece 7 drives the stripping assembly to strip the meat parts on the poultry shanks, and in the process, the stripping assembly applies elastic force to the poultry shanks.

The stripping assembly comprises a first stripping part 4 and a second stripping part 5, the first stripping part 4 is arranged on the third station, and the first stripping part 4 strips the meat part on the lower leg of the poultry to the middle position of the bone part of the lower leg of the poultry; then the suspended poultry shanks at the third station are transposed to the fourth station through rotation of the turntable, the second stripping part 5 is installed on the fourth station, and the second stripping part 5 strips the meat part in the middle of the poultry shank bone part to the large end part of the poultry shank.

In addition, a detection assembly is arranged on the station four, the gap between the second stripping part 5 and the lower leg bone part of the poultry is detected, and when the gap is below a threshold value, the meat part adhered to the large end of the lower leg of the poultry is cut off.

The elastic force is set to a first elastic force when the gap between the second stripping member 5 and the avian calf bone portion is equal to or less than a threshold value, and is set to a second elastic force when the gap between the second stripping member 5 and the avian calf bone portion is greater than the threshold value, the first elastic force being greater than the second elastic force.

And fourthly, the shanks of the hung poultry at the four positions of the station are transposed to the five positions of the station by rotating the turntable, and the tendons adhered to the large ends of the shanks of the poultry are cut off by the second cutter 8, so that the bone and meat separation of the shanks of the poultry is completed. Wherein the second cutter 8 is a single circular knife cutting assembly. At this station, the meat of the lower leg of the bird falls into the collector 12, the second cutter 8 is away from the lower leg of the bird, and only the bone of the lower leg of the bird remains on the gripper 2.

In addition, if the lower legs of the poultry are made into a tulip mode, the station five idles and does not work.

Then, the suspended poultry shanks at the fifth station are transposed to the sixth station by rotating the rotary table, and the poultry shanks are pulled down into the collecting device 13 by the pulling-down device 11.

After the primary process of removing bones of the poultry shanks is finished, the rotary table continuously rotates, and the feeding is continuously carried out at one station, so that the separation of bones and meat of the poultry shanks is continuously carried out.

The invention has high automation degree, and forms a plurality of circulating processes so as to complete the bone and meat separation of the poultry shanks and the production of the tulip of the poultry shanks. In the manufacturing engineering of poultry shank bone and meat separation, the risk that the stripping assembly damages periosteum and fragments attached to the bone part can be eliminated, the yield of bone-free meat can be improved, and the quality of the bone-free meat is ensured.
