Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for removing the shell from the tail of a shrimp that has been separated from the body, for example for frying.

Previously, workers had to manually peel the tails of each shrimp. For this reason, work efficiency was extremely poor.

This invention was made by focusing on these conventional problems, and includes a process of cutting along the body axis the abdominal muscle located between the legs of the tail of a shrimp that has been separated from the body, and a step of removing the joint connecting the internodes closest to the tail fan by swinging it in the body side direction; a step of grasping the tail shell on one side of the cutting line; and a step of grasping the tail shell on one side of the cutting line; It is an object of the present invention to solve the above-mentioned problems by including the step of pressing a roller rotating around an axis against the tail to separate the shell from the meat.

The present invention will be explained below based on the drawings. 1 to 7 are diagrams showing an embodiment of an apparatus for carrying out the present invention. Reference numerals 1 and 2 denote a pair of rollers parallel to each other, and one roller 1 is driven and rotated by a drive device (not shown). A belt 3 running in the direction of arrow A is stretched between the rollers 1 and 2, and a plurality of shrimp receivers 4 are attached to the outer surface of the belt 3 at a predetermined distance from each other in the longitudinal direction of the belt 3. The shrimp tail 5 separated from the body in the pre-processing step is supplied to the shrimp receiver 4 (see FIG. 5) at position P1. At this time, the tail portion 5 is placed sideways as shown in FIG. 2, that is, with the legs 6 of the tail portion 5 facing in the running direction of the belt 3. In FIG. 2, 7 is the leg 6 of the tail 5.
This is a cutting mechanism provided on the side shrimp receiver 4, and this cutting mechanism 7 has a pair of cutting blades 8 and 9 that face between the legs 6 of the tail 5 and extend in the body axis direction of the tail 5,
One cutting blade 8 is moved relative to the other cutting blade 9 as shown in FIGS. 3 and 4 by a cam (not shown) provided at a predetermined position on the side of the belt 3,
The abdominal muscle 10 (see FIG. 6) located between the legs 6 of the tail 5 is cut along the body axis of the tail 5 at positions P2 and P3 shown in FIG. In FIGS. 2, 5, and 6, reference numeral 11 denotes a plurality of press members provided on the shrimp receiver 4 on the dorsal side of the tail portion 5, and these press members 1
1 is fixed to a rotating shaft 12, and this rotating shaft 1
2 is rotated by a cam (not shown) provided at a predetermined position on the side of the belt 3. and,
This rotation of the rotation shaft 12 causes the holding member 11 to swing, and as shown in FIG. 2, the holding member 11 is pressed against the cutting mechanism 7 while correcting the curved tail portion 5 into a straight line. This pressing is performed between position P4 and position P5. 13,
Reference numeral 14 denotes a pair of parallel rollers installed above the belt 3, and one roller 13 is driven and rotated by a drive device (not shown). roller 1
A plurality of bancord belts 15 running in the direction of arrow B are stretched between 3 and 14, and when the tail section 5 is located between these bancord belts 15 and the belt 3, the bancord belt 15 Press it against the shrimp tray 4 to fix the position. In FIG. 6, reference numeral 16 denotes a claw, and this claw 16 approaches and separates from the shrimp receiver 4 by a cam (not shown) installed on the side of the belt 3, and the receiver 1 fixed to the shrimp receiver 4

grasp. This grip starts at position P6 and ends at position P7. 19 and 20 are swinging rollers installed on the sides of the belt 3, and these swinging rollers 19 and 20 rotate the tail fan 21 of the tail section 5.
is swung in the lateral direction as shown in FIG. Here, the shell 18 of the shrimp tail 5 consists of a plurality of shell segments 22, as shown in FIG. 4, and each shell segment 22 is connected by a joint 23 located on the body side. Therefore, if the tail fan 21 is swung in the body side direction, the joint 23 closest to the tail fan 21, that is, the joint connecting the first shell segment 22a and the second shell segment 22b, will come off. Become. Reference numeral 24 denotes a shell peeling roller installed below the belt 3, and the outer periphery of this roller 24 has many irregularities formed thereon. This roller 24 is rotated about an axis substantially parallel to the body axis of the tail portion 5 by a drive device (not shown). The rotating direction of the roller 24 is such that the portion close to the belt 3 moves in the opposite direction to the running direction of the belt 3, as shown by arrow C.
25 is a tray provided below the roller 24, and the shell 1 is placed on this tray 25 by the roller 24.
The meat 26 separated from the meat 8 is dropped and stored. 27
is a chute, and this chute 27 discharges the shell 18 that has fallen from the claw 16 to the outside. Reference numeral 28 denotes water jets for washing, and the shrimp tray 4 and the like are washed with water spouted from these jets 28.

Next, the effect will be explained.

Here, description will be given of peeling the tail portion 5 of one shrimp, but similar operations are performed for other shrimp, and a plurality of shrimp are peeled at the same time.

First, the shrimp tail 5 separated from the body is placed horizontally on the shrimp receiver 4 that has reached position P1, as shown in FIG. Belt 3 runs and tail part 5
When the tail portion 5 reaches between the bancord belt 15 and the belt 3, the tail portion 5 is pressed against the shrimp receiver 4 by the bancord belt 15 and is fixed in position. When the belt 3 further travels and the tail 5 reaches position P4, the rotating shaft 12 rotates and swings the presser member 11, straightening the bent tail 5 as shown in FIG. Press against the cutting mechanism 7. The state at this time is shown in FIG. Next, when the tail 5 reaches positions P2 and P3, the cutting blade 8 moves relative to the cutting blade 9 as shown in FIG. is cut along. Next, when the tail 5 reaches position P6, the claw 16 approaches the shrimp receiver 4 and cooperates with the receiver 17 to grip the shell 18 of the tail 5 on one side of the cutting line. Next, when the tail portion 5 contacts the swinging roller 19, the tail fan 21 is swung by the swinging roller 19.
When it comes into contact with the swinging roller 20, it is swung by the swinging roller 20, and the joint 23 closest to the tail fan 21 is disengaged. The state at this time is shown in FIG. Next, at position P5, the presser member 11 swings away from the tail portion 5 as shown in FIG. Next, when the tail portion 5 is further transferred and comes into contact with the rotating roller 24, the meat 26 as shown in FIG.
peels off from the shell 18 while rolling. and,
This meat 26 falls onto the tray 25. On the other hand, nail 1
The shell 18 gripped by the shell 18 is dropped into the chute 27 at a position P7 and then discharged to the outside. next,
After the shrimp tray 4 and the like are washed with water jetted from the jetter 28, they are put to use again.

In the present invention, the shell 18 of the tail 5 may be grasped with the claws 16 after the joint 23 of the tail 5 is disengaged. Also, the claw 16 is omitted, and the claw 16 is
The function may be replaced by the cutting blades 8 and 9.

As explained above, according to the present invention, shrimp can be easily peeled with high efficiency.
