Abstract

The present invention relates to a crab shell removing apparatus increasing the purity of removing a removal part. More specifically, unlike removing a crab shell through a conventional hitting method, the apparatus removes a crab shell through the restraint of progress, and thus, the apparatus is capable of enabling crab shells to be reused and minimizing a twist of a crab body, and also, since a rotating direction of an upper groove roller is the same as a crab entering direction, the apparatus is capable of minimizing a body twist while increasing the efficiency of removing a protruding part around the mouth. To achieve the purpose, the present invention includes: a transfer part transferring a crab; and a crab shell removing part removing back and front shells of the crab transferred on the transfer part. The shell removing part comprises: an upper groove roller located on the upper side of a crab entering surface; and a lower groove roller located on the lower side thereof. As such, when the crab enters between the upper and lower groove rollers, the back and front shells are removed. The lower groove roller has the opposite rotating direction to the crab entering direction, and multiple grooves, which are orthogonal to the rotating direction, are formed on the outer surface of the lower groove roller, and thus, an entering front end part of the back shell is inserted into the grooves to make the back shell removed through the restraint of progress.

More particularly, the present invention relates to a method and apparatus for removing the back skin by progressive papermaking instead of removing the back skin by a conventional striking method, thereby enabling the back skin to be recycled And the rotation of the upper groove rollers is made to be the same as that of the entrance grooves, thereby minimizing the trunk misalignment. In addition, the removal of the removed portions, which can increase the removal rate of the inward projecting portions, ≪ / RTI >

It is known that there are 4,500 species in the world and 183 species in Korea. The crabs are divided into ten limbs among arthropods. The ten legs are functionally divided into a pair of claws and four pairs of walking legs. Crabs vary in their habitat and extrinsic characteristics as well as their species. Crabs have vegetation that crawl on the floor and process the carcasses of marine creatures that fall to the floor, which is also called the sea scavenger.

These crabs are one of the most important fishery resources of our country which is sea of three sides. They are steamed as they are, or boiled in boiling water, and then they are eaten by boiling the body or legs or by using soy sauce. And various types of frozen foods such as crab meat and various frozen foods have been processed and sold.

However, in order to process a crab into various kinds of processed foods, it is necessary to sort the crab different parts of the crab in a hard shell of the crab.

Fig. 1 and Fig. 2 are diagrams showing general crabs.

Referring to the drawings, a portion of a crab is composed of a trunk formed by a back shell 1 and a fold shell (not shown), a pair of legs 2, first to fourth legs 3, 4), and a tactile sense (5).

In order to separate such a crab, conventionally, a worker lifts a cutting knife and manually operates the legs 3 and the legs 2 to walk on the workbench by hand and the legs 2 Not only does it require a lot of labor by cutting and sorting, but also when a worker is injured by a shell of a crab (1), a shell of a crab or a knife in the process of manually cutting a shell of a crab using a knife There were frequent problems.

Accordingly, in order to improve inconvenience caused by manual work, a processing device capable of automatically processing crabs has been proposed in Korean Patent Laid-Open Publication No. 2015-0051461.

Fig. 3 and Fig. 4 are views showing the above machining apparatus.

Referring to the drawings, a conventional processing apparatus includes a transfer section A for continuously transferring a crab, a leg alignment section B for aligning the legs of the crab conveyed through the alignment means, (C) which cuts off the middle part of the body after removing the gills in the inside of the body by removing the gills at the same time, and a second cutter (C) (D) for cutting the divided both side edges of the ridges transported by the transporting means (A).

The first cut-off portion C is rotated by a motor and radially formed on the outer circumferential surface thereof to form a concavo-convex portion 15a. The convex portion 16a is rotated by a motor, And the back skin and the back skin of the crab body which are put between the back skin removing means 15 and the back skin removing means 16 are separated and discharged from the body at the same time .

At this time, on both sides of the guide 2 provided behind the back skin removing means 6, gill removing means 17 rotating in the direction opposite to the crazing direction by the motor are provided so that the gill removing means 7 is provided on both sides And a trunk cutting knife 18 driven by a motor is installed at the center in the rear of the gill removing means 7 to remove the gills from the first and second conveying belts 102 and 106 To cut the middle portion of the trunk of the red debris being transported by the transporting means.

6 to 10 protruding pieces 16a are radially formed on the outer circumferential surface of the center roll so that the back skin of the crab that enters the protruding piece 16a as it rotates is protruded from the protruding pieces 16a As shown in FIG.

In this process, the separation force is very high due to strong striking force between the back skin and the protruding pieces (16a), but there is a disadvantage that the back skin is not recyclable due to high breakage rate of the separated back skin, Problems arise.

Of course, the entrances are supported by a pressure conveyor (not shown) for supporting the legs to a certain extent by pressing both legs thereof, but it is not possible to sufficiently prevent the deformation by the projecting pieces 16a by only the pressure force through the pressure conveyor .

This deviation of the crab causes a problem that the accuracy of the gill removing process by the gill removing means 17 or the trimming process of the trimming margin by the second cut grooves D is lowered in the future.

That is, when the crab's body is torn, the gill removing means 17 does not sufficiently remove the gill, and the trimming of the trunk edge causes other problems in the future.

In addition, as shown in Fig. 2, in the case of the projecting portion 7 such as a stuttering or an undersurface, it is not completely removed by the skin removing means 15 or the back skin removing means 16, It is inconvenient to manually remove it.

Therefore, when the back skin (1) is removed, the body trimming is minimized and the breakage of the back skin is minimized when the back skin is separated, and the removal of the inward protrusion (7) is simultaneously performed at the time of separating the back skin (1) It is necessary to propose a machining apparatus capable of accomplishing this.

Referring to the drawings, an eavescap apparatus 100 according to an embodiment of the present invention includes a feeding unit 10 and a deodorizing unit 20.

The transfer unit 10 is provided to transfer the crab in a state of being seated on the bottom surface. The transfer unit 10 is configured to transfer the crab to the deodorizing unit 20 and the gill removing unit 20 in the course of being transferred to the rear end after the crab is seated at the best end. (30) so that debriding and gill removal are performed.

In an embodiment of the present invention, it is illustrated that the back of the crab is transported toward the bottom on the transporting unit 10, but this is merely an example, and the back shell may be configured to be directed toward the upper side will be.

5 to 6, the conveying unit 10 includes a first conveyor 11 driven by a motor (not shown) and a second conveyor 12 arranged side by side at regular intervals, . The first conveyor 11 and the second conveyor 12 are configured so as to extend from the best end to the rear end of the conveying unit 10 at both leg portions of the crab.

A third conveyor 13 and a fourth conveyor 14 driven by a motor are installed at one end and the other end of the space formed between the first conveyor 11 and the second conveyor 12, 3 conveyor 13 transports the body portion of the crab to the deodorizing portion 20 at a position where the trunk portion of the crab placed at the best end is placed. l

The third conveyor 13 and the fourth conveyor 14 are connected to the first conveyor 14 and the second conveyor 14. The third conveyor 13 and the fourth conveyor 14 guide the legs, 11 and the second conveyor 12 to move at the same speed as that of the first conveyor 11 and the second conveyor 12, the driving force is transmitted from the driving shaft that drives the first conveyor 11 and the second conveyor 12,

On the other hand, a pressure conveyor 10a is installed on the upper part of the first conveyor 11 and the second conveyor 12. The pressure conveyor 10a presses the leg part of the crab to remove the crab, So that the body or the leg portion can be fixedly moved without being twisted.

In addition, a plurality of tension rollers 10b may be provided on the pressure roller conveyor 10a in order to maintain the tension thereof at a predetermined level or more.

The clamp conveyor 10a must be moved at the same speed as the first conveyor 11 and the second conveyor 12 so that the clamping conveyor 10a receives rotational force transmitted to the drive shaft for driving the first conveyor 11. [

On the other hand, the deodorization portion 20 is provided to remove the back skin and the back skin of the crab being transferred onto the transfer portion 10. The deodorization portion 20 is located on the upper side on the entry surface of the crab to be moved The upper grooved roller 21 and the lower grooved roller 22 located at the lower side pass through between the upper grooved roller 21 and the lower grooved roller 22 so that the grooved shell and the crust are removed .

The upper grooved roller 21 has a plurality of groove grooves 21a formed on the outer circumferential surface of the upper grooved roller 21 in a direction perpendicular to the rotational direction, And simultaneously removes the inlet-side projecting portion and the shell of the inlet side of the crab.

The width of the upper groove roller 21 is equal to or smaller than the width of a pair of grooves of the crab in order to minimize damage to the trunk while removing the folds of the crab, Cutting edge processing is performed on the outermost edge of the projecting end 21b projected by the formation of the projections 21a so as to facilitate cutting of the shell and removal of the projection of the projecting end.

The upper grooved roller shaft 21c is engaged with the upper grooved roller shaft 21c on the center of the upper grooved roller 21 and the driving force applied to the driving of the above- And can be rotated.

In addition, the lower groove roller 22 is configured to be located on the lower side of the upper groove roller 21 in a shape similar to that of the upper groove roller 21, so that a crab that enters between the upper groove roller 21 and the upper groove roller 21 is passed through. The rotation direction of the roller 22 is configured to be opposite to the entry direction of the crab.

The width of the lower groove rollers 22 is greater than the width of the upper groove rollers 21 and is equal to or smaller than the width of the crab for blocking the entry of the back rind, 22a) is preferably formed to have a depth of 3 mm to 15 mm in order to minimize breakage of the back skin.

In the case of the lower groove roller 22, the lower groove roller shaft 22b is coupled to the center of the lower groove roller 22 so as to receive rotational force from the outside.

The present invention has been developed in order to solve all three problems of the conventional eavesdropping device as described in the above-mentioned background art. The present invention is characterized in that the configuration of the upper groove roller 21 and the lower groove roller 22, The above three problems can be solved by optimization.

That is, in order to smoothly remove the dorsal skin, the dorsal skin removing means constituted at the lower side only has to adopt a structure having a high hitting strength, so that it is inevitable that the dorsal skin is damaged and the body of the crab which moves is wrong.

However, the lower groove roller 22 according to the present invention adopts a method in which the best end of the back shell of the entering crab is engaged with a plurality of grooves 22a having a somewhat smaller depth and separated from the torso through the progress blocking.

Of course, the lower groove roller 22 having the plurality of grooves 22a formed therein enters the uppermost end portion of the shell, and at the same time, a certain degree of striking is applied to the lower side. However, the striking energy is considerably different from that of the conventional pure striking method do.

This progress blocking method minimizes the impact strength while maintaining the same effect of removing the back skin, thereby enabling the recycling of the removed back skin.

In recent years, the back cover has been widely used as a food decorating material, so that it is possible to recycle resources and diversify the profit structure through the separated back cover.

In addition, such a decrease in the impact strength can minimize not only the recycling of the back skin but also the trimming of the trunk generated during the hitting. Such trunk trimming phenomenon is a cause of deteriorating process efficiency in the subsequent gill removing process or leg cutting process Lt; / RTI >

Therefore, when the body trimming phenomenon occurs, the worker manually aligns the trunk or legs, resulting in a labor cost, etc., and it is difficult to perform a rapid sorting operation, thereby lowering the moving speed of the crab, thereby significantly reducing the overall production efficiency.

The lower groove roller 22 according to the present invention can minimize the trunking phenomenon by removing the back skin by the progress blocking method instead of the hitting method.

In addition, the upper groove roller 21 minimizes the trunk misalignment, as the upper groove roller 21 rotates in the same direction as the entering direction of the crab, And pressurizes at the upper side when the swinging is generated.

The rotation of the crab in the same direction as the crab entering direction leads to a reduction in the size of the trunk and legs when the crab is taken out.

In addition, it is possible to significantly reduce the removal rate of the protrusions of the protrusions such as the dorsum, the dorsal margin, etc. of the existing crab according to the rotation direction of the upper groove roller 21 as described above.

In other words, conventionally, both the upper removing means and the lower removing means are formed in a direction opposite to the entering direction of the crab for reliably removing the rind shell and the back rind, so that when the engaging projection of the crab is engaged with the removal structure of the upper removing means, In some cases, some remnants were left in the trunk.

Separate manpower has been put in place for the removal of such residues, which in turn reduces production efficiency in various respects as described above.

Of course, as the gill removal efficiency which has been succeeding is decreased, the workforce is naturally inputted, and the worker removes the gills and the remnants of the inward projecting portion together.

However, the applicant of the present invention has proposed a technique in which the gill removing unit 30 is constructed of a water spraying method to remarkably increase gill removing efficiency.

Therefore, the configuration of the upper groove roller 21 and the lower groove roller 22 is proposed in order to minimize a large number of attraction forces that have been previously put in order to remove the residual parts of the gill gathers, .

The upper groove roller 21 according to the present invention rotates in the same direction as the entering direction so that the position of the remnant and the portion of the outermost corner 21b of the upper groove roller 21 are exactly coincident with each other It is cut off at the rear portion thereof, so that the inward projected portion is smoothly removed.

On the other hand, the gill removing unit 30 is located on both sides of the deodorizing unit 20, and removes the gill of the crab exposed by removing the back skin from the gill removing unit 30 by jetting high-pressure water and removing or rotating the gill.

The leg cut portion 40 is provided on the transfer portion 10 to cut between the leg portions or both leg portions of the crab transferred via the gill removing portion 30, The cutter of the first embodiment is disposed.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .
