Description

Automatic peeling device

The present invention relates to an automatic peeling device, and more particularly, to an automatic peeling device for peeling vegetables such as radishes.

Bulbous is a crop that forms a spherical storage organ in the ground. There are various kinds of radish, carrot, garlic, onion, etc. Among them, radish is one of the most used vegetables in Korea, and is used in various recipes in various menus.

Radish needs to be processed before going into cooking. Since it is a root, the soil on the surface must be removed and the skin must be peeled off.

To this end, in the prior art, after a washing process, a person directly held the blade in his hand to cut the radish. At this time, it was possible to rotate the radish, and it was also possible to cut the radish by directly acting on the surface of the rotating radish by holding the blade firmly.

However, this method is very labor intensive. It goes against the trend of various devices becoming automated and artificial intelligence. It is disadvantageous in terms of time and cost, and there is also a risk of a safety accident in which the blade is thrown out by the rotating body if the blade is lost in the hand.

In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2012-0024068 shows an automatic skin peeling device. It is to peel the skin of radish automatically by rotating and contacting the blade with constant pressure on the outer surface of the rotating radish fixed on the vertical axis of rotation.

The prior patent also shows a technique for allowing the blade to act on a non-surface with a constant pressure using a spring. This is because the shape and size of radishes vary, so it is necessary to peel the radish to a certain thickness.

However, when operating the actual device, it is not easy to peel off the skin with a certain thickness, contrary to expectations.

Aside from this, the shape of each radish is different, so there are many cases where there are shaded areas where peeling is not done.

A device capable of faster and more consistent peeling is required, and the existing techniques including the prior patent do not provide a technique that satisfies the consistency of peeling while being quick at the same time.

The inventor of the present invention has completed the present invention after long research and trial and error in order to solve these problems.

An embodiment of the present invention provides an automatic peeling device of a novel structure that can even and quickly peel the surface of an object.

On the other hand, other objects not specified in the present invention will be additionally considered within the range that can be easily inferred from the following detailed description and effects thereof.

An automatic skin peeling device according to an embodiment of the present invention includes a peeling means for peeling an object, wherein the peeling means includes: a first peeling skin for peeling off the object by acting on a portion larger than a set size; And it may include a second peeling skin for peeling the object by acting on a smaller portion than the set size.

The peeling means may be transferred from the first position to the second position and peel the object rotatably fixed to the peeling position.

The first peeling skin may include a plurality of rotating blades that rotate in place, and the second peeling skin may include one or more fixed blades that can be tilted and rotated in close contact with the surface of the object.

It may further include; a transfer unit for transferring the object to the peeling position.

In the following, the most preferred embodiment of the present invention is described. In the drawings, the thickness and the interval are expressed for convenience of description, and may be exaggerated compared to the actual physical thickness. In describing the present invention, well-known components that are not related to the gist of the present invention may be omitted. In adding reference numbers to the components of each drawing, it should be noted that only the same components are given the same number as possible even though they are indicated on different drawings.

1 shows a perspective view of an automatic skin peeling device 100 according to an embodiment of the present invention.

Figure 1a is the state before the skinned object 10 enters the peeling position (P) of the automatic skinning device 100, Figure 1b is the state after the skinned object is entered into the skinning position (P) by the transfer unit 120 And, Figure 1c shows a state in which the skinned object is fixed in the peeling position (P) by the holding part 130.

As shown in FIGS. 1A to 1C , the automatic skinning device 100 includes a skinning means 110 for peeling a skinned object, a transfer unit 120 for transferring the skinned object to a skinning position, and a rotatably fixing the skinned object It includes a holding unit 130 and a tray unit 140 for the recovery of the skinned object and the skin residue.

The skinned object 10 enters and is fixed to the skinned position (P). 1a to 1c show a process in which the object to be peeled is fixed by entering the location to be peeled in sequence.

The peeling object 10 rotatably fixed to the peeling position P is peeled while the peeling means 110 is transferred from the first position Pa to the second position Pb (D1 direction, see FIG. 1C ).

A rail 102 may be provided on the automatic skinning device for the transfer of the skinning means. The rail 102 extends in the D1 (or D2) direction.

For peeling, the peeling means 110 includes a first peeling skin 112 and a second peeling skin 114 . A more detailed description will be given later with reference to FIG. 2 .

The transfer unit 120 is involved in the entry of the skinned object to the skinned position, and the holding unit 130 is engaged in fixing at the skinned position.

The transfer unit 120 is provided in the automatic peeling device to enable upward and downward movement. Fig. 1a shows the original position of the transfer unit, Fig. 1b shows the upwardly moved state from the original position, and Fig. 1c shows the downwardly moved state back to the original position.

The skinned object placed on the conveying unit rises with the upward movement of the conveying unit and enters the peeling position (P).

The transfer unit may include tongs provided symmetrically left and right as shown in the drawing so that the skinned object does not escape to the outside during the upward movement. The tongs have a structure that can pick up the skinned object placed on the transfer unit.

The holding unit 130 rotatably fixes the skinned object 10 that has entered the skinned position (P) in place.

Both ends of the object to be peeled are rotatably fixed by holding units. To this end, the holding unit 130 includes a first holding unit 132 and a second holding unit 134 .

The first holding part 132 presses one end of the object to be peeled, and the second holding part 134 presses the other end of the object to be peeled. In the present invention, an embodiment in which the skinned object is firmly fixed between the holding parts by pushing one end of the skinned object that has entered the peeling position toward the second holding portion provided with the first holding part in a flexible structure (D2 direction, see FIG. 1c) Although mainly described, the present invention is not limited thereto.

The holding parts are provided in a structure capable of rotating the skinned object fixed therebetween so that the skinned object is fixed in the skinning position and rotated in place at the same time. The direction of rotation is referred to by reference numeral R in the drawings. A motor and bearing structures for rotation in the R direction may be provided.

As will be described later, when the object to be peeled is fixed at the location to be peeled, the peeling means is transferred from the first position (Pa) to the second position (Pb) while peeling the object rotating in the R direction.

The tray unit 140 is provided in a structure capable of entering under the peeling position and retracting from the peeling position to the original position. 1A and 1B show the original position of the tray part, and FIG. 1C shows the state retracted from the original position, respectively.

Rails 104 may be provided on the automatic skinning device for advancing and retracting the tray portion. The rail 104 may extend in a direction orthogonal to the D1 (or D2) direction.

As shown in FIGS. 1A to 1C , the transfer unit 120 and the tray unit 140 for entering the skinned object 10 to the skinning position P may alternately enter under the skinning position. For example, when the transfer unit 120 moves upward to transport the object to be peeled to the peeling position and then descends to exit, the tray unit 140 moves forward to the spot to recover the peeled object and the peeling residues. (see FIGS. 1B and 1C). The tray unit collects the objects and residues falling by gravity under the skinning position, and ends the recovery by retreating back to the original position (see FIG. 1A ). And when the skinned object is placed again on the empty seat of the transfer unit in the original position, the above process may be repeated.

The time point at which the holding part fixes the skinned object is immediately after completion of the upward movement of the transfer part. That is, immediately after the transfer unit moves upward and enters the skinned object into the skinning position, the holding unit fixes the skinned object at the skinning position. When the fixing by the holding part is completed, the conveying part moves downward to the original position.

Hereinafter, with reference to FIGS. 2 to 3 , a process of peeling an object to be peeled at a peeling position will be described in detail.

Figure 2 is a view showing in detail the structure of the peeling means according to an embodiment of the present invention.

Fig. 2a shows its front view and Fig. 2b shows its side view, respectively.

As shown in FIGS. 2A and 2B , the skinning means 110 rotates in place and directly acts on the surface of the first skinned skin 112 for peeling the skinned object and the second foil for peeling the skinned object by acting directly on the surface of the skinned object. skin 114 .

The first peeled skin and the second peeled skin have different methods of peeling. The first peeling skin is a method of grinding the surface of the object to be peeled to a certain depth and peeling it, and the second peeling skin is a method of cutting the surface of the object to be peeled (think of a potato knife as if cutting the surface of a fruit with excessive use). .

The first skinned skin 112 includes a body 1122 including a plurality of blades rotating in place, and a plurality of rotating blades 1124 respectively mounted on the plurality of blades. The number of blades and the number of rotating blades may match.

A first foil skin is referred to in a direction to rotate in place, with the drawing R _B. As the first foil skin is rotated at a high speed by R _B direction, this first foil peeling means (110) that is provided with the skin is transferred to the D1 direction, as a result, the transferred to a night skin D1 direction peel object peel off

At this time, as described above, since the skinned object rotates in the R direction in place, all surfaces through which the first skinned skin passes are peeled off.

The second thinning skin 114 includes an arm portion 1142 that can be tilted and rotatable in close contact along the surface of the object, and two fixed blades 1144 and 1146 mounted on the arm portion.

The arm unit 1142 includes a structure capable of sliding along the rail 102 at one end. It includes a structure for mounting the fixed blades on the other end.

The fixed blades 1144 and 1146 have a shape like a round blade with a flat bottom, bolted to the arm portion.

In the present invention, an exemplary embodiment having two fixed blades is mainly examined, but the present invention is not limited to the number. For example, only one fixed blade may be mounted on the arm portion, and a larger number of blades may be mounted as needed.

As shown in the figure, when two or more fixed blades are mounted, they are mounted vertically spaced apart from each other, and at this time, the efficiency of peeling can be greatly increased by varying the angle at which they are mounted. This is so that the angle at which the peeling surface of the rotating peeling object enters with respect to each of the fixed blades becomes the sharpest. That is, the fixed blade 1144 mounted on the relatively is mounted at an angle such that the angle at which the object to be peeled rotates and enters at its peeling position becomes the sharpest, and as shown in FIG. 2B , generally with respect to the arm portion It can be mounted at an angle of 25° to 50°. The fixed blade 1146 mounted below is mounted at an angle such that the angle at which the object to be peeled enters by sea electrolysis at its peeling position becomes the sharpest, and as shown in FIG. 2B, it is generally inclined with respect to the arm part Can be mounted parallel without load. Since the object to be peeled is cylindrical, it is mounted at a slightly inclined angle with respect to the tangent plane from the center so that the angle of entry of the rotating peeling surface is the sharpest for each blade.

In order for these fixed blades to directly contact and act on the skinning surface (so that the surface of the skinned object can be shaved by being in close contact with the skin as much as possible), the arm unit is provided to enable vertical and horizontal tilting motions.

A direction in which the arm portion 1142 is inclined up and down is referred to as _{R T1 in the drawing.} The direction in which the arm part is inclined up and down is a direction in which the fixed blades mounted on the arm part move away from or approach the skinned object. It's like a seesaw movement. Accordingly, the fixed blades 1244 and 1246 can be stably in close contact with the surface of the skinned object as the arm portion is tilted up and down according to the curvature of the skinned object.

A direction in which the arm portion 1142 is inclined to the left and right is referred to as _{R T2 in the drawing.} The direction in which the arm part is inclined to the left and right is the same direction in which the tangent plane of the fixed blades mounted on the arm part with respect to the object to be peeled is inclined to the left and right. It's like a tilt motion. Accordingly, the wide bottom surfaces of the fixed blades 1244 and 1246 may be in close contact with the surface of the skinned object by inclining the arm part to the left and right according to the curvature of the object to be peeled.

Vegetables such as radishes are not ideal cylindrical and have a rough outer surface, so the efficiency of peeling can be improved by making the fixed blades capable of rotating in the vertical direction (seesaw motion) and rotating in the left and right direction (tilt motion) as described above. can

On the other hand, an elastic member (not shown) serving to press the fixed blades toward the object to be peeled may be further provided in the peeling means so as to be in close contact during the peeling process. The pressing direction is referred to as D3 in the drawing. For example, an elastic member such as a spring has one end connected to a fixed end and the other end connected to a free end (referred to as B in the drawing) so that the fixed blades are constantly pressed in the direction toward the skinned object.

Let's look at the peeling process through the above-described peeling means in more detail.

3 is a view showing in detail a skin peeling process by a skin peeling means according to an embodiment of the present invention over time.

As shown in Figure 3a, the peeling begins, and the peeling is finished as shown in Figure 3c through Figure 3b. Each corresponds to a top view of the automatic peeling device.

First, referring to FIG. 3A , the skinned object 10 rotates in the R direction in place with the left and right sides fixed by the holding parts 132 and 134 . Its center of rotation is referred to as A1 in the drawings.

The skinning means peels the skinned object while sliding along the rail 102 in the D1 direction as described above.

Specifically, the rotation in the rotating days are R _B direction of the first foil skin 112 and pass away the position (r1 + r2), some distance away from the rotational center portion holding (A1) (i.e., the center of rotation of the peeling object) Thus, the peeled object is peeled to have a predetermined radius (r2).

The translational trajectory of the first peeled skin is consistent throughout the entire peeling process. Reference is made to A2 in the drawings. It is well seen that the translational movement trajectory of the first peeled skin is consistent over FIGS. 3A to 3C .

The predetermined radius r2 of the skinned object may be a value set by the user.

As an example, the user may set r2 to 5 cm, and in this case, the peeling means may position the first peeling skin at a position that allows the first peeling skin to peel the areas larger than 5 cm in a radius of the skinned object . That is, the distance from A1 to A2 may be adjusted according to the set predetermined radius r2. On the other hand, the r1 value corresponds to a fixed value as a value corresponding to the rotation radius of the first peeled skin.

Users who want to peel with a smaller diameter can set r2 to be small, and users who want to peel with a larger diameter can set r2 to be large. r2 is generally determined according to the size of the object to be peeled. For example, when peeling a large-sized radish, r2 may be set to be large, and when peeling a small-sized radish, r2 may be set to be small.

Of course, if a separate size determination device is provided in the automatic skin peeling device according to an embodiment of the present invention, the r2 value may be set by automatically determining the size of the skinned object without the user setting one by one.

Unlike the coherent trajectory of the first skin, the second skin 114 is variable in position from A1 along the surface of the skinned object. This is because, as described above with reference to FIG. 2, the second thinning skin is provided to enable _{up-and-down tilting motion (tilting motion in the R T1 direction).} If FIG. 3A shows a state in close contact in the D3 direction, FIG. 3B shows a state that is less closely adhered than FIG. 3A, and FIG. 3C shows a state that is more closely adhered than FIG. 3A, respectively.

Therefore, the second peeling skin 114 peels off a portion smaller than the predetermined radius r2 set by the user.

In Fig. 3a, the introduction part (such as the head of a radish) of the dermabrasion object smaller than r2 is peeled, in Fig. 3b the middle part of the dermabrasion object smaller than r2 is peeled, and in Fig. 3c the dermabrasion object smaller than r2 It is well seen that the tail part of the squash (like the root part of radish) is peeled off. In the figure, the portion peeled off by the first skinned skin is referred to as PD1, and the portion peeled off by the second skinned skin is referred to as PD2.

In this way, the second skinned skin may be peeled off to a portion that the first skinned skin could not peel.

In addition, since the second skinned skin is provided so that a left and right tilting motion (a tilting motion in the R _T2 direction) is possible, regardless of the inclination of the introduction portion of the skinned object or the inclination of the tail portion of the skinned object, the It adheres to the surface and can peel off the object. In FIG. 3A , it is well seen that the second skinned skin is tilted clockwise and adhered to the peeling surface, and in FIG. 3C, the second peeled skin is tilted counterclockwise and closely adhered to the skinned surface.

In this way, when the skinning means peels off an object to be peeled, the first peeling skin peels a portion larger than the set size r2, and the second peeling skin peels a portion smaller than the set size r2, so that the uneven surface It is possible to peel the skinned object with a consistent size desired by the user, without a shadow area that cannot be peeled off. In addition, a rapid peeling operation is possible through the high-speed rotating peeling object, the first peeling skin rotating at a high speed corresponding thereto, and the second peeling skin closely peeling in response to the curvature of the skinned object during sliding movement of the skinning means. .

In FIG. 3 , only the fixed blade is shown without an arm part on behalf of the second thinning skin, but it is only for convenience of description, and the present invention is not limited thereto.

On the other hand, the amount of peeling is determined based on the rotation center (A1) of the holding part, and accurately positioning the peeling object at the peeling position plays an important role in the above-described processes. That is, since the bumpy amorphous peeling object such as radish is peeled to have a predetermined radius r2 spaced a certain distance from its rotation center A1, the center must match when the peeling object is held by the holding part (holding part). The center of rotation (R) and the center of gravity (or geometric center) (C) of the skinned object should approximately coincide).

To this end, the transfer unit 120 includes a base portion 122 for initial seating of the skinned object and a plurality of gripper pairs 124a and 124b, 126a and 126b, 128a and 128b for aligning the skinned object to the correct position Pi. may include

Each of the plurality of gripper pairs 124a and 124b, 126a and 126b, 128a and 128b (see FIG. 1A ) includes grippers disposed to face each other. The first pair of grippers includes a gripper 124a and a gripper 124b facing each other. The second pair of grippers comprises a gripper 126a and a gripper 126b facing each other. The third pair of grippers comprises a gripper 128a and a gripper 128b facing each other. Although three gripper pairs are shown in the present invention, a larger number of gripper pairs may be provided as needed. Since each of the grippers 124a, 124b, 126a, 126b, 128a, and 128b has the same structure, the second gripper pair 126a, 126b disposed in the middle is viewed as a center.

4 is a diagram illustrating a detailed structure of a base portion and a gripper pair of a transfer unit according to an embodiment of the present invention. Fig. 4A shows a state before the object to be peeled is aligned by the pair of grippers, and Fig. 4B shows a state after the object to be peeled is aligned by the pair of grippers, respectively.

First, referring to FIG. 4A , the object to be peeled 10 is placed in an arbitrary position on the base portion 122 before alignment. What is necessary is just to assume the case where the skinned object is placed in the automatic skinning device shown in FIG. 1A.

As shown in the drawing, each of the grippers 126a and 126b includes a lower inclined portion Ga, an upper inclined portion Gb, and a bent portion Gc therebetween.

Next, referring to FIG. 4B , the gripper pairs 126a and 126b facing each other move in a direction toward each other for alignment. It can move along the rail 106 . The direction of movement of the gripper pair is indicated by arrows in the figure.

As the pair of grippers get closer to each other, the lower inclined portion Ga pushes the object to be peeled up primarily, and the upper inclined portion Gb secondly pushes the object to be peeled down. Accordingly, the dermabrasion object may be aligned to the position Pi defined by both curved portions Gc.

Note that in the alignment process, the target to be peeled has moved upward by h (see FIG. 4B ) from the base portion 122 on which it was initially seated. Note also that since the pair of grippers move by the same amount on both sides of the object to be peeled, the object to be peeled also moves in the left and right direction so that its center is placed at the center of the object to be peeled.

In FIG. 4 , an embodiment in which the second gripper pair is aligned is mainly described, but the present invention is not limited thereto, and the first gripper pair or the third gripper pair may also perform the same operation as described above. If the size of the object to be peeled is small, only the first and second pairs of grippers are sufficient to operate, and if the size of the object to be peeled is large, all gripper pairs up to the third pair of grippers are operated to increase the efficiency of aligning them in place. can be raised

In this way, the skinned object 10 may be aligned in the original position Pi by the transfer unit 120 . And when it is transferred to the holding unit 130 in a state aligned in place, the skinned object is naturally arranged so that the center is aligned when held by the holding unit. That is, the rotation center (R) of the holding part and the center of gravity (or the geometric center (C) of the skinned object are substantially coincident. As a result, even if any amorphous skinned object is transferred to the skinning position, the transfer unit according to the embodiment of the present invention center can be adjusted automatically.

As described above, according to the automatic peeling device according to an embodiment of the present invention, it is possible to peel the surface of the object evenly and quickly. In addition, the surface of the object can be easily peeled to a desired size. In addition, since the diameter of the object after peeling can be obtained uniformly to the size desired by the user, there is an advantage that can facilitate the subsequent processing of the object such as radish to be easy to eat.

Although the technical spirit of the present invention has been specifically recorded according to the above preferred embodiments, it should be noted that the above-described embodiments are for explanation and not limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical spirit of the present invention.
