BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting apparatus, and more particularly, to an automated cutting apparatus capable of cutting cleanly regardless of a hard material or a soft material.

Cutting means cutting a material into a plurality of pieces. In order to perform a cutting operation, a cutting device by pressing the blade, a cutting device by cutting or grinding, a reciprocating motion such as a saw And the like are used. These cutting devices may be limited in use depending on the material to be cut. In particular, for devices that automate the feeding and cutting processes of materials, appropriate cutting devices should be used in view of the characteristics of the material.

Generally, a cutting apparatus by cutting or grinding is used for cutting a metal having a hard and thick thickness over a predetermined size, and a cutting apparatus by pressing the blade is used for cutting a thin metal plate or a non- It is mainly used. As described above, the cutting apparatuses use different methods depending on the material to be cut.

Particularly, when cutting a material such as food, there is a problem that it is difficult to cut cleanly by using a generally known cutting device. For example, in the case of kimbap or sundae, the outer surface of the soft material is surrounded by a film (steaming or intestine) having a certain strength, so that a cutting device by pressing the blade is used or a cutting blade is rotated Inappropriate. Such kimbap or sundae can be cut cleanly by cutting one by one with a knife.

In addition, it has been necessary to cut a large amount of foods having different intensities, such as rice cakes, radishes, cucumbers, etc., as well as foods having different intensities of the inside and the inside, such as kimbap or sundae. However, Could not be cut.

Conventionally, as disclosed in Korean Patent No. 10-0609435, there has been a device for cutting a Kimbap using a reciprocating blade. In the conventional cutting device, the knife is arranged to be inclined so as to cut the kimbap. However, since the knife is moved in parallel in the upward and downward directions in an oblique form, the knife is moved in the vertical direction Subsequently, the effect of actually cutting the rice was very limited.

Therefore, it is possible to cut cleanly regardless of hard or soft materials, and it is necessary to provide a more advanced cutting device capable of automatically cutting large quantities of food such as kimbap or sundae, such as by hand cutting by hand.

Like reference numerals refer to like elements throughout the specification.

Hereinafter, a cutting apparatus according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7. FIG.

FIG. 1 is a perspective view of a cutting apparatus according to an embodiment of the present invention, and FIG. 2 is a schematic sectional view of the cutting apparatus of FIG.

The cutting apparatus 1 according to the embodiment of the present invention is an apparatus for cutting a large amount of a subject M to be cut, such as food, while maintaining the original shape. Particularly, both the hard material and the soft material can be cut, and the object M to be cut, which is wrapped like a film on the outer surface, can be cut while maintaining the original shape. That is, the cutting apparatus 1 according to an embodiment of the present invention can cut a large quantity in the same manner as that for cutting the object M having various strength, viscosity, and elasticity such as rice cakes, . Hereinafter, the present invention will be described in detail with reference to the drawings.

1 and 2, a cutting apparatus 1 according to an embodiment of the present invention includes a frame 10, a container member 300, a conveying member 100, a driving unit 200, a cutting member 400, And includes a vibration member 500. The cutting apparatus 1 feeds the object to be cut M accommodated in the container member 300 to the cutting member 400 which reciprocates and cuts uniformly.

The frame 10 forms the skeleton of the cutting device 1 to support and protect other configurations. Particularly, the gap between the transfer member 100 and the cutting member 400 is held constant. Such a frame 10 may be formed with a rolling member 20 such as a wheel to facilitate transportation.

The conveying member 100 moves the container member 300 containing the object to be cut M toward the cutting member 400 and includes the belt member 110 and the rotary member 120.

The belt member 110 forms an endless track and is engaged with one side of the container member 300 and moves along an endless track. The belt members 110 are coupled to both sides of one side of the container member 300, respectively. However, the present invention is not limited thereto, and one or a plurality of the container members 300 may be combined according to the shape or size of the container member 300. The belt member 110 forms an endless track and may have various shapes and materials. For example, a belt having a chain or belt structure may be used.

The rotating member 120 includes a rotating shaft 121 and a rotating gear 123 and transmits power for rotating the belt member 110 in contact with the inside of the belt member 110. A plurality of rotary members 120 are provided to be positioned at a point where the belt member 110 is bent so that the belt member 110 can rotate smoothly.

Referring to FIG. 2, the rotating member 120 includes a first rotating member 120a, a second rotating member 120b, and a third rotating member 120c. The rotary member 120 allows the belt member 110 to move along three sides and one side of the three sides of the belt member 110 is cut by the cutting member 400 Process can be formed. In other words, any one of the three surfaces of the belt member 110 can be moved in a direction in which the interval gradually becomes narrower at an acute angle with the cutting edge 410. Thus, the rotary member 120 serves to guide the belt member 110 to be transported toward the cutting edge 410 in a required direction. Therefore, the number of the rotating members 120 and the number of the surfaces formed by the belt member 110 are not limited to the rounded triangular shape as shown in FIG. For example, when it is necessary to cut the object M in a very hard or very fragile manner so as to increase the cutting time, the number and position of the rotary member 120 are suitably arranged, The contact time of the object M to be cut can be increased.

The first rotating member 120a includes a first rotating shaft 121a and a first rotating gear 123a and the second rotating member 120b includes a second rotating shaft 121b and a second rotating gear 123b And the third rotating member 120c includes a third rotating shaft 121c and a third rotating gear 123c.

The first, second and third rotary gears 123a, 123b and 123c connect the first, second and third rotary shafts 121a, 121b and 121c to the belt member 110. [ The first, second, and third rotary gears 123a, 123b, and 123c may be formed variously according to the shape of the belt member 110. [ For example, as shown in FIG. 2, when the belt member 110 is a chain belt, sprockets may be used for the first, second, and third rotary gears 123a, 123b, and 123c. However, the first, second, and third rotary gears 123a, 123b, and 123c are not limited thereto, and gears having various structures that can be frictionally engaged with the belt member 110 may be used.

The driving unit 200 drives the conveying member 100 and includes a driving motor 210, a driving shaft 220, a driving gear 230, and a driving belt 240. That is, the power generated by the driving motor 210 is transmitted to one of the rotating gears 123 of the rotating member 120 through the driving shaft 220, the driving gear 230, and the driving belt 240, , Thereby driving the conveying member 100. [ The driving motor 210 is not limited to transmitting power through the driving shaft 220, the driving gear 230, and the driving belt 240, and may be connected to one rotating gear 123 of the rotating member 120 It can also be connected directly to deliver power.

The container member 300 accommodates the object to be cut M and is coupled to one side of the conveying member 100 and moves in a direction in which the belt member 110 of the conveying member 100 moves. A plurality of the container members 300 are provided and are aligned in a line in the longitudinal direction (conveying direction) of the belt member 110. In particular, the container member 300 may be aligned in a line across the length of the belt member 110. However, the present invention is not limited to this, and one or more of the container members 300 to be coupled to only a part of the belt member 110 may be provided. In addition, the container member 300 may be integrally coupled with the belt member 110, or may be detachably coupled.

Fig. 3 is a perspective view of a container member of the cutting apparatus of Fig. 1, and Fig. 4 is a cross-sectional view of the container member of Fig. 3 taken along line A-A '.

3 to 5, the container unit 300 includes a container member 300, which is disposed in a direction perpendicular to the conveying direction of the belt member 110 so as to receive and support a long object M to be cut in one direction, such as a rice cake, And has a long elongated shape. However, the present invention is not limited thereto, and the container member 300 may be provided in various shapes according to the object to be cut M.

The container member 300 has a side space 310 for supporting the side of the object to be cut M and a lower portion for supporting the bottom of the object to be cut M And a bottom member 320. The side member 310 and the bottom member 320 may be integrally formed, and may be formed and coupled to each other. In addition, the side member 310 and the bottom member 320 may be formed of different materials. In particular, the lower surface member 320 may be formed of a rigid material so that the cutting object M is not pushed when the cutting edge 410 of the cutting member 400 cuts the object M to be cut.

The container member 300 is formed with cutting grooves 312 and 322 at positions where the cutting edges 410 pass so that the cutting edges 410 of the cutting member 400 can pass therethrough. The cutting grooves 312 and 322 may be formed by cutting at least a part of the side member 310 and the bottom member 320. The cutting grooves 312 and 322 are formed in the container member 300 in accordance with the size and direction in which the object to be cut M is to be cut. For example, as shown in the figure, when it is desired to cut a long cylindrical cut object M such as a sundae or a glaze cake to a predetermined size in the longitudinal direction, a plurality of cutting grooves 312, 322 Is formed uniformly. The width of each of the cutting grooves 312 and 322 may be greater than the thickness of the cutting edge 410 so that the cutting edge 410 of the cutting member 400 can pass through. The depth of each of the cutting grooves 312 and 322 may be formed according to a depth at which the cutting object M is to be cut. For example, if it is desired to completely cut the object M to be cut, the cut grooves 312 and 322 may be formed at a height greater than the height of the object M to be cut. However, if the cutting object M is to be cut completely, the cutting grooves 312 and 322 are formed to a desired depth. In such a case, the cutting groove 322 may not be formed in the lower surface member 320.

Referring to FIG. 4, the bottom member 320 may be formed with a fitting groove 324 recessed in a bottom shape of the object M so that the object M is not shaken or dropped during transportation. That is, in the case of a long cylindrical object M to be cut, such as a sundae or a karaya cake, a semicylindrical fitting groove 324 may be formed in the bottom member 320.

Referring to FIGS. 4 and 5, the container member 300 can be coupled to the lower surface of the container member 300 with a center weight 330 for holding the center of gravity so as to prevent the container member 300 from shaking during movement. Particularly, when the container member 300 is changed in the moving direction or moved to the lower position, the container member 300 is shaken. A coupling groove 332 is formed on the lower surface of the container member 300 so that the center weight 330 and the container member 300 can be coupled by a fastening bolt.

Fig. 6 is a side view of the cutting apparatus of Fig. 1, and Fig. 7 is an enlarged view of Fig.

2, 6 and 7, the cutting member 400 is movably coupled to the frame 10 adjacent to one side end of the conveying member 100. As shown in Fig. The cutting member 400 includes a cutting edge 410, an upper bar 420, a lower bar 430, a connecting bar 440, a guide bar 460, a first elastic member 450, a second elastic member 470 ).

The cutting edge 410 includes at least one in consideration of the size and the number of cuts of the object M to be cut. That is, the number and position of the cutting edges 410 are determined according to the position and size of the cutting target M to be cut, such as the cutting groove of the container member 300. The cutting blade 410 is provided in a number corresponding to the cutting groove of the container member 300. [ The plurality of cutting edges 410 are arranged in parallel corresponding to the cut grooves of the container member 300.

The cutting edge 410 is disposed such that an extension line of the feeding direction of the feeding member 100 and an extension line of the cutting member 400 in the reciprocating direction cross each other at an acute angle. That is, the feed member 100 and the cutting edge 410 are disposed such that the distance between the feed member 100 and the cutting edge 410 is gradually narrowed along the feed direction of the feed member 100.

In other words, the conveying member 100 is configured such that the first rotation axis 121a, the distance between the center of the cutting blade 410 and the axis being spaced apart from the center of the axis by a first distance, And a second rotation axis 121b disposed in parallel with the first rotation axis 121a is disposed in parallel with the first rotation axis 121a and the second rotation axis 121b and is disposed in parallel with the first rotation axis 121a in the horizontal direction The transfer member 100 and the cutting blade 410 which move from the first rotation axis 121a to the second rotation axis 121b with the second gap being narrower than the first gap, Can be gradually narrowed.

Further, the cutting blade 410 can be arranged so as to be inclined toward the feeding member 100 with respect to the vertical direction while the feeding member 100 is arranged as described above. The cutting blade 410 moves along the tilted direction and cuts the object M to be cut.

The cutting member 400 includes an upper bar 420 arranged in a direction perpendicular to the cutting edge 410 and connected to one end of the cutting edge 410 and an upper bar 420 arranged in parallel with the upper bar 420, And a connection bar 440 connecting between the upper bar 420 and the lower bar 430. [

The cutting edge 410 is provided between the upper bar 420 and the lower bar 430 and is coupled to penetrate at least one of the upper bar 420 and the lower bar 430.

The cutting blade 410 can be loosened by the reciprocating movement and the first elastic member 450 is interposed between the end of the cutting edge 410 and the upper bar 420 or the lower bar 430 The tension of the cutting edge 410 can be adjusted.

The cutting member 400 also includes a guide bar 460 connected between the upper bar 420 and the lower bar 430 and fixed to the frame 10. The impact applied to the cutting member 400 by the second elastic member 470 between the end portion of the guide bar 460 and the upper bar 420 or the lower bar 430 can be alleviated.

6 and 7, includes an oscillating member 500 coupled to the cutting member 400 and applying a vibration to reciprocate the cutting member 400 in the longitudinal direction of the cutting blade 410. As shown in FIG.

The vibration member 500 may be provided on a supporting member which is coupled to either the upper bar 420 or the lower bar 430 of the vibration member 500. When the vibration member 500 coupled to the supporting member generates vibration, the upper bar 420 or the lower bar 430 coupled with the supporting member vibrates according to the vibration direction, and accordingly, the cutting edge 410 also vibrates do.

The vibration member 500 may be an eccentric vibrator that generates vibration by the eccentric rotation body so as to vibrate reciprocally along the longitudinal direction of the cutting edge 410. However, it is not limited thereto.

When the vibrating member 500 vibrates the upper bar 420, the upper bar 420, the lower bar 430, the connecting bar 440 and the cutting blade 410 move along the guide bar 460, . The second elastic member 470 interposed between the end portion of the guide bar 460 and the upper bar 420 or the lower bar 430 may be a coil spring and includes an upper bar 420, 430, the connecting bar 460, and the cutting edge 410. [0054] As shown in FIG. That is, the cutting blade 410 can be reciprocated while maintaining an appropriate frequency such as a vibrator provided on the coil spring. Here, the guide bar 460 guides the cutting blade 410 to move in a predetermined direction. Therefore, the cutting edge 410 is repeatedly moved in a direction to cut the object M to be cut.

The cutting device 1 according to the present invention as described above is configured such that when the object M to be cut accommodated in the container member 300 is moved by the feed member 100, 410 are reciprocated by the oscillating member 500 to cut the object M to be cut.

The cut object M thus cut is discharged through an outlet 30 fixed to one side of the frame 10. The object M to be cut, which is discharged through the discharge port 30, can be maintained in a circular shape while being constantly cut.

An operation state in which the object to be cut M is cut by the cutting edge 410 is as follows.

8 to 10 are views for explaining the operation of the cutting apparatus according to the embodiment of the present invention.

Referring to FIG. 8, the object to be cut M is conveyed along the conveying member 100 toward the cutting member 400 by being contained in the container member 300. The conveying member 100 is refracted to have three surfaces, conveyed in the horizontal direction, refracted by the first rotating member 120a, and conveyed toward the cutting edge 410. [

As shown in Figs. 8 to 10, the cutting blade 410 reciprocates only in the longitudinal direction in which the blade keeps the tilted direction and the blade is directed. That is, the cutting edge 410 does not exert any pressure on the object M to be cut, but merely cuts the object M to be cut.

At this time, the conveying member 100 conveys the object to be cut M toward the cutting edge 410. As described above, the conveying member 100 conveys the object to be cut M so that the extension line of the conveying direction intersects the extension line of the cutting member 400 in the reciprocating direction at an acute angle with each other. That is, the cutting member 400 always reciprocates in the same direction, and the feeding member 100 gradually moves the cutting object M to the cutting member 400, thereby cutting. The conveying speed of the conveying member 100 can be variously adjusted according to the characteristics of the object M to be cut. For example, in the case where the object to be cut M is a hard material such as a bone, the conveying speed of the conveying member 100 can be remarkably reduced, and when the object to be cut M is relatively soft, Can be adjusted quickly. Further, when the object to be cut M is wrapped around the outer surface of the food such as kimbap or sundae, the speed can be relatively reduced so that the pressure is not transmitted in the vertical direction to the film such as the stomach or intestines.

As shown in FIG. 8, when the object to be cut M approaches at an angle while the cutting edge 410 is constantly reciprocating, the effect is almost the same as that of cutting the object by hand .

8 to 10, the time and area of contact with the cutting edge 410 increases while the object to be cut M approaches and passes obliquely to the cutting edge 410. That is, the cutting edge 410 gradually approaches and gradually approaches the object M to be cut, so that damage to the object M to be cut can be minimized, not by a method of applying pressure to the object M to be cut at once . Therefore, even after the cutting object M, such as a kimbap or a sash, is cut, the original shape can be maintained.

9 and 10, the conveying member 100 discharges the cut object obliquely while discharging it while maintaining the original shape. The conveying member 100 includes the belt member 110 of the endless track type and is operated continuously.

Thus, it can be seen that the cutting apparatus 1 according to the embodiment of the present invention is substantially the same principle as that of placing the food on the cutting board in real life, and the effect is substantially the same. Thus, even when a food of a hard material or a food of a material having a different strength is attached, it can be cut while maintaining the original shape of the food.

The cutting device 1 according to the embodiment of the present invention is designed to cut food having a special structure such as sundae or kimbap. However, the cutting device 1 is not necessarily limited to cutting food, and may be utilized for cutting various materials for industry It will be possible.

In addition, the cutting apparatus 1 according to the embodiment of the present invention shows that the cutting member 400 is disposed on the side of the conveying member 100, but the present invention is not limited thereto. That is, on the upper side of the conveying member 100

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, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
