DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

In describing the embodiments of the present invention, it is to be noted that components having the same function are denoted by the same names and numerals, but are substantially not identical to those of the prior art.

Furthermore, the terms used in the embodiments of the present invention are used only to describe specific embodiments, and are not intended to limit the present invention. The singular expressions include plural expressions unless the context clearly dictates otherwise.

Furthermore, in the embodiments of the present invention, terms such as "comprises" or "having ", etc. are intended to specify the presence of stated features, integers, steps, operations, elements, parts, or combinations thereof, Steps, operations, elements, components, or combinations of elements, numbers, steps, operations, components, parts, or combinations thereof.

The nick braking apparatus of the present invention will be described with reference to Figs. 2 and 3. Fig. 2 and 3 are a perspective view and a side view of the nick braking apparatus of the present invention.

The nick braking apparatus of the present invention includes a frame, a conveying unit, a pressing unit 100, and a supporting unit 200.

The frame forms the body of the nick braking device and may be in the form of a conventional nick braking device. The frame may include a driving unit and a control unit.

At this time, the driving unit provides a configuration necessary for driving, such as driving the transfer unit, the pressing unit 100, and the supporting unit 200 to be described later. The control unit may control the apparatus so as to cut the portion of the nick 50 formed on the cardboard 20 in association with rotation of the pressing unit 100 or the supporting unit 200.

The transfer unit is provided in the frame to transfer the cardboard 20. The transfer unit is provided with a conveyor belt and a roller unit, and can transfer the cardboard 20. The shape and the configuration of the cartridge 50 do not matter if the carton 20 on which the nick 50 is formed is supplied to the pressing unit 100 and the supporting unit 200 so that the nick 50 can be broken and discharged.

The pressing unit 100 will be described with reference to Fig. 4 is a view showing the pressing unit 100 of the nick braking device of the present invention.

The pressurizing unit 100 may include a first shaft 120, a first base portion 160, and a pressurizing portion 140 in a configuration for breaking the nick 50 together with the support unit 200. [

The first shaft 120 may be provided in the frame and may have a shape of a cylinder having an internal hollow space for rotation.

The first base portion 160 may be coupled to the first shaft 120 and rotated together by rotation of the first shaft 120. In this case, the first base portion 160 may be provided in a wooden shape surrounding the first shaft 120.

Since the first base portion 120 is provided in the shape of a tree, the user can easily attach / detach the pressing portion 140, which will be described later, to a necessary portion of the first base portion 160. In addition, the wood is cheaper than other materials in production, so it can be economically advantageous.

The pressing portion 140 may be coupled to the first base portion 160 or may be directly coupled to the first shaft 120 as described above. Accordingly, the pressing portion 140 is coupled to the outer portion of the first base portion 160 or the first shaft 120 and is rotated by the rotation of the first shaft 120.

When the pressing portion 140 is coupled to the first base portion 160, there is only a difference in the effect as described above, and there is no significant difference in the effect of breaking the nick 50. Therefore, for convenience of explanation, a case where the pressing portion 140 is coupled to the first base 160 provided on the first shaft 120 will be described below.

The pressing portion 140 can be cut by applying pressure to the nick 50 portion of the cardboard 20 supplied by the conveying unit while rotating.

At this time, since the portion where the nick 50 is formed may vary, the pressing portion 140 may be coupled to the first base portion 160 correspondingly. This makes it possible to install the nick breaker quickly by attaching the pressing portion 140 to the first base portion 160 corresponding to the portion where the nick 50 is required to be broken. Thus, the present invention has advantages over conventional nick braking devices in which the cutting device must be aligned at the point where the nick 50 needs to be broken.

In general, considering the purpose of forming the nick 50, the nick 50 is not large in size or complex in shape, so that the pressing portion 140 does not necessarily need to be sharp or sharp. That is, if the nick 50 can be broken, the shape of the pressing portion 140 may be variously formed.

The first base portion 160 may include a friction portion 180. At this time, a part of the friction portion 180 may be in contact with the cardboard 20 to transfer the cardboard 20. That is, as shown in FIG. 3, the frictional portion 180 is provided so as to be in contact with the transported paperboard, so that the frictional portion 180 can perform the function of breaking and discharging the nick 50.

At this time, the friction part 180 may be provided to cover the whole of the first base part 160 except for the pressing part 140, or may be provided to partially surround the first base part 160.

Such a friction portion 180 has an advantage that the cardboard 20 can be transported even when the support unit 200 to be described later does not have a frictional force.

The support unit 200 will be described with reference to Figs. 5 and 9. Fig. 5 is a diagram of a support unit 200 including a second shaft. 6 is a view of the support unit 200 including the rail part 280. [

The support unit 200 may be located adjacent to the pressurization unit 100 and may include a second base portion 260 and a protrusion 240.

The support unit 200 is configured to break the nick 50 together with the pressing unit 100. [ That is, the pressing portion 140 of the pressing unit 100 and the protruding portion 240 of the supporting unit 200 interact with each other to break the nick 50.

That is, the pusher 140 breaks the nick 50 of the cardboard 20 while entering the space between the protrusions 240. At this time, the protrusion 240 supports the portion of the cardboard 20 around the nick 50, so that only the nick 50 formed on the cardboard 20 can be broken.

The second base portion 260 moves in conjunction with the second shaft 220 or the rail portion 280 to be described later. At this time, the movement of the second base unit 260 refers to all the movements in the transport direction of the rotating or cardboard.

5, the second base portion 260 may be coupled to the second shaft 220 to rotate in accordance with the rotation of the second shaft 220. As shown in FIG.

Alternatively, as shown in FIG. 9, the second base portion 260 may be coupled to the rail portion 280 so as to have a trajectory shape and function as a conveyor belt. When the support unit 200 is decorated in a track shape, the nick 50, which can be variously formed according to the size of the paperboard 20, etc., can be broken at one time.

At this time, the second shaft 220 rotates in a direction opposite to the rotation direction of the first shaft 120, and at this time, the shaft of the first shaft 120 is positioned above the shaft of the second shaft 220 The device can be configured.

As shown in FIG. 3, the first shaft 120 and the second shaft 220 rotate in opposite directions in accordance with the transport direction in which the cardboard 20 is inserted and discharged. Accordingly, the first shaft 120 and the second shaft 220 can also be transported along with the fracture of the nick 50.

The protrusion 240 may be formed so that a part of the second base 260 protrudes. That is, the protrusion 240 is formed in a concavo-convex shape and can support a part of the cardboard 20 to break the nick 50 together with the pressing portion 140.

It is preferable that the protruding portion 240 is a concavo-convex shape formed in the structure of the checkerboard as shown in the figure. If the protruding portion 240 can break the nick 50 by the pressing portion 140 and the protruding portion 240, And can be variously formed.

However, since the nick 50 is broken due to the interaction between the pressing part 140 and the protruding part 240, the relative sizes of the pressing part 140 and the protruding part 240 may be problematic.

3, the end portion of the pressing portion 140 when the rotating pressing portion 140 is located at the lowest position is a surface of the depressed portion between the protruding portions 240 of the supporting unit 200, It is preferable to be formed so as to be positioned between the surfaces of the first electrode layer 240 and the second electrode layer 240.

This is to prevent interference between the pressing unit 140 and the supporting unit 200 so as to prevent a part of the supporting unit 200 from being damaged by the pressing unit 140 and break the nick 50 properly .

3, the width of the pressing portion 140 may be shorter than the width of the depressed portion between the protrusions 240. As shown in FIG. However, the transverse lengths of the pressing portion 140 and the protruding portion 240 are not significantly affected by restoration of the protruding portion 240 to be described later.

Specifically, when the protruding portion 240 is pressed by the pressing portion 140, the protruding portion 240 may be restored to a state before being pressed. Therefore, the protrusion 240 may be made of a material having elasticity such as silicone or rubber. However, it is not a problem if the material of the protruding portion 240 has a restoring force to restore the state before the protruding portion 240 is pressed after the protruding portion 240 is pressed.

Accordingly, the second base portion 260 supports a portion of the cardboard 20 supplied by the transport unit while moving, and the protrusion 240 breaks the portion of the nick 50 together with the pressing portion 140.

The diameter of the second shaft 220 may be different from the diameter of the first shaft 120. Specifically, the diameter of the second shaft 220 may be smaller than the diameter of the first shaft 120.

In the conventional case, the cutting device coupled to the shaft provided above and below has to be precisely positioned at the nick portion, so that the shaft has to be formed in the same size.

However, in the case of the present invention, since the support portion can be formed to be restored, it is not subjected to the conventional limitations.

The diameter of the second shaft 220 is smaller than the diameter of the first shaft 120 so that the pressing portion 140 can be pressed against various portions of the protrusion 240 coupled to the second shaft 220. Therefore, in terms of durability, the upper and lower shafts are more advantageous than when they are formed to have the same size.

Also, since the second shaft 220 is small, the overall size and weight of the knocking braking device can be reduced, which is economical. In addition, since the transfer unit can be disposed close to the second shaft 220, it is possible to have a configuration favorable to the movement of the cardboard 20.

At this time, the rotating speed of the first shaft 120 may be the same as the rotating speed of the second shaft 220.

The first shaft 120 and the second shaft 220 rotate at the same speed so that the cardboard 20 can be naturally introduced into and discharged from the pressurizing unit 100 and the support unit 200. [

The adjustment of the optimum speed according to the difference in the diameters of the first shaft 120 and the second shaft 220 can be adjusted by a control unit provided in the frame.

The principle of breaking the nick 50 by the interaction of the pressing unit 100 and the supporting unit 200 of the nick braking apparatus of the present invention will be described with reference to Figs. 6 to 8 are views showing an embodiment of the nick braking apparatus of the present invention. Hereinafter, the position of the embodiment of the present invention is based on the side view of FIG.

6 shows a case where the depressed portion between the pressing portion 140, the nick 50 formed in the cardboard 20, and the protruding portion 240 is positioned in a straight line.

In this case, the pressing portion 140 presses the nick 50, and the protrusion 240 supports the periphery of the nick 50, so that the nick 50 is broken by the pressing portion 140.

7 shows a case where the pressing portion 140, the nick 50 formed on the cardboard 20, and the protruding portion 240a are located in a straight line.

In this case, the pressing portion 140 presses the nick 50 and receives the pressure by the pressing portion 140, and the protrusion 240a is lowered by the amount of the pressure to be received. After the nick 50 is broken And restored to its original state.

6 except for the protrusion 240a receiving the pressure of the pressing unit 140 supports the cardboard 20 on which the nick 50 is not formed so that the rupture of the nick 50 .

8 shows a case where a part of the pusher 140, the nick 50 formed on the paperboard 20, and the protrusion 240a are positioned in a straight line.

In this case, as shown in FIG. 7, the pressing portion 140 presses the nick 50, and a part of the protrusion 240a, which receives the pressure by the pressing portion 140, is lowered and then restored to its original state.

At this time, the protrusion 240b outside the protrusion 240a receiving the pressure of the pressure unit 140 supports the cardboard 20 on which the nick 50 is not formed to assist the nick 50 in breaking.

The nick 50 formed on the cardboard 20 is broken by the interaction of the pressing unit 100 and the supporting unit 200 as described above. 6 to 8, there is an advantage that the separate uniting of the pressing unit 100 and the supporting unit 200 is not required by the supporting unit 200 of the nick braking apparatus of the present invention.

This is very effective for a nick braking device in which the cutting device is changed by the surrounding environment and is periodically replaced. In other words, since the cutting apparatus does not need a separate aligning step, the pressing unit 100 and the supporting unit 200 can be replaced quickly.

The support unit 200 of the inventive knocking braking device made of an elastic body is more economical than the knocking braking device composed of the conventional two-way cutting device.

The pressing portion 140 may be spaced apart from the first base portion 160 in the axial direction. And the support unit 200 may be formed at a position corresponding to the pressing portion 140. [

It is possible to use a device capable of simultaneously breaking cartons 20 formed with nicks 50 at different positions instead of breaking the nick 50 formed at the same position in the carton 20.

For example, when at least two rails are installed in the nick braking apparatus of the present invention and the position of the nick 50 formed on the cardboard 20 inserted into each rail is different, the pressing portion 140 is moved in the axial direction The nicks 50 of the cardboard 20 inserted into the two rails can be broken at the same time.

The user can simultaneously process the nick 50 formed at any position of the various cartons 20 through the above-described apparatus, so that the nick 50 can be broken quickly and economically.

The nick braking device of the present invention may also be configured to include a frame, a transfer unit, a pressing unit 100, and a support unit 200 without the protrusion 240 as shown in FIG.

Figure 10 is a view of a support unit 200 without the protrusion 240 of the inventive nick braking device.

The frame, the conveying unit and the pressurizing unit 100 may be configured as described above. However, the supporting unit 200 may be formed such that a part thereof does not protrude.

For example, the support unit 200 may be formed of an elastic body covering the entire second shaft 220. In this case, the support unit 200 can support the periphery of the pressing portion 140 formed in the pressing unit 100 without a separate protrusion 240. Therefore, the support unit 200 in which the protrusion 240 is not formed can also have an effect similar to that in the case where the protrusion 240 is formed.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
