Description

A cylindrical saw device

The present invention relates to a cylindrical saw apparatus capable of easily extracting the center of a wood into a cylindrical shape.

Generally, in order to use wood obtained from forests in building materials or furniture, various types of processing are carried out, and a material processing for forming necessary raw materials is performed. The wood material is formed by firstly forming a wood block with a predetermined thickness using a cutting means such as a band saw, and then subjecting the second wood block to a shape necessary for building materials or furniture.

However, in general, large-sized woods used in hanok or houses are generally made of cylindrical or polygonal wood. In this case, the weight of the wood used is so heavy that it is difficult to carry and the construction is difficult. There is a problem that cost and time are lost, for example, structural reinforcement work must be performed due to overage of the structure.

In particular, in the case of modern buildings, wood is used in terms of interior, health, and environment rather than structural aspects. Therefore, it is becoming more and more necessary to rework wood with a structure that is light and easy to carry and has an interior space of wood. However, in such a case, there is no suitable saw or cutting tool for providing the center of the large-sized wood as an empty space, and it is necessary to develop a device for cutting and processing the inside of the wood to maximize the utilization of the wood.

Figs. 2 and 3 are conceptual diagrams for explaining the main configuration of Figs. 1A and 1B.

Referring to FIGS. 1A and 2, a cylindrical top apparatus (hereinafter referred to as "the apparatus") according to an embodiment of the present invention has a hollow interior and a first outer peripheral surface in the longitudinal direction A second body part 200 disposed inside the first body part and having a second outer circumferential surface spaced apart from an inner surface of the first body part, And a plurality of cut pieces coupled to a side surface of the second body part to apply a fluid to the space B between the first body part 100 and the second body part 200. [ And a driving unit 500 coupled to the first body 100 or the second body 200 to apply a rotational force to the first body 100 or the second body 200. The nozzle unit 400 includes at least one nozzle .

As shown in FIG. 1, the first body part 100 may have a cylindrical outer circumferential surface, and may have a hollow interior. Particularly, one end of the first body part 100 may be coupled with a plurality of cut pieces constituting the cut part 300, and the other end may be coupled with the drive part 500 as described above. Of course, in this case, as described later, the driving unit 500 may be combined with the other end of the second body 200 (see FIG. 4). The material of the first body part 100 may be formed of a metal material or an alloy material of various metals so as to withstand the high temperature by friction with the inside of the wood.

The second body part 200 is arranged to be inserted into the first body part 200 and the inner surface of the first body part 100 and the outer surface of the second body part 200 (Hereinafter referred to as " spacing portion B "). The second body part 200 may also be a cylindrical shape having a hollow interior (hereinafter referred to as a hollow part A).

The first body part 100 and the second body part 200 are arranged to be spaced apart from each other as shown in FIG. 1, and a cut part 300 formed of a plurality of cut pieces at each side end part, So that mutual coupling can be achieved. The cutter is a structure that functions as a saw blade. The cutter cuts the central portion of the wood by the rotational force of the first body portion 100 and the second body portion 200 in contact with the surface of the wood, .

That is, the cutting piece according to an embodiment of the present invention functions as a structure for separating the first body part 100 from the second body part 200, and implements the function of the saw blade, So that it can perform cutting function. In this case, the cut pieces may be embodied in various shapes as shown in FIG.

The nozzle unit 400 may be disposed in a space between the first body 100 and the second body 200 and may include the first body 100 and the second body 200, 200 and is fixed to the first body part 100 and the second body part 200 so that they are not rotated when the second body part 200 rotates. At least one nozzle constituting the nozzle unit may be provided. Preferably, two or more nozzles can be provided to increase the efficiency of sawdust discharge.

The driving unit 500 includes a rotating member such as a rotating plate (a structure with a central opening) capable of rotating the first body part 100 or the second body part 200 at a high speed in a housing having a disk- Allows for strong rotation through the motor. In this case, the nozzles are guided to a space where the center of the rotating plate is opened, so that twisting does not occur when the first body part 100 and the second body part 200 rotate. In addition, it is preferable that the diameter of the housing of the driving unit is less than the diameter of the first body part so that the operation of piling with wood can be smoothly implemented.

1B is a conceptual diagram showing an embodiment of a driving unit having a structure different from that of FIG.

Referring to FIG. 1B, the first body 100 and the second body 200 have the same structure. However, the first body 100 and the second body 200 may have the same structure as the first body 100 and the second body 200, And a rotating plate for fastening the first body part 100 and the second body part 200 by fastening the first body part 100 and the second body part 200. The first housing 501 is connected to the first housing 501 and the bearing part 502 And a second housing 503 which is hermetically sealed and applies high-pressure air to the inside of the first housing. When the high pressure air is introduced into the second housing 503 by the high pressure air injector P, the high pressure air is transferred to the first housing 501 to be communicated, So that the air pressure can be ejected into the first body part 100 and the second body part 200. In this case, at least one nozzle is also arranged to facilitate the discharge of the sawdust. The first housing 501, the bearing 502 and the second housing 503 are all formed with a central opening so that the first body part 100 and the second body part 200 So as to be integrally connected with the open space of the central part of the vehicle. This is for the purpose of allowing the wick of the wood to be cut to be inserted into the space at the center and being discharged to the rear at the time of the later cutting operation.

Also in this embodiment, the diameters of the first housing 501, the bearing 502 and the second housing 503 are less than the diameters of the first body 100, It is preferred that the cylindrical sawing device pass through the interior of the wood.

1A and 3, the cutting tip has one end a coupled with an end of an outer circumferential surface (first outer circumferential surface) of the first body part 100, and the other end b coupled with a distal end of the second body part 100 (Second outer circumferential surface). In particular, the cutting piece may be configured to include a cutting edge 311 and a support 310 (see FIG. 3 (c)) for supporting the cutting edge 311. In order to easily dig a surface of the wood and cut it, the cutting blade-attached or cutting blade 311 portion is formed on the imaginary outer side surface X of the first body portion and the side surface of the second body portion, The protrusions can be formed so as to protrude from the protrusions.

The nozzle unit 400 allows the fluid such as high-pressure compressed air to be applied to the spacing portion B. This causes the sawdust to move into the space between the first body part and the second body part which pierce the central part of the wood by the high-speed rotation, and it can discharge it to the rear by applying high-pressure air. For this purpose, a discharge groove 110 may be formed in one area of the first body part 100.

The function of the cutting action and the sawdust discharge of the present apparatus will be described with reference to Figs. 1 and 4. Fig.

The cutting portion 300 of the apparatus approaches the direction x of the surface of the wood W to perform the cutting operation so that the first body portion 100 and the second body portion 200, The cylindrical saw apparatus integrally coupled to the rotating shaft 300 is rotated. When the surface of the wood (x) comes into contact with the cut part (300), the cutting piece cuts the surface of the wood by the high rotational force and rotates, progressing gradually toward the center part of the wood (w) Is inserted into the hollow part (c) of the second body part (200). The cut central portion of the wood w inserted into the hollow portion c of the second body portion 200 may be discharged to the outside by various methods such as manually discharging the cut portion to the outside or discharging it to the outside by using a separate device Can be discharged.

When such a cutting operation is performed, a large amount of sawdust is generated. This sawdust moves to the separation part between the first body part 100 and the second body part 200 as the apparatus proceeds with the cutting operation. In this case, The air moves along the jetting direction y and then receives the surface of the wood and then reverses it again (z1, z2). By this backward air, the sawdust is discharged (z2) to the outside. In order to more efficiently implement the backward process of discharging the sawdust, a vortex pattern (210, 210 in FIG. 3) for realizing vortex of air in a space between the first body part 100 and the second body part 200, 220 may be implemented. Such a vortex pattern may embody a protruding pattern on the inner surface of the first body part or the outer surface of the second body part. When the vortex pattern is implemented, the air to be injected is advanced to the high-speed high pressure and deformed into an unstable vortex so that the sawdust can be more effectively dispersed and reversed in the stagnant section.

Figure 3 also shows various shapes of the second body portion. As shown in FIG. 3, the vortex patterns 210 and 220 may be formed in a protruding shape. However, the vortex patterns 210 and 220 may be realized by a sawdust guide groove structure having a structure that penetrates the second body portion, So that a part can be guided to the body part. The sawdust guided to the first body part is cut and the deep part of the wood entering the hollow part c is pushed backward so that it can be removed through the discharge groove of the first body part or the second body part It is also possible to implement.

5 is a perspective view of a cylindrical top apparatus according to another embodiment of the present invention. The difference from the structure of FIG. 1 is that the configuration of the driving unit 500 is implemented to be coupled to the end of the second body part 200, and the distal end 330 of the separation part can be implemented as an open structure.

1, the driving unit 500 may include a rotating member such as a rotating plate structure coupled to the other end of the second body part, a driving motor M for rotating the rotating member, ). &Lt; / RTI >

5, the rotation member may include a rotation applying member 510, 520 which is coupled to a distal end of the second body portion. In this case, 1 < / RTI > body. In this case, the distal end 330 of the separation part is communicated with the outside, and the discharge of the sawdust can be naturally realized at the distal end 330 by air inflow of the nozzle part 400.

However, in this embodiment, when the core of the wood is drawn into the space of the central part where the second body part 200 is opened, the wood is hardly discharged by the rotation applying members 510 and 520, The cutting operation is performed by the length of the wood corresponding to the length of the second body portion.

The nozzle unit according to the embodiment of the present invention can be implemented by various apparatuses capable of spraying a high-pressure fluid. For example, the air compressor may include an air compressor that provides high-pressure air to the spacing space, and a nozzle tube that guides compressed air from the air compressor to the spacing space.

The apparatus may further include a lubricant supply unit (not shown) that communicates with the nozzle pipe and introduces the lubricant into the nozzle pipe. 4, when the cutting operation is performed to pinch the center of the wood by the high-speed rotation of the apparatus, the lubricant supply unit may be provided with friction resistance or thermal resistance due to friction on the outer and inner surfaces of the first and second body portions, So that the cutting operation may not be smoothly realized. In this case, the lubricant is sprayed into the air injected through the nozzle portion, so that the lubrication action can be realized on the surface of the second body portion and the inner surface of the first body portion, and the cutting operation can be efficiently performed. In this case, as shown in FIG. 2, lubricant diffusion grooves 114 and 214 (see FIG. 2) penetrating the first body portion and the second body portion are provided to evenly supply lubricant to the inner and outer surfaces, Efficiency can be increased.

1 to 5, when the cylindrical saw apparatus according to the embodiment of the present invention is disposed, the wood W is transferred by the rope or the like using the transfer rollers Rx, Rx, and Rz of the wood transfer apparatus R Transfer. Then, the wood W is placed on the conveying type stage S such as a conveyor belt, and is moved to the position of the cylindrical saw apparatus.

Then, the first and second body portions including the surface of the wood and the cutting portion of the cylindrical saw apparatus rotate at a high speed, and the central portion of the wood is processed by the action described above in Fig. 4. The sawdust Z1, And is stored in the portion (H). 1 and 5, the rotational force is applied to the motor M. In the air compressor P, the compressed air is supplied to the first body portion and the second body portion, 2 It is discharged to the space between the body parts, so that the sawdust can be discharged smoothly by using the backward phenomenon of the air.
