Description

Functional saw blade cutting device with dust collection function for residual chips}

The present invention relates to a functional saw blade cutting device including a dust collection function of residual chips, which efficiently collects residual chips generated when an object to be cut made of aluminum or the like is cut by a saw blade, and then collects and treats them to create a safe working environment. It is about a saw blade cutting device that can be guaranteed.

A cutting device (cutting machine or cutting device) is a device that performs a function of cutting a material such as steel, wood, or other metal material, that is, a cutting object into a predetermined size, and has various structures according to the type of current saw blade and the driving method of the saw blade. Cutting devices are widely used in industrial fields.

In general, the principle of cutting a cutting object in a cutting device is to move the saw blade while pressing the saw blade downward or contacting the cutting object sideways, and the cutting object is cut by the saw blade. At this time, the movement (drive) of the saw blade is In a state suspended from a pulley, a method of rotationally driving the conveyor belt method or reciprocating movement around a cutting object may be applied.

In this way, while the saw blade is in contact with the cutting object, it operates with strong pressure and driving force to cut the cutting object.

Splashing of residual chips occurs regardless of the material of the cutting target, but especially in materials such as aluminum, the case where fine powder is blown in all directions is more severe than in other materials. Because of the risk of injury, it is necessary to improve the safety of the working environment.

As a result of investigating the prior art for a cutting device including a dust collecting function, a strip-shaped thin plate material cutting device having a cutting powder suction structure, which is Korean Patent No. 1043773, includes an input unit for conveying the strip-shaped thin plate material to the cutting side; a cutting unit for cutting the strip-shaped thin plate material introduced into the cutting position; a first suction unit configured to suck in cutting chips generated when the strip-shaped thin plate material is cut; a cutting-side roll configured to wind and rotate the strip-shaped thin plate material cut by the cutting part and take it out from the cutting position; a second suction part having one end formed long to surround the upper side of the strip-shaped thin plate material and having the other end bent while being curved along the cut-side roll; a discharge-side roll configured to wind and discharge the strip-shaped thin plate material that has passed around the cutting-side roll to the outside; a suction pipe configured to secondarily suck the cutting chips from the rear side of the cutting-side roll; And a dust collection unit configured to collect the cutting chips through the first suction unit and the second suction pipe. Since it is not scattered and is sucked by the suction pipe connected to the second suction part, it is disclosed that most of the transfer rolls for transporting the strip-shaped thin plate material have a characteristic that can avoid contamination by cutting chips.

However, looking at the above technology, the structure in which the second suction pipe is relatively far from the band saw seems insufficient to prevent the cutting chips from being scattered as far as intended.

Therefore, in a cutting device equipped with a saw blade that rotates in a conveyor belt manner with a head structure including a pair of pulleys, a collector can be installed at the part where the saw blade enters the head to collect dust, depending on the moving direction of the saw blade. There is a need to develop a new and advanced cutting device that predicts the scattering path of residual chips and collects them without scattering them into the air as much as possible.

As can be seen in Figure 1, the cutting device of the present invention is mounted on a pair of pulleys installed at regular intervals in the transverse direction (transverse direction), and the rotation of the pulleys produces a conveyor belt (not shown) method similar to an oval shape. It includes a head 10 equipped with a saw blade 1 rotating in a closed curve.

The head 10 is spaced apart in the height direction from a cutting object such as a pipe made of aluminum or other metal/wood material, and then moved up and down by driving a cylinder to provide a pressing force to the saw blade 1.

1 shows a structure in which the saw blade 1 stands in the vertical (standing) direction. In this case, while the head 10 moves downward, the saw blade 1 touches the upper surface of the cutting target and presses the cutting target at the same time. can be cut

However, it is not necessarily limited to this structure, and in a structure in which the saw blade 1 lies in the horizontal direction, the head 10 moves forward toward the cutting target and presses the saw blade 1 while touching the side (front) of the cutting target. It is also possible, of course, to cut the cutting target.

Since the head 10 may refer to patents or known technologies for cutting devices of the present applicant, a detailed description thereof will be omitted.

The main feature of the cutting device of the present invention is that it includes the collector 100 and the dust collector 200 in a state in which the above-described head 10 is mounted.

Referring to FIG. 1, the dust collector 200 is installed on one side of the head 10, more specifically around the pedestal, which is the lower side of the cutting target, that is, around the ground, and the cutting target is cut by the movement and rotation of the saw blade 1 It is a device that collects and treats generated scattering or residue (in the present invention, this is referred to as 'residue chip') to prevent scattering in the air.

The dust collector 200 is connected to the collector 100 to be described later through a connection pipe 210, and provides a function of suctioning the remaining chips collected in the collector and then collecting and processing the dust.

The dust collector 200 may be equipped with a compressor or a motor/pump to provide suction power to the collector 100 through the connection pipe 210, and the collector 100 can collect the remnant chips through this suction force. provides a foundation for

The dust collector 200 may include various known dust collecting means, that is, the dust collector 200 of the present invention is not limited to a specific structure. Residual chips collected and processed by the dust collector 200 may be discharged to the outside through a separate discharge pipe (not shown).

The collector 100 of the present invention is a key component that determines the characteristics of the present invention, and the saw blade 1 is installed on one side where the head 10 enters the head 10 (periphery of the pulley side), and the cutting target is the saw blade 1 It includes a housing 110 providing a space for collecting residual chips generated by being cut into.

In this collector 100, the housing 110 is connected to the connection pipe 210 of the dust collector 200 mentioned above, and the residual chips are collected through the suction force of the dust collector 200 provided through the connection pipe 210 into the housing ( 110) Residual chips are collected by the principle of suction as if sucking into the inside.

That is, the cutting device of the present invention provides a function to prevent the residual chips generated during cutting of the saw blade 1 from being scattered into the air to harm the health of workers and easily contaminating the working environment. When made of this aluminum material, the residual chips are not only pulverized into fine particles, but also have sharpness, which can cause more fatal injuries to workers, but it serves to effectively prevent such problems.

In particular, in the cutting device of the present invention, since the collector 100 is installed at the part where the saw blade 1 enters the head 10 side to provide a suction force, the saw blade 1 moves toward the head 10 side by inertia. It provides the main characteristic of being able to instantly absorb and collect the concentrated residual chips, further minimizing the problem of scattering residual chips in the air.

Additionally, the cutting device of the present invention can be largely divided into two structures of the collector 100, which are divided into the first and second embodiments of the collector 100 to be described below, respectively.

2 is a perspective view showing a structure of a collector according to a first embodiment, and FIG. 3 is a perspective view showing FIG. 2 from another angle.

That is, as the saw blade 1 enters the slit 100a, it provides an alignment function that can reduce the vibration and vibration of the saw blade 1, so that the saw blade 1 can stably enter the head side, as well as the saw blade 1 ), it provides a function to collect residual chips scattered around in an enclosed space after primarily removing the residual chips from the slit 110a.

In other words, the housing 110 of FIGS. 2 and 3 serves to collect residual chips around the saw blade 1 as well as residual chips buried in the saw blade 1 itself or caught between the teeth of the saw blade 1 can be done

On this basis, the collector 100 of FIGS. 2 and 3 includes a plurality of guide rollers 120 installed in the inner space of the housing 110, which is the rear end side of the slit 110a, to additionally align the saw blade 1. .

The guide roller 120 is provided with at least one pair of rollers so that the saw blade 1 passes between the pair of rollers so that the saw blade 1 entering the slit 110a does not shake due to residual recoil and the housing 110 It provides a role to stably move into the interior of the head 10 through the closed space of the. Of course, residual chips may be additionally collected from the saw blade 1 passing through the guide roller 120 .

At this time, a mechanical means for driving the guide roller 120 may be installed at a portion of the housing 110 in contact with the guide roller 120 .

That is, in the present invention, the durability and durability of the saw blade 1 are improved by collecting the residual chips scattered around the saw blade 1 and cleanly collecting the residual chips remaining on the saw blade itself through the slit 110a or the guide roller 120. It also provides a feature that secures cutting power as well.

The guide rollers 120 may be formed of one pair of left and right or top and bottom, one of left and right sides, or one of upper and lower sides based on the entry direction of the saw blade 1, or a plurality of rollers may be included on each of the left and right sides. .

In addition, the installation position may also vary depending on the direction of the saw blade 1. For example, when the saw blade 1 is vertically (standing), one pair of left and right or left or right sides based on the entry direction of the saw blade 1 It can be installed on any one part of the right side, and when the saw blade 1 is arranged horizontally, it can be installed on one pair of upper and lower sides or on one of the upper and lower sides based on the entry direction of the saw blade 1.

That is, the collector 100 of FIGS. 2 and 3 serves to collect the chips remaining on the saw blade 1 while accommodating the saw blade 1 in a state where the saw blade 1 is installed at the site immediately before entering the head 10. provides

According to the collector 100 according to FIGS. 2 and 3, the residual chips around the saw blade 1 as well as the residual chips on the saw blade 1 can be collected by physically contacting the slit 110a and the guide roller 120. In addition, it has the characteristics of providing a stable moving path of the saw blade 1 and durability and cutting force at the same time.

4 is a perspective view showing a structure of a collector according to a second embodiment, and FIG. 5 is a perspective view showing a structure for adjusting the angle of a C-shaped cover.

The second embodiment of the collector 100 according to FIGS. 4 and 5 further includes a block 130 , a guide roller 120 , and a supporter 140 in a state including the housing 110 .

The block 130 refers to a block structure through which a slit 110a for accommodating the saw blade 1 is passed in a state disposed on the entry end side of the saw blade 1 around the head 10 .

That is, unlike the collector 100 of FIGS. 2 and 3 having an enclosed space, the collector 100 of FIGS. 4 and 5 is a plate-shaped body spread perpendicular to the moving direction of the saw blade 1 at the entry end side of the saw blade 1. The housing 110 surrounds the block 130 through which the slit 110a passes through, and may be referred to as an open structure based on the moving direction of the saw blade 1.

The guide roller 120 is installed at the back of the block 130, that is, at the rear end of the block 130 to align the saw blade 1, and is a pair of rollers similar to the guide roller 120 of FIGS. 2 and 3. is installed to guide the saw blade between the teeth.

Like the guide rollers 120 of FIGS. 2 and 3, the guide rollers 120 of FIGS. 4 and 5 also have a pair of left and right or top and bottom, or any one of the left and right sides, or the top and bottom sides based on the entry direction of the saw blade 1. It is also possible that a plurality of rollers are provided on each of the left and right sides, or the installation position may vary depending on the direction of the saw blade (1).

The support 140 is a structure supporting the guide roller 120, and mechanical means for driving the guide roller 120 as well as supporting the guide roller 120 may be installed.

For example, in FIG. 4 , it can be seen that the block 130 is mounted on the front end of the support 140 .

Based on this structure, the housing 110 of FIGS. 4 and 5 extends along the circumference of the moving path of the saw blade 1 with one side open, and the block 130 and the guide roller 120 as well as the support It consists of a cover 111 surrounding at least a part of (140).

That is, if the housing 110 of FIGS. 2 and 3 has a structure closed on all sides so that only the slit 110a penetrates therein, the housing 110 of FIGS. 4 and 5 has a saw blade 1 It can be said to have a structure with a minimum volume and space capable of wrapping the block 130 and the guide roller 120 (including a part of the support) in a state in which the front and rear are open based on the moving direction of the.

Although not shown in FIGS. 4 and 5, the connection pipe 210 of the dust collector 200 is internally formed on one side of the inside of the housing 110.

According to the second embodiment of the collector 100 according to FIGS. 4 and 5, like the collector 100 of FIGS. 2 and 3 described above, the residual chips remaining on the saw blade 1 itself are collected through the slit 110a. In addition to being able to do so, the cover 111 provides an additional feature that can secure a sufficient collection space as much as the block 130 and the guide roller 120 are sufficiently wrapped.

Furthermore, the cover 111 of FIGS. 4 and 5 surrounds the block 130 and the guide roller 120, and the C-shaped cover 112 that can be opened by the hinge 112a, and the top of the C-shaped cover 112 It is possible to include a bent portion 113 bent and extended to contact the upper surface of the support 140 in the.

The C-shaped cover 112 is schematically equipped with a hinge (hinge) 112a at the central portion, so that the upper and lower parts divided based on the hinge 112a can be gathered or opened together, in the present invention, the C-shaped The open state of the cover 112 is called an open state of the C-shaped cover 112 .

The bent portion 113 serves to provide a surface area on which the C-shaped cover 112 can be stably mounted on the upper surface of the support 140 . In other words, due to the curved shape of the C-shaped cover 112, the bent portion 113 solves the problem of insufficient surface area for the end of the C-shaped cover 112 to contact the upper surface of the support 140. can

According to this cover 111, the housing 110, that is, the C-shaped cover 110, which provides a collecting space in the collector 100, can be opened by a simple operation of the operator, so that the guide roller 120 and the like can be opened. It may have characteristics that provide convenience in cleaning and simplicity in maintenance.

In addition, referring to FIG. 5 , it can be seen that the adjustment hole 114 having a screw thread is formed through the upper surface of the bent portion 113 and the support 140 .

In addition, an adjusting pin 115 having a screw thread formed on an outer circumferential surface may be coupled to the adjusting hole 114 while being extended to a certain length.

According to this, the angle at which the C-shaped cover 112 is mounted on the upper surface of the support 140 is adjusted by adjusting the threaded coupling depth of the control pin 115, that is, the installation angle of the C-shaped cover 112 can be adjusted, In this way, by adjusting the angle of the C-shaped cover 112, it has a characteristic that provides an advantage of being able to adjust the collection position or collection direction of the residual chips.

6 is a perspective view showing the concentration of the alignment unit.

The bracket 151 has a 'c' shape protruding toward the moving direction of the saw blade 1, and is mounted on the front surface of the support body 140.

The rotating shaft 152 is rotatably connected between both protruding ends of the bracket 151, that is, refers to a shaft installed rotatably between both ends of the bracket 151.

The disc 153 is a structure that is coupled to the rotating shaft 152 and rotates in contact with the saw blade 1 when the saw blade 1 moves.

4 to 6, it can be seen that the disc 153 extends in the horizontal direction. In this case, the saw blade 1 may also extend in the horizontal direction, but is not necessarily limited thereto, and the disc 153 extends in the vertical direction. In this case, the saw blade 1 may be mounted so as to stand upright in the vertical direction.

That is, the disc 153 serves to guide the stable movement path of the saw blade 1 while in contact with the front or rear surface of the saw blade 1, so that the saw blade 1 bounces or severe vibration occurs in the slit 110a. As a result, it is possible to provide a basis for more stably collecting the saw blade 1 and the residual chips around it in the collecting space of the housing 110 while ensuring stable mobility of the saw blade 1. have.

Furthermore, the disc 153 may be formed of a composite beyond being composed of a single body, specifically, a pair of first discs 153a and a pair of discs stacked between the pair of first discs 153a. It is possible to consist of a second disc 153b having a larger diameter than the first disc 153a.

At this time, the second disc 153b rotates while slightly touching the saw blade 1 so as to come into contact with either the front or rear surface of the saw blade 1 and serves to guide the first disc 153a. (153a) provides a function of performing a guide for securing a stable path of the saw blade (1) by rotating while substantially contacting the saw blade (1).

That is, the second disc 153b has a larger diameter than the first disc 153a, and is preferentially thicker than the second disc 153b in a state where the saw blade 1 can slightly contact the second disc 153b. It can be said that it is processed so that the saw blade 1 can stably come into contact with any one of the pair of first discs 153a.

In summary, the disc 153 is embodied as first and second discs 153a and 153b that are stepped to have different diameters to guide the saw blade 1 more stably and at the same time make contact with the saw blade 1 without misalignment. It provides characteristics that can ensure an environment where

Additionally, as can be seen in FIGS. 4 and 6, the aligning unit 150 includes a plurality of moving bars 154 coupled to one side of the bracket 151 to move along the moving direction of the saw blade 1, It is possible to include a control means (not shown) for controlling the movement of the moving bar 154 .

That is, the disk 153 mounted on the bracket 151 can be moved forward and backward based on the moving direction of the saw blade 1, and when the disk 153 mounted on the bracket 151 moves in this way, the disk It is possible to provide a feature capable of adjusting the position or part of the saw blade (1) in contact with (153), thereby having the advantage of being able to select the part where alignment of the saw blade (1) is required.

At this time, the moving bar 154 may be formed of a mechanical means capable of extension and contraction, such as a cylinder, and the control means may include an element for controlling the extension and contraction of the mechanical means.

As shown in the drawing, the moving bar 154 may also have a structure in which one or more cylinders are extended.

The alignment unit 150 conveniently adjusts the alignment position of the saw blade 1 in rapidly changing situations such as vibration and vibration of the saw blade 1, and as a result, the saw blade 1 stably enters the collector 100. Thus, an environment in which residual chips can be easily collected can be provided.

As described so far, the configuration and operation of the functional saw blade cutting device including the dust collection function of residual chips according to the present invention are expressed in the above description and drawings, but this is only an example and the spirit of the present invention is not reflected in the above description and It is not limited to the drawings, and various changes and changes are possible without departing from the technical spirit of the present invention.
