Description

Column vertical vertical and horizontal cutting device using saw {COLUMN MOVING TYPE VERTICAL AND HORIZONTAL CUTTING MACHINE USING SAW}

The present invention relates to a column transfer type vertical and horizontal cutting device using a saw, and more particularly, the cutting target positioned on the workbench is fixed to the workbench while the column on which the saw is mounted is moved up and down and back and forth. The present invention relates to a cutting device for cutting a cutting object, wherein the saw is moved up and down, that is, in a vertical manner, as well as being rotated in a horizontal manner to more freely cut the cutting object.

 Cutting devices are also named under various names such as cutting machines, cutting devices, etc. These cutting devices refer to a machine that cuts various materials such as metal and wood according to specific dimensions. Cutting machines with various functions have been developed due to differences in dimensions and the like.

When the cutting method is exemplarily described, there is a method of cutting while the cutting object is fixed and the cutting edge moves, and, conversely, a cutting edge is fixed and the cutting object is moved by a conveying means.

Among the methods in which the cutting target is fixed at a specific position and the cutting edge is moved, the cutting target is fixed on the work table or transferred to a specific position by a conveying belt, and the cutting target is cut while the cutting edge moves up and down from the upper cutting target. This exists, especially when the cutting object is a hard material such as metal, the cutting edge is rotated and at the same time it can move the cutting object from the top to the lower part where the cutting object is located while cutting the cutting object while applying a load to the cutting object. In addition, it is widely used in terms of giving safety to work, and it is also called a shaping machine.

However, in such a cutting method, when the cutting edge is rotated in contact with the metal, the cutting edge is often caught or engaged between the cutting portions. In this case, the cutting process may be delayed because the cutting object must be separated from the cutting edge. In addition, the trouble of the operator was encouraged and even the cutting edge could be broken.

Referring to the present disclosure, it can be seen that a lot of things that give the cutting machine a vibration function are disclosed. However, since most vibration sources (springs, ultrasonics, etc.) are directly connected to the cutting edge itself, the cutting edge is applied to the cutting edge in order to vibrate in a state where the cutting object can be precisely cut without being shaken at the set point. There is a problem that the means for precisely adjusting the vibration becomes complicated, and there is a problem that there is a possibility that the control of the precision of the vibration is not detailed.

The present inventors use a band (or chain / belt) shaped saw wound around the pulley in addition to a circular saw (circular saw) when cutting a cutting object made of metal or the like (hereinafter referred to as a 'cutting object'). In the cutting device, the cutting object is transported near the saw for cutting. In this case, it is recognized that various cutting methods of the saw cannot be presented. In this case, the cutting target is fixed and the cutting target can be cut while the saw moves up and down. In order to ensure the diversity and efficiency of the cutting process, while the belt-shaped saw is standing vertically, it is necessary to develop a model to conveniently achieve the vertical and horizontal cutting process of the saw. Reached.

Specifically, the cutting device according to the present invention is a cutting assembly having a saw 1 in the form of a belt wound on a pulley 7 installed on each of the left and right sides of the head 20, that is, the column 10 is cut. It consists of a cutting machine having a method of cutting the cutting object while moving up and down and back and forth at regular intervals during the cutting process on the worktable 7 (the worktable may be equipped with a movable belt) on which the object is seated. In the cutting device according to the present invention, as the head 20 installed in the column 10 standing vertically upwards of the work table 7 descends toward the work table, the saw 1 contacts the cutting object 2 and pulleys. The cutting object is cut by the rotational force and load applying method by the rotation of (5), and the head 20 is moved upward again and then moved back and forth along the horizontal direction against the position of the subsequent cutting object.

As can be seen from Figures 1 to 3, the column 10 is composed of a head 20 located on the front side and a supporter 25 for supporting the head 20 behind the head.

The head 20 and the supporter 25 are provided with a recess 29, i.e., formed into a U-shape with a c-shaped rotated 90 degrees clockwise and sawed on the cutting target 2 placed on the work table 7. When (1) is close, the head 20 and the supporter 25 are prevented from hitting the cutting object (2) or the problem that a collision occurs.

In addition, the recess 29 is chamfered on both sides of the upper edge (corner), i.e., the upper edges of the recess 29 are cut off on both sides so that the upper edge is recessed. One chamfer processing portion 29a is provided. The chamfer processing portion 29a is recessed when the head 20 is lowered and the cutting object 2 enters or is adjacent to the recess 29. (29) It prevents the head from being caught in the space or touching the upper surface of the recess 29 to prevent the head lowering degree from being excessive when the head 20 is lowered or by colliding with the cutting object 2. It serves to buffer the impact acting on (20).

The head 20 has a pair of left and right pairs of pulleys 7 formed in one pair of left and right sides and a saw 1 held by the pulleys 7, and the detailed configuration of the vertical movement device can be accommodated or attached thereto. Provide space for

The pulley 7 is rotated by the power of a driving motor (not shown), and is composed of a pair of left and right, and is composed of a main pulley 5 and an auxiliary pulley 5a, respectively. Rotate

The saw 1 is wound around the pulley 7 to be circulated in one cycle by the rotation of the pulley 7, so that the cutting object 2 can be cut by this rotation of the saw 1. . The saw 7 connected to the pulley 7 is exposed to the outside at the recess 29 of the head 20, and this part comes into contact with the cutting object 2.

 The vertical moving device according to the present invention serves to drive the head 20 up and down in the column 10, and the front and rear moving device moves the column 10 including the head 20 and the supporter 25 horizontally back and forth. In this invention, the vertical movement device and the front and rear movement device can be configured in various mechanical ways, but in the present invention, the vertical movement device is composed of a servo motor and a ball screw, and the front and rear movement device is made of a rack / pinion method. It demonstrates with an example.

The first servo motor 30 constituting the vertical movement device rotates the first shaft 31 extending in the left and right directions, respectively, and has a total of two balls respectively connected to the first shaft 31 by the bevel gear 32. The rotational force is provided to the screw 33, wherein the ball screws 33 on each of the left and right sides are in contact with the threads of the supporter 25, and the first servo motor 30 is coupled with the threads of the supporter 25. The head 20 can be moved up and down in accordance with the rotation direction of the.

The front and rear movement device is composed of a pair of left and right pairs of LM guides 45 and a rack 44 and pinion (not shown) and a second servo motor 40 which are also composed of a pair of left and right pairs. The third shaft 43 is rotated while the power of the second servo motor 40 is transmitted to the second shaft 41 and is vertically connected to the second shaft 41 via the bevel gear 42. 3 When the pinion mounted on the lower end of the shaft 43 rotates, the rack 44 coupled to the pinion moves along the LM guide 44 on the base 3 to move the column 10 forward and backward. To be moved.

Figure 4a is an enlarged perspective view showing a specific configuration of the horizontal rotating module according to the present invention, Figure 4b is a perspective view showing the horizontal rotating module from another angle.

The horizontal pivot module 200 according to the present invention is provided at the bottom of one side of the head 20 to provide a space for accommodating a part of the length of the saw 1 exposed to the recess 29 side, specifically, the hydraulic cylinder 210 and the fixing bracket 220, the bearing bush 230 and the saw blade guide 240, the housing 250 is composed of.

The hydraulic cylinder 210 is formed in the longitudinal direction downward in a state fixed to the fixing bracket 220 mounted on one side of the head 20 to the power transmission means formed on the fixing bracket 220 (or its periphery). It is stretched downward or contracted back to its original position.

The housing 250 provides a space in which the bearing bush 230 and the saw blade guide 240 are integrally coupled and rotated in a state in which a part of the saw 1 is accommodated through the through hole 255. It is located below the fixing bracket 220.

The bearing bush 230 is formed in a ring shape so that the saw 1 passes through the ring-shaped inner space and is connected to the lower end of the hydraulic cylinder 210, and at the same time, the saw blade guide ( It is formed integrally with 240, when the hydraulic cylinder 210 is extended downward is rotated 90 ° counterclockwise through the bearing medium, the saw blade guide integrally coupled when it is rotated in this way 240 also provides a function to be rotated.

The saw blade guide 240 is integrally coupled with the bearing bush 230 so as to be rotatable within the through hole 255 of the housing 250 and provides a space, namely a hole, to accommodate a partial length of the saw 1. The hole extending toward the opposite side of the bearing bush 230 has a larger area than the longitudinal area of the saw 1, for example, has a rectangular shape having a longitudinal length longer than the horizontal length, so that the saw 1 is When the vertical state is taken, the bush 1 for bearing 230 is lowered by the hydraulic cylinder 210 while allowing the saw 1 to rotate smoothly according to the rotation of the pulley 5 without touching or interfering with the saw 1. ) Serves to lie down the saw (1) standing vertically in a horizontal direction while rotating 90 ° like when rotating 90 °.

That is, when the saw blade guide 240 is rotated, the saw 1 passing through the hole of the saw blade guide 240 is pressed against the inner wall of the through hole of the saw blade guide 240 and at least exposed to the recess 29. It can be rotated to have this horizontal state.

Since the saw can be switched from the vertical state to the horizontal state through the horizontal rotation module 200, the cutting object provides a characteristic to cut the cutting object in a vertical manner as well as a horizontal state.

5 is a perspective view showing a fixing module according to the present invention.

The fixed module is composed of a pair of left and right to hold the cutting object (2) in the left and right sides so as not to move the front and rear movement by the forward and backward movement device to serve to contact the surface of the cutting object, the vise plate (51) Is supported on the rack 44 and the LM guide 45 by the extension and contraction action of the cylinder 53 extending from the stationary body 52 with the motor and the support 55 in the horizontal direction. It is installed so that sliding movement is possible.

That is, the fixed body 52 is provided with a configuration such as a motor to achieve the expansion and contraction action of the cylinder 53, so that the support 55 to the cutting object 2 by the contraction and extension of the cylinder 53. Can be moved in the horizontal direction and in this way the support can hold the cutting object 2 firmly.

Here, the support 55 is moved back and forth along the rack 44 and the LM guide 45 by the front and rear movement device rather than holding the cutting object 2 in a fixed state, while touching the surface of the cutting object 2. It will be more accurate to express that the object to be cut 2 is held.

A pressure sensor may be additionally mounted on the contact side of the support object 2 on the cutting object 2, and the pressure sensor may measure and measure the pressure applied to the support member 55 by contact with the cutting object 2. The pressure value may be transmitted to the controller 100 to be described later.

Referring back to FIG. 1, the base 3 includes a work table 7 on which the cutting object 2 is seated, and at the same time, the LM guide 45 and the rack 44, which are one component of the back and forth moving device, are installed. It provides space. The base 3 not only seats the cutting object 2 but also performs a function of supporting the column 10.

6 is a block diagram showing the configuration of a controller according to the present invention.

The controller 100 according to the present invention by controlling the drive motor for rotating the pulley 5, the cylinder 53 of the fixed module and the first and second servo motors 30 and 40 of the up and down moving device and the front and rear moving device. By performing the main control function of the cutting device according to the invention, it is possible to provide additional control functions to be described later in addition to the basic control functions.

That is, the controller 100 may further include a rising differential control module 110, which is two pressure sensing sensors 111 additionally mounted on one side (portion of contact with the saw) of the pulley 5. And it is interlocked with the horizontal sensor 112.

In the process of cutting the cutting target 2 by the belt-shaped saw 1, the belt-specific saw-specific characteristics may interfere with the cutting process by being caught or engaged in the gap of the cutting target 2 or the saw 2 is raised again. There may be a problem that is not.

In particular, when the saw 1 is pinched by the cutting target 2, when the left and right sides of the long extending saw 1 are the same, that is, when the horizontal lifting and lowering horizontally, the saw 1 is properly removed from the cutting target 2. There is a fear of not coming out.

Therefore, in order to prevent such a problem, the rising differential control module 110 has two pressure sensing sensors 111 formed on one side of the pulley 5 when the saw 1 cuts from the cutting target 2 and then rises again. If the pressure applied to the pressure, i.e., the resistance is determined to be above a certain value (i.e., the pressure value normally applied when the saw blade is not caught in the cutting object), Only the ball screw 33 is driven for a predetermined time, and then the ball screw 33 on the other side is driven so that the saw 1 is not raised horizontally, but is temporarily raised to one side. Then, the saw 1, which is raised in the tilted state toward one side, is corrected back to a horizontal state to rise.

That is, the rising differential control module 110 according to the present invention increases the number of revolutions of the ball screw 33 of one side than the ball screw 33 of the other side or only the ball screw 33 of one side for a certain time Drive so that the saw 1 is pulled out of the cutting object 2, and then the driving control of the ball screw 33 on the other side is carried out, and then the horizontal sensing sensor mounted on one side of the column 10 ( 112) (a kind of optical sensor for measuring height) senses the horizontal state of the saw 1, and if it does not become horizontal level, by differentially controlling the number of revolutions of the two ball screw 33 to be horizontal It is to ensure the horizontal rising state of the saw (1).

In addition, the controller 100 further includes a fixed control module 120, and the fixed control module 120 controls the degree to which the support 55 of the fixed module is pressed against the cutting object 2. The degree of compression of the support 55 is differentially controlled by the hardness input unit 122 for inputting the pressure value of the pressure sensor 121 mounted on the support 55 and the basic characteristics of the cutting target 2. .

Specifically, the user or the operator inputs the hardness of the cutting object 2 through the hardness input means 122 (which can be understood as a kind of input device having a key) so that the hardness of the cutting object 2 can be understood. First, the pressure of the support 55 to be applied to the cutting object 2 is measured (that is, set), and the support 55 is slid to move to the cutting object 2 so as to contact the cutting object 2. By applying the pressure to the cutting target 2 by controlling the driving of the (2) at this time, the pressure value applied to the support 55 through the pressure sensor 121 to secondly measure the pressure value applied to the actual support 55 Finally, the pressure to be finally applied to the support 55 is corrected or determined to provide the characteristic of fixing the cutting object 2 to the pressure of the finally determined support 55.

Referring to the operation of the cutting device according to the present invention having such a configuration as follows.

The cutting target 2 seated on the work table 7 comes into contact with the support 55 by the extension of the cylinder 53 connected to the fixed body 52 of the fixed module, and to the fixed control module 120. The cutting target 2 is fixed by the pressing of the support 55 through the control by the control unit.

At this time, since the support 55 can be unnecessarily moved to the cutting object 2 when it is moved by the front and rear movement device when the pressure is applied too hard, the pressure determined under the proper control of the fixed control module 120 is supported ( 55) so that the cutting object 2 provides a position fixing role at a level that will not largely leave the position due to the repulsive force by the saw 1.

In the initial state, the head 20 has a state spaced apart from the cutting object 2, that is, a state of being raised upward. As the cutting device is operated, the head 20 is lowered by the function of the up and down moving device to contact the cutting object 2. The cutting object 2 is cut through the saw 1 rotating circularly by the pulley drive.

When the cutting target 2 is cut, the head 20 is raised upward again, and at the same time or sequentially, the back and forth moving device moves the column 10 along a specific direction (the shape and position of the cutting target and the cutting purpose). The column 10 may be positioned at another cutting position in the cutting target 2.

The front and rear movement apparatus can set and adjust the movement amount of the column according to the preset value by the controller 100, and the degree of moving the column 10 varies depending on the type of cutting object 2 and the cutting purpose. Can be.

When the saw 1 moves up and down (vertically) by the vertical movement device, the saw 1 is vertically erected, so the cutting target 2 is cut in the vertical direction, but the cutting target is cut in the horizontal direction. If necessary, the saw 1 is rotated by 90 ° so as to be positioned in the horizontal direction, and then the cutting object 2 is moved to the horizontal direction by moving the column 10 in the forward and backward directions by the forward and backward moving device. It can cut horizontally.

Specifically, the saw blade guide which is operated (extended) the hydraulic cylinder 210 of the horizontal rotating module 200 to rotate 90 ° counterclockwise and integrally connected to the bearing bush. The saw positioned in the saw blade guide while rotating by 90 ° is rotated by 90 ° so as to be positioned in the horizontal direction, and then the front and rear moving device is driven to cut the cutting object in the horizontal direction.

On the contrary, the hydraulic cylinder is operated (contracted) in the upward direction so that the bearing bush rotates 90 ° clockwise, while the saw blade guide also rotates 90 °, allowing the saw to stand vertically again.

In addition, in the process of cutting the cutting target 2 by the saw 1 with the driving of the vertical moving device, when the saw 1 is caught in the cutting target 2 by the rising differential control module 110 of the controller. The ball screw 33 on the side is driven in such a manner as to increase the rotational speed than the ball screw 33 on the other side, so that the saw 1 is first removed from the cutting object 2, and then corrected in a horizontal state to move up. Let's make it.

As described so far, the configuration and operation of the column transfer type cutting apparatus using the saw according to the present invention have been expressed in the above description and the drawings, but this is merely an example, and the spirit of the present invention is not limited to the above description and the drawings. And, of course, various changes and modifications are possible within the scope without departing from the spirit of the present invention.
