Description

[Technical Field]

[0001] The present invention relates to a machining system and a machining method. [Background technology]

[0002] For example, machining devices that perform machining on relatively large workpieces, such as NC (Numerical Control) routers, have been known for some time. One example of such a machining device mainly includes a processing mechanism, such as a router head or a boring head, that performs predetermined machining on the workpiece, and a movable table on which the workpiece is placed. For example, Patent Document 1 describes a machining device that includes a processing table (movable table) that moves in the X-axis direction and a processing head (processing mechanism) that moves in two axial directions, the Y-axis and the Z-axis, and in which cutting tools attached to the processing head perform machining on a workpiece placed on the processing table. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-005710 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional machining devices such as those described in Patent Document 1, when a cutting tool performs machining on a workpiece placed on a movable table, a large amount of machining debris is scattered, and the scattered debris may get mixed into the drive mechanism that drives the movable table. If machining debris gets mixed into the drive mechanism that drives the movable table, the positional relationship between the machining mechanism that machines the workpiece and the movable table on which the workpiece is placed is shifted from the normal positional relationship, not only reducing the machining accuracy but also potentially causing wear and tear on the drive mechanism and ultimately damage to the drive mechanism. If the drive mechanism that drives the movable table is damaged, not only is it time-consuming to clean the drive mechanism, such as by removing the machining debris, but repairing the damaged drive mechanism is also time-consuming and costly. Therefore, to prevent such problems, it is necessary to properly remove machining debris that has gotten mixed into the drive mechanism that drives the movable table.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a machining system that properly removes machining debris that has become mixed into a drive mechanism that drives a movable table on which a workpiece is placed, and a machining method using the machining system. [Means for solving the problem]

[0006] In order to solve the above problems, according to one aspect of the present invention, there is provided a machining system comprising: a machining mechanism for machining a workpiece; a movable table disposed within a machining space and facing the machining mechanism, the movable table being placed on the workpiece; a stand disposed within the machining space and below the movable table, the stand having a plurality of side grooves extending in the direction of movement of the movable table and a main groove extending in the direction of movement and disposed between one and the other of the plurality of side grooves; a drive mechanism disposed in the main groove and supporting the movable table, the drive mechanism moving the movable table in the direction of movement; and a machining device having an openable cover member that defines a portion of the machining space; and a dust collector that sucks air from inside and outside the machining space and discharges the air from which machining debris has been removed into the main groove.

[0007] The term "intrusion of processing debris into the drive mechanism" as described in the description of one embodiment of this specification below means: This means that machining debris adheres to the screw shaft and / or gets mixed in between the screw shaft and the slider. In addition, in the description of one embodiment described below, the workpiece, cutting tools, vertical movement mechanism, rotation mechanism, discharge device, suction device, multiple suction ports, negative pressure generation source, and opening / closing mechanism are not shown. [Effects of the Invention]

[0008] As described above, the machining system and machining method using the machining system according to the present invention can appropriately remove machining debris that has become mixed into the drive mechanism that drives the movable table on which the workpiece is placed.

Furthermore, the scope of the present invention is not limited to the following exemplary embodiments unless otherwise specified to limit the present invention.

[0011] In the following description, mutually orthogonal X-axis, Y-axis, and Z-axis are defined. The X-axis, Y-axis, and Z-axis are three mutually orthogonal axial directions, and are common to all of the drawings described below. As illustrated in FIG. 1 , a direction along the X-axis as viewed from an arbitrary point is referred to as the X1 direction, and a direction opposite to the X1 direction is referred to as the X2 direction. The X-axis direction is a direction that includes both the X1 direction and the X2 direction. Similarly, mutually opposite directions along the Y-axis from an arbitrary point are referred to as the Y1 direction and the Y2 direction. The Y-axis direction (the direction of movement of the movable table) is a direction that includes both the Y1 direction and the Y2 direction. Furthermore, mutually opposite directions along the Z-axis from an arbitrary point are referred to as the Z1 direction and the Z2 direction. The Z-axis direction is a direction that includes both the Z1 direction and the Z2 direction. Furthermore, the XY plane including the X-axis and Y-axis corresponds to a horizontal plane. The Z-axis is an axis along the vertical direction.

[0012] 1. Embodiment [Machining system configuration] 1 to 3 are diagrams showing an example of the configuration of a machining system 1. FIGS. 1 and 2 are perspective views of the machining system 1, and FIG. 3 is a front view of the machining system 1. The machining system 1 has a machining device 100 and a dust collector 200. Note that a portal frame f and the dust collector 200, which will be described later, are not shown in FIG. 3.

[0013] <Machining equipment> The machining device 100 is an NC router machine having a housing 10, a machining mechanism 20, a movable table 30, a stand 40, a drive mechanism 50, an openable / closable cover member 60, and an operation panel 70. Each of these elements will be described below.

[0014] (Housing) The housing 10 is connected to an openable / closable cover member 60 and defines a part of the machining space W. The housing 10 has gate-shaped exteriors 11 and 12, a protruding portion 13, and a gate-shaped frame f. The gate-shaped exteriors 11, 12, and the protruding portion 13 are connected to each other to form a single unit.

[0015] The gate-shaped exterior 11 extends in the X-axis direction and has a gate-like shape when viewed in the Y2 direction. The gate-shaped exterior 11 has an opening 11h and strips 111 and 112. The opening 11h is formed in the upper part of the gate-shaped exterior 11 and communicates with the processing space W. The strip 111 covers the opening 11h in the Z1 direction, with one end fixed to an edge of the opening 11h located in the X1 direction and the other end connected to the winding device 23. The strip 112 covers the opening 11h in the Z1 direction, with one end fixed to an edge of the opening 11h located in the X2 direction and the other end connected to the winding device 22. In this embodiment, the opening 11h is blocked by the strips 111 and 112 and the processing mechanism 20, thereby sealing the processing space W.

[0016] The portal exterior 12 is disposed on the Y2 side of the portal exterior 11, extends in the X-axis direction, and has a portal shape when viewed in the Y2 direction. The dimension (width) of the portal exterior 12 in the X-axis direction is approximately the same as the dimension of the portal exterior 11 in the X-axis direction, but the dimension (height) in the Z-axis direction is greater than the dimension of the portal exterior 11 in the Z-axis direction. Therefore, the portal exterior 12 has a portion that does not overlap with the portal exterior 11 when the machining apparatus 100 is viewed in the Y2 direction. As shown in FIG. 3 , this portion of the portal exterior 12 is provided with a pair of guide rails G extending in the X-axis direction. Furthermore, the dimension (depth) of the portal exterior 12 in the Y-axis direction is approximately the same as the dimension of the portal exterior 11 in the Y-axis direction.

[0017] 1, the portal frame f straddles the portal exterior 12 in the X-axis direction and extends in the X-axis direction. The portal frame f has a portal shape when viewed in the Y2 direction. As shown in the figure, the portal frame f supports a pipe P1, which will be described later.

[0018] The protruding portion 13 is disposed on the Y2-direction side of the gate-shaped exterior 12 and extends in the X-axis direction. As shown in Fig. 2, the protruding portion 13 is a portion of the housing 10 that protrudes in the Y2 direction from the gate-shaped exterior 12. The dimension (width) of the protruding portion 13 in the X-axis direction is smaller than the dimension of the gate-shaped exterior 12 in the X-axis direction, and the dimension (height) of the protruding portion 13 in the Z-axis direction is also smaller than the dimension of the gate-shaped exterior 12 in the Z-axis direction. Furthermore, the dimension (depth width) of the protruding portion 13 in the Y-axis direction is approximately the same as the dimension of the gate-shaped exterior 12 in the Y-axis direction.

[0019] 2, the rear surface of the overhanging portion 13 facing in the Y2 direction is connected to a plurality of air supply pipes I1 to I3 and a plurality of exhaust pipes O1 to O3. The air supply pipe I2 communicates with a communication passage 44, which will be described later. Each of the air supply pipes I1 and I3 and the exhaust pipes O1 to O3 communicates with the machining space W.

[0020] The exhaust pipe O1 is connected to a hose H1 and communicates with a branch pipe P2 via the hose H1. The branch pipe P2 is connected to a hose (not shown) and communicates with the air inlet 210 of the dust collector 200 via the hose. The branch pipe P2 is also connected to a hose H7 and communicates with the pipe P1 via the hose H7. The exhaust pipe O2 is connected to a hose H4 and communicates with the branch pipe P4 via the hose H4. The branch pipe P4 is connected to a hose (not shown) and communicates with the air inlet 220 of the dust collector 200 via the hose. The exhaust pipe O3 is connected to a hose H6 and communicates with the branch pipe P4 via the hose H6.

[0021] The air intake pipe I1 is connected to a hose H2 and communicates with a branch pipe P3 via the hose H2. The branch pipe P3 is connected to a hose (not shown) and communicates with the exhaust port 230 of the dust collector 200 via the hose. The air intake pipe I2 is connected to a hose H3 and communicates with the branch pipe P3 via the hose H3. The air intake pipe I3 ​​is connected to a hose H5 and communicates with the branch pipe P3 via the hose H5.

[0022] (Processing mechanism) The processing mechanism 20 has a processing head 21 having a drive source such as a servo motor and various mechanisms, and a pair of winding devices 22, 23. The processing head 21 is a processing head that holds a cutting tool for cutting a workpiece, and uses this cutting tool to cut a workpiece placed on a movable table 30 into a desired shape.

[0023] The workpiece to be cut by the machining device 100 according to this embodiment is not particularly limited, but may be, for example, wood such as a piece of wood or a wooden board, metal material such as a piece of metal or a metal board, or resin material such as a piece of resin or a resin board. The cutting tool held by the machining head 21 is not particularly limited as long as it can cut the workpiece, but a cutting tool with an optimum shape or material may be used depending on the material or condition of the workpiece.

[0024] The machining head 21 is provided on the gate-shaped exterior 11, and the portion that holds the cutting tool penetrates the gate-shaped exterior 11 in the Z1 direction and is disposed within the machining space W. The machining head 21 is attached to a pair of guide rails G that extend in the X-axis direction, and slides on the guide rails G in the X-axis direction. Guided by the guide rails G, the machining mechanism 20 traverses vertically above the movable table 30 along the X-axis direction.

[0025] Specifically, as the winding mechanism mounted on the winding device 22 winds up the strip 112 based on the control of the operation panel 70, the processing head 21 slides on the guide rail G in the X2 direction, and as the winding mechanism mounted on the winding device 23 winds up the strip 111 based on the control of the operation panel 70, the processing head 21 slides on the guide rail G in the X1 direction.

[0026] The machining mechanism 20 according to this embodiment may be configured to have a vertical movement mechanism that moves the cutting tool in the Z-axis direction, or may be configured to have a rotation mechanism that rotates the cutting tool in at least one circumferential direction around the X-axis, the Y-axis, and the Z-axis. The machining mechanism 20 may also be configured to have a discharge device that discharges a fluid (e.g., gas or liquid) toward the movable table 30 and / or the workpiece, or may be configured to have a suction device that sucks the area around the cutting tool within the machining space W. If the machining mechanism 20 has a suction device, the machining mechanism 20 is cooled by the suction action of the suction device. In this embodiment, regardless of whether the machining mechanism 20 has a suction device, a blower such as a fan that cools the machining mechanism 20 may be installed.

[0027] (mobile table) Fig. 4 is a partial cross-sectional view taken along line AA in Fig. 3, and Figs. 5 and 6 are explanatory diagrams for explaining the movement of the movable table 30. The movable table 30 faces the machining mechanism 20 in the Z-axis direction and is arranged together with a base 40 in the machining space W. The movable table 30 is configured to be movable in the Y-axis direction as shown in Figs. 5 and 6 while holding a workpiece. The movable table 30 is connected to a drive mechanism 50 arranged on the base 40, and its position in the Y-axis direction is displaced in response to the drive of the drive mechanism 50 (slider 51) in the Y-axis direction.

[0028] The movable table 30 according to this embodiment may have a configuration including a plurality of suction ports for adsorbing a workpiece onto the surface of the movable table 30. Each of the plurality of suction ports is connected to a negative pressure generating source such as a negative pressure pump, and has the function of adsorbing a workpiece onto the surface of the movable table 30 under the control of the operation panel 70.

[0029] (mounting) 7 is a plan view of the mount 40 as viewed in the Z1 direction. The mount 40 is disposed vertically below the movable table 30 and is covered in the Z1 direction by the movable table 30 and the retractable covers Ab1 and Ab2. As shown in FIG. 7, the mount 40 has a main groove 41 and multiple side grooves 42 and 43.

[0030] The telescopic cover Ab1 is a cover that covers in the Z1 direction a portion of the base 40 that is located in the Y2 direction relative to the movable table 30. Covering this portion with the telescopic cover Ab1 somewhat prevents processing debris from getting into the main groove 41 and side grooves 42, 43. One end of the telescopic cover Ab1 is connected to an edge of the base 40 that is located in the Y2 direction, and the other end is connected to the movable table 30.

[0031] The telescopic cover Ab2 is a cover that covers in the Z1 direction a portion of the base 40 that is located in the Y1 direction relative to the movable table 30. Covering this portion with the telescopic cover Ab2 somewhat prevents processing debris from getting into the main groove 41 and the side grooves 42, 43. One end of the telescopic cover Ab2 is connected to an edge of the base 40 that is located in the Y1 direction, and the other end is connected to the movable table 30.

[0032] 5 and 6, the telescopic covers Ab1 and Ab2 are configured to be able to extend and retract in the Y-axis direction in accordance with the movement of the movable table 30. The form of the telescopic covers Ab1 and Ab2 is not particularly limited, but for example, a bellows structure may be adopted.

[0033] The main groove 41 is a groove extending in the Y-axis direction at the center of the frame 40 in the X-axis direction, and is provided between the side grooves 42 and 43. The space defined by the inner surface of the main groove 41 communicates with the air supply pipe I2 via a communication path 44. The dimensions of the main groove 41 in the X-axis direction and the Y-axis direction are not particularly limited, and may be set appropriately depending on the size of the drive mechanism 50.

[0034] The communication path 44 is a flow path provided inside the frame 40, and communicates with the air supply pipe I2, the main groove 41, and the side grooves 42 and 43. The communication path 44 functions as a ventilation path that guides the air supplied from the air supply pipe I2 to the main groove 41 and the side grooves 42 and 43.

[0035] The side gutters 42, 43 extend in the Y-axis direction and are provided on both sides of the base 40. The space defined by the inner surfaces of the side gutters 42, 43 communicates with the air supply pipe 12. There are no particular restrictions on the dimensions of the side gutters 42, 43 in the X-axis and Y-axis directions.

[0036] 8 is a plan view of the mount 40 viewed in the Z1 direction with the blocking portions 42L, 43L (see FIG. 7) that block the through-holes 42H, 43H provided in the gutters 42, 43 removed. As shown in FIG. 8, the gutters 42, 43 have through-holes 42H, 43H at their bottoms located in the Z1 direction. The through-holes 42H, 43H are typically blocked by the blocking portions 42L, 43L. When the through-holes 42H, 43H are not blocked by the blocking portions 42L, 43L, the floor surface F (see FIG. 3) is exposed in the Z2 direction. Note that there are no particular limitations on the dimensions of the through-holes 42H, 43H in the X-axis and Y-axis directions.

[0037] The side grooves 42, 43 according to this embodiment are connected to the movable table 30 and accommodate a connecting member (e.g., a hose) that protrudes in the Z1 direction from the movable table 30. The connecting member moves in the Y-axis direction while being accommodated in the side grooves 42, 43 as the movable table 30 moves. The side grooves 42, 43 according to this embodiment function as an allowance space that allows the connecting member to move in the Y-axis direction.

[0038] (Drive mechanism) As shown in Fig. 7, the drive mechanism 50 according to this embodiment is a ball screw mechanism disposed in the main groove 41. A screw shaft 52 of the ball screw mechanism is provided in the main groove 41, and rotates about the Y axis in accordance with the rotation of a motor (not shown) under the control of a control panel 70. The motor supports the screw shaft 52, and is provided, for example, in the frame 40. A slider 51 supports the movable table 30, and moves in the Y axis direction while being guided by a pair of linear guides RG in accordance with the rotation of the screw shaft 52 about the Y axis.

[0039] The drive mechanism 50 is not limited to a ball screw mechanism. The drive mechanism 50 is provided on the base 40, and the type thereof is not particularly limited as long as it is capable of moving the movable table 30, and may be, for example, an air cylinder. The air cylinder may be, for example, a cylinder with a rod, a cylinder with a rod and a guide, a rodless cylinder, or a rodless cylinder with a guide.

[0040] (Openable cover member) 9 and 10 are explanatory diagrams for explaining the opening and closing operation of the open-close cover member 60. The open-close cover member 60 is connected to the housing 10 and defines a part of the machining space W. The machining space W according to this embodiment is a space defined by the inner surfaces of the housing 10 (the inner surfaces of the gate-shaped exterior 11 facing the Z1, X1, and X2 directions, the inner surfaces of the gate-shaped exterior 12 facing the Z1, X1, and X2 directions, and the inner surface of the protruding portion 13) and the inner surface of the open-close cover member 60.

[0041] The openable / closable cover member 60 has a lower cover 64, first to third covers 61 to 63 arranged vertically above the lower cover 64, and a gate-shaped frame 60F connected to the housing 10, and is configured to be openable and closable in three directions: the X1 direction, the X2 direction, and the Z2 direction. This means that the direction in which the workpiece is introduced into the machining space W is not limited to a specific direction, and the workpiece can be introduced into the machining space W from other directions, improving the work efficiency and convenience in placing the workpiece on the movable table 30.

[0042] The lower cover 64 is configured to partially enclose the stand 40 and the movable table 30. There are no particular restrictions on the material of the lower cover 64, but for example, a resin material or a metal material is used. Each of the first to third covers 61 to 63 is partially made of a transparent resin material such as acrylic so that an operator of the machining system 1 can see inside the machining space W, and the remaining portion is made of, for example, a resin material or a metal material.

[0043] The first cover 61 is connected to the portal frame 60F via an opening / closing mechanism such as a hinge, and is configured to open and close in the vertical direction around a rotation axis X1 of the opening / closing mechanism as a fulcrum. As shown in Fig. 9, the first cover 61 moves to an open position by rotating vertically upward (in the direction of the dotted arrow in Fig. 9) about the rotation axis X1, and moves to a closed position by rotating vertically downward (in the direction of the solid arrow in Fig. 9) about the rotation axis X1. An operator of the machining system 1 grasps a gripping portion 61G provided on the first cover 61 and pulls the first cover 61 vertically upward to open the first cover 61, and grasps the gripping portion 61G and lowers the first cover 61 vertically downward to close the first cover 61.

[0044] The second and third covers 62, 63 are connected to the portal frame 60F via opening / closing mechanisms such as hinges, and are configured to open and close horizontally around rotation axes X2, X3 of the opening / closing mechanisms as fulcrums. As shown in Fig. 10, the second and third covers 62, 63 move to an open position by rotating in the Y2 direction (the direction of the dotted arrow in Fig. 10) about the rotation axes X2, X3, and move to a closed position by rotating in the X-axis direction (the direction of the solid arrow in Fig. 10) about the rotation axes X2, X3.

[0045] In the open / close cover member 60 according to this embodiment, when all of the first to third covers 61 to 63 are in the closed position, the machining space W is sealed. This prevents machining chips generated when the workpiece is cut from scattering outside the machining space W. On the other hand, when at least one of the first to third covers 61 to 63 is open, the machining space W is opened, and the workpiece can be put in and taken out of the machining space W.

[0046] <Dust collector> The dust collector 200 sucks air from inside and outside the machining space W and removes machining debris contained in the air. Then, the dust collector 200 discharges the air from which the machining debris has been removed into the main groove 41, the side grooves 42 and 43, and the machining space W.

[0047] Specifically, the air inlet 210 of the dust collector 200 sucks air from outside the machining space W via the pipe P1, the hose H7, and the branch pipe P2, and sucks air from inside the machining space W via the exhaust pipe O1, the hose H1, and the branch pipe P2. Furthermore, the air inlet 220 of the dust collector 200 sucks air from inside the machining space W via the exhaust pipe O2, the hose H4, and the branch pipe P4, and sucks air from inside the machining space W via the exhaust pipe O3, the hose H6, and the branch pipe P4.

[0048] As described above, the dust collector 200 removes machining debris contained in the air sucked in through the air inlets 210 and 220. The air outlet 230 of the dust collector 200 then discharges the air from which the machining debris has been removed into the machining space W via the branch pipe P3, the hose H2, the hose H5, the air inlet pipe I1, and the air inlet pipe I3, and further discharges the air into the main groove 41 and the side grooves 42 and 43 via the branch pipe P3, the hose H3, the air inlet pipe I2, and the communication path 44. In this embodiment, from the viewpoint of smoothing the inflow of return air from the exhaust port 230 of the dust collector 200 into the main groove 41, the side grooves 42 and 43, and the machining space W, an adjustment mechanism (e.g., a valve) for adjusting the volume, pressure, etc. of the return air may be provided in, for example, the branch pipe P3, the air inlet pipes I1 to I3, the protruding portion 13, etc.

[0049] The dust collector 200 may be, for example, a gravity dust collector, an inertial force dust collector, a centrifugal force (cyclone) dust collector, a wet dust collector, a filter dust collector, or an electric dust collector, and the type is not particularly limited.

[0050] <Operation panel> The operation panel 70 is an information processing device separate from the machining device 100. The operation panel 70 has a control device, a storage device, a communication device, an input device, and a display device. These are interconnected via a bus. The operation panel 70 is electrically connected to each element that constitutes the machining system 1 (the machining mechanism 20, the drive mechanism 50, and the dust collector 200).

[0051] The control device is composed of one or more processors that control the above-mentioned elements of the machining system 1. For example, the control device is composed of one or more types of processors such as a CPU (Central Processing Unit), an SPU (Sound Processing Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or an ASIC (Application Specific Integrated Circuit).

[0052] In this embodiment, the control device executes a program stored in the storage device to cause the machining system 1 to perform various processes. Examples of such processes include a process of causing the dust collector 200 to discharge air into the main groove 41 and the side grooves 42, 43.

[0053] The storage device is one or more memories that store the programs executed by the control device and the data used by the control device. The storage device is composed of a typical recording medium such as a magnetic recording medium or a semiconductor recording medium. The storage device may also be composed of a combination of multiple types of recording media. The storage device may also be a portable storage medium or an external storage medium that can communicate with the control device.

[0054] The communication device is a communication circuit that is communicatively connected to each element of the machining system 1 described above. The communication device functions as an input / output interface for connecting to each of these elements. The operation panel 70 according to this embodiment may further have a communication interface (not shown) that is connected to a network such as the Internet, and may be connected to an externally connected device such as a server, a personal computer, a smartphone, or a tablet terminal via this network. In this case, various types of data may be exchanged between the operation panel 70 and the externally connected device.

[0055] The input device is a device operated by an operator of the machining system 1, such as a hardware button, switch, touch panel, or lever. The input device may be, for example, a remote control device that uses infrared or other radio waves, or an externally connected device that supports operation of the machining system 1. The input device includes an input control circuit that generates an input signal based on information input by the operator and outputs the signal to the control device. By operating this input device, the operator inputs various parameters into the machining system 1, thereby instructing the machining system 1 to perform various controls and operations. Examples of the parameters include the movement speed of the machining head 21, the movement speed of the movable table 30, and the suction volume and exhaust volume of the dust collector 200.

[0056] The display device is configured as a device capable of notifying the operator of acquired information. The display device is, for example, a display device such as an LCD (Liquid Crystal Display). The display device displays the results obtained by processing by the control device. Specifically, the display device displays, for example, the movement speed of the processing head 21, the movement speed of the movable table 30, and the suction volume and exhaust volume of the dust collector 200.

[0057] [Removal of processing waste] FIG. 11 is an explanatory diagram illustrating how the dust collector 200 removes machining chips. In FIG. 11, the flow of air discharged from the dust collector 200 is indicated by solid and dotted arrows. The dust collector 200 according to this embodiment discharges air from which machining chips have been removed into the main groove 41. Therefore, even if machining chips become mixed in the main groove 41 and the drive mechanism 50, the machining chips are properly removed. Furthermore, in this embodiment, the air discharged into the main groove 41, the side grooves 42 and 43, and the machining space W is return air discharged from the exhaust port 230 of the dust collector 200. This eliminates the need for a separate air supply source, such as a blower, to remove machining chips mixed in the main groove 41 and the drive mechanism 50, thereby reducing the cost of removing machining chips.

[0058] Furthermore, in this embodiment, the dust collector 200 discharges air from which cutting debris has been removed not only into the main groove 41 but also into the side grooves 42 and 43. This removes cutting debris accumulated in the side grooves 42 and 43, and prevents the cutting debris from entering the drive mechanism 50.

[0059] 11, the dust collector 200 according to this embodiment executes a cycle (indicated by the solid arrows in FIG. 11) in which air from which machining debris has been removed is discharged into the main groove 41 and the plurality of side grooves 42, 43, and air containing machining debris is sucked from the machining space W. This constantly maintains a positive pressure state within the main groove 41 and the side grooves 42, 43, making it possible to prevent machining debris removed from the main groove 41 and the side grooves 42, 43 from re-entering the main groove 41 and the side grooves 42, 43.

[0060] 11, in parallel with the above cycle, the dust collector 200 discharges air from which cutting debris has been removed into the space w1 between the rear of the stand 40 in the Y2 direction and the housing 10, the space w2 between the side surface of the stand 40 in the X1 direction and the housing 10 and the third cover 63, and the space w3 between the side surface of the stand 40 in the X2 direction and the housing 10 and the second cover 62, and executes a cycle (the cycle indicated by the dotted arrows in FIG. 11) in which air containing cutting debris is sucked from the spaces w1 to w3. This not only removes cutting debris from the main groove 41 and the side grooves 42, 43, but also removes cutting debris accumulated in the spaces w1 to w3, making it possible to prevent the cutting debris from entering the drive mechanism 50.

[0061] As described above, the machining system 1 according to this embodiment comprises a machining mechanism 20 that machines a workpiece, a movable table 30 that is arranged in the machining space W and faces the machining mechanism 20, and is placed on the workpiece, a stand that is arranged in the machining space W and below the movable table 30, and has a plurality of side grooves 42, 43 that extend in the direction of movement of the movable table 30 and a main groove 41 that extends in that direction of movement and is arranged between one and the other of the plurality of side grooves 42, 43, a drive mechanism 50 that is arranged in the main groove 41 and supports the movable table 30, and moves the movable table 30 in that direction of movement, a machining device 100 that has an openable / closable cover member 60 that defines a part of the machining space W, and a dust collector 200 that sucks in air from inside and outside the machining space W and discharges the air from which machining debris has been removed into the main groove 41.

[0062] According to the above aspect, the dust collector 200 discharges the air from which the machining chips have been removed into the main groove 41. As a result, even if machining chips get mixed into the main groove 41 and the drive mechanism 50, the machining chips are blown away by the discharged air and are properly removed.

[0063] 2. Supplementary Information Although the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to these examples. It is clear that a person skilled in the art to which the present invention pertains can conceive of various modifications and alterations within the scope of the technical ideas set forth in the claims, and it is understood that these also naturally fall within the technical scope of the present invention.

[0064] For example, the machining device 100 illustrated in the above embodiment is an NC router that performs cutting on a workpiece, but is not limited to this. For example, the machining device 100 may be a device that performs grinding on a workpiece, and the use of the present invention is not particularly limited.

[0065] Furthermore, in the above embodiment, the air discharged into the main groove 41, the side grooves 42, 43, and the machining space W is return air discharged from the exhaust port 230 of the dust collector 200, but this is not limited to this. The air discharged into the main groove 41, the side grooves 42, 43, and the machining space W may be air discharged from another air supply source such as a blower. In other words, the device that discharges air into the main groove 41, the side grooves 42, 43, and the machining space W may be an air supply source different from the dust collector, and the device that sucks air from within the machining space W and removes machining chips contained in the air may be the dust collector.

[0066] Furthermore, the effects described in this specification are not limiting. In other words, the present invention may exhibit other effects that will be apparent to those skilled in the art from the description of this specification, in addition to or in place of the above-mentioned effects.

[0067] 3. Notes The following aspects can be understood from the above-described embodiment.

[0068] A machining system according to one aspect (Aspect 1) of the present invention comprises a machining mechanism for machining a workpiece, a movable table arranged in a machining space and facing the machining mechanism, the movable table being placed on the workpiece, a stand arranged in the machining space and below the movable table, the stand having a plurality of side grooves extending in the direction of movement of the movable table and a main groove extending in the direction of movement and arranged between one and the other of the plurality of side grooves, a drive mechanism arranged in the main groove and supporting the movable table, the drive mechanism moving the movable table in the direction of movement, and a machining device having an openable / closable cover member that defines a portion of the machining space, and a dust collector that sucks air from inside and outside the machining space and discharges the air from which machining debris has been removed into the main groove.

[0069] According to the first aspect, the dust collector discharges the air from which the machining debris has been removed into the main groove. As a result, even if machining debris gets mixed into the main groove and the drive mechanism, the machining debris is blown away by the discharged air and is properly removed.

[0070] In the machining system according to a specific example (Aspect 2) of Aspect 1, the dust collector further discharges the air from which the chips have been removed into the plurality of side grooves, thereby removing chips accumulated in the plurality of side grooves and preventing the chips from entering the drive mechanism.

[0071] In a machining system according to a specific example (Aspect 3) of Aspect 2, the dust collector executes a cycle of discharging air from which machining debris has been removed into the main premises and the multiple side gutters, and sucking air containing machining debris from the machining space. This keeps the main gutters and the multiple side gutters in a constant positive pressure state, making it possible to prevent machining debris removed from the main gutters and the multiple side gutters from re-entering the main gutters and the multiple side gutters.

[0072] In a machining system according to a specific example (Aspect 4) of Aspect 3, the openable / closable cover member has a first cover that opens and closes vertically, and second and third covers that open and close horizontally. This means that the direction in which the workpiece is introduced into the machining space is not limited to a specific direction, and the workpiece can be introduced into the machining space from other directions, improving work efficiency and convenience in placing the workpiece on the movable table.
