DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The embodiment will be described with reference to Fig. 1 to Fig. 13(b) First, the overall configuration of a processing apparatus 1000 of the present embodiment will be described with reference to Figs.

[0009] [Processing equipment] FIG. 1 is a front view of a processing apparatus 1000 according to this embodiment connected to a dust collector 300. As shown in FIG. 1, the processing apparatus 1000 accommodates a processing machine 100 (FIG. 2) in an exterior cover 101 serving as a housing. The exterior cover 101 has an opening / closing door 102 as a door through which a processing space 140 (FIG. 9(a) and the like) described below can be accessed, and by opening the opening / closing door 102, it is possible to replace a workpiece or manually replace a tool. The opening / closing door 102 is provided on the front of the processing apparatus 1000 so as to be openable and closable. During processing of a workpiece, the opening / closing door 102 is closed. The opening and closing of the opening / closing door 102 is detected by a sensor (not shown).

[0010] Further, the dust collector 300 collects chips and the like generated by the processing machine 100. For this purpose, the dust collector 300 and the processing device 1000 are connected via a hose 301 and a dust collection duct 110. Although details will be described later, the hose 301 is connected to the dust collector 300 and has flexibility, and the position of the connection side with the dust collection duct 110 can be moved freely to a certain extent. On the other hand, the base end side of the dust collection duct 110 is connected to a dust collection port 131 (see Figs. 8(a) and (b), etc.) provided in the processing device 1000, and the tip side is connected to the hose 301. The dust collection port 131 is formed so as to open to a processing space 140 in which processing is performed by a tool in the processing device 1000. The chips generated in the processing space 140 are collected in the dust collector 300 via the dust collection port 131, the dust collection duct 110, and the hose 301.

[0011] In this embodiment, a plurality of legs 103 are provided on the underside of the exterior cover 101 to support the processing apparatus 1000 and to set it on the installation surface. Therefore, a gap exists between the underside of the exterior cover 101 and the installation surface. As described later, the dust collection duct 110 is provided on the underside of the exterior cover 101 and disposed in the gap between the underside of the exterior cover 101 and the installation surface.

[0012] [Processing machine] FIG. 2 shows the processing machine 100 arranged in the exterior cover 101 of the processing device 1000. In FIG. 2, the storage section 130 (see FIG. 9(a) and (b) etc.) for forming the processing space 140 described later is omitted. The processing machine 100 includes a frame 1 as a moving mechanism support member, a first moving mechanism 10, a second moving mechanism 20, and a third moving mechanism 30 each supported by the frame 1, a support mechanism 40 for supporting a workpiece W as a processing target object, a first rotating mechanism (rotating device) 50 and a second rotating mechanism 60 as rotating means capable of rotating the support mechanism 40, a tool magazine 70, and an electrical unit 80. The first moving mechanism 10, the second moving mechanism 20, and the third moving mechanism 30 constitute a moving device 200 as a moving means for relatively moving a spindle 11 and a holding device 41 described later in three axial directions of X, Y, and Z.

[0013] The frame 1 is placed on a stand 2 having an internal cavity, and as shown in Fig. 2, is composed of a first frame portion 3 and a second frame portion 4 bent at a right angle from an end portion of the first frame portion 3. In this embodiment, the first frame portion 3 is disposed along the vertical direction, and the second frame portion 4 is disposed along the horizontal direction.

[0014] The first moving mechanism 10 is supported on the first surface 3a of the first frame portion 3 of the frame 1 via the second moving mechanism 20, and can move the spindle 11 in the Z-axis direction (vertical direction, first direction). A tool 12 is detachably attached to the spindle 11 via a tool holder (clamp). The spindle 11 is rotationally driven by a motor 13. The first moving mechanism 10 has a motor 14 and a guide shaft (not shown) arranged in the Z-axis direction, and moves the spindle 11 back and forth (up and down) in the Z-axis direction along the guide shaft by driving the motor 14. The spindle 11 is supported movably on the guide shaft via a Z-axis support member (not shown). The guide shaft and the Z-axis support member are covered by a cover 17.

[0015] The second moving mechanism 20 is supported by the first surface 3a of the first frame portion 3 of the frame 1, and is capable of moving the main shaft 11 together with the first moving mechanism 10 in the X-axis direction (horizontal direction, second direction) perpendicular to the Z-axis direction. The second moving mechanism 20 has a motor 21 and a guide shaft (not shown) arranged in the X-axis direction, and is driven by the motor 21 to reciprocate the first moving mechanism 10 in the X-axis direction along the guide shaft.

[0016] The third movement mechanism 30 is supported by the second surface 4a of the second frame portion 4 of the frame 1, and is capable of moving the support mechanism 40 in a Y-axis direction (horizontal direction, third direction) perpendicular to the Z-axis direction and the X-axis direction. The third movement mechanism 30 has a motor (not shown) and a guide shaft (not shown) arranged in the Y-axis direction, and moves the support mechanism 40 back and forth in the Y-axis direction along the guide shaft by driving the motor.

[0017] The third movement mechanism 30 includes a support plate portion 31 that supports the second rotation mechanism 60, and the support plate portion 31 moves back and forth in the Y-axis direction along the guide shaft. As shown in Fig. 2, the support mechanism 40 side of the gantry 2 in the Y-axis direction is open, preventing the support plate portion 31 and the second rotation mechanism supported by the support plate portion 31 from interfering with the gantry 2 even if they move in the Y-axis direction. The third movement mechanism 30 is capable of moving the support mechanism 40 in the Y-axis direction together with the second rotation mechanism 60 and the first rotation mechanism 50, as will be described in detail later.

[0018] The support mechanism 40 supports a workpiece W as a processing object to be machined by the tool 12, such as a dental prosthesis. Such a support mechanism 40 has a holding device 41 that holds the workpiece W, and a support section 42 whose both ends are respectively connected to a rotating section 51 of the first rotating mechanism 50 and that supports the workpiece W via the holding device 41. The holding device 41 and the support section 42 are separate bodies, and as will be described in detail later, the holding device 41 is fixed to the support section 42. However, the holding device 41 and the support section 42 may be integrated.

[0019] The first rotation mechanism 50 can rotate the support mechanism 40 around the a-axis, which is a rotation axis perpendicular to the Z-axis direction. In this embodiment, the a-axis is parallel to the X-axis direction. Such a first rotation mechanism 50 has a support frame 53 that rotatably supports the rotating parts 51 and 52 (see FIG. 3(b)), and a motor that rotates the rotating part 51. The support frame 53 is formed in a substantially U-shape so as to surround the periphery of the support mechanism 40, and is composed of a first support part 53a that supports the motor and the rotating part 51 on one side (driving side), a second support part 53b that supports the rotating part 52 on the other side (driven side), and a connecting part 53c that connects the first support part 53a and the second support part 53b.

[0020] The rotating part 51 supported by the first support part 53a and the rotating part 52 supported by the second support part 53b are arranged to face each other in the a-axis direction and to be rotatable about the a-axis as a rotation axis. Both ends of the support mechanism 40 in the a-axis direction are supported by the rotating parts on both sides. As a result, the first rotation mechanism 50 supports the support mechanism 40 rotatably about the a-axis (X-axis).

[0021] The first rotation mechanism 50 can rotate at least 180° and can turn over the workpiece W supported by the support mechanism 40. In this embodiment, the first rotation mechanism 50 can rotate the support mechanism 40 360° around the a-axis.

[0022] The second rotation mechanism 60 can rotate the support mechanism 40 around the b-axis, which is another rotation axis perpendicular to the Z-axis and a-axis. In this embodiment, the b-axis is parallel to the Y-axis. Such a second rotation mechanism 50 has a rotating unit to which the support frame 53 of the first rotation mechanism 50 is attached, and a motor that rotates the rotating unit. The rotating unit is attached to the connecting portion 53c of the support frame 53, and is rotated by the motor to rotate the support frame 53 around the b-axis. Therefore, the second rotation mechanism 60 supports the support mechanism 40 together with the first rotation mechanism 50 so that the support mechanism 40 can rotate around the b-axis (Y-axis). The above-mentioned moving mechanism, support mechanism, and rotating mechanism may be realized with other structures as long as they can perform their respective roles.

[0023] The tool magazine 70 as a tool holding section can store a plurality of tools, is disposed adjacent to the first rotating mechanism 50, and is supported by a support member, which is supported by the support plate section 31 of the third moving mechanism 30. Therefore, the tool magazine 70 can be moved in the Y-axis direction together with the support mechanism 40 and the like by the third moving mechanism 30. However, even if the support mechanism 40 rotates around the a-axis, the tool magazine 70 does not rotate, and even if the support mechanism 40 rotates around the b-axis, the tool magazine 70 does not rotate. In other words, the tool magazine 70 is supported by the support plate section 31 so as to maintain a predetermined posture even if the support mechanism 40 rotates around the a-axis and the b-axis. The tool magazine 70 can be moved in the Y-axis direction together with the support mechanism 40 and the like by the third moving mechanism 30.

[0024] In the tool magazine 70, a plurality of types of tools each formed integrally with the tool holder 12a are held and arranged in a plurality of rows along the Y-axis direction. The tools attached to the spindle 11 are replaceable. The tools may be replaced by an operator or automatically by the processing machine 100. In this embodiment, in order to automatically replace the tools, the spindle 11 is configured to automatically grip and release the tools.

[0025] When the tool is automatically replaced, the second moving mechanism 20 and the third moving mechanism 30 move the empty space of the tool magazine 70 where no tool is inserted to below the spindle 11. In other words, the spindle 11 is moved relative to the tool magazine 70 on the XY plane. Then, the first moving mechanism 10 lowers the spindle 11 (moves it in the Z-axis direction), and an attachment / detachment device such as a chuck provided on the spindle 11 is operated to remove the tool 12 attached to the spindle 11 and place it in the empty space of the tool magazine 70. Next, the first moving mechanism 10 raises the spindle 11, and the second moving mechanism 20 and the third moving mechanism 30 move the position of the tool magazine 70 where the tool 12 to be replaced is located to below the spindle 11. Then, the first moving mechanism 10 lowers the spindle 11 again, and the attachment / detachment device is operated to mount the tool 12 to be replaced on the spindle 11. The tool 12 is, for example, a drill or an end mill.

[0026] In this embodiment, before and after storing or removing the tool, the tip of the tool 12 is brought into contact with a tool length sensor (touch sensor) 96, which serves as tip detection means capable of detecting the tip of the tool 12 held by the spindle 11, to check whether the tool 12 is held by the spindle 11. At this time, the center (a-axis) of the workpiece in the Z direction is aligned with the tip of the tool. The tool length sensor 96 is provided at a position adjacent to the tool magazine 70, as shown in FIG. 2. Particularly, in this embodiment, the tool length sensor 96 is disposed on the second support portion 53b that supports the driven-side rotating portion 52.

[0027] The electrical equipment unit 80 is attached to the inside of the frame 1. That is, the electrical equipment unit 80 is disposed on the opposite side of the first surface 3a of the first frame portion 3 and the opposite side of the second surface 4a of the second frame portion 4. Such an electrical equipment unit 80 controls the processing machine 100, and includes a control board that controls the drive of the motors of the main shaft and each shaft, and a plurality of control units that calculate pulses to be output to the motors from signals of the rotary encoders of the respective corresponding motors and appropriately control the rotation of the respective corresponding motors.

[0028] Moreover, the processing machine 100 of this embodiment is an NC processing device that performs automatic processing under computer control. Specifically, processing data is created by a CAD / CAM system using an external terminal such as a personal computer, and the workpiece W is processed by numerical control based on this data. For this purpose, an external terminal such as a personal computer that issues commands to the processing machine 100 is connected to the control board of the processing machine 100. The external terminal may create NC code according to conditions and send it to the control board. Note that the processing machine 100 itself may be provided with a computer equipped with a CPU and memory capable of numerical control.

[0029] For example, when a dental prosthesis is to be created by the processing machine 100, data of the dental prosthesis measured by a three-dimensional measuring device is transferred to a CAD / CAM system, and processing data is created by the CAD / CAM system. Then, based on this processing data, the processing machine 100 is controlled to cut the workpiece W with the tool 12, thereby creating the dental prosthesis.

[0030] [Air blowing] Next, the air blowing configuration of the machining apparatus 1000 of this embodiment will be described with reference to Figures 3(a) and 4. In this embodiment, the spindle 11 is provided with an air blowing unit 87 (see Figure 4(a) etc.) that blows air toward a tool attached to the tip of the spindle 11. In this embodiment, as described later, the air blowing unit 87 is used to blow air toward the holding device 41, thereby removing chips adhering to the holding device 41. In other words, the air blowing unit 87 is capable of blowing air toward the holding device 41.

[0031] 3(a) and 3(b), during the cleaning operation in which the air blow unit 87 blows air onto the holding device 41, the holding device 41 is tilted with respect to the horizontal direction by the second rotation mechanism 60 as a rotating device. In this embodiment, the holding device 41 is tilted so that the side opposite to the tool magazine 70 arranged adjacent to the holding device 41 is lower, in other words, so that the tool magazine 70 side is higher. The tilt angle is, for example, 20° with respect to the horizontal direction. The tilt angle here refers to a state in which the surface of the holding device 41 or the surface of the workpiece W is parallel to the XY plane, that is, an angle tilted about the Y axis from a horizontal state. Depending on the configuration of the device, the holding device 41 may be tilted about the X axis from a horizontal state. The cleaning operation will be described later.

[0032] The air blow unit 87 will be described with reference to Figs. 4(a) and (b). Fig. 4(a) is a perspective view of the spindle 11 from the side (tip side) where the tool is attached. The air blow unit 87 has a plurality of (four in this embodiment) air outlets (blowout ports) 121 around the chuck portion 11a where the tool is attached, on the tip side of the spindle 11. The spindle 11 is also provided with an air inlet 122 connected to a compressor (not shown), and when compressed air is sent from the air inlet 122, air is blown from the four air outlets 121 toward the tool provided at the tip of the spindle 11. This cools the tool and removes chips attached to the tool. The four air outlets 121 allow air to be applied to the entire tool. Of course, there may be more than four air outlets 121.

[0033] FIG. 4(b) is a cross-sectional view of the air outlet 121 of the air blow unit 87. The air blow unit 87 has a communication port 123 connected to the air inlet 122, a nozzle 124 formed downstream of the communication port 123 in the air flow direction and having a smaller cross-sectional area than the communication port 123, and an air outlet 121 formed at the tip of the nozzle 124. These are formed in the spindle 11. The nozzle 124 is inclined toward the tool attached to the spindle 11 as it moves downstream in the air flow direction. As a result, air flowing in from the air inlet 122 passes through the communication port 123 and the nozzle 124 and is blown out from the air outlet 121. Since the nozzle 124 is thinner than the communication port 123, the flow rate of the air blown out from the air outlet 121 can be increased. In addition, since the nozzle 124 is inclined toward the tool, air can be blown out from the air outlet 121 toward the tool. In addition, since the blower port 121 is formed in a partial cone shape so that the cross-sectional area increases from the nozzle 124 toward the tip, the blower port 121 can be easily processed.

[0034] [Control configuration of processing equipment] Next, the control configuration of the machining device 1000 will be described with reference to Fig. 5. As shown in Fig. 5, the electrical equipment unit 80 includes a CPU 85 as a calculation means, an input / output port (I / O) 86i, control units 84x, 84y, and 84z of the motors, a control unit 84c of the spindle 11, a control unit 84a of the a-axis, and a control unit 84b of the b-axis. The CPU 85 provided on the control board of the electrical equipment unit 80 performs various calculations using a memory 86m based on input data and signals, and transmits instructions on rotation speed and position to the control units 84x, 84y, 84z, 84a, 84b, and 84c as connected servo amplifiers.

[0035] The I / O 86i is connected to the compressor 350, the dust collector 300, and the tool length sensor 96 of the processing machine 100. The compressor 350 supplies compressed air to the air blow unit 87, which blows air onto the tool as described above, and the removed chips are collected by the dust collector 300. The tool length sensor 96 detects the length of the tool and sends a signal to the CPU 85.

[0036] The control units 84x, 84y, and 84z of each motor drive the X, Y, and Z motors based on commands from the CPU 85. The control units 84x, 84y, and 84z of each motor are provided with encoders. The encoders detect, for example, the number of rotations, the rotation angle, and the rotation direction of the rotation shaft of the control units 84x, 84y, and 84z of each motor. Then, they detect the amount (position) of movement of each stage x, y, and z by the drive of the control units 84x, 84y, and 84z of each motor.

[0037] The control unit 84c controls a motor (not shown) that rotates the main shaft 11 to control the rotation speed of the main shaft (spindle). In addition, the a-axis and b-axis control units 84a and 84b drive the a-axis and b-axis motors based on commands from the CPU 85.

[0038] The control unit 84a controls the motor 54 of the first rotation mechanism 50 to rotate the support mechanism 40 around the a-axis. The control unit 84b controls the motor of the second rotation mechanism 60 to tilt the support mechanism 40 around the b-axis, and determines the attitude of the support mechanism 40. The control unit 84x also controls the motor 21 of the second movement mechanism 20 to move the spindle 11 in the X-axis direction, and determines the position of the spindle 11 in the X-axis direction. The control unit 84y controls the motor of the third movement mechanism 30 to move the support mechanism 40 in the Y-axis direction, and determines the position of the support mechanism 40 in the Y-axis direction. The control unit 84z controls the motor 13 of the first movement mechanism 10 to move the spindle 11 in the Z-axis direction, and determines the position of the spindle 11 in the Z-axis direction. This determines the relative positions of the spindle 11 and the support mechanism 40 in the X-axis, Y-axis, and Z-axis directions. In this manner, the CPU 85 controls each part of the machining apparatus 1000, whereby a predetermined machining is performed on the workpiece W held by the holding device 41 of the support mechanism 40 as described above.

[0039] [Holding device] Here, the holding device 41 of this embodiment has an approximately C-shape as shown in FIG. 3(b). This is to allow the processing object (workpiece) to be processed even when tilted 90° around the a-axis (X-axis), and the holding device 41 has a C-shape with the front side open in FIG. 3(a). That is, the holding device 41 that holds the workpiece W includes a pair of arm parts 41a and a connecting part 41b. The pair of arm parts 41a are arranged to sandwich the workpiece W from both sides. The connecting part 41b connects one end of the pair of arm parts 41a to each other and is formed integrally with the pair of arm parts 41a. On the other hand, the other end side of the pair of arm parts 41a is not connected, and as a result, the holding device 41 is formed in an approximately C-shape.

[0040] The holding device 41 has a resin part 410 as a resin main body, a metal plate 420 as a first reinforcing plate, a metal plate 430 as a second reinforcing plate, and a holding cover 440 as a holding member. The holding device 41 is configured by connecting these with a plurality of bolts 420a, 440a, etc. Specifically, the resin part 410 is sandwiched between a pair of metal plates 420, 430, and the pair of metal plates 420, 430 are fixed to the resin part 410 with bolts. In this state, the work W on the disk is placed on the work W, and the holding cover 440 is pressed down on the work W, and the holding cover 440 is fixed to the resin part 410 via the metal plate 420 with bolts. Such bolts are fixed and removed by rotating them with a wrench or the like. Note that other fastening methods may be used in addition to fastening with such bolts.

[0041] In any case, fasteners such as a plurality of bolts 420a, 440a are exposed on the surface of the holding device 41, and chips generated when the workpiece W is machined by a tool tend to remain around the bolts 420a, 440a. If chips accumulate in this manner, it is difficult to rotate the bolts with a tool such as a wrench when attaching or detaching the workpiece. Therefore, in this embodiment, the following cleaning operation can be performed.

[0042] [Cleaning action] The cleaning operation of the holding device 41 of this embodiment will be described with reference to Figs. 6 to 7 while also referring to Figs. 3(a) and 4. As shown in Figs. 3(a) and (b) above, during the cleaning operation, the motor of the second rotation mechanism 60 is controlled to rotate the support mechanism 40 about the b-axis by 20° with respect to the horizontal direction. Then, with the attitude of the support mechanism 40 inclined, the spindle 11 is moved while blowing air.

[0043] The blowing of air in the cleaning operation is performed by moving the main shaft 11 so that it passes over the multiple bolts 420a and 440a, which are fixing devices, in that order. Note that, as long as the air is moved so that it hits each bolt, it does not necessarily have to pass over each bolt. Specifically, the air is blown in the order of the arrows shown in FIG. 6. Here, the holding device 41 of the support mechanism 40 is inclined with respect to the horizontal direction so that the right side of FIG. 6 is higher. Also, in FIG. 6, the bolts at positions P1, P4, P5, and P8 are bolts 440a for fixing the holding cover 440 for pressing down and holding the workpiece W to the resin part 410 via the sheet metal 420. Also, the bolts at positions P2, P3, P6, and P7 are bolts 420a for fixing the sheet metal 420 to the resin part 410.

[0044] The main shaft 11 moves relative to the holding device 41 so that the position of the air blown from the air blow unit 87 is first between positions P1 and P2, then between positions P3, P4, P5, P6, and between positions P7 and P8 in that order. The relative movement of the main shaft 11 and the holding device 41 is performed by the above-mentioned first moving mechanism 10, second moving mechanism 20, and third moving mechanism 30 as moving devices. When the main shaft 11 is not moved in the Z-axis direction during the cleaning operation, the main shaft 11 and the holding device 41 may be moved relative to each other by the second moving mechanism 20 and the third moving mechanism 30.

[0045] As described above, the holding device 41 is inclined so that the right side in FIG. 6 is higher, so that the positions P1 to P4 on the right side in FIG. 6 are higher than the positions P5 to P8 on the left side. Therefore, the spindle 11 and the holding device 41 move relative to each other so that the air blowing unit 87 blows air from the upper side to the lower side of the tilted holding device 41 during the cleaning operation. By blowing air in such an order, the air is blown from an oblique upward direction to a downward direction against the chips adhering to the surface of the holding device 41, so that the chips can be removed efficiently. In particular, the bolts 420a and 440a are parts that protrude from the surface of the holding device 41, and chips are difficult to fall off. However, by tilting the holding device 41 with respect to the horizontal direction and blowing air from the upper side to the lower side in order as described above, even chips that are difficult to fall off can be efficiently removed.

[0046] However, the order in which the air is blown is not limited to this. For example, in the above example, the distance between positions P1 and P2, and the distance between positions P7 and P8 are close to each other, so by blowing air toward these positions, the chips at both positions can be removed, but if the distance is far, air may be blown toward each position. Also, with regard to positions P3 to P6, if the positions of adjacent bolts are close to each other, air may be blown between the bolts that are close to each other.

[0047] In addition, the order of blowing air is first from the bottom to the top of the inclined holding device 41 on the opening side opposite to the connecting portion 41b of the holding device 41. Then, it may be blown from the top to the bottom of the connecting portion 41b. For example, the order is positions P7, P8, P1, P2, P3, P4, P5, and P6. In this way, when air is blown from the bottom to the top at the opening side of the C-shaped holding device 41, that is, at the portion where there is no connecting portion, the chips tend to fall through the opening of the holding device 41, so even if air is blown from the bottom to the top, the chips can be efficiently removed. And, by blowing air from the top to the bottom on the connecting portion 41b side, the chips tend to fall along the inclination, so that the chips can be efficiently removed. In this order as well as the order shown in FIG. 6, the main shaft 11 can be moved in a substantially circular manner while always applying air to the surface of the holding device 41, so that the cleaning work can be efficiently performed.

[0048] An example of the flow of such a cleaning operation will be described with reference to the flowchart in Fig. 7. In this embodiment, the cleaning operation (cleaning mode) is executed by the CPU 85 by loading a program into a storage means such as the memory 86m. When the cleaning mode is executed during machining, first, the current coordinate position is stored in the memory 86m as a return coordinate position (S1). That is, in order to execute the cleaning mode during machining, the position is saved in order to return to the original machining position after the cleaning mode is completed.

[0049] Next, the spindle 11 is raised in the Z-axis direction and withdrawn from the holding device 41 (S2). At this time, the rotation of the spindle 11 is stopped (S3). Next, the tool held by the spindle 11 is stored in the tool magazine 70 (S4). After the tool is stored, the spindle 11 is raised again (S5). Next, the second rotation mechanism 60 is driven to rotate the holding device 41 about the b-axis (Y-axis) and tilt it with respect to the horizontal direction (S6). The angle is, for example, 20° with respect to the horizontal direction as described above, but may be another angle.

[0050] In this state, the spindle 11 and the holding device 41 are moved relatively in the X-axis and Y-axis directions to the midpoint between positions P1 and P2 shown in Fig. 6 (S7). As described above, the distance between positions P1 and P2 is short, and air can be applied simultaneously, so this is the midpoint position here. Next, the spindle 11 is lowered in the Z-axis direction (S8). This position becomes the standby position before air is applied.

[0051] Then, the air blowing unit 87 starts blowing air (S9). At this time, the air flow rate is maximized and the nozzle 124 of the air blowing unit 87 is used to blow air, generating a strong air blow and making it easier to blow away chips. Next, the spindle 11 is moved to position P3 while blowing air, and remains at that position for a predetermined time (S10). After that, the spindle 11 is moved while blowing air in the order shown by the arrows in FIG. 6, and remains at that position for a predetermined time. That is, the spindle 11 is moved in sequence to position P4 (S11), position P5 (S12), position P6 (S13), and the midpoint position between positions P7 and P8 (S14), stopping at each position for a predetermined time, and then moving to the next position.

[0052] For steps S10 to S14, not only is movement performed in the XY directions, but movement is also performed in the Z direction following the inclination angle of the holding device 41 so as to maintain a constant distance between the air outlet 121 (nozzle tip) of the air blow unit 87 and the holding device 41. In other words, when the holding device 41 is inclined and tilted downward to the left in Fig. 3(a), the nozzle tip position is gradually lowered downward in accordance with the inclination angle of the holding device 41 as it approaches the left side.

[0053] When air blowing is completed up to the midpoint between positions P7 and P8, the air blowing by the air blow unit 87 is stopped (S15). Then, the spindle 11 is raised in the Z-axis direction and moved away from the holding device 41 (S16). Thereafter, the holding device 41 is returned to the horizontal direction (S17). The reason for raising the spindle 11 and returning the holding device 41 to the horizontal direction in this manner is to prevent interference between the spindle 11 and other members.

[0054] Next, the tool stored in the tool magazine 70 in S4 is removed (S18). That is, the tool that was used is chucked by the spindle 11 again. Next, the spindle 11 is rotated (S19), and the spindle 11 and the holding device 41 are moved relatively to the return position stored in S1 (S20). Then, the interrupted machining operation is resumed. Air can be efficiently blown onto the bolt position exposed on the surface of the holding device 41, reducing chips that accumulate in that area and reducing the effort of cleaning by the user after machining is completed.

[0055] Here, in this embodiment, the direction in which the holding device 41 is tilted in the cleaning mode is the direction in which the side opposite the tool magazine 70 is downward. This is to allow chips to fly to the side opposite the tool magazine 70. For example, if the holding device 41 is located in the center of the machining chamber and the tool magazine 70 is located on the right side, by tilting the holding device 41 downward and to the left, chips will fly to the left when air is thrust against the holding device 41, and therefore accumulation of chips on the tool magazine 70 can be suppressed.

[0056] Moreover, if the holding device 41 is tilted in this way so that the side opposite to the tool magazine 70 is downward, in other words so that the tool magazine 70 side is upward, the second support part 53b of the first rotating mechanism 50 becomes a shield between the holding device 41 and the tool magazine 70, and chips are less likely to fly to the tool magazine 70. The tilt direction of the holding device 41 in the cleaning mode is preferably a direction in which at least a part of the support mechanism and the rotating mechanism becomes a shield against the tool magazine, like the second support part 53b, and the tilt angle is preferably 5° to 45° with respect to the horizontal direction. In particular, it is preferable to tilt the holding device 41 so that the part of the tool held by the spindle 11 of the tool placed in the tool magazine 70 is hidden by the shield when viewed from the horizontal direction (X direction).

[0057] In the above embodiment, the cleaning mode is performed with the holding device 41 rotated and tilted around the b axis, but the cleaning operation may be performed with the holding device 41 rotated and tilted about another rotation axis. When the tool magazine is not in the machining chamber, the cleaning mode may be performed with the holding device 41 tilted as described above, or the cleaning mode may be performed with the holding device 41 tilted in another direction or about another rotation axis. By tilting the holding device 41 from the horizontal direction when the cleaning mode is performed, for example, the user can easily remove chips attached to the holding device 41 with a brush or the like during finishing.

[0058] In addition, in the above-mentioned cleaning mode, air may be blown toward the tools stored in the tool magazine 70, and then the plurality of bolts 420a, 440a of the holding device 41, or air may be blown toward the tools stored in the tool magazine 70 after the plurality of bolts 420a, 440a are blown. In either case, if air is blown toward the plurality of bolts 420a, 440a, chips are less likely to be caught when the plurality of bolts 420a, 440a are attached or detached. In addition, in the cleaning mode, air may be blown toward at least one of the plurality of bolts 420a, 440a while the holding device 41 is rotated and tilted. That is, the cleaning mode may be performed at any timing as long as chips are less likely to be caught in the plurality of bolts 420a, 440a.

[0059] For example, the timing for executing the above-mentioned cleaning mode may be any timing determined by the user, or may be a predetermined timing such as the end of processing. When the material of the workpiece is resin, it is particularly preferable to execute the cleaning mode. This is because resin is easily clumped together by static electricity and is difficult to remove afterwards. For example, the cleaning mode may be executed multiple times during processing of one workpiece. In addition, when multiple processing modes exist for processing one workpiece, the cleaning mode may be executed for each processing mode or multiple times in one processing mode. In addition, although there have been configurations in which a static eliminator was provided for this purpose in the past, such a static eliminator can be omitted by executing the cleaning mode as in this embodiment.

[0060] On the other hand, when the workpiece is made of a material other than resin, such as zirconia, the frequency of the cleaning mode may be lower than when the workpiece is made of resin. This is because the cleaning mode takes a certain amount of time, and frequent execution of the cleaning mode reduces productivity. Therefore, when the workpiece is made of a material other than resin, it is preferable to reduce the frequency of execution of the cleaning mode, for example, by executing the cleaning mode only at the end of processing. Note that the frequency of execution of the cleaning mode may be selectable depending on the type of workpiece.

[0061] By executing the cleaning mode at any timing or a predetermined timing as described above, it is possible to prevent chips from accumulating too much on the holding device 41. In addition, by tilting the holding device 41 and blowing air onto it, chips can be efficiently removed in each cleaning mode.

[0062] In this embodiment, in a processing apparatus that fixes a workpiece with fasteners such as bolts and rotates a holding device 41 that holds the workpiece to perform processing, chips can be removed efficiently in a simple manner by executing a cleaning mode on the fastener with the holding device 41 tilted. This makes it easy to reduce the amount of chips that accumulate before the workpiece is attached or detached. Such a cleaning mode may be incorporated into an existing processing apparatus having the above-mentioned configuration as a control method or program for the processing system.

[0063] [Cutting dust collection] Next, a configuration for collecting chips blown off in the cleaning mode or chips generated during processing as described above will be described with reference to FIG. 1 and with reference to FIG. 8(a) to FIG. 13(b). As shown in FIG. 1, the processing device 1000 of this embodiment is connected to the dust collector 300. The processing device 1000 and the dust collector 300 are connected via a hose 301 and a dust collection duct 110. The dust collector 300 is driven at least during processing operation to collect chips generated during processing operation. It is also driven when the above-mentioned cleaning mode is executed. However, when the operation of the dust collector 300 is not linked to the operation of the processing device 1000 and is driven separately by the operation of the operator, the operator may operate the dust collector 300 as appropriate.

[0064] The processing device 1000 has a processing machine 100 and an exterior cover 101 that houses the processing machine 100. As shown in FIG. 8(a) to FIG. 9(b), the processing machine 100 has a storage section 130 that houses the spindle 11, the holding device 41, the tool magazine 70, etc., and forms a processing space 140 in which processing is performed by the tools. In this embodiment, a dust collection port 131 to which the dust collection duct 110 is connected is provided on a bottom surface 132 of the storage section 130. That is, in this embodiment, the dust collection port 131 is provided on the bottom surface 132 in the vertical direction, not on the back side of the device. The dust collection port 131 is configured by drilling multiple holes in a metal plate, but may be in the form of a mesh. This prevents tools, bolts, etc. from entering the dust collection port 131 even if they fall to the bottom surface 132.

[0065] The dust collection port 131 is provided at a position where it at least partially overlaps with the holding device 41 at the home position when viewed vertically. The home position of the holding device 41 is the position where the holding device 41 is located in the XY direction when processing starts, and is the origin position to which the holding device 41 returns when processing ends or is interrupted. In this embodiment, when the storage section 130 is viewed vertically, the home position is a position that is approximately the center in the X-axis direction and is in front of the center in the Y-axis direction. Figures 8(a) and (b) show a state where the holding device 41 is located at the home position in the XY direction, and the dust collection port 131 is formed almost directly below the holding device 41 at the home position.

[0066] The position of the dust collection port 131 does not have to be directly below the holding device 41, and may be shifted to the front, back, left or right as long as it is below the holding device 41. However, in order to efficiently collect chips and the like generated by machining the workpiece held by the holding device 41, it is preferable to provide the dust collection port 131 at a position where at least a part of it overlaps with the holding device 41 at the home position when viewed vertically.

[0067] In this embodiment, the bottom surface 132 of the storage section 130 in which the dust collection port 131 is formed is provided with inclined surfaces 133 and 134 that slope downward from the end of the storage section 130 toward the dust collection port 131. First, as shown in Figures 8(a) and (b), the inclined surface 133 is provided below the tool magazine 70 so as to slope downward from the right side wall 130a of the storage section 130 toward the dust collection port 131.

[0068] FIG. 8(a) is a diagram showing a case where the holding device 41 is inclined to the maximum so that the tool magazine 70 side of the holding device 41 is higher. FIG. 8(b) is a diagram showing a case where the holding device 41 is inclined to the maximum so that the tool magazine 70 side of the holding device 41 is lower. The inclined surface 133 is formed so as not to interfere with the holding device 41 in either state. Since chips may accumulate in a lump at the bottom of the tool magazine 70 located in the machining space 140, the inclined surface 133 is provided below the tool magazine 70. By providing the inclined surface 133 only on one side in the left-right direction (X-axis direction) of the storage section 130, the machining space 140 can be effectively utilized, the device can be made smaller, and the chips can be easily moved toward the dust collection port 131.

[0069] In this embodiment, as shown in Fig. 10, an inclined surface 134 is also provided on the front side of the storage unit 130. Fig. 10 is a perspective view of the storage unit 130 as seen from the rear side, with a cylinder including a circle B inserted and cut. Therefore, the front left side in Fig. 10 is the rear side, and the rear right side is the front side. The inclined surface 134 is provided so as to incline downward from the front wall 130b of the storage unit 130 toward the dust collection port 131.

[0070] An opening 141 that allows access to the machining space 140 when the opening / closing door 102 (see FIG. 1) of the exterior cover 101 is opened is formed in the front wall 130b, and the inclined surface 134 is provided below the opening 141. The inclined surface 134 is also formed so as not to interfere with the holding device 41 in either state shown in FIG. 8(a) or (b). By providing the inclined surface 134 on only one side in the front-to-rear direction (Y-axis direction) of the storage section 130, the machining space 140 can be effectively utilized, the device can be made more compact, and cutting chips can be easily moved toward the dust collection port 131.

[0071] Next, the dust collection duct 110 connected to the dust collection port 131 will be described. The dust collection duct 110 is provided so that the position of the connection port 111 connected to the hose 301 of the dust collector 300 can be switched to either the left or right direction when the exterior cover 101 as a housing is viewed from the front. Specifically, as shown in FIG. 1, the dust collection duct 110 is provided so that it is located in either the left or right direction when the exterior cover 101 is viewed from the front, and at least the connection port 111 connected to the hose 301 of the dust collector 300 protrudes from the exterior cover 101 when viewed from above. That is, as shown in FIG. 1, the dust collection duct 110 is disposed in a gap between the bottom surface of the exterior cover 101 formed by the multiple legs 103 and the installation surface. The dust collection duct 110 can be attached to the storage section 130 by changing the direction in which it protrudes from the exterior cover 101, as shown in FIGS. 9(a) and 9(b). As shown in FIG. 12, dust collection duct 110 is provided in storage section 130 such that the tip side of dust collection duct 110 including connection port 111 protrudes beyond exterior cover 101 when viewed from above.

[0072] In this embodiment, as shown in FIG. 11, the dust collection duct 110 is fixed to the lower surface of the storage section 130 by a plurality of screws 142. The base end of the dust collection duct 110 is provided with a flange 113 around a cover section 112 that opens upward so as to cover the entire dust collection port 131, and the flange 113 and the lower surface of the storage section 130 are fastened with a plurality of screws 142, so that the dust collection duct 110 is fixed to the lower surface of the storage section 130. That is, the cover section 112 as a receiving section is connected to the bottom surface 132 of the storage section 130. The cover section 112 and the flange 113 are formed so as to be symmetrical with respect to an imaginary line that passes through the center in the front-rear direction and is parallel to the left-right direction, so that even if the mounting direction is reversed, the cover section 112 can cover the dust collection port 131, and the positions of the screw holes of the flange 113 (mounting section) and the screw holes provided on the lower surface of the storage section 130 match.

[0073] Also, a mechanism for varying the length of the duct portion 114 may be used, and the connection port 111 may be attached to protrude to the front or rear, and the position of the connection port 111 may be adjusted to a position where the hose can be easily connected. That is, when the processing device 1000 is viewed from the front, the position of the connection port 111 protruding from the exterior cover 101 can be switched not only left and right but also front and rear. The arrangement of the screw fastening parts of the flange 113 is square, and the flange 113 can be attached even if rotated 90° at a time. When the duct is attached to extend to the front and rear sides, the position may be adjusted as a mechanism for varying the length of the duct portion 114. Also, the position of the connection port 111 protruding from the exterior cover 101 may be any position around the exterior cover 101. In this case, the shape of the flange 113 may be, for example, circular, and the position of the screw fastening part may be point symmetrical with respect to the center of the opening on the dust collection port 131 side of the cover portion 112, so that the protruding direction of the connection port 111 can be set to any position around the center of the dust collection port 131.

[0074] 9(a) is a diagram showing the dust collection duct 110 disposed so as to protrude to the left side as viewed from the front, and FIG. 9(b) is a diagram showing the dust collection duct 110 disposed so as to protrude to the right side as viewed from the front. In either case, the dust collection duct 110 is fixed to the housing 130 so that the connection port 111 provided on the tip side of the dust collection duct 110 protrudes beyond the exterior cover 101. Note that the dust collection duct 110 may be fixed to the housing 130 so as to be rotatable about the Z-axis direction, regardless of the fixing method as described above. In this case, for example, the dust collection duct 110 is rotated in a state where the leg 103 in the direction in which the dust collection duct 110 is rotated is removed.

[0075] 9(a) and (b), the storage section 130 is open at the top so that the main shaft 11 can be moved in the X-axis direction by the second moving mechanism 20 (FIG. 2), and roll curtains 135a and 135b are provided to close the gap between this opening and the main shaft 11. The roll curtains 135a and 135b are arranged on both sides of the main shaft 11 in the X-axis direction (longitudinal direction) and are linked to the movement of the main shaft 11 in the X-axis direction. Specifically, the ends of the roll curtains 135a and 135b on the main shaft 11 side are connected to the main shaft 11, and the opposite ends are connected to winding sections 136a and 136b that can wind and pull out the roll curtains 135a and 135b. Furthermore, at both ends of the roll curtains 135a, 135b in the Y-axis direction (width direction) at positions that do not interfere with the main shaft 11, pressing portions 137a, 137b made of, for example, metal plates are provided to prevent the roll curtains 135a, 135b from floating.

[0076] When the main shaft 11 moves in one direction in the X-axis direction, the roll curtains 135a, 135b on one side are wound up on the winding section, and the roll curtains on the other side are pulled out from the winding section. At this time, both ends in the width direction are held down by the holding sections 137a, 137b, and this action can prevent a gap from being generated between the roll curtains 135a, 135b and the opening of the storage section 130. By providing the roll curtains 135a, 135b at the moving points of the main shaft 11 in this way, it is possible to prevent chips generated by machining from scattering to the outside from the main shaft 11 side of the storage section 130.

[0077] The material of the roll curtains 135a and 135b is a resin such as PET (polyethylene terephthalate). The roll curtains 135a and 135b are made of a transparent film containing an antistatic material. If the roll curtains 135a and 135b are transparent, the inside of the processing chamber can be seen from above, making it easy to grasp the processing state.

[0078] The dust collection duct 110 has a cover portion 112 on the base end side, a connection port 111 provided on the tip end side, and a duct portion 114 that communicates the connection port 111 and the cover portion 112. As shown in FIG. 11, the cover portion 112 has a rectangular shape that is open at the top, and the duct portion 114 is provided on the side of the cover portion 112 so as to communicate with the space inside the cover portion 112. The duct portion 114 is formed in a rectangular parallelepiped shape that is narrower than the width of the cover portion 112 in the front-rear direction and is also narrow in the height direction. The connection port 111 is provided on both the front and rear sides of the tip end of the duct portion 114, and opens to the front and rear sides, respectively. That is, in this embodiment, the dust collection duct 110 is provided with two connection ports 111 that face in different directions.

[0079] When connecting the hose 301 of the dust collector 300, the hose 301 is connected to either one of the front and rear connection ports 111, and the other connection port 111 is blocked by a blocking member 115 such as a rubber plug. For example, in Figs. 9(a), (b) and 11, the rear connection port 111 is blocked by the blocking member 115, and the hose 310 is connected to the front connection port 111. The front and rear connection ports 111 have the same shape and can be blocked by a common blocking member 115, and a common hose 301 can be connected to them. Therefore, when connecting the hose 301 to the rear connection port 111, the front connection port 111 is blocked by the blocking member 115.

[0080] It is also possible to provide two or more connection ports 111. For example, in addition to the front and rear, connection ports 111 may also be provided on the left and right end surfaces so as to open in the protruding direction (left or right) of dust collection duct 110.

[0081] 9(a) and (b) are cross-sectional views in which the dust collection duct 110 is connected to the lower surface of the storage section 130. The dust collection duct 110 is fixed to the lower surface of the storage section 130 via the flange 113 so that the cover section 112 covers the entire dust collection port 131 with an opening formed on the upper side. The duct section 114 is disposed in a substantially horizontal direction so that the upper surface is shifted downward from the flange 113. This prevents the upper surface of the duct section 114 from interfering with the lower surface of the storage section 130 when the flange 113 is fixed to the lower surface of the storage section 130. The lower surface of the duct section 114 is at substantially the same height as the lower surface of the cover section 112. The connection port 111 is provided at the tip of the duct section 114, and is provided so that its lower end is located above the lower surface of the duct section 114. This prevents the hose 301 from interfering with the installation surface when the hose 301 is connected, thereby preventing excessive force from being applied to the connection port 111. In this manner, in this embodiment, when the dust collection duct 110 is provided on the lower surface of the storage portion 130, the vertical positional relationship between the cover portion 112, the duct portion 114, and the connection port 111 is appropriately regulated.

[0082] According to the present embodiment as described above, the dust collection duct 110 and the hose 301 of the dust collector 300 can be easily connected regardless of the positional relationship between the processing device 1000 and the dust collector 300. That is, in the present embodiment, the dust collection duct 110 connected to the dust collection port 131 is provided on the lower surface of the storage section 130, and the tip portion including the connection port 111 of the dust collection duct 110 is made to protrude outside beyond the exterior cover 101. At this time, the entire connection port 111 is made to protrude outside, but by making at least a part of the connection port 111 protrude outside, it is possible to easily connect the hose 301 and the connection port 111. In addition, the dust collection duct 110 can be selectively fixed to the lower surface of the storage section 130 so as to protrude to either the left or right. Therefore, the hose 301 of the dust collector 300 can be selectively connected to either the left or right side of the processing device 1000, and the dust collection duct 110 can be easily connected to the hose 301 of the dust collector 300 regardless of the positional relationship between the processing device 1000 and the dust collector 300. Also, since the cover part 112 is fixed to the lower surface of the storage part 130 and the duct part 114 is arranged to pass between the two legs 103, the direction of the dust collection duct 110 can be easily switched.

[0083] In particular, in the case of this embodiment, since the connection ports 111 are provided on both the front and rear sides, the hose 301 of the dust collector 300 can be selectively connected to four positions in the front, rear, left and right directions. This increases the degree of freedom in the installation location of the dust collector 300 and the connection location of the hose 301, making it easier to connect the dust collection duct 110 and the hose 301 of the dust collector 300 regardless of the positional relationship between the processing device 1000 and the dust collector 300.

[0084] Furthermore, when a hose 301 is connected to the front connection port 111, the operator of the processing device 1000 can remove this hose 301 from the connection port 111, open the front opening door 102, and place the hose 301 into the processing space 140, making it easier to use this hose 301 to clean the inside of the processing space 140.

[0085] [Another example of a dust collection duct] In the above embodiment, the dust collection duct 110 having a plurality of connection ports 111 has been described, but the connection port 111 may be rotatable as shown in Figs. 13(a) and 13(b). For example, the dust collection duct 110A shown in Figs. 13(a) and 13(b) may have a single connection port 111, and may be rotated to change the direction in which the connection port 111 is open. That is, the dust collection duct 110A shown in Figs. 13(a) and 13(b) has a processing machine side duct portion 116 fixed to the storage portion 130 of the processing machine 100, and a connection side duct portion 117 having the connection port 111 and rotatably connected to the processing machine side duct portion 116 so that the direction of the connection port 111 can be changed. The processing machine side duct portion 116 is a portion corresponding to the above-mentioned cover portion 112 and duct portion 114, and is configured by shortening the duct portion 114 and eliminating the connection port 111. Further, at the tip of the processing machine side duct portion 116, a cylindrical portion 116a is provided to which the connection side duct portion 117 is rotatably connected.

[0086] The connection side duct portion 117 has a first cylindrical portion 117a detachably fixed to the cylindrical portion 116a, and a second cylindrical portion 117b formed so as to be bent at a substantially right angle from the first cylindrical portion 117a and having a connection port 111. For example, when the first cylindrical portion 117a is fixed to the cylindrical portion 116a with the connection port 111 facing either forward or backward, the connection side duct portion 117 can select the direction of the connection port 111 in two directions, forward or backward. In addition, the direction of the connection port 111 can be changed to an upward direction regardless of forward or backward, and the degree of freedom of connection of the hose 301 can be increased. The other configurations are the same as those of the above-mentioned dust collection duct 110, such as the fact that the dust collection duct 110A can be selectively fixed to the lower surface of the storage portion 130 so as to protrude in either the left or right direction from the exterior cover 101.

[0087] <Other embodiments> In the above embodiment, the housing for housing the processing machine 100 is the exterior cover 101, but the exterior cover may also function as a housing portion that forms the processing space. [Explanation of symbols]
