Therefore, when the tool 22 is stored in the storage units 28-1a, 28-1b, 40-1a, and 40-1b in the magazine unit 60 in which the magazine additional member 40 is connected to the magazine 28, the storage unit 28-1a. Since the ring-shaped magnet 36 is disposed in the opening 28-1aa, the disk 22-1 is attracted to the magnet 36 in the magazine 60 in which the magazine additional member 40 is connected to the magazine 28. The tool 22 is stored in the storage portion 28-1a. In addition, since the ring-shaped magnet 38 is disposed in the opening 28-1ba of the storage portion 28-1b, the disk 22-1 is a magnet in the magazine portion 60 in which the magazine additional member 40 is connected to the magazine 28. The tool 22 is accommodated in the accommodating portion 28-1b while being adsorbed by 38. Further, since the ring-shaped magnet 46 is disposed in the opening 40-1aa of the storage unit 40-1a, in the magazine unit 60 in which the magazine additional member 40 is connected to the magazine 28, the disk 22-1 is a magnet. The tool 22 is accommodated in the accommodating portion 40-1a while being adsorbed by 46. Furthermore, since the ring-shaped magnet 48 is disposed in the opening 40-1ba of the storage unit 40-1b, the disk 22-1 is formed in the magazine unit 60 in which the magazine additional member 40 is connected to the magazine 28. The tool 22 is stored in the storage unit 40-1b while being attracted to the magnet 48.

  As described above, in the processing apparatus 10, when processing the workpiece 200 with one or two tools 22 (that is, when processing is performed without connecting the magazine additional member 40 to the magazine 28 in the magazine portion 60). And the case where the workpiece 200 is processed with three or four tools 22 (that is, when the magazine additional member 40 is connected to the magazine 28 in the magazine section 60 for processing). The user can select according to the quality of the processed product to be manufactured.

  Therefore, when the workpiece 200 is processed with the three or four tools 22 from the state where the workpiece 200 is processed with the one or two tools 22 in the processing apparatus 10, or When the workpiece 200 is processed with the two tools 22 from the state where the workpiece 200 is processed with the four tools 22, correction jigs 50 and 52 (described later) are used, respectively. The microcomputer 32 determines whether to process the workpiece 200 with one or two tools 22 or whether to process the workpiece 200 with three or four tools 22.

  When processing the workpiece 200 with one or two tools 22, the operator can use only the magazine 28 to fix the holding member 28-2 to the upper surface 28-1e of the base member 28-1. The correction jig 50 is held by the holding part 16 while the part 60 is formed.

  The correction jig 50 is formed of a metal material, and is inserted into the hole 26-1 of the rotating member 26 on the back surface 50bb which is the surface on the right side of the disk member 50b formed in parallel to the YZ plane. Is formed, and a plate-like member 50c that is parallel to the XY plane and extends in the X-axis direction is formed on a surface 50ba that is the left side surface of the disc member 50b (FIG. 6). (See (a)).

  Then, the support jig 50a is inserted into the hole 26-1 and fixed, whereby the correction jig 50 is fixed to the rotating member 26.

  The support shaft 50a is formed to extend in the X-axis direction, and the center axis of the support shaft 50a, the center of the disc member 50b, and the center axis of the plate-like member 50c are located on the same axis, and the support shaft 50a. , The center of the disc member 50b, and the axis O2 where the center axis of the plate-like member 50c is positioned so as to coincide with the center axis O of the rotating member 26 when the correction jig 50 is fixed to the rotating member 26. Has been made.

  That is, the correction jig 50 fixed to the rotating member 26 can rotate around the X axis about the central axis O of the rotating member 26.

  The disc member 50b is designed so that the radius r1 is, for example, 14 mm <r1 ≦ 16 mm.

  When processing the workpiece 200 with three or four tools 22, the operator connects the magazine expansion member 40 to the magazine 28 with the magazine expansion member 40 fixed to the base member 28-1. Thus, the magazine portion 60 is formed, and the correction jig 52 is held by the holding portion 16 via the adapter 34. That is, in this case, the correction jig 52 to be held by the holding member 16 can be regarded as the correction jig 52 fixed to the adapter 34.

  The correction jig 52 is formed of a metal material, a plate-like member 52c is formed in parallel to the XY plane, and a support shaft 52a is formed on an end surface 52ca on the left side of the plate-like member 52c. (See FIG. 6 (b)).

  The support shaft 52a is inserted into the hole 34-1aa and fixed to the adapter 34, and the support shaft 34-2 of the adapter 34 is inserted into the hole 26-1 of the rotating member 26 and fixed, whereby the holding member 52 is fixed. Is fixed to the rotating member 26 via the adapter 34.

  The support shaft 52a is formed so as to extend in the X-axis direction, and the center axis of the support shaft 52a and the center axis of the plate-like member 52c are located on the same axis, and the center axis of the support shaft 52a and the plate-like member 52c. The axis O3 where the central axis of the rotating member 26 is aligned with the central axis O of the rotating member 26 when the correction jig 50 is fixed to the rotating member 26 via the adapter 34.

That is, the correction jig 52 fixed to the rotating member 26 via the adapter 34 can rotate around the X axis about the central axis O of the rotating member 26.

Moreover, the illumination part 17 irradiates the process space 30 with the light of the brightness which can be visually recognized through the transparent cover 12a in the process space 30, Comprising: For example, white, blue The processing space 30 can be irradiated with green light.

  In the above configuration, a case where the workpiece 200 is processed into a desired shape by the processing apparatus 10 will be described.

  First, the operator connects the magazine expansion member 40 to the magazine 28 according to the quality of the processed product to be produced.

  When manufacturing a processed product using one or two tools 22, the magazine extension member 40 is not connected to the magazine 28 in the magazine section 60, and the two tools 22 can be set in the magazine 28. The correction pin 50 is stored in the storage unit 28-1 a, and the correction jig 50 is fixed to the rotating member 26 of the holding unit 16, thereby holding the correction jig 50 in the holding unit 16. The correction pin becomes conductive when it comes into contact with a member made of metal, and the microcomputer 32 detects the continuity, thereby obtaining a coordinate value or the like that is confirmed to be conductive.

When manufacturing a processed product using three or four tools 22, the magazine additional member 40 is connected to the magazine 28 in the magazine unit 60, and the four tools 22 can be set in the magazine 28. The correction pin 52 is stored in the storage unit 28-1a, and the correction jig 52 is fixed to the rotating member 26 of the holding unit 16 via the adapter 34, whereby the holding unit 16 holds the correction jig 52.

  Thereafter, the operator activates the processing apparatus 10 and the operator operates an operator (not shown) provided in the processing apparatus 10 to instruct start of determination of the number of tools that can be stored. Then, in the microcomputer 32, a determination process for detecting whether the magazine extension member 40 is connected to the magazine 28 in the magazine unit 60 is started.

That is, in this determination process, whether or not the magazine expansion member 40 is attached to the magazine 28 is detected in the magazine section 60, and can be stored in the magazine section 60 in the microcomputer 32 based on the detection result. It is determined that the number of tools 22 is two or four.

  Here, the flowchart of FIG. 7 shows the detailed processing contents of the determination processing. In this determination processing, first, a moving member (not shown) is moved in the cutting unit 14 to the spindle 20. The correction pin is gripped (step S702).

  Thereafter, the spindle 20 is moved by a moving member (not shown), and the distance A from the central axis O to the upper end portion at the connecting portion between the rotating member 26 and the member attached to the rotating member 26 by the attached correction pin. Is acquired (step S704).

  The member attached to the rotating member 26 is specifically the correction jig 50 when the magazine additional member 40 is not connected to the magazine 28, and the magazine additional member 40 is connected to the magazine 28. If it is, the adapter 34 is used.

  The connecting portion between the member attached to the rotating member 26 and the rotating member 26 is a portion located in the vicinity of the distal end surface 26a of the rotating member 26 in the member, and is, for example, left by 2.3 mm from the distal end surface 26a. It is a part located on the side. Specifically, the correction jig 50 is a portion where the disk member 50b is located, and the adapter 34 is near the rear end surface 34-1b of the rear portion 34-1d.

  Further, for the distance A, the Z coordinate value of the upper end portion at the connecting portion between the rotating member 26 and the member attached to the rotating member 26 is acquired, and the acquired Z coordinate value and the Z axis of the central axis O stored in advance are acquired. It is calculated based on the coordinate value.

Therefore, in the process of step S704, when the correction jig 50 is attached to the rotating member 26, the distance A from the central axis O to the upper end portion Pt1 of the disk member 50b of the correction jig 50 is ( 8 (a), the distance A at this time coincides with the radius r1 of the disc member 50b, and 14 mm <distance A ≦ 16 mm. When the adapter 34 is attached to the rotating member 26, the distance A from the central axis O to the upper end portion Pt2 in the rear portion 34-1d of the adapter 34 is obtained (see FIG. 8B). The value of the distance A at this time is a value that matches the radius r2 of the circular shape that is the cross section of the rear portion 34-1d, and 12 mm <distance A ≦ 14 mm.

  When the distance A is acquired in the process of step S702, it is determined whether or not the acquired value of the distance A is included in a range greater than 14 mm and less than or equal to 16 mm (step S706).

  If it is determined in step S706 that the distance A is within the range of greater than 14 mm and less than or equal to 16 mm, the determination result is stored, and the process proceeds to step S710 described later.

  If it is determined in step S706 that the distance A is greater than 14 mm and not included in the range of 16 mm or less, the value of the distance A is greater than 12 mm and included in the range of 14 mm or less. Is determined (step S708).

  In the determination process of step S708, if it is determined that the distance A is greater than 12 mm and not included in the range of 14 mm or less, the correction jig 50 or the correction jig 52 is not connected to the rotating member 26. This determination process is terminated. When ending the determination process, a display unit (not shown) provided in the processing apparatus 10 or a display unit (not shown) of a personal computer (not shown) provided separately. For example, the operator may be informed that an appropriate correction jig is not attached in the determination process.

  On the other hand, in the determination process of step S708, if it is determined that the distance A is within the range of greater than 12 mm and less than 14 mm, the spindle 20 is moved by a moving member (not shown) after storing the determination result. It moves and acquires the X coordinate value of the left end surface of the magazine part 60 (step S710).

  The left end surface of the magazine portion 60 is the left end surface S1 of the holding member 28-2 when the magazine additional member 40 is not attached to the magazine 28, and the magazine 28 has a magazine. When the additional member 40 is attached, it becomes the left side end surface S2 of the holding member 40-2.

  Therefore, in the process of step S710, when the magazine extension member 40 is not attached to the magazine 28 in the magazine section 60, the X coordinate value of the left side end surface S1 of the holding member 28-2 is B1. When the magazine extension member 40 is attached to the magazine 28 in the magazine section 60, the X coordinate value of the left side end surface S2 of the holding member 40-2 is B2. Note that “B1” is the X coordinate value of the left end surface of the magazine portion 60 when the magazine additional member 40 is not connected to the magazine 28 stored in advance, and “B2” This is the X coordinate value of the left end face of the magazine section 60 when the magazine expansion member 40 is connected to the magazine 28 stored in advance.

  Then, when the X coordinate value of the left end face of the magazine unit 60 is acquired in the process of step S710, whether or not the distance A is greater than 14 mm and less than or equal to 16 mm and the X coordinate value is B1. Is determined (step S712).

  That is, in the determination process in step S712, the determination is made based on the determination result obtained in the determination process in step S706, the X coordinate value acquired in the process in step S710, and the previously stored X coordinate value B1. is there. At this time, even if the X coordinate value acquired in the process of step S710 does not completely match the previously stored X coordinate value B1 and is included in a predetermined range centering on B1, the process of step S710 is also performed. You may make it judge that the X coordinate value acquired by the process corresponds with the X coordinate value B1 memorize | stored previously.

  In the determination process of step S712, when it is determined that the distance A is greater than 14 mm and within a range of 16 mm or less and the X coordinate value is B1, the magazine unit 60 adds the magazine additional member to the magazine 28. It is detected that 40 is not attached, and in the microcomputer 32, it is determined that the two tools 22 can be stored in the magazine section 60 (step S716), and this determination processing ends.

  In the processing of step S716, the microcomputer 32 determines that the two tools 22 can be stored in the magazine unit 60, and the color of light emitted from the illumination unit 17 is, for example, blue. To do.

  On the other hand, if it is determined in step S712 that the distance A is greater than 14 mm and within a range of 16 mm or less and the X coordinate value is not B1, then the distance A is greater than 12 mm. , 14 mm or less, and whether the X coordinate value is B2 is determined (step S714).

  That is, in the determination process of step S714, the determination is made based on the determination result of the determination process of step S708, the X coordinate value acquired in the process of step S710, and the previously stored X coordinate value B2. is there. At this time, even if the X coordinate value acquired in the process of step S710 does not completely match the X coordinate value B2 stored in advance and falls within a predetermined range centering on B2, the process of step S710 is also performed. You may make it judge that the X coordinate value acquired by the process corresponds with the X coordinate value B2 memorize | stored previously.

  In the determination process of step S714, when it is determined that the distance A is greater than 12 mm and within a range of 14 mm or less and the X coordinate value is B2, the magazine unit 60 adds the magazine additional member to the magazine 28. It is detected that 40 is attached, and in the microcomputer 32, it is determined that the four tools 22 can be stored in the magazine section 60 (step S718), and this determination processing is ended.

  In the process of step S718, the microcomputer 32 determines that the four tools 22 can be stored in the magazine unit 60, and the color of light emitted from the illumination unit 17 is, for example, green. To do.

On the other hand, in the determination process of step S714, if it is determined that the distance A is greater than 12 mm and not greater than 14 mm and the X coordinate value is not B2, it is determined that the magazine unit 60 is not appropriate. Then, this determination process ends. When ending the determination process, a display unit (not shown) provided in the processing apparatus 10 or a display unit (not shown) of a personal computer (not shown) provided separately. For example, the operator may be informed that the magazine unit 60 is not appropriate in the determination process.

  When the determination process is completed in this way, position correction, tilt correction, and the like are performed, and the user origin and correction values are acquired.

  In addition, about the technique which acquires a user origin, a correction value, etc., since a conventionally well-known technique can be used, the detailed description is abbreviate | omitted.

  Further, as the user origin, when the magazine additional member 40 is not connected to the magazine 28, for example, the user origin is the center position of the front end surface 26a of the rotating member 26, and the magazine additional member 40 is connected to the magazine 28. For example, the center position of the tip surface 34-1a of the adapter 34 is set.

  Thereafter, the operator visually confirms the magazine portion 60 in the processing space 30 and the color of the illumination, and if there is no mistake in the confirmed color, the operator opens the cover 12a of the housing 12 and processes the holding portion 16 to be processed. The object 200 is held, and the tool 22 used in the processing is stored in the magazine unit 60. The operator can know in advance the color difference between when the magazine extension member 40 is attached to the magazine 28 and when it is not attached to the magazine 28 by referring to a manual or the like. If there is an error in the color, it is determined that a malfunction has occurred in the processing apparatus 10.

  Specifically, when the magazine additional member 40 is not connected to the magazine 28 in the magazine portion 60, the workpiece 200 is fixed to the rotating member 26, and one or two tools 22 are stored in the magazine portion 60. . Further, when the magazine expansion member 40 is connected to the magazine 28 in the magazine section 60, the workpiece 200 is fixed to the rotating member 26 via the adapter 34, and the magazine section 60 to which the magazine expansion member 40 is connected. 3 or 4 tools 22 are housed in the container.

  After the workpiece 200 is held by the holding unit 16 in this manner, the cover 12a of the housing 12 is closed, and information such as processing data is micro-received from a personal computer (not shown) provided separately from the processing apparatus 10. Input to the computer 32.

Then, the dust collector (not shown) connected via the dust collection pipe (not shown) is started, and the operator starts the cutting process via the operation panel (not shown). Is controlled, the cutting of the workpiece 200 is performed based on the input machining data, the number of tools 22 that can be accommodated in the magazine section 60, the correction value, and the like.

  As described above, the processing apparatus 10 according to the present invention includes a magazine 28 including two storage units that can store the tool 22, and can be connected to the magazine 28, and includes two storage units. The magazine portion 60 is configured by the magazine extension member 40.

  The magazine 28 includes a base member 28-1 having two storage portions 28-1a and 28-1b, a hole 28-2a for holding the tool 22 stored in the storage portion 28-1a, and a storage portion 28-. And a holding member 28-2 having a hole 28-2b for holding the tool 22 accommodated in 1b.

  The magazine expansion member 40 includes a base member 40-1 having two storage portions 40-1a and 40-1b, a hole 40-2a for holding the tool 22 stored in the storage portion 28-1a, A hole 40-2b for holding the tool 22 stored in the storage unit 28-1b, a hole 40-2g for holding the tool 22 stored in the storage unit 40-1a, and a tool 22 stored in the storage unit 40-1b. And holding member 40-2 having a hole 40-2h for holding.

  When the magazine extension member 40 is not connected to the magazine 28 in the magazine portion 60, the correction jig 50 or the workpiece 200 is fixed to the rotating member 26 of the holding portion 16. Further, when the magazine extension member 40 is connected to the magazine 28 in the magazine portion 60, the correction jig 50 and the workpiece 200 are fixed to the rotating member 26 of the holding portion 16 via the adapter 34.

Thereby, in the processing apparatus 10 according to the present invention, the number of tools 22 stored in the magazine section 60 can be increased or decreased according to the quality of the processed product to be manufactured.

  In addition, the processing apparatus 10 according to the present invention is configured so that the center of the rotating member 26 starts from the upper end portion of the portion of the member attached to the rotating member 26 located near the front end surface 26a before the workpiece 200 is processed. While measuring the distance to the axis | shaft O, the X coordinate value of the end surface of the left side of the magazine part 60 was measured.

  Based on the measurement result, the magazine unit 60 detects whether or not the magazine expansion member 40 is connected to the magazine 28, and the magazine unit 60 detects that the magazine expansion member 40 is not connected to the magazine 28. Then, the microcomputer 32 determines that the number of tools 22 that can be stored in the magazine section 60 is two, and if the magazine section 60 detects that the magazine expansion member 40 is connected to the magazine 28, the microcomputer 32. In FIG. 4, it is determined that the number of tools 22 that can be stored in the magazine section 60 is four.

As a result, in the processing apparatus 10 according to the present invention, it is possible to automatically determine whether or not the magazine expansion member 40 is connected to the magazine 28 in the magazine section 60.

  Moreover, the processing apparatus 10 by this invention changed the color of the illumination which illuminates the inside of the processing space 30 based on the determination result.

Thereby, in the processing apparatus 10 according to the present invention, the operator can visually confirm the determination of the number of tools that can be stored in the processing apparatus 10 and the actual magazine portion 60.

  The embodiment described above may be modified as shown in the following (1) to (8).

  (1) In the above-described embodiment, the magazine 28 has a holding member provided with two holes for holding the tool 22 stored in the storage unit in the base member 28-1 including the two storage units. Although it is configured to have 28-2, it is needless to say that the present invention is not limited to this.

  That is, the base member may be provided with one storage portion, and the holding member may be provided with one hole for holding the tool 22 in the storage portion.

  Alternatively, the base member includes three or more storage units along the X-axis direction, and the holding member has the number of storage units formed on the base member that holds the tool 22 stored in each storage unit. The same number of holes may be provided.

  At this time, the circular hole formed in the holding member 40-2 in the magazine additional member 40 increases or decreases according to the number of storage portions in the base member.

  (2) In the above-described embodiment, the magazine extension member 40 connected to the magazine 28 is held by the base member 40-1 having two storage portions, and the tool 22 stored in the storage portion is held.

However, the present invention is not limited to this.

  In other words, the base member of the magazine extension member 40 may be provided with one storage portion, and the holding member of the magazine extension member 40 may be provided with one hole for holding the tool in the storage portion.

  Alternatively, the base member of the magazine expansion member 40 includes three or more storage units along the X-axis direction, and the base member that holds the tool 22 stored in each storage member in the holding member of the magazine expansion member 40. You may make it provide the same number of holes as the number of the accommodating parts formed in the base member.

  (3) In the above-described embodiment, in the process of step S716, it is determined that two tools are stored, and the illumination unit 17 emits blue light, and in the process of step S718, 4 While it is determined that the book tool is housed and green light is emitted from the illuminating unit 17, it is needless to say that the present invention is not limited to this.

  That is, in the process of step S716, the illumination unit 17 may emit red light, and in the process of step S718, the illumination unit 17 may emit blue light. If the color of the light emitted from the illumination unit 17 in the processing of step S718 is different from the color of the light emitted from the illumination unit 17 in the processing of step S718, the light emitted from the irradiation unit 17 in each processing is as described above. A color different from the color may be used.

  (4) In the above embodiment, the radius r1 of the disc member 50b is 14 mm <r1 ≦ 16 mm, and the radius r2 of the cross section of the rear portion 34-1d of the adapter 34 is 12 mm <r2 ≦ 14 mm.

  (5) In the above-described embodiment, when the magazine extension member 40 is connected to the magazine 28 in the magazine section 60, the correction jig 52 is fixed to the rotating member 26 via the adapter 34. It goes without saying that the correction jig 52 fixed to the rotating member 26 when the magazine additional member 40 is connected to the magazine 28 may have a shape in which the correction jig 52 is fixed to the adapter 34.

  In this case, when the correction jig is fixed to the rotating member 26, it is directly fixed to the rotating member 26 without using the adapter 34.

  (6) Although not particularly described in the above-described embodiment, for example, as the processing apparatus 10, dental ceramic is used as the workpiece 200, and the dental ceramic is cut into a desired shape to artificial teeth. It is good also as an artificial tooth production apparatus which produces.
