用以實施發明之形態The form used to implement the invention

以下，針對本發明實施形態之自動更換裝置，一面參照圖式一面說明。The following describes the automatic replacement device according to an embodiment of the present invention with reference to the drawings.

(自動更換裝置2) 參照圖1來說明，整體以符號2表示之自動更換裝置具備保管複數個切削刀片之切削刀片保管機構4、與從切削刀片保管機構4搬出以及搬入切削刀片之搬出入機構6。 (Automatic replacement device 2) Referring to FIG. 1 , the automatic replacement device generally indicated by symbol 2 includes a cutting blade storage mechanism 4 for storing a plurality of cutting blades, and a loading and unloading mechanism 6 for loading and unloading cutting blades from the cutting blade storage mechanism 4.

X軸方向是圖1中以箭頭X表示之方向，Y軸方向是圖1中以箭頭Y表示之方向且是正交於X軸方向之方向。又，Z軸方向是圖1以箭頭Z表示之方向且為正交於X軸方向以及Y軸方向之上下方向。X軸方向以及Y軸方向所規定之平面實質上是水平的。The X-axis direction is the direction indicated by the arrow X in FIG1 , and the Y-axis direction is the direction indicated by the arrow Y in FIG1 and is a direction perpendicular to the X-axis direction. In addition, the Z-axis direction is the direction indicated by the arrow Z in FIG1 and is an up-down direction perpendicular to the X-axis direction and the Y-axis direction. The plane defined by the X-axis direction and the Y-axis direction is substantially horizontal.

(切削刀片保管機構4) 如圖2所示，切削刀片保管機構4包含：驅動齒輪16，具有在Y軸方向上延伸之旋轉軸14；從動齒輪20，和驅動齒輪16在Z軸方向上分開且具有在Y軸方向上延伸之旋轉軸18；無端軌道22，捲繞於驅動齒輪16與從動齒輪20；及刀片支撐軸24，在Y軸方向上延伸並以預定的間隔配設在無端軌道22，且可***切削刀片的中央開口部來支撐切削刀片。 (Cutting blade storage mechanism 4) As shown in FIG. 2, the cutting blade storage mechanism 4 includes: a driving gear 16 having a rotating shaft 14 extending in the Y-axis direction; a driven gear 20 separated from the driving gear 16 in the Z-axis direction and having a rotating shaft 18 extending in the Y-axis direction; an endless track 22 wound around the driving gear 16 and the driven gear 20; and a blade support shaft 24 extending in the Y-axis direction and arranged at a predetermined interval on the endless track 22, and capable of being inserted into the central opening of the cutting blade to support the cutting blade.

(驅動齒輪16) 參照圖1以及圖2來說明，本實施形態之切削刀片保管機構4包含基座板26(參照圖1)、從基座板26的上表面朝上方延伸之支撐壁28、與固定在支撐壁28的單面之馬達30。如圖2所示，在馬達30連結有驅動齒輪16的旋轉軸14，且馬達30形成為以Y軸方向為軸心來使驅動齒輪16旋轉。 (Driving gear 16) Referring to FIG. 1 and FIG. 2, the cutting blade storage mechanism 4 of this embodiment includes a base plate 26 (see FIG. 1), a support wall 28 extending upward from the upper surface of the base plate 26, and a single-sided motor 30 fixed to the support wall 28. As shown in FIG. 2, the motor 30 is connected to the rotating shaft 14 of the driving gear 16, and the motor 30 is formed to rotate the driving gear 16 with the Y-axis direction as the axis.

(從動齒輪20) 如圖2所示，從動齒輪20配置於驅動齒輪16的上方，且從動齒輪20的旋轉軸18是以Y軸方向為軸心而旋轉自如且在Z軸方向上升降自如地支撐於支撐壁28。於支撐壁28設置有使從動齒輪20在Z軸方向上升降之升降機構(未圖示)。升降機構亦可為例如以下之構成：具有連結於從動齒輪20的旋轉軸18且在Z軸方向上延伸之滾珠螺桿、及使此滾珠螺桿旋轉之馬達。 (Driven gear 20) As shown in FIG. 2, the driven gear 20 is arranged above the driving gear 16, and the rotating shaft 18 of the driven gear 20 is supported on the supporting wall 28 so as to be freely rotatable about the Y-axis direction and freely rise and fall in the Z-axis direction. A lifting mechanism (not shown) for lifting and falling the driven gear 20 in the Z-axis direction is provided on the supporting wall 28. The lifting mechanism may also be, for example, the following structure: a ball screw connected to the rotating shaft 18 of the driven gear 20 and extending in the Z-axis direction, and a motor for rotating the ball screw.

(無端軌道22) 無端軌道22是由相互連結之多數個連結片(省略符號)所構成，且捲繞於驅動齒輪16與從動齒輪20。無端軌道22形成為因應於藉由馬達30使驅動齒輪16旋轉而旋轉。 (Endless track 22) The endless track 22 is composed of a plurality of connecting pieces (abbreviated symbols) connected to each other, and is wound around the driving gear 16 and the driven gear 20. The endless track 22 is formed to rotate in response to the driving gear 16 rotating by the motor 30.

在本實施形態之切削刀片保管機構4中是形成為可以藉由以升降機構改變從動齒輪20的Z軸方向的位置，來調整驅動齒輪16與從動齒輪20的Z軸方向之間隔。又，在切削刀片保管機構4中是形成為可以藉由合宜增減無端軌道22的連結片之數量，來調整無端軌道22的長度。In the cutting blade storage mechanism 4 of the present embodiment, the distance between the driving gear 16 and the driven gear 20 in the Z-axis direction can be adjusted by changing the position of the driven gear 20 in the Z-axis direction by the lifting mechanism. In addition, in the cutting blade storage mechanism 4, the length of the endless track 22 can be adjusted by appropriately increasing or decreasing the number of connecting pieces of the endless track 22.

(刀片支撐軸24) 如圖2所示，刀片支撐軸24是隔著預定的間隔而在無端軌道22配設有複數個。又，如藉由將圖3和圖2一起參照所可理解地，刀片支撐軸24具有連結於無端軌道22之圓柱狀的基部32、與從基部32的端面朝Y軸方向延伸之圓柱狀的軸部34。軸部34的直徑比基部32的直徑更小。 (Blade support shaft 24) As shown in FIG. 2, a plurality of blade support shafts 24 are provided on the endless track 22 at predetermined intervals. As can be understood by referring to FIG. 3 together with FIG. 2, the blade support shaft 24 has a cylindrical base 32 connected to the endless track 22, and a cylindrical shaft 34 extending from the end surface of the base 32 toward the Y-axis direction. The diameter of the shaft 34 is smaller than the diameter of the base 32.

(切削刀片) 在圖3中，也顯示有作為被切削刀片保管機構4所保管之切削刀片的輪轂型刀片36。輪轂型刀片36具有環狀的基台38、與配設在基台38的外周之環狀的切刃40。基台38可由鋁合金等合宜的金屬材料來形成。於基台38的其中一個側面施加有表示輪轂型刀片36的種類之標示T(在圖示之例中為「A005」)。標示T可由文字、數字、條碼等構成。又，於基台38的中央部設置有圓形的中央開口部38a。切刃40是由鑽石等之磨粒、與金屬或樹脂等之結合材來形成為預定的厚度(例如10~30μm左右)，且從基台38的外周緣朝徑方向外側突出。 (Cutting blade) FIG. 3 also shows a hub-type blade 36 as a cutting blade stored in a cutting blade storage mechanism 4. The hub-type blade 36 has an annular base 38 and an annular cutting edge 40 arranged on the outer periphery of the base 38. The base 38 can be formed of a suitable metal material such as an aluminum alloy. A mark T indicating the type of the hub-type blade 36 is applied to one of the side surfaces of the base 38 (in the example shown, "A005"). The mark T can be composed of letters, numbers, bar codes, etc. In addition, a circular central opening 38a is provided in the central portion of the base 38. The cutting blade 40 is formed of abrasive grains such as diamond and a bonding material such as metal or resin to a predetermined thickness (e.g., about 10 to 30 μm), and protrudes radially outward from the outer periphery of the base 38.

本實施形態之刀片支撐軸24的軸部34具備有和輪轂型刀片36的中央開口部38a的內徑對應之外徑，且在刀片支撐軸24中形成為軸部34可***輪轂型刀片36的中央開口部38a，而以軸部34支撐複數個(例如5個)輪轂型刀片36。再者，雖然在相同的刀片支撐軸24是***相同種類的切削刀片，但作為切削刀片保管機構4整體，可保管材料或形狀不同之複數個種類的切削刀片。The shaft portion 34 of the blade support shaft 24 of the present embodiment has an outer diameter corresponding to the inner diameter of the central opening portion 38a of the hub-type blade 36, and the shaft portion 34 is formed in the blade support shaft 24 so that the central opening portion 38a of the hub-type blade 36 can be inserted, and a plurality of (e.g., five) hub-type blades 36 are supported by the shaft portion 34. Furthermore, although the same type of cutting blades are inserted into the same blade support shaft 24, the cutting blade storage mechanism 4 as a whole can store a plurality of types of cutting blades of different materials or shapes.

在本實施形態中，如藉由參照圖2所可理解地，是在複數個刀片支撐軸24當中一半數量的刀片支撐軸24上支撐有輪轂型刀片36。又，如圖3所示，在軸部34的前端側，在圓周方向上隔著間隔而裝設有複數個定位珠(ball plunger)42，前述定位珠42用於防止以軸部34所支撐之輪轂型刀片36的飛出。In this embodiment, as can be understood by referring to FIG2 , a hub-type blade 36 is supported on half of the blade supporting shafts 24 among the plurality of blade supporting shafts 24. Also, as shown in FIG3 , a plurality of positioning balls (ball plungers) 42 are installed at intervals in the circumferential direction on the front end side of the shaft portion 34, and the positioning balls 42 are used to prevent the hub-type blade 36 supported by the shaft portion 34 from flying out.

如圖4所示，於刀片支撐軸24的各基部32的內部形成有流路32a，且在無端軌道22形成有連通於各流路32a的一端部之複數條流路22a。如圖3所示，各流路32a的另一端部在比軸部34更靠近徑方向外側之基部32的端面形成有開口。As shown in FIG4 , a flow path 32a is formed inside each base portion 32 of the blade support shaft 24, and a plurality of flow paths 22a connected to one end of each flow path 32a are formed in the endless track 22. As shown in FIG3 , the other end of each flow path 32a is formed with an opening at the end surface of the base portion 32 closer to the outside of the shaft portion 34 in the radial direction.

又，如圖2所示，在支撐壁28設有在驅動齒輪16的下方朝Y軸方向突出之空氣噴嘴44，且空氣噴嘴44已連接於高壓空氣供給機構(未圖示)。在本實施形態中，伴隨於無端軌道22旋轉之刀片支撐軸24之在軌道中位於最下端之刀片支撐軸24與空氣噴嘴44的前端相面對。As shown in FIG2 , an air nozzle 44 is provided on the support wall 28 below the drive gear 16 and protrudes in the Y-axis direction, and the air nozzle 44 is connected to a high-pressure air supply mechanism (not shown). In this embodiment, the blade support shaft 24 located at the bottom of the endless track 22 faces the front end of the air nozzle 44.

並且，在將位於軸部34的前端側之切削刀片搬出的情況下，形成為可以藉由從空氣噴嘴44透過無端軌道22之流路22a來對位於最下端之刀片支撐軸24的基部32的流路32a供給高壓空氣，而將留在軸部34的輪轂型刀片36朝軸部34的前端側推出。不過，因為定位珠42的作用而不會有輪轂型刀片36從軸部34掉落之情形。Furthermore, when the cutting blade located at the front end side of the shaft portion 34 is removed, the hub-type blade 36 remaining on the shaft portion 34 can be pushed out toward the front end side of the shaft portion 34 by supplying high-pressure air from the air nozzle 44 through the flow path 22a of the endless track 22 to the flow path 32a of the base portion 32 of the blade support shaft 24 located at the bottom. However, due to the effect of the positioning beads 42, the hub-type blade 36 will not fall off the shaft portion 34.

(墊圈型刀片45) 保管於切削刀片保管機構4之切削刀片並不限定於上述輪轂型刀片36，亦可為圖5所示之墊圈型刀片45。墊圈型刀片45是由形成為環狀之切刃所構成，且和輪轂型刀片36不同，不具有基台。於墊圈型刀片45的其中一個側面施加有表示墊圈型刀片45的種類之標示T(在圖示之例中為「B006」)。 (Backing ring type blade 45) The cutting blade stored in the cutting blade storage mechanism 4 is not limited to the above-mentioned hub type blade 36, and may be a backing ring type blade 45 shown in FIG. 5. The backing ring type blade 45 is composed of a cutting edge formed in an annular shape, and unlike the hub type blade 36, it does not have a base. A mark T indicating the type of the backing ring type blade 45 is applied to one side surface of the backing ring type blade 45 (in the example shown, "B006").

在墊圈型刀片45被切削刀片保管機構4保管的情況下，刀片支撐軸24的軸部34會形成為和墊圈型刀片45的中央開口部45a的內徑對應之外徑D。並且，可將軸部34***墊圈型刀片45的中央開口部45a，而藉由軸部34支撐複數片(例如10片)墊圈型刀片45。When the washer blade 45 is stored in the cutting blade storage mechanism 4, the shaft portion 34 of the blade support shaft 24 is formed to have an outer diameter D corresponding to the inner diameter of the central opening portion 45a of the washer blade 45. Furthermore, the shaft portion 34 can be inserted into the central opening portion 45a of the washer blade 45, and a plurality of (for example, 10) washer blades 45 can be supported by the shaft portion 34.

再者，在切削刀片保管機構4中，亦可形成為僅保管輪轂型刀片36或墊圈型刀片45的其中一者、或者亦可形成為可保管輪轂型刀片36以及墊圈型刀片45之雙方。又，在被切削刀片保管機構4保管中的切削刀片之種類，已按每個刀片支撐軸24預先登錄於自動更換裝置2的記憶體(未圖示)。Furthermore, the cutting blade storage mechanism 4 may be configured to store only one of the hub-type blade 36 and the washer-type blade 45, or may be configured to store both the hub-type blade 36 and the washer-type blade 45. Furthermore, the types of cutting blades stored in the cutting blade storage mechanism 4 are pre-registered in the memory (not shown) of the automatic replacement device 2 for each blade support shaft 24.

(搬出入機構6) 參照圖6來說明搬出入機構6。搬出入機構6至少具備在Z軸方向上延伸之Z旋轉軸46、呈放射狀地連結於Z旋轉軸46且吸引保持切削刀片之刀片保持部48、及對已形成於切削裝置的主軸的前端之公螺絲來螺接以及螺鬆固定螺帽之固定螺帽保持部50。 (Carry-in/out mechanism 6) The carry-in/out mechanism 6 is described with reference to FIG. 6. The carry-in/out mechanism 6 has at least a Z-rotation shaft 46 extending in the Z-axis direction, a blade holding portion 48 radially connected to the Z-rotation shaft 46 and attracting and holding the cutting blade, and a fixing nut holding portion 50 for screwing and loosening a fixing nut with a male screw formed on the front end of the main shaft of the cutting device.

如圖6所示，本實施形態的搬出入機構6更具備罩殼52，罩殼52具有正六角形狀之頂板54、與從頂板54的周緣垂下之矩形板狀的6個側壁56。從頂板54的上表面突出有上述Z旋轉軸46。在罩殼52的內部容置有連結於Z旋轉軸46之馬達(未圖示)。As shown in FIG6 , the loading and unloading mechanism 6 of this embodiment is further provided with a housing 52, and the housing 52 has a regular hexagonal top plate 54 and six rectangular plate-shaped side walls 56 hanging from the periphery of the top plate 54. The above-mentioned Z rotation axis 46 protrudes from the upper surface of the top plate 54. A motor (not shown) connected to the Z rotation axis 46 is accommodated inside the housing 52.

在本實施形態中，在罩殼52的6個側壁56當中，於4個側壁56裝設有刀片保持部48，於2個側壁56裝設有固定螺帽保持部50，且2個固定螺帽保持部50是設置在相向之一對側壁56。In this embodiment, among the six side walls 56 of the housing 52, the blade holding portions 48 are installed on four side walls 56, and the fixing nut holding portions 50 are installed on two side walls 56, and the two fixing nut holding portions 50 are provided on a pair of opposite side walls 56.

(刀片保持部48) 刀片保持部48形成為圓筒狀，且在刀片保持部48的端面58設有可承接上述刀片支撐軸24的軸部34以及切削裝置的主軸的前端部之圓形的中央開口部60、與在中央開口部60的周圍沿著圓周方向隔著等間隔而配置之複數個第一吸引孔61。 (Blade holding portion 48) The blade holding portion 48 is formed into a cylindrical shape, and a circular central opening portion 60 that can receive the shaft portion 34 of the blade support shaft 24 and the front end of the main shaft of the cutting device is provided on the end surface 58 of the blade holding portion 48, and a plurality of first suction holes 61 are arranged at equal intervals around the central opening portion 60 along the circumferential direction.

又，在端面58的外周部設置有環狀突出部62。在環狀突出部62形成有在圓周方向上隔著等間隔而配置之第二吸引孔63。第一/第二吸引孔61、63已連接到吸引機構(未圖示)。Furthermore, an annular protrusion 62 is provided on the outer periphery of the end surface 58. Second suction holes 63 are formed in the annular protrusion 62 and are arranged at equal intervals in the circumferential direction. The first and second suction holes 61, 63 are connected to a suction mechanism (not shown).

再者，環狀突出部62的內徑是形成為比支撐墊圈型刀片45之軸部34的外徑D稍微大，而讓環狀突出部62變得可承接支撐墊圈型刀片45之軸部34。Furthermore, the inner diameter of the annular protrusion 62 is formed to be slightly larger than the outer diameter D of the shaft portion 34 supporting the washer-type blade 45, so that the annular protrusion 62 can receive the shaft portion 34 supporting the washer-type blade 45.

刀片保持部48在已定位在使刀片保持部48的端面58接觸於被切削刀片保管機構4所保管之輪轂型刀片36的基台38的位置之狀態下，可藉由吸引機構在第一吸引孔61生成吸引力來吸引保持輪轂型刀片36。When the blade holding portion 48 is positioned so that the end surface 58 of the blade holding portion 48 contacts the base 38 of the hub-type blade 36 stored in the cutting blade storage mechanism 4, the suction mechanism can generate suction in the first suction hole 61 to attract and hold the hub-type blade 36.

又，刀片保持部48在保持墊圈型刀片45的情況下，是在已定位在刀片保持部48的環狀突出部62接觸於已保管在切削刀片保管機構4之墊圈型刀片45的側面之位置的狀態下，藉由吸引機構在第二吸引孔63生成吸引力，來吸引保持墊圈型刀片45。Furthermore, when the blade holding portion 48 holds the gasket-type blade 45, the annular protrusion 62 positioned in the blade holding portion 48 contacts the side surface of the gasket-type blade 45 stored in the cutting blade storage mechanism 4, and the suction mechanism generates suction in the second suction hole 63 to attract and hold the gasket-type blade 45.

(固定螺帽保持部50) 參照圖6來繼續說明，固定螺帽保持部50包含：圓筒狀的殼體64，固定於罩殼52的側壁56；環狀的旋轉體66，旋轉自如地容置在殼體64的內部；及馬達(未圖示)，使旋轉體66旋轉。 (Fixed nut holding part 50) Referring to FIG. 6, the fixed nut holding part 50 includes: a cylindrical housing 64 fixed to the side wall 56 of the housing 52; an annular rotating body 66 rotatably accommodated inside the housing 64; and a motor (not shown) to rotate the rotating body 66.

於旋轉體66形成有可承接切削裝置的主軸的前端部之中央開口部68。於旋轉體66的端面66a，在圓周方向上隔著間隔交互地設置有複數個吸引孔70與複數個銷72。A central opening 68 capable of receiving the front end of the main shaft of the cutting device is formed in the rotating body 66. A plurality of suction holes 70 and a plurality of pins 72 are alternately provided at intervals in the circumferential direction on the end surface 66a of the rotating body 66.

又，各吸引孔70已連接到吸引機構(未圖示)。銷72是藉由內置於旋轉體66之彈簧(未圖示)而定位在從旋轉體66的端面66a突出之位置(圖6所示之位置)，並且若朝向旋轉體66的內部被按壓時，會讓彈簧收縮而容置於旋轉體66的內部。又，銷72和已形成於固定螺帽之銷孔的位置對應而配置。In addition, each suction hole 70 is connected to a suction mechanism (not shown). The pin 72 is positioned at a position protruding from the end surface 66a of the rotating body 66 (the position shown in FIG. 6 ) by a spring (not shown) built into the rotating body 66, and when pressed toward the inside of the rotating body 66, the spring contracts and is accommodated inside the rotating body 66. In addition, the pin 72 is arranged to correspond to the position of the pin hole formed in the fixing nut.

在固定螺帽保持部50中，是形成為在以吸引機構在各吸引孔70生成吸引力來吸引保持固定螺帽，並且已將銷72***形成於固定螺帽之銷孔的狀態下，藉由馬達使旋轉體66旋轉，藉此可以對已形成於主軸的前端之公螺絲來螺接以及螺鬆用於將輪轂型刀片36或墊圈型刀片45固定於切削裝置的主軸之固定螺帽。In the fixed nut holding portion 50, a suction mechanism is used to generate suction in each suction hole 70 to attract and hold the fixed nut, and when the pin 72 has been inserted into the pin hole formed in the fixed nut, the motor is used to rotate the rotating body 66, thereby screwing and loosening the male screw formed on the front end of the main shaft to the fixed nut for fixing the hub-type blade 36 or the washer-type blade 45 to the main shaft of the cutting device.

再者，在要將固定螺帽從主軸螺鬆(取下)時，即使在固定螺帽保持部50的銷72的位置與固定螺帽的銷孔的位置已偏離的情況下，仍可將旋轉體66的端面66a定位在已裝設於主軸之固定螺帽的端面，並且若在將銷72容置於旋轉體66的內部之後，藉由馬達使旋轉體66旋轉，銷72會在銷72的位置對齊於銷孔的位置時被彈簧推出，而可對銷孔***銷72。Furthermore, when the fixing nut is to be loosened (removed) from the main shaft, even if the position of the pin 72 of the fixing nut retaining portion 50 is deviated from the position of the pin hole of the fixing nut, the end face 66a of the rotating body 66 can still be positioned at the end face of the fixing nut installed on the main shaft, and after the pin 72 is accommodated inside the rotating body 66, if the rotating body 66 is rotated by the motor, the pin 72 will be pushed out by the spring when the position of the pin 72 is aligned with the position of the pin hole, and the pin 72 can be inserted into the pin hole.

可如上述地構成之搬出入機構6，在本實施形態中是如圖1所示地配設在框體74的內部。框體74是在Y軸方向上移動自如地支撐於升降工作台76，且升降工作台76是在Z軸方向上升降自如地支撐於基座架台78。The loading and unloading mechanism 6 constructed as described above is arranged inside a frame 74 in the present embodiment as shown in Fig. 1. The frame 74 is supported on a lifting table 76 so as to be movable in the Y-axis direction, and the lifting table 76 is supported on a base frame 78 so as to be movable in the Z-axis direction.

(框體74) 若參照圖7以及圖8來說明，框體74包含矩形板狀的底部80、從底部80的上表面四個角落朝上方延伸之4個支柱82、與固定於各支柱82的上端之板狀的頂板部84(參照圖8)。在底部80的下表面，在X軸方向上隔著間隔而設置有一對被導引構件86，前述被導引構件86形成有在Y軸方向上延伸之溝86a。 (Frame 74) Referring to Fig. 7 and Fig. 8, frame 74 includes a rectangular plate-shaped bottom 80, four pillars 82 extending upward from the four corners of the upper surface of bottom 80, and a plate-shaped top plate 84 fixed to the upper ends of each pillar 82 (see Fig. 8). On the lower surface of bottom 80, a pair of guided members 86 are provided at intervals in the X-axis direction, and the guided members 86 are formed with grooves 86a extending in the Y-axis direction.

(升降工作台76) 如圖7所示，升降工作台76包含矩形板狀的頂板88、及從頂板88的下表面四個角落朝下方延伸之4個圓柱狀的腳部90。在頂板88的上表面設置有在X軸方向上隔著間隔且在Y軸方向上延伸之一對導軌92，且一對導軌92滑動自如地嵌合於框體74的一對被導引構件86的溝86a。 (Lifting table 76) As shown in FIG. 7, the lifting table 76 includes a rectangular plate-shaped top plate 88 and four cylindrical legs 90 extending downward from the four corners of the lower surface of the top plate 88. A pair of guide rails 92 extending in the Y-axis direction and spaced apart in the X-axis direction are provided on the upper surface of the top plate 88, and the pair of guide rails 92 are slidably engaged in the grooves 86a of the pair of guided members 86 of the frame 74.

(Y軸移動機構8) 又，在升降工作台76的頂板88的上表面設置有Y軸移動機構8。Y軸移動機構8具有在一對導軌92間在Y軸方向上延伸之滾珠螺桿94、與使滾珠螺桿94旋轉之馬達96。滾珠螺桿94的螺帽部(未圖示)已固定在框體74的底部80的下表面。 (Y-axis moving mechanism 8) In addition, a Y-axis moving mechanism 8 is provided on the upper surface of the top plate 88 of the lifting table 76. The Y-axis moving mechanism 8 has a ball screw 94 extending in the Y-axis direction between a pair of guide rails 92, and a motor 96 for rotating the ball screw 94. The nut portion (not shown) of the ball screw 94 is fixed to the lower surface of the bottom 80 of the frame 74.

在Y軸移動機構8中，是藉由滾珠螺桿94將馬達96的旋轉運動轉換成直線運動並傳達至框體74，而使框體74沿著一對導軌92在Y軸方向上移動。如此，配設有搬出入機構6之框體74形成為可滑動地支撐在已配設於升降工作台76之在Y軸方向上延伸之導軌92，且可藉由Y軸移動機構8來相對於切削刀片保管機構4定位到Y軸方向的作用位置與退避位置。In the Y-axis moving mechanism 8, the rotational motion of the motor 96 is converted into a linear motion by the ball screw 94 and transmitted to the frame 74, so that the frame 74 moves in the Y-axis direction along a pair of guide rails 92. In this way, the frame 74 equipped with the loading and unloading mechanism 6 is formed to be slidably supported on the guide rails 92 extending in the Y-axis direction and arranged on the lifting table 76, and can be positioned at the action position and the retreat position in the Y-axis direction relative to the cutting blade storage mechanism 4 by the Y-axis moving mechanism 8.

上述作用位置是搬出入機構6的刀片保持部48接近於切削刀片保管機構4之位置，且為可藉由刀片保持部48吸引保持已支撐於切削刀片保管機構4之切削刀片的位置。又，上述退避位置是搬出入機構6的刀片保持部48比上述作用位置更從切削刀片保管機構4拉開間隔之位置。The above-mentioned action position is a position where the blade holding portion 48 of the carrying-in/out mechanism 6 is close to the cutting blade storage mechanism 4, and is a position where the cutting blade supported by the cutting blade storage mechanism 4 can be attracted and held by the blade holding portion 48. In addition, the above-mentioned retreat position is a position where the blade holding portion 48 of the carrying-in/out mechanism 6 is further spaced from the cutting blade storage mechanism 4 than the above-mentioned action position.

(基座架台78) 如圖7所示，基座架台78包含框架98、與固定於框架98的上部之矩形狀的基座板100。在基座板100的四個角落形成有供升降工作台76的腳部90滑動自如地***之4個圓形孔102。又，基座板100的中央部形成有母螺絲104。 (Base frame 78) As shown in FIG. 7, the base frame 78 includes a frame 98 and a rectangular base plate 100 fixed to the upper portion of the frame 98. Four circular holes 102 are formed at the four corners of the base plate 100 for the legs 90 of the lifting platform 76 to be inserted slidably. In addition, a female screw 104 is formed in the center of the base plate 100.

(Z軸移動機構10) 參照圖7繼續說明，在升降工作台76以及基座架台78連結有Z軸移動機構10。Z軸移動機構10包含在Z軸方向上延伸之滾珠螺桿106、使滾珠螺桿106旋轉之馬達108、與固定於馬達108的上端之連結板110。滾珠螺桿106已螺合於基座板100的母螺絲104。連結板110可藉由螺栓(未圖示)等之合宜的連結機構而固定到升降工作台76的頂板88的下表面。 (Z-axis moving mechanism 10) Referring to FIG. 7, the Z-axis moving mechanism 10 is connected to the lifting table 76 and the base frame 78. The Z-axis moving mechanism 10 includes a ball screw 106 extending in the Z-axis direction, a motor 108 for rotating the ball screw 106, and a connecting plate 110 fixed to the upper end of the motor 108. The ball screw 106 is screwed to the female screw 104 of the base plate 100. The connecting plate 110 can be fixed to the lower surface of the top plate 88 of the lifting table 76 by a suitable connecting mechanism such as a bolt (not shown).

在Z軸移動機構10中，是藉由滾珠螺桿106將馬達108的旋轉運動轉換成直線運動，而使升降工作台76相對於基座架台78升降，藉此使配設有搬出入機構6之框體74在Z軸方向上移動。In the Z-axis moving mechanism 10, the ball screw 106 converts the rotational motion of the motor 108 into linear motion, so that the lifting table 76 is raised and lowered relative to the base frame 78, thereby moving the frame 74 equipped with the loading and unloading mechanism 6 in the Z-axis direction.

(X軸移動機構12) 參照圖8來說明，X軸移動機構12包含裝設於框體74之屈曲臂112、與使屈曲臂112作動之第一馬達114以及第二馬達115。屈曲臂112具有透過間隔件116擺動自如地連結於框體74的頂板部84的下表面之第一臂片118、與擺動自如地連結於第一臂片118的下表面之第二臂片120。 (X-axis moving mechanism 12) Referring to FIG. 8 , the X-axis moving mechanism 12 includes a flexure arm 112 mounted on the frame 74, and a first motor 114 and a second motor 115 for actuating the flexure arm 112. The flexure arm 112 has a first arm piece 118 movably connected to the lower surface of the top plate portion 84 of the frame 74 via a spacer 116, and a second arm piece 120 movably connected to the lower surface of the first arm piece 118.

間隔件116是配置於第一臂片118的一端部。第一臂片118是以間隔件116側作為擺動中心而連結於頂板部84。又，在第一臂片118的另一端部的上表面也設置有間隔件122。第二臂片120是以間隔件122側作為擺動中心而連結於第一臂片118。The spacer 116 is disposed at one end of the first arm piece 118. The first arm piece 118 is connected to the top plate portion 84 with the side of the spacer 116 as the swing center. A spacer 122 is also provided on the upper surface of the other end of the first arm piece 118. The second arm piece 120 is connected to the first arm piece 118 with the side of the spacer 122 as the swing center.

在第二臂片120的前端(與間隔件122為相反側之端部)設置有圓形孔(末圖示)。可在此圓形孔***搬出入機構6的Z旋轉軸46，且Z旋轉軸46呈無法旋轉地固定於第二臂片120。若驅動已連結於Z旋轉軸46之搬出入機構6的馬達時，搬出入機構6的罩殼52即相對於第二臂片120旋轉，且可將刀片保持部48以及固定螺帽保持部50定位到任意的方向。如此，搬出入機構6連結於X軸移動機構12的屈曲臂112，且透過屈曲臂112而配設於框體74。A circular hole (not shown) is provided at the front end of the second arm piece 120 (the end on the opposite side to the spacer 122). The Z rotating shaft 46 of the loading and unloading mechanism 6 can be inserted into this circular hole, and the Z rotating shaft 46 is fixed to the second arm piece 120 in a non-rotatable manner. When the motor of the loading and unloading mechanism 6 connected to the Z rotating shaft 46 is driven, the housing 52 of the loading and unloading mechanism 6 rotates relative to the second arm piece 120, and the blade holding part 48 and the fixing nut holding part 50 can be positioned in any direction. In this way, the loading and unloading mechanism 6 is connected to the flexure arm 112 of the X-axis moving mechanism 12, and is arranged on the frame 74 through the flexure arm 112.

在X軸移動機構12中，是形成為藉由第一馬達114，以間隔件116側作為擺動中心來使第一臂片118擺動，並且藉由第二馬達115，以間隔件122側作為擺動中心來使第二臂片120擺動，藉此使屈曲臂112屈曲或伸長，而使搬出入機構6朝X軸方向移動。In the X-axis moving mechanism 12, the first arm piece 118 is swung by the first motor 114 with the side of the spacer 116 as the swing center, and the second arm piece 120 is swung by the second motor 115 with the side of the spacer 122 as the swing center, thereby bending or extending the bending arm 112 and moving the loading and unloading mechanism 6 in the X-axis direction.

(讀取機構126) 如圖9所示，相鄰於搬出入機構6作用在切削刀片保管機構4之作用位置(可藉由搬出入機構6將已保管在切削刀片保管機構4之切削刀片搬出之位置)而配設有讀取機構126，前述讀取機構126會讀取已施加在被切削刀片保管機構4保管中的切削刀片的側面之表示種類的標示T。 (Reading mechanism 126) As shown in FIG9 , a reading mechanism 126 is provided adjacent to the position where the carrying-in/out mechanism 6 acts on the cutting blade storage mechanism 4 (a position where the cutting blade stored in the cutting blade storage mechanism 4 can be carried out by the carrying-in/out mechanism 6). The reading mechanism 126 reads the mark T indicating the type of the cutting blade applied to the side surface of the cutting blade stored in the cutting blade storage mechanism 4.

讀取機構126包含相機128、反射面相對於相機128的光軸傾斜了45度之鏡子130、以相機128的光軸為旋轉中心來使鏡子130旋轉之旋轉部132、與將鏡子130定位在作用位置與退避位置之定位部134。The reading mechanism 126 includes a camera 128, a mirror 130 whose reflective surface is tilted 45 degrees relative to the optical axis of the camera 128, a rotating part 132 for rotating the mirror 130 around the optical axis of the camera 128, and a positioning part 134 for positioning the mirror 130 at an active position and a retracted position.

(定位部134) 本實施形態的定位部134具備裝設於基座板26的上表面之殼體136、升降自如地支撐於殼體136之升降台138、及使升降台138升降之升降機構(未圖示)。升降機構亦可為空氣致動器或滾珠螺桿與馬達之組合。 (Positioning section 134) The positioning section 134 of this embodiment includes a housing 136 mounted on the upper surface of the base plate 26, a lifting platform 138 supported by the housing 136 so as to be able to be raised and lowered, and a lifting mechanism (not shown) for lifting and lowering the lifting platform 138. The lifting mechanism may also be an air actuator or a combination of a ball screw and a motor.

旋轉部132具有旋轉自如地附設在升降台138的上表面之旋轉工作台140、與以Z軸方向為軸心來使旋轉工作台140旋轉之馬達(未圖示)。在旋轉工作台140固定有相機128以及鏡子130。藉由旋轉部132的馬達，而形成為相機128以及鏡子130和旋轉工作台140一起旋轉。The rotating part 132 includes a rotating table 140 rotatably attached to the upper surface of the lifting platform 138, and a motor (not shown) for rotating the rotating table 140 with the Z-axis direction as the axis. The camera 128 and the mirror 130 are fixed to the rotating table 140. The motor of the rotating part 132 allows the camera 128 and the mirror 130 to rotate together with the rotating table 140.

(相機128、鏡子130) 相機128的光軸A(參照圖10)是和旋轉工作台140的旋轉中心一致。相機128是朝向配置在相機128的上方之鏡子130的反射面130a，且鏡子130的反射面130a是相對於相機128的光軸A傾斜45度。 (Camera 128, mirror 130) The optical axis A of the camera 128 (see FIG. 10) is consistent with the rotation center of the rotating table 140. The camera 128 is facing the reflection surface 130a of the mirror 130 disposed above the camera 128, and the reflection surface 130a of the mirror 130 is inclined 45 degrees relative to the optical axis A of the camera 128.

又，如圖10所示，鏡子130的反射面130a是定位成以45度的角度來和被切削刀片保管機構4保管中之切削刀片的第一側面相面對。又，鏡子130的反射面130a是定位成也以45度的角度來和藉由搬出入機構6所搬出之切削刀片的第二側面(與第一側面相反側之側面)相面對。再者，切削刀片的第一側面是指在被切削刀片保管機構4保管中之狀態下，朝向搬出入機構6側之面，且是被刀片保持部48所吸引保持之面。As shown in FIG. 10 , the reflective surface 130a of the mirror 130 is positioned to face the first side surface of the cutting blade stored in the cutting blade storage mechanism 4 at an angle of 45 degrees. Furthermore, the reflective surface 130a of the mirror 130 is positioned to face the second side surface (the side surface opposite to the first side surface) of the cutting blade carried out by the carrying-in and carrying-out mechanism 6 at an angle of 45 degrees. Furthermore, the first side surface of the cutting blade refers to the surface facing the carrying-in and carrying-out mechanism 6 side when the cutting blade is stored in the cutting blade storage mechanism 4, and is the surface attracted and held by the blade holding portion 48.

在可如上述地構成之讀取機構126中，是藉由以定位部134的升降機構使升降台138升降，而將鏡子130定位到上側作用位置與下側退避位置，其中前述上側作用位置是可用相機128透過鏡子130來拍攝切削刀片之位置，前述下側退避位置是鏡子130不會妨礙由搬出入機構6所進行之切削刀片的搬出/搬入之位置。In the reading mechanism 126 constructed as described above, the lifting platform 138 is raised and lowered by the lifting mechanism of the positioning part 134, so that the mirror 130 is positioned at the upper working position and the lower retreat position, wherein the upper working position is a position where the camera 128 can be used to photograph the cutting blade through the mirror 130, and the lower retreat position is a position where the mirror 130 will not hinder the carrying in/out of the cutting blade performed by the carrying in and out mechanism 6.

在鏡子130位於上側作用位置的狀態下，讀取機構126的相機128是透過鏡子130的反射面130a來拍攝切削刀片的第一側面或第二側面，並藉由所拍攝到的切削刀片的第一側面或第二側面的圖像，來讀取已施加在切削刀片的側面之表示種類的標示T。相機128所拍攝到的圖像亦可顯示於自動更換裝置2的監視器M，而且，亦可形成為將上述圖像保存於自動更換裝置2的記憶體。When the mirror 130 is in the upper working position, the camera 128 of the reading mechanism 126 photographs the first side or the second side of the cutting blade through the reflection surface 130a of the mirror 130, and reads the type-indicating mark T applied to the side of the cutting blade by the photographed image of the first side or the second side of the cutting blade. The image photographed by the camera 128 can also be displayed on the monitor M of the automatic changing device 2, and the above-mentioned image can also be stored in the memory of the automatic changing device 2.

其次，參照圖11至圖15來說明可供上述之自動更換裝置2連結之切削裝置170。Next, the cutting device 170 that can be connected to the above-mentioned automatic changing device 2 will be described with reference to FIGS. 11 to 15 .

(切削裝置170) 如圖11所示，切削裝置170具備：工作夾台172，具備有保持被加工物之保持面；切削機構174，以固定螺帽裝設有切削刀片，前述切削刀片對已保持在工作夾台172之被加工物進行切削；X軸進給機構176，使工作夾台172在X軸方向上加工進給；Y軸進給機構178，使切削機構174在和X軸方向正交之Y軸方向上分度進給；及Z軸進給機構180，使切削機構174在和X軸方向以及Y軸方向正交之Z軸方向上切入進給。 (Cutting device 170) As shown in FIG. 11, the cutting device 170 comprises: a work clamp 172 having a holding surface for holding a workpiece; a cutting mechanism 174 having a cutting blade mounted on a fixing nut, the cutting blade cutting the workpiece held on the work clamp 172; an X-axis feed mechanism 176 for feeding the work clamp 172 in the X-axis direction; a Y-axis feed mechanism 178 for indexing the cutting mechanism 174 in the Y-axis direction orthogonal to the X-axis direction; and a Z-axis feed mechanism 180 for cutting the cutting mechanism 174 in the Z-axis direction orthogonal to the X-axis direction and the Y-axis direction.

(工作夾台172) 參照圖11以及圖12來說明，切削裝置170具備在基台182(參照圖11)的上表面以在X軸方向上移動自如的方式設置之X軸可動板184、固定於X軸可動板184的上表面之支柱186、與固定於支柱186的上端之罩蓋板188。在罩蓋板188形成有圓形開口188a。工作夾台172是旋轉自如地搭載在支柱186的上端，且通過罩蓋板188的圓形開口188a而朝上方延伸。工作夾台172是藉由內置於支柱186之馬達(未圖示)而以Z軸方向作為軸心來旋轉。 (Working clamp 172) Referring to FIG. 11 and FIG. 12, the cutting device 170 includes an X-axis movable plate 184 provided on the upper surface of a base 182 (see FIG. 11) so as to be movable in the X-axis direction, a support 186 fixed to the upper surface of the X-axis movable plate 184, and a cover plate 188 fixed to the upper end of the support 186. A circular opening 188a is formed in the cover plate 188. The working clamp 172 is rotatably mounted on the upper end of the support 186 and extends upward through the circular opening 188a of the cover plate 188. The working clamp 172 is rotated with the Z-axis direction as the axis by a motor (not shown) built into the support 186.

如圖12所示，在工作夾台172的上端部分配置有已連接到吸引機構(未圖示)之多孔質的圓形狀的吸附夾頭190。在工作夾台172中形成為藉由以吸引機構在吸附夾頭190的上表面生成吸引力，而吸引保持已載置在吸附夾頭190的上表面之被加工物。As shown in FIG12, a porous circular suction chuck 190 connected to a suction mechanism (not shown) is disposed at the upper end portion of the work chuck 172. The work chuck 172 is formed so that the workpiece placed on the upper surface of the suction chuck 190 is attracted and held by the suction mechanism generating suction force on the upper surface of the suction chuck 190.

如此，在工作夾台172中，吸附夾頭190的上表面會成為保持被加工物之保持面，且保持面是定位在以X軸方向以及Y軸方向所規定之XY平面上。又，在工作夾台172的周緣，於圓周方向上隔著間隔而配置有複數個夾具192。Thus, in the work clamp 172, the upper surface of the suction chuck 190 becomes a holding surface for holding the workpiece, and the holding surface is positioned on an XY plane defined by the X-axis direction and the Y-axis direction. In addition, a plurality of clamps 192 are arranged at intervals in the circumferential direction around the work clamp 172.

(X軸進給機構176) 如圖12所示，X軸進給機構176具有連結於X軸可動板184並在X軸方向上延伸之滾珠螺桿198、與使滾珠螺桿198旋轉之馬達200。X軸進給機構176藉由滾珠螺桿198將馬達200的旋轉運動轉換成直線運動並傳達至X軸可動板184，使X軸可動板184沿著基台182的引導軌道182a移動，並且使工作夾台172在X軸方向上加工進給。 (X-axis feed mechanism 176) As shown in FIG. 12, the X-axis feed mechanism 176 has a ball screw 198 connected to the X-axis movable plate 184 and extending in the X-axis direction, and a motor 200 that rotates the ball screw 198. The X-axis feed mechanism 176 converts the rotational motion of the motor 200 into linear motion through the ball screw 198 and transmits it to the X-axis movable plate 184, so that the X-axis movable plate 184 moves along the guide rail 182a of the base 182, and the work clamp 172 is processed and fed in the X-axis direction.

如圖11所示，切削裝置170包含橫跨工作夾台172而配置之門型的框架202。框架202具有在Y軸方向上隔著間隔而從基台182的上表面朝上方延伸之一對支柱204、與橫跨架設在一對支柱204的上端間而在Y軸方向上延伸之樑206。As shown in Fig. 11, the cutting device 170 includes a door-shaped frame 202 disposed across the work clamp 172. The frame 202 includes a pair of pillars 204 extending upward from the upper surface of the base 182 at intervals in the Y-axis direction, and a beam 206 spanning between the upper ends of the pair of pillars 204 and extending in the Y-axis direction.

(切削機構174) 切削機構174是在樑206的單側的側面(在圖11中為背面側的側面)於Y軸方向上隔著間隔而設置有一對。在本實施形態之切削裝置170中，是以讓切削刀片相面對的方式而設置有一對切削機構174，且形成為可以藉由一對切削刀片同時地對已保持在工作夾台172之被加工物施行切削加工。再者，切削機構174亦可為1個。 (Cutting mechanism 174) A pair of cutting mechanisms 174 are provided on the side surface of one side of the beam 206 (the side surface of the back side in FIG. 11 ) at intervals in the Y-axis direction. In the cutting device 170 of this embodiment, a pair of cutting mechanisms 174 are provided in such a manner that the cutting blades face each other, and are formed so that the workpiece held on the work clamp 172 can be cut simultaneously by a pair of cutting blades. Furthermore, there may be one cutting mechanism 174.

如圖13所示，各切削機構174具備在Y軸方向上移動自如地支撐於樑206的單側的側面之矩形狀的Y軸可動構件208、在Z軸方向上升降自如地支撐於Y軸可動構件208之截面L字形的Z軸可動構件210、與固定在Z軸可動構件210的下端之主軸殼體212。As shown in Figure 13, each cutting mechanism 174 has a rectangular Y-axis movable component 208 supported on a single side of the beam 206 for free movement in the Y-axis direction, a Z-axis movable component 210 with an L-shaped cross-section supported on the Y-axis movable component 208 for free lifting and lowering in the Z-axis direction, and a spindle housing 212 fixed to the lower end of the Z-axis movable component 210.

在Y軸可動構件208的單側的側面(在圖13中為近前側的側面)，形成有在Z軸方向上隔著間隔而在Y軸方向上延伸之一對被引導溝208a，被引導溝208a以滑動自如的方式連結於一對引導軌道(未圖示)，前述一對引導軌道在樑206的單側的側面且在上下方向上隔著間隔而在Y軸方向上延伸。On one side of the Y-axis movable component 208 (the side near the front side in Figure 13), a pair of guided grooves 208a are formed, which extend in the Y-axis direction with a gap in the Z-axis direction. The guided grooves 208a are connected to a pair of guide rails (not shown) in a slidable manner. The pair of guide rails are on one side of the beam 206 and extend in the Y-axis direction with a gap in the up and down directions.

(Y軸進給機構178) Y軸進給機構178具有在樑206的單側的側面且在Y軸方向上延伸之滾珠螺桿214、與使滾珠螺桿214旋轉之馬達216。滾珠螺桿214已連結於Y軸可動構件208。Y軸進給機構178是藉由滾珠螺桿214將馬達216的旋轉運動轉換成直線運動並傳達至Y軸可動構件208，而將Y軸可動構件208沿著附設於樑206的單側的側面之引導軌道在Y軸方向上分度進給。 (Y-axis feed mechanism 178) The Y-axis feed mechanism 178 has a ball screw 214 extending in the Y-axis direction on the side surface of one side of the beam 206, and a motor 216 for rotating the ball screw 214. The ball screw 214 is connected to the Y-axis movable member 208. The Y-axis feed mechanism 178 converts the rotational motion of the motor 216 into linear motion by the ball screw 214 and transmits it to the Y-axis movable member 208, thereby indexing and feeding the Y-axis movable member 208 in the Y-axis direction along the guide rail attached to the side surface of one side of the beam 206.

在Y軸可動構件208的另一側的側面(在圖13中為背面側的側面)形成有在Y軸方向上隔著間隔而在Z軸方向上延伸之一對引導軌道(未圖示)，Z軸可動構件210具有滑動自如地連結於Y軸可動構件208的一對引導軌道之一對被引導溝(未圖示)。A pair of guide rails (not shown) are formed on the other side of the Y-axis movable component 208 (the back side in FIG. 13 ) and extend in the Z-axis direction with intervals therebetween. The Z-axis movable component 210 has a pair of guided grooves (not shown) that are slidably connected to the pair of guide rails of the Y-axis movable component 208.

(Z軸進給機構180) Z軸進給機構180具有連結於Z軸可動構件210且在Z軸方向上延伸之滾珠螺桿(未圖示)、與使此滾珠螺桿旋轉之馬達218。Z軸進給機構180是藉由滾珠螺桿將馬達218的旋轉運動轉換成直線運動並傳達至Z軸可動構件210，而讓Z軸可動構件210沿著Y軸可動構件208的引導軌道朝Z軸方向切入進給。 (Z-axis feed mechanism 180) The Z-axis feed mechanism 180 has a ball screw (not shown) connected to the Z-axis movable member 210 and extending in the Z-axis direction, and a motor 218 that rotates the ball screw. The Z-axis feed mechanism 180 converts the rotational motion of the motor 218 into linear motion through the ball screw and transmits it to the Z-axis movable member 210, so that the Z-axis movable member 210 cuts and feeds in the Z-axis direction along the guide rail of the Y-axis movable member 208.

參照圖14來說明，在主軸殼體212中以Y軸方向作為軸心而旋轉自如地支撐有圓柱狀的主軸220，並且容置有使主軸220旋轉之馬達(未圖示)。在主軸220的前端，藉由固定螺帽222而裝卸自如地固定有切削被加工物之切削刀片。再者，在圖14中所顯示的是已將輪轂型刀片36作為切削刀片固定於主軸220的例子。Referring to FIG. 14 , a cylindrical spindle 220 is rotatably supported in the spindle housing 212 with the Y-axis direction as the axis, and a motor (not shown) for rotating the spindle 220 is accommodated. A cutting blade for cutting a workpiece is detachably fixed to the front end of the spindle 220 by a fixing nut 222. FIG. 14 shows an example in which a hub-type blade 36 is fixed to the spindle 220 as a cutting blade.

主軸殼體212的前端裝設有覆蓋切削刀片之刀片蓋224。刀片蓋224具有固定於主軸殼體212的前端之第一罩蓋構件224a、與移動自如地裝設在第一罩蓋構件224a的前端之第二罩蓋構件224b。第二罩蓋構件224b形成為可藉由氣缸等之合宜的致動器(未圖示)而在X軸方向上移動，且在切削刀片的更換時是定位在圖14所示之開放位置，在切削加工時則是定位在圖13所示之封閉位置。A blade cover 224 covering the cutting blade is installed at the front end of the spindle housing 212. The blade cover 224 has a first cover member 224a fixed to the front end of the spindle housing 212, and a second cover member 224b movably installed at the front end of the first cover member 224a. The second cover member 224b is formed to be movable in the X-axis direction by a suitable actuator (not shown) such as a cylinder, and is positioned in the open position shown in FIG. 14 when the cutting blade is replaced, and is positioned in the closed position shown in FIG. 13 during cutting processing.

如圖15所示，在主軸220的前端側外周面設置有朝徑方向外側突出之環狀的固定凸緣226。在固定凸緣226的前端面的徑方向內側部分形成有環狀的凹處226a，固定凸緣226的前端面的外周側部分是成為朝軸方向突出之環狀的支撐端面226b。又，在主軸220之比固定凸緣226更前端側的外周面形成有公螺絲228。As shown in FIG. 15 , an annular fixing flange 226 protruding outward in the radial direction is provided on the outer peripheral surface of the front end side of the main shaft 220. An annular recess 226a is formed on the radial inner side portion of the front end surface of the fixing flange 226, and the outer peripheral side portion of the front end surface of the fixing flange 226 is an annular support end surface 226b protruding in the axial direction. In addition, a male screw 228 is formed on the outer peripheral surface of the main shaft 220 on the front end side of the fixing flange 226.

並且，在將輪轂型刀片36作為切削刀片裝設於主軸220的情況下，藉由將輪轂型刀片36的中央開口部38a嵌合於主軸220的前端部，且螺接(緊固)主軸220的公螺絲228與固定螺帽222，輪轂型刀片36會被固定凸緣226的支撐端面226b與固定螺帽222夾入，而呈裝卸自如地固定在主軸220的前端。又，在固定螺帽222的側面，在圓周方向上隔著等間隔而形成有複數個銷孔222a，前述銷孔222a可供搬出入機構6的固定螺帽保持部50的銷72***。Furthermore, when the hub-type insert 36 is mounted on the spindle 220 as a cutting insert, the central opening 38a of the hub-type insert 36 is fitted into the front end of the spindle 220, and the male screw 228 and the fixing nut 222 of the spindle 220 are screwed (fastened), so that the hub-type insert 36 is sandwiched between the supporting end surface 226b of the fixing flange 226 and the fixing nut 222, and is fixed to the front end of the spindle 220 in a detachable manner. In addition, a plurality of pin holes 222a are formed at equal intervals in the circumferential direction on the side surface of the fixing nut 222, and the pins 72 of the fixing nut holding portion 50 of the loading and unloading mechanism 6 are inserted into the pin holes 222a.

又，在將墊圈型刀片45作為切削刀片裝設於主軸220的情況下，如圖16所示，是在墊圈型刀片45已被夾入固定凸緣226的支撐端面226b與環狀的裝設凸緣229的狀態下，藉由螺接(緊固)主軸220的公螺絲228與固定螺帽222，來將墊圈型刀片45裝卸自如地固定於主軸220的前端。Furthermore, when the washer-type blade 45 is installed on the spindle 220 as a cutting blade, as shown in Figure 16, the washer-type blade 45 has been clamped between the supporting end face 226b of the fixing flange 226 and the annular mounting flange 229, and the washer-type blade 45 is fixed to the front end of the spindle 220 in a freely loadable and removable manner by screwing (tightening) the male screw 228 and the fixing nut 222 of the spindle 220.

再者，在裝設凸緣229的背面設置有環狀的突出部229a，前述環狀的突出部229a具有和墊圈型刀片45的中央開口部45a的內徑對應之外徑D(和切削刀片保管機構4的軸部34的外徑D相同)。並且，在將墊圈型刀片45固定於主軸220時，是將墊圈型刀片45的中央開口部45a嵌合於突出部229a。Furthermore, an annular protrusion 229a is provided on the back side of the mounting flange 229, and the annular protrusion 229a has an outer diameter D corresponding to the inner diameter of the central opening 45a of the washer-type blade 45 (the same as the outer diameter D of the shaft 34 of the cutting blade storage mechanism 4). When the washer-type blade 45 is fixed to the spindle 220, the central opening 45a of the washer-type blade 45 is fitted into the protrusion 229a.

如圖11所示，在框架202的樑206的另一側的側面(在圖11中為近前側的側面)以在Y軸方向上移動自如的方式裝設有對已保持在工作夾台172之被加工物進行拍攝之一對拍攝機構230，並且裝設有使拍攝機構230在Y軸方向上移動之一對移動機構232。As shown in FIG11 , a pair of photographing mechanisms 230 for photographing the workpiece held on the work clamp 172 are installed on the side surface of the other side of the beam 206 of the frame 202 (the side surface near the front side in FIG11 ) so as to be freely movable in the Y-axis direction, and a pair of moving mechanisms 232 are installed so as to move the photographing mechanisms 230 in the Y-axis direction.

移動機構232具有在樑206的另一側的側面且在Y軸方向上延伸之滾珠螺桿234、與使滾珠螺桿234旋轉之馬達236。滾珠螺桿234已連結於拍攝機構230。並且，移動機構232是將馬達236的旋轉運動轉換成直線運動並傳達至拍攝機構230，使拍攝機構230沿著附設於樑206的另一側的側面之引導軌道206a在Y軸方向上移動。再者，拍攝機構230亦可為1個。The moving mechanism 232 has a ball screw 234 extending in the Y-axis direction on the side surface of the other side of the beam 206, and a motor 236 for rotating the ball screw 234. The ball screw 234 is connected to the shooting mechanism 230. In addition, the moving mechanism 232 converts the rotational motion of the motor 236 into a linear motion and transmits it to the shooting mechanism 230, so that the shooting mechanism 230 moves in the Y-axis direction along the guide rail 206a attached to the side surface of the other side of the beam 206. In addition, the shooting mechanism 230 can also be one.

(切削加工) 在使用切削裝置170來對晶圓等之被加工物施行切削加工時，首先是使工作夾台172吸附被加工物。接著，以X軸進給機構176使工作夾台172移動至拍攝機構230的下方，並且以移動機構232調整拍攝機構230的Y軸方向位置。接著，以拍攝機構230從上方拍攝被加工物來檢測被加工物的切削區域。 (Cutting) When using the cutting device 170 to perform cutting on a workpiece such as a wafer, the workpiece is firstly adsorbed by the workpiece 172. Then, the workpiece 172 is moved to the bottom of the photographing mechanism 230 by the X-axis feed mechanism 176, and the Y-axis position of the photographing mechanism 230 is adjusted by the moving mechanism 232. Then, the photographing mechanism 230 photographs the workpiece from above to detect the cutting area of the workpiece.

接著，依據以拍攝機構230所檢測出之被加工物的切削區域，使工作夾台172旋轉，來調整被加工物的切削區域相對於切削機構174的切削刀片之方向。接著，以X軸進給機構176使工作夾台172在X軸方向上移動，並且以Y軸進給機構178使主軸殼體212在Y軸方向上移動，而將一對切削刀片定位到被加工物的切削區域的上方。Next, the worktable 172 is rotated according to the cutting area of the workpiece detected by the camera mechanism 230 to adjust the direction of the cutting area of the workpiece relative to the cutting blade of the cutting mechanism 174. Next, the worktable 172 is moved in the X-axis direction by the X-axis feed mechanism 176, and the spindle housing 212 is moved in the Y-axis direction by the Y-axis feed mechanism 178, so that a pair of cutting blades are positioned above the cutting area of the workpiece.

接著，以Z軸進給機構180使主軸殼體212下降，使已高速旋轉之切削刀片的切刃切入被加工物的切削區域，並且一邊對已切入切削刀片的切刃之部分供給切削水一邊將工作夾台172在X軸方向上加工進給，藉此對被加工物的切削區域施行預定的切削加工。一邊以Y軸進給機構178將主軸殼體212在Y軸方向上分度進給，一邊合宜地重複上述切削加工，而對被加工物的整個切削區域施行切削加工。已結束切削步驟之切削加工完畢之被加工物會被搬送至下一個步驟。Next, the Z-axis feed mechanism 180 lowers the spindle housing 212, so that the cutting edge of the cutting blade that has been rotating at a high speed cuts into the cutting area of the workpiece, and while supplying cutting water to the portion of the cutting edge of the cutting blade that has been cut into, the work clamp 172 is fed in the X-axis direction, thereby performing a predetermined cutting process on the cutting area of the workpiece. While the Y-axis feed mechanism 178 indexes the spindle housing 212 in the Y-axis direction, the above-mentioned cutting process is appropriately repeated, and the entire cutting area of the workpiece is cut. The workpiece that has completed the cutting process of the cutting step will be transported to the next step.

(切削刀片的更換) 因為若重複實施切削步驟，切削刀片會磨耗，且若切削刀片的磨耗到達預定量時會變得無法維持切削精度，所以必須將已裝設於主軸220之切削刀片更換為新的切削刀片。又，即便在已裝設於主軸220之切削刀片的磨耗尚未到達預定量的情況下，在對與之前施行切削加工之被加工物的素材不同的素材之被加工物施行切削加工時，也必須更換為和被加工物的素材相應之切削刀片。 (Replacement of cutting blade) If the cutting steps are repeated, the cutting blade will wear out, and if the wear of the cutting blade reaches a predetermined amount, it will become impossible to maintain the cutting accuracy, so the cutting blade installed on the spindle 220 must be replaced with a new cutting blade. Moreover, even if the wear of the cutting blade installed on the spindle 220 has not reached the predetermined amount, when cutting a workpiece of a material different from the material of the workpiece previously cut, it is necessary to replace it with a cutting blade corresponding to the material of the workpiece.

在本實施形態中，是如圖17所示，已將可以自動地更換切削裝置170的切削刀片之自動更換裝置2連結於切削裝置170，以下針對使用自動更換裝置2來更換輪轂型刀片36之方法進行說明。In the present embodiment, as shown in FIG. 17 , an automatic replacement device 2 for automatically replacing the cutting blade of the cutting device 170 is connected to the cutting device 170. The following is a description of a method for replacing the hub-type blade 36 using the automatic replacement device 2.

如圖17所示，自動更換裝置2是配置在切削裝置170的X軸方向後側，且形成為可以在之後裝設到已經交貨給使用者之切削裝置170。As shown in FIG. 17 , the automatic replacement device 2 is disposed on the rear side of the cutting device 170 in the X-axis direction, and is formed so as to be installed later on the cutting device 170 that has been delivered to the user.

使用自動更換裝置2來更換已裝設在切削裝置170之輪轂型刀片36時，首先是使切削刀片保管機構4的無端軌道22旋轉，並將支撐有用來搬入切削裝置170之新的輪轂型刀片36之刀片支撐軸24定位在預定位置(例如刀片支撐軸24的軌道中的最下端的位置)。When using the automatic replacement device 2 to replace the hub-type blade 36 installed in the cutting device 170, the endless track 22 of the cutting blade storage mechanism 4 is first rotated, and the blade support shaft 24 supporting the new hub-type blade 36 used to move into the cutting device 170 is positioned at a predetermined position (for example, the lowest position in the track of the blade support shaft 24).

接著，藉由讀取機構126來確認已定位在上述預定位置之輪轂型刀片36的種類，是否和應搬入切削裝置170之輪轂型刀片36的種類一致。此時，首先是藉由定位部134使升降台138上升，而將鏡子130定位到可藉相機128透過鏡子130來拍攝輪轂型刀片36之上側作用位置。Next, the reading mechanism 126 is used to confirm whether the type of the hub blade 36 positioned at the predetermined position is consistent with the type of the hub blade 36 to be carried into the cutting device 170. At this time, the lifting platform 138 is first raised by the positioning unit 134, and the mirror 130 is positioned to the upper side of the hub blade 36 through the mirror 130 by the camera 128.

又，在鏡子130的反射面130a未朝向切削刀片保管機構4的情況下，是藉由旋轉部132使鏡子130與旋轉工作台140一起旋轉，而讓鏡子130的反射面130a朝向切削刀片保管機構4。Furthermore, when the reflective surface 130 a of the mirror 130 is not facing the cutting insert storage mechanism 4 , the mirror 130 is rotated together with the rotary table 140 by the rotating portion 132 so that the reflective surface 130 a of the mirror 130 faces the cutting insert storage mechanism 4 .

接著，藉由相機128透過鏡子130的反射面130a來拍攝輪轂型刀片36的第一側面(朝向搬出入機構6側之面)。然後，如圖10所示，藉由所拍攝到之輪轂型刀片36的第一側面的圖像，來讀取施加於輪轂型刀片36的側面之表示種類的標示T(例如A005)。Next, the camera 128 photographs the first side surface (the surface facing the loading and unloading mechanism 6) of the hub blade 36 through the reflective surface 130a of the mirror 130. Then, as shown in FIG. 10 , the mark T (e.g., A005) indicating the type applied to the side surface of the hub blade 36 is read out by the image of the first side surface of the hub blade 36 photographed.

然後，在從所讀取到之標示T讀取到之定位於上述預定位置之輪轂型刀片36的種類，和應搬入切削裝置170之輪轂型刀片36的種類不一致的情況下，為了向操作人員通知該意旨，會使自動更換裝置2的警報(未圖示)、或自動更換裝置2的旋轉燈等的照明機構(未圖示)作動。Then, when the type of the hub-type blade 36 positioned at the above-mentioned predetermined position read from the mark T is inconsistent with the type of the hub-type blade 36 to be moved into the cutting device 170, in order to notify the operator of this intention, the alarm of the automatic changing device 2 (not shown) or the lighting mechanism such as the rotating light of the automatic changing device 2 (not shown) will be activated.

另一方面，在定位在上述預定位置之輪轂型刀片36的種類，和應搬入切削裝置170之輪轂型刀片36的種類是一致的情況下，會藉由定位部134使升降台138下降，而將鏡子130定位到不會有鏡子130妨礙由搬出入機構6所進行之切削刀片的搬出/搬入之情形的下側退避位置。On the other hand, when the type of the hub-type blade 36 positioned at the above-mentioned predetermined position is consistent with the type of the hub-type blade 36 to be carried into the cutting device 170, the lifting platform 138 is lowered by the positioning portion 134, and the mirror 130 is positioned to the lower retreat position where the mirror 130 will not interfere with the carrying in/out of the cutting blade performed by the carrying in and out mechanism 6.

如此進行而以讀取機構126讀取輪轂型刀片36的種類，並完成輪轂型刀片36的種類之確認後，即如圖18所示，以已連結於搬出入機構6的Z旋轉軸46之馬達使罩殼52旋轉，使裝設有刀片保持部48之罩殼52的側壁56沿著X軸方向，而使刀片保持部48面對切削刀片保管機構4。In this way, the reading mechanism 126 reads the type of the hub-type blade 36, and after completing the confirmation of the type of the hub-type blade 36, as shown in Figure 18, the motor connected to the Z rotating shaft 46 of the loading and unloading mechanism 6 rotates the shell 52, so that the side wall 56 of the shell 52 equipped with the blade holding part 48 is rotated along the X-axis direction, and the blade holding part 48 faces the cutting blade storage mechanism 4.

又，作動X軸移動機構12以及Z軸移動機構10，以將刀片保持部48的X軸方向位置以及Z軸方向位置調整成可以將上述預定位置的刀片支撐軸24的軸部34***刀片保持部48的中央開口部60(參照圖6)。In addition, the X-axis moving mechanism 12 and the Z-axis moving mechanism 10 are actuated to adjust the X-axis position and the Z-axis position of the blade holding portion 48 so that the shaft portion 34 of the blade supporting shaft 24 at the above-mentioned predetermined position can be inserted into the central opening portion 60 of the blade holding portion 48 (refer to Figure 6).

接著，如圖19所示，藉由Y軸移動機構8使框體74在Y軸方向上移動，將搬出入機構6定位到可藉由刀片保持部48來保持被刀片支撐軸24支撐中的輪轂型刀片36之作用位置。藉此，將上述預定位置的刀片支撐軸24的軸部34***刀片保持部48的中央開口部60，並且使刀片保持部48的端面58和位於軸部34的前端側之輪轂型刀片36的端面相接。接著，在刀片保持部48的第一吸引孔61生成吸引力，而以刀片保持部48吸引保持位於軸部34的前端側之輪轂型刀片36。Next, as shown in FIG. 19 , the frame 74 is moved in the Y-axis direction by the Y-axis moving mechanism 8, and the loading and unloading mechanism 6 is positioned to the action position where the hub-type blade 36 supported by the blade support shaft 24 can be held by the blade holding portion 48. Thus, the shaft portion 34 of the blade support shaft 24 at the predetermined position is inserted into the central opening 60 of the blade holding portion 48, and the end face 58 of the blade holding portion 48 is brought into contact with the end face of the hub-type blade 36 located at the front end side of the shaft portion 34. Then, suction is generated in the first suction hole 61 of the blade holding portion 48, and the hub-type blade 36 located at the front end side of the shaft portion 34 is suctioned and held by the blade holding portion 48.

接著，使Y軸移動機構8作動，來使搬出入機構6從切削刀片保管機構4朝Y軸方向拉開間隔並定位到退避位置。接著，使搬出入機構6的罩殼52旋轉180°，而使吸引保持有輪轂型刀片36之刀片保持部48的相反側的刀片保持部48面對切削刀片保管機構4。Next, the Y-axis moving mechanism 8 is actuated to move the loading and unloading mechanism 6 away from the cutting blade storage mechanism 4 in the Y-axis direction and positioned at the retracted position. Next, the housing 52 of the loading and unloading mechanism 6 is rotated 180 degrees, so that the blade holding portion 48 on the opposite side of the blade holding portion 48 that attracts and holds the hub-type blade 36 faces the cutting blade storage mechanism 4.

接著，使Y軸移動機構8作動，而將搬出入機構6定位到可藉由相反側的刀片保持部48來保持刀片支撐軸24的輪轂型刀片36之作用位置。接著，在相反側的刀片保持部48的第一吸引孔61生成吸引力，而藉由刀片保持部48來吸引保持位於軸部34的前端側之輪轂型刀片36。藉此，成為以4個刀片保持部48當中相向之一對刀片保持部48吸引保持有新的輪轂型刀片36之狀態。Next, the Y-axis moving mechanism 8 is actuated to position the loading and unloading mechanism 6 to a position where the blade holding portion 48 on the opposite side can hold the hub blade 36 of the blade support shaft 24. Next, suction is generated in the first suction hole 61 of the blade holding portion 48 on the opposite side, and the hub blade 36 located at the front end side of the shaft portion 34 is suctioned and held by the blade holding portion 48. Thus, a new hub blade 36 is suctioned and held by one of the four blade holding portions 48 facing each other.

再者，因為對相同的刀片支撐軸24，應該支撐有相同種類的輪轂型刀片36，所以亦可省略輪轂型刀片36的種類之確認，但亦可在以相反側的刀片保持部48來吸引保持輪轂型刀片36之前，藉由讀取機構126來確認輪轂型刀片36的種類。Furthermore, since the same blade support shaft 24 should support the same type of hub-type blade 36, the confirmation of the type of the hub-type blade 36 can be omitted, but the type of the hub-type blade 36 can be confirmed by the reading mechanism 126 before the blade holding portion 48 on the opposite side attracts and holds the hub-type blade 36.

在已藉由一對刀片保持部48吸引保持新的輪轂型刀片36後，如圖20所示，藉由Y軸移動機構8使框體74在Y軸方向上移動，並且以Z軸移動機構10使升降工作台76在Z軸方向上移動。藉此，使搬出入機構6從切削刀片保管機構4拉開間隔並定位到退避位置，並且調整搬出入機構6相對於切削裝置170之Y軸方向位置以及Z軸方向位置。位置調整後之搬出入機構6的Y軸方向位置是在切削裝置170的一對切削機構174之間，且位置調整後之搬出入機構6的Z軸方向位置在比工作夾台172的保持面更上方。After the new hub-type blade 36 is attracted and held by a pair of blade holding portions 48, as shown in FIG. 20, the frame 74 is moved in the Y-axis direction by the Y-axis moving mechanism 8, and the lifting table 76 is moved in the Z-axis direction by the Z-axis moving mechanism 10. In this way, the loading and unloading mechanism 6 is spaced from the cutting blade storage mechanism 4 and positioned to a retreat position, and the Y-axis direction position and Z-axis direction position of the loading and unloading mechanism 6 relative to the cutting device 170 are adjusted. The Y-axis direction position of the loading and unloading mechanism 6 after the position adjustment is between the pair of cutting mechanisms 174 of the cutting device 170, and the Z-axis direction position of the loading and unloading mechanism 6 after the position adjustment is above the holding surface of the work clamp 172.

接著，如圖21所示，藉由X軸移動機構12使搬出入機構6在X軸方向上移動，來調整搬出入機構6相對於一對切削機構174之X軸方向位置。具體而言，是使以搬出入機構6的一對刀片保持部48所吸引保持之新的一對輪轂型刀片36的中心的X軸方向位置、與已裝設於一對切削機構174之一對輪轂型刀片36的中心的X軸方向位置對齊。Next, as shown in FIG. 21 , the X-axis moving mechanism 12 moves the carrying-in/out mechanism 6 in the X-axis direction to adjust the X-axis direction position of the carrying-in/out mechanism 6 relative to the pair of cutting mechanisms 174. Specifically, the X-axis direction position of the center of the new pair of hub-shaped blades 36 attracted and held by the pair of blade holding portions 48 of the carrying-in/out mechanism 6 is aligned with the X-axis direction position of the center of the pair of hub-shaped blades 36 installed in the pair of cutting mechanisms 174.

又，使自動更換裝置2的Z軸移動機構10或切削裝置170的Z軸進給機構180作動，來讓刀片保持部48的輪轂型刀片36的中心的Z軸方向位置、與切削機構174的輪轂型刀片36的中心的Z軸方向位置對齊。In addition, the Z-axis moving mechanism 10 of the automatic changing device 2 or the Z-axis feeding mechanism 180 of the cutting device 170 is operated to align the Z-axis direction position of the center of the hub-type blade 36 of the blade holding portion 48 with the Z-axis direction position of the center of the hub-type blade 36 of the cutting mechanism 174.

接著，使搬出入機構6的罩殼52旋轉60°，使一對固定螺帽保持部50面對一對切削機構174的輪轂型刀片36。再者，亦可在使搬出入機構6前進之前，使罩殼52旋轉60°。Next, the housing 52 of the carrying-in/out mechanism 6 is rotated 60° so that the pair of fixed nut holding portions 50 face the pair of hub-shaped blades 36 of the cutting mechanism 174. Furthermore, the housing 52 may be rotated 60° before the carrying-in/out mechanism 6 is advanced.

接著，將一對切削機構174的各個的刀片蓋224的第二罩蓋構件224b定位到開放位置(參照圖14)。接著，藉由切削裝置170的Y軸進給機構178使切削機構174在Y軸方向上移動，使已將輪轂型刀片36固定於主軸220之固定螺帽222接觸於固定螺帽保持部50的旋轉體66的端面66a。如此一來，固定螺帽保持部50的銷72會被固定螺帽222按壓而容置到旋轉體66的內部，並且主軸220的前端會容置於旋轉體66的中央開口部68。Next, the second cover member 224b of each blade cover 224 of the pair of cutting mechanisms 174 is positioned at the open position (refer to FIG. 14 ). Next, the cutting mechanism 174 is moved in the Y-axis direction by the Y-axis feed mechanism 178 of the cutting device 170, so that the fixing nut 222 that has fixed the hub-type blade 36 to the spindle 220 contacts the end face 66a of the rotating body 66 of the fixing nut holding part 50. In this way, the pin 72 of the fixing nut holding part 50 is pressed by the fixing nut 222 and accommodated in the inside of the rotating body 66, and the front end of the spindle 220 is accommodated in the central opening 68 of the rotating body 66.

接著，當以固定螺帽保持部50的馬達使旋轉體66旋轉後，在各銷72和固定螺帽222的銷孔222a一致時，各銷72會嵌合於銷孔222a，且旋轉體66的旋轉運動會透過各銷72傳達至固定螺帽222，使固定螺帽222鬆開。藉此，可以從切削機構174的主軸220的公螺絲228將固定螺帽222螺鬆(取下)。又，在固定螺帽保持部50的各吸引孔70生成吸引力，而以固定螺帽保持部50吸引保持已取下之固定螺帽222。Next, when the motor of the fixed nut holding part 50 rotates the rotating body 66, when the pins 72 and the pin holes 222a of the fixed nut 222 are aligned, the pins 72 are fitted into the pin holes 222a, and the rotational movement of the rotating body 66 is transmitted to the fixed nut 222 through the pins 72, so that the fixed nut 222 is loosened. In this way, the fixed nut 222 can be loosened (removed) from the male screw 228 of the main shaft 220 of the cutting mechanism 174. In addition, the suction holes 70 of the fixed nut holding part 50 generate suction force, and the fixed nut holding part 50 sucks and holds the removed fixed nut 222.

接著，藉由Y軸進給機構178使切削機構174從搬出入機構6拉開間隔，並且使搬出入機構6的罩殼52旋轉60°，使未吸引保持有輪轂型刀片36之空的刀片保持部48面對切削機構174的輪轂型刀片36。Next, the cutting mechanism 174 is spaced apart from the carrying-in/out mechanism 6 by the Y-axis feed mechanism 178, and the cover shell 52 of the carrying-in/out mechanism 6 is rotated 60° so that the empty blade holding portion 48 that does not attract and hold the hub-type blade 36 faces the hub-type blade 36 of the cutting mechanism 174.

接著，藉由Y軸進給機構178使切削機構174朝搬出入機構6接近，來將切削機構174的主軸220***刀片保持部48的中央開口部60，並且使空的刀片保持部48的端面58接觸於切削機構174的輪轂型刀片36的端面。接著，在刀片保持部48的第一吸引孔61生成吸引力，而以刀片保持部48吸引保持切削機構174的輪轂型刀片36。Next, the cutting mechanism 174 is brought close to the loading and unloading mechanism 6 by the Y-axis feeding mechanism 178, so that the spindle 220 of the cutting mechanism 174 is inserted into the central opening 60 of the blade holding portion 48, and the end face 58 of the empty blade holding portion 48 is brought into contact with the end face of the hub-type blade 36 of the cutting mechanism 174. Then, suction is generated in the first suction hole 61 of the blade holding portion 48, and the hub-type blade 36 of the cutting mechanism 174 is held by suction by the blade holding portion 48.

接著，藉由Y軸進給機構178使切削機構174從搬出入機構6拉開間隔，並且使搬出入機構6的罩殼52旋轉60°，而使吸引保持有新的輪轂型刀片36之刀片保持部48面對切削機構174的主軸220。Next, the cutting mechanism 174 is spaced apart from the loading and unloading mechanism 6 by the Y-axis feed mechanism 178, and the housing 52 of the loading and unloading mechanism 6 is rotated 60° so that the blade holding portion 48 that attracts and holds the new hub-type blade 36 faces the main shaft 220 of the cutting mechanism 174.

接著，藉由Y軸進給機構178使切削機構174朝搬出入機構6接近，來將主軸220***到新的輪轂型刀片36的中央開口部38a，且使輪轂型刀片36的端面接觸於主軸220的固定凸緣226的支撐端面226b。接著，解除刀片保持部48的吸引力，將新的輪轂型刀片36從刀片保持部48交接至主軸220。Next, the cutting mechanism 174 is moved toward the loading and unloading mechanism 6 by the Y-axis feeding mechanism 178, so that the spindle 220 is inserted into the central opening 38a of the new hub-type blade 36, and the end surface of the hub-type blade 36 is brought into contact with the supporting end surface 226b of the fixed flange 226 of the spindle 220. Next, the attraction of the blade holding portion 48 is released, and the new hub-type blade 36 is transferred from the blade holding portion 48 to the spindle 220.

接著，藉由Y軸進給機構178使切削機構174從搬出入機構6拉開間隔，並且使搬出入機構6的罩殼52旋轉60°，使吸引保持有已取下之固定螺帽222的固定螺帽保持部50面對切削機構174的主軸220。Next, the cutting mechanism 174 is spaced apart from the loading and unloading mechanism 6 by the Y-axis feed mechanism 178, and the cover 52 of the loading and unloading mechanism 6 is rotated 60° so that the fixing nut holding part 50 that attracts and holds the removed fixing nut 222 faces the main shaft 220 of the cutting mechanism 174.

接著，藉由Y軸進給機構178使切削機構174朝搬出入機構6接近，使以固定螺帽保持部50所吸引保持之固定螺帽222嵌合於主軸220的前端部。接著，使固定螺帽保持部50的馬達朝和取下固定螺帽222時為相反之方向作動來讓固定螺帽222旋轉，而將固定螺帽222螺接(緊固)於主軸220的公螺絲228。Next, the cutting mechanism 174 is moved toward the loading and unloading mechanism 6 by the Y-axis feeding mechanism 178, so that the fixing nut 222 attracted and held by the fixing nut holding portion 50 is engaged with the front end portion of the spindle 220. Next, the motor of the fixing nut holding portion 50 is operated in the opposite direction to that when the fixing nut 222 is removed, so that the fixing nut 222 is rotated, and the fixing nut 222 is screwed (fastened) to the male screw 228 of the spindle 220.

藉此，可以將用來裝設於切削機構174之新的輪轂型刀片36以主軸220的固定凸緣226的支撐端面226b與固定螺帽222來夾入而固定於主軸220。Thereby, the new hub-type blade 36 to be installed in the cutting mechanism 174 can be fixed to the main shaft 220 by clamping it with the supporting end surface 226b of the fixing flange 226 of the main shaft 220 and the fixing nut 222.

接著，在解除固定螺帽保持部50的吸引力後，將切削機構174的刀片蓋224的第二罩蓋構件224b定位到封閉位置。再者，關於如上述之固定螺帽222以及輪轂型刀片36的取下、安裝，可對一對切削機構174同時進行，亦可個別地進行。Then, after removing the attraction of the fixing nut holding portion 50, the second cover member 224b of the blade cover 224 of the cutting mechanism 174 is positioned to the closed position. Furthermore, the removal and installation of the fixing nut 222 and the hub-shaped blade 36 as described above can be performed simultaneously for a pair of cutting mechanisms 174 or individually.

接著，使搬出入機構6後退，並且使搬出入機構6的罩殼52旋轉60°，來讓已取下之一對輪轂型刀片36的其中一個與切削刀片保管機構4面對。又，使切削刀片保管機構4的無端軌道22旋轉，而將未支撐有輪轂型刀片36之空的刀片支撐軸24定位到預定位置(例如刀片支撐軸24在軌道中的最下端的位置)。Next, the loading and unloading mechanism 6 is retracted, and the housing 52 of the loading and unloading mechanism 6 is rotated 60 degrees, so that one of the removed pair of hub-type blades 36 faces the cutting blade storage mechanism 4. Furthermore, the endless track 22 of the cutting blade storage mechanism 4 is rotated, and the empty blade support shaft 24 that does not support the hub-type blade 36 is positioned at a predetermined position (for example, the lowermost position of the blade support shaft 24 in the track).

接著，作動X軸移動機構12以及Z軸移動機構10，將刀片保持部48的X軸方向位置以及Z軸方向位置調整成可以將上述預定位置的刀片支撐軸24的軸部34***以刀片保持部48所吸引保持中的其中一個輪轂型刀片36的中央開口部38a。Next, the X-axis moving mechanism 12 and the Z-axis moving mechanism 10 are actuated to adjust the X-axis position and the Z-axis position of the blade holding portion 48 so that the shaft portion 34 of the blade supporting shaft 24 at the above-mentioned predetermined position can be inserted into the central opening portion 38a of one of the hub-type blades 36 attracted and held by the blade holding portion 48.

接著，藉由Y軸移動機構8使框體74在Y軸方向上移動，而將上述預定位置的刀片支撐軸24的軸部34***以刀片保持部48所吸引保持中的其中一個輪轂型刀片36的中央開口部38a，並且使其中一個輪轂型刀片36的端面接觸於刀片支撐軸24的基部32的端面。接著，解除刀片保持部48的吸引力，將所取下之一對輪轂型刀片36的其中一個交接到刀片支撐軸24。Next, the frame 74 is moved in the Y-axis direction by the Y-axis moving mechanism 8, and the shaft portion 34 of the blade support shaft 24 at the predetermined position is inserted into the central opening 38a of one of the hub-type blades 36 attracted and held by the blade holding portion 48, and the end surface of one of the hub-type blades 36 is brought into contact with the end surface of the base 32 of the blade support shaft 24. Next, the attraction of the blade holding portion 48 is released, and one of the removed pair of hub-type blades 36 is transferred to the blade support shaft 24.

又，藉由Y軸移動機構8使搬出入機構6從切削刀片保管機構4拉開間隔，並且使搬出入機構6的罩殼52旋轉180°，使吸引保持有已取下之一對輪轂型刀片36的另一個之相反側的刀片保持部48面對切削刀片保管機構4。In addition, the Y-axis moving mechanism 8 is used to separate the loading and unloading mechanism 6 from the cutting blade storage mechanism 4, and the cover 52 of the loading and unloading mechanism 6 is rotated 180° so that the blade holding portion 48 on the opposite side of the other of the pair of hub-type blades 36 that have been removed is attracted and held faces the cutting blade storage mechanism 4.

接著，藉由Y軸移動機構8使框體74在Y軸方向上移動，將上述預定位置之刀片支撐軸24的軸部34，***以相反側的刀片保持部48所吸引保持中的另一個輪轂型刀片36的中央開口部38a，並且使另一個輪轂型刀片36的端面接觸於被刀片支撐軸24支撐中的輪轂型刀片36的端面。接著，解除刀片保持部48的吸引力，將所取下之一對輪轂型刀片36的另一個交接到刀片支撐軸24。Next, the frame 74 is moved in the Y-axis direction by the Y-axis moving mechanism 8, and the shaft portion 34 of the blade support shaft 24 at the predetermined position is inserted into the central opening 38a of the other hub-type blade 36 attracted and held by the blade holding portion 48 on the opposite side, and the end surface of the other hub-type blade 36 is brought into contact with the end surface of the hub-type blade 36 supported by the blade support shaft 24. Next, the attraction of the blade holding portion 48 is released, and the other of the removed pair of hub-type blades 36 is transferred to the blade support shaft 24.

如此，在本實施形態之自動更換裝置2中，可以在之後裝設到已經交貨給使用者之切削裝置170，而對已裝設在切削裝置170的切削機構174之輪轂型刀片36進行更換。In this way, in the automatic replacement device 2 of the present embodiment, it is possible to later install it in the cutting device 170 that has been delivered to the user, and replace the hub-type blade 36 installed in the cutting mechanism 174 of the cutting device 170.

又，在自動更換裝置2中，不僅可更換輪轂型刀片36，也可更換墊圈型刀片45。在更換墊圈型刀片45時，是在未藉由刀片保持部48吸引保持更換用的新的墊圈型刀片45的狀態下，將搬出入機構6定位到切削裝置170的一對切削機構174之間。接著，使固定螺帽保持部50面對切削機構174，且藉由固定螺帽保持部50從切削機構174的主軸220取下固定螺帽222。In the automatic replacement device 2, not only the hub blade 36 but also the washer blade 45 can be replaced. When replacing the washer blade 45, the loading and unloading mechanism 6 is positioned between the pair of cutting mechanisms 174 of the cutting device 170 without the blade holding portion 48 sucking and holding the new washer blade 45 for replacement. Then, the fixing nut holding portion 50 is made to face the cutting mechanism 174, and the fixing nut 222 is removed from the spindle 220 of the cutting mechanism 174 by the fixing nut holding portion 50.

接著，使刀片保持部48面對切削機構174後，在刀片保持部48的第一吸引孔61生成吸引力來吸引保持裝設凸緣229，並且在第二吸引孔63生成吸引力，而以刀片保持部48來保持已裝設在主軸220之墊圈型刀片45，來將墊圈型刀片45以及裝設凸緣229吸引保持並從主軸220取下。Next, after the blade holding portion 48 is facing the cutting mechanism 174, an attraction force is generated in the first attraction hole 61 of the blade holding portion 48 to attract and hold the mounting flange 229, and an attraction force is generated in the second attraction hole 63, and the blade holding portion 48 is used to hold the washer-type blade 45 installed on the main shaft 220, so that the washer-type blade 45 and the mounting flange 229 are attracted, retained and removed from the main shaft 220.

接著，使搬出入機構6移動，使吸引保持有墊圈型刀片45以及裝設凸緣229之刀片保持部48和切削刀片保管機構4面對。又，使切削刀片保管機構4的無端軌道22旋轉，而將可支撐墊圈型刀片45之空的刀片支撐軸24定位到預定位置。Then, the carrying-in and carrying-out mechanism 6 is moved so that the blade holding portion 48 which attracts and holds the washer-type blade 45 and the mounting flange 229 faces the cutting blade storage mechanism 4. Again, the endless track 22 of the cutting blade storage mechanism 4 is rotated, and the empty blade support shaft 24 which can support the washer-type blade 45 is positioned at a predetermined position.

然後，讓墊圈型刀片45嵌合到空的刀片支撐軸24的軸部34，並且解除第二吸引孔63的吸引力，而將墊圈型刀片45交接至刀片支撐軸24。此時，第一吸引孔61的吸引力並未解除，由刀片保持部48進行之裝設凸緣229的吸引保持會繼續。Then, the washer-type blade 45 is fitted into the shaft portion 34 of the empty blade support shaft 24, and the attraction of the second suction hole 63 is released, and the washer-type blade 45 is transferred to the blade support shaft 24. At this time, the attraction of the first suction hole 61 is not released, and the attraction and retention of the mounting flange 229 by the blade holding portion 48 will continue.

接著，使切削刀片保管機構4的無端軌道22旋轉，而將支撐有應搬入切削裝置170之新的墊圈型刀片45的刀片支撐軸24定位到預定位置(例如刀片支撐軸24的軌道中的最下端的位置)。又，使搬出入機構6從切削刀片保管機構4遠離到不會妨礙讀取機構126的鏡子130位於上側作用位置之程度。Next, the endless track 22 of the cutting blade storage mechanism 4 is rotated to position the blade support shaft 24 supporting the new washer-type blade 45 to be carried into the cutting device 170 at a predetermined position (e.g., the lowest position in the track of the blade support shaft 24). Furthermore, the carrying mechanism 6 is moved away from the cutting blade storage mechanism 4 to a degree that does not hinder the mirror 130 of the reading mechanism 126 from being located at the upper working position.

接著，為了藉由讀取機構126來確認已定位在上述預定位置之墊圈型刀片45的種類，和應搬入切削裝置170之墊圈型刀片45的種類是否一致，所以藉由定位部134使升降台138上升，而將鏡子130定位到可藉相機128透過鏡子130來拍攝墊圈型刀片45之上側作用位置。Next, in order to confirm by the reading mechanism 126 whether the type of the gasket-type blade 45 positioned at the above-mentioned predetermined position is consistent with the type of the gasket-type blade 45 to be moved into the cutting device 170, the lifting platform 138 is raised by the positioning part 134, and the mirror 130 is positioned to the upper working position where the camera 128 can photograph the gasket-type blade 45 through the mirror 130.

此時，若鏡子130的反射面130a未朝向切削刀片保管機構4，即可藉由旋轉部132使鏡子130和旋轉工作台140一起旋轉，來讓鏡子130的反射面130a朝向切削刀片保管機構4。At this time, if the reflective surface 130 a of the mirror 130 is not facing the cutting insert storage mechanism 4 , the mirror 130 and the rotary table 140 can be rotated together by the rotating portion 132 to make the reflective surface 130 a of the mirror 130 face the cutting insert storage mechanism 4 .

接著，藉由相機128透過鏡子130的反射面130a來拍攝墊圈型刀片45的第一側面(朝向搬出入機構6側之面)。並且，藉由所拍攝到之墊圈型刀片45的第一側面的圖像，來讀取已施加於墊圈型刀片45的側面之表示種類的標示T(例如B005)。Next, the camera 128 photographs the first side surface (the side facing the loading and unloading mechanism 6) of the washer blade 45 through the reflective surface 130a of the mirror 130. And, the mark T (e.g., B005) indicating the type applied to the side surface of the washer blade 45 is read from the image of the first side surface of the washer blade 45 photographed.

然後，在從所讀取到之標示T讀取到之已定位在上述預定位置之墊圈型刀片45的種類，和應搬入切削裝置170之墊圈型刀片45的種類不一致的情況下，為了向操作人員通知該意旨，會使自動更換裝置2的警報(未圖示)、或自動更換裝置2的旋轉燈等的照明機構(未圖示)作動。Then, when the type of the washer-type blade 45 positioned at the above-mentioned predetermined position read from the read mark T is inconsistent with the type of the washer-type blade 45 to be moved into the cutting device 170, in order to notify the operator of this intention, the alarm of the automatic changing device 2 (not shown) or the lighting mechanism such as the rotating light of the automatic changing device 2 (not shown) will be activated.

另一方面，在已定位在上述預定位置之墊圈型刀片45的種類，和應搬入切削裝置170之墊圈型刀片45的種類是一致的情況下，會藉由定位部134使升降台138下降，而將鏡子130定位到不會有妨礙由搬出入機構6所進行之切削刀片的搬出/搬入之情形的下側退避位置。On the other hand, when the type of the washer-type blade 45 positioned at the above-mentioned predetermined position is consistent with the type of the washer-type blade 45 to be carried into the cutting device 170, the lifting platform 138 is lowered by the positioning portion 134, and the mirror 130 is positioned at the lower retreat position that will not hinder the carrying in/out of the cutting blade by the carrying-in and carrying-out mechanism 6.

接著，在吸引保持有裝設凸緣229之刀片保持部48的第二吸引孔63生成吸引力，且以刀片保持部48吸引保持更換用之新的墊圈型刀片45。亦即，藉由相同的刀片保持部48，來將更換用的新的墊圈型刀片45和裝設凸緣229一起吸引保持。Then, the second suction hole 63 of the blade holding portion 48 holding the installation flange 229 is attracted and generates an attraction force, and the blade holding portion 48 attracts and holds the new washer type blade 45 for replacement. That is, by the same blade holding portion 48, the new washer type blade 45 for replacement and the installation flange 229 are attracted and held together.

順道一提，在輪轂型刀片36中，因為設置有基台38以及切刃40，所以容易分辨正面、背面，在以下之情形上難以產生錯誤：讓輪轂型刀片36的正面、背面的方向一致來***切削刀片保管機構4的刀片支撐軸24(讓施加有標示T之側面朝向搬出入機構6來***)。By the way, in the hub-type blade 36, since a base 38 and a cutting edge 40 are provided, it is easy to distinguish the front and back sides, and it is difficult to make mistakes in the following situation: the front and back sides of the hub-type blade 36 are aligned when inserted into the blade support shaft 24 of the cutting blade storage mechanism 4 (let the side marked with T face the loading and unloading mechanism 6 for insertion).

另一方面，在墊圈型刀片45中，因為未設置有基台，而僅由切刃來構成，所以難以分辨正面、背面，而有在墊圈型刀片45的方向不一致的狀態下***刀片支撐軸24之情況。如此一來，會有墊圈型刀片45的施加有標示T之側面未朝向搬出入機構6之時，此時，會無法藉由讀取機構126在被切削刀片保管機構4保管中的狀態下讀取標示T。On the other hand, in the washer type blade 45, since there is no base provided and it is composed only of the cutting edge, it is difficult to distinguish the front and back sides, and there is a situation where the blade support shaft 24 is inserted in a state where the direction of the washer type blade 45 is inconsistent. In this way, there is a case where the side surface of the washer type blade 45 with the mark T applied is not facing the carrying-in and unloading mechanism 6. At this time, the mark T cannot be read by the reading mechanism 126 while the cut blade is stored in the cutting blade storage mechanism 4.

在如上述之時，會在藉由搬出入機構6的刀片保持部48將更換用之新的墊圈型刀片45和裝設凸緣229一起吸引保持，且已使搬出入機構6後退到框體74的內部之後，再藉由讀取機構126來讀取標示T。At the time as described above, the new washer-type blade 45 to be replaced and the mounting flange 229 are attracted and retained together by the blade holding portion 48 of the carry-in/out mechanism 6, and after the carry-in/out mechanism 6 has been retracted into the interior of the frame 74, the mark T is read by the reading mechanism 126.

也就是說，於使搬出入機構6後退後，藉由讀取機構126的定位部134使升降台138上升，並且藉由旋轉部132使旋轉工作台140旋轉180度。藉此，如圖22所示，將鏡子130定位在上側作用位置，並且讓鏡子130的反射面130a朝向已被刀片保持部48吸引保持之墊圈型刀片45。That is, after the carrying-in/out mechanism 6 is moved backward, the lifting platform 138 is raised by the positioning portion 134 of the reading mechanism 126, and the rotating table 140 is rotated 180 degrees by the rotating portion 132. Thereby, as shown in FIG. 22, the mirror 130 is positioned at the upper side action position, and the reflecting surface 130a of the mirror 130 is directed toward the washer-shaped blade 45 held by the blade holding portion 48.

接著，藉由相機128透過鏡子130的反射面130a來拍攝墊圈型刀片45的第二側面(和第一側面為相反側之側面)。然後，藉由所拍攝到之墊圈型刀片45的第二側面的圖像，來讀取已施加於墊圈型刀片45的側面之表示種類的標示T(例如B005)。Next, the second side surface (the side opposite to the first side surface) of the washer blade 45 is photographed by the camera 128 through the reflective surface 130a of the mirror 130. Then, the mark T (e.g., B005) indicating the type of the washer blade 45 applied to the side surface is read from the image of the second side surface of the washer blade 45 photographed.

然後，在從所讀取到之標示T讀取到之已定位在上述預定位置之墊圈型刀片45的種類，和應搬入切削裝置170之墊圈型刀片45的種類不一致的情況下，使警報等作動。Then, when the type of the washer-type blade 45 positioned at the above-mentioned predetermined position read from the read mark T is inconsistent with the type of the washer-type blade 45 to be moved into the cutting device 170, an alarm is activated.

另一方面，在已定位在上述預定位置之墊圈型刀片45的種類，和應搬入切削裝置170之墊圈型刀片45的種類是一致的情況下，會使搬出入機構6移動，使保持有裝設凸緣229以及新的墊圈型刀片45之刀片保持部48面對切削機構174。接著，將裝設凸緣229以及新的墊圈型刀片45交接至主軸220。然後，在使固定螺帽保持部50面對切削機構174之後，將固定螺帽222螺接於主軸220的公螺絲228。On the other hand, when the type of the washer blade 45 positioned at the predetermined position is consistent with the type of the washer blade 45 to be carried into the cutting device 170, the carrying-in/out mechanism 6 is moved so that the blade holding portion 48 holding the mounting flange 229 and the new washer blade 45 faces the cutting mechanism 174. Then, the mounting flange 229 and the new washer blade 45 are transferred to the main shaft 220. Then, after the fixing nut holding portion 50 faces the cutting mechanism 174, the fixing nut 222 is screwed to the male screw 228 of the main shaft 220.

如此，在本實施形態之自動更換裝置2中，可以在之後裝設到已經交貨給使用者之切削裝置170，而對已裝設在切削裝置170的切削機構174之墊圈型刀片45進行更換。In this way, in the automatic replacement device 2 of this embodiment, it can be installed in the cutting device 170 that has been delivered to the user, and the washer-type blade 45 installed in the cutting mechanism 174 of the cutting device 170 can be replaced.

如以上，在自動更換裝置2中，由於可以藉由讀取機構126讀取並確認要搬入切削裝置170之切削刀片的種類，因此可以確實地將已裝設在切削裝置170之切削刀片更換為期望的切削刀片。As described above, in the automatic replacement device 2, since the type of the cutting blade to be carried into the cutting device 170 can be read and confirmed by the reading mechanism 126, the cutting blade installed in the cutting device 170 can be replaced with the desired cutting blade reliably.

又，根據自動更換裝置2，即使是以正面、背面的方向不一致的狀態來將切削刀片(輪轂型刀片36或墊圈型刀片45)保管於切削刀片保管機構4的情況下，仍然可以藉由切削刀片的第一側面或第二側面的圖像，來讀取已施加於切削刀片的側面之表示種類的標示T。在上述的例子中，雖然是針對墊圈型刀片45來作說明，但針對輪轂型刀片36也是同樣。Furthermore, according to the automatic replacement device 2, even if the cutting blade (hub-type blade 36 or washer-type blade 45) is stored in the cutting blade storage mechanism 4 in a state where the front and back directions are inconsistent, the mark T indicating the type applied to the side of the cutting blade can still be read by the image of the first side or the second side of the cutting blade. In the above example, although the description is made for the washer-type blade 45, the same is true for the hub-type blade 36.
