AI Technical Summary
【0012】 本発明の自動交換装置は、 被加工物を保持する保持面を備えたチャックテーブルと、該チャックテーブルに保持された被加工物を切削する切削ブレードを固定ナットで装着した切削手段と、該チャックテーブルをX軸方向に加工送りするX軸送り手段と、該切削手段をX軸方向と直交するY軸方向に割り出し送りするY軸送り手段と、X軸方向およびY軸方向と直交するZ軸方向に該切削手段を切り込み送りするZ軸送り手段とを備え、該保持面がX軸方向およびY軸方向で規定された切削装置に連結可能な自動交換装置であって、 複数の切削ブレードを保管する切削ブレード保管手段と、該切削ブレード保管手段から搬出した切削ブレードを該切削手段まで搬送するとともに該切削手段から離脱した切削ブレードを搬入する搬出入手段と、制御手段と、切削装置まで移動するための移動手段と、を含み、該制御手段は、複数の切削装置から送信される信号を受信する受信部と、複数の切削装置の場所を記録する場所記録部と、該受信部が受信した信号と該場所記録部とを照合して自動交換装置が移動すべき切削装置の場所を特定する場所特定部と、該場所特定部が特定した場所に基づいて該移動手段を作動する作動部と、を備え、 該移動手段は、特定された場所まで移動する移動部と、切削装置側の被連結部と連結することで、自動交換装置と切削装置との位置決めとして機能する連結部と、を備えているので、一台の自動交換装置によって複数の切削装置に対して切削ブレードの交換が可能であり、自動交換装置の稼働率を向上することができる。

Abstract
Claims
[Claim 1] An automatic exchange device comprising a chuck table having a holding surface for holding a workpiece, a cutting means having a cutting blade for cutting the workpiece held on the chuck table attached with a fixing nut, an X-axis feed means for feeding the chuck table in the X-axis direction, a Y-axis feed means for indexing and feeding the cutting means in the Y-axis direction perpendicular to the X-axis direction, and a Z-axis feed means for cutting and feeding the cutting means in the Z-axis direction perpendicular to the X-axis and Y-axis directions, wherein the holding surface is connectable to a cutting device defined in the X-axis and Y-axis directions, An automatic exchange device comprising: a cutting blade storage means for storing multiple cutting blades; an loading / unloading means for transporting cutting blades loaded from the cutting blade storage means to the cutting device and loading cutting blades detached from the cutting device; a control means; and a moving means for moving to a cutting device, wherein the control means comprises a receiving unit for receiving signals transmitted from multiple cutting devices; a location recording unit for recording the locations of multiple cutting devices; a location identification unit for identifying the location of a cutting device to which the automatic exchange device should move by comparing the signals received by the receiving unit with the location recording unit; and an operating unit for operating the moving means based on the location identified by the location identification unit, wherein the moving means comprises a moving unit for moving to the identified location and a connecting unit for connecting to a connected part on the cutting device side, thereby functioning as a positioning device between the automatic exchange device and the cutting device. [Claim 2] The automatic blade exchange device according to claim 1, comprising: a blade recognition unit that recognizes the type of cutting blade requested by a signal transmitted from a cutting device to which the automatic blade exchange device is to move; and a selection unit that selects the type of cutting blade recognized by the blade recognition unit from the cutting blade storage means. [Claim 3] The system comprises: a Y-axis moving means for positioning the loading / unloading means in an operating position and a retracted position in the Y-axis direction relative to the cutting blade storage means; a Z-axis moving means for moving the loading / unloading means in the Z-axis direction; and an X-axis moving means for moving the loading / unloading means in the X-axis direction to position it in an operating position that acts on the cutting blade mounted on the spindle of the cutting means. The automatic replacement device according to claim 1, wherein the loading and unloading means includes a Z rotation axis extending in the Z axis direction, a blade holding part radially connected to the Z rotation axis and holding the cutting blade by suction, and a fixing nut holding part that screws the fixing nut onto and off a male thread formed at the tip of the spindle. [Claim 4] The automatic exchange device according to claim 3, wherein the loading and unloading means is disposed on a frame via a bent arm of the X-axis moving means, the frame is slidably supported on a guide rail extending in the Y-axis direction disposed on a lifting table, and the Y-axis moving means positions the cutting blade storage means to the working position and the retracted position in the Y-axis direction.
