 従来、ガラス板の端面の研削作業において、研削ホイールのドレッシング作業は、別工程として行われていた。即ち、ドレッシング作業は、研削作業を一時中断したうえで、研削ホイールの研削面にスティック状のドレッサをエアシリンダ装置又は作業者の手作業により行われている。 Conventionally, in the grinding work of the end face of the glass plate, the dressing work of the grinding wheel has been performed as a separate process. That is, the dressing operation is performed by temporarily suspending the grinding operation and then applying a stick-shaped dresser to the grinding surface of the grinding wheel by an air cylinder device or an operator's manual operation.
 また、ドレッシング作業を作業者の手作業によらず、ドレッサを保持したエアシリンダ装置等からなるドレッシング装置であっても、研削ヘッドが移動して、ガラス板の周囲を研削するところのガラス板の研削装置等においては、ドレッシング装置は研削ヘッドから分離され、別体として、研削ヘッドの復帰位置等に配置されている。 Even if the dressing device is a dressing device composed of an air cylinder device or the like that holds a dresser, regardless of the manual operation of the operator, the grinding head moves to grind the periphery of the glass plate. In a grinding apparatus or the like, the dressing apparatus is separated from the grinding head, and is disposed as a separate body at a return position or the like of the grinding head.
 研削ヘッドが研削作業の移動から原点等に復帰し、停止したとき、余分の時間を執ってドレッシング作業を行っている。 When the grinding head returns to the origin from the movement of the grinding work and stops, the dressing work is performed with extra time.

 上述のように、従来のドレッシング作業は、研削作業とは別工程において行われているため、研削作業を一時中断して行われなければならないため、中断分の時間がロスし、全体として研削作業の能率が悪くなっている。 As described above, since the conventional dressing work is performed in a separate process from the grinding work, the grinding work must be suspended temporarily, so the time for the interruption is lost and the grinding work as a whole is performed. The efficiency of is getting worse.
 また、作業者の手作業によるドレッシング作業は安全面から問題がある。 Also, manual dressing work by workers is problematic from the safety aspect.
 更に、研削ヘッドが移動して研削作業を行う研削装置にあっては、研削ヘッドが原点等に復帰、停止してのドレッシング作業にあっては、ドレッシング装置の動作のうえにドレッシング作業時間を要し、ロス時間となり、全体としての研削作業、能率が悪い。 Furthermore, in a grinding device that moves the grinding head and performs the grinding work, in the dressing work in which the grinding head returns to the origin or the like and stops, a dressing work time is required in addition to the operation of the dressing device. However, the time is lost, and the overall grinding work and efficiency are poor.

 研削装置1によると、研削ヘッド2自体にドレッサを保持したドレッシング装置40を設け、ドレッシング装置40は、研削ホイール3において、ガラス板5の研削を行う研削作業点Aの反対側Bに設けられ、かつドレッシング装置40はON・OFFの指令信号に基づいて、研削ホイール3の研削面4に対してドレッサ41の押し付け及び離間を行うようになっているため、研削ヘッド2がガラス板5の研削作業中、研削作業を行わない移動中、停止中等のいずれの状態を問わず(に関係なく)、いつでも研削ホイール3の研削面4のドレッシング作業を進行させることができ、また、ドレッシング作業の中断、停止もできる。 According to the grinding device 1, the dressing device 40 holding the dresser is provided on the grinding head 2 itself, and the dressing device 40 is provided on the grinding wheel 3 on the opposite side B of the grinding work point A for grinding the glass plate 5, In addition, the dressing device 40 presses and separates the dresser 41 from the grinding surface 4 of the grinding wheel 3 based on the ON / OFF command signal, so that the grinding head 2 performs the grinding work of the glass plate 5. The dressing operation of the grinding surface 4 of the grinding wheel 3 can be carried out at any time regardless of (whether or not) the state where the grinding operation is being performed, the movement is stopped, and the like. You can also stop.
 即ち、例えば、研削ホイール3の前部においてガラス板5の研削作業を進めながら、後方において、研削ホイール3の研削面4のドレッシング作業を並行して進めることができるため、ガラス板5の研削作業とドレッシング作業とを同時に共存状態におくことができる。一連の研削工程において必ず存在する研削ヘッド2の研削作業の途切れ時間中、研削ヘッド2の空移動中、停止中においても、自由にドレッシング作業が行えるため、別工程のドレッシング作業は不要となる。 That is, for example, since the dressing operation of the grinding surface 4 of the grinding wheel 3 can be performed in parallel while the grinding operation of the glass plate 5 is proceeding at the front portion of the grinding wheel 3, the grinding operation of the glass plate 5 is performed. And dressing work can coexist at the same time. Since the dressing operation can be performed freely during the interruption time of the grinding operation of the grinding head 2 that is always present in a series of grinding processes, even when the grinding head 2 is idle and stopped, a separate dressing operation is not required.
 よって、研削作業を中断、その他の動作時間の延長等のロス時間がなくなり、研削効率が高くなる。また、ドレッシング作業の続行時間の調整、開始、中断のタイミングが、研削作業中、研削ヘッド2の移動中等にかかわらず、自由に、かつ、適切に行い得るため、常に研削面4がリフレッシュされ得、また、ドレッサ41の無駄な消耗を避けることができる。 Therefore, the grinding work is interrupted and other lost time such as extending the operating time is eliminated, and the grinding efficiency is increased. Further, since the timing for adjusting, starting and interrupting the continuation time of the dressing operation can be performed freely and appropriately regardless of whether the grinding head 2 is moving or the like, the grinding surface 4 can always be refreshed. Moreover, useless consumption of the dresser 41 can be avoided.
