時に昇降キヤレツジ８に非常停止が掛けられる。 The elevating carriage 8 stops at the position corresponding to the highest detected plate 25 and the lowest detected plate 25 under the above control, and is not allowed to move upward or downward beyond these highest and lowest positions. However, when the elevating carriage 8 descends beyond the position corresponding to the lowest detection plate 25 due to a failure in the control system, etc., the carriage 8 falls to a position near the lower end of the post 6 as shown in FIG. Detector 1 for lowering high speed cutting by attached attachment 24
8 and the emergency stop detector 17 are activated in this order. First, the descending high-speed cutting detector 18 is activated to automatically switch the descending speed of the lifting carriage 8 to a low speed even if it is high. Due to the activation of the emergency stop detector 17, the motor 1
At the same time as the carriage 5 is stopped, the brake is activated and the elevating carriage 8 is brought to an emergency stop. Furthermore, when the lifting carriage 8 rises beyond the position corresponding to the highest detected plate 25, the attachment 23 causes the rising high-speed cut detector 16 and the emergency stop detector 17 to operate in this order. An emergency stop is applied to the elevating carriage 8 at the same time as the emergency stop action during descent.
