摘要： A conveyer for transporting a box and a conveyer for transporting a bottle are driven along a follow-up target axis and a follow-up axis, respectively. The follow-up axis is accelerated from a synchronization start position, and, when the follow-up axis velocity catches up with the conveyer, performs the constant velocity operation. An advanced operation, performed by an asynchronous axis (moving the bottle closer to the box), is started before synchronization completes, and is completed when synchronization completes, then immediately an operation by a synchronous axis (follow-up target axis or follow-up axis) is started (insertion operation). The point of time when the advanced operation is started is determined by processing of the numerical controller, as a point of time when the time required for the follow-up axis in the current status to reach the synchronization completion status becomes the same as the time required for the advanced operation (preset).

摘要： A die cushion controller uses position control to position die cushion members for placement of a metal sheet. A pressing process starts and the upper die is lowered. When a position detector detects a position at which the upper die touches the sheet metal, the die cushion controller switches over from position control to pressure control and applies a preset pressure to the sheet metal. When the position detector detects that the upper die has risen to a preset position, the die cushion controller clears the positional deviation accumulated in position control to zero, then moves the die cushion members to preset positions and holds them there.

摘要： Die cushion control device that implements die cushion control while making a switch between position control and pressure control by using servomotors, and reduces the impact caused by a collision between a press axis and a die cushion axis during position control. Die cushion members are controlled by servomotors Md. The changeover switch is connected to the “a”-side, to thereby control the position (velocity) of the servomotors Md by commands from a numerical controller and control the position of the die cushion members. During position control, the output torque of the servomotors Md is limited by torque limit means. During position control, even if the press axis hits the die cushion members due to erroneous setting, wrong operation or the like, the servomotors Md merely output only a limited torque or less, so that impact force is reduced, which prevents damage to the die cushion members and the press axis. During press operation, when a position detector detects that the press axis moves downward to reach a predetermined position, the changeover switch is connected to the “b”-side, to thereby implement pressure control.
摘要翻译：模具缓冲控制装置，通过使用伺服电动机进行位置控制和压力控制之间的切换，实现模具缓冲控制，并且减少在位置控制期间由冲压轴和模具缓冲轴之间的碰撞引起的冲击。模具缓冲构件由伺服电机Md控制，转换开关连接到“a”侧，从而通过来自数字控制器的命令来控制伺服电机Md的位置（速度），并控制模具缓冲构件的位置。在位置控制期间，伺服电动机Md的输出转矩由转矩限制装置限制。在位置控制期间，即使由于错误的设定，错误的操作等而使按压轴碰到模具缓冲部件，伺服电动机Md只输出有限的转矩或更小的扭矩，从而减小冲击力，从而防止对模具的损坏缓冲构件和压轴。在按压操作期间，当位置检测器检测到按压轴向下移动到达预定位置时，转换开关连接到“b”侧，从而实现压力控制。

摘要： A servomotor in a numerical controller is controlled by automatically switching to either pressure control or position control in association with the command which is smaller from among a command obtained by performing pressure feedback control and a command obtained by performing position feedback control. When switched to pressure control while moving according to a movement command, the output of the movement command is terminated halfway, and the command in the next block is executed, and pressure control of the next command is immediately started. As a result, a wasteful time is eliminated, and a cycle time of the operation can be shortened.

摘要： Disclosed is a numerical controller capable of foreseeing the occurrence of interference during operation of a machine and securely preventing the interference. An advanced position calculating section determines advanced time for the next interference check, based on an end time point of an interference check by an interference checking device and the sum of a time required for the interference check, a time required for communication, a time required for decelerating and stopping a movable part, and a predetermined float. Further, an advanced position of the movable part at the advanced time is calculated based on pre-read program data and is outputted to the interference checking device. The interference checking device performs the interference check at the advanced position. If it detects interference, the interference checking device delivers an axis stop signal to a motion command output section, thereby stopping a motion command and decelerating and stopping the movable part. Since interference check timing is settled in accordance with the time required for the interference check, the occurrence of interference can be securely prevented without delay or advance.

摘要： Initial speeds in the move commands for respective control axes at servo-on are determined according to parameter setting, or the comparative relationship or difference in speed among the actual speeds of the control axes so that difference in position between the control axes does not increase as the move commands are executed after the servo-on. The actual speeds of the control axes are set as initial speeds in the move commands, and a target axis is specified on the basis of the comparative relationship among their actual speeds and the other control axes are accelerated or decelerated at the acceleration or deceleration rate specified in the move commands to attain the position and speed of the target axis, so that differences in position and speed among the control axes are gradually decreased as the move commands are executed after the servo-on, thereby preventing abrupt speed changes and suppressing mechanical shocks.

摘要： A synchronous controller capable of gently changing a synchronous multiplying factor and setting the gentleness of changing of the synchronous multiplying factor without shocking a machine. A block for gently changing the synchronous multiplying factor is added between blocks before and after the changing of the synchronous multiplying factor. Synchronous multiplying factors a and b before and after changing of the synchronous multiplying factor designated in the added block, a motion amount p of master axis, a motion amount of a slave axis, and a residual motion amount v of the master axis after the completion of changing the synchronous multiplying factor (or a preliminary motion amount u of the master axis from the start of motion of the block concerned to a position for the start of changing of the synchronous multiplying factor) are read out. A gradient of changing the synchronous multiplying factor and the preliminary motion amount u (or the residual motion amount v) are obtained based on these data. The slave axis is controlled based on the motion amounts u and v and the gradient of changing the synchronous multiplying factor. The synchronous multiplying factor is changed so gently that the machine cannot be shocked. The synchronous multiplying factor gradient can be settled depending on the designated data p, q and v (or u).
