Automatic position controlling apparatus

An automatic position controlling apparatus of a playback system, comprising

• means for teaching positional data of a plurality of points,
• driving means responsive to said positional data of said plurality of points, as taught, for driving an apparatus to be position controlled, smoothing means acting on said driving means, said smoothing means including
• means for evaluating a formula of a curve smoothly connecting said taught positional data of a plurality of points associated with each other,
• means responsive to said evaluated curve formula for evaluating a commanded position for every predetermined time interval less than the response time period of said driving means,
• means for correcting said commanded position according to a time delay in the response characteristic of said driving means,
• detecting means for detecting whether the next successive taught points is a point previously specified for disenabling said smoothing means, and
• disenabling means responsive to said detection means for disenabling said smoothing means when one of said previously specified points is detected.

• wherein said automatic position-controlling apparatus is formed as a working apparatus, said working apparatus being adapted to, by means of said apparatus being controlled, work a press formed workpiece, and which further comprises
• means for positioning said press formed workpiece,
• said workpiece positioning means comprising a mold for said workpiece being press formed obtained by pouring a time dependent settable material into said workpiece as press formed and by dipping a portion of a reinforcing member in said poured material, whereupon said reinforcing member as exposed from said material is adapted to be mounted on a predetermined position of supporting base.

• means for teaching positional data of a plurality of points,
• driving means responsive to said positional data of said plurality of points, as taught, for driving means to be position controlled,
• means for evaluating a formula of a curve smoothly connecting said plurality of position points, as taught, associated with each other,
• means responsive to said evaluated curve formula for evaluating a commanded position for every predetermined time interval smaller than the response time period of said driving means,
• means for correcting said evaluated commanded position in consideration of a time delay in the response characteristic of said driving means,
• a base,
• an arm carried at one end by said base to be movable in the left/right direction,
• a moving member carried by said arm to be movable in the forward/rearward direction,
• a column carried by said moving member to be movable in the upward/rearward direction and for supporting said apparatus being controlled,
• a spring balancer fixed to one end of said arm,
• first and second pulleys separately supported by said moving member by means of a left-right directional axis,
• a third pulley supported by said column by means of a left/right directional axis, and
• an extension of said balancer being fixed at the tip end thereof to the other end of said arm while the same is entrained midway around said first, third and second pulleys in the order described, a taking up force of said extension of said balancer being approximately a half of the total weight of said column and the components carried by said column.
