Abstract

PURPOSE:To stably control a moving unit, by losing the weight of the moving unit moving in the vertical or slanting direction, with the tensile force of a spring plate. CONSTITUTION:A stator frame is fitted on a motor fixed way, and a mover frame is butted to the open end section. A guide rod is penetrated into the sleeve bearing of the mover frame, and the mover frame interior is provided with a mover. Then, by conducting stator windings electrically, the mover is vertically and linearly moved in parallel with a stator. Then, at the lower end of the mover, a constant-tension spring unit 9 for losing the weight of the mover is fitted. The unit 9 is composed of a bobbin 13 supported rotatably by a unit frame 10 fixed on the lower end face of the mover, a spring plate 14 lap-wound on the bobbin, and position detecting means 18, 19 for detecting the elongation (return) of the spring plate. Then, the return force of the pulled- out spring plate 14 is equal to the gravity with addition of the weight of the mover, and by the position detecting means 18, 19, the position and the moving speed can be transmitted to the controlling section side.

2. Description of the Related Art Conventionally, a linear motor has been used as a driving device for moving a movable body linearly parallel to a fixed body. This linear motor exhibits its characteristics when the mover moves in the horizontal direction with respect to the stator. However, when operating in the vertical direction or in an area with a predetermined inclination angle, the weight of the slider affects the characteristics of the linear motor, so the accuracy of acceleration, deceleration, speed maintenance, stopping, etc. is determined by the i-control unit's commands. There will be variations in the value, resulting in an unstable state. This is because the gravity of the slider acts negatively on the thrust of the linear motor when the slider moves upwards, and positively when it moves downwards, so it is controlled according to commands from the control unit. Because you can't. In particular, in the case of a near-pulse motor that moves by a predetermined number of steps in response to an input pulse signal, the control command and the pulse position are likely to deviate due to the gravity of the mover, and this deviation causes the problem of step-out.

From the above, in order to increase the thrust of the linear motor and reduce the influence of the weight of the mover, conventional methods have been to increase the thrust by arranging the stator windings so as to straddle both sides of one mover. We are trying to However, this structure not only requires a complicated slider guide mechanism to keep the gap plane between the stator teeth and the slider constant on both sides of the slider, but also requires two stator windings. It is expensive because it requires a base.

On the other hand, efforts have been made to increase the thrust force with a single stator by increasing the size of the stator windings, but the mover also becomes larger and weighs more, making it difficult to move vertically or inclinedly, or to use a near motor. This is not an effective thrust increase. Furthermore, in a near motor in which the movable element operates vertically or in an inclined direction, in addition to the above-mentioned controllability problems, a phenomenon occurs in which the movable element is lowered by the weight Q of the movable element when the power supply of the motor is turned OFF. Due to this effect, when the power is turned off, the memory position of the I11 section and the position of the controlled section are different, so it may be necessary to align the two when the power is turned on next time, or the mover may be damaged. is inviting. Furthermore, position detectors that detect a moving element that moves in parallel are generally more expensive than other detectors such as rotary detectors.
