Abstract

PURPOSE:To provide a drive system using servo motor which can adapt to various working processes and work well for different processes by supporting an eccentric can on the rotary shaft of the servo motor in cantilever form, and permitting a slider detained with the cam with slidability to make composite motions through combination of the regular and reverse directions and the high and low speeds. CONSTITUTION:Through a bearing, an eccentric cab 7 is supported on the rotary shaft 11a of a servo motor 11 in a cantilever form. A transmitting roller 8 is installed on the cam 7 and detained slidably with a U-form slider 9, which is placed on a guide 10 slidably so that a drive system unit is formed. When the servo motor 11 is rotated, the roller 8 makes cyclic motions following a locus of sine curve, and the slider 9 makes reciprocation on the guide 10. The reciprocation is taken out from the slider 9, and works of any process are executed. By the drive control software of the servo motor 11, the slider 9 can be put in composite motions through combination of the regular and reverse directions and the high and low speeds.

2. Description of the Related Art Generally, a ball screw is used to obtain a reciprocating motion using a servomotor, and a coupling for connection (universal joint, flexible wire joint, etc.) is used to deflect the power output direction. There are limits to high-speed driving, and high-speed driving cannot be expected. Further, when the timing belt, the ball screw and the like are used by holding both of them, a large occupying area is required depending on those members, and it is not suitable for being incorporated in a complicated device. In addition, a system that obtains mechanical reciprocating motion (such as a cam) can achieve high speed, but the number of parts increases,
A lot of time is required for assembly and adjustment. There has been a great demand for a simple way to obtain high speed reciprocating motion.

[Means for Solving the Problems] As described above, it is difficult to mount the timing belt and the ball screw having both ends in a complicated place by the conventional technique. In order to achieve this, a cantilevered eccentric cam is provided on the rotary shaft of the servomotor, and when the eccentric cam rotates, the transmission roller also makes a circular motion such as a sine curve to cycle. A servo motor, an eccentric cam, a transmission roller, and a U-shaped slider are configured by engaging a U-shaped slider that can slide left and right with the transmission roller and directly converting the circular motion into reciprocating motion. As a means of solving the problem. In addition, by combining the start and stop of the servomotor with the rising and falling curves of the circular motion, a smoother rising and falling curve can be obtained.
Higher speed reciprocating motion is possible. Then, as a drive system unit that configures them, one unit or a plurality of units are installed in a complicated place and each servo motor is moved forward or backward or reciprocally with an arbitrary drive amount according to the timing of drive control software. It is possible to perform multiple steps of work at high speed by obtaining a combined operation of high speed and low speed.

When the servo motor 11 rotates, the transmission roller 8 of the eccentric cam 7 cycles along a locus of a sine curve. Since the transmission roller 8 is slidably engaged with the U-shaped slider 9, the movement of the transmission roller 8 of the eccentric cam causes the U-shaped slider 9 to reciprocate left and right on the guide 10 as indicated by the arrow. . This left-right reciprocating motion is taken out from the U-shaped slider 9, and the work of an arbitrary process is performed. Since the eccentric cam 7 is connected to the rotary shaft 11a of the servomotor 11 in a cantilever manner, the structure can be made compact as compared with the conventional device.
