Conventionally known transfer feeders are equipped with transfer feed devices incorporating rotating cams on the left and right sides (or front and back) of the press, which are connected via shafts, miter gears, coupling rings, etc., and are driven by motors and decelerations. This is done by a camshaft driven via a motor, transmission, etc., and the rotations of the respective rotary cams are synchronized. In such a transfer feed device, due to the characteristics of the rotating cam, the upstroke and downstroke of the rotating cam are repeated, so that during one stroke, the follower drives the rotating cam. At this time, the camshaft momentarily increases speed by the amount of the total backlash in the drive gear, and when the backlash disappears, the rotating cam rotates at a constant speed. Furthermore, when the driving force from the follower is removed, the rotating cam stops for a moment, and then starts rotating at a constant speed again.
This repetition of constant speed - speed increase - stop - constant speed causes pulsations in the follower side and the camshaft drive system.

この脈動は機械の寿命低下、振動、騒音という

As shown in FIG. 2, a rotating cam 4 and a camshaft 5,
6 is rotating in the direction of the arrow N, the force that the cam 4 receives from the roller 19 during the downward stroke of the rotating cam 4 is P 1 , and the torque applied to the cam shafts 5 and 6 in the direction of the arrow (clockwise)
A rotational force of T 1 is generated. Next, when the rotating cam 4 rotates by θ, the rotating cam 4 changes to an upward stroke.
The force that the rotating cam 4 receives from the roller 19 at this time is
P 2 generates a torque T 2 in the direction of the arrow (counterclockwise) on the camshaft. This torque T 1 ,
A graph of T 2 in a conventional device without a brake is shown in Figure 3. If T 2 is positive, then T 1
is negative. T 1 acts to change the direction of variation in the camshaft system and drive system.

Therefore, when looking at the rotational speed of the rotary cam during one rotation of the cam, the phenomenon of "constant speed - speed increase - stop - constant speed" is repeated. This is for one rotating cam,
As the number of rotating cams increases, the above phenomenon becomes even more significant.

A graph of the torque of the camshaft when brakes 15a and 15b B are provided is shown in FIG. Since the torque T 1 <T B , the camshaft driving torque is always in the positive direction, and therefore the rotating cam 4 has a constant rotation speed.

As described above, according to this invention, a brake is attached to the camshaft with a torque capacity larger than the negative torque value generated by the repeated up stroke and down stroke of the rotating cam, and the driving force from the motor is always kept constant. Since the load is applied in one direction, any backlash on the drive system is eliminated in one direction, resulting in smooth rotation at a constant speed. Also, on the slave side, it is possible to obtain smooth movement along the locus of the rotating cam that rotates at a constant speed, thereby reliably eliminating problems such as pulsation, vibration, and noise in various parts, and withstanding high-speed operation. A long-life transfeed device can be obtained.
