In the conventional technique, as shown by the line L2 in Fig. 3, the timing of the start of the rise of 1 is slow, so it is necessary to rise at a high speed. According to the present invention, "from the end of the lock to the end of the rise" Design: It is longer than the conventional technology, so When the module is operated in the same cycle time, the second and the second can be moved to the most, and the slower and slower. i sets the maximum ascent speed to be higher than the conventional technique. Therefore, according to the present invention, even if the cycle time is shortened to The conventional technology 319753 13 200902301 can also be used to drive the mold buffer 11 (such as the oil or empty ink machine, in this embodiment, the cylinder drive source 17). The power is reduced to reduce the amount of energy consumption. Secondly, the height of the workpiece handling device 21 on the exit side is constantly monitored, and as shown by the line L3 of the brother 4, the nightmare is controlled! s 4 μ — the dream dream 9...: The driving of the lifting/lowering mechanism 15 is controlled such that the southward degree of the workpiece-moving wave on the outlet-side is changed to change the degree of increase of the mold buffer η by a constant k degree, and the operation of the workpiece-feeding device 21 on the outlet side is correctly followed by the nozzle In this case, the advancement speed of the mold buffer u is slowed down. Further, when the distance between the upper surface of the mold buffer u and the outlet side::: holding portion 22 becomes a predetermined value or less =
