2results about How to "Avoid mechanical collision" patented technology

The application provides a multi-leaf collimator assembly, a radiotherapy device and a leaf locking method. The multi-leaf collimator assembly comprises a frame and at least two spaced-apart leaf collimators; each leaf collimator is slidably connected to the frame and can slide in a first direction; the assembly further comprises a driving device and a locking member connected to the driving device; when the leaf collimator slides into an initial position in the frame, the driving device can drive the locking member to abut against the leaf collimator in a second direction, and the leaf collimator abuts against the frame; the first direction and the second direction are both perpendicular to the thickness direction of the leaf collimator, and the first direction and the second direction are not parallel. The driving device can drive the locking member to abut against the leaf collimator, so that the leaf collimator abuts against the frame, thereby fixing the leaf collimator by using the friction between the leaf collimator and the frame and the friction between the leaf collimator and the locking member, and thereby avoiding mechanical collision of the leaf collimator or weakening the mechanical collision intensity during the acceleration and deceleration stages of high-speed rotation of the multi-leaf collimator assembly.

This utility model discloses a PLC-controlled flipping mechanism for an FDY automated packaging line, including a flipping frame, a rotating arm, a cylinder, a reducer, a photoelectric sensor, and a PLC controller. The mechanism achieves 180° flipping of the silk cake through synchronous lifting of the cylinder and driving of the rotating arm by the reducer. With the help of photoelectric sensors and limit switches to detect the position, it solves the problem of the orientation of the tail silk during palletizing. The structure is compact, and it can be seamlessly integrated into existing production lines in a single flip, significantly improving the efficiency of automated packaging.
