Weaving shed forming device for shuttle loom, has autonomous assembly comprising support placed at proximity of motor block, electric circuit mounted on support, where support comprises cooling pipes for discharging coolant

摘要

#CMT# #/CMT# The device has an autonomous assembly (E) operating a drawing assembly and comprising electric motor block (40A) e.g. brushless synchronous motor blocks. An annular joint (80A) is made of elastic material. The drawing assembly is formed of distal connecting rods, oscillating levers, proximal connecting rods and pivots. An electric circuit (54A) transmits electric power to the block. The assembly (E) has a support (51) placed at the proximity of the block. The circuit is mounted on the support. The support has cooling pipes (51D, 51E) discharging coolant e.g. water. #CMT#USE : #/CMT# Device for forming a weaving shed for a shuttle loom (claimed). #CMT#ADVANTAGE : #/CMT# The device permits cooling of the motor blocks and the electric circuits using common cooling circuit, thus reducing hardware cost and installation cost of the shuttle loom. The arrangement of the device avoids the need to individually connect electric circuits associated to different actuators to power sources and communication circuits, thus reducing number of electrical cables, and hence reducing cost of the device. The weaving shed forming device is compact, and limits electromagnetic disturbances, thus reducing risk of failures. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of an autonomous assembly of a weaving shed forming device.
