摘要:
An electric shedding machine (1) of a loom includes heald frames (2), motors (3) driving the heald frames (2), a setting device (5), a storage device (7), a calculating device (8), and a controlling device (6). The setting device (5) sets a weaving condition including factors including a weaving pattern, rotational speed of the loom, weft type, weft density, and textile width. The storage device (7) stores a shedding motion condition database including weaving conditions and shedding motion conditions, which include a dwell period and a dwell phase and is related to the weaving conditions, to drive the heald frames (2). The calculating device (8), on the basis of the set weaving condition and the shedding motion condition database, immediately extracts the shedding motion condition corresponding to the set weaving condition when such corresponding shedding motion condition exists or performs interpolation calculation of a shedding motion condition corresponding to the set weaving condition from a weaving condition related to the set weaving condition when such corresponding shedding motion condition does not exist. The controlling device (6) controls rotations of the motors (3) on the basis of the extracted or interpolated shedding motion condition.

This shedding device in a weaving machine comprises one or more motor groups including a plurality of motors (40) provided in every heald frame (16) and directing their output shafts (42) in the forward and backward direction of the weaving machine. The motors (40) of each motor groups are arranged in the upward and downward, rightward and leftward directions, and two or more motors (40) operating as at least part of the motor group are arranged in the longitudinal direction of a connecting member (46) connecting the motors (40) with support mechanisms (20) of the heald frames (16) to form one or more motor rows opposing to one or more connecting members (46), and adjoining motors (40) in the motor row or rows are related to non-adjoining heald frames among the heald frames (16) corresponding to the support mechanisms.

摘要:
The present invention relates to an apparatus for driving a heald frame of a loom, and particularly, it is an object of the present invention to provide an apparatus for driving a loom heald frame using a linear motor having a sufficiently large driving force and being capable of securing a sufficiently long driving stroke. A heald frame 21 is driven vertically along a guide 23 by the driving force of a linear motor 24 transferred through a connecting lever 26. At this moment, by utilizing the principle of a lever and fulcrum, using a connecting lever 26 and the fulcrum 26a, a large driving force is obtained by using a linear motor with a long stroke, or a long stroke necessary to drive the heald frame is obtained by using a linear motor with a large driving force. By adopting such a configuration, the heald frame 21 can be vertically driven by a sufficiently large driving force and a sufficiently long stroke.

The thread processing device (8) of a textile machine has at least one thread guiding device that moves a thread (4) back and forth between at least two positions (12, 14) by means of a thread guiding member (30, 32, 34). The thread guiding member may be moved in one direction by means of an interlocking drive (28) and in the opposite direction by a frictional engagement drive (36) that acts against the interlocking drive (28). The textile machine is substantially improved by designing the frictional engagement drive (36) as a pneumatic drive with an individual gas chamber (64) that contains a gas volume that may be compressed by the interlocking drive at the working frequency. The gas chamber communicates with a compressed gas source through a non-return valve.

Die Anordnung umfasst Webschäfte (1), Linearantriebe (2) und Kupplungsmittel (3), die in Gruppen zusammengefasst sind. Die Linearantriebe jeder Gruppe sind gestaffelt angeordnet und bilden eine Antriebseinheit. Die Kupplungsmittel sind so ausgestaltet, dass die Staffelung innerhalb der Gruppe wählbar ist. Mit dieser Anordnung wird ein optimales Verhältnis von Antriebsleistung zu Raumbedarf und eine Standardisierung der eine Gruppe bildenden Elemente erreicht.
摘要:
In a weave machine of negative type, the heald frames are controlled by means of a linkage comprising: a rigid bar controlled by said machine; a plurality of angle levers which are pivoted to the loom frame, are hinged to said bar and are connected by connecting rods to the heald frame; and spring return means acting on said rigid bar.
