Description

The invention relates to the field of textile engineering and relates to the design of a hoop carriage to a weaving machine.

A known hooped carriage to a weaving machine, which includes heald frames connected by a system of levers to a connecting rod encompassing an eccentric, having grooves for moving the radial spur and mounted on a reversing shaft, a software kinematically associated with a key, and means for fixing the eccentric in extreme poli x.

In this heald carriage, the connection between the reversing shaft, eccentric and connecting rod is carried out with the help of crackers and springs, which, due to vibrations in the loom, do not provide a sufficiently reliable operation of the mechanisms.

In the proposed heald carriage, a rigid connection is established in the lever control, for which means for fixing the eccentric in it are made in the form of a glass with diametrically opposite grooves, rigidly connected to the mechanism housing and interacting with a key having slots in mutually perpendicular planes, A software kinematic link with a key consists of two three-arm levers connected to each other for simultaneous removal or approaching the reversing shaft.

FIG. Figure 1 shows the proposed slide carriage during the connection of the eccentric with the reversing shaft of the help key; pa fpg. 2 - karetkl prp p dvnonov shnonka from meshes with reversh; FIG. 3 - the position of the pins during its movement in conjunction with the means for fixing the eccentric; in fig. 4-, section A-A in FIG. 3; in fig. 5 - Affinity for fixing the eccentric, kind of sweet; in fig. 6 - frontal view.

The remizoupovaya mechanism includes a reversing shaft / (Fig. 1), driven in two) from the main shaft of the weaving machine. Oh

the shaft /, which has two diametrically spaced groove 2, freely mounted an eccentric 3, also having a radial groove 4 and an annular groove 5. For fixing the eccentric 3 in the extreme positions of

the latch b, made in the form of a glass, which fits into the annular groove 5 of the eccentric 3. The latch 6 is freely mounted on the shaft, and its stationary position relative to the shaft / is provided with a finger 7, which is included in the latch groove 8 and rigidly connected to the housing not shown in the drawing) mechanism.

which is mounted on axis 14 and is connected via upper arm 15 with double-arm lever 16. The latter is in contact with peg 17 of program carrier 18 and mounted on a common axis 19 with second three-arm lever 20, which first arm contacts with peg 21 of program carrier 18, second shoulder through the slot and the finger 22 is connected to the three-arm lever 13, and the third shoulder through the bushing 23 contacts the key 9 in the second extreme position of the eccentric 3 (Fig. 2).

On the eccentric 3 freely set the rod 24, which is connected by plates 25 to the lever 26, transmitting the movement to the heddle frame. On the connecting rod on both sides there are fasteners 27, which prevent the eccentric from shifting during installation and provide contact. adjacent rods.

The retainer glass b (Fgn. 5) has annular protrusions 28 entering the annular groove of the eccentric, and the diametrically lateral grooves 29 serve as guides when moving the key 9 with levers 13 and 20. Inclined pads 30 serve to prevent the key from jamming.

During the operation of the loom, the hedging frame switching is determined by the program carrier with pegs 17 and 21.

The upper arm of the peg (7) lifts the lever 6 and through the tr 15 and rotates the three-arm 13, which inserts the key 9 along the guides of the groove 4 of the eccentric 3 and through the groove of the retainer 6 into engagement with the shaft /. At the same time, the pinch 23 of the triple arm 20, connected with the three-arm J3, enters the dark groove of the retainer 6.

By turning the reversing shaft 1 the next time, the eccentric turns with the shaft and moves the connecting rod, causing the position of the heddle frame to change. If after changing the position of the frame it

must stand, the program carrier 18 brings the peg 21 under the lever 20, which leads the key 9 out of the groove 2 of the reversing shaft 1, while the key continues to remain in the eccentric and retainer connected to the housing, and accurately fixes the position of the eccentric 3 relative to the shaft /, which allows to engage the key with the shaft during the subsequent mixing of the helix frame.

Subject invention

Remizable carriage to weaving machine containing heddle frames associated with

by means of a lever system with a tongue covering an eccentric, having means for moving a radial key n mounted on a reversing shaft, a software tool kinematically connected with a spore, and means for fixing the eccentric in extreme positions, so as to increase reliability of the mechanism, the means for fixing the eccentric is made in the form of a glass with a diametrically

opposite grooves, rigidly connected with the body of the mechanism and interacting with the key, having grooves in mutually perpendicular planes, and the kinematic connection of the software

A key is a pair of three-shoulder arms connected to each other for simultaneous removal or bringing them closer to the reversing shaft.
