Description

The invention relates to devices for programmatically controlling the process of forming fabrics on a weaving fabric; | kih machines and concerns the design of | knife. climbing carriages with electronically controlled movement of the shaft.

The aim of the invention is to simplify the design and increase reliability in operation.

Figure 1 shows the kinematic diagram of the device; figure 2 - profile of the protrusion of the hook.

The knives helix carriage contains (Fig. 1) hooks 1, kinematically connected on one side by means of balances 2 and levers 3 to the looms of the loom, and on the other hand having upper bearing surface 4 for engagement with the anvil 5 and the lower profiled surface 6 for interacting with the power knife 7 ,. electromagnets 8 according to the number of hooks .1, the measles 9 of each of which are kinematically connected with the rod 10 installed with the possibility of horizontal movement and interaction with the protrusion 11 connecting the upper bearing surface 4 and the lower profiled surface 6 of the hook 1, as well as springs 12 and 13 and software control electronic unit 14.

The protrusion 11 has a stepped shape (Fig. 2), the upper surface a and the lower surface b of which are arranged parallel and inclined to the horizontal surface connecting them c.

Knife heddle-carriage works as follows.

During a stand-up period, the hook 1 is held in the upper position, abutting the upper support surface 4 against the support 5 and the horizontal surface from the protrusion 11 onto the rod 10.

When turning clockwise of the power knife 7, the latter rotates the hook 1, forming a gap between the horizontal surface of the hook 1 and the brush 10. The bottom surface b of the protrusion 11 acts on the rod 1 O and presses the measles 9 to the electromagnet 8. If

The electromagnet 8 from the output of the software control electronic unit 14 will be given a control signal, then the rod 10 will remain attracted to the electromagnet 8 and when the box knife 7 moves counterclockwise, the hook 1 will move downwards under the influence of the spring 13 contact with the power knife 7, and through the balancer 2 and the system of levers 3 will set in motion the corresponding heald.

If no signal is supplied to the electromagnet 8 from the output of the software control unit 14, the spring 12 will return the rod 10 and, accordingly, the measles 9 to the initial position, the horizontal surface, from the protrusion 11 will come into contact with the rod 10 and the hook 1 will be held in the upper position.

When you return the power knife 7 with the hook 1 to its original position, the upper surface ct of the protrusion 1 1 acts on the brush 10, moving it to the left, and presses the measles 9 to the electromagnet 8.

Claims (1)

Invention Formula A knives helix carriage containing hooks, each of which, on the one hand, is kinematically connected by means of a balancer to heaves, and on the other hand, has an upper bearing surface for interacting with the abutment and a lower profiled surface for interacting with the power knife by a connecting protrusion, and Also, according to the number of hooks, electromagnets, electrically connected with the electronic program control unit, are different in that, in order to simplify the design and increase reliability in operation, the hook protrusion has t stepped shape, the upper and lower surfaces of which are arranged parallel and obliquely to a connecting their horizontal po- .verhnosti, and an electromagnet is mounted in a zone of the trajectory of movement of the hook protrusion to cooperate with it armature of the electromagnet. eleven Fi & .2
