SU343603A1 - DEVICE FOR CHARGING SIDES ON MULTI-GROUND - Google Patents

Description

A device for charging spools on multi-weaving looms is known, comprising weft yarn feeders, a drive rail interacting with shnuli, and a return conveyor carrying shuttles.

In order to get the winding speed of the thread on the shuttle bobbin, which is close to the speed of gathering the thread when weaving, regardless of the width of the machine, the proposed device is equipped with a feeding conveyor carrying weft yarns and located across the entire width of the machine refueling parallel to the return conveyor with the possibility of moving synchronously with the latter and driving gear the rail is fastened along the return conveyor also across the entire width of the machine refueling.

The hook body has a side slot for exit of the weft yarn and a groove to allow the spool to engage with the drive rail.

The spool is made in the form of a toothed disk equipped with pins spaced perpendicularly along its periphery to its base.

FIG. 1 shows a preferred device for charging Nshul, side view; in fig. 2 shows a general scheme for charging shuttles and laying a weft on a loom; in fig. 3 - view of the shuttle with shpuley; in fig. 4 - the same.

view from above; in fig. 5 - cross section at the point of engagement of the bobbin of the shuttle with the drive rail. The proposed device contains weft yarn feeders 1, shuttles 2, on axis 3, each of KOTOpijix has npool 4, drive rail 5 and returning conveyor 6. Behind each shuttle there are grippers 7 weft yarns installed on the conveyor.

The rail 5 is located on one side of the transnorter 6 parallel to it and passes across the entire width of the filling station. Parallel to the returning transnoru 6 there is a feeding conveyor 8, pa which

using holders 9, weft packs 10 are installed. The intervals between weft packs correspond to the intervals between the shuttles on the return conveyor. Pa holder 9 are located peephole 11 dl

weft thread 12, brake 13, made, for example, in the form of spring-loaded nlastin, grip 14 and thread supporter 15. Feeder 15 is made in the form of a lever 16 with an eye for the weft thread and a roll 17, interacting with slide 18.

The machine also has weft scissors 19, located at the turn of return 1}, its transnorter 6, and weft grip 20 installed at the edge of the fabric from the entrance of the cel. Corps 22 of the shuttle 2 has a slot 23 for entering the weft thread. In the lower plane of the housing 22, an axis 3 is installed to accommodate the spool 4. The Schnul is made in the form of a gear disk 24 with vertical pins 25 and is mounted on the axis 3 rotatably. Through the groove 26, which is located in the body of the shuttle, the disk of the spool 24 interacts with the rail 5. In order to maintain the constant tension of the weft yarn during the fabrication process, the brake 27 is installed in the shuttle.

During the operation of the machine, the shuttle leaves the tissue-forming device 21 and is fed to the return conveyor 6. The weft packs 10 that are installed on the feed conveyor 8 move synchronously with the shuttles. The weft end of each pack is positioned above the shuttle (perpendicular to the shuttle line) using a hook 14, the brakes 13 and the yarn feeder 15. When the weft thread is charged into the shuttle, the yarn feeder 15 drives the weft thread into the slot of the shuttle 23 and into the spool zone 4. When the shuttle moves, along with the returning spool, 4 spools modifies with rail 5 and rotates. Here, the weft thread is wound on vertical pins 25. After the weft thread is secured to the spool, the thread is pulled out of the spring-loaded gripper 14 by means of a cylindrical protrusion 28 on the spool. The winding of the weft yarn onto the spool continues throughout the entire straight section of the conveyor belt, the length of which corresponds to the width of the weaving dressing station).

At the end of the rectilinear section of the conveyor 6, the spool 4 is disengaged from the rail 5, and the winding of the weft yarn onto the spool is stopped. At the turns of the returning and feeding conveyors, where their adjacent branches disperse, the weft thread is gripped respectively by the gripper 14 On the Feeding conveyor and the gripper 7 on the return conveyor and is cut by the weft scissors 19.

After entering the shuttle into the tissue-forming device, the end of the weft yarn is caught by the weft grip 20. During the tissue formation, the tension of the weft yarn in the shuttle is maintained by the brake 27.

Subject invention
