Fully Automatic Balling Machine HK

Fully Automatic Balling Machine HK

Description

The electronically controlled Automatic Balling Machine HK with 6, 9 or 12 spindles processes in a fully automatic working cycle twines, strings and cords into balls of all common shapes within a weight range from 5 to 2000 grams (HK-6), 1500 grams (HK-9) or 500 grams (HK-12).

When starting the winding cycle the flyer makes a half turn and puts the twine in front of the winding mandrel. The slotted mandrel moves forward into winding position and threads the twine. After a few turns of the flyer the thread clamp releases the beginning of the twine which is then wound into the ball. All ball shapes and structures are infinitely adjustable through a raising and lowering of the mandrel beam. During the base winding the mandrel runs with increased speed. This results in a large twine laying grid and an increased ball volume. During the surface layer winding an automatic decrease of the mandrel speed results into a closed twine layer on the surface of the finished ball. The ratio mandrel revolutions to flyer revolutions can be adjusted at any mandrel beam position and stored into the operation panel storage place. With this option you can also produce “square” balls. The final circumference winding consists of parallel layers side by side on the surface of the ball. Optional there is the possibility to insert a label, tied down with the final circumference winding. The end of the twine is led into the insert hook and put into the open knife of the cutting device. The knife moves backwards, cuts the twine and at the same time clamps the twine-end for the next winding cycle. The insert hook moves backwards and draws in the twine in loop shape under the circumference winding. The winding cycle is finished and the ball is doffed with a draw- back movement of the winding mandrel.

All ball parameters like running-length mandrel-beam-position, winding speed etc. can be stored in up to 99 storage places for shortest change-over-times.

Hank Winding Machine DO-1 / DO-2 / DO-3

The electronic controled Hank Winding Machine DO 1 is processing cords/ropes automatically within a diameter from 2 to 14 mm. It is possible to produce hanks with a length 150 – 400 mm (inside length = distance of the winding hooks).

At the beginning of a cycle the material will be wound arround both winding hooks to reduce the rope tension, affecting the pliers. The winding process is turning counter clockwise. The number of revolutions for the body layer is adjustable at the touch panel. During the winding of the body layer the horizontal traversing (driven by a servo motor) is active. The horizontal traversing gives the rope loops a position side by side on the winding hooks. The width of the horizontal traversing is adjustable, just as the speed of the winding process. If the body layer has reached the number of set revolutions, the machine is preparing to start the belly layer. The transition from the body layer to the belly layer is done by the interaction of the horizontal traversing drive and the main drive. After this transition the body layer is fixed and it is possible to process the belly layer without loosening the body layer. The belly layer is processed by the interaction of the main drive (vertical traversing) and the winding hook drive. During the turning of the winding hooks, the main drive moves along the hank upwards (= vertical traversing). Beginning with the start position of the main drive the winding hooks are turning synchronously to the movement of the main drive until the stop position of the main drive is reached. After setting the winding hook drive to the basic position the main drive is turning above the upper winding hook. In this position the inserting needle is coming out and is moving through the hank. The notch of the needle becomes visible on the other side of the hank. The main drive is moving back to the cutting position and the needle is fixing the material. The pliers are coming up to fix the material too. The cutting device (cold or hot cutting) is coming down and cuts the material between the two fix points. After that the needle pulls the rope end backwards through the hank. The machine doffs the hank and tranports it out with the exit conveyor belt.
