JPS606051Y2 - Multi-striatal equal tension delivery braking device - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a braking device that can send out a plurality of filamentary bodies simultaneously and with equal tension.

For example, in the case of extruding the coating of electric wires, when multiple wires are laid, the plurality of core wires passing through a multiple extrusion head must be made to have equal tension at the entrance of the extrusion head or the like.

For this reason, normally an independently adjustable braking device is grounded on the delivery side of each core wire, and a dancer roll (
However, with such delivery braking means, the adjustment operation is complicated, there are many devices, and the installation area is large. If it is too large or too small, it has the disadvantage that it tends to create an unbalanced tension state.

In view of these points, this invention has a simple structure, simple operation, etc.
It was designed to provide a device that can automatically control the tension fluctuations that occur between the striatum and deliver the same tension.
It is characterized by incorporating a differential gear device with a brake device installed on the input side between the shafts of the capstan that takes over and sends out the filament.

This will be explained with reference to the accompanying drawings. FIG. 1 shows a case in which the device according to the invention is applied to a double-hook extrusion line for electric wires, and 5 is a delivery braking device.

This device 5 includes core wires 3 fed out from feeders 1 and 2, respectively.
, 4 pass through the two extrusion heads 7 of the extruder 6, and enter the cooling water tank 8.
, in the process of being wound up by the winding machines 10 and 11 through the winding machine 9, each capstan 12 and 18 is disposed between the sending machines 1 and 2 and the extruder 6, as shown in FIG. The core wires 3 and 4 are wound halfway around the outer periphery of the wire.

Each capstan 12.13 is as shown in FIG.
The capstans 12.13 are arranged in parallel at a predetermined distance, and on opposite sides of the capstans 12.13 are first and second capstans connected at one end thereof to the capstan 12.13. A shaft 14.15 is provided.

The other ends of the first and second shafts 14.15 each have a first
and a second gear 23, 24 are connected, and a pair of planetary gears 16, 17 are meshed between the first and second gears 23, 24.

The planetary gears 16,17 are pivotally connected to the frame 18 via shafts 160,170.

The frame 18 is connected to a side surface of a fifth gear 19 rotatably mounted on the circumference of the first shaft 14 .

A sixth gear 20 is meshed with the fifth gear 19, and a third shaft 21 is connected to the sixth gear 20.
A brake device 22 is attached via.

In such a configuration, when the line is operated and the tension of the core wires 3.4 is equal, the differential mechanism is locked and the first and second
The third shafts 14, 15, and 21 and the frame 18 rotate together, and can send out the core wires 3, 4 while maintaining the tension of the core wires 3, 4 at a value predetermined by the brake device 22. can.

If the tension in the core wire 3 on the capstan 12 side increases in the rear row, the speed of the capstan 12 increases and the speed of the capstan 13 decreases accordingly.

As a result, the tension of the core wire 4 on the capstan 13 side increases, and can automatically follow the tension of the core wire 3.

In this way, with this device, it is possible to automatically control the difference in tension between the striatum using a simple device, for example, to keep two striatum in a stable state at all times. It has the advantage of being able to be sent out simultaneously, and its practical effects are extremely large.

In addition, when sending out a large number of two or more linear bodies at the same time, a device as shown in FIG. It can be used by connecting it to a brake device via a transmission device.
