Description

[Detailed Description of the Invention] [Background and Purpose of the Invention] The present invention relates to a tension adjustment device during delivery of a plurality of filaments.

Conventionally, there is no need to add twisting to the sending wires as in take-up rotary type collecting machines and SZ collecting machines, and in sending out systems where the sending device does not twist and rotate, the untwisting Since there is no need to rotate,
A fairly simple type of delivery device is often used. If it is necessary to send out a large number of filaments, the drawn length of the filament from each feeder may be particularly short, or conversely, due to the location, etc., the filament must pass a long distance through guide rolls, dies, etc. Problems have arisen in which the sending force at the final assembly section becomes large due to unsteady cables, the cables come apart and the assembled cables become wavy, and the outer diameter fluctuates. In addition, in order to eliminate the unreasonableness of having a large number of dedicated transmitters at all times, such as when a similar problem occurs with a large number of transmitting lines, a transmitter of a different type is used to reuse transmitters from other mechanical devices only at that time. It also occurred during work. As a result, work was carried out at the expense of the speed of the main line.

The present invention was created in view of the above situation, and provides a device for adjusting the sending force of multiple strands, which can adjust, reduce and stabilize the sending force of a plurality of strands, and improve product performance and work efficiency. It is intended for this purpose.

[Summary of the invention] The device for adjusting the delivery force for multiple filaments of the present invention is to adjust the delivery force of a plurality of filaments to a drive shaft that is rotationally driven by a motor so that the filament velocity is slightly faster than the delivery speed of each filament. A striatal body feeding pulley is fixed, and each of the filamentous bodies is wound around the respective filamentous body feeding pulley for about one rotation, and the individual tension of each of the filamentous bodies is adjusted through a rotation speed adjusting means. a plurality of the above-mentioned linear body feeding pulleys, and a guide die and a guide arranged to respectively guide the linear bodies to the above-mentioned respective linear body inlet and exit positions of each of the linear body feeding pulleys. It is equipped with a pulley.

[Example] Hereinafter, the device for adjusting the feeding force for multiple filaments of the present invention will be explained using an example with reference to FIGS. 1 and 2. FIG. 1 is a plan view of a feeding force adjusting device including five sets of linear body feeding pulleys, and FIG. 2 is a detailed view of the linear body feeding pulley shown in FIG. In the figure, 1 is a wire body, 2 is a motor, 3 is a drive shaft, 4 is a screw shaft, 5 is an adjustment nut, 6 is a spring, 7 is a friction plate, 8 is a wire feed pulley, 9 is a bearing, 10 is a retaining ring. 11

Reference numeral 5 designates a whiskering delivery device, 16 a breaker type delivery device, 18 a striatal body delivery device, 19 a control box, and 20 a dancer.

Figure 2 shows the feed pulley part that reduces the tension on the filament 1. A screw shaft 4 fixed with a key is attached to the drive shaft 3, and the screw shaft 4 has a smooth shaft in the axial direction. A friction plate 7 is attached that is movable but restricted in the direction of rotation and is secured by a key. The friction plate 7 includes an adjustment nut 5 that is screwed onto the screw shaft 4 and is formed so that the screwing position can be adjusted, and the friction plate 7.
The drive shaft 3 is pressed by the tension of a spring 6 attached between the drive shaft 3 and the linear body feeding pulley 8, and the rotation of the drive shaft 3 is transmitted to the linear body feeding pulley 8.
The linear feed pulley 8 is configured to receive driving force only by the contact resistance of the friction plate 7, and is rotatably attached to the drive shaft 3 via a bearing 9, and its dimensions are adjusted by a spacer 13. Retaining ring 1
The axial direction is fixed by 0. Therefore, by adjusting the rotation of the adjusting nut 5, the drive shaft 3 can be adjusted.
The rotational speed is transmitted to the linear body feed pulley 8 through the friction plate 7 in an adjustable manner. The adjusting nut 5, the spring 6, the friction plate 7, etc. form a rotation speed adjusting means.

In FIG. 1, a filamentous body 1 is fed to each filamentous body feeding pulley 8, and each filamentous body feeding pulley 8 is fed through a drive shaft 3 by a motor 2 of a filamentous body feeding device 18. It is becoming driven. At the front and rear of each striated body feed pulley 8, the filament bodies 1, each of which is wound one turn around the filament body feed pulley 8 by a guide die 11 and a guide pulley 12 as shown in FIG. The guide is configured to prevent entanglement. When a large number of striatum bodies are to be sent out at an actual work site, a forced delivery device with a dancer 14, a whisker ring delivery device 15,
Quite often it is necessary to use various delivery devices, such as a brake-type delivery machine 16. In that case, in order to keep the tension of each wire constant, the filament body 1 having a strong tension is drawn into the filament body feeding pulley 8 through the filament body feeding device 18, and the tension is maintained at a low and stable level for the next process. It is now being fed into a machine.

A method for reducing and stabilizing the tension in the striatal body 1 will be explained with reference to FIG. The filament 1 is wound around a filament feed pulley 8 driven by a motor 2, and guided by a guide die 11, a guide pulley 12, and the like. If the sending force is T ₀ , the striatal body feeding pulley 8
, the tension force T ₂ = T ₀ − _{T 1} is generated by the tension force T ₁ that pulls the filament 1 after adjustment by the friction plate 7 to which the driving force is applied by the motor 2. It is relieved and goes out. Of course, for this purpose, the linear body speed V ₁ of the next process machine and the circumferential speed V ₀ at which the linear body feeding pulley 8 is driven by the motor 2 must be such that V ₀ >
A relationship of V ₁ is required. When the motor 2 is variable speed, the circumferential speed of V ₀ follows it even if V ₁ changes, and the transmission relationship is such that the above relationship is always maintained.
If the motor 2 has a constant speed, it is necessary to establish a conduction relationship such that the speed of _V0 is greater than the maximum speed of _V1 . The tension of the striatum 1 is adjusted as described above.

Since the multi-striate body feeding force adjustment device of this embodiment is configured in this manner, the following feeding operation can be performed.

(1) Even with a simple delivery device that cannot produce low tension, by using this device, stable delivery work can be performed with low tension.

(2) It can be used for sending out several different types of models and can perform a large number of sending operations.

(3) This device can keep the tension constant and send out the tension that varies depending on the conditions of each filament. Furthermore, the filamentous body that enters the apparatus with the same tension can be sent out with the tension required by the next process machine.

(4) Any of the operations (1) to (3) above can be performed with a high-performance delivery device, such as a forced delivery device with tension control, an electrically controlled brake delivery device, etc. Considering that the device is installed in each body, there are disadvantages such as not only the cost becomes extremely high, but also the installation space becomes extremely large.

(5) If you try to increase the speed with a simple delivery device, excessive tension will occur, resulting in unstable delivery and limiting the speed, but in this example, the tension is reduced, stable tension is delivered, and high-speed delivery is possible. It is possible.

In the above example, the sending force varies,
I explained that the tension is reduced to a weak and stable constant tension, but for example, out of the many filaments that come out of the sending machine, only some of them travel a long distance and pass through many guides, so the tension is reduced. In anticipation of the tension becoming excessive, the tension may be weakened by that amount in advance. In addition, when it is desired to partially change the tension in a twisted set of electric wires and cables, etc., for example, when twisting the inner layer and the outer layer with the same feeding tension, the return effect due to the tension and the stiffness of the cable Due to the return action and geometric dimensions, the twist rate of the outer layer is large and the inner layer is reduced. Therefore, the sending force of the inner layer cable is reduced and stabilized in advance to operate with low tension. As a result, the twisting rate of the twisted cable can be brought closer to that of the outer layer, and the work can be carried out more efficiently.

[Effects of the invention] As described above, the device for adjusting the sending force of multiple filaments of the present invention has the effect of adjusting the sending force of multiple filaments, reducing and stabilizing it, and improving product performance and work efficiency. It is.
