Description

[Detailed description of the invention] The present invention has a large number of yarn reeling sections, and a detection device for detecting the tension of four yarns on the reeling path of each yarn reeling section. Even when a minute abnormal tension is detected, the small frame stopping device is activated in conjunction with the ratchet wheel which is rotated by an external force in conjunction with this to stop the reel, and the minute tension is detected. The present invention relates to a yarn reeling tension detection device for a yarn reeling machine that can easily and accurately adjust changes in yarn reeling tension.

The purpose of the present invention is to obtain a device that can perform such adjustment, and is provided with a large number of reeling sections 1, and each reeling section 1
A fineness sensing device 2 and a yarn reeling tension sensing device 3 are installed on the yarn reeling path.
and when the yarn reeling tension detection device 3 detects abnormal tension, the yarn reeling stop device 4 is operated in conjunction with the ratchet wheel 27 which is rotated by an external force in conjunction with the yarn reeling tension detection device 3. The yarn reeling tension detecting device 3 is constructed of a balance 8 having a drum wheel 6 on one side of the lever 5 for hanging four threads, and a weight 7 on the other side for balancing the tension applied to the drum wheel 6. A rough adjustment weight 10 that can be removably locked to a large number of locking portions 9 provided along the length direction of the lever 5, It is characterized by being constructed with a fine adjustment chain 12 whose ends are connected and the other end is connected to an adjuster 11 common to each reeling section 1 to freely adjust the suspension length.

As shown in FIGS. 1 and 2, one end of the chain 12 is connected to a worm wheel 14 serving as an adjuster 11 provided on a rotating shaft 13 common to each reeling section 1 to rotate the rotating shaft 13. , by hoisting the chain 12 onto the worm wheel 14 to adjust its hanging length, or as an adjuster 11 as shown in FIG.
One end is connected to a sliding plate 15 that is slidable along the arrangement direction of each reeling section 1, so that the hanging length thereof can be adjusted.

In the case shown in FIG. 1 and FIG.
A finger board 19 is provided through the rotary shaft 13 so that the winding amount of the chain 12 can be read from the rotational position of the rotary shaft 13.

Note that 20 indicates a guideline. The reeling stop device 4 connects the reel frames 21 and 1
A brake wheel 23 contacts a friction side 22 provided on the body, and the brake wheel 23 is normally connected to the friction side 2 against a spring 24.
When an abnormal tension is detected in the locking mechanism 25 that locks the yarn in a state separated from the yarn reeling tension detection device 3, the locking mechanism 2
The operating mechanism 26 has a claw 27a at the tip facing above the rook 27 which is constantly being driven and rotated, and the root part is connected to the tension detecting device. 3, and a swinging rod 31 equipped with a pin 31a that engages with a hook portion 30a provided on the hook rod 30 constituting the locking mechanism 25. The pawl rod 29 is connected to the upper end of the swing rod 31, and when the tension detection device 3 detects an abnormal tension and the rod oscillates, the continuous piece 28 pushes up the root of the pawl rod 29, causing the rook 27 This causes the swinging rod 31 to swing.
The pin 31 a is separated from the hook portion 30 a so that the brake wheel 23 is brought into pressure contact with the friction side 22 .

In the drawing, reference numeral 32 indicates a fineness indicating pin provided on the fineness sensor provided at the zero reeling thread, 34 indicates a search claw for searching the indicating pin, and 35
is an entangling rod.

This device selects one of the many locking positions provided along the length of the lever and locks the weight, thereby reducing yarn reeling to zero.
Coarse adjustments can be made to change the fineness of the yarn, while fine adjustments such as reeling speed, hot water temperature, and image quality can be made by adjusting the hanging length of the chain.

In this way, according to the present invention, the abnormal tension detected by the reeling tension detection device changes the system that directly activates the stop device of the small frame due to its operation to one that does not sufficiently stop the small frame due to minute fluctuations in tension. When making a large adjustment such as changing the fineness of 0 reeling yarn in a device that operates a stop device in connection with a rook that rotates due to an external force even when there is a slight change in tension caused by increasing the grain by one or two grains. The hanging length of the chain can be adjusted by adjusting the tension using a weight for coarse adjustment, and finely adjusting the tension by adjusting the reeling conditions in the middle of the adjustment stage, and the combination of these makes it easy to adjust the tension. Fine adjustments can also be made easily and accurately.

Conventionally, the adjustment is made only by adjusting the length of the chain.
Naturally, the suspended length of the chain becomes longer, which makes operation cumbersome and interferes with management work in the reeling section, but it is possible to use a weight for coarse adjustment and a relatively short chain for minute tension adjustment. When used in combination, such inconvenience does not occur, the operation is simple and accurate adjustment is possible, and the small frame can be stopped accurately even in response to minute fluctuations.
