BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation confirmation device used in a textile machine such as a yarn splicing device for a doubling machine to confirm whether a predetermined operation has been reliably executed.

0002

[Prior Art] Conventionally, when performing a work consisting of a series of operations in a textile machine, for example, when splicing yarn in an automatic winder, it is necessary to use a suction mouth to pull out the side yarn of the winding package. After performing a series of actions, the success or failure of achieving the goal is confirmed, and if the goal is not achieved, the entire series of actions is performed again from the beginning.

0003

[Problem to be Solved by the Invention] In textile machines that confirm the success or failure of achieving the goal after performing a series of operations as described above, the several successful operations before the failed operation are completely wasted. This poses a problem of wasting time and energy.

SUMMARY OF THE INVENTION An object of the present invention is to provide an operation confirmation device for a textile machine that checks each operation of the textile machine each time and proceeds to the next operation, thereby eliminating waste of time and energy.

[0005]

[Means for Solving the Problems] In order to achieve the above object, an operation confirmation device for a textile machine according to the present invention includes a cam having a recess corresponding to each operation of one operation, and a cam corresponding to each recess of the cam. It consists of a cam rotation motor that stops and then releases the stop when an operation success signal is received.

[0006]

[Operation] In the operation confirmation device for textile machinery configured as described above, the motor that rotates the cam is stopped for each operation in a certain operation of the textile machine, and the operation and success or failure of the operation can be confirmed. It will be done. When the operation is successful and an operation success signal is issued, the motor that rotates the cam is released from its stop, rotates, and moves on to the next operation.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which the operation confirmation device of the present invention is applied to a yarn splicing device for a yarn doubling machine will be described with reference to FIGS. 1 to 7.

First, the yarn doubling machine will be explained. The yarn doubling machine has a similar structure to an automatic winder, but differs greatly in that it has two yarn feeding packages. That is, the basic structure of the yarn doubling machine is that, as shown in FIGS. 1 and 2, yarns pulled out from two yarn supply packages 1 and 2 pass through balloon breakers 12 and 12 to a tensor 15, where they are combined. It is wound onto a winding package 3 while being traversed by a traversing drum 4.

What is shown by the two-dot chain line in FIGS. 1 and 2 is the process of doffing and splicing of the winding package in the unit that moves along the units of a plurality of yarn doubling machines installed in parallel, and that has become a full tube. This is a processing robot R.

[0010] The processing robot R has a suction mouse 5,
It is equipped with a relay pipe 6, a thread splicing device 7, a thread separating device 8 for upper thread, and a thread separating device 9 for lower thread.

The yarn splicing device 7 is composed of a knotter, a splicer, etc., and the left and right yarn splicing devices 7 are installed vertically offset, so that each yarn splice is shifted back and forth.

When a thread breakage is detected by the thread breakage sensor 13 when a package is replaced or a thread breaks, the processing robot R moves by itself to the unit. The suction mouth 5 is a unit that suctions the yarn on the winding package 3 side, rotates downward, and guides it to the yarn splicing device 7 side.

At this time, the needle thread separating device 8 operates to separate the two threads wound around the winding package 3 into left and right sides, and each thread is guided into each thread splicing device 7.

As shown in FIG. 3, the needle thread separating device 8 includes a box 17 with a built-in air cylinder and a box 1.
7 and two left and right arms 18, 18 which are swung by an air cylinder, and a fixed clamping piece 1 fixed to each arm 18.
9, and a swinging clamping piece 20 swingably supported by each arm 18.
and stoppers 21 and 22 located on both sides of the swinging clamping piece 20 to control its swinging, and is normally on standby in the state shown in FIG.

The swinging clamping piece 20 includes a protruding piece 20a that cooperates with the fixed clamping piece 19 to clamp the upper thread, a protruding piece 20b that comes into contact with the inner stopper 21 when the arm 18 swings inward,
It consists of a protruding piece 20c that comes into contact with the outer stopper 22 when the arm 18 swings outward. When the upper thread is guided to the thread splicing device 7 side by the suction mouth 5, the arm 1
8 swings inward, and the protruding piece 20b contacts the stopper 21 and swings. As a result, the protruding pieces 20a open relative to the fixed clamping pieces 19, and each needle thread is held in its valley. Thereafter, the arm 18 swings outward, and the protruding piece 20c contacts the stopper 22 and swings. As a result, the projecting pieces 20a close against the fixed clamping pieces 19, each pinching one needle thread, and each needle thread is separated into left and right sides. The yarn detection feeler 23 determines whether or not separation is possible.

A blow-up nozzle 10 that blows out compressed air from below into the hollow part of the bobbin is connected to the support parts of the yarn feeding packages 1 and 2 of this yarn doubling device. The yarn ends contained in the bobbin hollows of the yarn packages 1, 2 are conveyed to the balloon breaker 12.

An auxiliary blow-up nozzle 11 that blows compressed air upward is opened inside the balloon breaker 12.
Each bobbin thread carried by the blow-up nozzle 10 is blown up to a thread guide 14.

The relay pipe 6 has two suction openings, and is connected between the yarn supply packages 1 and 2 and the yarn splicing device 7.
It is provided so that it can be rotated up and down. When replacing the package or when the yarn breaks, close the suction opening to yarn feeding package 1,
2 side so that the suction opening is located above the thread guide 14. At this position, when the auxiliary blow-up nozzle 11 suctions the yarn from the yarn feeding packages 1 and 2, the relay pipe 6 rotates upward while holding each bobbin yarn, and transfers each bobbin yarn to the yarn splicing device 7 side. I will guide you to.

At this time, the bobbin thread separating device 9 operates to separate each yarn of each yarn supply package into left and right parts, and each yarn is guided into each yarn splicing device 7.

As shown in FIG. 4, the bobbin thread separating device 9 includes a yarn guide 2 having a bobbin thread receiving portion recessed in the center.
4, and an inverted L-shaped separate guide 25 that is swingably supported around a vertical shaft 26 and has a pointed end 25a at its free end.
4, and is normally on standby in the state shown in FIG.

When the bobbin thread is guided to the yarn splicing device 7 side by the relay pipe 6, the gaps between each member of the tensor 15 are opened, and the separate guide 25 is rotated in the direction of the arrow by an appropriate driving means to reduce the mutual spacing. The pointed end 25a is inserted between each bobbin thread with a slight gap between them. As a result, each bobbin thread is separated into left and right sides.

When the yarns from the yarn supplying packages 1 and 2 are thus introduced into the yarn splicing device 9, the yarn from the winding package 3, which has been previously introduced into the yarn splicing device 9 by the suction mouth 5, is transferred to the yarn splicing device 9. Along with this, the threads are spliced. Note that 16 is a yarn cutter, which is operated during yarn splicing, as in an automatic winder.

Next, the operation confirmation device of the present invention will be explained.

As shown in FIG. 5, this device includes a controller 27, a motor 28 controlled by the controller 27, a cam 29 fixed to the rotating shaft of the motor 28, and a switch 3 whose opening and closing are controlled by the cam 29.
It consists of 0 mag.

The cam 29 has recesses 29a corresponding to the origin, taking out the winding package, separating the upper thread, etc.
29b, -- are formed.

The switch 30 is always biased toward the cam 29 by a spring 33, and is opened and closed by an L-shaped swinging arm 31 that is swingably supported on a shaft 32. Swing arm 31
At the end of one arm, there is a roller 34 as a cam follower.
is attached, and the other arm is an operating arm for the switch 30. As shown in FIG. 7, each recess 29a, 2 of the cam 29
In response to 9b, ---, the switch 30 is turned off, the signal is sent to the controller 27, and the motor 28 stops rotating.

While the motor 28 is stopped, operations such as opening and checking the winding package, separating the upper thread, and checking it are performed. For example, confirmation of the opening of the winding package is performed by the thread detection feeler 35 that detects the passage of the thread in the suction mouth 5 as shown in FIG. 6, and confirmation of upper thread separation is made by the thread detection feeler 23 shown in FIG. done by. Each operation can be repeated several times until successful. As shown in FIG. 5, signals indicating successful operation from the thread detection feelers 23, 35, etc.
7, and a stop release signal is sent from the controller 27 to the motor 28.
