Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to, for example, a defective portion of a filament or a measuring end portion of the filament sent from a filament manufacturing process, which is applied to a winding machine. The present invention relates to a marking device for a filament winding device, which enables easy identification of a portion wound on a main body.

(Prior Art) Generally, when there is a defect in the filament, the defect is detected and an alarm is activated to notify the operator. However, this defect may be caught in the winder body. Many. For this reason, since the operator visually or visually confirms this defective portion, the workability is low. For this reason, there has recently been proposed an apparatus for automatically marking a defective portion on the linear body by applying or spraying a magic ink on the defective portion (see, for example, JP-A-58-168433).
However, in this device, when the magic ink is wound inside the winder main body, it adheres to the non-defective parts of the adjacent filaments, and the marked part is hidden after a lapse of time after the marked part is rolled up. It became difficult to find the defective part, and it was sometimes overlooked and shipped as a good product. In addition, in order to cut the linear body to a fixed length, it may be required to mark the linear body.
Even in this case, the conventional technique has the same drawback.

(Object of the Invention) An object of the present invention is to easily confirm even if a marking portion of a filament does not stain other filament portions and the marking portion is wound into the winder body. It is an object of the present invention to provide a marking device for a filament winding machine capable of performing the above.

(Structure of the Invention) A marking device for a filament winding machine according to the present invention includes a marking tube which is provided in front of a winding machine body and which is penetrated by a filament body running toward the winding machine body. Together with a support member that supports the support member so as not to move together, a holding means that normally holds this support member in a position that supports the marking tube, and a support member when the portion of the filament to be marked reaches the support member. Marking command means for driving the holding means so as to allow the marking tube to move together with the linear body by releasing the marking tube from the supporting position.

In this way, since the marking tube is covered by the marking tube on the part to be marked on the filament, the marking part of the filament is covered by other parts like the conventional technique of marking with magic ink or paint. The filamentous portion is not contaminated, and even when the marking portion is wound into the winder body, it is swollen by the marking tube, so that the marking portion can be easily confirmed. Further, the marking tube is held in advance so that the linear body passes through it, and when a marking command is generated, the marking tube moves together with the linear body while adhering to the marking portion of the linear body. Since the holding of the marking tube is released, the marking tube can be easily attached to the linear body that runs continuously.

(Example) An example of the present invention will be described in detail with reference to the drawings.
1 and 2 show a filament winding device 12 provided with a marking device 10 according to the present invention, and the filament winding device 12 has a guide sheave 16 provided on a traverser 14 to guide the filament. It consists of a winder body 20 on which the body 18 is wound. The winder body 20 is composed of a reel driving unit 22 and a reel supporting unit 26 that is connected to the reel driving unit 22 and supports the reel 24. In the illustrated embodiment, a plurality of winder bodies 20 are provided adjacent to each other and
When one winding machine main body 20 is fully wound, the next winding machine main body 20
It is designed to be wound around 20
Is provided so that it can be used in common to each winding machine main body.

The marking device 10 is shown in an enlarged manner in FIGS. 3 and 4, and the marking device 10 is provided immediately before the winder main body 12,
In the illustrated embodiment, it is provided immediately before the guide sheave 16 of the traverser 14, but it may be provided at another position. This marking device 10 supports a marking tube 28, through which a linear body 18 traveling toward a winder body 12 mounted on a frame 14A of a traverser 14 penetrates, so as not to move together with the linear body 18. A support member 30, a holding means 32 that normally holds the support member 30 in a position to support the marking tube 28, and a marking tube 18 for holding the support member 30 when the portion of the filament 18 to be marked reaches the support member 30. Release from the position that supports the marking tube
Retaining means 32 to allow 28 to move with striatum 18
Marking command means 34 (see FIGS. 7 and 8) for driving the. In the illustrated embodiment, the support member 30 comprises a lever arm 40 pivoted on a pin 38 secured to a bracket 36 mounted on the frame 14A. The marking tube 28 is made of a flexible material such as rubber or plastic.
Has a bent notch 28a through which the filament 18 passes, as shown in FIG. Therefore, the linear body 18 can penetrate into the marking tube 28 through this cut 28a, and the linear body 18 penetrated in this way can come off from the marking tube 28 because the cut 28a is bent. Absent. As shown in FIG. 6, the marking tube 28 includes a plurality of tube portions 28A, 28B which are fitted to each other.
The plurality of tubes 28A, 28B may be offset to have incisions 28a, 28b, respectively, through which the filament 18 passes. In this way, the striatum 18
Are preferable because they are more difficult to come off from the marking tube 28.

The holding means 32 is a stopper pin that engages with the lever arm 40.
42 and a stopper pin drive source 44 for moving the stopper pin 42 forward and backward with respect to the lever arm 40. In the illustrated embodiment, the stopper pin drive source 44 comprises a solenoid 46 mounted on the bracket 36.
Instead of 46, an air cylinder, an oil cylinder, a screw mechanism, a slider crank mechanism or the like may be used.

As shown in FIG. 7 and FIG. 8, the marking command means 34 drives one or more detectors 48 for detecting a defective portion of the linear body 18 and a stopper pin drive by a detection signal from these detectors 48. Source 44 Marking tube 28
And a signal processing circuit 50 that performs signal processing so as to drive in the backward direction immediately before reaching. The signal processing circuit 50 is
For example, a switch 52 that operates by a detection signal from a first detector 48A that is a detection electrode that detects peeling of the insulating layer (conductor exposure), a timer 54, and a relay 56 that is energized when the time of the timer 54 elapses. , Thyristor 60 which conducts in response to a detection signal from a second detector 48B which is a die for detecting bumps (bulges) of the linear body 18 and a first processing system 50A including
And the signal from this thyristor 60 is preset counter 62
And a second processing system 50B including relays 64, 66 which are energized via. The relays 56 and 64 energize the solenoid 46 which is the stopper pin drive source 4, and the relays 58 and 66 drive alarm devices 68 and 70 such as lamps, respectively.

Next, when the operation of the marking device is described, since the lever arm 40 supporting the marking tube 28 is normally restrained in the traveling direction of the linear body 18 by the engagement of the stopper pin 42, the lever tube 40 penetrates the marking tube 28. The linear body 18 that travels while traveling travels with the marking tube 28 left on the lever arm 40, and passes through the guide sheave 16 to wind the main body of the winder.
Winded up to 20. When any of the detectors 48 detects a defect in the striatum 18, the detection signal is sent to the signal processing circuit 50. The signal processing circuit 50 uses the timer 54 or the preset counter 62 to set the relay 5 immediately before the defective portion of the filament 18 reaches the marking tube 28 of the marking device 10.
Energize 6,58 or 64,66 to solenoid 46 and alarm 68
Or drive 70. Therefore, the alarm 68 or 70 is driven to inform the operator that the linear body 18 is defective, and the stopper pin 42 is retracted by the urging of the solenoid 46, whereby the lever arm 40 is released from the constraint and the marking tube is released. Since the support 28 is not supported, the linear body 18 is wound around the winding frame 24 of the winder body 20 through the guide sheave 16 together with the marking tube 28 at a position where the linear body 18 has a defective portion. Therefore, the operator can easily confirm the defective portion of the linear member 18 from the bulge of the winding frame 24.

The marking command means 34 may issue a marking command by a scale signal of the linear body 18. In this case, the marking command means 34 causes the stopper pin driving source 44 to move the measuring end portion of the linear body 18 to the marking tube 28 by a measuring instrument for measuring the linear body 18 and a standard signal from the measuring instrument. The signal processing circuit performs signal processing so as to drive in the backward direction immediately before reaching. In the above embodiment, the supporting member 30 is composed of the lever arm 40, and the holding means 32 is the lever arm 40.
Of the stopper tube 42 that moves back and forth with respect to the free end opposite to the marking tube supporting end of the holding means 32, but the holding means 32 moves the lever arm 40 between the marking tube engaging position and the disengaging position. It may be a linear drive source such as a cylinder directly connected to the lever arm 40 so as to move back and forth. In this case, since the lever arm 40 swings, the linear drive source is pivotally supported on the mounting bracket so as to allow this swinging motion.

Further, the support member 30 is not a lever arm, but an arm that moves linearly between the marking tube engagement position and the disengagement position, while the holding means 32 holds the arm in the engagement position or the engagement position. It may comprise a linear drive source that moves from the position to the disengaged position to release the marking tube 28 from its supported state.

In this way, the support member 30 and the holding means 32 normally support the marking tube 28 that normally penetrates in advance so that the filament 18 passes through, and remains attached to the marking portion of the filament 18 when a marking command is generated. It will be appreciated that various variants are possible if the holding of the marking tube 28 can be released so that it moves with the striatum.

(Effects of the Invention) According to the present invention, as described above, the marking tube is fitted into the filament to perform marking, so that the marking portion does not stain other filament portions, and the marking portion is caught. However, the marking tube is swollen by the marking tube even if it is wound inside the winder main body, so there is a practical advantage that the marking portion can be easily confirmed. Further, the marking tube is held in advance so that the linear body passes through it, and when a marking command is generated, the marking tube moves together with the linear body while adhering to the marking portion of the linear body. Since the holding of the marking tube is released, the marking tube can be easily attached to the linear body that runs continuously.
