層)과 전기의 만관보빈 상의 패키지가 서로 접촉하여 기계에 큰 고장이 생기는 위험성이 컸다.Conventionally, the bobbin support arm is rotated by 180 ° at the time of full attachment, attached to the winding machine of the thread, and the bobbin automatic changer which changes the position (abbreviated as change) between the full pipe bobbin and the empty bobbin supported at both ends of the arm. As a rule, doping of the manifold bobbin is carried out as soon as possible after the above-mentioned change. Therefore, if the manifold bobbin is left undoped for any reason, the four layers wound on the next bobbin supported by the arm arm in a relatively short time (

I) There was a high risk that the package on the full duct bobbin would come into contact with each other, resulting in a major failure of the machine.

SUMMARY OF THE INVENTION An object of the present invention is to provide a winding safety device that automatically triggers an emergency treatment such as stopping a thread to be supplied within a safe time if the manifold bobbin is not doped in order to prevent the above abnormal contact. have.

Referring to the drawings according to the embodiment (1) is the base of the winder including a bobbin automatic changer, (2) is a traverse cam roller supported and rotated on the base (1), the surface is inclined The traverse guide 3 is reciprocated in a direction perpendicular to the ground by the cam groove 2 '.

(4) is a friction roller attached to the Travacam roller (2), and rotates at the speed of winding the yarn (Y) supported on the same frame (1) as its circumferential speed.

On the other hand, (5) and (6) are upper and lower parallel guide rods in the bobbin automatic changer, and are fixed horizontally to the base in a direction perpendicular to the friction roller 4.

(7) is a movable table supported by the guide rods 5 and 6 and movable in the direction thereof, and (8) is a main shaft which is rotatably supported through the central portion of the movable table 7, By the driving device (not shown) installed at the rear side of the), it is configured to rotate half as shown by the A arrow at each change time.

(9) is the arm which fixed the center part in the front end part of the main shaft 8, The support shaft 10, 11 parallel to the main shaft 8 is fixed to the front of the both ends, and each supporting shaft 10 (11) ), The bobbin (12) or (13) is detachably mounted via a bobbin book equipped with a rotating material.

The movable table 7 is pushed to the right in the drawing by the driving device 16 using air pressure, and is supported on one side of the arm 9 which is not rotated except during the change of the bobbin (for example, 13) in contact with the friction roller (4).

In FIG. 1, 14 is a bobbin package wound around the bobbin 12 and changed and already in a doped position, and l is an empty bobbin supported at both ends of the arm 9. (13) and the gap between the two surfaces of the full package (14).

15 is a four-layered layer in which the yarn Y is swung and wound around the lower side of the friction roller 4 to be wound on the bobbin 13.

In the embodiment shown in FIG. 1, in the state shown in FIG. 1, when the unwound package 14 is left undoped, the four layers 15 formed on the next bobbin 13 have the above-described spacing (l). In order to prevent contact with the universal package 14 in advance at a thickness equivalent to the limit of a time shorter than a predetermined time until the contact between both at a predetermined time point after the change is started. If a time actuator such as a timer is provided for the bobbin automatic changer and the doping is not performed within the above-mentioned time period, the supply of the yarn to the winder is automatically stopped by the time-out operation such as the timer described above, or If an automatic doping device is provided, it is necessary to make an urgent action such as operating the device again.If the doping is smooth within the same time, the timer action Upon completion of the doping, it is automatically released and can be adjusted for the next change.

Next, the electric circuit related to this winding safety device provided for the above-mentioned bobbin automatic change device will be described with respect to the operation of the copper converter, and the circuit for change (1a-2a) and the circuit for detachable bobbin will be described. The limit switches LS ₁ and the copper LS ₂ are respectively mounted on (1b-2b) and are attached to the cam shafts 17 connected to the main shaft 8 of the bobbin automatic changer. Each circuit is largely pressed, and it is almost press-bonded to the cam surface to form a circuit, but is engaged with the short elements 18 'and 19' of the cam surface each time during each change.

Further, the time when the limit switch LS ₁ is disconnected for a short time is just before the change is finished, and the time when the limit switch LS ₂ is disconnected is slightly earlier than the time when the former is disconnected. The relay contact CR ₁ is energized when the bobbin 12 is wound on the winding side, as shown in FIG. 3, and starts the change, and CR _{11 is} connected to the circuits 1a-2a. It is a snowy secondary relay.

In circuit (1b-2b), (BS ₂₁ ) is the button switch (BS ₂₂ ) pressed when inserting the empty bobbin on the axis, and the button switch (CR ₂₁ ) is pressed when the manifold bobbin is easily removed from the axis. It is an auxiliary relay of the same circuit.

(L) denotes a lamp TDR ₃₁ which informs the doping of the full pipe bobbin is a time-acting body such as a timer, which is the point of the present invention, and this time-time is set as follows.

As shown in FIG. 3, the change start command is issued by a detector (not shown) which detects the bobbin 12 in the winding as the outer diameter or the like when the bobbin 12 in the winding is full.

The relay contact CR ₁ is energized. In particular, at the time of the previous doping (limit switch LS ₂ constitutes a circuit), after loosening the full pipe bobbin, the hollow bobbin 13 is inserted into the shaft 11 instead, and the button switch BS ₂₁ Since the auxiliary relay CR ₂₁ is energized because it is depressed, the circuits 1c-3c are in the state of powering off at the start of the change.

In this way, when the change is started and progresses, the limit switch LS ₂ is first disconnected at a time before the change is completed, and the circuit 1c-3c is energized by disconnecting the auxiliary relay CR ₂₁ . (L) is turned on and foresight of the operator to dope the full pipe bobbin (12).

On the other hand, the timer TDR ₃₁ starts the time limit operation because the relay contact CR ₁₁ is energized.

In this case, the time limit of the timer TDR ₃₁ is determined on the next bobbin 13 which continues winding when the unwound package 14 to be doped at the time of starting the above-described time action is left unchanged for some reason. The thread layer 15 formed in the chamber is set at a time slightly shorter than the time required until the yarn layer package 14 comes into contact with the package.

Limit switch doeyeo unit cells while the limit switch (LS ₁₎ immediately before a slightly later change ends (LS ₂₎ a minute, the secondary relay (CR ₁₁₎ is the same relay contact of the unit cell doeyeo circuit (3d-4d) (CR ₁₁ ), But the timer TDR ₃₁ has no effect since the self-supporting contact TDR _{31 of the} timer is energized.

Therefore, when doping is not performed within the above-described set time, the timer TDR ₃₁ performs timed operation within the set range, and as a result of this operation, emergency processing such as stopping supply of the seal is automatically started. In general, however, it is almost impossible that doping is not performed on a full package, and in general, doping is usually performed within a prescribed time.

Here, when explaining the operation of the circuit in this case, the worker who has learned to dope with the point of the lamp (L), etc. first press the button switch (BS ₂₂ ) to complete the bobbin book, and pull out the full pipe bobbin from the axis, empty bobbin Press the bobbin switch (BS ₂₁ ) to operate the bobbin book, and hold the empty bobbin on the shaft. At the time of the doping, the limit switch LS ₂ is energized so that the button switch BS ₂₁ is energized so that the circuit 1c-3c disconnects the circuit at the time of completion of the doping so that the lamp L goes off. At the same time, the timer TDR ₃₁ is timed out and is ready for the next change.

On the other hand, in the circuits 1a-2a, the relay contact CR ₂₁ is energized and is in a state of waiting for the next change start signal. After that, if the work proceeds normally, the timer TDR ₃₁ does not trigger an emergency action as its timed operation, but prevents the timed action, freezing and readjustment proactively.

In addition, in the above embodiment, the timer is used as a time-operating body to continue or stop the frame operation with or without doping of the multi-package package. Alternatively, when the winding operation is performed after the change by the time set for the timer, For example, a change in the bobbin diameter due to the winding of the thread, the displacement of the arm supporting the bobbin check, or the winding of the friction roller in case of the winding machine of the type in which the friction roller side moves when the arm is in the correct position is detected. If a switch or the like is provided so that doping of the wound package is not performed within the set time until the switch is activated, an electrical time control circuit may be configured to stop supply of the seal as described above. The electrical control circuit may also be replaced with a control circuit using a fluid pressure. In addition, the button switch BS _{21 in the} above embodiment operates when the empty bobbin is held in the bobbin chunk, or as a means for detecting that the dopant is not doped as in the present invention. In this case, the doping action of the pan-package can be performed by an operator or by mechanical automation.

As described above, in the present invention, when the bobbin bobbin after the change is left undoped, the bobbin package on the bobbin and the four layers of the next winding are in contact with each other. The main point is to establish a time-acting body that operates within a safe time until this abnormal condition occurs, and automatically triggers an urgent process such as stopping a thread to be supplied to the winder. In the case of performing, it is readjusted with respect to the next change, and as a winding safety device that achieves the object of the present invention, the effect is particularly great for the winding machine of continuous operation, and further, the effect is achieved without any hassle.
