BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a twisted wire device.

[0002]

2. Description of the Related Art If a winding start end of a twisted wire of a full bobbin is connected to a winding end end of a twisted wire of another full bobbin, it is possible to continuously supply the twisted wire. In order to do this, it is necessary that the winding start end of the twisted wire is exposed from the winding layer of the full bobbin by the length required for connection. Therefore, in the conventional twisting wire device, one of the bobbin attaching / detaching devices provided on both sides of the cradle so as to face each other is provided with a twisted wire winding start end holding plate facing one flange of the bobbin, and a holding plate is provided. When the bobbin is attached / detached at the same time, it is pressed / separated at the same time.When mounting an empty bobbin mounted on the trolley on the upper limit lifter to the cradle, the twisted wire grip below the one flange of the bobbin and the holding plate in the separated state. It is grasped by the grasping member of the cutting device and traverses from the start position to the full bobbin that descends.
The twisted wire extending to the roller was sandwiched between the flange and the holding plate, and this was cut by operating the cutting member of the twisted wire gripping and cutting device.

In order to wind the twisted wire around the bobbin, it is necessary to rotate the bobbin and simultaneously move the twisted wire sandwiched between the flange and the holding plate over the flange and transfer it to the bobbin cylinder. Since the peripheral surface is smooth, the stranded wire does not slide on the rotating flange peripheral surface and move to the bobbin cylinder as it is. Therefore, conventionally, a plurality of, for example, 12 claws slightly protruding from the peripheral surface of the flange are provided at equal intervals.
The rotation of the bobbin causes the twisted wire to be hooked on one of the claws to prevent slippage, so that the wire can be transferred to the bobbin barrel.

Further, in the conventional twisting device, the traverse
The roller is provided with a moving body that reciprocates the roller from one end to the other end along the bobbin cylinder, and a rotating shaft that moves the moving body. The rotating shaft is a power transmission means by a bobbin rotating motor. It is rotated in one direction via the
When the roller reaches each end of the bobbin cylinder, the direction of movement is changed so that the roller can reciprocate.

[0005]

In the conventional twisting device,
The length of the winding start end side of the twisted wire exposed from the winding layer of the full-winding bobbin has a limit because the twisted wire is linearly sandwiched between the flange of the bobbin and the holding plate. By the way, depending on the type of twisted wire, the length of the winding start end side of the twisted wire extending from the winding layer of the full winding bobbin depends on the ease of connection with the winding end end of the twisted wire of another full winding bobbin. Due to the relationship, it is often preferable to use a longer length. For that purpose, an annular winding groove is provided on the outer surface of the flange, and by rotating the bobbin,
All you have to do is to wind the twisted wire in the required length. However, if there are as many as 12 claws on the flange as in the conventional case, the stranded wire will move from the outside of the flange to the bobbin cylinder with 1/12 rotation of the bobbin, so there is no point in providing a winding groove. We cannot meet the above demands.

Further, the length of the twisted wire to be wound on the bobbin is predetermined, but when the twisted wire is wound on the bobbin, it becomes the above-mentioned fixed size almost in the middle of the length of the bobbin barrel. When the traverse roller is in the forward stroke, it once moves from the intermediate position to the end position, then returns from there to the start position, and when the traverse roller is in the backward stroke, it moves from the intermediate position to the start position. Although returning, during that time, the twisted wire is forced to be wound around the bobbin cylinder at a normal pitch, which causes a problem that a wasteful winding length of the twisted wire and a wasteful winding time occur.

One of the objects of the present invention is to provide a twisting device capable of obtaining a desired length of a winding start end side of a twisted wire extending from a winding layer of a full bobbin. In addition, another one of the objects of the present invention is to use wasteful winding length of the twisted wire,
It is an object of the present invention to provide a twisted wire device that can reduce wasteful winding time as much as possible.

[0010]

According to the first aspect of the present invention, there is provided a twisting wire device for guiding a twisted wire to a bobbin cylinder, and a traverse roller which supports the traverse roller and extends along the bobbin cylinder from one end to the other end. In a twisted wire device including a moving body that reciprocates and a rotating shaft that moves the moving body, a first electromagnetic clutch and a second electromagnetic clutch that are attached to both ends of the rotating shaft, and rotation via the first electromagnetic clutch. A first power transmission means connected to one end of the shaft and transmitting unidirectional rotational power of the bobbin rotation motor; and a separate reversible motor connected to the other end of the rotation shaft via a second electromagnetic clutch. Second power transmission means for transmitting rotational power in both forward and reverse directions, first detection means for detecting arrival of the traverse roller at the start position, and the traverse roller inward at a predetermined distance from the start position. It is provided with a second detection means for detecting the movement and an annular winding groove provided on the outer surface of the flange of the bobbin on the side of the start position, and when the rotary shaft is connected to the second power transmission means, the first power transmission means is provided. It is designed to rotate faster than when the power transmission means is connected, and the winding start end side of the twisted wire to be wound on the bobbin is hung on the traverse roller at the start position and stopped outside the flange. , The first electromagnetic clutch and the second electromagnetic clutch are turned off, the traverse roller is held at the start position, and the winding start end side of the twisted wire to be wound on the bobbin is fixed to one flange of the bobbin, and then the bobbin rotates. The stranded wire is wound in the winding groove by operating the motor for use and rotating the bobbin. When the second electromagnetic clutch is turned on and the reversible motor is rotated normally after the length required for connection is accumulated, the rotating shaft connected to the second power transmission means rotates normally, and the moving body is the end point of the traverse roller. Move at a high speed in the direction of the position. As a result, tension is applied to the twisted wire in the moving direction of the traverse roller from the winding groove, so that the twisted wire is transferred to the bobbin barrel side without slipping over the peripheral surface of the bobbin flange. Then, when the moving body reaches the position of the second detecting means, it is detected that the traverse roller has reached from the start position to the position where the twisted wire can be passed over the flange, and the reversible motor is rotated in reverse.
By the reverse rotation of the rotary shaft, the moving body moves in the opposite direction, and when it reaches the position of the first detecting means, it is detected that the traverse roller has reached the start position again, and the second electromagnetic clutch is turned off. At the same time, the first electromagnetic clutch is turned on. When the first electromagnetic clutch is turned on, the rotary shaft connected to the first power transmission means rotates in the normal direction because its power source is the bobbin rotation motor as in the conventional case. After that, the reciprocating motion of the traverse roller by the moving body winds the twisted wire of a predetermined length around the bobbin.

The twisted wire device according to a second aspect of the present invention is, in addition to the structure of the first aspect of the present invention, further comprises a fixed-size winding detection means for detecting that the twisted wire has been wound around the bobbin for a predetermined length. Since the traverse roller moving direction discriminating means for discriminating the moving direction of the traverse roller at the time of this detection is provided, it is possible to confirm that the stranded wire has been wound on the bobbin by a predetermined length by the constant size winding detecting means. At the same time, the traverse roller movement direction determination means determines the movement direction of the traverse roller in the middle of the length of the bobbin cylinder,
If the traverse roller is heading towards the end position,
The first electromagnetic clutch is turned off, the second electromagnetic clutch is turned on, the reversible motor is reversely rotated to reversely rotate the rotary shaft, and the moving direction of the moving body is forcibly changed to be faster than the normal winding. Return with. When the traverse roller is moving toward the start position, the reversible motor is rotated in the normal direction to return the moving body to the normal state at a speed faster than that during the normal winding. The first detecting means detects that the traverse roller has reached the start position,
As a result, the reversible motor is stopped to stop the moving body, and the bobbin rotating motor is stopped to stop the rotation of the bobbin.

Next, the operation of the twisting device will be described with reference to FIGS.
Will be sequentially described with reference to. First, the twisted wire (T) is hung between the twisted wire winding start end holding plate (40) and the disc (36) on the bobbin (14) side, which are at the separated positions shown by the chain line in FIG. As the holding plate (40) moves to the solid line position as the bobbin (14) is mounted on the cradle (20), the twisted wire (T) is held between the two. This twisted wire (T) is pushed by the annular protrusion (41a) of the elastic layer (41) and comes to the position of the winding groove (16). Therefore, the first electromagnetic clutch (6) and the second electromagnetic clutch
Turn off (7), hold the traverse roller (3) in the start position and start the bobbin rotation motor (8).
When the bobbin (14) is rotated, the twisted wire (T) is wound in the winding groove (16) (see FIG. 3). When the timer detects that the length required for connection has been accumulated, the second electromagnetic clutch (7) is given an ON signal, and the reversible motor (10) is rotated in the forward direction to connect to the second power transmission means (11). The rotation axis (5) is rotated forward,
The moving body (4) moves at a high speed in the direction of the end position of the traverse roller (3). As a result, tension is applied to the twisted wire (T) in the moving direction of the traverse roller (3) from the winding groove (16), so that the twisted wire (T) is attached to the flange (15) of the bobbin (14). It is moved to the bobbin cylinder (1) side without slipping over the circumference of the bobbin. Then, when the moving body (4) reaches the position of the second detecting means (13), it is detected that the traverse roller (3) has reached from the starting position to a position where the twisted wire (T) can be passed over the flange. Then, a signal for reversing this is given to the reversible motor (10) (see FIG. 4). By the reverse rotation of the rotary shaft (5), the moving body (4) moves in the opposite direction, and when it reaches the position of the first detecting means (12), the traverse roller (3) has reached the start position again. Is detected and an off signal is given to the second electromagnetic clutch (7) and an on signal is given to the first electromagnetic clutch (6) (see FIG. 5). During this reciprocating movement of the traverse roller (3), the traversing roller (3) moves fast, so the twisted wire (T) is
It can be wound around (1). The first part of the twisted wire (T) beyond the flange (15) extends diagonally slightly inward from the end of the bobbin barrel (1), but when the traverse roller (3) returns, it is rough. Since the wound stranded wire (T) is pulled toward the flange side, when the traverse roller (3) is at the start position, the slanted portion is straight along the inner surface of the flange (15). When the first electromagnetic clutch (6) is turned on, the rotary shaft connected to the first power transmission means (9)
(5) is a bobbin rotation motor whose power source is the same as before.
Since it is (8), it rotates forward. After that, the reciprocating movement of the traverse roller (3) by the moving body (4) causes the twisted wire (T) of a predetermined length to be wound around the bobbin (14) (see FIG. 6). During this period, the first detecting means (12) and the second detecting means (13) are not operated.

Then, the constant size winding detecting means (56) detects that the twisted wire (T) has been wound around the bobbin (14) for a predetermined length, and at the same time, the traverse roller moving direction determining means.
By (17), the moving direction of the traverse roller (3) in the middle of the length of the bobbin cylinder (1) is determined. The constant-size winding detecting means (56) shown in FIG. 1 is in contact with the untwisted wire (X) and rotates with the forward movement of the wire (57) and the measuring pulse proximity switch desired for this. (56) is used.
When the traverse roller (3) is moving toward the end position as shown in Fig. 7, the reflector (50) is a reflector type photoelectric switch (1
Since it is opposed to 7), its moving direction is detected and an off signal is given to the first electromagnetic clutch (6) and an on signal is given to the second electromagnetic clutch (7).
A reverse rotation signal is given to (10) (see FIG. 7). Then the rotation axis
(5) rotates in the reverse direction, forcibly changes the moving direction of the moving body (4) and restores it at a faster speed than during normal winding. Contrary to Fig. 7, when the traverse roller (3) is moving toward the start position, the lever (48) is tilted to the right, so if the light of the photoelectric switch (17) hits the reflector (50). Absent. Therefore, the moving direction is detected by this, and the reversible motor (1
A forward rotation signal is given to 0) and the moving body (4) is returned in a normal state at a speed faster than that during normal winding. At this time
When the first detection means (12) in a movable state detects that the traverse roller (3) has reached the start position, and gives a stop signal to the reversible motor (10), the moving body ( 4) stops. At the same time bobbin rotation motor
When the stop signal is given to (8), the bobbin (14) stops rotating. The reflection type photoelectric switch (17) and the reflection plate (50) may be arranged on the opposite side of this embodiment.

[0022]

According to the twisted wire device of the first aspect of the invention, the twisted wire, which is hooked on the traverse roller at the start position and whose winding start end is stopped outside the flange of the bobbin, has a flange without a claw. Since it can be transferred to the bobbin barrel side without slipping the peripheral surface, the length required for connection can be wound and stored in this by providing an annular winding groove on the outside of the flange.

According to the twisted wire device of the second aspect of the invention, when the constant-size winding is completed in the middle of the length of the bobbin cylinder, regardless of the moving direction of the traverse roller, Since the traverse roller can be immediately returned to the start position at a speed higher than that at the time of usual winding stop, it is possible to reduce the wasteful winding length and the wasteful winding time as much as possible.
