Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding bobbin for feeding a wire wound in a winding space of a bobbin so that the feeding direction of the wire is always perpendicular to a feeding surface. The present invention relates to a wire feeding direction constant device capable of transmitting a wire.

[0002]

2. Description of the Related Art Conventionally, when a wire w is fed from this type of feeding bobbin 11, the feeding point of the wire w reciprocates in parallel along the surface of the feeding bobbin 11 in accordance with the feeding of the wire w. . Therefore, when the position of the sheave 12 that initially guides and supports the fed wire w is set to a position close to the feeding bobbin 11 as shown in FIG. 5, the wire w is moved in accordance with the feeding motion of the wire w. Will swing right and left.

In particular, the feeding point of the wire w is the feeding bobbin 1
As the wire w moves from the center to the end of the winding surface, the wire w becomes gradually sharper in the direction in which the wire w is drawn out, and the wire w to be fed is entangled with the adjacent wire wound. In some cases, the smoothing of the feeding operation may be hindered by being stuck.

[0004] In order to solve the problem, the wire w may be fed in a direction perpendicular to the feeding surface as much as possible. For this purpose, the position of the sheave 12 that initially guides and supports the unwound wire w may be set at an infinite position from the unwinding bobbin 11, but in reality, as shown in FIG. It will be set as far away as possible.

[0005] In this case, there is an unavoidable increase in the size of the structure, and there is a disadvantage that a large installation space is required for installation.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a wire feeding point which reciprocates in parallel along the surface of a feeding bobbin, and a position of a sheave for initially guiding and supporting a wire fed from the wire feeding point. By moving the wire fed from the wire feeding point synchronously in parallel with each other, the feeding direction of the wire fed from the wire feeding point can always be perpendicular to the feeding bobbin, whereby the distance between the sheave and the feeding bobbin can be reduced. Accordingly, it is an object of the present invention to obtain a wire feeding direction constant apparatus which can contribute to downsizing of a structure and narrowing of an installation space.

Drive times It reduced the number, or, is intended to provide a wire feeding direction constant device from feeding bobbin and a drive device which is set to stop.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below in detail with reference to the drawings. First, FIGS. 1 and 2 show one embodiment of the present invention. A feeding bobbin 1 on which a wire w is wound around a winding space of a bobbin is rotatably mounted on a mounting shaft 2 thereof. . A reciprocating device (traverse device) A that can reciprocate at a required interval as shown in Japanese Patent Publication No. 47-12901 in parallel with the feeding bobbin mounting shaft 2 at a required interval.
The driving rotary shaft 3 is provided.

The reciprocating device A is provided with a penetrating portion 4 through which a wire w is inserted at a required portion thereof, and a mounting substrate 5 projecting forward and backward is integrally formed near the penetrating portion 4. Is provided.

An inclination detector 6a is installed on the mounting board 5 at a position in a direction perpendicular to the penetrating portion 4 of the reciprocating device A at a rear portion facing the feeding bobbin mounting shaft 2. A sheave 7 is rotatably provided at a front portion of the position sandwiching the through portion 4.

The tilt detector 6a has a pulley-shaped rotating wheel, and a wire w transmitted through the rotating wheel is abnormal with respect to a normal state where the wire w is transmitted in a normal direction. When the wire is sent in a desired direction, the pulley is inclined by the tension in the sending direction of the wire w.

The tilt detector 6a is electrically connected to the driving device 8 of the driving rotary shaft 3 of the reciprocating device A. When the tilt detector 6a tilts, a signal generated during the tilting is used. The drive rotation speed of the drive device 8 is reduced,
Alternatively, it is set to stop.

FIGS. 3 and 4 show another embodiment, in which two contact sensors 6b, 6b are installed instead of the tilt detector 6a of the above-mentioned embodiment. The contact sensors 6b, 6b are arranged side by side at a slight interval at a portion in a direction orthogonal to the through portion 4 of the reciprocating device A.

The contact sensors 6b, 6b are electrically connected to the driving device 8 of the driving rotary shaft 3 of the reciprocating device A. When the contact sensors come into contact with each other, a signal generated during the contact is used. The drive rotation speed of the drive device 8 is set to be reduced or stopped.

In each of the above-mentioned configurations, prior to the start of operation, the reciprocating movement width of the reciprocating device A is made to correspond to the wire winding width of the feeding bobbin 1 and the wire w fed from the feeding bobbin 1 is adjusted. Synchronizing the pitch speed at which the reciprocating device A moves in the same direction with the pitch speed at which the reciprocating device A is released and moved along the feeding bobbin shaft surface,
The wire w is connected to the tilt detector 6a or the contact sensor 6
b, 6b through the penetrating portion 4 to the contact point of the sheave 7 in a straight line, and is initially transmitted through the circular surface of the sheave 7 in the direction of the fixed sheave 9 fixed at a predetermined position. Set.

The feeding operation of the wire w is started from the above initial setting. In the course of the operation, if the pitch speed of the feeding bobbin 1 and the moving speed of the reciprocating device A match, as shown in FIG. 1 or FIG. It is fed at a right angle to the feeding bobbin 1 from the feeding point, and is drawn straight through the inclination detector 6a or from between the contact sensors 6b, 6b to the contact point of the sheave 7 through the penetrating portion 4.

In the course of the above-described feeding operation, the wire w to be fed is entangled or hooked on the adjacent wire being wound, and the timing of the feeding operation is shifted, so that the movement of the reciprocating device A is performed. When a delay occurs with respect to the speed, as shown in FIG. 2 or FIG. 4, the wire w is fed from the feeding point of the feeding bobbin 1 at a right angle to the feeding bobbin 1. The state is shifted to a state where the reciprocating device A drags the user.

That is, when the reciprocating device A is moving to the left, the wire w is tilted to the left in the case of the tilt detector 6a and the contact sensor 6b , 6b contact the sensor on the right side, and conversely, while the reciprocating device A is moving rightward, the tilt detector 6a tilts it rightward, , The contact sensors 6b, 6b make contact with the sensor on the left side.

As described above, when the wire w tilts the tilt detector 6a in any direction or touches any of the contact sensors 6b, 6b, a signal is generated during that time. The signal is transmitted to the driving device 8 of the driving rotary shaft 3 of the reciprocating device A, during which the driving speed of the driving device 8 is reduced or stopped.

The above operation lowers the driving rotation speed,
Alternatively, the stopped driving device 8 reduces or stops the moving speed of the reciprocating device A during that time. Thereby, it waits momentarily until the transmission delay of the wire w is recovered. Immediately after that, when the wire w releases the tilt state of the tilt detector 6a or the contact state with the contact sensors 6b, 6b, the wire w is restored to the initial normal operation.
Continue transmission of. Thereafter, the same operation is performed, and the wire is fed so as to always follow the feeding direction of the wire fed to the feeding bobbin at right angles to the feeding surface.

[0021]

As apparent from the above description, according to the present invention, the wire feeding point reciprocating in parallel along the surface of the feeding bobbin and the wire fed from the wire feeding point are first guided and supported. Since the position of the sheave and the position of the sheave can be moved synchronously in parallel with each other, the feeding direction of the wire fed from the wire feeding point can always be perpendicular to the feeding bobbin, so that even when the wire is entangled or caught, Immediately, the transmission line is restored smoothly.

Further, the distance between the feeding bobbin and the sheave can be reduced, thereby contributing to downsizing of the structure and the installation space.
