1 is a perspective view of a wire winding device according to an embodiment of the present invention, and FIGS. 2 to 4 are perspective, side, and plan views of main components of a wire winding device, respectively, in an embodiment of the present invention.

As shown, the wire winding device according to an embodiment of the present invention is a device for moving and winding to a standardized second bobbin 20 for the progress of a specific process for using molybdenum wire wound on the first bobbin 10 As a guide, control and measure the transfer of the wire (W) between the first cradle 110 and the second cradle 120 including the first bobbin 10 and the second bobbin 20, respectively For the encoder 140, the wire diameter measuring member 150, the wire clamp 160, the traverse 130 is sequentially disposed on the base top (100A).

The wire winding device according to the embodiment of the present invention including such a main configuration is smooth from the first bobbin 10 purchased on the market to the second bobbin 20 made in accordance with the manufacturing process for processing the wire W. In addition to being able to move, the wire diameter of the wire can be measured in real time to exclude wires that are not suitable for the process or bobbins winding the wire from the device.

Hereinafter, a wire winding apparatus according to an embodiment of the present invention will be described in more detail with respect to each of the above components.

The first cradle 110 is installed on the upper surface of the device base 100A and serves to rotatably mount a first bobbin 10 wound with a commercially available raw material wire. To this end, the first cradle 110 includes a first rotating shaft 111 rotatably supporting the first bobbin 10. It is preferable that a torque controller is installed on the first rotating shaft 111 to properly maintain tension when the wire is released from the first bobbin 10.

The second cradle 120 is installed at a position spaced forward from the first cradle 110 on the upper surface of the device base 100A and mounts the second bobbin 20 by the second rotating shaft 121. In the case of the second rotating shaft 121, the wire wound around the first bobbin 10 is wound while rotating the second bobbin 20 mounted by the driving force of the first motor 122.

The traverse 130 is installed on the rear side of the first cradle 110 and serves to guide the wire evenly around the second bobbin 20. To this end, the traverse 130 includes a left-right moving body 133 that reciprocates in a sliding motion in the left-right direction from the support 131, and a second motor 132 that provides driving force to the left-right moving body 133. do. And the moving body 133 is provided with a pair of guide rollers (133a) for guiding the wire. When the traverse 130 provided with the moving body 133 in the left-right direction is provided, the wire is evenly wound in the left-right direction with respect to the second bobbin 20 so as not to be biased to either side. In the case of the left and right moving bodies 133, it is suitable to move with a width of about 10 cm.

Furthermore, the traverse 130 may be configured such that the support 131 is movable in the front-rear direction. To this end, as shown in FIG. 2, the front and rear rails 134 are installed on the upper surface of the traverse base 135, and the support 131 supporting the left and right moving bodies 133 is mounted on the front and rear rails 134. It can be made to be movable in the front-rear direction.

Here, as shown in the traverse 130, the second rotating shaft 121 supporting the second bobbin 20 and its components in the left and right directions to evenly wind the wire in the left and right directions relative to the second bobbin 20. It is easy to think of a configuration in which the second bobbin 20 is moved by reciprocating displacement, but in this case, the configuration is much more complicated and difficult to design due to the need to change the system to which the driving force of the first motor 122 is transmitted. There is this. However, in the embodiment of the present invention, in the case of the traverse 130 installed separately from the second cradle 120, there is an advantage of simply applying and installing in a form similar to the LM guide.

The encoder 140 is installed between the first cradle 110 and the second cradle 120, but is relatively installed near the second cradle 120. The encoder 140 includes an encoder body 141 supported on the upper surface of the device base 100A as shown in FIGS. 2 and 3, a roller-type contact sensor 142 installed on one surface of the encoder body 141, and a wire. It consists of a sensor 144.

The roller-type contact sensor 142 of the encoder 140 rotates by obtaining a driving force by contact with the wire being transferred. Accordingly, it is possible to calculate the length and weight of the wire transferred from the first bobbin 10 to the second bobbin 20 based on the number of revolutions of the roller-type contact sensor 142. Such a roller-type contact sensor 142 has an advantage of being able to measure the transport length of the wire as well as serving as a general guide roller for guiding and guiding the wire. On the other hand, in the vicinity (bottom) of the roller-type contact sensor 142, a pair of auxiliary rollers 143 that help the wire to stably contact the roller-type contact sensor 142 while contacting the wire from the opposite side around the wire. Is installed.

On the other hand, the wire detection sensor 144 of the encoder 140, the wire passes from among the points biased to the rear side of the first cradle 110 from the point where the roller-type contact sensor 142 is installed on one surface of the encoder body 141. It is installed at the branch. The wire detection sensor 144 normally detects the wire in real time and transmits the detection signal to the controller. The wire detection sensor 144 may be installed as long as it is of a type capable of detecting a wire existing in the detection area, such as an ultrasonic sensor. When the wire detection sensor 144 is provided as described above, the wire is normally sensed by the wire detection sensor 144, and when the wire disappears from the detection area and cannot be detected, the controller is disconnected or exhausted (first bobbin 10). It is possible to respond as if it were considered as the amount that was wound on the machine. Here, in the encoder body 141, a pair of horizontal guide rollers 145a and vertical guide rollers 145b are installed adjacent to each other in order to guide the wire more precisely so that the wire passes through the detection area of the wire detection sensor 144 accurately. do.

The wire clamp 160 works in conjunction with the wire detection sensor 144 to quickly hold the wire at the moment the wire detection sensor 144 does not detect the wire normally detected. This serves to prevent the wire from being unwound from the second bobbin 20. To this end, the wire clamp 160 is installed at a position closer to the second cradle 120 than the wire sense sensor 144 to be disposed between the wire sense sensor 144 and the second cradle 120. The wire clamp 160 is installed and installed on the device base 100A as shown in FIGS. 7A and 7B and a support panel 161 formed with a wire through hole 161a to penetrate a wire transferred to the upper end, and the support panel It consists of a pair of cylinders 162 and contact pieces 163 installed on the (161). The cylinder 162 is installed in a form in which the tip portion is gathered toward the wire through hole 161a from the left side and the post of the support panel 161, as shown in the drawing, but is installed in an upward diagonal direction. Thus, when the pair of cylinders 162 are not installed horizontally while being symmetrical at both sides, and the tip is installed diagonally upward so as to face the wire through hole 161a, it is connected to the rear end of the cylinder 162 while reducing the left and right widths. It is advantageous to arrange the pneumatic line to be downward, so that it does not protrude from side to side.

On the other hand, the pair of contact pieces 163 are respectively coupled to the distal end of the arm 162a of the cylinder 162 to hold the wire while facing the left side and the post when advancing the arm 162a. It is preferable that a friction material 164 such as silicon or rubber is additionally installed on the opposite surface of the contact piece 163 to stably hold the wire.

The wire diameter measuring member 150 serves to measure the wire diameter of the wire being transported by laser irradiation in the X-axis direction and the Y-axis direction in real time. The wire diameter measuring member 150 may be installed between the first cradle 110 and the second cradle 120, and is preferably disposed on the rear side of the wire clamp 160. The wire diameter measurement member 150 includes a support 151, a sensor mounting table 152, an X-direction laser sensor 153a, and a Y-direction laser sensor 153b as shown in FIGS. 5 and 6.

The support 151 of the wire diameter measuring member 150 is a first support portion 161a having a first triangular groove 161d and a second triangular groove 161e for guiding the wire to be transported in a seated state, respectively. And a second support part 161b, wherein the first support part 161a and the second support part 161b are spaced apart from each other with a space 161c.

The sensor mounting table 152 of the wire diameter measuring member 150 is installed in a form surrounding the space 161c between the first support portion 161a and the second support portion 161b of the support 151. The sensor mounting table 152 is composed of a plurality of divided surfaces having an octagonal shape on the inner surface so that the X-direction laser sensor 153a and the Y-direction laser sensor 153b can be installed on the inner surface thereof, and the upper part of the wire It is formed in a unique structure with an opening 152a for entry and exit.

The X-direction laser sensor 153a and the Y-direction laser sensor 153b of the wire diameter measuring member 150 are installed on the inner surface of the sensor mounting table 152 as shown in FIG. 6 and are perpendicular to each other at each installation point. The wire diameter of the wire located in the separation space 161c between the first support portion 161a and the second support portion 161b is measured in real time by irradiating a laser in the axial direction and the Y-axis direction. The X-direction laser sensor 153a and the Y-direction laser sensor 153b are respectively installed on two divided surfaces formed orthogonally to each other among the inner surfaces formed in the octagonal shape in the sensor mounting table 152, and opposite from each other. Absorbing plates are installed on the surfaces to absorb the laser. For this, the X-direction laser among the divided surfaces of the octagonal inner surface is not exposed so that the irradiated laser does not interfere with the support 151 in the middle or flows out through the opening 152a formed on the top of the sensor mount 152. The sensor 153a and the Y-direction laser sensor 153b are preferably installed on a diagonal surface rather than a vertical surface or a horizontal surface. For example, in the drawing, the X-direction laser sensor 153a and the Y-direction laser sensor 153b may be installed on diagonal surfaces located on both sides of the lower horizontal plane among the inner surfaces.

When the wire diameter measuring member 150 is provided as described above, it is possible to simultaneously measure the wire diameter of the wire to be transported in the X-axis direction and the Y-axis direction, and at least one of the X-axis direction measurement value and the Y-axis direction measurement value is excessive due to a deviation from the setting range If it is too thick or thin, the controller will immediately stop the transfer of the wire. Then, the operator can exclude the corresponding wire through inspection, and for this, active measures such as replacing the first bobbin 10 and the second bobbin 20 with new ones may be taken.

Although the preferred embodiments of the present invention have been described above, the present invention can use various changes, modifications, and equivalents. It is clear that the present invention can be equally applied by appropriately modifying the above embodiments.
