Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention can easily hold various wire drums of different sizes (different diameters) and freely control their rotation, mainly in factories. , relates to an electric wire winding and supply device.

[Conventional technology]

Conventional apparatuses having the functions of winding and supplying electric wires (holding electric wires to be wound up) include those having a jack cylinder part buried underground, and those having a gate type.

[Problem to be solved by the invention]

However, since electric wire drums come in various sizes, from small diameter drums to large diameter drums, conventional devices have difficulty controlling the rotation of the electric wire drums as they move up and down (for example, in devices that drive the center of the drum, it is difficult to control the rotation of each drum. It is necessary to press and fix the drive part to the center of the drum, and control of its rotation becomes more difficult as the diameter of the drum increases.Also, in devices that drive the drum's outer periphery, the position of the drive part must be changed each time the drum diameter changes. ),
In addition, it is unavoidable that the mechanism becomes complicated (for example, the entire device becomes large-scale, and the various mechanisms necessary to attach, change, and move the drive unit for each drum become complicated).

The present invention was made to eliminate these drawbacks of conventional devices.The driving (brake) roller can be left in a fixed position, and the wire drum can be held by simply adjusting the vertical movement of the lifting mechanism (screw jack). However, it is an object of the present invention to provide an electric wire winding and supplying device which can control the rotation of the drum, has a simple structure, and can easily install and relocate the line using only anchor bolts.

[Means to solve the problem]

That is, the electric wire winding supply device of the present invention that overcomes the above problems includes a base plate, a driving roller that is fixedly installed on the base plate and acts in contact with the outer circumference of the electric wire drum, and the base plate. A pair of left and right screw jacks are respectively installed in front of both sides of the driving roller in a state of inclination in the direction opposite to the roller side, and a pair of screw jacks are installed inside each of the screw jacks so as to move up and down by the jacking action. and a V-shaped cross-section bearing that suspends both ends of a hanging mandrel that passes through the center hole of the electric wire drum, and the screw jack is in contact with the floor surface on which the base board is installed and the drive roller surface. A straight line averaged based on the locus of the center hole of various electric wire drums of different diameters is inclined at an angle with the floor surface, and the straight line is moved in parallel by a predetermined amount in a direction closer to the driving roller side. The bearing is installed at an angle with the starting point, and the bearing is opened to receive the shaft from the side opposite to the drive roller side, and the V-shaped lower piece is at an angle of 30 degrees with respect to the floor surface. It is characterized by being mounted at an angle of elevation.

In the figure, 1 is a base plate, 2 is a driving roller, 3 is a screw jack, 4 is a bearing with a V-shaped cross section, C is an electric wire drum, and 5 is a hanging shaft that passes through the center hole of the electric wire drum.

The device of the present invention basically includes a U-shaped base plate 1 in plan view, a driving roller 2 fixedly installed on the base plate 1, and a driving roller 2 on both sides of the base plate 1 in front of the driving roller 2. It is composed of a pair of left and right screw jacks 3 installed in an inclined state in a direction opposite to the roller side, and a V-shaped cross-sectional bearing 4 mounted inside each of the jacks 3 so as to move up and down by the jacking action. be done.

As shown in FIGS. 1 and 2, the drive roller 2 is used to control the rotation of the drum C by coming into contact with the outer peripheral portion of the wire drum C during use. 1st~

As shown in FIG. 5, the screw jack 3 draws the center hole locus A of various electric wire drums C with different diameters that are in contact with the floor surface 12 on which the base plate 1 is installed and the drive roller 2 surface, and uses this as a reference. The averaged straight line B is inclined at an angle with the floor surface 12. In other words, the angle that the straight line B makes with respect to the floor surface 12 is the inclination angle of the screw jack 3. Further, the screw jack 3 moves the straight line B by a predetermined amount in parallel in a direction toward the driving roller 2 side as shown in FIG. It is installed at the above-mentioned inclination angle, starting from the starting point.

As shown in FIG. 1, the bearing 4 has an opening so as to receive the hanging shaft 4 from the side opposite to the drive roller 2 side, and the V-shaped lower piece 4a thereof is connected to the floor surface 12. It is mounted at an angle of 30° with respect to the

The screw jack 3 includes a jack hosing 13 having a prismatic hollow structure, and a jack screw shaft 1.

8. Consists of a jack lifting motor 19 fixed to the lid 18, a coupling 20, and a strut 21. Also, the bearing 4 is a jack hose 13
It is attached to a bearing guide 22 incorporated within. The bearing 4 moves up and down by rotationally driving the lifting motor 19 of the jack 3, which rotates the jack screw shaft 14 and causes the bearing guide 22 to rise or fall within the jack hosing 13. Reference numeral 23 in FIG. 2 is an operation panel for operating the screw jack 3.

When using the apparatus of the present invention, the bearing 4 is first set lower than the height of the suspension shaft 5 of the wire drum by operating the screw jack 3, and then the wire drum C is lowered as shown in FIG. The core shaft 5 is scooped into the bearing 4 by rolling it on the floor surface 12 from the direction of the arrow E shown in FIG. The electric wire drum C is suspended in a raised manner and held in a state where it rides on the driving roller 2. At this time, the wire drum C is separated from the floor surface 12 and supported by the bearing 4 and the driving roller 2 (see FIG. 6). By rotating the driving roller 9, the rotation of the electric wire drum can be controlled. Note that bearing 4
If the wire drum C is further raised, the wire drum C can be released from contact with the driving roller. 24 in FIG. 6 indicates an electric wire.

〔Effect of the invention〕

Since the present invention has the configuration described in detail above, the following effects can be obtained.

There is no need to move the drive unit (roller) for various wire drums with different diameters, and it can be used as it is fixed.

Various wire drums with different diameters can be easily held by simply lifting and lowering the bearing with a screw jack, and at the same time, rotation can be easily controlled by pressing the outer periphery of the drum against the drive unit (roller). Can be done.

The entire device has a simple structure that is assembled on a base plate, and the device is not large-scale since the screw jack is only about the same size as the radius of the wire drum. Therefore, it is easy to install the device (it can be installed using only anchor bolts) and move it, and it is also economically advantageous.

Since the movable part consists only of a rotating mechanism, there are fewer failures, and if a motor is used as the driving force for the rotating mechanism, the device can be controlled entirely electrically.

Therefore, the device of the present invention can be used in electric wire winding lines, etc., and the effects produced thereby are extremely significant industrially.
