2 is a perspective view illustrating a state in which a bogie is separated in an embodiment of the present invention, and Fig. 3 is a perspective view showing a main part of the embodiment of the present invention Fig.

Referring to this figure, a flexible member winding apparatus according to an embodiment of the present invention includes a base frame 10, a winding member 20, a bundle width limiting member 30, a moving means 40, a rotating means 50 And a guiding means 60. The guiding means 60 includes a guiding means (not shown)

The base frame 10 has a winding member 20, a bundle width restricting member 30, a moving means 40 and a rotating means 50 at an upper portion and a guide means 60 at a lower portion thereof.

These base frames 10 are arranged on both sides at regular intervals, and a bogie 80 is provided in a space having a constant spacing.

A winding member 20, a bundle width restricting member 30, a moving means 40, and a rotating means 50 are formed symmetrically on the base frame 10 disposed on both members.

The winding member 20 is tapered so as to be gradually widened from one end closer to one end to the other end, and is fixed to a rotating shaft 21 disposed horizontally on the base frame 10, 50 so as to be capable of winding the flexible member R1 and to be movable in the horizontal direction for winding up and discharging the wound flexible member bundle R2.

The bundle width limiting member 30 has a through hole 300 formed at its center so that the winding member 20 can move through the through hole 300 and face the base frame 10 with a certain distance So that the flexible member bundle R2 wound on the winding member 20 has a certain width and the flexible member bundle R2 wound on the winding member 20 when the winding member 20 is spaced apart, To be separated from the winding member (20).

The bundle width limiting member 30 is rotated together with the rotation shaft 21 so as not to cause friction with the flexible member Rl wound when the flexible member R1 is wound around the winding member 20. [

The bundle width limiting member 30 which rotates together with the rotary shaft 21 is integrally fixed to the rotary shaft 21 and can be rotated together with the rotary shaft 21. The first bearing 71 fixed to the base frame 10, And can be rotated by the clutching means 70 that transmits the rotational force of the rotary shaft 21 while being rotatably supported by the rotary shaft 21.

The outer race 720 surrounding the bearing member 710 is fixed to the base frame 10 and one side of the inner race 730 located on the inner side of the bearing member 710 has a width And is fixed to one side of the restricting member so that the bundle width restricting member 30 can be rotated.

The clutching means 70 includes a rotating disk 750 having a plurality of magnets 760 pressed in the circumferential direction of the rotating disk 750 and fixed to the rotating shaft 21 and a retainer 740 are formed of a metal that is a magnetic body.

The magnet 760 has a magnetic force capable of moving the retainer 740 by magnetizing the retainer 740.

The retainer 740 is fixed to the inner race 730 and a gap of about 0.3-0.6 mm is formed between the retainer 740 and the magnet 760 of the rotary disk 750 so that the magnetic force of the magnet 760 acts on the retainer 740 . Therefore, the rotational force of the rotating shaft 21 is transmitted by the magnetic force, so that the bundle width limiting member 30 can rotate.

The clutching means 70 moves in the horizontal direction by a moving means 40 to be described later and when the rotary shaft 21 rotates the winding member 20 to wind the flexible member R1, The bundle width limiting member 30 is rotated in the state of being close to the bearing 71. [

On the other hand, a first sensing sensor 770 is installed on one side of the outrace 720 to detect when the rotating disc 750 is close to the magnet 760 by driving the moving unit 40 The driving of the moving means 40 can be stopped at the time when the magnet 760 reaches the closest position of the retainer 740. [

The moving means 40 includes guide rails 400 and 401, a moving base 410 and an actuator 430.

The guide rails 400 and 401 are fixed to the base frame 10 in the same direction as the axial direction of the rotary shaft 21.

The rotating shaft 21 is rotatably fixed to the second bearings 420 and 421 which are opposed and fixed to each other and are guided by the actuators 430 to the guide rails 400 and 401 Move.

The actuator 430 may be a reciprocating mechanism including a pneumatic cylinder and is preferably formed of a rodless cylinder to move the movable table 410 on the guide rails 400 and 401 .

As is well known, the rodless cylinder is made so that the magnet placed inside and the magnet outside are magnetically attached to each other with the cylinder barrel interposed therebetween. When the magnet inside is pushed by the force of compressed air, This makes it possible to reduce the size of the installation space compared with a normal double-acting cylinder.

The moving means 40 moves the pair of winding members 20 together with the rotating shaft 21 to bring the flexible member R1 into close contact with the winding member 20 And the wound member 20 is moved so as to be spaced apart from each other in order to discharge the wound flexible member bundle R2.

The rotating means 50 includes a first motor 500 and a power transmitting means 510.

The first motor 500 is fixed to the moving table 410 and moves together with the rotating shaft 21.

The power transmission means 510 includes a first timing pulley 511 fixed to a drive shaft of the first motor 500, a second timing pulley 512 fixed to one end of the rotation shaft 21, And a timing belt 513 connecting the first timing pulley 511 and the second timing pulley 512.

The guide means 60 is reciprocated by a distance between the reciprocating means 600 moving in the axial direction of the rotary shaft 21 and the bundle width restricting member 30 located at the right and left sides by the reciprocating means 600, And a guide 610 for guiding the flexible member R 1 to be wound and wound around the winding member 20.

The guide 610 is formed of two vertical rods through which the flexible member R 1 passes, and the flexible member R 1 is guided through the space formed by the two vertical rods.

Therefore, when the guide 610 is moved, the position where the flexible member R1 is wound at the winding member 20 is changed, so that the guide 610 reciprocates right and left, and the flexible member R1 ) Can be wound evenly.

The reciprocating means 600 includes a second motor 601 capable of normal and reverse rotations and a second motor 601 having one end fixed to the second motor 601 and rotating in a horizontal axis parallel to the rotation axis 21, A second sensor (604, 605) for limiting the range of movement of the slider (603), a second sensor (604, 605) mounted on the guide shaft (602) And a controller (not shown) for receiving the signals from the sensors 604 and 605 and controlling the operation of the second motor 601.

The guiding means 60 includes a flexible member Rl so that the flexible member R1 wound on the winding member 20 by the rotating means 50 can be alternately wound on the winding member 20 in the left- .

In addition, the reciprocating means 600 is fixed to the second bearings 420 and 421 so as to be rotated in accordance with an output signal proportional to the rotational speed sensed by the third sensing sensor 620 sensing the rotational speed of the rotational shaft 21 The reciprocating speed is adjusted.

That is, when the rotational speed of the rotary shaft 21 sensed by the third sensing sensor 620 is inputted to the controller, a pulse signal for driving the second motor 601 is outputted in proportion to the rotational speed of the rotary shaft 21, The speed at which the guide 610 is moved can be adjusted.

Accordingly, the lower the rotational speed of the rotary shaft 21, the slower the driving speed of the second motor 601 that feeds the guide 610 in proportion thereto. As the rotational speed of the rotary shaft 21 increases, The driving speed of the second motor 601 for conveying the guide 610 is increased, so that the flexible member R1 can be easily wound.

The carriage 80 is formed with a caster 800 so that the caster 800 can move and is separated from the winding member 20 and is opened upward to accommodate the rolled flexible member bundle R2 to be dropped thereon, A carrying handle 810 is formed.

The process of winding the flexible member R1 according to the present invention will be described.

FIG. 5 is a sectional view of the operation state of the embodiment of the present invention, and FIG. 6 is a side view showing a state in which the flexible member R 1 is wound according to the present invention.

5A, the actuator 430 and the movable table 410, which are opposed to and installed on the guide rails 400 and 401 on both the base frames 10, Is moved to the outside of the guide rails (400, 401) so as to maintain the spaced distance.

In this state, both the winding members 20 are located outside the through hole 300 of the bundle width restricting member 30. [

When the actuator 430 is driven in this state, the movable table 410 moves.

The reel 1 driving motor, the power transmitting means 510 and the rotating shaft 21 are fixed to the moving table 410. As the moving table 410 is moved by fixing the winding member 20 to the rotating shaft 21 The winding members 20 are brought close to each other.

The rotating disk 750 moving horizontally together with the rotating shaft 21 is rotated by the first detecting sensor 770 when the winding member 20 moves closer to the rotating shaft 21 when the winding member 20 is brought into contact with each other as shown in FIG. The driving of the actuator 430 is stopped by the signal output from the first sensing sensor 770.

At this time, the magnetic force of the magnet 760, which is fixed to the rotating disk 750, comes close to the retainer 740 and acts on the retainer 740.

The flexible member R1 is pulled out through the space between the two vertical rods constituting the guide 610 and pressed and fixed between the contact surfaces of the winding member 20, So that the surface is detachable.

When the flexible member R1 is attached to the winding member 20 as described above, the first motor 500 is driven.

The power of the first motor 500 is transmitted to the first motor 500 via the first timing pulley 511 installed on the drive shaft of the first motor 500 and the second timing pulley 512 fixed to the rotation shaft 21 through the timing belt 513 So that the rotating shaft 21 is rotated.

The rotating shaft 21 rotates and the winding member 20 fixed to the tip end of the rotating shaft 21 rotates simultaneously to wind the flexible member R1.

The rotating disk 750 fixed to the rotating shaft 21 rotates at the same time because the retractor is rotated by the magnetic force of the magnet 760 fixed to the rotating disk 750 so that the retainer 740, The friction between the flexible member R1 and the bundle width restricting member 30 that are wound around the winding member 20 can be minimized by rotating the bundle width limiting member 30 fixed to the bundle width limiting member 30 at the same time.

Here, the flexible member R1, which is wound around the winding member 20, is guided by the guide means 60 and wound.

That is, the guide 610 for guiding the flexible member R1 moves left and right together with the slider that moves as the second motor 601 rotates in the forward and reverse directions.

The control signal driven by the second motor 601 in the forward and reverse directions is generated whenever the slider moving left and right contacts the second sensors 604 and 605.

That is, when the slider moves to the left and reaches the second sensor 604 on the left side, the second motor 601 is driven in the reverse direction to move the slider to the right side, and the slider moving to the right side moves to the second When the sensor 605 is reached, a control signal for driving the second motor 601 backward is generated.

The guide 610 is moved and the position of the flexible member R1 wound around the winding member 20 is changed so that the guide 610 reciprocates right and left and the guide member is uniformly moved And the flexible member bundle R2 is formed.

When the size of the flexible member bundle exceeds a predetermined value, the driving of the first motor 500 is stopped and the rotation shaft 21, the winding member 20, and the bundle width limiting member 30 are stopped.

When the actuator 430 is driven in the reverse direction and the rotary shaft 21 of the first motor 500, the winding member 20, and the rotary disk 750 move together with the movable stage 410 as shown in FIG. 5A, The flexible member bundle falls from the virtual line A position to the virtual line B position as shown in FIG.

At this time, the outer circumferential surface of the winding member 20 becomes wider as it goes outward, and can be easily separated from the flexible member bundle, and the state of being wound by the bundle width limiting members 30 on both sides is placed on the bogie .

Thereafter, when the operator cuts the flexible member R1 at the winding-finishing position and transports the bogie, it is possible to easily and economically dispose a large amount of the flexible member R1.

The present invention has been described with reference to preferred embodiments.
