Description

[Detailed description of the invention] <Technical field> The present invention switches the feeding direction of the wire by distributing the wire to the left and right when winding wire rods such as steel wires and small diameter pipes on left and right winding drums in sequence. Regarding equipment.

<Prior art> As shown in FIG. 4, in the conventional wire rod feeding direction switching device, the wire 1 is transferred to the guide body by a wire rod feeding device (not shown) via a roller 5 disposed outside the guide body 1. 1 and the position detection device 7 of the wire 6
The roller moving cylinder 3 is driven by a signal from the guide member 1, and the roller 2 on the guide body 1 is brought closer to sandwich the wire. Thereafter, the guide body 1 was moved in the left-right direction by the cylinder 4 and guided to the left or right winding drums 8, 9.

However, the timing for pinching the wire rod and the timing for driving the cylinder 4 are very difficult, and therefore, high precision is also required in controlling the cylinder 4 for moving the guide body.

Further, the wire rod 6 sent out from the guide body 1 is configured to enter a right or left sorting body (not shown) having rollers 8A, 9A.
At this time, the wire rods 6 are distributed to the left and right by the movement of the guide body 1, but there is also a difficulty in determining the timing for sending the wire rods 6 to the distribution body during this distribution.

Furthermore, in the above structure, the air cylinder 3 for moving the roller and the cylinder 4 for moving the guide body are structurally required, which has the disadvantage of increasing cost.

<Purpose> Therefore, an object of the present invention is to provide a wire rod feeding direction switching device that can simplify the structure, reduce costs, and facilitate the distribution of wire rods.

<Embodiment> Hereinafter, an embodiment of the wire rod feeding direction switching device of the present invention will be described based on FIGS. A straight guide path 13 for introducing the wire rod 11 into the guide body 12, and a curved guide path 14 for feeding and guiding the wire rod 11 in the rightward or leftward direction continuously from the straight guide path 13 are formed, and the guide body 1
2, the wire rod rightward feeding posture A and the wire rod leftward feeding posture B of the curved guide path 14 are attached to the base 10.
The guide member 12 is rotatably supported by the guide member 12, and is provided with a rotating means 15 for rotating the guide member 12.

The guide body 12 includes a rear guide tube 16 in which the linear guide path 13 is formed, a front guide tube 17 arranged in the same linear direction as drum-side guide tubes 29 and 30, which will be described later, and the front guide tube. 17 and a connecting body 19 that connects the rear guide tube 16.

The connecting body 19 has three pairs of guide rollers 20A, 20B, and 20C arranged in parallel in the wire feeding direction on both left and right sides, and each guide roller 20A, 20
B, 20C are the rotating shafts 20a, 20b, 20
c is movable and fixed by screws 20d in long holes 19a, 19b, and 19c bored in a direction perpendicular to the wire feeding direction, so that the width of separation between the opposing rollers can be adjusted according to the diameter of the wire 11. It is composed of The guide rollers 20A, 20
Of B and 20C, the rear guide roller 20A is formed with a long hole 19a so as to be movable in a direction perpendicular to the guide direction C of the linear guide path 13, and the intermediate guide roller 20B is perpendicular to the guide direction C. An elongated hole 19b is formed so that the guide roller 20C can move in a direction slightly inclined from the direction in which the guide roller 20C moves, and an elongated hole 19c is formed so that the guide roller 20C can move in a direction further inclined from a direction perpendicular to the guiding direction C. . Furthermore, the intermediate position of each pair of guide rollers, the guide roller 20C and the intermediate guide roller 20B, is set at a position slightly eccentric to the right or left from the guide direction C.

The rear end of the rear guide tube 16 is rotatably supported by the support base 10A of the base 10 via a rear guide tube bearing 21, and the front guide tube 17 is rotated from the center of rotation of the rotary plate 22. The rotary disk 22 is eccentrically fitted and fixed, and is rotatably supported by the support base 10B of the base 10 via a front guide tube bearing 23.

An auxiliary guide tube 24 is provided on the rear end surface of the rear guide tube 16.
The rear part of the auxiliary guide tube 24 is formed in a trumpet shape, and the auxiliary guide tube 24 is also rotatably supported by the base 10 via an auxiliary guide tube bearing 25.

A pair of pinch rollers 26 for feeding the wire rod 11 into the guide body 12 are disposed on the rear side of the auxiliary guide tube 24, and the pinch rollers 26 are rotationally driven by a roller drive motor 27. There is. Furthermore, a tip position detection device 28 for detecting the tip position of the wire rod 11 is provided on the rear side of the pinch roller 26.
is installed.

The wire rod 11 is placed on the front side of the curved guide tube 17.
A right direction guide tube 29 and a left direction guide tube 30 for sending out in two directions are arranged at a constant angle θ in the left and right direction with respect to the linear guide path 13. It is externally fitted and fixed to the support body 31 of the stand 10. Furthermore, both the guide tubes 29, 3
0 and the left and right winding drums 8 and 9, the wire rod 1
A terminal position detection device 32 for detecting the terminal position of one terminal is provided.

As shown in FIG. 3, the rotation means 15 includes a pinion gear 33 externally fitted and fixed to the linear guide tube 16.
, a rack 34 that meshes with the pinion gear 33 to rotate the gear 33, and an air cylinder 36 that moves the rack 34 in the left-right direction along a rack guide shaft 35.

Next, to explain the operation, in the rightward feeding position A shown by the solid line in FIG.
It is guided while curving to the right through the curved guide path 14 formed by C, passes through the guide tube 17, exits the right guide tube 29, and is sequentially wound around the drum 8.

Then, the wire 1 is detected by the terminal position detection device 32.
1 is detected, the air cylinder 36 is driven by the signal to move the rack 34 to the right (or left), and the pinion gear 33 is moved counterclockwise.
Rotate 180°. Then, the guide body 12 rotates in the same direction, and the guide tube 17 takes the position shown by the imaginary line in the figure, that is, the leftward delivery position B together with the rotating disc 22. When wire rod 11 is sent in this state, wire rod 11
are the guide rollers 20A, 20 of the curved guide path 14.
It is sent to the left by B and 20C, and the left drum 9
It is wound up.

Next, when the following wire rod 11 exits the left direction guide tube 30 and its terminal end is detected by the terminal position detection device 32, the air cylinder 36 is driven and the pinion gear 3
3 rotates 180° clockwise. As a result, the rightward delivery posture A is assumed again.

Therefore, the guide body 1 with the curved guide path 14
2 is rotated by 180 degrees, and the guide tube 17 faces the right guide tube 31 and the left guide tube 30 on the drum side, so the wire rod 11 can be easily distributed to the left and right. . Furthermore, since the only cylinder is the cylinder 36 for rotating the guide body, it is possible to reduce costs.

<Effects> As is clear from the above description, the present invention includes a guide body that guides the wire on the base, a linear guide path for introducing the wire into the guide, and a linear guide path that is continuous with the linear guide path. A curved guide path for feeding and guiding the wire rod to the right or left is formed, and the guide body is
Wire rod feeding, characterized in that the base is rotatably supported to switch between a rightward wire rod feeding position and a leftward wire rod feeding posture of the curved guide path, and is provided with a rotating means for rotating the guide body. This invention relates to a direction switching device.

Therefore, according to the present invention, the wire can be distributed to the left and right by rotating the guide body.
This has excellent effects such as simplifying the structure of the entire device, reducing costs, and facilitating the distribution of wire rods.
