Description

[Detailed description of the invention] This invention relates to a falling guide device for a loop-shaped wire, and in particular, a falling guide that guides a loop-shaped wire that is falling is controlled by a rotating body that rolls into contact with the wire on both sides of the wire. By holding down the falling wire from both sides and letting it fall, it is possible to prevent the wire from swinging, thereby making the loop of the wire falling and being supplied onto the conveyor regular, and forming the wire into a loop shape. Enables high-speed operation of equipment.

2. Description of the Related Art Conventional examples of drop guide devices for loop-shaped wire rods include those shown in FIGS. 1 and 3.
That is, in FIG. 1, 1 is a block for forming a loop, and this block 1 has an upper stage 1a and a lower stage 1b.
The outer periphery has a circular cross section, and the wire 2 is wound around the outer periphery as described later to form the wire 2 into a loop shape. A rotary table 3 that rotates horizontally concentrically with the block 1 is arranged below the block 1, and the rotary table 3 includes pulleys 4, 5, 6, a tension adjuster 7,
A deflector 8, a straightener 9, a presser roll 10, and a falling guide 11 are installed. Below the turntable 3,
A conveyor 12 is arranged to convey the wire rod 2 to the next process. The block 1, the rotary table 3, the rotary table 3
pulleys 4, 5, 6, tension adjuster 7,
By the deflector 8, straightener 9, and presser roll 10,
A device 13 for forming the wire 2 into a loop shape is constructed.

The wire 2 is guided from above, passes downward through the center of the block 1, passes through the pulleys 4, 5, 6, and the adjuster 7, and is wound several times from the back side of the block 1 to the upper stage 1a, and is then wound from the back side of the upper stage 1a. correction device 8, correction device 9,
After passing through the presser roll 10 and being wound around the lower stage 1b of the block 1 from the back side ten times, it passes through the drop guide 11 and reaches the conveyor 12. By the rotation of the rotary table 3, the pulleys 4, 5, 6, tension adjuster 7,
The deflector 8, the straightener 9, the presser roll 10, and the drop guide 11 horizontally rotate together to form the wire 2 fed from above into a loop shape in the block 1, and drop it onto the upper surface of the conveyor 12. do.
At this time, the falling guide 11 guides the wire 2 that is dropped and supplied from the device 13 to the conveyor 12.

However, in such conventional examples,
Since the drop guide 11 was composed of only a simple frame with a large internal space, when the rotary table 3 was rotated to form the wire rod 2 into a loop shape, the wire rod 2 would become loose due to the influence of centrifugal force, as shown in FIG. comes into contact with the falling guide 11, causing the wire 2 to shake, and as a result, the falling position of the wire 2 below the falling guide 11 often becomes unstable. Then, as shown in FIG. 2, the loop-shaped wire rods 2 supplied onto the conveyor 12 are arranged in a disordered manner and are no longer regular, resulting in a problem that the post-processing of the wire rods 2 is hindered. . In particular, when the rotational speed of the rotary table 3 increases, the disturbance of the wire rod 2 increases, making it difficult to operate at high speed.

This invention was made by focusing on such conventional problems, and its purpose is to make the loop of the wire rod falling onto the conveyor regular by preventing the wire rod from swinging out.
Another purpose is to enable high-speed operation of an apparatus for forming a wire into a loop shape.

Therefore, the feature of this invention is that a block with a circular periphery is fixed with the center line facing up and down,
A rotating table is installed below the block to rotate the wire around the center line in a plane orthogonal to the center line to wind the wire around the block, thereby configuring an apparatus for forming the wire into a loop shape. Between this device and a conveyor that is located below this device and conveys the loop-shaped wire rod that has fallen from the block to the next process, it is attached to the rotary table and faces the falling path of the wire rod, and is connected to a conveyor that carries the falling wire rod. A falling guide is arranged to guide the wire, and the falling guide is composed of a rotating body that rolls into contact with the wire on both sides of the wire, and a member that supports the rotating body.

Next, this invention will be explained based on the embodiments shown in FIG. 4 and below.

Since the device 13 for forming the wire into a loop shape is the same as that of the conventional example, in this embodiment, the lower stage 1b of the block 1 forming a part of the device and the rotary table 3 that rotates horizontally below it are used. are shown, and the others are omitted. Further, the conveyor 12 disposed below the rotary table 3 is also the same as in the conventional example, and furthermore, the wire rod 2 is formed into a loop shape by the device 13, and this is dropped and supplied onto the conveyor 12, which is the same as in the conventional example. are the same.

A falling guide 11 is installed below the rotary table 3 to face the falling path of the wire 2 and guide the wire 2. This drop guide 11 consists of two rotating bodies 15 attached to a frame 14. The frame 14 is fixed to the rotating table 3, and the rotating body 15 is composed of vertically and mutually parallel rotatable rollers, and the gap between both rotating bodies 15 is set to the same size as the diameter of the wire 2. has been done.

FIG. 6 shows details of the drop guide 11. That is, elongated holes 14a are formed on the upper and lower sides of the frame 14.
are opened, the ends of which are inserted, and the stepped bolts 16 are fixed to the frame 14. Stepped bolt 1
6, the center part is thicker than the threaded parts at both ends, and the stepped part 16a between the two hits the inside of the frame 14, so that even if the nut 17 of the threaded part is tightened, the frame 14
The upper side and the lower side are prevented from deforming in the direction of approaching each other. A rotating body 15 is rotatably fitted around the outer periphery of the central portion of the stepped bolt 16 .
The gap between the rotating bodies 15 can be made by loosening the nut 17.
Adjustment is made by moving the stepped bolt 16 along the elongated hole 14a. Thereby, this drop guide 11 can accommodate wire rods 2 of various thicknesses.

In this embodiment, the fall guide 11 is configured as described above, but in this invention, it is sufficient to configure the two rotating bodies 15 so that they roll into contact with both sides of the wire rod 2, so the frame 14, the rotating bodies 15,
The shape and structure of the stepped bolt 16 are not limited to those of the embodiment described above.

By operating the device 13 for forming the wire rod into a loop shape, the wire rod 2 is formed into a loop shape and is fed down from the lower stage 1b of the block 1 toward the conveyor 12. A falling guide 11 moves in a circular orbit to guide the falling wire 2. At this time, the rotating body 15 is in rolling contact with the wire 2 from both sides in the horizontal direction, and since the rotating body 15 does not move in the centripetal and centrifugal directions of the circular orbit, the position where the rotating body 15 guides the wire 2 is always kept in a circular orbit. Therefore, the position of the falling wire rod 2 is on the conveyor 12 corresponding to the circular orbit, and since the conveyors 12 are operated at the same speed, the loop-shaped wire rod fed onto the conveyor 12 2 is a conveyor 12 as shown in FIG.
always at the same position in the width direction of the conveyor 12
They are always arranged at the same pitch in the direction of movement and are conveyed to the next process in a regularly arranged state.

At this time, since the rotating body 15 forming the drop guide 11 is rotatably fitted onto the stepped bolt 16, the frictional resistance between the two due to the rotating body 15 being in contact with both sides of the wire 2 is Be as small as possible.

As explained above, according to this invention, the device is provided at the bottom of the device for forming the wire into a loop shape.
A falling guide for guiding a falling loop-shaped wire rod is configured with a rotating body that rolls into contact with the wire rod on both sides of the wire rod, so that the falling wire rod is held down from both sides and allowed to fall. For this reason,
Since the wire rod is prevented from swinging while falling, the loops of the wire rod fed falling onto the conveyor are regularly formed at the same position in the width direction of the conveyor and at the same pitch in the direction of movement of the conveyor. Therefore, there is an effect that processing of the loop-shaped wire rod in the next step can be facilitated. In addition, according to this invention, both sides of the falling wire are held down by rotating bodies, so even if the device that forms the wire into a loop shape is operated at high speed, the wire does not shake. It also has the effect of improving processing efficiency during operation.
