Abstract

PURPOSE:To continuously supply a wire rod to a straight line machine, in a stable bent state and at a high speed, by once drawing out the wire rod from a wire rod coil placed vertically to its upper high place, and after that, putting back tension, and giving bending in a specified direction. CONSTITUTION:A wire rod 10a is drawn out from a coil to its upper part, its entanglement is loosened while it is made to ascend in a guide cylinder 6, and it is guided naturally by sieves 7, 8 and is entered into a descaler 2. After descaling in that place, tension is applied between the descaler 2 and a straight line machine 4, and bending in a specified direction is given by a winding drum 3. Accordingly, a state that the wire rod 10a enters into the straight line machine 4 is stablized, and linearity by linear working is stabilized. On the other hand, the coil which is being used does not rotate, the coil 10 which is used next can rotate, a jointing work between the coils is executed by a welding machine exactly and quickly, and also replacement of the coil is executed quickly by a quick rotation of a turning disk 13 of a driving device 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rounding method and apparatus for supplying vertical reinforcement bars to a straightening machine in, for example, a rebar cage automatic assembly twin for a bar 10F11.

Conventionally, Sagrai stands have been equipped with a support mechanism that allows the rewinding and rotation of the reinforcing bars while putting a compact tension on them when pulling from the straight machine side.
Wrinkle: It was not possible to weld the tip of another twill O rebar to the end of the twill O rebar, and the straight line machining had to be interrupted every time the O rebar was joined. Moreover, the reinforcing bars wound around the rails are often tangled, and when you apply a grasshopper tension cord and unwind and turn the round 0, the tangled 10- is fixed instead, so it will not become loose if you pull out the reinforcing bars during use. There was a risk.

Therefore, it has not been possible to supply reinforcing bars to the straightening machine continuously and at high speed using the conventional O-Sagrai stand.

In the past, it has been shown that the height at which the O reinforcing bars are paid out from the rail is kept at the same level as the reinforcing bar transfer height in a straight line machine.
According to Volume 11, the direction of the direction of the reinforcing bars is not fixed before entering the straightening machine, and the straightening of the reinforcing bars cannot be done accurately and uniformly. In order to prevent the adverse effects of heat from the No. 11 heat during the welding process, it was necessary to keep the rebars waiting for welding in a straight line and to make the welding strength largely uniform. ◎Therefore, it was necessary to keep the rebars in a constant O-bend state for a straight machine. It was necessary to supply.

This invention @Hiro This was invented to solve the above-mentioned conventional O problem, and the line #O for a straight line machine can supply *V continuously, at high speed, and stably in a #fist state to a straight line machine.
The main objective is to provide a supply method and 70 equipment.

-Features of the present invention: Once the wire is pulled out to the upper part of the round wire coil in the round wire coil, and the wire is given a predetermined direction with a pack tension applied to the armpit wire before entering the straightening machine. A nappy stand equipped with a wire rod guide mechanism and a wire device mechanism on the upper and lower sides of the present invention, and a wire rod with back tension so as to apply a brake to the feed of a straight line machine via the wire rod. An example of the present invention apparatus used in the present invention method, including a tensile force applying device for applying the voltage and a winding drum for winding the wire, will be explained below with reference to FIGS. 1 to 3.

Ad support stand in the figure! 1 Hiro day skates, S is the winding trunk, and these are arranged sequentially on the 40-person side of the straight machine.The naptsui stand is equipped with a wire guide mechanism at the top and an attack mechanism 1 at the bottom. There is.

On the wire guide mechanism, a 1-meter frame 60 supports a guide tube 6 made of nine reinforcing bars with a taper extending downward at the base of the column in a method (i) not shown, and the pedestal 60 is located directly above the armpit guide tube 60. A pair of left and right sheeps 1.8 are supported in the girder part so that the V-P OII material threading parts correspond to the upper and lower sides through the girder part so that they can be rotated horizontally around the armpit wire threading part. @ Tomiru alignment mechanism md Center upper part of the horizontal support base 9 Wc**t: Z 1 point of tapered chamfer n that can be molded at the intestine and base! In order to quickly change the coil used, the guide tube 6 of the wire guide mechanism, which is located directly below the wire guide mechanism, and the drive unit UK, which can be rotated horizontally, are used to quickly change the coil used. The above-mentioned stacking device mechanism 1 is supported so as to be rotatable and non-rotatable when in use. An external Kmm horizontal machine with a near-swivel plate is disposed in the pile device mechanism B, 1.

Disscaler 2 When pressure i material is used for the wire material, high frequency i! At the same time, a tensile force is applied to the wire #101 to apply a tensile strength mark to the straight line machine 40 through the wire rod 10a to apply tension to the linear machine 40. It fulfills its role as a device for 4 hours.

Winding drum: s#i drive device electric layer, can run vertically, wire rod l
OA is wrapped many times, 9, straight line 41! Make one turn at a speed that does not impair the function of the turn.

To explain the method of the present invention using the above-mentioned fine wire rod feeding device, first, the device is installed; From there, I encountered the die scaler, and before entering the straight line machine, I wrapped the material on the armpit winding drum 3, applied the compaction tension to the wrinkled skate Svc, and wrapped it in the axillary winding drum 3 in good condition. ) This is a method of applying bending in a certain direction.

In the above configuration, the wire W1 is pulled upward from the trout and is untangled by the lever that ascends inside the guide tube 6, and is pulled out in the direction of the coil axis to become IKh and become the 1111j1 scented metal. After being weakened, Schipf was guided by 8 without any difficulty and moved from a high place to Disscaler 8.
During this time, it smoothly enters the descaler 3 due to the bending effect due to its own weight. After being descaled by the disscaler, a tensile force is applied between the wrinkle scale and the straight liner 4, and the winding cylinder 3 bends it in a certain direction before entering the straight liner. Therefore, the situation in which the wire rod 10a enters the straightener 4 becomes stable, and the straightness obtained by straightening is stabilized. In addition, the wire can be drawn out from the coil reliably and smoothly without any entanglements 174. In this case, the oil 1 in use does not rotate and will be used from now on; the oil mackerel can be rotated, and the filling work can be done reliably and quickly (by welding machine U), and the oil O can be replaced. This can be done quickly by turning the turning machine XIO rapidly 180'm times by driving the electric layer, and from the turn, the wire drawer can be continuously expanded and turned.

In addition, the support twist stand lO wire guide mechanism Muhiro upper and lower O
However, as shown in Fig. 4, an O-shaped guide with bells attached to both ends of the cylinder is suspended from the surgical area of the pedestal 8, and a round or O guide may also be used. ” foreshadowing material supply direction (straight line machine 401i material feeding direction) and, for example, 4sO
It is preferable to adjust it so that tkjP and the axillary wire rod a are accurately guided without compromising the movement caused by the rigidity of the wire rod aO being pulled out. The guide tube 6 is made of reinforcing bars, but may be made of iron plates as shown in the diagram.

Furthermore, the supply stand 10:2 ile arrangement mechanism 110
It was made in 1120 years ago, but as shown in Figure 1, it is possible to see the twill theory.
An enlarged part with a guide @'11 that is continuous with the box and gradually expands its diameter is detachably attached to the part (not shown), which may be a spear. Because it was pushed out by the part M to the line #-unexpectedly, 1 mi # intestine &
The work M is very strong (na) preferable, and the worker O is safe! Since k is the thickness, it is preferable to provide a removable cheap fence for this.

The method of the present invention involves setting the coils at m intervals and pulling out the wire up to the upper part of the coil. Since it has a large structure that allows it to be twisted and closed together with the crumbs, it is possible to securely hold one piece of material into the scraps. Moreover, you don't have to make Coil Hiro 1iii@;
The work can be done reliably and quickly.

Then, when the wire enters the straight machine, a pack tension is applied to the wire and the wire is bent in one direction.
The supply situation for the straight line machine is stabilized, and the straightness of the straight line process is also stabilized accordingly, and the zero-order process does not require any ingenuity as in the past.

Therefore, according to the method of the present invention, it is possible to feed wire rods continuously and at high speed to a straightening machine.

The apparatus of the present invention has an effective and extremely simple configuration for use in the above-mentioned method of the present invention.
It is compact and inexpensive, reduces maintenance, and enables high-speed continuous straight line machining.
