Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire / cable supply device for stably supplying electric wires or cables for continuous processing in a production line while applying a constant tension.

[0002]

2. Description of the Related Art Various accumulators have been employed for supplying electric wires and the like continuously and stably while applying a constant tension. It has long been known that moving sheaves such as moving sheaves are arranged between a plurality of fixed sheaves, and the pulling action is always applied to these moving sheaves to change the distance between the fixed sheaves and the moving sheaves, and thus electric wires, etc. Is constantly supplied, and the supply is performed while the storage line action is being performed. For example, as shown in FIG. 2, in a conventional electric wire supply device, a storage line portion 1 and a moving sheave 1 of the storage line portion 1.
The storage sheave 1 has a fixed sheave 1b as a guide on the supply side of the electric wire. When the electric wire is conveyed and supplied, the wire is input from the fixed sheave 1b side, wound around the moving sheave 1a, and output from the fixed sheave 1b. When this electric wire is supplied, the moving sheave 1a is always provided with a pulling action to maintain the electric wire tension. When the supply (input line) is stopped or the output line is stopped, the moving sheave 1a is the fixed sheave 1
It is arranged so as not to interfere with the continuous supply of electric wires by being close to the side b or separated from the fixed sheave 1b.

[0003]

However, it is useless to keep the traction force applied to the moving sheave such as a moving sheave at all times, and a considerable amount of energy is wasted during 24-hour work. An object of the present invention is to provide an electric wire / cable supply device provided with an energy saving type accumulator device in which the moving sheave is towed only when necessary without constantly applying the towing action to the moving sheave. Another object of the present invention is to provide an electric wire / cable supply device provided with an accumulator device that operates reliably with a simple mechanism.

[0004]

The present invention has the following constitution in order to achieve the above object. It consists of a fixed sheave and a moving sheave, and has an electric wire supplied from the fixed sheave side to have a storage line function and a tension applying function.
That for 牽 Hikitsukuri is disposed an accumulation device which is offered to the mobile sheaves, the wire and cable feeding device for performing a winding or processing while continuously feeding wire or cable, the fixed sheave and the outgoing line side Convertible guide roller
Disposed tensioning unit comprising a buffer unit and a dancer member between, the mobile sheaves of said accumulating device, wire or
Or cable supply start, supply stop, winding stop
In addition , the electric wire / cable supply device is characterized in that a traction action by a power source is applied to actuate the storage line function only at the start of winding and winding .

The above object can be achieved by a structure in which the buffer section is a buffer cylinder or a structure in which the dancer member is pushed or pulled by the buffer cylinder and can reciprocate with a constant tension. The electric wire and cable supply device of the present invention continuously supplies electric wires and the like, and when processing or winding, the tension of the electric wires or the like is kept constant by the tension applying section with the moving sheave in the accumulator fixed. Is held.

In the electric wire and cable supply device of the present invention configured as described above, the tension applying device is arranged at the outgoing line position in the storage line portion, so that the electric wire or the like is continuously supplied for processing the electric wire or the like. At the time of processing entry when transporting,
Since the tension is constantly applied, it is possible to stably convey and supply the electric wire and the cable.

Further, the electric wire and cable supply device of the present invention constantly applies tension to the conveyed electric wire or the like by the dancer member at the time of processing entry when continuously supplying the electric wire or the like for processing the electric wire or the like. It is possible to add and perform line-in work or line-out work. Therefore, without maintaining the pulling state of the moving sheave by the power of the pulling part, the moving sheave is fixed at a near point position close to the fixed sheave or a far point position separated by a maximum distance from the fixed sheave to continuously connect the electric wire. Since it can be transported, it is possible to save traction power for pulling the moving sheave.

In the configuration of the present invention, since the cushioning member is arranged, it is possible to sufficiently deal with the fluctuation of the tension of the electric wire or the like which is the material to be conveyed during the feeding and conveying of the electric cable and the excessive load. There is no. In particular, since the dancer is pushed out or pulled by the buffer cylinder, a constant tension is always applied by keeping the pressure of the cylinder constant. In addition, the structure is simple because it includes one buffer.

In the electric wire and cable supplying apparatus of the present invention thus constructed, the moving sheave is fixed at the initial position, and thereafter the electric wire and the like are continuously supplied (entry) without applying a traction force to the moving sheave or Since it is possible to work on the outgoing line, the energy for giving the traction force to the moving sheave is saved.

BEST MODE FOR CARRYING OUT THE INVENTION An electric wire / cable supply apparatus of the present invention will be described below with reference to an embodiment shown in the drawings. Figure 1
FIG. 1 is a schematic explanatory view showing an embodiment of an electric wire / cable supply device of the invention. FIG. 2 is a schematic explanatory view of a conventional electric wire supply device.

A storage line 1 is composed of a fixed sheave 2 fixed to the entrance side and a movable sheave 3 movably mounted on a track laid on the floor, and fixed to a fixed portion 3a of the movable sheave 3. It is connected to the power source of the tow unit 4 by a tow line 4a. The storage line portion 1 is set with a fixed sheave 2 at a near point position N of a moving sheave 3 in close proximity and a far point position T farthest from the fixed sheave 2, and the moving sheave 3 is set at a far point position T. At one point, I store electric wires, etc. Reference numeral 5 denotes a tension applying section, which is composed of a dancer 5a and a buffer cylinder 5b, and a rod supporting the dancer 5a is fitted in the buffer cylinder 5b. Reference numeral 6 denotes a conversion guide roller for discharging the wire L or the like that has exited from the tension applying section 5.

The operation of the electric wire / cable supply device of the present invention having the above-described structure will be described. From the original winding (not shown), an electric wire or the like L is inserted onto the fixed sheave 2 of the storage line portion 1, wound around the moving sheave 3, returned to the fixed sheave 2 side, and output. The wire L or the like is wound around the dancer 5a and goes out via the conversion guide roller 6.

[0013] During processing incoming line when you continuously fed wire or the like for the processing of wire or the like in the wire and cable feeding device of the present invention, the distance between the fixed sheave 2 and the mobile sheave 3 is maximum distance far The moving sheave 3 is stopped at the point position T to store the wire, and the wire L or the like that has entered is conveyed to the dancer 5a of the tension applying unit 5 via the fixed sheave 2 and the moving sheave 3, and the wire L is tensioned. In this state, the line goes out through the conversion guide roller 6. When such wire-entry work is stopped, for example, when connecting the electric wire L or the like of the next original winding roll, the power source of the towing unit 4 is operated to move the moving sheave 3 of the storage line unit 1 to the fixed sheave 2 side. Get closer. At this time, the moving sheave 3 is moved while checking the position of the dancer 5a. After the wire connection work is completed, the wire output work of the wire L or the like is started, and the moving sheave 3 is returned to the initial far point position T to continue the wire input work.

Further, at the time of exiting when the electric wire L is continuously wound after the processing is completed, the distance between the fixed sheave 2 and the movable sheave 3 is set to the shortest point N, which is the shortest distance. The power source of the towing unit 4 is activated to move and fix the moving sheave 3 to release the towing force. The electric wire L entered from the fixed sheave 2 passes through the moving sheave 3 and the dancer 5 of the tension applying unit 5.
It is wound via the conversion guide roller 6 in a state where a constant tension is applied by a. When the lead-out work by winding the electric wire or the like L continues and the lead-out is stopped to replace the take-up roll, the moving sheave 3 is separated from the fixed sheave 2 by the pulling operation of the pulling unit 4 and the far point. When the take-up roll is moved to the position T and the take-up roll can be taken up, the moving sheave 3 is moved by the operation of the towing unit 4 to the fixed sheave 2
It is returned to the near point position N close to the side and fixed, and the winding operation is performed.

In the electric wire / cable supply apparatus of the present invention, the buffer cylinder is used in the embodiment shown in the drawings, but it goes without saying that a general buffer spring may be used for this portion.

[0016]

The wire / cable feeder of the present invention is
Since the traction force is not constantly applied to the moving sheave in the storage section, this power can be suspended. Further, since the moving sheave is in a fixed state, noise can be prevented, and since tension is applied by the dancer, stable feeding and supply of electric wires and cables can be performed.
