Abstract

PURPOSE:To obtain a high quality wire by putting the wire in a sigmoid-shape on a taking-off roller pair or a tension roller pair. CONSTITUTION:The wire W from a supplying part 1 provided with plural supplying reels 10 is welded in a welding stage 2. A pair of rolling rolls 15, 16 are provided and, after winding the wire around one roll 15 of them like turning- back, the wire is put into the S-shape by winding the wire around the other roll 16 like turning-back. A temp. control part 4 for heating or cooling is provided on the downstream side of this rolling stage 3. The wires are adhered with an adhesive applier 11 and a drying furnace 12 in an adhesion stage 5. In a taking-off part, a pair of taking-off rollers 22, 23 which are vertically parallel or a pair of tension rollers 20, 21 which are parallel back and front or vertically on the immediately upstream part of these taking-off rollers are provided. The wire W is wound in sigmoid-shape round the taking-off rollers 22, 23 or the tension rollers 20, 21. In this way, the generation of contact failure, dimensional error and scratching of the wire are prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for connecting a plurality of wires in a strip shape.

[0002]

2. Description of the Related Art Conventionally, as a method of manufacturing staples (staple staples), a plurality of wire rods are placed alongside each other to form a band, and an adhesive is applied to the wire rods and dried to integrate them.
Take up this band-shaped integrated wire connection band on a reel,
A method of sending to the next cutting and bending step has been developed (see, for example, JP-A-64-57935). In addition,
On the downstream side of the step of placing the wire rods along each other, there is provided a rolling step of passing the wire rod between a pair of upper and lower parallel rolling rolls to make the cross-sectional shape rectangular or the like. In addition, a pair of upper and lower parallel take-up rollers for feeding the wire are provided between the step of applying and drying the adhesive and the step of winding the reel thereafter.

[0003]

When the wire rods passed between the rolling rolls slip or the wire connecting strips passed between the take-up rollers slip, the rolling roll pair and the take-up roller pair are separated from each other. Since the tension of the wire rod stretched between them becomes excessive or insufficient, there is a problem that the wire rod may have defective adhesion, dimensional error, or scratches.

The present invention has been made in view of the above circumstances, and makes it possible to obtain a high-quality product by making the tension acting on the wire between the rolling roll pair and the take-up roller pair constant. It is an object of the present invention to provide a manufacturing apparatus for a wire rod connecting band.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention is a wire rod connecting belt manufacturing apparatus having a step of placing a plurality of wire rods along each other, a rolling step of each wire rod, and an adhering step of the wire rods to each other. Is provided, and the wire rod is wrapped around one of the rolling rolls in a folded shape, and then is rolled around the other rolling roll in an S-shaped manner. A pair of take-up rollers that are parallel to each other in the front-rear direction or the upper-lower direction or a pair of tension rollers that are parallel to each other in the front-rear direction or the up-down direction are provided immediately upstream of the take-off roller at the proper place on the side. It is also characterized in that the wire rod is hooked in an S shape.

[0006]

According to the present invention, the wire rod is adapted to be S-shaped on the rolling roll pair and the take-up roller pair or the tension roller pair. (Including) does not occur.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 schematically shows a manufacturing apparatus according to the present invention, in which 1 is a supply unit of a wire W provided with a plurality of supply reels 10 and 2 is a plurality of guide rollers (not shown) or the like. A juxtaposition process for laying the wire rods W on each other, 3 is a rolling process having a configuration to be described later, 4 is a temperature controller for heating (winter) or cooling (summer) the wire W at a predetermined temperature, and 5 is an adhesive. A bonding step in which a plurality of applicators 11 and drying ovens 12 are alternately provided, 6 is a take-up portion having a configuration described later, and 7 is a take-up step of taking up the manufactured wire rod connecting band on a take-up reel 30.

The rolling process 3 is provided with a pair of rolling rolls 15 and 16 which are vertically parallel to each other. Plural concavo-convex strips (not shown) for rolling the wire material W into a predetermined cross-sectional shape are provided on the outer peripheral surfaces of both rolling rolls 15 and 16 along the circumferential direction. These rolling rolls 15,
Of the sixteen, the wire W is first wound around the upper rolling roll 15 so as to be folded back in the backward direction from the top to the bottom, and after passing between the two rolling rolls 15 and 16, the wire W is wound on the lower rolling roll 16. It is wound so as to be folded back from the top to the bottom in the forward direction to draw an S-shape (inside out). The wire W fed from the lower rolling roll 16 is
It is guided upward by the guide roller 17 and sent to the next process (temperature control unit 4).

The take-up section 6 is a pair of take-up rollers 22 and 23 which are parallel to each other in the vertical direction, and a pair of tension rollers 20 and 21 which are installed in parallel with each other at a predetermined interval in the front and rear immediately upstream of the take-off rollers 22 and 23. And have. The tension roller 20 arranged on the upstream side is held at a position slightly higher than the tension roller 21 arranged on the downstream side.
Of these tension rollers 20 and 21, the wire rod connecting band is first wound around the tension roller 21 arranged on the downstream side so as to be folded back in the backward direction from the bottom, and then the tension roller 20 arranged on the upstream side. It is wound so as to be folded back in the forward direction from bottom to top so that it draws an S-shape (which is incomplete). The wire connecting strips for the take-up rollers 22 and 23 are sent out to the next step (the take-up reel 30) while the upper and lower surfaces thereof are sandwiched between their opposing faces.

In this way, the rolling rolls 15 and 16
On the other hand, the wire W is prevented from slipping, and the tension roller 20, 21 is prevented from slipping on the wire connecting strip. Therefore, the wire W that is stretched between these
The tension of the wire rod (including the state of the wire connection band) is maintained constant. The take-off rollers 22 and 23 are positioned so as to be displaced forward and backward like the tension rollers 20 and 21, and either one of the tension rollers 20 and 21 is removed to remove the wire rod from the take-up roller 2.
You may make it S-shaped on 2,23.

[0011]

According to the present invention, which has the above-described structure, the wire rod is hooked in the S shape in both the rolling process and the take-up portion. Therefore, at least the rolling roll pair and the take-up roller pair are provided. The tension of the wire rod stretched between them is kept constant. Therefore, the wire material is free from adhesion failure, dimensional error, and scratches, and a high quality product can be obtained.
