Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for manufacturing two vertically symmetrical flat meshes in which horizontal lines protrude in vertically opposite directions with respect to vertical lines located on a plane called an upper tool. It is.

When manufacturing flat netting, it is common to arrange multiple vertical lines parallel to each other on the left and right, supply horizontal lines one after another perpendicular to these, and fix the intersections of the two by welding. . In order to manufacture this continuously, a method is adopted in which vertical lines are continuously fed out and horizontal lines are sequentially fed perpendicularly to the vertical lines.
The arrangement of the horizontal line (2) and the horizontal line (2) are exactly the same, for example, as shown in FIG. 6, they are all located on either the horizontal line (2) or the vertical line (1).

Therefore, if several sheets of the same flat mesh are stacked one after another, for example, with the horizontal line (2) on the top, the height H will be 7 times the thickness of one sheet of flat mesh. ,
The more the same items are stacked in the same direction, the higher they become by the thickness of one sheet of flat screen.If the R line (1) and horizontal line (2) are thin, the height is not a big problem. I wonder if the thickness of the vertical line (1) and horizontal line (2) is about 3 to 5 am, for example, and if you stack 1 f sheets, it will be quite tall, making it difficult to store and transport. This is difficult and may cause the load to collapse during transportation.

The present invention was devised with the aim of eliminating these drawbacks, and the vertical line is placed at the 1st position.
The upper vertical line has a horizontal line on its side, and the lower vertical line has a horizontal line below it, symmetrically vertically.
It is designed to form two flat nets.

Embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in Figure 1, a plurality of vertical lines (Ia) and (Ib) are drawn on the plane of the upper and lower upper tools. These can be mounted on the upper and lower sides of a table (4) that can be reciprocated, and the reciprocating movement of the table (4) creates vertical lines (4a) and (1b) on the plane of the upper tool, respectively. Let it roll out.

The feeding device (3) shown in Fig. 1 is a pole chunk, and as shown in Fig. 2, it has two upper and lower spheres (3a),
(3a) is installed in a room with inclined walls (3b). When the table (4) moves forward, two spheres (3a) as shown in FIG.

A part of the outer circumferential surface of (3a) comes into contact with the inclined wall (3b), as if pressing, and clamps the vertical line inserted between both spheres (3a) and (,3a). In addition, the table (4
), as shown in Fig. 2(b), 2
A part of the outer circumferential surface of the two spheres (3a) and (3a) does not come into contact with the inclined wall (3b), so that the force exerted by the vertical line at 4 o'clock in front of the table (4) is eliminated. ing. Therefore, the vertical line is drawn out only when the table (4) moves forward (forward), and the vertical line is drawn out when the table (4) moves backward (backward), and the vertical line is drawn out when the table (4) moves back and forth. It is possible to extend the line 111α times.

In addition, the pole chuck also performs the function of preventing the rolled-out vertical line from returning.

In front of this feeding device (3), one fixed electrode (6) is placed between the two vertical conveyance paths (upper and lower), and upper and lower electrodes (6) are placed above and below the fixed electrode (5) so as to be in contact with the fixed electrode (5). Insert the capacitive electrode (6) vertically symmetrically.

On the other hand, above and below the two vertical lines (Ia) and (ib), horizontal lines (2a) and (2b) perpendicular to the vertical lines (1a) and (1b) are connected to the identification electrodes (5). A horizontal wire supply device (7) is provided to supply the welding electrode (e+ +a).

As the horizontal line feeding device (7), a pair of left and right chain conveyors with locking pawls can be used, and the horizontal line (7) can be used to feed the horizontal line (t') from above to below or diagonally from below to above as shown by the chain line in Figure 1. The chain conveyor is arranged so as to be able to supply the horizontal lines (2a) and (2b), and the horizontal lines (2a) and (2b) are fed in a horizontal state by means of locking claws provided thereon.

Next, a working process for vertically symmetrically manufacturing two sheets of flat mesh based on the apparatus shown in this embodiment will be described.

Due to the reciprocating movement of the table (4), a plurality of vertical lines (Ia) and (Ib) are drawn out in parallel to the left and right on the plane of the upper tool, and are sent above and below the fixed electrode (6) and twisted. .

The plurality of vertical lines (1a) on the upper side are supplied with the upper horizontal line supply device (7), and the plurality of vertical lines (1b) on the lower side are supplied with the lower one
This is a horizontal line (2a) by the lower horizontal line supply device (7).

(2b) are respectively supplied.

At this moment, the upper welding electrode (6) moves downward, and the lower welding electrode (6) moves upward, forming one fixed electrode (6).
), and the plurality of vertical lines (1a) and horizontal lines (2a) are connected at each intersection point in the upper and lower two positions, and the plurality of vertical lines (1b) and horizontal lines (2b) are connected at each intersection point. be welded.

Next, when the table (4) performs a second reciprocating motion, each vertical line (Ia), (1b) is a constant path 1! III (1 pitch), and in the next position, the upper and lower horizontal wire supply devices (7), (,71 and welding electrode ffi+
, (6) perform the second operation, and the next horizontal lines (2a) and (2b) are welded to the vertical lines (1a) and (ib).

By repeating this operation, multiple vertical lines (1a)
The horizontal lines (2a) and (2b) can be welded at predetermined intervals while feeding out the welding wires (1b) one pitch at a time at different positions.

Of the two flat meshes manufactured on the plane of the upper tool, the upper one (3) is placed on the horizontal line (2a) or above the vertical line (1?) as shown in Figure 3. and the lower one FB+ is the vertical line (1b) as shown in Figure 4.
The horizontal line (2b) is located on the lower side. That is, upper and lower 2
FB+ is a vertical line (Ia).

When carved into (1b), the horizontal 1it (2a) and (2b) are vertically symmetrical and protrude vertically and oppositely.

Therefore, when this long product is cut into predetermined dimensions and stacked, the lower flat screen (vertical line (1b) of B+) is cut as shown in FIG.

(1b) Since the vertical line (1a) of the upper flat mesh (3) is completely folded between them, the two vertically symmetrical flat meshes (5) and (B)
The height h when stacked is smaller than the height H when two stacked in the same direction (11(H),
The height when stacked can be made as small as possible. In other words, no matter how many sheets of flat mesh are piled up, the height is at least lower than before, which is extremely convenient in terms of storage and transportation.

In addition, vertical lines (1a), (1b), horizontal lines (2a),
(2b) is shown in Figure 1 (1a'), (1g), (2a
f) l (If the wire is wound around the Nicoil stand (8) so as to point in two directions f, and then pulled out one after another, two sheets of flat mesh can be manufactured continuously and efficiently.

In the figure, (9) is a device that removes the curl of the vertical wire wound on the coil stand (8) and straightens it into a straight line. In the example, the horizontal wire wound on the coil stand (8) is straightened by removing the curl at the part indicated by (10) and then cut to a predetermined length to form a vertical wire ( Ia).

(1b).

According to the present invention, it is possible to form two flat nets vertically symmetrically, so when stacking them, the vertical line (1a) to the upper flat screen (Bl vertical line (1b
),, (ib) It can be placed completely between the stacks, prevents the cargo from collapsing, and even when stacked, the height can be lower than in conventional cases, which is extremely advantageous in terms of storage and transportation. It is.

Moreover, when the device according to the present invention is used, two vertically symmetrical
It has the advantage of being able to efficiently manufacture several sheets of flat mesh at the same time.
