Description
1. Description of the Patent entitled:
"AUTOMATIC BAR FEEDING DEVICE"
— O —
This invention is concerned with an automatic feeder for bars and/or
5, metal rods on machines for the production of electrowelded mesh making
plants having its particular feature to position, at a requested distance,
one or more pieces of said bars and/or rods.
Device allows unilateral continuous introduction of bars, bars are
continuous or in pieces, on their own positioning level, likewise for a
0# bilateral positioning we need to have two devices which are opposite in
position and in function.
Invention permits to build in automatic and quickly special electrowelded
meshes (with orthogonal links) having general shapes with different
geometrical shape, partial local reinforcements, empty spaces or project 25 interruption.
At technical's state of things in case of construction of irregular
electrowelded mesh construction that is on project drawing we operate manually and/or automatically on electrowelded normal mesh by cutting
parts which are to be cut off and eventually add reinforcements partially.
2Q This, besides forming a number of wastes and having a large spaces to
work, this resulted not much economic because such operations need a
long time and modifications influence on the unit price of product.
Therefore, we thought to make an automatic feeding device for bars
and/or rods continuously to be applied on welding machines for
!• electrowelded mesh, this allows to position in any point in the lateral orthogonal sense, according to the feeding sense of mesh, one or more bars of equal or different length. This way, besides avoiding staff
intervention (therefore time and cost reduction) avoiding wastes because
5- we only use the necessari bar.
As mentioned, device is driven automatically therefore is capable to operate on project drawings.
According to this invention, feeding device is composed by: a bar or
metal rod training device, automatically driven suitable to operate in both
10. senses (feeding and return); a cutting device; a sequence spaced of a
plurality of lined up guides opening by command and a plurality of levers
or carriers for the positioning under the welding device of said bars or
pieces of rods.
Mechanical combination permits to position bars or pieces in a continuous
15. or spaced mode, automatically, by acting in synchrony and or in progression
between all the parts mentioned.
As a matter of fact, supposing that straight bar used comes from the unwinding of continuous metal wire coil, function sequences (in a possible
solution) of the combination are the following: the training device,
20. bidirectional, feeds up bar of required size, through the spaced guides;
afterwards, cutting device make the cutting to measure (if of total
dimension, bar will be placed under the welding unit, if of partial dimension
it will need to be moved straight according to drawing); for the rectilinear
positioning of the piece entrainer at double rotation sense comes into action,
1. the edge of the new bar pushes forward the end of the piece by means of
special guides, gauged and elastic, until reaching the position required
and avoid any uncontrolled moving of said piece; then, entrainer inverts
rotation sense and takes the new bar while the piece of wire remains still
5. into the reached position; entrainer takes totally or partially the new bar
of said size equal to the positioning distance space between both bars;
afterwads the cutting device comes into action and cuts the bars; now,
previous phase will be more or less repeated until reaching the rectilinear
definitive positioning of bars according to drawing; in conclusion, orthogonal
10. carriers come into action automatically which move, from the opening
guides (subject to springs) to the welding device bars positioned (we will have the union of lateral bars of this invention with the longitudinal ones fed by other machines).
A first variation to this invention is concerned with the possibility to
15. adjust the dimension of diameter of bars of automatic training device and
the possibility to use opening guides, spaced, rectilinear, invertable of
the same or of different diameter and/or opening guides having more
parallel housings of a same or of different diameter.
A second variation to this invention is the possibility to make the whole
20. feeding combination moble in order to position under command the rods
or wire pieces in parallel on a construction level of mesh.
A third variation to this invention is concerned with the possibility to
use the feeding device in couple, in contrast, on the same line or on parallel
lines in order to operate for the construction of large electrowelded meshes.
1" A forth variation to this invention is concerned with the possibility to
make many electrowelded side by side meshes previously cut, as a matter
of fact feeding device can cut, push and position many rod pieces on the
same trajectory, each one of them will be part of a single electrowelded
5- mesh.
Above mentioned characteristics will be better understood and pointed
out while other will appear from the following detailed description of a-
non limited realization example, in the four attached drawings, in which:
- Fig.l shows a plan view a special electrowelded mesh, with orthogonal !0« links, shaped, with empty spaces and eventual local reiforcements according to drawing;
- Fig.2 shows a side view of bar positioning device into welding zone pointing
out movement of the carrier from release opening guide;
- Fig.3 shows a schematic front view of the training device, the cutting
15. and the guides pointing out the first work phase, to be the cut of a piece
of bar;
- Fig.4 shows a front view, as per Fig.3, the second work phase that is the
pushing of the piece of wire with the new bar through the spaced guides
until reaching requested position;
20. - Fig.5 is a front view, as per Fig.3 and 4, of the third phase that is the
call back of continuous bar leaving the piece in position;
- Fig.6 is a front view, as per Fig.3, 4 and 5, of the fourth phase consisting
in the cut to measure of the second piece of wire on the same direction
(for example x-coordinate);
1- - Fig.7 shows a front view, as per Fig.3, 4, 5 and 6, the fifth phase, that
is, the pushing of the second piece of wire with the edge of the new bar;
- Fig.8 shows a front view, as per previous Fig.3, 4, 5, 6, and 7, the sixth
phase, of call back of the new bar leaving in position the second piece of
5. wire. The following phase will be the positioning of the first and the second
piece under the welding device. Besides, the drawing points out an example
of electrowelded mesh composed by discontinuous bars and spaced in order
to form an empty space.
According to the invention and in conformity with a realization mode
10. of the automatic feeding device of bars or steel rods in a continuous mode, coming from a skein or coils, it includes an automatic entraining device
(2), adjustable in order to operate on different diameters of wire and to
push it in both directions: frontwards and backwards. Following is the
automatic cutting device (3) which cuts to measure rods of any length,
15. of maximum dimension possible for machine or partial pieces. Following
is a set of special guides (4), spaced, and elastically half-moon opening,
with two holes of different diameter for the passing of relevant steel rods.
They are interrupt and spaced to permit the action of lever or carrier (6) orthogonal to the wire feeding, these move and position wire under the
20. electrodes of the welding device (7) which will link wire (1.1 - 1.2) to the
orthogonal wire (8) already present as a mesh component.
The whole feeding device is capable to cut to measure wire (1.1 - 1.2)
and to position it at a requested distance making it pass through the holes
of the opening guides (4), through the push of the edge of rear wire (1)
. on the edge of the cutted wire (1.1). Once such position is reached entrainer calls back wire (1), leaving wire (1.1) in position, and waits for the next
cut to measure (1.2) on the same line or for a new line, positioning operation
is repeated as already described with the particularity that second piece
5# can be positioned distant from the first, on the same line, leaving space
according to drawing. After this, carries (6) come into action by moving
them under the electrodes for the effective welding.
Afterwards, cycle will be repeated following the construction of mesh
according to the drawing.
0 Mesh which may be normal or elaborated with perimetric and inner
shapings, for example empty spaces (5) local reinforcements (1.1 and 1.2).
