[0001] The present invention relates to a roller cage for a profiling line according to
the preamble of claim 1 (see for example
EP-A-1 985 387).
[0002] A profiling machine comprises substantially a series of cages, arranged in succession,
each of which comprises at least two profiling rollers. These cages are configured
for progressively bending a strip of steel around a longitudinal axis until they confer
thereon a desired cross section, which may for example be square, rectangular or another
shape. The bending of the sheet is performed by passing the sheet itself between the
rollers of various cages which, by contact, progressively deform it. The strip slides
continuously through the cages, being progressively deformed.
[0003] The rollers of each cage are mounted on rotating shafts which are connected to uprights,
also known as shoulders, which, in turn, are fixed onto a base. This base is arranged
on a fixed bed to which it is removably constrained and/or transversally adjustable.
[0004] Each profile to be produced requires a series of transverse rollers whose characteristics
are determined by the shape and dimensions of the profile itself.
[0005] At each change of production, it is necessary to carry out a partial or total replacement
of the entire series of transverse rollers in the various cages. This operation, which
must be carried out with the line stopped, requires considerable time for its execution.
[0006] Roller cages according to current technology have two uprights or shoulders, with
which the cage rollers are associated. The cage rollers are substantially positioned
in the space comprised between the two shoulders. On one side of the cage, i.e. next
to one of the two shoulders, the motor unit of the cage is positioned, comprising
one or more motors, one or two reducers and one or two Cardan joints, for the activation
in rotation of at least two cage rollers. The shoulder on the motor unit side is normally
fixed. The other shoulder of the cage, positioned on the opposite side of the motor
unit, is removable, for allowing access to the rollers and to the other components
of the cage and also for allowing changes, either in case of maintenance, or in case
of changing the format of the product to be produced. To change the tools of the cage,
it is necessary to remove the movable shoulder, take out the tools to be replaced
and mount those intended for the new production. Over time quick change methods have
been developed that envisage the off-line replacement of whole plates equipped with
cages. In this way, the equipment can be changed off line during production downtime.
[0007] The currently available roller cages have several drawbacks.
[0008] First of all, it is necessary to double the supply of cages, so as to always have
one available in line and one off line. This implies a clear cost burden.
[0009] It is also necessary to provide very large spaces for positioning the cages off line
and performing the equipment change.
[0010] A further drawback is represented by the dangerousness of moving the mounted cages
which can reach the weight of 15-20 tonnes, with the use of bridge cranes.
[0011] Consider also that the technology currently available on the market envisages, for
every cage, in the simplest case, a power transmission to the motor rollers through
flanges, Cardan joints, a distributor per cage, a gearbox and an electric motor. For
example, a section of the line for the calibration of the profile, provided with four
cages, requires an electric motor, a reducer, a gearbox, four distributors (for distributing
power to the four cages) and eight Cardan joints (two per cage) with the related coupling
flanges.
[0012] Alternatively, more evolved solutions envisage an electric motor per cage, a distributor
with a gearbox per cage, two Cardan joints with the related coupling flanges per cage.
[0013] Both solutions therefore require a lot of space on the motor unit side, and therefore
have very low performance levels. Much of the energy developed by the electric motors
is in fact consumed just for rotationally driving the transmission, with consequent
losses due to the effect of the couplings between the gears of the reducers, for the
rolling of the bearings, due to the movement of oil, etc.
[0014] The aim of the present invention is to provide a roller cage for a profiling line
which allows the drawbacks of the currently available machines to be obviated. The
roller cage according to the present invention is defined in claim 1. Moreover a profiling
line comprising a plurality of roller cages according to the present invention is
defined in claim 11. The dependent claims define preferred embodiments of the present
invention.
[0015] An advantage of the roller cage according to the present invention is that of being
much more compact than the cages currently available.
[0016] Another advantage of the roller cage according to the present invention is that it
notably facilitates access to the transverse rollers, as well as all the maintenance
and/or replacement operations.
[0017] A further advantage of the roller cage according to the present invention is that
it does not require the use of reducers or other transmission members, allowing a
remarkable saving on costs and a consistent reduction of power dispersions.
[0018] Further characteristics and advantages of the present invention will become more
apparent in the following detailed description of an embodiment of the present invention,
illustrated by way of example in the attached figures, in which:
- figure 1 shows a view of a cage according to a preferred embodiment of the present
invention,
in a first operating configuration;
- figure 2 shows a view of a cage according to a preferred embodiment of the present
invention,
in a second operating configuration;
- figures 3 to 7 show different operating steps of a sequence of operations for the
automatic change of two transverse rollers (33,43).
[0019] A profiling line (figures 3-7) comprises a plurality of roller cages (G), arranged
in succession along a longitudinal direction (Y) which is also the advancement direction
of the profile being processed. As is known, roller cages are configured and suitably
sized for progressively bending the starting steel strip around the longitudinal axis
(Y), until a tubular conformation is conferred thereto. The bending of the starting
strip takes place through the passage of the strip itself between the rollers of the
various cages which, by contact, progressively produce the deformation thereof. In
other words, the strip slides continuously through the roller cages, being progressively
deformed. Downstream of the roller cages (G) a welding device is normally provided
(not illustrated) which joins the longitudinally neared edges of the starting strip.
[0020] As shown in figures 1 and 2, the roller cage according to a preferred embodiment
of the present invention comprises a support frame (F1) placed in a non-operating
space external to the line, i.e. a space inside which the profile does not transit
and no processing is performed on the profile. The support frame (F1) comprises, for
example, two shoulders (S1, S2), i.e. two load-bearing structures that extend substantially
on a vertical plane. These shoulders (S1, S2) are associated inferiorly with a base
(D) and superiorly with a transverse structure (T). The position of the frame (F1),
in its entirety, can be regulated transversally to the longitudinal direction (Y).
[0021] The cage comprises a motor (not shown) associated with the frame (F1) and a spindle
(12) that projects externally to the non-operating space. In a preferred, but not
exclusive, embodiment, the spindle (12) projects in a cantilever fashion from the
motor (11), i.e. it is sustained by the motor (11) alone and has a free end that is
not sustained by other structural parts. In this preferred solution, the motor is
preferably a torque type motor, as will be better explained in the following description.
In a possible solution, the spindle (12) is associated with the motor through a transmission
of the known type, which comprises, for example, a reducer and one or more Cardan
joints and one or more transmission shafts.
[0022] A transverse roller (13) is assembled directly on the spindle (12) and arranged inside
an operating space of the line, i.e. the space within which the profile transits for
undergoing the processing by the transverse roller (13). The operating space is substantially
arranged next to the frame (F1), externally to a shoulder (S1) of the frame (F1) itself.
In substance, the transverse roller (13) is not arranged between the shoulders (S1,
S2) of the frame (F1), but on the external side of a shoulder (S1), on the opposite
side with respect to the other shoulder (S2), projecting externally to the frame (F1).
[0023] Thanks to the structure of the cage according to the present invention, the transverse
roller (13) is cantilevered or projecting externally to the support frame (F1). The
transverse roller (13) faces outwards, in the operator's view, without obstacles or
other front parts. The remarkable ease with which it is possible to access the transverse
roller (13) if necessary is therefore absolutely clear, for example, for maintenance
operations or disassembly and replacement operations.
[0024] Furthermore, the direct mounting of the transverse roller (13) on the spindle (12)
allows to avoid the use of reducers and other transmission members. This implies a
remarkable reduction in system costs and energy losses, as well as a considerable
reduction in the space required.
[0025] Advantageously, the cage according to the invention may be provided with a second
motor (not shown) associated with a spindle (22) that projects externally to the operating
space. Also in this case, in a preferred, but not exclusive, embodiment, the second
spindle (22) projects in a cantilever fashion from the second motor (21), i.e. it
is sustained by the motor (21) alone and has a free end that is not sustained by other
structural parts. In this preferred solution, the motor is preferably a torque type
motor, as will be better explained in the following description. It would be possible,
however, to associate the spindle (12) with the motor through a transmission of the
known type, which comprises, for example, a reducer and one or more Cardan joints
and one or more transmission shafts.
[0026] A second transverse roller (23) may be mounted directly on the spindle (22) of the
second motor (21). The second transverse roller (23) is also arranged in the operating
space of the line, next to the frame (F1), externally to a shoulder (S1) of the frame
(F1) itself. The second transverse roller (23) is also not arranged between the shoulders
(S1, S2) of the frame (F1), but on the external side of a shoulder (S1), on the opposite
side with respect to the other shoulder (S2), projecting externally to the frame (F1),
and is therefore easily accessible as the first roller (13) is.
[0027] The direct coupling between each transverse roller and the respective spindle allows
to avoid the use of reducers, joints and other transmissions which, as well as increasing
the costs of the cage, produce a significant reduction in the mechanical performance
of the cage itself.
[0028] The two transverse rollers (12,23) may be arranged in a vertically opposing position,
as shown in figure 1, or could be offset from one another. Preferably, they are arranged
one above and the other below the profile being processed. For the second transverse
roller (23) the same advantages already described for the first transverse roller
(13) are valid, in terms of direct accessibility and ease of maintenance or replacement.
The direct coupling of the second transverse roller (23) to its spindle (22) allows
to avoid the use of a reducer and other transmission members, with the advantages
already described above, without increasing the overall space occupied by the cage.
[0029] In the embodiment represented, the spindles (12,22) of the two motors (11,21) are
substantially parallel to one another. Furthermore, the axes of rotation of the two
spindles (12,22) lie on the same vertical plane. The motors (11,21) are substantially
parallel to one another, to allow the overall dimensions required by the two motors
to be reduced. This does not exclude the possibility that, for particular construction
or positioning requirements, the two motors and the two spindles could be arranged
differently from what is illustrated in figure 1.
[0030] The cage according to the present invention comprises a movable frame (F2), with
which a first upright roller (33) is associated, rotating about a first shaft (32).
Such first shaft (32) projects in a cantilever fashion from the movable frame (F2).
[0031] The movable frame (F2) is movable between an operating position (figure 1), in which
the first shaft (32) assumes a substantially vertical position, and a non-operating
position (figure 2), in which the first shaft (32) assumes a substantially horizontal
position and is facing the same way as the first spindle (12) and the second spindle
(22), towards the operating space of the line.
[0032] In the operating position of the movable frame (F2) the upright roller (33) is arranged
with a substantially vertical axis of rotation, or an axis of rotation slightly inclined
with respect to the vertical direction, so as to come into contact with a side of
the profile being processed. Preferably, but not necessarily, the shaft (32) projects
upwards towards the top of the movable frame (F2). In a possible alternative embodiment,
the shaft (32) could project downwards from the movable frame (F2). In that case,
the movable frame (F2) would be arranged in a higher position with respect to the
one shown.
[0033] In the non-operating position of the movable frame (F2), the shaft (32) projects
in a cantilever fashion from the movable frame (F2) and is arranged in a substantially
perpendicular position to the previous one, therefore being substantially horizontal,
or slightly inclined with respect to the horizontal direction. The shaft (32) is also
facing the same side as the spindles (12,22), towards the operating space of the line,
with the movable frame (F2) instead facing towards the non-operating space of the
line, on the same side as the shoulder (S1) of the load-bearing frame (F1). In the
non-operating position of the movable frame (F2), the upright roller (33) is therefore
accessible on the same side as the transverse rollers (13,23), without any front obstacles,
since it is connected in a cantilever fashion to the movable frame (F2).
[0034] Preferably, a second upright roller (43) is associated, with the possibility to rotate,
with a second shaft (42), substantially parallel to the first shaft (32) and projecting
in a cantilever fashion from the movable frame (F2). The second upright roller (43)
is placed next to the first upright roller (33) so as to be able to be arranged, in
the operating position of the frame (F2), in contact with an opposite side of the
profile being processed. In the non-operating position of the movable frame (F2),
the second upright roller (43) is arranged in exactly the same way as the first upright
roller (33), and is equally accessible on the same side as the transverse rollers
(13,23), without any front obstacles, since it is connected in a cantilever fashion
to the movable frame (F2).
[0035] In the embodiment represented, the movable frame (F2) comprises a cross member (30)
which can rotate about an axis between the operating position (figure 1) and the non-operating
position (figure 2). The first shaft (32) and the second shaft (42) are connected
in a cantilever fashion to the cross member (30), projecting upwards from the latter,
in the operating position. The cross member (30) is connected to a base (31), in turn
connected to the base of the profiling line. In a known way not illustrated in the
figures, the position of the base (31) can be adjusted transversally to the longitudinal
direction (Y) on the base of the profiling line. The cross member (30) may rotate
with respect to the base (31) about a horizontal axis that is substantially parallel
to the longitudinal direction (Y). Preferably the shafts (32,42) are slidable on the
cross member (30) along a perpendicular direction with respect to the axis of rotation
of the cross member (30). This allows the position of the upright rollers (33,43)
to be adjusted, particularly in the operating position of the movable frame (F2),
for adapting to any changes of the profile being processed.
[0036] The movable frame (F2) is placed next to the load-bearing frame (F1).
[0037] Preferably, the position of each motor associated with the spindles (12,22) is adjustable
along a vertical direction. The vertical adjustment allows the position of the transverse
rollers to be adapted to the thickness of the sheet and/or to the dimensions or conformation
of the profile. The vertical adjustment of each motor may be obtained through guides
and actuators, known to a person skilled in the art, interposed for example between
each motor and the load-bearing frame (F1).
[0038] Preferably, the position of the transverse rollers (13,23) is adjustable along a
horizontal direction. In particular, the horizontal adjustment direction of each roller
is perpendicular to the longitudinal direction (Y) of the profiling line, for example
it coincides with or is parallel to the axis of rotation of the roller itself. The
adjustment of each transverse roller along the horizontal direction may be obtained,
for example, by adjusting the position of the respective motor, or by arranging an
adjustable coupling in the axial direction between each transverse roller (13,23)
and the related spindle (12,22). The horizontal adjustment of each motor may be obtained
through guides and actuators, known to a person skilled in the art, interposed for
example between each motor and the load-bearing frame (F1). Further, the position
of the transverse rollers (13, 23) is adjustable in the vertical direction (in a known
way not illustrated in the figure).
[0039] The horizontal adjustment of each transverse roller (13, 23) allows the position
of the transverse rollers to be adapted to the thickness of the sheet and/or to the
dimensions or conformation of the profile. Further, the horizontal adjustment of each
transverse roller (13, 23) allows the various cages arranged in succession along the
profiling line, to be aligned along a longitudinal direction of the profiling line.
In a possible configuration, the lower transverse roller (23) is fixed, while the
upper transverse roller (13) is movable horizontally for adapting to the profile of
the lower transverse roller.
[0040] To facilitate the longitudinal alignment of the various cages arranged along the
profiling line, the load-bearing frames (F1) of each cage can be equipped with a horizontal
adjustment means, that allows the position of each load-bearing frame to be adjusted
along a horizontal and perpendicular direction to the longitudinal direction (Y) of
the profiling line. Such horizontal adjustment means may, for example, comprise a
guide interposed between the base (D) of each frame (F1) and an actuator device for
controlling the sliding of the load-bearing frame along the guide. The adjustment
means is known to a person skilled in the art, therefore will not be described in
further detail.
[0041] The profiling line comprising a plurality of roller cages (G) according to the present
invention may be equipped with an automatic alignment device for aligning the transverse
rollers (13,23) with respect to the longitudinal direction (Y). In substance, the
device is configured to adjust the position of each transverse roller (13, 23) along
a horizontal direction perpendicular to the longitudinal direction (Y) and along a
vertical direction. Such regulation could be performed for example through the horizontal
and/or vertical movement of each motor, in the ways already described previously,
or in combination with the horizontal movement of the support frames (F1). The alignment
device may acquire the effective position of each transverse roller (13,23) through
an optical detector, for example through a laser detector.
[0042] Furthermore, each roller cage (G) may be equipped with a dimensional detector (not
shown), configured to detect and measure determined geometrical parameters of the
profile at the outlet of the cage (G) itself, for example a radius of curvature, the
height or width of the profile with respect to a horizontal frame and the dimensions
of the profile. Each dimensional detector may be connected to the automatic alignment
device which adjusts the position of each transverse roller according to the signal
received.
[0043] In a preferred embodiment, each motor is a brushless motor with permanent magnets.
In particular, each motor is a torque motor. As is known, the torque motor is particularly
suitable for direct coupling with the member to be rotationally driven, in this case
a transverse roller.
[0044] The cantilevered arrangement of the transverse rollers (13, 23), and the possibility
to rotate the upright rollers (33, 43) in the operating position, in which they are
turned parallel to the transverse rollers (13, 23), notably facilitates all maintenance,
disassembly and replacement operations on the rollers themselves, since the rollers
are facing towards the operator without obstacles or other front parts. In particular,
the cantilevered arrangement of the rollers (13, 23, 33, 43) allows the use of a changing
device (50), configured for replacing each roller (13,23,33,43) of the cages (G) with
another roller.
[0045] The changing device (50) comprises an operating head (51), movable in the space so
as to be able to reach each roller (13,23,33,43) of the cages (G). As can be easily
inferred from the figures, the operating head (51) has free access to all the rollers
(13, 23, 33, 43) of the various cages (G), i.e. thanks to the cantilevered arrangement
of the transverse rollers (13, 23) and to the non-operating position of the upright
rollers (33, 43), in which the latter are disposed in a cantilever fashion from the
movable frame (F2) substantially parallel to the transverse rollers (13, 23).
[0046] In order to be able to reach all the cages (G) and the related rollers, the operating
head (51) is associated with a support structure that comprises a first guide (55),
parallel to the longitudinal direction (Y). The first guide (55) is preferably positioned
above the cages (G) and is supported by the pillars solidly constrained to the base
(D) of the line. A cross member (56) is slidable along a first guide (55) in a direction
parallel to the longitudinal direction (Y). Such cross member (56) is associated with
an upright (57) with which the operating head (51) is associated. The upright (57)
is slidable along the cross member (56) according to a horizontal transverse direction
(X) perpendicular to the advancement direction (Y).
[0047] The operating head (51) is associated with the upright (57) with the possibility
to slide along a vertical direction. Preferably, but not necessarily, the operating
head (51) comprises a rotary actuator (58), configured to determine the rotation of
the operating head (51) about a vertical axis.
[0048] As can be seen in the figures, the combination of movements of the cross member (56),
the upright (57) and the operating head (51) itself along the upright (57), including
the rotation about a vertical axis, allows the operating head to reach all the rollers
of the various cages (G).
[0049] The operating head (51) is equipped with an actuator means (52) for the disassembly
and reassembly of a roller (13, 23, 33, 43) on the respective spindle or shaft. Preferably
the actuator means (52) comprises a pair of actuators substantially parallel to one
another, able to act simultaneously on two rollers. As can be seen in figures 5 and
6, thanks to its own movements, the head (51) may bring each actuator means (52) into
an aligned position with one or both of the spindles (12,22) or with one or both of
the shafts (32, 42) of a cage (G). In that position, shown in figure 5, the head (51)
brings the actuator means (52) into contact with one or both transverse rollers (13,
23) or one or both upright rollers (33, 43). In such configuration, the actuator means
(52) remove the rollers from their supports (spindle or shaft), as shown in figure
6. With a sequence of inverse movements, the head (51) is obviously able to position
a roller on a spindle (12,22) or on a shaft (32, 42).
[0050] Advantageously, the profiling line may be provided with a magazine (60) for a plurality
of rollers (R) interchangeable with the rollers (13, 23, 33, 43) of the cages (G).
The magazine (60) is located in a position that can be reached by the head (51). Preferably,
but not necessarily, the magazine (60) rotates on command about a vertical axis. This
allows each roller (R) to be facing a desired position, for facilitating the operations
of the head (51). As shown in figure 7, the head (51), through its movements, is able
to reach the magazine (60) for taking a roller (R) or releasing a roller (13,23,33,43)
taken from one of the cages (G).
[0051] In the embodiment represented, the magazine (60) comprises a plurality of support
pins (61) for supporting the rollers (G). Such pins (61) project transversally from
a central support (62), rotating about a vertical axis. Advantageously, but not necessarily,
the magazine (60) may have the possibility to slide vertically between an upper position,
in which it is reachable by the head (51), and a lower position, in which it is located
below ground level. In substance, in the lower position the magazine (60) is located
in an underground position with respect to the profiling line, without projecting
from the ground. In that position, the magazine (60) does not encumber the resting
surface of the profiling line. The magazine (60) could also be at a distance from
the profiling line, to allow, for example, the removal or replacement of the rollers
(R).
