BIBS SEAL FOR CONVEYOR.
The invention relates to a flap sealers conveyor shaped trough.
It also relates to conveyor equipped with the so-called flap.
For transporting heavy materials from one place to another place, it is known to
use a conveyor belt.
The conveyor belt has a section shaped trough so that the band marrying this
trough forms a chute able to contain the bulk material.
They are known more particularly such a conveyor section which is defined by a
roll of horizontal curves and walls so-called guidance located on both sides of
The belt sliding on the walls of guidance.
The belt extends over only a portion of the wall of guidance it may have a
slight transverse movement.
The heavy material is deposited in the central part of the trough but sometimes
under the influence of speed this material is spread more or less able to move
beyond the lateral edges of the band or where the flow load is too large
compared to the linear speed of the strip. This phenomenon appears mainly
at the time of loading by gravity. To avoid the heavy material can fit between
the belt and the surface guidance affecting the operation of conveyor, a flap
seal hangs high in part, on the inside of the wall guide covers the Top of the
In theory the level of heavy material can reach the top of the bib.
At the level of recovery by sealing the flap, the belt glides thus between the
wall and guide the lower side said the flap seal.
Because of friction, there is wear the skirt seal and therefore change the flap
These bibs seals are usually either means of carnations with screws and nuts or
by a jaw of a clamp applying the upper edge of the flap on the wall of guidance.
The jaw is applied by clamping screws.
These swaps the flap are long and tedious.
It also includes the handling of the screws is made more difficult because
of dust accumulating on the threads of screws or corrosion related to the nature
or the humidity of these heavy materials. It has a bib external EP 462 847
mounted with a dovetail. Such an assembly is mounted sliding as stated in the
document mounting U.S.
We know U.S. 3344909 with a flap in the vé top wings in forming a male
part, from engaging in misrepresentation of the male female in a room which
should be widely opened to engage the wings of the male 'one after another. The
conveyor is not fit to transport bulk materials. The same is true for the device
DE 299 18 166.
If so, dust accumulates in the room female hence the need to remove the dust
before replacing the flap. The invention provides a solution that facilitates
assembly and disassembly of these bibs for transporters of bulk material and
which does not require extensive cleaning before replacing the flap.
To this end, the invention for a flap sealing including a fixation on a wall
called guidance of a conveyor heavy, medium-fixing is a means by locking elastic
deformation of one of two fractions dialing said fixing means, this flap is
characterized in that the fraction component said means fixing the flap is a
female that is distorted to come gird the male carried by the conveyor. The
invention will be well understood using the following description made as an
example not limited in terms of the schematic design represents a cross-section
of a conveyor equipped with a flap in the art.
This conveyor includes ways for the belt which the team takes a trough or chute
sure to contain the heavy material.
In the example represented in the form trough is defined by a roll 2 axis
horizontal box by walls 3 of guiding curves.
The bottom of the endless band 4 relies on the roll and glide on the lower
walls guidance. A flap 5 of sealing is mounted on each wall guidance clinging
top and bottom of this flap sealing covers the lateral edge 4 A band without
To kept on the conveyor, the flap 5 includes a fraction 6A an additional 6 of
fixing another portion 6B presented by the conveyor including 3 of the wall
The average 6 of fixing the flap is a locking by elastic deformation of a 6A of
the two fractions 6A, 6B dialing said through fixation.
The fraction 6A dialing said through fixing worn by the flap is a female that is
distorted to come gird the male carried by the conveyor. That fraction closer
surrounds the male 6B so that when the withdrawal of the flap, another flap can
be installed immediately on the Maie without the need to clean the male part.
There can be no accumulation of material between the female and male.
More specifically, the wall bears a guide 6B longitudinal ridge that runs
parallel to the upper edge and the flap has a throat open 6A whose lips 6C can
resiliently aside temporarily to the throat that covers the rim.
On the opening up of the throat against the seam, pressing with the hands, lips
and back then depart in place.
When the throat (female) is placed on the flange (male), lips 6C of the gorge
surround the rim and prevent the bib from sliding along the seam.
The flange will be, preferably, circular cross section.
Throat, ie the female part, is produced by extrusion with the rest of the flap.
At this female part, we will stiffen the said party 6A or by increasing the
thickness either locally using local material which is chosen to be less
flexible than the party will rely on the tape endlessly.
Indeed, it is necessary that the party support on mudflap in the endless band is
relatively flexible to fit the curve while the "clip" well hung.
It may appeal to the coextrusion to form this flap.
Where the wall guide is rigid plastic, it can extradite the rim at the same time
as the guide wall. It understands that to engage the female part, just a simple
gesture of pushing the hand.
To reduce dust, a lid 7 is scheduled on the conveyor in order to form a tubular
volume. So remarkable, 10 above the edge of the flap 5 of sealing at least one
lip 10A side up to be leaning on the face 7a underside of the lid 7 closing the
conveyor. It reduces the possibilities that the substance seeps behind the flap
and escapes to the outside.
This also prevents eyelash material coming creep between the flap and the side
The way to "click in" female is thus increased by the back of the bib.
The flap can be quickly replaced when necessary and without using tools.
It was therefore found a simple solution to exchange bibs.
The rim worn by the wall of guidance may be obtained or reported in the
manufacture of the wall.
