Description
A LINK FOR A CONVEYOR CHAIN, A CONVEYOR CHAIN MADE UP OF SAID
LINKS AND A METHOD OF OPERATION OF SAID CONVEYOR CHAIN
This ion relates to a link for a conveyor chain, which is adapted to be
onnected to form yor chain.
ul More particularly, this invention relates. to a unique inventive conveyor chain link,
which when interconnected and used within a conveyor system, is able to
significantly reduce frictional forces between engaging components, which not
only leads to reduced wear and tear of respective parts making up the
arrangement, but allows for the use of a significantly less power g motor.
DISCUSSION OF THE PRIOR ART
During a conventional ion of a conveyor chain or belt, it is normally
supported with an assembly structure wherein the conveyor chain is made up of a
plurality of pivbtally interconnected chain links that through a drive mechanism is
able to move in both fon/vard and reverse directions.
The person skilled in the art will realise that conveyor chains and belts have
become particularly sophisticated these days, being required not only to transport
product horizontally, but often there is now the requirement to also introduce
significant inclination and ure into the l structure of the conveyor
assembly, so that the conveyor chain can pass around various plant equipment,
handling locations, operational points inside an industrial workplace and helical
framework to be elevated or lowered to a respective level.
With such stress of design being placed upon the modern day conveyor chain
arrangement, there is the requirement to have an effective guide mechanism so
that the actual ng plate of the chain can be rolled in its preferred direction.
For the most part, this means that the conveyor chain or belt is g along a
"wear strip during conveyor movement. The resistance experienced by the chain in
conveyor movement is often the result of frictional forces between the link and the
' 2 ‘
wear strip face and edge upon the guides and/or support for the conveyor chain,
along with frictional forces against radial-directed guide surfaces at bends and at
curvature points along the length of the conveyor assembly.
Not only are there the frictional forces acting upon the engaging es, which
requires forces to be overcome, notably in the application of motors with higher
power ratings, there is also the sfactory wear and tear n the relevant
components, which the person skilled in the art will appreciate often causes
production to be suspended for various maintenance and ements of parts.
Therefore, any apparatus, means or method in which a ion in frictional
contact forces and the associated wear and tear between the components of the
moving parts of the conveyor system would be most welcomed.
Therefore, it is an object of this invention to provide an improved conveyor chain
link, which is adapted to be interconnected with other such similar links in order to
provide a conveyor chain, which when in operation upon a conveyor support
1'5 assembly, there will be significant reductions in the frictional forces between the
conveyor link and the various wear strips and/or conveyor beds supporting the
conveyor chain, resulting in the requirement for reduced operating power
ption of such conveyor chains and also significant improvement in the
wear and tear of such conveyor chain that would be othen/vise expected from a
able conveyor chain, which should advantageously lead to reduced
maintenance and ement of parts associated with the chain.
Further objects and advantages will become apparent from the complete reading
of this specification.
SUMMARY OF THE INVENTION
In one form of the ion, there is provided a conveyor chain link adapted to be
interconnected with other such links forming a conveyor chain, said link including:
" 3 '
‘ a main body,
a top plate to which a handling product or part thereof is restable
thereupon;
said main body having a front portion and a rear portion;
said front portion and rear portion having means to be interconnected such
that one link can be connectable to another in order for the establishment
of a multi-linked conveyor chain;
a first guide member arrangement including a pair of rotably-supported
laterally extending on opposing sides of an underneath side of said top
plate, adapted to roll in the direction of movement of said conveyor chain,
wherein said rollers of the first guide member arrangement are adapted to
rest and rotate along a corresponding top face of a wear strip as part of a
conveyor assembly support structure for the conveyor chain;
a second guide member arrangement, including two y-supportable
guide members on opposing sides of said main body, rotably about a
longitudinal axis, perpendicular to the top plate, wherein the peripheral
edge of the respective guide members are adapted to engage a side edge
of a wear strip face of the conveyor support assembly or a similar such
ured structure arrangement of said conveyor support assembly;
a third guide member arrangement, including a roller member adapted to
rest and rotate upon a or bed and/or wear strip of the conveyor
assembly support or other r structure of the conveyor support
assembly, wherein said roller of the third guide member ement is
laterally bly-supported by an axis ntially in parallel to the top
plate;
such that the first, second and third guide member arrangements can work
independently or in combination to reduce frictional force between the
‘ 4 "
contact positions of the cOnVeyor Chain with the conveyor chain support
assembly, resulting in a d level of power required to drive the
conveyor chain upon the conveyor support assembly during ion,
along with reduced wear and tear of the link against the conveyor support
assembly.
An advantage of such an arrangement is that rather than utilising traditional
means in order to support and guide a conveyor chain within a conveyor suppOrt
assembly for the use of sliding upon a wear strip face and so forth, in this
invention three purposely-configured guide member ements have been
"introduced in order to eliminate a sliding interaction n the relevant
components to be replaced by rotatable roller movement, thereby icantly
reducing frictional forces upon engaging parts, which means less power is
ed to drive the conveyor chain’s motion and also as wear and tear has been
significantly reduced as parts are no longer sliding against one r, but
h the use of the rollers are able to roll past without significant friction,
means that the actual down time during the use of such a conveyor chain
ion is significantly reduced.
In preference, the first guide member arrangement including the pair of rotatably-
supported rollers are of a cylindrical configuration.
In ence, the size of cylindrical rollers is comparable to the dimensions of the
wear strip, which forms part of the conveyor chain support assembly, to which the
pair of rollers of the first guide member arrangement will rest thereupon.
ln preference, each of the cylindrical rollers is rotatably-supported in defined slots
located on the underside top fonrvard corners of the top plate of the conveyor link.
An advantage of such an arrangement is that by introducing slots into the link, the
respective cylindrical rollers can be safely housed, partially inside with the
protruding portion of the cylindrical rollers then being able to fully rotate and move
along the wear strip face during conveyor movement, but keeping the chain itself
" 5 '
in close proximity to the conveyor t assembly so no gaps of significance are
created.
In preference, the cylindrical rollers may be made of plastic, steel or of a suitable
bearing arrangement or material.
In preference, the second guide member arrangement, including the 'two rollers
positioned on the respective sides of the t section, to which the top plate
rest thereupon, are of a ntial wheel orcastor uration.
In preference, each wheel is rotatable about a longitudinal axis, such that the
peripheral edge of the wheel can engage sideon with the corresponding wear strip
and/or guide of the conveyor t assembly.
In preference, the breadth or thickness of the wheel or castor of the roller for the
second guide member arrangement is of a dimension relative to the degree of
control ed during curvature or rotating movement of the conveyor chain
during operation.
In preference, the top plate support section includes two slots located centrally to
the front and rear portions of the top plate support sections for the conveyor link",
n the external slots in this central position of the top plate support section _
on respective sides allows a portion of each of the wheels or castors to protrude
therefrom.
An advantage of such an arrangement is that, just like the rollers with first guide
member arrangement, these wheels or s can be conveniently housed inside
the link, from the main body portion responsible for supporting the top plate.
In preference, the roller for the third guide member arrangement is a wheel or
castor.
" 6 '
ln preference, the wheel or castor is supported upon a moveable lateral axis so
that the link, when interconnected from a conveyor chain is adapted to turn and
rotate around as required.
In preference, the top plate includes an upper surface, wherein one side across
the breadth of the top plate is at a higher elevation.
ln preference, there is a central fold or incline n a dividable side of the top
plate.
In preference, the divide is an incline wherein one side is raised higher or lower
relative to the other.
In preference, the top plate has a lower fonNard side ion relative to the back
or rear side of the top plate.
Advantageously, by having the introduction of the incline fold dividing the top plate
into upper and lower decks means that an adjacent interconnecting link can have
its raised upper deck rest or be positioned substantially above or upon the lower
deck of the fonivard side of the top plate of an adjacent link.
Advantageously, this unique arrangement allows for pping of the links
during turning and bending when any general curvature nt of the
conveyor chain is required as it makes its way throughout its required material
handling direction upon the supporting conveyor chain assembly.
in preference, the main body top plate t section front end includes a closed-
off slot, to which a rod can pass through to rotatably support the guide wheel of
the third guide member ement, wherein the lateral configured slot will allow
the wheel or castor to turn as required during curvature movement of the conveyor
chain during operation.
In preference, the rod insertable into the lateral slot of the front n of the main
, body top plate support section at its external distal ends is also adapted to rest
" 7 ' 2012/000099
and being enclosed in corresponding chambers that protrude out from respective
sides at the rear portion of the main body of the top plate support section.
Advantageously, the interconnection means of ng multiple links er can
act as the rotational axis support for the guide wheel that is formed as part of the
third guide member arrangement, but at the same time utilise the distal ends of
this rod to be positioned within the rear portion of the main body, which is
supporting the top plate in an adjacent link.
In order now to describe the invention in greater detail, a series of illustrations and
preferred embodiments will be presented herewith.

The link 1 includes a top plate,>shown generally as 20, which is divided into a front
portion 22 and a rear portion .21, wherein the respective front and rear portions are
elevated differentially by the inclined or fold 23.
As is can be envisaged, the elevation differences between the d or front
side 22 and the rear or back side 21, brought about by the inclined 23 means that
an adjacent link can have the raised rear or back side or portion 21 positionable
over or upon the lowered forward side 22, so that during times of curvature
movement of the conveyor chain upon a conveyor support assembly, there will be
an allowed degree of rotation, which as partially shown in Figure 4, can lead to a
continual rotation of a complete 360 degrees for a conveyor chain made of such
1’5 interconnecting links working its way up an helical structure.
The top plate 20 is supported by a main body support section, shown lly as
24, which includes a front portion 25 and a rear portion 26 and a central portion
17. ~
The front portion 25 includes a lateral slot 11, to which rod 8 can pass through in
order to act as a ble t for guide wheel 7.
The guide wheel '7, as seen in Figure 6, is adapted to move along the conveyor
support ly 10, bed 18.
The central portion 17 of the main body support section 24 of the link 1 also
includes two lateral slots 13, on either side of the central portion 17, to which
rotatably supported n by virtue of rotatably pivot pins 5 are guide rollers 4,
which as best seen in Figure 6, are adapted to engage the side section 16 of the
wear strips 12, which are included as part of the conveyor support assembly.
" 9 "
The guide wheels or rollers 4, have significant importance when the conveyor is
involved in curvature turns hout the length of the conveyor support
assembly.
The underside 29 of the top plate 20 in substantial forward corners, include rollers
2, which are cylindrical-type rollers, which are rotatably-supported by rods 3,
which are oned inside respective slots 31 within the underside 29 of the top
plate 20.
As per seen in Figure 6, these cylindrical rollers 2 are adapted to roll along and
engage the upper e 14 of the wear strip 12 as the conveyor chain makes its
way across the structured conveyor support assembly.
The rear portion 26 of the main body support frame 24 for the top plate 20 has two
prongs or fingers 27, where extending therefrom are barrels or chambers 15,
which are able to interconnect an nt link by containing a corresponding rod
8, which is supporting the front guide wheel 7 upon the conveyor bed 18.
