Definitions
- the present invention relates to a conveyor system. More particularly, in one aspect it relates to a conveyor system which may be hinged to have a variably angled section to elevate or depress the direction of travel of the conveyor over a portion of it's length, and in which movement about the hinge is possible without the need for stopping the conveyor.
- the invention relates more particularly to a conveyor system in which a modular link conveyor belt, as described above, may be more easily removed from the system either in case of damage or in case its length needs to be changed.
- a replacement belt or a new belt may also be added more easily to the system.
- the invention relates more particularly to a system in which modular conveyor belts, guided and supported along their length by channels in opposed side surfaces of the conveyor belt run may be allowed a degree of freedom in terms of their overall length.
- the conveyor belt may be angled along the full length of its run, so that its upper return at a delivery point is at a higher level than its loading point.
- two or more conveyor belts may be used with goods debouching from one onto a subsequent belt, with at least one of them being angled upwardly.
- a conveyor system which overcomes or obviates the above disadvantages.
- the link between adjacent transverse slats or a slat may break or become damaged so that it is necessary to extract the belt from the system for repair or exchange
- It may also be necessary to lengthen the belt by adding additional slats or shorten the belt by removing some of the slats In existing conveyor systems, this is not easily possible without dismantling at least part of the system
- a further disadvantage of such modular link conveyor belts is that the spacing between adjacent slats may vary, albeit slightly, but over a number of slats this may be perceptible In the less common case of conveyor belt length shortening, breakage is almost inevitable In the case of lengthening of the conveyor belt, the channels in opposed side surfaces of the conveyor belt run are unable to accommodate the increased length and again problems are caused
- a conveyor system comprising a conveyor surface, at least two pairs of support member sections the members of each pair being disposed on opposite sides of the conveyor, each support member section having channel means to accommodate a respective edge of the conveyor surface, each of a first pair of support member sections having a convexly curved end and a pivot point, each of a second pair of support member sections having a concavely curved end, said second pair of sections being adapted to pivot about said pair of pivot points, said channel means adjacent said convex ends of said first sections being so divergent as to allow connection with said channel means adjacent to said concave ends of said second sections when said second sections are pivoted with their longitudinal axis at an angle of between 0° and 45° with respect to the longitudinal axis of said first sections
- the preferred maximum angle is in region of 40°
- the system may further comprise additional pairs of support member sections adapted to be connected one to the next to extend the length of the conveyor system, with an end one of said pairs of extender sections being connectable to said first pair of support member sections and/or optionally an end one of a second set of pairs of extender sections being connectable to said second pair of support member sections.
- Each section is preferably provided with two channels, one for the forward run of the conveyor surface and one for its return run.
- At least some of the sections adapted to receive a return run of the conveyor surface may be widened over a portion of their length to accommodate slack, i.e excess length, in the conveyor belt.
- the first pair of support member sections have each channel divergent to an angle similar to that of the other channel.
- the second pair of support member sections, or extender sections affixed thereto, may be supported by lift means, which may be hydraulically or pneumatically operable.
- a conveyor system comprising a conveyor surface, at least one pair of support member sections, the member sections of said pair being disposed on opposite sides of the conveyor surface, at least one pair of support member sections having channel means to accommodate respective edges of the conveyor surface, said channel means including a continuous section and a branch channel connecting said continuous section with edges of said pair of support member sections
- the pair of support member sections including a branch channel are adapted to be disposed at an end of a conveyor system
- said pair of support member sections may also include bearing means for a driving or guide wheel
- each branch channel may be adapted to connect with a channel for cooperating with the conveyor surface over a forward part of its run and with a channel for cooperating with the conveyor surface over a return part of its run
- the branch channel is, in this case, divergent to connect smoothly with each of the channels of the section
- a conveyor system comprising a conveyor surface, at least one pair of support member sections, the member sections of said pair being disposed on opposite sides of the conveyor surface and each being provided with channel means to accommodate the respective edge of the conveyor surface on both forward and return runs through the membei section, wherein the channel means adapted to accommodate a respective edge of a conveyor surface on its return run has a width, over at least a portion of its length, greater than the width of the edge of the conveyor surface or of the slats forming said surface
- a conveyor system comprising a plurality of pairs of support member sections, each pair being joinable to an adjacent pair wherein an end of each support member section is provided with a pan of pockets each adapted to receive a portion of a fastening means
- the pockets of support membei sections adjacent a join are so aligned that the portion of a fastening means held in one pocket can be joined to another portion of the fastening means held in the pocket of the adjacent member section
- the fastening means comprises a nut and bolt
- the pockets are disposed to be open to the surface of the support member section which is adapted to face the conveyor surface
- Cover means may be provided for each pocket
- each end of each support member section is provided with an alignment recess spaced a predetermined distance from each channel means and optionally also a predetermined distance from each pocket
- the system may comprise, in this case, an alignment peg which is a friction fit in two co- extending alignment recesses
- FIG. 1 is a perspective view of a conveyor system embodying the invention
- Figure 2A is a side elevation, from the side adapted to face a conveyor surface, of a first support member section,
- Figure 2B is a side elevation of a second section, shown aligned with but separate from the first section of Figure 2a,
- Figure 3 is a side elevation of a connecting piece for joining the first and second sections shown above, Figures 4A and 4B show first and second sections in aligned but separated condition, and at a maximum angle of relative inclination;
- Figure 5 is an end elevation of a support member section.
- Figure 6 is a side elevation of an end support member section
- Figure 7 is a side elevation of an end support member section having a branch channel for exchanging conveyor supports
- Figure 8 is a side elevation of an extension support member section
- the system comprises a conveyor belt 1 of the modular linked type, which comprises a plurality of transversely extending units or slats 2, each flexibly connected to adjacent ones
- the system over a major part of the length of the conveyor belt run, is bounded on opposed sides by pairs of support member sections 3, usually but not necessarily of equal length and each connectable to adjacent sections by means of nuts and bolts connected longitudinally with their ends within respective pockets 4 of the internally facing walls of the sections 3
- each support member section 3 there is provided an alignment recess 8 towards the interior of the system
- Each section 3 is provided with a pair of channels extending longitudinally of the section 3 and spaced one from the other
- An upper, in use, one of the channels 5 is adapted to accommodate, support and guide an upper edge of the conveyor surface 1 on its forward journey.
- a lower channel 6 is adapted to accommodate, support and guide a lower section of the conveyor surface on its return run. This lower channel 6 may be provided at intervals with sections of increased width 16 so that slack in the conveyor surface 1 may be taken up into such widened sections 16 of the channel 6.
- These channels 5 and 6 are however continuous when adjacent sections 3 of the side support members are connected together.
- the ends of the channels 5 and 6 are chamfered to minimise any danger of the conveyor belt catching on an imperfectly aligned edge of a channel.
- the channels should not be misaligned since each is a predetermined distance from the alignment recess 8.
- an alignment dowel (not shown) is inserted into two co-extending alignment recesses, one on each section 3. Once the alignment recesses 8 are aligned in this manner, the channels 5 and 6 will be aligned, as will the pockets 4 and the holes 4a extending from them toward the pocket of an adjacent section.
- an extension section 3 is connected to a return section 7 in which the upper 5 and lower 6 channels are connected together by a semi circular channel 11 centred about a bearing point 10.
- a motor can be connected to power a drive roller (not shown), rotatable in the bearing point 10.
- a guide roller may be provided, rotatable within the bearing point 10.
- a return section 7 is provided with a semi circular channel 1 1 to join upper channel 5 and lower channel 6 around the bearing point 10.
- the conveyor links 2 pass from the lower channel 6 to the upper channel via the semi-circular channel 1 1
- the belt will need to be withdrawn for changeover and this may be accomplished by directing an end (once the belt has been split) into branch channel 9 which extends from the semi circular channel 11 to an outside face of the return section 7
- branch channel 9 is provided in the end pair's opposite return section 7
- the branch channel 9 can cooperate with either the upper channel 5 or the lower channel 6 without undue flexing of the belt being withdrawn or inserted.
- a first end 12 of the conveyor system is disposed to be substantially horizontal in use and this end section 12 leads to a second end 13 which is supported at one of its ends by the first end 12 and near the other of its ends by means of a hydraulic or pneumatic ram 21
- the second end 13 is so hinged to the first end 12 at its one end that its angle of inclination can be changed by means of varying the pressure in the hydraulic or pneumatic ram 21 at any time, even during operation of a conveyor system
- Such variable adjustment is achieved by means of co-operating end sections of the first and second parts of the conveyor system
- the first, substantially horizontal, part 12 of the conveyor system is provided at its end with a convexly curved section 14 (see particularly Figures 2 A and 4A)
- the second part 13 of the conveyor system is provided at its corresponding end with a concavely curved end section 15 (see particularly Figures 2B and 4B)
- a connecting plate 17 attached to the internal face of each of the pair of second concavely curved end members I S
- the channel sections 5 and 6 of the first convexly curved end member 14 diverge at their ends adjacent to the convex end to the face
- the maximum angle of inclination is preferably 40°, although angles of up to 45° can be contemplated withm the present invention
- the lower, in use, edge of each of the channels 5 and 6 remains substantially horizontal (see Figures 2 A and 2B), while the upper edge of the channels diverges through an arc until the tangent is at the maximum angle of 40° or 45°
- An end section, adjacent to the convexly curved end face is sufficiently straight to align with channels 5 and 6 of the second end section 15 when that is at its maximum angle with respect to the general axis of the first section (see Figures 4A and 4B)
- the channels 5 and 6 of the second end section 15 will align with the respective channels 5 and 6 of the first end section 14, at a point between the top and bottom edges thereof
- the conveyor surface 2 will be unsupported and not guided other than to be maintained within the maximum limits set by the divergence of the channels 5 and 6 of the first end section 14
- the present invention allows the conveyor system to be variably angled, if necessary during use of the conveyor system
