Definitions
- This invention is concerned with improvements in or relating t a roof tile making machine and its method of operation.
- Concrete roof tiles are in the main formed by the well know roller and slipper method in which tile pallets are fed seriati beneath the mortar hopper of a tile making machine, whereat whe the machine is in use, mortar is fed onto the pallets to form continuous ribbon thereon. Downstream of the mortar hopper, cutting mechanism of the tile making machine is operated to cu the ribbon of mortar to form discrete "green state” tiles on th individual pallets which "green state” tiles are thereafter cure by conventional means.
- the upper surfaces of the tiles so formed are generated by th roller and slipper and may therefore be of any desired profil across the tiles so formed.
- the tiles may have so-called "Bold Roll” or "Roman” profile.
- the under-surfaces of the tiles are forme by the pallets, that is, the surfaces of the pallets are shape with recesses and channels to form hanging nibs, strengthenin ribs and downwardly facing interlocking sidelock features of th tiles.
- the strengthening ribs have a depth which is self-defeatin in relation to their purposive intent which is to strengthen th tiles.
- Tests effected on cured tile sections have consistentl indicated that the thin body sections have greater strength tha the ribs, or that size for size the proportion of the tile' strength supplied by the ribs is disproportionate to their depth It is believed that this phenomenon is caused by the variations in compaction of the different sections of the tiles. For example, a thin body section is readily compacted to give a high strength for a particular cross-section and yet an adjacent strengthening rib formed under the same compacting pressures, applied by the same roller and slipper does not have the strength expected of it.
- the present invention seeks to overcome or at least mitigate the disadvantages of the prior art concrete roof tiles.
- the present invention provides a tile making machine comprising a hopper provided with a packshaft, roller and slipper, said pack- shaft being effective, when the machine is in use and tile pallets are fed seriatim beneath said hopper, to direct mortar onto said pallets as they pass beneath the roller and slipper to form a continuous ribbon of mortar on said pallets, characterised in that the tile making machine also comprises compaction means upstream of said packshaft, roller and slipper, which compaction means comprises a primary compaction device which, when the machine is in use and tile pallets are fed as aforesaid, directs and compacts mortar onto and/or into selected portions only of said pallets said selected portions forming, inter alia, longitu ⁇ dinal strengthening ribs in finished tiles.
- the present invention also provides a tile making machine accord ⁇ ing to the preceding paragraph further characterised in that said compacting means also comprises a secondary compaction device wherein, when the machine is in use, and after the primary compaction device has directed and compacted mortar onto and/or into the selected portions of the pallets as aforesaid, the secondary compaction device further compacts the mortar in said selected portions only of the pallets as the pallets pass there- beneath to fully compact the mortar of the portions forming the longitudinal strengthening ribs in the finished tile as aforesaid.
- the primary compaction device comprises a multi-tined wheel arranged in use to overlie selected portions only of said pallets as aforesaid, the multi-tined wheel con ⁇ veniently having an effective width corresponding to the width of the longitudinal strengthening ribs formed by said selected portions only of the pallets.
- the present invention also provides a tile making machine accord ⁇ ing to the last two preceding paragraphs wherein the secondary compaction device comprises a thin gauge blade element extending parallel to the direction of feed of the pallets fed seriatim beneath said hopper, the blade element comprising a blade portion arranged to lie in or towards a nip portion provided in use of the tile making machine and formed between a circumferential path generated by the tines of the multi-tined wheel and co-planar upper surface portions of said pallets fed therebeneath.
- said blade element has an effective length of 0.1 to 0.3 the length of tile pallets used therewith.
- the compaction means is located in said hopper upstream of the packshaft, roller and slipper, as aforesaid.
- the compaction means may be located in a secondary hopper located upstream of said hopper.
- the present invention also conveniently provides a process for the manufacture of concrete roof tiles in a conventional tile making machine provided with a hopper supporting a packshaft, a roller and a slipper all of known configuration, said process comprising the steps of :
- Figure 1 is a schematic side elevation of a twin hopper tile making machine provided by the invention
- Figure 2 is a schematic side elevation of a hybrid modifi ⁇ cation to the hopper arrangement shown in Figure 1;
- Figure 3 is a schematic side elevation of a unitary hopper tile making machine
- Figure 4 is an enlarged view of parts shown in Figure 1;
- Figure 5 is a view in the direction of arrow V in Figure 4.
- Figures 6 and 7 are corresponding views to Figures 4 and 5 and illustrate further modifications to the tile making machine.
- the present invention thus comprises a unique tile making machine 4 which enables a novel method of making concrete roof tiles 2 to be effected so that all sections of the tiles produced therein are subjected to uniform or substantially uniform compaction forces resulting in a uniformity of mortar density in the finished product which, when cured, has a uniform strength or substantially so.
- the tile making machine 4 see Figure 1, comprises twin hoppers 8 and 10 located in series overlying a pallet conveyor 12.
- the conveyor 12 is of conventional design, is supported on floor mounted columns 12a and 12b and comprises support rails 12c on which pallets P are supported as they pass seriatim beneath the hoppers 8 and 10.
- the hopper 8 is also of conventional design and provides support for a roller 13, a slipper 14 and a pack shaft 16.
- the hopper 10 is located upstream of the hopper 8 and comprises a shaft 18 located towards a front wall 20 thereof.
- the shaft 18 provides support for a primary compaction device comprised of two tined wheels 18a only one of which is shown in the drawings, the purpose of which tined wheels will be made clear hereinafter.
- the front wall 20 provides support for a secondary compaction device comprised of a blade element 22 the purpose of which element 22 will also be made clear hereinafter.
- each hopper 8 and 10 Located above each hopper 8 and 10 are respective material feed conveyors 34 and 36 for feeding mortar to said hoppers, see Figure 1.
- the tile making machine Downstream of the hopper 8, the tile making machine is provided with a conventional tile cutting knife 38 which is mounted for reciprocal vertical and longitudinal movement on a knife carriage 40 illustrated schematically in Figure 1.
- the tile making machine also comprises a pallet spacing conveyor 42 which is arranged beneath the conveyor 12 and adjacent the knife carriage 40 for a purpose also to be made clear herein ⁇ after.
- the recesses 19 enable the formation of the strengthening ribs of a roof tile and, as can be seen in Figure 5, the tined wheels 18a each overlie a respective one of the recesses 19, the wheels 18a each providing support for an array of tines 18b in three equi-spaced memorid ranks around the circumference of the wheel 18a.
- the blade element 22 which is between 0.1 and 0.3 the length of a tile pallet P acts in part as a conventional slipper and further compacts the mortar into the recesses 19 to facilitate the manufacture of concrete roof tiles with reinforcing ribs which are fit for purpose.
- the pallets P thereafter proceed beneath the hopper 8 whereat the mortar therein is compacted by the packshaft 16, the rollers 13 and the slipper 14 onto the pallets P and the pre-formed rein ⁇ forcing ribs to form a ribbon 46 of mortar on the pallets P in known manner.
- the ribbon 46 is thereafter cut by the knife 38 of the tile cutting arrangement whereupon trailing ends of the pallets P are engaged by drive elements 52 of the conveyor 42 whereby the "green state" tiles 2 on their associated pallets P are conveyed to racking devices prior to transportation to curing chambers.
- the tile making machine may be modified as shown in Figure 2 in which the twin hopper arrangement is replaced by a hybrid hopper 9 having first and second sections 9a and 9b corresponding to hoppers 10 and 8 respectively of Figure 1.
- the sections 9a and 9b are separated by a divider plate 9c which supports the blade element 22 at its lower end 9d, see Figure 2. All other features are essentially the same as those of Figure 1 and they have, therefore, been accorded like reference characters.
- the tile making machine may also be modified as shown in Figure 3 in which a unitary hopper 11 comprises support for the roller 13, slipper 14, packshaft 16, tined wheel 18a and the blade element 22.
- a unitary hopper 11 comprises support for the roller 13, slipper 14, packshaft 16, tined wheel 18a and the blade element 22.
- guide plates 20a and 20b may be provided on each side of the wheels 18a and 18b to direct mortar into the recesses 19 of the pallets P.
- a screw augur 60 may be provided adjacent the wall 20 as shown in Figure 6 which augur 60 feeds mortar to a collection box (not shown) for recirculation to the top of the hopper 10.
- tiles made using the three modified arrangements of Figures 1, 2 and 3 may on the one hand be comprised of different mortars or on the other hand be of the same mortar throughout their thicknesses.
- the mortar delivered by conveyor 36 to the hopper 10 or the section 9a of the hopper 9 may, if required, be made of different constituents or have varying amounts of the same constituents in areas to assist the compaction of the reinforcing ribs of tiles made therein.
- the Figure 3 modification lends itself for use with a single mortar fed by the conveyor 34.
