Definitions

  • the present invention relates to casted concrete block manufacturing and, more particularly, to an apparatus and method for roughing blocks to give them a worn or rough appearance.
  • the concrete block casting industry is well developed and is highly automated in its process operations for manufacturing conventional rectangular concrete blocks and the like.
  • the casted blocks have a geometrically uniform rectangular prism configuration in which the surfaces thereof are substantially planar with adjacent surfaces delimited by sharp edges.
  • a known method consists in disposing the casted blocks in large tumbling drums. These tumbling drums are rotated about their longitudinal axis in order for the concrete blocks to tumble therein and to collide in order to get damaged.
  • This method although producing a generally satisfying look, entails substantial costs due to unrepairable damages to concrete blocks. Some blocks are damaged to a point where they may no longer be used and are thus thrown away or recycled. Also, some concrete block patterns may contain blocks of different sizes and these must be sorted and assembled, which is very time consuming. Also, if a particular one of the blocks in pattern is destroyed more than other blocks, then often the other blocks are no longer useful as a ratio of blocks must be kept. By its nature, the tumbling drum requires frequent repairs. Furthermore, the personnel used for these purposes must deal with a noisy environment due to the tumbling action, and injuries are frequent due to the hazardous operations and handling required thereby. It is difficult to maintain a stable labour force for this work.
  • U.S. Patent No. 5,133,915, issued on July 28, 1992 to Metten et al. discloses a surface upon which a plurality of concrete blocks are disposed in a spaced apart relationship.
  • a roller brush translates over the surface of concrete blocks in a reciprocating manner, thereby stripping and roughing the surface of the concrete blocks.
  • this method provides substantial advantages over the tumbling drum method described above, it requires that the concrete blocks are spaced apart in order for the sharp edges thereof to be treated. Otherwise, only the top surface would be abraded.
  • the brush type roller provides a relatively uniform abrasion of the concrete blocks, which is not a desired result for use with paving blocks.
  • the brush can only strike them at a certain velocity in order not to displace them. If they are displaced, they may end up in abutment with one another, whereby only the top surfaces will be abraded, leaving the sharp edges of the block intact.
  • These blocks are usually treated before the concrete is cured. This patent could not provide the desired result of producing an irregular roughened appearance to concrete blocks.
  • the apparatus consists in slitting a slug of soft clay to form rectangular bricks. These bricks are projected in ultimate sequence under rolls which have opposed textured peripheral flanges whereby to impart a repetitive shape into the clay to simulate an old brick. This shape is only imparted along the opposed longitudinal,edges on one side of the soft clay bricks. The bricks are tilted under associated rolls and the reason for alternate rolls being tilted is to accommodate the impressing rollers.
  • the present invention provides an apparatus for roughing at least one of surfaces and edges of solid concrete casted blocks.
  • the apparatus comprises a block support surface having at least two surface sections.
  • At least a first roughing device having a plurality of impacting elements thereon is provided for roughing concrete blocks.
  • Conveying means is provided for displacing concrete blocks over the surface sections.
  • the apparatus is characterized in that the surface sections have a straight front edge and a rear end edge disposed parallel to one another and extending across the width of a travel path of a plurality of the blocks being conveyed in side-by-side relationship.
  • a first of the surface sections has the rear end edge thereof disposed above an adjacent front end edge of a second of the said surface sections to create a ledge for projecting a leading edge portion of concrete blocks conveyed over the first surface section.
  • the first roughing device is disposed a predetermined distance above the block support surfaces and generally above the rear end of the first surface section for roughing concrete casted blocks in a non-uniform fashion as a projecting leading edge portion of each of the casted concrete blocks as they are conveyed over the rear end.
  • the casted blocks are tilted when reaching a predetermined position over the ledge to fall on a second of the two surface sections at the straight front edge thereof.
  • a method for roughing portions of solid concrete casted blocks is characterized by the steps of conveying a plurality of concrete casted blocks by conveying means with the blocks disposed in side-by-side aligned relationship over a block support surface disposed parallel to one another. At least a section of the support surface is inclined to create a ledge at the rear end edge extending across a panel path of the plurality of concrete casted blocks in side-by-side relationship for projecting a leading edge of the concrete blocks conveyed over the ledge.
  • At least a roughing device is provided and has a plurality of impacting elements thereon and disposed a predetermined distance above the block support surface forwardly of the rear end edge. The leading edge portion of the concrete blocks which are in side-by-side relationship are impacted by the roughing device as they are projected over the ledge by the conveying means. The blocks are tilted when reaching a predetermined position over the ledge.
  • an apparatus for roughing concrete blocks i.e. bricks, paving stones, wall retaining blocks, masonry stones
  • the apparatus 10 comprises a table 11 having a top surface 12, a front end 13, a rear end 14 and lateral sides 15 and 16.
  • the top surface 12 is defined by rectangular panels 17, 18, 19 and 20. It is observed that the rectangular panel 17 is at the front end 13 of the table 11, whereas the rectangular panel 20 is at the rear end 14 thereof.
  • the rectangular panels 17, 18 and 19 are each secured to the table 11 in a slanted or inclined position with respect to the horizontal, such that each of the rectangular panels 17 and 18 has its front side edge lower than its rear side edge. Rectangular panel 19 is flat on the table for reasons which will be described later. Consequently, as seen in Fig. 1, a rear side edge 17R of the rectangular panel 17 is vertically offset with respect to adjacent front side edge 18F of the rectangular panel 18, such as to be above it to create a ledge L. It is pointed out that there is a similar relation between the front side and rear side edges of the rectangular panels 18 and 19. It is also pointed out that the rectangular panel 20 is substantially horizontal and in a co-planar relationship with the rectangular panel 19.
  • Its rear side edge 20R represents the rear end 14 of the table 11.
  • the present invention is not restricted to four rectangular panels as fewer or more rectangular panels could form the table 11.
  • the successive rectangular panels being cascaded could each have been in a horizontal position rather than in a slanted position, with a decrease in vertical positioning from the front end 14 of the table 11 to the rear end 15 thereof, such as to, again, have a cascading relation between the rectangular panels.
  • Support posts 25A and 25B project upwardly from the lateral sides 15 and 16, respectively, of the table 11 on opposed sides of the junction of the rectangular panels 17 and 18. Similar support posts 26A and 26B, and 27A and 27B are upwardly extending at opposed sides of the junctions of the rectangular panels 18 and 19, and of the rectangular panels 19 and 20, respectively.
  • Each of the support posts has at a top end thereof a throughbore having a journal bearing therein (not shown).

  • a plurality of chain link sections 34 are secured to the support bars 32, and are comprised of at least two interconnected loop chain links. The support bars 32 extend through an end loop of each chain link section 34.
  • the roughing tool 30 is rotated by a motor M1 connected to the drive shaft 33A by a belt B1 and pulley P1 assembly.
  • the motor M1 may consist a variable speed electric motor.
  • the roughing tools 40 and 50 are journaled between the support posts 26A and 26B, and 27A and 27B, respectively.
  • the roughing tools 40 and 50 comprise the same elements as the roughing tool 30. Therefore, the roughing tools 40 and 50 will not be described.
  • like elements will be related by having like last digits.
  • the disks 31A and 31B for the roughing tool 30 are generally identical to the disks 41A and 41B of the roughing tool 40.
  • the disks 51A and 51B of the roughing tool 50 are generally identical to the disks 31A of the 31B of the roughing tool 30.
  • the motors and belt/pulley assemblies driving the roughing tools 40 and 50 are not shown.
  • the slanted or inclined positioning of the rectangular panels 17 and 18, whereby they are cascaded, allows for given portions of the concrete blocks C disposed on the top surface 12 of the table 11 to be exposed to the chain link sections 34 and 44 of the roughing tools 30 and 40, respectively, during their travel over the panels and specifically over the ledges.
  • the configuration of the rectangular panel 17 with respect to panel 18 allows for only an edge C' of a concrete block C to be exposed for being impacted by the chain link sections 34 as it is conveyed by the conveyor bars 65 over the ledge L.
  • the block C will tilt down and fall on the rectangular panel 18, and its top surface will avoid the chain link sections 34.
  • the roughing tools 30, 40 and 50 may be positioned strategically with respect to the table 11 in order for predetermined portions of the concrete blocks C to be abraded.
  • the slanted configuration of the rectangular panels 17 and 18 allows for only the exposed edge portions of the concrete blocks C to be roughened.
  • three roughing tools are provided in order to treat the concrete blocks C disposed thereon for various effects.
  • the roughing tool 30 is positioned to strike the exposed edges C' of the concrete blocks C such as to do a rough treating thereof and remove bigger chunks of material.
  • the roughing tool 40 is positioned such as to treat the edges of the blocks C to a smoother finishing.
  • rectangular panel 19 is flat and the roughing tool 50 is positioned to abrade the top surface C'' of the blocks C.
  • the roughing tools 30, 40 and 50 are driven by a variable speed motor (not shown) and may thus be rotated to various speeds in order to impact the concrete blocks C at various forces. They can also be independently driven. As seen in Fig. 3, a bolt B and nuts N have been added to an end chain link of a chain link section 34 such as to provide a random pattern on the concrete blocks C upon same being struck.
  • the apparatus 10 is provided with a conveyor 60 to displace the concrete blocks C over the panels 17, 18, 19 and 20.
  • the conveyor 60 comprises a pair of chain loops 61A and 61B adjacent the lateral sides 15 and 16, respectively, of the table 11.
  • the chain loop 61A is operatingly held about a pair of sprockets 62F and 62R, with the sprocket 62R being driven by a motor M2 and a belt B2 and pulley P2 assembly.
  • the chain loop 61B is disposed about a sprocket 63F and the driven sprocket 63R, the latter being connected to an opposed end of an axle 64 upon which is secured the sprocket 62R.
  • the chain loops 61A and 61B are linked by a plurality of bars 65 which are equidistantly spaced.
  • the bars 65 come in contact with the concrete blocks C disposed on the top surface 12 of the table 11 such as to displace the concrete blocks C from the front end 13 to the rear end 14 thereof.
  • the motor M2 may be of various speeds in order to provide various velocities to the blocks moving forward.
  • a plurality of apparatuses for roughing concrete blocks or tables in accordance with the present invention may be provided in series in order to treat the various edge surfaces and top surfaces of the concrete blocks C.

  • 40A similar edge finish
  • elements of an apparatus have been affixed a like letter (for instance, roughing tool 30A of apparatus 10A).
  • the concrete blocks C are then transferred to a transfer table 100A, where a push bar 101A will load the concrete blocks C to apparatus 10B. It is pointed out that the front side edges of the concrete blocks C will now be treated as a consequence of the apparatus 10B being perpendicular to the apparatus 10A.
  • the concrete blocks C will then move onward to the apparatuses 10C and 10D through the transfer tables 100B and 100C, respectively, so as to be treated on all side edges.
  • a third roughing tool 50D is provided on the apparatus 10D to treat the top surface of the concrete blocks C. This operation only requires to be achieved once as all side edges of the concrete blocks C share the same top surface.
  • the concrete blocks can be loaded on to a stack of concrete blocks (not shown) by transfer table 100D at an end of the series of apparatuses. It is observed that a plurality of concrete blocks C are treated at a same time on the series of apparatuses, whereby this configuration advantageously allows for a continuous output of treated concrete blocks.
  • the panels forming the block support surface of the apparatuses may be solid. It has also been thought to provide a grid surface, as shown at G for one of the panels of apparatus 10B in Fig. 4, so that concrete particles resulting from the concrete blocks being treated fall through the grid surface G to the floor, thereby not accumulating on the top surface of the panels.
  • FIG. 5 a further embodiment of the apparatus 10 is shown, wherein the concrete blocks C will be abraded from a roughing tool 60, similar to the roughing tools 30, 40 and 50 described above, but disposed underneath the top surface 12, herein shown below rectangular panels 17 and 18.
  • the rectangular panels 17 and 18 in this embodiment are shown further spread apart by a gap G2, as well as being offset by ledge L, to allow for the bottom trailing edges of concrete blocks C to drop in the gap G2 to be exposed to the abrading chain link sections 64 of the roughing tool 60 to be abraded thereby.
  • Guides (not shown) are provided such that the bars 65 and the chain loops 61A and 61B avoid the chain link sections 64 of the roughing tool 60 when moving across the gap G2.
  • the roughing tool 60 is depicted once more underneath the top surface 12 of the roughing apparatus 10, yet the rectangular panels 17 and 18 are not offset by the ledge L, whereby the concrete blocks driven across the gap G will have their bottom trailing surfaces exposed to be abraded by the chain link sections 64' of the roughing tool 60'.
  • the roughing tool below the top surface 12 ensures that the chips or the dust resulting from the abrading action on the concrete blocks C will not accumulate on the top surface 12 of the apparatus 10.
  • the roughing tool below the top surface 12 are used in combination with roughing tools disposed above the top surface 12 of the apparatus 10, as described above, whereby two opposed sides and edges of the concrete blocks C are abraded on the same apparatus.
