Definitions

  • the present invention relates to methods and apparatus for stacking raw bricks on a conveyor, for instance on tunnel-kiln cars.
  • An object of the invention is to accelerate the automatic stacking of raw bricks and at the same time to carry out this operation in such a manner that the raw bricks are stacked cleanly on the conveyor or tunnel-kiln car.
  • apparatus for stacking the raw bricks includes a group of individual gripper members arranged alongside of each other in what is referred to hereinafter as a gripper assembly for lifting the bricks which Iare disposed in rows in intimate engagement with each other laterally.
  • Each individual gripper member is designed to grasp a row of raw bricks at its ends, the bricks preferably being arranged end to end within each row.
  • the gripper assembly is therefore capable of lifting several rows of bricks lat one time, and while thus suspending the bricks, the individual grippers are moved apart a desired distance, so that when the bricks are deposited on the conveyor, they are spaced properly for drying purposes.
  • Such an arrangement makes it possible to deposit the raw bricks at different distances apart and furthermore, as will be more apparent hereinafter, to form the deposited layers of courses of rows of bricks which are staggered so that the stack has substantially better stability on the conveyor.
  • it is ralso possible to grasp the raw bricks in precise position and after being thus grasped, to impart to them any desired spacing yfrom one row of bricks to the next.
  • the spacing may also be varied within each row.
  • One suitable embodiment of the invention is characterized by the fact that a plurality of individual grippers are supported on a gripper-mounting frame having a track along which they can move in order to spread the rows of lbricks apart.
  • Power means such as iluid cylinders, are provided in order to move the individual grippers the desired distance apart.
  • the individual grippers may be 'arranged side by side with elongated members or rods disposed transversely of them, said rods having correspondingly arranged driving means interconnecting the rods and individual grippers, so that when the rods are displaced axially by the fluid cylinders, the individual grippers are moved apart and the desired spacing between the bricks is established. This arrangement is referred to hereinafter as spreader means.
  • the driving means interconnecting the rods and individual grippers consists of several-for instance three-rows of projections extending radially outwardly from the periphery of the rod.
  • driving plates are provided on each individual gripper, through which the rods extend, each driving plate having lCC recesses corresponding to all but one of the rows of projections on said rods.
  • the rods themselves are rotatably mounted in such a manner that in any predetermined angular position, longitudinal displacement of the rods will cause only one row of projections to strike ⁇ against the corresponding driving plates and thus displace the individual grippers transversely to their prescribed positions.
  • Each individual gripper is also provided with adjustable stops which limit the clamping movement of the clamping jaws or gripper arms and make it possible to stagger the raw bricks in one row with the bricks in adjacent rows.
  • the purpose of staggering the rows in this manner is to stack the layers of bricks so that the bricks will be staggered with respect to each other from one layer to another in order to improve drying, as well as to make the pile of bricks more stable.
  • a sequence of operations for stacking raw bricks may be used, whereby several groups or rows of bricks are rst supplied from a brick elevator by lifters, whereupon they are pushed onto a conveyor which shoves the rows rmly together in a lateral direction against a stop on va platform, where an automatic gripper assembly picks them up, actuation of the gripper-assembly being initiated by said stop.
  • 'Ihe stop can consist, 'for instance, of an electric contact which closes a circuit to the control system for the gripper assembly.
  • raw lbricks at one location are fed several abreast to a shove-olf platform, from which the raw bricks are alternately ejected in rows, first to one side and then the other, onto oppositely moving conveyors comprising a so-called shove-off path.
  • the rows of lbricks are pushed into intimate engagement with each other laterally -by means of the shove-olf mechanis-m.
  • the raw bricks are picked up at each end :of the shove-olf path by gripper assemblies in such a manner that the individual grippers grasp the rows of bricks along their longitudinal axes, while they are pushed together side by side.
  • the individual grippers are moved the desired distance apart within each gripper assembly, .and nally the two gripper assemblies are moved on overhead tracks extending transversely of, and more particularly at right angles to, the shove-off path so that the two gripper assemblies form two stacks side by side on a single conveyor extending parallel to the shove-off path.
  • This system includes a shove-01T chain which has a pusher that travels back ⁇ and forth with the chain for the alternate ejection of the raw bricks from the shove-off platform.
  • FIGS. 1 and 2 are side elevation and top plan views, respectively, of a brick stacking or piling installation embodying certain features of the invention
  • FIG. 3 is a front elevation of the gripper assembly shown in broken lines in FIG. 1 and looking inthe direction of the conveyor, the construction of an individual gripper member of said gripper assembly being clearly shown;
  • FIG. 4 is a side elevation of the gripper ⁇ assembly shown in FIG. 3;
  • FIG. 4A is a perspective View of the gripper assembly shown in FIGS. 3 and 4;
  • FIG. 5 is a top plan view of a stack or pile of bricks illustrating how the bricks may be staggered from row to row and from layer to layer;
  • FIG. 6 is an enlarged detail view of the driving means for separating the individual grippers shown in FIGS. 3 and 4;
  • FIG. 7 is an enlarged detail view in perspective of a part of the driving means
  • FIG. 8 is a diagram illustrating the spacing of the individual grippers and rows of bricks held thereby after the individual grippersy have been separated from the position shown in FIG. 4;
  • FIG. 9 is a top plan view of a modified brick stacking installation
  • FIG. 10 is a view similar to FIG. 9 of another modification.
  • FIG. l1 is an elevational view on an enlarged scale of the brick shove-off mechanism employed in the modication of FIG. 10.
  • FIGS. 1 and 2 a number of rows of bricks, depending on the width of the stack to be made, is supplied from a conventional brick elevator 1 by a lifter 1a, both shown purely schematically in the drawings.
  • the bricks have been arranged end to end in rows of three and spaced from each other endwise as well as between rows.
  • the bricks are transferred to a conveyor 2 so that the rows are disposed transversely thereof.
  • Conveyor 2 then carries them to a compacting device where they are shoved tightly together on a platform 3 against a stop 4 for their removal by automatic grippers to be described in detail hereinafter.
  • Suitable means for shoving the bricks together on platform 3 include power-driven endless belts 3a which lift the bricks slightly off the conveyor 2 and carry them against stop 4, which consists of a fixed member extending across the full width of conveyor 2. Stop 4 actuates a gripper assembly designated 20 in FIG. 1 by means of an electric contact which directly or indirectly starts the gripper drive (not shown) in order to lower the gripper assembly 20 into position so that its individual gripper members 7 can grasp the outer ends of each row of bricks on platform 3, in the manner shown in FIG. 3.
  • the individual bricks 21 are most desirably arranged end to end within each row and are lifted off in this position by the individual grippers 7 which correspond in number and spacing with the rows of brick on platform 3. Due to the fact that the individual bricks within each row are tightly pressed together endwise by the individual grippers which are arranged directly alongside each other while they are being lifted, the layer of bricks thus gripped has excellent stability during its transfer. Moreover, at the time each of the grippers 7 grasp the bricks, the rows mutually support each other laterally in order to prevent the bricks from twisting out of alignment or buckling in the middle during the critical initial contact of the grippers therewith, as they are shifted lengthwiseinto tight end to end engagement.
  • Al gripper arrangement such as used for stacking brick in accordance with the present invention, will now be explained with reference to FIGS. 3-8.
  • the gripper assembly shown in FIGS. 3, 4 and 4A consists of a series of individual grippers 7 arranged side by side, each gripper 7 extending in the same direction as the rows of bricks 21 (i.e. transversely of conveyor 2).
  • Each individual gripper 7 is suspended for lateral displacement by means of a transversely extending supporting beam 5 which is slideably supported on a horizontal track 5a disposed longitudinally of conveyor 2 when the bricks 21 are being removed from platform 3.
  • Track 5a in turn is mounted on a suitable hoist (not shown).
  • Spreader means are provided for separating the individual grippers 7 on their track 5a.
  • Such means includes a set of elongated members or rods 1t? which extend through openings provided in each of the beams 5 of the intermediate grippers 7 for limited longitudinal movement with respect thereto.
  • One each rod 10 are provided longitudinally spaced radial projections 11, 11a and 11b (FIGS. 6 and 7), which engage driving plates 6 on the intermediate grippers 7.
  • rods 10 are located on opposite sides and about equidistant from the center line of the gripper assembly. Two such rods are used on each side, each being fixed at its outer end to the outermost gripper 7.
  • the rods in the pair of rods 10 on each side of the gripper assembly extend inwardly toward each other through one-half of the individual grippers 7 with the innermost projections 11 on each rod disposed inwardly of the two central grippers 7.
  • the free ends of rods 10 are located adjacent to but not in contact with each other at the center of the assembly. By drawing the outermost grippers 7 outwardly from the position shown in FIG. 4, the rods 10 are moved so that their projections 11.
  • the spreader means above referred to further includes a pair of power ⁇ cylinders 9 at each end of track 5a, each cylinder being mounted at its outer end to a bracket B depending downwardly from a horizontal beam B rigidly secured to the underside of track 5a for the individual grippers 7.
  • the piston rods of power cylinders 9 are connected to the supporting beams 5 of the outermost grippers 7 in order to accomplish the above-described spreading action of the individual grippers and thereby establish their spacing.
  • the driving elements on rods 10 consist of several, for instance three,.longitudinally extending rows of projections 11, 11a and 11b equally spaced circumferentially about the periphery of each -rod (the row of projections 11b is not visible in FIG. 7).
  • Driving plates 6 are provided with two internal recesses, 8 which correspond in their circumferential spacing to all but one of the rows of projections 11, 11a and 1l1b on rods 10.
  • the rods 10 are so constructed that they can be turned about their longitudinal axes, so that -at a predetermined angular position of rods 10 only the projections 11,-for example, of one row of projections will not register with one of the recesses 8 and will therefor strike against the corresponding driving plates 6 and thus move the individual grippers 7 into the desired position.
  • the individual rows of raw bricks are .thus pulled apart to any desired spacing depending on the longitudinal spacing of the projections 1v1 i on rod 10. Such spacing may be uniform or varied as desired.
  • Each individual gripper 7 is provided with a pair of gripping arms 22 pivoted to the outer ends of its supporting beam 5 in the manner vbest shown in FIG. 3.
  • a pair of power cylinders 7b each fastened at one end to beam 5 and with its piston rod pivoted to one of the gripping arms 22, are arranged so as to draw the lower ends of gripping arms 22 into gripping engagement with the opposite ends of one row of bricks to be stacked.
  • the rows of bricks may be staggered lengthwise by limiting the pivotal movement of certain of the gripping arms so that as the gripping arms grasp the bricks one of the arms is permitted to pivot inwardly farther than the other, thereby shifting the bricks in that row to one side.
  • Adjacent grippers 7 m-ay be adjusted so that the bricks in those rows remain centered or may be moved to the opposite side as they are being grasp-ed by the grippers 7.
  • each individual gripper 7 is provided with adjustable stops 12 adjacent the pivot point of each of its gripping arms 22.
  • Any suitable type of stop yfor limiting the pivotal movement of arms 22 may be employed.
  • a bolt 12a may be threaded through a lug on each a-rm 22 so that its inner end is disposed for abutment with a stop lug 12b on the underside of supporting beam 5.
  • By turning bolts 12a in or out to limit the movement of arms 22, various positions of the rows of bricks in a lengthwise direction can be obtained.
  • the individual rows of raw bricks are thus displaced longitudinally with respect to each other so as to obtain a staggered pile construction such fas that shown in FIG. 5.
  • intermediate tongues 23 extend on resilient rods 23a downwardly from the supporting beams 5 and are disposed between the ends of each of the ⁇ bricks 21, in order to space the bricks from each other within each row when they are pushed together during the lifting operation.
  • Rods 23a may pivot or bend slightly to one side in order to permit the rows of brick to be shifted lengthwise.
  • the apparatus in accordance with the invention operates in such manner that the raw bricks are picked up by the gripper jaws while the individual grippers are initially disposed closely .adjacent each other so that they will register with the rows of bricks which have been shoved into engagement with each other as shown in FIG. 4.
  • the individual grippers are pulled apart into the desired position by rods 10, for instance in the manner indicated schematically in FIG. 8; whereupon the raw bricks are set down on a stack being built on ra conveyor car, for example.
